Abstract
Soil acidification often suppresses microbial growth and activities, resulting in a negative impact on soil organic carbon (C) decomposition. While the detrimental effects of acidification on soil and plant properties have been extensively studied, less attention has been paid on the shifts in soil microbial communities and their influences of the decomposition of organic C with different chemical complexities. Taking advantage of an acid addition experiment in a Tibetan alpine meadow, here we examined the response of soil microbial communities to soil acidification and microbial effect on the decomposition of organic C with different chemical complexities (i.e., glucose and lignin, representing labile and recalcitrant C respectively). We found that soil acidification had no impact on microbial respiration and microbial abundance even though it decreased bacterial diversity significantly. Soil acidification increased the relative abundance of some microbial taxa, like Alphaproteobacteria and Acidobacteriia in bacteria increased by 36 %, 284 %, and Eurotiomycetes, Sordariomycetes and Leotiomycetes in fungi increased by 145 %, 279 % and 12.7-fold, but decreased the relative abundance of Acidimicrobiia by 33 % in highest acid addition treatment. Changes in microbial communities (bacterial and fungal community composition, the diversity of bacterial community and the ratio of fungi to bacteria) are significantly related to the decomposition of glucose and lignin. More specifically, soil acidification decreased the decomposition of glucose but increased the decomposition of lignin, indicating a trade-off between the decomposition of labile and recalcitrant soil organic C under soil acidification. Overall, shifts in microbial communities under soil acidification might be accompanied by an increased ability to break down more recalcitrant C. This trade-off between the decomposition of labile and recalcitrant C may change soil C quality under future acid deposition scenarios.

Abstract
Organic amendments can improve soil fertility and microbial diversity, making agroecosystems more resilient to stress. However, it is uncertain whether organic amendments will enhance the functional capacity of soil microbial communities, thereby mitigating fluctuations in microbial respiration caused by environmental changes. Here, we examined the impacts of long-term organic amendments on the dynamics of microbial catabolic capacity (characterized by enzyme activities and carbon source utilization) and microbial respiration, as well as their interrelationships during a period with fluctuating temperature and rainfall in the field. We then subjected the field soil samples to laboratory heating disturbances to further evaluate the importance of microbial catabolic capacity in explaining patterns of microbial respiration. In both field and laboratory experiments, organic amendments tended to increase the stability of microbial catabolic capacity, but significantly increased the vulnerability of microbial respiration to environmental changes. However, the direction and driving factors of microbial respiration affected by environmental changes differed between the field and laboratory experiments. Environmental changes in the field suppressed the promotional effects of organic amendments on microbial respiration mainly through reducing microbial catabolic capacity, while laboratory heating further enhanced microbial respiration mainly due to increased soil resource availability. Together, these findings suggest that increased microbial respiration variations under organic amendments may potentially increase the uncertainty in predicting soil carbon emissions in the scenario of ongoing climate/anthropogenic changes, and highlight the necessity of linking laboratory studies on environmental changes to field conditions.

Abstract
Objective: To explore the short-term efficacy of perioperative fecal microbiota transplantation combined with nutritional support in patients with radiation-induced enteritis complicated by intestinal obstruction. Methods: The cohort of this prospective cohort study comprised 45 patients (nine men and 36 women) with radiation-induced enteritis complicated by intestinal obstruction admitted to Shanghai Tenth People's Hospital Affiliated to Tongji University from January 2022 to October 2022. The median age was 53 (42-65) years. Thirty-five of the patients had gynecological tumors and 10 colorectal malignancies. The patients were randomly allocated to a fecal microbiota transplantation group of 20 patients who underwent fecal microbiota transplantation starting 2 weeks before surgery for 6 days, in addition to receiving conventional perioperative treatment, and a conventional treatment group of 25 patients who only received nutritional support during the perioperative period. There were no significant differences in baseline characteristics (sex, age, preoperative nutritional indices, and surgical procedure) between the two groups (all P>0.05). Postoperative recovery (time to passing flatus or a bowel movement, length of stay) and complications were compared between the two groups. Postoperative complications within 30 days after surgery classified in accordance with the international Clavien-Dindo classification of surgical complications (I-V) were statistically analyzed. Improvement in gastrointestinal symptoms, namely abdominal pain, distension, diarrhea, and rectal bleeding) and gastrointestinal quality of life scores (which include 36 problems rated 0-144 points related to physical, psychological, social activities and family life; the lower the score, the more severe the symptoms) were compared between the two groups. Nutritional recovery was assessed by body mass, body mass index, total protein, albumin, prealbumin, and hemoglobin. Results: Compared with the conventional treatment group, the postoperative hospital stay was shorter in the fecal microbiota transplantation group (8.0±4.3 days vs. 11.2±5.4 days, t=2.157, P=0.037) and the time to passage of flatus or having a bowel movement was earlier (2.2±3.2 days vs. 3.9±2.3 days, t=2.072, P=0.044). There were 26 postoperative complications in the fecal microbiota transplantation group and 59 in the conventional treatment group. There were 20 and 36 Grade I to II complications and no and three Grade III to V complications in the transplantation and conventional treatment group, respectively. The overall grade of complication did not differ significantly between the two groups (P=0.544). However, the incidence of postoperative intestinal inflammatory obstruction was lower in the fecal microbiota transplantation than the conventional treatment group (10.0% [2/20] vs. 40.0% [10/25], P=0.040). One patient in the conventional treatment group died. This patient had complete intestinal obstruction complicated by severe malnutrition preoperatively, and an intestinal fistula complicated by abdominal infection postoperatively, and died despite active treatment. Nineteen and 23 patients in the transplantation and conventional treatment group, respectively, attended for follow-up 1 month after surgery; 19 and 21, respectively, attended for follow-up 3 months after surgery, and 17 and 20, respectively, attended for follow-up 6 months after surgery. There were no significant differences between the two groups in abdominal pain or rectal bleeding 1, 3, or 6 months after surgery (all P>0.05). One month after surgery, the incidence of abdominal distension and diarrhea was lower in the fecal microbiota transplantation than in the conventional treatment group (3/19 vs. 48.0% [11/23], P=0.048; 3/19 vs. 52.2% [12/23], P=0.023). However, at the 3 and 6 month follow-ups the incidence of abdominal distension and diarrhea had gradually decreased in both groups and the differences between the groups were not statistically significant (P>0.05 for all). Scores for gastrointestinal quality of life improved significantly in both treatment groups compared with preoperative values (F=71.250, P<0.001; F=79.130, P<0.001, respectively). Scores for gastrointestinal quality of life were higher in the fecal microbiota transplantation than the conventional treatment group at all follow-up time points (P<0.05). One-way ANOVA showed that body mass, body mass index, and total protein, albumin and hemoglobin concentrations improved in both groups compared with preoperative values (all P<0.05). Prealbumin concentration improved significantly in the transplantation (F=5.514, P=0.002), but not in the conventional, group (F=1.535, P=0.211). The improvements in body mass, body mass index, total protein, and albumin were better in the fecal microbiota transplantation than conventional treatment group at 3 and 6 months of follow-up (all P<0.05). Conclusion: Perioperative fecal microbiota transplantation combined with nutritional support is effective in improving early postoperative nutritional status and quality of life in patients with radiation-induced enteritis complicated by intestinal obstruction.

Abstract
OBJECTIVE To investigate the genetic diversity and genetic differentiation of different geographical isolates of Gohieria fusca. METHODS G. fusca isolates were sampled from Wuhu (WH), Bengbu (BB) and Bozhou cities (BZ) of Anhui Province and Jiaxing City of Zhejiang Province (JX). Mitochondrial cytochrome b (Cytb) and ribosomal internal transcribed spacer (ITS) genes were amplified in WH, BB, BZ and JX isolates of G. fusca using PCR assay. The gene sequences were edited and aligned using the software Chromas 2 and DNASTAR 1.00, and the haplotype, haplotype diversity (Hd) and nucleotide polymorphism (Pi) of each isolate were calculated using the software DnaSP 5.10.00. The genetic differentiation among isolates (Fst) and gene flow value (Nm) were estimated using the software MEGA 10.2, and a phylogenetic tree was built. Tests of neutrality and analysis of molecular variance (AMOVA) were performed using the software Arlequin 3.1 and a haplotype network was built based on the Median-Joining network using the software Network 10.2. RESULTS PCR assay showed that the sizes of the Cytb and ITS genes were 372 bp and 1 301 to 1 320 bp, respectively. All four isolates of G. fusca presented high genetic diversity based on mitochondrial Cytb and ITS genes (Hd = 0.804, Pi = 0.006 91). AMOVA showed genetic differentiation among geographical isolates of G. fusca (Fst = 0.202 40, P < 0.05), and the genetic variation was mainly caused by intra-population variations (79.76%). Gene flow analysis showed a high level of gene flow among G. fusca isolates (Nm > 1). Tests of neutrality based on Cytb gene measured a Tajima's D value of -1.796 31 (P < 0.05) and a Fu's FS value of -3.293 98 (P < 0.05) in WH isolate of G. fusca, indicating population expansion in WH isolate of G. fusca. Haplotype network analysis and phylogenetic analysis revealed no remarkable geographical distribution pattern among different geographical isolates of G. fusca. All four isolates of G. fusca presented high genetic diversity (Hd = 0.985, Pi = 0.011 97). AMOVA showed moderate level of genetic differentiation between four isolates (Fst = 0.104 62, P < 0.05). The tests of neutrality based on ITS genes measured a Tajima's D value of -6.088 20 and a Fu's FS value of -1.935 99 (both P > 0.05) in the whole isolate of G. fusca, indicating no obviously population expansion. CONCLUSIONS The four geographical isolates of G. fusca have high genetic diversity and remarkable genetic differentiation. Since a high level of gene flow is detected among different geographical isolates of G. fusca, no obvious geographical distribution pattern of G. fusca is found.

Abstract
Cuticular proteins (CPs) are a large family and perform a variety of functions. However, the physiological roles of cuticle protein 21-like (Cpr21L) in the brown planthopper (Nilaparvata lugens, BPH), one of the most destructive insect pests of rice, are largely unclear. In this study, Cpr21L was revealed to be expressed in both BPH nymphs and adults, and the mRNA expression level was much higher in male adults than female adults. Spatially, the expression of Cpr21L in the testis was higher than in the ovary. The RNA interference (RNAi) of Cpr21L seriously decreased nymph survival, and no individual survived 8 days post-dsCpr21L injection. The RNAi of Cpr21L in adults also decreased the fertility of males, especially in the dsCpr21L♂ × dsGFP♀ group. The average number of eggs laid by one female in this group significantly decreased by 50.1%, and the eggs' hatchability decreased from 76.5% to 23.8% compared with the control (dsGFP♂ × dsGFP♀). Furthermore, observations under a stereomicroscope showed that the RNAi of Cpr21L severely impaired the development of the testes. Therefore, Cpr21L is essential for the nymphal survival and male fecundity of BPH, thus providing a possible target for pest control.

Abstract
Dissolved organic matter (DOM) plays a vital role in biogeochemical processes and in determining the responses of soil organic matter (SOM) to global change. Although the quantity of soil DOM has been inventoried across diverse spatio-temporal scales, the underlying mechanisms accounting for variability in DOM dynamics remain unclear especially in upland ecosystems. Here, a gradient of SOM storage across 12 croplands in northeast China was used to understand links between DOM dynamics, microbial metabolism, and abiotic conditions. We assessed the composition, biodegradability, and key biodegradable components of DOM. In addition, SOM and mineral-associated organic matter (MAOM) composition, soil enzyme activities, oxygen availability, soil texture, and iron (Fe), Fe-bound organic matter, and nutrient concentrations were quantified to clarify the drivers of DOM quality (composition and biodegradability). The proportion of biodegradable DOM increased exponentially with decreasing initial DOM concentration due to larger fractions of depolymerized DOM that was rich in small-molecular phenols and proteinaceous components. Unexpectedly, the composition of DOM was decoupled from that of SOM or MAOM, but significantly related to enzymatic properties. These results indicate that microbial metabolism exhibited a dominant role in DOM generation. As DOM concentration declined, increased soil oxygen availability regulated DOM composition and enhanced its biodegradability mainly through mediating microbial metabolism and Fe oxidation. The oxygen-induced oxidation of Fe(II) to Fe(III) removed complex DOM compounds with large molecular weight. Moreover, increased oxygen availability stimulated oxidase-catalyzed depolymerization of aromatic substances, and promoted production of protein-like DOM components due to lower enzymatic C/N acquisition ratio. As global changes in temperature and moisture will have large impacts on soil oxygen availability, the role of oxygen in regulating DOM dynamics highlights the importance of integrating soil oxygen supply with microbial metabolism and Fe redox status to improve model predictions of soil carbon under climate change.

Abstract
Panax notoginseng round spot disease (PRSD), caused by Mycocentrospora acerina, is the main leaf disease occurring in cultured P. notoginseng. Aiming to find a safe and efficient control method for PRSD, we studied the disease characteristics of PRSD and the optimal growth conditions of M. acerina and evaluated the efficacy of rain-shelter cultivation in PRSD control. Moreover, we described M. acerina based on morphological characterization and molecular analyses (ITS, ACT, LSU, and TEF-1α). The optimum temperature for M. acerina conidial germination was found to be 14 to 22°C. Furthermore, leaf surface wetness for at least 4 h is required for conidial germination, and conidia can successfully infect P. notoginseng when the leaf wetness lasts for more than 8 h. Additionally, rainwater splashing determines the conidial transfection distance, which is less than 2 m. Finally, our study revealed that rain-shelter cultivation is an effective and simple physical prevention strategy to control PRSD, with an average efficacy of up to 100%.

Abstract
Objective: To evaluate the efficacy and safety of fecal microbiota transplantation (FMT) in the treatment of autism spectrum disorder (ASD). Methods: A longitudinal study was conducted. Clinical data from ASD patients with gastrointestinal symptoms and who underwent FMT in the Tenth People's Hospital affiliated to Tongji University or Jinling Hospital between May 2012 to May 2021 were retrospectively collected. Scores derived from the autism behavior checklist (ABC), the childhood autism rating scale (CARS), the Bristol stool form scale (BSFS), and the gastrointestinal symptom rating scale (GSRS) were analyzed at baseline and at the 1st, 3rd, 6th, 12th, 24th, 36th, 48th and 60th month after FMT. Records of any adverse reactions were collected. Generalized estimating equations were used for analysis of data on time points before and after FMT. Results: A total of 328 patients met the inclusion criteria for this study. Their mean age was 6.1±3.4 years old. The cohort included 271 boys and 57 girls. The percentage of patients remaining in the study for post-treatment follow-up at the 1st, 3rd, 12th, 24th, 36th, 48th and 60th month were as follows: 303 (92.4%), 284 (86.7%), 213 (64.9%), 190 (57.9%), 143 (43.6%), 79 (24.1%), 46 (14.0%), 31 (9.5%). After FMT, the average ABC score was significantly improved in the first 36 months and remained improved at the 48th month. However, the average score was not significantly different from baseline by the 60th month (1st-36th month, P<0.001; 48th month, P=0.008; 60th month, P=0.108). The average CARS score improved significantly during the first 48 months and remained improved at the 60th month (1st-48th month, P<0.001; 60th month, P=0.010). The average BSFS score was also significantly improved in the first 36 months (with an accompanying stool morphology that resembled type 4). This improvement was maintained at the 48th month. However, the average score was similar to baseline at the 60th month (1st-36th month, P<0.001; 48th month, P=0.008; 60th month, P=0.109). The average GSRS score was significantly improved during the first 24 months, but not afterwards (1st-24th month, P<0.001; 36th month, P=0.209; 48th month, P=0.996; 60th month, P=0.668). The adverse events recorded during treatment included abdominal distension in 21 cases (6.4%), nausea in 14 cases (4.3%), vomiting in 9 cases (2.7%), abdominal pain in 15 cases (4.6%), diarrhea in 18 cases (5.5%), fever in 13 cases (4.0%), and excitement in 24 cases (7.3%). All adverse reactions were mild to moderate and improved immediately after suspension of FMT or on treatment of symptoms. No serious adverse reactions occurred. Conclusion: FMT has satisfactory long-term efficacy and safety for the treatment of ASD with gastrointestinal symptoms.

Abstract
Objective: To summarize and analyze the clinical effect of fecal microbiota transplantation (FMT) combined with nutritional support and psychotherapy in patients with "Tetralogy of Tongji" (comprising chronic gastrointestinal dysfunction, mental and psychological disorders, malnutrition, and endocrine disorders). Methods: A longitudinal study was conducted. The inclusion criteria were as follows: (1) patients were under 70 years of age; (2) patients exhibited chronic gastrointestinal dysfunction (in accordance with the Rome IV diagnostic criteria for irritable bowel syndrome ie. chronic functional constipation, diarrhea, abdominal pain and abdominal distention) with onset occurring more than one year previously; (3) patients exhibited malnutrition (body mass index ≤ 18.5 kg/m2); (4) patients exhibited depression, anxiety, or state as diagnosed by a psychologist using the Hamilton anxiety rating scale (HAMA) and the Hamilton depression scale (HAMD); (5) patients were women of childbearing age with amenorrhea or menstrual disorder with a duration ≥6 months. Patients were excluded if they exhibited gastrointestinal bleeding, short bowel syndrome, radiation-induced intestinal injury, intestinal obstruction or inflammatory bowel disease, recurrent/metastatic tumors, systemic infectious diseases, life-threatening systemic comorbidities, intorlerate to nasojejunal, percutaneous gastrostomy / jejunostomy or FMT. The clinical data of 43 patients at Shanghai Tenth People's Hospital exhibiting the "Tetralogy of Tongji" and who received microflora transplantation combined with nutritional support and psychotherapy from June 2017 to June 2021 was prospectively collected. There were 12 males and 31 females with a mean age of 35.2±16.7 years. All 43 patients had chronic gastrointestinal dysfunction. Of these, 24 patients had depression and 19 had anxiety. There were 26 women of reproductive age, including 13 cases of menstrual disorder and 9 cases of amenorrhea. The treatment intervention was a combination of FMT (microflora solution or microflora capsule), nutritional support (enteral nutrition) and psychological intervention. The following were assessed before treatment and 1, 3, 6 months after treatment: (1) gastrointestinal function was assessed using the gastrointestinal symptoms rating scale (GSRS), where a higher score is indicative of more serious gastrointestinal symptoms, and the gastrointestinal quality of life index (GIQLI), where a higher score is indicative of higher quality of life; (2) psychological status was assessed using HAMA and HAMD scores, where a lower score is indicative of reduced severity of anxiety or depression symptoms, respectively; (3) nutritional status was assessed by measurements of total blood protein, albumin, fibrinogen and prealbumin, as well as measurements of body mass and body mass index (BMI); (4) neuroendocrine function was assessed by measurement of blood levels of cortisol, dopamine and noradrenaline, as well as menstruation in women of reproductive age. Results: The follow-up rates at 1, 3 and 6 months after treatment were 90.7% (39/43), 72.1% (31/43) and 55.8% (24/43), respectively. The total effective rate for chronic gastrointestinal dysfunction was 81.4% (35/43), of which the average GSRS score decreased from 29.35±3.56 before treatment to 18.25±2.56 in the sixth month (P<0.001). The average GIQLI score increased from 56.23±10.34 before treatment to 91.04±20.39 in the sixth month (P<0.001). All patients had malnutrition before treatment. After 6 months, their body weight had increased from 40.61±8.88 kg to 50.45±6.23 kg (P<0.001), and BMI had increased from 15.17±1.87 kg/m2 to 19.58±1.42 kg/m2 (P<0.001). The average total protein level was 60.99± 5.99 g/L before treatment. After 6 months, this had increased to 64.21±4.23 g/L (F=2.715, P=0.022). The average prealbumin level increased from 150.14±56.04 mg/L before treatment to 258.17±86.94 mg/L after 6 months (F=15.124, P<0.001). In this study, 24 patients with depression/depressed state were included. After treatment, the average HAMD score in these patients decreased from 22.79±6.63 before treatment to 9.92±7.24 after 6 months (P<0.001). There were 19 patients with anxiety disorder/anxiety state. After treatment, the average HAMA score in these patients decreased from 17.15±4.34 before treatment to 7.73±4.10 after 6 months (P<0.001). Observing the endocrine efficacy of 26 women of childbearing age, it was found that the effective rate of this treatment on endocrine regulation was 69.2% (18/26). Although there was no significant change in blood cortisol levels after 6 months, average blood dopamine levels decreased from 32.91±10.65 nmol/L before treatment to 13.02±5.58 nmol/L after 6 months (P<0.001). Average blood norepinephrine levels decreased from 49.75±15.23 ng/L before treatment to 19.21±9.58 ng/L after 6 months (P<0.001). Conclusion: The strategy of FMT combined with nutritional support and psychological intervention is effective in improving the symptoms of the "Tetralogy of Tongji".

Abstract
Objective: To explore and establish the preparation system of human intestinal fluid transplantation (HIFT) and HIFT capsule, and to preliminarily apply it to clinic. Methods: Strict standards for donor screening and management were established. The nasojejunal tube was catheterized into the distal jejunum, and then it was connected with an improved disposable sterile negative pressure collection device for the collection of human intestinal fluid. After that, it was prepared into capsules by filtering, adding 10% glycerin protectant and freeze-drying method. The amount of living bacteria was used as the standard of therapeutic dose. The living bacteria amount in fluid is ≥ 5.0×108 /mL and the living bacteria proportion is ≥ 83%; the living bacteria amount in powder is ≥ 2.0×106 /g and the living bacteria proportion is ≥ 81%; The observational indicators included: (1) the basic information of the donor, the amount of living bacteria in the HIF and powder. (2) Preliminary analysis of the treatment for ASD, which combined HIFT capsule with standard FMT capsule, from February to December 2021 (Clinical trial Registration Number: ChiCTR2100043929). Evaluation criteria: Trypan blue staining method was used to detect the living bacteria amount in fluid and powder. The Autism Behavior Checklist (ABC) and Childhood Autism Rating Scale (CARS) were used to evaluate the efficacy. Results: Compared with the parent donor, the standard donor was younger [(25.4±0.9) y vs. (30.7±3.2) y, t=-19.097, P=0.001] and had a lower body mass index [(19.7±0.5) kg/m2 vs. (20.8±1.3) kg/m2, t=-8.726, P=0.001], more in the living bacteria amount in powder [(7.47±1.52)×106/g vs. (5.03±1.38)×106/g, t=11.331, P=0.031], Chao index (205.4±6.8 vs. 194.2±7.2, t=10.415, P=0.001), and Shannon index (3.25±0.14 vs 2.72±0.27, t=19.465, P=0.001). The differences were statistically significant (all P<0.05). However, there were no significant differences in gender, drainage volume and total number of bacterial liquid colonies between the two groups (all P>0.05). Both the standard donor and the parent donor met the donor screening criteria, and the preparation fluid and powder met the treatment criteria. Eight patients received the treatment of HIFT combined with fecal microbiota transplantation (FMT). Preliminary statistical results showed that HIFT combined with FMT improved ABC and CARS at the 1st, 2nd, 3rd and 4th months. The differences were statistically significant (all P<0.05). No severe adverse reaction occurred. Conclusion: Based on the previous research on FMT preparation system and the clinical technology in our center, this study developed a high standard HIFT preparation system, and explored the clinical study of HIFT combined with FMT, in order to provide an innovative therapy for the treatment of diseases.

Abstract
UNLABELLED Scanner mismatch occurs frequently with follow-up dual-energy x-ray absorptiometry (DXA) scans. Nearly one-in-five follow-up DXA scans were conducted on non-cross-calibrated scanners (scanner mismatch) and more than a quarter of patients who had a follow-up DXA scan had experienced scanner mismatch. INTRODUCTION Detecting significant changes in bone mineral density (BMD) with dual-energy x-ray absorptiometry (DXA) scanners relies on the least significant change (LSC). Results from two different DXA scanners can only be compared, albeit with decreased sensitivity for change, if the LSC between the two scanners has been directly determined through cross-calibration. Performing follow-up DXA scans on non-cross-calibrated scanners (scanner mismatch) has safety and economic implications. This study aims to determine the proportion of scanner mismatch occurring at a population level. METHODS All patients who completed at least two DXA scans between 1 April 2009 and 31 December 2018 in the province of Alberta, Canada, were identified using population-based health services databases. Scanner mismatch was defined as a follow-up DXA scan completed on a DXA scanner that differed from and was not cross-calibrated to the previous DXA scanner. Multivariate logistic regression models were used to assess predictive factors that may contribute to scanner mismatch. RESULTS A total of 264,866 patients with 470,641 follow-up DXA scans were identified. Scanner mismatch occurred in 18.9% of follow-up DXA scans; 28.7% of patients experienced at least one scanner mismatch. Longer duration between scans (OR 1.25, 95% CI 1.24-1.26) and major osteoporotic fracture history before index scan (OR 1.06, 95% CI 1.03-1.08) increased risk of scanner mismatch. Osteoporosis medication use before index scan (OR 0.89; 95% CI 0.88-0.91), recency of follow-up scans (OR 0.98, 95% CI 0.73-0.98), female sex (OR 0.97, 95% CI 0.94-1.00), and age at last scan (OR 0.99, 95% CI 0.99-1.00) were associated with lower risk of scanner mismatch. CONCLUSION Scanner mismatch is a common problem, occurring in one-in-five follow-up DXA scans and affecting more than a quarter of patients. Interventions to reduce this large proportion of scanner mismatch are necessary.

Abstract
BackgroundImmune Checkpoint Inhibitors (ICI) have altered the landscape of cancer therapy. However, toxicities are common and up to 80% of patients will develop immune-related adverse events (irAE), including rheumatic irAEs (Rh-irAE), which can often limit their cancer treatment. Our knowledge of clinical manifestations and optimal management of patients with Rh-irAE continues to evolve as these agents are being used to treat a wider variety of cancers. Currently available data is limited to retrospective case series and case reports. There is also scarce data on the use of ICI in patients with pre-existing autoimmune disease (PAD) as these patients are often excluded from clinical trials.ObjectivesTo describe the clinical presentation, management and early outcomes of patients exposed to ICI with Rh-irAE or PAD recruited and followed prospectively from multiple sites across Canada.MethodsAdult patients with Rh-irAE from cancer immunotherapy (CTLA-4, PD-1 or PDL-1 inhibitors) or those with PAD exposed to cancer immunotherapy are prospectively recruited across 9 academic sites in Canada. Standardized clinical and biologic data are also collected. We describe clinical characteristics and management of patients recruited between January 2020 and October 2021, stratified based on the presence or absence of PAD.Results103 patients were recruited from 9 sites. From those, 85 had Rh-irAE, 47 had pre-existing musculoskeletal and rheumatic diseases, and 20 had other PAD. The most frequent Rh-irAE were joint manifestations (n = 73). Other Rh-irAE included muscle symptoms (n = 7), connective tissue disease (n = 6), vasculitis (n=2) and sarcoid (n = 3). Prednisone was the most common treatment (n = 53). Intraarticular corticosteroids were used in 7 patients. Eleven patients required conventional synthetic disease-modifying anti-rheumatic drugs (DMARD) and only one required biologic DMARD to control the Rh-irAE. Anti-PD-1 therapies were the most used ICI (56.3%), followed by combination therapy (35.9%). Response to index immunotherapy at 6 months was available for 21 patients. Most patients had partial response (57.1%) and only 4 patients had tumor progression (19.1%). The ICI was permanently discontinued due to an irAE in 21 patients (38.1% with PAD and 61.9% without PAD). There were no deaths related to Rh-irAE.ConclusionThe initial sample of the CanRIO prospective national cohort suggests that demographic characteristics and tumor representation in people with PAD and without PAD is similar. Patients with PAD are less likely to receive combination therapy (n= 12 vs. n=25) and are less likely to have tumor progression on ICI (n=1) compared to those without PAD (n=3). Selection bias is noted in this initial sample since half of recruited patients have PAD. The CanRIO cohort provides valuable insight into real-world spectrum and management of Rh-irAE secondary to immunotherapy for cancer.Disclosure of InterestsShahin Jamal Grant/research support from: CanRIO has received financial support from BMS and Organon, Lourdes Gonzalez Arreola: None declared, Julia Tan: None declared, Carrie Ye: None declared, Janet Roberts: None declared, Aurore Fifi-Mah: None declared, Marie Hudson: None declared, Sabrina Hoa: None declared, Janet Pope: None declared, Ines Colmegna: None declared, C.

Abstract
UNLABELLED Fractures are associated with increased long-term mortality in patients surviving to undergo baseline DXA. Notably, excess mortality risk does not decline with increasing time since prior hip or humerus fractures, even after accounting for comorbid medical conditions and other risk factors. INTRODUCTION Mortality risk increases following most types of fracture. In routine clinical practice, patients with prior fractures seen for dual-energy X-ray absorptiometry scan (DXA) are "survivors;" whether they remain at increased mortality risk is unknown. We tested the association between prior fracture and all-cause mortality, stratified by time since fracture, in patients undergoing baseline DXA. METHODS We conducted a DXA registry-based cohort study and linked to population-based health services data for the Province of Manitoba, Canada. We identified women and men ≥ 40 years with minimum 10 years of prior healthcare coverage undergoing baseline DXA and ascertained prior fracture codes since 1984 and mortality to 2017. Time since prior fracture was calculated between the clinical encounter for the fracture and baseline DXA (index date). Cox proportional hazards models estimated hazard ratios for all-cause mortality in those with compared to those without prior fracture adjusted for (1) age and sex, and (2) age, sex, comorbidities, and other covariates. RESULTS The study cohort consisted of 74,474 individuals (mean age 64.6 years, 89.7% female). During mean follow-up 9.2 years, we ascertained 14,923 (20.0%) deaths. Except for forearm fractures, all fracture sites were associated with increased mortality risk compared to those without prior fracture, even after multivariable adjustment. Excess mortality risk tended to decline slightly with time since fracture and was no longer significant > 10 years after vertebral fracture. However, excess mortality persisted > 10 years following hip or humerus fracture. CONCLUSIONS Prior fractures are associated with increased long-term mortality in patients surviving to undergo baseline DXA. Excess mortality risk does not decline with time since prior hip or humerus fractures, after accounting for potential confounders. Fracture prevention may have important long-term benefits preserving life expectancy.

Abstract
BackgroundClinical and magnetic resonance imaging (MRI) disease activity score (DAS) are measuring different aspects of axial spondyloarthritis (axSpA), they are essential in disease activity assessment. The radiomics was on facilitating readings by clinical specialists via enhancing the medical images in which subtle data differences could be distinguished.ObjectivesIf the additional information of MRI imaging can be considered as a predictor for axSpA disease activity? In this study, we sought to construct a nomogram integrating the sacroiliac joint (SIJ)- MRI radiomics features and the inflammatory biomarkers to assess disease activity and compare it with clinical disease acitivity index in axSpA patients.Methods203 patients data were collected prospectively and confirmed as axSpA were randomly divided into training (n = 143) and validation cohorts (n = 60). 1316 radiomics features were extracted from the 3.0T SIJ-MRI. A Nomogram model was constructed using multivariate logistic regression analysis Incorporating independent clinical factors and radiomics features score (Rad-score). The performance of clinics, Rad-score and nomogram models were evaluated by ROC analysis, calibration curve and decision curve analysis (DCA), and compared with the disease activity index(Ankylosing Spondylitis DAS (ASDAS)-C reactive protein (CRP), ASDAS-erythrocyte sedimentation rate (ESR), Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), Bath Ankylosing Spondylitis Functional Index (BASFI)) and Spondyloarthritis Research Consortium of Canada (SPARCC) MRI scoring system.ResultsThe Rad-score allowed a good discrimination in the training (AUC, 0.91; 95% CI, 0.85-0.96) and the validation cohort (AUC, 0.84; 95% CI, 0.73-0.96). The CRP-radiomics nomogram model also showed favorable discrimination in the training (AUC, 0.96; 95% CI, 0.93-0.99) and the validation cohort (AUC, 0.89; 95% CI, 0.80-0.98), better than BASDAI(AUC, 0.58), ASDAS-CRP(AUC, 0.72), ASDAS-ESR(AUC, 0.77), ESR(AUC, 0.72), CRP(AUC, 0.77) and BASFI(AUC, 0.73), had no statistical difference with SPARCC(AUC, 0.87). Calibration curves and DCA demonstrated the nomogram fit well (p > 0.05) and was useful for activity evaluation.ConclusionRad-score showed good discriminative ability to assess disease activity in axSpA. The nomogram can increase the efficacy for assessment axSpA disease activity, which might simplify clinical evaluation.Figure 1.Comparison of ROC curve analyses in prediction models.

Abstract
BackgroundBone marrow oedema (BMO) of the sacroiliac joints (SIJs) is evaluated to diagnose, classify and monitor disease activity in patients with axial spondyloarthritis (axSpA). Available quantitative methodologies rely on human visual assessment, and errors can’t be completely avoided. Radiomics can extract and select discriminative and quantified features from regions of interest (ROIs), making a more accurate and objective description of BMO.ObjectivesTo develop a more objective and efficient method based on radiomics to evaluate BMO of the SIJs by magnetic resonance imaging (MRI) in patients with axSpA in comparison with Spondyloarthritis Research Consortium of Canada (SPARCC) scoring system.MethodsFrom September 2013 to July 2021, 523 patients with axSpA underwent 3.0T SIJ-MRI were included, who were randomly classified as training cohort(n=367) and validation cohort(n=156). The optimal radiomics features, selected from the 3.0T SIJ-MRI in the training cohort, were included to build the radiomics model. Four clinical risk predictors were adopted to build the clinical model. The performance of the clinical and radiomics models was evaluated by ROC analysis and decision curve analysis (DCA). Rad-scores were calculated by the radiomics model and SPARCC scores were performed to quantify the BMO of SIJs. We also assessed the correlation between Rad-score and SPARCC score.ResultsThe radiomics model, built by 15 optimal features, showed favorable discrimination about SPARCC score <2 or ≥2 both in the training (AUC, 0.91; 95% CI: 0.88-0.94) and the validation cohort (AUC, 0.89; 95% CI, 0.84-0.94). DCA confirmed that the radiomics model was clinically useful. Furthermore, Rad-score has significant correlation with SPARCC score for scoring the status of BMO (rs=0.78, P< 0.001), and moderation correlation for scoring the change (r=0.40, P=0.005).ConclusionThe radiomics can accurately assess the BMO of the SIJs in axSpA, providing an alternative to SPARCC scoring system. There was a positive correlation between Rad-score and SPARCC score.References[1]van der Heijde D, Sieper J, Maksymowych WP, Lambert RG, Chen S, Hojnik M, et al.

Abstract
Transferrins are multifunctional proteins, but their role in the interaction of rice and brown planthopper (BPH) remains unclear. In this study, the full-length cDNA of transferrin genes NlTsf1, NlTsf2, and NlTsf3 was cloned. Reverse transcription quantitative polymerase chain reaction showed that the expressions of NlTsf1 and NlTsf3 were significantly suppressed in BPH reared on the resistant rice R1 by 68.0 and 86.7%, respectively, compared with that on the susceptible S9. The survival rate decreased to 3.3% for dsNlTsf3-treated nymphs, to 58.9% for dsNlTsf1, and to 56.7% for dsNlTsf2 on day 11. RNAi of NlTsf3 against females largely reduced the number of eggs by 99.4%, and it decreased by 48.6% for dsNlTsf1 but did not significantly decrease for dsNlTsf2. Collectively, NlTsf1, NlTsf2, and NlTsf3 are essential for the survival and fecundity of BPH and are differentially involved in the interaction between rice and BPH. Therefore, NlTsf1 and NlTsf3 may be used as targets to control BPH.

Abstract
BACKGROUND Urethrocutaneous fistula is one of the most common complications arising from hypospadias surgery. The purpose of our study was to investigate the effectiveness and safety of allogeneic human acellular dermal matrix (HADM) application as a means of preventing the occurrence of urethrocutaneous fistula following hypospadias surgery. METHODS This is a non-randomized study of 219 cases (out of 270 patients with hypospadias) which satisfied inclusion and exclusion criteria. These patients were divided into two groups: 101 HADM patients, and 118 control patients (who did not receive HADM). In the control group, 77 boys were treated by single-stage urethroplasty (TIP) and 41 underwent staged urethroplasty (Thiersch-Duplay). In the HADM group, 59 boys underwent the TIP and 42 underwent the Thiersch-Duplay. In the postoperative period, we recorded the incidence of infection, urethrocutaneous fistula, and urethral stricture complications in these two groups of patients. The effectiveness and safety of HADM in preventing urethrocutaneous fistula following hypospadias surgery were evaluated according to these indicators. RESULTS In the control group, following the operation there were 16 cases of infection, 38 cases of urethrocutaneous fistula after extubating, and 5 cases of urethral stricture. In the HADM group, there were 19 cases of postoperative infection, 12 cases of urethrocutaneous fistula after extubating, and 5 children with urethral stricture. In comparing the two groups, it was found that the postoperative infection rate (13.6 vs. 18.8%) and the incidence of urethral stricture (4.2 vs. 5.0%) were not statistically significant (P > 0.05), while the postoperative urethrocutaneous fistula rate (32.2 vs. 11.9%) was statistically significant (P < 0.001). CONCLUSION It is found that HADM application can significantly reduce the incidence of urethrocutaneous fistula complications, without increasing the risk of infection and urethral stricture.

Abstract
OBJECTIVES Cognitive impairment commonly occurs among older people worldwide. Although the Mediterranean-DASH Intervention for Neurodegenerative Delay (MIND) diet was associated with better cognitive function and lower risk of cognitive impairment, it could not be applied to older Chinese due to the traditional dietary characteristics in China. We aimed to develop the Chinese version of the MIND (cMIND) diet and verify its association with cognitive impairment among older Chinese individuals. DESIGN A cross-sectional study. SETTING AND PARTICIPANTS We included a total of 11,245 participants from the Chinese Longitudinal Healthy Longevity Study (CLHLS) follow-up survey in 2018. The mean age of the participants at study baseline was 84.06 (±11.46) years. MEASUREMENTS We established the cMIND diet based on current evidence in the diet-cognition field, combined with Chinese dietary characteristics. The verification of its association with cognitive impairment was conducted using the data from the CLHLS follow-up survey. Adherence to the cMIND diet was assessed by the cMIND diet score, which was calculated from a food frequency questionnaire. Cognitive impairment was identified by the Mini-Mental State Examination. Instrumental activities of daily living (IADL) disability was defined according to the self-reported performance of eight activities. RESULTS The cMIND diet comprised 11 brain-healthy food groups and 1 unhealthy food group. The median cMIND diet score of all participants was 4.5 (from a total of 12 points) and the prevalence of cognitive impairment was 15.2%. Compared with the lowest tertile, the highest tertile score was associated with lower odds of cognitive impairment (odds ratio (OR)=0.60, 95% confidence interval (CI): 0.51-0.72) and IADL disability (OR=0.86, 95% CI: 0.75-0.98) in the full-adjusted model. CONCLUSION We developed the cMIND diet that was suitable for older Chinese individuals, and our results suggested that higher adherence to the cMIND diet was associated with reduced odds of cognitive impairment and IADL disability. In view of the limitations of cross-sectional design in the study, further research is clearly warranted.

Abstract
BACKGROUND Traditional endoscopic submucosal dissection (ESD) has developed different methods, such as pocket method (P-ESD), traction-assisted method (T-ESD), and hybrid method (H-ESD). In this meta-analysis, the benefits and drawbacks of different ESD methods were discussed and ranked. STUDY DESIGN Studies comparing different methods of colorectal ESD were searched by using PubMed, EMBASE, and Cochrane Library databases. The study was conducted for five endpoints: en bloc resection rate, R0 resection rate, operation time, dissection speed, and adverse events rate. Pairwise and network meta-analyses were performed through Rev Man 5.4 and Stata 16.0. The quality of all included studies was assessed using the Cochrane Risk of Bias Tool and the Newcastle-Ottawa Scale. RESULTS Twenty-six studies met the inclusion criteria, including 7 RCTs and 19 non-RCTs, with a total of 3,002 patients. The pooled analysis showed that the en bloc resection rate of H-ESD was significantly lower than that of C-ESD, P-ESD, and T-ESD (RR = 0.28, 95% CI [0.12, 0.65]; RR = 0.11, 95% CI [0.03, 0.44]; RR = 8.28, 95% CI [2.50, 27.42]). Compared with C-ESD, the operation time of H-ESD and T-ESD was significantly shorter (MD = -21.83, 95% CI [-34.76, -8.90]; MD = -23.8, 95% CI [-32.55, -15.06]). Meanwhile, the operation time of T-ESD was also significantly shorter than that of P-ESD (MD = -18.74, 95% CI [-31.93, -5.54]). The dissection speed of T-ESD was significantly faster than that of C-ESD (MD = 6.26, 95% CI [2.29, 10.23]). CONCLUSION P-ESD and T-ESD are probably the two best methods of colorectal ESD at present. The advantages of P-ESD are high en bloc resection rate and low incidence of adverse events. The advantages of T-ESD are rapid dissection and short operation time.

Abstract
Oxygen (O2 ) limitation contributes to persistence of large carbon (C) stocks in saturated soils. However, many soils experience spatiotemporal O2 fluctuations impacted by climate and land-use change, and O2 -mediated climate feedbacks from soil greenhouse gas emissions remain poorly constrained. Current theory and models posit that anoxia uniformly suppresses carbon (C) decomposition. Here we show that periodic anoxia may sustain or even stimulate decomposition over weeks to months in two disparate soils by increasing turnover and/or size of fast-cycling C pools relative to static oxic conditions, and by sustaining decomposition of reduced organic molecules. Cumulative C losses did not decrease consistently as cumulative O2 exposure decreased. After >1 year, soils anoxic for 75% of the time had similar C losses as the oxic control but nearly threefold greater climate impact on a CO2 -equivalent basis (20-year timescale) due to high methane (CH4 ) emission. A mechanistic model incorporating current theory closely reproduced oxic control results but systematically underestimated C losses under O2 fluctuations. Using a model-experiment integration (ModEx) approach, we found that models were improved by varying microbial maintenance respiration and the fraction of CH4 production in total C mineralization as a function of O2 availability. Consistent with thermodynamic expectations, the calibrated models predicted lower microbial C-use efficiency with increasing anoxic duration in one soil; in the other soil, dynamic organo-mineral interactions implied by our empirical data but not represented in the model may have obscured this relationship. In both soils, the updated model was better able to capture transient spikes in C mineralization that occurred following anoxic-oxic transitions, where decomposition from the fluctuating-O2 treatments greatly exceeded the control. Overall, our data-model comparison indicates that incorporating emergent biogeochemical properties of soil O2 variability will be critical for effectively modeling C-climate feedbacks in humid ecosystems.

Abstract
BACKGROUND The brown planthopper (BPH), Nilaparvata lugens, is a serious insect pest of rice. Autophagy and its related gene ATG3 play multiple roles in insects. However, information about the functions of ATG3 in BPH (NlATG3) is unavailable, and its potential as a target for pest control remains unclear. RESULTS RT-qPCR results showed a relatively low expression of NlATG3 in 1st-4th-instar nymphs, which increased through 9-day-old adults. The expression of NlATG3 increased continuously in 1-day-old through 5-day-old eggs, whereas it decreased thereafter. The mRNA level of NlATG3 was markedly higher in the ovary (1.16) and head (1.00) compared to the rest body parts of BPH adults. Injecting nymphs with dsNlATG3 at doses from 62.5 to 250 ng per insect had strong lethal effect upon them. For the 5th-instar nymphs, all individuals died within 5 days after receiving the dsNlATG3, and importantly, no individual successfully molted. Transmission electron microscopy revealed the new cuticle of nymphs injected with dsNlATG3 became loose and curved, which is clearly different from that of the control. Correspondingly, the obvious vesicles in epidermal cells disappeared after dsNlATG3-treatment. RNAi of NlATG3 significantly reduced the total number of eggs laid per female as well as the eggs' hatchability, especially in the dsNlATG3♀ × dsGFP♂ group, whose total number of eggs laid per female largely decreased by 80.4%, and whose eggs' hatchability was significantly reduced from 95.7% to zero, when compared with the control (dsGFP♀ × dsGFP♂). CONCLUSION NlATG3 is a promising target for developing RNAi-based insect management strategies. © 2021 Society of Chemical Industry.

Abstract
Objective: To describe the distribution and characteristics of peripheral anterior synechiae (PAS) in patients with primary angle-closure glaucoma (PACG). Methods: Retrospective case study. A total of 285 PACG patients (406 eyes) diagnosed in the Eye Hospital, School of Ophthalmology and Optometry, Wenzhou Medical University from January 2017 to August 2019 were included. They were 102 males and 183 females, with a median age of 67 years old (range, 21 to 95 years old). The PAS range was detected by gonioscopy examination, and the frequency distribution of PAS at 12 clock points was counted by clockwise. The PAS distribution at the middle point of PAS with continuous distribution and ≤6 clock points was assessed. Results: In all cases, PAS of the right eye was concentrated at 11:00 to 4:00 regions [range, 62.0% (129/208) to 78.8% (164/208)]. PAS of the left eye was concentrated at 7:00 to 1:00 regions [range, 50.0% (99/198) to 75.8% (150/198)]. When the PAS range of the atrial angle was ≤6 clock regions, it was mainly at 12:00 to 3:00 [range, 58.3% (74/127) to 67.7% (86/127)] in the right eye and at 10:00 to 12:00 [range, 54.8% (68/124) to 66.1% (82/124)] in the left eye. Among 121 cases (242 eyes) with both eyes involved, the PAS region was at 11:00 to 5:00 [range, 52.1% (63/121) to 79.3% (96/121)] in the right eye and at 8:00 to 1:00 [range, 50.4% (61/121) to 76.9% (93/121)] in the left eye. When the PAS range of the atrial angle was ≤6 clock regions, it was mainly at 12:00 to 4:00 [range, 53.2% (41/77) to 71.4% (55/77)] in the right eye and at 10:00 to 12:00 [range, 50.6% (39/77) to 64.9% (50/77)] in the left eye. In all cases, there were 171 cases of right eyes and 175 cases of left eyes with continuous angle PAS. The central PAS clock position of the right eye was mainly at 11:00 to 3:00 [range, 15.2% (26/171) to 24.0% (41/171)], and that of the left eye was mainly at 8:00 to 12:00 [range, 15.4% (27/175) to 20.6% (36/175)]. Among cases with both eyes involved, there were 98 cases of right eyes and 104 cases of left eyes with continuous angle PAS. The clock distribution of the middle position of the right eye angle PAS was concentrated at 11:00 to 3:00 [range, 17.3% (17/98) to 26.5% (26/98)], and that of the left eye was concentrated at 8:00 to 12:00 [range, 13.5% (14/104) to 20.2% (21/104)]. Conclusions: The PAS of PACG patients is mainly located in the upper and nasal sides, and the closer to the temporal side, the smaller the PAS frequency, showing a gradual downward trend. The PAS distribution of binocular angles is of obvious mirror symmetry. (Chin J Ophthalmol, 2021, 57: 666-671).

Abstract
This study aims to explore the mechanism of cyclic tensile stress (CTS) on human chondrocytes (CHs) relating to the reactive oxygen species (ROS) generation and extracellular matrix (ECM) stability in vitro. A well-established CTS model with 5%, 10%, or 20% elongation was performed for CHs stretching. After CTS, the cell viability, total ROS level, main ECM components, matrix metalloproteinase (MMP), tissue inhibitor of metalloproteinase (TIMP), F-actin density, and some anti-oxidative enzymes were analyzed. Additionally, the antioxidant N-acetylcysteine (NAC) and cytochalasin D were used to suppress the ROS production and F-actin polymerization when the CHs underwent CTS, respectively. The treatment of 20% elongation-CST significantly decreased the CH viability and the expressions of collagen II, aggrecan, anti-oxidative enzymes and TIMP3/4, however, it increased the ROS accumulation, F-actin polymerization, and the expression of collagen I and MMP3/13. In contrast, the application of NAC and cytochalasin D could partly rescue the CHs from the injury caused by the high CTS. Therefore, high CTS disrupts the ECM by remodeling the F-actin cytoskeleton and promoting ROS production. Cytochalasin D and NAC are effective in rejecting F-actin cytoskeleton polymerization, and ROS accumulation through a potential synergetic process, which alleviates the ECM injury caused by High CTS.

Abstract
Objective: To evaluate the quality of life of patients with primary open-angle glaucoma (POAG) and its related factors in Wenzhou. Methods: Cross-sectional analysis. A total of 339 POAG patients diagnosed in the Wenzhou glaucoma progression study conducted in the Eye Hospital, School of Ophthalmology and Optometry, Wenzhou Medical University from March 2014 to October 2019 were included. Quality of life of POAG patients was assessed by EQ-5D including the visual analogue scale (VAS). The effects of gender, age, visual field loss (VFL), family history of glaucoma, hypertension, diabetes, migraine, sleep quality, and amateur exercise on the quality of life were analyzed. The utility value (UV) and VAS score were expressed as the median (P25, P75), and Mann-Whitney U was used for the comparison between two groups. Kruskal-Wallis H was performed to compare the differences among multiple groups. Results: A total of 339 POAG patients were included in the study; 164 were males (48.4%), and 175 were females (51.6%). The mean age was (63±10) years. Thirty-four patients (10.0%) had received medication (including one with combined surgical treatment), while the remaining 305 patients (90.0%) had received no anti-glaucoma treatment. Among the patients, 10.5% (32/305) had no VFL, 68.9% (210/305) had mild VFL, 17.0% (52/305) had moderate VFL, and 3.6% (11/305) had severe VFL. In all patients, the median of UV was 1.000 (1.000, 1.000), the mean of UV was 0.964, and the median of VAS score was 80 (75, 90), the mean of VAS score was 81.58. Anxiety or depression and pain or discomfort occurred in 45.7% (43/94) and 34.1% (32/94), respectively, of POAG patients with decreased UVs, as well as mobility constraints in 13.8 % (13/94) and usual activity constraints in 6.4% (6/94). The median of UV of the eye with a better visual field in the group without VFL or with mild or moderate VFL was 1.000 (1.000, 1.000), and in the group with severe VFL was 1.000 (0.862, 1.000), but there was no significant difference in the UV and the VAS score of the eye with a better visual field among groups with different degrees of VFL (both P>0.05). There was statistically significant difference in the UV among groups with different sleep qualities (H=17.465; P<0.01). Using pairwise comparison, the median of UV of the very good sleep group was 1.000 (1.000, 1.000), significantly different to the slightly poor sleep group 1.000 (0.866, 1.000) (z=3.613; P<0.05). The median of UV in patients with migraine was 1.000 (0.875, 1.000), without migraine 1.000 (1.000, 1.000), and in patients with hypertension was 1.000 (0.875, 1.000), without hypertension 1.000 (1.000, 1.000), and in patients with diabetes was 1.000 (0.875, 1.000), without diabetes was 1.000 (1.000, 1.000), the difference was statistically significant (Z=-2.189, -3.864, -2.417; all P<0.05). The UV was not related to age, gender, family history of glaucoma, amateur exercise, alcohol and tobacco, and history of anti-glaucoma medication (all P>0.05). Conclusions: VFL is related to the UV of POAG patients in Wenzhou. Quality of life in mild POAG patients is good but decrease in advanced POAG patients. Sleep quality, systemic complications and physical or psychological discomfort impact on quality of life in POAG patients. (Chin J Ophthalmol, 2021, 57: 207-214).

Abstract
OBJECTIVE These were two folds: at first, to develop an automatic grading system specifically dedicated to some facial signs of men, similar to the one previously validated on women of different ethnic ancestry and second, to assess its potential in detecting and grading the possible impacts of a severe aerial urban pollution on some facial signs of Chinese men. METHODS In both studies, selfie images were obtained from differently aged men. Nine facial signs were automatically graded through a specific A.I-based algorithm and clinically assessed by a panel of experts and dermatologists. Selfie pictures were taken from individual smartphones of variable optical properties. The first study, designed for developing an automatic grading system, involved three comparable cohorts of men from three different regional ancestries (African, Asian, Caucasian, 110 each) the selfie images of which were acquired under four different lighting conditions. As a second use case study, the facial signs of two cohorts of Chinese men (101 and 100, each), differently aged, regularly exposed to very different aerial urban pollution conditions (UP) were analysed by the same algorithm, selfies being taken under only one lighting condition. RESULTS -The new automatic grading system of facial signs suits well to men, showing comparable results than that the one dedicated to women and provides data in close agreement with experts' assessments. -In both cases (expert's or automatic methodology), the accuracy of the scores appeared ethnic-dependent. -The applied case confirmed previous results obtained clinically, that is, that many facial signs were found of an increased severity among men exposed to a severe urban pollution, as compared to those living in a less polluted city. -In both studies, statistical agreements between the automatic grading system and expert's assessments were reached. In some facial signs, the automatic grading system seems offering a slightly better accuracy than the assessments made by the experts. CONCLUSION Apart from some minor limitations, this A.I-based automatic grading system, free from human intervention, performed as well as the one previously developed in women, in close agreement with expert's assessments. In epidemiological studies, this system offers an easy, fast, affordable and confidential approach in the detection and quantification of male facial signs.

Abstract
BACKGROUND We conducted a retrospective exploratory analysis to evaluate the effects of baseline tumour immune infiltrate on disease-free survival (DFS) outcomes in patients with fully resected stage IIC-IIIC melanoma receiving adjuvant vemurafenib monotherapy or placebo in the BRIM8 study. PATIENTS AND METHODS BRIM8 was a phase III, international, double-blind, randomised, placebo-controlled study. Eligible patients with BRAFV600 mutation-positive, completely resected melanoma were randomly assigned to oral vemurafenib (960 mg twice daily) or matching placebo for 52 weeks. The primary end point was DFS. The association of CD8+ T-cell infiltration and programmed death ligand 1 (PD-L1) expression with DFS, as measured by immunohistochemistry, was explored retrospectively. RESULTS Four hundred ninety-eight patients were randomly assigned to receive adjuvant vemurafenib (n = 250) or placebo (n = 248); tumour samples were available for biomarker analysis for approximately 60% of patients. In the pooled biomarker population, placebo-treated patients with <1% CD8+ T cells in the tumour centre had shorter median DFS than those with ≥1% CD8+ T cells (7.7 versus 47.8 months). DFS benefit from vemurafenib versus placebo was greater in patients with <1% CD8+ T cells [hazard ratio (HR) 0.56; 95% confidence interval (CI) 0.34-0.92) than in patients with ≥1% CD8+ T cells (HR 0.77; 95% CI 0.48-1.22). Likewise, median DFS was shorter among placebo-treated patients with <5% versus ≥5% PD-L1+ immune cells (IC) in the tumour (7.2 versus 47.8 months). A greater DFS benefit with vemurafenib versus placebo was observed in patients with <5% PD-L1+IC (HR 0.36; 95% CI 0.24-0.56) than in patients with ≥5% PD-L1+IC (HR 0.99; 95% CI 0.58-1.69). CONCLUSIONS The presence of CD8+ T cells and PD-L1+IC are favourable prognostic factors for DFS. Treatment with adjuvant vemurafenib may overcome the poor DFS prognosis associated with low CD8+ T-cell count or PD-L1 expression. CLINICALTRIALS. GOV IDENTIFIER NCT01667419.

Abstract
Osteoarthritis (OA) is marked by transcriptional factors. Twist-related protein 1 (TWIST-1) leads to the down-regulation of functional transcriptional regulators such as transforming growth factor-beta 1 (TGF-β1) and Wnt signals, thus blocking the growth and maturation of chondrocytes and providing new pathways to the production of therapeutic targets in OA therapy. Our research assesses the role of aberrant expressions TWIST1 and TGF-β1 as therapeutic targets in the regulation of osteoarthritis by treating with piperlongumine, a known biological agent. Monosodium iodoacetate (MIA) was administered to 32 male Wistar rats into their knee joints to provoke osteoarthritis. A week later, piperlongumine (PL) was orally administered to these rats for a duration of 28 days. The radiographic photos of these rats were documented. The histopathological and serum factors, namely interleukin-1beta (IL-1β), matrix metaloproteinases MMP-1 and MMP-3, were evaluated and their respective results were reported. RNA was extracted and real-time-PCR technique was optimized for TWIST1, TGF-1β and glyceraldehyde 3-phosphate dehydrogenase (GAPDH) determination and sample values were recorded. When treated with PL at 100 mg/kg, our radiographic and histological studies revealed a substantial reduction of OA in rat models but no major improvements were observed at PL 50 mg/kg. Serum levels of IL-1β, MMP-1, and MMP-3 were greatly decreased when treated with PL 100 mg/kg. When administered with a dose higher than PL-100 mg/kg, the relative expressions of TWIST1, mRNA and TGF-β1 mRNA proteins were drastically reduced. Our results suggested that high-dose treatment with piperlongumine was beneficial and effective. TWIST1 and TGF-β1 aberrant expressions contributed as a new transcription factor function and supported the reduction of osteoarthritis intensity with piperlongumine therapy.

Abstract
Osteoporosis is a chronic disease of low bone mass and fragility. Treatment is frequently compromised by suboptimal medication compliance causing increased morbidity. This review investigates adherence and persistence to parenteral osteoporosis therapies. Findings reveal parenteral medications requiring reduced dosing frequency have higher compliance than oral therapies. This systematic review examines real-world adherence to parenteral osteoporosis therapies. We searched PubMed, Medline, and EMBASE databases for English language observational studies that examined patient adherence and/or persistence to parenteral osteoporosis treatments (teriparatide sc, ibandronate iv, zoledronic acid iv, and denosumab sc) in adults with osteoporosis published up to September 2018. Studies with only self-reported adherence or persistence data and those with less than 20 patients were excluded. Quality assessment of included studies was completed using the Newcastle-Ottawa quality assessment scale (NOS). We identified 40 eligible studies. Teriparatide was examined in 29 studies, with persistence rates of 10-87% (median 55%) at 1 year and 10-69% (median 29.5%) at 2 years, and adherence rates of 21-89% (median 53%) at 1 year and 37-68% (median 40%) at 2 years. Ten studies of zoledronic acid reported persistence rates of 34-73% (median 42%) for second dose and 20-54% (median 35.8%) for third dose. Ten studies of ibandronate adherence reported and 2-year persistence rates of 31-58% (median 47.5%) in 1 year and 13-35% (median 25%) at 2 years, and adherence rates of 21-72% (median 47.3%) and 15-58% (median 36.5%) respectively. Denosumab was reported in 19 studies, with second (1 year) and fourth (2 year) dose persistence rates of 61-100% (median 81%) and 36-99% (median 45.5%). There is substantial heterogeneity in reports of persistence and adherence rates with parenteral osteoporosis therapies. Most of the published data are from short-term studies and evaluations of long-term adherence and persistence with parenteral therapies for osteoporosis are needed.

Abstract
The ongoing global change is multi-faceted, but the interactive effects of multiple drivers on the persistence of soil carbon (C) are poorly understood. We examined the effects of warming, reactive nitrogen (N) inputs (12 g N m-2 year-1 ) and altered precipitation (+ or - 30% ambient) on soil aggregates and mineral-associated C in a 4 year manipulation experiment with a semi-arid grassland on China's Loess Plateau. Our results showed that in the absence of N inputs, precipitation additions significantly enhanced soil aggregation and promoted the coupling between aggregation and both soil fungal biomass and exchangeable Mg2+ . However, N inputs negated the promotional effects of increased precipitation, mainly through suppressing fungal growth and altering soil pH and clay-Mg2+ -OC bridging. Warming increased C content in the mineral-associated fraction, likely by increasing inputs of root-derived C, and reducing turnover of existing mineral-associated C due to suppression of fungal growth and soil respiration. Together, our results provide new insights into the potential mechanisms through which multiple global change factors control soil C persistence in arid and semi-arid grasslands. These findings suggest that the interactive effects among global change factors should be incorporated to predict the soil C dynamics under future global change scenarios.

Abstract
OBJECTIVE To determine the respective weights of certain facial signs on the assessment of perceived age, tired-look and healthy glow on Chinese men of different ages. MATERIAL AND METHODS Photographs were taken of the faces of 420 Chinese men of different ages, under standardized conditions. These photographs allowed to focus and define 15 facial signs, which were then graded by 15 experts and dermatologists, using standardized scales provided by a reference Skin Aging Atlas. The facial signs were dispatched into 5 clusters, namely wrinkles/texture, ptosis/sagging, pigmentation disorders, vascular disorders and cheek skin pores. A naïve panel, composed of 80 Chinese women, of similar age range were asked, when viewing full-face photographs, to: (i) attribute on a 0-10 scale their perception of both the tired-look and healthy glow aspects and (ii) estimate the age of the subject. RESULTS With the exception of vascular disorders, the severity of all 4 clusters increased with age, although at different rates. The ptosis/sagging or pigmentation disorders showed a rather regular progression. Although perceived ages and real ages were found to be closely correlated, the vast majority of subjects were judged older by 2-10 years. The changes in facial signs (and their related clusters) were significantly correlated with perceived age, with the exceptions of skin spot density and cheek skin pores. Although the aspects of tired-look and healthy glow were logically found to be anti-correlated, tired-look was more statistically associated with perceived age for the five clusters. Signs of eye contour appear to be closely correlated with the perception of a tired-look. CONCLUSION Within facial clinical clusters, wrinkles/texture and ptosis/sagging are major factors in the assessment of perceived age in Chinese men. Tired-look appears to be strongly associated with perceived age.

Abstract
Objective: To investigate the effect of intestinal preparation on the efficacy and complications of fecal microbiota transplantation (FMT). Methods: A retrospective cohort study was performed. Clinical and follow-up data of 1501 patients who received FMT in the department of Colorectal Disease Specialty, Intestinal Microecology Diagnosis and Treatment Center, the Tenth People's Hospital, Tongji University from February 2018 to June 2019 were collected retrospectively. According to the intestinal preparation before FMT treatment, patients were divided into non-intestinal preparation group (n=216), antibiotic pretreatment group (n=383), intestinal cleansing group (n=267), and antibiotic combined with intestinal cleansing group (n=635). The adverse reactions after FMT treatment and the effective rates at 4-week and 8-week after treatment among the groups were compared. Patients, who repeated FMT treatment in the 3rd month and the 6th month due to reduced efficacy or ineffectiveness were divided into two subgroups: without intestinal preparation group and with intestinal preparation group. The effective rates of the two subgroups were compared. Results: Of the 1501 cases, 588 were male and 913 were female with mean age of (43.3±13.7) years and body mass index of (20.2±2.1) kg/m(2). Transplantation course was (3.3±1.7) weeks. The underlying diseases mainly included constipation (n=564), Crohn's disease (n=157), ulcerative colitis (n=142), irritable bowel syndrome (n=158), recurrent C. difficile infection (CDI) (n=106), autism (n=84), radiation intestinal injury (n=133), radiation enteritis (n=133), and non-CDI chronic diarrhea (n=60); the remaining cases (n=155). Baseline data among the 4 groups were not significantly different (all P>0.05). The overall morbidity of complication was 31.1% (467/1501), including 41 cases of vomiting (2.7%), 91 of nausea (6.1%), 49 of diarrhea (3.3%), 41 of abdominal pain (2.7%), 79 of bloating (5.3%), 72 of throat pain (4.8%), 38 of dizziness (2.5%), 51 of fever (3.4%), 3 of pulmonary infection (0.2%) and 2 of intestinal infection (0.1%). The above symptoms disappeared after symptomatic treatment. There was no statistically significant difference in the incidence of adverse reactions among the 4 groups (P>0.05). After 4-week of FMT treatment, the overall effective rate was 63.5% (902/1420); the effective rate of non-intestinal preparation group, antibiotic pretreatment group, intestinal cleaning group, and antibiotic combined with intestinal cleansing groupwas 57.6% (114/198), 64.2% (231/360), 60.2% (154/265) and 66.5% (403/606), respectively, with no statistically significant difference (χ(2)=6.659, P=0.084). After 8-week of FMT treatment, the overall effective rate was 61.3% (729/1293); the effective rate of non-intestinal preparation group, antibiotic pretreatment group, intestinal cleaning group, and antibiotic combined with intestinal cleansing group was 54.0% (88/163), 62.2% (202/325), 57.4% (132/230) and 64.4% (370/575), respectively, with no statistically significant difference (χ(2)=13.620, P=0.003). The effective rates of antibiotic combined with intestinal cleansing group and antibiotic pretreatment group were obviously higher than that of non-intestinal preparation group (χ(2)=5.789, P=0.016; χ(2)=10.117, P=0.001). Subgroup analysis showed that in the third month, the effective rate at 4-week after treatment was 60.1% (184/306) in the without intestinal preparation group and 61.5% (115/187) in the with intestinal preparation group, whose difference was not significant (χ(2)=0.091, P=0.763); however, in the sixth month, the effective rate at 4-week after treatment was 51.4% (89/173) in the without intestinal preparation group and 61.2% (161/263) in the with intestinal preparationgroup, whose difference was significant (χ(2)=4.229, P=0.040). Conclusions: FMT treatment is safe and effective. The combination of antibiotics and intestinal cleaning can improve overall efficacy of FMT. For patients who need repeated FMT treatment, the combination of antibiotics and intestinal cleaning program within 3 months has no significant effect on the effective rate, but in the sixth month, combinedpreparation is necessary.

Abstract
Objective: To examine the association between the clinical efficacy of fecal microbiota transplantation (FMT) in recipients and the choice of donor, and to observe the characteristics of intestinal flora and metabolites among different donors. Methods: A retrospective case-control study was conducted. Donor whose feces was administrated for more than 30 recipients was enrolled. Data of 20 FMT donors and corresponding recipients at Intestinal Microecology Diagnosis and Treatment Center of the Tenth People's Hospital from October 2018 to December 2019 were collected retrospectively. During follow-up, the efficacy of each recipient 8-week after FMT treatment was recorded and analyzed. Based on the efficacy of each donor, the donors were divided into three groups: high efficacy group (effective rate >60%, 10 donors), moderate efficacy group (effective rate 30%-60%, 6 donors) and low efficacy group (effective rate <30%, 4 donors). The structure of the bacterial flora and the content of fecal short-chain fatty acids in each group of donors were detected and compared among groups. Association of the efficacy of each donor group with the morbidity of complications, and association of efficacy of recipients with donors were analyzed. The evaluation indicators of FMT efficacy included objective clinical effectiveness and/or subjective effectiveness. Objective effectiveness indicated clinical cure plus clinical improvement, and subjective effectiveness indicated marked effectiveness plus medium effectiveness through questionnaire during follow-up. Results: A total of 1387 recipients were treated by 20 donors, including 749 cases of chronic constipation, 141 cases of chronic diarrhea, 107 cases of inflammatory bowel disease (IBD), 121 cases of irritable bowel syndrome (IBS), 83 cases of autism, and 186 cases of other diseases, such as radiation bowel injury, intestinal pseudo-obstruction, paralytic intestinal obstruction, functional bloating and allergic diseases. There were 829 cases, 403 cases, and 155 cases in high efficacy group, moderate efficacy group and low efficacy group respectively. Baseline data among 3 groups were not significantly different (all P> 0.05). In comparison of bacterial abundance (operational taxonomic unit, OTU) among different effective donor groups, the high efficacy group was the highest (330.68±57.28), the moderate efficacy group was the second (237.79±41.89), and the low efficacy group was the lowest (160.60±49.61), whose difference was statistically significant (F=16.910, P<0.001). In comparison of bacterial diversity (Shannon index), the high efficacy group and the moderate efficacy group were higher (2.96±0.36 and 2.67±0.54, respectively), and the low efficacy group was lower (2.09±0.55), whose difference was statistically significant (F=5.255, P=0.017). In comparison of butyric acid content among three groups, the high efficacy group had the highest [(59.20±9.00) μmol/g], followed by middle efficacy group [(46.92±9.48) μmol/g], and the low efficacy group had the lowest [(37.23±5.03) μmol/g], whose difference was statistically significant (F=10.383, P=0.001). The differences of acetic acid and propionic acid among three groups were not statistically significant (all P>0.05). A total of 418 cases developed complications (30.1%). Morbidity of complication in low efficacy group, moderate efficacy group and high efficacy group was 40.6% (63/155), 30.0% (121/403) and 28.2% (243/829) respectively, and the difference was statistically significant (χ(2)=9.568, P=0.008). The incidence of diarrhea in low efficacy group, moderate efficacy group and high efficacy group was 7.1% (11/155), 4.0% (16/403) and 2.8% (23/829) respectively, and the difference was statistically significant (χ(2)=7.239, P=0.027). Comparing the incidences of other types of complications, no statistically significant differences were found (all P>0.05). Follow up began 8 weeks after the FMT treatment. The total follow-up rate was 83.6% (1160/1387). The overall effective rate 58.3% (676/1160). Effective rates of various diseases were as follows: chronic constipation 54.3% (328/604), chronic diarrhea 88.5% (115/130), IBD 56.1% (55/98), IBS 55.1% (59/107), autism 61.6% (45/73), and other diseases 50.0% (74/148). Comparing the effective rate of three groups of donors for different diseases, there was no statistically significant difference in chronic diarrhea (P>0.05); there was a positive correlation trend in IBD, IBS and autism, but the differences were not statistically significant (all P>0.05). For chronic constipation and other diseases, high efficacy group had the highest effective rate [65.0% (243/374) and 63.2% (55/87)], followed by moderate efficacy group [49.4% (86/174) and 38.1% (16/42)], and low efficacy group had the lowest [16.1% (9/56) and 15.8% (3/19)], whose differences were significant (all P<0.05). Conclusions: Different donors have different efficacy in different diseases. Chronic constipation, radiation bowel injury, etc. need to choose donors with high efficacy. IBD, IBS and autism may also be related to the effectiveness of donors, while chronic diarrhea is not associated to the donor. The efficiency of the donor is negatively correlated to the morbidity of complications. The abundance and diversity of intestinal flora and the content of butyric acid may affect the efficacy of the donor.

Abstract
Colorectal surgery patients have severe intestinal flora disorders and antibiotic resistant bacteria due to the disease itself and preoperative treatment, as well as the influence of dietary structure and environmental factors. Perioperative anesthesia and operative stress can cause gastrointestinal motility disorders. In addition, the widespread use of prophylactic broad-spectrum antibiotics and antiacids aggravate intestinal flora disorders and induces severe postoperative infectious diarrhea, such as pseudomembranous enteritis and fatal enteritis. The clinical manifectation are severe infectious diarrhea with high fever and abdominal distension after surgery. The disease progresses rapidly. When the diagnosis and treatment are delayed, the patient can quickly develop shock and other serious complications such as anastomotic leakage, even die of multiple organ failure. Therefore, early diagnosis and treatment are crucial.

Abstract
Oxygen (O2 ) limitation is generally understood to suppress oil carbon (C) decomposition and is a key mechanism impacting terrestrial C stocks under global change. Yet, O2 limitation may differentially impact kinetic or thermodynamic versus physicochemical C protection mechanisms, challenging our understanding of how soil C may respond to climate-mediated changes in O2 dynamics. Although O2 limitation may suppress decomposition of new litter C inputs, release of physicochemically protected C due to iron (Fe) reduction could potentially sustain soil C losses. To test this trade-off, we incubated two disparate upland soils that experience periodic O2 limitation-a tropical rainforest Oxisol and a temperate cropland Mollisol-with added litter under either aerobic (control) or anaerobic conditions for 1 year. Anoxia suppressed total C loss by 27% in the Oxisol and by 41% in the Mollisol relative to the control, mainly due to the decrease in litter-C decomposition. However, anoxia sustained or even increased decomposition of native soil-C (11.0% vs. 12.4% in the control for the Oxisol and 12.5% vs. 5.3% in the control for the Mollisol, in terms of initial soil C mass), and it stimulated losses of metal- or mineral-associated C. Solid-state 13 C nuclear magnetic resonance spectroscopy demonstrated that anaerobic conditions decreased protein-derived C but increased lignin- and carbohydrate-C relative to the control. Our results indicate a trade-off between physicochemical and kinetic/thermodynamic C protection mechanisms under anaerobic conditions, whereby decreased decomposition of litter C was compensated by more extensive loss of mineral-associated soil C in both soils. This challenges the common assumption that anoxia inherently protects soil C and illustrates the vulnerability of mineral-associated C under anaerobic events characteristic of a warmer and wetter future climate.

Abstract
OBJECTIVE To explore some morphological features of the eyebrows of women of different ethnicities and ages. MATERIALS AND METHODS Standard digital photographs of 3600 women of six ethnicities, aged 18-84 years, previously used to describe the morphology of the human eyes, allowed us to focus on their eyebrows, as supplementary and opportunistic study. Photographs of both eyebrows were analysed partly by manual markings and automatically by dedicated algorithms. Six parameters of the eyebrows were recorded: length, waviness/curvature, oblique aspect, size (vertical height), total surface and hair coverage (density). RESULTS Most criteria present ethnic specificities. These are: length (longer eyebrows of Indian, shorter among African women); waviness where the straighter eyebrows were found among Chinese and Japanese women. In general, the longer the eyebrows, the higher their waviness and vice versa. Thickness (or height) of the eyebrows presents a wide ethnic variability as well as hair coverage, where African women present the lower hair density, inversely to Indian women. The same holds true with regard to the total surface of eyebrows, of a large variability (by about four times). Some criteria appear more individually dependent than ethnic-specific, such as the oblique positioning, at the exception of Indian women with less oblique eyebrows. In all subjects, the criteria of both eyebrows (Left vs. Right) were found to be highly correlated (r > 0.7, P < 0.001). CONCLUSION The present investigation brings new findings on a scarcely studied facial element, the morphologic features of which are, for most, ethnic-dependent. As applied consequences, the results of the present work pave the road to better adapt adorning procedures of the eyebrows vis-à-vis ethnic and age specificities.

Abstract
OBJECTIVE To assess the impact of an aerial chronic urban pollution (UP) on the severities of some facial signs of Chinese men living in two close but differently polluted Chinese cities. MATERIALS AND METHODS Standardized digital photographs were taken on 201 subjects from two cohorts of Chinese men (100 inhabitants of Baoding/very polluted and 101 inhabitants of Dalian/less polluted) differently aged (20-60 years) allowing a focus on 17 different facial signs. The latter were graded by 15 experts, using a clinical referential skin atlas. A questionnaire was filled by all subjects collecting their habits and uses with regard sun-exposures and skincare products. A naïve panel of 80 Chinese women, of comparable ages, attributed a perceived age to each subject under blind conditions. RESULTS These confirm previous data obtained on Chinese women, with a similar protocol, i.e. that some facial signs show an increased severity in the more polluted city. However, changes in facial signs, with age, are of a different pattern according to gender. In Chinese men, most signs show early onsets with however low age-related changes, inversely to those observed in women, at the exception of vascular disorders. Habits of sun-exposures and uses of skincare product were found totally similar in both cohorts, reinforcing the specific role of UP in the progressive changes of facial signs. Similar to the results previously obtained on Chinese women, men living in a more polluted city were judged older than those living in a less polluted aerial environment. CONCLUSION The present work confirms that a more severe UP increases the severities of some facial signs in Chinese men.

Abstract
From December 2019, Coronavirus disease 2019 (COVID-19) pneumonia (formerly known as the 2019 novel Coronavirus [2019-nCoV]) broke out in Wuhan, China. In this study, we present serial CT findings in a 40-year-old female patient with COVID-19 pneumonia who presented with the symptoms of fever, chest tightness, and fatigue. She was diagnosed with COVID-19 infection confirmed by real-time reverse-transcriptase-polymerase chain reaction. CT showed rapidly progressing peripheral consolidations and ground-glass opacities in both lungs. After treatment, the lesions were shown to be almost absorbed leaving the fibrous lesions.

Abstract
Autophagy plays multiple roles in regulating various physiological processes in cells. However, we currently lack a systematic analysis of autophagy and the autophagy-related gene 1 ATG1 in the brown planthopper (BPH, Nilaparvata lugens), one of the most destructive of the insect pests of rice. In this study, the full-length cDNA of an autophagy-related gene, NlATG1, was cloned from BPH. Real-time qPCR (RT-qPCR) revealed that this NlATG1 gene was expressed differently across developmental stages, at higher levels in nymphs but lower levels in adults. RNA interference with dsNlATG1 significantly decreased the mRNA level of the target gene to 14.6% at day 4 compared with that of the dsGFP control group. The survival of the dsNlATG1-treated group decreased significantly from day 4 onward, dropping to 48.3% on day 8. Examination using transmission electron microscopy (TEM) showed that epithelial cells of the BPH’s midgut in the dsNlATG1-treated group had less autophagic vacuoles than did the dsGFP control, and knockdown of NlATG1 clearly inhibited the starvation-induced autophagy response in this insect. RNA interference of NlATG1 upregulated the NlFis1 gene involved in mitochondrial fission, leading to reductions in mitochondrial width and area. Furthermore, knockdown of NlATG1 also decreased the ATP content and accumulation of glycogen. Together, these results demonstrate that the NlATG1 gene participates in regulating autophagy and fission of mitochondria in the brown planthopper, making it a potentially promising target for pest control given its key role in autophagy, including maintaining the normal structure and function of mitochondria.

Abstract
In recent years, with the improvement of high-intensity focused ultrasound technology, ultrasound cycloplasty has once again gained clinical recognition, becoming one of the non-invasive procedures for glaucoma treatment. Although high-level evidence is still lacking so far, the existing literature has shown that ultrasound cycloplasty can effectively and safely decreases the intraocular pressure in glaucoma by reducing the formation of aqueous humor and increasing the drainage of aqueous humor through the uveoscleral pathway. This article focuses on the efficacy and safety of ultrasound cycloplasty in the treatment of glaucoma, reviews the existing literature, and summarizes the information on the development of equipment, treatment mechanisms, surgical procedures, effectiveness of intraocular pressure reduction, and post-operative complications, with the purpose to provide reference for clinical research and application.
