Abstract
OBJECTIVES The association between blood pressure and frailty outcome in the middle-aged and older population remains controversial. This study aimed to examine the relationship between trajectories of systolic blood pressure (SBP) and new-onset frailty. DESIGN Cohort study with a 7-year follow-up. SETTING AND PARTICIPANTS Data were derived from 4 waves (2011, 2013, 2015 and 2018) of the China Health and Retirement Longitudinal Study and 6168 participants aged ≥45 years were included in the study. METHODS The frailty index (FI) was constructed based on 40 scored items, with FI ≥ 0.25 defined as frailty. We identified the 5-year trajectory of SBP by latent class trajectory modeling. The association between SBP trajectories and frailty was explored based on hazard ratios (HR) by four Cox proportional hazards models. Furthermore, we also investigated the relationship between mean SBP and systolic blood pressure variability (SBPV) and frailty. RESULTS 6168 participants were included in this study with a mean age of 59 years. We identified five trajectories based on SBP, which are maintained low-stable SBP (T0), moderate-stable SBP (T1), remitting then increasing SBP (T2), increasing then remitting SBP (T3), and remaining stable at high SBP levels (T4). During the 7-year follow-up period, frailty outcome occurred in 1415 participants. After adjusting for other confounders, the two trajectories labeled "T2" and "T4" were associated with a higher risk of frailty compared with T0. In addition, elevated SBP and increased SBPV were associated with risk of frailty. CONCLUSIONS Higher risk of frailty occurred in two trajectories, remitting then increasing and remaining stable at high SBP levels, were associated with a relatively higher risk of frailty.

Abstract
Endocrine therapy is the primary systemic therapy for hormone receptor-positive breast cancer, which runs through the whole process of treatment for early and metastatic breast cancer. The development of new endocrine agents and targeted drugs such as cyclin-dependent kinases 4/6(CDK4/6)inhibitors has improved outcome of patients with hormone receptor-positive breast cancer and changed the treatment landscape. The update of clinical research data provides more treatment options, calling for treatment optimization. Experts had a deep discussion around the hot topics on endocrine therapy of breast cancer, and formulated the'Expert consensus on endocrine therapy of breast cancer (2023 edition)'.This consensus is based on research data worldwide and clinical practice experience, with the aims of standardizing clinical diagnosis and optimizing treatment in neoadjuvant, adjuvant and metastatic setting of hormone receptor-positive breast cancer.

Abstract
Treatment of irritable bowel syndrome (IBS) remains challenging for clinicians. Probiotic fungi may act as candidate options for IBS treatment, but systematic evaluation of their clinical value remains scarce. This study is aimed to assess the efficacy and the safety of probiotic fungi for IBS treatment by means of systematic review and meta-analysis. PubMed, Embase, Web of Science, and the Cochrane Library, were searched up to June 2022. Randomised controlled trials recruited subjects with prescriptions of probiotic fungi were eligible. Efficacy and safety of probiotic fungi were re-evaluated. Continuous data were pooled to obtain standardised difference in means (SMD) with a 95% confidence interval. The search strategy identified 120 articles of which 7 trial assessing 883 subjects were included in the analysis. Systematic data support that Saccharomyces helps to relieve abdominal pain/discomfort (SMD = -0.205, P = 0.005), and presented potential improvements on psychological outcomes, stool form for IBS patients. It is hard to demonstrate favourable effects on other symptoms (including distension, mucus passage, sense of incomplete evacuation, urgency, straining). The incidence of mild complications ranged from 0 to 51.4%, but no serious complications were observed in the included trials. Therefore, the partial response and the relative safe of probiotic fungi for IBS treatment have been demonstrated from the existing trials. However, it is premature to eventually declare the practical effects of probiotic fungi. Conducting more high-quality and large-scale trials and real-world studies, or even developing new fungal strains, is still necessary.

Abstract
Objective: To investigate the clinicopathological features, immunophenotype and prognosis of nuclear protein in testis (NUT) midline carcinoma. Methods: Twenty-four resection cases of NUT midline carcinoma diagnosed at the Department of Pathology, Cancer Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College, Beijing, China from January 2018 to September 2022, were collected, and retrospectively analyzed for their clinicopathological characteristics. Relevant literature was reviewed. Results: All 24 cases of NUT midline carcinoma occurred in the chest or head and neck, including 14 men and 10 women, with a median age of 40 years. Histological examination showed that the tumors were poorly differentiated, with solid nested or sheet-like arrangement, small to medium-sized cells, sparse cytoplasm and coarse granular chromatin, including 5 cases with abrupt squamous epithelial differentiation. Immunohistochemistry showed that all 24 cases were positive for NUT protein, while 16 cases were p63 positive, 19 cases were p40 positive, 15 out of 18 cases were CK5/6 positive. Follow-up data were obtained for 21 patients (follow-up time range, 1-21 months), of which 11 survived, 10 died, and 3 were lost to follow-up. Conclusions: NUT midline carcinoma is a rare and highly aggressive malignancy with unique histological, immunophenotypic and molecular features. It has a poor prognosis.

Abstract
Objective: To investigate the regulatory effects of bio-intensity electric field on directional migration and microtubule acetylation in human epidermal cell line HaCaT, aiming to provide molecular theoretical basis for the clinical treatment of wound repair. Methods: The experimental research methods were used. HaCaT cells were collected and divided into simulated electric field group (n=54) placed in the electric field device without electricity for 3 h and electric field treatment group (n=52) treated with 200 mV/mm electric field for 3 h (the same treatment methods below). The cell movement direction was observed in the living cell workstation and the movement velocity, trajectory velocity, and direction of cosθ of cell movement within 3 h of treatment were calculated. HaCaT cells were divided into simulated electric field group and electric field treatment 1 h group, electric field treatment 2 h group, and electric field treatment 3 h group which were treated with 200 mV/mm electric field for corresponding time. HaCaT cells were divided into simulated electric field group and 100 mV/mm electric field group, 200 mV/mm electric field group, and 300 mV/mm electric field group treated with electric field of corresponding intensities for 3 h. The protein expression of acetylated α-tubulin was detected by Western blotting (n=3). HaCaT cells were divided into simulated electric field group and electric field treatment group, and the protein expression of acetylated α-tubulin was detected and located by immunofluorescence method (n=3). Data were statistically analyzed with Kruskal-Wallis H test,Mann-Whitney U test, Bonferroni correction, one-way analysis of variance, least significant difference test, and independent sample t test. Results: Within 3 h of treatment, compared with that in simulated electric field group, the cells in electric field treatment group had obvious tendency to move directionally, the movement velocity and trajectory velocity were increased significantly (with Z values of -8.53 and -2.05, respectively, P<0.05 or P<0.01), and the directionality was significantly enhanced (Z=-8.65, P<0.01). Compared with (0.80±0.14) in simulated electric field group, the protein expressions of acetylated α-tubulin in electric field treatment 1 h group (1.50±0.08) and electric field treatment 2 h group (1.89±0.06) were not changed obviously (P>0.05), while the protein expression of acetylated α-tubulin of cells in electric field treatment 3 h group (3.37±0.36) was increased significantly (Z=-3.06, P<0.05). After treatment for 3 h, the protein expressions of acetylated α-tubulin of cells in 100 mV/mm electric field group, 200 mV/mm electric field group, and 300 mV/mm electric field group were 1.63±0.05, 2.24±0.08, and 2.00±0.13, respectively, which were significantly more than 0.95±0.27 in simulated electric field group (P<0.01). Compared with that in 100 mV/mm electric field group, the protein expressions of acetylated α-tubulin in 200 mV/mm electric field group and 300 mV/mm electric field group were increased significantly (P<0.01); the protein expression of acetylated α-tubulin of cells in 300 mV/mm electric field group was significantly lower than that in 200 mV/mm electric field group (P<0.05). After treatment for 3 h, compared with that in simulated electric field group, the acetylated α-tubulin of cells had enhanced directional distribution and higher protein expression (t=5.78, P<0.01). Conclusions: Bio-intensity electric field can induce the directional migration of HaCaT cells and obviously up-regulate the level of α-ubulin acetylation after treatment at 200 mV/mm bio-intensity electric field for 3 h.

Abstract
Chiral materials have attracted significant research interests as they exhibit intriguing physical properties, such as chiral optical response, spin-momentum locking, and chiral induced spin selectivity. Recently, layered transition metal dichalcogenide 1T-TaS_{2} has been found to host a chiral charge density wave (CDW) order. Nevertheless, the physical consequences of the chiral order, for example, in electronic structures and the optical properties, are yet to be explored. Here, we report the spectroscopic visualization of an emergent chiral electronic band structure in the CDW phase, characterized by windmill-shaped Fermi surfaces. We uncover a remarkable chirality-dependent circularly polarized Raman response due to the salient in-plane chiral symmetry of CDW, although the ordinary circular dichroism vanishes. Chiral Fermi surfaces and anomalous Raman responses coincide with the CDW transition, proving their lattice origin. Our Letter paves a path to manipulate the chiral electronic and optical properties in two-dimensional materials and explore applications in polarization optics and spintronics.

Abstract
Abstract
The flow behavior and formability of Al-Li alloys under warm forming conditions are complicated because they depend on several factors, such as the deformation mode, strain, and strain rates. Therefore, characterizing the mechanical response, and deformation behavior of AA2060-T8 sheets under a wide range of temperatures and strain rates is crucial to develop a new thermo-mechanical processing (TMP) route for their wide industrial applications. Furthermore, determining the activation energy (Q) and predicting the flow behaviour of AA2060-T8 sheets under warm forming temperatures is meaningful for characterizing the mechanical response of AA2060-T8 sheets at warm deformation conditions. Thus, in this study, the Arrhenius constitutive model is developed to investigate the influence of strain rate and temperature on the warm deformation behaviour of AA2060-T8 and determine the activation energy (Q) of AA2060-T8, which is a crucial physical parameter to estimate the difficulties of deforming AA2060-T8 sheets under warm forming conditions.

Abstract
China was certificated malaria-free by WHO in 2021 and has continued to maintain malaria elimination. However, there are still huge challenges in malaria control in the border regions between Yunnan Province, China and Myanmar due to lack of geographic barriers and frequent cross-border travel. Hereby, we review the direction contributions of the Global Fund Malaria Program implemented by Health Poverty Action (HPA), an international non-governmental organization (NGO), to malaria elimination in China, and analyze the challenges of malaria control caused by external environmental factors, such as COVID-19, in regions where the Global Fund Malaria Program is implemented. In addition, some suggestions are proposed for cross-border collaboration on malaria control.

Abstract
Objective: To investigate the expression levels and clinical significance of glioma-associated oncogene homolog 1 (GLI1) and sonic hedgehog signaling molecule (Shh) in the malignant transformation of ovarian endometriosis (EM). Methods: The expressions of GLI1 and Shh were detected by real-time reverse transcription (RT)-polymerase chain reaction (PCR) and EnVision method in 50 cases of ovarian EM tissues, 35 cases of atypical endometriosis (aEM) and 50 cases of endometriosis-associated ovarian cancer (EAOC). The expression differences of two molecular markers in the malignant transformation of ovarian EM were compared, and the relationships between two molecular markers and the clinicopathological features and prognosis of EAOC were analyzed. Results: (1) RT-PCR showed that the expression levels of GLI1 mRNA in EM, aEM and EAOC group were 1.77±0.40, 3.54±0.44, and 7.80±0.24, respectively. The expression levels of Shh mRNA were 0.95±0.21, 3.14±0.35, and 5.41±0.31, respectively. GLI1 and Shh mRNA in EAOC group were significantly higher than those in EM and aEM group (all P<0.01), and there were statistically significant differences between EM and aEM group (all P<0.01). The percentages of GLI1 in ovarian EM, aEM and EAOC were 32% (16/50), 57% (20/35), and 66% (33/50), respectively, meanwhile, the positive expression rates of Shh were 20% (10/50), 49% (17/35), and 54% (27/50), respectively (all P<0.01). GLI1 mRNA expression was positively correlated with Shh mRNA expression in EAOC tissues (r=0.721, P<0.01). The expressions of GLI1 protein were proportionated to Shh protein in EAOC tissues (r=0.608,P=0.001). (2) The expression of GLI1 was significantly related to the International Federation of Gynecology and Obstetrics (FIGO) stage, cancer antigen 125 (CA125) levels, lymph node metastasis, and Platinum resistance in EAOC patients (all P<0.05). The expression of Shh were related to FIGO stage and lymph node metastasis in EAOC patients (all P<0.05). Logistic regression analysis showed that GLI1 expression was an independent risk factor for poor prognosis in EAOC patients (P<0.05). Kaplan-meier survival analysis showed that the overall survival rate of EAOC patients with high GLI1 expression and low GLI1 expression was 12.1% and 35.3%, respectively, with statistical significance (χ²=10.73, P<0.01). The overall survival rate of EAOC patients with high and low expression of Shh protein was 11.1% and 30.4%, in which there was statistically significant difference (χ²=3.96, P=0.047). Conclusion: GLI1 and Shh are highly associated with the malignant transformation of ovarian EM, which may play a role in promoting malignant degeneration of ovarian EM, and the high expression of GLI1 and Shh indicates a poor prognosis in EAOC patients.

Abstract
BACKGROUND Limited research has looked at the physical activity (PA) among Chinese children and adolescents with intellectual disabilities. METHODS The Children's Leisure Activities Study Survey-Chinese version was applied in evaluating PA levels among children and adolescents with intellectual disabilities. RESULTS The data indicated that only 29.5% of children and adolescents with intellectual disabilities met the PA recommendation. Boys engaged in significantly more MVPA and had higher energy expenditure than girls during weekdays and the whole week. The general trend in PA levels demonstrated a downtrend with the growth of age of children and adolescents with intellectual disabilities. The students aged 6-12 years old performed more MVPA and had greater energy expenditure compared with those 13-15 and 16-18 years old. CONCLUSION The level of PA among Chinese children and youths with intellectual disabilities is remarkably low, and there is a large gap compared with the PA recommendation.

Abstract
OBJECTIVE To evaluate the effects of interactive dynamic scalp acupuncture (IDSA), simple combination therapy (SCT), and traditional scalp acupuncture (TSA) on motor function and gait of the lower limbs in post-stroke hemiplegia patients. METHODS A total of 231 patients with post-stroke hemiplegia was randomly divided into IDSA (78 cases), SCT (78 cases), and TSA (75 cases) groups by a random number table. Scalp acupuncture (SA) and lower-limb robot training (LLRT) were both performed in the IDSA and SCT groups. The patients in the TSA group underwent SA and did not receive LLRT. The treatment was administered once daily and 6 times weekly for 8 continuous weeks, each session lasted for 30 min. The primary outcome measures included Fugl-Meyer assessment of the lower extremity (FMA-LE), berg balance scale (BBS), modified barthel index (MBI), and 6-min walking test (6MWT). The secondary outcome measures included stride frequency (SF), stride length (SL), stride width (SW), affected side foot angle (ASFA), passive range of motion (PROM) of the affected hip (PROM-H), knee (PROM-K) and ankle (PROM-A) joints. The patients were evaluated before treatment, at 1- and 2-month treatment, and 1-, and 2-month follow-up visits, respectively. Adverse events during 2-month treatment were observed. RESULTS Nineteen patients withdrew from the trial, with 8 in the IDSA and 5 in the SCT groups, 6 in the TSA group. The FMA-LE, BBS, 6MWT and MBI scores in the IDSA group were significantly increased after 8-week treatment and 2 follow-up visits compared with the SCT and TSA groups (P<0.05 or P<0.01). Compared with pre-treatment, the grade distribution of BBS and MBI scores in the 3 groups were significantly improved at 1, 2-month treatment and 2 follow-up visits (P<0.05 or P<0.01). The SF, PROM-H, PROM-K and PROM-A in the IDSA group was significantly increased compared with the SCT and TSA groups after 8-week of treatment (P<0.05 or P<0.01). Compared with the SCT group, ASFA of the IDSA group was significantly reduced after 8-week of treatment (P<0.05). SF, SL, PROM-K and PROM-A were significantly increased at the 2nd follow-up visit whereas the ASFA was significantly reduced in the IDSA group compared with the SCT groups at 1st follow-up visit (P<0.05 or P<0.01). The SF was significantly increased in the SCT group compared with the TSA group after 8-week treatment (P<0.05). Compared with the TSA group, PROM-K, PROM-A were significantly increased at the 2nd follow-up visit (P<0.05). CONCLUSIONS The effects of IDSA on lower-limb motor function and walking ability of post-stroke patients were superior to SCT and TSA. The SCT was comparable to TSA treatment, and appeared to be superior in improving the motion range of the lower extremities. (Registration No. ChiCTR1900027206).

Abstract
OBJECTIVE To compare the clinical effects of interactive dynamic scalp acupuncture (IDSA), simple combination therapy (SCT), and traditional scalp acupuncture (TSA) on cognitive function, depression and anxiety in patients with post-stroke cognitive impairment. METHODS A total of 660 patients with post-stroke cognitive impairment who were admitted to 3 hospitals in Shenzhen City between May 2017 and May 2020 were recruited and randomly assigned to the IDSA (218 cases), SCT (222 cases) and TSA groups (220 cases) according to a random number table. All the patients received conventional drug therapy for cerebral stroke and exercise rehabilitation training. Scalp acupuncture and computer-based cognitive training (CBCT) were performed simultaneously in the IDSA group, but separately in the morning and in the afternoon in the SCT group. The patients in the TSA group underwent scalp acupuncture only. The course of treatment was 8 weeks. Before treatment (M0), 1 (M1) and 2 months (M2) after treatment, as well as follow-up at 1 (M3) and 2 months (M4), the cognitive function of patients was assessed using the Mini-Mental State Examination (MMSE) and Montreal Cognitive Assessment Scale (MoCA) Scales; depression, anxiety, sleep quality, and self-care ability of patients were assessed using Hamilton Depression Rating Scale (HAMD), Hamilton Anxiety Rating Scale (HAMA), Pittsburgh Sleep Quality Index (PSQI), and Modified Barthel Index (MBI), respectively. During this trial, all adverse events (AEs) were accurately recorded. RESULTS There were no significant differences in the MMSE, MoCA, HAMD, HAMA, PSQI, and MBI scores among the 3 groups at M0 (all P>0.05). In the IDSA group, the MMSE, MoCA and MBI scores from M2 to M4 were significantly higher than those in the SCT and TSA groups, while the HAMD, HAMA and PSQI scores were significantly reduced (all P<0.01). The changes of all above scores (M2-M0, M4-M0) were significantly superior to those in the SCT and TSA groups (all P<0.01, except M4-M0 of HAMD). At M2, the severity of MMSE, HAMD, HAMA, PSQI and MBI in the IDSA group was significantly lower than that in the SCT and TSA groups (all P<0.01). There was no serious AE during this trial. CONCLUSIONS IDSA can not only significantly improve cognitive function, but also reduce depression, anxiety, which finally improves the patient's self-care ability. The effect of IDSA was significantly better than SCT and TSA. (Trial registration No. ChiCTR1900027206).

Abstract
Background To analyze the efficacy and safety of everolimus 5 mg/day in combination with endocrine drugs in the treatment of hormone receptor-positive, human epidermal growth factor receptor 2 (HER2)-negative metastatic breast cancer using real-world clinical data. Methods Clinical data of hormone receptor (HR)-positive and HER2-negative patients with advanced breast cancer treated with everolimus combined with endocrine drugs in our center between August 2012 and May 2017 were retrospectively analyzed. Curative effect and adverse reactions were evaluated. Results A total of 110 patients were enrolled in this study, and 87.3% received salvage chemotherapy. The median number of salvage treatment lines was 5 (range: 1–19). The median follow-up duration was 12 months (range: 1–56.3 months), the overall response rate (ORR) was 6.4%, the clinical benefit rate (CBR) was 31.8%, the median progression-free survival (mPFS) was 4.0 months (95% CI: 2.9–5.1 months), and the median overall survival (OS) was 17 months (95% CI: 12.1–21.9 months). The mPFS for patients who received ≤2 treatment line was 11.8 months (95% CI: 4.3–19.3 months). Univariate and multivariate analyses suggested that absence of liver metastases, secondary endocrine resistance, and number of metastasis sites <3 were the main factors influencing the benefit of everolimus combined with endocrine therapy. The most common adverse events of grade 3 were: stomatitis (5.5%), non-infectious pneumonia (1.8%), and erythra (1.8%). No grade 4 adverse reactions were observed. Conclusions Our results showed that everolimus (5 mg/day) combined with endocrine therapy was effective and relatively safe for patients with hormone receptor-positive, HER2-negative metastatic breast cancer.

Abstract
Abstract Objective To study the genetic polymorphism of whole mitochondrial DNA (mtDNA) genomes in She population in Zhejiang and to explore the maternal genetic structure of the She population. Methods Whole mtDNA genomes of 231 unrelated individuals from She population in Zhejiang Province were sequenced. The number of mutations and population genetics parameters such as, the haplotype diversity (HD), discrimination power (DP), and random match probabilities (RMP) were analyzed. The mtDNA haplogroups of Zhejiang She population were classified, and the maternal genetic relationships between She and nine other Chinese populations were estimated. Results In 231 Zhejiang She samples, 8 507 mutations (702 types) were observed and the samples were classified into 94 haplogroups. The HD, DP and RMP values were 0.998 6, 0.994 2 and 0.005 8, respectively. The lowest genetic differentiation degree (Fst=0.006 89) was detected between Zhejiang She population and southern Han population. Principal component analysis (PCA) and median-joining network analysis showed that the genetic distance of Zhejiang She population with Guangxi Yao, Yunnan Dai and Southern Han populations was relatively close, but the population still had some unique genetic characteristics. Conclusion The whole mtDNA genomes are highly polymorphic in Zhejiang She population. The Zhejiang She population contains complex and diverse genetic components and has a relatively close maternal genetic relationship with Guangxi Yao, Yunnan Dai and Southern Han populations. Meanwhile, Zhejiang She population has kept its unique maternal genetic components.

Abstract
Human challenge trial (HCT) is a test in which human volunteers are intentionally infected with pathogens in order to evaluate the efficacy of candidate preventive or therapeutic drugs. During the COVID-19 pandemic, the HCT of vaccines has aroused people's attention due to its significant advantages over clinical trial. This paper introduces the concept, development and application of HCT, the advantages and limitations of HCT for vaccine evaluation, and the consideration of future HCT of COVID-19 vaccine in China.

Abstract
Objective: To explore the application effect and evaluation of virtual reality technology in oral implant therapy training. Methods: In November 2018, one adult patient (female, 36 years old) with missing right mandibular first molar was treated in the Department of Implantology, School and Hospital of Stomatology, Fujian Medical University. The three-dimensional virtual models of mandible and implant surgery tools were established, and the virtual reality software (Unity 3D 5.5.1) was imported. Combined with the virtual reality head mounted display, a virtual reality training system simulating the dental implant treatment process was independently developed. Ten refresher doctors and 20 graduate students in Department of Implantology, School and Hospital of Stomatology, Fujian Medical University from September 2018 to December 2019 were recruited as the experimental objects (no clinical experience was found). According to the level and seniority of doctors, they were randomly divided into virtual training group and conventional training control group, which made the two groups comparable, with 15 in each group. Subjective scores (including anatomical structure, surgical field of vision, cavity preparation, implant placement and process mastery) were given after the corresponding training in the two groups, and the virtual reality training system was used to test. The mesial and distal direction, buccolingual direction, depth and angle deviation of implants before and after the training were analyzed, and the differences between the two groups were compared. Results: The subjective scores of five dimensions in the virtual training group were significantly higher than those in the conventional training control group (P<0.05). In the virtual training group, the mesial and distal, buccolingual, depth and angle deviation of implants were (0.73±0.33), (0.78±0.41), (0.61±0.32) mm and 6.66°±3.87°. All of them were significantly lower than those in the control group [(0.85±0.32), (1.12±0.38), (0.89±0.24) mm and 9.68°±3.74°] (P<0.05). Conclusions: The self-developed virtual reality system of oral implant has good application effect, good operability and predictability. It can be effectively carried out in implant education and training, and it can strengthen skills of doctors, and is conducive to the practical operation.

Abstract
Background The ongoing global coronavirus disease 2019 (COVID-19) pandemic is posing a serious public health threat to nations worldwide. Understanding the pathogenesis of the disease and host immune responses will facilitate the discovery of therapeutic targets and better management of infected patients. Metabolomics technology can provide an unbiased tool to explore metabolic perturbation. Methods Twenty-six healthy controls and 50 COVID-19 patients with mild, moderate, and severe symptoms in the Fifth Medical Center of PLA General Hospital from January 22 to February 16, 2020 were recruited into the study. Fasting blood samples were collected and subject to metabolomics analysis by liquid chromatography-mass spectrometry. Metabolite abundance was measured by peak area and was log-transformed before statistical analysis. The principal component analysis, different expression analysis, and metabolic pathway analysis were performed using R package. Co-regulated metabolites and their associations with clinical indices were identified by the weighted correlation network analysis and Spearman correlation coefficients. The potential metabolite biomarkers were analyzed using a random forest model. Results We uncovered over 100 metabolites that were associated with COVID-19 disease and many of them correlated with disease severity. Sets of highly correlated metabolites were identified and their correlations with clinical indices were presented. Further analyses linked the differential metabolites with biochemical reactions, metabolic pathways, and biomedical MeSH terms, offering contextual insights into disease pathogenesis and host responses. Finally, a panel of metabolites was discovered to be able to discriminate COVID-19 patients from healthy controls, and also another list for mild against more severe cases. Our findings showed that in COVID-19 patients, citrate cycle, sphingosine 1-phosphate in sphingolipid metabolism, and steroid hormone biosynthesis were downregulated, while purine metabolism and tryptophan metabolism were disturbed. Conclusion This study discovered key metabolites as well as their related biological and medical concepts pertaining to COVID-19 pathogenesis and host immune response, which will facilitate the selection of potential biomarkers for prognosis and discovery of therapeutic targets.

Abstract
BACKGROUND Overweight and obesity in children and adolescents has become a worldwide epidemic. There are several studies that have concentrated on the prevalence rate of children and adolescents with intellectual disabilities (ID), whereas data on such a population on the mainland of China remain unclear. The purpose of this study was to investigate the prevalence rate of overweight and obesity among school-aged children and adolescents with ID on China's mainland. METHODS This study employed a cross-sectional design to examine the body weight status of 1873 children and adolescents (ages 6-18 years old) with ID in 35 special education schools. Body mass index was calculated, and the concepts of overweight and obesity were defined according to the standard of the Working Group for Obesity in China. RESULTS Data indicated that 18.2% (95% CI: 16.5%-20.0%) of children and adolescents with ID were overweight and 14.4% (95% CI: 12.8%-16.0%) were obese. Boys with ID were more likely to be overweight than girls with ID (OR = 1.48[95% CI: 1.13-1.94], P < 0.05). Children and adolescents with Down syndrome or autism spectrum disorder had a trend to be classified as overweight (OR = 1.76[95% CI: 1.22-2.54], P < 0.05; OR = 1.57[95% CI: 1.17-2.09], P < 0.05, respectively) or obesity (OR = 1.82[95% CI: 1.23-2.69], P < 0.05; OR = 1.40 [95% CI: 1.02-1.93], P < 0.05, respectively) compared with those with ID without these conditions. Moreover, children and teenagers with ID living in urban areas had a predisposition to be overweight (OR = 2.16[95% CI: 1.14-4.09], P < 0.05) or obese (OR = 3.25[95% CI: 1.41-7.50], P < 0.05) relative to those who lived in rural areas. CONCLUSION Results indicated that in China, the prevalence rate of overweight and obesity among school-aged children and adolescents with ID was remarkably high. Therefore, future research should make every effort to focus on reducing and preventing overweight and obesity of this population in China.

Abstract
Abstract Objective To assess the feasibility of the rbcL sequence of chloroplast DNA as a genetic marker to identify Cannabis sativa L. Methods The rbcL sequences in 62 Cannabis sativa L. samples, 10 Humulus lupulus samples and 10 Humulus scandens DNA samples were detected, and 96 rbcL sequences of the Cannabaceae family were downloaded from Genbank. Sequence alignment was performed by MEGA X software, the intraspecific and interspecific Kimura-2-Parameter (K2P) genetic distances were calculated, and the system clustering tree was constructed. Results The rbcL sequence length acquired by sequencing of Cannabis sativa L. and Humulus scandens were 617 bp and 649 bp, respectively, and two haplotypes of Cannabis sativa L. were observed in the samples. The BLAST similarity search results showed that the highest similarity between the sequences acquired by sequencing and Cannabis sativa L. rbcL sequences available from Genbank was 100%. The genetic distance analysis showed that the maximum intraspecific genetic distance (0.004 9) of Cannabis sativa L. was less than the minimum interspecific genetic distance (0.012 9). The results of median-joining network and system clustering tree analysis showed that Cannabis sativa L. and other members of the Cannabaceae family were located in different branches. Conclusion The rbcL sequence could be used as a DNA barcode for identifying Cannabis sativa L., and combined with comparative analysis of the rbcL sequence and system cluster analysis could be a reliable and effective detection method for Cannabis sativa L. identification in forensic investigation.

Abstract
Objectives: To investigate the predictive value of inflammatory biomarkers in patients with unresectable hepatocellular carcinoma (HCC) for outcomes following the combination treatment of transarterial chemoembolization (TACE) plus sorafenib. Materials and Methods: A total of 314 (270 male and 44 female) treatment-naïve patients with unresectable HCC treated by TACE plus sorafenib between January 2011 and December 2018 were enrolled in the retrospective study. The primary outcome was overall survival (OS). The secondary outcome was progression-free survival (PFS). Neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) were obtained within 3–7 days before the initial TACE and the median value of the NLR and PLR was considered as the cut-off value. Results: The median value of NLR and PLR was 2.42 and 100, respectively. The median OS and PFS of the entire cohort were 18.7 months (95% CI: 16.8–20.6) and 9.1 months (95% CI: 8.5–9.8), respectively. The low NLR and PLR group showed improved OS and PFS compared with the high NLR and PLR group [21.8 months (95% CI: 15.2–28.5) vs. 15.4 months (95% CI: 12.4–18.3), p < 0.0001; 21.6 months (95% CI: 15.8–27.5) vs. 14.9 months (95% CI: 11.9–17.8), p = 0.00027, respectively]. In addition, the low NLR and PLR group also provided a longer PFS than the high NLR and PLR group [10.4 months (95% CI: 8.9–12.0) vs. 8.1 months (95% CI: 7.1–9.2), p = 0.00022; 10.3 months (95% CI: 8.6–11.9) vs. 8.2 months (95% CI: 7.2–9.2), p < 0.0001, respectively]. High NLR and PLR at baseline were predictive factors of poor OS (p = 0.02 and p = 0.004) and PFS (p = 0.045 and p = 0.005). Conclusion: This study showed the prognostic value of quantitative inflammatory biomarkers in correlation with OS and PFS in unresectable HCC patients undergoing TACE plus sorafenib treatment.

Abstract
OBJECTIVE To compare the efficacy of scalp acupuncture combined with lower-limb intelligent feedback training and lower-limb intelligent feedback training alone for lower-limb motor dysfunction after stroke. METHODS A total of 154 patients with lower-limb motor dysfunction after stroke were randomly divided into an observation group (76 cases, 6 cases dropped off) and a control group (78 cases, 8 cases dropped off). The patients in both groups were treated with conventional medication and exercise rehabilitation training. In addition, the patients in the observation group were treated with scalp acupuncture combined with lower-limb intelligent feedback training. The scalp acupuncture was given at upper 1/5 of the anterior oblique line of parietal temporal area and upper 1/5 of the posterior oblique line of parietal temporal area. The patients in the control group were treated with lower-limb intelligent feedback training alone. All the treatment was given once a day, 6 days a week, totaling for 8 weeks. The affected-side lower-limb Brunnstrom stage and modified Ashworth scale (MAS) grade, 6-minute walk test (6MWT), Berg balance scale (BBS) score and modified Barthel index (MBI) score were evaluated before and after treatment in the two groups. The plantar pressure was measured by gait function evaluation system. RESULTS Compared before treatment, the Brunnstrom stage in the two groups was improved after treatment (P<0.01); the MAS grade in the observation group was improved after treatment (P<0.01); the Brunnstrom stage and MAS grade in the observation group were superior to those in the control group (P<0.01, P<0.05). After treatment, the 6MWT, BBS and MBI scores in the two groups were increased (P<0.05), and those in the observation group were higher than those in the control group (P<0.05). After treatment, the touchdown area of health-side hind foot, affected-side front-hind foot and bilateral full foot in the observation group was increased (P<0.05), and the touchdown area of affected-side front-hind foot and full foot in the observation group was larger than that in the control group (P<0.05). The weight-bearing ratio of health-side forefoot and full foot in the observation group was decreased after treatment (P<0.05), and the weight-bearing ratio of affected-side forefoot, hind foot and full foot was increased after treatment (P<0.05). The weight-bearing ratio of health-side forefoot and full foot in the observation group was lower than that in the control group (P<0.05), and the weight-bearing ratio of health-side hind foot, affected-side forefoot and affected-side full foot in the observation group was higher than that in the control group (P<0.05). CONCLUSION The scalp acupuncture combined with lower-limb intelligent feedback training could reduce the muscle tension of lower limbs, promote the separation movement mode of lower limbs, improve the plantar pressure distribution, and improve the balance ability and walking ability in stroke patients, and the curative effect is better than lower-limb intelligent feedback training alone.

Abstract
OBJECTIVE To investigate the protective effect of Lycium barbarum polysaccharide (LBP) against testicular spermatogenic injury in mice with oxidative stress (OS) and its mechanism. METHODS A unique OS model was made in 1.5-month-old mice with mitochondrial inner membrane-like peptide-2 mutation (Immp2l-/-), which were fed with water (the negative control group) or LBP in water at the concentration of 20 mg/kg (the LBP intervention group), and wild-type Immp2l+/+ mice used as normal controls and fed with water only. Then all the mice were sacrificed at 13 months old and the testis tissue harvested for observation of pathological changes by HE staining, measurement of routine semen parameters, and detection of the apoptosis of spermatogenic cells by TUNEL and the expression levels of glutathione peroxidase 4 (GPX4) and apoptosis-inducing factor (AIF) by immunohistochemistry and Western blot. RESULTS Thinned testicular cortex was observed in the negative controls, with evident vacuolar degeneration and reduced numbers of germ cells and elongated spermatids in the lumen of the seminiferous tubules, but all these pathological changes were improved and the germ cells at different levels orderly arranged in the LBP intervention group. Compared with the normal controls, the mice in the negative control group showed dramatically reduced sperm count ([72.89 ± 8.28] vs [20.78 ± 1.45] ×106, P<0.01) and the percentages of progressively motile sperm (PMS) ([58.62 ± 6.15]% vs [18.37 ± 2.67]%, P<0.01) and morphologically normal sperm (MNS) ([65.81 ± 7.69]% vs [20.33 ± 3.17]%, P<0.01) and increased apoptosis of spermatogenic cells ([1.45 ± 0.43]% vs [7.14 ± 0.78]%, P<0.01). LBP intervention, however, significantly increased the sperm count ([45.25 ± 3.39] ×106, P<0.05), PMS ([36.34 ± 4.56]%, P<0.05) and MNS ([38.72 ± 3.63]%, P<0.05) and decreased the apoptosis of spermatogenic cells ([2.28 ± 0.07]%, P<0.01). The mice in the LBP intervention group, in comparison with the negative controls, exhibited remarkably up-regulated expression of GPX4 (2.75 ± 0.48 vs 1.43 ± 0.17, P<0.05) and down-regulated expression of AIF (2.43 ± 0.15 vs 1.35 ± 0.51, P<0.05). CONCLUSIONS Lycium barbarum polysaccharide at 20 mg/kg can reduce testicular spermatogenic injury in Immp2l-/- mice with oxidative stress through GPX4 and AIF pathways.

Abstract
OBJECTIVE To compare the efficacy of interactive scalp acupuncture, scalp acupuncture alone and scalp acupuncture plus cognitive training for cognitive dysfunction after stroke. METHODS A total of 660 patients with cognitive dysfunction after stroke were randomly divided into an interactive scalp acupuncture group (218 cases, 18 cases dropped off), a scalp acupuncture group (220 cases, 20 cases dropped off) and a scalp acupuncture plus cognitive training group (222 cases, 22 cases dropped off). All the patients were treated with routine medication and exercise rehabilitation training. The interactive scalp acupuncture group was treated with scalp acupuncture on the parietal midline, and contralateral anterior parietal temporal oblique line and posterior parietal temporal oblique line at the same time of cognitive training; the scalp acupuncture group was treated with scalp acupuncture alone, and the scalp acupuncture plus cognitive training group was treated with scalp acupuncture and cognitive training in the morning and afternoon respectively. All the treatments were given once a day, 6 times a week for 8 weeks. Montreal cognitive assessment (MoCA) scale score was used to evaluate the cognitive function before treatment, 4 weeks and 8 weeks into treatment. RESULTS Compared before treatment, the total score of MoCA was increased after 4-week treatment and 8-week treatment in the three groups (P<0.01), and the score in the interactive scalp acupuncture group was higher than that in the scalp acupuncture group and the scalp acupuncture plus cognitive training group (P<0.05, P<0.01). Compared before treatment, each item score of MoCA was increased after 8-week treatment in the three groups (P<0.01), and the score in the interactive scalp acupuncture group was higher than that in the scalp acupuncture group and the scalp acupuncture plus cognitive training group (P<0.01). Except for the attention, the remaining items scores of MoCA in the scalp acupuncture plus cognitive training group were higher than those in the scalp acupuncture group (P<0.01). CONCLUSION The interactive scalp acupuncture could significantly improve the cognitive function in patients with cognitive dysfunction after stroke, and the efficacy is superior to scalp acupuncture alone and scalp acupuncture plus cognitive training.

Abstract
Abstract
Background: Because Pertuzumab hasn't been approved in China until 2020y, trastuzumab has been standard neoadjuvant treatment for HER2-positive breast cancer. But we don't know which is the optimal chemotherapy with or without anthracyclines in the trastuzumab-based HER2-blockade. We designed this clinical trial to compare efficacy and safety between anthracycline and carboplatin in combination with docetaxel and trastuzumab as neoadjuvant therapy. Methods: From Apr, 2013 to Apr, 2019, 124 patients were enrolled. 60 patients were randomly assigned to the ATH-TH group and 64 to the TCH group. The treatment plan is showed as following, 1. TCH group: Trastuzumab(8mg/kg loading dose followed by 6mg/kg maintenance dose on day 1 every 3 weeks) combined with carboplatin(AUC=6 on day1 every 3 weeks) and docetaxel (75mg/m2 d1 every 3 weeks), total 6 cycles ; 2. ATH-TH group: Trastuzumab combined with doxorubicin( 50mg/m2 on day1 every 3 weeks) and docetaxel (75mg/m2 d1 every 3 weeks) after 4 cycles, followed by Trastuzumab plus docetaxel (75mg/m2 d1 every 3 weeks) 4 cycles. Primary endpoint was pCR(ypT0/is/ypN0). Second endpoints included safety, event-free and overall survial (EFS and OS). This trial is registered with ClinicalTrials.gov, number NCT 02510781.Results: Baseline Patients’ characteristics were well balanced between ATH-TH group and TCH group: median age 49y/48y, hormone receptor positive 51.7% vs 46.9%, II stage 60.0% VS 64.0%, III stage 33.3% VS 32.8%. The pCR rate was no significant difference(P=0.457) in ATH-TH 56.7%(95% CI:43.8%-69.6% ) and TCH group 50.0% ( 95% CI :37.4%-62.6%) .In hormone positive subgroup, the pCR rate was 36.7% ( 95% CI:18.4%-55.0% )for TCH group, and 51.6% (95% CI:33.0%-70.2%) for ATH-TH group (P=0.24). In hormone negative subgroup, the pCR rate was 61.8% (95% CI:44.6%-79.0% )for TCH group, and 62.1% ( 95% CI:43.3%-80.9%) for ATH-TH group (P=0.98). The most common adverse events were hematologic toxicities. ATH-TH group had higher 3/4 grade leukocyte decrease rates than TCH group ( 86.7% VS 43.8%, p<0.001) and higher 3/4 thrombocytopenia (11.7% VS 1.6%, p<0.016). ATH-TH group had more FN than (43.3% VS 3.1%, p<0.001). LVEF change and cardiac events were similar between two group Four-year EFS estimates were 94.5% for ATH-TH and 91.1% for TCH (p=0.768, HR=0.82, 95% CI: 0.22-3.06). Four-year OS estimates were 97.5% for ATH-TH and97.8%for TCH (p=0.562, HR=2.0, 95% CI: 0.18-22.2). Conclusions: This is the first prospective randomised trial compare neoadjuvant therapy regimen ATH-TH with TCH in HER2-positive breast cancer. We acquired similar pCR rate, four-year EFS and OS but less toxicity in TCH group compared with ATH-TH. Long-term follow-up is required to confirm these results.

Abstract
To improve the removal efficiency of dissolved organic matter in wastewater treatment plant (WWTP) effluent, electro-hybrid ozonation-coagulation (E-HOC) is proposed and the treatment characteristics and removal mechanism for WWTP effluent and ibuprofen (IBP) are investigated. The E-HOC process has a better removal effect on dissolved organic matter in WWTP effluent, achieving 46.4%, 20.0%, 19.4%, 36.1%, and 49.7% higher removal than EC, ozonation, pre-ozonation-EC, electrocoagulation-ozonation, and chemical coagulation, respectively. To determine the mechanism of the E-HOC process, quenching experiments and electron paramagnetic resonance (EPR) were conducted, which confirmed that metal coagulants can be used as a catalyst to effectively increase the generation of the hydroxyl radical (·OH). Synergistic effects between ozone and the coagulants (SOC) were also found to be involved. Fourier-transform infrared spectroscopy (FT-IR) illustrated that the surface hydroxyl groups of the coagulant (hydrolyzed species produced by Al anode electrolysis) were the active sites for the generation of·OH in the SOC reaction. Based on a kinetics analysis of organic matter removal in the E-HOC system, SOC effects and ozonation played dominant roles in the E-HOC process. Additionally, the SOC created a new pathway for·OH formation.

Abstract
In this study, to solve the problem of salinity enrichment in industrial wastewater recycling, a hydrolytic bioreactor was continuously operated to treat high-color printing and dyeing wastewater (PDWW) with salinity build-up. Nearly complete color removal was achieved even with salinity build-ups from 0.5 to 4 g·L-1 in the influent. Pyrosequencing of 16S rRNA genes showed that the salinity build-up results in the decrease of microbial species from 882 to 631; however, the biodiversity of the bacterial community remains stable. Metagenomic analysis indicated that salinity build-up caused no obvious effect on the overall function of the bacterial community, but altered the abundance of specific decoloring genes. Proteobacteria dominated in the bioreactor, and Methanothrix and Geobacter were the dominant genera under low salinity conditions. Proteobacteria increased in abundance with salinity build-up. Desulfovibrio and Desulfococcus were the two predominant genera in the bioreactor fed with sodium sulphate salinity build-up, demonstrating opposite responses to the sodium stress. PICRUSt functional analysis showed that the relative abundance of the decolorizing enzymes SOD1 and SOD2 decreased significantly, but the relative abundance of CAT and TYR increased, ensuring the stability of the decolorizing function of the hydrolysis biological system. From the perspective of the functional genes of hydrolysis decolorization, this study explored the effect of salinity build-up on the microbial community and function of hydrolysis, providing a theoretical basis for the study of decolorization and organic matter removal mechanism of PDWW under the condition of salinity build-up.

Abstract
Objective: To explore the influencing factors of job burnout of medical staff and provide reference for the formulation of intervention measures. Methods: From November to December, 2018, a questionnaire survey was conducted among medical staff in a general hospital by using the research design of the current situation survey. A total of 1193 questionnaires were distributed and 939 questionnaires were returned, with a recovery rate of 78.7%, including 891 valid questionnaires and an effective recovery rate of 94.9%. Social support rating scale (SSRs) was used to evaluate social support, and Maslach Burnout Scale (MBI-GS) was used to evaluate job burnout. Single factor analysis was performed by chi square test and Fisher exact probability method. To explore the influencing factors of job burnout by using disordered multi classification logistic. Results: The average age was (27.47 ± 4.22) years old, female accounted for 71.5% (637/891) . The total physical examination rate of job burnout was 46.6%. The scores of emotional exhaustion, cynicism and decreased sense of achievement were (10.10±3.75) , (6.14±3.43) , (17.91±4.13) respectively. Multiple logistic regression analysis showed that, compared with the non detected job burnout, the young, working for 1-3 years, average sleep ≤6 hours, and poor social support were more likely to have mild job burnout (OR=0.91, 0.40, 2.25, 2.38, P<0.05) ; female, high night shift frequency in the past year, average sleep ≤6 h. Those with poor social support were more likely to have moderate to severe job burnout (OR=1.59, 2.94, 4.01, 2.40, 3.66, P<0.05) . Conclusion: Corresponding measures should be taken to reduce job burnout and improve work efficiency.

Abstract
Objective: To explore the characteristics of executive function in children with attention-deficit/hyperactivity disorder comorbid with high functioning autism. Methods: A total of 165 children with attention-deficit/hyperactivity disorder (ADHD group), 65 children with attention-deficit/Hyperactivity disorder comorbid with high functioning autism (ADHD-HFA group), and 84 healthy controls (control group) (based on the criteria of DSM-5) were recruited from the Outpatient Clinic of Child Healthcare Department of Shen Zhen Children's Hospital. The Rey complex figure test (RCFT), trail making test (TMT), Stroop color-word test were used to assess working memory, shifting and inhibition. Results: ADHD group (2.1±1.9, 7±5, 2.1±2.0 and 7±5) and ADHD-HFA group (2.0±2.0, 7±6, 2.0±2.1 and 6±5) performed worse than control group (3.4±2.0, 10±5, 3.4±2.0 and 10±6) in Rey complex figure test (all P<0.05). ADHD group ((171±8) s, (27.40±0.82) s and (52.29±1.62) s) and ADHD-HFA group ((197±11) s, (29.7±1.1) s and (58.6±2.1) s) group took longer time on the TMT-2, Stroop2 and Stroop4 test than control group ((135±18) s, (22.4±1.9) s and (38.7±3.8) s) (all P<0.05). In children with low intelligence quotient (IQ), ADHD group ((30±8) s) and ADHD-HFA group ((34±9) s) performed worse on Stroop3 test than control group ((20±4) s) (all P<0.05). In children with average IQ, ADHD group ((19±5) s and (24±8) s) took longer time on the Stroop1 and Stroop3 test than control group ((16±3) s and (19±4) s) (all P<0.05). In children with high IQ, ADHD-HFA group ((20±8) s) spent more time on Stroop1 than control group ((15±4) s) (P<0.05). Inattention symptoms were associated with the time on TMT-2 of ADHD-HFA group (r=0.275 and 0.329, all P<0.05). The score of item 1 in autism spectrum screening questionnaire (ASSQ) was negatively correlated with immediate recall structure and detail scores as well as delay structure scores of Rey complex figure test (r=-0.358, -0.326 and -0.306, all P<0.05). The score of item 4 was positively correlated with errors of Stroop4 (r=0.296, P<0.05). The score of item 22 was positively correlated with time of color interference (r=0.279, P<0.05). Conclusions: Children with ADHD-HFA are likely to demonstrate the spatial working memory, shifting and inhibition deficits associated with ADHD alone. Some domains of executive function impairment in ADHD-HFA group are related with symptoms of inattention/hyperactivity and autism.

Abstract
Background Taenia pisiformis is one of the most common intestinal parasites in canines, and leads to serious economic losses in the rabbit breeding industry. Exosome-like vesicles from parasites play crucial roles in host-parasite interactions by transferring cargo from parasites to host cells and by modulating host immunological response through inducing production of host-derived cytokines. Nevertheless, the mechanism by which exosome-like vesicles from T. pisiformis cysticercus regulate the macrophage immune response remains unknown. Methods Using ultracentrifugation, we isolated exosome-like vesicles from excretory/secretory products (ESP) of T. pisiformis cysticercus. The morphology and size of purified vesicles were confirmed by transmission electron microscopy (TEM) and nanoparticle tracking analysis (NTA). The components of proteins and miRNAs within these vesicles were identified by proteomic analysis and high-throughput small RNA sequencing. The biological function of targets of exosomal miRNAs was predicted by Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis. Moreover, the expression of Th1- and Th2-type immune response associated cytokines in RAW264.7 macrophages were evaluated by qPCR and ELISA. We found that exosome-like vesicles were typical cup-shaped vesicles with diameters from 30 to 150 nm. A total of 87 proteins were identified by proteomic analysis, including proteins prominently associated with exosome-like vesicles biogenesis and vesicle trafficking. 41 known miRNAs and 18 novel miRNAs were identified in the exosome-like vesicles. Eleven selected miRNAs, including 7 known miRNAs (miR-71-5p, miR-10a-5p, miR-let-7-5p, miR-745-3p, miR-219-5p, miR-124-3p and miR-4989-3p) and 4 novel miRNAs (novel-mir-3, novel-mir-7, novel-mir-8 and novel-mir-11) were validated to exist in metacestiodes and exosome-like vesicles of T. pisiformis cysticercus by qPCR. The functions of most targets of exosomal miRNAs were mainly associated with signal transduction and the immune system. Additionally, T. pisiformis cysticercus-derived vesicles induced the production of IL-4, IL-6, IL-10, IL-13 and Arg-1, but downregulated the expression of IL-12, IFN-γ and iNOS in RAW264.7 macrophages. Conclusions We demonstrated that proteins and miRNAs enclosed within exosome-like vesicles from T. pisiformis cysticercus have immunomodulatory functions. Furthermore, exosome-like vesicles were shown to induce the macrophage Th2-type immune response in vitro. Our study suggests that exosome-like vesicles play an important role in the interaction between cysticerci and their hosts.![]()

Abstract
Objective: To analyze the long-term efficacy and safety of thalidomide on refractory Crohn's disease (CD). Methods: A total of 79 patients with refractory CD in the First Affiliated Hospital of Sun Yat-sen University treated with thalidomide were enrolled in this retrospective study from September 2005 to July 2018. Clinical effects and adverse drug reactions were recorded and assessed. Results: In this cohort,69 patients were treated with thalidomide for ≥6 months. Sixty-eight patients among the 69 patients achieved complete clinical remission and were followed up for a median 33.5 months (range, 7-110 months). Seventeen cases relapsed during follow-up. The cumulative probabilities of remaining in remission at 12, 24, 60 months were 88.6% (95%CI 80.6%-96.6%), 80.7% (95%CI 70.3%-91.1%), 53.7% (95%CI 32.1%-75.3%) respectively. Disease activity was the only variable associated with relapse risk, with a hazard ratio (HR) of 3.559 for Crohn's disease activity index (CDAI) ≥220(95%CI 1.213-10.449, P<0.05). Adverse reactions were recorded in 42 (53.2%) patients including12 (15.2%) leading to discontinuation of thalidomide. No serious side effects were observed in all subjects. Conclusions: This study suggests a long-term benefit of maintenance treatment with thalidomide in refractory CD.Moderate to severe patients have an increased risk of relapse. The high incidence of drug adverse reactions may restrain the clinical application of thalidomide.

Abstract
CePd2Al2 crystallizes in the CaBe2Ge2-type tetragonal structure (P4/nmm, 129) and undergoes a phase transition to the orthorhombic Cmme structure at around 13 K. Its inelastic neutron spectra reveal an additional magnetic excitation that was ascribed to electron-phonon interaction leading to a formation of a new quantum quasi-bound vibron state. We present the first-principles calculations of the crystal field excitations and lattice dynamics calculations of the phonon dispersions to compare with the experimental data. The calculated crystal field energy splitting in CePd2Al2 agrees well with the model used to describe the experimental neutron scattering spectra. The first excited crystal field level moves to higher energies when undergoing the transformation from tetragonal to orthorhombic structure, in agreement with the experiment. The analysis based on calculated elastic constants and lattice dynamics calculations show that in both tetragonal and orthorhombic structures there are no imaginary modes for any q-wave vector within the Brillouin zone, and therefore the lattice structures are stable. The phonon dispersions and density of states are calculated for both crystal structures of CePd2Al2 and its nonmagnetic counterpart LaPd2Al2. The results generally agree well with the experimental data including the high phonon density of states around 12 meV. The phonon density of states is also used to calculate the mean squared displacement, Debye temperature, lattice heat capacity and compared with similar properties of the available experiment.

Abstract
Polymorphonuclear neutrophils (PMNs) are the most abundant leukocytes and are among the first line of immune system defense. PMNs can form neutrophil extracellular traps (NETs) in response to some pathogens. The release of NETs plays an important role in trapping and killing invading parasites. However, the effects of NETs on parasitic trematode infections remain unclear. In the present study, water buffalo NET formation, triggered by the newly excysted juveniles (NEJs) of Fasciola gigantica, was visualized by scanning electron microscopy. The major components of the structure of NETs were characterized by immunofluorescence. Viability of flukes incubated with water buffalo PMNs were examined under light microscopy. The results revealed that F. gigantic juveniles triggered PMN-mediated NETs. These NETs were confirmed to comprise the classic characteristics of NETs: DNA, histones, myeloperoxidase and neutrophil elastase. Although NETs were formed in response to viable larvae, the larvae were not killed in vitro. These results suggest that NET formation may serve as a mechanism to hamper the migration of large larvae to facilitate immune cells to kill them. This study demonstrates, for the first time, that parasitic trematode juveniles can trigger NET formation.

Abstract
Background Spermatogonial stem cell (SSC) transplantation technology as a promising option for male fertility preservation has received increasing attention, along with efficient SSC purification technology as a necessary technical support; however, the safety of such application in patients with tumors remains controversial. Methods In this study, we used a green fluorescent protein mouse xenograft model of B cell acute lymphocytic leukemia. We isolated and purified SSCs from the testicular tissue of model mice using density gradient centrifugation, immune cell magnetic bead separation, and flow cytometry. The purified SSCs were transplanted into convoluted seminiferous tubules of the nude mice and C57BL/6 male mice subjected to busulfan. The development and proliferation of SSCs in the recipient testis were periodically tested, along with whether B cell acute lymphocytic leukemia was induced following SSC implantation. The genetic characteristics of the offspring obtained from natural mating were also observed. Results In testicular leukemia model mice, a large number of BALL cells infiltrated into the seminiferous tubule, spermatogenic cells, and sperm cells in the testis tissue decreased. After spermatogonial stem cell transplantation, the transplanted SSCs purified by immunomagnetic beads and flow cytometry methods colonized and proliferated extensively in the basement of the seminiferous tubules of mice; a large number of spermatogenic cells and sperm were found in recipient testicular tissue after 12 weeks of SSC transplantation. In leukemia detection in nude mice after transplantation in the three SSC purification groups, a large number of BALL cells could be detected in the blood of recipient mice 2–3 weeks after transplantation in the density gradient centrifugation group, but not in the blood of the flow cytometry sorting group and the immunomagnetic bead group after 16 weeks of observation. Conclusions In this study, we confirmed that immunomagnetic beads and flow cytometry methods of purifying SSCs from the testicular tissue of the testicular leukemia mouse model could be safely applied to the SSC transplantation technology without concomitant tumor implantation. The results thus provide a theoretical basis for the application of tumor SSC cryopreservation for fertility preservation in patients with tumors.

Abstract
Abstract
Currently, Aluminium (Al) alloys are increasingly used in the aerospace and automobile industries because of their outstanding properties such as lightweight and corrosion resistance properties. On the other hand, the applications of these materials are limited due to their poor formability especially at room temperature. Although hydroforming technology is one of the technique used to improve the formability of Al alloys, it still cannot fulfil the requirements of designers and manufacturers to form thin-walled complex shaped components. It has been found that high-speed forming is able to improve the formability of lightweight metals at room temperature. Thus, this investigation aims at investigating the effect of the novel technology called impact hydroforming (high-strain-rate forming) on the formability of Al alloys. Impact hydroforming (IHF) technology is proposed by combining the advantages of high-speed forming and hydroforming, and it was used to address the issues of quasi-static hydroforming. A high strain rate uniaxial tensile test was accomplished using Hopkinson tensile bar to investigate the effect of high strain rate on the formability of Al alloys. Thereafter, an IHF bulge experiment setup was developed by making use of a light gas gun which can accelerate the projectile up to 300m/s. The results show that the ductility and the formability of the Al alloy increased under high strain rate conditions, which means that the high-speed forming which is the basics of IHF technology is an appropriate method to improve the formability of Al alloys and form complex shape components.

Abstract
Aconitine (ACO), the main active component in Aconitum carmichaelii Debeaux (family: Ranunculaceae), has high cardiotoxicity, however the mechanisms of this effect remain unclear. Paeoniflorin (PF), the main chemical ingredient in herbaceous peony, can protect the heart from damage through antioxidant, vasodilatory and other effects. In this study, we focused on the mechanism by which PF reduces ACO cardiotoxicity. We selected H9c2 cells as the experimental model. MTT assay, Western blot analysis and real-time PCR were used to measure cell proliferation, apoptosis, ion channels and oxidative stress. Cell proliferation was significantly increased, the Bcl-2/Bax ratio and p53 level were upregulated, and Caspase-3 was slightly reduced in the ACO+PF group compared with the ACO group. SCN5A mRNA expression was significantly increased in the ACO+PF group compared with the ACO group, while RyR2 and Cx43 mRNA expression was decreased. Compared with the ACO group, the ACO+PF group showed marked decreases in extracellular lactate dehydrogenase (LDH) and intracellular malondialdehyde (MDA), while there was no difference in intracellular superoxide dismutase (SOD). The above data demonstrate that the cardiotoxicity of ACO in H9c2 cells was significantly decreased by PF.

Abstract
OBJECTIVE To investigate the feasibility of constructing a mouse model of spermatogonial stem cell (SSC) transplant recipient by high-temperature heat stress. METHODS Four-week-old C57BL/6 male mice and B6(Cg)-Tyrc-2J/J coat color gene homozygous mutant male mice were heat-treated at 43 ℃ for an hour in the incubator. The best transplantation time was determined by HE staining, immunohistochemistry and TUNEL and the SSCs were transplanted into the seminiferous tubules of the mice followed by regular observation of the proliferation, differentiation and spermiogenesis of the SSCs in the testis of the recipient mice. Then the recipients were mated with age-matched normal female mice and the epigenetic features of their offspring were observed. RESULTS After 3-5 days of high-temperature heat stress, the spermatogenic cells in the testicular seminiferous tubules of the recipient mice showed obviously decreased layers, disordered and loose arrangement, massive deletion, significant apoptosis, reduced mesenchymal cells and increased autophagy, which were basically recovered in about 12 days. At 8 weeks after transplantation, the isolated and purified SSCs were differentiated into spermatogenic cells and sperm with genetic function in the testicular seminiferous tubules of the recipient mice, and normal offspring were reproduced after natural mating. CONCLUSIONS High-temperature heat stress can be used as an efficient method for rapid construction of the mouse model of spermatogonial stem cell transplantation recipient.

Abstract
Objective: To investigate the epidemiologic and behavioral characteristics of HIV among community population in Liangshan prefecture. Methods: We collected social demographic, behavioral and serological information by means of the monitoring questionnaire and serological tests. Data was analyzed by using the chi-square test and logistic regression. Results: From April to June of 2010 to 2015, 14 092 cases of community population were selected as the study objects, with 267 cases diagnosed as HIV positive patients. The HIV positive rates were 3.24%, 3.07%, 1.17%, 1.38%,1.42% and 1.25%, respectively. We observed that when community population having the following characteristics as: living in Butuo country (OR=3.83), being males (OR=1.77), being Yi nationality (OR=4.40) being widowed (OR=28.57), with history of drug abuse (OR=3.71) or injecting drug use (PWID) (OR=4.92), or history of needle sharing among PWID (OR=8.53), were under higher risks for HIV infection. With histories as: having had secondary or above levels of schooling (OR=0.59), having protected sex with regular partners (OR=0.21) and with non-regular partners (OR=0.46), they seemed to be somehow protected for getting HIV infection. Conclusion: The positive HIV rates of HIV among community population in Dechang, Ningnan and Butuo varied from 0.10% to 8.77% while the HIV transmission among general population remained challenging.

Abstract
OBJECTIVE To investigate the influence of the Rho/ROCK signaling pathway on the anti-cryodamage ability of human sperm and provide some theoretical evidence for the development of high-efficiency semen cryoprotectants. METHODS We collected semen samples from 25 healthy males, each divided into a fresh, a normal cryopreservation control and an Rho-inhibition group. Before and after freezing, we detected sperm motility, viability, membrane integrity, morphology, DNA fragmentation index (DFI), acrosomal enzyme activity (AEA) and mitochondrial membrane potential (MMP) and determined the expressions of RhoA and ROCK proteins in the sperm by immunofluorescence staining. RESULTS Compared with the normal cryopreservation control, the frozen-thawed sperm of the Rho-inhibition group showed significantly increased sperm motility ( [51.20 ± 7.70]% vs [57.50 ± 6.83]%, P = 0.002), survival rate ( [52.87 ± 5.07]% vs [60.24 ± 5.53]%, P = 0.001), membrane integrity ([59.78±5.56]% vs [67.10 ± 4.43]%, P = 0.001), percentage of morphologically normal sperm ([4.83 ± 1.11]% vs [7.46 ± 1.28], P = 0.001) and MMP (56.30 ± 4.28 vs 63.11 ± 2.97, P = 0.001), but decreased DFI ([27.64 ± 6.64]% vs [18.87 ± 4.07]%, P = 0.001). There was no statistically significant difference in the AEA of the frozen-thawed sperm between the control and Rho-inhibition groups (97.65 ± 9.31 vs 98.30 ± 11.33, P > 0.05). Immunofluorescence staining revealed extensive expressions of RhoA and ROCK proteins in the head and neck of the sperm. CONCLUSIONS The Rho/ROCK signaling pathway plays a role in the cryodamage to human sperm, and inhibiting the activity of Rho/ROCK can significantly improve the ability of sperm to resist cryodamage.

Abstract
Objective: To understand the epidemiological and etiological characteristics of mumps in Fujian province, 2005-2017. Methods: All the reported mumps cases were collected through the National Notifiable Disease Information Management System, 2005-2017. Active search and interviews were conducted to collect the information on vaccination of mumps. Throat swab specimens were collected for cells culture, genotyping and gene sequence analysis on mumps virus (MuV). Results: A total of 83 959 cases of mumps were reported in Fujian province from 2005 to 2017, with an average annual incidence of 17.6 per 100 000. Since 2007, the incidence appeared increasing but then decreasing, reaching the lowest level (7.5 per 100 000), after the setup of a monitoring program. Annually, the onset time of mumps showed an obvious two seasonal peaks, one from April to July, with a weakening trend, and the other from October to January with a rising trend. Most of the mumps cases occurred among students, kindergarten and scattered children (89.2%, 5 814/6 517), children aged 5-9 years (38.8%, 2 527/6 517), with cases reported from every region. Program from the pathogen surveillance showed that the transmission chain of G genotype mumps virus did exist in Fujian. Data from the sequence analysis revealed that mutations in the nucleotide of G genotype strain in 2015 had led to mutation of 6 amino acid sites in the SH gene coding region, resulting in the differences appearing in both nucleotide and amino acid homology with type A vaccine strain. Conclusions: The incidence of mumps decreased annually, in Fujian. Prevention programs should focus on primary and secondary school students. In Fujian province, we also noticed the transmission chain of mumps G genotype with some amino acid mutations in the SH gene coding region. Monitor programs on both epidemiologic and etiology, should be strengthened.

Abstract
MiR-222-3р has been implicated in tumor cell proliferation and has an important role in the differentiation and maturation of myogenic cells. However, its role in skeletal myoblast proliferation is still unclear. In this study, we found that miR-222-3р expression increases initially and then decreases during C2C12 myoblast proliferation. Using synthetic miRNA mimics and inhibitors in gain- or loss-of-function experiments, we snowed that miR-222-3р overexpression in C2C12 cells promotes myoblast proliferation and represses myofiber formation, while miR-222-3р downregulation has the opposite effect. Using a prediction program, BTG2 was identified as a possible target gene of miR-222-3р. During myogenesis, miR-222-3р mimics repress BTG2 expression, while miR-222-3р inhibitors promote BTG2 expression. Using dual-luciferase reporter assay, we further demonstrated that miR-222-3р specifically targets BTG2. Additionally, we show that siRNA-mediated downregulation of BTG2 expression in C2C12 myoblasts promotes the proliferation and suppresses differentiation. In conclusion, we provide a novel insight into the mechanism by which miR-222-3р regulates the proliferation and differentiation of C2C12 myoblasts by targeting BTG2. This information contributes to our understanding of the role of miRNAs in skeletal muscle development.
