Abstract
Objective: To analyze the trend of mortality rate and disability-adjusted life year (DALY) of colorectal cancer attributable to dietary risk factors from 1990 to 2019 in China. Methods: Mortality rate and DALY rate of colorectal cancer attributable to dietary risk factors (diet high in processed meat, diet high in red meat, diet low in calcium, diet in low in fiber, diet low in milk, diet low in whole grains, dietary risks) were collected from the Global Burden of Disease study 2019 (GBD2019). Joinpoint regression model was selected to analyze the trend and an age-period-cohort model was used to estimate the effects of age, period and birth cohort. Results: Joinpoint regression analysis showed that the age-standardized mortality rate and age-standardized DALY rate of colorectal cancer attributable to diet high in processed meat, diet high in red meat, diet low in milk, diet low in whole grains and dietary risks showed an upward trend (P<0.05) from 1990 to 2019, while those attributable to diet low in calcium and diet low in fiber showed a downward trend (P<0.05). The mortality rate and DALY rate of colorectal cancer attributable to diet high in processed meat, diet high in red meat, diet low in milk, diet low in whole grains and dietary risks in age groups from 65 to 79 years showed a quicker upward trend than those in age groups from 25 to 64 years. The mortality rate and DALY rate attributable to diet low in calcium and diet low in fiber in age groups from 65 to 79 years showed a slower downward trend than those in age groups from 25 to 64 years. The mortality rate and DALY rate of colorectal cancer attributable to diet high in processed meat, diet high in red meat, diet low in calcium, diet low in fiber, diet low in milk, diet low in whole grains, and dietary risks increased with age after adjusting for period effect and cohort effect (P<0.05). The mortality rate and DALY rate attributable to diet high in processed meat, diet high in red meat, diet low in calcium, diet low in milk, diet low in whole grains and dietary risks increased with period or cohort, while those attributable to diet low in fiber decreased with period or cohort. Period and cohort effect of dietary risk factors in this study were statistically significant (P<0.001). Conclusions: Disease burden of colorectal cancer attributable to dietary risk factors in China showed an upward trend in general. Elderly population is high at risk and more attention should be paid to science popularization and education on dietary risk factors in prevention and treatment of colorectal cancer.

Abstract
The theory of membrane anatomy has been widely used in the field of colorectal surgery. The key point to perform high quality total mesorectal excision (TME) and complete mesocolic excision (CME) is to identify the correct anatomical plane. Intraoperative identification of the various fasciae and fascial spaces is the key to accessing the correct surgical plane and surgical success. The landmark vessels refer to the small vessels that originate from the original peritoneum on the surface of the abdominal viscera during embryonic development and are produced by the fusion of the fascial space. From the point of view of embryonic development, the abdominopelvic fascial structure is a continuous unit, and the landmark vessels on its surface do not change morphologically with the fusion of fasciae and have a specific pattern. Drawing on previous literature and clinical surgical observations, we believe that tiny vessels could be used to identify various fused fasciae and anatomical planes. This is a specific example of membrane anatomical surgery.

Abstract
A total of 36 patients with suspected peritoneal dialysis (PD) catheter dysfunction in the First Hospital of China Medical University from June 2020 to August 2022 were included, and five patients with normal PD catheter were also included as the control group. There were 22 males and 19 females, and aged (45±21) years. The volume of rapid-phase drainage in the control and dysfunction groups was (2 086±65) and (1 181±637) ml, and the total drainage time was (15.2±1.3) and (38.3±14.9) min, respectively. The volume of rapid-phase drainage in the dysfunction group was reduced and the total drainage time was longer than that in the control group (both P<0.05). Compared with group with PD catheter migration, the duration of new bag instillation was prolonged, the drainage volume in the rapid-phase was reduced, the total drainage duration was prolonged, and the ultrafiltration volume was decreased in the group with PD catheter obstruction (all P<0.05). The rapid exchange test can provide an early preliminary diagnosis of PD catheter dysfunction and identify the type of catheter dysfunction.

Abstract
Objective: This study sought to investigate the impact of different obesity patterns on coronary microvascular function in male patients with non-obstructive coronary artery disease. Methods: We retrospectively analyzed clinical data of male patients diagnosed with suspected coronary microvascular dysfunction (CMD) in the First Hospital of Shanxi Medical University between December 2015 and August 2021. All patients underwent the one-day rest and stress 13N-ammonia positron emission tomography myocardial perfusion imaging. Overall obesity was defined by body mass index (BMI) ≥28 kg/m2 and abdominal obesity was defined by waist circumference ≥90 cm. Hyperemic myocardial blood flow (MBF)<2.3 ml·min-1·g-1 or coronary flow reserve (CFR)<2.5 were referred as CMD. All patients were grouped based on their BMI and waist circumference. MBF, CFR, the incidence of CMD, hemodynamic parameters, and cardiac function were compared among the groups. Results: A total of 136 patients were included. According to BMI and waist circumference, patients were categorized into 3 groups: control group (n=45), simple abdominal obesity group (n=53) and compound obesity group (n=38). Resting MBF did not differ between groups (F=0.02,P=0.994). Compared with the control group, hyperemic MBF was significantly lower in the simple abdominal obesity and compound obesity groups ((2.82±0.64) ml·min-1·g-1, (2.44±0.85) ml·min-1·g-1 and (2.49±0.71) ml·min-1·g-1, both P<0.05, respectively). Hyperemic MBF was comparable among the groups of patients with obesity (P=0.772). CFR was significantly lower in the simle abdominal obesity group compared with the control group (2.87±0.99 vs. 3.32±0.62,P=0.012). Compared with the control group, CFR tended to be lower in the compound obesity group (3.02±0.91 vs. 3.32±0.62,P=0.117). The incidence of CMD was significantly higher in both the simple abdominal obesity and compound obesity groups than in the control group (62.3%, 52.6% vs. 22.2%, both P<0.01, respectively). Waist circumference was an independent risk factor for male CMD (OR=1.057, 95%CI: 1.013-1.103, P=0.011). Conclusions: In male patients with non-obstructive coronary artery disease, abdominal obesity is associated with decreased coronary microvascular function. Male patients with simple abdominal obesity face the highest risk of CMD.

Abstract
Background The COVID-19 pandemic highlighted the stark health inequities affecting minority ethnic populations in Europe. However, research on ethnic inequities and healthcare utilisation in children has seldom entered the policy discourse. A scoping review was conducted in the UK, summarising and appraising the quantitative evidence on ethnic differences (unequal) and inequities (unequal and unfair or disproportionate to healthcare needs) in paediatric healthcare utilisation. Methods Embase, Medline and grey literature sources were searched for studies published 2001-2021. Studies that found differences and inequities were mapped by ethnic group and healthcare utilisation outcome. They were appraised using the National Institute for Health and Care Excellence appraisal checklists. The distribution of studies was described across various methodological parameters. Results Of the 61 included studies, most found evidence of ethnic variations in healthcare utilisation (n = 54, 89%). Less than half attempted to distinguish between ethnic differences and inequities (n = 27, 44%). Studies were concentrated on primary and preventive care and hospitalisation, with minimal evidence on emergency and outpatient care. The quality of studies was often limited by a lack of theory underpinning analytical decisions, resulting in conflation of difference and inequity, and heterogeneity in ethnic classification. The majority of studies examined children's ethnicity but overlooked parent/caregiver ethnicity, and also didn't investigate patterns across age, year or location. Conclusions To improve the validity, generalisability and comparability of research on ethnicity and paediatric healthcare utilisation, findings from this scoping review were used to develop recommendations for future research. These lessons could be applied more broadly across the European context to improve evidence generation and evidence-based policy-making to reduce inequities in healthcare. Key messages • Quantitative studies of ethnicity and paediatric healthcare utilisation in the UK lack the use of sound theoretical frameworks, and often do not distinguish between ethnic differences and inequities. • The quality of future studies can be improved with greater attention to how ethnicity is classified and analysed, alongside specific considerations for examining healthcare utilisation in children.

Abstract
AIM To investigate the performance of a generative adversarial network (GAN) model for staging liver fibrosis and its radiomics-based nomogram for predicting cirrhosis. MATERIALS AND METHODS This two-centre retrospective study included 434 patients for whom input data of ultrasound images and histopathological data (obtained within 1 month of ultrasound examinations) were assigned to the training cohort (249 patients), the internal cohort (92 patients), and the external (93 patients) cohort. A data augmentation method based on a GAN model was used. The discriminative performance was evaluated for classifying fibrosis of S4 and ≥S3. Deep-learning radiomics features were extracted for the prediction of cirrhosis (S4). To perform feature reduction and selection, the least absolute shrinkage and selection operator (LASSO) algorithm was applied. Radiomics scores, along with clinical factors, were incorporated into a nomogram using multivariable logistic regression analysis. The performance of the models was estimated with respect to discrimination power, calibration, and clinical benefits. RESULTS The areas under the receiver operating characteristic curve (AUCs) values of the GAN were 0.832/0.762 (≥S3), and 0.867/0.835 (S4) for internal/external test sets, respectively. The radiomics nomogram that intergrated radiomics scores and clinical factors showed good calibration and discrimination ability of 0.922 (AUC) in the training dataset, 0.896 in the internal dataset, and 0.861 in the external dataset. Decision curve analysis (DCA) demonstrated that the nomogram outperformed radiologist and haematological indices in terms of the most clinical benefits. CONCLUSIONS The GAN model could be applied to discriminate fibrosis stages, and a favourable predictive accuracy for diagnosing cirrhosis was achieved using a deep-learning radiomics nomogram.

Abstract
OBJECTIVE Obstructive jaundice (OJ) is a common clinical pathological syndrome in hepatobiliary surgery. High incidence of multiple organ injuries during perioperative period and its associated mortality remains challenging in clinical practice. Omega-3 polyunsaturated fatty acids (ω-3 PUFA) is an important enteral immune nutrition. This study investigated the protective role of ω-3 PUFA in the regulation of inflammatory response in OJ. MATERIALS AND METHODS Seventy-two rats were randomly divided into obstructive jaundice (OJ) group, obstructive jaundice + ω-3 PUFA group (OJPUFA) group, and sham group. OJ model was created by ligation of the bile duct. Abdominal thoracic catheter was placed to collect lymph. Body weight, liver function, serum and lymphatic levels of TNF-α, IL-1β, IL-10, HMGB1, and nitric oxide (NO) were measured on day 3, day 7, and day 14 after operation. Hematoxylin staining and Alcian blue-periodic acid-Shiff (AB-PAS) staining were performed on the ileum tissue. Protein and mRNA expression of HMGB1, TLR4, and NF-κB p65 were measured at the aforementioned time points. RESULTS The general condition, including body weight and liver function, were worse in the OJ and the OJPUFA group compared to that in the sham group. On day 14, the body weight recovery and liver function were significantly better in the OJPUFA group than those in the OJ group were (p<0.05 for all). No marked change in the serum and lymphatic levels of TNF-α, IL-1β, IL-10, HMGB1 and NO was observed in the sham group after operation, while corresponding levels in the OJ and the OJPUFA groups were significantly higher. Compared with the OJPUFA group, serum and lymphatic levels of the above factors were consistently higher in the OJ group and were significantly higher on day 14 (p<0.05 for all). At the same time, ω-3 PUFA lowered the damage of intestinal villi and intestinal mucosal epithelium. It also improved the number and function of goblet cells in intestinal mucosal epithelium. The protein and mRNA expression of HMGB1, TLR4, and NF-κB p65 were significantly higher in the OJ group than those in the OJPUFA group (p<0.05 for all). CONCLUSIONS ω-3 PUFA has protective effect in the management of obstructive jaundice. It can regulate the inflammatory response and reduce its damage to intestinal structure. Reducing the activation of HMGB1/TLR4/ NF-κB pathway might be a mechanism for its protective effect. We suggested that ω-3 PUFA and drugs targeted HMGB1/TLR4/NF-κB pathway might be potential treatment strategies in obstructive jaundice.

Abstract
OBJECTIVE We aimed to systematically review biological agents' efficacy and safety in patients with Takayasu arteritis (TAK). MATERIALS AND METHODS A systematic literature search of 7 electronic databases, including MEDLINE (via PubMed), EMBASE, Elsevier ScienceDirect, EBSCO, Springer Link, Web of Science, and Cochrane Library on the efficacy of biological agents on patients with TAK was conducted. Only studies published in English and with a sample size >5 patients with TAK were included. Two reviewers independently selected studies, extracted data and assessed its methodological quality. Random effects meta-analyses of various effect measures were performed. RESULTS According to the title and abstract, 961 studies were identified and screened. Subsequently, 31 studies from 29 observational studies and 2 randomized-controlled trials (RCTs), which included a total of 517 patients with TAK that met the inclusion and exclusion criteria, were selected. Observational studies showed a high risk of bias. Pooled remission rates of biological agents were 66% (95% CI: 58%-73%; I2=59%), and the remission rates of anti-tumor necrosis factor (TNF) agents and tocilizumab (TCZ) were similar: 65% (95% CI: 56%-73%; I2=49%) and 70% (95% CI: 55%-86%; I2=69%), respectively. Pooled relapse rates were 23% (95% CI: 15%-31%; I2=66%). The relapse rate was 28% (95% CI: 16%-40%; I2=68%) for anti-TNF agents and 17% (95% CI: 7%-26%; I2=49%) for TCZ. The remission rate of TCZ was slightly higher (p>0.05), but the relapse rate was statistically significantly lower than that of anti-TNF agents (p=0.017). Furthermore, biological agents significantly decreased the doses of glucocorticoid (GC) and levels of acute phase inflammation markers (ESR, CRP) while the proportion of patients with new angiographic lesions or progression of previously noted lesions were 11% (95% CI: 4%-18%; I2=59%). RCTs with a small sample size showed abatacept was ineffective, and TCZ was underpowered to detect a difference in time to relapse compared to placebo. The most common adverse event of biological agents was infection (6%, 95%CI: 2%-10%). No deaths were reported. CONCLUSIONS Although the beneficial effects of biological agents are encouraging in enhancing disease remission, reducing the levels of acute phase inflammation markers and decreasing the treatment doses of GC in patients with TAK, there is still a risk of relapse. More refined studies with larger cohorts are necessary before drawing a definitive opinion.

Abstract
Brown planthopper (BPH), white-backed planthopper (WBPH) and small brown planthopper (SBPH), are the closely related rice pests that perform differentially on wheat plants. Using fecundity as a fitness measure, we found that SBPH well-adapted on wheat plants, followed by WBPH, while BPH had the worst performance. The transcriptomic responses of SBPH and BPH to wheat plants have been compared previously. To understand the different fitness mechanisms of three planthoppers, this study first investigated the transcriptomic responses of WBPH to rice and wheat plants. Genes involved in detoxification, transportation and proteasome were significantly enriched in WBPH in response to different diets. Moreover, comparative analysis demonstrated that most co-regulated genes in BPH and SBPH showed different expression changes; whereas most co-regulated genes in BPH and WBPH exhibited similar expression changes. Subsequently, this study also investigated the influences of host plants on the bacterial community of three planthoppers. The three planthoppers harboured distant diversity of bacterial communities. However, there was no dramatic change in bacterial diversity or relative abundance in planthoppers colonized on different hosts. This study illustrates generic and species-specific changes of three rice planthoppers in response to different plants, which deepen our understanding towards the host fitness for planthopper species.

Abstract
OBJECTIVE To compare the differentially expressed proteins between cypermethrin-resistant and -sensitive Culex pipiens pallens, so as to unravel the mechanism underlying the resistance to cypermethrin in Cx. p. pallens. METHODS A quantitative proteomic analysis was performed among cypermethrin-sensitive and -resistant isolates of Cx. p. pallens using isobaric tags for relative and absolute quantification (iTRAQ) labeling coupled with liquid chromatography with tandem mass spectrometry (LC-MS/MS). RESULTS A total of 164 differentially expressed proteins were identified between cypermethrin-sensitive and -resistant isolates of Cx. p. pallens, including 54 up-regulated proteins and 110 down-regulated proteins. A large number of cuticular proteins, larval cuticular proteins, pupal cuticular proteins and cuticular structural constituent proteins, which are associated with cytoskeletal structure and components, were differentially expressed between cypermethrin-sensitive and -resistant isolates of Cx. p. pallens. Thirteen proteins, which were involved in energy production and conversion, translation, ribosomal structure and biogenesis, lipid transport and metabolism, post-translational modification, protein turnover, chaperones, cytoskeleton and intracellular transportation, were validated to be differentially expressed between cypermethrin-sensitive and -resistant isolates of Cx. p. pallens, which may serve as potential markers of cypermethrin resistance. CONCLUSIONS Multiple insecticide resistance mechanisms contribute to the resistance to cypermethrin in Cx. p. pallens, including cuticular resistance and metabolic resistance, and the cuticular protein genes and cytochrome P450 enzymes may play an important role in the resistance of Cx. p. pallens to cypermethrin.

Abstract
Some grain processing by-products rich in digestible fiber are good feed resources for ruminants. This experiment was conducted to investigate the effects of replacing a portion of corn and corn stover with the combinations of corn bran and soybean hulls in the diet of fattening lambs on nutrient digestion, rumen microbial protein synthesis, and growth performance. A total of 36 Dorper × Small Thin-Tailed crossbred ram lambs (BW = 22.2 ± 0.92 kg; mean ± SD) were randomly divided into three groups, and each group was fed 1 of 3 treatment diets: 1) 0% corn bran and soybean hulls (control); 2) 9% corn bran and 9% soybean hulls (18MIX); and 3) 17% corn bran and 17% soybean hulls (34MIX). The feeding experiment was conducted for 70 days, with the first 10 days for adaption. The DM intake was higher for 34MIX (1635.3 g/d) than for control diet (1434.7 g/d; P = 0.001). Lambs fed 18MIX and 34MIX diets (230.2 and 263.6 g/d, respectively) had higher average daily gain and feed efficiency than those fed control diet (194.8 g/d; P < 0.01). Dry matter and NDF digestibility for 34MIX group (60.9 and 49.5%) were higher than for control (55.2 and 41.3%; P < 0.01). No difference was observed in nitrogen digestibility among treatment diets (P = 0.778). The lambs fed 34MIX diet excreted more urinary purine derivatives, indicating that more microbial protein was yielded than those fed control diet (P < 0.01), while 18MIX was not different from the other two diets (P > 0.05). The metabolizable protein supplies were improved with increasing co-products inclusion rate. The results indicated that corn bran and soybean hulls in combination can effectively replace a portion of corn and corn stover in the ration of finishing lambs with positive effect on nutrient digestion and growth performance.

Abstract
The objective of the study was to determine the long-term effects of melatonin treatment on cashmere production and hair follicle populations in cashmere goats and their activity in two consecutive cashmere growth cycles. Twenty-four female Inner Mongolian Cashmere goats were randomly allocated to two groups (n = 12), one of which received melatonin implants, the other being an untreated control group. Melatonin implants were subcutaneously inserted behind the ear at a dose of 2 mg/kg live weight on two occasions -April 30 and June 30, 2016. Hair samples were collected by combing in April of 2017 and 2018, and the weight, staple length, and diameter of the cashmere fibers were measured. Blood and skin samples were collected monthly between April and September 2016, and in April and September in 2017 for the analysis of melatonin concentration and the characteristics of secondary hair follicle populations, respectively. The results indicated that serum melatonin concentration in the treated goats was elevated (P < 0.05) relative to that of the control group, but only during the first growth cycle. Melatonin treatment of cashmere goats in one cashmere growth cycle increased the weight, staple length, and density (all P < 0.05) of the cashmere fibers and decreased fiber diameter (P < 0.01), but did not affect the characteristics of cashmere production in the subsequent annual cycle. Melatonin treatment had no effect on the population of skin secondary hair follicles for two consecutive cycles. However, in the first growth cycle after treatment, it advanced the onset of activity of skin secondary hair follicles by 2 mo (P < 0.05), and it increased the number of follicles that were active (P < 0.05). In summary, the melatonin treatment of cashmere goats in one cashmere growth cycle improved cashmere production for that cycle only, with no residual effects on the subsequent cycle, a technique acceptable to the cashmere goat industry. The enhancement of cashmere production after the treatment of goats with melatonin appears to involve the acceleration of the annual regeneration of skin secondary hair follicles and increased population of active secondary hair follicles in the skin of cashmere goats.

Abstract
The physical form of starter feed may affect the gastrointestinal development and the performance of ruminant. However, little information is available on how changes in the physical forms of starter feed influence the performance of lambs, especially during the pre- and post-weaning periods. The aim of this study was to investigate the effects of different physical forms of starter feeds on growth performance, nutrient digestibility, gastrointestinal enzyme activity, and morphology of pre- and post-weaning lambs. Twenty-four 8-day-old male Hu lamb (5.04 ± 0.75 kg BW) were randomly assigned to one of two dietary treatments: 1) a pelleted starter (PS) feed and 2) a textured starter (TS) feed, which included coarse mashed steam-flaked corn. From eight to thirty-five days of age (pre-weaning), the lambs were bottle-fed milk replacer (MR) at 2% of BW measured on day 8. All lambs were weaned at day 35 when feeding of MR was stopped. Six lambs for each treatment were euthanized at 21 or 42 days of age for sampling. The following results are obtained by variance analysis: TS lambs had a greater (P < 0.05) final BW, higher apparent digestibility of starch and ether extract, activities of α-amylase pre- or post-weaning, and higher (P < 0.05) average dry matter intake and lipase post-weaning in small intestine contents and had a trend of significantly higher average daily gain post-weaning (P = 0.07). Rumen development analysis of TS lambs showed a significantly higher (P < 0.05) relative weight of rumen post-weaning, greater papillae length, increased circular and layered muscle, increased sectional area pre- and post-weaning, and increased rumen papillae width post-weaning. Textured starter treatment increased the villus height and villus width (except jejunum pre-weaning) of the whole small intestine and villus height to crypt depth ratio of jejunum and ileum during the whole period and tended to increase the relative weight of the rumen pre-weaning (P = 0.07). The results indicated that TS feeding is more beneficial to lambs over the weaning transition than PS in promoting gastrointestinal development, intestinal enzyme activities, nutrient digestibility, and growth performance. The findings provide new insights into the selection of physical forms of starter feeds in lamb production. Further research with more animals and female lambs is needed to obtain a more complete conclusion.

Abstract
OBJECTIVE Recent studies have revealed that microRNAs (miRNAs) play a crucial role in the progression of tumorigenesis. Non-small cell lung cancer (NSCLC) is one of the most common malignancies worldwide. The aim of this study was to identify the exact role of hsa-miR-337 in the progression of NSCLC and to investigate the possible underlying mechanism. PATIENTS AND METHODS Hsa-miR-337 expression in NSCLC cells and 60 paired tissue samples were detected by Real Time-quantitative Polymerase Chain Reaction (RT-qPCR). Moreover, the functions of hsa-miR-337 in vitro were identified by transwell assay and wound healing assay, respectively. Furthermore, the underlying mechanism was explored by RT-qPCR, Western blot assay, and luciferase assay. RESULTS The expression level of hsa-miR-337 in NSCLC tissues was remarkably down-regulated when compared with that of adjacent normal samples. Moreover, the invasion and migration of NSCLC cells were significantly inhibited after overexpression of hsa-miR-337 in vitro. Moreover, after overexpression of hsa-miR-337 in vitro, the mRNA and protein levels of TCF7 were significantly down-regulated. Besides, the expression of TCF7 in NSCLC tissues was negatively correlated with the expression of hsa-miR-337. CONCLUSIONS The above results suggested that hsa-miR-337 could repress the migration and invasion of NSCLC cells through directly targeting TCF7. Furthermore, hsa-miR-337 might offer a new therapeutic intervention for NSCLC patients.

Flax seed meal (FSM) is rich in various nutrients, especially CP and energy, and can be used as animal protein feed. In animal husbandry production, it is a long-term goal to replace soybean meal (SBM) in animal feed with other plant protein feed. However, studies on the effects of replacing SBM with FSM in fattening sheep are limited. The aim of this experiment was to study the effects of replacing a portion of SBM with FSM on nutrient digestibility, rumen microbial protein synthesis and growth performance in sheep. Thirty-six Dorper × Small Thin-Tailed crossbred rams (BW = 40.4 ± 1.73 kg, mean ± SD) were randomly assigned into four groups. The dietary treatments (forage/concentrate, 45 : 55) were isocaloric according to the nutrient requirements of rams. Soybean meal was replaced with FSM at different levels (DM basis): (1) 18% SBM (18SBM), (2) 12% SBM and 6% FSM (6FSM), (3) 6% SBM and 12% FSM (12FSM) and (4) 18% FSM (18FSM). The rams were fed in individual pens for 60 days, with the first 10 days for adaptation to diets, and then the digestibility of nutrients was determined. There was no significant difference in DM intake, but quadratic (P < 0.001) effects on the average daily gain and feed efficiency were detected, with the highest values in the 6FSM and 12FSM groups. For DM and NDF digestibility, quadratic effects were observed with the higher values in the 6FSM and 12FSM groups, but the digestibility of CP linearly decreased with the increase in FSM in the diet (P = 0.043). There was a quadratic (P < 0.001) effect of FSM inclusion rate on the estimated microbial CP yield. However, the values of intestinally absorbable dietary protein decreased linearly (P < 0.001). For the supply of metabolisable protein, both the linear (P = 0.001) and quadratic (P = 0.044) effects were observed with the lowest value in the 18FSM group. Overall, the results indicated that SBM can be effectively replaced by FSM in the diets of fattening sheep and the optimal proportion was 12.0% under the conditions of this experiment.

Abstract
OBJECTIVE To explore the effect of miR-543-3p on the recovery of locomotor function after spinal cord injury (SCI) by regulating tumor necrosis factor superfamily member 15 (TNFSF15) mediated inflammation and apoptosis. MATERIALS AND METHODS Macrophages were isolated from the abdominal cavity of 2-3 months old Sprague-Dawley (SD) rats and cultured. The levels of miR-543-3p, tumor necrosis factor superfamily member 15 (TNFSF15), TNF-like molecule 1A (TL1A) and nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) after transfection of miR-92b-5p into activated macrophages were detected by quantitative Real-time polymerase chain reaction (qRT-PCR). Moreover, the mRNA expressions of miR-543-3p, TNFSF15, TL1A and NF-κB after SCI in rats were detected by qRT-PCR. Meanwhile, the protein expressions of tumor necrosis factor (TNF-α), interleukin-1 β (IL-1β) and Caspase8 were detected by Western blot. After intrathecal injection of miR-543-3p mimics, the mRNA expressions of miR-543-3p, TNFSF15, TL1A and NF-κB and the protein expressions of TNF-α, IL-1β and Caspase8 in spinal cord injured area of mice were measured by qRT-PCR and Western blot, respectively. Basso Beattie Bresnahan (BBB) locomotor rating scale was used to determine the recovery of locomotor function after spinal cord injury and injection of miR-543-3p mimics. RESULTS Compared with inactivated cells, the expression of miR-543-3p in activated macrophages was significantly declined. However, the levels of TNFSF15, TL1A and NF-κB were significantly elevated. The expressions of TNFSF15, TL1A and NF-κB were remarkably downregulated after transfection of miR-543-3p. In addition, the level of miR-543-3p was significantly downregulated, accompanied by an increase in TNFSF15, TL1A and NF-κB in SCI rats. Accordingly, the protein levels of TNF-α and IL-1β and Caspase8 were also significantly increased. However, the expressions of TNFSF15, TL1A and NF-κB were significantly down-regulated in rats injected with miR-543-3p mimics, whereas the protein levels of TNF-α and IL-1β and Caspase8 were significantly suppressed. Finally, compared with SCI group, the recovery of locomotor function in miR-543-3p mimics administration group was significantly improved. CONCLUSIONS After SCI, miR-543-3p can inhibit the activity of NF-κB by suppressing the inflammatory aggravation of TNFSF15 and decreasing its product TL1A. MiR-543-3p leads to the improvement of neuron protection and locomotor function via attenuating inflammatory reaction and cell apoptosis.

Abstract
OBJECTIVE To elucidate the effect of estrogen on right ventricular remodeling of pulmonary arterial hypertension (PAH) induced by monocrotaline (MCT) in rats and its underlying mechanism. MATERIALS AND METHODS Male Sprague- Dawley (SD) rats were adaptively fed for one week, and then, randomly divided into control group, MCT group, MCT+17-β estradiol (50 mg·kg-1·d-1) group, and MCT+17-β estradiol (100 mg·kg-1·d-1) group, with 8 rats in each group. PAH rat model was constructed by subcutaneous injection of 60 mg·kg-1 MCT for consecutive 4 weeks. The right external jugular vein was intubated to monitor rat RVSP (right ventricular systolic pressure) and mPAP (mean pulmonary arterial pressure). After animal procedures, RV (right ventricle) and LV+S (left ventricle+ventricular septum) of rat were harvested and weighed. Rat tibia was collected and recorded for its length, followed by calculation of RV/(LV+S) and RV/length of the tibia. HE staining and Masson staining were conducted to observe the pathological change and collagen deposition in RV, respectively. RV was prepared for homogenate, followed by detection of total antioxidant capacity (T-AOC) and malondialdehyde (MDA) activities. Expression levels of collagen I, collagen III, NOX4, and NF-κB in RV of PAH rats were detected by qRT-PCR and Western blot. RESULTS Lower RVSP, mPAP, RV/(LV+S) and RV/length of the tibia were observed in rats of MCT+17-β estradiol (50 mg·kg-1·d-1) group and MCT+17-β estradiol (100 mg·kg-1·d-1) group compared with those of MCT group. Injection of 17-β estradiol (50 mg·kg-1·d-1 and 100 mg·kg-1·d-1) in PAH rats remarkably alleviated pathological changes and collagen deposition in RV. T-AOC activity increased, whereas MDA activity decreased in PAH rats injected with 17-β estradiol. Expression levels of collagen I, collagen III, NOX4, and NF-κB in RV of PAH rats were all downregulated by 17-β estradiol treatment. CONCLUSIONS 17-β estradiol could remarkably alleviate MCT-induced right ventricular remodeling of PAH rats. It is suggested that 17-β estradiol exerts its protective role in PAH by inhibiting NOX4-mediated oxidative stress and NF-κB-mediated collagen deposition.

Abstract
Objective: To investigate the autofluorescence findings of retinal astrocytic hamartoma (RAH) in patients with tuberous sclerosis complex (TSC). Methods: It was a retrospective case series study. Twenty-three patients (35 eyes) who were referred to Department of Internal Medicine and Department of Ophthalmology, Peking Union Medical College Hospital between November 2012 and June 2018 with established TSC-associated RAH diagnosis were included. The findings of fundus autofluorescence, fundus photos and spectral-domain optical coherence tomography (SD-OCT) were retrospectively reviewed. RAH lesions were classified into three types based on the morphology shown in fundus photos. The fundus autofluorescence features of TSC-associated RAH were described. The Welch's test and Fisher's exact test were used for statistical analysis. Results: The patients were 8 males and 15 females aged (28±9) years old (range, 15-55 years). Seventy-two RAH lesions were examined, including 59 type 1 RAHs, 7 type 2 RAHs and 6 type 3 RAHs. According to fundus autofluorescence, type 1 RAHs could be further divided into reduced, speckled and background autofluorescence patterns, among which the hypoautofluorescence pattern accounted for the majority (69.5%, 41/59), while the speckled pattern was usually accompanied by outer retinal disorganization and discontinuation of photoreceptor outer segment as revealed by SD-OCT. No significant difference was revealed in tumor thickness for reduced, speckled and background autofluorescence patterns of type 1 RAHs [(490.2±97.9) vs. (589.2±221.6) vs. (463.0±76.2) μm respectively, F=1.426, P=0.283]. Among type 1 RAHs, the number of reduced autofluorescence pattern lesions found in perifoveal, peripapillary, inferonasal, inferotemporal, superonasal, superotemporal quadrants were 9, 4, 4, 7, 4, 13 respectively, while that of speckled autofluorescence pattern lesions were 3, 0, 3, 2, 3, 2 and background autoflurorescence pattern lesions 3, 0, 1, 1, 0, 0. No significant difference was revealed in location distribution (P=0.452) either. Type 2 RAHs featured numerous hyperautofluorescent spots or plaques, and calcification in type 2 RAHs varied in autofluorescence intensity. Type 3 RAHs, combining the features of type 1 and 2 RAHs, were characterized by central hyperautofluorescent spots and hypoautoflurescent rim, but the area of hyperautofluorescence was smaller than that of calcification as shown in fundus photos. Conclusions: In TSC, the fundus autofluorescence of RAHs varies from hypoautofluorescence to hyperautofluorescence patterns according to RAH types. The retinal involvement and calcification degree of TSC-associated RAHs could be reflected on the autofluorescence, which was beneficial to the full assessment.

Abstract
Objective: To explore the incidence, risk factors of cardiovascular events (CVE) and their impact on 30-day mortality in patients hospitalized with community-acquired pneumonia (CAP). Methods: This is a multicenter, retrospective study. Patients hospitalized with CAP from 5 teaching hospitals in Beijing, Shandong and Yunnan provinces during 1 January 2013 to 31 December 2015 were included and clinical data were retrieved from the Hospital Information System (HIS), and patients were divided into CVE group and non-CVE group. Age, sex, comorbidities, pneumonia severity index(PSI)/CURB-65 score, routine blood test, biochemical examinations, radiological findings on admission and mortality on 30-day after admission were analyzed. The primary endpoint was acute CVE during hospitalization, the secondary endpoint was 30-day death after admission. Multivariate Cox regression analysis was used to explore the risk factors for CVE. Kaplan-Meier survival curve was used to compare the difference on 30-day mortality between CVE patients and non-CVE patients by Log-rank test. Multivariate Cox regression model was used to assess the impact of CVE on the 30-day mortality among CAP patients after adjustment with age, sex, comorbidities, PSI/CURB-65 score. Results: A total of 3 561 CAP patients were included into the final analysis, including 210 (5.9%) patients in CVE group and 3 351 (94.1%) patients in non-CVE group. Compared with patients in non-CVE group, patients in CVE group were older (P<0.001), prevalence of hypertension, coronary heart disease, chronic heart failure, cerebrovascular disease, chronic obstructive pulmonary disease, chronic kidney disease, aspiration risk and bedrid were significantly higher (all P<0.001); prevalence of CURB-65 score 3-5 and PSI risk class Ⅳ/Ⅴ were also significantly higher (both P<0.001). The proportion of axillary temperature<36 ℃, respiratory rate≥30 beats/minutes, confusion, leukocytes>10×10(9)/L, hemoglobin<100 g/L, platelets>300×10(9)/L, albumin<35 g/L, blood urea nitrogen>7 mmol/L, fasting blood glucose>11 mmol/L, serum C-reaction protein>100 mg/L, serum procalcitonin≥2 μg/L, arterial pH<7.35, arterial PO(2)/FiO(2)≤300 mmHg (1 mmHg=0.133 kPa), and multilobar infiltrates and pleural effusion on chest X-ray or CT scan were significantly higher in CVE group than in non-CVE group(all P<0.05); the 30-day mortality was significantly higher in CVE group than in non-CVE group(P<0.001). The incidence of CVE was significantly higher in patients with cardiovascular and cerebrovascular disease(CVD) than in patients without CVD (13.9%(150/1 079) vs. 2.4%(60/2 482), χ(2)=178.737, P<0.001). Meanwhile, the incidence of CVE increased with PSI in patients with Ⅰ/Ⅱ, Ⅲ and Ⅳ/Ⅴ class, respectively(χ(2)=228.350, P<0.001); and CURB-65 score 0-1, 2 and 3-5, respectively (χ(2)=387.154, P<0.001). Cox regression analysis revealed that age (HR=1.05, 95%CI 1.02-1.09, P=0.002), coronary heart disease (HR=1.88, 95%CI 1.01-3.51, P=0.048), chronic heart failure (HR=4.25, 95%CI 1.89-9.52, P<0.001), PSI risk class (HR=1.66, 95%CI 1.50-2.62, P=0.029) and serum procalcitonin≥ 2 μg/L (HR=3.72, 95%CI 1.60-8.66, P=0.002) were independent risk factors for CVE in CAP patients. Kaplan-Meier curve showed that the survival probability of patients with CVE was significantly lower than patients without CVE (P<0.001). After adjustment for age, sex, comorbidities and PSI/CURB-65 score, Cox regression model showed that CVE was associated with increased 30-day mortality in CAP patients (HR=6.05, 95%CI 3.11-11.76, P<0.001). Conclusions: Although the incidence of CVE is not high in Chinese patients hospitalized with CAP, CVE is common in patients with severe pneumonia and in patients with CVD. Age, cardiovascular disease, PSI risk class and serum procalcitonin are the risk factors for CVE in this patient cohort. CVE is related to increased 30-day mortality in CAP patients.

Abstract
OBJECTIVE To explore the expression of pyrroline-5-carboxylate reductase 1 (P5CR1) and its clinical significance and function in gastric cancer (GC). PATIENTS AND METHODS Real Time-quantitative Polymerase Chain Reaction (RT-qPCR) and Western blot (WB) were performed to detect the expression of P5CR1 in GC tissues and normal cells. The correlation between the expression level of P5CR1 and the clinicopathological characteristics of GC patients was analyzed by the Chi-square test. Moreover, the potential of P5CR1 in predicting the postoperative prognosis of GC was assessed by Kaplan-Meier method and Log-rank test model. Clone formation, flow cytometry, scratch wound healing, and transwell assay were performed to explore the effects of P5CR1 on cell function of GC. RESULTS The expression of P5CR1 significantly increased in GC tissues and cell lines. Its expression was significantly correlated with tumor differentiation and TNM stage of GC patients. Moreover, the GC patients with lower expression of P5CR1 had a better overall survival (OS). In univariate analyses and multivariate analyses, the expression of P5CR1 was an independent prognosis index of GC. Knockdown of P5CR1 significantly attenuated clone formation, migration, and invasion abilities, while the apoptotic rate of GC cells increased. CONCLUSIONS P5CR1 was a novel factor involved in GC progression and constituted a potential biomarker and therapeutic target of GC.

Abstract
OBJECTIVE The aim of this study was to identify the role of long non-coding RNA PVT1 (lnc-PVT1) in the progression of ovarian cancer. PATIENTS AND METHODS The expression of lnc-PVT1 in ovarian cancer cells and 50 paired tissue samples were detected by quantitative Reverse Transcriptase-Polymerase Chain Reaction (qRT-PCR). Moreover, cell proliferation assay and transwell assay were performed to identify the function of lnc-PVT1 in vitro. QRT-PCR and Western blot were utilized to explore the possible underlying mechanism. RESULTS Compared with normal tissues, the expression of lnc-PVT1 T1 was remarkably upregulated in tumor tissues. Moreover, the proliferation and invasion of ovarian cancer were promoted after knockdown of lnc-PVT1 in vitro. Moreover, both the mRNA and protein levels of SOX2 were suppressed after knockdown of lnc-PVT1 in vitro. Besides, the expression of SOX2 in tumor tissues was positively correlated to lnc-PVT1. CONCLUSIONS Lnc-PVT1 could enhance the invasion and proliferation of ovarian cancer cells through upregulating SOX2, which might serve as a new therapeutic target for the treatment of ovarian cancer.

Abstract
OBJECTIVE To observe the morphological changes in the testes and ovaries of adult 12th-generation Oncomelania hupensis bred for 12 winters in Weishan Lake areas. METHODS The offspring of the adult O. hupensis snails bred in the Weishan Lake that were originated from the Yangzhou section of the Yangtze River was defined as the experiment group, while uninfected, adult O. hupensis snails captured from the marshland of the Yangzhou section of the Yangtze River served as the control group. Snails were dissected and intact testicular and ovarian specimens were sampled, routinely fixed, dehydrated, embedded, polymerized in an oven and sliced on an ultramicrotome. The sections were visualized under a transmission electron microscope, and the ultrastructure of the snail gonad was compared between the experiment and control groups. RESULTS Transmission electron microscopy showed "9 + 2" microtubules on the transverse sections of the tails of sperm cells in the testes of male snails in the control group, with triangular acrosomes and spiral, dense nuclei seen in the tip, while in the experiment group, the "9 + 2" microtubules disappeared on the transverse sections of the tails of sperm cells in the testes of male snails, with low chromatin density found in the tip. Transmission electron microscopy revealed clear nucleolus and nuclear membranes in the ova of female snail ovaries, and displayed yolk body, liposomes and endoplasmic reticulum in the cytoplasm, bilayer twists of nuclear membrane and a uniform nucleolus in the control group, while in the experiment group, smooth nuclear membrane and unclear nucleolus were observed in the ova of female snail ovaries, with few contents seen within cells. CONCLUSIONS Following breeding for 12 winters in the Weishan Lake, the 12th-generation O. hupensis snails fail to fully adapt to the natural environment in northern China, and the remarkable changes in the ultrastructure of the snail gonad may be a cause of gradual decline and even extinction of O. hupensis in the Weishan Lake areas.

Abstract
The brown planthopper (BPH), Nilaparvata lugens, is a major threat to rice production. The eggshell plays an important role in insect reproduction. The constituents and formation process of BPH eggshells remains largely unknown. Here, we report a novel eggshell-associated protein, NlChP38, containing an amelogenin domain, that is essential for normal ovulation in the BPH. NlChP38 is specifically expressed in the follicular cells from egg chambers at both RNA and protein levels. RNA interference of NlChP38 resulted in oocytes with loose and thin eggshell structure and caused ovulation difficulties. Immunofluorescence localization showed NlChP38 is deposited between follicular cells and oocytes during late choriogenesis. These results indicate that NlChP38 plays an important role in eggshell formation and could be a potential target for RNA interference control of the BPH.

Abstract
OBJECTIVE To explore the sensitivity of Culex pipiens pallens to common chemical insecticides in the southwestern region of Shandong Province, so as to provide a theoretical basis for the development of reasonable and effective mosquito control measures. METHODS The resistance of Cx. pipiens pallens larvae to 5 chemical insecticides, such as cypermethrin, deltamethrin, DDVP, propoxur, and acetofenate were tested by using the WHO biological test method in 2018, and the co-toxicity coefficients after compounding the above-mentioned insecticides were tested by using a drug compounding method. RESULTS The resistance indexes of Cx. pipiens pallens to cypermethrin, deltamethrin, DDVP, propoxur, and acetofenate in 3 cities were 144.43-557.54, 118.17-445.33, 6.44-19.00, 2.37-8.10, and 0.88-2.98, respectively, and expect the difference between the DDVP resistances of Cx. pipiens pallens in Jining City and Heze City was not statistically significant (P > 0.05), all the other differences were statistically significant (all P < 0.05). The synergistic coefficients of cypermethrin + DDVP, cypermethrin + propoxur, DDVP + acetofenate, and propoxur + acetofenate were 199.58 - 456.95, 190.56 - 292.37, 123.32 - 319.24, and 192.31 - 367.32, respectively. The lower synergism was observed by using the mixture of DDVP + propoxur (synergistic coefficient: 99.87-108.36) . CONCLUSIONS After decades of chemical control, Cx. pipiens pallens in the southwestern region of Shandong Province has produced different degrees of resistance to common chemical insecticides. Therefore, comprehensive control measures should be taken to control mosquito breeding and prevent the development of insecticide resistance.

Abstract
OBJECTIVE The aim of this study was to explore the role of long non-coding RNA (lncRNA) TCL6 in preeclampsia (PE) development and to investigate its underlying mechanism. PATIENTS AND METHODS The expression of TCL6 in 42 placental tissues of PE pregnancies and normal pregnancies was detected by quantitative Real Time-Polymerase Chain Reaction (qRT-PCR). Receiver Operating Characteristic (ROC) curve was applied to explore the relationship between TCL6 expression, urine protein level, blood pressure and neonatal weight of PE pregnancies. The proliferation and cell cycle of trophoblast cells after TCL6 knockdown were detected by cell counting kit-8 (CCK-8) assay and flow cytometry, respectively. Moreover, the specific role of TCL6 in cell cycle was detected by Western blot. RESULTS TCL6 was highly expressed in 42 placental tissues of PE pregnancies when compared with that of normal pregnancies. PE pregnancies with lower expression level of TCL6 exhibited significantly lower urinary protein level, as well as systolic and diastolic blood pressure than those with higher level. Besides, neonatal weight was significantly higher in PE pregnancies with lower expression level of TCL6. Meanwhile, downregulation of TCL6 resulted in remarkably increased proliferation and cell cycle of trophoblast cells. In addition, Western blot results indicated that TCL6 knockdown significantly upregulated CDK2 and downregulated PTEN in trophoblast cells. CONCLUSIONS TCL6 was highly expressed in placental tissues of PE patients. Overexpression of lncRNA TCL6 inhibited the proliferation of trophoblast cells and promoted PE development via targeting PTEN.

Abstract
Objective: To analyze the influencing factors on condom use among 35-years-or-older female sex workers (OFSWs) in Qingdao by using the three-level logistic model. Methods: From March to June 2014, OFSWs were recruited in Qingdao, using respondent-driven sampling. Related information on OFSWs and their recent five sexual partners (not including husband) were obtained by conducting a questionnaire survey on OFSWs. A Three-level logistic regression model was conducted to analyze the influencing factors of condom use between OFSWs and their sexual partners. Results: A total of 420 OFSWs participated the survey as well as information on 2 100 sexual partners. Results from the empty model showed that the use of condoms among OFSWs having an aggregation that related to the levels of working sites and their own behaviors. Results from the three-levels of logistic model analysis showed that, OFSWs that having had junior middle school education (OR=1.450, 95%CI: 1.054-1.994)/high school education or above (OR=2.264, 95%CI: 1.215-4.222), knowing the function of condom use (OR=2.004, 95%CI: 1.273-3.154) would have higher rates of condom use. OFSWs with higher score of attitude on condom use (OR=0.796, 95%CI: 0.745-0.849), having had syphilis infections in the past (OR=0.657, 95%CI: 0.478-0.902) would have lower rate of condom use. For the sexual partners, the rate of condom use among OFSWs' regular partners were higher than that of OFSWs' boyfriends (OR=15.291, 95%CI: 8.441-27.700; OR=29.032, 95%CI: 15.413-54.682). Conclusion: Condom use of OFSWs was affected by behaviors of both OFSWs themselves and their sexual partners. Prevention and control programs should focus on OFSWs and their sexual partners at the same time. The key intervention contents should include target populations as: OFSWs with low level of education, having had infections of syphilis, those who do not use condoms with their trusted partners.

Abstract
Objective: To explore the clinical features, etiological features and prognostic risk factors of long-term glucocorticoid users with community-acquired pneumonia (CAP). Methods: A retrospective study included 100 long-term glucocorticoid users with CAP (G-CAP group) from 11 hospitals of China between January 2014 and December 2014, while 100 non-immunocompromised patients with community-acquired pneumonia were enrolled as controls (nICH-CAP group). Characteristics including age, gender, underlying diseases, corticosteroids, symptoms, disease severity, imaging manifestations, etiology, respiratory failure, mechanical ventilation, whether the application of vasoactive drugs, antibiotics application, hospital mortality rate between the two groups were compared, and the prognostic factors of G-CAP were investigated using Logistic regression. Results: The peripheral blood lymphocytes[1.06(0.70, 1.68) vs 1.44 (0.87, 1.98)]in G-CAP group was less than nICH-CAP group (P<0.05). CT with pulmonary interstitial change (28.6% vs 9.9%), the proportion of patients with respiratory failure (25.0% vs 7.0%), mechanical ventilation (9.0% vs 2.0%), noninvasive mechanical ventilation (12.0% vs 2.0%), septic shock (9.0% vs 2.0%), and the hospital mortality rate (13.0% vs 3.0%) in G-CAP group were significantly higher than in nICH-CAP group (all P<0.05). Bacterial infection accounted for the highest proportion of infection (61.3%) in G-CAP group, but also virus infection (19.4%) and mixed infection (16.1%). Pseudomonas accounted for the highest proportion (47.4%) in bacterial infection of G-CAP. Logistic regression analysis showed that peripheral blood lymphocytes (OR=0.004, 95% CI: 0.000-0.234; P<0.05) and respiratory failure (OR=17.766, 95% CI: 4.933-131.0; P<0.05) were independent predictors of death in G-CAP group. Conclusions: The proportion of severe pneumonia and the mortality rate of patients with G-CAP are higher than the patients with nICH-CAP. Lymphopenia and respiratory failure are associated with poor outcome of patients with G-CAP.

Abstract
In insect eggs, the chorion has the essential function of protecting the embryo from external agents during development while allowing gas exchange for respiration. In this study, we found a novel gene, Nilaparvata lugens chorion protein (NlChP), that is involved in chorion formation in the brown planthopper, Nilaparvata lugens. NlChP was highly expressed in the follicular cells of female adult brown planthoppers. Knockdown of NlChP resulted in oocyte malformation and the inability to perform oviposition, and electron microscopy showed that the malformed oocytes had thin and rough endochorion layers compared to the control group. Liquid chromatography with tandem mass spectrometry analysis of the eggshell components revealed four unique peptides that were matched to NlChP. Our results demonstrate that NlChP is a novel chorion protein essential for egg maturation in N. lugens, a hemipteran insect with telotrophic meroistic ovaries. NlChP may be a potential target in RNA interference-based insect pest management.

Abstract
Objective: To explore the effect of peripheral blood genomic DNA methylation on the relationship between methyl donor status and risk of breast cancer. Methods: A case-control study was conducted. Each three hundred breast cancer cases and controls were consecutively recruited. Food frequency questionnaire was used to collect dietary information. Amounts on folate, methionine, choline and betaine intake were calculated. Blood samples were collected for DNA extraction. Peripheral blood genomic DNA methylation was measured by using the Methyl Flash(TM) Methylated DNA Quantification Kit. Pathway analysis was used to examine the effect of genomic DNA methylation on the relations between methyl donor status and risk of breast cancer. Results: The genome DNA methylation rates were 0.46%±0.25% and 0.53%±0.34%, respectively on both cases and controls, with differences statistically significant (P<0.01). Results from the pathway analysis, results showed that methionine consumption was related to genomic DNA methylation (β=0.065, P<0.05) while genomic DNA methylation was related to the risk of breast cancerk (β=-0.027, P<0.05), respectively. Conclusions: The level of peripheral blood genomic DNA methylation in breast cancer cases was significantly lower than that in the controls. Genomic DNA methylation seemed to have played a mediated role between methionine and the risk of breast cancer.

Abstract
UNLABELLED Quantitative computed tomography (QCT) was used to investigate sex-related variations in cortical and trabecular bone of the femoral neck. Cortical bone thickness of women in the superior quadrant was thinner than that of men, and the cortex in all four quadrants was negatively associated with age in women. INTRODUCTION This cross-sectional study aimed to investigate sex-related similarities and differences in femoral neck structure in an elderly Chinese population by QCT bone investigational toolkit (BIT) analysis. METHODS This study included 207 male (67.9 ± 7.7 years; range, 55-87 years) and 400 female subjects (68.0 ± 8.7 years; range, 55-96 years). BIT module was used to measure cortical and trabecular bone in anatomic quadrants of the femoral neck. Measurements of cortical thickness (Ct.Th), cortical vBMD (Ct.vBMD), trabecular vBMD (Tb.vBMD), and integral vBMD (It.vBMD) at the femoral neck were determined in four anatomical sectors. RESULTS The greatest difference between sexes, after adjusting for age, height, and weight, was in Ct.Th of Quadrant Supero-anterior (SA), which was 27.4% lower in women (p<0.001). Ct.Th of Quadrant Supero-posterior (SP) was 15.1% lower in women (p = 0.027). Ct.Th and Tb.vBMD in all four quadrants appeared to be negatively associated with age in females, whereas no significant relationship was observed in males, except Ct.Th of Quadrant SP. CONCLUSIONS The superior femoral neck geometry between males and females was significantly different, even after adjustment for body size and age, and the sub-regional cortical and trabecular bone negatively age-related changes in women indicated that women apparently have a more vulnerable geometrical outcome with age for fractures than men.

Abstract
Parity anomaly refers to the violation of coordinate reflection symmetry induced by the quantum fluctuations. It is proposed to exist in a graphene-like system with a finite bare mass for Dirac fermions, and manifests itself as a parity-violating quantum correction to the current of each species of fermions. Coulomb interaction greatly increases the fermion mass, and produces various types of excitons. Of particular interest is the ρ-exciton, which is directly connected to parity anomaly and can be generated by absorbing a specific photon. The exciton is a particle-hole bound state, and can be regarded as condensed-matter analogue of meson composed of quark-anti-quark pair. By virtue of this correspondence, we analyze the optical conductivity and calculate the mass of ρ-exciton by employing the Shifman-Vainshtein-Zakharov sum rule method that is widely used in the studies of hadron phenomenology. We show that ρ-exciton leads to a sharp peak in the optical conductivity, which is observable in optical experiments. Moreover, we study the impact of scalar-like excitons on two-photon processes by computing the decay amplitude, and also find peaks in the Raman spectra.

Abstract
A elderly woman patient,with a unclear boundary,solid,smooth surface,moderately active mass that estimated 0.4 cm at its greatest diameter in the left lobe of thyroid. Ultrasonography revealed a hypoechoic mass in the left lobe and Computed Tomography showed a 38 mm×25 mm×23 mm oval lesion with uniform density in the left lobe also. The surgical findings revealed tumor located in the inner side of left thyroid lobe near the isthmus,with unclear boundary. Pathological examination showed unclear boundaries between thyroid and tumor,the tumor cells attack into the muscle tissue,braided/ fascicles spindle shaped or star shaped myofibroblasts cells in the tumor area with myxedema inflammatory background and the lesion did not have any mitotic figures. Immunohistochemical analysis indicated that the spindle cells were positive for Vim,ACT,SMA,Bcl2 and ClyD1,and focal lesion histiocytes showed focal positive for CD68,CK and S-100,but negative for DES,Mgo,CD99,CD34,CD117,IgG4,ALK-1.The pathological diagnosis supports inflammatory myofibroblastic tumor of thyroid. Imaging and immunohistochemistry and others are useful in differential diagnosis.

Abstract
OBJECTIVE The purpose of this study was to investigate the efficacy and safety of haploidentical allogeneic hemopoietic stem cell transplantation (allo-HSCT) in severe aplastic anemia (SAA) and prophylaxis of complications involved. PATIENTS AND METHODS 8 patients with clinically diagnosed SAA (5 cases of SAA-I and 3 cases of SAA-II) were recruited, with the parents as the donors of hemopoietic stem cells. The conditioning regimen before HSCT included cyclophosphamide, fludarabine, pig anti-human lymphocyte immune globulin (p-ALG) and/or total body irradiation (TBI). The recipients received short-term methotrexate (MTX), mycophenolate mofetil (MMF), and cyclosporin A (CsA) for graft versus host disease (GVHD) prophylaxis. Subsequent to successful allo-HSCT, the hematopoietic reconstitution was observed, coupled with periodical surveillance of the chimerism rate, the occurrence, and severity of postoperative complications as infection, GVHD, veno-occlusive disease (VOD), hemorrhagic cystitis (HC), cytomegalovirus (CMV) as well as the long-term survival rate, etc. RESULTS We found that hematopoietic reconstruction was achieved in all of the 8 patients with the average time of 14.8d for absolute neutrophil count (ANC) > 0.5×109/L, and the average time of 15.0d for platelet count was more than 20×109/L. Follow-up for 1 month later revealed that DNA chimeric rate of donor cells was 95%-100%. The complications were aGVHD in 7 cases including 5 cases of grade I-II (62.5%), 1 case of grade III (12.5%) and 1 case of grade IV (12.5%), as well as chronic graft versus host disease (cGVHD) in 2 patients, including 1 case (12.5%) localized in the oral cavity and 1 case (12.5%) with extensive type cGVHD in the whole body skin. No VOD or HC was observed, and no transplantation-related death occurred at median following-up of 8.5 months (2 to 18 months). CONCLUSIONS Allo-HSCT is safe and effective in patients with SAA and has great clinical perspective.

Abstract
To identify the roles of ethylene in fruit development in Japanese pear Pyrus pyrifolia 'Niitaka', one of the non-climacteric genotypes, source-sink strength and fruit development during fruit expansion were investigated when ethephon was applied after a conventional gibberellic acid (GA) lanolin paste treatment on the pedicel. The results demonstrate that the conventional GA treatment during the early stage of fruit expansion resulted in larger fruit size and advanced fruit maturation, but pre-harvest foliar application of ethephon only advanced fruit maturation. However, pre-harvest foliar application of ethephon with a preceding conventional GA treatment during the early stage of fruit expansion dramatically improved fruit size and advanced fruit maturation over GA or ethephon alone. Moreover, the early foliar application of ethephon showed a better efficacy in increasing fruit size than the late spraying. A further study revealed that when ethephon was applied after the conventional GA treatment, it improved source-sink strength associated with leaf photosynthesis and the specific rate of [13C] accumulation in fruit, and also strengthened cell expansion more than did GA or ethephon alone.

Abstract
With the aim of gathering temporal trends on bacterial epidemiology and resistance from multiple laboratories in China, the CHINET surveillance system was organized in 2005. Antimicrobial susceptibility testing was carried out according to a unified protocol using the Kirby-Bauer method or automated systems. Results were analyzed according to Clinical and Laboratory Standards Institute (CLSI) 2014 definitions. Between 2005 and 2014, the number of bacterial isolates ranged between 22,774 and 84,572 annually. Rates of extended-spectrum β-lactamase production among Escherichia coli isolates were stable, between 51.7 and 55.8%. Resistance of E. coli and Klebsiella pneumoniae to amikacin, ciprofloxacin, piperacillin/tazobactam and cefoperazone/sulbactam decreased with time. Carbapenem resistance among K. pneumoniae isolates increased from 2.4 to 13.4%. Resistance of Pseudomonas aeruginosa strains against all of antimicrobial agents tested including imipenem and meropenem decreased with time. On the contrary, resistance of Acinetobacter baumannii strains to carbapenems increased from 31 to 66.7%. A marked decrease of methicillin resistance from 69% in 2005 to 44.6% in 2014 was observed for Staphylococcus aureus. Carbapenem resistance rates in K. pneumoniae and A. baumannii in China are high. Our results indicate the importance of bacterial surveillance studies.

Abstract
Ion transport peptide (ITP) and its alternatively spliced homologous ITP-like (ITPL) products play important roles in various insect developmental processes. We found for the first time that alternative 5' untranslated regions (5' UTRs) of ITPL (NilluITPLs-1, -2, -3 and -4) control spatiotemporal expression in the brown planthopper, Nilaparvata lugens, as demonstrated by reverse-transcription quantitative PCR. By using an alternative 5' UTR, NilluITPL-1 was expressed exclusively in the male reproductive system, resulting in the production of the NilluITPL seminal fluid protein. Interestingly, NilluITPLs-3 and -4 were expressed exclusively in the integument, indicating a specialized function for NilluITPL during ecdysis and eclosion. We investigated the functions of NilluITP and NilluITPL using RNA interference (RNAi). We did not observe apparent phenotypes when expression of NilluITPLs was suppressed. However, when NilluITP expression was suppressed, the insect exhibited melanism and failed wing expansion, indicating that NilluITP is a neuropeptide associated with wing expansion in addition to bursicon. Additionally, in contrast to bursicon, the insects showed increased melanism when NilluITP was eliminated by RNAi. Unlike previous studies of ITP/ITPL in other species, NilluITP was very important in the control of N. lugens postecdysial behaviours but was not critical during ecdysis. Thus, the functions of ITP and ITPL are more complex in insects than previously thought.

Abstract
To investigate the effects of carbomer eye drops (CED) during long-time wearing of overnight orthokeratology lens of adolescents with myopia, 260 teenagers with myopia treated in the Henan Provincial Peoples Hospital from June 2012 to August 2014 and followed-up for more than 2 years were enrolled. All the patients underwent regular fitting of orthokeratology lens. They were divided into a CED (Vidisic) group (130 cases, 260 eyes treated with CED) and rewetting drops (RD) (Baushe and Lomb) group (130 cases, 260 eyes treated with RD). The effects in the two groups were observed. The incidence of corneal epithelial defects one day, one week and one month after treatment of the CED group was lower than that of the RD group, and the difference was statistically significant (P less than 0.05); the tear break up time (TBUT) of the CED group was higher than that of the RD group at different time points, and the difference had statistical significance (P less than 0.05); the difference of the value of Schirmer I test between the two groups had no statistical significance (P>0.05). It is concluded that carbomer eye drops can stabilize tear film and protect and repair corneal epithelium during the wearing of orthokeratology lens.

Abstract
Bone marrow cells (BMC) are progenitors of bone, cartilage, skeletal tissue, the hematopoiesis-supporting stroma and adipocyte cells. BMCs have the potential to differentiate into neural cells, cardiac myocytes, liver hepatocytes, chondrocytes, renal, corneal, blood, and myogenic cells. The bone marrow cell cultures from stromal and mesenchymal cells are called multipotent adult progenitor cells (MAPCs). MAPCs can differentiate into mesenchymal cells, visceral mesoderm, neuroectoderm and endoderm in vitro. It has been shown that the stem cells derived from bone marrow cells (BMCs) can regenerate cardiac myocytes after myocardial infarction (MI). Adult bone marrow mesenchymal stem cells have the ability to regenerate neural cells. Neural stem/progenitor cells (NS/PC) are ideal for treating central nervous system (CNS) diseases, such as Alzheimer's, Parkinson's and Huntington disease. However, there are important ethical issues about the therapeutic use of stem cells. Neurons, cardiac myocytes, hepatocytes, renal cells, blood cells, chondrocytes and adipocytes regeneration from BMCs are very important in disease control. It is known that limbal epithelial stem cells in the cornea can repair the eye sight and remove symptoms of blindness. Stem cell therapy (SCT) is progressing well in animal models, but the use of SCT in human remains to be explored further.

Abstract
OBJECTIVE To explore the expression level of neuron-specific enolase (NSE), S100B and neuropeptide Y (NPY) in children with acute miliary tuberculosis and secondary tubercular meningitis. PATIENTS AND METHODS 28 children diagnosed with acute miliary tuberculosis and secondary tubercular meningitis were included into group A, 25 children diagnosed with pure acute miliary tuberculosis were included into group B and 23 children diagnosed with suspected meningitis were included into group C. The levels of NSE, S100B and NPY in cerebrospinal fluid and serum were detected. RESULTS The levels of NSE, S100B and NPY in cerebrospinal fluid and serum of group A were significantly higher than the levels in the other two groups, differences were statistically significant (p<0.05). A multifactor retrospective analysis suggested that secondary tubercular meningitis was significantly correlated with the high expression of S100B, NPY and NSE in cerebrospinal fluid and serum. CONCLUSIONS Early detection of the expression levels of NSE, S100B and NPY in cerebrospinal fluid and serum was of great value for the diagnosis of tubercular meningitis secondary to acute miliary tuberculosis.

Abstract
This paper aims to study the relationship between genetic susceptibility of tuberculosis and macrophage migration inhibitory factor (MIF) and provide theoretical basis and foundation for further studies on pathogenesis and treatment of tuberculosis. Enzyme Linked Immuno Sorbent Assay (ELISA) was applied to detect the difference of MIF protein expression level in peripheral serum of the test subjects, and analyze the difference of MIF protein expression levels of different genotypes and alleles at -794CATT locus and -173G/C locus. The results showed that MIF protein expression level in serum of patients in the tuberculosis group was higher than that of the healthy control group (p < 0.05). The MIF protein expression level of genotype (5/5+5/6+6/6) and (7/X+8/X) at -794CATT locus of the tuberculosis group was higher than that of the healthy control group (p < 0.05), and MIF protein expression level of genotype GG and (GC+CC) at -173G/C locus of the tuberculosis group was higher than that of the healthy control group (p < 0.05). Therefore, macrophage migration inhibitory factor is an important cell factor which plays a regulating role in the immune system, as it can inhibit macrophage migration and promote the gathering, infiltration and proliferation of macrophages at inflammatory sites. Furthermore, it can secrete some cell factors which play a central role in immunological regulation.
