Abstract
PURPOSE To create a reliable radiomic nomogram for the prediction of the International Society of Urological Pathology (ISUP) grading ≥ 3 prostate cancer (PCa) patients. METHODS patients with verified PCa were obtained from three different hospitals. The patients were divided into training, internal validation, and two external validation groups. A radiomic signature (rad-score) extracted from T2WI, diffusion-weighted imaging, and apparent diffusion coefficient (ADC) maps were constructed in the training cohort. Eight clinical features were performed to develop a clinical model using univariate and multivariate logistic regression. The combined model incorporated the radiomic signature and clinical model. The model's performance was assessed by the receiver operating characteristic (ROC) curve. RESULTS Rad-score, magnetic resonance imaging T-stage, and ADC value were significant predictors of ISUP ≥ 3 PCa. A nomogram of these three factors was shown to have greater diagnostic accuracy than using only the radiomic signature or clinical model alone. The area under the ROC curve was 0.85, 0.88, 0.81, 0.81 for the training, internal, and two external validation cohorts, respectively. In the stratified analysis based on the MR scanner model, the area under the ROC curve of predicting ISUP ≥ 3 PCa for GE, Siemens, and combined groups were 0.84, 0.83, and 0.84, respectively, in the combined training group and an internal validation group. CONCLUSIONS The proposed nomogram has the potential to predict the differentiation degree of ISUP PCa patients.

Abstract
BACKGROUND The Global COVID Vaccine Safety (GCoVS) Project, established in 2021 under the multinational Global Vaccine Data Network™ (GVDN®), facilitates comprehensive assessment of vaccine safety. This study aimed to evaluate the risk of adverse events of special interest (AESI) following COVID-19 vaccination from 10 sites across eight countries. METHODS Using a common protocol, this observational cohort study compared observed with expected rates of 13 selected AESI across neurological, haematological, and cardiac outcomes. Expected rates were obtained by participating sites using pre-COVID-19 vaccination healthcare data stratified by age and sex. Observed rates were reported from the same healthcare datasets since COVID-19 vaccination program rollout. AESI occurring up to 42 days following vaccination with mRNA (BNT162b2 and mRNA-1273) and adenovirus-vector (ChAdOx1) vaccines were included in the primary analysis. Risks were assessed using observed versus expected (OE) ratios with 95 % confidence intervals. Prioritised potential safety signals were those with lower bound of the 95 % confidence interval (LBCI) greater than 1.5. RESULTS Participants included 99,068,901 vaccinated individuals. In total, 183,559,462 doses of BNT162b2, 36,178,442 doses of mRNA-1273, and 23,093,399 doses of ChAdOx1 were administered across participating sites in the study period. Risk periods following homologous vaccination schedules contributed 23,168,335 person-years of follow-up. OE ratios with LBCI > 1.5 were observed for Guillain-Barré syndrome (2.49, 95 % CI: 2.15, 2.87) and cerebral venous sinus thrombosis (3.23, 95 % CI: 2.51, 4.09) following the first dose of ChAdOx1 vaccine. Acute disseminated encephalomyelitis showed an OE ratio of 3.78 (95 % CI: 1.52, 7.78) following the first dose of mRNA-1273 vaccine. The OE ratios for myocarditis and pericarditis following BNT162b2, mRNA-1273, and ChAdOx1 were significantly increased with LBCIs > 1.5. CONCLUSION This multi-country analysis confirmed pre-established safety signals for myocarditis, pericarditis, Guillain-Barré syndrome, and cerebral venous sinus thrombosis. Other potential safety signals that require further investigation were identified.

Abstract
BACKGROUND Adiponectin (APN) has exhibited ameliorating effects on non-alcoholic fatty liver disease (NAFLD). This study investigates the roles of APN and its regulatory molecules in hepatic stellate cell (HSC) activation and the progression of NAFLD. METHODS Mice were subjected to a high-fat diet (HFD) to establish NAFLD models. Liver tissue was examined for lipid metabolism, fibrosis, and inflammation. Mouse 3T3-L1 adipocytes were exposed to palmitic acid (PA) to mimic a high-fat environment. The conditioned medium (CM) from adipocytes was collected for the culture of isolated mouse HSCs. Gain- or loss-of-function studies of APN, nuclear receptor subfamily 2 group F member 2 (NR2F2), and STIP1 homology and U-box containing protein 1 (STUB1) were performed to analyze their roles in NAFLD and HSC activation in vivo and in vitro. RESULTS APN expression was poorly expressed in HFD-fed mice and PA-treated 3T3-L1 adipocytes, which was attributed to the transcription inhibition mediated by NR2F2. Silencing of NR2F2 restored the APN expression, ameliorating liver steatosis, fibrosis, and inflammatory cytokine infiltration in mouse livers and reducing HSC activation. Similarly, the NR2F2 silencing condition reduced HSC activation in vitro. However, these effects were counteracted by artificial APN silencing. STUB1 facilitated the ubiquitination and protein degradation of NR2F2, and its upregulation mitigated NAFLD-like symptoms in mice and HSC activation, effects reversed by the NR2F2 overexpression. CONCLUSION This study highlights the role of STUB1 in reducing HSC activation and alleviating NAFLD by attenuating NR2F2-mediated transcriptional repression of APN.

Abstract
Previous studies have found that miR-335 is highly expressed in type II diabetes mellitus (T2DM) models and is related to insulin secretion, but there are few studies on the regulatory effects of miR-335-3p on insulin resistance and macrophage polarization in T2DM patients. This study aims to explore the effects of miR-335-3p on insulin resistance and macrophage polarization in T2DM patients. Blood glucose (insulin tolerance tests, glucose tolerance tests) and body weight of the T2DM model were measured; macrophages from adipose tissue were isolated and cultured, and the number of macrophages was detected by F4/80 immunofluorescence assay; the Real-time quantitative polymerase chain reaction (qPCR) assay and Western blot assay were used to detect the miR-335-3p expression levels, insulin-like growth factor 1 (IGF-1), M1-polarizing genes (inducible nitric oxide synthase [iNOS] and TNF-α) as well as M2-polarizing genes (IL-10 and ARG-1). The targeting link between miR-335-3p and IGF-1 was confirmed using bioinformatics and dual luciferase assay. The results showed that miR-335-3p expression level in adipose tissue of the T2DM model was significantly decreased, and the mice's body weight and blood glucose levels dropped considerably, miR-335-3p inhibited the number of macrophages, inhibiting the iNOS and TNF-α relative mRNA expression levels, and up-regulated the IL-10 and ARG-1 relative mRNA expression levels, miR-335-3p negatively regulated target gene IGF-1, IGF-1 significantly increased the iNOS and TNF-α mRNA and protein expression levels, decreasing the IL-10 and ARG-1 mRNA and protein expression levels, indicating that miR-335-3p could affect the T2DM process by regulating macrophage polarization via IGF-1.

Abstract
BACKGROUND Patients often experience severe pain after scoliosis correction surgery. Esketamine and dexmedetomidine each improves analgesia but can produce side-effects. We therefore tested the hypothesis that a mini-dose esketamine-dexmedetomidine combination safely improves analgesia. METHODS Two hundred male and female adults having scoliosis correction surgery were randomised to patient-controlled sufentanil analgesia (4 μg kg-1 in normal saline) with either a combined supplement (esketamine 0.25 mg ml-1 and dexmedetomidine 1 μg ml-1) or placebo. The primary outcome was the incidence of moderate-to-severe pain within 72 h, defined as a numeric rating scale (NRS: 0=no pain and 10=worst pain) score ≥4 at any of seven time points. Amongst secondary outcomes, subjective sleep quality was assessed with an NRS score (0=best sleep and 10=worst sleep) for the first five postoperative nights. RESULTS There were 199 subjects included in the intention-to-treat analysis. Mean infusion rates were 5.5 μg kg-1 h-1 for esketamine and 0.02 μg kg-1 h-1 for dexmedetomidine. The primary outcome incidence was lower with the combined supplement (65.7% [65/99]) than with placebo (86.0% [86/100]; relative risk 0.76; 95% confidence interval: 0.65-0.90; P=0.001). Subjects given the combined supplement had lower pain intensity at rest at five time points (median difference -1 point; P≤0.005), lower pain intensity with movement at six time points (median difference -1 point; P≤0.001), and better subjective sleep quality for the first 5 postoperative nights (median difference -2 to -1 points; P<0.001). Adverse events did not differ between groups. CONCLUSIONS The mini-dose esketamine-dexmedetomidine combination safely improved analgesia and subjective sleep quality after scoliosis correction surgery. CLINICAL TRIAL REGISTRATION NCT04791059.

Abstract
Objective To explore the characteristics of renal artery variation in patients with renal cell carcinoma and to evaluate the predicting value of accessory renal artery in the pathological grading of renal cell carcinoma. Methods The clinicopathological data of patients with clear cell renal cell carcinoma diagnosed in the Department of Urology of the First Hospital of Shanxi Medical University from September 2019 to March 2023 were retrospectively analyzed. All patients underwent visual three-dimensional model reconstruction from computed tomography images. All kidneys were divided into two groups: the affected kidney and the healthy kidney, and the incidence of renal artery variation in the two groups was analyzed. Then, according to the existence of accessory renal artery in the affected kidney, the patients were divided into two groups, and the relationship between accessory renal artery and clinicopathological features of patients with clear cell renal cell carcinoma was analyzed. Finally, univariate and multivariate logistic regression analyses were performed to determine the predictors of Fuhrman grading of clear cell renal cell carcinoma, and the predictive ability of the model was evaluated by the receiver operating characteristic curve. Results The incidence of renal artery variation and accessory renal artery in the affected kidney was significantly higher than them in the healthy kidney. The patients with accessory renal artery in the affected kidney had larger tumor maximum diameter, higher Fuhrman grade and more exophytic growth. The presence of accessory renal artery on the affected kidney and the maximum diameter of tumor are independent predictors of high-grade renal cell carcinoma. The receiver operating characteristic curve suggests that the model has a good predictive ability. Conclusion The existence of accessory renal artery on the affected kidney may be related to the occurrence and development of clear cell renal cell carcinoma, and can better predict Fuhrman grade of clear cell renal cell carcinoma. The finding provides a reference for the future diagnostic evaluation of RCC, and provides a new direction for the study of the pathogenesis of RCC.

Abstract
BACKGROUND Little is known about the association between the preoperative low-density lipoprotein cholesterol (LDL-C) level and prognosis in patients with renal cell carcinoma (RCC) after nephrectomy, and its prognostic value needs to be elucidated. METHODS The clinical and follow-up data of 737 RCC patients who underwent nephrectomy were retrospectively analyzed. The optimal cut-off LDL-C level was determined using X-tile, and then patients were divided into low and high LDL-C groups. The association between LDL-C levels and survival of RCC patients was assessed using the Kaplan-Meier method and Cox regression analysis. RESULTS The optimal cut-off LDL-C level was 1.93 mmol/L, and patients were divided into the low (≤ 1.93 mmol/L) and high LDL-C (> 1.93 mmol/L) groups. The Kaplan-Meier analysis showed that patients in the low LDL-C group had significantly shorter overall survival (OS), cancer-specific survival (CSS) and recurrence-free survival (RFS) than those in the high LDL-C group (P = 0.001, P = 0.001, and P = 0.003, respectively). The COX univariate analysis showed that the preoperative LDL-C level was closely associated with OS, CSS, and RFS in RCC patients (P = 0.002, P = 0.003, and P = 0.005, respectively). The multivariate analysis showed that the preoperative LDL-C level was an independent factor for predicting survival (OS, CSS and RFS) in RCC patients after nephrectomy. The low preoperative LDL-C levels predicted worse OS (hazard ratio [HR]: 2.337; 95% confidence interval [CI]: 1.192-4.581; P = 0.013), CSS (HR: 3.347; 95% CI: 1.515-7.392; P = 0.003), and RFS (HR: 2.207; 95% CI: 1.178-4.132; P = 0.013). CONCLUSIONS The preoperative LDL-C level is an independent factor for the prognosis of RCC patients after nephrectomy, and low preoperative LDL-C levels predict worse survival (OS, CSS, and RFS).

Abstract
BACKGROUND To analyze the top 100 most-cited articles on renal cell carcinoma (RCC) using bibliometric methods based on the Web of Science core collection database and to explore the research status, hotspots, and emerging trends in RCC. METHODS The literature on RCC was searched in the Web of Science core collection database using a specific search strategy, and the types of literature were limited to articles and reviews, with no restrictions to language and publication date. The top 100 articles with the highest number of citations were extracted after the manual screening. The publication year, the number of citations, authors, country, institution, journal, and keywords of these articles were collected and analyzed. Descriptive statistics and visual analysis were performed using Microsoft Excel, VOSviewer, CiteSpace, R, and SPSS. RESULTS The number of citations of the top 100 articles varied from 541 to 4530, with a median citation count of 807.5, and the citation rates ranged from 13.8 to 448.4 citations per year. Motzer RJ (n = 22), Escudier B (n = 13), Rini BI (n = 13), and Hutson TE (n = 11) were major contributors to this research area, with Motzer RJ publishing 16 articles as the first author. The US (n = 73), France (n = 5), Canada (n = 4), and Sweden (n = 4) were the leading countries for RCC studies. MEMORIAL SLOAN KETTERING CANCER CENTER (n = 22) was the institution with the highest number of publications. These 100 articles were derived from 24 journals, and the New England Journal of Medicine had the largest number of articles published (n = 18, impact factor = 91.245). The keyword co-occurrence network analysis showed that research hotspots in this field included molecular mechanisms of RCC development and progression, surgical treatment, targeted drug-related clinical trials, and immunotherapy. CONCLUSION We analyzed the top 100 articles with the highest number of citations in the field of RCC and identified the influential authors, countries, institutions, and journals in this field. This study also presented the current research status, hotspots, and future trends in RCC.

Abstract
BACKGROUND The association between preoperative cognitive impairment, postoperative pain, and postoperative delirium in older patients after noncardiac surgery is not known. METHODS This was a secondary analysis of datasets from three previous studies. Patients aged ≥55 yr who underwent elective noncardiac surgery were enrolled. Preoperative cognitive impairment was defined as Mini-Mental State Examination <27. Pain intensity with movement was assessed using an 11-point numeric rating scale at 12-h intervals during the first 72 h after surgery; time-weighted average (TWA) pain score was calculated. Primary outcome was the occurrence of delirium within the first 5 postoperative days. Mediation analysis was used to investigate the relationships between cognitive impairment, pain score, and delirium. RESULTS A total of 1497 patients were included. Prevalence of preoperative cognitive impairment was 40.3% (603/1497). Patients with cognitive impairment suffered higher TWA pain score within 72 h (4 [3-5] vs 3 [2-5], P=0.004) and more delirium within 5 days (12.9% [78/603] vs 4.9% [44/894], P<0.001) when compared with those without. Total and direct associations between cognitive impairment and delirium were (adjusted β) 8.3% (95% confidence interval [CI], 4.8-12.0%; P<0.001) and 7.8% (95% CI, 4.4-12.0%; P<0.001), respectively. A significant indirect association with acute pain was observed between cognitive impairment and delirium (adjusted β=0.4%; 95% CI, 0.1-1.0%; P=0.006), accounting for 4.9% of the total effect. CONCLUSIONS The association between preoperative cognitive impairment and delirium is significantly mediated by acute pain in patients after noncardiac surgery. Considering the small effect size, clinical significance of this mediation effect requires further investigation.

Abstract
BACKGROUND Post-operative pneumonia (POP) is a common complication of lung cancer surgery, and muscular tissue oxygenation is a root cause of post-operative complications. However, the association between muscular tissue desaturation and POP in patients receiving lung cancer surgery has not been specifically studied. This study aimed to investigate the potential use of intra-operative muscular tissue desaturation as a predictor of POP in patients undergoing lung cancer surgery. METHODS This cohort study enrolled patients (≥55 years) who had undergone lobectomy with one-lung ventilation. Muscular tissue oxygen saturation (SmtO 2 ) was monitored in the forearm (over the brachioradialis muscle) and upper thigh (over the quadriceps) using a tissue oximeter. The minimum SmtO 2 was the lowest intra-operative measurement at any time point. Muscular tissue desaturation was defined as a minimum baseline SmtO 2 of <80% for >15 s. The area under or above the threshold was the product of the magnitude and time of desaturation. The primary outcome was the association between intra-operative muscular tissue desaturation and POP within seven post-operative days using multivariable logistic regression. The secondary outcome was the correlation between SmtO 2 in the forearm and that in the thigh. RESULTS We enrolled 174 patients. The overall incidence of muscular desaturation (defined as SmtO 2 < 80% in the forearm at baseline) was approximately 47.1% (82/174). The patients with muscular desaturation had a higher incidence of pneumonia than those without desaturation (28.0% [23/82] vs. 12.0% [11/92]; P = 0.008). The multivariable analysis revealed that muscular desaturation was associated with an increased risk of pneumonia (odds ratio: 2.995, 95% confidence interval: 1.080-8.310, P = 0.035) after adjusting for age, American Society of Anesthesiologists status, Assess Respiratory Risk in Surgical Patients in Catalonia score, smoking, use of peripheral nerve block, propofol, and study center. CONCLUSION Muscular tissue desaturation, defined as a baseline SmtO 2 < 80% in the forearm, may be associated with an increased risk of POP. TRIAL REGISTRATION No. ChiCTR-ROC-17012627.

Abstract
Objective: To compare oxytocin combined with ergometrine with oxytocin alone in terms of primary prophylaxis for postpartum hemorrhage (PPH) at the time of cesarean section (CS). Methods: This was a multicenter double-blind randomized controlled interventional study comparing ergometrine combined with oxytocin and oxytocin alone administered at CS. From December 2018 to November 2019, a total of 298 parturients were enrolled in 16 hospitals nationwide. They were randomly divided into experimental group (ergometrine intra-myometrial injection following oxytocin intravenously; 148 cases) and control group (oxytocin intra-myometrial injection following oxytocin intravenously; 150 cases) according to 1∶1 random allocation. The following indexes were compared between the two groups: (1) main index: blood loss 2 hours (h) after delivery; (2) secondary indicators: postpartum blood loss at 6 h and 24 h, placental retention time, incidence of PPH, the proportion of additional use of uterine contraction drugs, hemostatic drugs or other hemostatic measures at 2 h and 24 h after delivery, the proportion requiring blood transfusion, and the proportion of prolonged hospital stay due to poor uterine involution; (3) safety indicators: nausea, vomiting, dizziness and other adverse reactions, and blood pressure at each time point of administration. Results: (1) The blood loss at 2 h after delivery in the experimental group [(402±18) ml] was less than that in the control group [(505±18) ml], and the difference was statistically significant (P<0.05). (2) The blood loss at 6 h and 24 h after delivery in the experimental group were less than those in the control group, and the differences were statistically significant (all P<0.05). There were no significant differences between the two groups in the incidence of PPH, the proportion of additional use of uterine contraction drugs, hemostatic drugs or other hemostatic measures at 2 h and 24 h after delivery, the proportion requiring blood transfusion, and the proportion of prolonged hospital stay due to poor uterine involution (all P>0.05). (3) Adverse reactions occurred in 2 cases (1.4%, 2/148) in the experimental group and 1 case (0.7%, 1/150) in the control group. There was no significant difference between the two groups (P>0.05). The systolic blood pressure within 2.0 h and diastolic blood pressure within 1.5 h of drug administration in the experimental group were higher than those in the control group, and the differences were statistically significant (P<0.05), but the blood pressure of the two groups were in the normal range. Conclusion: The use of ergometrine injection in CS could reduce the amount of PPH, which is safe and feasible.

Abstract
Objective: To evaluate the quality of life and influencing factors of patients with herpes zoster (HZ) seen in hospitals. Methods: Based on Zoster Brief Pain Inventory (ZBPI) and Five-level EuroQol Five-dimensional Questionnaire (EQ-5D-5L), a cross-sectional survey was conducted to evaluate the pain severity and quality of life of 332 HZ cases seen in 22 hospitals of Lu'an City (Anhui Province), Zibo City (Shandong Province) and Tongchuan City (Shaanxi Province) from October to December 2021. The censored least absolute deviations (CLAD) model was used to analyze the related factors affecting the changes of patients' health utility values. Results: The 45.5% of 332 HZ cases were male. The median (Q1,Q3) age was 59 (50, 68) years. 59.64% of them assessed by ZBPI had moderate to severe pain in the past 24 hours (worst pain score≥5), and that of PHN cases was 84.8%(39/46). 77.7% (258/332), 77.4% (257/332) and 74.1% (246/332) of all patients reported that pain interfered with sleep, mood and general activities, respectively. Aging [β40-49y (95%CI)=-0.11 (-0.15, -0.08); β50-59y (95%CI)=-0.03 (-0.05, 0.00); β60-69y (95%CI)=-0.09 (-0.12, -0.06); β70-90y(95%CI)=-0.16 (-0.19, -0.12)], working status (unemployed) [βfarmer (95%CI)=0.15 (0.13, 0.18); βretirees(95%CI)=0.21 (0.18, 0.24); βemployee (95%CI)=0.13 (0.10, 0.16) ], complications[βPHN (95%CI)=-0.08 (-0.13, -0.04); βother complications (95%CI)=-0.12 (-0.15, -0.08)], within 30 days after onset [β(95%CI)=-0.01 (-0.03, 0.01)] and treatment [βother complications (95%CI)=-0.09 (-0.11, -0.06)] were related factors for the decline of health utility value (all P values <0.05). Conclusions: More than half of the patients with HZ had moderate to severe pain in the past 24 hours, which had a serious negative impact on the physical and mental health of the patients. Elderly patients, acute patients and patients with complications had lower health utility values and worse health status. We suggest that eligible people be vaccinated with HZ vaccine as soon as possible.

Abstract
BACKGROUND Vulvovaginal candidiasis (VVC) is a public health issue worldwide. Little is known of the optimal treatment of recurrent VVC (RVVC) has not been established. OBJECTIVE Through the in vitro antifungal susceptibility profiling of VVC isolates, we hope to foster significant improvements in the control and treatment of this disease. METHODS Candida isolates from VVC patients were collected from 12 hospitals in 10 cities across China. Species were identified by phenotype analysis and DNA sequencing. Species were identified by phenotype analysis and DNA sequencing. Susceptibilities to 11 drugs were determined by Clinical and Laboratory Standards Institute broth microdilution. RESULTS 543 strains were isolated from those VVC patients enrolled in this study, of which, 15.7% were from RVVC. The most commonly identified species was C. albicans (460, 84.71%), and the most commonly non-albicans Candida spp. (NAC) was C. glabrata (47, 8.66%). NAC also included C. Krusei, Meyerozyma Guillermondii, Meyerozyma Caribbica, C. Tropicalis, C. Parapsilosis, and C. Nivariensis. Most C. albicans isolates were susceptible to caspofungin (99.8%), followed by fluconazole (92%) and voriconazole (82.6%). The proportion of C. albicans strains with wild type (WT) MICs that were susceptible to amphotericin B and caspofungin were 98%, followed by posaconazole at 95%, itraconazole at 86%, fluconazole at 74% and voriconazole at 54%. The fluconazole MICs for C. albicans were lower than those for NAC (P < 0.05), while the itraconazole MICs showing no significant difference (P > 0.05). The susceptible rate of uncomplicated VVC to fluconazole was 92%. The proportion of WT strains to fluconazole in RVVC was much lower than that in other types of VVC (67 vs. 77%, P < 0.05). However, the proportions of WT strains to itraconazole in RVVC was over 85%, which was much higher than that to fluconazole (87 vs. 67%, P < 0.05). CONCLUSIONS C. albicans was still the predominant pathogen for VVC in China, while C. glabrata was the main species in NAC. Fluconazole could still be used as an empirical treatment for uncomplicated VVC. However, fluconazole may not be the first choice for the therapy of RVVC. In such cases, itraconazole appears to be the more appropriate treatment. As for VVC caused by NAC, nonfluconazole drugs, such as itraconazole, may be a good choice.

Abstract
BACKGROUND Sperm granuloma is a rare disease in clinical andrology and its incidence is still unclear worldwide. According to the existing literature, sperm granuloma often occurs unilaterally. Clinical and ultrasound features are similar to epididymal tuberculosis, chronic epididymitis and other diseases. Sperm granuloma is usually diagnosed based on postoperative histopathological and immunohistochemical examination.
CASE SUMMARY A 46-year-old man was admitted to the hospital due to the presence of a left scrotal mass for 3 mo and aggravation of pain for 1 wk. The lesions at both sites were surgically resected. Postoperative pathological examination showed that the left spermatic cord mass and the right epididymal mass were consistent with sperm granuloma. The sperm granulomas then recurred 3 mo after surgery. There is little change in the local mass so far.
CONCLUSION The case report is helpful for our understanding of this disease. In clinical diagnosis, it should be distinguished from epididymal tuberculosis, chronic epididymitis and other diseases. Color Doppler ultrasound can be used as a preferred examination method but postoperative pathological examination is still needed for diagnosis.

Abstract
Vulvovaginal candidiasis (VVC), which is most frequently caused by Candida albicans, is a common problem worldwide. Despite the fact that extensive epidemiological studies have been performed, the cause of recurrent VVC (RVVC) remains uncertain. The aims of this work were to compare the genotypes of C. albicans strains causing different conditions of VVC, and explore the relationship between the drug resistance and genotype of C. albicans strains. In our study, we collected 649 independent strains from VVC patients in China. Isolates were tested for in vitro susceptibility to fluconazole, itraconazole, voriconazole, amphotericin B and caspofungin in accordance with the Clinical Laboratory Standards Institute (CLSI) document M27-A3. Genotyping was performed using PCR targeting specific CAI locus marker. C. albicans is the main pathogen of VVC, but the proportion of non-candida albicans (NAC) infection is also increasing, and we also found increased cases of mixed infection. Some C. albicans are resistant to multiple drugs. The strains with the genotypes including 16-16, 18-18 and 22-22 was likely to be the dominant genotype of uncomplicated VVC (p < 0.05). The genotypes of complicated VVC are mainly distributed in 30-45, 33-45, 32-46 and 39-45. Strains of 30-45, 32-45, 30-47 and 30-46 genotypes showed resistance to fluconazole, itraconazole, voriconazole and amphotericin B respectively. Our work suggests that the dominant genotypes with higher repeat number of C. albicans strains were more prevalent in patients with RVVC and drug-resistant strains, however, strains with uncomplicated VVC were more likely to distribute in homozygous. Identification of specific genotypes that correlate with different conditions of VVC and drug resistant is also of diagnostic and therapeutic significance.

Abstract
Objective: Charcot-Marie-Tooth disease (CMT) comprises a group of clinically and genetically heterogeneous inherited neuropathies with an estimated prevalence of 1 in 2500. This study aimed to analyze the clinical and mutational characteristics of Chinese CMT patients with MFN2, BSCL2 and LRSAM1 variants. Methods: In this study, genetic analysis was performed in 206 Chinese patients at Chinese PLA General Hospital from December 2012 to March 2020 with clinical diagnosis of CMT, and reported variants of MFN2, BSCL2 and LRSAM1 related to CMT2. Results: We reported ten MFN2 mutations in ten unrelated patients (7 male, 3 female), two of whom had positive family history. Three novel mutations were detected including c.475-2A>G (splicing); c.687dupA (p.E230Rfs*16) and c.558dupT (p.S186fs). We reported three BSCL2 mutations of four unrelated patients, including c.461C>G (p.S154W), c.461C>T(p.S154L), and novel variants of c.1309G>C (p.A437P) and c.845C>T (p.A282V). Furthermore, two novel variants of LRSAM1, including c.1930G>T (p.G644C) and c.1178T>A (p.L393Q) were detected in two unrelated patients. Conclusion: Mutational spectrum of MFN2-, BSCL2-and LRSAM1-related CMT disease is expanded with the identification of novel variants in Chinese patients.

Abstract
Hepatitis B virus (HBV) infection remains a major health problem worldwide, and the current antiviral therapy, including nucleoside analogs, cannot achieve life-long cure, and clarification of antiviral host immunity is necessary for eradication. Here, we found that a clathrin-binding membrane protein epsin3 (EPN3) negatively regulates the expression of HBV RNA. EPN3 expression was induced by transfection of an HBV replicon plasmid, and reduced HBV-RNA level in hepatic cell lines and murine livers hydrodynamically injected with the HBV replicon plasmid. Viral RNA reduction by EPN3 was dependent on transcription, and independent from epsilon structure of viral RNA. Viral RNA reduction by overexpression of p53 or IFN-α treatment, was attenuated by knockdown of EPN3, suggesting its role downstream of IFN-α and p53. Taken together, this study demonstrates the anti-HBV role of EPN3. The mechanism how it decreases HBV transcription is discussed.

Abstract
The self-assembly of DNA-coated colloids into highly-ordered structures offers great promise for advanced optical materials. However, control of disorder, defects, melting, and crystal growth is hindered by the lack of a microscopic understanding of DNA-mediated colloidal interactions. Here we use total internal reflection microscopy to measure in situ the interaction potential between DNA-coated colloids with nanometer resolution and the macroscopic melting behavior. The range and strength of the interaction are measured and linked to key material design parameters, including DNA sequence, polymer length, grafting density, and complementary fraction. We present a first-principles model that screens and combines existing theories into one coherent framework and quantitatively reproduces our experimental data without fitting parameters over a wide range of DNA ligand designs. Our theory identifies a subtle competition between DNA binding and steric repulsion and accurately predicts adhesion and melting at a molecular level. Combining experimental and theoretical results, our work provides a quantitative and predictive approach for guiding material design with DNA-nanotechnology and can be further extended to a diversity of colloidal and biological systems. A quantitative prediction of DNA-mediated interactions between colloids is crucial to the design of colloidal structures for optical applications. Cui et al. measure the interaction potential with nanometer resolution and propose a theory to accurately predict adhesion and melting at a molecular level.

Abstract
BACKGROUND AND OBJECTIVE Type 2 diabetes mellitus (T2DM) is an endocrine disorder with pancreatic β cell dysfunction and/or reduced insulin sensitivity. IGF-1 is critically involved in pancreatic β cell growth, differentiation, and insulin secretion. Insulin-mediated IRS1/PI3K/Akt/FOXO1 signaling has been proved to be closely associated with pancreatic β cell function, hepatic glucose metabolism, and the development of T2DM. This present work was designed to demonstrate the protective role of IGF-1 against pancreatic β cell dysfunction and to probe into the underlying mechanisms. METHODS Herein, cell viability, cell apoptosis, insulin secretion, oxidative stress, and glycolysis in STZ-treated INS-1 cells were measured, so as to determine the biological function of IGF-1 against pancreatic β cell dysfunction in T2DM. Additionally, whether IGF-1 could activate IRS1/PI3K/Akt/FOXO1 signaling pathway to manipulate the progression of T2DM was also investigated. RESULTS It was discovered that IGF-1 treatment enhanced the viability and suppressed the apoptosis of STZ-treated INS-1 cells. Besides, IGF-1 treatment augmented insulin secretion of INS-1 cells in response to STZ. Moreover, IGF-1 exerted protective role against oxidative damage and displayed inhibitory effect on glycolysis in STZ-treated INS-1 cells. Mechanistically, IGF-1 treatment markedly boosted the activation of IRS1/PI3K/Akt/FOXO1 pathway. Furthermore, treatment with AG1024 (an inhibitor of IGF-1R) partially abolished the actions of IGF-1 on cell viability, cell apoptosis, insulin secretion, oxidative stress, and glycolysis in STZ-treated INS-1 cells. CONCLUSION To conclude, IGF-1 could improve the viability and inhibit the apoptosis of STZ-treated pancreatic β cells, induce insulin secretion, alleviate oxidative damage, as well as arrest glycolysis by activating IRS1/PI3K/Akt/FOXO1 pathway.

Abstract
Total internal reflection microscopy (TIRM) measures changes in the distance between a colloidal particle and a transparent substrate by measuring the scattering intensity of the particle illuminated by an evanescent wave. From the distribution of the recorded separation distances, the height-dependent effective potential φ(z) between the colloidal particle and the substrate can be measured. In this work, we show that spatial resolution with which TIRM can measure φ(z) is limited by the photon counting statistics of the scattered laser light. We develop a model to evaluate the effect of photon counting statistics on different potential profiles using Brownian dynamics simulations and experiments. Our results show that the effect of photon counting statistics depends on spatial gradients ∂φ/∂z of the potential, with the result that sharp features tend to be significantly blurred. We further establish the critical role of photon counting statistics and the intensity integration time τ in TIRM measurements, which is a trade-off between narrowing the width of the photon counting distribution and capturing the instantaneous position of the probe particle.

Abstract
BACKGROUND Vulvovaginal candidiasis (VVC) is frequent in women of reproductive age, but very limited data are available on the epidemiology in cases of VVC in China. OBJECTIVES The current study has been conducted to reveal the prevalence, species distribution of yeast causing VVC and molecular genetics of Candida albicans in China. METHODS Vaginal swabs were collected from 543 VVC outpatients recruited in 12 hospitals in China between September 2017 and March 2018. They were preliminarily incubated on Sabouraud dextrose agar and then positive subjects of which were then transmitted to our institute for further identification. CHROMagar™ was used to isolate Candida species, and all isolates were finally identified by DNA sequencing. Multilocus sequence typing (MLST) was used to analyse phylogenetic relationships of the various C. albicans isolates. RESULTS Eleven different yeast species were identified in 543 isolates, among which C. albicans (84.7%) was the most frequent, followed by C. glabrata (8.7%). We obtained 117 unique diploid sequence types from 451 clinical C. albicans isolates and 92 isolates (20.4%) belonged to a New Clade. All the strains appearing in the New Clade were from northern China and they were isolated from non-recurrent VVC. CONCLUSIONS Our findings suggest that C. albicans are still the main cause of VVC in China and the majority of C. albicans isolates belongs to Clade 1 with DST 79 and DST 45 being two most common. Moreover, the New Clade revealed in our study seems to be specific to northern China.

Abstract
Diabetes mellitus (DM) characterised by pancreatic β-cell dysfunction and insulin resistance is already prevalent worldwide, and the complications of DM increased the mortality of diabetic patients. More and more reports showed that long non-coding RNA (lncRNA) plays key
roles in DM, and in this study we explored the effect of long non-coding RNA SNHG14 (SNHG14) in DM. Quantitative reverse transcription PCR (qRT-PCR) was used to analyze the expression of SNHG14 and microRNA (miR)-206 in peripheral blood from 60 pairs of healthy and DM samples. Then the effect
of SNHG14 on the insulin secretion of pancreatic β-cells was investigated. Moreover, the effects of SNHG14 on the viability and apoptosis of pancreatic β-cells were determined by 3-(4, 5)-dimethylthiahiazo (-z-y1)-3, 5-di- phenytetrazoliumromide (MTT) assay and flow
cytometry (FCM) respectively using INS-1 cells transfected with SNHG14-plasmid and/or miR-206 mimic. Bioinformatics and Daul luciferase reporter assay were used to confirm the direct target of miR-206. Our data showed that SNHG14 level was decreased but miR-206 was increased significantly
in the peripheral blood of DM patients. Furthermore, over-expression of SNHG14 enhanced insulin secretion and cell viability but inhibited apoptosis of pancreatic β-cells, whereas, miR-206 over-expression reversed these effects. In addition, insulin-like growth factor-1 (IGF1)
was proved to be regulated by miR-206 negatively and over-expression of SNHG14 increased the expression of IGF1 and IGF1R in pancreatic β-cells. In conclusion, we found that SNHG14 was significantly down-regulated in DM patients, and SNHG14/miR-206/IGF1 may serve as a potential
candidate for the clinical target of DM.

Abstract
Background: Diabetes mellitus (DM), a common metabolic disease, is featured with chronic hyperglycemia and dysfunction of pancreatic β-cells. Various evidences suggested that microRNAs (miR-NAs) were tightly related to the occurrence of DM and can be regulated in
pancreatic-β-cells. However, whether or not microRNA-206 (miR-206) affects the development of DM and the specific mechanisms remains elusive. We designed this study to clarify the function and associated potential mechanism of miR-206 in pancreatic β-cells via the insulin-like
growth factor 1 reporter (IGF1R)/phosphatidylinositide 3-kinase (PI3 K)/protein kinase B (AKT) signaling pathway, which may provide novel diagnostic or therapies for DM. Methods: In this research, the levels of miR-206 and insulin-like growth factor 1 (IGF1) were assessed using quantitative
reverse transcription PCR (qRT-PCR) and/or Western bolt assay. Bioinformatics and dual luciferase reporter assays were adopted to illustrate the relationship between miR-206 and IGF1. INS-1 cells were stimulated with stimulatory glucose (16.7 mM) or basal glucose (3.3 mM) for 1 h, and the
insulin content was examined by enzyme linked immunosorbent assay (ELISA). Besides, 3-(4,5)-dimethylthiahiazo (-z-y1)-3,5-di-phenytetrazoliumromide (MTT) assay and flow cytometry (FCM) analysis were conducted to determine the INS1 cell viability and apoptosis. Furthermore, the related proteins
in IGF1R/PI3 K/AKT pathway (IGF1R, p-AKT and AKT) were tested using Western blot assay, respectively. Results: Our data suggested that miR-206 level in the blood samples of DM patients was higher than that in healthy donors. IGF1 was identified as a direct target of miR-206. Moreover,
we found that miR-206 negatively regulated IGF1 expression in INS-1 cells. It was also confirmed that miR-206 inhibitor led to an increase of total insulin content, an increase of INS-1 cell viability and a decrease of cell apoptosis. Accordingly, miR-206 inhibitor significantly enhanced IGF1R
and p-AKT protein expression in INS-1 cells. All these findings were reversed by IGF1-siRNA co-transfection. Conclusion: Our observations clearly demonstrated that miR-206 could regulate the IGF1R/PI3K/AKT pathway by targeting IGF1, thereby regulating the cell viability of pancreatic
β cells and the ability of pancreatic β cells to secrete insulin.

Abstract
Polymer networks consisting of a mixture of chemical and physical cross-links are known to exhibit complex time-dependent behaviour due to the kinetics of bond association and dissociation. In this article, we highlight and compare two recent physically based constitutive models that describe the nonlinear viscoelastic behaviour of such transient networks. These two models are developed independently by two groups of researchers using different mathematical formulations. Here, we show that this difference can be attributed to different viewpoints: Lagrangian versus Eulerian. We establish the equivalence of the two models under the special situation where chains obey Gaussian statistics and steady-state bond dynamics. We provide experimental data demonstrating that both models can accurately predict the time-dependent uniaxial behaviour of a poly(vinylalcohol) dual cross-link hydrogel. We review the advantages and disadvantages of both approaches in applications and close by discussing a list of open challenges and questions regarding the mathematical modelling of soft, viscoelastic networks.

Abstract
Background: The objective of the research was to investigate the roles of miR-4458 in the regulation of insulin resistance in hepatic cells and to explore the underlying molecular mechanisms. Methods: The blood samples were collected from the T2D patients and the health
controls, and the liver tissues were collected from the DM and control rats. The relationship between IGF1R and miR-4458 was predicted by TargetScan and verified by the dual luciferase reporter gene system. qRT-PCR was used to measure the mRNA expression of miR-4458, IGF1R, G6Pase and PEPCK.
The protein expression of IGF1R, p-AKT and AKT were measured by Western blot analysis. The rat insulin ELISA Kit and glucose Uptake Colorimteric Assay Kit were used to determine the level of serum insulin and the glucose uptake. Results: miR-4458 was high expressed in T2D patients.
We predicted and verified that IGF1R was a direct target of miR-4458, and the mRNA expression of IGF1R was reduced in type 2 diabetes patients. We established the diabetes model (DM) and IR HepG2 cell model, and found that the blood glucose and serum insulin levels were significantly elevated
in the DM group. miR-4458 expression was up-regulated, while the expression of IGF1R and p-AKT, and p-AKT/AKT ratio were reduced in the DM group and IR HepG2 cell model. miR-4458 inhibitor and IGF1R-siRNA significantly decreased the expression of miR-4458 and IGF1R respectively. In comparison
with IR+inhibitor control group, miR-4458 inhibitor increased 2-DG6P content, IGF1R expression, p-AKT expression and p-AKT/AKT ratio, reduced the expression of G6Pase and PEPCK, and all the effects were reversed by down-regulating IGF1R. Conclusion: miR-4458 regulated the insulin resistance
in hepatic cells by regulating the IGF1R/PI3K/AKT signal pathway, which will be a potential target for the treatment of diabetes.

Abstract
BACKGROUND The association between cerebral desaturation and postoperative delirium in thoracotomy with one-lung ventilation (OLV) has not been specifically studied. METHODS A prospective observational study performed in thoracic surgical patients. Cerebral tissue oxygen saturation (Scto2) was monitored on the left and right foreheads using a near-infrared spectroscopy oximeter. Baseline Scto2 was measured with patients awake and breathing room air. The minimum Scto2 was the lowest measurement at any time during surgery. Cerebral desaturation and hypersaturation were an episode of Scto2 below and above a given threshold for ≥15 seconds during surgery, respectively. The thresholds based on relative changes by referring to the baseline measurement were <80%, <85%, <90%, <95%, and <100% baseline for desaturation and >105%, >110%, >115%, and >120% baseline for hypersaturation. The thresholds based on absolute values were <50%, <55%, <60%, <65%, and <70% for desaturation and >75%, >80%, >85%, and >90% for hypersaturation. The given area under the threshold (AUT)/area above the threshold (AAT) was analyzed. Delirium was assessed until postoperative day 5. The primary analysis was the association between the minimum Scto2 and delirium using multivariable logistic regression controlled for confounders (age, OLV time, use of midazolam, occurrence of hypotension, and severity of pain). The secondary analysis was the association between cerebral desaturation/hypersaturation and delirium, and between the AUT/AAT and delirium using multivariable logistic regression controlled for the same confounders. Multiple testing was corrected using the Holm-Bonferroni method. We additionally monitored somatic tissue oxygen saturation on the forearm and upper thigh. RESULTS Delirium occurred in 35 (20%) of 175 patients (65 ± 6 years old). The minimum left or right Scto2 was not associated with delirium. Cerebral desaturation defined by <90% baseline for left Scto2 (odds ratio [OR], 5.82; 95% confidence interval [CI], 2.12-19.2; corrected P =.008) and <85% baseline for right Scto2 (OR, 4.27; 95% CI, 1.77-11.0; corrected P =.01) was associated with an increased risk of delirium. Cerebral desaturation defined by other thresholds, cerebral hypersaturation, the AUT/AAT, and somatic desaturation and hypersaturation were all not associated with delirium. CONCLUSIONS Cerebral desaturation defined by <90% baseline for left Scto2 and <85% baseline for right Scto2, but not the minimum Scto2, may be associated with an increased risk of postthoracotomy delirium. The validity of these thresholds needs to be tested by randomized controlled trials.

Abstract
Narrow-band-gap III-V semiconductor nanowires (NWs) with a suitable band structure and strong light-trapping ability are ideal for high-efficiency low-cost solar water-splitting systems. However, due to their nanoscale dimension, they suffer more severe corrosion by the electrolyte solution than the thin-film counterparts. Thus, short-term durability is the major obstacle for using these NWs for practical water-splitting applications. Here, we demonstrated for the first time that a thin layer (∼7 nm thick) of compact TiO2 deposited by atomic layer deposition can provide robust protection to III-V NWs. The protected GaAs NWs maintain 91.4% of its photoluminescence intensity after 14 months of storage in ambient atmosphere, which suggests the TiO2 layer is pinhole-free. Working as a photocathode for water splitting, they exhibited a 45% larger photocurrent density compared with unprotected counterparts and a high Faraday efficiency of 91% and can also maintain a record-long highly stable performance among narrow-band-gap III-V NW photoelectrodes; after 67 h photoelectrochemical stability test reaction in a strong acid electrolyte solution (pH = 1), they show no apparent indication of corrosion, which is in stark contrast to the unprotected NWs that fully failed after 35 h. These findings provide an effective way to enhance both stability and performance of III-V NW-based photoelectrodes, which are highly important for practical applications in solar-energy-based water-splitting systems.

Abstract
AIMS/INTRODUCTION To systematically review the risk factors for new-onset diabetes mellitus after kidney transplantation, and to provide a theoretical basis for the prevention and management of new-onset diabetes mellitus after kidney transplantation. MATERIALS AND METHODS We searched PubMed, Web of Science, Embase, the Cochrane Library databases and other databases for case-control studies related to risk factors for new-onset diabetes mellitus after kidney transplantation published between January 2005 and July 2019. A meta-analysis of data on risk factors for new-onset diabetes mellitus after kidney transplantation from the included studies was carried out. A narrative review of risk factors for new-onset diabetes mellitus after kidney transplantation was also carried out. RESULTS A total of 24 case-control studies were included in the meta-analysis, with a total of 7,140 patients. There were 1,598 patients with new-onset diabetes mellitus after kidney transplantation, and 5,542 patients without new-onset diabetes mellitus after kidney transplantation. The meta-analysis results showed that age, polycystic kidney disease, family history of diabetes, body mass index, acute rejection, tacrolimus use, hepatitis B virus infection, hepatitis C virus infection and hypertension were associated with new-onset diabetes mellitus after kidney transplantation, whereas sex, sirolimus use, cyclosporin A use, steroid use and cytomegalovirus infection were not associated with new-onset diabetes mellitus after kidney transplantation. CONCLUSIONS Older age, body mass index, family history of diabetes, tacrolimus use, history of hypertension, polycystic kidney disease, acute rejection, hepatitis B virus infection and hepatitis C virus infection are risk factors for new-onset diabetes mellitus after kidney transplantation. Therefore, the clinical implications of these factors warrant attention.

Abstract
Photoelectrochemical (PEC) water splitting is a promising clean route to hydrogen fuel. The best-performing materials (III/V semiconductors) require surface passivation, as they are liable to corrosion, and a surface co-catalyst to facilitate water splitting. At present, optimal design combining photoelectrodes with oxygen evolution catalysts remains a significant materials challenge. Here, we demonstrate that nickel-coated amorphous three-dimensional (3D) TiO2 core-shell nanorods on a TiO2 thin film function as an efficient hole-extraction layer and serve as a protection layer for the GaAs photoanode. Transient-absorption spectroscopy (TAS) demonstrated the role of nickel-coated (3D) TiO2 core-shell nanorods in prolonging photogenerated charge lifetimes in GaAs, resulting in a higher catalytic activity. This strategy may open the potential of utilizing this low-cost (3D) nanostructured catalyst for decorating narrow-band-gap semiconductor photoanodes for PEC water splitting devices.

Abstract
Objective: To investigate the correlation between tissue oxygen saturation during one lung ventilation and postoperative neuro cognitive dysfunction (PND) in elderly patients in thoracic surgery. Methods: One hundred and twenty-eight elderly patients who underwent selective lobectomy from August 2017 to September 2018 in the Forth Hospital of Hebei Medical University were enrolled. The patients were divided into PND group (n=34) and non-PND group (n=94) according to whether PND occurred 3 days after surgery. Tissue oxygenation was monitored at bilateral forebrain, brachioradialis muscle and quadriceps. Cognitive function was assessed by the Montreal Cognitive Assessment (MoCA) at baseline and the third day after the operation. Postoperative cognitive dysfunction was diagnosed if postoperative MoCA decreased at least 2 scores compared with preoperative baseline value. Outcomes included the incidence of PND, the incidence of tissue oxygen desaturation during one lung ventilation, postoperative complications within 30 days and length of postoperative in-hospital stay. Logistic regression was used to screen independent risk factors of PND. Results: The incidence of postoperative cognitive dysfunction was 26.6% (34/128). The two groups had no significant difference in the incidence of non-neurogenic complications (new occurred arrhythmia, pulmonary infection, pulmonary embolism, acute renal insufficiency, sepsis, deep vein thrombosis, all P>0.05). However, the length of postoperative in-hospital stay of PND group was 7.0 (6.0, 8.5) d, which was longer than that of non-PND group [6.0 (5.0, 8.0) d]. There was significant difference (U=2.394, P=0.017) . There was no correlation between the two groups within the minimum of SmtO(2) in upper limbs (OR=0.988, 95%CI: 0.954-1.024, P=0.519) and the range of desaturation (OR=1.010, 95%CI: 0.979-1.042, P=0.514) , as well as the minimum of SmtO(2) in legs (OR=0.996, 95%CI: 0.961-1.032, P=0.832) and the range of desaturation (OR=0.997, 95%CI: 0.971-1.025, P=0.851) . Multivariate logistic regression analysis showed that the high ASA grade (OR=2.617, 95%CI: 1.112-6.157, P=0.029) and the minimum of cerebral oxygen saturation during one lung ventilation (OR=0.931, 95%CI: 0.880-0.986, P=0.014) were independent risk factors of PND. There was no statistical correlation between muscle oxygen saturation and PND. Conclusion: Cerebral desaturation during one lung ventilation increased the risk of PND in elderly patients, while the muscle desaturation has no statistical correlation with PND.

Abstract
OBJECTIVE MicroRNAs are a group of gene expression regulators and some of which have been confirmed to be associated with acute viral myocarditis (VM). This study aims to find new biomarkers for VM diagnosis and explore the roles of miRNAs during the pathogenesis of VM. PATIENTS AND METHODS 23 patients with acute myocarditis and 12 controls were included in this research. The expression of 10 candidate miRNAs in the serum exosome was examined by qRT-PCR. The direct targets were predicted using bioinformatics tools and then confirmed by dual luciferase assay and immunoblotting. Levels IL-6 of cell culture supernatants were determined by enzyme-linked immunosorbent assay. Six weeks old male mice were injected intraperitoneally with Coxsackievirus B3 (CVB3) and then treated by miRNA inhibitors through tail vein injection. RESULTS Five miRNAs were found to have disturbed expression in the exosome and may have the potential to be used as biomarker for VM diagnosis. Meanwhile, the expression of miR-30a and -181d was also altered in the cells after CVB3 infection. We identified SOCS3 as a direct target of miR-30a and -181d. Furthermore, during CVB3 infection, up-regulated miR-30a and -181d are related to enhanced IL-6 level via modulating SOCS3 expression. miRNA inhibitors injection increased mice survival rate after CVB3 infection. CONCLUSIONS miR-30a and -181d contribute to the over-activated inflammatory response to viral infection of the heart during coxsackievirus infection.

Abstract
Puerarin, an important isoflavone, has been widely used for the treatment of angina and hypertension. In this work, we developed a novel electrochemical sensor for the detection of puerarin based on the hybrid of reduced graphene oxide (RGO) and molecularly imprinted polymer (MIP). The RGO/MIP sensor functions by target puerarin recognition and electro-oxidization via a two-proton and two-electron process, enabling the detection of puerarin with good selectivity and high sensitivity. The MIP layer was integrated on the surface of RGO by the electro-co-polymerization of o-phenylenediamine (monomer) and puerarin (template), resulting in high surface area, binding capacity, good conductivity and faster mass transfer. The nanostructure of the RGO/MIP hybrid was demonstrated using scanning electron microscopy (SEM) and atomic force microscopy (AFM). Experimental conditions involved in the sensor fabrication process were evaluated. Under the optimized condition, a wide linear range (0.02 μM ∼ 40 μM) and a low detection limit (0.006 μM) were achieved. The sensor was applied to detect puerarin in human urine and injection samples, and the result was comparable with that of the gold standard method of high-performance liquid chromatography (HPLC), indicating a promise in the further application to pharmacokinetics or therapeutic drug monitoring.

Abstract
OBJECTIVE To identify the functioning mode of miR-378 on non-small cell lung cancer (NSCLC) and provide therapeutic targets for NSCLC. PATIENTS AND METHODS Expression levels of miR-378 in human NSCLC tissue samples and NSCLC-derived cell lines were measured by using quantitative Real-time polymerase chain reaction (PCR). Cell proliferation capacity was assessed by methyl thiazolyl tetrazolium (MTT) assay and colony formation assay. Cell apoptosis and cell cycle distribution were identified by flow cytometry. Downstream target gene was confirmed by using luciferase and Western blotting assays. RESULTS MiR-378 was significantly elevated in NSCLC tissues when compared with para-carcinoma tissues (n=42). Decreased-miR-378 could attenuate cell proliferation capacity, as well as promoted cell apoptosis and induced cell cycle arrest at G0/G1 phase. FOXG1 was chosen as the target gene of miR-378 by bioinformatics analysis and luciferase reporter assay. Moreover, restoration of miR-378 could impair the tumor suppression role of downregulated-miR-378 on NSCLC growth. CONCLUSIONS Decreased-miR-378 exerted tumor-suppressive effects on NSCLC growth via targeting FOXG1 in vitro, which provided an innovative and candidate target for diagnosis and treatment of NSCLC.

Abstract
Objective To determine the association between levels of serum 25-hydroxyvitamin D (25[OH]D) and soluble fms-like tyrosine kinase 1 (sFlt-1) in patients with preeclampsia. Methods Clinical and demographic data were collected from patients with preeclampsia and healthy pregnant controls. Serum 25(OH)D and sFlt-1 levels were evaluated by enzyme-linked immunosorbent assay and their correlations were determined using Spearman’s rank correlation coefficient. Associations between serum 25(OH)D and sFlt-1 levels and disease severity and clinical parameters were evaluated. Results Significantly lower serum 25(OH)D and higher sFlt-1 levels were observed in patients with preeclampsia (n = 100) versus controls (n = 100), and 25(OH)D was inversely correlated with sFlt-1 in patients with preeclampsia. Serum 25(OH)D levels were reduced, while sFlt-1 concentration was increased in patients with severe versus mild preeclampsia. Serum 25(OH)D levels were reduced in late-onset versus early-onset severe preeclampsia. Patients with preeclampsia who had lower serum 25(OH)D or elevated sFlt-1 levels showed significantly higher blood pressure indexes versus those with higher 25(OH)D or lower sFlt-1. Conclusions Low serum 25(OH)D and high sFlt-1 may be candidate biomarkers for preeclampsia diagnosis and prognosis.

Abstract
BACKGROUND HIV progression is characterized by immune activation and microbial translocation from the gut. Short-chain fatty acids (SCFAs) are essential for gut homeostasis. Decreased intestinal SCFAs play a role in rapid HIV progression. AIMS To compare the SCFA profile, intestinal microbiome, and intestinal mucosal injury between patients with HIV (but not AIDS) and healthy controls. METHODS This was a prospective study of 15 patients without AIDS and 10 controls conducted between July 2016 and January 2017 at the Institute of Dermatology and Venereology (Sichuan Academy of Medical Sciences). Stool specimens were collected to analyze the microbiome and SCFAs. Blood I-FABP and D-lactate (gut injury markers) were measured as well as T cells in HIV-positive patients. Intestinal mucosa was observed by colonoscopy. RESULTS Rikenellaceae, Microbacteriaceae, Roseburia, Lachnospiraceae, Alistipes, and Ruminococcaceae were decreased, while Moraxellaceae and Psychrobacter were increased in HIV-positive patients. Butyric acid (p = 0.04) and valeric acid (p = 0.03) were reduced in HIV-positive patients. Colonoscopy revealed no visible damage in all subjects. There were no differences in I-FABP and D-lactate between groups. Butyric and valeric acids mainly positively correlated with Rikenellaceae, Ruminococcaceae, Alistipes, Roseburia, and Lachnospiraceae. CD8+ cells were positively correlated with Proteobacteria. CD4+ cells, and CD4/CD8 were negatively correlated with acetic acid. CD8+ cells were positively correlated with valeric acid. CONCLUSION The differences in the distribution of intestinal flora between HIV-infected and healthy individuals, especially some SCFAs, suggest that there is already a predisposition to intestinal mucosa damage in HIV-infected individuals.

Abstract
The study was to investigate the effects of ligustrazine on rats with cerebral ischemia-reperfusion (I/R) injury and to explore the potential mechanism. Transient focal cerebral ischemia Wistar rat model was established through middle cerebral artery occlusion. The cerebral I/R injury rats were treated with intraperitoneal injection of ligustrazine (1, 3, and 10 mg/kg). Human amniotic epithelial cells (HAECs) were treated with ligustrazine (1, 10, 100 μM) and PI3K inhibitor wortmannin (100 μM), following oxygen-glucose deprivation (OGD) treatment. The expression levels of protein kinase B (PKB or AKT), phospho-Akt (p-Akt), endothelial nitric oxide synthase (eNOS), and phosphor-eNOS (p-eNOS) in HAECs and brains of rats were measured by Western blot. The levels of nitric oxide (NO) in HAECs were measured by Griess method using NO2-/NO3- Assay Kit. Infarct volume and neurological deficits were evaluated 24 h after reperfusion. The levels of NO, p-Akt/Akt, and p-eNOS/eNOS in HAECs were significantly reduced after OGD, but ligustrazine treatment increased the levels of those factors in a dose-dependent manner, while those increases were reversed by PI3K inhibitor wortmannin. Similarly, p-Akt/Akt and p-eNOS/eNOS in brain tissue of rats with I/R were significantly reduced compared with control group (p < 0.05), but ligustrazine treatment increased the levels of p-Akt and p-eNOS in a dose-dependent manner (p < 0.05), while those increases were also reversed by using wortmannin. Ligustrazine also improved the damage of rat brain tissue caused by I/R, but wortmannin reversed the improvement. Ligustrazine plays a neuroprotective role in rats with cerebral I/R injury through the activation of PI3K/Akt pathway.

Abstract
In patients undergoing major surgery, complete handover of intraoperative anesthesia care is associated with adverse postoperative outcomes including high mortality and more major complications. The purpose of this study was to explore the association between the intraoperative complete handover between anesthesiologists and the occurrence of postoperative delirium. This was a secondary analysis of the database of a previously published clinical trial. Seven hundred patients aged 65 years or older, who were admitted to the intensive care unit after noncardiac surgery, were included. Delirium was assessed with the Confusion Assessment Method for the Intensive Care Unit twice daily during the first 7 postoperative days. Other postoperative outcomes were also monitored. The association between the intraoperative complete handover of anesthesia care and the development of postoperative delirium was analyzed with a logistic regression model. Of the 700 enrolled patients, 111 (15.9%) developed postoperative delirium within 7 days. After correction for confounding factors, intraoperative complete handover between anesthesiologists was associated with an increased risk of postoperative delirium (OR 1.787, 95% CI 1.012–3.155, P = 0.046). Patients with intraoperative complete handover also had higher incidence of non-delirium complications (P = 0.003) and stayed longer in hospital after surgery (P = 0.002). For elderly patients admitted to the intensive care unit after noncardiac surgery, intraoperative complete handover of anesthesia care was associated with an increased risk of postoperative delirium.

Abstract
The effects of X-ray radiation on spermatogenesis, sperm motility, and PIWI-interacting RNAs (piRNAs) in mice were analyzed. Male C57BL/6 J mice were divided into control and two irradiation groups ( n = 9 mice/group). After irradiation of their reproductive regions, the mice were fed for 3 days (irradiation group 1) or 7 days (control and irradiation group 2). The sperm viability, motility, velocity, and motion curve were analyzed. After piRNA expression profiling, quantitative reverse-transcription polymerase chain reaction was conducted for validation. Ionizing radiation led to vessel dilation and congestion, fewer spermatogenic cells, and reduced sperm production compared to the control. At 3 and 7 days postirradiation, the sperm count (grade d) increased while sperm viability and sperm lateral head displacement decreased. At 7 days, the sperm abnormality rate was higher compared to the control. Many piRNAs were differentially expressed after irradiation, including decreased and increased expression of mmu_piR_009082 and mmu_piR_020217, respectively. Downregulated piRNAs were involved in Rap1 signaling, non-homologous end-joining, hedgehog signaling, oxytocin signaling, and cholinergic synapse. Upregulated piRNAs participated in pathways including proteoglycans in cancer, phosphatidylinositol signaling, cGMP-PKG signaling, and stem cell pluripotency regulation. X-ray irradiation inhibited spermatogenesis and increased abnormal sperm rate in mice. piRNA-related signaling pathways may be involved in this process.

Abstract
Objective: To investigate all coding regions of amyotrophic lateral sclerosis (ALS)-related gene Senataxin (SETX) in sporadic amyotrophic lateral sclerosis patients of Chinese origin. Methods: From January 2010 to December 2014, the peripheral venous blood samples and clinical data were collected from 311 patients with sporadic amyotrophic lateral sclerosis (SALS) and 311 healthy controls who were of Chinese ancestry from the Department of Neurology, Chinese PLA General Hospital.Genomic DNA was extracted from peripheral venous blood of all participants using standard methods. The coding regions of SETX were amplified by polymerase chain reaction (PCR) and screened for mutations using next-generation sequencing technology. The online software SIFT and PolyPhen-2 were used to analyze the conservation of an altered amino acid and predict the potential pathogenicity of identified mutations. The SPSS 22.0 software was used to analyze the clinical feature of all participants. Results: Tenkinds of rare and one novel nonsynonymous mutations were identified and were absent in 311 controls. Twelve (3.86%) patients carried one SETX gene mutation. Five (1.61%) out of above-mentioned 12 patients carried highly pathogenic mutations including p. Pro1868Leu (c.5603G>A), p. Pro1331Leu (c.3992G>A), p. Glu756Val (c.2267T>A), p. Leu564Val (c.1690A>C), and p. Asn144Ser (c.431T>C). Patients carried SETX mutations were not different from other patients in onset age. Conclusion: Mutations in SETX are likely to be a pathogenesis for Chinese sporadic amyotrophic lateral sclerosis.

Abstract
Reducing the diameter of silver nanowires has been proven to be an effective way to improve their optoelectronic performance by lessening light attenuation. The state-of-the-art silver nanowires are typically around 20 nm in diameter. Herein we report a modified polyol synthesis of silver nanowires with average diameters as thin as 13 nm and aspect ratios up to 3000. The success of this synthesis is based on the employment of benzoin-derived radicals in the polyol approach and does not require high-pressure conditions. The strong reducing power of radicals allows the reduction of silver precursors to occur at relatively low temperatures, wherein the lateral growth of silver nanowires is restrained because of efficient surface passivation. The optoelectronic performance of as-prepared 13 nm silver nanowires presents a sheet resistance of 28 Ω sq-1 at a transmittance of 95% with a haze factor of ∼1.2%, comparable to that of commercial indium tin oxide (ITO).

Abstract
Smart photovoltaic windows represent a promising green technology featuring tunable transparency and electrical power generation under external stimuli to control the light transmission and manage the solar energy. Here, we demonstrate a thermochromic solar cell for smart photovoltaic window applications utilizing the structural phase transitions in inorganic halide perovskite caesium lead iodide/bromide. The solar cells undergo thermally-driven, moisture-mediated reversible transitions between a transparent non-perovskite phase (81.7% visible transparency) with low power output and a deeply coloured perovskite phase (35.4% visible transparency) with high power output. The inorganic perovskites exhibit tunable colours and transparencies, a peak device efficiency above 7%, and a phase transition temperature as low as 105 °C. We demonstrate excellent device stability over repeated phase transition cycles without colour fade or performance degradation. The photovoltaic windows showing both photoactivity and thermochromic features represent key stepping-stones for integration with buildings, automobiles, information displays, and potentially many other technologies.

Abstract
Ten patients diagnosed with multifocal motor neuropathy (MMN) were recruited in the Department of Neurology at Chinese PLA General Hospital from January 1, 2009 to August 31, 2015. The clinical and electrophysiological features were analyzed retrospectively. All patients complained of progressive asymmetric limb weakness, which was more severe in distal than in proximal. Five presented muscle atrophy. None had sensory disturbances. All suffered diminished or disappeared tendon reflex, whereas Babinski signs were negative. Multi-focal conduction block (CB) was confirmed by nerve conduction studies (NCS) in all patients and 7 showed spontaneous potentials in needle electrode electromyography. Abnormal sensory nerve conduction was seen in 3 patients. Laboratory test revealed anti-ganglioside GM1 antibody in cerebrospinal fluid (CSF) in 6 cases and elevated CSF protein in 7 cases. Limb weakness alleviated greatly in 9 cases after intravenous immunoglobulin (IVIg) treatment. But the other one reported poor response, who had long course of disease, serious limb weakness and obvious muscle atrophy. Motor nerve damage is the most important manifestation of MMN and sensory nerve damage may also appear. NCS is essential to the diagnosis of this disease, with CB as the characteristic electrophysiological feature. IVIg is an effective treatment.
