Recently, male reproductive health has attracted extensive attention, with the adverse effects of circadian disruption on male fertility gradually gaining recognition. However, the mechanism by which circadian disruption leads to damage to male reproductive system remains unclear. In this review, we first summarized the dual regulatory roles of circadian clock genes on the male reproductive system: (1) circadian regulation of testosterone synthesis via the hypothalamic-pituitary-testicular (HPT) and hypothalamic-pituitary-adrenal (HPA) axes; (2) non-circadian regulation of spermatogenesis. Next, we further listed the possible mechanisms by which circadian disruption impairs male fertility, including interference with the oscillatory function of the reproductive system, i.e., synchronization of the HPT axis, crosstalk between the HPT axis and the HPA axis, as well as direct damage to germ cells by disturbing the non-oscillatory function of the reproductive system. Future research using spatiotemporal omics, epigenomic assays, and neural circuit mapping in studying the male reproductive system may provide new clues to systematically unravel the mechanisms by which circadian disruption affects male reproductive system through circadian clock genes.

OBJECTIVES: To investigate the prevalence rate of non-alcoholic fatty liver disease (NAFLD) in overweight/obese children who visit a hospital, and to explore the influencing factors of NAFLD, in order to provide a basis for the prevention of NAFLD in overweight/obese children. METHODS: Overweight/obese children who visited Hunan Children's Hospital from June 2019 to September 2021 were recruited. The prevalence rate of NAFLD was examined. Logistic regression analysis was used to explore the factors influencing the development of NAFLD [non-alcoholic fatty liver (NAFL) and non-alcoholic steatohepatitis (NASH)]. Receiver operating characteristic curve analysis was used to evaluate the predictive value of the influencing factors for NAFL and NASH. RESULTS: A total of 844 overweight/obese children aged 6-17 years were enrolled. The prevalence rate of NAFLD in overweight/obese children was 38.2% (322/844), among which the prevalence rates of NAFL and NASH were 28.8% (243/844) and 9.4% (79/844), respectively. Multivariate logistic regression analysis showed that the increase of waist-to-hip ratio (WHR) and low high-density lipoprotein cholesterol (HDL-C) were associated with the development of NAFL and NASH (P<0.05). The receiver operating characteristic curve analysis showed that the combined measurement of WHR and HDL-C had a predictive value for NAFL (area under the curve: 0.653, 95%CI: 0.613-0.694), and for NASH (area under the curve: 0.771, 95%CI: 0.723-0.819). CONCLUSIONS The prevalence rate of NAFLD in overweight/obese children who visit a hospital is high. WHR and HDL-C are associated with the development of NAFLD and the combined measurement of WHR and HDL-C has a certain value for predicating the development of NAFLD.

From January 2019 to December 2021, overweight and obese children who visited in health outpatient Center of Hunan Children's Hospital were studied to explore and analyze the rate, related factors and patterns of multimorbidity of overweight and obesity-related diseases in children in Hunan Province. Univariate and multivariate logistic regression models were used to analyze the multimorbidity-related factors of overweight and obesity-related diseases in children. Association rules (apriori algorithm) were used to explore the multimorbidity patterns of overweight and obesity-related diseases in children. A total of 725 overweight and obese children were included in this study. The multimorbidity rate of overweight and obesity-related diseases in children was 46.07% (334/725). Age, waist circumference, the frequency of food consumption such as hamburgers and fries and adding meals before bedtime were multimorbidity-related factors of overweight and obesity-related diseases in children. The multimorbidity associated with nonalcoholic fatty liver disease (NAFLD) was relatively common. The patterns with the top three support degrees were "NAFLD+dyslipidemia","NAFLD+hypertension" and "NAFLD+hyperuricemia". The patterns with the top three confidence and elevation degrees were "Hypertension+dyslipidemia => NAFLD","Hyperuricemia => NAFLD" and "NAFLD+hypertension => dyslipidemia".

Recent research has highlighted structural and functional abnormalities in the cerebral cortex of patients with premature ejaculation (PE). These anomalies could play a pivotal role in the physiological mechanisms underlying PE. This study leveraged functional magnetic resonance imaging (fMRI), a noninvasive technique, to explore these neural mechanisms. We conducted resting-state fMRI scans on 36 PE patients and 22 healthy controls (HC), and collected data on Premature Ejaculation Diagnostic Tool (PEDT) scores and intravaginal ejaculation latency time (IELT). Employing a surface-based regional homogeneity (ReHo) approach, we analyzed local neural synchronous spontaneous activity, diverging from previous studies that utilized a volume-based ReHo method. Areas with significant ReHo differences between PE and HC groups underwent surface-based functional connectivity (FC) analysis. Significant discrepancies in ReHo and FC across the cortical surface were observed in the PE cohort. Notably, PE patients exhibited decreased ReHo in the left triangular inferior frontal gyrus and enhanced ReHo in the right middle frontal gyrus. The latter showed heightened connectivity with the left lingual gyrus and the right orbital superior frontal gyrus. Furthermore, a correlation between ReHo and FC values with PEDT scores and IELT was found in the PE group. Our findings, derived from surface-based fMRI data, underscore specific brain regions linked to the neurobiological underpinnings of PE.

Evidence and value：impact on DEcisionMaking （EVIDEM） framework was developed by EVIDEM collaboration. Its core is the combination of multiple criteria decision analysis （MCDA） model and standardized health technology assessment （HTA） report， which aims to evaluate the overall value of medical interventions. It has been tested and implemented in the real-world evaluation environments. After more than 10 years of development， EVIDEM framework has been updated to version 10， and the relevant operation manuals have been published. More than 40 countries have joined the collaboration and more than 20 countries have carried out relevant studies. The framework is constructed with patients， population and sustainability as the overall goals， combing the evidence and value， forming a relatively complete decision-making framework system composed of 2 levels， 7 dimensions and 20 criteria. The two levels include normative universal criteria and contextual criteria. The normative universal criteria， namely EVIDEM core model， is the quantitative evaluation， consisting of 5 dimensions and 13 criteria. Contextual criteria， namely contextual tools， are qualitative evaluation， consisting of 2 dimensions and 7 criteria. The specific operation steps of EVIDEM framework include selecting and constructing criteria， assigning weights， integrating and evaluating evidence， quantitative and qualitative evaluation of value， comprehensive value estimation and ranking based on value estimation. EVIDEM framework is applicable to disease diagnosis， treatment， management and other fields. Its application scope includes medical insurance reimbursement， clinical practice decision-making， drug selection and so on， which can provide a method for more systematic， transparent and scientific healthcare decision-making. At present， the framework has been introduced into the field of traditional Chinese medicine and can provide a scientific and feasible evaluation tool and methodology system for the clinical comprehensive evaluation of Chinese patent medicine.

Objective: To investigate the prevalence of suicidal ideation among MSM, and to explore the influence of perceived social support and depression on suicidal ideation and the possible pathway. Methods: MSM who are ≥18 years, HIV-negative, and ever had sex with men (oral sex/anal sex) in the last year participated in is study. Cross-sectional survey and convenient sampling method were used to recruit MSM through a male social interaction platform Blued 7.5 software from December 2020 to March 2021, with a questionnaire survey. Demographic questionnaire, Perceived Social Support Questionnaire and Center for Epidemiologic Studies Depression Scale were employed to collect data. Mplus 8.3 was used for data analysis. Results: Among 1 394 eligible MSM participants, 25.7% (358/1 394) had suicidal ideation. Perceived social support could have a direct effect on suicidal ideation (β=-0.11, P=0.009), and an indirect effect on suicidal ideation through depression (β=-0.18, P<0.001). Conclusions: Suicidal ideation was found to be lower in MSM with a higher level of perceived social support and a lower level of depression. Using social media to improve MSM's perceived social support and reduce depressive symptoms might be an effective means to prevent suicidal ideation.

Objective:To study the combined use of neoadjuvant chemotherapy and immunotherapy in patients with borderline resectable pancreatic cancer.Methods:The clinical data of patients with pancreatic cancer who were planned to undergo perioperative treatment before surgical treatment at the Fifth Medical Center of PLA General Hospital from January 2019 to June 2021 were retrospectively studied. Of 22 patients with pancreatic cancer, there were 10 males and 12 females, aged (56.0±10.2) years old. Preoperative treatment with chemotherapy (nab-paclitaxel and S-1, AS) and immunotherapy regimen before surgery were given. The baseline characteristics, treatment efficacy, surgical pathology and prognosis were analyzed.Results:Of 22 patients who were treated with neoadjuvant chemotherapy combined with programmed death-1 (PD-1) monoclonal antibody, 11 patients (50%) had tumors in the head, neck and uncinated process of pancreas. On radiographic assessment, one patient achieved CR (4.5%, 1/22), 9 patients PR (40.9%, 9/22), and 11 patients SD (50.0%, 11/22). All patients subsequently underwent R 0 resection. The postoperative pTNM staging showed 91% (20/22) of patients were in stage IA-IIB, 31.8% (7/22) of patients had pT2, 63.6% (14/22) had N0, and 1 patient had pCR. Thirteen patients (54.2%, 13/22) received postoperative adjuvant therapy. The median recurrence-free survival (RFS) was 6.4 months and the median time to progression (TTP) was 12.8 months. The median overall survival of patients was not reached. Postoperative pathology TNM staging IIA to III ( HR=3.63, 95% CI: 1.18-11.20, P=0.025) and postoperative pathology T2-3 stage ( HR=2.02, 95% CI: 1.01-5.05, P=0.049) were significantly associated with RFS. Postoperative pathology TNM stages IIA to III ( HR=2.39, 95% CI: 1.04-5.50, P=0.041) and postoperative pathology T2-3 stage ( HR=2.53, 95% CI: 1.26-5.09, P=0.009) were significantly associated with TTP. Conclusion:AS combined with PD-1 monoclonal antibody showed good efficacy as a neoadjuvant therapy for patients with borderline-resectable pancreatic cancer.

OBJECTIVE: To observe the effect of electroacupuncture (EA) pretreatment on inflammatory reaction, apoptosis and expression of Yes-associated protein (YAP) of ischemic penumbra of cerebral cortex in cerebral ischemia reperfusion injury rats, and to explore the possible mechanism of its neuroprotection effect. METHODS: A total of 84 SD rats were randomized into a sham operation group (12 rats), a model group (18 rats), an EA group (18 rats), an EA+YAP virus transfection group (18 rats) and an EA+virus control group (18 rats). Except for the sham operation group, thread embolization method was adopted to establish the middle cerebral artery occlusion (MCAO) model in rats of the other groups. EA was applied at "Baihui" (GV 20) and "Dazhui" (GV 14) for 30 min in the 3 EA intervention groups 2 h before model establishment, disperse-dense wave, 2 Hz/15 Hz in frequency and 1 mA in intensity. Adenovirus transfection technique was used to induce gene silencing of YAP in the EA+YAP virus transfection group, and adenovirus vectors was injected as negative control in the EA+virus control group 4 d before model establishment. Twenty-four hours after model establishment, neurological function score was evaluated, the relative cerebral infarction area was observed by TTC staining, the apoptosis in the ischemic penumbra of cerebral cortex was detected by TUNEL staining, the levels of inflammatory factors IL-1β, IL-6 and TNF-α in the ischemic penumbra of cerebral cortex was detected by ELISA method, the expression of YAP was detected by Western blot and immunofluorescence. RESULTS: Compared with the sham operation group, the expression of YAP was increased in the model group ( CONCLUSION Electroacupuncture pretreatment can effectively improve the ischemia reperfusion injury, its mechanism may be related to up-regulating the expression of YAP in the ischemic penumbra of cerebral cortex and relieving the apoptosis and inflammatory reaction.

Objective:To study the change of soil environment and yield of Angelica sinensis when cultivated on the film side and and open field sides，and to explore the influence of garlic volatiles and film-side cultivation on continuous cropping A. sinensis，so as to provide some certain theoretical basis for the saying that the A. sinensis garlic intercropping mode and film-side cultivation could alleviate continuous cropping A. sinensis. Method:In this study， the effects of garlic on soil environment and yield of A. sinensis cultivated on film side and crop rotation were discussed through the determination and analysis of soil microorganism quantity，soil enzyme activity and yield of Angelica sinensis in the rhizosphere of A. sinensis. Result:The number of bacteria and actinomycetes in the rhizosphere soil of A. sinensis increased significantly， while the number of fungi decreased significantly. Among them， the number of bacteria and actinomycetes in the intercropping of A. sinensis and garlic on the film side increased by 104% and 146.89% on average as compared with that of the control （monoculture under continuous cropping open field），and the number of fungi decreased by 39.28% on average as compared with that of control group. When the enzyme activity in the rhizosphere soil was significantly increased under the condition of intercropping with garlic on the film side，the soil urease，sucrase，alkaline phosphatase and acid phosphatase activities under the intercropping of A. sinensis and gralic on the rotation film side were increased by 61.60%，51.09%，203.48% and 76.19% respectively as compared with those in control group. The yield of A. sinensis significantly increased under the condition of intercropping with garlic on the film-side，and the yield of Angelica sinensis under the rotation film-side intercropping with garlic increased by 39.37% as compared with that of control group. Conclusion:Under the mode of film-side cultivation，the interplanting of A. sinensis with garlic can change the number of soil microorganism，improve the activity of soil enzyme，improve the physical and chemical properties of soil， alleviate the obstacle of continuous cropping and guarantee the healthy growth of A. sinensis more effectively.

Objectives: To investigate the prevalence and associated risk factors of tinnitus in Sichuan and Chongqing. Methods: We designed a tinnitus epidemiological questionnaire. The multi-stage stratified cluster random sampling methods was applied to obtain study subjects in six areas (Nanchong, Jiangjin, Fengdu, Yunyang, Suining and Ya'an), which were selected for epidemiological investigation. Home visit completion of epidemiological questionnaires was conducted. The trained investigators guided the respondents to fill in the tinnitus epidemiological questionnaires, and the epidemiological status of six areas on prevalence and risk factor was investigated. SPSS 22.0 software was used for statistical analysis. Results: Sampling population were 10 289, in which 9 273 were valid questionnaires. There were 4 281 males and 4 992 females, with an average age of 47.3 years, among which 34.83% (3 230/9 273) had tinnitus. 3.99% (370/9 273) were diagnosed with bothersome tinnitus. In a multivariable logistic regression mod, the following factors were associated with onsetting of tinnitus: sleep disorder [Odds Ratio(OR)=3.74] and noise exposure(OR=1.99). The risk of disease was lowest in the age of 30-40 years old, while the risk of disease was higher for people under 30 and over 40. In another multivariable logistic regression mode, the following factors were associated with having bothersome tinnitus: older people were more likely to suffer from tinnitus, sleep disorders (OR=4.68) and noise exposure (OR=1.56). Conclusions: The prevalence of tinnitus in Sichuan and Chongqing is about 34.83%, but most of the tinnitus is short-lived and has low loudness, which will not affect the patients. Only a small number of patients with tinnitus (3.99%) persist and affect their health and need treatment. The occurrence and exacerbation of tinnitus may be related to sleep, age, and noise exposure.
