Factors affecting male fertility include lifestyle,psychology,environment.and so on.Pathogenic microorganisms in the genitourinary system can also lead to decline of male fertility.However,doctors tend to ignore the effects of immune responses and oxidative stress caused by pathogenic microorganisms on fertility,thus delaying the optimal time of treatment.This paper reviews the relationship between bacteria(such as Escherichia coli,Helicobacter pylori),viruses((severe acute respiratory syndrome coronavirus 2,human papilloma virus),and other pathogenic microorganisms(mycoplasma and chlamydia)and male infertility,and summarizes the latest research progress,aiming to provide guidance for the multidimensional treatment and to provide new ideas for the prevention of male infertility.

Objective: To investigate the current situation of cyberbullying and health risk behaviors among secondary vocational school students, to explore the effects of cyberbullying on health risk behaviors, so as to provide a reference for formulating intervention strategies to promote adolescent health related behaviors. Methods: From March to April 2023, a field survey was conducted on 1 184 students from one secondary vocational school each in Jilin City and Yanji City by random cluster sampling method. The data was analyzed using Chi square tests and generalized linear models. Results: Among secondary vocational school students, 839 individuals (70.9%) experienced the cyberbullying, and 1 036 individuals (87.5%) had one and more health risk behavior group. There was a positive correlation between cyberbullying and health risk behaviors ( r=0.60, P <0.01). The generalized linear model analysis showed that female and no Internet addiction were negatively correlated with the health risk behaviors of secondary vocational students ( β =-2.75, -8.90), and the single parent families and peer pressure was positively correlated with the health behaviors of secondary vocational students ( β =2.56, 4.82)( P ＜0.05). Secondary vocational students experienced cyberbullying who from single parent families, peer pressure and social oriented internet usage were more likely to engage in health risk behaviors ( β= 3.41, 4.88, 2.20, P <0.05). Conclusions The incidence of cyberbullying and health risk behaviors among secondary vocational school students is relatively high, and cyberbullying can influence the occurrence of health risk behaviors. It is important to focus on and implement guidance for internet use and health behavior education for secondary vocational students from multiple perspectives, including the family, school, and society. Corresponding intervention strategies should be taken to promote the healthy development of adolescents.

Immune escape is one of the ten hallmarks of tumors， which plays an important role in the occurrence and development of tumors. Immune escape refers to a process where tumor cells remodel and edit the immune system through the model of immune clearance， immune balance， and immune escape to "transform" the immune cells into immunosuppressive cells in the tumor microenvironment， so as to support immune escape. The five-stage evolution is the summary of tumor pathogenesis by professor LI Jie. He believes that the gradual development of tumors follows the core pathogenesis of "deficiency-cold-toxin-obstruction-collapse"， in which "depression" runs through the whole process， and cancer toxin is the key. Based on immune editing， this paper combined phenotypic characteristics of tumor cells with the core pathogenesis of the five-stage evolution of professor LI to reveal the biological basis of malignant tumor five-stage evolution. The results indicate that the prominent change from deficiency to cold is the reduction of immune surveillance and the prominent change from toxin to obstruction is immune escape. The final stage of collapse is the outcome of immune failure. Depression is the booster of tumor immune editing. Therefore， the method of reinforcing the healthy Qi and removing toxins was proposed to regulate the immune editing and cut off the five-stage evolution of tumors. Supplementing Qi and warming Yang can reinforce the healthy Qi and restore immune surveillance. Removing toxins and dredging can reverse toxins and immune escape. The harmonizing method can maintain the dynamic balance of immune cells/immunosuppressive cells. Resolving depression can truncate tumor immune editing. Those methods can provide a certain reference for the treatment based on microscopic syndrome differentiation in traditional Chinese medicine （TCM）. In future studies， it is necessary to further explore the specific mechanism of the regulation of immune editing with the methods of supplementing Qi and warming Yang， removing toxins and dredging， their combination， and resolving depression， so as to find out specific Chinese medicines and targets and provide more sufficient evidence for the regulation of tumor immune editing by TCM.

Unicompartmental knee arthroplasty (UKA) is an effective treatment for end-stage anteromedial osteoarthritis of the knee. Medial tibial plateau fracture or femoral condyle fracture may occur after UKA, and its treatment is very challenging. The causes leading to this complication include: surgical technique errors, such as the weakening of posterior cortical strength of the tibial platform during operation, the reduction of bone mass due to too much tibial osteotomy, and the stress concentration in the bone bed due to bad alignment of the prosthesis, etc. Prosthesis design factors, such as press-fit fixation design of cementless UKA prosthesis, and multiple nail holes fixation for tibial osteotomy guide, etc. And the morphology of tibial plateau, such as tibial platform in Asian people with narrow and small shap and medial overhanging condyles. Correct selection of patients, strict surgical principles and standardized surgical techniques are the keys to prevent periprosthetic fractures during and after medial UKA. After the diagnosis is confirmed, the treatment choice mainly depends on the fracture pattern and the stability of the prosthesis.

OBJECTIVE: To observe the clinical effect of single acupoint [Yaotu (extra)] electroacupuncture (EA) therapy on lumbar intervertebral disc herniation (LIDH) and its promotion and application in community medical institutions. METHODS: This research adopted a three-level promotion model, and used multi-center collaboration topics as a platform. A total of 240 patients with LIDH were divided into a group A (top three hospital, 80 cases, 3 cases dropped off), a group B (secondary hospital, 80 cases, 8 cases dropped off), and a group C (community health center, 80 cases, 7 cases dropped off). All groups were treated with EA at a single acupoint [Yaotu (extra)] under the guidance of a unified experimental protocol. The EA was given 60 min each time and performed 3 times a week for a total of 2 weeks. The changes of visual analogue scale (VAS) scores of three groups before and after each treatment were compared, and the clinical efficacy was evaluated. RESULTS: Compared with before each treatment, the VAS scores of three groups after each treatment decreased ( CONCLUSION The single acupoint EA therapy has a significant effect in the treatment of LIDH, can quickly relieve the pain symptoms, and has the characteristics of simple operation and easy control, suitable for promotion and application in primary hospitals.

To scientifically evaluate the intervention effect of Chinese medicine preventive administration(combined use of Huo-xiang Zhengqi Oral Liquid and Jinhao Jiere Granules) on community population in the case of coronavirus disease 2019(COVID-19), a large cohort, prospective, randomized, and parallel-controlled clinical study was conducted. Total 22 065 subjects were included and randomly divided into 2 groups. The non-intervention group was given health guidance only, while the traditional Chinese medicine(TCM) intervention group was given two coordinated TCM in addition to health guidance. The medical instructions were as follows. Huoxiang Zhengqi Oral Liquid: oral before meals, 10 mL/time, 2 times/day, a course of 5 days. Jinhao Jiere Granules: dissolve in boiling water and take after meals, 8 g/time, 2 times/day, a course of 5 days, followed up for 14 days, respectively. The study found that with the intake of medication, the incidence rate of TCM intervention group was basically maintained at a low and continuous stable level(0.01%-0.02%), while the non-intervention group showed an overall trend of continuous growth(0.02%-0.18%) from 3 to 14 days. No suspected or confirmed COVID-19 case occurred in either group. There were 2 cases of colds in the TCM intervention group and 26 cases in the non-intervention group. The incidence of colds in the TCM intervention group was significantly lower(P<0.05) than that in the non-intervention group. In the population of 16-60 years old, the incidence rate of non-intervention and intervention groups were 0.01% and 0.25%, respectively. The difference of colds incidence between the two groups was statistically significant(P<0.05). In the population older than 60 years old, they were 0.04% and 0.21%, respectively. The incidence of colds in the non-intervention group was higher than that in the intervention group, but not reaching statistical difference. The protection rate of TCM for the whole population was 91.8%, especially for the population of age 16-60(95.0%). It was suggested that TCM intervention(combined use of Huoxiang Zhengqi Oral Liquid and Jinhao Jiere Granules) could effectively protect community residents against respiratory diseases, such as colds, which was worthy of promotion in the community. In addition, in terms of safety, the incidence of adverse events and adverse reactions in the TCM intervention group was relatively low, which was basically consistent with the drug instructions.

Objective: To investigate the effect of long-term deep slow-wave sleep deprivation on the gonad axis, sperm abnormality rate, and structure of the testis in male rats and possible mechanisms. Methods: A total of 30 specific pathogen-free male Wistar rats aged 5 weeks were randomly divided into slow-wave sleep deprivation group 1 (SD1 group) , slow-wave sleep and sleep time deprivation group 2 (SD2 group) , and control group, with 10 rats in each group. The flower pot method was used to establish a model of sleep deprivation. In addition to 12-hour sleep deprivation at night, the rats in the SD1 group were given interference once every 24 minutes, and those in the SD2 group were deprived of sleep for 8 minutes every 24 minutes; the rats in the control group were given 12-hour light illumination and then placed in dark environment for 12 hours. All rats were sacrificed by exsanguination from the femoral artery, and the testis, the epididymis, and blood were collected for analysis. Sperm abnormality rate and sperm motility rate were measured, and cauda epididymal sperm counting was performed. ELISA was used to measure the serum levels of testosterone (T) , follicle-stimulating hormone (FSH) , and luteinizing hormone (LH) . Results: Compared with the control group, the SD2 group had a significant increase in organ coefficient of the epididymis (P<0.05) and a significant reduction in sperm motility rate (P<0.05) . There were significant differences between the SD1 group and the SD2 group in the increase in sperm abnormality rate (P<0.05) and the reduction in cauda epididymal sperm count (P<0.05) . The levels of FSH and T tended to increase, and the level of LH tended to decrease. Pathological examination showed degeneration and vacuolization of a small amount of spermatogenic cells in the SD1 group; in the SD2 group, there were significant degeneration, edema, and vacuolization of most spermatogenic cells, some spermatogenic cells were observed in the lumen, and there were no sperms in the lumen. Conclusion Long-term deep slow-wave sleep deprivation impairs the structure of the testis, affects sperm motility rate and sex hormones, and increases the risk of sperm abnormality.

Objective To explore the correlation between arterial iodine fraction ( AIF) obtained with energy spectrum CT and Child-Pugh staging of liver cirrhosis.Methods Retrospectively analyzed the Child-Turcotte-Pugh of hospitalized 80 patients diagnosed as liver cirrhosis (15 cases of Child -A,40 cases of Child -B,and 25 cases of Child-C) and CT examination results.HD750 spectral three-stage CT scanning was conducted in all patients.AIF was calculated with energy spectrum analysis software,and the correlation between AIF and Child-Pugh staging of liver cirrhosis was explored.Results There was no statistically significant difference in the iodine content of hepatic artery and portal vein among different groups(t=1.786,P>0.05).The hepatic artery iodine score pair-wise analysis among different groups showed that the differences were statistically significant(F=30.45,P<0.05). The hepatic artery iodine score was highest in Child-Pugh C group,secondary in Child-Pugh B group and lowest in Child-Pugh A group.AIF and Child-Pugh staging of liver cirrhosis was significantly correlated.Conclusion AIF of liver cirrhosis reveals the state of liver function and is correlated with Child-Pugh staging,thus can be adopted as a supplement in clinical Child-Pugh staging.
