Objective:To compare the efficacies of arthroscopic modified Brostr?m procedure combined with or without peroneal tendon debridement in the treatment of chronic lateral ankle instability (CLAI) concomitant with fibular tendinitis.Methods:A retrospective cohort analysis was conducted on the clinical data of 31 patients with CLAI concomitant with fibular tendinitis, who were treated in Beijing Tongren Hospital, Capital Medical University between March 2019 and December 2021. The patients included 17 males and 14 females, aged 16-57 years [(32.8±9.6)years]. The anterior drawer test and talar tilt test were positive in all patients preoperatively. Diagnosis was confirmed by physical examination and MRI, and calcaneofibular ligament rupture was excluded. Eleven patients received arthroscopic modified Brostr?m procedure combined with peroneal tendon debridement (modified Brostr?m procedure+tendon debridement group), and 20 underwent pure arthroscopic modified Brostr?m procedure (modified Brostr?m procedure group). The operation time, intraoperative blood loss and length of hospital stay were documented. The visual analogue score (VAS) in peroneal tendon area was assessed before operation and at postoperative 2, 6 and 12 weeks. The American Orthopedic Foot and Ankle Society (AOFAS) ankle-hindfoot score and foot and ankle outcome score (FAOS) were assessed before operation and at postoperative 6 and 12 weeks. The anterior drawer test was performed at the last follow-up. The foot and ankle ability measure (FAAM) score was assessed before operation and at the last follow-up. Postoperative wound healing and complications were also observed.Results:All the patients were followed up for 4-19 months [(11.3±3.5)months]. The operation time was (66.0±4.2)minutes in the modified Brostr?m procedure+tendon debridement group, which was significantly longer than (61.5±3.4)minutes in the modified Brostr?m procedure group ( P<0.05). There was no significant difference in intraoperative blood loss or length of hospital stay between the two groups (all P>0.05). Compared with the preoperation, the value of VAS was significantly lowered, and the values of AOFAS ankle-hindfoot score, FAOS and FAAM score were significantly increased at different postoperative timepoints (all P<0.01). No significant differences in the values of VAS, AOFAS ankle-hindfoot score, FAOS or FAAM score were seen between the two groups before operation (all P>0.05). The value of VAS was 3.0(3.0, 4.0) points in the modified Brostr?m procedure+tendon debridement group, being markedly different from 4.0(4.0, 4.0)points in the modified Brostr?m procedure group at 2 weeks postoperatively ( P<0.05). The value of VAS was 2.0(1.0, 3.0)points in the modified Brostr?m procedure+tendon debridement group, being markedly different from 3.0(2.3, 3.0)points in the modified Brostr?m procedure group at 6 weeks postoperatively ( P<0.05). At 12 weeks postoperatively, there was no significant difference in the value of VAS between the two groups ( P>0.05). There were no significant differences in the values of AOFAS ankle-hindfoot score and FAOS between the two groups at 6 or 12 weeks postoperatively (all P>0.05). The anterior drawer test was negative in all patients at the last follow-up. No significant difference was seen in the value of FAAM score between the two groups at the last follow-up ( P>0.05). All incisions were healed well in the first stage after operation, without the occurrence of joint infection, impaired joint motion, nerve injury or deep vein thrombosis. Conclusions:Arthroscopic modified Brostr?m procedure combined with or without peroneal tendon debridement can both improve the foot function in CLAI patients concomitant with fibular tendinitis. However, the combined treatment allows for early pain relief, without increasing the risk of complications, and can therefore contribute to a faster postoperative recovery.

Objective To investigate the effect of cervical manual stratified anastomosis and anastomosis with tube stapler on the recent complications in thoracic laparoscopy combined with radical resection of esophageal cancer.Methods From February 2019 to April 2022,a total of 196 patients who underwent endoscopic surgery for esophageal cancer who met the study criteria were divided into the manual group(87 cases)and the tubulostomy group(109 cases)according to the different ways of gastro-esophageal cervical anastomosis.The incidence of cervical surgery time,total operation time,postoperative anastomotic fistula,anastomotic stenosis and other complications of the two groups were evaluated,and the differences in treatment effects between the two groups were compared.Results The preoperative basic conditions of patients in the manual group and the tube kiss group were comparable,and the cervical anastomosis time in the tube kiss group[(23±3.57)min]was shorter than that in the manual group[(31±4.5)min](P＜0.05),but there was no statistical significance in the overall operation time between the two groups(P＞0.05).The comparison of postoperative anastomotic fistula and anastomotic stenosis between the two groups showed that the manual group was significantly lower than the tube kiss group,and the difference was statistically significant(P＜0.05).Conclusion In thoracic laparoscopic combined with esophageal cancer surgery,cervical manual stratified anastomosis can reduce the incidence of postoperative anastomotic complications.

Pharmacoepidemiology refers to the use of epidemiological research methods in studying the application and use of drugs in large populations to evaluate the safety and efficacy of medical products. Therefore, standardized pharmacoepidemiology research is the basis of the above work. Based on systematic reviews of national and international pharmacoepidemiological methodological standards and guidelines, and in combination with Chinese medical and health practice and experts’ opinions, the Professional Committee of Pharmacoepidemiology of Chinese Pharmaceutical Association developed the group standard, guide on methodological standards in pharmacoepidemiology (T/CPHARMA 002-2019), to better guide the work of pharmacoepidemiology. The guideline was designed to provide advice and reference for pharmacoepidemiology research by government, regulatory agencies, research institutions, and pharmaceutical manufacturers in China.

Objective To investigate the clinical effect of low-temperature plasma radiofrequency with endoscopic laryngoscope in the treatment of adult patients with laryngeal papilloma.Methods From January 2014 to April 2018,60 adult patients with laryngeal papilloma in Zhuji Central Hospital were enrolled in this study.According to the treatment methods,they were divided into control group and observation group,with 30 cases in each group.The control group was treated with laryngoscope tweezers,and the observation group was treated by low temperature plasma radiofrequency with endoscopic laryngoscope.The operation time,intraoperative blood loss,hospitalization time and postoperative complications were recorded.The follow-up was performed on the first day after operation.The recurrence rate and average recurrence time were recorded.Results The average operation time in the observation group was (29.54 ± 4.52)min,which was significantly shorter than (38.85 ± 5.47)min in the control group (t =7.186,P =0.000).The intraoperative blood loss of the observation group was (1.24 ± 0.76) mL,which was significantly lower than (35.69 ± 5.88) mL of the control group (t =31.825,P =0.000).The length of hospital stay of the observation group was (3.83 ± 1.17) d,which was significantly shorter than (4.79 ± 1.47) d of the control group (t =2.798,P =0.006).The incidence rate of postoperative complication in the observation group was 3.33％ (1/30),which was significantly lower than 23.33％ in the control group (x2 =5.192,P =0.022).The mean duration of postoperative recurrence in observation group was (2.42 ± 0.57) months,which was significantly longer than (1.28 ± 0.36) months in the control group(t =9.261,P =0.000).The postoperative recurrenc.e rate of the observation group was 6.67 ％ (2/30),which was significantly lower than that of the control group [40.00 ％ (12/30),x2 =9.316,P =0.002].Conclusion Low temperature plasma radiofrequency with endoscopic laryngoscope in the treatment of adult patients with laryngeal papilloma has less trauma,and can extend the recurrence time,reduce the postoperative recurrence rate.

Objective: To investigate the mental health status of female migrant workers in a city. Methods: From August to December, 2016, cluster random sampling was used to select female migrant workers aged 16-60 years from 10 districts of this city, and Symptom Checklist-90 (SCL-90) and a questionnaire on general status were used. Results: Among these female migrant workers, the detection rates of obsessive-compulsion, hostility, and depression were 6.62%, 4.18%, and 4.10%, respectively. There was a significant difference in the detection rate of mental health issues between the female migrant workers from different districts, with different occupations, or with different education levels (P<0.05) . Districts, occupation, and education level were associated with mental health issues, after adjustment for age (P<0.05) . Conclusion Although female migrant workers in this city have a high mental health level, the issues such as obsessive-compulsion, hostility, and depression should be taken seriously. Targeted mental health surveys and comprehensive interventions should be implemented to improve the mental health level of female migrant workers.

Objective: To study status of social support and its influencing factors in female migrant workers. Methods: Study participants were selected with a random cluster design from participants 16-60 years old in non-registered residents from 10 districts in one city. Social support revalued scale and general questionnaire were used to survey social support status of female migrant workers in August-December of 2016. Results: There was statistic difference in social support among different districts, occupations, and income of female migrant workers (P<0.05) . Results of multiple linear regression demonstrates that districts, occupations, and income of female migrant workers were associated with social support scale (district standarized β=0.03, occupations standarized β=-0.03, incorue standarized β=0.10, P<0.05) . Conclusion We should be attentive to self-employed and Low-income participants among female migrant workers.

Objective:To explore the expression and biological functions of miR-346 in nasopharyngeal carcinoma.Methods:63 cases nasopharyngeal carcinoma tissue and 34 cases nasopharyngeal non-cancer tissues were collected,the miR-346 expression were detected by Real-time PCR between nasopharyngeal carcinoma tissue and nasopharyngeal non-cancer tissues,6 strains of human nasopharyngeal carcinoma cell lines and 1 strain of normal nasopharyngeal epithelial cell immortalized NP69.Two cell lines with middle expression levels in human nasopharyngeal carcinoma cells lines were selected,and transfected into miR-346 inhibitor,the control group (NC group) were with negative control plasmid transfection,miR-346 expression in two groups were detected by Real-time PCR,the proliferation,apoptosis were detected by Brdu-ELISA and flow cytometry,the migration and invasion were detected by Transwell Chambers experiments.Results:Compared with the nasopharyngeal non-cancer tissues,the miR-346 expression in nasopharyngeal carcinoma tissues was significantly increased (P =0.000);compared with the normal nasopharyngeal epithelial cells NP69.the miR-346 expression in human nasopharyngeal carcinoma cell lines was significantly increased (P＜0.05).The CNE-1 and CNE-2 were chose,after the miR-346 inhibitor transfection,the miR-346 expression were significantly lower compared with NC group,the difference was statistically significant (P＜0.05).The proliferation of two kinds of nasopharyngeal carcinoma cell CNE-1 and CNE-2 were restrained after transfection,the difference showed statistically significant 3 days after transfection (P ＜ 0.05).The apoptosis increased significantly,and the migration cell numbers and invasion cell numbers decreased significantly compared with NC group,the differences were statistically significant (P＜0.05).Conclusion:miR-346 is overexpression in nasopharyngeal carcinoma,down-regu-lation of miR-346 inhibits the proliferation,migration,invasion,promotes the apoptosis,miR-346 may act as a oncogene and play an important role in the pathogenesis of nasopharyngeal carcinoma.
