Objective To analyze the correlation between gasdermin E(GSDME)and the occurrence and development of cervical cancer.Methods HPA database and GEPIA2 online website were used to analyze the differential expression of GSDME gene and protein between cervical cancer tissues and normal cervical tissues.GEPIA2 and KM plotter online website was used to analyze the correlation be-tween GSDME gene expression and the pathological staging,survival and prognosis of cervical cancer.cBioPortal online website was used to analyze the GSDME gene mutation in cervical cancer tissues.TIMER2 online website and R-package were used to analyze the correla-tion between GSDME and immune infiltration in cervical cancer tissues.Gene set enrichment analysis was used to analyze the biological function of GSDME in development of cervical cancer.Real-time quantitative polymerase chain reaction(RT-qPCR)and Western blot were used to verify the transcription and translation of GSDME in cervical cancer cell lines.Results Compared with normal cervical tis-sues,the expression of GSDME mRNA and protein in cervical cancer tissues was lower(P＜0.05).Survival analysis showed that the high expression of GSDME gene may be associated with poor prognosis of cervical cancer patients.0.36％of GSDME amplification muta-tion was found in cervical squamous cell carcinoma.There was significant negative correlation between high expression of GSDME gene and B lymphocyte infiltration,whereas a significant positive correlation between high GSDME gene and mast cell infiltration in cervical cancer tissues(P＜0.05).The high expression of GSDME in cervical cancer exhibited a significant negative correlation with glutathione peroxidase activity,mRNA modification,keratin filament,and other biological functions(P＜0.001).RT-qPCR and Western blot con-firmed that the transcription and protein expression of GSDME could be detected in both human papilloma virus(HPV)positive and nega-tive cervical cancer cells.Conclusion GSDME may be a risk factor related to cervical cancer,and the correlation analysis between GS-DME and cervical cancer provides a new perspective for the follow-up targeted treatment of cervical cancer based on GSDME.

Objective To investigate the effect of tripterygium glycosides on the resistance to immune rejection after allogeneic islet transplantation in mice.Methods Twenty C57BL/6 mice were treated with STZ diabetes mellitus and transplanted the islets from Balb/c mice donor,then recipient mice were randomly divided into two groups:triptolide group and model control group(n=10),and were intraperitoneal injected with tripterygium glycoside solutin and equivalent solvent of 5 mg·kg-1·d-1 for 14 days.Blood glucose and body weight were measured within 4 weeks after transplantation.Two weeks later,two groups of grafted islets were stained by HE staining and immunohistochemical staining,the expression of IL-2 protein were detected by Western blotting.Results The level of blood glucose were decreased to normal in the triptolide group and model control group after islet transplantation,but blood glucose gradually increased in the model control group after two weeks.Compared with the model control group,the inflammatory cells were less infiltrated and the immunohistochemical staining of insulin was deeper in the triptolide group.The expression of IL-2 in the triptolide group was significantly decreased(P<0.05).Conclusion Tripterygium glucoside could significantly decrease the inflammatory cell infiltration and inflammation factor expression in the allogeneic islet recipients to reduce the immune rejection and improve graft survival.

Objective: To investigate the status of passive smoking among pregnant women in Jinshan District, Shanghai Municipality, so as to provide insights into developing targeted smoking control measures and promoting maternal and infant health. Methods: Pregnant women who had early pregnancy registration at Jinshan District Community Health Service Center from April 2021 to December 2023 were selected as subjects. The basic information, passive smoking and awareness of passive smoking hazards among pregnant women were collected through questionnaire surveys, and passive smoking rate and awareness rate of passive smoking hazards were analyzed. Results: Totally 8 273 questionnaires were allocated, and 8 216 valid questionnaires were recovered, with an effective rate of 99.31%. The mean age of participants was (29.52±4.60) years. There were 4 991 participants with an education of college degree or above, accounting for 60.75%; 3 565 participants with the first pregnancy, accounting for 43.39%; 3 990 primiparas, accounting for 48.56%; 3 193 participants living with smokers, accounting for 38.86%. A total of 3 710 participants passively smoked, with a passive smoking rate of 45.16%. There were 2 817 participants passively smoked in public places, accounting for 75.93%; 2 253 participants passively smoked in workplaces, accounting for 60.73%; 1 563 participants that passively smoked at home, accounting for 42.13%. The awareness rates regarding the hazards of passive smoking to health, causing lung cancer in adults, causing lung diseases in children, causing preterm birth and low birth weight infants, and causing heart diseases in adults were 92.13%, 88.85%, 87.99%, 82.05% and 62.56%, respectively. Conclusion The rate of passive smoking among pregnant women in Jinshan District is comparatively high, while their awareness regarding non-respiratory diseases emanating from passive smoking is comparatively low.

Objective:The iodine excretion of adult individuals was calculated by two creatinine correction methods of urinary iodine, and the significance and value of the methods to measure individual iodine nutrition levels were assessed to provide a reference basis for further epidemiological investigation and study of iodine deficiency disorders.Methods:Healthy adults aged 18 - 59 years from Fujian Province were recruited and their 24 h urine, fasting urine, and morning spot urine (8:00 - 12:30) were collected and the corresponding urinary iodine and creatinine concentrations were measured. The estimated 24 h urinary iodine excretion was calculated using two different creatinine correction and creatinine estimation formulas were compared with the measured 24 h urinary iodine excretion.Results:There were no significant differences in measured 24 h urinary iodine excretion value, estimated 24 h urinary iodine excretion value 1 of fasting urine and morning spot urine, and estimated 24 h urinary iodine excretion 2 of fasting urine and morning spot urine between genders (μg/d: 195.5 vs 190.9, 190.0 vs 181.7, 160.2 vs 144.2, 174.8 vs 179.2, 148.3 vs 131.5); there were no significant differences in measured 24 h urinary iodine excretion and fasting urinary estimated 24 h urinary iodine excretion 1, estimated 24 h urinary iodine excretion 2 ( P > 0.05), and there were significant differences in measured 24 h urinary iodine excretion and morning spot urinary estimated 24 h urinary iodine excretion 1, estimated 24 h urinary iodine excretion 2 ( P < 0.01). And there were significant linear correlations between measured 24 h urinary iodine excretion and estimated 24 h urinary iodine excretion 1 of fasting urine and morning spot urine, estimated 24 h urinary iodine excretion 2 of fasting urine and morning spot urine ( r = 0.772, 0.266, 0.828, 0.391, P < 0.01). Conclusions:It is feasible to estimate 24 h urinary iodine excretion in adults with creatinine-corrected fasting urinary iodine concentration. Creatinine-corrected fasting urinary iodine concentration can be used as an individual iodine nutrition level evaluation index, but whether it is applicable to children and pregnant women remains to be further studied.

Objective To evaluate the right heart function with echocardiography after right ventricle-pulmonary artery (RV-PA) anastomasis for right ventricle outflow (RVOT) reconstruction in patients with different types of pulmonary atresia and ventricle septal defect(PA/VSD).Methods From Nov 2002 to Aug 2013,31 patients with PA/VSD had undergone right ventricle-pulmonary anastomasis to reconstruct RVOT for radical or palliative repair.Related echocardiography indexs including strain/rate etc.were used to evaluate the right heart function and the progress of the right heart valves regurgitation.Results There were 3 early hospital deaths.No later death during follow-up.The echocardiography suggested the pulmonary artery and tricuspid regurgitation were more serious,however,the right heart function was relatively fine.The regurgitation of tricuspid valve was positive correlation with duration of follow-up (P =0.016).Conclusion The right heart function in follow-up keeps relatively well,and tricuspid valve regurgitation needs a long-term follow-up.

Objective To compare the two different ways of right ventricular outflow tract(RVOT) reconstruction at repair of pulmonary atresia with ventricular septal defect,the direct RV-PA anastomosis and pericardial conduit to find the better way.Methods From Jun.2002 to Oct.2012,66 patients underwent pulmonary atresia with ventricular septal defect repair in our hospital,age at operation from 14 days to 272 months.Patients were divided into 2 groups according to the way of RVOT reconstruction.Group 1:31 of them,using direct RV-PA anastomasis,Group 2:35 of them,using pericardial conduit.Paired t test was used to evaluate the growth of pulmonary arteries.Chi-square test and Kaplan-Meier were used to calculate the postoperative mortality,reopemtion situation and survival time.Results There are 3 early hospital death in group 1 (9.7 ％),and 5 in group 2(14.3％),P =0.71.There is a significant difference between the two groups in restenosis rate of the RV-PA anastomasis and autologous pericardial conduit with pulmonary branch artery(Group 1:22.2％,Group 2:55.6％,P =0.01).The diameters of RV-PA anastomasis and the pulmonary artery branches in follow-up were significantly lager than the earlier diameters(P ＜ 0.05) in group 1.There is no growth on diameters of the pericardial conduit and pulmonary branches except the right pulmonary artery in follow-up in group 2.There is no significant difference between the two groups in later survival(P =0.30).Conclusion Both the direct anastomasis of RV-PA and pericardial conduit are available for RVOT reconstruction in pulmonary atresia with ventricular setal defect repair.There is lower incidence of RVOT and pulmonary stenosis and anastomosis absolutely has the ability for later growth in the former.
