Objective To analyze the impact of uterine septum on pregnancy and influencing factors on postopera-tive pregnancy. Methods 125 patients with septate uterus and bearing requirement who underwent TCRS were fol-lowed up to assess fertility outcome. The clinical data was retrospectively analyzed. Results Spontaneous abortion rate was 70.40%and 19.39%, live birth rates was 10.40%and 72.45 %in preoperation and postoperation respec-tively. The difference was statistically significant ( < 0.05). Spontaneous abortion rate in older than 35 years old group was significantly higher than that in younger than 35 years old group, but live birth rate was lower. There was no significant difference in different times of operation in uterine cavity, number of abortion and septum length and so on. Conclusions TCRS can significantly improve pregnancy outcome. The age has influence on postoperative pregnancy outcome. Abortion numbers, septum length, septal base width, intrauterine device (IUD) and hormone re-placement therapy (HRT) may have no effects.

Objective:
To investigate the survival status and influencing factors of HIV/AIDS patients after receiving highly active antiretroviral therapy(HAART)in Shangluo,Shaanxi Province,so as to provide evidence for improving the effect of HAART.
Methods:
HIV/AIDS patients who received HAART for the first time in Shangluo from 2010 to 2018 were investigated. Life table method was used to analyze the survival rate,mortality rate and median survival time of the subjects. A proportional hazards model was used to analyze the influencing factors for the survival time of HIV/AIDS patients.
Results:
A total of 286 HIV/AIDS patients were collected,and 27 of them died of AIDS. After HAART,the 1-year,cumulative survival rates of less than 1 year,4 years and 8 years were 93.95%,89.71% and 88.39%,respectively. The results of multivariate proportional hazards regression analysis showed that the patients aged 30 years when first received HAART had higher risk of death than those aged 18-29 years(RR:4.208-24.095,95%CI:1.219-79.491);patients with AIDS had higher risk of death than those with HIV(RR=38.590, 95%CI:15.451-96.382);patients by homosexual transmission(RR=3.425,95%CI:1.385-8.470)and non-sexual transmission(RR=10.299,95%CI:3.602-29.446)had higher risk of death than those by heterosexual transmission;patients with baseline CD4+T lymphocytes number of 200/μL and more(RR:0.133-0.170,95%CI:0.048-0.604)had lower risk of death than those with less than 200/μL.
Conclusions
The survival rate of HIV/AIDS patients in Shangluo after receiving HAART is relatively high. Age at the start of treatment,course of disease,route of infection and the number of CD4+T lymphocytes at baseline are the influencing factors of survival time.

Objective:To explore the influence of body mass index (BMI) changes on the doses to normal tissues and adverse reactions of the lower digestive system and urinary system in the brachytherapy for cervical cancer.Methods:Clinical data of 80 cervical cancer patients who received radical radiotherapy in our hospital from January 2020 to February 2021 were retrospectively analyzed. All patients received external beam radiation ± chemotherapy + brachytherapy. The delineation method of target areas and organs at risk (OAR) was determined based on the recommended scheme of GEC-ESTRO. The target areas included high risk (HR)-CTV and intermediate risk (IR)-CTV, and OAR consisted of rectum, sigmoid colon, bladder, and small intestine. The target area dose was evaluated by D 90% of the HR-CTV. The OAR volume dose was evaluated by using D2cm3. Correlation analysis was used to compare the dosimetric relationship between BMI and D2cm3, D1cm3 and D0.1cm3 in bladder, rectum, colon and small intestine. Logistic regression analysis was adopted to analyze the risk factors of acute and late adverse reactions in the lower gastrointestinal system and urinary system. Whether BMI was a risk factor was validated. Results:BMI was negatively correlated with the D2cm3, D1cm3 and D0.1cm3 of the small intestine ( P=0.034, 0.024, 0.034), and the correlation coefficients were -0.240, -0.255, and -0.241, respectively. Logistic regression analysis showed that BMI was not a risk factor for the occurrence of acute and late adverse reactions in the lower gastrointestinal system and urinary system. For every 1 Gy increase of D2cm3, D1cm3 and D0.1cm3 in the small intestine, the relative risk of acute adverse reactions in the lower gastrointestinal system was increased by 16.6%, 15.1%,and 12.7%, respectively. Conclusions:In brachytherapy for cervical cancer, there is a negative correlation between BMI and D2cm3, D1cm3 and D0.1cm3 of the small intestine. As the BMI of patients declines, the radiation dose to the small intestine shows an increasing trend, which may increase the risk of acute adverse reactions in the lower gastrointestinal system.

Objective:
To analyze the prognostic significance of TP53, Bcl-2, Bcl-6, Myc proteins expression by immunohistochemical method (IHC) in diffuse large B cell Lymphoma (DLBCL) .
Methods:
Clinical and pathologic data of 223 patients with DLBCL hospitalized in Zhejiang First Hospital from March 2009 to June 2015 were retrospectively analyzed.
Results:
The 223 cases, a median age of 56 years old with a male predominance, had shown a 39.0% of TP53 positive expression, 38.6% of Myc, 69.1% of Bcl-2, 56.5% of Bcl-6, and 22.7% of Myc/Bcl-2 double expression. According to Hans’ classification, 27.4% were GCB and 72.6% were non-GCB. With a median follow-up of 38 (2-97) months, the 3 and 5 years survival rates were 70% and 66% , respectively. By multivariate analysis, TP53 over-expression and Myc/Bcl-2 double expression were independently associated with poor outcomes. 3-year and 5-year overall survival were 59% and 57% for patients with TP53 positive, 77% and 71% for patients with TP53 negative expression. Patients with non-GCB subtype receiving chemotherapy combined with rituximab had a higher OS than those without rituximab. But rituximab did not improve the prognosis of patients with TP53 positive.
Conclusion
Myc/Bcl-2 double expression and TP53 over-expression are poor prognosis for DLBCL patients. Patients with Myc/Bcl-2 double expression have shorter OS. Patients with non-GCB subtype who received chemotherapy combined with rituximab have a better OS than those without rituximab. But rituximab does not improve the prognosis of patients with TP53 positive.
