Objective This article aims to investigate the association between hypertension and the risk of GSD by conducting a national multicenter study,a systematic review,and a meta-analysis.Methods The study was conducted in three stages.In the first stage,subjects were recruited for health examination in four hospitals in Chengdu,Tianjin,Beijing,and Chongqing,China,from 2015 to 2020,and the multivariate logistic regression analysis was used to investigate the association between hypertension and the risk of GSD in each center.In the second stage,Embase,PubMed,Wanfang Data,VIP,and CNKI databases were searched for related studies published up to May 2021,and a meta-analysis was conducted to further verify such association.In the third stage,the random effects model was used for pooled analysis of the results of the multicenter cross-sectional study and the findings of previous literature.Results A total of 633 948 participants were enrolled in the cross-sectional study,and the prevalence rate of GSD was 7.844%.The multivariate logistic regression analysis showed that hypertension was positively associated with the risk of GSD(P＜0.05).Subgroup analysis showed that there was no significant difference in the association between hypertension and GSD between individuals with different sexes,ages,and subtypes of GSD.A total of 80 articles were included in the systematic review and the meta-analysis,and the results showed that the risk of GSD was increased by 1.022 times for every 10 mmHg increase in diastolic pressure and 1.014 times for every 10 mmHg increase in systolic pressure.Conclusion Hypertension significantly increases the risk of GSD,and the findings of this study will provide a basis for the etiology of GSD and the identification of high-risk groups.

Objective:To explore the incidence and risk factors of parastomal hernia after colostomy.Methods:The retrospective cohort study was conducted. The clinicopathological data of 145 patients undergoing colostomy in Xinxiang Central Hospital from January 2015 to January 2019 were collected. There were 86 males and 59 females, aged(59±11) years. Patients received pelvic and abdominal computed tomography once every 6 months after colostomy to detect the occurrence of parastomal hernia. Measurement data with normal distribution were represented as Mean± SD, and the independent sample t test was used for comparison between groups. Measurement data with skewed distribution were represented as M(range). Count data were represented as absolute numbers, and chi-square test or Fisher exact probability was used for comparison between groups. Kaplan-Meier method was used to analyze the cumulative annual incidence of parastomal hernia. Logarithmic rank test was used to analyze the cumulative incidence based on clinical variables. COX proportional hazard regression model was used for univariate and multivariate analyses. Results:(1) Incidence of parastomal hernia after colostomy. All the 145 patients were followed up for 86(range, 60?108)months after colostomy, of which 46 cases had parastomal hernia and 99 cases had no parastomal hernia. There were significant differences in gender, age, body mass index (BMI) and chronic liver disease between patients with and without parastomal hernia after colostomy ( χ2=23.28, t=13.27, χ2=6.17, 5.82, P<0.05). (2) Annual cumulative incidence of parastomal hernia after colostomy. The 1-, 3-, and 5-year cumulative incidence of parastromal hernia after colostomy was 8.5%, 26.4% and 42.7%, respectively. When the follow-up time is more than 5 years, the incidence of parastromal hernia tended to be stable. The 5-year incidence of parastomal hernia after colostomy in female patients was higher than that in male patients (70.7% vs 20.3%, χ2=12.37, P<0.05). The 5-year incidence of parastomal hernia after colostomy in patients≥60 years old was higher than that in patients under 60 years old (49.8% vs 20.0%, χ2=10.52, P<0.05). The 5-year incidence of parastomal hernia after colostomy in patients with BMI >28 kg/m 2 was higher than that in patients with BMI ≤28 kg/m 2 (55.3% vs 33.2%, χ2=11.76, P<0.05). The 5-year incidence of parastomal hernia after colostomy in patients with chronic liver disease was higher than that in patients with non-chronic liver disease (45.2% vs 32.4%, χ2=15.32, P<0.05). (3) Analysis of risk factors for parastomal hernia after colostomy. Results of multivariate analysis showed that female, age >60 years old, BMI ≥28 kg/m 2 and chronic liver disease were independent risk factors for parastomal hernia after colostomy ( hazard ratio=2.70, 2.51, 1.85, 5.88, 95% confidence intervals as 1.39?6.74, 1.01?4.59, 1.02?4.87, 1.05?8.24, P<0.05). Conclusions:The incidence of parastomal hernia after colostomy is increasing year by year, and tends to be stable after 5 years. Female, age >60 years old, BMI≥28 kg/m 2, and chronic liver disease are independent risk factors for parastomal hernia after colostomy.

Objective: This study aimed to investigate the impact of molecular classification and PTEN, KRAS and PIK3CA gene mutation on the outcome of fertility-preserving treatment in the patients with endometrioid endometrial cancer (EEC) and endometrial atypical hyperplasia (EAH). Methods: This is a single-center retrospective study. A total of 135 patients with EEC and EAH receiving fertility-preserving treatment and molecular classification were reviewed. The distribution of the four types of molecular classification was described. The impact of non-specific molecular profile (NSMP), mismatch repair-deficiency (MMRd), and PTEN, KRAS and PIK3CA gene mutation on the outcome of fertility-preserving treatment was analyzed. Results: Of the patients analyzed, 86.7% (117/136) were classified as having NSMP; 14 (10.4%), MMRd; 1 (0.7%), POLEmut EAH; and 3 (2.2%), p53abn EEC. The patients having NSMP and MMRd achieved similar 16-, 32-, and 48-week complete response rates. The patients harboring tier I and tier II PTEN mutations (PTENmut-Clin) achieved lower cumulative 32-week CR rates than those with PTEN-others (without PTENmut-Clin) (22/47, 46.8% vs. 50/74, 67.6%; p=0.023; odds ratio=0.422; 95% confidence interval [CI]=0.199–0.896). Insulin-resistance (hazard ratio [HR]=0.435; 95% CI=0.269–0.702; p=0.001) and PTENmut-Clin (HR=0.535; 95% CI=0.324–0.885; p=0.015) were independent negative predictors for lower 32-week CR rates. Conclusion PTENmut-Clin is an independent risk factor for unfavorable fertility-preserving treatment outcomes in the patients with EEC and EAH. The patients with MMRd receiving fertility-preserving treatment achieved outcomes similar to those of the patients with NSMP. The molecular profiles might guide fertility-preserving treatment in the prognosis and clinical decisions.

Objective:To investigate the clinical efficacy of Danggui Zicao ointment on diabetic pruritus caused by heat and wind in blood. Methods:A total of 197 patients with diabetic pruritus caused by heat and wind in blood who received treatment in Jinhua Hospital of Traditional Chinese Medicine from November 2020 to March 2022 were included in this randomized controlled study. They were randomly divided into a control group ( n = 99) and an observation group ( n = 98). Based on basic hypoglycemic treatment, the control group was given oral levocetirizine hydrochloride tablets, while the observation group was externally given Danggui Zicao ointment. Both groups were treated for 4 successive weeks. Pre- and post-treatment 12-Item Pruritus Severity Scale (12-PSS) score and clinical efficacy were compared between the two groups. Results:After 4 weeks of treatment, the 12-PSS score in each group significantly decreased compared with that before treatment ( t = 18.09, 11.31, both P < 0.05). The 12-PSS score in the observation group was (7.72 ± 1.64) points, which was significantly lower than (9.35 ± 2.18) points in the control group ( t = 3.52, P < 0.05). The total effective rate in the observation group was 87.8% (86/98), which was significantly higher than 76.8% (76/98) in the control group ( χ2 = 4.06, P < 0.05). Conclusion:Danggui Zicao ointment can effectively improve the clinical symptoms of patients with diabetic pruritus caused by heat and wind in blood, improve quality of life, and deserves clinical promotion.

Objective:To explore the efficacy and safety of blinatumomab in treatment of relapsed/refractory B-cell acute lymphoblastic leukemia (B-ALL).Methods:The data of 8 patients with relapsed/refractory B-ALL treated with blinatumomab in Shanghai Zhaxin Traditional Chinese and Western Medicine Hospital from September 2020 to December 2021 were retrospectively analyzed, and their clinical characteristics, overall survival, lymphocyte subsets, cytokines, tandem transplantation and adverse reactions were analyzed.Results:The median follow-up time of 8 patients was 143 d (range: 41-534 d). Five of the 8 patients were alive; among them, 4 of 6 patients assessed to be in minimal residual disease (MRD)-negative complete remission (CR) and 1 of 2 patients assessed to be in non-remission at the time of belintuzumab discontinuation were alive. The median duration of treatment with belintuzumab was 28 d (10-56 d), and it was 23 d (10-56 d) for patients with MRD-positive at baseline and 28 d (25-31 d) for the 4 non-remission patients. Six patients achieved MRD-negative CR after treatment, of which 4 were assessed as MRD-positive at baseline and 2 were assessed as non-remission at baseline. All 4 patients with MRD-positive CR achieved MRD-negative CR after treatment with belintuzumab, including 1 patient with Philadelphia chromosome-positive (Ph +) ALL bridged to autologous hematopoietic stem cell transplantation, and 1 patient with Ph + ALL and 1 patient with Ph - ALL received sequential allogeneic hematopoietic stem cell transplantation and had persistent MRD-negative CR. Two of the 4 non-remission patients achieved MRD-negative CR after treatment with belintuzumab, including 1 patient with Ph + ALL bridged to autologous hematopoietic stem cell transplantation, and 1 patient with Ph - ALL received sequential allogeneic hematopoietic stem cell transplantation, and the 2 patients had persistent MRD-negative CR. Leukocyte counts and neutrophils decreased in both MRD-positive CR and non-remission patients after receiving belintumomab. The proportion and absolute number of CD3 + T and CD3 + CD8 + T lymphocytes in patients with MRD-positive CR were higher than those in patients without remission, and both decreased after drug administration. Median interleukin-6 (46.23, 1.42 pg/ml), interleukin-8 (17.85, 2.10 pg/ml), interleukin-10 (7.43, 1.49 pg/ml) and interferon-γ (11.82, 0.39 pg/ml) levels were elevated in MRD-positive CR and non-remission patients at week 3 of treatment. Grade 1 cytokine release syndrome occurred in 1 case with clinical manifestations of fever, which improved after drug suspension. Three cases developed infections, 2 of which were pulmonary and 1 of which was upper respiratory tract infection. No immune effector cell-associated neurotoxic syndrome was observed. Conclusions:Belintumomab is effective for MRD clearance in relapsed/refractory B-ALL with manageable adverse reactions, providing an effective therapeutic option for bridging hematopoietic stem cell transplantation to prolong the survival of patients.

Objective: To compare the effects and safety of dydrogesterone (DG) and medroxyprogesterone acetate (MPA) on the treatment in patients with endometrial hyperplasia without atypia (EH). Methods: This was a single-center, open-label, prospective non-inferior randomized controlled phase Ⅲ trial. From February 2019 to November 2021, patients with EH admitted to the Obstetrics and Gynecology Hospital of Fudan University were recruited. Enrolled patients were stratified according to the pathological types of simple hyperplasia (SH) or complex hyperplasia (CH), and were randomised to receive MPA or DG. Untill May 14, 2022, the median follow-up time after complete response (CR) was 9.3 months (1.1-17.2 months). The primary endpoint was the 6-month CR rate (6m-CR rate). The secondary endpoints included the 3-month CR rate (3m-CR rate), adverse events rate, recurrence rate, and pregnancy rate in one year after CR. Results: (1) A total of 292 patients with EH were enrolled in the study with the median age of 39 years (31-45 years). A total of 135 SH patients were randomly assigned to MPA group (n=67) and DG group (n=68), and 157 CH patients were randomly assigned to MPA group (n=79) and DG group (n=78). (2) Among 292 patients, 205 patients enrolled into the primary endpoint analysis, including 92 SH patients and 113 CH patients, with 100 patients in MPA group and 105 in DG group, respectively. The 6m-CR rate of MPA group and DG group were 90.0% (90/100) and 88.6% (93/105) respectively, and there were no statistical significance (χ²=0.11, P=0.741), with the rate difference (RD) was -1.4% (95%CI:-9.9%-7.0%). Stratified by the pathology types, the 6m-CR rate of SH patients was 93.5% (86/92), and MPA group and DG group were respectively 91.1% (41/45) and 95.7% (45/47); and the 6m-CR rate of CH patients was 85.8% (97/113), and MPA group and DG group were 89.1% (49/55) and 82.8% (48/58) respectively. The 6m-CR rates of the two treatments had no statistical significance either (all P>0.05). A total of 194 EH patients enrolled into the secondary endpoint analysis, including 88 SH patients and 106 CH patients, and 96 patients in MPA group and 98 in DG group, respectively. The 3m-CR rate of SH patients were 87.5% (77/88), while the 3m-CR rates of MPA group and DG group were 90.7% (39/43) and 84.4% (38/45), respectively; the 3m-CR rate of CH patients was 66.0% (70/106), and MPA group and DG group had the same 3m-CR rate of 66.0% (35/53). No statistical significance was found between the two treatments both in SH and CH patients (all P>0.05). (3) The incidence of adverse events between MPA group and DG group had no statistical significance (P>0.05). (4) A total of 93 SH patients achieved CR, and the cumulative recurrence rate in one year after CR were 5.9% and 0 in MPA group and DG group, respectively. While 112 CH patients achieved CR, and the cumulative recurrence rate in one year after CR were 8.8% and 6.5% in MPA group and DG group, respectively. There were no statistical significance between two treatment groups (all P>0.05). Among the 93 SH patients, 10 patients had family planning but no pregnancy happened during the follow-up period. Among the 112 CH patients, 21 were actively preparing for pregnancy, and the pregnancy rate and live-birth rate in one year after CR in MPA group were 7/9 and 2/7, while in DG group were respectively 4/12 and 2/4, and there were no statistical significance in pregnancy rate and live-birth rate between the two treatment groups (all P>0.05). Conclusions: Compared with MPA, DG is of good efficacy and safety in treating EH. DG is a favorable alternative treatment for EH patients.

OBJECTIVE: To investigate the association between short-term exposure to indoor total volatile organic compounds (TVOC) and nocturnal heart rate variability (HRV) among young female adults. METHODS: This panel study recruited 50 young females from one university in Beijing, China from December 2021 to April 2022. All the participants underwent two sequential visits. During each visit, real time indoor TVOC concentration was monitored using an indoor air quality detector. The real time levels of indoor temperature, relative humidity, noise, carbon dioxide and fine particulate matter were monitored using a temperature and humidity meter, a noise meter, a carbon dioxide meter and a particulate counter, respectively. HRV parameters were measured using a 12-lead Holter. Mixed-effects models were used to evaluate the association between the TVOC and HRV parameters and establish the exposure-response relationships, and two-pollutant models were applied to examine the robustness of the results. RESULTS: The mean age of the 50 female subjects was (22.5±2.3) years, and the mean body mass index was (20.4±1.9) kg/m². During this study, the median (interquartile range) of indoor TVOC concentrations was 0.069 (0.046) mg/m³, the median (interquartile range) of indoor temperature, relative humidity, carbon dioxide concentration, noise level and fine particulate matter concentration were 24.3 (2.7) ℃, 38.5% (15.0%), 0.1% (0.1%), 52.7 (5.8) dB(A) and 10.3 (21.5) μg/m³, respectively. Short-term exposure to indoor TVOC was associated with significant changes in time-domain and frequency-domain HRV parameters, and the exposure metric for most HRV parameters with the most significant changes was 1 h-moving average. Along with a 0.01 mg/m³ increment in 1 h-moving average concentration of indoor TVOC, this study observed decreases of 1.89% (95%CI: -2.28%, -1.50%) in standard deviation of all normal to normal intervals (SDNN), 1.92% (95%CI: -2.32%, -1.51%) in standard deviation of average normal to normal intervals (SDANN), 0.64% (95%CI: -1.13%, -0.14%) in percentage of adjacent NN intervals differing by more than 50 ms (pNN50), 3.52% (95%CI: -4.30%, -2.74%) in total power (TP), 5.01% (95%CI: -6.21%, -3.79%) in very low frequency (VLF) power, and 4.36% (95%CI: -5.16%, -3.55%) in low frequency (LF) power. The exposure-response curves showed that indoor TVOC was negatively correlated with SDNN, SDANN, TP, and VLF when the concentration exceeded 0.1 mg/m³. The two-pollutant models indicated that the results were generally robust after controlling indoor noise and fine particulate matter. CONCLUSION Short-term exposure to indoor TVOC was associated with significant negative changes in nocturnal HRV of young women. This study provides an important scientific basis for relevant prevention and control measures.

Objective: To investigate the nutritional status and examine its association with feeding among infants at ages of 6 to 24 months in Xinjiang Uygur Autonomous Region, so as to provide the evidence for improving malnutrition among infants. Methods: Infants at ages of 6 to 24 months participating in physical examinations in Urumqi City and Moyu County from January to December 2021 were enrolled. Participants' gender, age, birth status, place of residence and maternal education level were collected through questionnaire surveys, and infants' feeding was evaluated using Infant and Child Feeding Index (ICFI). Age-specific height and body weight and height-specific body weight were calculated, and nutritional status was evaluated using Z score. The association between ICFI and malnutrition was evaluated using a multivariable logistic regression model. Results : A total of 1 013 infants were surveyed, including 557 boys (54.99%) and 456 girls (45.01%). The participants included 545 infants at ages of 12 to 24 months (53.80%), 969 full-term infants (95.66%), and 617 infants with qualified ICFI scores (60.91%). The prevalence of malnutrition was 8.59% among participants. Multivariable logistic regression analysis showed that infants with qualified ICFI score had a lower risk of malnutrition (OR=0.538, 95%CI: 0.327-0.883) after adjustment for age, birth status, place of residence, maternal education level and monthly household income. Conclusion The prevalence of malnutrition is low among infants at ages of 6 to 24 months in Xinjiang Uygur Autonomous Region, and infants with qualified feeding have a reduced risk of malnutrition.
