Human immunodeficiency virus infection status and related factors among men who have sex with men in Jinhua City， Zhejiang Province from 2016 to 2021 / 上海预防医学

ObjectiveTo understand the human immunodeficiency virus（HIV） infection status and related factors by using the HIV/AIDS sentinel surveillance data of men who have sex with men（MSM） in Jinhua City， Zhejiang Province. MethodsSnowball sampling method was used to recruit MSM receiving HIV sentinel surveillance from 2016 to 2021.The inclusion criteria were aged 18 years old and above， reported having anal sex with man in recent 6 months. Questionnaire-based interviews were conducted on a one-on-one basis. Data including the characteristics of demography and ethology were collected. Five milliliter of blood samples were taken after the questionnaire. HIV and syphilis was screened. The time trend was analyzed with χ2 test. Multivariate logistic regression model was used to analyze the factors associated with HIV infection status among MSM. ResultsThe positive rate of HIV was 8.0% （127/1 597）， with an increasing trend （P=0.002）， but the linear correlation was weak（r=0.075）. The positive rate of syphilis was 5.2% （83/1 597）， with no significant difference （P=0.661）.The constituent ratios showed an increasing trend （P<0.05） in using condoms consistently， finding male sexual partners through Internet or dating software， having anal sex in the past week， using condoms every time during anal sex in the past 6 months， accepting prevention services of AIDS in the last year， and the overall awareness of AIDS related knowledge. Multivariate logistic regression analysis showed that who was from national minority （OR=2.27， 95%CI： 1.08‒4.73） and from other provinces （OR=1.68， 95%CI： 1.08‒2.62）， who failed to consistently use condoms every time during anal sex in the past six months （OR=3.03， 95%CI： 2.02‒4.54）， who never accepted prevention services of AIDS in the last year （OR=2.17，95%CI：1.44‒3.27）， who don’t know the knowledge of AIDS （OR=1.86， 95%CI： 1.12‒3.07）， and who was infected with syphilis （OR=2.35， 95%CI： 1.20‒4.61） were at higher risk for HIV infection among MSM. ConclusionThe positive rate of HIV remains at a certain level among MSM in Jinhua. High-risk groups such as the patients with syphilis infections and floating population from other provinces need to be paid close attention. It is suggested to further strengthen the promotion of the use of condoms， awareness of AIDS and syphilis， warning education and comprehensive intervention services.

Intravenous thrombolysis in patients with stroke warning syndrome: comparison with antiplatelet therapy / 国际脑血管病杂志

Objective:To investigate the efficacy and safety of intravenous thrombolysis and antiplatelet therapy in patients with stroke warning syndrome (SWS), as well as influencing factors of the outcome in patients with SWS.Method:Patients with SWS admitted to the 521 st Hospital of Ordnance Group from June 1, 2018 to December 31, 2023 were retrospectively included. Some patients were treated with ateplase intravenous thrombolysis, followed by oral antiplatelet therapy; some patients only received antiplatelet therapy. The main outcome measure was the modified Rankin Scale score at 90 days after onset, with a score of 0-2 defined as good outcome. Results:A total of 35 patients with SWS were included, including 26 males (74.3%) with an age of 58.29±11.06 years. Nineteen patients (54.3%) received intravenous thrombolysis, and 27 (77.1%) had good outcome at 90 days. There was no statistically significant difference in demographic, baseline data, and good outcome between the intravenous thrombolysis group and the antiplatelet therapy group. One patient had new stroke and one had transient ischemic attack in the intravenous thrombolysis group. There were statistically significant differences in ABCD2 score, systolic blood pressure, low-density lipoprotein cholesterol, fasting blood glucose, highest National Institutes of Health Stroke Scale (NIHSS) score at onset, and symptom duration between the good outcome group and the poor outcome group (all P<0.05). Conclusions:The efficacy of intravenous thrombolysis is similar to that of antiplatelet drugs alone in treating SWS. ABCD2 score, systolic blood pressure, low-density lipoprotein cholesterol, fasting blood glucose, highest NIHSS score at onset, and duration of symptoms may be influencing factors for the outcome of patients with SWS.

Efficacy of laparoscopic proximal gastrectomy with double-tract reconstruction versus laparoscopic total gastrectomy with Roux-en-Y reconstruction for early upper gastric cancer / 中华胃肠外科杂志

Objective: To compare clinical efficacy between laparoscopic radical proximal gastrectomy with double-tract reconstruction (LPG-DTR) and laparoscopic radical total gastrectomy with Roux-en-Y reconstruction (LTG-RY) in patients with early upper gastric cancer, and to provide a reference for the selection of surgical methods in early upper gastric cancer. Methods: A retrospective cohort study method was carried out. Clinical data of 80 patients with early upper gastric cancer who underwent LPG-DTR or LTG-RY by the same surgical team at the Department of General Surgery, the First Affiliated Hospital of Xi'an Jiaotong University from January 2018 to January 2021 were retrospectively analyzed. Patients were divided into the DTR group (32 cases) and R-Y group (48 cases) according to surgical procedures and digestive tract reconstruction methods. Surgical and pathological characteristics, postoperative complications (short-term complications within 30 days after surgery and long-term complications after postoperative 30 days), survival time and nutritinal status were compared between the two groups. For nutritional status, reduction rate was used to represent the changes in total protein, albumin, total cholesterol, body mass, hemoglobin and vitamin B12 levels at postoperative 1-year and 2-year. Non-normally distributed continuous data were presented as median (interquartile range), and the Mann-Whitney U test was used for comparison between groups. The χ(2) test or Fisher's exact test was used for comparison of data between groups. The Mann-Whitney U test was used to compare the ranked data between groups. The survival rate was calculated by Kaplan-Meier method categorical, and compared by using the log-rank test. Results: There were no statistically significant differences in baseline data betweeen the two groups, except that patients in the R-Y group were oldere and had larger tumor. Patients of both groups successfully completed the operation without conversion to laparotomy, combined organ resection, or perioperative death. There were no significant differences in the distance from proximal resection margin to superior margin of tumor, postoperative hospital stay, time to flatus and food-taking, hospitalization cost, short- and long-term complications between the two groups (all P>0.05). Compared with the R-Y group, the DTR group had shorter distal margins [(3.2±0.5) cm vs. (11.7±2.0) cm, t=-23.033, P<0.001], longer surgery time [232.5 (63.7) minutes vs. 185.0 (63.0) minutes, Z=-3.238, P=0.001], longer anastomosis time [62.5 (17.5) minutes vs. 40.0 (10.0) minutes, Z=-6.321, P<0.001], less intraoperative blood loss [(138.1±51.6) ml vs. (184.3±62.1) ml, t=-3.477, P=0.001], with significant differences (all P<0.05). The median follow-up of the whole group was 18 months, and the 2-year cancer-specific survival rate was 97.5%, with 100% in the DTR group and 95.8% in the R-Y group (P=0.373). Compared with R-Y group at postoperative 1 year, the reduction rate of weight, hemoglobin and vitamin B12 were lower in DTR group with significant differences (all P<0.05); at postoperative 2-year, the reduction rate of vitamin B12 was still lower with significant differences (P<0.001), but the reduction rates of total protein, albumin, total cholesterol, body weight and hemoglobin were similar between the two groups (all P>0.05). Conclusions: LPG-DTR is safe and feasible in the treatment of early upper gastric cancer. The short-term postoperative nutritional status and long-term vitamin B12 levels of patients undergoing LPG-DTR are superior to those undergoing LTG-RY.

@#AIM:To evaluate the effect of keratometry on the calculation accuracy of intraocular lens(IOL)diopter in patients with normal axial cataract.METHODS:Totally 157 cases(157 eyes)with age related cataract were collected in Kaifeng Central Hospital from June 2020 to June 2021. Patients were divided into 3 groups according to keratometry: group A(53 eyes)(K<42D), group B(55 eyes)(42D≤K≤46D), group C(49 eyes)(K>46D). The IOL diopter was calculated by SRK/T, Hoffer Q, Holladay 2, Haigis, Kane and Barrett Ⅱ formulas respectively. Subjective optometry was performed after 1mo operation. The average refractive prediction error(RPE)and mean absolute error(MAE)were calculated, and their differences were compared and analyzed.RESULTS:There were significant difference between RPE of each formula and 0D in groups A and C(<i>P</i><0.05), and Barrett Ⅱ formula was significantly different with SRK/T, Hoffer Q, Holladay 2 and Haigis formula(<i>P</i><0.01), but was no significantly different with Kane formula in RPE(<i>P</i>>0.01). There was no significant difference in RPE between group B and 0D(<i>P</i>>0.05). The ratio of Barrett Ⅱ formula in MAE≤0.5D in group A was significantly higher than SRK/T, Hoffer Q, Holladay 2 and Haigis formula(all <i>P</i><0.01), but there was no significant difference compared with Kane formula(<i>P</i>>0.01). In group B, there was no significant difference among Barrett Ⅱ formula and the other formulas in the ratio of MAE≤0.5D and ≤1.0D(all <i>P</i> >0.01). In group C, the ratio of SRK/T and Hoff Q formula in MAE≤0.5D was lower than Barrett Ⅱ formula(all <i>P</i><0.01), and there were no significant difference among Barrett Ⅱ formula and the other formulas in the ratio of MAE≤1.0D(<i>P</i> >0.01).CONCLUSION:If K<42D or K>46D before operation, the commonly used formulas will produce refractive error, but the accuracy of Kane and Barrett Ⅱ formulas are still higher than other formulas.

Influence of visceral lipids obesity on the early postoperative complications after radical gastrectomy / 中华胃肠外科杂志

Objective: To investigate the effect of visceral fat area (VFA) on the surgical efficacy and early postoperative complications of radical gastrectomy for gastric cancer. Methods: A retrospective cohort study method was used. Clinicopathological data and preoperative imaging data of 195 patients who underwent D2 radical gastric cancer surgery at the First Affiliated Hospital of Xi'an Jiaotong University from January 2014 to December 2017 were analyzed retrospectively. Inclusion criteria: (1) complete clinicopathological and imaging data; (2) malignant gastric tumor diagnosed by preoperative pathology, and gastric cancer confirmed by postoperative pathology; (3) no preoperative complications such as bleeding, obstruction or perforation, and no distant metastasis. Those who had a history of abdominal surgery, concurrent malignant tumors, poor basic conditions, emergency surgery, palliative resection, and preoperative neoadjuvant therapy were excluded. The VFA was calculated by software and VFA ≥ 100 cm2 was defined as visceral obesity according to the Japan Obesity Association criteria . The patients were divided into high VFA (VFA-H, VFA≥100 cm2, n=96) group and low VFA (VFA-L, VFA<100 cm2, n=99) group . The clinicopathological characteristics, surgical outcomes and early postoperative complications were compared between the two groups. Univariate and multivariate Logistic regression models were used to analyze the risk factors of early complications. Receiver operating characteristic (ROC) curve was used to analyze predictive values of VFA for early complications. Pearson's χ2 test was used to analyze the correlation between BMI and VFA. Results: There were no significant differences in terms of gender, age, American Society of Anesthesiologists physical status classification, preoperative comorbidities, preoperative anemia, tumor TNM staging, N staging, T staging and tumor differentiation, surgical method, extent of resection, and tumor location between the VFA-L group and the VFA-H group (all P>0.05). However, patients in the VFA-H group had higher BMI, larger tumor, lower rate of hypoalbuminemia and greater subcutaneous fat area (SFA) (all P<0.05). The VFA-H group presented significantly longer operation time and significantly less number of harvested lymph nodes as compared to the VFA-L group (both P<0.05). However, there were no significant differences in intraoperative blood loss, conversion to laparotomy and postoperative hospital stay (all P>0.05). Complications of Clavien-Dindo grade II and above within 30 days after operation were mainly anastomosis-related complications (leakage, bleeding, infection and stricture), intestinal obstruction and incision infection. The VFA-H group had a higher morbidity of early complications compared to the VFA-L group [24.0% (23/96) vs 10.1% (10/99), χ2=6.657, P=0.010], and the rates of anastomotic complications and incision infection were also higher in the VFA group [10.4% (10/96) vs. 3.0% (3/99), χ2=4.274, P=0.039; 7.3% (7/96) vs. 1.0% (1/99), P=0.033]. Multivariate logistic analysis showed that high BMI (OR=3.688, 95%CI: 1.685-8.072, P=0.001) and high VFA (OR=2.526, 95%CI: 1.148-5.559,P=0.021) were independent risk factors for early complications. The area under the ROC curve (AUC) of VFA for predicting early complications was 0.645, which was higher than that of body weight (0.591), BMI (0.624) and SFA (0.626). Correlation analysis indicated that there was a significantly positive correlation between BMI and VFA (r=0.640, P<0.001). Conclusion: VFA ≥ 100 cm2 is an independent risk factor for early complications after radical gastrectomy for gastric cancer.It can better predict the occurrence of above early postoperative complications.

The treatment group was treated with oral use of Recipe for Clearing Heat and Removing Dampness combined with external use of Butyl Flufenamate Ointment, and the control group was only treated with external use of Butyl Flufenamate Ointment. The treatment for the two groups covered 4 weeks. Before treatment and on treatment day 7, 14 and 28, scores of clinical symptoms, related skin barrier function indexes,and the serum level of cathepsin S(Cat S)in the two groups were observed. Results(1)On treatment day 14,28,the total effective rate in the treatment group was 84.8％, 89.1％,and that in the control group was 65.2％,71.7％ respectively,the difference being significant(P < 0.05).(2)On treatment day 7,14,28, the scores of clinical symptoms in the two groups were obviously decreased(P < 0.05 compared with those before treatment),and the decrease in the treatment group was superior to that in the control group (P < 0.05).(3) On treatment day 7,14,28,facial sebum secretin,skin water content,and transepidermal water loss(TEWL) of the treatment group were improved to various degrees compared with those of the control group,the differences being significnat(P < 0.05 or P < 0.01).(4)On treatment day 28,serum Cat S of the two groups was markedly decreased(P < 0.01 compared with that before treatment),and the decrease in the treatment group was superior to that in the control group (P < 0.01). Conclusion Recipe for Clearing Heat and Removing Dampness combined with Butyl Flufenamate Ointment exerts certain effect for the treatment of facial seborrheic dermatitis.

Treatment Progress of Traditional Chinese Medicine And Western Medicine on Regulating Vasa Vasorum for Atherosclerosis Vulnerable Plaque Stabilization / 世界科学技术-中医药现代化

The major clinical risk of atherosclerosis (AS) lesion is instability and vulnerability of plaque.Intraplaque vasa vasorum (VV) has structure defects with the characteristics of immature,irregular,fragile,and prone to extravasation and intraplaque hemorrhage due to the compromised structural integrity.It stimulates inflammatory reaction and provides channel for hemocyte and blood soluble composition entering into the plaque.Intraplaque VV can promote AS plaque formation and is closely related to the intraplaque hemorrhage,plaque rupture and occurrence of clinical cardiovascular events.In-depth study of VV function and key signaling pathways related to AS pathological process are promising to fundamentally prevent vulnerable plaque development,unstable plaque rupture and its complications.This article summarized the effect and mechanism of VV in pathological process of AS and related treatment,in order to provide theoretical basis for stabilization of AS vulnerable plaque.

Experimental Study of Si-Miao Yong-An Decoction Regulating Vasa Vasorum Remodeling in ApoE-/-Mice with Atherosclerosis Vulnerable Plague / 世界科学技术-中医药现代化

This study was aimed to observe the effect of Si-Miao Yong-An (SMYA) decoction intervention in atherosclerosis (AS) vulnerable plaque,and to further explore the action mechanism from the entry point of vasa vasorum (VV) neovascularization.Male ApoE-/-mice were randomly divided into the model group,simvastatin group and SMYA group.High-fat diet added 1.1％ L-methionine was fed for 8 weeks to establish the AS vulnerable plaque model.The C57BL/6 mice were used as control.After 8 weeks' continuous medication,mice were sacrificed.HE staining were used to observe the pathological changes of mice aorta;immunohistochemical staining was used to observe the VV density in AS plaque and aortic adventitia;macrophage infiltration in plaque was also detected;the blood-lipid changes of TC,TG,LDL-C and HDL-C were detected;western blot was used to detect essential proteins of HIF-1α-Apelin/APJ signal pathway.The results showed that SMYA decoction decreased the plaque area and the ratio of plaque area and lumen area,increased the minimum thickness of fibrous cap,which significantly improved the pathological feature of aortic plaque in mice.The function of increasing the minimum thickness of fibrous cap was obviously superior to simvastatin.SMYA decoction effectively suppressed the VV neovascularization and decreased the macrophage content.SMYA decoction effectively decreased the serum level of TC,TG and LDL-C;however,it had no effect on HDL-C.SMYA decoction decreased the protein expression of HIF-1α.Its function was obviously superior to simvastatin.SMYA decoction can down-regulate the protein expressions of Apelin,APJ,Phospho-MEK1/2 (Ser217/221),Phospho-p44/42 MAPK (Erk1/2) (Thr202/Tyr204) and Phospho-p70 S6 Kinase (Thr421/Ser424).It was concluded that SMYA decoction regulated the HIF-1α-Apelin/APJ signal pathway,suppressed VV neovascularization and stabilized AS vulnerable plaque.

Clinical Observation of Kouyanqing Granules in the Treatment of Chronic Periodontitis / 中国药房

OBJECTIVE:To observe therapeutic efficacy and safety of Kouyanqing granules for chronic periodontitis and it effects on inflammatory cytokine. METHODS:110 patients with chronic periodontitis were divided into control group(55 cases)and observa-tion group(55 cases). Control group accepted the periodontal basic treatment as oral hygiene instruction,supragingival scaling,subgin-gival scaling and root planning. Observation group was additionally given Kouyanqing granules 20 g orally,twice a day,on the basis of control group. Both groups were treated for 4 weeks. Clinical efficacies of 2 groups were observed as well as the levels of plaque in-dex(PLI),gingival index(GI),probing depth(PD),clinical attachment level(CAL),IL-17,IL-21,and the occurrence of ADR. RE-SULTS:Both groups completed the treatment,and no patient lost to follow up. Total response rate of observation group was significant-ly higher than that of control group,with statistical significance(P0.05). CONCLUSIONS:Based on routine treatment,Kouyanqing granules show significant therapeutic efficacy for chronic periodontitis, can significantly improve periodontal symptom and reduce inflammatory factor level,but do not increase the incidence of ADR.

Risk factors complicated cardiovascular and cerebrovascular diseases in patients with refractory hypertension / 心血管康复医学杂志

Objective: To explore risk factors for complicated cardiovascular and cerebrovascular diseases in patients with refractory hypertension (RH).Methods: Clinical data of 536 RH patients, who were treated in our hospital from Jun 2010 to Jul 2015, were retrospectively analyzed.According to presence of cardiovascular and cerebrovascular diseases or not, patients were divided into complication group (n=217) and pure RH group (n=319).Results: Compared with pure RH group, there were significant rise in percentages of drinking and smoking, hypertension course, mean arterial pressure (MAP), mean systolic blood pressure, pulse pressure, serum uric acid (SUA), creatinine (Cr), total cholesterol and low density lipoprotein cholesterol (LDL-C), and significant reductions in high density lipoprotein cholesterol (HDL-C) mean diastolic blood pressure and mean heart rate in complication group, P<0.01 all.Multi-factor unconditional Logistic regression analysis indicated that hypertension course, SUA,MAP, Cr and LDL-C levels were independent risk factors for complicated cardiovascular and cerebrovascular diseases in RH patients (OR=1.014~3.217, P<0.05 or <0.01).Conclusion: Hypertension course,MAP,Cr,SUA and LDL-C are independent risk factors for refractory hypertension.Enhancing their monitor, prevention and treatment are important to reduce incidence rates of cardiovascular and cerebrovascular complications in patients with refractory hypertension.
