Objective:The process of myocardial infarction is generally characterized by the activation of host immune cells and the occurrence of inflammation. However, it is unknown which immune cells are preferentially activated and participated into the progression of myocardial infarction. Methods:A total of 55 patients with myocardial ischemia including 13 of stable angina ( SA) ,25 of unstable angina (UA) and 17 of acute myocardial infarction (AMI) as well as 12 of healthy controls (HCs) were enrolled in the study. The frequency and the immune activation marker CD38 expression by peripheral CD3 T cells,CD4 T cells,CD8 T cells,CD4+NKT cells, CD4- NKT cells, CD3-CD56+ NK cells and B cells were comprehensively analyzed. Results:There was no significant difference in the frequencies of these immune cell subsets in peripheral blood among these four groups. Importantly,it was found that CD38 expression was significantly increased on CD8 T cells,NKT cells and NK cells in patients with acute coronary syndromes ( ACS) including UA and AMI patients as compared with those in SA and HC subjects. These data indicated that multiple immune cells were activated in ACS patients,which were possibly participated into the pathogenesis of ACS. Conclusion:The activation of multiple immune cells was closely associated with the progression and outcome in ACS patients. This study provides immune hyper-activation mechanism underlying the development of ACS and may favor for finding a novel immune marker to predict the progression of ACS.

OBJECTIVE: To identify long-term outcomes and safety of transplantation of autologous peripheral blood stem cells (PBSC) for treating dilated cardiomyopathy.METHODS: A total of 38 cases with dilated cardiomyopathy received treatment at the Department of Cardiology, Guangdong General Hospital of Chinese People's Armed Police Forces, were selected, including 26 males and 12 females, aged 42-72 years, mean aged 56 years. Based on given standard therapy, 38 patients divided randomly into the transplantation group (n=20) and the control group (n=18). Patients in the transplantation group were received recombinant human granulocyte colony-stimulating factor (rhG-CSF) 300 ug/d once per day for 5 days to mobilize stem cells. At day 6, PBSC were collected with blood-cells separator and were transplanted through intracoroary way. The routine medication was performed in the control group. Blood routine test, hepatic function, renal function, glucose, triglyeride (TG), cholesterol, low density cholesterol (C-LDL), high density cholest- erol (C-HDL), uric acid (UA), creatine kinase (CK), isoenzyme of creatine kinase (CK-MB) and high sensitive C-reactive protein (hsCRP) were measured before and at months 6 and 12 after transplantation. All patients also received ultrasonic echocardiography, ECG Holter monitor and six-minute-walk test before and at 12 and 24 months after the procedure. Survival rate and incidence rate of heart incidents were compared. The study end-point was death from any cause. RESULTS: All patients received a 12-24 month follow-up with mean (18±6) months. One patient in the transplantation group received mitral valve replacement. One patient of the transplantation group and 2 of the control group died due to refractory heart failure. The blood routine test and biochemical indicators of the transplantation group had no significant differences among 6 months and 12 months after transplantation compared with control and pre-transplantation (P > 0.05). Six-minute-walking distance in the transplantation group significantly increased at 12 months after transplantation than pre-transplantation level, which was also higher than that of control patients (P < 0.05). The left ventricular ejection fraction (LVEF) was increased (P < 0.01). The left ventricular diastolic diameter (LVDd) decreased significantly in the transplantation group (P < 0.01). In the control group, improvement in LVEF and LVDd were observed, but there was no significant difference (P > 0.05). After 24 months of follow-up, the above-mentioned indexes had not improved in the transplantation group without significant differences. No malignant arrhythmias and severe side effects could be observed around transplantation and during 24 months follow-up. Survival was similar between the two groups during 24 months follow. CONCLUSION: Transplantation of mobilized autologous PBSC might be a safe and effective method for the treatment of dilated cardiomyopathy, which may improve the ventricular systolic function in a short-term, however, the long-term effects still uncertain.

Objective: To investigate the epidemiological characteristics of hemorrhagic fever with renal syndrome (HFRS) in Shaoxing City from 2006 to 2022, so as provide insights into improvements of the HFRS control strategy. Methods: Data pertaining to HFRS cases in Shaoxing City from 2006 to 2022 were captured from the Surveillance System of China Information System for Disease Control and Prevention. The temporal, population and regional distributions of HFRS were analyzed using the descriptive epidemiological method, and the trends in incidence of HFRS were evaluated using annual percent change (APC). Results: Totally 1 022 HFRS cases were reported in Shaoxing City from 2006 to 2022, with annual average incidence of 1.22/105 and three deaths. The incidence of HFRS appeared a tendency towards a decline in Shaoxing City from 2006 to 2022 (APC=-11.101%, t=-9.930, P<0.001), and the incidence of HFRS peaked from May to June and from November to January of the next year. A higher incidence of HFRS was seen in men than in women (1.76/105 vs. 0.68/105; χ2=201.361, P<0.001). There were 714 HFRS cases at ages of 30 to 59 years (69.86%), and farmers were the predominant occupation (78.18%). The three counties with the largest number of HFRS cases included Zhuji (366 cases), Xinchang (263 cases) and Shengzhou (134 cases). The incidence of HFRS was lower in urban districts (Yuecheng, Keqiao and Shangyu) than in counties (Zhuji, Shengzhou and Xinchang) (0.58/105 vs. 1.96/105; χ2=326.880, P<0.001). Conclusion The incidence of HFRS appeared a tendency towards a decline in Shaoxing City from 2006 to 2022, and the incidence was high in late spring, early summer and winter. The HFRS cases were mainly males, young and middle-aged people, and farmers, and predominantly distributed in counties. Targeted control measures are needed.

Objective: To explore the causal association between dietary components (carbohydrate, fat, protein, and sugar) and 119 genera of known gut microbiota using Mendelian randomization (MR) methods. Methods: Genome-wide association study (GWAS) data for dietary components were collected from the DietGen, while GWAS data for gut microbiota were collected from the MiBioGen. Single nucleotide polymorphism (SNP) loci associated with the four dietary components were used as instrumental variables, and 119 known gut microbiota genera were used as the outcomes. MR analysis was performed using inverse variance weighted (IVW) method. Heterogeneity was evaluated using Cochran's Q test, horizontal pleiotropy and exclude outliers were tested using MR-Egger regression and MR-PRESSO test. Common genetic pleiotropic genes between dietary components and gut microbiota were identified by MAGMA and PLACO analyses. Results: The MR analysis revealed causal associations between carbohydrates and 4 gut microbiota genera, fats and 14 genera, proteins and 14 genera, and sugars and 11 genera (all P<0.05). The MR-Egger regression analysis showed no horizontal pleiotropy among the selected SNPs, and the MR-PRESSO test did not identify any outliers (all P>0.05). The MAGMA and PLACO analyses revealed that 74.42% (32/43) of the causal associations had pleiotropic genes, with 1 to 10 pleiotropic genes identified. Multiple causal association groups shared the same pleiotropic genes. Conclusion There are potential genetic and causal associations between dietary components and gut microbiota.

OBJECTIVE To study clinical characteristics of liver failure with fungal infections in the elderly patients and risk factors associated with treatment failure.METHODS Eighty four elderly patients with liver failure followed by fungal infections since 1986 were divided into two groups: effective group and ineffective group.RESULTS The common pathogens were Candida albicans(58.33%),Aspergillus fumigatus(9.52%) and Candida tropicalis(8.33%).The lungs(43.88%),mouth(32.65%),intestinal tract(9.18%) and blood(5.10%) were the main sites of fungal infection.Among them after treatment,35 cases(41.67%) were effective compared with 49 cases(58.33%) ineffective.The risk factors for treatment failure included age,complication with multiple organ dysfunction syndrome(MODS) and aspergillosis.In multivariate analysis,we found MODS in patients was an independent factor in predicting the prognosis.CONCLUSIONS To improve the treatment outcome,important measures include preventing infection,enhancing the treatment of liver failure,monitoring and supporting multiple organs: heart,brain,lungs and kidneys,and promptly rational administration of antifungal agents in elderly patient with liver failure.

OBJECTIVE To study the feature of liver disease and liver failure complicated with fungous infection. METHODS The patients with liver disease complicated with fungous infection were collected form 1986 to 2005. The time was divided into four stages:from 1986 to 1990,from 1991 to 1995,from 1996 to 2000 and from 2001 to 2005. All patients with liver failure complicated with fungous infection in different stages were investigated for the incidence,the use of antibiotics and corticosteroids,the category and site of fungous infection and prognosis. RESULTS End-stage liver disease accounted for 82.6% and HBV infection was the main etiology in 475 cases of fungous infection. Fungous infection occurred mainly in hospital. Hospital acquired infection and community acquired infection were similar in different stages. The use of antibiotics and corticosteroids accounted for 88.8% and 48% in all patients before fungous infection,respectively. The use of antibiotics had no difference and the use of corticosteroids decreased in different stages. Candida were the main infection strains and the lungs and pharynx oralis were the main infection sites. The rate of healing and improvement of fungous infection and underlying diseases increased year by year. Healing and improvement rate of underlaying disease positively correlated with that of fungous infection. CONCLUSIONS End-stage liver disease patients are susceptible to fungous infection and Candida are the common infection strains. Lungs and pharynx oralis are the common infection sites. Anti-fungous therapy is important in the treatment of liver failure complicated with fungous infection.

Objective To study the effects of neonatal bilateral and unilateral early sucking on the secretion time and the amount of colostrum.Methods A total of 300 cases with normal full-term delivery and nipple condition were selected and randomly divided into two groups:bilateral early sucking group and unilateral early sucking group.Women in the two groups were assisted by a midwife within 1 h after birth to implement early suction,with women of bilateral early sucking receiving breast sucking 15 minutes on each side and unilateral early sucking group 30 minutes just on one side.Maternal lactation′s initiating time and amount of lactation of two groups after postpartum 6 hours,24 hours,48 hours and 72 hours were analyzed.Results There was no difference of lactation initiating time in bilateral early sucking group and unilateral early sucking group (P >0.05).After 6 hours,lactation in the 2 groups had no difference (P >0.05).After 24 hours,48 hours and 72 hours,number of women with sufficient lactation in bilateral early sucking group was greater than unilateral early sucking group (P <0.05).Conclusions Bilateral early sucking is more favorable than unilateral early sucking postpartum for lactation amount.

【Objective】 To explore the effect of Lactobacillus rhamnosus on postpartum depression （PPD） and its potential mechanism. 【Methods】 The mouse model of PPD was established by using dexamethasone sodium phosphate during pregnancy. At the end of adaptive feeding， 50 pregnant female mice were randomly divided into low-dose group （group Ⅰ）， high-dose group （Group Ⅱ）， positive control group （Group Ⅲ）， model control group （Group IV）， and blank control group （Group Ⅴ）. The mice in Group Ⅰ and Group II were given Lactobacillus rhamnosus 1×10⁷ and1×10⁸CFU（kg·d）. The mice in Group Ⅲ were given 1.8 mg /（kg·d） paroxetine， and the mice in Groups IV and V were given the same amount of normal saline for 4 weeks. The 24-hour food consumption test， open field test and sugar water consumption test were used to detect the behavior of mice in each group. The concentrations of 5-hydroxytryptamine （5-HT）， norepinephrine （NE）， and dopamine （DA） were determined by RP-HPLC. The changes in Enterococcus faecalis， Bifidobacterium， Lactobacillus and Escherichia coli in the cecum of mice were detected by Real-time fluorescence quantitative PCR （RT-qPCR）. 【Results】 Before modeling， there were no significant differences in food intake， weight change rate， open field moving distance and speed， and percentage of sugar consumption among the groups （P>0.05）. After modeling， there was no significant difference in food intake or weight change rate among the five groups， but the open field moving distance， moving speed and percentage of sugar preference were significantly reduced （P<0.05）. After intervention with Lactobacillus rhamnosus， compared with Group Ⅳ， the depression-like behavior in Group Ⅰ and Group Ⅱ mice was improved； the weight change rate， open field moving distance and speed， percentage of sugar preference， and monoamine neurotransmitter concentration in Group I and Group Ⅱ were significantly increased compared with those in Group Ⅳ （P<0.05）， while Enterococcus faecalis， Escherichia coli and lactobacillus were significantly decreased （P<0.05）， and Bifidobacterium had an upward trend， but without significant difference. There was no significant change in food intake. 【Conclusion】 Lactobacillus rhamnosus can improve the depression-like behavior， affect monoamine neurotransmitters in mice， and regulate intestinal flora， which provides a new direction for studies on postpartum depression.
