ABSTRACT
【Objective】 To analyze the changes of gut microbes in patients with postpartum depression so as to explore the relationship between postpartum depression and gut microbes. 【Methods】 A total of 60 postpartum subjects were recruited to participate in this study. The depression status of the participants was scored using the Edinburgh Postpartum Depression Scale (EPDS). Those with a score ≥13 were included in the postpartum depression group (PPD group), while those with a score less than 13 were included in the postpartum healthy control group (PPHC group). The feces of these 60 subjects were collected, and the fecal whole genome DNA was extracted for 16S rDNA sequencing. The data of changes in the bacterial diversity between the groups were obtained, and the possible correlation between the changes of intestinal microbes and postpartum depression was analyzed. 【Results】 The number of microorganisms in PPD patients was significantly reduced (P<0.001); the Chao1 index (P<0.001) and ACE index (P<0.001) of α diversity decreased significantly. There were also significant differences in β diversity between the two groups. Analysis of the bacteria in the groups showed that Acetanaerobacterium, Adlercreutzia, Allobaculum, Alloprevotella, Bifidobacterium, Christensenella, Escherichia, Eubacterium, Faecalicatena, Fusobacterium, Haemophilus, Intestinimonas, Lactobacillus, Megamonas, Monoglobumus, Muribaculum, Oscillospira, Paraprevotella, Streptococcus, Raoultibacter, Ruminococcus and Stomatobaculum were significantly enriched in PPHC group. In contrast, Kineothrix, Lachnoclostridium, Acinetobacter, Aquisphaera, Enterococcus, and Mucispirillum were enriched in PPD group. RDA/CCA analysis showed that EPDS was positively correlated with Prevotella, Kineothrix, and Alistipes, but negatively correlated with Lachnospira. 【Conclusion】 This study found that the intestinal flora of patients with postpartum depression was significantly disrupted, and there was a correlation between the intestinal flora and postpartum depression symptom score. Therefore, intestinal microbial markers may contribute to the diagnosis and treatment of patients with postpartum depression.
ABSTRACT
Objective:To introduce a newly modified surgical approach and explore the clinical efficacy of en bloc kidney transplantation from deceased infant donors to adults.Methods:Four cases of en bloc kidney transplantation from deceased infant donor to adult were performed with a new modified surgical approach in renal transplantation and dialysis center of the Second People's Hospital of Shanxi Province from January 2017 to September 2019. All 4 cases were cardiac death donors. There were 3 males and 1 female donors, aged (54 ± 22.69) d and weighing (5.6 ± 0.79) kg. There were 1 male and 3 female recipients, aged (41.5 ± 5.97) years and weighing (45 ± 3.56) kg. For lowering operative difficulties and preventing hemodynamic disturbances, bilateral kidneys were sutured and fixed during trimming. Then end-to-side anastomosis was performed between donor kidney abdominal aortic valve and recipient external iliac artery and between donor renal inferior vena cava valve and recipient external iliac vein.Results:All operations were successful without vascular or urinary complication. The average duration of donor kidney repair was 20 min and the average duration of transplantation 68.75 min. The functions of transplanted kidney recovered well during a follow-up period of 12 months. The long-term survivals of recipient and transplanted kidney were satisfactory.Conclusions:The newly modified surgical approach of en bloc kidney transplantation from deceased infant donor to adult has optimized operative handling. With a higher success rate, vascular complications are lowered. A wider popularization is recommended.
ABSTRACT
OBJECTIVE@#To investigate the effect of glucagon-like peptide 1 receptor agonists (GLP-1RAs) on body fat redistribution and muscle mass in overweight/obese patients with type 2 diabetes (T2DM).@*METHODS@#We retrospectively analyzed the data of 76 patients with body mass indexes (BMI)≥24 kg/m, who had an established diagnosis of T2DM in our department between December, 2014 and September, 2015. We divided these patients according to their BMI in overweight group (BMI of 24-27.9 kg/m, =14), obese group (BMI of 28-31.9 kg/m, =35) and severely obese group (BMI≥32 kg/m, =27). All the patients received treatment with GLP-1RAs (Exenatide or Liraglutide) for 3.0 to 29.0 weeks (mean 8.9 weeks), and their blood glucose, HbA1c and serum lipids were analyzed. For each patient, the fat and muscle masses were analyzed using a human body composition analyzer (JAWON-IOI353, Korea) before and after GLP-1RAs treatment.@*RESULTS@#Treatment with GLP-1RAs significantly decreased BMI and visceral adiposity index (VAI) in all the patients in the 3 groups ( < 0.05). The treatment significantly decreased the body weight in the overweight group and obese group by 2.70 kg (0.60-4.95 kg) and 2.65 kg (1.45-6.40 kg), respectively ( < 0.05), and significantly decreased the waist-to-hip ratio (WHR) in the overweight group ( < 0.05). The obese and severely obese patients showed significantly decreased percentage body fat (including both subcutaneous and visceral fat) and increased muscle mass after the treatment ( < 0.05). Compared with those in the overweight group, the percentage body fat and VAI were significantly decreased in the obese group after the treatment ( < 0.05), and the percentage of subcutaneous fat reduced and the muscle ratio increased more obviously in the obese and severely obese patients ( < 0.05).@*CONCLUSIONS@#GLP-1RAs treatment can significantly lower BMI and improve body fat distribution in obese patients with T2DM, especially in patients with a greater BMI.

OBJECTIVE@#To investigate the effects of exendin-4 on hepatic lipid metabolism, fibrosis and oxidative stress in mice with streptozotocin (STZ)-induced diabetes and explore the underlying mechanisms.@*METHODS@#C57BL/6J mice were fed with high-fat diet (HFD) for 4 weeks and received intraperitoneal injections of 120 mg/kg STZ to induce diabetes. After successful modeling, the mice were randomized into diabetic control group and exendin-4 treatment group (DM+E4), and in the latter group, the mice were given a daily dose of 1 nmol/kg of exendin-4 for 8 weeks. The changes in the body weight (BW) and random blood glucose (RBG) in the mice were recorded. The mRNA expressions of the genes related with liver lipid metabolism, fibrosis and oxidative stress were analyzed using RT-PCR, and the structural changes of the liver tissues were observed with HE, Sirius red and oil red O staining; the expressions of TGF-β1, Nrf2 and HO-1 proteins in the liver tissues were detected using Western blotting.@*RESULTS@#The diabetic mice showed significantly higher RBG levels and BW with obvious lipid deposition, fibrosis and oxidative stress in the liver as compared with the normal control mice ( < 0.001). Exendin-4 treatment of the diabetic mice did not significantly lessened liver lipid deposition but obviously reduced the levels of RBG and TG ( < 0.05), lowered the expression levels of liver fibrosis-related genes TGF-β, -SMA and Col-Ⅰ ( < 0.05), increased the expression levels of the antioxidant genes Nrf2, HO-1 and GPX4 ( < 0.01), and enhanced the protein expressions of Nrf2 and HO-1 in the liver tissues ( < 0.01).@*CONCLUSIONS@#Exendin-4 improves liver fibrosis and oxidative stress in diabetic mice by activating Nrf2/HO-1 pathway without significantly reducing liver lipid deposition.

Objective To evaluate the efficacy of hydrocolloid dressings on preventing mechanical phlebitis induced by peripherally inserted central catheter (PICC)in cancer patients. Methods 100 cancer patients with PICC were divided into observation group (n= 50)and control group (n= 50). Hydrocolloid dressing was used in observation group and hot-wet compress was used in control group. Incidence of mechanical phlebitis,comfort degree,and im-plementation time between two groups were compared.Results The incidence of mechanical phlebitis in observation group and control group were 4.0% (2/50)and 22.0% (11/50)respectively,grade of mechanical phlebitis in obser-vation group was significantly lower than control group(P<0.05). The rates of skin irritation,activity limitation, and body exposure in observation group were all significantly lower than control group (0 vs 10 . 0% ,2 . 0% vs 14.0% ,0 vs 16.0% ,respectively,all P<0.05),the implementation time of observation group and control group were (2.8±1.1)and (35.2±7.4)minutes respectively,difference was statistically significant(P<0.05). Conclusion Hydrocolloid dressing can significantly reduce the mechanical phlebitis induced by PICC,enhance pa-tients'comfort degree,and reduce nurses'workload.
