Objective To compare the efficacy of weight loss,metformin and rosiglitazone in women with polycystic ovary syndrome(PCOS).Methods A randomized controlled trial(RCT)was carried out in Peking Union Medical College Hospital(PUMCH),one hundred and six women with PCOS were assigned to three intervention groups:weight loss,weight loss and metformin,weight loss and rosiglitazone group.Patients were treated with weight loss(diet and exercise),weight loss and mefformin (500 mg three times daily),weight loss and rosiglitazone(4 mg once daily)for three months.Sixty patients completed treatments.Basal body temperature(BBT),total testosterone as well as fasting serum insulin levels and lipid were measured and compared in all patients before and after weight loss.Results No significant differences were found in the baseline characteristics among three groups.In weight loss group 51%(22/43)patients completed treatment,and 23%(5/22)patients resumed ovulation.In weight loss and mefformin group 58%(21/36)patients completed treatment,and 43%(9/21)patients resumed ovulation.In weight loss and rosiglitazone group 63%(17/27)patients completed treatment,and 59% (10/17)patients resumed ovulation.Ovulation rate was significantly higher in weight loss and rosiglitazone group than in weight loss group.There was no significant difference among three groups in body mass index (BMI),waist circumference,waist-hip ratio(WHR),sex hormone,serum fasting insulin and lipid level after treatment.Conclusion Weight loss,metformin and rosiglitazone all can improve ovulation each.

Objective To analyse the changes of metabolic parameters and condition of metabolic syndrome(MS)in females with obstructive sleep apnea-hypopnea syndrome(OSAHS),and explore the interaction between OSAHS and MS.Methods Sixty females undergoing polysomnography were included,and were divided into simple snorer group(n=19),mild OSAHS group(n=21)and moderate to severe OSAHS group(n=20).Epworth sleepiness scale(ESS)scores and metabolic parameters were compared among groups.Forty-one patients with OSAHS were subdivided into group with MS(MS group,n=15)and group without MS(non-MS group,n=26).ESS scores,apnea hypopnea index(AHI),oxygen desaturation index(ODI)and lowest pulse oxygen saturation(LSpO_2)were compared between MS group and non-MS group.Results There was no significant difference in age,body mass index(BMI),total cholesterol(TC),triglyceride(TG),low density cholesterol(LDL),high density cholesterol(HDL),apolipoprotein A-I(apoA-I)and apolipoprotein B(apoB) among simple snorer group,mild OSAHS group and moderate to severe OSAHS group(P>0.05).Correlation analysis revealed ESS was positively related to AHI(r=0.327,P=0.011).ESS scores and proportions of hypertension,fasting plasma glucose(FPG)and MS were significantly higher in moderate to severe OSAHS group than those in simple snorer group(P<0.05).BMI,FPG,TG,proportion of hypertension,ODI and ESS score in MS group were significantly higher than those in non-MS group(P<0.05),while there was no significant difference in AHI and LspO_2 between these two groups(P>0.05). Conclusion ESS score may reflect the severity of OSAHS in females.Females with OSAHS matched for age and BMI have no difference in blood fat.With the increase of severity of OSAHS,glycometabolism can be impaired,the prevalences of hypertension and MS increase.MS can exacerbate the severity of OSAHS,indicating that MS and OSAHS interact with each other.

OBJECTIVETo investigate whether breastfeeding can reduce the risk of childhood overweight in the offspring of mothers with gestational diabetes mellitus (GDM).

METHODSFollow-up was performed on 1189 offspring of mothers with GDM between January 2003 and December 2009. The influence of the manner and duration of breastfeeding between 0 to 3 months after birth on the risk of childhood overweight in the offspring of mothers with GDM was analyzed by logistic regression.

RESULTSAfter correcting confounding factors such as pre-pregnancy BMI, gestational weight gain, gestational blood sugar, sex, birth weight, age and farther's body weight, it was found that the risk of childhood overweight in the offspring who received exclusive breastfeeding during the first 3 months after birth was lower than in the artificial feeding group (OR: 0.479, 95%CI: 0.256-0.897). Offspring who were breastfed for 0 to 3 months, 4 to 6 months and over 6 months had a lower risk of childhood overweight than the artificial feeding group (OR: 0.456, 95%CI: 0.233-0.827; OR: 0.29, 95%CI: 0.103-0.817; OR: 0.534, 95%CI: 0.280-0.970), offspring who were breastfed for 4 to 6 months had a lower risk of childhood overweight than those who were breastfed for 0 to 3 months (OR: 0.372, 95%CI: 0.129-0.874), and offspring who were breastfed for more than 6 months did not show significantly lower risk of overweight than those who were breastfed for less than 6 months (OR: 0.769, 95%CI: 0.470-1.258).

CONCLUSIONSWithin 3 months of birth, breastfeeding, especially exclusively, may reduce the risk of childhood overweight in the offspring of mothers with GDM. Within 6 months of birth, the risk of childhood overweight decreases as the duration of breastfeeding increases, but prolonging the duration of breastfeeding cannot necessarily reduce the risk of childhood overweight after postnatal six months.

Objective To investigate the exact mechanism of SARS-CoV pathogenesis at the protein level. Method Under the condition of the establishment of dendrtic cells (DC) culture method,we used recombinant adenovirus to infect mature DC to make clear the development changes in mRNA levels and secreted protein levels of proinflammatory cytokines of IL-1β,IL-6,IL-8 and TNF-α by using RT-PCR and EL1SA. Result We found that mRNA levels and secreted protein levels of IL-6 and TNF-α in DC had increased gradually after rAd-N infection during fast 24 h compared with the control DC infected by rAd-LacZ( P < 0.05 or P < 0.01 ). Conclusion It is suggested that N protein may be related to the excessive secretion of prointlammatory cytokines during SARS-CoV infection at the acute phase.

Abstract: Objective To investigate the epidemiological characteristics of pathogens causing bloodstream infection in hematology patients during treatment and to compare the effects of allogeneic hematopoietic stem cell transplantation (HSCT) on them, so as to provide evidence for the diagnosis and treatment of bloodstream infection. Methods A total of 292 cases with bloodstream infection in hematology wards of the PLA General Hospital were collected from 2017 to 2021, which were divided into HSCT group and N-HSCT group according to whether performed HSCT or not. The epidemiological characteristics and influence of pathogenic bacteria in blood stream infection were analyzed and compared between the two groups. Results A total of 362 strains of pathogenic bacteria were collected from 292 cases, including 106 strains in HSCT group (84 cases) and 256 strains in N-HSCT group (208 cases). Bloodstream infections were more common in acute myeloid leukemia (130/392, 44.52%), followed by non-Hodgkin's lymphoma (74/292, 25.34%). The rate of once bloodstream infection in HSCT group was higher than that in N-HSCT Group, but the rate of twice bloodstream infections in N-HSCT group was higher. Gram-negative Bacilli were the most common pathogens (56.08%), with Escherichia coli being absolutely dominant (109/362, 30.11%), followed by Klebsiella pneumoniae (39/362, 10.77%). Coagulase-negative staphylococci (CoNS) (107/362, 29.56%) were the most common Gram-positive cocci. The detection rate of fungi in HSCT group (10/106, 9.43%) was significantly higher than that in N-HSCT Group (3.52%). The drug resistance rate of the common pathogenic bacteria was at a high level, and there was a certain proportion of multi-drug resistant strains (except for Pseudomonas aeruginosa). The resistance rates of CoNS to penicillin, gentamicin, moxifloxacin, clindamycin and rifampicin in HSCT group were higher than those in N-HSCT Group. The resistance rate of Escherichia coli to piperacillin/tazobactam, cephalosporins and etapenem in HSCT group was significantly higher than that in N-HSCT group. Conclusions The pathogens of blood stream infection in hematology patients are complicated and various. It is difficult for clinical diagnosis and treatment to detect multiple infections and multiple pathogens. HSCT patients have a higher risk of fungal bloodstream infection and more multi-drug resistant strains detected. Therefore, the identification of bloodstream infection and multi-drug resistant strains associated with HSCT patients should prompt surveillance.

BACKGROUNDIntegrin-linked kinase (ILK) dysregulation is involved in the progression of diabetic nephropathy (DN). The aim of this study was to investigate the effects of angiotensin II receptor blocker (ARB), irbesartan, on ILK expression and podocyte injury in DN.

METHODSDN was induced by the combined feeding of high-sucrose, high-fat diet and intra-peritoneal injection of low dose of streptozotocin (35 mg/kg) in spontaneously hypertensive rats. Diabetic rats were treated with irbesartan (50 mg×kg(-1)×d(-1)) by gavage for 8 weeks. The renal morphologic changes and podocyte injury were investigated by light and electron microscopy, and the ILK expression was evaluated by real-time RT-PCR and Western blotting analysis.

RESULTSDiabetic rats exhibited with the similar clinical feature of type 2 DN. Morphologically, they were characterized by expansion of mesangial matrix, loss of podocyte and podocyte injury. Impressively, compared to controls, the ILK expression in diabetic rats were upregulated, which were positively correlated with both podocyte injury and albuminuria. Irbesartan significantly prevented ILK overexpression, along with the amelioration of podocyte injury and albuminuria.

CONCLUSIONSILK plays an important role in mediating podocyte injury in DN; irbesartan inhibits ILK upregulation and attenuates podocyte injury, which might offer a new insight into the role of ARB in preventing DN progression.
