Objective To study the safe drinking duration of purified drinking water of water dispensers, the relationship between the sanitary quality of purified drinking water and the structure of the water dispensers. Methods 30 drinking water dispensers were collected from the market and divided into 3 groups based on the structural types. A following-up experimental observation for the changes of the microbiological indexes of the water samples from the taps of water dispensers with different structures during the different prolongating operating period was carried out. Results The safe drinking duration was ≤ 4 days for the purified drinking water sampled from the taps of the water dispensers with common type at the normal atmospheric temperature and ≤ 14 day for water dispensers with bacterial inhibition type. The sanitary quality of the purified drinking water sampled from the taps of water dispensers was associated with the structural type of water dispensers, but not the brands of water dispensers. Conclusion The experimental results of the water samples collected from the taps of water dispensers with bacterial inbibition type at normal atmospheric temperature was better in quality than those of common type. The water dispensers with bacterial inhibition type provided with hygienic licence should be better recommended to choice.

Sepsis-induced cardiomyopathy(SICM)is a reversible cardiac insufficiency in the early stage of sepsis, and mainly manifests as left ventricular dilation, decreased ejection fraction, and recovery within 7~10 days.Although it is reversible, the incidence and mortality in sepsis are high.The specific mechanism is still unclear.Inflammatory reaction, mitochondrial dysfunction, apoptosis and other pathophysiological processes play an important role.Its process is complex and involves the interaction between organism and pathogen.The management of SICM is still based on the etiologic treatment of septic shock guided by hemodynamic monitoring and tissue perfusion, with cardio-protective therapy and specific measures.This review summarizes the literatures on the mechanisms and treatments of SICM.

To investigate the relationships among plasma secreted frizzled-related protein ( sfrp) 5 level and body fat parameters, glucolipid metabolism, insulin resistance index, and inflammation. 89 subjects with normal glucose tolerance(NGT) and 87 patients with type 2 diabetes mellitus (T2DM) were enrolled and each group was divided into no-obese and obese subgroups. Obesity was defined as body mass index ( BMI)≥25 kg/m2 according to the World Health Organization -Western Pacific Region diagnostic criteria ( 2000 ) . Body fat parameters were measured and BMI, waist-hip ratio were evaluated, meanwhile, the levels of blood glucose-lipid parameters and fasting insulin were also determined. Insulin resistance index ( IR) was assessed by homeostasis model assessment ( HOMA) . The concentrations of plasma sfrp5 and interleukin 6 were detected by enzyme-linked immunosorbent assay. Plasma sfrp5 level in T2DM group was significantly lower than that in NGT group [(8. 35±3. 38 vs 11. 35±3. 69)ng/ml, P<0. 01]. The levels of plasma sfrp5 in subjects with obesity were also lower than those in subjects with no-obesity in both NGT and T2DM groups [(9. 46±2. 70 vs 13. 12±3. 62)ng/ml and(6. 70±2. 34 vs 10. 12±3. 45) ng/ml, both P<0. 01]. Plasma concentrations of sfrp5 in T2DM-obese group were significantly lower than that in NGT-obese group(P<0. 01). Correlation analysis showed that plasma sfrp5 levels were negatively correlated with waist-hip ratio, HbA1C, fasting insulin, triglycerides, waist circumference, fasting plasma glucose, interleukin 6, natural logarithm of HOMA-IR [ln(HOMA-IR)], and BMI(P<0. 01 or P<0. 05). Multiple linear regression showed that ln(HOMA-IR), BMI, triglycerides were independent related factors in influencing the levels of plasma sfrp5 (r2=0. 216, 0. 177, 0. 113, all P<0. 05). Plasma sfrp5 levels were decreased in obesity and T2DM subjects and were correlated with body fat disposition, glucose-lipid metabolism, insulin resistance and inflammation. Lack of sfrp5 may contribute to the pathophysiology of obesity and T2DM.

Objective To detect plasma progranulin (PGRN) level in subjects with newly diagnosed type 2 diabetes mellitus and to investigate the relationship of plasma PGRN level with glycolipid metabolism,inflammation,and insulin resistance.Methods Eighty patients with newly diagnosed type 2 diabetes (T2DM) and 88 subjects with normal glucose tolerance (NGT) were recruited in the study.Both of them were divided into normal weight (NW)subgroup and obesity (OB) subgroup.Obesity was defined as body mass index (BMI) ≥ 25 kg/m2 according to the World Health Organization-Western Pacific Region diagnostic criteria(2000).Body fat parameters were measured and BMI,waist-to-hip ratio were determined.Fasting plasma PGRN and interleukin-6 (IL-6) levels were determined by ELISA,fasting plasma glucose (FPG),2 h plasma glucose after glucose loading (2hPG),HbA1C,fasting insulin (FINS),and lipids were also detected.Insulin resistance and pancreas β cell function were assessed by homeostasis model assessment (HOMA-IR,HOMA-β).Results Plasma PGRN level was significantly higher in T2DM group than that in NGT group(P＜0.01).Within groups of T2DM and NGT,plasma PGRN level in OB subgroups was higher than that in NW subgroups [(225.22 ± 34.39 vs 195.59 ± 50.47 and 183.79 ± 61.63 vs 148.69 ± 55.27) ng/ml,P＜0.05].Bivariate correlation analysis showed that plasma PGRN level was positively correlated with weight,waist circumference,BMI,systolic blood pressure,FPG,2hPG,HbA1C,triglyceride(TG),IL-6,FINS,and HOMA-IR (P＜0.05 or P＜0.01),and was negatively correlated with HOMA-β (P＜0.05).Multiple linear regression analysis showed that BMI,HbA1C,IL-6,and TG were independently related to plasma PGRN level(P＜0.05).Conclusions Plasma PGRN level was increased in patients with type 2 diabetes as well as in obesity,and was closely related with glycolipid metabolism,inflammation,and insulin resistance.

Objective: We observed the influence of recombinant human growth hormone(rhGH) on protein metabolism in hepatocirrhotic rats and investigated mechanisms. Methods: Ninety rats were randomized into three groups(n=30 for each group): group A(normal rats), B(cirrhotic rats) and C(cirrhotic rats receiving rhGH). Rats in group C were subcutaneously given rhGH with a dosage of 1 U/(kg?d) for up to 1 week. The plasma concentrations of albumin(ALB), prealbumin(PA), transferrin(TF) and insulin-like growth factor-1(IGF-1) were detected on experimental day 14. And liver biopsy was taken to examine the expression level of albumin mRNA with TR-PCR. Results: The albumin, prealbumin, transferrin and IGF-1 levels in groups A and C were significantly higher than those in group B. The expression level of albumin mRNA in grup C was significantly higher than that in group B. Conclusions: The rhGH can improve the level of IGF-1 in plasma and improve the expression of albumin mRNA. Moreover, it may significantly improve the synthesis of protein and attenuate hypoproteinemia in cirrhotic rats.

Objective: We analyzed the clinical data of 89 septic shock in children retrospectively to provide evidence of early diagnosis, treatments and improving prognosis for children who had septic shock and acute kidney injury(AKI). Methods: Eighty-nine children were selected from June 2013 to December 2018 in the PICU of Children′s Hospital Affiliated to the Capital Institute of Pediatrics.According to whether accompanied by AKI or not, they were divided into two groups: 56 cases of patients with septic shock accompanied by AKI in the research group, and 33 cases of patients without AKI in the control group.Then we used SPSS25.0 software to analyze the clinical data with univariate and multivariate analysis. Results: The mortality of research group and control group were 46.4%(26/56) and 39.4% (13/33), respectively.There were obvious differences between two groups in pediatric critical illness score(PCIS), the number of organ failure, nervous failure, hepatic failure, circulatory failure, lactic acid, γ-glutamyltransferase, creatinine, urea, total bilirubin, direct bilirubin(P<0.05). Logistic regression showed that hepatic failure(OR 0.099, 95%CI 0.018~0.549), PCIS<80(OR 0.223, 95%CI 0.064~0.774), lactic acid>4.1 mmol/L(OR 0.221, 95%CI 0.055~0.885) were independent risk factors for septic shock with AKI. Conclusion The mortality of septic shock with AKI is high.Hepatic failure, PCIS<80, lactic acid>4.1 mmol/L are independent risk factors.Septic shock is a systemic inflammation which can influence all organs.In order to reduce the incidence of AKI, it′s necessary to pay early attention to the changes of microcirculation such as lactic acid.

Objective:Health education program based on information-motivation-behavioral skills model (IMB model) was developed, and its application effect in functional exercise after autogenous arteriovenous fistula (AVF) in hemodialysis patients was explored.Methods:Using the convenient sampling method, 100 patients undergoing AVF surgery in hemodialysis center of Qingdao Municipal Hospital from June 2020 to June 2021 were selected as the study objects. The patients were numbered according to the order of visit. The single number was the observation group, and the double number was the control group. There were 50 patients in each group. The control group was given routine AVF function exercise education, and the observation group was given AVF function exercise education based on the IMB model. Patients′ compliance with functional exercise, cephalic vein diameter, fistula maturation time, and the incidence of complications were compared between the two groups.Results:Finally, 49 cases in the control group and 50 cases in the observation group finished the research. The compliance of function exercise of the observation group was 94.0%(47/50), which was higher than 73.5%(36/49) in the control group, and the difference was statistically significant ( χ2=7.70, P<0.05). The maturation time of plasty in the observation group was (5.18 ± 1.14) weeks, shorter than that in the control group (5.94 ± 1.39) weeks, and the difference was statistically significant ( t=2.98, P<0.05). The cephalic vein diameter and blood flow controlled by hemodialysis pump in the observation group were (5.19 ± 0.28) mm and (218.40 ± 24.19) ml/min, respectively, higher than those in the control group (4.99 ± 0.34) mm and (200.41 ± 23.89) ml/min, the differences were statistically significant ( t=-3.21, -3.72, both P<0.05). The incidence of fistula complications in the observation group was 6.0%(3/50), lower than 22.4%(11/49) in the control group, and the difference was statistically significant ( χ2=5.52, P<0.05). Conclusions:The application of IMB model in hemodialysis patients with functional exercise after AVF plasty can effectively improve patients′ compliance, increase the diameter of cephalic vein and the blood flow controlled by dialysis pump, shorten the maturation time of internal fistula, and reduce the incidence of complications of AVF.
