Objective To evaluate the association of the 5'-end dinucleotide repeat polymorphisms of the aldose reductase gene and susceptibility to diabetic nephropathy in Chinese patients with type 2 diabetes mellitus by means of meta analysis. Methods Genetic association studies evaluating the 5'-end dinucleotide repeat polymorphism of the aldose reductase gene and susceptibility to diabetic nephropathy in type 2 diabetes mellitus patients involving Chinese population published before April 2007 were collected from database of PubMed, EMBASE, and CNKI. All the literatures were abstracted based on the defined selection criteria by two independent investigators. Publication bias was tested by funnel plot and the odd ratios of all studies were combined depending on the result of heterogeneity test among the individual studies. The software Review Manager (version 4.2) was used for meta analysis. Results Eight studies involving 5'-end dinucleotide repeat polymorphism of the aldose reductase gene and susceptibility of diabetic nephropathy in Chinese patients with type 2 diabetes mellitus met the selection criteria. There was no significant publication bias in selected studies. Heterogeneity test showed that there were significant statistic differences among the individual studies about the frequencies of Z-2 (χ2=18.20, P= 0.01) and Z + 2 (χ2 = 35.30, P < 0.01) allele in different groups. The combined OR of susceptibility to diabetic nephropathy in patients with Z-2 allele was 1.72 (95% CI 1.25-2.36, P < 0.01) and those of Z + 2 and Z + 6 were 0.73 (95% CI 0.47-1.12, P =0.15) and 0.66 (95%C10.45-0.98, P = 0.04) respectively. Conclusion The 5'-end dinucleotide repeat polymorphism of the aldose reductase gene was associated with the susceptibility of diabetic nephropathy in Chinese patients with type 2 diabetes mellitus. The Z -2 allele is a genetic risk factor for diabetic nephropathy, while the Z + 6 allele has protective function for kidney mierovessels.

OBJECTIVE To study and evaluate the value of the antibiotic-neutralized culture bottle applied by manual operations.METHODS A total of 711 blood samples were collected from clinical high fever patients in Qingdao Central Hospital from 2002 to 2005.To compare the bacteria detected rates,cultural time and bacteria types in 399 samples cultured in manual blood-culture bottles with those in 312 samples cultured in antibiotic-neutralized culture bottles applied by manual operations.RESULTS The bacteria detected rates were 10.28% in manual blood-culture bottles and 20.83% in antibiotic-neutralized culture bottles applied by manual operations.There was significant difference between both of them(P72h were no statistical difference between manual blood-culture bottles and antibiotic-neutralized culture bottles.Twenty species of bacteria were detected in manual blood-culture bottles and 29 species of bacteria in antibiotic-neutralized culture bottles applied by manual operations.CONCLUSIONS The bacteria detected rate and species of bacteria were more obviously raised in antibiotic-neutralized culture bottles applied by manual operations than in manual blood-culture bottles.

Objective To explore more suitable calculation method of the insulin dosage in insulin hypoglycemia-growth hormone stimulation test(insulin tolerance test, ITT). Methods Fifty-six subjects suspected of growth hormone deficiency were divided into primary and secondary onset groups. All the patients took oral glucose tolerance test and ITT. Homeostasis model of assessment for insulin resistance index ( HOMA-IR) and insulin sensitivity index ( ISI), area under insulin curve ( AUCINS ) and the area under glucose curve ( AUCPG ) were calculated. The insulin dosages during ITT between two groups were compared and the main factors influencing the insulin dosage were analyzed. Results There was no difference in the insulin dosage during ITT between primary and secondary groups. The actual dosage of insulin in this cohort study revealed a significant difference from the initial insulin dosage recommended by the guideline. Multiple linear regression analysis found that AUCINS and body mass index were the independent factors affecting the insulin dosage. Then the optimized coefficient of ITT ( γ) were found. Conclusion The insulin dosage used in our study was inconsistent with the guidelines-recommended ones. In order to make ITT more efficient and safer, a more optimized calculation method to improve the successful rate of insulin-induced hypoglycemia in ITT is proposed.

Objective To study the clinical features and follow-up of newborns with severe hypoxic-ischemic encephalopathy ( HIE) , and to provide the basis for rational diagnosis, treatment and follow-up.Methods Clinical data of cases of HIE from the Neonatal Department of our Hospital from January 2011 to October 2014 were studied retrospectively. The data of general information, laboratory examination, treatment, outcome, follow-up and prognosis of the patients were collected. Multivariate logistic regression analysis was used to study the influential factors of the prognosis of HIE.Results A total of 123 infants with sever HIE were enrolled in our study. In addition to general therapy, 6 cases were treated with mild hypothermia, and 21 cases were treated with high pressure oxygen. 60 cases improved our treatment, 55 cases had withdrawal treatment with parental consent, and 8 cases died. Single factor analysis showed that 5 minutes Apgar score, convulsions, coma, pH, BE, organ injury, and mild hypothermia treatment were the risk factors that affect the prognosis of severe HIE. Multiple factors analysis showed that 5 min Apgar score <3 points ( OR=4. 071 ,95℅CI 1. 309-15. 613 ) and BE≤-10 mmol/L ( OR=36. 810, 95℅CI 5. 913-41. 119) were independent risk factors of prognosis of severe HIE ( P<0. 05). Hospitalization within the first 72 hours of life ( OR=0. 096, 95℅CI 0. 096-0. 353) was a protective factor of severe HIE. Multiorgan injury ( mainly the injury of brain, lung and heart) and electrolyte imbalance ( mainly hypocalcemia and hyponatremia ) were common complications of serve HIE. In the follow-up of these patients, 33 cases were loss in follow up, and 49 cases died (8 cases died during hospitalization, 41 cases died after withdrawal of treatment). The top five causes of death were abandonment of treatment due to financial reasons and the fear of adverse outcome (n=20), multiple organ dysfunction ( n =16 ) , and pneumothorax ( n =4 ) , diffuse intravascular coagulation (n=6), and shock (n=3). 41 cases survived were followed up for 9~54 months. The critical clinical conditions observed among these infants included cerebral palsy ( n = 5 ) , epilepsy ( n = 3 ) and developmental retardation(n=26).Conclusions There are many complications of severe HIE.The mortality of severe HIE is high, and the incidence of poor outcome of survivors is also high. Timely detection of risk factors is the key to the prevention of severe HIE. Long-term prognosis of severe HIE requires proper organization of neonatal follow up.

Objective To study the prevalence of metabolic syndrome (MS) in women with polycystic ovary syndrome (PCOS) ,and to explore the risk factors of MS in young women. Methods The prevalence of MS and its components were evaluated in 348 young women with PCOS and 113 control subjects without PCOS. Results According to the 2005 modified Adult Treatment Panel Ⅲ criteria,MS was found in 27.0% of PCOS women,being significantly higher than 10.6% in the controls(P<0.01). The rates of MS components,except for the triglyceride (TG) level, were all significantly higher in PCOS subjects than those in control subjects ( P < 0. 05 or P < 0.01). However, the difference disappeared after adjustment for age and body mass index ( BMI, P>0. 05). The results of logistic regression analysis revealed that homeostasis model assessment insulin resistance (HOMA-IR)and BMI were the independent predictors of MS( both P<0.01) ,and the presence of PCOS was not the independent risk factor for MS (P>0. 05). Conclusions Obesity and insulin resistance are the independent predictors of MS. PCOS alone does not increase the risk of MS prevalence.

ObjectiveTo compare the sensitivity and specificity of a new index of insulin resistance (IR) derived from plasma triglyceride and glucose with homeostasis model assessment for insulin resistance index ( HOMA-IR) and insulin sensitivity index from frequent sampling intravenous glucose tolerance test (FSIGT-ISI).Methods A total of 1024 subjects (240 normal control,335 with obesity,312 impaired glucose regulation,and 137 type 2 diabetes mellitus) were included in the present study.Standard oral glucose tolerance test,insulin release test,lipid profiles,and other biochemical markers were measured. Among them 540 subjects were selected to undertake FSIGT.TyG index is derived from plasma triglyceride and fasting glucose.TyG2 index is derived from plasma triglyceride and postprandial 2 plasma glucose.ResultsPearson correlation coefficient between TyG and HOMA-IR or FSIGT-ISI was 0.427 ( P＜0.01 ) and -0.100 ( P=0.024 ),respectively,and that between TyG2 and HOMA-IR or FSIGT-ISI was 0.455 ( P＜0.01 ) and - 0.162 ( P＜0.01 ),respectively.The sensitivity and specificity of TyG index for diagnosis of IR was 68.5％ and 63.5％ compared with HOMA-IR,and 68.5％ and49.5％ compared with FSIGT-ISI.For TyG2 index,the slightly higher sensitivity ( 81.7％ with HOMA-IR,75.7％ with FSIGT-ISI),but lower specificity (51.5％ with HOMA-IR,48.2％ with FSIGT-ISI) were found.ConclusionsBothTyGandTyG2 indices could be used as a surrogate for assessing IR in Chinese subjects.However,considering its moderately high sensitivity but low specificity,these two indices are limited in the use of large-scale epidemiological screening.

BACKGROUND: Adipose-derived stem cells have the advantages of easy access, easy separation, small trauma, and rapid proliferation. Current treatments for kidney injury are more limited, and adipose-derived stem cells may provide a new treatment route. OBJECTIVE: To investigate the effects of adipose-derived stem cell transplantation on the kidney function of rats with acute kidney injury induced by crush injury in rats. METHODS: Cryopreserved adipose-derived stem cells were recovered in vitro and cultured to prepare cell suspension following labeling with PKH-26. Twenty rats were randomly selected from 66 experimental Sprague-Dawley rats (provided by Beijing Vital River Laboratory Animal Technology Co., Ltd.) as normal control group. In the 40 of the remaining 46 rats, a pathological model of acute kidney injury caused by compression injury was successfully established by the use of forceps to double the proximal hind limbs. The 40 rat models were divided into model group and cell transplantation group, with 20 rats in each group. After 6 hours of modeling, the rats in the model group were given intravenous injection of normal saline (20 μL) , and the rats in the cell group were given intravenous injection of PKH-26-labeled adipose-derived stem cells (20 μL, 3×106/L) , once a day for 3 continuous days. The levels of serum creatinine and urea nitrogen were measured in each group at 1, 3, 14 and 21 days after transplantation. The left kidney of the rats in each group was observed using hematoxylin-eosin staining, TUNEL staining, RT-PCR and western blot assay at 3 and 21 days after cell transplantation. RESULTS AND CONCLUSION: (1) The levels of creatinine and urea nitrogen in the serum of rats at 1, 3, 14 and 21 days after cell transplantation were significantly higher in the model group than the normal control group (P < 0.05) and cell transplantation group (P < 0.05). (2) At 3 and 21 days after cell transplantation, the scores on the kidney injury and apoptotic rate of kidney cells were ranked as follows: model group> cell transplantation group> normal control group, and there were significant differences between groups (P < 0.05). (3) At 3 and 21 days after cell transplantation, the expressions of bax and Caspase-3 in the kidney tissue at mRNA and protein levels were significantly higher in the model group and cell transplantation than the normal control group (P < 0.01) as well as significantly higher in the cell transplantation group than the model group (P < 0.05). To conclude, adipose-derived stem cell transplantation has obvious repairing effect on acute kidney injury caused by crush injury, and its mechanism may be related to the involvement of adipose-derived stem cells in regulating the expression of bax and Caspase-3.

OBJECTIVETo determine the ginsenoside Rg2 and study its excretion in bile, feces and urine of rat.

METHODReversed phase high-performance liquid chromatographic (RP-HPLC) method with an ultra-violet detector (UVD) was performed at a detection wavelength of 203 nm and with a Dikma Diamonsil C18 column (4.6 mm x 250 mm, 5 microm), which the mobile phase was consisted of methanol-aq. 4% H3PO4 (65:35), for determination of the ginsenoside Rg2 in bile, feces and urine after administration of the ginsenoside Rg2 to rat at a tail vein single dose of 20 mg x kg(-1).

RESULTThe HPLC-UVD method fulfilled all the standard requirements of linearity, recovery, precision, and accuracy. After tail vein administration of the ginsenoside Rg2 to rat, the 5.5 hour cumulative biliary excretion rate and the 24-hour cumulative feces excretion rate of intact ginsenoside Rg2 were 27.2% and 22.6% of the administered dose, respectively. But intact ginsenoside Rg2 could not be detected in urine during this experimental period.

CONCLUSIONThe bile and feces were the main excretion routs of the unchanged form after tail vein administration of the ginsenoside Rg2 to rat.
