ObjectiveTo study the effect of 1,25-(OH)2D3 analogs paricalcitol on proteinuriaindiabeticnephropathy (DN)rats, andtoinvestigateitspossiblemechanism.Methods DN model rats were established by intraperitoneal injection with streptozotocin.All the DN rats were randomly divided into the paricalcitol group(group P ) and DN group(group D).Healthy rats were chosen as healthy control group(group N).24-h urinary protein and serum biochemical indicators were examined after 12 weeks.ELISA was applied to detect the level of renin and Ang Ⅱ in the kidney.Immunohistochemistry and real-time PCR were used to detect the protein and mRNA expression of heparanases(HPA)and podoein.Results Compared with group N,24-h urinary protein,serum creatinine,renin and Ang Ⅱ in group D and group P were markedly increased,and they were significantly higher in group D as compared to group P (all P＜0.05).Compared with group N,the expression of HPA protein and mRNA in group D and group P increased markedly,and higher expression was found in group D(all P＜0.05).The expression of podocin protein and mRNA in group D and group P decreased markedly,and lower expression was found in group D(all P＜0.05).Renin level was positively correlated with HPA protein expression (r=0.78,P＜O.OS),negatively correlated with podocin protein expression(r=-0.63,P＜O.05),and not correlated with their mRNA expression.Conclusion Paricalcitol can significantly reduce the proteinuria,which may be associated with the inhibition of renin by down-regulating protein expression of HPAin glomerular basement membrane and up-regulating protein expression of podocin in podocyte.

Objective To explore the effect of treatment of children's stress hyperglycemia with glucose-insulin-potassium.Methods Thirty children with stress hyperglycemia were randomly divided into two groups,15 cases in each group.Patients in the treated group were admi-nistered with glucose-insulin-potassium,whereas those in the control group,glucose were transfused at the speed

The biotechnology of glycolipid fermented b y a bacillus coagulans was studied and the fermentation pro cess in 10L bioreactor was conducted.Suitable medium contained 6% bean oil as ca rbon source,3 5g/L NaNO 3 as nitrogen source,0 75g/L yeast extract and some i no rganic salts.The fermentation temperature of 30℃,initial pH of 8 5,strring rev olution of 150～240r/min and fermentation period of 96h proved to be optimal.The yield of glycolipid in 10L bioreactor was 7 073g/L.

This article reviews recent advances in apoptosis on the pathway inducing cancer cell to death, including Bcl-2 family pathway, NF-kappa B pathway, P13K/Akt pathway, Rb gene and p53 gene, especially the targets of anticancer drug in these pathways. It could be useful for the anticancer drug design and estimate. Furthermore, those cancer/testis antigen gene products are potential targets for antigen-specific immunotherapy of carcinoma.

OBJECTIVETo study the prevalence and associated factors of suicide attempt in middle school students.

METHODSFive middle schools in Chengdu were randomly sampled in the study. A total of 1393 students between the ages of 11 and 18 finished a self-administered questionnaire, Beck Depression Inventory (BDI), Adolescent Self-Rating Life Events Check List (ASLEC) and Egma Minnen av Bardodosnauppforstran (EMBU). Everyone who had suicide attempts was interviewed. Data were analysed by SPSS 8.0 (statistical package for the social science) program on computer.

RESULTSThirty-six (2.6%) of the 1 393 students has the history of attempted suicide and the ratio of boys and girls was 1:2. Among the suicide attempters, 33.3% had recurrent events. The most common reason of suicide attempts in middle school stage was family conflicts (34.4%) with most common event as taking overdose tranquilizers or poisoning (50.0%). Risk factors of suicide attempt seemed to include hallucination, cigarette smoking, being bullied by peers, wanting to change sex, parents' remarriage, being female, father's refusal, being neglected in childhood and experiencing more events in the previous year. Protecting factor was found to have been family warmness.

CONCLUSIONSuicide attempts were not uncommonly seen in middle school students. Clinicians and teaching staff should identify the risk factors and carry out intervention as early as possible.

Objective To explore the relating factors for cognitive dysfunction in patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD).Methods Totally 150 patients with acute exacerbation of COPD (AECOPD) and 150 gender and age-matched healthy subjects (controls) received the cognitive and depression function assessment.150 AECOPD cases were classified into two groups:COPD patients with or without cognitive dysfunction.Fasting blood uric acid (UA) was measured and compared between the two groups.Relating factors for cognition dysfunction were analyzed.Results The score of Montreal Cognitive Assessment (MoCA) was reduced in AECOPD patients as compared with controls [(19.01±3.58) vs.(26.58±1.42)scores,t=-3.48,P=0.032].The score of Hamilton depression (HAMD) scale was higher in AECOPD patients than in controls [(18.05 ± 4.50) vs.(9.98 ± 3.51) scores,t =4.63,P =0.028].The prevalence of cognitive impairment in the patients with AECOPD was 82 cases (54.7％).The serum UA level was lower in the AECOPD patients with cognitive impairment than in patients without cognitive impairment [(235±42) μmol/L (n=82) vs.(332±45) μmol/L (n=68),t=-6.65,P=0.003].In AECOPD patients,the cognitive function was correlated with education,length of hospital stay,serum UA level,COPD stages,disease duration and the depression level,but was not correlated with smoking and body mass index.Conclusions The cognitive impairment is highly prevalent in patients with AECOPD,which is associated with lower serum UA level,longer hospital stay and disease severity.

Objective To explore the effect of Melatonin(MT) on CD4+CD25+ regulatory T cell (CD4+CD25+Tr)and airway inflammation in asthmatic rat.Methods Thirty-two SD rats were randomly divided into 4 groups,8 rats in each group.Asthmatic group:rats were immunized on day 1 and 7 by intraperitoneal inject of mixture of ovalbumin(OVA) and aluminumhydroxide.From day 14,the animals were allenged with aerosolized OVA for 20 min per day for 7 consecutive days.MT group:OVA-sensitized rats were injected intraperitoneally with 0.1 mg/kg MT 30 min before each OVA challenge.Dexamethasone group:OVA-sensitized rats were injected intraperitoneally with 0.5 mg/kg Dexamethasone 30 min before each OVA challenge.Control group:OVA for inhalation and MT for intraperitoneal injection was replaced with saline.After the last challenge,peripheral blood was stained to count the percentage of eosinophil(EOS).Then the rats were lavaged and total leukocytes counts in bronchoalveolar lavage fluid(BALF) were performed after staining with Wright-Giemsa staining.The EOS counts around the airway was counted after the histological section of lung staining with hematoxylin and eosin staining.The serum level of immunoglobulin E(IgE) was detected by immunoenhancement.The change of CD4+CD25+Tr was assessed with flow cytometry.SPSS 10.0 software was applied to analyze data. Results In asthmatic rats,the CD4+CD25+ Tr/ CD4+T cells ratio had significant negative relationship with the EOS counts around the airway and the total leukocytes counts in BALF (r=-0.73 P0.05).There was a significant decrease in the percentage of the eosinophils in peripheral blood,the eosinophil counts around the airway,the total leukocytes counts in BALF and the serum level of IgE in MT group compared with asthmatic group (Pa

Objective:To observe the changes in the anatomy of anterior segment before and after phacoemulsification for treatment of angle-closure glaucoma by Pentacam system,so as to assess the efficacy of phacoemulsification combined with artificial lens implantation(ALI)in treatment of early-and middle-stage angle-closure glaucoma.Methods:Forty-two patients with early-and middle-stage angle-closure glaucoma(44 eyes)were included in the present study.The central anterior chamber depth,anterior chamber volume and peripheral anterior chamber angle were examined by Pentacam system pre-operatively and 1 day,1 week and 3 months post operatively.Meanwhile,A ultrasound was used to examine the anterior chamber depth before and 3 months after operation.and the results were compared with those by Pentacam system.Results:Pentacam system could clearly demonstrate the 3-dimensional structures of the anterior eye segment before and after operation.The central anterior chamber depth,anterior chamber volume and anterior chamber angle were increased significantly after operation(P
