Objective To investigate the value of interleukin-6 (IL-6) level as a prognostic indicator in diabetic ketoacidosis (DKA) patients.Methods Data of 88 cases of DKA in Sir Run Run Shaw Hospital collected from June 1,2010 to December 31,2012 were analyzed prospectively.They were divided into two groups according to the survival of patients followed up for 28 days:non-survival group (n =12) and survival group (n =76).Serum levels of IL-6,lactate,base excess and APACHE Ⅱ score in 24 hours after admission were compared between two groups by independent t test.The receiver operating characteristic (ROC) curve was plotted to analyze the performance of IL-6 as a prognostic indicator in the early stage of DKA.Correlations between IL-6 value and lactate,base excess,APACHE Ⅱ score were analyzed.Results The IL-6 values were elevated obviously in non-survival group.The ROC of IL-6 had an area under curve (AUC) of 0.783,and the cut-off value of IL-6 for the death followed up for 28 days was 448.9 ng/L.In all patients,IL-6 values and APACHE Ⅱ score showed a positive correlation between them (r =0.919,P =0.005),and also positive correlations existed between IL-6 and lactate as well as base excess (r=0.922,P=0.003; r=0.887,P=0.015)in24 hours.Conclusions IL-6 value is a reliable prognostic indicator in the early stage of DKA.

Objective To evaluate the clinical efficacy of arterial chemotherapy and partial cystotomy for treatment of bladder carcinoma. Methods A total of 171 cases of the bladder carcinoma who would undergo partial cystotomy were randomly diviede into 2 groups:(1)78 patients received arterial chemotherapy before the operation;(2) 93 cases were treated with arterial chemotherapy after the operation.In addition,35 cases who underwent operation alone were selected for the DNA content detection by FCM as control group.All these cases were followed up for 5 years. Results Among the 78 cases with the cystoscopy,the tumors disappeared in 9 cases and the tumors shrank by half or more in 49 cases.The total effective rate was 74.3%(58/78).The pathological examination showed the effective rate was 75.9%(44/58).There was a remarkable change in the carcinoma cells by the electronic microscopy.DNA index,proliferation index,SFR and aneuploid rate were detected by FCM.In the cases of grades Ⅱ and Ⅲ bladder carcinoma there was a statistically significant difference ( P

Facing the new problems under the background of new era,with the establishment of the market economy of our country and the improvment of the medical health system,how to solve medical health problems,how to strengthen the modernization management of state-owned hospital,and how to improve their comprehensive strength become the focus of the health research.With the internal and external environment analysis and the strategic management theory,this paper puts forward the development strategy and the support system of the children's hospital of Chongqing Medical University.

BACKGROUND:Current research has shown that tumor necrosis factorαstimulated gene 6 (TSG-6) has anti-inflammatory effect, and the scar formation can be inhibited by local injection of TSG-6 protein at the early stage of trauma. However, the mechanism of this effect is stil unclear. OBJECTIVE:To construct the lentiviral expression vector and shRNA vector for human TSG-6, with stable overexpression, transfection and interference, and to explore the effect of TSG-6 on proliferation and apoptosis of keloid fibroblast cel lines. METHODS:Human keloid fibroblast cel s were isolated from the keloid’s tissue by enzyme digestion and identified by immunocytochemistry assay. Lentiviral vectors pLVX-puro-TSG-6 and pLVX-shRNA1-TSG-6 were constructed and transfected into human keloid fibroblast, exclusively. Expression levels of TSG-6 mRNA and protein were detected by RT-PCR and western blot assay. MTT assay and flow cytometry were used to estimate the cel proliferation and apoptosis in each group after transfection. In addition, expression of Bcl-2, p53 and active-caspase-3 were detected by western blot assay in each group. RESULTS AND CONCLUSION:(1) Human keloid fibroblasts were separated successful y. Under the light microscope, cel s were spindle. Immunohistochemical staining for vimentin was performed in the fifth passage of cel s, with the positive rate of 100%. Cel s were negative for cytokeratin. (2) Recombinant lentiviral vectors and stably transfected cel lines were successful y established. TSG-6 gene expression was altered apparently. Compared with the control group, cel proliferation was delayed and apoptotic rate was noticeably increased in TSG-6 gene overexpression group. Cel proliferation increased and apoptotic rate decreased in the TSG-6 gene intervention group (P<0.05). (3) Western blot assay results demonstrated that Bcl-2 expression reduced, P53 and Active-caspase-3 expression significantly increased in the TSG-6 gene overexpression group (P<0.05). (4) These finding showed that TSG-6 could inhibit proliferation and induce apoptosis in keloid fibroblasts. Its mechanism may be associated with the down-regulation of Bcl-2 protein expression, up-regulation of P53 protein expression and increased Caspase-3 activity.

Objective To establish a new allele specific PCR method for GPT typing: and study GPT polymorphism by FLDAS-PCR and PCR-RFLP. Method 248 unrelated individuals of Han were genotyped using FLDAS-PCR and PCR-RFLP. Results Three genotypes were identified with DP of 0.631 in Han population. Typing results by FLDAS-PCR were completely consistent with those by PCR-RFLP. The allele frequencies were GPT * 1 = 0.5423 and GPT * 2 = 0.4577. The population data fitted the Hardy-Weinberg law. Conclusion GPT-FLDAS-PCR and GPT-RFLP method is useful for forensic identification.

0.05).(2) In the treatment group,19(70.37%) patients were cured,whose shoulder pain was relieved immediately,with the time for the complete recovery of joint function being 4.47 ? 3.08 days.In the control group,7 patients(53.85%) were cured,whose shoulder pain was relieved in 17.35 ? 6.22 days,with the time for the complete recovery of joint function being 26.13 ? 3.58 days.The differences between the two groups were significant(P

Objective To observe the effect of tumor necrosis factorαstimulated gene-6 ( TSG-6 ) on hypertrophic scarring by using a rabbit ear model. Methods TSG-6 and PBS were injected intradermally in the right and left ear wounds, respectively. Collagen I and III expression detected by immunohistochemistry and scar elevation index ( SEI) was used to evaluate the extent of scarring. The expression of inflammatory factors interleukin-1β( IL-1β) , interleukin-6 ( IL-6 ) and tumor necrosis factor-α( TNF-α) was detected by immunohistochemistry and reverse tran-scription polymerase chain reaction. Transmission electron microscope ( TEM) and TUNEL analyses were used to detect fibroblast apoptosis. Results Compared with control scars, TSG-6-treated wounds exhibited decreased in-flammation significantly as evidenced by the lower levels of IL-1β, IL-6 , TNF-α. The apoptosis rate was higher and the SEI and the synthesis of collagens I and III were significantly decreased in the TSG-6-treated scars ( P<0. 05 ) . Conclusion Immediate topical injection of TSG-6 during the wound healing process can reduce the severity of hy-pertrophic scarring in a rabbit model. The anti-cicatrix effect of TSG-6 may result from controlling inflammation, in-ducing fibroblast apoptosis and promoting collagen degradation.

0.05).Conclusions The serum MMP-9 can be tested as an objective index in appraisal the severity of the left to right shunt.The increased level of MMP-9 may be one of important mechanism for developing heart failure process in children with left to right shunt CHD.Monitor the level of MMP-9 will help us find adverse myocardial remodeling earlier and begin treatment immediately to prevent heart failure developing.
