BACKGROUND:To control blood glucose, blood pressure, blood lipids and inhibit the rennin-angiotensin system is the main idea focused on the treatment of diabetic nephropathy, but the curative effect is unsatisfactory. Hemodialysis and kidney transplantation are suitable for serious cases, however, which is restricted because of the limited source of kidneys and high cost. Regenerative medicine research based on stem cells brings a new hope for treatment of diabetic nephropathy. OBJECTIVE:To comprehensively analyze the mechanism underlying different sources of stem cells for treatment of diabetic nephropathy and the clinical implications. METHODS:Papers addressing stem cells for the treatment of diabetic nephropathy were retrieved by computer in CNKI database and PubMed database from January 2005 to August 2013 with the key words“embryonic stem cells, bone marrow mesenchymal stem cells, induced pluripotent stem cells, diabetic nephropathyin Chinese and English. Papers published recently or in journals with high impact factor were selected. A total of 60 papers were included for review. RESULTS AND CONCLUSION:Embryonic stem cells, bone marrow mesenchymal stem cells, induced pluripotent stem cells have the potential to differentiate into renal histiocytes. A large numbers of experimental studies have shown that stem cells transplantation has a positive effect on recovery of injured kidney. Stem celltransplantation can provide a novel therapy for diabetic nephropathy.

Objective: To assess the diagnosis value of applying integrated visual and auditory continuous performance task(IVA-CPT) and EEG biofeedback on children with attention-deficit- hyperactivity disorder(ADHD), and provide information for assisting diagnosis of ADHD. Methods: 113 children with ADHD were tested with IVA-CPT and EEG biofeedback. The sensitivity, specificity, misdiagnosis rate and missed diagnosis rate of these two methods were assessed according to the criteria of DSM-Ⅳ. Results: The sensitivity of IVA-CPT for the diagnosis of children with ADHD was 92.54, the specificity was 76.09%, misdiagnosis rate was 23.911% and missed diagnosis rate was 7.46%. And the sensitivity of EEG biofeedback for the diagnosis of children with ADHD was 83.58%, the specificity was 82.61%, misdiagnosis rate was 17.38 and missed diagnosis rate was 16.42%. Conclusion: Relatively, for diagnosis of children with ADHD, sensitivity is higher and missed diagnosis rate is lower, specificity of EEG biofeedback is higher and misdiagnosis rate is lower .

Objective To investigate wheter epigallocatechin gallate (EGCG) could prevent the information of abrant crypt loci (ACF) induced by isoquinoline (IQ)and its possible mechanisms. Methods Sixty male BALB/cA nude immunological deficit mice were divided into five groups. Except control group, the other four groups were received IQ to induce ACF. The rats in low, medium and high dose groups were received 5, 10 and 20 mg/kg of EGCG,respectively. The mice were sacrificed six weeks later. Hematoxylin-eosin (HE) staining and 0.2% methylene blue staining were used to observe the routine histology and ACF, respectively. Immunohistochemistry (IHC) was used to detect Nrf2 protein level and RT-PCR was used to detect Nrf2 and UGT1A10 mRNA levels in colon tissue. Results The body weights of model group decreased significantly compared to high-dose group (21.70±0.13 vs. 24.37±0.07, P<0.01). Compared to model group, the degree of atypical hyperplasia and even canceration of colon mucus and the number of total ACF and total AC in high-dose group were decreased significantly (18.00±7.51 vs. 64.20±45.18, P<0.05;63.90±18.58 vs. 168. 80±35.34, P<0.01). The protein level of Nrf2 increased (0.3114±0.0037 vs. 0.1660±0.0021, P<0.01). The mRNA levels of Nrf2 and UGT1A10 in high-dose group was increased (both P value<0.01). Conclusions EGCG has protective effect on IQ induced preneoplastic lesions through reducing the number of ACF. This effect may be caused partly through the signal pathway Nrf2-UGT1A10.

Objective To observe the clinical effects of the children with svstemic inflammatorv re- active syndrome(SIRS)receiving micro-dose heparin at early stage of the diseases.Methods The 53 cas- es diagnosed as SIRS were included in the randomized control trial.They were divided into two groups,26 cases in control group and 27 cases in therapeutic group.The children in control group received therapy for their primary diseases and other routine managements for SIRS.The children in therapeutic group received both above therapy and micro-dose heparin(5-10 U/kg,1 fime/6hours)via subcutaneous injection at earlv stages of diseases for 3 days.Results There were improvements in both control and therapeutic group, platelets count increased,C-reactive protein decreased (P＜0.01),there were significant diffemnce in platelets and C-reactive protein between two groups,the time of platelets recovery in therapeutic group [(28±9)h]Was less than that in control group[(55±14)h](P＜0.01).In therapeutic group,the dumtion of SIRS was shortened (P＜0.05),mortality and the incidence of multiple organ dysfunction svndrome (MODS)and disseminated intravascular eoagultion(DIC)were decreased significantly(P＜0.05).Con- clusion Early micro-dose heparin in SIRS can shorten its duration and decrease the mortality and the inci- dence of MODS in the children with SIRS.

Objective: To study the general characteristics of autistic children. Methods: The data of 1176 autistic children who were diagnosed in the Institute of Mental Health, Beijing Medical University was gathered, descriptive statistics were done with SPSS software. Results: As many as 35.10% of the autistic children are identified by their parents having problems in behavior until they were 3 years old. The average age of consulting was 60.61?26.8 months. Only 21.43% children were brought to child psychiatrists under the age of 3. They were brought to hospital 35.03?27.86 months after being discovered the symptoms.Conclusion:Health education for child autism should be strengthened so that it can be early identified.

Purpose To investigate the clinical and pathological features of inflammatory fibroid polyps ( IFPs) and to discuss its diag-nosis, differential diagnosis and treatment. Methods Clinicopathological data of 14 cases of IFPs were collected and analyzed retro-spectively. Results Most of the 14 cases were found to have submucosal polyps of the digestive tract protruding growing into the cavi-ty. Perivascular onion skinning which formed by spindle fibrocytes around vascular proliferation and eosinophilic inflammatory infiltrates were present as the characteristic feature of lesions. ABC results demonstrated that the lesions showed fibroblastic, myofibroblastic and dendritic cell signs. Conclusions IFPs are rare, benign tumors that can arise throughout the digestive tract, with unique histological changes in pathology. Surgical excision or endoscopic removal is the main treatment.

Totally, 125 elderly inpatients with aspiration pneumonia (AP) were enrolled from departments of respiratory medicine and neurology at Zhongnan Hospital, Wuhan during June 2005 to October 2009 for analysis. Results showed that listlessness was manifested in 70 cases (56%), primary neurological illness in 80 cases (64%), 57 of them (46%) complicated with respiratory failure and 26 died with case-fatality of 21%. Main pathogen for them was Gram-negative bacillus, accounting for 57% of the total. Two kinds or more of antibiotics had ever been administered in 98 cases (78%), with an average length of antibiotics use for 28 days, ranging from one day to 128 days. Nasal feeding was instituted for those with choking over their feeding and coughing, and their inspired feeding was aspirated from the trachea or bronchi and lavished with bronchoscopy, with 38 cases by tracheal intubation, 26 by tracheotomy and 42 with artificial ventilation. Their average duration of hospital stay spanned 28 days with an average cost of 25 000 RMB yuan per capita, significantly higher than that for those with common pneumonia. In conclusion, clinical features of these elderly patients with AP were not so typical, most of them manifest severe, with lots of medical cost and bad prognosis.

AIM:To investigate the effects of gonadotropin-releasing hormone ( GnRH) analogue on the growth of breast cancer cell lines MCF-7 and MDA-MB-231 in vitro and to explore the related mechanisms with PI 3K/Akt or ERK/MAPK pathways .METHODS: The proliferation of human breast cancer cell lines MCF-7 and MDA-MB-231 treatment with triptorelin was detected by MTT assay and the distribution of the cell cycle was determined by flow cytometry .The phosphorylation of the ERK 1/2 and Akt was evaluated by Western blotting .RESULTS:Triptorelin inhibited the prolifera-tion of MCF-7 cells at concentration of 10-5 mol/L after treated for 192 h or at concentration of 10 -4 mol/L after treated for 168 h and 192 h.Triptorelin inhibited the proliferation of MDA-MB-231 cells at concentration of 10 -4 mol/L after treated for 192 h (P<0.05).Treatment with triptorelin for 192 h at concentration of 10 -4 mol/L had no statistical significance effect on phosphorylation of ERK1/2 and Akt(P>0.05).CONCLUSION:Inhibitory effect of GnRH analogue triptorelin on human breast cancer cells is not just the connection with the down-regulation of pituitary hormone , but also a direct in-hibitory effect.The role may not be involved in the activation of ERK /MAPK and PI3K/Akt signaling pathways .
