Objective To study the role of protein kinase B(PKB) in gastric cancer BGC-823 cells treated by TPA. Methods Flow cytomety(FAC) and fluorescence microscope were used to detect the effect of TPA on gastric cancer BGC-823 cells,after cells were treated by BrdU and stained by DAPI,respectively.The effect of TPA on the expression level of PKB protein and its phosphorylation of Ser 473 and Thr 308 were investigated by Western blotting.When nuclear and cytoplasmic protein fractions were prepared through lysis of cell and centrifugation,the effect of TPA on the expression level of PKB protein and its phosphorylation of Ser 473 in cytoplasm and nuclei were detected by Western blotting.Meanwhile,the effect of TPA on the distribution of PKB was observed under laser-scanning confocal microscope with immunofluorescence technique. Results TPA induced the apoptosis of gastric cancer BGC-823 cells.It also induced the inhibition of PKB protein expression in a TPA concentration-dependent and time-dependent manner in gastric cancer BGC-823 cells,regardless of dephosphorylation of PP2A.TPA inhibited the phosphorylation of PKB at Ser 473,but it did not affect its phosphorylation at Thr308.TPA only attenuated the expression level of PKB and its phosphorylation of Ser 473 in nuclei,whereas it did not change the distribution of PKB in BGC-823 cells.Conclusion These data suggest that the inhibition of PKB plays an important role in mediating the effect of TPA in gastric cell line.Apoptosis induced by TPA is partly due to the inhibition of PKB and its phosphorylation of Ser 473 in nuclei.

Objective To explore the clinical value of the insulin pump(CSⅡ) and multiple subcutaneous insulin intensive treat-ment(MDI) for patients with type 2 diabetes and stroke .Methods A total of 80 patients with type 2 diabetes and stroke in Weifang Community Health Service Center from April 2011 to May 2014 were selected as subjects and divided into experimental group and control group according to random number table method ,with 40 cases in each group .Patients in the experimental group were trea-ted with CSⅡ ,patients in the control group were treated with MDI .Glucose level ,therapeutic time ,the number of low blood sugar , insulin dosage ,National Institute of Health Stroke Scale(NIHSS) score ,insulin secretion index(IS) ,insulin resistance index(IR) , hospital costs were compared before and after treatment in the two groups .Results The glucose levels ,therapeutic time ,the num-ber of low blood sugar ,insulin dosage ,NIHSS score ,IS ,IR in the two groups before and after breakfast ,before and after lunch ,be-fore dinner ,after dinner 2 hours before treatment had no significant differences(P>0 .05) ,the glucose levels ,therapeutic time ,the number of low blood sugar ,insulin dosage ,NIHSS score ,IS ,IR after treatment in both groups were significantly decreased at these time points ,but those indicators in the experimental group decreased more significantly ,and had significant differences with those of the control group(P<0 .05) .The cost of hospitalization of patients in the experimental group was significant lower than that in the control group(P<0 .05) .Conclusion CSⅡ treatment for type 2 diabetes and stroke patients ,not only control glucose level well ,re-duce the number of low blood glucose and insulin dosage ,significantly improved IS and IR ,reduce hospital costs ,and also could sig-nificantly improve the neurological disorders of consciousness ,which is an ideal treatment method compared with MDI .

BACKGROUND:An increasing number of studies have shown that mesenchymal stem cels have the potential to treat acute kidney injury. Umbilical cord-derived mesenchymal stem cels have general characteristics of stem cels and many advantages, such as easy to isolate and culture, in vitrofast amplification, low immunogenicity and no ethical problems, which have garnered increasing attentions. OBJECTIVE:To study the repairing effects of human umbilical cord-derived mesenchymal stem cels on acute kidney injury in rats. METHODS: Thirty rats were randomized into three groups: a normal control group, a model group and a cel transplantation group. Rats in the model and cel transplantation were subjected to clamping the renal pedicles for 45 minutes, and then injected 1 mL of DAPI-labeled umbilical cord-derived mesenchymal stem cels or 1 mL of saline via the tail vein. In the normal control group, the kidney was only exposed with no treatment. At 7 days after treatment, the rats were kiled to take left kidney tissues for pathological observation under light microscope and right kidney for observation of DAPI-positive cel counting. Automatic biochemical analyzer was used to detect serum creatinine and urea ammonia levels. RESULTS AND CONCLUSION: Compared with the model group, the levels of serum creatinine and urea ammonia were significantly lower in the cel transplantation group (P < 0.05), suggesting that human umbilical cord-derived mesenchymal stem cels can improve the kidney function to a certain extent. Pathological findings showed that the pathological damage was improved more remarkably in the cel transplantation group than the model group, and the tubular necrosis index decreased significantly in the cel transplantation group. At 7 days after cel transplantation, blue fluorescent cels were scattered on renal tissue frozen sections. These results indicate that human umbilical cord-derived mesenchymal stem cels can migrate to the injured tubular epithelial tissues, and promote the repair of the injured kidney.

Objective To investigate the epidemiological characteristics of adverse reaction induced by Chinese herbal injection. Methods Multiple cases report in domestic medical periodicals were searched and analysed by bibliometric and statistic meth-ods. Results Fifty-six reports on muti-ADR cases related to 16 different kinds of Chinese herbal injection were collected. There were 67299 patients and 1348 ADR cases related to Chinese herbal injection. The average ADR incidence was 2.00 % ;the highest incidence of 43.28 % was shown in cinobufotalin injection and the lowest incidence of 0. 25 % in zedoary turmeric oil injection). Skin lesion, and circulatory and digestive lesion dominated in ADRs. Conclusion we should use Chinese herbal in-jection more rationally, and enhance prevention awareness to reduce the incidence of ADR induced by Chinese herbal injection.

BACKGROUND: As a specially differentiated central nerve, optic nerve is once injured, retinal neurons are hard to restore and regenerate. As a result, visual function is lost permanently. Currently, an effective clinical treatment is not available. Due to the multi-directional differentiated potential of stem cells, their role in optic nerve protection and restoration following injury is becoming a hot research spot.OBJECTIVE: To review the classification and transplantation of stem cells in optic nerve protection study, as well as roles of stem cells transplantation in optic nerve protection and repair following injury.METHODS: The database of ISI Web of Knowledge platform was searched on computer from February 1994 to April 2009, with the key words "stem cells, optic nerve" in English. In the same way, the database of CNKI from February 1994 to April 2009 was also screened, with the key words "stem cells, optic nerve" in Chinese.RESULTS AND CONCLUSION: A total of 98 literatures related to stem cells in optic nerve protection and restoration after injury are collected, in which 23 papers are Chinese and 75 papers are English. The studies published earlier, repetitively and similarly are removed, and 38 papers which comply with the standards are involved into this review. Stem cells own the potential of self-renew physiologically, as well as potential of repairing the injuries. At present, most of the researches on stem cells in optic nerve protection and restoration after injury are represented in morphosis. How to implant stem cells safely and effectively and how to recover stable visual function still need our efforts. Stem cells derived from skin, peripheral blood, fat and other tissues are convenient to draw materials and are commendable subjects, we should study them deeply to make preferable use.

OBJECTIVE:To establish a RP-HPLC method for the determination of Chlorogenic acid in Pneumonia mixture. METHODS: The separation of samples was performed on a column of Spheri-5 RP-C18 (250 mm?4.6 mm,5 ?m). The mobile phase consisted of acetonitrile-0.4% phosphate (8.5∶91.5) with a flow rate of 1.0 mL?min-1.The detection wavelength was set at 328 nm. RESULTS: The calibration curve was linear in the range of 5.00～100.00 ?g?mL-1 for Chlorogenic acid(r=0.999 9).The average recovery was 98.15%,(RSD=3.68%,n=6).CONCLUSION: The method was rapid, simple and accurate, and it can be used for the quality control of Pneumonia mixture.
