Objective:To detect the existence of expression of human augmenter of liver regeneration(hALR) in HepG2 cells,and to observe proliferation of HepG2 cells after neutralizing hALR with anti-hALR McAb.Methods:the expression of hALR in HepG2 cells was observed immunocytochemistry and reverse transcriptive PCR(RT-PCR).Proliferation of HepG2 cells after neutralization was detected by ~3?H-TdR incorporation approach.Results:① hALR was expressed by HepG2 cells.② Anti-hALR McAb inhibited partially the autonomous growth of HepG2 cells.Conclusion:Anti-hALR McAb inhibit the autonomous growth of hepatoma cells partially;moreover,hALR maintain the autonomous growth of hepatoma cells in vitro through autocrine mechanism.

Objective:To study the clinical characteristics and treatment of thrombotic microangiopathy(TMA),to improve recognition of TMA.Method:Types,clinical and laboratory characteristics,treatment and prognoses of 12 patients with thrombotic microangiopathy admitted to our hospital between October 2004 and December 2007 were analyzed retrospective1y.Result:The clinical manifestations were characterized by microangiopathic hemolytic anemia(12/12),thrombocytopenia(12/12),elevated serum LDH value(12/12),and renal lesion(12/12),fever(5/12),and neurological abnormalities or mental disorders(7/12).3 patients were treated by plasma exchange therapy.1 patient fully recovered,4 patients took a turn for the better,and 7 patients died.Conclusion:TMA is a kind of severe acute syndrome with complicated pathenogenesis and high mortality.Management should depend on the type of TMA in order to improve curative efficacy and reduce mortality.

Extrauterine growth restriction (EUGR) in premature infant is a common problem in the world. The reasons for high EUGR rate, such as declining gestational age and birth weight, getting more medical treatment and examination or interruption of nutritional support, had been profoundly studied. However, there are few reports about the limited ability of intakes of energy and various nutrients and the updating of the growth standard curve . Research suggested that the average time taken to reach the recommended fat intake in preterm infants is proximately day 6 after birth, protein day 4 after birth, carbohydrate one-week after birth. Vitamins and trace elements are usually not able to or take a long time to reach the recommended nutrient intake. Without enough intake of energy and nutrients to maintain the need of intrauterine growth rate and catch-up growth in preterm infants, EUGR cannot be improved. In this paper, the EUGR and the intake of important nutrients, such as energy, fat, protein, vitamins and minerals, etc., during hospitalization were reviewed in hope to achieve more rational and standardized management for preterm infant,and provide more reasonable advise to control EUGR.

Rational drug-use is an extremely important component part in morden medical and health work. And irrational drug-use will aggravate drug misadventure, increase overpreseribing, waste medicinal resources and harm the reputation of medical workers. The tendency of polypharmacy just for more hospital income, regardless of drug-related adverse effects, comes to be a serious problem and hard to control in recent years. No perfect management system and lack of information may be the major factors of the problem. In order to overcome the irrational drug-use characterized by polypharmacy, we should learn something from the Diagnosis Related Groups/Prepayment System (DRGS/PPS). Now, under the cooperation of The Chinese Pharmacological Society ,The Chinese Pharmaceutical Association and The Public Health Ministry of PLA, a Diagnosis Related Rational Drug-use Management System and a Computerized/Telecommunication Based Dynamic Knowledge Bank are able to be developed. We consider that it will contribute to the modernization of medical and health work in China in the near future.

The significant changes in morphology and nitric oxide synthase (NOS) activity in cultured human aortic endothelial cells (HAEC) were observed when these cells were exposed to LPS, IL-1? and IFN-?. NOS activity increased at 6h of treatment, the time point that HAEC began to change and elongate. The cell shape became fibroblast like and the length to width ratio of the cells increased 2 times of that of the control at 20h treatment, the time point that NOS activity returned to control level.

Mesenchymal stem cell(MSC) is a kind of tissue stem cell having a characteristics of high self-renewal and multipotency. It is tended to be separated in vitro and play an important role in hematopoietic stem cell transplantation and transplantation of other systems. This article described mesenchymal stem cell's function and mechanism on supporting hematopoiesis, enhancing implantation,adjusting immunity and alleviating graft versus host disease (GVHD) in transplantation and also give some advices and experties about its further application.

To investigate the cell proliferation inhibition and apoptosis induced by berberine a-hydroxy f-decanoylethyl sulfonate (HB) on MDA-MB-231 cells in vitro, and the inhibitory effect of HB on the expression of poly adenosine diphosphate RNA polymerase (PARP), MTT assay was used to detect the viability of MDA-MB-231 cells and cell cycle was examined by flow cytometry. The results showed that HB could significantly inhibit the proliferation of MDA-MB-231 cells, and mildly arrested cell cycle progression at S phase. The IC50S for 24, 48 and 72 h treatment were 4.65, 1.46 and 0.75 mg.L-1 (7.55, 2.37 and 1.22 micromol.L-1), respectively. Annexin V-FITC/PI double staining assay showed that HB increased apoptotic ratio of MDA-MB-231 cells. Western blotting analysis showed the expressions of procaspase-3, procaspase-9 and PARP were decreased after HB treatment, while their fragment increased. The results suggest that HB can inhibit the growth and induce apoptosis of MDA-MB-231 cells, which may be associated with inhibition of the expression of procaspase-3, procaspase-9 and PARP.

To evaluate the clinical effects of metronidazole-doxycycline gel for treatment of periodontitis, 18 adult patients with periodonti-tis, who had at least 4 mm of probing depth (PD) on the symmetric quadrant, were selected to participate in a randomised study with split-mouth design. Patients of the experimental group were given with metronidazole-doxycycline gel locally once a day for 7 days,while those of the control group were given with metronidazoce stilus. PD, PLI(plaque index), GI(gingival index), BI(bleeding index) were examined on days 0 and 7 of treatment. The results showed that all clinical parametres of the experimental group were better than those of the control group . Therefore, metronidazole-doxycycline gel is effective in the treatment of periodontitis.

Objective To establish an aortic transplantation model in the rat. Methods A thoracic aorta to abdominal aorta interposition transplant model in the rat was established. The male Lewis rats were used as donors and the female Brown Norway(BN) rats were used as recipients.Intercepted the thoracic aorta of lewis rats about one and a half centimeter. Transplanted it on the abdominal aorta of BN rats. The activity and weight change of BN rats were observed everyday until 1 week after transplantation. Then observed these index one time a week. The transplanted aortas were harvested at 8 weeks after transplantation. The intimal thickening were observed by pathological. The expression of CD3,CD68 and α-actin on transplanted aorta were observed by immunohistochemistry. Resuts All operations were finished within 2 hours. No recipients died during operation. All recipients could survival more than 8 weeks. The symptoms of bowing back, hair shedding and weight loss was appeared after transplantation. The weight of the rats were upturn at 4 or 5 days after transplantation. About 1 week after transplantation, all situations of the rats were recovery to the lever before transplantation. 8 weeks after transplantation the intimal thickening of the transplanted aortas were observed obviously by pathological. And the expressions of CD3, CD68 and α-actin on aortic allograft were observed. Conclusion The intimal thickening and the expressions of CD3, CD68 and α-actin on aortic allograft were typical expressions of chronic rejection. So this aortic transplantation model is feasible and reliable for studying chronic rejection.
