In recent years,some investigations show that gut barrier dysfunction induced by severe acute pancreatitis was an important factor to determine the prognosis. Consequently, pathogenesis, monitoring standard was and treament of pancreatitis associated gut barrier dysfunction are becoming hot spots.

Objective To study whether ANCA liter is sensitive serological marker reflecting vasculitis disease activity. Methods MPO-ANCA and IF-ANCA tilers variation in five sera specimen with active MPA diseases were studied after methylprednisolone and cyclophosphamide pulse therapy. The clinical and pathological features of 5 patients with MPA were investigeted comparing pre-treatment with post-treatment. Results (1) Serum ANCA were found positive and increased liter in 5 patients wilh active MPA disease. (2) Titer decreased after Ireatment, while renal function improved. (3) After half year, MPO-ANCA was negative in 5 patients, IF-ANCA was negative in 2 patients. Conclusion There is a close correlation between serum ANCA titer and MPA renal disease activity.

Cisplatin,carpolatin and oxaliplatin are platinum-based drugs that are widely used in cancer chemotherapy. Peripheral neuropathy is major dose-limiting side effect of platinum-based drug. Accordingly, this side effect restrict its clinic application. This review will focus on the research advancement on the mechanism of dorsal root ganglia neurons apoptosis in cellular and molecular biology.

For the cultivation of medical students medical professionalism and evaluation has become a hot is-sue in the medical colleges medical education at home and abroad, but for junior medical students′professional spirit evaluation research is less.This paper introduces the basic concept of responsibility index and application by introducing foreign medical schools responsibility index for evaluation in school doctor students physician profession-alism, analysis the advantages and disadvantages of the method.Think the responsibility index is based on the spe-cific behavior evaluation, the result is more accurate, is suitable for junior medical students′professional spirit e-valuation system, compared with other evaluation system, responsibility index, pay more attention to guidance and specification in advance.But responsibility index also has some disadvantages.Such as responsibility index evalua-tion process must face some ethical challenges, lack of integrity and evaluation framework design.

BACKGROUND:Moderate to severe burn and trauma, treatment of which has been paid equal attention to wound surface, is always a difficulty of clinical systemic treatment and has a poor prognosis. Anabolic hormones have acquired secure and good results in the treatment of burns in both animals and clinical patients. Although use of anabolic hormones is restricted by the doping management, but its androgen receptor and nuclear receptor coregulators are the newly emerging areas of interests in the field of gene regulation mechanism in recent years. OBJECTIVE:To investigate the effect of nandrolone phenylpropionate on androgen receptor-mediated transcriptional regulation of target gene in rat scald models. METHODS: Thirty-six rats were randomly divided into nandrolone phenylpropionate, model and control groups. In the nandrolone phenylpropionate and model groups, rats were subjected to a 20% total body surface area second-degree scald injury by hot water. Two days after model preparation, rats in these two groups were intramuscularly injected with nandrolone phenylpropionate and saline, once every other day, for a total of 21 days. RESULTS AND CONCLUSION:The gene expression levels of steroid receptor coactivator-1 and insulin-like growth factor 1 in the rat livers and gonads (testes, ovaries) were significantly different between the nandrolone phenylpropionate and model groups (P < 0.05), except steroid receptor coactivator-1 in the liver. There were no significant differences in steroid receptor coactivator-1, c-myc and insulin-like growth factor 1 in the rat livers and gonads (testes, ovaries) between model and control groups (P < 0.05). The results demonstrate that nandrolone phenylpropionate has different effects on the gene expression of steroid receptor coactivator-1, c-myc and insulin-like growth factor 1 in different tissues under different physiological and pathological conditions.

Spinal cord injury is a common clinical disease .Cell apoptosis is one of important pathogeneses for spinal cord in-jury, and apoptotic gene plays a very important role in apoptosis on spinal cord injury .Chinese medicine for blood-activating and stasis-dissolving has a good therapeutic effect for spinal cord injury by reducing inflammation , inhibiting apoptosis and improving microcircu-lation.In this paper, we review the research of chinese medicine for activating blood and resolving stasis during the regulation of apoto -sis gene in spinal cord injury based on related documents in the recent five years .

K-ras gene is one of oncogenes in non-small cell lung cancer,and it can promote tumor cells growth after mutations by several signaling pathways.K-ras mutations frequently occur in lung adenocarcinoma patients with smoking history.In the present study,K-ras mutations are associated with resistence to targated therapy and may be a marker of poor prognosis in patients with non-small cell lung cancer.

Objective To investigate the predictive value of serum histone deacetylase 3(HDAC3) ,cystatin C(CysC) and albu‐min levels on a large area of myocardial infarction .Methods According to whether heart failure and (or) cardiogenic shock occur‐ring during hospitalization ,102 patients with acute myocardial infarction(AMI) were divided into the two groups :the non - compli‐cating heart failure and (or) cardiogenic shock group(n= 63) and the complicating heart failure and (or) cardiogenic shock group(n= 39) .Then according to whether the creatine kinase(CK‐MB) peak value was greater than 200 IU /L ,102 AMI patients were di‐vided into two groups :CK‐MB peak values ≥ 200 IU /L group(n= 58) and the CK‐MB peak values < 200 IU / L group(n= 44) .The serum HDAC3 ,CysC and albumin levels were detected at early morning on 2 d of admission in all patients .Results Compared with the non - complicating heart failure and (or) cardiogenic shock group ,serum HDAC3 and CysC levels in the the complicating heart failure and (or) cardiogenic shock group were significantly increased(P< 0 .01) ,while serum albumin protein level was significantly in the occurrence of heart failure and(or)cardiogenic shock group .Compared with the CK‐MB peak value < 200 IU /L group ,serum HDAC3 and CysC levels in the CK‐MB peak value > 200 IU /L group were significantly increased (P< 0 .01) ,while serum albumin level was significantly decreased(P< 0 .01) .Conclusion Serum HDAC3 ,CysC and albumin levels have certain predictive value on a large area of myocardial infarction and conduce to judge the prognosis of patients .

Laparoscopic hepatectomy has been utilized in clinic,however to some extent there are some limitations for various equipments being used in laparoscopic hepatectomy, as a result, the laparoscopic bepa-tectomy is being constrainted on its development. Therefore, with the research and development of the ideal tool for laparoscopic hepatectomy,laparoscopic liver surgery is bound to be booming.
