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 .

Objective To evaluate the relationship between thyroid autoantibodies (ATA)and pregnancy outcome of infertility women after assisted reproductive technology (ART). Methods Relevant studies were identified by searching PubMed, Cochrane library, CNKI and CBM. Results 7 studies were appropriate for meta-analyses and total 4165 patiens were included. Meta analysis shows that the pregnancy rate difference between ATA positive patients and controls have no significance, but the miscarriage rate is greater significant between them. In the meta-analyses, the presence of thyroid antibodies was associated with an increased risk of miscarriage (OR 1.85, 95%CI 1.32~2.59), compared with the absence of thyroid antibodies. Conclusion Pregnant women with thyroid antibodies have an increased risk of complications, especially miscarriage. Future research,should focus on the treatment and thyroid disease on pregnancy outcome.

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.

Objective To evaluate the influence of ProTaper rotary nickel-titanium files root preparation on root canal filling . Methods 30 cases of molars pulpitis and 20 cases of premolars pulpitis or periapical periodontitis were equally divided into two groups .The group A(30 cases) used the ProTaper rotary nickel-titanium files in root canal preparation and the group B (30 cases) adopted the common K files modified step-back technique for root canal preparation .The influence of the root preparation by 2 sets of apparatus on the effect of root canal filling ,and the several aspects of the root canal filling time ,the matching degree of main root canal file and master gutta-percha ,proper filling rate ,postoperative reaction of root canal filling were compared for conducting the e-valuation .Results In the mean root canal filling time of the group A ,average premolar time was 4 min 25 s and molar was 1 min 30 s ,however in the group B ,average premolar was 5 min 30 s and molar was 11 min 41 s ,the time in the group A was greatly short-ened with statistical difference(P<0 .05);the matching degree of main root canal file and master gutta-percha in the group A was 86 .37% for premolar and 88 .89% for molar ,however in the B group ,which was 62 .50% for premolar and 26 .67% for molar ,the matching degree in the group A was greatly improved with statistical difference between them (P<0 .05);the proper filling rate of upper premolar from the X-ray film was 72 .73% in the group A and 70 .83% in the group B ,while which of molar was 80 .0% in the group A and 77 .78% in the group B ,here was no statistical difference between them (P>0 .05);the postoperative pain reaction of root canal filling in both groups were very low and weak without statistical difference .Conclusion The ProTaper rotary nickel-titanium files root preparation can accelerate the root canal filling speed ,improve the matching degree of main root canal files and master gutta-percha and simplify the root-filling therapy procedure .

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.

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.

Objective: To investigate prognostic factors of survival of lung adenocarcinoma patients with brain metasta-ses.Methods: The clinical data of 109 lung adenocarcinoma patients with brain metastases were reviewed.Fifty-senven pa-tients survived more than 1 year, and 52 patients survived less than 1 year.The data were analyzed by SPSS 15.0 statisti-cal software.Results: Both the univariate analysis and multivariate analysis showed that patients' PS score, the interval be-tween diagnosis and brain metastasis, and multimodality treatment were independent prognostic factors for the survival of lung adenocarcinoma patients with brain metastases (P<0.05).Patients' gender, age, metastatic symptoms and extracrani-al metastases didn't significantly affect patient survival.Conclusion: Patients with PS score 0-1, the interval of more than 1 year between diagnosis and brain metastasis, and combined therapy have longer survival.The research provides an impor-tant guidance for the treatment of advanced lung adenocarcinoma patients with brain metastases.

Budd-Chiari syndrome is an uncommon but often fatal disorder resulting from obstruction of hepatic venous outflow tract at the level of the hepatic veins,the inferior vena cava. The CT and MRI charac-teristics of Budd-Chiari syndrome are reviewed in this article especially for displaying the exact site and extent of the obstruction. In addition to this direct sign,the indirect findings of venous obstruction such as the presence of intra-and extrahepatic collateral veins,caudate lobe enlargement,inhomogeneous liver enhancement,and regenerative nodules can also be demonstrated. Awareness of these findings is important for early diagnosis and appropriate treatment.

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.
