Objective To explore diagnosis,treatment and prognosis of intestinal atresia(IA) in neonates,so as to increase the healing rate.Methods Surgical treatment was given to 29 cases of congenital IA from Apr.2004 to Nov.2008.Comprehensive analysis was carried out on clinical manifestations and flat X-ray.All cases were with vomiting,15 cases were with normal fetal faeces.Stomach and intestinal atresia were observed in the upper abdomen in 19 cases,fluid levels in generous stomach and expended intestines were seen in 21 cases by X-ray.All children underwent operation,including ileum atresia(16 cases),duodenal atresia(7 cases),and jejunal atresia(6 cases).The types of atresia were type Ⅰ(9 cases),type Ⅱ(9 cases),type Ⅲa(9 cases),type Ⅲb(1 case) and type Ⅳ(1 case).Nine cases were treated with septum resection and then anastomosed longitudinally,3 cases underwent end-to-end anastomose and 17 underwent end-to-back anastomose.All cases were served in intravenous hyperalimentation.Results All cases lived postoperatively,and 1 child gave up for postoperatively treatment.Twenty-eight cases were cured.There was 1 case of obstruction of anastomatic,and was cured by non-operatively treatment.There was no anastomatic leakage and wound disruption.Twenty-six cases were followed up for 3 months and up to 4 years.These symptoms had no relapse.Conclusion Early diagnosis,appropriate surgical procedure and surrounding operation management are crucial for improving the cure rate.

Objective To study the susceptible factors of atherosclerotic stenosis before the coronary artery myocardial bridges.Methods The data from 88 myocardial bridge cases which received coronary angiography were statistically analyzed.Sixty-seven cages which suffered from atherosclerofic stenesis in proximal of the myocardial bridges were recruited into group A,and the other 21 cases which suffered no atherosclerotic stenosis or from atherosclerotic stenosis in distal of the myocardial bridges were mcmited into group B.Difference of the age,gender,length of myocardial bridge,systolic blood pressure (SBP),diastolic blood pressure (DBP),pulse pressure (PP),the oppression degree of myocardial bridge (Nobel classification),fasting plasma glucose (FPG),and blood fat,and so on,in two groups,were observed and statistically analyzed.Results The difference of the Nobel classification,SBP and PP in two groups showed a statistical significance (P＜0.05).While the difference of the age,gender,length of myocardial bridge,DBP,FPG,total cholesterol,low-density hpoprotein in two groups showed no statistical significance (P＞0.05).A further regression analysis suggested that Nobel classification and PP had a correlation with the comphcation of stonosis before the myocardial bridge (r=3.0569,0.9740,P＜0.05).Conclusions High blood pressure cases are liable to suffer from myocardial bridge.Myocardial bridges themselves trend to promote or accelerate the atherosclerotic stenosis of the coronary arteries before.them.The oppression degree of myocardial bridge and PP has a correlation with the complication of stenosis before the myocardial bridge,while has no correlations with age,gender,bloodfat,SBP,DBP,FPG,length of myocardial bridge,and so on.

When looking back to the literature regarding insomnia, it is believed that "disharmony of stomach leads to insomnia" is an important mechanism for the attack of insomnia. This theory is widely accepted in clinical practices by ancient and modern acupuncturists, thus the method treating insomnia from the stomach is developed. But deeper research on its mechanism is still lacking. Through correlation between stomach meridian and heart meridian, spleen and stomach being the pivot of rise and decline of qi movement and yin-yang and being the pivot of five zang-viscera housing spirit, modern abdomen-brain theory and experimental research, the mechanism of treating insomnia from the stomach is discussed in this paper, so as to be better to guide clinical acupoint-selection and treatment.

MTT Colorimetric method is usually applied for measuring the living animal cell number. By changing the reaction temperature and the reaction time as well as the colorimetric wavelength, the improved MTT colorimetric method was established to count the living bacterial cell number. This new method was used to measure the living cell concentration in the process for culturing bacteria PBW1. The results measured by the improved MIT colorimetric method and dilute plate method are similar. Compared with other methods including the dilute plate method, the improved MTT colorimetric method has many advantages such as accuracy, quickness.

Organic solvent tolerant microorganism(OSTM) is a novel extremophile and it hasn't been systematically studied until 1980s.Relying on certain mechanisms,the OSTM is able to effectively de-fend and decrease the toxicity from organic solvents,which enable the OSTM to be potentially applied in the industrial fields such as whole-cell catalysis and environmental treatment,etc.The comprehen-sively understanding of the mechanisms involved in organic solvent tolerance of OSTM could be com-bined with genetic engineering in order to modify and optimize the various specifications of OSTM,and further broaden its application in other industrial areas.Latest studies on the tolerant mechanisms of OSTM,in this paper,will be reviewed from four aspects such as vesicle exocytosis and changes of phos-pholipid composition in membrane,etc.Besides,the application of OSTM in whole-cell catalysis and other fields will be introduced.

Objective To evaluate the myocardial blood supply in patients with metabolic syndrome (MS) using 99Tcm-MIBI SPECT MPI. Methods A total of 342 patients were divided into four groups according to the number of abnormal metabolic indices: no abnormal metabolic index (Group 1), one abnormal index (Group 2), two abnormal indices (Group 3), three or more abnormal indices (Group 4). Each patient underwent two-day protocol of gated stress and rest 99Tcm-MIBI MPI. One hundred and three of the 342 patients were clinically diagnosed as MS and underwent CAG within 1 month after MPI. χ2test was used to evaluate the difference among the four groups and Kappa test to analyze the correlation between MPI and CAG. Results Compared with CAG, the diagnostic sensitivity, specificity, positive and negative predictive values by 99Tcm-MIBI SPECT MPI for coronary artery diseases (CAD) in 103 MS patients were 80.5% (33/41), 85.5% (53/62), 78.6% (33/42) and 86.9% (53/61), respectively. The correlation coefficient between MPI and CAG was 0.657 (P<0.001). The abnormal MPI rates in group 1, 2, 3 and 4 were 23.3% (10/43), 32.9% (26/79), 54.4% (56/103), and 57.3% (67/117), respectively (χ2=23.22, P<0.001). Conclusions In MS patients,99Tcm-MIBI SPECT MPI can be useful for evaluating myocardial blood supply and the myocardial ischemia rates may correlate positively with the number of abnormal metabolic indices.

OBJECTIVETo systematically assess the efficacy and safety of Rhodiola in treating chronic stable angina pectoris.

METHODSOur group searched the Cochrane library, PubMed, Embase, Chinese biomedical literature database (CBM), VIP database (VIP), Chinese Journal Full-text Database (CNKI) for the literature published in English and Chinese till April 2013. Randomized controlled trials (RCTs) were included on the therapeutic effect of Rhodiola or Rhodiola plus conventional Western medicine in comparison with the conventional Western medicine treatment on stable angina. Data were extracted according the data extraction form. The literature methodological quality was assessed by using the Cochrane handbook, and data analyzed by Rev-Man 5.2 Software for Meta-analysis. The effect indicators of outcomes was expressed by odds ratio (OR) and 95% CI.

RESULTSA total of 7 randomized controlled trials, 662 cases of stable angina pectoris patients met the inclusion criteria and all published in Chinese, without one scientific design and high quality literature. Compared with the conventional Western medicine treatment, combined with oral administration of Rhodiola could improve the efficiency of anti-angina (OR = 2.49, 95% CI: 1.02 - 6.09). Combined with intravenous infusion of Rhodiola could also improve the efficacy of angina pectoris (OR = 4.86, 95% CI: 2.4 - 9.82). Oral administration of Rhodiola couldn't improve ECG efficacy (OR = 1.25, 95% CI: 0.67 - 2.34). Intravenous infusion of Rhodiola could improve the clinical efficacy (OR = 2.94, 95% CI: 1.61 - 5.35). Combined with the conventional treatment, intravenous infusion of Rhodiola could improve the whole blood viscosity (low and high shear rates) and inverse variance (IV) (-1.36 and -0.99, 95% CI: -1.65 - 1.07 and -1.26 - 0.71), but could not reduce serum fibrinogen and D-dimer level. The incidence rate of adverse reactions was higher than that of the conventional treatment combined with Rhodiola (OR = 0.1, 95% CI: 0.02 - 0.51).

CONCLUSIONSOn the basis of routine treatment, Rhodiola could further improve patients' symptoms. Combined with intravenous medication, Rhodiola could increase the ECG improvement rate, and reduce adverse reactions. But the methodological quality of included studies was poor, the number of samples was small, and influence factors such as the intervention period was short. This conclusion needs scientific and rational design in a larger sample, multicenter clinical trial to verify.
