Tuberculosis(TB) is a chronic and debilitating infectious disease caused by Mycobacterium tuberculosis(Mtb). It is a significant health concern that poses a serious threat to human well-being. Bacillus Calmette-Guerin(BCG)is the only approved vaccine for the prevention of TB. BCG is made from attenuated bovine Mtb and is highly effective in preventing tuberculous meningitis and granulomatous TB,which are particularly lethal in infants. However,BCG provides limited protection in both children and adults,and this protective effect decreases over time. Currently,there are ongoing improvements being made to BCG,which involve modifications in immunization routes and procedures. Additionally,researchers are working on the development of new TB vaccines. BCG is primarily used for the prevention of TB and the treatment of bladder cancer,although it also has other indications. This paper reviewed the recent research progress of BCG,focusing on its development history,improvements,and indications.

In recent years,minimally invasive surgery has become the mainstream trend of modern surgery with the rapid development of endoscopic and laparoscopic techniques.However,there are limitations when either technique is used alone.The laparoscopic and endoscopic cooperative surgery (LECS),which combines the advantages and makes up the deficiencies of these two techniques,has expanded the application field of minimally invasive surgery.Laparoscopic wedge resections are increasingly applied for gastric stromal tumor.Base on clinical experience of 43 patients who underwent laparoscopic wedge resections for surgical treatment of gastric stromal tumor,we conclude that this procedure is feasible and safe.

Respiratory tract infection remains a hot clinical topic.Disappointingly, routine microbiology tests do not meet the needs of target antimicrobial therapy.Widespread practice of antibiotic empiricism has lead to dramatic use of broad-spectrum antibiotics and antimicrobial resistance.The application of new clinical microbiology tests to identify the offending pathogen may allow administration of narrow spectrum antibiotic therapy.To do so,the full clinical microbiology armamentarium with newer point-of-care tests and polymerase chain reaction tests must be exploited.The return of the sputum gram stain and introduction of newer molecular tests would provide information for judicious selection of antimicrobials.

Gastrointestinal stromal tumors (GISTs) is a subset of mesenchymal tumors and represents the most common mesenchymal neoplasm of gastrointestinal tract.In the last decade,GISTs has become well known because of the effectiveness of imatinib mesylate.The molecular targets for tyrosine kinase receptor inhibitor are not only of importance for the treatment of patients but also useful for the development of a novel drug modalities and new strategies in basic cancer therapy.The improved understanding of the molecular mechanism of GISTs has made its diagnosis standardized.Many multicenter phase Ⅱor phase Ⅲ clinical trials have been completed to establish the role of adjuvant and neoadjuvant therapy.It is important to select the correct management strategy,which is multidisciplinary,integrated,and individualized.This paper provides an overview of the rational treatment of GISTs at present.

AIM: To evaluation the efficacy dosages of topiramate (TMP) in treatment of patients with different types of epilepsy. METHODS : The seizure rate in baseline phase of patients with epilepsy were observed and recorded before treatment of topiramate as monotherapy for 20 weeks. The TMP st arting dosage was 25 mg?d -1 , and then increased to 25 mg?d -1 each week for 8 weeks until effective dosage or 200 mg?d -1 for 12 weeks, and the change of seizure frequency and adverse reactions were recorded. RESULTS: The seizure in 31 cases ( 51.7 %) was totally contro lled, seizure reduction of ≥75% was in 14 cases ( 23.3 %), ≥50% was in 4 cas es ( 6.7 %), and

OBJECTIVE: To establish a RP-HPLC method by pre - column derivatization to determine the contents of mi-cronomicin sulfate.METHODS:Kromasil C18 column( 150mm X 4.6mm,5u),mobile phasewater-ice acetic acidmethanol(30 5 : 65) in 0.02mol/L sodium -heptanesulfonate. The detection wavelength was set at 330nm.RESULTS:The linear range was 0.0 976mg/ml-0.9 760mg/ml,(r = 0.9 999),the RSD of the replicate test was 1.0%(n = 6) .CONCLUSION:The method is specific,accurate and sensitive.

Gastrointestinal stromal tumor (GIST) is the most common mesenchymal tumor in the GI tract. Surgical resection of the local disease is the gold standard therapy. In recent years, in virtue of the development of minimal invasive surgery such as laparoscopic surgery and endoscopic surgery, laparoscopic and endoscopic cooperative surgery (LECS) has been applicable for treatment of gastric GIST. This article reviewed the recent advances in LECS in treatment of gastric GIST.

Objective To explore the ultrasonographic features of fetal gastrointestinal tract dilatation and associated abnormalities. Methods From July 2009 to June 2013, 118 cases of fetal bowel dilatation of detected by prenatal ultrasound in our hospital were followed up for their ultrasonographic changes and pregnancy outcomes. The features of fetal bowel dilatation with associated abnormalities and their impact on pregnancy outcomes were summarized. Results Among the 118 cases of fetuses, 101 cases had small bowel dilatation, including 4 cases with adverse pregnancy outcomes. One case had cleft lip and palate and was aborted during 25th week of pregnancy. The other 3 cases had continuous excess of amniotic lfuid and progressive widening of bowel, the average inner diameter of which was above 30.0 mm. In the 3 cases, 2 cases ended with intrauterine death during 34th week of pregnancy and 1 case ended with death at one week after birth. Among the 97 cases of pregnant women with good pregnancy outcomes, 66 cases (66/97) were solitary bowel dilatation, while the remaining 31 cases (31/97) were associated with abnormal soft markers, e.g., excess or decrease of amniotic lfuid, fetal echogenic bowel, fetal uronephrosis, short femur, single umbilical artery, fetal widened lateral ventricles and placenta overripe, etc. Among the 17 cases of colonic dilatation, 1 case had exessive amniotic lfuid and“double-leaf sign”clumps in abdomen during the second trimester and was proved to be anal atresia post partum, while the remaining 16 cases had the colonic dilatation which were found after 34th week of pregnancy and the widest inner diameter of colon was less than 30.0 mm associated with abnormal soft markers like excess or decrease of amniotic lfuid and fetal echogenic bowel, etc., and associated with good pregnancy outcomes. Conclusions Most fetuses with mild to moderate bowel dilatation had favorable outcomes. During ultrasonic examination, the degree and dynamic change of bowel dilatation shall be observed. If bowel dilatation or increment of amniotic fluid continues or worsens, greater risk of poor prognosis is indicated. The larger inner diameter of the small bowel, the greater risk of poor prognosis. If the fetus with bowel dilatation had echogenic bowel before, the risk of intestinal obstruction is comparatively lower. For the fetus suspected for colonic obstruction and anal atresia, it is more meaningful to observe the intestinal morphology and its changes.

The bacteriology examination is a discipline of strong practicality. Fostering manipulation ability and scientific research consciousness and innovative ability of students is the key to improve the quality of teaching on bacteriology examination experiment. The author made exploration of experiment content and system,experiment inspection means and teaching media.

Type 2 diabetes(T2DM) is the collective result of insulin resistance in both muscle and liver andβ cell function failure. Traditional pharmaceutical therapy fails in ceasing progressive decline in β cell function. Bariatric surgery has been widely accepted as an efficient measure to treat diabetes. However, the prevalent standards mainly based on body mass index can not meet the demand for promoting remission rate. Related factors should be included in prediction of post-operative remission, like end-point setting, T2DM status, biochemical index, and operative method etc. The combination of these factors can be used to benefit more patients with diabetes.
