1.RAPID BIOCHEMICAL SYSTEM FOR IDENTIFICATION OF AN AEROBIC BACTERIA
Chinese Medical Equipment Journal 1989;0(04):-
We reported here a rapid biochemical system for identificationm of anaerobic bacteria by directly detecting cnzyme produced by cultured anaerobic colonial cells. Anaerobic bacteria suspension was prepared in pH7.4 bouillon yeast solution, a series of different substrates was added,then the mixture was incubated in 37~C for 4-6 hours.Various specific reactions could be shown by adding indicator or reagents.Our system is modified fromAPI 20 and similar to AN-IDENT,RAPID- ANA rapid enzyme methods 12 anaerolic strains of international standard were detected usind this system,the corresponding rate was 92.3%,while the average corresponding rate arrived at 87.5% after detecting 192 strains isolated in hospitals. We coneluded from the results thot this system is a rapid,simple and specific method for identification of anaerobic bacteria and can be applied to clinical and experimental use.

AIM To study the protective and mechanism of Tfa (total flavone of the flowers of Abelmoschl Manihot L. Medic). METHODS The rats were injected Iso and then the T wave movement value observed. The rats anterior descenging bracnch of left artery were occluded for 48 hours the results of CPK, LDH and disscoate fatty acid of serum and infarct area of myocardium observed. RESULTS Tfa 100,200 mg?kg -1 ,ip depressed the T wave rise by injection of Iso in rats. Tfa 100 mg?kg -1 ?d -1 ?3,ip inhibited the serum CPK and LDH disscoate fatty acid in myocardium induced by coronary artery occluded in rats;also markedly depressed the infarct area in myocardial infarct rats. Tfa 0 03 mg?kg -1 ?d -1 ?3,ip obviously reduced the MDA contents,increased SOD and GSHPx activities in the mitochondria in mice. CONCLUSION Tfa shows a protective effect against myocardial injury. The mechanism may be via against oxygen free radicals and lipid peroxidation,also stabilize the mitochondria function.

Aim This study was to examine the effect of ethyl acetate extract of shiitake mushroom on a human breast cancer line-MCF-7 cell in vitro. Method Cell cytotoxicity was examined using MTT method, Cell apoptosis was examined by AnnexinV-FITC/PI staining,Cell cycle analysis was determined by flow cytometry. Western blot analysis was used to determine Cyclin D_1、Cdk4、Bax and p21WAE1/CIP1 protein expression. Results Concentration-dependent cytotoxic effects of the extract were observed in MCF-7 human breast cancer cell lines. Pro-apoptotic proteins (Bax, p21WAE1/CIP1)were up-regulated while proteins involved in cell cycle(Cyclin D_1 and Cdk4)were down-regulated. Conclusion This study suggests that the anti-breast cancer activities might result from increased apoptosis and growth arrest

Teaching of medical ethics is important in making up intems'diathesis.Recognition of the relatinship between doctor and patient is an important way for promoting their socialization and specialization since it is the basic relationship which interns face during clinical practising.Only by properly dealingwith the relationship can interns take to strengthen medical ethics study and culture medical moral consciously.

Objective:To explore the subjective quality of life of pediatric patients.Methods:42 children with acute diseases, 38 with chronic diseases and 57 normal children were investigated with Children's Subjective Quality of Life Questionnaire. Results: The subjective life satisfaction were similar in acute disease group (159.9?13.9) and in chronic group (160.0?16.9), which were lower than normal control (165.8?17.6). Multiple regression showed that girls, from urban area, late onset, longer duration, less activities out of class, lack of support from relatives, poor mental health of parents were risk factors. Conclusion: Children with acute or chronic diseases have poorer life quality than normal control.

After the necessity to compile n the union catalog of minority nationality medical documents in Yunnan Province was analyzed according to the scattered collection of minority nationality medical information resources and no available standard minority nationality medical documents catalog, how to compile it was discussed from the aspects of the collection and catalog organization of literature information resources, and quality control of bibliographic data, in order to construct the support system for minority nationality medical information resources.

Objective To understand the clinical distribution of Acinetobacter baumannii and its resistance to commonly used an‐tibiotics so as to provide the theoretical basis for rational clinical use of antibacterial medicines .Methods The clinical distribution and drug resistance situation of 206 strains of clinically isolated Acinetobacter baumannii in the Anhua County People′s during 2012-2014 were analyzed .The bacterial identification was completed by the department of clinical laboratory ,the drug susceptibili‐ty test was performed by adopting the disk diffusion method ,and the detection results were judged according to CLSI 2012 criteria . Results A total of 2 803 strains of bacteria were isolated during 2012-2014 ,including 206 strains of Acinetobacter baumannii .Its constituent ratios during this period were 6 .71% ,6 .82% and 8 .19% ,showing the increasing trend year by year .The samples were mainly isolated from sputum (78 .16% ) ,followed by urine (7 .28% ) ,bronchoaleolar lavage fluid (6 .80% ) ,wound secretion (3 .40% ) and blood(2 .91% ) .The infected patients were mainly distributed in the respiratory department (40 .29% ) and neurosur‐gery department(22 .82% ) .The detection results of Acinetobacter baumannii showed the higher resistance to 20 kinds of commonly used antibacterial drugs ,in which the drugs with most significantly increase in 3‐year drug resistance rate were in turn ceftazidime , cotrimoxazole ,levofloxacin ,piperacillin and ciprofloxacin ,the 3‐year resistance rate to meropenem ,imipenem ,cefoperazone/sulbac‐tam and cefepime was less than 35% .Conclusion Acinetobacter baumannii is the major opportunistic pathogenic bacterium in noso‐comial infection with higher drug resistance rate .It is necessary to strengthen the monitoring of Acinetobacter baumannii drug re‐sistance and rationally use antibacterial medicines in order to stop the drug‐resistant strains colonization and cross expansion in hos‐pital .

Over the past several decades of innovation and development, Ilizarov technique has been widely recognized and applied in correction of limb deformity and post-traumatic sequelae with outstanding clinical outcomes, which making remarkable contributions to the development of orthopaedics. There is no doubt that tissue regeneration induced by tension-stress is the core of Ilizarov technique, and a series of biological cascades contributing to tissue regeneration could be triggered by mechanical stimulation through signal transduction including bone morphogenetic proteins regulations, inflammatory responses and immune responses, angiogenic activities, stem/progenitor cell homing and other systematic effects. One of main limitations of Ilizarov technique is slow rate of new bone mineralization. To facilitate this technique application better in clinical practices, a multitude of researches of means for promoting bone mineralization have become hot spots in this field in recent years, such as physical measures, chemicals and biological therapies. With better understanding of distraction histogenesis for promoting tissue regeneration, transverse tibial bone transport has been increasingly applied to vascular disease management in lower extremity, such as diabetic foot and thromboangitis obliterans. This review focuses on the recent advances in understanding the basic biological mechanisms of Ilizarov technique and new methods for promoting bone consolidation in distraction areas, providing evidence and ideas for further mechanism investigations and approach innovations.
