OBJECTIVE To understand the susceptibility to antituberculous agents for patients with primary and acquired drug resistance of Mycobacterium tuberculosis. METHODS M. tuberculosis positive sputum samples were collected from Jun to Dec 2006. Ameliorative Lowenstein-Jensen culture medium was used to detect bacillus-positive specimen of pulmonary tuberculosis by typing using PNB and TCH. Totally 217 samples were confirmedtobe positive by culturing. Drug susceptibility test against streptomycin (SM),isoniazid (INH),rifampicin (RFP) and ethambutol (EMB) was conducted. RESULTS The total drug resistance rate was 65.90%,the initial drug resistance rate was 39.81% and the initial multi-drug resistance rate was 16.67% ;the acquired drug resistance rate was 91.74%,and the acquired multi-drug resistance rate was 74.31%. The main causes of drug resistance were irregularit of treatment at beginning and preterm stop of the freatment course by patients own selves,which accounted for 71.6%. CONCLUSIONS The drug resistance of M. tuberculosis is caused by irregular treatment,so the key to prevent and control drug resistance is rational and whole-course treatment.

Traumatic asphyxia is a result of sudden or severe compression of the thorax and/or the upper abdomen.A sudden increase of intravascular pressure transmitted to the intra-and extracerebral vessels may cause petechial hemorrhage in the brain and in the skin over the head,face,neck and shoulder regions.Severe cerebral anoxia accompanying the injury may lead to cerebral edema and the appearance of signs of increased intracranial pressure as well as ARDS following hypoxemia.Spinal puncture and EEG are helpful in early diagnosis.The essential therapeutic measures consist of improvement in ventilation,dehydration and the use of glucocorticoid hormones.By such manoeuvres,11 of 12 patients we treated recovered satisfactorily and only 1 of them succumbed.

OBJECTIVE:To provide suggestions and countermeasures for improving the accessibility of national essential medi-cines. METHODS:Based on the theoretical analysis,the questionnaire was designed for the pre-survey and formal survey on the experts from universities,enterprises,government agencies and non-governmental organizations,and analytic hierarchy process was used to analyze and discuss the valid questionnaire. RESULTS:Totally 35 question naires were sent out and 27 were effective-ly received with effective rate of 77.14%. The physicians and pharmacists’cognition of essential medicine system and essential medicine,and the reasonable degree of public bid prices of essential medicine,the fairness and impartiality of essential medicine bidding process were the key influential factors;the prescription,provision,reimbursement of essential medicine,and the financial compensation to primary public health care institutions that sell essential medicine by zero-slip were the secondary factors;primary health care institutions’monitoring on the use of essential medicine(such as prescription rate,etc.),the participation of social se-curity sector in bidding and purchasing of essential medicine,the reasonable degree of pricing of essential medicine,the monitoring of the price of essential medicine,and the compensation to manufacturers of essential medicine were the general factors. CONCLU-SIONS:The accessibility of essential medicine involves many stakeholders,whom impact from different levels. Therefore,all rele-vant stakeholders should be coordinated to gradually improve the accessibility of essential medicines.

Objective Evaluate the immunotoxicity of Ginenoside Compound K Injection.Methods Active Systemic Anaphylaxis (ASA)tests and Passive Cutaneous Anaphylaxis (PCA)tests were used to evaluate Ginenoside Compound K Injection.Results In the ASA tests,positive control group showed pole-strength anapbylaxis,both the high-dose group and the low-dose group of Ginenoside Compound K Injection didn't produce allergic reaction and the body weights of all groups showed no significant differences.In the PCA tests,all rats of positive control group caused blue spots with their diameters bigger than 5 mm (diameters on the left side of blue spots was (10.1± 3.34) mm and diameters on the right side of blue spots was(7.57± 1.94)mm.Serum IgE was significantly increased.While both high dose and low dose of Ginenoside Compound K Injection group didn't show blue spots with their diameters greater than 5 mm and their IgE levels showed no significant differences compared with negative control group.Conclusion Ginenoside Compound K Injection showed no immunotoxicity under these experimental conditions.

The in vitro modulation effect of insulin on DNA and IL-2 production of spleen lymphocytes in diabetic mice were studied. The results suggest that the DNA and IL-2 production of the lymphoc-ytes are significantly inhibited in the mice. When suspend the lymphocytes to the culture medium containing insulin, the DNA and IL -2 production of the lymphocytes are remarkably increased. Therefore, insulin is an important immunoregulation hormone.

Objective To investigate the relationship of cardiac function and ventricular structure with the training intensity and the periods lived in Tibet.Methods Sixty recruits to Tibet were selected and examined of their cardiac function,cardiac ventricular structure and the changes of elctrophysiology by color Doppler echocardiography and electro cardiogram.They were examined continuously in two years.After their training for three months together,they were divided into the different training intensity groups,Group A and Group B.The 30 recruits in Group A had high-intensity training,and the others in Group B had normal training.Results After three months,their cardiac function and ventricular structure had obvious difference in comparison with the level on plain( P 0.05 ).But there were obvious differences between in Tibet and on plain in the parameters of cardiac function and ventricular structure two years later( P 0.05 ).Conclusions Hypoxia can effect the cardiac function and ventricular structure directly.After three months in Tibet,cardiac function can fit the condition of hypoxia.The parameters of cardiac function are still less than those on plain.The right ventricules are bigger and the pulmonary arteries wider as the main character of the ventricular structure changes.The indexes of cardiac function showed no significant difference with the training intensity and the periods in Tibet.

Objective To map the mutation gene of autosomal dominant congenital lamellar cataract in a family pedigree of four generations.Methods A Family with non-syndromic congenital cataract was recruited from the Eye Center of Tongren Hospital affiliated to Capital Medical University.Family history was recorded.Twenty-eight members of the family pedigree(including twelve affected and sixteen unaffected individuals)were enrolled into the study with informed consent.The twelve affected individuals underwent full clinical and ophthalmological examinations to rule out any concomitant disorders.The sixteen unaffected individuals only underwent ophthalmological examination.Blood samples were collected from all the 28 subjects for genomic DNA preparation.Eighteen different genes were previously reported to be associated with non-syndromic autosomal dominant congenital cataract(ADCC).Multiplex polymerase chain reaction(PCR)was carried out with microsatellite markers near to candidate loci related to congenital cataracts.PCR products from each DNA sample were separated on a 6% polyarcylamide gel and analyzed.Exclusion analysis was performed by allele sharing analysis and gene sequencing.Results The clinical phenotype in the family was isolated corroborating autosomal dominant congenital lamellar cataract.No mutation was found in the eighteen genes in all twenty-eight subjects.Eighteen candidate genes were excluded by allele sharing method and gene sequencing.Conclusion All known ADCC loci have been excluded from this family,which further indicates the clinical and genetical heterogeneity of congenital cataract,and an important clue is provided for finding more cataract responsible genes.Further study should be carried out to screen other relevant genes or loci in patients with ADCC.
