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.

Objective To investigate the effect of acupuncture combined with rehabilitation on Joubert syndrome. Methods 2 infants with Joubert syndrome were reviewed. Results After the treatment of acupuncture combined with rehabilitation for 4~6 months, the clinical symptoms of these 2 cases improved, and the scores of Gross Motor Function Measure increased. Conclusion Acupuncture combined with rehabilitation is effective on Joubert syndrome.

Objective To define whether correlation exists between the enlargement of lateral ventricles and motor development delay. Methods Motor development was assessed with Peabody Developmental Motor Scale (PDMS) in 28 children with cerebral palsy. Correlation between computerized tomography (CT) findings of enlargement of lateral ventricles (ventricle index,body index,width index and frontal horn index) and motor quotients of PDMS(GMQ,FMQ and TMQ) was analyzed. Results Width index was correlated with all three motor quotients (GMQ,FMQ and TMQ)( P

Objective To study the relationships of serum neuroglobin and neuron-specific enolase level with periventricular hemorrhage-intraventricular hemorrhage ( PVH-IVH) and periventricular leucumalacia ( PVL) in preterm infants. Methods There were 241 cases of preterm infants whose gestational age was less than 34 weeks and were admitted in NICU of Guangzhou Women and Children′s Medical Center, Guangzhou Huadu District Matermal and Child Health Hospital and Dongguan Taiping Hospital from Jan. 2010 to May. 2013, enrolled in the study. The serum level of neuroglobin and neuron-specific enolase were detected within 12 hours and on the 3 d, 7 d, 14 d after birth. Cranial ultrasound was preformed 2~3 d, 1week, 2weeks, 3weeks, and 4 weeks after birth. They also received Cranial MRI examination before discharge or when the correct gestational age reached 40 weeks. All 241 cases were divided into 3 groups ( no brain damage group, PVH-IVH group and PVL group) according to the result of cranial US and MRI. The differences of the serum levels of neuroglobin and neuron-specific enolase among each groups were compared. Results The results of cranial ultrasound and /or MRI showed: 162 cases had no brain damage ( in no brain damage group) , 50 cases had PVH-IVH ( in PVH-IVH group) , and 20 cases had PVL, 9 cases had PVL and PVH-IVH ( both in PVL group) . Within 12 h and 3 d after birth, the serum levels of neuroglobin in PVL group and PVH-IVH group was significantly higher than those in no brain damage group (P<0. 05), and the serum levels of neuroglobin in PVL group were signigicantly higher than those in PVH-IVH group ( P <0. 05 ) . On 7 d and 14 d after birth, the serum levels of neuroglobin were no significant difference between PVH-IVH group and no brain damage group ( P>0. 05 ) , and there were still significantly higher than those in no brain damage group and PVH-IVH group (all P<0. 05). The serum levels of neuron-specific enolase within 12 h and 3 d after birth in PVH-IVH group and PVL group were significantly higher than those in no brain damage group ( P<0. 05 ) , and there were no significant difference between PVL group and PVH-IVH group (P>0. 05). On 7 d and 14 d after birth, the serum levels of neuron-specific enolase in PVL group were no significant difference compared with PVH-IVH group and no brain damage group (all P>0. 05). Conclusion The increased serum levels of neuroglobin and neuron-specific enolase in preterm infants within 12 h and 3 d after birth would have certain clinical significance for judging whether early brain damage and PVL would happen.

[Objective]To explore the correlation between anticardiolipin antibodies and post-SARS patients with osteonecrosis,investigate the etiology of post-SARS osteonecrosis,and select the sensitive molecular symbols for early diagnosis and distinguish the high risk population.[Method]The studied subjects were divided into two groups.Sixty-two post-SARS patients with osteonecrosis was one group,and 52 matched healthy people was as normal controlled group.Empty stomach blood samples from cubital veins were collected from both groups.IgA,IgG and IgM of anticardiolipin antibodies types were examined by ELISA.[Result]Twenty-one of 62 post-SARS osteonecrosis patients were tested at least one type of anticardiolipin antibodies positive,among them,with IgA(11.33?11.209)APL,IgG(5.127?5.927)GPL,IGM(17.821?10.606)MPL.Four of 52 control group persons were detected positive,with IGA(10.702?3.126)APL,IgG(5.184?4.780)GPL,IgM(14.684?5.516)MPL.There were significant differences between two groups,while,there were no difference in prothrombin time(PT),thrombin time(TT),prothrombin activity(PTA)and international normalized ratio(INR).[Conclusion]The study indicates an increased positive incidence of anticardiolipin antibodies in post-SARS patients with osteonecrosis.This has reflected that anticardiolipin antibodies may play a role in osteonecrosis.

Objective To investigate allele frequency distributions and haplotype polymorphism of ten Y-chromosome short tandem repeats (STR) loci of Han population in Zhuhai area and evaluate their applicability to forensic cases. Methods DYS393, DYS19, DYS389 Ⅱ, DYS390, DYS391, DYS389 Ⅰ, DYS439、DYS438、DYS392 and DYS385 loci were amplified with Y-plex~(TM) PCR amplification Kit and analyzed by ABI 310 genetic analyzer. 200 unrelated male individuals of Han nationality in Zhuhai were recruited for determination of allele frequencies and haplotype data. Results 5, 6, 6, 5, 4, 5, 5, 5, and 7 alleles were found in 9 of the 10 Y-STR loci, respectively and 44 haplotypes were detected at DYS385 locus. The range of gene diversity (GD) was determined between 0.3904 for DYS391 and 0.9497 for DYS385. Total 161 haplotypes were found at the 10 Y-STR loci, of which 134 occurred once, 20 occurred twice, 3 occurred three times, 3 occurred four times, and 1 occurred five times. The cumulative GD was 0.9948. Conclusion The 10 Y-STR loci are highly polymorphic and suitable for forensic individual identification and paternity testing in Zhuhai Han population.

OBJECTIVE To inspect and analyze the cleaning efficacy on surgical instrument after cleaning cycle and maintenance procedures.METHODS The medical instrument was collected from each department based on the weekly usages.Focus on the timing of the cleaning after use and the efficacy of the cleaning methods.Use naked eyes to inspect the cleanness of the medical instrument after each cleaning cycle.RESULTS The combination of the machine washing and manual washing immediately after the surgical procedures provided better cleaning efficacy.It was more difficult to clean the instrument once the dried bio-burden on it or after soaking in the chlorine disinfectant.CONCLUSIONS The correct cleaning methods and instrument care procedures guarantee the cleaning efficacy,disinfections,and the sterilization for the medical instrument.

Haizhenyuye(HY) is a nourishment made from fresh Stichopus japonicus Se-lecka and traditional Chinese medicine herbs. It can enhance hematopoiesical and immuologi-cal function, prevent and treat a decrease in the WBC Count caused by cyclophosphamide (CTX). Through prevention effect on rats by HY, we can prove that HY can increase the levels of WBC,Hb,PC,reticulocytes and improve hematopiesis. HY is a marine nourishment with great values.
