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

Prostate cancer is one of the common malignant tumors of the urinary system and mostly found in elderly men. Like most tumors, prostate cancer involves a variety of molecules in its occurrence and progression. More studies on the development of prostate cancer focus on the tumor markers, DNA damage repair related genes, and tumor invasion and metastasis related factors. This article presents an overview on the research progress in these three aspects.

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.
