OBJECTIVE:To systematically review the efficacy and safety of the Bushen huoxue lishi category TCM compound in the treatment of chronic prostatitis,and provide evidence-based reference for clinical treatment. METHODS:Retrieved from VIP Database,Wanfang Database,CJFD and CBM,randomized controlled trials(RCT)about Bushen huoxue lishi category TCM com-pound preparation (test group) versus conventional Western medicine (control group) in the treatment of chronic prostatitis were collected. Meta-analysis was performed by Rev Man 5.3 software after data extraction and quality evaluation. RESULTS:Totally 22 RCTs were enrolled,involving 1 863 patients. Results of Meta-analysis showed the total effective rate [OR=4.46,95%CI(3.40, 5.84),P<0.001],total scores of chronic prostatitis symptoms[MD=-3.62,95%CI(-5.21,-2.04),P<0.001] and lecithin count [MD=7.58,95%CI(2.15,13.01),P=0.006] in test group were significantly higher than control group,prostatic fluid white blood cell count [MD=-1.68,95%CI(-3.26,-0.10),P=0.04] was significantly lower than control group,with significant differenc-es. CONCLUSIONS:Bushen huoxue lishi category TCM compound has good efficacy in the treatment of chronic prostatitis.

Objective To investigate the clinical application of various parameters of visual evoked potential (VEP) and auditory evoked potential (AEP) in patients with attention deficit and hyperactive disorder (ADHD), mental retardation (MR) and conduct disorder (CD). Methods Thirty-seven ADHD patients, 24 MR patients, 22 CD patients and 36 normal subjects were included in this study. The VEP and AEP were recorded from every subject and analyzed. Results A significant difference was found among 4 subject groups, with both latencies (Oz/N_1, P_2) and amplitudes of VEP (Cz/P_2, P_3 and Oz/P_3 ) (P

Objective To investigate the features of brainstem auditoryresponses (BAR) in patients with attention deficit and hyperactive disorder (ADHD), mental retardation and conduct disorder. Methods BAR in children with ADHD ( n =37), mental retardation (MR, n =24) and conduct disorder (CD, n =22), and in normal children ( n =30) were measured by use of Nicolet Spirit electrophysiological instrument delivering stimulation of Clicks. Results The absolute latencies (AL) of wave Ⅲ、Ⅴ recorded from Fz region (WⅢ、Ⅴ/Fz) and wave Ⅲ from Pz region (WⅢ/Pz) as well as the absolute amplitudes (AA) of WⅢ/Fz and WⅤ/Pz were significantly different ( P

Objective The effect of different doses of ethylnitrosourea(ENU)and cyclophosphamide(CP)on the loss rate of CD59 on peripheral blood erythrocytes was explored to optimize the detection method of Pig-a gene mutation. Methods According to the weight and loss rate of CD59 on peripheral blood erythrocytes,rats were divided into 4 groups:the control group,CP 40 mg/kg group,ENU 10 mg/kg group and ENU 40 mg/kg group(n=6). The control group was injected i.p. with PBS,other groups were injected i.p. with corresponding solutions. The body weight of rats on days 0,7,14,21, 28, 42 and 56 were recorded. At the same time, blood samples were collected and incubated with antibodies,and the loss rate of RBCCD59-was detected by flow cytometry. Results Compared with the control group, at different time points, the body weight and weight gain of ENU 10 mg/kg group and ENU 40 mg/kg group had no statistically significant difference(P > 0.05),while those in the CP 40 mg/kg group were significantly decreased(P <0.05). The loss rate of RBCCD59-was significantly increased in the CP 40 mg/kg group at 28,42 and 56 days, ENU 10 mg/kg group at 42 and 56 days,and ENU 40 mg/kg group at 7,14,21,28,42 and 56 days,(P < 0.05). The results showed a dose-response relationship. Conclusions Under the conditions of this Pig-a mutation detection method,ENU is superior to CP on raising loss rate of RBCCD59-,ENU 40 mg/kg is better than 10 mg/kg,and 28 days is suitable as the test period.

OBJECTIVETo study the clinical characteristics, antibiotics sensitivity and outcome of group B streptococcus (GBS) meningitis in neonates in order to provide the guide for early diagnosis and appropriate treatment.

METHODA retrospective review was performed and a total of 13 cases of neonatal purulent meningitis caused by GBS were identified in the Neonatal Intensive Care Unit of Yuying Children's Hospital of Wenzhou Medical University from January 1, 2005 to May 31, 2013. The clinical characteristics, antibiotics sensitivity test results and outcome were analyzed.

RESULTFever, poor feeding, seizure and lethargy were common clinical signs of neonatal purulent meningitis caused by GBS. Three cases of early onset GBS meningitis received prepartum antibiotics. All 13 cases had abnormal C-reactive protein (CRP) level, and 11 cases had increased CRP within hours after admission. Of the 13 patients, 7 were cured, 4 discharged with improvement, 2 patients died during hospitalization after being given up because of serious complication. The average length of stay for recovered patients was (47 ± 21)d. Acute complications mainly included hyponatremia (5 cases), intracranial hemorrhage (3 cases) , ventriculomegaly (3 cases) , subdural collection (2 cases) , hydrocephalus (2 cases), septic shock (2 cases), cerebral hernia (1 case), encephalomalacia (1 case). One preterm patient with early onset GBS meningitis died 1 month after hospital discharge. Among 7 survivors with 10-24 months follow-up, 3 were early onset GBS meningitis, 2 with normal results of neurologic examination, 1 with delayed motor development, 4 were late onset GBS meningitis, 1 with normal results of neurologic examination, 3 were neurologically impaired with manifestations including delayed motor development (2 cases) and seizures (1 case). All the GBS strains were sensitive to penicillin and linezolid (13/13, 10/10), the susceptibility to levofloxacin, ampicillin and vancomycin were 11/12, 9/10, 8/13 respectively.

CONCLUSIONThe clinical manifestations of neonatal purulent meningitis caused by GBS are usually non-specific. It is associated with long hospitalization, neurological impairments and sequelae. Monitoring of serum CRP level is valuable for early diagnosis. Antepartum prophylaxis, early diagnosis and therapy are vital. Large dose penicillin is the priority choice to treat the neonatal purulent meningitis caused by GBS, linezolid should be used in intractable cases.
