Aim To observe the effect of the polymerization of HSF1 on the febrile response in fever rabbits,and further to investigate HSF1 action in thermoregulation and the possible central mechanism.Methods 70 rabbits were divided randomly into 4 groups:the control group(N),the quercetin group(Q),the LPS-feverish group(L),the quercetin+LPS-feverish group(Q+L).Changes in body temperature were continually observed;the expression of HSF1 and HSP70 in hypothalamus was detected by Western blot;the content of AVP in hypothalamus and VSA was measured by radioimmunoassay.Results ① The sequence of the maximum change of temperature(△Tmax)from low to high:group Q

OBJECTIVE To observe the clinical efficacy of cefminox for the treatment of bacterial liver abscess. METHODS Totally 118 patients with bacterial liver abscess were treated with cefminox 2 g iv drip 12 h or 8 h for(5-10 d),then with cefminox 1 g in drip 12 h for 21-35 d. RESULTS The total cure rate was 89.4%,the overall efficacy rate was 97.6%,and side effect rate was 2.4%. CONCLUSIONS Cefminox is an effective antibiotic in treating bacterial liver abscess.

ObjectiveTo study the nurse and trentment of cerebrospinal fluid (CSF) rhinorrhea.Methods30 patients with CSF rhinorrhea who accepted surgical treatment were retrospectively analyzed.Results12 cases were traumatic CSF rhinorrhea, 17 cases were CSF rhinorrhea casused by ablation brain tumor, 1 case was pontaneous CSF rhinorrhea. First operation repaired craniosinus fistula in 23 cases, re-operation repaired in 7 cases after first operation failure. There were hydrocephalus in 1 cases, ventriculitis in 1 case, subdural effusion in 1 case.ConclusionAccurate location of the fistula and during surgical probing are important for the success of treatment, and prevention infection is very important to surgery success, and descent complication.

Objective To investigate the efficiency of levodopa in dopa responsive dystonia (DRD) patients and drugs safety in pregnancy cases confirmed by genetic detection.Methods The clinical characteristics of two patients were analyzed.Direct sequences were performed in guanosine triphosphate (GTP) cyclohydrolase Ⅰ (GCH1) gene and tyrosine hydroxylase (TH) gene mutation screening.Results Case 1 was a young man exhibiting writer's cramp and dystonia of lower legs with marked diurnal fluctuation.Writer's cramp could not be relieved by treatment of low dose levodopa/benserazide.After increasing dose,the symptom of writer's cramp appeared occasionally.Case 2 was a young woman who experienced gait disorder.The symptom disappeared completely by levodopa treatment.She used levodopa and benzhexol during pregnancy.By 38 gestational weeks,she gave birth to a healthy baby.Sequence analysis of GCH1 gene in case 1 revealed a mutation (c.230C ＞ G p.S77C) that is a novel pathogenic mutation.The confirmed mutation c.628delC (p.His210Thrfs* 5) found in case 2 had been reported previously.No mutations in TH gene were detected in two patients.Condnsions Most of DRD patients have dramatic response to levodopa,but patients exhibited writer' s cramp may respond to levodopa incompletely.The previous reports indicate that no adverse events have been reported in DRD pregnant women with the monotherapy of levodopa.

Objective To evaluate the international blood smear review criteria for improvement using Beckman-Coulter hematology analyzers and find out proper slide review criteria suitable for Chinese population. Methods 3 600 random-selected blood samples were tested in three hospitals using MAXM, GENS and LH750 5-diff automated analyzers and a manual differential with a smear review was performed on all samples in the study. True positive rate, true negative rate, false positive rate and false negative rate were calculated according to the international blood smear review criteria. We have set up smear review criteria for Chinese population by analyzing false positive and false negative cases according to Chinese clinical conditions. Another 240 blood samples were tested in three hospitals using the same analyzers to verify the new slide review rules. Results According to international blood smear criteria, the true positive rate was 4.9%, false positive rate was 24.2%, true negative rate was 70.4% and false negative rate was 0.5%. The international smear review criteria were modified into 23 criteria by analysis of above statistical data. In addition, we added four WBC differential ratio rules in positive smear criteria. After modification, the true positive rate was 9.9% (355/3 600) ,false positive rate was 17.1% (617/3 600), true negative rate was 71.2 % (2 563/3 600) and false negative rate was 1.8% (65/3 600). No blast cell was missed using both smear review criteria. A little higher false negative rate after modification was caused by supplemented differential ratio roles in positive smear criteria. Verification results were satisfactory;The tree positive rate was 13.7% (33/240) ;false positive rate was 15.8% (38/240) ;false negative rate was 2.5% (6/240) and true negative rate was 68.0% (163/240). Conclusions Although the smear review criteria suggested by the International Consensus Group is clinically important, the false positive rate increases when they are used in Chinese population. The modified slide review criteria used on Beckman-Coulter hematology analyzers in this study are more suitable for Chinese laboratories.
