AIM To explore the effects and mechanism of cobra venom serum on the proliferation in HL60 cells. METHODS Established the HL60 cells as a target to study the growth feature by the action of cobra venom serum.The agarose gel electrophoresis and flow cytometry analysis were used to demonstrate apoptosis. RESULTS Compared with the control group, the cells were inhibited significantly by the action of cobra venom serum.A characteristic DNA "ladder" was detected by using agarose gel electrophoresis. By flow cytometry analysis,it was proved that most apoptosis of HL60 cells occurred when cultured with cobra venom serum. CONCLUSION Cobra venom serum inhibited the HL60 cells in vitro , which was related to apoptosis. This may introduce a new way to the treatment of leukemia.

Objective To investigate the compound donkey-hide gelatin syrup in reducing adverse reactions of qi-blood weakness patients caused by clozapine.Methods 132 patients from Psychiatric Hospital of Yunnan Province between January 2010 and June 2010 were randomly divided into a treatment group and a control group.Both groups were taken clozapine orally.On this basis,the treatment group was taken compound donkey-hide gelatin syrup and the control group was taken placebo syrup.After 8 weeks treatment for both groups,the PANSS,TESS,physical examination and experiment examination were observed to evaluate the clinical efficacy and safety.Results ① the total curative effect:the treatment group was 73.53％,the control group was 65.63％,showing statistical difference (x2=2.543,P＜0.05).② PANSS scores changes before and after the treatment:PANSS score at 2,4,6,8 weeks after the treatment of both groups were [(72.51 ±27.55),(60.54±24.03),(53.12± 15.27),(48.15± 11.88) in treatment group respectively,and (70.71 ±23.90),(58.89± 18.95),(53.06± 14.38),(48.98 ± 9.78) in the control group,respectively],both showing significant difference than the same group before the treatment [(103.99±39.12) in the treatment group,(99.78±34.35) in the control group] (P＜0.05).But there was no statistical significance between two groups (F=2.413,P＞0.05).③ adverse reactions:during the treatment liver function,blood cell analysis,dystonia,Parkinson's obstacle,akathisia,abnormal gastrointestinal reaction,heart rate,heart rate variability and blood pressure in the treatment group was significantly lower than the control group (x2=4.562,P＜0.05).Conclusion Compound donkey-hide gelatin syrup can effectively relieve adverse reactions in qi-blood weak psychosis patients after clozapine treatment and improve their drug tolerance.

ObjectivesTo investigate the clinical value of the melting curve analysis-based PCR assay for the clinical genetic diagnosis and prenatal diagnosis of β-thalassemia.Methods A total of 451 peripheral blood samples,including 372 cases with β-thalassemia phenotypes and 79 cases without β-thalassemia phenotypes,were collected by Liuzhou Municipal Maternity and Child Healthcare Hospital between January 2011 and August 2011.Moreover,another 84 cases,including 16 fetal villi samples (10 - 13 weeks),64 amniotic fluid samples (16 -24 weeks ) and 4 umbilical cord blood samples (above 17 weeks),whose parents were β-thalassemia carriers,were also collected for this assay between June 2011 and September 2011.A double-blind test was done to compare the detection reliability of the melting curve analysis-based assay (24 β-thalassemia mutations can be detected) with PCR-RDB probe assay (17 β-thalassemia mutations can be detected ) and DNA sequencing using these samples.The wildtype,mutant and total concordance rates of the genotyping results were calculated separately among the melting curve analysis based assay,PCR-RDB probe assay and DNA sequencing.Results Among the 451 peripheral blood samples,thirteen mutations and nineteen genotypes were obtained by using melting curve analysis-based assay.447 samples had the same detection results and 4 samples had different detection results by comparing melting curve analysis-based assay with PCR-RDB probe assay,thus,the concordance rate of the sample detection result was 99.1％ (447/451),and the concordance rate of the allele detection result was 99.6％ (898/902).DNA sequencing results of the 4 samples showed that 3 samples had the same genotyping result with melting curve analysis-based assay,and 1 sample had the same genotyping result with PCR-RDB probe assay.A rare β-globin mutation which was not included by melting curve analysis-based assay was not detected.Thus,the genotypes of 450 samples were detected accurately by melting curve analysis-based assay,and the concordance rate of the sample detection between the melting curve assay and DNA sequencing assay was 99.8％ (450/451).Among 84 fetal villi,amniotic fluid,and umbilical cord blood samples,8 mutation types and 18 genotypes were obtained by using melting curve analysis-based assay.All the samples have the same detection results by comparing melting curve analysis-based assay with PCR-RDB probe assay and DNA sequencing,so the concordance rate of the genotyping results was 100％ among the melting curve analysis-based assay,PCR-RDB probe assay and DNA sequencing.Conclusions The melting curve analysis-based PCR assay can detect multiple unknown samples simultaneously,and detect multiple mutations accurately.It is very useful for the genetic diagnosis and prenatal diagnosis of β-thalassemia.

2 years),seizure frequency(≥1 time/month),persistence time(≥60 s),gene-ralized seizure were all associated with the incidence of the loss of neuron in ammonias.Multivariate Logistic regression analysis showed that the independent influencital factors for the loss of neuron in ammonias in children with temporal epilepsy included seizure frequency,persis-tence time and tape of seizure. Conclusions The loss of neuron in ammonias though 1H-MRS can be detected.The results of multivariate analysis verify that the development of the loss of neuron in ammonias may be associated with many factors including age of onset,course of di-sease,seizure frequency,persistence time and generalized seizure.In order to lower the incidence of the loss of neuron,early intervening treatment is very important.

OBJECTIVETo explore whether daunorubicin (DNR) combined with cytosine arabinoside (Ara-C) and DNR alone have similar effect on acute promyelocytic leukemia (APL) cell line NB4 and acute myeloblastic leukemia cell line HL-60 in vitro.

METHODSCell morphology, cells viability, and cell apoptosis (Annexin-V by flow cytometry assay) were analysed.

RESULTSAfter incubation with DNR plus Ara-C for 24 hours,NB4 cell viability [(36.75 +/- 3.82)%] (n = 6) and cell apoptosis rate [(21.24 +/- 5.82)%] (n = 3) did not change significantly compared to that treated with DNR alone for 24 hours [(35.73 + 6.28 )%, (22.55 +/- 3.26)%, respectively] (P > 0.05). However, HL-60 cell viability [(67.17 +/- 2.07)%] and cell apoptosis rate [(48.05 +/- 0.92)%] changed significantly in DNR plus Ara-C group compared with DNR alone [(63.31 +/- 1.80)% ,(41.51 +/- 0.89)%, respectively] (P < 0.01 and < 0.05, respectively).

CONCLUSIONDNR plus Ara-C and DNR alone have similar effect on NB4 cells, but have different effect on HL-60 cells.

OBJECTIVETo summarize the clinical manifestation, operative method and therapeutic effect of various type of laryngeal web in infants.

METHODSThe clinical data of 12 cases were analyzed, 5 cases of which were congenital laryngeal web (4 cases, glottic type; 1 case, subglottic type), 7 cases of which were secondary laryngeal web (1 case, tuberculous laryngeal web; 6 cases, traumatic laryngeal web). Diagnosis was mainly depended on history and clinical manifestation. Final diagnosis was depended on fibrolaryngoscope and pathological report. Microlaryngoscopic surgery was the main operative method. However, specific infection should be cured before operation.

RESULTSDuring 3-18 months follow-up, 4 glottic laryngeal webs were cured. One subglottic laryngeal web case well recovered and secondary surgery is not needed at least recently. One tuberculous laryngeal web was followed up for 6 months, no vocal adhesion was observed. During 3-6 months follow-up, 1 traumatic laryngeal web was cred, while the other 6 cases need secondary surgery.

CONCLUSIONSFinal diagnosis of congenital laryngeal web is mainly depended on fibrolaryngoscope. And prognosis of it is well. Laryngeal web induced by specific infection should be cured specific infection before operation. The prevention is the key for traumatic laryngeal web because the surgery outcome is not satisfactory.

OBJECTIVETo investigate the effects of Liuweidihuang pills (LP) on visceral fat deposition in Otsuka Long-Evans Tokushima Fatty (OLETF) rats.

METHODSForty male OLETF rats were randomly divided into LP group and control group (n=20 per group), and 10 male Long-evans Tokushima Otsuka (LETO) rats were used as normal controls. The rats in LP group were given LP(2.4 mg/kg) daily by intragastric administration since the age of 8 weeks, and those in the other two groups were given water of the same volume by intragastric administration. Blood glucose of all the rats was determined by oral glucose tolerance test (OGTT) and visceral fat deposition examined after the rats were sacrificed.

RESULTSOLETF rats had obviously greater amount of visceral fat than LETO rats (P<0.05) and administration of LP ameliorated the increment of visceral fat deposition in this type 2 diabetic model, producing significant effect at the age of 40 weeks (P<0.01).

CONCLUSIONLP may effectively decrease visceral fat deposition in OLETF rats.
