Objective To observe the clinical effect of HuaYu TongFu KaiQiaoFang on serum homocysteine (Hcy)in patients with acute cerebral infarction. Methods Sixty cases of acute cerebral infarction admitted into the comprehensive ward and intensive care unit(ICU)of the First Affiliated Hospital of Guiyang College of Traditional Chinese Medicine from December 2010 to January 2012 were randomly divided into two groups,each group including 30 cases. The control group was given conventional treatment,and based on the conventional therapy,the treatment group was additionally given HuaYu TongFu KaiQiaoFang(a traditional Chinese medicine decoction including the following ingredients:Safflower 10 g,Chishao 10 g,Chuanxiong 10 g,Notoginseng 10 g,Angelica Sinensis 10 g, Shichangpu 10 g,Polygalae 10 g,Glauber's salt 5 g,Rhubarb 6 g),one dose a day by oral or nasal administration for consecutive 14 days. Before and after treatment in the two groups,the serum Hcy level was detected by enzyme-linked immunosorbent assay(ELISA),and the clinical efficacy was assessed by Pearson or Spearman correlation analysis to observe the correlation between neurological deficit score(NDS)and Hcy levels. Results Before treatment, the difference of serum Hcy(μmol/L)and NDS levels between the two groups was not statistically significant(both P>0.05),while after treatment,the levels in the two groups were significantly decreased in comparison with those before treatment(P<0.05 or P<0.01),and the degree of descent in treatment group was more obvious compared with that in control group(Hcy:7.78±2.51 vs. 10.18±2.41,NDS:10.60±2.25 vs. 14.60±3.70,both P<0.05). After treatment,the total effective rate in the treatment group was significantly higher than that in the control group (90.0%vs. 76.7%,P<0.05). Before treatment,the NDS was positively correlated with Hcy(r=0.675,P<0.05). Conclusion HuaYu TongFu KaiQiaoFang can significantly reduce the level of serum Hcy and improve the nerve function,thus its clinical effect for treatment of acute cerebral infarction is remarkable.

OBJECTIVE:To investigate the utilization of antineoplastic drugs in our hospital. METHODS:A retrospective analysis was conducted on antineoplastics used during 2005-2007 in our hospital in respect of the consumption sum,DDDs and average daily cost etc. RESULTS:Over the 3 years,the proportion of antineoplastics showed a year-on-year increase in consumption sum,with the antitumor plant amedica topping the consumption sum list and Tamoxifen topping the DDDs list for three years. Domestic drugs,injections and drugs on the RDL (reimbursable drugs list for basic medical insurance) showed high DDDs in our hospital. CONCLUSION:The consumption of antineoplastics is basically rational in our hospital,yet its management remains to be further tightened.

Objective To study the clinical features of diagnosis and treatment in children with low-risk myelodysplastic syndrome(MDS) and improve the diagnosis and treatment.Methods The examinations of 17 children with low-risk MDS were analyzed.The blood concentrations of cyclosporine,one of the therapeutic drugs,were monitored and the responses to the treatments were evaluated.Results Exa-mination of full blood count showed that the reductions of 3 cell types,2 cell types and 1 cell type were 11 (64.7%)cases,5(29.4%)cases and 1(5.9%)case,respectively.Reticulocyte count showed an increase in 82.4% of the patients and normal in 3 cases.Fourteen in 17 cases were hyperplastic marrow and 3 cases were hypoplastic marrow.Among all cases,one lineage,2 lineages and 3 lineages dyspoiesis were seen in 8(47.1%),7(41.2%) and 1 (5.9%)cases,respectively.One case showed no dyspoiesis.Cytogenetics examination showed normal in 10(58.8%) cases and abnormal in 7(41.2%) cases.Fifteen (88.2%) cases had normal proportions of CD59 negative cells,while 2 cases had higher proportions.The blood concentrations of cyclosporine that were tested in 9 cases at the end of the third week were in a range of 95.3-316.5 ?g/L.The therapeutic effect of 10 cases were evaluated at the end of the third month after being treated.Eight cases achieved haematological improvement and 2 cases didn′t.The rate of improvement was 80%.Conclusions The patients of low-risk MDS are mostly school-aged children and pancytopenia is the most common sign.The combination of predisone,cyclosporine and stanozolol agents shows good effect to treat low-risk MDS.The absorption of cyclosporine is different individually,so it is significant to adjust the dosage of cyclosporine according to the concentration regularly in clinical practice.

Objective To explore the clinical features and prognosis of arrhythmia in newborn infants.Methods Eighty children with arrhythmia were diagnosed by physical examination and electrocardiogram monitoring in author's hospital from Jan.2004 to Dec.2006.Their clinical features and 24-hour dynamic electrocardiogram were analyzed at the acute stage and followed up.Results Out of 80 cases of arrhythimics,52 cases were boys and 28 cases were girls,with an average age of 4 days on diagnosis of arrhythmias.Forty-five neonates presented with supraventricular arrhythmia,accounting for 56.3%.Their clinical presentations were atypical,and the hypoxia,infection,electrolyte disturbances and metabolic disorders were the main causes of the arrhythmias.After supportive and anti-arrhythmia treatment,18 cases of arrhythmias disappeared of 25 children with premature atrial beats;10 cases of 21 children with premature ventricular beats were cured,2 cases of 4 children with ventricular tachycardia,1 case died;2 cases of 3 children with supraventricular tachycardia didn't occure;3 cases of 5 with atrio-ventricular block were cured.The prognosis was better in supraventricular arrhythmias than that in ventricular and other arrhythmias at discharge.At the follow-up of(1.2?0.7)years,there were no differences in rates of recovery between supraventricular arrhythmias and ventricular arrhythmias.Conclusions Supraventricular arrhythmia was the most common type of arrhythmias in neonates.Most of the arrhythmia in neonates might be functional and could recover without treatment.Supraventricular arrhythmia usually had better prognosis in acute period.Only a few neonates with severe arrhythmia need anti-arrhythmias treatment.

This study was designed to determine the effects of the recombinant adeno-associated virus vector containing sense CD151 gene (rAAV-CD151) and antisense CD151 gene (rAAV-antiCD151) on the migration of Tca8113 cell. Functional fragment of CD151 gene was amplified by RT-PCR, and inserted into the vector pAAV in the sense direction and antisense direction, respectively. The rAAV-CD151 and rAAV-antiCD151 were produced and the titers were determined by dot blot. The CD151, at protein level, was detected by Western blot. The Transwell chamber was used to detect the effects of the rAAV-CD151 and rAAV-antiCD151 on the tumor cell migration. The titers of the rAAV-CD151 and rAAV-antiCD151 were 2 x 10(11) pfu/ml and 1.0 x 10(11) pfu/ml, respectively. The expression of CD151 was increased by 108% in the cells transfected with rAAV-CD151 and decreased by 79% in the cells transfected with rAAV-antiCD151, as compared with non-transfected cells, respectively. The number of the migrating cells was significantly increased in the cells transfected with rAAV-CD151 (93.56 +/- 11.59) and decreased in the cells transfected with rAAV-antiCD151 (24.00 +/- 4.36) as compared with non-transfected and rAAV-GFP transfected cells (53.00 +/- 6.56 and 46.00 +/- 7.00, P<0.05). It is an important molecular mechanism of the tumor metastasis that the overexpression of CD151 promotes the migration of the tumor cells. The rAAV-antiCD151 is a novel tool, which can reduce the expression of CD151 and inhibit the migration of the tumor cells, and brings us a new approach of anti-sene gene therapy targeted at CD151 in human carcinoma.

OBJECTIVE: To investigate the efficacy of combined medical treatment on auditory neuropathy spectrum disorder and the effect of related factors on the prognosis. METHOD: Eleven cases (22 ears) diagnosed as auditory neuropathy spectrum disorder using multiple criteria including pure tone auditory threshold, impedance audiometry, acoustic reflexes, distortion products otoacoustic emission (DPOAE) and auditory brainstem response (ABR) were subjected to combined medical treatment . Eleven auditory neuropathy spectrum disorder patients diagnosed during the corresponding period but refused treatment were selected as control group. The change of pure tone auditory threshold and speech discrimination score after treatment or follow-up were evaluated for both 2 groups, and the relationship between the patients' gender, age, accompanying symptoms and curative effect were also analyzed. Data were analyzed by SPSS 19.0 statistical software using pared-sample t-test, independent-sample test and Pearson's chi-square test. RESULT: The effective rate of combined medical therapy was 59.09% (13/22) in the therapy group. PTA levels before and after-treatment were (53.92 +/- 18.86) dB HL and (47.44 +/- 14.98) dB HL respectively in 22 ears with the combined medical therapy, the improvement of which showed statistically significance (t = 5.20, P < 0.05). No obvious hearing change was noted in the 11 patients who refused therapy (P > 0.05). Speech discrimination score before and after-treatment were (29.20 +/- 25.80)% and (41.60 +/- 22.90)% respectively for the treatment group. The average improvement of speech discrimination score was (12.40 +/- 13.80)% with statistically significant difference (t = 4.02, P < 0.05). Patients accompanied with tinnitus had relatively poorer effect compared with individuals without tinnitus (t = -3.85, P < 0.05). Age is negatively correlated with the prognosis (r = -6.72, P < 0.05). Gender had no effect on the prognosis (P > 0.05). CONCLUSION The combined medical therapy with glucocorticoids helps improving the pure tone auditory threshold and speech discrimination score of auditory neuropathy spectrum disorder. In light of our findings we support the combined medical therapy as an option for patients with auditory neuropathy spectrum disorder.
