A total of 154 sera from patients with nasopharyngeal carcinoma(NPC), patients with other head and neck tumors(OHNT) and healthy individuals (HI) from Shaanxi province were tested for IgA antibody to EB viral capsid antigen (VCA-IgA) by immunoenzyrnie method. 75.93% of 54 pretreated NPC patients had VCA-IgA antibody with a GMT of 1: 38. 00,whereas less than 12. 00%of 50 OHNT and 50 HI with a GMT of 1: 2. 5 ～ 1: 3. 35.The results showed that the detection of VCA-IgA was of great value in diagnosis of NPC from low risk areas. The elevated level of VCA-IgA was seen in well-differentiated squamous cell carcinoma which gave a pattern similar to that noted in vacuolar nuclear cell carcinoma or less-differentiated carcinoma, but not in undifferentiated carcinoma. The VCA-IgA positive ratio in NPC patients below 30-year-old was similar to that in OHNT, however the GMT was elevated markedly. The results above showed that VCA-IgA antibody was of little value in diagnosis of NPC below 30-year-old and undifferentiated carcinoma.

OBJECTIVETo compare the difference in the efficacy between acupuncture and oral administration of trazodone and the expressions of neurotransmitters in patients of insomnia differentiated as liver stagnation transforming into fire.

METHODSSeventy patients of insomnia differentiated as liver stagnation transforming into fire were randomized into an observation group and a control group, 35 cases in each one. In the observation group, acupuncture therapy was adopted at Shenmen (HT 7), Baihui (GV 20), Yintang (GV 29), Hegu (LI 4), Taichong (LR 3), etc. The needles were retained for 20 min each time. The treatment was given once a day, the treatment of 2 weeks made one session. In the control group, trazodone, 100 mg, oral administration, once a day, the treatment of 2 weeks made one session. Two sessions were required in the two groups. The scores in Pittsburgh sleep quality index (PSQI) and Asberg rating scale for side effects (SERS), the levels of neurotransmitters such as 5-hydroxy tryptamine (5-HT) and norepinephrine (NE) and the expressions of protein kinase C (PKC) and brain-derived neurotrophic factor (BDNF) in peripheral blood were observed before and after treatment in the two groups.

RESULTSPSQI score and SERS score after treatment were all decreased compared with those in both groups before treatment (both P<0. 05). After treatment, PSQI score and SERS score in the observation group were lower apparently than those in the control group (both P<0. 05). After treatment NE content and PKC level were decreased; 5-HT content and BDNF mRNA were increased compared with those in both groups before treatment (all P<0. 05). NE content and PKC level in the observation group were lower apparently than those in the control group (both P<0. 05). The serum 5-HT content and BDNF mRNA expression in the observation group were higher than those in the control group separately (both P<0. 05).

CONCLUSIONAcupuncture therapy improves the sleeping quality of patients of insomnia differentiated as liver stagnation transforming into fire, and reduces serum NE level and increases 5-HT content and BDNF expression, which achieves the better efficacy as compared with the oral administration of trazodone. It is one of the effective approaches to the treatment of insomnia differentiated as liver stagnation transforming into fire.

ObjectiveTo explore the value of acupuncture in treating insomnia due to stagnated liverqi transforming into fire and its theoretical foundation, by observing the treatment effect of acupuncture in treating insomnia due to stagnated liverqi transforming into fire and its influence on 5-hydroxy tryptamine (5-HT) content.MethodTotally 187patients with insomnia due to stagnated liver qi transforming into fire were selected and randomized into two groups. The 93 cases in the control group were intervened by orally taking Trazodone, 100 mg for each dose, twice a day, 10 d as a course, totallyfor 2 courses; the 94 cases in the observation group were intervened by acupuncture at Shenmen (HT7), Baihui (GV20), Yintang (GV29), Hegu (LI 4), and Taichong (LR 3), once a day, 10 d as a treatment course, totally for 2 courses. Peripheral blood was collected from the two groups before and after intervention to detect the change of 5-HT content. Meanwhile, the Pittsburgh Sleep Quality Index (PSQI), Hamilton Depression Scale (HAMD, 24-item version), Asberg Rating Scale for Side Effects (SERS), and clinicalefficacies were assessed.ResultThe difference in 5-HT content between the two groups was statistically insignificant before intervention (P>0.05); 5-HT contents were significantly increased in both groups after intervention (P<0.05), while the content in the observation group was markedly higher than that in the control group (P<0.05); after treatment, the PSQI and HAMD scores were decreasedin both groups (P<0.05), while the PSQI, HAMD, and SERS scores in the observation group were markedly lower than those in the control group (P<0.05);the total effective rate was 92.6% in the observation group, significantly higher than 81,7% in the control group (P<0.05). ConclusionAcupuncture can significantly down-regulate 5-HT content in insomnia patients, and its total effective rate is higher than that of medication.

Objective:To explore the intermedial to long term surgical management in aortic valve insufficiency(AI)after ventricular septal defect(VSD)repair.Methods:A total of 22 consecutive patients with AI after VSD repair in our hospital from January 1996 to December 2007 underwent surgical treatment were enrolled in this study. Valve perforation was mainly pathological changes. Aortic valve replacement was performed in 13 patients and aortic valvuloplasty was done in 9 patients.Results:One patient died after the operation.Post operative X-ray and echocardiogram revealed that both cardio-thoracic ratio(0.57±0.07 vs. 0.52±0.04 P<0.05)and left ventricular end diastolic diameter(54.5±10.2 mm vs. 46.7±5.8mm P<0.05)decreased markedly. 3 patients suffered from mild aortic regurgitation after valvuloplasty.Conclusion:The iatrogenic injury of aortic valve during VSD repair could be corrected satisfactorily by valve replacement or valvuloplasty.

To modify uricase with PEG reagent in order to decrease uricase immunogenieity and increase its stability.Methods:The branched PEG of 40 kD was chosen to modify native uricase.The properties of the mod-ified uricase including the stabilities to protease,pH and temperature,in vivo half-life time,as well as the immu-nogenicity were evaluated.The pharmacokinetic profiles of the midofied uricase were studied in mice.Results:It is demonstrated that the conjugation of PEG to lysine residues of Candida utilis uricase resulted in higher tryp-sin resistance.reduced immune response.and prolonged in vivo half-life.PEG modified uricase retained 80% of the enzymatic activity of native uricase.In addition,it was found that half-life in serum of the intravenously injec-ted PEGylated uriease of up to 696 min was longer that that of native uficase of 45 min.Higher plasma drug con-centrations were also reached with dosing of the PEGylated uricase to mice.Furthermore,the binding affinity Was shown to be reduced for the PEG-uricase using ELISA assay.and it was one-eishth that of native uricase.Final-ly,it Was indicated that the PEG uficase induced a delayed immunoresponse in mice following repeated adminis-trations.Conclusion:These findings demonstrate that this chemically modified form of uricase may serve as a potentially effective drug to treat gout patients.
