?AlM:To study the relationship between blood lead level and abnormal eye blinking in children.
? METHODS: The patients with chief complaint of frequent eye blinking, whose diagnosis of abnormal eye blinking, were randomized to experimental group. The patients in this group carried out vision and the slit-lamp examination, detected corneal fluorescein staining and tear break-up time, and improved the level of blood lead and trace elements examination. The patients in control group with chief complaint of health physical examination in our hospital, excepted of blood lead level, the other body check results were normal and were divided into boys group and girls group according to the gender. The changes of the experimental group and control group in blood lead level were compared.
?RESULTS: Totally 371 cases ( male:295 cases; female:76 cases) with mean age was 6. 56±2. 41 years and 6. 08±2. 82 years respectively were in experimental groupe. ln control group, there were 300 cases ( male: 186 cases;female:114 cases) with mean age was 6. 99±3. 01 years and 6. 56±2. 80 years respectively. The average of blood lead level of boys in experimental group was 63. 82 ±24. 56μg/L and 53. 98±15. 42μg/L in control group. The average of blood lead level in experimental group was higher than that in control group. The difference between of the two group was statistically significant (χ2=16. 96, P<0. 01 ). The average of blood lead level of girls in experimental group was 56. 96±16. 69μg/L and 48. 18±12. 35μg/L in control group. There was no difference between of the two group (χ2=5. 77, P=0. 56). ln control group, the average of blood lead level with <3 years, 3~6 years and >6 years children were 48. 73±11. 67μg/L, 51. 39 ± 14. 87μg/L, 52. 98 ± 14. 45μg/L respectively. ln expirement group, the results were 56. 57±17. 89μg/L, 59. 92±18. 46μg/L and 67. 00±32. 55μg/L in <3, 3~6 and >6 children, respectively. There was no significant difference with <3 years (χ2=3. 54, P=0. 17). The difference with 3~6 years and >6 years children were statistically significant (χ2 = 9. 62, P = 0. 008 ) and (χ2 = 19. 22, P = 0. 000 ) respectively. The blood lead level were divided into three grades: <50μg/L, 50 ~100μg/L, >100μg/L, and relative risk (RR) were 0. 65, 1. 22, and 10. 11 respectively.
?CONCLUSlON: Blood lead level of experimental group is higher than that of control group. The relationship between blood lead level and abnormal eye blinking in children is positive correlation.

Objective To investigate the effects of ischemic postconditioning (Post) on myocardial cell apoptosis and expres- sion of Bcl-2 and Bax protein during ischemia/reperfusion period in rabbits.Methods Eighteen rabbits were randomly allocated to three groups (6 in each group),sham operation (group S),ischemia/reperfusion group(group IR) and ischemic postconditioning group(group Post).Group IR and group Post were subjected to 15 minutes of left anterior descending coronary artery occlusion followed for 30 minutes of reperfusion.Ischemic postconditioning was achieved by three 30 seconds cycles of reperfusion,each followed by 30 seconds ischemia.Cardiomyocyte apoptosis were determined by in situ TDT-mediated dUTP nick end labeling (TUNEL) and DNA electrophoresis.The expression of Bcl-2 and Bax proteins in apoptotic myocardial cells were detected by immunohistochemistry sepa- rately.Results Compared with group IR,apoptotic index was significantly reduced in group Post [(28.06?2.92) % vs.(55.70? 13.96)%,P

Objective To demonstrate the carbonic anhydrase Ⅲ (CAⅢ) for 25 000 protein decreased in skeletal muscle of myasthenia gravis (MG). Methods The protein molecular properties responsible to antibodies against 25 000 protein and CAⅢ were analyzed by a combination method of two-dimensional electrophoresis and immuno-Western blot. Competitive binding reactions of the antibodies to the purified 25 000 protein and muscular homogenate were observed by using immuno-Dot blot and immuno-Western blot, respectively. The expression of CAⅢ from normal and MG muscles was detected by immuno-Western blot. Results Combination analysis of two-dimensional electrophoresis and immuno-Western blot showed that the protein of immunological responsible to antibodies against 25 000 protein and CAⅢ had an identical molecular mass and isoelectric point. Competitive binding reactions proved that 25 000 protein and CAⅢ were the same substance, either by immuno-Dot blot or by immuno-Western blot. In addition, a much similar result was obtained when the levels of 25 000 protein from normal and MG muscles were detected by antibodies against 25 000 protein and (CAⅢ) by immuno-Western blot. Conclusion 25 000 protein decreased in the MG skeletal muscle was proved to be just a known protein CAⅢ, which made a basis for further exploring the relationship of CAⅢ deficiency and MG pathogenesis.

OBJECTIVETo explore the classification basis of functional dyspepsia in disease menu of acupuncture, and to provide regular analyzing process for classification of other diseases.

METHODSTaking the control group as the classification basis, and the 5-level literature classification of evidence based medicine as the estimation basis, literatures which complied with the inclusion criteria were examined according to the sequence from high level to low. Evidences of low levels were given up if support can be acquired from documents of high level.

RESULTSAcupuncture is approved to be effective for intervention on functional dyspepsia. Compared to the international accepted medicines such as Cisapride and Motilium, regular acupuncture has better therapeutic effects and less side effects in improving the gastro-power and relieving discomfort sensations.

CONCLUSIONFunctional dyspepsia pertains to grade I of disease menu of acupuncture.

OBJECTIVETo evaluate the impact of hand video-assisted thoracoscopic surgery (HVATS) and Ivor-Lewis surgery on short term quality of life (QL) of patients with esophageal cancer.

METHODSThirty-nine consecutive patients with esophageal cancer were classified into HVATS group (n = 21) and Ivor-Lewis group (n = 18) randomly, all patients completed the Chinese versions of the European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire (QLQ)-C30 and QLQ-OES18 before treatment and at regular intervals until 6 months after operation. MEAN scores were calculated for every patient.

RESULTSBaseline functional and symptom QL MEAN scores were similar in both groups. All patients reported worse functional, symptom and global QL scores (QOL) within 6 months after operation than before. HVATS group gained higher functional, global QL scores and lower symptom scores than Ivor-Lewis group, moreover, patients' QL scores of HVATS group returned to preoperative levels more quickly than those patients in Ivor-Lewis group. Significant differences were found in global health (QOL), physical functioning, fatigue and pain scales between groups. In both groups, QLQ-OES18 dysphagia scales were improved after surgery,but no significant differences were found at scales respect to esophageal cancer.

CONCLUSIONSHVATS esophagectomy is a safe procedure which has a low disturbance to patients' short term Quality of Life compared with Ivor-Lewis esophagectomy. It might seem reasonable to choose HVATS esophagectomy for patients with early stage esophageal cancer.

OBJECTIVETo investigate the cell-killing effect of adenovirus-mediated TK-ganciclovir (GCV) gene therapy in combination with tumor necrosis factor-alpha (TNF-alpha) against murine bladder carcinoma cells in vitro.

METHODSMurine bladder carcinoma MB49 cells were transfected with the adenoviral vector containing TK gene and green fluorescent protein (GFP) gene. The transfection efficiency was observed and the TK gene expression in the transfected cells was detected by RT-PCR. The survival rate of MB49 cells in response to TNF-alpha treatment and that of the TK gene-transfected cells after treatment with GCV and GCV+TNF-alpha were determined by MTT assay. The apoptosis of the cells after the treatments was analyzed by flow cytometry.

RESULTSIn cells transfected with TK gene, the cell inhibition rate increased gradually with the increment of GCV and TNF-alpha concentration. GCV in combination with TNF-alpha resulted in significantly increased killing efficiency of the cells as compared with GCV or TNF-alpha treatment alone, and the effect of the combined treatment was enhanced as the TNF-alpha concentration increased. GCV treatment (50 microg/ml) alone produced a cell killing rate of (24.39-/+1.10)%, and when combined with 5 microg/ml TNF-alpha, the rate was increased to (40.05-/+0.97) %, and further to (65.47-/+0.67) % when TNF-alpha concentration increased to 20 microg/ml. Flow cytometry revealed obvious apoptosis of the cells 8 h after treatments with TK/GCV, TNF-alpha, or TK/GCV+TNF-alpha, and the combined treatment resulted in the highest cell apoptotic rate.

CONCLUSIONTK/GCV in combination with TNF-alpha can enhance the effect of suicide gene therapy against murine bladder carcinoma cells and effectively induce apoptosis of the cells.
