Objective To assess the effect of ambient air SO2 on mortality of respiratory diseases. Methods Based on the ecological theory, after the adjustment of seasons, temperature, humidity and air pressure, the observed individuals were divided into eight groups. The association between SO2 exposure and mortality rate of respiratory diseases was analyzed using Poisson regression and local auto-regression method. Results SO2 concentration increased by 0.05 mg/m3, the mortality of respiratory diseases increased by 5.90% (95%CI: 2.26%-9.68%) in all groups, in children by 10.23% (95%CI: 2.07%-19.04%), in young-middle-male group by 1.10% (95%CI: -9.51%-12.96%), in young female group by 9.58% (95%CI: -2.57%-23.23%), in young group by 10.23% (95%CI: 2.07%-19.04%), in aged male group by 5.26%(95%CI: 0.01%-10.78%), in aged female group by 8.07% (95%CI: 3.45%-12.89%) and in aged group by 4.66% (95%CI: 1.44%-7.99%) respectively. Conclusion SO2 exposure is found to be associated with the increase of mortality of respiratory diseases, especially in children, aged people and elderly females.

Objective To analyze the relationship between the clinical features of hepatoblastoma and serum alpha-fetoprotein level.Methods We did a retrospective study in 74 cases into the relationship of clinical stages,treatment,prognosis,and AFP value in hepatoblastoma.Results In Stage Ⅰ and Ⅱ patients,the average AFP was (36 333 ± 13 782) ng/ml and in Stage Ⅲ and Ⅳ,the average AFP was (78 346 ± 27 956) ng/ml,P ＜ 0.05.68 patients received preoperative chemotherapy with alpha-fetoprotein determinations before and after chemotherapy respectively.In 44 cases AFP decreased ＞ 50％ after chemotherapy,and in 20 cases AFP declined ＞90％,while in 13 cases AFP increased after chemotherapy.15 cases had serum AFP measured on the first postoperative day,among them 10 cases had a ＞ 50％ AFP decline,3 cases had a ＜ 50％ AFP decline,while in 2 cases AFP value increased.52 cases were postoperatively followed-up,with overall 3 year-survival rate of 86.5％ ; 7 cases recurred,4 died.The average preop AFP level in 7 recurred cases was (27 060 ± 3 569) ng/ml,while the average preop AFP level in those of 3-year recurrence-free was (29 865 ± 5 867) ng/ml,P ＞ 0.05.Only 57％ tumor recurred cases had back to normal AFP level within one month postop,while 89％ long term survivals reported normal range of AFP during that period,P ＜ 0.05.Conclusions Serum AFP level in patients with hepatoblastoma is related to the course of disease.It can be used to estimate the effect of clinical chemotherapy.The speed of alpha-fetoprotein decline postop can be used as an indicator of prognosis.The postoperative normal AFP level within 4 weeks predicts a favorable prognosis.

OBJECTIVE:To observe clinical efficacy and safety of Mailuoning injection combined with benazepril in the treat-ment of chronic glomerulonephritis. METHODS:130 patients with chronic glomerulonephritis were randomly divided into observa-tion group and control group,with 65 cases in each group. Both groups received rountine treatment as low salt and fat diet. Control group was additionally given Benazepril tablet 10 mg,qd;observation group was additionally given Mailuoning injection 20 ml added into 5% Sodium chloride injection 250 ml,ivgtt,qd,on the basis of control group,20 days of drug withdrawal every 10 days. Both group received 4 months of treatment. Clinical efficacy of 2 groups were observed as well as the levels of BUN,UCr, SCr and 24 h urine protein quantitative (UPE) before and after the treatment. The incidence of ADR was compared between 2 groups. RESULTS:Total effective rate of observation group was 83.1%,which was significantly higher than 67.7% of control group,with statistical significance (P<0.05). There was no statistical significance in BUN,UCr,SCr and 24 h UPE between 2 groups before treatment (P>0.05);those indexes of 2 groups decreased significantly after treatment,and the observation group were lower than the control group,with statistical significance(P<0.05). There was no statistical significance in the incidence of ADR between 2 groups (P>0.05). CONCLUSIONS:Mailuoning injection combined with benazepril is effective for chronic glo-merulonephritis,and can effectively improve renal function with good safety.

Objective To study the effect of traditional Chinese medicine on survival time in children solid tumors with chemotherapy. Methods 76 children with solid tumors, which were collected from January 2005 to March 2006, were randomly divided into treatment group (35 cases), control group (41 cases). The treatment group was treated with chemotherapy + self-dispensing Fuzheng Jianpi Chinese medicine. The control group was treated with chemotherapy alone. Results The survival rate of the treatment group was higher than that of the control group, the difference was statistically significant (P = 0.0024). The average survival time after chemotherapy in the treatment group was (31± 2) months (95 % CI 27-34 months), the control group was (21±2) months (95 % CI 16-25 months), which was shorter than the treatment group.Conclusion Chinese medicine and chemotherapy can prolong the survival time of children with solid tumors.

Hemostatic materials are essential for the treatment of trauma patients with massive blood loss in battlefields and disaster environments. According to the site and severity of trauma, different types of hemostatic materials need to be used to stop bleeding urgently. At present, first-aid hemostatic materials for bleeding on body surface wounds, extremities and junctions have been well applied. However, in the case of deep bleeding wounds in the thoracic and abdominal cavity and internal organs and even non-compressible hemostasis, there are still no ideal hemostatic materials in early emergency treatment. In this review, the authors elaborate the classification and mechanism of hemostatic materials and their application in trauma first aid, so as to provide references for the use of hemostatic materials in first aid.

OBJECTIVES: The Tinnitus Handicap Inventory (THI) is a commonly used self-reporting tinnitus questionnaire. We undertook this study to determine the reliability and validity of the Chinese-Mandarin version of the Tinnitus Handicap Inventory (THI-CM) for measuring tinnitus-related handicaps. METHODS: We tested the test-retest reliability, internal reliability, and construct validity of the THI-CM. Two-hundred patients seeking treatment for primary or secondary tinnitus in Southwest China were asked to complete THI-CM prior to clinical evaluation. Patients were evaluated by a clinician using standard methods, and 40 patients were asked to complete THI-CM a second time 14+/-3 days after the initial interview. RESULTS: The test-retest reliability of THI-CM was high (Pearson correlation, 0.98), as was the internal reliability (Cronbach's alpha, 0.93). Factor analysis indicated that THI-CM has a unifactorial structure. CONCLUSION: The THI-CM version is reliable. The total score in THI-CM can be used to measure tinnitus-related handicaps in Mandarin-speaking populations.
