Objective To investigate the prevalence and the risk factors of dyslipidemia in residents aged 40 to 80 years in Guiyang. Methods A total of 10 022 adults (2 694 men and 7 328 women) aged 40 and over were selected from Yunyan community in Guiyang urban area for this population based cross-sectional study. Data were obtained by questionnaire survey, physical examination, fasting blood glucose, and lipid measurements. The association between influential factors and dyslipidemia was analyzed by logistic regression analysis. Results The standardized prevalence of dyslipidemia in residents aged 40 years and over in Guiyang was 46. 9%, with low high-densitylipoproteincholesterol(HDL-C)29.0%,hypertriglyceridemia19.3%,hightotalcholesterol(TC)9.3%, andhighlow-densitylipoproteincholesterol(LDL-C)4.3%. Logisticregressionanalysisindicatedthatage,gender, smoking, and alcohol abuse were the risk factors of high TC and high LDL-C. Abdominal obesity was a main risk factor for both hypertriglyceridemia and low HDL-C. Conclusion The prevalence of dyslipidemia of middle-aged and aged residents in urban districts of Guiyang was on the national average level. Hypertriglyceridemia and low HDL-C were the most common types. Age and abdominal obesity were important risk factors of dyslipidemia.

Objective To study the polysomnography(PSG) indexes which can reflex the severity of anoxia in obstructive sleep apnea-hypopnea syndrome(OSAHS) more comprehensively. Methods Sixtythree OSAHS patients' PSG indexes, including the apnea-hypopnea index (AHI), apnea time/total sleeping time (AM), hypoventilation time/total sleeping time (HM), mean oxygen saturation (MSaO2),the lowest oxygen saturation (LSaO2) and the longest apnea time (LAT) were analyzed retrospectively. Results In patients with OSAHS,the AHI was positively correlated with AM, HM and LAT(P < 0.01 or < 0.05 ), and was negatively correlated with MSaO2 and LSaO2(P < 0.01 ). The AHI had linear regression relationship with AM,HM and LSaO2 (F =202.264,P <0.01). Conclusions Among the PSG indexes,AM is intimately associated with AHI. Therefore,compared with LSaO2,AM and HM can reflex the severity of anoxia in patients with OSAHS more accurately.

Objective To evaluate the effect and safety of tiotropium plus sustained-release theophylline in treating stable moderate chronic obstructive pulmonary diseases (COPD) . Methods A randomized clinical trail was conducted in 80 patients with stable moderate COPD, who were admitted to our hospital from March 2008 to December 2009. All patients were divided into two groups randomly and accepted tiotropium (groupⅠ ,n =40) or tiotropium plus sustained-release theophylline (group Ⅱ ,n =40) treatment for 12 weeks. Results Seventy patients completed the study,in which 36 cases had tiotropium alone and 34 cases had combination therapy. At the end of treatment, no statistically significant difference was found between the two groups in the comparisons of FEV1, FEV1%, FVC, FEV1/FVC, activity score and impacts score of the St George's Respiratory Questionnaire (SGRQ) (Ps > 0. 05). While the symptoms score (53.08 ± 12.25 vs.59.39±9.74,t=2.39,P<0.05) and total score (23. 91 ±2. 57 vs. 25. 27 ±2.14, t =2.40, P <0.05) of SGRQ were significantly lower in group Ⅱ compared to group Ⅰ. Six adverse events,including dry mouth (n =4), palpitation (re = 1) , constipation (n = 1), were observed in tiotropium alone group during the treatment period. Eleven adverse events were observed in combination treatment group, including dry mouth (re = 3) ,stomach discomfort or nausea (n = 3), diarrhea (re = 2) , palpitation (n = 2), constipation (n = 1) . The incidences of adverse reactions of two groups had no significant difference (P > 0. 05). Conclusion Compared with the single application of tiotropium, tiotropium plus sustained-release theophylline therapy can alleviate symptoms and improve life quality in patients with stable moderate COPD,without significantly increasing adverse reactions.

Pelvic inflammatory disease sequela (chronic pelvic inflammation) is one of the diseases that affect women's health conditions, and leads to large economic burden. Chinese Material Medica (CMM) plays an impor-tant role in treating pelvic inflammatory disease sequela (chronic pelvic inflammatory). However, due to the lack of Evidence-based Pharmacoeconomic Evaluation Technical Essentials of CMM in Treatment of Pelvic Inflamma-tory Disease Sequela (Chronic Pelvic Inflammatory), non-standard phenomenon often appears in the research liter-ature, such as the selection of research methods, viewpoint of research, determination of cost, effect and utility. Thus, the publish of Evidence-based Pharmacoeconomic Evaluation Technical Essentials of CMM in Treatment of Pelvic Inflammatory Disease Sequela (Chronic Pelvic Inflammatory) is essential for the pharmacoeconomic evalua-tion of CMM in treating pelvic inflammatory disease sequela (chronic pelvic inflammatory).
