Objective To evaluate the effect of community management of diabetic patients with hypertension in Beijing Cuigezhuang community in last three years.Methods A community diabetic management program was started from 2007 in Beijing Cuigezhuang community.Three hundred and seventy six patients who participated in the program for more than 3 years were enrolled in the study, including 196 with type 2 diabetes mellitus (T2DM) only (DM group) and 180 with T2DM and hypertension (DMH). The control rate of blood glucose, blood pressure, lipids and the comprehensive control rate were compared between two groups after 3-year intervention.Results There were no significant differences in age, gender ratio, course of diabetes, education background, monthly income and the history of stoke between two groups;while prevalence of dyslipidemia in DMH group was significantly higher than that in DM group [41.7%(75/180) vs.24.5%(48 196),χ2 =11.938,P=0.001].Compared with the baseline data, the types of antidiabetic drugs used were not significantly changed in two groups after 3-year intervention ( DM group:1.32 ±0.81 vs.1.31 ±0.93, t=-0.155, P=0.877, DMH group:1.43 ±0.72 vs.1.48 ±0.82, t=0,831, P =0.407) .The types of antihypertensive drug in DMH group were significantly decrease. (1.12 ±0.77 vs.1.25 ±0.45, t=2.484, P=0.014), while the rate of statins usage in DM group was significantly increased [13.3%(26/196) vs.5.1%(10/196),χ2 =7.830, P=0.005].The hemoglobin A1c (HbA1c) levels in DM group was decreased [(7.4 ±1.5)% vs.(7.8 ±2.1)%, t=2.586, P=0.011].The systolic pressure [(129 ±12) mmHg (1 mmHg=0.133 kPa) vs.(133 ±16) mmHg, t=3.503, P=0.001] and the diastolic pressure [(80 ±8) mmHg ratio (82 ±10) mmHg, t=2.436, P=0.016] in DMH group were significantly declined. The average LDL-C level [ DM group: ( 3.0 ± 0.9) mmol/L vs.(3.2 ±1.0) mmol/L, t =2.165, P=0.032; DMH group (2.9 ±1.0) mmol/L vs. (3.2 ±1.1) mmol/L, t=3.210, P=0.002] were also significantly decrease.Compared with the baseline, the comprehensive control rates of blood glucose, blood pressure and lipid level were increased in both groups [DM group:9.7% (19/196) vs.6.1%(12/196),χ2 =1.716, P=0.190, DMH group 13.9%(25/180) vs.5.0%(9/180),χ2 =8.315, P =0.004] .Conclusions The community management program is effective for improvement of comprehensive control rates of blood glucose, blood pressure and blood lipids in diabetic patients with hypertension in Beijing Cuigezhuang community.

Objective To investigate the effect of Bi-level positive airway pressure ventilation (BiPAP) combined with Seretide on quality of life of elder patients with moderate and severe chronic obstructive pulmonary disease (COPD) and type Ⅱ respiratory failure.Methods Eighty elderly patients with moderate to severe COPD and type Ⅱ respiratory failure were selected and randomly divided into observation group (n =40) and control group(n =40).The two groups were given conventional anti infection,oxygen inhalation,spasmolysis,expectorantand other conventional treatment,and the use of BiPAP ventilator assisted ventilation.Patients in observation group were administered the combined of Seretide and BiPAP treatment,and patients in control were received only BiPAP.Arterial blood gases before and after 7 d treatment,lung function and quality of life evaluation results (SQGR score) before and after 7 d,3 months and 6 months treatment,were measured.Results There were significant differences in terms of arterial blood gases,pulmonary function key indicators,SQGR score between two groups before and after treatment(P ＜ 0.01).PaCO2 was significantly after 7 d of treatment in observed group was (42.9 ± 7.9) mmHg,lower than that of the control group ((47.6 ± 8.0) mmHg; t =8.467,P ＜0.001).There was no significant difference in terms of forced expiratory volume in one second(FEV1) in both groups at 7 d,3 months,6 months after treatment (P ＞ 0.05).FEV1/forced vital capacity (FVC) in two group at 3 months,6 months after treatment were different compared to 7 d after treatment (observation group:(49.9 ±5.1)％ and (47.1 ±4.2)％,(50.2 ± 5.0)％ and(47.1 ±4.2)％ ;control group:(49.0 ± 5.4)％and (46.6 ± 5.9) ％,(49.8 ± 5.2) ％ and (46.6 ± 5.9) ％ ; P ＜ 0.05).SQGR score in observation group at six months after treatment were (40.8 ± 8.5),significantly lower than that of 7 d after treatment(45.9 ± 10.8),P ＜ 0.05),and significantly lower than the control group after 6 months of treatment ((40.8 ± 8.5) vs (46.0± ± 8.0),P ＜ 0.05).Conclusion Seretide combined with BiPAP treatment can significant improve lung function and the quality of life of patients with moderate and severe COPD and type Ⅱ respiratory failure.

Objective To explore the diagnostic value and optimal cut-off point of symptom index (SI) in gastroesophageal reflux-induced chronic cough (GERC).Methods The recordings of multichannel intraluminal esophageal impedance and pH monitoring were retrospectively analyzed in 118 patients with suspicious GERC.SI for all the refluxes,acid reflux and non-acid reflux was calculated respectively by analyzing the temporal association between detected reflux and cough recorded on diary card.Based on the favorable response to the anti-reflux therapy,the diagnostic value for GERC of SI was evaluated and compared with that of the symptom association probability (SAP).Results GERC was definitely determined in 100 patients (84.7％).When SI for all the refluxes was used for the diagnosis of GERC,the cut-off point of ≥45％ had the highest diagnostic efficacy,with the sensitivity of 56.0％,the specificity of 83.3％and Youden index of 0.393.SI for acid or non-acid reflux had the same optimal cut-off point of ≥30％ and presented with the similar efficacy in the diagnosis of acid or non-acid GERC.Compared with SAP of ≥75％,SIforall the refluxes of ≥45％ had a lower sensitivity (56.0％ vs 75.0％,x2 =7.988,P=0.005),a higher specificity (83.3％ vs 44.4％,x2 =5.900,P =0.015) and the comparable positive or negative predictive value in the diagnosis of GERC.The diagnostic accuracy for GERC was further improved when combining SI for all the refluxes with SAP.Conclusion SI for all the refluxes has a diagnostic value similar to SAP and its optimal cut-off point for GERC may be ≥45％.
