Objective:To investigate the prevalence,and the factors that influence depressive symptoms among chronic respiratory disease patients in tertiary hospital.Methods:A total of 1713 outpatients and inpatients with chronic respiratory disease were selected from 8 tertiary hospitals in Jiangsu Province from July to September,2014 and screened according to the Hospital Anxiety Depression Scale-D (HADS-D).A questionnaire developed by this research group,was used to collect demographic and clinical information.Logistic regression was used to identify factors that were associated with depressive symptoms.Results:The overall rate of depressive symptoms was 46.0％.Multiple logistic analysis showed that spinsterhood (OR ＝ 0.45),higher education level (middle school /high school/technical school OR ＝0.65;college degree or aboveOR ＝0.28),BMI ≥24 (OR ＝0.71) were associated with decreased risk of depressive symptoms (P ＜ 0.05).B MI ＜ 18.5 (OR ＝ 1.52,),average income of family ≥10000 RMB (OR ＝ 1.37-1.96),limited daily activities (OR ＝ 1.72),poorer sleep quality (OR ＝ 1.45),and negative life events (OR ＝ 1.62) were associated with increased risk of depressive symptoms (P ＜ 0.05).Conclusion:The prevalence of depressive symptoms among chronic respiratory disease patients in tertiary hospitals in Jiangsu Province was higher.Marital status,education level,income,BMI,limited daily activities,subjective sleep quality,negative life events may be the related factors of depressive symptoms of chronic respiratory diseases patients.

OBJECTIVE: To study the effects of Wuzhi capsule/schisantherin A (SchA) combined with cyclophosphamide on the pharmacokinetics of cyclophosphamide (CTX) in rats. METHODS: A total of 36 rats were randomly divided into CTX group (via tail vein, iv, CTX solution 300 mg/kg), CTX+WZC group (ig, Wuzhi capsule 300 mg/kg+via tail vein, iv, CTX solution 300 mg/kg), CTX + SchA low-dose, medium-dose, high-dose and excessive high-dose groups (ig, SchA 30, 300, 3 000, 30 000 μg/kg+via tail vein, iv, CTX solution 300 mg/kg) with 6 rats in each group. Blood samples were collected from orbital venous plexus of rats before medication and 0.083, 0.25, 0.5, 1, 2, 3, 4, 6, 8, 12, 24, 36, 48 h after medication.UPLC-MS/MS method was applied for concentration determination of CTX and its metabolites [de-chloroethyl CTX (DC-CTX), 4-ketone CTX (4-keto CTX), carboxyl phosphamide (CPM)] in plasma of rats. The plasma concentration-time curve was obtained. The pharmacokinetic parameters were fitted by using DAS 2. 0 software. RESULTS: The maximum plasma concentration (cmax) of DC-CTX in CTX group, CTX+WZC group, CTX+SchA low-dose, medium-dose, high-dose and excessive high-dose groups were (22 167. 85 ±2 844. 93), (10 920. 53 ± 1 490. 89), (18 951. 29 ± 1 558. 81), (18 622. 08 ± 791. 19), (18 515. 20 ± 2 560. 61), (15 133. 21 ± 1 305. 07) μg/mL, respectively; the area under the curves (AUCo-48 h) were (173 864. 01 ± 65 342. 21), (100 996. 98 ± 33 530. 02), (137 028. 16 ± 45 975. 19), (131 650. 18 ± 53 196. 41), (113 699. 40 ± 34 131. 36), (110 773. 27 ± 30 307. 15) μg·mL/h, respectively. Compared with CTX group, cmax of DC-CTX in CTX group, CTX+SchA low-dose, medium-dose, high-dose and excessive high-dose groups were decreased by 50. 74％, 14. 51％, 16. 10％, 16. 48％, 31. 73％, respectively. AUC0-48 h were decreased by about 42. 23％, 21. 45％, 24. 63％, 33. 37％, 36. 55％, respectively; with statistical significance (P<0. 05). The pharmacokinetic indexes as t1/2, tmax had no significant change. CONCLUSIONS: To some degree, both WZC and SchA can reduce the generation of DC-CTX, which indicates both of them can inhibit CTX toxicity metabolism pathway so as to reduce the generation of toxic metabolite chloroacetaldehyde. The inhibitory effect of SchA on toxicity metabolism pathway is weaker than that of WZC, and does not have a dose-dependent inhibitory effect.

AIM: To analyze the causes of blindness and low vision in patients with visual disability in Yangpu District of Shanghai from 2019 to 2022.METHODS:Cross-sectional study. A total of 1 604 patients who participated in the evaluation of visual disability in Shanghai Yangpu District Kongjiang Hospital, from April 2019 to December 2022 were selected for the study. The grade of visual disability and the main causes of blindness and low vision were determined by trained doctors.RESULTS:A total of 804 patients with visual disabilities were identified, with 87.31% aged 60 and above. The causes of visual disability were high myopic retinopathy(30.47%), age-related macular degeneration(23.26%), glaucoma(17.04%), and diabetic retinopathy(11.07%). Glaucoma(36.96%)is the leading cause of blindness.CONCLUSION: The majority of patients with visual disability are aged 60 years and above. More attention should be paid to the elderly population. Comprehensive prevention, treatment and rehabilitation measures should be applied in different diseases based on classification, so as to early reduce the occurrence of visual disability.
