Methods One hundred fifty two valvular disease patients with Af after cardiac valve replacement were randomized to 2 groups: Amiodarone group and control group (without anti arrhythmic drugs) after cardioversion. Af recurrence was observed during one year follow up. Results (1) No significant difference of Af recurrence betwe...
Objective To investigate the current situation of clinical studies on puerarin for angina pectoris and assess whether it is adequate to provide evidence for clinical practiice. Methods We collected all the published clinical studies on puerarin for angina pectoris from 1966 to October 2003, and assessed all the included reports according to international clinical epidemiological standard. Results 106 RCTs, 8 non-randomized controlled studies and 24 case series were included and analyzed. 126 studies reported diagnosis criteria, 10 desccribed inclusion criteria; 3 studies were quasi-random, 1 double blind, 4 single blind; no study reported follow-up; 117 studies reported adverse effects. Conclusions Currently the quality of studies on puerarin for angina pectoris is not good enough to provide reliable evidence for clinical practice.
Hypertension and its associated cardiovascular diseases such as stroke and ischemic heart disease result in a high burden of disease and health losses, making it the most burdensome disease in the world and one of the important public health issues in China. Currently Chinese scholars have carried out a large number of studies on the prevalence of hypertension, including regional and national prevalence studies. However, long-term follow-up studies on incidence of hypertension are relatively few and mostly limited to specific ages and regions. This paper summarizes the prevalence, incidence and epidemiological trend of hypertension in Chinese adults. The hypertension prevalence increased from 5.1% in 1959 to 27.5% in 2018, and presents an overall trend of high in the north and low in the south. The hypertension incidence is at a high level (the cumulative incidence was 33.4% after 22 years-follow-up), but there are few researches on the trend of hypertension incidence in huge region.
ObjectiveTo explore the regional and urban-rural disparities in the hypertension incidence of Chinese adults. MethodsBased on the data from the China Health and Nutrition Survey (CHNS), as well as the consumption level and altitude data from the National Bureau of Statistics and government official website, a robust multilevel Poisson regression was performed to explore the regional and urban-rural disparities in the hypertension incidence of Chinese adults, according to data and design types. ResultsAccording to the inclusion and exclusion criteria, 11 579 subjects and totaling 50 957 lines of data were enrolled. The 24 years follow-up results indicated that the crude incidence density of hypertension was 37.08/1 000 person years, with 40.51/1 000 person years for males and 34.13/1 000 person years for females. The robust multilevel Poisson regression results indicated that, by adjusting the high-level factors such as time, the proportion of the community mainly engaged in agricultural labor, and the consumption level of subjects, as well as sociodemographic characteristics such as age and gender, the Middle (RR=1.20, 95%CI 1.04 to 1.39), Northeast (RR=1.25, 95%CI 1.03 to 1.52), and Eastern (RR=1.25, 95%CI 1.05 to 1.48) China had a higher risk of developing hypertension than the Western China. The risk of hypertension in urban area was lower than that in rural area (RR=0.87, 95%CI 0.77 to 0.96). ConclusionThe incidence density of hypertension in China is relatively high, and male is higher than female. The incidence of hypertension in the Western China is lower than that in the Middle, Northeast and Eastern China, and urban area is lower than rural area.
Objective To determine the efficacy and safety of Amplatzer transcatheter closure and surgical closure for ostium secundum atrial septal defects. Methods MEDLINE (1966-July 2006), EMBASE (1966-July 2006), The Cochrane Library (Issue 2, 2006) and CBMdisc (1979-July 2006) were searched for randomized controlled trials or non-randomized controlled trials. Data were extracted by two reviewers using a specially designed extraction form. The quality of included trials was critically assessed. The Cochrane Collaboration’s RevMan 4.2 software was used for data analysis. Results Sixteen non-RCTs involving 2 043 patients were included. No deaths were reported in 14 trials. The other two trials reported one death respectively in the surgical group. Meta-analysis of 12 trials involving 1 722 patients showed that the procedure success rate for the Amplatzer group was lower than that for the surgical group [WMD:0.95, 95%CI (0.92,0.98)]. Similar results were also found in the complete closure rate in 24-hour follow-up [6 trials involving 1 106 patients, WMD:0.96, 95%CI (0.92 to 1.00)], the complication rate [16 trials involving 1 971 patients, WMD:0.27, 95%CI(0.21 to 0.35)] and the transfusion rate [14 trials involving 1 807 patients, WMD:0.03, 95%CI(0.02 to 0.06)]. Conclusions The success rate for Amplatzer device closure of ASD is lower than that of surgical repair. However, the complication rate, length of hospital stay and transfusion rate are lower or shorter for Amplatzer device closure than for surgical repair. Based on appropriate patient selection, Amplatzer closure of ASD is a safe and effective alternative to surgical repair.
ObjectiveTo investigate the early effectiveness of arthroscopic repair of supraspinatus tendon tears with douple-pulley suture-bridge. Methods The clinical data of 38 patients with supraspinatus tendon tears who met the selection criteria between September 2020 and July 2022 were retrospectively analyzed, and all of them were treated with arthroscopic double-pulley suture-bridge technique. There were 15 males and 23 females, aged from 43 to 77 years, with an average of 61.5 years. There were 15 cases of left shoulder and 23 cases of right shoulder. Seven cases had a history of trauma, and the other 31 cases had no obvious inducement. The main clinical symptoms of the patient were pain in lifting the shoulder joint and hug resistance test (+). The time from onset of symptoms to admission ranged from 6 to 19 months, with an average of 10.3 months. Flexion, abduction, and external rotation of the shoulder were recorded before operation and at 3 and 12 months after operation. Pain and function of the shoulder were evaluated by visual analogue scale (VAS) score, University of California Los Angeles (UCLA) shoulder score, and American Society of Shoulder and Elbow Surgeons (ASES) score before operation and at 12 months after operation. Tendon healing, tendon continuity, and tension were evaluated by MRI at 3-6 months after operation, and patient’s satisfaction was evaluated at last follow-up. ResultsAll the incisions healed by first intention, and there was no complication such as incision infection or nerve injury. All patients were followed up 12-34 months, with an average of 23.3 months. VAS score, UCLA shoulder score, and ASES score at 12 months after operation were significantly better than those before operation (P<0.05). The external rotation range of shoulder joint significantly improved at 3 and 12 months after operation (P<0.05), and it further improved at 12 months after operation when compared with 3 months after operation (P<0.05). There was no significant difference in the range of flexion and abduction at 3 months after operation when compared with those before operation (P>0.05), but the range of flexion and abduction at 12 months after operation significantly improved when compared with those before operation and at 3 months after operation (P<0.05). MRI reexamination was performed in 28 patients at 3-6 months after operation. Among them, 25 patients had intact supraspinatus tendon structure, good tension, and tendon healing, and 3 patients had type 1 retear. The remaining 10 patients refused to undergo MRI reexamination because of the satisfactory effectiveness. At last follow-up, 29 patients (76.3%) were very satisfied with the results, 6 (15.7%) were satisfied, and 3 (7.8%) were not satisfied. ConclusionArthroscopic double-pulley suture-bridge technique can achieve the effect of suture bridge operation, reduce the cost of operation and the risk of type 2 retear, and the early effectiveness is satisfactory, but the shoulder joint movement is limited within 3 months after operation.
During the medical rescue of Wenchuan earthquake, West China Hospital immediately shifted to the two-track emergent system mode. More works have been done in time to cure and treat those critically ill patients effectively and to protect the medical safety of patients. The Activated Contingency Plans for major disasters have been started up to evacuate safely those mild patients in the hospital,to prevent out of danger and other accidents. More works have done on the identification of the injured or patients to improve the accuracy and strictly implement the "three investigations and seven right" system to prevent a wrong operation, or a wrong prescription, or a wrong transfusion. We have worked carefully on the referral the wounded, to referr the wounded to those Hospitals in Chengdu or other province and to prevent security incidents.
