ABSTRACT
Ulna impingement syndrome is the main cause of wrist ulnar pain.It is caused by repeated impingement between the ulnar bone,triangular fibrocartilage complex,lunate bone and triangular bone,resulting in long-term overload of the ulnar side of wrist,affecting local blood supply and joint lubrication fluid nutrition disorders,and finally causing a series of pathological changes and clinical symptoms of joint degenerative diseases.The main clinical manifestations are pain on the ulnar side of the wrist,which gradually aggravated with repeated strong grasping activities,forearm pronation or ulnar deviation of the wrist.At present,the diagnosis of ulna impingement syndrome mainly depends on the symptoms,physical examination,imaging examination and wrist arthroscopy.Conservative treatment can be selected for ulnar impaction syndrome,but the effect is often poor.Therefore,surgery is still the main treatment.The surgical methods mainly include ulna shortening osteotomy,Wafer,Darrach and Sauvé-Kapandji,and the former two are the most commonly used.This article reviews the progress of diagnosis and treatment of ulna impingement syndrome.
ABSTRACT
Objective:To explore the effect of core muscle strength training intervention on postoperative rehabilitation of patients after total knee arthroplasty, and to provide reference for the rehabilitation of patients after total knee arthroplasty.Methods:A total of 109 patients with total knee arthroplasty who were admitted to Medical Health Group of First People′s Hospital of Xiangshan County from May 2020 to July 2021 were selected as the research objects, and were divided into an intervention group of 54 cases and a control group of 55 cases according to the random number table method. The control group received conventional rehabilitation methods after surgery, and the intervention group received core muscle strength training on the basis of conventional rehabilitation. The intervention time was 6 weeks. The knee joint function, balance function and activities of daily living were evaluated by Hospital for Special Surgery Knee Score, Berg Balance Scale, modified Barthel Index before and after intervention and the results were compared between the two groups.Results:In the end, there were 50 cases in the intervention group and 52 cases in the control group. There was no significant difference in the score of the knee joint function, balance function and activities of daily living before intervention between the two groups( P>0.05). The scores of the knee joint function, balance function and activities of daily living were (74.78 ± 3.12), (46.50 ± 3.82), (92.80 ± 5.17) points in the intervention group, and (72.15 ± 3.31),(44.44 ±3.66),(89.42 ± 4.50) points in the control group, the differences were statistically significant ( t=4.12, 2.78, 3.52, all P<0.01). The knee joint function recovery grade in the intervention group was higher than that in the control group, and the difference was statistically significant ( Z=3.43, P<0.01); the degree of dependence on self-care ability in daily life in the intervention group was lower than that in the control group, and the difference was statistically significant ( Z=3.98, P<0.01). Conclusions:Core muscle strength training can effectively improve postoperative knee function, balance function and activities of daily living in patients with total knee arthroplasty. This program is practical in clinical work and has clinical application value.
ABSTRACT
Objective To investigate the compliance status of secondary prevention in patients with coronary artery disease (CAD) following revascularization.MethodsA total of 512 patients with CAD who received procedures for coronary revascularization were enrolled in the study from January 2009 to October 2010,including 472 cases of percutaneous coronary intervention stenting,25 cases of coronary artery bypass grafting and 15 cases of stenting plus bypass.The demographic information,prophylactic drug therapies, lifestylechangesandmodifiableriskfactorsweresurveyedwithquestionnaires,anthroposomatologicalmeasurementsandlaboratorytestsinpatients3monthsaftercoronary revascularization.ResultsThe proportion of patients on statins,aspirin,β-blockers,angiotensin-converting enzymeinhibitors/angiotensinreceptorblockers(ACEIs/ARBs)andinfluenzavaccinationwere 81.4％ (417/512),93.9％ ( 481/512 ),82.0％ ( 420/512 ),76.2％ ( 390/512 ) and 3.7％ ( 19/512 ) respectively.Based on the criteria recommended by the American Heart Association/American College of Cardiology (AHA/ACC)Guidelines for Secondary Prevention for Patients with Coronary and Other Atherosclerotic Vascular Disease: 2006 Update, the percentages of achieving therapeutic targets of modifiable risk factor management were as follows:glycosylated hemoglobin (90.2％,462/512 ),total cholesterol ( 68.6％,351/512 ),triglycerides ( 58.8％,301/512 ),high-density lipoprotein cholesterol ( 91.6％,469/512 ),low-density lipoprotein cholesterol ( 44.5 ％,228/512 ),systolic pressure ( 75.2 ％,385/512 ) and diastolic pressure (90.4％,463/512 ) respectively.And the proportions of improved lifestyle were as follows:smoking cessation/non-smoking 81.4％ (417/512),diet control 78.5％ ( 402/512 ),achieving weight targets 61.7％ (316/512)and regular exercise 58.2％ (298/512).ConclusionsThere is a relatively high percentage of standardized antiplatelet therapy and continuous statins medication in patients with coronary artery disease following revascularization. However,many significant modifiable risk factors have not been controlled optimally and lifestyle of patients needs further improvement. There is still a considerable scope for further improvement of secondary prevention in this group of patients.
ABSTRACT
Objective: To study the new device and technology in prepartion of superfined Chinese herbal medicine powders. Methods: Improving the Trost jet mill was to divide continually the feed and the coarse grains classified from a circular disc into two two phase flow by means of a especial four way pipe in mixing. and to impact with high speed oppositely each other, the superfined powders are prepared. Results: The superfined powders of ginseng, boat fruited sterculia seed and balsam pear are successfully prepared to guarantee 10～15?m in diameter. Conclusions: It is very effective to pulverize Chinese herbal medicine with this device in mass production.
