Objective: To investigate the effect of cognitive intervention on the therapy to Chronic prostatitis(CP) following Sexually Transmitted Diseases(STD). Methods: 84 patients were divided into two groups, as control group(n=42) in which prostant was locally used and the intervention group(n=42) which received cognitive Intervention therapy based on the locally using prostant. After a month, the therapy effect was evaluated. Results: Compared with control group, the subjective syndrome in intervention group was improved much more apparent receiving therapy one month later(P 0.05). Conclusion: Cognitive intervention is an effective method to improve the subjective syndrome of CP following STD; so a clinical medicine should study psychology.

The extensor tendon rupture is a common disease.Traditional management includes "8" suture and cross suture.But second operation is commonly needed for the reason of postoperative Nodules or adhesion.So a new technique is invented by the author:micro-weave suture combined with sodium hyaluronate.The new technique has improved dynamic intensity of the tendon and avoided postoperative adhesion.In this paper,this technique is reviewed.

Children avascular necrosis of femoral head is a self-healing,self-limiting and non-systematic disease occouring locally in femoral head of children.The purpose of traditional conservative and surgical treatments is to improve blood circulation,decrease intraosseous pressue,decrease arthrosis pressure,reduce capital mechanical pressure to the femoral head and increse its containment.Anyway,no treatment could stop the progress of coxa plana and degeneration of the bone,which could lead to disorder of the hip.As a new technique,autologous bone marrow stem cellular transplantation has obtained preliminary curative effect.It has been proved to be a new effective treatment of children avscular necrosis of the femoral head with combined use of tissue enginering bone.

Objective To evaluate the diagnostic and therapeutic value of emergency Angiography in massive gastrointestinal hemorrhage.Methods 19 patients with massive gastrointestinal hemorrhage,failed by internal medicine or under instable condifion,were undergone emergency angiographic diagnosis with hemostatic or embolismic agent infusion at the same time,and were transfered fo surgical department for emergency surgery on time,then the findings of angiographic diagnosis were compwred with the ones of operation.Results All the patients were performed emergency angiography successfully.and the localigation diagnosis rate is 100%.Conclusion Emergency angiography established orientation goal for the emergency surgery,which is safe even if blood pressure of the patients was uncertain by internal medicine,and hemostasis treatment also makes chance for emergency surgery.

Objective:To design a new automatic cap opening device consists of holding mechanism, open mechanism, improve mechanism, rotating mechanism and recycling mechanism in order to resolve the poor adaptability, complex structure and lower liability problem for specimen container in the biological specimen pretreatment system.Methods: This paper designed a automatic equipment to remove the rubber cap and screw cap. This equipment is compatible with the different specification specimen containers and the container cap, and the specimen container cap was stepped up and rotated with same power component.Results: The application of equipment has reduced the manufacturing cost and maintenance cost for specimen container, improved the system reliability, solved the current technical problems of the equipment, such as poor adaptability and lower liability. Conclusion: The design of equipment mainly adapts to CS-6400 series of automatic biochemical analyzer, and it can improve the detection efficiency of biological specimen, reduce the cross contamination and satisfy the practice necessity for clinical detection.

[Objective]To observe the effect of cross-finger-like micro-weave suture plus sodium hyaluronate technology in the treatment of extensor tendon injury by the animal experiments.[Method]Twenty-eight Leghorn chickens were randomly divided into four groups,double-cross stitching was used in group A in the treatment of extensor tendon injury,double-cross stitching plus sodium hyaluronate in group B,cross-finger-like micro-braided suture in group C,cross-finger-like micro-braided suture plug sodium hyaluronate surgery in group D.Six weeks after surgery,morphological observation,histological observation and biomechanical determination were done by using the naked eye and microscope,as well as the results of the experiments were statistically analyzed.[Result]In the group of the cross-finger-like micro-weave suture plus sodium hyaluronate,tendon grew in good shape without nodules after surgery,pseudome was formed around tendon,tendon cells mostly arranged regularly in bunches,maximum load was (70.9 ? 5.68) N on average,it was significantly larger than those in other groups and there was a significant difference by the analysis of variance (P

Developing enterprise education in medical colleges and universities must have the following basic conditions:renewing medical educationconcept;establishing a teacher troop on teaching enterprise;building a good enterprise education atmosphere and strengthening practice teaching.

COVID-19 is an acute respiratory infectious disease caused by 2019-nCoV, which has become a major global public health event and a serious threat to human health. So far, specific antiviral drugs, safe and effective vaccines for 2019-nCoV are still under development, so there is an urgent need to find alternative strategies for the treatment of COVID-19. Convalescent plasma(CP) contains high titer neutralizing antibodies from patients recovering from infectious diseases, which has been used in the treatment of major infectious diseases such as severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (MERS), and achieved satisfactory clinical results. Therefore, CP from COVID-19 patient is a meaningful choice for the treatment of severe or life-threatening COVID-19 patients, but its potential risks need to be studied. This review focuses on the clinical mechanism, collection points, clinical application and potential benefits and risks of clinical treatment of CP from COVID-19 patients, which will provide reference for the clinical application of CP from COVID-19 patients.

ObjectiveTo investigate the protective effects of panax quinquefolium 20s-protopanaxtriol saponins (PQTS) on ventricular remodeling in rats with pressure overloaded hypertrophic myocardium.Methods Wister rats were randomly divided into operation,model,positive captopril,and low,moderate,high PQTS groups.The model of pressure overload-induced ventricular remodeling was established through the method of rat's abdominal aorta deligation.After 6 weeks of PQTS treatment ( 12.5,25.0 and 50.0 mg · kg-1 · d-1,i.p),myocardial morphological and hemodynamic parameters were determined.The content of malondialdehyde (MDA) and activity of superoxide dismutase (SOD)in serum,and the concentrations of prostacycline (PGI2),thromboxane A2 (TXA2),endothelium (ET) and angiotensin Ⅱ( Ang Ⅱ ) in plasma were also determined.ResultsCompared with remodeling group,PQTS could inhibit myocardial pathological changes,decrease significantly ventricular weight and cardiac coefficient,increase significantly systolic blood pressure,diastolic blood pressure,mean arterial pressure,left ventricular systolic pressure and the maximum left ventricular pressure rising and dropping rates(dp/dtmax),reduce the heart rate and left ventricular end-diastolic pressure in ventricular remodeling rats.PQTS could also decrease the content of MDA and enhance significantly activity of SOD in serum.In addition,PQTS could decline the contents of ET,Ang Ⅱ and TXA2 in plasma while increase significantly the content of PGI2 in plasma and PGI2/TXA2 ratio(P＜0.05 or P＜0.01).ConclusionsPQTS has protective effects on ventricular remodeling through improving systolic and diastolic function in ventricular remodeling rats,increasing anti-oxidase activity,reducing the damage of free radicals and vasoactive substance onmyocardium,and correcting disequilibrium of PGI2/TXA2 in ventricular remodeling rats.
