Objective To evaluate the surgical effects and methods of bipolar plasmakinetic enucleation and resection of prostate for benign prostatic hyperplasia (BPH). Methods A total of 120 patients with BPH were performed bipolar plasmakinetic resection of prostate and bipolar plasmakinetic enucleation of prostate for BPH. The blood loss,operative time,catheterization time,hospital stay and complications were monitored and analyzed. Results All of the patients were operated successfully. All the cases were followed up for 3-6 months. No urethral stricture, bladder neck contracture, rebleeding, permanent urinary incontinence occurred. The maximum flow rate increased from (6.1 ± 2.5) ml/s peroperative to (16.3 ± 2.2) ml/s at 3 months postoperative,and international prostate symptoms score (IPSS) decreased from (23.8 ± 5.2) scores peroperative to (4.6 ± 3.9) scores (P < 0.01). Conclusion Bipolar plasmakinetic enucleation and resection of prostate for BPH has many advantages such as thorough excision of the prostate,less blood loss in operation,less operation time and complications, higher security and quicker recovery, so it deserves clinical application.

Objective To investigate the association between serum level of secretory type Ⅱ phospholipase A2 (sPLA2 Ⅱ a) and carotid intima-media thickness (CIMT) in elderly patients with metabolic syndrome (MS).Methods A total of 124 consecutive MS patients aged over 65 years were enrolled and another 90 elderly non-MS subjects were served as controls.The serum concentration of sPLA2 Ⅱ a was measured by enzyme-linked immunosorbent assay.Blood pressure,blood lipids and blood glucose levels etc.were also measured.The carotid intima-media thickness was examined by color Doppler ultrasonography.Results Serum level of sPLA2 Ⅱ a was significantly higher in elderly MS patients than in control group [(4.41±1.55)μg/L vs.(2.39±0.97)μg/L,P＜ 0.05].Compared with the control group,elderly MS patients showed CIMT was significantly increased [(1.17±0.24) mm vs.(0.89±0.24)mm,P＜0.05].Serum level of sPLA2 Ⅱ a were higher in elderly obesity patients than in normal BMI subjects [(4.76±0.99)μg/L vs.(2.84±0.54)μg/L,P＜0.05].Multiple regression analysis indicated that sPLA2 Ⅱ a level was an independent risk factor for CIMT in elderly MS patients after adjusting for the effects of BMI,IL-6 and high sensitive C-reactive protein (hs CRP) on CIMT(r=0.38,P＜0.01).Conclusions Serum level of sPLA2 Ⅱ a is increased in elderly MS patients and is independently correlated with CIMT,which has a predictive value for atherosclerosis,sPLA2 Ⅱ a may be involved in the process of vascular endothelial injury.

ObjectiveTo evaluate the feasibility and value of mini-clinical evaluation exercise (Mini-CEX) in clinical neurology practice.MethodsNinety-four interns were randomly divided into observation group and control group,students in control group were teached and managed in accordance with existing management while those in observation group were evaluated by teachers after the 1 st,2nd and 3rd week.At the end of clinical practice,all the students( including students in control group and observation group)were cross assessed by teachers based on the methods mentioned above.Results The time to complete the assessment was about 25 - 40 min.The scores of nervous system examination at the end of the training were significant different between observation group and control group and the scores of diagnosis and treatment on the basis of examination were also significant different between observation group and control group ( P ＜ 0.05 ).ConclusionThe Mini-CEX assessment and feedback to promote teaching effect is feasible in the practice process of neurology,it can make up for the deficiency of current examination.

OBJECTIVETo use combined G-banding and array-comparative genomic hybridization (aCGH) for the prenatal diagnosis of a fetus with 5q35 deletion syndrome.

METHODSChromosomal karotypes of the fetus and parents were analyzed with G-banding analysis. aCGH was performed to detect minor chromosomal structural abnormalities.

RESULTSThe karyotype of the fetus was ascertained as 46, XY, t(5;10)(q35;p13), and the karyotypes of the parents were normal. aCGH has identified a de novo 1.68 Mb deletion at 5q35.2q35.3 and a 1.44 Mb duplication at 10p14p13.

CONCLUSIONaCGH has a higher resolution and greater accuracy for mapping chromosomal aberrations and is a useful supplement for G banding karyptyping analysis.

They helped students better remember the type of bone fractures and how to choose the correct internal fixation methods. The teaching effect was satisfactory. Conclusions 3D modeling and printing technology was applied to build bone fracture models to assist clinical teaching at the department of traumatic orthopedics. It was found that the printed 3D bone fracture models can stimulate students' enthusiasm for learning and improve their learning effect. This method has good application value.

OBJECTIVE： To provide theoretical basis and data support for community extended prescription management and pharmaceutical care. METHODS： Data of all patients using extended prescription from 2017 to 2018 were derived from the health information system database of Jinshan district of Shanghai and 11 streets towns under its jurisdiction. Retrospective survey was used to analyze the basic medical information of extended prescription patients and the compliance with extended prescription execution （insisting on dispensing drugs through extended prescription within 2 years）， and the factors affecting compliance were analyzed. RESULTS： From 2017 to 2018， there were 4 835 patients with Jinshan district extended prescription， with prescribing rate （number of extended prescriptions/number of prescriptions） of 2.08％， mainly patients over 60 years old （4 038 cases， 83.51％） and patients with common chronic diseases [4 793 casetimes， 83.18％ （4 793/5 763）]； there was statistical significance in the prescribing rate of extended prescription among different streets and towns （P＜0.05）. The overall compliance rate of extended prescription patients in Jinshan district was 81.62％ （62.02％-88.84％）. There was no significant difference in compliance rate of extended prescription execution between male and female patients （P＞0.05）. Age， type of disease and types of extended prescription drugs had influence on compliance rate of extended prescription patients. Compliance rate of extended prescription in patients under 40 years of age or hypertension and chronic airway disease or those who were given one kind of drug was lower than other patients in same group （P＜0.05）. CONCLUSIONS： Big data can be used for monitoring the compliance of extended prescription in the future. At the same time， pharmacists participating in family doctor team formulate relevant guidance and education for poor compliance group so as to improve the rationality and effectiveness of extended prescription for patients.

Femoral neck fracture (FNF) in the elderly patients is currently a major health challenge worldwide, with excessive consumption of medical resources, high incidence of complications as well as suboptimal outcome and prognosis. Hip joint arthroplasty (HJA) has been the mainstream treatment for FNF in the elderly, but the conventional surgical approaches and techniques are still confronted with a series of bottlenecks such as dislocation, limp and limb length discrepancy. In recent years, direct anterior approach (DAA) for HJA (DAA-HJA) has been a major new choice in the field of joint replacement, which achieves improved clinical effectiveness of HJA in the treatment of elderly FNF, due to the fact that DAA approach involves the neuromuscular interface and accords with the idea of soft tissue retention and enhanced recovery after surgery. However, there is still a lack of unified understanding of standard technique and procedure of DAA-HJA in the treatment of elderly FNF. Therefore, relevant experts from the Hip Joint Group of Chinese Orthopedics Association of Chinese Medical Association, Youth Arthrology Group of Orthopedic Committee of PLA, Orthopedic Committee of Chongqing Medical Association, Branch of Orthopedic Surgeons of Chongqing Medical Doctor Association and Sport Medicine Committee of Chongqing Medical Association were organized to formulate the " Chinese expert consensus on the technical standard of direct anterior hip arthroplasty for elderly femoral neck fracture ( version 2023)" based on evidence-based medicine. This consensus mainly proposed 13 recommendations covering indications, surgical plans, prosthesis selections, surgical techniques and processes, and postoperative management of DAA-HJA in elderly patients with FNF, aiming to promote standardized, systematic and patient-specific diagnosis and treatment to improve the functional prognosis of the patients.
