Clinical efficacy of different rehabilitation modes for lumbar degenerative diseases after operation / 中国骨伤

OBJECTIVE@#To compare clinical effects of different postoperative rehabilitation modes on lumbar degenerative diseases, and explore influence of rehabilitation mode and other factors on postoperative effect.@*METHODS@#From June 2013 to July 2016, totally 900 patients were admitted from nine tertiary hospitals in Beijing to perform single segment bone grafting and internal fixation due to lumbar degenerative diseases were prospectively analyzed. There were 428 males and 472 females, the age of patient over 18 years old, with an average of (51.42±12.41) years old;according to patients' subjective wishes and actual residence conditions, all patients were divided into three groups, named as observation group 1 (performed integrated rehabilitation approach and orthopedic treatment model intervention), observation group 2 (performed integrated rehabilitation approach and orthopedic treatment, classified rehabilitation model intervention), and control group(performed routine rehabilitation model intervention). Visual analogue scale(VAS), Oswestry Disability Index(ODI) and Japanese Orthopaedic Association (JOA) were used to evaluate postoperative efficacy among three groups at 24 weeks. Possible factors affecting the postoperative efficacy including age, age grouping, gender, body mass index (BMI), BMI grouping, education level, visiting hospital, payment method of medical expenses, preoperative complications, preoperative JOA score, clinical diagnosis, surgery section, operative method, intraoperative bleeding volume, postoperative complications and rehabilitation mode were listed as independent variables, and postoperative ODI score at 24 weeks as dependent variables. Univariate analysis was used to analyze relationship between influencing factors and postoperative efficacy. Multiple linear regression was used to analyze relationship between influencing factors, rehabilitation mode and postoperative ODI score at 24 weeks, in further to find out the main reasons which affect postoperative efficacy, and to analyze impact of rehabilitation mode on postoperative efficacy.@*RESULTS@#All patients were followed up for 24 weeks after operation. All incisions healed at stage I with stable internal fixation. (1)Evaluation of postoperative efficacy:① There were no statistical differences in preoperative VAS and ODI among three groups(@*CONCLUSION@#Preoperative JOA score, gender, age could predict postoperative clinical effects of lumbar degenerative diseases in varying degrees treated with single level bone graft fusion and internal fixation. Different rehabilitation modes could improve clinical effects. Intergrated rehabilitation orthopedic treatment model and integrated rehabilitation approach and orthopedic treatment with classifiedrehabilitation model are superior to conventional rehabilitation model in improving patients' postoperative function and relieving pain, which is worthy of promoting in clinical.

A Discussion About the Organic Combination of National Drug Sampling and Testing for Quality Evaluation and National Drug Standards Improvement / 中国药学杂志

OBJECTIVEP: To explore the necessity and feasibility of organic combination of the national drug sampling and testing for quality evaluation and national drug standards improvement. METHODS: Through analysis of the similarities and differences of the two working modes and their complementarity, the problems that may arise in the connection of work were identified. The mechanism and counter measures to promote the organic combination of the two working modes were put forward. RESULT AND CONCLUSION: It was suggested that a communication mechanism should be established in time to strengthen the connection and interaction between the national drug sampling and testing for quality evaluation and national drug standard improvement, thus to avoid wasting resources and timely translate feasible suggestions into national drug standards.

Clinical safety about repairing the peripheral nerve defects with chemically extracted acellular nerve allograft / 中华外科杂志

<p><b>OBJECTIVE</b>To discuss the clinical safety about repairing the peripheral nerve defects with the acellular allogeneic nerve.</p><p><b>METHODS</b>The 41 patients (male 38, female 3, age 10 - 55 years old, average 28.9 years old) who were performed chemically extracted acellular nerve allograft transplanting to repair nerve defects from 2002 to 2011. The average interval from injury to nerve repairing was 4.1 months (range, 10 hours to 9 months). There were 41 cases nerve defects including 10 brachial plexus nerves, 3 radial nerves of upper arm, 4 ulnar nerves of forearm, 12 digital and toe nerves, 2 sciatic nerves, 2 femoral nerves, 3 tibial nerves and 5 common peroneal nerves. There were 12 cases combined fractures and 20 soft tissue injury or defects. The average length of the nerve allograft to bridge the nerve defects was 6.1 cm (range, 2 - 10 cm). No immunosuppressive drugs were used in all cases. The clinical safety was evaluated through physical examination, blood biochemistry and immunity detection.</p><p><b>RESULTS</b>All cases were followed up post-operation. They got primary wound healing except 2 superficial infection who got delay healing through dressings changing. No any adverse effects happened including immunological rejection, hypersensitivity reaction, deep infection, hepatotoxicity and nephrotoxicity.</p><p><b>CONCLUSIONS</b>It is safe and feasible to repairing human peripheral nerve defects with chemically extracted acellular nerve allograft.</p>
