OBJECTIVE: To obtain scores in a community-dwelling population over 60 using the SF-36, to assess the reliability and validity of this general health questionnaire, and to analyze the difference in dimension scores among the elderly Chinese in Changsha. METHODS: We randomly selected 602 elders, aged 60 to 91 years, in multi-phases. All the subjects had resided in Changsha for at least one year. The reliability of the SF-36 was assessed by split-half reliability and Cronbach's alpha coefficient and the validity through factor analysis and correlation analysis, etc. The dimension scores of different people were obtained by analysis of variance and independent-samples t-test. RESULTS: The split-half reliability was 0.72 and the Cronbach's alpha coefficients of all the 8 dimensions were more than 0.8; the Pearson correlate coefficients of all the items to their dimensions were more than 0. 59. SF-36 contained 8 domains and 2 summary scales in the factor analysis. Health-related quality was different in different elders. CONCLUSION The SF-36 is practical in studying the quality of life among community-dwelling elders.

OBJECTIVETo evaluate the clinical value of high frequency ultrasound in diagnosing peripheral nerve diseases (PNDs).

METHODSFrom January 2003 to December 2006, 64 cases of PNDs were analyzed retrospectively. The ultrasound diagnosis was compared with the operative and pathological diagnosis.

RESULTSBased on the operative and histopathological results, in 38 patients with trauma or entrapment, 38 among 45 traumatic nerves were rightly diagnosed by ultrasound. The coincidence rate was 84.4%. In 26 patients with original peripheral nerve tumors (PNTs), including 20 neurilemmomas, 4 neurofibromas and 2 malignant neurilemmomas, 16 cases were diagnosed by ultrasound with a coincidence rate of 61.5%. The coincidence rates in limbs and trunk were 86.7% (13/15) and 27.3% (3/11) respectively.

CONCLUSIONSThe study suggests that high frequency ultrasound can locate peripheral nerve trauma precisely, assess the impair degree correctly and provide useful information for clinic diagnosis. The high frequency ultrasound brings better diagnosis outcome in limbs nerve tumors than in trunk.

OBJECTIVE: To investigate specific technique and clinical effects of closed folding top consolidation maneuver combined with splint fixation maneuver for consolidation and cedar bark external fixation splint for the treatment of double fractures of distal ulna and radius in children. METHODS: From January 2017 to December 2019, 17 children with double fractures of distal ulna and radius were treated with closed folded apex consolidation maneuver, including 13 males and 4 females, aged from 4 to 11 years old with an average of (7.29±2.34) years old. The fractures were fixed with cedar bark splint and followed up for 6 months, and alignment of fracture was evaluated according to the latest X-rays by follow up, and function of the affected limbs was evaluated by Anderson forearm function evaluation criteria. RESULTS: Fifteen of 17 children were successfully reset immediately, and 2 children were successfully reset again. The average fixed time was (25.00±3.35) days. At 6 months of follow up, 12 patients got excellent results, 3 good, 2 fair, and 0 poor according to Anderson forearm function evaluation criteria. The position of all children were larger than 3/4, and 10 children were received anatomical reduction, alignment of 4 children was less than 10°, 3 children was less than 15°. No complications such as fracture displacement, nonunion, compartment syndrome, and forearm rotation dysfunction occurred. CONCLUSION Restoration of distal radius double fracture in children with the combination of the closed folding and top fixation maneuver and splint fixation maneuver has advantages of higher success rate, lower complications, which could reduce operating difficultyand pain of patients.

Chinese patent medicines(CPMs) are unique therapeutic drugs in China. Establishing and improving the evaluation criteria is an important measure to promote the high-quality development of CPMs. Based on the "evaluation criteria of high-grade CPMs with quality as the core index" established by our group in 2018, the "high-quality evaluation criteria for CPMs based on whole process control" was proposed in the present study in 2022. The scope of application and basic principles of the new criteria were clarified. A quality evaluation scoring table was established in the new criteria, including five parts: raw material selection, production process, quality control, efficacy evaluation, and brand building. The technical evaluation indexes involved have increased from 20% in the original criteria to 70% in the new criteria, and efficacy evaluation has been added in the new criteria. The subjective evaluation indicators account for a large proportion in the original criteria, which is prone to bias. The improved criteria overcome this shortcoming. It is expected that the new criteria as a basis can play a better role in the selection of high-quality products of CPMs, guide enterprises and institutions to participate actively in the evaluation and research of high-quality CPMs, and promote the high-quality development of CPMs.
