Background:The clinical outcome of transtrochanteric rotational osteotomy (TRO) for osteonecrosis of the femoral head (ONFH) remains controversial,and the promising clinical results of several Japanese studies could not be reproduced in American and European studies.Trying to solve controversies on TRO for ONFH rising from apparently conflicting studies,a meta-analysis was conducted to assess the 5-and 10-year hip survival rates (with conversion to artificial joint replacement and radiographic failure as endpoints) after TRO.Methods:All eligible studies were searched in seven comprehensive databases including PubMed,Web of Science,Embase,Cochrane Library,VIP Database,China Knowledge Resource Integrated Database,and Wan Fang Database prior to June 2019.The outcomes evaluated were 5-and 10-year hip survival rates after TRO.The odds ratio and risk difference for the non-comparative binary data with the 95% confidence intervals (CIs) were calculated for each outcome.The included studies were assessed for methodologic bias and potential reasons for heterogeneity were explored.Results:Nineteen studies of TRO for ONFH were eligible for this meta-analysis according to inclusion criteria.Based on the previous report,two calculation methods (Methods 1 and 2) were adopted in this meta-analysis.Furthermore,we performed a subgroup analysis of the 5-and 10-year hip survival rates (Method 1) after TRO for ONFH:Asian sub-population and non-Asian subpopulation.Taking conversion to artificial joint replacement as the endpoint,5-and 10-year hip survival rates (Method 1) after TRO for ONFH in the Asian population were 0.86 (95% CI =0.82-0.89) and 0.72 (95% CI =0.65-0.78),respectively,and 5-and 10-year hip survival rates after TRO for ONFH in the non-Asian population were 0.55 (95% CI =0.43-0.67) and 0.42 (95% CI =0.28-0.55),respectively.The 5-and 10-year hip survival rates (Method 2) after TRO for ONFH were 0.90 (95% CI =0.79-0.95) and 0.89 (95% CI =0.81-0.94),respectively.Taking radiographic failure as the endpoint,5-and 10-year hip survival rates after TRO for ONFH were 0.70 (95% CI =0.64-0.76) and 0.53 (95% CI =0.46-0.61),respectively.Conclusions:The 5-and 10-year hip survival rates after TRO for ONFH were satisfactory in the Asian population,and were acceptable in the non-Asian population despite high early failure rates.

OBJECTIVETo evaluate clinical effect and safety of floating needle therapy and duloxetine in treating patients with persistent somatoform pain disorder (PSPD).
METHODSTotally 108 PSPD patients were randomly assigned to the floating needle treatment group, the duloxetine treatment group, and the placebo treatment group, 36 in each group. Patients in the floating needle treatment group received floating needle therapy and placebo. Those in the duloxetine treatment group received duloxetine and simulated floating needle therapy. Those in the placebo treatment group received the placebo and simulated floating needle therapy. All treatment lasted for six weeks. Efficacy and adverse reactions were evaluated using Simple McGill pain scale (SF-MPQ) and Treatment Emergent Symptom Scale (TESS) before treatment and immediately after treatment, as well as at the end of 1st, 2nd, 4th, and 6th week of treatment, respectively. Hamilton Depression Scale (HAMD, 17 items), Hamilton Anxiety Scale (HAMA) were assessed before treatment and at the end of 1st, 2nd, 4th, and 6th week of treatment, respectively. Patients in the floating needle treatment group and the duloxetine treatment group with the total reducing score rate of SF-MPQ in Pain Rating index (PRI) ≥ 50% after 6 weeks' treatment were involved in the follow-up study.
RESULTS(1) Compared with the same group before treatment, SF-MPQ score, HAMD score and HAMA total scores all decreased in all the three groups at the end of 1st, 2nd, 4th, and 6th week of treatment (P < 0.05, P < 0.01). Besides , each item of SF-MPQ significantly decreased immediately after treatment in the floating needle treatment group (P < 0.01). Compared with the placebo treatment group, SF-MPQ, HAMD, and HAMA total score in the floating needle treatment group significantly decreased after 1, 2, 4, and 6 weeks of treatment (P < 0.05, P < 0.01). SF-MPQ score, HAMD score and HAMA total score in the duloxetine treatment group also significantly decreased after 2, 4, and 6 weeks of treatment (P < 0.05, P < 0.01). (2) There were 3 patients (8.3%) who had adverse reactions in the floating needle treatment group, 17 (50.0%) in the duloxetine treatment group, and 7 (21.2%) in the placebo treatment group. Compared with the placebo treatment group, the incidence of adverse reaction increased in the duloxetine treatment group (χ² = 6.04, P < 0.05). Besides, it was higher in the duloxetine treatment group than in the floating needle treatment group (χ² = 14.9, P < 0.05). (3) There were 19 patients in the floating needle treatment group and 17 patients in the duloxetine treatment group involved in the follow-up study. Compared with 6 weeks after treatment, no significant difference was observed at 3 and 6 months after treatment in the score of SF-MPQ, HAMD, and HAMA in the floating needle treatment group and the duloxetine treatment group. No significant difference was observed between the two groups (P > 0.05). There were 5 patients (29.4%) who had adverse reactions in the duloxetine treatment group, and no adverse reactions were observed in the floating needle treatment group. The adverse reaction rate was significantly different between the two groups (χ² = 4.26, P < 0.05).
CONCLUSIONSFloating needle therapy and duloxetine were effective in treatment of patients with PSPD. However, floating needle therapy could relieve pain more rapidly than duloxetine, with obviously less adverse reactions.

BACKGROUNDMutations in PAX6 gene have been shown to be the genetic cause of aniridia, which is a severe panocular eye disease characterised by iris hypoplasia. However, there is no study to do genetic analysis of aniridia, although there are several case reports in China. Here, we describe a mutation analysis of PAX6 in a large Chinese family with aniridia.
METHODSGenomic DNA from venous blood samples was prepared. Haplotype analysis was performed with two genetic markers (D11S904 and D11S935). Fourteen exons of the PAX6 gene were amplified from genomic DNA. Polymerase chain reaction (PCR) products of each exon were analysed by single strand conformational polymorphism (SSCP). The PCR products having an abnormal pattern were sequenced to confirm the mutation.
RESULTSSignificant evidence for allele sharing in affected patients was detected suggesting that PAX6 mutation links to aniridia in this family. An extra band corresponding to exon 9 in PAX6 was found by single strand conformational polymorphism analysis in all the aniridia patients in this family, but not detected in the unaffected members. A mutation of C to T was detected by sequencing at the nucleotide 1080 that converts the Arg codon (CGA) to the termination codon (TGA).
CONCLUSIONSAniridia is caused by a nonsense mutation of PAX6 gene in the large Chinese kindred. Genetic test is important to prevent the transmission of aniridia to their offsprings in the kindred by prenatal diagnosis.

OBJECTIVETo evaluate the toxicity of chicken calamus keratin (CCK) conduit as a tissue-engineered scaffold material.
METHODSThe chemical composition of the leaching solution of CCK was determined by means of ultraviolet spectrometry, and the toxic effects of the solution was evaluated by skin sensitization test in rats, intracutaneous stimulation test in rabbits, acute systemic toxicity test in mice, and cytotoxicity test in L929 cells.
RESULTSThe leaching solution of CCK consisted mainly of middle-molecular-weight peptides with a small quantity of macromolecular proteins. Skin sensitization test in rats showed that application of the CCK leaching solution caused no obvious skin reddening, regional edema, or skin necrosis. Intracutaneous injection of the leaching solution in rabbits did not induce obvious skin stimulation manifested by intradermal erythema or edema. In acute systemic toxic test, administration of the leaching solution in mice caused no death, organ dysfunction, cyanosis, tremor, severe peritoneal irritation, ptosis, or dyspnoea. In vitro cytotoxicity test indicated that the cell toxicity of the CCK leaching solution was approximately at 0 level.
CONCLUSIONCCK contained in the treated chicken calamus easily undergoes hydrolysis to release mainly some peptides which do not induce obvious toxic effects, suggesting the safe potential applications of CCK conduit as a tissue-engineering biomaterial.

To evaluate the effects of glutamine-supplemented parenteral nutrition (PN) and probiotics in adult autoimmune enteropathy (AIE) patients. Four adult AIE patients were identified from April 2006 to January 2012. Clinical and nutritional data were obtained from the patients' medical records. Glutamine-supplemented PN started immediately when the AIE diagnosis was confirmed. The total PN duration was 351 days. According to the PN prescription, the average caloric intake ranged from 20 to 25 kcal/kg/day, and the protein intake ranged from 1.2 to 1.5 g/kg/day. Alanyl-glutamine (20 g/day) was administered to AIE patients for 4 weeks followed by a 2-week break, and this treatment schedule was repeated when PN lasted for more than 6 weeks. Body weight gain and an increased serum albumin level were achieved after PN, and defecation frequency and quality also improved. Each patient received oral supplements, 250 mL of Ensure and two probiotics capsules (each capsule containing 0.5x10(8) colonies) three times a day when enteral nutrition started. Three AIE patients were successfully weaned off PN, and one patient died of pneumonia. Glutamine-supplemented PN and probiotics show promise in managing patients with AIE and related malnutrition.
