A total of 35 patients with hallus valgus (56 feet) received treatment at the Department of Orthopedics, the Sixth People's Hospital, Shanghai Jiao Tong University between January 2004 and June 2005 and were recruited into this study. These patients underwent osteotomy of proximal first metatarsal and internal fixation with poly (L-lactic acid) (PLLA) absorbable pins. All patients were followed up for 4-22 months. Excellent outcomes were found in 27 patients (44 feet) and good results in 8 patients (12 feet). The mean healing time of surgical region was 6 weeks, nonunion or delayed union was not found. There were 3 cases suffering from complications post surgery. Two of them presented with peripheral wound red swelling, considering as a result of extraneous material-caused aseptic inflammatory reaction. This phenomenon would be regressed 2-4 weeks after hydropathic compress of ethanol gauzes and timely renewal of dressings. There was 1 case who suffered from protrution of absorbable pin 1 week after fixation and received reposition and plaster fixation. Bone displacement and nonunion were not found. This complication maybe results from excessively large bone pore due to shaking of electrodrill, which leads to loosening of absorbable pins.

Objective To observe the final adult height (FAH) outcome and influencing factors in Turner′s Syndrome(TS) children treated with recombinant human growth hormone ( rhGH ).Methods Thirty TS children treated with rhGH were compared with 16 TS children without rhGH treatment and were followed up to achieve their FAH.Comparisons were made regarding predicted adult height (PAH),height standard deviation score for chronological age( HtSDScA ),height SDS for BA( HtSDSRA ),and growth velocity ( GV ) between rhGH treatment and without treatment groups and between the onset and by the end of rhGH treatment group.The factors determining FAH were also evaluated.Results FAH in rhGH treatment group was obviously improved as compared with untreatment group[ ( 149.5±6.3 vs 142.4±5.2) cm,P<0.01 ].FAH in treatment group was positively correlated with height standard deviation score for chronological age ( Ht0 SDSCA ),Hto SDS for BA ( Hto SDSBA ),height age ( HA0 ) at preliminary diagnosis,and correlated with duration of rhGH therapy,duration of estrogen-free rhGH therapy,and PAH0SDS at preliminary diagnosis.Stepwise regression analysis indicated that duration of estrogen-free rhGH therapy and PAH0 SDS were the variables with the greatest identified influence on FAH (F =11.56 and F =86.91,P< 0.01 ).FAH in the 45,XO group was significantly different from the mosaicism group (45,XO/46,XX ) [ ( 147.2 ± 6.3 vs 153.3±6.4) cm,P =0.038].Conclusion rhGH treatment is efficacious in improving FAH of TS children,but a variability in the magnitude of the response to rhGH is recognized.Duration of estrogen-free rhGH therapy and PAH0SDS are the variables with the greatest identified influence on FAH,and karyotype may be one of the influence factors.rhGH treatment should be initiated as early as possible and sufficient course of estrogen-free rhGH therapy is needed to yield a satisfactory FAH.

Objective:To evaluate the diagnostic value of hydrogen sulfide breath test(SBT) for small intestinal bacterial overgrowth (SIBO).Methods:College students were enrolled to complete gastrointestinal symptom scale, food frequency questionnaire, lactulose hydrogen- methane breath test (LHMBT) and SBT. Based on the correlation between hydrogen sulfide(H 2S) and hydrogen or methane gas,the receiver operating characteristic (ROC) curve of H 2S was drawn and diagnostic criteria of SBT was defined. Results:A total of 300 subjects including 84 males and 216 females with age 17-32 (21.6±2.4) years were enrolled from April 2019 to December 2019 and divided into two groups.Two hundred and three patients reported SIBO discomforts with 99 (48.8%) LHMBT positive, while 38 (39.2%) were LHMBT positive in 97 health controls. Rise of H 2S at 90 min was positively related with that of hydrogen ( r=0.516, P<0.01), and H 2S levels at 90 min were positively correlated with methane ( r=0.632, P<0.01). A rise in H 2S of ≥25.0 ppb or H 2S levels ≥62.5 ppb at 90 min during lactulose breath test was considered positive for SIBO, that sensitivity, specificity and accuracy were 66.4%,79.1% and 73.3% respectively. H 2S levels were significantly related to the amount of Vitamin B 12 intake ( P=0.011). H 2S-positive subjects exhibited a constipation-predominant pattern. Conclusion:SBT is consistent with LHMBT, especially in constipation-predominant patients, which may provide a reference to the diagnosis of SIBO.
