Objective To guide bracing treatment for adolescent idiopathic scoliosis (AIS). Methods A total of 68 AIS patients with apex vertebrae (AV) under T6 had received the improved Cheneau bracing treatment between March 2008 and June 2010. All patients were divided into two groups. There were 16males and 35 females, with a mean age of 13.6 years (range, 10.6-17.2) in the intervention group. The mean Cobb angle was 29.5° (range, 20°-38°); Risser sign was 2-4; Vertebralrotation degree was 0-2 in the group;while there were 6 males and 11 females, with a mean of 13.2 years (range, 10.8-16.8) in the control group.The mean Cobb angle was 28.7° (range, 20°-37°); Risser sign was 2-4; Vertebralrotation degree was 0-2 in the control group. All patients in control group were informed standardized bracing treatment method. But we gave patients in intervention group two copies of "The Form of Guiding Bracing Treatment" treatment of patients with AIS, and informed that they carried out the bracing treatment according requirement of the form.Cobb angle was measured before the treatment and at 6th, 12th, 18th month after treatment. Results Sixtyfive cases were followed up for 18-27 months. However, one female in control group and two females in intervention group were lost during follow-up. Coefficient and intraclass correlation coefficient of form were both over 0.60. The acceptance rate of the table was 97.54%(199/204), qualified rate was 100.00%( 199/199), and with good content validity. The mean Cobb angle decreased gradually from 28.71° to 25.76° in control group and from 29.47° to 21.59° in intervention group. Four cases in control group and 34 cases in intervention group had reduced more than 5° at 18 months after treatment. There was significant difference regarding Cobb angle between two group. Conclusion The form of guiding bracing treatment has good reliability and validity and can guide bracing treatment of AIS correctly and effectively.

Objective To investigate the signal transduction pathway mechanisms of rats with liver fibrosis regulated by leptin and interfering effects of mistletoe alkali .Methods The hepatic fibrosis in rats model was established by injecting carbon tetrachloride .Forty-five SD rats were randomly divided into normal group ,model group and therapeutic group.All rats except rats in normal group were intraperitoneally injected with 40%carbon tetrachloride in peanut oil with a dose of 2.0 mL/100g according to the body weight twice a week for 8 weeks.Then, the therapeutic group was given mistletoe alkali (8g/(kg· d)) for 8 weeks via gastrogavage.Rats in normal and model group were served with distilled water at the same time.At the end of the 16th week, blood and tissue specimens were taken from all the rats .The influence of mistletoe alkali on liver morphology in liver fibrosis rat model was reviewed by HE and Masson staining .The effects of mistletoe alkali on the expression of Leptin and its receptor ( OB-Rb ) in HSC in fibrosis rat model were determined by immunohistochemistry (IH).The expression of JAK2, STAT3 and the activity of phospho -JAK2, phospho-STAT3 were detected by Western blotting analysis .Results The degree of fibrosis of the model group was more severe than the normal group and the treatment group , which suggested that mistletoe alkali can reverse liver fibrosis in rats . Immunohistochemical staining showed that mistletoe alkali reduced the hepatic expression of leptin and OB -Rb in rats with liver fibrosis in comparison with their expression in the model group .Compared with the normal group , the expression of JAK2 and STAT3 increased in the model group .However, the expression of JAK2 and STAT3 decreased in the medication groups compared with the model group .Conclusion Mistletoe alkali can effectively ameliorate liver fibrosis in rats possibly through inhibiting hepatic leptin and its receptor expressions , which through inhibiting hepatic leptin and its receptor expressions , thus inhibit the JAK2/STAT3 signaling pathway .

OBJECTIVETo evaluate clinical outcomes of anterior cruciate ligament (ACL) and posterior cruciate ligament (PCL) reconstruction under arthroscopy and repair of the injured posteromedial complex structure of the knee joint in the treatment of posterolateral knee dislocation with multiple ligament injuries.

METHODSFrom March 2008 to August 2012,22 patients (16 males and 6 females, ranging in age from 20 to 53 years old, with an average of 30.5 years old) with posterolateral dislocation of the knee were treated with primary reconstruction of ACL and PCL, combined with the repair of injuries in the posteromedial complex and soft-tissue. Eight patients had injuries caused by sports,5 patients road accidents and 9 patients falling down. The ACL was reconstructed using the gracilis and semitendinosus tendons. The PCL was reconstructed using LARS artificial ligaments (14 cases), or gracilis and semitendinosus tendons (8 cases). Suture repair was performed in 17 patients with posteromedial ligament injuries,and self-semitendinosus strengthening operations were performed in 5 patients. Continuouspassive montion (CPM) and active exercises were executed after operation at early stage. The IKDC and Lysholm system were used to evaluate therapeutic effects.

RESULTSAll the patients were regularly followed up, and the duration ranged from 11 to 56 months (averaged, 39 months). According to the IKDC scale,9 patients got a grade A result, 10 got a grade B result, and 3 got a grade C result. The IKDC subject score was 89.6±3.1 and the Lysholm scores was 90.7±1.8 at the latest follow-up, which were both better than those before operation.

CONCLUSIONReconstructing the ACL and PCL and repairing injured posteromedial complex of the knee followed by an active rehabilitation is an effective method to treat posterolateral knee dislocation.

Objective To study the clinical efficacy of bilateral double Z plasties for correction of the webbed neck defects, and to explore its principle and superiority to other reported methods. Methods We designed a small Z plasty over the mastoid with a rhomboidal skin resection of infra-hairline, and another large Z plasty transposition skin flap in superior-acromion. The tight band of fibrous webbing was separately cut and undermined at infra-mastoid and midclavicular line, wherein the middle part of the band retracted medially.Results It involved narrow tunneled anterolateral skin undermining and minimal skin resections from the nape of the neck, and posterior rhomboidal skin excision avoided the unnatural and noticeable lateral scars with normal skin extended in the middle of the webbing.The resultant scar was hidden and mild with no hypertrophic scars. A total of 5 cases were repaired, in which 1 case was male, 4 others were females. Follow-up for 1 to 11 years showed that the appearance and function in the repaired sites by using the bilateral double Z-plasties for repair of webbed neck deformity were very satisfactory. Conclusion We propose the use of this technique for correction of webbed neck deformities with simplified manipulation and cosmetic effect.
