BACKGROUND:Because the geographical environment and diet cause obesity and osteoarthritis in Xinjiang Uygur local patients, the number of patients became more. At present, more and more patients received artificial knee replacement. How to master and further apply the technology of soft tissue balance during artificial knee replacement in patients of different physical fitness and nations becomes the focus of many scholars. OBJECTIVE:To analyze the clinical efficacy of soft tissue balance in Xinjiang Uygur patients with knee valgus in total knee replacement. METHODS:A total of 60 cases (72 knees) with severe knee osteoarthritis with a certain degree of knee valgus were subjected to total knee replacement through anterior lateral approach and individualized soft tissue balance from February 2009 to December 2010. Folow-up mode was the clinic visit. X-ray was used to measure tibiofemoral angle (i.e., the supplementary angle of the included angle between anatomic axis of femur and tibia). Clinical score and functional score of American knee society knee score were applied to assess knee joint function. RESULTS AND CONCLUSION:A total of 57 patients were folowed up for 6-35 months. The tibiofemoral angle decreased from 27.9° preoperatively to 5.6° postoperatively. Clinical score of American knee society knee score elevated from 16.7 points preoperatively to 87.5 postoperatively. Functional score of American knee society knee score elevated from 7.9 points preoperatively to 85.2 postoperatively. Significant differences in preoperative and final folow-up scores were detected (P < 0.01). Valgus deformity was corrected and joint stability was good in 57 patients after replacement. These findings indicate that in patients with severe knee osteoarthritis and valgus deformity, to select individualized treatment of soft tissue balance can effectively correct soft tissue imbalance and get more satisfactory clinical results.

Abstract? AIM: To evaluate the efficiency of two different operation ways, vitrectomy and vitrectomy combined with inferior scleral buckling, for a complex kind of retinal detachment.?METHODS:The complex kind of retinal detachment were diagnosed in 100 cases ( 100 eyes ) , with the common features:1)the course of more than 1mo;2) at least one retinal hole located in the inferior marginal retina;3) the detachment of retina was found proliferated, there was at least 1 retinal fold in retinal detachment area. The patients were randomly divided into two groups: the treatment group ( 50 eyes ) who received vitrectomy combined with inferior scleral buckling;the control group ( 50 eyes ) who received vitrectomy without scleral buckling. The retinal anatomic reattachment, visual function recovery, macular central fovea thickness and complications in two groups were observed.? RESULTS: There were 49 eyes ( 98%) with retinal anatomic reattachment in the treatment group while 42 eyes(84%)in control group(χ2=4.2605, P<0.05);the best corrected visual acuity ( BCVA) was 0.254 ±0.238 in the treatment group while it was 0.219±0.229 in control group (t=1.8879,P>0.05);the macular central fovea thickness was 272 ±32.21μm in the treat group while it was 316 ± 33.46μm(t=12.597,P<0.01).Intraocular pressure in 12 eyes ( 24%) was more than 30mmHg in the treatment group while 4 eyes ( 8%) in control group within 1wk postoperation (χ2=4.7619,P<0.05); intraocular pressure in 100 eyes were controlled below 21mmHg 1mo postoperatively.? CONCLUSION: It is a more effective method to vitrectomy combined with inferior scleral buckling than the single vitrectomy for the special kind of retinal detachment.It can increase the rate of retinal anatomic reattachment and reduce macular edema.

Objective To explore the surgical techniques and effects of one-stage reconstruction surgery for pediatric comminuted and depressed fractures of frontal bone and anterior skull base.Methods The clinical data of 13 pediatric cases with one-stage reconstruction surgery for comminuted and depressed fractures of the frontal bone and anterior skull base were reviewed retrospectively,including 8 male and 5 female,aged from 4 to 14 years,with a mean age of 8 years.Admission Glasgow Coma Scale (GCS) was as follows:3 to 8 scores in 2 cases,9 to 11 scores in 4 cases,and 12 to 15 scores in 7 cases.The intraoperative one-stage osseous and vascular pedicle membranous reconstruction of frontal bone and anterior skull base had been performed in all patients.The periosteum-bone fragments-periosteum had been used in 4 cases whose bony defect diameter of anterior cranial fossa was over 1 cm,multimodality therapy were carried out postoperatively.The follow-ups were regularly executed after discharge.Results GCS at discharge was as follows:3 to 8 scores in 1 case,9 to 11 scores in 2 cases,and 12 to 15 scores in 10 cases.No significant difference was found in GCS between those on admission and at discharge(χ2=3.02,P>0.05).Eleven cases had a phenomenon of nasal hemorrhage and the duration was not exceeding 48 hours.No intracranial infection and cerebrospinal fluid leakage occurred in all patients.All patients received an acceptable appearance without obvious frontal depre-ssion or proptosis.Postoperative computed tomography image showed normal cranial volume,well reset of fracture pieces,no fracture pieces existing in intracerebral tissue,satisfactory hematoma evacuation,and orbital contents without compression.The complications like cerebrospinal fluid leakage,poor incision healing,brain abscess or mucous cyst had not been found in all patients from 3 months to 6 years follow-up period.Conclusions The one-stage reconstruction surgery for pediatric comminuted and depressed fractures of frontal bone and anterior skull base suggests a better prognosis,effectively less complications,which helps to avoid secondary surgery,but regular follow-ups are absolutely necessary.This procedure is worth applying and spreading to pediatric patients and medical institutions if necessary.

Objective:To analyze the concerning guarantee mechanisms during the transformation of the com-munity health service mode. Method:Purposive sampling was adopted. Twelve community health service centers in Beijing, Shanghai, Zhengzhou, and Chengdu, where the transformation of the community health service mode was pi-loted earlier and representative, were selected as the field survey sites. The qualitative method was used to collect da-ta accompanied by the quantitative method. Results: The guarantee mechanisms related to the transformation of the community health service mode could be concluded into four main types:collaboration mechanism, health profession-al training mechanism, incentive mechanism, and policy guarantee mechanism. All of the four mechanisms contribu-ted to the improvement of general teamwork, dual referral systems, and the development of contract and appointment services. Conclusion:During the transformation of the community health service mode, priority strategies include top-down design, health professional training mechanisms, and performance-based incentive mechanism, all of which should be implemented in the future.
