Objective:To establish a new method of designing and fabricating a facial simulation model of infant cleft lip for lip repair simulation and surgery teaching. Methods: Using latest three-dimensional scanning, reversed engineering and rapid prototyping techniques to fulfill the individual design and rapid auto-manufacture for the facial model of the cleft lip infants. With the new chromatosis technique and special silicone material of Maxillofacial Prosthetics the simulative face of infant cleft lip were fabricated. The new simulation model was used for lip repair surgery teaching. Results: The vivid faical data was successfully acquired by scanner and then designed by software. The solid plastic partern of patient's face was fabricated by machine, which was eventually replaced by maxillofaical silicon. The surgeon applied it for pre-surgery simulation and surgery teaching. Conclusion: This study successfully designed and fabricated the new simulation model of cleft lip infant's face, which can be a ideal training model for lip repair surgery teaching.

Objective:To analyze the reasons for unplanned resection of soft tissue sarcomas and explore the treatment strategies for cancer surgery. Methods: The study included 105 patients with soft tissue sarcomas admitted to the First Affiliated Hospital of Xinjiang Medical University between October 2009 and December 2012. The average age of the patients was 52 years old. Among the patients, 65 were males and 40 were females. Up to 82 patients underwent planned resection (Group A) in our hospital, and 23 underwent unplanned resection (Group B) in other hospitals. Wide excision and radical resection were conducted in Group A, whereas extended resection was performed in Group B. General data, tumor location and size, resection margin, local recurrence and metastasis, and survival were statistically analyzed in the two groups. Results:The proportion attaining the margin of wide excision was obviously lower in Group A than in Group B (P＜0.05). The 3-year survival rate was significantly higher in Group B than in Group A (P=0.001). Within an average follow-up of 18 months (3 months to 36 months) in Group B, 12 patients died, including 9 with tumor metastasis and 3 with other diseases. Within an average follow-up of 23 months (5 months to 36 months) in Group A, 15 patients died, including 12 with tumor metastasis and 3 with other diseases. Conclusion:Compared with planned surgical operation, unplanned resection of soft tissue sarcomas often leads to inadequate resection margin, which results in a high incidence of local recurrence and an increased mortality. Thus, clinicians should attempt to avoid unplanned resection of sarcomas.

Objective:To analyze the clinical effect of different surgical methods on giant-cell tumor of bone (GCTB). Methods:Between January 2007 and June 2012, 37 patients receiving treatment for GCTB were enrolled in this study. These patients included 20 males and 17 females whose ages ranged from 20 to 56 (average=31.6). The prosthesis replacement and nonprosthetic replacement op-eration on the postoperative recurrence, limb function, comprehensive evaluation of the curative effect, as well as morbidity and recur-rence rate among different nations and in the upper and lower limbs of GCTB patients were analyzed. Results:The predilection age of the cases ranged from 20 to 50 years old. The incidence was higher in the Uighur population of Xinjiang, China. However, the recur-rence rate in ethnic difference was not statistically significant (P>0.05). Conclusion:The predilection age of GCTB cases was 20~50 years old, with higher morbidity in Uighur than in Han and other ethnic groups. The morbidity and recurrence rate were higher in the lower limbs than in the upper limbs of patients. The scraping bone graft and bone cement filling, the internal fixation of the scraping bone graft, and the artificial joint replacement of tumor resection were all reliable modes of treatment.

OBJECTIVETo observe the clinical effect of chronic fatigue syndrome (CFS) treated with moxibustion at Gaohuang (BL 43).

METHODSWith stratified block randomization, 72 patients accorded with inclusive criteria were divided into a moxibustion at Gaohuang (BL 43) group (moxibustion group) and an acupuncture group, 36 cases in each one. In the moxibustion group, Gaohuang (BL 43) was treated with big moxa cones as the main acupoint, 10 cones a time; Qihai (CV 6) and Zusanli (ST 36) were added with big moxa cones, 7 cones a time. In the acupuncture group, acupoints were the same as those in the moxibustion group, and twirling reinforcing method was used after qi arriving, 60 times one minute and 360° with range. In the two groups, 10-day treatment was made into one course and there were two days between courses. The treatment was given once a day for 3 courses. Changes of fatigue assessment index (FAI) before and after treatment and clinical effects were observed.

RESULTSThe total effective rate was 88.9% (32/36) in the moxibustion group, which was better than 72.2% (26/36) in the acupuncture group apparently (P < 0.05). After treatment in the two groups, FAI scores were obviously declined compared with those before treatment (both P < 0.01) and FAI score in the moxibustion group was apparently lower than that in the acupuncture group (P < 0.05).

CONCLUSIONMoxibustion at Gaohuang (BL 43) can improve the FAI score of patients with CFS and the clinical efficacy is definite.

Objective To construct recombinant adenovirus vector containing mouse CD40Ig fusion gene for the study of induction of donor-specific tolerance. Methods CD40Ig fusion gene was constructed by PCR overlapping technique, and was cloned into the shuttle plasmid pAdTtrack-CMV. The linearized shuttle plasmid was co-transfected into the E.coli strain BJ5183 with bone plasmid pAdeasy1, then the recombinant adenovirus plasmid was generated. The adenovirus was packaged and amplified in Cells 293. Results The recombinant virus AdCD40Ig was successfully constructed and its titer was 5?109 efu/ml. Conclusion AdCD40Ig can be used as an agent in experiment to induce donor-specific tolerance.

Objective To access the long-term efficacy and safety of immunosuppression on the progression of IgA nephropathy (IgAN) by Meta analysis.Methods Databases EMBASE,Pubmed,Elsevier Science Direct,Scopus,Web of Science,Google Scholar,Cochrane Library,China National Knowledge Infrastructure,WanFang and VIP Data were retrieved to collect the randomized controlled trials (RCTs) at least 3 years follow-up on immunosuppression for IgAN published before May 2014.The literatures were screened independently by two reviewers according to the inclusion and exclusion criteria,and the methodological quality was assessed.Statistic software Stata 12.0 was used to conduct analysis.Results Nine articles were included in this study with a total of 568 patients.Immurnosuppression could lowered the risk for the progression to ESRD (RR=0.32,95％CI:0.20-0.49,P ＜ 0.01).As far as the efficacy of immunosuppression,subgroup analysis indicated that three studies with more than 7 year follow-up (RR=0.28,95％CI:0.13-0.59,P ＜ 0.01) were similar with 7 studies followed by for less than 7 years (RR=0.34,95％ CI:0.19-0.59,P＜0.01); six adopted immunosuppressor monotherapy (RR=0.29,95％ CI:0.15-0.58,P＜ 0.01) were similar to two used corticosteroids plus other immunosuppression (RR=0.33,95％CI:0.18-0.59,P ＜ 0.01); There were no significant differences between four studies from Europe (RR=0.27,95％CI:0.14-0.53,P ＜ 0.01) and five from Asia (RR=0.35,95％ CI:0.19-0.65,P＜0.01).Immunosuppression was associated with an increased risk for adverse events (RR=2.33,95％ CI:1.33-4.09,P＜0.01).Conclusion Immunosuppression for IgAN may reduce long-term risk of progression to ESRD,but increase the risk of adverse events to some extent.

Objective To evaluate the effect of unipolar versus bipolar hemiarthroplasty for treatment of femoral neck fracture in the elderly Methods Related randomized controlled trials (RCTs) and quasi-randomized controlled trials (qRCTs) were searched from computerized databases MEDLINE,EMBASE,Cochrane Library,and CBM disc.Additional studies were identified through hand searches of 10 domestic journals.Time period of the search was from 1966 to June 2012.RevMan 4.2.8 software was used for data analysis.Results A total of 7 RCTs and 3 qRCTs were included.In this meta analysis,bipolar hemiarthroplasty was associated with better hip function compared with unipolar hemiarthroplasty at postoperative 6 months (RR =0.74,95％ CI0.62-0.88,P ＜ 0.01).However,the two procedures revealed no significant differences in terms of postoperative one-year dislocation rate (RR =1.01,95％ CI0.54-1.89,P ＞ 0.05),reoperation rate (RR =1.13,95％ CI 0.74-1.72,P ＞ 0.05),major complication incidence (except for dislocation) (RR =1.27,95％ CI 0.74-2.18,P ＞ 0.05),and postoperative 2-year mortality (RR1.16,95％ CI 0.73-1.87,P ＞ 0.05).Conclusion Bipolar hemiarthroplasty is preferable to unipolar hemiarthroplasty for hip function improvement,but postoperative one-year dislocation rate,reoperation rate,major complication incidence (except for dislocation),and postoperative twoyear mortality are similar for the two procedures.
