Objective To investigate the efficacy of sorafenib alone or combination with transarterial chemoembolization(TACE)and percutaneous local cryotherapy(PLCT)for advanced hepatocellular carcinoma patients without operation opportunity. Methods Sixty-four advanced hepatocellular carcinoma patients were selected as our subjects,who were underwent treatment of sorafenib alone or combination with TACE and PLCT. Thirty-two cases with sorafenib therapy were served as sorafenib group and another 32 cases with sorafenib in combination with transarterial chemoembolization and PLCT were served as combination group. All patients were followed up for 6 - 32 months. The treatment efficacy and tumor development were recorded. Results All surgeries of the patients were succeed and no death or serious operation complications occurred. Of 64 patients, 11 were achieved a complete remission( CR),31 cases with partial remission( PR),14 cases with stable development(SD),and 8 cases with progressive disease(PD). In the sorafenib group,3 cases were with CR,11 patients with PR,12 with SD,and 6 patients with PD. In the combination group,8 patients were with CR,20 patients with PR,2 patients with SD and 2 patients with PD,and the difference was significant between the two groups(χ2 = 14. 028,P = 0. 003). The median periods to tumor progression were 20 and 53 weeks in the sorafenib group and the combination group,and the difference was significant( χ2 = 14. 773,P = 0. 000). Conclusion For hepatocellular carcinoma patients without operation opportunity,sorafenib combined with TACE and PLCT can increase the tumor remission rate and prolong the periods to tumor progression in patients with hepatocellular carcinoma.

BACKGROUND:Total knee arthroplasty for knee osteoarthritis accompanied with extra-articular deformity is stil chal enging. An individual replacement plan should be designed to obtain good mechanical axis and to recover suitable soft-tissue balance. OBJECTIVE:To observe the safety and feasibility of individual y designed one-stage total knee arthroplasty for knee osteoarthritis combined with ipsilateral femoral extra-articular deformity. METHODS:A total of eight patients with knee osteoarthritis combined with ipsilateral femoral extra-articular deformity were enrol ed in this study. According to preoperative plan, five patients underwent intra-articular compensatory osteotomy, and the remaining three received extra-articular corrective osteotomy. Multi-planar deformities as wel as soft-tissue conditions were recorded. Main outcome measures included the hospital for special surgery score, Western Ontario and McMaster Universities Arthritis Index score and alignments deviation. RESULTS AND CONCLUSION:The patients were averagely fol owed up for 29 months. The hospital for special surgery score changed from preoperative 32.5 points to postoperative 87.5 points. The Western Ontario and McMaster Universities Arthritis Index score was increased from preoperative 37.1 points to postoperative 88.8 points (P<0.05). Mean mechanical axis deviation (either varus or valgus) changed from preoperative 17.1° to postoperative 1.4° (P<0.05). Al cases with extra-articular corrective osteotomy healed within 3 months, and none had postoperative infection, loosening or venous thromboembolic events. One patient was with 5° residual knee anti-sheets. Results verified that one-stage total knee arthroplasty procedures are effective in the treatment of knee osteoarthritis accompanied with ipsilateral femoral extra-articular deformity in accordance with individual preoperative plan.

Objective To determine the prevalence of latex glove(LG)-induced type Ⅳ hypersensitivity in clinical nurses. Methods 100 clinical nurses were selected,among whom 69 nurses were set as the latex glove hypersensitivity group,and the other 31 nurses did not show hypersensitivity to latex glove (the control group).The two groupe underwent a patch testing with a modified European standard series of allergens supplied by Chemotechnique Diagnostics.The positive allergens were compared between the two groups. Results The positive rate of patch testing in patients of the latex glove hypersensitivity group was superior to that in the control group (73.9％ vs 25.8％).Cobalt chloride and potassium dichromate were the most common allergens in both groups,while only formaldehyde and para-phenylenediamine were more susceptible in the latex glove hypersensitivity group compared with that in the control group.26.1％ of the latex glove hypersensitivity group was responsive to rubber additives,but in the control group the results were negative.Conclusions The hand dermatitis of female nurses with LG allergy is mainly caused by exposure to daily necessities.The prevalence of LG-induced type Ⅳ hypenensitivity is relatively high in clinical murses.

BACKGROUND:Currently, the study of total hip arthroplasty in elderly is more. Perioperative treatment and postoperative rehabilitation are increasingly perfect, but the study of middle-aged total hip arthroplasty is less, especialy long curative effect in postoperative and long-term folow-up stil has many problems to be solved. In China, there are few studies addressing how to select the prosthesis during total hip arthroplasty in middle-aged patients, which kind or material of prosthesis is better, so the evidence for clinical application is less. OBJECTIVE:To compare and analyze the repair effects of bone cement total hip arthroplasty and uncemented total hip arthroplasty in middle-aged patients. METHODS:A total of 60 middle-aged patients who received total hip arthroplasty in the Department of Orthopedics, Xinjiang Uygur Autonomous Region Chinese Medicine Hospital from January 2005 to January 2008 were folowed up for 5 years. Their mean age was (37±6) years. There were 32 cases undergoing uncemented total hip arthroplasty and 28 cases receiving bone cement total hip arthroplasty. At 6 months, 2 and 5 years after replacement, Harris score for recovery of limb function and imaging findings were compared and analyzed. RESULTS AND CONCLUSION: Harris score for recovery of limb function was significantly better in the uncemented total hip arthroplasty group than in the bone cement total hip arthroplasty group at 6 months, 2 and 5 years after replacement (P < 0.01). No complications were found at 6 months in the uncemented total hip arthroplasty group, but one case affected osteolysis at 2 years and two cases experienced prosthesis loosing at 5 years after arthroplasty. In the bone cement total hip arthroplasty group, two cases had osteolysis and one case had prosthesis loosing at 6 months after arthroplasty, three cases had prosthesis loosing at 2 years, and two cases affected linear permeability dissolvement at 5 years after arthroplasty. These findings suggest that uncemented prosthesis achieved a high rate of functional restoration and a low rate of complications in middle-aged patients. Uncemented total hip arthroplasty had satisfactory clinical and radiographic outcomes at a minimum of 5-year folow-up.

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.

In order to improve the efficiency of drug screening on serotonin transporter (SERT) inhibitors, a high-throughput screening (HTS) model is established in RBL-2H3 cells. The RBL-2H3 cells are very similar to the serotonin genetic neuro, in modulation of post-receptor mechanisms and transduction pathway of SERT reactivated. Depending on a fluorescence substrate ASP+ used in detection method of inhibitor rates, it's convenient, quick, accurate and effective, not making the environmental biohazard compared with radioactive experiments. Furthermore, biological screening model combined with computer aided virtual screening technique describing high-throughput virtual screening (HTVS). Bayesian classification method and molecular fingerprint similarity were applied to virtual screening technique, for screening compounds in compound library. Some compounds have been found, and then validated further by biological screening model. Combination of HTS and HTVS improves the efficiency of screening SERT inhibitors.

BACKGROUND:Genetic factors, environment, chronic infection, and autoimmune disorders are considered to be involved in the pathogenesis of ankylosing spondylitis. Genetic factors play an important role in the pathogenesis of the disease. Ethnic and regional diversity of differentialy expressed genes has become research hotspot because of family aggregation and ethnic diversity of ankylosing spondylitis.
OBJECTIVE:To screen differentialy expressed genes in Xinjiang Uygur and Han patients with ankylosing spondylitis by microarray screening and compare differences in gene expressions.
METHODS: Uygur and Han patients with active ankylosing spondylitis in department of rheumatology of our hospital were randomly colected with five patients for each. In addition, three healthy volunteers were selected as controls. RNA from peripheral blood was extracted and used for microarray hybridization after probe preparation to screen differentialy expressed genes in ankylosing spondylitis samples and the microarray results were verified by semi-quantitative RT-PCR analysis.
RESULTS AND CONCLUSION: Twenty differentialy expressed miRNAs were screened in Uygur and Han patients with active ankylosing spondylitis (P < 0.05). From relationship analysis of target genes and miRNAs, 15 target genes corresponding to the 79 miRNAs involved in human leucocyte antigens and interleukins which linked to human immunity system were found. These findings suggest that differentialy expressed genes can be screened from Uygur and Han patients with ankylosing spondylitis.
