Objective To explore a new method for repairing multiple knee ligament injuries with allogenic achilles tendon. Methods Injuried anterior and posterior cruciate ligament(APCL) in 25 patients with multiple knee ligament injuries was reconstructed under arthroscopy with the bone- patellar tendon -bone which was treated with deep hypothermia and ? radiation. At the same time, injuried medial collateral ligament (MCL) or lateral tissue was repaired. Results After the disappearance of edema and inflammation in the injuried knee joints, the allogenic bone-patellar tendon-bone transplant was performed under arthroscopy. Menisci were sutured in 2 cases, and were resected or partially resected in 15 cases. All patients were followed up for more than 12 months. According to the Lysholm score method of knee function,the average score of preoperation and postoperation was 36 and 85, respectively. The satisfactory rate was 83%. The objective examination showed anterior drawer test(ADT) positive in 21 cases preoperatively, and 2 postoperatively. Lachman test was positive in 22 cases preoperatively, and 2 postoperatively. 3 patients had tolerable pain in knee, and 5 had the limitation of knee activity (5～20?). Conclusion The injury and complication caused by the autograft can be avoided by using allogenic bone- patellar tendon -bone to repair multiple knee ligament injuries. After systemic rehabilitation, the function of the knee joints can be restored reliably.

Objective:The aim of the present study was to examine the relationships between alexithymia, negative affect,and quality of life(QOL)of lung cancer patients receiving chemotherapy.Methods:51lung cancer patients receiving chemotherapy completed questionnaires of quality of life questionnaire for Chinese cancer patients receiving chemobiotherapy(QLQ-CCC),26-item Toronto alexithymia scale(TAS-26)and symptom checklist (SCL-90).Results:1)The patients had better score in QLQ(increased by 11%,P

Objective:To assess the clinical efficacy of two different diameter Osstem MS one-stage implant restoration of small edentu-lous space in the mandibular anterior region.Methods:85 patients were treated by Osstem MS one-stage implant with the diameter of 2.5 mm(n =66)and 3.0 mm(n =66)respectively for the restoration of small edentulous space in mandibular anterior region.The mesi-al and distal marginal bone level and soft tissue were statistically analyzed after 1 2 and 24 months of functional load.The implant survival rate was evaluated according to Wheeler's survival criteria.Results:The survival rate of the implants was 1 00%.The mean changes in marginal bone level(mm)on the mesial side of 2.5 mm and 3.0 mm diameter implants were 0.275 ±0.638 and 0.098 ±0.31 9,distal aspects were 0.360 ±0.588 and 0.1 09 ±0.323 after 1 2 months of functional load;while 0.299 ±0.672 and 0.099 ±0.31 8,0.381 ± 0.581 and 0.1 07 ±0.31 9 after 24 months of functional load.The mesial and distal marginal bone loss of 2.5 mm diameter implant was greater than that of 3.0 mm after 1 2 and 24 months of functional load(P <0.05).No significant change on the marginal bone level was found aomog the same diameter implants from 1 2 to 24 month observation(P >0.05).No relevant complication of peri-implant soft tissue was shown.Conclusion:Favorable clinical effects including function and aesthetics can be achieved by Osstem MS one-stage implant with the diameter of 2.5 mm or 3.0 mm for the restoration of small edentulous space in the mandibular anterior region,however,the mar-ginal bone loss was greater around 2.5 mm diameter implant.

Objective:To investigate the effects of 5-aza-2′deoxycytidine(5-aza-dC),a DNA methyltransferase (DNMT)inhibitor, on the methylation status of the RECK gene and the invasion of salivary adenoid cystic carcinoma cell lines.Methods:Methylation-specific PCR,Western blot analysis and quantitative real-time PCR were used to investigate the methylation status of RECK gene and the expression of RECK mRNA and protein in SACC cell lines.The invasive ability of SACC cells was examined by transwell assay. Results:Promoter methylation was only found in ACC-Mcell line and not in ACC-2 cell line.Treatment of ACC-Mcells with 5-aza-dC partially reversed the hypermethylation status of the RECK gene and significantly enhanced the expression level of mRNA and pro-tein of RECK,suppressed ACC-Mcell invasive ability.Conclusion:5-aza-dC can inhibit ACC-Mcell invasion by reversal of hyperm-ethylation status of RECK gene.

During the foreign aid mission against Ebola,the 302 Military Hospital of PLA strengthened emergency science research management according to the features of this task and the reality,and toke effective measures in research direction selection,human resources concordance,scientific potential transformation and other aspects,which contributed to the successful completion of this mission.They gathered experiences in emergency science research management and gave recommendations for similar tasks in the future.

Objective To evaluate the Laparoscopic combined fiber choledochoscope common bile duct cho-lelithotomy for my own clinical experience in rencent five years.Methods Clinic data of 25 cases with choledocholi-thiasis undergoing laparoscopic common bile duct cholelithotomy from June 2010 to March 2014 were retrospectively analyzed.Results The operation was performed successfully in 24 cases,a case conversions to laparotomy,21 cases with T-tube drainage,3 cases with primary ductal submucosa closure.The operative time was 105 to 305min,mean (184.0 ±12.2 ) min, postoperative hospitalization time was 6 to 10 day, mean ( 7.7 ±0.2 ) day, a case residual stones,no bile leakage.Conclusion The beginning of Laparoscopic combined fiber choledochoscope common bile duct cholelithotomy,one-stage suture of common bile duct should be selected carefully, timely transfer laparotomy, should not aim for laparoscopic surgery success rate.

Objective To study the application of extracellular laccase from endophytic fungi to total flavonoid extraction. Methods The extracellular laccase vitality of an endophytic Fusarium sp.C-8 from Artemisa annua reached 36.1 U/mL when the fungus was cultivated in revised PDA medium with initial pH 7.0 at 20℃ on a rotary shaker incubator for 6 d. The crude laccase from the cultural medium was applied for extraction of flavonoid from the buds of Sophara japonica. The optimization on the ratio of dry buds to crude enzyme liquid,temperature,time,and pH value was carried out during the process of laccase-assistant treatment. Results After incubation with 40∶1 of crude enzyme (pH 7.0) at 20℃ to dry buds for 1 h,the extraction rate of total flavonoids was 11.4 %,a more increase of 28.7 % than that in regular extraction process. Conclusion The results present a practical method of laccase-assistant extraction process on total flavones in S. japonica buds.
