Objective To discuss the effect of operations for comminuted patella fractures with cable cerclage and revised tension band. Method Retrospective study of clinical effects of 120 patella fractures cases which used cable(cable group,55 cases) or NT-PC (NT-PC group,65 cases) to internal fix.Results At 10 to 38 ( 19.50 ± 1.15 ) months follow-up, all cured well in 12 weeks. Compared with the operative time, the amount of blood loss, length of hospitalization, time for cure, the incidence of complications,there were no significant differences between two groups (P ＞ 0.05 ). The B (o)stman score of cable group [(27.0 ±0.2) scores] was better than that of NT-PC group [(25.1 ±0.6) scores](P＜0.05). Conclusion Using cable cerclage and revised tension band to internal fix for comminuted patella fractures,the operations are facile and the results are satisfactory.

To observe and evaluate the effects of manipulation on knee osteoarthritis (KOA) using T2-mapping and magnetic resonance imaging (MRI)-based volume measurements.

Objective: To study the alteration of hydrogen sulfide (H_2S)/ cystathionine-?-synthase (CBS) system during recurrent febrile seizures (FS) in the hippocampus of developing rats. Methods: The rats were randomly divided into control group (n=8) and hyperthermia-treated group (n=22). Which was subdivided into FS group (n=8) and H group(no seizure occurred, n=9) according to whether seizures occurred. The plasma level of H_2S was detected by the spectrophotometer. The expression levels of CBS gene and protein were examined by in situ hybridization and immunohistochemistry respectively. Results: The plasma levels of H_2S were increased significantly in FS group compared with those of control group or H group. The expression levels of CBS gene and protein were enhanced in FS group compared with those of control group or H group. Conclusion: The expression levels of H_2S/ CBS system were up-regulated during recurrent FS.

Osteoarthritis (OA) is a chronic joint disease that involves degeneration of articular cartilage, limited intra-articular inflammation manifested by synovitis and changes in the subchondral bone. After the articular cartilage's stability and complex structure in the framework of pressure-proof were destruct, the ability to repair by itself was weak. Therefore early diagnosis in the treatment of osteoarthritis is a focal ponit. This paper addressed on the characteristics of diagnosis of OA in the relevant objective diagnostic methods.

ObjectiveTo find out the inhibitory effects of CD4 - CD8 - DNT cells on growth of which depresses the pancreatic cancer in vitro and in vivo.Methods The inhibitory effects of DNT cells on the growth of Panc- 1 were studied in vitro by MTT method.Eighteen BALB/c mice were divided into 3 groups randomly.Human pancreatic cancer xenografts were established in 2 groups randomly.The last group was injected the cell suspension which comprises DNT and Panc- 1 cells ( Panc- 1∶ DNT =1∶ 5 ).When the diameter of tumor was about 5 mm,the first 2 group mice were further divided into 2 groups randomly.One was control,treated with distilled water.The other was treated with celebrex (4 mg/d).The size of the tumors was calculated every 2 weeks and tumor growth curve was depicted.At the end of the treatments,the mice were sacrific and the tumors were harvested.The tumor inhibition rate was calculated.Results( 1 ) MTT study showed that DNT cells produced a dose- dependent inhibition of Panc- 1 proliferation in vitro.(2) The growth of transplanted pancreatic cancer was down-regulated by treatment of DNT cells.ConclusionDNT cells can inhibit the growth of pancreatic cancer in vitro and in vivo.

To evaluate the efficacy of manipulation therapy in repairing thin-layer and thick-layer articular cartilage defects in rabbits.

Objective To discuss the relationship of congenital choledochus cyst(CCC)with occurrence of pancreatitis in adults and methods of surgical treatment.Methods The clinical data of 17 adult patients with congenital choledochus cyst who underwent surgical treatment from 1997-2005 were analyzed retrospectively.Results Clinical diagnosis was made mainly by B-ultrasound,MRCP,intraoperative cholangiography,ERCP and CT scans.Among 17 cases,10 cases were congenital choledochus cyst typeⅠ,4 cases type Ⅱ,1 case type Ⅲ,1 case type Ⅳ and 1 case type Ⅴ;and associated with cholelithiasis in 14 cases(bile pigment stone in 11cases,cholesterol calculus 3cases),chronic cholecytitis 5 cases,polypoid lesions of gallbladder 1 case,anomalous pancreaticobiliary junction(APBJ)10 cases,and pancreatitis 10 cases.Resection of extrahepatic cyst with Roux-y hepaticojejunostimy was performed in 15 cases,preserving pylorus pancreatoduodinectomy in 1 case,and cholecystectomy and T tube drainage in 1 case.Excellent and good results were achieved on follow-up in 14 out of the 17 CCC cases undergoing surgical treatment,while pancreatitis occurred in 2 cases and unexpected death in 1 case.Conclusions Pancreatitis is apt to occurr in CCC with APBJ and bile pigment stone in choledochus.The incidence of pancreatitis in CCC and APBJ(P-B)can be decreased by resection of extrahepatic cyst and Roux-en-Y hepaticojejunostimy and cholecystectomy.

Objective The immune magnetic separation(MACS)method of DNT cells was set up and their content Was detected in peripheral blood of healthy man.Methods DNT cells were separated from the peripheral blood.Trypan blue staining and flow cytometry were used to detect their activity and purity,and flow cytometry Was used to detect their content in normal human peripheral blood.Results DNT cell activi ty using MACS sorting was＞97%,the purity Was 82.77%;DNT cells accounted for(6.25±2.61)% (n=45)in the TCRαβ+T cells.Conclusion MACS Can quickly sort out high purity DNT cells,and do not affect the vitality of cells.DNT cells accounted for(6.25±2.61)%in the TCRCD3+T cells.

Objective To understand the pathogenesis of primary hypothyroidism associated with polymyositis-like syndrome.Method Four cases were presented and the clinical characteristics were analyzed.Results All of the four patients were male.Complaints of weakness primarily affecting proximal muscles and elevation of muscle enzymes were presented.Primary hypothyroidism was diagnosed after clinical examination.Complaints of weakness and the elevated muscle enzymes were all improved after the substitution of thyroxine.Conclusion Hypothyroidism could cause polymyositis-like syndrome,and thyroid function should be screened when elevation of muscle enzymes is presented.

In April 10, 2010, an earthquake measuring magnitude 7.1 shocked Yushu County,Qinghai province. For medical rescue, the National Earthquake Disaster Emergency Rescue Team was sent to Yushu right away. Rescue work in Yushu was faced with such difficulties as short preparative time, heavy workload, high exposure to various acute high altitude diseases (AHAD), and a number of other diseases frequently found on the cold plateau. To ensure the rescue work a success, the team took a series of measures including efficient preparative procedure, scientific and logical procedure in the emergency medical aid operations, reliable and effective handling of AHADs, along with sufficient self protection for team members.
