Kinematical alignment during total knee arthroplasty is an emerging process, and draws more and more attentions from scholars. Knee joint is close to normal joint after TKA through kinematical alighment, which has good clinical results and functional scores, and not increase failure probility. Thus, it may increase joint stress of patella-femur joint, lead to patellar maltracking and increase abrasion. The paper summarized defination and basical principle, operative method, clinical outcomes and deficiency of kinematical alignment during total knee arthroplasty, in order to choose a better way for kinematical alignment during total knee arthroplasty.

Objective To explore a simple and effective way of establishing a mice orthotopic tracheal transplantation model in studying bronchiolitis obliterans to reduce operation time. Methods Tracheas from C57BL/6 mice (n=30) were im?planted into Balb/c mice (n=30). Grafts and hosts were matched according to body weight.Orotracheal intubation and endo-stentwas used for trachea anastomose and animal model was establish. Operating time was also noted. Grafts were harvest?ed on Days 15, 30 and 60 after transplantation, using HE staining to observe pathological changes of allograft. Trachea block?ing rate was also calculated. Results Until survival of trachea transplantation, the operative time of donor′s and the recipi?ent′tracheas resection were (7.0±1.0) min and (7.0±1.0) min respectively.Orotracheal intubation the endo-stentestablish?ment cost(1 ± 0.5)min. Trachea anastomose took(20.0 ± 4.0)min and the operation time last(43.0 ± 10.0)min. Conclusion The improvement of orthotopic tracheas transplantation usingOrotracheal intubation the endo-stenfor trachea anastomose is esay-operated and did required complicate skills and instruments with high successful rate. So it is an ideal and stable model in studying bronchiolitis obliterans.

Leucine zipper tumor suppressor 2 (LZTS2) is a novel tumor suppressor gene that has been increasingly recognized in recent years. Currently, many studies illustrate that LZTS2 gene, the important candidate tumor suppressor gene, is already involved in the inhibition of tumorigenesis and aberrant proliferation of tumor cells, and other functions of tumor cells. Information from these stud-ies can contribute to the formulation of new strategies for the treatment of tumors.

The Coat protein and Maturase gene of E.coli bacteriophage MS2 was amplified by PCR,then the gene was cloned into pET32a to construct the intermediate vector pET32aCP.The conservative sequence of FMDV internal ribosome entry site(IRES) was cloned into the downstream of pET32aCP bacteriophage gene to construct the prokaryotic expression vector pCPES.The recombinant plasmid pCPES transformed into E.coli strain BL21(DE3) was induced to express with 1mmol/L IPTG.The expression products were purified by sucrose density gradient centrifugation.The expression products observed by TEM were circular viruslike particles,and the diameter of these particles was about 26nm.The stability of viruslike particles was detected,and the viruslike particles was identified by RTPCR.The results showed that the viruslike particles contain the FMDV IRES RNA and have good stability.The viruslike particles have great prospect as the standard and quality control in the area of RNA virus detection.

Objective To investigate the roles and significances of MMP-2 and MMP-9 in diffuse proliferative lupus nephritis by repeated renal biopsy.Methods Seventeen patients diagnosed by renal biopsy as WHO typeⅣlupus nephritis were analyzed by immunohistochemistry staining for MMP-2 and MMP-9. Double staining for MMP-2 and MT1-MMP,MMP-9 and CD68 were also performed.Patients had repeated renal biopsy after followed up for 2.5 years.The relationship between expressions of gelatinases and pathological activity index and clinical data were studied.Results MMP-2 immunoreactivity was detected in normal controls and was increased in diffuse proliferative lupus nephritis.MMP-9 staining,which was almost negative in normal giomeruli,was increased much more significantly in diffuse proliferative lupus nephritis. The immunoreactivity of MMP-2 and MMP-9 was positive in MT1-MMP staining and CD68-positive macrophages, respectively.The expression of MMP-2 and MMP-9 was reduced by 70% and 62% in 10 patients whose clinical condition was partially alleviated,while the expressions in 7 patients whose clinical condition was not alleviated,were only reduced by 27% and 32%.The staining for MMP-2 and MMP-9 were correlated with activity index of lupus nephritis and proteinuria.Conclusion Up-regulation of gelatinases expression in diffuse proliferate lupus nephritis is correlated to activity index of the disease.

Objective To analyze the clinical efficacy of capecitabine monotherapy or in combination with oxaliplatin concurrent chemoradio-therapy on patients with advanced colorectal cancer.Methods Fifty-two patients with advanced colorectal cancer were randomly divided into treatment group and control group , 26 cases in each group.Two groups were all taken 6 mV X -ray irradiation, 5 times a week, totally five weeks.On the same time , control group was given capecitabine , twice a day, with the total dose of 1500-1700 mg· m-2 .Treatment group was given oxaliplatin total dose of 50 -75 mg · m -2 , once a week , and capecitabine, twice a day, with the total dose of 1200-1550 mg· m-2.And 35 d a course , all patients were given three courses treatment.Clini-cal efficacy , improvement in quality of life and adverse drug reactions of the two groups were observed.Results After treatment, the objective response rate in treatment group (76.93%) was significantly higher than that in control group ( 42.31%, P<0.05 ); the quality of life in treat-ment group was significantly better than that in control group ( P<0.05 ).The incidence rate adverse reactions in treatment group were significantly lower than that in control group ( P<0.05 ).Conclusion Capecitabine combined with oxaliplatin for the treatment of patients with advanced colorectal cancer had a good clinical efficacy , low incidence of adversereactions , which can improve the quality of life.

The effects of Cinnamon granules on pharmacokinetics of berberine in Rhizoma Coptidis granules in healthy male volunteers, and the compatibility mechanism of Jiao-Tai-Wan (JTW) composed of Rhizoma Coptidis granules and Cinnamon granules were investigated. The concentration of berberine in plasma of healthy male volunteers was determined directly by high performance liquid chromatography (HPLC) after an oral administration of Rhizoma Coptidis granules alone or combined with Cinnamon granules (JTW). The plasma concentration-time curves of berberine were plotted. The data were analyzed with Drug and Statistics (DAS) 2.0 pharmacokinetic program (Chinese Pharmacology Society) to obtain the main pharmacokinetic parameters. The results showed that the plasma concentration-time curve of berberine was described by a two-compartment model. The C(max), T(max), t(1/2) and CLz/F of berberine in Rhizoma Coptidis granules were 360.883 μg/L, 2.0 h, 3.882 h, 119.320 L·h(-1)·kg(-1) respectively, and those of berberine in JTW were 396.124 μg/L, 1.5 h, 4.727 h, 57.709 L·h(-1)·kg(-1) respectively. It was suggested that Rhizoma Coptidis granules combined with Cinnamon granules could increase the plasma concentration of berberine, promote berberine absorption and lengthen the detention time of berberine in healthy male volunteers.
