Objective To investigate the role of rotational alignment reference landmarks of the proximal tibia in total knee arthroplasty.Methods Fifteen healthy adult volunteers were enrolled in this study,including 10 males and 5 females,aged from 21 to 38 years (average,28.1±6.0).CT scans of 26 knees were taken as the knees were placed in full extension.Two anteroposterior axes were drawn on the CT images:one line connected the middle of the posterior cruciate ligament insertion site and the medial edge of the patellar tendon,and another line connected the middle of the posterior cruciate ligament insertion site and the middle-medial 1/3 of the patellar tendon.The surgical epicondylar axis was also drawn on the CT images.Angles were measured between a line perpendicular to the surgical epicondylar axis and the two anteroposterior axes,and the angles were compared with the ideal tibial rotational alignment reference axis (0°).Results Angles between the line perpendicular to the surgical epicondylar axis and the line connecting the middle of the posterior cruciate ligament insertion site and the medial edge of the patellar tendon averaged 0.7°±2.8° (range,-5.1°-5.8°),there was no significant difference compared with 0°.Angles between the line perpendicular to the surgical epicondylar axis and the line connecting the middle of the posterior cruciate ligament insertion site and the middle-medial 1/3 of the patellar tendon averaged 6.9°±5.3° (range,-3.4°-14.1°),there was significant difference compared with 0°.Significant difference existed in angles between the two anteroposterior axes and the line perpendicular to the surgical epicondylar axis.Conclusion The line connecting the middle of the posterior cruciate ligament insertion site and the medial edge of the patellar tendon is a more reliable reference axis for the tibial component rotational alignment,which makes the femoral and tibial components in a more matching rotational position.

BACKGROUND:Recently,researches have found that insulin-like growth factor-1(IGF-1)can induce the differentiation of bone marrow-derived mesenchymal stem cells(BMSCs)into chondrocytes,but there are no reports concerning the differentiation of adipose-derived mesenchymal stem cells(ADMSCs)into chondrocytes induced by IGF-1,as well as interaction with transforming growth factor-β1(TGF-β1)during this process.OBJECTIVE:To explore the possibility of inducing ADMSCs chondrogenic differentiation by using IGF-1 and the interaction with TGF-β1 in induction.METHODS:ADMSCs were obtained,and seeded at 2×10~5 cells/cm~2 in culture flask.Insulin-free chondrogenic media containing IGF-1 or(and)TGF-β1 were used to induce ADMSCs.2 weeks later,cells were harvested and stained by using toluidine blue and collagen Ⅱ antibody immunohistochemistry.Intracellular sulfated proteoglycan and collagen Ⅱ coloring were observed.Reverse transcription-polymerase chain reaction(RT-PCR)was used to detect the expression of collagen Ⅱ,aggrecan and Sox9 mRNA.RESULTS AND CONCLUSION:After induced,toluidine blue stain exhibited that the cells in the three induction groups were polygonal,with cytoplasm and cell membrane of blue different dyeing.Immunohistochemistry for type Ⅱ collagen demonstrated that cytoplasm and cell membrane were stained brown in three induction groups.RT-PCR revealed that the expression of collagen Ⅱ,aggrecan,Sox9 mRNA of IGF + TGF group were significantly greater than the IGF and TGF groups,and IGF and TGF groups were significantly stronger than the control group.No significant difference was determined between the IGF and TGF groups.These results indicated that IGF-1 can induce chondrogenic differentiation from ADMSCs,expressing chondrocyte specific cell phenotype.There is synergism of IGF-1 and TGF-01 to induce the differentiation of ADMSCs into chondrocytes.

Objective To study the expression of epidermal growth factor receptor (EGFR) in cervical car-cinoma and cervical intraepithelial neoplasia(CIN),and to elucidate its relation with the genesis, infiltration, metas-tasis and prognosis of cervical carcinoma. Methods EGFR was determined by means of S-P immunohistochemistry in tissue of 100 cases of cervical carcinoma,60 cases of CIN and 40 cases of controls. Results The overexpression rates of EGFR were 0% (0/40), 51.67% (31/60),78.00% (78/100), respectively in normal cervical epithelium, CIN and cervical tumor tissues. The overexpression rate of EGFR was significantly higher in cervical tumor tissue than in control group(P<0.01). The overexpression of EGFR didn't demonstrate significant association with clinical staging, tumor size, pathological type, differentiation, cervical invasion depth, cervical canal invasion, lymphnode me-tastasis or the prognosis of cervical neoplasm (P>0.05). Conclusion Overexpression of EGFR is worsened with the severity of cervical lesion, suggesting that overexpression of EGFR is correlated with the genesis of cervical neo-plasms,which may be a valuable biological indicator of cervical carcinoma,but is not correlated with clinical patho-logical features and prognosis of cervical carcinoma.

Objective To explore the efficacy of process management on bladder function among traumatic brain injury (TBI) patients admitted to intensive rehabilitation and care unit (IRCU). Methods 33 cases were collected to control group who were cared with routing nursing during February, 2011 to December, 2012. Other 39 cases were recruited to trial group cared with process management of bladder function during January, 2013 to December, 2014. Process management of bladder function contained the establishment of process manage-ment guide, evaluation of removing catheter, nursing of bladder based on residue of urine volume and keeping a diary of urination, etc. Re-sults There were more cases with residue of urine volume less than 100 ml and less with catheter associated urinary tract infection in the tri-al group than in the control group (P<0.05). Conclusion Process management of bladder function can improve the recovery of bladder func-tion of TBI patients, shorten rehabilitation time and decrease the risk of catheter associated urinary tract infection.

Objective To identify predictors of prescription initiation and persistence of warfarin in non-valvular atrial fibrillation ( NVAF ) patients with high risk of stroke ( CHA2 DS2-VASc≥2 ) . Methods NVAF patients consulted in our hospital from Aug , 2011 to Apr, 2015 were enrolled.Patients who underwent radiofrequency catheter ablation were excluded . Patients were divided into two groups (warfarin group and non-warfarin group).Logistic regression was used to estimate the predictors of initiation warfarin prescription.Kaplan-Meier survival and Cox proportional hazards model was performed to determine rate of warfarin persistence and its associated factors .Results A total of 622 AF patients were enrolled and 490 patients with CHA2DS2-VASc≥2.Ten patients lost follow up and 480 patients were followed up with a mean follow-up period of ( 40.0 ±11.55 ) months.Of which 245 NVAF patients ( 51%) had a warfarin prescription.Patients with ischemic stroke ( OR 2.447 , 95%CI 1.435-4.171 , P=0.001 ) , heart failure ( OR 2.009 , 95%CI 1.084-3.724 , P=0.027 ) and persistent AF ( OR 2.231 , 95%CI 1.448-3.437 , P=0.0001 ) had a higher likelihood of warfarin prescription .Anemia ( OR 0.479 , 95%CI 0.238-0.964 , P=0.039), concommitant Traditional Chinese Medicine (TCM) use (OR 0.638, 95%CI 0.456-0.891, P=0.008 ) and longer distance to hospital ( OR 0.759 , 95%CI 0.610-0.945 , P=0.014 ) decreased the likelihood of warfarin prescription . One hundred and seventy-six ( 71.8%) warfarin users continued persistent therapy and the overall proportion of warfarin persistence was 78.3% for one year , 71.0% for 3 years.Seventy-six existing warfarin users continued the warfarin therapy (80%, 76/95),one hundred new users showed persistence to therapy ( 66.7%, 100/150 ) .Warfarin use before enrollment significantly increased warfarin persistence than new prescription ( P =0.008 ) .Variables associated with higher discontinuation were new prescription ( HR 1.786 , 95% CI 1.029-3.100 , P=0.039 ) , TCM use ( HR 1.687 , 95%CI 1.201-2.37 , P=0.003 ) and longer distance to hospital ( HR 1.446 , 95% CI 1.121-1.865, P=0.005).Conclusions In anticoagulation clinic, concommitant TCM use, distance to hospital and other factors were associated with warfarin initiation prescription and persistence .Identifying factors associated with warfarin treatment could help in developing adherence of patients .

Objective To evaluate the clinical effect of ambulatory labor analgesia used in latent phase of the first stage of labor, which include labor progress, Apgar score after ambulatory labor analgesia begun to use when the cervix was different size dilatated. Methods Seventy-five parturient primiparas who had no complication were randomly divided into three groups: group Ⅰ: ambulatory labor analgesia was begun to use when the cervix was 1.0 cm dilated, group Ⅱ: ambulatory labor analgesia was begun to use when the cervix was 2-3 cm dilated, group Ⅲ: control group without use of ambulatory labor analgesia. Analgesic effects were observed, changes of uterine contraction were recorded by fetal monitor. Meanwhile, total stage of labor ,outcome of delivery and Apgar score were recorded. Results Duration of total stage of labor had no significant difference between group Ⅰ and group Ⅲ.The duration of the first labor stage was significantly longer in group Ⅰ than that in group Ⅱ(P

Aim To investigate the protective effects of total triterpenoid from Prunella vulgaris L. ( TTP) on CCl4-induced hepatic fibrosis in rats and its mecha-nism. Methods Rat liver fibrosis was induced by 50% CCl4 twice a week for 12 weeks. From the 5th week, all the therapeutic groups were treated with the TTP(25, 50, 100 mg·kg-1 ) and the colchicine (0. 1 mg· kg-1 ) respectively once a day for 8 weeks. At the end of the twelfth week, the levels of ALT, AST, HA, PCⅢ, CⅣ, MDA, SOD, GSH-Px, Hyp were measured . HE and Masson staining were used to evalu-late the degree of hepatic fibrosis. The mRNA expres-sion ofα-SMA, procollagen I, Smad2, Smad3, Smad7 in liver was detected by RT-PCR, and the p-ERK pro-tein expression was evaluated by Western blot. Results Compared with the model group, TTP(25, 50, 100 mg·kg-1 ) not only reduced serum content of ALT, AST, HA, PCⅢ, CⅣand Hyp, MDA in liver tissue, improved the morphologic changes of hepatic fibrosis, but also increased SOD and GSH-Px activity. Moreo-ver, it decreased the α-SMA, procollagen I, Smad2, Smad3 mRNA expression and increased Smad7 mRNA expression in liver tissues obviously. Furthermore, TTP reduced the protein expression of p-ERK. Conclusions TTP can protect rats from CCl4-induced liver fibro-sis. The mechanism of this process may involve inhibi-ting the expression of p-ERK and interference with TGF-β1/Smad signal transduction pathway.

Objective To establish a cell line stably expressing the human CD36 by using TA clo-ning and cell transfection technology and to analyze its application to the detection of anti-CD36 antibodies. Methods Total RNA was isolated from human platelets and then used to synthesize complementary DNA ( cDNA) . Sequence of the gene encoding CD36 on human platelets was obtained by PCR amplification. The recombinant vector was transformed into TOP10 E. coli after TA cloning. The positive recombinant pcDNA3. 1/V5-CD36 plasmid was screened out by blue-white selection and then sequenced. The correctly constructed plasmid coated with Effectene? Transfection Reagent was transferred into HEK293T cells. Fluo-rescence-activated cell sorting was performed to screen out the cell line that could stably express the CD36 on human platelets. The transfected cell line-based flow cytometry analysis and antibody capture assay ( ACA) were established and used for antibody detection in nine serum samples positive for anti-CD36 antibodies. Results The HEK293T cell line stably expressing the recombinant CD36 was successfully established. Compare with the monoclonal antibody immobilization of platelet antigens assay ( MAIPA) , anti-CD36 anti-bodies could be easily identified in nine serum samples by using the transfected cell line-based flow cytome-try analysis and ACA. Conclusion This study suggests that the HEK293T cells stably expressing the re-combinant CD36 could be used in flow cytometry analysis and ACA for the detection of anti-CD36 antibod-ies. It also paves the way for further researches on the mechanism of CD36 in other diseases.
