Objective To analyze the effect of GC-rich DNA fragments on the level of transgenic expression in Chinese hamster ovary (CHO) celts and its position effect.Methods The synthetic DNA fragment with GC-rich was cloned into the 5'or 3'or both 5'and 3'ends of expression cassette of expression vector.Three new expression vectors (pIRES-G1,pIRES-G2 and pIRES-G3) which was inserted with the GC-rich DNA fragments in different position were transfected CHO ceils,respectively,and then was observed under fluorescence microscope;the control vector was pIRES-EGFP.Stable transfected cell lines were screened under G418,and enhanced green fluorescent protein(EGFP) expression was analyzed by flow cytometry and the transgenic copy number was detected by quantitative real-time quantitative polymerase chain reaction (qRT-PCR).Results Three expression vectors with a GC-rich DNA fragments in different position were constructed successfully.The insertion of GC-rich DNA fragments at 3'end and both 5',3'ends of the box of expression vector could obviously improve the expression level of vector in CHO cells;and the expression level of the stably transfected CHO cells increased 1.39 fold and 1.32 fold compared to the control vector,respectively;the transgene copy number increased 1.32 fold and 1.24 fold compared with the control vector.While the insertion of GC-rich DNA fragments at 5'end of expression cassette had no obvious effect on the level of gene expression.Conclusion The role of DNA fragment with GC-rich in improving the transgenic expression of CHO cells is related to its position in the vector.The insertion of GC-rich DNA fragments at 3'end and both 5',3'ends of the box of expression vector can improve transgenic expression.

Objective To observe the clinical efficacy of Wenshen Xiaochuan Paste Recipe (WXPR) in preventing bronchial asthma, and to explore the mechanism. Methods Eighty patients were randomly divided into treatment group and control group. Each group had 40 patients. The control group was treated by conventional western medicine such as inhalation of steroid, and the treatment group was given oral use of WXPR based on the treatment for the control group. Treatment for both groups covered 60 days, and the follow-up lasted 10 months. The clinical outcomes included the clinical efficacy and immune indexes of peripheral blood T lymphocyte subsets CD3+, CD4+, CD8+and CD4+/CD8+ratio, and the serum IgE level. Results (1) After treatment and 12 months later, the scores of asthma control test (ACT ) in the two groups were increased obviously as compared with those before treatment, and there were statistically significant differences (P<0.05 or P<0.01) . The differences of ACT scores between the two groups were insignificant after treatment ( P>0.05) , but were significant ( P<0.05) 12 months later. (2) Within one year after treatment, the frequency of acute asthma attack was decreased in both groups (P<0.05 compared with that before treatment), and the treatment group had better effect on decreasing the attack frequency than the control group (P<0.05). (3) After treatment, the serum IgE, CD4+level, and CD4+/CD8+ ratio were decreased significantly, while CD8+ level was increased in the treatment group, and there were statistically significant differences ( P<0.05 compared with those before treatment). However, the differences of immune indexes in the control group were insignificant before and after treatment ( P>0.05). The improvement of immune indexes in the treatment group was superior to that in the control group ( P<0.05). Conclusion WXPR has good clinical efficacy in preventing and treating bronchial asthma. The mechanism is related with the inhibition of airway inflammation and improvement of immune function probably through regulating T lymphocyte subsets and lowering serum IgE level in asthma patients.

BACKGROUND:With the development of surgical techniques and reconstruction material technology, joint replacement has also been widely used in the dislocation of the shoulder;especial y al kinds of custom-made or assembled prosthesis make replacement indications improved evidently. OBJECTIVE:To investigate the long-term effects of arthroscopy or arthroplasty for treating recurrent anterior dislocation of the shoulder joint with severe bone defects. METHODS:144 patients with recurrent anterior dislocation of the shoulder joint with severe bone defects were enrol ed in this study. They were divided into treatment group and control group based on a random drawing (n=72). The control group was given arthroscopic surgery, and the treatment group was subjected to arthroplasty. The 3 years of fol owed-up were done by telephone investigation and further consultation. Neer shoulder score, shoulder activity and complications were recorded.
RESULTS AND CONCLUSION:After 3-year fol owed-up, the excel ent and good rate of shoulder function was significantly higher in the treatment group (90%) than in the control group (81%) (P<0.05). The magnitude of the flexion in the 3-year fol owed-up was apparently increased, while the lateral margin external rotation was decreased, which showed significant differences after intragroup comparison (P<0.05). Simultaneously, the magnitude of the flexion and the lateral margin external rotation in the treatment group had statistical y significant differences compared to the control group in the 3-year fol owed-up (P<0.05). The complications of wound infection, shoulder dislocation, and implant loosening in the treatment group during fol ow-up were significantly lower than in the control group (P<0.05). These findings verified that compared with arthroscopic surgery, arthroplasty for treating recurrent anterior dislocation of the shoulder joint with severe bone defects in long-term fol ow-up can effectively restore shoulder function and range of motion, and it has few complications, thereby effectively rebuilds shoulder joint.

BACKGROUND:Traditionaly, non-surgical treatment was used to treat degenerative femoral intercondylar fossa impingement syndrome, but it can cause function loss of cruciate ligament, or knee instability. With the development of medical technology, more and more views believed that ligament damage and combined with other knee structural damage should receive surgery as soon as possible.
OBJECTIVE: To investigate the repair effect of knee arthroplasty for treating degenerative femoral intercondylar fossa impingement syndrome, and compare with AO cannulated screw fixation.
METHODS:A total of 72 patients with degenerative femoral intercondylar fossa impingement syndrome were equaly and randomly divided into treatment group and control group. Patients in the control group were treated with open AO cannulated screw fixation, and patients in the treatment group were subjected to knee arthroplasty. At 7 days after treatment, repair effect was evaluated. Before treatment and 7 days after treatment, knee function was assessed by using Lysholm knee Scoring Scale and the international knee documentation committee knee evaluation form. Al patients were folowed up for 6 months after treatment to investigate the occurrence of complications.
RESULTS AND CONCLUSION:The surgery was successfuly completed in al patients. At 7 days after treatment, the excelent and good rate was 94% in the treatment group and 75% in the control group. The excelent and good rate was significantly higher in the treatment group than in the control group (P < 0.05). Lysholm scores were significantly greater, but the international knee documentation committee knee evaluation form scores were significantly lower at 7 days after treatment compared with that before treatment in the treatment group (P < 0.05). Simultaneously, Lysholm scores and the international knee documentation committee knee evaluation form scores were significantly better in the treatment group than in the control group at 7 days after treatment (P < 0.05). During 6-month folow-up, wound infection, intra-articular infection, joint pain, and deep vein thrombosis were significantly less in the treatment group than in the control group (P < 0.05). These findings indicate that knee arthroplasty for degenerative femoral intercondylar fossa impingement syndrome can improve short-term efficacy, effectively restore knee function and reduce the incidence of postoperative complications.

BACKGROUND:Arthroscopy can observe the involutive relation of patelofemoral joint directly and dynamicaly, which can be used to judge whether the patelofemoral joint abnormalities can be completely corrected. OBJECTIVE:To analyze the clinical effect of lateral retinacular release and ligament reconstruction under arthroscope for patela recurrent dislocation. METHODS: A total of 58 patients diagnosed as having recurrent patelar dislocations were divided randomly into control and experimental groups, with 29 cases in each group. Patients in the control group received lateral retinacular release and ligament reconstruction under common operation and those in the experimental group received lateral retinacular release and ligament reconstruction under arthroscopy. RESULTS AND CONCLUSION:There was no significant difference in the Lysholm and Kujala scores before treatment in the two groups (P > 0.05), but at 12 months after treatment, the Lysholm and Kujala scores were both increased in the two groups, especialy in the treatment group (P < 0.05). No difference was found in the congruence angle and lateral patelofemoral angle with CT value at 30° of knee flexion (P > 0.05), and CT measurement values of the congruence angle and lateral patelofemoral angle were both decreased in the two groups, especialy in the experimental group, at 12 months after treatment. In addition, the operation time, healing time, and total effective rate were better in the experimental group than the control group (P < 0.05). These results indicate that the lateral retinacular release and ligament reconstruction under arthroscopy has a better effect on recurrent patelar dislocation.

Objective To investigate the value of human epididymis secretory protein 4 ( HE4 ) combined with CA125 assay in differential diagnosis of endometriosis cyst and ovarian malignant tumor.Methods The level of HE4 and CA125 were measured by enzyme-linked immunosorbent assay (ELISA) in the serum specimens of 46 cases in endometriosis cyst group,36 cases in malignant ovarian tumor group,60 cases in benign ovarian diseases and 50 women in healthy women group.Those results were shown with median level.The normal range were 0-150 pmol/L in HE4 and 0-35 kU/L,which either one was more than the threshold value defined as positive index.The sensitivity of assay was evaluated by receiver operating characteristic (ROC) curve,the relation and value of HE4 or CA125 alone and combination assay in diagnosis of endometriosis was analyzed by Mann-Whitney U test and correlation analysis.Results (1) HE4:the median levels of HE4 were 52.4,51.0,50.0 pmol/L in group of endometriosis,normal control and benign ovarian tumor,which didn't show statistical difference.However,HE4 was 507.5 pmol/L inovarian cancer group,which was significantly higher than those of 3 groups (P < 0.05 ).(2 ) CA125:there were significant different in median level of CA125 was observed as 743.0 kU/L in ovarian cancer,84.9 kU/L in endoemtriosis,15.4 kU/L in benign ovarian disease,and 11.5 kU/L in healthy women (P < 0.05).( 3 ) The single assay:when compared with that in endometriosis group,receiver operating characteristic area under the curve( ROC-AUC) were 0.933 in HE4 alone and 0.821 in CA125 alone assay in ovarian cancer group.The specificity was 95% and the sensitivity was 79.6% and 49.0%.(4) The combination assay:when compared with those in endometriosis group,the ROC-AUC was 0.936,the specificity was 95% and the sensitivity was 81.0% in ovarian cancer.Conclusions Measurement of HE4 could be used in differential diagnosis of endometriosis cyst.And the combination of HE4 and CA125 assay could discriminate ovarian endometriosis cysts from ovarian malignant tumors effectively.

Objective To evaluate the anti-HBV effect of hypericin from the cellular level and to preliminarily explore its po-tential drug target point.Methods Liver cell line HepG2.2.15 cells secreting HBV particles were selected as the experimental ob-jects.Hypericin served as the HY group,lamivudine was taken as 3TC group and deionized water as the blank control group.The cells were grouped and administrated.The HBV-DNA copy level was measured at72 h after medication by Southern blot and fluo-rescent quantitative PCR;the inhibition rate of HBsAg and HBeAg was detected by using ELISA assay;the pgRNA expression level was tested by using Northern blot and fluorescent quantitative PCR;Western blot and fluorescent quantitative PCR were adopted to detect the expression of regulatory factors including HNF3β,HNF4α,PPARαand RXRα.Results Compared to the blank control group,both hypericin and lamivudine had significant inhibiting effect on HBV DNA and expression level of HBsAg and HBeAg in HepG2.2.15 cells (P <0.05).Hypericin could significantly decrease the pgRNA expression compared with the blank control group (P <0.05),while lamivudine had no obvious change (P <0.05).Moreover,hypericin exhibited significant effects on the expression of HNF3βand regulatory factor HNF4αcompared with the blank control group and 3TC group(P <0.05).Conclusion Hypericin represents a strong anti-HBV effect,moreover could increase the negative regulatory factor HNF3βn expression and decreases the positive factor HNF4αexpression,prompting that its drug target point could be pgRNA.

Objective:To investigate the expressions and correlation of bcl-2, programmed death-1 (PD-1) and programmed death ligand-1(PD-L1) in diffuse large B-cell lymphoma (DLBCL) tissue specimens, and the relationship between chemotherapy efficacy and prognosis of DLBCL patients.Methods:The expressions of bcl-2, PD-1 and PD-L1 in 82 patients with DLBCL who were admitted to Chenzhou First People's Hospital of Hunan Province from May 2011 to April 2014 were detected by using immunohistochemistry, and the correlation of the expressions of bcl-2, PD-1 and PD-L1 with clinicopathological characteristics and prognosis was analyzed.Results:The positive rate of bcl-2, PD-L1 and PD-1 in cancer tissues of DLBCL patients was 53.7% (44/82), 56.1% (46/82) and 32.9% (27/82), respectively. There was a correlation between bcl-2 and PD-L1 expression ( r = 0.306, P = 0.005). Bcl-2 was highly expressed in patients with international prognosis index (IPI) score 3-4 points, non-germinal center B-cell-like (non-GCB) subtype and B symptoms (all P < 0.05); PD-1 was highly expressed in patients with IPI score 3-4 points ( P < 0.05); PD-L1 was highly expressed in patients with IPI score 3-4 points, tumor stage Ⅲ-Ⅳ, B symptoms, ≥60 years old, and non-GCB (all P < 0.05). The overall survival (OS) and progression-free survival (PFS) in bcl-2-negative group were better than those in the bcl-2-positive group, and the differences were statistically significant (both P < 0.05); OS and PFS in PD-L1-negative group were better than those in PD-L1-positive group, and the differences were statistically significant(both P < 0.01). There were no statistical differences in OS and PFS between PD-1-positive group and PD-1-negative group (both P > 0.05). OS and PFS in bcl-2 and PD-L1 co-expression group were worse than those in both negative or any negative group (all P < 0.01), and PFS in bcl-2 and PD-1 co-expression group was worse than those in both negative or any negative group ( P = 0.044). Cox multivariate analysis showed IPI score 3-4 points and B symptoms were the independent influencing factors of OS in DLBCL patients (both P < 0.01); IPI score 3-4 points, B symptoms and PD-L1-positive were the independent influencing factors of poor PFS in DLBCL patients (all P < 0.05). Conclusion:The positive expressions of bcl-2 and PD-L1 are the independent factors for the poor prognosis of DLBCL patients, which may become new targets for the treatment of DLBCL.
