Practical Oncology Journal 2014;(2):123-128
Objective The purpose of this study is to investigate CD 46 expression in advanced invasive breast cancer and in normal breast tissues , and to analyze the correlation between CD 4 expression and effect of neoadjuvant chemotherapy ,exploring its clinical significance for the prognostic value of neoadjuvant chemotherapy in breast cancer .Methods Immunohistochemistry was employed to detect CD 46 expression of tissue samples from 60 patients with invasive breast cancer and 30 normal breasts .We further analyzed the relationship between effect of neoadjuvant chemotherapy and CD 46 expression ,and the prognostic significance for the survival .Rseults CD46-positive rate in breast cancer was apparently higher than that in normal breast tissues (81.67% vs. 46.67%,P<0.05).After neoadjuvant chemotherapy,the CD46 expression was significantly decreased (P <0 .05).There was a negative correlation between CD 46 expression and efficacy of chemotherapy ( P<0.05). CD46 expression in breast cancer could be affected in cancer invasion ,lymph node metastasis(P<0.05).Con-clusion CD46 expression in breast cancer patients is higher than that in healthy people ,and was negatively cor-related with efficacy of adjuvant chemotherapy .The increasing rate of CD 46 positive expression has predictive val-ue for the poor prognosis of patients .

Journal of Regional Anatomy and Operative Surgery 2015;(2):190-192
Objective To compare the efficacy of two different surgery incisions on original corneal astigmatism in cataract surgery. Methods 300 patients (300 eyes) of cataract surgery from August 2012 to August 2013 in our hospital were included in the study,of which 150 patients in the observation group treated with transparent cornea incision in the steep axis of astigmatism,and the control group of 150 pa-tients received lateral ( right) or on the nose by the temporal side ( left) transparent cornea incision. Results In the third day,first month, third month,sixth month and 12th month after surgery,the average corneal astigmatism in the observation group was significantly lower than that before the surgery,which after a month the lowest ( +0. 79 ± 0. 92)D;average corneal astigmatism of patients in the control group were significantly higher than that before the surgery,corneal astigmatism after 3 days to reach the highest,( -5. 65 ± 0. 89)D,3 days after sur-gery,1 month, 3 months, 6 months and 12 months,patients in the observation group were significantly higher visual acuity patients,the differ-ence was statistically significant (P<0. 05). Conclusion Phacoemulsification clear corneal incision along the steep axis IOL implantation for cataract surgery can correct astigmatism original extent a certain extent,and to promote the recovery of visual acuity in patients with a grea-ter degree.

Journal of Acupuncture and Tuina Science 2007;5(1):59-60
Exterior-and interior-meridian acupoints were used, mainly by selection of local acupoints along meridian. According to the state of disease, electroacupuncture and acupoint injection were combined to treat brachial plexus injury. Among 12 patients, 6 cases were basically cured, 4 cases got effectiveness and 2 cases had no effectiveness. The therapeutic effect of exterior- and interior-meridian acupoints in brachial plexus injury was satisfactory.

5.Y-shape plate in the treatment of comminuted fractures of the distal humerus among 18 cases
Chinese Journal of Tissue Engineering Research 2007;0(35):-
AIM: To observe the adverse effect and clinical efficiency of Y-shape plate internal fixation for treating comminuted distal humeral fracture. METHODS: A retrospective analysis was conducted in 18 patients with the comminuted distal humeral fracture,who were admitted in the First Affiliated Hospital of Nanyang Medical College from January 2003 to December 2006. All patients were treated with Y-shape stainless steel or Ti-alloy plate in 3-7 holes,then the response of materials and host was observed. The curative efficiency was assayed with Cassebaum score,and the healing of fractures was detected with X-ray film. During follow-ups,the pain and joint motion were observed. RESULTS: The mean operational time was 134 minutes,the mean value of intraoperative blood loss was 172 mL,and all the incisions were healed well. All the patients were followed up for 6 months,and the mean time for the fracture healing was 14 weeks. One case appeared delayed healing in the resection lesion,and Kirschner's wire was loosened in 2 cases. There was no infection,local inflammatory reaction or rejection reaction occurred. Among 18 patients,11 got excellent results,4 good,2 fair,1 poor,and the rate of excellent and good efficiency was 83.3%. CONCLUSION: Y-shape plate after implantation shows good biocompatibility with the human body,with the manifestations of good reduction of comminuted distal humeral fracture,firm internal fixation,and satisfactory functional recovery of elbow joint.

Journal of Chongqing Medical University 1987;0(01):-
Objective:To investigate the mechanism of ursolic acid inducing the apoptosis of human nasopharyngeal carcinoma cell line CNE-2Z.Methods:CNE-2Z were treated by ursolic acid with different concentration.Cell proliferation was determined by MTT assay.Cell cycle and apoptosis rate were analysed by flow cytometry(FCM).The expressions of bax,bcl-2 and cox-2 were assessed by SP method of immunocytochemistry,while the expression of caspase 3 by Western blot.Results:Ursolic acid inhibited the proliferation of CNE-2Z cells and induced the apoptosis in dosage and time dependent manner.FCM showed that the cell population reduced in S phase and cell cycle was arrested in G0/G1 phase.Immunocytochemistry showed that the expression of bax was up-regulated in the apoptosis,while the expression of bcl-2 and cox-2 down-regulated.Western blot showed that the expression of caspase 3 was strengthened.Conclusion:Ursolic acid can induce apoptosis of CNE-2Z in vitro.Its molecular mechanism probably is through promoting activation of caspase3,up-regulating the expression of bax,and down-regulating the expressions of bcl-2 and cox-2.
