ObjectiveTo compare the therapeutic efficacy of acupuncture plus medication versus using Chinese medication or acupuncture alone in treating perimenopausal syndrome.MethodNinety patients with perimenopausal syndrome were randomized into 3 groups, 30 in each group, to respectively receive acupuncture plus Chinese medication, Chinese medication alone, and acupuncture alone, totally for 3 months. Modified Kupperman index was adopted to evaluate therapeutic efficacy.ResultAfter intervention, the Kupperman scores decreased significantly in all three groups (P<0.01). The Kupperman score of the acupuncture-medication group was markedly superior to that ofthe medication group and acupuncture group (P<0.05).Conclusion Combination of acupuncture and medication can significantly improve the symptoms of perimenopausal syndrome, and is valuablein clinic.

ObjectiveTo investigate the efficacy of along-meridian distal point selection in treating post-cerebral infarction shoulder-hand syndrome.MethodSixty patients with post-cerebral infarction shoulder-hand syndrome were randomly allocated to treatment and control groups, 30 cases each. The control group was treated by routine neurological medical treatment, conventional acupuncture for stroke-attack on meridians and rehabilitation training and the treatment group, by along-meridian distal point selection in addition. The therapeutic effects were evaluated in both groups after four courses of treatment. The VAS scores, affected-side hand swelling scores and upper limb FMA scores were compared between the two groups before and after treatment. ResultThe VAS score, affected-side hand swelling score and upper limb FMA score were significantly better in both groups after treatment than before (P<0.01). Post-treatment VAS score, affected-side hand swelling score and upper limb FMA score were significantly better in the treatment group than in the control group; there were statistically significant differences (P<0.01,P<0.05). ConclusionAlong-meridian distal point selection has clinically a better improving effect on the pain, affected-side hand swelling and upper limb function in patients with post-cerebral infarction shoulder-hand syndrome.

Objective:To establish an experimental phalloplasty model with sensory restoration in rabbits and to explore a new surgical technique to improve the postoperative sensory function in phallic reconstruction. Methods: Adult male New Zealand white rabbit was used. Penile reconstruction was performed with superficial epigastric faciovascular pedicle flap. Free saphenous nerve graft was dissected, embedded in the flap, and end-to-end anastomosed to dorsal nerve of penis. Postoperatively, H-E staining and CGRP immunohistochemical staining were applied to observe the morphology of the regenerated nerves in the reconstructed penis at different stages. Results:Only a few CGRP-positive fibers scattered in deep corium in the reconstructed penis 1 month after surgery, while the quantity of CGRP nerve fibers increased markedly and the CGRP-positive fibers appeared in both superficial corium and papillae corii after 3 months. Six months postoperatively, the positive nerve fibers were also observed around the cutaneous accessories and in the epidermis-corium boundary layer. Conclusion: This rabbit model demonstrates the possibility of a new method for phalloplasty with sensory recovery, which may redound to clinical application.

ObjectiveTo study the inhibiting effects on the invasion and metastasis of melanoma by CXCR4 gene silence in nude mice.MethodsThe CXCR4 specific recombinant plasmid vector was constructed and transfected into the cultured MV3 cell line with lipofectamine.The models of subcutaneous melanoma in nude mice were established with MV3 cells.The nude mouse model of lung metastasis was established by injection of MV3 cells into the tail vein.The animals were sacrificed at 8weeks after the melanoma cells injection.CXCR4-shRNA plasmid vectors were discontinuously injected directly into the established tumor and vein.The changes of weight and size of the tumors and the mice body weight during the therapy were calculated respectively.Histological observation was performed to evaluate the presence and number of metastatic tumors.ResultsThe subcutaneous melanoma tumors in nude mice were established successfully.The growth of tumors in the CXCR4-shRNA injected nude mice was inhibitted obviously through tumor growth curve. There were significant differences between negative shRNA control nude mice and blank control nude mice (P＜0.01).Melanoma cells with CXCR4 shRNA permanent transfection had a much lower lung and brain and liver metastatic potential in nude mice than control cells and mock control cells in vivo.ConclusionsCXCR4 gene silencing mediated by shRNA significantly suppresses the growth of MV3 cell in vitro.Silencing of CXCR4 mediated by shRNA can also effectively decrease the metastatic potential of lung and liver and brain.

Objective To confirm whether in post-resuscitation myocardial dysfunction involved in myocyte apoptosis mechanism in porcine model of cardiac arrest and apoptosis index varied from different modalities of cardiopulmonary resuscitation or not.Methods A total of 22 WZSP inbred small swine were randomly (random number) divided into sham operation group (SHAM) (n =6),defibrillation first group (DF,n =8) and chest compression first group (CF,n =8).Eight minutes after ventricular fibrillation was set up,standard CPR was carried out subsequently after defibrillation in porcine models of cardiac arrest in DF group and defibrillation after standard CPR in CF group,and hemodynamics were monitored.Twentyfour hours after restoration of spontaneous circulation (ROSC),animals were sacrificed,and myocardial specimens were examined with electron microscopy,Western blot,quantitative RT-PCR,and terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL) assay.The experimental data were analyzed by SPSS 17.0.Student's t test was employed for comparisons between two groups.Differences within groups at different time intervals were compared with repeated measures ANOVA.A two-tailed value of P ＜ 0.05 was considered statistically significant.Results Myocardial function was significantly impaired after ROSC.Levels of Bcl-2,Bax and caspase-3 protein was markedly increased in the CF and DF groups than those in the SHAM group (P ＜ 0.05) at 24 h after ROSC,while Bcl-2/Bax was significantly reduced in the CF and DF group compared with the SHAM group (P ＜ 0.05),and much more apoptotic cells were observed in cardiac arrest animals in comparison with sham-operation animals (P ＜ 0.05).Six hours after ROSC,hemodynamic indicators improved significantly in group DF than those in group CF,but Bcl-2,Bax and caspase-3 protein levels and apoptotic index were not significantly different bewteen the DF group and CF group (P ＞ 0.05).Conclusions Caspase-3-mediated apoptosis might be one of the main pathological mechanisms of postresuscitation myocardial injury in a porcine model of cardiac arrest,but there was no statistically significant difference in apoptosis index between two resuscitation modalities,showing no one modality was superior over another.

AIM:To observe the effect on NF-?B pathway and cell motility in breast cancer cell lines after transfection of dominant negative I?B? plasmid.METHODS:After stable transfection of mutant I?B? plasmid into highly metastatic breast cancer lines MDA-MB-231 and MDA-MB-435,we detected NF-?B binding activity by EMSA,cell growth ability by cell growth curve,colony forming test,and cell motility by millicell-PCF chamber.RESULTS:Constitutive activities in MDA-MB-231 and MDA-MB-435 were observed.Stable transfection of a dominant negative Ⅰ?B? resulted in downregulation of NF-?B binding activity,thus inhibited cell mobility without significant effect on cell growth.CONCLUSION:Cell migration ability is inhibited in highly invasive breast cancer cells by inhibition of NF-?B pathway in vitro.

Objective To investigate the clinical effect of induction chemotherapy plus concurrent radiochemotherapy in the treatment of locally advanced non-small cell lung cancer (NSCLC) through a meta-analysis.Methods CBM, CNKI, Cochrane Library, PubMed, and EMbase were searched for the articles on comparison between induction chemotherapy plus concurrent radiochemotherapy and concurrent radiochemotherapy for patients with locally advanced NSCLC.According to the inclusion and exclusion criteria, the data on short-term outcome and survival were collected.A Meta-analysis was performed to evaluate the clinical effect of induction chemotherapy followed by concurrent radiochemotherapy.Results A total of 5 articles were included, which involved 845 patients.The results showed that the short-term outcome and the 2-and 3-year survival rates were similar between patients receiving induction chemotherapy plus concurrent radiochemotherapy and those receiving concurrent radiochemotherapy ( OR=0.875, 95% CI 0.507-1.510, P=0.631;HR=0.770, 95% CI 0.515-1.151, P=0.203;HR=0.809, 95% CI 0.559-1.172, P=0.262), but the patients receiving induction chemotherapy plus concurrent radiochemotherapy showed a significantly higher incidence rate of grade ≥ 3 leukopenia than those receiving concurrent radiochemotherapy alone ( OR=0.637, 95% CI 0.435-0.931, P=0.020).Conclusions Induction chemotherapy plus concurrent radiochemotherapy shows no significant advantages over concurrent radiochemotherapy alone in the short-term outcome and 2-and 3-year survival rates, but it significantly increases myelosuppression.Since there are few studies involving a limited number of cases included in this analysis, more multicenter randomized trials are needed to provide more detailed data and further clarify the clinical value of induction chemotherapy plus concurrent radiochemotherapy.

AIM: To investigate the role of nuclear factor ?B (NF-?B) in the induction of IL-8 gene by TNF-? in colon cancer cells and the effect of antioxidant on the induction of IL-8. METHODS: ELISA was used to detect the concentrations of IL-8. IL-8 mRNA was analyzed by using RT-PCR. NF-?B in the cell nuclei was detected with electrophoretic mobility shift assay. RESULTS: (1) IL-8 production and IL-8 mRNA expression induced by TNF-? was blocked by pyrrolidine dithiocarbamate (PDTC). (2) TNF-? triggered the activation and translocation of NF-?B and PDTC inhibited the activation of NF-?B induced by TNF-?. CONCLUSION: The induction of IL-8 gene and protein by TNF-? is dependent on the activation of NF-?B. Antioxidants may inhibit the induction of IL-8 gene and protein through inhibiting NF-?B activation.
