AIM:To investigate the changes of apoptosis and activation of I??-? induced by vinblastine via the blockage of caspase-3 signal transduction pathway, and to explore the possible mechanism of signal transduction pathway involving in the vinblastine-induced apoptosis. METHODS: The breast cancer cell lines Bcap37 were treated with different concentrations of vinblatine dissolved in dimethyl sulphoxide (DMSO) or caspase-3 inhibitor (DEVD-CHO, 100 ?mol/L) for 3 h. The changes of the proliferation were detected by MTT methods. The apoptosis was determined by observing the internucleosomal DNA cleavage and PI staining, and the proteins of pro-caspase-3 and I??-? were detected by Western blotting methods. RESULTS: The results showed that vinblastine induced the pro-caspase-3 degradation. The significantly attenuation of vinblastine-induced apoptosis in breast cancer cell line by caspase-3 inhibitor DEVD-CHO was verified by MTT assay, internucleosomal DNA cleavage and flow cytometry PI staining analysis. The IC50 was 56.8 ?mol/L and 87.4 ?mol/L respectively for two groups. The inhibition of vinblastine-induced phosphorylated degradation of I??-? was also observed by DEVD-CHO. CONCLUSION: Based on these finding, vinblastine induces apoptosis in breast cancer cells via NF-??/I?? signal transduction pathway, which is co-operated by caspase signal pathway. Through the blockage of caspase pathway with caspase-3 inhibitor, vinblastine-induced apoptosis and the phosphorylated degradation of I??-? in breast cancer cells are suppressed greatly.

AIM: To compare the effects of different surgeries in the treatment of angle closure glaucoma with cataract and the improvement of quality of life.METHODS: The clinical data of 60 cases (60 eyes) with angle closure glaucoma and cataract who were admitted to the hospital between January 2014 and October 2016 were collected.According to the surgical method, they were divided into the control group (simple trabeculectomy, n=28) and the observation group (trabeculectomy combined with phacoemulsification and intraocular lens implantation, n=32).The changes of visual acuity and intraocular pressure before and after surgery were compared between the two groups.The incidence of postoperative complications was statistically analyzed, and the quality of life was compared between the two groups.RESULTS: Before surgery, there was no significant difference in visual acuity, intraocular pressure and anterior chamber depth between the two groups (P>0.05).At 4wk after surgery, the visual acuity of two groups increased and intraocular pressure decreased.The anterior chamber depth of observation group increased while that of the control group decreased (P<0.05).At 4wk after surgery, the visual acuity and anterior chamber depth of observation group were higher than that of the control group but intraocular pressure was lower than that of control group (P<0.05).The success rate of surgery and the opening rate of chamber angle after surgery in the observation group were higher than those in the control group (P>0.05).The incidence of postoperative complications in the observation group was lower than that in the control group (P<0.05).Before surgery, there was no statistically significant difference in quality of life score between the two groups (P>0.05).At 4wk and 3mo after surgery, the scores of the two groups increased (P<0.05), and the quality of life scores of observation group were higher than those of the control group at different time (P< 0.05).CONCLUSION: The success rate of trabeculectomy combined with phacoemulsification and intraocular lens implantation is high in the treatment of angle closure glaucoma with cataract.The regimen can improve the visual function, reduce the incidence of postoperative complications, and improve the quality of life of patients.

Objective To evaluate the prognostic value of iASPP for nasopharyngeal carcinoma (NPC).Methods One hundred and thirty patients with nasopharyngeal carcinoma were initially diagnosed and treated between January and December 2012 in Department of Radiation Oncology of the First Affiliated Hospital of Guangxi Medical University.The clinical staging was classified according to the cancer staging criteria 2009 AJCC/UICC.All patients were treated by IMRT.Cisplatin-based concurrent chemotherapy was given to patients with stages Ⅲ-ⅣB disease.Immunohistochemistry was used to detect the expression of iASPP in the carcinoma tissues,and the clinicopathological features were compared among the patients with different expressions of iASPP.Furthermore,the relationship between the expression of iASPP and the efficacy in patients was explored.Results Of 130 patients,positive expression of iASPP was observed in 86 patients (66.2％),and negative expression in 44 patients (33.8％).There was significant difference in the positive expression rate of iASPP among the patients with different N-stage and clinical stages(x2 =7.565,4.947,P ＜ 0.01).At three months after treatment,no significant difference was found in the response rate of tumor with different expression of iASPP.In univariate analysis,the expression of iASPP was significant predictor of 3 year-DMFS (x2 =4.335,P =0.037) and PFS (x2 =6.640,P =0.01).Furthermore,N-stage was significant predictor of 3y-DMFS (x2 =8.058,P =0.005),PFS (x2 =9.554,P =0.002) and OS (x2 =6.987,P =0.008),respectively.By using multivariate Cox analysis,the expression of iASPP and N-stage was independent prognostic factors for PFS (x2 =4.336,5.228,P ＜ 0.05),respectively.Conclusions Positive expression of iASPP may be a poor prognostic factor for NPC patients.

Objective:Studies suggested that some growth factors and their receptors play important roles in the treatment and prognosis of lung cancer.In this study we investigated the expression of epidermal growth factor receptor(EGFR),vascular endothelial growth factor(VEGF),and Ki-67 simultaneously in the tissues of aged patients with non-small cell lung cancer(NSCLC). Methods:The expression levels of EGFR,VEGF,and Ki-67 in 64 cases of aged patients with NSCLC were detected by immunohistochemistry staining.Results:The positive expression of EGFR,VEGF and Ki-67 in the tissue of lung cancer was 59.4%,57.8% and 92.2%,respectively.It is different significantly while compared with control group of benign tissues.The expression levels of EGFR and VEGF are correlated significantly with the pathologic type,differential degree,TNM stage and lymphatic metastasis.The expression level of Ki-67 is related to differential degree and TNM stage of lung cancer.Conclusion:The method of immunohistochemistry to detect multiple biological markers simultaneously is simple and feasible.It can supply important information for the staging and prognoses of patients with NSCLC,and more than that,it can also provide the theoretic basis for the individualized molecular targeting therapy of NSCLC.

Objective:To provide reference for the treatment of lipoprotein glomerulopathy and to investigate the participation of clinical pharmacists in the whole treatment course. Methods: Three different treatment regimens, including immunosuppressive thera-py, dual plasma filtration therapy and lipid-lowering combined with reducing urinary protein therapy was respectively adopted for one patient with lipoprotein glomerulopathy, and the efficacy was evaluated. Clinical pharmacists assisted physicians in deciding treatment regimen, performed pharmaceutical care, adjusted medication and analyzed the prognosis of the patient during the follow-up. Results:1. Immunosuppressive therapy was ineffective for the patient;2. The dual filtration acted quickly, while the expense was high and the disease was easy to relapse;3. The third therapy was relatively safer and more economical with long-term effect. Conclusion:Combi-nation therapy of lowering lipid and reducing urinary protein is the most suitable treatment regimen for the patient with lipoprotein glo-merulopathy. Clinical pharmacists play an important role in the whole course of treatment to assist physicians in obtaining the maximum benefit of patients.

Objective To evaluate the clinical effect of vitrectomy for open globe injuries with intraocular foreign bodies in 48 hours after injury.Methods Retrospective analysis was used to evaluate the patients with open globe injuries (OGIs) accompanied by intraocular foreign bodies (IOFB) who underwent vitrectomy of pars plana vitrectomy (PPV) within 48 hours during the period from January 1,2009 to March 1,2015 in our hospital.Results Among the 56 eyes,16 eyes with intraocular foreign bodies occurred endophthalmitis,while the other 40 eyes did not;the intraocular foreign bodies removal rate was 100％.Among all the patient eyes,52 eyes were saved after surgery,while 4 eyes failed.The pars plana vitrectomy operation ratio of the intraocular foreign bodies patients with endophthalmitis and operated within 24 to 48 hours was 2.09 times than that within 24 hours.There was no significant difference in terms of eye preservation,one time of retinal reposition and abnormal intraocular pressure no matter the PPV surgery was conducted within 24 hours or 24 to 48 hours after injury.Conclusion Early vitrectomy is a safe and effective method for the treatment of open globe injuries with intraocular foreign bodies.

OBJECTIVETo explore the effect of Qiling Decoction (QD) combined highly active antiretroviral treatment (HAART) on expression levels of peripheral blood Th17 and Treg cells in HIV/AIDS patients.

METHODSTotally 55 HIV/AIDS patients were randomly assigned to the treatment group (28 cases) and the combination group (27 cases). Besides, 21 HIV negative patients were recruited as the healthy control group. Those in the treatment group received HARRT alone, while those in the combination group received HAART combined QD. The observation lasted for 24 weeks. Meanwhile, according to peripheral blood CD4+ T cell counts before treatment, HIV/AIDS patients were assigned to three subgroups. For patients in subgroup 1, 1 cells/microL < CD4+ T cell counts < or = 100 cells/microL; For patients in subgroup 2, 101 cells/microL < CD4+ T cell counts < or = 200 cells/lL; For patients in subgroup 3, 201 cells/microL < CD4+ T cell counts < or = 350 cells/microL. Expression of peripheral blood Th17 and Treg cells, and number of CD4+ T cell counts were detected using flow cytometry (FCM)in HIV/AIDS patients at the pre-treatment baseline, week 4, 12, and 24, as well as those in the healthy control group.

RESULTSCompared with the healthy control group, CD4+ T cell counts and the baseline expression level of Th17 cells in the peripheral blood of HIV/AIDS patients significantly decreased, the expression level of Treg cells significantly increased P < 0.01). Compared with before treatment in the same group, CD4+ T cell counts all increased at week 4, 12, and 24 in the two treatment groups, showing statistical difference (P < 0.05, P < 0.01). There was no statistical difference in the effective rate at various CD4+ T cell levels between the two groups (P > 0.05). There was no statistical difference in expression levels of Th17 and Treg cells between the combination group and the treatment group at any time point (all P >0.05). The Th17/Treg ration significantly increased in the combination group after 24 weeks of treatment, showing statistical difference when compared with the treatment group (U = 2.135, P = 0.038).

CONCLUSIONQD could improve the immune balance of Th17/Treg cells, which might be one of its mechanisms for improving HIV/AIDS patients' immunity.

OBJECTIVETo explore the effect of dexmedetomidine combined electrical stimulation on cognitive function of neurosurgical diseases patients treated by extracerebral intervention.

METHODSTotally 122 patients with neurosurgical diseases who underwent selective intervention were randomly assigned to the observation group and the control group, 61 cases in each group. Patients in the control group recieved anesthesia by dexmedetomidine. Those in the observation group received electrical stimulation at Baihui (DU20), Yintang ( EX-HN3), and Neiguan (PC6) before dexmedetomidine anesthesia. The cognitive function of patients at preoperative day 1 and postoperative day 1 was respectively evaluated by Mini-Mental State Examinations (MMSE). Serum NSE, S-100β, IL-1β, IL-6, and TNF-α levels were detected in the two groups before intervention and immediately after intervention using ELISA.

RESULTSMMSE scores of two groups were significantly reduced at post-intervention day 1, as compared with one day before intervention. MMSE score of the observation group at post-intervention day 1 was (23.15 ± 1.87) points, significantly higher than that of the control group [ (19.34 ± 1.64) points , (P < 0.05)]. The postoperative cognitive dysfunction (POCD) incidence rate of the observation group was 16.4% (10/61), significantly lower than that of the control group [39.3% (24/61); P < 0.05]. Compared with before intervention, NSE and S-100β protein levels, IL-1β, IL-6 and α-TNF levels of the two groups increased (P < 0.05). Post-intervention NSE and S-100β protein levels, IL-1β, IL-6 and α-TNF levels were significantly lower in the observation group than in the control group (P < 0.05).

CONCLUSIONDexmedetomidine combied electrical stimulation could effectively prevent the occurrence of postoperative cognition, and reduce levels of NSA, S-100β, IL-1β, IL-6 and TNF-α.
