OBJECTIVETo investigate whether bortezomib can enhance the sensitivity of human prostate cancer (PCa) cells to natural killer (NK) cell-mediated cytotoxicity, and whether it produces the same effect on different PCa cell lines.

METHODSWe treated androgen-dependent PCa LNCaP cells and androgen-independent PCa DU145 cells with bortezomib at the concentrations of 0, 5, 10, 15, 20 and 25 nmol/L for 24, 48 and 72 hours, and then detected the proliferation and apoptosis of the tumor cells by CCK-8 and Annexin V/PI, respectively.

RESULTSThe proliferation rates of the DU145 cells treated with 15, 20 and 25 nmol/L bortezomib were (82.79 +/-2.04)%, (73.59+/- 2.95)% and (74.16+/- 6. 16)% at 48 hours and (71.24+/- 5.30)%, (51.20+/- 2.91)% and (38.02+/- 2.67)% at 72 hours, and those of the LNCaP cells were (77.04+/- 7.74)% , (42.61 +/- 6.62)% and (23.85 +/-6.04)% at 48 hours and (36.45 +/-7.02)%, (14.94 +/-5.76)% and (11.65 +/-5. 87)% at 72 hours, both significantly inhibited as compared with the control group (P <0.05). At 24 hours, the apoptosis rates of the DU145 cells treated with 15, 20 and 25 nmol/L bortezomib were (14.41 +/- 1.32)% , (16.13 +/- 1.55)% and (14.48 +/- 1.42)% , and those of the LNCaP cells treated with 20 and 25 nmol/L bortezomib were (12.77 +/- 1.28)% and (14. 84 +/- 1.65)% , significantly higher than those of the control group (P <0.05) , and the DU145 cells showed an even higher sensitivity to bortezomib than the LNCaP cells. Bortezomib failed to sensitize these two cell lines to NK cell-mediated cytotoxicity in short-term assay, while long-term assay manifested that the apoptosis rates of DU145 and LNCaP cells after treated with 20 nmol/L bortezomib + NK cells were (41.83 +/- 5.06)% and (30.31 +/- 3.62)% , respectively, significantly higher

CONCLUSIONBortezomib enhances the sensitivity of than those after treated with either bortezomib or NK cells alone (P <0.05). PCa cells to NK cell-mediated cytotoxicity and adds to the effect of current cancer therapies, and it is more efficacious for androgen-independent prostate cancer.

Objective: To evaluate the therapeutic effects of Tuina and hyperbaric oxygen on prolapse of lumbar intervertebral disc. Methods: The included 160 cases of prolapse of lumbar intervertebral disc were allocated into a treatment group and a control group. The 100 cases in the treatment group were treated with tuina manipulation and hyperbaric oxygen. The 60 cases in the control group were treated with tuina manipulation. The total effect and scores of symptoms and signs were compared before and after treatment. Results: The total effective rate in the treatment group was 100.0%, and 83.0% in the control group. Conclusion: Tuina and hyperbaric oxygen had excellent effects on the prolapse of lumbar intervertebral disc, by improving the clinical symptoms and signs of ache and movement restriction of lower back and leg, and recovering the ability of work and daily life.

Objective To investigate the feasibility of pig lung cancer model induced by bronchial perfusion of 3,4-benzopyrene. Methods 24 experimental pig were randomly divided into model group and control group, each containing 12 cases. Experimental pigs were under the anaesthetic state, pigs in the model group were given endobronchial infusion of 3,4 - benzopyrene - corn oil mixture, pigs in control group were injected with equal capacity of corn oil.Perfusion 1 times a week for 16 weeks.In week 16,32 and 48,all experimental pig were given lung CT scans, then the lung lesions were observed.After 48 weeks, the pig lung, esophagus, and gastrointestinal tract, liver and brain and other organs were dissected, the presence of tumor formation was observed, and the mass, and experimental pig lung biopsy were given hematoxylin and eosin staining analysis. Results Lung cancers were not found in control group by both CT lung cancers and anatomy. In the model group, pulmonary CT showed space-occupying lesions with different location and size in lungs of 8 pigs, and the space-occupying lesions were confirmed as malignant tumors by pathology, including 3 cases of moderately differentiated adenocarcinoma, 2 cases of highly differentiated squamous cell carcinoma, 1 case of alveolar cell carcinoma,2 cases of adenosquamous carcinoma. Three other pigs and pigs in the control group were not found with tumor by both lung CT and anatomy. Pigs in model group were induced successfully to malignant tumor in 1 year , the total tumor formation rate was 75%,lung tumor formation rate was 66.66%. Conclusion The trachea bronchial perfusion of 3,4- benzopyrene is a simple,safe and reliable way to construct animal models of lung cancer.

Methods Seventy-two hours after bilateral ureteral ligation,12 uremic dogs were hemodialyzed for 2 hours,yeilding decreases in plasma urea from (66. 76?13.70) mmol/L to (17. 85?5. 84)mmol/L( P

Objective To investigate the relationship between estrogen replacement therapy and female patients with Alzheimer's risk. Methods We searched the PubMed, Springer, CBM, CNKI, VIP database for studies on the es-trogen replacement therapy and women with Alzheimer's disease, retrieval time from database to 2012 December. We evaluated the methodological quality of the included studies, used RevMan 5.0 software to analyze the extracted data. Results We found seven case-control studies which included 1392 patients and 2719 controls. The meta analysis re-sults show that the proportion of estrogen replacement therapy in AD group is significantly lower than that of the con-trol group, the difference has statistically significant [OR=0.68, 95%CI(0.50,0.90), P=0.01]. Conclusions estrogen re-placement therapy has effects on female patients with Alzheimer's disease, and is a protective factor.

OBJECTIVETo compare the effectiveness and safety of transurethral resection of the prostate (TURP) and transurethral enucleative resection of the prostate (TUERP) in the treatment of benign prostate hyperplasia (BPH).

METHODSA total of 630 BPH patients with indication of surgery were randomly assigned to receive TURP (n = 305) and TUERP (n = 325), respectively. There were no significant differences preoperatively in age, prostate volume, International Prostate Symptom Score (IPSS), and Qmax between the two groups (P > 0.05). The prostate resection rate, operation time, postoperative complications, and quality of life (QOL) of the patients were recorded and statistically analyzed.

RESULTSCompared with TURP, TUERP showed a significantly higher rate of prostate resection ([47.0 +/- 13.3] vs [60.1 +/- 12.3]%, P < 0.05), shorter operation time ([57.9 +/- 15.9] vs [40.4 +/- 14.2] min, P < 0.05), and shorter bladder irrigation time ([2.7 +/- 0.6] vs [2.2 + 1.1] d, P < 0.05). Significant differences were found between the pre- and post-operative levels of serum sodium and hemoglobin in the TURP group ([141.2 +/- 3.5 ] vs [136.9 +/- 4.7] mmol/L, P < 0.01; [137.6 +/- 8.8] vs [124.8 +/- 9.6] g/L, P < 0.01), but not in the TUERP group. Three months after operation, IPSS, QOL, and Qmax were all markedly improved in both groups (P < 0.01), but with no significant differences between the two groups (P >0.05).

CONCLUSIONTUERP is better than TURP in the treatment of BPH for its advantages of higher resection rate of the prostate, shorter operation time and bladder irrigation time, less intraoperative blood loss, fewer postoperative complications, and faster recovery.

Objective To investigate the relationship between Oxfordshire community stroke project(OCSP) classification and imaging classification in acute cerebral infarction. Methods Two hundred and thirty-six patients with acute cerebral infarction were retrospectively evaluated with OCSP classification and imaging characteristics. Results According to OCSP classification,of all the 236 patients with acute cerebral infarction,28(11.9%) experienced total anterior circulation infarction(TACI),71(30.1%) partial anterior circulation infarction(PACI),94(39.8%) lacunar infarction(LACI),and 43(18.2%) posterior circulation infarction(POCI).The consistency was found in 171 cases(72.5%) between the OCSP classification and imaging classification,with the accuracy of 76%(25/33) for TACI,81%(34/42) for PACI,71%(81/114) for LACI and 66%(31/47) for POCI. Conclusion OCSP classification can predict the location and size of cerebral infarction with a high accuracy,and is well consisted with the imaging findings.
