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 efficacy of injection itraconazole in treatment of 17 patients suffering invasive pulmonary fungal infections(IPFI).Methods Seventeen patients suffering IPFI were treated with 200 mg injection itraconazole,twice a day on the first two days,then once a day.During the treatment,the symptoms and signs were recorded.Results The effective rate and mortality in this trial with injection itraconazole were 64.7%(11/17)and 17.6%(3/17)respectively.The severe side effect was not found.Conclusion injection itraconazole is an effective therapy for IPFI.

Objective To investigate the efficacy of electromyographic biofeedback therapy (EMGBFT) in treating dysphagia after stroke.Methods Patients diagnosed with dysphagia after stroke were recruited and randomly divided into a control group (n =22),an electrostimulation group (ES,n =25) and an EMGBFT group (n =23).The control group received conventional treatment,while the patients in the other groups additionally received Vitalstim ES or EMGBFT 5 times per week for 3 weeks.Before and after the trial,deglutition function was evaluated through surface electromyography (sEMG) and using a standardized swallowing assessment (SSA).Results After 3 weeks of treatment,the mean sEMG amplitude,deglutition duration and SSA score and improved significantly in comparison to the baseline in all three groups.All were also significantly better in the two treatment groups than in the control group.Importantly,the mean sEMG amplitude,deglutition duration and SSA score were all significantly better in the EMGBFT group than in the ES group.Conclusion EMGBFT can promote better deglutition among patients with dysphagia after stroke more effectively than ES or conventional treatment.

OBJECTIVE:To bring the computer network into full play in effectively monitoring therapeutic recipe for patients to realize individualized administration of drugs.METHODS:According to the phasic characteristics of forming recipe, a local network model for monitoring therapeutic recipe has been set up.RESULTS & CONCLUSION:By computer and local network monitoring, the quality of prescription can be improved and individualized administration of drugs will further be achieved.

Objective To analyse the femoral head coverage rate of CT in evaluation of Salter osteotomy for developmental dislocation of hip(DDH) in children. Methods Thirty-eight patients with unilateral DDH for Salter osteotomy were enrolled,and X ray photography of pelvis and spiral CT scanning of femoral articulation were performed one week before and 6 months after Salter osteotomy.The femoral head coverage rate of X ray and that of CT were calculated and compared.Another 38 children with normal femoral articulation were served as controls. Results The femoral head coverage rate of X ray was significantly higher than that of CT in patients with DDH(P

Objective To learn the quality of life among coronary artery disease patients after aeteria eoronaria stenting. Methods 50 eoronary artery disease patients after aeteria coronaria stenting were investigated with questionnaires of SF-36 and SAQ before and after 6 months operation. Results Compared with pre-operation, the score of each item in SF-36 and SAQ were improved a lot, the difference was sifnifieant. Conclusions coronary stent implantation can improve quality of life of eardiaopath and is an ideal therapy.

AIM:To observe the changes of tear film on the patients after laser in situ keratomileusis ( LASIK) with corneal flap created by femtosecond laser with Oculus corneal topography.
METHODS:Totally 120 myopic patients (240 eyes) were collected who underwent femtosecond laser surgery LASIK from August to September 2013, and these patients can be followed up for 3mo. Tear break-up time ( BUT) and tear meniscus height ( TMH ) with Oculus corneal topography were recorded preoperatively and postoperatively at 1wk;1, 2 and 3mo.
RESULTS: Oculus BUT: there existed obvious differences (P=0. 012, 0. 000, 0. 023<0. 05) in 1wk, 1 and 2mo compared with the preoperative level. While no such obvious difference ( P = 0. 236 > 0. 05 ) existed in 3mo compared with the preoperative level. TMH:there existed obvious differences (P=0. 025, 0. 019, 0. 026<0. 05) in 1wk, 1 and 2mo compared with the preoperative level. No such obvious difference ( P = 0. 375>0. 05 ) existed in 3mo compared with the preoperative level.
CONCLUSION: Femtosecond laser surgery affects the stability of the tear film at a certain time and a certain extent. The mechanism related to many factors. It is temporary and lighted.

AIM: To observe the changes of tear film on the patients after laser in situ keratomileusis ( LASIK ) with corneal flap created by femtosecond laser with the different gender.
METHODS: The 120 myopic patients ( 240 eyes ) who underwent femtosecond laser surgery LASIK from August to September 2013 were collected, and these patients were followed up for 3mo. The patients were divided into two groups according to the gender, group A was male (110 eyes of 55 patients); group B was female (130 eyes of 65 patients). Dry eye symptom score, tear break-up time ( BUT ) , Schirmer Ⅰ test, corneal fluorescein staining were recorded preoperatively and postoperatively in 1wk,1,2,3mo.
RESULTS: Dry eye symptom score: it was statistically significant between two groups after operation in the 1wk, 1, 2mo(P = 0. 000,0. 023, 0. 030). It had no statistical significance between the two groups in 3mo(P=0. 283). BUT: it was statistical significance between two groups after operation in the 1wk, 1, 2, 3mo ( P= 0. 000, 0. 017, 0.026, 0. 032 ). Schirmer Ⅰ test: it was statistically significant between two groups after operation in the 1wk, 1, 2mo(P = 0. 012,0. 024, 0. 018). It had no statistical significance between the two groups in 3mo ( P=0. 206 ) Corneal fluorescein staining:it was statistically significant between two groups after operation in the 1wk, 1, 2, 3mo (P=0. 022,0. 015, 0. 036, 0.041).
CONCLUSION: The influence of tear film after femtosecond laser surgery for men less than that for women.
