Objective To examine the expressions of FHIT gene and HER_2 in non-small cell lung cancer(NSCLC)and the relationship between the expressions and the clinicopathological features of NSCLC, and to investigate the relationship between FHIT protein and HER_2 expression. Methods FHIT protein and HER_2 expressions in 50 lung cancer cases and 21 adjacent non-cancer tissues were performed by immunohistochemistry. And the positive rates of FHIT and HER_2 were measured. Results The positive rates of FHIT protein were 30.00% in lung cancer tissues. The expression levels of FHIT were significantly lower in lung cancer tissues than that in non-cancer lung tissues (P

The effects of Guizhi Fuling capsule and its active ingredient combination within different concentration on SPL proliferate were observed by MTT method. The ratio of CD80/86, CD3CD25 and CD3CD69 was used to evaluate cell activation effects of Guizhi Fuling capsule and its active ingredient combination by FCM. Guizhi Fuling capsule with concentration of 400 mg · L(-1)can promote spleen lymphocyte proliferation, as well as the active ingredient combination, which showed the obvious dose-effect relationship. Compared with control group, the difference has statistical significance (P≤0.01). The result of FCM showed that Guizhi Fuling capsule and its active ingredient combination can promote CD80 and CD86 expression on spleen lymphocyte, and also can increase CD25 and CD69 ratio between spleen CD3+ cells. Compared with control group, the difference has statistical significance (P≤0.01). Thus, Guizhi Fuling capsule and its active ingredient combination may have immune-modulate effects, and the mechanism may have a close relationship with the lymphocyte activation.

OBJECTIVETo evaluate the outcomes of T3a prostate cancer with unfavorable prognostic factors treated with permanent interstitial brachytherapy combined with external radiotherapy and hormone therapy.
METHODSFrom January 2003 to December 2008, 38 patients classified as T3a prostate cancer with unfavorable prognostic factors were treated with trimodality therapy (brachytherapy + external radiotherapy + hormone therapy). The prescription dose of brachytherapy and external radiotherapy were 110 Gy and 45 Gy, respectively. The duration of hormone therapy was 2-3 years. The endpoints of this study included biochemical failure-free survival (BFFS), distant metastasis-free survival (DMFS), cancer-specific survival (CSS), and overall survival (OS). Survival curves were calculated using the Kaplan-Meier method. The Log-rank test was used to identify the prognostic predictors for univariate analysis.
RESULTSThe median follow-up was 71 months. The serum pre-treatment prostate-specific antigen (PSA) level ranged from 10.0 to 99.8 ng/ml (mean 56.3 ng/ml), the Gleason score ranged from 5 to 9 (median 8), and the percentage of positive biopsy cores ranged from 10% to 100% (mean 65%). The 5-year BFFS, DMFS, CSS, and OS rates were 44%, 69%, 82%, and 76%, respectively. All biochemical failures occurred within 40 months. The percentage of positive biopsy cores was significantly correlated with BFFS, DMFS, and OS (all P=0.000), and the Gleason score with DMFS (P=0.000) and OS (P=0.001).
CONCLUSIONST3a prostate cancer with unfavorable prognostic factors presents not so optimistic outcome. Hormone therapy should be applied to prolong the biochemical progression-free or metastasis-free survival. The percentage of positive biopsy cores and the Gleason score are significant prognostic factors.

Objective To evaluate the serum prostate specific antigen(PSA)change after I-125 radioactive seed implantation without androgen ablation therapy for prostate cancer,Methods A total of 13 patients with prostate cancer were included.The clinical stage was T_(1c)N_0M_0 in 8 cases,and T_(2a)N_0M_0 in 5. The Gleason scores were 5 in 4 cases and 6 in 9.The mean serum PSA was 8.2 ng/ml(range,2.8-14.6 ng/ml).I-125 seed implantation(D90=140-155 Gy)was performed.Serum PSA was monitored every month for the first 3 months and every 3 months for the next 20 months.Results The range of follow-up time was 3-23 months.At 1,2,3,6,9,12,15,18 and 21 months after implantation,the median serum PSA values were 6.7,5.0,2.7,1.6,1.2,0.9,0.8,0.8 and 0.7 ng/ml;and the median percentage change in ser- um PSA were 72%,51%,29%,20%,13%,11%,9%,9% and 8%,respectively.One month after brachy- therapy,30% of the patients had fluctuation in PSA.Conclusions Compared with radical prostatectomy and androgen ablation therapy,the rate of PSA decline is slower with fluctuation at early phase.The most sig- nificant decline of PSA occurs in the first 12 months,especially in the first 3 months after I-125 seed implan- tation.

AlM:To evaluate the efficacy of combined pranoprofen eye drops and artificial tears on the treatment of mild to moderate dry eye syndrome after trabbeculectomy.METHODS:This prospective case control study included 63 cases (63 eyes) of patients with mild to moderate dry eye syndrome after trabbeculectomy in our hospital from November 2013 to June 2013. All subjects were randomly divided into two groups. Observation group was treated with combined pranoprofen eye drops and artificial tears and control group received simple artificial tears marking the eyes at 1, 2, 4wk. The patient's symptoms, signs, BUT, S▏t, and FL were observed before treatment and 1, 2, 4wk after treatment.RESULTS: After 2wk, the symptoms of observation group were improved, there was statistically significant difference (P<0. 05). FL difference of each group was statistically significant ( P<0. 05 ); After 4wk, symptoms and signs were improved. There was statistically significant difference ( P < 0. 05 ). The BUT of the observation group and corneal FL scores of two groups showed significant differences (P<0. 05). CONCLUSlON: Artificial tears joint pranoprofen eye drops has good curative effect in the treatment of mild to moderate dry eye syndrome after trabbeculectomy.

OBJECTIVETo study effects of a combined regime of auricular-plaster and body acupuncture in treatment of cervical spondylosis of vertebral artery type and make a preliminary revelation of the mechanism.
METHODSNinety-two patients were randomly divided into 2 groups, the treatment group (n = 56) received the combined regime of auricular-plaster and body acupuncture, and the control group (n = 36) received treatment with body acupuncture. Clinical symptoms and signs, therapeutic effect and some indexes about vertebrobasilar hema-kinetics and hema-rheology were investigated before and after treatment.
RESULTSThe treatment group was better than the control group in the clinical overall effective rate (89.29%) and the clinically control rate (17. 85%), and in improving the following indexes, including dizziness and headache, the vertebrobasilar volume and rate of blood flow etab and IR (P < 0.05).
CONCLUSIONSA combined regime of auricular-plaster and body acupuncture ameliorates not only main signs but also some indexes about vertebrobasilar hema-kinetics and hema-rheology. This treatment is an effective therapy for cervical spondylosis of vertebral artery type both in Malaysia and in China.
