Methods A total of 53 lung cancer patients with malignant pleural effusion were randomly divided into two groups: BCG PSN combined with chemotherapy group (treatment group, 27 patients) and simple chemotherapy group (control group, 26 patients). Drugs were injected into thoracic cavity, which was repeated every 7 day interval. Effective rate, Karnofsky score and toxicities were evaluated. Results After treatment, the effective rate was 88.8% in treatment group and 53 9% in the control group. Significant difference was found in the two groups( P

Objective To observe pathological changes of varicose veins after electrocoagulation and endovenous laser treatment(EVLT) and to compare the efficacy between electrocoagulation and EVLT for the treatment of varicose veins of the lower extremity.Methods Twenty patients with varicose veins of the lower extremity were treated with either electrocoagulation(n=10) or EVLT(n=10).Histopathological changes of varicose veins were observed.Eight dogs were randomly divided into 2 groups and treated with electrocoagulation or EVLT.The treated veins were taken out at 0,7,and 14 days after operation,for histopathological examinations.Results After electrocoagulation or EVLT,the endothelial cells of varicose veins were absent,the structure of smooth muscle cells was indistinct,broken collagenous fibers and elastic fibers were observed,and thrombosis leading to occlusion was observed in the lumen.Incomplete thrombus organization and conglutination with the walls were observed 7 days after operation.Mild recanalization was found in both groups.On the 14th postoperative day,the hyperplasia of smooth muscle cells,collagenous fibers,and elastic fibers was detected.Complete thrombus organization was seen,and recanalization presented no obvious changes.ConclusionsBoth electrocoagulation and EVLT can lead to the occlusion of varicose veins,being effective therapeutic alternatives for varicose veins of the lower extremity.

AIM:To develop a new method to determine cucurbitacin B in Pedicellus Melo by capillary zone(electrophoresis(CZE).) METHODS:All the samples were analysed on a fused silica capillary(75 cm?75 ?m I.D.) by using 50 mmol/L sodium borate solution(containing 5% acetonitrile) as the background electrolyte with the running voltage at 12.0 kV and detection wavelength of 265 nm.And clorprenaline hydrochloride was applied as the internal standard. RESULTS:The results showed a good linear correlation between relative peak area of cucurbitacin B(y) and its concentration(x) over the range of 0.15～1.2 mg/mL.Regression equation was y=(0.003 4x)+0.058,r=0.999 7,and the average recovery for baicalin was 100.2% with the RSD at(2.11%). CONCLUSION:The method is rapid,simple,reproducible and produces low pollution.It serves as a novel way to determine cucurbitacin B.

Objective To explore the expression level of calmodulin (CaM) in non-small cell lung carcinoma (NSCLC) and its clinical significance. Methods The expression levels of CaM and CaM mRNA were detected in 64 human NSCLC samples by immunohistochemistry and in situ hybridization, respectively. Results The positive rates of CaM mRNA and CaM protein were 60.4% and 65.6%, respectively. The positive rates of CaM mRNA in low-differentiated samples were significantly higher (70.0%) than those in moderate- to well-differentiated samples (45.3%). The expression rates of CaM in Ⅲ-Ⅳ stages (81.8%) were significantly higher than those inⅠ-Ⅱstages (51.6%) (P

Objective To explore the relationship of the expression levels of laminin (LN) and calmodulin (CaM) in non-small cell lung carcinoma (NSCLC) with its metastasis and prognosis. Methods The expressions of CaM and LN were detected in 64 human NSCLC samples by immunohistochemistry. Results The expressions of LN and CaM were closely associated with the differentiation and the grades of NSCLC as well as the lymph node metastasis. The positive rates of LN in adenocarcinoma and squamous cell carcinoma were 45.1% and 69.7 (P0.05), respectively. The positive rate of LN protein in low-differentiated samples (36.6%) was significantly lower than that in moderate- to well-differentiated samples (61.7%), but the positive rates of CaM were 73.3% in low-differentiated samples and 41.1% in moderate- to well-differentiated samples (P

AIM: A capillary electrophoresis fingerprints(CEFP) method of Fructus Gardeniae was established to evaluate its quality. METHODS: The background electrolyte(BGE) was 25 mmol/L sodium borate solution containing 10% acetonitrile.The detection wavelength was 228 nm and 24 kV was applied.Fructus Gardeniae was extracted by water and injectded for 15 s(9 cm).Some parameters were used to evaluate the similarities.(RESULTS): 24 co-possessing peaks were selected as the fingerprint peaks of Fructus Gardeniae taking chlorogenic acid peak as the reference peak.The similarities between each of the ten places and the standard CEFP of Fructus Gardeniae were evaluated both qualitatively and quantitatively.The CEFP was also evaluated by the information index(I) and the relative information index(I_r). CONCLUSIONS: The CEFP has acceptable precision,reproducibility and can be used to control the quality of Fructus Gardeniae.

Objective To study the change of the expression of cellular growth factor receptor and its effect on the proliferation and migration of vascular smooth muscle cells (VSMCs) under electrical field. Methods 1) A electrophoresis apparatus was designed for applying the direct current electric fields to the cultured VSMCs, which were separated from the aorta of rats. Interval photographs were used to analyse the direction and distance of VSMCs migration. Cellular growth factors such as platelet derived growth factor receptor (PDGFR), angiotensin II type 1 receptor (AT1R) and its type 2 receptor(AT2R) were studied by immunohistochemistry or immunofluorescence to show the mechanism relation to the migration of VSMCs. Results Under the direct current electric field, the expression of PDGFR was increased obviously and distributed asymmetricly on the membrane of VSMCs. The receptor mainly focused on the cathode side of cellular membrane in electric field. The AT1R were also enhanced in the cells after exposure to the electric field, but the expression of AT2R was uncharged. The longer exposure time to the 150 mV/mm electric field, the more electrotaxis the cells showed. The distance of cellular migration increased obviously with the time to exposure the electric field comparing with the control group. There was no significant difference in the expression of proliferating cell nuclear antigen (PCNA) between two groups. Conclusion External electric fields applying to the rat VSMCs can change the growth characteristic and enhance directional migration of VSMCs. These effects maybe related to the up-regulated expression and re-distribution of some cellular growth factors such as PDGFR, AT1R and AT2R.
