Objective To investigate the expression of PTPN13 in human gastric cancer and gastric cancer SGC-7901celllineanditsassociationwithproliferationandinvasion.Methods 106casesgastriccancertissuesamples and matched normal peritumorial tissues were collected .SGC-7901 cells were cultured and divided into two groups including pcDNA3.1-PTPN13 transfection group and without transfection group .Immunohistochemical technique was used to detecte protein expression of PTPN 13.The association of PTPN13 expression with tumor location , tumor size , depth of invasion and tumor metastasis were analyzed .The survival rate of patients with different PT-PN13 expression was calculated by Kaplan-Meier curves.CCK-8 assay was used to estimate the proliferation chan-ges.Using Trans-well assay analyzed the invasion of SGC-7901 cells.Moreover, Western blot was performed to de-tect the markers of EMT including E-cadherin, Snail and MMP9.Results Immunohistochemistry showed the expression rate of PTPN13 in gastric cancer tissues was lower than normal tissue (31 %vs 83%, P<0.05).The expression of PTPN13 in patients was related to with different tumor size , depth of invasion and tumor metastasis (P<0.05).The 2-year survival rate of patients with negative PTPN13 expression were lower.Overexpression reduced both proliferation and invasion in SGC-7901 cells.Up-regulated PTPN13 may increase E-cadherin level but decreases the level of Snail and MMP9 .Conclusions PTPN13 plays a role in gastric cancer tissue and cells as a tumor suppressor.Lower PTPN13 may predict a poor prognosis.PTPN13 may be used as therapy target in gastric cancer.

A patient diagnosed with myoepithelial carcinoma was recently treated in our department. The neoplasm was huge, located in the left maxillofacial region, blocking both eyes, impeding feeding. About one month before admission, the tumor began to bleed frequently, about 100 ml each time, causing headache, dizziness, fatigue, and cold sweats. CT showed the maximum diameter of the tumor was about 23 cm, with uneven density, and maxillofacial bone destruction. MRI revealed internal bleeding and necrosis inside the tumor. After admission, blood routine test showed erythrocyte count 3.64 x 10(12)/L(↓), hemoglobin 106 g/L(↓), hematocrit 0.320 (↓), serum iron 6.2 μmol/L(↓). After surgery, the patient recovered smoothly.

Seven sinapine analogs (6a-6g) were synthesized using cinnamon acid or benzoic acid and their derivatives as starting materials, which obtained from substituted benzaldehyde and malonate. The structures of target compounds were characterized by IR, 1H NMR and elemental analysis. The effects of compounds 6a-6g on the smooth muscle of intestine isolated from rabbit were studied, and the experimental results showed that compounds 6a, 6d and 6g had diastolic action, while 6f had contractile action.

AIM: To establish a RP-HPLC method for determining ephedrina hydrochloridum and pseudoephedrine hydrochloride in Chuanliting Spray(Herba Ephedrae,Folium Artenisiae argyi,Radix et Rhizoma Asari,etc.). METHODS: HPLC conditions were as follows: C_(18)(4.6 mm?250mm,5?m) column,0.2% phosphoric acid—acetonitrile(96∶4) as mobile phase with flow rate of 1mL/min,and the detection wavelength at 205nm.(RESULTS:) The calibration curve of ephedrina hydrochloridum was linear between 0.448-3.416?g(r=(0.999 8,) n=7).The average recovery was 100.26% and RSD=2.17%(n=5).The calibration curve of pseudoephedrine hydrochloride was linear between 0.16-1.12?g(r= 0.999 1,n=7).The average recovery was 101.60% and RSD =2.19%(n=5). CONCLUSION: The method is convenient and efficient,and can be used for quantitative analysis and quality control of this preparation.

Objective To establish a method for the determination of Puerarin in Huanglian Jiangtang Tablets. Methods The sample was extracted with 30 %ethanol. The chromatographic conditions were as follows:Diamonsil C18 chromatographic column(250 mm?4.6 mm,5?m)with a mobile phase of acetonitrile-0.5 %glacial acetic acid,the detection wavelength being at 250 nm and the flow rate being 1.0 mL?min-1. Results A linearity was obtained from 0.338 ?g to 2.336 ?g of Puerarin in Huanglian Jiangtang Tablets with a good correlation (r=0.999997,n=7).The average recovery was 100.2% and RSD=1.80%(n=6). Conclusion This method for determination of Puerarin in Huanglian Jiangtang Tablets is easy,sensitive,specific and accurate.

Objective To assess the value of video-assisted thoracoscopic mini-invasive lobectomy in the treatment of pulmonary benign lesions or malignancies. Methods A retrospectively analysis on clinical data of 35 cases of video-assisted thoracoscopic mini-invasive lobectomy, which were performed from February 2002 to June 2006, was made. The pathological diagnosis included 31 cases of peripheral lung cancer (T_1N_0-1M_0), 3 cases of bronchiectasis, and 1 case of atelectasis combined with pulmonary abscess. The procedures included 30 cases of anatomical lobectomy and 5 cases of non-anatomical lobectomy. Results No conversion to open surgery was required. The operation time was 85~210 min (115?35 min) and the intraoperative blood loss was 150~450 ml (210?55 ml). Postoperatively, acute respiratory failure was encountered in 2 cases, and mechanical ventilation was given for 3 and 5 days, respectively. Acute myocardial infarction occurred in 1 case, which was cured by early-stage thrombolysis. No postoperative complications were seen in the remaining 32 cases. The closed chest drainage was maintained for 2~10 days (mean, 5.4 days). In 3 cases of pulmonary benign lesions, follow-up checkups for 41, 33, and 13 months, respectively, found no long-term complications. In 25 cases of lung cancer, follow-up observations were made for 3~53 months (mean, 15.2 months), including 3~12 month in 6 cases, 12~24 months in 9 cases, 24~36 months in 7 cases, and 36~53 months in 3 cases. There were 4 cases of death due to cancer recurrence or metastasis (16%), 2 cases of with-tumor survival (8%), and 19 cases of disease-free survival (76%), respectively. Conclusions Video-assisted thoracoscopic mini-invasive lobectomy is a feasible and safe procedure for peripheral lung cancer and benign lung diseases.
