Objective:To investigate the expression of tissue factor pathway inhibitor-2 (TFPI-2) and synuclein gamma (SNCG) in esophageal cancer and their correlation with local invasion, lymph node metastasis and apoptosis. Methods:The expression of TFPI-2, SNCG, and matrix metalloproteinase-9 (MMP-9) was detected by immunohistochemical SP methods in 82 cases of esophageal cancer tissues, 20 cases of atypical hyperplasia tissues, and 54 cases of para-cancerous tissues. The apoptosis of esophageal cancer cells was detected by TUNEL staining and apoptosis index (AI) was calculated. Results:The positive rates were 30.4%, 60.0%, and 87.0% for TFPI-2 protein and 63.4%, 30.0%, and 3.7% for SNCG protein in the tumor tissues, atypical hyperplasia tissues,and tumor-adjacent normal tissues, respectively. There was a significant difference between the three groups(P<0.01). The positive expression of TFPI-2 and SNCG correlated with the lymph node metastasis, invasion depth, TNM staging, and differentiation degree of esophageal cancer (P<0.01), but did not correlate with age at surgery, gender, tumor location, and pathologic classification(P>0.05). The expression of TFPI-2 and MMP-9 was negatively correlated (r=-0.636, P=0.000). The expression of SNCG and MMP-9 was positively correlated(r=0.393,P=0.000). AI was related with TFPI-2 and SNCG expression (P<0.05). Conclusion:TFPI-2 not only inhibited the expression of MMP-9 but also induces apoptosis of esophageal cancer to prevent tumor invasion and metastasis, however, SNCG plays a contradictory role in cancer development. TFPI-2 and SNCG might serve as new tumor markers and the new targets for tumor gene therapy.

To study the effects of conjee and cooked rice on postprandial glucose and plasma insulin levels in type 2 diatetes,and to help diabetic patients select reasonably food.41 diabetes were divided into cooked rice group ( group A),conjee with steamed bread group ( group B),and oatmeal group ( group C ).At 1 h after meal,the values of postprandial plasma glucose (PPG) was significantly lower in group C than those in group A and group B [ ( 11.17± 2.30 vs 12.88 ± 1.29,13.29 ± 1.97 ) mmol/L,P ＜ 0.05 ].At 2 h after meal,the value of PPG was significantly lower in group C than in group A [ ( 8.88 ± 2.66 vs 10.87 ± 1.63 ) mmol/L,P ＜0.05 ].At 1 h and 2 h after meal,there was no significant difference between the value of PPG in goup A and group B ( P＞0.05 ).At 1 h after meal,the value of plasma insulin was significantly lower in group C than those in group B [ (46.02 ± 26.32 vs 88.56 ± 68.75 )μU/ml,P ＜0.05 ],and there was a littler higher in group B than group A ( P＞0.05 ).At 2 h after meal,there was no statistical difference of plasma insulin among group A,B,C [ ( 57.10 ± 33.56,62.26 ± 24.42,54.16 ± 41.35 )μU/ml,P＞0.05 ) ].Isocaloric oat food is potentially beneficial in sustaining blood glucose status and decreasing insulin secretion.It is the ideal choice for type 2 diabetes.Meanwhile,there were no statistical differences in PPG and insulin levels between the individuals taking conjee with steam bread and cooked rice.

1H NMR metabonomics approach was used to reveal the chemical difference of urine between patients with Xiao-Chaihu Tang syndrome (XCHTS) and healthy participants (HP). The partial least square method was used to establish a model to distinguish the patients with Xiao-Chaihu-Tang syndrome from the healthy controls. Thirty-four endogenous metabolites were identified in the 1H NMR spectrum, and orthogonal partial least squares discriminant analysis showed the urine of patients with Xiao-Chaihu Tang syndrome and healthy participants could be separated clearly. It is indicated that the metabolic profiling of patients with Xiao-Chaihu Tang syndrome was changed obviously. Fifteen metabolites were found by S-pot of OPLS-DA and VIP value. The contents of leucine, formic acid, glycine, hippuric acid and uracil increased in the urine of patients, while threonine, 2-hydroxyisobutyrate, acetamide, 2-oxoglutarate, citric acid, dimethylamine, malonic acid, betaine, trimethylamine oxide, phenylacetyl glycine, and uridine decreased. These metabolites involve the intestinal microbial balance, energy metabolism and amino acid metabolism pathways, which is related with the major symptom of Xiao-Chaihu Tang syndrome. The patients with Xiao-Chaihu Tang syndrome could be identified and predicted correctly using the established partial least squares model. This study could be served as the basis for the accurate diagnostic and reasonable administration of Xiao-Chaihu-Tang syndrome.

OBJECTIVETo investigate the inhibition effect of curcumin on the proliferation of the human esophageal carcinoma cell line Ec109 and its impact on PEN/PI3K/Akt signaling pathway.

METHODSEsophageal carcinoma Ec109 cells were cultured in vitro conventionally and were treated with curcumin at different concentrations. The cell proliferation level was examined by MIT colorimetry, the ultrastructure of curcumin-treated Ec109 cells were detected with transmission electron microscope (TEM) and cell apoptosis was observed by FCM with AnnexinV-FITC/PI double staining. The protein levels of PTEN, Akt, GSK3P and Caspase 3 of curcumin-treated Ec109 cells were detected by Western blot.

RESULTSMTT test showed that curcumin could inhibit the proliferation of Ec109 cells in a time and concentration-dependent manner. TEM examination indicated that curcumin could induce Ec109 cell apoptosis. FCM detection showed that Ec109 cell apoptotic rate increased significantly with the increase of drug concentration. On the other hand, curcumin could promote the expression of PTEN, GSK3beta and Caspase 3 yet reduce the expression of Akt.

CONCLUSIONCurcumin could obviously up-regulate the expression of PTEN, GSK3beta and Caspase 3, surpress PI3K/Akt signaling pathway and hence inhibit the proliferation of Ec109 cells.

ObjectiveTo evaluate the curative effect difference between Tong's anterior mesh suspension and modified tension-free vaginal tape-obturator (TVT-O). Methods75 SUI cases were random divided into two groups: Group A (35 cases) were accepted Tong's anterior mesh suspension and group B (40cases) were accepted modified tension-free vaginal tape- obturator. Curative effects, operation safety,and complications and so on, were recorded and compared. ResultsThere had no statistical differences between these two groups on operation time, bleeding lose, operation injury, immediate postoperative urinary retention andcure rates, but the operation expense of group A was cheaper than group B [ (980. 74 ±212.45)yuan vs (2879.06 ±467. 13)yuan , P ＜0.05). ConclusionThe curative effect between two methods were similar. It's a little complicated and fit to be popularized in large hospital to modified tensionfree vaginal tape-obturator. Tong's anterior mesh suspension was performed under completely direct vision,not through pelvic cavity, and it was an economic, convenient and easy way, which not only fit to be popularized in basic hospital, but also a surgical remedial measure to the failures who accepted these operations,such as TVT, SPARC, IVS, MONARC, TOT, TVT-O, etc.

Objective To evaluate the CT findings of pancreatic carcinoid tumors.Methods The CT imaging data of five patients with pancreatic carcinoid tumors confirmed by pathology were retrospectively analyzed.Results The tumors ranged in maximum diameter from 2.0 to 11.0 cm with a mean of 6.4 cm. On unenhanced CT,the tumors were slightly hypodense relative to the pancreatic parenchyma,homogenous in 2 cases,and heterogenous in 3 cases.One tumor showed calcification.After contrast material injection, the solid component of the tumor showed marked heterogenous enhancement on the arterial phase scanning in 3 cases,and mild heterogenous enhancement in 2 cases.The degree of tumor enhancement was less intense than the surrounding pancreatic parenchyma due to necrosis of various degree,which led to the cystic appearance of the tumor in 1 ease.On the portal phase scanning,all tumors showed marked enhancement similar to that of the pancreatic parenchyma.On the delayed phase scanning,the degree of enhancement was more intense than the surrounding pancreatic parenchyma in 1 case.Liver metastases with retroperitoneal lymphadenopathy and peripancreatic vessels invasion were seen in 1 case.No dilatation of the biliary tract or pancreatic duct was present.Conclusion The CT features of pancreatic carcinoid tumors included infrequent dilatation of the biliary tract or pancreatic duct and unusual vascular involvement,calcification within the mass,marked enhancement similar to that of the surrounding pancreatic parenchyma during the portal phase scanning and more intense during the delayed phase scanning.

OBJECTIVETo optimize primarily acupuncture program for dysphagia after cerebral infarction.

METHODSSixty-three patients with pseudobulbar palsy dysphasia after cerebral infarction were selected as the subjects. Water swallow test was adopted for observation index. Orthogonal design was used to study the different combinations of treatment programs among four factors and three levels, named acupuncture opportunity (factor A: A1: 1-10 d, A2: 11-20 d, A3: 21-40 d), point combination (factor B: B1: points in the neck, B2: points in the neck + points in the glossopharyngeal part, B3: points in the neck + points in the glossopharyngeal part + differentiating point), needling depth (factor C: C1: shallow puncture, C2: moderate puncture, C3: deep puncture), and treatment session (factor D: D1: 2 sessions, D2: 4 sessions, D3: 6 sessions); as well as the influences on pseudobulbar palsy dysphagia after cerebral infarction so as to determine primarily the optimized acupuncture program for dysphagia after cerebral infarction.

RESULTSThe direct analysis of orthogonal design indicated that the best level and the combination of four factors and three levels were A1 (or A2), B3, C3 and D3. It meant that for the patients less than 20 days for sickness, the points in the neck, points in the glossopharyngeal part and points selected according to syndrome differentiation were selected for deep puncture and the treatment lasted for 6 sessions. This program achieved the best improvement in water swallow test. The comparison between the primary effect and secondary effect among four factors (variance analysis) showed that factor A and C were the significant factors (P < 0.05), factor B and D were not significant (P > 0.05). It was suggested that acupuncture opportunity and needling depth played the significant roles in clinical efficacy. The comparison among different levels in terms of the significant factors A and C (multiple comparison) presented that A1 and A2 were superiorly significant than A3 (P < 0.001), A1 was not different in significance from A2 (P > 0.05). C3 was superiorly significant than C2 and C1 (P < 0.001, P < 0.01) and C2 was superiorly significant than C1 (P < 0.05).

CONCLUSIONBy the comprehensive summarization of direct analysis, variance analysis and multiple comparison combined with actual clinical situation, the optimal program of acupuncture treatment for pseudobulbar palsy dysphasia after cerebral infarction is that in terms of the four factors and three levels, for the patients within 1 to 20 days for sickness, acupuncture is applied to the points in the neck or combined with points in the glossopbaryngeal part or the points se-i lected according to syndrome differentiation, with deep puncture, for 4 to 6 sessions of treatment.
