Objective To evaluate the short-term effect of elemene combined with transcatheter hepatic arterial chemoembolization (TACE) interventional therapy for the treatment of moderate and advanced liver cancer.Methods A total of 63 patients with moderate and advanced liver cancer were randomized into test group(31 cases) and control group(32 cases). Both groups were given TACE, and additionally, the test group was given intra-arterial infusion of Elemene Emulsion(400-600 mg/m2)together with MAO(Mitomycin C 4-6 mg/m2 , adriamycin 20-40 mg/m2, Oxaliplatin 50-85 mg /m2), and the control group was given intra-arterial infusion of MAO. Short-term effect was evaluated by the clinical outcomes of tumor size, progression-free survival(PFS), total survival rate and adverse reactio n. Results(1)The overall response rate(ORR) in the test group was superior to that in the control group, and the difference was statistically significant(P<0.05) .(2)PFS in the test group covered 125 days, and that in the control group covered 118 days, the difference being significant (P<0.05); the median survival time(MST) in the test group was 257 days, and that in the control group was 214 days,the difference being insignificant(P>0.05).(3) No severe toxic or side effect was found in t he twogroups, the difference being not significant(P>0.05). The test group tended to have milder adverse reaction. Conclusion Intra-arterial infusion Elemene Emulsion combined with TACE interventional therapy is effective in increasing ORR, prolonging PFS, promoting adverse reaction endure and relieving symptoms of weakness, abdominal distension and pain.

Recent findings indicate that metastasis-associated gene in colon cancer 1 ( MACC1 ) has an abnormal high expression in most malignant tumors.As a key regulator of HGF-MET signal pathway,MACC1 could obviously up-regulate the expression of MET and promote cancer cell's movement,invasion and metastasis.Further studies will shed light on elucidating the mechanisms of metastasis and may provide a new method for targeted therapy.

Objective To study the ultrastrueture of vestibular membrane of the cochlea in guineapig. Methods The vestibular membrane in guineapig's cochlea was observed under scanning electron microscope. Results The mesothelium on the perilymphatic side was formed by a single thin layer which was intermittently discontinuous. Microvilli were few on the surface of mesothelial cells. Nuclei of the cells were large and oval in shape. A single layer of polygonal epithelial cells were observed on the endolymphatical side. The irregular polygonal epithelial cells were round and oval in shape. Many microvilli were found on this side. The junction between these cells was very tight. Conclusion The vestibular membrane is a barrier between the scala media and scala vestibule and might play a role in ion and fluid homeostasis

Objective To assess the effectiveness of the quotient of serum sodium to urinary sodium divided by (serum potassium) 2 to urinary potassium (SUSPPUP) in screening for primary aldosteronism (PA).Methods Among 952 patients with hypertension who had renin activity,aldosterone measurements and concomitant serum and urinary biochemistry data,204 patients were diagnosed as cases of PA and 261 as cases of essential hypertension.Diagnosis of PA was made in accordance with established laboratory criteria including renin activity and aldosterone,plasma aldosterone concentration/plasma renin activity (ARR),and saline loading test.The SUSPPUP ratio with the ARR were compared in two groups.Results The area under the curve of SUSPPUP and ARR was 0.797 and 0.796 respectively according to receiver operating characteristic curve,optimal cutoff of SUSPPUP was 1.0,the sensitivity and specificity of SUSPPUP was 98.9％ and 81％ respectively.Conclusions The SUSPPUP ratio is an inexpensive and rapid tool to assess the extent of mineralocorticoid excess,therefore,SUSPPUP ratio can be applied to screen PA in hypertensive patients.

Objectives To investigate the relationship between obstructive sleep apnea hypoventilation syndrome (OSAHS), insulin resistance (IR) and metabolic syndrome (MS), as well as to explore the possible mechanism of MS caused by OSAHS. Methods We recruited 186 hospitalized patients with hypertensions, who were divided into four groups based on their nocturnal polygraphs recordings, 35 as controls (group Ⅰ), 61 with mild (group Ⅱ), 52 with moderate (group Ⅲ) and 38 with severe OSAHS (group Ⅳ). They all underwent measurements including body height, body weight, waist circumference (WC), systolic and diastolic blood pressure (SBP and DBP), serum uric acid, creatinine, fasting plasma glucose, fasting plasma insulin, serum total cholesterol, high-density lipoprotein-cholesterul, low-density lipoprotein-cholesterol and triglyceride. Results One hundred and two patients with OSAHS (67.6 percent) also suffered of MS, 33 (86.8 percent) of them with severe OSAHS. There was no significant difference in age, gender, fasting plasma glucose, total cholesterol, high-density lipoprutein-cholesterul, low-density lipoprotein-cholesterol and triglyceride among the four groups (P>0.05). Body mass index (BMI), WC, ratio of serum uric acid to creatinine and DBP were all significantly higher in patients with severe OSAHS than those in patients with mild and moderate OSAHS and controls (P<0.01). SBP was significantly higher in patients with severe OSAHS than that in those with mild and moderate OSAHS (P<0.01). Insulin resistance was significantly severer in patients with severe OSAHS than that in those with mild OSAHS and controls (P<0.01). Results of multivariate linear regression analysis showed that insulin resistance was correlated with BMI and reversely correlated with minimal blood oxygen saturation, and minimal blood oxygen saturation reversely correlated with WC and ratio of uric acid to creatinine. Condusions Hypoxemia and obesity may promote development of insulin resistance. Patients of hypertension complicated with OSAHS tend to develop MS, particularly in those with severe OSAHS.

Objective To investigate the clinical efficacy of Shenqi Fuzheng injection and chemotherapy in elderly patients with non-small cell lung cancer(NSCLC),and to observe its effect on immune function and serum tumor markers of carcino embryonie antigen(CEA),carbohydrate antigen 19-9(CA19-9),cytokeratin 19 fragment(CYFRA21-1)and neuronspecific enolase(NSE).Methods 80 patients with NSCLC who were confirmed as non-small cell lung cancer were enrolled in the study.Among them,the control group received paclitaxel + carboplatin chemotherapy,40 patients; the treatment group received Shenqi Fuzheng injection on the basis of the control group,40 cases.The clinical curative effect was evaluated after four cycles of treatment and the adverse reactions were recorded.The scores of traditional Chinese medicine(TCM)syndrome before and after four cycles of treatment were evaluated,and the quality of life of the patients before and after treatment were evaluated by Karnofsky performance score(KPS).The immune function and tumor markers were measured before and after treatment.Results The total effective rate of the treatment group was 65.0％,which was significantly higher than that of the control group(42.5％,χ2=4.07,P=0.04).In the treatment group,the adverse reaction rate was 37.5％,significantly lower than 62.5％in the control group(χ2=5.00,P=0.02).The score of TCM syndrome in the two groups was significantly lower than that in the control group before treatment,and the KPS score was significantly higher than that in the control group before treatment,the score of TCM syndrome in the treatment group was significantly lower than that in the control group(P<0.05).After treatment,the immune function of patients in the treatment group compared with before treatment had no significant difference,while the control group after treatment of the immune function was significantly lower than before treatment,and compared with the treatment group(P<0.05).The two groups of patients after treatment of tumor markers decreased significantly,and the treatment group decreased significantly compared with the control group(P<0.05).Conclusion Supplemented with Shenqi Fuzheng injection in the treatment of elderly non-small cell lung cancer on the immune function of little effect,help to promote serum levels of serum tumor markers and clinical symptoms improved,reduce adverse reactions,improve clinical efficacy and quality of life.
