OBJECTIVETo explore the efficacy and effect mechanism of the combined therapy of acupuncture and tapping method in the treatment of obesity and hyperlipidemia of liver qi stagnation and spleen deficiency pattern in the patients.

METHODSOne hundred and four female patients were randomized into a combined therapy of acupuncture and tapping (combined therapy group) group method and an acupuncture group, 52 cases in each group. In the acupuncture group, acupuncture was applied to Qimen (LR 14), Taichong (LR 3), Zhangmen (LR 13), Taibai (SP 3), Zusanli (ST 36), Geshu (BL 17), Ganshu (BL 18), Pishu (BL 20), etc. In the combined therapy group, on the basis of acupuncture treatment, the tapping method with plum blossom needle was used at each acupoint. The treatment was given once every two days, continuously for 3 months in the two groups. The indices were observed, including the obesity indices, such as body mass, body mass index (BMI), body fat percentage (F%) and obesity degree (A); the blood lipid levels such as total cholesterol (TC), triglyceride (TG), low density lipoprotein (LDL) and high density lipoprotein (HDL); the fat-islet axie relevant indices such as fasting plasma glucose (FBS), fasting leptin (FLP), fasting insulin (FINS), insulin sensitive index (ISI), insulin resistance in- dex (Homa IR), insulin secretion index (Homa-β) and autonomic nerve function index (Y value) before and after treatment in the patients of two groups. The efficacy was compared between the two groups.

RESULTSThe total effective rates were 96.2% (50/52) and 84.6% (44/52) in the combined therapy group and the acupuncture group respectively, without significant difference in comparison (P > 0.05). Obesity indices, blood lipid indices, fat-islet axie relevant indices and autonomic nerve function indices were all improved after treatment as compared with those before treatment in the two groups (P < 0.01, P < 0.05), and the improvements in the combined therapy group were much more significant (P < 0.01, P < 0.05).

CONCLUSIONThe combined therapy of acupuncture and tapping method achieves the double effects of weight loss and lipid loss in the treatment of obesity combined with hyperlipidemia. The effect mechanism is possibly related to the positive regulations of blood glucose, lipid metabolism and fat-islet axie in the patients.

AIM: To determine tissue distribution of rat ?-defensin rBD-1 gene expression.METHODS: Total RNA was isolated from 10 kinds of rat tissues. RT-PCR were performed with primers (R 1 5′→3′ ACTCTGGACCCTGACTTCACCG; R 2 5′→3′ CCCTTGCTTGTCCTTTATGTCC). The RT-PCR products around 272 bp in size were cloned into pGEM-T easy vector and the recombinant clones were analyzed by digestion with restriction endonucleases and DNA sequencing.RESULTS: Rat ?-defensin rBD-1 transcripts were found in the kidney and skin, whereas its mRNA was not detected in trachea, uterus, bladder, small intestine, spleen, skeletal muscle, bone marrow and parotid. Sequence analysis confirmed that the RT-PCR product is rBD-1 cDNA. CONCLUSION: These data suggested that ?-defensin rBD-1 may participate not only in the kidney but also in the skin natural defense against infections.

Aim To investigate the effects of silencing MALAT1 gene on cell proliferation inhibition and apop-tosis induced by Melittin in human hepatocellular car-cinoma HepG2 cells. Methods The inhibitory rate of cell proliferation treated with Melittin in HepG2 cells was examined by MTT assay. Apoptotic rate was detec-ted by flow cytometry. The MALAT1 expression level in HepG2 cells was measured by qPCR. Specific siR-NAs were utilized to silence MALAT1 expression. The rates of cell proliferation inhibition and apoptosis in HepG2 cells treated with siRNA and Melittin were compared with those of Melittin alone. Results Melit-tin significantly suppressed the growth of HepG2 and induced cell apoptosis in a dose-dependent manner. Compared with normal liver cell lines, MALAT1 was highly expressed in HepG2 cells ( P<0. 05 ) . The ex-pression of MALAT1 in HepG2 cells was inhibited by Melittin, and the inhibitory rate increased with the in-crease of concentration. The rates of cell proliferation inhibition and apoptosis in HepG2 cells treated with siRNA and Melittin were significantly higher than those treated merely with Melittin. Conclusion Melittin can reduce the expression of MALAT1 and silencing MALAT1 can effectively promote proliferation inhibi-tion and apoptosis in HepG2 cells induced by Melittin.

Objective By using multi detector row spiral CT (MDCT) to investigate the CT imaging findings of gallbladder abnormalities caused by hepatic parenchymal diseases and those of inflammatory cholecystitis. Methods CT and clinical data of 80 patients with gallbladder abnormalities were retrospectively reviewed. Fifty patients were in hepatic disease group, including 20 chronic hepatitis, 25 liver cirrhosis, and 5 cirrhosis with hepatocellular carcinoma. Thirty patients were in inflammatory group, including 19 chronic cholecystitis, 6 acute cholecystitis, 3 cholecystitis with acute pancreatitis, 1 gangrenous cholecystitis, and 1 xanthogranulomatous cholecystitis. All patients underwent MDCT plain scan and contrast enhanced dual phase scanning of upper abdomen. Results In hepatic disease group, 48 cases had evenly thickened gallbladder wall (96%) with mean thickness of (3.67?0.49) mm; 38 cases had clear gallbladder outlines (76%); 38 cases had gallbladder wall enhancement of various degree (76%); 14 cases had gallbladder bed edema and localized non dependant pericholecystic fluid collection (28%). In inflammatory cholecystitis group, 28 cases had obscuring gallbladder outlines (93%) ; 26 cases had gallbladder wall evenly thickened (87%), 4 cases showed unevenly thicked wall (13%), the mean thickness being (4.54?1.14) mm; 30 cases had inhomogenous enhancement of the gallbladder wall (100%); 9 cases had high attenuation bile (30%); 4 cases had dependant pericholecystic fluid collection (13%); 5 cases had transient enhancement of adjacent hepatic bed in arterial phase (17%); micro abscess and gas in the gallbladder wall was observed in 1 case respectively. Conclusion MDCT can offer imaging findings useful for differentiating abnormal gallbladder changes caused by hepatic parenchymal diseases from those due to inflammatory cholecystitis.
