Objective To investigate the expression of serum tumor markers in pancreatic carcinoma and to assess the value of serum tumor markers in the diagnosis and prognosis of pancreatic carcinoma. Methods Five serum tumor markers including AFP, CEA, CA199, CA125 and CA242 were detected in 95 patients with pancreatic carcinoma by chemi-luminescence immunoassay (CLI) and enzyme linked immunosorbent assay (ELISA), 80 patients with other malignant tumor and 65 patients with benign disease served as controls. Five tumor markers in pancreatic carcinoma diagnosis for TNM staging were compared. The value of tumor markers for prognosis was analyzed. Results Among these 5 kinds of tumor marker, CA199, CAI25, CA242 were valuable in diagnosis of pancreatic carcinoma, and CA199 was the most valuable one, whose sensitivity and specificity were 76.2 % and 74.8 % respectively. CA199, CA125, CA242 were increased with progression of pancreatic carcinoma. Conclusion Serum CA199, CA125 and CA242 are the preferred tumor markers to be used in the diagnosis and prognosis of pancreatic carcinoma.

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.

Objective To assess the proficiency of water monitoring laboratory at rural, county, and provincial levels in Guangdong province, to ensure the province's drinking water monitoring results accurate and reliable. Methods State quality of certified reference materials as water arsenic, fluoride and chloride of 90 copies each were numbered and distributed to 90 monitoring laboratories in the province for testing, The measurement results of the participatory labs were evaluated through normative values and expanded uncertainty, and were compared with those of robust statistics method. Results All participatory labs had timely feedback of their measurement results. The qualified rate was higher when arsenic was tested by hydride generation atomic fluorescence spectrometry and zinc-new silver salt of sulfuric acid spectrophotometric system, while fluoride and chloride by ion chromatography. The average qualified rates of water arsenic, fluoride and chloride of the province's rural drinking water quality monitoring laboratory were 66% (59/90), 72% (65/90) and 72% (65/90), respectively.Seven participatory labs failed the proficiency testing of all three analytes and unqualified rate was 7.8% (7/90)among the ninety participated monitoring labs. The qualified rates of robust statistics method for arsenic fluoride and chloride were greater than those evaluated by the expanded uncertainty, and large deviations with small sample sizes. Conclusions The testing ability of drink-water monitoring labs in Guangdong province has improved.However, by comparison with the requirements of national quality control and testing skills, there is still a gap. It is suggested that internal quality control be included in routine inspeetion to improve laboratory testing technology.

OBJECTIVETo observe the expression profiles of osteoblast-related genes in human mesenchymal stem cells (MSCs) derived from bone marrow during osteogenic differentiation.
METHODSMSCs were induced to differentiate with MSC osteogenic differentiation medium for 7, 14, 21 and 28 days respectively. Alizarin Red staining was used to detect matrix mineralization. Expression of osteoblast-related genes, including osteocalcin, osteopontin, Runt-related transcription factor 2 (Runx2), alkaline phosphatase and collagen type 1, was assessed with quantitative reverse transcription-polymerase chain reaction.
RESULTSOn day 14 after induction of differentiation, cells were stained positively with Alizarin Red. The expression levels of these genes exhibited an upward trend as induction time was prolonged. Exposure to osteogenic differentiation medium less than 21 days did not significantly induce osteocalcin expression; osteocalcin expression levels in the differentiated cells induced for 21 and 28 days were 1.63 and 2.46 times as high as the undifferentiated cells respectively (all P<0.05). Stimulation with MSC osteogenic differentiation medium over 14 days significantly enhanced bone marrow-derived MSCs to express osteopontin and Runx2 genes (all P<0.05). Osteogenic differentiation medium could significantly induce the expressions of alkaline phosphatase and collagen type1 genes (all P<0.05). Their expressions reached the peak levels on day 21, which were increased more than 4- and 3-fold respectively.
CONCLUSIONHuman bone marrow-derived MSCs could exhibit the sequential expression pattern of osteoblast marker genes during osteogenic differentiation in vitro.
