OBJECTIVESTo investigate the influencing factors of nonalcoholic fatty liver disease (NAFLD).

METHODSA hospital-based case-control study was conducted in patients with NAFLD and controls without NAFLD in a hospital from January to August in 2007. All data were analyzed by SPSS 13.0 software.

RESULTSOne-way analysis of variance found that the two groups were significantly different in cigarette smoking, alcohol and tea comsumption, movement index, speed of food intake, frequency of social engagement, kinds of edible oil, marine products, family history of NAFLD, hypertension, higher blood sugar, abnormality of blood fat, higher level of ALT, higher level of AST, hyperuricemia, obesity, decrease of high density lipoprotein (HDL), and increase of low density lipoprotein. By non-conditional logistic stepwise regression analysis, 12 of 18 factors were used to construct a model, ten of which were the risk factors and two were protective factors of NAFLD. Risk factors included obesity (OR=6.35), hypertension(OR=3.82), dyslipidemia (OR=2.95), decrease of HDL (OR=2.85), hyperglycemia (OR=2.82), increase of ALT (OR=2.80), hyperuricemia (OR=2.35), HBsAg positive (OR=1.99), family history of fatty liver (OR=1.79) and frequently intake of marine products (OR=1.58), and protective factors included tea drinking (OR=0.72) and exercise (OR=0.90).

CONCLUSIONSThere are many influencing factors of NAFLD, and life styles are the key factors. Genetic background may also play some roles in NAFLD.

OBJECTIVETo explore the relationship between body mass index, waist circumference and blood pressure among residents in Chongqing area.

METHODSA total of 5246 residents aged 15 and over in Chongqing area were enrolled in this study by use of stratified sampling and cluster sampling methods. Data on blood pressure (SBP, DBP), pulse, height, body weight, waist and hip circumferences as well as questionnaire survey were analyzed.

RESULTSThe level of SBP and DBP and hypertension prevalence rate were significantly positively correlated with BMI (all P < 0.01). SBP, DBP levels and hypertension prevalence rate were significantly higher in people with abdomen obesity than people with normal waist circumference (all P < 0.01). BMI, waist circumference in hypertensive residents were significantly higher than non-hypertensive residents (all P < 0.01).

CONCLUSIONBlood pressure level and hypertension prevalence rate were closely related with BMI and waist circumference among residents in Chongqing area.

OBJECTIVETo prepare (99m)Tc-labeled Anti-VEGF mAb 5-FU loaded polylactic acid nanoparticles ((99m)Tc-Ab-5-FU-NPs) and investigate its biodistribution in human gastric carcinoma xenografts.

METHODS(99m)Tc-Ab-5-FU-NPs were prepared by labeling Ab-5-FU-NPs with (99m)Tc using improved Schwarz method. After isolation of (99m)Tc-Ab-5-FU-NPs using SephadexG250 column, the labeling ratio and radiochemical purity were determined using chromatography. The immunocompetence of (99m)Tc- Ab-5-FU-NPs was detected by ELISA and immunohistochemistry. (99m)Tc-Ab-5-FU-NPs were then injected via the tail vein into SCID mice bearing human gastric carcinoma, and (99m)Tc labeled mice-derived monoclonal IgG loaded polylactic acid nanoparticles were used as the control, followed by radioimmunoscintigraphic imaging at 2 and 6 h. The radioactive count and radioactive ratio of the tumor and non-tumor tissue (T/NT) in the animal models were calculated using ROI technique. After imaging at 24 h, SCID mice were sacrificed and the radioactive distribution, the %ID/g, as well as the T/NT radioactive ratio were examined, respectively. The concentrations of 5-FU in the tumor and blood were also detected using HPLC method.

RESULTSThe labeling ratio of (99m)Tc-Ab-5-FU-NPs was 90%-95%. (99m)Tc-Ab-5-FU-NPs were detected in the tumor tissues by radioimmunoimaging 2 h after the injection. ID%/g in the tumor tissues at 2 and 6 h were both significantly higher than that of the control group. Both the ID%/g in tumor tissues and radioactive ratio of tumor and blood at 6 h were higher than those at 2 h, and the concentration of 5-FU in experimental group increased continuously with time and was significantly higher than that in control group.

CONCLUSIONS(99m)Tc-Ab-5-FU-NPs prepared in this study can meet the demands of radioimmunoimaging, and the anti-VEGF monoclonal antibody possesses reliable immune targeting ability. Six hours after injection, (99m)Tc-Ab-5-FU-NPs can specifically accumulate in the tumor tissues in human gastric carcinoma xenografts at high concentration.

OBJECTIVETo compare the clinicopathological characteristics and prognosis of patients with small (≤5 cm) solid pseudopapillary neoplasm of the pancreas (SPN) and those with large (>5 cm) SPNs.

METHODSWe retrospectively analyzed the clinical characteristics, laboratory findings, radiological features, treatment and prognosis of 148 patients with histologically confirmed SPN between August, 2006 and December, 2014 and compared the data between patients with small SPNs (≤5 cm) and those with large SPNs (>5 cm).

RESULTSIn the large SPN group, the female-to-male ratio was significantly higher than that in small SPN group (61/8 vs 56/23, P=0.009) and the patients were significantly younger in large SPN group (28.3±12.3 vs 33.0±11.4 years, P=0.016). Small SPNs (≤5 cm) typically presented as inhomogeneous solid or cystic tumors, while large SPNs (>5 cm) often appeared as homogeneous solid and cystic tumors, but they did not show any significant difference in aggressive behaviors (P=0.288). The 5-year disease-free survival of patients with small SPNs was 100%, and the 1-, 3-, and 5-year disease-free survival of patients with large SPNs was 98.6%, 94.9%, and 89.3%, respectively (P=0.030), showing no significant differences in the overall survival between the two groups.

CONCLUSIONSmall SPNs and large SPNs have different clinical characteristics. Even with complete resection, tumors larger than 5 cm are more likely to have tumor recurrence and metastasis, and close follow-up is recommended for these patients.

OBJECTIVETo investigate the therapeutic effect of acupoint injection of bee venom on collagen-induced arthritis (CIA) in rats and explore the mechanism of bee venom therapy in the treatment of rheumatoid arthritis.

METHODSFifteen male Wistar rats were randomly divided into bee venom treatment group (BV group), CIA model group, and control group. In the former two groups, CIA was induced by injections of collagen II+IFA (0.2 mL) via the tail vein, and in the control group, normal saline was injected instead. The rats in BV group received daily injection of 0.1 mL (3 mg/mL) bee venom for 7 consecutive days. All the rats were assessed for paw thickness and arthritis index from days 14 to 21, and the pain threshold was determined on day 21. The expressions of TRPV1 and TrkA in the dorsal root ganglion at the level of L4-6 were detected using immunohistochemistry and Western blotting, respectively.

RESULTSThe rats in CIA model group started to show paw swelling on day 10, and by day 14, all the rats in this group showed typical signs of CIA. In BV group, the rats receiving been venom therapy for 7 days showed a significantly smaller paw thickness and a low arthritis index than those in the model group. The pain threshold was the highest in the control group and the lowest in the model group. TRPV1-positive cells and TrkA expression in the dorsal root ganglion was significantly reduced in BV group as compared with that in the model group.

CONCLUSIONs Injection of bee venom can decrease expression of TRPV1 and TrkA in the dorsal root ganglion to produce anti-inflammatory and analgesic effects, suggesting the potential value of bee venom in the treatment of rheumatoid arthritis.

OBJECTIVETo explore the risk factors of acute lymphoblastic leukemia (ALL) recurrence in adult patients and establish a prognosis index (PI) calculation model in order to improve the prevention strategy of ALL in adults.

METHODS104 adult ALL patients from Blood Diseases Hospital & Chinese Academy of Medical Sciences between August 2008 and November 2011 were enrolled. COX proportional hazards regression stratified by Dummy variable was used to set up the prediction model; Kaplan-Meier method and Log-rank test were used to estimate and compare the survival. After calculated individual PI value, patients' expected survival should be estimated by groups.

RESULTSThe overall median survival of adult ALL patients was 22.00 months (95% CI 17.00-27.00). COX regression analysis showed that chemotherapy group patients had a higher risk of recurrence than of ASCT group while setting treatment as the dummy variable (RR=2.052, 95%CI 0.877-4.799, P=0.007). Stratified Analysis showed that the risk factors of B-ALL recurrence in adult patients included HGB <100 g/L (RR=0.186, 95% CI 0.068-0.512, P=0.001), CNSL (RR=7.767,95% CI 2.951- 20.433, P=0.001), number of consolidation chemotherapy<3 (RR=0.445, 95% CI 0.211-0.940, P=0.034) and Ph chromosome positive (RR=2.771, 95% CI 1.353-5.674, P=0.005). Grouped by the PI value, the expected survival of each individual patient could be estimated as PI=0.58 base.

CONCLUSIONHGB, CNSL, number of consolidation chemotherapy and Ph chromosome were independent risk factors of B-ALL recurrence in adult patients. PI value could predict the survival of adult ALL patients and provide reference for individual therapy and prognostic evaluation.

Based on standard carotid endarterectomy, we performed modified carotid endarterectomy in two cases of carotid artery stenosis by changing the direction of the carotid artery incision to avoid restenosis of the internal carotid artery without using a patch. The two patients recovered smoothly without any complications. Compared with eversion or patch endarterectomy, this modified carotid endarterectomy avoids restenosis of the carotid artery and shortens operation time.

OBJECTIVETo detect the frequencies of anti-GPIIb/IIIa antibody secreting B cells and platelet-specific antibody in patients with idiopathic thrombocytopenic purpura (ITP) and non-immune thrombocytopenia, and to evaluate their roles in the diagnosis of ITP and their clinical significance.

METHODSThe frequencies of circulating B cells secreting anti-GPIIb/IIIa antibody and platelet-specific antibody in 58 ITP patients, 33 non-ITP patients and 31 healthy controls were tested by Enzyme-linked Immunospot Assay (ELISPOT) and modified monoclonal antibody immobilization of platelet antigens assay (MAIPA) respectively.

RESULTSThe frequencies of circulating B cells secreting anti-GPIIb/IIIa antibody in ITP patients \[(6.6 ± 4.2)/10(5) PBMNC\] were significantly increased (P < 0.05) than that of the controls \[(1.3 ± 0.5)/10(5) PBMNC\] and non-immune thrombocytopenic purpura patients \[(2.2 ± 2.0)/10(5) PBMNC\]. However there was no apparent difference between the latter two groups (P > 0.05). ELISPOT had a sensitivity of 70.69%, a specificity of 90.91% for the diagnosis of ITP, the sensitivity being higher than that of modified MAIPA's (43.10%) (χ(2) = 7.03, P < 0.05). The ROC curve showed the discriminative validity of cytometric bead array was 0.886.

CONCLUSIONThe frequencies of circulating B cells secreting anti-GPIIb/IIIa antibody may reflect the pathogenesis of ITP. ELISPOT assay have high sensitivity and specificity than modified MAIPA for the diagnosis of ITP and the guidance for clinical therapy.
