Objective: To estimate the burden of disease (BOD) attributable to main risk factors of chronic diseases in Zhejiang Province in 2017, so as to provide the evidence for formulating the control strategy for chronic diseases and reducing BOD. Methods: The results of the Global Burden of Disease Study 2017 ( GBD 2017 ) were extracted to evaluate years of life lost due to premature mortality ( YLL ), years lived with disability ( YLD ) and disability-adjusted life years ( DALY ). The gender- and age-specific BOD attributable to main risk factors of chronic diseases, including the environment, metabolism and behaviors, in Zhejiang Province in 2017 was estimated and compared with those in 1990. Results: High DALY rates of chronic diseases were estimated attributable to tobacco use ( 2 807.08/105 ), unreasonable diet ( 2 724.72/105 ) and hypertension ( 1 878.69/105 ) in Zhejiang Province in 2017, and high DALY rates of chronic diseases were estimated in men attributable to tobacco use ( 4 764.77/105 ), unreasonable diet ( 3 297.00/105 ) and hypertension ( 2 076.92/105 ), while high DALY rates of chronic diseases were estimated in women attributable to unreasonable diet ( 2 117.16/105 ), hypertension ( 1 668.24/105 ) and hyperglycemia ( 1 100.53/105 ), respectively. Among individuals at ages of 15 to 49 years, high DALY rates of chronic diseases were estimated attributable to unreasonable diet ( 759.29/105 ), drug abuse ( 611.71/105 ) and tobacco use ( 605.37/105 ); among individuals at ages of 50 to 69 years, high DALY rates of chronic diseases were estimated attributable to tobacco use ( 5 528.37/105 ), unreasonable diet ( 4 628.18/105 ) and hypertension ( 2 757.78/105 ); and among individuals at ages of 70 years and older, high DALY rates of chronic diseases were estimated attributable to unreasonable diet ( 16 370.09/105 ), tobacco use ( 15 551.40/105 ) and hypertension ( 14 408.63/105 ). As compared to those in 1990, the DALY rates of chronic diseases attributable to high body mass index, alcohol use, hyperglycemia, high low-density lipoprotein cholesterol and drug abuse increased by 108.23%, 48.59%, 23.17%, 17.64% and 6.06%, and the DALY rates of chronic diseases attributable to air pollution, occupational risks, unreasonable diet and impaired renal function reduced by 51.11%, 44.81%, 22.49% and 19.83%, and no significant alterations were detected in DALY rates of chronic diseases attributable to tobacco use or hypertension in 2017. Conclusions There was a high BOD of chronic diseases attributable to tobacco use, unreasonable diet and hypertension in Zhejiang Province in 2017, and the BOD of chronic diseases attributable to high body mass index, alcohol use and hyperglycemia appeared a tendency towards a rise in Zhejiang Province in 2017 relative to in 1990.

OBJECTIVE:To establish the quality standard of Jingyuan capsule. METHODS:TLC was used for qualitative iden-tification of Epimedium brevicornu,Pseudostellaria heterophylla and Fallopia multiflora in the preparation. HPLC method was used to determine the content of icariin. The determination was performed on Odyssil C18 column with mobile phase consisting of acetoni-trile-water(28:72,V/V)at the flow rate of 1.0 mL/min. The detection wavelength was set at 270 nm,and the column temperature was 30 ℃. The sample size was 10 μL. The contents of polysaccharides was determined by phenol-sulfuric method. RESULTS:TCL spots of E. brevicornu,P. heterophylla and F. multiflora were clear and well separated without interference from negative con-trol. The linear range of icariin ranged 0.027-0.135 mg/mL(r=0.9999);RSDs of precision,stability and repeatability test were all lower than 2.0%. The recoveries were 97.87%-101.94%(RSD=1.47%,n=9). The linear range of glucose ranged 0.056-0.121 mg/mL(r=0.9995),and RSDs of precision,stability and repeatability tests were all lower than 2.0%. The recoveries were 99.37%-100.38%(RSD=0.36%,n=6). CONCLUSIONS:The established standard can be used for the quality control of Jingyuan capsule.

Objective To investigate the expression and significance of epithelial cell adhesion molecule (Ep-CAM) in breast cancer.Methods Twenty-three cases of breast cancer tissue samples and paired lymph node metastases confirmed pathologically were collected.Isobaric tags for relative and absolute quantitation (iTRAQ) proteomics technology was used to screen and identify the differentially expressed proteins between primary tumor and lymph node metastasis of breast cancer.The expression of Ep-CAM was detected by Western blotting in 4 cases of primary breast cancer tissues and paired lymph node metastases.And the expressions of Ep-CAM in 252 cases of breast lesions were detected by immunohistochemical method.Results Quantitative proteomic examination results showed that differentially expressed proteins existed in breast cancer primary tumor and lymph node metastasis,and the expression of Ep-CAM in metastatic lesions was higher than that in primary tumor.Western blotting results showed that the expression of Ep-CAM in metastatic lesions (1.46 ± 0.22) was higher than that in primary tumor (1.16 ± 0.09),which was consistent with the results of proteomic.The immunohistochemical results showed that the positive expression rate of Ep-CAM in lymph node metastasis tissues (93.16％,109/117) was significantly higher than that in primary breast cancer without metastasis (72.73％,64/88),and the difference was statistically significant (x2 =15.921,P =0.000).The positive expression rate of Ep-CAM in primary breast cancer with lymphatic metastasis (72.65％,85/117) was lower than that in paired lymph node metastases (P =0.001).Conclusion Ep-CAM is differentially expressed in primary tumor and lymph node metastasis of breast cancer,which may be related to the lymphatic metastasis of breast cancer.

A sandwich format immunochromatographic assay for detecting foot-and-mouth disease virus (FMDV) serotypes was developed. In this rapid test, affinity purified polyclonal antibodies from Guinea pigs which were immunized with sucking-mouse adapted FMD virus (A/AV88(L) strain) were conjugated to colloidal gold beads and used as the capture antibody, and affinity purified polyclonal antibodies from rabbits which were immunized with cell-culture adapted FMD virus (A/CHA/09 strain) were used as detector antibody. On the nitrocellulose membrane of the immunochromatographic strip, the capture antibody was laid on a sample pad, the detector antibody was printed at the test line(T) and goat anti-guinea pigs IgG antibodies were immobilized to the control line(C). The lower detection limit of the test for a FMDV 146S antigen is 11.7ng/ml as determined in serial tests after the strip device was assembled and the assay condition optimization. No cross reactions were found with FMDV serotype C, Swine vesicular disease (SVD), Vesicular stomatiti svirus (VSV) and vesicular exanthema of swine virus (VES) viral antigens with this rapid test. Clinically, the diagnostic sensitivity of this test for FMDV serotypes A was 88.7% which is as same as an indirect-sandwich ELISA. The specificity of this strip test was 98.2% and is comparable to the 98.7% obtained with indirect-sandwich ELISA. This rapid strip test is simple, easy and fast for clinical testing on field sites;no special instruments and skills are required, and the result can be obtained within 15 min. To our knowledge, this is the first rapid immunochromatogarpic assay for serotype A of FMDV.

Objective To analyze CT findings of insulinoma,and to summarize the causes of missed diagnosis of nontypical insuli-noma.Methods Clinical and CT manifestations of 18 patients with 18 insulinomas were analyzed retrospectively which were proved by surgery and pathology,and the causes of the missed diagnosis of nontypical insulinoma were also summarized.Results 10 patients with 10 insulinoma underwent CT plain scan with isodensity in 9 and slightly lower density in 1 with thread-like capsule.Other 18 patients underwent enhanced CT scan,10 of whom showed obvious enhancement in arterial phase with isodentisy in 6 and slightly higher density in 4 in portal phase,and isodensity in 10 in delayed phase.4 lesions showed mild-to-moderate enhancement in arterial phase with slightly higher density than normal pancreas in 2 and isodentisy in 2 in portal phase,and slightly higher density than nor-mal pancreas in 1 and similar density to pancreas in 3 in delayed phase.In portal phase,the enhanced degree in 8 was similar to the pancreas,and that in 6 was slightly higher or higher than that of pancreas.In delayed phase,13 were similar to the pancreas and other 1 was higher than that.3 of 18 lesions were easily missed,and 4 lesions with missed diagnosis showed isodensity on plain CT and en-hanced CT,and were further detected by other imaging methods.Conclusion Multiphase enhancement CT scanning can be used as the first choice for the insulinoma.

Objective To explore inhibition of nicotine on apoptosis of chondrocytes induced by monosodium iodoacetate ( MIA) .Methods Rat primary chondrocytes were isolated by enzyme digestion, and the cells were treated with 10 -8 , 10 -7 , 10 -6 , 10 -5 mol/L nicotine for 48 h.The cases were randomly divided into five groups, except for normal group, the other four groups were treated with 4μmol/L MIA 24 h, and three groups were treated 10 -8 , 10 -7 , 10 -6 mol/L nicotine.The viability of chondrocytes was detected by MTT assay.The apoptosis of chondrocytes was examed by Annexin V-FITC/PI flow dual-staining method.The activity of cysteinyl aspartate specific proteinase 3 ( Caspase 3 ) was measured by spectrophotography method.The activation of phosphatidylinositol 3 kinase ( PI3K)/protein kinase B ( AKT) and the expression of down-stream molecule Bax, Bcl-2 was assayed by western blot.Results 10 -7 , 10 -6 mol/L nicotine increased chondrocytes' viability (P<0.05), 10 -5mol/L nicotine reduced chondrocytes' viability (P<0.05), and 10 -8 mol/L nicotine didn't effect on chondrocytes' viability (P>0.05).10 -8, 10 -7, 10 -6 mol/L nicotine could increase MIA-induced chondrocytes' viability (P<0.05), suppress MIA-induced chondrocytes' apoptosis and the activity of MIA-induced Caspase 3 (P <0.05).Moreover, 10 -7, 10 -6 mol/L nicotine could increase the expression of PI3K and phosphorylation of AKT ( P<0.05) , down-regulate the expression of Bax and up-regulate the expression of Bcl-2 in MIA-induced rat chondrocytes ( P<0.05 ) .Conclusion These results suggested nicotine could exert anti-apoptosis in MIA-induced rat chondrocytes, which might be related to PI3K/AKT signal pathway.

Objective To evaluate the effect of positive end-expiratory pressure (PEEP) on intraoperative pulmonary function in the patients undergoing urological retroperitoneal laparoscopic surgery in the mode of protective ventilation.Methods Forty patients of both sexes,aged 30-64 yr,with body mass index of 16-29 kg/m2,of American Society of Anesthesiologists physical status Ⅰ or Ⅱ,scheduled for elective retroperitoneal laparoscopic ureterolithotorny,were randomly divided into 2 groups (n =20 each) using a random number table:control group (group C) and PEEP group (group P).After induction of general anesthesia,the patients were endotracheally intubated.Intermittent positive pressure ventilation (tidal volume [Vr] 6 ml/kg,respiratory rate [RR] 12 breaths/min,inspiratory/expiratory ratio [I:E] 1:2,fraction of inspired oxygen 50％) was performed from the end of intubation until the onset of pneumoperitoneum.After the onset of pneumoperitoneum,the patients were ventilated (VT 6 ml/kg,RR 22 breaths/min,I:E 1.0:1.5),and the end-tidal pressure of carbon dioxide was maintained at 35-45 mmHg in group C.After the onset of pneumoperitoneum,the patients were ventilated (VT 6 ml/kg,RR 22 breaths/min,I:E1.0:1.5,PEEP 5 cmH2O),and the end-tidal pressure of carbon dioxide was maintained at 35-45 mmHg in group P.At 5 min before pneumoperitoneum (T1),at 10,30 and 60 min of pneumoperitoneum (T2-4),immediately after the end of pneumoperitoneum (T5),and at 5 min before extubation (T6),arterial blood samples were collected for blood gas analysis.Peak airway pressure and mean airway pressure were also recorded.Dynamic lung compliance,oxygenation index,respiratory index,dead space fraction and alveolararterial oxygen gradient were calculated.Results Compared with group C,mean airway pressure was significantly higher at T2-4,oxygenation index was significantly higher at T3,alveolar-arterial oxygen gradient difference was significantly lower at T3 and T6,and respiratory index was significantly lower at T6 (P＜0.05),and no significant change was found in the peak airway pressure,dynamic lung compliance and dead space fraction at each time point in group P (P＞0.05).Conclusion PEEP (5 cmH2O) can improve the intraoperative pulmonary function in the patients undergoing urological retroperitoneal laparoscopic surgery in the mode of protective ventilation.

Objective: To investigate the degree and influencing factors of glycosylated hemoglobin ( HbA1c ) control among patients with type 2 diabetes ( T2DM ) living in rural communities of Zhejiang Province, so as to provide the reference for optimizing the management of diabetes patients in rural communities. Methods: Permanent adult patients with T2DM that were registered and received standardized management in all communities of Jiashan County and Suichang County, and 6 communities of Yongkang City, Zhejiang Province in 2016 were recruited, and their demographic characteristics were captured from the health record system and chronic disease management system. The height, body weight, waist circumstance and blood pressure were measured, and HbA1c and blood lipid parameters were detected. The degree of HbA1c control ( <7% ) was analyzed, and its influencing factors were identified using a multivariable logistic regression model. Results: A total of 10 339 patients with T2DM were enrolled, including 4 520 men ( 43.72% ) and 5 819 women ( 56.28% ), with a mean age of ( 63.54±9.78 ) years and the mean course of diabetes of ( 6.36±4.73 ) years. The rate of HbA1c control was 47.89%. Multivariable logistic regression analysis showed that males ( OR=1.123, 95%CI: 1.024-1.233 ), region ( Suichang, OR=2.413, 95%CI: 2.106-2.765; Yongkang, OR=2.460, 95%CI: 2.188-2.767 ), course of disease ( 5-9 years, OR=1.724, 95%CI: 1.504-1.977; 10 years and longer, OR=2.881, 95%CI: 2.477-3.351 ), use of hypoglycemic drugs ( OR=1.203, 95%CI: 1.089-1.329 ), development of chronic complications ( OR=1.190, 95%CI: 1.027-1.379 ), uncontrolled blood pressure ( OR=1.140, 95%CI: 1.030-1.261 ), uncontrolled blood lipid ( OR=1.258, 95%CI: 1.104-1.433 ), and smoking ( OR=1.318, 95%CI: 1.165-1.491 ) were statistically associated with HbA1c control among T2DM patients. Conclusion The rate of HbA1c control was 47.89% among T2DM patients in rural communities of Zhejiang Province. HbA1c control should be given a high priority among men living in low-economic-level regions with long course of disease, use of hypoglycemic drugs, chronic complications, smoking, uncontrolled blood pressure and lipid.
