Abstract
PURPOSE To study MRI findings of hemorrhage in acute pancreatitis (AP) and correlate the presence and extent of hemorrhage with the MR severity index (MRSI), Acute Physiology And Chronic Health Evaluation (APACHE) II scores, and clinical outcome. MATERIALS AND METHODS This retrospective study included 539 patients with AP. Hemorrhage was defined as areas of hyperintensity in or outside the pancreas on liver imaging with volume acceleration flexible (LAVA-Flex). The presence of hemorrhage was classified into three areas: within the pancreatic parenchyma, retroperitoneal space, and sub-or intraperitoneal space. Involvement of each area was awarded 1 point resulting in the hemorrhage severity index (HSI) score. The predicted severity of AP was graded by MRSI and APACHE II score. The association between HSI, MRSI, and APACHE II scores was analyzed. The length of hospital stay and organ dysfunction was used as clinical outcome parameters. RESULTS Among 539 AP patients, 62 (11.5%) had hemorrhage. The prevalence of hemorrhage was 1.1% (2/186), 13.9% (43/310), and 39.5% (17/43) in predicted mild, moderate, and severe AP, respectively, based on MRSI (χ2 = 55.3, p = 0.00); and 7.7% (21/273) and 19.2% (18/94) in predicted mild and severe AP, respectively, based on APACHE II (χ2 = 21.2, p = 0.00). HSI score significantly correlated with MRSI (r = 0.36, p < 0.001) and APACHE II scores (r = 0.21, p = 0.00). The prevalence of organ dysfunction was higher and length of hospital stay was longer in patients with hemorrhage than in those without hemorrhage (p < 0.01). CONCLUSIONS Hemorrhage in AP is common. The presence of hemorrhage, rather than its extent, correlates with poor clinical outcome.

Abstract
Objective: To analyze the resting energy expenditure and optimal energy supply in different age groups of critically ill children on mechanical ventilation in pediatric intensive care unit (PICU). Methods: Patients on mechanical ventilation hospitalized in PICU of Beijing Children's Hospital from March 2015 to March 2016 were enrolled prospectively. Resting energy expenditure of patients was calculated by US Med Graphic company critical care management (CCM) energy metabolism test system after mechanical ventilation. Patients were divided into three groups:<3 years, 3-10 years, and >10 years. The relationship between the measured and predictive resting energy expenditure was analyzed with correlation analysis; while the metabolism status and the optimal energy supply in different age groups were analyzed with chi square test and variance analysis. Results: A total of 102 patients were enrolled, the measured resting energy expenditure all correlated with predictive resting energy expenditure in different age groups (<3 years (r=0.3, P=0.0) ; 3~10 years (r=0.6, P=0.0) ;>10 years (r=0.5, P=0.0) ) . A total of 40 cases in < 3 years group, including: 14 cases of low metabolism (35%), 14 cases of normal metabolism (35%), and 12 cases of high metabolism (30%); 45 cases in 3-10 years group, including: 22 cases of low metabolism (49%), 19 cases of normal metabolism (42%), 4 cases of high metabolism (9%); 17 cases in>10 years group, including: 12 cases of low metabolism (71%), 4 cases of normal metabolism (23%), 1 case of high metabolism (6%). Metabolism status showed significant differences between different age groups (χ(2)=11.30, P<0.01, r=-0.01). Infants had higher metabolic status, which lessened with aging. The total average actual energy requirement was (210±84) kJ/ (kg⋅d) . There were significant differences in actual energy requirement between age groups (F=46.57, P<0.001), with (277±77) kJ/ (kg⋅d) in<3 years group, (184±53) kJ/ (kg⋅d) in 3-10 years group, and (120±30) kJ/ (kg⋅d) in>10 years group. Conclusion: The resting energy metabolism of the critically ill children on mechanical ventilation is negatively related to the age. The actual energy requirement should be calculated according to different ages.

Abstract
Recent studies have shown that liver dysfunction is an early event in sepsis. Pre-existing liver dysfunction is a risk factor for progression of infection to sepsis. However, the mechanism of the liver immune response in promoting sepsis and the importance of liver function are not completely understood. In the present study, we investigated the protective effect of erythropoietin (EPO) against mitochondrial dysfunction in a lipopolysaccharide (LPS)-induced sepsis model, and examined the underlying signaling mechanisms. Enzyme linked immunosorbent assay (ELISA) and reactive oxygen species (ROS) analysis were used to evaluate the levels of interleukin (IL)-1β and ROS. The effects of EPO on hepatic mitochondrial function were studied by detecting the mitochondrial DNA (mtDNA) copy number using real-time PCR (RT-PCR). To explore the mechanism of action of EPO in sepsis, protein expressions of IL-1β, caspase-1 and NLRP3 were assessed by Western blotting; liver histopathology and ultrastructure of liver mitochondria was examined by transmission electron microscopy. We found that LPS treatment increased serum IL-1β and ROS levels, the effect of which was attenuated by EPO. Moreover, LPS treatment also increased the mtDNA copy number and the protein expressions of IL-11β, caspase-1, and NLRP3, which were suppressed by EPO. Histological examination of liver showed LPS-induced cellular edema in hepatic lobules, lymphocytic infiltration and hepatocellular necrosis; these changes were also alleviated by EPO treatment. On electron microscopy, the size of hepatocellular mitochondria in the LPS group was smaller than that in the control group, and the changes were reversed by EPO in the LPS+EPO group. Our results suggest that EPO alleviated liver and mitochondrial damage induced by LPS, possibly via inhibition of NLRP3 signaling.

Abstract
Grape white rot is a common disease and causes considerable yield losses in many grape-growing regions when environmental conditions are favorable. We surveyed grape white rot in five provinces in China and collected 27 isolates from diseased grape tissues. Multigene phylogenetic analyses of the internal transcribed spacer region (ITS1-5.8S-ITS2), the 28S large subunit of nuclear ribosomal RNA (LSU), partial translation elongation factor 1-alpha gene (TEF 1-α), and partial histone 3 gene (HIS), coupled with genealogical concordance phylogenetic species recognition and morphological observations, revealed that Coniella vitis sp. nov. and C. diplodiella are the causal agents of grape white rot in China. Koch's postulates were performed on Vitis vinifera cv. Summer Black in a greenhouse. These results confirmed the pathogenicity on grapes, as symptoms were reproduced, and also indicated significant variations in the virulence among C. vitis isolates. This work provides evidence that C. vitis is the main pathogen of grape white rot in China and also provides an optimized multigene backbone for resolving Coniella species.

Abstract
Objective: To estimate the early physical growth and disease in children born to HBsAg-positive mothers. Methods: This was a retrospective cohort study. Three areas as Xihu in Hangzhou, Lanxi in Jinhua, and Haiyan in Jiaxing in Zhejiang province were selected by cluster sampling. The growth outcomes of children born to HBsAg-positive mothers (exposure group) and matched 1∶1 women uninfected with HBV (control group) in 2014 were investigated and compared at birth, 6, 9, 12, and 18 months, respectively. There were totally 342 children in each group. Results: The incidences of low birth weight (LBW) for children born to exposure and control group were 1.8% (6/342), and 2.6% (9/342), respectively (P=0.433); and, rates of preterm birth were 2.3% (8/342), and 2.0% (7/342), respectively (P=0.794). The mean birth weight of children born to mothers without HBV infection (3.4±0.4) kg was dramatically higher than children in exposure group (3.3±0.4) kg (P=0.019). At 18 months, the average head circumference was significantly greater among children in control group (47.3±1.3) cm than children in exposure group (47.0±2.0) cm (P=0.038). Additional, mean birth weeks, height, weight, increases in height/weight/head circumference each month, weight/height/head circumference for age Z scores, proportion of growth retardation and low weight, disease prevalence were not observed statistically differences between two groups (P>0.05). All children born to HBsAg-positive mothers were received three-dose HBV vaccination. The rate of hepatitis B immunoglobulin for births born to HBsAg-positive was 98.8% (338/342). Mother to children transmission of HBV at 18 months was 1.0% (1/97). Conclusion: No significant differences in growth development and disease prevalence were found among children born to HBsAg-positive women and women without HBV infection.

Abstract
Objective: To measure the inner diameter of tracheal(TD) in Chinese adults by multi-slice spiral CT(MSCT), multi-planar reconstruction(MPR) with special window technique and analyze its influencing factors. Methods: A total of 824 normal adults(male 435, female 389) and 16 patients with small peripheral pulmonary nodules(SPN) receiving chest multi-slice spiral CT (MSCT) in the physical examination at the First Affiliated Hospital of Guangzhou Medical University between January, 2014 and December, 2015 were included and their records were retrospectively analyzed. The 16 patients with SPN received bronchoscopy and the images were recorded followed by measurement of tracheal diameter using software. MSCT and MPR images were obtained by the 3Dview software, and the inner diameter of the trachea at 4 horizontal positions were measured by special window technique (window width 500 Hu, window level 100 Hu): thoracic entrance (TD(1)), aortic arch (TD(2)), 2 cm higher than the carina of trachea (TD(3)) and the narrowest trachea (TD(4)). Results: The results of bronchoscopy and software measurement in 16 patients were consistent with those of MSCT and MPR combined with special window technique (P>0.05). The TD at 4 positions in adult males were larger than those of adult females (P<0.01). The TD values at each position for males and females were as follows: (18.9±1.7) and (15.6±1.3) mm (t=30.9, P<0.01) for TD(1), (18.8±1.6) and (16.1±1.2) mm (t=28.0, P<0.01) for TD(2), (19.0±1.6) and (16.3±1.3) mm (t=26.5, P<0.01) for TD(3), (18.4±1.5) and (15.5±1.1) mm (t=31.3, P<0.01) for TD(4), respectively. The age, weight and BMI were not significantly correlated with the tracheal diameter (P>0.05). The height was linearly correlated with the tracheal diameter: for males, TD(1)=0.071× height (cm) + 6.964 (r=0.249, P<0.05), TD(2)=0.064 × height (cm) + 7.898 (r=0.246, P<0.05), TD(3)=0.074 × height (cm) + 6.533 (r=0.279, P<0.05), TD(4)=0.056 × height(cm) + 8.811(r=0.226, P<0.05); while for females, TD(1)= 0.046× height (cm) + 8.331 (r=0.183, P<0.05), TD(2) = 0.058 × height (cm)+ 6.950(r=0.248, P<0.05), TD(3)=0.059 × height (cm)+ 7.052 (r=0.235, P<0.05), TD(4) =0.044× height (cm) + 8.520 (r=0.208, P<0.05). Conclusion: MSCT and MPR combined with special window technique are accurate and feasible for the measurement of adult tracheal diameter. The diameter of the trachea in males is larger than that in females, and it is positively correlated with height, but not with age, body weight and BMI. The tracheal diameter can be evaluated by linear regression equation.

Abstract
Objective: To explore the risk factors for lower extremity amputation in patients with diabetic foot. Methods: The clinical data of 1 771 patients with diabetic foot at the Air Force General Hospital of PLA from November 2001 to April 2015 were retrospectively analyzed. The patients were divided into the non-amputation and amputation groups. Within the amputation group, subjects were further divided into the minor and major amputation subgroups. Binary logistic regression analyses were used to assess the association between risk factors and lower extremity amputation. Results: Among 1 771 patients with diabetic foot, 323 of them (18.24%) were in the amputation group (major amputation: 41; minor amputation: 282) and 1 448 (81.76%) in the non-amputation group. Compared with non-amputation patients, those in the amputation group had a longer hospital stay and higher estimated glomerular filtration rate(eGFR)levels. Fasting plasma glucose (FPG), glycosylated hemoglobin (HbA1c), C-reaction protein (CRP), ESR, ferritin, fibrinogen and WBC levels of the amputation group were higher, while hemoglobin albumin, transferrin, TC, TG, HDL-C and LDL-C were lower than those of the non-amputation group (all P<0.05). The proportion of hypertension(52.48% vs 59.98%), peripheral vascular disease (PAD)(68.11% vs 25.04%), and coronary heart disease(21.33% vs 28.71%)were different between the amputation and non-amputation groups (all P<0.05). Multivariable logistic regression analyses showed that Wagner's grade, PAD and CRP were the independent risk factors associated with lower extremity amputation in hospitalized patients with diabetic foot. Conclusion: Wagner's grade, ischemia of lower limbs and infection are closely associated with amputation of diabetic foot patients.

Abstract
Mineral salt bricks are often used in cow raising as compensation for mineral losses to improve milk yield, growth, and metabolic activity. Generally, effects of minerals are partially thought to result from improvement of microbial metabolism, but their influence on the rumen microbiota has rarely been documented to date. In this study, we investigated the response of microbiota to mineral salt in heifer and adult cows and evaluated ruminal fermentation and enteric methane emissions of cows fed mineral salts. Twelve lactating Holstein cows and twelve heifers fed a total mixed ration (TMR) diet were randomly allocated into two groups, respectively: a treatment group comprising half of the adults and heifers that were fed mineral salt and a control group containing the other half fed a diet with no mineral salt supplement. Enteric methane emissions were reduced by 9.6% (P < 0.05) in adults ingesting a mineral salt diet, while concentrations of ruminal ammonia, butyrate, and propionate were increased to a significant extent (P < 0.05). Enteric methane emissions were also reduced in heifers ingesting a mineral salt diet, but not to a significant extent (P > 0.05). Moreover, the concentrations of ammonia and volatile fatty acids (VFAs) were not significantly altered in heifers (P > 0.05). Based on these results, we performed high-throughput sequencing to explore the bacterial and archaeal communities of the rumen samples. Succiniclasticum and Prevotella, two propionate-producing bacteria, were predominant in samples of both adults and heifers. At the phylotype level, mineral salt intake led to a significant shift from Succiniclasticum to Prevotella and Prevotellaceae populations in adults. In contrast, reduced abundance of Succiniclasticum and Prevotella phylotypes was observed, with no marked shift in propionate-producing bacteria in heifers. Methanogenic archaea were not significantly abundant between groups, either in adult cows or heifers. The shift of Succiniclasticum to Prevotella and Prevotellaceae in adults suggests a response of microbiota to mineral salt that contributes to higher propionate production, which competes for hydrogen utilized by methanogens. Our data collectively indicate that a mineral salt diet can alter interactions of bacterial taxa that result in enteric methane reduction, and this effect is also influenced in an age-dependent manner.

Abstract
Pancreatic cancer is characterized by rapid onset, high malignancy and high mortality, thus its early diagnosis is effective for improving the survival rate of patients. To discuss the values of detection of carbohydrate antigen (CA) 50, CA242 and CA199 in the diagnosis of pancreatic cancer, this study randomly selected 112 patients who were confirmed as having stage Ia~IIb pancreatic ductal adenocarcinoma (PDAC) in the Shandong Provincial Hospital, China, from May 2012 to May 2013 as a malignant group. One hundred patients with benign pancreatic lesions and 90 healthy people were selected in the same period as a benign group and a healthy control group, respectively. The levels of serum CA199, CA242 and CA50 were detected using electrochemiluminescence. Results demonstrated that the levels of serum CA199, CA242 and CA50 of the malignant group were significantly higher than those of the benign group and the healthy control group (P=0.001; P=0.003; P=0.000). The positive rate of the tumor markers of the malignant group was higher than that of the benign group and the healthy control group, and the differences had statistical significance (P=0.006; P=0.004; P=0.005). In the malignant group, sensitivity of CA199 was the highest (81.42%) as was the specificity of CA242 (80.14%). The detection of two or more markers could improve sensitivity (joint detection based on parallel tests) and specificity (joint detection based on serial tests). Thus the levels of serum tumor markers including CA199, CA242 and CA50 could be used as the assisted indicators for the diagnosis of early-stage PDAC. Joint detection of the three tumor markers is of great significance to improve the diagnostic sensitivity and accuracy of early PDAC.

Abstract
Objective:To explore the possibility of endoscopic nasolacrimal duct decompression surgery for the treatment of chronic dacryocystitis.Method:①Twenty-two eyes with chronic dacryocystitis were treated with 30% iohexol injection for lacrimal sac lithography. Contrast agents were taken from the lacrimal canal reflux to stop the injection. The CT scan for the lacrimal passage was performed immediately. ②Three-dimensional reconstruction of lacrimal duct and its surrounding structures was performed with Sinuses Trachea Ⅰ software. ③The lacrimal sac and nasolacrimal canal were cut and depressed using this software simulation.Result:①The incidence of lacrimal duct obstruction were 4.5% (1/22, in lacrimal duct), 22.7%(5/22, in lacrimal sac), 13.6%(3/22, transition section), 36.4%(8/22, in nasocrimal duct), and 22.7%(5/22, in Hasner valve) separately. The transitional section, nasolacrimal duct, Hasner valve section 72.7%(16/22) totally. ②The lateral wall of the nasolacrimal duct in 3D visual model is constructed of maxillary lacrimal process. The interior wall of the nasolacrimal duct is made of drop process of lacrimal bone and ascending lacimal process of the inferior turbinate. ③Observed from the inferior meatus, hard nasolacrimal duct is surrounded by inferior turbinate bone, and forms the inside wall of openings of the lacrimal duct. ④The removal of the front parts of the inferior turbinate attached to the lateral nasal can lead to the deperession of the membranous nasolacrimal duct sufficiently, and create the efficient space to eliminate nasolacrimal duct obstruction. Conclusion:Endoscopic nasolacrimal duct decompression surgery is efficacy for the treatment of chronic dacryocystitis. The integrity of the membranous lacrimal duct was reserved, and the complication such as lacrimal sac granulation hyperplasia, lacrimal duct obstruction again caused by scar formation was avoided.

Methods: In February 2016, the data on occupational disease report cards in the occupational disease and occupational health information system from 2006 to 2015 were collected to perform a comprehensive analysis of the types, incidence trend, population characteristics, and enterprise characteristics of occupational diseases. Results: There were 845 new cases of occupational diseases in Ningbo from 2006 to 2015, among which 596 (70.53%) were pneumoconiosis; there were 445 (74.66%) cases of stage I pneumoconiosis, 73 (12.25%) cases of stage II pneumoconiosis, and 78 (13.09%) cases of stage III pneumoconiosis; silicosis (59.76%) was the most common type of pneumoconiosis. Of all patients with occupational diseases, 84.97% were male, 64.50%were aged 35-55 years, and 63.67% had 5-20 working years. Most of the patients with occupational diseases worked in small and medium-sized private (or foreign) enterprises; the most common industries were black metal smelting and rolling (38.76%) , construction (17.11%) , and non-metallic ore mining (13.09%) . A total of 51.28%, 10.26%, and 7.69% of the patients with occupational poisoning worked in the electric apparatus manufacturing industry, furniture manufacturing industry, and chemical raw material and chemical product manufacturing industry, respectively. The cases of occupational diseases are mainly distributed in Yuyao City (24.62%) , Yinzhou District (23.91%) , and Ninghai County (15.62%) . Conclusion: Pneumoconiosis is the most common type of occupational disease in Ningbo and most of these patients work in small and medium-sized private (or foreign) enterprises. The supervision of small and medium-sized private enterprises should be enhanced to protect workers' health.

Abstract
Generation of intense coherent THz radiation by obliquely incidenting an intense laser pulse on a wire target is studied using particle-in-cell simulation. The laser-accelerated fast electrons are confined and guided along the surface of the wire, which then acts like a current-carrying line antenna and under appropriate conditions can emit electromagnetic radiation in the THz regime. For a driving laser intensity ∼3×10^{18}W/cm^{2} and pulse duration ∼10 fs, a transient current above 10 KA is produced on the wire surface. The emission-cone angle of the resulting ∼0.15 mJ (∼58 GV/m peak electric field) THz radiation is ∼30^{∘}. The conversion efficiency of laser-to-THz energy is ∼0.75%. A simple analytical model that well reproduces the simulated result is presented.

Abstract
OBJECTIVE To investigate the incidence rate and risk factors of acute kidney injury (AKI) after off-pump coronary artery bypass grafting (CABG),and to compare the effects of AKI on complications after operation and major adverse cardiovascular and cerebrovascular events (MACCE) after 3 years' follow-up. METHODS In the study, 299 consecutive patients who underwent scheduled off-pump CABG from January 2010 to March 2012 were included. The patients were divided into AKI group with AKI and control group without AKI after operation. The data during perioperative stage were compared, and multivariable Logistic regression modeling was used to identify the risk factors of AKI. The complications were compared after surgery and the patients were followed up for 3 years to observe the difference of MACCE between the two groups. RESULTS AKI occurred in 37.1% patients (111/299). The elevated serum creatinine levels(Wald=9.276, P=0.002, 95%CI 1.006-1.028), chronic obstructive pulmonary disease(COPD) (Wald=3.469,P=0.063,95% CI 0.950-7.630), decreased left ventricular ejection fraction(LVEF)(Wald=4.414,P=0.036,95% CI 0.965-0.999),and implantation of intra-aortic balloon pump (IABP) before or after operation(Wald=6.745, P=0.009, 95% CI 1.336-7.925)were risk factors of AKI in multivariable logistic regression modeling. More complications occurred in AKI group, such as the duration of mechanic ventilation, the time of ICU and the length of stay post operation, reintubation, pulmonary infection, stroke, hemorrhage of digestive tract, the volume of blood transfusion (plasma and red blood cell) and renal replacement therapy(P <0.05). The difference of mortality rate had no statistical significance between the AKI group and the control group, but two patients died in the AKI group. The difference of MACCE between the two groups had no statistical significance after 3 years' follow-up either. CONCLUSION The incidence of AKI was high (37.1%) after off-pump CABG. The elevated serum creatinine levels, COPD, decreased LVEF,and implantation IABP before or after operation were independent risk factors of AKI in multivariable Logistic regression modeling. More complications occurred in AKI group during perioperative period, but the difference of MACCE between the two groups after 3 years' follow-up had no statistical significance.

Abstract
Interleukin-8 (IL-8) is a mediator of inflammation and plays an important role in regulating immune responses. To date, several studies have tested the association between IL-8 gene polymorphisms and development of coronary artery disease (CAD), but their results have proved to be inconsistent. We conducted an investigation to assess the relationship between the IL-8 -251A/T (rs4073) sequence variant and CAD in a Chinese population. Between April 2013 and January 2015, 217 patients with coronary angiography-confirmed CAD were enrolled in our study, along with 245 control subjects. IL-8 -251A/T genotyping was performed using a polymerase chain reaction-restriction fragment length polymorphism assay. A chi-square test revealed that IL-8 -251A/T genotype distributions significantly differed between CAD patients and control subjects (chi-square = 8.29, P < 0.02). Moreover, multiple-logistic regression analysis showed that individuals carrying TA [odds ratio (OR) = 1.59, 95% confidence interval (CI) = 1.01-2.57] and AA (OR = 2.06, 95%CI = 1.21-3.52) genotypes were at increased risk of CAD compared to those with the TT genotype. Under dominant (OR = 1.75, 95%CI = 1.13-2.73) and recessive (OR = 1.54, 95%CI = 1.02-2.37) genetic models, the IL-8 -251A/T polymorphism also significantly correlated with CAD. In conclusion, our results suggest that this variant is an independent risk factor for CAD development under codominant, dominant, and recessive models.

Abstract
Objective: To understand the prevalence rate and correlative factors of dislipidemia among Shanxi coal miners and to provide evidence for the development of programs on dislipidemia prevention. Methods: We investigated 1 337 mine workers from a Coal Group in April 2016 and collected data related to their blood biochemistry. We then classified the types in accordance with the diagnostic criteria of " Guidelines for prevention and treatment of dyslipidemia in Chinese adults (2007)" , using χ(2) test and unconditional logistic regression model for analysis. Results: The overall prevalence rate of Dislipidemia was 59.1% (790/1 337), with males as 60.4% (708/1 173) and females as 50.0%(82/164) while males appeared higher (χ(2)=6.386, P<0.05). Among the 20-34, 35-49, 50 and above year-old groups, the rates were 68.8%, 58.7%, 49.5%, respectively. Results from the χ(2) test showed that gender, age and body mass index were the influencing factors on dislipidemia (χ(2)=7.117, P<0.01; χ(2)=37.135, P<0.01; χ(2)=7.009, P<0.05), while logistic regression analysis showed that sex, age, body mass index level, systolic blood pressure were significantly associated with dislipidemia (P<0.05). Male miners appeared 1.501 times (OR=1.501, 95%CI: 1.895-2.516) higher than female miners in suffering from the risk of dyslipidemia. In different age groups, risks of dyslipidemia in the 35-49, 20-34 year-old groups were 1.672 (OR=1.672, 95%CI: 1.501-2.392) and 2.369 times (OR= 2.369, 95% CI: 1.275-3.469) higher than the 50 year-old. Group that with high BMI, the risk of dyslipidemia was 1.443 times (OR=1.443, 95%CI: 1.139-1.828) higher than the normal BMI group. Group with abnormal systolic pressure was 1.829 times (OR=1.829, 95%CI: 1.152-2.906) higher than normal systolic pressure group. However, diastolic blood pressure, blood sugar, uric acid, and electrocardiogram findings did not seem to show statistically significant meanings on dislipidemia. Conclusion: Among the coal mine workers, those who were males, aged from 20 to 34, having high blood pressure (systolic blood pressure abnormalities) or with high BMI (≥24.0 kg/m(2)) need to be taken special attention on care and prevention of dislipidemia.

Abstract
Objective: To evaluate the difference of metal metabolism, damage to structure and functional activity in brains between hepatic and cerebral type Wilson disease (WD). Methods: Forty patients with WD, including 20 with cerebral type and 20 with hepatic type, and 20 age-matched healthy controls in the First Affiliated Hospital, Sun Yat-sen University between Jul 2013 and May 2016 were enrolled.All study subjects underwent diffusion tensor imaging (DTI), resting state functional MRI (rs-fMRI) and susceptibility weighted imaging (SWI) of the brain.Six regions of interest (ROIs) were chosen.The values of fractional anisotropy (FA), λ in ROIs were determined on DTI, FA and fiber volumes between ROIs were also determined on DTI.The values of amplitude of low frequency fluctuation (ALFF) and regional homogeneity (REHO) in ROIs were determined on rs-fMRI.The values of corrected phase (CP) were calculated on SWI.The copper and iron content were measured.The difference of imaging and metal metrics between cerebral type and hepatic type WD were evaluated. Results: DTI metrics differed between patients with the cerebral and hepatic types of WD.ALFF values in the caudate nucleus, and thalamus were lower (P=0.037, 0.040), and REHO values in the caudate nucleus were lower (P=0.029), in patients of cerebral type than in hepatic type patients.CP values of the right caudate nucleus and left putamen in cerebral type WD patients were lower than in hepatic type patients (P=0.020, 0.23). The serum iron content of hepatic type WD patients was higher than the normal (P=0.013), and the urine copper content was higher than the cerebral type patients (P=0.021). Conclusions: Metal deposition and damage to the structure and functional activity in the brain may occur in hepatic type WD patients.The structural and functional activity damage of the brain in hepatic type is less severe than that in cerebral type patients, while the metal deposition is not significant different between hepatic and cerebral type.

Abstract
OBJECTIVE To explore the application value of GeneXpert MTB/RIF for detection of extra-pulmonary tuberculosis and resistance to rifampin. METHODS A total of 150 samples were collected, including 33 needle aspirates from lymphoid tuberculosis, 23 needle aspirates from spinal tuberculosis, 49 from tuberculous pleural effusions, 24 from cerebrospinal fluid of tuberculous cephalomeningitis, and 21 urinary sediment samples from renal tuberculosis. Smear microscopy, mycobacterium tuberculosis culture and the MTB/RIF method were used to examine these samples and their positive rates were compared. Rifampin susceptibility tests was performed for culture-positive strains using proportion method, which was compared with the result from GeneXpert MTB/RIF method. RESULTS Of the 150 cases of extra-pulmonary tuberculosis, 17 samples were smear-positive, with a sensitivity of 11.3% (17/150); 30 were culture-positive with a sensitivity of 20.0% (30/150); and 96 were positive by MTB/RIF method with a sensitivity of 64.0% (96/150). There was a significant difference between MTB/RIF method and the culture method (χ(2)=59.61, P<0.01). The differences were also significant when the MTB/RIF method was compared with the smear method (χ(2)=88.60, P<0.01) or compared with culture plus smear methods (χ(2)=4.26, P<0.05). Separately, the differences were statistically significant between GeneXpert MTB/RIF method and other 2 methods for diagnosis of lymphoid tuberculosis (n=33, χ(2)=20.56, P<0.01 vs. culture method; χ(2)=27.13, P<0.01 vs. smear results) while no difference was found between culture and smear method (χ(2)=0.67, P>0.05), spinal tuberculosis (n=23, χ(2)=12.74, P<0.01 vs. culture method; χ(2)=14.81, P< 0.01 vs. smear method), tuberculous pleurisy (n=49, χ(2)=32.34, P<0.01 vs.culture method; χ(2)=49.69, P<0.01 vs. smear method) and renal tuberculosis (n=21, χ(2)=4.20, P<0.05 vs. culture method; χ(2) =8.40, P<0.01 vs. smear results). The sensitivity for tuberculous meningitis had no difference among these 3 methods (n=24, P>0.05). Rifampicin-resistance of the strains from the 30 culture-positive cases of extra-pulmonary tuberculosis (20.0%, 6/30) exhibited agreement with GeneXpert MTB/RIF test. CONCLUSION The simplicity and high sensitivity of GeneXpert MTB/RIF technology make it a good diagnostic test for rapid detection of extra-pulmonary tuberculosis and resistance to rifampin.

Abstract
Objective: To explore the applicability of 2 different models of occupational health risk assessment in wooden furniture manufacturing industry. Methods: American EPA inhalation risk model and ICMM model of occupational health risk assessment were conducted to assess occupational health risk in a small wooden furniture enterprises, respectively. Results: There was poor protective measure and equipment of occupational disease in the plant. The concentration of wood dust in the air of two workshops was over occupational exposure limit (OEL) , and the CTWA was 8.9 mg/m3 and 3.6 mg/m3, respectively. According to EPA model, the workers who exposed to benzene in this plant had high risk (9.7×10-6 ~34.3×10-6) of leukemia, and who exposed to formaldehyde had high risk (11.4 × 10-6) of squamous cell carcinoma. There were inconsistent evaluation results using the ICMM tools of standard-based matrix and calculated risk rating. There were very high risks to be attacked by rhinocarcinoma of the workers who exposed to wood dust for the tool of calculated risk rating, while high risk for the tool of standard-based matrix. For the workers who exposed to noise, risk of noise-induced deafness was unacceptable and medium risk using two tools, respectively. Conclusion: Both EPA model and ICMM model can appropriately predict and assessthe occupational health risk in wooden furniture manufactory, ICMM due to the relatively simple operation, easy evaluation parameters, assessment of occupational- disease-inductive factors comprehensively, and more suitable for wooden furniture production enterprise.

Abstract
Objective: To investigate the prevalence, awareness, treatment and control rate of hypertension among Dongxiang population of Dongxiang county in Gansu province, and analyze risk factors of hypertension in this population. Methods: A total of 1 879 Dongxiang residents of Dongxiang county in Gansu province aged 18 years and over were selected in one town and eight villages by random cluster method from April to June in 2014. All subjects were interviewed and physical examination including blood pressure measurement was performed. Multivariate logistic regression analysis was used to analyze the risk factors of hypertension. Results: Prevalence of hypertension in this population was 21.4%(402/1 879). Prevalence of hypertension increased with aging and was 7.9%(35/441) in 18-39 years old people, and 20.2%(151/749)in 40-59 years old people, and 31.3%(216/689)in ≥60 years old people (P<0.01). There were no gender (male vs. female) difference in prevalence of hypertension in 18-39 years old group (8.0%(20/249)vs. 7.8%(15/192), P>0.05) and 40-59 years old group (19.8%(78/393) vs. 20.5%(73/356), P>0.05), while the prevalence of hypertension was significantly higher in male than in female(34.2%(123/360) vs. 28.3%(93/329), P<0.01)in ≥60 years old group. Prevalence of hypertension was also significantly higher in rural area residents than in county town residents (23.4%(255/1 090) vs.18.6%(147/789), P<0.01). The rates of awareness, treatment and control of hypertension in this population were 24.4%(98/402), 14.7%(59/402) and 5.0%(20/402), respectively. Rates of awareness (22.7%(58/255)vs. 27.2%(40/147), P<0.01), treatment(13.3%(34/255)vs. 17.0%(25/147), P<0.05) and control(3.9%(10/255)vs. 6.8%(10/147), P<0.05) were significantly lower in rural area residents than in county residents. Multivariate logistic regression analysis showed that age, family history of hypertension, high body mass index, less physical activity and more static state were risk factors of hypertension in this population(P<0.05 or 0.01). Conclusions: Prevalence of hypertension is high and awareness, treatment and control rates of hypertension are low in adult residents of Dongxiang county in Gansu province. Hypertension prevention focusing on risk factors control and treatment strategies should be enhanced in this population.
