Objective To analysis of clinical symptoms and influencing factors of anti-platelet aggregation drugs in patients with upper gastrointestinal bleeding.Methods Using the research methods of retrospective analysis, collected 110 cases of gastrointestinal bleeding patients from June 2012 to June 2015 into the first affiliated hospital of xiamen university,and divided into two groups,the control group,79 patients were treated without antiplatelet aggregation drugs,the experimental group,31 patients were treated with single antiplatelet aggregation drug.observed the degree of gastrointestinal bleeding,the mode of bleeding, and the characteristics of endoscopic findings between two groups,according to the age,INR, and the type of drug taken, the clinical symptoms and influencing factors of the patients were analyzed further.Results The rate of gastrointestinal bleeding was significantly higher in the experimental group than in the control group(P<0.05).The older the patient,the higher rate of gastrointestinal bleeding,the main manifestations were gastritis or ulcers in endoscopy,patients with INR>3 had a significantly higher rate of gastrointestinal bleeding than patients with INR<3.Conclusion Anti-platelet aggregation drugs can significantly increase the chance of serious bleeding in the digestive tract,the patient's age, INR value and the type of medication can affect the incidence of gastrointestinal bleeding;long-term use of these drugs lead the most serious impact on the duodenum, can lead to the site intestinal mucosa damage,with the increasing age of patients,adverse reactions of the digestive tract increased.

Objective To investigate the clinical significance of contrast-enhanced transrectal ultrasound(CE-TRUS) in the perineal prostate biopsy. Methods A total of 116 patients was undergone prostate biopsy through the perineum under the direction of tansrectal ultrasound. Prostate biopsy standard was based on 2007 CUA revised guidelines for diagnosis and treatment of urological diseases.Color Doppler ultrasonography was used to check the prostate and to learn the prostate focal lesion,size, number and echo color Doppler flow characteristics. Of the 116 cases, 43 patients was undergone contrast-enhanced transrectal ultrasound. Results The biopsy results confirmed the diagnosis of prostate cancer was 64 cases, Benign prostatic hyperplasia was 52 cases. Of 43 cases who undergone contrast-enhanced transrectal ultrasound, Prostate cancer and Benign prostatic hyperplasia were 25 and 18 cases, respectively. CE-TRUS group and TRUS group showed no statistical difference between two groups. Analyzed the cases with PSA≤30 ng/ml, CE-TRUS group had a higher positive rate of biopsy (P=0.046). Conclusion TRUS guided transperineal biopsy of prostate might be an method for the diagnosis of prostate cancer with a higher accuracy rate. CE-TRUS can improve the biopsy positive rate of prostate cancer.

Objective: Strategy for wound repair of skin and soft tissue defect and systematic rehabilitation treatment for functional reconstruction of patients with severe burn or trauma on knees. Methods: From January 2015 to October 2016, 26 patients with skin and soft tissue defect on knees after severe burn or trauma were hospitalized in our unit. Among these patients, 14 patients had patellar ligament defect, and 16 patients had knee joint capsule defect. Wound debridement was operated on 1 to 3 days after admission. After debridement, the area of skin and soft tissue defect ranged from 10 cm×7 cm to 42 cm×18 cm. Vacuum sealing drainage (VSD) treatment was performed after debridement, and flap transplantation operation was performed after VSD treatment for 5 to 7 days. Defects of nine patients were treated with local rotation flaps. Seven patients with skin and soft tissue defects on knees and knee joint capsule defects of 5 cm×3 cm to 9 cm×7 cm were treated with free anterolateral femoral flaps combined with fascia lata. Ten patients with skin and soft tissue defects on knees and patellar ligament defects of 6 cm×3 cm to 12 cm×4 cm were treated with free anterolateral femoral flaps combined with iliotibial tract. The area of flaps ranged from 11 cm×9 cm to 22 cm×15 cm. After flap transplantation operation, functional reconstruction of knee joint was carried out according to early, continuous, and sequential systematic rehabilitation treatment strategy. The pain degree and function of knee joint of patients were scored by the International Knee Documentation Committee (IKDC) Knee Evaluation Form before operation and 12 months after operation. The knee joint flexion and extension degrees of patients were measured by joint protractor in 2 weeks and 12 months after operation. The color Doppler ultrasound was used to evaluate integrity of knee joint capsule and continuity of patellar ligament of patients in 6 and 12 months after operation. Results: All flaps of 26 patients survived well, and wounds healed completely after the operation. Distal parts of flaps of 2 patients treated with free anterolateral femoral flaps had local necrosis after the operation, and their wounds healed after debridement and transplantation of autologous intermediate split-thickness skin graft of thigh. The IKDC Knee Evaluation Form score of patients was (79±8) points in 12 months after operation, which was significantly higher than (64±7) points before operation (t=7.20, P<0.05). The flexion degree of knee joint of patients was (117±10)° in 12 months after operation, which was significantly larger than (35±8)° in 2 weeks after operation (t=32.65, P<0.05). The extension degree of knee joint of patients was (12±9)° in 12 months after operation, which was significantly smaller than (61±9)° in 2 weeks after operation (t=19.63, P<0.05). In 6 and 12 months after operation, 9 patients treated with local rotation flaps had good integrity of knee joint capsule and continuity of patellar ligament; 7 patients treated with free anterolateral femoral flaps and fascia lata had good integrity of knee joint capsule; 10 patients treated with free anterolateral femoral flaps and iliotibial tract had good continuity of patellar ligament. During follow-up of 12 months, all flaps survived well; knees of all patients had good appearance; knee joints functioned normally. Conclusions Good appearance and function of knees can be achieved by repairing wound of skin and soft tissue defect on knees after severe burn or trauma with local rotation flaps or free anterolateral femoral flaps with fascia lata or iliotibial tract plus systematic rehabilitation treatment of knee joint in early stage after flap transplantation operation.

Objective:To investigate the changes of reactive oxygen species (ROS) in pancreatic cancer cells under the effect of pulsed electric fields (PEF).Methods:Murine-derived pancreatic cancer cells Panc02 were treated with PEF at electric field strengths of 0, 250, 500, 750, and 1 000 V/cm, respectively. The intracellular ROS generation patterns under the different field strengths and at different times after the PEF were investigated in vitro by flow cytometry and immunofluorescence, meanwhile exploring the apoptosis of murine and human pancreatic cancer cells under different field strengths. Twenty 6- to 8-week-old male C57BL/6 SPF mice were prepared as orthotopic pancreatic cancer models and divided into five groups of four mice each: 250 V/cm PEF group, 500 V/cm PEF group, 750 V/cm PEF group, 1 000 V/cm PEF group, and sham operation group. ROS expression in the residual tumor tissues of mice in each group was detected by immunofluorescence.Results:Under the 500 V/cm, 750 V/cm and 1 000 V/cm electric field strength, the proportion of cells with intracellular ROS expression was decreased after 6 h, 12 h, 24 h and 48 h of the PEF compared with 2 h after the PEF, and the differences were statistically significant (all P<0.05). Compared with 0 V/cm PEF group, ROS expression increased in Panc02 cells treated with 500 V/cm and 750 V/cm PEF groups, and the differences were statistically significant (all P<0.05). Compared with 250 V/cm PEF group under the same time, ROS in Panc02 cells treated with 500 V/cm and 750 V/cm electric field strengths increased, and the differences were statistically significant (all P<0.05). The proportions of apoptosis of both Panc02 cells and MIA-PaCa-2 cells increased with rising field strength and peaked at the field strength of 750 V/cm. Compared with the sham-operated group, the expression of ROS was increased in pancreatic cancer tissues of mice in the 500 V/cm PEF-treated group (16.65±6.01 vs. 2.38±1.21, t=-6.53) and 750 V/cm PEF-treated group (16.54±4.41 vs. 2.38±1.21, t=-6.48), and the differences were statistically significant in both cases (both P<0.001). Conclusion:PEF treatment was able to increase the level of ROS in both pancreatic cancer cells and tissues, and more ROS were produced when the electric field strength was 500 and 750 V/cm.

Objective: To analyze the longitudinal change of serum total cholesterol concentration in 733 rural residents in Shanxi province. Methods: Based on the residents of five rural areas in Shanxi province who participated in China nutrition and health survey in 2002, a follow-up survey was conducted in 2015. Fasting venous blood of the participants was collected and serum TC concentration was tested by cholesterol oxidase method. Results: Of 733 participants, 332 were male and 401 were female. In 2002 baseline survey, the age of the participants was (42.6±9.5) years old, 76.2% of male and 83.8% of female had junior middle school education or below. Proportion of smoking were 65.7% and 1.2%, drinking were 26.8% and 4.0%, obesity were 6.3% and 12.0%, and central obesity were 27.1% and 31.9%, respectively in male and female. The follow-up age of participants in 2015 was (55.8±9.5) years old, proportion of smoking changed to 48.2% and 1.5%, drinking were 49.7% and 3.0%, obesity increased to 11.8% and 18.2% and central obesity increased to 41.6% and 53.6%, respectively in male and female. The overall serum TC level increased from (3.82±0.89) mmol/L to (4.72±0.97) mmol/L with an average increase of 27.2%, which increased from (3.84±0.94) mmol/L to (4.54±0.93) mmol/L in male with an average increase of 22.7%, and increased from (3.81±0.84) mmol/L to (4.86±0.98) mmol/L in female with an average increase of 30.9%. The serum TC levels in 18-, 30-, 40-, and 50-59 years old group increased from (3.42±0.83), (3.72±0.77), (3.90±0.83) and (4.00±1.03) mmol/L to (4.38±1.01), (4.79±0.92), (4.73±0.99) and (4.76±0.96) mmol/L, with average increase range of 31.4%, 32.1%, 25.2% and 22.6%, respectively. The mean serum TC levels between two years all had statistically significant difference among groups of gender, age, education, marital status, family history of cardiovascular disease, smoking, drinking, BMI and waist circumference after paired t-test and ANOVA analysis (P<0.01). Conclusion The longitudinal serum TC level of rural residents in Shanxi province increased rapidly.

Objective: To explore the association between dietary pattern which benefit for normal kidney function and the risk of cognitive decline or impairment in the elderly. Methods: In 2015, subjects aged 60 and over from four counties in the Nutrition and Chronic Disease Family Cohort project, were followed up in 2017. Cognitive function was repeatedly assessed, using the Mini Mental State Evaluation (MMSE) scale. Dietary pattern that benefit for normal kidney function was extracted, using the reduced rank regression method and followed by logistic regression models to explore the associations between scores that showing the kidney function on dietary patterns and the risk of cognitive deterioration and impairment in two years among those who were with normal cognition in 2015. Results: Dietary pattern that benefit for normal kidney function, was characterized by high consumption of cereal, vegetables, legume and fruits but with less meat and soy products. Comparing with the group with lowest score quartile on this dietary pattern, the risk of cognitive deterioration in the highest quartile group was significantly low (P<0.01) in two years, with an odds ratio as 0.57 (95%CI: 0.37-0.85). Linear trend was also obviously visible (P=0.007) in this group. The ones at the highest quartile group among the normal cognition ones in 2015, the risk of cognitive impairment also significantly reduced (P<0.05) in two years time, with an odds ratio as 0.52 (95%CI: 0.29-0.93). Also, linear trend could obviously be seen (P=0.01). Conclusion Dietary pattern that benefit for normal kidney function was both inversely associated with cognitive deterioration and impairment, in two years.

Objective: To assess the relationship between body mass index (BMI) and mortality in adults of Shanxi, China. Methods: Baseline data were from the '2002 China Nutrition and Health Survey’ in Shanxi province. All the death-related investigation and follow-up visits were carried out from December 2015 to March 2016. The follow-up program covered 5 360 people from all the 7 007 participants aged 18 years and over that having complete core information, with a rate as 76.5%. Participants of this study were divided into eight groups, according to the appearance of BMI. Taking the group with the lowest mortality density as the reference group, Cox regression model was used to estimate the hazard ratio (HR) and 95% confidence interval (CI) of deaths by the whole population, gender and age groups (≥60 years, <60 years). Results were then adjusted by age, gender, smoking, alcohol use and education level from the baseline survey. Sensitivity analysis was also conducted. Results: Results from the study showed that among the total number of 67 129 person- years from the average period of 12.5 years, there were 615 deaths occurred, with the mortality density as 916 per 100 000 person-years. Taking the BMI range of 26.0-27.9 kg/m² as the reference, the aHRs of death increased to 1.90 (95%CI: 1.26-2.86), 1.68 (95%CI: 1.15-2.45), 1.49 (95%CI: 1.08-2.06) and 1.72 (95%CI: 1.07-2.76) after the multivariate adjustment, in these four groups (BMI<18.5, 18.5-19.9, 22.0-23.9 and ≥30.0 kg/m²), respectively. Low body weight (BMI<18.5 kg/m²) was associated with higher risks of death in the elderly of ≥60 years, with the aHR of death as 1.94 (95%CI: 1.20-3.15). Conclusions When BMI appeared as ≤19.9 kg/m², 22.0-23.9 kg/m² and ≥30.0 kg/m², the risks of death would increase. In addition to programs that focusing on obesity, special attention should be paid to the high risk of mortality which was caused by low-weight and malnutrition in the elderly.

Objective: To analyze the blood pressure changes of adults aged 18-59 years in rural area of Shanxi province based on a cohort study, and provide reference for the study of the blood pressure level of rural residents and hypertension prevention and control in rural areas in China. Methods: Data were obtained from Shanxi Nutrition and Chronic Disease Family Cohort from 2002 to 2015. Subjects aged <18 years or ≥60 years and individuals with hypertension at baseline survey in 2002, and those who had taken antihypertensive drugs for nearly two weeks during the follow-up survey in 2015 were excluded from the study. A total of 1 629 subjects aged 18-59 years were included in the analyses of the blood pressure level and its change from the baseline survey in 2002 to follow-up survey in 2015. Results: The systolic blood pressure (SBP) of the subjects increased from (122.7±10.4) mmHg in 2002 to (132.8±17.6) mmHg in 2015 and the diastolic pressure (DBP) increased from (72.7±6.9) mmHg in 2002 to (78.8±10.3) mmHg in 2015. The SBP in men and women increased with growth rates of 6.7% and 9.5%. While DBP in men and women increased with growth rates of 9.3% and 7.8%. The SBP levels of those aged 18-, 30-, 40- and 50-59 years increased with growth rates of 5.0%, 6.7%, 9.4% and 11.8%. While the DBP of these age groups increased with growth rates of 12.2%, 8.2%, 8.2% and 6.5%. Conclusions The blood pressure of adults aged 18-59 years old in rural area of Shanxi showed a substantially increasing trend. The mean increase level of SBP in women was higher than that in men, and increased with age. While the mean increase level of DBP in men is higher than that in women, and decreased with age.
