Background: Hypertension is estimated to cause 4.5% of the global disease burden. The prevalence of hypertension in Malaysia is 32.2%. Objective: To determine the prevalence of hypertension and its associated risk factors in two rural communities in Penang, Malaysia. Methods: This cross sectional study was conducted among all consenting residents aged 18 years and above from two villages in Penang. Besides the baseline demographic information, blood pressure was measured using a manual sphygmomanometer according to the American Heart Association Guidelines. Results: 50 out of 168 people were hypertensive, giving a prevalence rate of 29.8%. 50.0% of those found with hypertension were undiagnosed and 48.0% of those who were diagnosed with hypertension had uncontrolled blood pressure. Logistic regression analysis showed that age, history of alcohol consumption and BMI were found to be independently associated with hypertension. Conclusions: Age, education level, alcohol consumption and BMI are important risk factors associated with the prevalence of hypertension among the villagers. These risk factors are comparable to those reported in National Health and Morbidity Survery 2006 in Malaysia.

Objective To measure and analyze the set-up errors of postoperative intensity modulated radiation therapy of rectal cancer (PIMRTRC)with electronic portal imaging device (EPID),and to provide theoretical foundation for clinical realizing of accurate PIMRTRC.Methods Totally 30 patients after rectal carcinoma resection underwent sagittal and coronal photographing with EPID before the first time of therapy and one time per week during the treatment course.The obtained images were compared with DRR images in treatment planning system to get the setup errors at X(left-right),Y(head-foot) and Z (front-back)directions,and the extending margins of CTV and PTV in postoperative intensity modulated radiation therapy were calculated.EPID was used for setup correction,and SPSS 19.0 was involved in to execute statistical analysis. Results The linear displacement had the mean values plus/minus standard deviation at X, Y and Z directions before and after error correction being(-1.392 4±3.670 9)mm vs(-0.816 5±2.670 5)mm,(0.969 7±4.076 1)mm vs(0.418 2±2.911 4)mm, and(0.704 4±1.805 6)mm vs(0.471 7±1.641 3)mm respectively;the extending margin had the values being 7 mm vs 5 mm, 6 mm vs 4 mm, and 4 mm vs 3 mm respectively.Conclusion EPID ensures the correctness and accuracy in postoperative intensity modulated radiotherapy of rectal cancer,which makes target area gifted with maximized dose,the surrounding tissue and organs at risk protected adequately,and provides theoretical support for extending CTV margin.[Chinese Medical Equip-ment Journal,2018,39(5):59-63]

OBJECTIVETo detect Beclin1 expression and explore its clinical significance in primary hepatocellular carcinoma (HCC).

METHODSBeclin1 expressions in 10 normal hepatic tissues, 30 hepatitis liver, 30 cirrhotic liver and 50 HCC tissues were detected by immunohistochemical staining.

RESULTSThe positivity rates of Beclin1 expression in the HCC, cirrhotic liver, hepatitis liver and normal liver tissues were 78.00% (39/50), 26.67% (8/30), 53.33% (16/30), and 10.00% (1/10), respectively, showing significant differences between them (chi(2)=28.31, P<0.05). Beclin1 expression was significantly higher in HCC tissues than in the cirrhotic, hepatitis and normal liver tissues (chi(2)=20.39, 5.31, and 14.41, respectively, P<0.05), and hepatitis tissues showed significantly higher Beclin1 expression than hepatic cirrhosis tissues and normal hepatic tissues (chi(2)=4.44 and 4.12, respectively, P<0.05).

CONCLUSIONThe abnormal expression of Beclin1 is closely associated with the pathogenesis and development of primary hepatocellular carcinoma, and may play an important role in this process.

Abstract: Objective　To analyze the epidemiological characteristics (season, age, gender, mixed infection and clinical manifestations, etc.) of Mycoplasma pneumoniae (MP) infection in children in Hainan Province, so as to provide epidemiological evidence-based medical basis for the prevention and control of MP infection in children in Hainan Province. Methods　The serum IgM antibodies of MP, Legionella pneumophila, Chlamydia pneumoniae, adenovirus, respiratory syncytial virus (RSV), Q fever Rickettsia, parainfluenza virus, influenza A virus and influenza B virus in children with respiratory tract infections (RTIs) who were hospitalized in pediatrics of many hospitals in Hainan Province from March 2012 to February 2020 were detected by indirect immunofluorescence method. The positive serum MP-IgM antibody was defined as MP infection. The epidemiological and clinical data of MP infected cases were analyzed retrospectively. Results　From March, 2012 to February, 2020, a total of 35 731 qualified pediatric inpatients with RTIs in many hospitals in Hainan Province were tested for serum MP-IgM with the total positive rate of 39.12% (13 978/35 731). The yearly positive rates of MP-IgM from 2012 to 2020 were 48.39%, 56.23%, 56.62%, 47.04%, 29.71%, 24.14%, 47.55%, 36.84% and 24.46% respectively. The positive rates of MP-IgM in 2013 and 2014 were significantly higher than those in other years (P<0.05). The positive rate of MP-IgM in summer in Hainan Province was the highest (41.34%) and the lowest in winter (35.77%) (P<0.05). MP infection occurred in all age groups, the positive rate of MP-IgM in children of preschool (51.80%) was significantly higher than that in other age groups (P<0.01), and the positive rate of MP IgM in children of infancy (15.36%) was lower than that in other age groups (P<0.01). The positive rate of MP-IgM in female was 44.77%, which was significantly higher than that in male (35.83%) (P<0.05). MP infection combined with positive IgM of another pathogen accounted for 32.63% (4 561 cases), positive IgM of another two pathogens accounted for 1.26% (176 cases). MP infection was mostly found in pneumonia (68.73%), and the main clinical symptoms were cough (84.72%), fever (51.01%) and wheezing (3.16%). Conclusions　MP is an important pathogen of respiratory tract infection in children in Hainan Province, and infection is more common in children in early school age and early childhood. Mp-specific tests should be performed to identify the pathogen in children suspected of MP infection. In the high incidence season, health education should be strengthened in kindergartens, schools and other places to prevent respiratory tract infection.

Purpose: Total neoadjuvant therapy (TNT) is becoming the standard of care for locally advanced rectal cancer. However, surgery is deferred for months after completion, which may lead to fibrosis and increased surgical difficulty. The aim of this study was to assess whether TNT (TNT-RAPIDO) is associated with increased difficulty of total mesorectal excision (TME) compared with long-course chemoradiotherapy (LCRT) and upfront surgery. Methods: Twelve laparoscopic videos of low anterior resection with TME for rectal cancer were prospectively collected from January 2020 to October 2021, with 4 videos in each arm. Seven colorectal surgeons assessed the videos independently, graded the difficulty of TME using a visual analog scale and attempted to identify which category the videos belonged to. Results: The median age was 67 years, and 10 patients were male. The median interval to surgery from radiotherapy was 13 weeks in the LCRT group and 24 weeks in the TNT-RAPIDO group. There was no significant difference in the visual analog scale for difficulty in TME between the 3 groups (LCRT, 3.2; TNT-RAPIDO, 4.6; upfront, 4.1; P=0.12). A subgroup analysis showed similar difficulty between groups (LCRT 3.2 vs. TNT-RAPIDO 4.6, P=0.05; TNT-RAPIDO 4.6 vs. upfront 4.1, P=0.54). During video assessments, surgeons correctly identified the prior treatment modality in 42% of the cases. TNT-RAPIDO videos had the highest recognition rate (71%), significantly outperforming both LCRT (29%) and upfront surgery (25%, P=0.01). Conclusion TNT does not appear to increase the surgical difficulty of TME.

Aim To investigate the protective effect of Huoxue Jiedu recipe on autophagy injury of H9C2 cardiomyocytes induced by hypoxia/reoxygenation and its mechanism. Methods H9C2 cardiomyocytes were used to establish a hypoxia/reoxygenation injury model. The effective concentration was screened and the cell activity was detected by CCK8 assay. The apoptotic rate of myocardial cells was detected by flow cytometry. The expression of autophagy marker LC3 was observed by laser confocal microscopy. The mRNA levels of Beclin-1, LC3 and Bcl-2 were detected by real-time quantitative PCR. The expressions of Beclin-1, LC311/I, Cleaved caspase-3, β-catenin, p-p65, Bcl-2, p62, p-Akt, p-mTOR were detected by Western blot. Results Huoxue Jiedu recipe can enhance the growth activity of myocardial cells and reduce the apoptotic rate and autophagy level, and it can enhance the activation of PI3K/Akt/mTORCl pathway, decrease Beclin-1 and LC3 mRNA levels, while increase Bcl-2 mRNA levels. It also decreased the expression of Beclin-1, LC311/I, Cleaved caspase-3, β-catenin, p-p65, and increased the expression of p62, p-Akt, p-mTOR, and Bcl-2. Conclusions Huoxue Jiedu recipe can reduce the level of autophagy and apoptosis of myocardial cells by regulating the autophagy pathway of PI3K/Akt/mTORCl, thereby playing a protective role in hypoxia/reoxygenation H9C2 myocardial cells.

OBJECTIVETo evaluate the effect of snail control through soil pasting mixed with niclosamide.

METHODSFour sites were selected in different epidemic areas in Sichuan province. Soil pasting mixed with niclosamide was carried on, and the dosage was 0 g/m2, 4 g/m2, 6 g/m2, 8 g/m2 and 10 g/m2 respectively. The mortality rate of snail and the density of snail were observed after 7, 15, 30, 90 and 180 days.

RESULTSThe mortality rate of snail was more than 43.3% in blank group after 30 days. The mortality rate of snail was from 75.3% to 100.0% at 4 g/m2 group after 30 days. The mortality rate of snail in 4 g/m2 group was significantly higher than that in the blank group (chi2 = 31.27, P < 0.05). There was no significant difference in the mortality rate of snail among all study groups (chi2 = 1.07, P > 0.05). The decrease rate of snail density was more than 90%. The mortality rate of snail was about 30% higher in Chantu group than Qutu group. The unit cost of Pasting-Mixing Drug with Soil was from 5 to 7 times of spray method, but the total cost was similar for the. two methods at the endpoint of the snail control.

CONCLUSIONThe effect of soil pasting mixed with niclosamide is good, and the dosage of 4-6 g/m2 is suggested in snail control.
