RESUMO

OBJECTIVE: To determine risk factors associated with the prevalence of chronic obstructive pulmonary disease (COPD) in urban and rural populations in Chengdu. METHODS: A multistage random cluster sampling method was adopted to select participants from four communities in Chengdu. All residents aged 40-70 yr. were eligible to participate in this study, which involved a questionnaire survey, physical examination and portable spirometry. Those with airflow limitations were also given post-bronchodilator testing 15 min after inhalation of a dose of 200 microg salbutamol. We defined a forced expiratory volume in one second/forced vital capacity (FEV1/FVC) of less than 70% as COPD. Logistic regression models were performed to identify risk factors of COPD. RESULTS: Of a total of 1931 eligible participants, 1579 (81.77%) completed the questionnaire and spirometry. About 8.35% were identified with COPD: 7.69% in urban vs. 12.37% in rural (P<0.05). The prevalence of COPD increased with age (P<0.05) in the male and total populations. Rural COPD patients had a higher level of smoking rate and use of coal as fuel for cooking than their urban counterparts (P<0.05). But rural COPD patients had a lower level of BMI, waist circumference, literacy, and average household income per capita than their urban counterparts (P<0.05). The multivariate analysis showed that tobacco smoking index (pack-year), education, age and BMI were predictors of COPD for male patients; whereas, coal fuel usage, income and BMI were predictors of COPD for female patients. CONCLUSION: COPD prevalence is higher in rural areas than in urban Chengdu. Major risk factors of COPD include smoking, coal fuels and BMI.

RESUMO

OBJECTIVE: To investigate the serum lipid levels in rural residents with diabetes and pre-diabetes conditions in Chengdu. METHODS: Random cluster sampling method was employed to select participants of 35-70 year-old rural residents in Chengdu. The participants (n=971) were given standard 75 g oral glucose tolerance tests (OGTT) and divided into five groups: impaired fasting glucose (IFG) group, impaired glucose tolerance (IGT) group, IFG and IGT (IFG+ IGT) group, diabetes mellitus (DM) group and normal glucose tolerance (NGT) group. Their serum total cholesterol (TC), triglyceride (TG), high density lipoprotein cholesterol (HDL-c) and low density lipoprotein cholesterol (LDL-c) were measured. RESULTS: The age-adjusted standardized prevalence of DM and pre-diabetes in rural residents in Chengdu were 12.8% and 34.5%, respectively, without significant gender differences. IGT was the most common type of abnormal glucose metabolism in pre-diabetes. High serum TG and LDL-c and low serum HDL-c were found in 45.9%, 30.6% and 9.9% participants with DM, respectively. High serum LDL-c and TG and low serum HDL-c were found in 38.1%, 30.6% and 7.6% of participants with IGR. Participants with DM or/and IGR had higher levels of LDL-c and TG and lower levels of HDL-c than those in the NGT group. CONCLUSION: Pre-diabetes and diabetes are prevalent in rural residents in Chengdu, which are usually accompanied with various degrees of dyslipidemia.

RESUMO

BACKGROUND: Peripheral T-cell lymphoma (PTCL), an aggressive and rare disease that belongs to a heterogeneous group of mature T-cell lymphomas, develops rapidly and has a poor prognosis. Early detection and treatment are essential to improve patient cure and survival rates. Here, we report a rare case of PTCL with clinical presentation of noncirrhotic portal hypertension, which provides a basis for early vigilance of lymphomas in the future. CASE SUMMARY: A 65-year-old Chinese woman was admitted to our hospital because of abdominal distension for 3 months and pitting oedema of both lower limbs for 2 months. Physical examinations and associated auxiliary examinations showed the presence of hepatosplenomegaly, and her hepatic venous pressure gradient was 10 mmHg. Immunohistochemical analysis of the liver biopsy confirmed the diagnosis of PTCL. The patient underwent combination therapy with dexamethasone, VP-16, and chidamide. Unfortunately, after 41 days of chemotherapy, the patient died of multiple organ failure. CONCLUSION: PCTL accompanied by noncirrhotic portal hypertension is rarely reported. This case report discusses the diagnosis of a patient according to the literature.

RESUMO

Background: The modified Dietary Approaches to Stop Hypertension (DASH) diet was a potentially effective treatment for pre-hypertensive and hypertensive patients. The evidence for the effect of the modified DASH diet on blood pressure reduction was inconsistent. The study was designed to assess the effects of the modified DASH diet on blood pressure (BP) in hypertensive and pre-hypertensive adults. Methods: We searched Medline, Embase, CENTRAL, CNKI, VIP, Wanfang Data, SINOMED, Google Scholar, the World Health Organization's International Clinical Trials Registry Platform, and Clinicaltrials.gov from inception to July 1st, 2021. Randomized controlled trials (RCTs) assessing the effects of the modified DASH diet on systolic and diastolic BP, cardiovascular risk factors (body weight, body mass index, waist circumference, fasting glucose, blood lipids), cardiovascular events, and all-cause mortality were included. Statistical analysis was performed using Stata software. Risk of bias was assessed with the Cochrane tool and quality of evidence with GRADE. Results: A total of 10 RCTs were included. Compared with control diet, the modified DASH diet could reduce mean systolic (-3.26 mmHg; 95% confidence interval -5.58, -0.94 mmHg; P = 0.006) and diastolic (-2.07 mmHg; 95% confidence interval -3.68, -0.46 mmHg; P = 0.01) BP. Compared with the controlling diet, the modified DASH diet could reduce systolic BP to a greater extent in trials with a mean baseline BP ≥ 140/90 mmHg compared with <140/90 mmHg. Diastolic BP reduction was greater when the mean body mass index was ≥30 kg/m2 than <30 kg/m2. Diastolic BP reduction was more marked in trials with a follow-up time of >8 weeks compared with ≤8 weeks. The modified DASH diet could affect mean waist circumference (difference: 1.57 cm; 95% confidence interval -2.98, -0.15) and triglyceride concentration (difference: 1.04 mol/L; 95% confidence interval -1.47, -0.60). Conclusions: The modified DASH diet can reduce BP, waist circumference, and triglyceride concentration in hypertension patients. A higher baseline BP is associated with more marked systolic and diastolic BP reduction. Systematic Review Registration: PROSPERO registration number: CRD42020190860.

RESUMO

To complement the molecular pathways contributing to Parkinson's disease (PD) and identify potential biomarkers, gene expression profiles of two regions of the medulla were compared between PD patients and control. GSE19587 containing two groups of gene expression profiles [6 dorsal motor nucleus of the vagus (DMNV) samples from PD patients and 5 from controls, 6 inferior olivary nucleus (ION) samples from PD patients and 5 from controls] was downloaded from Gene Expression Omnibus. As a result, a total of 1569 and 1647 differentially expressed genes (DEGs) were, respectively, screened in DMNV and ION with limma package of R. The functional enrichment analysis by DAVID server (the Database for Annotation, Visualization and Integrated Discovery) indicated that the above DEGs may be involved in the following processes, such as regulation of cell proliferation, positive regulation of macromolecule metabolic process, and regulation of apoptosis. Further analysis showed that there were 365 common DEGs presented in both regions (DMNV and ION), which may be further regulated by eight clusters of microRNAs retrieved with WebGestalt. The genes in the common DEGs-miRNAs regulatory network were enriched in regulation of apoptosis process via DAVID analysis. These findings could not only advance the understandings about the pathogenesis of PD, but also suggest potential biomarkers for this disease.
