Objective: To investigate the prevalence and risk factors of bronchial asthma in the Li ethnic group in Hainan, China. Methods: This study employed a stratified random sample design using custom-designed questionnaires. Subjects with asthma-like symptoms were first identified by two rounds of surveys and then confirmed by respiratory physicians using pulmonary function test, bronchial dilation test and challenge test. Demographic data, information on family history of asthma, history of allergies, smoking habits, domestic cooking fuel and other potential risk factors were collected. Logistic regression was performed to evaluate risk factors for asthma. Results: The prevalence of asthma in the Li ethnic group was 3.38%, much higher than the national average level in China. Aging, agriculture industry (the rubber industry in particular), rural residence, family history of asthma, history of allergies, cold air, inhalation of dust and irritant gases, smoking, domestic cooking fuel and living environment were associated with increased risk of asthma. Conclusions: The high prevalence of asthma in the Li ethnic group highlights the importance of asthma prevention and treatment in this population. Risk factors indentified in this study warrant special attention. Elevating public awareness about asthma in local communities will benefit the prevention of the disease. © 2012 Hainan Medical College. Source

Survivors of ischemic stroke are still at a significant risk for recurrence. Numerous effective strategies for the secondary prevention of ischemic stroke have now been established; however, these guidelines are not widely known. In this retrospective, a multicenter study was conducted from January 2011 to February 2012 in 10 general hospitals, which included 1300 elderly patients who had previously been diagnosed with ischemic stroke and re-admitted to hospitals. Logistic regression models were fitted to determine the relationship between compliance with secondary prevention therapy and each variable of interest. The treatment rates of antihypertensive, antiplatelet and lipid-lowering therapy were only 56.3%, 48.9% and 19.6%, respectively. Multivariate analysis presented that cardiovascular risk factors would motivate patients with hypertension and hyperlipidemia to receive corresponding treatments. However, it is worth noting that they did not influence the use of antiplatelet therapy. In addition, high education, health education and insurance promote the use of secondary prevention in patients. In conclusion, the importance of antiplatelet therapy should not be ignored any more. Besides, health education will raise patients' attention to ischemic stroke. © The Author(s) 2013 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav. Source

BACKGROUND: In recent years, some researchers began to apply a relatively non-invasive multi-slice spiral computerized tomography (CT) to replace digital subtraction angiography (DSA) to evaluate renal anatomy and function of kidney transplantation, but the relevant reports mainly focused on that in the 16-slice (or below) spiral CT, few on the 64-slice spiral CT. OBJECTIVE: To evaluate the value of 64-slice spiral CT three-dimensional reconstruction in donor and recipient kidney for renal transplantation. METHODS: Seven patients who were voluntary to donate their one kidney to their relatives and 6 patients who were about to receive kidney from others were done plain CT scan, arterial phase, venous phase and delayed phase enhanced scanning, and enhanced scanning periods were processed with three-dimensional reconstruction techniques including multi planar reconstruction, volume rendering technique, maximumintensity projection and curved projection reconstruction. RESULTS AND CONCLUSION: In 7 donors, according to CT angiography, one renal artery in each side of the kidneys was presented in 4 cases, two renal arteries in the left kidney and one in the right in 1 case, three renal arteries in the left kidney and two renal arteries in the right in 2 cases; one renal vein and one set of renal pelvis and ureter were presented in both left and right kidney in all cases. MPR reconstruction showed left renal cyst in 1 case, kidney functions were normal in all cases according to CT urography. The above mentioned results shown by 64-slice spiral CT three-dimensional reconstruction were all proven by surgery. In recipients, according to CT angiography, renal artery, vein and ureter were no stricture and fistula in all 6 cases. CT scanning of 4 cases of the transplanted kidneys showed normal size, normal shape and density. Arterial phase enhanced scanning showed clear boundaries in renal cortex and renal medulla, and CT values were greater than 150 HU. Venous phase enhanced scanning showed the renal parenchyma uniform, CT urography showed urinary function normal. Artery enhanced scanning of 2 cases of the transplanted kidney showed unclear boundaries in renal cortex and renal medulla, CT values less than 100 HU. Venous phase enhanced scanning showed the kidney parenchyma were weak, delayed 10-minute scanning showed only a small amount of contrast medium excretion, which confirmed rejection by renal biopsy. 64 slice spiral CT three dimensional reconstruction can basically replace other imaging examinations before and after renal transplantation, and can be the best option for renal transplantation.

AIM: To evaluate the feasibility, efficacy and safety of endoscopic ultrasound-assisted endoscopic submucosal resection (ESR) of tumors originating from the muscularis propria of the esophagus. METHODS: Twelve patients with esophageal submucosal tumors revealed by gastroscopy were included in this study. Endoscopic ultrasound revealed that all tumors were located in the muscularis propria of the esophagus. Endoscopic submucosal resection was performed in all patients. The entire operation was performed under general anesthesia in the operating room. Gastroscopy was performed again one and three months postoperatively. RESULTS: The operation duration ranged from 90 to 150 min, with an average value of 100 min. The size of tumors ranged from 1.1 to 2.2 cm, with an average value of 1.5 cm. All the tumors were resected en bloc. Postoperative pathological examination and immunohistochemical staining revealed leiomyoma in 11 patients and interstitialoma in one patient. CONCLUSION: Endoscopic submucosal resection is safe and effective in the management of tumors originating from the muscularis propria of the esophagus. Source

Aberrant expression of miR-196a has been frequently reported in different cancers including pancreatic cancer. However, its function in pancreatic cancer has not been fully elucidated. Here, we investigated the expression pattern and the biological role of miR-196a in pancreatic cancer cell lines, as well as its interaction with a metastasis-related gene, nuclear factor-kappa-B-inhibitor alpha (NFKBIA). We demonstrated that miR-196a was up-regulated in human pancreatic cancer cell lines compared with immortalized pancreatic ductal epithelial cells by means of microRNAs microarray and qRT-PCR. Furthermore, down-regulation of miR-196a in PANC-1 suppressed its proliferation and migration with an increase in G0/G1 transition and decreased expression of Cyclin D1 and CDK4/6. Meanwhile, an increased expression in E-cadherin and decreased expression in N-cadherin and Vimentin were also observed. We identified a novel miR-196a target, NFKBIA, and down-regulation of miR-196a enhanced the expression of NFKBIA protein. Luciferase assay confirmed that NFKBIA was a direct and specific target of miR-196a. Silencing NFKBIA in PANC-1 cells enhanced its proliferation and migration. Taken together, our findings indicate that miR-196a is highly expressed in pancreatic cancer cell lines, and may play a crucial role in pancreatic cancer proliferation and migration, possibly through its downstream target, NFKBIA. Thus, miR-196a may serve as a potential therapeutic target for pancreatic cancer. © 2014 Huang et al. Source
