Objective To explore the effect of prospective nursing on preventing constipation for patients with acute myocardial infarction(AMI). Methods 43 AMI patients during July 2008 and June 2010 in our hospital were classified as the observation group, besides the nursing routine of the acute myocardial infarction plus routine therapy to prevent constipation, prospective nursing was implemented.Through the retrospective analysis of medical record, 41 of AMI in our hospital during March 2006 and June 2008 were classified as the control group, they were given the nursing routine of the acute myocardial infarction plus routine therapy to prevent constipation and the nursing intervention after occurrence of constipation. The defecation condition was assessed for the two groups of patients on admission and the defecation and mortality rate was compared on the eighth day of hospitalization. Results There was significant difference in constipation and mortality rate between the two groups of patients during hospitalization. Conclusions The prospective nursing for AMI patients to prevent constipation can obviously reduce the incidence of constipation, thus to avoid serious complications caused by constipation and reduce mortality.

Objective:To discuss the relationship between blood-lipid change and acute cerebrovascular disease (ACVD) and tocompare the blood-lipid levels in the patients with cerebral hemorrhage (CH group) with those in the patients with cerebralinfarction (CI group). Methods:The blood-lipid levels in 300 patients with ACVD (ACVD group) and 100 patients withother system disease (control group) were tested with automatic biochemistry analysor and compared between the twogroups. Results:There were significant differences between ACVD group and control group as well as between CH group andCI group. Conclusion:Although there were blood-lipid metabolic disturbances in both CH and CI patients, their degrees weresignificantly different, which should be closely observed and controlled in clinic.

Objective To explore value of detecting fetal thymus size with the thymic-thoracic ratio (TT-ratio).Methods Prenatal ultrasonography examinations were performed on totally 317 normal singleton healthy pregnancies from 18 to 39 gestational weeks.The normal thymus of fetus were observed on the three-vessel-trachea (3VT) view.The anteroposterior diameter of the thymus (T1) was measured between the anterior border of the aortic arch and posterior border of sternum.The intrathoracic mediastinal diameter (T2) was measured between the anterior border of thoracic vertebral body and posterior border of sternum.The TT-ratio was then calculated as the ratio of T1 to T2.Scatter plot between TT-ratio and gestational age was drawn.And the Spearman regression analysis was performed.Results The thymus of fetus was shown as an irregular homogenous structure in the anterior mediastinum on the 3VT view.The mean TT-ratio was 0.45± 0.03.There was no correlation between TT-ratio and gestation (rs =0.06,P=0.29).Conclusion Prenatal ultrasound can display the thymus obviously.TT-ratio could be applied to assess the fetal thymus size,which can provides clinical basis for the detection of absent or hypoplastic thymus in fetus.

OBJECTIVETo investigate the frequency of p16 and p15 gene methylation in multiple myeloma (MM), and its relationship with bone marrow cell apoptosis and clinical outcome.

METHODSTwenty-two patients with MM were studied to detect p16 and p15 gene methylation. Methylation-specific polymerase chain reaction (MSP) was used to detect gene methylation, and terminal transferase-mediated dUTP nick end-labeling (TUNEL) was used to detect cell apoptosis.

RESULTSp16 and/or p15 gene methylatoin was detected in 10 of 22 patients (45.4%). There were 3 patients with p16 gene methylation, 9 patients with p15 gene methylation, and 2 patients with both genes methylation. The incidence of methylation of p15 gene was higher than that of p16 gene (P < 0.05). The patients with p16 and/or p15 gene methylation had a delayed cell apoptosis, poor response to chemotherapy, and a short over-all survival (OS).

CONCLUSIONThe methylation of p16 and/or p15 gene plays a key role in MM apoptosis pathogenesis. The patients with both p16 and p15 gene methylation had a poor prognosis.

Objective To make clear the arsenic distribution in drinking water sources in Hubei Province, make provincial distribution map of high-arsenic water and provide scientific basis for formulating refined measures to prevent and control arsenic poisoning of drinking water type in Hubei Province. Methods In 103 counties of Hubei Province, residents were sampled according to different water supplies (centralized water supply, small centralized water supply in rural areas and decentralized water supply). One water sample was collected from source water and tap water in centralized water supply system and at least 3 samples were collected from decentralized water supply system in a village. Water iodine content was tested using atomic fluorescence spectrometry and a distribution map of high-arsenic water at county level was drawn using ArcGIS 10.2. Results Totally 38 292 water samples were collected. The water-arsenic-concentration median was less than 1.00 μg/L. The high-arsenic water detection rate in urban centralized water supply was 3.7%(80/2 176);which were all 0.1%(4/4 304,30/31 812) in small centralized water supply in rural areas and decentralized water supply. The high-arsenic water sources from centralized water supplies were distributed centrally in the south, the central and the east of Hubei Province and those from dispersed water supplies were distributed dispersedly in the south, the central and the east of Hubei Province.Conclusions There are still some dispersed water supplies with very high arsenic concentration in Hubei Province, which should be included to change the water area as soon as possible. Moreover, high arsenic water samples are found from centralized water supplies, which means the water treatment process should be upgraded or water resources should be changed.

Objective To make clear the fluorine content distribution in drinking water of residents in Hubei Province,draw a provincial distribution map of high-fluorine water and provide scientific basis for formulating refined prevention and control measures of drinking water type fluorosis in Hubei Province.Methods In 116 counties of Hubei Province,including development zones,scenic zones and farmlands,drinking water of residents was sampled according to different water supplies (centralized water supply,small centralized water supply in rual areas and decentralized water supply) from 2013 to 2015.For a centralized water supply,one sample was collected from the source water and the tap water each and at least 3 samples were collected for decentralized water supply in a village.Selective electrode method was used to detect the water fluorine content and ArcGIS 10.2 was used to draw distribution map of high-fluorine water at county level.Results A total of 38 284 water samples were collected,the median of fluorine content was 0.21 mg/L.The highest detective rate of all types of water supply with high fluorine content was pressure water well (64/100,64.0％) and high-fluorine water sample was not found in the reservoir.The high-fluorine water sources from centralized water supplies were distributed dispersedly in the north-west and the east of Hubei Province and those from decentralized water supplies were distributed dispersedly in the middle-north and the east of Hubei Province.Conclusions Fluorine concentration in drinking water is generally low.However,there are still some high-fluorine water supplies which should be reported to Hubei Provincial Water Resources Department as soon as possible.Moreover,there is a phenomenon of fluorine rebounce in the water reduction project,and managements of those projects should be strengthened.
