Method Intravenous serum levels of VEGF and tumor markers were assayed by ELISA in 92 patients including 64 lung cancer from January 2008 to August 2009. Results The difference in serum levels of VEGF between the 64 patients with lung cancer [(255.72±566.0) pg/mL] and 28 health adult [(299.46±795.8) pg/mL] was not significant (Pgt;0.05). The level of VEGF in 43 patients with middle and late lung cancer [(125.07±68.2) pg/mL] was significantly higher than that in the 12 patients with early lung cancer [(196.00±260.60) pg/mL] (Plt;0.05). There were statistical significance in expression of serum CEA and CYFRA21-1 on diagnosis in 26 patients having lung cancer with early metastasis pleural fluid (Plt;0.05). Conclusion Combined diagnostic of serum VEGF and tumor markers can assess the state of an illness and clinical stage, and the serum levels of serum VEGF,CEA and CYFRA21-1 may be a good predictor for lung cancer with early metastasis pleural fluid.
Objective To explore the effects of SU5416，a vascular endothelial growth factor receptor (VEGFR) inhibitor，on inflammation in mice with bleomycin-induced pulmonary fibrosis.Methods C57BL/6 mice were randomly divided into four groups，ie.a control group，a bleomycin-induced pulmonary fibrosis (BPF) group,early intervention with SU5416 group (days 1-14，SE)，and delayed intervention with SU5416group (days 15-28，SD).Bleomycin (10 mg/kg) was instilled into the trachea of the mice to induce pulmonary fibrosis.After the instillation，SU5416 (50 mg/kg) was injected into the peritoneal cavities of the mice twice a week.The mice treated with bleomycin alone or with bleomycin followed by SU5416 were sacrificed on the day 14 and day 28 after the instillation of bleomycin.Lung tissues were taken and processed for determination of hydroxyl proline content.Bronchoalveolar lavage fluid (BALF) was collected for total and differential cell counts and measurements of lactic dehydrogenase (LDH) levels.Results It was found that the hydroxyl proline contents，the number of macrophages，and the LDH contents from the mice treated with bleomycin alone on day 14 were greatly increased.However，only the hydroxyl proline showed a significant increase in the mice treated with bleomycin alone on day 28.The number of macrophages，LDH contents，and hydroxyl proline contents were greatly reduced in the mice treated with bleomycin and early administration of SU5416 on day 14 when compared with those treated with bleomycin alone.But there were no significant differences in the above parameters of the mice treated with bleomycin and delayed administration of SU5416 on day 14.Conclusion This study indicates that early intervention by SU5416 might attenuate the fibrosis through inhibiting early inflammation in animal model of pulmonary fibrosis induced by bleomycin.
ObjectiveTo know the situation of nosocomial infection in 2014 in a western region hospital, in order to provide a scientific basis for hospital infection control and management. MethodWe selected the patients on August 14th in 2014 during the time from 00:00 to 24:00 as our study subjects. Bedside investigation and medical records investigation were combined to study the cross-sectional survey of nosocomial infection. We completed the questionnaire, and used statistical methods to count related data about nosocomial infections and community-acquired infections. ResultsA total of 1 908 patients were investigated. The nosocomial infection prevalence rate was 4.45%, and the community-acquired infection prevalence rate was 29.09%. The highest prevalence of nosocomial infection department was the Intensive Care Unit (38.10%); the top three surgical systems were Thoracic Surgery (18.67%), General Surgery (16.67%), and Neurosurgery (10.53%), and the top three medical systems were Endocrinology (11.11%), Neurology (6.67%), and Infectious Diseases Department (5.88%). The top three community-acquired infections occurred in Pediatrics Department (non-neonatal group) (95.37%), Burn surgery (92.31%), and Respiratory Medicine (86.46%). The main infection site for both nosocomial and community-acquired infection was lower respiratory tract (58.24%). Pathogens were mainly Escherichia coli, Klebsiella pneumoniae, Acinetobacter baumannii, Staphylococcus aureus, and Pseudomonas aeruginosa. Hospital and community-acquired infection bacterial spectrum were consistent. And the rate of antibiotics use was 40.82%, in which 126 patients used for prevention (6.60%), and 599 patients used for treatment (31.39%). For patients using the drugs for treatment, bacterial culture submission rate was 80.71%, and the positive rate was 43.78%. ConclusionsThe prevalence of nosocomial infection is reliable, which provides a data support for nosocomial infection prevention and control.
Objective To understand the current rate of nosocomial infection and its changing trend in a grade A comprehensive hospital in 10 years, and to provide scientific basis for the monitoring, control and management of nosocomial infection. Methods Using the method of cross-sectional survey, the inpatients in Mianyang Central Hospital from 2011 to 2020 were selected for bedside survey, and the questionnaire was filled in after review of medical records. The data of cross-sectional survey of nosocomial infection were collected, and the infection-related data of nosocomial and community-acquired infection of patients in each department were statistically analyzed. Results A total of 19 595 cases were investigated. The prevalence rate of nosocomial infection was 3.79%, and the the case prevalence rate of nosocomial infection was 4.04%. The prevalence of community-acquired infection was 33.44%, and the case prevalence rate of community-acquired infection was 35.30%. The departments with higher prevalence rate in nosocomial infection were intensive care unit, neurosurgery, cardiothoracic surgery and hematology. The departments with high prevalence rate in the community-acquired infection were burn department, pediatrics department, neonatology department, respiratory medicine department and pediatric intensive care unit. The most common site of nosocomial infection was lower respiratory tract infection, followed by upper respiratory tract sensation, urinary tract, abdominal tissue and blood. The main pathogens of nosocomial infections were Escherichia coli, Klebsiella pneumoniae, Acinetobacter baumannii, Staphylococcus aureus, and Pseudomonas aeruginosa. The utilization rate of antibacterial drugs was 42.93%. There was a downward trend in prophylactic drug use, mainly one drug combination, and the proportion of combination drug decreased.Conclusion Through the investigation, it can be seen that the key points of nosocomial infection management and prevention and control should be lower respiratory tract infection, postoperative surgical infection, multi-drug resistant bacteria management and rational use of antibiotics.
Objective To understand the situation of commonly-used drugs, medical device and their storages in rural households among model well-off township hospitals in eastern, central and western China, and to provide the basis for the guidance of reasonably using and scientifically storing drugs. Methods The methods of combining simple random sampling and cluster sampling were used to investigate and analyze the situation of commonly-used drugs, medical device and their storages in 162 households from three well-off township hospitals in Shanghai, Zhejiang, and Sichuan provinces, respectively. Results The storage rates of commonly-used drugs of rural households in well-off towns were cold medicine (72.2%), wound paste (51.9%), cooling oil (39.5%), essential balm (36.4%), antihypertensive (27.8%), iodine tincture (14.2%), anti-diabetic drugs (13.0%) and other drugs (17.3%). The storage rates of medical devices were thermometer (50.0%), cotton swab (47.5%), sphygmomanometer (9.3%), injector (1.2%) and other devices (22.2%). A total of 66% of respondent families stored drugs and medical devices in a fixed drawer. Only 3.1% families stored drugs and medical devices in the special portable medical kit. Conclusion Rural families have a higher rate of household drugs among model well-off township hospitals in eastern, central and western China, and most drugs are OTC drugs. The storage rates of medical devices are not high. Many rural family-owned medical devices are linked with special chronic diseases in the family. A lot of rural families place drugs and medical devices randomly. There are many security risks, and it may affect the rational utilization of drugs.
Objective To understand the demands on portable medicine kit of rural residents in well-off township hospitals, and to provide the basis for scientifically designing portable medicine kit for rural residents. Methods The methods of combining simple random sampling and cluster sampling were used to investigate and analyze the demands on portable medicine kit for 162 households from three well-off township hospitals in Shanghai, Zhejiang, and Sichuan province, respectively. Results The demand rate of 162 rural households on portable medicine kit was 75.3% (122/162). The main drugs that demanders expected in the portable medicine kit were cold medicine (86.1%), wound paste (82.0%), cooling oil (61.5%), essential balm (54.9%) and antihypertensive (34.4%); and the main medical devices that demanders expected were thermometer (82%), cotton swab (73%) and sphygmomanometer (32.8%). The sizes of portable medicine kit that demanders expected were 23.7±8.5 cm in length, 17.1±6.4 cm in width, and 14.1±6.5 cm in height. The main function characteristics of portable medicine kit that demanders expected were applicability (74.6%), safety (60.7%), light weight (68.0%), economics (60.7%), and waterproof (46.7%). A total of 72.1% of demanders expected the price of less than 15 yuan, and 91.8% expected kit made of hard materials as plastic as the first choice. Conclusion The demand rate of rural residents on portable medicine kit is higher in well-off township hospital. The design and production of portable medicine kit should fully meet the demands of rural residents. Only when sufficiant respect for the market demand is paid, can the promotion and application of portable kits will be ensured.
