Cardiac implantable electronic device (CIED) is commonly used to treat arrhythmias. The amount of CIED implantation has increased year by year since its first application in 1958. At the same time, the CIED infection rate also increases significantly. Although the infection rate is very low for the primary implantation, the consequences of CIED infection are serious, and it is often necessary to remove the equipment for treatment. The mortality rate in patients with CIED infections is high, and the economic burden is huge. In this paper, the epidemiology, pathogenesis and pathogen, manifestations and diagnosis, risk factors, treatment and preventive measures of CIED infection were systematically described based on the recently published guidelines and international consensus literature, so as to provide theoretical guidance for the prevention of CIED infections.

ObjectiveTo investigate the status quo of emergency resources in all township hospitals in a county of Aba Autonomous Region. MethodWe set up a uniform electronic version questionnaire between April 15th and 18th, 2015. The leaders of township hospitals filled in their information and uploaded the data including emergency medical services, human resources, medical device and technology application situation. Then, the data were statistically analyzed. ResultsFor these township hospitals, the service population was 2 206.05±846.95, the service radius was (25.5±14.3) km. The number of registered doctors per 1 000 people of resident population was 1.52, the number of registered nurses per 1 000 people of resident population was 0.47, and the number of hospital beds per 1 000 people of resident population was 1.69. The staff in all township hospitals included 74 doctors and 23 nurses. The constitution of positional titles and academic qualifications of doctors and nurses in these township hospitals was not significantly different (P>0.05). All township hospitals had a total of six ambulances, one of which was ambulance for rescue and monitoring, and the others were ordinary ambulances. The devices equipped in the ambulances and hospitals were not sufficient, and most doctors and nurses could only perform surrounding vein puncture, and debridement and suture surgery. They could not recue critically ill patients alone. ConclusionsFor these township hospitals, the service radius is too long, the number of doctors and nurses is too small, and the ability of service is insufficient. In order to meet the demand of emergency resources in ethnic areas as far as possible, we should increase investment and promote medical devices, increase the number of doctors and nurses, improve the personnel structure, and strengthen professional training.
Objective To analyze the clinical information of COVID-19 patients of Shanghai National Exhibition and Convention Center cabin hospital, and to explore the medical management strategy to provide thoughtful suggestions for other cabin hospitals and governments as valuable references. Methods The clinical data of 174 308 patients confirmed COVID-19 in Shanghai National Exhibition and Convention Center cabin hospital from April 9 to May 31, 2022 were retrospectively reviewed. There were 103 539 male and 70 769 female patients, with an average age of 41.50±15.30 years. Medical and nursing management strategy was summarized. Results Among the 174 308 patients, 71.5% (124 630 patients) were asymptomatic. The vaccination rate of patients with COVID-19 in the cabin hospital was 76.5% (133 338 patients), and the majority of none vaccinated patients were children under the age of 10 years and the elderly over the age of 60 years, the vaccination rate of whom was only 25.0% (1 322 patients) and 63.9% (13 715 patients), respectively. In addition, the proportion of mild symptom type in the patients not vaccinated was significantly higher than that in the vaccinated patients (P≤0.01). The average hospitalization time of patients in cabin hospital was 7.39±0.53 days, which was 7.01±2.12 days for patients under 60 years and 8.21±0.82 days for patients over 60 years. The hospitalization time of elderly patients was significantly longer (P≤0.01), and the hospitalization time of elderly patients at age over 60 years without vaccination was 8.94±1.71 days, which was significantly longer than the average hospitalization time and the time of elderly patients vaccinated (P≤0.01). The number of patients combined with basic diseases was 27 864 (16.0%), of which cardiovascular diseases accounted for 81.3% (22 653 patients). A total of 2 085 patients were transferred and treated in designated hospitals. Conclusion Large scale cabin hospitals are helpful to cut off the source of infection. Attention shall be paid to the sorting of admission and timely transfer to other hospital during the patients management. Most of the patients have a good prognosis after treatment. The vaccination of key population and community-based screening will be the next step of focus.
Purpose Researching the relared risk factors of diabetic retinopathy (DR) through the epidemiological investigation. Methods Basing on a population random sampling survey and screening in 6 areas and cities of Anhui,216 diabetics were screened and they were then investigated in detail by filling in forms,measuring blood pressure,ocular examination including ophthalmoscopy,and lab examination including fasting blood glucose (FBG),blood glucose 2 hours after meal,urine albumin excretion (UAE),serum triglyceride,and cholesterol. Results The resultant date revealed that the duration of diabetes,blood pressure FBG and UAE were associated significantly with DR (Plt;0.05),and serum triglyceride and cholesterol were associated not significantly with DR(Pgt;0.05). Conclusion Long duration of diabetes,hight FBG and hight blood pressure are the important risk factors of DR,and urine albumin might forebode the occurrence of DR. (中华眼底病杂志,1998,14:119-121)
Objective To study the composition, distribution, and influencing factors of acute hand injuries in daily l ife in the Beijing area by analyzing the cl inical data from patients with acute hand injuries. Methods Between April 1st 2005 to September 30th 2005, 2 575 patients with acute hand injuries in daily l ife from Beijing area were investigated by questionnaire.The epidemiological factors were analyzed, including gender, age, injury time, injury cause, accident place, injury mechanism, and location. Results The 2 575 patients injuried in daily l ife accounted for 49.2% of all. Most of them were young males, and the male to female ratio was 3.3 ∶ 1. Most of the patients were 21-30 years old. The most common accident place was resting place (43.3%), and next was outdoors (28.8%) and leisure place (20.0%). Accidental injury was the major injury cause, accounted for 51.0%, followed by injury after drinking (16.1%) and violence (15.5%). The major injury mechanism was cutting (52.23%), followed by coll ision (16.04%) and fall ing (15.18%). A total of 2 405 patients were right hander, and handedness affected the distribution of injured hands significantly. Open injuries accouonted for 70.7% of the patients, and the tissues in deep layer were involved in the injury in 54.4% of all. Conclusion Hand injury in daily l ife is a common problem, which has its own epidemiological features. More appropriate measures should be taken to decrease the incidence.
Objective To determine the incidence of and risk fact ors for retino pathy of prematurity (ROP) among preterm infants in Beijing after implementation of the ROP guidelines. Methods The preterm infants with birth weight le; 2000 g or gestational age le; 3 4 weeks who were admitted to the neonatal intensive care units in 6 hospitals in Beijing from Jan. 1, 2005 to Dec. 31, 2005 were screened. Ophthalmologic examin ations started 3-4 weeks after birth and ROP was classified by the revised Inte r national Classification. Maternal and perinatal risk factors of occurrence of R OP were analyzed. Results In the 639 infants who had been scre ened in the 6 ho spitals, ROP was detected in 69 (10.8%), in whom 23 infants (39 eyes) (3.6%) had type 1 ROP and underwent photocoagulation. The lower the birth weight and small er the gestational age was, the higher the incidence of ROP was. Logistic regres sion analysis indicated that low birth weight, apnea gt;20 seconds, anemia, hypoxic-ischemic encephalopathy and placenta abruption were the high risk factor of R O P.Conclusion In Beijing the incidence of ROP is 10.8% after i mplementation of the ROP guidelines. Low birth weight, apnea gt;20 seconds, anemia, hypoxicischem ic encephalopathy and placenta abruption were the high risk factor of ROP.
ObjectiveTo investigate the clinicopathologic and epidemiological characteristics of patients with gastric cancer at our hospital in the past six years． Methods A total of 958 patients with gastric cancer were selected from January 2004 to December 2009 and clinicopathologic characteristics such as basic data, pathological type, tumor location, and TNM stage were retrospectively analyzed. ResultsOf the 958 patients，697 cases (72.8%) were male and 261 cases (27.2%) were female, and the age ranged from 26 to 91 years old (mean 62.6 years old). The occurrence rate of gastric cancer was higher in the patients of 46-65 years old (49.4%, 473/958) than that in the patients of ≥66 years old (42.3%, 405/958) and ≤45 years old (8.3%, 80/958). Regarding pathologic type, the majority of advanced gastric cancers (70.1%) were Borrmann Ⅱ, the adenocarcinoma and signetring cell carcinoma accounted for 82.3% and 7.8%, respectively. The cancer of gastric cardia accounted for 53.0%. Stagestratified analysis revealed that the majority of gastric cancers (47.4%) were stage Ⅲ. Conclusion①A prevalence of gastric cancer is found in middle, elderly male patients. Poorly differentiated adenocarcinoma in cardia is prominent. ②Patients with high malignant ganstrie cancer are younger. ③The majority of patients who underwent the surgical treatments have advanced or metastatic tumor, therefore it is necessary to improve the early diagnosis of gastric cancer.
