Chinese Journal of cardiovascular Rehabilitation Medicine 2015;24(4):442-444
Objective:To explore clinical significance of prehospital first aid in treatment of patients with cardiopul-monary arrest caused by electrical shock.Methods:A total of 85 patients with cardiopulmonary arrest caused by e-lectrical shock,who hospitalized in our community health service center from Jul 2002 to Feb 2014,were selected. Influence of different factors of prehospital first aid on success rate of recovery and survival rate were explored.Re-sults:After prehospital first aid,heart beat and respiration recovered in 21 cases (24.7%)and 13 patients (15.3%) survived and discharged in 85 subjects.Success rate of recovery and survival rate on discharge in patients with age ≥60 years and high voltage wound were lower,but without significant difference compared with those of <60 years and low voltage wound (P >0.05);for the time from electric shock to cardiopulmonary resuscitation,success rate of recovery and survival rate on discharge were the highest in <5min patients;compared with first aid time<5min, there were significant reductions in success rate of recovery (58.33% vs.31.58% vs.8.00% vs.0%)and survival rate after discharge (58.33% vs.15.79% vs.0% vs.0%)in 5~11min,11~16min,>16min,P <0.05 or <0.01. Conclusion:Early prehospital first aids,such as cardiopulmonary resuscitation etc,can significantly improve progno-sis in patients with cardiopulmonary arrest caused by electrical shock.

An improving method, named direction-coding, is presented in this paper for plotting isodose curves in brachytherapy treatment planning. It is not necessary to find solutions of the intersection point of two lines and distance between two points. All possible curves can be searched with the simplified algorithm. The method is well applied in brachytherapy treatment planning.

Objective To investigate the relationship between the epidemiology of chronic rhinitis and atmospheric environmental factors in Wuhan. Methods A total of 3 371 patients with chronic rhinitis in Wuhan seventh hospital from January 2017 to January 2020 were enrolled. The incidence of chronic rhinitis in different years and seasons was compared. Then the influence of atmospheric environmental factors such as air pollution index (API), fine particulate matter (PM2.5), inhalable particulate matter (PM10), nitrogen dioxide (NO2), sulfur dioxide (SO2), diurnal patterns of relative humidity, wind speed, air temperature, air pressure wind speed and temperature range on occurrence of chronic rhinitis was analyzed. Results The incidence of chronic rhinitis in Wuhan showed an annual decreasing trend from 2017 to 2020, so the incidence rate was the highest in 2017 (38.83%, 1309/3371) and was the lowest in 2020 (28.98%, 977/3371). In terms of different seasons, the incidence rate was the highest in winter (33.67%, 1135/3371), and was the lowest in summer (16.11%, 543/3371). The main factors affecting the incidence of chronic rhinitis were API, PM2.5, and PM10 in spring, which were NO2, SO2, and daily average relative humidity in summer, those were API, PM2.5, PM10, NO2, and SO2 in autumn, and were API, PM2.5, PM10, NO2, SO2, and daily range of air temperature in winter. The lag response of patients with chronic rhinitis to atmospheric environmental factors was 2-5 days in spring, 1-6 days in summer, 0-5 days in autumn and 3-6 days in winter. Patients with chronic rhinitis have the fastest response to API and PM2.5 in spring, the fastest response to API in summer, and the fastest response to API and PM2.5 in autumn, respectively. Conclusion The incidence of chronic rhinitis in Wuhan is decreasing year by year, and the incidence is related to environmental and meteorological factors, and the disease onset has the characteristics of lag due to seasonal factors.

Antibiotic susceptibility tests were conducted by agar dilution or broth dilution methods recommended by Clinical Laboratory Standards Institute (CLSI). WHONET 5.6 was used to analyze data.Results:During the study period, 11 013 bacterial strains were collected from 51 hospitals, of which 2 782 (25.3%) were Gram-positive bacteria and 8 231 (74.7%) were Gram-negative bacteria.

The prevalence of methicillin-resistant Staphylococcus aureus (MRSA) and methicillin-resistant coagulase-negative Staphylococcus aureus were 25.3% and 76.8%, respectively. No glycopeptide- and daptomycin-resistant Staphylococci was detected; more than 95.0% of Staphylococcus aureus were sensitive to ceftobiprole. No vancomycin-resistant Enterococci strains were detected. The rates of extended spectrum B-lactamase (ESBL)-producing isolated in Escherichia coli, Klebsiella pneumoniae and Proteus mirabilis were 49.6%, 25.5% and 39.0%, respectively. The prevalence rates of carbapenem-resistance in Escherichia coli and Klebsiella pneumoniae were 2.2% and 15.8%, respectively; 7.9% of carbapenem-resistant Klebsiella pneumoniae was resistant to ceftazidime/avibactam combination. Ceftobiprole demonstrated excellent activity against non-ESBL-producing Escherichia coli and Klebsiella pneumoniae. Aztreonam/avibactam was highly active against carbapenem-resistant Escherichia coli and Klebsiella pneumoniae. The prevalence rate of carbapenem-resistance in Acinetobacter baumannii was 60.0%, while polymyxin and tigecycline showed good activity against Acinetobacter baumannii (5.5% and 4.5%). The prevalence of carbapenem-resistance in Pseudomonas aeruginosa was 18.9%. Conclusions:The BRICS surveillance results in 2021 shows that the main pathogens of blood stream infection in China are gram-negative bacteria, in which Escherichia coli is the most common. The MRSA incidence shows a further decreasing trend in China and the overall prevalence of vancomycin-resistant Enterococci is low. The prevalence of Carbapenem-resistant Klebsiella pneumoniae is still on a high level, but the trend is downwards.
