Objective:To analyze the advantages of the pressure-regulated volume control (PRVC) mode compared with the traditional continuous mandatory ventilation (CMV) mode about mechanical ventilation efficiency of ventilator.Methods: For the mechanical ventilation situations, the parameters of PRVC mode, V-CMV mode and P-CMV mode under same detecting conditions were tested by using gas analyzer, which based on the ventilation principle of PRVC mode. And then the differences between PRVC mode and CMV modes were analyzed. Results: PRVC mode can supply the almost same tidal volume, and provide lower pressure and higher compliance compare with the V–CMV mode under the same conditions. On the other hand, PRVC mode can supply more tidal volume and slightly higher compliance compare with the P–CMV mode under the same pressure.Conclusion: PRVC mode has combined with the advantages of CMV mode, and it can make sure the target tidal volume, at the same time, reduce the pressure of airway, and improve the compliance for circuit. It also can make the mechanical ventilation to got more efficiency and more safety.

Objective To evaluate the precipitating factor,mortality,complications of myasthenia gravis crisis and risk factors of prolonged intubation.Methods Totally 82 case records of patients who had been adimitted for having 87 episodes of myasthenia crisis over a period of 15 years from January 1985 to February 2000 and their age, gender, precipitating factors, complications of intubation, and prolonged intubation factors were retrospectively reviewed. Results In 75% of myasthenic crisis patients having precipitating factors, infection was the most often served as the precipitating factors, and then the wound, fatigue, manopause and delivery came the next, 24% of precipitating factors were related to medication. Nine were identified with independent predictors of prolonged intubation. Among the 82 myasthenia crisis patients, 12 died, with a mortality of 14%.Conclusion The prevention and treatment for intubation complications may be the best way for further shortening intubation time and reducing the mortality.

Objective: To research and establish an analysis model for chemical drug standards to provide the reference for the standard exploration jobs. Methods:The standard variation was studied by comparing and analyzing every version standard for the same drug to look for the change rule. Results:The standard items of the drug had some change rules in indicator numbers, testing methods and limits according to the order of issue time. The standard development trends could be described by making specific indicators and drawing evolution figures of the items. Conclusion:By the standard analysis model, the same item of the same drug can be compared to provide the reference for data collecting of experts. Meanwhile, formulate standard can be calculated to provide the reference for the standard improvement without drug standards.

Objective To understand the characteristics of population distribution,risk factors and risk links of occupational exposure among health care workers(HCWs)in a hospital.Methods Occupational exposure among HCWs between January 2011 and June 2014 were monitored,data about occupational categories of HCWs,expo-sure locations,exposure links and exposure modes were analyzed statistically.Results Among 286 occupational ex-posure cases,the female and male HCWs accounted for 22.03% (n=63)and 77.97% (n=223)respectively;the incidence of occupational exposure in 2011 ,2012,2013 and January-June of 2014 was 38.81 %(n=111),26.22% (n=75),23.43% (n=67)and 11 .54% (n=33)respectively;occupational exposure of junior nurses,doctors,nurs-ing attendants,technicians,senior nurses and cleaners was 31 .97%,19.90%,15.79%,7.64%,4.17%,and 2.84% respectively;exposure mainly occurred at the time of sorting waste,withdrawing or changing needles,dis-carding sharps into sharps containers,surgical suturing or instruments passing,and puncturing (including drawing blood),the constituent ratio was 22.38%,19.58%,14.34%,12.94% and 11 .19%,respectively;the main loca-tions where exposure occurred were wards,operating rooms and injection (treatment)rooms,the constituent ratio was 51 .40%,19.58% and 11 .54% respectively.Conclusion Hospital should establish comprehensive occupational exposure monitoring and risk management system,strengthen standard prevention,enhance the training about occu-pational exposure among high-risk population,and monitor and intervene on risk factors and links,so as to reduce the incidence of HCWs’occupational exposure.

[Summary] During the past 10 years, the prevalence of obesity and type 2 diabetes mellitus ( T2DM) worldwide has increased greatly.Western dietary pattern is often regarded as the primary causes of the metabolic diseases like obesity and T2DM.A number of other diets have been shown to be effective for the management of obesity and T2DM, such as the Mediterranean diet, the vegetarian diet, the low-calorie diet and the macrobiotic diet.In addition, recent studies have suggested that an imbalance of the intestinal microbiota may be involved in the development of obesity and T2DM.The main regulator of the intestinal microbiota is diet, and the composition of microbiota is impacted by long time diet pattern.This article reviews the recent advance in the influence of different diet patterns on human metabolism and gut microbiota.
