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 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 observe influence of salmeterol xinafoate and fluticasone propionate powder applied in asthmatic exacerbated period on relieving efficacy of a fast-acting beta2-agonist.Methods Eighty-nine children with asthma in exacerbated period were randomly assigned into two groups.Thirty-nine cases in treatment group inhaled salmeterol xinafoate and fluticasone propionate powder, compared with 50 cases in control group treated with budesonide aerosol. Two groups were all given Bricanyl aerolised inhalation in same way at meanwhile.Results The improvement of peak expinatory flow in two groups was evident. The disappearing time of main symptoms and signs, the duration of staying in hospital of two groups were no difference (all P

Objective To study the effects of Traditional Chinese Medicine(TCM)therapy on shoulder hand syndrome(SHS).Methods 50 patients with SHS were divided into rehabilitation group and control group.The patients in rehabilitation group accepted physiotherapy and TCM therapy,which include marinate in traditional herb,pulsed electromagnetic therapy,massage and stimulate point.The patients in control group accepted physiotherapy only.They were evaluated after 1 month.Results The cured rate and the improved rate in rehabilitation group were higher than those in control group(P<0.05).Conclusion The TCM therapy is effective on SHS.

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.

Objective To investigate the expression of serum vascular endothelial growth factor (VEGF) in local advanced esophageal carcinoma patients,and to explore the relationship between its change rule and the recent curative effect and significance.Methods The serum levels of VEGF in 46 patients with local advanced esophageal carcinoma were detected by ELISA before and after concurrent chemoradiotherapy,the serum levels of VEGF in 46 healthy people were detected at the same time.Results The serum VEGF levels of local advanced esophageal carcinoma patients before treatment and health control group were (264.66±62.11) ng/L and (101.96±39.53) ng/L,and the difference was statistically significant (t =23.367,P =0.000).After treatment,the serum VEGF level of patients with esophageal cancer was decreased to (127.50±49.07) ng/L (t =19.086,P =0.000).After the treatment,the serum VEGF levels of complete remission (CR) and partial remission (PR) patients were decreased [(94.03±38.86) ng/L vs (248.79±47.84) ng/L,(117.06±20.68) ng/L vs (295.26±67.20) ng/L,both P =0.000],the level of the stable disease (SD) patients was decreased,too [(235.63±26.05) ng/L vs (385.67±26.50) ng/L,P =0.017].Conclusions The recent curative effects of docetaxel and nedaplatin chemotherapy combined with intensity-modulated radiotherapy for the local advanced esophageal carcinoma patients are significant.The levels of serum VEGF before and after treatment can be used as an important index to judge the treatment effect.

Purpose To investigate the correlation between BRAF V600E mutation and clinicopathologic parameters in bilateral welldifferentiated thyroid carcinoma.Method Collected 80 patients with papillary thyoid carcinoma (PTC) (67 patients with classical type,8 patients with follicular variant,3 patients with oncocytic variant,2 patients with tall cell variant),5 patients with follicular carcinoma and 30 normal tissues near the tumor,BRAF V600E mutation was detected via polymerase chain reaction.Result The presence of BRAF V600E mutation was found in 52 patients with PTC (65.0％),the mutation was not in the 5 patients with ollicular carcinoma as well as in the 30 normal tissues near the tumor.The BRAF V600E mutation was positively correlated with age,capsule invasion,lymph node metastasis,tumor clinical stage.In the histological variant of PTC,the BRAF V600E mutation rate of classical type and tall cell variant is very high (70.1％,100.0％),but the BRAF V600E mutation rate of follicular variant is very low (33.3％).Conclusion The BRAF V600E mutation rates are different in different age groups.The BRAF V600E mutation was positively correlated with capsule invasion,lymph node metastasis,tumor clinical stage.The BRAF V600E mutation rate of classical type and tall cell variant is very higher than follicular variant.
