Objective To summarize experiences in the perioperative management for combined aortic and mitral valve replacement. Methods One hundred and twenty patients undergoing double valves replacement(DVR) within 10 years were studied. Ameliorate patients' cardiac function before operation. Median sternotomy was performed. The inter-atrial sulcus approach or the right atrial septal approach was chosen, the posterior mitral leaflet and subvalvular apparatus were preserved as much as possible, and DeVega's or Kay's valvuloplasty was performed for moderate and severe tricuspid regurgitation. According to the patient's cardiac function and general condition, active medication with vasomotor drugs, and diuretics as well as intensive postoperative care were administered in the ICU. Results Seven patients died in the perioperative period (in 30 days), and the mortality rate was 5.8%. Early postoperative complications occurred in 22 cases (18%). Conclusion Comprehensive perioperative management could reduce both perioperative mortality and postoperative complications.

Objective To explore the diagnosis and treatment efficacy of bronchobiliary fistula due to hepatic cystic echinococcosis.Methods A retrospective evaluation of 39 patients with BBF was performed during 1992 to 2012.We divided the 39 patients into group A treated before 2001 and group B after 2002.A retrospective analysis was made.Results There were three deaths among the 39 BBF patients due to hepatic hydatid disease.The cause of death was septic shock due to severe infection.There were no statistical differences in the basic factors,age (t =0.84,P =0.554),gender (P =1.0),and sputum volume (t =0.98,P =0.703),hydatid diameter (t =1.11,P =0.406),operation time,chest infection (P =1.0),mortality (P =0.235) between the two groups (P ＞ 0.05).While postoperative length of stay(t =7.64,P =0.000),postoperative complications of residual cavity (P =0.001),length of tube drainage(t =6.747,P =0.01),recurrence of bronchial fistula (P =0.022),pleural dissemination (P =0.018),reoperation rate (P =0.049) were all in favour of group B (P ＜ 0.05).Conclusions Surgery is the choice of therapy for BBF due to hepatic hydatid disease,and one-stage procedure is expected to achieve the best outcomes.

Background and purpose:Five-year survival rate of post-operation patients with non-small cell lung cancer(NSCLC)is less than 40%.Treatments after recurrence are difficult.Our study aimed to evaluate the efficacy of pemetrexed on postoperative recurrence of NSCLC.Methods:From Jan.2006 to Sep.2008,40 NSCLC with postoperative recurrence were observed.All patients had received pemetrexed(ALIMTA)500 mg/m2 or carboplatin eonbined.Results:Among the 40 patients,partial response in 10 patients(25.00%),stable disease in 19 patients(47.50%),progressive disease in 11 patients(27.50%).The total response rate was 25.00%and clinical benefit control rate was 72.50%.Pemetrexed had significantly better disease control rate in female than in male (9 1.30% vs 47.06%,P=0.034),in adenocarcinoma patients than in non-adenocarcinoma's(87.10% vs 22.22%,P=0.001).Median overall survival time(MST)was 10.70 months.Progression-free survival time(PFS)was 5.18 months.Adenocarcinoma patients had longer PFS than non-adenocarcinoma patients.Conclusion:Pemetrexed demonstrates significant antitumor activity and good tolerance in these patients.

Objective To investigate the clinical application of MR hydrography (MRH) in diagnosing alveolar echinococcosis (AE). Methods Thirty-four patients with suspected alveolar echinococcosis were examined using MRH in addition to conventional magnetic resonance imaging(cMRI).Thirty-two of the 34 patinets had surgery and the pathological diagnoses were alveolar echinococcosis.Results Among 128 lesions in these 32 patients found at surgery,cMRI examination found 68 lesions and MRH found 108 lesions.The sensitivity of cMRI examination was (53.13 ±0.04) %,the specificity was (92.59 ± 0.05) %,concordance rate was (60.00 ± 0.03) %.The sensitivity of MRH examination was (84.38 ± 0.03) %,the specificity was (81.48 ± 0.08) %,concordance rate was (83.87 ± 0.03) %.Comparing concordance rate of cMRI examination and MRH,significant difference was found (U = 5.44,P < 0.01).Conclusion MRH technique can raise the sensitivity and concordance rote for diagnosing AE. This technique should be employed in the evaluation of patients suspected of AE.

Background Pupillary light reflex has been widely used in the diagnosis and evaluation of visual system and nervous system diseases.However,in animal experiments,functional evaluation of the visual system and nervous system needs more advanced technology and are affected by many factors.Objective This study was to explore the use of the dynamic pupillometer in evaluating pupillary light reflex and to discuss the influence of brightness of stimulate on relevant curve parameters in C57BL/6 mouse.Methods Ten healthy SPF male C57BL/6 mice were collected in this experiment.White light of five luminance levels (2,8,32,128,256 cd/m2) was used to stimulate the mice following a 2-hour dark adaptation.The stimulation was given at the 60-second intervals,for a duration of 100 ms at every stimulation.An infrared camera and video capture card were used to capture digital images during the measuring process in a scotopic environment,at a speed of 60 frames per second.Measuring outcome was saved in the*.AVI format.A software that was developed by our group was used to determine pupil diameter and output pupillary light reflex curve offline.Pupil initial diameter (R1),constriction amplitude (CA),constriction velocity (CV),latency (T1),time for maximum velocity (T2),time for maximum constriction (T3),time for maximun con-striction to 10.1％ R1 re-dilation (RT)and re-dilation velocity (RV)were assessed,and the correlations between luminosity and measuring parameters were analyzed using the Spearman rank correlation.The use of animals followed the Regulations for thd Administration of Affairs Concerning Experimental Animals by State Science and Technology Commission.Results R1 values showed no statistically significant difference among the 5 different luminosity groups(F=1.117,P=0.361).A positive linear correlation was found between stimulating luminosity and CA(r=0.508,P＜ 0.01),but negative correlations were seen between stimulating luminosity and CV or RV (r=-0.625,-0.609,P＜0.01).T1 and T2 values in the 5 different luminosity groups were not statistically significant (F =0.202,P =0.936 ; F =1.584,P =0.195).The different levels of stimulating luminosity showed positive linear correlations with T3 and RT values (r =0.791,0.609,P＜ 0.01).Conclusions The dynamic pupillometer can quantitatively measure the pupillary light reflex of C57BL/6 mice.The pupillary light reflex dynamic curve parameters of mouse were affected by stimulus luminosity levels.These outcomes offer a basis for the application of the dynamic pupillometer system for measuring pupillary light reflex in animal models.

Objective: To discuss the application principle in tuina manipulation for lumbar intervertebral disc herniation (LIDH) in Chinese literatures published in recent 30 years. Methods: The three major Chinese databases, Wanfang Academic Journal Full-text Database (Wanfang), Chongqing VIP Database (CQVIP) and China National Knowledge Infrastructure (CNKI), were searched to collect the studies of tuina manipulations in treatment of LIDH published in recent 30 years. Clustering analysis was applied to analyze the top 20 tuina manipulations for LIDH. Results: The top 20 most frequently used manipulations for LIDH were Gun-rolling, Rou-kneading, Dian-digital pressing, oblique Ban-pulling, An-pressing, Tanbo-plucking, Bashen-pulling and extending, horizontal Tui-pushing, Na-grasping, Anrou-pressing and kneading, Dou-shaking, Yao-rocking, Ca-scrubbing, Pai-patting, post-extension Ban-pulling, Mo-rubbing, Zhen-vibrating, Nie-pinching, fist-back Ji-tapping, and dorsal Shen-extending methods. The involved manipulations can be divided into two categories by the treated body areas. One category is applied to the soft tissues, including Gun-rolling, Rou-kneading, Dian-digital pressing, An-pressing, Tanbo-plucking, horizontal Tui-pushing, Na-grasping, Anrou-pressing and kneading, Ca-scrubbing, Pai-patting, Mo-rubbing, Zhen-vibrating, Nie-pinching, and fist-back Ji-tapping methods. The other category is applied to bones and joints, including oblique Ban-pulling, Bashen-pulling and extending, Dou-shaking, Yao-rocking, post-extension Ban-pulling, and dorsal Shen-extending methods. Conclusion: Based on the treated body area, the tuina manipulations applied to treat LIDH are predominated by the ones performed on soft tissues, assisted by those on bones and joints. From the way of force exertion, the involved manipulations are majorly the swinging methods, followed by squeezing and pressing ones. The manipulations applied to bones and joints are predominated by the Ban-pulling ones, followed by the Bashen-pulling and extending ones.

Objective To investigate the independent factors influencing the efficacy of pre-hospital CPR effect. Method The data base with 1376 cases was set up with EpiData software by means of questionnaires and the information was provided by the survivals from cardiopulmonary arrest( CA)saved with cardiopulmonary resuscitation(CPR), and the data were analyzed with SPSS 13.0 software to carry out binary logistic regression. Through single factor analysis, the factors with emerged statistical significance were chosen as variances. Results With regard to the restoration of spontaneous circulation(ROSC), the rescue did by the first witness was the protective factor(PF)( OR = 2.21, P = 0.001, 95.0% CI=1.356-3.602); the male was the risk factor(RF) contrasted with the female( OR = 0. 515, P =0. 006, 95.0%0 CI = 0.320 - 0. 26) ; ages between 20 and 29 years old had higher likelihood of ROSC than group ≥81 years old( OR = 3.241, P = 0.026, 95.0%CI = 1.146 -9.138); the length of CA time before CPR was RF(OR = 0.913, P = 0.000, 95.0%CI = 0.887-0.948);ventricular fibrillation(VF) was PF compared with asystole( OR = 5.092, P = 0.000, 95.0%CI=2.927 -8.861); electric shock was PF(OR = 3.384, P = 0.000, 95.0%CI = 2.033 - 5.635); epinephrine dosage 0 - 4 mg had higher likelihood of ROSC than > 5 nag dosage( OR = 3. 255, P = 0. 001, 95.0% CI = 1. 606 -6.597). In respect of probability about victims at the tittle reached hospital alive, ages of 2- 12 and 13 - 19 years old had higher rations than ≥81 years old( OR = 12.818, P = 0.029, 95.0% CI = 1.299 - 126.508)( OR = 10.505, P = 0.036, 95.0% CI = 1.161-95.058); the length of CA time before CPR was RF(OR =0.862, P = 0.000, 95.0%CI = 0.821-0.906); VF was PF compared with asystole(OR = 7.330, P =0.000, 95.0%CI = 3.962 - 13.560). Conclusions ECG change before CPR, rescue by the first witness,electric shock, the length of CA time before CPR, epinephrine dosage, gender and age were independent influencing factors of pre-hospital CPR for the emergency of ROSC. Age, the length of CA time before CPR and ECG before CPR were influencing factors of pre-hospital CPR for patients at the time transferred to hospital alive.
