Objective To compare the treatment accomplishmentsand adverse effects of the mixed- or single-application of etomidate and propofol during modified electroconvulsive therapy (MECT) in schizophrenics with hypertension. Methods Ninety hospitalized schizophrenics with hypertension undergoing MECT were ran-domly assigned to 3 groups: Group EP(etomidate = 0.3 mg/kg and propofol = 1.0 mg/kg), Group E (etomi-date = 0.7 mg/kg) and Group P (propofol = 2.0 mg/kg). Changes of SBP, DBP and HR were recorded before anesthesia, after induction, electrical stimulation instantly and 5 min after electrical stimulation. The average pe-riods of epileptic seizure (ESD), postictal suppression index (PSI) and the adverse reactions were also recorded. Results The ESD and PSI scores were significantly higher in Group EP and Group E than those in Group P (P < 0.05). SBP and DBP in Group E were significantly higher at the electrical stimulation instant than those af-ter induction (P < 0.05). SBP and DBP in Group P were significantly lower after induction than those before anesthesia(P < 0.05). The injection pain of Group EP and Group E were lower than that of Group P(P < 0.05). No significant differences were found among 3 groups in the adverse reactions such as nausea/vomiting anddys-phoria.Conclusion The mixed liquor of etomidate and propofol can extend the time of seizure, reduce the nega-tive reaction of cardiovascular system and adverse reactions during MECT in schizophrenics with hypertension.

Objective To explore the risk factors affecting the quality of life (QOL) of patients with obstructive sleep apnea (OSAS) and the influence of nasal continual positive airway pressure (nCPAP) treatment on the QOL of OSAS patients. Methods Measuring the quality of life of 212 patients suffered from OSAS with WHOQOL-BREF and analyzing the influences of the sleepiness, quality of sleep, chronic disease and nCPAP treatment on the QOL of patients with OSAS. Results The scores on physical domain and psychological domain of patients who were sleepiness or had bad quality of sleep were less than that of patients who were non-sleepiness or had a good sleep respectively(P

Objective To explore the clinical significance of combined detection of carbohydrate antigen(CA)125,CA153,carcinoembryonic antigen(CEA) and tumor specific growth factor(TSGF) in diagnosis for breast cancer.Methods A total of 125 patients with breast cancer were recruited as objects in this study from march 2015 to march 2016,65 patients in breast cancer group,60 patients in benign breast disease group,meanwhile 55 healthy person were enrolled in the control group.Serum tumor markers such as CA125,CA153,CEA and TSGF were detected and compared in the three groups.Results The serum CA125,CA153,CEA and TSGF levels in the breast cancer group were significant higher than those of benign breast disease group and healthy group,the differences were statistical significant(P<0.05).At the same time,the sensitivity and specificity of joint detection of four kinds of serum tumor marker were 90.2% and 88.9%,which were higher than those of single serum tumor marker detection(χ2=26.12,P<0.05).Conclusion The four kinds of serum tumor markers combined testing not only increases the sensitivity of breast cancer diagnosis,but also improved the specificity of diagnosis of breast cancer.

Objective To investigate the operative techniques for refractory cholelithiasis. Methods The clinical data of 521 patients with refractory cholelithiasis who had been admitted to People's Hospital of Hunan Province from January 1990 to December 2007 were retrospectively analyzed. Results All patients received surgery. After the operation, 3 patients died of liver and kidney failure, the remaining 518 patients were cured without severe complications. The results of B ultrasound and computed tomography showed residual stones in 78 patients (15.1%). Four hundred and twenty-three patients (81.7%) were followed up for 5 months to 17 years (mean, 7.5 years), and the rate of positive effect was 90.1% (381/423). Conclusions Most of the refractory cholelithiasis can be cured radically. Individualized surgical planning, fine and standard surgical procedure are key to the treatment effect.

Objective To reseach the time point of the highest percentage of neural precursor cells derived from adipose stromal cells (ADSCs) in vitro, and to observe the ultrastructure features of neural precursor cells. Methods Used the β-mercaptoethanol to induce ADSCs to differentiate into neural precursor cells and neuron-like cells. The morphology of the uninductedcells and inducted cells were observed with inverted phase contrast microscope. The expression of nestin which was the marker of neural precursor cell in each group was detected using immunofluorescence staining method. The ultrastructural feature of cells which was induced for 3 hours were observed. Results The highest ratio of positive expression of nestin was 3 hours following induction,with the ratio ( 86.25 ± 4.82) %. There were many protuberance on the cell membrane under transmission electron microscopy.There were plenty of organelles in the neural precursor cells. The neural precursor cells had a large size nucleus,large nucleoplasmic index, much extended chromatin,and less condensed chromatin. The nucleus had double-layer nuclear envelope, more nuclear pore on the nuclear envelope. Conclusion The time point of the highest percentage of neural precursor cells derived from ADSCs is 3 hours,and the ultrastructral feature of induced neural precursor cells confirm that cells at this time point are in a state of split active period.

Objective To summarize the main early complications after pancreatoduodenectomy and analysis of the probable causes.Methods The clinical data of 576 cases who underwent pancreatoduodenectomy(PD) in our department between Feb 1990 and May 2009 were analysed retrospectively.Results There were 92 early postoperative complications occurred in 85 patients(14.8%).Gastrointestinal dysfunction,pancreatic leakage,intra-abdominal infections and hemorrhage were the most of complications,and 7 cases died during perioperative period(mortality 1.22%),among which 3 died of multiple system organ failure,2 died of hemorrhagic shock and 2 died of toxic shock.Preoperative hypoproteinemia and hyperbilirubinemia complicated with a high incidence of postoperative complications on multivariate analysis.Conclusions Meticulous preoperative preparation,delicate intraoperative technigne and close postoperative observation are the key points to decrease early complications and improve the prognosis of the patients who undergo PD.

Objective To investigate publication of papers by nursing staff in a TCM hospital and to find out the problems as well as countermeasures.Method A retrospective analysis about authors,education,academictitle,length of service and age was done to investigate the classes of published papers from 2008 to 2012.Results The academic publication by the nurses from 2008 to 2012 was increased.Among these articles,the TCM nursing techniques took up the largest ratio,which accounted for 29.12%. There were significant differences in ages,length of service and educational background in authors(P<0.05).Conclusions Nurses’ awareness and capabilities of publishing academic papers needs enhancement as well as training.It may be significant to strengthen their incentives in scientific research by enforcing encouraging policies.

Objective To compare the pharmacokinetics of borneolum syntheticum(BS)and borneol in compound Danshen dropping pills in rats.Method Rats were administrated orally with BS or Danshen dropping pills containing equal amount of borneol in a single dose.The blood contents of borneol at a series of time points were assayed by GC-MS and GC-FID after administration.The drug-time curve was estimated by PK Solution 2.0 pharmacokinetic software(USA).Results The pharmacokinetic parameters are quite different between the single dose of BS and the borneol in the compound Danshen dropping pills:the velocity constants of absorption(2.630h-1),distribution(1.788 h-1)and elimination(0.273 h-1)of BS were much greater than those(1.635h-1,0.784h-1,0.116h-1)of the same quantity of borneol in compound Danshen dropping pills,while the Tmax(0.5 h)of former was shorter than that(0.75 h)in the latter,and the Cmax(16.8 ?g/mL)in the former was about half of the latter(31.02 ?g/mL).And,at the 18h after administration,the former blood concentration(0.043 ?g/mL)was approximately one tenth of the latter.Conclusion It is suggested that we should pay attention to the influence of other ingredients on the main objective component in the study of pharmacokinetics of compound traditional chinese drug.
