Objective To observe the effect of low tidal volume lung protective ventilation management strategy on postoperative outcome of elderly patients with poor pulmonary function after abdominal surgery.Methods Eighty patients of poor pulmonary function undergoing open gastrointestinal surgery,male 64 cases,female 16 cases,aged over 65 years old,ASA physical status Ⅱ or Ⅲ,NYHA cardiac function Ⅱ or Ⅲ grade,expected operation time 2-4 h were screened.The patients were randomly divided into 2 groups: protective ventilation management group (group P) and conventional mechanical ventilation group (group C),40 cases in each group.Multi-mode anesthetic management was performed in both groups.The respiratory parameters were adjusted according to the group after tracheal intubation,and the respiratory rate was adjusted to maintain PETCO2 35-45 mm Hg.The blood gas evaluated postoperative oxygen and postoperative spontaneous breathing recovery time,recovery time,extubation time,PACU time,gastrointestinal function recovery time,ambulation time,hospital stay and cost of hospitalization were recorded.The occurrence of major complications were observed at 30 days after surgery.Results PaO2 of group C was significantly decreased at 1 and 3 days after surgery than that before operation (P<0.05),PaCO2 of group C was significantly higher at 1 and 3 days after surgery than that of group P (P<0.05);PACU residence time of group P was (76.63±29.72) min,significantly shorter than that of group C [(93.80±42.90) min] (P<0.05);The difference spontaneous breathing recovery time,awake time,extubation time,exhaust time,ambulation time,postoperative hospitalization time and hospitalization expenses of two group was not statistically significant.Within 30 d after operation,2 cases (5%) of respiratory failure patients,3 cases (7.5%) of pneumonia in group P;5 cases (12.5%)of respiratory failure patients,3 cases (7.5%) of pneumonia,postoperative hemorrhage in 1 cases (2.5%) and 1 cases (2.5%) delirium in group C,there was no significant difference of the main complications in 30 d after operation between two groups.Conclusion Under the condition of this research,low tidal volume lung protective ventilation management strategy can improve elderly patients with poor pulmonary function after abdominal surgery postoperative oxygen and help to reduce the occurrence of postoperative adverse reactions.

Objective To study the effects of early application of integrated traditional Chinese medicine (TCM)and western medicine and massage on the incidence and severity of pneumonia and prognosis in the therapeutic course of infants with cytomegalovirus(CMV)infection infantile cholestatic hepatopathy(ICH)accompanied by gastric volvulus(GV). Methods A prospective randomized controlled trial was conducted. 120 infants 1-6 months old with CMV infection ICH and complicated with GV inpatients were divided into treatment group and control group (each,60 cases). The TCM Lidanheji(consisting of artemisiae capillaris 30 g,weeping forsythia 30 g,Chinese goldthread 5 g,prepared rhubarb 5 g,unpeeled root of herbaceous peony 30 g,cassia 5 g,fruit of citron or trifoliate orange 10 g,large-headed atractylodes 10 g,fruit of Chinese magnoliavine 10 g,pangolin scale 3 g and licorice root 5 g)for oral administration or enema and ganciclovir intravenous injection were given to both groups. In the control group,based on the above treatment,postural and diet therapy,prokinetics(domperidone)were given in cases with GV. The massage treatment was only applied for treatment of GV in treatment group. The pneumonia in both groups was treated in accord to the conventional diagnosis and treatment for infantile pneumonia,bronchiolitis,severe pneumonia and the guide and management of infantile community acquired pneumonia. The total number of cases with pneumonia and its severity occurring before and after treatment in the course of the disease,the clinical therapeutic effects of ICH, GV and infantile pneumonia,the clinical physical signs,biochemical indexes and the time of hospitalization were observed and compared between the two groups. Results Compared with control group,after treatment the curative rate and total effective rate of ICH,GV,infant pneumonia in treatment group were significantly higher〔the curative rate of ICH:83.05%(49/59)vs. 71.93%(41/57),total effective rate:96.61%(57/59)vs. 91.23%(52/57);the curative rate of GV:72.88%(43/59)vs. 51.79%(29/56),total effective rate:96.61%(57/59)vs. 78.57%(44/56);the curative rate of infant pneumonia:81.08%(30/37)vs. 67.44%(29/43),total effective rate:100%(37/37)vs. 100%(43/43),P<0.05 or P<0.01〕. In the treatment group,the total number of cases with pneumonia occurring in the therapeutic course and the incidence of severe pneumonia were significantly less than those in the control group〔the occurrence of pneumonia:12 cases vs. 21 cases,the incidence of severe pneumonia:16.67%(2/12) vs. 42.86%(9/21),P<0.05 or P<0.01〕. The enlargement of liver and spleen,the level of total bilirubin(TBil), direct bilirubin(DBil),total bile acids(TBA)and alanine aminotransferase(ALT)in two groups after treatment were significantly lower than those before treatment,the changes being more marked in treatment group(P<0.05 or P<0.01). The time of stay in hospital in treatment group was remarkably shortened(days:21.32±3.26 vs. 27.38±6.09, P<0.05). Conclusion Early interference with combined TCM and western medicine and massage for treatment of infants with CMV infection ICH accompanied by GV can significantly decrease the incidence of pneumonia and its severity occurring in the disease course,therefore this therapeutic method is beneficial to the treatment and prognosis of infants with CMV infection ICH.

Objective To explore the association between PI3K polymorphisms in insulin signal transduction pathway and Alzheimer's disease (AD)risk.Methods There were three groups,including 112 cases for AD +T2D group,231 cases for only AD group,and 231 cases for healthy controls group.The polymorphisms in PI3K gene was sequenced by PCR and the concentration of PI3K in serum was tested by enzyme -linked immunosorbent assay (ELISA).Results Overall,there was significantly statistical difference in PI3K rs3730087 polymorphism among three groups (χ2 =20.99,P =0.000 3).The CC frequency of PI3K rs3730087 polymorphism in AD with T2D group and AD control group was significantly higher than that in the healthy control group.The PI3K protein level of differ-ent genotype was statistically significant (F =27.450,P <0.000 1).As for CC genotypes of PI3K rs3730087 poly-morphism,the PI3K protein level was statistically different among these three groups (F =8.096,P =0.000 6).Moreover,the PI3K protein level of the three groups was different (F =9.034,P =0.000 1),which in both AD group was lower as compared with healthy control group.Conclusion The study suggested that CC genotype of PI3K rs3730087 polymorphism in insulin signaling transduction pathway might be a risk factor for AD with T2D and it also affects the expression level of PI3K protein.However,the polymorphism is not shown to be exclusive in AD patients with T2D.

Objective To improve the efficiency of result reporting and ensure the accuracy of the results by establishing autoverification system in Clinical Chemistry and Immunology Laboratory.Methods The study followed the requirements of the Clinical Laboratory Standards Institute(CLSI)AUTO-10A and ISO 15189:2012.In addition,seven categories of verification rules were encoded using the autoverification function of the CentraLink?Data Management System on the Aptio?Automation platform.These rules included Clinical Diagnostic Standard(CS), Sample Status(SS), Quality Control Severity(QS), Instrument Error Flags Severity(IS), Normal Severity(NS), Delta Check Severity(DS), and Logical Assessment Standard(LS).Various modules of Aptio Automation,laboratory information system(LIS)and hospital information system(HIS)were integrated using the CentraLink system to establish the autoverification system.Results The autoverification system was set up and tested from August 2015 to April 2016.In total, the system ran 4 496 425 tests on 366 180 chemistry specimens.The overall autoverification rate for tests performed increased from 53.4% to 87.0%.Glucose had the highest rate (98.3%)while CKMB had the lowest rate(63.6%).Average TAT for result verification decreased by 97.7%,from 46.3 minutes to 3.7 minutes.The system ran 410,040 tests on 160 119 chemiluminescence specimens.The autoverification rate for tests performed increased from 40.2%to 89%.C-P had the highest rate(98.4%)while A-TPO had the lowest rate(58.7%).Average TAT for result verification decreased by 77.4%,from 14.6 minutes to 3.3 minutes.From May 2016 to January 2017(when autoverification was employed),compared with the same period in 2014(when manual verification was employed),the following changes were observed with no increase in staff capacity:a)Volume of routine chemistry tests increased by 46.4%,and median TAT for tests decreased by 41.9%, from 118 minutes to 83 minutes; b)Volume of chemiluminescence tests increased by 24.5%and median median TAT for tests decreased by 52.4%, from 131 minutes to 86 minutes;c)Median TAT for critical values decreased by 50.5%; d)Rates of tests that did not go through autoverification were 88.2% for NS,6.05% for SS, 2.40% for DS,2.00% for LS, 0.97%for IS,and 0.43% for CS; e)Rates of abnormal specimen status identified by Aptio Automation were 7.13‰for jaundice,5.39‰ for blood lipids,2.20‰ for hemolysis,0.17‰ for barcode error, and 0.15‰ for insufficiency;f)Error rate decreased to 0.00%;and g)staff satisfaction increased from 85%to 100%.Conclusion Autoverification of results by using the CentraLink Data Management System can achieve quality control over the entire process of clinical laboratory testing, ensure accuracy of test results, improve work efficiency, decrease TAT, minimize the error rate, avoid skill variation of staff, reduce the pressure of performing manual verification,and improve medical security.

Objective To observe the clinical characteristics of infants with pertussis syndrome and the influence of gastroesophageal reflux (GER) on pertussis syndrome in small infants, and provide experience for improving curative effect. Methods ① The clinical data of 807 infants with pertussis syndrome treated at Wuhan Children's Hospital from January 2015 to June 2017 were retrospectively analyzed, in which their clinical characteristics including symptoms, signs and related physical and chemical examinations were summarized. ② Prospective randomized controlled trials were performed at the Children's Hospital of Wuhan from June 2017 to June 2018, there were 120 infants with ages < 6 months diagnosed as pertussis syndrome and simultaneously accompanied by gastric volvulus (GV) and GER, and they were randomly divided into a study group and a control group according to the date sequence of definite diagnosis, 60 cases in each group. The control group was given conventional medical treatment, while in the study group, additionally the infants received massage to restore gastric proper position and anti-reflux therapy. The clinical efficacies of two groups were observed. Results ① Retrospective analysis showed that clinically, pertussis syndrome commonly occurred in infants of ages < 6 months, accounting for 88.30% (713 cases); all cases had spastic cough, and 60.00% (484 cases) infants' coughing was severer at night. In laboratory examinations, 83.27% (672 cases) of the infants had elevated platelets (PLT), 25.03% (202 cases) had abnormal myocardial zymograms, and 70.38% (568 cases) had elevated white blood cells (WBC). In the pathogen examination, only were pathogens found in 34.8% infants, mainly single pathogen infection, accounting for 86.12%. Chest radiographs suggested 71.50% of infants with pneumonia, and 73.00% of infants with GER, among which 77.92% of infants were accompanied by GV. ② The prospective study showed that in the treatment of infants with pertussis syndrome accompanied by GV and GER, manual massage should be used timely to correct GV and simultaneously anti-reflux therapy should be given, in the aspects of time required to improve cough symptoms (days: 5.36±1.40 vs. 6.59±1.56, P < 0.01) and shortening of the hospital stay (days: 6.50±1.41 vs. 8.09±1.63, P < 0.01) in the study group were superior to those in the control group; the case of respiratory failure in the study group was lower than that in the control group [2 cases vs. 8 cases, P < 0.05]. Conclusions In pertussis syndrome, lymphocytes occupy the main proportion of WBC elevation that is an important differential criterion between pertussis syndrome and infantile pneumonia with gastric volvulus and gastroesophageal reflux. PLT elevation in pertussis syndrome suggests that attention should be paid to the elevation as that might be related to the disease prognosis. It is necessary to further investigate whether the positive pathogen discovered in the course of pertussis syndrome is a pathogenic one, and attention should also be paid to the medical examination of GV and GER in the small infants with pertussis syndrome, since early proper intervention to correct GV and GER can significantly improve their clinical efficacies.

Objective sampling method was used to conduct a questionnaire survey on outpatients in two hospitals in Guangdong province in order to evaluate patients’ satisfaction with the quality of medical service. This paper explored the factors that affect patients’ evaluation of medical service quality, and found that patients’ age was negatively correlated with the evaluation of medical service quality. It is suggested that the establishment of friendly medical institutions should be carried out according to the national policy. At the same time, the management mechanism of hospital should be improved, the number of medical service centers for "efficient" should be increased, and the medical service personnel should be regularly trained; carry out medical knowledge education in community, improve the popularization of personal medical knowledge and close the cognitive gap between doctors and patients.
