ObjectiveAnalyze preoperative clinical relevanted factors of acute type A aortic dissection with hypoxemia according to a group clinical data.MethodsFrom January 2011 to June 2011,we have collected 54 preoperative cases of acute type A aortic dissection,including 42 males,12 females,aged 28-73 years old,onset to treatment time is 0.4-14.0 days.General information:age,gender,time of onset,body mass index,hypertension,diabetes mellitus,smoking,drinking,heart ejection fraction,prothrombin time,quantitative fibrinogen,fibrinogen degradation products,D-dimer,C-reactive protein,procalcitonin,ICU time,length of hospital stay.According to the blood gas analysis of quiet state case without oxygen,with PaO2 ＜ ( 100-age ×0.33 ±5) mm Hg is for the hypoxemia group,equal or higher than this is no-hypoxemia group.ResultsNo-hypoxemia group has 14 cases,11 males,3 females,average aged (51.14 ± 14.24) years old,including 12 operation patients ( no death) and 2 no-operation patients(2 cases death).Hypoxemia group has 40 cases,31 males,9 females,average aged (50.53 ± 9.73 ) years old,including 33 operation patients(2 cases death) and 7 no-operation patients(7 cases death).There is no significant difference in age,gender,time of onset,hypertension,diabetes mellitus,smoking,drinking,cardiac ejection fraction,prothrombin time and fibrinogen.There is statistically significant on body mass index,fibrinogen degradation products,D-dimer,C-reactive protein,procalcitonin,ICU time and length of hospital stay time ( P ＜ 0.05 ).ConclusionPreoperative hypoxemia with acute type A aortic dissection is associated with obesity,excessive inflammation and activation of coagulation and fibrinclytic system,and hypoxemia may prolong the time of operative patients with acute type A aortic dissection in ICU and hospital.

Objective To explore the safety and feasibility of performing total thoracoabdominal aortic aneurysm repair (tTAAAR) under normal thermia and non-cardiopulmonary bypass fashion by comparing surgical indications and details of different surgical strategies in tTAAAR.Methods From February 2009 to May 2011,46 consecutive patients with extensive Crawford Ⅱ thoracoabdominal aortic aneurysm (TAAA)underwent total thoracoabdominal aortic aneurysm repair( tTAAAR ) in An Zhen Hospital.The patients were divided into 2 groups ( A and B) according to their different surgical strategies.Patients in group A underwent total thoracoabdominal aortic aneurysm repair with deep hypothermia and circulatory arrest.Patients in group B underwent total thoracoabdominal aortic aneurysm repair in a normal thermia and non-circulatory bypass was performed via a combined left thoracoabdominal incision.After established the bypass from descending aorta to bilateral iliac arteries under normal thermia,the reestablishment of intercostal arteries and visceral arteries was followed with subsection circulatory arrest.The clinical results of these 2 groups were analyzed by SPSS 18.0.Results Patients in group A underwent total thoracoabdominal aortic aneurysm repair with deep hypothermia and circulatory arrest have higher mortality rate and transient nervous dysfunction rate (26.67％ vs 3.20％,P =0.033 ; 33.30％ vs 3.30％,P =0.018,respectively) than patients in group B underwent total thoracoabdominal aortic aneurysm repair in a normal thermia and non-circulatory bypass.Statistical significance was also observed between group A and circulatory arrest and group B in operation time,descending aortic clamping time,and transfusiori volume of red blood cells ( P ＜ 0.05 ).Average age,sex,pathological type,the maximal diameters of aneurysm,preoperative complications,visceral ischemia time,spinal cord ischemia time,ICU treatment time,intubation time,respiratory complications,plasma dosage,platelets dosage,RBC dosage,thoracotomy hemostatic,spinal cord injury,renal insufficiency were found no statistical significance(P ＞ 0.05 ) between two groups.In addition to death and paraplegia,the others were cured.Conclusion The normal thermia and non-cardiopulmonary bypass tTAAAR is a safe and feasible therapeutic strategy for TAAA patients.A bypass from descending aorta to iliac arteries can be built under normal thermia in TAAA patients,which is the indication of this new technique.Reestablishment of intercostal arteries is an important protective adjunct to avoid spinal cord injury.

Objective To evaluate the efficacy of Disposcope endoscope(DE)-guided nasotrache-al intubation in patients with difficult airway by comparing with fiberoptic bronchoscope(FOB). Methods One hundred and twenty American Society of Anesthesiologists physical statusⅠ-Ⅲ patients of both se-xes, with body mass index<25 kg∕m2, aged 18-64 yr, with mouth opening<3 cm, of Mallampati classifi-cation Ⅲ or Ⅳ, undergoing maxillofacial surgery requiring nasotracheal intubation were divided into DE group(n=60)and FOB group(n=60)using a random number table.Nasotracheal intubation was per-formed under the guidance of DE or FOB after induction of anesthesia.Glottis exposure was evaluated using Cormack-Lehane grade.Epistaxis during intubation, successful intubation, time and degree of glottis expo-sure, intubation time and development of tachycardia and hypertension and requirement for assisted ventila-tion with face mask during intubation were recorded.The patients were followed up postoperatively, and the development of intubation-related complications was also recorded.Results Compared with group FOB, glottis exposure time and incubation time were significantly shortened(P<0.05), and no significant change was found in Cormack-Lehane grade, rate of successful incubation, rate of successful intubation at first attempt or intubation-related complications in group DE(P>0.05). Hypertension and tachycardia were not found and no patients required assisted ventilation with face mask during intubation in the two groups.Conclusion DE-guided nasotracheal intubation provides similar efficacy to that of FOB with shorter time and is an optimal selection for the patients with difficult airway.

Objective To evaluate the effect of propofol on high-mobility group box 1 protein (HMGB1)/Toll-like receptor 4 (TLR4) signaling pathway during hepatic ischemia-reperfusion (I/R) injury in rats.Methods Thirty-six clean-grade healthy male Sprague-Dawley rats,aged 3 months,weighing 250 -300 g,were divided into 3 groups (n=12 each) using a random number table method:sham operation group (group S),hepatic I/R group (group I/R) and propofol group (group P).Hepatic I/R injury was induced by occluding the portal vein and hepatic artery supplying the left and middle lobes of the liver for 1 h followed by 6-h reperfusion in anesthetized rats.Propofol was infused via the tail vein at a rate of 12 mg ·kg-1 · h-1 starting from 20 min before ischemia until 6 h of reperfusion in group P.The rats were sacrificed at 6 h of reperfusion,and the left lobe of the liver was removed for microscopic examination of the pathological changes which were scored and for determination of the expression of HMGB1,TLR4,tumor necrosis factor-alpha (TNF-α) and interleukin-1 beta (IL-6) in liver tissues (by Western blot).Results Compared with group S,pathological scores of liver tissues were significantly increased,and the expression of HMGB1,TLR4,TNF-α and IL-6 was up-regulated in I/R and P groups (P＜0.05).Compared with group I/R,pathological scores of liver tissues were significantly decreased,and the expression of HMGB1,TLR4,TNF-α and IL-6 was down-regulated in group P (P＜ 0.05).Conclusion The mechanism by which propofol reduces liver I/R injury is associated with blocking HMGB-1/TLR4 signaling pathway and inhibiting inflammatory responses in rats.

Objective:To explore the moderating effect of sense of coherence in the relationship between occupational stress and depression.Methods:From June to September in 2018, migrant workers were purposively selected from the urban (including office buildings, shopping malls, barber shops or restaurants and other service enterprises) and suburban (including microelectronics, internet, clothing processing and art design and other factories) areas of Shanghai. A total of 3 034 people were investigated and 2 573 valid questionnaires were collected. Patient health questionnaire (PHQ), sense of coherence questionnaire (SOC) and job content questionnaire (JCQ) were used to investigate the levels depression, sense of coherence and occupational stress. Hierarchical regression analysis was used to analyze the moderating effect of sense of coherence on occupational stress and depression, and SPSS PROCESS macro program and Bootstrap method were used to further explore the moderating effect of sense of coherence.Results:The age of total 2 573 migrant workers was (28.24±7.33) years old and 49.79% of them were males. The scores of depression, occupational stress and sense of coherence were 6.67±4.74, 28.45±4.38 and 62.02±10.89, respectively. The depression level was positively correlated with occupational stress ( r=0.33, P=0.007), and negatively correlated with sense of coherence ( r=-0.53, P=0.003). The hierarchy regression analysis suggested that the interaction between occupational stress and sense of coherence was associated with depression symptom (β=-0.07, P=0.001). Bootstrap analysis showed that occupational stress was not associated with depression symptom with high level of sense of sense of coherence (β=0.04, 95% CI=-0.01-0.10), while occupational stress was associated with depression symptom with low level of sense of sense of coherence (β=0.19, 95% CI=0.14-0.23). Conclusion:The high level of sense of coherence has a moderating effect on the relationship between occupational stress and depressive symptoms, while the low level of sense of coherence does not have this effect.

Objective This study aimed to explore the spatial heterogeneity and risk factors for dental caries in 12-year-old children in Shanxi province,China. Methods The data encompassed 3,721 participants from the two most recent oral health surveys conducted across 16 districts in Shanxi Province in 2015 and 2018.Eighteen specific variables were analyzed to examine the interplay between socioeconomic factors,medical resources and environmental conditions.The Geo-detector model was employed to assess the impacts and interactions of these ecological factors. Results Socioeconomic factors(Q=0.30,P<0.05)exhibited a more substantial impact compared to environmental(Q=0.19,P<0.05)and medical resource factors(Q=0.25,P<0.05).Notably,the urban population percentage(UPP)demonstrated the most significant explanatory power for the spatial heterogeneity in caries prevalence,as denoted by its highest q-value(q=0.51,P<0.05).Additionally,the spatial distribution's heterogeneity of caries was significantly affected by SO2 concentration(q=0.39,P<0.05)and water fluoride levels(q=0.27,P<0.05)among environmental factors. Conclusion The prevalence of caries exhibited spatial heterogeneity,escalating from North to South in Shanxi Province,China,influenced by socioeconomic factors,medical resources,and environmental conditions to varying extents.

OBJECTIVETo investigate the current status of occupational stress and presenteeism among medical staff at grade A tertiary hospitals in Shanghai, China, and to analyze the association between occupational stress and presenteeism.

METHODSA total of 2356 healthcare workers from eight grade A tertiary hospitals in Shanghai were investigated by stratified random sampling. All the subjects were asked to complete self-administered questionnaires with informed consent. The occupational stress was assessed by the occupational stress core questionnaire. The presenteeism was evaluated by the Stanford Presenteeism Scale.

RESULTSIn all subjects, the average score of presenteeism was 15.23 ± 3.89, and 72.5% felt occupational stress in self-evaluation. There were significant differences in the score of presenteeism between subjects with different ages, education levels, occupations, lengths of service, job titles, and shifts (all P<0.05). There were significant differences in the score of presenteeism and the rate of high presenteeism between subjects with different indices of occupational stress, including job demand, control, social support, and demand-control ratio (P<0.01). High job demand and high demand-control ratio were risk factors for high presenteeism (OR=2.56, 95% CI=2.01~3.27; OR=1.53, 95% CI=1.23~1.90). High social support was a protective factor for high presenteeism (OR=0.23, 95% CI=0.18~0.29).

CONCLUSIONThe intensity of occupational stress in medical staff from grade A tertiary hospitals is positively correlated with the level of presenteeism. It is important to promote social support to reduce the loss of work efficiency due to presenteeism.

Objective:To investigate the epidemiological characteristics, diagnosis, treat-ment and prognosis of gallbladder cancer in China from 2010 to 2017.Methods:The single disease retrospective registration cohort study was conducted. Based on the concept of the real world study, the clinicopathological data, from multicenter retrospective clinical data database of gallbladder cancer of Chinese Research Group of Gallbladder Cancer (CRGGC), of 6 159 patients with gallbladder cancer who were admitted to 42 hospitals from January 2010 to December 2017 were collected. Observation indicators: (1) case resources; (2) age and sex distribution; (3) diagnosis; (4) surgical treatment and prognosis; (5) multimodality therapy and prognosis. The follow-up data of the 42 hospitals were collected and analyzed by the CRGGC. The main outcome indicator was the overall survival time from date of operation for surgical patients or date of diagnosis for non-surgical patients to the end of outcome event or the last follow-up. Measurement data with normal distribu-tion were represented as Mean±SD, and comparison between groups was conducted using the t test. Measurement data with skewed distribution were represented as M( Q1, Q3) or M(range), and com-parison between groups was conducted using the U test. Count data were described as absolute numbers or percentages, and comparison between groups was conducted using the chi-square test. Univariate analysis was performed using the Logistic forced regression model, and variables with P<0.1 in the univariate analysis were included for multivariate analysis. Multivariate analysis was performed using the Logistic stepwise regression model. The life table method was used to calculate survival rates and the Kaplan-Meier method was used to draw survival curves. Log-rank test was used for survival analysis. Results:(1) Case resources: of the 42 hospitals, there were 35 class A of tertiary hospitals and 7 class B of tertiary hospitals, 16 hospitals with high admission of gallbladder cancer and 26 hospitals with low admission of gallbladder cancer, respectively. Geographical distribution of the 42 hospitals: there were 9 hospitals in central China, 5 hospitals in northeast China, 22 hospitals in eastern China and 6 hospitals in western China. Geographical distribution of the 6 159 patients: there were 2 154 cases(34.973%) from central China, 705 cases(11.447%) from northeast China, 1 969 cases(31.969%) from eastern China and 1 331 cases(21.611%) from western China. The total average number of cases undergoing diagnosis and treatment in hospitals of the 6 159 patients was 18.3±4.5 per year, in which the average number of cases undergoing diagnosis and treatment in hospitals of 4 974 patients(80.760%) from hospitals with high admission of gallbladder cancer was 38.8±8.9 per year and the average number of cases undergoing diagnosis and treatment in hospitals of 1 185 patients(19.240%) from hospitals with low admission of gallbladder cancer was 5.7±1.9 per year. (2) Age and sex distribution: the age of 6 159 patients diagnosed as gallbladder cancer was 64(56,71) years, in which the age of 2 247 male patients(36.483%) diagnosed as gallbladder cancer was 64(58,71)years and the age of 3 912 female patients(63.517%) diagnosed as gallbladder cancer was 63(55,71)years. The sex ratio of female to male was 1.74:1. Of 6 159 patients, 3 886 cases(63.095%) were diagnosed as gallbladder cancer at 56 to 75 years old. There was a significant difference on age at diagnosis between male and female patients ( Z=-3.99, P<0.001). (3) Diagnosis: of 6 159 patients, 2 503 cases(40.640%) were initially diagnosed as gallbladder cancer and 3 656 cases(59.360%) were initially diagnosed as non-gallbladder cancer. There were 2 110 patients(34.259%) not undergoing surgical treatment, of which 200 cases(9.479%) were initially diagnosed as gallbladder cancer and 1 910 cases(90.521%) were initially diagnosed as non-gallbladder cancer. There were 4 049 patients(65.741%) undergoing surgical treatment, of which 2 303 cases(56.878%) were initially diagnosed as gallbladder cancer and 1 746 cases(43.122%) were initial diagnosed as non-gallbladder cancer. Of the 1 746 patients who were initially diagnosed as non-gallbladder cancer, there were 774 cases(19.116%) diagnosed as gallbladder cancer during operation and 972 cases(24.006%) diagnosed as gallbladder cancer after operation. Of 6 159 patients, there were 2 521 cases(40.932%), 2 335 cases(37.912%) and 1 114 cases(18.087%) undergoing ultrasound, computed tomography (CT) or magnetic resonance imaging (MRI) examination before initial diagnosis, respec-tively, and there were 3 259 cases(52.914%), 3 172 cases(51.502%) and 4 016 cases(65.205%) undergoing serum carcinoembryonic antigen, CA19-9 or CA125 examination before initially diagnosis, respectively. One patient may underwent multiple examinations. Results of univariate analysis showed that geographical distribution of hospitals (eastern China or western China), age ≥72 years, gallbladder cancer annual admission of hospitals, whether undergoing ultrasound, CT, MRI, serum carcinoembryonic antigen, CA19-9 or CA125 examination before initially diagnosis were related factors influencing initial diagnosis of gallbladder cancer patients ( odds ratio=1.45, 1.98, 0.69, 0.68, 2.43, 0.41, 1.63, 0.41, 0.39, 0.42, 95% confidence interval as 1.21-1.74, 1.64-2.40, 0.59-0.80, 0.60-0.78, 2.19-2.70, 0.37-0.45, 1.43-1.86, 0.37-0.45, 0.35-0.43, 0.38-0.47, P<0.05). Results of multivariate analysis showed that geographical distribution of hospitals (eastern China or western China), sex, age ≥72 years, gallbladder cancer annual admission of hospitals and cases undergoing ultrasound, CT, serum CA19-9 examination before initially diagnosis were indepen-dent influencing factors influencing initial diagnosis of gallbladder cancer patients ( odds ratio=1.36, 1.42, 0.89, 0.67, 1.85, 1.56, 1.57, 0.39, 95% confidence interval as 1.13-1.64, 1.16-1.73, 0.79-0.99, 0.57-0.78, 1.60-2.14, 1.38-1.77, 1.38-1.79, 0.35-0.43, P<0.05). (4) Surgical treatment and prognosis. Of the 4 049 patients undergoing surgical treatment, there were 2 447 cases(60.435%) with complete pathological staging data and follow-up data. Cases with pathological staging as stage 0, stage Ⅰ, stage Ⅱ, stage Ⅲa, stage Ⅲb, stage Ⅳa and stage Ⅳb were 85(3.474%), 201(8.214%), 71(2.902%), 890(36.371%), 382(15.611%), 33(1.348%) and 785(32.080%), respectively. The median follow-up time and median postoperative overall survival time of the 2 447 cases were 55.75 months (95% confidence interval as 52.78-58.35) and 23.46 months (95% confidence interval as 21.23-25.71), respectively. There was a significant difference in the overall survival between cases with pathological staging as stage 0, stage Ⅰ, stage Ⅱ, stage Ⅲa, stage Ⅲb, stage Ⅳa and stage Ⅳb ( χ2=512.47, P<0.001). Of the 4 049 patients undergoing surgical treatment, there were 2 988 cases(73.796%) with resectable tumor, 177 cases(4.371%) with unresectable tumor and 884 cases(21.833%) with tumor unassessable for resectabi-lity. Of the 2 988 cases with resectable tumor, there were 2 036 cases(68.139%) undergoing radical resection, 504 cases(16.867%) undergoing non-radical resection and 448 cases(14.994%) with operation unassessable for curative effect. Of the 2 447 cases with complete pathological staging data and follow-up data who underwent surgical treatment, there were 53 cases(2.166%) with unresectable tumor, 300 cases(12.260%) with resectable tumor and receiving non-radical resection, 1 441 cases(58.888%) with resectable tumor and receiving radical resection, 653 cases(26.686%) with resectable tumor and receiving operation unassessable for curative effect. There were 733 cases not undergoing surgical treatment with complete pathological staging data and follow-up data. There was a significant difference in the overall survival between cases not undergoing surgical treatment, cases undergoing surgical treatment for unresectable tumor, cases undergoing non-radical resection for resectable tumor and cases undergoing radical resection for resectable tumor ( χ2=121.04, P<0.001). (5) Multimodality therapy and prognosis: of 6 159 patients, there were 541 cases(8.784%) under-going postoperative adjuvant chemotherapy and advanced chemotherapy, 76 cases(1.234%) under-going radiotherapy. There were 1 170 advanced gallbladder cancer (pathological staging ≥stage Ⅲa) patients undergoing radical resection, including 126 cases(10.769%) with post-operative adjuvant chemotherapy and 1 044 cases(89.231%) without postoperative adjuvant chemo-therapy. There was no significant difference in the overall survival between cases with post-operative adjuvant chemotherapy and cases without postoperative adjuvant chemotherapy ( χ2=0.23, P=0.629). There were 658 patients with pathological staging as stage Ⅲa who underwent radical resection, including 66 cases(10.030%) with postoperative adjuvant chemotherapy and 592 cases(89.970%) without postoperative adjuvant chemotherapy. There was no significant difference in the overall survival between cases with postoperative adjuvant chemotherapy and cases without postoperative adjuvant chemotherapy ( χ2=0.05, P=0.817). There were 512 patients with pathological staging ≥stage Ⅲb who underwent radical resection, including 60 cases(11.719%) with postoperative adjuvant chemotherapy and 452 cases(88.281%) without postoperative adjuvant chemotherapy. There was no significant difference in the overall survival between cases with postoperative adjuvant chemo-therapy and cases without post-operative adjuvant chemo-therapy ( χ2=1.50, P=0.220). Conclusions:There are more women than men with gallbladder cancer in China and more than half of patients are diagnosed at the age of 56 to 75 years. Cases undergoing ultrasound, CT, serum CA19-9 examination before initial diagnosis are independent influencing factors influencing initial diagnosis of gallbladder cancer patients. Preoperative resectability evaluation can improve the therapy strategy and patient prognosis. Adjuvant chemotherapy for gallbladder cancer is not standardized and in low proportion in China.
