Objective To evaluate the efficacy and safety of the damage-controlling surgery for the elderly patients with obstructive biliary diseases. Methods 278 elderly patients with obstructive biliary diseases were divided into the damage-controlling surgery group and definite surgery group.The obstructive biliary diseases were divided into the benign obstructive group and the malignant obstructive group. The complication rate and mortality between the 2 groups were analyzed and compared. Results One hundred and eighteen elderly patients were treated by damage-contolling surgery, its complication rate was 9.32 % and the mortality was 0 %. One hundred and sixty elderly patients,were treated by definite surgery, its complication rate was 24.38%, the mortality was 6.88%. There were significant differences in complication rate and mortality between the damage-controlling surgery group and the definite surgery group (all P＜0.01). The complication rate of the benign obstructive diseases group treated by damage-controlling surgery was 17.3%, the mortality was 0%. The complication rate of the benign obstructive diseases group treated by definite surgery was 16.3%, the mortality was 4.34%. There was no significant difference in the complication rate and mortality between the 2 groups (all P＞0.05). The complication rate and mortality of the malignant obstructive biliary diseases group treated by damage-controlling surgery were 4.45% and 0% respectively, and were 35.29% and 10.29% by definite surgery, there were significant differences in the complication rate and mortality between the 2 groups (P＜0.01 and P＜0.05). Conclusions Damage-controlling surgery may decrease the complication rate and mortality of the elderly patients with obstructive biliary diseases, and improve the operation safety of the elderly patients.

Objective To provide the evidences for the management strategies of ventilator-associated pneumonia (VAP) in neonates,we systematically reviewed all related studies and analyzed the high-risk primary disease and medical factors of VAP in neonates.Methods We retrieved all related studies in CNKI,Wanfang,VIP,CBM,Pubmed and Embase and evaluated their quality by Newcastle-Ottawa Scale and analyzed all data by qualitative and Meta-analysis.Results There were 12 case-control studies with higher methodological quality and involving 1 994 neonates and with 708 VAP patients.Six studies involving 872 neonates were included,the odds ratio of respiratory distress syndrome(OR=2.81) and malnutrition(OR=5.18) had significant differences between VAP and non-VAP group.Seven studies involving 1 110 neonates were included and the odds ratio of patients with corticosteroids (OR=3.12),central inhibitors (OR=2.31),antacids (OR=4.35) and Gamma globulin with large doses (OR=2.35) had significant differences between VAP group and non VAP.Four studies involving 554 neonates were included and the odds ratio of patients with closed chest drainage (OR=1.81)and umbilical vein catheterization (OR=9.19) had significant differences between VAP group and non VAP.Six studies involving 1 139 neonates were included and the odds ratio of patients with parenteral nutrition (OR=1.82)and blood transfusions (OR=2.49) had significant differences between VAP group and non VAP.Conclusions Our study confirms that the respiratory distress syndrome and malnutrition corticosteroids,central inhibitors,antacids,Gamma globulin with large doses,closed chest drainage,umbilical vein catheterization,parenteral nutrition and blood transfusions are important risk and early-warning factors.

Objective:To investigate the clinical characteristics of elderly patients with coronavirus disease 2019(COVID-19), in order to provide scientific evidence for the diagnosis and treatment of COVID-19 in elderly patients.Methods:Clinical data of 102 patients with COVID-19 admitted to the B11 East Ward of the Zhongfaxincheng campus and the E1-3 ward of the Guanggu Campus of Tongji Hospital affiliated to Huazhong University of Science and Technology in Wuhan from 1 February 2020 to 28 February 2020 were retrospectively collected and analyzed.Patients were categorized into 2 groups: the elderly group(≥60 years old)and the young and middle-aged group(<60 years old). Differences in epidemiological features, demographics, clinical symptoms, laboratory results and imaging findings between the two groups were retrospectively analyzed.Results:Among 102 patients with COVID-19, 58 were in the elderly group(≥60 years old), with a median age of 67.0(63.8, 71.0)years old, and 44 in the young and middle-aged group(<60 years old), with a median age of 47.5(38.0, 51.8)years old.There was no significant difference in gender ratio between the two groups( χ2=0.033, P=0.855). Of 102 patients, 42.0%(21/50)had close contact with an infected person, 14.0%(7/50)were from infection clusters, and 18.0%(9/50)had suspected hospital-acquired infections.Fever and cough remained the most common symptoms, but gastrointestinal symptoms such as nausea, poor appetite, diarrhea and muscle cramps were also warning signs.Fatigue and cough were the most common presenting symptoms in elderly male patients.Bilateral patchy infiltrates(57.9%, 22/38)and ground-glass opacities(42.1%, 16/38)were the main imaging features and 42.1%(16/38)patients had multiple areas of the lungs involved.Over 50% patients had increased levels of blood glucose, D-dimer, fibrinogen, C-reactive protein, procalcitonin, multiple cytokines and neutrophil-to-lymphocyte ratio, as well as decreased levels of albumin, hemoglobin, hematocrit, lymphocytes and serum calcium.Compared with the young and middle-aged group, the elderly group had higher rates of abnormality in levels of D-dimer and serum calcium( χ2=7.067 and 4.166, P=0.008 and 0.041). Conclusions:Fever and cough are the most common symptoms in elderly patients with COVID-19.Elderly patients with COVID-19 have multiple abnormalities in clinical laboratory test results, which show a certain level of specificity compared with young and middle-aged patients.

Objective To explore the diagnostic value of lymphocyte subpopulations combined with chemokines in children with immunologic thrombocytopenic purpura(ITP).Methods 132 children with proposed diagnosis of ITP were collected,and the children were divided into ITP and non-ITP groups according to the diagnostic results of ITP-related clinical diagnostic criteria.6 ml of peripheral venous blood was drawn,the levels of CD4+CD8+and CD3+were detected using flow cytometry,and the levels of chemokine(C-C motif)ligand 5(CCL5),Recombi-nant Chemokine(C-X-C Motif)Ligand 1(CXCL11),and monocyte chemotactic protein-1(MCP-1)were detec-ted using enzyme-linked immunosorbent assay,the blood platelet(PLT)was measured by a fully automated cell an-alyzer.The children were divided into ITP and non-ITP groups according to the clinical diagnostic criteria related to ITP.The lymphocyte subpopulations and chemokine levels of the two groups of children were compared,and the correlation between lymphocyte subpopulations and chemokine levels and PLT was analyzed.The ROC method was used to evaluate the diagnostic efficacy of individual and combined detection of each indicator for ITP.Results The levels of CD4+and CD3+in the ITP group were lower than those in the non ITP group(P<0.05),while the levels of CD8+were higher than those in the non ITP group(P<0.05).The levels of CCL5,CXCL11,and MCP-1 in the ITP group were higher than those in the non ITP group(P<0.05).The correlation analysis results showed that CD4+,CD3+and platelet count were positively correlated in the ITP group(P<0.05),while CD8+,CCL5,CXCL11,MCP-1 were negatively correlated with PLT(P<0.05).The ROC analysis results showed that the cut-off values of CD4+,CD8+,CD3+,CCL5,CXCL11,and MCP-1 for the diagnosis of ITP in children were 27.13%,24.02%,59.88%,41.02 ng/L,30.18 ng/L,and 188.27 ng/L,respectively.The AUC values were 0.893,0.880,0.629,0.801,0.892,and 0.751,respectively,The AUC of the parallel diagnosis(meaning that one or more of CD4+,CD3+was below the cut-off value and/or one or more of CD8+,CCL5,CXCL11,MCP-1 was above the cut-off value at the time of parallel testing)was 0.967,indicating that one or more of them was lower than the cut off value and/or one or more of them was higher than the cut off value when tested separately.Its diag-nostic efficacy was higher than that of each indicator tested separately(P<0.05).Conclusion There are signifi-cant differences in lymphocyte subpopulations and chemokines between pediatric ITP patients and non-ITP patients.CD4+,CD8+,CD3+,CCL5,CXCL11,and MCP-1 can be used for the diagnosis of pediatric ITP.Combined de-tection of various indicators can improve detection efficiency.

Objective:To investigate the efficacy and safety of recombinant activated factor Ⅶ(rFⅦa)on uncontrolled perioperative hemorrhage in elderly patients in surgical intensive care unit(SICU).Methods:Clinical data of 27 elderly patients with uncontrolled perioperative hemorrhage treated successfully with rFⅦa in surgery-ICU of our hospital from May 2004 to December 2018 were retrospectively analyzed.And the application method and experience were summarized.Results:Of the 27 patients, 16 cases were cured, 11 cases died, and the total fatality rate was 40.74%(11/27). The bleeding stopped in 23 cases, four cases died of uncontrolled peri-operative hemorrhage, and the hemorrhage-caused fatality rate was 14.81%(4/27). Seven patients died of primary diseases after the control of bleeding, with a fatality rate of 25.93%(7/27 ). The thrombin time(TT), prothrombin time(PT), activated partial thromboplastin time(APTT)and international normalized ratio(INR)were reduced and the prothrombin activity(AT)was increased after versus before the application of rFⅦa( Z=-2.197, -3.180, -2.271, -2.803 and 2.756, P=0.028, 0.001, 0.023, 0.005 and 0.006, respectively). Conclusions:rFⅦa has a better effect on uncontrolled peri-operative hemorrhage in elderly patients, when traditional treatments are ineffective.

Objective:To evaluate the new model of group screening combined with opportunistic screening for the diagnosis and treatment of gastric cancer.Methods:Group screening combined with opportunistic screening was used for gastric cancer screening. (1) Group screening. Cluster sampling was used to screen gastric cancer by endoscopy in high-risk population (aged 40-<70 years) of rural residents in Weihai from July 2017 to December 2020, and biopsy was obtained for histopathology if necessary. Main collection parameters included the detection rate of advanced gastric cancer, early gastric cancer and high-grade intraepithelial neoplasia (HGIN). (2) Opportunistic screening. The changes of the detection rates of early gastric cancer in opportunistic screening in 2 hospitals in Weihai area were observed during the same period of time.Results:(1) In group screening, from July 2017 to December 2020, the first batch of 8 000 cases of gastric cancer screening were completed. The cases of advanced gastric cancer, early gastric cancer and HGIN were 36, 28, and 62, respectively. The detection rates of gastric cancer and early gastric cancer were 0.80% (64/8 000) and 43.75% (28/64), respectively. The proportion of early gastric cancer+HGIN who received endoscopic submucosal dissection (ESD) was 77.78% (70/90), and the rate of curative resection was 100.00%(70/70). (2) Opportunistic screening: from July 2017 to December 2020, the annual early gastric cancer detection rates in opportunistic screening in Wendeng District Traditional Chinese and Western Medicine Hospital were 16.67% (1/6), 20.00% (3/15), 23.53% (4/17), and 33.33% (6/18) in the consecutive 4 years, respectively. The annual detection rates of early gastric cancer in opportunistic screening in Ru Shan Peoples Hospital were 14.74% (14/95), 23.80% (60/252), 25.49% (65/255), and 24.04% (50/208), respectively. The detection rates of opportunistic screening for early gastric cancer in hospitals in Weihai city increased year by year.Conclusion:In areas with high incidence of gastric cancer, a certain scale of group screening can lead to a wider range of opportunistic screening, resulting in the increase of the detection rate of early gastric cancer. The new model of diagnosis and treatment of gastric cancer is worth recommendation.

Objective To investigate the recurrence of immune thrombocytopenia(ITP)in children and to establish a predictive model.Methods A total of 288 children with ITP admitted to Children's Hospital of Wujiang District and Children's Hospital Affiliated to Suzhou University from January 2018 to April 2022 were collected.The factors potentially related to the recurrence of ITP in children were screened.The children in the model group were divided into 2 groups according to the presence or absence of recurrence and the indicators of the 2 groups were compared.After screening the potential influencing factors by LASSO regression and the independent influencing factors of relapse in children with ITP patients by Logstic regression analysis,we constructed a column-line graph model by using R language and validated it.Results A total of 37(18.47%)of 201 patients in the model group experienced relapse.The age,blood type,duration of disease before treatment,antecedent infections,bleeding,initial treatment regimen,antinuclear antibody titer,initial count and mean platelet volume,initial platelet distri-bution width,initial peripheral blood lymphocyte count and time length to effective platelet count after treatment were found in the recurrence group versus the non-recurrence group The difference was statistically significant(P＜0.05).The results of multifactorial logistic regression analysis performed on the basis of LASSO regression showed that blood type,duration of illness before treatment,antecedent infection,initial treatment regimen,ini-tial peripheral blood lymphocyte count,and time to effective platelet count after treatment were independent influ-ences on the conversion of cough variant asthma to classic asthma in children.Based on the results of the multifac-torial analysis,a column chart model for predicting ITP recurrence in children was developed in R.The results of the receiver operating characteristic(ROC)analysis showed that the area under curve(AUC)of the column chart model for predicting ITP recurrence in children in the modeling group was 0.867[95%CI(0.796,0.938)]with a sensitivity of 84.2%and a specificity of 73.1%,and that in the validation group,the AUC was 0.838[95%CI(0.765),0.911]with a sensitivity of 82.3%and a specificity of 78.4%,0.911)]sensitivity was 82.3%and specificity was 78.4%.The Bootstrap method was used to repeat the sampling 1000 times,and the validation group was used for validation.The results of the calibration curve showed that the prediction curves of the model group and the validation group were basically fitted with the standard curve,suggesting that the model prediction accuracy was high.The results of the decision curve analysis of the model group showed that the net benefit rate of patients was greater than zero when the probability threshold of the column line graph model of pre-dicting ITP recurrence in children was 0.15-0.75.Conclusions ITP recurrence in children is mainly affected by the patient's age,blood type,and pre-treatment course of the disease,and the column-line diagram model based on these factors has a high accuracy and differentiation for ITP recurrence in parenting children.

OBJECTIVE： To provide reference for strengthening the construction of retail pharmacy pharmacists and ensure safe and rational use of drugs.  METHODS： A simple random sampling method was used to determine 18 cities （counties） in Guizhou province as survey sites to visits all retail drugstores one by one. According to the Pharmacist Pharmaceutical Care Competency Evaluation Standard（Trail） issued by the Chinese Pharmacists Association， questionnaire survey and face-to-face interviews were conducted with licensed pharmacists in Guizhou province’s retail pharmacies， and multiple linear regressions were conducted on the factors affecting the pharmacy’s pharmaceutical care competency.  RESULTS： A total of 943 retail pharmacies in Guizhou province were visited， and 270 licensed pharmacists were investigated. The total self-assessment score of pharmaceutical care competence was （79.62±11.23）， with 11.5％ of undergraduate education and above， and 53.0％ of pharmacy related majors. Among self-assessment score of pharmaceutical care competency， score of basic knowledge item such as foreign language knowledge， statistical knowledge and computer knowledge was the lowest， followed by clinical thinking ability and drug treatment evaluation ability. The results of multiple linear regression showed that age had significant influence on the scores of basic skills and professional knowledge. The influence of academic qualifications on personal accomplishment， basic knowledge， basic skills， professional knowledge and professional skills score was statistically significant； the influence of professional and technical positions on total score， personal accomplishment， basic skills and professional skills score was statistically significant （P＜0.05）. CONCLUSIONS： The overall educational level of licensed pharmacists in Guizhou retail pharmacies is low and their professional level is limited. It is suggested that the supervision of licensed pharmacists should be strengthened and the access conditions of licensed pharmacists should be improved； the education and training of professional competency of licensed pharmacists in pharmaceutical care should be strengthened， the functional orientation of licensed pharmacists in retail pharmacies should be clarified， and public safety and rational drug use should be effectively guaranteed.
