Objective To investigate the Huatan Huoxue Jiangqi prescription in treating AECOPD clinical curative effect. Methods 123 patients with AECOPD were randomly divided into the treatment group and the control group. The two groups were treated with western medicine, and the treatment group added with Chinese herbal medicine treatment with Huatan Huoxue Jiangqi prescription. The syndrome effect, clinical symptom score, CAT score, mMRC classification, lung function, the serum FIB and CRP levels were obtained to evaluate the efficacy of the two groups before and after treatment. Results The syndrome effect of the treatment group was significantly better than that of the control group. Compared with the control group, there was significant difference between traditional Chinese medicine syndrome score, CAT score (P < 0.05); Lung function (including FEV1, FEV1%, FEV1/FVC) was significantly improved in the treatment group after treatment (P < 0.05). The serum FIB and CRP levels decreased significantly in the treatment group compared with the control group (P < 0.05). Conclusion Huatan Huoxue Jiangqi prescription has reliable effets on treating AECOPD.

Objective:To compare the perioperative outcomes of laparoscopic duodenal-preserving pancreatic head resection(LDPPHR) with laparoscopic pancreaticoduodenectomy(LPD) in the treatment of borderline and benign diseases of the pancreatic head.Methods:This is a retrospective cohort study. Perioperative data from 87 patients with non-malignant pancreatic head diseases who underwent LDPPHR or LPD were retrospectively collected in the Department of Biliary-Pancreatic Surgery,Tongji Hospital,Tongji Medical College,Huazhong University of Science and Technology from January 2020 to December 2022. There were 49 male and 38 female patients with an age ( M(IQR)) of 57.0(16.5) years (range: 20 to 75 years). Forty patients underwent LDPPHR and 47 patients underwent LPD. Quantitative data following a normal distribution were compared using Student′s t-test, while quantitative data not following a normal distribution were compared using the Mann-Whitney U test. Comparisons of categorical or ordinal variables were made using χ2 test or Fisher′s exact test. Logistic regression analysis was used to estimate the risk factors associated with the rate of complications. Results:There were no statistically significant differences between the LDPPHR group and the LPD group in terms of reoperation rate,total hospital stay duration,postoperative hospital stay duration,90-day mortality rate,30-day and 90-day readmission rates,and 2-year tumor recurrence rate (all P>0.05). The complication rate was higher in the LDPPHR group compared to the LPD group (80.0%(32/40) vs. 51.1%(24/47), χ2=7.89, P=0.005),but there was no difference in the rate of Clavien-Dindo classification of surgical complications ≥Ⅲ between the two groups (10.0%(4/40) vs. 12.8%(6/47), χ2<0.01, P=0.947). Additionally,the rate of delayed gastric emptying (DGE) was higher in the LDPPHR group compared to the LPD group ( χ2=10.79, P=0.001),but there was no statistically significant difference in the rate of B,C grade DGE between the two groups ( χ2=0.48, P=0.487). There were no statistically significant differences in the rates of postoperative pancreatic fistula,bile leakage,post-pancreatectomy hemorrhage,intra-abdominal infection,and pulmonary infection between the two groups (all P>0.05). The results of the univariate logistic regression analysis showed that LDPPHR (compared to LPD, OR=3.83, 95% CI: 1.46 to 10.04, Z=2.73, P=0.006) and preoperative biliary stent placement (compared to non-use of biliary stent, OR=5.30, 95% CI: 1.13 to 25.00, Z=2.11, P=0.035) were risk factors for the complication rate,but neither was an independent risk factor for complication rate (all P>0.05). Conclusion:The preliminary results suggest that LDPPHR can achieve perioperative safety and effectiveness comparable to LPD.

Objective:To investigate the feasibility and safety of laparoscopic radical resection of hilar cholangiocarcinoma at multiple centers in China.Methods:Between December 2015 and August 2019, the clinical data of 143 patients who underwent LRHC in Affiliated Hospital of North Sichuan Medical College, Second Hospital of Hebei Medical University, Affiliated Hospital of Xuzhou Medical University, Affiliated Tongji Hospital of Tongji Medical College, Huazhong University of Science and Technology, Hunan Provincial People′s Hospital, the First Hospital Affiliated to Army Medical University, Sir Run Run Shaw Hospital Affiliated to Medical College of Zhejiang University, West China Hospital of Sichuan University, Nanfang Hospital of Southern Medical University and the First Affiliated Hospital of Chongqing Medical University were collected prospectively. There were 92 males and 51 females with age of (64±11) years (range: 53 to 72 years). Bismuth type: type I, 38 cases (26.6%), type Ⅱ, 19 cases (13.3%), type Ⅲa, 15 cases (10.5%), type Ⅲb, 28 cases (19.6%) and type Ⅳ, 43 cases (30.0%). The patients within the first 10 operation cases in each operation time (the first 10 patients in each operation team) were divided into group A (77 cases), and the patients after 10 cases in each operation time were classified as group B (66 cases); the cases with more than 10 cases in the center were further divided into group A 1 (116 cases), and the center with less than 10 cases was set as group A 2 (27 cases). T test or Wilcoxon test was used to compare the measurement data between groups, and the chi square test or Fisher exact probability method was used to compare the counting data between groups. Kaplan Meier curve was used for survival analysis. Results:All patients successfully completed laparoscopic procedure. The mean operation time was (421.3±153.4) minutes (range: 159 to 770 minutes), and the intraoperative blood loss was 100 to 1 500 ml (median was 300 ml) .Recent post-operative complications contained bile leakage, abdominal bleeding, abdominal infection, gastrointestinal bleeding, and delay gastric emptying, pulmonary infection, liver failure, et al.The post-operative hospital stay was (15.9±9.2) days. The operation time in group B was relatively reduced ( (429.5±190.7)minutes vs. (492.3±173.1)minutes, t=2.063, P=0.041) and the blood loss (465 ml vs. 200 ml) was also reduced ( Z=2.021, P=0.043) than that in group B. The incidence of postoperative biliary fistula and lung infection in patients in group A was significantly higher than that in group B (χ 2=4.341, 0.007; P=0.037, 0.047) .Compared with group A 2, the operation time in group A 1 was relatively reduced( (416.3±176.5)minutes vs. (498.1±190.4)minutes, t=2.136, P=0.034) , the incidence of bile leakage and abdominal cavity infection in group A 1 was lower than that in group A 2 (χ 2=7.537, 3.162; P=0.006, 0.046) . Kaplan Meier survival curve showed that the difference of short-term survival time between group A and group B was statistically significant ( P<0.05) . Conclusions:The completion of laparoscopic hilar cholangiocarcinoma radical surgery is based on improved surgical skills, and proficiency in standardized operation procedures.It is feasible for laparoscopic radical resection of hilar cholangiocarcinoma to well experienced surgeon with cases be strictly screened, but it is not recommended for widespread promotion at this exploratory stage.

Objective:To explore the effect of action research in first aid skills training for nurses in Pediatric Clinic.Methods:This study was a own control study. From March to August 2020, convenience sampling was used to select 28 nurses from the Pediatric Clinic of the West China Second University Hospital, Sichuan University as the research subject. The first aid skills training for nurses was optimized through the spiral cycle process of "plan-action-observation-reflection" using action research. Before the training, after the first cycle, and after the second cycle, the self-designed First Aid Skills Assessment and Training Satisfaction Evaluation Scale was used, combined with the results of semi-structured interviews, to evaluate the first aid skills and training satisfaction of nurses in Pediatric Clinic before and after the program improvement.Results:Before training, in the first cycle, and in the second cycle, the nurses' first aid theory (except resuscitation balloon usage dimension) , first aid operation scores and satisfaction scores were compared, and the differences were statistically significant ( P<0.05) . Conclusions:The systematic training of first aid knowledge and operation for nurses in Pediatric Clinic by action research can effectively improve nurses' first aid skills and training satisfaction.
