OBJECTIVE: To investigate the impact of early antimicrobial therapy on the prognosis of patients with suspected sepsis in emergency and outpatient settings. METHODS: A prospective cohort study was conducted. Patients with suspected sepsis admitted to the emergency department of Taizhou Hospital, Zhejiang Province, from May 1, 2022, to July 31, 2023, were enrolled. Participants were divided into an early group (0-1 hour) and a delayed group (> 1 hour) according to duration from admission to antimicrobial administration. General information, initial vital signs, laboratory parameters within 24 hours after admission, disease severity scores, vasoactive drug usage, and clinical outcomes of the patient were collected. Kaplan-Meier survival curve was used to analyze 28-day survival. Multivariate Cox proportional hazards regression was performed to identify independent risk factors for prognosis of the patients with suspected sepsis in emergency and outpatient settings. Sensitivity analyses were conducted through subgroup analyses. RESULTS: A total of 143 patients with suspected sepsis were enrolled in the analysis, with 66 patients in the early group and 77 in the delayed group. No statistically significant differences were observed in baseline characteristics (age, gender, vital signs, laboratory parameters, disease severity scores) or clinical outcomes [vasoactive drug usage rate, mechanical ventilation duration, length of intensive care unit (ICU) stay, total hospitalization duration] between the two groups. The 28-day mortality, multidrug resistance rate and sepsis confirmation rate did not differ significantly between the early group and delay group [28-day mortality: 18.2% (12/66) vs. 20.8% (16/77), multidrug resistance rate: 3.0% (2/66) vs. 2.6% (2/77), sepsis confirmation rate: 87.9% (58/66) vs. 88.3% (68/77), all P > 0.05]. Kaplan-Meier survival curve analysis showed no difference in 28-day cumulative survival between the two groups (Log-Rank test: χ² = 2.528, P = 0.112). Multivariate Cox proportional hazards regression identified vasoactive drug usage [hazard ration (HR) = 2.465, 95% confidence interval (95%CI) was 1.019-5.961, P = 0.045] and endotracheal intubation (HR = 5.516, 95%CI was 2.195-13.858, P < 0.001) as independent risk factors for 28-day death of the patients with suspected sepsis in emergency and outpatient settings. Further exploration of the impact of early antimicrobial therapy on 28-day death in different subgroups of the patients with suspected sepsis in emergency and outpatient settings was conducted through subgroup analysis. The results showed that in the patients with different ages (< 60 years old: HR = 1.214, 95%CI was 0.535-2.751, P = 0.643; ≥ 60 years old: HR = 2.085, 95%CI was 0.233-18.668, P = 0.511), sequential organ failure assessment (SOFA) scores (< 6: HR = 1.411, 95%CI was 0.482-4.128, P = 0.530; ≥ 6: HR = 0.869, 95%CI was 0.292-2.587, P = 0.801), shock indexes (< 1: HR = 1.095, 95%CI was 0.390-3.077, P = 0.863; ≥ 1: HR = 1.364, 95%CI was 0.458-4.059, P = 0.577) and whether diagnosed with sepsis or not (yes: HR = 0.943, 95%CI was 0.059-15.091, P = 0.967; no: HR = 1.207, 95%CI was 0.554-2.628, P = 0.636) subgroups, early usage of antibiotics had not shown any advantage in improving prognosis compared with delayed usage. CONCLUSION Early antimicrobial therapy does not improve the prognosis of patients with suspected sepsis in emergency and outpatient settings.

Objective:To investigate the prognosis of patients with initially resectable gastric cancer liver metastasis (GCLM) who were treated by different modalities, and analyze the influencing factors for prognosis of patients.Methods:The retrospective cohort study was conducted. The clinicopathological data of 327 patients with initially resectable GCLM who were included in the database of a nationwide multicenter retrospective cohort study on GCLM based on real-world data from January 2010 to December 2019 were collected. There were 267 males and 60 females, aged 61(54,68)years. According to the specific situations of patients, treatment modalities included radical surgery combined with systemic treatment, palliative surgery combined with systemic treatment, and systemic treatment alone. Observation indicators: (1) clinical characteristics of patients who were treated by different modalities; (2) prognostic outcomes of patients who were treated by different modalities; (3) analysis of influencing factors for prognosis of patients with initially resectable GCLM; (4) screening of potential beneficiaries in patients who were treated by radical surgery plus systemic treatment and patients who were treated by palliative surgery plus systemic treatment. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the independent sample t test. Measurement data with skewed distribution were represented as M( Q1, Q3), and comparison between groups was conducted using the rank sum test. Count data were described as absolute numbers or percentages, and comparison between groups was conducted using the chi-square test. The Kaplan-Meier method was used to calculate survival rate and draw survival curve, and Log-Rank test was used for survival analysis. Univariate and multivariate analyses were conducted using the COX proportional hazard regression model. The propensity score matching was employed by the 1:1 nearest neighbor matching method with a caliper value of 0.1. The forest plots were utilized to evaluate potential benefits of diverse surgical combined with systemic treatments within the population. Results:(1) Clinical characteristics of patients who were treated by different modalities. Of 327 patients, there were 118 cases undergoing radical surgery plus systemic treatment, 164 cases undergoing palliative surgery plus systemic treatment, and 45 cases undergoing systemic treatment alone. There were significant differences in smoking, drinking, site of primary gastric tumor, diameter of primary gastric tumor, site of liver metastasis, and metastatic interval among the three groups of patients ( P<0.05). (2) Prognostic outcomes of patients who were treated by different modalities. The median overall survival time of the 327 pati-ents was 19.9 months (95% confidence interval as 14.9-24.9 months), with 1-, 3-year overall survival rate of 61.3%, 32.7%, respectively. The 1-year overall survival rates of patients undergoing radical surgery plus systemic treatment, palliative surgery plus systemic treatment and systemic treatment alone were 68.3%, 63.1%, 30.6%, and the 3-year overall survival rates were 41.1%, 29.9%, 11.9%, showing a significant difference in overall survival rate among the three groups of patients ( χ2=19.46, P<0.05). Results of further analysis showed that there was a significant difference in overall survival rate between patients undergoing radical surgery plus systemic treatment and patients undergoing systemic treatment alone ( hazard ratio=0.40, 95% confidence interval as 0.26-0.61, P<0.05), between patients undergoing palliative surgery plus systemic treatment and patients under-going systemic treatment alone ( hazard ratio=0.47, 95% confidence interval as 0.32-0.71, P<0.05). (3) Analysis of influencing factors for prognosis of patients with initially resectable GCLM. Results of multivariate analysis showed that the larger primary gastric tumor, poorly differentiated tumor, larger liver metastasis, multiple hepatic metastases were independent risk factors for prognosis of patients with initially resectable GCLM ( hazard ratio=1.20, 1.70, 1.20, 2.06, 95% confidence interval as 1.14-1.27, 1.25-2.31, 1.04-1.42, 1.45-2.92, P<0.05) and immunotherapy or targeted therapy, the treatment modality of radical or palliative surgery plus systemic therapy were independent protective factors for prognosis of patients with initially resectable GCLM ( hazard ratio=0.60, 0.39, 0.46, 95% confidence interval as 0.42-0.87, 0.25-0.60, 0.30-0.70, P<0.05). (4) Screening of potentinal beneficiaries in patients who were treated by radical surgery plus systemic treatment and patients who were treated by palliative surgery plus systemic treatment. Results of forest plots analysis showed that for patients with high-moderate differentiated GCLM and patients with liver metastasis located in the left liver, the overall survival rate of patients undergoing radical surgery plus systemic treatment was better than patients undergoing palliative surgery plus systemic treatment ( hazard ratio=0.21, 0.42, 95% confidence interval as 0.09-0.48, 0.23-0.78, P<0.05). Conclusions:Compared to systemic therapy alone, both radical and palliative surgery plus systemic therapy can improve the pro-gnosis of patients with initially resectable GCLM. The larger primary gastric tumor, poorly differen-tiated tumor, larger liver metastasis, multiple hepatic metastases are independent risk factors for prognosis of patients with initial resectable GCLM and immunotherapy or targeted therapy, the treatment modality of radical or palliative surgery plus systemic therapy are independent protective factors for prognosis of patients with initially resectable GCLM.

Objective:To evaluate the application effect of a new type of laparoscopic multi-degree-of-freedom surgical instrument in the training of basic surgical skills and analyze the learning curve.Methods:The teaching records of the trainees who received training in the training base of laparoscopic surgeons in Chinese People′s Liberation Army General Hospital from January to October, 2023 were collected. The 50 trainees were randomly divided into conventional instrumentation group and new instrumentation group with 25 trainees in each group according to the random number table method before the training. According to the research design, five modules such as "accurate bean clamping, plum blossom pile bean clamping, ferrule positioning, threading with both hands, sewing and knotting" were trained. After the training, they were assessed and the completion time of each module was recorded. The comparison of the changes of the completion time of the two groups of students before and after training was statistically analyzed by differences-in-differences(DID) method, and the fitting analysis of learning curve was analyzed by cumulative summation method .Results:Before the training, there was no statistically significant difference in the time required to complete five modules between the two groups of trainees (all P>0.05). After the training, the time to complete the five modules in both groups was reduced compared to before the training (accurate bean clamping: (63.7±9.3) seconds vs. (85.4±18.2) seconds, t=2.38, P=0.035; plum blossom pile bean clamping: (45.2±6.8) seconds vs. (103.1±57.2) seconds, t=8.77, P=0.047; ring positioning: (78.5±19.1) seconds vs. (126.2±26.3) seconds, t=6.96, P=0.019; threading with both hands: (63.3±21.2) seconds vs. (105.8±27.9) seconds, t=3.43, P=0.015; sewing and knotting: (160.2±79.5) seconds vs. (228.9±96.6) seconds, t=4.58, P=0.008).The average time required to complete the five modules was shorter in the new instrument group compared to the conventional instrument group (DID for accurate bean clamping=37.66, t=2.43, P=0.007; DID for plum blossom pile bean clamping=58.42, t=3.03, P=0.013; DID for ferrule positioning=28.33, t=2.83, P=0.031; DID for threading with both hands=48.89, t=2.10, P=0.042; DID for sewing and knotting=54.78, t=3.57, P=0.012). In the learning curves for the plum blossom pile bean clamping, ferrule positioning, and sewing and knotting modules, the new instrument group required fewer class hours to reach proficiency compared to the conventional instrument group (plum blossom pile bean clamping: 3 class hours vs. 4 class hours; ferrule positioning: 4 class hours vs. 5 class hours; sewing and knotting: 3 class hours vs. 5 class hours). In the accurate bean clamping and threading with both hands modules, both the conventional and new instrument groups crossed the learning curve at the 5 th class hour, but there was a statistically significant difference in the slopes of the curves between the two groups (accurate bean clamping: t=-2.85, P=0.004; threading with both hands: t=-2.66, P=0.008). Conclusion:The new type of laparoscopic multi-degree-of-freedom surgical instruments can improve the learning effect and shorten the learning curve in laparoscopic training teaching, which shows good application effect and has the possibility of clinical trial.

AIM: To analyze and screen influencing factors of diabetic patients complicated with retinopathy, and establish and validate prediction model of nomogram.METHODS: A total of 1 252 patients from the Diabetes Complications Early Warning Dataset of the National Population Health Data Archive(PHDA)between January 2013 to January 2021 were selected and randomly divided into a modeling group(n=941)and a validation group(n=311). Univariate analysis, LASSO regression and Logistic regression analysis were used to screen out the influencing factors of diabetic retinopathy, and a nomogram prediction model was established. The receiver operating characteristic curve, Hosmer-Lemeshow test and calibration curve were used to evaluate the model. The clinical benefit was evaluated by the decision curve analysis(DCA).RESULTS: Age, hypertension, nephropathy, systolic blood pressure(SBP), glycated hemoglobin(HbA1c), high-density lipoprotein cholesterol(HDL-C), and blood urea(BU)were the influencing factors of diabetic retinopathy. The area under the curve(AUC)of the modeling group was 0.792(95%CI: 0.763-0.821), and the AUC of the validation group was 0.769(95%CI: 0.716-0.822). The Hosmer-Lemeshow goodness of fit test and calibration curve suggested that the theoretical value of the model was in good agreement(modeling group: χ2=14.520, P=0.069; validation group: χ2=14.400, P=0.072). The DCA results showed that the threshold probabilities range was 0.09-0.89 for modeling group and 0.07-0.84 for the validation group, which suggested the clinical net benefit was higher.CONCLUSION: This study constructed a risk prediction model including age, hypertension, nephropathy, SBP, HbA1c, HDL-C, and BU. The model has a high discrimination and consistency, and can be used to predict the risk of diabetic retinopathy in patients with diabetes.

Postoperative sarcopenia was detected in 81 (21.7%) patients in the entire cohort. The SMI for the entire group was (41.79±7.70) cm 2/m 2: (46.40±5.03) cm 2/m 2 for men and (33.52±3.63) cm 2/m 2 for women. According to multivariate logistic regression analysis, age ≥60 years (OR=2.170, 95%CI: 1.175-4.007, P=0.013), high literacy (OR=2.512, 95%CI: 1.238-5.093, P=0.011), poor exercise habits (OR=3.263, 95%CI: 1.648-6.458, P=0.001), development of hypoproteinemia (OR=2.312, 95%CI: 1.088–4.913, P=0.029), development of hypertension (OR=2.169, 95%CI: 1.180-3.984, P=0.013), and total gastrectomy (OR=2.444, 95%CI:1.214-4.013, P=0.012) were independent risk factors for postoperative sarcopenia in post-gastrectomy patients who had had gastric cancer ( P<0.05). Conclusion:Development of sarcopenia following radical gastrectomy demands attention. Older age, higher education, poor exercise habits, hypoproteinemia, hypertension, and total gastrectomy are risk factors for its development post-radical gastrectomy.

Objective To explore the effect of training mode based on action learning on improving the practicing ability of hospital pharmacists.Methods Thirty pharmacists who received training from September 2022 to December 2023 at Panzhihua Central Hospital were randomly divided into an education reform group(16 cases)and a routine group(14 cases).The education reform group adopted a routine teaching method based on action learning,while the routine group adopted a routine teaching method.The differences between the two groups of pharmacists in theoretical knowledge,practical operation,pharmaceutical services,emergency response,and comprehensive quality were compared.Results The pharmacists in the education reform group were better than the routine group in prescription review,clinical medication analysis,pharmaceutical services,emergency response,andcomprehensive quality.The difference was statistically significant(P＜0.05).Conclusion The teaching model based on action learning can effectively enhance the higher order thinking ability of pharmacists and help them better apply medical knowledge and skills to serve patients and physicians.

Objective:To investigate the impact of proximal versus total gastrectomy on survival outcomes in patients with advanced upper gastric cancer following neoadjuvant therapy, aiming to provide evidence-based guidance for optimal surgical approach selection.Methods:A retrospective cohort study was conducted to collect clinical data from 114 patients with upper gastric cancer who underwent surgical treatment after neoadjuvant therapy in the PLA General Hospital between November 2014 and November 2023, consisting of 96 males and 18 females, with an age range of 41 to 78 years and a median age of 64 years. According to the extent of surgical resection, 44 patients underwent proximal gastrectomy (PG), and 70 patients underwent total gastrectomy (TG). Propensity score matching was used to match patients with advanced upper gastric cancer who received proximal gastrectomy or total gastrectomy after neoadjuvant therapy based on factors such as gender, age, surgical approach, BMI, ypT stage, ypN stage, tumor size, R0 resection status, neoadjuvant therapy cycles, and neoadjuvant therapy regimen, with a 1∶1 matching ratio. In the end, 44 patients in the PG group and 44 patients in the TG group were successfully matched and analyzed. The primary outcomes were overall survival (OS) and disease-free survival (DFS), while secondary outcomes included operative duration, R0 resection rate, complication rate, total number of lymph nodes dissected, number of lymph nodes dissected in each group, and lymph node metastasis rate. Data analysis was performed using SPSS 25.0, and survival curves were generated using the Kaplan-Meier (K-M) method.Results:After propensity score matching, the operative time in the TG group was significantly longer than that in the PG group [(222.0±42.5) min vs (257.0±62.0) min, χ2=3.07, P=0.003], while the differences in other baseline characteristics between the two groups were not statistically significant ( P>0.05). In terms of postoperative complications, the incidence of Clavien-Dindo grade II or higher complications was 29.5% in the PG group and 34.1% in the TG group ( P=0.819), indicating no significant difference. The 5-year overall survival (OS) rates were 55.8% for the PG group and 49.5% for the TG group ( P=0.592), showing no statistically significant difference. Lymph node metastasis rates in the TG group were 5.71% (4/70) in group 4d, 4.29% (3/70) in group 5, 2.86% (2/70) in group 6, and 2.86% (2/70) in group 12a. Conclusions:For patients with advanced upper gastric cancer who undergo proximal gastrectomy or total gastrectomy following neoadjuvant therapy, there is no significant difference in perioperative complications and long-term survival rates. Therefore, proximal gastrectomy is a safe and reliable option for these patients, allowing partial preservation of gastric function and potentially improving quality of life.

Objective:To investigate the risk factors for postoperative complications in emergency surgery for traumatic colon injury.Methods:In this study, a retrospective cohort study was used to collect the case data of 59 patients diagnosed with traumatic colon injury and emergency surgery in the PLA General Hospital from March 1, 2011 to March 31, 2023. According to whether complications occurred after emergency surgery, the patients were divided into the complication group( n=30)and the non-complication group( n=29). The main observation indexes were complication rate, Clavien-Dindo classification of complications, and risk factors related to complications. Normally distributed measurements were expressed as mean±standard deviation( ± s), and t-test was used for comparison between groups. Count data were compared between groups using the chi-square test. Clinically significant risk factors for predicting the occurrence of postoperative complications were determined by univariate and using multivariate logistic regression analysis. Results:A total of 56 occurrences of complications in 30 cases. 15 cases had multiple complications. Clavien-Dindo classification consisted of 23 cases of grade Ⅱ(41.1%), 1 cases of grade Ⅲa(1.8%), 6 cases of grade Ⅲb(10.7%), and 1 case of grade V(1.8%). The top three complication rates were 16 cases(28.6%) of pneumonia and(or) pleural effusion, 12 cases(21.4%) of incision infection, and 9 cases(16.1%) of postoperative bleeding. Univariate analysis showed that body mass index<24 kg/m 2, operation duration>235 min, intraoperative blood loss>100 mL, AAST-OIS grade≥4, preoperative serum albumin<35 g/L, preoperative white blood cell count>10×10 9/L, and preoperative procalcitonin≥2 ng/mL were risk factors for postoperative complications in traumatic colon injury underwent emergency surgery( P<0.05). Multivariate logistic regression analysis showed that body mass index<24 kg/m 2( OR=144.047, 95% CI: 3.695-5 614.986, P=0.008), preoperative serum albumin <35 g/L( OR=116.430, 95% CI: 3.582-3 784.038, P=0.007), preoperative procalcitonin≥2 ng/mL( OR=13.412, 95% CI: 1.030-174.662, P=0.047), and AAST-OIS grade≥4( OR=134.509, 95% CI: 3.934-4 599.473, P=0.007) were risk factors for postoperative complications in traumatic colon injury underwent emergency surgery. Conclusion:body mass index<24 kg/m 2, preoperative serum albumin<35 g/L, preoperative procalcitonin>2 ng/mL and AAST-OIS grade≥4 are risk factors for postoperative complications of traumatic colon injury. Early targeted treatment for patients with risk factors can help improve prognosis.
