OBJECTIVE To investigate the effects of esketamine for multimodal analgesia on opioid consumption and gastric motility in mechanically ventilated non-surgical intensive care unit （ICU） patients. METHODS Forty cases of mechanically ventilated non-surgical patients in the ICU of our hospital from February 1st， 2023 to July 31st， 2023 were selected and randomly divided into control group and esketamine （S-K） group using grouping method with opaque envelopes， with 20 cases in each group. Control group was given sufentanil， and S-K group was infused with Esketamine hydrochloride injection at a constant rate of 0.2 mg/（kg·h）+ sufentanil. The treatment period length， analgesic compliance rate， sedation level， analgesic and sedative consumption， and gastric motility indexes were compared between the two groups. RESULTS There was no statistically significant difference in the treatment period length， analgesic compliance rate， sedation level， or the consumption of propofol and midazolam between the two groups （P＞0.05）. The consumption of sufentanil in the S-K group was significantly less than control group （P＜ 0.05）. Compared with 1 h after randomization， the antral contraction frequency， antral contraction amplitude and antral motility index of patients in the S-K group were significantly higher at 72 h after randomization and were significantly higher than control group （P＜0.05）. CONCLUSIONS Esketamine may reduce opioid consumption and improve gastric motility in mechanically ventilated non-surgical ICU patients while ensuring a level of analgesic sedation.

Osteoporotic proximal humeral fracture (OPHF) is one of the common osteoporotic fractures in the aged, with an incidence only lower than vertebral compression fracture, hip fracture, and distal radius fracture. OPHF, secondary to osteoporosis and characterized by poor bone quality, comminuted fracture pattern, slow healing, and severely impaired shoulder joint function, poses a big challenge to the current clinical diagnosis and treatment. In the field of diagnosis, treatment, and rehabilitation of OPHF, traditional Chinese and Western medicine have accumulated rich experience and evidence from evidence-based medicine and achieved favorable outcomes. However, there is still a lack of guidance from a relevant consensus as to how to integrate the advantages of the two medical systems and achieve the integrated diagnosis and treatment. To promote the diagnosis and treatment of OPHF with integrated traditional Chinese and Western medicine, relevant experts from Orthopedic Expert Committee of Geriatric Branch of Chinese Association of Gerontology and Geriatrics, Youth Osteoporosis Group of Orthopedic Branch of Chinese Medical Association, Osteoporosis Group of Orthopedic Surgeon Branch of Chinese Medical Doctor Association, and Osteoporosis Committee of Shanghai Association of Integrated Traditional Chinese and Western Medicine have been organized to formulate Expert consensus on the diagnosis and treatment of osteoporotic proximal humeral fracture with integrated traditional Chinese and Western medicine ( version 2024) by searching related literatures and based on the evidences from evidence-based medicine. This consensus consists of 13 recommendations about the diagnosis, treatment and rehabilitation of OPHF with integrated traditional Chinese medicine and Western medicine, aimed at standardizing, systematizing, and personalizing the diagnosis and treatment of OPHF with integrated traditional Chinse and Western medicine to improve the patients ′ function.

Laparoscopic distal pancreatectomy is the conventional treatment for tumors of the pancreatic body or tail.And laparoscopic spleen-preserving distal pancreatectomy has been emphasized because it can preserve the spleen's function and lower the complications following splenectomy.However,the occult onset and complex anatomical location of pancreatic tumors pose a challenge to their diagnosis and spleen-preserving distal pancreatectomy.In recent years,our team has accumulated rich experience in the diagnosis and treatment of pancreatic tumors,and innovatively proposed the"SELECT"concept(S-Single-Operator Cholangiopancreatoscopy,E-ERCP,L-Laparoscopy,E-Endoscopic ultrasound,C-Choledochoscopy/Confocal laser endomicroscopy,T-Traditional Chinese medicine)for diagnosis and treatment.Based on the various characteristics of pancreatic tumors,various endoscopic and laparoscopic techniques are applied,and an optimal combination of various minimally invasive methods is selected.Fully applying the SELECT concept to laparoscopic spleen-preserving distal pancreatectomy is conducive to accurate preoperative diagnosis,accurate intraoperative resection,prediction and treatment of postoperative complications,and one-stop diagnosis and treatment of pancreatic tumors,maximizing patient benefits.

Cholelithiasis is a common and frequent disease of the digestive system, and its incidence rate tends to increase with the improvement of living standards. Patients suffering from both gallbladder stones and common bile duct stones account for 5%-15%. Choledocholithiasis can cause a series of serious complications such as acute cholangitis and biliary pancreatitis. Choledocholithotomy is the main method for the treatment of choledocholithiasis, but there is still a high recurrence rate after surgery. The recurrence of choledocholithiasis seriously affects the life of patients and increases their economic burden. With reference to the latest published clinical studies, this article summarizes the influencing factors for the recurrence of choledocholithiasis from the aspects of anatomical factors, stone-related factors, biliary factors, and surgical factors, so as to provide a reference for the treatment of choledocholithiasis and the prevention of its recurrence.

Objective To explore the relationship between non-high density lipoprotein cholesterol(non-HDL-C)level and leptomeningeal collateral circulation in patients with acute middle cerebral artery occlusion.Methods A total of 85 patients with first-onset acute cerebral infarction with middle cerebral artery M1 segment occlusion were enrolled.According to the results of DSA,LMC circulation was assessed by American Society of Interventional and Therapeutic Neuroradiology/Society of Interventional Radiology Collateral Circulation Assess-ment System.All patients were assigned to better LMC circulation group(score 2～4,n = 30)and worse LMC circulation group(score 0～1,n = 55),and the levels of non-HDL-C were compared between the two groups.Results The levels of LDL-C and non-HDL-C in worse LMC circulation group were significantly higher than those of the better LMC circulation group(P = 0.026,P = 0.010).non-HDL-C was an independent risk factor for the worse LMC circulation(OR = 3.019,95%CI:1.053～8.658,P = 0.04).LMC circulatory score of patients was negatively correlated with the levels of non-HDL-C level(r =-0.228,P = 0.036).The AUC of non-HDL-C predicted for the worse LMC circulation was 0.638(95%CI:0.521～0.755,P = 0.036).Conclusions non-HDL-C in patients with acute cerebral infarction was significantly related to worse LMC circulation,and was a risk factor for worse LMC circulation.It is suggested that the higher expression of non-HDL-C could be used to predict worse LMC circulation as a serological indicator.

Intra-abdominal infection is the second common infectious disease in intensive care unit and inhospital patients, with the mortality rate of 20%-30%. Advances in medicine have not improved the outcomes of patients with intra-abdominal infection, and the increasing multi-drug resistance organism may lead to a deterioration in the prognosis of patients with intra-abdominal infection. Gut microbiota dysbiosis and abdominal cavity infections show an interdependent and mutually aggravating relationship. Intestinal microecological preparations regulate gut flora and are potential therapeutic measures for intra-abdominal infections. The authors review the changes in gut flora during intra-abdominal infection, the effect of gut flora on the prognosis of intra-abdominal infections and the role of intestinal microecological preparations in intra-abdominal infections.

Objective:To compare the early therapeutic effects of internal fixation with percutaneous minimally invasive hollow nail assisted by electromagnetic navigation robot and guided by C-arm in the treatment of Tile type C pelvic fracture.Methods:A retrospective cohort study was conducted to analyze the clinical data of 32 patients with Tile type C pelvic fracture admitted to Weihai Central Hospital from January 2020 to March 2022, including 18 males and 14 females; aged 36-60 years [(44.1±3.9)years]. Among them, 17 patients were treated with internal fixation with percutaneous minimally invasive hollow nail assisted by electromagnetic navigation robot (electromagnetic navigation group), and 15 with internal fixation with percutaneous minimally invasive hollow nail guided by C-arm (C-arm guidance group). Operative time, intraoperative blood loss, sacroiliac screw placement time, pubic branch screw placement time, ambulation time and fracture healing time were compared between the two groups. Visual analog scale (VAS), Majeed function score and complication rate at 1 day, 6 months, 12 months after surgery and at the last follow-up were compared between the two groups.Results:All the patients were followed up for 12-24 months [(15.4±0.5)months]. The operative time and intraoperative blood loss in the electromagnetic navigation group were (42.0±2.5)minutes and (10.9±2.6)ml, shorter or less than (50.0±3.5)minutes and (14.9±3.1)ml in the C-arm guidance group (all P<0.01). The placement time of sacroiliac screw and pubic branch screw in the electromagnetic navigation group was (12.4±0.2)minutes and (10.1±0.3)minutes, shorter than (15.3±0.3)minutes and (13.2±0.3)minutes in the C-arm guidance group (all P<0.01). The ambulation time was (3.2±0.4)weeks in the electromagnetic navigation group, earlier than (3.5±0.4)weeks in the C-arm guidance group ( P<0.05). There was no significant difference in fracture healing time between the two groups ( P>0.05). VAS scores of the electromagnetic navigation group were (4.4±0.3)points and (1.1±0.1)points at 1 day and 6 months after surgery respectively, lower than those of the C-arm guidance group [(4.8±0.4)points and (1.2±0.3)points] ( P<0.05 or 0.01). Majeed function scores of the electromagnetic navigation group were (37.3±1.1)points and (88.5±1.4)points at 1 day and 6 months after surgery respectively, higher than those of the C-arm guidance group [(30.7±4.2)points and (82.6±1.8)points] (all P<0.01). There were no significant differences in VAS and Majeed scores at 12 months after surgery and at the last follow-up between the two groups (all P>0.05). There was no significant difference in the incidence of postoperative complications between the two groups ( P>0.05). Conclusion:Compared with C-arm guidance, electromagnetic navigation robot-assisted internal fixation with percutaneous minimally invasive hollow nail for Tile type C pelvic fracture can reduce operative time and intraoperative blood loss, shorten screw placement time and ambulation time, relieve pain and improve functional recovery at early stage.

ObjectiveTo investigate the effect of Qingre Lidan granules in preventing the recurrence of choledocholithiasis after laparoscopy combined with choledochoscopy through a retrospective cohort study. MethodsA total of 337 inpatients with choledocholithiasis （including those with cholecystolithiasis at the same time） who underwent laparoscopy combined with choledochoscopic lithotomy in The First Affiliated Hospital of Dalian Medical University from January 1， 2010 to December 31， 2020 were enrolled， and related clinical data were collected. According to the follow－up results， the patients were divided into exposure group （conventional treatment+Qingre Lidan granules） with 225 patients and non－exposure group （conventional treatment） with 112 patients. The recurrence of choledocholithiasis and the administration of Qingre Lidan granules were recorded in detail for both groups. The recurrence rate of choledocholithiasis and the time to recurrence were observed for both groups， and the risk factors for the recurrence of choledocholithiasis were analyzed. The independent－samples t test was used for comparison of normally distributed continuous data between two groups， and the Mann－Whitney U test was used for comparison of non－normally distributed continuous data between two groups； the chi－square test or the Fisher’s exact test was used for comparison of categorical data between two groups. The Kaplan－Meier curve was used to estimate the cumulative probability of choledocholithiasis recurrence in the two groups， and the Log－rank test was used for comparison between two groups. ResultsA total of 26 patients experienced the recurrence of choledocholithiasis after laparoscopy combined with choledochoscopy， with 12 patients （5.33%） in the exposure group and 14 （12.5%） in the non－exposure group， and the exposure group had a significantly lower recurrence rate than the non－exposure group （χ²=5.394， P=0.020）. The exposure group had a significantly longer mean time to the recurrence of choledocholithiasis than the non－exposure group （40.1±26.7 months vs 19.2±13.5 months， t=2.383， P=0.017）. The Kaplan－Meier curve analysis showed that the non－exposure group had a significantly higher cumulative recurrence rate than the exposure group in different periods of time （P<0.05）. The multivariate logistic regression analysis showed that common bile duct diameter ≥14 mm （odds ratio 〔OR〕=2.935， P=0.031） and multiple calculi （OR=2.911， P=0.029） were independent risk factors for the recurrence of choledocholithiasis after laparoscopy combined with choledochoscopic lithotomy. ConclusionQingre Lidan granules can effectively reduce the recurrence rate of choledocholithiasis and prolong the time to the recurrence of choledocholithiasis after laparoscopy combined with choledochoscopy and has a certain clinical effect in preventing the recurrence of choledocholithiasis after surgery.

Objective:To investigate the clinical characteristics and influencing factors of mortality in patients with intra-abdominal candidiasis (IAC).Methods:The retrospective case-control study was conducted. The clinicopathological data of 203 IAC patients who were admitted to 7 medical centers from June 2018 to June 2020 were collected, including 54 cases in Sir Run Run Shaw Hospital of Zhejiang University School of Medicine, 31 cases in Fujian Medical University Union Hospital, 25 cases in Beijing Hospital, 25 cases in the First Affiliated Hospital of Xi'an Jiaotong University, 24 cases in China-Japan Friendship Hospital, 22 cases in General Hospital of Eastern Theater Command of Chinese PLA and 22 cases in Chongqing University Cancer Hospital. There were 130 males and 73 females, aged (64±15)years. Observation indicators: (1) candida infection and treatment of IAC patients; (2) analysis of influencing factors for mortality of IAC patients. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was analyzed using the t test. Measurement data with skewed distribution were represented as M(range), and comparison between groups was analyzed using the Mann-Whitney U test. Count data were expressed as absolute numbers or percentages, and comparison between groups was analyzed using the chi-square test. Univariate and multivariate analyses were performed by Logistic regression model. Results:(1) Candida infection and treatment of IAC patients: 134 cases of candida albicans were cultured in the initial abdominal drainage fluid or intraoperative abdominal specimens of 203 patients, and 49 cases were treated with fluconazole. Of 69 cases infected with non candida albicans, 13 cases were treated with fluconazole. The resistance rate of candida albicans to fluconazole was 5.91%(12/203). Of 203 patients, there were 68 cases with infections shock, 53 cases with renal failure, 84 cases with respiratory failure and 63 cases with multiple organ failure, respectively. There were 148 of 203 patients admitted to intensive care unit for 9 days(range, 3-20 days), and the total hospital stay was 28 days(range, 17-50 days). Of 203 patients, 86 cases were cured and discharged, 50 cases were improved and transferred to local hospitals, 32 cases gave up treatment and discharged automatically, 19 cases died, 16 cases had no follow-up data. The mortality was 25.12%(51/203). (2) Analysis of influencing factors for mortality of IAC patients. Results of univariate analysis showed that acute physiology and chronic health evaluation score, sequential organ failure assessment score, the Cr, bilirubin, albumin, procalcitonin, and PLT on the first day of candida positive culture, of the lowest value in a week and the highest in a week, heart disease, diabetes, infections shock, renal failure, respiratory failure, multiple organ failure, anti-fungal therapy were the related factors for mortality of IAC patients ( t=-2.322, Z=-2.550, -2.262, -4.361, t=2.085, Z=-3.734, -5.226, -2.394, -5.542, t=3.462, Z=-4.957, -5.632, 3.670, -5.805, t=3.966, Z=-3.734, -5.727, χ2=4.071, 4.638, 27.353, 18.818, 13.199, 26.251, 13.388, P<0.05). Multivariate analysis showed that the bilirubin, procalcitonin on the first day of candida positive culture and infections shock were independent risk factors for mortality of IAC patients ( odds ratio=1.021, 1.022, 6.864, 95% confidence interval as 1.010-1.033, 1.001-1.044, 1.858-25.353, P<0.05). Conclusions:The common fungus of IAC was candida albicans, and fluconazole can be used as the initial empirical treatment. The prognosis of patients with abdominal candidiasis is poor. Bilirubin, procalcitonin on the first day of candida positive culture and infections shock are indepen-dent risk factors for mortality of IAC patients.
