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.

Objective To observe the clinical efficacy of acupuncture combined with rehabilitation training under the guidance of Chinese medicine-enhanced recovery after surgery(CMERAS)in postoperative rehabilitation of tibial plateau fracture.Methods Sixty patients with tibial plateau fracture in postoperative rehabilitation period were randomly divided into observation group and control group,30 cases in each group.The control group was given routine postoperative rehabilitation training,and the observation group was treated with combined acupuncture treatment on the basis of the rehabilitation training of the control group.Both groups were treated for 3 consecutive months.After 3 months of treatment,the clinical efficacy of the two groups was evaluated,and the changes in the Visual Analogue Scale(VAS)scores of pain were observed before and after treatment,and the changes in the knee scores of the Hospital for Special Surgery knee score(HSS)of the United States were compared before and after treatment between the two groups.As well as the time of fracture healing on the operative side of the two groups of patients,and the fracture healing rate within 3 months of the two groups of patients were compared.Results(1)After 1 week,1 month and 3 months of postoperative treatment,the VAS scores of patients in the two groups were significantly improved compared with the pre-treatment period(P＜0.05),and the observation group was significantly superior to the control group in improving the VAS scores,with a statistically significant difference(P＜0.05).(2)After treatment,the HSS scores of patients in the two groups were significantly improved compared with those before treatment(P＜0.05),and the observation group was significantly superior to the control group in improving the HSS scores,and the difference was statistically significant(P＜0.05).(3)After 3 months of treatment,the fracture healing rate was 56.67%(17/30)in the observation group and 30.00%(9/30)in the control group.The fracture healing rate of the observation group was superior to that of the control group,and the difference was statistically significant(P＜0.05).(4)After 3 months of acupuncture treatment,the total effective rate was 96.67%(29/30)in the observation group and 73.33%(22/30)in the control group.The efficacy of the observation group was superior to that of the control group,and the difference was statistically significant(P＜0.05).Conclusion The clinical efficacy of acupuncture in postoperative rehabilitation of tibial plateau fractures under the guidance of CMERAS is significant,which reduces the clinical symptom of postoperative pain of the patients,shortens the healing time of fracture breaks,and significantly improves the patients'knee joint function.

Objective To explore the relationship and internal path between activities of daily living(ADL),sleep quality and mental health of community elderly people in Shanghai.Methods A questionnaire survey was conducted among community residents aged 60 years and older seeing doctors in community health care center of five streets in Shanghai during Sept to Dec,2021 using convenience sampling.Activities of Daily Living(ADL),Pittsburgh Sleep Quality Index(PSQI)and 10-item Kessler Psychological Distress Scale(K10)were adopted in the survey.Single factor analysis,correlation analysis and multiple linear regression were used to analyze the data.The effect relationship between the variables was tested using Bootstrap's mediated effects test.Results A total of 1 864 participants were included in the study.The average score was 15.53±4.47 for ADL,5.60±3.71 for PSQI and 15.50±6.28 for K10.The rate of ADL impairment,poor sleep quality,poor and very poor mental health of the elderly were 23.6%,27.3%,11.9%and 4.9%,respectively.ADL and sleep quality were all positively correlated with mental health(r=0.321,P＜0.001;r=0.466,P＜0.001);ADL was positively correlated with sleep quality(r=0.294,P＜0.001).Multiple linear results of factors influencing mental health showed that ADL(β= 0.457,95%CI:0.341-0.573),sleep quality(β =0.667,95%CI:0.598-0.737)and mental health were positively correlated(P＜0.001).Sleep quality partially mediated the relationship between ADL and mental health(95%CI:0.078-0.124)with an effect size of 33.0%.Conclusion Sleep quality is a mediator between ADL and mental health among community elderly people.Improving ADL and sleep quality may improve mental health in the population.

Objective To establish in vitro the small intestinal organoid culture system and to investigate the effect of lipopolysaccharide(LPS)on the growth of small intestinal organoids and the secretion of inflammatory factors.Methods In vitro,the small intestinal crypt cell mass of C57BL/6 mice was aseptically isolated,collected and embedded in organoid matrix.Under the support of complete medium,the small intestinal organoids with three-dimensional multi-leaf structure with small intestinal epithelioid structure were formed.The small intestinal organoids were subcultured after 5-7 d culture.On the third day after passage,the small intestinal organoids were randomly divided into different mass concentrations of LPS groups(0,150,175,200,225,250,275 and 300 mg/L).After 24 h and 48 h of LPS induction,morphological changes of small intestinal organoid growth and differentiation were observed.CCK-8 method was used to detect the effect of different time points and mass concentrations of LPS on the proliferative activity of small intestinal organoids after induction of inflammation.The effects of four different mass concentrations of LPS(0,175,200 and 225 mg/L)on expression levels of granulocyte-macrophage colony stimulating factor(GM-CSF),interleukin(IL)-1α,IL-6 and IL-10 in organoid culture supernatant at different times were detected by enzyme-linked immunosorbent assay(ELISA).Results The mouse small intestinal organoid culture system was preliminarily constructed.After different time and mass concentration of LPS induced inflammation of small intestinal organoids,it was observed by morphology that small intestinal organoids would have different degrees of expansion and apoptosis in lumen.The proliferation,differentiation and budding of damaged intestinal epithelial crypts or intestinal stem cells were also inhibited to varying degrees,indicating that the growth of small intestinal organoids would be limited to varying degrees after induced inflammation.The proliferation activity of small intestinal organoids decreased to varying degrees after 24 h and 48 h of LPS induction at 175-225 mg/L(P＜0.05),but the cell viability was still greater than 50%.The levels of IL-1α,IL-6 and GM-CSF partially increased after induction with 200 mg/L and 225 mg/L LPS for 24 h and 48 h(P＜0.05).The level of IL-10 decreased after induction with 200 mg/L LPS for 24 h and 48 h(P＜0.05).Conclusion In this study,a model of intestinal inflammatory injury in vitro induced by LPS with different mass concentrations and time points is preliminarily constructed,which provides a more reliable research platform for the mechanism research of intestinal diseases and the screening of effective drugs in the future.

Objective To detect the level of related indexes of energy metabolism in liver tissue of alcoholic liver disease(ALD)mice,and to explore the intervention effect of Gehua Jiejiu Dizhi Decoction.Methods Forty male C57BL/6J mice were randomly divided into the normal control group,the model group,the Gehua Jiejiu Dizhi Decoction high-dose group(4.94 g/kg),the Gehua Jiejiu Dizhi Decoction low-dose group(2.47 g/kg),and the resveratrol group(0.40 g/kg),with 8 mice in each group.Except the normal control group,the mice in other groups were fed with Lieber-DeCarli control liquid diet for five days,followed by Lieber-DeCarli alcohol liquid diet for ten days,and on the 16th day,the mice were given 31.5%alcohol solution through gavage to establish the ALD model.From the second day after modeling,the rats in the intervention groups were given the corresponding drugs by gavage once a day for nine consecutive days.Hematoxylin and eosin staining and oil red O staining were used to observe the liver steatosis in liver tissue.The activities of Na+K+-ATPase and Ca2+Mg2+-ATPase,and the contents of succinate dehydrogenase(SDH)and hepatic glycogen in liver tissue were detected using spectrophotometry.The contents of ATP,ADP,AMP,the AMP/ATP value,total adenosine pool(TAN)content,and energy charge(EC)in liver tissue were detected by reversed phase high performance liquid chromatography method.The mRNA expressions of NAD dependent deacetylase Sirtuin-1(SIRT1)and AMP-activated protein kinase(AMPK)α2 in liver tissue were detected by real-time PCR.The protein expressions of SIRT1,AMPKα2,and AMPKβ1 in liver tissue were detected by Western blotting.Results Compared with the normal control group,the model group mice showed significant hepatic steatosis,significantly decreased Ca2+Mg2+-ATPase activity and SDH content in liver tissue,significantly increased hepatic glycogen content,significantly decreased EC and AMP/ATP value,significantly increased ATP,ADP,AMP,and TAN content,significantly decreased mRNA expressions of SIRT1 and AMPKα2,significantly increased protein expression of AMPKβ1(P<0.05).Compared with the model group,the Gehua Jiejiu Dizhi Decoction high-and low-dose groups significantly reduced liver tissue steatosis,and the activity of Na+K+-ATPase in liver tissue was significantly reduced,the EC and the mRNA expressions of SIRT1 and AMPKα2 were increased(P<0.05);the activity of Ca2+Mg2+-ATPase,SDH and ATP contents were increased in the Gehua Jiejiu Dizhi Decoction low-dose group(P<0.05);the AMP/ATP value was increased in the Gehua Jiejiu Dizhi Decoction high-dose group(P<0.05);and the protein expression of SIRT1 was increased in the the Gehua Jiejiu Dizhi Decoction high-and low-dose groups and the resveratrol group(P<0.05);the protein expression of AMPKα2 in the Gehua Jiejiu Dizhi Decoction low-dose group and the resveratrol group was increased(P<0.05).Compared with the Gehua Jiejiu Dizhi Decoction high-dose group,the Gehua Jiejiu Dizhi Decoction low-dose group and the resveratrol group showed a significant increase in ATP,TAN contents,and EC in liver tissue,while the AMP/ATP value decreased(P<0.05);mRNA expressionin of AMPKα2 in the Gehua Jiejiu Dizhi Decoction low-dose group was decreased(P<0.05);and the protein expressions of SIRT1 and AMPKα2 in the resveratrol group were increased(P<0.05).Compared with the Gehua Jiejiu Dizhi Decoction low-dose group,the protein expression of AMPKβ1 was decreased in the resveratrol group(P<0.05).Conclusion The changes of energy metabolism caused by chronic alcohol intake may be related to the occurrence of ALD,and the intervention of Gehua Jiejiu Dizhi Decoction can improve the abnormal energy metabolism in the liver of ALD mice.

Objective:To explore whether the degree of skeletal muscle atrophy in obese individuals under the influence of colorectal cancer is more severe than that in non-obese individuals.Methods:The clinical data of patients who underwent radical resection of colorectal cancer in our department from Jul 2020 to Dec 2021 was collected. Sixty-four obese patients were included and 64 non-obese patients were matched according to propensity score. At the same time, 51 obese patients were collected from non-tumor patients and matched with 51 non-obese patients. The psoas muscle index (PMI) of included patients was analyzed and compared.Results:The PMI of patients with colorectal cancer was significantly lower than that of corresponding non-tumor patients, regardless of gender and body weight (both P<0.05). The PMI of obese patients with colorectal cancer was significantly lower than that of non-obese patients ( P<0.05). Conclusions:The impact of colorectal cancer on skeletal muscle atrophy in obese individuals is greater than that in normal weight individuals. Therefore, the skeletal muscle status of obese patients with colorectal cancer should be evaluated more comprehensively.

AIM:To investigate whether the expression of perilipin 2(PLIN2)in renal tubular cells could predict a decline in renal function in diabetic kidney disease(DKD)patients,and to explore the potential mechanisms in-volved in renal tubular cell injury induced by PLIN2 during the progression of DKD.METHODS:Control individuals(n=12)and DKD patients(n=51)were enrolled in this retrospective cohort study.Demographic and laboratory data were col-lected.A simplified linear mixed-effects model was applied to assess the estimated glomerular filtration rate(eGFR)slope.The relationship between PLIN2 and renal function decline in DKD patients was predicted by Spearman correlation analysis and a generalized linear model.BKS-db/db diabetic mice and streptozotocin-induced diabetic mice were used.Primary renal tubular cells were treated with glucose and transfected with small interfering RNA or plasmid.Western blot-ting and immunofluorescence staining were used to detect PLIN2 expression.Lipid droplets were stained with oil red O.The oxygen consumption rate(OCR)of mitochondria was measured using an extracellular flux analyser.RESULTS:The expression of PLIN2 was markedly higher in the tubules of DKD patients than in those of control subjects.After 24(12,39)months of follow-up,the eGFR slope of DKD patients was-7.42(-19.77,-2.09)mL/(min·1.73 m2·year).An in-crease in the baseline percentage of PLIN2-positive tubules was significantly associated with the eGFR slope during the fol-low-up period[hazard ratio(HR)=1.90,95%confidence interval(CI):1.00～3.58],indicating that tubular PLIN2 could predict a decrease in renal function in DKD patients.Both the accumulation of lipid droplets and the expression of PLIN2 were markedly greater in the tubules of diabetic mice than in those of control mice.Glucose treatment induced lipid droplet accumulation and PLIN2 expression in renal tubular cells.Knockdown of PLIN2 significantly alleviated glucose-in-duced lipid droplet accumulation,whereas PLIN2 overexpression aggravated glucose-induced lipid droplet accumulation.The decrease in mitochondrial OCR in renal tubular cells induced by glucose treatment was alleviated after PLIN2 knock-down.However,overexpression of PLIN2 directly decreased the mitochondrial OCR.CONCLUSION:The PLIN2 ex-pression in tubules predicts a decline in renal function in patients with DKD.The PLIN2 suppresses mitochondrial aerobic respiration and contributes to the accumulation of lipid droplets in renal tubular cells to promote the progression of DKD.

Objective:To investigate the influence of curative-intent resection with textbook outcomes of liver surgery (TOLS) on long-term prognosis of gallbladder carcinoma (GBC).Methods:The retrospective cohort study was conducted. The clinicopathological data of 824 patients with GBC in the national multicenter database of Biliary Surgery Group of Elite Group of Chinese Journal of Digestive Surgery, who were admitted to 15 medical centers from January 2014 to January 2021, were collected. There were 285 males and 539 females, aged (62±11)years. According to the evalua-tion criteria of TOLS, patients were divided into those who achieved TOLS and those who did not achieve TOLS. Measurement data with normal distribution were represented as Mean± SD, and com-parison 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 Mann-Whitney U test. Count data were described as absolute numbers, and comparison between groups was conducted using the chi-square test. Comparison of ordinal data were conduc-ted using the Mann-Whitney U test. The Kaplan-Meier method was used to calculate survival rate and draw survival curve, and the Log-rank test was used for survival analysis. The COX stepwise regression model with backward Wald method was used for univariate and multivariate analyses. Results:(1) Achievement of TOLS. Of the 824 patients undergoing curative-intent resection for GBC, there were 510 cases achieving TOLS and 314 cases not achieving TOLS. (2) Follow-up. Of the 824 patients undergoing curative-intent resection for GBC, after excluding 112 deaths within 90 days after discharge, 712 cases were included for the survival analysis. The median follow-up time, median overall survival time and 5-year overall survival rate of the 510 patients achieving TOLS were 22.1(11.4,30.1)months, 47.6(30.6,64.6)months and 47.5%. The median follow-up time, median overall survival time and 5-year overall survival rate of the 202 patients not achieving TOLS were 14.0(6.8,25.5)months, 24.3(20.0,28.6)months and 21.0%. There was a significant difference in overall survival between patients achieving TOLS and patients not achieving TOLS ( χ2=58.491, P<0.05). (3) Analysis of factors influencing prognosis of patients. Results of multivariate analysis showed that TOLS, carcinoembryonic antigen (CEA), CA19-9, poorly differentiation of tumor, T2 stage of eighth edition of American Joint Committee on Cancer (AJCC) staging, T3 and T4 stage of eighth edition of AJCC staging, N1 stage of the eighth edition of AJCC staging, N2 stage of the eighth edition of AJCC staging, adjuvant therapy were independent factors influencing overall survival time of patients undergoing curative-intent resection for GBC ( hazard ratio=0.452, 1.479, 1.373, 1.612, 1.455, 1.481, 1.835, 1.978, 0.538, 95% c onfidence interval as 0.352-0.581, 1.141-1.964, 1.052-1.791, 1.259-2.063, 1.102-1.920, 1.022-2.147, 1.380-2.441, 1.342-2.915, 0.382-0.758, P<0.05). Conclusion:Patients under-going curative-intent resection for GBC with TOLS can achieve better long-term prognosis.

Objective:To investigate the early clinical characteristics of elderly patients with severe burns and the risk factors on prognosis.Methods:This study was a retrospective case series study. Clinical data of 124 elderly patients with severe burns who met the inclusion criteria and were admitted to the 12 hospitals from January 2015 to December 2020 were collected, including 4 patients from the Fourth People's Hospital of Dalian, 5 patients from Fujian Medical University Union Hospital, 22 patients from Guangzhou Red Cross Hospital of Jinan University, 5 patients from Heilongjiang Provincial Hospital, 27 patients from the First Affiliated Hospital of Naval Medical University, 9 patients from the First Affiliated Hospital of Nanchang University, 10 patients from Affiliated Hospital of Nantong University, 9 patients from Tongren Hospital of Wuhan University & Wuhan Third Hospital, 12 patients from the 924 th Hospital of PLA, 6 patients from Zhangjiagang First People's Hospital, 4 patients from Taizhou Hospital of Zhejiang Province, and 11 patients from Zhengzhou First People's Hospital. The patients' overall clinical characteristics, such as gender, age, body mass index, total burn area, full-thickness burn area, inhalation injury, causative factors, whether combined with underlying medical diseases, and admission time after injury were recorded. According to the survival outcome within 28 days after injury, the patients were divided into survival group (89 cases) and death group (35 cases). The following data of patients were compared between the two groups, including the basic data and injuries (the same as the overall clinical characteristics ahead); the coagulation indexes within the first 24 hours of injury such as prothrombin time (PT), activated partial thromboplastin time (APTT), thrombin time, D-dimer, fibrinogen degradation product (FDP), international normalized ratio (INR), and fibrinogen; the blood routine indexes within the first 24 hours of injury such as white blood cell count, platelet count, neutrophil-to-lymphocyte ratio, monocyte count, red blood cell count, hemoglobin, and hematocrit; the organ function indexes within the first 24 hours of injury such as direct bilirubin, total bilirubin, urea, serum creatinine, aspartate aminotransferase, alanine aminotransferase, total protein, albumin, globulin, blood glucose, triglyceride, total cholesterol, alkaline phosphatase, creatine kinase, electrolyte indexes (potassium, sodium, chlorine, calcium, magnesium, and phosphorus in blood), uric acid, myoglobin, and brain natriuretic peptide; the infection and blood gas indexes within the first 24 hours of injury such as procalcitonin, C-reactive protein, pH value, oxygenation index, base excess, and lactate; treatment such as whether conducted with mechanical ventilation, whether conducted with continuous renal replacement therapy, whether conducted with anticoagulation therapy, whether applied with vasoactive drugs, and fluid resuscitation. The analysis was conducted to screen the independent risk factors for the mortality within 28 days after injury in elderly patients with severe burns. Results:Among 124 patients, there were 82 males and 42 females, aged 60-97 years, with body mass index of 23.44 (21.09, 25.95) kg/m 2, total burn area of 54.00% (42.00%, 75.00%) total body surface area (TBSA), and full-thickness burn area of 25.00% (10.00%, 40.00%) TBSA. The patients were mainly combined with moderate to severe inhalation injury and caused by flame burns. There were 43 cases with underlying medical diseases. The majority of patients were admitted to the hospital within 8 hours after injury. There were statistically significant differences between patients in the 2 groups in terms of age, total burn area, full-thickness burn area, and inhalation injury, and PT, APTT, D-dimer, FDP, INR, white blood cell count, platelet count, urea, serum creatinine, blood glucose, blood sodium, uric acid, myoglobin, and urine volume within the first 24 hours of injury (with Z values of 2.37, 5.49, 5.26, 5.97, 2.18, 1.95, 2.68, 2.68, 2.51, 2.82, 2.14, 3.40, 5.31, 3.41, 2.35, 3.81, 2.16, and -3.82, respectively, P<0.05); there were statistically significant differences between two groups of patients in whether conducted with mechanical ventilation and whether applied with vasoactive drugs (with χ2 values of 9.44 and 28.50, respectively, P<0.05). Age, total burn area, full-thickness burn area, serum creatinine within the first 24 hours of injury, and APTT within the first 24 hours of injury were the independent risk factors for the mortality within 28 days after injury in elderly patients with severe burns (with odds ratios of 1.17, 1.10, 1.10, 1.09, and 1.27, 95% confidence intervals of 1.03-1.40, 1.04-1.21, 1.05-1.19, 1.05-1.17, and 1.07-1.69, respectively, P<0.05). Conclusions:The elderly patients with severe burns had the injuries mainly from flame burns, often accompanied by moderate to severe inhalation injury and enhanced inflammatory response, elevated blood glucose levels, activated fibrinolysis, and impaired organ function in the early stage, which are associated with their prognosis. Age, total burn area, full-thickness burn area, and serum creatinine and APTT within the first 24 hours of injury are the independent risk factors for death within 28 days after injury in this population.

Objective To explore the medication rules of Professor HUANG Li for the treatment of recurrent angina pectoris after percutaneous coronary intervention(PCI)for coronary heart disease by data mining method.Methods The prescriptions for effective cases of recurrent angina pectoris after PCI for coronary heart disease treated by Professor HUANG Li in the outpatient department of China-Japan Friendship Hospital were collected.SPSS Statistics 26.0 software and SPSS Modeler 18.0 software were used for frequency statistics,analysis of the therapeutic actions,properties,flavors and meridian tropism of the prescribed herbs as well as association rule analysis,cluster analysis and factor analysis of the herbs.Results A total of 344 Chinese medicine prescriptions were obtained,involving 209 herbs,with a cumulative frequency of 5 874 times.The top 30 Chinese medicinals were named as the high-frequency Chinese medicines,and the herbs with the frequency over 100 times in descending order were Astragali Radix,Chuanxiong Rhizoma,Puerariae Lobatae Radix,Rhodiolae Crenulatae Radix et Rhizoma,Notoginseng Radix et Rhizoma,Poria,Dalbergiae Odoriferae Lignum,Atractylodis Macrocephalae Rhizoma,Curcumae Rhizoma,Sparganii Rhizoma,Dioscoreae Rhizoma,Citri Reticulatae Pericarpium,Pinelliae Rhizoma Praeparatum,Codonopsis Radix,and Glycyrrhizae Radix et Rhizoma.The high-frequency Chinese medicinals were mostly classified as blood-activating and stasis-resolving drugs and qi-replenishing drugs.The medicinal properties of the drugs were characterized by being warm,mild,or cold,the flavors were predominated by being sweet,pungent or bitter,and the medicinals usually had the meridian tropism of the spleen,lung and liver meridians.A total of 30 association rules were mined out,cluster analysis yielded 5 herbal groups,and factor analysis yielded 11 groups of common factors.Conclusion For the treatment of cardiovascular diseases,Professor HUANG Li follows the theory of qi,blood and water,and especially pays more attention to the ascending and descending of qi movement.For qi deficiency and blood stasis contribute to the basic pathogenesis of recurrent angina pectoris after PCI,the therapy of benefiting qi,activating blood and removing stasis is recommended.Moreover,the simultaneous regulation of five zang-organs and simultaneous use of the cold and warm herbs are performed,and the herbs of benefiting qi and invigorating spleen,resolving phlegm and inducing diuresis,tranquilizing mind,promoting qi and dissipating masses,and activating blood to eliminate stasis are used for adjuvant therapy.
