ObjectiveTo investigate whether there are differences in the efficacy of Gegen Qinliantang with different contents of Puerariae Lobatae Radix on the acute enteritis （AE） model mice and provide a scientific basis for the interpretation of Gegen Qinliantang in the treatment of "Xie Re Li". MethodsA total of 112 male BALB/c mice were randomly divided into a blank group，model group，single Puerariae Lobatae Radix group，non-Puerariae Lobatae Radix group，regular dose Gegen Qinliantang group （regular dose group），half-dose Puerariae Lobatae Radix group，and doubled-dose Puerariae Lobatae Radix group， with 16 mice in each group. Hematoxylin-eosin （HE） staining was used to observe the pathological changes of the colon tissue. Western blot was employed to detect the expression of ZO-1 （a protein in the tight junction） and Occludin in the colon tissue， as well as the changes of tumor necrosis factor-α （TNF-α） and interleukin-1β （IL-1β）. ResultsCompared with the blank group，the DAI scores of the mice in the model group were significantly higher （P<0.05），and the histopathological sections of their colon tissues showed mucosal damage，glandular atrophy，disordered arrangement，and a large number of inflammatory cells infiltration，and the expression of ZO-1 and Occludin proteins in their colon tissues was significantly down-regulated （P<0.05，P<0.01）. The expression of inflammatory factors TNF-α and IL-1β was significantly up-regulated （P<0.05，P<0.01）. Compared with the model group，the DAI scores of mice in all dosing groups decreased significantly （P<0.05），with the most significant effect in the regular dose group. After 7 d of drug administration，the regular dose group had the best impact on the repair of colonic mucosa in the AE mouse model. The regular dose group significantly down-regulated the expression of TNF-α （P<0.05） and significantly up-regulated the expression of ZO-1 protein （P<0.05）. The doubled-dose Puerariae Lobatae Radix group significantly down-regulated the expression of IL-1β protein （P<0.01），and there was no significant difference between all dosing groups and the model group in terms of the expression of Occludin protein. After 14 d of drug administration，the best effect on the repair of colonic mucosa in the AE mouse model was observed in the doubled dose Puerariae Lobatae Radix group. All groups except the non-Puerariae Lobatae Radix group significantly down-regulated the expression of TNF-α （P<0.01）. Meanwhile，the regular dose group and doubled-dose Puerariae Lobatae Radix group significantly elevated the expression level of Occludin protein （P<0.01）. The doubled-dose Puerariae Lobatae Radix group also significantly inhibited the expression of IL-1β protein （P<0.05） and up-regulated ZO-1 protein expression （P<0.05）. ConclusionGegen Qinliantang can reduce the pathological damage of colon tissue， protect the barrier function and structure of intestinal epithelial cells， and reduce the expression of inflammatory factors， so as to achieve the therapeutic effect of AE model mice. When comparing the therapeutic efficacy of Gegen Qinliantang containing different Gegen contents， Gegen Qinliantang with the proportion of the original formula of Zhongjing was the most effective in AE model mice.

Objective:The purpose of this study was to explore the critical values of monitored indexes of perioperative major adverse cardiac events(MACE), so as to take effective prevention and treatment measures in time to maintain the stability of perioperative cardiac function to further improve the perioperative safety of elderly patients with biliary diseases.Methods:The clinical data of 246 elderly patients with biliary diseases in our hospital from May 2016 to February 2022 were collected.According to whether MACE occurred during the perioperative period, they were divided into the MACE group and the non-MACE group.The differences of clinical data, the monitoring indexes of postoperative cardiac function, and the coagulation function between the two groups were compared and analyzed.Logistic regression was used to analyze the independent risk factors of perioperative MACE, the cut-off value of the receiver operating characteristic(ROC)curve was calculated, and the Logistic multivariate prediction model was established.Results:In the MACE compared with the non-MACE group, age, postoperative complications and mortality, postoperative hospital stay, and the levels of postoperative high sensitivity troponin-I(Hs-TnI), creatine kinase isoenzyme(CK-MB), myoglobin(MYO), B-type natriuretic peptide(BNP), and D-dimer(D-D)were significantly increased(all P<0.05). Multivariate Logistic regression showed that postoperative BNP and D-D were two independent risk factors for perioperative MACE, and their cut-off values in the ROC curve were 382.65 pg/mL and 0.975mg/L respectively.The Logistic multivariate prediction model established by the Logistic regression equation was P= ex/(1+ ex), X=-5.710+ 0.003X 1+ 0.811X 2, where X 1 was the postoperative BNP level and X 2 was the postoperative D-D level.The accuracy, specificity and sensitivity of this prediction model for predicting perioperative MACE were 96.3%(237/246), 100.0%(235/235), and 18.2%(2/11). Conclusions:The Logistic multivariate prediction model established in this study can effectively predict the occurrence of perioperative MACE in elderly patients.Postoperative BNP and D-D were two independent risk factors for perioperative MACE.The cut-off values of BNP and D-D in the ROC curve could be used as critical values for monitoring perioperative MACE.Therefore, it is of great clinical significance to take effective prevention and treatment measures in time to maintain the stability of perioperative cardiac function, and further improve the perioperative safety of elderly patients with biliary diseases.

OBJECTIVE: To observe the efficacy and safety of Guihuang Formula (GHF) in treating patients with type III prostatitis and Chinese medicine syndrome of dampness-heat and blood stasis. METHODS: Sixty-six patients diagnosed with type III prostatitis with dampness-heat and blood stasis syndrome were randomly divided into the treatment group (GHF) and the control group (tamsulosin) using a random number table, with 33 cases each group. The treatment group received GHF twice a day, and the control group received tamsulosin 0.2 mg once daily before bedtime. Patients in both groups received treatment for 6 weeks and was followed up for 2 weeks. The outcomes included the National Institute of Health Chronic Prostatitis Symptom Index (NIH-CPSI) score, Chinese Medicine Symptoms Score (CMSS), expressed prostatic secretions (EPS) and adverse events (AEs). RESULTS: After treatment, the NIH-CPSI total score and domain scores of pain discomfort, urination and quality of life decreased significantly from the baseline in both groups (P<0.05). The CMSS score decreased in both groups (P<0.05). The WBC count decreased and lecithin body count increased in both groups (P<0.05). GHF showed a more obvious advantage in reducing the pain discomfort and quality of life domain scores of NIH-CPSI, reducing the CMSS score, increasing the improvement rate of the WBC and lecithin body counts, compared with the control group (P<0.05). There were no significant differences in decreasing urination domain score of NIH-CPSI between two groups (P>0.05). In addition, no serious AEs were observed. CONCLUSION GHF is effective in treating type III prostatitis patients with dampness-heat and blood stasis syndrome without serious AEs. (Registration No. ChiCTR1900026966).

Objective:To evaluate the value of cerebrospinal fluid (CSF) nerve injury-related proteins levels in predicting postoperative delirium (POD) in patients.Methods:A total of 1 000 patients of both sexes, aged 40-90 yr, of American Society of Anesthesiologists physical status Ⅰ or Ⅱ, with Mini-Mental State Examination score>24 at 1 day before operation, undergoing elective knee/hip arthroplasty under spinal-epidural anesthesia , were enrolled in this study.Cubital venous blood samples were drawn before anesthesia for detection of the concentrations of plasma total cholesterol, high-density lipoprotein, low-density lipoprotein and triglyceride.CSF 2ml was extracted after successful spinal-epidural anesthesia puncture for measurement of concentrations of α-synuclein (α-syn), β-amyloid protein 1-40 (Aβ 1-40), Aβ 1-42, total-Tau (t-Tau), phosphorylated Tau (p-Tau), progranulin (PGRN) and soluble myeloid cell triggering receptor 2 (sTREM2) (by enzyme-linked immunosorbent assay). The Confusion Assessment Method was used at 1, 3 and 7 days after surgery to evaluate the occurrence of POD.The patients were divided into POD group and non-POD group according to whether POD occurred after operation.Logistic regression analysis was used to analyze the variables of which P values were less than 0.05 to analyze the risk factors for POD.The receiver operating characteristic (ROC) curve was drawn and area (AUC) under the curve was calculated to evaluate the accuracy of the related risk factors in predicting POD. Results:A total of 964 patients were enrolled in the study, and 108 patients were diagnosed with POD, and the incidence was 11.2%.The results of logistic regression analysis found that age and and increased α-syn in CSF concentration were risk factors for POD, and decreased PGRN in CSF concentration and Aβ 1-42/p-Tau in CSF were the protective factors for POD ( P<0.05). ROC curve analysis showed that α-syn (AUC 0.69, 95% confidence interval (CI) 0.634-0.748, sensitivity 57.41%, specificity 82.10%, Youden Index 0.3951), PGRN in CSF concentration (AUC 0.695, 95%CI 0.637-0.750, sensitivity 59.26%, specificity 80.86%, Youden Index 0.4012) and Aβ 1-42/p-Tau in CSF (AUC 0.635, 95%CI 0.574-0.692, sensitivity 93.52%, specificity 30.25%, Youden Index 0.2377) could predict the occurrence of POD. Conclusion:PGRN, α-syn concentration and Aβ 1-42/p-Tau in CSF can predict the occurrence of POD in patients.

Objective:To investigate the relationship between preoperative subjective cognitive decline (SCD) and postoperative delirium (POD) in elderly patients.Methods:A total of 292 elderly patients of both sexes, aged 65-90 yr, weighing 50-90 kg, of American Society of Anesthesiologists physical status Ⅰ-Ⅱ, with Mini-Mental State Examination (MMSE) score>23 and Montreal Cognitive Assessment (MoCA) score > 26 at 1 day before operation, underwent total knee/hip arthroplasty under combined spinal-epidural block in our hospital from January to December 2020, were collected.The development of SCD was evaluated using subjective cognitive decline scale at 1 day before operation.Cerebrospinal fluid (CSF) was extracted after successful spinal-epidural anesthesia puncture, the concentrations of β-amyloid protein 40 (Aβ 40), Aβ 42, total tau (t-tau) and phosphorylated tau (p-tau) were determined by enzyme-linked immunosorbent assay.The incidence of POD was evaluated using confusion assessment method during post-anesthesia care unit and at 1-7 days after operation (or before discharge). Patients were divided into POD group and non-POD group according to whether POD occurred within 7 days after operation.The risk factors of which P values were less than 0.05 would enter the logistic regression analysis to stratify the risk factor for incidence of POD. Results:A total of 205 patients were enrolled and 53 patients developed POD (25.8%). The results of logistic regression analysis showed that preoperative SCD, and increased CSF p-tau and t-tau concentrations were risk factors for POD of elderly patients, and increased CSF Aβ 42 concentration and Aβ 40/p-tau, Aβ 40/t-tau, Aβ 42/p-tau and Aβ 42/t-tau were the protective factors for POD in elderly patients ( P<0.05). After correction of the confounding factors such as age, sex, body weight, education, the history of smoking and drinking, hypertension, diabetes and coronary heart disease, family history of dementia, Pittsburgh sleep quality index (PSQI), MMSE and MoCA score at 1 day before operation, duration of surgery, duration of anesthesia, intraoperative volume of infusion and blood loss and postoperative pain score, SCD, and increased CSF p-tau and t-tau concentrations were still the risk factors for POD in elderly patients, and increased CSF Aβ 42 concentration and Aβ 40/p-tau, Aβ 40/t-tau, Aβ 42/p-tau and Aβ 42/t-tau were still the protective factors for POD in elderly patients ( P<0.05). Conclusion:Preoperative SCD is the risk factor for POD in elderly patients.

Objective:To evaluate the relationship between preoperative cerebrospinal fluid/serum albumin ratio (Q-alb) and postoperative delirium (POD) in patients undergoing neuraxial anesthesia.Methods:The patients, aged 40-90 yr, of American Society of Anesthesiologists physical status Ⅰ or Ⅱ, underwent total knee/hip replacement under combined spinal-epidural block in our hospital from January 2018 to December 2020, were collected.After admission to the operating room, venous blood and cerebrospinal fluid samples were collected for determination of cerebrospinal fluid albumin, β-amyloid (Aβ) 1-42, Aβ 1-40, total tau protein (t-Tau), phosphorylated tau protein (p-Tau) and serum albumin levels (by enzyme-linked immunosorbent assay) and for calculation of Q-alb.When Q-alb was more than 10.2, the patient was considered to have blood-brain barrier disruption.Mini-Mental State Examination scale was used to evaluate the cognitive level on 1 day before surgery. The development of POD was evaluated using Confusion Assessment Method Chinese Reversion and Memorial Delirium Assessment Scale at 1-7 days after surgery.The patients were divided into POD group (P group) and non-POD (NP group) according to whether POD occurred.The receiver operating characteristic (ROC) curve was used to analyze the accuracy of Q-alb in predicting POD. Results:There were 49 cases in each group.Compared with group NP, concentrations of Aβ 1-42 and Aβ 1-40 were significantly decreased, concentrations of t-Tau and p-Tau albumin were increased, the ratio of Q-alb and blood-brain barrier disruption was increased in group P ( P<0.05). Before and after adjusting for confounding factors, Q-alb, cerebrospinal fluid Aβ 1-42, Aβ 1-40, t-Tau and p-Tau levels were risk factors for POD ( P<0.05). There was a positive linear regression relationship between Q-alb and levels of t-Tau and p-Tauin cerebrospinal fluid (t-Tau: β=0.587, P<0.001; p-Tau: β=0.427, P<0.001), and there was a negative linear regression relationship between Q-alb and levels of Aβ 1-42 and Aβ 1-40 in cerebrospinal fluid (Aβ 1-42: β=-0.762, P<0.001; Aβ 1-40: β=-0.531, P<0.001). There was no linear regression relationship between Q-alb and level of p-Tau in group P ( P=0.121). There was no linear regression relationship between Q-alb and level of Aβ 1-40 in group NP ( P=0.467). The results of ROC curve analysis showed that the area under the curve for Q-alb in predicting POD (95% confidence interval) was 0.827 (0.738-0.896). Conclusion:Preoperative higher Q-alb is the risk factor for POD in patients undergoing neuraxial anesthesia, and is more accurate in predicting POD.

Aim To investigate the protective effect of Huoxue Jiedu recipe on autophagy injury of H9C2 cardiomyocytes induced by hypoxia/reoxygenation and its mechanism. Methods H9C2 cardiomyocytes were used to establish a hypoxia/reoxygenation injury model. The effective concentration was screened and the cell activity was detected by CCK8 assay. The apoptotic rate of myocardial cells was detected by flow cytometry. The expression of autophagy marker LC3 was observed by laser confocal microscopy. The mRNA levels of Beclin-1, LC3 and Bcl-2 were detected by real-time quantitative PCR. The expressions of Beclin-1, LC311/I, Cleaved caspase-3, β-catenin, p-p65, Bcl-2, p62, p-Akt, p-mTOR were detected by Western blot. Results Huoxue Jiedu recipe can enhance the growth activity of myocardial cells and reduce the apoptotic rate and autophagy level, and it can enhance the activation of PI3K/Akt/mTORCl pathway, decrease Beclin-1 and LC3 mRNA levels, while increase Bcl-2 mRNA levels. It also decreased the expression of Beclin-1, LC311/I, Cleaved caspase-3, β-catenin, p-p65, and increased the expression of p62, p-Akt, p-mTOR, and Bcl-2. Conclusions Huoxue Jiedu recipe can reduce the level of autophagy and apoptosis of myocardial cells by regulating the autophagy pathway of PI3K/Akt/mTORCl, thereby playing a protective role in hypoxia/reoxygenation H9C2 myocardial cells.
