OBJECTIVE To investigate the effects and mechanisms of oliceridine fumarate （TRV130） in improving postoperative cognitive dysfunction （POCD） in elderly rats based on the Toll-like receptor 4 （TLR4）/nuclear factor-κB （NF-κB） pathway. METHODS Rats were randomly divided into the control group （normal saline）， the model group （normal saline）， the TRV130 group （2.8 mg/kg）， the TLR4/NF-κB pathway inhibitor （TAK-242） group （3 mg/kg）， the β -arrestin inhibitor （Barbadin） group （3 mg/kg）， and the traditional opioid drug （morphine） group （2.8 mg/kg）， with 15 rats in each group. Except for the control group， POCD models were established in all other groups. From the first day after surgery， drugs/normal saline were administered via caudal vein injection once daily for 3 consecutive days. After the last administration， the pathological damage of hippocampal tissue was observed； the cognitive function， serum inflammatory factor levels， hippocampal neurons apoptosis rate， and the expression of ionized calcium-binding adapter molecule 1 （Iba-1）， glial fibrillary acidic protein （GFAP）， and TLR4/NF-κB pathway-related mRNA and protein in hippocampal tissue were detected. RESULTS In the model group， the neurons in the CA1 region of the hippocampus were disordered and sparse， with decreased number， pyknotic and fragmented nuclei accompanied by inflammatory cell infiltration. Compared with the control group， the escape latency， serum levels of tumor necrosis factor α （TNF-α）， interleukin-6 （IL-6）， and IL-1β， hippocampal neurons apoptosis rate， average fluorescence intensities of Iba-1 and GFAP， mRNA expression levels of TLR4 and NF-κB p65， and their protein expression/phosphorylation levels in hippocampal tissue were significantly increased/elevated in the model group （ P ＜0.05）； the time spent in the target quadrant and the number of platform crossings were significantly shortened/decreased （ P ＜0.05）. Compared with the model group， the cognitive function， pathological， inflammatory， and apoptosis-related indicators were significantly improved in the TRV130 group， TAK-242 group， and Barbadin group （ P ＜0.05）； the mRNA expression levels of TLR4 and NF-κB p65 and their protein expression/phosphorylation levels were significantly decreased in the TRV130 group and TAK-242 group （ P ＜0.05）. CONCLUSIONS TRV130 may improve POCD in elderly rats by inhibiting the TLR4/NF-κB pathway and alleviating postoperative central nervous system inflammatory responses.

Objective:To observe and analyze the adverse drug reactions (ADRs) caused by adalimumab in patients with inflammatory bowel disease (IBD) and its influencing factors.Methods:A retrospective study was conducted on 106 patients with inflammatory bowel disease treated with adalimumab at Tianjin Medical University General Hospital from November 2019 to November 2023. Among them, 31 patients who experienced adverse reactions were included in the ADR group (case group), while 75 patients who did not experience adverse reactions were included in the non-ADR group (control group). Patients' basic information, laboratory tests, adverse drug reactions, etc were collected. Measurement data with normal distribution were expressed as xˉ± s and means between two groups were compared using independent samples t-test. The percentage of count data was calculated, and the rate between groups was compared by χ2 test. The risk factors of adverse drug reactions caused by adalimumab in patients with inflammatory bowel disease were analyzed by single factor screening and multivariable Logistic regression model. Results:ADR occurred in 31 of 106 patients, accounting for 29.25% (31/106), among those patients which infection was the most common,accounting for 18.87%(20/106). The number of combined drugs (≥3 kinds), drug allergy history, drug duration (≥3 months), blood concentration (>12 μg/mL) in ADR group were higher than those in non-ADR group ( χ2-values were 5.90, 5.78, 6.94 and 10.07, respectively,t-values were 8.55 and 0.97 respectively; all P<0.05). Multivariate Logistic regression results showed that the number of combined drugs ≥3, drug allergy history, drug duration >3 months, blood concentration >12 ng/L, creatinine and total bilirubin levels were all risk factors for adverse drug reactions of adalimumab in IBD patients (O R values were 2.680, 2.394, 3.228, 4.415, 3.673 and 4.646, respectively;95% CI:1.563~3.798, 1.434-3.354, 2.070-4.387, 3.803-5.027, 2.364-4.982 and 3.449-5.843, respectively; all P<0.05). Conclusion:The number of combined drugs ≥3, drug allergy history, drug duration >3 months, blood concentration >12 ng/L, creatinine and total bilirubin levels are all risk factors for adverse drug reactions in IBD patients with adalimumab. In clinical practice, it is necessary to strengthen monitoring and take timely preventive measures for IBD patients with the above-mentioned factors, in order to reduce the incidence of ADR.

Objective:To analyze the occurrence and influencing factors of adverse reactions in patients with inflammatory bowel disease (IBD) during the long-term treatment with vedolizumab (VDZ).Methods:The study was a retrospective observational design. The study subjects were selected from patients who long-termly used VDZ to treat moderate-to-severe active IBD in Tianjin Medical University General Hospital from February 1, 2021 to December 31, 2023. Clinical data of patients were collected through the hospital system of clinical pharmacy management, including general information, IBD condition, VDZ maintenance treatment plan, combination of drugs, laboratory test results, etc. The adverse reactions of VDZ were screened and their clinical manifestations, severity, intervention and outcomes were analyzed descriptively. The patients were divided into 2 groups according to whether VDZ adverse reactions occurred, and the differences in clinical data between them were compared; the influencing factors of adverse reactions were analyzed by multivariate logistic regression method.Results:A total of 142 patients were included in the study, including 81 males and 61 females, aged (37.6±6.4) years with a range from 18 to 57 years. There were 103 patients (72.5%) developed VDZ adverse reactions, which mainly involved skin (52 patients, account for 50.5%), digestive system (33 patients, account for 32.0%) and respiratory system (18 patients, account for 17.5%). All 103 patients did not stop VDZ treatment, and the adverse reaction symptoms disappeared or were relieved after symptomatic treatments. Compared with patients without VDZ adverse reactions, the age of patients with VDZ adverse reactions were higher [(39.5±5.4) years vs. (32.4±6.7) years], and the proportions of patients with chronic relapsing clinical type [65.0%(67/103) vs. 41.0%(16/39)], severe disease activity [60.2%(62/103) vs. 33.3%(13/39)], combined drug use [67.0%(69/103) vs. 46.2%(18/39)], and injecting VDZ once every 4 weeks during maintenance treatment [27.2%(28/103) vs. 10.3%(4/39)] in the group were larger, with statistical significance (all P<0.05). Multivariate logistic regression analysis showed that the chronic relapsing clinical type [odds ratio ( OR)=1.012, 95% confidence interval ( CI): 1.001-1.028, P=0.002], severe disease activity ( OR=1.096, 95% CI: 1.010-1.158, P=0.040), combination drugs ( OR=1.035, 95% CI: 1.003-1.122, P=0.041), VDZ maintenance therapy injection interval of 4 weeks ( OR=1.014, 95% CI: 1.002-1.113, P=0.005) were the risk factors for VDZ adverse reactions. Conclusions:Among IBD patients receiving long-term treatment of VDZ, the incidence of adverse reactions of VDZ was 72.5%, mainly involving skin, digestive system and respiratory system. Symptomatic treatments could be given, and the prognosis was good. Patients with chronic relapsing clinical type, severe disease activity, combination therapy, and shorter VDZ maintenance injection interval were at higher risk of adverse reactions.

OBJECTIVE To investigate the effects of formononetin （FMN） on the apoptosis of intestinal epithelial cells in inflammatory bowel disease （IBD） rats and its possible mechanism. METHODS IBD rat model was constructed by using trinitrobenzene sulfonic acid （TNBS） induction. Forty-eight rats with successful modeling were divided into model group （normal saline）， low-dose and high-dose FMN groups （20 and 40 mg/kg FMN）， and high-dose FMN+YAP inhibitor Verteporfin （VTPF） group （40 mg/kg FMN+10 mg/kg VTPF）， with 12 rats in each group. Another 12 rats were set as the normal group （normal saline）. They were given drug/normal saline， once a day， for 7 consecutive days. After the last administration， the disease activity index （DAI） of rats was calculated， and the colon length of rats in each group was measured. The pathological changes in the colon tissue of rats were observed. The levels of tumor necrosis factor-α （TNF-α）， interleukin-6 （IL-6） and IL-10 in serum were detected， and the apoptosis of intestinal epithelial cells was detected. The expressions of Yes associated protein （YAP）， cleaved cysteine-containing aspartate proteolytic enzyme 3 （cleaved-caspase-3）， B-cell lymphoma-2 （Bcl-2） and Bcl-2 associated X protein （Bax） were detected in colon tissue of rats. RESULTS Compared with the normal group， DAI score， the levels of TNF-α and IL- 6， the apoptotic rate of intestinal epithelial cells， and the expressions of cleaved-caspase-3 and Bax protein in the model group were increased greatly （P＜0.05）； the length of the colon was greatly decreased （P＜0.05）， and the serum level of IL-10 and the protein expressions of YAP and Bcl-2 were greatly reduced （P＜0.05）. The cell morphology of colon tissue was abnormal， with disordered arrangement and inflammatory cell infiltration. Compared with IBD group， the above indexes of rats were improved significantly in low-dose and high-dose FMN groups （P＜0.05）， in dose-dependent manner （P＜0.05）. VTPF significantly alleviated the effects of FMN on the above indexes of IBD rats （P＜0.05）. CONCLUSIONS FMN may promote the expression of YAP by inhibiting the Hippo/YAP signaling pathway， thereby inhibiting apoptosis of intestinal epithelial cells in IBD rats.

OBJECTIVE To establish an evaluation syste m of clinical effec tiveness of Drug Selection Guideline for Medical Institutions，and to provide reference for drug selection in medical institution. METHODS Retrieved from relevant Chinese government websites ，PubMed，Embase，CBM and CNKI ，etc.，from the inception to Sept. 14th 2021，related contents of clinical effectiveness related to three secondary indicators ，such as “recommended level and strength of guideline ”“clinical pathway ”and “evidence and level of efficacy ”were extracted respectively ；evaluation system was construction for the clinical effectiveness. RESULTS A total of 5，4 and 17 policy documents or literatures were included according to “recommended level and strength of guideline”“clinical pathway ”and“evidence and level of efficacy ”，respectively.“The recommended level and strength of drug guideline”could reflect the clinical effectiveness of drugs ，and the evaluation content referred to the recommended level and strength of the selected drugs in the guidelines for corresponding indications. “Clinical pathway ”was the embodiment of drug effectiveness, and the evaluation content referred to the clinical path of whether the selected drugs were included in the corresponding indications. The evaluation contents of “evidence and level of efficacy ”were different between chemical medicine/ biological agent and Chinese patent medicine ；evidence and quality level of efficacy research for chemical medicine/biological agent referred to GRADE system ，while those for Chinese patent medicine referred to classic works or clinical experience inheritance. Therefore，the evaluation contents of this index system were the evidence and quality level of the efficacy research related to selected drugs. CONCLUSIONS The evaluation system of clinical effectiveness of drugs constructed from the perspective of drug selection in medical institutions can lay the foundation of evaluation system for the construction of Drug Selection Guideline for Medical Institutions ，and also provide reference for drug selection in medical institutions.

Objective:To observe the effect of clinical pharmacists on the pain education in the patients with fracture. Methods:A total of 122 fracture patients with ASAⅠ/Ⅱaged 18-80 years were randomly divided into the intervention group (n=61) and the control group(n=61). The control group received the conventional orthopedic treatment..Flurbiprofen was injected for the postopera-tive analgesia,and if the pain VAS score was above 6,pethidine solution was given at the dose of 50 mg immediately. Based on the conventional treatment,the patients in the intervention group were educated by clinical pharmacist one day before the surgery,and then strengthened education was given after the surgery.The pain VAS score,and sleeping quality at 6h,24h,48h and 72h and satisfaction of pain management were compared between the groups.Results:The VAS score of the intervention group was significantly lower than that of the control group at 6 h,24 h,48 h and 72 h after the operation (P<0.05). The scores of sleeping quality in the intervention group at 6 h and 24 h after the operation were higher than those in the control group (P<0.05). The scores of patients' satisfaction were significantly higher in the intervention group than those of the control group (P<0.05). Conclusion: The clinical pharmacist's pain education can improve the degree of pain control and sleeping quality,increase the patients' satisfaction with pain control to a cer-tain extent.

Objective To investigate influence factors on neonatal necrotizing enterocolitis (NEC) and find a preventive way against the said disorder. Methods A retrospective study was conducted of 63 cases NEC (observation group) and 70 cases non-NEC (control group) admitted to the neonatal intensive care units (NICU) of two hospitals from January 2010 to May 2014. The cases were grouped in 29 factors. The individual factors of 28 out of the 29 factors were analy-sised with SAS 9.1 statistical software, and the screened important factors were investigated by logistic regression. Re-sults The ratios of 4 factors, application of prenatal corticosteroids, breast feeding prior to the ailment, oral probiotics and hyperbilirubinemia in the observation group were lower than those in the control group, while the ratios of 14 factors were higher than those in the control group, premature rupture of membrane, asphyxia, respiratory distress syndrome, respiratory failure, umbilical venous catheters, oxygen uptake, sepsis, septic shock, disseminated intravascular coagula-tion (DIC), congenital heart disease, scleredema, hyponatremia, hypocalcaemia and transfusion. The differences of fac-tors mentioned were of statistic significance (P<0.05), while the differences of other factors were not statistically signifi-cant between the two groups (P>0.05). Logistic regression analysis indicated that breast feeding, oral probiotics and hy-perbilirubinemia were protective factors against NEC; while sepsis, congenital heart disease and transfusion were major factors that lead to NEC. Conclusion NEC resulted from a combination of multiple factors, with sepsis, congenital heart disease and transfusion as the leading ones. Breast feeding, oral probiotics, and non-excessive curing against hyper-bilirubinemia will help reduce the incidence of NEC.
