OBJECTIVE To assess the safety profile of sintilimab in combination with chemotherapy for the treatment of cholangiocarcinoma. METHODS The data of patients with cholangiocarcinoma from January 1st， 2021 to December 31st， 2022 were collected and divided into control group （29 cases） and observation group （18 cases） based on different medication regimens. Patients in the control group were treated with Gemcitabine hydrochloride for injection+Cisplatin for injection or Oxaliplatin for injection， the observation group was treated with Sintilimab injection based on the control group. Patients in each group underwent blood routine， liver and kidney function， biochemical and other examinations before and after each treatment cycle to observe the occurrence of adverse drug reactions. The correlation of adverse drug reactions with drugs was evaluated with Naranjo’s scale. RESULTS The correlation between blood toxicity and drug use was deemed “probable” in both groups； however， the observation group exhibited a significantly higher score， indicating a stronger correlation. In the control group， hepatotoxic reactions were classified as “suspicious” whereas in the observation group， they were categorized as “probable”. The correlation of gastrointestinal symptoms between the two groups was considered “possible”. Systemic symptoms， skin toxicity， musculoskeletal toxicity， endocrine toxicity and renal toxicity were all classified as having a “suspicious” correlation with drug use. The total incidence of blood toxicity in the observation group was significantly higher than control group （P＝0.014）. There was no statistically significant difference in the total incidences of hepatotoxic， gastrointestinal symptoms， systemic symptoms， skin toxicity， musculoskeletal toxicity， endocrine toxicity， renal toxicity， or the incidence of grade 3 or higher blood toxicity， hepatotoxic between the two groups （P＞0.05）. For the patients experiencing adverse drug reactions， the symptoms were alleviated following drug discontinuation or symptomatic supportive treatment. No fatalities occurred during the treatment period. CONCLUSIONS Sintilimab combined with chemotherapy may significantly increase the risk of blood toxicity in patients with cholangiocarcinoma， especially thrombocytopenia， but the adverse reactions are within a controllable range， and the overall safety is good.

ObjectiveTo analyze the adverse reactions associated with the clinical use of Banxia （Rhizoma Pinelliae）- Wutou （Aconitum） in the same formula， with the aim of providing a reference for the safety of their clinical application. MethodsLiterature on the clinical application of antagonistic herbs "Banxia-Wutou" used in the same formula， published from January 1st， 2014， to June 30th， 2023， was retrieved from databases including CNKI， VIP， Wanfang， SinoMed， PubMed， Cochrane Library， and Embase. A database was established， and information related to adverse reactions was extracted， including descriptions， classifications， specific manifestations， management and outcomes， patients' primary diseases （western medicine diseases and traditional Chinese medicine diagnoses and syndromes）， and medication information （dosage， ratio， administration routes， and dosage forms）. ResultsA total of 79 researches simultaneously used antagonistic herbs Banxia-Wutou in the same formula and reported associated advers reactions. Gastrointestinal adverse reactions were the most common， with 8 studies reporting management of adverse reactions and 3 studies reporting improvement with no intervention. Among the 11 researches， the adverse reaction relieved to extant， while other 69 researches didn't report the managment of adverse reaction and its prognosis. For the primary disease in western medicine system， chronic bronchitis and chronic obstructive pulmonary disease （COPD） were most common， while gastric pain was the most common symptom in traditional Chinese medicine with spleen and kidney deficiency and spleen stomach cold deficiency being the most frequent syndromes. The most common Banxia dosage was 10 g， while for the Wutou， Fuzi （Radix Aconiti Lateralis Praeparata） was predominant with the highest dose at 15 g. The most frequent herbal combination was Banxia-fuzi， with a 1∶1 ratio. The main administration route was oral， and the primary dosage form was decoction. ConclusionGastrointestinal adverse reactions are the most common in the clinical use of Banxia-Wutou antagonistic herb combinations. Research on the safety of "Banxia-Wutou" combinations should focus on respiratory system diseases and spleen-stomach related conditions.

Objective To investigate the expression and prognostic value of serum receptor for advanced glycation end products(RAGE)and CXC-chemokine ligand 16(CXCL16)in patients with sepsis complicated with acute respiratory distress syndrome(ARDS).Methods A total of 234 patients with sepsis diagnosed and treated in a hospital from January 2019 to January 2022 were selected as the study subjects,and were divided into 82 patients with sepsis complicated with ARDS(ARDS group)and 152 patients with sepsis without ARDS(non-ARDS group)according to whether the subjects were complicated with ARDS.ARDS group was divided into survival group(n=50)and death group(n=32)according to the survival status within 28 days of admission.Another 60 healthy subjects who underwent physical examination in the same period were se-lected as the control group.Serum RAGE and CXCL16 levels were detected by enzyme-linked immunosorbent assay.Pearson correlation analysis of serum RAGE and CXCL16 levels with sequential organ failure assess-ment(SOFA)score,acute physiology and chronic health evaluation Ⅱ(APACHE Ⅱ)score and oxygenation index in patients with sepsis and ARDS.Multivariate Logistic regression analysis of prognostic factors of sep-sis complicated with ARDS.The predictive value of serum RAGE and CXCL16 on the prognosis of sepsis complicated with ARDS patients was analyzed by receiver operating characteristic curve.Results The serum RAGE and CXCL16 levels in ARDS group were higher than those in non-ARDS group and control group,and the serum RAGE and CXCL16 levels in non-ARDS group were higher than those in control group,the differ-ence was statistically significant(P＜0.05).Compared with the survival group,the mechanical ventilation time,intensive care unit stay time,procalcitonin,SOFA score,APACHE Ⅱ score,serum RAGE,CXCL16 lev-els were higher in the death group,and the oxygenation index was lower,with statistical significance(all P＜0.05).The serum RAGE level in patients with sepsis complicated with ARDS was positively correlated with SOFA score and APACHE Ⅱ score(r=0.603,0.671,P＜0.05).Serum CXCL16 levels were positively corre-lated with SOFA score and APACHE Ⅱ score(r=0.655,0.707,P＜0.05).Serum RAGE and CXCL16 were negatively correlated with oxygenation index(r=-0.712,-0.683,P＜0.05).Multi-factor Logistics regres-sion analysis showed that serum RAGE and CXCL16 were independent risk factors for death within 28 days of admission in patients with sepsis complicated with ARDS.The area under the curve(AUC)of combined de-tection of serum RAGE and CXCL16 for predicting death within 28 days of admission in patients with sepsis complicated with ARDS was 0.882,which was higher than that of single index detection of serum RAGE and CXCL16,and the difference was statistically significant(Z=4.450,4.906,P＜0.05).Conclusion The com-bined detection of serum RAGE and CXCL16 is helpful to evaluate the clinical prognosis of sepsis complicated with ARDS patients.

Objective To analyze the quality of 22 batches of Fritillariae thunbergii bulbus Formula Granules from 12 different manufacturers by using water-extraction reference substance of Fritillariae thunbergii bulbus(ZBM ERS ST)and water-extraction reference substance of Fritillariae hupehensis bulbus(HBBM ERS ST)as references.Methods Ethyl acetate-methanol-triethylamine-water(17∶1∶1∶0.5)was used as the developing solvent for high-performance thin-layer chromatography(HPTLC)fingerprint analysis.The high-performance liquid chromatography(HPLC)fingerprint analysis was performed on a Agilent Eclipse XDB-C18 column(4.6 mm×250 mm,5 μm)with the gradient mobile phase consisted of acetonitrile-0.03%diethylamine solution.The column temperature was set at 25℃and evaporative light-scattering detector was used.The determination was conducted according to standard test method for measurement of Fritillariae thunbergii bulbus Formula Granules(Guangdong PFKL00117).Results The results of HPTLC and HPLC analysis showed that there are significant differences among the 22 batches of Fritillariae thunbergii bulbus Formula Granules.There were 4 batches of Fritillariae thunbergii bulbus Formula Granules from 3 manufacturers among them showed fingerprint characteristics of Fritillariae hupehensis bulbus.The total amount of peimine and peiminine in the remaining 18 batches of Fritillariae thunbergii bulbus Formula Granules was 0.291-3.179 mg·g-1,which were quite different.Conclusion Currently,the quality of Fritillariae thunbergii bulbus Formula Granules on the market varies greatly.Standardized water-extract reference substance has better applicability for the analysis of the quality of Fritillariae thunbergii bulbus Formula Granules than the control medicinal materials.

Liver fibrosis is a repair response to chronic liver injury caused by various etiologies. Its continuous progression can develop into liver cirrhosis or even hepatocellular carcinoma, eventually leading to liver failure. Currently, there is no effective treatment for liver fibrosis. Hepatic macrophages play a key role in intrahepatic inflammatory response, progression and resolution of fibrosis, and have emerged as an important therapeutic target for anti-hepatic fibrosis. The function of hepatic macrophages in the process of liver fibrosis was mainly reviewed and the mode of action of hepatic macrophages from various aspects was discussed to provide ideas for the treatment of liver fibrosis.

ObjectiveTo observe the effects of Sargassum and Glycyrrhizae Radix et Rhizoma incompatible pair with the Haizao Yuhutang （HYT） on oxidative stress in the liver of goiter rats under the condition of 2 times the dose limit of the Pharmacopoeia of the People's Republic of China 2020. MethodA total of 128 male Wistar rats were randomly divided into a blank group， a model group， a euthyrox group （20 μg·kg^-1）， a HYT group （12.06 g·kg^-1）， a HYT without Sargassum （HYT-H） group （9.90 g·kg^-1）， a HYT without Glycyrrhizae Radix et Rhizoma （HYT-G） group （10.26 g·kg^-1）， a HYT without Sargassum and Glycyrrhizae Radix et Rhizoma （HYT-HG） group （8.10 g·kg^-1）， and a Sargassum and Glycyrrhizae Radix et Rhizoma （HG） group （3.96 g·kg^-1）. The blank group was given deionized water by gavage， and the others were given propylthiouracil （PTU） to replicate the goiter pathological model. Euthyrox was taken as a positive control drug， and the rest of the Chinese medicine groups were given the corresponding decoction by gavage， the material was collected 12 hours after the last dose. The serum levels of aspartate aminotransferase （AST）， alanine aminotransferase （ALT）， alkaline phosphatase （ALP）， and the contents of superoxide dismutase （SOD）， glutathione peroxidase （GSH-Px）， malondialdehyde （MDA）， reactive oxygen species （ROS） in liver tissue were detected in each group. The pathological changes in the liver were observed via hematoxylin-eosin （HE） staining. Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） was utilized to detect the mRNA expressions of Kelch-like Ech-associated protein 1 （Keap1）， nuclear factor E₂-related factor 2 （Nrf2）， heme oxygenase-1 （HO-1）， p53 and Caspase-3 in liver tissues. Western blot was adopted to detect the protein expressions of Nrf2 and HO-1 in liver tissues in oxidative stress-related signaling pathways. ResultCompared with control group， the model group showed significantly increased serum ALT level and contents of MDA and ROS in liver tissues （P<0.05， P<0.01）， significantly reduced activities of SOD and GSH-Px in the liver （P<0.01）， significantly increased mRNA expression of Keap1 （P<0.01）， and significantly decreased mRNA and protein expressions of Nrf2 and HO-1 （P<0.05， P<0.01）. Compared with the model group， the HYT group manifested significantly reduced serum levels of AST， ALT， and ALP （P<0.05， P<0.01）， significantly reduced contents of MDA and ROS in liver tissue （P<0.01）， significantly increased the activities of SOD and GSH-Px （P<0.01）， significantly decreased mRNA expressions of Keap1， p53， and Caspase-3 （P<0.01）， and significantly increased mRNA and protein expressions of Nrf2 and HO-1 （P<0.05， P<0.01）. ConclusionUnder the condition of 2 times the dose limit of the Pharmacopoeia of the People's Republic of China 2020， Sargassum and Glycyrrhizae Radix et Rhizoma incompatible pair with the HYT on oxidative stress in the liver of goiter rats had different effects. The HYT that contains Sargassum and Glycyrrhizae Radix et Rhizoma has a protective effect on the liver of goiter rats， and the effect is better than that of the HG group， the euthyrox group， and the incomplete groups. Its mechanism may be related to activating the Nrf2/HO-1 signaling pathway to alleviate liver oxidative stress and inhibiting the p53/Caspase-3 signaling pathway to reduce hepatocyte apoptosis.

Objective To explore the effects of multiple groups of acupoint pre-embedding thread on the autonomic nervous system and gastrointestinal function in patients undergoing gynecological laparo-scopic surgery under general anesthesia.Methods Sixty patients,aged 25-64 years,BMI 18.5-30.0 kg/m2,ASA physical status Ⅰ or Ⅱ,were selected for laparoscopic gynecological surgery under general anesthesia.Patients were divided into two groups using a random number table method:control group(group C)and acupoint thread embedding group(group M),30 patients in each group.Patients in group M received thread embedding at 10 acupoints in 5 groups,including Neiguan,Sanyinjiao,Geshu,Jueyin,and Weishu on the day before surgery.Patients in group C did not undergo thread embedding at acupoints before surgery.The HR,MAP,normalized unit of low frequency(LF),normalized unit of high frequency(HF)and LF/HF were recorded at 5 minutes before anesthesia induction,immediately after tracheal intu-bation,immediately after establishing pneumoperitoneum,10,20,and 30 minutes after pneumoperitoneum,and when tracheal intubation was removed.Motilin and gastrin concentrations in serum were measured on the day before surgery and 24 hours after surgery.The time of first postoperative exhaust and defecation,as well as the occurrence of nausea and vomiting within 48 hours after surgery were recorded.Results Compared with group C,the HR was significantly lower,and the MAP,the LF and LF/HF in group M were significant-ly reduced at 10,20,and 30 minutes after pneumoperitoneum,while HF was significantly increased(P＜0.05).The first postoperative time of exhaust and defecation in group M was significantly shortened(P＜0.05),and the incidence of nausea and vomiting within 24 hours after surgery was significantly reduced(P＜0.05).The concentrations of motilin and gastrin in serum of group M were significantly increased 24 hours after surgery(P＜0.05).Conclusion The combination of acupoints and pre-embedding thread can regu-late the autonomic nervous function of patients undergoing gynecological laparoscopic surgery under general anesthesia,which is beneficial for the recovery of postoperative gastrointestinal function and improves the quality of rehabilitation.

Rheumatoid arthritis(RA)is an autoimmune disease characterized by chronic synovial in-flammation.Moxibustion treatment can significantly improve RA immune disorders and reduce synovial in-flammation,but its mechanism of action needs to be further deepened.Senescence is a key factor that induces the occurrence and development of RA,and macrophages,as the key sentinel sites of the immune system to monitor aging,play an important role in the onset process of RA.The circadian clock dominates the circadian rhythm of the body,regulates the expression of a variety of proteins and cell functions,and is widely involved in the physiological and pathological processes of a variety of diseases.The circadian clock is involved in mac-rophage senescence and has the effect of regulating immune disorders.Among the mechanisms affecting the occurrence and development of RA,macrophage senescence has received more and more attentions as an im-portant breakthrough point.Therefore,this article mainly elucidates the possible pathogenesis of RA from the perspective of the involvement of the biological clock in macrophage senescence and analyzes the feasibility of moxi-bustion in the treatment of RA by regulating the biological clock and participating in macrophage senescence.

Objective To determine the effects of treadmill training on the structure of hippocampal myelin and cognitive function in rats exposed to acute plateau hypoxia.Methods With 30 SPF-grade female SD rats (aged 6-8 weeks,weighing 200-220 g),6 of them were used for observation of myelin structure after injury,and the remaining 24 rats were randomly divided into control group,hypobaric hypoxia group and treadmill training group (n=8).The rats in above experimental groups were placed in a low-pressure oxygen chamber at an altitude of 6000 m for 7 consecutive days,and the rats of the control group were placed in the confined chamber for the same period without hypoxia.Then,the rats of the treadmill training group received a 4-week treadmill training scheme since the day after hypoxia.Finally,all the rats were tested for cognitive function with open field test (OFT)and Morris water maze (MWM).Transmission electron microscopy (TEM) was used to observe the changes of demyelination in the hippocampus. The expression of oligodendrocyte transcription factor 2 (Olig2)and myelin basic protein (MBP )in the hippocampal CA1 and CA3 regions was measured by immunofluorescence staining and Western blotting.Results Behavioral tests showed that the number into the central area,total distance,distance ratio in OFT and the number of platform crossings and distance to the target area in MWM were reduced in the hypobaric hypoxia group than the control group (P<0.05 ),while these indexes were increased in the treadmill training group than in the hypobaric hypoxia group (P<0.05).Immunofluorescence staining indicated that the number of Olig2 positive cells per unit area and the mean fluorescence intensity of MBP in the CA1 and CA3 regions were significantly lessen in the hypobaric hypoxia group than the control group (P<0.05 ),while these indicators were higher in the treadmill training group than the hypobaric hypoxia group (P<0.05 ).Western blotting displayed that the expression levels of Olig2 and MBP in the hippocampus were obviously lower in the hypobaric hypoxia group than the control group (P<0.01 ),while the levels were increased in the treadmill training group than the hypobaric hypoxia group (P<0.01 ).Conclusion Treadmill training promotes the number of the oligodendrocyte spectrum cells in CA1 and CA3 regions,enhances the expression of myelin-related proteins and improves myelin repair in hippocampus of hypobaric hypoxia rats,and thereby ameliorates hypoxia-induced anxiety-like behaviors and memory dysfunction.
