ObjectiveTo predict the mechanism through which Shasheng Maidong Tang enhances the efficacy of chemotherapy for lung cancer via network pharmacology and validate the prediction results in animal experiments. MethodsThe potential mechanism through which Shasheng Maidong Tang enhances the efficacy of chemotherapy for lung cancer was predicted by network pharmacology， liquid chromatography-mass spectrometry （LC-MS）， and molecular docking methods. C57/BL6 mice were assigned into normal， model， cisplatin， and Shasheng Maidong Tang+cisplatin groups. In addition to the normal group， the remaining groups were injected subcutaneously with 0.2 mL of 1×10⁷ cells·mL^-1 Lewis lung cancer cells to establish the Lewis lung cancer model. The daily gavage dose of Shasheng Maidong Tang was 3.58 g·kg^-1， and the concentration of cisplatin intraperitoneally injected on every other day was 2 mg·kg^-1. Drugs were administered for 14 d. The changes in the tumor volume and the rate of tumor suppression were monitored， and the tumor histopathological changes were observed by hematoxylin-eosin （HE） staining. Enzyme-linked immunosorbent assay was employed to measure the interleukin （IL）-6 and interferon （IFN）-γ levels in peripheral blood. Real-time PCR was performed to quantify the mRNA levels of Janus kinase 2 （JAK2）， signal transducer and activator of transcription 1 （STAT1）， and signal transducer and activator of transcription 3 （STAT3） in the tumor tissue of mice. Western blot was employed to determine the protein levels of JAK2， STAT3， B-cell lymphoma-2 （Bcl-2）， cysteinyl aspartate-specific proteinase-3 （Caspase-3）， and Pim-1 proto1 （PIM1） in the tumor tissue. Immunohistochemistry was employed to detect the expression of Bcl-2 and PIM1 in the tumor tissue. ResultsNetwork pharmacological predictions indicated that Shasheng Maidong Tang might enhance the efficacy of chemotherapy for lung cancer by regulating nitrogen metabolism， AGE-RAGE signaling pathway， cancer pathway， and JAK/STAT signaling pathway. The experimental results demonstrated that tumor volume in the cisplatin group and Shasheng Maidong Tang+cisplatin group was reduced compared with the model group， with statistically distinct differences observed on days 14， 17， 20 post modeling （P<0.05）. Notably， the Shasheng Maidong Tang+cisplatin therapy further decreased tumor volume compared with the cisplatin group， showing marked reductions on days 17 and 20 （P<0.05）， consistent with trends visualized in tumor volume comparison charts. The Shasheng Maidong Tang+cisplatin group exhibited higher tumor inhibition rate than the cisplatin group （P<0.05）. Histopathological analysis via HE staining revealed that the tumors in the model group displayed frequent nuclear mitosis， densely arranged cells， hyperchromatic nuclei， and no necrosis. Cisplatin treatment induced partial necrosis and vacuolization， while the Shasheng Maidong Tang+cisplatin group exhibited extensive necrotic regions， maximal vacuolization， disarranged tumor cells， and minimal mitotic activity. Compared with the model group， the cisplatin group and the Shasheng Maidong Tang+cisplatin group showed elevated level of IFN-γ （P<0.01） and declined level of IL-6 （P<0.01） in the peripheral blood. Compared with the cisplatin group， the Shasheng Maidong Tang+cisplatin group presented elevated level of IFN-γ （P<0.01） and lowered level of IL-6 （P<0.01） in the peripheral blood. Compared with the model group， the cisplatin group and the Shasheng Maidong Tang+cisplatin groups showed down-regulated mRNA levels of JAK2 and STAT3 （P<0.01） and up-regulated mRNA level STAT1 （P<0.01）. Compared with the cisplatin group， the Shasheng Maidong Tang+cisplatin group presented down-regulated mRNA levels of JAK2 and STAT3 （P<0.01） and up-regulated mRNA level of STAT1 （P<0.01）. Compared with the model group， the cisplatin group and the Shasheng Maidong Tang+cisplatin group showed down-regulated protein levels of JAK2 （P<0.01）， Bcl-2 （P<0.01）， PIM1 （P<0.01）， and STAT3 （P<0.05）， and up-regulated protein level of Caspase-3 （P<0.01）. Compared with the cisplatin group， Shasheng Maidong Tang+cisplatin group presented down-regulated protein levels of JAK2 （P<0.01）， Bcl-2 （P<0.01）， PIM1 （P<0.01）， STAT3 （P<0.05）， and up-regulated protein level of Caspase-3 （P<0.01）. The Bcl-2 and PIM1 expression results obtained by immunohistochemistry were consistent with those of Western blot. ConclusionShasheng Maidong Tang may enhance the efficacy of chemotherapy in the mouse model of Lewis lung cancer by regulating the JAK2/STAT3 signaling pathway.

Osteoporosis is a common bone metabolic disease， which is mainly characterized by the decrease in the number of bone trabeculae and the destruction of bone tissue microstructure， leading to increased bone fragility and fracture risks. This disease is common in postmenopausal women， elderly men， diabetes patients， and obese people. Due to the lack of awareness to prevent bone losses and the limitations of bone mass measurement methods， osteoporosis is only concerned when there are serious complications， which imposes a heavy burden on both patients and medical resources. Oxidative stress refers to the excessive production of highly active molecules such as reactive oxygen species and reactive nitrogen in the body subjected to harmful stimuli， leading to the imbalance between the oxidative and antioxidant systems and causing oxidative damage. Studies have shown that oxidative stress can increase the generation and activity of osteoclasts and inhibit the differentiation of osteoblasts， thus playing a role in the occurrence and development of osteoporosis. Traditional Chinese medicine （TCM） is considered an effective antioxidant that can alleviate oxidative stress-induced osteoporosis by regulating a variety of signaling pathways. Studies have shown that TCM can alleviate oxidative stress and promote bone angiogenesis and osteogenesis by regulating the phosphatidylinositol 3-kinase （PI3K）/protein kinase B （Akt）， nuclear factor-kappa B， and nuclear factor erythroid 2-related factor （Nrf2） signaling pathways. TCM alleviates oxidative stress and promotes osteogenesis by regulating the Nrf2， PI3K/Akt/mammalian target of rapamycin， and secreted glycoprotein Wnt/β-catenin signaling pathways. In addition， TCM regulates NF-κB， mitogen-activated protein kinase， and receptor activator of nuclear factor kappa B （RANK）/RANK ligand/osteoprotegerin signaling pathway to alleviate excessive bone resorption induced by oxidative stress. This paper systematically summarizes the literature on the prevention and treatment of osteoporosis by TCM or its active ingredients via the above-mentioned signaling pathways to reduce oxidative stress in recent years. It briefs the possible molecular mechanisms of oxidative stress regulation-related signaling pathways to cause osteoporosis. In addition， this paper discusses the effects and mechanisms of TCM on bone angiogenesis， osteogenesis， and bone resorption by reducing oxidative stress through the regulation of related signaling pathways， aiming to provide a theoretical basis for the research and clinical treatment of osteoporosis.

OBJECTIVE: To explore the neuroprotective effect and underlying mechanism of Xingnao Kaiqiao acupuncture (acupuncture for regaining consciousness and opening orifices) in the rat models of cerebral ischemia-reperfusion injury (CIRI) based on the p53 protein (p53)/solute carrier family 7 member 11 (SLC7A11)/glutathione peroxidase 4 (GPX4) signaling pathway. METHODS: Of 102 male Wistar rats, 20 rats were randomly collected as a sham-operation group. Using a modified external carotid artery filament insertion method, CIRI models were prepared by occluding the middle cerebral artery in the rest rats. After modeling and excluding 1 non-successfully modeled rat and 1 dead one, the other modeled rats were randomized into a model group, an agonist group, an acupuncture group, and an acupuncture + agonist group, 20 rats in each one. Xingnao Kaiqiao acupuncture therapy was delivered in the rats of the acupuncture group and the acupuncture + agonist group. The acupoints included "Shuigou" (GV26), bilateral "Neiguan" (PC6), and "Sanyinjiao" (SP6) on the affected side. Electroacupuncture was attached to "Neiguan" (PC6) and "Sanyinjiao" (SP6) on the affected side, with dense-disperse wave, a frequency of 2 Hz/15 Hz and intensity of 1 mA. The intervention was delivered twice daily, 20 min each time and for 7 consecutive days. In the agonist group and acupuncture+agonist group, p53 agonist, COTI-2 was intraperitoneally injected (15 mg/kg), once daily for 7 consecutive days. Neurological deficit was evaluated using Zausinger's six-point scale. Cerebral infarction volume was quantified by triphenyl tetrazolium chloride (TTC) staining. Histopathological changes were observed using hematoxylin-eosin (HE) staining. Iron deposition was assessed by Prussian blue staining. Mitochondrial ultrastructure in the ischemic cortex was examined under transmission electron microscopy (TEM). Serum iron (Fe²⁺) was measured with chromometry. Malondialdehyde (MDA) and glutathione (GSH) levels in the ischemic hippocampus were determined using thiobarbituric acid and microplate assays, respectively. The mean fluorescence intensity of reactive oxygen species (ROS) in the ischemic cortex was analyzed by flow cytometry. The mRNA and protein expression of GPX4, SLC7A11, and p53 in the ischemic hippocampus were evaluated using quantitative real-time PCR (qRT-PCR) and Western blotting, respectively. RESULTS: Compared with the sham-operated group, the model group exhibited the decrease in neurological deficit score (P<0.01), and the increase in cerebral infarction volume percentage (P<0.01). The changes of brain tissue were presented in extensive cellular necrosis, pyknotic and deeply-stained nuclei, and vacuolar degeneration. The iron deposition was elevated in cortex and hippocampus (P<0.01), mitochondrial membrane density increased, the cristae was broken or reduced, and the outer membrane ruptured. The levels of Fe²⁺ and MDA, as well as the mean flourscence intensity of ROS were elevated (P<0.01) and the level of GSH was reduced (P<0.01). The mRNA and protein expression of GPX4 and SLC7A11 was reduced (P<0.01), while that of p53 rose (P<0.01). When compared with the model group, in the agonist group, the neurological deficit score was reduced (P<0.05), the percentage of infarction volume was higher (P<0.01), the histopathological damage was further exacerbated, and the percentage of iron deposition increased in the cortex and hippocampus (P<0.01). The mitochondrial quantity decreased, the membrane density increased, the mitochondrial cristae were broken or reduced, and the outer membrane was ruptured. The levels of Fe²⁺ and MDA, as well as the mean flourscence intensity of ROS were higher (P<0.01, P<0.05) and the level of GSH was reduced (P<0.05). The mRNA and protein expression of GPX4 and SLC7A11 decreased (P<0.01, P<0.05), while that of p53 was elevated (P<0.01). Besides, in comparison with the model group, the neurological deficit score was higher in the acupuncture group and the acupuncture + agonist group (P<0.01, P<0.05), the percentage of cerebral infarction volume was lower in the acupuncture group (P<0.01), the pathological damage of brain tissue was alleviated in the acupuncture group and the acupuncture + agonist group, and the percentage of iron depositiondecreased in the cortex and hippocampus (P<0.01). The mitochondrial structure was relatively clear, the mitochondrial cristae were fractured or reduced mildly in the acupuncture group and the acupuncture + agonist group. The levels of Fe²⁺ and MDA, as well as the mean flourscence intensity of ROS were lower (P<0.01) and the level of GSH was higher (P<0.01) in the acupuncture group. The mean fluorescence intensity of ROS were dropped (P<0.01) in the acupuncture + agonist group. The mRNA expression of GPX4 and SLC7A11 was elevated (P<0.01) and that of p53 was reduced (P<0.01, P<0.05) in either the acupuncture group or the acupuncture + agonist group; the protein expression of GPX4 and SLC7A11 rose (P<0.05, P<0.01) and that of p53 was dropped (P<0.01) in the acupuncture group; and the protein expression of p53 was also lower in the acupuncture + agonist group (P<0.05). When compared with the agonist group, in the acupuncture + agonist group, neurological deficit score increased (P<0.01), the percentage of cerebral infarction volume decreased (P<0.01), the pathological brain tissue damage was reduced, the percentage of iron deposition in cortex and hippocampus decreased (P<0.01), the mitochondrial structure was relatively clear and the cristae broken or reduced slightly; the levels of Fe²⁺ and MDA, as well as the mean fluorescence intensity of ROS were dropped (P<0.01), while the level of GSH increased (P<0.05); the mRNA and protein expression of GPX4 and SLC7411 was elevated (P<0.01, P<0.05), and that of p53 reduced (P<0.01).

Objective To analyze the composition of the aqueous extract of Polygonatum Cyrtonema Hua(PCHE)and evaluate its antitumor activity in vitro and in vivo.Our aim is to provide a theoretical basis for the further development and utilization of Polygonatum Cyrtonema Hua.Methods(1)PCHE was prepared by aqueous extraction,and the chemical composition of PCHE was analyzed by UPLC-Q-TOF/MS and phenol-sulfuric acid method.The inhibitory activity on tumor cells proliferation of PCHE was detected by CCK-8 assay.Cell cycle and apoptosis were detected by flow cytometry,and the expression of apoptosis-related proteins Bcl-2 and Bax was detected by Western Blot.The inhibitory activity of PCHE-containing serum on cell proliferation was detected.(2)A B16 tumor-bearing mice model was constructed and model mice were randomly divided into the model group(saline),the positive drug group(CTX:50 mg·kg-1),and PCHE low-,medium-,and high-dose groups(55.9,111.8,223.6 mg·kg-1),and treated by gavage for 7 days.Changes in body weight and tumor volume of mice were observed during the treatment period.The mice were executed after the treatment,and the histopathological changes of heart,liver,spleen,lung,kidney and tumor were observed by hematoxylin-eosin(HE)staining.The protein expression of Bcl-2 and Bax in tumor tissues was detected by immunohistochemistry(IHC).Results The polysaccharide content of PCHE reached(10.07±1.3)%,and the flavonoid content was(0.044±0.004)%,and thirty-nine components were detected by UPLC-Q-TOF/MS,which contained antitumor components such as flavonoids(baicalein,quercetin,luteolin and rutin),organic acids(ferulic acid)and polyphenols(gallic acid),etc.PCHE exhibited the inhibitory effects on Hela,A549,4T1,B16,MFC and HepG2 cells,among which the inhibitory effect on B16 cells was the most significant(P＜0.001),and PCHE induced cell cycle arrest at G0/G1 phase in B16 cells(P＜0.001).The results of double-staining flow cytometry and Western Blot showed that PCHE significantly promoted apoptosis of B16 cells,decreased the expression of Bcl-2,and promoted the expression of Bax(P＜0.01,P＜0.001).and PCHE constituents absorbed into blood also had an inhibitory effect on B16 cells(P＜0.001).In addition,the results of in vivo activity assay showed that different doses of PCHE could inhibit tumor growth,induce tumor cell necrosis,reduce Bcl-2 expression,and increase Bax expression compared with the model group.Conclusion The ingredients in PCHE are abundant.It contains a variety of antitumor active ingredients,which can inhibit tumor growth,induce tumor cell apoptosis,show strong anti-tumor effects and be worthy of in-depth study.

Objective:To explore the effect of ultrasound-guided superficial cervical plexus block on chronic pain after intracranial space-occupying resection by suboccipital retrosigmoid approach.Methods:A single-center, randomized, double-blind, parallel controlled trial was conducted on 106 consecutive patients who underwent selective resection of acoustic neuromas in the cerebellopontine angle through the suboccipital retrosigmoid approach in Beijing Tiantan Hospital, Capital Medical University from November 2019 to April 2021. The patients were divided into experimental group and control group by random number table method, with 53 cases in each group. The patients in experimental group underwent superficial cervical plexus block with 0.5% ropivacaine under ultrasound-guided, and the patients in control group received an equal volume of 0.9% sodium chloride. Three months after surgery, the patients were followed up for chronic postoperative pain and the chronic postoperative pain rating scale (NRS) score via telephone. The nature of chronic pain was evaluated using the short-form McGill pain questionnaire-2 (SF-MPQ-2).Results:The incidence of chronic postoperative pain and the NRS score of chronic postoperative pain in experimental group were slightly lower than those in control group: 39.6% (21/53) vs. 50.9% (27/53) and 0 (0, 2) scores vs. 1 (0, 3) scores, but there were no statistical difference between the two groups ( P>0.05). There were no statistical difference in SF-MPQ-2 various scores and total score after surgery between the two groups ( P>0.05). Conclusions:Ultrasound-guided superficial cervical plexus block has a certain analgesic effect on chronic pain after intracranial space-occupying resection by suboccipital retrosigmoid approach, but it still requires further verification through an adequate sample size.

The aim of this study was to investigate the correlation between porcine epidemic diar-rhea virus(PEDV)S1 IgG antibody levels and neutralizing antibody potency in sow sera.Sera from 5 PEDV-infected farms with a clear immune background,5 non-infected farms and 5 infected farms with an unclear immune background,and sera from return-fed reserve pigs,totaling 716 copies,were collected and measured,and the correlation between PEDV S1 IgG antibodies and neutralizing antibodies was analyzed.The results showed that the PEDV S1 IgG and neutralizing antibodies of sow sera showed highly significant positive correlation,the correlation coefficient was 0.892(P＜0.000 1).Previous studies have shown that the level of PEDV neutralizing antibodies in sow serum correlates with the ability of piglets'maternal antibodies to resist PEDV infection.Therefore,the a-bility of maternal antibodies against PEDV in piglets can be evaluated by detecting PEDV S1 IgG antibodies in the serum of sows.In 10 PEDV-infected farms,the neutralizing antibodies to PEDV in the sera of sows after immunization were generally high,and the S1 IgG antibodies were also high,and their S/P values were higher than 3.5 in 66.9％of the farms(347/519),and the highest anti-body levels were found in the four farms in which PED did not occur,whereas the neutralizing an-tibodies in the immunized sows in the five PEDV-uninfected farms were generally low,and their S1 IgG antibodies were also low,and only 8.1％(13/161)having S/P values higher than 3.5.The re-sults suggest that most sows in PEDV-infected farms can provide good immunoprotection to pig-lets after immunization,while pigs in PEDV-uninfected farms need further immunization if they need to achieve a higher level of immunoprotection.The present study provides a substantial clini-cal basis for the use of PEDV S1 IgG antibody levels to assess the effectiveness of PEDV antibody protection in swine herds.

Objectives:To compare the diagnostic efficacy of non-ST-segment elevation myocardial infarction (NSTEMI) and the predictive value for major adverse cardiovascular events (MACE) of the 0/3-hour algorithm for high-sensitivity cardiac troponin (hs-cTn) recommended by the 2015 European Society of Cardiology (ESC) guidelines for the management of non-ST-segment elevation acute coronary syndrome (NSTE-ACS) and the 2021 "Chinese Expert Consensus on Laboratory Testing and Clinical Application of Cardiac Troponin" in suspected acute coronary syndrome (ACS) patients in the Chinese population. Methods:This is a multicenter prospective observational study,including 1527 patients with suspected ACS from three clinical centers from January 2017 to September 2020.Plasma hs-cTnI levels were measured using the ARCHITECT assay at the time of presentation and 3 hours later in patients with suspected ACS (test determination).Clinical judgment (independent clinical judgment by cardiac experts,independent of the test results) was used as the gold standard to compare the sensitivity,specificity,and consistency of the two diagnostic algorithms,and to analyze their predictive value for MACE at 30 days and 180 days.MACE in this study was defined as a composite event of cardiovascular death,myocardial infarction,and unplanned coronary revascularization. Results:According to clinical judgment,there were 400 patients with NSTEMI and 1127 patients without NSTEMI.The 0/3-hour algorithm recommended by the 2021 Chinese Expert Consensus showed higher sensitivity in diagnosing NSTEMI than the 2015 ESC guidelines (91.50％[95％ CI:88.32％-94.04％]vs.87.75％[95％ CI:84.13％-90.80％]),but slightly lower specificity (93.88％[95％ CI:92.32％-95.21％]vs.95.56％[95％ CI:94.19％-96.69％]),with both differences being statistically significant (both P<0.001).In the follow-up at 30 days and 180 days,the incidence of MACE in patients diagnosed with NSTEMI by both algorithms was higher than in those without NSTEMI (P<0.001).The incidence of MACE at 30 days and 180 days for the group excluded from the diagnosis of NSTEMI by 2015 ESC guidelines was 0.19％ and 1.120％,respectively,and for the NSTEMI group was 2.89％ and 3.68％,respectively;for the group excluded from NSTEMI by the 2021 Chinese Expert Consensus,the incidence was 0.096％ and 0.770％,respectively,and for the NSTEMI group was 2.91％ and 4.36％,respectively.Cox analysis showed that the HR ratio for MACE at 180 days in the NSTEMI group diagnosed by both algorithms was 3.418 and 5.892,respectively,significantly higher than the group excluded from NSTEMI. Conclusions:The 0/3-hour algorithm recommended by the 2021 Chinese Expert Consensus has superior diagnostic sensitivity compared to the 2015 ESC NSTE-ACS guidelines,at the cost of slightly lower specificity.Both algorithms can effectively predict MACE within 180 days,but based on the data from this study,the algorithm recommended by the 2021 Chinese Expert Consensus is more sensitive in predicting the risk of MACE,and patients excluded from the diagnosis of NSTEMI by this method have a lower incidence of MACE,suggesting that its application in clinical practice may be more helpful in terms of long-term safe management of patients.

Objective To explore the trajectory and influencing factors of joint awareness after total knee arthroplasty.Methods With the method for convenience sampling,patients who met the standards for total knee arthroplasty from July 2021 to March 2022 were selected.General information,severity of osteoarthritis,anxiety and depression,and self-efficacy were investigated before surgery(T0).Joint awareness was investigated at 1 month(T1),3 months(T2),and 6 months(T3)after surgery,respectively.Latent growth curve model was used to describe the overall trend of joint awareness;latent class growth model was used to analyze latent subgroups;logistic regression analysis was used to determine the impact of related variables on the trajectory of joint awareness.Results The scores of joint awareness were(32.70±5.80),(47.67±4.67)and(61.53±7.81)respectively at T1 to T3,and joint awareness showed an increasing trend(P＜0.001).The trajectory of joint awareness was divided into 2 potential subgroups:the rapid growth group(61.83％)and the slow growth group(38.17％).Age,BMI,other chronic diseases or not,years of osteoarthritis,severity of osteoarthritis,anxiety,depression,and self-efficacy affected the trend of joint awareness(all P＜0.05).Conclusion Joint awareness showed a linear growth trend with the postoperative time,and there were 2 potential subgroups in the trajectory.Medical workers could develop corresponding interventions based on the influencing factors to improve patients'postoperative awareness of artificial joints.

Objective:To analyze the clinical features and immunotherapy responsiveness of patients with myelin oligodendrocyte glycoprotein immunoglobulin G-antibody associated disease (MOGAD) with epilepsy, and display the risk factors of epilepsy in MOGAD.Methods:Eighty-nine patients with MOGAD diagnosed at the First Affiliated Hospital of Zhengzhou University between October 2019 and May 2023 were enrolled and classified into 2 groups upon MOGAD with ( n=29) or without epilepsy ( n=60). The Expanded Disability Status Scale (EDSS) and Clinical Assessment Scale for Autoimmune Encephalitis (CASE) were used for evaluation of severity, and EDSS or CASE scores on the 30th day after first-line immunotherapy initiation lower than that on admission were defined as well treatment responsiveness. The differences of general data, clinical manifestations, cerebrospinal fluid (CSF) and peripheral blood biochemical examination results, and immunotherapy reactivity between the 2 groups were thoroughly explicated. In addition, the risk factors of epilepsy in MOGAD were analyzed by univariate and multivariate Logistic regression analysis. Results:Compared with patients with MOGAD without epilepsy, patients with MOGAD with epilepsy were characterized by lower age of onset [24.5(10.3, 34.0) years vs 11.0(6.5, 20.0) years, Z=-2.348, P=0.019], higher percentage of male patients [43.3%(26/60) vs 75.9%(22/29), χ 2=8.326, P=0.004], higher virus infection rate [28.3%(17/60) vs 51.7%(15/29), χ 2=4.645, P=0.031], higher incidence of prodromal symptoms [11.7%(7/60) vs 34.5%(10/29), χ 2=6.586, P=0.010], higher blood-brain barrier breakdown rate [35.0%(21/60) vs 58.6%(17/29), χ 2=4.458, P=0.035], higher percentage of CSF albumin level>450 mg/L [48.3%(29/60) vs 75.9%(22/29), χ 2=6.056, P=0.014] and higher creatine kinase level [45.50(28.50, 69.75) U/L vs 57.50(41.75, 97.25) U/L, Z=-2.349, P=0.019]; more epilepsy [0(0) vs 29/29 (100.0%), χ 2=89.000, P<0.001] and disturbance of consciousness [0(0) vs 6/29(20.7%), χ 2=10.224, P=0.001] as clinical manifestations, and more cerebral cortex lesions [30/60(50.0%) vs 25/29(86.2%), χ 2=10.856, P=0.001] on magnetic resonance imaging. Nevertheless, the patients with MOGAD without epilepsy were featured with more visual impairment [23/60(38.3%) vs 3/29(10.3%), χ 2=7.406, P=0.007], limb weakness [18/60(30.0%) vs 1/29(3.4%), χ 2=8.209, P=0.004], sensory disturbance [15/60(25.0%) vs 0(0), Fisher exact probability test, P=0.002] and more cervical cord lesions [22/60(36.7%) vs 4/29(13.8%), χ 2=4.946, P=0.026] on magnetic resonance imaging. Immunotherapy responsiveness was relatively poor in the MOGAD with epilepsy group [EDSS score lower than that on admission: 15/29(51.7%) vs 46/60(76.7%), χ 2=5.641, P=0.018; CASE score lower than that on admission: 16/29(55.2%) vs 47/60(78.3%), χ 2=5.072, P=0.024] compared with the MOGAD without epilepsy group. Male was the independent risk factor of epilepsy in MOGAD ( OR=7.078, 95% CI 1.709-29.326, P=0.007). Conclusions:Compared with patients with MOGAD without epilepsy, patients with MOGAD with epilepsy reported more male patients, lower age of onset and higher incidence of prodromal symptoms, blood-brain barrier dysfunction rate, virus infection rate, CSF albumin level and creatine kinase level; clinical phenotypes were mainly meningoencephalitis and more cerebral cortex lesions were shown on magnetic resonance imaging. MOGAD with epilepsy was closely related to poor immunotherapy responsiveness, and gender was found to be the independent risk factor for epilepsy in MOGAD.

Objective:To investigate the effect of Shenfu injection on serum pepsinogen (PG) Ⅰ, PG Ⅱ and gastrin 17 (G17) in sepsis patients with acute gastrointestinal injury (AGI).Methods:From June 2021 to December 2022, a single-center randomized controlled clinical study was conducted to select patients with sepsis complicated with acute gastrointestinal injury (AGI) admitted to the ICU of the Affiliated Hospital of Xuzhou Medical University. Patients were randomly (random number) divided into Shenfu group and control group. All patients were given routine treatment of sepsis according to the guidelines, including treatment of primary disease, fluid resuscitation and supportive management. The Shenfu group was treated with Shenfu injection at the same time as routine treatment. The gastrointestinal injury indicators (PGⅠ, PGⅡ, G17 and AGI grades) before treatment and on the 3rd and 7th days of treatment, and duration of mechanical ventilation and length of ICU stay of the two groups were recorded and compared.Results:A total of 89 sepsis patients with AGI were enrolled, including 44 patients in the Shenfu group and 45 patients in the control group. Before treatment, there was no statistically significant difference in serum PGⅠ, PGⅡ, and G17 between the two groups of patients (all P>0.05). On the 3rd day of treatment, the serum PGⅠ levels in the Shenfu group were significantly lower than the control group [(156.46±62.90) μg/L vs. (183.03±45.44) μg/L, P<0.05]. There was no statistically significant difference in serum PGⅡ and G17 levels between the two groups (both P>0.05). On the 7th day of treatment, the serum levels of PG I, PG II, and G17 in the Shenfu group were significantly lower than those in the control group [(107.97±23.18) μg/L vs. (154.78±33.11) μg/L, (10.73±5.62) μg/L vs. (13.83±6.30) μg/L, (7.31±3.20) pmol/L vs. (9.29±3.92) pmol/L, all P<0.05]. The AGI grading, duration of mechanical ventilation, and length of ICU stay in Shenfu group were significantly reduced than those in the control group (all P<0.05). Conclusion:Shenfu injection can improve the serum gastric function, lower AGI grading, reduce mechanical ventilation time, and the length of ICU stay in sepsis patients with AGI.
