Objective:To predict the therapeutic targets and potential mechanism of Yi medicine Tiaojing Yangyan Capsules in treating primary dysmenorrhea, menstrual disorders and oligomenorrhea using UPLC-Q-TOF-MS combined with network pharmacology.Methods:Using UPLC-Q-TOF-MS method, the chemical components in Tiaojing Yangyan Capsules were identified through automatic matching and retrieval from Waters UNIFI Chinese Materia Medica Database based on chromatographic peak retention time, precise relative molecular weight, characteristic fragment ions, and other information. TCMSP and SwissTarget Prediction databases were used to obtain chemical component targets, constructing a "drug-active component-target-disease" visual regulatory network and PPI network through databases such as GeneCards, DrugBank, TTD, PharmGKB, and Cytoscape 3.8.0 software. Metascape database was used to perform GO functional and KEGG pathway enrichment analysis on intersecting targets, and the potential mechanism of Tiaojing Yangyan Capsules in the treatment of primary dysmenorrhea was predicted.Results:Totally 67 components components were analyzed and identified from the Tiaojing Yangyan Capsules, which acted on 350 targets related to primary dysmenorrhea and menstrual disorders. The 15 main active components, including Ginsenoside Rg1, Ginsenoside Re, and Notoginsenoside Fe, targeted key proteins such as TNF, HSP90AA1, and STAT3, which would treat primary dysmenorrhea by regulating pathways such as the PI3K-Akt, FoxO, and Calcium.Conclusion:Tiaojing Yangyan Capsules may alleviate inflammatory reactions, alter hormone levels, regulate ovarian function, promote blood circulation, remove blood stasis, and regulate qi and blood through multiple components, targets, and pathways, thereby playing a preventive and therapeutic role in primary dysmenorrhea, menstrual disorders, and other conditions.

Frailty,as a clinical syndrome closely associated with age,presents mainly with a reduced reserve of multiple physiological systems,as well as a significant reduction in tolerance to stressors and resistance to stress.Debilitating people often show reduced physical function,reduced activity,and impaired cognitive and social functions.Frailty status is particularly common in elderly patients with colorectal cancer.Frailty can reduce the ability to take care of themselves,increase the risk of adverse events such as cognitive impairment,disability,fall,and death,and then affect the surgical prognosis of patients.This article aims to elucidate the research progress on the impact of frailty on the prognosis of elderly colorectal cancer surgical patients,including the concept of frailty,its pathogenesis,assessment tools,and its effects on surgical outcomes.Additionally,it will cover interventions that can be used for frailty patients undergoing surgery for colorectal cancer.The goal is to provide clinical guidance for developing standardized frailty intervention programs to improve surgical outcomes in elderly colorectal cancer patients.

Objective:To explore the effect of short-term mindfulness behavior training on body image, negative emotions and mindfulness level of pregnant women with recurrent spontaneous abortion (RSA) .Methods:From October 2020 to October 2021, 50 RSA pregnant women admitted to the Department of Gynecology of Wuxi Woman and Enfants Care Hospital were selected as the study subject using convenience sampling. Pregnant women were divided into an intervention group and a control group using a random number table method, with 25 cases in each group. During the research process, two cases were lost in the intervention group and two cases in the control group, and 46 cases were ultimately completed, with 23 cases in each group. The control group received routine nursing, while the intervention group received a 4-week mindfulness behavior training on this basis. Body Image in Pregnancy Scale (BIPS), Self-Rating Anxiety Scale (SAS), Self-Rating Depression Scale (SDS) and Mindful Attention Awareness Scale (MAAS) were used to evaluate the effect of intervention.Results:After intervention, the BIPS, SAS, SDS scores of pregnant women in the intervention group were lower than those in the control group, while the MAAS scores were higher than those in the control group, with statistically significant differences ( P<0.05) . Conclusions:Short-term mindfulness behavior training can improve the body image and negative emotions of pregnant women with RSA, and can improve the level of mindfulness attention awareness.

OBJECTIVETo observe the effects of electroacupuncture (EA) on inflammatory reaction of acute myocardial ischemia (MI) in mice, and to explore its action mechanism.

METHODSForty adult male C57BL/6 mice were randomly divided into a control group, a sham operation group, a model group and an EA group, 10 mice in each one. The model was established in the model group and EA group by ligating the left anterior descending branch of coronary artery. The mice in the EA group were treated with EA at "Neiguan" (PC 6) with 2 mA of intensity and 2 Hz /100 Hz of frequency; EA was given 30 min per treatment, once a day for totally 5 days. The mice in the control group and model group were treated with immobilization and no EA was given. The mice in the sham operation group were not treated with ligating at the left anterior descending branch of coronary artery, but the remaining procedure was identical to the model group. The electrocardiogram was recorded and △ST was calculated to evaluate the model. TTC and HE staining methods were applied to evaluate the infarct size and pathologic change of myocardial tissue, respectively. Western blot method was applied to test the protein expression levels of tumor necrosis factor-α (TNF-α), nuclear factor-κB p65 (NF-κB p65), interleukin-1β (IL-1β) and interleukin-8 (IL-8).

RESULTSCompared with the sham operation group, the S-T segments in the model group and EA group were increased obviously after modeling (both <0.01), indicating the MI model was established successfully. The TTC and HE staining results indicated, compared with the sham operation group, the model group had larger infarction size (<0.01), more myocardial fibers injury and inflammatory infiltration; compared with the model group, the infarction size of the EA group was significantly reduced (<0.01), and the myocardial fibers injury and inflammatory infiltration were improved. Compared with the control group, the protein expression levels in the sham operation group were similar (all >0.05); compared with the sham operation group, the expression levels of TNF-α, NF-κB p65, IL-1β and IL-8 were significantly increased in the model group (<0.01, <0.05); compared with the model group, the expression levels of TNF-α, NF-κB p65, IL-1β and IL-8 were significantly reduced in the EA group (all <0.05).

CONCLUSIONEA might reduce the protein expression levels of TNF-α, NF-κB p65, IL-1β and IL-8 in cardiac muscle tissue to inhibit inflammatory reaction and achieve myocardial protective effect in mice with acute myocardial ischemia.

Objective:To establish a method for the determination of omeprazole delayed release capsules and investigate the be-havior of reference preparations to provide experimental basis for generic drugs quality consistency evaluation. Methods:According to the first dissolution method (basket method) stated in 0. 931 of Chinese Pharmacopeia (2015 edition), the type of release media, solu-bility and stability of omeprazole in different media, effect of different treatment methods on the drug adsorption in the solution, differ-ent rotation speed and the methodology of ultraviolet spectrophotometry were investigated. Results:The rotation speed was 75 r·min-1 with the dissolution medium volume of 900 ml. The dissolution profiles of omeprazole delayed release capsules in three different media ( pH 6. 0 phosphate buffer, pH 6. 8 phosphate buffer and water containing 3% Tween-80) were determined with online filteration. The solubility of omeprazole in the different media was 0. 123, 0. 078 and 0. 275 mg·ml-1 , respectively. The results showed that ome-prazole was degraded 44%, 8% and 14% in 2 h in the above three release media, and degraded up to 43% in 6 h in water containing 3% Tween-80. The linear of omeprazole was 0. 209 4-20. 94, 0. 204 8-20. 48 and 0. 2016-20. 16 μg·ml-1 with the average recovery of 99.3% (RSD=0.7%,n=12), 99.7% (RSD=0.9%,n=12) and 99.5% (RSD=0.6%,n=12) respectively in the three media. Conclusion:The method is accurate and reliable, which can be used to study the quality consistency of omeprazole delayed re-lease capsules.

Objective No consensus has yet been achieved on the relationship of serum albumin with the functional out-come of acute ischemic stroke.The aim of our study was to determine whether the serum albumin level was associated with the short-term functional outcome of acute ischemic stroke in well-nourished patients. Methods Totally, 113 patients with first-ever acute ischemic stroke were recruited from Nanjing Stroke Registration Program between January and June 2015.Baseline data including de-mographic and body parameters, vascular risk factors, and laboratory results were collected.The NIH Stroke Scale ( NIHSS) was used to evaluate the severity of neurological deficits and the modified Rankin Scale ( mRS ) employed to assess the short-term functional outcome.According to the mRS at discharge, the patients were divided into a good outcome group ( mRS<3 ) and a poor out-come group ( mRS≥3 ) .The independent predictors of the short-term functional outcome were evaluated by multivariate logistic regression analysis. Results Of the 113 acute ischemic stroke patients included, 52 (46.0%) were in the good outcome group, and 61 (54.0%) in the poor outcome group.Those in the former group had a significantly higher BMI, lower serum LDL-C, lower WBC count, and lower NIHSS at admission than those in the latter .Multivariate logistic regression analysis showed that low serum albumin, NIHSS at admission, and arteriole occlusion were independent predictors of the poor short-term functional outcome ( OR=0.684, 95% CI:0.490-0.956, P=0.026). Conclusion Low serum albumin is an independent predictor of poor short-term functional outcome in acute ischemic stroke patients in well-nourished status.

Objective There is little research on the relationship of gene polymorphism of CYP2C19 and clopidogrel response after percutaneous transluminal angioplasty and stenting ( PTAS) in patients with ischemic cerebrovascular disease.The study aimed to investigate the relationship between gene polymorphism and high on-treatment platelet reactivity ( HTPR ) after PTAS and 6 months of regular dual antiplatelet administration in patients. Methods A total of 145 Chinese patients treated with PTAS in our de-partment from January 2011 to March 2014 were enrolled in this study.According to the gene sequencing, patients were divided into wild-type group(CYP2C19*1/*1,69 cases) and mutation group(heterozygous mutation CYP2C19*1/*2 and homozygous mutation CYP2C19*2/*2, 76 cases).Patients received a 100mg/d aspirin and 75mg/d clopidogrel maintenance dose (MD) as dual anti-platelet therapy after PTAS.The clopidogrel inhibition effect was measured by thrombelastography ( TEG) system 6 months after PTAS. Routine cerebral artery digital subtraction angiography was applied to evaluate whether there was restenosis in stent and logistic regres-sion analysis was used to analyze the influential factors of HTPR after PTAS and clopidogrel adminstration. Results After 6 months'regular administration of clopidogrel after PTAS, the platelet adenosine diphosphate ( ADP ) receptor inhibition rates in wild-type group, heterozygous mutation and homozygous mutation group were respectively (58.43 ±21.98)%, (47.80 ±22.93)%, (37.53 ± 21.84)%.The platelet ADP receptor inhibition rate was significantly decreased compared with wild-type group(P=0.001).Carriers of at least one CYP2C19 loss-of-function ( LOF) allele had a higher frequency of clopidogrel HTPR (35.5% vs17.4 % for patients with and without LOF alleles, respectively;P=0.014) .Using multivariate logistic regression analysis, the carriage of CYP2C19 LOF alleles was an independent predictor of the post-procedure HTPR (OR=2.356, 95% CI:1.053-5.272, P=0.037).The rate of ISR was remarkably higher in patients with at least one CYP2C19*2 alleles compared with wild-type patients(11.8%vs 1.4%, P=0.019) . Conclusion In patients with ischemic cerebrovascular disease, the CYP2C19 LOF allele had significant impact on post-procedure clopidogrel HTPR and the prognosis of ISR after PTAS.
