Liver cirrhosis is a common chronic progressive liver disease， and such patients often have coagulation disorders， which may lead to thrombotic and hemorrhagic events. While traditional anticoagulant therapies have various limitations， the emergence of novel oral anticoagulants （NOAC） provides new options for anticoagulation treatment in patients with liver cirrhosis. This article comprehensively reviews the application of NOAC in patients with liver cirrhosis， discusses their advantages and potential risks， analyzes their pharmacokinetic and pharmacodynamic characteristics， and evaluates their efficacy and safety in the prevention and treatment of cirrhosis-associated thrombosis based on clinical evidence， in order to provide a reference for clinical decision-making.

Objective : To investigate the selective activation of 5-hydroxytryptamine neurons in the dorsal raphe nucleus(DRN5-HT) of rats with insomnia induced by p-chlorophenylalanine(PCPA) using chemical genetics techniques, and to explore whether it has a regulatory effect on comorbidities of insomnia and anxiety. Methods : 32 male SD rats were randomly divided into control group, PCPA model group(PCPA group), chemical activation group(hM3Dq+CNO group), and chemical control group(hM3Dq+Saline group). The anxiety level of experimental rats was evaluated through open field experiments and elevated cross maze experiments.In vivoelectroencephalography(EEG) was used to record propofol induced sleep and cortical EEG changes, and immunofluorescence staining was used to observe changes in c-Fos positive protein expression in 5-HT neurons. Results : The behavioral results showed that compared with the chemical control group, the anxiety level of the chemical activation group was significantly lower(P<0.05), and sleep duration was significantly prolonged(P<0.05). The expression level of c-Fos positive protein in DRN5-HT neurons in the chemical activation group was higher(P<0.05). The EEG results showed that the percentage of δ-band power between the chemical activation group and the chemical control group was higher(P<0.05), the power percentage in the α-band was relatively low(P<0.05). Conclusion Chemical activation of 5-HT neurons in the DRN region can improve anxiety levels and increase sleep duration in PCPA induced insomnia rats.

Objective To prepare a thermosensitive hydrogel scaffold loaded with bone marrow mesenchymal stem cells（BMSCs） and resveratrol liposomes （RSV-LIP） to form a therapeutic unit and evaluate its treatment efficacy for traumatic brain injury （TBI）. Methods BMSCs were extracted from rats, and RSV-LIP was prepared and characterized. Cell models were constructed to investigate the pharmacological effects of BMSCs combined with RSV-LIP. BMSCs and RSV-LIP were then loaded into the hydrogel, and a TBI mouse model was established to evaluate the therapeutic effects of the hydrogel. Results The RSV-LIP had a particle size of 127.8 nm, a Zeta potential of −4.9 mV, an encapsulation efficiency of 78.50%, and a drug loading content of 2.37%. Live-dead staining indicated good biocompatibility of the hydrogel. The combination of BMSCs and RSV-LIP significantly inhibited TNF-α and reduced ROS levels, promoting cell migration in scratch assays. Compared to the control group, the hydrogel group showed significantly lower mNSS scores （P<0.01）, higher hanging scores （P<0.001）, and reduced stepping errors （P<0.001）. Conclusion The combination of BMSCs and RSV-LIP exhibited antioxidative stress, anti-inflammatory, and neurogenic cell migration-promoting effects. When loaded into a hydrogel scaffold and locally implanted, it could improve the motor and sensory functions in TBI mice.

Objective To investigate the correlation between glycemic variability metrics and the risk of diabetic foot(DF)in patients with type 2 diabetes mellitus(T2DM)utilizing flash glucose monitoring(FGM)tech-nology.Methods A retrospective analysis was conducted on 233 hospitalized patients with T2DM,with or without DF,who were treated in the Department of Endocrinology at Lianyungang First People's Hospital from January 2021 to May 2022 and monitored using FGM.Patients were categorized into a non-DF group(n=147)and a DF group(n=86)based on the presence of DF.The study compared general clinical characteristics,biochemical parameters,and glycemic variability metrics between the two groups and performed subgroup analyses.Binary logistic regression was employed to identify factors associated with the risk of DF,while receiver operating characteristic(ROC)curves were utilized to assess the predictive value of glycemic variability metrics for DF.Results Compared with the non-DF group,patients in the DF group exhibited significantly longer disease duration,higher body mass index(BMI),glycated hemoglobin(HbA1c),urinary albumin-to-creatinine ratio(UACR),alanine aminotransferase(ALT),serum uric acid(SUA),mean amplitude of glycemic excursions(MAGE),coefficient of variation(CV),mean of daily differences(MODD),and mean blood glucose(MBG),but lower fasting C-peptide(FCP),fasting insulin(FINS),high-density lipoprotein cholesterol(HDL-C),and time in range(TIR),with statistically signifi-cant differences(P<0.05).Subgroup analysis revealed that TIR was associated with the incidence of DF and diabetic retinopathy(DR).Binary logistic regression analysis identified HbA1c,MAGE,MODD,and MBG as risk factors for DF,while TIR was a protective factor(P<0.05).ROC curve analysis demonstrated that the area under the curve(AUC)for predicting DF using HbA1c,TIR,MAGE,MODD,MBG,and their combination were 0.646,0.850,0.868,0.764,0.619,and 0.967,respectively,indicating superior performance of the combined prediction model.Conclusions HbA1c,TIR,MAGE,MODD,and MBG are critical factors associated with the development of DF in patients with T2DM.Targeted early interventions aimed at optimizing these glycemic variability indicators may effectively reduce the incidence of DF.

Objective:To explore the central venous catheter maintenance compliance among nurses in Class Ⅱ and Ⅲ hospitals in Hunan Province.Methods:From January to March 2022, 297 nurses from 22 Class Ⅱ and Ⅲ hospitals in Hunan Province were selected as the research subject by convenience sampling. Nurses were surveyed using the self-made Central Venous Catheter Maintenance Compliance Questionnaire. Multiple linear regression was used to analyze the influencing factors of nurse compliance with central venous catheter maintenance, the items of the Central Venous Catheter Maintenance Compliance Questionnaire were analyzed.Results:A total of 297 questionnaires were distributed, and 268 valid questionnaires were collected, with an effective response rate of 90.24%. The hospital level, specialized training in intravenous therapy, and age were the influencing factors on the compliance of nurses with central venous catheter maintenance. Analyzing specific items, only 34.3% (92/268) of nurses correctly executed the item "alcohol cotton pads were recommended", and only 66.4% (178/268) of nurses correctly performed the item "sterile gauze dressings should be replaced at least every two days".Conclusions:There is a certain gap in the central venous catheter maintenance compliance among nurses at all levels of hospitals, and there is a need to improve compliance in disinfection of infusion joints and replacement of sterile gauze dressings. We should strengthen the training of specialist nurses, especially the training of nurses in ClassⅡ hospitals on specialized skills related to intravenous therapy.

ObjectiveTo evaluate the effectiveness of Gandou decoction （GDD） by analyzing theclinical efficacy of GDD combined with speech training on the treatment of dysarthria with endoretention of damp-heat in Wilson's disease （WD）， so as to provide more clinical data and theoretical support for the selection of appropriate treatment schemes for WD patients with dysarthria with endoretention of damp-heat. MethodA total of 60 eligible WD patients with dysarthria with endoretention of damp-heat were selected and divided into a control group and a treatment group according to the random grouping method， with 30 cases in each group. The control group was treated with speech training + sodium dimercaptopropanesulfonate （DMPS）， and the treatment group was combined with GDD on the basis of the control group， with eight days as a course of treatment for 32 days. The total clinical effectiveness rate （Goldstein clinical classification）， dysarthria grading assessment from China Rehabilitation Research Center， TCM syndrome scores， 24-hour urine copper content， and modified Frenchay dysarthria rating scale scores of the two groups were compared before and after treatment. ResultAfter treatment， the total effective rate of the observation group was 90.0% （27/30）， and that of the control group was 70.0% （21/30）. The total effective rate of the observation group was significantly higher than that of the control group （Z=-1.986，P<0.05）. After treatment， the modified Frenchay dysarthria score， dysarthria grading assessment from China Rehabilitation Research Center， and 24-h urine copper in the two groups were significantly increased （P<0.05， P<0.01）， and the TCM syndrome score was significantly decreased （P<0.01）. Compared with the control group after treatment， except for the respiratory and jaw score， the modified Frenchay dysarthria score of the observation group was significantly increased （P<0.05， P<0.01）. The dysarthria grading from China Rehabilitation Research Center and 24-h urine copper content were significantly increased （P<0.01）， and the observation group had better efficacy. During the study period， there were no serious adverse reactions such as fever， rash， oral and eyelid mucosal swelling， exfoliative dermatitis， vomiting， diarrhea， or allergic shock during copper excretion treatment of DPMS and oral administration of GDD. ConclusionGDD combined with speech training can improve the symptoms and efficacy of WD patients with dysarthria with endoretention of damp-heat and enhance the patients' living standard to a certain extent， which can be widely used in clinics.

Objective: To observe the effects of apocynum venetum leaves extract(AVLE) on anxiety-like behavior caused by chronic restraint stress(CRS). Methods: Male C57BL/6 mice were randomly divided into 4 groups, 5 per group: control group(equivalent physiological saline 0.2 ml/10 g), CRS model group(equivalent physiological saline 0.2 ml/10 g), AVLE treatment group(AVLE 120 mg/kg) and positive control group(paroxetine hydrochloride 3 mg/kg). The anxiety mouse model of chronic restraint stress was established, and the anxiety level of mice treated with apocynum venetum leaf extract was evaluated by open field test and elevated cross maze test. Immunofluorescence staining was used to detect the changes of serotonin receptor in hypothalamic paraventricular nucleus. Chemogenetics combined with adeno-associated virus was used to detect the effect of hypothalamic oxytocin neurons on the anxiety regulation of AVLE. Results: Compared with the model group, apocynum venetum leaves extract could increase the total distance of open field exercise, the activity time, the time of mice entering the central area(P<0.05), and the activity distance and time of mouse elevated maze(P<0.05). The expression of serotonin 1A receptor in the paraventricular nucleus of hypothalamus was enhanced after treatment with AVLE, and inhibition of serotonin 1A receptor and oxytocin neurons in hypothalamic paraventricular nucleus could decrease activity level in mice(P<0.05). Conclusion AVLE can improve the anxiety state and activity ability of CRS mice, and its effect is related to serotonin receptor and oxytocin neurons in hypothalamic paraventricular nucleus.

Hyperuricemic nephropathy （HN）， a secondary renal damage common in clinical practice， is characterized by early concealing and continuous progression. The understanding of HN in traditional Chinese medicine （TCM） is from a macroscopic perspective. According to the TCM theory， HN is caused by the combination of external pathogens and internal injuries， with the main pathogenesis being root deficiency combined with superficial excess and deficiency-excess in complexity. In western medicine， the understanding of HN is from the microscopic perspective， which holds that the occurrence of HN is the result of inflammation， oxidative stress， renin-angiotensin-aldosterone system （RAAS） activation， and metabolic abnormalities. The TCM syndromes of HN include internal dampness and heat， obstruction in dampness and turbidity， deficiency of spleen and kidney， and deficiency of kidney yin. Accordingly， the prescriptions should clear heat and dampness， remove dampness and turbidity， tonify spleen and kidney， and nourish kidney yin， respectively. In addition to TCM prescriptions， single herbal medicines and their extracts， Chinese patent medicines， and external applications of Chinese medicines have played a significant role in the treatment of HN， promoting the application of TCM in the treatment of HN. Moreover， the integrated traditional Chinese and western medicine has also played a role in the treatment of HN， enriching the treatment schemes of HN. Different from common kidney diseases such as acute and chronic glomerulonephritis and nephrotic syndrome， HN with particularity should be carefully differentiated in clinical practice. This article systematically summarizes the research progress in the treatment of traditional Chinese medicine and integrated traditional Chinese and western medicine on hyperuricemic nephropathy with TCM and integrated traditional Chinese and western medicine， aiming to enrich the system and theory of HN treatment and further guide the clinical practice.

Objective:To explore the effect of healthcare failure mode and effect analysis (HFMEA) management mode on perioperative nursing quality of cancer patients at arm infusion port.Methods:Using the convenient sampling, 68 cancer patients with arm infusion port in Hunan Cancer Hospital from January to October 2020 were selected as the control group, and 84 cancer patients with arm infusion port from November 2020 to August 2021 were selected as the intervention group. The control group followed the hospital's original perioperative safety management of chest wall port and peripherally inserted central catheter (PICC) insertion, while the intervention group adopted the HFMEA management mode for the perioperative safety management of arm infusion port. The risk priority number (RPN) , the occurrence of high-risk failure modes and complications of the two groups were compared.Results:The RPN values of failure modes such as inadequate preoperative evaluation, loss of intraoperative accessories, low puncture position, too short catheter clipping, loose connection between catheter and injection base, catheter positioning after incision suture, and insufficient postoperative health education in the intervention group were lower than those in the control group, with statistical differences ( P<0.05) . The incidence of inadequate preoperative evaluation, inadequate postoperative health education and postoperative complications in the intervention group were statistically lower than those in the control group ( P<0.05) . Conclusions:The HFMEA management mode can reduce the risk of perioperative links of cancer patients at arm infusion port and decrease the incidence of postoperative complications, which is worthy of clinical promotion.
