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 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 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.

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 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.

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.

As a neurological disorder in the brain, epilepsy is not only associated with abnormal synchronized discharging of neurons, but also inseparable from non-neuronal elements in the altered microenvironment. Anti-epileptic drugs (AEDs) merely focusing on neuronal circuits frequently turn out deficient, which is necessitating comprehensive strategies of medications to cover over-exciting neurons, activated glial cells, oxidative stress and chronic inflammation synchronously. Therefore, we would report the design of a polymeric micelle drug delivery system that was functioned with brain targeting and cerebral microenvironment modulation. In brief, reactive oxygen species (ROS)-sensitive phenylboronic ester was conjugated with poly-ethylene glycol (PEG) to form amphiphilic copolymers. Additionally, dehydroascorbic acid (DHAA), an analogue of glucose, was applied to target glucose transporter 1 (GLUT1) and facilitate micelle penetration across the blood‒brain barrier (BBB). A classic hydrophobic AED, lamotrigine (LTG), was encapsulated in the micelles via self-assembly. When administrated and transferred across the BBB, ROS-scavenging polymers were expected to integrate anti-oxidation, anti-inflammation and neuro-electric modulation into one strategy. Moreover, micelles would alter LTG distribution in vivo with improved efficacy. Overall, the combined anti-epileptic therapy might provide effective opinions on how to maximize neuroprotection during early epileptogenesis.
