Traumatic brain injury (TBI) is intricately linked to the most severe clinical manifestations of brain damage. It encompasses dynamic pathological mechanisms, including hemodynamic disorders, excitotoxic injury, oxidative stress, mitochondrial dysfunction, inflammation, and neuronal death. This review provides a comprehensive analysis and summary of biomaterial-based tissue engineering scaffolds and nano-drug delivery systems. As an example of functionalized biomaterials, nano-drug delivery systems alter the pharmacokinetic properties of drugs. They provide multiple targeting strategies relying on factors such as morphology and scale, magnetic fields, pH, photosensitivity, and enzymes to facilitate the transport of therapeutics across the blood-brain barrier and to promote selective accumulation at the injury site. Furthermore, therapeutic agents can be incorporated into bioscaffolds to interact with the biochemical and biophysical environment of the brain. Bioscaffolds can mimic the extracellular matrix environment, regulate cellular interactions, and increase the effectiveness of local treatments following surgical interventions. Additionally, stem cell-based and exosome-dominated extracellular vesicle carriers exhibit high bioreactivity and low immunogenicity and can be used to design therapeutic agents with high bioactivity. This review also examines the utilization of endogenous bioactive materials in the treatment of TBI.

Objective To explore the clinical efficacy of thermosensitive moxibustion in treating headache and dizziness in patients with sympathetic type of cervical spondylosis(SCS).Methods A total of 80 patients with SCS treated in Affiliated Hospital of Jiangxi University of Chinese Medicine from June 2023 to June 2024 were selected and divided into observation group and control group according to random number table method,with 40 patients in each group.The patients in control group were treated with regular moxibustion,while the patients in observation group were treated with thermosensitive moxibustion.The clinical efficacy,pain,quality of life,cervical spine function,cervical sympathetic symptoms,and adverse reactions between two groups were compared.Results The total effective rate of observation group was significantly higher than that of control group(x2=4.501,P=0.034).After treatment,visual analogue scale(VAS),Northwick Park neck pain questionnaire(NPQ)and cervical sympathetic nerve symptom scores of patients in two groups were significantly lower than before treatment,and clinical assessment scale for cervical spondylosis(CASCS)scores were significantly higher than before treatment(P＜0.05).VAS,NPQ and cervical sympathetic nerve symptom scores of observation group were significantly lower than those of control group,and CASCS score was significantly higher than that of control group(P＜0.05).No adverse reactions such as fainting and scalding occurred in both groups during treatment.Conclusion Thermosensitive moxibustion for SCS can reduce cervical sympathetic nerve symptoms and pain,improve cervical spine function,and improve patients'quality of life,and is relatively safe.

Objective To compare the effects of bilateral and non- bilateral frontal pneumocephalus on acute agitation after craniotomy for brain tumor. Methods The clinical data of 406 brain tumor patients who had underwent craniotomy in Maoming Traditional Chinese Medicine Hospital and Guangdong Provincial People′s Hospital from January 2014 to January 2019 were retrospectively analyzed. The patients were divided into bilateral frontal pneumocephalus group (92 cases) and unilateral frontal pneumocephalus group (314 cases) according to frontal pneumocephalus within 12 hours after operation. Within 24 hours after operation, the sedation-agitation scale (SAS) was evaluated, and SAS≥ 5 scores was defined as acute agitation. Results The incidence of postoperative acute agitation, rate of postoperative sedatives use and postoperative hospital stay in bilateral frontal pneumocephalus group were significantly higher than those in unilateral frontal pneumocephalus group: 23.9% (22/92) vs. 8.6% (27/314), 14.1% (13/92) vs. 3.5% (11/314) and (12.2 ± 2.6) d vs. (8.5 ± 1.6) d, and there were statistical differences (P＜0.01 or ＜0.05). Conclusions Brain tumor patients who had bilateral frontal pneumocephalus after craniotomy are more likely to develop acute agitation.

[Objective] To investigate the value of HBV-M and HBV DNA of newborns born to HBsAg-positive mother, which were tested before combined immunization of hepatitis B. [Method] A total of 420 infants born to HBsAg-positive mothers delivered in Obstetric Department of the Third Affiliated Hospital of Sun Yat-Sen University from June 2006 to February 2008 were followed up at least 6 months and rechecked HBV-M to confirm the diagnosis of HBV intrauterine infection, which included 33 HBsAg or HBV DNA positive newborn babies and 6 newborns with both HBsAg seropositive and HBV DNA seropositive. [Result] HBV intrauterine infection rate was 0.95%. Using newborn both HBsAg positive and HBV DNA positive as diagnostic criterion to diagnose HBV intrauterine infection, the positive likelihood ratio was 208.3, while using newborn HBsAg positive or HBV DNA positive as diagnostic criterion, it was 14.3. [Conclusion] Newborn both HBsAg positive and HBV DNA positive obtained before combined immunization of hepatitis B may predict HBV intrauterine infection, and it may play as a clinical index of preliminary diagnosis of HBV intrauterine infection.

Crimes which are committed by the doctors are getting even worse on the market of medical service.And the lack of occupational morality is one of the most important reasons.Medical service and moral risk coexist to the clinical adult-students from direct medical service.Thus,to understand the importance of moral risk as well as to fully explore the internal potential of the students is a significant subject for the adult education of clinical students.

AIM and METHODS: To study the protective effects of liposomes containing L-Arg,Se and taurine on intestinal ischemia-reperfusion injury in rats. Wistar rats were divided randomly into sham operated group,ischemia-reperfusion(I/R) group,pretreatment with liposomes group and treatment with liposomes at reperfusion group. In the experiments, superior mesenteric artery was clipped for 60 min, and then unclipped. 2 hours of reperfusion later, MDA content, T-SOD and Ca 2+ -Mg 2+ -ATPase activities in intestinal tissues were detected respectively, ultrastructure and bcl-2 expression in intestinal mucosa tissue were observed. RESULTS: MDA content in liposomes-treated group was less than I/R group ( P 0.05). CONCLUSION: Liposomes containing L-arginine, Se and taurine can protect intestine against ischemia-reperfusion injury in rats,which may be related to inhibiting lipid peroxidation, stabilizing internal circumstances and inducing bcl-2 protein expression.

AIM: To investigate the protective effect of ischemic-preconditioning under the mild hypothermia against small intestine ischemia-reperfusion injury in rats and its mechanism. METHODS: Thirty-two rats were randomized into 4 groups (8 rats in each group): sham operated group (Sham), ischemia-reperfusion (I/R) group, ischemic-preconditioning (IP) group, mild hypothermia ischemic-preconditioning (MHIP) group. The wet/dry ratio, Ca 2+ -Mg 2+ -ATPase activity in intestine tissue, the malondialdehyde (MDA) content, activities of lactate dehydrogenase (LDH), superoxide dismutase (SOD) and total antioxdase (TAX) in blood were determined. Ultrastructure, Bcl-2 and Bax expression in intestinal mucosa tissue were also observed. RESULTS: After I/R, the intestinal tissue wet/dry ratio, the content of MDA, LDH activity, the optic density of Bcl-2 and Bax proteins were significantly higher in I/R group than those in sham group (P
