BACKGROUND:Exercise as a form of active rehabilitation can improve the dysfunction caused by peripheral nerve injury,and different exercise modalities target different lesion sites and recovery mechanisms. OBJECTIVE:To comprehensively analyze the application and mechanisms of different exercise modalities in functional recovery from peripheral nerve injury. METHODS:A computerized search was conducted in PubMed and CNKI databases for relevant literature published before January 2024.The search terms used were"peripheral nerve injury,spinal cord,exercise,cerebral cortex,muscle atrophy,mirror therapy,blood flow restriction training"in both English and Chinese.Finally,77 articles were included for review. RESULTS AND CONCLUSION:Peripheral nerve injury can cause systemic pathological changes such as skeletal muscle atrophy,corresponding spinal cord segmental lesions,and sensorimotor cortex remodeling.Aerobic exercise can improve dysfunction by enhancing the immune response,promoting glial cell polarization,and promoting the release of nerve growth factor.Blood flow restriction exercise can regulate the secretion of muscle growth factor,promote muscle growth and enhance muscle strength.Mirror movement has a good effect in activating the cerebral cortex and reducing cortical remodeling.Different exercise modalities have potential benefits in functional recovery after peripheral nerve injury;however,there are still some problems and challenges,such as the choice of exercise modalities,the control of exercise intensity and frequency,and the detailed analysis of mechanisms.

Aromatic Chinese medicinal essential oils are volatile oils extracted from aromatic Chinese herbs， which can prevent and treat respiratory infectious diseases through multiple synergistic mechanisms including pathogen inhibition， immune regulation， and inflammatory response regulation. Essential oils are primarily used externally on the body to prevent infections and alleviate symptoms through methods like inhalation， smearing， topical application， bathing， gargling or as a suppository. They can also be utilized in the environment for disinfection and air purification， through methods like diffusion， vaporization， or spraying. The external application of essential oils extracted from Chinese aromatic herbs has the advantages of convenience， quick absorption， and simultaneous influence on both the body and mind. However， there are still challenges and deficiencies in aspects such as the positioning of functions， indications， safety， and the research on the mechanism of action. It has been proposed to combine the theory of aromatic Chinese medicinals with the characteristics of essential oils， and formulate prescriptions of Chinese medicinal essential oils under the principles of traditional Chinese medicine syndrome differentiation， and prevent and treat respiratory infectious diseases efficiently， accurately， and safely， thereby expanding the clinical application of aromatic Chinese medicinals and the preventive theory of traditional Chinese medicine.

ObjectiveTo compare the effectiveness and mechanism of Xiangzhu Fanggan Formula （香术防感方） by sniffing and nasal drops for preventing influenza A H1N1flu. MethodsFifty-six BALB/c mice were randomly divided into normal group， model group， zanamivir group， high-concentration sachet group， low-concentration sachet group， high-concentration nasal drops group， and low-concentration nasal drops group， with 8 mice in each group. In the low- and high-concentration sachet groups， 15 g and 30 g of Xiangzhu Fanggan Formula sachet were used for sniffing for 24 h per day； while in the low- and high-concentration nasal drops groups， nasal drops of Xiangzhu Fanggan Formula were given at a concentration of 0.11 and 0.22 g/ml， 20 μl each time， twice a day； in the zanamivir group， zanamivir was given at a concentration of 1.025 mg/ml of 20 μl each time， twice a day； in the normal group and the model group， nasal drops of normal saline were given at 20 μl each time， twice a day. Each group was given prophylactic intervention for 5 days. On day 5， 1 h after the administration of the drug， the mice in all groups except the normal group received 35 μl of 50 LD₅₀ A/PR/8/34/H1N1 viral solution as nasal drops to prepare influenza A H1N1 model mice. The body mass of the mice was recorded and the rate of change of body mass was calculated daily from day 5 to day 9 of the experiment， and the general status was observed. The mice were sampled on day 9， and the lung index and the inhibition rate of lung index were calculated； HE staining was used to detect pathological changes in lung tissues and to score lung tissue lesions； RT-qPCR was used to detect viral load in lung tissues； and ELISA was used to detect secretory immunoglobulin A （sIgA） and serum tumour necrosis factor α （TNF-α） and interleukin 2 （IL-2）， interleukin 6 （IL-6）， and interferon γ （IFN-γ） in the lavage fluid of the upper respiratory tract. ResultsOn days 7， 8 and 9 of the experiment， the rate of change in body mass of mice in the model group significantly lower than that in the normal group at the same time points （P＜0.05 or P＜0.01）. On days 8 and 9 of the experiment， the rate of change in body mass of mice in the zanamivir group and the high-concentration nasal drops group increased when compared with the model group （P＜0.05 or P＜0.01）. Compared with the normal group， mice in the model group had significantly higher lung index， lung tissue lesion score， lung tissue viral load， significantly higher serum TNF-α， IL-6， IL-2， IFN-γ levels， and significantly lower sIgA levels in the upper respiratory lavage fluid （P＜0.01）. Compared with the model group， the lung index and lung tissue viral load reduced， serum IFN-γ， TNF-α， IL-2， IL-6 levels reduced， and sIgA levels increased in the zanamivir group and the high-concentration nosal drops group （P＜0.05 or P＜0.01）； except for low-concentration sachet group， lung tissue lesion scores of the drug intervention groups reduced compared with those of the model group （P＜0.01）. Compared with the zanamivir group， the lung index increased in the low-concentration sachet group and the low- and high-concentration nasal drops groups， and the serum TNF-α and IL-2 levels increased in all Xiangzhu Fanggan Formula intervention groups （P＜0.05 or P＜0.01）. Compared with high-concentration nasal drops group， serum TNF-α and IFN-γ levels elevated in the high-concentration increased group， and lung tissue viral load elevated in the low-concentration nasal drops group （P＜0.05 or P＜0.01）. The lung index inhibition rate was 80.84% in the zanamivir group， 41.61% and 17.90% in the high- and low-concentration sachet groups， and 35.40% and 25.40% in the high- and low-concentration nasal drops groups， respectively. HE staining showed that the lung tissues of the model group showed thickening of alveolar septa， alveolar collapse， and infiltration of inflammatory cells； whereas， in each drug intervention group， the inflammation of the lung tissues of the mice and the damage reduced， and the most obvious improvement was in the zanamivir group and the high-concentration nasal drops group. ConclusionXiangzhu Fanggan Formula by sniffing and nasal drops could both prevent influenza A H1N1 virus infection， with antiviral and anti-inflammatory effects， also could improve the pathological damage of lung tissue， and improve the immunity of respiratory mucosa. The nasal drops may be better than sachets in inhibiting inflammatory response， especially the high-concentration nasal drops showed more effective.

Objective To investigate the clinical application value of transumbilical single-port laparoscopic ovarian cyst excision with protection of ovarian function.Methods From July 2018 to December 2019,we performed 56 cases of single-port laparoscopic ovarian cyst debulking,in which the umbilicus was incised transversely for about 2 cm and a single-port trocar puncture was placed to form an artificial pneumoperitoneum.The ultrasonic knife was used to avoid the ovarian hilum and cut the ovarian cortex on the opposite side of the ovary to ensure a good blood supply.The ovary on the affected side was fixed to facilitate blunt separation of the cyst and preserve the normal tissues of the ovary as much as possible.The 2-0 absorbable suture was applied for hemostasis and ovarian reconstruction.Results The operations were successfully completed in all the 56 cases,including bilateral ovarian cyst excision in 3 cases,salpingectomy in 3 cases,tubal mesangial cyst excision in 1 case,hysteromyomectomy in 2 cases,appendectomy in 1 case(an additional puncture hole was added due to the need for abdominal drainage after the operation),hysteroscopic resection of endometrial polyps in 1 case,and pelvic adhesion release in 1 case.The operation time was(72.0±30.0)min,and the postoperative hospitalization time was(5.0±0.6)d.No complication occurred.The 56 patients were followed up for 2-3 years,with an average of 1.5 years,with no complications,poor wound healing,or recurrence of ovarian cysts.There was no significant difference in the number of ovarian antral follicles between 6 and 12 months after surgery and before surgery[7.02±1.57 vs.7.05±1.55,P = 1.000;6.93±1.46 vs.7.05±1.55,P =1.000].There was no significant difference in ovarian stromal blood flow(P>0.05),indicating no decrease in ovarian function.Conclusion The key to protecting ovarian function is the rational selection of surgical instruments and incisions,precise performance of resection of ovarian cysts,and protection of ovarian blood supply.

Objective:To explore the brain activation intensity changes of depressed patients in the phase of expected value (EV), positive prediction error (+ PE) and negative prediction error (-PE) under uncertain (risky, ambiguous) decision-making.Methods:From July 2018 to February 2021, a total of 48 depressed patients in the Affiliated Hospital of Qingdao University were collected (depression group), and 69 sex-, age-, and educational level-matched healthy people were recruited as the control group. All participants completed risky and ambiguous decision-making tasks under the E-Prime system.SA-9800 brain functional audio-visual stimulation system and GE3.0 T functional magnetic resonance imaging (fMRI) scanners were used to conduct synchronous scanning and data acquisition. Using Xjview software to analyze the activation intensity of related brain areas to compare the activity intensity of the two groups.SPSS 16.0 software was used for chi square test, independent sample t-test. Results:Under risky decision-making, compared with the control group, the brain areas with reduced activation during EV phase in depression group were bilateral prefrontal cortex (PFC)(MNI coordinate: left x=-45, y=21, z=-6; right x=0, y=69, z=-3), left para hippocampal gyrus(PHG)(MNI coordinate: x=-9, y=0, z=-22), bilateral occipital lobe(OL)(MNI coordinate: left x=-51, y=-81, z=-3; right x=48, y=-84, z=-9)( P<0.05). The brain areas with reduced activation during + PE phase were bilateral PFC, left hippocampus (HIP), bilateral temporal lobe (TL), left middle occipital gyrus( P<0.05). The brain areas with reduced activation were bilateral PFC, right putamen, bilateral TL( P<0.05) during -PE phase. Under ambiguous decision-making, compared with the control group, the brain areas with reduced activation during EV phase in depression group were bilateral PFC, right OL( P<0.05); the brain areas with reduced activation during + PE phase were bilateral PFC, right putamen and hippocampus, bilateral TL, bilateral OL( P<0.05); and the brain areas with reduced activation were bilateral PFC, bilateral TL( P<0.05) during -PE phase. Conclusion:The study shows that the activities of reward brain areas such as PFC, limbic system and OL system are reduced during EV and PE phase under uncertain decision-making in depressed patients.

Objective:To employ qualitative research methods to evaluate the sustainability of the Shandong-Ministry of Health Action on Salt and Hypertension (SMASH) interventions and their influencing factors.Method:In September 2023, interviewees meeting the inclusion criteria were recruited through purposive sampling in Jinan, Shandong Province. A semi-structured interview guide was designed based on the CFIR and RE-AIM frameworks. Personal in-depth interviews and focus group discussions were conducted to gather insights on the feasibility, effectiveness, and sustainability of the project interventions from various stakeholders, including representatives from the government, food manufacturers, restaurants, academia, and residents.Results:A total of 15 individuals participated in in-depth interviews, involving six representatives from food manufacturers, four from restaurants, three from the government, and two from academia. There were four focus group discussions with 30 residents. The study found that at the individual resident level, health awareness and the availability of sodium reduction tools in the market could affect their salt reduction practices. For food manufacturers and restaurants, consumers′ preferences, technical challenges in reformulation, and government support were key factors determining the smooth progress of their salt reduction efforts. At the governmental level, multi-sectional coordination, chronic disease management demonstration areas, and the impact of the pandemic were the main factors influencing the implementation of sodium reduction interventions.Conclusion:Future endeavours should strengthen long-term management and optimise the complex influencing factors associated with intervention measures. This will be essential in sustaining and expanding the positive health outcomes achieved through the Shandong population sodium reduction strategy.

Objective To investigate the protective effect and mechanism of ginsenoside Rg1(G-Rg1)on interleukin-6(IL-6)-induced neuronal injury in rats by regulating Janus activated kinase(JAK)/signal transducer and activator of transcription 3(STAT3)signaling pathway.Methods After culture,rat hippocampal neurons were divided into the control group(normal culture),the IL-6 model group(50 μg/L IL-6 was used to treat rat hippocampal neurons for 18 h to simulate the inflammatory environment in brain),the G-Rg1 low dose(10 μmol/L)group and the G-Rg1 high dose(40 μmol/L)group.After 48 h of normal culture,the survival rate of hippocampal neurons was determined by MTT method.The total iron load of neurons was detected by spectrophotometry,and levels of ferroptosis markers glutathione(GSH)and glutathione peroxidase 4(GPX4)were detected.The mRNA expression level of ferroportin 1(FPN1)in hippocampal neurons was detected by qRT-PCR.The expression of proteins related to the neuronal JAK/STAT3 signaling pathway was detected by Western blot assay.Results Compared with the CON group,the neuronal survival rate,GSH content,GPX4 content and FPN1 mRNA expression level were decreased in the IL-6 model group,and the total iron load,p-JAK and p-STAT3 protein expression levels were increased(P＜0.05).Compared with the IL-6 model group,the neuronal survival rate,GSH content,GPX4 content and FPN1 mRNA expression level were increased in the low-dose and high-dose G-Rg1 groups,and the total iron load,p-JAK and p-STAT3 protein expression levels were decreased(P＜0.05).Changes of the above indicators were more significant in the high-dose G-Rg1 group than those in the low-dose G-Rg1 group(P＜0.05).Conclusion The mechanism of G-Rg1 alleviating ferroptosis of hippocampal neurons in rats may be related to the inhibition of IL-6/JAK/STAT3 signaling pathway,up-regulation of FPN1 expression,and prevention of iron overload.
