Osteoporosis is a common bone metabolic disease， which is mainly characterized by the decrease in the number of bone trabeculae and the destruction of bone tissue microstructure， leading to increased bone fragility and fracture risks. This disease is common in postmenopausal women， elderly men， diabetes patients， and obese people. Due to the lack of awareness to prevent bone losses and the limitations of bone mass measurement methods， osteoporosis is only concerned when there are serious complications， which imposes a heavy burden on both patients and medical resources. Oxidative stress refers to the excessive production of highly active molecules such as reactive oxygen species and reactive nitrogen in the body subjected to harmful stimuli， leading to the imbalance between the oxidative and antioxidant systems and causing oxidative damage. Studies have shown that oxidative stress can increase the generation and activity of osteoclasts and inhibit the differentiation of osteoblasts， thus playing a role in the occurrence and development of osteoporosis. Traditional Chinese medicine （TCM） is considered an effective antioxidant that can alleviate oxidative stress-induced osteoporosis by regulating a variety of signaling pathways. Studies have shown that TCM can alleviate oxidative stress and promote bone angiogenesis and osteogenesis by regulating the phosphatidylinositol 3-kinase （PI3K）/protein kinase B （Akt）， nuclear factor-kappa B， and nuclear factor erythroid 2-related factor （Nrf2） signaling pathways. TCM alleviates oxidative stress and promotes osteogenesis by regulating the Nrf2， PI3K/Akt/mammalian target of rapamycin， and secreted glycoprotein Wnt/β-catenin signaling pathways. In addition， TCM regulates NF-κB， mitogen-activated protein kinase， and receptor activator of nuclear factor kappa B （RANK）/RANK ligand/osteoprotegerin signaling pathway to alleviate excessive bone resorption induced by oxidative stress. This paper systematically summarizes the literature on the prevention and treatment of osteoporosis by TCM or its active ingredients via the above-mentioned signaling pathways to reduce oxidative stress in recent years. It briefs the possible molecular mechanisms of oxidative stress regulation-related signaling pathways to cause osteoporosis. In addition， this paper discusses the effects and mechanisms of TCM on bone angiogenesis， osteogenesis， and bone resorption by reducing oxidative stress through the regulation of related signaling pathways， aiming to provide a theoretical basis for the research and clinical treatment of osteoporosis.

OBJECTIVES: To explore the mechanism of Qingda Granules (QDG) for alleviating brain damage in spontaneously hypertensive rats (SHRs). METHODS: Twelve 5-week-old SHRs were randomized into SHR control group and SHR+QDG group treated with QDG by gavage at the daily dose of 0.9 g/kg for 12 weeks. The control rats, along with 6 age-matched WKY rats, were treated with saline only. Blood pressure changes of the rats were monitored, and pathologies and neuronal apoptosis in the cerebral cortex were examined with HE staining and TUNEL staining. Cerebral cortical expressions of miR-124 and STAT3 mRNA were detected using RT-qPCR, and the protein expressions of NeuN, STAT3, Bcl-2, Bax, and cleaved caspase-3 were detected with immunohistochemistry and Western blotting. In a HT22 cell model of oxygen and glucose deprivation/reoxygenation (OGD/R), the effects of QDG on cell viability and apoptosis, expressions of miR-124 and STAT3 mRNA, and protein expressions of STAT3, Bcl-2, Bax, and cleaved caspase-3 were evaluated using CCK8 assay, Hoechst 33342 staining, RT-qPCR, and Western blotting. RESULTS: Compared with WKY rats, SHRs had significantly elevated systolic blood pressure, diastolic blood pressure and mean arterial pressure with significantly increased neuronal apoptosis in the cerebral cortex, reduced expressions of NeuN, miR-124 and Bcl-2, and enhanced expressions of STAT3, Bax and cleaved caspase-3 (P<0.05). All these changes in the SHRs were significantly ameliorated by treatment with QDG (P<0.05). In the HT22 cell model, QDG treatment obviously reduced OGD/R-induced cell apoptosis, increased the expressions of miR-124 and Bcl-2, and suppressed the elevation of protein expressions of STAT3, Bax and cleaved caspase-3. CONCLUSIONS QDG inhibits cerebral cortical neuronal apoptosis and thereby attenuates brain damage in SHR rats by modulating the miR-124/STAT3 signaling axis.

Reach-to-grasp movements require integrating information on both object location and grip type, but how these elements are planned and to what extent they interact remains unclear. We designed a new experimental paradigm in which monkeys sequentially received reach and grasp cues with delays, requiring them to retain and integrate both cues to grasp the goal object with appropriate hand gestures. Neural activity in the dorsal premotor cortex (PMd) revealed that reach and grasp were similarly represented yet not independent. Upon receiving the second cue, the PMd continued encoding the first, but over half of the neurons displayed incongruent modulations: enhanced, attenuated, or even reversed. Population-level analysis showed significant changes in encoding structure, forming distinct neural patterns. Leveraging canonical correlation analysis, we identified a shared subspace preserving the initial cue's encoding, contributed by both congruent and incongruent neurons. Together, these findings reveal a novel perspective on the interactive planning of reach and grasp within the PMd, providing insights into potential applications for brain-machine interfaces.

Objective To explore the efficacy of bilateral facial muscle training combined with visual electromyography biofeedback on facial nerve function recovery in patients with idiopathic facial nerve palsy. Methods Patients with idiopathic facial nerve palsy admitted to Shanghai Fifth People’s Hospital, Fudan University from July 2022 to July 2024 were selected and randomly divided into a control group and an intervention group. The control group received conventional physical factor therapy, while the intervention group received bilateral facial muscle training combined with visual electromyography biofeedback therapy based on the control group’s regimen. After 20 treatment sessions, the total effective rate, the House-Brackmann (H-B) facial nerve grading system, the Sunnybrook Facial Grading System (SFGS) score, and the average value ratio of maximal amplitudes of bilateral frontalis and zygomaticus muscles were compared between the two groups. Results A total of 90 patients were included, 45 in each group. After 20 treatment sessions, the total effective rate was significantly higher in the intervention group than in the control group (84.4% vs 75.6%, P＝0.003). Compared with the control group, the intervention group demonstrated a significantly lower H-B grade (P＝0.003) and a higher SFGS score (P＝0.001). The average value ratios of maximal amplitudes of the affected versus healthy side frontalis (P＝0.013) and zygomatic (P＝0.022) muscles were higher in the intervention group than in the control group. Conclusions Bilateral facial muscle training combined with visual electromyography biofeedback is an effective approach for treating idiopathic facial nerve palsy, effectively promoting the recovery of facial nerve function, and improving facial symmetry and facial muscle function.

Objective:To analyze epidemiology of gastric cancer five-year survival distribution in Zhejiang population-based cancer registration.Methods:The follow-up data of registrated gastric cancer cases diagnosed from 2008 to 2019 in 22 national cancer registry areas of Zhejiang Province were collected and divided into three diagnostic periods: 2008-2011, 2012-2015 and 2016-2019 to calculate five-year observed survival rates (OSRs), five-year relative survival rates (RSRs) and five-year age-standardized relative survival rates (ARSRs). The distribution of population characteristics (including gender, urban/rural, age group and occupation) and clinical characteristics (including the highest diagnostic institution, sub-site, pathological type and degree of differentiation) of gastric cancer survival rates in each period were analysed.Results:51 663 new cases of gastric cancer in 2008-2019 in the cancer registration area of Zhejiang Province were included in the analysis, and the ARSR of gastric cancer in 2008-2011, 2012-2015 and 2016-2019 showed an increasing trend (39.2%, 41.3% and 44.7%, respectively). In 2016-2019, the ARSR was similar across gender and urban and rural areas (44.4% for men and 45.7% for women; 44.9% in urban areas and 44.2% in rural areas); Among people with different occupations, the ARSR was highest among business and service workers (55.3%), the agriculture, forestry, animal husbandry and fisheries, water conservancy production workers and domestic workers were lower (41.5% and 43.2%, respectively). The highest diagnostic institution was the provincial hospital with a higher gastric cancer survival rate (47.0%) than the municipal (43.4%) and district (43.6%) levels. The ARSR for gastric cancer was relatively high in the lesser curvature (59.7%), pylorus (50.4%), antrum (49.3%), and greater curvature (48.7%), and lowest in cardia (38.9%). Among the major pathological types, adenocarcinoma (NOS) had an ARSR of 48.1%, mucinous adenocarcinoma 41.3%, imprinted cell carcinoma 39.4%, and squamous carcinoma 33.4%. The ARSR for highly differentiated, moderately differentiated, poorly differentiated and undifferentiated gastric cancers were 80.6%, 57.9%, 43.2% and 36.8%, respectively.Conclusion:The 5-year survival rate of gastric cancer in Zhejiang Province is high and on the rise, with similar survival rates in different genders, urban and rural areas, and significant differences in the survival rates of gastric cancer patients with different occupational groups, highest diagnostic institutions, tumour sub-sites, pathological types and differentiation degrees.

The aim of this study was to investigate the correlation between porcine epidemic diar-rhea virus(PEDV)S1 IgG antibody levels and neutralizing antibody potency in sow sera.Sera from 5 PEDV-infected farms with a clear immune background,5 non-infected farms and 5 infected farms with an unclear immune background,and sera from return-fed reserve pigs,totaling 716 copies,were collected and measured,and the correlation between PEDV S1 IgG antibodies and neutralizing antibodies was analyzed.The results showed that the PEDV S1 IgG and neutralizing antibodies of sow sera showed highly significant positive correlation,the correlation coefficient was 0.892(P＜0.000 1).Previous studies have shown that the level of PEDV neutralizing antibodies in sow serum correlates with the ability of piglets'maternal antibodies to resist PEDV infection.Therefore,the a-bility of maternal antibodies against PEDV in piglets can be evaluated by detecting PEDV S1 IgG antibodies in the serum of sows.In 10 PEDV-infected farms,the neutralizing antibodies to PEDV in the sera of sows after immunization were generally high,and the S1 IgG antibodies were also high,and their S/P values were higher than 3.5 in 66.9％of the farms(347/519),and the highest anti-body levels were found in the four farms in which PED did not occur,whereas the neutralizing an-tibodies in the immunized sows in the five PEDV-uninfected farms were generally low,and their S1 IgG antibodies were also low,and only 8.1％(13/161)having S/P values higher than 3.5.The re-sults suggest that most sows in PEDV-infected farms can provide good immunoprotection to pig-lets after immunization,while pigs in PEDV-uninfected farms need further immunization if they need to achieve a higher level of immunoprotection.The present study provides a substantial clini-cal basis for the use of PEDV S1 IgG antibody levels to assess the effectiveness of PEDV antibody protection in swine herds.

Objective:To evaluate the effect of goal-directed fluid therapy (GDFT) on postoperative acute kidney injury (AKI) in elderly patients undergoing long-time abdominal surgery.Methods:The medical records from elderly patients of both sexes, aged ≥ 65 yr, with a duration of operation ≥ 8 h and American Society of Anesthesiologists Physical Status classification Ⅱ or Ⅲ, undergoing elective first abdominal surgery for gastrointestinal tumors at the Shanxi Provincial People′s Hospital from October 1, 2016 to June 30, 2022, were collected from the electronic medical record database. Patients were divided into conventional fluid therapy group (group C) and GDFT group (group G) according to whether GDFT was employed during operation. In group C, blood pressure was maintained ≥90/60 mmHg or mean arterial pressure≥65 mmHg, and urine output more than 30 ml/h. In group G, the stroke volume variation was maintained ≤13%, and cardiac index ≥2.5 L·min -1·m -2. The patient general characteristics, requirement for fluid, urine output, blood loss, requirement for vasoactive agents and abdominal hyperthermic perfusion, and operation time were recorded during operation. The development of AKI within 72 h after operation and development of other complications (pneumonia, anastomotic leakage, surgical site infection, septic shock, arrhythmia) after operation were recorded. The length of hospital stay and 30-day mortality after operation were recorded. Results:A total of 125 patients were included in this study, with 41 patients in group C and 84 patients in group G. Postoperative AKI occurred in 19 patients, with an incidence of 15.2%. Compared with group C, the requirement for colloid, total volume of fluid infused and urine volume were significantly decreased during operation, the requirement for vasoactive agents was increased during operation ( P<0.05), the risk of postoperative AKI was reduced ( OR=0.23, P<0.05), and no significant change was found in the incidence of other postoperative complications, 30-day mortality, and length of hospital stay in group G ( P>0.05). Conclusions:GDFT can reduce the risk of AKI in the elderly patients undergoing long-time abdominal surgery.

It may improve psychiatric symptoms in female patients with schizophrenia.

OBJECTIVE To provide reference and suggestions for dynamic adjustment of classification management lists for clinical use of antibiotics and the promotion of rational use of antibiotics. METHODS The latest version of provincial classification management lists for clinical use of antibiotics were aggregated into the “national list”， which was compared with 2021 WHO AWaRe classification list of antibiotics （hereinafter referred as to “AWaRe classification list”） to make a descriptive statistical analysis about the number of different classes of antibiotics in the two lists and their differences. RESULTS Based on the different classification principles， 262 kinds of antibiotic preparations in the national list were classified into non-restricted （84）， restricted （83） and highly-restricted classes （95）， and 258 kinds in the AWaRe classification list were classified into access （87）， watch （142） and reserve classes （29）； 182 kinds of antibiotic preparations were both included in the two lists. In the national list， among the non-restricted antibiotic preparations， 36 kinds belonged to access class， 30 belonged to watch class and 1 belonged to reserve class； among restricted antibiotic preparations， 7 belonged to access class， 46 kinds belonged to watch class and 3 belonged to reserve class； among highly-restricted antibiotic 82805019。E-mail：yyy211anne@163.com preparations， 9 belonged to access class， 35 belonged to watch class and 15 kinds belonged to reserve class. Among them， 91 kinds of antibiotic preparations were not recommended by WHO （20 kinds） or not included in the AWaRe classification list （71 kinds）. CONCLUSIONS The classification methods of two lists are different in classification principles and grading of some similar drugs. The classification management list of antibiotics is one of the key points of antibiotics management， more research is needed in the future to provide sufficient evidence for optimizing antibiotics classification management.
