Osteoporosis is a common bone disease， whose incidence is still on the rise， posing great challenges to patients and society. This review mainly studies the pathogenesis of osteoporosis from the aspects of oxidative stress， inflammatory response， and glucolipotoxicity-induced injury and clarifies the efficacy and mechanism of some active ingredients of traditional Chinese medicine against osteoporosis through the integration of in vitro and in vivo experiments. The experimental results suggest that some active ingredients can improve bone resorption markers and maintain bone homeostasis by modulating inflammation， oxidative stress， etc. These active ingredients regulate osteoporosis through the receptor activator of nuclear transcription factor-κB （NF-κB） ligand （RANKL） pathway， osteoprotegerin （OPG） pathway， Wnt/β-catenin pathway， NF-κB pathway， mitogen-activated protein kinase （MAPK） pathway， adenosine monophosphate （AMP）-activated protein kinase （AMPK）/mammalian target of rapamycin （mTOR） pathway， and oxidative stress pathway. This review provides ideas for the progress of the prevention and treatment of osteoporosis with the active ingredients of traditional Chinese medicine， aiming to provide new potential lead compounds and reference for the development of innovative drugs and clinical therapy for the treatment of osteoporosis.

OBJECTIVE To systematically evaluate medication risk prediction models for hospitalized adult patients and provide references for their development and clinical application. METHODS Databases including PubMed， Embase， Web of Science， CNKI， Wanfang data， VIP and CBM were searched for studies on medication risk prediction models from their inception to May 2024. After screening the literature， extracting data， and evaluating the quality of the literature， descriptive analysis was performed on the results of the included studies. RESULTS A total of 13 studies were included， involving 12 models. Nine studies used Logistic regression algorithm for modeling， and the number of included predictive factors ranged from 3 to 11； the area under the receiver operating characteristic curve ranged from 0.65 to 0.865. The literature quality evaluation results showed that 10 studies had high risk of bias； 10 studies had high applicability risk. A total of 31 predictive factors were extracted， including 15 items of basic patient information， 3 test indicators， and 5 items of medication information， and 8 others. CONCLUSIONS The existing medication risk prediction models for hospitalized adult inpatients are mainly Logistic regression algorithm， with predictive factors mainly focusing on basic indicators such as demographics. The overall prediction performance of the models needs to be improved， and the overall risk of bias is relatively high.

This study aimed to comprehensively examine the association of gallstones, cholecystectomy, and cancer risk. Multivariable logistic regressions were performed to estimate the observational associations of gallstones and cholecystectomy with cancer risk, using data from a nationwide cohort involving 239 799 participants. General and gender-specific two-sample Mendelian randomization (MR) analysis was further conducted to assess the causalities of the observed associations. Observationally, a history of gallstones without cholecystectomy was associated with a high risk of stomach cancer (adjusted odds ratio (aOR)=2.54, 95% confidence interval (CI) 1.50-4.28), liver and bile duct cancer (aOR=2.46, 95% CI 1.17-5.16), kidney cancer (aOR=2.04, 95% CI 1.05-3.94), and bladder cancer (aOR=2.23, 95% CI 1.01-5.13) in the general population, as well as cervical cancer (aOR=1.69, 95% CI 1.12-2.56) in women. Moreover, cholecystectomy was associated with high odds of stomach cancer (aOR=2.41, 95% CI 1.29-4.49), colorectal cancer (aOR=1.83, 95% CI 1.18-2.85), and cancer of liver and bile duct (aOR=2.58, 95% CI 1.11-6.02). MR analysis only supported the causal effect of gallstones on stomach, liver and bile duct, kidney, and bladder cancer. This study added evidence to the causal effect of gallstones on stomach, liver and bile duct, kidney, and bladder cancer, highlighting the importance of cancer screening in individuals with gallstones.

Objective To understand the willingness to engage in the combine medical care with old-age care institutions of medical students in vocational colleges and analyze their influencing factors.Methods By convenient sampling method,1 266 medical students from 3 vocational colleges in Hunan Province were select-ed as the research objects,and their occupational cognition and occupational willingness were investigated and analyzed.Through objective sampling,20 medical students who were not willing to work in medical institu-tions were selected for semi-structured interviews.Results 62.1%of medical students intend to work in med-ical institutions after graduation;The results of multi-factor analysis showed that the experience of caring for the elderly,understanding of the nursing institution,participating in the volunteer service of the nursing insti-tution,and cognition score of the combination of medical care and nursing were the influencing factors of med-ical students'career intention(P＜0.05).The qualitative interview found that professional identity,job abili-ty,salary,social security and promotion were the main influencing factors.Conclusion Medical students in medical nursing institutions do not have strong willingness,so they should improve their professional cogni-tion of old-age service,enhance their professional identity and post competency,fully implement salary,social security and professional title promotion,attract more medical students to engage in the combined service in-dustry,and promote the combined development of medical care.

Objective To investigate the functional changes of oligodendrocytes in a mouse model of cognitive impairment induced by microwave radiation and the mechanism.Methods C57BL/6N male mice were exposed to S-band microwave at 2.856 GHz and 8 mW/cm2 for 15 min.The rectal temperature of mice was monitored by an optical fiber thermometer during microwave radiation.The changes of autonomous exploration behavior and learning and memory ability of mice on the 1st and 7th days after microwave radiation were detected via the open field test and novel object recognition test.Immunofluorescence was used to detect the expression and distribution of neuroglia-2 proteoglycan(NG2)and myelin basic protein(MBP)in the hippocampus of mice on the 1st and 7th days after radiation.Clemastine fumarate,a drug that promoted the maturation of oligodendrocyte precursor cells was administered by gavage,and the expression levels of brain-derived neurotrophic factor(BDNF)and fibroblast growth factor 2(FGF2)in hippocampal tissues were detected by radioimmunoassay at 1 and 7 days after radiation.The changes of myelin sheath structure an 1 and 7 days after radiation were observed by transmission electron microscopy.The effects of clemastine fumarate on learning and memory impairment induced by microwave exposure in mice were assessed via open field and new object recognition experiments.Results Under the experimental conditions,the rectal temperature in mice caused by microwave radiation increased by less than 1 ℃,which was within the thermal safety range of the body.The open field test showed that compared with the control group,the microwave radiation group didn't change significant in terms of movement speedon the 1st and 7th days,but the time spent exploring in the central area was significantly reducedon the 1st day after radiation(P＜0.05).In the novel object recognition test,the indexes of the mice on the 1st day were significantly reduced(P＜0.05),indicating that the anxiety like behavior and cognitive function of the mice were impaired after microwave radiation.Compared with the control group,the proportion of NG2+area in the hippocampus was significantly decreased(P＜0.05)in the microwave radiation group,while that of MBP+area hardly changed on the 1st day after microwave radiation(P＞0.05).The expression level of oligodendrocyte related BDNF in the hippocampus was significantly decreased(P＜0.05).The myelin of the corpus callosum was broken,and the myelin g ratio was significantly increased(P＜0.05),suggesting that micro wave radiation could reduce the number of oligodendrocyte precursors and damage the secretion and myelin function of oligodendrocyte.Compared with the radiation group,the expression levels of BNDF and FGF2 in the radiation combined with clemastine fumarate group were up-regulated,the myelin g ratio was significantly decreased on the 1st day after radiation(P＜0.05),and the novel object recognition index was significantly increased(P＜0.05).Conclusion Pulsed microwave radiation below the body's fever threshold can cause cognitive dysfunction and other brain damage in mice.The impaired secretion and myelin function of oligodendrocytes and the decreased self-repair ability are the important mechanisms of cognitive dysfunction induced by microwave radiation.

Objective:To compare the pregnancy outcomes of luteal phase and follicular phase progestin-primed ovarian stimulation protocol with clomiphene citrate supplementation(LPPOS+CC and FPPOS+CC)in young women with diminished ovarian reserve(DOR).Methods:A total of 483 women aged≤35 years with DOR,who underwent in vitro fertilization(IVF)/intracytoplasmic sperm injection(ICSI)/embryo transfer(ET)with controlled ovarian stimulation using LPPOS+CC(n=257)or FPPOS+CC(n=226)protocols during June 2018 and December 2021 at the First Affiliated Hospital of Wenzhou Medical University,were included in this retrospective study.The baseline characteristics,superovulation results,laboratory related indicators between the two groups,and the pregnancy outcomes of women who achieved at least one high-quality cleavage-stage embryo or good-morphology blastocyst were compared between the two groups.Results:No statistically significant differences were identified between the groups with respect to age,duration of infertility,proportion of secondary infertility,previous failed cycles,body mass index,anti-Müllerian hormone,antral follicle count,basal luteinizing hormone level,basal progesterone level,number of oocytes retrieved,oocyte maturation rate,high-quality cleavage-stage embryo cycle rate,the percentage of women with profound pituitary suppression,live birth rate and preterm birth rate(all P＞0.05).The LH levels on the day of trigger[4.0(2.7,5.3)vs.5.1(3.2,7.2)IU/L],the percentage of women with LH levels of＞10 IU/L on the trigger day(3.13%vs.10.67%),and the two pronucleus(2PN)rate of ICSI oocytes(72.16%vs.79.56%)were significantly lower in the LPPOS+CC group than those in the FPPOS+CC group(P＜0.05 or P＜0.01).The duration of stimulation[11(9,12)vs.9(8,11)d],the consumption of total gonadotropin[2213(1650,2700)vs.2000(1575,2325)IU],the progesterone levels on the day of trigger[1.3(0.8,2.9)vs.0.9(0.6,1.2)ng/mL],the clinical pregnancy rate[61.88%vs.46.84%],and implantation rate[42.20%vs.31.07%]in the LPPOS+CC group were significantly higher than those in the FPPOS+CC group(all P＜0.01).Conclusion:Compared to FPPOS+CC,the LPPOS+CC protocol appears to have better pregnancy outcomes for young women with DOR undergoing IVF/ICSI-ET.

OBJECTIVE To study the regulation effects and mechanism of liquiritin （LIQ） on immune function in gastric cancer-bearing mice based on the Janus kinase 2 （JAK2）/signal transducer and activator of transcription 3 （STAT3） pathway. METHODS Gastric cancer cells MFC were injected subcutaneously to establish gastric cancer-bearing model of mice. The model mice were divided into model group， LIQ low-dose group （LIQ-L group， 20 mg/kg）， LIQ high-dose group （LIQ-H group， 40 mg/kg）， and high-dose LIQ+JAK2 activator coumermycin A1 group （LIQ-H+coumermycin A1 group， 40 mg/kg LIQ+1 mg/kg coumermycin A1）， with 12 mice in each group. Another 12 mice without modeling were set as normal group. Mice in each group were given the corresponding drug or normal saline by intragastric administration/intraperitoneal injection， once a day， for consecutive 14 days. After the last administration， the volume and mass of gastric cancer tumor and organ index were measured. The percentages of CD4+ and CD8+T lymphocytes were detected in peripheral blood. The histopathological morphology of gastric cancer tumor tissues was observed， and the expression levels of JAK2/STAT3 signaling pathway-related proteins and interleukin-6 （IL-6） protein in gastric cancer tumor tissues were detected. RESULTS Compared with the normal group， the thymus index， spleen index， and the percentage of CD8 T lymphocyte in the peripheral blood of mice were obviouslyincreased in model group （P＜0.05）， while the percentage of CD4+T lymphocyte in the peripheral blood were decreased （P＜0.05）. Compared with model group， the above indexes in LIQ-L group and LIQ-H group were significantly reversed （P＜0.05）， while the volume and mass of gastric cancer tumor， the phosphorylation levels of JAK2 and STAT3 protein and the expression level of IL-6 protein were significantly decreased in tumor tissue （P＜0.05）， and the effect of LIQ was in a dose-dependent manner （P＜0.05）； the tumor cells showed varying degrees of loose arrangement， vacuolization， and uneven distribution. JAK2 activator coumermycin A1 weakened the improvement effect of LIQ on the immune function of gastric cancer-bearing mice and its inhibitory effect on gastric cancer tumors （P＜0.05）. CONCLUSIONS LIQ can improve the immune function of gastric cancer-bearing mice by inhibiting the activation of JAK2/STAT3 signaling pathway， thus playing an anti-tumor role.

Objective: To understand the status and related knowledge requirements of health emergency literacy among college students in Shaanxi Province, so as to provide the basis for improving college students health emergency literacy. Methods: A total of 2 723 students from 18 colleges and universities in Shaanxi Province were selected by multi stage random sampling and simple random sampling methods in November 2023, and the survey of health literacy in emergency and knowledge requirements of health emergency literacy was conducted. Statistical analysis was carried out by using χ 2 test, Wilcoxon rank sum test, Kruskal-Wallis H test and Logistic regression analysis. Results: About 28.98% of the surveyed college students had a high level of health emergency literacy, which varied by students whether being only one child, whether having left behind experience, with different personality types, whether being student cadres, and with different frequencies of community or social activities ( χ 2=9.15, 7.90, 32.73, 16.29 , 120.25, P <0.05). The equivalence scores of the four dimensions of health emergency literacy from high to low were poisoning and nuclear and radiation (0.84), medical rescue (0.83), infectious disease (0.82), and basic knowledge and behavior ( 0.77 ). Logistic regression analysis found that college students with left-behind experience were negatively correlated with health emergency literacy and its four dimensions ( OR =0.74, 0.72, 0.80, 0.80, 0.83), while personality type (rational type), community or social activity frequency were positively correlated with the cognitive levels of health emergency literacy and its four dimensions among college students ( OR =1.57, 1.50, 1.33, 1.27, 1.38)( P <0.05). There was a higher level of basic knowledge and behavioral cognition among only child college students ( OR =3.73), and female students had a higher level of health emergency literacy, as well as awareness of infectious disease outbreaks and medical rescue ( OR =1.21, 1.28, 1.21)( P <0.05). The radar map showed that the level of health emergency literacy was positive development radar map. About 67.68 % of the students had a high willingness to acquire health emergency literacy knowledge, and the demand for basic health emergency knowledge and behavioral knowledge was the highest (52.37%). Conclusions College students have insufficient health emergency literacy, but they have the highest demand for health emergency. Publicity and education should be strengthened for students with left behind experience, irrational type, and low frequency of community or social activities.

[Objective] To investigate the pathological characteristics of false-positive lesions of prostate cancer on ⁶⁸Ga-PSMA-11 PET/CT based on the pathology of whole mount specimens, in order to more accurately assess the degree of malignancy within the prostate tissue and avoid overdiagnosis and unnecessary treatment. [Methods] A total of 77 patients who underwent ⁶⁸Ga-PSMA-11 PET/CT before radical prostatectomy in Nanjing Drum Tower Hospital during Jan.2018 and Dec.2022 were retrospectively analyzed.The pathology of whole mount specimens was detected.Two nuclear physicians examined all imaging plates without knowing the pathological results.Two pathological physicians completed all pathological diagnosis without knowing the imaging results.The pathological characteristics of false-positive lesions were determined by matching ⁶⁸Ga-PSMA-11 PET/CT and pathological specimens.To analyze the pathological features of false-positive lesions, true-negative lesions were randomly delineated and defined.The pathological features of false-positive and true-negative lesions were analyzed and compared using Fisher exact test. [Results] After the imaging and pathological sections were matched, 21(16.3%) false-positive lesions were identified.The pathological characteristics of the 21 false-positive lesions were as follows: 16 (76.2%) simple atrophy with cyst formation, 3(14.3%) prostatic nodular hyperplasia, and 2(9.5%) inflammation.The pathological characteristics of 21 true-negative lesions were: 13(61.9%) normal glands, 5(23.8%) prostatic nodular hyperplasia and 3(14.3%) simple atrophy with cyst formation.Fisher exact test showed that the proportion of simple atrophy with cyst formation in the pathological features of false-positive lesions and true-negative lesions was statistically significant (76.2% vs.14.3%, P<0.001). [Conclusion] Simple atrophy with cyst formation may be a characteristic pathological type of the false-positive lesions of prostate cancer on ⁶⁸Ga-PSMA-11 PET/CT.
