Objective To evaluate the association between self-reported neighborhood walkability environments and mortality in China.Methods The Prospective Urban Rural Epidemiology study in China(PURE-China)recruited 47 931 participants aged 35-70 from 12 provinces in China between 2005 and 2009.Neighborhood environmental indicators were collected using the Neighborhood Environment Walkability Scale(NEWS)questionnaire,with higher scores indicating better walkable environments.The primary outcomes were all-cause mortality and cardiovascular mortality,using Cox fragile model to evaluate the association between community walkability and outcomes,as well as exploring mediating pathways.Results Of 35 490 participants included in this study,60%were female,with a mean(SD)age of 51.5(9.6)years.The median follow-up was 11.7 years.This study found an association between higher community walkability score and reduced risk of all-cause mortality,with the total score(HR=0.85;95%CI,0.80-0.89),land-use mix(HR=0.84;95%CI,0.79-0.88),and crime safety(HR=0.84;95%CI,0.80-0.89)showing the most significant associations.NEWS can affect long-term adverse outcomes through lifestyle.Conclusions In the Chinese population,favorable community walkability is associated with lower all-cause mortality risk,which may support policymakers to take actions to mitigate the adverse effects of poor community en-vironments on health.

Objective To investigate the clinical efficacy of Xiaoluo Granules combined with an-tituberculosis drugs in the treatment of patients with cervical lymph node tuberculosis.Methods A retrospective analysis was conducted on the clinical data of 118 patients with cervical lymph node tu-berculosis who were treated in our hospital from January 2021 to January 2023.The patients were di-vided into control group(57 patients receiving conventional antituberculosis drug treatment)and ob-servation group(61 patients receiving Xiaoluo Granules combined with antituberculosis drug treat-ment)based on their treatment methods.The efficacy,traditional Chinese medicine(TCM)symptom scores,peripheral blood T-cell subsets,and type 1/type 2 helper T cell(Th1/Th2)-related cytokine levels,including tumor necrosis factor-α(TNF-α),interleukin-6(IL-6),interleukin-10(IL-10),and interferon-γ(IFN-γ),were compared between the two groups.Results After 6 months of treat-ment,the total effective rate in the observation group was higher than that in the control group(P＜0.05).After 6 months of treatment,the scores for pain,low fever,fatigue,anorexia,and night sweats decreased in both groups,and the scores for these symptoms in the observation group were lower than those in the control group(P＜0.05).After 6 months of treatment,CD3+,CD4+,and CD4+/CD8+increased,while CD8+decreased in both groups.Additionally,CD3+,CD4+,and CD4+/CD8+were higher,while CD8+was lower in the observation group than those in the control group(P＜0.05).After 6 months of treatment,TNF-α,IL-6,and IFN-γ levels decreased,while IL-10 levels increased in both groups.Furthermore,TNF-α,IL-6,and IFN-γ levels were lower in the observa-tion group than in the control group,while IL-10 levels were higher(P＜0.05).Conclusion Xia-oluo Granules combined with antituberculosis drugs can significantly improve the efficacy in the treatment of cervical lymph node tuberculosis and enhance immune function by upregulating CD3+,CD4+,CD4+/CD8+,and IL-10 levels and downregulating CD8+,TNF-α,IL-6,and IFN-γ levels.

Objective To evaluate the safety and efficacy of interventional embolization of middle meningeal artery(MMA)for the treatment of chronic subdural hematoma(CSDH).Methods The clinical data of 14 patients with CSDH(17 lesions in total),who were treated with simple embolization of MMA at the Yijishan Hospital of Wannan Medical College of China between July 2021 and July 2022,were retrospective analyzed.After superselective catheterization of MMA using a microcatheter was accomplished,Onyx-18 glue,a liquid embolization agent,was used to embolize the main trunk and the branches of MMA.Imaging follow-up was adopted at 30 days and 90 days after discharge from hospital to evaluate the absorption of hematoma,and the improvement of clinical symptoms was defined as the modified Rankin Scale score(mRS)being decreased≥1 point from the baseline value.Results Successful embolization of MMA was accomplished for all the 17 lesions in the 14 patients,and no procedure-related complications occurred.During the follow-up period,the clinical symptoms and signs were remarkably improved in all patients.The postoperative 90-day hematoma volume was reduced by more than 90%in 11 patients and by more than 40%in one patient,and in 2 patients the postoperative 30-day hematoma volume was reduced by more than 30%.Complete absorption of hematoma was seen in 11 patients,and partial absorption of hematoma was observed in 3 patients.Conclusion For the treatment of newly-developed or recurrent CSDH,interventional embolization of MMA is clinically safe and effective.(J Intervent Radiol,2024,32:12-16)

Objective To establish the methods of galvanic vestibular stimulation-vestibular evoked myogenic potentials(GVS-VEMPs)in healthy children and to obtain the normal value of GVS-cVEMP and GVS-oVEMP in these children in China.Methods Twenty(3～14 years)healthy children and 24 healthy adults(18～30 years)were enrolled for conventional examinations of GVS-cVEMP and GVS-oVEMP.Using the galvanic stimulation in-tensity under 3 mA/1 ms for children and 5 mA/1 ms for adults.The characteristics of elicitation and parameter re-sults of GVS-cVEMP and GVS-oVEMP in children and adults,as well as the pain scores and the elicitation of differ-ent stimulus intensities in the two age groups were recorded.Results The elicitation of GVS-cVEMP and GVS-oVEMP were both 100.0％in children and adult groups.The p1 latency,n1 latency and p1-n1 interval latency of GVS-cVEMP were 10.46±1.84 ms,16.98±2.12 ms and 6.52±1.42 ms respectively in children group,the n1 la-tency and p1-n1 interval latency were significantly shorter than the adult group(P＜0.05).The n1 latency,p1 la-tency and p1-n1 interval latency of GVS-oVEMP were 8.87±1.40 ms,12.25±1.80 ms and 3.39±1.07 ms re-spectively in children group with no significant difference between the two groups.The thresholds of GVS-cVEMP and GVS-oVEMP in children group were significantly lower than adult group(P＜0.01),but no differences were found in adult group regarding on the amplitude and interaural amplitude asymmetry ratio.In addition,with the in-crease of the intensity of galvanic stimulation,the correlation between pain scores and the elicitation rates of GVS-cVEMP and GVS-oVEMP also increased.Conclusion Using appropriate stimulus intensity and recording methods,GVS-cVEMP and GVS-oVEMP could be successfully assessed and detected in healthy children over 3 years old and adolescents.The latency of GVS-cVEMP in children is slightly shorter than that in adults,therefore we recommend selecting the matched age group for assessment in the children group.

As a collective noun of incense and medicine, fragrant medicine has long been integrated into Chinese culture. It is not only a symbol of the cultural exchange between China and foreign countries in the middle ancient times, but also plays a very important role in medicine and other fields. Among them, Borneol can not only be used for medicinal purposes, but also for incense and fumigation, as well as food, tea, wine and other applications. This paper intends to sort out the medicinal properties, effects and other applications of Borneol recorded in ancient books of traditional Chinese herbs in the past dynasties, focusing on summarizing its medicinal properties, meridians, effects, compatibility and application characteristics. In addition, modern pharmacological action was included as a supplement, in order to provide reference for the clinical use of Borneol in medicinal aspects.

AIM: To investigate the role and possible mechanism of gastrodin combined with dexamethasone in myocardial cell injury induced by oxygen-glucose deprivation. METHODS: Oxygen-glucose deprivation (OGD) model was established. The cells were divided into 5 groups: normal control group, OGD group, DEX group, GAS group and DEX+GAS group. The activity of myocardial cells was detected by CCK-8 test in each group. The activity of LDH was detected by colorimetry in each group. The apoptosis of myocardial cells was detected by TUNEL method in each group. The ELISA assay was used to detect the inflammatory factors in culture medium of myocardial cells in each group. Western blot was used to detect the expression of Notch1, Bax, Bcl-2 and Beclin1 in myocardial cells in each group.RESULTS: The results showed that GAS combined with DEX could significantly increase the activity of myocardial cells and decrease the apoptosis, reduce production of TNF-α, IL-6, IL-1β and promote production of IL-10, decrease the release of LDH significantly of myocardial cells induced by OGD. The results of Western blot showed that GAS combined with DEX increased the expression of Notch1, Bcl-2 and autophagy-related gene Beclin1, but decreased the expression of Bax of myocardial cells induced by OGD. CONCLUSION: The combination of GAS and DEX may promote autophagy and increase cell activity, inhibit apoptosis and inflammatory reaction by activating Notch signaling pathway, thereby reducing OGD-induced myocardial cells damage.

Objective:To analyze the correlation between indocyanine green retention rate at 15 minutes (ICG-R15) and modified Scheuer score in liver tissues of patients with hepatitis B e antigen-positive/negative chronic hepatitis B (CHB), and further explore the indocyanine green clearance test (ICGCT) applied value in judging the progress of CHB-related liver disease.Methods:407 HBeAg (+) / HBeAg (-) CHB inpatients with normal or slightly elevated serum alanine aminotransferase (ALT) [< 2 times the upper limit of normal (ULN)] and modified Scheuer score were collected, and divided into mild liver disease group (M group, 131 cases, modified Scheuer score < G2S2) and progressive liver disease group (A group, 276 cases, modified Scheuer score≥G2 and / or S2). Furthermore, the groups were sub-divided into HBeAg (+) - M group, HBeAg (-) - M group, HBeAg (+) - A group and HBeAg (-) - A group. The correlation between ICG-R15 and modified Scheuer score was analyzed retrospectively. The data were analyzed by SPSS 24.0 software.Results:Basic clinical characteristics: Among the 407 CHB cases with normal or mildly elevated serum ALT, 171 were HBeAg(+) CHB and 236 were HBeAg(-) CHB. The baseline mean serum HBV DNA was higher in HBeAg(+) CHB patients [(6.06 ± 1.95) log10IU/ml] than HBeAg(-) CHB patients [(3.60±1.37)log10IU/ml ( P = 0.000)]. Included patients ICG-R15 detection characteristics: (1) The baseline mean value of ICG-R15 was not statistically significant between the two groups of HBeAg(+) CHB and HBeAg(-) CHB, and was basically within the normal range (< 10%); (2) Comparison of ICG-R15 baseline mean value among the subgroups showed that the patients in the HBeAg(+)-A group/HBeAg(-)-A group were higher than the HBeAg(+)-M group/HBeAg(-)-M group patients, and the difference was statistically significant ( P = 0.013/ P = 0.000). Included patients’ correlation analysis between ICG-R15 and modified Scheuer score: (1) ICG-R15 and modified Scheuer score had shown weak positive correlation with inflammatory activity grade (g) in HBeAg (+) / HBeAg (-) CHB ( r = 0.237, P = 0.002); r = 0.244, P = 0.000); (2) There was a weak positive correlation between ICG-R15 and fibrosis stage (s) in HBeAg (+) / HBeAg (-) CHB ( r = 0. 254, P = 0; r = 0.225, P = 0.001). Included patients ICG-R15 predictive value for the severity of liver histological progression: when the cut-off value of ICG-R15 was 5.1%, the area under the receiver operating characteristic curve from M group to A group was 0.601 ( P = 0.001) for predicting HBeAg (+) / HBeAg (-) CHB patients. Conclusion:ICG-R15 is positively correlated with the modified Scheuer score of liver tissue in HBeAg (+)/HBeAg (-) CHB patients with normal or slightly elevated ALT. In addition, when the cut-off value of ICG-R15 was 10%, it could not accurately reflect the effective hepatocyte reserve function of HBeAg (+) / HBeAg (-) CHB patients with normal or slightly elevated ALT. Importantly, when the cut-off value of ICG-R15 is 4.0% ~ 5.0%, it may have predictive value for liver disease progression to modified Scheuer score ≥ G2 and / or ≥S2 in HBeAg (+) / HBeAg (-) CHB patients with normal or slightly elevated ALT.

HuR (human antigen R), an mRNA-binding protein responsible for poor prognosis in nearly all kinds of malignancies, is a potential anti-tumor target for drug development. While screening HuR inhibitors with a fluorescence polarization (FP) based high-throughput screening (HTS) system, the clinically used drug eltrombopag was identified. Activity of eltrombopag on molecular level was verified with FP, electrophoretic mobility shift assay (EMSA), simulation docking and surface plasmon resonance (SPR). Further, we showed that eltrombopag inhibited cell proliferation of multiple cancer cell lines and macrophages, and the anti-tumor activity was also demonstrated in a 4T1 tumor-bearing mouse model. The data showed that eltrombopag was efficient in reducing microvessels in tumor tissues. We then confirmed the HuR-dependent anti-angiogenesis effect of eltrombopag in 4T1 cells and RAW264.7 macrophages with qRT-PCR, HuR-overexpression and HuR-silencing assays, RNA stability assays, RNA immunoprecipitation and luciferase assays. Finally, we analyzed the anti-angiogenesis effect of eltrombopag on human umbilical vein endothelial cells (HUVECs) mediated by macrophages with cell scratch assay and Matrigel angiogenesis assay. With these data, we revealed the HuR-dependent anti-angiogenesis effect of eltrombopag in breast tumor, suggesting that the existing drug eltrombopag may be used as an anti-cancer drug.

Objective:The aim of this study was to design and perform "Tap-hammer"system that can be used to elicit vestibular evoked myogenic potentials (VEMP) in normal adults and to report the preliminary results of this system.Methods:A triggered Tap-hammer was designed, made and connected with an electric recording system, to form as a system for Tap-VEMP recording. Twenty healthy adult volunteers (7 males and 13 females, aged 20 to 37 years, 40 ears in total) were recruited for air-conducted sound VEMP (ACS-VEMP) and Tap-VEMP examinations. Waveforms and parameters of both VEMPs were recorded and analyzed. SPSS 22.0 software was used for statistical analysis.Results:The response rates of ACS-, Tap-ocular VEMP (oVEMP) and ACS-, Tap-cervical VEMP (cVEMP) were both 100% (40/40). The mean±SD n1 latency, p1 latency, n1-p1 interval, amplitude, and asymmetry ratio (AR%) of Tap-oVEMP were (9.80±2.51)ms, (13.90±3.26)ms, (4.09±1.43)ms, (16.43±9.61)μV, (22.68±17.35)% respectively. The mean±SD p1 latency, n1 latency, p1-n1 interval, amplitude, and asymmetry ratio (AR%) of Tap-cVEMP were (13.26±2.07)ms, (21.84±2.89)ms, (8.58±2.10)ms, (457.65±274.94)μV, (20.42±13.46)% respectively. Both n1 latency and p1 latency of Tap-VEMPs were shorter than those in ACS-VEMPs ( P<0.05). No statistical difference could be found between the two stimulation methods in the parameters of n1-p1 interval, amplitude, and asymmetry ratio( P>0.05). Conclusion:The Tap-hammer system can elicit VEMP responses in healthy young people. This system can be used as an alternative stimulation method for bone conduction VEMP.

Objective: To introduce the method of galvanic vestibular stimulation-vestibular evoked myogenic potentials (GVS-VEMP) as well as to observe and analyze the parameters and elicited rate of GVS-cVEMP and GVS-oVEMP in healthy young people in China. Methods: Twenty six normal young subjects were recruited for conventional examinations of GVS-VEMP. The subjects were 21-37 years old, average age was (25.8±3.7) years old, including 13 males and 13 females. The galvanic stimulation intensity of 3 mA/1 ms was used to evoke cVEMP and oVEMP on the sternocleidomastoid and inferior extraocular muscles respectively, and the intensity of stimulus was decreased until the response disappeared, the threshold, latency, amplitude, interval phase and interaural amplitude ratio(IAR) were calculated. SPSS18.0 software was used for statistical analysis. Results: All subjects were elicited normal GVS-cVEMP and GVS-oVEMP under 3 mA/1 ms, the elicited rate was 100%. The threshold of GVS-cVEMP was (1.18±0.47) mA, p1 latency was (10.43±1.54) ms, n1 latency was (17.91±1.20) ms, the amplitude was (102.47±56.77) uV and IAR was (0.26±0.20). The threshold of GVS-oVEMP was (1.12±0.50) mA, n1 latency was (8.46±1.05) ms, p1 latency was (11.83±1.27) ms, the amplitude was (9.12±6.82) uV and IAR was (0.25±0.20). In terms of gender and lateral comparison, only the GVS-oVEMP amplitude was higher for male than for female, which had significant statistical difference (P<0.05), and there was no statistical difference in the other parameters between GVS-cVEMP and GVS-oVEMP. Conclusion GVS-cVEMP and GVS-oVEMP could be elicited in healthy youth population, and the parameters could provide reference for subsequent vestibular function evaluation.
