Objective: To explore the feasibility of remotely obtaining complex information on traditional Chinese medicine (TCM) pulse conditions through voice signals. Methods: We used multi-label pulse conditions as the entry point and modeled and analyzed TCM pulse diagnosis by combining voice analysis and machine learning. Audio features were extracted from voice recordings in the TCM pulse condition dataset. The obtained features were combined with information from tongue and facial diagnoses. A multi-label pulse condition voice classification DNN model was built using 10-fold cross-validation, and the modeling methods were validated using publicly available datasets. Results: The analysis showed that the proposed method achieved an accuracy of 92.59% on the public dataset. The accuracies of the three single-label pulse manifestation models in the test set were 94.27%, 96.35%, and 95.39%. The absolute accuracy of the multi-label model was 92.74%. Conclusion Voice data analysis may serve as a remote adjunct to the TCM diagnostic method for pulse condition assessment.

Objective To discuss the effect of multidisciplinary family empowerment mode in home care for patients after receiving percutaneous endoscopic gastrostomy(PEG).Methods A total of 86 patients,who received initial PEG at the Jilin Provincial Cancer Hospital of China from January 2021 to July 2023,were selected for this study.The patients were randomly divided into observation group.The patients of the control group received routine nursing guidance for gastrostomy,while the patients of the observation group received multidisciplinary family empowerment nursing mode.The self-care ability[using self-care ability scale of the elderly(SASE)score],health behavior ability[using self-rating scale of health behavior ability(SRAHP)score],incidence of complications,and healing time of complications were compared between the two groups.Results In the observation group the SASE[(129.48±5.48)points vs.(73.05±12.04)points]and the SRAHP[(80.14±1.00)points vs.(70.25±7.92)points]were significantly higher than those in the control group(all P＜0.05),the incidence of complications was lower than that in the control group,and the healing time of complications was shorter than that in the control group.Conclusion The implementation of multidisciplinary family empowerment nursing mode can improve the self-care ability and health behavior ability of patients after receiving PEG,reduce postoperative complications,as well as shorten the healing time of complications,therefore,this nursing mode is suitable for home patients after receiving PEG.

In neurons and myocytes, selective ion channels in the plasma membrane play a pivotal role in transducing chemical or sensory stimuli into electrical signals, underpinning neural and cardiac functionality. Recent advancements in biomedical research have increasingly spotlighted the interaction between ion channels and electromagnetic fields, especially terahertz (THz) radiation. This review synthesizes current findings on the impact of THz radiation, known for its deep penetration and non-ionizing properties, on ion channel kinetics and membrane fluid dynamics. It is organized into three parts: the biophysical effects of THz exposure on cells, the specific modulation of ion channels by THz radiation, and the potential pathophysiological consequences of THz exposure. Understanding the biophysical mechanisms underlying these effects could lead to new therapeutic strategies for diseases.

OBJECTIVE To explore the effects of pterostilbene （PTE） on wound healing in diabetic skin ulcer model rats and its mechanism. METHODS Ten SD rats were grouped into control group； after diabetic skin ulcer model of other rats was induced by giving high-fat and high-sugar diet+intraperitoneal injection of streptozotocin+cutting off the skin and subcutaneous tissue in the marked area of the back， model rats were randomly divided into model group， PTE low-dose group （40 mg/kg）， PTE high-dose group （80 mg/kg）， PTE high-dose+PP2 group （80 mg/kg PTE+2 mg/kg SRC inhibitor PP2）， with 10 rats in each group. On the second day after modeling， the rats in each drug group were intraperitoneally injected with corresponding drug solutions， while the rats in control group and model group were intraperitoneally injected with normal saline， once a day， for 14 consecutive days. The wound healing rate of rats in each group was measured on the 7th and 14th day of administration； the contents of interleukin-1β （IL-1β）， IL-6， tumor necrosis factor-α （TNF-α） and vascular endothelial growth factor （VEGF） in the serum of rats were detected； the pathological changes of wound granulation tissue were observed， and the expressions of SRC/mitogen-activated protein kinase kinase （MEK）/extracellular signal-regulated kinase （ERK） signaling pathway-related proteins in wound granulation tissue were detected. RESULTS Compared with control group， the wound healing rate， serum content of VEGF， the phosphorylation levels of SRC， MEK1/2 and ERK1/2 were decreased significantly （P＜0.05）， while serum contents of IL- 1β， IL-6 and TNF-α were increased significantly （P＜0.05）； there was obvious infiltration of inflammatory cells in the wound granulation tissue， and the number of new blood vessels decreased. Compared with model group， above indexes of PTE low-dose and high-dose groups were improved significantly （P＜0.05）， and the pathological injury of granulation tissue in wound was improved. PP2 significantly reversed the improvement effects of PTE on the above indexes （P＜0.05）. CONCLUSIONS PTE can promote the wound healing of diabetic skin ulcer model rats， the mechanism of which may be related to activating SRC/MEK/ERK signaling pathway.

Objective:To investigate the clinical effect and short-term and long-term effect of total hip replacement (THA) and hemiarthroplasty of hip (HA) in elderly patients with femoral neck fracture (FNF).Methods:59 elderly patients with FNF in South District of Guang′anmen Hospital, Chinese Academy of Traditional Chinese Medicine from March 2017 to January 2019 were retrospectively analyzed. The observation group ( n=29) was treated with THA; The control group ( n=30) was treated with HA. The operation related indexes, short-term and long-term clinical effect (average follow-up of 24.1 months), hip function improvement, pain and complications were compared between the two groups. Short term and long-term clinical effects: the short-term and long-term clinical effects of the two groups were observed by the Harris Hip Score (HHS) of the first month, the third month, the sixth month, the ninth month and the first year after operation. Results:Both THA and HA were effective on elderly FNF, but the effective rate of THA (96.6%) was significantly higher than that of HA (90.0%), with statistically significant difference ( P<0.05); in terms of operation related indicators, compared with the control group, the observation group had longer operation time [ (104.46±3.24)min vs (84.34±3.64)min], more amount of bleeding [(296.64±15.16)ml vs (281.44±12.16)ml], lower postoperative drainage volume [(101.24±4.15)ml vs (74.56±3.24)ml], while the functional recovery of the observation group was better than the control group by HHS ( P<0.05); the postoperative complications and HHS score of observation group were significantly lower than the control group ( P<0.05). Conclusions:THA has the advantages of low complication, fast functional recovery and better effect. The clinical decision should be based on the patient′s physical condition. THA should be used for elderly patients with good basic condition, good surgical tolerance and more daily activities. HA should be used for elderly patients with poor basic condition, low surgical tolerance and less daily activities.

Objective To investigate the medium- and long-term effects and safty of Pipeline embolization device ( PED) for the treatment of large and giant intracranial anterior circulation aneurysms. Methods From December 2014 to December 2016,the data of 36 consecutive patients with large and giant aneurysm ( 36 large and giant intracranial anterior circulation aneurysms ) treated with PED in Donglei Brain Doctor Group were analyzed retrospectively. The diameter of the aneurysms was 12 -33 mm, (mean16.6±4.5mm),andthenecksizewas4-10mm(mean6.1±1.5mm).Eightaneurysmswere located in the carotid cavernous sinus segment,22 in the ophthalmic artery segment,5 in the internal carotid artery posterior communicating segment, and 1 in the M1 segment of middle cerebral artery. Seven aneurysms were only treated by PED,28 aneurysms were treated by PED in combination with coil embolization,and 1 aneurysm was treated by double PEDs. The modified Rankin scale ( mRS) score was used to evaluate the prognosis of the patients. Results (1) The clinical prognosis of the patients was followed up by telephone and outpatient department for 6-33 months. Twenty-five patients were followed up by DSA,23 aneurysms (92%) were occluded totally (Raymond gradeⅠ) and 2 (8％) were occluded near totally ( Raymond grade Ⅱ) . ( 2 ) Seven patients were treated with PED alone. Four patients were cured totally after 6 months follow-up,1 was occluded subtotally,2 were not cured;6 were cured in the last follow-up (33 months),and the other aneurysm was gradually reduced;17 of 28 patients treated with PED in combination with coils received DSA follow-up. They were followed up for 6-8 months. All the aneurysms were totally occluded ( Raymond grade Ⅰ) . 1 aneurysm was treated by 2 PEDs, DSA revealed micro-aneurysm-like development at 8 months after procedure. The aneurysms were basically occluded after 15-month follow-up. (3) MRI confirmed after operation that 10 patients had asymptomatic scattered spotted ischemic foci,4 had cerebral parenchymal hemorrhage,1 of them died,1 recovered well after treatment (mRS 1),and the other 2 were asymptomatic cerebral hemorrhage. The occupying effect of 24 cases disappeared, 8 had obvious improvement,and 3 did not have any obvious change. Conclusions The occlusion rate of the treatment of large and giant intracranial aneurysms with PED was high. The results of medium-term follow-up showed that the occlusion rate of PED in combination with coils in the treatment of aneurysms was higher than that of PED alone. The long-term follow-up results showed that the occlusion rate of patients treated with PED alone (including one or more) was gradually increased with time. The safety of the surgery needs to be further confirmed by a large sample study.
