OBJECTIVE: To observe the effects of electroacupuncture (EA) on improving motor function and regulating microglial activation based on Notch receptor 1 (Notch1)/Hes family bHLH transcription factor 1 (Hes1) pathway in mice with Parkinson's disease (PD). METHODS: Thirty-six male C57BL/6 mice were randomly divided into a control group, a model group and an EA group, 12 mice in each group. PD model was established by intraperitoneal injection of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) for 7 consecutive days in the model group and the EA group. From the 1st day of modeling, EA was applied at "Baihui" (GV20) and bilateral "Shenshu" (BL23) in the EA group, with continuous wave, in frequency of 2 Hz and current of 2 mA, 15 min a time, once a day for 14 days continuously. The behavioral performance was evaluated by gait test, pole climbing test and hanging test, the number of positive cells of tyrosine hydroxylase (TH) and the co-expression positive cells of Notch1/ionized calcium binding adaptor molecule 1 (Iba-1) in the substantia nigra of midbrain was assessed by immunofluorescence, the protein expression of TH, α-synuclein (α-syn), Notch1, Hes1, Iba-1, inducible nitric oxide synthase (iNOS), Arginase-1 (ARG1), tumor necrosis factor-α (TNF-α), interleukin (IL)-1β, IL-6 and IL-10 was detected by Western blot, the mRNA expression of Notch1 and Hes1 was detected by real-time PCR. RESULTS: Compared with the control group, in the model group, the stride frequency was accelerated (P<0.001) and the stride length was shortened (P<0.001) for the four limbs, the pole climbing test time was prolonged (P<0.01) and the grip level was reduced (P<0.01); in the substantia nigra of midbrain, the number of positive cells of TH was decreased (P<0.001), the number of co-expression positive cells of Notch1/Iba-1 was increased (P<0.001), the protein expression of α-syn, Notch1, Hes1, Iba-1, iNOS, TNF-α, IL-1βand IL-6 was increased (P<0.01, P<0.05, P<0.001), the protein expression of TH, ARG1 and IL-10 was decreased (P<0.01, P<0.001), the mRNA expression of Notch1 and Hes1 was increased (P<0.01). Compared with the model group, in the EA group, the stride frequency was decelerated (P<0.001) and the stride length was increased (P<0.05, P<0.01, P<0.001) for the four limbs, the pole climbing test time was shortened (P<0.05) and the grip level was increased (P<0.05); in the substantia nigra of midbrain, the number of positive cells of TH was increased (P<0.01), the number of co-expression positive cells of Notch1/Iba-1 was decreased (P<0.001), the protein expression of α-syn, Notch1, Hes1, Iba-1, iNOS, TNF-α, IL-6 and IL-1β was decreased (P<0.05, P<0.01), the protein expression of TH, ARG1 and IL-10 was increased (P<0.05, P<0.001, P<0.01), the mRNA expression of Notch1 and Hes1 was decreased (P<0.05). CONCLUSION EA can improve the behavioral performance and protect the dopaminergic neurons in PD mice, its mechanism may relate to the inhibition of Notch1/Hes1-mediated neuroinflammation, thus inhibiting the microglial activation.

Objective To systematic evaluate the impact of applying the clinical nursing pathway(CNP)on epidural anesthetic analgesia natural delivery.Methods The randomized controlled trial(RCT)and quasi-experimental researches on the application of CNP in epidural anesthetic analgesia natural delivery were retrieved from PubMed,Cochrane Library,Embase,Web of Science,China Knowledge Network database,Wanfang database,VIP and the Chinese Biomedical Literature Database.The retrieval time limit was from January 1,2014,to July 31,2024 with no language limitation.The meta analysis on the included studies was performed by applying RevMan5.4.1.Results A total of 5 RCTs and 2 quasi-experimental studies were in-cluded,involving 979 parturients with deliveries.The meta analysis showed that compared with the conven-tional nursing,CNP could shorten the duration of the first stage of labor(MD=—1.06,95％CI:—1.95——0.17,P=0.02)and the duration of the second stage of labor(MD=—0.12,95％CI:—0.21——0.03,P=0.006);decreased the rate of perineal lateral incision(RR=0.73,95％CI:0.65-0.83,P＜0.001)and inci-dence rate of postpartum urinary retention(RR=0.35,95％CI:0.20-0.63,P＜0.001);and shortened the time to lactation initiation(SMD=—1.52,95％CI:—2.38——0.66,P＜0.001).There was no influence on reducing postpartum 24 h hemorrhage amount(SMD=—0.51,95％CI:—1.23-0.21,P=0.16).The study subjects were divided into the primipara women subgroup and unclassified parturients subgroup.Compared with the conventional nursing group,compared with the conventional nursing,CNP had no impact on the dura-tion of the first stage of labor(MD=—0.32,95％CI:—0.61-0.98,P=0.63)and the duration of the second stage of labor(MD=—0.11,95％CI:—0.25-0.04,P=0.15)in the primipara women subgroup.CNP could reduce the postpartum 24 h hemorrhage volume in the unclassified parturients subgroup(SMD=—1.47,95％CI:—1.72——1.21,P＜0.001).Conclusion Application of CNP in parturients labor analgesia could reduce the perineal lateral incision rate and incidence rate of postpartum urinary retention and shorten the time to lac-tation initiation.Due to the heterogeneity among studies,the impact of CNP on the labor duration and the bleeding amount within postpartum 24 h still requires more high-quality studies to be conducted in the future for verification.

Central nervous system vasculitis (CNSV) is a type of inflammatory disease involving the blood vessels of the brain, spinal cord and meninges, and its clinical diagnosis is quite challenging. The sensitivity and specificity of traditional imaging examinations are very low, while high-resolution vessel wall imaging (HRVWI) can clearly show vascular wall and perivascular lesions. CNSV on HRVWI may manifested as concentric thickening and enhancement of the vascular wall, and perivascular enhancement with or without vascular stenosis. HRVWI has high value in the diagnosis and differential diagnosis of CNSV and related diseases. This article reviews the HRVWI characteristics of CNSV and the differential diagnosis of related diseases.

AIM:To investigate the mechanism of reduced tear secretion in depression-related dry eye rats based on 5-HT/TRPV4/AQP5.METHODS:Healthy SD male rats were established with chronic unpredictable mild stress(CUMS)method to establish a depression-induced dry eye model(n=8), and the control group was blank rats(n=8). The ELISA method was used to compare the 5-hydroxytryptamine(5-HT)in serum and hippocampal tissue of the two groups, and the HE sections of lacrimal gland and AQP5 immunohistochemistry were observed. Western blot and RT-PCR were used to detect the expression of 5-HT3R, TRPV4 and AQP5 in the lacrimal gland tissue of the two groups of rats.RESULTS:The tear secretion in the depression-induced group was significantly reduced(P=0.001), the serum and hippocampal 5-HT levels were significantly reduced(all P<0.05), the expression of AQP5 antibody in the lacrimal gland immunohistochemistry was significantly lower than that in the control group(P<0.001), the expression of 5-HT3R, TRPV4 and AQP5 in the lacrimal gland was significantly reduced(all P<0.05), and no obvious inflammatory cells were found in the lacrimal gland tissue sections.CONCLUSION:Depression-related dry eye may occur through a non-inflammatory 5-HT/TRPV4/AQP5 mechanism.

OBJECTIVE To construct a prevention and control index system suitable for stomatology outpatient de-partment of general hospital,so as to provide a theoretical basis for risk assessment of stomatology outpatient de-partment,and to provide an evidence-based basis for precise prevention and control.METHODS Based on the methods of literature research,literature quality evaluation and brainstorming,a draft index of the prevention and control of the general hospital's oral outpatient department was constructed,and the index system for the preven-tion and control in the stomatology outpatient department of a general hospital was finally established through re-search group discussion,content analysis and expert consultation.The three-level indicators in the index system were incorporated into the risk points of risk assessment,the failure mode and effects analysis were applied to con-duct the risk assessment,and the intervention measures and rectification cycles were formulated and implemented in clinical practice for the risk points with risk priority number(RPN)greater than 125.Based on the established index system and risk points with RPN＞125,the hospital infection prevention and control checklist for stoma-tology outpatient was developed and regularly checked in the clinic.After the rectification was completed,the risk points were evaluated again,and the RPN values were compared before and after the risk control.RESULTS The recovery rate of expert consultation questionnaire was 100.00％,and the average expert authority coefficient was 0.84.The consistency ratio(CR)for the first-level indicators was 0.0499,and the consistency ratio(CR)of the second-level indicators was 0.0000-0.0790,which was less than 0.1,and the consistency was acceptable.Final-ly,a hospital infection prevention and control index system was established,comprising 5 first-level indicators,7 second-level indicators and 23 third-level indicators.The improved key control risk points were evaluated again,and the RPN values before and after comparing the risk control were reduced and＜125,indicating that the im-provement measures were effective.CONCLUSION The evaluation system of prevention and control for the stoma-tology outpatient department of a general hospital established in this study is reliable,scientific and practical,and the improvement measures of risk assessment before and after the control of risk points are effective,which pro-vides evidence-based basis for risk assessment and precise prevention and control in the stomatology outpatient de-partment of general hospitals.

Objective:This study aimed to evaluate the association between obstructive sleep apnea-hypopnea syndrome (OSAHS) and reflux esophagitis (RE).Methods:This cross-sectional study retrospectively analyzed 218 patients diagnosed with OSAHS by polysomnography (PSG) and who also had undergone gastroscopy at the First People′s Hospital of Yunnan Province from January 2021 to December 2021. The cohort comprised 91 males and 127 females, aged from 19 to 78 years (40.7±13.2). Clinical data, PSG parameters, and gastroscopy findings were collected. The prevalence of RE among OSAHS patients was calculated, potential risk factors for RE were evaluated. Differences in PSG parameters between patients with and without RE were analyzed. Statistical analyses were conducted using SPSS 26.0.Results:The prevalence of RE in OSAHS patients was 20.6% (45/218). Males had a significantly higher RE prevalence than females (31.9% vs. 12.6%, χ2=12.02, P<0.05). The difference remained significant after adjusting for confounding factors (34.9% vs. 11.1%, χ2=10.08, P<0.05). No significant variation in RE prevalence was observed across age groups. However, after adjusting for confounding factors, a significant difference was found between overweight and obese BMI groups (12.5% vs. 29.2%, χ2=4.04, P<0.05). When stratified by apnea-hypopnea index (AHI) severity, RE prevalence increased progressively in mild (7.1%), moderate (18.8%), and severe (30.1%) groups, with statistically significant differences ( χ2=11.45, P<0.05). Positive correlations were found between RE and male sex, AHI, longest apnea time (LAT), and time spent with oxygen saturation below 90% (TS90%) ( rs=0.24, 0.18, 0.17, 0.14, respectively, P<0.05). Regression analysis showed that identified male sex was the primary independent predictor of RE. Patients with RE exhibited higher AHI, TS90%, and LAT compared to those without RE ( P<0.05) .Conclusion:This single-center hospital-based study revealed a relatively high prevalence of reflux esophagitis (20.6%) among patients with OSAHS. Male sex was identified as the main independent factor associated with RE. Furthermore, RE prevalence increased with greater AHI, BMI, LAT and TS90%.

Objective:To construct the user personas of the patients who practice self-management home rehabilitation after lower limb bone transport by exploring their self-management experiences and needs in rehabilitation at home so as to provide targeted countermeasures for related medical staff.Methods:A purposive sampling method was employed to select the 21 patients who had undergone home rehabilitation after lower limb bone transport at Department of Orthopedic Trauma, Nanfang Hospital from September to December 2024. The cohort included 12 males and 9 females, with an age of (39.8±15.1) years. The phenomenological research method was used to conduct semi-structured interviews with this cohort. After the data from interviews were explored by the Colaizzi 7-step analysis to extract the factual labels, role dimension models were built, covering 3 dimensions: description, characteristics (basic, cognitive, behavioral, social support, and psychological adjustment characteristics) and needs.Results:All patients were interviewed. Four user personas were constructed, including self-awareness growth type (5 cases), emotional dependency-driven type (4 cases), risk-aversion procrastination type (7 cases), and management motivation-impaired type (5 cases). The patients of self-awareness growth type were 21 to 36 years old and received high school or university education, characterized by high self-efficacy, active measures to improve and maintain their state of rehabilitation, good management of negative emotions, and a low sense of stigma. The patients of emotional low-driven type were 42 to 74 years old and received their education in a primary school or junior high school, characterized by lack of independence, dependence on others for rehabilitation management, common management of negative emotions, low self-efficacy, and a strong sense of stigma. The patients of risk-aversion procrastination type were 33 to 56 years old and received their education in a junior or senior high school, characterized by a willingness to cooperate but insufficient motivation for rehabilitation management, an awareness of rehabilitation which was vulnerable to external factors, common management of negative emotions, low self-efficacy, and a strong sense of stigma. The patients of management motivation-impaired type were 51 to 61 years old, received primary school education or lower, characterized by insufficient knowledge and poor self-management behavior, constant failure to follow the prescribed rehabilitation exercises, poor management of negative emotions, low self-efficacy, and a low sense of stigma.Conclusion:The user personas we have constructed for the patients who practice self-management home rehabilitation after lower limb bone transport can help healthcare professionals with specific targeted interventions to enhance self-management efficacy to facilitate the rehabilitation process for the patients.

Objective To investigate the effect of total paeony glycoside(TPG)on cerebral ischemia-reperfusion injury(CI/RI)of rats.Methods The rats were randomly divided into sham surgery(sham)group,CI/RI model group(simple CI/RI group),positive control group(nimodipine group,5 mg/kg),low-dose TPG group(TPG-L group,27 mg/kg),a high-dose TPG group(TPG-H group,54 mg/kg)and a high-dose TPG+NOD-like receptor thermal protein domain associated protein 3(NLRP3)activator diethyl dithiocarbamate(DDC)group(TPG-H+DDC group,54 mg/kg TPG and 30 mg/kg DDC),with 18 rats in each,administered once a day for 7 consecutive days.After the administration,the neurological deficit score of the rats was evaluated.Nissl staining microscopy was applied to observe neuronal activity in brain tissue.2,3,5-triphenyltetrazolium chloride(TTC)staining microscopy was applied to detect the area of cerebral infarction in rats.The level of interleukin-1β and IL-18 in brain tissue was measured by ELISA method.Western blot was applied to detect the expression of purinergic receptor P2X ligand-gated ion channel 7(P2X7R)/NLRP3 signaling pathway related proteins and pyroptosis related proteins such as apoptosis associated speck like protein containing a CARD(ASC)and cysteine protease 1(caspase-1)proteins in brain tissue.Results Compared with the sham group,the neurological deficit score,infarct area,level of IL-1β and IL-18 in brain tissue and protein expression of P2X7R,NLRP3,ASC,and caspase-1 in brain tissue of rats in the simple CI/RI group were significantly increased(P<0.05),while the proportion of Nissl body positive cells in brain tissue was significantly reduced(P<0.05).The change in corresponding indicators of rats in the nimodipine group,TPG-L group,and TPG-H group was opposite to those in the simple CI/RI group(P<0.05).NLRP3 acti-vator DDC antagonized the inhibitory effect of TPG on cell pyroptosis in CI/RI rats.Conclusions TPG may inhibit brain injury in CI/RI rats by down-regulating the P2X7R/NLRP3 pathway.
