Cell is the most basic unit of life,and normal metabolism is the key to cell growth and development.Reactive oxygen species(ROS)are important regulators of cell function,and hypoxi-a-inducible factor-1 alpha(HIF-1α)is a ROS receptor,which can activate transient receptor poten-tial vanilloid(TRPV)channel.TRPV is a sensor for temperature,pain,and osmotic pressure.Changes in the environment can induce changes in the activity of TRPV channel,which regulates various physiological and pathological processes of cells through its downstream signaling path-ways.Low temperature plasma can regulate cellular TRPV channel activity through HIF-1α.This article mainly reviews the effect of HIF-1α on cell function through TRPV channel,which has ref-erence significance for future research on various diseases related to TRPV channel and their pre-vention and treatment,as well as provides a new idea for using low temperature plasma technology to treat diseases through regulating TRPV channel.

Objective To investigate the mechanism of Jisuishang Formula on cervical myelopathy based on Wnt/β-catenin signaling pathway.Methods Thirty-six adult male SD rats were randomly divided into sham operation group,model group,positive control group(TAK-715,50 mg/kg),Jisuishang Formula low(9.7 g/kg),medium(19.4 g/kg)and high(38.8 g/kg)dose groups,with 6 rats in each group for 4 weeks.The BBB score and inclined plate test were observed at 1,2 and 4 weeks after surgery.HE and Nissl staining were used to observe the histopathology and neuronal condition of the spinal cord.Immunofluorescence was used to detect the protein expres-sions of BDNF,β-catenin,Bax and Bcl-2.Western blot and qRT-PCR were used to detect the expression of Wnt/β-catenin signaling pathway-related proteins and mRNAs.Results Compared with the sham group,the BBB score and inclined plate test score were significantly decreased(P<0.05),the expressions of BDNF,β-catenin and Bcl-2 decreased(P<0.05),the expression of Bax increased(P<0.05),the expressions of β-catenin,LRP-6 and p-GSK-3βdecreased(P<0.05),and the expressions of Caspase-3 and Caspase-9 increased(P<0.05).Compared with the model group,the BBB score and inclined plate test score were significantly increased in the high-dose Jisuishang Formula group(P<0.05),the expressions of BDNF,β-catenin and Bcl-2 increased(P<0.05),the expression of Bax decreased(P<0.05),the expressions of β-catenin,LRP-6 and p-GSK-3βincreased(P<0.05),and the expressions of Caspase-3 and Caspase-9 decreased(P<0.05).Conclusion Jisuishang Formula prescription can inhibit neuronal apoptosis,improve spinal cord microenvironment,and promote neurological function recovery by activating the Wnt/β-catenin signaling pathway.

Objective:To observe and assess the clinical value of electrophysiology of ocular surface in the diagnosis and treatment of blepharospasm in Meige syndrome (MS).Methods:A single-center, cross-sectional study. A total of 413 patients diagnosed with MS and undergoing surgical treatment at the Henan Provincial Meige Syndrome Diagnosis and Treatment Center of the Henan Provincial Third People′s Hospital from May 2022 to December 2023 were included as the MS group. A total of 110 age- and gender-matched spouses of patients and community volunteers were selected as the control group. The bioelectricity detection program of the electrooculogram was used; the frequency bandwidth was set at 0.3 to 300.0 Hz. Surface electrodes were employed to record the surface electrophysiological manifestations of the corrugator supercilii muscle and the lower orbicularis oculi muscle, as well as the conditions and temporal characteristics of spasm waves. Based on the amplitude and waveform of the electrophysiology of ocular surface signals, it can be classified into 0-4 grades. The blepharospasm was divided into conditionally induced type, spastic type, reverse spastic type, and oro-ocular elicited type. All patients were treated with neural circuit occlusion, and the postoperative follow-up time was 4.1 (0.5-19.0) months. The distribution of different grades of electrophysiology of ocular surface in the MS and control group at baseline were observed, as well as within the MS group at the last follow-up visit. Additionally, the blepharospasm grades in the MS group were also assessed. The comparison of the distribution of the number of eyes with different grades of electrophysiology of ocular surface between groups was conducted using the Mann-Whitney U test. Results:At baseline, in the MS group, the number of cases with corrugator supercilii muscle amplitudes and morphologies graded from 0 to 4 were as follows: 15 (3.60%, 15/413) for grade 0, 95 (23.00%, 95/413) for grade 1, 142 (34.38%, 142/413) for grade 2, 127 (30.75%, 127/413) for grade 3, and 34 (8.24%, 34/413) for grade 4. In the control group, the corresponding numbers of individuals were 82 (74.54%, 82/110) for grade 0, 24 (21.82%, 24/110) for grade 1, 4 (3.64%, 4/110) for grade 2, 0 (0.00%, 0/110) for grade 3, and 0 (0.00%, 0/110) for grade 4. For the orbicularis oculi muscle, there were 35 cases (8.47%) in grade 0, 124 cases (30.03%) in grade 1, 150 cases (36.32%) in grade 2, 90 cases (21.79%) in grade 3, and 14 cases (3.39%) in grade 4 in the MS group. In the control group, there were 86 cases (78.18%) in grade 0, 24 cases (21.82%) in grade 1, and 0 cases in grades 2, 3, and 4. There were statistically significant differences in the distribution of the number of eyes with different electrophysiology of ocular surface grading of the corrugator supercilii muscle and the orbicularis oculi muscle between the MS and control group ( Z=-14.51, -13.86; P<0.001). Meanwhile, there were statistically significant differences in the distribution of the number of eyes with different electrophysiology of ocular surface grading of the corrugator supercilii muscle and the orbicularis oculi muscle between preoperation and at the last follow-up in the MS group ( Z=-16.52, -17.36; P<0.001). In the MS group, there were 61 (14.77%, 61/413), 306 (74.09%, 306/413), 27 (6.54%, 27/413) and 19 (4.60%, 19/413) cases of blepharospasm conditionally induced type, spasm type, reverse spasm type and oro-ocular elicited type, respectively. Conclusion:The electrophysiology of the ocular surface can objectively reflect the activity of periocular neuromuscular.

Sacroiliac complex injuries are commonly seen in high-energy pelvic fractures. The injuries make a big difference in treatment patterns due to the diverse injury types, posing considerable challenges in formulating optimal treatment strategies, and hence are persistent clinical difficulties in orthopedic trauma. The clinical management of sacroiliac complex injuries presents several key challenges such as a non-negligible rate of missed diagnoses in associated vascular and visceral injuries, absence of standardized protocols for surgical approaches and reduction-fixation strategies across different injury patterns, and ongoing controversies regarding surgical indications and optimal timing for patients combined with concomitant lumbosacral plexus injuries. Currently, no systematic clinical guidelines are available for the diagnosis and treatment of sacroiliac complex injuries both domestically and internationally. To this end, the Pelvic and Acetabular Surgery Group, Orthopedic Branch, China International Exchange and Promotive Association for Medical and Health Care and Orthopedic Physician Branch, Chinese Medical Doctor Association organized a panel of domestic experts in the field to develop the Clinical guideline for the diagnosis and treatment of sacroiliac complex injuries ( version 2025), based on evidence-based medicine and adhering to the principles of scientific rigor, clinical applicability, and innovation. These guidelines provided 11 recommendations covering diagnosis, therapeutic principles and techniques, management protocols for lumbosacral plexus injuries, outcome evaluation, and postoperative rehabilitation pathways, etc., aiming to standardize the clinical management of sacroiliac complex injuries.

Objective To analyze the timeline of occupational disease online reporting and reviewing in Guangdong Province from 2014 to 2022. Methods Data and review information from the Occupational Diseases and Hazards Monitoring Information System under China Disease Prevention and Control Information System were collected to analyze the reporting timeline, review status, and timeline of review of "Occupational Disease Report Cards" for the years 2014 to 2022 in enterprises located in Guangdong Province. Results A total of 9 929 occupational disease report cards were recorded in Guangdong Province from 2014 to 2022, and the timely reporting rate of occupational diseases was 84.10%, with an overall upward trend. There was a statistically significant difference in the reporting time among different years (P<0.05), and the reporting time showed a downward trend. In 2022, the timely reporting rate of all cities reached over 80.00%. The final review rate of occupational disease report cards was 85.02%, and the review rate and timely review rate at the county level showed an increasing trend. The occupational disease report card audit timeliness rate from high to low was provincial, district county and city level (61.26% vs 43.87% vs 36.72%, all P<0.05). Conclusion The timeline of occupational disease reporting in Guangdong Province is relatively high, and the review at all levels is generally good. However, further improvement is needed for timely review at the municipal and county levels.

Objective To analyze the epidemiological characteristics of newly diagnosed occupational pneumoconiosis (hereinafter referred to as "pneumoconiosis") in Guangdong Province from 2011 to 2020. Methods Clinical data of newly diagnosed pneumoconiosis in Guangdong Province from 2011 to 2020 was collected from the “Health Hazards Monitoring Information System” under “China Disease Prevention and Control Information System”. The distribution of the cases was analyzed retrospectively. Results A total of 2 731 cases of newly diagnosed pneumoconiosis were reported from 2011 to 2020 in Guangdong Province, with cases at stages Ⅰ,Ⅱ, and Ⅲ accounting for 61.6%, 23.8%, and 14.6%, respectively. Except for talc pneumoconiosis, 12 other types of pneumoconiosis were reported. The top three incidence of diseases were silicosis, other pneumoconiosis, and welder's pneumoconiosis, accounting for 58.8%, 22.0% and 11.0%, respectively. Males accounted for 97.5%, and females 2.5%. The median age of onset was 47 years old. The median dust exposure duration was 9.8 years, with 19.4% of cases having a dust exposure duration less than 5.0 years. And 80.7% of the cases were distributed in the Pearl River Delta region. The industries with the new cases were mainly the manufacturing (accounting for 69.4%), and 34.8% of cases were found in private limited liability companies. Cases in medium- and small-sized enterprises accounted for 35.7% and 34.3% respectively. Conclusion Silicosis, other pneumoconiosis, and welder's pneumoconiosis are predominant in Guangdong Province. The prevention and control of pneumoconiosis should focus on small- and medium-sized private enterprises in the concentrated manufacturing industry in the Pearl River Delta region.
