Objective: To analyze epidemiological trends and changing characteristics of syphilis among students in Yunnan Province from 2005 to 2023, so as to provide evidence for the comprehensive prevention and control of syphilis in schools. Methods: The case data of syphilis among students in Yunnan Province from 2005 to 2023 were obtained from the China Information System for Disease Control and Prevention. The Joinpoint regression model was used to conduct a time trend analysis of the reported incidence rate of syphilis. Results: From 2005 to 2023, a cumulative total of 3 191 cases of syphilis were reported in schools in Yunnan Province(1 248 male cases and 1 943 female cases). The reported incidence rate rose continuously from 0.17/100 000 in 2005 to 8.26/100 000 in 2023, with an average annual percent change (AAPC) of 24.89%( Z =13.18, P <0.01). The reported incidence rate was higher in female students than in male students ( χ 2=229.48, P <0.05). The incidence rates in the primary school, junior high school, senior high school and higher education were 0.21/100 000, 2.42/100 000, 4.45/100 000 and 6.29/100 000 respectively, and the difference was statistically significant (χ 2=3 432.84, P <0.05). The average annual growth rate was the highest in the junior high school stage(AAPC= 30.68% , Z =7.57, P <0.05),followed by the senior high school stage (AAPC=24.28%, Z = 5.70 , P <0.05).The reported incidence rate of primary and secondary syphilis increased from 0.12/100 000 in 2005 to 2.06/ 100 000 in 2023, with an AAPC of 16.86% ( Z = 4.57, P <0.05). Conclusions The overall reported incidence rate of syphilis among students in schools in Yunnan Province shows a sustained upward trend, with the most rapid annual increase observed in junior high schools. Schools should prioritize syphilis education and expand awareness campaigns to curb transmission.

OBJECTIVES: To explore the effects of cannabidiol on endoplasmic reticulum stress and neuronal apoptosis in rats with multiple concussions (MCC). METHODS: SD rats were randomized into sham group, MCC group, 1% tween20 (TW) treatment group, and low-dose (10 mg/kg) and high-dose (40 mg/kg) cannabidiol treatment groups. In all but the sham group, MCC models were established using a metal pendulum percussion device, after which the rats received daily intraperitoneal injections of the corresponding agents for 2 weeks. The expressions of PERK, eIF2α, ATF4, CHOP, TRIB3, p-Akt and pro-caspase-3 in the brain tissue of the rats were detected with qRT-PCR, Western blotting and immunofluorescence staining. The core targets of cannabidiol in treatment of traumatic brain injury (TBI) were identified by network pharmacology analysis, and molecular docking was carried out to simulate the interaction of cannabidiol with the factors related to endoplasmic reticulum stress and apoptosis. RESULTS: Compared with the sham-operated rats, the rat models of MCC showed significantly increased mRNA expressions of PERK, eIF2α and CHOP and protein expressions of PERK, eIF2α, ATF4, CHOP, TRIB3, p-AKT and pro-caspase-3 in the cerebral cortex. CBD treatment, especially at the high dose, obviously increased the expression of p-Akt and lowered the expression levels of the other factors tested in the rat models. Network pharmacology analysis indicated interactions of the core targets of CBD with the factors related to endoplasmic reticulum stress and TBI, and molecular docking study showed a high binding energy of CBD with multiple factors pertaining to endoplasmic reticulum stress and apoptosis. CONCLUSIONS MCC induce endoplasmic reticulum stress and apoptosis in rat brain tissues, for which CBD, especially at a high dose, provides neuroprotective effects by inhibiting endoplasmic reticulum stress and cell apoptosis.

In the context of continuously deepening medical and health system reforms and comprehensively promoting the "Healthy China" strategy, Henan Provincial People's Hospital has established a regional collaborative and vertically integrated critical care service structure and network. This initiative aims to enhance information empowerment, strengthen regional collaboration, improve the insufficient primary medical services, and ensure timely and effective treatment for critically ill patients. By establishing a comprehensive dispatch service platform for regional collaborative critical care, building a "top-down" remote medical collaboration network, and forming a cross-regional specialty alliance for critical care, the hospital has improved the efficiency of medical services and enhanced regional capabilities for treating critically ill patients. Simultaneously, for critically serious patients and those with complex diseases at primary medical institutions, a one-stop consultation and referral service has been implemented. This service adopts a "three specialists" approach and a multidisciplinary consultation mechanism within the hospital, constructs a multi-dimensional critical care transfer mode integrating air, ground, and the internet, creates a regional collaborative rescue mode, and implements full-cycle treatment for critically serious patients. The comprehensive, flexible, and efficient service pathway for regional collaborative critical care established by this system ensures timely and safe treatment for critically ill patients, promotes the distribution of high-quality medical resources, and effectively addresses issues such as uneven distribution of high-quality medical resources and varying levels of critical care capabilities. It has facilitated the formation of a new tiered diagnosis and treatment order characterized by "first diagnosis at the primary level, two-way referral, separate treatment for acute and chronic diseases, and vertical integration". This approach has enhanced the diagnostic and comprehensive service capabilities of primary medical institutions. Currently, by strengthening information empowerment and sharing, creating a full-process critical care diagnosis and treatment model, providing medical assistance and cultivating primary-level critical care talent, and promoting appropriate technologies, the hospital has gradually overcome challenges such as barriers to information exchange and sharing between hospitals, overloaded critical care teams, high pressure on patient reception and transfer, and limited critical care capabilities at primary medical institutions. This article summarizes the construction and practical application of this regionally coordinated critical care system, aiming to provide a reference for the management of critical care treatment.

ObjectiveTo investigate the potential value of thyroid hormones in cerebrospinal fluid in predicting autism-like behaviors induced by hypothyroidism in pregnant rats. MethodsTwelve pregnant Wistar rats were randomly divided into a control group and a hypothyroidism group （hypothyroidism model group）. Offspring from both groups had serum and cerebrospinal fluid levels of thyroid-stimulating hormone （TSH）， total triiodothyronine （TT3）， total thyroxine （TT4）， free triiodothyronine （FT3）， and free thyroxine （FT4） levels in serum and cerebrospinal fluid. Ultrasonic vocalization tests were conducted on postnatal day 2 （P2）， day 7 （P7）， and day 14 （P14）， while behavioral tests using the three-box social interaction test were performed on day 21（P21）. ResultsCompared with the control group， free T4 （FT4） levels in the cerebrospinal fluid of the hypothyroidism group were significantly reduced during the developmental period （P0-P21； P2： P<0.05； P7： P<0.05； P14： P<0.01； P21： P<0.01）， with no statistical difference between the two groups only at P0 （P>0.05）. In the ultrasonic vocalization （USV） tests， the number and duration of USVs in offsprings from the hypothyroidism group were significantly reduced compared with those of the control group on P2， P7 and P14： for USV counts （P2： P<0.05； P7： P<0.001； P14： P<0.01）； for USV duration （P2： P<0.05； P7： P<0.001； P14： P<0.001）. In the three-box social tests， offsprings of the hypothyroidism group showed significantly reduced sniffing time with unfamiliar rats at P21 compared to the control group （all P<0.001）. The FT4 levels in cerebrospinal fluid had a significantly positive correlation with USV counts （P7： r=0.883， P<0.05； P14： r=0.902， P<0.05） and sniffing time with unfamiliar rats （r=0.814， P<0.01）. ConclusionMeasuring free T4 in cerebrospinal fluid can predict autism-like behaviors in offsprings of rats induced by hypothyroidism during pregnancy.

Objective To investigate the correlation between somatosensory evoked potentials(SEP)of upper limbs,and sensory and motor functions in stroke patients in different stages. Methods From June,2021 to October,2023,177 stroke patients in Shijiazhuang People's Hospital were diveded into acute stage group(within 14 days,n=25),early recovery group(14 days to one month,n=110)and middle to late recovery group(one to six months,n=42)according to the duration of the disease.General information of the patients was recorded;SEP examination was performed,and N20 lantency and amplitude were recorded.Monofilament touch and two-point discrimination sensation of the patient's hands were tested using the monofila-ment and two-point discrimination tools,respectively;and motor function was assessed with Fugl-Meyer Assess-ment-Upper Extremities(FMA-UE).The correlation between SEP,and the sensory and motor scores in each group was analyzed. Results There was no significant difference in the monofilament tactile and two-point discrimination scores among the three groups(P>0.05).SEP was not correlated with sensory and motor functions in the acute stage group(P>0.05);in the early recovery group,N20 latency was negatively correlated with monofilament tactile sensation(r=-0.267,P=0.005)and positively correlated with two-point discrimination sensation(r=0.220,P=0.021),and N20 amplitude was positively correlated with monofilament tactile sensation(r=0.328,P<0.001)and FMA-UE score(r=0.418,P<0.001),and negatively correlated with two-point discrimination(r=-0.405,P<0.001);in the middle to late recovery group,the N20 latency was negatively correlated with FMA-UE score(r=-0.313,P=0.044),and N20 amplitude was positively correlated with monofilament tactile sensation(r=0.598,P<0.001)and FMA-UE score(r=0.393,P=0.010),and negatively correlated with two-point discrimination(r=-0.591,P<0.001).Multiple linear regression analyses showed that the score of monofilament tactile sensa-tion was negatively correlated with N20 latency(β=-0.510,P=0.046),and the FMA-UE score was positively correlated with N20 amplitude(β=0.313,P=0.026)in the middle to late recovery group;in the early recovery group,the two-point discriminative sensation score was negatively correlated with N20 amplitude(β=-0.270,P=0.039). Conclusion The correlation between SEP and sensory and motor functions becomes more significant with the prolonga-tion of disease.

Objective:To investigate the effects of cannabidiol(CBD)on the NOD-like receptor protein 3(NLRP3)inflammasome in the brains of rats with multiple cerebral concussions(MCC).Methods:Rats were subjec-ted to the MCC model and divided into Sham,MCC,vehicle(MCC+TW),CBD-L(10 mg/kg),and CBD-H(40 mg/kg)groups.Immunofluorescence double staining was used to observe changes in NLRP3 and microglial cells in the brain,and Western Blot was performed to detect the expression changes of the NLRP3 inflammasome.Results:A sig-nificant increase in lectin-positive microglial cells of the cortex with enlarged cell bodies and elevated immunofluores-cence intensity of NLRP3 in the activated microglial cells was revealed by immunofluorescence double staining following MCC(P＜0.05).The immunofluorescence intensity of NLRP3 in the activated microglial cells was downregulated by the administration of CBD,with a more pronounced effect observed in the CBD-H group compared to the CBD-L group(P＜0.05).The expression of NLRP3,caspase-1,and apoptosis-associated speck-like protein(ASC)in the cortex,hippocampus,and basal ganglia of rats following MCC was significantly increased,as shown by Western Blot analysis(P＜0.05),and cortical areas are more elevated.The expression of these proteins in different brain regions was reduced by CBD-10 and CBD-40 intervention(P＜0.05).Conclusion:Cannabidiol can reduce the inflammatory response of multiple cerebral concussions rats through NLRP3 inflammasome and protect nerve tissue.

Objective:To explore the impact of scutellarin on the levels of phosphatidylinositol 3-kinase(P13K)and phosphorylated P13K(p-PI3K)in activated microglia.Methods:A rat cerebral ischemia model was made by middle cerebral artery occlusion(MCAO)method.SD rats were randomly divided into three groups:sham operation group(Sham),cerebral ischemia group(MCAO),and cerebral ischemia with scutellarin group(MCAO+S).A model of ischemia-hypoxia injury of BV2 microglia was established by glucose-oxygen deprivation(OGD)and randomly assigned as control group(Control),OGD group and OGD+scutellarin group(OGD+S).Changes in PI3K and p-PI3K expres-sion in microglia were assessed using double immunofluorescence staining and Western Blot.Results:Immunofluores-cence staining and Western Blot analyses revealed a significant increase in p-PI3K levels in activated microglia both in vivo and in vitro(P＜0.05).Furthermore,treatment with scutellarin led to a further elevation in p-PI3K(P＜0.05).However,there were no significant alterations observed in PI3 K expression among the groups(P＞0.05).Conclusion:Scutellarin may play a positive role in the treatment of cerebral ischemia by up-regulating the phosphorylation level of P13K in activated microglia.
