ObjectiveThis study aims to investigate the therapeutic effects of Wenweishu granule （WWSG） on functional dyspepsia （FD） with spleen-stomach deficiency cold syndrome in rats by integrating network pharmacology， molecular docking， and animal experiments. MethodsActive components and corresponding targets of WWSG were collected from the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform （TCMSP） and the Bioinformatics Analysis Tool for Molecular Mechanism of Traditional Chinese Medicine （BATMAN-TCM）. Disease-related targets for FD with spleen-stomach deficiency cold syndrome were screened using GeneCards and the Integrative Pharmacology-based Research Platform of Traditional Chinese Medicine （TCMIP）. Core therapeutic targets were identified via Cytoscape and validated by molecular docking. A rat model of FD with spleen-stomach deficiency cold syndrome was established using vinegar gavage combined with tail-clamping. The rats were randomly divided into a model group， low-， medium-， and high-dose WWSG groups （2.0， 4.0， 8.0 g·kg^-1）， a domperidone group （3.0 mg·kg^-1）， a Fuzi Lizhong pillwan （0.8 g·kg^-1）， and a normal control group （n=10 per group）. Drugs were administered once daily by gavage for 14 consecutive days. After treatment， body weight， symptom scores， and gastrointestinal motility indices were recorded. Gastric and duodenal pathologies changes were observed via hematoxylin-eosin （HE） staining. Brain-gut peptides were measured in serum and tissue using enzyme-linked immunosorbent assay （ELISA）. Immunohistochemistry and Western blot were performed to assess stem cell factor （SCF） and receptor tyrosine kinase （c-Kit） protein expression in gastric tissues. ResultsA total of 305 drug targets， 1 140 disease targets， and 116 overlapping targets were identified. Cytoscape analysis revealed 104 core targets. Enrichment analysis indicated that the SCF/c-Kit signaling pathway was the key mechanism. Molecular docking confirmed a strong binding affinity between active components of WWSG and SCF/c-Kit proteins （binding energy<-5.1 kcal·mol^-1）. Compared with the normal group， model rats exhibited slower weight gain （P<0.05）， reduced gastric emptying and intestinal propulsion （P<0.01）， mild gastric mucosal shedding， duodenal inflammatory cell infiltration， decreased levels of gastrin （GAS）， 5-hydroxytryptamine （5-HT）， and vasoactive intestinal peptide （VIP） （P<0.05， P<0.01）， and elevated somatostatin （SS） expression （P<0.05， P<0.01）. WWSG treatment ameliorated weight gain， symptom scores， and low-grade inflammation in gastric/duodenal tissues. High-dose WWSG significantly improved gastric emptying and intestinal propulsion， upregulated GAS， 5-HT， and VIP， and downregulated SS expression in serum and tissues （P<0.05， P<0.01）. Immunohistochemistry and Western blot demonstrated that SCF and c-Kit protein expression was decreased in the model group （P<0.05， P<0.01）， which was reversed by WWSG intervention （P<0.05）. ConclusionWWSG exerts therapeutic effects on FD with spleen-stomach deficiency cold syndrome in rats， potentially by regulating the SCF/c-Kit signaling pathway to enhance gastrointestinal motility.

Objective: To analyze the changes in classroom lighting environment of schools in Suzhou and their impact on refractive progression among primary and secondary school students, so as to provide the basis for accurate provention and control of myopia. Methods: A baseline investigation was conducted in October 2022 by using a stratified cluster random sampling method to recruit primary and secondary school students from Suzhou. A follow up visit was performed in October 2023. A total of 12 302 students and 360 classrooms that participated in both surveys were included analysis. The visual acuity progression over one year and classroom lighting conditions were assessed. Group comparisons were performed by using the Wilcoxon or Kruskal-Wallis rank-sum, and Chi-square tests. Multivariate Logistic regression was employed to identify the major factors influencing refractive changes. Results: The compliance rate of average illuminance on classroom blackboard surface increased from 72.22% to 75.28%, while the compliance rate of average illuminance on desks decreased from 89.44% to 87.22%, the overall myopia rate among students rose from 59.63% to 66.99% from 2022 to 2023. The average annual progression of equivalent spherical power(SE) in the right eye of students was -0.25(-0.75,0.06)D. Significant statistical differences were observed in the annual mean changes across different school levels, regions, baseline refractive statuses, and classroom lighting environment change groups ( Z/H =316.59, -8.27, 38.80 , 51.01, all P <0.05). Multivariate Logistic regression analysis showed that pre myopia, low myopia, junior high school, senior high school, vocational high school, and improved classroom lighting environment were protective factors of reducing the risk of rapid progression in refractive error ( OR =0.58, 0.69, 0.81, 0.50, 0.28, 0.82, all P <0.05). Conversely, female students and rural students had higher risks of rapid myopia progression ( OR =1.09, 1.42, both P <0.05). Conclusions Over one year follow up, the complance rate of classroom lighting indicators in Suzhou remaines stable, while students refractive status shows a trend toward myopia. Improving classroom lighting environment can reduce the risk of rapid myopia progression.

Vitamin D(VD)is a fat-soluble vitamin closely related to bone health and calcium and phosphorus metabolism.VD deficiency in humans has become a global public health problem,especially in pregnant women as it affects maternal health and fetal growth,develo-pment,and susceptibility to many diseases.Recent studies have shown that adequate cord blood VD levels are associated with a reduced incidence of eczema in infants aged<1 year.With the increasing annual incidence of eczema in infants,its association with VD nutritional status has begun to receive attention.However,few epidemiological studies have investigated the association between VD levels during pregnancy and infantile eczema,and the results have been inconsistent.Therefore,this study reviews the association between VD nutri-tional status during pregnancy and infantile eczema,which may provide a theoretical basis for further exploring the role of VD nutritional status in the development of infantile eczema and taking targeted preventive and curative measures.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective Cervical disc herniation(CDH)is one of the common orthopaedic diseases.With the in-depth study of it and the development of cervical implants,the establishment of cervical fusion animal models has become an indispensable part.Notably however,studies of the establishment and evaluation of cervical fusion animal models in China are currently lacking.This study aimed to provide a suitable animal model and evaluation scheme for implants for cervical spine-related research.Methods Small-tailed Han sheep were chosen for anterior cervical discectomy fusion(ACDF)after modified surgery,and a polyetheretherketone(PEEK)interbody fusion cage(Cage)(control group),3D-printed Ti6Al4V Cage(group 1),and new method Ti6Al4V Cage(group 2)were implanted in different cervical segments(C2/3～C4/5)in each sheep,respectively.Hematology and histopathological analyses were carried out after surgery to evaluate recovery of sheep and the biosafety of the materials.Bone in-growth and bone fusion were assessed by X-ray,computed tomography(CT),Micro-CT and quantitative analysis,hard tissue section staining,and biomechanical tests.Results The modified ACDF ovine model was established successfully.There were no significant differences in important hematology indexes(P＞0.05)and histopathological analysis showed no pathological changes,such as inflammatory cell infiltration.The implants had good biosafety.Furthermore,X-ray and CT examinations showed that the position of internal fixation and the interbody fusion were good.Micro-CT and quantitative analysis at 3 and 6 months after operation showed that compared with PEEK Cage group,the bone volume/total volume and trabecular number were significantly increased(P＜0.01)while the trabecular spacing was significantly decreased in the new method Ti6Al4V and 3D-printed Ti6Al4V groups compared with the PEEK Cage group(P＜0.01).Moreover,the new method new method Ti6Al4V Cage group had more bone growth(P＜0.01).Hard tissue section staining demonstrated that the pores of the new method Ti6Al4V Cage and 3D-printed Ti6Al4V Cage had obvious bone growth and relatively dense pores in the new method Ti6Al4V and 3D-printed Ti6Al4V groups,and the combination was slightly better than that of PEEK Cage.Biomechanical evaluation indicated that the new method Ti6Al4V Cage and 3D-printed Ti6Al4V Cage reduced the range of cervical flexion-extension,lateral bending,and axial rotation(P＜0.05)compared with the PEEK cage,as well as enhancing the stability of the cervical vertebra,and the new method Ti6Al4 V Cage was more advantageous(P＜0.05).Conclusions After the establishment of the modified ACDF ovine model,reasonable and effective assessment method were used to demonstrate the suitability and effectiveness of the model and the good biosecurity of all three Cage materials.Compared with the PEEK Cage,the new method Ti6Al4V Cage and 3D-printed Ti6Al4V Cages showed better performances in terms of bone growth and bone fusion,which could enhance the stability of the cervical vertebrae.The new method Ti6Al4V Cage was particularly advantageous.

Objective: To investigate the impact of childhood traumatic experiences on individual risktaking decisions in early adulthood using functional nearinfrared spectroscopy (fNIRS), so as to provide the reference for clarifying the brain mechanisms underlying the impact of childhood trauma on individual risky decision. Methods: From December 2023 to March 2024, 28 children with childhood trauma experiences (trauma group) and 32 healthy college students (control group) were selected from Jining Medical University by a combination of stratified descent and convenient sampling methods. All subjects participated in the Iowa Game task fNIRS scanning. The brain activation, functional connectivity, graph theory properties (degree centrality, betweenness centrality, and local efficiency), and Receiver Operating Characteristic (ROC) analysis were performed by using preprocessing fNIRS data. Results: Compared with control group, trauma group showed significantly fewer choice times in the inferior deck (Z=-0.88), and showed significantly decreased activation levels in the right frontalpolar (Z=-2.59), as well as showed significant decreased functional connectivity between left dorsolateral prefrontal and in right dorsolateral prefrontal (Z=-3.78), and between left dorsolateral prefrontal cortex and the right frontal pole (Z=-3.68)(P<0.05). The central index of right inferior frontal gyrus in the trauma group was higher than that in the control group, while the central index of left and right dorsolateral frontal lobes was lower than that in the control group (Z=2.13, -2.53, -2.12, P<0.05). The centrality index of the right inferior frontal gyrus in the trauma group was higher than that in the control group (Z=2.47, P<0.05). The local efficiency indicators of the right inferior frontal gyrus, left and right frontal pole in the trauma group were higher than those in the control group (Z=2.51, 2.17, 2.53, P<0.05). The results of the ROC curve analysis showed that the local efficiency achieved the highest area under the curve (AUC=0.68). Conclusions Young adults with childhood trauma experience tend to choose lower loss, and the frontal pole shows a lack of activation in the whole process of risk decision performance. The abnormalities in the brain connectivity and network properties might be the neural basis of excessive defense mechanisms that childhood trauma leads to risky decisions.

This study investigated the primary pathogenesis and syndrome evolution of different heart failure with preserved ejection fraction(HFpEF)stages based on the classical and clinical experience of traditional Chinese medicine(TCM),combined with the clinical characteristics of pre-heart failure,symptomatic heart failure,and advanced heart failure.This study summarizes and refines the three core syndrome factors:water,deficiency and blood stasis.Water-fluid retention was observed throughout these three stages,from the beginning to the end.With the advancement of the disease,the heart yang changes from stagnation to deficiency,water-fluid retention gradually increases,blood stasis becomes increasingly prominent,and the disease location develops dynamically from the upper to the middle and lower jiao.This study proposes three methods of treating HFpEF.The main pathogenesis of pre-heart failure is lung qi dysfunction-induced water retention,which can be treated by dispersing lung qi and transforming water retention using Fuling Xingren Gancao Decoction.The primary pathogenesis of symptomatic heart failure is yang and qi deficiency-induced water retention,which can be treated with tonifying yang,supplementing qi,and transforming water retention using Shengxian Decoction combined with Linggui Zhugan Decoction.The primary pathogenesis of advanced heart failure is yang deficiency with blood stasis and water retention affecting the heart,which can be treated with tonifying yang,circulating blood,and expelling water retention using Zhenwu Tingli Decoction.Chinese medicine can be flexibly added or subtracted according to the patients'concurrent patterns.However,the daily care of patients should be considered.This study explores the staging treatment of HFpEF from water,deficiency and blood stasis to provide a TCM clinical reference for treating HFpEF.

Objective:To explore the cutoff value for assessing small airway dysfunction in children with asthma.Methods:A total of 364 asthmatic children aged 5 to 14 years, with normal ventilatory function, followed up at the Asthma Clinic of the Children′s Hospital of Capital Institute of Pediatrics from January 2017 to January 2018, were selected as the case group. Concurrently, 403 healthy children of the same age range and without any symptoms in the community were chosen as the control group, and pulmonary function tests were conducted. The values of forced expiratory volume in 1 second (FEV 1), forced vital capacity (FVC), forced expiratory flow at 50% of FVC (FEF 50), forced expiratory flow at 75% of FVC (FEF 75) and maximum mid-expiratory flow (MMEF) were compared between case group and control group. Statistical tests such as t-test, χ2 test, or Mann-Whitney U test were used to analyze the differences between the groups. Receiver operating characteristic (ROC) curves were constructed, and the maximum Youden Index was utilized to determine the optimal cutoff values and thresholds for identifying small airway dysfunction in asthmatic children. Results:This study comprised 364 children in the case group (220 boys and 144 girls) and 403 children in the control group (198 boys and 205 girls). The small airway parameters (FEF 50%pred, FEF 75%pred, MMEF%pred) in the asthmatic group were significantly lower than in the control group (77% (69%, 91%) vs. 95% (83%, 109%), 67% (54%, 82%) vs. 84% (70%, 102%), 76% (66%, 90%) vs. 97% (86%, 113%), Z=12.03, 11.35, 13.66, all P<0.001). The ROC curve area under the curve for FEF 50%pred, FEF 75%pred, MMEF%pred was 0.75, 0.74, and 0.79, respectively. Using a cutoff value of 80% for FEF 50%pred achieved a sensitivity of 56.9% and specificity of 81.4%. A cutoff value of 74% for FEF 75%pred resulted in a sensitivity of 67.3% and specificity of 69.2%. Finally, using a cutoff value of 84% for MMEF%pred achieved a sensitivity of 67.9% and specificity of 77.2%. Conclusion:In the presence of normal ventilatory function, utilizing FEF 50<80% predicted or MMEF<84% predicted can accurately serve as criteria for identifying small airway dysfunction in children with controlled asthma.

Objective To explore the clinical value of serum protein kinase N1(PKN1),tumor necrosis factor receptor superfamily member 4(TNFRSF4),and DNA damage-inducible transcription factor 4(DDIT4)in predicting lymph node metastasis and prognosis of patients with endometrial cancer.Methods A total of 180 cases of endometrial cancer patients treated in Tangshan Maternal and Child Health Hospital from October 2019 to October 2021 were selected as endometrial cancer group.In addition,180 patients with benign uterine diseases treated in this hospital during the same period were selected as the benign disease group,and 180 healthy patients who underwent physical examination in this hospital were selected as the healthy group.The endometrial cancer group was divided into 42 cases with lymph node metastasis and 138 cases without lymph node metastasis according to whether lymph node metastasis occurred.The patients were divided into poor prognosis group and good prognosis group according to the follow-up results.The levels of serum PKN1,TNFRSF4 and DD1T4 in each group were compared,the influencing factors of patient prognosis were analyzed by Logistic model,and the predictive value of serum PKN1,TNFRSF4 and DDIT4 on prognosis of patients was analyzed by drawing the receiver operating characteristic curve.Results Compared with the healthy group,the levels of serum PKN1 and DDIT4 in endometrial cancer group and benign disease group were in-creased,and the levels of serum TNFRSF4 were decreased,with statistical significance(P＜0.05).The serum levels of PKN1 and DDIT4 in lymph node metastasis group were higher than those in no lymph node metasta-sis group,and the levels of TNFRSF4 were lower than those in no lymph node metastasis group,with statisti-cal significance(P＜0.05).The proportion of poor prognosis group with low differentiation degree,positive lymphovascular space invasion and myometrial infiltration≥1/2 was higher than that of good prognosis group,and the difference was statistically significant(P＜0.05).The levels of serum PKN1 and DDIT4 in the poor prognosis group were higher than those in the good prognosis group,and the levels of TNFRSF4 were lower than those in the good prognosis group,with statistical significance(P＜0.05).Serum PKN1,DDIT4,LVSI and myometrial infiltration were risk factors for the prognosis of endometrial cancer,and serum TN-FRSF4 was protective factor for the prognosis of endometrial cancer(P＜0.05).Serum PKN1,TNFRSF4 and DDIT4 combined predicted the prognosis of patients with endometrial cancer more effectively than each serum index alone(P＜0.05).Conclusion Serum PKN1,TNFRSF4 and DDIT4 are related to lymph node metasta-sis and prognosis of patients with endometrial cancer,and have high predictive efficacy for patient prognosis.

OBJECTIVE To explore the distribution pattern of traditional Chinese medicine(TCM)syndrome types of primary o-varian insufficiency(POI)sleep disorders and the differences in the distribution of sleep quality index among different syndrome types,in order to provide a basis for syndrome differentiation treatment and prevention of POI associated with sleep disorders.METHODS 600 POI patients who met the inclusion criteria were collected for epidemiological investigation,and 405 patients who met the diagnosis of sleep disorders were selected as the research group.The patients'general information,TCM four diagnosis and sex hormone level in-formation were collected,and the Pittsburgh sleep quality index(PSQI)scale was used to evaluate patients'sleep conditions,and ana-lyze the characteristics and influencing factors of TCM syndrome types of POI associated with sleep disorders.RESULTS The main TCM syndrome types of POI accompanied by sleep disorders were heart and kidney disharmony syndrome(41.98%),spleen and kid-ney yang deficiency syndrome(22.22%),kidney deficiency and liver stagnation syndrome(20.99%),and kidney deficiency and blood stasis syndrome(14.81%).The heart and kidney disharmony syndrome had the longest sleep latency and shortest sleep time,relied more on hypnotic drugs,and had the highest PSQI total score;the heart and kidney disharmony syndrome and kidney deficiency and liver stagnation syndrome had the worst sleep quality;the spleen kidney yang deficiency syndrome had the highest daytime dysfunc-tion score.There was no significant difference in FSH levels among different TCM syndrome types;the distribution of E2 values from low to high was:heart and kidney disharmony syndrome,kidney deficiency and liver stagnation syndrome,spleen and kidney yang de-ficiency syndrome,and kidney deficiency and blood stasis syndrome,and there were significant differences among multiple groups(P<0.05).CONCLUSION The main TCM syndrome types of patients with POI and sleep disorders are heart and kidney disharmony syn-drome,spleen and kidney yang deficiency syndrome,kidney deficiency and liver stagnation syndrome,and kidney deficiency and blood stasis syndrome.Among them,the most common TCM syndrome type with the worst sleep quality is heart and kidney disharmony syn-drome,which may be closely related to estrogen E2 levels.
