Osteoarthritis （OA） and stroke are common clinical diseases that reduce patients' quality of life and place a burden on families and society. Ruyi Zhenbaowan， a classic prescription in Tibetan medicine， have the functions of clearing heat， awakening the brain and opening orifices， relaxing tendons and promoting meridian circulation， and eliminating yellow water. Clinically， they are used to treat osteoarthritis， post-stroke sequelae， neuropathic pain， and other related conditions. Modern pharmacological studies have demonstrated their anti-inflammatory， analgesic， and nerve-repairing effects. However， current research remains insufficient regarding the appropriate indications， timing， and efficacy of this medicine in treating relevant diseases. To enhance clinicians' understanding of this medicine and promote its standardized and rational clinical use， a panel of national experts， including clinical specialists， Tibetan medicine practitioners， pharmacologists， and methodologists， formulated this consensus based on clinical experience and evidence-based practice. The Cochrane systematic review framework， the Grading of Recommendations Assessment， Development and Evaluation （GRADE） system， and the nominal group method were employed to generate seven graded recommendations and 19 consensus-based suggestions. These recommendations clearly define the key points in the clinical application of Ruyi Zhenbaowan， including therapeutic indications， dosage and administration， treatment duration， and medication safety. The consensus specifically addresses the clinical efficacy， appropriate timing of administration， dosage strategies， treatment cycles， and combination medication strategies for treating osteoarthritis and stroke and provides an overview of safety considerations. The aim is to provide standardized guidance for hospitals and healthcare institutions nationwide to ensure the rational application of Ruyi Zhenbaowan in the treatment of osteoarthritis and stroke， reduce medication-related risks， and further leverage its clinical advantages. This consensus has been approved and issued by the China Association of Chinese Medicine， with the standard number GS/CACM 369-2024.

ObjectiveTo investigate the mechanism of the modified of Bazhentang combined with Guishentang in improving pregnancy outcomes in mouse models of embryo implantation dysfunction by regulating T helper 1/T helper 2 （Th1/Th2） immune balance. MethodsEighty ICR female mice were randomly divided into four groups （n=20 per group） on gestational day 1 （GD1）： control， model， western medicine， and traditional Chinese medicine （TCM） groups. Except for the control group， all mice received mifepristone solution （0.2 mg/mouse） via oral gavage on GD4 to induce embryo implantation dysfunction. The TCM group received a water decoction of the modified of Bazhentang combined with Guishentang （20.8 g·kg^-1）， with the western medicine group administered dydrogesterone （3.9 mg·kg^-1）， and the control/model groups given equal volumes of saline. All treatments were administered once daily from GD1 until one day before sample collection. Outcomes included implantation site counts （macroscopic observation）， pregnancy rates， body weight， endometrial histopathology （hematoxylin-eosin staining）， uterine expression of T-box expressed in T cells （T-bet）， GATA-binding protein 3 （GATA3）， interferon gamma （IFN-γ）， and interleukin-4 （IL-4） at protein （Western blot） and mRNA （real-time polymerase chain reaction， Real-time PCR） levels， serum IFN-γ and IL-4 levels （enzyme-linked immunosorbent assay， ELISA）， and Th1/Th2 immune balance evaluated by calculating T-bet/GATA3 and IFN-γ/IL-4 ratios. ResultsCompared to the control group， the model group showed no significant change in pregnancy rate but exhibited a marked reduction in average implantation sites and body weight （P<0.01）. Histopathological analysis revealed endometrial abnormalities， including decreased glandular density， stromal compaction， and absence of nucleolar vacuoles. At the molecular level， uterine tissue in the model group demonstrated significantly upregulated expression of T-bet and IFN-γ （P<0.05， P<0.01）， alongside markedly downregulated GATA3 and IL-4 expression （P<0.05， P<0.01）. Serum analysis confirmed markedly elevated IFN-γ （P<0.01） and reduced IL-4 levels （P<0.01）， resulting in significantly increased T-bet/GATA3 and IFN-γ/IL-4 ratios （P<0.01）. Compared to the model group， pregnancy rates in all treatment groups showed no significant change. Implantation sites and body weight increased substantially （P<0.01）， with restored endometrial morphology characterized by enhanced glandular density， stromal edema， and reappearance of nucleolar vacuoles. Significant downregulation of T-bet and IFN-γ （P<0.01） and upregulation of GATA3 and IL-4 （P<0.05， P<0.01） in uterine tissue were observed. Serum IFN-γ levels were significantly reduced （P<0.05， P<0.01）， while IL-4 levels were significantly elevated （P<0.05）. The Th1/Th2 ratios were significantly decreased （P<0.01）. ConclusionThe modified of Bazhentang combined with Guishentang significantly enhances the number of embryo implantation sites in mice with embryo implantation dysfunction， potentially through modulating T-bet/GATA3 expression， restoring Th1/Th2 immune balance， and improving endometrial receptivity.

BackgroundGraduate students frequently face life events， many of which may adversely affect their mental well-being. However， the interaction between life events and the development of depression， anxiety， and somatic symptoms remains unclear. ObjectiveTo explore the relationship between life events and the development of depressive， anxiety and somatic symptoms in graduate students， thereby informing prevention strategies for these conditions. MethodsA sample of 6 722 newly enrolled graduate students at a comprehensive university in Southwest China from September to November 2018 was selected. The assessment was conducted using the Adolescent Self-rating Life Events Checklist （ASLEC）， the 7-item Generalized Anxiety Disorder scale-7 item （GAD-7）， the Patient Health Questionnaire Depression Scale-9 item （PHQ-9）， and the Patient Health Questionnaire-15 （PHQ-15）. Network analysis was implemented by using the bootnet and qgraph packages in the R software （version 4.2.3）， with centrality indices calculated to identify core and bridge symptoms within the network. ResultsThe study encompassed a total of 6 171 graduate students， representing 91.80% of the target population. The prevalence rates of anxiety， depressive， and somatic symptoms among graduate students were 12.59% （777/6 171）， 16.63% （1 026/6 171）， and 27.66% （1 707/6 171）， respectively. Network analysis revealed that 'academic stress' was the core symptom with the highest strength and expected influence （both values=1.207）， while 'feeling down， depressed， or hopeless' was the bridge symptom with the highest bridge strength and bridge expected influence （both values=0.454）. There was no significant difference in global network strength and edge weight between women and men （P>0.05）. ConclusionAcademic stress， emerging as the core symptom， assumes a dominant position within the symptom network and exhibits strong interactions with other negative affective states. There was no gender difference in the network structure.

Objective To investigate the effects of dynamic lung compliance(Cdyn)-guided indi-vidual positive end-expiratory pressure(PEEP)titration on pulmonary function in elderly patients undergoing laparoscopic colorectal cancer surgery.Methods Sixty-eight elderly patients were selected for laparoscopic radical resection of colorectal cancer,37 males and 31 females,aged 65-79 years,BMI<30 kg/m2,ASA physical status Ⅱ or Ⅲ.The patients were divided into two groups using the random number table method:individualized PEEP group(group P)and control group(group C),34 patients in each group.In group P,the patients received recruitment maneuvers and PEEP titration test at immediately after intubation,immediately after establishing pneumoperitoneum-Trendelenburg position and immediately after pneumoperitoneum.The patients in group C received PEEP 5 cmH2 O during procedure.The three best titra-tion PEEP and the actual tidal volume(VT)in group P were also recorded.PaO2,PaCO2,PETCO2 10 mi-nutes after the tracheal intubation(T1),10 minutes(T2)and 1 hour(T3)after establishing pneumoperito-neum-Trendelenburg position,at the end of the surgery but before extubation(T4)were recorded,and the oxygenation index(OI),physiological dead space to tidal volume(Vd/VT),alveolar arterial oxygen differ-ence(A-aDO2),driving pressure,and Cdyn were calculated.Concentrations of interleukin-8(IL-8),tumor necrosis factor-α(TNF-α),Clara cell secretoyr protein(CC16)and lung alveolar surface active sub-stances-D(SP-D)in the serum samples were determined by ELISA before anesthesia induction(T0)and 10 minutes after extubation(T5).Postoperative pulmonary complications(PPCs)were also recordrd.Results The individualized PEEP of Cdyn?guided PEEP titration was 4 cmH2O. Compared with group C, the PaO2 and OI in group C were significantly increased at T4, the Cdyn was significantly increased at T1,T3, and T4, the driving pressure was significantly decreased at T1 -T4, the serum concentration of CC16 was significantly decreased at T5 ( P < 0. 05). There were no significant differences in PaCO2, PET CO2,A?aDO2, and Vd/ VT between the two groups. There was no severe PPCs in the two groups. Conclusion Pressure?controlled ventilation modes combined with Cdyn?guide PEEP titration can increase the Cdyn, reduce thedriving pressure, and improve OI at the end of the operation, reduce the concentrations of CC16 at postop?eration, improve pulmonary function in elderly patients undergoing laparoscopic colorectal cancer surgery.

Objective To observe the manifestations of adult adrenal glands in intraoperative ultrasound(IOUS).Methods A total of 71 patients who underwent surgery for liver,biliary or pancreatic lesions were enrolled.Adrenal glands manifestations in IOUS were observed,and the displaying rate and the measured thickness of adrenal glands of IOUS were compared with those of CT/MRI.Results Adult adrenal gland manifested as bilateral weak echogenic structures with clear boundary and irregularly shape in IOUS.CT/MRI displaying rate of adrenal gland was 97.18％(138/142),of IOUS was 95.07％(135/142).IOUS displaying rate of the left side adrenal gland was 97.18％(69/71),of the right side adrenal gland was 92.96％(66/71),including 4 adrenal glands not shown on CT/MRI.The thickness of adrenal gland measured with IOUS was greater than those with CT/MRI(all P＜0.05).Conclusion IOUS of Adult adrenal glands present as bilateral weak echogenic structures with clear boundary and irregularly shape.IOUS displaying rate of adult adrenal gland was higher of the left side than the right side.

Purpose To observe the right ventricle and left ventricle blood pool T2 map in chronic thromboembolic pulmonary hypertension(CTEPH)and healthy controls,and to analyze the value of T2 mapping technique in evaluating CTEPH.Materials and Methods A total of 42 patients with CTEPH and 42 healthy volunteers had been prospectively recruited from January 2020 to January 2022 in China-Japan Friendship Hospital.All CTEPH patients underwent cardiac magnetic resonance with T2 mapping and right heart catheterization.Cardiac magnetic resonance was performed on healthy controls.Diastolic T2 mapping was performed in cardiac magnetic resonance,and then the ratio of right ventricular to left ventricular T2 values(RVT2/LVT2)between the CTEPH group and the healthy group was calculated and compared.Meanwhile,the correlation between RVT2/LVT2 and hemodynamic parameters in the CTEPH group was analyzed.Results RVT2/LVT2 in the CTEPH group was significantly lower than that in the healthy group(0.74±0.16 vs.0.86±0.12;t=3.673,P<0.001).RVT2/LVT2 in CTEPH group was negatively correlated with pulmonary vascular resistance(r=-0.534,P<0.001);while it was positively correlated with cardiac index,right atrium oxygen saturation,right ventricle oxygen saturation and pulmonary arteries oxygen saturation(r=0.600,0.603,0.648,0.582,P<0.001).Conclusion RVT2/LVT2 in the CTEPH group is positively correlated with right cardiac oxygen saturation and negatively correlated with pulmonary vascular resistance.T2 mapping may be a noninvasive evaluation of hemodynamics in CTEPH.

OBJECTIVE To analyze the influential factors for rivaroxaban-induced bleeding events in patients with non- valvular atrial fibrillation （NVAF） and coronary heart disease. METHODS A total of 64 hospitalized patients with NVAF complicated with coronary heart disease who were treated with rivaroxaban and admitted to the Fuzhou University Affiliated Provincial Hospital from November 2021 to May 2023 were included in this retrospective study. The demographic data， laboratory test indexes and other general clinical data， and steady-state trough concentration of rivaroxaban were collected， and the dose- adjusted trough concentration was calculated. The occurrence of bleeding events within 6 months after discharge was recorded. The univariate analysis and binary Logistic regression analysis were adopted to determine the independent risk factors of rivaroxaban- related bleeding events. The binary Logistic regression equation was constructed to predict the probability of bleeding events. The area under the receiver operator characteristic （ROC） curve （AUC） was used to analyze the predictive value of the regression equation. RESULTS Among 64 patients， 19 patients had 24 case-times bleeding events， most of which were mild bleeding （19 case-times， 79.2%）， and mainly gastrointestinal bleeding （17 case-times， 70.8%）. After symptomatic treatment and adjustment of the anticoagulant regimen， most of them were improved or cured. In the univariate analysis， the proportion of patients with a history of anemia， platelet count， urea nitrogen content， steady-state trough concentration of rivaroxaban， dose-adjusted trough concentration and coagulation indexes [international normalized ratio， prothrombin time （PT）， activated partial thromboplastin time] in bleeding group were significantly more or higher than those in non-bleeding group， while the albumin level was significantly lower than that in non-bleeding group （P＜0.05）. In binary Logistics regression analysis， high PT level （odds ratio＝1.473， 95% confidence interval＝1.103-1.967， P＝ 0.009） and high rivaroxaban dose-adjusted trough concentration （odds ratio＝1.174， 95% confidence interval＝1.018-1.355， P＝ 0.027） were independent risk factors for rivaroxaban-related bleeding events. The binary Logistic regression equation of bleeding event prediction probability （P） was LogitP＝－6.975+0.387×PT level+0.161×dose-adjusted trough concentration， and the AUC of the ROC curve was 0.825 （95% confidence interval was 0.708-0.909， P＜0.001）. CONCLUSIONS The risk factors of rivaroxaban-related bleeding events in patients with NVAF and coronary heart disease include previous anemia history， high platelet count， high urea nitrogen content， high rivaroxaban steady-state trough concentration， high dose-adjusted trough concentration， high coagulation indexes and low albumin level. High PT level and high dose-adjusted trough concentration are independent risk factors that can be used to predict the risk of rivaroxaban-induced bleeding events. The regression equation has good predictive value.

Objective To analyze the characteristics of newly-diagnosed occupational diseases among female workers in Foshan City from 2013 to 2023. MethodsClinical data of newly-diagnosed occupational diseases among female workers in Foshan City from 2013 to 2023 were collected from the "Occupational Disease and Hazardous Detection Information System" subsystem of the "China Disease Prevention and Control Information System", and their distribution characteristics were analyzed using descriptive epidemiology. Results A total of 218 cases of newly-diagnosed occupational diseases among female workers in Foshan City were reported from 2013 to 2023, categorized into seven categories and 17 types. The median age and median length of exposure to occupational hazards among female workers were 45.1 and 7.8 years, respectively. The top three categories of newly-diagnosed cases were occupational diseases of the ear, nose, throat, and oral cavity (90 cases, all related to occupational noise-induced hearing loss), occupational chemical poisoning (61 cases), and occupational pneumoconiosis and other respiratory diseases (51 cases, including 50 cases with occupational pneumoconiosis). The newly-diagnosed cases were concentrated in Nanhai District, Shunde District, and Gaoming District, accounting for 75.2%. The newly-diagnosed cases were found in non-metallic mineral products manufacturing industry, metal products industry, and electrical machinery and equipment manufacturing industry, accounting for 50.9%. Enterprises of newly-diagnosed cases were mainly distributed in private enterprises and foreign-invested enterprises, accounting for 80.3%. The scale of enterprises of newly-diagnosed cases was mainly small- and medium-sized, accounting for 79.4%. Among the 218 cases, there were 21 cluster cases, involving 16 cases of occupational silicosis and five cases of occupational acute n-hexane poisoning, involving six manufacture industries, with 81.3% cases worked in sanitary ceramic products industry. Conclusion Occupational noise-induced deafness should be listed as a key occupational disease for female workers in Foshan City. Attention should be paid to the prevention of occupational diseases among middle-aged female workers in the non-metallic mineral products industry and small and medium-sized enterprises, and the cluster outbreaks of occupational pneumoconiosis.

Objective To investigate the epidemiological characteristics and spatial distribution characteristics of Clonorchis sinensis human infections in Guangdong Province from 2016 to 2022, so as to provide insights into formulation of the clonorchiasis control measures in the province. Methods Xinhui District of Jiangmen City, Longmen County of Huizhou City and Wengyuan County of Shaoguan City in Guangdong Province were selected as fixed surveillance sites for human clonorchiasis from 2016 to 2022, and additional 10% to 15% counties (districts) endemic for clonorchiasis were sampled from Guangdong Province as mobile surveillance sites each year from 2016 to 2022. A village (community) was randomly selected from each surveillance site according to the geographical orientations of east, west, south, north and middle, and subjects were randomly sampled from each village (community). C. sinensis eggs were detected in subjects’ stool samples using the Kato-Katz technique, and the prevalence and intensity of C. sinensis infections were calculated. In addition, subjects’ gender, age, ethnicity, educational level and occupation were collected. The Guangdong Provincial 1:1 million electronic map in vector format was downloaded from the National Geomatics Center of China, and kernel density analysis and spatial autocorrelation analysis of C. sinensis human infections in Guangdong Province from 2016 to 2022 were performed using the software ArcGIS 10.7. Results A total of 153 188 residents were tested for C. sinensis infections in Guangdong Province from 2016 to 2022, including 75 596 men (49.35%) and 77 592 women (50.65%), and there were 5 369 residents infected with C. sinensis, with 3.50% overall prevalence of infections. The prevalence rates of severe, moderate and mild C. sinensis infections were 0.76%, 7.26% and 91.97% among C. sinensis-infected residents in Guangdong Province from 2016 to 2022, and there were age-, gender-, ethnicity-, occupation- and educational level-specific prevalence of C. sinensis human infections (χ² = 2 578.31, 637.33, 52.22, 2 893.28 and 1 139.33, all P values < 0.05). Global spatial autocorrelation analysis showed a cluster in the prevalence of C. sinensis human infections in Guangdong Province (Moran’s I = 0.63, Z = 27.31, P < 0.05). Kernel density analysis showed that the prevalence of C. sinensis human infections with a high kernel density in Guangdong Province was mainly distributed along the Zhujiang River basin in Pearl River Delta areas, followed by in eastern and northern Guangdong Province. In addition, local spatial autocorrelation analysis identified 73 high-high clusters of the prevalence of C. sinensis human infections in Guangdong Province. Conclusions The prevalence of C. sinensis human infections was high in Guangdong Province from 2016 to 2022, and mild infection was predominant among all clonorchiasis cases, with spatial clusters identified in the prevalence of C. sinensis human infections. Targeted clonorchiasis control measures are required among high-risk populations and areas.
