Objective To examine the impact and partial mechanism of bupivacaine sustained-release drug(code PB21)in combination with low-dose dexamethasone(Dex)on the analgesic time of rats with knee osteoarthritis(KOA).Methods Using the techniques of anterior cruciate ligament transection and meniscus instability,a rat KOA model was created.After eight weeks,SD mice were split into three groups at random:a group for the model,one for Dex(50 μg),one for PB21(1.5 mg),and one for combined administration(1.5 mg PB21/50 μg Dex),with a control group that received a sham operation.The pain thresholds of KOA rats were measured using a Pres-sure Application Measurement(PAM)at different intervals before to delivery and 4,24,36,and 48 hours following administration;to gauge changes in discomfort,a CatWalk was used to assess the rats'average foot strength and maximum contact area before,four,twenty-four,and forty-eight hours after treatment.A portion of the rats were put to sleep at four,twenty-four,and forty-eight hours following the injection,and the joint synovium was removed for paraffin sectioning.Immunohistochemistry was used to identify the expression of GAP43 in the synovium,whereas immunofluorescence was used to identify the expression of CGRP in the same tissue.Results The average strength and maximum contact area of the foot and claw decreased(P＜0.01),and the pain threshold decreased(P＜0.01)in the model group compared to the sham operation group.The PB21+Dex group experienced a delayed pain threshold lowering time delay when compared to the PB21 and Dex treatment groups alone.Up to 48 hours lat-er,the combination administration group's average strength and maximum contact area of the foot paw remained ele-vated,and there was a statistically significant difference(P＜0.05)between the combined administration group and PB21 and Dex alone.GAP43 and CGRP expression levels in synovial tissue were detected.The results indica-ted that PB21 and Dex alone could lower protein expression levels at 4 and 24 h at the two time points,and that the PB21+Dex group could still significantly lower GAP43 and CGRP expression levels at 48 h.At the 48 h time point,the PB21+Dex group was statistically significant when compared to the PB21 and Dex alone administration group(P＜0.05).Conclusion In summary low dose dexamethasone can prolong the analgesic effect of PB21 on KOA rats,which is connected to reducing the expression of pain related proteins CGRP and GAP43.

Objective To address the challenges of poor performance and lack of interpretability in existing models,the SHAP algorithm is used to develop an interpretable machine learning model that offers a novel approach to wound age estimation,Methods Based on the previous discovery of the expression of 35 wound age healing-related genes in contused skeletal muscle,the woun age estimaton model was constructed using four algorithms,namly,Multilayer Perceptron(MLP),Random Forest(RF),LightGBM(LGBM),and Support Vector Machine(SVM).The SHAP(Shapley Additive Explanation)algorithm was used to rank the importance of genetic features,eliminate redundant attributes,and optimize the model for accurate wound age estimation.the genetic features of the optimal model were analyzed using SHAP's local interpretation capabilities.Results The best results were obtained using model of MLP(area under the curve(AUC)=0.99)The wound ages were classified into four categories:4～12 h,16～24 h,28～36 h,and 40～48 h,using only 15 gene features.According to SHAP analysis,Fam210a was identified as the most relevant gene.Local analysis revealed that high expression of Fam210a contributed to an increase in the predicted probability of 4 h～12 h,while high expression of Rae1 contributed to an increase in the predicted probability of 16 h～24 h.Additionally,low expression of Tbx18 contributed to an increase in the predicted probability of 28 h～36 h,whereas high expression of Tbx18 contributed to an increase in the predicted probability of 40 h～48 h.Conclusions The combined MLP and SHAP model can be used to predict wound age.Using the SHAP interpreter can better understand the degree of contribution of feature genes to the model prediction,and lay the foundation for further in-depth study of wound age estimation.

Objective:To investigate the status of fear of progression (FoP) in patients with esophageal gastric variceal bleeding (EGVB) due to liver cirrhosis and analyze its influencing factors.Methods:A convenience sampling method was used to select 210 patients with liver cirrhosis and EGVB who were hospitalized at Shanxi Bethune Hospital and Shanxi Provincial People's Hospital between May and December 2023. Data were collected using a general information questionnaire, the Fear of Progression Questionnaire-Short Form (FoP-Q-SF), the Brief Illness Perception Questionnaire (BIPQ), the Medical Coping Modes Questionnaire (MCMQ), and the Perceived Social Support Scale (PSSS) .Results:A total of 210 questionnaires were distributed and 200 valid questionnaires were recovered, with a valid recovery rate of 95.24%. Among 200 EGVB patients, the FoP-Q-SF score was (31.82±10.02). Multiple linear regression analysis showed that gender, number of bleeding episodes, illness perception, coping strategies, and social support were significant influencing factors of FoP in these patients ( P<0.05) . Conclusions:The incidence of FoP is relatively high in patients with liver cirrhosis and EGVB. Healthcare providers should pay attention to the impact of gender, bleeding episodes, illness perception, coping strategies, and social support on FoP and implement targeted interventions to reduce its levels.

Objective To explore the prescription law of Professor Wang Yinglin for treating pediatric cough based on the Carma algorithm and complex network.Methods The prescriptions of children with cough as the chief complaint who were treated by Professor Wang in the outpatient department from November 2022 to May 2023 were taken as the research object.Carma algorithm and complex network were used to analyze the main prescriptions of Professor Wang for treating children's cough,and explore the prescription law of Professor Wang for treating children's cough.Results A total of 420 cases were included,with an average age of 6.5 years old.Among them,there were 158 males and 262 females,involving 420 prescriptions,97 kinds of Chinese materia medica,a total frequency of 4 665,and 37 drugs with a frequency of use>20.By analyzing the drug combination derived from Carma analysis of algorithms and clinical verification,it was found that Professor Wang commonly used two drug combinations to treat children's cough:Poria-Exocarpium Citri Rubrum,Scrophulariae Radix-Imperatae Rhizoma,Peucedani Radix-Cynanchi Stauntonii Rhizoma,Perillae Fructus-Asteris Radix,Saposhnikoviae Radix-Liquidambaris Fructus;three medicine combination:Perillae Fructus-Asteris Radix-Semen Lepidii,Poria-Cablin Potchouli Herb-Exocarpium Citri Rubrum,Magnoliae Flos-Saposhnikoviae Radix-Liquidambaris Fructus;the combination of four drugs included Poria-Scrophulariae Radix-Exocarpium Citri Rubrum-Imperatae Rhizoma,Poria-Adenophorae Radix-Exocarpium Citri Rubrum-Scrophulariae Radix;five medicine combinations:Poria-Scrophulariae Radix-Exocarpium Citri Rubrum-Imperatae Rhizoma-Adenophorae Radix,Poria-Scrophulariae Radix-Exocarpium Citri Rubrum-Imperatae Rhizoma-Cablin Potchouli Herb;six medicine combinations:Poria-Scrophulariae Radix-Exocarpium Citri Rubrum-Imperatae Rhizoma-Adenophorae Radix-Folium Eriobotryae,Poria-Scrophulariae Radix-Exocarpium Citri Rubrum-Imperatae Rhizoma-Adenophorae Radix-Isatidis Radix,Poria-Scrophulariae Radix-Exocarpium Citri Rubrum-Imperatae Rhizoma-Cablin Potchouli Herb-Saposhnikoviae Radix,Folium Eriobotryae-Perillae Fructus-Asteris Radix-Semen Lepidii-Peucedani Radix-Cynanchi Stauntonii Rhizoma,Glehniae Radix-Crataegi Fructus-Stemonae Radix-Bulbus Lilii-Bulbus Fritillariae Cirrhosae-Ophiopogonis Radix.Complex network analysis found that the core drugs were:Adenophorae Radix,Poria,Exocarpium Citri Rubrum,Scrophulariae Radix,Imperatae Rhizoma,Folium Eriobotryae,Bulbus Fritillariae Thunbergii,Isatidis Radix,Peucedani Radix,Cynanchi Stauntonii Rhizoma,Stemonae Radix,Bambusae Concretio Silicea,Cablin Potchouli Herb.Five core prescriptions were obtained by multi-scale backbone network analysis.Conclusion Professor Wang's treatment of pediatric cough varies depending on the medical history,symptoms,and location of the disease,with different prescriptions.New diseases are often considered based on pathogenic factors,with phlegm heat as the main treatment,and the efficacy is mostly achieved by purging the lungs and resolving phlegm;phlegm heat gradually subsides,and residual pathogens are not cleared.The main approach is to eliminate residual pathogens and replenish qi and yin;long term illness mainly focuses on supplementing qi and nourishing yin.

Objective: To explore the prevalence and relevant factors of physical and emotional abuse by parents among children with autism spectrum disorder (ASD), so as to provide basis for intervention program of children abuse. Methods: A total of 221 ASD children from 3 special education institutions in Tangshan were investigated from March to October in 2021, 395 non ASD children from two kindergartens in urban and rural areas were selected by convenient sampling. Parents of these children were invited for online and on site questionnaire survey. The self designed violence questionnaire, Childhood Autism Rating Scale and Patient Health Questionnaire-9 were used to assess violence, severity of autism, depression of parents. Chi square test, Fisher s exact probability method and Logistic regression were used to analyze the influencing factors of violence. Results: About 81.9% of children with ASD and 72.9% of non ASD children experienced violence( P <0.05). The reported rates of physical and emotional violence in ASD children were 74.2% and 73.8% respectively, which in non ASD children were 58.7% and 65.8% respectively. There were significant differences in the 3 types of violence rate between the two groups ( P <0.05). Multivariate Logistic regression analysis showed that boys ( OR =1.70, 95% CI =1.12-2.60), annual per capita income <10 000 yuan( OR =2.43, 95% CI =1.45- 4.08 ), and parental depression ( OR mild =11.01, 95% CI =5.38-22.49; OR moderate =69.97，95% CI =24.25-201.93) were the risk factors for child violence exposure; ASD disease ( OR=1.96，95%CI =1.32-2.92), older age ( OR=1.19, 95%CI =1.01-1.41) and parental depression( OR mild =7.83, 95% CI =3.67-16.74; OR moderate =14.37，95% CI =6.17-33.46) were risk factors for physical violence; boys ( OR =1.62, 95% CI =1.11-2.36), mothers who work in manual labor ( OR=1.68, 95%CI =1.09-2.59) and parental depression ( OR mild =7.69, 95% CI =3.74-15.81; OR moderate =25.37, 95% CI =10.80-59.63) were risk factors for emotional violence( P < 0.05 ). Conclusion The reported rate of parental violence against children with ASD is high. Mental health promotion and social support for families with ASD should be strengthened.

During coronavirus disease 2019 epidemic, the treatment of severe trauma has been impacted. The Consensus on emergency surgery and infection prevention and control for severe trauma patients with 2019 novel corona virus pneumonia was published online on February 12, 2020, providing a strong guidance for the emergency treatment of severe trauma and the self-protection of medical staffs in the early stage of the epidemic. With the Joint Prevention and Control Mechanism of the State Council renaming "novel coronavirus pneumonia" to "novel coronavirus infection" and the infection being managed with measures against class B infectious diseases since January 8, 2023, the consensus published in 2020 is no longer applicable to the emergency treatment of severe trauma in the new stage of epidemic prevention and control. In this context, led by the Chinese Traumatology Association, Chinese Trauma Surgeon Association, Trauma Medicine Branch of Chinese International Exchange and Promotive Association for Medical and Health Care, and Editorial Board of Chinese Journal of Traumatology, the Chinese expert consensus on emergency surgery for severe trauma and infection prevention during coronavirus disease 2019 epidemic ( version 2023) is formulated to ensure the effectiveness and safety in the treatment of severe trauma in the new stage. Based on the policy of the Joint Prevention and Control Mechanism of the State Council and by using evidence-based medical evidence as well as Delphi expert consultation and voting, 16 recommendations are put forward from the four aspects of the related definitions, infection prevention, preoperative assessment and preparation, emergency operation and postoperative management, hoping to provide a reference for severe trauma care in the new stage of the epidemic prevention and control.

Terpine-4-ol is abundant in nature. As a cyclic monoterpenoid compound， terpine-4-ol is distributed in a variety of natural plants. It is the main component and the key active substance in many traditional Chinese essential oils， such as Melaleuca alba essential oil and coral ginger essential oil. Terpine-4-ol has anti-microbial， anti-tumor， insecticidal， anti-inflammatory， and other effects. It can treat cancer， as well as oral and cardiovascular diseases with great safety. In terms of antibacterial activity， terpine-4-ol can destroy bacterial cell walls， improve membrane permeability， and regulate bacterial migration， reproduction， and other related genes to inhibit bacterial activity. In terms of antifungal activity， terpine-4-ol can bind with ergosterol in fungal cell walls to cause fungal death. In terms of insecticidal activity， terpine-4-ol can inhibit Na⁺ and K⁺-ATPase activity and cause the death of the insect. In terms of anticancer activity， terpine-4-ol can regulate the expression of apoptosis-related proteins in cancer cells， so as to control the apoptosis of cancer cells. In this paper， the pharmacological activity and action mechanism of terpine-4-ol were reviewed to provide a reference for further research and utilization of terpine-4-ol.

Objective:To explore the value of monocyte subsets and CD64 expression in the diagnosis and prognosis of sepsis.Methods:A prospective case-control study was designed. 30 septic patients and 30 non-septic patients who were admitted to the intensive care unit (ICU) of the PLA Army Characteristic Medical Center from March 2021 to March 2022 were enrolled. After 1, 3, and 5 days of ICU admission, peripheral blood samples were taken from patients. Flow cytometry was used to detect the proportion of monocyte subsets and the expression level of CD64 on the surface, and the difference of expression between patients in two group was analyzed. The risk variables for sepsis were analyzed using single-factor and multi-factor Logistic regression. The diagnostic efficacy of each risk factor for sepsis was determined using the receiver operator characteristic curve (ROC curve).Results:One day after ICU admission, the proportions of monocytes and classic monocytes in white blood cells (WBC) of septic patients were significantly lower than those of non-septic patients [proportion of monocytes to WBC: (4.13±2.03)% vs. (6.53±3.90)%, proportion of classic monocytes to WBC: 1.97 (1.43, 2.83)% vs. 3.37 (1.71, 5.98)%, both P < 0.05]. The proportion of non-classical monocytes in monocytes was significantly higher in septic patients than that in non-septic patients [(11.42±9.19)% vs. (6.57±4.23)%, P < 0.05]. The levels of CD64 expression in monocytes, classic monocytes, intermediate monocytes and non-classic monocytes were significantly higher in sepsis patients than those in non-septic patients [mean fluorescence intensity (MFI): 13.10±6.01 vs. 9.84±2.83 for monocytes, 13.58±5.98 vs. 10.03±2.84 for classic monocytes, 13.48±6.35 vs. 10.22±2.99 for intermediate monocytes, 8.21±5.52 vs. 5.79±2.67 for non-classic monocytes, all P < 0.05]. Multivariate Logistic regression research showed that CD64 in typical monocytes [odds ratio ( OR) = 1.299, 95% confidence interval (95% CI) was 1.027-1.471, P = 0.025] and the proportion of non-typical monocytes in monocytes ( OR = 1.348, 95% CI was 1.034-1.758, P = 0.027) were the independent risk factors for sepsis. ROC curve showed that the area under the ROC curve (AUC) of CD64 expression of classical monocytes, the fraction of non-classical monocytes in monocytes, and procalcitonin (PCT) in the diagnosis of sepsis was 0.871. A correlation analysis revealed a negative relationship between the acute physiology and chronic health status evaluation Ⅱ (APACHE Ⅱ) on the first, third, and fifth days following ICU admission and the expression level of CD64 in patients' classic monocytes ( r values were -0.264, -0.428 and -0.368, respectively, all P < 0.05). Conclusions:Combining the proportion of non-classical monocytes in monocytes, the level of plasma PCT, and the CD64 expression of classic monocytes in peripheral blood has good efficacy in identifying sepsis and assessing its severity.
