Objective To explore the scheme for the deployment and withdrawal of the surgical module of the new-type tent hospital system.Methods A set of standardized scheme for deploying and withdrawing the surgical module of the new-type tent hosital system was proposed and implemented in terms of labor division,operation precedure,operation technique and precaution.The operating time,number of operational errors and number of equipment damages were recorded for each of the five deployment and withdrawal operations before and after the program was executed,and the team members'immediate heart rate,percentage of maximum heart rate(MHR)and rating of perceived exercise(RPE)at the end of the operation were recorded after the program was implemented.SPSS 26.0 software was used for statistical analysis.Results The standardized scheme had the deployment time shortened from(85.15±11.430)min to(58.23±8.513)min,withdrawal time decreased from(65.36±9.369)min to(48.92±7.129)min,with the differences being statistically significant(P＜0.05);the numbers of operatio-nal errors and equipment damages were both reduced when compared with those before the implementation of the schemce;the immediate heart rate of the team members at the end of the operation ranged from 43 to 157 beats/min,with an average value of 151.1 beats/min,the individual MHR percentages were from 75％to 87％,with an average value of 81.1％,and the RPE scores were from 14 to 17,with an average value of 15.3,which all could be categorized as moderate-operation intensity.Condusion The standardized deployment and withdrawal scheme for the surgical module meets the needs of actual combat and training assessment,and thus is worthy promoting in medical institutions equipped with the surgical module of the new-type tent hosital system.[Chinese Medical Equipment Journal,2025,46(2):74-79]

Objective:To observe the preventive and treatment effects of warming needle therapy on peripheral neuropathy after albumin-bound paclitaxel plus cisplatin chemotherapy.Methods:Eighty patients who received albumin-bound paclitaxel plus cisplatin chemotherapy after being diagnosed with cancer were divided into an observation group and a control group using the simple random allocation table method,with 40 cases in each group.The control group received methylcobalamin dispersible tablets via oral administration,and the observation group received warming needle therapy.They were observed for the incidence of chemotherapy-induced peripheral neuropathy(CIPN),Levi's specific sensory neurotoxicity grading,brief pain inventory(BPI)score,nerve conduction velocities of the limbs,and traditional Chinese medicine(TCM)symptom scores before treatment,at the 21st day of the first cycle of chemotherapy(D1),and the 21st day of the second chemotherapy cycle(D2).The clinical efficacy was assessed at D2.Results:The incidence of CIPN was 92.5%in the control group,higher than 75.0%in the observation group(P<0.05).At D2,the number of people graded 0 on Levi's specific sensory neurotoxicity grading was larger in the observation group than in the control group,and the number of those graded 2 was smaller in the observation group(P<0.05);the observation group had a higher markedly effective rate than the control group(P<0.05).At D2,the BPI general score,BPI pain intensity score,and BPI pain interference score significantly dropped in the observation group compared to those before treatment(P<0.05).At D1,the motor nerve conduction velocity(MNCV)and sensory nerve conduction velocity(SNCV)of the limbs decreased in both groups compared to those before treatment;at D2,the MNCV and SNCV increased in the two groups compared to D1 and were higher in the observation group than in the control group(P<0.05).At D1,the TCM symptom scores increased in both groups compared to those before treatment,and the observation group was lower than the control group in comparing the scores of numbness in the extremities and poor appetite(P<0.05).At D2,the observation group showed decreases in all TCM symptom scores compared to D1 except for the scores of nausea and vomiting and poor appetite(P<0.05),while the control group had no significant changes in the TCM symptom scores compared to D1(P>0.05);the observation group was lower than the control group in comparing each symptom score(P<0.05).There were no significant adverse reactions in either group over the study period.Conclusion:Compared to oral administration of methylcobalamin dispersible tablets,warming needle therapy shows certain strengths in managing CIPN after albumin-bound paclitaxel plus cisplatin chemotherapy,and it can better improve chemotherapy-induced gastrointestinal reactions.

Aim To explore the antioxidative effect of the Chinese medicine Baitouweng(BTW)on treating ulcerative colitis(UC).Methods Sixty male mice were randomly divided into six groups:control,dextran sulfate sodium(DSS)(3 g·105 L-1),BTW(20,10,and 5 g·kg-1),and 5-aminosalicylic acid(5-ASA)(800 mg·kg-1).UC model was constructed by 3％DSS for seven days,and the UC model was given by ga-vage once daily from the 5 th day of modeling for seven days.Results BTW effectively reduced the symptoms and histopathological scores of UC mice.Additionally,it downregulated the inflammatory factors,interleukin(IL)-6 and IL-1 β,the immunoglobulins vascular cell adhesion molecule 1 and intercellular adhesion mole-cule 1,and metalloprotease matrix metallopeptidase 9.Moreover,it downregulated high mobility group box 1 protein.Furthermore,it inhibited the nuclear factor er-ythroid 2-related factor 2(Nrf2)/heme oxygenase-1(HO-1)pathway.Conclusions BTW improves the general condition,inflammatory indexes and oxidative stress level,and its mechanism may be related to inhib-iting the level of HMGB1 to regulate the Nrf-2/HO-1 signaling pathway and rescue intestinal barrier-related protein expression.

Objective:To investigate relationship between serum immunoglobulin(Ig),forkhead box protein P3(Foxp3)and therapeutic effect of nivolumab in patients with advanced non-small cell lung cancer(NSCLC).Methods:A total of 180 advanced NSCLC patients admitted to Hengshui People's Hospital between January 2020 and January 2024 were selected as NSCLC group,and 180 healthy individuals who underwent physical examinations during same period were selected as healthy group.Serum IgA,IgM,IgG and Foxp3 levels were measured,and differences in serum IgA,IgM,IgG and Foxp3 levels between two groups were compared,as well as their differences of levels in different clinical characteristics of advanced NSCLC patients.Advanced NSCLC patients were treated with nivolumab on basis of paclitaxel and carboplatin chemotherapy,and divided into treatment effective group(n=82)and treatment ineffective group(n=98)based on efficacy.Differences of serum IgG and Foxp3 levels between two groups were compared,and efficacy of serum IgG and Foxp3 in predicting therapeutic effect of nivolumab in advanced NSCLC patients was analyzed.Results:Serum IgG and Foxp3 levels in NSCLC group were higher than healthy group(P<0.05),and there was no statistically significant difference in serum IgA and IgM levels between two groups(P>0.05).Serum IgG and Foxp3 levels in TNM stage Ⅳ and poorly differentiated NSCLC patients were higher than stage Ⅲ NSCLC patients(P<0.05).TNM stage Ⅳ,proportion of low differentiation,and serum IgG and Foxp3 levels in ineffective group were higher than effective group(P<0.05).Logistic regression analysis showed that differentiation level,high IgG and high Foxp3 levels were risk factors for ineffective treatment with nivolumab in advanced NSCLC patients(P<0.05).Predictive efficacy of combination of serum IgG and Foxp3 in treatment of advanced NSCLC patients with nivolumab was superior to any single therapy,with an AUC of 0.978,sensitivity of 96.75%,and specificity of 92.13%.Conclusion:Elevated serum IgG and Foxp3 levels in patients with advanced NSCLC are risk factors for nivolumab treatment failure,and can be used as a reference index to predict therapeutic effect of nivolumab.

Personalized drug response prediction from molecular data is an important challenge in precision medicine for treating cancer.Computational methods have been widely explored and have become increasingly accurate in recent years.However,the clinical application of prediction methods is still in its infancy due to large discrepancies between preclinial models and patients.We present a novel disentangled synthesis transfer network(DiSyn)for drug response prediction specifically designed for transfer learning from preclinical models to clinical patients.DiSyn uses a domain separation network(DSN)to disentangle drug response related features,employs data synthesis technology to increase the sample size and iteratively trains for better feature disentanglement.DiSyn is pretrained on large-scale unlabeled cancer samples and validated by three datasets,The Cancer Genome Atlas(TCGA),Investigation of Serial Studies to Predict Your Therapeutic Response With Imaging And moLecular Analysis 2(I-SPY2)and Novartis Institutes for Biomedical Research Patient-Derived Xenograft Encyclopedia(NIBR PDXE),achieving competitive performance with the state-of-the-art methods on cancer patients and mice.Furthermore,the application of DiSyn to thousands of breast cancer patients show the heterogeneity in drug responses and demonstrate its potential value in biomarker discovery and drug combination prediction.

The endoplasmic reticulum is an important organelle responsible for the synthesis,folding and processing of proteins.When the endoplasmic reticulum protein folding ability is affect-ed,internal unfolded proteins or misfolded proteins accumulate in the endoplasmic reticulum accumulation,leading to endoplasmic reticulum structural dysfunction resulting in endoplasmic reticu-lum stress.Autophagy is the process by which cells selectively remove stress endoplasmic reticulum and error proteins.Under stress,the endoplasmic reticulum can maintain normal physiolog-ical functions through unfolded protein responses and autophagy.Postmenopausal osteoporosis is mainly due to an imbalance be-tween bone resorption by osteoclasts and bone formation by oste-oblasts.Endoplasmic reticulum stress and autophagy both modu-late bone cells status with consequences for bone homeostasis.This article provides a review of the progress of research on en-doplasmic reticulum stress and autophagy interaction in the path-ogenesis of postmenopausal osteoporosis.

OBJECTIVE To explore the relationship between levels of peripheral blood interleukin(IL)-6,IL-18,IL-1β,tumor necrosis factor(TNF-α),procalcitonin(PCT),C-reactive protein(CRP)and vascular cell adhesion molecule-1(VCAM-1)and disease condition and prognosis in children with Mycoplasma pneumoniae pneumonia(MPP),and to construct a prediction model.METHODS A total of 196 children with MPP admitted to Dazhou Central Hospital in Sichuan Province from Jan.2022 to Jan.2024 were selected as the MPP group and were divided into the mild group(n=124)and the severe group(n=72)according to the clinical pulmonary infection score(CPIS),and 200 healthy children who participated in physical examination in the hospital during the same period were selected as the healthy group.All 196 children with MPP received relevant treatments and were divided into a poor prognosis group(n=40)and a good prognosis group(n=156)according to their prognosis.The levels of peripheral blood IL-6,IL-18,IL-1β,TNF-α,PCT,CRP and VCAM-1 were measured in all the subjects,the risk factors affecting the disease condition and prognosis of children with MPP were analyzed,the prediction model was constructed,and the receiver operating characteristic(ROC)curve was drawn and the area under the curve(AUC)was calculated to evaluate the predictive effect of the constructed prediction model.RESULTS Peripheral blood IL-6,IL-18,IL-1β,TNF-α,PCT,CRP and VCAM-1 levels in the MPP group were higher than those in the healthy group(P＜0.05).The levels of IL-6,IL-18,IL-1β,TNF-α,PCT,CRP and VCAM-1 in peripheral blood were significantly higher in the severe group than those in the mild group(P＜0.05).IL-6(OR=1.203),IL-18(OR=1.072),IL-1β(OR=4.060),TNF-α(OR=1.264),PCT(OR=3.132),CRP(OR=1.546)and VCAM-1(OR=1.009)were risk factors for severe condition in MPP children(P＜0.05).The prediction model constructed for the devel-opment of severe illness in MPP children was as follows:Logit(P)=-67.522+0.185×IL-6+0.069×IL-18+1.401×IL-1β+0.234×TNF-α+1.142×PCT+0.436×CRP+0.009 ×VCAM-1.The AUC of the prediction model for predicting severe conditions in MPP children was 0.985.The levels of IL-6,IL-18,IL-1β,TNF-α,PCT,CRP and VCAM-1 in peripheral blood in the poor prognosis group were higher than those in the good prognosis group(P＜0.05).IL-6(OR=1.083,95％CI:1.024-1.145,P=0.005),TNF-α(OR=1.083,95％CI:1.002-1.172,P=0.046)and VCAM-1(OR=1.029,95％CI:1.015-1.044,P＜0.001)were risk factors for poor prognosis in MPP children.The prediction model established for poor prognosis in children with MPP was as follows:logit(P)=-31.557+0.080×IL-6+0.080×TNF-α+0.029×VCAM-1.The AUC of the prediction model for predicting poor prognosis in MPP children was 0.979.CONCLUSIONS The levels of IL-6,IL-18,IL-1β,TNF-α,PCT,CRP and VCAM-1 in pe-ripheral blood are closely related to the severity of illness in children with MPP.The prediction model constructed on the basis of the above indicators predicts the risk of severe disease in children with MPP,and the prediction model constructed on the basis of IL-6,TNF-α and VCAM-1 predicts the risk of poor prognosis in children with MPP.

This study was aimed at establishing a method of ultra-fast quantitative PCR for Brucella detection.We used an exogenous recombinant plasmid as the internal reference and targeted the T4SS secretion system,an important Brucella viru-lence factor,to design specific primers and probes.The sensitivity,specificity,and repeatability of this method were evaluated,and a standard curve was constructed.The coincidence rate of detection findings with this method versus quantitative PCR was determined.This method markedly decreased the detection time to only 10 minutes.The standard curve demonstrated a good linear relationship(Y=-3.410 7x+38.357,R2=0.998 5)with a low minimum detection limit of 10 copies/μL.The method exhibited good specificity and did not specifically amplify several common clinical bacteria other than Brucella.The de-tection of three concentrations of positive plasmids yielded coefficients of variation(CVs)of 0.20％to 0.91％,thus demonstra-ting the method's excellent repeatability.Furthermore,140 clinical samples were analyzed concurrently with the fluorescence PCR method,which yielded a 100％compliance rate and consistent results.Our findings indicated that the Brucella ultra-fast quantitative PCR was ultrafast;had high sensitivity,high specificity,and good specificity;and can be used for the clinical de-tection of Brucella and emergency investigation of epidemics.Therefore,this method is valuable for the early diagnosis of Bru-cella.
