Based on LI Gao's Academic Thought， focusing on the process of qi transformation and taking the regulation and restoration of metabolism and immunity as the entry point， a "source-pivot-convergence" diagnostic and therapeutic model for malignant tumors is constructed. In this model， spleen and stomach internal injury is the source of malignant tumor occurrence， while the disorder of ascending and descending is the pivot of the disease development， and the generation of yin fire is the convergence of malignant tumor progression. Based on this， the three major therapeutic methods of clearing the source， harmonizing the pivot， and resolving the convergence are established. To fortify spleen and boost qi， consolidate the root and clear the source， modified Buzhong Yiqi Decoction（补中益气汤）can be used. To raise the clear and direct the turbid downward， regulate qi and harmonize the pivot， modified Shengyang Yiwei Decoction （升阳益胃汤） is suggested. To restore balance and promote circulation， disperse accumulation and resolve convergence， modified Shengyang Sanhuo Decoction （升阳散火汤） is selected. In clinical practice， these formulas can be used in combination according to the complexity of the pathogenesis， and further adapted with prescriptions for promoting dispersion and penetrating pathogenic factors， resolving phlegm and promoting circulation， activating blood and eliminating concretions， which can provide a reference for the prevention and treatment of tumor diseases.

BACKGROUND:Deep muscle stimulation has the effects of releasing muscle adhesion,relieving muscle spasm,improving and restoring muscle compliance and elasticity.Electromyographic biofeedback therapy can promote nerve recovery and improve lower limb motor function and gait. OBJECTIVE:To observe the effect of the effect of deep muscle stimulation combined with electromyographic biofeedback therapy on the spasm of the triceps surae and gait changes after stroke by using a digital muscle detector and three-dimensional gait analysis system. METHODS:A total of 72 patients who met the inclusion criteria were selected from the Rehabilitation Department of the First Affiliated Hospital of Guangdong Pharmaceutical University from October 2020 to October 2023.And they were enrolled and randomly divided into two groups(n=36 per group):a control group and a combined group.The control group received routine rehabilitation therapies,electromyographic biofeedback and pseudo deep muscle stimulation,while the combined group received true deep muscle stimulation treatment on the basis of the control group,five times per week,for 4 consecutive weeks.The oscillation frequency and dynamic stiffness of the affected gastrocnemius muscle,active range of motion of the ankle dorsiflexion muscle,electromyographic signal of the tibialis anterior muscle,Fugl-Meyer assessment of the lower limbs,and three-dimensional gait analysis parameters were statistically analyzed before and after treatment in two groups. RESULTS AND CONCLUSION:After treatment,oscillation frequency and dynamic stiffness values of the inner and outer sides of the affected gastrocnemius muscle in both groups of patients were significantly reduced compared with before treatment(P<0.05),and the combined group showed a more significant decrease compared with the control group(P<0.05).The active range of motion of the ankle dorsiflexion muscle,electromyographic signal of the tibialis anterior muscle,and Fugl-Meyer scores after treatment were significantly increased or improved compared with before treatment(P<0.05),while the combined group showed a more significant increase or improvement compared with the control group(P<0.05).In terms of gait parameters,the walking speed,frequency,and stride in both groups of patients were significantly increased compared with before treatment(P<0.05),while the combined group showed a more significant increase compared with the control group(P<0.05).The percentage time of support phase on the healthy side was shortened compared with before treatment(P<0.05),while the combined group showed a more significant decrease compared with the control group(P<0.05).In addition,there was no significant difference between the two groups except for the percentage of healthy side support(P>0.05).To conclude,the combination of deep muscle stimulation and electromyographic biofeedback can effectively alleviate triceps spasm in the short term after stroke,improve ankle dorsiflexion function,enhance lower limb motor function,and improve gait.The treatment effect is significant and worthy of clinical promotion and application.

Mitophagy,a special form of selective autophagy,plays a significant role in the pathogenesis of atherosclerosis by regulating cellular lipid metabolism,inflammation,and oxidative stress.However,its regulatory mech-anism is complex and has not been fully elucidated.Notably,many drugs and herbal ingredients exhibit anti-atherosclerot-ic effects by modulating mitophagy in macrophages,vascular endothelial cells,and vascular smooth muscle cells,offering potential new avenues for the prevention and treatment of atherosclerosis.In this article,we review the role of mitophagy in regulating cellular functions and the progression of atherosclerosis,as well as summarize potential therapeutic drugs that may contribute to anti-atherosclerosis by modulating mitophagy.Our aim is to provide a new literature basis for further ex-ploration of the role of mitophagy in atherosclerosis.

Purpose The study aimed to analyze the relationship between MET gene variants and clinicopathologi-cal features in patients with non-small cell lung cancer(NSCLC).Methods Next-generation sequencing technology was used to detect MET gene variants in NSCLC specimens.The association between MET gene variant status and clini-copathological features was then analyzed.Results Among 1 633 cases of NSCLC,the overall MET mutation rate was 4.53％(74/1 633).Variants were mainly observed in male patients,never-smokers,those older than 60 years,ade-nocarcinoma histology,and patients with TNM stage Ⅲ+Ⅳ disease(P＜0.05).MET gene variant status showed no significant assocication with patient age,sex,smoking history,or pathological subtype(P＞0.05),but was statistical-ly correlated with clinical stage and presence of distant metastasis(P＜0.05).The two major variant types were MET exon 14 skipping and MET amplification,which together accounted for 71.62％of all variants.In addition,MET am-plification was positively correlated with EGFR(P=0.003,rs=0.340)and TP53 mutations(P=0.002,rs=0.362),but showed no correlation with KRAS or ALK gene mutations.In contrast,MET exon 14 skipping was nega-tively correlated with EGFR gene mutations(P＜0.001,rs=-0.409),and showed no significant correlation with KRAS,ALK,or TP53 mutations.Conclusion Different types of MET gene variants(amplification,exon 14 skip-ping,fusion,and others)are significantly associated with clinical advanced clinical stage and distant metastasis in NSCLC,but are independent of patient age,sex,smoking history,and pathological subtype.MET amplification fre-quently co-occur with EGFR and TP53 co-mutations.

Objective To investigate the neuroprotective effect of Dendrobium nobile Lindl(DNL)extract in a Caenorhabditis elegans(C.elegans)model of Parkinson's disease(PD).Methods C.elegans NL5901 and 6-hydroxydopamine(6-OHDA)induced N2,BZ555,PD4521,and CB7272 C.elegans strains were treated with DNL 7.5,15,and 30 mg/L.The survival rate,basal slowing response rate,α-synuclein(α-syn)aggregation,dopaminergic neurons(DNs),mitochondrial distribution density of body wall muscle cells,and protein levels in the membrane were observed.In addition,reactive oxygen species(ROS),superoxide dismutase(SOD)and glutathione(GSH)in 6-OHDA induced N2 was detected to explore the effect of DNL on the antioxidative stress ability of PD C.elegans models.Results Compared with that in the model group,the DN fluorescence intensity was significantly increased in nematodes treated with DNL and levodopa(L-DOPA)(P＜0.05,P＜0.0001),α-syn aggregation was significantly decreased(P＜0.05,P＜0.001,P＜0.0001),the basal slowing rate(P＜0.05,P＜0.01,P＜0.001),mitochondrial density(P＜0.05,P＜0.01,P＜0.001),mitochondrial intima protein content(P＜0.05,P＜0.001,P＜0.0001),SOD content(P＜0.05),and GSH content were all increased.The ROS content was reduced in nematodes(P＜0.01).The lifespans of N2 wild-type and PD C.elegans models were prolonged after DNL treatment(P＜0.05,P＜0.01,P＜0.001).Conclusions DNL can effectively improve motor paralysis in a C.elegans PD model,improve DN degradation,inhibit α-syn aggregation and neuronal damage,increase the antioxidative stress ability,and slow the aging process in C.elegans.

Objective To explore the mediating role of intolerance of uncertainty(IU)and moderating role of the negative emotion differentiation in the influence of perceived stress on anxiety among college students from a cognitive perspective.Methods A total of 271 participants were surveyed using the perceived stress scale,intolerance of uncertainty scale,depression anxiety and stress scale(Chinese version),and the test on negative emotional differentiation.SPSS 22.0 was used to perform descriptive statistics and correlation analyses and to test the moderated mediation model.Results Perceived stress affected anxiety and IU played a mediating role-perceived stress could affect anxiety through influencing IU.At the same time,the influence of IU on anxiety could be adjusted through the negative emotion differentiation.The higher the degree of negative emotion differentiation,the lower the degree of anxiety increase(β=0.17,t=5.70,P＜0.01).Conclusion It may be effective to develop training programs to reduce anxiety by regulating perceived stress,increasing acceptance of uncertainty,and improving the negative emotion differentiation,which can help individuals reduce anxiety by perceiving and adjusting anxiety-related emotional or cognitive factors in a timely manner.

Objective To investigate the predictive value of heparin-binding protein(HBP)in Kawasaki disease complicated with bacterial infection.Methods A total of 148 children with Kawasaki disease in this hospital from April 2021 to June 2022 were selected as Kawasaki disease group.According to the results of pathogen detection during hospitalization,the children were divided into three subgroups:Mycoplasma pneu-moniae group(36 cases),bacteria group(19 cases),and non-infection group(93 cases).In addition,35 chil-dren with fever and upper respiratory tract infection were randomly selected as the case control group.HBP and other inflammatory markers[white blood cell count(WBC),neutrophil percentage(NE％),procalcitonin(PCT),C reactive protein(CRP),interleukin-6(IL-6)]in each group were detected and analyzed.Receiver operating characteristic(ROC)curve was used to analyze the predictive value of HBP and PCT for bacterial infection in children with Kawasaki disease.Results The levels of HBP,WBC,NE％,CRP and IL-6 in the Ka-wasaki disease group were significantly higher than those in the case control group(P＜0.05),while there was no significant difference in PCT level between the two groups(P＞0.05).The levels of HBP,WBC,NE％,PCT,CRP and IL-6 in children with Kawasaki disease after treatment were significantly lower than those at admission(P＜0.05).The levels of HBP and PCT in the bacterial group were higher than those in the Mycoplasma pneumoniae group and the non-infection group,and the differences were statistically signifi-cant(P＜0.05),while there were no statistically significant differences in WBC,NE％,CRP and IL-6 levels a-mong the three groups(P＞0.05).ROC curve results showed that the area under the curve(AUC)and 95％CI of HBP for predicting bacterial infection in children with Kawasaki disease was 0.77(0.68-0.86),when HBP was 499.65 ng/mL,the sensitivity and specificity were 84.2％and 66.7％,respectively.When PCT was 0.85 ng/mL,the AUC(95％CI)for predicting bacterial infection in children with Kawasaki disease was 0.65(0.52-0.78),and the sensitivity and specificity were 63.2％and 65.9％,respectively.Conclusion HBP is associated with Kawasaki disease,and it has certain predictive value for Kawasaki disease complicated with bacterial infection.

Objective:To formulate a community teacher standard for the training of general practitioner program (direction in hospice care).Methods:This was a qualitative study. Twenty-nine experts in general practice and hospice care from various teaching hospitals and community health service centers were invited to participate in two rounds of Delphi consultation from April to August 2022. Based on the results of the consultation, a standard for community faculty training in comprehensive care and end-of-life care for general practitioners was formulated, and the weight coefficients of the indicators were calculated.Results:Of the 29 experts, 11 (37.9%) were male, their age was (52.9±8.9) years, and their working life was (17.0±7.2) years. In the two rounds of expert consultation, the expert positive coefficient was 100.0% (29/29) and 96.6% (28/29), the expert authority coefficient was 0.789 and 0.851, and the expert opinion coordination coefficient W of the importance of all indicators was 0.124 and 0.131, respectively ( χ2=123.01, 131.71, P<0.05). Finally, a set of community-based teacher standard for general practitioner specialty training (direction in hospice care) was established, which consisted of 4 first-level indicators and 30 second-level indicators. The four first-level indicators were basic literacy, clinical qualification and ability, teaching qualification and ability, and scientific research ability, all with the weight coefficients of 0.254, 0.254, 0.252 and 0.240, respectively. Conclusion:The standard of teachers in the community base of general practitioner specialty training (direction in hospice care) established in this study is more scientific, which is conducive to the comprehensive evaluation of teachers in the community training base.
