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.

ObjectiveTo analyze the changes in the degree of coordination of China's major epidemic prevention and control efforts before and after the outbreak of the Corona Virus Disease 2019 (COVID-19), so as to explore the impact of epidemic prevention and control measures on coordination dynamics. MethodsA total of 3 864 policy documents related to epidemic prevention and control from January 2000 to December 2020 across 31 provinces (autonomous regions, and municipalities) in China were systematically collected. Contents specific to collaborative and cooperative efforts were extracted, and the extent of interdepartmental coordination were quantified to assess the effectiveness of epidemic prevention and control efforts. Wilcoxon signed-rank test was adopted to statistically analyze the differences between the indicators before and after the epidemic. ResultsThe average overall coordination level for major epidemic prevention and control in 31 provinces (autonomous regions, and municipalities) increased from 43.06% to 97.62%, and the average coordination levels in the eastern, central, and western China soared from 42.29%, 37.50%, and 47.46%, to 98.81%, 96.20%, and 97.46%, respectively, with statistically significant differences (all P<0.05). In terms of department categorization, coordination levels in the professional departments and the key support departments peaked at 100.00%, while other support departments rose to 95.43%, with an increase of 77.15%, 181.85%, and 139.89%, respectively, exhibiting noteworthy statistically significant differences (all P<0.001). ConclusionThe scope of coordination departments of China’s major epidemic prevention and control exists a remarkable surge following the COVID-19 outbreak, notable heightened coordination is particularly observed among the key support departments. Future endeavors should prioritize the roles played by diverse departments in epidemic prevention and control, enhancing both the clarity of departmental responsibilities and the effectiveness of interdepartmental coordination.

Objective:To observe any effect of combining visual deprivation training (VDT) with repeated low-frequency transcranial magnetic stimulation (rTMS) in the treatment of lower limb motor dysfunction among stroke survivors.Methods:Fifty stroke survivors were randomly assigned to either a control group or an experimental group ( n=25 each). In addition to routine rehabilitation treatment, the control group received rTMS targeting the primary motor cortex (M1, lower limb representation area) of the unaffected hemisphere, while the experimental group also received VDT. Before and after 4 weeks of the treatments, everyone′s lower limb motor function, balance, gait and ability in the activities of daily living were evaluated using the Fugl-Meyer lower extremity assessment (FMA-LE), the root mean square (RMS) values generated through surface electromyography of the affected tibialis anterior muscle, the Berg Balance Scale (BBS), the Timed Up and Go Test (TUGT), the Tinetti Gait Assessment (TGA), and the modified Barthel Index (MBI). Results:After the treatment, both groups showed significant improvements in their average FMA-LE, BBS, TUGT, TGA and MBI results, as well as in the RMS values of the affected tibialis anterior muscle. The experimental group showed significantly greater improvement compared to the control group.Conclusions:The combination of VDT and low-frequency rTMS can effectively improve the lower limb motor function, balance and gait of stroke survivors. It is more effective than rTMS alone. The combined therapy is worthy of clinical application and promotion.

Objective To analyze the application effect of acetaminophen preemptive analgesia combined with intercostal nerve block in thoracoscopic lobectomy.Methods A total of 120 patients with lung cancer who underwent thoracoscopic lobectomy admitted to Lu'an Traditional Chinese Medicine Hospital from January 2021 to September 2023 were selected as the study objects,and they were divided into the control group and the observation group according to random number table method,with 60 cases in each group.Patients in the control group were given acetaminophen preemptive analgesia before anesthesia induction,while patients in the observation group were given intercostal nerve block on the basis of the control group.The visual analogue scale(VAS)score,Ramsay sedation score,serum β-endorphin level and prostaglandin E2 level 3,12,24 and 48 hours after operation of patients in the two groups were compared.The stress response indexes such as norepinephrine(NE),epinephrine(E)and serum cortisol(Cor),as well as immune function indexes such as CD3+,CD4+and CD4+/CD8+before anesthesia induction and after extubation of patients in the two groups were compared.The incidence of adverse reactions after extubation of patients in the two groups were compared.Results The VAS scores of patients after surgery in the two groups gradually increased with time,and the Ramsay sedation scores gradually decreased with time.The VAS scores of patients in the observation group were lower than those in the control group at each postoperative time point,and the Ramsay sedation scores were higher than those in the control group,with statistically significant differences(P<0.05).The levels of serum β-endorphin and prostaglandin E2 of patients after surgery in the two groups gradually decreased with time.The levels of serum β-endorphin of patients at each postoperative time point in the observation group were higher than those in the control group,and the levels of prostaglandin E2 of patients at each postoperative time point in the observation group were lower than those in the control group,with statistically significant differences(P<0.05).The levels of NE,E,and Cor after extubation of patients in the two groups were significantly decreased(P<0.05),and those in the observation group were lower than those in the control group(P<0.05).The levels of CD3+,CD4+,and CD4+/CD8+after extubation of patients in the two groups were significantly decreased(P<0.05),and those in the observation group were higher than those in the control group(P<0.05).The total incidence of adverse reactions in the observation group was lower than that in the control group,with statistically significant difference(P<0.05).Conclusion The application of acetaminophen preemptive analgesia combined with intercostal nerve block in thoracoscopic lobectomy has good analgesic and sedative effects on patients,which is helpful to improve patients'immune function and reduce postoperative adverse reactions.

A subset of patients with multiple myeloma(MM)present with reduced serum vitamin B12 levels at initial diagnosis;however,its clinical significance and underlying mechanisms remain unclear.Vitamin B12 plays a crucial role in hematopoiesis and immune regulation.This study aims to elucidate its association with extramedullary diseases,immune function,and prognosis in MM patients.A retrospec-tive analysis was conducted of 92 newly diagnosed MM patients,who received treatment at the Second Af-filiated Hospital of Soochow University between January 2020 and December 2023.Patients were classi-fied into a low vitamin B12 group(n=37)and a normal vitamin B12 group(n=55)based on their ser-um vitamin B12 levels.The findings revealed that the incidence of extramedullary infiltration was signifi-cantly higher in the low vitamin B12 group than in the normal group(26.5％vs.17.0％,P=0.031).Survival analysis demonstrated that patients with low vitamin B12 levels had significantly shorter overall survival(OS)and progression-free survival(PFS)(OS:P=0.0123;PFS:P=0.0136).Additionally,these patients showed a decreasing trend in peripheral blood total T cell,CD4+T cell,and CD8+T cell counts,with serum vitamin B12 levels showing a significant positive correlation with the total T cell count(R=0.2717,P=0.0135)and CD4+T cell count(R=0.2175,P=0.0497).In conclusion,reduced serum vitamin B12 levels at initial diagnosis are significantly associated with poor prognosis in MM pa-tients and may serve as a potential prognostic biomarker.Furthermore,vitamin B12 deficiency may con-tribute to immune dysfunction,particularly impaired T cell immunity,and a higher incidence of extr-amedullary diseases.

Objective To explore the mechanism of electroacupuncture in alleviating hyperlipidemia in a rat model by modulating mammalian target of rapamycin complex 1(mTORC1)-mediated lipophagy in hepatocytes.Methods A total of 30 SD rats were randomly divided into blank(n=6)and modeling groups(n=24)using the random number table method.A hyperlipidemic rat model was established by feeding rats a high-fat diet(feeding for 8 weeks).After successful modeling,the modeling group was randomly divided into the model,electroacupuncture,mTORC1 inhibitor,and electroacupuncture+mTORC1 agonist groups,with six rats in each group.Except for the blank group,all other rats were fed with high fat diet.Rats in the electroacupuncture and electroacupuncture+mTORC1 agonist groups received electroacupuncture intervention at bilateral"Fenglong"(ST40)acupoints(dilatational wave 2 Hz/100 Hz,current intensity 1 mA)for 30 min once daily.Rats in the mTORC1 inhibitor group received intraperitoneal injections of the mTORC1 inhibitor,rapamycin(2 mg/kg),once daily.Rats in the electroacupuncture+mTORC1 agonist group received intraperitoneal injections of the mTORC1 agonist MHY1485(10 mg/kg)once daily.The interventions were administered for five consecutive days per week for 4 weeks.Upon completion of the intervention,the following analyses were performed:serum contents of total cholesterol(TC),triglycerides(TAG),low-density lipoprotein cholesterol(LDL-C),high-density lipoprotein cholesterol(HDL-C),free fatty acids(FFA),alanine aminotransferase(ALT),and aspartate aminotransferase(AST)were measured using a fully automated biochemical analyzer.Hepatic histopathological changes and lipid deposition were observed using hematoxylin-eosin and oil red O staining.The liver condition was observed and the liver index was calculated.Hepatic TC and TAG levels were measured using an enzyme-linked immunosorbent assay.The ultrastructure of the liver tissue was observed using transmission electron microscopy,and the mean fluorescence intensity of perilipin 2(PLIN2)and microtubule-associated protein 1 light chain 3(LC3)-Ⅱ in the liver tissue was detected using immunofluorescence.Protein expression of LC3-Ⅱ/LC3-Ⅰ,phosphorylated mammalian target of rapamycin(p-mTOR)/mTOR,and mTORC1 in liver tissue was detected using Western blotting.Results Compared to the blank group,the model group rats showed increased serum TC,TAG,LDL-C,ALT,AST,and FFA levels,along with decreased HDL-C levels(P<0.05).The liver index and hepatic TC and TAG levels were also elevated(P<0.05).Histological examination of liver tissue revealed substantial lipid accumulation,numerous lipid droplets within hepatocytes,abnormal mitochondrial morphology,and scarce autophagic vacuole.The mean fluorescence intensity of PLIN2 increased,whereas that of LC3-Ⅱ decreased(P<0.05).Additionally,the LC3-Ⅱ/LC3-Ⅰ ratio was reduced,whereas the p-mTOR/mTOR ratio and mTORC1 protein expression were increased(P<0.05).Compared to the model group,rats in the mTORC1 inhibitor and electroacupuncture groups exhibited decreased serum TC,TAG,LDL-C,ALT,AST,and FFA levels(P<0.05),along with a reduced liver index and hepatic TC and TAG levels(P<0.05).Histological examination showed markedly attenuated lipid accumulation and visible autophagic vacuole in the hepatocytes.The mean fluorescence intensity of PLIN2 decreased,whereas that of LC3-Ⅱ increased(P<0.05).Moreover,the LC3-Ⅱ/LC3-Ⅰ ratio increased,whereas the p-mTOR/mTOR ratio and mTORC1 protein expression decreased(P<0.05).In comparison with both the electroacupuncture and mTORC1 inhibitor groups,the electroacupuncture+mTORC1 agonist group demonstrated increased serum TAG,TC,LDL-C,ALT,AST,and FFA levels(P<0.05)as well as elevated liver index and hepatic TC and TAG levels(P<0.05).Liver tissues exhibited aggravated lipid deposition and absence of autophagic vacuole in liver cells.The mean fluorescence intensity of PLIN2 was enhanced,whereas that of LC3-Ⅱ was reduced(P<0.05).Furthermore,the LC3-Ⅱ/LC3-Ⅰ ratio decreased,and the p-mTOR/mTOR ratio and mTORC1 protein expression increased(P<0.05).Conclusion Electroacupuncture at"Fenglong"(ST40)may improve blood lipid levels in hyperlipidemic rats by inhibiting mTORC1 and promoting hepatocyte lipophagy.

Chronic stress triggers the imbalance of the homeostasis of the tumor immune microenvironment(TIME),which is a key factor driving the development of lung cancer.Based on the mapping relationship between the concept of"spirit"in traditional Chinese medicine and chronic stress,and between"qi"and"immunity",it is believed that the cross-linking mechanism of"chronic stress-TIME-lung cancer"aligns with the understanding of traditional Chinese medicine of disease as involving the interplay between the"body,qi and spirit".The disorganization of"spirit"and"qi"is not only the root of the change of the"form",but also the key to prevent and control it.The treatment principle of synergizing to improve the chronic stress of"regulating the spirit"and remodeling the TIME of"invigorating the qi"is further proposed,which emphasizes on grasping the core pathogenesis of lung cancer at each stage of its evolution in order to administer medicines,drawing on the clinical experience and pharmacological research results in order to accurately hit the target,and combining special therapies like acupuncture,Chinese kungfu,sound therapy to treat the change of"shape"by modulating neuro-endocrine-immune network homeostasis,so as to provide new ideas and accessible solutions for the comprehensive prevention and treatment system of lung cancer.

Objective To explore the effect of visual deprivation training combined with proprioceptive training on balance function of hemiplegic patients after stroke.Methods A total of 80 stroke patients with hemiplegia in Jiangsu Shengze Hospital were selected from May,2022 to March,2024,and randomly divided into control group(n=20),proprioceptive training group(n=20),visual de-privation group(n=20)and combined group(n=20).All the groups received routine rehabilitation training,while the proprioceptive training group added proprioceptive training,the visual deprivation group added balance training under visual deprivation,and the combined group added visual deprivation training and proprioceptive training,for four weeks.They were assessed with ProKin Balance Test and Training System,Berg Balance Scale(BBS),10-metre walking test(10MWT),Fugl-Meyer Assessment-Lower Extremities(FMA-LE)and Functional Gait Assessment(FGA)before and after treatment.Results The intra-group effect(F>96.618,P<0.001)and interaction effect(F>5.444,P<0.01)were significant in mean longitudinal velocity and mean horizontal velocity.The intra-group effect(F>177.671,P<0.001),inter-group effect(F>3.761,P<0.05)and interaction effect(F>7.555,P<0.001)were significant in movement el-lipse area and movement length both with eyes open and closed.The intra-group effect(F>221.902,P<0.001)and interaction effect(F>7.586,P<0.001)were significant in the time of 10MWT,and the scores of BBS,FMA-LE and FGA;and the inter-group effect were significant in FGA score(F=5.258,P<0.01).Post Hoc test showed that all the indicators were better in the combined group and the visual deprivation group than in the con-trol group(P<0.05);as well as in the proprioceptive training group than in the control group(P<0.05)except mean longitudinal velocity with eyes open,mean horizontal velocity with eyes closed,and movement length with eyes open;while all the indicators were better in the combined group than both in the visual deprivation group and the proprioceptive training group(P<0.05);there was no significant difference between the visual depriva-tion group and the proprioceptive training group for all the indicators(P>0.05).Conclusion Both visual deprivation training and proprioceptive training can improve balance,lower limb motor function and walking of hemiplegic stroke patients,and the combination is more effective.
