Chronic obstructive pulmonary disease （COPD）， as a chronic respiratory disease that can be prevented and intervened but cannot be completely cured， has increasing incidence and mortality rates year by year， often complicated by one or more comorbidities. However， there is currently no specific treatment available. Therefore， the healthcare issues related to COPD are urgent and prominent. Traditional Chinese medicine （TCM） delays the progression of COPD through multiple mechanisms， pathways， and targets. As a result， exploring the pathogenesis of COPD and identifying TCM treatment approaches and effective prescriptions are key issues that urgently need to be addressed in clinical practice. In TCM， COPD is categorized into syndromes such as "cough"， "asthma"， and "lung distension". It is believed that the deficiency in the origin runs through the entire disease. When external pathogens invade， Qi becomes disordered， and phlegm and blood stasis begin to accumulate， leading to an excess condition in the manifestation. Modern medicine research on the pathogenesis of COPD mainly involves aspects such as inflammatory response， oxidative stress， autophagy imbalance， and aging. Studies have found that Chinese medicine monomers， single herbs， and compound prescriptions can improve COPD by inhibiting inflammation， reducing oxidative damage， correcting autophagy， and delaying aging. However， there is no study that intuitively organizes the various pathogenesis mechanisms of COPD and their interrelationships. At the same time， research on the therapeutic effects of TCM on COPD primarily focuses on exploring a single mechanism or pathway， without integrating multiple mechanisms， pathways， and targets. Additionally， there are very few studies that summarize the corresponding relationships between the various pathogenesis mechanisms of COPD and the regulatory effects and signaling pathways of Chinese medicine. This study， for the first time， combines the latest literature in China and abroad to explain the various pathogenesis mechanisms of COPD and their interrelationships using a combination of graphs， text， and tables. It also outlines the signaling pathways， targets， and mechanisms of Chinese medicine monomers， single herbs， and compound prescriptions in regulating COPD， in order to provide new ideas and strategies for the in-depth research and systematic treatment of COPD with TCM.

ObjectiveMicrotube associated protein-2 （MAP-2）， alpha-tubulin （α-tubulin）， and synaptophysin （SYP） are important proteins in neuronal signal communication. This paper observed the effects of modified Zhigancao Tang on the expression of serum α-Synuclein （α-Syn） and its oligomers， MAP-2， α-tubulin， and SYP of patients with liver and kidney deficiency of Parkinson's disease （PD）， analyzed their correlation， and evaluated the therapeutic effect of modified Zhigancao Tang in patients with liver and kidney deficiency of PD based on α-Syn transmission pathway mediated by neuronal communication in vivo. MethodsA total of 60 patients with PD who met the inclusion criteria were randomly divided into a treatment group （30 cases） and a control group （30 cases）. Both groups were treated on the basis of PD medicine， and the treatment group was treated with modified Zhigancao Tang. Both groups were treated for 12 weeks. The changes in UPDRS score， TCM syndrome score， and expression of serum α-Syn and its oligomers， MAP-2， α-tubulin， and SYP were observed before and after 12 weeks of treatment in each group. The correlation between the above-mentioned serum biological indexes and the levels of serum α-Syn and its oligomers was analyzed. ResultsAfter treatment， the TCM syndrome score， UPDRS score， UPDRS-Ⅱ score， and UPDRS-Ⅲ score of the treatment group were significantly decreased （P<0.05， P<0.01）. The UPDRS score， UPDRS-Ⅱ score， and UPDRS-Ⅲ scores in the treatment group were significantly decreased compared with those in the control group after treatment （P<0.05）. After treatment， the total effective rate of the control group was 63.3% （19/30）， and that of the treatment group was 86.7% （26/30）. The clinical effect of the observation group was better than the control group （Z=-2.03， P<0.05）. The total effective rate of the observation group was better than that of the control group， and the difference was statistically significant （χ²=5.136， P<0.05）. After treatment， the oligomer level of serum α-Syn and MAP-2 level in the treatment group were significantly decreased （P<0.05， P<0.01）. The levels of serum α-Syn and its oligomers， as well as α-tubulin in the treatment group， were significantly decreased compared with those in the control group after treatment （P<0.05， P<0.01）. Serum α-Syn was correlated with serum MAP-2 and α-Syn oligomer in patients with PD （P<0.05， P<0.01） but not correlated with serum SYP . Serum α-Syn oligomers of patients with PD were correlated with serum MAP-2 and α-tubulin （P<0.05， P<0.01） but not correlated with serum SYP level. Serum SYP of patients with PD was correlated with serum MAP-2 （P<0.05）. ConclusionModified Zhigancao Tang has a therapeutic effect on patients with liver and kidney deficiency of PD by inhibiting the production of α-Syn oligomers and intervening α-Syn microtubule transport pathway in vivo.

Objective:To establish a set of artificial intelligence (AI) verification rules for blood routine analysis.Methods:Blood routine analysis data of 18 474 hospitalized patients from the First Hospital of Jilin University during August 1st to 31st, 2019, were collected as training group for establishment of the AI verification rules,and the corresponding patient age, microscopic examination results, and clinical diagnosis information were collected. 92 laboratory parameters, including blood analysis report parameters, research parameters and alarm information, were used as candidate conditions for AI audit rules; manual verification combining microscopy was considered as standard, marked whether it was passed or blocked. Using decision tree algorithm, AI audit rules are initially established through high-intensity, multi-round and five-fold cross-validation and AI verification rules were optimized by setting important mandatory cases. The performance of AI verification rules was evaluated by comparing the false negative rate, precision rate, recall rate, F1 score, and pass rate with that of the current autoverification rules using Chi-square test. Another cohort of blood routine analysis data of 12 475 hospitalized patients in the First Hospital of Jilin University during November 1sr to 31st, 2023, were collected as validation group for validation of AI verification rules, which underwent simulated verification via the preliminary AI rules, thus performance of AI rules were analyzed by the above indicators. Results:AI verification rules consist of 15 rules and 17 parameters and do distinguish numeric and morphological abnormalities. Compared with auto-verification rules, the true positive rate, the false positive rate, the true negative rate, the false negative rate, the pass rate, the accuracy, the precision rate, the recall rate and F1 score of AI rules in training group were 22.7%, 1.6%, 74.5%, 1.3%, 75.7%, 97.2%, 93.5%, 94.7%, 94.1, respectively.All of them were better than auto-verification rules, and the difference was statistically significant ( P<0.001), and with no important case missed. In validation group, the true positive rate, the false positive rate, the true negative rate, the false negative rate, the pass rate, the accuracy, the precision rate, the recall rate and F1 score were 19.2%, 8.2%, 70.1%, 2.5%, 72.6%, 89.2%, 70.0%, 88.3%, 78.1, respectively, Compared with the auto-verification rules, The false negative rate was lower, the false positive rate and the recall rate were slightly higher, and the difference was statistically significant ( P<0.001). Conclusion:A set of the AI verification rules are established and verified by using decision tree algorithm of machine learning, which can identify, intercept and prompt abnormal results stably, and is moresimple, highly efficient and more accurate in the report of blood analysis test results compared with auto-vefication.

Objective:To evaluate the effects of berberine on necroptosis of non-alcoholic fatty liver disease in mice and its relationship with adenosine monophosphate-activated protein kinase(AMPK)/ signal transducer and activator of transcription 6(STAT6) pathway.Methods:Twenty-five 8-week-old male C57BL/6N mice were divided into control group, steatotic liver group, berberine treatment group(200 mg·kg -1·d -1), AMPK inhibitor Compound C treatment group(0.2 mg·kg -1·d -1), and STAT6 inhibitor AS1517499 treatment group(10 mg·kg -1·d -1). After 12 weeks of intervention, the mice and liver tissue were weighed, and serum aspartate aminotransferase(AST), alanine aminotransferase(ALT), triglyceride, tumor necrosis factor-α(TNF-α), interleukin-1β(IL-1β) as well as liver malondialdehyde and superoxide dismutase were measured; liver tissue HE, Masson, and oil red O staining were performed. Western blotting was used to detect the expressions of necroptosis related proteins[receptor interaction protein kinase 3(RIPK3), phosphorylated(p-) mixed lineage kinase domain-like(MLKL)], AMPK, p-AMPK, and p-STAT6. Results:Compared with control group, the steatotic liver group had higher quality of liver and liver index, and higher levels of serum AST, ALT, triglyceride, TNF-α, IL-1β, and oxidative stress( P<0.05); Liver tissue was full of cavity changes and inflammatory cell infiltration, widely distributed red lipid droplets and obvious blue fiber dyeing; The expressions of RIPK3 and p-MLKL were up-regulated ( P<0.05), but the levels of p-AMPK and p-STAT6 were relatively reduced ( P<0.05). Compared with the steatotic liver group, berberine intervention decreased liver quality and liver index, improved liver function, reduced blood lipid levels, pro-inflammatory factor expression and oxidative stress level, and significantly alleviated the degree of liver steatosis and fibrosis, the levels of RIPK3 and p-MLKL ( P<0.05), while the expressions of p-AMPK and p-STAT6 were increased significantly ( P<0.05). As compared with the berberine treatment, AMPK and STAT6 inhibitor treatment could offset the protective effect of berberine on steatotic liver, moreover, the expressions of RIPK3 and p-MLKL were increased ( P<0.05). There was no statistical difference in AMPK total protein content among the five groups ( P>0.05). Conclusion:Berberine can activate AMPK/STAT6 pathway to inhibit the necroptosis of hepatocyte, thus plays a protective role on non-alcoholic fatty liver disease in mice.

Objective:To investigate the clinical efficacy of autologous peripheral blood hematopoietic stem cell transplantation (HSCT) in treatment of lymphoma.Methods:The clinical data of 41 lymphoma patients undergoing autologous peripheral blood HSCT at the Affiliated Hospital of Jining Medical University between January 2014 to December 2020 were retrospectively analyzed. There were 6 cases of Hodgkin lymphoma and 35 cases of non-Hodgkin lymphoma. The mobilization regimens included chemotherapy drugs + granulocyte colony-stimulating factor (G-CSF) + thrombopoietin (TPO) or chemotherapy drugs + G-CSF. The pre-conditioning schemes before transplantation were listed as follows: BEAM (mustine + cytarabine + etoposide + melphalan) regimen + decitabine in 26 patients, BEAM regimen in 12 patients, BEAM regimen + chidamide in 3 patients. The progression-free survival (PFS), overall survival (OS), related complications, prognoses after transplantation were observed. The effects of clinical staging, B symptom,International Prognostic Score Index (IPI), extranodal involved sites, hemoglobin (Hb), lactic dehydrogenase (LDH), β 2-microglobulin (β 2-MG), transplantation regimen and the status before transplantation on PFS and OS after transplantation were evaluated. Results:Among 41 patients, 37 patients (90.24%) achieved complete remission (CR), 2 patients (4.88%) achieved partial remission (PR) and 2 patients loss assessment data (4.88%) before autologous peripheral blood HSCT. The median karyocyte count was 12.74×10 8 /kg [(3.91-22.68)×10 8/kg] in 24 patients with the complete data of stem cell collection, the median CD34 positive cell count was 6.74×10 6/kg [(0.91-50.47)×10 6/kg]. All 41 patients had hematologic reconstruction. The median time of platelet implantation was 11 d (7-32 d) and the median time of granulocyte implantation was 9 d (8-16 d). All patients achieved CR after transplantation and no one case had transplantation-related death. By the end of follow-up, 33 cases (80.49%) had no progression of disease, 8 cases (19.51%) died. The OS rates of 12-month, 24-month and 72-month were 93.4%, 85.3% and 60.9%, respectively after transplantation. The PFS rates of 12-month, 24-month and 72 month were 93.3%, 84.0% and 84.0%, respectively. Median PFS and OS had not been reached. There were no statistically significant differences in the PFS and OS of patients with different gender, clinical staging, B symptom, IPI score, extranodal involved sites, Hb, LDH, β 2-MG and the status before transplantation(all P > 0.05) . The PFS and OS of patients receiving BEAM regimen + decitabine were better than those of patients receiving BEAM regimen alone (all P < 0.05). Conclusions:Autologous peripheral blood HSCT is effective in treatment of lymphoma. Moreover, BEAM regimen + dicitabine preconditioning regimen can achieve longer survival time compared with BEAM regimen alone.

Objective:To evaluate the role of silencing information regulator 1 (SIRT1)/nuclear factors E2-related factor2 (Nrf2) signaling pathway in berberine-induced reduction of renal ischemia-reperfusion (I/R) injury in mice.Methods:Thirty SPF healthy male C57BL/6 mice, aged 6-8 weeks, weighing 18-22 g, were divided into 5 groups ( n=6 each) using a random number table method: sham operation group (S group), renal I/R group (RIR group), berberine+ I/R group (B group), berberine+ I/R+ SIRT1 inhibitor EX527 group (BE group) and berberine+ I/R+ Nrf2 inhibitor ATRA group (BA group). After the right kidney was removed, the left renal artery was clamped for 45 min followed by reperfusion to establish the model of renal I/R injury.In B, BE, and BA groups, berberine 100 mg·kg -1·d -1 was given for intragastric administration at 14 days before surgery.In group BE and group BA, EX527 5 mg·kg -1·d -1 and ATRA 10 mg·kg -1·d -1 were injected intraperitoneally at 3 days before surgery, respectively.The equal volume of normal saline was given for 14 consecutive days in group S and group RIR.Blood samples were collected from orbital vein at 24 h of reperfusion for measurement of serum blood urea nitrogen (BUN) and creatinine (Cr) concentrations, for determination of the interleukin-1 beta (IL-1β) and tumor necrosis factor-alpha (TNF-α) contents (by enzyme-linked immunosorbent assay) and expression of SIRT1, Nrf2, apoptosis-associated speck-like protein containing CARD (ASC), caspase-1, nucleotide-binding oligomerization domain-like receptor containing pyrin domain (NLRP3) (by Western blot) and for examination of the pathological changes of renal tubules (with a light microscope). The damage to the renal tubules was scored. Results:Compared with group S, the concentrations of serum Cr and BUN, the contents of renal IL-1β and TNF-α and renal tubular injury score were significantly increased in RIR, B, BE and BA groups, the expression of SIRT1, Nrf2, ASC, caspase-1 and NLRP3 was up-regulated in RIR, BE and BA groups, and the expression of SIRT1, Nrf2, caspase-1 and NLRP3 was up-regulated in group B ( P<0.05). Compared with group RIR, the concentrations of serum Cr and BUN, the contents of renal IL-1β and TNF-α and renal tubular injury score were significantly decreased in B, BE and BA groups, the expression of SIRT1 and Nrf2 in group B, Nrf2 and ASC in BE group and SIRT1, ASC and caspase-1 in BA group was up-regulated, and the expression of ASC, caspase-1 and NLRP3 in group B, SIRT1 and NLRP3 in BE group and Nrf2 in BA group was down-regulated ( P<0.05). Compared with group B, the serum concentrations of Cr and BUN, the contents of IL-1β and TNF-α and renal tubular injury score were significantly increased in BE and BA groups, the expression of ASC, caspase-1 and NLRP3 in BE and BA groups was up-regulated, and the expression of SIRT1 in BE and Nrf2 in BA groups was down-regulated ( P<0.05). Conclusion:SIRT1/Nrf2 signaling pathway is involved in the process of berberine-induced reduction of renal I/R, which is related to inhibiting pyroptosis in mice.

Objective:To observe the changes of somatosensory evoked potential (SEP) in the upper limbs of patients with acute middle cerebral artery (MCA) cerebral infarction, and to explore its relationship with neurological impairment.Methods:From January 2015 to December 2016, 62 patients with 38 cases of male and 24 women of cerebral infarction who were treated in the department of neurology, Kailuan General Hospital were selected for a retrospectively prospective cohort study, including 38 males and 24 females.aged (66.7 ± 10.9) years old and ranging from 33.0 to 85.0 years old.According to the side of cerebral infarction, 37 cases were divided into left MCA group and 25 cases into right MCA group.During the 48 hours of admission, the electromyography evoked potential meter was used to detect the upper limb SEP, and the peak latency, amplitude and electrical activity waveform of the cerebral cortex potentials N20, P25 and N35 were recorded.Results:The results of SEP in the contralateral limbs of the left and right MCA cerebral infarction group were as follows: 1 case (2.70%) and 5 cases (20.00%) of normal median nerve; 36 cases (97.30%) and 20 cases (80.00%) of abnormality.The ratio of median nerve abnormalities in the group was statistically significant (χ 2=12.577, P<0.001). The ulnar nerve was normal in 3 cases (8.11%), 4 cases (16.00%); 34 cases (91.89%) and 21 cases (84.00%) were abnormal.There was no statistically significant difference between the two groups (χ 2=2.320, P=0.128). The peak latency and/or amplitude of each peak decreased in 34 groups (60.71%) and 33 cases (60.00%) of the ulnar nerve; the waveform of electrical activity disappeared, 22 cases (39.29%) of median nerve and 22 cases of ulnar nerve (40.00%). The peak latency and/or amplitude decreased, the electrical activity waveform disappeared, and the median nerve and ulnar nerve were compared, and the difference was not statistically significant (χ 2=0.021, P=0.885). The National Institue of Health Storke Scale(NIHSS) scores of left and right MCA cerebral infarction group were 34 (91.89%) and 19 (76.00%) respectively.Among them, the disappearance of electrical activity waveform were 18 cases (52.94%) and 4 cases (21.05%)of median nerve; 18 cases (52.94%) and 4 cases (21.05%) of ulnar nerve.The SEP electrical activity waveform disappeared in patients with moderate or higher neurological impairment, and the median nerve and ulnar nerve were statistically significant (χ 2=20.613, 20.613, all P<0.001). Conclusion:The median nerve and ulnar nerve SEP of the contralateral upper limb, which is dominated by the acute middle cerebral artery cerebral infarction, were abnormally changed.The main manifestations were that the latency of each peak of N20, P25 and N35 was prolonged and/or the amplitude was significantly decreased, and the waveform of SEP electrical activity disappeared.In addition, the disappearance of SEP wave activities only occurred in moderate and above neurological damage
