This study systematically elucidates the contemporary understanding of the theory of"the lung and large intestine being interior-exteriorly related"within both traditional Chinese and Western medical theoretical frameworks,while providing an in-depth summary of national medical master Han Mingxiang's clinical experience in diagnosing and treating phlegm-heat obstructing lung syndrome in acute exacerbation chronic obstructive pulmonary disease(AECOPD).Theoretically,this doctrine originates from the Huangdi Neijing and has been developed into a comprehensive system by subsequent medical practitioners.Modern medical research from embryological,microbiological,and other perspectives has confirmed the close physiological and pathological relationship between the lung and intestine,particularly evidenced by the proposed"gut-lung axis"theory.Based on over 6 decades of clinical practice,professor Han identified the core pathogenesis of AECOPD as involving"phlegm,blood stasis,toxins,and deficiency,"with phlegm-heat obstructing lung syndrome being the most prevalent manifestation.The pathological characteristics include impaired lung qi descent,internal accumulation of phlegm-heat,and intestinal obstruction.The therapeutic approach emphasizes"clearing heat and resolving phlegm,relieving cough and asthma"as the primary treatment principle,focusing on"clearing lung heat,eliminating phlegm pathogens,and descending rebellious qi",while adhering to the concept of"simultaneous treatment of lung and intestine."In terms of herbal prescription,professor Han skillfully employs modified Xuanbai Chengqi decoction,which integrates lung-ventilating,phlegm-resolving,and purgative effects.Importantly,he emphasizes the precise timing and dosage of purgative herbs,particularly for patients with deficiency patterns,advocating discontinuation or dose reduction once intestinal patency is achieved to avoid overtreatment.For remission phase management,professor Han advocates the"reinforcing earth to generate metal"approach using modified Bufei decoction combined with Yigong powder,which strengthens spleen qi to nourish lung function.This therapeutic strategy embodies the fundamental treatment principle of"treating the acute manifestations first,then addressing the root cause."This research not only deepens the understanding of classical Chinese medical theories but also provides more scientifically grounded intervention strategies for the clinical prevention and treatment of lung distension.The findings offer valuable insights into integrative approaches for AECOPD management,combining traditional wisdom with contemporary medical understanding.

OBJECTIVE: To screen the optimal regimen of acupuncture and moxibustion for obstructive sleep apnea hypopnea syndrome (OSAHS), so as to provide the evidences for clinical decision-making. METHODS: From 7 databases in Chinese and English i.e. the Full-Text Database of China Journal Network (CNKI), Wanfang Data Knowledge Service Platform (Wanfang), VIP Information Chinese Journal Service Platform (VIP), Chinese Biomedical Literature Database (SinoMed), PubMed, Web of Science (WOS) and Cochrane Library, randomized controlled trial (RCT) articals of OSAHS treated with acupuncture and moxibustion were searched. The quality of evidence was evaluated with the modified Jadad scale, the evaluation index was established and the optimal regimen of acupuncture and moxibustion for OSAHS was screened by multi-index decision analysis. RESULTS: A total of 10 RCTs were included, and the filiform needling therapy was optimal in treatment of OSAHS. The acupoints included Lianquan (CV23), Danzhong (CV17), Zhongwan (CV12), and bilateral Kongzui (LU6), Pishu (BL20), Fenglong (ST40), Zusanli (ST36), Yinlingquan (SP9) and Zhaohai (KI6). Zusanli (ST36) received the reinforcing method, Pishu (BL20) and Fenglong (ST40) were stimulated with the reducing technique, and the rest acupoints with the uniform reinforcing-reducing. Each acupoint was manually manipulated once every 10 min during the needle retention for 30 min. Acupuncture was delivered once a day, 5 times a week and for consecutive 4 weeks. Among the included literature, the severity of disease was not reported in detail, the filiform needling was the dominant intervention, the local acupoints such as Lianquan (CV23) and Panglianquan (Extra) were mainly selected. The apnea-hypopnea index and the minimum oxygen saturation were taken as the evaluation indexes, and the effect was evaluated in reference to the generally accepted standards. The attention to safety evaluation was insufficient, the report on methodology was not adequate and the quality was low. CONCLUSION Filiform needling is the dominant therapy of acupuncture and moxibustion for OSAHS, and the local acupoints are considered specially. But the quality of clinical research should be improved.

Objective:To explore the efficacy of adjusting the dose of imatinib dose in the context of therapeutic drug monitoring (TDM) in patients with gastrointestinal stromal tumors (GISTs) who are receiving adjuvant therapy after complete resection of their tumors.Methods:This was a descriptive study. Inclusion criteria were (1) complete surgical resection with a pathological diagnosis of GIST, (2) postoperative adjuvant therapy with imatinib and dosage adjustment, (3) multiple TDM of imatinib, and (4) complete clinical, pathological, and follow-up data. The data of 70 patients with GISTs treated at Union Hospital, Tongji Medical College, Huazhong University of Science and Technology between January 2015 and December 2023 were collected retrospectively. The study cohort comprised 15 (21.4%) men and 55 (78.6%) women of median age 60 years (range: 25–82). Of the eligible patients, 49 (70.0%) were at high-risk, 14 (20.0%) at intermediate-risk, six (8.6%) at low-risk, and one (1.4%) at very low risk. Patients were followed up by the gastrointestinal stromal tumor clinic every 2–3 months and their plasma concentrations of imatinib were checked. The dose was adjusted to 300 mg/d or 200 mg/d depending on whether they had had ≥ grade III adverse reactions, and whether the first plasma concentration of imatinib was ≥ 1,500 μg/L or between the expected range of 760 μg/L–1,100 μg/L. Studied indicators included adverse reactions, quality of life before and after dose adjustment, and overall survival and recurrence-free survival (RFS) after dose adjustment.Results:Before dose adjustment, all 70 patients received 400 mg of imatinib daily, with initial TDM values of 1,900 ± 568 μg/L, for a median duration of 8.3 months. After dose adjustment, 60 patients received 300 mg daily, with a TDM of 1,216 ± 350 μg/L, whereas 10 received 200 mg daily, with a TDM of 1,023 ± 269 μg/L. The median duration of treatment after dose adjustment was 23.4 months. Compared with those whose dosages were not adjusted, the incidence of bone marrow suppression was significantly lower (74.3% [52/70] vs. 51.4% [36/70], χ 2=9.202, P=0.010); as were the incidences of edema (95.7% [67/70] vs. 50.0% [35/70], χ 2=40.526, P<0.001); skin reactions (70.0% [49/70] vs. 32.9% [23/70), χ 2=22.495, P<0.001); and gastrointestinal reactions (38.6% [27/70] vs. 10.0% [7/70], χ 2=15.899, P<0.001) in those whose dosages were adjusted. The average total scores for physical health before and after dose adjustment were 76 ± 5 and 88 ± 4, respectively; whereas the mental health scores were 75 ± 6 and 89 ± 4, respectively. The median follow-up period was 36 months (range 6–126). During the first 3 years of follow-up, five high-risk patients with non-gastric GISTs developed recurrences. The 3-year overall survival rate was 100%, and the 3-year RFS rate was 92.8%, high-risk patients having a 3-year RFS rate of 89.8%. Conclusion:The adverse reactions and quality of life of GIST patients with severe adverse reactions to adjuvant imatinib therapy after complete resection can be mitigated by appropriately reducing the dosage of imatinib under the guidance of TDM.

For the high-risk population, early screening and diagnosis are important measures to achieve good control of liver cancer and reduce the burden of liver cancer, and determining the high-risk population of liver cancer and formulating appropriate liver cancer screening strategies are the key to realizing the early screening and diagnosis of liver cancer. The risk assessment model for liver cancer is an important method for rapid and convenient identification of the high-risk population of liver cancer. Based on the risk stratification of liver cancer, the methods such as imaging technology, serological markers, liquid biopsy, metabolomics, and glycomics can be used for accurate early screening and diagnosis of liver cancer, so as to achieve the goal of early treatment.

Objective:To evaluate the effect of long-term intake of ω-3 polyunsaturated fatty acids (ω-3 PUFAs) on the activation of hippocampal microglia in a mouse model of postoperative cognitive dysfunction (POCD).Methods:Ninety-six clean-grade healthy male C57BL/6 mice, aged 8 weeks, weighing 18-24 g, were stratified according to body weight and divided into 4 groups ( n=24 each) by a random number table method: control diet group (group C), ω-3 PUFAs group (group ω), control diet plus POCD group (group C+ P) and ω-3 PUFAs plus POCD group (group ω+ P). Mice were fed a special ω-3 PUFAs diet (DHA 0.14 g/100 g, EPA 0.03 g/100 g) for 12 weeks in group ω and group ω+ P, while mice were fed with a control diet for 12 weeks in group C and group C+ P.Tibial fracture procedures were performed under isoflurane anesthesia to develop the POCD model after 12 weeks of feeding.The fear conditioning test and Y maze test were performed on 1st and 3rd days after developing the model.The mice were sacrificed after behavioral tests, and the hippocampal tissues were removed for determination of the contents of docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) (by gas chromatography-mass spectroscopy), density of Iba-1 positive microglia (by immunofluorescence staining), and expression of mature brain-derived neurotrophic factor (mBDNF) and precursor brain-derived neurotrophic factor (pro-BDNF) (by Western blot), and contents of interleukin-1beta (IL-1β) and interleukin-6 (IL-6) (by enzyme-linked immunosorbent assay). Results:Compared with group C, the contents of DHA and EPA were significantly increased, the percentage of freezing time in the contextual test was increased, mBDNF/pro-BDNF ratio was increased ( P<0.05), no significant change was found in the rotation accuracy in Y maze test, density of Iba-1 positive microglia and contents of IL-1β and IL-6 in hippocampus ( P>0.05) in group ω ( P<0.05), and no significant change was found in the contents of DHA and EPA ( P>0.05), the percentage of freezing time in the contextual test and accuracy of rotation in Y maze test were decreased on 1st and 3rd days after operation, the density of Iba-1 positive microglia and contents of IL-1β and IL-6 were increased, and mBDNF/pro-BDNF ratio was decreased in group C+ P ( P<0.05). Compared with group C+ P, the contents of DHA and EPA were significantly increased, the percentage of freezing time in the contextual test and accuracy of rotation in Y maze test were increased on 1st and 3rd days after operation, the density of Iba-1 positive microglia and contents of IL-1β and IL-6 were decreased, and mBDNF/pro-BDNF ratio was increased in group ω+ P ( P<0.05). Conclusions:Long-term intake of ω-3 PUFAs can improve cognitive function in a mouse model of POCD, and the mechanism may be related to inhibition of activation of hippocampal microglia, reduction of inflammatory responses, and thus increasing the mBDNF/Pro-BDNF ratio.

Objective To evaluate the significance of serum 8-hydroxy-deoxyguanosine acid ( 8-OHdG) in the diagnosis of nonalcoholic steatohepatitis ( NASH).Methods Patients or healthy subjects were enrolled at the Second Hospital of Tianjin Medical University and the Second People ′s Hospital of Tianjin from May 2013 to December 2015.A total of 41 patients with nonalcoholic fatty liver disease were enrolled in the study , including 20 nonalcoholic simple fatty liver ( NAFL) patients and 21 NASH patients whose diagnosis were proven by liver biopsy.The other 32 healthy subjects were studied as controls.Serum 8-OHdG, ALT, AST and GGT were tested.Nonalcoholic fatty liver disease activity score ( NAS ) and expression of 8-OHdG in liver was investigated between NAFL patients and NASH patients.The correlations between serum 8-OHdG and serum ALT , AST, GGT, and 8-OHdG in liver tissue in NASH group were investigated.In addition , the receiver operating characteristic ( ROC) curve analyses for ALT and 8-OHdG levels were performed in NAFL patients and NASH patients , and the cut-off value was determined.Results Serum 8-OHdG values in healthy controls , NAFL and NASH patients were (0.19 ±0.16) μg/L, (0.22 ±0.16) μg/L, (0.42 ±0.21) μg/L respectively.The serum 8-OHdG and serum ALT, GGT and 8-OHdG in liver tissue were all positively correlated in NASH group with respective correlation coefficient r values as 0.454 7, 0.382 9, and 0.497 6.AUC of 8-OHdG was 0.901 with cut-off value 0.39 μg/L.Its sensitivity was 88.3%and specificity was 81.5%, which were higher than those of ALT.Conclusion The value of serum 8-OHdG would be used as a marker for the diagnosis of NASH.

Objective To study the therapeutic effect of anti-CD80 bivalent antibody on mouse lu-pus nephritis and to explore the possible molecular mechanism. Methods A mouse model of lupus nephritis was established through intraperitoneal injection of 0. 5 ml of pristine in female C57BL/6J mice. Appearance of urinary protein and significantly increased levels of peripheral antinuclear antibody ( ANA) and anti-doub-le-stranded DNA ( anti-dsDNA) antibody in the fourth month after injection indicated that the mouse model was established successfully. Then the mice were divided into two groups including anti-CD80 bivalent anti-body intervention group (injected with 200μg of anti-CD80 bivalent antibody at day 1, 3, 5, 8 and 15, fol-lowed by three times of injection with an interval of one month) and model group ( injected with the same protein using the same strategy). A normal control group was set up accordingly. Albustix test paper was used to monitor the dynamic changes in mouse urinary protein. Flow cytometry was used to analyze the acti-vation of immune-related cells in spleen. Levels of autoantibodies ( ANA and anti-dsDNA) and levels of IFN-γ and IL-4 in serum were detected by indirect immunofluorescence assay. Renal tissue samples were an-alyzed with hematoxylin and eosin ( HE) staining and immunocomplex ( IC) assay. Results Urinary pro-tein level of the anti-CD80 bivalent antibody intervention group was significantly lower than that of the model group (P<0. 05). Activated macrophages, dendritic cells, neutrophils and B cells in spleen tissues of the anti-CD80 bivalent antibody intervention group were significantly less than those of the model group ( P<0. 05), and the numbers of CD4+ and CD154+ T cells were significantly less than those of the model group (P<0. 05). Positive rates and titers of ANA and dsDNA in serum samples of the intervention group were lower than those of the model group (P<0. 05). Levels of IFN-γand IL-4 in serum samples of the interven-tion group were decreased as compared with those of the model group (P<0. 05). HE staining and immuno-fluorescence assay showed that glomerular inflammatory injury and necrosis were alleviated and kidney im-mune complex deposition was reduced after anti-CD80 bivalent antibody intervention. Conclusion Anti-CD80 bivalent antibody specifically binds to the CD80 molecule on antigen presenting cell surface, blocks the CD80/CD28 co-stimulatory signaling pathway and down-regulates the body′s immune response, which al-leviates and reverses the lupus-like nephritis-induced pathological damages in mice.
