ObjectiveTo assess the therapeutic effectiveness and safety of the traditional Chinese medicine compound Shenlong decoction in addressing the symptoms of pulmonary deficiency and stasis in patients with idiopathic pulmonary fibrosis （IPF）. MethodsSixty eligible patients with lung deficiency and collateral stasis syndrome of IPF were randomly assigned to the observation （30 patients） and control groups （30 patients）. All patients underwent standard Western medical therapy. Additionally，the observation group received Shenlong decoction granules，while the control group received a placebo. Both treatments were packaged in four doses of 10.5 g each，taken twice daily for three months. The indexes of the patients during the treatment cycle were observed，and the main indexes include traditional Chinese medicine （TCM） syndrome scores and 6 min walk test （6MWT）. The secondary indexes include pulmonary function test ［actual value/expected value of total lung volume （TLC%），actual value/expected value of vital capacity（FVC%），actual/predicted diffusing capacity of the lung for carbon monoxide（DLCO%），actual/predicted forced expiratory volume in one second （FEV₁%），and FEV₁/ forced vital capacity （FVC）］，blood gas analysis ［arterial blood diathesis partial pressure of oxygen （PaO₂），partial pressure of carbon dioxide （PaCO₂），and arterial oxygen saturation （SaO₂）］，serum inflammatory factors ［transforming growth factor-β₁ （TGF-β₁），interleukin-4 （IL-4），interleukin-13 （IL-13），interleukin-12 （IL-12），and gamma-interferon （IFN-γ）］，and quality of survival evaluation ［St George's Respiratory Questionnaire （SGRQ） score］. The patients' clinical manifestations were determined at the end of the treatment， and the occurrence of adverse events was recorded. ResultsA total of 53 patients completed the study，comprising 27 in the control group and 26 in the observation group. Upon completion of the treatment period，the control group achieved a total effective rate of 33.33% （9/27），whereas the observation group demonstrated a total effective rate of 53.85% （14/26），which was statistically superior to the control group （χ²=4.034，P<0.05）. After the treatment，the TCM syndrome scores，6MWT，DLCO%，FEV₁%，PaO₂，PaCO₂，TGF-β₁，IL-4，IL-13，IL-12，and IFN-γ in the two groups were all significantly improved （P<0.01）. Compared with those in the control group after treatment at the same period，the TCM syndrome scores，6MWT，PaO₂，and PaCO₂ were significantly improved in the observation group after 60 days and 90 days of medication （P<0.01）. Three months after the end of medication，the SGRQ score in the observation group showed significant improvement when compared to that in the control group （P<0.05），and no severe adverse events were reported during the follow-up period. ConclusionCompound Shenlong decoction can alleviate clinical symptoms such as shortness of breath and wheezing in patients with lung deficiency and collateral stasis syndrome of IPF，enhance exercise tolerance，improve the quality of life，and have certain potential advantages in improving pulmonary function.

Lophatheri Herba (Danzhuye in Chinese) is derived from the dried stems and leaves of Lophatherum gracile and has a long history of use as a medicinal and food source. Flavonoids and phenolic acids are the main active ingredients in Lophatheri Herba, which produce diuretic, anti-inflammatory, and antipyretic effects. Flavonoid glycosides and hydroxybenzoic acids are respectively the main structure in 44 flavonoids and 16 phenolic acids obtained from Lophatheri Herba. Modern pharmacological studies have found that the main chemical constituents of Lophatheri Herba play important roles in anti-inflammatory, cardioprotective, hepatoprotective and hypoglycaemic effects. Studies have demonstrated that flavonoid monomers, for example, luteolin, isoorientin, luteolin-7-O-β-D-glucoside and apigenin are more effective in exerting the above pharmacological effects. In addition, Lophatheri Herba is used in different food products as the main ingredient or as an accessory. This review describes Lophatheri Herba in terms of its chemical composition, pharmacological effects and efficacy, food development and applications, and clinical utility, and discusses the problems facing its use. This study provides valuable ideas and a scientific basis for the future development and use of L. gracile.

Objective We aimed to assess the serum levels of the glycolysis-related protein hypoxia-inducible factor-1α(HIF-1α)and cytokines in patients with relapsing-remitting multiple sclerosis(RRMS)before and after treatment with the traditional Chinese medicine Yishen Daluo Decoction,as well as their correlation with clinical parameters,and explore the immune regulatory mechanism of Yishen Daluo Decoction on multiple sclerosis.Methods Twenty-eight patients with RRMS in remission recruited from May 2018 to January 2022 in the Multiple Sclerosis Clinic at Dongzhimen Hospital,Beijing University of Chinese Medicine were retrospectively included.Comparisons were made with paired samples from 13 of them before and after Yishen Daluo Decoction treatment.A total of 20 gender-and age-matched healthy controls(HCs)were also recruited.Clinical information was collected from all of the subjects,and the neurological impairments of RRMS patients were assessed with the Expanded Disability Status Scale(EDSS)score.ELISA and SP-X multiplex cytokine assays were used to measure the serum levels of HIF-1 α and 10 cytokines(IL-1β,IL-4,IL-5,IL-6,IL-8,IL-10,IL-12p70,IL-22,IFN-γ,and TNF-α),respectively.Spearman's method was used to analyze the correlation between the serum levels of HIF-1α and cytokines,and the correlation between the serum levels of HIF-1α and cytokines and patients'clinical indicators,including disease duration,the number of attacks,and the EDSS score.Results Serum HIF-1α,IL-4,IL-6,IL-8,IL-10,IL-12p70,IFN-γ,and TNF-α levels in the RRMS group were significantly higher than those in the HC group(P＜0.05).Serum levels of HIF-1α,IL-4,IL-6,and IL-12p70 in the Yishen Daluo Decoction-pre group were significantly higher than those in the Yishen Daluo Decoction-post group(P＜0.05).In addition,the serum HIF-1α level was positively correlated with IL-6(r=0.452,P=0.016)and TNF-α(r=0.524,P=0.004)levels in patients with RRMS.The IFN-γ level was negatively correlated with the EDSS score(r=-0.423,P=0.025),the IL-4 level was negatively correlated with disease duration(r=-0.385,P=0.043),and the TNF-α level was positively correlated with disease duration(r=0.397,P=0.037).Conclusion The regulatory mechanism of Yishen Daluo Decoction on immune imbalance in RRMS may be related to its ability to reduce the serum levels of the glycolysis-related protein HIF-1α in RRMS patients.It is also related to the levels of various inflammatory cytokines.

In order to establish the isolation,culture and identification method of cow bone marrow-derived macrophages,three different media(RPMI-1640,DMEM,DMEM/F12)were added with 20％fetal bovine serum(FBS),2.4％chlorine-streptomycin,1.2％glutamine(Gln),and M-CSF(20 ng/mL),respectively,to induce the monocytes extracted from the bone marrow of dairy cows to become macrophages.The induced M0 macrophages were polarized into M1-type macrophages by adding lipopolysaccharide(LPS).The morphology of macrophages was observed by optical mi-croscope at day 1,4 and 7,and the differences of differentiated macrophages between the three media were compared.The effects of prostaglandin D2(PGD2)-DP2 receptor pathway on the secre-tion of cytokines(IL-6,TNF-α)induced by Escherichia coli and phagocytosis of macrophages were also investigated.The results showed that the morphological changes of cells cultured in the medium of RPMI-1640 were the most obvious and the number was large.A large number of char-acteristic markers of mononuclear macrophages were detected(M0 markers:CD1 1b,CD14;M1 markers:CD11b,CD80)expression,M0 and M1 macrophage purity were 79.9％and 93.5％,re-spectively.COX-2 and H-PGDS gene expressions were significantly increased in E.coli group com-pared with the blank control group.The secretion of PGD2also increased significantly(P＜0.000 1).DP2 receptor inhibitors(CAY10471,CAY10595)could significantly inhibit the secretion of E.coli in-duced pro-inflammatory cytokines(IL-6,TNF-α)and significantly enhance the killing effect of macrophages on E.coli.The above results showed that the induced cells had the characteristic mor-phology and immunophenotype of macrophages.E.coli can induce the production of PGD2 in mac-rophages,and the PGD2-DP2 pathway regulates the secretion of cytokines in E.coli infected macro-phages.

Objective:To investigate the short-term effect of Helicobacter pylori ( HP) eradication on intraoperative bleeding during endoscopic submucosal dissection (ESD) for early gastric cancer. Methods:Patients who underwent ESD for early gastric cancer in Shanghai East Hospital from September 2021 to September 2023 were retrospectively analyzed for endoscopic, pathological and clinical data. The patients with current HP infection were included in the current infection group, and those who underwent eradication therapy within 10 weeks and successfully eradicated were included in the short-term after eradication group. The occurrence of intraoperative bleeding was compared. Results:A total of 345 patients were analyzed, with 156 in the current infection group and 189 in the short-term after eradication group. Compared with the current infection group, short-term after eradication group was effective in reducing the intraoperative bleeding rate [6.3% (12/189) VS 12.8% (20/156), χ2 =4.253, P=0.039] and significantly reduced the duration of operation (29±9 min VS 38±14 min, t=2.667, P=0.008). Intraoperative bleeding was significantly reduced in short-term after eradication group in lesions of the upper 1/3 of the stomach [12.5% (5/40) VS 32.1% (9/28), χ2 =3.887, P=0.049], while there were no significant differences in intraoperative bleeding between the current infection group and the short-term after eradication group in lesions of the middle 1/3 [5.4% (2/37) VS 10.0% (3/30), χ2 =0.506, P=0.477] and lower 1/3 [4.5% (5/112) VS 8.2% (8/98), χ2 =1.231, P=0.267] of the stomach. Conclusion:HP eradication therapy can effectively reduce intraoperative bleeding in ESD and significantly reduce the duration of operation in a short-term. For individuals with early gastric cancer and HP infection, undergoing eradication therapy before ESD is recommended, particularly for lesions situated in the upper 1/3 of the stomach.

OBJECTIVE To investigate the inhibitory effect of berberine （BER） on the invasion and migration of human renal carcinoma cells and its potential mechanism. METHODS Using human renal carcinoma OSRC-2 cell as object， alamarBlue assay was adopted to detect the inhibitory effects of 0 （control group）， 25， 50， 75， 100， 125， 150， 175 and 200 μmol/L BER on the proliferation of OSRC-2 cell after treatment for 24 h and 48 h. After treated with 0（control group）， 50， 100 μmol/L BER for 48 h， the effect of BER on cell cycle was analyzed by flow cytometry. The migration of OSRC-2 cells in 24 h and 36 h was observed by cell scratch test， and the invasion ability of OSRC-2 cells in 24 h was detected by Transwell assay. The protein expression of methyltransferase-like 3 （METTL3） was detected by Western blot after treatment for 48 h， and RNA methylation quantification kit was used to detect the levels of N6-methyladenosine （m6A） in OSRC-2 cells. RESULTS Compared with control group， BER at different concentrations could significantly decrease the survival rate of OSRC-2 cells （P＜0.01）， and showed a dose-dependent and time-dependent manner. After 48 h of BER treatment at 50， 100 μmol/L， the cell was arrested in G0/G1 phase （P＜0.01）. Compared with control group， the migration and invasion abilities of cells in 50， 100 μmol/L BER group were significantly decreased （P＜0.05 or P＜0.01）； the protein expression of METTL3 and the level of m6A in RNA were significantly decreased （P＜0.01）. CONCLUSIONS BER can inhibit level of m6A by down-regulating the expression of METTL3， thereby inhibiting the invasion and metastasis of human renal carcinoma cells.

Background Exposure to heavy metals has potential adverse impacts on human health, and the concentration of heavy metals in abandoned mining areas may still be higher than that in general areas, so the health risk assessment in such areas cannot be ignored. Objective To explore the health risk of heavy metal exposure and the spatial distribution characteristics of associated main metals in a typical abandoned mining area. Methods Environmental samples of irrigated soil, rice, and drinking water were collected from 13 natural villages under the jurisdiction of a township in Liuzhou, Guangxi from November to December 2019, where a typical abandoned mining was located. Finally, 13 irrigation soil samples, 11 rice samples, and 13 drinking water samples were collected. The concentrations of six metals and metalloid elements in each environmental sample were detected by inductively coupled-plasma mass spectrometry (ICP-MS), including cadmium (Cd), arsenic (As), lead (Pb), chromium (Cr), copper (Cu), and zinc (Zn). At the same time, 251 local residents were recruited for health risk assessment. Model parameters such as body weight, rice intake, and drinking water intake of local residents were obtained through field survey, and the median metal concentration of each environmental sample was taken as the risk assessment parameter of the region. The health risk of heavy metal exposure of local residents was assessed by using oral health risk assessment model of U.S. Environmental Protection Agency. The spatial distribution characteristics of health risks associated with heavy metals were evaluated by empirical Bayes interpolation method using Geographic Information System (GIS) technology. Results The positive rates of Cd, As, Pb, Cr, Cu, and Zn in the irrigated soil samples were 100.00%. The positive rate of Pb was 63.64% in the rice samples, while the rates of other metals were 100.00%. The positive rates of Cd, As, Pb, Cr, Cu, and Zn in the drinking water samples were 53.85%, 76.92%, 92.31%, 15.38%, 84.62%, and 100.00%, respectively. The results of non-carcinogenic risk assessment of oral exposure to heavy metals suggested that the contribution of heavy metals causing non-carcinogenic risk from high to low was As (70.52%) > Cd (18.03%) > Zn (6.63%) > Cu (4.12%) > Pb (0.64%) > Cr (0.06%), and the corresponding estimated non-carcinogenic risk values were 3.54 × 10⁰, 9.05 × 10⁻¹, 3.33 × 10⁻¹, 2.07 × 10⁻¹, 3.23 × 10⁻², and 5.42 × 10⁻⁴, respectively. The results of carcinogenic risk assessment of oral exposure to heavy metals suggested that the contribution of studied metals from high to low was Cd (87.00%) > As (10.24%) > Cr (2.60%) > Pb (0.16%), and the estimated carcinogenic risks were 4.35× 10⁻³, 5.12 × 10⁻⁴, 1.30 × 10⁻⁴, and 3.08 × 10⁻⁷, respectively. Rice was the leading media associated with non-carcinogenic risk and carcinogenic risk (99.4% and 99.8% respectively). The spatial distribution characteristics of GIS showed no obvious regularity in the distribution of As in irrigated soil, rice, and drinking water. In rice and irrigated soil, the content of Cd in the villages adjacent to the mining area was obviously higher than that in the other villages, while in drinking water, the content in the villages far away from the mining area was higher. Conclusion As and Cd are the main heavy metals that increase the health risk of local residents in a typical abandoned mining area, and the distribution characteristics of the two heavy metals in different environmental media are not completely consistent.
