Objective To investigate the effects of in vitro culture with different concentrations of glucose and serum on hypoxia-induced activation and Yes-associated protein(YAP)expression in primary cardiac fibroblasts(CF).Methods Primary CF were isolated from ICR suckling mice with enzyme digestion and then purified using differential adhesion technique.The cells were ran-domly assigned into 6 groups:low glucose high serum group(1.0 g/L glucose+10％serum),high glucose high serum group(4.5 g/L glucose+10％serum),low glucose medium serum group(1.0 g/L glucose+5％serum),high glucose medium serum group(4.5 g/L glucose+5％serum),low glucose serum-free group(1.0 g/L glucose+0％serum)and high glucose serum-free group(4.5 g/L glucose+0％serum).In 24 h after above culture,the cell morphology was observed.Western blotting was used to detect the expression of α-smooth muscle actin(α-SMA),transforming growth factor beta(TGF-β),type Ⅰ collagen(Col Ⅰ).and YAP.Immunofluorescence assay was em-ployed to observe the expression and localization of α-SMA and YAP.EDU staining and cell scratch assay were applied to measure cell proliferation and migration ability,respectively.Results After culture in 1％O2 for 24 h,the cell morphology was gradually altered toward myofibroblasts as the concentration of glucose rose and the serum level fell in the culture medium,especially in the group of high glucose and serum-free.The expression levels of Col Ⅰ,TGF-β,α-SMA and YAP were significantly higher in the high glucose no serum group than in the high glucose high serum group(P＜0.05).The fluorescence intensity of α-SMA was obviously increased in the low glucose no serum group than the low glucose high serum group[(9.23±2.45)％vs(2.40±2.04)％,P＜0.05].Compared to the low-sugar serum-free group,the high glucose serum-free group showed a significant increase in the levels of Col Ⅰ,TGF-β,α-SMA and YAP(P＜0.05).Notably higherα-SMA fluorescence intensity,more YAP nuclear translocation,and enhanced cell migration were observed in the high glucose serum-free group when compared to the high glucose high serum group and the low glucose serum-free group(P＜0.05).Conclusion Under the hypoxic condition of 1％O2,high-glucose serum-free is the most appropriate culture condition to construct an in vitro cell model of hypoxia-induced activation,and the activation of YAP is of most significant im-portance.

OBJECTIVE To conduct a literature review of one case of follicular lymphoma complicated with iliac bone Cryptococcus neoformans infection so as to raise the understanding of such pathogen in the field of HIV-negative Hodgkin's/non-Hodgkin's lymphoma.METHODS The clinical data were collected from one case of follicular lymphoma patient complicated with C.neoformans infection who was treated in Xinrui Hospital of Xin-wu District,Wuxi City on Feb.24,2023 and retrospectively analyzed.All of relevant literatures regarding to the subject were retrieved in Pubmed,CNKI,Wanfang and VIP databases,and the clinical data of the patients with HIV-negative Hodgkin's/non-Hodgkin's lymphoma with C.neoformans infection were screened out and summa-rized.RESULTS The case was a 28-year-old male and had the underlying disease of follicular lymphoma.The C.neoformans was detected by iliac bone histopathology and metagenome next generation sequencing(mNGS).The condition of the patient improved after the treatment with amphotericin B cholesterol sulphate com-pound and fluconazole.A total of 28 patients,with this case included,were involved in the literature review,23 of whom were male,and 5 were female,and the age ranged between 16 and 79 years old.With respect to major in-fection sites,there were 15(53.57％)cases of cerebral infection,9(32.14％)cases of blood infections,7(25.00％)cases of pulmonary infection,4(14.285％)cases of skin infections,2(7.14％)cases of muscle tis-sue infections,2(7.14％)cases of pleural effusion infections,2(7.14％)cases of bone infections and 1(3.57％)case of bone marrow infection.Totally 11 patients had disseminated Cryptococcus infection,accounting for 39.28％.CONCLUSIONS The C.neoformans infection is seldom detected in the patients with HIV-negative Hodgkin's/non-Hodgkin's lymphoma.The brain is the major infection site with the high probability of dissemina-ted infection.It is necessary for the hospital to deepen the understanding of the pathogen in the field of HIV-negative Hodgkin's/non-Hodgkin's lymphoma.

Aim To investigate the effect of Brusatol a-gainst small cell lung cancer(SCLC)and its potential mechanism.Methods CCK-8 assay and flow cytome-try were used to detect the cytotoxic effect of Brusatol on SCLC cells.Western blot was employed to measure the expression levels of apoptosis-related proteins,in-cluding cleaved poly(ADP-ribose)polymerase(cleaved-PARP),B-cell lymphoma 2(Bcl-2)and Bcl-2-associated X protein(Bax).Network pharma-cology databases were utilized to identify common tar-gets of Brusatol,SCLC,and apoptosis.Kyoto Encyclo-pedia of Genes and Genomes(KEGG)and Gene On-tology(GO)enrichment analyses were performed on the intersecting genes.Molecular docking simulations between Brusatol and core targets were conducted using the CB-DOCK2 online platform to calculate binding en-ergies and sites.Western blot was further applied to detect the expression levels of signal transducer and ac-tivator of transcription 3(STAT3)and phosphorylated-STAT3(p-STAT3).Results Brusatol inhibited SCLC cell growth and induced apoptosis,significantly downregulating Bcl-2 and cleaved-PARP while upregu-lating Bax expression(P＜0.05).Network pharma-cology analysis revealed 108 common targets of Brusa-tol and SCLC,with the top three core targets being ep-idermal growth factor receptor(EGFR),STAT3,and tumor necrosis factor(TNF).Molecular docking re-sults indicated strong binding affinity between bruceine D and these core targets.Western blot validation con-firmed that bruceine D suppressed the expression of STAT3 and p-STAT3.Conclusion Brusatol exerts anti-SCLC effects by inhibiting STAT3 to induce apop-tosis in SCLC cells.

This study applied the grading of recommendations assessment, development and evaluation(GRADE) system and the integrated evidence chain-based effectiveness evaluation of traditional Chinese medicine(Eff-iEC) to evaluate the evidence for 12 commonly used Chinese patent medicines for the treatment of osteoporosis, which are frequently recommended in guidelines or expert consensuses. The results showed that Xianling Gubao Capsules/Tablets were rated as C(low-level evidence) according to the GRADE system, and as BA~+B~+(intermediate evidence) according to the Eff-iEC system. Jintiange Capsules were rated as C(low-level evidence) by the GRADE system, and as AA~+B(high-level evidence) by the Eff-iEC system. Gushukang Granules/Capsules were rated as C(low-level evidence) by GRADE system, and as BA~+B~+(intermediate evidence) by Eff-iEC system. Zuogui Pills were rated as C(low-level evidence) by GRADE system, and as AA~(++)B~+(high-level evidence) by Eff-iEC system. Qianggu Capsules were rated as D(extremely low-level evidence) by GRADE system, and as AA~+B~+(high-level evidence) by Eff-iEC system. Zhuanggu Zhitong Capsules were rated as D(extremely low-level evidence) by GRADE system, and as BA~+B(intermediate evidence) by Eff-iEC system. Jingui Shenqi Pills were rated as D(extremely low-level evidence) by GRADE system, and as AA~+B(high-level evidence) by Eff-iEC system. Quanduzhong Capsules were rated as D(extremely low-level evidence) by GRADE system, and as AD~+B~+(low-level evidence) by Eff-iEC system. Epimedium Total Flavones Capsules were rated as D(extremely low-level evidence) by GRADE system, and as AAB~+(high-level evidence) by Eff-iEC system. Yougui Pills were rated as D(extremely low-level evidence) by GRADE system, and as AA~(++)B~(+ )(high-level evidence) by Eff-iEC system. Qigu Capsules were rated as D(extremely low-level evidence) by GRADE system, and as BB~+B(intermediate evidence) by Eff-iEC system. Liuwei Dihuang Pills were rated as C(low-level evidence) by GRADE system, and as AA~(++)B~+(high-level evidence) by Eff-iEC system. Overall, the Eff-iEC system provides a more comprehensive assessment of the effectiveness evidence for traditional Chinese medicine(TCM) than the GRADE system. However, it still has certain limitations that hinder its wider promotion and application. In terms of clinical evidence evaluation, both the Eff-iEC and GRADE systems reflect that the current clinical research quality on Chinese patent medicines for the treatment of osteoporosis is generally low. High-quality clinical trials are still needed in the future to further validate clinical efficacy.

Objective:To investigate the role and mechanism of leucine-rich α-2-glycoprotein 1 (LRG1) in the fibrosis of human pterygium fibroblasts (HPFs).Methods:A total of 30 nasal primary pterygium tissues from patients who underwent pterygium excision surgery and 30 nasal normal conjunctival tissues from patients who underwent strabismus correction surgery were collected from the First Affiliated Hospital of Harbin Medical University between January 2022 and March 2023, serving as the pterygium group and normal control group, respectively.LRG1 protein expression in both groups was detected by immunofluorescence staining.The mRNA and protein levels of LRG1 and transforming growth factor-β1 (TGF-β1) were evaluated by quantitative real-time PCR (qRT-PCR) and Western blot.Primary HPFs were cultured from excised pterygium tissues using tissue block adhesion method, and cell morphology was observed.Vmentin and cytokeratin were identified by immunofluorescence staining.HPFs were divided into recombinant human LRG1 (rhLRG1) group and blank control group treated with or without 10 μg/ml rhLRG1 for 24 hours, respectively, and cell migration was evaluated via scratch assay.Additionally, HPFs were divided into blank control group, LRG1 overexpression group and LRG1 knockdown group.HPFs in LRG1 overexpression group and LRG1 knockdown group were transfected with LRG1 overexpression plasmids and small interfering RNA for 24 hours, respectively.TGF-β1 mRNA level was evaluated by qRT-PCR and expression of TGF-β1, fibronectin (FN), type Ⅲ collagen (COL3), and α-smooth muscle actin (α-SMA) proteins were evaluated by Western blot.This study adhered to the Declaration of Helsinki.The study protocol was approved by the Ethics Committee of the First Affiliated Hospital of Harbin Medical University (No.2022IIT026).Written informed consent was obtained from each subject.Results:HPFs were successfully isolated, exhibiting spindle-shaped morphology with whorled arrangement, positive identification for vimentin, and negative immunofluorescence staining for cytokeratin.The migration rate of the rhLRG1 group was (83.01±2.56)%, significantly higher than (50.32±4.97)% of the blank control group ( t=9.59, P<0.001).Immunofluorescence staining results showed that compared with normal conjunctival tissue, LRG1 protein was significantly higher expressed in pterygium tissue and was widely distributed in fibrous connective tissue and epithelial layer.Both mRNA and protein levels of LRG1 and TGF-β1 were significantly higher in the pterygium group than in the normal control group (mRNA: t=10.18, 6.15, both P<0.05.protein: t=6.83, 8.79, both P<0.05).In the LRG1 overexpression group, mRNA level of TGF-β1, and protein levels of FN, COL3 and α-SMA were significantly increased compared with the blank control and LRG1 knockdown groups (all P<0.05). Conclusions:LRG1 promotes fibrosis and enhances the migration ability in HPFs, and its mechanism may be associated with the upregulation of the TGF-β1 signaling pathway.
