Pulmonary sarcoidosis is an immune system disease with an unclear etiology. Guided by the yang-reinforcing method， it is believed that the fundamental pathogenesis of pulmonary sarcoidosis lies in the disharmony between water and fire and the reckless movement of the ministerial fire. The failure of the spleen and stomach to maintain warmth， leading to the production of phlegm and blood stasis， is an important pathogenesis. The invasion of external pathogenic toxins， deeply penetrating into the interior， is considered a triggering factor for the disease. The treatment focuses on supplementing the yang， consolidating the kidney， drawing fire back to its source， warming the yang， benefiting the kidney， and nourishing the spleen to generate metal. It also emphasizes unblocking the yang， transforming turbidity， and eliminating phlegm and blood stasis.

OBJECTIVE: To explore the expression regulation of lipid metabolism gene ABHD5 in testes. METHODS: Differential gene analysis was performed by integrating databases of TCGA and GTEx to identify the target gene ABHD5. The expression trends of ABHD5 gene in testicular carcinoma tissue were analyzed. Human testis single-cell atlases were obtained from the Human Protein Atlas and Male Health Atlas databases to determine the expression distribution of ABHD5 across different testicular cell types. Additionally, the GTEx database was utilized to visualize the expression pattern of ABHD5 in the testis, thereby enhancing the understanding of its transcriptional profile. The relationship between ABHD5 expression and age was assessed through integrated database analysis. Western blotting and immunofluorescence were performed to detect differential expressions of ABHD5 in testicular tissues of young and aged mice respectively. RESULTS: The TCGA database indicated that the expression of ABHD5 in human testicular carcinoma tissue was significantly lower than that in normal testicular tissue which showed a negative correlation with patient survival. ABHD5 was highly expressed in germ cells of the testis reveaked from Human Protein Atlas and Male Health Atlas databases. The stability of ABHD5 protein was crucial for testicular tissue, and its expression decreased with age. Furthermore, Western blot and immunofluorescence staining demonstrated that ABHD5 expression in the testicular tissue of aged mice was significantly lower than that in young mice. CONCLUSION ABHD5 plays an important role in testicular tissue, and may be inseparable from testicular tumors and reproductive aging. However, its mechanism of action remains to be further studied.

OBJECTIVE: Burning solid cooking fuel contributes to household air pollution and is associated with frailty. However, how solid cooking fuel use contributes to the development of frailty has not been well illustrated. METHODS: This study recruited 8,947 participants aged ≥ 45 years from the China Health and Retirement Longitudinal Study, 2011-2018. Group-based trajectory modeling was employed to identify frailty trajectories. Multinomial logistic regression was used to assess the association between solid cooking fuel use and frailty trajectories. Population-attributable fractions were used to estimate the frailty burden from solid fuel use. RESULTS: We identified three frailty trajectories: low-stable ( n = 5,789), moderate-increasing ( n = 2,603), and fast-increasing ( n = 555). Solid fuel use was associated with higher odds of being in the moderate-increasing ( OR: 1.24, 95% CI: 1.08-1.42) and fast-increasing ( OR: 1.48, 95% CI: 1.14-1.92) trajectories. These associations were strengthened by longer solid fuel use ( P for trend < 0.001). Switching to clean fuel significantly reduced the risk of being in these trajectories compared with persistent solid fuel users. Without solid fuel, 8% of moderate- and 19% of fast-increasing trajectories demonstrated frailty development like the low-stable group. CONCLUSION Solid cooking fuel use is associated with frailty trajectories in middle-aged and older Chinese populations.

Objective: To analyze and compare therapy responses, outcomes, and incidence of severe hematologic adverse events of flumatinib and imatinib in patients newly diagnosed with chronic phase chronic myeloid leukemia (CML) . Methods: Data of patients with chronic phase CML diagnosed between January 2006 and November 2022 from 76 centers, aged ≥18 years, and received initial flumatinib or imatinib therapy within 6 months after diagnosis in China were retrospectively interrogated. Propensity score matching (PSM) analysis was performed to reduce the bias of the initial TKI selection, and the therapy responses and outcomes of patients receiving initial flumatinib or imatinib therapy were compared. Results: A total of 4 833 adult patients with CML receiving initial imatinib (n=4 380) or flumatinib (n=453) therapy were included in the study. In the imatinib cohort, the median follow-up time was 54 [interquartile range (IQR), 31-85] months, and the 7-year cumulative incidences of CCyR, MMR, MR(4), and MR(4.5) were 95.2%, 88.4%, 78.3%, and 63.0%, respectively. The 7-year FFS, PFS, and OS rates were 71.8%, 93.0%, and 96.9%, respectively. With the median follow-up of 18 (IQR, 13-25) months in the flumatinib cohort, the 2-year cumulative incidences of CCyR, MMR, MR(4), and MR(4.5) were 95.4%, 86.5%, 58.4%, and 46.6%, respectively. The 2-year FFS, PFS, and OS rates were 80.1%, 95.0%, and 99.5%, respectively. The PSM analysis indicated that patients receiving initial flumatinib therapy had significantly higher cumulative incidences of CCyR, MMR, MR(4), and MR(4.5) and higher probabilities of FFS than those receiving the initial imatinib therapy (all P<0.001), whereas the PFS (P=0.230) and OS (P=0.268) were comparable between the two cohorts. The incidence of severe hematologic adverse events (grade≥Ⅲ) was comparable in the two cohorts. Conclusion: Patients receiving initial flumatinib therapy had higher cumulative incidences of therapy responses and higher probability of FFS than those receiving initial imatinib therapy, whereas the incidence of severe hematologic adverse events was comparable between the two cohorts.

Aim To observe the inhibitory effect of Alpha-momorcharin (α-MMC) on the inflammatory cytokine storm of Ml-type inflammatory macrophages induced by LPS and explore its possible targeting mechanism. Methods Western blot was used to detect the expression of WIL2-S B lymphocytes, H9 T lymphocytes, THP-1 monocytes and M0 macrophages LRP1 receptor protein. CCK-8 method was used to detect the survival rate of the four cells. ELISA was used to detect the expression level of inflammatory cytokines in Ml macrophages. Western blot was used to detect the expression of TLR4 signaling pathway-related protein in Ml macrophages. Results Macrophages had a high density of LRP1 receptors consistent with monocytes; the survival rate of α-MMC on the four cells was positively correlated with the density of this receptor; α-MMC inhibited the expression of inflammatory cytokinesTNF-α, IL-lβ, IL-6, IL-8, MlP-lα and MCP-1 in Ml macrophages in a dose-and time-dependent manner; α-MMC showed significant inhibition to TAKl/pTAK1, p-JNK, p-APl and p-p65 signaling proteins of the TLR4 signaling pathway, and this inhibition could be blocked by the LRP1 receptor blocker RAP. Conclusions α-MMC selectively inhibits macrophage inflammatory cytokine synthesis by inhibiting TAK1 of the TLR4 signaling pathway, which in turn inhibits the downstream NF-ΚB and MAPK pathways, mediated by the LRP1 receptor. The selective immunosuppressive effect of α-MMC on macrophages may make it a very promising agent for the treatment of acute infectious macrophage activation syndrome (MAS).

Aim To investigate the effect of RORα antagonist T0901317 promoting EMT (epithelial-mesenchymal transition) of human gastric cancer MGC803 cells by RORα/β-catenin signal. Methods Cell proliferation was detected by MTT. Cell migration and invasion were detected by cell scratch and Transwell assay respectively. RORα/β-catenin signaling molecules were detected by Western blot and immunofluorescence. RORα binding to β-catenin protein was detected by immunoprecipitation. Results MTT assay showed that the proliferation ability of T0901317 cells increased in a time-dependent manner compared with MGC803 cells (P < 0. 05). Cell scratches and Transwell experiments showed that the migration and invasion ability of T0901317 cells were significantly enhanced compared with MGC803 cells (P < 0. 05). Western blot analysis showed that RORα protein was significantly down-regulated after T0901317 compared with untreated group (P < 0. 05), and total β-catenin protein and nuclear β-catenin in MGC803 cells were up-regulated after T0901317 (P < 0. 05). Compared with the control group, RORα protein binding to β-catenin protein significantly decreased after T0901317 treatment (P < 0. 05). Compared with MGC803 cells treated with T0901317, the long spindle cells increased and the heteromorphism was more obvious. T0901317 significantly up-regulated the expression of Rac1, TGFβ1 and Vimentin in MGC803 cells (P < 0. 05), and inhibited the expression of E-cadherin (P < 0. 05). Conclusion T0901317 can promote the proliferation, migration, invasion and EMT in human gastric cancer MGC803 cells by RORα/β-catenin signal.

Objective:To study the relationship between endoplasmic reticulum stress (ERS) and apoptotic protein and myocardial pathological changes in rats after endostar combined with low-dose X-ray irradiation.Methods:Forty SD rats were evenly divided into four groups: control group (intraperitoneal injection of equal volume physiological saline, once per day, 14 d), endostar group (intraperitoneal injection of endostar 6 mg/kg, once per day, 14 d), irradiation group (15 Gy divided into 3 times X-ray irradiation) and combination group (intraperitoneal injection of endostar after irradiation at the same dose and time as the endostar group). At 1 and 6 months after treatment, myocardial tissues of rats were prepared for HE staining and Masson staining to observe the myocardial histological changes. TUNEL assay was used to detect myocardial cell apoptosis, and ImageJ software was utilized to calculate myocardial collagen volume fraction (CVF). The expression levels of ERS and apoptotic protein glucose-regulated protein 78 (GRP78), protein kinase-like endoplasmic reticulum kinases (PERK), CCAAT/enhancer binding protein homologous protein (CHOP) and cysteine-containing aspartate-specific protease-12 (Caspase-12) were detected by Western blot. One-way ANOVA was conducted using GraphPad Prism 8.0.1 software, and comparison between two groups was conducted using t-test. Results:At 6 months after treatment, the myocardial interstitium in the irradiation and combination groups was widened, showing strip-like or reticular fibrosis changes, and the myocardial interstitium had diffuse collagen fiber deposition. Compared with the control group, CVF was increased significantly (both P<0.01). At 1 and 6 months after treatment, the apoptotic index of myocardial cells in the combination group was significantly higher than that in the control group ( P<0.05, <0.001). At 1 and 6 months after treatment, the expression levels of GRP78 protein in the irradiation and combination groups were increased (all P<0.01), and the expression levels of PERK and CHOP proteins in the combination group were increased compared to those in the control group (both P<0.05). At 6 months after treatment, the expression levels of PERK and CHOP proteins in the irradiation group were increased compared to those in the control group (both P<0.05). Compared with the control group, Caspase-12 expression levels at 1 and 6 months after treatment were increased in the endostar, irradiation and combination groups (all P<0.05). Conclusions:The expression levels of ERS and apoptotic proteins are related to cardiac injury caused by irradiation in rats. After low-dose X-ray combined with endostar treatment, ERS is aggravated and myocardial apoptosis is increased.
