Objective:To evaluate the expression of B7-H3 and CD133 in colorectal cancer(CRC),colorectal polyps,and normal colorectal mucosa and investigate their roles in the development and prognosis of CRC.Methods:Immunohistochemistry was used to detect the ex-pression of B7-H3 and CD133 in 195 CRC,76 villous/tubulovillous adenoma,64 tubular adenoma,30 non-adenomatous polyp,and 10 nor-mal colorectal mucosa samples obtained from The Second Affiliated Hospital of Zhengzhou University between October 2012 and April 2017 and Pengan County People's Hospital between January 2017 and May 2019.Patient age,sex,and immunohistochemical staining results of B7-H3,CD133,and carcinoembryonic antigen were incorporated as risk factors to establish a CRC survival prediction model.Results:B7-H3 and CD133 expression showed an increasing trend from normal mucosa to non-adenomatous polyps,tubular adenomas,villous/tubulovil-lous adenomas,and CRC(P<0.05),and correlated with adenoma size.It was also associated with CRC metastasis and shorter survival(P<0.05).Furthermore,the expressions of B7-H3 and CD133 demonstrated a value in the CRC survival prediction model,in the training as well as validation set.Conclusions:The immune regulator B7-H3 and cancer stem cell marker CD133 are associated with poor prognosis in CRC,and their expressions may serve as predictive factors for CRC prognosis.

AIM:This study aimed to explore the mechanism by which Bufei-Yishen formula(BYF)mitigates mitochondrial damage in rats with chronic obstructive pulmonary disease(COPD)by regulating the AMPK/PGC-1α signal-ing pathway.METHODS:Forty rats were randomly divided into four groups,each containing ten rats each:control group,COPD group,BYF group,and N-acetylcysteine(NAC)group.The COPD model was established through chronic cigarette smoke exposure combined with periodic bacterial inoculations over an eight-week induction phase.During the subsequent eight-week treatment period(i.e.,weeks 9～16),rats in the control and COPD groups received an isovolumet-ric saline solution via oral gavage,at a standardized daily dose of 2 mL per animal.Moreover,rats in the BYF and NAC groups were given Bufei Yishen formula(11.61 g·kg-1·d-1)or N-acetylcysteine(54 mg·kg-1·d-1)by gavage,once per day.At week 16,samples were collected and the general condition of the rats was observed.Body weight was recorded weekly.We also obtained data characterizing rat lung function,lung pathology,ATP content,and mitochondrial ultra-structure,as well as the levels of interleukin-6(IL-6),tumor necrosis factor-alpha(TNF-α),interleukin-1β(IL-1β),se-rum transforming growth factor-beta 1(TGF-β1)and the enzymatic activities of mitochondrial electron transport chain complexes I(NADH dehydrogenase)and III(cytochrome c reductase).Finally,we quantified the mRNA and protein lev-els of AMPK and PGC-1α in lung tissue.RESULTS:Compared to the control group,the COPD group exhibited yellow-ish hair color,reduced gloss,slower weight gain,and a disordered respiratory rhythm.We also observed significant de-creases(P<0.01)in pulmonary function tidal volume(TV),minute ventilation(MV),peak expiratory flow(PEF),expi-ratory flow at 50%of tidal volume(EF50),forced vital capacity(FVC),forced expiratory volume in 0.1 s(FEV0.1),and FEV0.1/FVC.Histopathological analysis showed alveolar cavity enlargement,bullous changes in lung morphology,smooth muscle hypertrophy in the tracheal wall,ciliary destroyed,mucosal shrinking and thickening,and a large number of in-flammatory cells gathered around the tube.Moreover,the mean linear intercept(MLI)and bronchial wall thickness(BWt)had both significantly increased(P<0.01).Electron microscopic analysis of the lungs revealed a reduction in the number of mitochondria in alveolar epithelial cells,a swollen and deformed lung morphology overall.We observed that the mitochondrial cristae were broken,dissolved or vacuolated,accompanied by a significant reduction in the number of lamel-lar bodies and lung volume,along with a disordered internal lipid layer structure.Furthermore,some lung samples were vacuolated or had content leakage.Further quantitative analyses showed statistically significant increases(P<0.01)in the levels of serum pro-inflammatory mediators,including IL-6,TNF-α,IL-1β,and TGF-β1.At the same time we observed substantial reductions in the enzymatic activities of mitochondrial electron transport chain complexes I and III(P<0.01).Moreover,we found that metabolic impairment correlated with significantly attenuated ATP production(P<0.01)in exper-imental subjects.Moreover,the expression levels of AMPK and PGC-1α mRNA and proteins in lung tissue were signifi-cantly decreased(P<0.01).Moreover,compared to the COPD group,the BYF group showed significant improvements in several of the above indicators,albeit to different degrees(P<0.01 or P<0.05).Moreover,BYF was more effective than NAC in improving minute ventilation and up-regulating PGC-1α expression(P<0.05).CONCLUSION:Bufei-Yishen formula may ameliorate mitochondrial damage in rats with chronic obstructive pulmonary disease by regulating the AMPK/PGC-1α signaling pathway.

Objective:To investigate the relationship between serum soluble CD155 (sCD155), soluble CD163 (sCD163) and chemotherapy efficacy and prognosis in patients with diffuse large B-cell lymphoma (DLBCL).Methods:A total of 126 patients with DLBCL admitted to Handan Central Hospital from May 2018 to May 2020 (DLBCL group) and 126 healthy subjects (control group) were prospectively selected to compare serum sCD155 and sCD163 levels. According to the chemotherapy effect of DLBCL patients, they were divided into effective group and ineffective group, and the serum sCD155 and sCD163 levels were compared before and after treatment. The effective rate of chemotherapy in patients with different serum sCD155 and sCD163 levels was compared. Kaplan-Meier method was used to analyze the relationship between serum sCD155 and sCD163 levels and 3-year overall survival (OS) and progression-free survival (PFS) of DLBCL patients. Cox proportional risk regression model was used to analyze the prognostic factors of DLBCL patients.Results:The serum levels of sCD155 and sCD163 in DLBCL group were higher than those in control group before treatment (all P<0.05). The effective rate of chemotherapy in 126 DLBCL patients in this group was 69.8%(88/126). Compared with the effective group, the serum levels of sCD155 and sCD163 were higher in the ineffective group before and after treatment (all P<0.05). Compared with before treatment, serum sCD155 and sCD163 levels in the effective group were decreased after treatment (all P<0.05). The effective rate of DLBCL patients in sCD155 and sCD163 high level groups was lower than that in sCD155 and sCD163 low level groups (all P<0.05). Kaplan-Meier analysis showed that the 3-year OS and PFS of DLBCL patients in the low level group of sCD155 and sCD163 were higher than those in the high level group (all P<0.05). The high level of sCD155 and sCD163 were independent risk factors for 3-year PFS and OS in DLBCL patients (all P<0.05). Conclusions:Abnormal levels of serum sCD155 and sCD163 in DLBCL patients may reduce the efficacy of chemotherapy and lead to poor prognosis.

A triple-transgenic (tyrosine hydroxylase/dopamine decarboxylase/GTP cyclohydrolase 1, TH/DDC/GCH1) bone marrow mesenchymal stem cell line (BMSCs) capable of stably synthesizing dopamine (DA) transmitters were established to provide experimental evidence for the clinical treatment of Parkinson's disease (PD) by using this cell line. The DA-BMSCs cell line that could stably synthesize and secrete DA transmitters was established by using the triple transgenic recombinant lentivirus. The triple transgenes (TH/DDC/GCH1) expression in DA-BMSCs was detected using reverse transcription-polymerase chain reaction (RT-PCR), Western blotting, and immunofluorescence. Moreover, the secretion of DA was tested by enzyme-linked immunosorbent assay (ELISA) and high-performance liquid chromatography (HPLC). Chromosome G-banding analysis was used to detect the genetic stability of DA-BMSCs. Subsequently, the DA-BMSCs were stereotactically transplanted into the right medial forebrain bundle (MFB) of Parkinson's rat models to detect their survival and differentiation in the intracerebral microenvironment of PD rats. Apomorphine (APO)-induced rotation test was used to detect the improvement of motor dysfunction in PD rat models with cell transplantation. The TH, DDC and GCH1 were expressed stably and efficiently in the DA-BMSCs cell line, but not expressed in the normal rat BMSCs. The concentration of DA in the cell culture supernatant of the triple transgenic group (DA-BMSCs) and the LV-TH group was extremely significantly higher than that of the standard BMSCs control group (P < 0.000 1). After passage, DA-BMSCs stably produced DA. Karyotype G-banding analysis showed that the vast majority of DA-BMSCs maintained normal diploid karyotypes (94.5%). Moreover, after 4 weeks of transplantation into the brain of PD rats, DA-BMSCs significantly improved the movement disorder of PD rat models, survived in a large amount in the brain microenvironment, differentiated into TH-positive and GFAP-positive cells, and upregulated the DA level in the injured area of the brain. The triple-transgenic DA-BMSCs cell line that stably produced DA, survived in large numbers, and differentiated in the rat brain was successfully established, laying a foundation for the treatment of PD using engineered culture and transplantation of DA-BMSCs.

Spinal cord injury (SCI) causes motor, sensory, and autonomic dysfunctions. The gut microbiome has an important role in SCI, while short-chain fatty acids (SCFAs) are one of the main bioactive mediators of microbiota. In the present study, we explored the effects of oral administration of exogenous SCFAs on the recovery of locomotor function and tissue repair in SCI. Allen's method was utilized to establish an SCI model in Sprague-Dawley (SD) rats. The animals received water containing a mixture of 150 mmol/L SCFAs after SCI. After 21 d of treatment, the Basso, Beattie, and Bresnahan (BBB) score increased, the regularity index improved, and the base of support (BOS) value declined. Spinal cord tissue inflammatory infiltration was alleviated, the spinal cord necrosis cavity was reduced, and the numbers of motor neurons and Nissl bodies were elevated. Enzyme-linked immunosorbent assay (ELISA), real-time quantitative polymerase chain reaction (qPCR), and immunohistochemistry assay revealed that the expression of interleukin (IL)‍-10 increased and that of IL-17 decreased in the spinal cord. SCFAs promoted gut homeostasis, induced intestinal T cells to shift toward an anti-inflammatory phenotype, and promoted regulatory T (Treg) cells to secrete IL-10, affecting Treg cells and IL-17⁺ γδ T cells in the spinal cord. Furthermore, we observed that Treg cells migrated from the gut to the spinal cord region after SCI. The above findings confirm that SCFAs can regulate Treg cells in the gut and affect the balance of Treg and IL-17⁺ γδ T cells in the spinal cord, which inhibits the inflammatory response and promotes the motor function in SCI rats. Our findings suggest that there is a relationship among gut, spinal cord, and immune cells, and the "gut-spinal cord-immune" axis may be one of the mechanisms regulating neural repair after SCI.
