OBJECTIVE To investigate the effect and mechanism of Jingangteng capsules in the treatment of non-alcoholic fatty liver disease （NAFLD）. METHODS Thirty-two SD rats were randomly divided into normal group and modeling group. The modeling group was fed a high-fat diet to establish a NAFLD model. The successfully modeled rats were then randomly divided into model group， atorvastatin group[positive control， 2 mg/（kg·d）]， and Jingangteng capsules low- and high-dose groups [0.63 and 2.52 mg/（kg·d）]， with 6 rats in each group. The pathological changes of the liver were observed by hematoxylin-eosin staining and oil red O staining. Enzyme-linked immunosorbent assay was performed to determine the serum levels of triglycerides （TG）， total cholesterol （TC）， high-density lipoprotein cholesterol （HDL-C）， low-density lipoprotein cholesterol （LDL-C）， alanine transaminase （ALT）， aspartate transaminase （AST）， tumour necrosis factor-α （TNF-α）， interleukin-1β （IL-1β）， IL-6， IL-18. 16S rDNA amplicon sequencing and metabolomics techniques were applied to explore the effects of Jingangteng capsules on gut microbiota and metabolisms in NAFLD rats. Based on the E-mail：591146765@qq.com metabolomics results， Western blot analysis was performed to detect proteins related to the nuclear factor kappa-B （NF-κB）/NOD-like receptor family protein 3 （NLRP3） signaling pathway in the livers of NAFLD rats. RESULTS The experimental results showed that Jingangteng capsules could significantly reduce the serum levels of TG， TC， LDL-C， AST， ALT， TNF-α， IL-1β， IL-6， IL-18， while increased the level of HDL-C， and alleviated the hepatic cellular steatosis and inflammatory infiltration in NAFLD rats. They could regulate the gut microbiota disorders in NAFLD rats， significantly increased the relative abundance of Romboutsia and Oscillospira， and significantly decreased the relative abundance of Blautia （P＜0.05）. They also regulated metabolic disorders primarily by affecting secondary bile acid biosynthesis， fatty acid degradation， O-antigen nucleotide sugar biosynthesis， etc. Results of Western blot assay showed that they significantly reduced the phosphorylation levels of NF-κB p65 and NF-κB inhibitor α， and the protein expression levels of NLRP3， caspase-1 and ASC （P＜0.05 or P＜0.01）. CONCLUSIONS Jingangteng capsules could improve inflammation， lipid accumulation and liver injury in NAFLD rats， regulate the disorders of gut microbiota and metabolisms， and inhibit NF-κB/NLRP3 signaling pathway. Their therapeutic effects against NAFLD are mediated through the inhibition of the NF-κB/NLRP3 signaling pathway.

Objective To evaluate the value of postoperative radiotherapy (PORT) in patients with stage ⅢA-N2 non-small cell lung cancer who received complete resection and chemotherapy. Methods Patients with stage ⅢA-N2 non-small cell lung cancer who received complete resection and chemotherapy were chosen from the SEER Research Plus Database [17 Registries, November 2012 Submission (2000-2019)]. The patients were divided into a PORT group and a non-PORT group according to whether the PORT was used. To balance baseline characteristics between non-PORT and PORT groups, R software was used to conduct a propensity score matching (PSM) with a ratio of 1 : 1 and a matching tolerance of 0.01. Both the Cox regression analysis and Kaplan-Meier survival analysis were conducted to evaluate the value of PORT in terms of overall survival (OS) and disease-specific survival (DSS). Results In total, 2468 patients with stage ⅢA-N2 non-small cell lung cancer were enrolled, including 1078 males and 1390 females with a median age of 65 (58-71) years. There were 1336 patients in the PORT group, and 1132 patients in the non-PORT group. Cox regression analysis showed that PORT was not significantly associated with OS (multivariate analysis: HR=1.051, 95%CI 0.949-1.164, P=0.338) and DSS (multivariate analysis: HR=1.094, 95%CI 0.976-1.225, P=0.123). No statistical difference was found in the OS or DSS between non-PORT group and PORT group after PSM analysis (P＞0.05). Conclusion PORT does not have a survival benefit for patients with stage ⅢA-N2 non-small cell lung cancer who received complete resection and chemotherapy.

ObjectiveTo explore the potential therapeutic targets and molecular mechanisms of menstrual blood-derived stem cells (MenSCs) transplantation combined with exercise training in promoting recovery in rats with spinal cord injury (SCI) through transcriptome sequencing analysis. MethodsFemale SD rats aged two months were selected and a SCI model was established by a hemisection at the tenth thoracic vertebra (T10). The rats were then divided into two groups: the Cell and Treadmill Training (CTMT) group, which received MenSCs transplantation and treadmill training after SCI, and the SCI group (control), with 12 rats in each group. One week after modeling, the CTMT group received a microinjection of 1×10⁵ MenSCs at the injury site, followed by two weeks of weight-supported aerobic exercise training. Spinal cord tissue from the injury site was selected for transcriptome sequencing, and mRNA expression data from both the SCI and CTMT groups were analyzed. Differential gene expression, GO (Gene Ontology) functional enrichment, KEGG (Kyoto Encyclopedia of Genes and Genomes) pathway enrichment, and protein-protein interaction (PPI) network analyses were performed. Motor function recovery was assessed using the Basso, Beattie, and Bresnahan (BBB) score, while histopathological changes at the injury site were evaluated through hematoxylin-eosin (HE) staining. Real-time fluorescent quantitative PCR and Western blotting were used to verify the expression of differentially expressed genes. ResultsTranscriptome sequencing analysis showed 247 upregulated genes and 174 downregulated genes in the CTMT group compared to the SCI group. Notably, genes such as Bdnf, Hmox1, Sd4, Mmp3, and Cd163 were significantly upregulated [|log2(FoldChange)|≥0.66, P<0.05]. KEGG pathway enrichment analysis and GO functional enrichment analysis indicated that these differentially expressed genes were mainly involved in growth and development, metabolic reactions, and immune-inflammatory processes, such as axon growth and the electron transport chain. The Bdnf gene was notably enriched in the PI3K-Akt signaling pathway. The BBB score showed that MenSCs transplantation combined with exercise training significantly improved the motor function of SCI rats. HE staining revealed that pathological changes at the injury site were significantly reduced in the treatment group. Furthermore, real-time quantitative PCR and Western blotting confirmed that brain-derived neurotrophic factor (BDNF) mRNA and protein expression levels in the CTMT group were significantly higher than those in the SCI group (P<0.001). ConclusionThe combined exercise training with MenSCs effectively promotes the recovery of motor function in SCI rats by upregulating BDNF expression, providing a novel strategy for SCI treatment.

Objective:To investigate the efficacy and safety of humanized CD19-specific chimeric antigen receptor T cells (hCART19s) in treating children and young adults with relapsed/refractory acute lymphoblastic leukemia (R/R ALL) and to analyze relevant factors affecting its curative effect and prognosis.Methods:We conducted a single-center clinical trial involving 31 children and young adult patients with R/R B-ALL who were treated with humanized CD19-specific CAR-T cells (hCART19s) from May 2016 to September 2021.Results:Results showed that 27 (87.1%) patients achieved complete remission (CR) or CR with incomplete count recovery (CRi) one month after CAR-T cell infusion. During treatment, 20 (64.5%) patients developed grade 1-2 cytokine release syndrome (CRS) , and 4 (12.9%) developed grade 3 CRS. Additionally, two patients had grade 1 neurological events. During the follow-up with a median time of 19.3 months, the median event-free survival (EFS) was 15.7 months (95% CI 8.7-22.5) , and the median overall survival (OS) was 32.2 months (95% CI 10.6-53.9) . EFS and OS rates were higher in patients who have undergone hemopoietic stem cell transplantation (HSCT) than in those without [EFS: (75.0 ± 12.5) % vs (21.1 ± 9.4) %, P=0.012; OS: (75.0 ± 12.5) % vs (24.6 ± 10.2) %, P=0.035]. The EFS and OS rates were significantly lower in patients with >3 treatment lines than in those with <3 treatment lines [EFS: 0 vs (49.5±10.4) %, P<0.001; OS: 0 vs (52.0±10.8) %, P<0.001]. To the cutoff date, 12 patients presented with CD19 + relapse, and 1 had CD19 - relapse. Conclusion:hCART19s are effective in treating pediatric and young adult R/R ALL patients, with a low incidence of severe adverse events and reversible symptoms. Following HSCT, the number of treatment lines can affect the long-term efficacy and prognosis of pediatric and young adult R/R ALL patients.

Methods 75 parturients who were presenting for elective cesarean section were randomly divided into pregestational diabetes mellitus group (group P, n=15) , gestational diabetes mellitus group (group G, n=30) and non-diabetic parturients group (group N, n=30). After entering the operating room, parturients were given spinal anesthesia spinal at the L3～4 interspace with 0.5％ hyperbaric ropivacaine 3 ml with left lateral decubitus position. To determine the level of sensory block by 10 g monofilament and evaluate the motor block with modified Bromage score. To record the time T6 sensory level was obtained, the onset time of sensory block, motor block, the duration of the motor block and sensory block. Results The time T6 sensory level was obtained of Group P were significantly shortened (P < 0.001). Compared with Group N and Group G, the duration of sensory (P < 0.001) and motor (P < 0.001) block were significantly prolonged. Conclusion Parturients with pregestational diabetes mellitus are more sensitive to 0.5％ hyperbaric ropivacaine compared to non-diabetic parturients. Compared with non-diabetic parturients, there are no difference in the sensitivity of parturient with gestational diabetes mellitus to 0.5％hyperbaric ropivacaine.

In the paper, in view of complex science, the topological properties of acupoint-symptom network were analyzed quantitatively by taking acupoint as node and indication as the connection, such as high clustering coefficient and the small world effect. It was the first time to give the abstraction for the topological proof of the high efficiency information transmission property of acupoint-symptom network meridian system at different times. Its quantitative and digitalized significance was analyzed on the development of meridian theory under the complex scientific background so as to provide a new thought and method for the study of meridian theory and acupuncture modernization.

Objective To investigate CT signs of peripheral small cell lung cancer (SCLC).Methods The CT signs of 78 patients with SCLC confirmed by pathology were retrospectively reviewed.According to the presence of mediastinal lymph node metastasis and its size, 78 cases of peripheral SCLC were divided into two types: typeⅠ(isolated lesion) and typeⅡ(lung lesion + lymph nodes).Type Ⅱwere divided into two subtypes:type Ⅱa (short diameter of lymph nodes of pulmonary hilar and mediastinum less than 10 mm) and type Ⅱ b (short diameter of lymph nodes of pulmonary hilar and mediastinum greater than or equal to 10 mm).Results Of the 78 SCLCs, typeⅠwas 7 cases, and typeⅡwas 71 cases,including 8 cases of typeⅡa and 63 cases of typeⅡb.All of the lesions were soild density.The shape were round or oval in 52 cases, vermicular or spindlein 9 cases, and other shapes in 17 cases.Among 71 cases performed CT enhancement, there were 9 cases with homogeneous enhancement, 58 cases with heterogeneous enhancement, 4 cases with non-enhancement large necrosis area.These cases showed the following CT signs: smooth edge in 65 cases, coarse edge in 12 cases, blurred edge in 1 case;air bronchogram in 3 cases, vacuole sign in 4 cases, calcification in 4 cases;lobulation sign in 46 cases, spiculated sign in 5 cases;thickening of the bronchovascular bundle in 41 cases, pleural indentation in 6 cases, marginal ground-glass opacity in 5 cases, vascular convergence sign in 1 case;emphysema in 42 cases;obstructive pneumonia in 4 cases;bronchus abruptly interruption on the edge of the nodules in 18 cases;enlargement of mediastinal lymph nodes in 63 cases, the diameter of mediastinal lymph nodes larger than the primary lesions in 42 cases;and a little pleural effusion in 9 cases.Conclusion Solid density, smooth margin with lobulation,and significantly enlarged mediastinal lymph nodes are common signs in peripheral SCLC.Thickening of the bronchovascular bundle indicates reletively advanced stage.

Objective To evaluate multi-slice CT (MSCT) features and pathological basis of lung cancer containing thin-walled airspace. Methods Thirty?five cases of pathologically confirmed lung cancer containing thin-walled airspace were retrospectively analysed with regard to clinical data, pathological types and MSCT features between 2012 and 2015.There were 35 cases(25 adenocarcinoma, 9 squamous carcinoma, 1 spindle cell tumor) in total. MSCT features were compared between the lesions with or without solid component .Fisher exact test was used for the statistical analysis. For dynamic follow-up CT scans, the lesion dynamic change was evaluated .Correlations between the pathological section and CT images of the 11 cases were analysed. Results These features accounted for more than 60% of all MSCT signs in 35 cases, including round shape in 28 cases(80.0%),lobulation in 32 cases(91.4%),multiple cysts in 27 cases(77.1%), irregular inner wall in 33 cases(94.3%)and septum in airspace in 31 cases(88.6%). Shape, spiculation, bronchus cut-off, blood vessel and bronchus passing through the airspace, and ground-glass opacity were significantly different between the lesions with or without solid component(P<0.05).The frequency of spiculation(11 cases) and bronchus cut-off(12 cases) in mixed solid lesions was higher than that in lesions without solid component(1 case, respectively).The frequency of irregular shape(6 cases),blood vessel passing through the airspace(12 cases),ground-glass opacity(13 cases)and bronchus passing through the airspace(7 cases) in lesions without solid were higher than that in solid mixed lesions(1, 1, 5, 3 cases respectively).The pathological basis of the formation of thin-walled airspace was obvious central necrosis in solid lesions and emphysematous change due to the tumor cells diffused along the inner airspace wall and the alveolar wall destruction.Five lesions were with progressive wall thickening and increased size of the airspace,and two lesions were with decreased size of the airspace and enlarged nodules in followed CT.One case of lung cancer with thin-walled airspace evolved from ground glass nodule. Conclusions The CT manifestation of lung cancer containing thin-walled airspace was characteristic.The pathological basis of the thin-walled airspace was various.

Objective To compare the safety and efficacy of the 2μm laser and the bipolar electrotome used in transurethral re-section of bladder tumor(TURBT)for treating non-muscle invasive bladder cancer(NMIBC).Methods The clinical data in the pa-tients with NMIBC treated by TURBT in our hospital from March 2009 to May 2013 were retrospectively analyzed.All patients were divided into the 2μum laser group(n=89)and the bipolar electrotome group(n=82).The operation time,complications,post-operative hospital stay and recurrence rate were compared between the two groups.Results There were no statistically significant differences in the operation time,postoperative hospital stay and recurrence rate between the two groups(P>0.05).Compared with the 2 μm laser group,the bipolar electrotome group showed significantly higher occurrence rate of the obturator nerve reflex (20.7%vs.0,P<0.05)and the bladder perforation(7.3% vs.0,P<0.05)and longer postoperative bladder irrigation time [(3.1±0.9)d vs.(2.2±1.0)d,P<0.05],the differences between the two groups had statistical significance.Conclusion Com-pared with bipolar electrotome,the 2μm laser used in TURBT is safe and effective with few complications for treating NMIBC.
