Objective:To explore the value of 3D reconstruction combined with watershed analysis in thoracoscopic anatomical partial lobectomy for peripheral early stage lung cancer.Methods:A retrospective cohort study was used to analyze the case data of 152 patients with early peripheral lung cancer who received targeted treatment in Hai′an People′s Hospital of Jiangsu Province from January 2022 to April 2023. All patients were treated with thoracoscopic anatomical partial lung resection. According to different preoperative analysis methods, they were divided into an observation group ( n=79) and a control group ( n=73). The observation group underwent three-dimensional reconstruction combined with venous drainage analysis, and the control group underwent routine analyze. The surgical indicators, pulmonary function indicators, C-reactive protein (CRP), interleukin-6 (IL-6) and complications were compared between the two groups. Normally distributed measurement data were expressed as mean±standard deviation ( ± s), independent samples t-test was used for comparison between groups, and paired-sample t-test was used for comparison within groups. Comparison of enumeration data between groups was performed using the chi-square test. Results:The operation time, postoperative drainage time, postoperative hospital stay, and intraoperative blood loss in the observation group were (76.57±11.94) min, (2.15±0.24) d, (4.32±0.75) d, and (27.63±3.54) mL respectively. The control group was (112.64±13.67) min, (3.76±0.31) d, (5.16±0.81) d, (53.26±4.61) mL, respectively. The observation group was smaller than the control group, and the differences between the two groups were statistically significant ( P<0.05). At discharge, the observation group had maximum ventilation per minute as a percentage of predicted value (MVV% pred), forced expiratory volume in 1 second as a percentage of predicted value (FEV1% pred), and forced vital capacity as a percentage of predicted value (FVC% pred) were (83.33±7.51)%, (85.22±7.44)%, (84.16±7.26)%, and those of the control group were (77.19±7.46)%, (76.47±7.36)%, and (79.38±7.20)%, respectively. The observation group was greater than that of the control group, and the differences between the two groups were statistically significant ( P<0.05). The CRP and IL-6 in the observation group were(47.53±6.34) mg/L, (32.21±5.14) mg/L, (144.53±20.84) ng/L, (180.82±21.17) ng/L, respectively on the 1st and 3rd days after surgery, while those in the control group were (57.84±6.71) mg/L, (38.77±5.23)mg/L, (155.14±22.83) ng/L, (200.97±25.52) ng/L, the observation group was lower than that of the control group, and the difference was statistically significant ( P<0.05). The incidence rate of complications in the observation group was 5.06%, and that in the control group was 10.96%, There was no statistically significant difference between the two groups ( P>0.05). Conclusion:Preoperative 3D reconstruction combined with venous drainage analysis can better promote the recovery of patients with early peripheral lung cancer and retain more lung function after thoracoscopic anatomical partial pulmonary resection.

Objective:To investigate the effect and mechanism of Jiedu Xiaoying Patch in rats with Hashimoto's thyroiditis (HT).Methods:Totally 32 rats were randomly divided into a blank group of 8 rats and a model group of 24 rats. The HT rat model was prepared by freely drinking 0.064% sodium iodide solution in the modeling module. 24 successfully modeled rats were randomly divided into model group, selenium yeast group, and patch group, with 8 rats in each group. Starting from the 9th week, the application group applied Jiedu Xiaoying Patch to the surface projection area of the thyroid gland in the neck of rats for 6 hours, once a day, for a total of 6 weeks; the selenium yeast group was orally administered with 21 μg/ml selenium yeast solution at a dose of 0.5 ml/100 g, while the blank group, model group, and patch group were orally administered with equal volumes of physiological saline solution once a day for a total of 6 weeks. The levels of TGAb,TPOAb, Sema 5A, and IL-17A in rat serum were detected by ELISA. The changes of thyroid tissue was observed with HE staining. The relative expression levels of plexin-A1 and plexin-B3 were determined through RT-PCR.Results:Compared with the model group, the levels of TPOAb, TGAb, Sema 5A, and IL-17A decreased ( P<0.05), and the expressions of plexin-A1 and plexin-B3 decreased in the selenium yeast group and the patch group ( P<0.05). The thyroid follicles in the model group were severely damaged, with a large number of lymphocytes infiltrating the interstices; the thyroid follicular structure of the selenium yeast group was relatively intact, and lymphocyte infiltration was reduced compared to the model group. The thyroid follicular structure of the patch group was basically intact, with a small amount of lymphocyte infiltration observed. Conclusion:Jiedu Xiaoying Patch can significantly reduce the levels of TPOAb and TGAb in HT rats. The mechanism may be related to reducing the content of Sema 5A, inhibiting the expressions of receptors plexin-A1 and plexin-B3, reducing the production of inflammatory cytokines such as IL-17A, and inhibiting immune and inflammatory responses.

Oral squamous cell carcinoma is a common malignant tumor of the head and neck.Early surgery can achieve good results,but most patients have cervical lymph node metastasis at the time of initial diagnosis.Although surgery combined with radiotherapy or chemotherapy can delay the progression of the disease,the overall prognosis is still not ideal.Especially in patients at stage Ⅲ/Ⅳ,the long-term survival rate has not improved.As a key microbubble in intercellular communication,exosomes contain a large number of biological molecules such as nucleic acids,proteins and lipids.Tumor-derived exosomes play a key role in regulating the tumor micro-environment.This article reviews the effects of tumor-derived exosomes on tumor proliferation,metastasis,immune regulation,diagnosis and treatment in oral squamous cell carcinoma,in order to provide new ideas for early diagnosis and treatment of oral cancer.

Objective To explore the change of nucleoplasm distribution of glucocorticoid receptor alpha(GRα)in peripheral blood of children with primary nephrotic syndrome(PNS)during the course of the disease,aiming at evaluating the correlation between nuclear transport abnormality and different GC responses.Methods A total of 45 children with PNS were enrolled as subjects in this prospective study,and divided into steroid-sensitive nephrotic syndrome(SSNS,n=36)and steroid-resistant nephrotic syndrome(SRNS,n=9)groups,according to their response to GC.The SSNS group was further subclassified into non-frequently relapsing nephrotic syndrome(NFRNS,n=21)and frequently relapsing nephrotic syndrome(FRNS,n=15)based on relapse frequency during 12-month follow-up.Peripheral blood samples were collected before GC treatment,6-week and 6-month after GC treatment.GRα nuclear localization was detected by immunofluorescence assay,and their correlations with clinical-laboratory indicators were analyzed.Results Before the GC treatment,the average fluorescence intensity showed no significantly difference among different groups(P＞0.05),the GRαin the three groups were localized mainly in cytoplasm,and the nucleocytoplasmic ratio showed no significantly difference among the three groups(P＞0.05).6-week after the GC treatment,the average fluorescence intensity showed no significantly difference among the three groups(P＞0.05),the GRα in SSNS group were localized mainly in nucleus,while those in SRNS group were localized mainly in cytoplasm.Furthermore,nucleocytoplasmic ratio in NFRNS group and SRNS group demonstrated significant differences,while those in NFRNS group and FRNS group showed no significant difference(P＞0.05).6-month after the GC treatment,the average fluorescence intensity in NFRNS group and FRNS group showed no significant difference(P＞0.05),GRα in the two groups were localized mainly in nucleus,and their nucleocytoplasmic ratio had significantly differences(P＜0.05).The GRα nucleocytoplasmic ratio in children with PNS was negatively correlated with 24-hour urine protein(24 h-UTP),TNF-α,while positively correlated with serum albumin(Alb).Conclusion There are differences in nuclear transport ability among PNS children of SRNS,NFRNS and FRNS groups,and these differences are correlated with the differency of GC responses.

Objective: To study the effect of benazepril on the expression of nuclear factor E2 related factor 2 (Nrf2), nicotinamide adenine dinucleotide phosphate oxidase 4 (NOX4) and reactive oxygen species (ROS) concentration in rats with hepatic fibrosis and to explore the possible antifibrotic mechanism of benazepril. Methods: Twenty-two healthy male Sprague-Dawley rats were randomly divided into 3 groups: control group (6 rats), model group (8 rats) and benazepril treatment group (8 rats). Two rats died during modeling and treatment in the model group and the benazepril treatment group, and a model of hepatic fibrosis induced by carbon tetrachloride (CCL₄) was established. The rats in benazepril group were given benazepril for 8 weeks by gastric gavage. The assessment of liver tissue damage in each group was measured using conventional hematoxylin-eosin and Masson staining. The mRNA level of Nrf2, NOX4 in liver tissue was detected by RT-PCR, and serum ROS concentration was determined by colorimetry. All data were expressed in mean ± standard deviations, and were analyzed using SPSS21.0 statistical software. The data were compared using one-way analysis of variance, and the LSD-t method was used for pairwise comparison between the two groups. The correlation analysis was performed by Spearman’s correlation analysis. Results: In the liver of the model group, with the aggravation of liver fibrosis the expression of Nrf2mRNA, NOX4 mRNA and ROS concentration were higher than control group [(4.01 ± 3.40), (31.78 ± 3.96), (1.82 ± 0.46) μg/ ml vs. (0.12 ± 0.11), (2.03 ± 0.31), (1.56±0.84) μg/ml, P < 0.05]. After benazepril treatment, NOX4 mRNA expression and ROS concentration were decreased than the model group [(15.93 ± 5.01), (0.78 ± 0.44) μg/ml vs. (31.78 ± 3.96), (1.82 ± 0.46) μg /ml, P < 0.05], while Nrf2 mRNA expression was higher than the model group [(6.69 ± 4.86) vs. (4.01 ± 3.40), P < 0.05]. There was a positive correlation between Nrf2 and NOX4, Nrf2 and ROS, and NOX4 and ROS (r = 0.616, 0.411, 0.802, P < 0.05). Conclusion Benazepril may exert an anti-hepatic fibrosis effect by activating Nrf2 expression, or may inhibit the ROS-mediated oxidative stress in response to NOX4.

Objective: To investigate the effects of angiotensin II type 1 receptor antagonist valsartan on leptin, leptin receptor and collagen in rats with hepatic fibrosis. Methods: Thirty-six male wistar rats were randomly divided into control group, model group and drug-treated group, with 12 rats in each group. Liver fibrosis models were made by subcutaneous injection of carbon tetrachloride on the dorsal of the rats, simultaneously gastric gavage with Valsartan and were killed at the end of 8th week. The degree of liver fibrosis was observed by HE and Masson staining. The serum leptin (LP) and TGFβ1 were determined by ELISA. Liver LP mRNA and leptin receptor mRNA (OB-R mRNA) were detected by RT-PCR. Liver LP, OB-R and collagen I were detected by Western blot. The data of multiple groups were analyzed by one-way analysis variance (ANOVA), and linear correlation was performed between serum LP and TGF β1. Results: After the intervention of valsartan, HE and Masson staining showed that the degree of liver fibrosis was significantly reduced. The levels of serum LP and TGFβ1 in the control group were (18.92 ± 7.10) ng/ml and (9.13 ± 1.58) pg/ml respectively, which were significantly lower than those in the model group (46.92 ± 28.54) ng/ml and (16.39 ± 3.56) pg/ml, And (29.27 ± 7.27) ng/ml and (12.24 ± 2.94) pg/ml in the drug-treated group, respectively. The F values were 7.864 and 20.057 respectively. The P values were < 0.05. The differences were statistically significant. The relative expression levels of LP and OB-R mRNA in the control group were 0.35 ± 0.18 and 0.62 ± 0.18, respectively, which were significantly lower than those in the model group (1.79 ± 1.79 and 1.52 ± 1.44, and drug-treated group 0.48 ± 0.34 and 0.75 ± 0.26, respectively), F values = 6.914,3.894, P values were < 0.05, the differences were statistically significant. The relative expression levels of LP, OB-R and collaten I in liver were 0.71 ± 0.13, 0.81 ± 0.11 and 0.76 ± 0.13 in the model group, 0.97 ± 0.06, 1.04 ± 0.06, and 1.05 ± 0.04 respectively in the drug-treated group and 0.74 ± 0.05, 0.93 ± 0.05 and 0.91 ± 0.05. The F values were 15.425, 13.757 and 19.130 respectively in three groups (P < 0.001), the difference was statistically significant. Conclusion Valsartan, an angiotensin II type 1 receptor antagonist, can reduce the expression of leptin and leptin receptor, reduce the production of TGFβ1 and collaten I, and play an anti-hepatic fibrosis effect.
