Objective To investigate the effects of raddeanin A(RA)on the proliferation and apoptosis of HCT116 cells and on the β-catenin/c-Myc pathway.Methods Human colon cancer HCT116 cells were divided into four groups:Control group,experimental-L group,experimental-M group and experimental-H group.Experimental-L,experimental-M,experimental-H groups were treated with 5,10 and 20 μmol·L-1raddeanin A,and the control group was given the same amount of normal saline,respectively.The inhibitory effect of RA on the proliferation of HCT116 cells of colon cancer was detected by cell counting kit-8(CCK-8)method.Cell nucleus morphology change was observed with the fluorescence;the apoptosis rate was detected by flow cytometry;and the expression of related proteins of β-catenin/c-Myc signaling pathway was detected by western blot.Results After 48 h,the cell inhibitory rates of the control group,experimental-L,experimental-M,experimental-H groups were 0,(19.15±0.65)％,(35.11±0.40)％and(49.93±1.13)％,respectively;the cell apoptosis rates were(0.16±0.18)％,(9.26±0.42)％,(17.87±2.54)％and(38.10±2.70)％,respectively;the protein expression levels of β-catenin were 0.74±0.03,0.69±0.01,0.33±0.02 and 0.16±0.04,respectively;the protein expression levels of c-Myc were 0.89±0.01,0.54±0.03,0.29±0.03 and 0.13±0.04,respectively;the protein expression levels of Cyclin D1 were 0.84±0.04,0.66±0.01,0.48±0.06 and 0.21±0.03,respectively;the expression levels of Cleaved-Caspase3 protein were 0.19±0.03,0.26±0.04,0.45±0.04 and 0.78±0.01,respectively.The above indicators in the experimental-L,experimental-M,experimental-H groups showed statistically significant differences compared to those of control group(all P＜0.05).Conclusion RA can inhibit the proliferation of HCT116 cells and induce apoptosis,which may be related to the inhibition of β-catenin/c-Myc signaling pathway.

Objective To investigate the effect of Jichuan decoction on defecation in rats with slow transit constipation(STC).Methods A total of 36 SD rats were divided into model group,experimental group and control group.Except the control group,STC rat models were established in the other two groups by gavage of 2％rhein acid suspension.The experimental group was given 170％Jichuan decoction of 10 mL·kg-1 by gavage,while the control group and model group were given with 0.9％NaCl by gavage,once a day for 30 days.Fecal dry-wet weight ratio and colon transport time were observed by fecal weighing and recording of first fecal discharge time;substance P(SP)and vasoactive peptide(VIP)contents in plasma were detected by kit;changes in intestinal flora were detected by real-time fluorescent quantitative polymerase chain reaction(qRT-PCR).Results The dry-wet ratio of feces in control group,model group and experimental group were(44.86±4.40)％,(53.44±3.52)％and(44.28±4.33)％,respectively;the colon transport time were(340.17±34.91),(424.67±37.26)and(377.36±38.87)min,respectively;plasma SP were(79.86±7.56),(60.30±2.41)and(78.84±5.83)pg·mL-1,respectively;plasma VIP were(30.56±2.87),(23.38±6.62)and(28.39±2.37)pg·mL-1,respectively;the numbers of Bifidobacterium were 7.77±0.04,5.19±0.09 and 7.45±0.03,respectively;the numbers of Lactobacillus were 6.40±0.07,4.10±0.05 and 6.36±0.08,respectively.There were statistically significant differences in the above indexes between model group and control group,and between experimental group and model group(P＜0.01,P＜0.05).Conclusion Jichuan decoction can improve the defecation of rats with slow transit constipation.

Objective To observe clinical outcomes of propofol and remazolam in patients undergoing elective painless fiberoptic bronchoscopic biopsy.Methods Patients who underwent painless fibreoptic bronchoscopic biopsy in our hospital from March 2022 to April 2023 were selected for the study and divided into 2 groups using simple randomisation method.In the control group,anaesthesia was induced with 1 mg·kg-1 propofol,3 μg·kg-1 fentanyl,0.1 mg·kg-1 cis-atracurium,and anaesthesia was maintained with 4-6 mg·kg-1·h-1 propofol.In the treatment group,anaesthesia was induced with 0.2 mg·kg-1 remazolam,3 μg·kg-1 fentanyl,0.1 mg·kg-1 cis-atracurium,and anaesthesia was maintained with 0.2-0.4 mg·kg-1·h-1 remazolam.We compared the awakening time,laryngeal mask removal time,microscopy time,and the proportion of additional anaesthetics in the 2 groups,and detected the levels of S100β,neuron-specific enolase(NSE),interleukin-6(IL-6),tumour necrosis factor-alpha(TNF-α)in the 2 groups preoperatively and at 24 h postoperatively,and statistically counted the occurrences of adverse reactions in the 2 groups.Results The time for pulling out the laryngeal mask in the treatment group was significantly lower than that in the control group,while the time for microscopy,time for awakening,and proportion of additional anaesthesia drugs were not statistically significant when compared with that in the control group(all P＞0.05).The overall anaesthesia effect grading of the test group was not statistically significant when compared with the control group(P＞0.05).S100β were(0.66±0.17)and(0.78±0.21)μg·L-1;NSE were(8.47±1.78)and(11.47±2.06)μg·L-1;IL-6 were(8.64±1.21)and(12.89±1.47)pg·mL-1;TNF-α were(6.27±1.07)and(9.13±1.41)pg·mL-1,respectively,which were higher than that of preoperative period,and the treatment group was lower than that of the control group at 24 h postoperatively,and the difference was statistically significant(all P＜0.05).The incidence of adverse drug reactions in the treatment group and the control group were 13.75％and 22.50％,respectively,and the difference was not statistically significant(P＞0.05).Conclusion The use of remazolam in painless fiberoptic bronchoscopic biopsy is less neurologically damaging,stabilizes hemodynamics.

Liposome was used as carrier to carry triptolide and ginsenoside Rg3 in the treatment of pancreatic cancer tumor mice. The effects of liposome on the levels of CD4⁺ and CD8⁺ microenvironmental immune factors of pancreatic cancer tumor were investigated, and the tumor inhibitory effect and safety were evaluated. In this study, Pan02 cells were used to construct a tumor-bearing C57BL/6 mouse model. After 14 days of treatment, the changes in tumor volume and body weight of tumor-bearing mice were observed. The results showed that the high and low doses of liposome had significant therapeutic effect on tumor volume in the model group (P < 0.01), and the tumor inhibition rate of high doses of liposome was significantly increased compared with triptolide group (P < 0.05). Immunohistochemistry showed that compared with the model group, the tumor inhibition rate of liposome was significantly increased. The high-dose liposome group can up-regulate the ratio of immune factor CD4⁺/CD8⁺, inhibit the expression of tumor proliferation factor and promote the expression of tumor apoptosis factor, and has a high safety after pathological hematoxylin and eosin staining of liver, spleen, lung and kidney and serum factor detection. Animal welfare and experimental procedures are in accordance with the regulations of the Experimental Animal Ethics Committee of Henan University of Chinese Medicine (approval No.: DWLL202103173). This study provides a new idea for the exploration of immunotherapy for pancreatic cancer.

Objective:To investigate the prognosis of patients with initially resectable gastric cancer liver metastasis (GCLM) who were treated by different modalities, and analyze the influencing factors for prognosis of patients.Methods:The retrospective cohort study was conducted. The clinicopathological data of 327 patients with initially resectable GCLM who were included in the database of a nationwide multicenter retrospective cohort study on GCLM based on real-world data from January 2010 to December 2019 were collected. There were 267 males and 60 females, aged 61(54,68)years. According to the specific situations of patients, treatment modalities included radical surgery combined with systemic treatment, palliative surgery combined with systemic treatment, and systemic treatment alone. Observation indicators: (1) clinical characteristics of patients who were treated by different modalities; (2) prognostic outcomes of patients who were treated by different modalities; (3) analysis of influencing factors for prognosis of patients with initially resectable GCLM; (4) screening of potential beneficiaries in patients who were treated by radical surgery plus systemic treatment and patients who were treated by palliative surgery plus systemic treatment. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the independent sample t test. Measurement data with skewed distribution were represented as M( Q1, Q3), and comparison between groups was conducted using the rank sum test. Count data were described as absolute numbers or percentages, and comparison between groups was conducted using the chi-square test. The Kaplan-Meier method was used to calculate survival rate and draw survival curve, and Log-Rank test was used for survival analysis. Univariate and multivariate analyses were conducted using the COX proportional hazard regression model. The propensity score matching was employed by the 1:1 nearest neighbor matching method with a caliper value of 0.1. The forest plots were utilized to evaluate potential benefits of diverse surgical combined with systemic treatments within the population. Results:(1) Clinical characteristics of patients who were treated by different modalities. Of 327 patients, there were 118 cases undergoing radical surgery plus systemic treatment, 164 cases undergoing palliative surgery plus systemic treatment, and 45 cases undergoing systemic treatment alone. There were significant differences in smoking, drinking, site of primary gastric tumor, diameter of primary gastric tumor, site of liver metastasis, and metastatic interval among the three groups of patients ( P<0.05). (2) Prognostic outcomes of patients who were treated by different modalities. The median overall survival time of the 327 pati-ents was 19.9 months (95% confidence interval as 14.9-24.9 months), with 1-, 3-year overall survival rate of 61.3%, 32.7%, respectively. The 1-year overall survival rates of patients undergoing radical surgery plus systemic treatment, palliative surgery plus systemic treatment and systemic treatment alone were 68.3%, 63.1%, 30.6%, and the 3-year overall survival rates were 41.1%, 29.9%, 11.9%, showing a significant difference in overall survival rate among the three groups of patients ( χ2=19.46, P<0.05). Results of further analysis showed that there was a significant difference in overall survival rate between patients undergoing radical surgery plus systemic treatment and patients undergoing systemic treatment alone ( hazard ratio=0.40, 95% confidence interval as 0.26-0.61, P<0.05), between patients undergoing palliative surgery plus systemic treatment and patients under-going systemic treatment alone ( hazard ratio=0.47, 95% confidence interval as 0.32-0.71, P<0.05). (3) Analysis of influencing factors for prognosis of patients with initially resectable GCLM. Results of multivariate analysis showed that the larger primary gastric tumor, poorly differentiated tumor, larger liver metastasis, multiple hepatic metastases were independent risk factors for prognosis of patients with initially resectable GCLM ( hazard ratio=1.20, 1.70, 1.20, 2.06, 95% confidence interval as 1.14-1.27, 1.25-2.31, 1.04-1.42, 1.45-2.92, P<0.05) and immunotherapy or targeted therapy, the treatment modality of radical or palliative surgery plus systemic therapy were independent protective factors for prognosis of patients with initially resectable GCLM ( hazard ratio=0.60, 0.39, 0.46, 95% confidence interval as 0.42-0.87, 0.25-0.60, 0.30-0.70, P<0.05). (4) Screening of potentinal beneficiaries in patients who were treated by radical surgery plus systemic treatment and patients who were treated by palliative surgery plus systemic treatment. Results of forest plots analysis showed that for patients with high-moderate differentiated GCLM and patients with liver metastasis located in the left liver, the overall survival rate of patients undergoing radical surgery plus systemic treatment was better than patients undergoing palliative surgery plus systemic treatment ( hazard ratio=0.21, 0.42, 95% confidence interval as 0.09-0.48, 0.23-0.78, P<0.05). Conclusions:Compared to systemic therapy alone, both radical and palliative surgery plus systemic therapy can improve the pro-gnosis of patients with initially resectable GCLM. The larger primary gastric tumor, poorly differen-tiated tumor, larger liver metastasis, multiple hepatic metastases are independent risk factors for prognosis of patients with initial resectable GCLM and immunotherapy or targeted therapy, the treatment modality of radical or palliative surgery plus systemic therapy are independent protective factors for prognosis of patients with initially resectable GCLM.

Objective To explore the expression of serum miR-410-3p in patients with rheumatoid arthritis(RA)and its relationship with knee soft tissue lesions.Methods A total of 89 RA patients admitted to our hospital were selected and divided into the active group(42 cases)and the remission group(47 cases)according to disease activity score in 28 joints(DAS28).In addition,52 healthy volunteers underwent physical examination during the same period in our hospital were selected as the healthy group.The expression level of serum miR-410-3p was detected by RT-PCR,the lesions of knee soft tissue was examined by ultrasound,and the relationship between the expression of serum miR-410-3p and knee soft tissue lesions was analyzed by Pearson.Results The expression levels of serum miR-410-3p of patients in the active group and the remission group were lower than that in the healthy group(P<0.05),and the expression level of serum miR-410-3p of patients in the active group was lower than that in the remission group(P<0.05).The cartilage thicknesses of medial and lateral ankle of patients in the active group and the remission group were smaller than those in the healthy group(P<0.05),and the above indexes in the active group were smaller than those in the remission group(P<0.05).The depths of suprapatellar bursa fluid and synovial thicknesses of patients in the active group and the remission group were greater than those in the healthy group(P<0.05),and the depth of suprapatellar bursa fluid and synovial thickness of patients in the active group were greater than those in the remission group(P<0.05).The level of serum miR-410-3p in RA patients was positively correlated with the depth of suprapatellar bursa fluid and synovial thickness(P<0.05),and negatively correlated with the cartilage thicknesses of medial and lateral ankle(P<0.05).Conclusion Serum miR-410-3p expression level in RA patients is decreased,which was closely related to knee soft tissue lesions,detecting the changes of serum miR-410-3p level may provide a reference for the evaluation of knee soft tissue lesions.

Objective To investigate the effects of acetylshikonin on proliferation,invasion and migration of oxaliplatin-resistant human colon cancer HCT116 cells(HCT116/L-OHP).Methods HCT116/L-OHP cells were divided into blank group,control group,experimental-L group,experimental-M group and experimental-H group.The control group was treated with 10 μmol·L-1 oxaliplatin.The experimental-L,experimental-M,experimental-H groups were treated with 1.25,2.50 and 5.00 μmol·L-1 acetylshikin and 10 μmol·L-1 oxaliplatin,respectively.The blank group was given routine culture.The changes of HCT116/L-OHP cell proliferation were detected by cell counting kit-8(CCK-8)method;flow cytometry was used to evaluate the apoptosis of cells;Transwell assay was used to detect the changes of cell migration and invasion ability;Western blot was used to detect the expressions of P-glycoprotein(P-gp),matrix metallo-proteinases 2(MMP2),nuclear factor kappa-B(NF-κB)/and hypoxia induced factor-1 α(HIF-1α)proteins.Results The cell inhibition rates of the blank group,control group and experimental-L,-M,-H groups were 0,(8.27±0.01)％,(10.53±0.02)％,(34.17±0.01)％and(48.47±0.05)％;cell apoptosis rates were(0.13±0.02)％,(1.37±1.04)％,(9.73±0.87)％,(26.71±4.26)％and(40.75±4.70)％;invading cells were 130.70±9.81,127.10±9.21,71.83±3.57,28.83±1.87 and 19.63±6.11;the number of migration cells was 150.50±10.17,148.40±8.13,94.58±4.09,63.98±5.09 and 31.85±5.50;the relative expression levels of P-gp protein were 0.91±0.01,0.89±0.02,0.75±0.04,0.61±0.07 and 0.25±0.03;the relative expression levels of MMP2 protein were 1.24±0.01,1.22±0.02,0.96±0.01,0.53±0.01 and 0.16±0.02;the relative expression levels of NF-κB-p65 were 1.12±0.12,1.07±0.01,0.78±0.01,0.64±0.02 and 0.31±0.03;the relative expression levels of HIF-1 α were 0.65±0.04,0.52±0.03,0.41±0.02,0.35±0.03 and 0.09±0.01,respectively.The above indicators in the experimental-L,-M,-H groups showed statistically significant differences compared to those of blank group(all P＜0.05).Conclusion Acetylshikonin combined with oxaliplatin can significantly inhibit the proliferation,invasion and migration of HCT116/L-OHP cells,and induce cell apoptosis,which may be related to the inhibition of P-gp and MMP2 expression and the activation of NF-κB/HIF-1 α signal.

Objective:To examine the impact of varied surgical treatment strategies on the prognosis of patients with initial resectable gastric cancer liver metastases (IR-GCLM).Methods:This is a retrospective cohort study. Employing a retrospective cohort design, the study selected clinicopathological data from the national multi-center retrospective cohort study database, focusing on 282 patients with IR-GCLM who underwent surgical intervention between January 2010 and December 2019. There were 231 males and 51 males, aging ( M(IQR)) 61 (14) years (range: 27 to 80 years). These patients were stratified into radical and palliative treatment groups based on treatment decisions. Survival curves were generated using the Kaplan-Meier method and distinctions in survival rates were assessed using the Log-rank test. The Cox risk regression model evaluated HR for various factors, controlling for confounders through multivariate analysis to comprehensively evaluate the influence of surgery on the prognosis of IR-GCLM patients. A restricted cubic spline Cox proportional hazard model assessed and delineated intricate associations between measured variables and prognosis. At the same time, the X-tile served as an auxiliary tool to identify critical thresholds in the survival analysis for IR-GCLM patients. Subgroup analysis was then conducted to identify potential beneficiary populations in different surgical treatments. Results:(1) The radical group comprised 118 patients, all undergoing R0 resection or local physical therapy of primary and metastatic lesions. The palliative group comprised 164 patients, with 52 cases undergoing palliative resections for gastric primary tumors and liver metastases, 56 cases undergoing radical resections for gastric primary tumors only, 45 cases undergoing palliative resections for gastric primary tumors, and 11 cases receiving palliative treatments for liver metastases. A statistically significant distinction was observed between the groups regarding the site and the number of liver metastases (both P<0.05). (2) The median overall survival (OS) of the 282 patients was 22.7 months (95% CI: 17.8 to 27.6 months), with 1-year and 3-year OS rates were 65.4% and 35.6%, respectively. The 1-year OS rates for patients in the radical surgical group and palliative surgical group were 68.3% and 63.1%, while the corresponding 3-year OS rates were 42.2% and 29.9%, respectively. A comparison of OS between the two groups showed no statistically significant difference ( P=0.254). Further analysis indicated that patients undergoing palliative gastric cancer resection alone had a significantly worse prognosis compared to other surgical options ( HR=1.98, 95% CI: 1.21 to 3.24, P=0.006). (3) The size of the primary gastric tumor significantly influenced the patients′ prognosis ( HR=2.01, 95% CI: 1.45 to 2.79, P<0.01), with HR showing a progressively increasing trend as tumor size increased. (4) Subgroup analysis indicates that radical treatment may be more effective compared to palliative treatment in the following specific cases: well/moderately differentiated tumors ( HR=2.84, 95% CI 1.49 to 5.41, P=0.001), and patients with liver metastases located in the left lobe of the liver ( HR=2.06, 95% CI 1.19 to 3.57, P=0.010). Conclusions:In patients with IR-GCLM, radical surgery did not produce a significant improvement in the overall prognosis compared to palliative surgery. However, within specific patient subgroups (well/moderately differentiated tumors, and patients with liver metastases located in the left lobe of the liver), radical treatment can significantly improve prognosis compared to palliative approaches.

Objective To provide anatomical,radiological,and clinical diagnostic and therapeutic references for ankylosing spondylitis and spinal surgical operations.Methods Non-measurement spinal observations,X-ray examinations,and measurements were performed on two spinal specimens,along with digital image acquisition and processing.Results The first specimen included thoracic vertebra 7(T7)to lumbar vertebra 3(L3),with an average total length of 29.7 cm;the second specimen ranged from cervical vertebra 7(C7)to lumbar vertebra 2(L2),with an average total length of 38.3 cm.The specimens showed partial or complete calcification of ligaments,ossification of the small joints and intervertebral discs,and osteoporosis;The anterior-posterior diameter(width)of the vertebral foramen was narrower than that of a normal adult,while most of the superior-inferior diameter(height)was wider.Radiographically,the anterior longitudinal ligament calcification appeared as dot-like or striated,but it was actually flaky in the actual specimens.The specimens provided views of the facet joints,costovertebral joints,and intervertebral foramina that was difficult to demonstrate on two-dimensional X-ray images.Conclusion As ankylosing spondylitis progresses,the range of motion in spinal bending and rotation decreases,as does the extent of thoracic expansion,thereby affecting respiration and complicating procedures such as intraspinal anesthesia and sacral canal injections.In terms of diagnosis,bone specimens and X-ray films allow us to understand the development process and severity of ankylosing spondylitis more directly and accurately.
