ObjectiveTo investigate the key targets of Jianpi Yiqi prescription (JYP) in the treatment of hepatocellular carcinoma (HCC) based on network pharmacology and explore the effect of JYP on the invasion and proliferation of hepatocellular carcinoma cells via protein tyrosine phosphatase, non-receptor type 1 (PTPN1) by bioinformatics analysis and CRISPR/Cas9. MethodsThe potential targets of JYP in the treatment of HCC were retrieved from the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP), SwissTargetPrediction, GeneCards, NCBI, and CTD. Additionally, the active components of JYP that could interact with PTPN1 were screened out, and then molecular docking between the targets and active components was performed in Autodock 4.0. UALCAN, HPA, and LinkedOmics were used to analyze the expression of PTPN1 in the HCC tissue, and the relationship of PTPN1 expression with the overall survival (OS) of HCC patients was discussed. CRISPR/Cas9 was used to knock down the expression of PTPN1 in HepG2 and SK-hep-1 cells, and the knockdown effect was examined by sequencing, Real-time PCR, and Western blot. HepG2 cells were classified into blank control, low-, medium-, and high-dose JYP (5.25, 10.5, 21 g·kg-1), and PTPN1 knockout groups. Real-time PCR and Western blot were employed to determine the mRNA and protein levels, respectively, of PTPN1 in HepG2 cells of each group. The effects of JYP and PTPN1 knockdown on the proliferation, invasion, and apoptosis of HepG2 cells were detected by Cell Counting Kit-8 (CCK-8), Transwell, and Annexin V-FITC/PI methods, respectively. ResultsJYP had the most active components targeting PTPN1, and 31 of the active components had the binding energy less than -5.0 kcal·mol-1 in molecular docking. The mRNA and protein levels of PTPN1 in the HCC tissue were higher than those in the normal tissue (P<0.01). Compared with that in the normal tissue, the mRNA level of PTPN1 in the HCC tissue was up-regulated at the pathological stages Ⅰ-Ⅲ and grades G1-G3 (P<0.01), and it was not significantly up-regulated at the stage Ⅳ or grade G4. The mRNA level of PTPN1 in the TP53-mutated HCC tissue was higher than that in the TP53-unmutated HCC tissue (P<0.01). The high mRNA level of PTPN1 was associated with the OS reduction (P<0.01). After treatment with the JYP-containing serum or knockdown of PTPN1, HepG2 cells demonstrated decreased proliferation and invasion and increased apoptosis (P<0.01). ConclusionPTPN1 may be one of the core targets of JYP in the treatment of HCC. It is highly expressed in the HCC tissue and cells, which is associated with the poor prognosis of patients. The expression level of PTPN1 is significantly up-regulated in the HCC tissue of the patients with TP53 mutation. However, TP53 mutation or deletion does not affect the expression of PTPN1 in HCC cells. JYP can significantly down-regulate the expression of PTPN1 to inhibit the proliferation and invasion and promote the apoptosis of HCC cells.

AIM: To investigate the effects of insulin-like growth factor 1(IGF-1)on the secretion of transforming growth factor β2(TGF-β2), matrix metalloproteinase 2(MMP-2)and hypoxia-inducible factor 1α(HIF-1α)in human scleral fibroblasts(HSF)and their mechanism.METHODS: The cells were cultured with IGF-1 and PI3K/AKT pathway inhibitor LY294002, respectively. CCK-8 method was used to detect cell viability and determine the optimal concentration and time of drug action. Cell migration activity was observed by cell scratch method. To determine the effects of IGF-1 on HSF cells and the regulatory role of PI3K/AKT pathway, HSF cells were divided into control group(without drugs), IGF-1(80 μg/L)group, IGF-1+LY294002(80 μg/L+5 mmol/L)group, and LY294002(5 mmol/L)group, and were cultured for 24 h; the protein expression levels of TGF-β2, MMP-2, HIF-1α, PI3K and AKT were detected by Western blot; the fluorescence expression of TGF-β2, MMP-2 and HIF-1α was detected by cellular immunofluorescence.RESULTS: The results of CCK-8 showed that the cell viability of the 80 μg/L IGF-1 group cultured with different concentrations of IGF-1 was the highest(all P<0.05), and the cell viability of the 80 μg/L IGF-1 group at 24 h was the highest under different culture times. Therefore, the concentration of IGF-1 was selected as 80 μg/L for 24 h. The viability of cells cultured with different concentrations of LY294002 gradually decreased from 6 h(all P<0.05). According to the IC50 value, therefore, the concentration of LY294002 was selected as 5 mmol/L for 24 h. The cell scratch results showed that compared with the control group, the cell mobility of 40 μg/L and 80 μg/L IGF-1 groups was increased(all P<0.05). Compared with the control group, cell mobility in the 2.5 and 5 mmol/L LY294002 groups was decreased(all P<0.05). Western blot results showed that compared with the control group, the protein expressions of TGF-β2, MMP-2, HIF-1α, PI3K and AKT in the IGF-1 group were increased, while those in the LY294002 group were decreased(all P<0.05). Compared with the IGF-1 group, the expression levels of TGF-β2, MMP-2, HIF-1α, PI3K and AKT in the IGF-1+LY294002 group were decreased(all P<0.05). The results of cell immunofluorescence showed that compared with the control group, the fluorescence expressions of TGF-β2, MMP-2 and HIF-1α in the IGF-1 group were increased, while those in the LY294002 group were decreased(all P<0.05). Compared with the IGF-1 group, the fluorescence expressions of TGF-β2, MMP-2 and HIF-1α in the IGF-1+LY294002 group were significantly decreased(all P<0.05).CONCLUSION: IGF-1 promoted the proliferation and migration of human HSF. IGF-1 may up-regulate the expression of TGF-β2, MMP-2 and HIF-1α in HSF through the PI3K/AKT signaling pathway, and participate in the occurrence and development of myopia.

Objective:To summarise the main points of operation during thyroid surgery using bilateral axillo-breast approach (BABA) with a domestic robot and to analyse the learning curve.Methods:From May. 2023 to Oct. 2023, we retrospectively analysed the clinical data of 38 patients who underwent thyroid surgery with domestically manufactured robot via BABA attending the Department of Thyroid and Breast Surgery of the 960th Hospital of PLA Joint Logistics Support Force, proposed and constructed learning curves using cumulative and analytical methods to study the minimum number of learning cases required for the loading time of assistants and surgeon-in-charge with da Vinci surgical experience to transition from the initial learning stage to the proficiency stage. The age, BMI, surgical time (loading time, operating time), postoperative drainage time, and number of lymph nodes dissected were compared among patients at different stages of the learning curve.Results:A total of 38 thyroidectomy patients successfully underwent surgery, with an average surgical time of (176.61 ± 47.98) minutes. After 18 cases, the assistant's loading time shortened and stabilized at (42.20 ± 3.44) minutes. The operator reached peak proficiency at the 18th case (loading time, operating time), which was considered the dividing point between the learning phase and the proficiency phase. During the learning phase, the average surgical time was (209.72 ± 49.28) minutes, operation time: (165.44 ± 49.93) minutes, while in the proficiency phase, the average surgical time decreased to 146.80 ± 18.34 minutes, operation time: (104.60 ± 19.01) minutes. There were no statistically significant differences in baseline characteristics such as age, BMI, postoperative drainage time, or the number of central compartment lymph nodes dissected between the two phases ( P > 0.05) . Conclusion:Over the results of this study, it was shown that for robosurgeons with experience in da Vinci robotic surgery, the transition from the learning stage to the proficiency stage could be considered after crossing the learning curve for 18 cases, and that assistants could become proficient in loading techniques after 18 procedures.

Objective To investigate the mechanism by which artesunate(ART)attenuates intestinal mucosal barrier damage in acute graft-versus-host disease(aGVHD)and the synergistic effect of ART in combination with dexamethasone(DXM)in the treatment of aGVHD mice.Methods The aGVHD mouse model was established by bone marrow haematopoietic stem cell transplantation.The mice were divided into 9 groups,including normal mice control(Ctrl),aGVHD mice(aGVHD),normal mice receiving ART[30 mg/(kg·d)],aGVHD mice receiving low-dose ART[10 mg/(kg·d)],aGVHD mice receiving medium-dose ART[30 mg/(kg·d)],aGVHD mice receiving high-dose ART[50 mg/(kg·d)],aGVHD mice receiving DXM[20 mg/(kg·d)],aGVHD mice receiving ART[30 mg/(kg·d)]and DXM[20 mg/(kg·d)],and aGVHD mice receiving ART[30 mg/(kg·d)]and halved DXM[10 mg/(kg·d)].Survival rate and clinical parameters were assessed.HE staining and Alcian blue-periodic acid-Schiff(AB-PAS)staining were used to observe the histopathological changes in the intestinal mucosa of the mice;Real-time PCR,Western blotting and immunohistochemistry were used to detect the structure of the intestinal mucosal barrier,the T cell differentiation related transcription factors and cytokines,and the key enzymes of energy metabolism.Flow cytometry was used to detect the T helper cell 17(Th17)and regulatory T cells(Treg).Results After 30 days of ART treatment,aGVHD mice showed significant relief of systemic symptoms and increase in survival rate.In aGVHD mice treated with ART,the intestinal mucosal barrier structure was restored,and the intestinal mucosal permeability was reduced.The activity of AMP-activated protein kinase(AMPK)/mTOR pathway was inhibited,and the energy metabolism pattern of T cells was dominated by fatty acid synthesis.The balance of Th17/Treg was restored due to the decrease of Th 17 and the increase of Treg.The effect of ART+DXM treatment on aGVHD mice was comparable to that of DXM treatment alone,and the survival rate of mice was higher.In particular,the recovery of the intestinal mucosal barrier function was most obvious in the mice treated with ART+half-dose DXM.Conclusion ART reduces the immune injury of allo-T cells to the intestinal mucosal barrier by recovering the Th17/Treg balance,thus maintaining the integrity of the intestinal mucosal barrier function.The synergistic effect of ART and DXM combination treatment in aGVHD mice can reduce the incidence of DXM side effects by decreasing the dosage of DXM.
