Objective To investigate the effects of galangin on the migration and invasion abilities of cervical cancer Hela cells and its potential mechanisms.Methods Hela cells were treated with different concentrations of galangin(0,5,10,20,40,60,80,100 μmol/L)for 48 hours,and CCK-8 assay was used to assess the impact of galangin on cell viability and to determine the half-maximal lethal concentration(IC50)of galangin.Hela cells were divided into a control group(0 μmol/L)and a galangin group(40 μmol/L treatment).Scratch wound healing assays and Transwell chamber assays were conducted to evaluate the migration and invasion abilities of the cells in each group.Western Blot was used to detect the protein expression of E-cadherin and N-cadherin.DIA quantitative proteomics technology was used to detect and screen the differentially expressed proteins between the two groups.Biological function enrichment analysis of the differential genes was performed using the KEGG Pathway and Gene Set Enrichment Analysis(GSEA)methods.Western Blot was used to verify the expression levels of Hippo/YAP signaling pathway-related proteins YAP and p-YAP.Results Compared to the control group,galangin(40 μmol/L)significantly inhibited the viability of Hela cells in a concentration-dependent manner(P<0.001).Compared with the control group,the scratch healing ability and invasion ability of cervical cancer Hela cells treated with galangin(40 μmol/L)were significantly reduced(P<0.001).The expression of E-cadherin protein was increased(P<0.05)and the expression of N-cadherin protein was decreased(P<0.001)in the galangin group(40 μmol/L)compared to the control group.KEGG and GSEA enrichment results indicated that the inhibition of malignant progression in cervical cancer by galangin was significantly associated with the Hippo/YAP signaling pathway.Western Blot confirmed that the expression level of the hallmark protein p-YAP in the Hippo signaling pathway was increased(P<0.01),while the expression level of YAP protein was decreased(P<0.05).Conclusion Galangin inhibits the proliferation,migration and invasion abilities of Hela cells in a dose-dependent manner.The underlying mechanism might be associated with the activation of the Hippo/YAP signaling pathway.

Purpose To investigate the effect of CD147 on the proliferation,invasion and migration of cervical cancer cells and its potential molecular mechanism.Methods The expres-sion data of BSG gene(encoding CD147 protein)in cervical cancer samples were downloaded from UCSC database,and the prognosis of different groups of samples was evaluated by Log-rank test.Western blot was used to detect CD147 expression in the Siha and Hela and H8 cells.The expression of CD147 was downregulated by the lentivirus transfection into Hela cells and its transfection efficiency was verified.Western blot was used to detect the expression of p-Akt,p-mTOR,ACC1,FASN,E-cad-herin and N-cadherin in each group.The content of fatty acids in the cells was detected by BODIPY staining and fatty acid kit.Cell proliferation,invasion and migration were detected by CCK-8,plate cloning and Transwell assay.The cell proliferation,in-vasion and migration ability were detected by plate cloning ex-periment and Transwell test.Results The expression of CD147 in cervical cancer tissues was higher than that in normal cervical tissues(P＜0.01).Patients with overexpression of CD147 had poor prognosis.Western blot results showed that compared with H8 cells,the expression of CD147 protein in Siha and Hela cells was increased(P=0.011).After down-regulation of CD147,the protein expression of CD147,ACC1 and FASN in the sh-CD147 group was decreased compared with those in the Hela group(P＜0.001).BODIPY fluorescence staining was weak-ened and fatty acid content was decreased(P＜0.001).The a-bility of cell colony formation,invasion and migration was de-creased.The expression of E-cadherin protein in sh-CD147 group was increased,and the expression of N-cadherin,p-Akt and p-mTOR was decreased.Compared to sh-CD147,after treatment with Akt agonist SC-79(sh-CD147-SC79),the ex-pression of p-Akt,p-mTOR,ACC1,FASN,N-cadherin in cells was increased,and the expression of E-cadherin was decreased,and the results of lipid staining and fatty acid content were con-sistent with the expression of key enzymes(P＜0.01),and the cell proliferation,invasion and migration ability were significant-ly enhanced.Conclusion CD147 through Akt/mTOR signaling pathways regulating the fatty acid synthesis promotes cervical cancer cell proliferation,invasion and migration.

Objective To explore the molecular mechanism of CAFs promoting energy metabolism of EC9706 cells by collecting conditioned media of cancer-associated fibroblasts(CAFs).Methods Cell viability was detected by MTT,and the CAFs conditioned medium(CAFM)most suitable for indirect co-culture was selected with EC9706 cultured in DMEM high glucose medium as control.The contents of lactic acid and glucose in the supernatant of EC9706 cells were determined by colorimetry.The energy metabolism of EC9706 cells in DMEM and CAFM was detected by seahorse system energy metabolism analysis system.Real time quantitative polymerase chain reaction(RT-qPCR)and western blotting were used to detect the mRNA and protein expression of energy metabolism related molecules.Results Compared with normal esophageal fibroblast conditioned medium(NFM),CAFs conditioned medium of 50%-60%and 70%-80%cell fusion degree promoted the proliferation of EC9706 cells(P<0.01),and CAFM groups with 70%-80%cell fusion degree promoted the proliferation of EC9706 cells compared with the control group.When the CAFM content was 60%,the proliferation of EC9706 cells was significantly increased(P<0.01).Compared with DMEM,CAFM could increase glucose uptake,superlactate content,basal respiratory value,basal glycolysis,compensatory glycolysis(P<0.05),non-mitochondrial oxygen consumption,maximum respiratory value,oxygen consumption for ATP synthesis,and reserve respiratory capacity(P<0.01)of EC9706 cells.RT-qPCR results showed that CAFM could also up-regulate the Hypoxic-inducible factor-1α(HIF-1α),Hexokinase-2(HK2)and Monocarboxylic acid transporter 1(MCT1)of EC9706 cells(P<0.05).Expression of Glucose transporter 1(GLUT1),Pyruvate kinase 2(PKM2)mRNA(P<0.01).Western blot showed that compared with DMEM,the protein expression of HK2,PKM2,MCT1 and GLUT1 was significantly increased(P<0.01).Conclusion CAFM can promote energy metabolism of EC9706 cells by promoting mRNA and protein expressions of HK2,PKM2,HK2,GLUT1,MCT1 and MCT4 under in vitro culture conditions.

Objective:To review relevant research on the application of self-help intervention model in adult depression patients, analyze the main characteristics and application effects of self-help intervention model, in order to provide reference for related research in this field.Methods:According to the methodological framework of the scope review, searched 12 Chinese and English databases including CNKI, Wanfang, PubMed, Web of Science, etc. from the establishment of the database until April 20, 2021, and sorted and analyzed the obtained documents according to the inclusion and exclusion standards.Results:A total of 45 documents were included, of which only 5 were from China; the included studies were mainly based on the Internet platform, using cognitive behavioral therapy, reading therapy, acceptance and commitment therapy, and problem-solving therapy for intervention; the duration of the intervention was 3 weeks to 4 months, participants complete an intervention module or read a specified number of chapters every 3 to 7 days on average, and receive regular guidance and supervision from the intervention facilitator every 1-2 weeks. The total contact time with the facilitator was 80-160 minutes. Various modes of self-help intervention based on the Internet could effectively improve the negative emotions of patients with depression.Conclusions:The self-help intervention model has shown good results in the treatment of patients with depression, but there is a lack of local intervention research in China, and there is no clear standard for the number of interventions and the length of the intervention guide. Under the general trend of "Internet + medical health", it is necessary to actively construct a self-help intervention model for depression with Chinese cultural characteristics, and form a systematic and standardized intervention strategy to address the many obstacles in time, location, resources and cost of people with depression, and finally achieve the purpose of improving the patients′ depressive symptoms and helping them to restore their social functions.

Objective:To explore the outcome of sponge forceps assisted threading with Speedbridge technique for the treatment of acute closed Achilles tendon rupture.Methods:A retrospective case series study was conducted on 20 patients with acute closed Achilles tendon rupture treated in Zhengzhou Orthopedic Hospital from December 2019 to December 2021. There were 18 males and 2 females, with age range of 24-43 years [(29.5±7.6)years]. All patients were with unilateral injury, involving the left side in 13 patients and right side in 7. Examinations revealed a palpable defect in the Achilles tendon and positive Thompson test. A longitudinal incision was made at the medial edge of the ruptured tendon. Three nonabsorbable sutures were passed through the proximal stump with sponge forceps, bypassed the rupture site and fixed directly into the calcaneal bone. The disrupted tendon ends were aligned by the tendon-bundle technique using 4-0 absorbable sutures. The operation time and incision length were documented. The ankle joint range of motion (dorsiflexion/plantar flexion), American Orthopedic Foot and Ankle Society (AOFAS) ankle-hindfoot score and Achilles tendon total rupture score (ATRS) in the affected and healthy side were compared at 3, 6 and 12 months postoperatively. The wound healing and complications were observed.Results:All patients were followed up for 12-16 months [(13.2±2.5)months]. The operation time was 40-66 minutes [(52.0±10.3)minutes], with the incision length of 3-4 cm [(3.3±0.7)cm]. In the affected side at 3 and 6 months postoperatively, the ankle joint dorsiflexion [(5.6±1.5)°, (10.5±0.2)°] and plantar flexion [(28.4±3.2)°, (33.5±1.5)°] showed statistically significant difference compared with the healthy side (all P<0.05). The ankle joint dorsiflexion [(13.9±0.7)°] and plantar flexion [(38.3±4.4)°] in the affected side were not statistically different from that of the healthy side at 12 months postoperatively (all P>0.05). The AOFAS ankle-hindfoot score was (58.3±5.4)points, (84.9±7.1)points and (91.8±6.3)points at 3, 6 and 12 months postoperatively, showing a gradual rise (all P<0.05). The ATRS was (60.5±4.9)points, (85.5±9.0)points and (93.1±5.7)points at 3, 6 and 12 months postoperatively, showing a gradual rise (all P<0.05). All incisions were healed primarily. No patients had wound infection, nerve injury or re-rupture. Pain at the anchor insertion site occurred in 2 patients at 1 month after operation and relieved after active functional rehabilitation at 4 months after operation. Transient pain at the Achilles tendon insertion occurred in 1 patient at 6 months after operation, and relieved after 2 weeks of oral non-steroidal anti-inflammatory drugs treatment. Conclusion:For acute closed Achilles tendon rupture, sponge forceps assisted threading with Speedbridge technique can attain short operation time, small incision and good functional recovery, with few complications.

Objective To investigate the establishment of a six-gene-edited pig-to-non-human primate kidney xenotransplantation model. Methods The kidney of humanized genetically-edited pig (GTKO/β4GalNT2KO/CMAHKO/hCD55/hCD46/hTBM) was transplanted into a cynomolgus monkey. The survival of the recipient and kidney condition after blood perfusion were observed. The parenchymal echo, blood flow changes, and size of the kidney were monitored on a regular basis. Routine blood test, kidney function test and electrolyte assessment were carried out. Dynamic changes of urine, feces and body mass were monitored. At the end of life, the transplant kidney, heart, liver, spleen, lung, and cecum were collected for pathological examination. Results The recipient died at postoperative 7 d. After blood flow was restored, the kidney was properly perfused, the organ was soft and the color was normal. At the end of the recipient's life, a slight amount of purulent secretion was attached to the ventral side of the kidney, with evident congestion and swelling, showing the appearance of "red kidney". Postoperatively, the echo of renal parenchyma was increased, blood flow was decreased, the cortex was gradually thickened, and a slight amount of effusion surrounded the kidney and abdominal cavity over time. In the recipient, the amount of peripheral red blood cells, hemoglobin, albumin, and platelets was progressively decreased, and serum creatinine level was increased to 308 μmol/L at postoperative 7 d, whereas the K⁺ concentration did not significantly change. Light yellow urine was discharged immediately after surgery, diet and drinking water were resumed within postoperative 3 h, and light yellow and normal-shape stool was discharged. The reddish urine was gradually restored to normal color within postoperative 1 d, which were consistent with the results of the routine urine test. A large amount of brown bloody stool was discharged twice in the morning of 2 d after surgery. Omeprazole was given for acid suppression, and the stool returned to normal at postoperative 4 d. The β₂-microglobulin level was increased to 0.75 mg/L at postoperative 7 d. The body mass was increased by 1.7 kg. Autopsy pathological examination showed interstitial edema and bleeding of the transplant kidney, a large amount of infiltration of lymphocytes and macrophages, infiltration of lymphocytes in the arteriole wall and arterial cavity, accompanied by arteritis changes, lymphocyte infiltration in the cecal stroma and congestion in the spleen tissues. No significant abnormal changes were observed in other organs. Conclusions The humanized genetically-edited pig-to-non-human primate kidney xenotransplantation model is successfully established, and postoperative survival of the recipient is 1 week.

Objective:To observe the effect of sodium fluoride (NaF) on the expression of phosphatidylinositol-3-kinase/protein kinase B (PI3K/Akt) signal and apoptosis in human osteosarcoma Saos-2 cells.Methods:Saos-2 cells were divided into 0 (control), 5, 10, 20 and 40 mg/L fluoride groups ( n= 3) according to the dose of NaF. The cells were collected after 24 and 48 h of culture in vitro. Western blotting was used to detect the expressions of PI3K/Akt signal and Forkhead transcription factor (FoxO) 1, and the apoptosis level of Saos-2 cells was detected by flow cytometry. Results:There were no significants differences in the expressions of PI3K and Akt in Saos-2 cells at 24 and 48 h ( P > 0.05).

Conclusion:Fluoride can directly activate the PI3K/Akt signaling pathway in osteoblasts, and then has anti-apoptotic effect.

Objective:To screen the time points of high survival rate and efferocytosis dysfunction of rat alveolar macrophages stimulated by cigarette smoke extract (CSE), establish an in vitro model of alveolar macrophage efferocytosis function, and study chronic respiratory diseases with chronic inflammatory reaction as the main pathological changes. Methods:① Time point screening experiment: rat alveolar macrophages (NR8383 cells) were cultured in vitro, and the cells in logarithmic growth phase were divided into blank control group (100 μL complete medium) and 5% CSE group (90 μL complete medium + 10 μL 100% CSE). Alma blue method was used to detect the effect of 5% CSE on the activity of NR8383 cells at 6, 12, 24 and 48 hours. ② Apoptosis induction experiment: rat type Ⅱ alveolar epithelial cells (RLE-6TN cells) were cultured in vitro as phagocytic target cells of NR8383 cells, and the cells in logarithmic growth phase were divided into blank control group and 10, 30 and 60 minutes groups after ultraviolet exposure (apoptosis was induced by 30 000 μJ/cm 2 ultraviolet irradiation for 15 minutes). Flow cytometry was used to detect the apoptosis rate of RLE-6TN cells cultured for 10, 30 and 60 minutes after ultraviolet exposure. ③ Cell efferocytosis experiment: NR8383 cells in logarithmic phase were divided into blank control group and 5% CSE group. Two hours before NR8383 cells were stimulated by CSE for 6, 12 and 24 hours, RLE-6TN cells were exposed to ultraviolet to induce apoptosis, and the RLE-6TN cell suspension was added to NR8383 cells (the ratio of RLE-6TN cells to NR8383 cells was 5∶1). Flow cytometry was used to detect the efferocytosis rate of NR8383 cells to RLE-6TN cells at different time points treated with 5% CSE. Results:① Compared with the blank control group, the activity of NR8383 cells significantly decreased after treatment with 5% CSE for 48 hours [cell reduction rate: (68.5±4.1)% vs. (73.6±2.3)%, P < 0.05]. However, there were no significant differences when the activities of NR8383 cells treated with 5% CSE for 6, 12 and 24 hours were compared with the blank control group, so these three time points were selected for the subsequent establishment of alveolar macrophage cell efferocytosis dysfunction in vitro model experiment. ② Compared with the blank control group, the apoptosis rate of RLE-6TN cells significantly increased at 10, 30 and 60 minutes after ultraviolet exposure [(66.87±8.63)%, (85.51±2.39)%, (96.13±2.74)% vs. (9.13±3.17)%, all P < 0.01] in a time-dependent manner. Considering that it taked about 50 minutes for RLE-6TN cells to be labeled with PKH26 membrane labeling probe, 10 minutes after ultraviolet exposure was selected to label RLE-6TN cells. ③ Compared with the blank control group, the efferocytosis function of NR8383 cells was significantly decreased after treatment with 5% CSE for 12 hours [cell efferocytosis rate: (33.64±1.30)% vs. (44.02±2.71)%, P < 0.01], but there was no significant effect on the efferocytosis function of NR8383 cells at 6 hours and 24 hours. Conclusions:CSE can induce alveolar macrophage cell efferocytosis dysfunction. Based on the test results of the effect of 5% CSE on NR8383 cell activity and cell efferocytosis function, 12 hours with high survival rate and weak efferocytosis effect of NR8383 cells can be selected as the in vitro model condition of alveolar macrophage cell efferocytosis dysfunction.

Objective:To examine the correlation between neutrophil-lymphocyte ratio (NLR), lymphocyte-monocyte ratio (LMR) and neutrophil-monocyte ratio (NMR) for postoperative pneumonia or long-term overall survival in patients with esophageal cancer after neoadjuvant therapy.Methods:The clinical data of 137 patients, including 111 males and 26 females, with the age of ( M( Q R))61(10) years (range: 45 to 75 years), undergoing radical resection of esophageal cancer after neoadjuvant therapy admitted at Department of Thoracic Surgery, West China Hospital from January 2016 to May 2019 were analyzed retrospectively. The blood routine one or two days before surgery and the occurrence of pneumonia after surgery were collected via hospital information system. The absolute count of neutrophils, lymphocytes and monocytes was recorded, to calculate NLR, LMR and NMR. The survival of patients was recorded systematically via follow-up. In the first part, the influencing factors of postoperative inflammation were analyzed, to group the patients into two groups according to the occurrence of postoperative pneumonia. χ 2 test, t-test or rank-sum test were conducted for inter-group comparison. In the second part, cut-off values of inflammatory biomarkers were obtained with the receiver operating characteristic (ROC) curve and grouped, with postoperative pneumonia as endpoint criteria. Independent factors correlated with postoperative pneumonia were determined through univariate and multivariate Logistic regression analysis. In the third part, the analysis on prognosis factors was carried on, with the survival as endpoint criteria. Cut-off values of inflammatory biomarkers were obtained with X-Tile software and grouped. The survival analysis was carried on with univariate and multivariate Cox proportional hazards regression model, and the Kaplan-Meier curve was drawn finally. The results of survival analysis were verified by Log-rank test. Results:Median follow-up time was 614 (299) days (range: 382 to 1 612 days). Cut-off values of NLR, LMR, and NMR obtained via the ROC curve were 3.0, 3.9, and 6.2, respectively. According to the multivariate Logistic regression analysis, NLR>3.0 ( OR=2.740, 95% CI: 1.221 to 6.152, P=0.015) and LMR>3.9 ( OR=0.140, 95% CI: 0.022 to 0.890, P=0.037) were independent prognosis factors for postoperative pneumonia in patients with esophageal cancer after neoadjuvant therapy. Cut-off values of NLR, LMR, and NMR obtained with X-Tile software were 3.3, 4.2, and 7.2, respectively. Through multivariate Cox proportional risk regression analysis, late tumor ypTNM staging (8th AJCC) ( HR=2.087, 95% CI:1.079 to 4.038, P=0.029), poor pathologic response ( HR=2.251, 95% CI: 1.117 to 4.538, P=0.023), and LMR>4.2 ( HR=0.347, 95% CI: 0.127 to 0.946, P=0.039) could be independent prognosis factors for overall survival. Kaplan-Meier survival analysis indicated that the overall survival of patients with LMR ≤4.2 was worse ( P=0.002), with the 1-year overall survival rate of 82.9%, and the 1-year overall survival rate of patients with LMR>4.2 was 94.6%. Conclusion:Preoperative LMR ≤3.9 and NLR>3.0 can be considered as independent prognosis factors for postoperative pneumonia, while LMR≤4.2 as one of independent prognosis factors for overall survival.
