Objective:To analyze the electrocardiographic characteristics of patients with chronic pulmonary artery stenosis (PAS), and to explore their relationship with disease severity indicators.Methods:The study was a retrospective case-series analysis. Patients with chronic PAS admitted to Gansu Provincial Hospital from January 2018 to July 2021 were enrolled. The clinical data and the results of electrocardiography, transthoracic echocardiography, right cardiac catheterization, N-terminal B-type natriuretic peptide (NT-proBNP) measurement and 6-min walking distance test of patients were analyzed. The linear regression model or logistic regression model was used to analyze the relationship between electrocardiographic characteristics and the disease severity in patients with chronic PAS.Results:Sixty-three patients aged (62.1±9.7) years including 43 females (68.3%) were enrolled in the study. Among them, 62 patients (98.4%) had (R 1+S Ⅲ)-(S Ⅰ+R Ⅲ)<1.5 mV, and no patients had V 5lead R: S ratio to V 1 lead R: S<0.04 and V 6 lead R: S ratio<0.4. There were 55 patients (87.3%), with flat or inverted T-waves in V 1, and 10 patients (15.9%) with flat or inverted T-waves in all precordial leads (V 1-V 6). There were 18 patients (28.6%) with flat or inverted T-waves in inferior leads (Ⅱ, Ⅲ, aVF). Multiple liner regression analysis showed that Max R V1, 2+Max S I, aVL-S V1 combined with the number of flat or inverted T-waves in limb leads was independently correlated with atrial area ( R2=0.290, P=0.002); R V1+S V5 was independently correlated with right ventricular area ( R2=0.257, P=0.001); R peak V 1 combined with the number of flat or inverted T waves in precordial leads was independently correlated with tricuspid annular plane systolic excursion ( R2=0.407, P<0.001); (R 1+S Ⅲ)-(S Ⅰ+R Ⅲ) combined with the number of flat or inverted T waves in precordial leads was independently correlated with NT-proBNP ( R2=0.504, P<0.001); Max R V1, 2+Max S I, aVL-S V1 were independently correlated with right atrial pressure ( R2=0.803, P=0.036); (R 1+S Ⅲ)-(S Ⅰ+R Ⅲ) were independently correlated with mean pulmonary artery pressure ( R2=0.302, P<0.001); R aVRcombined with the number of flat or inverted T-waves in precordial leads was independently correlated with cardiac index ( R2=0.173, P=0.003); (R 1+S Ⅲ)-(S Ⅰ+R Ⅲ) was independently correlated with pulmonary vascular resistance ( R2=0.173, P=0.002); R peak V 1 combined with the number of flat or inverted T-waves in precordial leads was independently correlated with mixed vein oxygen saturation ( R2=0.302, P<0.001). Conclusion:The vast majority of patients with chronic PAS have (R 1+S Ⅲ)-(S Ⅰ+R Ⅲ)<1.5 mV and flat or inverted T-wave in V 1 lead, and some characteristic electrocardiographic manifestations are correlated with indicators of disease severity.

Objective To investigate the expression levels and clinical significance of differentially expressed microRNAs(miRNAs)based on high-throughput sequencing in patients with left ventricular hypertrophy(LVH)and their possible regulatory mechanisms.Methods The miRNA sequencing was performed on plasma samples from 4 LVH patients and 4 healthy volunteers,and qRT-PCR validation was performed on plasma samples from 25 healthy volunteers and 35 LVH patients.The target genes of the obtained differentially expressed miRNA were predicted.The molecular function(MF),biological process(BP)and cellular components(CC)of these miRNAs were predicted by the Gene Ontology(GO)enrichment analysis,and their signal pathways were predicted by the Kyoto Encyclopedia of Genes and Genomes analysis.Meanwhile,the protein-protein interaction network was constructed.The diagnostic values of 2 differentially expressed miRNAs(hsa-miR-942-5p and hsa-miR-184)in LVH were analyzed by the area under the receiver operating characteristic(ROC)curve(AUCROC).Results A total of 945 differentially expressed miRNAs were identified,of which 1 and 9 were observed to be significantly upregulated and downregulated,respectively.The expression levels of hsa-miR-942-5p and hsa-miR-184 were verified by qRT-PCR to be significantly downregulated.The AUCROC of hsa-miR-942-5p and hsa-miR-184 were 0.694 6 and 0.880 4,respectively.Bioinformatics analysis revealed that the target genes were mainly enriched in the cell senescence,sphingolipid metabolism,and TGF-β,p53,and diabetic metabolism related signaling pathways.Conclusion The expression levels of hsa-miR-942-5p and hsa-miR-184 in plasma of LVH patients are significantly decreased,suggesting that they have good diagnostic potential.

c-Myc protein encoded by c-Myc (cellular-myelocytomatosis viral oncogene) gene regulates the related gene expression through the Wnt/β-catenin signaling pathway, and has received extensive attention in recent years. The purpose of this study was to express Helicoverpa armigera c-Myc gene (Ha-c-Myc) by using prokaryotic expression system, prepare the polyclonal antibody, examine the spatio-temporal expression profile of Ha-c-Myc, and investigate the possible function of Ha-c-Myc in regulating H. armigera sterol carrier protein-2 (SCP-2) gene expression. The Ha-c-Myc gene was amplified by PCR and cloned into a prokaryotic expression plasmid pET-32a(+). The recombinant plasmid pET-32a-Ha-c-Myc was transformed into Escherichia coli BL21. IPTG was used to induce the expression of the recombinant protein. Protein was purified by Ni²⁺-NTA column and used to immunize New Zealand rabbits for preparing the polyclonal antibody. The Ha-c-Myc expression levels in different developmental stages (egg, larva, prepupa, pupa, and adult) of H. armigera and different tissues (midgut, fat body, head, and epidermis) of the prepupa were determined by real-time quantitative reverse transcription PCR (qRT-PCR). Ha-c-Myc siRNA was synthesized and transfected into H. armigera Ha cells. The relative mRNA levels of Ha-c-Myc and HaSCP-2 in Ha cells were detected by qRT-PCR. Results showed that the pET-32a-Ha-c-Myc recombinant plasmid was constructed. The soluble Ha-c-Myc protein of about 65 kDa was expressed in E. coli. The polyclonal antibody was prepared. Western blotting analysis suggested that the antibody had high specificity. Enzyme linked immunosorbent assay (ELISA) showed that the titer of the antibody was high. Ha-c-Myc gene expressed at all developmental stages, with high levels in the early and late instars of larva, and the prepupal stage. Tissue expression profiles revealed that Ha-c-Myc expressed in various tissues of prepupa, with high expression level in the midgut, but low levels in the epidermis and fat body. RNAi results showed that the knockdown of Ha-c-Myc expression significantly affected transcription of HaSCP-2, leading to a 50% reduction in HaSCP-2 mRNA expression level. In conclusion, the Ha-c-Myc was expressed through a prokaryotic expression system, and the polyclonal anti-Ha-c-Myc antibody was obtained. Ha-c-Myc may promote the expression of HaSCP-2 and play an important role in the lipid metabolism of H. armigera. These results may facilitate further study on the potential role and function mechanism of Ha-c-Myc in H. armigera and provide experimental data for exploring new targets of green pesticides.

Objective:To investigate the regulatory effect of long non-coding RNA (lncRNA) FTX on gastric cancer cell proliferation through miR-22-3p/NOD-like receptor protein 3 (NLRP3) inflammasome pathway.Methods:The gastric cancer cell line NCI-N87 were divided into blank control group, si-FTX-NC group, si-FTX group, si-FTX+miR-22-3p inhibitor-NC group and si-FTX+miR-22-3p inhibitor group. Quantitative real-time fluorescent PCR was performed to analyze the expression levels of lncRNA FTX and miR-22-3p, clone formation assay was performed to analyze the proliferation ability of NCI-N87 cells, western blotting was performed to analyze the expressions of NLRP3 inflammasome pathway proteins, and dual-luciferase reporter assay was performed to analyze the targeting relationship between lncRNA FTX and miR-22-3p.Results:The relative expressions of lncRNA FTX in the blank control group, si-FTX-NC group, si-FTX group, si-FTX+miR-22-3p inhibitor-NC group and si-FTX+miR-22-3p inhibitor group were 1.03±0.09, 1.01±0.15, 0.42±0.08, 0.45±0.06 and 0.46±0.13 respectively, with a statistically significant difference ( F=52.19, P<0.001). The relative expressions of miR-22-3p were 1.04±0.12, 0.97±0.08, 2.26±0.15, 2.23±0.13 and 1.15±0.11 respectively, with a statistically significant difference ( F=178.53, P<0.001). Compared with the blank control group and si-FTX-NC group, the relative expressions of lncRNA FTX in the si-FTX group, si-FTX+miR-22-3p inhibitor-NC group and si-FTX+miR-22-3p inhibitor group decreased (all P<0.001). Compared with the blank control group, si-FTX-NC group and si-FTX+miR-22-3p inhibitor group, the relative expressions of miR-22-3p in the si-FTX group and si-FTX+miR-22-3p inhibitor-NC group increased (all P<0.001). The clones of the five groups were 115.50±7.25, 112.33±8.46, 54.83±5.17, 56.17±6.32 and 85.67±9.43, with a statistically significant difference ( F=91.67, P<0.001). The levels of NLRP3 protein in the five groups were 1.84±0.17, 1.86±0.12, 0.95±0.09, 0.97±0.11 and 1.28±0.19, with a statistically significant difference ( F=60.62, P<0.001). Compared with the blank control group and si-FTX-NC group, the number of clones and the level of NLRP3 protein of the si-FTX group, si-FTX+miR-22-3p inhibitor-NC group and si-FTX+miR-22-3p inhibitor group decreased (all P<0.05). Compared with the si-FTX+miR-22-3p inhibitor group, the number of clones and the level of NLRP3 protein in the si-FTX group and si-FTX+miR-22-3p inhibitor-NC group decreased (all P<0.05). The dual-luciferase reporter assay found that miR-22-3p was the target gene of lncRNA FTX. Conclusion:Silencing the expression of lncRNA FTX can inhibit the proliferation of gastric cancer cells, and the mechanism may be related to the regulation of lncRNA FTX on the miR-22-3p/NLRP3 inflammasome pathway.

Objective:To investigate the application value of dynamic scintigraphy single-photonemission computed tomography (SPECT) 99m-technetium-galactosyl human serum albumin diethy-lenetriamine pentaacetic ( 99Tc m-GSA) scintigraphy in assessing liver function of perihilar cholangio-carcinoma after portal vein embolization (PVE). Methods:The retrospective and descriptive study was conducted. The clinicopathological data of 16 patients with perihilar cholangiocarcinoma who underwent 99Tc m-GSA scintigraphy after PVE in Beijing Tsinghua Changgung Hospital Affiliated to Tsinghua University from October 2019 to January 2021 were collected. There were 8 males and 8 females, aged from 46 to 78 years, with a median age of 64 years. Observation indicators: (1) liver volume after PVE; (2) liver function after PVE; (3) typical case analysis. Measurement data with normal distribution were represented as Mean± SD. Count data were represented as absolute numbers or percentages. Comparison of data of the same patient was analyzed using the paired t test. Results:(1) Liver volume after PVE:the morphological liver volume and functional liver volume for the 16 patients were (1 420±211)mL and (389±112)mL. The morphological liver volume and functional liver volume were (636±143)mL and (234±106)mL of planning reserved lobe, (784±210)mL and (151±106)mL of planning resection lobe, respectively. The functional liver density (FLD) of planning reserved lobe and planning resection lobe were 0.36±0.12 and 0.19±0.11, showing a significant difference between them ( t=3.794, P<0.05). The planning resection rate of morpholo-gical liver volume and functional liver volume were 37.8%±0.6% and 54.8%±0.2%, showing a significant difference between them ( t=?3.720, P<0.05). (2) Liver function after PVE: 13 of 16 patients completed the indocyanine green (ICG) test, and 3 patients didn't complete the ICG test due to intolerance. For the 13 patients undergoing ICG test, the total ICG-K value was (0.15±0.03)/minutes, and the ICG-K value of planning reserved lobe was (0.07±0.02)/minutes. The total GSA-K value of 16 patients was (0.14±0.10)/minutes, and the GSA-K value of planning reserved lobe was (0.08±0.06)/minutes. (3) Typical case analysis: a 46-year-old male patient with type Bismuth Ⅲa perihilar cholangiocarcinoma was planned to perform perihilar hepatectomy combined with right hepatectomy. The imaging evaluation showed that the volume of reserved liver lobe accounted for 27% of the total liver volume. The serum total bilirubin was 256 μmol/L when admitted and decreased to 118 μmol/L on the day 5 after percutaneous transhepatic biliary drainage. The right anterior and right posterior branches of PVE was performed. SPECT 99Tc m-GSA examination was performed on the day 37 after PVE. The morphological liver volume was 559 mL of planned reserved lobe and 1 461 mL of the whole liver. The planned morphological liver volume resection rate was 61.7%. ICG-K was 0.12/minutes of the whole liver, and 0.04/minutes of planned reserved lobe. The functional liver volume was 134 mL of planned reserved lobe and 309 mL of the whole liver. The planned resection rate of functional liver volume was 56.6%. The GSA-K was 0.20/minutes of the whole liver and 0.09/minutes of planned reserved lobe. R 0 resection was achieved in perihilar hepatectomy combined with right hepatectomy and no liver failure occurred. The survival time of patients was 11 months. Conclusion:Dynamic SPECT 99Tc m-GSA scintigraphy can effectively evaluate the regional function of the reserved liver lobe in patients with perihilar cholangiocarcinoma after PVE.

Objective: To investigate the design of free perforator flap, and the efficacy of utilizing perforator flaps for Ⅳ degree Ischia-sacral ulcer treatment. Methods: From January 2010 to October 2016, 18 patients with Ⅳ degree ischia-sacral ulcer were treated. The surface area of the sacral tail ranged from 4 cm×5 cm to 8 cm ×12 cm.Doppler sonography was used to detect potential perforator.All defects were repaired with free perforator flaps, designed based on the size and shape of the wound. The flap size ranged from 6 cm×11 cm to 9 cm×15 cm. Results: One perforator flap went dehiscence after surgery, repaired by V-Y flap. All the rest of perforator flaps survived well, after 3-24 months follow-up. Flap texture and appearance was good, no ulcer reoccurred. Conclusions The free perforator flap is a simple technique.It does not need to tracethe trunk of vessels, and it does not cause major morbidities to the buttocks. Therefore, it is one of the ideal ways to repair Ⅳ degree Ischia-sacral ulcer.

Objective: To explore the effects of combined transplantation of the rat Schwann cells and fibroblasts (Fbs) on the nerve regeneration of denervated perforator flaps in rats and the mechanism. Methods: (1) Fbs were isolated from the trunk of 2 Sprague-Dawley (SD) rats embryos of 14-16 days′ pregnancy and cultured, and the morphology of the cells was observed. The third passage of cells were used for subsequent experiments. The protein expressions of fibronectin and Ephrin-B2 were observed by immunohistochemical method. The mRNA expression of Ephrin-B2 was detected by real-time fluorescent quantitative reverse transcription polymerase chain reaction (n=3). (2) Schwann cells were isolated from the bilateral sciatic nerves and brachial plexus nerves of 45 SD rats born for 1-3 days and cultured, and the morphology of the cells was observed. The third passage of cells were used for subsequent experiments. The rate of S100 positive cells was detected by immunofluorescence method and flow cytometer, with sample numbers of 9 and 3 respectively. (3) In Dulbecco′s modified Eagle medium (DMEM) high glucose medium, 1 mL Fbs and 1 mL Schwann cells both in the concentration of 1×10⁵ cells/mL were co-cultured as Schwann cells+ Fbs co-culture group, and 2 mL Schwann cells in the concentration of 1×10⁵ cells/mL were cultured alone as Schwann cells alone culture group, with 5 wells in each group. The clusters of Schwann cells in the two groups were observed and counted under inverted phase contrast microscope at post culture hour (PCH) 6 and 24 respectively. The clusters of Schwann cells in Schwann cells+ Fbs co-culture group were observed by immunofluorescence method at PCH 24 too. The protein expressions of EphB2, Sox2, and N-cadherin in Schwann cells of two groups at PCH 24 were detected by Western blotting (n=20). (4) Totally 100 8-week-old male SD rats were selected, and an in situ replanted peritoneal denervated perforator flap was made in each rat. According to the random number table, the rats were divided into simple flap group, Fbs alone transplantation group, Schwann cells alone transplantation group, Schwann cells+ Fbs co-transplantation group, with 25 rats in each group. Flaps of rats in Fbs alone transplantation group and Schwann cells alone transplantation group were injected with 0.4 mL Fb and 0.4 mL Schwann cells respectively (2×10⁶ cells each). Flaps of rats in Schwann cells+ Fbs co-transplantation group were injected with 0.4 mL Fbs and Schwann cells mixed cells (totally 2×10⁶ cells, cell number ratio: 1∶1), and flaps of rats of simple flap group were injected with the same volume of DMEM high glucose medium. On post injection day (PID) 2, 5, 7, 9, and 14, 5 rats in each group were selected respectively according to the random number table. The flap tissue was collected, and the number, diameter, and arrangement of regenerated nerves were observed by immunofluorescence method. Data were processed with completely random designed t test, analysis of variance for repeated measurement, t test, and Bonferroni correction. Results: (1) The third passage of cells isolated and cultured from the rat embryo trunks were uniform in size and shape, long spindle-shaped, with a large proportion of nuclei. Strong positive expressions of fibronectin and Ephrin-B2 protein in cells were observed, and the mRNA expression of Ephrin-B2 was 0.004 1±0.000 8. The cells were identified as Fbs. (2) After 5 days of culture, the primary cells isolated from the sciatic nerves and brachial plexus nerves of neonatal rats were elongated in cell bodies and grew in nest, fence, or vortex-like shape. The third passage of cells were detected by immunofluorescence method and flow cytometer, and the corresponding S100 positive cell rates were (95.9±1.0)% and (95.8±1.1)% respectively. The cells were identified as Schwann cells. (3) At PCH 6 and 24, the cluster numbers of Schwann cells in Schwann cells+ Fbs co-culture group were significantly higher than those of Schwann cells alone culture group (t=6.500, 10.614, P<0.01). At PCH 24, the Schwann cells in Schwann cells+ Fbs co-culture group aggregated into clusters, Fbs dispersed around the Schwann cell clusters, and the protein expressions of EphB2, N-cadherin, and Sox2 in Schwann cells were significantly higher than those in Schwann cells alone culture group (t=2.975, 19.717, 11.159, P<0.05 or P<0.01). (4) On PID 2, a small number of scattered, disordered, short, and thin nerve fibers were observed in the flap tissue of rats in the four groups. From PID 5 to 14, the number of nerve fibers in the flap tissue of rats of Schwann cells+ Fbs co-transplantation group increased gradually, and the nerve fibers were with long diameter and arranged orderly. The number of nerve fibers in the flap tissue of rats of Schwann cells alone transplantation group increased, but the nerve fibers were with short diameter and arranged disorderly, and the number was smaller than that of Schwann cells+ Fbs co-transplantation group. In simple flap group and Fbs alone transplantation group, the nerve fibers in the flap tissue of rats gradually degenerated with gradually decreased number or even disappeared. Conclusions The combined transplantation of Fbs and Schwann cells in rats can regulate Schwann cells migration and clustering by activating Ephrin/Eph-Sox2-N-cadherin signaling pathway, thus promoting the orderly nerve regeneration of denervated perforator flaps in rats.

Objective: To investigate the effects of free mini-flap on tibial side of third toe on repairing skin and soft tissue defect of finger pulp at the end of finger. Methods: From August 2013 to May 2017, 18 patients with skin and soft tissue defect of finger pulp at the end of finger were admitted to our unit, with 12 men and 6 women aged 16 to 54 years. As the skin and soft tissue defect sites, there were 3 cases of thumb, 8 cases of index finger, 4 cases of middle finger, and 3 cases of ring finger. The area of defects ranged from 2.0 cm×1.4 cm to 3.5 cm×2.4 cm. Free mini-flaps on tibial side of third toes were designed according to area and shape of defects, and the length and width of flaps were 0.1 to 0.2 cm longer than the length and width of the defects, respectively. The area of flaps ranged from 2.1 cm×1.5 cm to 3.7 cm×2.6 cm. The end-to-end anastomosis of subcutaneous veins of flaps and superficial veins of the finger-palm side or superficial dorsal digital vein, the end-to-end tension-free anastomosis of the base metatarsal arteries on tibial side of third toe and proper digital arteries of recipient finger were performed. Besides, anastomosis of base metatarsal nerve on tibial side of third toe and proper digital nerve of recipient finger was performed. The donor sites on feet were sutured directly or repaired with full-thickness skin grafts on medial upper leg of the same side. The survival of flaps after operation and the follow-up of patients were observed. Results: All flaps survived well, with good blood supply. Among the 18 patients, 2 patients lost to follow-up, and 16 patients were followed up for 4 to 36 months. The shape and texture of flaps were good. After reconstruction, finger pulps at the end of finger were plump, with fingerprint. Function of the finger restored well, and the two-point discriminatory distances of flaps were 5 to 10 mm. The donor sites on feet of 14 patients healed after the operation, the other 2 patients had necrosis on edge and central area of skin grafts, and the necrotic area healed after dressing change. The skin graft areas on feet were wear-resistant, with slight damage to donor sites and did not influence shoes wearing and walking. Besides, patients did not feel uncomfortable. Conclusions Skin and soft tissue defects of finger pulp at the end of finger repaired by free mini-flaps on tibial side of third toe are with good shape and slight damage to donor sites, and the operation is simple. It is worthy of popularization and application in clinic.

PURPOSE: Hepatocellular carcinoma (HCC) is an aggressive disease with high recurrence rate. However, current staging systems were lack of predictive capacity for HCC recurrence. We aimed to develop prognostic nomograms based on inflammation-related markers for HCC patients underwent hepatectomy. MATERIALS AND METHODS: We recruited 889 surgically treated patients from two medical centers. Independent prognostic factors were identified by cox regression analyses. Nomograms for recurrence-free survival (RFS) and overall survival (OS) were established, and validated internally and externally. The performance, discrimination, and calibration of nomograms were assessed, and compared with existed staging systems. RESULTS: Neutrophil to lymphocyte ratio (NLR) and gamma-glutamyl transpeptidase to platelet ratio (GPR) were the two inflammation-related factor that independently correlated with survival. NLR, GPR, international normalized ratio (INR), microvascular invasion, satellite lesions, tumour number, tumour diameter, and macrovascular invasion were used to construct nomogram for RFS while GPR, total bilirubin, INR, α-fetoprotein, microvascular invasion, satellite lesions, tumour diameter, and macrovascular invasion were for OS. In the training cohort, the C-index of nomogram was 0.701 (95% confidence interval [CI], 0.669 to 0.732) for RFS and 0.761 (95% CI, 0.728 to 0.795) for OS. These results received both internal and external validation with C-index of 0.701 (95% CI, 0.647 to 0.755) and 0.707 (95% CI, 0.657 to 0.756) for RFS, and 0.706 (95% CI, 0.640 to 0.772) and 0.708 (95% CI, 0.646 to 0.771) for OS, respectively. The nomograms showed superior accuracy to conventional staging systems (p<0.001). CONCLUSION: The nomograms based on inflammation-related markers are of high efficacy in predicting survival of HCC patients after hepatectomy, which will be valuable in guiding postoperative interventions and follow-ups.
