OBJECTIVE: To detect and analyze the expression and clinical significance of long non-coding RNA tyrosine kinase non-catalytic region adaptor protein 1-antisense RNA1 (NCK1-AS1) in patients with acute myeloid leukemia (AML). METHODS: 89 AML patients and 23 healthy controls were included from the People's Hospital Affiliated to Jiangsu University. Real-time quantitative polymerase chain reaction (RT-qPCR) was used to detect the expression levels of NCK1-AS1 and NCK1 in bone marrow samples. The relationship between the expression of NCK1-AS1 and the clinical characteristics of patients were analyzed, as well as the correlation between NCK1-AS1 and NCK1. RESULTS: The expression level of NCK1-AS1 in all AML, non-M3 AML and cytogenetically normal AML (CN-AML) patients was significantly higher than that in the control group (P < 0.01, P < 0.05, P < 0.01, respectively). In non-M3 AML, patients with high NCK1-AS1 expression had a significantly lower hemoglobin level than those with low NCK1-AS1 expression (P =0.036), furthermore, NCK1-AS1 ^high patients had shorter overall survival than NCK1-AS1^low patients (P =0.0378). Multivariate analysis showed that NCK1-AS1 expression was an independent adverse factor in patients with non-M3 AML ( HR =2.392, 95% CI :1.089-5.255, P =0.030). In addition, NCK1 expression was also significantly upregulated in all AML, non-M3 AML and CN-AML patients compared with controls (P < 0.01, P < 0.01, P < 0.001, respectively). There was a certain correlation between NCK1-AS1 and NCK1 expression (r =0.37, P =0.0058). CONCLUSION High expression of NCK1-AS1 in AML indicates poor prognosis of AML patients.

Objective: To explore the relationship between low density lipoprotein cholesterol (LDL-C)/high density lipoprotein cholesterol (HDL-C) ratio with the severity of coronary artery disease and 2-yeat outcome in patients with premature coronary heart disease. Methods: This prospective, multicenter, observational cohort study is originated from the PROMISE study. Eighteen thousand seven hundred and one patients with coronary heart disease (CHD) were screened from January 2015 to May 2019. Three thousand eight hundred and sixty-one patients with premature CHD were enrolled in the current study. According to the median LDL-C/HDL-C ratio (2.4), the patients were divided into two groups: low LDL-C/HDL-C group (LDL-C/HDL-C≤2.4, n=1 867) and high LDL-C/HDL-C group (LDL-C/HDL-C>2.4, n=1 994). Baseline data and 2-year major adverse cardiovascular and cerebrovascular events (MACCE) were collected and analyzed in order to find the differences between premature CHD patients at different LDL-C/HDL-C levels, and explore the correlation between LDL-C/HDL-C ratio with the severity of coronary artery disease and MACCE. Results: The average age of the low LDL-C/HDL-C ratio group was (48.5±6.5) years, 1 154 patients were males (61.8%); the average age of high LDL-C/HDL-C ratio group was (46.5±6.8) years, 1 523 were males (76.4%). The number of target lesions, the number of coronary artery lesions, the preoperative SNYTAX score and the proportion of three-vessel coronary artery disease in the high LDL-C/HDL-C group were significantly higher than those in the low LDL-C/HDL-C group (1.04±0.74 vs. 0.97±0.80, P=0.002; 2.04±0.84 vs. 1.85±0.84, P<0.001; 13.81±8.87 vs. 11.70±8.05, P<0.001; 36.2% vs. 27.4%, respectively, P<0.001). Correlation analysis showed that there was a significant positive correlation between LDL-C/HDL-C ratio and preoperative SYNTAX score, the number of coronary artery lesions, the number of target lesions and whether it was a three-vessel coronary artery disease (all P<0.05). The 2-year follow-up results showed that the incidence of MACCE was significantly higher in the high LDL-C/HDL-C group than that in the low LDL-C/HDL-C group (6.9% vs. 9.1%, P=0.011). There was no significant difference in the incidence of all-cause death, cardiac death, myocardial infarction, stroke, revascularization and bleeding between the two groups. Cox multivariate regression analysis showed that the LDL-C/HDL-C ratio has no correlation with 2-year MACCE, death, myocardial infarction, revascularization, stroke and bleeding events above BARC2 in patients with premature CHD. Conclusion: High LDL-C/HDL-C ratio is positively correlated with the severity of coronary artery disease in patients with premature CHD. The incidence of MACCE of patients with high LDL-C/HDL-C ratio is significantly higher during 2 years follow-up; LDL-C/HDL-C ratio may be an indicator for evaluating the severity of coronary artery disease and long-term prognosis in patients with premature CHD.

Objective: To explore the effects of expanded frontal-parietal pedicled flap in reconstructing cervical scar contracture deformity in children after burns. Methods: A retrospective observational study was conducted. From January 2015 to December 2020, 18 male children with cervical scar contracture deformity after burns who met the inclusion criteria were admitted to Zhengzhou First People's Hospital, aged 4 to 12 years, including 10 cases with degree Ⅱ cervical scar contracture deformity and 8 cases with degree Ⅲ scar contracture deformity, and were all reconstructed with expanded frontal-parietal pedicled flap. The surgery was performed in 3 stages. In the first stage, a cylindrical skin and soft tissue expander (hereinafter referred to as expander) with rated capacity of 300 to 500 mL was placed in the frontal-parietal region. The expansion time was 4 to 6 months with the total normal saline injection volume being 2.1 to 3.0 times of the rated capacity of expander. In the second stage, expander removal, scar excision, contracture release, and flap transfer were performed, with the flap areas of 18 cm×9 cm to 23 cm×13 cm and the secondary wound areas of 16 cm×8 cm to 21 cm×11 cm after scar excision and contracture release. After 3 to 4 weeks, in the third stage, the flap pedicle was cut off and restored. The rated volume of placed expander, total normal saline injection volume, type of vascular pedicle of flap, survival of flap and reconstruction of scar after the second stage surgery were recorded. The neck range of motion and cervico-mental angle were measured before surgery and one-year after surgery. The appearance of neck, occurrence of common complications in the donor and recipient sites of children, and satisfaction of children's families for treatment effects were followed up. Data were statistically analyzed with paired sample t test. Results: All the patients successfully completed the three stages of operation. The rated volume of implanted expander was 300 mL in 6 children, 400 mL in 9 children, and 500 mL in 3 children, with the volume of normal saline injection being 630 to 1 500 mL. The type of vascular pedicle of flap was double pedicle in 13 cases and was single pedicle in 5 cases. All the flaps in 17 children survived well, and the secondary wounds after neck scar excision and contracture release were all reconstructed in one procedure. In one case, the distal blood supply of the single pedicled flap was poor after the second stage surgery, with necrosis of about 2.5 cm in length. The distal necrotic tissue was removed on 10 days after the operation, and the wound was completely closed after the flap was repositioned. In the follow-up of 6 months to 3 years post operation, the cervical scar contracture deformity in 18 children was corrected without recurrence. The flap was not bloated, the texture was soft, and the appearances of chin and neck were good. The range of motion of cervical pre-buckling, extension, left flexion, and right flexion, and cervico-mental angle in one year after operation were improved compared with those before operation (with t values of 43.10, 22.64, 27.96, 20.59, and 88.42, respectively, P<0.01). The incision in the frontal donor site was located in the hairline, the scar was slight and concealed. No complication such as cranial depression was observed in expander placement site, and the children's families were satisfied with the result of reconstruction. Conclusions: Application of expanded frontal-parietal pedicled flap in reconstructing the cervical scar contracture deformity in children after burns can obviously improve the appearance and function of neck, with unlikely recurrence of postoperative scar contractures, thus it is an ideal method of reconstruction.

The present study explored the mechanism of action of Gynostemma pentaphyllum in the treatment of metabolism associa-ted fatty liver disease(MAFLD) by network pharmacology and molecular docking. The main active components and action targets of G. pentaphyllum were collected from TCMSP. Disease-related targets were obtained from GeneCards, OMIM and TTD, and the common targets of the three databases were screened out, which were converted to the genes with standard names by UniProt. The drug-disease common target genes were obtained through Venn tool and uploaded to STRING for the construction of the protein-protein interaction(PPI) network. Cytoscape was used to construct and analyze the drug-active component-common target-disease network. The gene ontology(GO) analysis and Kyoto encyclopedia of genes and genomes(KEGG) pathway enrichment analysis were performed on the common targets by DAVID. Pymol was adopted to perform molecular docking of active components and the common targets and predict their binding ability. Twenty-four active components(such as gypenosides, quercetin and sitosterol) of G. pentaphyllum were screened out. Ninety-two targets were obtained and 54 common targets were identified. Key targets included TNF, IL6, PTGS2, TP53, CCL2 and VEGFA. GO analysis on biological processes, molecular functions and cellular components and KEGG pathway analysis were performed, and the results indicated that NF-κB, PI3 K-Akt, TNF and HIF-1 signaling pathways were mainly involved. Molecular docking results showed that gypenosides and quercetin had a strong binding ability to TNF, IL6 and PTGS2. The findings of this study revealed that the therapeutic efficacy of G. pentaphyllum on MAFLD might be achieved by resisting inflammation and oxidative stress and improving insulin resistance, providing ideas and a theoretical basis for the development and application of G. pentaphyllum in the treatment of MAFLD.

OBJECTIVE: Pyrotinib, a novel irreversible pan-ErbB receptor tyrosine kinase inhibitor, showed promising antitumor activity and acceptable tolerability in phase II and phase III randomized clinical trials. We assessed the activity and safety of oral pyrotinib for human epidermal growth factor receptor 2 (HER2) positive metastatic breast cancer patients in the real world. METHODS: We retrospectively analyzed 72 HER2 positive metastatic breast cancer (MBC) patients who received oral pyrotinib based regimens at Beijing Cancer Hospital and other four hospitals (Peking University First Hospital, China-Japan Friendship Hospital, General Hospital of PLA, Peking University Third Hospital) from August 2018 to September 2019. Progression free survival (PFS), objective response rate (ORR), adverse events (AE) of pyrotinib were investigated. RESULTS: Seventy-two patients with HER2 positive MBC were enrolled. The median age of the patients was 55 years (range: 32-79 years). Sixty-nine (95.8%) patients had received anti-HER2 treatment in the metastatic and/or (neo) adjuvant settings; 61 (84.7%) patients had received anti-HER2 treatments in the metastatic setting in terms of trastuzumab 56 (77.8%) patients, lapatinib 36 (50.0%) patients, and T-DM1 4 (5.6%) patients. Among these 72 patients who received oral pyrotinib based regimens, 62 (86.1%) patients received pyrotinib (±trastuzumab) in combination with chemotherapy, 6 (8.3%) patients received pyrotinib (± trastuzumab) in combination with endocrine therapy and 4 (5.6%) patients received pyrotinib (±trastuzumab). Sixty-five (90.3%) patients received 400 mg pyrotinib once daily as initial dose, and 7 (9.7%) patients received 320 mg. OBJECTIVE response and safety to pyrotinib based therapy were evaluable in all the 72 patients. One (1.4%) patient achieved complete response (CR), 18 (25.0%) patients achieved partial response (PR), 41 (56.9%) patients had stable disease (SD), and 12 (16.7%) patients had progressive disease (PD). The ORR (CR+PR) was 26.4% and the median PFS was 7.6 months (95%CI: 5.5-9.7 months). Among the 36 patients with prior lapatinib therapy, the median PFS was 7.9 months (95%CI: 4.1-11.7 months). Among the 15 patients with brain metastasis, the median PFS was 6.0 months (95%CI: 2.2-9.8 months). The main toxicities related to pyrotinib were diarrhea in 57 (79.2%) cases, and 48 (66.7%) cases with grade 1-2 as well as 9 (12.5%) cases with grade 3. CONCLUSION Pyrotinib based therapy is an effective treatment for patients with HER2 positive MBC, including patients with lapatinib treatment failure and brain metastasis, and the toxicities can be tolerated.

Glaucoma is a group of diseases which can threaten and damage the optic nerve and its visual pathway, leading to visual impairment as a result. Glaucomatous optic neuropathy is a chronic disease accompanied by apoptosis of retinal ganglion cells ( RGCs ) , visual field defect and cupping of optic nerve head. The gold standard in functional glaucoma evaluation is standard automated perimetry ( SAP) , but it is often limited to the subjective feelings of the patients. Still, visual electrophysiological techniques cannot replace the conventional inspection, but with its rapid development, it has provided a new strategy for the early diagnosis of glaucoma as a supplement because it can show changes in amplitude and latency before visual field defect. Here we review three special electroretinograms and multifocal focal visually evoked potentials in the early diagnosis of glaucoma.
