ABSTRACT

@#Diagnosis of early keratoconus(KC)contributes to identifying potential patients before typical clinical symptoms. It also contributes to timely intervention of the progress of disease and improvement of long-term prognosis. Hence, it is crucial to prevent iatrogenic corneal ectasia and reduce the burden of keratoplasty. There are diverse kinds of early KC diagnosis techniques, including corneal topography, corneal aberrations, epithelial and corneal thickness measurement, corneal confocal microscopy, corneal biomechanics, and genetic examination. Since it is often difficult to ensure sufficient sensitivity and specificity with single technique, multiple techniques are beneficial to evaluate the cornea comprehensively, which may become the development tendency of early KC diagnosis in the future.

ABSTRACT

Objective To investigate the effects of nitroquine on the development of different stages of Plasmodium yoelii in Anopheles stephensi. Methods An. stephensi mosquitoes were fed with conventional sucrose water or sucrose water containing 100 μmol/L nitroquine one day prior to P. yoelii infection. Following starvation for 24 hours, mosquitoes were fed with the blood of Kunming mice infected with P. yoelii, and the number of oocysts was observed in the stomach of An. stephensi. After 6 days and 14 days of infection, the mosquitoes were starved for 24 hours, and then fed with conventional sucrose water or nitroquine treated sucrose water. The An. stephensi mosquitoes were starved for 24 hours 6 and 14 days post-infection with P. yoelii, and then fed with conventional sucrose water or nitroquine-containing sucrose water, the numbers of P. yoelii sporozoites were examined in the hemolymph and salivary glands of An. stephensi. Results Following exposure to nitroquine-containing sucrose water one day prior to P. yoelii infections, the number of P. yoelii oocysts was significantly lower in the An. stephensi stomach on day 7 (119.2 ± 16.1 vs. 207.3 ± 21.8; t = 3.207, P < 0.05). After conventional sucrose water was ceased for 24 hours on day 6, and An. stephensi was fed with nitroquine-containing sucrose water, the number of P. yoelii sporozoites peaked in the hemolymph on day 14 in the nitroquine treatment group (952.3 ± 22.7) and on day 12 in the sucrose water treatment group (1 287.0 ± 39.0), and there was a significant difference in the number of sporozoites in the salivary glands between the nitroquine treatment group and the sucrose water treatment group (9 467.0 ± 1 304.0 vs. 10 533.0 ± 758.7; t = 0.707, P = 0.506) on day 17. After conventional sucrose water was ceased for 24 hours on day 14, and An. stephensi was fed with nitroquine-containing sucrose water, the number of sporozoites in the salivary glands was significantly greater in the nitroquine treatment group than in the sucrose water treatment group (21 900.0 ± 2 613.0 vs. 10 533.0 ± 732.3; t = 4.188, P < 0.05). Conclusions Nitroquine treatment exhibits diverse effects the development of different stages of P. yoelii, and nitroquine treatment may reduce the transmission of P. yoelii in uninfected An. stephensi.

ABSTRACT

Objective: To identify the active ingredients, potential targets, and mechanism of Rhizoma coptidis by bioinformatics method, and to explore the hypoglycemic effect of Rhizoma coptidis by in vitro experiments. Methods: The chemical components of Rhizoma coptidis were collected through database search, and oral bioavailability and drug-likeness were used for preliminary screening. The targets of Rhizoma coptidis and diabetes-related targets were collected by database retrieval and reverse docking techniques, and the biological process of cross-set proteins was analyzed. The inhibitory effects of Rhizoma coptidis on α-glucosidase, α-amylase activity, and advanced glycation end products (AGEs) were determined via in vitro experiments. In addition, the effects of Rhizoma coptidis on pre-adipocyte differentiation, absorption of glucose by adipocytes, and the level of intracellular triglyceride were investigated using the adipocyte differentiation model. Results: There were 11 potentially active ingredients in Rhizoma coptidis. IL-6, caspase-3, epidermal growth factor receptor (EGFR), MYC, and estrogen receptor 1 were considered as the key genes. The bioinformatics analysis showed that Rhizoma coptidis played an anti-diabetic role mainly via biological processes and signaling pathways including hormone receptor activity, glutathione binding, steroid binding, etc. In vitro experiments showed that the extract of Rhizoma coptidis inhibited the activities of α-glucosidase and α-amylase, and the generation of AGEs; meanwhile, the extract promoted the absorption of glucose by adipocytes. In addition, the extract of Rhizoma coptidis decreased triglyceride level. Conclusions: Our network pharmacology and in vitro experiments demonstrate the anti-diabetic effects and possible underlying mechanisms of Rhizoma coptidis extract.

ABSTRACT

Selective activation or inhibition of the angiotensin II type 2 (AT2) receptor can cause vasodilation, decrease cell proliferation, promote neurite outgrowth and block neuronal excitability. The AT2 receptor can be used as a potential drug target for the treatment of cardiovascular diseases, fibrosis, inflammation, neuronal diseases and tumors. Research and development of new drugs that selectively act on the AT2 receptor and the mechanism of intracellular signal transduction involving the AT2 receptor is a challenging but worthy endeavor. We review research progress on the AT2 receptor and compounds that act on the AT2 receptor, along with structure-activity relationship analysis, to provide reference and guidance for further research in this field.

ABSTRACT

The current study was designed to evaluate the modulatory effects of paeoniflorin on the dysregulated gut microbiota as well as the disturbed fecal bile acids (BAs) in colitis mice. After approved by Xi'an Jiaotong University Ethics Committees (Approval No. XJTU2019-679), the animals were randomly distributed into the control (Con), colitis, low dose paeoniflorin (PF-L, 25 mg·kg-1·d-1), high dose paeoniflorin (PF-H, 50 mg·kg-1·d-1) and 5-aminosalicylic acid (5-ASA, 50 mg·kg-1·d-1) groups. Colitis was induced by administering 3% (w/v) DSS in drinking water for 7 days. Paeoniflorin and 5-ASA were dissolved in water and administered to the appropriate groups by oral gavage over the 7-day period. The mice were monitored daily, and the disease activity index (DAI) comprising of body weight loss, stool consistency and gross blood was measured. The pathological changes of colon were evaluated by HE staining; the levels of inflammatory cytokines in colonic tissue were determined by ELISA; the gut permeability was measured by FITC-dextran. Microbiota analysis based on 16S rDNA and targeted metabolomics for BAs were used to evaluate the composition of gut microbiota and fecal BAs pool. The results showed that administration of paeoniflorin markedly alleviated the inflammatory response and intestinal barrier dysfunction in DSS-induced colitis. Importantly, these ameliorative effects of paeoniflorin were accompanied by the improvements of disturbed composition of gut microbiota and the dysmetabolism of bile acids in feces. Finally, we performed Spearman's correlation analysis between the fecal BAs and gut microbiota genera, and found that Lactobacillus has a strong positive correlation with DCA and LCA which were reported to confer the beneficial effects of maintaining intestinal homeostasis. Taken together, paeoniflorin might improve the intestinal homeostasis in colitis mice via modulating gut microbiota and fecal BAs metabolism.

ABSTRACT

Objective:To investigate the clinical features and treatment outcome of Kallmann syndrome(KS) caused by fibroblast growth factor receptor-1(FGFR1) gene mutation in 4 patients.Methods:Targeted next-generation sequencing(NGS) was performed on thirty KS and normosmic idiopathic hypogonadotropic hypogonadism(nIHH) patients. FGFR1 mutation was identified in four KS patients. The clinical data, laboratory and imaging examinations, and treatment outcome were retrospectively analyzed.Results:Four male patients, aging from 11 to 22 years old, presented as micropenis, and with olfactory dysfunction. Among them, two had history of cryptorchidism, three had history of cleft lip and palate repair surgery. The most severe patient presented with short stature, left microtia and dental agenesis. FGFR1 heterozygous mutation was identified in all four patients, two were point mutation(p.Y374X; p. E670K), and the other was frameshift mutation(p.S346Yfs*61; p.S723*fs*1). One patient, who started treatment of the pulsatile GnRH pump during his youth, succeeded in having two babies.Conclusion:Patients with Kallmann syndrome caused by FGFR1 mutation presents complex clinical manifestations. Besides dysosmia, micropenis, microrchidia, and delayed pubertal development are the main clinical manifestations in male patients. Symptoms such as cleft lip and palate are helpful for early recognition. Genotyping analysis is crucial to confirm the diagnosis. The pulsatile GnRH pump can produce satisfactory therapeutic effect, but the age of initiating therapy should be carefully considered.

ABSTRACT

With the increasing incidence of hepatobiliary diseases, it is particularly important to understand the role of molecular, cellular and physiological factors in the clinical diagnosis and treatment with traditional Chinese medicine(TCM) in the development of liver disease. Appropriate animal models can help us identify the possible mechanisms of relevant diseases. Danio rerio(zebrafish) model was traditionally used to study embryonic development, and has been gradually used in screening and evaluation of liver diseases and relevant drug in recent years. Zebrafish embryos develop rapidly and the digestive organs of 5-day-old juvenile fish are all mature. At this stage, they may develop hepatobiliary diseases induced by developmental defects or compounds. Zebrafish liver is similar to human liver in cell composition, function, signal transduction, response to injury and cell process mediating liver disease. Furthermore, due to the high conservation of genes and proteins between humans and zebrafish, zebrafish becomes an alternative system for studying basic mechanisms of liver disease. Therefore, genetic screening could be performed to identify new genes involving specific disease processes, and chemical screening could be made for drugs in specific processes. This paper briefly introduced the experimental properties of zebrafish as model system, emphasized the study progress of zebrafish models for pathological mechanism of liver diseases, especially fatty liver, and drug screening and evaluation, so as to provide ideas and techniques for the future liver toxicity assessment of TCM.

ABSTRACT

Objective:To investigate the effect and mechanism of short-chain fatty acids (SCFAs) on the side-effect of tacrolimus on blood glucose.Methods:The C57BL/6 mice were treated with tacrolimus orally (10 mg/kg, tacrolimus group), tacrolimus plus 150 mmol/L sodium butyrate and isovalerate mixed solution (SCFAs group), broad-spectrum antibiotics (antibiotic group), and tacrolimus plus broad-spectrum antibiotics (tac&abx group). After 8 weeks intervention, the fasting blood glucose (FBG), oral glucose tolerance test (OGTT), hemoglobin A1C (HbA1c) were tested as indicators of glucose metabolism, and the gut microbiota, SCFAs concentration in the ileocecal, serum glucagon-like peptide-1 (GLP-1), fasting serum insulin, and GLP-1 expression in intestinal mucosa were performed for intestinal-glucose metabolism mechanism.Results:The FBG and HbA1c were significantly increased in tacrolimus group[(7.31±0.97)mmol/L, (8.34±1.12)%] than control group [(5.23±0.30)mmol/L, (4.32±0.80)%, all P<0.05], which remained normal in antibiotic group [(4.92±0.31)mmol/L, (5.61±0.98)%)], tac&abx group[(5.95±0.37)mmol/L, (4.56±0.26)%] and SCFAs groups [(5.87±0.68)mmol/L, (5.07±1.79)%]. The OGTT in the tacrolimus group showed glucose tolerance impairment, while other groups remained normal. The ileocecal butyric acid and isovaleric acid concentrations in the tacrolimus group were (722.3±262.2) μg/g and (10.0±5.1)μg/g, lower than the control group[ (1 321.3±165.5) μg/g, (19.7±3.6)μg/g, P<0.05]. The above acids in the SCFAs group remained normal as in the control group [(1 375.7±451.6) μg/g, (24.5±11.5)μg/g)]. The fasting serum insulin in the tacrolimus group decreased significantly to (3.2 ± 0.6)mIU/L, compared with control[ (4.4±0.9) mIU/L]and SCFAs groups [(7.0±1.1) mIU/L]. The GLP-1 test indicated a significant decrease in the tacrolimus group[ (4.7±2.9)pg/ml, P<0.05] compared with the SCFAs group and control group [(42.5±19.9) pg/ml, (33.1±9.1) pg/ml]. Conclusions:Tacrolimus affects glucose metabolism through the SCFAs-associated GLP-1 pathway in the intestine, and oral supplementation with mixed SCFAs provides a new insight for the prevention and treatment of tacrolimus-induced hyperglycemia in transplant recipients.

ABSTRACT

Objective:To investigate the effects of curdione on the proliferation, apoptosis and cell cycle of triple negative breast cancer cell line MDA-MB-231. Method:MDA-MB-231 cells were cultured<italic> in vitro</italic> with capecitabine (positive control) and curdione at different concentrations (125, 250, 500, 1 000, and 2 000 μmol·L<sup>-1</sup>), respectively, for detecting their viability using the cell counting kit-8 (CCK-8) at 24 and 48 h. Three effective inhibitory concentrations (250, 500, and 1 000 μmol·L<sup>-1</sup>) against cell proliferation were selected for subsequent experiments. The effect of curdione on cell cycle was determined by flow cytometry combined with propidium iodide (PI) staining. After the set-up of high-concentration (2 000 μmol·L<sup>-1</sup>) group, the effect of curdione on cell mitochondrial membrane potential was measured by JC-1(5,5,6,6-tetrachloro-1,1,3,3-tetraethylbenzimidazolylcarbocyanine iodide) staining, followed by the detection of cell apoptosis by flow cytometry combined with Annexin V-FITC/PI double staining. The changes in cell cycle status and apoptosis-related protein expression following curdione intervention were assayed by Western blot. Result:Compared with the blank control, curdione at 250, 500, 1 000, and 2 000 μmol·L<sup>-1 </sup>significantly inhibited the proliferation of MDA-MB-231 cells (<italic>P</italic><0.01), exhibiting a concentration- and time-response relationship. The half maximal inhibitory concentration (IC<sub>50</sub>) values at 24 and 48 h were 1 607 and 1 401 μmol·L<sup>-1</sup>, respectively. Curdione at 250, 500, and 1 000 μmol·L<sup>-1</sup> arrested cells in G<sub>1</sub> phase. Curdione at 250 μmol·L<sup>-1 </sup>had no effect on cell mitochondrial membrane potential, which, however, declined significantly in the 500, 1 000, and 2 000 μmol·L<sup>-1 </sup>groups (<italic>P</italic><0.05, <italic>P</italic><0.01). Curdione at 250, 500, and 1 000 μmol·L<sup>-1 </sup>obviously increased the proportion of apoptotic cells (<italic>P</italic><0.05, <italic>P</italic><0.01). Curdione at each concentration elevated the Bcl-2-associated X protein (Bax)/B-cell lymphoma 2 (Bcl-2) ratio (<italic>P</italic><0.05, <italic>P</italic><0.01), but did not change the cysteinyl aspartate-specific protease-3 (Caspase-3) expression. The protein expression levels of Caspase-9, cleaved Caspase-9, cleaved Caspase-3, p53, and p21 were up-regulated (<italic>P</italic><0.05). Conclusion:A certain concentration of curdione inhibits the proliferation of MDA-MB-231 cells, which may be related to its efficacy in arresting cell cycle and inducing apoptosis.

ABSTRACT

Ovarian cancer is a kind of malignant tumor in female reproductive system with a high incidence. This disease is insidious at its early stage and the symptoms are not typical. Most of the patients have reached advanced stage by the time of diagnosis, seriously threating women's life and health. Many signaling pathways are involved in the formation and development of ovarian cancer, among which the phosphatidylinositol 3-kinase(PI3K)/protein kinase B(Akt) signaling pathway is one of the key regulatory pathways. In recent years, traditional Chinese medicine (TCM) has obtained wide attention in treatment of tumors due to its advantages of high safety and less adverse reactions, and more and more attention has been paid to the study of TCM monomers. Molecular biology studies have shown that TCM monomers can play a role against tumor by regulating multiple targets. By reviewing the literature and searching several databases, we found that TCM monomer can play an important role in the growth, proliferation, invasion and migration, apoptosis, autophagy and reversal of drug resistance of ovarian cancer cells by regulating PI3K/Akt signaling pathway. According to the existing studies, TCM monomers have a certain effect on ovarian cancer, but there are still many problems. Although the mechanisms of some TCM monomers have been clarified in the treatment of ovarian cancer, such TCM monomers are only limited to the tumor-bearing nude mice in vivo and experimental studies on in vitro cells, and further studies are needed in the future. In addition, in the future researches, ovarian cancer syndrome differentiation and targeted therapy can be linked to the TCM flavors, efficacy and indications to further develop the advantages of TCM. Based on the current research situation at home and abroad, this paper summarized the research progress of targeted intervention of TCM monomers in ovarian cancer by regulating PI3K/Akt signaling pathway, in order to provide reference for further research of TCM monomers, and provide important ideas for the development of targeted treatment of ovarian cancer with TCM.

ABSTRACT

Human leukocyte antigen (HLA) sensitization has been previously considered as a contraindication for kidney transplantation. In the past 30 years, with the development of desensitization therapy strategies and immunosuppressants, more and more highly sensitized patients have been eligible for kidney transplantation. However, highly sensitized patients still face a high incidence of hyperacute rejection and antibody-mediated rejection following kidney transplantation, which restricts the success of kidney transplantation and long-term graft survival. At present, exploring effective desensitization regimen is a hot spot in the research of organ transplantation. In this article, the current desensitization therapy strategies, new preparations for desensitization therapy, and the benefits and risks of desensitization therapy were reviewed, and the current status and future direction of desensitization therapies were investigated, aiming to provide reference for resolving the immune barrier, improving the success rate of kidney transplantation and enhancing the quality of life of highly sensitized recipients.

ABSTRACT

To systematically evaluate the clinical efficacy of 14 oral Chinese patent medicines combined with Azithromycin in the treatment of mycoplasma pneumonia in children with network Meta-analysis. Computer retrieval was performed for such databases as CNKI, VIP, Wanfang, CBM, PubMed, EMbase and Cochrane Library to screen out randomized controlled trials of oral Chinese patent medicines combined with Azithromycin in the treatment of mycoplasma pneumonia in children from the time of database establishment to September 2020. The included studies were evaluated by the Cochrane Risk Assessment tool. Stata 14.0 and Review Manager 5.3 software were used for data statistical analysis. A total of 60 RCTs were included in this study, involving 14 oral Chinese patent medicines. The efficacy ranking based on network Meta-analysis was as follows:(1)in terms of total effective rate, top five Chinese patent medicines in surface under the cumulative ranking curve(SUCRA) were Xiao'er Xiaoji Zhike Oral Liquid, Xiao'er Chiqiao Qingre Granules, Xiao'er Feike Granules, Pudilan Xiaoyan Oral Liquid and Lanqin Oral Liquid;(2)in terms of antifebrile time, top five Chinese patent medicines in SUCRA were Huaiqihuang Granules, Xiao'er Magan Granules, Xiao'er Kechuanling Granules/Oral Liquid, Shuanghuang-lian Oral Liquid for children and Xiao'er Xiaoji Zhike Oral Liquid;(3)in terms of cough disappearance time, top five Chinese patent medicines in SUCRA were Xiao'er Magan Granules, Huaiqihuang Granules, Xiao'er Chiqiao Qingre Granules, Xiao'er Feire Kechuan Oral Liquid and Xiao'er Kechuanling Granules/Oral Liquid;(4)in terms of rale disappearance time, top five Chinese patent medicines in SUCRA were Xiao'er Magan Granules, Huaiqihuang Granules, Xiao'er Feire Kechuan Oral Liquid, Shuanghuanglian Oral Liquid for children and Yupingfeng Granules. The results showed that on the basis of the use of Azithromycin, combined administration with oral Chinese patent medicines could improve the overall clinical efficacy in the treatment of mycoplasma pneumonia in children. However, due to the large differences in the quality and the number of included studies among various therapeutic measures, the ranking results of SUCRA of Chinese patent medicines need to be verified by high-quality multi-center, large-sample, randomized double-blind trials in the future.

Objective:To analyze the correlation between disorganization of retinal inner layers (DRIL) and visual prognosis after pars plana vitrectomy (PPV) in patients with proliferative diabetic retinopathy (PDR).Methods:A retrospective observational systematic cases study. From January 2019 to January 2020, 52 patients (58 eyes) with PDR who were treated with PPV in the department of ophthalmology of The First Affiliated Hospital of Anhui University of Science & Technology were included in the study. There were 24 males (29 eyes) and 28 females (29 eyes), aged from 45 to 80 years old, with the mean age of 62.95 ±9.38 years. All patients were examined BCVA by using international standard visual acuity chart, and the results were converted into logMAR visual acuity in stastistics. The mean preoperative logMAR BCVA was 2.51±0.69. All patients underwent 23G standard PPV by the same physician. Spectral domain-OCT (SD-OCT) was performed to measure DRIL length within 1 mm of macular area diameter, ellipsoid zone (EZ) fracture length and foveal retinal thickness (CMT) one month after operation. According to the length of DRIL, the patients were divided into three groups: non-DRIL group, DRIL≤500 μm group and DRIL> 500 μm group. The differences of BCVA and the SD-OCT parameters were compared among the three groups after PPV. The postoperative BCVA of the three groups were compared by Kruskal-Wallis H test, and the pairwise comparison between the three groups were performed by Bonferroni correction method. Wilcoxon rank sum test was used to compare BCVA in each group at 1 and 6 months after operation. Spearman rank correlation analysis was used to analyze the correlation between BCVA and measurement parameters of SD-OCT at 1, 3 and 6 months after operation. Multivariate stepwise regression analysis was used to analyze the related factors of visual prognosis after operation. Results:At 1 month after operation, the differences in DRIL length ( χ2=52.194, P=0.000) and EZ fracture length ( F=9.558, P=0.000) among the three groups were statistically significant, but there was no significant difference in CMT ( F=0.817, P =0.447). At 1 and 3 months after operation, there were no significant differences in BCVA between the non-DRIL group and the DRIL≤500 μm group ( Z=-1.846, -2.224; P=0.195, 0.078), however, the BCVA of patients in non-DRIL group was better than that of patients in DRIL≤500μm group at 6 months after operation, and the difference was statistically significant ( Z=-2.508, P=0.036). The BCVA of patients in non-DRIL group at 1, 3 and 6 months after operation was better than that of patients in DRIL> 500 μm group, and there were significant differences ( Z=-5.992, -6.275, -6.497; P<0.01). The BCVA of the DRIL≤500 μm group was better than the DRIL> 500 μm group, and the differences were statistically significant ( Z=-4.260, -4.161, -4.099; P<0.01). The comparison of intra-group among the three groups showed that the BCVA of the non-DRIL group and the DRIL ≤ 500 μm group at 6 months after operation were higher than that at 1 month after operation, and the differences were statistically significant ( Z=-3.525, -3.420; P<0.01). There was no significant difference in BCVA between 6 months after operation and 1 month after operation in DRIL> 500 μm group ( Z=-0.422, P=0.673). The results of Spearman rank correlation analysis showed that a strong correlation was between the length of DRIL and logMAR BCVA at 1, 3 and 6 months after operation ( r s=0.896, 0.918, 0.940; P<0.01). The rupture length of EZ was moderately correlated with logMAR BCVA at 1, 3 and 6 months after operation ( r s=0.488, 0.502, 0.521; P<0.05). There was no significant correlation between CMT and logMAR BCVA at 1, 3 and 6 months after operation ( r s=0.243, 0.220, 0.193; P>0.05). Multivariate stepwise regression analysis showed that DRIL length was the main predictor of postoperative visual acuity recovery ( R2=0.703, P=0.000). Conclusion:The length of DRIL and the rupture length of EZ are correlated with the visual prognosis of patients with PDR after PPV, and there is a strong correlation between DRIL and postoperative visual acuity.

ABSTRACT

Objective:To evaluate the interobserver variation of pathologists in the morphological evaluation of non-invasive follicular thyroid neoplasm with papillary-like nuclear features(NIFTP).Methods:Nine pathologists from different regions in China were selected to evaluate the digital slides of 30 cases of NIFTP. Three score system was applied, including nuclear size and shape, membrane irregularity, and chromatin features. Individual histologic features were scored as either present(1)or absent(0). A total score of 0 or 1 was considered inadequate for the diagnosis of NIFTP and a total score of 2 or 3 was considered sufficient for the diagnosis of NIFTP.Results:Overall, 9 doctors had weak consistency in the interpretation of the 30 cases(Kappa value 0.081 4), in which the interpretation of the membrane irregularity had the best consistency(Kappa value 0.193 6)and the interpretation of nuclear size and shape revealed the worst consistency(Kappa value 0.102 2). The overall consistency of the evaluation from the 7 senior pathologists was better than that of all the pathologists(Kappa value 0.134 1), but it was still weak. The consistency of nuclear membrane irregularity(Kappa value 0.267 4)and nuclear chromatin features(Kappa value 0.257 3)was weak, but much better than that of nuclear size and shape(Kappa value 0.073 0). The interobserver consistency in our study was lower than that in Asian study generally. However, the judgement on membrane irregularity in our senior pathologists was better than that in Asian study.Conclusion:The interobserver variation on the evaluation of the nuclear features of NIFTP is probably due to the education level, working experience, personal understanding of the diagnostic criteria, the regional difference, and some uncertain reasons. There is overall a weak consistency in the interpretation of NIFTP by Chinese pathologists, and it is necessary to popularize the diagnostic criteria and specify the criteria in detail. It is important to exclude high-risk genetic mutation using immunohistochemical staining or molecular examination on those patients with morphology of NIFTP.
