Abstract
Objective: To evaluate the role and molecular mechanism of Nei endonuclease VIII-like protein 3 (NEIL3) in hepatocellular carcinoma (HCC) through The Cancer Genome Atlas database. Methods: RNA sequencing of HCC samples was the first step in determining the level of gene NEIL3 expression in normal tissues and tumors. Then, NEIL3 was used for the Gene Ontology, the Kyoto Encyclopedia of Genes and Genomes, gene enrichment analysis, immune cell infiltration analysis. The samples were divided into high and low expression groups according to the median expression level of NEIL3 in liver cancer tissues. Logistic regression analysis, Kaplan-Meier analysis, univariate and multivariate Cox regression analysis, and a nomogram prognostic model were used to explore the clinical and prognostic significance of NEIL3 in HCC. Results: Compared with normal samples, NEIL3 was highly expressed in most malignant tumors, including HCC (P < 0.05). High expression of NEIL3 was related to cell cycle, DNA replication, and cell receptor pathways. In addition, the high expression of NEIL3 was significantly positively correlated with T-helper 2 lymphocytes and infiltration levels (R = 0.670, P < 0.001). Compared with the NEIL3 low expression group, the NEIL3 high expression group had a higher level of Th2 cell infiltration in tumor tissues (P < 0.001). Logistic regression analysis showed that NEIL3 overexpression was associated with high T stage, high pathological stage, high tissue grade, AFP > 400 μg/L and vascular invasion of HCC. The Kaplan-Meier analysis results showed that overall survival [hazard ratio (HR) = 2.53, P < 0.001)], disease-specific survival (HR = 2.52, P < 0.001), and progression-free interval (HR = 1.82, P < 0.001) in patients with HCC with high NEIL3 expression were unfavorable. Cox regression analysis results showed that high NEIL3 expression was an independent risk factor for an unfavorable prognosis in HCC patients (P = 0.002). The nomogram and calibration chart further demonstrated that high NEIL3 expression was one of the risk factors for an unfavorable prognosis in HCC patients. Conclusion: Elevated expression of NEIL3 is associated with an unfavorable prognosis and an increased proportion of immune cells in HCC, and it is likely to be used as a potential biomarker for evaluating the prognosis and immune infiltration level.

Abstract
Objective: To investigate the clinicopathological features and molecular genetics of diffuse large B-cell lymphomas (DLBCL) with concurrent or secondary to nodal T-follicular helper cell lymphoma, angioimmunoblastic-type (nTFHL-AI). Methods: The clinicopathological features and molecular genetics of DLBCL associated with nTFHL-AI diagnosed between January 2015 and October 2022 at the First Affiliated Hospital of Zhengzhou University were analyzed using histology, immunohistochemistry, PCR, EBV-encoded RNA in situ hybridization and fluorescence in situ hybridization (FISH). Clinical information was collected and analyzed. Results: A total of 6 cases including 3 nTFHL-AI with secondary DLBCL and 3 composite lymphomas were reviewed. There were 4 male and 2 female patients, whose ages ranged from 40 to 74 years (median 57 years). All patients presented with nodal lesions at an advanced Ann Arbor stage Ⅲ/Ⅳ (6/6). Bone marrow involvement was detected in 4 patients. All cases showed typical histologic and immunophenotypic characteristics of nTFHL-AI. Among them, 5 cases of DLBCL with concurrent nTFHL-AI exhibited numerous large atypical lymphoid cells and the tumor cells were CD20 and CD79α positive. The only case of DLBCL secondary to nTFHL-AI showed plasma cell differentiation and reduced expression of CD20. All of cases were activated B-cell (ABC)/non-germinal center B-cell (non-GCB) subtype. Three of the 6 cases were EBV positive with>100 positive cells/high power field, meeting the diagnostic criteria of EBV+DLBCL. The expression of MYC and CD30 protein in the DLBCL region was higher than that in the nTFHL-AI region (n=5). C-MYC, bcl-6 and bcl-2 translocations were not detected in the 4 cases that were subject to FISH. Four of the 6 patients received chemotherapy after diagnosis. For the DLBCL cases of nTFHL-AI with secondary DLBCL, the interval was between 2-20 months. During the follow-up period ranging from 3-29 months, 3 of the 6 patients died of the disease. Conclusions: DLBCL associated with nTFHL-AI is very rare. The expansion of EBV-infected B cells in nTFHL-AI may progress to secondary EBV+DLBCL. However, EBV-negative cases have also been reported, suggesting possible other mechanisms. The up-regulation of MYC expression in these cases suggests a possible role in B-cell lymphomagenesis. Clinicians should be aware that another biopsy is still necessary to rule out concurrent or secondary DLBCL when nodal and extranodal lesions are noted after nTFHL-AI treatment.

Abstract
Objective: To investigate the clinicopathological features and molecular genetics of cyclin D1-negative mantle cell lymphoma (MCL). Methods: The clinicopathological features and molecular genetics of CyclinD1-negative MCL diagnosed between January 2016 and July 2021 at the First Affiliated Hospital of Zhengzhou University were analyzed using immunohistochemistry and fluorescence in situ hybridization. Clinical information was collected and analyzed. Results: A total of five Cyclin D1-negative MCL cases from all 212 MCL patients (5/212, 2.4%)were included. There were three male and two female patients,age ranged from 59 to 70 years (median 64 years). All patients presented with nodal lesions. None of the patients had B symptoms but four had bone marrow involvement. Histopathologically, four cases were classic MCL and one case was pleomorphic variant type. All five cases were negative for Cyclin D1 but SOX-11 were positive in all cases. CD5 was positive in four cases and one case was weakly positive for CD23. CD10 and bcl-6 were negative in all cases. CCND1 translocation was identified in three cases and CCND2 translocation in one case by FISH analysis. However,CCND3 translocations were not found in the five cases. Conclusions: Cyclin D1-negative MCL are uncommon, its accurate diagnosis needs combined analysis with morphologic and immunophenotypic characteristics and genetic changes. It may be particularly difficult to distinguish from other small cell type B cell lymphomas. FISH analyses for CCND1/CCND2/CCND3 translocations and immunohistochemistry for SOX-11 are helpful to resolve such a difficult distinction.

Abstract
Objective: To study the clinicopathological and genetic features of natural killer (NK)-cell enteropathy for better understanding of this rare disease and prevention of its misdiagnosis. Methods: Two cases of NK-cell enteropathy were diagnosed in the First Affiliated Hospital of Zhengzhou University, China from October 2017 to February 2021. The clinical characteristics, morphology, immunohistochemistry, Epstein-Barr virus-encoded RNA (EBER) in situ hybridization and T cell receptor gene rearrangement were analyzed. The patients were followed up by a telephone interview. Results: The patients were both male, aged 40 and 28 years, respectively. Both patients were admitted to the hospital for an annual checkup without obvious gastrointestinal symptoms. The endoscopy showed that the gastric body of case 1 had a mucosal bulge, small area of congestion and erosion, while the rectum of case 2 had congestion and erosion. Microscopically, the lesions of the 2 cases were relatively limited. Many lymphoid cells infiltrated within the lamina propria of the mucosa and into the muscularis mucosa in case 2. In case 1, the glands were reduced in the lesion, and the glandular cavity was slightly compressed and deformed. There was no infiltration or destruction of the glands in either case. Lymphoid cells were atypical, with medium-to-large cell sizes. Their cytoplasm was medium-to-slightly abundant and appeared eosinophilic or translucent. In case 2, characteristic eosinophilic granules were seen in the cytoplasm of a few cells. The nuclei in both cases were round, oval and irregular, with fine chromatin, inconspicuous nucleoli, and no mitotic figures were noted. Necrosis was seen in case 1 while both cases had no central growth or destruction of blood vessels. Immunophenotyping showed that CD56, granzyme B and TIA-1 were positive in both cases, part of the cells was CD3-positive, and some cells were weakly CD4-positive in case 2. The CD5, CD8, CD30, ALK and B-lineage markers (CD20, CD79α) were all negative. The Ki-67 proliferation index was about 60% and 30%, respectively. Both cases were EBER negative. TCR gene rearrangement was polyclonal. Follow-up showed that none of the 2 patients had any special treatments and stayed well. Conclusions: NK-cell enteropathy is rare, with biological behaviors similar to benign tumors, and occasional recurrence. Its histology and immunophenotype are easily confused with NK/T cell-derived lymphomas. Combination of its unique endoscopic features, EBER negativity, polyclonal TCR gene rearrangement and good prognosis can confirm the diagnosis and avoid misdiagnosis and overtreatment.

Abstract
Objective: To investigate the clinicopathological features, molecular genetics, treatment and prognosis of Burkitt-like lymphoma with 11q aberration (BLL-11q). Methods: Six cases of BLL-11q diagnosed at the First Affiliated Hospital of Zhengzhou University, from January 2016 to January 2020 were reviewed and analyzed using hematoxylin-eosin staining, immunohistochemistry, EBER in situ hybridization and fluorescence in situ hybridization. Clinical information including follow-up data was collected and analyzed. Results: The median age of the six immunocompetent patients was 29 years (range 20-38 years) and the male to female ratio was 5∶1. All patients had nodal disease in the head and neck region. Five patients had Ann Arbor stage Ⅰ-Ⅱ disease, while one patient had stage Ⅳ disease. Lymph nodes showed partial or total architectural effacement by a diffuse proliferation of monomorphic lymphocytes. Four cases were morphologically similar to Burkitt lymphoma, and two cases were unclassified with histological features between Burkitt lymphoma and diffuse large B-cell lymphoma. Mitotic figures, apoptosis and necrosis were conspicuous. Five cases exhibited the"starry sky"pattern. CD20, CD10 and bcl-6 were diffusely and strongly positive. The Ki-67 index was more than 95%. The follicular-dendritic-cell meshwork was noted in one case using CD21 stain. C-MYC was expressed variably. CD3, bcl-2, MUM-1, CD30 and TDT were negative in all cases. EBER in situ hybridization was also all negative. FISH analyses using C-MYC, bcl-2 and bcl-6 break-apart probes were all negative. All cases had the 11q23.3 gain/11q24.3 loss pattern, and 11q23.3 amplification was found in one case. IgH and IRF4 break-apart probes analysis was also negative. All patients were alive with no disease after a follow-up of 4 to 19 months. Conclusion: BLL-11q is a rare lymphoma that resembles Burkitt lymphoma morphologically and phenotypically, but lacks C-MYC gene rearrangements. Instead, it has a chromosome-11q alteration characterized by proximal gains and telomeric losses. It's necessary to improve our understanding of BLL-11q to avoid misdiagnosis and missed diagnosis.

Abstract
Objective: To investigate the clinicopathological features and differential diagnosis of primary cutaneous nasal extranodal NK/T cell lymphoma (pcENKTCL-NT). Methods: Fifteen cases of pcENKTCL-NT were collected at the First Affiliated Hospital of Zhengzhou University from January 2016 to December 2019. The clinical characteristics, morphological features, immunophenotypes, and results of in situ hybridization and gene detection were analyzed. Results: Among the 15 patients, 7 were male and 8 were female, with a male to female ratio of 1.0∶1.1. Their ages ranged from 29 to 86 years, and the median age was 59.3 years. All patients were hospitalized for skin lesions, including skin ulcers, scattered patchy red papules, and local blisters. The skin lesion might be a hard nodular mass, and part of it was a confluent patchy erythema; it could be manifested as multiple scattered nodules of different sizes, and some lesions were like round ulceration. There were 8 cases of lower limbs, 4 cases of chest (1 case with upper limb lesions), 2 cases of trunk and 1 case of neck. Most of the patients were sensitive to GGDP regimen (cisplatin, dexamethasone, gemcitabine and pemostatin). Histologically, most lesions showed tumor cells invading the epidermis and skin appendages, dermal infiltration, diffuse distribution, vascular and peritubular destruction, and some subcutaneous adipose tissue involvement. Morphologically, most of the tumor cells were mixed with small-to medium-size lymphocytes, and some were large cells, mixed cells or small cells. Immunohistochemistry showed that CD3, CD3 ε and TIA-1 were expressed in all cases, but not CD20 and CD8. CD56 and granzyme B were expressed in most of the cases, and CD5 was not expressed. Ki-67 positive index was about 50%-90%. EBV in situ hybridization was positive in all cases. The clonal rearrangement of T cell receptor gene was found in some CD56 negative cases. The 15 patients were followed up for 5-45 months, and one of them was lost to follow-up. Five patients died within 5-13 months after the diagnosis, accounting for 35.7% (5/14) of the 14 patients. The average survival time of the deceased patients was 8.6 months. Conclusions: The incidence rate of pcENKTCL-NT is relatively low, but its biological behavior is aggressive and its prognosis is overall poor. Its skin lesions and histopathological features are relatively diverse. The diagnosis should be determined with using clinical data, histological morphology, immunophenotype and EB virus in situ hybridization. At the same time, attention should be paid to differential diagnosis from other cutaneous lymphoma with cytotoxic phenotype to avoid missed diagnosis and misdiagnosis.

Abstract
Objective: To study the clinicopathologic and genetic features of Waldeyer's ring peripheral T-cell lymphoma with follicular helper T cell immunophenotypes (wPTCL-TFH), with comparison to the nodal peripheral T-cell lymphoma with TFH immunophenotypes (nPTCL-TFH) and angioimmunoblastic T-cell lymphoma (AITL), as to know this rare tumor better. Methods: The clinical data, histopathology features, EBV positivity, T cell clonality and IDH2(R172) gene mutation in 8 cases of wPTCL-TFH were collected at the First Affiliated Hospital of Zhengzhou University from December 2015 to April 2019, and analyzed by immunohistochemistry, in situ hybridization, TCR gene rearrangement (BIOMED-2) and Sanger sequencing.Follow-up data were obtained by telephone. Results: There were 6 males and 2 females with a median age of 62.5 years (age ranging from 30 to 75 years). All patients had neither fever nor skin manifestations, but were all found mucosa thickened or mass of waldeyer's ring with multiple lymph nodes enlarged by PET-CT/CT scans. Five of the 7 patients were at advanced stages (Ⅲ/Ⅳ stage). Microscopically, the mucosa was infiltrated diffusely and characteristically by numerous small-medium sized lymphocytes, lacking polymorphous inflammatory background and extra-follicular expansion of follicular dendritic cell networks (FDC networks). The clear T cells presented in 5 cases. Ulcers on mucosal surfaces (6 cases) and local-extensive loss of intramucosal glands (7 cases) were commonly noted. Granulomas composed of epithelioid histiocytes were observed in 2 cases. Immunohistochemically, all the tumor cells expressed CD4 and at least 2 types of follicular helper of T cell (TFH) markers: PD-1 (8/8), bcl-6 (8/8), CXCL13 (7/8) and CD10 (1/8). Most of the cases (6 cases) expressed CD30. EBV positive appeared in 4 cases. All 8 cases were T cell monoclonal. IDH2(R172) were wild-type in 6 cases. One patient died at the follow-up time on 18 months; the other 7 survived (the follow-up time varied from 3 to 10 months). Conclusions: wPTCL-TFH is rare, and its clinicopathological features are similar to nPTCL-TFH which may be the manifestation of the same disease at different stage, and partly overlapped with AITL. The differential diagnosis from PTCL-NOS is necessary and comprehensive analyses of clinical, morphological, immunohistochemical and genetic features can help make a correct diagnosis.

Abstract
Nonalcoholic fatty liver disease (NAFLD) is one of the most common chronic liver diseases in China and manifests as simple fatty liver, non-alcoholic steatohepatitis, liver cirrhosis, and hepatocellular carcinoma. Studies have shown that intestinal flora can affect the development and progression of NAFLD via the "gut-liver axis" . Probiotics are active microorganisms with beneficial effects on the host, and more and more studies have found that probiotics play a positive role in improving NAFLD. They are cheaper, less harmful, and safer compared with antibiotics and surgery, and therefore, it may become a new method for the prevention and treatment of NAFLD. This article reviews the research advances in probiotics in the treatment of NAFLD, in order to provide a basis for the treatment of NAFLD using probiotics.

Abstract
This study aims to investigate the effects of epidural block in combination with general anesthesia and general anesthesia alone on the immune function of patients undergoing primary liver cancer resection. Twenty-four patients with liver cancer who received treatment in the Third Hospital of Harbin Medical University, Heilongjiang, China, were enrolled and randomly allocated into group A and group B, with 12 in each group. The data on the T lymphocyte subpopulation, pro-inflammatory cytokines and antiinflammatory cytokines were recorded before, immediately after and 24 h after liver cancer resection to compare differences and changes. It was found that CD4+ of patients who underwent combined anesthesia decreased after surgery and CD8+ of those patients was lower than that of the general anesthesia group. The content of interleukin (IL)-10 of patients who underwent general anesthesia combined with epidural block showed a decreasing tendency immediately after surgery, but increased 24 h after surgery, and the increase was greater than that of the general anesthesia group; furthermore, those patients had lower levels of IL-1β and interferon (IFN)-γ. In addition, patients who underwent epidural block and general anesthesia had a higher ratio of IFN-γ to IL-4 (Th1/Th2). These findings suggest that general anesthesia combined with epidural block has little passive influence on the cellular immunity of the body and can be selected as an anesthetic approach for patients with liver cancer.

Abstract
OBJECTIVE To investigate the clinical significance of the three-step approach in laparoscopic hemihepatectomy. METHODS A total of 32 patients received laparoscopic hemihepatectomy with the three-step approach in Yijishan Hospital affiliated to Wannan Medical College between Aug 2013 and Oct 2015. All patients underwent thin slice CT scan and hemihepatectomy was imitated with the imagic explorer, preoperatively. The vessel distribution was observed at the section and the three-step approach was used in the hemihepatectomy. Pre- and post-operative data were collected and analyzed retrospectively. RESULTS The length of middle hepatic vein (MHV) was (59.1±12.9) mm and the number of branchs to the left and right lobe were 3.07±0.78 and 3.11±0.64 respectively. The distance between the first branch of MHV and the diaphragmatic surface was (28.07±3.74) mm and the distance between MHV and the visceral surface was (14.4±4.3) mm. The laparoscopic surgeries (left hemihepatectomy in 28 and right hemihepatectomy in 4) were performed successfully in all cases with the three-step approach, without any conversion to the open surgeries. The operation time was (165±42) min in left hemihepatectomy and (305±50) min in right hemihepatectomy. The intraoperative blood loss was (242±65) ml in left hemihepatectomy and (695±122)ml in right hemihepatectomy. All the patients recovered well without severe complications except for bile leakage in 3 patients who were cured with drainage. The postoperative hospital stay was (7.96±1.8) d. CONCLUSIONS the distribution of vessel is regional at the section of hemihepatectomy and the three-step approach based on this feature is safe and effective in laparoscopic hemihepatectomy, which can shorten the operation time and reduce the difficulty of operation.
