Objective: To study the correlation among genetic polymorphism of glutathione S-transferases (GST) T1, M1 and serum creatinine levels,as well as intact parathyroid hormone (PTH) levels in the end stage of renal disease(ESRD). Methods: 118 blood samples of ESRD and 133 of healthy control had been enrolled, and simultaneously the patients' serum creatinine (SCr), blood uria nitrogen (BUN), serum calcium and serum phosphorus were recorded. Polymerase chain reaction (PCR) had been employed to determine the genotypes of GST and immunoradiometric assay was used to determine PTH levels. Results: The distribution frequencies of dual null GST T1 and M1(A), null GST T1 and functional M1 (B), functional T1 and null GST M1(C) and dual functional GST T1 and M1(D) were 16.9%, 11.0%, 44.9%, 27.1% in ESRD and 14.4%, 10.8%, 46.7%, 28.1% in the healthy control, respectively. There was no difference between the two groups (P=0.945); Mean SCr levels of A was higher than that of B (P=0.047) and C (P=0.007) group in ESRD. Conclusion: Distributions of GST Genotypes had no difference among ESRD and healthy control groups; SCr level of dual null GST T1 and M1 (A) was higher than single null GST (B and C) in ESRD. GST may played some roles in metabolism of poisons and protecting cells from the attack of toxic substances.

This paper presents a 3mm fracture model of radial bone of rabbits using operation method. The bone defect was treated with collagen sponge with different pH and different content. After the operation, the body temperature, blood routine measurement, serum antibody, X-ray examination and histological observation in each group were examined to evaluate and study the curative effect and safety of collagen sponge. Collagen sponge had a good result of safety, but there was slightly change in blood routine, serum antibody, and histological observation, etc, with the pH changing and different content of collagen. The results showed that there was no obvious influence of safety to tissues after treatment of the collagen sponge at different pH implanted into bone defect. Collagen sponge at lower pH could promote the healing of bone defect partly, while the safety of collagen sponge with lower content was better.

Objective To study the feasibility and value of magnetic resonance diffusion tensor imaging (DTI) to monitor non?arteritic anterior ischemic optic neuropathy (NAION). Methods Thirty eight NAION patients (56 eyes) were divided into acute period in 17 eyes, progressive period in 16 eyes and chronic period in 23 eyes at the base of onset time. According to matching principle, 56 eyes in 38 normal controls (NCs) were enrolled. All the patients and NCs underwent MR and DTI scan. The raw data were processed by two experienced radiologists, mean diffusivity (MD), axial diffusivities (λ//), radial diffusivities (λ┴), fractional anisotropy (FA) and Length value were got. The independent sample t test was used for the parameter values between the NAION group and the NCs group. A single factor variance analysis was used to compare the parameters among different stages of NAION group. Results Compared to the NCs group, the values of FA and Length in NAION group were reduced [0.20±0.11 vs 0.31±0.12, (5.85±0.92) vs (65.11± 6.89) mm], and the differences were statistically significant (t=-4.28,-5.25;P<0.05). The values of MD andλ┴were increased [(0.16±0.04)×10-3 vs (0.10±0.04)×10-3 mm2/s, (0.16±0.05)×10-3 vs (0.09±0.03)×10-3 mm2/s] in NAION group and the differences were statistically significant (t=6.83, 7.10;P<0.05). The value of FA and Length in acute period, progressive period and chronic period of the NAION group decreased differently compared to the NCs group. At the same time, the value of MD value and λ┴in the three periods of the NAION group increased compared to the NCs groupand the differences were statistically significant (P<0.05). The value of FA between the acute period, the progressive period, and the chronic period of NAION group were statistically signficant (F=10.88, P<0.05). However, no significant differences were found in the values of MD, λ┴and Length of the NAION group (F=0.23, 0.64, 0.33, 1.38;P=0.79, 0.54, 0.72, 0.27). Conclusion The parameters of DTI can be used to monitor the damage of optic nerve and development in NAION.

Objective:To investigate the familial inheritances, clinical features, treatments and outcomes of familial Waldenstrom macroglobulinemia (WM) patients.Methods:The clinical manifestations, laboratory examinations, diagnosis and treatments, and follow-up data of 6 familial WM patients who were admitted to Yancheng No.1 People's Hospital from June 2002 to July 2019 were retrospectively analyzed, and the literature was reviewed.Results:Among 6 WM patients, 4 patients had dizziness and fatigue at the onset, 1 patient had recurrent low-grade fever and abnormal sweating as the first manifestations, 1 patient was hospitalized due to pulmonary infection, and WM was found later. Two brothers of the patients were diagnosed with WM, another 2 brothers of the patients had IgM-type monoclonal gammopathy of undetermined significance (MGUS) during the physical examination. All the 6 patients were middle-aged/elderly men, with a median age of 63 years old (51-70 years old). The median follow-up time were 71.5 months (4-217 months), and by the end of the follow-up (June 2020), 2 cases died of pulmonary infection, and 1 of them developed acute myeloid leukemia; the other 4 cases were in regular chemotherapy. Two IgM-MGUS patients were followed up without symptoms.Conclusions:WM patients have familial aggregation, and their clinical manifestations are highly heterogeneous. Patients with family history may have poor prognosis. It is necessary to strengthen the awareness of WM and family history screening.

Objective:To investigate the expression of Toll-like receptor 8 (TLR8) in diffuse large B-cell lymphoma (DLBCL) and its correlation with clinicopathological characteristics and prognosis of patients.Methods:The data in the Oncomine database was used to analyze the difference of TLR8 mRNA expression between DLBCL tumor tissues and normal lymphocytes, and the result was verified in two independent subsets GSE 25638 and GSE 32018 of the NCBI-GEO database. The OSDLBCL online survival analysis tool was used to analyze the correlation of TLR8 mRNA relative expression level with overall survival (OS) and progression-free survival (PFS) of DLBCL patients. Gene ontology bioprocess (GO_BP) enrichment analysis was performed by using GSEA software. The correlation of TLR8 mRNA expression with tumor immune cell infiltration degree and immune checkpoint-related molecule expression was analyzed by TIMER online tool website. A total of 53 DLBCL patients who underwent lymph node biopsy in Yancheng No. 1 People's Hospital from June 2020 to June 2021 were selected. Immunohistochemistry was used to detect the expression of TLR8 protein, and its relationship with the clinicopathological characteristics of patients was analyzed.Results:The analysis result of data from Oncomine and GEO databases showed that the relative expression levels of TLR8 mRNA in tumor tissues of patients with DLBCL or activated B cell-like DLCBL were higher than those in normal lymphocytes (all P < 0.001). The results of OSDLBCL online survival analysis indicated that the OS ( P = 0.020) and PFS ( P = 0.004) in DLBCL patients with high TLR8 mRNA expression were worse than those in patients with low TLR8 mRNA expression. The level of TLR8 was related to the abnormal function of immune response, cytokine metabolism and DNA damage monitoring; the result of TIMER online analysis showed that the expression level of TLR8 mRNA was positively related to the degree of neutrophil infiltration ( r = 0.78, P < 0.001) and the expression of immunosuppressive molecules [HAVCR2 ( r = 0.85, P < 0.001), LAG3 ( r = 0.63, P < 0.001), CD274 ( r = 0.77, P < 0.001), TIGIT ( r = 0.32, P = 0.037), and C10ORF54 ( r = 0.34, P = 0.029)]. Among 53 DLBCL patients, 29 patients (54.7%) had low expression of TLR8 protein and 24 patients (45.3%) had high expression of TLR8 protein. There were statistical differences in the expressions of TLR8 protein in DLBCL patients with different serum lactate dehydrogenase and β 2-microglobulin levels (both P < 0.05). Conclusions:TLR8 is highly expressed in DLBCL patients, and TLR8 may be a prognostic marker of DLBCL.

Objective:To investigate the clinicopathological features, diagnosis, differential diagnosis and treatment of nodal marginal zone lymphoma (NMZL) with elevated monoclonal IgM.Methods:The clinical data of one NMZL patient with elevated monoclonal IgM treated at Yancheng No.1 People's Hospital in July 2020 were retrospectively analyzed, and the related literature was analyzed.Results:The patient was a 57-year-old female and the main clinical manifestations were fatigue and bone pain in left rib. Serum immunofixation electrophoresis showed IgM-κ type M proteinemia, bone marrow cytology showed a few plasmacytoid lymphocytes, bone marrow biopsy and immunohistochemistry showed B-cell non-Hodgkin lymphoma, bone marrow genetic testing showed MYD88 L265p and CXCR4 were both negative, postoperative pathology result of retroperitoneal lymph node biopsy was marginal zone lymphoma (mature small B type, prone to NMZL),and immunohistochemistry results: CD3, CD5, CD138, κ, λ, CD10, Cyclin D1 were negative, CD20, Pax-5, CD23 (FDC), bcl-2 were positive; Ki-67 positive index < 5%. The final diagnosis was NMZL with elevated monoclonal IgM. Partial remission was achieved after 8 cycles of reduced-dose CHOP regimen; thalidomide was used in the maintenance treatment, the disease condition was stable until August in 2021 and the follow-up was continuing.Conclusions:NMZL with elevated monoclonal IgM is relatively rare. Its diagnosis should be differentiated from Waldenstr?m macroglobulinemia and other inert B-cell lymphomas. Currently, there is no standard treatment and following the principle of individualized treatment can improve the prognosis of patients.

Objective:To explore the risk factors of bortezomib-related peripheral neuropathy (BIPN) and the clinical and electrophysiological characteristics of patients in treatment of multiple myeloma (MM).Methods:The clinical data of 71 newly diagnosed MM patients treated with BD (bortezomib + dexamethasone) regimen in Yancheng First People's Hospital from March 2016 to December 2019 were retrospectively analyzed. The bone marrow morphology, immunology, cytogenetics, molecular biology (MICM), routine electrophysiological examination before and after treatment were performed. All patients were divided into the peripheral neuropathy (PN) group and the non-PN group according to the presence or not of BIPN, and the clinicopathological differences of both groups were also compared; a binary logistic regression model was used to analyze the factors affecting the occurrence of PN. The electrophysiological characteristics were summarized and fluorescence in situ hybridization (FISH) was used to detect karyotype of BIPN patients.Results:Among 71 MM patients, there were 40 cases (56.3%) of PN and 31 cases (43.7%) of non-PN. The proportion of patients at international staging system (ISS) staging Ⅲ, and the levels of IgA, IgG, IgM, serum creatinine, β 2-microglobulin (β 2-MG) in the PN group were higher than those in the non-PN group, and hemoglobin (Hb) level in the PN group was lower than that in the non-PN group, and the differences were statistically significant (both P < 0.05). Binary logistic regression analysis showed that increased IgA ( OR = 1.151, 95% CI 1.012-1.309, P = 0.033), increased IgG ( OR = 1.055, 95% CI 1.000~1.112, P = 0.049), increased IgM ( OR = 1.010, 95% CI 1.001-1.018, P = 0.022), increased serum creatinine ( OR = 1.037, 95% CI 1.011~1.065, P = 0.005), increased β 2-MG ( OR = 1.564, 95% CI 1.039-2.354, P = 0.032) were risk factors for BIPN. Among 40 patients with BIPN, 33 cases (82.5%) of sensory nerve conduction velocity (SCV) were abnormal, 23 cases (57.5%) of motor nerve conduction velocity (MCV) were abnormal; 31 cases (77.5%) showed demyelination damage, 9 cases (22.5%) had axonal damage. Among 40 patients with BIPN, 24 cases underwent FISH detection, including 19 cases (79.2%) with chromosomal mutations, of which 12 cases (50.0%) were mixed subtype abnormal. Conclusions:MM patients with high levels of β 2-MG, IgA, IgG, IgM and serum creatinine are more prone to PN when treated with bortezomib. The electrophysiology of patients with BIPN is mainly characterized by demyelination of sensory nerves.
