MiR -18a -5p aggravates homocysteine -induced myocardial injury via autophagy / 中南大学学报(医学版)

OBJECTIVES@#Hyperhomocysteinaemia (Hcy) is an independent risk factor for cardiovascular and cerebrovascular diseases. MicroRNA (miR)-18a-5p is closely related to cardiovascular diseases. This study aims to investigate the effects of miR-18a-5p on homocysteine (Hcy)-induced myocardial cells injury.@*METHODS@#H9c2 cells were transfected with miR-18a-5p mimic/miR-18a-5p mimic negative control (NC) or combined with Hcy for intervention, and untreated cells were set as a control group. The transfection efficiency was verified by real-time RT-PCR, and cell counting kit-8 (CCK-8) assay was used to determine cell viability. Flow cytometry was used to detect apoptosis and reactive oxygen species (ROS) levels. Western blotting was performed to measure the protein levels of microtubule-associated protein 1 light chain 3 (LC3)-I, LC3-II, Beclin1, p62, Bax, Bcl-2, and Notch2. Dual luciferase reporter assay was used to detect the interaction of miR-18a-5p with Notch2.@*RESULTS@#Compared with the control, treatment with Hcy or transfection with miR-18a-5p mimic alone, or combined treatment with Hcy and miR-18a-5p mimic/miR-18a-5p mimic NC significantly reduced the H9c2 cell viability, promoted apoptosis and ROS production, up-regulated the expressions of Bax and Beclin, down-regulated the expressions of Bcl-2, p62, and Notch2, and increased the ratio of LC3-II/LC3-I (all P<0.05). Compared with the combined intervention of miR-18a-5p mimic NC and Hcy group, the above indexes were more significantly changed in the combined intervention of miR-18a-5p mimic and Hcy group, and the difference between the 2 groups was statistically significant (all P<0.05). There is a targeted binding between Notch2 and miR-18a-5p.@*CONCLUSIONS@#MiR-18a-5p could induce autophagy and apoptosis via increasing ROS production in cardiomyocytes, and aggravate Hcy-induced myocardial injury. Notch2 is a target of miR-18a-5p.

Pathological significance of plasma cell infiltration in diagnosing lymph node diseases / 中华病理学杂志

Objective: To investigate the value of plasma cells for diagnosing lymph node diseases. Methods: Common lymphadenopathy (except plasma cell neoplasms) diagnosed from September 2012 to August 2022 were selected from the pathological records of Changhai Hospital, Shanghai, China. Morphological and immunohistochemical features were analyzed to examine the infiltration pattern, clonality, and IgG and IgG4 expression of plasma cells in these lymphadenopathies, and to summarize the differential diagnoses of plasma cell infiltration in common lymphadenopathies. Results: A total of 236 cases of lymphadenopathies with various degrees of plasma cell infiltration were included in the study. There were 58 cases of Castleman's disease, 55 cases of IgG4-related lymphadenopathy, 14 cases of syphilitic lymphadenitis, 2 cases of rheumatoid lymphadenitis, 18 cases of Rosai-Dorfman disease, 23 cases of Kimura's disease, 13 cases of dermal lymphadenitis and 53 cases of angioimmunoblastic T-cell lymphoma (AITL). The main features of these lymphadenopathies were lymph node enlargement with various degrees of plasm cell infiltration. A panel of immunohistochemical antibodies were used to examine the distribution of plasma cells and the expression of IgG and IgG4. The presence of lymph node architecture could help determine benign and malignant lesions. The preliminary classification of these lymphadenopathies was based on the infiltration features of plasma cells. The evaluation of IgG and IgG4 as a routine means could exclude the lymph nodes involvement of IgG4-related dieases (IgG4-RD), and whether it was accompanied by autoimmune diseases or multiple-organ diseases, which were of critical evidence for the differential diagnosis. For common lesions of lymphadenopathies, such as Castleman's disease, Kimura's disease, Rosai-Dorfman's disease and dermal lymphadenitis, the expression ratio of IgG4/IgG (>40%) as detected using immunhistochemistry and serum IgG4 levels should be considered as a standard for the possibility of IgG4-RD. The differential diagnosis of multicentric Castleman's diseases and IgG4-RD should be also considered. Conclusions: Infiltration of plasma cells and IgG4-positive plasma cells may be detected in some types of lymphadenopathies and lymphomas in clinicopathological daily practice, but not all of them are related to IgG4-RD. It should be emphasized that the characteristics of plasma cell infiltration and the ratio of IgG4/IgG (>40%) should be considered for further differential diagnosis and avoiding misclassification of lymphadenopathies.

Pathological features related to onco-immunity and their clinical significance of pancreatic ductal adenocarcinoma / 中华病理学杂志

Objective: To investigate the tumor immunity-related pathologic features and clinical significance in pancreatic ductal adenocarcinoma (PDAC). Methods: All pathologic materials and clinical information of 192 PDAC patients from the Cancer Hospital of the University of Chinese Academy of Sciences from January 2010 to December 2020 were collected. The onco-immune microenvironment associated morphologic features were evaluated, and MHC-Ⅰ, PD-L1, CD3, and CD8 expression were detected by immunohistochemistry (IHC). Then the correlation between the factors and their influence on prognosis was analyzed. Results: There were 163 cases of non-specific adenocarcinoma (163/192, 84.90%), 18 cases of adeno-squamous carcinoma (18/192, 9.37%), and 11 cases of other rare subtypes (11/192, 5.73%). Perineural invasion was observed in 110 cases (110/192, 57.29%) and vascular invasion in 86 cases (86/192, 44.79%). There were 84 cases (84/182, 46.15%) with severe chronic inflammation. Tumor infiltrating immune cell numbers (TII-N) were increased in 52 cases (52/192, 27.08%). Lymphocytes and plasma cells were the main infiltrating immune cells in 60 cases (60/192, 31.25%), whereas in 34 cases (34/192, 17.71%) the tumors were mainly infiltrated by granulocytes, and 98 cases (98/192, 51.04%) showed mixed infiltration. CD3+T cells were deficient in 124 cases (124/192, 66.31%). CD8+T cells were deficient in 152 cases (152/192, 79.58%). MHC-Ⅰ expression was down-regulated in 156 cases (156/192, 81.25%), and PD-L1 was positive (CPS≥1) in 46 cases (46/192, 23.96%). Statistical analysis showed that TII-N was negatively correlated with vascular invasion (P=0.035), perineural invasion (P=0.002), stage (P=0.004) and long-term alcohol consumption (P=0.039). The type of immune cells correlated positively with chronic pancreatic inflammation (P=0.002), and negatively with tumor differentiation (P=0.024). CD8+T cells were positively correlated with CD3+T cells (P=0.032), MHC-Ⅰ expression (P<0.001) and PD-L1 expression (P=0.001), and negatively correlated with long-term smoking (P=0.016). Univariate analysis showed that histological nonspecific type (P=0.013) and TII-N (P<0.001) were the factors for good prognosis. Vascular invasion (P=0.032), perineural invasion (P=0.001), high stage (P=0.003) and long-term alcohol consumption (P=0.004) were adverse prognostic factors. COX multivariate risk analysis found that TII-N was an independent favorable factor for PDAC, while perineural invasion was an independent adverse risk factor. Conclusions: TII-N is an independent superior prognostic factor for PDAC, and significantly correlated with many factors; chronic alcohol consumption and smoking may inhibit onco-immunity in PDAC patients.

Fecal Fungal Community Structure of Newly Diagnosed Patients With Crohn's Disease in Suzhou, Jiangsu Province / 胃肠病学

Background: The pathogenic mechanism of Crohn's disease (CD) is currently unclear. Previous studies have shown that intestinal microorganism plays an important role in the pathogenesis of CD. Aims: To study the fecal fungal community structure of CD patients in Suzhou, Jiangsu Province and to analyze the relationship between alterations in fugal community structure and disease status. Methods: The feces of 23 newly diagnosed CD patients and 18 healthy subjects in Suzhou, Jiangsu Province were collected. Fecal genomic DNA was extracted, and the ITS1 fragments were amplified by PCR for clone library construction. After sequencing on HiSeq platform, the species diversity of fecal samples and the species differences between different groups were analyzed based on OTUs. Furthermore, the correlations between the fungi with up-regulated abundance and inflammatory indicators (CRP, ESR, and fecal calprotectin) and CD activity index (CDAI) were analyzed. Results: The fungal species diversity in fecal samples was significantly reduced in CD patients compared with healthy subjects. From the levels of phylum, class, order, family, genus, and species, the fungi with up-regulated abundance in fecal samples of CD patients were Saccharomycetes, Saccharomycetales, Incertae_sedis, Candida and Candida albicans; the fungi newly emerged were Trichosporonales and Trichosporonaceae; Wallemiomycetes was down-regulated in abundance and Glomeromycota, Glomeromycetes, Glomeraceae, Lodderomyces, Candida intermedia, and Candida sp were absent. The abundance of Candida albicans in feces was positively correlated with the fecal calprotectin in CD patients (r=0.557, P=0.031). Conclusions: Compared with healthy subjects, the structure of intestinal fungal community in CD patients changed significantly. The species diversity was reduced and the abundance of opportunistic pathogenic fungi such as Candida albicans was increased and might be involved in the disease progression.

Bioassay-guided isolation of saikosaponins with agonistic activity on 5-hydroxytryptamine 2C receptor from Bupleurum chinense and their potential use for the treatment of obesity / 中国天然药物

5-Hydroxytryptamine 2C (5-HT) receptor is one of the major targets of anti-obesity agents, due to its role in regulation of appetite. In the present study, the 70% EtOH extract of the roots of Bupleurum chinense was revealed to have agonistic activity on 5-HT receptor, and the subsequent bioassay-guided isolation led to identification of several saikosaponins as the active constituents with 5-HT receptor agonistic activity in vitro and anti-obesity activity in vivo. The new compound, 22-oxosaikosaponin d (1), was determined by extensive spectroscopic analyses (HR-ESI-MS, IR, and 1D and 2D NMR). The primary structure-activity relationship study suggested that the intramolecular ether bond between C-13 and C-28 and the number of sugars at C-3 position were closely related to the 5-HT receptor agonistic activity. Saikosaponin a (3), the main saponin in B. chinense, showed obviously agonistic activity on 5-HT receptor with an EC value of 21.08 ± 0.33 μmol·Lin vitro and could reduce food intake by 39.1% and 69.2%, and weight gain by 13.6% and 16.4%, respectively, at 3.0 and 6.0 mg·kgin vivo. This investigation provided valuable information for the potential use of B. chinense as anti-obesity agent.

Study on feeding support and the cause of stopping oral feeding in premature infants / 中国实用护理杂志

Objective To investigate the use of feeding support and influencing factors of oral feeding among premature infants. Methods Totally 103 premature infants with oral feeding problems hospitalized during June to December 2014 were enrolled. The postmenstrual age and feeding support were observed at the time of initiation oral feeding and full oral feeding. Moreover, the progress and performance of oral feeding, the daily increase in weight, the time of body weight regain, the time of assisted ventilation and length of hospital stay and so on were calculated. Results There were 96 premature infants using feeding support at the time of initiation oral feeding and 58 premature infants at the time of full oral feeding. Logistic regression analysis showed that birth gestational age(OR=2.195, P<0.01), birth weight(OR=1.003, P<0.01), severity of illness(OR=0.121, P<0.01) and feeding tolerance(OR=0.007, P<0.01)were important factors of oral feeding among premature infants. Conclusions The premature infants with small gestational age at birth, low birth weight, severity of illness, and feeding intolerance are high risk populations of oral feeding.

AIM@#The aim of this work was to establish a specific and sensitive method to comprehensively investigate and compare chemical constituents of Fuzi-Gancao herb pair (FG), consisting of Aconitum carmichaelii Debeaux (Fuzi, Chinese) and Roast Radix Glycyrrhizae (Glycyrrhiza glabra L., Gancao, in Chinese) and Fuzi alone to explore the underlying interaction mechanism of FG.@*METHOD@#An ultra-fast liquid chromatography-ion trap/time-of-flight mass spectrometry (UFLC/MS-IT-TOF) method using diazepam as internal standard was developed for the identification and semi-quantitative analysis of the phytochemical constituents of Fuzi and FG. Chromatographic separation was achieved on a UFLC column using a gradient program with 40 mmol·L(-1) ammonium acetate and acetonitrile as the mobile phase.@*RESULTS@#Fifty-one of the sixty compounds, including forty-five C19-diterpenoid alkaloids and six C20-diterpenoid alkaloids were tentatively identified in the extracts of Fuzi and FG through accurate mass measurements and fragmentation patterns. Comparing the contents of these alkaloids in these two extracts, it was found that the diester-diterpenoid alkaloids (DDAs) and the alkylolamine-diterpenoid alkaloids (ADAs) were increased, while the monoester-diterpenoid alkaloids (MDAs) were decreased in the extracts of FG.@*CONCLUSION@#This work provided comprehensive information for the quality control of Fuzi preparations, and the further investigation on the compatibility mechanisms of FG.

Effect of Tonifying Kidney with Traditional Chinese Medicine on Serum Leptin Levels in Patients with Polycystic Ovarian Syndrome / 中国生化药物杂志

Objective To explore the effect of tonifying kidney with traditional Chinese medicine together with estradiol valerate and clomiphene citrate on serum leptin levels in patients with polycystic ovarian syndrome. Method Two hundred and eight patients with PCOS were randomly divided into observation group (n=104) and control group (n=104). Patients in control group and observation group took estradiol valerate and clomiphene citrate, while patients in observation group took Shiying Minlin soup for three months. Crinosity, body temperature, acne&Skin diseases, and menoxenia were recorded; Leptin (LP) and five hormone including follicle stimulating hormone (FSH),luteinizing hormone (LH), prolactin (PRL), estradiol (E 2) and testosterone (T) are determined using euzymelinked immunosorbent assay. Results Crinosity, body temperature, acne&Skin diseases, and menoxenia were improved;the level of FSH, LH, PRL, E 2, T in both observation and control group decreased and the content in observation group are high than that in control group, while LH,T and E 2 are lower. Conclusion Treatment with tonifying kidney with traditional Chinese medicine on polycystic ovarian syndrome can decrease the level of FSH, LH, PRL, E 2, T and LP. Compared with western medicine, tonifying kidney with traditional Chinese medicine showed advantage in the terms of treatment on polycystic ovarian syndrome.

Clinicopathological features and prognostic factors of 216 cases with primary gastrointestinal tract non-Hodgkin's lymphoma / 中华血液学杂志

<p><b>OBJECTIVE</b>To investigate the clinicopathological features of primary gastrointestinal non-Hodgkin's lymphomas (PGI-NHL) and their prognostic values.</p><p><b>METHODS</b>The clinical and pathological data of 216 patients diagnosed as PGI-NHL from Zhejiang Cancer Hospital were analyzed retrospectively. χ² test, log-liner model analysis, COX proportional hazard regression analysis and Life-table survival analysis were used to analyze the survival status of the patients by SAS 8.2 software, and Log-rank test was performed to couple the overall survival rates with different prognostic factors.</p><p><b>RESULTS</b>Totally, the age of onset was 8 to 89 years with the median age of 56.5 years. Male versus female was 1.27∶1(121∶95). The most frequently involved location was stomach (147 cases, 68.1%), followed by ileocecus (25 cases, 11.6%), large intestine (20 cases, 9.3%), small intestine (17 cases, 7.9%) and multiple GI involvement (5 cases, 2.3%). 182 cases were classified as B cell lymphomas, 22 cases as T cell lymphomas, and 12 cases not classified exactly due to insufficient data. The 3-year and 5-year survival rates of the patients were 69.4% and 53.3%, respectively. Univariate analysis revealed that age＞60 years, ECOG≥2, high LDH level, stage Ⅲ-Ⅳ, IPI≥2, T cell type and intestinal involvement were predictors for poor prognosis. IPI≥2, T cell type and intestinal involvement were independent adverse predictors for prognosis by multiple COX proportional hazard regression analysis. Among different treatment groups, cases received chemotherapy combined with local radiotherapy gained the best survival status.</p><p><b>CONCLUSION</b>B-cell lymphoma was the main pathological type in PGI-NHL; IPI≥2, T-cell type and intestinal involvement are independent adverse predictors for prognosis; chemotherapy combined with local radiotherapy might be the choice of approach for advanced stage and aggressive PGI-HNL.</p>
