Objective: To investigate the diagnosis and surgical treatment of sinonasal phosphaturic mesenchymal tumor (PMT). Methods: The medical records of nine patients who had been diagnosed as sinonasal PMT in Department of Otorhinolaryngology Head and Neck Surgery, Shanghai JiaoTong University Affiliated Sixth People's Hospital between January 2015 and May 2020 were collected, including 4 males and 5 females, ranging from 36 to 59 years. The patient's previous history, clinical manifestations, imaging findings, laboratory results, surgical procedure, pathological results and postoperative follow-up data were analyzed by descriptive statistical analysis. Results: All patients presented hypophosphatemia and tumor-induced osteomalacia (TIO) with a disease course of 1 to 19 years. The imaging examination and intraoperative findings identified two cases with peripheral tissue infiltration, two cases with contralateral nasal cavity invasion, and one case with intracranial invasion. Five patients underwent unilateral endoscopic resection while two patients underwent bilateral endoscopic resection, and the remaining two patients underwent unilateral transorbital ethmoid artery ligation plus endoscopic tumor resection and endoscopic combined with transfrontal tumor resection (n=1 each). Expect for one case developed recurrence and intracranial involvement, the other patients achieved clinical remission and no recurrence was observed during the six-month follow-up. Conclusions: The diagnosis of sinonasal PMT needs combination of clinical manifestation, imaging, and pathological findings. Complete surgical excision and long-term postoperative follow-up are imperative.

Transcriptome analysis of genes related to gonad differentiation and development in Muscovy ducks.

BACKGROUND: Sex-related genes play a crucial role in gonadal differentiation into testes or ovaries. However, the genetic control of gonadal differentiation in Muscovy ducks remains unknown. Therefore, the objective of our study was to screen new candidate genes associated with ovarian and testicular development. RESULTS: In this study, 24 males before gonadal differentiation (MB), 24 females before gonadal differentiation (FB), 24 males after gonadal differentiation (MA) and 24 females after gonadal differentiation (FA) were selected from Putian Muscovy ducks, forming 4 groups. RNA-Seq revealed 101.76 Gb of clean reads and 2800 differentially expressed genes (DEGs), including 46 in MB vs FB, 609 in MA vs FA, 1027 in FA vs FB, and 1118 in MA vs MB. A total of 146 signalling pathways were enriched by KEGG analysis, among which 20, 108, 108 and 116 signalling pathways were obtained in MB vs FB, MA vs MB, MA vs FA and FA vs FB, respectively. In further GO and KEGG analyses, a total of 21 candidate genes related to gonad differentiation and development in Muscovy ducks were screened. Among these, 9 genes were involved in the differentiation and development of the testes, and 12 genes were involved in the differentiation and development of the ovaries. In addition, RNA-Seq data revealed 2744 novel genes. CONCLUSIONS: RNA-Seq data revealed 21 genes related to gonadal differentiation and development in Muscovy ducks. We further identified 12 genes, namely, WNT5B, HTRA3, RSPO3, BMP3, HNRNPK, NIPBL, CREB3L4, DKK3, UBE2R2, UBPL3KCMF1, ANXA2, and OSR1, involved in the differentiation and development of ovaries. Moreover, 9 genes, namely, TTN, ATP5A1, DMRT1, DMRT3, AMH, MAP3K1, PIK3R1, AGT and ADAMTSL1, were related to the differentiation and development of testes. Moreover, after gonadal differentiation, DMRT3, AMH, PIK3R1, ADAMTSL1, AGT and TTN were specifically highly expressed in males. WNT5B, ANXA2 and OSR1 were specifically highly expressed in females. These results provide valuable information for studies on the sex control of Muscovy ducks and reveal novel candidate genes for the differentiation and development of testes and ovaries.

The clinical value of neutrophil to lymphocyte ratio in postmenopausal patients with type 2 diabetes / 天津医药

Objective To investigate the clinical value of neutrophil-lymphocyte ratio (NLR) in postmenopausal patients with type 2 diabetes mellitus (T2DM). Methods A total of 128 newly diagnosed T2DM female patients were randomly recruited from the Zhujiang Hospital of Southern Medical University from March to September 2015. According to the physiological state, the patients were divided into menopausal group (n=66) and non-menopausal group (n=62). Fifty-six healthy females were chosen as the control group. The values of blood pressure, blood lipid, fasting plasma glucose (FPG), fasting insulin (FINS) and white blood count (WBC), neutrophil count, percentage of neutrophils,lymphocytes count, and percentage of lymphocytes were detected and compared between three groups. The NLR and the HOMA insulin resistance index (HOMA-IR) were calculated. Results Age, systolic blood pressure (SBP), triglyceride (TG), FINS, percentage of neutrophil, NLR, HOMA-IR were significantly higher in menopause group than those of control group and non-menopause group (P0.05). There was no linear correlation between NLR and HOMA-IR (rs=0.015, P > 0.05), HbA1c (r=0.030, P > 0.05). Conclusion NLR is of a certain significance in the assessment of inflammatory status and IR levels in postmenopausal women with T2DM, which may be related to the changes of autonomic nervous system.

Progress in genetics of autoimmune hepatitis / 上海交通大学学报（医学版）

Autoimmune hepatitis (AIH) is an autoimmune liver disorder characterized by chronic inflammation of liver. Although the etiology of AIH remains obscure, genetic and environmental factors may contribute to the development of AIH. In the past years, investigators have attempted to uncover the genetic architecture of AIH. Multiple genetic loci have been reported to be associated with AIH, in which human leukocyte antigen (HLA) alleles were strongly associated with disease onset and clinical manifestations for decades. A recent genome wide association study identified that two loci (SH2B3 and CARD10) increased susceptibility of AIH, in addition to the HLA loci. The genetic study is aiming to help to elucidate the genetic pathogenesis for AIH.

The relationship between hyperuricemia with neutrophil-to-lymphocyte ratio and insulin resistance in type ;2 diabetes mellitus / 实用医学杂志

Objective To research the relationship between Serum uric acid (SUA) levels and the Neu-trophil-to-lymphocyte Ratio (NLR) of Type 2 Diabetes Mellitus (T2DM) patients. Method 273 newly diag-nosed T2DM patients are selected in accordance with the WHO diagnostic criteria: Male subjects with SUA lev-els ≥ 416 μmol/L(70 mg/L), and female subjects with SUA levels ≥ 357 μmol/L (60 mg/L) are sorted into the high SUA (HUA) group (224 subjects), and the rest into the normal SUA (NUA) group (49 subjects). 100 subjects were selected as a control group. One-Way analysis of variance was applied to the data of the three groups; Pearson correlation analysis was used to calculate the correlation of SUA levels , NLR and IR; risk fac-tors influencing SUA levels were analyzed with Logistic regression analysis; ROC curve analysis was used to de-termine the diagnostic value of NLR to HUA, and the optimal threshold value of NLR. Result (1) The NLR and IR of the HUA group was significantly higher than those of the NUA group (2.54 ± 0.63 vs. 2.05 ± 0.61, P < 0.001; 3.70 ± 1.86 vs. 2.71 ± 1.43, P < 0.001); (2) In the HUA group, UA was positively correlated with NLR and IR (respectively r = 0.480, P < 0.001; r = 0.332, P < 0.001). (3)NLR (P < 0.001, EXP(B)= 8.045, 95%CI = 4.597 ~ 14.079) was a risk factor of Hyperuricemia. Conclusion Our results suggest that NLR may be an independent risk factor of Hyperuricemia.

Protective effects of extracts from Pomegranate peels and seeds on liver fibrosis induced by carbon tetrachloride in rats.

BACKGROUND: Liver fibrosis is a feature in the majority of chronic liver diseases and oxidative stress is considered to be its main pathogenic mechanism. Antioxidants including vitamin E, are effective in preventing liver fibrogenesis. Several plant-drived antioxidants, such as silymarin, baicalin, beicalein, quercetin, apigenin, were shown to interfere with liver fibrogenesis. The antioxidans above are polyphenols, flavonoids or structurally related compounds which are the main chemical components of Pomegranate peels and seeds, and the antioxidant activity of Pomegranate peels and seeds have been verified. Here we investigated whether the extracts of pomegranate peels (EPP) and seeds (EPS) have preventive efficacy on liver fibrosis induced by carbon tetrachloride (CCl4) in rats and explored its possible mechanisms. METHODS: The animal model was established by injection with 50 % CCl4 subcutaneously in male wistar rats twice a week for four weeks. Meanwhile, EPP and EPS were administered orally every day for 4 weeks, respectively. The protective effects of EPP and EPS on biochemical metabolic parameters, liver function, oxidative markers, activities of antioxidant enzymes and liver fibrosis were determined in CCl4-induced liver toxicity in rats. RESULTS: Compared with the sham group, the liver function was worse in CCl4 group, manifested as increased levels of serum alanine aminotransferase, aspartate aminotransferase and total bilirubin. EPP and EPS treatment significantly ameliorated these effects of CCl4. EPP and EPS attenuated CCl4-induced increase in the levels of TGF-ß1, hydroxyproline, hyaluronic acid laminin and procollagen type III. They also restored the decreased superoxide dismutase (SOD), glutathione peroxidase (GSH-Px) activities and inhibited the formation of lipid peroxidized products in rats treated with CCl4. CONCLUSION: The EPP and EPS have protective effects against liver fibrosis induced by CCl4, and its mechanisms might be associated with their antioxidant activity, the ability of decreasing the level of TGF-ß1 and inhibition of collagen synthesis.

Advances in research on oncolytic adenoviruses in tumor therapy / 病毒学报

Oncolytic adenoviruses (Ads), which are live, replication-competent viruses that can selectively replicate in tumor cells and lead to cell lysis, have been used in tumor therapy. But due to the complexity and high mutability of human tumors, it becomes a major strategy to improve the selectivity, efficacy, and safety of oncolytic Ads. The oncolytic Ads that can express short hairpin RNA, cytokines, suicide gene, and matrix-modulating proteins have higher antitumor activity than the wild type. Tumor-specific promoters, especially hTERT and HRE promoters, increase the selectivity of oncolytic Ads for tumor cells. Moreover, oncolytic Ads surface-modified by polyethylene glycol (PEG), liposomes, biodegradable nanoparticles, and polypeptides have reduced immunogenicity and hepatotoxicity and improved antitumor activity when systemically administered, and the selectivity of oncolytic Ads can be significantly increased when linking PEG to antibodies, small peptides, cytokines, and ligands. Therefore, engineered oncolytic Ads combining the advantages of viral and non-viral vectors, as well as immunotherapy, are a promising strategy for improving the efficacy of targeted virotherapy.

Differentiation of rat bone marrow mesenchymal stem cells into adipocytes and blockage of the differentiation / 中华肿瘤杂志

<p><b>OBJECTIVE</b>To explore the pathogenesis of tumors by blocking the normal differentiation process of stem cells.</p><p><b>METHODS</b>Bone marrow mesenchymal stem cells (BMSCs) from rats were isolated, cultured and purified by whole bone marrow adherence method. The rat BMSCs were induced to differentiate into adipocytes with dexamethasone, insulin and indomethacin. Blockage of the differentiation process was induced by 3-methylcholanthrene (3-MC).</p><p><b>RESULTS</b>The differentiation experiment showed that at 30 days after the induction, oil red O staining-positive cells occurred with increased intracytolasmic lipid droplets, characteristic for adipocytes. The differentiation blockage experiment showed that at 30 days after induction, the deposits of oil red O staining-cytoplasmic lipid droplets was significantly reduced, indicating that the blocked cells were adipocytes, but not fully differentiated. Morphological identification showed that cell contact inhibition disappeared, abnormal cell nuclei, increased number of micronucleus aberration and karyotype abnormalities, indicating that malignant transformation of the stem cells occurred after the differentiation blockage.</p><p><b>CONCLUSIONS</b>The results of this study show a blockage of the differentiation of that stem cells at the intermediate phase, and a tendency of malignant transformation of the stem cells. The results of our study provide new evidence that cancer stem cells may be originated by suppression of stem cell differentiation.</p>

Haplotype-based case-control study of the human AGTR1 gene and essential hypertension in Han Chinese subjects.

OBJECTIVES: Essential hypertension is considered to be a multifactorial trait resulting from the combined influence of environmental and genetic determinants. The aim of the study is to assess the association between the human AGTR1 gene and essential hypertension (EH) using a haplotype-based case-control study in Han Chinese subjects. DESIGN AND METHODS: Seven tag SNPs and the A1166C polymorphism of the AGTR1 gene were genotyped in 510 hypertension subjects and 510 normotensive subjects using PCR-RFLP method. RESULTS: Single SNP analyses indicated that the rs12695895 was significantly associated with hypertension, adjusted for covariates. Compared with the other haplotypes, Hap4 (AGGACTT) which carry the susceptible rs12695895 A allele was found to significantly increase the risk of EH with odds ratios equal to 1.84 (p=0.0002). CONCLUSIONS: The present results indicate that rs12695895 might be a genetic marker for EH and Hap4 (AGGACTT) was associated with hypertension in Han Chinese population.

Effects of des-aspartate-angiotensin I on neointima growth and cardiovascular hypertrophy.

The in vitro anti-hypertrophic and hyperplastic actions of des-aspartate-angiotensin I (DAA-I) on cultured cardiovascular cells have been demonstrated in earlier experiments. The present study investigated its effects on the development of neointima in balloon catheter-injured carotid artery of the Sprague-Dawley (SD) rat and the development of cardiovascular hypertrophy in the spontaneously hypertensive rat. Treatment with i.v. DAA-I for 14 days post-injury dose-dependently attenuated the development of neointima. The maximum effect was obtained at 34 pmol/kg/day. The data support the possibility that endogenous angiotensins could inhibit neointima growth. This opens up avenues for their therapeutic elevation in combating neointima-related restenosis of which current drugs are not fully effective in suppressing. Five-week-old pre-hypertensive SHR, when orally administered with a dose of 769 nmol/kg/day DAA-I for a duration of 47 weeks, showed significant reduction in the development of cardiac and vascular hypertrophy compared to the untreated controls. Similar treatment with DAA-I had no effect on the Wistar Kyoto rats. The present findings support the contention that, besides angiotensin II, other endogenous angiotensins are also involved in the regulation and/or pathophysiology of the cardiovascular system.

Comparison of characteristics between indocyanine green and fundus fluorescence angiography in patients with age-related macular degeneration / 中华老年医学杂志

Objective To compare the characteristics between indocyanine green angiography (ICGA) and fundus fluorescence angiography ( FFA ) in patients with age-related macular degeneration ( ARMD ). Methods Twenty-five cases ( 35 eyes ) were diagnosed as exudative ARMD by ocular examination. Their age ranged from 60 to 81 years. The visual acuities were 1.0 at FC/30 cm before eye. We analyzed and compared the characteristics of FFA and ICGA in these patients. Results 5 eyes ( 14.3% ) with classic choroidal neovascularization ( CNV ) were found by FFA examination. 15 eyes ( 42.9% ) with classic CNV were found by ICGA examination. Of 20 eyes with occult CNV considered by FFA, 7 eyes had classic CNV by ICGA. Of 3 eyes considered as serous retinal pigment epithelial detachment ( PED ) without classic CNV by FFA, 1 eye had serous PED with classic CNV and 2 eyes had classic CNV by ICGA.1 eye was diagnosed as serous PED with CNV by FFA, and as occult CNV by ICGA. Conclusions ICGA raise detectability and accuracy of CNV in ARMD compared with FFA. It is contributive to early treatment in ARMD.
