Identification and expression of uridine diphosphate glycosyltransferase(UGT) gene family from Dendrobium officinale / 中国中药杂志

Uridine diphosphate glycosyltransferase(UGT) is a highly conserved protein in plants, which usually functions in secondary metabolic pathways. This study used the Hidden Markov Model(HMM) to screen out members of UGT gene family in the whole genome of Dendrobium officinale, and 44 UGT genes were identified. Bioinformatics was used to analyze the structure, phylogeny, and promoter region components of D. officinale genes. The results showed that UGT gene family could be divided into four subfamilies, and UGT gene structure was relatively conserved in each subfamily, with nine conserved domains. The upstream promoter region of UGT gene contained a variety of cis-acting elements related to plant hormones and environmental factors, indicating that UGT gene expression may be induced by plant hormones and external environmental factors. UGT gene expression in different tissues of D. officinale was compared, and UGT gene expression was found in all parts of D. officinale. It was speculated that UGT gene played an important role in many tissues of D. officinale. Through transcriptome analysis of D. officinale mycorrhizal symbiosis environment, low temperature stress, and phosphorus deficiency stress, this study found that only one gene was up-regulated in all three conditions. The results of this study can help understand the functions of UGT gene family in Orchidaceae plants and provide a basis for further study on the molecular regulation mechanism of polysaccharide metabolism pathway in D. officinale.

Case Report: Clinical characteristics and genetic analysis of two patients with hereditary hemorrhagic telangiectasia.

Objective: To analyze the clinical features and genetic characteristics of two patients with hereditary hemorrhagic telangiectasia (HHT) and to review the relevant literature. Methods: The clinical data of two HHT patients admitted to the author's hospital between April 2019 and February 2022 were retrospectively analyzed. Meanwhile, the genetic analysis was performed with their consent. Results: The first patient was a 62-year-old woman who had been complaining of shortness of breath and fever for 20 days. Her previous medical history included brain abscess drainage and video-assisted thoracoscopic surgery for a pulmonary hemangioma. A right heart catheterization revealed no pulmonary arterial hypertension, and an abdominal enhanced magnetic resonance imaging revealed multiple arteriovenous malformations in the liver. Her ACVRL1 heterozygous variants were discovered through whole-exon gene testing. The second case involved a 47-year-old woman who had been experiencing chest tightness for the past 2 years. Several years ago, she underwent brain abscess drainage and embolization of a pulmonary arteriovenous fistula. Ultrasound revealed generalized hepatic vascular dilation, and enhanced computed tomography revealed numerous pulmonary venous fistulas scattered in both lungs as well as multiple arteriovenous malformations in the liver. Her whole-exon gene testing revealed that she, like her son, had heterozygous ENG variants. Conclusion: HHT patients may experience infection, bleeding, dyspnea, and other symptoms. Imaging is important in disease diagnosis and management because early detection and treatment can prevent major complications and disability or even death.

Application of limiting antigen avidity enzyme immunoassay for estimating HIV-1 incidence in men who have sex with men / 中华流行病学杂志

Objective: To estimate the incidence of HIV-1 infection in men who have sex with men (MSM) in key areas of China through HIV-1 limiting antigen avidity enzyme immunoassay (LAg-Avidity EIA), analyze the deviation from the actual results and identify influencing factors, and provided reference for improving the accuracy of estimation results. Methods: Based on the principle of the cohort randomized study design, 20 cities were selected in China based on population size and the number of HIV-positive MSM. The sample size was estimated to be 700 according to the HIV-1 infection rate in MSM. MSM mobile phone app. was used to establish a detection appointment and questionnaire system, and the baseline cross-sectional survey was conducted from April to November 2019. LAg-Avidity EIA was used to identify the recent infected samples. The incidence of HIV-1 infection was calculated and then adjusted based on the estimation formula designed by WHO. The influencing factors were identified by analyzing the sample collection and detection processes. Results: Among the 10 650 blood samples from the participants, 799 were HIV-positive in initial screening, in which 198 samples (24.78%) missed during confirmation test. Only 621 samples were received by the laboratory. After excluding misreported samples, 520 samples were qualified for testing. A total of 155 samples were eventually determined as recent infection through LAg-Avidity EIA; Based on the estimation formula , the incidence of HIV-1 infection in MSM in 20 cities was 4.06% (95%CI:3.27%-4.85%), it increased to 5.53% (95%CI: 4.45%-6.60%)after the adjusting for sample missing rate. When the sample missing rate and misreporting rate were both adjusted, the incidence of HIV-1 infection in the MSM increased to 5.66% (95%CI:4.67%-6.65%). The actual incidence of HIV-1 infection in MSM in the 20 cities might be between 4.06% and 5.66%. Conclusions: Sample missing and misreporting might cause the deviation of the estimation of HIV-1 infection incidence. It is important to ensure the sample source and the quality of sample collection and detection to reduce the deviation in the estimation of HIV-1 infection incidence.

Clinical and molecular genetic study on 21 children with lissencephaly / 中华实用儿科临床杂志

Objective:To study the clinical features and molecular genetic mechanisms of children with lissencephaly (LIS), as well as to analyze the relationship between genotypes and phenotypes of the disease.Methods:From October 2016 to December 2017, the clinical data and follow-ups of 21 LIS children were collected in the Department of Neurology, Shenzhen Children′s Hospital.Whole genome sequencing (WGS) was performed for genetic testing.Results:Among these 21 cases, 18 cases developed epilepsy (86%), and 3 cases were seizure free (14%). The onset age of children with epilepsy was relatively young, and 16 cases occurred within 1 year old (89%). Among these cases, 16 were pachygyria (76%), 3 cases were agyria combined with pachygyria (14%) and 2 cases were agyria (10%). Epileptic syndromes included 12 cases of West syndrome (67%), 2 cases of Ohtahara syndrome (11%), 2 cases of other epileptic encephalopathy (11%), and 2 cases of focal epilepsy (11%). Brain magnetic resonance imaging(MRI) demonstrated that most cases were pachygyria, among which diffuse pachygyria was more common (56%, 9/16 cases). The results of WGS: 13 pathogenic or likely pathogenic single nucleotide variants (SNV) and copy number variants (CNV) were detected.The total detection rate was 62%, of which 2 cases were frameshift, 1 case was nonsense and 1 case was missense variants of PAFAH1B1, 6 cases were chromosome 17p13.3 deletion syndrome, thus lea-ding to the whole gene deletion of PAFAH1B1, and 1 case was missense variant of DCX, frameshift variant of KIF2A, and missense variant of PIK3R2, respectively.Totally, 48% (10/21 cases) of the cases were variants or deletions of PAFAH1B1, which resulted in lissencephaly in the parietal-occipital region of the brain.Novel variants were PAFAH1B1: c.1067G>A, PAFAH1B1: c.897delT and KIF2A: c.2225delG. Conclusions:Most cases of LIS accompanied with epilepsy, in which West syndrome was relatively more common.Brain MRI showed that most cases were diffuse pachygyria.The variants and deletions of PAFAH1B1 was the main genetic cause of LIS.The identification of the novel variants expanded the genotypical spectrum of LIS.

Prospective effects of protein and animal foods intake on age at menarche among Chinese girls / 中国学校卫生

Objective@#To investigate the prospective effects of the consumption of protein and animal foods before menarche on the age at menarche among Chinese girls.@*Methods@#This paper was based on the data collected in the China Health and Nutrition Survey(CHNS) from 1997 to 2015. A total of 683 girls aged 6 and over who had completed information on age at menarche, height, weight, per capita annual household income, maternal education level and participated in at least one complete dietary survey within 1 to 4 years before menarche were included.

The consumption of total protein, dairy, eggs, and aquatic products before menarche did not affect the age at menarche in Chinese girls.

DEPTOR improves cisplatin chemosensitivity in esophageal squamous cell carcinoma cells by inducing Caspase-1-mediated pyroptosis / 药学学报

Chemotherapy resistance is the main cause of poor prognosis in patients with advanced esophageal squamous cell carcinoma (ESCC). Pyroptosis is one of the anti-tumor mechanisms by chemotherapy drugs. Studies have shown that DEP-domain containing mTOR-interacting protein (DEPTOR) is correlated with sorafenib and gefitnib resistance, which is discovered as a naturally negative regulator of mammalian/mechanistic target of rapamicin (mTOR). In this study, DEPTOR knockdown (shDEPTOR) lentivirus was used to establish the stable DEPTOR knockdown ESCC cell lines. The results showed that knockdown of DEPTOR reduced chemosensitivity to cisplatin in ESCC cells in vitro. The lower expression of DEPTOR caused less extensive morphological characteristics of pyroptosis than that was observed in sh-con cells with the treatment of cisplain. Further studies showed that knockdown of DEPTOR induced downregulation of Caspase-1 expression and reduction of Caspase-1 activation, thereby inhibiting the activation of the classical pathway of pyroptosis. This paper demonstrates that DEPTOR can improve cisplatin chemosensitivity in ESCC cells via inducing Caspase-1-mediated pyroptosis.

Morphology of reproductive accessory glands in female Sepia pharaonis (Cephalopoda: Sepiidae) sheds light on egg encapsulation.

The pharaoh cuttlefish, Sepia pharaonis, is an important cephalopod fishery species in southeastern Asia, with understudied reproductive physiology. The present study aimed to investigate the cellular characteristics of epithelial cells found in the nidamental glands (NGs) and accessory NGs (ANGs), as well as the structural connections between these two glands in mature female S. pharaonis. A histological analysis revealed two types of epithelial cells in NGs: Alcian blue-positive, PAS-negative mucosubstance-secreting cells and eosinophilic, PAS-positive granule-secreting cells. Using transmission electron microscopy, three types of epithelial cells were identified: cells with electron-dense granules, cells with electron-lucent granules, and cells with both cilia and microvilli in the apex. Mature ANGs contain an abundance of tubular units composed of epithelial cells resting on a thin layer of basal lamina. Innervated muscle cells are tightly adhered to the basal lamina. In addition, we observed epithelial canalization of ANG tubules penetrating through the connective tissue linking NGs and the walls of the tubules in ANGs, which allows the contents of the ANG tubules to be transported to the NGs. Our results suggest that ANGs participate in the encapsulation of the ova via the same pathway as NGs, which provides an important basis for future studies on the mechanism of protection provided by NGs and ANGs during embryonic development in S. pharaonis.

OBJECTIVES@#To observe the preventive and therapeutic action of Yuyin Ruangan Granule (YRG, Traditional Chinese Medicine) in hepatic fibrosis rats model and its effect on transforming growth factor-β1 (TGF-β1) expression.@*METHODS@#The Wistar rats were randomly divided into 6 group (=10), and the model of hepatic fibrosis rats was established by subcutaneous injected with carbon tetrachloride (CCL4), fed on high-fat diet and 20% ethanol for 6 weeks, to survey the effect and mechanism of YRG preventing hypatic fibrosis by detecting liver function (the activity of alanine aminotransferase(ALT), aspartate aminotransferase(AST), etc.) of liver fibrosis rats, liver fibrosis indicators (hyaluronic acid, Ⅲ procollagen, type IV collagen, laminin and hepatic pathology, etc.), and TGF-β1 expression in liver tissue after 6 weeks treated with YRG through intragastric administration (q. d.).@*RESULTS@#At the 7 week, fibrotic lesions appears distinctly in liver tissue of model group compared with control group (<0.01), YRG of 6.2~28.8 g/kg could significantly decrease hepatic index, ALT and AST activities, content of hyaluronic acid(HA), Ⅲ procollagen (PCⅢ), type Ⅳ collagen(C-Ⅳ), laminin (LN) in serum, relieve liver fibrosis pathological changes and inhibit TGF-β1 expression in fibrotic liver tissue (<0.05, <0.01).@*CONCLUSIONS@#YRG has significantly preventive effects on liver fibrosis rats model, and it may be one of its mechanisms to inhibit expression of TGF-β1.

Effects of combined administration of Radix Angelicae Sinensis and hydrocortisone on the therapeutic action in the murine asthma model / 中国应用生理学杂志

OBJECTIVE@#To investigate the effects of Radix Angelicae Sinensis (RASI) and hydrocortisone combination on the murine asthma model and the mechanism.@*METHODS@#BALB/c mice were randomly divided into control group, blood stasis model group, asthma model group, HSS group, RASI group and RASI+HSS group (=12). Ovalbumin (OVA) was used to replicate mice asthma model and hydrocortisone sodium succinate (HSS) to copy blood stasis model. Effects of RASI, HSS and their combination on hemorheology, anti-asthma (asthmatic behaviors, lung function, lung index and water content in lung tissue) were observed. and anti-asthma mechanisms The expression of relative cytokines, high-mobility group box 1 (HMGB1), toll-like receptor 4 (TLR4) and nuclear factor-κB (NF-κB) was detected by ELISA and immunohistochemistry respectively.@*RESULTS@#Eight g/kg RASI, 0.05 g/kg HSS and their combination could significantly relieve asthma behavioral indicators, improve lung function, reduce lung index and water content in lung tissue, decrease the levels of TNF-α, IL-1β and IL-6 in broncho-alveolar lavage fluid (BALF), and inhibit the high expression of HMGB1, TLR4 and NF-κB in lung tissue. The improvement of lung function and the decrease in level of relative cytokines (TNF-α、IL-1βIL-6) were better in RASI+HSS group than those in RASI group and HSS group, and the inhibition of protein expression of TLR4 and NF-κB was also too. Combined administration of RASI and hydrocortisone could decrease serum thromboxane B2 (TXB2) content and blood viscosity, which were increased induced by hydrocortisone.@*CONCLUSIONS@#Combined administration of RASI and hydrocortisone have obvious anti-asthma effects and one of the mechanisms is to inhibit protein synthetization of HMGB1, TLR4 and NF-κB.The combined administration of RASI and hydrocortisone has stronger improvement of lung function than that of RASI and hydrocortisone alone, and it may be related to the inhibition of TLR4 and NF-κB synthetization. The combined administration of RASI can alleviate abnormal changes of hemorheology induced by hydrocortisone in treatment of asthma.
