Impact of interaction between NLRP3, TLR4 gene polymorphisms and triglyceride-glucose index on gout / 中华内分泌代谢杂志

Objective:To explore the effect of triglyceride glucose(TyG) index, single nucleotide polymorphism of Toll-like receptor 4(TLR4) and NOD-like receptor thermal protein domain associated protein 3(NLRP3) genes, and its interaction on the risk of gout.Methods:A total of 315 male patients with gout and 499 men for health checkup at the same period were selected. General data were collected through questionnaires, and peripheral venous blood was collected for biochemical test. Three single nucleotide polymorphisms(SNPs) of NLRP3 and TLR4 were detected with multiplex ligase assay reaction, and logistic regression analysis was applied to compare the correlation between NLRP3 and TLR4 alleles and gout risk. The interaction of SNP and TyG index with gout was analyzed by generalized multi-factor dimensionality reduction(GMDR) model and logistic regression.Results:After adjusting for smoking, drinking, and other factors, the risk of gout increased by 61.1% for each standard deviation increase in TyG index. CC genotypes of rs10754558, rs10759932, and rs7525979 were high risk genotypes of gout in Han ethnicity. GMDR results showed significant differences in the interaction models of rs10754558-TyG index, rs7525979-TyG index, and rs10759932-TyG index between control group and gout group( P<0.05), suggesting an interaction between the three genotypes of SNPs selected and TyG index. Stratified analysis of the three selected SNPs and TyG index showed that after adjusting for age, smoking, and other factors, the high TyG index patients carrying C/C or C/G genotype at rs10754558 displayed an increased risk of gout compared with those carrying GG genotype and low TyG index( OR=2.127, P<0.05). Conclusion:The CC genotypes of rs10754558, rs10759932, and rs7525979 are high risk genotypes for gout in Han ethnicity. The interaction between rs10754558 and TyG index may increase the risk of gout development.

Construction and validation of a Nomogram-based prediction model for the risk of gout in men / 中华内分泌代谢杂志

Objective:To investigate the risk factors of gout and establish a columnar graph model to predict the risk of gout development.Methods:A total of 1 032 Han Chinese men attending the Affiliated Hospital of Traditional Chinese Medicine of Xinjiang Medical University, People′s Hospital of Xinjiang Uygur Autonomous Region, and the First Affiliated Hospital of Xinjiang Medical University from 2018 to 2020 were selected as study subjects and divided into training set(722 cases)and validation set(310 cases)by simple random sampling method in the ratio of 7∶3. General information and biochemical indices of the subjects were collected. The collected information was used to assess the risk of gout prevalence. LASSO regression analysis of R Studio software was used to screen the best predictors, and was introduced to construct a column line graph model for predicting gout risk using receiver operating characteristic(ROC)curves, and the Hosmer-Lemeshow test was used to assess the discrimination and calibration of the column line graph model. Finally, decision curve analysis(DCA)was performed using the rmda program package to assess the clinical utility of the model in validation data.Results:Age, uric acid, body mass index, total cholesterol, and waist-to-hip ratio were risk factors for gout( P<0.05). The column line graph prediction model based on the above five independent risk factors had good discrimination(AUC value: 0.923 for training set validation and 0.922 for validation set validation)and accuracy(Hosmer-Lemeshow test: P>0.05 for validation set validation); decision curve analysis showed that the prediction model curve had clinical practical value. Conclusion:The nomogram model established by combining age, uric acid, body mass index, total cholesterol, and waist-to-hip ratio indicators can predict the risk of gout more accurately.

Clinical characteristics and genetic analysis of a case with adult neuronal ceroid lipofuscinosis type 7 due to variant of MFSD8 gene / 中华医学遗传学杂志

OBJECTIVE@#To explore the clinical characteristics and genetic variants in a patient with adult ceroid lipofuscinosis neuronal type 7 (ACLN7).@*METHODS@#A female patient diagnosed with ACLN7 in Henan Provincial People's Hospital in June 2021 was selected as the study subject. Clinical data, auxiliary examination and result of genetic testing were retrospectively analyzed.@*RESULTS@#The patient, a 39-year-old female, has mainly presented progressive visual loss, epilepsy, cerebellar ataxia and mild cognitive decline. Neuroimaging analysis has revealed generalized brain atrophy, prominently cerebellum. Fundus photography has revealed retinitis pigmentosa. Ultrastructural skin examination has revealed granular lipofuscin deposits in the periglandular interstitial cells. Whole exome sequencing revealed that she has harbored compound heterozygous variants of the MSFD8 gene, namely c.1444C>T (p.R482*) and c.104G>A (p.R35Q). Among these, c.1444C>T (p.R482*) was a well established pathogenic variant, while c.104G>A (p.R35Q) was a missense variant unreported previously. Sanger sequencing confirmed that the daughter, son and elder brother of the proband have respectively carried heterozygous c.1444C>T (p.R482*), c.104G>A (p.R35Q), and c.104G>A (p.R35Q) variants of the same gene. The family has therefore fit with the autosomal recessive inheritance pattern of the CLN7.@*CONCLUSION@#Compared with previously reported cases, this patient has the latest onset of the disease with a non-lethal phenotype. Her clinical features have involved multiple systems. Cerebellar atrophy and fundus photography may be indicative of the diagnosis. The c.1444C>T (p.R482*) and c.104G>A (p.R35Q) compound heterozygous variants of the MFSD8 gene probably underlay the pathogenesis in this patient.

Comparative study on the effects of total ginkgo flavonol glycosides and total ginkgolides on neurofunctional recovery in mice with subacute stroke / 药学学报

As a Ginkgo biloba extract preparation, shuxuening injection has a unique advantage in the prevention and treatment of acute and subacute stroke, but its main active ingredient is still unclear. Using a subacute model of stroke in mice constructed earlier, we further explored the contribution and mechanism of the two main components of total ginkgo flavonol glycosides and total ginkgolides in facilitating the neurofunctional recovery in stroke-induced mice. The pharmacodynamics was mainly evaluated by neurobehavioral changes, cerebral infarction volume, blood-brain barrier permeability and brain edema. The pathway and targets were predicted by transcriptome and network pharmacology. Finally, the mechanism was verified at the mRNA and protein levels. The results showed that the beneficial effect of total ginkgolides was greater than that of total ginkgo flavonol glycosides in both the pharmacodynamics and the regulatory mechanism of granulocyte adhesion and diapedesis involving granulocyte colony-stimulating factor (G-CSF), macrophage-1 antigen (MAC-1) and E-selectin. These findings suggest that shuxuening injection may improve the prognosis for mice with subacute stroke by down-regulating G-CSF-mediated granulocyte adhesion and diapedesis pathway mainly through the total ginkgolide components. This finding is expected to provide reference for optimizing prescription and searching for natural drugs for targeting the treatment of ischemic stroke prognosis. The animal experiments in this study followed the regulations of Animal Ethics Committee of Tianjin University of Traditional Chinese Medicine.

A Chinese pedigree of familial encephalopathy with neuroserpin inclusions bodies / 中华神经科杂志

Objective:To report the clinical and genetic features of a pedigree with familial encephalopathy with neuroserpin inclusions bodies (FENIB) and to enhance the understanding of the disease.Methods:The proband was admitted to Department of Neurology, Henan Provincial People′s Hospital in June 2020 due to cognitive impairment and epilepsy. Detailed medical history inquiry, physical examinations, and neuroimaging examination of the family were conducted. The proband completed the examination of brain magnetic resonance imaging (MRI), electroencephalogram (EEG), cerebrospinal fluid examinations. Whole exome sequencing and Sanger sequencing were used to screen the genetic variations in the proband. Sanger sequencing was performed in some family members to verify the mutation. Through literature review, the characteristics of the disease were summarized.Results:The proband was a 23-year-old young female with progressive cognitive impairment, epilepsy as the main manifestations. Brain MRI indicated moderate atrophy of bilateral cerebral cortex. Genetic sequencing revealed a heterozygous missense mutation (c.1013A>G; p.H338R) of SERPINI1 gene encoding the neuroserine protease inhibitor protein. The proband′s mother and brother had similar clinical symptoms in adolescence. Both of them passed away several years later. This mutation was a proven pathogenic mutation for FENIB. The clinical phenotype was consistent within the family. Genotype and clinical phenotype were co-segregated.Conclusion:FENIB due to SERPINI1 gene mutations should be considered in young cases of cognitive decline, epilepsy and myoclonus.

As the final destination of various cardiovascular abnormalities, heart failure is one of the diseases with the highest morbidity and mortality in the world. Due to its complicated pathogenesis, people urgently need to find new targets and effective treatment. Imbalance in myocardial energy metabolism, an important molecular biological basis for heart failure, affects the contractile and diastolic functions of the heart. As the main source of energy synthesis in cardiomyocytes and an important participant in various signaling pathways, mitochondria plays an indispensable role in the process of cell survival and death and has been considered as a critical target for the treatment of heart failure. Traditional Chinese medicine has a great effect on the treatment of heart failure through multi-components, multi-targets, and multi-channels. In recent years, more and more researches regard mitochondria as the target of traditional Chinese medicine in the treatment of heart failure, and have achieved significant results in improving mitochondrial function, increasing energy metabolism and energy supplement for cardiomyocytes, and resisting against oxidative stress. In this article, researches on the regulation of mitochondria in the treatment of heart failure by traditional Chinese medicine are reviewed from four aspects: mitochondrial biogenesis; mitochondrial electron transport chain and reactive oxygen species(ROS) production; metabolic substrates and metabolic enzymes; and calcium ion transport in the mitochondria. It provides a basis for further research and clinical application in the future.

Application prospect of organoids and 3D-cell models in evaluation of cardiotoxicity of traditional Chinese medicine / 药学学报

Effect of target systolic blood pressure on cardiovascular events in patients with hypertension complicated with type 2 diabetes / 中国实用护理杂志

Objective To compare the effects of target systolic blood pressure on cardiovascular events in patients with hypertension and type 2 diabetes after antihypertensive drugs. Methods This study was a retrospective cohort study. Randomly selected from March 2014 to March 2017, 1563 patients with hypertension and type 2 diabetes diagnosed in the Department of Cardiology of the Tiemei Group General Hospital. There was no cardiovascular complications at admission. After admission, the population variables of each patient were recorded. Each patient was adjusted for blood pressure and blood glucose according to the doctor's advice after admission. After the hospital was discharged, the patient was followed up for blood pressure every week. The follow-up was 3-4 months. The average systolic blood pressure of each patient was recorded as the target systolic pressure. The patients who were followed up were divided into three groups according to the target systolic pressure value, namely ≤120 mmHg(1 mmHg=0.133 kPa) group,>120-130 mmHg group,>130-140 mmHg group. After that, it was changed to a weekly telephone follow-up of the nurses for a total of 3 years. The cardiovascular disease (CVD) occurred in these patients within 3 years were recorded. The CVD was used as the dependent variable, and the systolic blood pressure of each group was used as the independent variable to do COX. Proportional risk regression analysis, the hazard ratio (HR) of each group of concurrent CVD. Taking CVD as the dependent variable, HR of CVD with >130-140 mmHg group was taken as the reference value, and all population variables were used as independent variables, respectively, ≤120 mmHg group,>120-130 mmHg group and>130-140 mmHg group combined with CVD risk ratio. Results During the 3-year follow-up period, 1401 patients with blood pressure met: 104 patients with systolic blood pressure ≤120 mmHg, 543 patients with >120-130 mmHg, and 754 patients with >130-140 mmHg. The incidence of CVD in the three groups was 14.4％(15/104), 8.8％(48/543), 7.0％(53/754). HR of CVD were 1.66, 0.96, 0.53 in≤120 mmHg group,>120- 130 mmHg group,>130-140 mmHg group .Compared with >130-140 mmHg group, the risk ratio of CVD in all subgroups of≤120 mmHg group was statistically increased (HR>1, P<0.05). Compared with >130-140 mmHg, >120-130 mmHg group with 65-79 years old, combined with more than 3 groups of antihypertensive drugs, patients with diuretics showed a statistically significant increase in the risk ratio of CVD (HR>1, P <0.05). Conclusions The target systolic blood pressure of patients with hypertension and type 2 diabetes should be >130-140 mmHg. For patients aged 65-79 years, more than 3 groups of antihypertensive drugs are used. Patients with diuretics should have a target systolic blood pressure of >130-140 mmHg.

The positive rates in the first and second screening tests were 9.52% and 2.01%, respectively, in girls, which were significantly higher than those in boys (3.79% and 0.23%, respectively; P<0.05). Among the children who had positive test results in the second screening, 302 (0.81%) were diagnosed with urinary system diseases.</p><p><b>CONCLUSIONS</b>Urine screening is an effective way for the early detection of some occult kidney diseases, which provides great benefits for early prevention and treatment of kidney diseases in children.</p>

Expression of Beclin1, LC3 and mTOR and their significance in colorectal carcinoma / 临床与实验病理学杂志

Purpose To investigate the expression of Beclin1, LC3 and mTOR in colorectal cancer ( CRC) and their significance. Methods Immunohistochemistry, Western blot and real-time PCR were employed to detect the expression of Beclin1, LC3 and mTOR in CRC. Results The positive expression rate of Beclin1, LC3 and mTOR in 242 cases of CRC was 90. 50%, 87. 19% and 46. 28%, respectively, which were higher than that in adjacent tissues ( P0. 05). The expres-sion of LC3 was positively correlated with Beclin1 and negatively correlated with mTOR in colorectal cancer (rs =0. 593, P0. 05). Kaplan-Meier survival analysis re-vealed that the five-year survival rate of patients without nodal metastasis, positive expression of Beclin1, LC3 and negative expression of mTOR was higher than those with nodal metastasis, negative expression of Beclin1 and LC3, and positive expression of mTOR. Cox survival analysis results revealed that LC3, mTOR and lymphnode metastasis were independent prognostic factors. The results of IHC, real-time PCR and Western blot in fresh CRC tissues indicated that the expression of Beclin1, LC3 and mTOR in colorectal cancer was significantly higher than that in adjacent tissues (P<0. 05). Conclusions The aberrant expression of Beclin1, LC3 and mTOR may be associated with the development and progression of colorectal cancer. The simultaneous detection of Beclin1, LC3 and mTOR genes in colorectal cancer may be helpful for the evaluation of the progressive degree and the judgment of prognosis.
