ABSTRACT

Background@#The association of serum retinol-binding protein (RBP) levels with nonalcoholic fatty liver disease (NAFLD) remains controversial. Furthermore, few studies have investigated their relationship in type 2 diabetes mellitus (T2DM) patients. Therefore, the aim of the present study was to explore the association between serum RBP levels and NAFLD in Chinese inpatients with T2DM. @*Methods@#This cross-sectional, real-world study included 2,263 Chinese T2DM inpatients. NAFLD was diagnosed by abdominal ultrasonography. The subjects were divided into four groups based on RBP quartiles, and clinical characteristics were compared among the four groups. The associations of both RBP levels and quartiles with the presence of NAFLD were also analyzed. @*Results@#After adjustment for sex, age, and diabetes duration, there was a significant increase in the prevalence of NAFLD from the lowest to the highest RBP quartiles (30.4%, 40.0%, 42.4%, and 44.7% for the first, second, third, and fourth quartiles, respectively, P<0.001 for trend). Fully adjusted multiple logistic regression analysis revealed that both increased RBP levels (odds ratio, 1.155; 95% confidence interval, 1.012 to 1.318; P=0.033) and quartiles (P=0.014 for trend) were independently associated with the presence of NAFLD in T2DM patients. @*Conclusion@#Increased serum RBP levels were independently associated with the presence of NAFLD in Chinese T2DM inpatients. Serum RBP levels may be used as one of the indicators to assess the risk of NAFLD in T2DM patients.

ABSTRACT

Objective To identify the species of trematodes isolated from laying ducks in Nanchang City using morphological and molecular approaches. Methods Trematodes were isolated from the hepatobiliary duct, gallbladder and large intestine of market-sold laying ducks in Nanchang City. Following morphological characterization, total DNA was extracted from all trematode specimens, and internal transcribed spacer region (ITS) and cytochrome C oxidase subunit 1 (Cox1) genes were amplified using PCR assay and sequenced. Sequence alignment was performed using the Blast software, and homology and phylogenetic analyses were done in the trematode isolates based on ITS and Cox1 gene sequences. Results The morphological characteristics of two trematode isolates from the large intestine of laying ducks were similar to those of Echinostoma revolutum and E. miyagawai, and the morphological characteristics of eight trematode samples isolated from the hepatobiliary duct and gallbladder of laying ducks were similar to those of Amphimerus anatis. The ITS and Cox1 gene sequences of the two trematode isolates from the large intestine of laying ducks had 99.3% and 98.9%-99.4% homology with E. miyagawai, and the phylogenetic analysis showed that two trematode isolates had the closest genetic relationship with E. miyagawai based on ITS and Cox1 gene sequences. The ITS gene sequences of eight trematode isolates from the hepatobiliary duct and gallbladder of laying ducks shared 95.1%-95.5% with Opisthorchis sudarikovi and Clonorchis sinensis, while the Cox1 gene sequences of eight trematode isolates from the hepatobiliary duct and gallbladder of laying ducks shared 86.3%-86.4% and 85.5%-85.7% with O. viverrini and O. sudarikovi. ITS gene sequence-based phylogenetic analysis showed that the duck-derived trematode isolates had the closest genetic relationship with C. sinensis, and Cox1 gene sequence-based phylogenetic analysis showed that the duck-derived trematode isolates had the closest genetic relationship with Metorchis orientalis and O. viverrini. Conclusions The trematode isolates from the large intestine of laying ducts in Nanchang City may be E. miyagawai, and the trematode isolates from the hepatobiliary duct and gallbladder may be an unidentified trematode species of the family Opisthorchiidae.

ABSTRACT

Objective:To analyze the clinical characteristics and risk factors of clopidogrel resistance after intracranial arterial stent implantation in patients with ischemic cerebrovascular disease.Methods:Retrospective case-control study was used.A total of 360 patients with ischemic cerebrovascular disease hospitalized in Beijing Tiantan Hospital from January 2017 to December 2018 were selected.All patients received intracranial arterial stenting and received double anti-platelet drugs after operation.Patients were divided into clopidogrel resistance group and non-resistance group according to the inhibition rate of platelet aggregation measured by thromboelastography.Clinical data and laboratory indicators of patients in the two groups were compared using two independent sample T tests and Mann-Whitney U tests, and possible risk factors of clopidogrel resistance were analyzed by Logistic regression.Results:White blood cell (WBC) count, neutrophils count, lymphocyte count, cholesterol, LDL cholesterol, and serum homocysteine levels in the clopidogrel non-resistant group were (6.58±1.45)×10 9/L, (4.01±1.05)×10 9/L, 1.83(1.49, 2.23)×10 9/L, (3.63±0.85) mmol/L, 1.93(1.53, 2.31) mmol/L, and 14.3(11.80, 17.00) μmol/L, respectively.Compared with the clopidogrel non-resistant group, the WBC count, neutrophils count, lymphocyte count, cholesterol, LDL cholesterol and serum homocysteine levels in the clopidogrel resistant group were all higher (7.19±1.53) ×10 9/L, (4.40±1.05) ×10 9/L, 2.03(1.63, 2.58)×10 9/L, (4.02±0.99) mmol/L, 2.04(1.68, 2.78) mmol/L and 15.90(12.25, 22.20) μmol/L, respectively.The difference was statistically significant ( t=3.277, t=2.867, Z=2.457, t=3.409, Z=2.705 and Z=2.220, respectively; P value were 0.001, 0.004, 0.014, 0.001, 0.007 and 0.026, respectively). Logistic regression analysis showed that high serum homocysteine ( OR=1.031, 95% CI 1.006-1.057, P=0.015) was an independent risk factor for clopidogrel resistance. Conclusion:Patients with clopidogrel resistance have high leucocyte, blood lipid, homocysteine and other clinical characteristics.High serum homocysteine is an independent risk factor for clopidogrel resistance.

ABSTRACT

Objective:To evaluate the effect of self-management treatment for patients with chronic Keshan disease in Gansu Province.Methods:From March to June 2018, 243 patients with chronic Keshan disease who were treated by self-management treatment outside the hospital in 7 Keshan disease counties in Gansu Province were selected as the survey subjects, and their general demographic and clinical data were collected. At the same time, the survey subjects were given a 6-month self-management treatment, and the self-management scale was used to evaluate the patients' self-management behavior before treatment and 6 months after treatment. The higher the score, the better the patients' self-management behavior. The influencing factors of self-management scale were analyzed by multiple linear regression analysis.Results:Excluding incomplete data, a total of 158 patients with chronic Keshan disease were included in this survey, including 96 males and 62 females. Compared with patients before self-management treatment, the patients' cardiac function classification and work ability improved significantly after 6 months of self-management treatment ( Z = - 4.685, - 5.934, P < 0.05); cardiothoracic ratio decreased (0.61 ± 0.08 vs 0.63 ± 0.09, t = 5.175, P < 0.05); in the cardiac color Doppler ultrasound indexes, left ventricular ejection fraction (LVEF) and left ventricular fractional shortening (LVFS) were increased (0.41 ± 0.11 vs 0.36 ± 0.07, 0.21 ± 0.07 vs 0.18 ± 0.05, t = - 6.504, - 5.391, P < 0.05); the total score of the self-management scale was increased [(53.86 ± 9.29) scores vs (51.46 ± 10.50) scores, t = - 3.696, P < 0.05]. Further analysis of the efficacy of the patients' cardiac function classification showed that the patients' medication compliance was positively correlated with the efficacy of the cardiac function classification ( r = 0.243, P < 0.05). The result of multiple linear regression analysis showed that education level and efficacy of the cardiac function classification were influencing factors of the self-management scale for patients with chronic Keshan disease ( t = 2.466, 2.635, P < 0.05). Conclusion:The self-management treatment for patients with chronic Keshan disease can effectively improve heart function and improve self-management behavior.

ABSTRACT

Mammalian catechol-O-methyltransferases(COMT)are an important class of conjugative enzymes,which play a key role in the metabolism and inactivation of catechol neurotransmitters,catechol es-trogens and a wide range of endobiotics and xenobiotics that bear the catechol group.Currently,COMT inhibitors are used in combination with levodopa for the treatment of Parkinson's disease in clinical practice.The crucial role of COMT in human health has raised great interest in the development of more practical assays for highly selective and sensitive detection of COMT activity in real samples,as well as for rapid screening and characterization of COMT inhibitors as drug candidates.This review summarizes recent advances in analytical methodologies for sensing COMT activity and their applications.Several lists of biochemical assays for measuring COMT activity,including the probe substrates,along with their analytical conditions and kinetic parameters,are presented.Finally,the challenges and future perspec-tives in the field,such as visualization of COMT activity in vivo and in situ,are highlighted.Collectively,this review article overviews the practical assays for measuring COMT activities in complex biological samples,which will strongly facilitate the investigations on the relevance of COMT to human diseases and promote the discovery of COMT inhibitors via high-throughput screening.

ABSTRACT

Autism spectrum disorder(ASD)is a kind of neurodevelopmental disorder.Despite the high prevalence of ASD, no definite pathogenesis of ASD has yet been elucidated to date.Accumulating evidence indicated that the pathogenesis of ASD may be related to genetic, environmental and immune factors.Studies has been shown that vitamin D(Vit D)deficiency is negatively correlated with the prevalence of ASD, and that supplementation with Vit D may reduce the risk of ASD.Because of the extensive physiological functions of Vit D, it can act as a steroid hormone in multiple aspects such as genetic, environment and immune profiles.Meanwhile, the genetic, environmental and immune changes could also affect the metabolism and function of Vit D, and vice versa.Therefore, Vit D deficiency probably lead to the development of ASD.This review focuses on the relationship between Vit D and environmental, genetic and immune factors of ASD.

ABSTRACT

Mechanosensitive ion channels are mechanoreceptors that convert mechanical stimulation on the cell surface into intracellular electrical signal or chemical signal. In recent years, Piezo protein as a mechanically activated cation channel in eukaryotes has gradually become a research hotspot. Piezo1 and Piezo2 proteins are expressed in different organs and tissues of mammals, and tissues such as bones and joints are directly related to mechanical conduction. The intracellular effects caused by the conduction of mechanical force play a very important role in the treatment and prevention of orthopedic diseases. In this paper, the researches on Piezo protein mechanically activated cation channels in bone tissue, cartilage tissue, bone marrow tissue, intervertebral disc tissue and orthopedic diseases were reviewed.

ABSTRACT

Objective:To explore the effect of Shenqi Maiwei Dihuangtang (SQMWDH) combined with acarbose on the level of 2-hour oral glucose tolerance test (2 h OGTT),body mass index (BMI), and abdominal fat thickness in patients with impaired glucose tolerance (IGT). Method:A total of 130 patients with IGT admitted to the First People's Hospital of Shuangliu District from February 2017 to January 2019 were divided into a control group and a treatment group by a random number table. All patients received conventional treatment, such as diet regulation and exercise. The patients in the control group received additional oral administration of acarbose,while those in the treatment group were treated with SQMWDH based on the control group. Fasting blood glucose (FBG),2 h OGTT, and glycated hemoglobin A1c(HbA1c)levels were measured by the blood glucose meter. Abdominal fat thickness was measured by ultrasound tomography,and serum total cholesterol (TC),triglyceride (TG),adiponectin, and leptin levels in fasting venous blood were measured. Result:After treatment,the total response rate of the treatment group was higher than that of the control group (95.00% vs. 81.67%, <italic>χ</italic><sup>2</sup>=5.175,<italic>P</italic><0.05). Before treatment,there was no significant difference in FBG,2 h OGTT,HbA1c, BMI,waist circumference,abdominal fat thickness,TC,TG,adiponectin, and leptin of IGT patients between the two groups. After treatment,the levels of FBG,2 h OGTT,HbA1c, BMI,waist circumference,abdominal fat thickness,TC,TG,and leptin of IGT patients were lower than those before treatment in both groups (<italic>P</italic><0.05), and the treatment group was inferior to the control group(<italic>P</italic><0.05,<italic>P</italic><0.01). The level of adiponectin after treatment was higher than that before treatment in both groups (<italic>P</italic><0.05),and the treatment group was superior to the control group (<italic>P</italic><0.05). Conclusion:SQMWDH combined with acarbose is effective in treating IGT patients by effectively reducing 2 h OGTT and abdominal fat thickness to alleviate obesity and improve the constitution of patients.

ABSTRACT

Objective:To observe the relationship of ventilatory efficiency to cardiac function, especially heart rate recovery after exercise for patients with chronic obstructive pulmonary disease (COPD). Methods:From January, 2019 to December, 2020, 190 patients with COPD were recruited for Cardiopulmonary Exercise Testing. The general condition, medical history and medication history, lung function test and parameters of Cardiopulmonary Exercise Testing were recorded. They were divided into normal group and delay group according to whether the heart rate decline more than twelve beats within a minute after Cardiopulmonary Exercise Testing. Results:There were 89 patients (46.84%) in the delay group. Compared with the normal group, the delay group were older (Z = 2.282, P < 0.05), with less ratio of force exiratory volume in the first second in prediction (FEV1.0%) (Z = 3.626, P < 0.001), maximum power (t = 5.547, P < 0.001), breath reserve (BR) (t = 2.122, P < 0.05) and higher minimum ventilation equivalent of carbon dioxide (VE/VCO2nadir) (Z = 3.296, P = 0.001). Logistic regression showed that the COPD severity, VE/VCO2nadir and BR correlated with heart rate recovery. After adjusting for gender, age, body mass index and COPD severity, VE/VCO2nadir was an independent risk factor for delayed heart rate recovery (OR = 1.203, 95%CI 1.032 to 1.873, P = 0.004), and the best cut-off point was 33.15 (AUC = 0.6387, 95%CI 0.5595 to 0.7178, P = 0.001). Conclusion:The ventilatory inefficiency may increase the risk of abnormal heart rate recovery after exercise in COPD patients.

ABSTRACT

Since 2015 when the transmission of schistosomiasis was controlled in China, the country has been moving towards elimination of schistosomiasis, with the surveillance-response as the main interventions for schistosomiasis control. During the period of the 13th Five-Year Plan, the transmission of schistosomiasis had been interrupted in four provinces of Sichuan, Jiangsu, Yunnan and Hubei and the prevalence of schistosomiasis has been at the historically lowest level in China. As a consequence, the goal set in The 13th Five-Year National Schistosomiasis Control Program in China is almost achieved. However, there are multiple challenges during the stage moving towards elimination of schistosomiasis in China, including the widespread distribution of intermediate host snails and complicated snail habitats, many types of sources of Schistosoma japonicum infections and difficulty in management of bovines and sheep, unmet requirements for the current schistosomiasis control program with the currently available tools, and vulnerable control achievements. During the 14th Five-Year period, it is crucial to consolidate the schistosomiasis control achievements and gradually solve the above difficulties, and critical to provide the basis for achieving the ultimate goal of elimination of schistosomiasis in China. Based on the past experiences from the national schistosomiasis control program and the challenges for schistosomiasis elimination in China, an expert consensus has been reached pertaining to the objectives, control strategy and measures for The 14th Five-Year National Schistosomiasis Control Program in China, so as to provide insights in to the development of The 14th Five-Year National Schistosomiasis Control Program in China.

ABSTRACT

Since the concept of "safe area" put forward by Lewinnek, it has been widely recognized. While in recent years, many scholars have found that even if the acetabular prosthesis was placed on the "safe area", there were still many unexplained dislocation after total hip arthroplasty. And scholars began to question whether the "safe area" is really suitable for all patients. Spinal degeneration, deformity, lumbar fusion, etc. will lead to spine sagittal imbalance and changes in pelvic activity, which could lead to changes in acetabular orientation, and ultimately lead to edge loading, wear, impact, and even dislocation after total hip replacement. From the perspective of wear, impact and dislocation, it is determined by the functional positioning of the acetabular cup, not the anatomical positioning. The anatomical positioning and functional positioning of the neutral pelvic acetabular cup in the standing position can be considered equivalent. For pelvic rotation more than 20°, functional placement needs to be considered. In recent years, as the understanding of the internal relationship between the spine-pelvis-hip joint has become more and more profound, some scholars further classify the hip-spine relationship according to whether the spine is stiff or deformed, and propose corresponding acetabulums according to different types of hip-spine relationships The function of placement, so as to achieve a stable artificial hip joint. Therefore, it is of great significance to fully assess whether the patient's sagittal plane is balanced before surgery to guide artificial hip replacement surgery.

ABSTRACT

The incidence of malignant melanoma, a highly fatal skin tumor, is on the rise worldwide. Melanomas are highly aggressive and have strong metastatic capability that leads to lethality. Recurrence occurs in patients with distant metastases, even with the latest treatments, and median survival is only a few months. At present, the prevention and treatment of melanoma includes surgical resection, chemotherapy, immunotherapy and targeted therapy. However, these strategies can lead to drug resistance and adverse effects. In recent years, an increasing number of studies have found that natural products have effective anti-melanoma activities, including inhibition of tumor growth, induction of cell apoptosis, inhibition of angiogenesis and metastasis and toxicity to tumor stem cells. In addition, several studies have reported that the combination of natural products and traditional anti-melanoma drugs can enhance the therapeutic efficacy. In this review we summarize the prevention and treatment of melanoma with natural products.

ABSTRACT

To investigate the feasibility and safety of endoscopic trans-gastric cholecystolithotomy(ETGC) combined with endoscopic retrograde cholangiopancreatography (ERCP) for cholecystolithiasis and choledocholithiasis. Data of patients with cholecystolithiasis and choledocholithiasis who underwent ETGC after ERCP in Zhongshan Hospital Affiliated to Fudan University from November 2018 to April 2019 were analyzed. Six patients with cholecystolithiasis and choledocholithiasis, 4 males and 2 females, were included in this study.The interval between ERCP and ETGC ranged from 1 to 77 days (median 5 days). All the 6 patients successfully completed ETGC after ERCP, with a surgical success rate of 100%. All the patients had multiple cholecystolithiasis and one patient was complicated with gallbladder polyps.The ETGC operation time was 22-100 min (median 65 min), and the length of hospital stay was 3-9 d (median 6.5 d). Two patients had dull pain in the upper abdomen and increased body temperature after surgery. Abdominal ultrasound in one patient suggested local effusion in the right upper abdomen.Both patients improved after conservative treatment.None of the patients had cholecystitis and cholangitis related symptoms such as right upper abdominal pain or fever during postoperative follow-up, and the follow-up rate was 100%with median follow-up time of 18 month.All the 6 patients underwent abdominal ultrasound examination after surgery. No recurrence occurred in 5 patients. One of the patients showed cholesterol crystals in the gallbladder wall and bile mud deposition.ETGC combined with ERCP is safe and feasible for cholecystolithiasis and choledocholithiasis.

ABSTRACT

Objective:To evaluate biological dose and retrospective biodosimetry of a case of large area back skin injury caused by suspected interventional procedure.Methods:Peripheral blood from the patient was collected at about 7 months after interventional procedure, and the chromosomal aberrations in peripheral blood cells were analyzed to evaluate the retrospective biodosimetry using the correction factor of dose estimation, Dolphin′s model and Qdr method, respectively. Results:Based on the amounts of semi-automated dic and manually detected dic plus ring, the whole-body average absorbed dose of the victim was estimated to be 0.68-0.95 Gy by four different dose response curves. Over dispersion of dic or dic plus ring was also detected, and the efficiency of dose assessment was obviously increased using dic semi-automatic detection. Based on three different retrospective biodosimetry models, the estimated average absorbed dose was further corrected to be between 1.80-2.86 Gy, which was consistent with clinical diagnosis of degree Ⅳ radiation skin injury.Conclusions:A case of suspected radiation skin injury was confirmed by chromosomal aberration analysis and it’s biodosimetry was reconstructed, suggesting that the unstable chromosomal aberration analysis may be applicable to assess the retrospective biodosimetry of non-uniform local radiation exposure.
