ABSTRACT

Background@#Subclinical hypothyroidism (SCH) is the most common thyroid dysfunction, and its relationship with blood pressure (BP) has been controversial. The aim of the study was to analyze the association between SCH and newly-diagnosed hypertension. @*Methods@#Based on data from the Thyroid disease, Iodine nutrition and Diabetes Epidemiology (TIDE) study, 49,433 euthyroid individuals and 7,719 SCH patients aged ≥18 years were enrolled. Patients with a history of hypertension or thyroid disease were excluded. SCH was determined by manufacturer reference range. Overall hypertension and stage 1 and 2 hypertension were diagnosed according to the guidelines issued by the American College of Cardiology/American Heart Association in 2017. @*Results@#The prevalence of overall hypertension (48.7%), including stage 1 (28.9%) and 2 (19.8%) hypertension, increased significantly in SCH patients compared with euthyroid subjects. With elevated serum thyroid stimulating hormone (TSH) level, the hypertension prevalence also increased significantly from the euthyroid to different SCH subgroups, which was more profound in females or subjects aged <65 years. The age- and sex-specific regression analysis further demonstrated the same trends in the general population and in the 1:1 propensity matched population. Similarly, several BP components (i.e., systolic, diastolic, and mean arterial BP) were positively associated with TSH elevation, and regression analysis also confirmed that all BP components were closely related with SCH in female subjects aged <65 years. @*Conclusion@#The prevalence of hypertension increases for patients with SCH. SCH tends to be associated with hypertension and BP components in females younger than 65 years.

ABSTRACT

The present study investigated the differences in pharmacokinetics and intestinal absorption of six alkaloids in Sanmiao Pills and Simiao Pills in rats and explored the different efficacies of the two formulae. After oral administration of Sanmiao Pills and Simiao Pills in rats, blood samples were collected at different time points. Samples were prepared for the determination of six alkaloids in plasma by UPLC-MS/MS. The chromatography was performed on an ACE Excel 3 C_(18 )column with acetonitrile-0.1% formic acid in water as the mobile phase for gradient elution. Analytes were detected in the positive ion mode. Plasma concentrations and pharmacokinetic parameters were calculated. Intestinal absorption of alkaloids was investigated by single-pass intestinal perfusion and absorption parameters of ingredients were calculated. The results showed that the UPLC-MS/MS method for simultaneous determination of concentrations of six alkaloids in plasma was developed and validated by methodological investigations, such as specificity, calibration curves, precision, accuracy, recovery, matrix effect, and stability. The results of the pharmacokinetic assay revealed that C_(max) and AUC values of phellodendrine, berberine, magnoflorine, berberrubine, and jatrorrhizine in Simiao Pills were significantly increased, and CL/F values were reduced as compared with those in Sanmiao Pills, which indicated the increase in plasma concentrations of alkaloids. The intestinal absorption parameters K_(a )and P_(eff) values of phellodendrine, berberine, and jatrorrhizine in Simiao Pills were higher than those in Sanmiao Pills. The intestinal absorption and plasma concentrations of alkaloids in Simiao Pills were significantly higher than those in Sanmiao Pills, suggesting that the composition of Simiao Pills was more conducive to the alkaloids into the blood to resist inflammation and lower uric acid.

ABSTRACT

Objective@#The relationship between serum uric acid (SUA) levels and glycemic indices, including plasma glucose (FPG), 2-hour postload glucose (2h-PG), and glycated hemoglobin (HbA1c), remains inconclusive. We aimed to explore the associations between glycemic indices and SUA levels in the general Chinese population.@*Methods@#The current study was a cross-sectional analysis using the first follow-up survey data from The China Cardiometabolic Disease and Cancer Cohort Study. A total of 105,922 community-dwelling adults aged ≥ 40 years underwent the oral glucose tolerance test and uric acid assessment. The nonlinear relationships between glycemic indices and SUA levels were explored using generalized additive models.@*Results@#A total of 30,941 men and 62,361 women were eligible for the current analysis. Generalized additive models verified the inverted U-shaped association between glycemic indices and SUA levels, but with different inflection points in men and women. The thresholds for FPG, 2h-PG, and HbA1c for men and women were 6.5/8.0 mmol/L, 11.0/14.0 mmol/L, and 6.1/6.5, respectively (SUA levels increased with increasing glycemic indices before the inflection points and then eventually decreased with further increases in the glycemic indices).@*Conclusion@#An inverted U-shaped association was observed between major glycemic indices and uric acid levels in both sexes, while the inflection points were reached earlier in men than in women.

ABSTRACT

This study aimed to propose an operational definition of late-onset hypogonadism (LOH) that incorporates both clinical symptoms and serum testosterone measurements to evaluate the prevalence of LOH in aging males in China. A population-based sample of 6296 men aged 40 years-79 years old was enrolled from six representative provinces in China. Serum total testosterone (TT), sex hormone-binding globulin (SHBG), and luteinizing hormone (LH) were measured and free testosterone (cFT) was calculated. The Aging Males' Symptoms (AMS) scale was used to evaluate the LOH symptoms. Finally, 5078 men were included in this analysis. The TT levels did not decrease with age (P = 0.59), and had no relationship with AMS symptoms (P = 0.87 for AMS total score, P = 0.74 for ≥ 3 sexual symptoms). The cFT levels decreased significantly with age (P < 0.01) and showed a negative association with the presence of ≥ 3 sexual symptoms (P = 0.03). The overall estimated prevalence of LOH was 7.8% (395/5078) if a cFT level <210 pmol l

METHODS :From Sept. to Dec. 2019, an electronic questionnaire survey was conducted amongpharmacists of all of 126 listed DTP pharmacies and involved wang_star@163.com education background ,professional knowledge sources andpharmaceutical care ability (such as prescription checking and E-mail:dujoan-88@163.com dispensing,medication consultation and guidance ,medication management,follow-up),pharmaceutical knowledge of antitumor medicine ,etc. DTP pharmacies in C hina were inspected on site , and their pharmaceutical care management were evaluated ,and impression of on-site inspection were discribed with questionnaire survey. The current situation of oncology pharmaceutical care ability of DTP pharmacy in China was evaluated and corresponding suggestions were put forward. RESULTS :A total of 400 questionnaires were sent out ,and 392 valid questionnaires were collected with recovery rate of 98.0%. The cancer pharmacists in DTP pharmacy were mainly from East China ,mainly in Jiangxi (73 persons,18.62%),Anhui(68 persons,17.35%). The pharmacists were mainly junior college or below (229 persons,58.42%), followed by undergraduate (158 persons,40.31%). The working years were more than 5 years(241 persons,61.48%). The majors were mostly pharmaceutics (123 persons,31.38%),followed by pharmacy (including pharmacology )(81 persons, 20.66%). The regular knowledge sources of pharmacists in DTP pharmacy included learning materials (302 person times , 77.04%),textbooks(250 person times ,63.78%)and Wechat push (206 person times ,52.55%);the latest knowledge sources included training courses (347 person times ,88.52%),Wechat push (211 person times ,56.38%)and academic conferences (162 person times ,41.33%). The expected training methods included online video courses (344 person times ,87.76%)and offline courses(248 person times ,63.27%). In terms of prescription checking and dispensing ,there were mainly problems such as incomplete medical documents and materials ;82.91% and 64.54% of pharmacists needed routine medical records and discharge summary,and 91.58% of pharmacists took the doctor ’s handwritten prescription as the basis for dispensing new anti-tumor drugs ; pharmacists paid less attention to allergy history ,genetic history and ADR in the field of drug consultation and guidance. According to DTP pharmacists ,the difficulties in the process of drug treatment management included patient ’s ADR monitoring (239 person times,60.97%),evaluating the rationality of drug use (222 person times ,56.63%),making a complete drug use record (219 person times ,55.87%). The main follow-up visits of pharmacists were telephone (334 person times ,85.20%)and dispensing site (313 person times ,79.85%). And 333 pharmacists(84.95%)thought it was necessary to make an appointment for dispensing ;the score rates of professional knowledge examination of antitumor pharmacy for the respondents were 40.56%-84.69%. In the aspect of pharmaceutical care management ,the main points of deduction were drug evaluation ,content and process of drug treatment management,drug follow-up and record ,and the proportion of deduction was 93%,86% and 64% respectively. In the on-site inspection,it was found that the pharmacist had a single source of working knowledge ,did not fully grasp the contents of the evaluation forms such as ADR classification standard ,and prescription checking did not meet the requirements. CONCLUSIONS : DTP pharmacy in China develops rapidly under the guidance of relevant policies ,but its pharmaceutical care is still in the basic stage,which is far behind the requirements of providing whole-course pharmaceutical care for patients. It is necessary to improve the professional service ability of DTP pharma

ABSTRACT

Objective To analyze the changes of bone strength and body composition in pre- and postmenopausal Dongxiang women and explore the impact of body composition change on bone strength. Methods From Sep. 2016 to Jul. 2018, 203 cases Dongxiang 41-50 year old women (102 cases of premenopause and 101 cases of postmenopause) of Gansu Province were selected by stratified random sampling method, whose bone strength and body composition indexes were measured by ultrasonic bone mineral density meter and body composition analyzer respectively. Results There were lower bone strength and muscle tissue composition in the postmenopausal Dongxiang women (P< 0.05), and there was higher fat tissue composition (P < 0.01). The prevalence of osteoporosis was higher in postmenopausal women (P < 0. 01). Pearson correlation analysis showed that muscle tissue composition was positively correlated with the bone strength (P<0. 01), and it was negatively correlated with fat tissue composition in the pre- and postmenopausal Dongxiang women (P < 0. 0 1). Multivariate linear stepwise regression analysis showed that limb muscle mass and subcutaneous fat mass were a protective factor and a risk factor for bone strength in pre- and post-menopausal Dongxiang women, respectively. Conclusion The bone strength of Dongxiang women was determined by muscle and fat tissue, and associated with the distribution of body composition. The relationship between bone strength and body composition was not affected by menopause. Menopause was an important factor that increased the incidence of osteoporosis in Dongxiang women, and we should reinforce osteoporosis prevention in postmenopausal Dongxiang women. Strengthen physical exercise, increase limb muscle mass and reduce subcutaneous fat could contribute to increase bone strength and prevent osteoporosis in in the pre- and post-menopausal Dongxiang women.

ABSTRACT

We reported a case diagnosed with meningeal cysts complicated with tethered cord syndrome based on prenatal ultrasound images at 37+5 gestational weeks, which also showed horseshoe kidney and intrahepatic vascular abnormalities (arteriovenous fistula) in the fetus. The gravida had a precipitate delivery at 39+4 gestational weeks. The anus of this newborn was about 1 cm in front of the normal position. Intrahepatic arteriovenous fistula and horseshoe kidney were detected by neonatal ultrasound and CT scan, and spinal cystic occupying lesion was found by lumbar-sacrum MRI. Intraspinal tumors were removed through spinal canal exploration and spinal cord tumor resection and were confirmed as ependymal cysts by pathological analysis, which was consistent with the prenatal diagnosis. Postoperative changes of lumbar spine was reported by CT scan after the operation. The baby received successful anoplasty when five months old and no abnormal growth or development were found when followed up to one year and eight months old. Raising awareness of tethered cord syndrome can help reduce missed diagnosis and misdiagnosis.

ABSTRACT

Traditional Chinese medicine (TCM) is an important part of the treatment of primary liver cancer (PLC) in China; however, the current instructions for the integrative use of traditional Chinese and Western medicine for PLC are mostly based on expert opinion. There is no evidence-based guideline for clinical practice in this field. Therefore, the Shanghai Association of Chinese Integrative Medicine has established a multidisciplinary working group to develop this guideline, which focuses on the most important questions about the use of TCM during PLC treatment. This guideline was developed following the methodological process recommended by the World Health Organization Handbook for Guideline Development. Two rounds of questionnaire survey were performed to identify clinical questions; published evidence was searched; the Grading of Recommendations Assessment, Development and Evaluation approach was used to evaluate the body of evidence; and recommendations were formulated by combining the quality of evidence, patient preferences and values, and other risk factors. The guideline was written based on the Reporting Items for Practice Guidelines in Healthcare tool. This guideline contains 10 recommendations related to 8 questions, including recommendations for early treatment by TCM after surgery, TCM combined with transcatheter arterial chemoembolization for advanced PLC, TCM drugs for external use, and acupuncture and moxibustion therapy.

ABSTRACT

<p><b>Background</b>Acute coronary syndrome (ACS) is closely related to unstable plaques and secondary thrombosis. The inflammatory cells in plaques and their inflammatory products may be the cause for plaque instability and ruptures. The study aimed to disclose the changes of inflammatory factors including serum intracellular adhesion molecule-1 (ICAM-1), chitinase-3-like protein 1 (YKL-40), and lipoprotein-associated phospholipase A2 (Lp-PLA2) in patients with ACS and its clinical significance.</p><p><b>Methods</b>A total of 120 patients with coronary heart disease (CHD) were categorized into 2 groups: 69 with ACS and 51 with stable angina pectoris (SAP); 20 patients with chest pain and normal angiography served as a control group. The 120 patients with CHD were categorized into single-vessel disease group, double-vessel disease group, and three-vessel disease group based on the number of coronary artery stenosis. The severity of coronary artery stenosis was quantified based on coronary angiography using Gensini score. They were further divided into mild CHD group with its Gensini score <26 (n = 36), moderate CHD group with its Gensini score being 26-54 (n = 48) and severe CHD group with its Gensini score >54 (n = 36). Serum levels of ICAM-1, YKL-40, and Lp-PLA2 of different groups were determined by enzyme-linked immunosorbent assay. Correlation between ICAM-1, YKL-40, Lp-PLA2, and Gensini score was analyzed.</p><p><b>Results</b>The levels of serum inflammatory factors ICAM-1, YKL-40, and Lp-PLA2 were significantly higher in the ACS group than those in control group and SAP group (all P < 0.05); and compared with control group, no significant difference was observed in terms of the serum ICAM-1, YKL-40, and Lp-PLA2 levels in the SAP group (P > 0.05).The levels of serum ICAM-1, YKL-40, and Lp-PLA2 were not significantly different among control group, single-vessel disease group, double-vessel disease group, and three-vessel disease group (all P > 0.05). The levels of serum ICAM-1, YKL-40, and Lp-PLA2 were not significantly different among control group, mild CHD group (Gensini score <26), moderate CHD group (Gensini score 26-54), and severe CHD group (Gensini score >54) (all P > 0.05). Nonparametric Spearman correlation analysis showed that the levels of serum ICAM-1, YKL-40, and Lp-PLA2 were not correlated with the Gensini score in CHD patients (r = 0.093, r = -0.149, and r = -0.085, all P > 0.05; respectively).</p><p><b>Conclusions</b>The serum levels of ICAM-1, YKL-40, and Lp-PLA2 were correlated with different clinical types of CHD, but not well correlated the severity and extent of artery stenosis, suggesting that ICAM-1, YKL-40, and Lp-PLA2 might be involved in occurrence of instability of atherosclerotic plaque, and might reflect the severity of CHD mostly through reflecting the plaque stability.</p>

ABSTRACT

Objective The mechanisms of docosahexaenoic acid (DHA) protecting the cardiovascular system have not yet been clarified. This study was to investigate the vasorelaxative effect of 13,14-epoxy docosapentaenoic acid (13,14-EpDPE) on coronary arterioles in normal rats and its action mechanisms.Methods We isolated coronary artery smooth muscle cells (CASMCs) from normal rats by enzyme digestion, examined the open probabilities of the large conductance calcium-activated potassium (BK) channels in inside-out single channel configuration in the presence of different concentrations (0, 1, 10 and 100 pmol/L) of 13,14-EpDPE, and recorded the BK currents with the patch clamp in whole cell configuration. Then we assessed the coronary arterial relaxation by measuring dilatory responses to 13,14-EpDPE in pre-contracted tissues with or without pre-treatment with iberiotoxin.Results In the presence of 0, 1, 10 and 100 pmol/L of 13,14-EpDPE, the open probabilities of the BK channels were 0.25±0.03, 0.34±0.03, 0.44±0.06 and 0.85±0.16 (n=6), respectively, significantly increased at 100 pmol/L as compared with 0, 1 and 10 pmol/L (P<0.05). The BK channels were activated by 13,14-EpDP in a concentration-dependent manner and its half-effect concentration was (15.94±1.21) pmol/L. The current density was increased from (58.27±16.35) to (95.94±23.00) pA/pF (P=0.002) after 10 pmol/L 13,14-EpDP perfusion when the stimulation voltage was 100 mV. 13,14-EpDPE dilated the isolated coronary arterioles in a dose-dependent manner, and its effects were abolished after pre-treatment with iberiotoxin (100 nM).Conclusion 13,14-EpDPE can dilate coronary arterioles by activating BK channels in CASMCs, which might be one of the mechanisms underlying its protective effect on the cardiovascular system.

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the effect of oridonin on the human acute lymphocytic leukemia cell line Jurkat and its mechanism.</p><p><b>METHODS</b>Jurkat cells were cultured in vitro and treated with various concentrations (0, 1.25, 2.5, 5, and 10 μmol/L) of oridonin for different lengths of time (24, 48, and 72 hours). The proliferation of Jurkat cells was analyzed by MTT assay. The changes in nuclear morphology were evaluated by fluorescence microscopy at 12 hours after treatment with various concentrations of oridonin. The expression levels of Brg1, P53, and C-myc were determined by semi-quantitative Western blot in Jurkat cells treated with various concentrations of oridonin for 24 hours or 5 μmol/L oridonin for various lengths of time (0, 2, 6, 12, and 24 hours). The expression levels of P53 and C-myc and proliferation of Jurkat cells were evaluated after Brg1 expression was knocked down by Brg1-specific siRNA.</p><p><b>RESULTS</b>Compared with the control group, the proliferation of oridonin-treated Jurkat cells was significantly inhibited in a concentration- and time-dependent manner (P<0.05). According to the florescence microscopic analysis, oridonin treatment led to nuclear pyknosis in Jurkat cells. Compared with the control group, Jurkat cells treated with 5 μmol/L oridonin had reduced expression of Brg1 and C-myc but elevated expression of P53. Brg1 knock-down led to a significant reduction in proliferation of Jurkat cells (P<0.05), up-regulated expression of P53, and down-regulated expression of C-myc.</p><p><b>CONCLUSIONS</b>Oridonin can inhibit the proliferation of Jurkat cells, probably via the Brg1 signaling pathway.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To study the efficacy and safety of Shuanghuang Shengbai Granule (, SSG), a traditional Chinese herbal medicine, on myelosuppression of cancer patients caused by chemotherapy.</p><p><b>METHODS</b>A total of 330 patients were randomly assigned to the treatment group (220 cases, analysed 209 cases) and the control group (110 cases, analysed 102 cases) with a 2:1 ratio by envelope method. The patients in the treatment group at the first day of chemotherapy started to take SSG for 14 days, while the patients in the control group took Leucogon Tablets. The changes of the blood routine, clinical symptoms and immune function in both groups were observed for safety and efficacy evaluation.</p><p><b>RESULTS</b>At the 7th day of chemotherapy, the white blood cells (WBCs) level in the treatment group was significantly higher than that in the control group (P<0.05). After treatment, the WBCs rate in the normal range accounted for 50.2% in the treatment group, the myelosuppression of WBCs and neutrophil were mainly grade I, while 8.1% and 5.7% of patients emerged grade III and grade IV myelosuppression, respectively. The incidence of myelosuppression of the treatment group was significantly lower than that of the control group (P<0.05). The total effective rate of Chinese medicine syndrome in the treatment group was significantly higher than that in the control group (84.2% vs. 72.5%, P<0.05). The immune cell levels in both groups were maintained in the normal range. Compared with that before treatment, the levels of CD3and CD4cells were significantly increased in the treatment group after treatment (P<0.05). The discrepancy of CD3and CD4cell activity before and after treatment in both groups were significantly different (P<0.05). No obvious adverse event occurred in both groups.</p><p><b>CONCLUSION</b>SSG had a protection effect on bone marrow suppression, and alleviated the clinical symptoms together with clinical safety.</p>

ABSTRACT

Objective To explore the imaging characteristics and diagnostic value of 18 F-FDG PET/CT in patients with hepatic epithelioid hemangioendothelioma ( HEH) . Methods From January 2014 to December 2015, 5 HEH patients (2 males, 3 females; average age (49.2±13.7) years) confirmed by pathology and underwent 18 F-FDG PET/CT imaging were enrolled in this retrospective study. The character-istics of PET/CT images were analyzed. Two-sample t test and Pearson linear correlation analysis were used for data analysis. Results A total of 26 lesions were detected in 4 patients with multiple lesions, of which 88.5%( 23/26) distributed at the liver edge, and 42. 3%( 11/26) had hepatic capsule retraction sign. SUVmax of the 26 lesions was 5.1±2.6 and it was not correlated with tumor size (r=0.054, P>0.05). Lesion FDG uptake in patients with distant metastases was higher than that in patients without distant metastases (6.08±1.80 vs 3.84±1.14;t=4.15, P<0.05). Two patients underwent the delayed imaging, and FDG up-take in 11/14 lesions was higher compared with that of early imaging, and 3/14 lesions were newly detected by the delayed imaging. One patient had diffuse low-density lesions with diameters between 6.1 and 35.5 mm and SUVmax between 2.6 and 8.1. Conclusion Liver lesions of HEH patients show some features on 18F-FDG PET/CT images which can find distant metastases, and the delayed imaging can improve the detection rate of lesions.

ABSTRACT

Near infrared spectroscopy (NIR) was used to detect trans fatty acids (TFA) in edible vegetable oils quantitatively. And prediction model of TFA was optimized through band selection, pretreatment method, variable selection and modeling method. NIR spectra of 98 edible vegetable oil samples were collected in spectral range of 4000-10000 cm-1 using an Antaris Ⅱ Fourier transform near infrared spectrometer, and the true content of TFA was measured by gas chromatography. First, optimization of waveband and pretreatment method was conducted on original spectra. On this basis, competitive adaptive reweighted sampling (CARS) was used to select important variables that related to TFA. Finally, the prediction models of TFA content in edible vegetable oils were established using principal component regression ( PCR), partial least square (PLS) and least square support vector machine (LS-SVM). The results indicated that NIR spectroscopy was feasible for detecting TFA content in edible vegetable oils, R2 of the best prediction model after optimized in calibration and prediction sets were 0. 992 and 0. 989, and root mean square error of calibration (RMSEC) and root mean square error of prediction ( RMSEP) were 0. 071% and 0. 075% , respectively. Only 26 variables were used in the best prediction model, accounting for 0. 854% of the whole waveband variables. In addition, compared with the full waveband PLS prediction model, the R2 in prediction set increased from 0. 904 to 0. 989, and RMSEP decreased from 0. 230% to 0. 075% . It shows that model optimization is very necessary, CARS method can select important variables related to TFA effectively and immensely reduce the number of modeling variables, so it can simplify the prediction model, and greatly improve the accuracy and stability of prediction model.
