Objective To explore the roles of different insulin resistance indexes[triglyceride-glucose (TyG),triglyceride (TG)/high-density lipoprotein cholesterol (HDL-C),and metabolic score for insulin resistance (METS-IR)]and combinations of two indexes in predicting diabetes risk in hypertensive population. Methods The survey of hypertension was conducted for the residents in Wuyuan county,Jiangxi province from March to August in 2018.The basic information of hypertensive residents was collected by interview.Blood was drawn on an empty stomach in the morning and physical measurements were carried out.Logistic regression model was employed to analyze the relationship between different insulin resistance indexes and diabetes,and the area under the receiver operating characteristic curve was used for evaluating the predictive effects of each index on diabetes risk. Results A total of 14 222 hypertensive patients with an average age of (63.8±9.4) years old were included in this study,including 2616 diabetic patients.The diabetic hypertensive population had higher TyG (t=50.323,P<0.001),TG/HDL-C (Z=17.325,P<0.001),and METS-IR (t=28.839,P<0.001) than the non-diabetic hypertensive population.Multivariate analysis showed that each insulin resistance index was positively correlated with diabetes risk.The area under curve of each insulin index was in a descending order of TyG (0.770)> METS-IR (0.673)> TG/HDL-C (0.620).The difference in the area under curve between two indexes was statistically significant[TyG vs.TG/HDL-C (Z=42.325,P<0.001);TyG vs.METS-IR(Z=17.517,P<0.001);METS-IR vs.TG/HDL-C (Z=10.502,P<0.001)]. Conclusions Elevated insulin resistance indexes can increase the risk of diabetes.TyG and the combination of indexes outperform TG/HDL-C and METS-IR in the prediction of diabetes.

Abstract@#The onset and progression of puberty development is affected by interaction of genes and environments, and is linked to lifelong health. A comprehensive understanding of pubertal development in Chinese children and its influence on health outcomes becomes an important public health concern. Therefore, building an evaluation index system for Chinese children to assess the puberty onset and the temporal sequences throughout the puberty stage, and establishing a multidimensional predictive model for puberty trajectory lay down the foundation for this issue. This article reviews the currently available evidence referring to the assessment system and the prediction model for puberty timing, and outlines directions for future research in this area.

Abstract Purpose: To investigate the impact of different hypoxia reoxygenation (HR) times on autophagy of rat cardiomyocytes (H9C2). Methods: Rat cardiomyocytes were randomly divided into normal control group (group A), hypoxia group (group B), 2 h HR group (group C), 12 h HR group (group D), and 24 h HR group (group E). LC3 II/LC3 I was determined via western blotting, and cell viabilities of cardiomyocytes were measured using methyl thiazolyl tetrazolium (MTT) assay. Results: Cell viabilities in HR model groups were significantly lower than those of group A (P<0.05). LC3 II/LC3 I levels in groups B to D were significantly higher than those of group A (P<0.05), and group D showed the highest LC3 II/LC3 I levels. Cell viabilities in groups B to D were significantly lower than those of group A (P<0.05), with group D showing the lowest cell viabilities (P<0.05). Conclusions: Hypoxia can induce autophagy in rat cardiomyocytes, which can be further activated by reoxygenation; most notable after 12 h. Hypoxia-induced cell injury can be aggravated by reoxygenation. The lowest cell viability was observed at 12 h after reoxygenation; however, cell viability can be recovered after 24 h.

Erectile dysfunction (ED) associated with type 2 diabetes is a severe problem that requires effective treatment. Pancreatic kininogenase (PK) has the potential to improve the erectile function of ED patients. This study aims to investigate the effect of PK on erectile function in streptozotocin-induced type 2 diabetic ED rats. To achieve this goal, we divided male Sprague-Dawley rats into five groups. One group was not treated, and the other four groups were treated with saline, sildenafil, PK or sildenafil, and PK, respectively, for 4 weeks after the induction of type 2 diabetic ED. Then, intracavernous pressure under cavernous nerve stimulation was measured, and penile tissue was collected for further study. Endothelial nitric oxide synthase levels, smooth muscle content, endothelium content, cyclic guanosine monophosphate (cGMP) levels in the corpus cavernosum, and neuronal nitric oxide synthase levels in the dorsal penile nerve were measured. Improved erectile function and endothelium and smooth muscle content in the corpus cavernosum were observed in diabetic ED rats. When treating diabetic ED rats with PK and sildenafil at the same time, a better therapeutic effect was achieved. These data demonstrate that intraperitoneal injection of PK can improve erectile function in a rat model of type 2 diabetic ED. With further research on specific mechanisms of erectile function improvement, PK may become a novel treatment for diabetic ED.

Objective@#To explore the topological properties of the degree and strength of nodes in the binary and weighted brain white matter networks of the patients with psychogenic erectile dysfunction (pED) and analyze the changes of myelin integrity, number and length of the white matter fibers in the topological space.@*METHODS@#Diffusion tensor imaging data were obtained from 21 patients with pED and 24 healthy controls matched in sex, age, and years of education and subjected to preprocessing. The whole cerebral cortex was divided into 90 regions, followed by fiber tracking, construction of the binary and weighted white matter networks, and calculation of the node degrees and connectivity strengths in different brain regions. The property values were compared between the two groups using the two-sample t-test, the results were corrected by multiple testing correction, and the correlation of the property values with the erectile function of the patients was subjected to Pearson's correlation analysis.@*RESULTS@#Compared with the healthy controls, the pED patients showed significantly decreased node degree of the left triangular part of inferior frontal gyrus (IFG) (7.54±1.44 vs 5.95±1.28, t = -3.88, corrected P = 0.02), medial orbital part of superior frontal gyrus (SFG) (10.08±3.60 vs 6.29±3.30, t = -3.67, corrected P = 0.02), and amygdala (6.50±2.11 vs 4.29±1.31, t = -4.16, corrected P = 0.01) in the binary networks, as well as the connectivity strength of the left triangular part of IFG (2.50±0.68 vs 1.72±0.50, t = -4.35, corrected P = 0.01), medial orbital part of SFG (3.17±0.97 vs 2.08±1.10, t = -3.53, corrected P = 0.03), and amygdala (1.80±0.69 vs 1.11±0.39, t = -4.03, corrected P = 0.01) in the fractional anisotropy (FA) weighted networks. The node degree of the left amygdala was negatively correlated with the total score (r = -0.47,P = 0.04), second item score (r = -0.46, P = 0.03), and third item score of IIEF-5 (r = -0.45, P = 0.04) in the pED patients.@*CONCLUSIONS@#The myelin integrity of the white matter fibers in the left frontal lobe and amygdale is impaired in pED patients, which leads to the aberrant generation, processing and regulation of their emotions. The decreased pivotal role and importance of the white matter fibers connecting the left amygdale may be associated with pED.

Objective To investigate the diagnosis and surgical treatment strategies of intravenous leiomyomatosis(IVL)extending through inferior vena cava into the right cardiac cavities. Methods Thirty patients of IVL extending through inferior vena cava into the right cardiac cavities were treated in Peking Union Medical College Hospital from November 2002 to January 2015.The following variables were studied: age,cardiopulmonary bypass time,deep hypothermic circulatory arrest time,origins of IVL,blood loss,duration of post-operative hospital stay,hospitalization expenses,edema of lower extremity,blood transfusion,postoperative complication,residual IVL,and re-grow or recurrence. Results Thirteen of 30 patients reported double lower limb edema. The cardiopulmonary bypass was applied in 27 cases,and the average duration of cardiopulmonary bypass was(106.9±53.7)min. Then,21 patients were treated with the deep hypothermic circulatory arrest,and the mean time was(28.2±11.6) min. The tumors originated from the genital veins in 9 cases,the iliac vein in 13 cases,and both veins in 8 cases. The average intra-operative blood loss volume was (2060.5±2012.3)ml,and 21 patients received blood transfusion. The average hospitalization time was(18.9±8.3)days and the average hospitalization expenses was (80 840.4±28 264.2)RMB yuan. While 14 patients had postoperative complications,there was no serious postoperative complication or death.All patients have shown a favorable outcome.Conclusions Tumor embolus extending through inferior vena cava into the right cardiac cavities should be suspected in patients with multiple hysteromyoma. Successful therapy for IVL with right cardiac cavities extension is dependent on reasonable surgical treatment strategies. Surgical removal of the ovaries is vital to avoid IVL re-grow or recurrence.

In order to find new tyrosinase inhibitors and antioxidant materials, we investigated 44 plants, which were evaluated for the anti-tyrosinase and antioxidant activities. The mushroom tyrosinase inhibition assay and 2, 2-Diphenyl-1- picrylhydrazyl [DPPH] radical scavenging assay were conducted to evaluate these activities. Among all tested plant extracts, Morus alba L. [positive control], Rhodiola crenulata [Hook. f. et Thorns.] H. Ohba, Momordica charantia L., Cuminum cyminum L. et al exhibit higher tyrosinase inhibition. Rhodiola crenulata [Hook. f. et Thorns.] H. Ohba, Rosa rugosa Thunb. and Eugenia caryophyllata Thunb. perform the highest antioxidant activity, similar to vitamin C [the positive control]. A low positive correlation is found in the DPPH radical scavenging and tyrosinase inhibition assay. Considering these factors, the extracts of Rhodiola crenulata [Hook. f. et Thorns.] H. Ohba, Alpinia officinarum Hance and Zanthoxylum bungeanum Maxim, exhibit high anti-tyrosinase and antioxidant activities and could be used in the cosmetic industry. Further studies are warranted to characterize the compounds responsible for the anti-tyrosinase and antioxidant properties of these plant extracts

Objective:To explore application value of real-time three-dimensional echocardiography (RT-3DE ) for heart function evaluation after percutaneous coronary intervention (PCI) .Methods:Clinical data of 45 patients with coronary heart disease (CHD) collected from Jan 2013 to Jan 2014 in our hospital were enrolled .All patients received selective coro-nary angiography (CAG) and PCI .Another 45 healthy cases undergoing physical examination during the same period were selected as normal control group .End-diastolic volume (EDV) ,end-systolic volume (ESV) ,left ventricular ejection frac-tion (LVEF) ,peak ejection rate (PER) and peak filling rate (PFR) were measured by RT-3DE and two-dimensional echo-cardiography (2DE) respectively and compared between two groups .Results:In normal control group ,there were no sig-nificant differences in all indexes between two measuring methods ,P>0.05 all;in CHD group ,compared with 2DE meas-ured value ,there were significant rise in EDV [ (130.6 ± 30.3) ml vs .(152.5 ± 35.2) ml] ,ESV [ (75.2 ± 21.8) ml vs . (94.1 ± 22.5) ml] ,PER [(2.41 ± 0.47) vs .(2.81 ± 0.39)] and PFR [(1.85 ± 0.25) vs .(2.13 ± 0.31)] ,and significant reduction in LVEF [ (45.8 ± 5.2)% vs .(41.6 ± 4.9)% ] in RT-3DE ,P<0.01 all;on one week ,one month and three months after PCI ,EDV and ESV gradually reduced ,LVEF ,PER and PFR gradually rose in CHD group with significant difference ,P<0.05 or <0.01 .Conclusion:RT-3DE can perform direct ,accurate and quantitative evaluation on heart form and function before and after PCI ,which is a reliable ,fast ,simple and new method evaluating PCI therapeutic effect in CHD patients .
