ABSTRACT

Objective:To explore the features of free uroflow(FF) curve patterns in female patients with detrusor underactivity(DU) and their clinical significance.Methods:Data of 275 adult female patients with lower urinary tract symptoms(LUTS) underwent urodynamic studies(UDS) at urology center of our hospital from June 2014 to June 2016 were analyzed retrospectively. The uroflow curve patterns of patients with DU were classified and analyzed in the context of parameters of FF, cystometry (CM), and pressure-flow study(PFS). The prevalence of each abnormal uroflow curve pattern in DU patients were calculated and compared with those in non-DU patients.Results:No bell-shaped curve was found in 141 patients with DU. The abnormal curve patterns can be divided into 5 types: Type Ⅰ (bell-shaped curve with saw tooth) in 20 cases (14.2%), Type Ⅱ (box-like curve) in 34 cases (24.1%), Type Ⅲ (triangle curve with decreasing slop) in 62 cases(43.9%), Type Ⅳ (triangle curve with increasing slop) in 4 cases (4.3%), Type Ⅴ (tide-wave curve)in 19 cases (13.5%). Maximum flow rate of free uroflow(Q max.FF) of type Ⅰ [(28.4±9.7) ml/s] was significantly greater than that of type Ⅱ, Ⅲ and Ⅴ[(17.0±4.1), (15.8±5.4) and (12.9±6.4) ml/s, P<0.05]. Flow time of free uroflow(FT.FF) of type Ⅲ and Ⅴ [(43.7±17.2) and (50.1±28.9)s] were significantly longer than that of type Ⅰ and Ⅱ [(18.5±7.3)s and (27.2±9.7)s, P<0.05]. Post voided residual > 50ml was noted in 19 cases (30.6%) of type Ⅲ, 7 cases (36.8%) of type Ⅴ, 1 case (2.9%) of type Ⅱ and no one in type Ⅰ and Ⅳ. Abnormal manifestations in cystometry mainly included bladder hypersensitivity, detrusor overactivity, and stress urinary incontinence. Detrusor pressure at Q max (Pdet.Q max) of type Ⅴ [(7.4±5.0) cmH 2O] was significantly lower than that of type Ⅰ, Ⅱ, Ⅲ [(11.8±6.7), (12.0±5.3), (12.1±5.0) cmH 2O, P<0.05]. Among 134 cases of non-DU, there were type Ⅰ curves in 88 cases (65.7%), type Ⅱ curves in 4 cases (2.9%), type Ⅲ curves in 15 cases (11.2%), type Ⅳ curves in 1 cases (0.7%), type Ⅴ curves in 7 cases (5.2%). And normal bell-shaped curves in 19 cases(14.2%). The prevalence of type Ⅱ, Ⅲ and Ⅴ in DU patients was significantly higher than that in the non DU patients ( P<0.05). Conclusions:This study reveals that the characteristics of reduced detrusor contractility and duration, prolonged bladder emptying or incomplete emptying can be reflected in the patterns of free uroflow curve in female patients with DU. The abnormalities of these free uroflow curve patterns, especially type Ⅱ, Ⅲ and Ⅴ will be helpful in preliminarily screening DU in females.

ABSTRACT

Heart failure is a complex clinical syndrome,which is the final result of compensatory failure of heart injury caused by various reasons. Long-term persistent cardiac stress leads to mitochondrial dysfunction,which in turn further damages cardiomyocytes and leads to disease progression. Timely removal of damaged mitochondria in cardiomyocytes and maintaining a good living environment of viable mitochondria is not only an effective means to protect cardiomyocytes,but also a new way to prevent and treat heart failure and ventricular remodeling. Mitochondrial quality control is a series of cellular activities for mitochondria to maintain their structural and functional stability,including oxidative stress response,regulation of mitochondrial dynamics,mitochondrial autophagy,intracellular calcium regulation and so on. Traditional Chinese medicine(TCM) mostly uses drugs of replenishing Qi and activating blood circulation in the treatment of chronic heart failure,and Qi and mitochondria are similar in function. According to TCM,the performance of the body as "static,descending and inhibitory" in the case of Qi deficiency can also be compared with the energy defect of mitochondria. The classical method of tonifying qi and activating blood circulation in TCM can be applied here. In recent years,TCM takes mitochondria as the target and carries out many related experimental studies from the point of view of myocardial energy supply. It is found that Chinese herbs for replenishing Qi and activating blood circulation can participate in regulating the quality control mechanism of intracellular mitochondria with multiple targets and links. It is proved by experiments that Chinese herbs for replenishing Qi and activating blood circulation can exert myocardial protective effect through this mechanism.

ABSTRACT

Objective:To investigate the effect of Elian granule on autophagy and the phosphatidylinositol -3 kinase (PI3K)/protein kinase B (PKB/Akt)/mammalian target of rapamycin (mTOR) signaling pathway in gastric tissue of rats with gastric cancer. Method:SPF SD rats were randomly divided into the normal, model, Elian granule, and Weifuchun groups. In addition to the routine feeding in the normal group, the model, Elian granule, and Weifuchun groups received <italic>N</italic>-methyl-<italic>N</italic>'-nitro-<italic>N</italic>-nitrosoguanidine (MNNG) to induce gastric cancer in rats, and they were respectively given normal saline, Elian granule aqueous solution (3.240 g·kg<sup>-1</sup>) and Weifuchun aqueous solution (0.390 g·kg<sup>-1</sup>) by gavage (<italic>ig</italic>) for 48 weeks. The gross changes of the stomach taken by laparotomy were observed by naked eyes. Hematoxylin-eosin (HE) staining was performed to observe the histopathological changes of the gastric tissue in rats. Real-time quantitative polymerase chain reaction (Real-time PCR) and Western blot (WB) were used to detect the mRNA and protein expression of microtubule-associated protein 1 light chain 3 beta (LC3B), Beclin1, p62, PI3K, Akt, mTOR in rat gastric tissue. Result:Compared with the normal group, the model group showed gastric distension, thinner gastric wall, pale gastric mucosa, atrophied and flat folds, disordered course, and visible nodules and vegetations. Compared with the model group, the Elian granule group demonstrated alleviated gastric distension, dark gastric mucosa, reduced folds, and regular course, with the thinned gastric wall improved and granular nodules observed occasionally. According to HE staining, compared with the normal group, the model group showed crowded and disordered rat gastric glands, diverse in shape, varied cell morphology, basophilic cytoplasm, large irregular hyperchromatic nuclei, visible mitosis, and infiltrated and destroyed muscularis mucosae. While compared with the model group, the arrangement of gastric glands was regular, and a few mildly atypical cells could be observed in rats of the Elian granule group. Compared with the normal group, the model group exhibited decreased expression of LC3B and Beclin1 mRNA and protein in gastric tissue (<italic>P</italic><0.05), and increased expression of PI3K, p62, Akt, and mTOR mRNA and protein (<italic>P</italic><0.05). Compared with the model group, the Elian granule group showed increased expression of LC3B and Beclin1 mRNA and protein in gastric tissue (<italic>P<</italic>0.05), and decreased expression of PI3K mRNA and p62, Akt, and mTOR mRNA and protein (<italic>P</italic><0.05). Conclusion:Elian granule can improve the cell atypia of gastric tissue in rats with gastric cancer, and the mechanism may be related to the inhibition of the PI3K/Akt/mTOR signaling pathway to promote autophagy.

ABSTRACT

Objective:To observe the effects of Chaihu Shugansan on gastric motility and mitochondrial function and mitophagy in rats with functional dyspepsia (FD) and to preliminarily reveal its mechanism in preventing and treating FD. Method:Thirty-two SD rats of SPF grade were randomly divided into the normal group, model group, Chaihu Shugansan (4.8 g·kg<sup>-1</sup>) group, and domperidone group (4.5 mg·kg<sup>-1</sup>) after one week of adaptive feeding, with eight rats in each group. Rats in all groups except for the normal group were exposed to modified tail-clamping stimulation for inducing FD. Four weeks later, the semi-solid nutritive medium was used to observe the gastric emptying rate of FD rats, and the serum citrate synthase (CS), motilin (MTL), and gastrin (GAS) were detected by enzyme-linked immunosorbent assay (ELISA). The pathological changes in gastric tissue were observed by hematoxylin-eosin (HE) staining, the mitochondrial characteristics by transmission electron microscopy, and the expression of microtubule-associated protein light chain 3 (LC3) and voltage-dependent anion-selective channel 1 (VDAC1) by immunofluorescence co-localization. The mitochondria were extracted from fresh gastric tissue for measuring the reactive oxygen species (ROS), malondialdehyde (MDA), and superoxide dismutase (SOD) levels using the biochemical kits. The mitochondrial LC3, yeast Atg6 homologous(Beclin1), and p62 protein expression was assayed by Western blot. Result:Compared with the normal group, the model group exhibited significantly reduced gastric emptying rate (<italic>P</italic><0.01) and serum CS, MTL, and GAS levels (<italic>P</italic><0.01). HE staining showed no pathological changes like erosion or ulcer in the gastric tissue of rats in each group. However, the mitochondria in the gastric tissue were observed swollen and dilated under the transmission electron microscope, and vacuolar lesions appeared. The co-expression of LC3 with VDAC1 increased significantly (<italic>P</italic><0.01). The mitochondrial ROS and MDA levels were elevated significantly (<italic>P</italic><0.01), while SOD content was significantly reduced (<italic>P</italic><0.01). The protein expression levels of LC3 and Beclin1 were significantly up-regulated (<italic>P</italic><0.05, <italic>P</italic><0.01), whereas p62 protein expression was down-regulated significantly (<italic>P</italic><0.01). Compared with the model group, Chaihu Shugansan and domperidone elevated the gastric emptying rate (<italic>P</italic><0.05) and serum CS, MTL, and GAS levels (<italic>P</italic><0.05, <italic>P</italic><0.01). It was observed under the transmission electron microscope that the mitochondrial nuclear membrane of the gastric tissue was intact, with clear structure and high density of mitochondrial cristae, and mitochondrial fission and fusion were observed in some parts. The co-localization area of LC3 and VDAC1 was significantly reduced (<italic>P</italic><0.01). The mitochondrial ROS and MDA levels declined significantly (<italic>P</italic><0.05, <italic>P</italic><0.01), whereas SOD level rose (<italic>P</italic><0.05). The protein expression levels of LC3 and Beclin1 were significantly down-regulated (<italic>P</italic><0.05, <italic>P</italic><0.01), while that of p62 was obviously up-regulated (<italic>P</italic><0.01). Conclusion:The mechanism of Chaihu Shugansan in preventing and treating FD may be related to the improvement of mitochondrial function and the inhibition of mitophagy in gastric tissue.

ABSTRACT

Objective:To explore the effects of mirror therapy on upper limb motor function recovery and corticospinal tract remodeling after stroke. Methods:From March, 2017 to March, 2019, 42 subcortical stroke patients with upper limb dysfunction from Shanghai Fifth People's Hospital were randomly divided into control group (n = 21) and observation group (n = 21). Both groups received routine rehabiliation, while the observation group received mirror therapy additionally, for twelve weeks. They were assessed with Fugl-Meyer Assessment-Upper Extremities (FMA-UE), and scanned with diffusion tensor imaging (DTI) before and after treatment. The fractional anisotropy (FA) in posterior limb of internal capsule (PLIC) was obtained. Results:The scores of FMA-UE improved in both groups after treatment (t > 9.560, P < 0.001), and improved more in the observation group than in the control group (t > 2.634, P < 0.05). FA decreased significantly in the affected-lateral PLIC compared with that in the unaffected-lateral PLIC in both groups (t > 11.368, P < 0.001). FA in the affected side increased significantly after treatment in the observation group (t = 2.385, P < 0.05), while there was no significant difference in the control group (t = -0.596, P > 0.05). FA increased more significantly in the observation group than in the control group (t = 2.306, P < 0.05). Conclusion:Mirror therapy can promote the recovery of motor function of upper limb and the corticospinal tract remodeling in stroke patients.

ABSTRACT

Objective To understand the influence of hot spring bathing intervention on population's antioxidation functions. Methods Three typical types of hot spring(metasilicic acid type, warm mineral type and temperature type)in Guizhou Province were selected for investigation. According to the inclusion-exclusion criteria, questionnaires and physical examinations results, 421 individuals were selected as observation subjects for hot spring bathing intervention, of which 311 subjects completed 40 to 50 minutes of intervention once a day, 5 days a week, and for 4 weeks. Two physical examinations before and after the intervention were conducted for the 311 subjects. The fasting venous blood samples on the mornings of two physical examinations were collected and the serum was separated. Levels of serum oxidative stress-related parameters including total superoxide dismutase(T-SOD), copper zinc superoxide dismutase(Cu-Zn SOD), glutathione sulfur transferases(GSTs)glutathione peroxidase(GSH-px), sulfhydryl(-SH)and malondialdehyde(MDA)were measured by enzymatical methods. Results The overall comparison showed that compared with before the bathing intervention, the levels of antioxidant enzymes including T-SOD, Cu-Zn SOD, GSTs and GSH-px significantly increased in serum after the intervention(all P < 0.05). There was an increasing trend of serum -SH level after the intervention, but with no statistical differences were seen(P > 0.05). MDA, a product of lipid peroxidation, significantly decreased in serum after the intervention(P < 0.05). The results of classified comparison showed that the effects of different hot spring types on antioxidant enzymes were different. Metasilicic acid type significantly increased the activities of GSTs and GSH-px in serum(all P < 0.05), warm mineral type significantly increased the activities of T-SOD and Cu-Zn SOD in serum(all P < 0.05), and temperature type significantly increased the activities of T-SOD, Cu-Zn SOD and GSTs in serum(all P < 0.05). There were increasing trends of serum -SH levels after bathing intervention of all three hot spring types, but no statistical differences were seen(all P > 0.05). The serum MDA levels decreased significantly after bathing intervention of all three types of hot springs(all P < 0.05). Conclusion Overall, bathing intervention of hot springs can improve the activities of antioxidant enzymes and reduce lipid peroxidation products in population. The results of oxidative stress parameters are slightly different in different types of hot springs. The subjects mainly show the elevation of glutathione related enzyme(GSTs and GSH-px)activities after intervention of metasilicic acid type, the elevation of superoxide dismutase(SOD)activities after intervention of warm mineral type and temperature type, and the decline of lipid peroxidation levels after intervention of all three types. It suggests that hot spring bathing may have certain effects on improving the body's antioxidation functions.

ABSTRACT

Objective To study the relieving effects of hot spring bath therapy on sleep quality for people with sleep disorders based on data from health bracelets. Methods After health examinations, 311 people with sleep disorders who participated in the bath therapy in five typical hot spring areas in Guizhou Province were selected as the subjects. A four-week hot spring bath therapy was implemented, and the bathing method and the classification of hot springs were the same as the"Overview of study of the physiotherapy efficacy of typical hot springs in Guizhou Province". The daily sleep time at night(minutes), deep sleep ratio(%), light sleep ratio(%)and rapid eye movement ratio(%)for all subjects were collected using the Huawei Honor Band 3 health bracelets. Repeated measures analysis of variance was used to compare the differences in sleep quality indicators of each group at night each week. The effect of three different hot spring bath therapies on the improvement of night sleep quality was evaluated by factor analysis. Results Hot spring bath therapy can increase night sleep time and deep sleep ratio, while reducing light sleep ratio. Compared with the first week, the night sleep time in the following three weeks significantly increased(P < 0.05), especially in the fourth week; the deep sleep ratio during the third and fourth weeks was significantly higher than during the first and second weeks(P < 0.05), but the light sleep ratio was lower than during the first and second weeks(P < 0.05). The rapid eye movement ratio did not change significantly throughout the 4 weeks(P > 0.05). Further classified according to the physiotherapy components of geological hot springs, the results showed that the water temperature type of hot springs can increase night sleep time and reduce light sleep ratio; the warm mineral type of hot springs has a certain regulatory effect on increasing night sleep time, deep sleep ratio and reducing light sleep ratio; the metasilicic acid type of hot springs can improve night sleep quality by increasing night sleep time and deep sleep ratio, while reducing light sleep ratio and rapid eye movement ratio. The factor analysis results suggest that the metasilicic acid type of hot springs is better than the water temperature type and warm mineral type of hot springs in improving night sleep quality. Conclusion Hot spring bath therapy can improve the night sleep quality for people with sleep disorders to varying degrees, and the metasilicic acid type of hot springs is relatively better than other types.

ABSTRACT

Objective To investigate the effects of hot spring baths on blood pressure, resting heart rate, cardiovascular function related indicators and physical signs in population with high-normal blood pressure. Methods Residents of typical hot spring areas in Guizhou Province were included as the subjects. According to the epidemiological survey of the research group and the physical examination results before the intervention, combined with the inclusion and exclusion criteria, a total of 217 people with high normal blood pressure were selected as the observation subjects. The intervention of hot spring baths was carried out for four weeks, once time per day, 5 times per week, for 40-50 minutes each time. After the intervention, the blood pressure, resting heart rate and serum levels of creatine kinase(CK), lactate dehydrogenase(LDH), and α-hydroxybutyrate dehydrogenase(α-HBDH)were detected, and the improvement of cardiovascular related signs(palpitation, dizziness/headache, cough/sputum and night sweats)were clinically examined. SPSS 23.0 software was used for statistical analysis. Results Paired t-test results showed that the systolic blood pressure, diastolic blood pressure and resting heart rate of 217 high normal blood pressure subjects were significantly lower after hot spring baths(P < 0.01). Further analysis revealed that the number of people with high normal blood pressure dropped from 217 to 128 after the hot spring baths. Before the intervention, 95 of the 217 people with high-normal blood pressure had resting heart rates between 80 and 90 beats/min, and 35 of them above 90 beats/min. After the intervention, the resting heart rates of those above people decreased to 68 and 14, respectively. Serum levels of cardiovascular related indicators showed that CK, LDH, and α-HBDH levels in people with high-normal blood pressure decreased to some extent after the intervention, and CK level was significantly lower than that before the intervention(P < 0.05). The results of clinical examination showed that hot spring baths had a significant improvement effect on palpitation, dizziness/headache, cough/expectoration, and night sweats in people with high-normal blood pressure. Conclusion The typical hot spring baths in Guizhou Province can reduce the blood pressure and resting heart rate in population with high-normal blood pressure, and improve the cardiovascular function related indicators and physical signs to a certain extent.

ABSTRACT

OBJECTIVE: To observe the effect of moxibustion on cardiac function and expression of myocardial tumor suppressor protein p53, mammalian target of rapamycin (mTOR) and phosphorylated(p)-mTOR (excessive autophagy-associated proteins of cardiomyocytes) in rats with chronic heart failure (CHF), so as to explore its mechanisms underlying improvement of CHF. METHODS: SD rats were divided into blank control (n=11), model(n=8), autophagy activator (n=8), autophagy inhibitor (n=9) and moxibustion(n=9) groups. The CHF model was established by i.p. injection of Doxorubicin Hydrochloride (DOX, 1 mg/mL, 1-4 mg/kg) every other day. Moxibustion was applied to bilateral "Feishu" (BL13) and "Xinshu" (BL15) for 20 min, 5 times a week for 3 weeks. Rats of the autophagy activator group received gavage of Rapamycin (RAPA, 2 mg/kg) and those of the autophagy inhibitor group received i.p. injection of Methyladenine (3-MA, 15 mg/kg) 5 times a week for 3 weeks after successful modeling. The heart weight and body weight were measured to calculate heart mass index (HW/BW=heart weight ÷ body weight). Cardiac output (CO) and heart rate (HR) were measured by using a cardiac function meter. Serum N-terminal pro-brain natriuretic peptide (NT-pro BNP) content was assayed by using ELISA, and the expression of myocardial p53, p-mTOR and mTOR proteins was examined by Western blot. RESULTS: (1) Compared with the blank control group, the HR, HW/BW, NT-pro BNP content and p53 expression levels were significantly increased (P<0.01), and the CO and ratio of p-mTOR/mTOR were significantly decreased in the model group (P<0.01). (2) Compared with the model group, the HR, HW/BW and NT-pro BNP content of the autophagy inhibitor and moxibustion groups were significantly decreased (P<0.01, P<0.05), and CO and p-mTOR/mTOR ratio were significantly increased in both autophagy inhibitor and moxibustion groups (P<0.01). (3) Compared with the autophagy activator group, the levels of HR, HW/BW, NT-pro BNP and p53 in the autophagy inhibitor and moxibustion groups were significantly lower (P<0.01), and those of CO and p-mTOR/mTOR levels were significantly higher (P<0.01). CONCLUSION: Moxibustion, similar to the autophagy inhibitor, has a protective action on myocardium in CHF rats, which is possible by preventing over expression of myocardial autophagy-associated proteins during CHF.

' acupuncture and moxibustion physicians have a lot of talented people. Their academic theories promote the development of moxibustion theory. - used acupuncture and moxibustion together in clinic, and emphasized reinforcing and reducing method. Moxibustion was performed with unique matching acupoint according to different cases. proposed the theory "moxibustion can cure sores, and has reinforcing and reducing method"scars block the movement of and do not use moxibustion when there is no disease". - elaborated on the theory of moxibustion, which involved a wide range of ideas and advocated the idea of combining acupuncture with drugs. put forward the theory "moxibustion is mostly used at acupoints on the back, and can cure multiple syndromes" "focus on the use of miraculous acupoints for the treatment of emergency diseases" "moxibustion must be treated with enough moxibustion to cure the disease". - thonght that only by carefully identifying the types of diseases and using corresponding acupoints could have a very good curative effect; moxibustion had indications and contraindications, so be careful when used it; moxibustion was divided into and , also divided into reinforcing and reducing methods; sores were suitable for moxibustion and heat syndrome could also be used by moxibustion. He also believed that moxibustion was as important as acupuncture with the complementary relationship. Hence, the valuable significance of moxibustion in clinical practice is explored through the collection of the academic thoughts of -, , -, and -.

ABSTRACT

To characterize the structure and function of ribosomal protein S13 (RPS13), we identified fulllength open reading frames (ORFs) of three RPS13 genes (RPS13-1, RPS13-2, and RPS13-3) of the Chinese medicinal plant, Sophora flavescens. The target genes were amplified by reverse transcription-olymerase chain reaction (RT-PCR), ligated into the pET22b(+) vector, and then transformed into Escherichia coli BL21 competent cells for protein expression. The physicochemical properties, protein motif, evolution, and structural organization of the three RPS13 genes were analyzed using bioinformatics tools. The full-length ORFs (453 bp) of the three RPS13 genes of S. flavescens were cloned, and each encodes a protein of 151 amino acids in length, and their expression was detected by Western blotting. Bioinformatics analysis showed that RPS13s are stable proteins that are closely related to the 40S RPS13s of Vigna radiate var. radiate. Their three-dimensional structures included three -helices at the C-terminal and four -helices at the N-terminal, and the two clusters of helices were connected by a long random coil, which may help maintain the dynamic bridging interactions between the large and small subunits of the ribosome. The full-length ORFs of three RPS13 genes of S. flavescens were successfully cloned and expressed in vitro. The study of the physicochemical properties, evolution, and secondary and three-dimensional structures of the three proteins will provide the theoretical basis for further studies on the function of RPS13s in plants.


Objetivo: Para caracterizar a estrutura e a função da proteína ribossomal S13 (RPS13), identificamos fases de leitura abertas (ORFs) completas de três genes RPS13 (RPS13-1, RPS13-2 e RPS13-3) da planta medicinal chinesa, Sophora flavescens. Métodos: Os genes alvo foram amplificados por reação em cadeia da polimerase por transcrição reversa (RT-PCR), ligados ao vetor pET22b(+), e então transformados em células competentes de Escherichia coli BL21 para expressão protéica. As propriedades físico-químicas, o motivo protéico, a evolução e a organização estrutural dos três genes RPS13 foram analisados utilizando ferramentas de bioinformática. Resultados: ORFs completos (453 pb) dos três genes RPS13 de S. flavescens foram clonados, e cada um codifica uma proteína de 151 aminoácidos de comprimento, e sua expressão foi detectada por western blotting. A análise de bioinformática mostrou que as RPS13s são proteínas estáveis que estão intimamente relacionadas com as 40S RPS13s de Vigna radiata var. radiate. Suas estruturas tridimensionais incluíam três -hélices no C-terminal e quatro -hélices no N-terminal, e os dois aglomerados de hélices eram conectados por uma longa bobina aleatória, o que pode ajudar a manter as interações de ponte dinâmicas entre o subunidades grandes e pequenas do ribossomo. Conclusões: As ORFs completas de três genes RPS13 de S. flavescens foram clonadas e expressas com sucesso in vitro. O estudo das propriedades físico-químicas, evolução e estruturas secundárias e tridimensionais das três proteínas fornecerão a base teórica para estudos adicionais sobre a função das RPS13s em plantas.

ABSTRACT

OBJECTIVE: To noninvasively assess the neurodegenerative changes in the brain of patients with Niemann-Pick type C (NPC) disease by measuring the lesion tissue with the iterative decomposition of water and fat with echo asymmetry and least square estimation-iron quantification (IDEAL-IQ). MATERIALS AND METHODS: Routine brain MRI, IDEAL-IQ and 1H-proton magnetic resonance spectroscopy (1H-MRS, served as control) were performed on 12 patients with type C Niemann-Pick disease (4 males and 8 females; age range, 15–61 years; mean age, 36 years) and 20 healthy subjects (10 males and 10 females; age range, 20–65 years; mean age, 38 years). The regions with lesion and the normal appearing regions (NARs) of patients were measured and analyzed based on the fat/water signal intensity on IDEAL-IQ and the lipid peak on 1H-MRS. RESULTS: Niemann-Pick type C patients showed a higher fat/water signal intensity ratio with IDEAL-IQ on T2 hyperintensity lesions and NARs (3.7–4.9%, p < 0.05 and 1.8–3.0%, p < 0.05, respectively), as compared to healthy controls (HCs) (1.2–2.3%). After treatment, the fat/water signal intensity ratio decreased (2.2–3.4%), but remained higher than in the HCs (p < 0.05). The results of the 1H-MRS measurements showed increased lipid peaks in the same lesion regions, and the micro-lipid storage disorder of NARs in NPC patients was detectable by IDEAL-IQ instead of 1H-MRS. CONCLUSION: The findings of this study suggested that IDEAL-IQ may be useful as a noninvasive and objective method in the evaluation of patients with NPC; additionally, IDEAL-IQ can be used to quantitatively measure the brain parenchymal adipose content and monitor patient follow-up after treatment of NPC.

ABSTRACT

Purpose To investigate the effect of EPCR on the proliferation and migration, and to explore the molecular mechanism of EPCR affecting the tumor growth and metastasis in human breast cancer cell line MCF-7. Methods MCF-7 cell was transfected with EPCR siRNA and treated with anti-PAR-1 antibody. Then CCK-8 assay was performed to determine the proliferation of MCF-7 cell. Transwell migration assay was employed to determine the cell's migration. Cell-ELISA was used to detect the activation of PAR-1 on the membranes of MCF-7. Result After EPCR siRNA transfection, the proliferation and migration ability of the MCF-7 in the interference of EPCR gene group was significantly decreased compared with the negative control and untreated control group. After treated with anti-PAR-1 antibody, the proliferation and migration of ability of MCF-7 were decreased significantly compared with the negative control group and the untreated control group. Cell-ELISA assay indicated that the activation of PAR-1 in the cells surface of MCF-7 cell in the EPCR gene interference group was mitigated versus the negative control and untreated control group. Conclusion EPCR may promote the proliferation and migration of MCF-7 cell by activating PAR-1.

ABSTRACT

<p><b>Background</b>Currently available evaluation criteria for penile tumescence and rigidity have been fraught with controversy. In this study, we sought to establish normative Chinese evaluation criteria for penile tumescence and rigidity by utilizing audiovisual sexual stimulation and RigiScan™ test (AVSS-Rigiscan test) with the administration of phosphodiesterase-5 inhibitor.</p><p><b>Methods</b>A total of 1169 patients (aged 18-67 years) complained of erectile dysfunction (ED) underwent AVSS-RigiScan test with the administration of phosphodiesterase-5 inhibitor. A total of 1078 patients whose final etiological diagnosis was accurate by means of history, endocrine, vascular, and neurological diagnosis, International Index of Erectile Function 5 questionnaire, and erection hardness score were included in the research. Logistic regression model and receiver operating characteristic curve analysis were performed to determine the cutoff value of the RigiScan™ data. Then, the multivariable logistic analysis was used in the selected variables.</p><p><b>Results</b>A normal result is defined as one erection with basal rigidity over 60% sustained for at least 8.75 min, average event rigidity of tip at least 43.5% and base at least 50.5%, average maximum rigidity of tip at least 62.5% and base at least 67.5%, △tumescence (increase of tumescence or maximum-minimum tumescence) of tip at least 1.75 cm and base at least 1.95 cm, total tumescence time at least 29.75 min, and times of total tumescence at least once. Most importantly, basal rigidity over 60% sustained for at least 8.75 min, average event rigidity of tip at least 43.5%, and base at least 50.5% would be the new normative Chinese evaluation criteria for penile tumescence and rigidity. By multivariable logistic regression analysis, six significant RigiScan™ parameters including times of total tumescence, duration of erectile episodes over 60%, average event rigidity of tip, △tumescence of tip, average event rigidity of base, and △tumescence of base contribute to the risk model of ED. In logistic regression equation, predict value P < 0.303 was considered as psychogenic ED. The sensitivity and specificity of the AVSS-RigiScan test with the administration of phosphodiesterase-5 inhibitor in discriminating psychogenic from organic ED was 87.7% and 93.4%, respectively.</p><p><b>Conclusions</b>This study suggests that AVSS-RigiScan test with oral phosphodiesterase-5 inhibitors can objectively assess penile tumescence and rigidity and seems to be a better modality in differentiating psychogenic from organic ED. However, due to the limited sample size, bias cannot be totally excluded.</p>
