Abstract
Objective: To examine the association between objective sleepiness and neurocognitive function before and after continuous positive airway pressure (CPAP) in obstructive sleep apnea (OSA) patients. Methods: A total of 53 patients with overnight polysomnography (PSG) determined moderate-to-severe OSA (apnea hypopnea index (AHI) ≥15 events/h) and with overnight CPAP therapy from West China Hospital, Sichuan University within the period from Feb 2018 to Dec 2018 were enrolled in the study. At the baseline, all patients underwent overnight PSG study, multiple sleep latency test (MSLT), psychomotor vigilance test (PVT), and Epworth sleepiness score (ESS). After CPAP therapy, all patients underwent MSLT and PVT. Paired nonparametric test or t test were used to compare the differences between daytime sleepiness and PVT performance before and after CPAP. Results: Compared with baseline data, AHI [68.8(42.2, 80.0) vs 7.4(3.1, 11.1) events/h, P<0.05] decreased, the percentages of non-rapid eye movement stage 3 sleep time [0(0, 0.5%) vs 4.4%(1.9%, 11.3%), P<0.05] and the percentages of rapid eye movement sleep time [18.6%(13.2%, 22.7%) vs 25.4%(23.85, 30.3%), P<0.05] increased after CPAP therapy. The reaction time (RT) [353.0(317.5, 429.5) vs 333.6(309.7, 381.4) ms, P<0.05], the slowest 10% RT [602.9(473.2, 841.3) vs 505.5(431.6, 618.8) ms, P<0.05] and the fastest 10% RT [260.8(236.6, 300.6) vs 251.4(233.6, 283.2) ms, P<0.05] shortened, and the lapse [6.0(2.5, 16.5) vs 3.0(1.0, 8.5) events, P<0.05] decreased. The mean sleep latency (MSL) [5.8 (3.4, 8.3) vs 7.5(4.7, 12.4) min, P<0.05] increased. The changes in PVT parameters [ΔRT (r=0.20, P>0.05), Δslowest 10% RT (r=0.15, P>0.05), Δfastest 10% RT (r=0.24, P>0.05), and Δlapse (r=0.15, P>0.05)] were not correlated with the change in MSL. The significant association between the slowest 10% RT and ESS was found in baseline data. Conclusions: The change in MSL is not associated with the change in PVT performance before and after CPAP therapy. MSLT and PVT may be different in nature.

Abstract
Objective: To examine the association between mixed sleep apnea (MA) and treatment-emergent central sleep apnea (TE-CSA). Methods: A total of 256 patients meeting the diagnostic criteria of moderate to severe obstructive sleep apnea (OSA) based on overnight polysomnography (PSG) and receiving continuous positive airway pressure (CPAP) therapy in West China Hospital, Sichuan University during the period from August 2013 to November 2018 were enrolled in the study. Based on the mixed apnea index (MAI) and apnea-hypopnea index (AHI) in the baseline PSG study during non-rapid eye movement (NREM) sleep and rapid eye movement (REM) sleep, the subjects were categorized into three groups of A (MAI=0/h, n=110), B (NREM-MAI≥5/h and REM-MAI<5/h, n=72) and C (REM-MAI≥5/h and NREM-MAI< 5/h, n=74). Sleep and breathing related parameters before and after CPAP therapy among three groups and the difference of TE-CSA incidence were analyzed. Results: The AHI [(44.2(26.8,64.5)/h,66.6(56.0,81.7)/h, 79.8(63.6, 88.3)/h], REM-AHI [50.0(34.7, 64.7)/h, 60.1(49.1, 70.0)/h, 66.3(56.1, 74.6)/h] and NREM-AHI[43.5(25.9, 65.1)/h,67.6(53.7, 82.4)/h,81.3(64.2, 91.5)/h]) were higher in group B and C compared to group A (all P<0.05),while the mean and lowest oxygen saturation [(92.6%±3.5%),(90.8%±3.6%),(87.3%±5.1%) and (70.6%±14.1%), (61.0%±16.0%), (47.9%±17.0%)] were lower in group B and group C compared to group A (all P<0.05). The incidence of TE-CSA after initial CPAP was 7.8% in all patients, and the incidence was significantly higher in group B of 14.1% compared to group C of 4.1% and group A of 2.7% (all P<0.05). Conclusions: TE-CSA is correlated with baseline MA, and baseline MA in NREM sleep can predict the incidence of TE-CSA after initial CPAP.

Network analysis and mechanisms of action of Chinese herb-related natural compounds in lung cancer cells. PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2019; 58:152893. [PMID: 30901663 DOI: 10.1016/j.phymed.2019.152893] [Citation(s) in RCA: 19] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/09/2019] [Revised: 03/09/2019] [Accepted: 03/12/2019] [Indexed: 06/09/2023]
Abstract
BACKGROUND Chinese herbal medicines (CHMs) are a resource of natural compounds (ingredients) and their potential chemical derivatives with anticancer properties, some of which are already in clinical use. Bei-Mu (BM), Jie-Geng (JG), and Mai-Men-Dong-Tang (MMDT) are important CHMs prescribed for patients with lung cancer that have improved the survival rate. HYPOTHESIS/PURPOSE The aim of this study was to systemically investigate the mechanisms of action of these CHM products in lung cancer cells. METHODS We used a network pharmacology approach to study CHM product-related natural compounds and their lung cancer targets. In addition, the underlying anti-lung cancer effects of the natural compounds on apoptosis, cell cycle progression, autophagy, and the expression of related proteins was investigated in vitro. RESULTS Ingredient-lung cancer target network analysis identified 20 natural compounds. Three of these compounds, ursolic acid, 2-(3R)-8,8-dimethyl-3,4-dihydro-2H-pyrano(6,5-f)chromen-3-yl)-5-methoxyphenol, and licochalcone A, inhibited the proliferation of A549 lung cancer cells in a dose-dependent manner. Signal pathway analyses suggested that these three ingredients may target cellular apoptosis, anti-apoptosis, and cell cycle-related proteins. These three ingredients induced apoptosis through the regulation of the expression of apoptotic and anti-apoptotic proteins, including B-cell lymphoma-2 and full-length and cleaved poly(ADP-ribose) polymerase proteins. They also induced cell cycle arrest in S and G2/M phases and autophagy in A549 cells. CONCLUSION The pharmacological mechanisms of ingredients from MMDT on lung cancer may be strongly associated with their modulatory effects on apoptosis, autophagy, cell cycle progression, and cell proliferation.

Abstract
BACKGROUND Chinese herbal medicine (CHM) is a complementary natural medicine that is used widely for the treatment of hepatic diseases. The aim of this study was to investigate the effects of the long-term use of CHM for the treatment of liver diseases, as prescribed by TCM doctors, on overall mortality and hepatic outcomes in patients with HCV. PATIENTS AND METHODS We identified 98788 patients with HCV. Of these, 829 and 829 patients who were users and non-users of CHM, respectively, were matched for age, gender, CCI, and comorbidities prior to CHM treatment. The chi-squared test, Cox proportional hazard model, Kaplan--Meier method, and log-rank test were used for comparisons. RESULTS CHM users had a lower risk of overall mortality than non-users after adjustment for comorbidities by using a multivariate Cox proportional hazard model (p-value < 0.001; HR: 0.12, 95% CI: 0.06-0.26). In addition,the CHM users had a lower risk of liver cirrhosis than non-users after adjustment for comorbidities (p-value = 0.028; HR: 0.29, 95% CI: 0.09-0.88). The 12-year cumulative incidences of overall mortality and liver cirrhosis were lower in the CHM group (p-value < 0.05 for both, log rank test). The CHM co-prescription for Dan-Shen, Bie-Jia, Jia-Wei-Xiao-Yao-San => E-Shu was found to occur most often associated for the specific treatment of HCV infection. CONCLUSION CHM as adjunctive therapy may reduce the overall mortality and the risk of liver cirrhosis in patients with HCV. The comprehensive list of the herbal medicines that may be used for the treatment of patients with HCV may be useful in future scientific investigations or for future therapeutic interventions to prevent negative hepatic outcomes in patients with HCV.

Abstract
Hip fracture is a major public health concern, with high incidence rates in the elderly worldwide. Hip fractures are associated with increased medical costs, patient dependency on families, and higher rates of morbidity and mortality. Chinese herbal medicine (CHM) is typically characterized as cost-effective and suitable for long-term use with few side effects. To better understand the effects of CHM on hip fracture patients, we utilized a population-based database to investigate the demographic characteristics, cumulative incidence of overall mortality, readmission, reoperation, and patterns of CHM prescription. We found that CHM usage was associated with a lower risk of overall mortality [P = 0.0009; adjusted hazard ratio (HR): 0.47, 95% confidence interval (CI): 0.30-0.73], readmission (P = 0.0345; adjusted HR: 0.67, 95% CI: 0.46-0.97), and reoperation (P = 0.0009; adjusted HR: 0.57, 95% CI: 0.40-0.79) after adjustment for age, type of hip fracture, surgical treatment type, and comorbidities. We also identified the herbal formulas, single herbs, and prescription patterns for the treatment of hip fracture by using association rule mining and network analysis. For hip fracture patients, the most common CHM coprescription pattern was Du-Zhong (DZ) → Xu-Duan (XD), followed by Du-Huo-Ji-Sheng-Tang (DHJST) → Shu-Jing-Huo-Xue-Tang (SJHXT), and Gu-Sui-Bu (GSB) → Xu-Duan (XD). Furthermore, XD was the core prescription, and DZ, GSB, SJHXT, and DHJST were important prescriptions located in cluster 1 of the prescription patterns. This study provides evidence for clinical CHM use as an adjunctive therapy that offers benefits to hip fracture patients.

Abstract
Chondrosarcoma is the second most prevalent general primary tumor of bone following osteosarcoma. Chondrosarcoma development may be linked to angiogenesis, which is principally elicited by vascular endothelial growth factor-A (VEGF-A). VEGF-A level has been recognized as a prognostic marker in angiogenesis. WNT1-inducible signaling pathway protein-3 (WISP)-3/CCN6 belongs to the CCN family and is involved in regulating several cellular functions, including cell proliferation, differentiation, and migration. Nevertheless, the effect of WISP-3 on VEGF-A production and angiogenesis in human chondrosarcoma remains largely unknown. This current study shows that WISP-3 promoted VEGF-A production and induced angiogenesis of human endothelial progenitor cells. Moreover, WISP-3-enhanced VEGF-A expression and angiogenesis involved the c-Src and p38 signaling pathways, while miR-452 expression was negatively affected by WISP-3 via the c-Src and p38 pathways. Our results illustrate the clinical significance of WISP-3, VEGF-A and miR-452 in human chondrosarcoma patients. WISP-3 may illustrate a novel therapeutic target in the metastasis and angiogenesis of chondrosarcoma.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE In Taiwan, lung cancer remains one of the deadliest cancers. Survival of lung cancer patients remains low, ranging from 6% to 18%. Studies have shown that Chinese herbal medicine (CHM) can be used to induce cell apoptosis and exhibit anti-inflammatoryanti-inflammatory activities in cancer cells. AIM OF THE STUDY This study aimed to investigate the frequencies and patterns of CHM treatment for lung cancer patients and the effect of CHM on their survival probability in Taiwan. MATERIALS AND METHODS We identified 6939 lung cancer patients (ICD-9-CM: 162). We allocated 264 CHM users and 528 CHM-non users, matched for age, gender, duration, and regular treatment. Chi-square test, conditional multivariable logistic regression, Kaplan-Meier method, and the log-rank test were used in this study. RESULTS The CHM group was characterized by a longer follow up time and more cases of hyperlipidemia and liver cirrhosis. This group exhibited a lower mortality hazard ratio (0.48, 95% confidence interval [0.39-0.61], p < 0.001), after adjusting for comorbidities. The trend was also observed that the cumulative survival probability was higher in CHM than in non-CHM users (p < 0.0001, log rank test). Analysis of their CHM prescription pattern revealed that Bu-Zhong-Yi-Qi-Tang (BZYQT), Xiang-Sha-Liu-Jun-Zi-Tang (XSLJZT), and Bai-He-Gu-Jin-Tang (BHGJT); and Bei-Mu (BM), Xing-Ren (XR) and Ge-Gen (GG) were found to be the top three formulas and herbs, respectively. Among them, BM was the core CHM of the major cluster, and Jie-Geng (JG) and Mai-Men-Dong-Tang (MMDT) were important CHMs by CHM network analysis. CONCLUSION The use of CHM as an adjunctive therapy may reduce the mortality hazard ratio of lung cancer patients. The investigation of their comprehensive CHM prescription patterns might be useful in future large-scale, randomized clinical investigations of agent effectiveness, safety, and potential interactions with conventional treatments for lung cancer patients.

Abstract
Objective: To explore the gender differences of rapid-eye-movement (REM) related obstructive sleep apnea-hypopnea syndrome (OSAHS). Methods: Consecutive patients with primary complaint of snoring from Sleep Medicine Center of West China Hospital between January 2016 and November 2016 were included in the study. All participants underwent one night polysomnography (PSG) and Epworth sleep scale (ESS) was estimated. The patients diagnosed with OSAHS were classified as REM related OSAHS (REM-OSAHS group) and non-rapid-eye-movement (NREM) related OSAHS (NREM-OSAHS group) based on the PSG parameters. And the gender differences of demographic and polysomnograpic characteristics in both groups were compared. The associations between apnea-hypopnea index (AHI) and body mass index (BMI), neck circumference and waist circumference among patients with OSAHS were explored by multiple linear regression analysis. Results: A total of 1 258 patients were diagnosed with OSAHS. There were 997 (79.3%) male and 261 (20.7%) female among these patients, the mean age was (46.4±12.0) years old and mean BMI was (26.6±3.4) kg/m(2). There were 236 patients (18.8%) classified into REM-OSAHS group, and 1 022 patients (81.2%) classified into NREM-OSAHS group; the proportion of REM-OSAHS in female was significantly higher than that in male (34.1% vs 14.7%, P<0.001). After controlling for age, drinking, smoking, hypnotics, coffee, strong tea and sleep related parameters, in NREM-OSAHS group, AHI was positively correlated with BMI, neck circumference and waist circumference (P<0.001) both in male and female. In REM-OSAHS group, AHI was positively correlated with BMI, neck circumference and waist circumference in female (P<0.05), but only significantly correlated with BMI and waist circumference in male (P<0.05). Conclusions: REM-OSAHS is commonly seen in female OSAHS patients. Evaluation of the influences of anthropometric data on the severity of REM-OSAHS should consider the impact of gender.

Abstract
KCNQ1 encodes a potassium voltage-gated channel and represents a susceptibility locus for type 2 diabetes mellitus (T2DM). Here, we explored the association between KCNQ1 polymorphisms and hypertension risk in individuals with T2DM, as well as the role of KCNQ1 in vascular smooth muscle cell contraction in vitro. To investigate the relationship between KCNQ1 and the risk of developing hypertension in patients with T2DM, we divided the T2DM cohort into hypertension (n = 452) and non-hypertension (n = 541) groups. The Mann-Whitney U test, chi-square test, and multivariate regression analyses were used to assess the clinical characteristics and genotypic frequencies. In vitro studies utilized the rat aortic smooth muscle A10 cell line. Patients in the hypertension group were significantly older at the time of enrollment and had higher levels of body mass index, waist-to-hip ratio, and triglyceride than those in the non-hypertension group. The KCNQ1 rs3864884 and rs12576239 genetic variants were associated with hypertension in T2DM. KCNQ1 expression was lower in the individuals with the CC versus the CT and TT genotypes. Smooth muscle cell contractility was inhibited by treatment with a KCNQ1 inhibitor. These results suggest that KCNQ1 might be associated with hypertension in individuals with T2DM.

Abstract
Objective: To examine the association between subjective sleepiness and objective sleepiness in Chinese obstructive sleep apnea hypopnea syndrome (OSAHS) patients. Methods: A total of 1 660 patients meeting the diagnostic criteria of OSAHS based on overnight polysomnography from West China Hospital, Sichuan University in the period from Jul 2010 to Jul 2014 were enrolled in the study. The Epworth Sleepiness Scale (ESS) and Multiple Sleep Latency Test (MSLT) were to evaluate subjective and objective sleepiness, respectively. The subjects were categorized into quartiles [A (0-4) (n=406), B (5-7) (n=325), C (8-12) (n=443), D(13-24) (n=486) groups] based on the ESS score distribution. Survival analysis was used to characterize the association between the ESS score and the mean sleep latency (MSL). Results: The apnea hypopnea index (AHI) in D group was higher than other three groups [(58.7±26.1) vs (36.8±24.2), (42.6±26.7), (45.7±26.6) events/h, all P<0.05]. The mean sleep latency in D group was shorter than other three groups [(8.0±4.6) vs (10.9±4.4), (10.3±4.8), (9.4±4.5) min, all P<0.05]. The Kaplan-Meier survivor functions across the ESS score quartiles were distinct and fourth quartiles were progressively associated with a greater tendency for falling asleep (χ(2)=77.76, P<0.001 by Log-rank test) in the daytime (The percentages of awaking patients in fourth quartiles were progressively lower at the same time). The adjusted hazard ratios for sleep onset during the MSLT for the group B, C and D were 1.05 (95%CI: 0.90-1.22), 1.22 (95%CI: 1.07-1.40), and 1.38 (95%CI: 1.20-1.60), respectively, comparing to group A. Conclusion: Subjective report of daytime sleepiness is consistent with the objective sleepiness in OSAHS patients.

Abstract
Osteoporosis is a common skeletal disorder, resulting from an imbalance in bone resorption relative to formation. Bone morphogenetic protein (BMP) is a key regulator in bone formation and osteoblastic differentiation. Hence, compounds that promote BMP expression may be suitable candidates for osteoporosis treatment. This study examined the effects of the traditional Chinese medicinal agent, Kuei-Lu-Er-Xian-Jiao (KLEXJ), on BMP-2 production in osteoblasts. We found that KLEXJ extract promoted osteoblastic differentiation marker ALP activity and increased BMP-2 production; pretreatment with PI3K and Akt inhibitors, or small interfering RNA (siRNA), reduced these effects. KLEXJ also enhanced PI3K and Akt phosphorylation. Treatment of osteoblastic cells with NF-κB inhibitors (TPCK or PDTC) markedly inhibited KLEXJ-enhancement of ALP activity and BMP-2 production. KLEXJ also significantly promoted p65 phosphorylation, while treatment with PI3K and Akt inhibitors antagonized KLEXJ-enhanced p65 phosphorylation. Thus, KLEXJ enhances ALP activity and BMP-2 production of osteoblasts through the PI3K/Akt/ NF-κB signaling pathway and hence may be suitable in the treatment of osteoporosis.

Abstract
Pathophysiological events that modulate the progression of structural changes in osteoarthritis (OA) include the secretion of inflammatory molecules, such as proinflammatory cytokines. Interleukin-1beta (IL-1β) is the prototypical inflammatory cytokine that activates OA synovial cells to release cytokines and chemokines in support of the inflammatory response. The monocyte chemoattractant protein-1 (MCP-1/CCL2) is one of the key chemokines that regulate migration and infiltration of monocytes in response to inflammation. We show in this study that IL-1β-induced MCP-1 expression and monocyte migration in OA synovial fibroblasts (OASFs) is effectively inhibited by soya-cerebroside, an extract of Cordyceps militaris. We found that soya-cerebroside up-regulated of microRNA (miR)-432 expression via inhibiting AMPK and AKT signaling pathways in OASFs. Soya-cerebroside also effectively decreased monocyte infiltration and prevented cartilage degradation in a rat inflammatory model. Our findings are the first to demonstrate that soya-cerebroside inhibits monocyte/macrophage infiltration into synoviocytes, attenuating synovial inflammation and preventing cartilage damage by reducing MCP-1 expression in vitro and in vivo. Taken together, we suggest a novel therapeutic strategy based on the use of soya-cerebroside for the management of OA.

ACTA ACUST UNITED AC 2017; 50:e5252. [PMID: 28146216 PMCID: PMC5304216 DOI: 10.1590/1414-431x20165252] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/10/2016] [Accepted: 09/29/2016] [Indexed: 12/31/2022]
Abstract
We evaluated serum total bilirubin levels as a predictor for metabolic syndrome (MetS) and investigated the relationship between serum total bilirubin levels and MetS prevalence. This cross-sectional study included 1728 participants over 65 years of age from Eastern China. Anthropometric data, lifestyle information, and previous medical history were collected. We then measured serum levels of fasting blood-glucose, total cholesterol, triglycerides, and total bilirubin, as well as alanine aminotransferase activity. The prevalence of MetS and each of its individual component were calculated per quartile of total bilirubin level. Logistic regression was used to assess the correlation between serum total bilirubin levels and MetS. Total bilirubin level in the women who did not have MetS was significantly higher than in those who had MetS (P<0.001). Serum total bilirubin quartiles were linearly and negatively correlated with MetS prevalence and hypertriglyceridemia (HTG) in females (P<0.005). Logistic regression showed that serum total bilirubin was an independent predictor of MetS for females (OR: 0.910, 95%CI: 0.863-0.960; P=0.001). The present study suggests that physiological levels of serum total bilirubin might be an independent risk factor for aged Chinese women, and the prevalence of MetS and HTG are negatively correlated to serum total bilirubin levels.

Abstract
Connective tissue growth factor (CTGF; also known as CCN2) is an inflammatory mediator that is abundantly expressed in osteoarthritis (OA). Interleukin-1β (IL-1β) plays a pivotal role in OA pathogenesis. Berberine exhibits an anti-inflammatory effect, but the mechanisms by which it modulates CCN2-induced IL-1β expression in OA synovial fibroblasts (OASFs) remain unknown. We showed that CCN2-induced IL-1β expression is mediated by the activation of αvβ3/αvβ5 integrin-dependent reactive oxygen species (ROS) generation, and subsequent activation of apoptosis signal-regulating kinase 1 (ASK1), p38/JNK, and nuclear factor-κB (NF-κB) signaling pathways. This IL-1β expression in OASFs is attenuated by N-acetylcysteine (NAC), inhibitors of ASK1, p38, or JNK, or treatment with berberine. Furthermore, berberine also reverses cartilage damage in an experimental model of collagenase-induced OA (CIOA). We observed that CCN2 increased IL-1β expression via αvβ3/αvβ5 integrins, ROS, and ASK1, p38/JNK, and NF-κB signaling pathways. Berberine was found to inhibit these signaling components in OASFs in vitro and prevent cartilage degradation in vivo. We suggest a novel therapeutic strategy of using berberine for managing OA.

Abstract
BACKGROUND This study investigated the clinical efficacy of electroacupuncture (EA) in inhibiting upper-extremity spasticity in chronic stroke patients, and also in mapping a unique preliminary acupoint-selection protocol. METHODS Fifteen patients were divided into two groups: patients in the control group (n=6) received minimal acupuncture (MA), and those in the experimental group (n=9) received EA. Four acupoints, which include Neiguan (PC6), Shaohai (HT3), Zeqian (Ex-UE, A32), and Shounizhu (EX-UE), were treated near the motor points of the muscles for elbow flexion, forearm pronation, and finger flexion. Both groups were treated for twelve sessions, 20 minutes per session, for 6 weeks (two sessions per week). The outcome measures in this study included angle of muscle reaction (R1), passive range of motion (R2), and dynamic component (R2-R1). RESULTS In the experimental group, the R2-R1 of the elbow joint was significantly decreased at 1 (P=0.0079), 3 (P=0.0013), and 6 weeks (P=0.0149) after treatment compared with pretreatment levels (P<0.05). The between-group difference in the R2-R1 of the elbow joint after the 6-week treatment was statistically significant. CONCLUSION Combining the 6-week EA and standard rehabilitation treatment reduced the spasticity of the elbow for chronic stroke survivors. However, no significant effect was observed in the spasticity of the wrist joints. The choice of acupoints and the frequency of EA have to be taken into account to achieve a positive treatment effect. The correlation between acupoints and motor points provides a model of acupoint selection to improve spasticity.

Abstract
The establishment of abaxial-adaxial polarity is an important feature of the development of lateral organs in plants. Members of the YABBY gene family may be specific to seed-plant-specific transcriptional regulators that play critical roles in promoting abaxial cell fate in the model eudicot, Arabidopsis thaliana. However, recent study has shown that the roles of YABBY genes are not conserved in the development of angiosperms. The establishment of abaxial-adaxial polarity has not been studied in perennial fruit crops. Grapes are an important fruit crop in many regions of the world. Investigating YABBY genes in grapevines should help us to discover more about the key genetic and molecular pathways in grapevine development. To understand the characterization of YABBY genes in grapevines, two YABBY genes, VpYABBY1 (GenBank accession No. KC139089) and VpYABBY2 (GenBank accession No. KC139090), were isolated from the wild Chinese species Vitis pseudoreticulata. Both of these encode YABBY proteins. Sequence characterization and phylogenetic analyses show that VpYABBY1 is group classified into the FIL subfamily while VpYABBY2 is a member of the YAB2 subfamily of Arabidopsis thaliana. Subcellular localization analysis indicates that VpYABBY1 and VpYABBY2 proteins are localized in the nucleus. Tissue specific expressional analysis reveals that VpYABBY1 is expressed strongly in young leaves of grape but only weakly in the mature leaves. Meanwhile, VpYABBY2 is expressed in grape stems, flowers, tendrils, and leaves. Transgenic Arabidopsis plants ectopically expressing VpYABBY1 caused the partial abaxialization of the adaxial epidermises of leaves, behaving similarly to those over-expressing FIL or YAB3 with abaxialized lateral organs. By contrast, ectopic expression of VpYABBY2 in Arabidopsis did not cause any alteration in the adaxial-abaxial polarity. Sequence characterization and phylogenetic analysis revealed that VpYABBY1 and VpYABBY2 are group-classified into two different subfamilies. They have diverged functionally in the control of lateral organ development. VpYABBY1 may have a function in leaf development, while VpYABBY2 may play a specific role in carpel development and grape berry morphogenesis. It is further possible that during the evolution of different species, YABBY family members have preserved different expression regulatory systems and functions.

Abstract
BACKGROUND Si-Wu-Tang (SWT), a Traditional Chinese Medicine (TCM) formula, is widely used for the treatment of gynopathies diseases such as menstrual discomfort, climacteric syndrome, dysmenorrhea, and other estrogen-related diseases. Recent studies have shown that SWT can treat primary dysmenorrhea, have anti-pruritic anti-inflammatory effects, and protect against radiation-induced bone marrow damage in an animal model. It has been reported that anti-inflammatory and anti-oxidant agents have the potential to treat osteoporosis by increasing bone formation and/or suppressing bone resorption. However, the effect of SWT on bone cell function has not yet been reported. METHODS Alkaline phosphatase (ALP), bone morphogenetic proteins (BMP)-2, and osteopontin (OPN) mRNA expression was analyzed by qPCR. The mechanism of action of SWT extract was investigated using western blotting. The in vivo anti-osteoporotic effect of SWT extract was assessed in ovariectomized mice. RESULTS Here, we report that SWT increases ALP, BMP-2, and OPN expression as well as bone mineralization. In addition, we show that the PI3K, Akt, and NF-κB signaling pathways may be involved in the SWT-mediated increase in gene expression and bone mineralization. Notably, treatment of mice with SWT extract prevented bone loss induced by ovariectomy in vivo. CONCLUSION SWT may be used to stimulate bone formation for the treatment of osteoporosis.

Abstract
Chondrosarcoma is a primary malignant bone cancer, with a potent capacity to invade locally and cause distant metastasis; it has a poor prognosis and shows a predilection for metastasis to the lungs. Brain derived neurotrophic factor (BDNF) is a small-molecule protein from the neurotrophin family of growth factors that is associated with the disease status and outcomes of cancers. However, the effect of BDNF on migration activity in human chondrosarcoma cells is mostly unknown. Here, we found that human chondrosarcoma tissues showed significant expression of BDNF, which was higher than that in normal cartilage and primary chondrocytes. We also found that BDNF increased the migration and expression of β5 integrin in human chondrosarcoma cells. In addition, knockdown of BDNF expression markedly inhibited migratory activity. BDNF-mediated migration and β5 integrin up-regulation were attenuated by antibody, inhibitor, or siRNA against the TrkB receptor. Pretreatment of chondrosarcoma cells with PI3K, Akt, and NF-κB inhibitors or mutants also abolished BDNF-promoted migration and integrin expression. The PI3K, Akt, and NF-κB signaling pathway was activated after BDNF treatment. Taken together, our results indicate that BDNF enhances the migration of chondrosarcoma by increasing β5 integrin expression through a signal transduction pathway that involves the TrkB receptor, PI3K, Akt, and NF-κB. BDNF thus represents a promising new target for treating chondrosarcoma metastasis.

Abstract
Interleukin-11 (IL-11) was originally identified as the cytokine that could induce the proliferation of human cells. Recent studies have shown that IL-11 plays a critical role in tumor growth, angiogenesis, and metastasis. Chondrosarcoma is a type of highly malignant tumor with a potent capacity to invade locally and cause distant metastasis. However, the effects of IL-11 on human chondrosarcoma cells are largely unknown. Here, we found that IL-11 increased the migration and expression of intercellular adhesion molecule-1 (ICAM)-1 in human chondrosarcoma cells. We also found that human chondrosarcoma tissues had significant expression of the IL-11 which was higher than that in primary chondrocytes. The phosphatidylinositol 3-kinase (PI3K), Akt, and NF-κB pathways were activated by IL-11 treatment, and the IL-11-induced expression of ICAM-1 and migration activity were inhibited by the specific inhibitors and mutant forms of PI3K, Akt, and NF-κB cascades. Taken together, our results indicate that IL-11 enhanced the migration of the chondrosarcoma cells by increasing ICAM-1 expression through the IL-11Rα receptor, PI3K, Akt, and NF-κB signal transduction pathway.

Abstract
Chondrosarcoma is a type of highly malignant tumor with a potent capacity for local invasion and causing distant metastasis. Chondrosarcoma shows a predilection for metastasis to the lungs. Hepatocyte growth factor (HGF) has been demonstrated to stimulate cancer proliferation, migration, and metastasis. However, the effect of HGF on migration activity of human chondrosarcoma cells is not well known. Here, we found that human chondrosarcoma tissues demonstrated significant expression of HGF, which was higher than that in normal cartilage. We also found that HGF increased the migration and expression of matrix metalloproteinase (MMP)-2 in human chondrosarcoma cells. c-Met inhibitor and siRNA reduced HGF-increased cell migration and MMP-2 expression. HGF treatment resulted in activation of the phosphatidylinositol 3'-kinase (PI3K)/Akt/PKCδ/NF-κB pathway, and HGF-induced expression of MMP-2 and cell migration was inhibited by specific inhibitors or siRNA-knockdown of PI3K, Akt, PKCδ, and NF-κB cascades. Taken together, our results indicated that HGF enhances migration of chondrosarcoma cells by increasing MMP-2 expression through the c-Met receptor/PI3K/Akt/PKCδ/NF-κB signal transduction pathway.

Abstract
Background Incomplete bladder emptying (IBE) is defined as having a postvoid residual (PVR) urine volume greater than 100 mL for 2 consecutive days. IBE is common in stroke patients and could necessitate indwelling or intermittent catheterization. The condition is correlated with urinary tract infections, which could impede rehabilitation progress and increase medical costs. Treatment for patients with IBE includes bladder retraining, biofeedback, medication, and botulinum toxin injection, but none of these interventions are completely effective. Methods All patients with acute stroke who were admitted to the rehabilitation ward between August 2010 and April 2011 were included in the study and their PVR urine volume was checked. Electroacupuncture (EA; 1 Hz, 15 minutes) was performed on the acupoints Sanyinjiao (SP6), Ciliao (BL32), and Pangguangshu (BL28) of stroke patients with IBE for a total of ten treatments (five times a week for 2 weeks). Bladder diaries, which included the spontaneous voiding and PVR urine volumes, were recorded during the course of treatment. Results The presence of IBE was not related to sex, history of diabetes mellitus, stroke type (hemorrhagic or ischemic), or stroke location (P > 0.05). Among the 49 patients in the study, nine (18%) had IBE, and seven of the stroke patients with IBE were treated with EA. Increased spontaneous voiding volume and decreased PVR urine volume were noted after ten sessions of EA. Conclusion EA may have beneficial effects on stroke survivors with IBE, thereby making it a potential safe modality with which to improve urinary function.
