        Interaction between Warfarin and the Herbal Product Shengmai-Yin: A Case Report of Intracerebral Hematoma

        Qun Su,Yuhong Li 연세대학교의과대학 2010 Yonsei medical journal Vol.51 No.5

        A 71-year-old man was stable on warfarin (2.25 mg daily) therapy with an international normalized ratio (INR) of 1.8-2.2 after a heart valve replacement surgery. Recently, he consumed the liquid-like herbal product called shengmai-yin (10 mL daily) against medical advice. Seven days after the daily consumption of shengmai-yin, he was admitted to the intensive care unit because of consciousness disturbance [Glasgow Coma Scale (GCS) score 7] with an INR of 5.08. Head computed topography revealed intracerebral hematoma in the left temporoparietal region. Both warfarin therapy and the herbal product were withdrawn. At the same time, therapy with intravenous vitamin K1 40 mg was started. On the second day of admission, craniectomy was performed to remove the intacerebral hematoma under general anesthesia. He remained confused and restless for 2 days, but then showed progressive recovery in the consciousness level as well as motor and verbal functions. Shengmai-yin contains herbal ingredients that can interact with warfarin. The Drug Interaction Probability Scale (DIPS) indicated that warfarin and shengmai-yin were highly probable causes of intracerebral hematoma. Patients on warfarin therapy should be discouraged from taking herbal medicines,especially preparations that are already known to have antiplatelet and antithrombotic effects.

        Antibacterial Activity of Organic Acids in Aqueous Extracts from Pine Needles (Pinus massoniana Lamb.)

        Su Feng,Weicai Zeng,Fan Luo,Jian Zhao,Zhirong Yang,Qun Sun 한국식품과학회 2010 Food Science and Biotechnology Vol.19 No.1

        Pine needle (Pinus massoniana Lamb.) of large quantity in China and health benefit makes its application on pharmaceutical and food industry in high demand. The chemical composition of pine needle aqueous extract (PNAE) analyzed by gas chromatograph-mass spectrometry revealed that among more than 10 compounds in PNAE,organic acids were over 76.92%, with acetic acid being 25.20%, hexadecanoic acid 18.19%, and 2-methoxy-4-vinylphenol 16.44%. Ultra-performance liquid chromatography-mass spectrometry disclosed other 5 short chain organic acids, including citric acid, succinic acid, malonic acid, malic acid, and oxalic acid. The antibacterial activity of PNAE on common spoilages and pathogenic bacteria showed that the growth of Bacillus subtilis, Staphylococcus aureus, Bacillus cereus, Micrococcus luteus, Escherichia coli, and Proteus vulgaris were inhibited significantly, with minimum inhibitory concentrations and minimum bactericidal concentrations being 3.8-15 and 7.5-30 mg/mL, respectively. Our findings suggested that pine needles with effective and safe antibacterial components possess the potential to be developed into efficacious natural antiseptic products for food disinfection and medical purpose.

        Transcriptional Analysis of 10 Selected Genes in a Model of Penicillin G Induced Persistence of Chlamydophila psittaci in HeLa Cells

        ( Yan Qun Hu ),( Li Li Chen ),( Chuan Wang ),( Ya Feng Xie ),( Zhi Xi Chen ),( Liang Zhuan Liu ),( Ze Hong Su ),( Yi Mou Wu ) 한국미생물 · 생명공학회 2015 Journal of microbiology and biotechnology Vol.25 No.8

        Chlamydophila psittaci is an important intracellular pathogen. Persistent infection is an important state of the host-parasite interaction in this chlamydial infection, which plays a significant role in spreading the organism within animal populations and in causing chronic chlamydiosis and serious sequelae. In this study, a C. psittaci persistent infection cell model was induced by penicillin G, and real-time quantitative PCR was used to study the transcriptional levels of 10 C. psittaci genes (dnaA, dnaK, ftsW, ftsY, grpE, rpsD, incC, omcB, CPSIT_0846, and CPSIT_0042) in acute and penicillin-G-induced persistent infection cultures. Compared with the acute cultures, the penicillin-G-treated cultures showed a reduced chlamydial inclusion size and a significantly decreased number of elementary body particles. Additionally, some enlarged aberrant reticulate body particles were present in the penicillin- G-treated cultures but not the acute ones. The expression levels of genes encoding products for cell division (FtsW, FtsY) and outer membrane protein E encoding gene (CPSIT_0042) were downregulated (p < 0.05) from 6 h post-infection onward in the persistent infection cultures. Also from 6 h post-infection, the expression levels of DnaA, DnaK, IncC, RpsD, GrpE, and CPSIT_0846 were upregulated (p < 0.05); however, the expression level of OmcB in the persistent infection was almost the same as that in the acute infection (p > 0.05). These results provide new insight regarding molecular activities that accompany persistence of C. psittaci, which may play important roles in the pathogenesis of C. psittaci infection.

      • Predicament, Opportunity and Path: Reflections on the Development of Tai Chi in the New Era

        LI Qun,FENG CHAO-Hai,LEI Tao,WU Zh-iheng,SU Jian-jiao 아시아건강운동학회 2021 Journal of Asian Society for Health & Exercise Vol.3 No.2

        The new era has entrusted the era mission of high-quality development of Tai Chi. Standing in a new historical position, this thesis uses the method of literature and logical analysis to explore the realistic difficulties, opportunities of the times and breakthrough paths in the development of Tai Chi, which is a reflection on the breakthrough of the development of it. The research believes that the development of Tai Chi in the new era has the predicament of slow domestic and international development, the gradual dissipation of martial arts functions, and the gradual weakening of cultural attributes. However, the new era has also brought a new opportunity for the Tai Chi movement to have a clearer development blueprint, a more stable social foundation, and a healthy concept deeply rooted in the hearts of the people. The development of Tai Chi in the new era should be guided by a new pattern of domestic development and international promotion. The development of Tai Chi in the new era should be guided by the construction of a new dual-cycle pattern of domestic development and international promotion, the strategy of coordinating the balance of Tai Chi sports competition and fitness functions, and the means of the integration of school education and cultural exchange, so as to realize the high-quality development of Tai Chi.

        Overexpression of Long Non-Coding RNA HOTAIR Promotes Tumor Growth and Metastasis in Human Osteosarcoma

        Wang, Bo,Su, Yun,Yang, Qun,Lv, Decheng,Zhang, Weiguo,Tang, Kai,Wang, Hong,Zhang, Rui,Liu, Yang Korean Society for Molecular and Cellular Biology 2015 Molecules and cells Vol.38 No.5

        Human osteosarcoma usually presented a high tendency to metastatic spread and caused poor outcomes, however, the underlying mechanism was still largely unknown. In the present study, using a series of in vitro experiments and an animal model, we investigated the roles of HOX antisense intergenic RNA (HOTAIR) during the proliferation and invasion of osteosarcoma. According with our results, HOTAIR was commonly overexpressed in osteosarcoma, which significantly correlated with advanced tumor stage, highly histological grade and poor prognosis. In vitro and in vivo experiments demonstrated that knockdown of HOTAIR could notably suppress cellular proliferation, inhibit invasion and decrease the secretion of MMP2 and MMP9 in osteosarcoma. Collectively, our results suggested that HOTAIR might be a potent therapeutic target for osteosarcoma.

      • The Effects of Tai Chi Intervention on Healthy Elderly by Means of Neuroimaging and EEG: A Systematic Review

        Pan, Zhujun,Su, Xiwen,Fang, Qun,Hou, Lijuan,Lee, Younghan,Chen, Chih C.,Lamberth, John,Kim, Mi-Lyang Frontiers Media S.A. 2018 FRONTIERS IN AGING NEUROSCIENCE Vol.10 No.-

        <P>Aging is a process associated with a decline in cognitive and motor functions, which can be attributed to neurological changes in the brain. Tai Chi, a multimodal mind-body exercise, can be practiced by people across all ages. Previous research identified effects of Tai Chi practice on delaying cognitive and motor degeneration. Benefits in behavioral performance included improved fine and gross motor skills, postural control, muscle strength, and so forth. Neural plasticity remained in the aging brain implies that Tai Chi-associated benefits may not be limited to the behavioral level. Instead, neurological changes in the human brain play a significant role in corresponding to the behavioral improvement. However, previous studies mainly focused on the effects of behavioral performance, leaving neurological changes largely unknown. This systematic review summarized extant studies that used brain imaging techniques and EEG to examine the effects of Tai Chi on older adults. Eleven articles were eligible for the final review. Three neuroimaging techniques including fMRI (<I>N</I> = 6), EEG (<I>N</I> = 4), and MRI (<I>N</I> = 1), were employed for different study interests. Significant changes were reported on subjects' cortical thickness, functional connectivity and homogeneity of the brain, and executive network neural function after Tai Chi intervention. The findings suggested that Tai Chi intervention give rise to beneficial neurological changes in the human brain. Future research should develop valid and convincing study design by applying neuroimaging techniques to detect effects of Tai Chi intervention on the central nervous system of older adults. By integrating neuroimaging techniques into randomized controlled trials involved with Tai Chi intervention, researchers can extend the current research focus from behavioral domain to neurological level.</P>

      • Efficient Promotion of Autophagy and Angiogenesis Using Mesenchymal Stem Cell Therapy Enhanced by the Low-Energy Shock Waves in the Treatment of Erectile Dysfunction

        Zhu, Guan Qun,Jeon, Seung Hwan,Bae, Woong Jin,Choi, Sae Woong,Jeong, Hyun Cheol,Kim, Kang Sup,Kim, Su Jin,Cho, Hyuk Jin,Ha, U. Syn,Hong, Sung Hoo,Lee, Ji Youl,Kwon, Eun Bi,Kim, Sae Woong Hindawi 2018 Stem cells international Vol.2018 No.-

        <P><B>Background</B></P><P> Mesenchymal stem cell therapy (MSCT) and defocused low-energy shock wave therapy (ESWT) has been shown to ameliorate erectile dysfunction (ED). However, the interactions and effects of action between MSCT and ESWT remain poorly understood. In this study, we investigated the mechanisms of combination therapy with MSCT and ESWT in a rat model of diabetic ED. </P><P><B>Materials and Methods</B></P><P> Eight-week-old male Sprague-Dawley rats were randomly divided into 2 parts. Diabetic rats induced by streptozotocin (65 mg/kg) were randomly divided into 4 groups: (1) DM control group, (2) DM + ESWT group, (3) DM + MSCT group, and (4) DM + ESWT + MSCT group. The sham group was a normal control group (without streptozotocin). MSCT and (or) ESWT were, respectively, administered to each group according to the proposal for 8 weeks. Immediately after recording of intracavernous pressure (ICP), the penis was then harvested for histologic analysis, ELISA, and Western blotting. </P><P><B>Results</B></P><P> The ratio of ICP/MAP was significantly higher in the DM + ESWT + MSCT group than in ESWT or MSCT treated group (<I>P</I> < 0.05). Also, the treatment stimulated angiogenesis and vasodilatation in the corpus cavernosum (<I>P</I> < 0.05). ESWT increased the quantity of MSCs in the corpus cavernosum and also induced MSCs to express more VEGF in vitro and vivo (<I>P</I> < 0.05) which activated the PI3K/AKT/mTOR and NO/cGMP signaling pathways in the corpus cavernosum. The combination approach stimulated autophagy and decreased apoptosis in the corpus cavernosum. NGF and BDNF expressions were higher in the DM + ESWT + MSCT group than in the DM control group (<I>P</I> < 0.01). Furthermore, the treatment promoted the MSC recruitment by inducing penile tissues to express more PECAM and SDF-1. </P><P><B>Conclusions</B></P><P> Combination of LI-ESWT and MSCT can get a better result than a single treatment by expressing more VEGF which can take part in autophagy by triggering the PI3K/AKT/mTOR signaling pathway. This cooperative therapy would provide a new research direction in ED treatment for the future.</P>

        Yu-Jie Su,Jian-Qun Lin,Jian-Qiang Lin,Dong-Hui Hao 한국생물공학회 2009 Biotechnology and Bioprocess Engineering Vol.14 No.5

        The recombinant Escherichia coli(E.coli) expressing human hepatic metallothionein_IA (hMT_IA) was constructed for bioaccumulation of Arsenic (As). The gene sequence of hMT_IA was modified for codon preference of E.coli and synthesized using chemical method. The vector of pGEX_4T_1 was used=and hMT_IA was expressed as the fusion protein with glutathione S-transferase (GST) tag. The bioaccumulation capability of arsenite compounds As(III) of the recombinant E.coli increased more than 3-fold from 76.3 to 319.6 μg/g dry cells compared with the control. The conditions of 50 μM of As(III) and low pHs were optimal for As(III) bioaccumulation. The heavy metals of Cd, Hg, and Zn inhibited As(III) bioaccumulation. The bioaccumulation reached 70% of the saturated value within 1 h. The recombinant E.coli will be useful in bioremediation of arsenic or other kinds of heavy metal contaminated water.

      • Clinicopathologic Characteristics and Prognoses for Multicentric Occurrence and Intrahepatic Metastasis in Synchronous Multinodular Hepatocellular Carcinoma Patients

        Li, Shi-Lai,Su, Ming,Peng, Tao,Xiao, Kai-Yin,Shang, Li-Ming,Xu, Bang-Hao,Su, Zhi-Xiong,Ye, Xin-Ping,Peng, Ning,Qin, Quan-Lin,Chen, De-Feng,Chen, Jie,Li, Le-Qun Asian Pacific Journal of Cancer Prevention 2013 Asian Pacific journal of cancer prevention Vol.14 No.1

        Background: Hepatocellular carcinoma (HCC) is one of the most common cancers worldwide, and the outcomes for patients are still poor. It is important to determine the original type of synchronous multinodular HCC for preoperative assessment and the choice of treatment therapy as well as for the prediction of prognosis after treatment. Aims: To analyze clinicopathologic characteristics and prognoses in patients with multicentric occurrence (MO) and intrahepatic metastasis (IM) of synchronous multinodular hepatocellular carcinoma (HCC). Methods: The study group comprised 42 multinodular HCC patients with a total of 112 nodules. The control group comprised 20 HCC patients with 16 single nodular HCC cases and 4 HCC cases with a portal vein tumor emboli. The mitochondrial DNA (mtDNA) D-loop region was sequenced, and the patients of the study group were categorized as MO or IM based on the sequence variations. Univariate and multivariate analyses were used to determine the important clinicopathologic characteristics in the two groups. Results: In the study group, 20 cases were categorized as MO, and 22 as IM, whereas all 20 cases in the control group were characterized as IM. Several factors significantly differed between the IM and MO patients, including hepatitis B e antigen (HBeAg), cumulative tumor size, tumor nodule location, cirrhosis, portal vein and/or microvascular tumor embolus and the histological grade of the primary nodule. Multivariate analysis further demonstrated that cirrhosis and portal vein and/or microvascular tumor thrombus were independent factors differentiating between IM and MO patients. The tumor-free survival time of the MO subjects was significantly longer than that of the IM subjects ($25.7{\pm}4.8$ months vs. $8.9{\pm}3.1$ months, p=0.017). Similarly, the overall survival time of the MO subjects was longer ($31.6{\pm}5.3$ months vs. $15.4{\pm}3.4$ months, p=0.024). The multivariate analysis further demonstrated that the original type (p=0.035) and Child-Pugh grade (p<0.001) were independent predictors of tumor-free survival time. Cirrhosis (p=0.011), original type (p=0.034) and Child-Pugh grade (p<0.001) were independent predictors of overall survival time. Conclusions: HBeAg, cumulative tumor size, tumor nodule location, cirrhosis, portal vein and/or microvascular tumor embolus and histological grade of the primary nodule are important factors for differentiating IM and MO. MO HCC patients might have a favorable outcome compared with IM patients.
