Identification of terpene synthase gene family in Gynostemma pentaphyllum and expression pattern analysis under abiotic stresses / 中国中药杂志

The present study aimed to investigate the composition of the terpene synthase(TPS) gene family in Gynostemma pentaphyllum and its role in abiotic stresses. The G. pentaphyllum TPS gene family was identified and analyzed at the genome-wide level using bioinformatics analysis, and the expression patterns of these family members were analyzed in different tissues of G. pentaphyllum as well as under various abiotic stresses. The results showed that there were 24 TPS gene family members in G. pentaphyllum with protein lengths ranging from 294 to 842 aa. All of them were localized in the cytoplasm or chloroplasts and unevenly distributed on the 11 chromosomes of G. pentaphyllum. The results of the phylogenetic tree showed that the G. pentaphyllum TPS gene family members could be divided into five subfamilies. As revealed by the analysis of promoter cis-acting elements, TPS gene family members in G. pentaphyllum were predicted to respond to a variety of abiotic stresses such as salt, low temperature, and dark stress. The analysis of gene expression patterns in different tissues of G. pentaphyllum revealed that nine TPS genes were tissue-specific in expression. The qPCR results showed that GpTPS16, GpTPS17, and GpTPS21 responded to a variety of abiotic stresses. This study is expected to provide references in guiding the further exploration of the biological functions of G. pentaphyllum TPS genes under abiotic stresses.

Effect of uridine on mitochondrial function / 生物工程学报

Uridine is one of the essential nutrients in organisms. To maintain normal cell growth and intracellular metabolism, the uridine must be maintained at certain concentration. Recent studies have shown that uridine can reduce inflammatory response in organisms, participate in glycolysis, and regulate intracellular protein modification, such as glycosylation and acetylation. Furthermore, it can protect cells from hypoxic injury by reducing intracellular oxidative stress, promoting high-energy compounds synthesis. Previous studies have shown that the protective effects of uridine are closely related to its effect on mitochondria. This review summarizes the effect of uridine on mitochondrial function.

The role of PI3K/Akt signal pathway in the protective effects of propofol on intestinal and lung injury induced by intestinal ischemia/reperfusion

Abstract Purpose: To investigate the role of PI3k/Akt signal pathway in the protective effects of propofol on intestinal and lung injury induced by intestinal ischemia/reperfusion(I/R). Methods: Male Sprague-Dawley rats were subjected to 45 min of ischemia by occluding the superior mesenteric artery and to 2h of reperfusion to establish the model of I/R. Twenty four rats were randomly divided into four groups: Sham, intestinal I/R (II/R), propofol (P), wortmannin (W). In groups P, W, propofol was injected intravenously and continuously at the onset of reperfusion via infusion pump. PI3K inhibitor (wortmannin) was administered intravenously in group W 25 min before ischemia. Intestinal tissues and lung tissues were obtained for determination of histologic injury, wet/dry weight ratio, malondialdehyde (MDA) levels, superoxide dismutase (SOD) and myeloperoxidase (MPO) activities. Meanwhile, the expressions of caspase-3 and phosphorylated Akt (p-Akt) in intestines and lungs were detected by western blot. Results: Propofol treatment alleviated intestinal and lung morphological changes which were observed in II/R group，Moreover, wet/dry weight ratio, the MDA level, MPO activity and expression of caspase-3 were significantly decreased whereas the SOD activity and p-Akt expression were significantly increased. Notably, the protections were significantly reversed by pretreatment of wortmannin. Conclusion: PI3K/Akt pathway activation play a critical role in the protective effects of propofol on intestinal and lung injury induced by ischemia/reperfusion.

Salvianolate reduces murine myocardial ischemia and reperfusion injury via ERK1/2 signaling pathways in vivo / 中国结合医学杂志

<p><b>OBJECTIVE</b>To analyze the effects of salvianolate on myocardial infarction in a murine in vivo model of ischemia and reperfusion (I/R) injury.</p><p><b>METHODS</b>Myocardial I/R injury model was constructed in mice by 30 min of coronary occlusion followed by 24 h of reperfusion and pretreated with salvianolate 30 min before I/R (SAL group). The SAL group was compared with SHAM (no I/R and no salvianolate), I/R (no salvianolate), and ischemia preconditioning (IPC) groups. Furthermore, an ERK1/2 inhibitor PD98059 (1 mg/kg), and a phosphatidylinositol-3-kinase (PI3-K) inhibitor, LY294002 (7.5 mg/kg), were administered intraperitoneal injection (i.p) for 30 min prior to salvianolate, followed by I/R surgery in LY and PD groups. By using a double staining method, the ratio of the infarct size (IS) to left ventricle (LV) and of risk region (RR) to LV were compared among the groups. Correlations between IS and RR were analyzed. Western-blot was used to detect the extracellular signal-regulated kinase 1/2 (ERK1/2) and protein kinase B (AKT) phosphorylation changes.</p><p><b>RESULTS</b>There were no significant differences between RR to LV ratio among the SHAM, I/R, IPC and SAL groups (P>0.05). The SAL and IPC groups had IS of 26.1%±1.4% and 22.3%±2.9% of RR, respectively, both of which were significantly smaller than the I/R group (38.5%±2.9% of RR, P<0.05, P<0.01, respectively). Moreover, the phosphorylation of ERK1/2 was increased in SAL group (P<0.05), while AKT had no significant change. LY294002 further reduced IS, whereas the protective role of salvianolate could be attenuated by PD98059, which increased the IS. Additionally, the IS was not linearly related to the RR (r=0.23, 0.45, 0.62, 0.17, and 0.52 in the SHAM, I/R, SAL, LY and PD groups, respectively).</p><p><b>CONCLUSION</b>Salvianolate could reduce myocardial I/R injury in mice in vivo, which involves an ERK1/2 pathway, but not a PI3-K signaling pathway.</p>

Association of serum concentrations of total testosterone with coronary heart disease in the postmenopausal women / 中华老年医学杂志

Objective To study the association between serum concentrations of total testosterone levels and coronary heart disease (CHD) in the postmenopausal women. Methods The study was designed as a case-control study.394 postmenopausal female patients were selected from Cardiology Center of the First Affiliated Hospital of Xinjiang Medical University.The case group included 183 women patients with CHD aged (62.7±8.0) years,the control group,211 women with normal coronary aged (60.0 ± 8.8) years. Blood samples were collected to determine total testosterone,fasting glucose and lipid profile. CHD severity was expressed as the numbers of coronary arteries that had a stenosis ≥50％.According to the level of testosteron,all cases were divided into 4 groups by interquartile range method:Q1＜3.5 nmol/L(n=190),3.5 nmol/L≤Q2 ＜10.4 nmol/L(n=64),10.4 nmol/L≤Q3 ＜26.0 nmol/L(n=120) and Q4≥26.0 nmol/L(n=20).The association between the serum total testosterone levels and severity of coronary atherosclerosis was analyzed. Results The average total testosterone was higher in case group than in control group[(10.4 ± 24.3 ) nmol/L vs. ( 6.9 ± 17.4 ) nmol/L,Z =0.79,P =0.555].In Quantitative adjusted models,higher levels of total testosterone had strong correlation with CHD,Q4 incidence of CHD (75.0％,15 cases) was significantly higher than Q1 (46.8％,89 cases),Q2 (40.6％,26 cases)and Q3 (44.2％,53 cases) (x2 =7.69,P=0.048).After adjustment for other risk factors,women in the top quartile of total testosterone levels had a more than 3-fold increase in odds of CHD(OR=3.47,95％CI:1.06-11.32,P＜0.05).In addition,the serum concentrations of total testosterone level were significantly associated with the severity of CHD (F=12.94,P＜0.05). Conclusions Higher levels of total testosterone may be associated with high prevalence and severity of CHD as an independent factor in postmenopausal women.

Adherent and single-cell suspension culture of Madin-Darby canine kidney cells in serum-free medium / 生物工程学报

In recent years, there are tremendous economic and social losses across the world because of virus-related diseases. It is well known that Madin-Darby canine kidney (MDCK) cells are easily handled, quickly amplified and efficiently infected with influenza virus. Therefore, they are considered as one of the most important cell lines for the production of influenza vaccine. In this work, we first developed a serum-free adherent culture process for MDCK cells with an in-house prepared serum-free medium MDCK-SFM. Next, we derived a cell line named ssf-MDCK, which was amenable for single-cell suspension culture in the serum-free medium. We found that during serum-free batch culture of MDCK cells, the peak viable cell density and maximum specific growth rate were 3.81 x 10(6) cells/mL and 0.056 h(-1), respectively; 3.6- and 1.6-fold increase compared with those in serum-containing adherent batch culture. In addition, we compared growth and metabolic characteristics of MDCK cells in serum-containing adherent culture, serum-free adherent culture and serum-free single-cell suspension culture. We found that less metabolic by-products were produced in both serum-free cultures. In serum-free single-cell suspension batch culture, the viable cell density was highest. These results are critical for establishing large-scale suspension culture of MDCK cells as subsequent well as large-scale influenza vaccine production.

Correlation between renal function and arterial stiffness of Uighur population over 35 years in Xinjiang area / 中华肾脏病杂志

Objective To study the correlation between renal function and arterial stiffness of Uighur population over 35 years old in Xinjiang area. Methods From October 2007 to March 2010, four-stage stratified random sampling method was applied to collect a total of 4312 Uighur people over 35 years old in Urumqi, Karamay, Fukang, Turpan area, Hotan prefecture, Yili Kazak autonomous prefecture and Altai prefecture. The data of these 4312 general urban and rural Uygur residents were complete. Simplified MDRD formula was used to calculate the estimate glomerular filtration rate (eGFR). Arm-ankle pulse wave velocity (b-aPWV) of both sides was measured and the average value was used in correlation analysis with eCFR, and then the associated risk factors were adjusted. Results The eGFR was negatively correlated with b-aPWV (r=-0.174, P<0.01). Multiple linear regression showed that after adjusting some risk factors such as age, sex, body mass index, systolic blood pressure, diastolic blood pressure, waist circumference, hip circumference, uric acid, fasting blood glucose, total cholesterol, triglycerides, low density lipoprotein, eGFR was still negatively correlated with b-aPWV (P=0.012). Conclusions In Uygur population over 35 years old in Xinjiang, the glomerular filtration rate is negatively correlated with arterial stiffness.

Methods Data was from the investigation of cardiovascular risk survey (CRS) program among different nationalities in Xinjiang from October 2007 to March 2010. A total of 14 618 samples aged over 35 with complete data dimension were surveyed. Results ( 1 ) There were 633 patients with stroke, including 258 Hans (4.48%), 247 Uighurs (5.18%), and 128 Kazakhs (3.13%). The incidence of stroke was significant different in the three ethnic groups (P＜0.001). (2)Compared to the Han population, the incidence of stroke was higher ( OR= 1.304) in Uighur but lower (OR=0.794) in Kazakh. (3) PWV was significant different between stroke and non-stroke patients. After adjustment for age, body mass index, systolic blood pressure, triglyceride, total cholesterol and other risk factors, the difference remained significant, indicating that PWV (OR=1.001, P＜0.001) might associate with the occurrence of stroke. Conclusion The results of this study showed that the incidence of stroke was significantly different in the three ethnic groups. PWV might associate with the occurrence of stroke.

Surgical intervention and radiotherapy outcome of solitary plasmacytoma of cervical spine / 中华外科杂志

<p><b>OBJECTIVE</b>To study the clinical features, treatment methods and outcome of solitary plasmacytoma of cervical spine.</p><p><b>METHODS</b>From January 1995 to December 2007, the data of 23 cases with solitary plasmacytoma of cervical spine was analyzed. There were 16 males and 7 females (mean age 56 years, range: 32 - 76 years). Two cases underwent radiotherapy alone and 21 patients received surgery. According to WBB staging system, surgical procedures were defined as total or subtotal resection (6 cases), appendix resection (4 cases), sagittal resection (3 cases) and total spondylectomy (8 cases). All surgical cases were managed using an anterior approach, posterior approach or combined anterior and posterior approach. The cervical spinal reconstruction was achieved through anterior cervical titanium plate and titanium mesh cage filled with auto iliac graft or bone cement, or anterior and posterior combined instrumented fusion. All patients received radiotherapy as adjunctive therapy.</p><p><b>RESULTS</b>Follow-up of the 23 cases lasted 24.0 - 143.0 months (mean: 64.7 months). Neck pains obviously improved, and nerve compression symptoms disappeared or improved after surgery. Neurological function improved by 1 - 2 grades based on Frankel grading system. All the internal fixations were fused well and stability of the cervical spine was fine and no spine instability could be seen in our series. The bone graft fusion rate was 100%. During the follow-up period, 6 surgical cases had local recurrence and finally progressed to multiple myeloma (MM) and 3 died. Two cases without surgical treatment progressed to MM in 1 year and 1.5 years after confirmed diagnosis. They were given systemic chemotherapy. The other 15 patients had disease-free survival and after surgery and adjunctive radiotherapy. Obvious abnormity were not found in such examinations as M protein, bone marrow aspiration and emission computed tomography or PET-CT examinations.</p><p><b>CONCLUSIONS</b>Solitary plasmacytoma of cervical spine is rarely seen clinically. Surgery is recommended as the primary management for patients with overt bone destruction and spinal instability or neurological dysfunction. Tumor excision with adjunctive radiotherapy can obviously reduce local recurrences and lower the possibility of progression to MM. The patients with progression to MM should receive chemotherapy according to chemotherapy protocol while the prognosis is comparatively worse.</p>

The pulmonary transvalvular gradient (PTG) was (86.4 +/- 33.6) mm Hg(1 mm Hg = 0.133 kPa) and the right ventricular systolic pressure was (107.5 +/- 36.5) mm Hg before PBPV. Single-balloon valvuloplasty was performed in 41 patients, double-balloon valvuloplasty in 6 patients and Inoue-balloon valvuloplasty in 18 patients. The ratio of balloon/valve ranged from 1.00 to 1.19 in 19 patients, from 1.20 to 1.39 in 42 patients, and greater than 1.40 in 4 patients. The procedure was classified as successful when the RV-PA gradient was < 36 mm Hg post procedure, 6 to 12 months follow up was finished after PBPV by catheterization or echocardiography in 25 patients. Immediate post procedure success rate was 81.5% (53/65). The lowest PTG immediately post procedure was seen in Inoue balloon group and balloon/valve ratio between 1.20 to 1.39 group. Post procedure, tricuspid valve regurgitation was evidenced in 2 patients, reactive right ventricular outflow tract stenosis was shown in 26 patients (13 from Inoue group) and pulmonary regurgitation was detected in 3 patients. The mean PTG was (35.7 +/- 23.9) mm Hg at follow-up. PTG gradually reduced to normal in 6 patients with post procedure PTG > or = 36 mm Hg. Right ventricular outflow tract stenosis was attenuated in all 11 followuped patients. There was no restenosis during follow-up.</p><p><b>CONCLUSION</b>Percutaneous balloon valvuloplasty was effective and safe for treating patients with pulmonary valve stenosis. Superior outcome was linked with balloon/valve ratio between 1.20 to 1.39 and Inoue balloon valvuloplasty in this cohort.</p>

DAPT enhances the apoptosis of human tongue carcinoma cells / 国际口腔科学杂志·英文版

<p><b>AIM</b>To investigate the effect of DAPT (gamma-secretase inhibitor) on the growth of human tongue carcinoma cells and to determine the molecular mechanism to enable the potential application of DAPT to the treatment of tongue carcinoma.</p><p><b>METHODOLOGY</b>Human tongue carcinoma Tca8113 cells were cultured with DAPT. Cell growth was determined using Indigotic Reduction method. The cell cycle and apoptosis were analyzed by flow cytometry. Real-time PCR and Immuno-Fluorescence (IF) were employed to determine the intracellular expression levels.</p><p><b>RESULTS</b>DAPT inhibited the growth of human tongue carcinoma Tca8113 cells by inducing G0-G1 cell cycle arrest and apoptosis. The mRNA levels of Hairy/Enhancer of Split-1 (Hes-1), a target of Notch activation, were reduced by DAPT in a dose-dependent manner. Coincident with this observation, DAPT induced a dose-dependent promotion of constitutive Caspase-3 in Tca8113 cells.</p><p><b>CONCLUSION</b>DAPT may have a therapeutic value for human tongue carcinoma. Moreover, the effects of DAPT in tumor inhibition may arise partly via the modulation of Notch-1 and Caspase-3.</p>
