OBJECTIVE: To observe the effects on neural function, living ability and mental state of the patients with acute intracerebral hemorrhage (ICH), as well as aquaporin 4 (AQP4) in the serum after treated with electroacupuncture (EA) on the base of routine therapy of western medicine. METHODS: Seventy-two acute ICH patients were randomized into an observation group (36 cases, 4 cases dropped off) and a control group (36 cases, 2 cases dropped off). In the control group, the conventional treatment was delivered such as stopping bleeding, preventing re-hemorrhage, controlling blood pressure, mitigating neural edema and reducing intracranial pressure. In the observation group, on the base of the treatment in the control group, EA was supplemented. Acupoints included Shuigou (GV 26), bilateral Neiguan (PC 6) and Sanyinjiao (SP 6) etc. Electric stimulation was operated at Neiguan (PC 6) and Sanyinjiao (SP 6) on the same side, with disperse-dense wave, and 2 Hz/100 Hz in frequency, tolerable current intensity. Electric stimulation was delivered for 30 min in each treatment, once daily and for 6 times per week. The duration of treatment was 2 weeks in the two groups. Before and after treatment, changes of the scores of National Institutes of Health stroke scale (NIHSS), modified Barthel index (MBI) and mini-mental state examination (MMSE), as well as AQP4 content in the serum were observed in the two groups; the efficacy and safety were compared between the two groups. RESULTS: The NIHSS scores and the serum AQP4 content decreased after treatment when compared with those before treatment in the two groups (P<0.05), while, MBI and MMSE scores increased (P<0.05). In the observation group, NIHSS score and serum AQP4 content were lower than those of the control group (P<0.05), and MBI and MMSE scores were higher (P<0.05). The total effective rate of the observation group was 93.8% (30/32), higher than that of the control group (73.5%, 25/34, P<0.05). The treatment in the two groups was safe, without adverse reactions and events occurring in the patients. CONCLUSION Electroacupuncture, on the base of conventional treatment of western medicine, can effectively improve the neural function, living ability, mental state and serum AQP4 content of the patients with acute ICH. It is suggested that the effective treatment by electroacupuncture may be related to the regulation of the serum AQP4 content.

Objective To explore the relationship between self-reported chronic disease and smoking behavior among adult males in Jiangsu Province. Methods In 2007, 2010, and 2013 respectively, a multistage stratified cluster sampling method was used to select residents from 14 adult chronic diseases and their risk factor surveillance sites in Jiangsu Province to investigate the relationship between the prevalence of chronic diseases, smoking and smoking cessation behaviors among men aged 18 to 69 years. Results A total of 8 313 men aged 18 to 69 years had a self-reported prevalence of 1.5%, 1.1%, 1.5%, and 2.8% for cardiovascular and cerebrovascular diseases, malignancies, asthma, and chronic obstructive pulmonary disease (COPD), respectively.The self-reported prevalence of all four chronic diseases was higher in ex-smokers than in current smokers and non-smokers (all P<0.05).Multivariate analysis showed that the quit rate was of those suffering from cardiovascular and cerebrovascular diseases, malignancies, asthma, and COPD, respectively 3.356 times (95% CI: 1.966-5.728), 3.864 times (95% CI: 2.277-6.555), 2.103 times (95% CI: 1.321-3.345), and 2.586 times (95% CI: 1.872-3.573) higher, than those without. Conclusion Smoking cessation rates were significantly higher of those with chronic disease than those without, suggesting that illness would promote smoking cessation behaviors among smokers.

PURPOSE: Conditional survival (CS) provides important information on survival for a period of time after diagnosis. Currently, information on CS patterns of patients with nasopharyngeal carcinoma (NPC) is lacking. We aimed to analyze survival rate over time and estimate CS for NPC patients using a national population-based registry. MATERIALS AND METHODS: Patients diagnosed with NPC between 1973 and 2007 with at least 5-year follow-up were identified from the Surveillance Epidemiology End Results registry. Traditional survival rates and crude CS estimateswere calculated using Kaplan-Meier analysis. Risk-adjusted survival curves were plotted from the proportional hazards model using the correct group prognosis method. RESULTS: For 7,713 patients analyzed, adjusted baseline 5-year overall survival improved significantly from 36.0% in patients diagnosed in 1973-1979, 41.7% in 1980-1989, 46.6% in 1990-1999, to 54.7% in 2000-2007 (p < 0.01). CS analysis demonstrated that for every additional year survived, adjusted probability of surviving the next 5 years increased from 66.7% (localized), 54.0% (regional), and 35.3% (distant) at the time of diagnosis, to 83.7% (localized), 75.0% (regional), and 62.2% (distant) for patients who had survived 5 years. Adjusted 5-year CS differed among age, sex, tumor histology, ethnicity, and stage subgroups initially, but converged with time. CONCLUSION: Treatment outcomes of NPC patients have greatly improved over the decades. Increases in CS become more prominent in patients with distant disease than in those with localized or regional disease as patients survive longer. CS provides more dynamic prognostic information for patients who have survived a period of time after diagnosis.

Objective: To discriminate traditional She medicine Gegongniugen (the root of Rubus chingii Hu) from its confusable species of genus Rubus based on ITS2 barcode, and to guarantee the medicine quality and clinical effect of Gegongniugen. Methods: A total of 140 samples of R. corchorifolius L. f., R. hirsutus Thunb., R. parvifolius L., R. coreanus Miq., R. buergeri Miq., R.tsangorum Hand. -Mazz., R. trianthus Focke, R. jiangxiensis Z. X. Yu, W. T. Ji et H. Zheng were collected from Zhejiang, Guangxi, Jiangxi, and Anhui provinces. Genomic DNA was extracted from the collected samples, followed by ITS2 sequences amplification through PCR, bi-directional sequencing, assembly and annotation based on HMMer method. At the same time, 37 other sequences of corresponding species were downloaded from GenBank. Sequence characteristics such as lengths, GC contents, and variable sites were analyzed by Gene Tool software while genetic distance calculation and build-up of neighbor-joining (NJ) phylogenetic tree were carried out through Clustal X and MEGA 7.0. Results: The lengths of ITS2 sequences of Gegongniugen and its nine confusable species of genus Rubus ranged from 211 to 213 bp with GC content of 52.1%-58.0%; These ITS2 sequences had 14 mutation sites and one insertion/deletion site; The average intra-specific K2P genetic distance of Gegongniugen was 0.007 2, which was significantly lower than the respective inter-specific K2P genetic distance between Gegongniugen and its confusable species of genus Rubus. The genetic distantes between Gegongniugen and R. corchorifolius or Gegongniugen and R. jiangxiensis were minimum, while that between Gegongniugen and R. hirsutus was maxmum. It was obvious in the N-J phylogenetic tree that the ITS2 sequences of Gegongniugen formed into one separate clade, which could be successfully distinguished other nine species. Conclusion: ITS2 sequence can be used as an effective DNA marker to discriminate the original plants of Gegongniugen and its confusable species of genus Rubus, which provided an important molecular evidence for the identification of traditional She medicines and contributed to the information supervision of traditional She medicine market.

OBJECTIVE: To explored whether adipose derived stem cells (ASCs) could inhibit the pro-liferation of peripheral blood mononuclear cells (PBMCs) and whether inflammatory priming could enhance this property of ASCs. METHODS: We isolated ASCs using collagenase from adipose tissue and expanded them in vitro. Cells were induced to differentiate into adipogenic and osteogenic lineages. The cells at passage 3 to passage 5 were used for the experiments. After carboxy fluoresce in succinimidyl ester (CFSE) staining, PBMCs were co-cultured with inflammatory priming ASCs. The PBMCs cultured without ASCs or with non-treated ASCs defined as control groups. Then we used flow cytometry to detect the proliferation of PBMCs. RESULTS: ASCs had fibroblast-like phenotype and were spindle shaped. They were able to differentiate into cells of adipogenic and osteogenic lineages in specific induction media. ASCs had the CD expression profile consistant with the International Federation for Adipose Therapeutics statement. The percentage of parent cells in PBMC after co-cultured with ASCs increased, though there was no statistical significance. However, when co-cultured with inflammatory priming ASCs, the percentage of parent cells significantly increased (with inflammatory priming ASCs group vs. without ASCs group, 38.7%±10.0% vs. 28.4%±8.9%, P<0.05). This indicated that inflammatory priming ASCs could significantly inhibit the proliferation of PBMCs. CONCLUSION Inflammatory cytokines can enhance the immunosuppressive ability of ASCs. Our findings may help the application of ASCs in tissue repairment with better results.

Shexiang Baoxin pill(SBP) is widely used for treating coronary heart disease in clinic, with ginsenosides as its main effective component. This study was designed to investigate and compare the pharmacokinetic characteristics of five ginsenosides of five compounds after multiple oral administrations, ginseng extract(GE) and SBP in myocardial infarction rats. After intragastric administration to myocardial infarction rats, the plasma samples were analyzed by liquid chromatography tandem triple-quad mass spectrometry. The results showed that Cmax of five compounds in all groups were less than 200 μg•L⁻¹. Tmax of corresponding analytes between groups revealed that ginsenosides in both SBP and GE were absorbed faster than each of the five compounds, indicating that GE and compounds contain components promoting absorption of ginsenosides. The oral administration doses of ginsenosides in SBP were the least in all groups, but with the greatest AUC0-tand AUCINF, which indicated that ginsenosides in SBP had the best absorption in all groups after oral administration to myocardial infarction rats. This study also demonstrated that compound is the best form of traditional Chinese medicine.

Objective To investigate the efficacy of an anti-vascular endothelial growth factor (VEGF) antibody,MIL60,in inhibiting corneal neovascularization (CoNV) formation in a rat model of alkali cauterization and its involved mechanisms.Methods Rat CoNV model induced by alkali burn was founded in the right eyes,and then 72 cases were randomly divided into four groups according to the subconjunctival administration of medicine next day after the successful establishment of this model:25mg· mL-1 MIL60 group,dexamethasone group,MIL60 solvent group and NaCl group.Then CoNV was observed for recording the its length and the involved area using digital photograph.Next the rats were sacrificed on day 7,14,21 and 28,followed by the collection of rats' cornea for HE and immunohistochemical staining to analyze the protein expression of VEGF,VEGF receptor-1 (VEGFR-1),VEGFR-2 and matrix metallopeptidase-9 (MMP-9).Results At each time point,the area and length of CoNV in the 25 mg· mL-1 MIL60 and dexamethasone group were significantly less than those in the MIL60 solvent and NaC1 group,and the differences were statistically significant (all P ＜0.01),and 25 mg· mL-1 MIL60 group had the similar CoNV area and length with the dexamethasone group (all P ＞ 0.05).Moreover,HE and immunohistochemical staining showed that MIL60 could inhibit the protein expression of VEGF,VEGFR-1,VEGFR-2 and MMP-9,which could explain its effective anti-angiogenic activity.Conclusion Subconjunctival administration of MIL60 can significantly inhibit corneal neovascularization formation and alleviate the inflammation in rats suffered from alkali burn.

BACKGROUND:The angiogenesis may be related to the proliferation of neural stem ceils,but there is still no unified view.OBJECTIVE:To observe the influence of angiogenesis on neural stem cell proliferation in the subventricular zone of rats after focal cerebral ischemia/reperfusion.METHODS:Male Sprague-Dawley rats were randomly divided into normal group,sham group,vascular endothelial growth factor (VEGF)+cerebral ischemia/reperfusion group,normal saline (NS)+cerebral ischemia/reperfusion group.The injection was done via the lateral cerebral ventricle.Then,each group was subdivided into four groups (1,2,7,14 days after ischemia/reperfusion).Focal cerebral ischemia/reperfusion models were made by the thread method.After modeling,the corresponding intervention was given in each group.The expression changes of Nestin and vWF mRNA in the subventricular zone were detected in all groups by immunohistochemical staining and real-time PCR,respectively.RESULTS AND CONCLUSION:There was a certain increase in vWF and Nestin positive expression in the subventricular zone after cerebral ischemia/reperfusion.At 7 days after ischemia,the expression of vWF mRNA and Nestin reached the peak,indicating the proliferation of neural stem cells in the subventricular zone after cerebral ischemia/reperfusion is associated with the time of angiogenesis.In addition,the expression of vWF mRNA and Nestin was significantly higher in the VEGF+cerebral ischemia/reperfusion group than the other two groups,indicating angiogenesis could promote the proliferation of neural stem ceils in the subventricular zone of rats after cerebral ischemia/reperfusion.

Insulin resistance is the pathophysiological basis of many diseases. Overcoming early insulin resistance highly significant in prevention diabetes, non-alcoholic fatty liver, and atherosclerosis. The present study aimed at evaluating the therapeutic effects of baicalin on insulin resistance and skeletal muscle ectopic fat storage in high fat diet-induced mice, and exploring the potential molecular mechanisms. Insulin resistance in mice was induced with a high fat diet for 16 weeks. Animals were then treated with three different doses of baicalin (100, 200, and 400 mg·kg(-1)·d(-1)) for 14 weeks. Fasting blood glucose, fasting serum insulin, glucose tolerance test (GTT), insulin tolerance test (ITT), and skeletal muscle lipid deposition were measured. Additionally, the AMP-activated protein kinase/acetyl-CoA carboxylase and protein kinase B/Glycogen synthase kinase 3 beta pathways in skeletal muscle were further evaluated. Baicalin significantly reduced the levels of fasting blood glucose and fasting serum insulin and attenuated high fat diet induced glucose tolerance and insulin tolerance. Moreover, insulin resistance was significantly reversed. Pathological analysis revealed baicalin dose-dependently decreased the degree of the ectopic fat storage in skeletal muscle. The properties of baicalin were mediated, at least in part, by inhibition of the AMPK/ACC pathway, a key regulator of de novo lipogenesis and activation of the Akt/GSK-3β pathway, a key regulator of Glycogen synthesis. These data suggest that baicalin, at dose up to 400 mg·kg(-1)·d(-1), is safe and able to attenuate insulin resistance and skeletal muscle ectopic fat storage, through modulating the skeletal muscle AMPK/ACC pathway and Akt/GSK-3β pathway.

In this study, pEGFP-N1 was chosen as the reporter plasmid and transferred into Ctenopharyngodon idellus kidney (CIK) cells by electroporation, and the optimal electroporation conditions were determined by testing the transfection efficiency with different voltages, pulse times, plasmid amounts, and numbers of shocks. The results showed that the maximum electroporation efficiency was achieved under the following conditions in a 0.2 cm electroporation cuvette containing CIK cells (1.5 x 10(7)/mL, 200 microl): electric voltage 200 V, pulse time 45 ms, plasmid 30 microg, and one electric shock. The total genomic RNA of grass carp reovirus (GCRV) was extracted in this experiment and reversely transcribed into cDNA, which was used to amplify the gene segment of GCRV non-structural protein NS26 using designed specific primers. The PCR product was recombined into pEGFP-N1 vector. The fusion protein EGFP-NS26 was successfully and efficiently expressed in the CIK cells by electroporation, which was confirmed by both fluorescent imaging and Western blot analysis. This experiment laid a foundation for further functional studies of the non-structural protein NS26 of GCRV.
