Objective:To evaluate the effects of endovascular embolization and microsurgical clipping on cognitive function in patients with intracranial aneurysm.Methods:A total of 80 patients with intracranial aneurysms,who were treated in Chongqing Hospital of Traditional Chinese Medicine from March 2014 to September 2015,were selected and randomly divided into control group(n=40) and experimental group (n=40).The control group was treated with microsurgical clipping,and the experimental group,with endovascular embolization.The postoperative cognitive function was assessed by the mini mental state examination scale (MMSE),and length of stay,in-hospital mortality rate,mortality rate in 1 year and the incidence of postoperative adverse reactions were compared between the two groups.Results:The total score (26.78± 0.85) of MMSE in the experimental group was higher than that (22.25± 0.63) of the control group (P＜0.05).The cognitive dysfunction rate (37.50％) of the experimental group was lower than that (55.00％) of the control group (P＜0.05).The length of stay [(6.7± 3.9) days] of the experimental group was lower than that [(9.6± 4.5) days] of the control group(P＜0.05).There were no significant differences in in-hospital mortality rate and mortality rate in 1 year,and the incidence of adverse reactions between the two groups (P＞0.05).Conclusion:Endovascular interventional therapy can improve the cognitive function of the patients with intracranial aneurysms and shorten the length of hospital stay.

Cerebral apoplexy is one of the main causes of death in the middle-aged and elderly population,which has higher mortality and disability rate.The incidence of the disease is increasing year by year and it is a serious threat to human life and health.Therefore,it is of great significance to find an effective target for the diagnosis and treatment of stroke.Thioredoxin (Trx) is the major thiol reducing agent in the cells,it is involved in many signal transduction pathways in the cells by regulating the redox state of the cell.It has disulphide reductase activity,which can reduce the oxidative stress injury in the rats after the stroke.Thioredoxin interacting protein (TXNIP) is an endogenous inhibitor of Trx,it can destroy the redox balance and promote the oxidative stress by binding/inhibiting the activity of Trx,while the inhibition or knockdown of TXNIP has obvious neuroprotective effects.Recent studies suggest that Trx/TXNIP may be involved in the pathophysiology of cerebral apoplexy by a variety of pathways.This article analyses the research status of Trx/TXNIP and studies the localization of Trx system in the central nervous system and the progress of Trx system in ischemic cerebral apoplexy.It reviews the mechanism of Trx/TXNIP in cerebral apoplexy and prospectes the signaling pathways involved in the pathophysiological process of Trx/TXNIP to provide new ideas for the treatment of cerebral apoplexy.

The clinical value of whole body positron emission tomography/computed tomography (PET/CT) as an imaging tool in diagnosis of ophthalmic tumors was investigated.The retrospective observational case series were performed on the patients with suspected ophthalmic tumors who underwent whole body PET/CT.The golden standard of diagnosis was the final pathological diagnosis or the results of long-term follow-up for patients without surgery/ biopsy.PET/CT findings were compared with the golden standard.The sensitivity,specificity,accuracy and positive likelihood ratio of PET/CT in the detection of ophthalmic tumors were calculated.The clinical application of PET/CT in different types of ophthalmic tumors was evaluated.The results showed that 30 patients (18 males and 12 females) with a mean age of 43.0 years (range 4-63 years) were collected.The mean sizes of orbital tumors and intraocular tumors were 26.8 mm×17.8 mm and 11.2 mm×6.1 mm,respectively.The overall sensitivity,specificity,accuracy and positive likelihood ratio of whole body PET/CT in ophthalmic tumors were 76.5％,71.4％,75.0％ and 2.67,and were 62.5％,100％ and 70.0％ in intraocular tumors,and those were 100％,60.0％ and 84.6％ in orbital tumors,respectively.PET/CT findings were applied to help make appropriate treatment options in 27 out of 30 patients (90.0％),and 12 (40.0％) patients changed the treatment strategy.False negative results in 4 cases and false positive results in 2 cases were observed in this series.It was suggested that PET/CT was an effective imaging modality in detecting,diagnosing and developing therapeutic schedule for patients with ophthalmic tumors.It was more sensitive and accurate for detecting orbital tumors than for detecting intraocular tumors.

The polymorphism at A-6G and G-217A sites in promotor region plays an important role in regulating the gene expression, and the products of keep close correlation with the level of blood pressure. OBJECTIVE: To investigate the association between the polymorphism of AGT gene at A-6G, T174M and G-217A sites and the risk for the attack of essential hypertension in Chinese Han population, DESIGN: A cluster sampling and case-control analysis. SETTINGS: Department of Geriatrics and Department of Cardiology, the First Affiliated Hospital of Nanjing Medical University; Southern Research Center of National Human genome; Department of Cardiology, Dongtai People's Hospital of Jiangsu Province. PARTICIPANTS: The experiment was carried out in the countryside of Dongtai county, Yancheng city, Jiangsu province. All the subjects were selected from the countryside of Dongtai county, Yancheng city, Jiangsu province. Totally 177 patients with essential hypertension who had never accepted any drug treatment, were taken as the essential hypertension group, and hypertension was diagnosed according to the diagnostic standard of hypertension set by WHO/ISH in 1999 (systolic blood pressure ≥ 140 mm Hg and/or diastolic blood pressure ≥ 90 mm Hg); Another 86 normal person were taken as the normal control group. ② Inclusive criteria: The enrolled subjects should be Han nationality; long-term local residents but not from other places; able to answer questions clearly; diagnosed by disease history, clinical symptoms, physical signs and assistant examinations; have complete data of investigation of uniform questionnaires by face-to-face interview (including demographic information, profession history, family history and life styles of smoking, drinking, drinking tea, etc.). ③ Exclusive criteria: The patients with secondary hypertension in the essential hypertension group, subjects having family hisory of hypertension in the normal control group, and those with chronic diseases of liver and kidney, and diabetes mellitus in both groups were excluded. METHODS: Peripheral venous blood samples (3 mL) were collected, and DNA was extracted from human peripheral blood with FlexiGene DNA Kit (250). The Primer3 software was applied to design primers, and the polymorphism sites in the primer sequence were excluded. After multiplex polymerase chain reaction (PCR), 3 μL products were selected to detected the amplified results by agarose gel electrophoresis. The successfully amplified PCR products were purified with the QIAquick PCR Purification Kit, and the purified products were fragmentized with Dnase Ⅰ . The fragmentized products of enzyme digestion were labeled with fluorescein by deoxynucleotide terminal transferase. Two allele specific probes and one mismatched probe were designed respectively for each single nucleotide polymorphism. The chips were prepared with the OmniGridTM 100 TLC samler, each probe was repeated for three times to form three matrix. The hyridization solution was degenerated at 95 ℃ for 10 minutes, and then immediately cut on ice. 10 μL hybridization solution was added onto the chip matrix, hybridized at 50 ℃ for 2 hours, then washed and dried. The chips were scanned with the GenePix 4000B laser confocal scanner (Figure 2),and the intensity of the fluorescent signal for each probe was extracted with GenePix Pro, and the allele score of each single nucleotide polymorphism was calculated to judge the genotype. MAIN OUTCOME MEASURES: ① Comparison of the frequencies of genotype distribution at each polymorphism site of AGT gene in both groups; ② Correlation analysis of the polymorphism of AGT gene at A-6G and T-174M sites with the risk for the attack of essential hypertension; ③ Effects of the polymorphism of AGT gene at A-6G, T-174M and G-217A sites on blood pressure.RESULTS: According to the intention-to-treat analysis,all the 263 subjects were involved in the analysis of results. ① At the A-6G site of AGT gene, the frequencies of AA, AG and GG genotypes (P=0.014) and A and G alleles (P=0.004, OR=0.44) had significant differences between the essential hypertension group and normal control group; At the T174M site, the frequencies of CC, CT and TT genotypes (P=0.031) and A and G alleles (P=0.014, OR=0.55) were significantly different; At the G-217A site, no obvious differences were found in the GG, AG and AA genotypes (P=0.722) and G and A alleles (P=0.403, OR=0.80). ② The risk of essential hypertension in the individuals carrying AA genotype of A-6G polymorphism and CC genotype of T174M polymorphism was reduced by 57% (95%CI= 0.23-0.82, P= 0.010) and 56% (95%CI= 0.25-0.79, P= 0.006) respectively. ③ There were no significant differences in the systolic blood pressure, diastolic blood pressure and mean arterial pressure among different genotypes at the A-6G, T174M sites and G-217A sites (F=0.100- 2.911, P ＞ 0.05). CONCLUSION: The AA genope at A-6G and the CC genotype at T174M site of AGT gene may reduce the risk for the attack of essential hypertension in Chinese Hun population, and no significant correlation was found between the genotype of G-217A polymorphism and the attack of essential hypertension.

The paper aimed to evaluate the effects of lead stress on photosynthetic performance and ginsenoside content in ginseng (Panax ginseng). To accomplish this, three years old ginseng were cultivated in pot and in phytotron with different concentrations of lead, ranging from 0 to 1000 mg x kg(-1) soil for a whole growth period (about 150 days). The photosynthetic parameters in leaves and ginsenoside content in roots of ginseng were determined in green fruit stage and before withering stage, respectively. In comparison with the control, net photosynthetic rate and SPAD value in ginseng leaves cultivated with 100 and 250 mg x kg(-1) of lead changed insignificantly, however, ginseng supplied with 500 and 1 000 mg x kg(-1) of lead showed a noticeably decline in the net rate of photosynthesis and SPAD value (P < 0.05), the lowest net photosynthetic rate and SPAD value showed in the treatment supplied with 1 000 mg x kg(-1) of lead, with decline of 57.8%,11.0%, respectively. Total content of ginsenoside in ginseng roots cultivated with 100 mg x kg(-1) of lead showed insignificantly change compared to the control, but the content increased remarkably in treatments supplied with 250, 500, 1 000 mg x kg(-1) of lead (P < 0.05), and highest content appeared in these ginsengs exposed to 1000 mg x kg(-1) of lead. The net photosynthetic rate and SPAD value in leaves of ginseng both showed significantly negative linear correlations with lead stress level (P < 0.01), and significant positive linear correlations between total content of ginsenoside and lead concentration was also observed (P < 0.05). These results strongly indicate that exposing to high level of lead negatively affects photosynthetic performance in ginseng leaves, but benefits for accumulation of secondary metabolism (total content of ginsenoside) in ginseng root.

Objective:To construct a novel biomimetic calcium phosphate (BioCaP) scaffold loaded with bone morphogenetic protein-2 (BMP-2),and to investigate its role in the osteogenesis of human adipose-derived stem cells (hASCs) in vitro and in vivo.Methods:The BioCaP scaffold coprecipitated with BMP-2 (BMP-2-BioCaP) was constructed in this study.Field emission scanning electron microscopy (SEM) was used to analyze the morphology of the surfaces.The release kinetics was measured to evaluate the slow-release characteristics in vitro.BMP-2-BioCaP was immersed in proliferation medium (PM) or osteogenic medium (OM),respectively.The supernatants were collected and used to culture hASCs in vitro.Cell numbers were determined using the cell-counting kit-8 (CCK-8) to assess the cell proliferation.After 7 and 14 days,alkaline phosphatase (ALP) staining and quantification were performed to test the activity of ALP.After 14 and 21 days,the calcification deposition was determined by alizarin red S (ARS) staining and quantification.The expressions of the osteoblast-related genes were tested on day 4 and day 14.In the in vivo study,6 nude mice were used and implanted subcutaneously into the back of the nude mice for 4 groups:(1) BioCaP scaffold only,(2) BioCaP scaffold + hASCs,(3) BMP-2-BioCaP scaffold,(4) BMP-2-BioCaP scaffold + hASCs (test group).After 4 weeks of implantation,hematoxylin-eosin (HE) staining was performed to evaluate the in vivo osteogenesis of hASCs.Results:SEM observations showed that BioCaP and BMP-2-BioCaP scaffold were entirely composed of straight,plate-like and sharp-edged crystal units,and the length of the crystal units varied between 5 and 10 μm.Release kinetics analysis demonstrated that BMP-2 incorporated with BioCaP could be released at certain concentration and last for more than 21 days,and the accumulative protein release could reach 20％.CCK-8 assays showed that cell proliferation was not significantly affected by BMP-2BioCaP.ALP activity was higher by the induction of OM + BMP-2-BioCaP than of the other groups (P ＜0.01).More mineralization deposition and more expressions of osteoblast-related genes such as Runt-related transcription factor 2 (RUNX2),ALP,osteopontin (OPN) and osteocalcin (OC) were determined in the OM + BMP-2-BioCaP group at different time points (P ＜0.01).HE staining showed that,in the test group and BMP-2-BioCaP scaffold group,the extracellular matrix (ECM) with eosinophilic staining were observed around hASCs,and newly-formed bone-like tissues could be found in ECM around the scaffold materials.Moreover,compared with the BMP-2-BioCaP scaffold group,more bone-like tissues could be observed in ECM with typical structure of bone tissue in the test groups.No obvious positive results were found in the other groups.Conclusion:BMP-2-BioCaP scaffold could achieve slow-release of BMP-2 and promote the osteogenic differentiation of hASCs in vitro and in vivo.The novel tissue-engineered bone composed of hASCs and BMP-2-BioCaPis promising for the repair of bone defect.

The effects of Guizhi Fuling capsule and its active ingredient combination within different concentration on SPL proliferate were observed by MTT method. The ratio of CD80/86, CD3CD25 and CD3CD69 was used to evaluate cell activation effects of Guizhi Fuling capsule and its active ingredient combination by FCM. Guizhi Fuling capsule with concentration of 400 mg · L(-1)can promote spleen lymphocyte proliferation, as well as the active ingredient combination, which showed the obvious dose-effect relationship. Compared with control group, the difference has statistical significance (P≤0.01). The result of FCM showed that Guizhi Fuling capsule and its active ingredient combination can promote CD80 and CD86 expression on spleen lymphocyte, and also can increase CD25 and CD69 ratio between spleen CD3+ cells. Compared with control group, the difference has statistical significance (P≤0.01). Thus, Guizhi Fuling capsule and its active ingredient combination may have immune-modulate effects, and the mechanism may have a close relationship with the lymphocyte activation.
