OBJECTIVETo study the blood enriching effects of Paeoniae Radix Rubra and Paeoniae Radix Alba, paeoniflorin and albiflorin on mouse model of blood deficiency caused by γ-ray radiation.

METHODBuild mouse model of blood deficiency induced by γ-ray radiation. Paeoniae Radix Rubra and Paeoniae Radix Alba were given during modeling. The amount of WBC was detected af- ter the treatment. Based on the result of WBC and paeoniflorin content, albiflorin content in Paeoniae Radix Rubra and Paeoniae Radix Alba, the same model and the same method were used to comparatively study the effect of blood enriching of paeoniflorin and albiflorin.

RESULTOn the 7th day, the amount of WBC in model mice treated with 2 g x kg(-1) Paeoniae Radix Alba and 2 g x kg(-1) Paeoniae Radix Rubra significantly increased compared with that of model group (P < 0.05). In another experiment with the same model, the amount of WBC in model mice treated with 120 mg x kg(-1) paeoflorin and 120 mg x kg(-1) albiflorin significantly increased (P < 0.05) compared with that of model group on the 7th day. On the 10th day, the amount of WBC in rats treated with 120 mg x kg(-1) paeoflorin increased significantly (P < 0.05) compared with that of model group. Compared with the same dose of paeoniflorin, the amount of WBC in mice treated with albiflorin had no significant difference.

CONCLUSIONAll Paeoniae Radix Alba, Paeoniae Radix Rubra, paeoniflorin and al- biflorin can raise the amount of WBC and have the effect of enriching blood induced by radiation, while paeoniflorin and albiflorin have a similar result in this model. The result indicated that both paeoniflorin and albiflorin are effective constituents in Paeoniae Radix Alba, and paeoniflorin work as the common effective constituent in both Paeoniae Radix Rubra and Paeoniae Radix Alba.

BACKGROUND: Angiotensinogen (AGT) gene is the firstly discovered candidate gene for essential hypertension, both the T174M and M235T polymorphisms locate at the second exons of AGT gene, and there is existence of linkage disequilibrium. 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.

BACKGROUND:Mimics software is a three-dimensional (3D) image processing and editing tool based on CT scan data. Mimics software can rebuild the data and images gotten in CT, MRI and ultrasound scans into 3D images and display on the computer screen so as to help clinicians understand the type of fracture and the relationship of the 3D structure of the surrounding tissue and to provide a great help in the development of orthopedics operation. OBJECTIVE:To explore the application effect of Mimics software 3D reconstruction on perioperative period of Pilon fracture. METHODS:This study selected 61 cases of Pilon fracture, who received the surgery in the Zhongshan City Xiaolan People’s Hospital from September 2008 to September 2013, as research objects. They were randomly divided into 3D group and control group in accordance with the time of admission. Al patients underwent anterioposterior and lateral X-ray film examination and multi-slice spiral CT scan. Patients in the control group received internal fixation according to above examination results. Patients of the 3D group, on the base of those of the control group, were subjected to internal fixation after three-dimensional entity reconstruction by using Mimics V 10.0 software. Operation time and functional curative effect in the postoperative folow-up were compared between the two groups. RESULTS AND CONCLUSION:The operation time was significantly less in the 3D group than in the control group (P < 0.05). The number of patients with excelent 6-month functional curative effect was more, and the number of patients with poor effect was less in the 3D group than in the control group. The 6-month functional curative effect was better in the 3D group than in the control group (P < 0.05). These results showed that the application of Mimics software 3D reconstruction to the perioperative period of Pilon fractures can give comprehensive assessment of the situation of fracture, optimize and improve the preoperative plan and reduce the risk of surgery, and promote the successful completion of internal fixation.
