Objective To observe the relationship between homocysteine (Hcy),C-reactive protein (CRP) and type 2 diabetes peripheral vascular disease (PVD).Methods Fifty-eight patients with type 2 diabetes according to the condition of PVD were divided into simple type 2 diabetes mellitus group (DM group,30 cases) and PVD group (28 cases).Twenty-five healthy people were chosen at the same period as control group.The fasting blood glucose (FBG),glycosylated hemoglobin (HbA1c),total cholesterol(TC),triglyceride (TG),high-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol (LDL-C),Hcy and CRP levels were detected among 3 groups,and the body mass index (BMI),ankle brachial index(ABI) was calculated.Results The BMI,TG,TC and HDL-C levels among 3 groups had no statistical significance (P ＞0.05).The FBG,HbA1c and LDL-C in DM group and PVD group were significantly higher than those in control group [(7.54 ± 1.25),(8.12 ± 1.57) mmol/L vs.(4.68 ±0.54)mmol/L; (6.92 ± 0.89)％,(7.54 ± 0.97)％ vs.(4.80 ± 0.54)％ ; (3.79 ± 0.73),(4.41 ± 0.93) mmol/L vs.(2.68 ± 0.54) mmol/L],and the difference was statistically significant (P ＜ 0.05).But the difference between PVD group and DM group had no statistical significance (P ＞ 0.05).Hcy and CRP in DM group and PVD group were higher than those in control group [(10.26 ± 3.62),(19.83 ± 5.54) μ mol/L vs.(8.92 ± 2.41)μ mol/L; (4.12 ±0.57),(5.47 ±0.85) mg/L vs.(2.73 ±0.54) mg/L],ABI was lower than that in control group(0.92 ± 0.18,0.81 ± 0.16 vs.1.02 ± 0.23),and the difference was statistically significant (P ＜ 0.05);Hcy,CRP in PVD group were obviously higher than those in DM group,ABI was lower than that in DM group,and the differences were statistically significant (P＜ 0.05).Spearman analysis showed that Hcy was negatively correlated with ABI (r =-0.635,P ＜ 0.05),CRP was negatively correlated with ABI (r =-0.529,P ＜ 0.05),and Hcy was positively correlated with CRP (r =0.528,P ＜ 0.05).The partial correlation analysis results showed that Hcy and ABI still showed a negative correlation (r =-0.315,P ＜ 0.05),CRP and ABI still showed a negative correlation (r =-0.243,P ＜ 0.05).Conclusion Hcy and CRP participating in the occurrence and development of type 2 diabetes PVD,can be used as a predictor of type 2 diabetes PVD.

Objective To explore the application value in primary hospitals using conventional ultrasound and ultrasonic elastography in the diagnosis and surgery of breast cancer both in the diagnosis of joint.Methods One hundred and sixteen patients with breast disease confirmed by surgical pathology were studied retrospectively .All the patients were examined by acoustic elastogra-phy and conventional ultrasonography before surgery.Results Pathological results of 116cases were:74 malignanies and 42 benigni-ties.①Preoperative routine ultrasonography in diagnosis of benign breast lesions in 41 cases, 65 cases of malignant lesions.Ultra-sonography showed that benign lesions were round or oval, smooth edge, no obvious signs of malignant microcalcifications, breast cancer spiculation (87.84%, 65/74), intralesional calcification (62.16%, 46/74).With the pathology of routine preoperative ul-trasound diagnosis coincidence rate was 91.38%(106/116).②Ultrasonic elastography in diagnosis of breast benign lesions in 39 ca-ses, 66 cases of malignant lesions, benign lesions of ultrasound elastography score of 1-2 (92.86%, 39/42); malignant lesions of ultrasound elastography score of 3-5 (89.19%, 66/74);and the pathology of preoperative ultrasound elastography diagnosis coinci-dence rate was 90.51% (105/116).③Preoperative ultrasound elastography and conventional ultrasound diagnosis of 42 cases of be-nign lesions, 68 cases of malignant lesions, and pathological diagnosis coincidence rate was 94.82% (110/116).Conclusion Ul-trasound elastography and conventional ultrasound examination can improve the resection of benign and malignant breast lesions diag-nosis in primary hospital diagnosis, as an effective method for the detection of breast cancer before operation .

0.05;AGC R 1 to R 2 P 0.05.The invasive depth of the lesion corresponded to the degree of lymph node metastases.No relation was found between tumor size and the survival rate.The prognosis of type Ⅲ EGC and AGC with infiltration was poor.Conclusions: Biological behavior of gastric cancer can be used as a guide to operation type.We proposed that EGC should undergo subtotal gastrectomy plus R 1 or selective R 2 ,and AGC should undergo subtotal gastrectomy or near total gastrectomy plus R 2 or selective R 3 ,with a margin of at least 5 cm from the tumor.

BACKGROUND:Alpha-calcium sulfate hemiydrate/biphasic bioceramics (α-CSH/BCP) as a bone repair material has been widely used in the clinic, but there are stil some deficiencies. OBJECTIVE:To observe the effect of α-CSH/BCP on the repair of bone defects of the radius in rabbits. METHODS:The unilateral radius of 18 adult New Zealand white rabbits was selected to establish bone defect models, and then these rabbit models were randomized into three groups that were treated with α-CSH,α-CSH/BCP, BCP materials, respectively. At 4, 8, 12 weeks after implantation, bone samples were taken for gross and X-ray observations. RESULTS AND CONCLUSION: (1) Gross observation: At 12 weeks of implantation, the bone defect was completely repaired in the α-CSH/BCP group, and the defected radius recovered basicaly; in the α-CSH group, bone defects were visible; and in the BCP group, there was stil some material for filing and coverage. (2) X-ray observation: In the α-CSH group, the degradation of implanted materials was faster than new bone formation, and bone defects were visible; in the α-CSH/BCP group, bone defects were healed, cortical bone remodeling was good, and the bone marrow cavity was re-canalized; in the BCP group, the implanted materials were stil visible, and bone defects were not repaired. These findings indicate that the α-CSH/BCP bone repair material can significantly promote the repair of bone defects of rabbit radius, with a better repair effect than α-CSH or BCP alone.

OBJECTIVE:To systematically review the efficacy and safety of escitalopram versus paroxetine in treatment of se-nile patients with depression in China,and provide evidence-based reference for clinical treatment. METHODS:Retrieved from CJFD,VIP,Wanfang database,CBM database,randomized controlled trials(RCT)of escitalopram(test group)versus paroxetine (control group) in the treatment of senile patients with depression in China were collected. After quality evaluation and data ex-tract,Meta-analysis was performed by using Rev Man 4.2 statistics software. RESULTS:A total of 14 RCT were included,involv-ing 1 148 patients. Results of Meta-analysis showed there was no significant difference in the cure rate[OR=1.20,95%CI(0.93, 1.53),P=0.16],significant effective rate[OR=1.23,95%CI(0.94,1.61),P=0.12],the incidences of headache[OR=0.81,95%CI (0.40,1.65),P>0.05],the incidences of tachycardia [OR=0.37,95%CI(0.09,1.52),P>0.05],the incidences of insomnia [OR=1.26,95%CI(0.33,4.82),P>0.05] and the incidences of tremor [OR=0.31,95%CI(0.04,2.24),P>0.05] between test group and control group;the incidences of xerostomia[OR=0.50,95%CI(0.31,0.80),P<0.05],the incidences of nausea[OR=0.49,95%CI (0.36,0.66),P<0.05],the incidences of sweating [OR=0.31,95%CI(0.15,0.62),P<0.05],the incidences of constipation[OR=0.31,95%CI(0.15,0.64),P<0.05],the incidences of dizziness[OR=0.38,95%CI(0.20,0.72),P<0.05] and the incidences of an-orexia[OR=0.45,95%CI(0.21,0.99),P<0.05] in test group were significantly lower than control group,there were significant dif-ferences in 2 groups. CONCLUSIONS:The efficacy of escitalopram and paroxetine is similar in the treatment of senile patients with depression,however,the safety of escitalopram is better than paroxetine. Due to the limit of methodological quality and sam-ple size,it remains to be further verified with more rigorously designed and long-term follow-up of large-scale RCT.

A PCR method was used to amplify the sequence encoding the mature peptide of?-mannanase of Bacillus subtilis. The gene was inserted into the Pichia pastoris vector pPIC9K, downstream of?-factor signal peptide sequence. The resultant recombinant plasmid pPIC9K-MAN was lineared by BglII digestion and introduced into the host Pichia pastoris GS115 by PEG method. After screen, the recombinant P. pastoris strain MAN22 was obtained and fermented in large scale 5L fermenter. The recombinant mannanase activity could reach to 1102IU/ml. The properties of the recombinant mannanase were characterized.

Trehalose is a naturally occurring non-reducing disaccharide. This sugar has been known as a protector of biomembrane and macromolecules. And it has been widely used in foods, medicines, cosmetics. Trehalose synthase (TreS) is an intramolecular transglycosylase. It can catalyze the conversion of maltose into trehalose in one step. As the simple protocol and cheap substrate, it is very prospect in the industrial production. Here we have discussed the properties, catalytic mechanism and gene-engineering of TreS, and also proposed some solutions to its present research problems.

Objective: To analyze the expression of mecp2 gene at mRNA and protein;Cerebral cortex level in the cerebral cortex of the normal Wistar rat throughout development. Methods: We chose the 15th day (E15), 17th day (E17), 19th day (E19) of embryo period, the day of birth (P0), the 7th day (P7), the 14th day (P14), the 28th day (P28) of postnatal period, and adulthood as analyzing time points. The expression of mecp2 gene at mRNA level was analyzed by real time PCR and Northern blot. The expression of MeCP2 protein was analyzed by Western blot. Results: There was one type of mecp2 mRNA transcript (approximately 10 kb) expressed in the cerebral cortex of the normal Wistar rat. The expression level of mecp2 mRNA varied subtly during the development. There was one type of MeCP2 protein (75 000) expressed in the cerebral cortex of the normal Wistar rat. The expression level of MeCP2 protein remained the lowest on E15, from E19 to adulthood the expression levels of MeCP2 protein increased dramatically compared with that on E15. From P7 to adulthood, the differences of expression between two time points were subtle. Conclusion: The expression level of MeCP2 protein increases as the neurons in the cerebral cortex of normal Wistar rat grow mature. This indicates that MeCP2 protein is very important to neuron's maturation, and probably has relationship with maintaining maturation state of neurons.
