The total RNA was extracted from ginseng leaves of Panax ginseng. The Cu/Zn-SOD gene was amplified via RT-PCR and the pET-28(a)-Cu/Zn-SOD expression vector was constructed. The pET-28 (a)-Cu/Zn-SOD recombinant plasmid was transformed into Escherichia coli BL21 (DE3) competent cells and was induced by IPTG in order to select optimal induction of expression conditions. The target protein was purified by the nickel ions (Ni ) affinity chromatography and the target protein enzyme activity was determinated by the xanthine oxidase method. The similarity of the Cu/Zn-SOD gene sequences and the Cu/Zn-SOD gene sequences of Korean ginseng in NCBI was 99. 00%. The target protein expression level was about 44.42%, and the molecular weight was 16.30 kDa after the pET-28(a)-Cu/Zn-SOD recombinants were induced by IPTG. The purified Cu/Zn-SOD protease activity reached 10,596.69 U x mg(-1). The P. ginseng pET-28(a)-Cu/Zn-SOD prokaryotic expression vector was built by the method of molecular biology, which provided the foundation for studying the Cu/Zn-SOD biology function.

OBJECTIVETo compare with the clinical applications of routine-subtraction and dual-energy subtraction cervical arteries computed tomographic angiography (CTA) for cervical arteries imaging.

METHODSScanning was performed in 45 patients with clinically suspected cervical arteries disease with dual-source CT. The data of two different energy were collected only at one scanning. The data post processing include: conventional bone-removal digital subtraction (routine-subtraction) was performed with plain and 80 kV enhanced scanning. Volume render (VR) and maximum intensity projection (MIp) reconstruction were finished. Direct bone-removal digital subtraction (dual-energy subtraction) was performed with 80 and 140kV enhanced scanning that have different energy, and saving the data of subtraction. VR and MIp reconstruction were finished. The image quality, which was divided into four grades, was compared between these two groups. The effective radiation dose was also compared.

RESULTSFor normal vessels, no abnormality was found in 24 of 45 cases, with the common carotid artery and its branches clearly displayed with both two methods. The image quality was not significantly different between dual-energy subtraction CTA and routine subtraction CTA (P>0.05) . For stenotic vessels, 45 stenotic vessels in 21 cases were clearly displayed clearly with both two methods (P>0.05) . The effective radiation dose was decreased by 17.3 % for dual-energy subtraction CTA when compared with routine-subtraction CTA (P<0.01) .

CONCLUSIONSBoth routine-subtraction and dual-energy subtraction CTA can clearly display normal and stenotic vessels. The radiation exposure dose is relatively lower in dual-energy CTA. The dual-energy subtraction CTA has better effectiveness when used for non-cooperation patients.

Carvedilol group included 20 cases,bisoprolol group included 20 cases,and the course was 24 weeks.Blood pressure and heart rate were measured and symptoms and signs were recorded.At the end of placebo and in 24 weeks heart ultrasound,blood routine,serum glucose,blood lipid,hepatic function and renal function were examined.SBP,DBP and heart rate of patients in two groups decreased obviously.There were significant differences between the two groups.Ventricular hypertrophy of carvedilol group improved than that in pretherapy.There were significant differ- ences between the two groups.Conclusion Carvedilol was well-tolerated with less side effects such as mild headache,tiredness,dizziness,slightly elevating of serum glucose.Carvedilol could well treat the mild moderate essen- tial hypertension effectively and safely by 12.5～25mg once daily.

·AIM: To observe the therapeutic effect of visual perception training combined with total nutrition meal sequential therapy in the treatment of myopic amblyopia.·METHODS:Totally 73 children ( 135 eyes ) with myopic amblyopia were divided into control group ( 36 cases, 67 eyes) and treatment group (37 cases, 68 eyes) according to random number table. The control group were treated with traditional spectaculars and grating covering combined with fine eyesight training;the treatment group were treated with visual perception training combined with total nutrient meal sequential therapy. The visual acuity, diopter and average diopter of two groups were compared before and after treatment at 3, 6mo and 1a. The curative effect of two groups of children was compared after 1a treatment. And the adverse reactions were recorded in two groups during the treatment period. The recurrence rate of amblyopia in 1a follow-up was compared between two groups.·RESULTS: The difference of visual acuity between two groups was not significant at 3mo (P>0. 05). The visual acuity of the treatment group was significantly higher than that of the control group at 6mo and 1a (P<0. 05). There was no significant difference in diopter between the two groups after 3, 6mo and 1a (P>0. 05), but the average annual refractive changes in the treatment group were significantly lower than that in the control group ( P<0. 05). The basic cure rate and total effective rate of the treatment group were significantly higher than that of the control group (P<0. 05). There were no severe adverse reactions occurred between two groups during the treatment period. The recurrence rate of amblyopia in the treatment group was significantly lower than that in the control group (P<0. 05) after 1a follow-up.· CONCLUSION: Visual perception training combined with total nutrition meal sequential therapy in the treatment of myopic amblyopia in preschool children can significantly improve patients' visual acuity, reduce the average annual diopter changes, improve the therapeutic effect, reduce the recurrence rate of amblyopia.

Hypertension is a common complication after renal transplantation. Among post-transplantation patients died of cardiovascular diseases, about 41% have hypertension. Hypertension is an independent risk factor for kidney transplant failure. Post-transplantation hypertension can be caused by many factors, including the use of immunosuppressants. When the blood pressure exceeds 130/90 mmHg in a kidney transplant recipient, it is reasonable to provide active medical intervention. In summary, prevention and treatment of hypertension is important to prolong the survival of kidney transplant recipients.
