The transplants of one-year-old Glycyrrhiza uralensis Fisch. were subjected to five concentrations of MnSO4-H2O (0, 1.81, 18.1, 36.2 and 54.3 mg·L(-1)) culturing in vermiculite. qRT-PCR and HPLC were respectively used to measure the relative expression of SQS1 gene and the content of glycyrrhizic acid of G. uralensis in different concentrations of MnSO4·H2O. This is to explore discuss the effects of the expression of SQS1 gene and the accumulation of glycyrrhizic acid by Mn treatment. The results showed both the expression of SQS1 gene and the content of glycyrrhzic acid of G. uralensis tended to rise after the fall of the first with the increase of concentration of Mn treatment. And they were of very significant positive correlation (P<0.01, r=0.737). Relative expression of SQS1 gene reached the highest 7.90 under 18.1 mg·L(-1) MnSO4·H2O treatment. It was very significantly different between 18.1 mg·L(-1) concentration of MnSO4·H2O treatment and CK (0 mg·L(-1)), 1.81, 36.2 and 54.3 mg·L(-1) (P<0.01), and 1.75, 1.37, 1.37, 2.33 times respectively. The content of glycyrrhizic acid reached the highest under 1.81 and 18.1 mg·L(-1) MnSO4·H2O treatment, and there were not significant difference (P>0.05). It was very significantly different between them and other concentrations of MnSO4·H2O treatment (P<0.01). This study suggests the appropriate concentration of Mn treatment could certain promote the expression of SQS1 gene and the accumulation of glycyrrhizic acid of G. uralensis.

Objective To observe the clinical efficacy of acupuncture in treating hemifacial spasm and its effect on the surface electromyogram signal of orbicularis oculi muscle under contraction state.Method Seventy-six patients with hemifacial spasm were randomized into a treatment group and a control group, 38 cases in each group. The control group was intervened by conventional medications, while the treatment group was by acupuncture in addition to the intervention given to the control group. The surface electromyogram signal of orbicularis oculi muscle under contraction before and after intervention, clinical efficacies, and side effects were compared between the two groups.Result The MF and MPF values were significantly changed after intervention in both groups (P<0.05). After intervention, the MPF value in the treatment group was significantly different from that in the control group (P<0.05). The total effective rate was 92.1% in the treatment group versus 63.2% in the control group, and the difference was statistically significant (P<0.05). The TESS scores after intervention were significantly different from that before intervention in both groups (P<0.05). After intervention, the TESS score in the treatment group was significantly different from that in the control group (P<0.05).Conclusion Acupuncture is an effective method in treating hemifacial spasm, and it can release muscle fatigue.

Objective To observe the effect of immunity condition and clinical manifestations of children with recurrent oral-ulcer(ROU)treated with aciclovir(ACV) and a-polyresistin.Methods Forty-eight patients with ROU were randomly divided into whole treated group(25 cases)and partial treatment group(23 cases).The changes of their peripheral blood lymphocyte subgroups,before and after treatment,were measured and contrasted to analyze the relationship with curative effect.Results The ratios of CD3,CD4,and CD4/CD8,after the treatment,increased obviously,while CD8 lowered obviously in treatment group(P0.05).The total clinical efficacy rate was 47.82%,moreover the patients were recurrent after 1 year.Conclusions ACV and a-polyresistin,through antivirus and regulating the immunity function get the 96% total clinical efficacy rate,and that controle the recurrent rate.It is superior to the traditional method.

Objective To develop a set of high-frequency ultrasound grayscale blood flow imaging system based on field programmable gate array (FPGA) to execute simultaneous imaging of superficial blood flow and tissues.Methods This system was mainly composed of an ultrasonic transducer,an ultrasonic transmission and receiving modules,imaging software in host computer and peripheral equipment.A PVDF transducer with the frequency between 20 and 50 MHz was used for the ultrasonic transducer.In transmission and receiving modules,the radio frequency echo signals were digitized by high-speed A/D.Then the digital signals were transmitted,added,filtered,demodulated,log amplified,double sampled,and lastly transferred to the host computer by USB interface for real-time display.Results A vascular 1 mm far form the surface of the hand skin was examined by this system.Four blood flow images were obtained in corresponding with four transmission frequencies.Conclusion Real-time superficial organ blood flow imaging is realized by this system.The solution has the architecture concise and clear,and lays an experimental foundationfor high-frequency ultrasound gray-scale blood flow imaging.

Objective To investigate the diagnostic value of procalcitonin(PCT)as an early indicator for sepsis.Methods Serum levels of PCT and C-creative protein(CRP)and white blood cell (WBC)count were measured in 30 patients in critical condition hospitalized at an intensive care unit(ICU) with diagnosis of systemic inflammatory response syndrome(SIRS).They were divided into two groups, sepsis and non-sepsis,based on their clinical manifestations and results of lab tests.Blood specimen was collected from each patient for measurement of PCT,CRP and WBC count on the 1~(st),3~(rd)and 7~(th)day after hospitalization and bacteriological culture for blood and sputum,and chest X-ray was performed,as well. Acute physiology,age and chronic health evaluation(APACHE Ⅱ)was made on the 1~(st),3~(rd)and 7~(th)day after hospitalization to assess their ill condition.Their prognosis were judged on the 28~(th)day of the follow-up. Results Serum level of PCT increased significantly in the sepsis group(with the highest of 10.13 ng/ml), as compared with that in the non-sepsis group.Sensitivity,specificity and predictive value of a positive test for a cut-off value of serum level of PCT at 0.5 ng/ml were 97.0%,91.7% and 82.1%,respectively, which were all better than those of serum level of CRP and WBC count.Serum level of PCT in the patients was significantly associated with their prognosis,and PCT in those died was significantly higher than that in those survived.Whereas,serum level of CRP and WBC count elevated in both groups,but the difference between the two groups did not reach a level of statistical significance.Conclusion Serum level of PCT can be used as an early indicator for judgment of sepsis for a patient with infection and reflection of severity of illness.

GlyoxalaseⅠthat presents in all human tissues detoxifies α-oxoaldehydes and prevents the formation of advanced glycation end products(AGEs).AGEs and their main precursor namely methylglyoxal(MG)produce cytotoxicity and have extensive relationship with diabetic complications.Therefore,to elevate glyoxalaseⅠactivity may be a new path to release such complications.

Objective To evaluate the efficacy and safety of the endovascular interventional minimally invasive techniques(IMIT)for treatment of carotid artery iniury. Methods A total of 111 cases of carotid artery injury diagnosed by digital subtraction angiography(DSA)were treated with IMIT.Except for 1 case of extracranial segment injury of internal carotid artery treated with transcatheter stentgraft placement to obturate the rupture of carotid artery,the other 110 cases of intracranial segment injury of internal carotid artery(ICA)were treated with embolization with balloons in 73,embolization with coils in 12,injection of NBCA and PVA in 6,stent-graft placement in 11 and embolization with multiple materials in 8. Results Angiography demonstrated rupture of extracranial segment of internal carotid artery and arteriovenous fistula(AVF)at the neck in 1 case,traumatic carotid cavernous fistula(TCCF)in 83.traumatic pseudoaneurysm at intracranial segment of carotid artery in 14 and both TCCF and pseudoaneurysm in 13.The interventional treatment succeeded in all cases and interual carotid arteries were well protected in 62 cases.Completion angiography documented complete obliteration of the fistulas,with complete disappearance of the clinical symptoms in 110 cases and improvement in 1.Minor complications occurred in 2 cases,without death occurred.During the follow-up for 1-14 months,16 cases reexamined with DSA,which showed that the symptoms of 3 cases reoccurred,2 of whom were cured by re-embolization and 1 was under clinical observation. Conclusions IMIT including transcatheter selective embolization and stent-graft implantation is minimally invasive,safe and effective for treatment of carotid artery injury.

OBJECTIVETo compare the effectiveness of percutaneous microwave ablation ( MWA) versus hepatectomy for multifocal hepatocellular carcinoma.

METHODSFrom August 2002 to March 2012, one hundred and twenty-two patients with multifocal hepatocellular carcinoma (diameters 1 to 7 cm, 2 to 4 lesions) were treated by either complete MWA or radical hepatectomy, and their clinical data were collected and analyzed.The patients were divided into MWA group (n = 50) and resection group (n = 72), and the resection group was matched by MWA group based on clinical parameters. The survival and complications in the two groups were compared.

RESULTSThe overall 1-, 3- and 5-year survival rates were 100.0%, 73.0% and 62.0%, respectively, in the MWA group, and 80.0%, 56.0%, and 41.0%, respectively, in the resection group (P < 0.05). The corresponding recurrence-free survival rates were 88.0%, 63.0%, and 52.0% in the MWA group, and 68.0%, 45.0%, and 36.0%, respectively, in the resection group (P< 0.05). The multivariate Cox regression analysis indicated that albumin level, performance status, treatment modality, and tumor size were independent prognostic factors.

CONCLUSIONCompared with hepatectomy, percutaneous microwave ablation is a minimally invasive and reproducible procedure, and can improve the survival in patients with multifocal hepatocellular carcinoma.
