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 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 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 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.

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.

Objective To evaluate the preoperative diagnosis and treatment of primary non-specific ureteritis,and to better understand this disease.Methods Three cases of primary non-specific ureteritis (1 man and 2 women)were reported.Their age was 28,38,68 years,respectively.One ease was found to have hydronephrosis on B-ultrasound at physical examination with no symptoms,and 2 had abdominal pain. The lesions were detected in lower part of the ureter in 2 cases,and in middle in I.The patients were diag- nosed preoperatively with combined use of MRU and ureteroscopy.Partial resection of the diseased part of the ureter was performed in all the cases.Results Pathological findings confirmed the diagnosis of non-spe- cific ureteritis.Microscopy showed necrotic tissue and inflammatory cell infiltration of ureteral mucosa,dilated and congested blood vessels,hypertrophic muscular layer,and proliferation of fibrous tissue.During the fol- low-up of 2 years,the patients had no symptoms and were free from hydronephrosis.Conclusions The eti- ology of primary non-specific ureteritis is unclear,and no typical symptoms can be found clinically.Combined use of MRU and ureteroscopy is helpful for definite diagnosis of the disease.Partial resection of the diseased part of the ureter has good results.

Objective To explore the features of transsphenoidal microsurgical treatment of male pro- lactinoma and to evaluate the sexual function before and after transsphenoidal microsurgery.Methods A se- ries of 23 cases male prolactinoma were analysed combined with retrospective and prospective study.9 casese with sexual disfunction had finished the International Index of Erectile Function with 15-item questionnnaire (ⅡEF-15) before and after the surgery.Results 8/10 cases treated with dopaminergic agonist combined with surgery achieved complete remission,while only 4/13 cases achieved complete remission with surgery on- ly(x~2=5.490,P=0.036).Aecoding toⅡEF-15,sexual function improved after surgery in 9 cases(paired- sample) t test,P＜0.05).Conclusion Transsphenoidal microsurgical treatment of prolactinoma may im- prove the male sexual functions.Dopaminergic agonist combined transsphenoidal microsurgery may achieve a better outcome.
