Objective Non-alcoholic fatty liver ( NAFL) is a metabolic disease and levocarnitine can be used to improve the energy metabolism of the patient .This study aimed to evaluate the clinical efficacy of levocarnitine in the treatment of NAFL . Methods We retrospectively analyzed 85 cases of NAFL treated by lifestyle intervention (control group, n=40) or by lifestyle intervention +levo-carnitine medication (medication group, n=45).In addition to lifestyle intervention, the patients in the medication group received oral levocarnitine at 10 mL tid for 4 weeks followed by a reduced dose of 10 mL bid for another 8 weeks. Results Twelve weeks after treat-ment, 37 cases (82.2%) in the medication group showed remarkable improvement and the other 8 failed to respond.In the control group, 23 cases (57.5%) were improved and 17 cases remained unimproved .There were statistically significant differences in the rate of therapeutic effectiveness between the two groups of patients (P<0.01).No adverse effects were observed during the levocarnitine medi-cation. Conclusion Lifestyle intervention +levocarnitine medication can improve NAFL .

Objective: To study the axonal effect and the expression of integrin α6β4 during Schwann cell(SC) differentiation and myelination. Methods: Schwann cells were dissociated from the sciatic nerve of neonatal Waster rats and neurons dissociated from spinal cord. Singal cultures and purified populations of SC were cocultured with NC. Four methods (contrast microscope, scanning electron microscopy(SEM), immunocytochemistry method and in situ hybridization ) were used. Results: The separately cultured Schwann cells showed MBP negetive by immunocytochemistry method. But cocultured SC were shown positive. SEM showed that Schwann cells' membrane loop progressively circumnavigated around the axon during myelination, which suggested that the non-myelinating SC(nMSC) transformed to myelinating SC (MSC). In situ hybridization showed integrin α6β4 positive signals only on the outer surface of the Schwann cell-axon unit in SC coculture with NC. Conclusion: The differentiation and maturation of SC depend on axon, and the activity of integrins is expressed by axon. Axonal contact induces the expression of α6β4 during SC myelination, which suggests that integrin α6β4 is an important mediator of interactions of myelinating SC with the basal limina.

Objective To evaluate the effect of medicial and surgical treatment for juvenile hyperthyroidism.Methods Ortapazole was administ rated separately in drug therapy group for 1.5-2 years.Bilateral subtotal thyroidectomy was done in surgical therapy group.Results In drug therapy group,effective rate was 60 percent in 6 months and 70 percent in one year.Recurrence rate was 40 percent after drug withdrawal in 2 years curative rate was 60 percent.In surgical therapy group,the average stay in hospital was 16 days.There was no nerve injury,parathyroidal hypofunction,thyroid crisis or hypothyroidism complications,with 100 percent curative rate after 2 years′ followup.Postoperative growth and development were normal.Conclusions Surgical treatment may be suitable for those who have no response to drug therapy,with recurrence after drug withdrawal,whose compression symptom was obvious,with moderate and severe hyperthyroidism or those who could not take medicine persistently.Bilateral subtotal thyroidectomy applied in juvenile hyperthyroidism could achieve quick and better recovery,and has no influence on the juvenile growth and development.

Allergic reactions caused by traditional Chinese medicine injections (TCMIs) become a greatest concern in the clinic application safety. The integral animal evaluation method commonly used in the preclinical evaluation for allergic reactions of TCMIs was not sensitive, specific, quick and objective in observation indexes. Therefore, more researchers have paid attention to the in vitro test method for evaluating allergic reactions induced by TCMIs. Currently, the methods for evaluating allergic reactions induced by TCMIs are mainly targeted at type I allergic reaction and anaphylactic reaction, with only a few in vitro methods for evaluating type II allergic reaction. In this paper, researchers summarized relevant literatures published about evaluation methods for allergic reactions induced by TCMIs in recent years.

Objective The control rate of blood pressure in hypertension patients is very low in our country , while follow-up intervention can significantly improve the situation .This study aimed to evaluate the clinical effects of anti-hypertension under follow-up intervention . Methods From October 2013 to October 2014 , 125 patients with hypertension were chose as the study objectives after first clinical anti-hypertension and were divided into intervention group (follow-up,n=65) and control group(no follow-up,n=60). Comparative analysis was made in blood pressure control , compliance with therapy and cardiovascular event incidence between the two groups after 12 weeks'intervention. Results After 12 weeks, diastolic and systolic blood pressure in intervention group was signifi-cantly lower than that in control group (P<0.05).Significant difference was also found in the compliance with drug-taking between in-tervention group and control group (73.8%vs 43.3%, P<0.01).During the follow-up period, 1 case in the control group suffered stroke and unstable angina pectoris hospitalized for treatment . Conclusion Follow-up intervention after clinical service can improve the efficacy of blood pressure control and encourage the patients to live healthy lifestyle .

Objective To explore virtual three-dimensional (3D)model for intravascular interventional devices,the method of preoperative simulation and its value in clinical work.MethodsThe virtual models including catheter,guide wire,stent and coil were established by using the 3D moulding software of 3D Studio MAX R3. The interventional preoperative simulation was performed on personal computer including 21 patients of cerebral aneurysm embolization ( anterior communicating artery 5,posterior communicating artery 10,middle cerebral artery 3,internal carotid artery 2,and vertebral artery 1 ),during interventional procedures,the surgeon relied on the simulation results for plastic micro-guide wire,catheter and the release of micro-coils and stents.Results( 1 ) All the virtual instruments and real instruments had similar shape,the overall tine for constructing virtual model was about 20 hours.The preoperative simulation took 50 to 80 minutes. (2) The simulation result of catheter insertion in the 18 cases had relevant value to guide micro-catheter,molding micro-guide wire tip,and shortened the operating time.For embolization,the simulation results of filling coil and releasing stent were similar to surgical results in 76％ of the patients (16/21).(3)For teaching and training,93％ (38/41) of doctors in training believed that preoperative simulation facilitated the understanding of surgery. ConclusionsThe method of virtual model of intravascular interventional devices was reliable.The preoperative simulation results could be used to guide practical clinical operation with relatively high degree of similarity,and could play a role in promoting researches on interventional virtual operations.

Objective To investigate kupffer cells (KCs) expressing indoleamine 2,3-dioxygenase(IDO)in the inhibition of allogeneic T-cell proliferation in vitro. Methods Real-time PCR was used to investigate the expression of IDO mRNA and FasL mRNA in KCs pretreated with or without IFNγ. High performance liquid chromatography was used to analyze the catabolism of tryptophan by IDO from KCs. Allogeneic T-cell response was used to confirm the inhibition of KCs in vitro. The proliferation of lymphocytes was detected using [3 H] thymidine incorporation. Cell cycle and lymphocyte apoptosis were evaluated by flow cytometric assay. Results Real-time PCR revealed IDO mRNA and FasL mRNA expression in KCs pretreated with IFN-γ. IDO catabolic effect was confirmed by a decrease in tryptophan and increase in kynurenine concentration. KCs expressing IDO and FasL from BABL/c mice acquire the ability to suppress the proliferation of T-cells from C57BL/6, which could be blocked by the addition of 1-methyl-tryptophan and anti-FasL antibody. The co-cultured T-cells with KCs expressing IDO and FasL could induce allogeneic T-cell apoptosis and exhibited cell-cycle arrest in G1. Conclusion In addition to the Fas/FasL pathway, IDO may also play an important role in KCs to inhibit allogeneic T-cell proliferation in vitro.
