The fusion of cranio-jaw-facial CT and MRI image was obtained. It suggested that the fusion of cranio-jaw-facial CT and MRI image was feasible in clinical practice. It can provide the image basis helping the analysis of diagnosis and treatment for diseases of the cranio-jaw-facial region with complicated anatomical formation.

OBJECTIVETo explore the clinical effects of lattice ultra pulse carbon dioxide laser combined with traditional Chinese medicine ( Fuchunsan ) on the treatment of postburn hyperplastic scar.

METHODSSixty-three patients with hyperplastic scar after burn injury hospitalized from February 2012 to June 2014 in our department were treated with lattice ultra pulse carbon dioxide laser combined with traditional Chinese medicine (Fuchunsan). Patients were divided into early stage group (E, n = 35), middle stage group (M, n = 25), and late stage group ( L, n = 3) according to the formation time of scar, which was respectively 3 weeks to 3 months, longer than 3 months and less than or equal to 6 months, and 3 to 15 years in groups E, M, and L. The number of times of laser treatment of patients in each group was recorded. The degree of scar pain in patients of the three groups was assessed by the Numerical Rating Scale (NRS) before treatment and after treatment for 1, 2, and 3 times. The scar condition of patients in groups E and M was assessed by the Vancouver Scar Scale (VSS) before treatment and after treatment for 1, 3, and 5 times. Patients in group L did not receive VSS assessment but were evaluated by clinical observation only. Photos of scar in treating area were taken before treatment and after treatment for 3 and 5 times to evaluate the clinical effect. Data were processed with t test.

RESULTSPatients in groups E and M were treated with laser for (4.8 ± 1.1) and (7.7 ± 2.1) times respectively. In group L, the treatment was stopped in 2 patients after laser treatment for 5 times, and 1 patient received laser treatment for 12 times. The degree of pain in patients of groups E and M was alleviated significantly after treatment for one time, and the number of patients scoring 1-4 point(s) in NRS increased from 5 cases to 38 cases. After treatment for 2 and 3 times, the increase in the number of patients scoring 1-4 point (s) in NRS was on a small scale. Before treatment and after treatment for 1 time, VSS scores of patients in groups E and M were similar (with values respectively 0.641 and 0. 082, P values above 0. 05). After treatment for 3 and 5 times, VSS scores of patients in group E were respectively (9.2 ± 0.8) and (7.0 ± 1.1) points, which were significantly lower than those in group M [ (9.7 ± 1.0) and (8.2 ± 1.0) points, with values respectively -1.993 and -4.433 , P < 0.05 or P < 0.01]. After treatment for 3 times, the rate of improvement in appearance was respectively 88.6% (31/35) and 72.0% (18/25) in groups E and M, and it was respectively 100.0% (35/35) and 96.0% (24/25) after treatment for 5 times. No significant effect in appearance was found in the 3 patients in group L.

CONCLUSIONSEarly application of lattice ultra pulse carbon dioxide laser combined with traditional Chinese medicine (Fuchunsan) for the treatment of postburn hyperplastic scar is effective.

Objective In order to understand whether recombinant human growth hormone(r-hGH) can improve the idiopathic short stature(ISS) boys' final adult height(FAH).Methods We measured 16 cases diagnosed as ISS boys FAH, divided into 2 groups, of which 9 cases were not given r-hGH treatment, treatment group ,7 patients received r-hGH treatment, a dose of 0.1 ～ 0.13 U· kg-1·d-1, before going to sleep subcutaneous injection, duration of treatment was 6 ～ 20 months ( 11.9 ± 5.2 months).Results The treatment group compared with the average FAH FAH observation group had significantly improved the average(t =2.219,P<0.05).Conclusion r-hGH can improve the ISS boys FAH, but early treatment, the longer the course the more obvious effects.

Background The protective effects against reperfusion injury of cardioprotective drugs have recently been evaluated and found to be inadequate. Guanxinshutong (GXST), a combination of the traditional herb and Mongolian medicine, is effective and safe in treating angina pectoris in clinical trials. We assess the cardioprotective effects of GXST against myocardial ischemia and reperfusion (MI/R) injury in rats and explore its possible mechanism. Methods Forty-five male Sprague Dawley rats were randomized into three groups: non-MI/R group (Sham, n = 15), MI/R group treated with vehicle (Control, n = 15) and MI/R group treated with GXST (Drug, n = 15). MI/R was induced by ligation of the left anterior descending coronary artery (LAD) for 30 minutes, followed by 2/24 hour reperfusion in the Control and Drug groups. In the Sham group, the LAD was exposed without occlusion. GXST powder (in the Drug group) or saline (in the Control and Sham groups) were administered via direct gastric gavage from 7 day prior to surgery. Blood samples were collected from the carotid artery (10 rats each group) after 2 hours of reperfusion, to determine the levels of tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), interleukin-6 (IL-6) and intercellular adhesion molecule-1 (ICAM-1) using enzyme-linked immunosorbent assays. The animals were then sacrificed and the hearts were harvested for histopathology and western blot analysis. Infarct size was measured in the remaining five rats in each group after 24 hours reperfusion. Results GXST significantly decreased levels of TNF-α, IL-1β, IL-6, ICAM-1, apoptosis index (AI) and infarct size. GXST also obviously inhibited nuclear factor kappa B (NF-κB) activity when compared with the Control group (all P < 0.05). Conclusions GXST is effective in protecting the myocardium against MI/R injury in rats. Its possible cardioprotective mechanism involves inhibition of the inflammatory response and apoptosis following MI/R injury.

Aim To explore the pharmacological mechanism and the effects of polysaccharide sulfat(PSS) on cardiovascular diseases induced by type 2 diabetes mellitus(DM) through observing the risk factors.Methods Type 2 diabetic animal model was established by high-sugar and high-fat diets,combined with injection of small amount streptozotocin(STZ 20 mg?kg-1,iv).Adult male wistar rats were divided into five groups: normal control group,model group,polysaccharide sulfate group,metformin group and lovastatin group.They were treated with exact medicne for 8 weeks,but control group and model group were treated with 0.9% Nacl.During this process,FBG and serum lipid concentrations were measured.22 weeks later,the rats were sacrificed.The activity of tissue-type plasminogen activator(t-PA) and plasminogen activator inhibitor type-1(PAI-1) were detected by chemical methods.The aortas were collected for histopathlogical,immunohistochemical and Western blot studies.Results FBG concentrations and serum lipid(TC,TG,LDL) levels decreased in PSS group as compared from those of model group(P

Objective To evaluate the efficacy of double filtration plasmapheresis (DFPP) in the treatment of patients with refractory rheumatoid arthritis (RA). Methods Eighty-two patients were randomly aesigned,42 to the DFPP group and 40 to the no-DFPP group. All patients previously experienced an incomplete response to 2-3 dis-ease-modifying antirheumatic drugs (DMARDs) and 1-2 nonsteroidal anti-inflammatory drugs (NSAIDs) or predni-sene. All patients received sulphasalazine (SASP,0.75 g three times daily) plus methotrexate (MTX, 10 mg orally once weekly). DFPP was performed once a week for 2-3 sessions. A total of 121 plasmapheresis procedures were per-formed in 42 patients. Control patients did not receive sham DFPP. The efficacy measures recorded one day after the final treatment and latest month in follow up for 12～24 months included the American College of Rheumatology 20% ,50% ,and 70% improvement criteria (ACR20, ACR50, and ACR70), the Health Assessment Questionnaire estimate of disability (HAQ); and the disease activity index. Results Patients in the DFPP group had ACR 20, ACR 50 and ACR 70 improvements of 100% ,92.9% and 81.0%,as compared with the patients in no-DFPP group 17.5% ,0,and 0 (P<0.001). Significant change from baseline was observed in HAQ scores in the DFPP group but not in the no-DFPP group (P<0.001). The changes from baseline in the disease activity scores were significantlygreater than in the no-DFPP group (P<0.001). Conclusion DFPP therapy significantly alters the signs and symp-toms of refractory RA. There are significant increases in physical function and improvement in quality of life.

Objective To summary and discuss the curative effect and experience of repairing serious and complicated soft tissue defects of traumatic shank by flap or musculocutaneous flap by anatomosis.MethodsFrom October 2009 to December 2011, the wounds of 59 patients suffering from serious and complicated soft tissue defects of traumatic shank were covered by VSD after repeated debridement,when the conditions of the whole bodies were stable and the local acute infection was controlled in the main. Fifty-six patients were repaired by a single flap or musculocutaneous flap attributing to the fresh granulation, three patients were repaired by compound tissue flaps because a single flap was insufficient. Five patients who had no available blood vessels at recipient site were repaired by flaps with bridge cross vascular anatomosis. The compound flaps were no more than 2 pieces, the maximum area of flap was 32 cm × 13 cm, the minimum was 15 cm × 8 cm.Results The flaps of all of 59 cases survived, fifty-seven cases were healed in one stage, two in two stage, one case had complication of infection at donate site due to the hematocele, and was cured by debridement and skin graft. Serious and complicated soft tissue defects of shanks were repaired by reconstruction,damaged limbs were salvaged,the functions of the legs were reserved. Conclusion It is the most effective and irreplaceable way that using flaps and musculocutaneous flaps,by anatomosis with the microsurgery technique, repairs the serious and complicated soft tissue defects of shank, which can shorten course and salvage the damaged limbs.
