Objective To study the corelation of mucosal involvement and corticosteroid dosage in the control of bullous pemphigoid(BP). Methods One hundred and three in-patients with bullous pemphigoid hospitalized during 1988 - 2002 were retrospectively analyzed for their mean corticosteroid dosage for controlling the disease and the duration for complete relieving the skin lesions, as well as the duration to start corticosteroid tapering. All the patients were divided into two groups: group A (37 cases) with mucosal involvement and group B (66 cases) without mucosal involvement. Results The mean corticosteroid dosage used to control the disease in group A was much higher than that in group B (t = 3.488, P 0.05). Conclusion Patients with mucosal involvement require a higher dosage of corticosteroids to control the disease.

Objective: To observe the changes of heart rate and the contents of angiotensin Ⅱ(AngⅡ) in blood plasma in ventricular tachycardia(VT) rats with electro-acupuncture(EA) on ‘daling’(PC7). Methods: 40 SD rats were randomly divided into normal, model, treatment and control groups with 10 cases in each. VT model was duplicated by inject CsCl in femoral vein. To observe the rats’ electrocardiogram (ECG) and record their heart rates. EA was applied to‘daling’ (PC7) on treatment group and applied to‘Taiyuan’ (LU9) on control group for 5 minutes. Then, we detected the contents of AngⅡ in the rats’blood plasma respectively. Results: The heart rate and contents of AngⅡin rat increased obviously in model group were (547?30) time/min and (353.21?49.12)pg/mL). They restored to the normal state after EA ‘daling’ (PC7) are(474?25)time/min and(268.44?47.49)pg/ mL.But the effect was not obvious in ‘Taiyuan’ (LU9). Conclusion VT rat heart can be prompted to restore to the normal state after EA ‘daling’(PC7); AngⅡ played an important role in VT.

Purpose To investigate the imaging features of lumbar spinal epidural angiolipoma, and to improve the imaging diagnostic capability of the disease. Materials and Methods Four patients with lumbar spinal epidural angiolipoma confirmed by pathology were recruited in the study. CT and MRI images were reviewed and the imaging characteristics including the shape, size, location, density, and signal intensity were analyzed. Results The lesions located at the right front of the spinal canal in two cases, at the left front in one case, and the residual one case located directly behind the spinal canal. The longitudinal axis of the lesions paralleled to the longitudinal axis of the spine. The dura mater spinalis was compressed and inward shifted. All of the four cases showed homogeneous iso- or hypo-density on CT without calcification or necrosis in the lesions. The maximum diameter was 3 to 5 cm. The boundary was clear and smooth. Three lesions showed dumbbell-shaped and crossed foramen, but the adjacent bone were not absorbed or destructed. One lesion showed scallop-like. On MRI, four cases displayed slightly hypointense on T1WI and hyperintense on T2WI. On STIR images, the lesions showed hyperintense with patchy low signal intensity in it. The boundary of the lesions was clear. After administration of contrast media, two lesions presented remarkably homogeneous enhancement, one lesion showed dual tail sign, and one lesion displayed pen-tip-like at the both ends. Conclusion MRI plays an important role in locating the lesion and distinguishing internal tissue components of spinal angiolipoma, which is the gold standard for the diagnosis of the tumor. CT provides excellent supplement. The Combination of CT and MRI will improve the diagnostic accuracy of the spinal angiolipoma.

Objective Metabonomics method based gas chromatography-mass spectrometry (GC/MS)were used to analyze the urine samples of patients with hyperlipidemic pancreatitis (HLP) to describe the characteristics of metabolism changes of HLP,identify potential biomarkers,and investigate the role of metabonomics study in the management of AP.Methods 24 patients of HLP and 40 age,sex matched volunteers were enrolled and their urine samples were collected.The urine samples underwent preparation,derivation and GC/MS analysis,Orthogonal-Projection to Latent Structures-Discriminant Analysis (OPLS-DA)were performed to detect the metabolic profile difference between the HLP and control group.Results HLP patients can be precisely distinguished from healthy controls.21 metabolites (credibility ＞ 700 ) were identified using the reference compounds available in the libraries of NIST and Wiley.It was identified that levels of nicotinic acid,aconitie acid,citric acid,hippurie acid,hydroxyphenylacetic acid,hydroxyphenylpropionicacid were decreased,while the levels of tryptophan,tyrosine,tyramine,16-hexadecanoic acid,18octadecanoie acid were increased.It was also suggested that there was change in tricarboxylic acid cycle and gut bacterial flora,as well as fat metabolism and metabolism of amino acid.Conclusions There are differences between healthy controls and HLP patients in the term of GC/MS metabolic profiling,and the biomarkers in the metabolites could be found through metabonomics analysis,and the mechanisms of the metabolic changes could be explored.It was noted that the research of metabolites in the urine samples may be a useful tool to help diagnose and understand the pathogenesis of HLP.Metabonomics analysis is a promising research method.

Objective To compare the clinical results of percutaneous compression plating (PCCP)and Trigen short reconstruction intramedullary nail for intertrochanteric hip fractures. Methods During 2005 and 2008, the patients suffered with AO/OTA Al and A2 intertrochanteric hip fractures were divided into two groups; 36 fractures were treated with PCCP and 48 fractures with Trigen short reconstruction nail.During an average of (16.3±3.2) months follow-up, clinical evaluation involved visual analogue scale(VAS)score for pain in the 1st week, the 1st month, the 3rd month, the 6th month and the 12th month, and a Harris hip score one year post operation. Radiographs were examined for fracture healing-time, displacement scale of the neck screws and fracture impaction scale. All the complication in both groups was recorded. Results There were no difference in blood loss and operation time in both groups. The postoperative pain was significantly lower in the PCCP group in the initial three months after the surgery. Larger scale of fracture impaction and screw telescoping were seen in PCCP group. Also shorter healing time, higher Harris score results were achieved in PCCP group than those of Trigen short reconstruction nail group. Four peri-implant fractures occurred in Trigen short reconstruction nail group, which included one in the greater trochanter and three in the femoral shaft, but only one case need revision for bone displacement. In PCCP group, it was found that the superior neck screw was slightly displaced for tendency to cut-out in one patient. Conclusion Both PCCP and Trigen short reconstruction intramedullary nail can be successfully used to treat Al and A2 intertrochanteric hip fractures with minimal invasive technique. And the PCCP showed more rapid pain relief and bone healing, easily bony reduction and fewer complications.

Objective To analyze the therapeutic effect of Masquelet technique in the treatment of bone defects.Methods From January 2008 to December 2014,20 patients with bone defects were treated by Masquelet technique.There were 15 males and 5 females,from 18 to 69 years of age (average,38.4 years).Four cases had open bone defects and 16 infectious ones.At the first stage,radical debridement of the bone defects and soft tissue was conducted via conventional approaches.The bone defects ranged from 2 to 9 cm,averaging 6.1 cm.At the second stage,internal fixation was applied in 18 cases and external fixation in 2.The interval from the second stage to the first stage operation ranged from 6 to 23 weeks (average,11.5 weeks).The healing of bone defects and the functional recovery of adjacent joint were evaluated by Paley scoring at the last follow-up.Results The 20 patients were followed up for 12 to 50 months (average,19.7 months) after the second stage operation.All the patients obtained uneventful wound healing and control of infection after the first stage operation except the one with infectious defects who had to receive 2 operations to control the infection at the first stage operation.At the second stage operation,obvious injury and defect of the induced membrane occurred in 4 cases.All the patients achieved clinical healing of bone defects after 3 to 6 months (average,4.8 months).The bone defect healing was graded as excellent in all.After bone healing,all the patients resumed weight-bearing activities,with no breakage or infection of fixators,or recurrence of infection.By the Paley scoring at the last follow-up,the functional recovery of the adjacent joint was excellent in 8 cases,good in 10 and fair in 2,yielding an excellent and good rate of 90.0％.Conclusion As a kind of modified free bone grafting,Masquelet technique has advantages of simplicity,limited complications,a high rate of healing,and good control of bone infection.
