Objective To study the cause, prophyl ax is and management of the complications of laser treatment for varicose veins of the lower extremity. Method From Sep 2003 to Dec 2004, 52 patients (65 limbs) underwent endovenous ablat ion procedures. The laser was introduced into the vein to achieve venous occlusi on. Results Postoperative complications included ecchymosis in 12 cases, skin burn in 14 cases, saphenous nerve injury in 7 cases, thrombophlebitis in 3 cases, and subcutaneous fat liqu idation and infection in 2 cases. Most of the complications subsided after sympt omatic treatment in 2 to 3 weeks. Conclusion Most complications of laser treatment for varicose veins are transient and self-healing.

Objective To observe the neuroprotective effect of atorvastatin and its influence to tumor necrosis factor-alpha(TNF-α) and intedeukin-10(IL-10)in intraeerebral hemorrhage(ICH)rats,and to explore the possible mechanism of its neuroproteetive effect.Methods ICH WaS induced by stereotaxic infusion of collagenase into the right baSal ganglia,the expressions of TNF-α,IL-10 in the serum and brain tissue were analyzed by enzyme linked immunosorbent assay(ELISA),HE staining was used to evaluate the number of activated microglia.Results (1)The numbers of activated mieroglia,TNF-α and IL-10 were have significant differences between group A and group B(all P＜0.05).(2)In comparision with group B,numbers of activated mieroglia in group C,D and E were significantly redueed(P＜0.05).Atorvastatin cause a dose-dependent regulation,which decreased the level of TNF-α and inereased the level of IL-10 significantly(all P＜0.05).Conclusion The down-regulation of TNF-α and up-regulation of IL-10 might partly attribute to the neuropmtection of atovastatin.

Objective To study the changes of serum protein spectrum in patients with systematic lupus erythematosus (SLE) in order to screen specific protein markers. Methods Serum samples from 72 patients with SLE and 85 age- and sex-matched controls were assessed using surface-enhanced laser desorp-tion/ionization time-of-flight mass spectrometry (SELDI-TOF-MS) with weak cation exchange (CM10) pro-rein chip. Forty samples from the patients and 50 control samples were randomly selected to serve as a pre-liminary training set; significantly different protein peaks were automatically chosen for the system training and development of a decision classification tree model. The validity of the model was then challenged with a blind test set (including another 32 samples from patients and 35 from human controls). Results A total of 73 effective protein peaks were detected within the mass/charge ratio (m/z) interval 2000 - 50000, among which, 15 protein peaks significantly differed between patients with SLE and controls (P < 0.01). Three pro-tein peaks with an m/z value of 4001, 6305 and 7356 were automatically chosen as a biomarker pattern in the training set that discriminated patients with SLE from controls with a sensitivity of 90.0% (36/40), speci-ficity of 92.0% (46/50) and accuracy rate of 91.1% (82/90). When the SELDI marker pattern was tested with the blinded test set, it yielded a sensitivity of 87.5% (28/32), specificity of 91.4% (32/35) and accuracy rate of 89.6% (60/67). Conclusions SELDI-TOF-MS protein chip could be used to screen serum protein for SLE, and the decision classification tree model with these biomarkers may favor the diagnosis of SLE.

Objective To observe the clinical efficacy of staphylococcal protein A immunoadsorption plus nonmyeloablative chemotherapy with CD34+ autologous peripheral blood stem cell transplantation in the treatment of refractory systemic lupus erythematosus (SLE). Methods Three patients with active SLE were enrolled into this study. All patients were diagnosed with lupus nephritis by renal biopsy and poorly responded to routine therapy. Before transplantation, patients were given 6 sessions of immunoadsorption apheresis using columns of staphylococcal protein A-silica with an interval of 3 days; each session processed 3 L plasma and a total of 18 L plasma was processed over the 6 treatments. Three days following the immunoadsorption apheresis, the mobilization of stem cells was realized by intravenous cyclophosphamide at a dose of 2 g per square meter of body surface area and subcutaneous recombinant human granulocyte colony-stimulating factor (G-CSF) at a dose of 5 g per kilogram of body weight per day for 5 days. Then, peripheral blood raonoclonal cells were obtained by CS-3000 Cell Separator, and passed through the Clini Macs CD34+ cell selection device, with the final concentration of CD34+ cells being 2.6×106, 2.1×106 and 2.4×106 per kilogram of body weight respectively, and that of CD3+ cells being 3×105, 2.1×105, and 2.0×105 per kilogram of body weight, respectively, in these three patients. The conditioning regimen consisted of oral fludarabine of 50 mg/d for 5 days plus intravenous pig anti-human thymocyte immunoglobulin (ATG) at a daily dose of 90 mg/kg for 5 days. After 72-hour treatment with ATG, the frozen stem cells were infused back to the patients. Clinical manifestations and lupus-correlated immune parameters were compared in patients at baseline and after transplantation. Results Following immunoadsorption apheresis, an obvious decrease was observed in the level of serum anti-dsDNA, antinuclear antibody and IgG antibodies, while an increase in the level of serum complement 3. All patients achieved the reconstruction of hemopoiesis 2-3 days after the transplantation. Also, an apparent clinical remission was achieved with the SLEDAI score being less than 3. Six months after the transplantation, serum anti-dsDNA and antinuclear antibodies as well as urine protein were undetectable, the level of complement 3 reached the normal range, and renal function was restored. Conclusions Staphylococcal protein A immunoadsorption plus nonmyeloablative CD34+ autologous peripheral blood stem cell transplantation are effective and safe for refractory SLE, but the long-term effect remains to be connfirmed by further studies.

Objective To analyze the clinical and immunological manifestations of antiphospholipid syndrome(APS)in a cohort of 100 patients.Methods The clinical and serologic features of APS(Sapporo preliminary criteria)in 100 patients were analyzed retrospectively.Results The cohort consisted of 79 female patients and 21 male patients witb a mean age of 36?13 years at diagnosis.Primary APS was presented in 37% of patients;APS was secondary to systemic lupus erythematosus(SLE)in 46%,lupus-like syndrome in 14%. Eighty percent of the patients had thrombosis,43(54%)patients had venous thrombosis,18(22%)had arterial thrombosis,15(19%)had both arterial and venous thrombosis.4(5%)had thrombosis of microcirculation. Forty-two(52%)patients presented thrombosis at a single site,26(32%)at two sites,12(15%)at three or more sites.Forty-five(56%)patients experienced one thrombotic episode,20(25%)patients had only one re- currence,and 15(19%)had more thrombosis.The most common manifestations of thrombosis were deep vein thrombosis(36%),pulmonary embolism(30%)and stroke(26%),with heart,kidney,gastrointestinal tract and other organs involvements.Thirty-four(51%)female patients had spontaneous fetal losses including intrauter- ine fetus death and recurrent spontaneous abortion.Seventy-one(71%)patients developed thromboeytopenia. The presence of antieardiolipin antibody(ACL)was detected in 84 patients(84%).Among 90 patients with APS,alone ACL was detected in 38 patients(42%),both ACL and lupus anticoagulant(LA)were detected in 36(40%),LA alone in 16(18%).Patients with APS associated with SLE or lupus-like syndrome had higher frequency of arthritis,leukopenia,antinuclear antibodies(ANA)and low complement levels.Female patients had a higher frequency of leukopenia,ANA and ACL.Male patients had a higher prevalence of deep venous thrombosis in the lower limbs and LA.Conclusion APS is an autoimmune disorder characterized by recurrent arterial and venous thrombosis,fetal loss,or thrombocytopenia with the presence of ACL and/or LA.In APS secondary to with SLE,the patient's sex can modify the disease expression and define specific subsets of APS.

Anti-glutamic acid decarboxylase antibody-associated encephalitis is a kind of autoimmune encephalitis mediated by anti-glutamic acid decarboxylase antibody, which belongs to anti-neuronal intracellular synaptic protein antibody-associated encephalitis. Clinical manifestations include stiff-person syndrome, cerebellar ataxia, limbic encephalitis, seizures, etc., often associated with a variety of autoimmune diseases, rarely associated with tumors. Detection of anti-glutamic acid decarboxylase antibody is crucial for clinical diagnosis. Immunotherapy helps to relieve symptoms and improve prognosis. The incidence of this disease is low, and there are few reports at home and abroad. This paper intends to review the research on this encephalitis, hoping to improve the clinicians′ understanding and the level of diagnosis and treatment of the disease.

Objective To summarize and analyze the relationship between exposure to rabies and its prevalence in Jurong City from 2003 to 2007,and discuss further the possible solutions to it.Methods The data of people vaccinated after being biten by animals were collected,manipulatd,and analyzed,with their illness records dealt with accordingly from 2003 to 2007 in Jurong City.Results Not a single one of 21 596 cases was that of rabies with proper treatment in the last 5 years.The sex ratio was 1.47∶1.The highest probability of exposure was the preschoolers under the age of 10.The disease occurred throughout the year,with the peak in July and September.Those biten by dogs accounted for 86.85% of the exposure to rabies,and among them,people biten by domesticated animals were in the majority.Wounds by the domesticated dogs reached 74.60%.Not a single case was treated properly among the 9 rabies cases reported in the same period.Conclusions Strengthening the management of domesticated dogs,publicizing the knowledge of rabies,treating the wound properly and thoroughly,innoculation with vaccine from the very beginning and administering rabies immune globulin are the effective ways to prevent rabies.

Objective To explore the effectiveness of sandplay therapy combined with family counseling in children with school phobia and its influence of child′ self-consciousness. Methods Integrative sandplay therary with family consulting were used to treat 28 patients with school phobia regularly for 2 months. Sandplay and family consulting therapy were given once a week for 45 minutes . Clinical outcomes were assessed using CGI-GI and Piers-Harris children′s self-consciousness scale before and after treatment as well as 3 months posttreatment. Results Overall response rate was 85%. In addition, the physical appearance and characteristic factor before and after treatment were no significant difference (P>0.05). The rest of the various factors and total score compared with pre-treatment significantly improved (P<0.05). After treatment for 3 months, every factor in self-consciousness of children and total score were no significant difference (P>0.05). Conclusion Integrative sandplay therapy with family counseling has better and long-lasting treatment effect to self-consciousness of children with school refusal.

Objective To discuss the clinical value of application of three-dimensional reconstruction technique of MSCT in examination of colonic tumours.Methods Thirty patients underwent scanning using helical CT and post-processing on the workstation.All CTC images were reconstructed using shaded surface display (SSD) on workstation.Perspestive images such as the ones from DCBE were generated via raysum.The images could clearly demonstrate the extent and detail of the disorder by adjusting the CT value threshold.These results and that of barium enema and colon endoscopy were compared.Results Thirty cases had completely clinical and pathological data.3D images could correctly reveal the macroscopic morphology of colon tract and location of lesions.The correctly diagnostic rate was 100％ by MSCT,while the diagnostic rate by CTVE and colon endoscopy was basicly identical.Conclusion With the utilization of multiple methods,3D reconstruction can effectively demonstrate colonic tumours,and can be applied routinely in examination of colonic tumours.
