Objective To treat calcaneal fracture with plate fixation combined with 64-slice CT 3D reconstruction and to analyze the efficacy.Methods Totally 86 patients with Sanders Ⅲ and Ⅳ types of calcaneal fractures underwent surgical treatment,and 64-slice CT 3D reconstruction was used to record the length,height,width,Bohler angle and Gissane angle of calcaneus before and 1 d,2 d,3 d and 1 a after the treatment.Postoperative evaluation was executed based on AOFAS Ankle Hindfoot Scale.Results All the fractures healed,of which,there were 60 ones scored as excellence,19 ones in good condition and 7 ones in satisfactory condition with the excellence and goodness rate being 91.9％.Complications occurred in 4 patients,with 3 cases of delayed healing and one case of infection.Tbere were obviously differences between the lengths,heights,widths,Bohler angles and Gissane angles before and after the treatment,while the differences were not significant between the measured values 1 d and 1 a after the treatment.Conclusion 64-slice CT 3D reconstruction is an excellent clinical auxiliary tool,and is of great value for fracture typing,operational plan preparation,postoperative evaluation and late efficacy assessment.

The localization of adrenocorticotropin(ACTH),secretogranin Ⅱ in rat pituitary gland Was studied by using specific antisera in conjunction with double immunofluorescence staining techniques.Stainings with secretogranin Ⅱ serum showed intense cytoplasmic reaction in the anterior lobe of the pituitary gland.Double immunofluorescence staining was used to identify the cells that expressed secretogranin Ⅱ and ACTH.Confocal laser scanning microscopy revealed that ACTH existed simultaneouslywith secretogranin Ⅱ in quite a number of cells.The results indicate that secretogranin Ⅱ is expressed in corticotrophs of rat pituitary gland,its physiological role may be associated with the regulation of optimal pH in the secretory vesicles for the cleavage of ACTH from its precursor.

Objective To explore the mechanism of percutaneous laser disc decompression (PLDD) for treating prolapse of intervertebral disc. Methods 15 rabbits were divided into 3 groups randomly: sham group, model group with PLDD treatment, model group without PLDD treatment. The nerve conduction velocity (NCV) of L6 nerve root and the activity of phospholipase A2 (PLA2) in the intervertebral disc of L5-6 were determined 2 weeks after the initial surgery. Results NCV in the group with PLDD was significantly faster than that in the group without PLDD (P<0.001); NCV in the group without PLDD was significantly lower than that in the sham group (P<0.001). The activity of PLA2 in the group with PLDD was significantly lower than that in the group without PLDD (P<0.001); The activity of PLA2 in the group without PLDD was significantly higher than that in the sham group (P<0.001). Conclusion The activity of PLA2 in the herniated discs is higher than that in normal discs, which result in NCV falls remarkably. The PLDD can reduces chemical factors such as PLA2.

ObjectiveTo investigate the association of complement C3 with clinical and serological features of patients with systemic lupus erythematosus.MethodsData was collected by the same methods in the past ten years in fifteen hospitals in Jiangsu Province and then data weres summarized for retrospective analysis.Clinical and laboratory data were selected and then analyzed by Chi-square test,Wilcoxon rank sum test and Logistic regression.ResultsOne thousand four hundred and five patients were investigated.One thousand and forty two had low serum complement C3 level.In this case control study,hospitalization age,disease course,admission times,pleurisy,gastrointestinal involvement,general lymphadenopathy/hepatosplenomegaly,white blood cell count, haemoglobin level,platelet count, serum C-reactive protein level,serum albumin level,serum creatinine level,Urine protein quantification,anti-nuclear antibodies (ANA),anti-dsDNAantibodies, anti-SmantibodiesandSLEDAIscore were possible factors associatedwith complement C3 reduction(P＜0.05).Logistic regression analysis showed that CRP (OR=0.396,0.254-0.617,P=0.000),ANA (OR=2.907,1.267-6.670,P=0.012),urine protein level(OR=1.702,1.043-2.779,P=0.033) and SLEDAI score (OR-0.930, 0.886-0.975,P-0.003) were correlated with complement C3 reduction.Conclusion Complement C3 level is valuable for lupus flare assessment.The complement C3 reduction is a risk factor for renal impairment.

Objective To investigate the initial manifestation and disease onset feature of systemic lupus erythematosus(SLE) in the past ten years in fifteen hospitals in Jiangsu Province.Methods Data was collected by the same Methodsin all the participated hospitals and then it was summarized for retrospective analysis.Two groups were compared by chi-square test.Results ① One thousand nine hundred and fifty eight patients were investigated and the male-to-female ratio was 1∶15.0.② One thousand seven hundred and ninty eight patients had clear initial manifestations.The most common initial manifestations were skin and mucosal lesions(769 cases,42.8％ ) and arthritis (697 cases,38.8％ ).The main skin lesion was malar rash (706 cases).Arthritis was found to be more common in female than male.③ All hospitalized patients at their first admission showed multiple organ/system involvement:the most common involvement was skin and mucous membrane (82.3％),hematologic damage (74.0％),in which at least one series of blood cells were involved,arthritis (1156 cases,56.5％ ) much more than myositis (51 cases),proteinuria 1046 cases and hematuria in 385 cases.Renal biopsy pathology showed type Ⅳ glomerulonephritis.Conclusion ① SLE patients are mainly female and the male to female ratio is 1∶15.0.② The most common initial manifestations are skin and mucosal lesions.③ The most commonly involved organ/system are skin and mucous membrane,blood,joint and kidney.The most common pathological changes shown in renal biopsy is type Ⅳ glomerulonephritis.

Objective To explore the relationship between the impairment of hematological system and disease activity,immunological parameters,and the prognosis of systemic lupus erythematosus (SLE).Methods The clinical and laboratory data of in-patients with SLE in Jiangsu Province were investigated and all patients were hospitalized between 1999-2009.The impairment of hematological system was assessed and the relationship between hematological system damage and disease activity,immunological parameters,mortality rate of patients with SLE were analyzed.Statistic method used was X2 test.Results One thousand nine hundred and fifty eight cases of SLE were included in the study,in which,1836 were female and 122 were male.One thousand five hundred and forty nine (79.1%) patients complicated with hematological system damage,62.3% were anemia,45.5% with leucopenia and 29.4% with thrombocytopenia.There were significant differences in hematological system damage rate among patients with mild activity group,moderate activity group,severe activity group and almost no activity group,compared respectively with almost no activity group.The P values were P=0.01 and P＜0.01 respectively.The incidence of hematological system damage in elevated ESR,low complement C3 level,anti-dsDNA antibody group was higher than that in patients who had normal ESR,complement C3 level and anti-dsDNA group.(P＜0.01).During follow-up,166 patients died,of which the mortality rate(91.6%) in patients had hematological system damage,was obviously higher than those without hematological damage(8.4%)(P＜0.01 ).Among the 166 deceased patients,38.6% died of severe infection,22.9% died ofrenal failure,15.1% died ofnervous system damage,10.2% died of cadiovascular damage and 13.3% died from other causes.Conclusion Hematological system is one of the most commonly involved system in patients with SLE,of which anemia is the most common,and the incidence of leukopenia follows.The impairment of hematological system is closely related to lupus activity.Patients with abnormal immune parameters tend to have secondary hematological system damage.Severe infection is the main cause of death in patients with lupus,followed by nervous system damage and kidney damage.The mortality rate in patients with lupus that complicated hematological system damage is higher than patients who have no hematological system damage.
