Objective To investigate the safety and efficiency of large-dose alcohol sclerotherapy in treating simple hepatic cyst. Methods Patients with hepatic cyst were divided into two groups. One group with 49 patients was treated with small-dose (<80 ml) absolute alcohol instillation. The other one with 32 patients was treated with large-dose (≥80 ml) absolute alcohol instillation. Blood alcohol concentration (BAC) was recorded right after and 30 rain, 1 h,2 h,3 h after the treatment. Diameter of cyst as a parameter of efficiency was recorded and compared between two groups during 1 year follow-up visit. Results Large-dose group was significantly more efficient in treating hepatic cyst than small-dose group. All BAC records were within the safe range and below the legal limit after drinking. BAC reached its peak 30 minutes after the treatment began and then decreased gradually. A significant correlation was found between BAC and the alcohol dosage. Conclusions Ultrasound-guided sclerotherapy with repeated large-dose absolute alcohol instillation is a safe and efficient treatment for simple hepatic cyst from the perspective of BAC.

Objective To investigate spinemagnetic resonance imaging(MRI) findings in patients with axial spondyloarthritis (SpA) and to analyze the correlation between imaging and clinical manifestation.Methods The clinical data of patients with axial SpA were recorded.All patients underwent whole spine MRI scanning.The MRI findings of spinal involvement were explored.Moreover,the correlation between lesions in spinal MRI and Bath Ankylosing Spondylitis Disease Activity Index(BASDAI),Bath Ankylosing Spondylitis Functional Index (BASFI),Bath Ankylosing Spondylitis Metrology Index (BASMI),nocturnal pain visual analogue scale (VAS) score,back pain VAS score,global disease activity VAS score,Ankylosing Spondylitis Disease Activity score (ASDAS),erythrocyte sedimentation rate,C-reactive protein was analyzed.Results Thirty-three patients with axial SpA were included in this study.The image abnormalities of the spine were confirmed in 29 axial SpA patients by MRI,including Romanus lesion,Andersson lesion,the inflammation of facet joints and syndesmophyte.In correlation study,BASMI was positively correlated to the numbers of acute Romanus lesions,chronic Romanus lesions,chronic Andersson lesions and whole spinal lesions(r =0.440,P＜0.05; r =0.483,P＜0.05; r=0.421,P＜0.05; r=0.589,P ＜ 0.05 respectively).There was a statistically significant correlation between chronic Andersson lesions and BASFI(r =0.392,P ＜0.05).But no significant associations were found between MRI lesions and other clinical findings.Conclusions MRI lesions in axial SpA were associated with findings reflecting the spinal function,which can better guide the clinical treatment.

Objective To analyze the clinical and pathological characteristics of children with lupus nephritis(LN).Methods The data of 116 inpatients from Mar.2000 to Nov.2008 with LN were retrospectively analyzed.The clinical,immunochemical and pathological data were recorded.Renal tissue was observed by light microscopy and electron microscopy after HE,PAS,Masson and PASM staining according to WHO standards.Follow-up results showed complete remission,partial remission,disease activity,renal insufficiency and death.Results Of the 116 cases of LN,there were 27 male and 89 female with a ratio of male to female 1.03.3,and the mean age was(12.0?2.2) years.The incidence of nephrotic syndrome was 63.8 %(74 cases),and acute nephritis was 21.5%(25 cases).Class Ⅳ LN was the most frequent type(14 cases,50%) and classⅢ was next(25 cases,21.5%).In view of the outcome,rapidly progressive glomerulonephritis and class Ⅳ LN were the worst.LN was initially controlled in 96.5% of the patients.Relapses of LN were most caused by the intermittent treatment.Totally 32 cases showed different renal injury,and 6 cases progressed to death.Conclusions Renal biopsy is important to diagnosis,treatment and prognosis evaluation of LN.Long and regular treatment is important for children with LN.

OBJECTIVETo explore methods of treating middle and distal tibia nonunion with the treatment of advanced bone graft combined with locking compression plate.

METHODSFrom January 2011 to December 2012, 12 patients with middle and distal tibia nonunion were treated with advanced bone graft combined with locking compression plate. Among patients, there were 8 males and 4 females aged from 20 to 69 with an average of 47 years old. The time from first injuries to bone nonunion was from 9 months to 5 years, avergaed 19 months. Four cases were treated with external fixation, 6 cases were treated with plate fixation, 2 cases of 12 patients occurred broken of plate and nail. Eleven patients were non-infective bone nonunion and 1 patient was infective bone nonunion. Preoperative X-ray and CT showed all patients had sequestration and formation of ossified bone with different degrees. Operative time, blood loss, wound healing were observed, fracture healing time was evaluated by postoperative X-ray. Johner-Wruhs scoring standards was used to evaluate ankle joint function after operation at 10 months.

RESULTSOperative time ranged from 90 to 185 min with an average of (125.00±20.15) min; blood loss ranged from 225 to 750 ml with an average of (415.00±120.00) ml. All patients were followed up from 10 months to 2.5 years with an average of 1.5 years. Postoperative X-ray showed bone union was formed around fracture after operation at 4 months in all patients, 3 cases obtained bone healing within 6 months after operation, 9 cases obtained from 8 to 12 months. No infection, injury of nerve and vessles, and broken of plate and nail were ocurred. According to Johner-Wruhs scoring at 10 months after operation, 10 cases obtained excellent results, 1 good and 1 moderate.

CONCLUSIONAdvanced bone graft combined with locking compression plate, which can build fracture multi-point supporting based on full compression of bone nonunion to get effective fixation, is an effective method in treating middle and distal tibia nonunion.

Objective To investigate the blockade effects of soluble PD-1 (sPD-1) expressed in vivo on B7-H1/PD-1 signal transduction,and inhibitory effect in pulmonary metastasis of melanoma with combi- nation of Hsp70-B16 antigen peptides in mice.Methods The pulmonary metastasis model of melanoma was established in mice.Immunohistochemical staining and flow cytometry were utilized to detect the expres- sion of PD-1 and B7-H1 respectively in pulmonary metastasis loci.Four days after the inoculation of tumor cells,forty murine models of pulmonary metastasis were randomly divided to be immunized with normal sodium (group A),empty vector pcDNA3.1 (group B),PDlA plasmid (group C) respectively via tail vein injection,subcutaneous injection of Hsp70-B16 antigen peptides (group D) or with the combination of intra- venous PDlA plasmid and subcutaneous Hsp70-B 16 antigen peptides (group E).The local infiltration with lymphocytes in pulmonary metastasis loci was observed and a series of immunological parameters were assessed 17 days after the inoculation of tumor cells.Results The melanoma pulmonary metastasis model was successfully established.There were a lot of PD-1 positive cells in these loci,and B7-H1 molecule was massively expressed on the surface of B16 cells in metastasis loci.The pulmonary metastasis was inhibited in the mice of group E,and the inhibition rate was 95%,higher than that in other groups (53%,76%,9% in group C,D,B,respectively).The quantity of CD8~+ T cells in pulmonary metastasis loci,cytotoxicity of spleen lymphocytes to tumor cells,and serum concentration of IL-2 and IFN-?were all significantly elevated in the mice of group E as compared with those of other groups (all P

Objective To evaluate the specificity and limitations of sacroiliac joint magnetic resonance imaging (MRI) in the diagnosis of axial spondyloarthritis (SpA)in patients with chronic low back pain.Methods We retrospectively analyzed clinical data of 390 patients with chronic low back pain in Department of Rheumatology,the PLA General Hospital from January 2013 to December 2015,including clinical manifestations,laboratory examinations and MRI data of sacroiliac joints.Results There were 238 men and 152 women recruited.A total of 326 cases were diagnosed as axial SpA,including 216 men and 110 women with mean age (27.10 ± 8.64) years and mean duration (7.64 ± 3.50) months.Among these 326 patients,243 (74.5％) were HLA-B27 positive.The other 64 patients were considered as diagnoses rather than SpA (non-SpA),consisting of 22 men and 42 women with mean age (31.29 ± 7.76) years and mean duration (5.75 ±2.90)months.Non-SpA group had 10 (15.6％) patients with HLA-B27 positive.There were 68.1％ and 65.0％ SpA patients showing bone marrow edema and bone erosion of sacroiliac joint in MRI imaging respectively.Although there were 25.0％ non-SpA patients with bone marrow edema and 7.8 ％ with bone erosion in MRI of sacroiliac joint,the scores of bone marrow edema 0.00 (0.00,0.75) and bone erosion [0.00(0.00,0.00)] were significantly lower compared with those in axial SpA group [bone marrow edema scores 2.00 (0.00,4.00),bone erosion scores 1.00 (0.00,3.00);P ＜ 0.05].The scores of fat infiltration [1.00 (0.00,4.25),1.00 (0.00,4.00)] and bone sclerosis [0.00 (0.00,1.00),0.00(0.00,1.75)] were not statistically different between two groups.Diagnostic sensitivity of bone marrow edema and bone erosion for axial SpA were 56.4％ and 64.1％ respectively,specificity were 93.8％ and 92.2％ respectively.The positive predictive value of bone marrow edema and bone erosion for axial SpA were 9.09 and 8.21,negative predictive value were 0.46 and 0.38.Diagnositic sensitivity of fatty infiltration and bone sclerosis for axial SpA group were 29.1％ and 57.7％,specificity were 64.1％ and 46.9％.The positive predictive value of fatty infiltration and bone sclerosis for axial SpA were 0.81 and 1.08,negative predictive valne were 1.10 and 0.90.Conclusion Sacroiliac joint MRI is a valuable method to diagnose axial SpA in patients with chronic low back pain.Yet it still has some limitations.Clinical presentations and spinal MRI would be helpful in some patients.

OBJECTIVETo explore the effect of Chinese herbal medicine Baotai Granule (BTG, a self-made preparation) on CD antigen blocking efficiency, prolactin (PRL) and progesterone (P) in patients with recurrent spontaneous abortion (RSA).

METHODSThirty-four women suffered from RSA were treated with BTG, twice every day, 1 package (10 g) in each time by orally intake. Changes of the efficiency of serum blocking antibody in them to the CD antigen in their husband's peripheral T-lymphocytes before and after treatment were observed. And the changes of blood levels of PRL and P were also monitored.

RESULTSFetus had successfully protected in 30 women (88.2%), in them, the efficiency of blocking to CD3, CD4 and CD8 after treatment were all higher than that before treatment, and levels of PRL and P in peripheral blood increased along with the increase of gestational age, while no obvious change was found in those who failed to complete pregnancy.

CONCLUSIONChinese herbal medicine could protect the fetus by regulating the response between endocrine and immunity network during pregnancy.
