ObjectiveTo investigate the value of high-frequency ultrasound in assessment of the therapeutic efifcacy of traditional Chinese medicine in patients with breast dysplasia using.MethodsFrom March to September in 2014, 50 patients with breast dysplasia in the Third Affiliated Hospital of Beijing University of Chinese Medicine were enrolled in the study. In addition, they were treated with Xiaozheng pills. Before and after treatment, these patients were examined using ultrasound. The thickness of the breast gland layer in each patient was measured. When the dilated ducts lactiferous, cysts, hypoechoic areas, or nodules of the breast were detected, the diameter or volume was measured or calculated. A grading system of the breast dysplasia was used to evaluate the disease degree, and the quadrants of the breast dysplasia were counted. The thickness of the breast gland layer, the volume of cysts and nodules, the diameter of hypoechoic areas and the dilated ducts lactiferous, the number of the breast dysplasia were compared with the pairedt-test. The grading of the breast dysplasia was compared with rank sum test.ResultsThere were significant decreases in the thickness of the grand layer, the diameters of the ducts lactiferous and the hypoechoic area after treatments [(15.92±4.73) mm vs(13.02±4.20) mm,t=2.240,P<0.01; (2.26±0.58) mm vs (1.71±0.47) mm,t=5.202,P<0.01; (21.14±5.57) mm vs(17.80±4.63) mm,t=5.529,P<0.01]. However, there were no significant differences in the volume of cysts and nodules. The grading of the breast dysplasia showed statistical difference (z=-5.667,P<0.01), and the number of the breast dysplasia quadrants was reduced markedly (5.38±1.85 vs3.28±1.97,t=7.566,P<0.01).ConclusionsUltrasound can be an effective method in assessment of patients with breast dysplasia treated with the traditional Chinese medicine. The assessment can be based on some signs, including the thickness of the grand layer, the diameters of the ducts lactiferous, and the diameters of the hypoechoic area. The grading system and breast quadrants counting in these patients may be added as supplementary criteria to make a complete therapeutic evaluation.

Objective To evaluate the interactive relationship between inflammation detected by single photon emission computed tomography combined with computed tomography (SPECT/CT) and magnetic resonance imaging (MRI) detection of synovitis,bone marrow edema (BME) in the early rheumatoid arthritis (RA) patients.Methods Twenty patients with early RA were included into this study.All patients were diagnosed based on the 2010 ACR/EULAR classification criterion.Patients' unilateral hands (MCP 2-5 and PIP 2-5 joints) were inspected by SPECT/CT (label:99Tcm-MDP) and MRI (3.0 T).SPECT/CT and MRI images were analyzed by two reviewers blinded to other clinical information.Increased bone metabolism of the regional area of interest (ROI) was analyzed and the uptake ratio was calculated.MRI quantitative evaluation was completed by RAMRIS score system.Statistical analysis was performed using SPSS 17.0 software.Student's t-test,analysis of variance (ANOVA),x2 test and post-hoc analysis (Scheffe) were used for comparison of datas,correlation analysis was carried out with Spearman rank correlation test.Results Twent ypatients with a total of 160 joints were examined.MRI examination revealed synovitis (39,24.4％),or BME (24,15.0％) in 63(39.4％) joints.99Tcm-MDP uptake increased in 79(49.4％) joints,and the uptake ratio was higher than normal joints (1.59±0.26 vs 1.15±0.09,t=6.408,P＜0.01).The uptake ratio between the graded synovitis level and RAMRIS synovitis score had a moderate correlation (r=0.535,P=0.001).The uptake ratio of BME level and BME score was well correlated (r=0.765,P=0.001).Conclusion In early RA patients,MRI is sensitive for synovitis and BME.SPECT/CT can detect early abnormal bone metabolism associated with inflammation,which is more sensitive than MRI.SPECT/CT can be used to detect changes of RA at the molecular level.Compared with synovitis,BME is more closely related to bone metabolism changes,which may suggest that BME may play a major role in the bone destruction in RA.However,further studies are needed to verify this hypothesis.

0.05), but the yields of four-year-old and five-year-old Dahuaye and Wuguangye samples were significantly higher than that of Xiaohuaye sample (P0.05).

OBJECTIVE By analyzing the high risk factors for pulmonary fungus infection in intensive care units of neurosurgery,this paper may be regarded as a good reference for early diagnosis and treatment. METHODS According to the domestic diagnostic standard on pulmonary fungus infection,we analyzed the clinical data of 58 patients with pulmonary fungus infection in department of neursurgery. RESULTS Totally 117 strains of fungi were isolated from the 58 cases.Candidiasis was the most frequent type,accounting for 92.3%.Some factors,such as the severity of underlying diseases,long-time coma,long-term use of broad-spectrum antibiotic,abuse of glucocorticoid,the open airway and some traumatic intubations might be regarded as the high risk factors for pulmonary fungus infection.Fluconazole showed good clinical effects on the treatment of fungus infection. CONCLUSIONS It is important to eliminate the high risk factors for pulmonary fungus infection,to provide early diagnosis and to use prophylactic antifungal agent,which can reduce the incidence rate of pulmonary fungus infection.

Objective This study is aimed to assess the accuracy of clinical measurement of remission and investigate the association between clinical remission and the ultrasound imaging assessment of synovitis and infla'mation and to explore the value of ultrasound imaging in the evaluation of disease activity in the tight control of rheumatoid arthritis (RA).Methods RA patients with a disease activity score in 28 joints (DAS28-ESR) ≤2.6 for at least 3 months were stratified-using a standard and more stringent DAS28 and simplified disease activity index (SDAI) remission thresholds and the corresponding clinical and ultrasound imaging measures of synovitis were recorded.In addition,a retrospective analysis of disease activity in patients was carried out.Mann-Whitney U test,x2 test and multi-factor analysis of variance of repeated measurements were used for statistical analysis.Results A total of 48 cases were recruited.Thirty-seven cases (77％) met the ACR remission criteria,29 cases (60％) fulfilled the SDAI remission criteria,and 32 (67％) cases reached 2010 ACR/EULAR Boolean-based definition of remission criteria.There was no significant differences on imaging disease activity between SDAI remission patients and those who were not in remission (GS score,P=0.38; PD score,P=0.32).Seventy-nine percent patients in SDAI remission had GS and/or PD activity,but the difference was not statistically different when compared with patients who did not reach SDAI remission (P=0.29).Sustainable remission obtained in patients who also had achieved image remission could have longer remission time (P＜0.01) Conclusion Using more stringent clinical remission criteria could help in reducing residual inflammatory activity of,but ultrasound PD activities may not be significantly reduced.Integrated clinical indicators such as physical examination and imaging tools such as ultrasound can provide more accurate assessment of disease activity and could be used to guide treatment to achieve trueremission.

To explore the protective effect of sodium tanshinone IIA sulfonate (STS) on microcirculatory disturbance of small intestine in rats with sepsis, and the possible mechanism, a rat model of sepsis was induced by cecal ligation and puncture (CLP). Rats were randomly divided into 3 groups: sham operated group (S), sepsis group (CLP) and STS treatment group (STS). STS (1 mg/kg) was slowly injected through the right external jugular vein after CLP. The histopathologic changes in the intestinal tissue and changes of mesenteric microcirculation were observed. The levels of tumor necrosis factor-α (TNF-α) in the intestinal tissue were determined by using enzyme-linked immunoabsorbent assay (ELISA). The expression of intercellular adhesion molecule-1 (ICAM-1) in the intestinal tissue was detected by using immunohistochemisty and Western blot, that of nuclear factor κB (NF-κB) and tissue factor (TF) by using Western blot, and the levels of NF-κB mRNA expression by using RT-PCR respectively. The microcirculatory disturbance of the intestine was aggravated after CLP. The injury of the intestinal tissues was obviously aggravated in CLP group as compared with S group. The expression levels of NF-κB p65, ICAM-1, TF and TNF-α were upregulaed after CLP (P<0.01). STS post-treatment could ameliorate the microcirculatory disturbance, attenuate the injury of the intestinal tissues induced by CLP, and decrease the levels of NF-κB, ICAM-1, TF and TNF-α (P<0.01). It is suggested that STS can ameliorate the microcirculatory disturbance of the small intestine in rats with sepsis, and the mechanism may be associated with the inhibition of inflammatory responses and amelioration of coagulation abnormality.

Objective Tumor size discrepancy in measurement between real-time ultrasonic elastography and conventional uItrasound(US) was found in some breast lesions.The study was designed to investigate the value of the feature in the diagnosis of breast cancer,and its relationship with the margin features on gray-scale US.Methods Both US and real-time elastogram using a Hitachi EUB-8500 US system were performed in 308 consecutive Datients.The margin features on US and the size measured on both methods were documented.A lesion was defined as a significant size discrepancy when a larger size measured at elastogram.Sensitivity,specificity,and overall accuracy of feature to diagnosis malignancy were determined by surgical pathology as gold standard.Results There were total 166 benign,163 malignant and 3 borderline lesions.of 99 lesions with larger measurement on elastography,there were 91 malignant lesions and 8 benign lesions.By the feature of size discrepancY,the sensitivity,specificity and accuracy was achieved 55.8%,96.9%,75.7%,respectively.The size measured on elastogram was statistically larger than that on gray scale US(t=-11.0,P＜0.05).The ratio of indistinct,angular and spiculated margin characteristics were significantly higher in breast cancers with larger size measurement than those with unchanged or decreased size measurement(P＜0.05).Conclusions The increased size-measurement at elastography is helpful to diagnosis breast cancers.And it is more likely to be present in breast cancers with indistinct,angular or spiculated margin.

OBJECTIVETo summarize clinical results of the microdecompression for the treatment of intraforaminal lumbar disc herniations.

METHODSFrom September 2005 to May 2013,16 patients( 12 males, 4 females)with intraforaminal lumbar disc herniations underwent microdecompression, ranging in age from 32 to 56 years old with a mean of 38.6 years old. The lumbar disc herniations were located at L(3,4). in one patient, L(4,5) in 10 cases and L5S1 in 5 cases.

RESULTSAll the patients were followed up, and the duration ranged from 20 to 48 months, with a mean period of 36 months. According to Macnab evaluation, 12 cases got an excellent result, 4 good. No apparent complications related to the technique occurred. Satisfactory clinical results were obtained in this series.

CONCLUSIONMicrodecompression may be particularly useful in the treatment of intraforaminal lumbar disc herniations. The microdecompression procedures are more likely to be well tolerated by older patients.
