Objective To retrospectively evaluate the mammographic features of breast ductal carcinoma in situ (DCIS)and DCIS with small invasive foci,and to analyze the correlation between the mammographic findings and the prognostic biologic factors.Methods The mammographic examination was performed in 95 consecutive women with breast DCIS(n = 50)and DCIS with invasive foci(n = 45 ).The prognostic biologic factors including progesterone receptor(PR),C-erbB-2,and p53 were evaluated in 62 of 95 cases.Categorical data were expressed as percentages and analyzed by using the X~2 test,and furthermore the odds ratio was measured.Results(1)Only one abnormality was seen on mammography in 62 patients. Combined two abnormalities on mammography were seen in 26 patients.Mammograms were normal in 7 patients.(2)Calcifications with or without other abnormality were noted in 62 cases.Of them,73% (n =45)had higher probability of malignancy calcifications and the others were intermediate concern calcifications.Clustered calcifications(36 lesions)was the most common distribution,which usually accompanied by another abnormality.And then were segmental(18 lesions)distributed pattern.As far as the shape of mass (n = 22)was concerned,the oval shaped lesion(13 cases)was the most common,and the margin of the mass appeared as ill-defined in 15 eases,microlobulated in 1,circumscribed in 4,and obscured in 2,respectively.Isodensity mass had a higher frequency in this group(12/22,55%).Other non-calcification findings included architecture distortion(7 cases),local asymmetry (15 cases),global asymmetry (5 cases),and solitary dilated duct (3 cases),and most of them accompanied with other signs. (3)For expression profile of the biological factors,significant differences were found among malignant calcification group,intermediate concern calcification group,and non-calcification group. The odds of PR positive for the lesions noted as non-calcification were 11.00 times higher (X~2 =8.571 ,P=0.003 ;95% CI, 1.998—60.572)than the lesions noted as intermediate concern calcifications,and 8.80 times higher (X~2 = 9.748,P=0.002 ;95% CI,2.024—38.253)than the lesions noted as malignant calcifications.The odds of C-erbB-2 positive for the lesions showed as malignant calcifications were 12.35 times higher (X~2=7.353, P=0.007 ;95% CI,1.447—105.443)than the lesions showed as non-calcification,and 5.74 times higher (X~2=4.977,P = 0.026;95% CI,1.110—29.645)than the lesions showed as intermediate concern calcifications.Conclusion The mammographic features of DCIS and DCIS with small invasive foci were characteristic.Mammographic findings could be a prognostic markers,which could provide a possibility for making a treatment plan.

Objective To summarize the causes of patients with fever of unknown origin (FUO) and to analyze the relationship between infectious diseases and FUO,in order to provide envidence for experiential therapy.Methods Clinical data of 374 FUO inpatients at He'nan Provincial People's Hospital from June 1,2009 to May 31,2013,including gender,age,diagnosis and department were analyzed retrospectively.Results Three hundred and twenty-seven cases among the overall 374 FUO patients (87.4％) were eventually etiological diagnosed based on supplementary examinations or diagnostic treatment.As for the causes of fever,209 were infection,accounting for 55.9％,among which 78 cases (20.9％) were diagnosed with tuberculosis,23 cases (6.1％) brucellic diseases,19 cases (5.1％) rickettsia infection.Meanwhile,the noninfectious diseases,such as connective tissue diseases (47,12.6％),hematonosis (37,9.9％) as well as the solid tumors (13,3.5％) also constituted considerable shares of the causes for FUO.However,the causes of 47 cases (12.6％) were not identified before discharge.Conclusions Infectious diseases are the main cause of FUO,in which tuberculosis accounts for the majority.Brucellosis and rickettsia infection also account for a considerable proportion.The causes of most FUO cases could be identified through detailed analysis of clinical data and supplemental examinations.

OBJECTIVETo explore the clinical effects of Mobi-C cervical artificial disc replacement (CADR) and anterior cervical decompression and fusion (ACDF) in treating single cervical disc herniation.

METHODSFrom June 2009 to June 2012, the clinical data of 27 patients with single cervical disc herniation were retrospectively analyzed. There were 18 males and 9 females, aged from 30 to 62 years old with an average of 46.7 years. Of them, 12 patients were treated with CADR (CADR group) and 15 patients with ACDF (ACDF group). All patients had pain and numbness in neck, shoulder and upper limbs, and courses of disease was from 1 to 13 months with an average of 2.4 months. The data of clinical evaluation and questionnaire survey about quality of life were collected before operation, postoperative at 1 week and final follow-up. Odom criterion was used to evaluate postoperative effect. Visual analogue scale (VAS) was used to record pain levels. Neck disability index (NDI) and health questionnaire SF-36 were used to assess the quality of life.

RESULTSNo complications about nerve and blood vessel were found and the patients were followed up from 6 to 30 months, with an average of 16 months. One week after operation, 10 cases got excellent results and 2 good in CADR group; 5 cases got excellent results and 10 good in ACDF group; there was significant difference between two groups (P<0.05). At final follow-up, 10 cases got excellent results and 2 good in CADR group; 12 cases got excellent results and 3 good in ACDF group; there was no significant difference between two groups (P> 0.05). Pain of upper limbs had obviously relieved between two groups at 1 week after operation and final follow-up (P<0.05). VAS of neck and NDI in CADR group had decreased respectively from preoperative 3.58±0.79, 23.42±6.36 to 0.58±0.51, 5.42±1.68 at 1 week after operation (P<0.05); but the index in ACDF group was no obvious at 1 week after operation. At final follow-up, VAS of neck and NDI and SF-36 score were obviously improved than preoperation (P<0.05) between two groups.

CONCLUSIONMobi-C CADR retains the movement unit in the decompression segment and can quickly recover normal action for patients. Using CADR method has a good curative effect in the early phase, and the clinical effect is reliable, may improve the quality of life.

This study aims to investigate the relationship between odor and contents of the chemical compounds in Lonicera japonica, including chlorogenic acid, galuteolin and polyphenols. High performance liquid chromatography (HPLC) was applied to determine the contents of chlorogenic acid and galuteolin in L. japonica. The ponptent of polyphenols was determined by UV-Vis Spectrophotometry. Electronic nose was used to extract and measure the odor of L. japonica. Then SPSS 17.0 software was employed for data processing. There is a significant positive correlation between the comprehensive index value of aroma and the contents of chlorogenic acid and polyphenols. The regression equations have been established. However, the relationship between the comprehensive index value and the content of galuteolin is not obvious. This is proof that the odor of L. japonica has close connection with the chemical compounds. Therefore, this research offered a new method for initially determine or predict the content of the chemical composition in L. japonica,

OBJECTIVETo investigate the effects of hydrogen sulfide (H₂S) on oxidative stress and endoplasmic reticulum stress (ERS) in a rat model of diabetic cardiomyopathy (DCM).

METHODSThirty male SD rats were randomly divided into control group, diabetes group and treatment group( n = 10). Intraperitoneal injection of streptozotocin was utilized to establish a rat model of DCM. The rats with DCM in treatment group were intraperitoneally injected with NaHS solution. After treated for 12 weeks, the hearts isolated from rats were perfused on a langendorff apparatus. The ventricular hemodynamic parameters were measured. The ultrastructures of myocardium were observed using electron microscopy. The content of malondialdehyde (MDA), the activities of superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) in myocardial tissue were determined by spectrophotometry. The expressions of C/EBP homologous protein( CHOP), glucose-regulated protein 78 (GRP78) and Caspase 12 at mRNA level in myocardium were detected using RT-PCR.

RESULTSCompared with control group, the cardiac function and myocardial ultrastructure were damaged obviously in diabetic rats. In myocardial tissue, the content of MDA was increased, while the activities of SOD and GSH-Px were decreased. CHOP, GRP78 and Caspase 12 mRNA expressions were increased significantly. Compared with diabetes group, cardiac function and myocardial ultrastructure damage were improved in treatment group. The content of MDA was decreased, while the activities of SOD and GSH-Px were increased significantly. The mRNA levels of CHOP, GRP78 and Caspase 12 were increased.

CONCLUSIONH2S can protect myocardium in diabetic rats, maybe it is related to reduce oxidative stress damage and inhibition of the ERS-induced apoptosis pathway.
