Objective To analyze the MRI features of fibrocystic breast disease (FBD). Methods 39 patients with pathologically proven FBD were retrospectively reviewed. The imaging protocol consisted of pro-contrast imagings and bilateral breast volume im-aging for breast assessme NT(VIBRANT). MRI features were interpreted based on the morphologic and enhancement kinetic de-scriptors defined on ACR DIRADS-MRI lexicon. Results There were 3 types on ACR BI-RADS-MRI lexicon in FBD,including 13 focal mass-type showing malignant enhancement kinetic pattern mostly;15 cyst-type with non-enhancement or mild enhance-ment,of them,1 case with periductal mastiffs showing strong enhancement and rapid up-slope and wash-out mimicking a breast cancer. 6 non-mass type usually showing benign enhancement kinetic pattern. In 5 patients,MRI did not show definite abnormal evi-dence. Conclusion MRI is of significant value in diagnosing FBD.

Objective To investigate the characteristics of vena cava connection in patients with asplenia syndrome diagnosed by ultrasound. Methods From October 2009 to February 2014, 49 patients with asplenia syndrome diagnosed in Fuwai Hospital by ultrasound were included in this study. The characteristics and percentage of varied types of anomalous connection of vena cava and pulmonary vena were analyzed. Results Thirty patients (61.2%) had bilateral superior vena cavies. In these cases, right vena cava was drainage into right atrium (or the right side of the single atrium), while left superior vena cava into left atrium (or the left side of the single atrium). For hepatic vein, drainage into inferior vena cava were found in 25 patients (53.2%), into left atrium (or the left single of the single atrium) in 1 patient (2.1%), into right atrium (or the right side of the single atrium) in 3 patients (6.3%), into both right and left atrium in 5 patients (10.2%) and into the middle of the single atrium in 1 patient (2.1%). For inferior vena cava, drainage into left atrium (or left side of the single atrium) were found in18 patients (36.2%), into right atrium (or right side of the single atrium) in 24 patients (51.1%) and into the middle of the single atrium in 1patient (2%). Total anomalous pulmonary venous drainage occurred in 20 patients (40.2%) and partially anomalous pulmonary venous drainage in 8 patients (16.3%). Conclusion Asplenia syndrome is frequently accompanied with anomalous vena cava and pulmonary venous drainage.

Objective To determine whether mutation of Hepatitis B virus (HBV) X gene is associated with hepatitis B virus-associated glomerulonephritis (HBV-GN).Methods The venous blood was collected from 50 patients with HBV-GN and 60 patients with asymptomatic HBV carriers (control group).Serum HBV DNA was extracted to determine the serum titer of HBV-DNA and then polymerase chain reaction (PCR) was used to detect the HBV X gene mutation.Results (1)There were not statistical significance between age and gender in HBV-GN group and control group (P ＞0.05).There were not statistical significance of serum replication level of HBV DNA in HBV-GN with X gene mutation and control group (P ＞ 0.05).Urine protein excretion in HBV-GN group with or without X gene mutation was found with statistical significance (P ＜ 0.05).(2)Nucleotide mutations [84％ (42/50)] resulted in amino acid substitution in HBV-GN.Nucleotide mutations changed in transfunction control region of X gene,including position nt1653,nt1726,nt1727,nt1730,nt1753,nt1762 and nt1764.(3)Nucleotide mutations [8％(5/60)] resulted in amino acid substitution in control group.Nucleotide mutations changed in position nt1632 and nt1635,located in non-functional region.Conclusions HBV X gene mutations and the subsequent amino acid substitutions are found in HBV-GN.The urine protein excretion level increases in patients with X mutation,suggesting that these mutations may play an important role in the pathogenesis of HBV-GN.

A highly sensitive immuno-PCR assay based on sandwich ELISA and PCR was developed to detect the circulating antigen in trichinellosis. Antigens were purified from the muscle larvae of Trichinella spiralis, and the myeloma cells were fused with spenocytes immunized with T. spiralis antigens to product the specific monoclonal antibodies. Indirect ELISA was used to select the antibody-secreting hybrodoma cells. By this method of procedure, monoclonal antibody F4C6 against the T. spiralis ES antigen was obtained, which was used as the indicator antibody, while the rabbit polyclonal antibodies against T. spiralis were to be used as capturing antibodies. The plasmid Bluecript Ⅱ KS was amplified by PCR with biotin-labeled primer M13-20, and thus the biotin-labeled DNA was obtained. Both the second antibody and DNA labeled with biotin were to be linked with 100 ng/ml avidin. The whole procedures of assay consisted of two steps, in which the circulating antigens were captured by monoclonal antibody through sandwich ELISA in the first step, and the DNA linked by monoclonal antibody was amplified by PCR in the second step. The sensitivity of this method was compared with that of the ELISA assay. It was found that the measuring ranges to detect the circulating antigens in trichinellosis were 50 pg/L to 0.005 pg/L for the immuno-PCR assay, and 5 μg/L to 0.05 μg/L for ELISA assay, the former was quite higher than that of the latter. It is evident that this method is highly sensitive for the detection of circulating antigens in trichinellosis.

Objective To evaluate results of double eyelid operations with different incisions.Methods 100 patientswere selected randomly from out-patients that accepted double eyelid operation.Half of them were objected to double eyelid operation through a palpebral marginal incision.Incision was designed along the palpebral margin,close to boots of eyelashes.Most of the subcutaneous tissues was cut and removed,and then dermis and tarsal plate were fixed with 5 stitches of suture.About 1-3 mm wide of skin along superior margin was removed reasonably.In another 50 cases.double eyelid operation was performed with conventional incision.Incision was designed 6-8 mm far from the palpebral margin.Most of the subcutaneous tissues was removed.and then dermis and tarsal plate were fixed with 5 stitches of suture.Results Postoperative results were evaluated 5 days and 1 month after operation respectively.Postoperative double eyelid shapes were all satisfled in two groups.Swollen eyedids and scar were more inconspicuous in the cases with the palpebral-marginal incision without impairment on eyelashes.Conclusion Compared with double eyelid operation with conventional incision,blepharoplasty with palpebral margin incision has the same results but with lighter impairment,milder hydropsia and more inconspicuous scar.The key point of this procedure is the fixation of dermis and tarsal plate,keeping a good radian of double eyelid line.
