In pregnant women,positive rate of thyroid peroxidase antibody(TPOAb) is approximately 3%~10%.It is still controversial whether thyroid antibody positive rate is higher in women undergoing artificial assistant reproductive technologies.TAI might have a negative effect on pregnant outcome,which has been proved in different groups of women.Intravenous immunoglobulin,thyroxin replacement therapy and selenium therapy have been used for TAI intervention.More evidence is needed to demonstrate mechanism and evaluate effect for each therapy.

Prostate cancer is a common malignancy that affects men's health in the Western countries. Single nucleotide polymorphisms (SNPs), as the third generation of genetic markers, can influence the development, progression, and prognosis of prostate cancer. The same SNP may be related differently with prostate cancer among different races. This paper describes the relationship between SNPs and prostate cancer according to their related genes. SNPs can predict the risk of prostate cancer as well as the possible adverse reactions in its treatment, but at present they do have some limitations.

BACKGROUND:Transplantation of mesenchymal stem cells (MSCs) to multiple sclerosis (MS) is a new developed treatment to be given more and more attention.However,whether the MSCs function by cell replacement after going cross the blood-brain barricr or immune suppression needs further confirmation.OBJECTIVE:To establish a steady and effective method of Y chromosome in situ hybridization (ISH) and to detect the distribution of MSCs in a mouse model with MS.DESIGN,TIME AND SETTING:The observational study was performed at the Laboratory of Molecular Immunology,Institute of Healthy Science from September 2007 to February 2009.MATERIALS:A total of 30 C57BL/6 mice,aged 6-8 weeks and weighing 15-20 g,were selected.Female mice were used to establish experimental autoimmune encephalomyelitis (EAE).METHODS:Y chromosme specific DNA probe labled with digoxine (DIG) was designed and ISH was performed to confirm that the designed probe was Y chromosome specific and biologically sensitive.We transplanted the MSCs from male mice into the female EAE mice,and tracked the MSCs by Y chromosome ISH.MAIN OUTCOME MEASRUES:Distribution of MSCs in mice with EAE was observed under the optical and fluorescence microscope.RESULTS:The probe was confirmed to be Y chromosome specific and biologically sensitive.What's more,a steady and effective method of ISH was established.Some MSCs were detected in the periphery organs-spleen and lymph node of mice with EAE;seldom in spinal cord which indicated that MSCs might play its roles by immune suppression.CONCLUSION:Some MSCs were detected in the periphery organs-spleen and lymph node of mice with EAE,but seldom in spinal cord in the central nervous system.

There are many subjects related to anesthesiology and the band between anesthesiology and clinical practicevery is close. So students can not be proficient in anesthesiology by traditional teaching methods. The use of three-dimensional case teaching method in anaesthesiology teaching is a good attemptment. three-dimensional case teaching method integrate case method, multimedia technology and clinical case. It can help medical students analyze and solve clinical problems, improvetheir academic performance and enhance their clinical basic skills.

Background and purpose:Histological grade of DCIS is an important factor in the prognosis, high nuclear grade have higher inifltration trend and recurrence rate. This study aimed to evaluate the dynamic and morphological MRI charactristics of ductal carcinoma in situ (DCIS) of the breast, then analyze its relations with nuclear grade. Methods:Of the 94 patients, 97 lesions were proved DCIS by pathology. The morphology, maximum size, time-intensity curve of lesion were recorded or measured. Statistic was performed to identify MR imaging features that optimally discriminated HNG from non-HNG DCIS. Results:There were 49 non mass-like enhancement lesions, and 48 masses enhancement lesions. Among 49 non mass-like lesions, 29 were segmental enhancement (59.18%). Dynamic enhanced performance:50 exhibited plateau curves and 27 were washout curves. BI-RADS categories:22 BI-RADS 4A, 19 BI-RADS 4B, 29 BI-RADS 4C, and 27 BI-RADS 5. HNG lesions exhibited larger mean maximum lesion size (non-mass-like enhancement: P=0.01; mass: P=0.03), time- intensity curve was variable to approach signiifcance (P=0.01), and BI-RADS can help to discriminate the nuclear grade (P=0.02). There were no differences in lesion morphology (P>0.05). Conclusion:The preliminary ifndings suggest that DCE MR imaging features may aid in identifying patients with high risk DCIS.

Objective:To analyze ultrasonic and clinical manifestation of noncompaction of the ventricular myocardi‐um (NVM) in order to guide clinical early diagnosis and treatment .Methods :Echocardiographic manifestations of 36 NVM patients were observed .Combined with electrocardiogram (ECG) ,cardiac MRI and coronary angiography (CAG) etc .,clinical manifestations of NVM were comprehensively analyzed .Results:Multiple coarse trabecular muscles and deep crypts among them were founded in heart chamber in all cases .Color Doppler showed that blood flow inside the crypts communicated with blood flow in heart chamber ,there were 33 cases (91.6% ) of left ventri‐cle type and three cases (8.4% ) of right ventricle type .Different types of abnormal ECG existed in all cases and at‐rial fibrillation occupied the largest proportion (50% ,18/36) .Some MRI results were accorded with those of ultra‐sound .In most cases ,CAG didn′t show coronary stenosis .Conclusion : Echocardiography is most convenient and effective examination ,which can provide important basis for diagnosis and treatment of noncompaction of ventricular myocardium .

Objective To explore the clinical characteristics and prognostic factors of breast carcinosarcoma.Methods Clinical data of 37 breast carcinosarcoma patients treated at Tianjin Cancer Hospital from 1974 to 2014 was analyzed retrospectively.Kaplan-Meier unvariate analysis was used to calculate the survival rate and compare the survival rates.Multivariate factors for survival were analyzed by COX proportional hazards regression model.Results 37 cases of breast carcinosarcoma were all female.The median age was 55 years.Among them 31 cases complained for painless mass,six cases had breast mass with skin ulceration.21 cases were three-negative breast cancer.Ten cases had axillary lymph node metastasis,ten cases had distant metastasis.The 5-year survival rate was 62.3％.Unvariate analysis showed that axillary lymphnodes metastasis (P =0.045) and therapeutic schedule (P =0.016) significantly influenced the oulcome of the patients.COX multivariate analysis validated that the therapy modality was an independent prognostic factor for breast carcinosarcoma(P =0.041).Conclusions Breast carcinosarcoma is rare and has a poor prognosis.ER,PR and HER-2 expressions in most cases are negative.If there is axillary lymph node metastasis,the prognosis is poor.A reasonable and comprehensive treatment can improve the prognosis.

OBJECTIVETo investigate the technique and its effect of combined nasolabial flap and free auricular composite flap for full-thickness nasal alar defect.

METHODSFrom March 2010 to March 2013, 9 patients with full-thickness nasal alar defects were treated with combined nasolabial flaps and free auricular composite flaps. Composite auricular flap was used as inner lining and cartilage framework. The nasolabial flap at the same side was used as outer lining.

RESULTSAll the patients were followed up for 6-18 months (average, 12 months). All the 9 composite auricular flaps survived completely. Epidermal necrosis happened at the distal end of 1 nasolabial flap. Alar rim was almost normal and symmetric nose was achieved in 6 cases. The arc and the thickness of the alar rim was not enough in 3 cases, resulting in asymmetric appearance.

CONCLUSIONSThe survival area of auricular composite flap can be enlarged with nasolabial flap. The auricular helix edge can be reserved to reconstruct nasal alar rim with smooth and natural arc. Large full-thickness nasal alar defedts can be reconstructed with combined nasolabial flaps and free auricular composite flaps.

OBJECTIVETo evaluate the safety and clinical outcomes of the novel simplified no-flip surgical approach to Shang Ring male circumcision in adults.

METHODSA total of 528 adult males, aged 18 - 58 (mean 35) years, 63 with phimosis and 465 with redundant prepuce, underwent no-flip Shang Ring circumcision with or without removal of the outer ring. The operation time and intraoperative blood loss were recorded and observations were made on such complications as postoperative bleeding, infection, edema, and wound dehiscence.

RESULTSThe operation time, intraoperative blood loss, and 2-hour postoperative pain score were (3.8 +/- 0.3) min, (0.6 +/- 0.1) ml, and 7.3 +/-0.3, respectively. Spontaneous ring detachment occurred at 21.6 +/- 2.1 days postoperatively in 12.7% of the patients (67/528) who had chosen not to remove the rings. Of those who preferred removal of the outer ring (87.3% [461/528]), none experienced any pain at the ring removal 7 days after the operation. Postoperative complications included infection in 3 cases (0.56%) and mild edema in 9 (1.70%), but no bleeding and wound dehiscence. Totally, 518 (98.1%) of the patients felt satisfied with the postoperative penile appearance.

CONCLUSIONNo-flip Shang Ring circumcision, with no need for removal of the inner ring, is a safe and simple approach for adult males, which is superior to conventional Shang Ring circumcision for requirement of fewer surgical instruments, shorter operation time, lower incidence of complications, and better satisfaction with the penile appearance. However, these advantages are to be further demonstrated by more randomized controlled trials.

OBJECTIVETo explore early clinical effect of acetabular cup in total hip replacement for the treatment of Crowe II developmental dysplasia of hip.

METHODSEighteen patients (18 hips) with Crowe type II developmental dysplasia of hip were treated with total hip replacement from September 2001 to July 2013. Among them,including 13 males and 5 females aged from 42 to 60 years old with an average of 47.6 years old; the courses of diseases ranged from 9 to 22 years with an average of 13.5 years. All the patients had hip joint pain, limb shortening and limited hip function before operation. Harris score of hip joint were used to evaluate recovery of function at 1 day and 12 months after operation. Prosthetic coverage of acetabular cup at 1 week after operation was observed by using radiography.

RESULTSEighteen patients (18 hips) were followed up from 12 to 24 months with an average 17 months. All incisions were healed at stage I. No deep vein thrombosis, hip dislocation, periprosthetic joint infection and prosthesis loosening were occurred. No revision surgery during follow-up period. Prosthetic coverage of acetabular cup was more than 80% at 1 week after operation. Harris score were increased from 42.67 ± 5.06 before operation to 94.79 ± 3.27 at 12 months after operation (t = -45.269, P < 0.001).

CONCLUSIONFor type Crowe II developmental dysplasia of hip patients, 15° face-changing acetabular cups in THR could obtain higher actebular component coverage rate and satisfactory early clinical effects.
