Objective:To compare transvaginal ultrasonography and hysteroscopy in diagnosis of intrauterine adhesions.Methods: One hundred and one cases of infertile women were treated by transvaginal ultrasound and hysteroscopy.Results: One hundred and one cases of infertility by hysteroscopy diagnosis of 87 cases of intrauterine adhesions, transvaginal ultrasound 68 cases of intrauterine adhesions, 78.16% sensitivity, sensitivity and different degree of intrauterine adhesions without significant difference. The diagnosis coincidence rate of intrauterine adhesions was consistent with transvaginal ultrasonography and hysteroscopy.Conclusion: In the clinical diagnosis and treatment of intrauterine adhesions, transvaginal sonography has the value of irreplaceable hysteroscopy. Vaginal ultrasonography can be used as the first choice for intrauterine adhesions.

Objective To investigate the feasibility of laparoscopic extirpation for mammary multiple fibroadenoma. Methods A total of 12 patients with multiple fibroadenoma that were diagnosed by ultrasonography and fine needle aspiration were enrolled in this study. Through an axillary small incision, the air was inflated into the retromammary space, which had been obtusely separated to build a surgical space. Then, 58 fibroadenomas were resected under a laparoscope. Frozen-section examination was carried out during the operation. Results All the masses of the 12 patients were laparoscopically extirpated successfully, without operative complications. The operation time was 40-150 minutes with a mean of 80 minutes. One month after the operation, the shape of the breast looked well and the sensation of the nipple remained normal. During a 1- to 36-month follow-up (mean 18.5 months), none of the patients had scars on the breast or tumor recurrence. All of them were satisfied with the cosmetic results. Conclusion Laparoscopic extirpation of mammary multiple fibroadenoma through the retromammary space is safe and feasible.

Atrial fibrillation (AF) is one of the common arrhythmias. Catheter radiofrequency ablation is a only effective therapeutic method of AF currently. Contact force sensing catheter like SMART TOUCH can real time monitoring the pressure of catheter tip, which can help operators to understand the contact force between atrial and ablation points, and guide the atrial fibrillation ablation. It is significantly improved the effectiveness and safety of the atrial fibrillation. This article will focus on the current situation of radiofrequency ablation for AF by contact force catheter, in order to provide guidance for clinical work.

Objective To evaluate the clinical application and safety of CT-guided transthoracic cutting needle lung biopsy in diagnosing diffuse lung diseases. Methods By using automatic biopsy gun (14 & 16 gauge), CT-guided transthoracic cutting needle lung biopsy was performed in 29 cases with diffuse lung diseases. The samples obtained were sent for pathological and immunohistochemical examination. The sampling successful rate, the diagnostic accuracy and the occurrence of complications were analyzed. Results Technical success rate was 100%, and large size of sample enough for pathological and immunohistochemical examination was obtained in all 29 cases. Definite pathological diagnosis could be made in 25 cases, with the positive diagnostic rate of 82.8%. The main complications included pneumothorax and pulmonary hemorrhage. The symptoms in most cases were not severe and disappeared within one week after the treatment. Conclusion For the diagnosis of diffuse lung diseases, CT-guided transthoracic cutting needle lung biopsy is a safe, easy, effective and reliable method with high successful rate, high diagnostic value and fewer complications, in these respects this technique is superior to transbronchial lung biopsy, open lung biopsy and video-assisted thoracoscopic lung biopsy. Therefore, this technique should be popularized in clinical practice.

Objective To evaluate the efficacy of a self-expandable metal stent coated with autologous endothelial progenitor cells(EPCs)for prevention of restenosis in transjugular intrahepatic portosystemic shunt(TIPS)in a swiue model.Methods EPCs were coated on the metal stents using fibrin gel before TIPS procedure.TIPS was performed in 15 young adult pigs,using an autologous EPC-seeded stent(treatment group,n=9)or a conventional bare metal stent(control group,n=6).All pigs were sacrificed at 2 weeks after TIPS procedure.Portography was performed immediately before the euthanasia.Gross and microscopic pathological exams and immunohistochemical exams of the TIPS track specimens were performed.Fisher test and t test were used to analyse the data.Results TIPS was performed successfully in all the 15 swine.On day 14 of follow-up,direct portography and necropsy demonstrated that 5 shunts remained patent,2 shunts stenosed,and the remaining 2 shunts occluded in the treatment group(n=9);while 5 shunts were occluded and one shunt was stenotic in the control group(n=6).The patency rate was 56%vs 0(P=0.03)between the two groups.Histological analyses showed a greater pseudo-intimal hyperplasia in the TIPS track of the control group than that of the treatment group(pseudointimal thickness at hepatic vein,hepatic parenchyma and portal vein site was(1.2±0.4),(1.3±0.5),(1.5±0.4)mmvs(1.0±0.6),(0.9±0.5),(1.0±0.4)mm respectively(P<0.05).Conclusion The EPC-coated metal stent is feasibly constructed in vitro and improves the patency in TIPS in a porcine model.

Objective To investigate the curative effect of methotrexate in treating systemic lupus erythema-tosus(SLE). Methods The chosen outpatients were divided into 2 groups,group A(28 cases) :MTX combined with small dosage of prednisone (prednlsone 10mg/d) ; group B (20 cuses) : medium dosage of prednisone (prednisone 30rag/d). Observation includes SLE disease activity index(SLEDAI) ,relapse while dosage of prednisone was reduced to small amount and drug side effects. Results The SLEDAI score of group A was reduced from (9.4±2.1) to (4.1±0.9) ,and group B from (8.6±2.5) to (4.0±1.0). Compared the result of before and after treatment be-twcen the two groups, the curative effect is obvious (P<0.01). However, there was no significant difference of efficacy between the two groups(P>0.25). While dosage of prednisone was reduced to 10mg/d ,there were 8 cases of relapse in group B,and only 3 cases in group A during the entire observation period. The difference is significant (P<0.025). The side effect of group A is gastrointestinal reaction and for B is mainly the cushing syndrome. Conclusion MTX is an effective treatment fw the light and medium activity SLE,and can reduce the dose of prednisone, prevent long-term using large dose of prednisone which will cause side effect.

Objective To research the impact of axillary limph node group dissection oriented by senti-nel lymph nodes instead of axillary dissection on upper limb lymph edema and disease -free survival ( DFS ).Methods We designed a randomized controlled research , which included 205 cases of operatable breast cancer (AJCC 7th:stage I or stage IIa)from Jan.2011 to Jan.2013.Those cases were separated into 2 groups randomly ( random number method ):group A underwent mastectomy ( or lumpectomy ) and axillary group lymphadenectomy oriented by sentinel lymph node biopsy ( SLNB) ( if positive continued for ALND ) while group B underwent mastec-tomy(or lumpectomy)and axillary lymph node dissection(ALND).All patients underwent SLNB by blue dye method and received adjuvant therapy after surgery according to National Comprehensive Cancer Network ( NCCN) guideline and Chinese anti-cancer association guideline .Results There were 101 cases in group A and 104 ca-ses in group B , but 1 case in group A was excluded for false negative of SLN.The midium follow-up was 30 months.There were no significant differences of average age , tumor size, grade, estrogen receptor (ER),proges-terone receptor ( PR) and human epidermal growth factor receptor 2 ( HER2 ) expression between the 2 groups. Group A had a lower frequency of lymph edema than group B (4.0%vs 17.3%,χ2 =9.384,P=0.002), and al-so a milder degree ( mild 2%vs 11.5%,middle 2%vs 3.8%,severe 0%vs 1.9%).There were no significant differences of upper limb sensory disorder (14.0%vs 16.3%,χ2 =0.218,P=0.641), neither of DFS(Log-Rank analysis:3-year average DFS 32.89 months vs 33.72 months,χ2 =0.186,P=0.667;Cox risk model analysis:HR=1.395,P=0.495)between the 2 groups.Conclusion Axillary group lymphadenectomy oriented by SLNB can reduce the happening of lymph edema from ALND and has a comparative effect on DFS as ALND .
