Ultrasound guided microwave ablation of thyroid nodular goiter and cystadenoma: A single center, large cohort study.

ABSTRACT: Thyroid nodules are one of the most common entities that affect the thyroid gland. Traditionally, their treatment was surgery. Currently, ablation combination with percutaneous procedure became a good option.To analyze safety, efficacy, and describe our experience in microwave-ablation using ultrasound-guidance for benign thyroid nodules.A total of 304 patients with 1180 thyroid nodules (thyroid cystadenoma and nodular goiter) were studied retrospectively. Two hundred sixty-seven patients who underwent microwave-ablation successfully in our hospital were enrolled in this study. The baseline, follow-up nodule volume, thyroid function tests, thyroid antibodies, and posttherapy complications were analyzed. The informed written consent was obtained from patients or guardians. The study was approved by the ethics committee of our hospital.The average age was 50.1 ±â€Š11.7 (21-83 years), 214 were women (80.1%) and 53 (19.9%) were men. The average number of nodules per patient was 4.02 ±â€Š1.8 (1-8), 9.86%, 6.13%, and 84% located in the right thyroid lobe, left lobe, and bilateral, respectively. The average size of the nodules was 5.28 cm2 ±â€Š3.63 (0.09-23.45 cm2). The average ablation time was 11 minutes ±â€Š5.36 (3-20 minutes). The hospitalization period was 24 hours ±â€Š10.16 (7-48 hours). Eighteen complications were reported. Postablation volume reduction rate was 54.74% and 93.3% at 3 and 12 months follow-up respectively (P < .05). The thyroid function tests, pre and postablation showed no significant changes (P > .05).Ultrasound-guided microwave-ablation of thyroid nodules is safe and effective. More clinical trials are needed to define the true use of microwave-ablation.

Clinical comparative analysis of Laparoscopic transabdominal preperitoneal repair and path tension -free ;hernioplasty in the treatment of recurrent inguinal hernia in adults / 中国基层医药

Objective To compare the clinical efficacy of laparoscopic repair of laparoscopic transabdominal preperitoneal(TAPP)and Lichtenstein tension-free repair herniorrhaphy in the treatment of recurrent inguinal hernia in adults,and to explore the clinical advantages of TAPP in the treatment of recurrent inguinal hernia.Methods A retrospective analysis was conducted in 54 adult patients with recurrent inguinal hernia from December 2010 to January 2015.The patients were randomly divided into TAPP group and Lichtenstein group.The operation time,intraoperative bleeding volume,postoperative hospitalization time,cost of hospitalization,postoperative complications,early postoperative pain and the recurrence of hernia were compared between the two groups.Results All patients were successfully completed surgery.The operation time of TAPP group (47.2 ±9.4)min was significantly shorter than (73.1 ±10.4)min of Lichtenstein group (t=-2.503,P=0.034).The median amount of bleeding during operation of TAPP group was 40(15 -110)ml,which was significantly less than 73(11 -130)ml in Lichtenstein group (t=-6.018,P=0.000). Postoperative hospital stay of TAPP group[(6.5 ±1.4)d]was shorter than (8.2 ±1.6)d of the Lichtenstein group (t=-2.613,P=0.028).Early postoperative pain score of TAPP group[(1.8 ±1.2)points]was better than (2.9 ± 1.4)points in Lichtenstein group (t=-7.006,P=0.000),the difference was statistically significant.However,the hospitalization cost of TAPP group[(8 842.8 ±415.2)yuan]was higher than (6 676.9 ±327.6)yuan of the Lichtenstein group,the difference was statistically significant(t=6.782,P<0.05).In TAPP group,2 cases had complications after operation,which were less than 5 cases of Lichtenstein group.Postoperative follow up ranged from 6 to 48 months,1 case of recurrence in Lichtenstein group,the recurrence rate was 3.8%.There was no recurrence in the TAPP group.Conclusion TAPP has the advantages of short operation time,less bleeding,rapid postoperative recovery,less postoperative pain and so on.It can be used as a recommended procedure for the treatment of recurrent inguinal hernia in adults.

Analysis of postoperative pain in laparoscopic transabdominal preperitoneal and Lichtenstein repair of adult recurrent inguinal hernia / 中国医师进修杂志

Objective To investigate the causes and prevention of postoperative pain of laparoscopic transabdominal preperitoneal (TAPP) and Lichtensteinrepair in the treatment of adult recurrent inguinal hernia.Methods Sixty adult recurrent inguinal hernia patients were enrolled in this study.They were divided into TAPP group and Lichtenstein group by random digits table,with 30 cases in each group.At 6 h Mter operation,the pain degree was evaluated by visual analogue scale (VAS) and compared between two groups.The level of VAS in TAPP group was (3.76 ± 1.47) scores,in Lichtenstein group was (6.36 ± 1.54) scores,and there was significant difference (t =-5.978,P =0.000).In TAPP group,pain was mainly moderate (17 cases,56.67％) and mild (11 cases,36.67％).In Lichtenstein group,pain was mainly moderate (14 cases,46.66％) and severe (13 cases,43.33％).Postoperative follow-up ranged from 6 to 48 months.No chronic pain appeared in TAPP group.There were 4 cases with chronic pain in Lichtenstein group,and the incidence rate of chronic pain was 13.3％.Conclusions The operation of TAPP in the treatment of recurrent inguinal hernia in adult patients has the advantage of shorter operation time,less postoperative pain,faster postoperative recovery,and can effectively reduce the incidence of postoperative pain.

Development and Application of the Reverse Genetic Technologies for Infectious Bursal Disease Virus / 病毒学报

Infectious bursal disease virus (IBDV) is an important member of the Birnaviridae family. IBUV mainly targets the bursa of Fabricius, the central immune organ of chicken, resulting in chicken infectious bursal disease (IBD). IBD represents one of the great challenges for ongoing development of the poultry industry. Reverse genetics for IBDV emerged over twenty years ago. Since then, the technologies behind virus rescue have continually improved leading to a deep understanding of IBDV gene function and tailored vaccine development. Our lab has also been instrumental in the field of IBDV research. Here we review studies on the pathogenic mechanism and the effective prevention and control of IBD.

Screening proteins interacting with infectious bursa disease virus Gt VP2 from cDNA library of B lymphoid cells of the bursa of Fabricius / 生物工程学报

To screen the interactive proteins with IBDV Gt VP2 protein from cDNA library of B Lymphoid cells of the bursa of Fabricius. The expression cDNA library plasmids was transformed to the yeast competent cells, which have the bait plasmid-Gt VP2. After testing for growth in synthetic complete medium lacking histidine and uracil and for production of beta-galactosidase (X-gal), we obtained 16 positive clones. We searched the gene sequences of positive clones in the NCBI website. The blast results showed that five positive clones were the gallus sequences. They were Gallus gallus breed mitochondrial DNA, O_G1cNAc transferase, Tumor protein p53 binding protein, Stathmin and Chondroitin sulfate Ga1NAcT-2, respectively. This study is helpful for the further identifying the receptors of IBDV in B Lymphoid cells of the bursa of Fabricius.
