Journal of Endocrine Surgery 2012;06(2):106-108
ObjectiveTo discuss the clinical value of ultrasonically activated scalpel(UAS) in breast cancer patients who underwent 2-3 cycles of neo-adjuvant chemotherapy by comparing UAS and electric knives (EI) in modified radical mastectomy. MethodsFrom Jun.2009 to Aug.2011, 52 breast cancer patients taking 2-3 cycles of neo-adjuvant chemotherapy underwent modified radical mastectomy in our hospital. Among them, UAS group included 23 patients, and EI group included 29 patients.The 2 groups were compared in terms of the operation time, intraoperative blood loss, postoperative drainage tube duration, postoperative hospital stay, the number of lymph nodes retrieved, and the volume of subcutaneous hydrops.ResultsBetween the 2 groups, the difference of intraoperative blood loss and postoperative drainage tube duration had statistical significance(P <0.01 ).The difference of operation time, hospital stay, and subcutaneous hydrops had statistical significance ( P < 0.05 ).The difference of the number of lymph nodes retrieved had no statistical significance ( P > 0.05 ).ConclusionThere are good curative effects for breast cancer patients undergoing modified radical mastectomy by UAS and axillary lymph node dissection after neo-adjuvant chemotherapy, which is consistent with the conception of fast track surgery.

Purpose To improve the early correct diagnosis and avoid misdiagnosis of cervical mucinous adenocarcinoma.Methods Twenty-one cases of cervical mucinous adenocarcinoma were reviewed and analyzed retrospectively.The expression of CEA and Ki-67 was detected in the tumor by immunohistochemical staining (LABC method).Results Of the twenty-one cases, three cases (14.3%) were missed out, in which one was missed out by TCT and the others by biopsy; four cases (19.0%) were diagnosed by biopsy as adenocarcinoma in situ with invasion not be excluded, and then further confirmed as invasive adenocarcinoma by LEEP; one case (4.8%) was diagnosed as cervicitis at first and was further detected as adenocarcinoma by LEEP; twelve cases (57.1%) were directly diagnosed as adenocarcinoma by biopsy; one case (4.8%) was diagnosed as adenocarcinoma with unknown origin, and then as cervical adenocarcinoma after hysterectomy. Immunohistochemically, ten cases were CEA positive (47.6%) and the expression of Ki-67 was increased (>20%).Conclusions Understanding of the cytologic and histologic features of adenocarcinoma in cervix might improve its early detection and correct diagnosis, so that timely treatment is guaranteed for patients.

Congenital cataract is a highly heterogeneous disorder at both the genetic and the clinical-phenotypic levels. A unique cataract was observed in a 4-generation Chinese family, which was characterized by autosomal dominant inheritance and late-onset. Mutations in the 13 known genes (CRYAA, CRYAB, CRYBB1, CRYBB2, CRYGC, CRYBA1/A3, CRYGD, Connexin50, Connexin46, intrinsic membrane protein LIM2, cytoskeletal protein BFSP2, the major intrinsic protein-MIP and the heat shock factor HSF4) have previously been demonstrated to be the frequent reason for isolated congenital cataracts, but the exact molecular basis and underlying mechanisms of congenital cataract still remain unclear. This study was designed to find whether these 13 genes developed any mutation in the family members and to identify the disease-causing gene. Polymerase chain reaction (PCR) and direct DNA sequence analysis were carried out to detect the 13 genes. The results showed that no mutation causing amino acid alternations was found in these potential candidate genes among all patients in the family, and only several single-nucleotide polymorphisms (SNPs) were identified. A transitional mutation in the fourth intron of CRYBB2 and some silent mutations in the first exon of BFSP2 and CRYGD were found in the cataract family, but further study showed that these mutations could also be found in normal controls. It was concluded that some unidentified genes may underlie the occurrence of late-onset cataract in this family. A genome-wide screening will be carried out in the next study.

Objective To study the application value of endoscopic purse-string sutures with titanium clips and endoloops for the gastric wall defect during endoscopic full-thickness resection (EFTR). Methods Data of iffteen hospitalized patients with gastric submucosal tumor (SMT) undergone EFTR was reviewed. The patients were all applied with endoscopic purse-string sutures with titanium clips and endoloops, which was performed after the EFTR when the gastric walls were perforated artiifcially. Results The gastric tumors were complete successfully resected in the iffteen patients through endoscopic surgery, applied the purse-string sutures with titanium clips and endoloops after the EFTR when the gastric walls were perforated artiifcially. Approximately, ifve clips were utilized on average. Postoperative surgical wound healing was followed up for 6 months, no tumors recurred. Conclusion It is safe, minimally invasive treatment method for rapid rehabilitation in endoscopic full-thickness resection utilized purse-string sutures with titanium clips and endoloops.

Objective:Placental pathology reflects the health condition of both mother and fetus during pregnancy, providing information about pathogenesis especially in adverse pregnancies, and may provide guidance on subsequent pregnancies. Description on the placental changes after long-term use of rivanol is lacking, and this evaluated the placental changes, with emphasis on the differential diagnosis from other primary placental lesions.Methods:A total of 85 placentas from rivanol induced abortion submitted to the Department of Pathology, Obstetrics and Gynecology Hospital of Fudan University from Januaury 2017 to October 2019 were reviewed; and 81 gestational-age-matched cases of spontaneous abortion or preterm delivery during the same period were also included as the control group. Diagnoses were based on the consensus statement of 2016 Amsterdam Placental Workshop Group. Statistical differences were analyzed by individual diagnostic terms.Results:The maternal age in rivanol group was (30.5±4.1) (range 22-41) years, compared with (30.9±4.3) (range 22-44) years in the control group. Gestational age was (23.2±3.5) (range 17-35) weeks and (23.3±2.8) (range 17-33) weeks in the rivanol and control groups. The incidence of chorioamnionitis in rivanol group was 91.8%, significantly higher than the control (63.0%, P<0.05); and there were more stage 1 (subchorionic) maternal response in rivanol than in the control (61.0% vs.28.6%, P<0.05) groups. In addition, acute deciduitis was also more common in rivanol group (27.1% vs. 13.6%, P<0.05). No significant difference was observed in fetal inflammatory responses (vasculitis of vessels in chorion plate and umbilical cord); maternal malperfusion (narrowing of intervillous space, increased intervillous fibrin deposition, decidual arteriopathy, villous infarction and retroplacental hematoma); and fetal malperfusion (villous stromal hemorrhage and avascular villi). Conclusions:The chemical chorioamnionitis caused by rivanol is characterized by maternal inflammatory response of low stage and high grade. The use of rivanol has no obvious impact on the fetal inflammatory response, maternal malperfusion and fetal malperfusion. Such morphologic changes may reflect the original placental lesions.
