磁共振成像在多发性肌炎和皮肌炎治疗评价中的初探

目的 探讨多发性肌炎和皮肌炎治疗前后磁共振成像( MRI)检查的价值.方法 纳入15例多发性肌炎及皮肌炎患者,治疗前后分别行患者双下肢近端肌群MRI检查,检测血清肌酸激酶水平,并测定肌力;对比治疗前后肌力与MRI结果之间、肌力与肌酸激酶之间的相关性.统计学处理采用独立样本t检验及Pearson相关分析.结果 治疗前患者MR[计分2.37±0.62,肌酸激酶(3841±3175) U/L,肌力评分15.1±2.4;治疗后MRI计分1.30±0.28,肌酸激酶(549±338) U/L,肌力评分18.1±0.9,差异有统计学意义(P＜0.05).肌力与MRI计分、肌酸激酶水平均有相关性,且与前者呈强相关(r=-0.890,P＜0.05).结论 MRI能更好地反映多发性肌炎及皮肌炎患者肌力改善情况,较血清肌酸激酶有更高的敏感性.     

重组Ⅲ型人源化胶原蛋白阴道凝胶治疗阴道干涩临床研究

目的 探讨重组Ⅲ型人源化胶原蛋白阴道凝胶治疗阴道干涩的临床疗效和安全性。方法 将2014年1月至5月重庆医科大学附属第二医院和山西医科大学附属第一医院收治的80例阴道干涩患者随机分为两组,分别给予重组Ⅲ型人源化胶原蛋白阴道凝胶（研究组,2g/次）和透明质酸衍生物阴道凝胶（对照组,3g/次）治疗,隔日1次,共10次。比较治疗前后及两组之间阴道干燥指数、阴道p H值、外阴阴道刺痛、性交疼痛、症状缓解时间以及总体疗效。结果 符合研究方案且完成研究者,研究组38例,对照组38例。治疗后研究组干燥指数增加3分、增加了33.3%,有效率为63.2%;对照组增加2分、增加了27.3%、有效率为39.5%,两组间差异有统计学意义（P<0.05）。两组治疗对pH值均无影响。治疗后外阴阴道干涩刺痛、性交疼痛症状均有改善,两组间差异无统计学意义（P>0.05）。研究组对疗效满意度的主观评价中,满意及非常满意的比例为63.1%,对照组为24.7%,差异有统计学意义（P<0.05）。结论 重组Ⅲ型人源化胶原蛋白阴道凝胶可安全、有效地缓解阴道干涩症状,尤其适用于不宜使用激素治疗的患者。     

面神经F波研究

F波是周围神经在阈上超强刺激条件下，由逆行冲动引起的运动神经纤维的非突触性反应。F波最显著的特点是能够反映神经全程的功能状态。目前国内外各项神经F波相关研究在周围神经病中已逐渐成为常规检查手段，尤其对整个神经特别是近端神经的运动传导功能可做出早期估价。面神经是人体在骨管内走形最长的脑神经，应用F波可全程、早期的检测其功能状态。

??Objective    To explore the relationship between chronic periodontitis and cytokine interleukin-8 ??IL-8?? by literature review. Methods    The CNKI??Wanfang database??PubMed retrieval platform and Embase database were searched by computer. The research papers on the level of interleukin-8 in chronic periodontitis were collected. The retrieval time was up to 2016??screen literature according to the inclusion and exclusion criteria??use Stata12.0 software for meta analysis. Results    The level of IL-8 in gingival crevicular fluid in patients with chronic periodontitis was significantly higher than that in normal controls??P??0.05??. In the Asian population?? the level of IL-8 in gingival crevicular fluid in patients with chronic periodontitis was higher than that in normal controls??P??0.05??. In the western population??there was no difference in the level of IL-8 in gingival crevicular fluid between patients with chronic periodontitis and normal controls??P??0.05??. Conclusion    There is a significant difference in chemokines interleukin-8 between patients with chronic periodontitis and normal controls in the Asian population. Chemokines interleukin-8 may increase the risk of chronic periodontitis.

Abstract Objective To investigate the efficacy of laparoscopic hyperthermic intraperitoneal chemotherapy (HIPEC) combined intraperitoneal and systemic chemotherapy in gastric cancer patients with peritoneal metastasis. Methods A gastric cancer patient whose peritoneal cancer index was 39 during laparoscopic exploration was admitted at Peking University Cancer Hospital Gastrointestinal Center. The patient received laparoscopic HIPEC with docetaxel, followed by 6 courses of intraperitoneal and intravenous PTX??along with S-1 orally. Results CT scan showed distinct response during post-treatment evaluation. A second look by laparoscopy was suggested by MDT. No tumor cell was found in the lavage fluid through abdominocentesis and no metastasis can be seen by laparoscopic exploration. Then total gastrectomy plus D2 minus No.10 lymph node dissection was performed. The patient recovered smoothly after surgery. The pathology confirmed a ypT3N2M1, moderate to poor-differentiated adenocarcinoma, from gastric antrum to body. By September 2017, the patient was still in postoperative treatment. Conclusion Laparoscopic HIPEC combined with intraperitoneal and systemic chemotherapy showed effective interim results in gastric cancer peritoneal metastasis conversion therapy and is deserved for further researches.

??Value of preoperative lymphoscintigraphy in sentinel lymph node biopsy of breast cancer SUN Xiao*, LIU Juan-juan, WANG Yong-sheng, et al. *Breast Cancer Center, Shandong Cancer Hospital, Jinan 250117, China
Correcponding author: WANG Yong-sheng, E-mail: wangysh2008@yahoo.com.cn
Abstract Objectives Background Although preoperative lymphoscintigraphy for sentinel lymph nodes biopsy (SLNB) in breast cancer patients is undergone commonly, its clinical significance remains controversial. Methods Firstly, a database containing 716 consecutive breast cancer patients who received preoperative lymphoscintigraphy before SLNB was retrospectively analyzed. Secondly, 565 consecutive breast cancer patients were prospectively randomized into groups with or without preoperative lymphoscintigraphy before SLNB. Results In the retrospective study, sentinel lymph nodes (SLNs) were well imaged by lymphoscintigraphy in 86.6% patients, and negative lymphoscintigraphy results were associated with axillary node metastases. Failure of identification of SLNs by isotope alone was associated with whether axillary hot spot was imaged by lymphoscintigram (P<0.001). There were no significant differences in the false negative rate (P=0.731) of SLNB by isotope alone, in the identification rate (P=0.174) and the false negative rate (P=0.947) of SLNB by combination of dye and isotope between patients who had axillary hot spot in lymphoscintigram and those who had not. In the prospective study, 290 patients were randomized into the group with preoperative lymphoscintigraphy (82.1% patients were well imaged by lymphoscintigraphy) and 275 patients without. There were no significant differences between two groups in the identification rate (P=0.757) and the false negative rate (P=1.00) of SLNB by isotope alone, also in the identification rate (P=1.00) and the false negative rate (P=1.00) of SLNB by combination of dye and isotope. Conclusion Preoperative lymphoscintigraphy could not improve the identification rate and reduce the false negative rate of SLNB in breast cancer patients, and it is not a prerequisite for SLNB.

Abstract Objective To investigate the ultrasound characteristics of thyroid microcarcinoma. Methods The ultrasound imaging of thirty-four cases of thyroid microcarcinoma confirmed by surgery and pathology between January 2003 and January 2009 at the First Affiliated Hospital of Sun Yat-sun University was analyzed retrospectively. Results Thirty-two (94.1%) cases were detected as hypo-echo nodules. Twenty-eight (85.3%) cases were with irregular shape. Twenty-six (76.5%) cases were with irregular edges calcification. Blood flow was detected in 7 cases with CDFI and lymph node metastasis was found in 4 cases. Conclusion Hypo-echo nodules, regular shape, irregular edges and calcification are the ultrasound characteristic. Comprehending the characteristics may improve the pre-operation diagnosis efficacy.

Abstract Objective To investigate the surgical anatomical and histological data for the mesopancreas and mesopancreatic excision. Methods The anatomic structures of the peripancreatic space??the important vessels and the retroperitoneal structures of 5 cadaveric specimens between January and December 2016 in Basic Medicine Faculty of Shanghai Jiao Tong University were observed in the study. The structures of the vessels and retroperitoneum were histological studied. Results Posterior pancreatic space was an important anatomical plane of mesopancreatic excision. Celiac trunk and superior mesenteric artery were important anatomic landmarks of mesopancreatic excision. The No.16 lymph node was the extra anatomy structure of mesopancreas. There was a natural surgical space between the adventitia and sheath of the artery. There was a great deal of nerve and lymphatic vessel distribution on and outside the arterial sheath of the peripancreatic arteries. Conclusion Mesopancreas and mesopancreatic excision have the corresponding basis of surgical anatomy. Arterial sheaths dissection strategy for improving the dissection effect has certain anatomical basis.
