ObjectiveTo investigate the diagnosis and treatment of pancreatic cystic neoplasm. MethodsThe clinical data of 40 cases of pancreatic cystic neoplasm from October 2001 to October 2013 in our hospital were retrospec-tively analyzed. ResultsPatients with pancreatic cystic neoplasm had no specific clinical feature. Ultrasonography and computed tomography displayed a cystic tumor in 57.5%(23/40) and 72.5%(29/40) of all patients, respectively, but could not distinguish the histological types. All of the patients had been operated, among them 2 cases were misdia-gnosed as pseudocysts and internal drainage; another 38 patients were undergoing the distal pancreatectomy. Pathologic examination results after operation showed 23 cases of serous cystadenoma, 9 cases of mucinous cystadenoma, 3 cases of intraductal papillary mucinous adenoma, and 5 cases of mutinous cystadenocarcinoma. Thirty five patients were followed-up. The followed-up time range from 2 months to 8 years, verage(74.2±12.8) months. Among the 3 patients with mucinous cystadenocarcinoma, 1 patient alived with no evidence of recurrence, the other 2 patients died of tumor invasion and metastasis in 4 months and 7months after operation. The others were still alive now with no evidence of recurrence. ConclusionSurgical resection is the most effective treatment for pancreatic cystic tumor, even if the patients with no any symptoms.
Objective To summarize ultrasonography, CT and (or) MRI imaging features of cystic liver lesions so as to improve its diagnostic accuracy. Methods The literatures relevant imaging studies of different types of cystic liver lesions at home and abroad were searched. Then with the etiology as clue, the imaging fetures of ultrasonography, CT and (or) MRI plain scan and enhancement scan were summarized. Results The cystic liver lesions had many types, their imaging findings were different and existed overlaps. The diagnosis and differential diagnosis of atypical cases were difficult. ① For the simple hepatic cyst, it was a round cystic mass with water-like echo, density and signal. The boundary was clear, and there was no separation in the cyst, without contrast enhancement. The sensitivity and specificity of diagnosing were higher by ultrasonography and MRI as compared with CT. ② For the bile duct hamartoma and Caroli diease, they were manifested as multiple cysts, widely distributed in the whole liver, without enhancement for the most lesions. The multiple cystic lesions without communicating with the bile duct was the key sign of differential diagnosis for these two dieases. ③ Enhancing mural nodules were more common in cystadenocarcinoma than cystadenoma. The accurate diagnosis of biliary cystadenoma depended on combination of ultrasonography, CT, and MRI findings. ④ For the cystic liver metastatic tumor, it was multiple cystic neoplasms in the liver parenchyma or around the liver. CT was the main method for the diagnosis, and which showed that the density was lower than that of the liver parenchyma, peripheral ring-enhanced lesion as enhanced scan. It was easy to distinguish with simple hepatic cyst by MRI. ⑤ For the cystic hepatocellular carcinoma, it presented as a multilocular cystic solid tumor. The presence of tumor thrombus in portal vein could help to the diagnosis. ⑥ For the undifferentiated embryonal sarcoma, CT plain scan showed the cystic low density mass with clear boundary, the edge with calcification, enhanced scan showed that the soft tissue composition presented continuous strengthening sign. There was no specific signal in MRI plain scan, and the periphery of the tumor was slowly strengthening. ⑦ For the liver abscess, it was easy to diagnose because it had different characteristic features in different pathological phase, but it was misdiagnosis of intrahepatic cholangiocarcinoma when its symptoms were atypical. ⑧ The ultrasonography and the CT were the optimal methods for the hepatic cystic echinococcosis and the hepatic alveolar echinococcosis respectively. The significances of imaging were to determine the activity of hydatid cyst and to identify anatomy structure among alveolar echinococcosis, bile duct and blood vessel, and judge invasion or not, MRCP was important for diagnosis. Conclusions Abdominal ultrasonography could be used as the first choice for diagnosis of cystic liver lesions, CT and MRI could be used as effective supplementary methods for it. A combination of various imaging techniques is key to diagnosis. Moreover, number and morphology of lesion, and solid component or not are important imaging features of diagnosis and differential diagnosis of cystic liver lesion.

ObjectivesTo systematically review the efficacy and safety of ciprofloxacin for non-cystic fibrosis bronchiectasis.MethodsDatabases including PubMed, EMbase, The Cochrane Library, CBM, VIP, CNKI and WanFang Data were electronically searched from inception to August 2018 to collect randomized controlled trials (RCTs) on ciprofloxacin in the treatment of non-cystic fibrosis bronchiectasis. Two reviewers independently screened literature, extracted data, and assessed risk of bias of included studies. Then, meta-analysis was performed by using RevMan 5.3 software.ResultsA total of 9 RCTs involving 1 666 patients were included. The results of meta-analysis showed that: compared with control group, the ciprofloxacin more efficiently eradicate bacteria from sputum (RR=4.34, 95%CI 2.04 to 9.23, P=0.000 1), decrease risk of the exacerbations (RR=0.81, 95%CI 0.71 to 0.93, P=0.002) and the mean bacterial load (MD=–4.08, 95%CI –6.29 to –1.87, P=0.001). However, there were no significant differences between two groups in clinical efficiency and adverse events.ConclusionsThe current evidence shows that, ciprofloxacin can decrease the mean bacterial load and risk of the exacerbation, and more efficiently eradicate bacteria from sputum in non-cystic fibrosis bronchiectasis patients. Due to limited quality and quantity of the included studies, more studies are required to verify the conclusions.

Each disease had its own lesions location and features of CT images. Conclusion CT is very effective on the localized and qualitative diagnosis of the giant cystic lesions in abdomen of infants.
From September 1988 to May 1985, 67 cases of thyroid cysts were treated with aspiration and ethanol injection. Patients were followed up clinically and ultrasonically 6 month to 4 years after treatment. Cure was defined as complete disappealance of the cyst or presence of a residual fibrotic mass less than 1 cm in diameter, effectiveness was defined as the residual mass less than 50% of the original one. After one to three injections, 27 out of 36 patients of thyroid adnoma with cystic change (75 %)were cured, the effective rate was 88.2%. The cure rate of nodular goiter with cystic change was 50%(14 out of 28 cases, while the effective rate was 82%.No serious complication occurred in this series. During the period of following up, no malignant change was found. The results suggest that aspiration of thyroid cyst with ethanol injection is a simple, well tolerated and low cost technique.

Fibropolycystic liver diseases (FLDs) is a rare genetic disorder, including bile duct hamartomas, congenital hepatic fibrosis, polycystic liver disease, Caroli’s disease, and choledochal cysts. Fibropolycystic liver diseases has received little clinical attention and exhibits a variety of imaging manifestations, leading to a high likelihood of missed diagnosis and misdiagnosis. Through this case, we delineate the characteristic imaging manifestations of the disease and its underlying pathological mechanisms. Our objective is to enhance readers' comprehension of the disease and thereby reduce the rate of missed diagnosis and misdiagnosis of the disease.
目的 评价不同外科手术治疗肝脏囊性占位的临床疗效以及不同外科治疗策略的优缺点。 方法 对1998年1月－2011年12月收治的肝囊性占位患者的临床资料进行回顾性分析。共纳入148例患者，其中单纯性肝囊肿患者86例（单发35例，多发51例），多囊肝病患者62例。43.9%（65/148）患者行腹腔镜囊肿开窗治疗，27.0%（40/148）患者行开腹囊肿开窗术，21.6%（32/148）的患者行经皮囊肿穿刺及硬化剂注入术，另有7.4%（11/148）患者行开腹肝部分切除联合囊肿开窗术。 结果 经过手术治疗后，患者症状缓解率高达100.0%；术中患者出血量以经皮囊肿穿刺及硬化剂注入术最少，而以开腹肝部分切除联合囊肿开窗术最多。对于单纯性肝囊肿单发患者，不同手术治疗后均未出现症状复发；对于单纯性肝囊肿多发患者，肝部分切除联合囊肿开窗术治疗未出现症状复发，而经皮囊肿穿刺及硬化剂注入、腹腔镜囊肿开窗和开腹囊肿开窗治疗则分别有3、4、2例患者发生症状或影像学复发，总复发率为17.6%(9/51)；对于多囊肝病患者，经皮囊肿穿刺及硬化剂注入、腹腔镜囊肿开窗、开腹开窗和肝部分切除联合囊肿开窗治疗则分别有2、7、3和2例患者发生症状或影像学复发，总复发率为22.6%（14/62）。 结论 目前常用治疗方式对于单纯性肝囊肿单发患者疗效均理想，但对于单纯性多发肝囊肿和多囊肝病患者远期效果均尚不理想。
