Objective To study the expression of p16 and Rb gene in primary gallbladder carcinoma (PGC). MethodsFiftysix cases of PGC and 26 of gallbladder benign lesions were observed by immunohistochemistry (SP). ResultsThe positive rates of p16 and Rb protein in PGC were 46.3% and 71.4% respectively. No association of Rb expression with histological grade, histological type, invasion, metastasis and prognosis was found. There were close correlation between p16 expression and invasion, metastasis as well as prognosis. The inverse correlation of p16 and Rb gene expression in PGC was confirmed. Conclusion The loss of p16 or Rb gene protein is an important molecular event in PGC,and closely related to the block in the negative regulatory pathway of all cell cycle. The detection of p16 protein may be useful in evaluating biological characteristics and prognosis in PGC.
ObjectiveTo determine the characters of symptomatic pancreatic pseudocyst due to acute pancreatitis and effects of surgical treatment with two kinds of procedure (internal drainage or external drainage). MethodsOne hundred and fifteen cases hospitalized during recent ten years were retrospectively analyzed.ResultsWe found that necrotic tissue existed in the pseudocyst in most cases and infection might occur in these pseudocyst. Although effect of two kinds of surgery was similar, the clinical course was different. The complications after surgery were fewer in patients underwent internal drainage than that with procedure of external drainage, and average hospital day was 7d in cases with internal drainage and 11d in cases with external one respectively. Surgery of internal drainage used in treatment was not only successful in noninfectious and single pseudocyst, but in infectious or multiple seudocyst.ConclusionInternal drainage should be used in most cases and considered as the first selection in surgery of pseudocyst due to acute pancreatitis.
Objective To investigate the treatment and therapeutic efficacy of intra-articular meniscal cysts by arthroscopy. Methods From January 2005 to December 2009, 9 cases of intra-articular meniscal cysts were treated by arthroscopy, including 5 males and 4 females, with an average age of 33.8 years (range, 24-46 years). Six patients suffered in left knees, 3 in right ones. Just 1 case had trauma history, the others had no obvious predisposing causes. The average course of the disease was 24.2 months (range, 4-36 months). The Lysholm score was (74.2 ± 11.6) points. Arthroscopy showed that the locations of cysts were the anterior horn of lateral meniscus in 8 cases and the anterior horn of medial meniscus in 1 case; all being single cyst (of them, 3 being multilocular cyst). Results All incisions healed primarily with no compl ications of infection and joint effusion. All 9 patients were followed up from 3 to 48 months with an average of 12.7 months. Preoperative symptoms disappeared or reduced and the range of motion of the knee returned to normal. TheLysholm score was (95.1 ± 3.4) points after 3 months of operation, showing significant difference (P lt; 0.01) when compared with the socre before operation. According to assessment standard described by Choy, the treatment outcome was excellent in 6 cases, good in 2 cases, and general in 1 case; the excellent and good rate was 88.9%. No recurrence was found during follow-up. Conclusion Arthroscopic surgery shows the advantages to maintain good function of knee for the treatment of meniscal cyst, it is the best choice for intra-articular meniscal cysts because of its mini-trauma, rapid recovery, thorough treatment and less recurrence. Simultaneously, partial or tatol meniscectomy or menicus repairing under arthroscopy is performed.
Thirteen cases of pancreatic cyst were analysed,including 6 cases of retention cyst,4 cases of cystadenoma and 3 cases of cystadenocarcinoma.The disease has no speciality in clinical symptoms ultrasonography and CT have high validity in locating the cyst,but no value in determing its pathological nature.Multiple compartment of the cyst were often seen.Serous fluid and flat epithelial cell existed mainly in retention cyst.Mucinous fluid and cubic/column epithelial cells were always seen in cystadenoma and cystadenocarcinoma.Cystectomy is an appropriate operation for the disease.
Objective To evaluate the therapeutic results of percutaneous injection of autogeous bone marrow for simple bone cyst and to analyze the prognostic factors of the treatment. Methods From March 2000 to June 2005, 31 patients with simple bone cysts were treated by percutaneous injection of autogeous bone marrow. Of 31 patients, there were 18 males and 13 females, aged 5 years and 7 months to 15 years. The locations were proximal humerus in 18 cases ,proximal femur in 7 cases and other sites in 6 cases. Two cases were treated with repeated injections. The operative process included percutaneous aspiration of fluid in the bone cysts and injection of autogenous bone marrow aspirated fromposterior superior iliac spine. The mean volume of marrow injected was 40 ml(30-70 ml).Results No complications were noted during treatment. Thirty patients were followed for an average of 2.2 years(1.5 years) with 2 cases out of follow-up. After one injection of bone marrow, 9 cysts(29.0%) were healed up completely, 7 cysts(226%)basically healed up,13 cysts (41.9%)healed up partially and 2 (6.5%) had no response.The satisfactory and effective rates were 67.7% and 93.5% respectively. There was significant difference between active stagegroup and resting stage group(P<0.05). There were no statistically significant difference in therapeutic results between groups of different ages, lesion sites or bone marrow hyperplasia(Pgt;0.05). Conclusion Percutaneous injection of autogeous bone marrow is a safe and effective method to treat simple bone cyst, but repeated injections is necessary for some patients. The therapeutic results are better in cysts at resting stage than those at active stage.
目的:探讨鼻前庭囊肿的最佳治疗方法。方法:在鼻内镜下辅以鼻窦电动切割器,对32例患者行鼻前庭囊肿揭盖术。结果:32例均获治愈,无1例并发症,随访1年以上,均未见囊肿复发和并发症。结论:鼻内镜下辅以鼻窦电动切割器行鼻前庭囊肿揭盖术,具有手术精确、时间短、创伤小、愈合快等微创手术优点,值得推广。
目的 探讨无功能性甲状旁腺囊肿(NFPTC)的诊断和治疗方法。方法 回顾性分析中国医科大学附属第一医院2008年3月至2012年10月期间手术治疗的6例NFPTC患者的临床资料。结果 6例患者中术前明确诊断3例;术后病理学检查证实均为甲状旁腺囊肿。术后无并发症发生;随诊7个月~5年,平均32个月,无复发。结论 NFPTC术前确诊困难,超声影像学特点对诊断有参考价值,手术切除是首选治疗方法。
