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.
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。
Objective To investigate the cl inical outcome of treating dorsal wrist gangl ion with an improved surgical strategy by excising the gangl ion completely along their stalk and repairing the dorsal carpal l igaments under brachial anesthesia. Methods From March 2005 to January 2007, 34 patients with dorsal wrist gangl ion were treated and studied retrospectively. There were 14 males and 20 females, aged 25-65 years (43 years on average). The left sides were involved in 22 cases and right sides in 12 cases. Thirteen cases of relapse received excision for 1 to 4 times under local anesthesia, with amean period of 17 months (14 days to 7 years) from excision to recurrence. Twenty-one patients were first attack cases with a mean period of 11 months (15 days to 8 years) from diagnosis to excision. The size of the gangl ion ranged from 1.5 cm × 1.2 cm to 4.5 cm × 4.0 cm. Now, each surgical process was performed under brachial anesthesia, and a pneumathode tourniquet was used. In 6 patients, the stalks of gangl ion did not invade the carpal l igaments, and gangl ion was removed completely without immobil ization after operation. In 28 patients, the stalks of gangl ion invaded the carpal l igaments, gangl ion was excised completely along its stalk to the dorsal carpal structure; the l igaments were sutured directly in 16 cases and were repaired with adjacent tissue such as the wall of sheathing canal of extensor tendon in 12 cases. The wrists were immobil ised for 3 weeks. Results Primary wound heal ing was achieved in all incisions. All patients were followed up for 26-36 months with an average of 31.5 months. Only 2 cases (5.9%) recurred. The range of motion of the wrist remained normal and the symptom of the dorsal wrist was rel ieved sl ightly. Patients’ satisfaction score ranged from 60 to 100, with an average of 83.8. Conclusion The gangl ion should be excised completely together with defect repair of dorsal carpal l igament under brachial anesthesia and the wrist immobil ised for 3 weeks, the recurrence rate will be reduced greatly.
Objective To study the effect of microtraumatic treatment of postoperative recurrent bone cysts in juvenile patients. Methods FromDecember 1984 to December 2003, 36 cases of postoperative recurrent bone cysts after focal curettage and bone graft included 19 males and 17 females, aging 9-21 years-with an average of 15 years. The size of bone cyst ranged from 2.5 cm×6.0 cm to 3.5 cm×13.0 cm with an average of 3.0 cm×8.0 cm. The locations were proximal humerus in 18 cases, humeral shaft in 10 and femoral trochanteric region in 8. The focal curette and bonegraft were given once in 23 cases, twice in 10 cases and 3 times in 3 cases. The interval between recurrence and microtraumatic treatment was 5-13 months (6.5 months on average). The posteroanterior and lateral X-ray films were takento determine the location, range and feature of the focus. Under local anesthesia, 2 canulated needles were used; one was used to aspirate the contents of the cyst, the other was used to inject hydrocortisone acetate. The dose was determined according to the range of the focus. The treatment was repeated every 3.54 months until the focus healed. Results All patients were followed up from 3 to 18 years with an average of 5 years. The microtraumatic treatment was repeated 3-11 times with an average of 6 times. Twenty-six cases healed completely, 6 cases healed significantly, and 4 cases healed partially. No local or general complications occurred during the treatment. Conclusion This microtraumatic method for the treatment of postoperative recurrent bone cyst in juvenile patients has following advantages : less pain, easy manipulation, no hospitalization, low cost and definite effect.
