Background and purpose:The extent of lymph node dissection for the stageⅢ lower rectal cancer is still a subject of debate. Some Japanese researchers recommend improved lateral lymph node dissection for stageⅢ lower rectal cancers while American scholars claim that total mesorectal excision is sufficient. This study aimed to explore the clinical significance of improved lateral lymph node dissection for stageⅢ lower rectal cancer in patients treated with radical resection.Methods:Sixty-six patients with stageⅢ lower rectal cancer were enrolled. Among these patients, 31 had been treated with radical resection combined with improved lateral lymph node dissection, whereas the others received radical resection without improved lateral lymph node dissection.Results:In the group of improved lateral lymph node dissection, five patients had positive lateral node including four poorly differentiated adenocarcinoma and one mucinous cell carcinoma. Compared with the group without improved lateral lymph node dissection, the group of improved lateral lymph node dissection showed significant difference in sexual disturbance, dysuresia and operation duration (P<0.05), but not in the presence of anastomotic fistula and blood loss during operation (P>0.05). Furthermore, patients had lower rate of pelvis recurrence and better 5-year rate of survival for the group of improved lateral lymph node dissection (P<0.05).Conclusion:Radical resection with improved lateral lymph node dissection may decrease the pelvis recurrence rate and increase survival rate in patients with stageⅢ lower rectal carcinoma.

Objective To investigate the clinical efficacy and safety between laparoscopic and transabdomi -nal hysterectomy ,reduce the occurrence of complications measures .Methods On 154 cases of hysterectomy indica-tions were nonrandomly divided into two groups ,one group for the observation group of 79 cases of laparoscopic opera-tion,another group was control group of 75 patients with transabdominal operation;two groups had no significant differ-ence in age and disease .The clinical effect ,postoperative complications and safety between the two groups during and after operations were observed .Results The operation time of the laparoscopic group (72.0 ±13.2) min was signifi-cantly shorter than that of the control group (98.0 ±20.7)min (t=3.396,P=0.021);The bleeding quantity of the laparoscopic group(96.0 ±75.4)mL was significantly shorter than that of the control group (159.4 ±98.0)mL(t=9.680,P=0.014);The aerofluxus time of the laparoscopic group (17.2 ±4.2) h was significantly shorter than that of the control group(28.6 ±6.1)h(t=9.760,P=0.013).The average postoperative hospital stay time was significantly shorter in laparoscopic group(5.2 ±1.9)d than those in abdominal group(9.5 ±3.2)d (t=-5.025,P=0.018). The analgesic used in the laparoscopic group (3/89)was significantly shorter than that in the control group (48/78) (t=-8.820,P=0.000).Conclusion Laparoscopic hysterectomy is safe and effective .It is worth to promote in clinical,while improving the operation skills is the key to reduce the complications .

As a distinct clinicopathological entity, mediastinal gray zone lymphoma cannot be classified by using differential diagnostic criteria. The cases represent a spectrum of tumors having characteristics of both primary mediastinal large B-cell lymphoma (PMBL) and classic Hodgkin lymphoma (cHL). In the 2008 WHO Classification, a novel category designated B-cell lymphoma, unclassifiable, with features intermediate between diffuse large B-cell lymphoma and classical Hodgkin lymphoma (BCLu) has been created to include these neoplasms. The main features of BCLu are clearly different from those of conventional mediastinal large B-cell lymphomas. Diagnosis of BCLu requires a multiparameter approach incorporating morphological, immunophenotypic, immunohistochemical and other features. These lymphomas generally have a more aggressive clinical course and poorer outcome. There is no consensus on the optimum treatment, while the recommended therapies for aggressive B-cell lymphomas might be effective options.
