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.

Objective To investigate the feasibility,technique and clinical significance of preserving the great auricular nerve in parotid benign tumors surgery during the first postoperative year.Methods Fifty-two patients with parotid benign tumors were randomly divded into 2 groups.24 patients (group sacrificed) underwent classic parotidectomy with sacrifice of the great auricular nerve.The surgeons spare the nerve in the 32 patients with FOCUS ultrasonic harmonic scalpel (group preserved).Results After surgery,both groups showed lower levels of subjective sensation and sensory function test at auricle.These alterations were less pronounced in group preserved.Both groups showed improvement over time.In group preserved the sensory function reached normal level by 12 months after surgery.The recuperation in group sacrificed was partial at 12 months after operation.Conclusion The great auricular nerve preservation during parotidectomy is feasible,It can decrease sensory disturbance in the early postoperative period and avoid the permanent sequelae that occur when the nerve is sacrificed.The FOCUS ultrasonic harmonic scalpel technique can reduce the operation time.

Postoperative pancreatic fistula (POPF) is the most common complication after pancreaticoduodenectomy (PD) and remains a challenge to pancreatic surgeons.In pancreaticojejunostomy,the methods of reconstruction,experience and operational techniques of surgeons are closely related to POPF.Based on a literature review and on personal experience,the author presented the basic requirements and principle in reconstructing a safe pancreaticojejunostomy (PJ).The traditional methods of pancreaticojejunostomy and their recent developments were evaluated,with their advantages and disadvantages compared.The indications of various types of PJ and the special skills required were summarized.According to his own experience,the author described in detail his recommended method of anastomosis.

Objective To explore the ways to strengthen the mode and effect of the standard community management of the diabetes,and the management model of diabetic mellitus that adopt to current situation of China.Methods 80 diabetics patients were divided into intensive group and common group,and the period of the treatment is three consecutive months.We observed the levels of FBG,2hPG,HbA1c and the cost of drugs.Results The levels of FBG(6.82 ± 1.23),2hPG[(9.51 ± 2.18)mmol/L]and HbA1c(7.52 ± 1.31)％ in intensive group were significantly lower than common group[(8.65 ± 2.31)mmol/L、(12.22 ± 3.11)mtmol/L,(10.32 ± 3.51)％](t =3.12,3.25,3.56,3.69,all P ＜ 0.05).The cost of drugs in intensive group[(621.5 ± 204.5)yuan]was significantly lower than common group[(796.5 ± 240.6)yuan](t =3.69,P ＜ 0.05).Conclusion The ways to strengthen the mode could spend less but control disease well,and improving the existing community diabetes management should be truly effective in reducing medical costs.

Objective To investigate the changes and clinical significance of hemorrheology and platelet parameters examination in patients with hypertension. Methods Hemorrheology and platelet parameters were detected in 78 patients with hypertension and in 72 healthy subjects as control group. Then difference were compared. Results The hemorrheology and platelet parameters in he patients with hypertension at stage Ⅰ were no different in comparison with the control group(all P＞0.05) ,which at stage Ⅱ and Ⅲ were significantly different in comparison with stage Ⅰ and the control group ( all P ＜ 0. 05). and at stage Ⅲ were significantly different in comparison with stage Ⅱ(all P＜0.05). Conclusion The changes ofhemorheology and platelet parameters were closely related with hypertension,which were helpful to the clinical diagnosis of hypertension and had important significance to the therapy, monitor and prognosis of hypertension.

Differential treatment based on signs and symptoms is the special points of TCM,the identification of syndrome is the basis of differential treatment.Scientific research on syndrome plays a leading role in unifying pathogenesis of dyslipidemia,and certainly improves the research level of dyslipidemia in TCM.According to the status quo of lipid abnormality research,the research in this field can be conducted in two aspects in priority:firstly,the research of subjective symptoms can provide some basis for TCM research;secondly,the associativity of TCM syndromes and the metabolic syndromes is advantageous for exploring the nature and rules of lipid abnormality in TCM,it will be helpful for the improvement of lipid abnormality differentiation and treatment.
