Objective To compare the safety and the long-term outcomes of laparoscopic and open radical resection for rectal cancer. Methods The clinical data of 602 patients who received radical resection at the Second Affiliated Hospital of Fujian Medical University from January 2000 to December 2008 were retrospectively analyzed.All patients were divided into the laparoscope group (324 patients) and the open group (278 patients).The numbers of dissected lymph nodes,lengths of proximal and distal resection margins,local recurrence rate,distal metastasis rate,overall survival rates and disease-free survival rates of the 2 groups were compared.All data were analyzed by the independent t test,chi-square test or Fisher exact probability. The survival rates were calculated by the life table method and were analyzed by the Wilcoxon (Gehan) test.Results The number of lymph nodes dissected in the laparoscope group and the open group were 21 ± 8 and 21 ± 9,with no significant difference between the 2 groups (t =1.120,P ＞0.05).The lengths of proximal resection margin were ( 15.1 ±1.3 )cm in the laparoscope group and (15.0 ±0.8)cm in the open group,with no significant difference between the2groups (t =1.452,P ＞0.05).The lengths of distal resection margin were (4.0 ± 1.6)cm in the laparoscope group and (3.3 ± 1.4) cm in the open group,with a significant difference between the 2 groups ( t =5.587,P ＜ 0.05 ).The overall local recurrence rate was 5.6％ (34/602),and no tumor recurrence was detected in the incision and port-site.The local reccurence rates were 6.2％ (20/324) in the laparoscope group and 5.0％(14/278) in the open group,with no significant difference between the 2 groups (x2 =0.363,P ＞ 0.05 ).The overall distal metastasis rate was 11.5％ (69/602),and the distal metastasis rates were 11.1％ (36/324) in the laparoscope group and 11.9％ (33/278) in the open group,with no significant difference between the 2 groups (x2 =0.085,P ＞0.05).The 3- and 5-year survival rates were 87.8％ and 83.0％ in the laparoscope group,and 84.9％ and 79.3％ in the open group,with no significant difference between the 2 groups (P ＞0.05).The 3- and 5-year tumor-free survival rates were 79.4％ and 69.2％ in the laparoscope group,and 79.7％ and 73.1％ in the open group,with no significant difference between the 2 groups ( P ＞ 0.05 ).The follow-up rate was 81.2％ (489/602).Forty-nine patients died,including 20 patients in the laparoscope group and 29 patients in the open group.Conclusion Laparoscopic radical resection for rectal cancer is reliable in the oncological efficacy,and is possible to achieve the similar long-term outcomes as that of open surgery.

With the common application of total mesorectal excision (TME) technique,the proportion of sphincterpreserving surgery for the mid-low rectal carcinoma is significantly increased.Anastomotic leakage after sphincter-preserving surgery is the most severe complication of rectal surgery,and it is the main reason which will lead to other complications and death.Many researches on the early diagnosis,prevention and treatment of anastomotic leakage are conducted by surgeons at home and abroad,and a further understanding of this complication is deeply realized.

Objective: This study explores the applicability of a multi-attribute decision-making method in assessing Guizhi Decoction (GZD) and its varieties as noted in the Shanghanlun. Methods: A known multi-attribute decision-making method, the analytic hierarchy process (AHP), was adopted to transform the clinical challenge of selecting optional decoction for a given combination of symptoms or signs into multiple criteria decision-making problem. Results: A normative model based on the AHP was realized for indications of GZD and its varieties. The indications of sub-family GZD-f (indications of GZD itself) were exterior illness; the indications of GZD-vf1 (indications of GZD's variants which consist of fine adjustments to the ingredients or content on the basis of GZD) were exterior illness with interior excess, suggesting that GZD-vf1 consisted of most conservative variants of GZD; the indications of both GZD-vf2 (indications of Guizhi Qu Shaoyao Decoction and its derivative variants) and GZD-vf3 (indications of Guizhi Gancao Decoction and its derivative variants) showed evolution from exterior illness to interior deficiency in 2 directions. As to efficacy evaluation of the decoction, GZD and its varieties (restricted to those comparable ones) were of equal efficacy on 3 popular signs or symptoms indicating exterior illness: floating pulse, aversion to wind and spontaneous sweating, which were the common ground of indications for the GZD family. Conclusion: Modeling of diagnostic procedure based on the AHP is proved practicable to analyze the clinical judgment system of traditional Chinese medicine. Quantification research on syndrome differentiation and decoction evaluation system focused on signs and symptoms is suggested as a feasible and reliable model.

By incorporation of tritiated thymidine or 5-bromodeoxyuridine and using them as the markers,we found that the basal cells,Clara cells and type II alveolar epithelial cells in the pulmonary tissues may in some way behave like stem cells and can eventually differentiate into respiratory tract epithelium.The slow progress of researches on pulmonary stem cells up to date has its root in the complex structure of pulmonary tissues and respiratory tracts,which is demonstrated by the facts that the respiratory system is composed of at least 40 types of cells,plus that the growth,renewal,and regeneration rate or capacity of respiratory epithelium are extremely limited.Mean while,there have been no specific stem cell markers for pulmonary and lung cancer,so researchers rely on stem cell markers borrowed from other systems to search for stem cells in pulmonary system.At present,the studies of lung stem cell markers were focused on Sca-1,ABCG2 /Bcrp1,cell retaining marker,surface marker,cell keratin and CCSP.Recently the lung stem cells have been shown to be the targets of transformation during lung carcinogenesis,which has provide more thoughts and direction for the occurrence and treatment of lung cancer.

OBJECTIVE:To study in vitro effects of tanshinoneⅡA to reverse multiple drug resistance. METHODS:MCF-7/ADM cells and A549/DDP cells were cultured with 0 [20 mg/L doxorubicin(ADM)or cisplatin(DDP),negative control],5 mg/ml tanshinone ⅡA(combined with 20 mg/L ADM or DDP)for 24 and 48 h. Then MTT method was used to determine cell viability, and polymerase chain reaction(PCR)was adopted to detect mRNA expressions of cell cycle control protein CDC25A and cell cy-clin dependent kinase (CKD2). RESULTS:Compared to the negative control,after MCF-7/ADM cells and A549/DDP cells were cultured with tanshinone ⅡA for 24 and 48 h,cell viability was weaker,also were mRNA expressions of CDC25A and CKD2. There were statistical differences(P<0.01). CONCLUSIONS:Tanshinone ⅡA combined with ADM or DDP can inhibit the viabili-ty of cell line MCF-7/ADM and cell line A549/DDP,decrease expression of CDC25A,CKD2 mRNA in cells and reverse multiple drug resistance in malignant tumors.
