ObjectiveTo explore the clinical significance of lymph node metastasis in gastrointestinal stromal tumor (GIST).Methods A literature search to identify studies relating to GIST cases reported between January 1998 and December 2010 was conducted.The associations between lymph node metastasis and GIST clinicopathological features, gene expression, GIST stage, and GIST prognosis were evaluated.Results 6063 literatures were screened and only 16 GIST patients (median age of 49.25 years,10females) with lymph node metastasis were enrolled in this study.Among them,12 tumors were located in the stomach, 3 in the small intestine, and 1 in the esophagus.Morphologically, 13 specimens were mainly characterized by spindle cells.Gene analysis was examined in 7 cases.Conclusions Lymph node metastasis in GIST might more frequently found in the stomach, tumor stage of high grade, and cellular morphology of spindle-shaped.Gene mutation may have a relationship with lymph node metastasis.However, its clinical significance remains unclear.

ObjectivesTo compare clinical outcomes and safety of 5-Fu or capecitabine combined with oxaliplatin therapy for metastatic colorectal cancer. MethodsLiterature search were performed by key words,such as metastatic colorectal cancer,capecitabine,oxaliplatin,5-Fu on all randomized controlled trails reported on 5-Fu or capecitabine combined with oxaliplatin therapy for metastatic colorectal cancer before Jun.2011.Two authors drew the details of trail design,characteristics of patients,outcomes and so on from the studies included. Data analysis was performed by RevMan 4.2. ResultsAccording to the same screening criteria,6 clinical studies were included in this Meta-analysis. Sample volume in this Meta-analysis was 2189 colorectal cancer cases.The baseline characteristics of 5-Fu group were similar to those of capecitabine group.The short-term outcome such as response rate,RR was 0.92 [95 ％CI(0.82,1.02),P=0.12], and the long-term outcome such as median overall survival, median progression-free survival and the WMD was -0.19 [95 ％CI(-0.73,0.35),P=0.49],-1.91 [95 ％CI(-2.53,0.16),P=0.08],respectively,two groups weresimilar. In the comparison of Ⅲ-Ⅳ grade toxicity between the two groups, the incidences of neutropenic in 5-Fu group were higher than those in capecitabine group,and the RR was 0.24 [95 ％CI(0.11,0.55), P=0.0007]. However, the incidence of wand-foot symptoms in 5-Fu group was lower than those in capecitabine group, the RR was 2.83 [95％CI (1.66,4.82), P=0.0001]. ConclusionBoth 5-Fu and capecitabine were similarly effective in the therapy of metastatic colorectal cancer. And the Ⅲ-Ⅳ grade toxicity such as neutropenic was easier to happen in 5-Fu group,while the incidence of hand-foot symptoms was on the other hand.

OBJECTIVETo observe the clinical effect of Shen-reinforcing and menstrual cycle-regulating therapy (SRMCRT) combined with Western medicine (WM) in treating decline in ovarian reserve (DOR).

METHODSTotally 78 patients with DOR were assigned to the traditional Chinese medicine combined WM group (abbreviated as IM group, 40 cases), and the WM group (38 cases) according to random digit table method. Patients in the WM group were treated with hormone replacement therapy, while those in the IM group additionally received SRMCRT. The therapeutic course for all was 3 consecutive months. The therapeutic efficacy was compared between the two groups. The serum levels of follicle stimulating hormone (FSH), FSH/luteinizing hormone (LH), and estradiol (E2), as well as the development of sinus follicles were compared between before and after treatment in the two groups.

RESULTSThe therapeutic effective rate was 92.5% in the IM group, higher than that of the WM group (73.68%, P < 0.05). The serum levels of FSH, FSH/LH, and E2 decreased (P < 0.05) and the number of the sinus follicle increased (P < 0.05) in the two groups after treatment. Besides, IM was superior in decreasing serum levels of FSH and FSH/LH, and increasing the number of the sinus follicle (P < 0.05).

CONCLUSIONSSRMCRT was an effective method for treating ROD. IM was superior in decreasing serum levels of FSH and FSH/LH, and increasing the number of the sinus follicle.
