ObjectiveTo evaluate the efficacy of XiaochengqiMixture (XM) on promoting healing of colonic stoma. MethodsForty Wistar rats were divided into two groups randomly after colonectomy: experimental group (n=20) and control group (n=20). In early postoperatively stage rats were given gastric administration of XM in the experimental group and pure water in the control group. On day 3, 7, and 14 after establishment of animal models, laparotomy was performed in two groups of rats, respectively. Anastomotic stoma and surrounding tissues were harvested to detect the context of hydroxyproline and collagen fiber proportion by Masson dying. ResultsOn day 3 after establishment of animal models, hyperplastic collagen with small fiber was observed while no fasciculus was found. Hydroxyproline context and collagen fiber proportion of rats were higher in experimental group than those in control group (Plt;0.05). On day 7 after operation, many fasciculuses were found in two groups of rats, hydroxyproline context and collagen fiber proportion of rats were higher in experimental group than those in control group (Plt;0.01). On day 14 after operation, fasciculuses became bigger and more regular in arrangement, but there was no significant difference between the two groups (Pgt;0.05). ConclusionXM is capable of promoting healing of colonic stoma and might prevent the occurrence of anastomotic fistula.
Objective To search evidence in the treatment of Philadelphia chromosome （Ph）-positive acute lymphocytic leukemia （ALL） for guiding chnical practice. Methods We searched MEDLINE （February, 1970～July, 2005 ） and SUMSEAILCH （till July, 2005 ）to identify systematic reviews（SIL）, randomized controlled trials（RCTs） and controlled clinical trials （CCTs） in the treatment of Ph-positive ALL. Results One RCT and 8 CCTs were identified. The results showed that Ph-positive ALL had a very poor prognosis . Chemotherapy and bone marrow transplantation （BMT） were the two main ways to treat the disease. Outcome of conventional chemotherapy treatment for adults with the disease was poor. Outcome of treatment with hyper-CVAD and imatinib mesylate was better and BMT was the only way which could potentially cure the disease. Conclusions Treatment of Ph-positive ALL with hyper-CVAD and imatinib mesylate may induce higher remission rate and disease free survival rate. BMT is the best way to cure the disease.
目的:比较三种检测幽门螺旋杆菌（Hp）的染色方法。方法:收集我科胃镜活检诊断为“慢性胃炎”和“胃溃疡”的蜡块42例,重新切片,分别做 HE常规染色,改良Giemsa 染色,免疫组化染色。在光镜下观察Hp的显示情况,其阳性率进行χ2检验。结果:三种染色方法的阳性率分别为HE染色:857%(36/42),改良Giemsa 染色:905%(38/42), 免疫组化: 929%(39/42)。χ2检验,免疫组化分别与其他两种染色方法比较,阳性率差异无显著性(Pgt;005)。但免疫组化Hp菌体与周围组织对比度最强,最易识别。结论:三种染色方法的阳性率无显著性差异，但采用免疫组化方法Hp菌体最易识别

Objective To study the expressions of phosphatese and tensin homolog deletedin chromosom ten （PTEN）, Fas/FasL system and matrix metalloproteinnases-2 （MMP-2） in human gastric cancer. Methods Seventy-five cases of gastric carcinoma were selected from paraffin wax embodied specimens with full clinicopathological data, and another 15 cases of normal gastric mucosa specimens were selected as the control group. SP immunohistochemistry was used to measure the expressions of PTEN， Fas/FasL and MMP-2 in them. The data was statistically analyzed by χ2 test and relative analysis. Results The expressions of PTEN, Fas/FasL and MMP-2 were correlated with the lymphatic metastasis, degree of infiltration, clinical TMN stage and pathological histological differentiated degree of gastric cancer (Plt;0.05). PTEN was positive correlated with Fas/FasL (r=0.401, Plt;0.001). MMP-2 was negative correlated with Fas/FasL (r=－0.720， Plt;0.001). MMP-2 was negative correlated with PTEN (r=－0.336， Plt;0.001). Conclusion There is guidance meaning in testing the expressions of PTEN, Fas/FasL and MMP-2 in gastric cancer to estimate the prevention, diagnoses, therapy and prognosis of gastric cancer.
【Abstract】ObjectiveTo study the current research status of minichromosome maintenance protein 2 (MCM2), the cell cycle proliferation marker, in the diagnosis of colorectal carcinoma. MethodsLiteratures about the application of MCM2 in the study of colorectal carcinoma were collected and reviewed.ResultsMCM2, as a marker of cell dysplasia and malignancy, was usually used in the study of carcinoma. The study on expression of MCM2 in the cell of colorectum in different proliferational stage might help to screen colorectal carcinoma as early as possible. ConclusionAs a relatively specific and sensitive marker of cell proliferation, MCM2 might become a promising mark for diagnosing colorectal carcinoma in the early stage.
ObjectiveTo study the expression and significance of proliferating cell nuclear antigen (PCNA) and argyrophilia nucleolar organizer regions (AgNORs) in colorectal carcinoma (CRC) and carcinoma adjacent mucosa (CAM).MethodsThe expression of PCNA in 48 cases of colorectal carcinoma tissue, CAM and 10 cases of normal mucosa was detected by immunohistochemistry techniques. AgNORs was determined with argyrophilia stain. ResultsThe PCNAlabeling index (PCNALI) and AgNORs count in CRC were higher than that in CAM and normal mucosa(P＜0.01).The PCNALI in Dukes C and D stage was higher than that in Dukes A(P＜0.05). The AgNORs count in 3 cmCAM was higher than 6 cmCAM (P＜0.01) and normal mucosa(P＜0.05). ConclusionSome cells proliferative activity were abnormal in CAM. It indicates that CAM is in an unstable premalignant state, which might have some correlation with the relapse of colorectal carcinoma.
Cytogenetic study of 18 colorectal carcinomas confirmed the extensive heterogeneity and the complexity of the karyotypic picture in this tumor.Karyotypic analysis showed that chromosomes 7 and 3 were of the highest chromosomal gaining frequencies(72%,66%) and chromosomal losses were shown in chromosome 17(50%),chromosome5(44%) and chromosome 18(33%).The structual rearrangements frequently involved were 17p(78%),5q(61%),6q,7q,8p,12q,2p,etc.A great number of marker chromosomes and polyploid chromosomes had bad prognosis relatively.According to these results,we conclude that chromosomes 17,5,and 18 may play an important role in the evolution of colorectal cancer.
Objective To assess the results of Fluoro Jade-c (FJC) staining in brain injury after deep hypothermia circulatory arrest (DHCA). Methods First, animal model of DHCA were established. We performed DHCA on six Chinese experimental minipigs and made sure all the pigs were alive after operation. Second, pathological examination was carried out on the brain tissues of these animals. After FJC staining, we respectively took out the positive and negative tissueparts and performed Hematoxylineosin (HE) staining, Nissl staining and Terminal deoxynucleotidyl Transferase BiotindUTP Nick End Labeling (TUNEL). Finally, the results of FJC was compared with TUNEL, Nissl staining, HE staining, to verify the accuracy and reliability of FJC in assessing brain injury after DHCA. Results Postoperative FJC staining discovered positive disease focuses on the experimental pigs. The comparative results of FJC were consistent with TUNEL (Kappa=0.526, Plt;0.01), Nissl staining (Kappa=0.555, Plt;0.01) and HE staining (Kappa=0.491, Plt;0.01). However, FJC staining image was much clearer and easier in identifying brain injury. Conclusion FJC is a reliable and convenient method to assess brain injury after DHCA.
