Objective To evaluate the surgical treatment for patients with malignant colorectal mesenchymoma, and to analyze the clinical data, pathological features and the common presenting symptoms and its immunohistochemical staining property. Methods The clinical data and the pathological findings, including immunohistochemical staining, of 17 patients with malignant colorectal mesenchymoma admitted from Jan 1990 to Mar 2005 were retrospectively analyeed. All the patients were followed up carefully. Results All the patients underwent operation, and all the tumors were proved malignant pathologically. In 6 cases left hemicolectomy was done, in 3 cases right hemicolectomy was done, in 2 cases the treatment was local resection from the rectum, and 6 patients received Mile's resection. The 1, 3 and 5-year overall survival rates for 17 patients with the total resection of tumor were 100%, 70.6% and 47.1%, respectively. The median survival time for 17 patients was 52 months. The final diagnosis of malignant GIST depended on the pathological examination, but the most worthwhile diagnostic criterion was the presence of CD117 and CD34 cells. Conclusion Since the prognosis is very poor, radical hemicolectomy is the principal treatment, and comprehensive treatment is necessary to improve clinical result.

Objective Through the qualitative study of surgical field free cancer cells of patients with breast cancer,to evaluate theprevention effects of intraoperative hot hypotonic solution soaking chemotherapy on cancer recurrence after resection of breast cancer.Methods 94 cases with breast cancer divided in to study group (n=48)and control group (n=46).Before the operation wound closed,both group surgical field washing solutions were collected for examination of free cancer cell,then the wounds of study group were treated with Hyperthermic soaking chemotherapy (41℃～42℃normal saline solutions 3000 ml+5-fluorouracil 1.0 g),once five minutes,total 3～4 times.While the wound of control group were soaked with normal saline solutions only.The soaking solutions were collected for examination of free cancer cell.The rates of free cancer cell in the surgical field and local recurrence rates in the both group were compared.Result The rates of washing solutions and the rates of soaking solution and the localy recurrent rates in the study group were 29.2%,8.3%,6.3%,which in the control group were 26.1%,19.6%,15.2%.Conclusions There are free cancer cells in the surgical field of breast cancer.Hyperthermic soaking chemotherapy can kill free cancer cell and reduce localy recurrent rate.

Objective To evaluate the clinical effect of chemotherapy via both hepatic artery and portal vein on liver metastasis of colorectal cancer. Methods Forty-eight patients with colorectal cancer (admitted to our hospital from Jan, 1994 to Dec, 2000)were divided into group Ⅰ, in which 17 patients received chemotherapy via both hepatic artery and portal vein, group Ⅱ in which 16 patients received simple hepatic artery chemotherapy, and group Ⅲ in which 15 patients received simple portal vein chemotherapy. Chemotherapy was begun 2 weeks after operation. The drugs used in chemotherapy regime were 5-fluorouracil(5-FU) 500mg/m 2 + Mitomycin(MMC) 4mg/m 2 + Epirubicin(EPI) 60mg/m 2, once per week, 2-3 times as a course. The chemotherapy regime was the same for the 3 groups. Results The respective effective rate for liver metastasis was 76.5%, 62.5%, 46.7% in group Ⅰ, group Ⅱ, and group Ⅲ. The 0.5, 1 and 2 year survival rates were 100%, 82.4% and 52.9% respectively in group Ⅰ, 87.5%, 62.5% and 43.7% respectively in group Ⅱ, and 93.3%, 60% and 33.3% respectively in group Ⅲ. There were statistically significant differences between group Ⅰ and groups Ⅱ and Ⅲ (P

Objective To explore the etiology,diagnosis and treatment of postsurgical gastroparesis syndrome(PGS)after radical gastrectomy for gastric carcinoma.Methods The data of 585 patients who had undergone radical gastrectomy for gastric carcinoma were retrospectively studied.The diagnosis was established with fiberoptic gastroscopy and biopsy before operation in all the patients,and radical subtotal gastrectomy was performed,with antero-colonic Billroth's Ⅱ anastomosis of the remnant stomach and jejunum.Results PGS occurred in 24 patients(age 46-81,mean 58.6 years)among 585 patients,the prevalence was 4.1%.In all the 24 patients,PGS occurred at the period when liquid diet was changed to semifluid diet,with the symptoms of epigastric fullness,nausea,vomiting and intractable hiccup.The vomitus contained large amount of gastric contents and a small amount of bile.The quantity of gastrointestinal decompression was 800-2000 ml/d.Upper gastrointestinal radiography using 38% meglucamine diatrizoate was performed in all the 24 patients,the contrast agent was taken orally or through gastric tube.It showed that the remnant stomach was atonic,gastric peristalsis was weak or absent,and evacuation of contrast agent was delayed.The anastomosis stoma was patent.Gastroscopy was performed in 18 patients,and a large amount of residual gastric content and anatomotic edema of anastomosis stoma were found.Howener,the gastroscope could be introenced into the duodenum or jejunal efferent loop through anastomotic stoma without difficulty,and no signs of mechanical obstruction were found.All the 18 patients were cured within10-38 days by conservative treatment.Conclusion The main causes of PGS may be the loss of gastrointestinal motility and anastomotic edema,while the risk factors may include old age,malnutrition,water-electrolyte imbalance,and peritoneal infection.Gastrointestinal radiography and gastroscopy are important diagnostic methods,and the patients can be cured by conservative treatment.

To evaluate the value of chemotherapy via portal vein pump implantation in preventing hepatic metastasis from colorectal cancer after a radical resestion. Patients after a radical resection were divided into two groups: the portal vein pump implantation chemotherapy group (Group A 32 cases), chemotherapy via peripheral vein(Grounp B 22 cases). The results showed that hepatic metastasis rate was 15 4% in group I and 36 4% in group 2. The survival rates of 1, 2, 3 years in group A were 98%, 83%, 61% respectively, while in group B they were 90%, 68%, 42%, respectively. The results suggested that portal vein pump chemotherapy was an effective treatment modality to prevent hepatic metastasis from colorectal cancer. Its clinical results were better than conventional chemotherapy via peripheral vein.

The peritoneal and hepatic recurrence and 3 year survival rate were compared between the 2 groups.Results The local and hepatic recurrence and 3 year survival rate in the treatment group were 21.9%,12.4% and 74.6%;those in the control group were 46.0%,27.4% and 46.8%,respectively ( P

Objective To analyze longitudinal layer‐specific strain in endocardial ,midcardial and epicardial layers of left ventricle (LV) by two‐dimensional speckle tracking imaging(2D‐STI) in patients with coronary heart disease (CHD) and to evaluate the regional or global systolic function of LV . Methods Seventy‐eight patients with suspected CHD were divided into CHD group (46 subjects) and control group (32 subjects) according to the results of selective coronary arteriography . According to the stenosis degree or number of coronary arteries ,the CHD group was divided into mild stenosis group ( corresponding blood‐supply vessel stenosis 50% -75% ) ,severe stenosis group ( corresponding blood‐supply vessel stenosis ≥75% ) or single‐vessel stenosis group ,multi‐vessel stenosis group . Two‐dimensional images with high frame rate were recorded in apical four‐chamber ,long‐axis ,two‐chamber of LV in all subjects . The strain parameters by EchoPAC analysis software included territorial longitudinal strain ( TLS ) of endocardial , midcardial and epicardial layers ( TLSendo ,TLSmid ,TLSepi) and global longitudinal strain ( GLS) of endocardial ,midcardial and epicardial layers ( GLSendo ,GLSmid ,GLSepi) . Results Regardless of with or without corresponding blood‐supply coronary artery stenosis and range of coronary artery stenosis , TLSendo ,TLSmid ,TLSepi and GLSendo ,GLSmid ,GLSepi all showed a gradient decrease( P < 0 .05) . Compared with the control group ,TLSendo ,TLSepi of mild stenosis group and severe stenosis group decreased significantly( P <0 .05) ,while there was no significant difference about TLSmid between the two groups( P > 0 .05) . Compared with the mild stenosis group ,TLSendo ,TLSepi of severe stenosis group decreased significantly( P < 0 .05) ,while there was no significant difference about TLSmid( P > 0 .05) . Moreover ,compared with the control group ,GLSendo ,GLSmid ,GLSepi of single‐vessel stenosis group and multi‐vessel stenosis group decreased significantly( P < 0 .05) . Compared with the single‐vessel stenosis group ,GLSendo ,GLSmid ,GLSepi of multi‐vessel stenosis group decreased significantly( P < 0 .05) . For predicting corresponding blood‐supply vessel stenosis ≥75% ,the sensitivity and specificity were 55 .6% , 72 .6% and 57 .8% ,76 .4% ,when the cut‐off of TLSendo and TLSepi were 20 .5% and 15 .5% respectively . For predicting multi‐vessel stenosis ,the sensitivity and specificity were 54 .5% ,71 .4% ;50 .0% ,87 .5% and 63 .6% ,87 .5% ;when the cut‐off of GLSendo , GLSmid , GLSepi were 21 .5% , 17 .5% and 16 .5%respectively . Conclusions Systolic dysfunction of LV happened through all layers in CHD patients . The longitudinal strain of layer‐specific by 2D‐STI can accurately evaluate the regional and global systolic function of LV in patients with CHD ,which can also be used to predict the degree or range of coronary artery stenosis .

Objective To explore the property of brain functional networks and cognitive function changes in patients with frontal lobe low-grade gliomas (LGG).Methods 8 cases of suspected frontal lobe LGG patients were undergone with resting-fMRI scanning to analyze the small-world property of the LGG,meanwhile the LGG groups had Montreal (MoCA) cognitive score exam compared with the control group.Results The value of MoCA was 22.5 ± 1.5,21.8 ± 2.0,and 27.9 ± 2.1 respectively with statistical significance (P ＜ 0.05) in the LGG groups and the control groups.The LGG group cognitive score was significantly lower than that in the control group with statistical significance (P＜ 0.05).As to threshold,the two groups were consistent with the small world property.The LGG local efficiency was smaller than that of the controls,the postoperative small world properties (σ=2.49) were lower than that the pre-operative (σ =2.68),the largest brain function areas of preoperative information transmission were respectively the supramarginal gyrus,posterior cingulate,insula,and the postoperative being the precuneus,calcarine sulcus and superior frontal gyrus.The maximum cluster coefficient of the preoperative functional network were respectively the entorhinal cortex,transverse temporal gyrus and the calcarine sulcus,and postoperative were Wilson,transverse temporal gyri and occipital gyrus.Preoperative information transmission path was less than the postoperative,and the small world properties were positively correlated with MoCA.Conclusion LGG accompany by the changes of cognitive function,and with the small world network property preand post-operation.
