Objective To analyze the clinical and CT characteristics of pancreatic metastasis to improve the correct diagnosis rate.Methods The clinical and CT data of 14 patients with pancreatic metastasis were reviewed retrospectively.Results Among the 14 patients,the primary malignancy was lung cancer in 6 cases,renal carcinoma in 3 cases,colon carcinoma in 2 cases,laryngeal cancer in 1 case,gastric cancer in 1 case and ovarian carcinoma in 1 case.Pancreatic metastases from renal carcinomas often developed a long period after initial nephrectomy and survived for a relatively long time.Abdominal CT plain scan and enhanced scan was performed in all cases.Four cases were of solitary type,9 cases were of multiple types and 1 was of diffuse type.Totally 28 lesions were found,which were usually located in the neck and body of the pancreas,the diameter of 28 pancreatic lesions was ranging from 0.5 cm to 11 cm,with a mean diameter of 2.3 cm.On CT plain scan,there were 19 hypodense lesions,7 slightly hyperdense lesions and 2 isodense lesions,5 necrotic lesions.On enhanced CT,the lesions showed moderate enhancement in 7 cases,circular enhancement in 6 cases,moderate and circular enhancement in 6 lesions,obvious enhancement in 8 lesions and no enhancement in 1 lesion.All patients had extra-pancreatic metastases,and 2 cases had peripheral vascular invasion.Conclusions Pancreatic metastases are rare,often accompanied with multiple lesions and extra-pancreatic metastases.The CT features of pancreatic metastases from renal carcinomas are slightly hyperdense and obvious enhancement; in other metastases,there are hypodense,morderate and/or circular enhancement lesions.Accurate diagnosis can be achieved by knowledge of patients' medical history.

Objective To explore the clinical effect of endoscope emergency operation in the treatment of gastric variceal bleeding.Methods According to the digital table,90 patients with acute bleeding gastric varices were randomly divided into the control group and the observation group,each group 45 cases.The control group only received drug treatment,and the observation group was given endoscopic therapy.The clinical effect of the two groups were compared.Results The immediate hemostatic rate,rebleeding rate,varicose veins subsided total efficiency of the observation group were 100.00％,17.78％,86.67％,respectively,which were better than those of the control group (84.44％,44.44％,28.89％) (x2 ＝ 5.72,P ＜ 0.05).Conclusion Endoscope emergency operation combined with oral drug in treatment of gastric variceal bleeding has good effect,can achieve rapid hemostasis,prevent recurrence,and it is worthy of clinical application.

Objective To compare the clinical efficacy of different doses of ultrafine extracted granule preparation (EGP) and traditional herbal decoction (THD) of Li Zhong Tang in treatment of epigastric pain. Methods Sixty cases of epigastric pain patients in accordance with the diagnostic criteria of deficiency and cold pattern of spleen and stomach in TCM were randomly divided into THD group, 1/3 dose group and 1/5 dose group, and were given THD, 1/3 dose of ultrafine EGP and 1/5 dose of ultrafine EGP, respectively. The clinical efficacy of the three groups after one course of medication was comparatively analyzed. Results There were no significant differences in age, course of disease, symptom score before treatment, epigastric pain efficacy and syndrome curative effect among the three groups, the differences had no statistical significance (P>0.05). The severity, frequency and duration of epigastric pain were all reduced in the three groups, with significant differences between before and after treatment (P<0.05). Conclusion There are no significant differences in the clinical efficacy on epigastric pain among THD, 1/3 dose of ultrafine EGP and 1/5 dose of ultrafine EGP. In addition, the effect of 1/3 dose group is very close to the THD group.

BACKGROUND:Tissue-engineered biomaterials have the similar structure and function with autologous tissues. OBJECTIVE:To explore the osteoinduction of the bone biomaterial composited with rat bone marrow mesenchymal stem cel s in the treatment of large costal defects. METHODS:Forty Wistar rats were enrol ed used for the preparation of right large costal defect models, and then randomized into two groups, fol owed by the implantation of calcium chloride-sodium alginate gel (control group) or chloride-sodium alginate-bone marrow mesenchymal stem cel s (experimental group). At 2, 4 and 8 weeks after implantation, chest X-ray radiograph and histological examination of the defect region were conducted. RESULTS AND CONCLUSION:X-ray showed that in the experimental group, the defect area had no significant changes at the 2nd week after implantation until the formation of few bones at the 4th week;and at the 8th week, both ends of the defect region gradual y connected, and newly formed bones were ful of the defect. In contrast, the defect region in the control group showed no obvious bone healing, and both ends of the defect closed and osteosclerosis occurred. In the experimental group, there were a smal amount of fibrous tissues and numerous inflammatory cel s infiltratied in the material compartment, and no connection occured between the material and broken ends;there were numerous inflammatory cel s but no bone tissues in the control group at the 2nd week. At the 4th week, the scaffold degraded gradual y and abundant bone tissues were seen in the experimental group;the scaffold degraded little, and bone tissues aggregatied at the both defect ends in the control group. Up to the 8th week, the two kinds of scaffolds degraded mostly. A large number of bone tissues and trabeculae formed and the both defect ends were connected with the newly formed bones in the experimental groups, while in the control group, osteosclerosis appeared at both ends of the defect. To conclude, the bone biomaterial composited with rat bone marrow mesenchymal stem cel s promotes the repair of large costal defects.
