Combined operation and irradiation therapy has been performed on 22 patients with primary liver cancer in our hospital.All these patients were mal s.Age ranged from 15-49 years old with an average of 44.5. Histological dingnoais were. hepatocellular carcinoma in 21 cases and cholangiocarcinoma in 1 case. Seventeen (77.3%) patients were associated with liver cirrhosis, nineteen(86.4%)patients had positive AFP by counter- immunoelectrophoretic method.Clinically, 6 patients were stage I, 11 patients were stage II and 5 patients were stage III. The operative procedures consisted of liver resection in 17 patients (local resection 5, right hemihepatectomy 5, left lateral lobectomy 2, left hemihepatectomy 2, total right hepatectomy 2,and left medial lobectomy 1)and palliative operation in other 5 patients (hepatic artery ligation or embolization in 4 patients and hepatic artery infusion in 1 patient) .Radiotherapy comprised local or whole-liver irradiation with 60Co.Up to May 1983, 19 patients were followed-up, all of them survived more than 6 months.The 1, 2, 3, 4 year survival rates after treatment were 78.9%, 66.7%, 64.3% and 44.4% respectively with a median survival duration of 36 months.Data showed that the encouraging results of this method which were better than liver resection and radiotherapy or any other cmbined methods at present.

Objective To investigate the influence and clinical effect of assisted three-dimensional conformal radiation therapy (3D-CRT ) on obstructive jaundice caused by malignant tumors .Methods 90 cases with obstructive jaundice caused by malignant tumors of liver ,gallbladder and pancreases were randomly divided into observation group and control group ,45 cases in each group . Patients in control group were given comprehensive measures ,including tumors exairesis ,assisted chemotherapy and stereotactic ra-diotherapy ,and patients in observation group were given 3D-CRT based on tumors exairesis and assisted chemotherapy .Clinical effect ,serum bilirubin were observed 2 months after treatment ,adverse reactions were recorded during the treatment ,and survival rate in 2-year follow up in two groups were observed .Results Total effective rate in observation group and control group were 75 .56% and 57 .78% (P<0 .05) ,respectively ,and adverse reactions rate were 37 .78% and 57 .78% (P<0 .05) ,respectively .After treatment ,serum total bilirubin and direct bilirubin in two groups were all lower than those before treatment (P<0 .05) .Serum total bilirubin and direct bilirubin in observation group after treatment were (26 .3 ± 6 .5)μmol/L and(18 .9 ± 3 .3)μmol/L ,and were (39 .3 ± 9 .5)μmol/L and(26 .9 ± 6 .7)μmol/L in control group ,and there were statistical difference between two groups (P<0 .05) . Observation group′s survival rate was higher than that of control group (P<0 .05) .Conclusion It has good clinical effect of trea-ting obstructive jaundice caused by malignant tumors by 3D-CRT ,and it prolongs the survival time ,decreases serum bilirubin and improves jaundice symptom ,so it has some guiding significance to its treatment .

Objective: To assess the clinical application of transabdominal ultrasonography for the diagnosis of achalasia. Methods: The subjects were divided into 3 groups, with 8 patients suffered from achalasia as patient group, 10 normal individuals and 8 patients with cardiac carcinoma as controls. All subjects received water provocative test to study the lower esophagus and cardia. Sonographic findings were compared between the 3 groups. After treatment by administration of drugs, pneumatic balloon dilation, or intrasphincteric injection of botulinum toxin, the 8 patients were re-examined by TAUS for longitudinal comparison. Results: (1)The normal subjects had no dilation of cardia and lower esophagus before drinking water, but their cardias opened rapidly with the drinking action. (2)All the patients of achalasia were found to have dilation of lower esophagus before taking water. During 10 min continuous TAUS scanning, 5 of 8 demonstrated absence of relaxation of cardias and absence of water from the esophagus into the stomach. The other 3 showed slight and intermittent relaxation of cardias with water flow into the stomach. Thirty minutes after water provocative test, all the 8 patients had water retardation within the lower esophagus. (3)The patients of cardiac carcinoma had an ultrasound feature of cardiac ring enlargement and thickening of cardiac wall without dilation of lower esophagus before water provocative test. Water passed the cardia more slowly. Conclusion: TAUS is a readily accepted examination. It can quickly give reliable diagnostic clues to achalasia. TAUS can also be used for making assessment of therapeutic effect on achalasia.

Interleukin-15 is a multffunctional cytokine,which are the activating and induction factors of the T-cell,B-cell,NK-cell and lymphokine-activated killer cell (LAK).It can stimulate hematopoietic stem cell proliferation and differentiation,enhance immunity and has anti-tumor effects.IL-15 and IL-2 have similar structures and functions,but many activating effects of IL-15 are stronger than the other's.IL-15 is closely related to tumor development,and has broad application prospects in biological therapy of cancer.

Objective To compare strong and weak points of two different approaches of endoscopic thyroidectomy and to discuss the complication prevention of endoscopic thyroidectomy.Methods There were 10 cases of breast areola approach endoscopic thyroid surgery(Areola Group) and 11 cases of transcervical approach video-assisted thyroid surgery(Cervical Group).The operation time,intraoperative blood loss,length of hospital stay,and complications between the two groups were compared.Results The operations were completed successfully in all the 21 cases.The operation time was significantly longer in the Areola Group(132.4?39.1 min) than in the Cervical Group(89.2?16.8 min)(t=3.347,P=0.003).The intraoperative blood loss was significantly less in the Areola Group(12.9?4.3 ml) than in the Cervical Group(18.2?5.5 ml)(t=-2.442,P=0.025).The postoperative hospital stay was significantly longer in the Areola Group(4.2?1.0 d) than in the Cervical Group(3.0?0.6 d)(t=3.373,P=0.003).Follow-up observations for 6 months in the 21 cases showed no recurrence of thyroid tumor or occurrence of hypothyroidism.Conclusions Compared with video-assisted thyroidectomy through transcervical approach,breast areola approach endoscopic thyroid surgery has longer operation time,but more satisfactory exposure,fewer complications,and better cosmetic outcomes.

Objective Depending on the analysis of patients who were diagnosed as Community-Acquired Pneumonia in our hospital during 2004-2005, we compared with 《Directory for Diagnose of Community-Acquired Pneumonia》(Draft) in order to provide the guidance for the rational antimicrobial use in clinic. Methods Using the Retrospective Analyze method,we analyzed the cases which included: Name, Sex, Age, time during in hospital, Fees, Medicine and Note. Results Compared from 2005 with 2004, the top 3 ranks of the DDDs in 2004 were cefoperazone sodium/sulbactam sodium;L-ofloxacin ; etimicin and in 2005 were L-ofloxacin; cefoperazone sodium/sulbactam; etimicin. The rate of medicine fees were decreased,but the unites to use medicine,the average time in hospital and the average medicine fees were not deferent remarkable. Conclusions After 《Directory for Diagnose of Community-Acquired Pneumonia》(Draft) was carried out,the condition of application was more rational in 2005 than in 2004, but there were still many problems should be improved.
