Journal of Clinical Surgery 2000;0(06):-
Objective To study the relationship between the recurrence of stomach cancer and the procedure of primary operation.Method 1106 cases of gastric were analyzed cancer retrospectively.Results There are 853 cases in all patients we got the material of follow up. The outcome of distal radical resection is better than that of other resection according to the site of lesion. The most procedure is D2 resection according to the area of lymph node disection. The survival rate is higher in D1 resection than other resection.Conclusion Different procedures should be adopted in different site of lesion, area of lymph node metastasis and condition of tumor infiltration. Extraresection can be done only in selective patients.

Objective: TO establish methods for sensitive, rapid, economical detection of Th1/Th2 Cytokine gene expression. Method: sixpairs of Primers specific for the IL-2, IL-4, IL-10, IL-13, IFNr and B-actin were designed. A Sensitive and rapid method for detection of Th1/Th2cytokine genes by RT-RCR was established. Meanwhile another method: the RNA hybridization with sir cDNA probes were established. Results:The RT-PCR reaction and RNA hybridization was used to test five kinds of Cytokine mRNAs expressed 20 tumor cell lines on mRNAs were expressed in eleven Cell lines;The mRNAs in eight cell lines. Conclusion:The preliminary results suggested that RT-PCR and RNA hybridizationnight be used to test Th1/Th2 cytokine gene expression.

OBJECTIVE:To analyze the features and general patterns of adverse drug reactions (ADR) occurred in our hospital. METHODS: 209 ADR case reports collected in our hospital in 2007 were analyzed statistically in respect of patients' age and sex, route of administration, category of the drugs, organs and systems involved, and clinical manifestation of the ADRs. RESULTS: The ADR were more likely caused via intravenous dip (129 cases, 61.72%). Anti-infectives had the highest proportion to induce ADR(94 cases,44.98%), followed by nervous system drugs and cardiovascular system drugs. Quinolones were the leading anti-infective drugs causing ADR(35 cases, 37.23%), of which, Levofloxacin dominated the first place. The main presentation of the ADR was damage of skin and its appendages such as erythra and pruritus etc, followed by the lesions of digestive system and circulatory system. CONCLUSION: ADR monitoring awareness should be strengthened and the related ADR reporting system should be improved.

Objective To get more detailed information about the microsurgery of the Willis circle,in order to provide evidence of clinical operation.Methods The microsurgical anatomy of the Willis circle via combined frontotemporal-orbitozygomatic approach was studied in 5 adult cadaver brains under microsurgical scope. Results The Willis circle was composed of anterior communicating artery (ACOA), A 1 segments of the right and left anterior cerebral arteries (ACA), right and left internal carotid arteries(ICA) right and left, posterior communicating artery (PCOA), Pi segments of the right and left posterior cerebral arteries (PCA).The variation are present obviously in A 1 segment of the ACA. The outer diameter of left A 1 segment are larger than that of right ones. There are many perforating arteries of each part of Willis circle. Most of them arise from their original arteries, then course medial-superiorly to the optic tract, the pituitary stalk, the optic chiasm, the thalamus, hypothalamus, the floor of third ventricle, basal nuclei and internal capsule etc blood supplied areas. Conclusion To understand the microsurgical anotamy of the Willis circle and protections against its penetrating branches perfectly are the key to gain a good curative effect during the concerned operation .

The objective structured teaching evaluation (OSTE) is a new method for training and objective assessment of the teaching ability of clinical faculty by using standardized students and teaching scenario.It is mainly used to evaluate training programs,train teaching skills and assess teaching ability of clinical faculty.The differences and association between teaching ability,teaching skills and teaching scenario should be clarified before designing OSTE.Although there are some differences in various studies,OSTE can be summarized into two aspects:teaching administration knowledge and special teaching skills.Given the great potential of OSTE in training and assessing faculty,medical educators in general should actively explore its concept and application.

Objective To detect the expressions of CXCR4,Smoothened (Smo) and Patched (Ptch) in breast cancer,to analyze the clinical significance of the expression of CXCR4,and to evaluate the relationships among CXCR4,Smo and Ptch.Methods The expressions of CXCR4,Smo and Ptch from 121 cases of breast cancer specimens were detected by immunohistochemistry,and the results were analyzed.Results The positive expression rate of CXCR4 in breast cancer was 66.9%,which was positively associated with the lymph node metastasis (r =0.181,P =0.044).The positive expression rates of Smo and Ptch in breast cancer were respectively 58.9% and 64.5%.The expressions of Smo and Ptch were positively associated with the expression of CXCR4 in breast cancer (r =0.189,P =0.036 ; r =0.230,P =0.010).Conclusion The expression of CXCR4 in breast cancer is associated with the lymph node metastasis,and it is positiviely associated with the expressions of Smo and Ptch.Patients with breast cancer who express both CXCR4 and Hedgehog signaling pathway may have a higher risk of recurrence.

The incidence of locally recurrent rectal cancer is about 10%. Most patients have serious symptoms after tumor recurrence, which seriously affects the quality of life and prognosis of patients. Although it is more difficult to perform reoperation, it is still the main method to treat local recurrence of rectal cancer. At present, the main methods of reoperation include transabdominal anterior resection, combined pelvic organ resection, combined pelvic organ resection, and sacral resection. Open surgery is the main method. In recent years, with the extensive development of laparoscopic technology, laparoscopic techniques have been tried at home and abroad to perform reoperations for locally recurrent rectal cancer, showing good short-term results. The authors systematically introduce the application of laparoscopic technology in the reoperation of locally recurrent rectal cancer based on relevant research advances at home and abroad, in order to explore its clinical application prospects and promotion value.
