Therapeutic Evaluation on Advanced Pancreatic Cancer Treated by Integrative Chinese and Western Medicine──Clinical Analysis of 56 Cases 总被引:8,自引:0,他引:8
Objective: In comparison with chemotherapy, to evaluate therapeutic effects on advanced pancreatic cancer treated by integrative Chinese and western medicine (ICWM) therapies. Methods: Based on the retrospective study of 56 patients with advanced pancreatic cancer, life table was applied to the analysis of patients' survival rate and Xz test to the comparison of therapeutic response between ICWM and chemotherapy groups. Results: The results showed that 1-year survival rate in the ICWM group was 55. 37%±3.24%; 2-year survival rate 34. 61%±16. 31%; 3-year survival rate 25. 96%±24. 64%; 5-year survival rate 25. 96%±24.64%; and median survival period 16. 3 months. However 1-year survival rate in the chemotherapy group was 21. 95%±27. 54% ; 2-year survival rate 7. 31%±27. 54% ; 3-year survival rate 0 % ; and median survival period 7. 5 months. The therapeutic effects between two groups were significantly different (P=0. 004). Further analysis suggested that the reduction of cancer mass in the ICWM grou 相似文献

Summary
The compartment syndrome (cs) is characterized by an increased tissue pressure in a limited space. Pathophysiologically, it
is a multifactorial disease that is potentially induced by an initial trauma and develops according to the existence of cofactors.
Cofactors are, for instance, the circulation of the patient and the initial treatment of the impending cs. In particular,
the microcirculation is altered with endothelial destruction, development of a capillary leak, protein loss from intravasal
space and the development of an interstitial and intracellular third space. An impaired drainage of the lymphatic and venous
system causes a venous infarction. An arterial infarction results if the tissue pressure exceeds the arteriolar pressure.
An accompanying ischemia reperfusion mechanism increases the trauma load. In disadvantageous cases, the patients are in danger
of developing a multi-organ deficiency syndrome (MODS) by an uncontrolled inflammatory reaction, by intravasal volume loss
and by a myonephropathic systemic reaction. Clinically, the patients suffer a disproportionate amount of pain, followed by
neurological signs. Especially in noncompliant patients, tissue pressure measurement is useful. Resuscitation of the circulation
as well as splitting of casts is important. In case of a manifest cs, dermatofasciotomy has to be performed as an emergency
operation. Even if cs is diagnosed early and fasciotomy is carried out early, the development of sequellae cannot be avoided
in every single case.

Normal morphology of sacroiliac joints in children: magnetic resonance studies related to age and sex 总被引:2,自引:0,他引:2

Objective. To determine in a prospective study the normal MRI morphology of the sacroiliac joints (SIJs) in relation to age and sex
during adolescence. Design and patients. A total of 98 children (63 boys, mean age 12.7±2.8 years; 35 girls, mean age 13.7±2.3 years), ranging in age from 8 to 17
years, with juvenile chronic arthritis (JCA) but without signs of sacroiliitis fulfilled the study prerequisites (no back
pain and no pathologic changes of the SIJs on physical examination before MRI in a 1.5-year follow-up). An additional eight
HLA-B27-negative boys and eight HLA-B27-negative girls without arthritis served as controls. The MRI protocol comprised a
T1-weighted SE sequence, an opposed-phase T2*-weighted GE sequence, and a dynamic contrast-enhanced study in single-section
technique. Results. Noncontrast MRI permitted differentiation of “open” from ossified segmental and lateral apophyses of the sacral wings, with
a significant difference in age (P <0.05) between children with open and ossified apophyses. Ossification of the apophyses of the sacral wings was seen significantly
earlier (P <0.05) in girls than in boys. Girls also had a significantly higher incidence of transitional lumbosacral vertebrae, pelvic
asymmetries, and accessory joints. In the contrast-enhanced opposed-phase MRI study, normal cartilage of the SIJs showed no
contrast enhancement whereas the joint capsule showed a moderate enhancement. Conclusion. There are significant age- and sex-related differences in the normal MRI morphology of juvenile SIJs. Our findings might
serve as a standard of comparison for the evaluation of pathologic changes – in particular for the early identification of
juvenile sacroiliitis. 相似文献

The records of 28 patients who underwent free jejunal graft reconstruction after resection for cancer involving the pharynx were analysed. Seven patients had a T3 carcinoma, 15 patients T4 and six patients recurrence after laryngectomy. Ten patients had received radiotherapy in the past. Post-operatively, 15 patients (54%) had complications and two patients (7%) died. No significant difference was observed in the complication rate between the group that received radiotherapy in the past and those who did not. Nineteen patients received post-operative radiotherapy. Nine patients had no radiotherapy on the basis of complete resection or because of serious complications. For the whole group the 2-year recurrence free period and survival were 42% and 51% respectively. The postoperative radiotherapy group had a significantly better survival (73%) and recurrence free period (63%) than the group without post-operative radiotherapy (0%). Thus, post-operative radiotherapy seems indicated irrespective of resection margins. 相似文献

Abstract: The goal of psychotherapy is not only the dissolution of the symptoms, but also to attempt to bring about an improvement in adaptability and deepening the achievement of self-understanding. The nature of psychotherapy is based on the relationship between the therapist and patient. Such a goal and nature mean that some kinds of psychotherapy are beyond the medical model. In this paper ethical issues in psychotherapy are discussed as follows. 1) some complicated matters in informed-consent, 2) the hit or miss techniques of the poorly trained therapist, 3) the protection of privacy, 4) the sexual misconduct of therapists with patients, 5) special consideration for child-adolescent patients. 相似文献
