Chinese Journal of Endocrinology and Metabolism 1986;0(04):-
Plasma concentrations of immunoreactivc beta-endorphin in patients with NIDDM were measured by radioimmuno-assay. It was found that the plasma beta-endorphin levels decreased in 68 cases of NIDDM especially in those with long duration of illness and chronic complication. These results suggested that beta-endorphin may be related to diabetes and its chronic complication.

BACKGROUND: Foreign scholars use thermotherapy, a new pathway for synthetic therapy of tumor, to perform hyperpyrexia combined with chemical drug radiotherapy of intraperitoneal infiltration and metastasis or to study on the therapeutic effect of metaphase and advanced stage tumor. Especially, establishing thermal biology and thermal dosiology is a scientific and quantified track for synthetic therapy of thermal radiotherapy, thermal chemotherapy and hyperthermal perfusion of tumor.OBJECTIVE: To analyze the thermal dose effect of regional radiofrequency (RF) hyperthemia combined with radiotherapy, chemotherapy and thermal perfusion on metaphase and advanced stage tumor.DESIGN: Controlled observation.SETTING: Key Department of Traditional Chinese and Western Medicine for Tumor, the 107 Hospital of Chinese PLA (General Center for Non-traumatic Treatment and Diagnosis of Tumor).PARTICIPANTS: Totally 1 455 patients with metaphase and advanced-stage tumor admitted to the General Center for Non-traumatic Treatment and Diagnosis of Tumor, the 107 Hospital of Chinese PLA between June and September 2006 who received conservative palliative treatment in the Department of Internal Medicine were recruited in this study. They were all confirmed by pathology and imageology. ECOG was scored 2 to 4 points. Informed consents of detection and treatment were obtained from all the involved patients. The study was approved by the Hospital Ethics Committee.According to the therapeutic regimen, the patients were assigned into thermal perfusion group (n =53), thermal radiotherapy group (n =874), thermal chemotherapy group (n =458) and simple hyperthemia group (n =70).METHODS: After admission, patients in each group were performed peritoneal and pelvic cavity perfusion,intensity-modulated radiation therapy, routine chemotherapy and integrated traditional and western medicine palliative therapy, respectively. Meanwhile, they received RF hyperthemia using in vitro endogenic magnetic field hyperthermia system. A thermocouple was placed in the abdominal cavity. Temperature at 3 different sites in the abdominal cavity was collected, and meanwhile two different sites for measuring temperature at rectum and external acoustic meatus were monitored. The maximal temperature (Tmax), minimal temperature (Tmin) and the average temperature (Tave) of therapeutic target were recorded. 40 ℃/min was used as thermal dose, thermal perfusion was performed once a week, and RF hyperthemia was conducted twice a week, 60 minutes once. Target temperature was 39.5 to 43 ℃, and the thermal dose of 40 ℃/min was calculated out. Intensity-modulated radiation therapy was conducted within 1 hour before heating at (3-5)Gy/time, 3 to 4 times a week. Total dose was DT 30 to 50Gy. Thermal perfusion was conducted 2 to 3 times a week, and intensity-modulated radiation therapy was conducted once to twice a week and 6 to 8 times a course of treatment. The thermal effect of each patient was analyzed at different temperature and different diseases.MAIN OUTCOME MEASURES: ① To analyze the effect of effective thermal dose. ② To evaluate the therapeutic effect and the improvement of quality of life according to World Health Organization (WHO) objective therapeutic effect evaluation criteria and Zubrod-ECOG-WHO scores. ③To observe the changes in abdominal dropsy.RESULTS: Altogether 1 455 patients with metaphase and advanced stage participated in the final analysis. ①After perfusion, body temperature was over 39.5 ℃ in most cases after 15-minute warming, over 40.0 ℃ after another 25-minute warming, over 41.0 ℃ after additional 35-minute arming, and even to 43.0 ℃ after frequent such a thermal therapy. Temperature over 41 ℃ was found in 91 cases, at 40 ℃-40.9 ℃ in 414 cases and at 39.5 ℃-39.9 ℃ in 950 cases. ② The thermal effect of 40 ℃/min could obviously improve the therapeutic effects of graded intensity-modulated radiation therapy, low-dose chemotherapy and thermal perfusion group. The total effective rate of thermal perfusion group, thermal radiotherapy group, thermal chemotherapy group and simple hyperthemia group was 81.6%, 81.9%, 80% and 50%, respectively. The clinical therapeutic effect of 40 ℃-40.9 ℃ and 39.5 ℃-39.9 ℃ in the thermal perfusion group, thermal radiotherapy group and thermal chemotherapy group was significantly better than that in the simple hyperthemia group (P < 0.05). ③ Comparison of Zubrod-ECOG-WHO score of patients before and after therapy: After therapy, Zubrod-ECOG-WHO score was enhanced in 76.3% patients. ④The changes in abdominal dropsy of patients before and after therapy: After therapy, abdominal dropsy changed in 75% patients.⑤The therapeutic effects of different diseases at different temperature: For the same disease, the therapeutic effects over 41 ℃ and at 40 ℃-40.9 ℃ were significantly different from those at 39.5 ℃-39.9 ℃(P < 0.05); However, the therapeutic effects over 41 ℃ were not significantly different from those at 40 ℃-40.9 ℃ (P > 0.05).CONCLUSION: ①The effects of regional RF hyperthemia combined with intensity-modulated radiation therapy are confirmed in the treatment of metaphase and advanced-stage of tumor. ② The therapeutic effects strengthen correspondingly with 40 ℃/min thermal dose increase or temperature increase.

Objective To evaluate the applicable value of two - dimensional speckle tracking imaging on assessing the local function and coronary collateral circulation of acute myocardial ischemia in dogs.Methods Open-chest model to induce acute myocardial ischemia in 10 dogs was established by ligating their anterior descending coronary artery(LAD). Two-dimensional dynamic gray- scale images of two standard left ventricular short axis views at the levels of mitral annulus and papillary muscle were acquired for the off -line comparative analysis before the operation and 0, 30, 60, 120, 240 and 360 minutes after the operation respectively. Peak systolic circumferential strain(CS), peak systolic radial strain(RS) and left ventricular fraction shortenting(LVFS) of 12 segments at the levels of mitral annulus and papillary muscle were analyzed with QLAB software. After the lab experiment,the fresh hearts of dogs were dyed by TTC.Results ①Compared with the preoperative value , the peak systolic CS and RS of ischemia myocardial regions(anteroseptum,anterior and lateral) in left ventricular short-axis decreased significantly( P <0. 05)during 30 to 60 minutes after ligating LAD. Sixty minutes later, the peak systolic CS and RS had a tendency to return to the level before the operation,although the statistical difference was existing. The peak systolic RS and CS also decreased in certain nonischemic regions (inferolateral and inferior). But CS and RS in inferoseptal regions didn't alter significantly. ②Compared with the preoperative value,LVFS in the ischemia regions were significantly decreased( P <0.05), while nonischemic regions had no significant difference. ③The results of TTC dyeing showed that the infarcted regions in left ventricular short-axis were anteroseptum, anterior and lateral with blood supplied by LAD, which were consistent with the results of RS and CS. Conclusions RS and CS,as the parameters of myocardial strain may reflect the range and extent of acute myocardial ischemia,and the strain changes of local myocardial segments after the construction of coronary collateral circulatory.

Studies have shown that women's menopause caused by permanent cessation of ovarian function is closely related to lipid metabolism disorders. Er-xian Decoction has been used in the clinical treatment for gynecological diseases and has a good effect on diseases related to reduced sex hormone function. In this study, metabolomics was performed on bilateral ovariectomized model rats within 12 weeks after modeling to mimic the physiological state of menopausal women in different menopausal stages and Er-xian Decoction dosed model rats. The results of liver oil red O staining sections showed lipid metabolic disorder of bilateral ovariectomized model rats and the regulating effects of Er-xian Decoction. 46 potential biomarkers (6 steroid hormones, 3 sphingolipids, 11 phospholipids and 26 glycerides) in plasma and 32 potential biomarkers (1 steroid hormones, 20 phospholipids and 11 glycerides) in liver were obtained based on lipidomics analysis. Then, we analyzed the differential metabolic pathways and construct the lipid metabolism network significantly regulated by Er-xian Decoction. The results provided valuable information for in-depth understanding of the gradual changes on lipid metabolism disorders under menopausal conditions and the characteristics and mechanisms of compound Er-xian Decoction's regulatory effects. The study complied with the procedures established by the Animal Experiment Ethics Committee of the Institute of Materia Medica, Chinese Academy of Medical Sciences and passed the animal experiment ethics examine (No. 00000918).
