We studied the immunoreactive Beta-endorphin (ir-?-Ep) plasma levels inresponse to an oral glucose tolerance test in 7 children with simple obesity and 7 childrenof normal weight. It was shown that the levels of ir-?-Ep and insulin were significantlyhigher in the obese children as compared to controls during oral glucose tolerance test,which reached a peak at 60 minutes. The result supports the concept of a possible linkbetween Beta-endorphin and glucose homeostasis.

OBJECTIVE: To investigate the effect of Wuling capsules on the activities of IL-2 and IL -6 in healthy mice and mice with immunological liver damage .METHODSBALB/C mice were treated with LPS(experimental group)or were not treated (control group) .12 days after giving Wuling capsule ig, the suspension of spleen cells of mice was cultured for 48h and 72h and the supernant fluid was collected for test.The IL - 2 was detected with MTT and IL - 6 with radio - immunoas-say. RESULTS: Wuling capsules could promote Th cells to secret IL- 2 and markedly elevate the liver - damage - induced low level of IL- 2.Wuling capsules did not effect the levels of IL-6 significantly in both healthy mice and mice with liver damage. CONCLUSION: Wuling capsules can promote the secretion of IL-2 and have immunoregulatory actions.

Aim To investigate the influence of Tanshinone ⅡA on cytokine secreted by kuppfer cells via LPS stimulation,and explore its mechanism of therapying chronic hepatic disease. Methods The liver cell and kupffer cells were isolated and the model of liver cell injuries was made induced by LPS and D-GlaN, and the effects of TanshinoneⅡA was observed on the injuries of liver cell induced by lipopoly-saccharide(LPS) and D-Galactosamine(D-GlaN). Cytokine were released secreted by kupffer cells through LPS stimulation and the contents of TNF-?,IL-6,IL-8 were determined by radio-immunoassay. The hepatocyte morphological character was observed by HE stain,the expressions of TNF-?、CD14、iNOS、eNOS in kupffer cell were explored by immunohistochemical, double-decker chamber was used for observing the damage of hepatocyte caused by cytokine secreted by kupffer via LPS stimulation. Results Tanshinone ⅡA could restore the injury of liver cell induced by D-GlaN and LPS, the levels of ALT、MAO、LDH-L、GSH-S and contents of MDA were significantly reduce.It could inhibit TNF-? IL-8 secreted by kupffer cells through LPS stimulation ,and the expressions of TNF-?、CD14 Inos、eNOS in kupffer cell through LPS stimulation were inhibited. Blocking injuries of the inflammatory cytokine release excessive on liver cell, it hadn′t the protect action on liver cell damage suffer from inflammatory cytokine.Conclusion The mechanism of Tanshinon ⅡA of blocking liver cell injuries induced by D-GlaN and LPS may be correlation with inhibiting the excessive cytokine by kupffer cells

OBJECTIVE:To investigate the effects of Bupleuri plus Saliva miltiorrhiza on preventing the formation of hepatic fibrosis in rats METHODS:To establish an animal model of hepatic fibrosis by feeding high fat diet and 10% alcohol and subcutaneously injecting CCl4 and to detect the zymogram and biochemical parameters and observe the pathological changes of liver tissue RESULTS:Bupleuri and Saliva miltiorrhiza could significantly depress the activities of ALT,AST,MAO,ALP and had no influence on the ?-GT in serum,the serum TG was decreased and TG in tissue was obviously raised and serum GSH was elevated in hepatic fibrosis rat The extract could significantly decreased the levels of PC Ⅰ and PC Ⅲ in hepatic fibrosis rat The histopathological examination showed that the extract could diminish liver degeneration and necrosis,and block the formation of fiber diazoma,the degree of collagen proliferation was significantly lower than that of the control group CONCLUSION:Bupleuri and Saliva miltiorrhea extract could effectively protect the liver cell,and could retard the formation of hepatic fibrosis as well

Objective To compare the dose distribution of reserved planned tangential beam IMRT(2-field IMRT) with multifields beams IMRT(6-field IMRT) of the bulk-recurrent chest wall in postmastectomy breast cancer patients.Methods For 8 patients with chest wall in postmastectomy breast cancer bulk-recurrence,2-field IMRT and 6-field IMRT plans were generated on PTV in Pinnacle Planning System.The prescribed dose of PTV was 50 Gy in 25 fractions and GTV was 66-70 Gy which irradiated incrementally by subsequent plan in 8-10 fractions.The conformal index (CI) and homogeneity index (HI) of 95％ of prescribed dose over PTV were compared,while the dose distribution on ipsilateral lung and heart were evaluated.Results The CI of PTV by 6-field IMRT (0.66 ± 0.08) was higher than that of the2-field IMRT (0.53±0.10)(t=7.99,P＜0.05).The HI ofPTV by6-field IMRT (1.36±0.08)waslower than that of 2-field IMRT (2.19 ±0.78) (t =9.04,P ＜0.05).There was no statistical difference in V5,V10,V20 and V35 for ipsilateral lung and in D V35 and D for heart between two plans.Conclusions Compared with 2-field IMRT,6-field IMRT might have a better dose distribution on planning target volume(PTV) for chest wall in postmastectomy breast cancer bulk-recurrence patients,butthere is no significant difference in dose-volume of ipsilateral lung and heart between two plans.

Objective To investigate the diagnosis and the curative effects of interventional therapy by spiral CT in rupture of hepatocellular carcinoma(HCC). Methods 46 patients were checked by spiral CT and abdominal puncture of non-condensable blood. All the patients were treated by the transcatheter arterial embolization (TAE) with iodinated oil and/or gelatin sponge. Results Characteristic findings were detected in 31 patients,of which 7 patients were chiefly detected by spiral CT. The bleeding of ruptured HCCs was controlled effectively in all the cases treated by TAE without serious complications. Conclusion Spiral CT is susceptive to the diagnosis of the ruptured HCC. TAE can be the chiefly treatment in ruptured HCC with fewer serious complications.

Four anthropometric-measurements (weight, height, head ciroumference and chest circumference) of 38342 children aged from birth to 12 years in PLA were made. The results showed that the growth and development of military children conform to the general laws of physicl development of children. The mean weight, head ciroumference and chest ciroumference by age of children aged from birth to 7 years in PLA were higher than that in the nine cities.

Single factor analysis of intelligence test of children aged from birth to 12 years in PLA was made. Results showed that the dangerous factors in mental development included twins, low birth weight neonate, premature neonate, severe asphyxia, encephalitis and medium or severe cranium trauma. On the other hand, many factors (single child in family, comfortable family, better educated raiser and the mother's child-bearing age from 25 to 35 years) could promote mental development. It is indicated that children mental health care were closely related to birth control, perinatal health care and improving economical and culture quality of our country.

Objective To analyze the causes of early death in elderly patients undergoing maintenance hemodialysis ( MHD) and major risk factors.Methods A retrospective study was conducted.Fourty-three patients who had undergone MHD between January 2005 and December 2015 and died within 3 -12 months after hemodialysis in the Hemodialysis Center of China Aerospace Center Hospital were included in Group A while 106 patients who had undergone hemodialysis in the same period but survived for over 12 months were selected as control group(Group B).Results The main causes of early death of 43 elderly patients with MHD were cardiovascular ( 46.5%) and cerebrovascular diseases ( 25.6%) (CCVD), and infections(14.0%).The age,proportion of patients with diabetes and CVD,and the proportion of patients using the central venous catheter( CVC) as vascular access were higher in Group A,but the level of hemoglobin and serum albumin was lower.Indicators of cardiac structure and function showed that the left ventricular end-diastolic diameter (LVDd),left ventricular posterior wall thickness(LVPWT),and left ventricular myocardial quality index(LVMI)in Group A were well above those in Group B, but EF and E/A ratio were significantly lower(P<0.05 and P<0.01).COX regression analysis indicated that the comorbidity with CVD, a lower level of serum albumin and EF were the main risk factors for early mortality in elderly patients under MHD.Conclusion The main cause of early death in elderly MHD patients is CCVD.The comorbidity of CVD, malnutrition and decreased left ventricular systolic function might be the main risk factors for early mortality in elderly MHD patients.Early and adequate dialysis,active treatment of underlying diseases, and the correction of hypoalbuminemia can decrease complications,prolong life and improve the quality of life.
