OBJECTIVETo investigate the changes of the cardiac hemodynamics after acute high altitude exposure in healthy young males and the relationship with acute mountain sickness(AMS).

METHODSLeft ventricular function and oxyhemoglobin saturation (SaO2), heart rate (HR), blood pressure (BP) were measured in 218 healthy young males before and after high altitude exposure within 24 h respectively. According to the lake louise score criteria, the subjects were divided into two groups: acute mountain sickness group (AMS group) and non acute mountain sickness group (non-AMS group).

RESULTSHR, diastolic blood pressure (DBP), mean arterial pressure (MAP), left ventricular ejection fraction (LVEF), stroke volume (SV), stroke index (SI) cardiac output (CO), cardiac index (CI) were significantly increased upon acute high altitude exposure (P < 0.05). Whereas SaO2 and end-systolic volume (ESV) were significantly decreased (P < 0.05). In addition, HR, systolic blood pressure (SBP) and MAP in AMS group were significantly higher than those in non-AMS group (P < 0.05). But stroke index (SI) and end-diastolic volume (EDV) in AMS group were significantly lower than those in non-AMS group (P < 0.05).

CONCLUSIONCardiac function in healthy young males upon acute high altitude exposure was enhanced. EDV, HR and SI might become the indexes of predicting the acute mountain sickness in the future.

BACKGROUND: Echinococcosis alveolaris were not easily discovered in prophasel Although used various kinds of imaging and immunity test, misdiagnosis rate of echinococcosis alveolaris was still high.OBJECTIVE: To study radioimmunoimaging of ~(131)Ⅰ-labelled anti-alveolar hydatid polyclonal antibody in the rat model with Echinococcus multilocularis in vivo.METHODS: Totally 36 Wistar rats were randomly divided into 3 groups. A group included 12 alveolar echinococcosis rats, B group included 12 normal rats, C group included 12 alveolar echinococcosis rats. Rats in the A and B group were injected intrapedtoneally 1 mL ~(131)Ⅰ-labelled anti-alveolar echinococcosis polyclonal antibodies (37 MBq), those in the C group were injected intraperitoneally I mL ~(131)Ⅰ-(37 MBq). All rats were imaged 24, 48, 72, 96 hours later with ECT to measure region of interest (ROI) of alveolar hydatid. The unit weight radioactive counts per minute of three group rats organs were measured after 96 hours, and the targetto-nontarget (TINT) ratios were calculated in A group rats.RESULTS AND CONCLUSION: In A group rat inoculated right lobe of liver alveolar echinococcosis, radioactive parts of the distribution could be seen. And ROI of alveolar echinococcosis were the highest at 72 hours. After dissection the locations were in line, and it was no significant radioactive liver distdbution in B and C group. Rats were sacrified after 96 hours, in vitro determination of radioactive counts show that A group echinococcus multilocularis was (18.610±3.401)x10~3 cpm/g, which was greater than organs except thyroid and gastric tissues (P ＜ 0.001). The rest of organize T/NT ratios were greater than 1.28 apart from the thyroid and gastric tissues. The difference of unit weight radioactive counts per minute of three group had no obviously significance except the polypide tissues (P ＞ 0.05). This proves that ~(131)Ⅰ-1abelled anti-alveolar echinococcosis polyclonal antibodY successfully combinated with alveolar echinococcosis.

Objective To investigate the effect of microcireulation blood flow and altering immunity by Chuanxiongqin,ulinastain and thymosin α1 on sepsis patients.Methods 90 patients were randomly divided into 3 groups(n=30),namely ICU group,Chuanxiongqin group,ulinastain and thymosin α1 group.HLA-DR/CD14+and IL-6,TNF-α,Lac,DD were measured.Results (1)DD showed no significant difference at every time point between ICU group and ulinastain+thymosin α1 group(P＞0.05).DD decreased in Chuanxiongqin group,and was significantly different from the others on the third day.(2)Lac unchanged significantly at every time point in ICU group(P＞0.05).Lac in Chuanxiongqin group and ulinastain+thymeain α1 group tended to decrease,and was statistically different from ICU group on the second day.(3)IL-6 and TNF-α tended to increase at every time point in ICU group(P＜0.05).In ulinastain+thymosin α1 group,IL-6 and TNF-α returned to the level before treatment,HLA-DR/(D14+increased significantly,and was higher than Chuanxiongqin group and ICU group statistically.Conclusion Chuanxiongqin could ameliorate circulation;ulinastsin and thymosin α1 could depress IL-6,TNF-α.So ulinastain and thymosin α1 might protect the immunity of sepsis patients.
