Objective:To study the eftect of plateau environment on the body compositions of soldiers.Methods:A total of 120 male soldiers were selected for the study.All of the study subjects received a physical examination between June and November in 2014.Bio-electrical impedance technique was used to measure the subjects' body composition including 33 parameters such as body mass index (BMI) and body fat mass.Results:Compared to that before entering into the plateau,the levels of 31 parameters were significantly lower after entering into plateau,except the distribution of muscles in left lower limb and ECW/TBW in right upper extremity.Conclusion:The body compositions of soldiers may decrease under plateau environment.This phenomenon need to be interfered purposefully to aTange scientific diets and training intensity.

Vascular birthmarks are the most common disease.The morbidity is about 2.5%,most of the lesions occur in oral and maxillofacial regions which accounts for 40%-60% of the total lesions.In 1982,Mulliken and Glowacki proposed a biologic classification of vascular birthmarks on the basis of their clinical manifestations,histopathological features,and natural history.They defined hemangiomas as vascular tumors with a growth phase,marked by endothelial proliferation and hypercellularity,and an involutional phase.They recognized that many entities referred to as hemangiomas are actually structural malformations of the vasculature,derived from capillaries,veins,lymph vessels,or arteries or from a combination of these sources.The classification was confirmed and issued by International Society for the study of vascular anomality(ISSVA) in 1988.Waner and Suen amended the above category in 1995.This paper presents the new classification of vascular birthmarks and the developments in this field in re-cent years,including the pathology,clinical features and the therapy.For example,the classification of venular malformation categorized by Waner in 1989;the classification of lymphous malformation by Waner and Suen in 1995;and the treatments according to above classifications.

AIM: The experiment was designed to study the effect of compound Danshen dripping pills (DSDP) on myocardium with anoxin/reoxygenation. METHODS: The myocardial anoxin/reoxygenation model was made in perfused isolated rat heart. DSDP and isosorbide dinitrate (ID) were given at the time of pre-perfusion and reperfusion, then HPLC and H-600 electron microscope were used to detect the change of high energy phosphate and the ultrastructure of myocardial cell. RESULTS: ① The contents of AMP, ADP, ATP and AN in myocardium in only anoxin/reoxygenation group were obviously lower than those in the control group (P0.05). ③ In the groups with ID, the contents of AMP, ADP, ATP and AN were distinctively lower than those in the control group (P

Objective:To investigate the safety, efficacy and application indication of intra-operative cell salvage (IOCS) in cesarean section.Methods:A total of 1 265 pregnant women who received IOCS blood transfusion during cesarean section in 11 tertiary A hospitals from August 2016 to January 2019 were collected and divided into <1 500 ml group (796 cases) and ≥1 500 ml group (469 cases) according to the amount of blood loss during cesarean section. The general clinical data, ultrasonic imaging data, perinatal and puerperium indicators were analyzed retrospectively. The risk factors of intraoperative blood loss ≥1 500 mL using IOCS transfusion were analyzed by logistic multivariate regression.Results:(1) A total of 848 001 ml of blood was recovered and a total of 418 649 ml of blood was transfused in 1 265 pregnant women who received IOCS transfusions, which was equivalent to 23 258 U red blood cell suspension, greatly saving medical resources. The intraoperative blood loss in <1 500 ml group and ≥1 500 ml group was 800 ml (300-1 453 ml) and 2 335 ml (1 500-20 000 ml), respectively. No amniotic fluid embolism, severe adverse reactions, shock and death occurred in the two groups. (3) Multivariate regression analysis showed that age ≥35 years ( OR=1.5, 95% CI: 1.1-1.9), prenatal hemoglobin level <110 g/L ( OR=1.7, 95% CI: 1.3-2.2), history of uterine surgery ( OR=1.8, 95% CI: 1.3-2.6), placenta previa ( OR=1.9, 95% CI: 1.1-3.1), placenta accreta ( OR=2.6, 95% CI: 1.8-3.9), blood pool in the placenta ( OR=1.6, 95% CI: 1.1-2.3), abnormal posterior placenta muscle wall ( OR=1.8, 95% CI: 1.2-2.6), placenta projecting to the anterior uterine wall ( OR=3.0, 95% CI: 1.3-7.0) were risk factors for blood loss ≥1 500 ml in obstetric transfusion using IOCS technique, with statistical significance (all P<0.05). Conclusion:IOCS is safe and effective in cesarean section, which could save the medical resources and reduces medical expenses, however, it is necessary to strictly master the application indication.

With an improvement in the long-term survival rates of cancer patients, the requirements for fertility protection of young cancer patients after chemotherapy are increasingly prominent. Early studies have shown that gonadotropin-releasing hormone agonist (GnRHa) has a protective effect on fertility. But in recenct year, relevant studies have shown that its protective effect is controversial. This article reviews the clinical researches of GnRHa for fertility protection in patients with common tumors, and explores its evidence-based medicine, in the hope of providing references for reasonable clinical application.
