ObjectiveTo explore the influence of Gaoyu ankang capsule on the water load of ent rants landing at high altitude rapidly and its significance. Methods 80 soldiers who went from plain to high altitude by air for the first time were randomly divided into, experi mental group and control g roup. Experimental group was asked to orally take 2 granules of Gaoyuankang capsule 3 times per day for 3 days before boarding a plane. Control group was not given any pharmaco-prevention. Water load experiment was performed at the fi rst day before and at the third day after landing at high altitude in the tw o groups. Urine quantity of two groups was recorded and compared at various time points in 150 minutes after water was given. Results Urine quantity at each time points in 61～150 minutes after water load experiment beginning and total urine quantity i n corresponding time points remarkably de creased in the control group after landing at high altitude(P

Objective To evaluate the clinical value of MSCTA in displaying the right gastroepiploic artery(RGEA).Methods 16-slice spiral CT enhanced images of abdomen in 80 cases were retrospectively reviewed.The course and the length of RGEA were observed and the diameters of RGEA at the origin and the end were also measured on maximum intensity projection(MIP),thin slice maximum intensity projection(TSMIP) and volume rendering(VR) images.Results The displaying rate of RGEA by MSCTA was 100% including long type in 22 cases(27.50%),moderate type in 53 cases(66.25%) and short type in 5 cases(6.25%).The average length of RGEAs was (19.5±4.5) cm.The average diameters of RGEAs at the origin in long,moderate and short type respectively were (2.69±0.26) mm,(2.70±0.18) mm,(2.68±0.12) mm respectively.The average diameters of RGEAs at the end in these three types were (1.76±0.17) mm,(1.75±0.18) mm and (1.74±0.05) mm respectively.The average diameters of RGEA in different length were no of statistical significance(P＞0.05).Conclusion RGEA can be evaluated with MSCTA before coronary artery bypass grafting.

Parkinson's disease (PD) is a common degenerative disease of the central nervous system, but no drug has been found to be surely able to protect neurons so far, delay onset or slow progression of the disease. Currently there are a variety of Chinese formulas, single herb medicines, active fractions and monomers showed prophylactic and therapeutic effect on PD animal models. The mechanisms include protection of substantia nigra cells, improvement of neurotransmitter content, anti-oxidation, immune regulation, enhancement of Western medicine efficacy, reduction of side effects, etc. All these mechanisms may play integrated effect and slow disease progression. In particular, Chinese medicine compound may have some advantages in neuroprotective treatment of PD, because a variety of active ingredients can exert multi-links, multi-levels and multi-targets integrated regulation effect on human body. However, the level and standard of Chinese medicine studies on PD animal still need to be improved.

Objective To investigate the relationship between peripheral blood thyroxine levels and cardiac function in elderly patients with chronic heart failure.Methods Seventy patients with chronic heart failure admitted into our hospital from January 2016 to December 2017 were enrolled as the study group,and 70 healthy subjects were collected as the control group.Left ventricular ejection fraction(LVEF)and serum thyroxine levels were measured in both groups.Results LVEF,serum levels of total triiodothyronine(TT3)and total thyroxine(TT4)were lower in the study group than in the control group[(37.3±2.4)％ vs.(58.5 ± 5.3) ％,(87.4 ± 8.7) mmol/L vs.(120.8±10.4) mmol/L,(8.6±1.7)mmol/L vs.(10.1 ± 1.3)mmol/L,t =30.486,20.609 and 5.864,P =0.000].LVEF,TT3 and TT4 in patients with grade lⅡ 、grade Ⅲ and grade Ⅳ Cardiac insufficiency were [(42.3±2.2)％、(37.9± 1.0)％ and(31.8±1.5)％,(104.2± 15.4) mmol/L、(89.7±4.6) mmol/L and(72.0±7.2)mmol/L,(9.3± 1.8)mmol/L、(8.8± 1.3) mmol/L and (8.1 ± 0.9) mmol/L]respectively.Serum levels of TT3 and TT4 and LVEF steadily declined as cardiac dysfunction grew more severe in patients with chronic heart failure(P =0.000).Conclusions Patients with chronic cardiac insufficiency are often combined with euthyroid sick syndrome,and serum levels of TT3 and TT4 can indicate the degree of abnormal cardiac systolic function.Therefore,low serum levels of T3 and T4 can be used as indicators for poor prognosis in patients with chronic heart failure.

Objective:To investigate the effect of melatonin (MT) on hypoxia-induced injury of PC12 cells and its mechanism.Methods:PC12 cells cultured in vitro were divided into the control, the hypoxic, and three groups of hypoxic cells combined with different doses (low, medium, and high) of MT at 12.5, 25, and 50 μmol/L, respectively. Cell viability was measured by MTT. The expression of cysteine-containing aspartate 3 (cleaved caspase-3) and SOX2 proteins was detected by Western blot. The expression of SOX2 mRNA was detected by real-time fluorescence quantitative polymerase chain reaction (PCR). The activity of superoxide dismutase (SOD) and content of malondialdehyde (MDA) were detected by the kit. The combined treatment group with the most significant effect was selected as the hypoxia+MT group, and then the effects of hypoxia+MT, hypoxia+siRNA-NC, hypoxia+siRNA-SOX2, hypoxia+MT+pcDNA, and hypoxia+MT+pcDNA-SOX2 on cell viability, apoptosis, protein expression level of cleaved-caspase-3, protein and mRNA levels of SOX2, SOD activity, and MDA levels, respectively, were investigated.Results:Compared with the control group, cell survival rate and SOD activity in the hypoxia group were significantly decreased, while cell apoptosis rate, cleaved caspase-3 protein expression level, MDA content, SOX2 mRNA, and protein expression level were significantly increased (all P<0.05). The effects of low, medium, and high levels of MT and the low expression of SOX2 could ameliorate the above changes induced by hypoxia (all P<0.05), while the overexpression of SOX2 could alleviate the effects of MT on the viability, apoptosis, and oxidative stress of hypoxia-induced PC12 cells (all P<0.05). Conclusions:MT can reduce hypoxia-induced injury to PC12 cells by inhibiting the expression of SOX2.

Objective:To explore the effect of emotion control game based on Snyder hope theory on anxiety of children and their parents.Methods:From June to December 2021, 92 preschool children who received operation and their parents in the Second Affiliated Hospital of Wenzhou Medical University were selected as the study subject. The subjects were divided into two groups according to the time of admission, among which 46 children and their parents admitted from June to September 2021 were taken as the control group, with routine nursing. A total of 46 children and their parents admitted from October to December 2021 were taken as the study group, and emotion control game based on Snyder hope theory was implemented on the basis of the control group. The scores of the Chinese version of the modified Yale Perioperative Anxiety Scale (Cm-YPAS) one day before operation and at the time of entering the Operating Room were compared between the two groups of children, and the scores of the Generalized Anxiety Disorder-7 (GAD-7) and the Newcastle Satisfaction with Nursing Scale (NSNS) of the parents of preschool children one day before operation and at the time of discharge of the two groups were compared.Results:During the intervention, there were 3 cases of dropout children in the study group and two cases of dropout children in the control group, and 43 and 44 children completed the study respectively. The Cm-YPAS scores of children in the two groups at the time of entering the Operating Room were statistically higher than those of children one day before operation; When entering the Operating Room, the Cm-YPAS score of children in the study group was lower than that in the control group, with a statistically significant difference ( P<0.05) . The GAD-7 scores of parents of children in the study group were lower than those in the control group one day before operation and at the time of discharge, and the difference was statistically significant ( P<0.05) . At the time of discharge, the NSNS scores of parents in the study group were higher than those in the control group, with a statistically significant difference ( P<0.05) . Conclusions:In preoperative nursing, emotion control game based on Snyder hope theory for preschool children can effectively reduce their preoperative anxiety, and the anxiety of their parents during perioperative period, and improve parents' satisfaction with nursing.
