In order to study the mechanism of the barrier functional impairment-of gastric mucosa after burus, phosphorus or napalm 30% TBSA Ⅲ? burns was inflicted to rats and the osmolarity of hydrogen and chlorine ions of their gastric lavage fluid was determined. It was found the concentrations of the 2 ions in the lavage fluid decreased immediately after burn injury, reached the lowest point in the 5th hour postburn, and did not return to its preburn level even in the 72nd hour postburn.It is considered by the authors that the lowering of hydrogen and chlorine ions in the gastric lavage fluid after burns results from the reversed diffusion of the ions into the gastric mucosa since the stress reaction of the organism towards severe burns can impair the barrier function of the gastric musosa and the increase of hydrogen ions in gastric mucosa can aggravate the function impairment. In addition, phosphorus is a cytoplasm toxic. It can be rapidly absorbed through the cutaneous tissue of the burned area and carried to the gastric mucosa to intensify the mucosal lesion.

usually in the 24th to 72nd h postburn.There was edema associated with mild necrosis of the duodenal mucosa immediately after burns.Severe necrosis occurred in the 2nd h postburn.The manifestations reached the peak in the 24th h and were alleviated in the 72nd h postburn.As a rule,the damages on the duodenal mucosa occurred early and persisted for a long period with high incidence and severe wounding conditions.The damages of gastroduodenal mucosa were more severe in the phosphorus burn group than in the napalm burn proup mainly because of the more intense heat stress after phosphorus burns and the tosicity of the element phosphorus and phosphorus free redicals.

Male Wistar rats were randomized into 3 groups:The rats of group I received sham burning to serve as the control and those of groups and Ⅲ were inflicted with 20% and 30% TBSA third degree phosphorus burns respectively.No treatment was given to group Ⅱ.Group Ⅲwas further divided into 2:The rats of subgroup Ⅰ were debrided immediately and those of subgroup Ⅱ in the 6th hour postburn.The findings were as follows;(l)The tissue content of phosphorus was more significantly decreased in subgroup Ⅰ than in subgroup Ⅱ-(2)Twenty-eight rats of subgroup Ⅰ all survived while 9 of the 44 rats of subgroup Ⅱ died with a mortality rate of 20.5%.The mortality rate of group Ⅱ was 37.5%(3/8).(3)The recovery of serum electrolytes and other biochemical parameters occurred earlier in subgroup I.Our findings suggest that debridement as early as possible after phosphorus burns contributes significantly to the decrease of the victims mortality.

OBJECTIVE: To observe the effects of Cili juice enriched with SOD (CLJES) on lead excretion, activity of superoxide dismutase (SOD) in erythrocytes, plasma lipid peroxidation (LPO) and immune function in experimental lead poisoning animals. METHODS: Lead poisoning models were made in rats and mice. The effects of CLJES on lead excretion, SOD activity, LPO concentration in rats and immune functions in mice were determined and compared with those of conventional EDTA treatment. RESULTS: CLJES significantly increased lead excretion. Furthermore it significantly increased SOD activity, reduced LPO concentration in rats with lead poisoning and enhanced immune function in lead loaded mice, however EDTA had no such actions. CONCLUSION: CLJES might exert a wider range of therapeutic effects on lead poisoning than EDTA.

Objective To investigate the prevalence rate of hypertension among the elderly population in Shanxi Province. Methods According to the random sampling, 41 residents committees of city blocks and villages of 9 areas (including Taiyuan, Datong, Jinzhong, Yuncheng, et al) of Shanxi Province were extracted as the investigative spots. All the people were older than 55years, and risk factors for hypertension were identified. Results A total of 3702 people were surveyed, including 1,782 men and 1,920 women. The total hypertension prevalence rate was 39.0%(the standardized rate: 39. 5 %), with 38. 7 % in men (the standardized rate: 38. 5%), 39.3 % in women (the standardized rate: 41.2%), and no statistic significance was found between men and women (χ2= 0. 143, P>0. 05). Aging, lacking of knowledge, and obesity were risk factors for hypertension. Conclusions The hypertension in Shanxi Province has a high prevalence rate among the elderly population, a comprehensive intervention should be taken in the prevention of hypertension.

Objective: To detect the expression of SIRT1 and Ac-FOXO1 in rats after endurance training and acute exhaustive exercise, and explicit the myocardial protective effect of SIRT1. Methods: Rats were randomly divided into four groups: control group(n=20), exhaustive exercise group (E group, n=20), exhaustive exercise group + endurance training (TE group, n=18), exhaustive exercise group + endurance training + selective SIRT1 inhibitor (TSE group, n=17). The Control and E groups were fed routinely for 5 weeks. The TE and TSE groups were subjected to swimming exercise for 5 weeks for endurance exercising. The TSE group was intraperitoneally injected with selective SIRT1 inhibitor Sirtinol(2 mg/kg) at 30 minutes before endurance exercising. The E, TE and TSE groups were subjected to exhaustive exercise. The myocardial tissues of rats were collected after exhaustive exercise. Real-time polymerase chain reaction (PCR) and Western blot analysis were performed to detect the myocardial mRNA and protein expressions of SIRT1 and Ac-FOXO1. The myocardial protein expression of Bax and Bcl-2 was also detected by Western blot. Terminal-deoxynucleoitidyl transferase mediated nick end labeling (TUNEL) assay was used to assess the apoptosis of myocardial cells. Results: Compared with Control group, the SIRT1 and Bcl-2 expression in the myocardial tissue was obviously decreased, while the Ac-FOXO1, Bax, and the myocardial cell apoptosis were significantly increased in E group (all P<0.01). Compared with E group, the expression of SIRT1 and Bcl-2 was obviously up-regulated (both P<0.01), while the Ac-FOXO, Bax and the myocardial cell apoptosis was significantly reduced in TE group (all P<0.01). Compared with TE group, the SIRT1 and Bcl-2 expression was obviously lower (both P<0.01), while Ac-FOXO1, Bax, and the cell apoptosis were significantly higher in group TSE (all P<0.01). Conclusion Endurance training could protect myocardium by reducing the myocardial oxidative stress injury and apoptosis via activating SIRT1 signaling pathway, up-regulating the myocardial expression of SIRT1 and regulating the deacetylation of FOXO1.

Objective:To observe the clinical effects of aspirin combined with low-molecular-weight heparin in the prevention of preeclampsia in patients with hypertension during pregnancy.Methods:From October 2017 to December 2018, 120 patients with hypertension during pregnancy who were treated in the Maternal and Child Health Hospital of Cixi were selected.The patients were divided into control group and observation group according to the wishes of pregnant women and informed consent, with 60 patients in each group.Control group received single oral aspirin 100 mg daily from 11-13 + 6 weeks of pregnancy to 36 weeks of pregnancy or 5-10 days before termination of pregnancy.The observation group received 3075 IU of low-molecular-weight heparin subcutaneous injections daily from 11-13 + 6 weeks of pregnancy for 2 weeks, and was orally given aspirin 100 mg daily for 36 weeks or until 5-10 days before termination of pregnancy.The incidence of preeclampoia, adverse pvegnany outcome and complication of the two groups were observed and compared. Results:The incidences of preeclampsia, preterm birth, cesarean section, fetal distress, placental abruption and neonatal asphyxia in the observation group were 15.00%, 20.00%, 36.67%, 11.67%, 6.67% and 1.67%, respectively, which were significantly lower than those in the control group (31.57%, 35.00%, 55.00%, 30.00%, 23.33% and 15.00%, χ 2=4.658, 4.104, 4.061, 6.113, 6.535, 6.981, all P<0.05). The gestational age at delivery[(37.88±3.72)weeks] and the weight of the newborn [(2.63±0.24)kg] in the observation group were significantly larger than those in the control group[(36.11±3.59)weeks, (2.13±0.20)kg]( t=2.652, 12.397, all P<0.05). The incidences of postpartum blood loss, thrombocytopenia, oligohydramnios and pleural and ascites in the observation group were 5.00%, 1.67%, 5.00% and 16.67%, respectively, which were significantly lower than those in the control group (25.00%, 16.67%, 23.33% and 15.00%, χ 2=9.411, 8.106, 8.292, 6.981, all P<0.05). Conclusion:Low-dose aspirin and low-molecular-weight heparin for patients with hypertension during pregnancy can reduce the incidence of preeclampsia and improve adverse pregnancy outcomes, which is worthy of promotion and application.

BACKGROUND: The curative potential of various bronchoscopic treatments such as electric snare, carbon dioxide freezing, argon plasma coagulation (APC), Neudymium-dopted Yttrium Aluminium Garnet (Nd:YAG) laser and photodynamic therapy (PDT) for the treatment of intraluminal tumor has been administered previously, but this regimen is not common in the treatment of typical carcinoid. The aim of this study is to investigate the curative effects both in short-term and long-term of interventional bronchoscopy in the treatment of typical carcinoid. METHODS: We retrospectively reviewed the clinical data of typical carcinoid patients who were treated with interventional bronchoscopy for tumor suppression and they were hospitalized in the Emergency General Hospital from December 2010 to December 2020, and Wilcoxon rank sum test and chi-square test were used for analysis. RESULTS: A total of 32 patients were included, including 18 cases of preoperative bronchial artery embolization (embolization rate 56%, 95%CI: 31%-79%). The grade score of dyspnea decreased from before treatment to after treatment, and the difference was statistically significant [(1.44±1.03) score vs (0.25±0.58) score, P=0.003]; The degree of bronchial stenosis decreased from pre-treatment to post-treatment, and the difference was statistically significant [(87.50%±13.90%) vs (17.50%±6.83%), P<0.001]; There was significant difference in bronchial diameter before and after treatment [(0.14±0.18) cm vs (0.84±0.29) cm, P<0.001]. CONCLUSIONS Bronchoscopic interventional therapy has significant short-term and long-term effects in the treatment of typical carcinoid.

Non-occupational post-exposure prophylaxis (nPEP), a biological means to block the transmission of HIV, is recommended by European countries, USA and WHO to use in HIV high-risk groups, but its utilization rate is still very low. The information-motivation-behavioral skills model (IMB) can accurately explain the prevalence and change of health behaviors. Based on this model, this paper summarizes the progress in research of the influencing factors for nPEP use to provide a basis for further research to promote the use of nPEP.
