Objective To observe the effect of levosimendan in the treatment of pulmonary heart disease patients with heart failure.Methods 60 patients were randomly divided into treatment group and control group.The treatment group used levosimendan.The control group used digitalis.We observed the NT -PROBNP, echocardio-graphic and clinical efficacy.Adverse drug reactions were observed too.Results The significantly effect of the treat-ment group was 22 cases(73%),and effective was 8 cases (27%).The significant effect of the control group was 14 cases (43%),and effective was 16 cases (57%).The levels of NT-PROBNP and pulmonary artery pressure in the treatment group were ( 416 ±311 ) pg/mL, ( 51 ±9 ) mmHg after 1 month treatment, which in the control group were (1 516 ±250) ng/mL,(57 ±10) mmHg.The efficacy of the treatment group was better than the control group (χ2 =4.44,P<0.05),the levels of NT-PROBNP and pulmonary artery pressure were lower(t=15.10,2.44,all P<0.05).Conclusion The levosimendan had effects on the pulmonary heart disease patients with heart failure.

0.05～0.2?l of HRP (Sigma Ⅵ) were introduced into the periaqueduetal gray (PAG) of 45 rats at the superior collicular level, each brain was sectioned and processed with DAB, BDHC, O-D and TMB reactions. 29 were chosen for analysis and according to the locations of the injection center and the extent of reaction, were divided into 3 groups:1. The injection center was found in the lateral part of PAG; the reaction only involved a small area within PAG (11 rats), labeled cells were seen in PAG, tectum, reticular formation (RF) and dorsal raphe nucleus.2. The injection center was in the dorsolateral part of PAG; the reaction area extended out of PAG to the nearby RF and tectum (9 rats); labeled cells were seen in the structures mentioned in group 1 as well as in habenular nucleus (hn), parafascicular nucleus (PFN), hypothalamic nuclei (anterior, posterior, ventromedial, dorsomedial, lateral), thalamic nuclei (lateral, reticular, medial part of ventral nucleus), paraventricular gray (PVG), nucleus of the optic tract, nucleus of posterior commissure (NPC), parabigeminal nucleus (PBN), locus ceruleus, ventral nucleus of lateral geniculate body, entopeduncular nucleus.3. The injection center was in the lateral or ventrolateral part of PAG, the reaction area extended to the nearby RF, tegmentum and part of tectum (9 rats), labeled cells were seen in the structures mentioned in group 1 as well as in substantia nigra, H_1, H_2, zona inserta, HN, PFN, PVG, NPC, PBN, locus ceruleus, pretectral area and nuclei of hypothalamus. In this group 3 rats were processed with TMB reaction. Labeled cells were seen not only in the above-mentioned structures but also in the deep layers of anterior cingulate cortex (areas 23 and 24), nucleus raphe magnus, nucleus reticularis gigantocellularis, periventricular gray of 4th ventricle, dentate nucleus of cerebellum, lamina Ⅴ～Ⅶ of cervical spinal cord (the other segments were left out), preoptic and supraoptic nuclei, suprachiasmatic nucleus, anterior nucleus of mammillary body, medial nucleus of amygdaloid nucleus, spinal nucleus of nerve Ⅴ. The labelled cells were seen chiefly in the ipsilateral side. Neuronal connections also were analysed according to the disparity in labelled structures.

OBJECTIVE: To provide information for clinical rational and safe use of albendazole.METHODS: The medical database and network both at home and abroad were searched and the data regarding the research and development,the market information and indications of albendazole were analyzed.RESULTS & CONCLUSIONS: 5 dosage forms of albendazole are available in the market: tablets,capsules,granules,oral liquid,and syrup.The sales amount of albendazole in recent years dominated the first 3 places in domestic antiparasites market.There are a total of 39 domestic manufactures for albendazole,which can be used to treat 21 kinds of human parasitosis.Its clinical application is widespread.However,severe adverse drug reactions such as the rare encephalitis syndrome and allergic shock etc induced by albendazole pose hidden risks for treatment;therefore,management on its use should be strengthened.

Objective:To review literature reports of varieties of ADRs induced by mebendazole to provide a sci- entific foundation for clinical revaluation of mebendazole.Method:The related literatures in the internal and external medi- cine medical database in 1994-2004 were explored,and then both analysis and statistics were conducted with the methods of epidemiolngy and literature analysis.Result:ADRs induced by mebendazole could be involved in multiple organs.Most victims were children and the elderly.Their latent periods were determined by the types of ADRs,which had a variety of forms.Conclusion:Mebendazole was potentially unsafe.So we should strengthen our rational drug use and post-marketing revaluation of safety.

Objective To investigate the clinical effect of resuscitating acupuncture and scalp acupuncture on neurological function and high sensitivity C reactive protein (hs-CRP) in serum in patients with acute cerebral infarction. Methods 90 patients with acute cerebral infarction were divided into three groups: drug, routine acupuncture and resuscitating acupuncture and scalp acupuncture groups in random. They were evaluated with NIH Stroke Scale (NIHSS) , Modified Rankin Scale (MRS) 0, 7, 14 d after treatment, and measured with the levels of hs-CRP. Results There were significant improvements for NIHSS and MRS scores in the resuscitating acupuncture and scalp acupuncture group compared with those of the others, as well as the levels of hs-CRP. Conclusion Resuscitating acupuncture and scalp acupuncture can reduce the level of hs-CRP and improve the neurological functions in patients with acute cerebral infarction.

ObjectiveTo evaluate the enteral nutritional schemes for patients with acute cerebral infarction in effectiveness and economy. Methods117 acute cerebral infarction patients with dysphagia were divided into 3 groups. Homogenized diet, sequential intestinal nutrition and intestinal integral protein were provided respectively for these groups by nasogastric tube feeding. The clinical effectiveness was evaluated and the cost-effectiveness analysis was done pharmacoeconomically 14 d later. ResultsThe effective rates of these schemes were 42.5%, 75% and 49%, while the cost-effectiveness ratios were 9.84, 29.37, 42.16 respectively. ConclusionFor the acute cerebral infarction patients with dysphagia, the scheme of sequential intestinal nutrition is most effective, and the homogenize diet is most economical.

Objective:To investigate the application of a video laryngoscope combined with a fiberoptic bronchoscope in emergency endotracheal intubation and its effects on pulmonary infection in patients with craniocerebral trauma.Methods:A total of 105 patients with craniocerebral trauma who received treatment in Yiwu Central Hospital from January 2020 to December 2020 were included in this study. They were randomly allocated to undergo endotracheal intubation with a video laryngoscope (control group, n = 50) or a video laryngoscope combined with a fiberoptic bronchoscope (observation group, n = 55). Glottic exposure, intubation, vital signs, lung infection rate during hospitalization, and incidence of complications were monitored/determined in each group. Results:Glottic exposure in the observation group was superior to that in the control group ( Z = 4.29, P < 0.001). First-pass success rate was significantly higher in the observation group than in the control group [96.36% (53/55) vs. 82.00% (41/50), χ2 = 5.76, P < 0.05]. The number of intubation attempts and the time to successful intubation were (1.07 ± 0.53) times and (85.12 ± 15.36) seconds, respectively in the observation group, which were significantly less or shorter than those in the control group [(1.92 ± 0.74) times, (106.13 ± 16.34) seconds, t = 6.81, 6.79, both P < 0.001). The changes in mean arterial pressure and heart rate during intubation were less in the observation group than in the control group (both P < 0.05). The amplitude of increase in blood oxygen saturation after intubation was greater in the observation group than in the control group ( P < 0.05). Lung infection rate was significantly lower in the observation group than in the control group [10.91% (6/55) vs. 30.00% (15/50), χ2 = 5.96, P < 0.05]. The incidence of complications was significantly lower in the observation group than in the control group [5.45% (3/55) vs. 18.00% (9/50), χ2 = 4.07, P < 0.05]. Conclusion:Application of a video laryngoscope combined with a fiberoptic bronchoscope in emergency endotracheal intubation can increase the first-pass success rate, reduce repeated intubation attempts, shorten time to successful intubation, help to maintain stable vital signs, prevent lung infection and complication. Therefore, the combined method is of clinical application value.

Objective: To understand the confidence-related factors of refusing unprotected sex behavior among college students in Zhejiang province. Methods: Stratified cluster random sampling method was conducted among college students from 13 colleges and universities in Zhejiang province, from October to November, 2018. A total of 3 718 students who self-reported "ever having had sexual contacts" were enrolled. Chi-square test was used to compare the confidence of rejecting unprotected sex under different demographic characteristics, sexual attitude/behaviors and different intervention approaches. Multivariate logistic regression model was used to analyze the related factors. Results: A total of 3 718 college students were involved in this study with average age as (20.17±1.38) years old and 70.5% (2 620/3 718) were male. The proportions of having confidence to refuse unprotected sex behavior were 74.9% (1 963/2 620) of male and 77.9% (896/1 098) of female students, respectively. According to the results from multivariate logistic regression analysis, factors that related to the confidence of refusing unprotected sex behavior in male students would include, did not accept casual sex behavior (compared with accepted students, OR=2.247, 95%CI: 1.828-2.762), did not accept homosexual behavior (compared with accepted students, OR=1.810, 95%CI: 1.302- 2.516), having casual sex behavior in the past one year (compared with having no sex behavior, OR=1.345, 95%CI: 1.051-1.721), aware of the availability of HIV self-test reagents service in college (compared with did not knew, OR=1.381, 95%CI: 1.011-1.887), having taken the HIV infection risk self-assessment in college (compared with did not take, OR=1.707, 95%CI: 1.374-2.121). In female students, the factors would include: being urban resident (compared with rural residence, OR=1.816, 95%CI: 1.225-2.693), 21 years old or above (compared with 20 years old or below, OR=1.469, 95%CI: 1.075-2.007), having taken the HIV infection risk self-assessment in college (compared with did not take, OR=1.597, 95%CI: 1.093-2.333), etc. Conclusions Both male and female college students had higher confidence in refusing unprotected sex behavior. For male students, refusing casual or homosexual contacts, having casual sex in the recent year, knowing HIV self-test reagents service and having had HIV-related risk self-assessment in college as related factors. However, for female students; city residence, 21 years old and above, and having a HIV infection risk self- assessment in college appeared as related factors. Sexual health education should be strengthened to reduce unprotective sex behavior and to promote HIV infection risk self-assessment among the college students.
