Objective:To observe the development of elevated body temperature during surgical correction under different general anesthesias in the pediatric patients with congenital ptosis.Methods:Sixty American Society of Anesthesiologists Physical Status classification Ⅰ pediatric patients with blepharoptosis of both sexes, aged 2-10 yr, undergoing elective surgery for blepharoptosis correction, were divided into total intravenous anesthesia group(TIVA group) and combined intravenous-inhalational anesthesia group(CIIA group) using a random number table method, with 30 cases in each group. Anesthesia was induced with intravenous propofol 1-2 mg/kg, cisatracurium 0.15-0.25 mg/kg and fentanyl 2-3 μg/kg in both groups, and then the patients were endotracheally intubated. Anesthesia was maintained with intravenous infusion of propofol 50-200 μg·kg -1·min -1 and remifentanil 0.2-0.05 μg·kg -1·min -1 in TIVA group and with intravenous infusion of propofol 25-75 μg·kg -1·min -1 and remifentanil 0.2-0.5 μg·kg -1·min -1 and inhalation of 1%-1.5% sevoflurane in CIIA group. After completion of anesthesia induction, the nasopharyngeal temperature was continuously monitored until the end of surgery, and the occurrence of elevation in intraoperative body temperature (≥37.5 ℃) was recorded. Results:The incidence of elevated body temperature was 20% and 40% in TIVA group and CIIA group, respectively. Body temperature ≥39.0 ℃ did not occur in two groups. There was no significant difference in the incidence of elevated body temperature and constituent ratio of degree of elevation in body temperature between the two groups ( P>0.05). Conclusions:When total intravenous anesthesia and combined intravenous-inhalational anesthesia are used in the surgery for blepharoptosis correction in the pediatric patients with congenital ptosis, concurrent mild hypothermia is a non-small probability event, but it is safe to evaluate it in terms of the occurrence of malignant hyperthermia.

Objective:To explore the effect of small private blended teaching combined with guided feedback in the training of specialist nurses in Operating Room.Methods:The cluster sampling was used to select 62 trainees who participated in the training of specialist nurses in Operating Room of the First Affiliated Hospital of Zhengzhou University in 2019 and 2020 as the research object. The trainees in 2019 and 2020 were divided into the control group ( n=32) and the experimental group ( n=30) . The experimental group adopted the small private online course (SPOC) teaching method combined with guided feedback, and the control group adopted the traditional teaching method. After the training, the two teaching methods were evaluated by theoretical assessment, operational assessment and self-designed questionnaires.

The hypoxia-inducible factor is a significant regulator of adaptive transcriptional response in hypoxia or hypoxia. Hypoxia-inducible factor (hypoXIA-inducible factor) loses its activity after hydroxylation by proline hydroxylase in a normoxic environment. Proline hydroxylase inhibitor is a kind of new small molecule oral preparation by inhibiting the proline hydroxylase, reducing the degradation of HIF, activating the hypoxia-induced way, adjusting including stimulates erythropoiesis, iron absorption and mobilization, angiogenesis, lipid, and glucose metabolism, inflammation, energy metabolism, cell growth and differentiation, and other physiological reaction, Showed more clinical benefits. In recent years, the application of proline hydroxylase inhibitors in the field of renal anemia has achieved apparent efficacy, and the research in the field of ischemic heart disease has also made significant progress in the future in the treatment of ischemic heart disease and other aspects of good application prospects.

Vision formation is classically based on projections from retinal ganglion cells (RGC) to the lateral geniculate nucleus (LGN) and the primary visual cortex (V1). Neurons in the mouse V1 are tuned to light stimuli. Although the cellular information of the retina and the LGN has been widely studied, the transcriptome profiles of single light-stimulated neuron in V1 remain unknown. In our study, in vivo calcium imaging and whole-cell electrophysiological patch-clamp recording were utilized to identify 53 individual cells from layer 2/3 of V1 as light-sensitive (LS) or non-light-sensitive (NS) by single-cell light-evoked calcium evaluation and action potential spiking. The contents of each cell after functional tests were aspirated in vivo through a patch-clamp pipette for mRNA sequencing. Moreover, the three-dimensional (3-D) morphological characterizations of the neurons were reconstructed in a live mouse after the whole-cell recordings. Our sequencing results indicated that V1 neurons with a high expression of genes related to transmission regulation, such as Rtn4r and Rgs7, and genes involved in membrane transport, such as Na/K ATPase and NMDA-type glutamatergic receptors, preferentially responded to light stimulation. Furthermore, an antagonist that blocks Rtn4r signals could inactivate the neuronal responses to light stimulation in live mice. In conclusion, our findings of the vivo-seq analysis indicate the key role of the strength of synaptic transmission possesses neurons in V1 of light sensory.

Objective:To estimate the incidence and mortality rates of prostate cancer in China in 2015.Methods:The data from 501 cancer registries in China collected by the National Cancer Center were reviewed and evaluated, and the qualified data were included in the final analysis. According to the national population data in 2015, the nationwide incidence and mortality of the prostate cancer were estimated. Chinese standard population in 2000 and world Segi′s population were used to calculate the age-standardized (ASR) incidence and mortality rates (ASR China and world, respectively).Results:After data review, the data reported by 368 registries were included in the final analysis, covering a total population of 309 553 499, accounting for 22.52% of the national population at the end of 2015. There were 72 thousand new prostate cancer cases estimated in China in 2015, with a crude incidence rate of 10.23/100 000. The ASR China and ASR world are 6.59/100 000 and 6.47/100 000, respectively, which is the sixth incidence of male malignant tumor.The estimated number of prostate cancer death was 3.07 thousand in China in 2015, with a crude mortality rate of 4.36/100 000; The ASR China and ASR world mortality rates were 2.61/100 000 and 2.65/100 000, respectively, which is the tenth leading cause of death in male malignant tumor.The ASR China incidence and mortality of prostate cancer in males were higher in urban areas (8.40/100 000 and 3.11/100 000) than those in rural areas (4.16/100 000 and 1.90/100 000). The incidence and mortality rates in the eastern areas (8.54/100 000 and 2.99/100 000) were higher than those in the central (5.28/100 000 and 2.34/100 000) and western areas (5.32/100 000 and 2.37/100 000) of China.Conclusions:The incidence and mortality rates of prostate cancer in China are lower than the global average, but there is an increasing trend. The incidence and mortality of prostate cancer in China have obvious regional differences.

Objective:To explore the spatial clustering and trend of liver cancer mortality in different counties of Shandong province from 1970 to 2013, and provide scientific basis for the development of liver cancer prevention and control plan.Methods:Cancer mortality data were obtained from Shandong Death Registration System and three national death cause surveys in China. Mortality rate and age adjusted mortality rate were used to describe the trend of liver cancer in different years. Difference decomposing method was applied to estimate the contribution of demographic and non-demographic factors to the change of mortality. Software ArcGIS 10.2 was used for spatial analysis, and software SaTScan 9.4 was used for spatial clustering analysis on liver cancer mortality.Results:From 2011 to 2013, the crude mortality rate of liver cancer (29.89/100 000) in Shandong increased by 208.00 % and 35.37 % respectively compared with that during 1970-1974 (9.72/100 000) and 1990-1992 (22.08/100 000) and was similar to that during 2004-2005 (30.44/100 000). While age standardized mortality rate (ASMR) increased first and then decreased. The ASMR during 2011-2013 (12.62/100 000) increased by 60.97 % compared with that during 1970-1974 and decreased by 22.38 % and 21.81 % compared with that during 1990-1992 and 2004-2005, respectively. According to the difference decomposition analysis on liver cancer mortality in different years, the contribution of population factors to the liver cancer mortality rate increased from 3.38 % during 1990-1992 to 29.36 % during 2004-2005 and 46.16 % during 2011-2013. However, the contribution of non-population factors to the increase of liver cancer mortality decreased. According to the spatial distribution of liver cancer mortality, the crude mortality rate of liver cancer in different counties were quite different, ranging from 9.33/100 000 to 65.33/100 000. Using the spatial scanning statistical software to analyze the spatial clustering of liver cancer mortality, multi areas with high mortality rate of liver cancer were found, and they were mainly distributed in Jiaodong peninsula from 2011 to 2013, covering 20 counties (cities, districts) in Qingdao, Yantai and Weihai. The risk of liver cancer mortality in this area was 1.54 times higher than that in other areas. The spatial clustering distribution of liver cancer mortality during 1970-1974 was significantly different from that during 2011-2013, the areas with high mortality rate during 1970-1974 were mainly distributed in central and western Shandong. Conclusions:There were significant temporal and spatial distribution changes in the mortality rate of liver cancer in Shandong from 1970 to 2013. According to these trends and their geographical and spatial distribution, we should further explore the risk factors of liver cancer, and formulate feasible and area specific prevention and control measures for liver cancer.
