[Summary] This paper reported the surgical cooperation in 72 cases of da Vinci robot operations between September 2014 and December 2014 in this hospital .All the 72 cases of total laparoscopic operation by using the da Vinci robot assistance were successfully completed, without robot faults caused by mismatch and nursing complications caused by improper nursing .We believe that nurse training with robot surgical system and qualification certification , preoperative patient visits , reasonable arrangement of operation room , careful observation with skilled coordination with the robot , proper postoperative placement of the robot , and maintenance and disinfection of the machine are crucial to a successful surgery .

Aim To study the anti-oxidative and mitochondria-protective effects of estract of astragalus (EA ) on focal cerebral ischemia-reperfusion injury and its mechanism in rats.Methods Middle cerebral artery occlusion(MACO) was used to induce focal cerebral ischemia-reperfusion model. After 24 h reperfusion,MDA, LD content and SOD activity of brain homogenate were tested. MDA content,SOD and ATPase activity in mitochondrion were also tested.Transmission electron microscopy was used to assess the ultrastructure dstruction. Results EA(20, 40, 80 mg?kg -1) significantly inhibited the increase of MDA, LD after cerebral ischemia-reperfusion. EA (40, 80 mg?kg -1) also inhibited the decrease of activit of SOD in rats. EA(20, 40, 80 mg?kg -1) inhibited the increase of MDA and inhibited the decrease of activities of SOD, Na+,K+-ATPase, Ca 2+,Mg 2+-ATPase in mitochondrion. The examination by transmission electron microscopy showed that EA (20, 40 mg?kg -1) protected the ultrastructure destruction. Conclusion EA had protective effects against focal cerebral ischemia reperfusion injuries via attenuating cerebral oxygen free radical(OFR)lipid peroxidation and protecting mitochondria.

Objective:To explore the predictive value of amplitude integrated electroencephalography(aEEG)in the neurological prognosis of children with neonatal bacterial meningitis(NBM).Methods:The clinical data and aEEG results from 148 children diagnosed with NBM who completed aEEG examinations in the Department of Neonatology at Kunming Children′s Hospital from January 2018 to December 2019 were retrospectively analyzed.According to whether aEEG is abnormal, the children were divided into aEEG abnormal group and aEEG non-abnormal group.According to the degree of aEEG abnormality, children with aEEG abnormality were divided into aEEG mild abnormal group and aEEG severe abnormal group.The abnormal rate and abnormal characteristics of aEEG were analyzed; The clinical data of two groups were compared.Results:(1)Among the 148 children with NBM, 49 children had abnormal aEEG, 99 children had no abnormality, and the aEEG abnormal rate was 33.1%.The abnormal aEEG was manifested as delayed sleep-wake cycle maturation in 39 (26.3%) cases, abnormal discharge in eight (5.4%) cases, and abnormal background activity in one (0.6%) case.(2)The proportion of children with convulsive seizures and refractory NBM in aEEG abnormal group were significantly higher than those in aEEG non-abnormal group ( P<0.05). In the routine and biochemical abnormal indexes of cerebrospinal fluid, the proportion of protein >3 g/L, cerebrospinal fluid leukocyte>500×10 6/L, cerebrospinal fluid glucose<1.5 mmol/L, positive cerebrospinal fluid culture, positive blood and cerebrospinal fluid culture, abnormal head MRI in aEEG abnormal group significantly increased ( P<0.05); While there was no significant difference regarding blood routine leukocyte abnormality, CRP increase, and positive blood culture ratio between two groups ( P>0.05). (3) 148 cases of NBM children were followed up to 15 months old, 119 (80.4%) cases completed the follow-up, the loss rate was 19.6%, three cases died, and 11 cases had psychomotor retardation.Compared with the children with abnormal aEEG, the prognosis of children with NBM was significantly different, the Spearman rank correlation coefficient r was 0.315 ( P<0.05). COX regression was used to analyze the predictive value of each index for adverse outcomes. Abnormal aEEG was an independent risk factor for adverse outcomes in children with NBM ( OR=7.452, 95% CI 1.605-34.591, P<0.05). Conclusion:The aEEG monitoring of children with NBM, if abnormal, may indicate severe NBM, which is likely to be transformed into refractory NBM or has a poor prognosis.

Objective Tto analyze the spatial distribution and characteristics of the national AIDS/HIV epidemics from 2009 to 2020 to discover its distribution, aggregation, and hot spots, and provide corresponding suggestions for AIDS prevention and control. Methods Spatial autocorrelation analysis, hot spot analysis, and Kriging interpolation prediction were used to describe, analyze, and predicting the spatial distribution of AIDS epidemics across the country. Results The national AIDS incidence and mortality rate increased yearly, but the growth rate shows a downward tendency with uneven spatial distribution,focusing on the southwest and northwest regions; the average annual incidence rate of AIDS ( Moran's I> 0, P < 0. 01) and the average annual mortality rate (Moran's I> 0, P < 0. 01) of the distribution had a positive global spatial correlation, with Sichuan, Yunnan, Guangxi, Chongqing,Hunan and Guizhou being the areas with ^“high-high^” clusters of AIDS incidence; Sichuan, Yunnan, Guangxi,Hunan,Xinjiang and Guizhou were the areas with ^“high-high^” clusters of average annual mortality. The ^“hot spot^” areas were mainly concentrated in the southwestern part of China, and the ^“cold spot^” areas were mainly concentrated in the eastern coastal and northern parts of China; Kriging interpolation predicted that Xinjiang would be the new hot spot area for future epidemics. Conclusion The spatial distribution of AIDS in China is uneven, showing spatial aggregation, hot spots and cold spots coexist, and the high-risk areas will continue to expand in the future.So the prevention and control work should be carried out in a targeted and localized manner.
