Objective:To explore the abnormal brain metabolic pattern and connectivity in temporal lobe epilepsy (TLE) patients.Methods:18F-FDG PET images of 75 patients diagnosed as drug resistant unilateral TLE from January 2014 to December 2016 in Huashan Hospital of Fudan University were collected retrospectively, including 41 (22 males, 19 females, age (28.4±8.7) years) left TLE (LTLE) and 34 (13 males, 21 females, age (28.5±8.8) years) right TLE (RTLE). Forty-four healthy controls (24 males, 20 females, age (31.2±6.2) years) were also enrolled. The cerebral glucose metabolism in TLE patients and the controls were analyzed with statistical parametric mapping (SPM) 12. The brain connectivity based on glucose metabolism were analyzed with bilateral hippocampus and amygdala as seeds. Permutation test with 1 000 permutations was used to analyze data. Results:Compared to control group, in both LTLE and RTLE groups, hypometabolism was found in affected hippocampus, amygdala, insula and temporal gyrus and hypermetabolism was observed in health hippocampus, parahippocampal gyrus, amygdala, lenticular nucleus and thalamus. In addition, hypometabolism was also found in affected superior/middle frontal gyrus and hypermetabolism was also found in bilateral frontal-orbital gyrus, bilateral cerebellum, affected lenticular nucleus and thalamus in LTLE group. In both TLE groups, affected seeds exhibited increased connectivity with affected superior frontal gyrus, lingual gyrus, fusiform gyrus, superior/middle temporal gyrus and temporal pole (all P<0.05); affected seeds exhibited increased connectivity with health superior frontal gyrus ( P=0.005), lingual gyrus ( P=0.018) and transverse temporal gyrus ( P=0.016) in RTLE group in addition. Besides, affected seeds exhibited decreased connectivity with bilateral default mode network (DMN) (all P<0.05), affected caudate nucleus ( P=0.015) and health thalamus ( P=0.008), in a uniform distribution pattern in LTLE group, and with bilateral cerebral cortex in an irregular distribution pattern in RTLE group (all P<0.05). In LTLE group, health seeds exhibited more increased connections with superior ( P=0.005)/middle frontal gyrus ( P=0.042), health hippocampus ( P=0.038), parahippocampal gyrus ( P=0.019), amygdala ( P=0.038), posterior cingulate gyrus ( P=0.004), and bilateral fusiform gyrusand ( P=0.048) compared with RTLE group; while, in RTLE group, health seeds exhibited more decreased connections with health superior ( P=0.047), inferior frontal gyrus ( P<0.001), orbital frontal gyrus ( P<0.001) and rectus gyrus ( P=0.016) compared with LTLE group. Conclusion:Altered brain glucose metabolism and connectivity pattern are found and will elucidate the underlying metabolic pattern of TLE.

Objective:To analyze the risk factors of bronchopulmonary dysplasia(BPD)in very preterm infants(VPI), and to provide scientific basis for the prevention and treatment of BPD in VPI.Methods:A prospective multicenter study was designed to collect the clinical data of VPI in department of neonatology of 28 hospitals in 7 regions from September 2019 to December 2020.According to the continuous oxygen dependence at 28 days after birth, VPI were divided into non BPD group and BPD group, and the risk factors of BPD in VPI were analyzed.Results:A total of 2 514 cases of VPI including 1 364 cases without BPD and 1 150 cases with BPD were enrolled.The incidence of BPD was 45.7%.The smaller the gestational age and weight, the higher the incidence of BPD( P<0.001). Compared with non BPD group, the average birth age, weight and cesarean section rate in BPD group were lower, and the incidence of male infants, small for gestational age and 5-minute apgar score≤7 were higher( P<0.01). In BPD group, the incidences of neonatal respiratory distress syndrome(NRDS), hemodynamically significant patent ductus arteriosus, retinopathy of prematurity, feeding intolerance, extrauterine growth restriction, grade Ⅲ~Ⅳ intracranial hemorrhage, anemia, early-onset and late-onset sepsis, nosocomial infection, parenteral nutrition-associated cholestasis were higher( P<0.05), the use of pulmonary surfactant(PS), postnatal hormone exposure, anemia and blood transfusion were also higher, and the time of invasive and non-invasive mechanical ventilation, oxygen use and total hospital stay were longer( P<0.001). The time of starting enteral nutrition, cumulative fasting days, days of reaching total enteral nutrition, days of continuous parenteral nutrition, days of reaching 110 kcal/(kg·d) total calorie, days of reaching 110 kcal/(kg·d) oral calorie were longer and the breastfeeding rate was lower in BPD group than those in non BPD group( P<0.001). The cumulative doses of amino acid and fat emulsion during the first week of hospitalization were higher in BPD group( P<0.001). Multivariate Logistic regression analysis showed that NRDS, invasive mechanical ventilation, age of reaching total enteral nutrition, anemia and blood transfusion were the independent risk factors for BPD in VPI, and older gestational age was the protective factor for BPD. Conclusion:Strengthening perinatal management, avoiding premature delivery and severe NRDS, shortening the time of invasive mechanical ventilation, paying attention to enteral nutrition management, reaching whole intestinal feeding as soon as possible, and strictly mastering the indications of blood transfusion are very important to reduce the incidence of BPD in VPI.

Rubus corchorifolius(Shanmei or mountain berry,2n=14)is widely distributed in China,and its fruits possess high nutritional and medicinal values.Here,we reported a high-quality chromosome-scale genome assembly of Shanmei,with contig size of 215.69 Mb and 26,696 genes.Genome comparison among Rosaceae species showed that Shanmei and Fupenzi(Rubus chingii Hu)were most closely related,followed by blackberry(Rubus occidentalis),and that environmental adaptation-related genes were expanded in the Shanmei genome.Further resequenc-ing of 101 samples of Shanmei collected from four regions in the provinces of Yunnan,Hunan,Jiangxi,and Sichuan in China revealed that among these samples,the Hunan population of Shanmei possessed the highest diversity and represented the more ancestral population.Moreover,the Yunnan population underwent strong selection based on the nucleotide diversity,linkage dise-quilibrium,and historical effective population size analyses.Furthermore,genes from candidate genomic regions that showed strong divergence were significantly enriched in the flavonoid biosyn-thesis and plant hormone signal transduction pathways,indicating the genetic basis of adaptation of Shanmei to the local environment.The high-quality assembled genome and the variome dataset of Shanmei provide valuable resources for breeding applications and for elucidating the genome evo-lution and ecological adaptation of Rubus species.

Objective:To establish a program for the prevention and management of parastomal hernia in patients with ostomy.Methods:Based on literature analysis and clinical needs, combined with the individual and family self-management theory (IFSMT), a preliminary plan for prevention and management of parastomal hernia was developed with the framework of case management model. Sixteen experts were selected for two rounds of Delphi expert consultations to analyze and screen indicators at all levels to calculate the expert′s positive coefficient, authority coefficient and coordination coefficient to analyze the credibility of expert consultation results.Results:The effective recovery rates of the two rounds of expert letter inquiries were 88.89% and 100.00%, the authoritative coefficients were 0.825 and 0.844, and the two rounds of Kendall′s W values were 0.221 and 0.269, which were statistically significant( P<0.01). The concentration of indicators is high. Finally, a programe for parastomal hernia prevention and management based on the self-management theory of individual and family consisting of 6 first-level indicators,16 second-level indicators and 42 third-level indicators was obtained. Conclusion:The programe for prevention and management of parastomal hernia based on individual and family self-management theory has high reliability and scientificity, and can provide a basis for the study of parastomal hernia prevention and management.

Objective:To investigate the association of blood oxidative stress level with hypertriglyceridemia in the elderly aged 65 years and older in China.Methods:A total of 2 393 participants aged 65 years and older were recruited in 9 longevity areas from Heathy Aging and Biomarkers Cohort Study, during 2017 to 2018. Information on demographics characteristic, life style and health status were collected by questionnaire and physical examination, and venous blood was collected to detect the levels of blood oxidative stress and hypertriglyceridemia. The linear or non-linear association between oxidative stress and hypertriglyceridemia was described by restrictive cubic splines (RCS) fitting multiple linear regression model. The generalized linear mixed effect model was conducted to assess the association between oxidative stress and hypertriglyceridemia.Results:A total of 2 393 participants, mean age was 84.6 years, the youngest was 65 and the oldest was 112, the male was 47.9%(1 145/2 393), the triglyceride level was (1.4±0.8) mmol/L. The hypertriglyceridemia detection rate was 9.99%(239/2 393). The results of multiple linear regression model with restrictive cubic spline fitting showed that MDA level was linear association with triglyceride level; SOD level was nonlinear association with triglyceride level. MDA level had significantly association with hypertriglyceridemia, and the corresponding OR value was 1.063 (95% CI: 1.046,1.081) with 1 nmol/ml increment of blood MDA; SOD level had significantly association with hypertriglyceridemia, and the corresponding OR value was 0.986(95% CI: 0.983,0.989) with 1 U/ml increment of blood SOD. Conclusion:Among the elderly aged 65 and older in 9 longevity areas in China, MDA and SOD levels were associated with the risk of hypertriglyceridemia.

Ancestry composition of populations and individuals has been extensively investigated in recent years due to advances in the genotyping and sequencing technologies. As the number of populations and individuals used for ancestry inference increases remarkably, say more than 100 populations or 1000 individuals, it is usually challenging to present the ancestry composition in a traditional way using a rectangular graph. To address this issue, we developed a program, AncestryPainter, which can illustrate the ancestry composition of populations and individuals with a rounded and nice-looking graph to save space. Individuals are depicted as length-fixed bars partitioned into colored segments representing different ancestries, and the population of interest can be highlighted as a pie chart in the center of the circle plot. In addition, AncestryPainter can also be applied to display personal ancestry in a way similar to that for displaying population ancestry. AncestryPainter is publicly available at http://www.picb.ac.cn/PGG/resource.php.

Objective To investigate the sleep quality of patients with systemic lupus erythematosus (SLE) and to analyze its influencing factors. Methods A total of 156 patients with SLE who were treated in the Rheumatology Department of the First Affiliated Hospital of Zhengzhou University from October 2016 to January 2017 were selected as the research objects by convenience sampling method. All the participants were investigated by general information questionnaire, Pittsburgh sleep quality index (PSQI) scale and systemic lupus erythematosus disease activity index (SLEDAI). The influencing factors of patients' sleep quality was analyzed by single factor analysis and multiple linear regression analysis. Results The score of PSQI scale of SLE patients was (10.04±5.83). It was reported that 62.23% of patients had poor sleep quality. The main reason for night sleep disturbance were easy to wake up at night, night frequent urination and sensory heat. Single factor analysis showed that there was significant difference in total sleep quality among SLE patients with different age, education level, number of hospitalization, course of the disease, daily average dose of glucocorticoid and disease activity index (P< 0.05). Multiple linear regression analysis showed that age, course of the disease, daily average dose of glucocorticoid and disease activity index were the influencing factors of SLE patients' sleep quality (P<0.01). Conclusions The results indicate that sleep quality of SLE patients is influenced by age, course of disease, daily average dose of glucocorticoids and disease activity index. Medical staff should pay attention to patients' sleep problems and give sleep nursing interventions on the basis of treatment in order to improve the sleep quality and life quality of SLE patients.

Objective To translate the English version of Safety Attitudes Questionnaire (SAQ) into Chinese,and to test the reliability and validity of the Chinese version of SAQ. Methods The SAQ was developed into Chinese version through translation, back-translation and cross-culture adaption.

The correlations between the items and the full scale, the dimensions and the full scale separately ranged from 0.32 to 0.64 and 0.50 to 0.81 (P<0.01). The confirmatory factor analysis resulted in a good model fit for the six dimensions and the full construct, the goodness-of-fit index was 0.96, Tucker-Lewis index was 0.93, comparative fit index was 0.95, and root mean square error of approximation was 0.06. The Cronbach alpha coefficient for the scale was 0.913 and for the six dimensions were 0.565, 0.655, 0.825, 0.804, 0.880, 0.725 separately, the test-retest reliability coefficient was 0.934. Conclusions The Chinese version of SAQ is a valid and reliable tool to assess the safety culture of first-line nurse managers in Chinese hospitals.

OBJECTIVETo observe the clinical efficacy of deep acupuncture at Lianquan (CV 23) and Yifeng (TE 17) combined with swallowing training for post-stroke dysphagia.

METHODSSixty cases of post-stroke dys phagia were randomly divided into an observation group and a control group, 30 cases in each one. Patients in the observation group, based on the regular acupuncture treatment, were treated with deep acupuncture at Lianquan (CV 23) and Yifeng (TE 17), once a day, 30 min per treatment; also swallowing training was combined, twice a day, 20 min per treatment. Patients in the control group were treated with swallowing training. All the patients were treated with regular treatment of stroke. Six days of treatment were taken as one session, and totally 3 sessions were given with an interval of one day between sessions. The video fluoroscopic swallowing study (VFSS) dysphagia evaluation scale and Watian water swallow test (WWST) were evaluated before and after treatment also the clinical efficacy and the recovery time of two groups were compared.

RESULTSAfter treatment, the VFSS score in the observation group was significantly superior to that in the control group (P < 0.01); the WWST in the observation group was significantly superior to that in the control group (P < 0.01). The cured rate was 70.0% (21/30) in the observation group, which was significantly superior to 43.3% (13/30) in the control group (P < 0.01); the total effective rate was 86.7% (26/30) in the observation group, which was significantly superior to 66.7% (20/30) in the control group (both P < 0.01). The clinical recovery time in the observation group was significantly shorter than that in the control group (P < 0.01).

CONCLUSIONDeep acupuncture at Lianquan (CV 23) and Yifeng (TE 17) combined with swallowing training could effectively improve post-stroke swallow function.
