To explore the correlation between nucleated red blood cell (NRBC) count and perinatal asphyxia in neonates.Full-term newborns born from May 2011 to November 2012 were recruited and divided into perinatal asphyxia (n =40) and normal (n =30) groups.Apgar score was recorded immediately at delivery.The umbilical arterial blood was also collected into anticoagulant-treated tube and NRBC was counted by Japan OlympusCX41 biological microscope.NRBC count for perinatal asphyxia group [(10.70 ± 2.61)/100 WBC] was significant higher than that for normal group [(2.67 ± 0.35)/100 WBC].A statistically significant negative correlation existed between NRBC and umbilical arterial blood pH,Apgar score at 1 min,BE value (r =-0.802,P ＜ 0.05 ; r =-0.639,P ＜ 0.05 ; r =-0.566,P ＜ 0.05).Associated with perinatal asphyxia in neonates,NRBC may be used as a simple index for assessing the severity of neonatal perinatal asphyxia.

Objective To study the predictive values of the general movements (GMs) assessment in writhing stage for motor development outcomes in infants with severe neonatal jaundice.Method From December of 2012 to December of 2017,infants with severe neonatal jaundice (serum bilirubin reaching the corresponding level of exchange transfusion according to the reference nomogram) in our hospital were enrolled in the study.Inclusion criteria included corrected gestational age of 37 to 48 weeks,serum bilirubin level below phototherapy intervention value after treatment and general and detailed assessment were carried out in writhing stage when the infant was stable.The patients were regularly followed-up until one-year-old to evaluate the predictive values.Result A total of 241 patients with severe neonatal jaundice were enrolled in the study,including 153 males (63.5％) and 88 females (36.5％),with gestational age between 35 and 42 weeks.The mean gestational age was (37.9± 1.8) weeks,the average birth weight was (3 057±480) g,and the mean serum bilirubin value was (458.9± 119.1) μmol/L.The general evaluation of the GMs was normal in 15 cases (6.2％),and abnormal in 226 cases (93.8％) with 217 cases (90.0％) were poor repertoire (PR) and 9 cases (3.7％) were cramped-synchronized (CS).The predictive values of abnormal GMs for abnormal motor development outcomes were as following:sensitivity 100％,specificity 7.6％,negative predictive value(NPV) 100％.The predictive values of CS for cerebral palsy were as following:sensitivity 22.2％,specificity 97.8％,NPV 94.0％.Detailed evaluation of 241 subjects showed that 13 items had statistically significant differences in the prediction of cerebral palsy (P＜0.05),and 18 items in the prediction of abnormal motor development (P＜0.05).Conclusion The CS pattern and detailed assessment of GMs in the writhing stage may be correlated with the outcomes of motor development in infants with severe neonatal jaundice until one-year-old.

Objective:To study the predictive values of the general movements (GMs) assessment combined total bilirubin for motor development outcomes in infants with severe neonatal jaundice.Methods:From June of 2014 to June of 2019, infants with severe neonatal jaundice in Chenzhou First People′s Hospital were enrolled in the study. Inclusion criteria included , the serum total bilirubin was measured at the time of admission, corrected gestational age of 37 to 48 weeks. General assessment were carried out when the infant was stable. The patients were regularly followed-up until the age of 12months to evaluate the predictive values.Results:A total of 204 patients with severe neonatal jaundice were enrolled in the study, with mean serum total bilirubin value (485.4±109.6)μmol/L. They were divided into two groups according to the outcome of motor development. The total bilirubin value, the proportion of abnormal GMs and dangerous total bilirubin level in the abnormal group were significantly higher than those in the normal group (all P<0.05). 13 cases (6.4%) were normal in the torsion stage of GMs; 191 cases (93.6%) were abnormal, including 164 cases (85.9%) of poor repertoire (PR) and 27 cases (14.1%) of cramped-synchronized (CS). Abnormal GMs and total bilirubin were the risk factors of abnormal motor development ( OR=4.651, 1.017, P<0.05). The predictive values of abnormal GMs for abnormal motor development outcomes were as following: sensitivity 100%, specificity 8.4%, negative predictive value (NPV) 100%. The predictive values of CS for cerebral palsy were as following: sensitivity 63.2%, specificity 97.8%, NPV 96.0%. Receiver operating characteristic (ROC) curve showed that the area under the curve predicted by GMs and total bilirubin was 0.765 and 0.757, respectively. The area under the curve of motor dysplasia predicted by combining the two was 0.854. Conclusions:The evaluation of general movement assessment combined total bilirubin has certain clinical predictive value for the outcomes of motor development in infants with severe neonatal jaundice.

Objective:To analyze the influenza vaccination status of chronic disease management patients in Qingpu district of Shanghai and the vaccination characteristics of different characteristic populations, so as to provide scientific basis for improving the influenza vaccination rate of chronic disease patients in the community.Methods:By comparing the data of Shanghai chronic disease management information system, immunization planning information system and medical association platform, 89 453 subjects who met the inclusion and exclusion criteria in Qingpu district were selected as the research objects. The vaccination coverage rate of the study subjects was calculated according to gender, age group, urban and rural distribution, occupation, chronic disease type and quantity, and the vaccination coverage rate of different subgroups was compared to analyze the influencing factors of vaccination coverage rate.Results:Most of the 89 453 patients with chronic diseases were 60 years old and above (71.93%). Patients with hypertension, diabetes, chronic obstructive pulmoriary disease (COPD) and three chronic diseases accounted for 87.12%, 28.67%, 8.71% and 1.83%, respectively. Influenza vaccination coverage in the 2016/2017 flu season was low, at 0.32%. Influenza vaccination coverage rate of women (0.37%) was higher than that of men (0.27%), which was 1.41 times respectively(95% CI: 1.16, 1.72) that of men patients. The coverage rate of influenza vaccination for the 70-79 year-old group was the highest (0.74%), which was 1.74 times respectively(95% CI: 1.39, 2.19) that of 60-69 year-old patients. The vaccination coverage rate of government departments and institutions was the highest (1.14%), which was 12.58 times respectively(95% CI: 4.52, 34.99) that of retirees. The vaccination rate of COPD patients (3.68%) was 2.50 times (95% CI: 1.66, 3.77) higher than that of patients without COPD.Conclusions:Influenza vaccination rate for chronic disease management patients in Qingpu district of Shanghai is low. Gender, occupation, age and types of chronic diseases are the influencing factors. Patients with chronic disease management should be included in the priority vaccination targets for influenza vaccines, and vaccination intervention for occupational chronic diseases such as non-retired agriculture and forestry patients, especially male patients, should be strengthened to improve influenza vaccination coverage rate.

Objective To evaluate the efficacy and safety of ozone injection therapy for lumbar disc hemiation(LDH).Methods A computerized retrieval of academic papers concerning the randomized controlled trial(RCT)on ozone injection therapy for LDH from the databases of Embase,PubMed,Cochrane library and Web of science was conducted.The retrieval time period was from the establishment of the database to February 2023.The literature retrieval,screening,and data extraction were independently performed by two researchers.Cochrane bias risk assessment tool was used to assess the quality of the included literature.Stata 17.0 software was used to make meta-analysis.Results A total of 9 RCTs including 702 patients were finally included in this study.The results of meta-analysis showed that compared with radiofrequency thermocoagulation,percutaneous rotation and other treatments for LDH,the combination use of ozone injection could signifiicantly improve the effective rate based on Macnab efficacy evaluation criteria(RR=1.097,95％CI:1.038～1.159,P=0.001)and the excellent rate(RR=1.185～95％CI:1.074～1.309,P=0.001),and decrease the visual analog scale(VAS)pain score(WMD=-0.810～95％CI:-1.205～-0.414,P=0.000),and the differences in the above indexes were statistically significant.Conclusion Compared with the simple use of radiofrequency thermocoagulation,percutaneous rotation,and other treatment for LDH,the combination use of ozone injection therapy can significantly improve the effective rate and excellent rate based on Macnab efficacy evaluation criteria,decrease VAS score,with a high clinical safety.Limited by the quantity and quality of the original studies included in this study,the above conclusions need to be further verified by multi-center,large-sample and high-quality studies.

Objective To observe the impact of age and menstrual status on semi-quantitative parameters of breast dynamic enhanced MRI(DCE-MRI)in healthy adult women.Methods A total of 283 adult females who underwent MR examinations due to suspected breast mass or breast discomfort but no breast tumor was detected after 1 year's clinical follow-up were retrospectively collected.Meanwhile,49 healthy adult female subjects in the menstrual period(menstruating subgroup)were prospectively recruited.All the above 332 subjects were divided into low age group(n=107),middle age group(n=114)and high age group(n=111)according to age,while into postmenopausal group(n=112)and premenopausal group(n=220,including 49 in menstruating subgroup,77 in proliferating subgroup and 94 in secreting subgroup).DCE-MRI semi-quantitative parameters,including maximum enhancement rate(ERmax)and maximum slope of increasing(Slopemax)were compared among different groups and subgroups,and the variations were observed.Results Significant differences of ERmax and Slopemax were found between high and low age groups(both P＜0.05),while no significant difference of ERmax and Slopemax was found between middle and low age group,nor between middle and high age group(all P＞0.05).Both ERmax and Slopemax in postmenopausal group were lower than those in premenopausal group(both P＜0.05),while no significant difference of DCE-MRI semi-quantitative parameters was found among different menstrual cycle subgroups(all P＞0.05).The coefficient of variance(CV)of normal breast ERmax in low,middle and high age groups was 56.20％,44.02％and 50.97％,respectively,of Slopemax was 54.74％,81.78％and 76.93％,respectively.CV of normal breast ERmax was 50.12％and 46.02％in postmenopausal and premenopausal groups,respectively,while CV of Slopemax was 72.84％and 62.04％,respectively.Among different subgroups,CV of ERmax and Slopemax in proliferative period were both the largest(61.39％,82.54％),which in menstrual period were both the smallest(33.99％,42.33％).Conclusion Semi-quantitative parameters of breast DCE-MRI were different among healthy women of different age and menstrual status,and the individual variations were large.

ObjectiveTo understand the incidence and change trend of thyroid cancer in Qingpu District， Shanghai from 2007 to 2016， and to provide a reference for formulating relevant prevention and treatment strategies. MethodsThe incidence data of thyroid cancer among residents in Qingpu District from 2007 to 2016 were collected using the Shanghai Malignant Tumor Registration System， and the crude incidence rate was calculated for different gender and age groups. The age-standardized incidence rate was calculated using the world standard population， and the annual percentage change （APC） was calculated using Joinpoint software to analyze the time trend of the incidence of thyroid cancer. ResultsThe incidence of thyroid cancer changed from 8.97/10⁵ in 2007 to 52.02/10⁵ in 2016， with an increase of 479.93% （APC=23.60， P<0.05）. The standardized incidence rate of thyroid cancer in men and women was 11.21/10⁵ and 32.11/10⁵， respectively， Male to female incidence ratio was 1∶3. Thyroid cancer in Qingpu District was mainly concentrated in the 25‒64 age group， accounting for 88.03% of the total incidence. ConclusionFrom 2007 to 2016， the incidence of thyroid cancer in Qingpu District， Shanghai has a significant upward trend. The age of high incidence tends to be younger and the incidence of women is significantly higher than that of men. Corresponding prevention and treatment measures should be formulated in consideration of the discovered incidence characteristics.

【Objective】 To explore the relationship of graduate students’ psychological stress and perceived stress with their mental health, and analyze the mediating effect of perceived stress. 【Methods】 We investigated 705 graduate students by Chinese College Student Mental Health Scale (CCSMHS), Chinese College Student Psychological Stress Scale (CCSPSS), and Perceived Stress Scale-10 (PSS). Correlation and structural equation model analysis was made. 【Results】 The graduate students’ psychological stress and perceived stress had significant correlation with their mental health. SEM analysis showed that perceived stress served as a partial mediation variable between psychological stress and mental health. Psychological stress had direct effects (0.216) for mental health and indirect effects (0.126) through perceived stress. 【Conclusion】 Graduate students’ psychological stress can influence their mental health directly, and can also reduce mental health level by increasing perceived stress. Perceived stress has partial mediating effect between psychological stress and mental health.

Objective To understand the characteristics and temporal trends of stroke incidence in the household population of Shanghai's Qingpu District and to provide a basis for the development of comprehensive prevention and control strategies. Methods The stroke case database for Qingpu District from 2017-2022 was obtained from the Shanghai Stroke and Acute Myocardial Infarction Registry and Reporting Information System. The average age of onset, incidence rate, standardised incidence rate, and constitutive ratio were calculated. Independent samples t-tests were used for comparisons between groups, 2-tests and 2-trend tests for comparisons of rates, and the Joinpoint regression model for calculating the annual percentage change (APC) to analyse the temporal trend of rates. Results Between 2017 and 2022, the average age of stroke onset in the household population of Shanghai's Qingpu District was 73.69±11.60 years. The average annual incidence rate was 556.62/100 000, with an average annual standardised incidence rate of 333.76/100000. There was an increasing trend in the incidence and standardised incidence of stroke in males (APC=7.06%, t=3.44, P=0.03, APC=5.32%, t=3.04, P=0.04). The incidence of stroke increases with age, with cases mainly concentrated in those aged 65 years and above, accounting for 79.47%. Ischemic stroke dominates the stroke typology, accounting for 91.08% of cases, while the incidence of hemorrhagic stroke shows an increasing trend (APC=4.64%, t=4.59, P=0.01). Conclusion The occurrence of stroke in the general population of Shanghai’s Qingpu District is concerning. The study indicates that males, individuals aged 65 years and above, and ischaemic stroke are significant factors that require attention for stroke prevention and control.
