Objective:
To analyze the death among children under 5 years of age in Huzhou City, Zhejiang Province from 2012 and 2021, so as to provide insights into reduction of mortality among children.
Methods:
The mortality surveillance data among children under 5 years of age in Huzhou City from 2012 to 2021 were collected from Children Death Report Cards and Surveillance Report among Children under 5 Years of Age, including gender, place of residence, date of death and death diagnosis. The trends in mortality and cause of death were analyzed among children under 5 years of age in Huzhou City from 2012 to 2021.
Results:
A total of 1 262 deaths occurred among children under 5 years of age in Huzhou City from 2012 to 2021, with mean annual mortality of 4.39‰, and the mortality appeared a tendency towards a decline (χ2trend=132.695, P<0.001). A total of 899 infants died, with mean annual mortality of 3.13‰, and 363 children at ages of 1 to <5 years died, with mean annual mortality of 1.26‰. The mortality appeared a tendency towards a decline among both infants (χ2trend=117.778, P<0.001) and children at ages of 1 to <5 years (χ2trend=19.201, P<0.001). A total of 724 local children died, with mean annual mortality of 3.33‰, and there were 538 deaths among floating children, with mean annual mortality of 7.65‰. The mortality appeared a tendency towards a decline among both local (χ2trend=43.728, P<0.001) and floating children (χ2trend=94.038, P<0.001). The five most common causes of death included preterm birth or low birth weight (207 deaths, 16.40%), drowning (155 deaths, 12.28%), accidental asphyxia (138 deaths, 10.94%), other congenital abnormalities (126 deaths, 9.98%), and congenital heart diseases (113 deaths, 8.95%).
Conclusions
The mortality appeared a tendency towards a decline among children under 5 years of age in Huzhou City from 2012 to 2021, and preterm birth or low birth weight was the predominant cause of death.

Objective To explore the correlation between heart rate variability ( HRV ) and multiple system atrophy( MSA) .Methods HRV was performed in 34 MSA patients and 32 healthy controls.The parameters of HRV study was compared, parameters studied included time domain and frequency domain.Single factor analysis andreceiver operating characteristic ( ROC ) curves were used to analyze the detection of parameters of HRV. ResultsThe HRV of MSA showed significant decreased from the health controls: root mean square successive difference of intervals (rMSSD) [(51.6 ±29.4)ms vs (70.1 ±34.1)ms,P=0.023],percentage of interval differences of successive N-N intervals greater than 50 ms(pNN50%) [ 4.2% (1.8%,9.5%) vs 9.6%(5.1%, 16.2%),P=0.005], coefficient of variation(CV) [(0.06 ±0.01) vs(0.08 ±0.02),P=0.005],very low frequency(VLF) [1003.4(586.5,1702.9)ms2vs1825.5(1407.2,2670.1)ms2,P=0.000],lowfrequency(LF) [162.9(90.6,337.4) ms2 vs 375.5(210.4,559.5) ms2,P=0.001], high frequency(HF) [164.9(77.5,470.7) ms2 vs 349.1(209.7,738.5)ms2,P=0.005].The areas under ROC in patients with MSA for VLF was 0.703(S=0.053), while the areas for CV, LF, HF and pNN50%were 0.667(S=0.054), 0.660 (S=0.055), 0.650( S=0.055) and 0.640( S=0.055) ,the results all have statistical significance(all P<0.05).The cutoff value of VLF for diagnosing MSA in the early stage was 1240.85, the sensitivity and specificity were 86.7 and 55.4(95%CI:0.599-0.807,P=0.002) .Conclusion MSA has sympathetic and vagus nerve involvement at the early stage disease, resulting dysfunction of cardiovascular autonomic system,VLF may have high drgree of assessing accuracy of its dysfunction.

Objective To analyze the clinical features and causes of benign paroxysmal positional vertigo(BPPV).Methods The clinical data of 521 patients with BPPV were collected.The percentage of patients with BPPV in all the outpatients with dizziness and vertigo,the clinical characteristics of BPPV,and the prevalence of comorbidity with migraine were analyzed.Results BPPV accounted for 35.7% of patients with vertigo and 12.1% of patients with dizziness.Among the 521 patients with BPPV,158(30.3%)were male and 363(69.7%)were female,with an average age of(57.5?12.8)years old(20 to 93 years old).Right semicircular canals were involved in 323 cases(62.0%),and left semicircular canals in 187 cases(35.9%).The latency period of nystagmus of vertical canals was(3.22?2.37)s,and time of persistence was(8.31?7.98)s.The latency period of nystagmus of horizontal canals was(2.33?1.50)s,and the time of persistence was(14.77?11.40)s.There were significant differences in the latency period of nystagmus and time of persistence between the vertical and horizontal canals(P=0.001 and P=0.000).Fifteen patients(2.9%)had a history of head trauma and 39(7.5%)were complicated with migraine.Conclusion BPPV is prevalent in patients with dizziness and vertigo,and misdiagnosis and missed diagnosis should be avoided.

Objective To explore the effect of chronic compound stress on serum adiponectin level and AdipoR2 expression in rats.Methods Forty male Sprague-Dawley rats were randomly divided into two groups:the stress group underwent chronic compound stress and the control group was fed normally.After 8 weeks of stress or feeding,the serum adiponectin,blood glucose ,insulin resistance and HbA1 C,HDL-C,LDL-C,triglyceride and total cholesterol were measured.Results ①After 8 weeks of stress,the score of open-field behaviors and 24-h urocortisol were significantly different between the stress and control groups (32.0 ± 8.6 vs.52.0 ± 12.7,5.8 ± 0.4 vs.(5.3 ±0.1 ) ng/L,repectively; P <0.05 or 0.01 ) ;②After 8 weeks of stress,the adiponectin,total cholesterol ,triglyceride,HDL-C,InIR and HbA1 C were significantly different between the two groups (P < 0.05 or 0.01 ) ;③After 8 weeks of stress,there were significant difference on the expression of AdipoR2mRNA and protein between the two groups (P <0.01 ) ,with the expression of AdipoR2mRNA of 0.67 ±0.04 and 1.00 ±0.11 and the expression of protein of 0.73±0.02 and 1.00 ± 0.04 in the stress and control group,respectively.Adiponectin was negatively related with HbA1 C,LDL-C and IR ( r = - 0.26,- 0.88 and - 0.37,P < 0.05 or 0.01 ),and positively related with HDL-C ( r =0.78 ,P <0.01 ).Conclusions In rats,chronic compound stress decreases the level of serum adiponectin and the expression of AdipoR2 in liver.

In order to establish a method for the determination of the sterols of the oil in the freeze-dried acai (Euterpe oleracea Mart.) and to evaluate its antioxidant activities, a saponification/extraction procedure and high performance liquid chromatography (HPLC) analysis method were developed and validated for the analysis of phytosterols in PEE (Petroleum ether extract). Separation was achieved on a Purosper STAR LP C18 column with a binary, gradient solvent system of acetonitrile and isopropanol. Evaporative light scattering detection (ELSD) was used to quantify β-sitosterol and the total sterols. Peak identification was verified by retention times and spikes with external standards. Standard curves were constructed (r = 0.999 2) to allow for sample quantification. Recovery of the saponification and extraction was demonstrated via analysis of spiked samples. The highest content of total sterols is β-sitosterol. The antioxidant activities of the extracts were evaluated using the total oxyradical scavenging capacity assay (TOSC assay). The result showed that the PEE exhibited significant antioxidant properties, sample concentration and the antioxidant capacity had a certain relevance.

Objective To understand the progress in schistosomiasis resoareh over the last l0 years through a biblimetrie approaeh.Methods The literature was searched in Web of Science citation database (1998-2008)by using the following terms: schistosomiasis* or schistosoma or schistosome. The searching results were analyzed by the Derwent Analytics software concerning the article numbers and the total citations by countries,institutes and authors, and journal distribution, in an effort to discover schistosomiasis research progress in and outside China. Results The annual number of schistosomiasis articles published in Web of Science had little change from 1998 to 2008.The US phyed a leading role in the schistosomiasis research in the world.China had made a great progress in schistosomiasis research in the past years.but Was still lagging behind developed countries.The vaccine and drug development,the immune mechanisms resulting in morbidity were the focuses of schistosomiasis research in the world.Meanwhile.the transcriptome and proteome of Schistosoma japonicum,schistosomiasis vaccines and drugs,spatial epidemiology Were the focuses of research in China.Conclusion The research of schistosomiasis in China has been progressing rapidly,but is still lagging behind its international peers.
