Objective: To evaluate the effect of remote health interventions on self-management of hypertension. Methods: We systematically searched the literature for studies published in English in PubMed, Embase, Web of Science, China National Knowledge Infrastructure (CNKI), and Cochrane Central Register of Controlled Trials. The database was used to search for relevant studies with full text and evaluate the remote health interventions for hypertension self-management versus usual care for hypertension. RevMan 5.4 was used for data analysis. Results: A total of 19 studies eventually met our inclusion criteria. The results showed that the remote health interventions group could significantly reduce the levels of SBP (MD=5.67, 95% CI=4.12-7.22, p<.001) and DBP (MD=1.88, 95% CI=1.16- 2.60, p<.001), compared with usual care group, it also significantly improving the patient's quality of life (SMD=0.84, 95% CI=0.32- 1.37, p=.002), reduce waist circumference (MD=2.39, 95% CI=0.35-4.44, p=.020) and BMI (MD=0.49, 95% CI=0.06-0.91, p=.020), and significantly increasing the physical activity of patients (SMD=0.19, 95% CI=0.06- 0.31, p=.004). No obvious publication bias was found in this meta-analysis. Conclusion This study showed that remote health interventions for self-management can significantly improve patients’ quality of life with hypertension and better BP control than usual care. Further studies could be assess the long-term clinical effectiveness and economic evaluation of remote health interventions for self-management.

Objective To analyze the correlation between T lymphocyte subsets,neutrophil/lymphocyte ratio(NLR),procalcitonin(PCT)and the severity of sepsis.Methods A prospective research method was adopted.A total of 78 sepsis patients admitted to the department of intensive care medicine of Zibo Central Hospital from January 2021 to December 2022 were selected as the research subjects.Patients were divided into a septic shock group(37 cases)and a sepsis group(41 cases)based on the severity of their condition,with 40 healthy examinees from our hospital as the healthy control group.Using flow cytometry to measure the levels of CD4+ T lymphocytes count(CD4+ T)and CD8+ T lymphocytes count(CD8+ T)in three groups of subjects,calculate the CD4+ T/CD8+ T lymphocyte ratio(CD4+ T/CD8+ T)and NLR.The levels of PCT and interleukin-6(IL-6)were measured using electrochemiluminescence immunoassay,and the levels of C-reactive protein(CRP)were measured using immunoassay turbidimetry.Acute physiology and chronic health evaluationⅡ(APACHEⅡ)score within 24 hours was recorded for the two groups of patients,and the differences in lymphocyte subsets and various inflammatory indicators were compared between the groups.Pearson correlation analysis was used to analyze the correlation between various indicators and APACHEⅡscore.Results The CD4+ T,CD8+ T,and CD4+T/CD8+T levels in the septic shock and sepsis groups were significantly lower than those in the healthy control group[CD4+ T(×106/L):168.27±76.68,266.08±131.57 vs.789.60±173.78,CD8+ T(×106/L):156.50±68.37,205.81±75.60 vs.636.42±90.59,CD4+ T/CD8+ T:1.09±0.39,1.27±0.34 vs.1.44±0.38,all P<0.01],NLR,PCT,CRP and IL-6 were significantly higher than those in the healthy control group[NLR:25.85±11.62,15.94±8.72 vs.2.68±1.31,PCT(μg/L):21.82±15.28,9.09±4.96 vs.0.13±0.10,CRP(mg/L):158.65±62.33,106.97±51.49 vs.6.48±2.08,IL-6(ng/L):1 344.64±899.21,245.31±176.99 vs.3.25±1.83,all P<0.01].The APACHEⅡscore in the septic shock group was significantly higher than that in the sepsis group(32.00±1.00 vs.22.01±1.09,P<0.05).Correlation analysis showed that the levels of CD4+ T,CD8+ T,CD4+ T/CD8+ T in two groups of sepsis patients were negatively correlated with the APACHEⅡscore(r values were-0.571,-0.506,and-0.555,respectively,all P<0.01),while the levels of NLR,PCT,CRP,and IL-6 were positively correlated with the APACHEⅡscore(r values were 0.711,0.709,0.777,and 0.707,respectively,all P<0.01).Conclusions As the levels of T lymphocyte subsets decrease,inflammatory indicators like NLR and PCT rise,indicating a more severe sepsis condition.Therefore,T lymphocyte subsets and levels of various inflammatory indicators can serve as markers for evaluating the severity of sepsis.

Objective:To study the stability and morphological changes of the convexity sulci in normal fetuses between 20 and 32 weeks, and to explore the simplified grade for evaluating the convexity sulci development and analyzing its clinical significance.Methods:This study was a cross-sectional analysis. A total of 551 cases of normal singleton pregnancies between 20 and 32 weeks of gestation were retrospectively collected, who underwent routine ultrasound examinations at Shenzhen Maternity and Child Healthcare Hospital from September 2019 to June 2022. The display of the far-field convexity sulci on the transcalvarial axial plane was observed as 0 for not displayed and 1 for displayed.Further, based on the morphology and number of convexity sulci, they were classified into five grades: no sulcus displayed (grade 0), one sulcus (grade 1), two sulci (grade 2), three sulci (grade 3), and four or more sulci (grade 4). The gestational age at examination and pregnancy outcomes were recorded. The distribution characteristics of gestational weeks for each grade of the convexity sulci were analyzed, and the gestational week distribution of the left and right convexity sulci was compared to analyze bilateral symmetry. The Weighted Kappa coefficient was used to analyze inter-observer and intra-observer consistency, and curve regression analysis was employed to establish a model for predicting grade based on gestational weeks.Results:Before 25 weeks of gestation, the convexity of the fetal cranial vertex was completely smooth.The central sulcus consistently appeared after 26 weeks, while the superior frontal sulcus, intraparietal sulcus, postcentral sulcus, and precentral sulcus consistently appeared between 28 and 31 weeks. Among these, the superior frontal sulcus had a lower display rate before 29 weeks. By 32 weeks, all convexity sulci of the cranial vertex should be visible. Three hundred and eleven fetuses were graded for the left, and 240 fetuses were graded for the right. The developmental grade of the convexity sulci increased from Grade 0 to Grade 4 as the gestational age progressed. Grade 0 appeared between 20-26 weeks, grade 1 between 25-28 weeks, grade 2 between 26-28 weeks, grade 3 between 27-30 weeks, and grade 4 between 27-32 weeks. The distribution of grade did not differ significantly between the left and right sides of grade 0, 1, 3 and 4 (all P>0.05), while there was a significant difference in the distribution of gestational age between the convexity sulci of grade 2 ( P<0.05). The Weighted Kappa coefficients for intra-observer and inter-observer consistency were 0.94 and 0.86, respectively, indicating strong consistency. Conclusions:The simplified grade for assessing the development of convexity sulci in normal fetuses on the transcalvarial axial plane via prenatal ultrasound can provide a preliminary evaluation of the maturation of convexity sulci in fetuses between 20 and 32 weeks of gestation.

Objective:To explore significance of eosinophil and eosinophil/lymphocyte ratio(ELR)in predicting allergic asth-ma in children in different seasons.Methods:Retrospective analysis of children with asthma who visited pediatric respiratory depart-ment outpatient clinic and ward of Shandong Provincial Hospital Affiliated to Shandong First Medical University from January 2021 to December 2021,whose allergen specific IgE(sIgE)and peripheral blood cell analysis were complete.sIgE≥0.35 kUA/L were included in allergic asthma group,sIgE<0.35 kUA/L and total allergen IgE<60 kUA/L were included in non-allergic asthma group.General data and changes in peripheral blood cells of two groups were analyzed.Results:There were 1 378 qualified subjeats,including 999(72.5%)in allergic asthma group and 379(27.5%)in non-allergic asthma group.Number of visits in allergic asthma group varied seasonally,with the most in autumn.Peripheral blood lymphocyte count(LYMPH),eosinophil count(EOS)and ELR were all higher in children with allergic asthma than in children with non-allergic asthma(P<0.05),and platelet/lymphocyte ratio(PLR)was lower than that in children with non-allergic asthma(P<0.05).Peripheral blood LYMPH,PLT,EOS and ELR of children with allergic asthma differed between four seasons,which were higher than those of non-allergic asthma in each season in EOS and ELR,LYMPH was significantly higher than that of children with non-allergic asthma in autumn,and PLT was significantly lower than that of children with non-allergic asthma in spring(P<0.05).EOS predicted AUC of spring,summer,autumn and winter were 0.79,0.77,0.71 and 0.64 in children with allergic asthma,and ELR predicted AUC were 0.72,0.48,0.73 and 0.68 in children with allergic asthma.Conclusion:Allergic asthma in children is seasonally variable and peaks in autumn.EOS and ELR in peripheral blood cells in children with allergic asthma are higher than in children with non-allergic asthma in each season of year,LYMPH is significantly higher than children with non-allergic asthma in the fall,and PLT is lower than in children with non-allergic asthma in spring,suggesting that allergic asthma type Ⅱinflammation persists,and EOS and ELR have predictive value for children's allergic asthma.

Abstract: It is well-known that crystal form of a drug is a key factor impacting the physicochemical properties of the drug, which in turn affects its in vivo efficacy, safety and stability. The study on crystal forms of solid-state drugs is crucial for drug quality control, selection of production process and evaluation of clinical efficacy. The combination of chemometric and analytical techniques exhibited its great ability to analyze a large amount of multidimensional data, providing the possibility for quantification of trace amount of crystals (< 1%). Meanwhile, using the process analytical technology (PAT) to monitor the crystal content real-time during prescription preparation process can further realize the control on formulation quality and serve as a core technology to support the patent protection of crystalline forms. In this review, the combined application of crystal analytical techniques and chemometric methods for the quantitative analysis of trace crystals were summarized, aiming to provide guidance for the manufacturing of pharmaceutical preparations and their quality control.
