bstract: Objective To elucidate the distribution characteristics of mosquito species and the population genetic diversity of important mosquito species in the Wuyi Mountain Nature Reserve, with the aim of providing a scientific basis for the prevention and control of mosquito-borne diseases in the region. Methods Within Wuyi Mountain Nature Reserve 2022- 2023, 16 sampling sites were selected, where larvae were collected using the pipette method and adult mosquitoes were collected using the mosquito trap lamp method. Mosquito species identification was accomplished by integrating morphological characteristics and molecular identification techniques based on CO Ⅰ and CO Ⅱ gene sequences. Software tools such as ClustalX, DnaSP v5.0, and Network v4.6.1.0 were utilized to analyze the genetic differentiation (Fst), gene flow (Nm) among populations of Aedes japonicus, Aedes albopictus and Armigeres subalbatus. Results The mosquito specimens collected from the Wuyi Mountain Nature Reserve were identified as 30 species belonging to 8 genera within the Culicidae family. Among them, there were 10 species of Aedes, 13 species of Culex, 1 species each of Armigeres, Orthopodomyia, Uranotaenia, Tripyeroides, and Anopheles, and 2 species of Toxorhynchites. Analysis of the genetic structure of important mosquito populations showed that the haplotype diversity index (Hd) of Ae. japonicus was 0.994 7, with a generally moderate degree of differentiation between populations and a higher degree of genetic differentiation between populations 6 and 12; Aedeslbopictus had a haplotype diversity index of 0.634 0, with significant genetic differentiation between populations 1 and 2 compared to other groups; Armigeres subalbatus had a haplotype diversity index of 0.703 3, with substantial genetic differentiation and limited gene flow between population 2 and populations 3, 4, 6, and 7. Conclusions The mosquito species are rich in Wuyi Mountain Nature Reserve. A comprehensive survey of the composition and distribution of mosquito populations was carried out, and the characteristics of the population genetic structure of the important species of Ae. japonicus, Ae. Albopictus, and Ar. subalbatus populations were analyzed, providing valuable scientific data reference for local mosquito-borne ecological research and disease prevention and control.

Objective:To explore and establish a standardized clinical thinking mode and decision-making pathway for lactation medication consultation services and ensure the harmonization and safety of medication for lactating women.Methods:Lactation medication consultation services for medical staffs conducted by pharmacists from June 2020 to August 2022 in Peking University Third Hospital were analyzed using methods of retrospective statistical analysis and root cause analysis. Application of mixed methods were used to establish a clinical thinking model for medication use during lactation and a clinical pathway for safe medication use during lactation. Lactation medication consultation service training for pharmacists was provided, questionnaire surveys before and after the training were conducted, and the effectiveness of improvement was evaluated.Results:A total of 1 218 medication consultation services provided by clinical pharmacists to medical staffs were collected in the hospital, including 44 cases (3.61%) related to lactation medication. Retrospective analysis showed that clinical pharmacists did not have a clear understanding of patients′ needs, incomplete consideration of drug-maternal-infant factors, and a limited way to retrieve information in the lactation medication consultation service. Based on the root cause analysis of the problems, a clinical thinking mode of "Questions (Q), Assessment (A), Search (S), and Plan (P)" (QASP) were established. Additionally, a clinical pathway for safe medication decision-making analysis and a standard medication consultation record template was developed. Compared with before training, clinical pharmacists made significant progress in clarifying factors related to lactation medication, evidence-based procedure, standardized documentation, and confidence in providing medication consulations (all P<0.001). Conclusion:The establishment of the QASP clinical thinking model and decision analysis model, based on the 3 factors of medication, mother, and baby for the consultation service of safe medication during lactation, can help clinical pharmacists carry out standardized medication consultation services for breast-feeding populations during lactation, and improve the quality of homogeneous pharmaceutical services.

Objective:To analyze the factors influencing pH value in umbilical arterial blood gas (UABG) analysis in preterm infants.Methods:A retrospective study was conducted on live singleton preterm infants ( n=573) who received UABG analysis in Peking University Third Hospital from January 2017 to February 2019. Analysis of variance, independent sample t-test, Spearman's or Pearson's correlation analysis, or linear regression analysis was used to analyze the influencing factors. Results:There was no significant difference in UABG pH value between preterm infants of different gestational ages (F=1.74, P=0.077). Spearman's correlation analysis found no correlation between gestational age and UABG pH value in premature infants ( r=0.003, P=0.940), and neither did Pearson's correlation between birth weight and pH value ( r=0.025, P=0.548). UABG pH value in preterm infants was linearly correlated with vaginal delivery ( t=－5.72, P<0.001), gestational hypertension ( t=－3.99, P<0.001) and placental abruption ( t=－4.52, P<0.001). Conclusions:Preterm infants at different gestational ages show a similar pH value in UABG. For those born to mothers with gestational hypertension or placental abruption, when vaginal delivery is pending, close monitoring and full preparation for resuscitation are necessary.

Objective:To investigate the relationship of umbilical arterial blood pH with Apgar score and its perinatal influencing factors as well as effects on short-term neonatal outcomes.Methods:This study retrospectively collected the clinical data of 7 183 singleton newborns who were born at ≥35 gestational weeks with umbilical artery blood gas analysis in Peking University Third Hospital from January 2017 to February 2019. All cases were divided into two groups according to their Apgar scores at 1 min: low Apgar group (≤7 scores, n=42) and normal Apgar group (>7 scores, n=7 141). Moreover, according to the pH value of umbilical artery blood they were also allocated into acidosis group (pH<7.2, n=379 ) and normal pH group (pH≥7.2, n=6 804). Independent sample t test, Chi-square test, Fisher's exact test, Pearson's correlation analysis and multivariate logistic regression analysis were used to analyze the correlation between umbilical arterial blood pH and Apgar score, effects of perinatal complications on umbilical arterial blood pH, and influences of acidosis on early neonatal outcomes. Results:The umbilical arterial blood pH in the low Apgar group was significantly lower than that in the normal Apgar group (7.19±0.13 vs 7.32±0.07, t=-6.011, P<0.001). There was a positive correlation between the umbilical arterial blood pH and Apgar score at 1 min ( r=0.217, P<0.001). Fetal distress was an independent risk factor for low Apgar score ( OR=20.553, 95% CI: 4.380-96.443, P<0.001). Premature rupture of membranes was an independent risk factor for acidosis ( OR=1.316, 95% CI: 1.035-1.673, P=0.025). The incidence of low Apgar score [6.33% (24/379) vs 0.26% (18/6 804), χ2=217.075], respiratory distress [6.60% (25/379) vs 2.62% (178/6 804), χ2=21.205] and intracranial hemorrhage [1.06% (4/379) vs 0.04% (3/6 804), Fisher's exact test] was significantly higher in the acidosis group than in the normal pH group (all P<0.001). Conclusions:Neonates with lower umbilical arterial blood pH value should be closely monitored after birth as they are more likely to have respiratory distress and intracranial hemorrhage. Umbilical arterial blood pH value may be effective and is recommended in predicting neonatal early outcome.

BACKGROUND: Chronic kidney disease is a severe threat to human health with no ideal treatment strategy. Mature mammalian kidneys have a fixed number of nephrons, and regeneration is difficult once they are damaged. For this reason, developing an efficient approach to achieve kidney regeneration is necessary. The technology of the combination of decellularized kidney scaffolds with stem cells has emerged as a new strategy; however, in previous studies, the differentiation of stem cells in decellularized scaffolds was insufficient for functional kidney regeneration, and many problems remain. METHODS: We used 0.5% sodium dodecyl sulfate (SDS) to produce rat kidney decellularized scaffolds, and induce adipose-derived stem cells (ADSCs) into intermediate mesoderm by adding Wnt agonist CHIR99021 and FGF9 in vitro. The characteristics of decellularized scaffolds and intermediate mesoderm induced from adipose–derived stem cells were identified. The scaffolds were recellularized with ADSCs and intermediate mesoderm cells through the renal artery and ureter. After cocultured for 10 days, cells adhesion and differentiation was evaluated. RESULTS: Intermediate mesoderm cells were successfully induced from ADSCs and identified by immunofluorescence and Western blotting assays (OSR1 + , PAX2 +). Immunofluorescence showed that intermediate mesoderm cells differentiated into tubular-like (E-CAD + , GATA3 +) and podocyte-like (WT1 +) cells with higher differentiation efficiency than ADSCs in the decellularized scaffolds. Comparatively, this phenomenon was not observed in induced intermediate mesoderm cells cultured in vitro. CONCLUSION: In this study, we demonstrated that intermediate mesoderm cells could be induced from ADSCs and that they could differentiate well after cocultured with decellularized scaffolds.
