The detection rate of prenatal depression in Chinese women: a meta-analysis / 预防医学

Objective@#To systematically evaluate the detection rate of prenatal depression in Chinese women, so as to provide the reference for mental health care during pregnancy among women.@*Methods@#Publications pertaining to the detection rate of prenatal depression in Chinese women were retrieved from international and national databases from inception to July 30, 2023, including CNKI, Wanfang Data, VIP, PubMed and other databases. The Stata 17.0 software was used for meta analysis, sensitivity analysis was performed using the leave-one-out method, and the publication bias was evaluated using funnel plot and Egger's test.@*Results@#A total of 5 687 publications were retrieved, and 60 studies were finally included, with 58 in Chinese and 2 in English, 51 of medium quality and 9 of high quality, and 114 168 participants. The results of meta-analysis showed that the overall detection rate of prenatal depression in Chinese women was 23.7% (95%CI: 20.0%-27.5%). The detection rates of prenatal depression in the first, second and third trimesters were 22.1% (95%CI: 15.5%-28.6%), 16.3% (95%CI: 12.0%-20.6%) and 19.9% (95%CI: 16.0%-23.7%), in Eastern and Midwestern China were 19.7% and 27.5%, and in women with an education level of junior high school or below and high school or above were 27.2% and 17.9%, respectively, with statistically significant differences (all P<0.05). Sensitivity analysis showed that the study results were stable. There were publication bias in the results of overall detection rate of prenatal depression, and detection rates in the second and third trimester.@*Conclusions@#The overall detection rate of prenatal depression in Chinese women ranges from 20.0% to 27.5%. There are differences in the detection rate of prenatal depression in different pregnancies, with the highest detection rate in the first trimester.

Effects of broken window effect and narrative nursing intervention on adolescent non-suicidal self-injury / 预防医学

Objective@# To evaluate the intervention effectiveness of broken window effect combined with narrative nursing on non-suicidal self-injury (NSSI) in adolescents, so as to provide the basis for NSSI prevention in adolescents.@*Methods@#Totally 134 adolescents with NSSI admitted to Mental Health Center of the Affiliated Hospital of Anhui West Health Vocational College from January 2022 to December 2023 were enrolled and randomly assigned into the control and treatment group. All were given narrative nursing and routine care, and the adolescents in the treatment group were given additional intervention based on broken window effect. The effects were evaluated using Self-Rating Depression Scale (SDS), Hamilton Depression Scale (HAMD), Self-Rating Idea of Suicide Scale (SIOSS), Ottawa Self-injury Inventory-Functions (OSI-F) and Nursing Satisfaction Scale, and the two groups were compared before and after intervention.@*Results@#The treatment and control groups comprised 67 cases each, had a median age of 14.12 (interquartile range, 2.01) years and 14.10 (interquartile range, 1.52) years, included 71.64% and 68.66% girls, and 79.10% and 74.63% junior high school students, respectively. There were no statistically significant differences between the treatment and control groups in terms of gender, age or educational level (all P>0.05). The results of analysis of variance for repeated measures showed that there were interactions between time and group for SDS, HAMD and SIOSS scores (all P<0.05), and the decrease in scores before and after intervention was greater in the treatment group than in the control group. After intervention, the SDS, HAMD, SIOSS score and incidence of suicidal behaviors in the treatment group were all lower than the control group [SDS: (32.54±1.27) vs. (44.25±2.23); HAMD: (10.54±1.83) vs. (18.73±1.89); SIOSS: (10.37±2.20) vs. (15.76±1.62); incidence of suicidal behavior: 14.93% vs. 32.84%; all P<0.05]. The nursing satisfaction rate was significantly higher in the treatment group than in the control group (98.51% vs. 88.06%, P<0.05).@*Conclusion@#The broken window effect combined with narrative nursing would improve the depressive symptoms in adolescents with NSSI, and reduce the suicidal ideation and self injury.

Repair of large traumatic tympanic membrane perforation using ofloxacin otic solution and gelatin sponge / Reparo de grande perfuração da membrana timpânica traumática utilizando solução otológica de ofloxacina e curativo de Gelfoam®

Abstract Introduction Traumatic large tympanic membrane perforations usually fail to heal and require longer healing times. Few studies have compared the healing and hearing outcomes between gelatin sponge patching and ofloxacin otic solution. Objectives To compare the healing outcomes of large traumatic tympanic membrane perforations treated with gelatin sponge, ofloxacin otic solution, and spontaneous healing. Methods Traumatic tympanic membrane perforations >50% of the entire eardrum were randomly divided into three groups: ofloxacin otic solution, gelatin sponge patch and spontaneous healing groups. The healing outcome and hearing gain were compared between the three groups at 6 months. Results A total of 136 patients with large traumatic tympanic membrane perforations were included in analyses. The closure rates were 97.6% (40/41), 87.2% (41/47), and 79.2% (38/48) in the ofloxacin otic solution, gelatin sponge patch, and spontaneous healing groups, respectively (p = 0.041). The mean times to closure were 13.12 ± 4.61, 16.47 ± 6.24, and 49.51 ± 18.22 days in these groups, respectively (p < 0.001). Conclusions Gelatin sponge patch and ofloxacin otic solution may serve as effective and inexpensive treatment strategies for traumatic large tympanic membrane perforations. However, ofloxacin otic solution must be self-applied daily to keep the perforation edge moist, while gelatin sponge patching requires periodic removal and re-patching.

Resumo Introdução As grandes perfurações traumáticas da membrana timpânica geralmente apresentam falha de cicatrização e requerem tempos de cicatrização mais longos; poucos estudos compararam os resultados de cicatrização e a audição dessas perfurações obtidos com curativo de Gelfoam® e solução otológica de ofloxacina. Objetivo Comparar os resultados de cicatrização de grandes perfurações traumáticas da membrana timpânica tratadas com Gelfoam®, solução otológica de ofloxacina e cicatrização espontânea. Método Perfurações traumáticas de > 50% de todo o tímpano foram divididas aleatoriamente em três grupos: tratamento com solução otológica de ofloxacina, com curativo de Gelfoam® e grupo de cicatrização espontânea. O resultado da cicatrização e o ganho auditivo foram comparados entre os três grupos após 6 meses. Resultados Foram incluídos nas análises 136 pacientes com grandes perfurações traumáticas de membrana timpânica. As taxas de cicatrização foram de 97,6% (40/41), 87,2% (41/47) e 79,2% (38/48) com a solução otológica de ofloxacina, curativo de Gelfoam® e grupos de cicatrização espontânea, respectivamente (p = 0,041). O tempo médio de cicatrização foi de 13,12 ± 4,61, 16,47 ± 6,24 e 49,51 ± 18,22 dias nesses grupos, respectivamente (p < 0,001). Conclusões O curativo de Gelfoam® e a solução otológica de ofloxacina podem servir como estratégias de tratamento eficazes e de baixo custo para grandes perfurações traumáticas de membrana timpânica. Entretanto, a solução otológica de ofloxacina deve ser autoaplicada diariamente para manter a borda da perfuração úmida, enquanto o curativo de Gelfoam® requer sua remoção e reaplicação periódicas.

Research progress on the correlation between herpangina and hand⁃foot⁃mouth disease / 口腔疾病防治

@# As acute enterovirus⁃induced infections, herpangina(HA) and hand⁃foot⁃mouth disease(HFMD) are simi⁃lar in many aspects. Although these diseases vary with time and region, many studies have shown that the viruses caus⁃ing HA and HFMD are consistent, and there is no notable difference in partial VP1 gene sequences between different vi⁃ruses. HA and HFMD also resemble each other in epidemiological features. Both infections show significant summer⁃time seasonality, have a strong connection with certain environmental conditions and are most prevalent in young chil⁃dren and infants. Herpangina is thought to be a mild disease, defined as vesicular enanthem and then ulcers of the fau⁃ces and soft palate with presentation of feve r, sore throat, and decreased appetite. HFMD, which could lead to severe symptoms, is also characterized by oral ulcers, although they are chiefly on the buccal mucosa and tongue, and typical vesicular rashes, which are most commonly found on the hands, feet, knees and buttocks. While HA is generally be⁃ lieved to be self⁃limited and has a favorable prognosis, HA with certain clinical characteristics, such as diarrhea, vomit⁃ing, limb jitter and sleepiness, can evolve into HFMD, according to some literature in recent years. However, HA is an independent risk factor for HFMD, and severe cases only present with herpes appearing at the isthmus of the fauces at an early stage, which indicates a strong correlation between them. Clinical manifestations of HA should be considered by medical staff to identify potential children with HFMD as early as possible to prevent its further development or transformation.

Impact of chrysosplenetin, per se or in combination with artemisinin, on breast cancer resistance protein (Bcrp)/ABCG2 mRNA expression levels in mice small intestine

ABSTRACT Our previous work revealed that chrysosplenetin in combination with artemisinin inhibited in vivo P-glycoprotein (P-gp, one of classic multi-drug resistance proteins) mediated digoxin transportation activity by reversing the upregulated P-gp/Mdr1 mRNA expression levels by artemisinin. Therefore, chrysosplenetin might be a potential artemisinin-resistance reversal agent as a P-gp inhibitor. But it still remains unknown if chrysosplenetin has an impact on another pivotal multi-drug resistance protein, breast cancer resistance protein (Bcrp), which is co-expressed with P-gp in apical membrane of intestinal epithelial cell and overlaps some of the substrates and inhibitors. This study, therefore, further addressed the impact of chrysosplenetin, per se or in combination with artemisin, on Bcrp/ABCG2 mRNA expression levels in mice small intestine determined by western blot and real time-quantitative polymerase chain reaction (RT-qPCR) assay. The drugs were intragastrically administrated once per day for 7 days. Novobiocin, a known Bcrp inhibitor, was observed to have no impact on Bcrp/ABCG2 levels with or without artemisinin versus vehicle. Interestingly, artemisinin alone attenuated Bcrp level while chrysosplenetin alone increased it (p < 0.05). Relative mRNA level was significantly decreased when co-used with artemisinin and chrysosplenetin in ratio of 1:2 (p < 0.05). The discrepant results for chrysosplenetin on Bcrp/ABCG2 mRNA expressions might be closely related to the transcriptional or posttranscriptional regulation.

Chrysosplenetin, in the absence and presence of artemsininin, alters breast cancer resistance protein-mediated transport activity in Caco-2 cell monolayers using aristolochic acid I as a specific probe substrate

ABSTRACT The present study describes the impact of chrysosplenetin, in the absence and presence of artemisinin, on in vitro breast cancer resistance protein-mediated transport activity in Caco-2 cell monolayers using aristolochic acid I as a specific probe substrate. We observed that novobiocin, a known breast cancer resistance protein active inhibitor, increased Papp (AP-BL) of aristolochic acid I 3.13 fold (p < 0.05) but had no effect on Papp (BL-AP). Efflux ratio (PBA/PAB) declined 4.44 fold (p < 0.05). Novobiocin, consequently, showed a direct facilitation on the uptake of AAI instead of its excretion. Oppositely, both artemisinin and chrysosplenetin alone at dose of 10 µM significantly decreased Papp (BL-AP) instead of Papp (AP-BL). Chrysosplenetin alone attenuated the efflux ratio, which was suggestive of being as a potential breast cancer resistance protein suppressant. Oddly, Papp (BL-AP) as well as efflux ratio were respectively enhanced 2.52 and 2.58 fold (p < 0.05), when co-used with artemisinin and chrysosplenetin in ratio of 1:2. The potential reason remains unclear; it might be relative to binding sites competition between artemisinin and chrysosplenetin or the homodimer/oligomer formation of breast cancer resistance protein bridged by disulfide bonds, leading to an altered in vitro breast cancer resistance protein-mediated efflux transport function.

Development of a UPLC–MS/MS method for determination of pimavanserin tartrate in rat plasma:Application to a pharmacokinetic study / 药物分析学报

A simple, rapid and sensitive method based on an ultra-performance liquid chromatography–tandem mass spectrometry(UPLC–MS/MS)has been developed and validated for the determination of pimavanserin in rat plasma.The analyte was extracted by protein precipitation with methanol and separated on an ACQUITY BEH C18column(100 mm×2.1 mm,1.7μm;Waters,USA),with an isocratic elution of acetonitrile-water containing 10 mM ammonium acetate (70:30, v/v), at a flow rate of 0.2 mL/min for 2.5 min. The analyte and clarithromycin (the internal standard) were detected and quantified in positive ion mode using multiple reaction monitoring transitions at m/z 428.2 → 223.0 for pimavanserin and m/z 748.5 → 589.5 for clarithromycin. Relative coefficient (r) for the calibration curve was more than 0.9980. The intra-day and inter-day precisions(relative standard deviation,RSD%)were less than 13.3% and 10.5%,respectively,and the accuracy(relative error,RE%)was within ± 11.5%.The analytical method was successfully applied to a routine pharmacokinetic study of pimavanserin in rats after oral administration at the dose of 10 mg/kg.
