Objective To examine the possible factors affecting the attainment of target serum trough concentration of vancomycin in premature newborns for optimization of clinical dosing regimens.Methods The vancomycin trough concentration data were collected retrospectively from preterm newborns who received intravenous infusion of vancomycin from December 2016 to March 2021.According to the Evidence-based Guideline for Therapeutic Drug Monitoring of Vancomycin:2020 Update by the Division of Therapeutic Drug Monitoring,Chinese Pharmacological Society,the patients were assigned to failure(＜5 mg/L)or success(5-15 mg/L)in target attainment,or beyond target group(＞15 mg/L)base on vancomycin trough concentration.Statistical software SPSS was used to analyze differences in clinical characteristics between different groups,and profile various factors that may affect attainment of target serum trough concentration of vancomycin.Results The median(interquartile range)trough concentration of vancomycin was 12.50(7.95-18.05)mg/L in 82 preterm newborns.The target trough concentration of vancomycin was attained in 47 preterm newborns(57.32％),and the corresponding trough concentration of vancomycin was 10.90(7.80-13.30)mg/L.The trough concentration of vancomycin was beyond target in 27 preterm newborns(32.93％).The corresponding median trough concentration of vancomycin was 21.80(18.00-23.80)mg/L.Serum trough concentration of vancomycin failed to achieve the target in only 8 preterm newborns(9.75％).The corresponding median trough concentration was 4.10(2.48-4.60)mg/L.Univariate analysis showed that there were statistically significant differences(P＜0.05)in postmenstrual age and current weight between the patients succeeded in attaining target trough concentration and those who failed to attain the target.Baseline serum creatinine and dosing interval showed statistically significant differences(P＜0.01)between the newborns who attained the target concentration and those with higher trough concentration beyond the target.Multivariate regression analysis showed that baseline serum creatinine(OR=1.063,95％CI 1.024-1.102,P=0.001,cutoff:62 pmol/L)and dosing interval(OR=6.693,95％CI 1.604-27.920,P=0.009)were independent risk factors for excessively high vancomycin trough concentrations.Conclusions The dosing regimens as recommended in the current package insert only enable the attainment of target serum trough concentration of vancomycin in half of the premature newborns.The dosing regimen of vancomycin should be optimized by taking postmenstrual age,current weight,baseline serum creatinine and dosing interval into account.Therapeutic drug monitoring is necessary to ensure safety and effectiveness.

Objective:To explore the relationship among depression, social belonging and fertility quality of life of infertile women, and to provide a theoretical basis for the development of effective measures to improve the quality of life of infertile women.Methods:From July 2022 to October 2022, a random sample of 400 patients treated for infertility in the Reproductive Assisting Centre of the First Hospital of Anhui Medical University were selected using a general basic questionnaire, the Depression Screening Self-Rating Scale (PHQ-9), the Social Attribution Measurement Questionnaire and the Fertility Quality of Life Scale quality of life questionnaire (FertiQoL) were administered. Spearman correlation was used to analyze the association between the variables, and mediating effects were examined by Bootstrap procedure and PROCESS software.Results:The 400 infertile women had a median depression score of 5, reaching a subclinical mild level of depression, a median score of 12 on the social belonging measure, and a median score of 62.87 on the FertiQoL. Social belonging was negatively correlated with depression ( r=-0.206, P<0.001); social belonging was positively correlated with FertiQoL ( r=0.267, P<0.001); and depression was negatively correlated with FertiQoL ( r=-0.428, P<0.001). Mediation analysis showed that after controlling for relevant variables, the indirect effect of depression on FertiQoL in infertile women was -0.069 0 (95% CI: -0.173 3--0.008 3), and the direct effect was -1.019 1 (95% CI: -1.436 3- -0.601 8), the mediating effect of FertiQoL through social belonging on depression in infertile women accounted for 6.34% of the total effect. Conclusion:Social belonging plays a partial mediating role in depression and FertiQoL among infertile women. Infertile women should be given timely attention to their psychological situation and given more social recognition and support to improve their FertiQoL.

OBJECTIVE: To detect variants of the MMACHC gene among 110 ethnic Han Chinese pedigrees affected with metabolic deficiency methylmalonic acidemia (MMA) of cobalamin C (cblC). METHODS: Peripheral blood samples were collected from the probands and their parents. Following DNA extraction, the coding regions of the MMACHC gene were subjected to PCR amplification, Sanger sequencing and quantitative PCR assaying. For 48 pedigrees, chorionic villus samples were taken for prenatal genetic diagnosis. RESULTS: Thirty five types of variants were detected among the 110 pedigrees, which included missense, nonsense, frameshifting, splicing variants and exonic deletions. Most variants have occurred in exons 4 (73.18%). The detection rate for c.609G>A (p.Trp203Ter) variant was the highest (33.64%), followed by c.658_660delAAG (12.27%), c.567dupT (9.09%) and c.80A>G (6.82%). Two variants, namely c.57_58insT (p.Gly20Trpfs*14) and c.505_506delAT (p.Ile169Argfs*12), were unreported previously and both were of frameshifting types. For the 48 pedigrees undergoing prenatal diagnosis, 14 fetuses were found to be normal, 24 have carried heterozygous variants, the remaining 10 have carried compound heterozygous or homozygous variants. CONCLUSION The discovery of the two novel variants has expanded the spectrum of the MMACHC gene variants among ethnic Han population. Above finding has provide a basis for the prenatal diagnosis and genetic counseling for the affected pedigrees.

Objective:To analyze the clinical characteristics of patients with acute glyphosate herbicide poisoning and the differences in the severity of poisoning.Methods:A retrospective analysis was performed on patients with acute glyphosate herbicide poisoning admitted to the First Affiliated Hospital of Zhengzhou University from January 2014 to December 2020. The general information, exposure time, poisoning dose, poisoning cause, poisoning route, clinical manifestations, laboratory examination results during hospitalization, treatment measures, hospital stays and prognosis of the patients were collected. The patients were graded according to the poisoning severity scoring standard of Chinese Expert Consensus on Diagnosis and Treatment of Acute Poisoning in 2016. The highest severity score during hospitalization was used as the final grade. According to the final grade, asymptomatic and mild patients were included in the mild group, and moderate, severe and death patients were included in the severe group. The independent sample T test or Mann-Whitney U test was used for measurement data, and χ2 test or Fisher's exact test was used for counting data. The differences of general data and clinical data between the two groups were compared. Results:According to the inclusion and exclusion criteria, 83 patients with acute glyphosate herbicide poisoning were selected as the study subjects. All patients survived, mainly mild poisoning (56.6%), with a male to female ratio of 33∶50, and an average age of 39 years. The number of poisoning cases increased yearly (the highest in 2019), and most cases occurred in spring and summer. The main cause of poisoning was suicide (71.1%), direct oral administration (83.1%) was the primary route of poisoning, and the dominating clinical manifestations were digestive symptoms (71.1%). Laboratory tests showed increased white blood cell count (WBC), neutrophil percentage (NEUT %) and D-dimer, and decreased hemoglobin and potassium. Compared with the mild group, patients in the severe group were older [(51±17) years vs. (35±19) years], had a higher proportion of suicide and direct oral administration, a longer hospital stay [8.0 (4.8, 12.0) d vs. 3.0 (2.0, 5.5) d], a higher dose of poisoning [200.0 (50.0, 200.0) mL vs. 30.0 (11.3, 57.5) mL], and higher NEUT % within 24 h of admission [(83.4±10.4) vs. (73.2±12.8)]. The increase of WBC, NEUT %, aspartate aminotransferase, prothrombin time, D-dimer and the decrease of serum potassium were more common in the severe group than the mild group, with statistical significance (all P<0.05). Conclusions:The number of patients with acute glyphosate herbicide poisoning is increasing yearly. Generally, the condition is mild and the prognosis is satisfying. The severity is more serious in the middle-aged and elderly patients andthose with direct oral administration, high toxic dose, and high NEUT % within 24 h of admission. Severe poisoning is more likely to cause changes in laboratory indicators.
