OBJECTIVE To investigate the current status of quality management of cold chain medicines in direct-to-patient （DTP） pharmacies and propose measures for pre-emptive risk management， providing references for the quality risk management of cold chain medicines. METHODS Based on the requirements of national regulations， a survey was conducted on the quality management of cold chain medicines in DTP pharmacies of J Province from November 2023 to February 2024， focusing on the receipt， storage， distribution， and delivery processes， using questionnaires， telephone interviews， and on-site visits. Common quality management issues in the operation of cold chain medicines were identified， and the causes of these issues were analyzed to propose feasible pre-emptive risk management measures. RESULTS & CONCLUSIONS A total of 122 DTP pharmacies participated in the questionnaire survey， and personnel from 30 DTP pharmacies participated in on-site and telephone interviews. Typical problems were identified in some DTP pharmacies， including insufficient personnel allocation or training， incomplete or inadequate implementation of quality system documentation， inadequate provision or management of cold chain facilities and equipment， and non-compliant storage and distribution of cold chain medicines. These issues posed certain risks to the quality management of cold chain medicines. It is recommended that DTP pharmacies strengthen personnel allocation and training， improve quality system documentation， enhance the provision and management of facilities and equipment， standardize storage and transportation operations， and strengthen supervision and assessment as pre-emptive measures. In addition， all sectors of society should also collaborate in governance from the perspective of ensuring the safety of cold chain drug storage and transportation， in order to mitigate the risk of quality and safety issues during the distribution of cold chain drugs and guarantee the safe and effective use of medications for patients.

BACKGROUND: The effect of the interval between previous Helicobacter pylori (H. pylori) eradication and rescue treatment on therapeutic outcomes remains unknown. The aim of this study was to investigate the association between eradication rates and treatment interval durations in H. pylori infections. METHODS: This prospective observational study was conducted from December 2021 to February 2023 at six tertiary hospitals in Shandong, China. We recruited patients who were positive for H. pylori infection and required rescue treatment. Demographic information, previous times of eradication therapy, last eradication therapy date, and history of antibiotic use data were collected. The patients were divided into four groups based on the rescue treatment interval length: Group A, ≥4 weeks and ≤3 months; Group B, >3 and ≤6 months; Group C, >6 and ≤12 months; and Group D, >12 months. The primary outcome was the eradication rate of H. pylori . Drug compliance and adverse events (AEs) were also assessed. Pearson's χ2 test or Fisher's exact test was used to compare eradication rates between groups. RESULTS: A total of 670 patients were enrolled in this study. The intention-to-treat (ITT) eradication rates were 88.3% (158/179) in Group A, 89.6% (120/134) in Group B, 89.1% (123/138) in Group C, and 87.7% (192/219) in Group D. The per-protocol (PP) eradication rates were 92.9% (156/168) in Group A, 94.5% (120/127) in Group B, 94.5% (121/128) in Group C, and 93.6% (190/203) in Group D. There was no statistically significant difference in the eradication rates between groups in either the ITT ( P = 0.949) or PP analysis ( P = 0.921). No significant differences were observed in the incidence of AEs ( P = 0.934) or drug compliance ( P = 0.849) between groups. CONCLUSION: The interval duration of rescue treatment had no significant effect on H. pylori eradication rates or the incidence of AEs. REGISTRATION ClinicalTrials.gov , NCT05173493.

Objective To explore the impact of SARS-CoV-2-positive donors on the prognosis of heart transplant recipients. Methods The Medline, EMbase, CENTRAL, CNKI, Wanfang Data, VIP and China Biology Medicine from inception to May 2023 were searched by computer for studies about impact of SARS-CoV-2-positive donors on the prognosis of heart transplant recipients. The data were extracted from all the relevant literatures, and the quality of the data was assessed using the Newcastle-Ottawa Scale (NOS). All statistical analyses were conducted by the Stata 11.0 software. Results A total of 10 studies (NOS score ranging from 5 to 9 points) involving 643 patients were enrolled. The pooled results demonstrated that the pooled mortality of heart transplant recipients from SARS-CoV-2-positive donors was 4% (95%CI 2% to 5%). And the incidence of composite outcome, regarding graft failure, rejection and death as poor prognosis, was 7% (95%CI 5% to 9%). Besides, compared with recipients from SARS-CoV-2-negative donors, the pooled odds ratio (OR) value of death of SARS-CoV-2-positive donors was 0.68 (95%CI 0.38 to 1.22, Z=1.28, P=0.200). The pooled OR value of rejection rate was 0.41 (95%CI 0.27 to 0.64, Z=3.97, P<0.005). For the composite outcome, the pooled OR value was 0.50 (95%CI 0.37 to 0.69, Z=4.30, P<0.005). In addition, there was no statistical difference in the length of hospital stay between heart transplant recipients from SARS-CoV-2-positive donors and negative donors (SMD=–0.03, 95%CI –0.22 to 0.15, Z=0.36, P=0.720). Conclusion The application of heart from SARS-CoV-2-positive donor for transplantation is safe and feasible. However, further prospective studies with longer follow-up are still needed to verify its impact on long-term outcomes.

ObjectiveTo investigate the association of the polymorphisms of the acetyl-CoA acetyltransferase 1 （ACAT1） gene and the melatonin receptor 1B （MTNR1B） gene with the susceptibility to nonalcoholic fatty liver disease （NAFLD）. MethodsA total of 164 healthy controls and 228 NAFLD patients were enrolled in this study. PCR and sequencing methods were used to determine the genotypes of the polymorphisms of the ACAT1 gene at the rs1044925 and rs1157651 loci and the MTNR1B gene at the rs10830963 locus， and fasting venous blood samples were collected for biochemical analysis. The t-test was used for comparison of normally distributed continuous data between groups， and the non-parametric Mann-Whitney U test was used for comparison of non-normally distributed continuous data between groups； the chi-square test was used for comparison of categorical data between groups. ResultsThere were no significant differences between the NAFLD group and the healthy control group in the genotype distribution of the ACAT1 gene at the rs1044925 and rs1157651 loci and the MTNR1B gene at the rs10830963 locus （all P>0.05）. The carriers of AA genotype at the rs1044925 locus of the ACAT1 gene had a significantly higher level of low-density lipoprotein than the carriers of C allele （Z=-2.08， P=0.04）， and the carriers of G allele at the rs10830963 locus of the MTNR1B gene had a significantly higher level of fasting blood glucose than the carriers of CC genotype （Z=-3.01， P<0.01）. ConclusionThe polymorphisms of the ACAT1 gene at the rs1044925 and rs1157651 loci and the MTNR1B gene at the rs10830963 locus were not associated with the susceptibility to NAFLD. The rs1044925 locus of the ACAT1 gene and the rs10830963 locus of the MTNR1B gene are associated with the levels of low-density lipoprotein and fasting blood glucose， respectively.

Objective:To explore the genetic basis for a patient with Disorders of sex development (DSD).Methods:A female patient who had presented at the Linyi People′s Hospital due to primary amenorrhea on April 6, 2022 was selected as the study subject. Conventional chromosomal karyotyping, fluorescence in situ hybridization (FISH), chromosomal microarray analysis (CMA), fluorescence quantitative PCR and Sanger sequencing were carried out for the patient. Results:The patient, a 14-year-old female, had featured short statue, multiple nevi, and primary amenorrhea. She was found to have a karyotype of 46, X, idic(Y)(p11.3)[59]/45, X[39]/47, X, idic(Y)(p11.3)×2[2]. The result of FISH assay was 46, X, der(Y).ish idic(Y)(p11.3)( SRY+ )[59]/45, X[39]/47, X, der(Y)×2.ish idic(Y)(p11.3)( SRY+ )[2]. That of CMA was arr[GRCh37](X)×1, (Y)×0-1, arr[GRCh37]Yp11.32(118552_472090)×1. The patient had no deletion in the AZF region of Y chromosome, and was negative for variant of SRY gene. Combining the above results, her molecular karyotype was determined as mos 46, X, idic(Y)(p11.32)[59]/45, X[39]/47, X, idic(Y)(p11.32)×2[2].ish 46, X, idic(Y)(p11.32)( DXZ1+, DYZ1+ +, DYZ3+ +, SRY+ )[59]/45, X( DXZ1+, DYZ1-, DYZ3-, SRY-)[39]/47, X, der(Y)×2.ish idic(Y)(p11.32)( DXZ1+, DYZ1+ +, DYZ3+ +, SRY+ )[2].arr[GRCh37](X)×1, (Y)×0-1, arr[GRCh37]Yp11.32(118552_472090)×1. The patient was diagnosed with mosaicism DSD with idic(Y)(p11.32). Conclusion:The abnormal mosaicism karyotype probably underlay the DSD in this patient.

Objective:To investigate the clinical and genetic characteristics of a child with microcephaly-capillary malformation syndrome due to a STAMBP mutation. Methods:The clinical data of a case of microcephaly-capillary malformation syndrome caused by STAMBP gene mutation admitted to Anhui Children′s Hospital in August 2023 were collected. The genes of the child and his parents were detected by whole exome sequencing, and the risk was predicted by biological software. At the same time, the clinical characteristics of the child were analyzed and the literature was reviewed. Results:The patient is a male child aged 2 years and 7 months. The patient had special features, microcephaly, refractory epilepsy, severe comprehensive developmental delay, and capillary malformations. The results of genetic testing showed that the STAMBP gene in the child had complex heterozygous mutations NM_001353967: c.367delG[p.E123fs *27(p.Glu123fsTer27) and c.159A>C(p.Glu53Asp)], inherited from his mother and father respectively. The mutations have not been recorded in the HGMD, dbSNP and gnomAD databases,etc. The protein structure of the STAMBP gene was modeled that predicted c.367del(p.Glu123Lysfs *27) and c.159A>C (p.Glu53Asp) had a negative effect on the function of STAMBP protein. Conclusion:The STAMBP gene complex heterozygous mutations c.367delG(p.Glu123fsTer27) and c.159A>C(p.Glu53Asp) may be the pathogenic factor of this child, which further expands the variation spectrum of the STAMBP gene and the genotype of microcephaly-capillary malformation syndrome, and provides guidance for family genetic counseling.
