With the intensification of population aging, type 2 diabetes has emerged as a significant global public health concern, particularly in developing countries.Epidemiological data indicate that the elderly population faces a higher risk of diabetes, accompanied by an increasing incidence rate.Due to the unique pathological characteristics and comorbid chronic diseases prevalent among elderly diabetes patients, polypharmacy is both common and often unavoidable.Inappropriate polypharmacy poses heightened health risks for patients and complicates clinical management, underscoring the urgent need to optimize intervention strategies.Effective approaches include regular medication reviews, adjustments to blood glucose control targets, and the development of personalized deprescribing plans informed by comprehensive geriatric assessments.While some interventions have demonstrated positive effects in reducing potentially inappropriate medications, addressing prescription omissions, and enhancing medication adherence, their capacity to yield significant clinical improvements requires further validation.Future research should prioritize the identification of the most effective interventions for high-risk populations.

The SEPN1 gene encodes selenoprotein N,and mutations in this gene can cause SEPN1-re-lated myopathy(SEPN1-RM).SEPN1-RM is an extremely rare and complex congenital myopathy with an in-sidious onset and slow progression,often leading to multi-system involvement.The main clinical manifestations include axial and proximal muscle weakness,early respiratory dysfunction,and spinal deformities.This article reports the diagnosis and treatment conditions for a pediatric patient carrying novel mutation in SEPN1 gene who underwent spinal orthopedic fusion surgery.After detailed multidisciplinary evaluation,adequate preoperative preparation,and meticulous perioperative management,the patient successfully underwent high-risk spinal or-thopedic surgery and recovered well.Based on the patient's diagnosis,perioperative management,and follow-up,combined with the latest domestic and international literature,this article systematically discusses the diag-nostic and therapeutic characteristics of this rare disease.The aim is to enhance clinicians'understanding of such diseases and to provide evidence-based support and reference for perioperative comprehensive management for such diseases.

Objective·To analyze the diversity and composition of the maternal gut microbiota and vaginal microbiota in late pregnancy,neonatal meconium microbiota and vernix caseosa microbiota,and analyze the similarities,differences and correlations.Methods·This is a prospective study.Maternal stool samples and vaginal swabs in late-pregnancy,and neonatal meconium samples were collected from 11 mother-infant pairs at Xinhua Hospital,Shanghai Jiao Tong University School of Medicine from August to November 2018;the vernix caseosa from three sites(forehead,axilla,and inguinal crease)and meconium samples were collected from 14 healthy newborns at International Peace Maternity and Child Health Hospital,Shanghai Jiao Tong University School of Medicine in December 2018.All births were vaginal deliveries.The 16S rRNA gene V3?V4 region sequencing was used.The diversity,composition and similarities/differences of the maternal gut microbiota,the vaginal microbiota,and the neonatal meconium microbiota from the 11 mother-infant pairs,as well as the neonatal vernix caseosa microbiota and the meconium microbiota from the 14 newborns were analyzed.Results·The number of operational taxonomic units(OTUs),ACE index,Chao1 index,and Shannon index of maternal gut microbiota were all higher than those of vaginal microbiota;the ACE indices and the Chao1 indices of the vernix caseosa microbiota at three sites were all higher than those of meconium microbiota(P<0.01).The β diversity varied among the maternal gut microbiota,vaginal microbiota,and neonatal meconium microbiota(P<0.01).The β diversity of neonatal vernix caseosa microbiota from three sites(forehead,axilla,and inguinal crease)was similar,but different from meconium microbiota(P<0.01).At the phylum level,the dominant bacteria were Firmicutes(52.76%)and Bacteroidetes(41.67%)in the maternal gut microbiota,Firmicutes(74.36%)and Actinobacteria(21.25%)in the maternal vaginal microbiota,and Firmicutes(84.22%)and Proteobacteria(8.80%)in the neonatal vernix caseosa microbiota.The dominant bacterium in the neonatal meconium was Proteobacteria in the two batches of samples(81.11%and 88.72%,respectively).At the genus level,the dominant bacteria were Bacteroides(35.42%)and Faecalibacterium(10.12%)in the maternal gut microbiota,Lactobacillus(69.10%)and Bifidobacterium(11.30%)in the vaginal microbiota,and Lactobacillus(79.81%)and Pseudomonas(3.23%)in the vernix caseosa microbiota.The dominant bacterium in the neonatal meconium was Escherichia in the two batches of samples(55.21%and 31.18%,respectively).Conclusion·The α diversity of maternal gut microbiota is higher than that of vaginal microbiota and neonatal meconium microbiota,and it is higher in neonatal vernix caseosa than that in meconium microbiota.The Firmicutes is the predominant phylum in the maternal late-pregnancy gut microbiota,vaginal microbiota,and neonatal vernix microbiota.Lactobacillus is the predominant genus in both maternal vaginal and neonatal vernix caseosa microbiota.Proteobacteria in phylum and Escherichia in genus are predominant in meconium microbiota.The microbiota composition is similar in vernix caseosa at different body sites,but there are differences between the vernix caseosa microbiota and meconium microbiota.

Objective To develop a high performance liquid chromatography-tandem mass spectrometry(HPLC-MS/MS)method for simultaneous determination of five flavonoids in Ganmao'an granules(GMA).Methods Chromatographic separation was achieved on a Kromasil C18 Column(150 mm×4.6 mm,5 μm,100 ?),which was eluted with methanol(A)-0.1％formic acid(B)at the flow rate of 1.0 ml/min.The gradient condition was as follows:0-20 min,35％A,and 20-40 min,45％A.The column temperature was 25 ℃.Analytes were detected using a triple quadrupole tandem mass spectrometer equipped with an electrospray ionization source in the negative ion scanning.The multiple reaction monitoring mode was used for qualitative analysis.For each flavonoid,two precursor ion/product ion transitions were chosen:lutin m/z 609.1→300.1,hyperin and isoquercitrin m/z 463.0→300.1,quercetin m/z 301.0→151.0,luteolin m/z 285.0→132.9.Results Five flavonoids showed the good relationships within their own concentration ranges(correlation coefficient r>0.999 1),whose average recoveries were in the range of 100.63％-102.81％with RSDs of 0.67％-2.07％.The content results of rutin,hyperoside,isoquercetin,quercetin,and luteolin in 10 batches of GMA were 32.23-479.83,0.291-1.825,11.44-20.54,6.32-18.41,3.46-6.51 μg/g,respectively.Conclusion The results indicated that the developed method was sensitive,accurate and could provide excellent specificity for simultaneous determination of five flavonoids in GMA.

Objective To explore the pharmacokinetic properties of curcumin nano emulsion and its pharmacodynamic effects on hyperlipidemia in rats. Methods The method for determination of curcumin was established by HPLC-MS. The pharmacokinetics characteristics of curcumin nano emulsion oral administration system were investigated. SD rats were used as model animals to establish hyperlipidemia animal models, and the pharmacodynamic effects of curcumin nano emulsion on hyperlipidemia induced by high fat diet was preliminarily investigated. Results The results of pharmacokinetic studies in vivo showed that the relative bioavailability of curcumin nano emulsion was 313.47% with bulk drug group as the reference preparation. The relative bioavailability of curcumin nano emulsion was 279.52 % with tablets as reference preparation. C_max of curcumin nano emulsion group was 201.48 % of that of bulk drug group and 193.02 % of that of tablet group, and had higher MRT value (183.52 % of that of bulk drug group and 154.21 % of that of tablet group) than bulk drug group and tablet group. Pharmacodynamics research results showed that curcumin nano emulsion oral administration system could significantly reduce the levels of triglyceride and LDL-c in serum of model rats, and relieve liver lipid deposition and liver injury caused by high-fat diet in model animals. Conclusion The oral administration system of curcumin nano emulsion could effectively improve the bioavailability of curcumin, which has a good hypolipidemic effect. It also could control the weight gain of hyperlipidemia rats and improve the changes of liver coefficient caused by lipid metabolism disorder.
