Objective:To establish a rapid detection method based on matrix-assisted laser desorption ionization time-of-flight mass spectrometry(MALDI-TOF MS)for drug resistance of Carbapenem-resistant Enterobacteriaceae(CRE),so as to provide basis for enhancing clinically diagnostic effect.Methods:A total of 120 suspected CRE strains that were isolated from the clinical laboratory of Jiading District Central Hospital Affiliated to Shanghai University of Medicine&Health Sciences during October 2023 and September 2024 were collected,and the experimental detection of 44 strains was finally completed.The 44 suspected CRE bacterial strains were all from hospitalized patients.A rapid detection protocol based on the MALDI-TOF MS platform was initially established and improved,and experimental detection was carried out using the fully automatic rapid microbial mass spectrometry detection system(VITEK MS).The results of identification review and antimicrobial susceptibility test(AST)for VitEK-2 Compact strain was used as the reference standard.The screening results and detection efficacy of two kinds of detection methods were compared.Results:In the 44 suspected CRE strains,31 CRE strains were screened out by MALDI-TOF MS detection,and 31 CRE stains were screened out by VITEK-2 Compact recheck detection.In them,one strain of Enterobacter cloacae was confirmed as negativity by the MALDI-TOF MS test,but it was confirmed as CRE by the VITEK-2 Compact test.One strain of Klebsiella pneumoniae was confirmed as positivity by the MALDI-TOF MS test,but it was confirmed as mediator for carbapenem drugs by the VITEK-2 Compact test.The tested results of VITEK-2 Compact was used as standard,the results of four-grid table(2×2 contingency table)statistical method indicated that the sensitivity,specificity,accuracy rate and Youden index(R)of MALDI-TOF MS were respectively 96.7%,92.3%,100%and 89.1%.Conclusion:The rapid detection method based on the MALDI-TOF MS platform for CRE drug resistance has simple operation process and high accuracy rate,which can provide a basis for the application of targeted antibacterial drugs at early stage.

OBJECTIVE: To explore the mechanism of acupuncture on improving ovarian hypofunction in aged rats from two perspectives: the overall regulation of the hypothalamic-pituitary-ovarian (HPO) axis and the local ovarian follicle stimulating hormone (FSH)/cyclic adenosine monophosphate (cAMP) signaling pathway. METHODS: Six 3-month-old female SPF-grade Sprague-Dawley (SD) rats were selected as the blank group. Another twelve 9-month-old female SD rats were randomly divided into a model group and an acupuncture group, with six rats in each. The acupuncture group received acupuncture at "Baihui" (GV20), "Guanyuan" (CV4), and bilateral "Ciliao" (BL32) for 20 min per session, once every other day, for a total of 10 sessions. Vaginal smear tests were performed daily to observe the estrous cycle of the rats. Ovarian morphology was observed using HE staining, and follicles at various stages were counted. ELISA was used to detect levels of serum FSH, luteinizing hormone (LH), estradiol (E₂), anti-müllerian hormone (AMH), hypothalamic gonadotropin-releasing hormone (GnRH), pituitary FSH and LH, and ovarian cAMP. Immunohistochemistry and Western blot were used to detect the protein expression of ovarian cAMP protein kinase catalytic subunit, FSH receptor (FSHR), and P450. Real-time quantitative PCR was used to measure mRNA expression levels of FSHR and P450 in ovarian tissue. RESULTS: Compared with the blank group, the model group showed an increased rate of estrous cycle disorder (P<0.01), reduced granulosa cell layers with blurred boundaries and disordered arrangement, decreased numbers of developing follicles at all stages, and increased numbers of atretic follicles (P<0.01); the serum levels of FSH and LH were increased (P<0.01), while E₂ and AMH levels were decreased (P<0.01); the hypothalamic GnRH and pituitary FSH and LH levels were elevated (P<0.01), and ovarian cAMP level was decreased (P<0.01); the positive expression and protein expression of ovarian P450, cAMP protein kinase catalytic subunit, and FSHR were reduced (P<0.01), and ovarian FSHR and P450 mRNA expression was decreased (P<0.01). Compared with the model group, the acupuncture group showed a reduced rate of estrous cycle disorder (P<0.01), clear granulosa cell margins, increased numbers of primordial and secondary follicles, and decreased numbers of atretic follicles (P<0.01); the serum FSH and LH levels were decreased (P<0.01, P<0.05), while E₂ and AMH levels were increased (P<0.05, P<0.01); the hypothalamic GnRH and pituitary FSH and LH levels were decreased (P<0.01, P<0.05), and ovarian cAMP level was increased (P<0.01); the positive expression and protein expression of ovarian P450, cAMP protein kinase catalytic subunit, and FSHR were elevated (P<0.01), and ovarian FSHR and P450 mRNA expression was increased (P<0.01). CONCLUSION Acupuncture could delay ovarian hypofunction in aged rats, possibly through regulating the HPO axis and the FSH/cAMP signaling pathway.

Objective To explore the early predictors of macrolide-unresponsive Mycoplasma pneumoniae pneumonia(MUMPP)and construct a nomogram prediction model.Methods The clinical data of 159 chil-dren with Mycoplasma pneumoniae pneumonia(MPP)admitted to the hospital from January 2023 to Februar-y 2024 were retrospectively collected.According to the time of admission,they were divided into modeling group(112 cases)and validation group(47 cases).The modeling group was further divided into MUMPP group(51 cases)and MPP group(61 cases)according to the drug response.The clinical data and laboratory indexes of each group were compared.The independent predictors of MUMPP were analyzed by univariate and multivariate analysis,and a nomogram prediction model was constructed.Receiver operating characteristic(ROC)curve,area under the curve(AUC),decision curve,calibration curve and Hosmer-Lemeshow goodness of fit test were used to evaluate the discrimination,clinical practicability and calibration of the model.Results The systemic immune inflammation index(SII),C-reactive protein(CRP)/albumin(ALB)and D-dimer were independent influencing factors of MUMPP(P＜0.05).The AUC was 0.938(95％CI 0.890-0.986)in the modeling group and 0.912(95％CI 0.832-0.992)in the validation group.x2 was 3.768 and P was 0.877 in Hosmer-Lemeshow goodness-of-fit test,threshold probability between 5％and 99％had high net clinical benefit.Conclusion The nomogram prediction model established by SII,CRP/ALB and D-dimer has good prediction accuracy and high clinical application value for children with MUMPP.

ObjectiveTo compare the effects of different doses and withdrawal time of 4-vinylcyclohexene diepoxide （VCD） on the reproductive endocrine levels of female rats， and to explore the effective， stable， and safe dosage of VCD for constructing a premature ovarian insufficiency （POI） rat model. MethodSD rats with regular estrous cycles were randomly divided into three groups： blank group， low-dose VCD group （80 mg·kg^-1·d^-1）， and high-dose VCD group （160 mg·kg^-1·d^-1）， with 24 rats in each group. After drug intervention， samples were collected on the 15th day （D15） and the 45th day （D45） after intervention. The general condition， rate of estrous cycle disturbance， serum hormone levels， ovarian histomorphology， follicle count， pregnancy outcome， and the protein and mRNA expression of transforming growth factor （TGF）-β and Smad2/3 were assessed. ResultCompared with the blank group， the low-dose VCD group showed no significant differences in the rate of estrous cycle disturbance or serum follicle-stimulating hormone （FSH）， luteinizing hormone （LH）， and estradiol （E₂） levels. Ovarian tissue was damaged. Specifically， the number of primordial and primary follicles decreased on D15 （P<0.01）， and the number of secondary follicles （P<0.01） and antral follicles （P<0.05） further decreased on D45. The litter number decreased on D15 （P<0.05）， but there was no significant difference on D45. Furthermore， TGF-β protein levels increased on D15 （P<0.05） and D45 （P<0.01）. The Smad2/3 levels increased on D45 （P<0.01）， and TGF-β and Smad2/3 mRNA levels increased on D45 （P<0.05）. Compared with the results in the blank group， the disturbance rate of the estrous cycle increased on D45 in the high-dose VCD group （P<0.01）. The serum of FSH and LH increased （P<0.01）， while E₂ decreased （P<0.05）. Ovarian tissue was damaged， and the downward trend of follicles at all levels was similar to that in the low-dose VCD group. The litter number significantly decreased on D15 and D45. TGF-β and Smad2/3 protein levels increased （P<0.05，P<0.01）， and TGF-β mRNA increased on D45 （P<0.05）. ConclusionHigh-dose VCD is an ideal method for constructing a POI rat model， being effective， stable， and safe.
