Objective To observe the effects of Baishile Capsules on neonatal neuronal activity and synaptic plasticity in hippocampus of depression model rats;To explore its mechanism of antidepressant.Methods Totally 32 SD rats were randomly divided into blank group,model group,fluoxetine group(5.4 mg/kg)and Baishile Capsules group(2.88 g/kg),with 8 rats in each group.The depression rat model was established by chronic unpredictable mild stress and single cage feeding,and drugs were administered at the same time as modeling for 21 consecutive days.Forced swimming test and open field test were used to evaluate the depressive-like behavior of rats,Golgi staining was used to observe the synaptic morphology of hippocampal neurons,and immunofluorescence was used to detect the positive expressions of BrdU/GABA-B,BrdU/c-fos,BrdU/GAP-43,BrdU/MAP-2 and CXCR4 in hippocampal tissue.Results Compared with the blank group,the immobility time of forced swimming experiment in the model group increased,and the horizontal and vertical time of open field experiment decreased significantly(P<0.01);the hippocampal neurons dendrites and dendritic spines atrophied,the density decreased,the branches became shorter,synaptic structure becomes blurred,and the longest and total lengths of synaptic branches significantly decreased(P<0.01);the positive expressions of GABA-B,c-fos,GAP-43 and MAP-2 proteins in hippocampal neonatal neurons decreased(P<0.05,P<0.01),and the expression of CXCR4 in hippocampal tissue decreased significantly(P<0.01).Compared with the model group,the immobility time of the forced swimming experiment in fluoxetine group and Baishile Capsules group significantly reduced,and the horizontal and vertical activity time of the open field experiment significantly increased(P<0.01);the number of dendritic spines in hippocampal neurons increased,synaptic damage improved,and the length of the longest and total branches of synapses significantly increased(P<0.01);the positive expressions of GABA-B,c-fos,GAP-43 and MAP-2 in hippocampal neonatal neurons significantly increased(P<0.05,P<0.01),and the positive expression of CXCR4 in hippocampal tissue significantly increased(P<0.01).Conclusion Baishile Capsules can regulate hippocampal synaptic plasticity and nerve regeneration by improving the activity and function of hippocampal neonatal neurons in depression model rats,exerting antidepressant effects.

Objective To investigate the distribution and antimicrobial resistance profiles of clinically isolated Haemophilus influenzae and Moraxella catarrhalis in hospitals across China from 2015 to 2021,and provide evidence for rational use of antimicrobial agents.Methods Data of H.influenzae and M.catarrhalis strains isolated from 2015 to 2021 in CHINET program were collected for analysis,and antimicrobial susceptibility testing was performed by disc diffusion method or automated systems according to the uniform protocol of CHINET.The results were interpreted according to the CLSI breakpoints in 2022.Beta-lactamases was detected by using nitrocefin disk.Results From 2015 to 2021,a total of 43 642 strains of Haemophilus species were isolated,accounting for 2.91％of the total clinical isolates and 4.07％of Gram-negative bacteria in CHINET program.Among the 40 437 strains of H.influenzae,66.89％were isolated from children and 33.11％were isolated from adults.More than 90％of the H.influenzae strains were isolated from respiratory tract specimens.The prevalence of β-lactamase was 53.79％in H.influenzae strains.The H.influenzae strains isolated from children showed higher resistance rate than the strains isolated from adults.Overall,779 strains of H.influenzae did not produce β-lactamase but were resistant to ampicillin(BLNAR).Beta-lactamase-producing strains showed significantly higher resistance rates to these antimicrobial agents than the β-lactamase-nonproducing strains.Of the 16 191 M.catarrhalis strains,80.06％were isolated from children and 19.94％isolated from adults.M.catarrhalis strains were mostly susceptible to both amoxicillin-clavulanic acid and cefuroxime,evidenced by resistance rate lower than 2.0％.Conclusions The emergence of antibiotic-resistant H.influenzae due to β-lactamase production poses a challenge for clinical anti-infective treatment.Therefore,it is very important to implement antibiotic resistance surveillance for H.influenzae and guide rational antibiotic use.All local clinical microbiology laboratories should actively improve antibiotic susceptibility testing and strengthen antibiotic resistance surveillance for H.influenzae.

Objective:To explore the clinicopathological characteristics and prognosis of fumarate hydratase-deficient uterine leiomyoma (FH-dUL).Methods:Clinical data and follow-up information for 117 patients with FH-dUL diagnosed through surgical pathology and immunohistochemistry in the First Affiliated Hospital of Nanjing Medical University from January 2020 to December 2024, were collected. A control group of 130 patients with common uterine leiomyomas was also included. The differences between the two groups in clinical, imaging, and pathological characteristics were compared. Additionally, recurrence rates, fertility outcomes for FH-dUL patients, and the incidence of renal cancer in FH germline mutation carriers were monitored.Results:(1) Comparison of clinicopathological characteristics: the median age of 117 FH-dUL patients was 35 years, and the median age at first diagnosis of uterine leiomyomas was 29 years, both significantly younger than the control group (41 and 36 years; both P<0.01). The FH-dUL group showed significantly higher incidences of uterine myomectomy, multiple leiomyomas, diffusion restriction on pelvic magnetic resonance imaging diffusion weighted imaging, and typical pathological features (candelabra-like vessels, bizarre nuclei, cytoplasmic eosinophilic globules, perinuclear halo, cellular atypia) and higher ultrasound blood flow score (all P<0.05). Of the 30 FH-dUL patients who underwent genetic testing, 9 had germline mutations, 3 had somatic mutations, and 6 had mutations of unclear origin. Among the 9 FH gene germline mutation patients, 2 had already developed renal cell carcinoma. (2) Recurrence analysis: among the 56 patients who underwent uterine myomectomy, 22 (39.3%, 22/56) experienced recurrence during follow-up, compared to 12 (21.8%, 12/55) of the 55 patients in the control group, the difference between the two groups was statistically significant ( P=0.046). Multivariate binary logistic regression analysis showed that cellular leiomyomas ( OR=9.489, 95% CI: 1.740-51.755; P=0.009) and multiple uterine leiomyomas ( OR=10.709, 95% CI: 1.354-84.683; P=0.025) were significant risk factors for recurrence in FH-dUL. (3) Fertility analysis: among the 66 FH-dUL patients who underwent fertility-preserving surgery, 16 had the intention to have fertility desire, only 2 (2/16) completed their fertility plans during follow-up. Conclusions:Clinicopathological features and imaging features help to differentiate FH-dUL from common type uterine fibroids, but lack specificity, and the diagnosis of FH-dUL is based on immunohistochemistry. The recurrence rate after resection of FH-dUL is high, and cellular and multiple leiomyomas are important predictors of recurrence. It is crucial to perform genetic testing, genetic counseling, drug treatment to prevent recurrence, fertility guidance, and long-term comprehensive management after surgery for FH-dUL management.

Objective:To observe the effects and safety of dienogest on the volume and symptoms of ovarian endometrioma (OMA).Methods:The clinical data of 75 patients with OMA who underwent treatment with dienogest (2 mg/day) at the First Affiliated Hospital of Nanjing Medical University from July 1st 2020 to March 31st 2024 were retrospectively analysed, mainly comparing the changes in the volume of OMA and the visual analogue scale (VAS) scores of endometriosis-related pain before and after the treatment, as well as observing the changes in the blood biological indicators, liver and kidney function, coagulation function and changes in breast.Results:The median cyst volumes of the OMA patients at 3, 6 and 12 months of dienogest treatment were 13.21 cm 3 (volume reduction rate: 36.00%), 8.33 cm 3 (volume reduction rate: 56.00%) and 4.10 cm 3 (volume reduction rate: 77.62%), respectively, which were all significantly decreased from the pre-treatment period (all P<0.05). The VAS scores of pain of the OMA patients at 3, 6 and 12 months of dienogest treatment all were 0 mm. Blood cancer antigen 125 (CA 125) and cancer antigen 19-9 (CA 19-9) levels decreased progressively during treatment (all P<0.05). There were no statistical differences in the coagulation indexes, liver and kidney function indexes of the patients during dienogest treatment compared with those before treatment (all P>0.05). During the follow-up period, there were a few patients with changes in the growth sites or lesion category of the breast nodules, but there were no occurrence of breast cancer or precancerous lesions. Conclusion:Dienogest is effective in reducing OMA volume and alleviating endometriosis-related pain with few adverse effects.

Objective:To retrospectively analyze the treatment status of tyrosine kinase inhibitors (TKI) in newly diagnosed patients with chronic myeloid leukemia (CML) in China.Methods:Data of chronic phase (CP) and accelerated phase (AP) CML patients diagnosed from January 2006 to December 2022 from 77 centers, ≥18 years old, and receiving initial imatinib, nilotinib, dasatinib or flumatinib-therapy within 6 months after diagnosis in China with complete data were retrospectively interrogated. The choice of initial TKI, current TKI medications, treatment switch and reasons, treatment responses and outcomes as well as the variables associated with them were analyzed.Results:6 893 patients in CP ( n=6 453, 93.6%) or AP ( n=440, 6.4%) receiving initial imatinib ( n=4 906, 71.2%), nilotinib ( n=1 157, 16.8%), dasatinib ( n=298, 4.3%) or flumatinib ( n=532, 7.2%) -therapy. With the median follow-up of 43 ( IQR 22-75) months, 1 581 (22.9%) patients switched TKI due to resistance ( n=1 055, 15.3%), intolerance ( n=248, 3.6%), pursuit of better efficacy ( n=168, 2.4%), economic or other reasons ( n=110, 1.6%). The frequency of switching TKI in AP patients was significantly-higher than that in CP patients (44.1% vs 21.5%, P<0.001), and more AP patients switched TKI due to resistance than CP patients (75.3% vs 66.1%, P=0.011). Multi-variable analyses showed that male, lower HGB concentration and ELTS intermediate/high-risk cohort were associated with lower cytogenetic and molecular responses rate and poor outcomes in CP patients; higher WBC count and initial the second-generation TKI treatment, the higher response rates; Ph + ACA at diagnosis, poor PFS. However, Sokal intermediate/high-risk cohort was only significantly-associated with lower CCyR and MMR rates and the poor PFS. Lower HGB concentration and larger spleen size were significantly-associated with the lower cytogenetic and molecular response rates in AP patients; initial the second-generation TKI treatment, the higher treatment response rates; lower PLT count, higher blasts and Ph + ACA, poorer TFS; Ph + ACA, poorer OS. Conclusion:At present, the vast majority of newly-diagnosed CML-CP or AP patients could benefit from TKI treatment in the long term with the good treatment responses and survival outcomes.
