ObjectiveTo evaluate the pregnancy outcomes of assisted reproductive technology （ART） in women with a history of thyroid cancer who retained fertility intentions after completing cancer treatment. MethodsA retrospective analysis was performed on 61 patients with a history of thyroid cancer who underwent in vitro fertilization/intracytoplasmic sperm microinjection and embryo transfer （IVF/ICSI-ET）. These patients were included as the case group. A total of 122 non-cancer patients who received ART during the same period were selected as the control group using 1∶2 matching based on age and oocyte retrieval time. Baseline characteristics， outcomes of the first ART cycle， and cumulative pregnancy outcomes were compared between the two groups. ResultsThere was no significant difference in the basic data， the total amount of gonadotropin （Gn） and the days of use between the case group and the control group （P>0.05）. However， the case group had significantly fewer retrieved oocytes， mature oocytes （MII）， lower fertilization and cleavage rates， and fewer transferable and high-quality embryos， as well as fewer embryos transferred during the first cycle （P < 0.05）. However， there was no significant difference in the rate of first embryo implantation and first clinical pregnancy between the two groups （P>0.05）. In the analysis of cumulative outcomes， the two groups did not show statistically significant differences in the cumulative pregnancy rate， clinical pregnancy rate per transfer cycle， the number of oocyte retrieval cycles required per live birth， the number of embryo transfer cycles required per live birth， and the number of embryos used for each live birth （P>0.05）. However， the cumulative live birth rate was significantly lower in the case group compared to the control group （P=0.005）. ConclusionAfter treatment for thyroid cancer， when ART is used to help pregnant women， the pregnancy outcome is comparable to that of women without tumors. Individualized reproductive management and timely fertility preservation strategies are recommended to optimize reproductive outcomes in this population.

OBJECTIVE To establish a combined pharmacokinetic(PK)-pharmacodynamic(PD)model for knee osteoarthritis(KOA)of crossbow drug microemulsion multi-components(benzoylmesaconine,benzoylhypacoitine,mesaconitine,periplocin,neo-chlorogenic acid,vanillic acid,chlorogenic acid),and elucidate the dynamic changes in the KOA rats and the interrelation with the e-lapsed efficacy of the drug.METHODS A KOA rat model was induced by 4%papain;the PK process of crossbow medicine microe-mulsion components in rat synovial fluid was analyzed by UPLC to establish a PK model;the contents of MMP-3,MMP-13,TNF-α and IL-1β in KOA rats at different time points after administration were determined by ELISA analysis to establish a PD model;Phoe-nix WinNonlin software was used to fit the PK and PD data to obtain a PK-PD model.RESULTS PK results showed that the multi-components of the microemulsion were slowly absorbed in the joint cavity and gradually reached the peak value within 3-5 h.The Cmax of benzoylmesaconine,benzoylhypacoitine mesaconitine,periplocoside,neochlorogenic acid,vanillic acid and chlorogenic acid were 1.23,1.48,1.62,4.67,0.93,1.25 and 2.35 μg·mL-1,respectively;the area under the drug-time curve(AUC0-11)was 2.58,4.04,3.54,12.15,2.51,2.41 and 4.11 h·μg·mL-1,respectively.PD results showed that at different time points after adminis-tration,the contents of MMP-3,IL-1β,TNF-α,and MMP-13 decreased to varying degrees,among which MMP-3 decreased insig-nificantly,with significant differences only at 6 h;the contents of the remaining IL-1β,TNF-α,and MMP-13 decreased significantly(P<0.05,P<0.01),and showed the phenomenon of lagged efficacy;the PK-PD binding model showed that the drug concentration of the multi-component drug in the crossbow medicine microemulsion could be well fitted with its drug efficacy data.CONCLUSION The established PK-PD binding model can predict the drug efficacy changes after administration,and provides a corresponding refer-ence for the crossbow medicine microemulsion treatment of KOA.

Objective:To compare the effect of metal prefabricated crowns and 3M350 universal resin on the dental caries of deciduous teeth.Methods:Retrospective analysis was performed on the clinical data of 89 children with proximal molar caries restoration admitted to Nantong Stomatological Hospital from January 2020 to January 2022. According to treatment methods, they were divided into observation group (metal prefabricated crowns restoration treatment, 49 cases of 49 teeth) and control group (3M350 universal resin restoration treatment, 40 cases of 40 teeth). The repair effect, occlusal function, periodontal index, treatment satisfaction and complications were compared.Results:The success rate of repair in the observation group (93.88%, 46/49) was higher than that in the control group (77.50%, 31/40), and the difference was statistically significant ( P<0.05). The maximum biting force and masticatory efficiency of the two groups after treatment were higher than those before treatment, and the observation group was higher than the control group, and the difference was statistically significant (all P<0.05). Comparison of periodontal indexes between the experimental and control groups comparison of probing depth (PD), plaque index (PLI), and bleeding index (BI) between the two groups before treatment, the differences were not statistically significant (all P>0.05); after treatment, PD, PLI, and BI were lower in both groups, and lower in the experimental group (all P<0.05). The total satisfaction of the observation group (87.76%, 43/49) was higher than that of the control group (65.00%, 26/40), and the difference was statistically significant ( P<0.05). The incidence of complications in the observation group (6.12%, 3/49) was lower than that in the control group (22.50%, 9/40), and the difference was statistically significant ( P<0.05). Conclusions:Compared with 3M350 general purpose resin, metal prefabricated crowns has better repairing effect and lower complication rate on adjacent caries of deciduous teeth, so it can be widely used in clinic.

To investigate the clinical value of endoscopic ultrasound-guided puncture drainage in the treatment for liver abscess and abdominal and pelvic abscess with difficulty in conventional puncture drainage. Data of 12 such patients in the Second Affiliated Hospital of Soochow University from January 2015 to November 2023 were retrospectivly analyzed. Results showed liver abscess in 4 cases, abdominal and pelvic abscess in 8 cases. All patients had fever with varying degrees of abdominal pain. Twelve patients with liver abscess and abdominal and pelvic abscess received 13 times of endoscopic ultrasound-guided puncture (1 patient with a large abdominal and pelvic cyst complicated with infection received transgastric and transrectal puncture of 2 times). The puncture needle was successfully penetrated into the pus cavity. Four patients with liver abscess underwent endoscopic ultrasound-guided suction and irrigation, and the abscess was almost completely aspirated. Seven patients with abdominal and pelvic abscess underwent endoscopic ultrasound-guided suction and irrigation, of which 5 cases were almost completely aspirated, and 2 cases had poor drainage effect due to the viscous pus (1 case returned to normal temperature after anti-infection treatment; 1 case had recurrent fever after the operation, and septic shock and death occurred 2 weeks after the operation). A patient with recurrent abdominal and pelvic sclerosis after the operation had multiple abscesses in the abdomen and pelvis, and percutaneous CT-guided drainage was performed for abdominal abscess, but the fever was still repeated. Endoscopic ultrasound-guided balloon dilation plus double pig tail and nasobiliary duct drainage were performed. The patient's temperature returned to normal and abdominal pain was relieved 48 hours after the operation. The total effective rate of abscess drainage was 83.3% (10/12), and the effective rate of suction combined with irrigation for abscess drainage was 81.8% (9/11), and no operation-related complications were observed in all patients. After 3 months of follow-up, no recurrence occurred in 10 patients with effective drainage of abscess, and abscess was self-absorbed in 1 patient with pelvic abscess without effective drainage and no recurrence was observed. Endoscopic ultrasound-guided puncture drainage is of certain clinical value for some liver abscesses and abdominal and pelvic abscesses that are difficult to be drained by conventional puncture, and can reduce the secondary trauma caused by surgical operations.

Objective:To examine the impact of the"outpatient+inpatient"bundled integrated payment reform on the utilization of health services for patients with ordinary tuberculosis,and to evaluate its effectiveness in resource allocation and cost containment.Methods:Based on the Andersen model,clinical and health insurance data from a city in Hebei Province were analyzed.An empirical study was conducted on 5 656 patients using Ordinary Least Squares(OLS)regression and Propensity Score Matching(PSM)to assess outpatient and inpatient service utilization and related costs.Results:Patients in the post-reform group showed a significant increase in outpatient visits and outpatient costs(an average increase of approximately 4.809 visits and 266.368 yuan,respectively,P<0.001),while inpatient visits,inpatient costs,and total medical costs significantly decreased(reductions of approximately 0.302 visits,3 638.647 yuan,and 3 372.279 yuan,respectively,P<0.001).Conclusion:The bundled integrated payment model effectively promotes outpatient service utilization,optimizes inpatient resource allocation,and reduces medical costs.However,the sharp increase in outpatient workload may pose a risk of overutilization.Recommendations:Future initiatives should establish a dynamic monitoring and evaluation system that emphasizes both service quality and clinical outcomes in outpatient and inpatient settings.Furthermore,refining incentive and regulatory mechanisms is essential to ensure that cost control measures do not compromise medical quality and patient safety.
