ObjectiveTo investigate the correlation between neutrophil-to-lymphocyte ratio （NLR）， platelet-to-lymphocyte ratio （PLR）， systemic immune-inflammation index （SII） and the severity of intrauterine adhesions （IUA）. MethodsThe retrospective study included 380 patients who underwent transcervical resection of adhesions （TCRA） from December 2019 to March 2025. Based on the American Fertility Society （AFS） classification， patients were divided into mild （n=61）， moderate （n=225）， and severe （n=94） groups. NLR， PLR， and SII were calculated from preoperative blood tests. Statistical analyses included Kruskal-Wallis test and ordinal Logistic regression. ResultsNLR， PLR， and SII were significantly higher in the severe IUA group compared to the mild group （P<0.05）， with SII showing the strongest predictive ability （OR=1.004， P=0.001）. The number of intrauterine procedures was an independent risk factor （OR=1.27/level， P=0.016）. The predictive model ［Logit（P）=-0.676+0.241×operation times+0.004×SII］ effectively identified severe IUA cases. ConclusionInflammatory markers （particularly SII） are correlated with IUA severity and may serve as non-invasive tools for clinical assessment.

Objective To investigate the effect of Pericarpium Citri Reticulatae on changes of the intestinal absorption of ginsenoside components in Yi Gong San based on the rat model of spleen deficiency and whether its effect is related to the exocytosis of P-gp protein.Methods The group design included the P-gp protein agonist rifampicin and the inhibitor verapamil,and 36 SD rats were randomly divided into a blank control group(6 rats)and a model group(30 rats),and then subcutaneously injected with rifampicin to establish a model of splenic deficiency,and then the model group was divided into the Yigong San fullparty(Y)group,the lack of Pericarpium Citri Reticulatae(Y-C)group,the YiGong San combined with rifampin(Y+R)group,the lack of Pericarpium Citri Reticulatae combined with verapamil(Y-C+V)group and the lack of Pericarpium Citri Reticulatae combined with rifampin(Y-C+R)group,Ginsenoside Rb1,ginsenoside Re and ginsenoside Rg1 were used as the index components in an in situ unidirectional intestinal perfusion test,and HPLC-MS was used to determine the content of the index components and to calculate the kinetic parameters of intestinal absorption,the effective permeability coefficient(Peff)and the absorption rate constant(Ka).Results Compared with group Y,Peff of ginsenoside Rb1 and Re were significantly lower in Y-C at multiple perfusion sessions,and Peff and Ka of ginsenoside Rb1,ginsenoside Re,and ginsenoside Rg1 were lower in Y+R at multiple perfusion sessions,suggesting that Pericarpium Citri Reticulatae promotes the intestinal absorption of ginsenoside Rb1 and ginsenoside Re and that this effect is related to the activity of the P-gp protein,but failed to change the intestinal absorption of ginsenoside Rg1.The P-gp protein inhibitor verapamil significantly increased the Peff of ginsenoside Rb1 and Re in the Y-C+V compared with the Y-C,while the P-gp protein agonist rifampicin significantly decreased the Peff and Ka of ginsenoside Rb1,ginsenoside Re,and ginsenoside Rg1 in the Y-C+R in multiple perfusion sessions.The significant decrease in Peff and Ka at multiple perfusion times suggests that ginsenoside Rb1,ginsenoside Re,and ginsenoside Rg1 may be substrates for P-gp proteins in the absence of Pericarpium Citri Reticulatae intervention.Conclusion Pericarpium Citri Reticulatae promotes the intestinal absorption of ginsenoside Rb1 and ginsenoside Re by exerting a verapamil-like effect that inhibits the activity of P-gp proteins in Yi Gong San.

Objective To explore the value of dual energy CT imaging in the diagnosis of gouty tophus deposition.Methods Sixty-five cases of patients with gout treated in this hospital between December 2012 to December 2015 were selected.Another 65 cases of patients(rheumatoid arthritis,degenerative osteoarthritis and unexplained leg pain) were selected as control group.The re sults of dual energy CT imaging between two group were compared.Three experienced clinicians who didn't understand the imaging results were selected.They had a medical history and physical examination in patients with gout.The differences between clinical evaluation and imaging results were compared.Results Dual energy CT imaging showed that there were no tophi deposition in con trol group;the topi deposition in wrist joint,knee joint and ankle joint were 6.06％oo (33/34),100.00％ (22/22) and 96.49％ (55/57) in gout group.Dual energy CT imaging detected a total of 545 parts of tophus deposition.It was 4.36 times of the result of clinical evaluation(125 parts).Conclusion Dual energy CT imaging shows the advantages of simple noninvasive,high accuracy and low rate of misdiagnosis in diagnosing gout nodules.

Objective:To compare the effectiveness of proximal femoral nail antirotation (PFNA) with intertrochanteric antegrade nail (InterTAN) in the treatment of intertrochanteric fractures in the elderly. Methods:A retrospective study of 62 elderly patients with intertrochanteric fractures who received two operation methods from Sep 2014 to May 2016 was done. There were 28 patients in PFNA group, and 34 patients in InterTAN group. The operation time, blood loss in operation, hospitalization time, healing time, and Harris hip joint functional score were compared and analyzed. Results:Operation time and the amount of intraoperative blood loss in PFNA group were less than that in InterTAN group. Hospitalization time,fracture healing time and Harris hip joint functional score after ten months had no significant difference between the two groups. And 59 cases in total were followed up with an average of 11.5 months (from 9 to 16 months) . In PFNA group, 27 patients were followed up, and one patient was lost to follow up, who died because of chronic renal insufficiency. The rest 26 patients all achieved bony union (including one case of hip versus) . At follow-up 9 months, hip joint function was excellent in 18 cases, good in 6, fair in 2, bad in 1, and the excellent-good rate was 88.9%. In InterTAN group,32 patients were followed up,and two cases were lost to follow up. In followed-up cases, there was one patient who was no healing of fracture. After hip arthroplasty, this patient got recovery. The hip joint function was excellent in 21 cases, good in 7, fair in 3, and bad in 1. The differences between the two groups were not statisticaly significant. Conclusion:Both PFNA and InterTAN can treat intertrochanteric fractures in the elderly with good result,but PFNA has obvious advantages over InterTAN on less hemorrhage and operation time.
