Objective:To study the diagnostic value and correlation of contrast-enhanced ultrasound time-intensity curve in the main pathological features of cervical cancer.Methods:From August 2021 to August 2023, 100 patients with cervical cancer and 100 patients with benign cervical tumors examined in Dingzhou People’s Hospital were selected for study. Patients with benign cervical tumors were included in the control group, and patients with cervical cancer were included in the observation group.The two groups of patients were examined by PHILIPS EPIQ7 C color Doppler ultrasound diagnostic instrument and PHILIPS EPIQ5 color Doppler ultrasound diagnostic instrument to obtain the quantitative parameters of the time-intensity curve of the two groups. The bivariate Spearman correlation test was used to analyze the main pathological features of cervical cancer patients (lesion diameter, pathological type, vascular invasion, lymph node metastasis, differentiation degree, clinical stage) and the correlation between radiotherapy and chemotherapy and the acquisition of time-intensity curve. The receiver operating characteristic curve (ROC) was drawn to analyze the diagnostic value of the time-intensity curve.Results:The time to peak (TTP) value of the cervical cancer group was lower than that of the control group, and the peak intensity (PI) and maximum peak intensity ratio (PI/PIc) values were higher than those of the control group, the differences were statistically significant ( P<0.05). Compared with patients with non-squamous cell carcinoma, vascular invasion < 1/2, no lymph node metastasis, moderate to high differentiation, stage I-II, and after radiotherapy and chemotherapy, patients with squamous cell carcinoma, vascular invasion ≥ 1/2, lymph node metastasis, low differentiation, stage III-IV, and before radiotherapy and chemotherapy had lower TTP values, higher PI and PI/PIc values, and the differences were statistically significant ( P<0.05). Pathological type, vascular invasion, lymph node metastasis, differentiation degree and clinical stage were negatively correlated with TTP, and positively correlated with PI and PI/PIc ( P<0.05) .Chemoradiotherapy was positively correlated with TTP, and negatively correlated with PI and PI/PIc ( P<0.05). The sensitivity and specificity of combined detection of time intensity curve were higher than those of TTP, PI, PI/Ic, area under curve (AUCTC) and mean transit time (MTT), and the differences were statistically significant ( P<0.05). The AUC values of combined detection of TTP, PI, PI/PIc and time intensity curve were all > 0.85, and the diagnostic value was high. Conclusions:The time-intensity curve of contrast-enhanced ultrasound is closely related to the main pathological features of cervical cancer, such as pathological type, lymph node metastasis and staging. According to the changes, the effect of radiotherapy and chemotherapy can be judged, which can provide a good reference for the diagnosis and treatment of cervical cancer.

Objective:To evaluate the efficacy and safety of combination therapy of eltrombopag, recombinant human thrombopoietin (rhTPO) , and standard immunosuppressive therapy (IST) for severe aplastic anemia (SAA) .Methods:A total of 16 cases with SAA treated with IST combined with eltrombopag and rhTPO were retrospectively analyzed.Results:At 3 months, the total response rate was 81.3%, and the complete hematological response rate was 37.5%. At 6 months, the total response rate was 87.5%, and the complete hematological response rate was 50.0%. The median time of platelet transfusion independence was 35 (16-78) days, the median time of red blood cell transfusion independence was 47.5 (15-105) days, the median platelet transfusion was 5.5 (3-20) U, and the median red blood cell transfusion was 6.5 (2-16) U.Conclusion:The combination of eltrombopag and rhTPO can improve the hematological response rate of IST for SAA and the quality of hematological remission with minimal toxic effects.

Objective:To analyze the military training injuries conditions and rehabilitation characteristics in Marine Corps, so as to provide reference for the military training injuries rehabilitation of special operations forces in the future.Methods:The medical records of 157 Marines with military training injuries admitted to a regional military rehabilitation center from June 2019 to December 2020 were retrospectively analyzed. The characteristics of military training injuries and therapeutic effects of rehabilitation were analyzed by referencing Diagnostic Criteria, Principles of Prophylaxis and Treatment of Military Training Injuries. Results:Among all the military training injuries, fracture has the highest incidence rate, followed by disc herniation, meniscus injury, ligament injury, and joint dislocation/sprain. There was no obvious correlation between the incidence of training injuries and the patient’s type of job; but there were some specific distribution patterns of diseases at different ages. The rehabilitation efficacy was positively correlated with the intervention time of rehabilitation. Psychological intervention could effectively improve the mental health of the officers and soldiers.Conclusion:In order to effectively promote the rehabilitation efficacy of military training injuries, reduce the non-combat attrition caused by military training injuries, and ensure the combat effectiveness of the Marine Corps, the following countermeasures are suggested: fully understanding the characteristics of training and the needs of rehabilitation of the Marines, popularizing the know-how to prevent military training injuries, standardizing the process of rehabilitation intervention, adopting individualized diagnosis and treatment, and implementing comprehensive psychological intervention.

Objective:To investigate the clinicopathologic features, treatment, and prognosis in patients with Castleman disease (CD) .Methods:We retrospectively analyzed the clinicopathologic data of 59 patients for whom a diagnosis of Castleman disease was confirmed using pathological examination from October 2011 to October 2019 at the Henan Cancer Hospital. The patients were divided into the following two groups as per the following clinical classifications: unicentric CD (UCD, n=47) and multicentric CD (MCD, n=12) . Data on clinical manifestations, laboratory findings, treatment, and prognosis were analyzed. Results:There was no significant difference in the median age and the ratio of male to female between the UCD and MCD. UCD was characterized by asymptomatic enlargement of the single lymph node. The main pathological type was hyaline vascular histopathology (83.0%) . Of these, 44 patients chose surgical resection, and their prognosis was good. Treatment. MCD was characterized by multiple enlarged superficial and/or deep lymph nodes with B symptoms, weakness, and hepatosplenomegaly. Anemia, hypoproteinemia, and globulin level were increased on laboratory examinations. Plasmacyte histopathology was the main pathological type and was present in about 50.0% of the subjects. Only chemotherapy was performed for these MCD patients, followed by chemotherapy or chemotherapy followed by radiotherapy, and the efficient was 58.3% (7/12) .Conclusions:UCD, characterized by asymptomatic enlargement of the single lymph node, shows good postoperative prognosis. MCD has relatively complex clinical manifestations and poor prognosis, and optimal treatment is yet to be established.

Objective: To explore the clinical features of patients with synchronous lymphoma and carcinoma. Methods: The clinical data of 17 patients with Synchronous lymphoma and carcinoma from February 2012 to October 2017 were analyzed retrospectively. Results: Among 17 patients of lymphoma, 1 case HL, 2 cases B-NHL, 6 cases MZBL, 3 cases DLBCL, 1 case mantle cell lymphoma (MCL) , 3 cases NK/T- cell lymphoma, 1 case anaplastic large cell lymphoma(ALCL). In terms of 17 patients with carcinoma, 3 cases esophageal carcinoma, 3 cases gastric carcinoma, 2 cases colorectal carcinoma, 7 cases thyroid carcinoma, 1 case hepatocellular carcinoma and lung cancer. Up to 15 patients received operation, and some of them combined with chemotherapy, radiotherapy and autologous transplant. Follow-up analysis showed that 3 cases was undergoing treatment, 2 cases lost follow-up, 4 cases died, 3 cases achieved CR, 3 cases remained to be at SD, and 2 cases assessed for progression or recurrence. Conclusion The relationship between lymphoma and carcinoma was under discussion, patients with synchronous lymphoma and carcinoma were not unusual. We herein should raise awareness to avoid misdiagnosis.
