ObjectiveTo explore the differences and similarities of the featurs of lymph node metatasis of abdominal esophageal carcinoma and cardiac cancer. MethodsPreoperative CT images of abdominal esophageal carcinomas and cardiac cancers were reviewed and analysed on lymph node size and preponderant distribution. ResultsShort diameter ≥10 mm of lymph node at CT was adopted as metastasis criterion. The detection rates of abdominal esophageal carcinomas and cardiac cancers were 73.5%（144/196） and 83.7% （170/203）, respectively. Thoracic lymph node metastasis rate of abdominal esophageal carcinomas was 11.1% （4/36） in 7 area, 27.8% （10/36） in 8 area, 8.3% （3/36） in 9 area, while celiac lymph node metastasis rate was 36.1% (13/36 ） in No.7 group, 19.4% （7/36） in No.1 group, and 11.1% （4/36） in No.2 group primarily. Lymph node metastasis rate of cardiac cancers was 17.9% （5/28） in No.1 group, 28.6% （8/28） in No.2 group, 39.3% （11/28 ） in No.3 group, and 25.0% （7/28） in No.4 group for the first stop lymph nodes, and 35.7% （10/28 ） in No.7 group for the second stop primarily. ConclusionAs metastasis criterion, short diameter ≥10 mm of lymph node at CT is feasible, but there exist certain falsepositive rate. Thoracic lymph node metastasis of abdominal esophageal carcinomas is mainly in the 7, 8, and 9 area, while celiac metastasis is mainly in No.7, No.1, and No.2 groups. Lymph node metastasis of cardiac cancers is in No.1, No.2, No.3, No.4, and No.7 group primarily.
Objective To explore the impact of Diagnosis-Intervention Packet (DIP) reform on the operation of pilot county-level hospital, analyze the challenges that hospitals may face in DIP reform, and propose strategies to adapt to the reform. Methods The settlement list data of inpatients insured by medical insurance for 2022 from a county-level tertiary public hospital in Jiuquan City, Gansu Province were collected, where DIP was planned to operate. The DIP payment was simulated, and the operational status of the hospital and departments after implementing DIP reform was analyzed based on enrollment status, cost deviation, length of stay, hospitalization expenses, and DIP payment as relevant indicators. Results Under the implementation of DIP payment, the overall enrollment rate of the hospital was 98.1%, including 85.4% in the core group, 7.0% in the comprehensive group, and 7.6% in the grassroots group. Normal costs accounted for 88.9%, deviation costs accounted for 11.1%, with high magnification cases accounting for 1.9% and low magnification cases accounting for 9.2%. The payment standard for all cases included in the hospital according to DIP was 15.464 million yuan, the total amount paid by the pooling fund was 19.986 million yuan, and the difference between DIP payment and payment by project was –4.522 million yuan. Conclusion There is a significant difference in the medical insurance payments received by county-level hospitals after implementing DIP payment, and there is an urgent need to adapt to the DIP payment reform as soon as possible.
Objective To explore the manifestations and features of multi-slice spiral CT （MSCT） in the diagnosisof papillary thyroid carcinoma （PTC）. Methods Preoperative MSCT data of 35 cases of PTC proved by operation and pathology in our hospital form May. to Jun. in 2013 were observed retrospectively， to analyze the manifestations and characteristics of MSCT for it. Results Of 35 patients with PTC， MSCT totally showed 48 lesions， 68.6% （24/35） of patients with single lesion， 31.4% （11/35） of patients with 2-3 lesions， and 62.9% （22/35） of patients with lymph node metastasis. Of the 48 lesions， 29.2% （14/48） of lesions located in the left lobe， 70.8% （34/48） of lesions located in the right lobe；the lesions’ maximum diameter were 0.4-5.8cm， with the average maximum diameter of 1.3cm. There were 39.6% （19/48） of lesions with uneven density， 25.0% （12/48） of lesions with irregular shape， 47.9% （23/48） of lesions with blurred edges， 18.8% （9/48） of lesions had papillary enhanced tumor nodules， 10.4% （5/48） of lesions had peritumoral incomplete enhanced ring sign， 22.9% （11/48） of lesions invaded surrounding tissue or organs. There were 35.4% （17/48） of lesions had calcification， in which 76.4% （13/17） of lesions were fine granular calcification， 11.8% （2/17） of lesions were mixed calcification， and 11.8% （2/17） of lesions were coarse calcification. Conclusion MSCT manifestations of PTC have certain characteristics， which can provide imaging basis for clinical treatment options.
