OBJECTIVETo explore the changes and their clinical significance of D-dimer and platelet glycoprotein (GP) in patients with coronary heart disease.

METHODSD-dimer and GP in 20 patients with stable angina (SA group), 48 patients with unstable angina (UA group), and 20 control cases were measured. The changes of D-dimer and GP in patients with and without coronary events were compared. The sensitivity of those changes in the diagnosis of coronary events was evaluated.

RESULTSThere were significant differences of D-dimer and GP between UA group and SA group or control group (P < 0.01), while there was no significant difference between SA group and control group (P > 0.05). There were also significant differences of D-dimer and GP between patients with coronary events and patients without coronary events (P < 0.05). In the sensitivity test for detecting coronary events, D-dimer and GPIIb, GPIIIa were much more sensitive than other parameters.

CONCLUSIONSD-dimer and GPIIb, GPIIIa may be regarded as the indexes of coronary thrombosis and used for predicting the severity of coronary events.

Objective:To investigate the short-term clinical efficacy of laparo-gastroscopic esophagectomy (LGE).Methods:The retrospective and descriptive study was conducted. The clini-copathological data of 11 patients with esophageal cancer who underwent LGE in the Zhongshan Hospital of Fudan University from June 2020 to October 2021 were collected. There were 8 males and 3 females, aged (68±4)years. Sorted by operation time, the sentinel lymph nodes navigation (SLN) was performed since the sixth patient in the cohort, and abdominal surgery and neck surgery were performed simultaneously to complete LGE. Observation indicators: (1) surgical situations; (2) postoperative situations; (3) follow-up. Follow-up was conducted using outpatient examination or telephone interview to detect death of patients during postoperative 30 days. Patients were followed up during postoperative 30 days. Measurement data with normal distribution were represented as Mean± SD, and count data were described as absolute numbers. Results:(1) Surgical situations. Of the 11 patients, 5 cases received SLN with satisfactory visualization, 6 cases did not receive SLN, 1 case terminated the operation as sentinel lymph nodes biopsy showing positive results and the rest of 10 cases completed LGE successfully without conversion to thoracotomy. The operation time and tumor diameter of the 10 patients completing LGE was (204±27)minutes and (2.5±1.0)cm, respec-tively. (2) Postoperative situations. Of the 10 patients completing LGE, 2 cases had pulmonary complications after surgery and recovered well with symptomatic treatment, and none of patient had anastomotic leakage or other serious complication. Results of postoperative histopathological examination showed squamous cell carcinoma in the 10 patients completing LGE. Nine patients were classified as T1b?3N0M0 stage and 1 patient was classified as T1bN1M0 stage. Ten patients completing LGE had R 0 resection and the number of lymph nodes dissected was 14±4. There were 3 cases with nerve bundle invasion, 2 cases with vascular invasion and 5 cases without nerve bundle and vascular invasion. The postoperative treatment time at intensive care unit and duration of hospital stay of the 10 patients completing LGE were (4.0±2.4)days and (7.2±1.5)days. (3) Follow-up. The 10 patients completing LGE were followed up and none of them died during the postoperative 30 days. Conclusions:LGE is safe and feasible. Combined with SLN can guarantee the oncology effect of surgery.

This study was aimed to explore the clinical characteristics and therapeutic efficacy of normal karyotype AML patients with CEBPA mutations. Fifty-five de novo AML patients with normal karyotype were retrospectively analyzed with regard to frequency of CEBPA mutation, clinical characteristics and therapeutic response. The results showed that CEBPA mutation was detected in 20 patients (36.4%), among them 17 cases displayed double mutations, three cases were with single mutation. The clinical characteristics of patients with CEBPA mutation displayed as follows: 75% of AML patients with CEBPA mutation were AML-M1 and AML-M2, the hemoglobin level at newly diagnosis was higher and the platelet count at newly diagnosis time was lower than those of AML patients without CEBPA mutation [(98.30 ± 20.33) g/L vs (81.69 ± 23.74) g/L (P < 0.05); and (33.30 ± 38.27) ×10(9)/L vs (64.79 ± 61.60) ×10(9)/L (P < 0.05)]. The leukemic cells highly expressed CD7 and CD34. The therapeutic efficacy of 1 cycle for AML patients with CEBPA mutation was satisfactory (72.2%), was higher than that of patients without CEBPA mutation(68.6%), but there was no statistical significance (P > 0.05). It is concluded that AML with CEBPA mutation is more observed in AML-M1 and AML-M2, and accompanies by high level of hemoglobin and lower platelet count, expression of CD7 and CD34. Early-term therapeutic efficacy is satisfactory. The frequency of CEBPA mutation may be higher in Chinese patients with AML compared with that reported in Western world.
