Objective To study the diagnosis and treatment of gastric stromal tumor(GST). Methods The clinical manifestation,pathological features ,diagnosis and treatment of 14 patients with GST were retrospectively analysed . Results Of the 14 GST,7 located in the fundus and the body of the stomach, 7 in the antrum of the stomach. The main symptom was abdominal pain, All the 14 GST were diagnosed by endoscopey, barium, ultrasound and CT. All patients were treated by excision. Histological diagnosis was as benign tumor in 8(57.1%)cases, uncertain types in 5 (35.7%)cases , and malignant tumor in 1 ( 7.1 %)case. There were local recurrence in 3 cases and death in 1 case after the operation. Conclusions The complete local excision is recommended for GST patients. Long term postoperative follow up is necessary for patients with GST. Reexcision may be helpful to the patients with recurrence or metastasis.

OBJECTIVE: To investigate the expression of inducible nitric oxide synthase (iNOS) and hypoxia-inducible factor 1(HIF-1) α in psoriatic lesions,and to explore their relationship with angiogenesis in psoriasis. METHODS: HIF-1α and iNOS protein were detected by immunohistochemistry and Western blot in 32 cases of psoriasis and 20 healthy controls,and CD34 marking vascular endothelial cells were used to measure the microvascular density (MVD). RESULTS: The expressions of HIF-1α and iNOS protein were very weak in the control skin, but very strong in psoriatic lesions, which showed significant difference in the expressions of iNOS and HIF-1α between the psoriasis and the control group(P<0.05). Expression of HIF-1α (r=0.743, P<0.01) and iNOS (r=0.639,P<0.01) had positive correlation with MVD in psoriasis respectively. There was a positive correlation between iNOS and HIF-1α expression in psoriasis (r=0.717, P<0.01). CONCLUSION Both iNOS and HIF-1α have high expression in psoriasis and might play an important role in the genesis and development of psoriasis.

Objective:The predictive value of LCR and BIS monitoring for delayed encephalopathy in acute severe carbon monoxide poisoning.Methods:Ninety-four patients with acute severe carbon monoxide poisoning treated in the Harrison International Peace Hospital Affiliated to Hebei Medical University between January 2017 and March 2019 were selected. According to whether DEACMP occurred within 60 days after discharge, the patients were divided into the DEACMP group ( n=33) and good prognosis group ( n=61). LCR and BIS of the two groups at different time points were compared, and the correlation between LCR and BIS was analyzed. The predictive value of LCR, BIS and the combination of the two for DEACMP was analyzed by receiver operating characteristic (ROC) curve. Results:The LCR and BIS of the DEACMP group at day 1t, 3 and 5 were significantly lower than those of the good prognosis group ( P<0.05). Pearson correlation analysis showed that there was a positive correlation between BIS and LCR in the DEACMP group at day 1, 3 and 5 ( r=0.371, P<0.05). There was also a positive correlation between LCR and BIS in the good prognosis group at day 1, 3 and 5 ( r=0.373, P<0.05). ROC curve analysis showed that the areas under the curves of LCR, BIS and the combination of the two for predicting the occurrence of DEACMP in patients with ASCOP were 0.803 (95% CI: 0.707~0.897), 0.941 (95% CI: 0.886~0.997), and 0.949 (95% CI: 0.879~1.000), respectively. Conclusions:LCR combined with BIS is of high predictive value for the occurrence of DEACMP in patients with ASCOP.
