Objective:To investigate the value of serum gastrin-17 (G-17), pepsinogen (PG) I and II, and narrow-band imaging endoscopy in combination for identifying early gastric cancer.Methods:A total of 86 patients with suspected gastric cancer admitted to Zhoushan Hospital from January to September 2021 were included in this study. These patients underwent serum G-17, PG I, and PG II examination and narrow-band imaging endoscopy. PG I/PG II ratio (PGR) was calculated. Taking pathological results as a gold standard, the sensitivity, specificity, and accuracy of serum G-17, PG I, PG II, and narrow-band imaging endoscopy in combination for identifying early gastric cancer were calculated.Results:Serum G-17 level and PGR in the gastric cancer group were (20.14 ± 4.59) pmol/L and (20.21 ± 4.50) μg/L, respectively, which were significantly higher than (17.06 ± 4.05) pmol/L and (17.15 ± 4.08) μg/L in the atrophic gastritis group ( q = 4.12, 3.77, both P < 0.05) and (12.35 ± 3.31) pmol/L and (10.82 ± 5.26) μg/L in the non-atrophic gastritis group ( q = 9.34, 10.39, both P < 0.05). PG I and PGR in the gastric cancer group were (63.90 ± 14.41) μg/L and (3.17 ± 2.08), respectively, which were significantly lower than (79.34 ± 16.25) μg/L and (5.04 ± 3.61) in the atrophic gastritis group ( q = 5.33, 3.44, both P < 0.05) and (106.42 ± 20.18) μg/L and (9.22 ± 4.06) in the non-atrophic gastritis group ( q = 13.16, 9.97, both P < 0.05). Among the 86 patients included, gastric cancer was determined by biopsy in 43 patients. Pathological results showed that 37 patients had early gastric cancer and 6 patients had gastric cancer involving the muscle layer or serous layer. Narrow-band imaging endoscopy results showed that 83.78% (31/37) of patients had early gastric cancer. Serum G-17, PG, and narrow-band imaging endoscopy in combination showed that 91.89% (34/37) of patients had early gastric cancer. Taking pathological results as a gold standard, the sensitivity, specificity, positive predictive value, and negative predictive value of serum G-17 combined with PG for screening early gastric cancer were 72.97% (27/37), 77.55% (38/49), 71.05% (27/38), and 79.17% (38/48), respectively. The sensitivity, specificity, positive predictive value, and negative predictive value of narrow-band imaging endoscopy for screening early gastric cancer were 83.78% (31/37), 85.71% (42/49), 83.10% (31/38), and 87.50% (42/48). The sensitivity and specificity of serum G-17, PG, and narrow-band imaging endoscopy in combination for screening early gastric cancer were 91.89% (34/37) and 91.84% (45/49), respectively. Conclusion:Serum G-17, pepsinogen, and narrow-band imaging endoscopy in combination can improve the diagnostic accuracy of early gastric cancer and is an effective method for screening early gastric cancer.

Objective To study the value of reverse CT scan in eliminating the respiratory motion artifacts in the thoracic CT of the patients with chronic obstructive pulmonary diseases(COPD).Methods Fourty patients with COPD were randomly selected and underwent chest CT examinations with the technique of GR-Helical including directive and reverse CT scans.The images were blindly evaluated by three experienced doctors.Results In 40 cases,the respiratory motion artifacts were present in 17 cases,among them,70.59%(12/17) artifacts was in lower lung field,and 64.7%(11/17) artifacts occurred in the people over 60 years of age.The rate of artifact was 35% at directive scan,while it was reduced to 7.5% at reverse scan,the image quality was improved at 27.5%.There was statistical significance in eliminating respiratory motion artifacts between two scanning method (P＜0.05).Conclusion Reverse CT scanning can effectively eliminating or reducing the respiratory motion artifacts in lower lung field,it is the best choice of scanning mode in elderly patients with COPD.

Conclusions The comprehensive control measures along the Xinglong River are effective and the management and surveillance of snail environments still should be strengthened.

Objective To compare the clinical efficacy of two different injection ways in treating lower extremity varicose veins with foam sclerotherapy of lauromacrogol. Methods During the period from Dec. 2010 to Dec. 2012 a total of 80 patients with clinically-proved lower extremity varicosis were admitted to authors’ hospital. The patients were randomly and equally divided into two groups:anterograde group (n=40) and retrograde group (n=40). For patients of anterograde group, under fluoroscopy guidance the needle was directly punctured into the distal end of the varicose vein with subsequent injection of 1%lauromacrogol foam sclerosing agent, while for patients of retrograde group the opposite femoral vein was punctured by using Seldinger technique, then a catheter was inserted into the proximal part of the great saphenous vein of the diseased side, and 1%lauromacrogol foam sclerosing agent was injected into the varicose vein. The operation time, recovery time, the dosage of the sclerosing agent used, the incidence of complications and the use of additional treatment were recorded, and the results were statistically analyzed. All the patients were followed up for 3 - 6 months. Results No significant difference in the overall effective rate existed between the two groups at 3-6 months after the treatment (P>0.05). The preoperative and postoperative CEAP scores of the anterograde group were 3.70 ± 0.63 and 0.88 ± 1.18 respectively, while the preoperative and postoperative CEAP scores of the retrograde group were 3.73 ± 0.59 and 0.88 ± 1.27 respectively. The difference in CEAP score between preoperative values and postoperative ones was statistically significant in both anterograde group and retrograde group (P < 0.05). Besides, the differences in the operation time, recovery time, the dosage of the sclerosing agent used, the incidence of complications and the use of additional treatment between the two groups were also statistically significant. Conclusion In treating lower extremity varicose veins with foam sclerotherapy of lauromacrogol, the overall effectiveness of anterograde injection and retrograde injection is quite the same. As each injection way has its own advantages and disadvantages, the therapeutic scheme should be individualized for each patient.
