[objective] To evaluate the effects of Aidi-injection to assist selective arterial infusion chemotherapy for advanced gastric cancer.[Methods]56 cases with advanced gastric cancer of TNM stage Ⅱ to Ⅲ were randomly divided into two groups.Treatment group(30 cases) received FAM regimen via selective arterial infusion chemotherapy,chemoembolization and Aidi-injection,control group(26 cases) received FAM regimen via selective arterial infusion chemotherapy and chemoembolization.Alleviation and metastasis,clinical symptoms,quality of life and side effects were compared between two groups.[Result] Aidi-injection reduced the side-effect of chemotherapy,improved physical status(PS) and regulated immunologic function.There was no difference about tumor effective rate between the two groups.[Conclusion]Aidei-injection in combination with seletive infusion chemothevapy has amrked cure effect and can improve life quality.

Objective To estimate the success rate of emergency endoscopic treatment in patients with esophagogastric variceal bleeding using self-made gastroscope outer casing and to investigate bow to prevent complications. Methods A total of 11 patients with esophagogastric variceal bleeding underwent endoscopic treatment with self-made gastroscope outer casing, which consisted of a wire reinforced plastic casing (1.05 cm in inner diameter, 1.35 cm in outer diameter and 50 cm in length), a 3.8 cm×3.8 cm balloon fixed on the casing head and its cavity connected to the gas pipeline placed in casing tail, an anti-reflux pad in the insert entrance of the endoscope tail as well.as a flushing hole. The endoscopy was introduced to the esophagus or stomch together with outer casing to wash and pump the hematocele out from the side of flushing hole. In patients with hemorrhagic lesion in esophageal vein, the balloon was used to press bleeding vein and intravascular sclerotherapy was performed simutanously. In those with hemorrhagic lesion in gastric vein, the balloon was pressed on esophageal vein near to the cardia and intravascular sclerotherapy was performed. Results During the process of examination, the hemorrhagic lesion was fully exposed because of flushing, and bleeding was controlted in all patients after sclerotherapy. No complication such as aspiration or perforation was seen. Conclusions For emergency endoscopic treatment of esophagogastric variceal bleeding, gastroscope outer casing is helpful in removing intragastric hematocele and maintaining a clear field of vision. It can be effectively improving the efficacy of sclerot herapy.

Objective:To construct an automatic recognition system for PD patients with freezing of gait (FOG) based on mobile phone videos by recording the gait videos of PD patients with FOG.Methods:Forty-nine PD patients with FOG, admitted to our hospital from December 2020 to May 2021, were chosen in our study. Their clinical data were collected. The processes of these patients accepted "3-meter-round trip" and "3-meter-round trip through narrow (0.6 m)" were recorded and 87 valid gait videos were extracted. Position signals of key points in the video were extracted, and featured data were extracted after signal preprocessing. From the featured data, action recognition model, straight FOG recognition model and turn FOG recognition model were established respectively, and finally end-to-end FOG recognition model was formed. Leave-one-subject-out (LOSO) method was used to evaluate the performance of the above models.Results:A total of 22 066 non-FOG window samples and 3815 FOG window samples were obtained from 87 valid videos, which constituted the training sample pool of this study. LOSO method showed that the motion recognition model enjoyed 83.27% sensitivity, 91.38% specificity, and 89.28% accuracy; the straight FOG recognition model enjoyed 57.69% sensitivity and 88.12% specificity; the turn FOG recognition model enjoyed 61.54% sensitivity and specificity 98.72%; and the end-to-end FOG recognition model enjoyed 85.71% sensitivity and 75.73% specificity.Conclusion:The automatic recognition system for PD patients with FOG based on mobile phone videos has relatively high sensitivity and specificity, which can realize remote assessment and is convenient for screening and follow-up of PD patients with FOG.
