Objective To evaluate the short-term effects of comprehensive health management interventions for stroke high-risk population screening on the prevention and treatment of ischemic stroke, and to provide reference and basis for improving and exploring health management and prevention strategies for stroke high-risk population. Methods From 2018 to 2022, 13 community health service centers in Jiading District, Shanghai were selected in the present study. Based on information push platform, stroke risk assessment and health intervention follow-up were conducted for community residents through convenience sampling. The residents were divided into a full course intervention group (intervention group) and a routine intervention group (control group) according to different health intervention measures and forms. The incidence of ischemic stroke in the two groups of survey subjects was tracked within 36 months. Results A total of 52144 subjects were included in the study. The total number of patients in the full course intervention group was 14227, with an incidence density of 577.32/100 000 (556.49/100 000-598.12/100 000), which was lower than that of the conventional intervention group (37 917), with an incidence density of 1 485.47/100 000 (1 464.99/100 000-1 505.94/100 000) (χ²=2490.212, P<0.001). The relative risk of the full course intervention group was 0.39, and the relative risk of stroke risk factors in the full course intervention group from low to high was 0.33, 0.43, 0.45, and 0.49, respectively. The incidence density of males in the full course intervention group was 660.76 (627.46/100 000 - 694.05/100 000), with a relative risk of 0.43, and the incidence density of female patients was 509.71/100 000 (483.37/100 000 - 536.05/100 000), with a relative risk of 0.35. The overall incidence density of the population under 62 years old gourp, 62-75 years old group and over 75 years old group was 197.45/100 000 (173.09/100 000 -221.80/100 000), 608.36/100 000 (580.19/100 000-636.54/100 000), and 1 025.06/100 000 (958.51/100 000-1 091.61/100 000), with relative risks of 0.51, 0.44, and 0.38, respectively. Conclusion Comprehensive health management measures can effectively reduce the short-term risk of ischemic stroke, and should be further promoted and improved to enhance the effectiveness of stroke prevention and control.

In view of the high incidence of malignant diseases such as malignant arrhythmias in the elderly population, accidental injuries such as falls, and the problem of no witnesses when danger occurs, the study developed a human vital signs and body posture monitoring and positioning alarm system. Through the collection and analysis of electrocardiogram (ECG), respiration (RESP) and acceleration (ACC) signals, the system monitors human vital signs and body posture in real time, automatically judges critical states such as malignant arrhythmias and accidental falls on the local device side, and then issues alarm information, opens the positioning function, and uploads physiological information and patient location information through 4G communication. Experiments have shown that the system can accurately determine the occurrence of ventricular fibrillation and falls, and issue position and alarm information.

Objective To study the clinical and pathological characteristics of early gastric cancer ( EGC) and to evaluate the value of blue laser imaging combined with magnification endoscopy ( BLI-ME) in the diagnosis of EGC. Methods A retrospective study was conducted on data of 255 patients with EGC diagnosed in Huashan Hospital from January 2014 to January 2017, including 33 cases of preoperative BLI-ME intensive examination. According to the Japanese classification of gastric carcinoma of Japanese Gastric Cancer Association, the EGCs were histopathologically divided into differentiated and undifferentiated subtypes. Clinical characteristics, endoscopic features, pathological type, lymph node metastasis, and lesion characteristics of BLI-ME were analyzed. Results Among the 255 cases of EGC, 164 cases ( 63. 31％) were male, 242 cases ( 94. 90％) were over 40 years old, 182 cases ( 71. 37％) belonged to differentiated type, 93 cases ( 36. 47％) were located in gastric antrum, 92 cases ( 36. 08％) were type 0-Ⅱc under endoscopy, and 37 cases (14. 51％) had lymph node metastasis. Comparative analysis showed that the lymph node metastasis rate was significantly lower in mucosal carcinoma compared to submucosal carcinoma[ 5. 04％(7/139) VS 25. 86％ (30/116),χ2=22. 109, P=0. 000], lower in differentiated carcinoma compared to undifferentiated carcinoma[9. 89％ (18/182) VS 26. 03％ (19/73), χ2=10. 938, P=0. 002], and lower in tumors with maximum diameter of lesion≤2. 0 cm compared to maximum diameter of lesion>2. 0 cm [ 9. 88％ ( 16/162 ) VS 22. 58％ ( 21/93 ) , χ2 =7. 687, P=0. 009 ] . Among the 33 cases undergoing BLI-ME, differentiated EGC was mainly fine-network pattern (13. 64％, 3/22), intralobular loop pattern (ILL)-1 (59. 09％, 13/22) and ILL-2 (22. 73％, 5/22), whereas undifferentiated subtype patients were characterized as ILL-2 ( 45. 45％, 5/11 ) and corkscrew pattern ( 54. 55％, 6/11 ) . Conclusion The incidence of EGC is higher in male with age over 40 years. Gastric lesions occur most frequently in the antrum, and the most common microscopic morphology is 0-Ⅱc type. Tumor>2. 0 cm or invasion of submucous layer, and undifferentiated carcinoma are prone to lymph node metastasis. The assessment of mucosal microvascular pattern and micro surface structure under BLI-ME facilitate to determine the pathological type of EGC.

OBJECTIVE: To determine the expression of MTA1 and RECK gene in nasopharyngeal carcinoma (NPC) and its correlation with clinicopathological features. METHOD: In situ hybridization was used to detect the expression of MTA1 and RECK mRNA in 60 cases of primary NPC (30 cases with, 30 cases without cervical lymph node metastasis), 10 cases of metastatic lymph node (MLN) and 20 cases of chronic nasopharyngitis tissue (CNT). RESULT: 1) Positive rates of MTA1 mRNA expression in CNT, NPC and MLN were 30.0% (6/20), 71.7% (43/60) and 80.0% (8/10), respectively. The positive expressions of MTA1 in NPC and MLN were significantly higher than in CNT (P<0.05). The MTA1 mRNA expression in NPC with lymph node metastasis was significantly higher than in NPC without lymph node metastasis (83.3% vs. 60.0%, P<0.05). 2) Positive rates of RECK mRNA expression in CNT, NPC and MLN were 85.0% (17/20), 26.7% (16/60) and 30.0% (3/10), respectively. The positive expression of RECK in NPC and MLN were significantly lower than in CNT (P< 0.05). The RECK mRNA expression in NPC with lymph node metastasis was significantly lower than in NPC without lymph node metastasis (13.3% vs. 40.0%, P<0.05). 3) Abnormal expression of MTA1 and RECK mRNA in NPC had no correlation with gender, age, T-stage and clinical stage (P>0.05), while they had positive relationship with lymph node metastasis, tumor recurrence and the post-treatment 5-year survival periods of NPC (P<0.05). The expression of RECK mRNA was negatively correlated with the expression of MTA1 mRNA in NPC (r = - 0.541, P<0.05). CONCLUSION These data suggest that the aberrant expression of MTA1 and RECK gene may be involved in the invasion and metastasis of NPC. They may be good biomarkers for evaluating the cervical lymph node metastasis, recurrence and prognosis of NPC.

Objective To compare the different expressions of transforming growth factor beta1 (TGFβ1) and its type one receptor(TGFβR1) between primary pancreatic cancer cell line AsPC-1 and metastatic pancreatic cancer cell line BxPC-3. Methods The mRNA expressions of TGFβ1 and TGFβR1 in AsPC-1 and BxPC-3 pancreatic carcer cell lines were quantatitived by real-time RT-PCR. The protein levels of TGFβ1 and TGFβR1 in these two cell lines were measured by Western blot assay. Results Compared with the primary pancreatic cancer cell AsPC-1, the mRNA and protein expressions of TGFβ1 and TGFβR1 were much higher in BxPC-3 pancreatic cancer cells(P<0.05). Conclusions Upregulations of TGFβ1 and TGFβR1 might be a pivotal incidence in the procedure of malignant progressing and metastasis in pancreatic cancer cells.
