Objective To observe the effect of moxibustion on the learning ability and memory of rat models of Alzheimer’s disease (AD) and the expression of amyloidβ protein (Aβ)-42, interleukin (IL)-1β, and IL-2, for unveiling the function and mechanism of moxibustion in treating AD.Method Forty-eight healthy male Sprague-Dawley rats were randomized into a sham-operation group, a model group, a Western medication group, and a moxibustion group, 12 rats in each group. The AD model rats were established by injection of Streptozotocin (STZ) into bilateral ventricles. From the 10th day after the operation, the moxibustion group started to receive moxibustion at Baihui (GV 20), Mingmen (GV 4), Changqiang (GV 1), and Guanyuan (CV 4); meanwhile, the Western medication group received Donepezil hydrochloride via intragastric administration. After 30-day treatment, the learning and memory ability was tested by using water maze, the hippocampal Aβ-42 was examined by immunohistochemical method, and the expression of hippocampal IL-1β and IL-2 was by double-antibody sandwich ELISA.Result Compared to the model group, moxibustion significantly down-regulated the levels of Aβ-42 (P<0.05) and IL-1β protein (P<0.05), up-regulated the level of IL-2 protein (P<0.05) in hippocampus, and markedly improved the learning and memory of AD rats (P<0.05).Conclusion Moxibustion can enhance the immunity and learning ability, which is plausibly related to the down-regulation of IL-1β, up-regulation of IL-2, and improvement of Aβ-42 in hippocampus.

Objective To investigate the effects of abdominal breathing training on sleep disorders in elderly patients with chronic heart failure. Methods Total of 100 patients with chronic heart failure complain of sleeping disorders and Pittsburgh Sleep Quality Index (PSQI)>7 points were assigned into two groups by random digits table method, 50 cases in each group. The observation group and the control group were nursed in the same way except that abdominal breathing was adapted to the observation group. Sleep status, heart rate, blood pressure, SpO2 and brain natriuretic peptide (BNP) were evaluated before training, one week and eight weeks after training respectively. Statistics was used to analyze the differences between two groups. Results After training one week, the sleep status of the observation group was ameliorated, but without significant difference compared to the control group (P>0.05). And after training eight weeks, the PSQI, BNP and heart rate were (9.21 ± 6.38) points, (193.78 ± 152.16) μg/L, (63.5 ± 10.8) times/min in the observation group, and (12.92 ± 0.33) points, (417.55 ± 262.47) μg/L, (70.7 ± 8.5) times/min in the control group, and there was significant differences between 2 groups (t=3.627, 2.041, 2.767, all P < 0.05), while the blood pressure, SpO2 did not change obviously(P>0.05). Conclusions Abdominal breathing training could ameliorate sleep status in elderly patients with chronic heart failure.

Objective To analyze driver genes status and its clinical characteristics of advanced lung adenocarcinoma, then evaluate the status of first-line treatment in a single centric real-world. Methods EGFR, ALK, ROS-1 gene in 204 advanced lung adenocarcinoma tissue were tested by ARMS-PCR method. And the relationship between driver genes status and clinical characteristics was analyzed as the first line treatment in real clinical practice. Results The positive rate of driver genes status in 204 advanced lung adenocarcinoma was 53.9％ (110/204) , including EGFR mutation 46.1％ (94/204) , ALK positive 6.4％ (13/204) and ROS1 positive 1.5％ (3/204). The driving genes status was significantly correlated with gender, smoking history, tumor staging and serosal invasion (P < 0.05). There were significantly differences among the proportion of first-line standard treatment in different subgroup (P = 0.000) , the first-line standard treatment rate of EGFR mutation, ALK/ROS1 positive and drive gene negative were 77.7％, 37.5％, and 46.8％ respectively. And the ratio of using 1 st generation EGFR-TKIs in all patients is 70.6％ (60/85). Conclusion More than half of advanced lung adenocarcinoma have driver genes changes, and EGFR-TKI first-line treatment has higher acceptability in real-word.

Objective:To investigate the immune effects of Clostridium difficile toxoid B (CdtB) vaccine formulated with different mucosal adjuvants through microneedle immunization, and to provide ideas for the prevention and treatment of Clostridium difficile infection. Methods:CdtB vaccine was prepared with purified Clostridium difficile toxin B(TcdB) after formaldehyde detoxification. Female BALB/c mice were immunized with different doses of vaccine alone or in combination with mucosal adjuvants. The titers of specific serum IgG and fecal IgA were detected at 0 d, 7 d, 14 d, 28 d and 42 d after immunization. The protective effects of CdtB vaccine were evaluated by cell neutralization assay and Clostridium difficile challenge infection. Results:(1) With the increase of immune dose, the mice immunized with CdtB vaccine alone by microneedle not only produced better serum specific IgG, but also had higher level of IgA in feces. (2) When the mice were immunized with CdtB vaccine containing LT or CTB adjuvant by microneedle, the trend of serum specific IgG titer in each group increased with the increase of immune dose, especially in the group containing LT adjuvant. There were significant differences in the trend of specific IgA titer in feces between the adjuvant groups and the group without adjuvant, but the adjuvant effect was not obvious. (3) No significant difference in serum IgG titer was observed between the mice immunized with 10 μg CdtB by microneedle or intraperitoneal injection, but microneedle immunization significantly increased fecal IgA level. (4) The neutralization titers of specific antibodies in mouse serum after immunization and the test results of challenge protection in mice confirmed that the use of CdtB vaccine had certain protective effects.Conclusions:CdtB vaccine had better immune effects in mice through microneedle immunization, but the adjuvant effects of LT and CTB were not significant.

Objective:To investigate the compliance of oral anticoagulant(OAC) medication and influencing factors among nonvalvular atrial fibrillation(NVAF) patients with new-onset acute ischemic stroke (AIS).Methods:A total of 396 NVAF patients, who initiated OAC therapy after a new-onset AIS from August 2011 to December 2020 were enrolled from China Atrial Fibrillation Registry (China-AF). The demographic characteristics, medical history, comorbid diseases and medication of patients were collected before and after the index stroke, and the influencing factors of compliance of OAC medication were analyzed.Results:Patients were followed up for a mean of 26.9 months. Among 396 patients, 228 (57.6%) had continuous anticoagulant medication (persistent OAC group);while 168 (42.4%) discontinued OAC therapy within 2 years after the index stroke (non-persistent OAC group). Patients on persistence OAC had a higher proportion of atrial fibrillation episodes than patients on non-persistent OAC [83.3% (190/228) vs. 73.8% (126/168); χ 2=5.34, P=0.021], while lower proportion of radiofrequency ablation(RFA)[18.9% (43/228) vs. 32.1% (43/228); χ 2=9.22, P=0.002]. Multivariate Cox regression modelshowed that history of RFA ( HR=1.77, 95% CI: 1.25-2.50; P=0.001) was positively associated with non-persistence of OAC. Conclusion:The study indicates that quite large proportion of NVAD patients with a new-onset of AIS discontinued OAC therapy during 2 years of follow up, and a history of RFA procedure might be an independent factor associated with discontinuing of anticoagulant therapy.

Objective To investigate the incidence of central obesity and characteristics and changing trend of macronutrient energy supply in adult residents of Chongqing, and to analyze the relationship between carbohydrate energy supply and central obesity. Methods Using the longitudinal tracking data of China Health and Nutrition Survey project, combined with China food composition table , the energy and nutrient intake and macronutrient energy supply ratio were calculated. The association between carbohydrate energy supply and central obesity was analyzed by multi-level statistical model. Results In 2011, 2015 and 2018, the carbohydrate supply ratio of adult residents in Chongqing was 43.02%, 46.52%, and 46.07%, respectively, and the difference was statistically significant (F=18.699, P<0.001). The overweight rates in 2011, 2015, and 2018 were 29.2%, 36.7%, and 37.8%, while the obesity rates were 12.2%, 13.5%, and 19.5%, respectively, with statistically significant differences (χ²=41.416, P<0.001). The central obesity rates were 51.5%, 57.2%, and 62.8%, respectively (χ²=21.008, P<0.001). The carbohydrate supply ratio was positively correlated with waist circumference. Compared to the population with a carbohydrate to energy ratio of <55%, the risk of central obesity in the population with a carbohydrate to energy ratio of ≥ 65% was 1.63 times higher. Conclusion The ratio of carbohydrate to energy supply of adult residents in Chongqing has slightly increased. Rates of overweight, obesity and central obesity are on the rise. A high carbohydrate to energy supply ratio may be a risk factor for central obesity.
