Objective:To investigate the global cognitive function and the function of specific cognitive domains in hypertensive patients at high risk of cardiovascular disease in China, and to explore the impact of cognition function on blood pressure control.Methods:This is a cross-sectional survey. Data were obtained from the ESPRIT study. Patients with a history of hypertension who participated in the ESPRIT study from September 2019 to July 2020 were selected. Mini-mental state examination (MMSE) was used to evaluate patients′ overall cognition and the function of each cognitive domain. According to the total MMSE score, patients were divided into the cognitive-intact group (MMSE total score=30 points), cognitive-declined group (MMSE total score<30 points, but did not reach the dementia screening threshold) and cognitive-impaired group (MMSE total score reached the dementia screening threshold). A multivariable logistic regression model was used to explore the effects of cognitive function and MMSE score on blood pressure control. The years of education were removed from the adjustment variables for sensitivity analysis. The interaction effect modeling of stratified variables and exposed variables was used for hierarchical analysis.Results:A total of 10 834 patients with hypertension at high risk of cardiovascular disease were enrolled, aged 65 (60, 69) years and 4 476 (41.3%) patients were female. There were 989 patients in cognitive-intact group, 8 676 patients in cognitive-declined group and 1 169 patients in cognitive-impaired group. The MMSE score of all included patients was (25.6±3.8) points. In the overall study population, 10.8% (1 169/10 834) of hypertensive patients had cognitive impairment, with an MMSE total score of (18.6±4.1) points. The cognitive domains with obvious impairment were recall memory (-80%), visuospatial function (-64%), attention and computation (-60%); 80.1% (8 676/10 834) of hypertensive patients did not meet the criteria for cognitive dysfunction, but had cognitive decline, and the cognitive domains with significant impairment were recall memory (-51%) and visuospatial structure (-23%). Multivariate logistic regression analysis showed that cognitive dysfunction ( OR=0.88, 95% CI: 0.72-1.08, P=0.212) and cognitive decline ( OR=0.96, 95% CI: 0.83-1.12, P=0.629) was not correlated with blood pressure control. MMSE total score and scores in each cognitive domain were not correlated with blood pressure control ( P>0.05). Sensitivity analysis showed that cognitive function was not related to blood pressure control (all P>0.05). Stratified analysis according to different frequency of medication showed that cognitive function and MMSE score were not correlated with blood pressure control ( P>0.05). Conclusion:One in ten hypertensive patients who were at high risk of cardiovascular disease have comorbid cognitive impairment. In patients with high risk of cardiovascular disease, the most affected cognitive domains were recall memory, visuospatial function, attention and calculation. Part of hypertensive patients have not reached the level of cognitive dysfunction, but have begun to show cognitive decline. Cognitive function is not an independent influencing factor on blood pressure control.

Objective:To explore the efficacy of precise and empirical bismuth-containing quadruple therapy guided by clarithromycin sensitivity testing in the first eradication of Helicobacter pylori ( H. pylori) in Ningxia. Methods:From August 12, 2022 to March 22, 2023, 600 patients diagnosed as H. pylori-positive by 14C-urea breath test ( 14C-UBT) for the first time in People′s Hospital of Ningxia Hui Autonomous Region, Ningnan Hospital of People′s Hospital of Ningxia Hui Autonomous Region, Zhongwei People′s Hospital, Yanchi County People′s Hospital, and Pingluo People′s Hospital were selected, and divided into empirical treatment group (hereinafter referred to as the empirical group), genetic testing group (hereinafter referred to as the genetic group), and drug sensitivity testing group (hereinafter referred to as the drug sensitivity group) by using random number table with 200 patients in each group. The empirical group did not undergo drug sensitivity testing and genetic testing, while the genetic and drug sensitivity groups were confirmed to be sensitive to clarithromycin through genetic testing and drug sensitivity testing, and the patients with drug-resistant were excluded, respectively. All the patients of the 3 groups received the same clarithromycin bismuth-containing quadruple therapy. Intention-to-treat (ITT) and per-protocol (PP) analyses were performed to compare the eradication rates of H. pylori among 3 groups. Cost-effectiveness ratio (CER) and incremental cost-effectiveness ratio (ICER) were used for cost-effectiveness and sensitivity analysis based on the ITT. Chi-square test was used for statistical analysis. Results:There were 200, 126, and 168 patients included in the empirical group, genetic group, and drug sensitivity group in ITT analysis, and 190, 123, and 164 patients were enrolled in the 3 groups in PP analysis, respectively. The results of ITT analysis showed that the eradication rates of H. pylori in the empirical group, genetic group, and drug sensitivity group were 80.5% (161/200), 94.4% (119/126), and 95.2% (160/168), respectively. The results of PP analysis indicated that the eradication rates of H. pylori in the 3 groups were 84.7% (161/190), 96.7% (119/123), and 97.6% (160/164), respectively, and the differences were statistically significant ( χ2=25.39 and 24.93, both P<0.001). The H. pylori eradication rates of genetic group and drug sensitivity group were both higher than that of empirical group in ITT and PP analysis( χ2=12.40, 17.80, 11.42, and 17.13; all P<0.001). The cost-effectiveness analysis showed that the direct treatment cost of the empirical group, genetic group, and drug sensitivity group was 400.8, 729.2, and 779.2 yuan, respectively, and the CER was 4.98, 7.72, and 8.18 yuan/%, respectively. Compared to the empirical group, the ICER of the genetic group and drug sensitivity group was 23.6 and 25.7 yuan/%, respectively. The sensitivity analysis demonstrated that, when the cost of genetic testing reduced or increased by 20%, the ICER of the genetic group compared to the empirical group was 21.8 or 25.5 yuan/%, respectively. When the cost of drug sensitivity testing reduced or increased by 20%, the ICER of the drug sensitivity group compared to the empirical group was 23.3 or 28.2 yuan/%. When the cost of gastroscopy reduced or increased by 20%, the ICER of the genetic group compared to the empirical group was 20.8 or 26.5 yuan/%, and the ICER of the drug sensitivity group compared to the empirical group was 23.0 or 28.4 yuan/%, respectively. Conclusion:In Ningxia, if the clarithromycin bismuth-containing quadruple regimen is applied as the first H. pylori eradication regimen, in order to achieve the clinical eradication efficacy of H. pylori, and the patients can accept an additional payment of 23.6 or 25.7 yuan for each 1% increasing in the H. pylori eradication rate, then the precision treatment after clarithromycin resistance test is recommended.

OBJECTIVE To explore the distribution of airborne pollen in Cangzhou,to analyze the correlation between pollen characteristics,meteorological factors and the rate of allergic rhinitis visits,and to provide a reference basis for the precise prevention and treatment of allergic rhinitis in Cangzhou.METHODS The gravity deposition method was applied to collect daily airborne pollen from the monitoring sites in Cangzhou from March to October 2022 and record the pollen species and quantities.We also collected information on allergic rhinitis patients who visited the ENT Department of Cangzhou Central Hospital during the same period and meteorological data(daily maximum temperature,minimum temperature,maximum relative humidity,maximum precipitation,and maximum wind speed at ground level)during the same period,and analyzed the relationship between the number of AR patients'visits,the amount of pollen,and the meteorological factors.RESULTS 1.A total of 229 pollen exposures were collected from March to October 2022,totaling 19 368 pollen grains,of which 18 750 grains of pollen could be identified in 19 families and 618 grains were difficult to identify the families.2.There were two peaks of pollen during the period,in April and September respectively.Spring pollen to tree-based category,to the pine family,willow willow family,Xylariaceae(ash)most often;summer pollen volume has declined,but still tree-based category;fall pollen to herbaceous category,to the Asteraceae Artemisia,mulberry,Gramineae most often.3.The pollen concentration in Cangzhou City was negatively correlated with maximum humidity,maximum precipitation,maximum temperature,and minimum temperature.Maximum wind speed at ground level was positively correlated with pollen concentration.4.Pollen concentration was positively correlated with the number of visits.The correlation analysis between daily medical visits from June to October and air pollen concentration showed a significant positive correlation,while the results from March to May showed no significant correlation.CONCLUSION The peak of airborne pollen dispersal in April and September in Cangzhou.Spring and summer pollen is dominated by tree species,and the dominant pollen is Pinaceae,Willow genus of Populus,and Xylariaceae(ash genus);fall pollen is dominated by herbaceous species,and the dominant pollen is Artemisia,Asteraceae,Mulberry,and Gramineae.Meteorological factors are important factors affecting pollen concentration.Within a certain range,the lower the maximum humidity,the lowest maximum precipitation,the lower the highest or the lowest temperature,the higher the pollen concentration,and the pollen concentration is more affected by the lowest temperature.There is a correlation between pollen concentration and the number of AR patients'visits from June to October,which can be used as an environmental early warning indicator of the prevalence of AR.

Conclusions:Dapagliflozin has a good effect in the treatment of patients with early diabetic nephropathy. It can lower glucose, improve Cys-C, reduce urinary microalbumin and protect renal function.

Objective:To investigate the clinical efficacy of anal dimple anorectoplasty on female infants with congenital anal atresia combined rectal vestibular fistula.Methods:Clinical data of 69 female infants with congenital anal atresia combined rectal vestibular fistula admitted to Department of Pediatric Surgery, the First Affiliated Hospital of Zhengzhou University from July 2012 to July 2022 were retrospectively analyzed.They were divided into 2 groups according to the surgical methods: 34 cases of anal dimple anorectoplasty(group A) and 35 cases of anterior sagittal anorectoplasty(group B). The operation time, length of stay, short-term complications, long-term complications and bowel function (determined by the Rintala score at 6 months postoperatively) of the two groups were compared.The difference in the incidence of postoperative complications between groups was compared by Chi- square test, and the remaining differences between groups were compared by the paired t-test. Results:The operative time [(80.18±9.29) min vs.(103.85±8.26) min] and postoperative hospital stay[(6.10±1.52) d vs.(7.63±2.40) d] in group A were significantly shorter than those of group B ( t=11.40, 2.62; all P<0.05). The Rintala total score at 6 months postoperatively in group A was significantly higher than that of group B[(19.36±0.93) points vs.(18.76±0.44) points]( t=3.20, P<0.05). There were no significant differences in the incidences of short-term [(4/34, 11.8%) vs.(7/35, 20.0%)] and long-term complications [(2/34, 5.9%) vs.(4/35, 11.4%)]between group A and group B ( χ2=0.75, 0.75; all P>0.05). Conclusions:Anal dimple anorectoplasty for female infants with congenital anal atresia combined rectal vestibular fistula is safe and effective.

Objective:To investigate the application value of jigsaw puzzle flap based on free-style perforator in repairing the defect on groin and adjacent organ after tumor extended resection.Methods:From December 2013 to August 2019, the data was focused on the patients who underwent soft tissue defect repair of groin and adjacent areas in the Second Affiliated Hospital of Chengdu Medical College. After the defect was predetermined preoperatively, portable ultrasound Doppler was used to map multiple perforators adjacent to the defect. The large defect was divided into several small parts, based on the location of perforators, the intensity of the Doppler, the safety size of flap that can be perfused by a single free-style perforator, and the donor sites can be closed primarily. Each component part corresponds to a free-style perforator flap. The perforator vessels were reversely dissected, and small flaps of V-Y advancement, rotation and propeller pedicled with perforator vessels were formed (appropriate modification of flaps can be made according to actual anatomical perforator vessels). All flaps were transferred to the defect site and reassembled according to the preoperative design (film simulation) to repair the large wound or deep space after the extended resection of the tumor in the groin and adjacent organs. Meanwhile, the donor site was closed and sutured primarily. The color, temperature, capillary reaction of the skin flap were observed during the first 3 days after procedure, and appearance and function after repair were observed after long-term follow-up.Results:A total of 31 patients were enrolled, including 18 males and 13 females. The ages of the patients ranged from 48 to 82 years with an average of 66 years. The defect area of skin and soft tissue was 8.0 cm×10.0 cm-15.5 cm×20.0 cm, with an average of 12.0 cm×15.0 cm. A total of 65 flaps were harvested, including 32 propeller flaps, 18 rotating flaps and 15 V-Y advancement flaps. There were 3 cases with 3 flaps and 28 cases with 2 flaps. The average skin flap area was 12.0 cm×20.0 cm-5.0 cm×10.0 cm, with an average of 8.0 cm×13.0 cm, and the diameter of the pedicle perforator vessel was 0.5 mm-4.0 mm. The color, temperature and capillary reaction of the skin flap were normal during the first 3 days after operation. Too much tension resulted in congestion of the flap in one case and poor wound healing. The wound was treated with dressing change, and healed in two weeks. The patients were followed up for 3 months to 5 years, with an average of 1.5 years. 30 patients survived primarily. The postoperative appearance was good.Conclusions:The combination of multiple small free-style perforator flaps can repair the large skin and soft tissue defects of malignant tumors after extensive resection on the groin and its adjacent area, and the donor site can be closed primarily. This method is easy to operate and avoids micro anastomosis and skin grafting. It is a kind of repair approach for clinical reference.

ObjectiveTo observe the effect of aerobic exercise on core symptoms and executive function in children with attention deficit hyperactivity disorder (ADHD). MethodsFrom June, 2020 to December, 2021, 64 children with ADHD at outpatient in Dushu Lake Hospital were randomly divided into control group (n = 32) and observation group (n = 32). The control group sat down and watched the cartoon for 20 minutes, and the observation group performed cycling exercise while watching the cartoon, for twelve weeks. The core symptoms were assessed with Conners Parent Symptom Questionnaire (PSQ), while the inhibition, conversion and refresh functions were assessed with the psychological test software E-Prime 2.0 system. ResultsAfter twelve weeks of treatment, the PSQ factor scores decreased in the observation group (t > 4.775, P < 0.001), and were lower than that of the the control group (t > 3.184, P < 0.001). The response time and accuracy of inhibition, conversion, and refresh functions decreased in the observation group (t > 2.259, P < 0.05), and were lower than that of the control group (t > 2.007, P < 0.05). ConclusionAerobic exercise could reduce the core symptoms of poor attention and hyperactivity impulsivity, and improve the executive functioning in children with ADHD.

Objective:To explore the effect of exercise intervention on regulation of Toll-like receptor 4 (TLR4) signaling pathway in overweight and obese pregnant women.Methods:The cohort was based on a randomized controlled trial (RCT) carried out by the same research group in Peking University First Hospital from December 2014 to July 2016. Overweight and obese patients who delivered by elective cesarean section without pregnancy complications were recruited, among which 12 cases in the exercise group and 11 cases in the control group were selected. Real-time polymerase chain reaction, Western Blot, and Luminex experiments were used to compare the expression of TLR4-myeloid differentiation factor 8(MyD88)-nuclear factor-κB(NF-κB) pathway in peripheral blood mononuclear cell (PBMC), rectus abdominis muscle, omental adipose, and subcutaneous adipose, as well as the levels of inflammatory factors (TNF-α, IL-1β, IL-10) in plasma between the two groups. Two independent samples t-test, generalized estimating equation, Chi-square test, and Pearson correlation analysis were adopted for statistical analysis. Results:(1) The expression of inflammatory factors TNF-α and IL-1β in the exercise group showed a downward trend compared with the control in the second and third trimester, but none of the differences were statistically significant (all P>0.05). (2) The mRNA expression of TLR4, MyD88, and NF-κB and the protein expression of TLR4 and NF-κB in PBMC of the exercise group were significantly lower than those in the control group during pregnancy (TLR4 mRNA: 0.06±0.03 vs 0.10±0.04 in the second trimester, 0.05±0.02 vs 0.11±0.05 in the third trimester, χ2=8.07; MyD88 mRNA: 0.09±0.03 vs 0.11±0.03 in the second trimester, 0.10±0.04 vs 0.17±0.06 in the third trimester, χ2=5.81; NF-κB mRNA: 0.10±0.03 vs 0.17±0.08 in the second trimester, 0.08±0.03 vs 0.20±0.08 in the third trimester, χ2=14.71; TLR4 protein: 1.7±0.5 vs 1.9±0.8 in the second trimester, 1.7±0.4 vs 2.3±0.8 in the third trimester, χ2=5.83; NF-κB protein: 1.0±0.4 vs 1.5±0.4 in the second trimester, 1.2±0.3 vs 1.5±0.5 in the third trimester, χ2=4.73; all P<0.05). Moreover, the differences in the mRNA expression of TLR4, MyD88, and NF-κB and TLR4 protein expression in PBMC between the two groups gradually increased. (3) NF-κB in rectus abdominis and omental adipose tissue (0.04±0.02 vs 0.08±0.04, t=－3.72; 0.25±0.05 vs 0.63±0.21, t=－5.41; both P<0.05) and TLR4 and MyD88 in subcutaneous adipose tissue (0.12±0.03 vs 0.30±0.10, t=－5.30; 0.24±0.09 vs 0.44±0.08, t=－5.38; both P<0.05) were observed a decreased mRNA level in the exercise group compared with the control group. The protein level of MyD88 and NF-κB in omental adipose tissue and NF-κB in subcutaneous adipose tissue in the exercise group were significantly lower than those in the control group (1.1±0.5 vs 2.0±0.8, t=－3.15; 1.3±0.5 vs 2.0±0.9, t=－2.23; 1.2±0.5 vs 1.9±0.8, t=－2.80, all P<0.05). (4) The expressions of TLR4 and NF-κB mRNA ( r=0.453 and 0.485) in rectus abdominis muscle, NF-κB mRNA, TLR4 and MyD88 protein ( r=0.539, 0.437 and 0.527) in omental adipose in the two groups were positively correlated with the level of fasting blood glucose ( P<0.05). Conclusions:Regular exercise during pregnancy can down-regulate the expression and activation of the TLR4-MyD88-NFκB pathway in overweight and obese pregnant women. The expression of related factors along this pathway has a certain correlation with fasting blood glucose.
