Aging is an inevitable, physiological process of the human body, leading to deterioration in bodily function and increased susceptibility to various diseases. Effective endogenous therapeutic strategies for anti-aging and related diseases remain limited. Exercise confers multifaceted benefits to physical health by augmenting osteogenic and myogenic processes, enhancing cardiovascular and nervous system function, and attenuating chronic inflammation. Angiogenesis and lymphangiogenesis play pivotal roles in anti-aging, tissue repair, and immune response modulation, underscoring their potential as therapeutic targets for age-related diseases. Modulating angiogenic and lymphangiogenic pathways may provide a promising strategy for mitigating vascular decline and immune system dysfunction associated with aging. Exercise-induced endogenous angiogenesis and lymphangiogenesis can exert beneficial effects on physiological function, thereby representing a potential therapeutic paradigm for combating age-related decline and diseases. This review offers a thorough summary of the present knowledge regarding angiogenesis and lymphangiogenesis induced by exercise, encompassing the underlying mechanisms and the effects in different organs. In addition, it explores the potential of physical activity as a non-pharmacological intervention for anti-aging strategies and disease management, offering novel insights into the intersection of physical activity, aging, and disease progression.

Objective:Cardiac arrest (CA) represents a significant public health challenge, posing a substantial threat to individual health and survival. To enhance the survival rates of patients experiencing out-of-hospital cardiac arrest (OHCA), Baoan District in Shenzhen City has undertaken exploratory initiatives and practical interventions, yielding promising preliminary outcomes.Methods:1.Innovate emergency medical services by developing a "four-circle integration" system that connects to the hospital. This system encompasses the social emergency medical system, the out-of-hospital emergency medical system, the in-hospital emergency medical service system, and the intensive care treatment system. 2.Develop a comprehensive model for the construction of a social emergency medical training system, characterized by party leadership, government oversight, departmental coordination, professional guidance, technological support, and community involvement, termed the "Baonan Model." Additionally, establish evaluation criteria to assess the effectiveness of the social emergency medical training system in Baonan District; 3. Develop a cardiac arrest registration system and a social emergency medical training management system for Baonan District; 4. Enhance the proficiency in treatment techniques and the quality of cardiopulmonary resuscitation among emergency medical professionals; 5. Strengthen and advance the development of a "five-minute social rescue network" to address the critical "emergency window period." .Result:In Baonan District, 9.18% of the public is trained in emergency medical skills. The bystander CPR rate for OHCA is 26.11%, AED use is at 4.78%, the 30-day survival rate is 6.31%, and the discharge survival rate is 4.44%.Conclusion:The implementation of the aforementioned measures can substantially enhance the survival rate of patients experiencing OHCA at the time of discharge.

Objective To investigate the best evidence application of exercise prescription in patients with chronic heart failure in clinical practice and evaluate its effectiveness.Methods The best evidence of exercise prescription for patients with chronic heart failure was summarized,and the evidence-based practice plan was developed,and it was implemented in the cardiology department of a tertiary hospital in Zhejiang Province from August to October,2022.Nurses'exercise prescription knowledge-attitude-practice level,implementation rate of review indicators,the length of hospital stay,exercise endurance,daily living ability and grip strength of both groups before and after the intervention were compared.Results After the application of the best evidence,the score of knowledge dimension was(9.34±0.98)points;the score of attitude dimension was(63.29±1.37)points;the score of practice dimension was(25.49±1.51)points,which were statistically significant compared with the scores before the application of evidence(P<0.05).After the application of the best evidence,the implementation rate of 16 review indicators was higher than that before the application of evidence(P<0.001).The length of hospital stay in the evidence application group was shorter than that in the baseline examination group(Z=-2.610,P<0.001).After intervention,the exercise endurance,daily living ability and grip strength of patients in the evidence application group were improved compared with the baseline review group,and the difference was statistically significant(P<0.05).Conclusion After the application of the best evidence of exercise prescription in patients with chronic heart failure,it can improve the level of knowledge,attitude and practice of nurses on exercise prescription,standardize the compliance of nurses'exercise prescription,reduce the number of days in the hospital,and improve patients'exercise endurance,daily living ability and grip strength.

Objective:To explore the characteristics of weekly gestational weight gain (GWG) in women with obesity and its correlation with the risk of macrosomia.Methods:Clinical data of women with singleton pregnancy and pre-pregnancy body mass index (PPBMI) ≥28 kg/m 2 were retrospectively analyzed, from January 2014 to December 2019, in Beijing Obstetrics and Gynecology Hospital, Capital Medical University (Beijing Maternal and Child Health Care Hospital). The participants were divided into three groups based on their PPBMI: group A (28-<30 kg/m 2), group B (30-<32 kg/m 2), and group C (≥32 kg/m 2). The study compared the characteristics of GWG among the three groups, explored the correlation between the weekly weight gain during each gestational stage and the risk of macrosomia, and discussed the impacts of the GWG pattern in women with different PPBMI on the risk of macrosomia. Chi-square (or Fisher's exact), Kruskal-Wallis, and Mann-Whitney U tests were performed for statistical analysis. Multivariate logistic regression was used to analyze the impact of weekly weight gain in specific gestational stages on macrosomia. Results:(1) A total of 2 046 participants were included in the study, with 982 in group A, 588 in group B, and 476 in group C. For all of the 2 046 cases, the median PPBMI was 30.1 kg/m 2 (29.0-31.9 kg/m 2), GWG was 10.5 kg (7.3-14.0 kg), and neonatal birth weight was 3 520 g (3 215-3 816 g) with 60 (2.9%) ≥4 500 g, and the biggest baby weighed 5 580 g. Out of the births analyzed, macrosomia occurred in 318 cases (15.5%). (2) Among the three groups (A, B and C), the differences in maternal age [32.0 years (29.0-35.0 years), 32.0 years (29.0-35.0 years) and 32.0 years (29.0-34.0 years), H=6.58] and women with a history of type 2 diabetes mellitus [0.9% (9/982), 0.3% (2/588) and 1.9% (9/476), χ2=6.61] were statistically significant (all P<0.05). (3) The weekly weight gain in each group exhibited a gradual upward trend before 20-24 weeks, reached a plateau at 24-32 weeks, peaked at 32-36 weeks, and subsequently declined. The weekly weight gain of group A in the pre-pregnancy to 14 weeks [0.14 kg/week (0.00-0.25 kg/week)], 14 to 20 weeks [0.25 kg/week (0.17-0.42 kg/week)], and 20 to 24 weeks [0.38 kg/week (0.25-0.63 kg/week)] were higher than those of group B [0.07 kg/week (－0.03-0.21 kg/week), 0.25 kg/week (0.10-0.42 kg/week), and 0.38 kg/week (0.22-0.60 kg/week)], respectively ( Z value was－3.73,－2.16, and－2.01, all P<0.05). Likewise, the weekly weight gain of group B in the above three stages were all higher than those of group C [0.07 kg/week (－0.10-0.21 kg/week), 0.17 kg/week (0.05-0.33 kg/week), and 0.25 kg/week (0.08-0.50 kg/week)], respectively ( Z value was－2.55,－3.28, and－3.25, all P<0.05). (4) The risk of macrosomia increased with the weekly weight gain in specific gestational stages in different PPBMI groups. In group A, the stages correlated with increased risk were 14-20 weeks [adjusted odd ratio ( aOR)=2.669, 95% CI: 1.378-5.169] and 20-24 weeks ( aOR=1.764, 95% CI: 1.143-2.723), while the stages were 20-24 weeks ( aOR=2.149, 95% CI: 1.156-3.996) and 36 weeks until delivery ( aOR=1.888, 95% CI: 1.268-2.810) in group B, and pre-pregnancy to 14 weeks ( aOR=3.515, 95% CI: 1.158-10.665) and 14-20 weeks ( aOR=3.021, 95% CI: 1.058-8.628) in group C (all P<0.05). The risk of macrosomia increased when the weekly weight gain of both risk-related stages in group A ( aOR=2.255, 95% CI: 1.029-4.940) ≥50th percentile, and group B ( aOR=4.399, 95% CI: 1.017-19.023) ≥75th percentile, and for group C ( aOR=3.404, 95% CI: 1.004-11.543) when the weekly weight gain above 25th percentile (all P<0.05). Conclusions:Weekly GWG demonstrates an observable gradual acceleration pattern in women with obesity. Therefore, clinical attention should be directed towards monitoring fluctuations in the weekly weight gain in this population, as excessive weekly weight gain before 24 gestational weeks is associated with an elevated risk of macrosomia.

Objective:To evaluate the role of glutathione S-transferase μ1 (GSTM1) expression in mild hypothermia-induced mitigation of cerebral ischemia-reperfusion (I/R) injury and the relationship with microglial polarization.Methods:Eighty clean-grade healthy male Sprague-Dawley rats, aged 8 weeks, weighing 260-280 g, were divided into 4 groups ( n=20 each) using a random number table method: sham operation group (S group), cerebral I/R group (I/R group), mild hypothermia group (H group), and GSTM1 inhibitor + mild hypothermia group (IH group). The rat model of cerebral I/R injury was prepared using the filament occlusion method. The filament was removed to restore blood flow after the left middle cerebral artery was blocked for 2 h, and the rats′ brain and rectal temperature were maintained at 36-37 ℃ during the period. The vessels were only isolated and ligated without occlusion in S group. In H group, the entire body was wiped with 75% ethanol immediately after removing the filament, and the brain and rectal temperatures were maintained at 32-33 ℃ for 3 h, and the other procedures were the same as those previously described in I/R group. In IH group, GSTM1 inhibitor itaconic acid 8.6 mg/kg was intraperitoneally injected at 24 and 1 h before developing the model, and the other procedures were the same as those previously described in H group. Neurological deficits were evaluated using a modified neurological severity score (mNSS) at 24 h of reperfusion, and then the animals were sacrificed and the brains were removed for observation of cerebral infarction (by TTC staining) and for determination of the expression of GSTM1, M1-type microglial marker inducible nitric oxide synthase (iNOS), and M2-type microglial marker arginase-1 (Arg-1) (by Western blot), expression of GSTM1, iNOS and Arg-1 mRNA (quantitative real-time polymerase chain reaction) and contents of interleukin-6 (IL-6), IL-10, tumor necrosis factor-alpha (TNF-α) and transforming growth factor-beta (TGF-β) (by enzyme-linked immunosorbent assay). Results:Compared with S group, the mNSS and percentage of cerebral infarct size were significantly increased, and the expression of iNOS and Arg-1 protein and mRNA was up-regulated, the expression of GSTM1 and mRNA was down-regulated, and the contents of IL-6, TNF-α, IL-10 and TGF-β were increased in the other three groups ( P<0.05). Compared with I/R group and IH group, the mNSS and percentage of cerebral infarct size were significantly decreased, and the expression of iNOS protein and mRNA was down-regulated, the expression of Arg-1 protein and mRNA and GSTM1 was up-regulated, the contents of TNF-α and IL-6 were decreased, and the contents of TGF-β and IL-10 were increased in H group ( P<0.05). Conclusions:Up-regulated expression of GSTM1 is involved in mild hypothermia-induced mitigation of cerebral I/R injury, which is associated with inhibition of microglial polarization toward the M1 phenotype and promotion of polarization toward the M2 phenotype.

Objective:To analyze the maternal gestational weight gain (GWG) in women with pre-pregnancy obesity and its relationships with adverse pregnancy outcomes.Methods:This retrospective cohort study recruited 513 obese women (pre-pregnancy body mass index ≥30 kg/m 2) with singleton pregnancy in Beijing Obstetrics and Gynecology Hospital, Capital Medical University from January 2014 to December 2016. All participants were divided into three groups according to GWG: inadequate (GWG<5 kg, n=83), adequate (5 kg≤GWG≤9 kg, n=154), and excessive (GWG>9 kg, n=276) groups. Chi-square test, Fisher's exact test, Kruskal-Wallis test, and Mann-Whitney U test were used to compare the clinical data among the three groups, including GWG, pregnancy and neonatal outcomes, and labor process. Multivariate logistic regression was performed to analyze the association between maternal GWG and main pregnancy complications associated with obesity. Results:(1) Among 238 participants who gained more than 2.0 kg in the first trimester, 75.6% (180/238) were in the excessive group, while the rate was 34.9%(96/275) among the participants who gained less than 2.0 kg. (2) Postpartum body mass index retention (body mass index at six weeks postpartum minus pre-pregnancy body mass index) was the highest in the excessive group, followed by the adequate group and the inadequate group [0.8 kg/m 2 (0.0-2.2 kg/m 2) vs -0.7 kg/m 2 (-1.6 to 0.0 kg/m 2) vs -2.5 kg/m 2 (-3.2 to -1.5 kg/m 2), all P<0.05]. (3) The rates of primary cesarean section in the inadequate and adequate groups were 29.9% (20/67) and 32.6% (42/129), which were lower than that in the excessive group [43.3% (104/240), χ2=3.955 and 4.047, both P<0.05]. There were no statistically significant differences in the incidence of gestational hypertension, small/large for gestational age, or other major adverse pregnancy outcomes among the three groups (all P>0.05). The weight gain in the first trimester and before the oral glucose tolerance test were not correlated with gestational diabetes mellitus (GDM) ( aOR=1.038, 95% CI: 0.986-1.094, P=0.157; aOR=1.055, 95% CI: 1.000-1.113, P=0.051). The maternal weight gain of women with GDM during the 2nd, the 3rd, and the whole trimesters were lower than women without GDM respectively [3.0 kg (1.3-4.0 kg) vs 3.0 kg (2.0-5.0 kg), 4.0 kg (2.0-6.0 kg) vs 6.0 kg (4.0-8.0 kg), 9.0 kg (5.0-12.0 kg) vs 10.7 kg (7.5-15.0 kg); Z =-2.938, -6.352 and-4.104, all P<0.01]. Conclusions:In women with pre-pregnancy obesity, the first trimester is the critical window to control maternal GWG. GWG guidelines recommended by the Institute of Medicine could help to reduce the weight retention at six weeks postpartum, but couldn't reduce the risk of GDM, gestational hypertension, small/large for gestational age, or other major adverse pregnancy outcomes.

Objective To observe the relationship between different degree of cerebral edema and multiple organ dysfunction syndrome (MODS) of exertional heat stroke (EHS) patients. Methods The patients with EHS admitted to intensive care unit (ICU) of the 159th Hospital of PLA from June 2015 to June 2017 were enrolled. The electrical impedance perturbation coefficient (EIDC) of bilateral cerebral hemispheres were monitored at 2, 24 and 72 hours after the onset of the disease by BORN-BE non-invasive dynamic cerebral edema monitor, and the patients were divided into 9+ group, 10+ group and 11+ group according to the resistance of the measured mean impedance coefficients. Fasting venous blood of the patients were acquired after 2 hours and 72 hours of the disease, the levels of serum interleukin-1β (IL-1β), tumor necrosis factor-α (TNF-α), nitric oxide (NO), nitric oxide synthase (NOS), cardiac troponin I (cTnI), MB isoenzyme of creatine kinase (CK-MB), creatinine (Cr), β2-microglobulin (β2-MG), alanine aminotransferase (ALT) and aspartate transaminase (AST) were detected. The occurrence of MODS within 72 hours was recorded. Linear regression analysis of the correlation between EIDC and MODS was done. Results All 124 EHS patients were male; the age was (22.10±4.43) years. Among them, 20 in EIDC 9+ group, 61 in 10+ group, and 43 in 11+ group. There were no significant differences in the levels of IL-1β, TNF-α, NO, NOS, cTnI, CK-MB, Cr, β2-MG, ALT, AST after onset of 2 hours among different EPIC groups; all the indexes of 72 hours were significantly higher than those of 2 hours in each group; and the higher the EIDC, the more obvious increase of each index [EIDC 9+ group, 10+ group, 11+ group at 72 hours IL-1β (ng/L): 12.05±3.75, 18.49±7.94, 23.21±10.44;TNF-α (ng/L): 13.10±3.18, 18.92±7.23, 23.40±10.17; NO (μmol/L): 99.50±12.10, 111.41±17.75, 120.81±15.58;NOS (kU/L): 47.95±8.33, 56.70±12.12, 63.37±12.60; cTnI (ng/L): 92.75±20.92, 107.20±18.96, 117.30±14.53;CK-MB (U/L): 73.55±9.25, 83.23±13.19, 93.49±12.25; Cr (μmol/L): 165.30±9.41, 176.62±9.83, 180.09±10.14;β2-MG (mg/L): 16.45±2.68, 19.07±3.68, 22.05±3.93; ALT (U/L): 500.10±87.05, 563.90±91.28, 612.16±90.61, AST (U/L): 414.30±53.35, 470.51±73.83, 512.09±81.29, respectively, two-two comparison all P ＜ 0.05], the higher of the MODS incidence [40.00 % (8/20), 65.57% (40/61), 83.72% (36/43), x2= 12.199, P = 0.002]. Linear regression analysis showed that the degree of cerebral edema was positively correlated with the incidence of MODS (R2= 0.905, P = 0.002). Conclusion The higher of the EIDC, the more severe of cerebral edema, the stronger of the inflammatory reaction, and the more severe damage of heart, liver, kidney and other organs in EHS patients within 72 hours.

Objective To explore the correlation between endocrine therapy adherence and illness perception (IP) in breast cancer patients. Methods From January to June 2017, a total of 100 breast cancer patients treated in Oncology Department at a Class Ⅲ Grade A hospital in Daqing City of Heilongjiang Province were selected as subjects by convenience sampling. The endocrine therapy adherence and IP of patients were investigated with the breast cancer endocrine therapy adherence questionnaire and Brief Illness Perception Questionnaire (BIPQ). Pearson correlation and multiple linear regression were used to analyze the correlation between them. Results A total of 98 valid questionnaires were collected totally. Except for entry 3, 6 and 7, the scores on entries and total score of IP of patients were positively correlated with the endocrine therapy adherence (P<0.05). Except for entry 7, score of each entry and total score all entered the regression equation of adherence. Conclusions The IP of breast cancer patients has a correlation with the endocrine therapy adherence. We should raise the level of positive IP of patients by positive direction and intervention so as to improve endocrine therapy adherence of patients.

Objective To investigate the effects of writing to express positive emotion on well-being in single intrauterine fetal demise (sIUFD)women.Methods According to inclusion criteria,100 sIUFD women were recruited from January 2012 to January 2015.These candidates were randomly divided into control group and observation group with 50 members respectively.The patients of observation group were given conventional nursing instructions and provided with a written expression which written 30 -45 minutes a day and last 4 weeks.The patients of control group were given the conventional nursing instructions only.General Well-Being Schedule (GWB)was measured before and after the interventions.Results Before the interventions,the GWB score were no significant difference between two groups (P >0.05 ).After the intervention,the observation group GWB scores were (77.7 ±9.58),while the control group GWB scores were (70.3 ±8.45) (P <0.05).Conclusions The writing to express positive emotions can promote well-being in sIUFD women.
