Ying and wei qi is derived from the essence of water and grain， and is the basic material to maintain the normal life activities of the body. Ying and wei qi has the difference of nature of yin and yang or the clear and the turbid. When the relationship between ying and wei qi is out of order and in reverse disorder， it will lead to the occurrence of various diseases. Based on the analysis of the theory of "ying-wei disorder" in The Inner Canon of Yellow Emperor （《黄帝内经》）， this paper started from the perspective of the exuberance and debilitation， circulation and function of ying qi and wei qi， focused on the theoretical understanding that the change of deficiency and excess （"fall"） and the change of circulation （"move"）， and refined the core mechanism of "ying-wei disorder"， which is the depletion of ying qi and wei qi， stagnation of ying qi and wei qi， and disharmony of ying qi and wei qi， and finally summarized the syndrome identification and treatment method of supporting ying qi and assisting wei qi， promoting ying qi and moving wei qi， regulating ying qi and wei qi， and constructed the syndrome identification and treatment system for ying-wei disorder of malignant tumor in clinic.

Objective To investigate the incidence rate,clinical characteristics,and prognosis of neonatal stroke in Shenzhen,China.Methods Led by Shenzhen Children's Hospital,the Shenzhen Neonatal Data Collaboration Network organized 21 institutions to collect 36 cases of neonatal stroke from January 2020 to December 2022.The incidence,clinical characteristics,treatment,and prognosis of neonatal stroke in Shenzhen were analyzed.Results The incidence rate of neonatal stroke in 21 hospitals from 2020 to 2022 was 1/15 137,1/6 060,and 1/7 704,respectively.Ischemic stroke accounted for 75％(27/36);boys accounted for 64％(23/36).Among the 36 neonates,31(86％)had disease onset within 3 days after birth,and 19(53％)had convulsion as the initial presentation.Cerebral MRI showed that 22 neonates(61％)had left cerebral infarction and 13(36％)had basal ganglia infarction.Magnetic resonance angiography was performed for 12 neonates,among whom 9(75％)had involvement of the middle cerebral artery.Electroencephalography was performed for 29 neonates,with sharp waves in 21 neonates(72％)and seizures in 10 neonates(34％).Symptomatic/supportive treatment varied across different hospitals.Neonatal Behavioral Neurological Assessment was performed for 12 neonates(33％,12/36),with a mean score of(32±4)points.The prognosis of 27 neonates was followed up to around 12 months of age,with 44％(12/27)of the neonates having a good prognosis.Conclusions Ischemic stroke is the main type of neonatal stroke,often with convulsions as the initial presentation,involvement of the middle cerebral artery,sharp waves on electroencephalography,and a relatively low neurodevelopment score.Symptomatic/supportive treatment is the main treatment method,and some neonates tend to have a poor prognosis.

Cervical cancer is a gynecological malignant tumor with a high incidence in the world. With the insidious onset and lack of obvious symptoms and signs in the early stage， 13% of cervical cancer patients are diagnosed in the advanced stage of the disease， and the 5-year survival rate of metastatic cervical cancer is only 16.5%. So far， surgery and radiotherapy/chemotherapy are still the basic means for the treatment of cervical cancer. However， with the emergence of toxicity， drug resistance， and other side effects， there are still some limitations in the clinical application of these therapies. In recent years， natural compounds represented by polysaccharides have been found to have a significant anti-cervical cancer effect， which has attracted extensive attention from researchers in China and abroad. Widely distributed in the roots， stems， leaves， flowers， and fruits of higher plants， plant-based polysaccharides are important components of natural polysaccharides， as well as multimers with a complex structure and biological response regulators， which have been widely studied in the fields of cancer， cardiovascular， endocrine， and other diseases. This study reviewed the research on the anti-cervical cancer effect and mechanism of natural plant-derived polysaccharides by consulting the literature in the past 20 years to bring breakthroughs in the research and development of anti-cervical cancer new drugs. Through the literature review， the results indicated that natural plant-derived polysaccharides could exert anti-tumor effects by inhibiting cell proliferation， promoting apoptosis， inhibiting invasion and migration， promoting autophagy， arresting cell cycle of cervical cancer cells， regulating epithelial-mesenchymal transition （EMT）， resisting oxidative stress， inhibiting tumor angiogenesis， improving immunomodulatory activity， and regulating signaling pathways. It should be noted that in the current research on natural plant-derived polysaccharides against cervical cancer， the bioavailability of some natural polysaccharides is low and a considerable proportion of the research is limited to the in vitro experiment. Therefore， it is urgent to carry out more clinical experimental studies on the anti-cervical cancer of natural plant-based polysaccharides to obtain a more reliable theoretical and practical basis.

OBJECTIVE: This study aimed to assess the relationship between the body composition of children aged 3-5 years and breastfeeding status and duration. METHODS: The study was conducted using data from the National Nutrition and Health Systematic Survey for children 0-17 years of age in China (CNHSC), a nationwide cross-sectional study. Breastfeeding information and potential confounders were collected using standardized questionnaires administered through face-to-face interviews. The body composition of preschool children was measured using bioelectrical impedance analysis. A multivariate linear regression model was used to assess the relationship between breastfeeding duration and body composition after adjusting for potential confounders. RESULTS: In total, 2,008 participants were included in the study. Of these, 89.2% were ever breastfed and the median duration of breastfeeding was 12 months (IQR 7-15 months). Among children aged 3 years, the height-for-age Z-score (HAZ) for the ever breastfed group was lower than that for never breastfed group (0.12 vs. 0.42, P = 0.043). In addition, the weight-for-age Z-score (WAZ) of the ever breastfed group was lower than that of the never breastfed group (0.31 vs. 0.65, P = 0.026), and the WAZ was lower in children aged 4 years who breastfed between 12 and 23 months than in those who never breastfed. Compared to the formula-fed children, the fat-free mass of breastfed infants was higher for children aged 3 years (12.84 kg vs. 12.52 kg, P = 0.015) and lower for those aged 4 years (14.31 kg vs. 14.64 kg, P = 0.048), but no difference was detected for children aged 5 years (16.40 kg vs. 16.42 kg, P = 0.910) after adjusting for potential confounders. No significant difference was detected in the weight-for-height Z-score (WHZ), body mass index (BMI)-for-age Z-score (BAZ), fat-free mass index, and body fat indicators in the ever breastfed and never breastfed groups and among various breastfeeding duration groups for children aged 3-5 years. CONCLUSION No obvious associations were detected between breastfeeding duration, BMI, and fat mass indicators. Future prospective studies should explore the relationship between breastfeeding status and fat-free mass.

BACKGROUND: Butylphthalide (NBP) and edaravone (EDV) injection are common acute ischemic stroke medications in China, but there is a lack of large real-world safety studies on them. This study aimed to determine the incidence of adverse events, detect relevant safety signals, and assess the risk factors associated with these medications in real-world populations. METHODS: In this study, data of acute ischemic stroke patients were extracted from the electronic medical record database of six tertiary hospitals between January 2019 and August 2021. Baseline confounders were eliminated using propensity score matching. The drugs' safety was estimated by comparing the results of 24 laboratory tests standards on liver function, kidney function, lipid level, and coagulation function. The drugs' relative risk was estimated by logistic regression. A third group with patients who did not receive NBP or EDV was constructed as a reference. Prescription sequence symmetry analysis was used to evaluate the associations between adverse events and NBP and EDV, respectively. RESULTS: 81,292 patients were included in this study. After propensity score matching, the NBP, EDV, and third groups with 727 patients in each group. Among the 15 test items, the incidence of adverse events was lower in the NBP group than in the EDV group, and the differences were statistically significant. The multivariate logistic regression equation revealed that NBP injection was not a promoting factor for abnormal laboratory test results, whereas EDV had statistically significant effects on aspartate transaminase, low-density lipoprotein cholesterol and total cholesterol. Prescription sequence symmetry analysis showed that NBP had a weak correlation with abnormal platelet count. EDV had a positive signal associated with abnormal results in gamma-glutamyl transferase, alanine aminotransferase, aspartate aminotransferase, prothrombin time, and platelet count. CONCLUSIONS In a large real-world population, NBP has a lower incidence of adverse events and a better safety profile than EDV or other usual medications.

Osteoporotic vertebral compression fracture (OVCF) can lead to lower back pain and may be even accompanied by scoliosis, neurological dysfunction and other complications, which will affect the daily activities and life quality of patients. Vertebral augmentation is an effective treatment method for OVCF, but it cannot correct unbalance of bone metabolism or improve the osteoporotic status, causing complications like lower back pain, limited spinal activities and vertebral refracture. The post-operative systematic and standardized rehabilitation treatments can improve curative effect and therapeutic efficacy of anti-osteoporosis, reduce risk of vertebral refracture, increase patient compliance and improve quality of life. Since there still lack relevant clinical treatment guidelines for postoperative rehabilitation treatments following vertebral augmentation for OVCF, the current treatments are varied with uneven therapeutic effect. In order to standardize the postoperative rehabilitation treatment, the Spine Trauma Group of the Orthopedic Branch of Chinese Medical Doctor Association organized relevant experts to refer to relevant literature and develop the "Guideline for postoperative rehabilitation treatment following vertebral augmentation for osteoporotic vertebral compression fracture (2022 version)" based on the clinical guidelines published by the American Academy of Orthopedic Surgeons (AAOS) as well as on the principles of scientificity, practicality and advancement. The guideline provided evidence-based recommendations on 10 important issues related to postoperative rehabilitation treatments of OVCF.

Objective:To analyze the value of minute ventilation to carbon dioxide production slope (VE/VCO 2 slope) combined with peak systolic blood pressure (SBP) in predicting prognosis for patients with chronic heart failure (CHF). Methods:A total of 170 patients with CHF who visited the Cardiac Rehabilitation Center of Tongji Hospital Affiliated to Tongji University and completed cardiopulmonary exercise test from March 2007 to December 2018 were enrolled in the study. The clinical data, cardiopulmonary exercise testing results and follow-up information of patients were collected to explore the predictors of all-cause mortality in patients with CHF.Results:The median follow-up time was 647 (182-1 764) days. All-cause death occurred in 34 patients. Compared with surviving patients, the proportion of diabetes and angiotensin-converting enzyme inhibitor/angiotensin Ⅱ receptor blocker (ACEI/ARB) use in fatal patients was significantly higher ( P<0.01). The VE/VCO 2 slope and peak SBP*VE/VCO 2 in the fatal patients were significantly higher, and the peak oxygen consumption (peak VO 2) was lower than those in the surviving patients ( P<0.01). The areas under the receiver operating characteristic curve (AUC) of VE/VCO 2 slope and peak SBP*VE/VCO 2 in predicting all-cause mortality in patients with CHF were 0.648 ( P=0.008) and 0.681 ( P=0.001), respectively; the optimal thresholds were >40.95 ( P=0.008) and > 5 423.50 mmHg (1 mmHg=0.133 kPa, P=0.006), the sensitivity was 0.559 and 0.588, and the specificity was 0.728 and 0.735, respectively. Multivariate Cox regression analysis showed that after adjusting for age, gender, diabetes and ACEI/ARB use, VE/VCO 2 slope ( HR=2.12, P=0.036) and peak SBP*VE/VCO 2 ( HR=2.42, P=0.016) were independent risk factors for all-cause mortality in patients with CHF. Conclusion:Compared to the traditional index VE/VCO 2 slope, a novel index peak SBP* VE/VCO 2 provides a relatively better predictive value for all-cause death of CHF patients.

Objective: To investigate the correlation between heart rate index (HRI), systolic blood pressure(SBP) peak-to-SBPrest ratio (SBPR) and peak oxygen consumption (peakVO₂) in patients with chronic heart failure (CHF), and discuss the possibility of using HRI and SBPR collected during exercise to assess the exercise tolerance of CHF patients in the absence of gas analysis. Methods: In this cross-sectional study, a total of 547 patients with CHF who underwent cardiopulmonary exercise test(CPET) in Tongji Hospital Heart Rehabilitation Center Affiliated to Tongji University from March 2007 to December 2018 were collected retrospectively, focusing on their clinical data including age, gender, type of heart failure,BMI as well as data collected during their CPETs, such as peakVO₂, HRI and SBPR. Spearman univariate correlation analysis was used for statistical analysis, to unveil the correlations between peakVO₂ and those parameters, and multiple linear regression analysis was also conducted. Results: A total of 547 CHF patients conducting CPET were included in this research, of which 447 were male, at age of 63(56, 69). Univariate analysis indicates that HRI, SBPR and peakVO₂ showed significant positive correlation (r=0.323, 0.263, respectively, all P<0.001); Age and peak VO₂ showed significant negative correlation(r=-0.207, P<0.001); Male patients showed peakVO₂ higher than female(r=-0.229, P<0.001); PeakVO₂ of heart failure with reduced ejection fraction(HFrEF) was lower than heart failure with mid-range ejection fraction(HFmrEF)and heart failure with preserved ejection fraction(HFpEF) (r=0.181, P<0.001). Body mass index (BMI) had no significant correlation with peakVO₂ (P>0.05). Multivariate linear regression analysis showed that the HRI, SBPR were positively correlated with peakVO₂(t=7.68, 5.08, respectively, all P<0.05), while age and BMI showed negative correlation with peakVO₂(t=-5.43, -0.31, respectively, all P<0.05). PeakVO₂ of male was higher than female(t=-6.03, P<0.05), and peakVO₂ of HFrEF was lower than those of HFmrEF and HFpEF(t=3.17, 4.48, respectively, all P<0.05). A linear equation (F=33.52, adjusted R²=0.29) could be constructed: peakVO₂=10.65(male) or 8.53(female)+4.26HRI+3.31SBPR-0.07age-0.13BMI+0(HFrEF) or 1.05 (HFmrEF) or 1.62(HFpEF). Conclusion: HRI and SBPR are positively correlated with peakVO₂. In the absence of gas analysis, it is possible to apply HRI and SBPR during exercise to predict exercise tolerance in patients with CHF.

Abstract: Objective　This paper aims to explore the effect of live attenuated varicella vaccine on the sensitivity of tuberculin skin test(TST), and to provide reference for tuberculin skin test in the future. Methods　TST and emergency varicella vaccine were administered to students in grade one of a high school in Wuxi, Jiangsu province, who had both TB and varicella cases. Independent-samples t test was used to analyze the mean diameter of induration of TST in day 0, day 83 and day 195. The retrospective cohort study was used to analyze the effect of live attenuated varicella vaccine on TST. 　　Results　The mean induration diameter of 45 students who participated in three TST tests on day 0, day 83 and day 195 were analyzed by independent sample t test. On day 0, there was a difference in the mean diameter of TST induration between the unvaccinated and vaccinated groups(1.630±2.837 vs 5.818±4.530) (t=-3.692, P=0.001). On day 83, there was no difference in the mean diameter of TST induration between the two groups(0.001±0.001 vs 0.114±0.533) (t=-1.000, P=0.329). On day 195, there was a difference in the mean diameter of TST induration between the two groups(1.913±3.774 vs 5.023±5.126) (t=-2.309, P=0.026). Moreover, the retrospective cohort study showed that the mean diameter of TST induration changed more significantly after inoculation with varicella vaccine, RR=6.071, 95%CI (1.667-22.116), P<0.05; After inoculation with varicella vaccine, the mean diameter of TST test did not change significantly from day 0 to day 195 with no statistical significance RR=3.474, 95%CI (0.333-36.240), P>0.05. Conclusions　Live attenuated varicella vaccine may temporarily affect the sensitivity of tuberculin skin test.

Objective To study the functional antibody and protection effect against pneumonia disease after inoculation with PPV23 in HIV-infected adults. Methods In 2015, 63 HIV-infected adults were randomly selected in Hongkou District of Shanghai, and blood samples were collected before and one month after the inoculation of PPV23.Functional antibodies against 4 serotypes (19F, 19A, 23F, 6B) of Streptococcus pneumoniae were detected by opsonophagocyitosis killing assay (OPA).The incidence of pneumonia after PPV23 inoculation was also determined. Results The GMT of OPA antibodies against 4 serotypes 1 month after inoculation with PPV23 was significantly higher than that before inoculation in HIV-infected subjects.After inoculation, the triple growth rates of OPA antibodies against 4 serotypes in HIV-infected subjects were 50%-91.67%.The protection rate against pneumonia was 100% in 2 years after PPV23 inoculation in HIV-infected subjects when compared with same group before inoculation as well as the control group.The HIV-infected patients who received highly active antiretroviral therapy (HAART) or had CD4 count of≥300/μL showed better response in production of OPA antibodies and obtained protection against community-acquired pneumonia (CAP) after receiving PPV23. Conclusion Routine vaccination of PPV23 is recommended for HIV-infected patients with good basic conditions.
