ABSTRACT
Objective: To analyze the status of excess heart age and its risk factors among Chinese residents aged 35 to 64 years. Methods: The study subjects were Chinese residents aged 35 to 64 years who completed the heart age assessment by WeChat official account "Heart Strengthening Action" through the internet from January 2018 to April 2021. Information such as age, gender, body mass index (BMI), blood pressure, total cholesterol (TC), smoking history, and diabetes history was collected. The heart age and excess heart age were calculated according to the characteristics of individual cardiovascular risk factors and the heart aging was defined as excess heart age≥5 years and 10 years respectively. The heart age and standardization rate were calculated respectively based on the population standardization of the 7th census in 2021.CA trend test was used to analyze the changing trend of excess heart age rate and population attributable risk (PAR) was used to calculate the contribution of risk factors. Results: The mean age of 429 047 subjects was (49.25±8.66) years. The male accounted for 51.17% (219 558/429 047) and the excess heart age was 7.00 (0.00, 11.00) years. The excess heart age rate defined by excess heart age≥5 years and ≥10 years was 57.02% (the standardized rate was 56.83%) and 38.02% (the standardized rate was 37.88%) respectively. With the increase of the age and number of risk factors, the excess heart age rate of the two definitions showed an upward trend according to the result of the trend test analysis (P<0.001). The top two risk factors of the PAR for excess heart age were overweight or obese and smoking. Among them, the male was smoking and overweight or obese, while the female was overweight or obese and having hypercholesterolemia. Conclusion: The excess heart age rate is high in Chinese residents aged 35 to 64 years and the contribution of overweight or obese, smoking and having hypercholesterolemia ranks high.

Objective: To investigate the clinical value of observing perioperative changes of myeloperoxidase (MPO) and neutrophil elastase (NE) in coronary artery circulation in patients underwent valve replacement surgery. Methods: This perspective cohort study was performed in patients who underwent valvular surgery in Nanjing Drum Tower Hospital and Fuwai Hospital from June 2021 to June 2022. Patients were divided into perioperative myocardial injury group and age-, sex- and type of cardiac procedure-matched non-perioperative myocardial injury control group in the ratio of 1∶1. Perioperative myocardial injury was defined as cardiac troponin T (cTnT)>0.8 μg/L on the first postoperative day (POD), and the cTnT level on the second POD increased by more than 10% compared with the cTnT level on the first POD. During the operation, blood samples were collected from the coronary sinus before clamping ascending aorta, and within 5 minutes after de-clamping ascending aorta. Then, the levels of MPO and NE on coronary sinus were continuously measured. The death, severe ventricular arrhythmia, pneumonia, re-intubation, repeat cardiac surgery, extracorporeal membrane oxygenation (ECMO), intra-aortic balloon pump (IABP), continuous renal replacement therapy (CRRT), mechanical ventilation time and the duration of intensive care unit (ICU) were recorded. The levels of MPO and NE and the incidence of clinical outcomes were compared between the myocardial injury group and the control group. The independent risk factors of myocardial injury were analyzed by multivariate logistic regression. Results: A total of 130 patients were enrolled, aged (60.6±7.6) years old, with 59 males (45.4%). There were 65 patients in the myocardial injury group and 65 patients in the control group. During hospitalization, there was no death, ECMO, IABP and CRRT cases in both groups. Compared with the control group, the incidence of severe ventricular arrhythmia (13.8%(9/65) vs. 3.1%(2/65), P=0.03), pneumonia (20.0%(13/65) vs. 3.1%(2/65), P=0.03), re-intubation (6.2%(4/65) vs. 0, P=0.04) was significantly higher in myocardial injury group. The mechanical ventilation time (16.8(10.7, 101.7) h vs. 7.5(4.7, 15.1) h, P<0.01), and the duration of ICU (3.7(2.7, 18.9) vs. 2.7(1.8, 6.9)d, P<0.01) were significantly longer in myocardial injury group compared with the control group. There was no significant difference in the levels of MPO and NE in coronary sinus blood between the two groups before aortic clamping (all P>0.05). However, MPO ((551.3±124.2) μg/L vs. (447.2±135.9) μg/L, P<0.01) and NE ((417.0±83.1)μg/L vs. (341.0±68.3)μg/L, P<0.01) after 5 min aortic de-clamping were significantly higher in myocardial injury group than in the control group. Multivariate logistic regression analysis showed that the levels of NE (OR=1.02, 95%CI: 1.01-1.02, P<0.01), MPO (OR=1.00, 95%CI: 1.00-1.01, P=0.02) and mechanical ventilation time (OR=1.03, 95%CI: 1.01-1.06, P=0.02) were independent risk factors of myocardial injury in patients after surgical valvular replacement. Conclusion: Perioperative myocardial injury is related poor clinical outcomes, perioperative NE and MPO in coronary artery circulation are independent risk factors of perioperative myocardial injury in patients undergoing valve replacement surgery.

ABSTRACT
Brain metastases are the most common intracranial malignancies, and radiotherapy is an effective treatment of controlling the localized lesions. However, conventional radiotherapy techniques have their own shortcomings that limit the effectiveness of radiotherapy. Metastatic brain tumors are highly likely to recur or progress after treatment. Clinical studies have shown that arginine can penetrate the blood-brain barrier and subsequently improve the radiosensitization of metastatic brain tumors. In this article, the mechanisms underlying the effect of arginine on the radiosensitization of metastatic brain tumors by inhibition of tumor glycolytic metabolism, reduction of DNA damage repair and alteration of tumor hemodynamic parameters were reviewed, aiming to provide new ideas for clinical research and treatment of brain metastases.
ABSTRACT
Objective:To construct a core index system of job responsibilities for specialist trauma nurses tailored to the current trauma care system in China and provide a reference for trauma centers to set up specialist trauma nurses.Methods:Literature review and group discussion were used to develop the first draft of the core index system of job responsibilities for specialist trauma nurses. The Delphi method was used to conduct two rounds of consultation among 15 experts from 7 provinces or cities in China to determine the final draft. The two rounds of expert active coefficient, expert authority coefficient ( Cr), Kendal coefficient (Kendall′s W), and average value of the importance and variation coefficient ( CV) of each indicator were calculated. Results:In both rounds of consultations, the expert active coefficient was 100%, and the Cr was 0.953. In the second round of consultation, the Kendall′s W was 0.188 ( χ2 =155.29, P<0.001), and the average value of the importance of each indicator ranged from 4.27-5.00 points with the CV of less than 0.25 points. The final index system consisted of 7 first-level indicators and 49 second-level indicators. Conclusion:The core index system of job responsibilities for specialist trauma nurses is reasonable and comprehensive, which can provide guidance for setting up positions of specialist trauma nurses in China.
ABSTRACT
Objective:To assess the association of appendicular skeletal muscle mass(ASM) to fat mass(FM) ratio in early pregnancy with the risk of gestational diabetes mellitus (GDM).Methods:A total of 468 pregnant women who visited the Nutritional Department of Peking Union Medical College Hospital or Shunyi Maternal and Child Care Service Center in 2018 and 2019 were recruited. Detailed information and clinical data were collected. The body components were measured using the bioelectrical impedance analysis (BIA) method during early pregnancy (< 14 weeks) and the ASM to FM ratio was calculated. The patients were divided into the GDM group and normal glucose tolerance (NGT) group according to the results of the oral glucose tolerance test (OGTT) performed during 24-28 weeks. Binary logistics regression was used to explore the correlation between the ASM/FM ratio and the risk of GDM. The receiver operator characteristic (ROC) curve of subjects was used to evaluate the predictive value of ASM/FM ratio for GDM and the cut-off value was reported.Results:Compared to the NGT group, the ASM and FM in early pregnancy in the GDM group were significantly higher, while the ASM/FM ratio was significantly lower. A lower ASM/FM ratio in early pregnancy was one of the risk factors of developing GDM. The cut-off value of the ASM/FM ratio was 0.809. The area under the ROC curve for predicting GDM increased from 68.1% to 72.3% when ASM/FM ratio was incorporated, with a significant difference by Delong test ( P = 0.006). Conclusion:Inadequate muscle mass would increase the risk of GDM and the ASM/FM ratio could serve as a predictor of GDM.
ABSTRACT
【Objective】 To investigate the demographic characteristics and factors affecting the willingness to donate blood among potential donors in China, so as to improve the recruitment efficiency for blood donors. 【Methods】 Non-blood donors aged 18-55 were investigated by online questionnaire to collect data in terms of sociodemographic characteristics (10 items), blood donation related behaviors (9 items), blood donation willingness and factors affecting their willingness (5 items) from October to December 2022. Logistic regression analysis was utilized to investigate their demographic characteristics, and linear regression analysis was used to explore the factors influencing their donation willingness. 【Results】 Logistic regression analysis was conducted with potential blood donors as dependent variable, revealed that individuals who were not only-child 59.6%(334/560) vs 45.4%(98/216), had friends received blood transfusion 63.8%(238/373) vs 48.3%(194/402), had relatives with blood donation experience 63.0%(194/308) vs 51.0%(238/467), and received blood donation information from relatives or friends 64.4%(152/236) vs 51.9%(280/539) were more likely to be potential donors(P0.05). While subjective norms, convenience of blood donation and personal empathy had positive effects on willingness to donate blood, the regression coefficients were all greater than 0, which were 0.58, 0.14 and 0.34 (P<0.05). 【Conclusion】 To establish a wider blood donor community in China, recruitment strategies should be tailored to specific potential donor groups, and efforts should be made to strengthen promotion through relatives and friends, reinforce subjective norms, and provide more flexible options for blood donation time and location selection. In addition, incentive measures should be carefully selected to encourage blood donation.
ABSTRACT
Proteolysis targeting chimeras (PROTACs) is an innovative technique in targeted protein degradation. PROTACs is a heterobifunctional molecule which can bind to the E3 ligase and target protein to form a ubiquitination complex, resulting in the ubiquitin-proteasome system dependent degradation of target protein. PROTACs has been regarded as the promising method in drug discovery campaign, for its high commonality, potent degradation activity and unique selectivity profile. However, the catalytic mechanism also induces the uncontrollable protein degradation risk. Controllable PROTACs contain the responsive element in the molecular entity. In certain conditions, the element can be triggered to activate or terminate the degradation event. In this review, we will briefly summarize the strategies in controllable PROTACs and describe the representative examples according to the responsive mechanism. We hope this review could provide some insight into the further development of controllable PROTACs.
ABSTRACT
Objective:To investigate the effects and the possible mechanisms of Neiguan(PC6)and Gongsun(SP4)on the hypothalamic-pituitary-adrenal(HPA)axis in rats with functional dyspepsia(FD),thus to provide a theoretical basis for the clinical application of the Eight Confluent Points.Methods:Forty specific-pathogen-free Sprague-Dawley rats were divided into a blank group,a model group,an electroacupuncture(EA)group,and a Western medicine group by the random number table method,with 10 rats in each group.Rats in the blank group did not receive modeling or intervention.Rats in the other three groups were subjected to the FD with mood disorder model using the compound etiology modeling method.After the successful modeling,rats in the model group did not receive any interventions,rats in the Western medicine group received deanxit and mosaprid intervention,and those in the EA group received EA intervention on the ipsilateral Neiguan(PC6)and Gongsun(SP4)for 21 d.The sugar-water consumption rate was measured before the experiment and before and after interventions to assess the emotional status.The gastric emptying rate was measured after interventions to assess the gastrointestinal dynamics.The expression levels of hypothalamic corticotropin-releasing hormone(CRH),pituitary adrenocorticotropic hormone(ACTH),and adrenal corticosterone(CORT)were measured by enzyme-linked immunosorbent assay.Results:Compared with the blank group,the sugar-water consumption rate and the gastric emptying rate were decreased(P<0.01),and the hypothalamic CRH,pituitary ACTH,and adrenal CORT expression levels were increased(P<0.01)in the model group.Compared with the model group,the sugar-water consumption rate and the gastric emptying rate were significantly increased(P<0.01),while the expression levels of hypothalamic CRH,pituitary ACTH,and adrenal CORT were significantly decreased(P<0.01)in the EA group and the Western medicine group.The differences between the EA group and the Western medicine group were not statistically significant(P>0.05).Conclusion:The Eight Confluent Points Neiguan(PC6)and Gongsun(SP4)can improve the mood and gastrointestinal dynamics in FD rats,which may be achieved by down-regulating the hypothalamic CRH,pituitary ACTH,and adrenal CORT,as well as by correcting the HPA axis hyperfunction.
ABSTRACT
Objective: To investigate the analgesic mechanism of Tuina (Chinese therapeutic massage) by observing the effect of the N-methyl-D-aspartate receptor subunit 2B (NR2B)/postsynaptic density-95 (PSD-95) pathway on the dendritic structure of spinal cord dorsal horn in rats with lumbar disc herniation. Methods: Fifty Sprague-Dawley rats were randomly divided into a blank group, a model group, a Tuina group, a blocker agent group, and a blocker agent + Tuina group. The sciatic nerve chronic constriction injury (CCI) model was prepared by the sciatic nerve ligation method. From the 4th day after modeling, rats in the Tuina group and the blocker agent + Tuina group were subject to daily Tuina intervention, and those in the blocker agent group and the blocker agent + Tuina group were daily intrathecally injected with NR2B blocker agent (MK-801). The spontaneous pain score was used to observe the pain behavior of all rats. The expression levels of NR2B and downstream PSD-95 were measured by immunohistochemistry, and the dendritic structure changes were observed by Golgi staining for rat spinal cord dorsal horn after 14 d of continuous intervention. Results: Compared with the blank group, the degree of rat spontaneous pain after CCI was elevated in both the model and the Tuina groups (P<0.01) and was reduced in the Tuina group after the Tuina intervention compared with the model group (P<0.05). Compared with the model group, the rat spontaneous pain level after blocking NR2B was reduced in both the blocker agent group and the blocker agent + Tuina group (P<0.05). The NR2B and PSD-95 protein levels were significantly higher in the model group compared with the blank group (P<0.01); the total number of dendritic branches was increased (P<0.01), and the total dendritic length became longer (P<0.01) in the spinal cord dorsal horn. The rat NR2B and PSD-95 protein levels were significantly decreased in the Tuina group compared with the model group (P<0.01); the total dendritic branch number was reduced (P<0.01) and the total length was shortened (P<0.01) in the spinal cord dorsal horn. After blocking NR2B, the expression levels of NR2B and downstream PSD-95 protein were significantly lower in both the blocker agent group and the blocker agent + Tuina group compared to the model group (P<0.01). The total branch number was significantly reduced (P<0.01), and the total length was significantly shortened (P<0.01) of the dendrites in the spinal cord dorsal horn. Conclusion: Tuina may exert an analgesic effect by remodeling the dendritic structure in the spinal cord dorsal horn in rats with lumbar disc herniation, and its mechanism may be related to the inhibition of NR2B/PSD-95 signaling pathway.
ABSTRACT
Objective:To evaluate the efficacy and safety of belimumab combined with standard regimen in the treatment of active lupus nephritis (LN).Methods:It was a single-center, pre - and post-control retrospective study. The Data of active LN patients treated with belimumab combined with standard regimen in the Department of Nephrology, the First Affiliated Hospital of Sun Yat-sen University from June 1, 2020 to June 30, 2022 were collected for analyzing the renal response rate and adverse reactions after belimumab treatment.Results:A total of 17 patients were included, including 14 females (82.35%). The age of the first medication was (26.06±2.64) years old, the median time of illness before the use of belimumab was 24.00 (8.50, 48.50) months, and the recurrence times before the use of belimumab was (1.24±1.03) times. All the 17 patients underwent renal biopsy. The main pathological types were type IV in 11 cases (11/17), type Ⅲ+V in 2 cases (2/17), type IV+V in 3 cases (3/17), and type V in 1 case (1/17). The dose of glucocorticoids was (22.95±8.30) mg/d in 1 year before belimumab administration. In 12 patients with LN who completed 24 weeks of belimumab treatment plan, the 24-hour urinary protein showed a downward trend, and there was a statistically significant difference compared with the baseline at 24 week [0.49 (0.15, 2.19) g vs. 2.83 (1.14, 4.11) g, Z=-2.100, P=0.036]. Compared with the baseline, serum albumin at 24 week increased by 29.36%, with statistically significant difference [(34.50±3.34) g/L vs. (26.67±5.75) g/L, t=-3.840, P=0.030]. The systemic lupus erythematosus disease activity index-2K score continued to decline, with statistically significant difference compared with baseline at 24 week (5.00±3.02 vs. 12.00±2.82, t=6.163, P<0.001). The lymphocyte count increased, and the difference was statistically significant compared with the baseline at 24 week [0.72(0.28, 2.39)×10 9/L vs. 0.30(0.19,0.34)×10 9/L, Z=-2.073, P=0.038]. There was a statistically significant difference between the glucocorticoids dosage at 24 week and the average glucocorticoids dosage 1 year before treatment [(11.25±6.35) mg/d vs. (22.60±9.75) mg/d, t=4.225, P=0.003]. After observation of belimumab for (38.13±22.93) weeks, patients had a complete response rate of 64.71% (11/17), a partial response rate of 17.65% (3/17), and an overall response rate of 82.35% (14/17). Relapse occurred in 1 case.No infusion-related reactions occurred in 17 patients. During the treatment, a total of 5 adverse events occurred, including 2 cases of pulmonary infection, 1 case each of sepsis, upper respiratory tract infection, and cytomegalovirus infection, which all improved after treatment and the subsequent treatment was not affected. Conclusion:Belimumab combined with standard regimen can improve the response rate of LN, reduce the recurrence rate, reduce the dosage of glucocorticoids, and control the overall adverse events with good prognosis.
ABSTRACT
BACKGROUND@#Current guidelines recommend hepatocellular carcinoma (HCC) screening in high-risk populations. However, the ideal HCC screening interval and screening modality have not been determined. This study aimed to compare the screening efficacy among different modalities with various intervals.@*METHODS@#PubMed and other nine databases were searched through June 30, 2021. Binary outcomes were pooled using risk ratio (RR) with 95% confidence intervals (CIs). Survival rates were also pooled using RR with 95% CIs because most eligible studies only provided the number of survival patients instead of hazard ratio.@*RESULTS@#In all, 13 studies were included. Two random controlled trials (RCTs) and six cohort studies compared screening intervals for ultrasonography (US) screening and found no significant differences between shorter (3- or 4-month) and longer (6- or 12-month) screening intervals in terms of early HCC proportion, HCC significant mortality, 1-year survival rate; screening at 6-month interval significantly increased the proportion of early HCC (RR = 1.17, 95% confidence interval [CI]: 1.08-1.26) and prolonged the 5-year survival rate (RR = 1.39, 95% CI: 1.07-1.82) relative to the 12-month interval results. Three other RCTs and two cohort studies compared different screening modalities in cirrhosis or chronic hepatitis B, which indicated no statistical differences in the proportion of early HCC (RR = 0.89, 95% CI: 0.40-1.96) and HCC mortality (RR = 0.69, 95% CI: 0.23-2.09) between the biannual US and annual computed tomography (CT screening). Biannual US screening showed a lower proportion of early HCC than biannual magnetic resonance imaging (MRI) (RR = 0.60, 95% CI: 0.37-0.97) and biannual US combined with annual CT (RR = 1.31, 95% CI: 1.13-1.51) screening. The proportion of early HCC in the contrast-enhanced US group was slightly higher than that in the B-mode US (RR = 1.08, 95% CI: 1.00-1.23) group.@*CONCLUSIONS@#The evidence suggests that 6 months may be the best HCC screening interval for US screening. The effectiveness of CT and MRI is better than US during same screening intervals. However, MRI and CT are more expensive than US, and CT also can increase the risk of radiation exposure. The selection of CT or MRI instead of US should be carefully considered.@*REGISTRATION@#No. CRD42020148258 at PROSPERO website ( https://www.crd.york.ac.uk/PROSPERO/ ).

Objective:To investigate the current situation of occurrence of social isolation in maintenance hemodialysis patients and analyze its influencing factors, in order to provide a theoretical basis for the implementation of targeted interventions.Methods:The study was a cross-sectional study. A total of 315 dialysis patients in three hemodialysis centers in Xinjiang were selected by simple sampling method from October 2021 to March 2022, who were investigated using the general information questionnaire, Lubben-6 social network scale, International Physical Activity Questionnaire (sedentary behavior section), Patient Health Questionnaire 9-item scale (PHQ-9) and Frail Scale. Univariate analysis and binary Logistic regression analysis were used to explore the influencing factors affecting the social isolation of dialysis patients.Results:Social isolation was present in 28.89% (91/315) of maintenance hemodialysis patients, and binary Logistic regression analysis revealed that age (45-59 years old: OR=4.815, 95% CI 1.362-17.017;≥60 years old: OR=8.968, 95% CI 2.349-34.236), dialysis age ( OR=2.788, 95% CI 1.334-5.826), sedentary behavior ( OR=2.504, 95% CI 1.406-4.461), depression ( OR=2.095, 95% CI 1.179-3.722), and debilitation ( OR=2.043, 95% CI=1.062-3.933) were influencing factors of social isolation in maintenance hemodialysis patients (all P<0.05). Conclusions:The occurrence of social isolation in maintenance hemodialysis patients was closely associated with advanced age, high dialysis age, sedentary behavior, debilitation, and depressive status, suggesting that medical staff in hemodialysis centers can implement targeted interventions to prevent or improve the level of social isolation in patients based on relevant influencing factors.
ABSTRACT
Objective:To investigate the medication adherence and its influencing factors in young newly diagnosed pulmonary tuberculosis patients during different treatment periods, in order to provide a theoretical basis for formulating precise medication management strategies and thus improving the treatment success rate.Methods:A cross-sectional survey was conducted using a stratified random sampling method to select 283 young newly diagnosed pulmonary tuberculosis patients who visited and registered in the Kashgar region of Xinjiang from September 2021 to February 2022. The patients were divided into three groups according to the treatment time of receiving standard chemotherapy regimen: A (1-2 months of medication), B (3-4 months of medication), and C (5-6 months of medication), with 77, 89, and 117 cases, respectively. The clinical data of tuberculosis patients were collected by using the general information questionnaire,Eight-Item Morisky Medication Adherence Scale and Tuberculosis Medication Adherence Scale for tuberculosis patients.Results:Those who take medication well of three groups of young newly treated pulmonary tuberculosis patients were 93.5% (72/77), 89.9% (80/89), and 82.1% (96/117), respectively. The difference among the three groups was statistically significant ( χ2=6.23, P<0.05). Logistic regression analysis showed that social support was an influential factor for the 1st to 2nd month of medication ( OR=0.536, P<0.05); treatment confidence and psychological status were influential factors for the 3rd to 4th month of medication ( OR=0.668, 2.212, both P<0.05); comorbidity, social support, psychological status, and coping style were influential factors for the 5th to 6th month of medication ( OR values were 0.428 - 9.518, all P<0.05). Conclusions:The relevant factors that affect medication adherence vary among young newly diagnosed pulmonary tuberculosis patients at different stages of treatment. Accurate medication management strategies should be developed based on the influencing factors at each stage.
ABSTRACT
Objective:To explore the effects of Compound Huangbai Liquid coating combined with Xiaochuang Mixture on wound healing, clinical symptoms and inflammatory response in patients with perianal abscess surgery; To evaluate the clinical efficacy.Methods:Randomized controlled trial. 120 patients after perianal abscess surgery in the hospital from August 2021 to August 2022 were selected as the observation subjects, and they were divided into three groups by the random number table method, with 40 cases in each group. On the basis of routine anti-infection therapy, external TCM application group was given Compound Huangbai Liquid coating, oral TCM administration group was given oral Xiaochuang Mixture, and combined treatment group was treated with Compound Huangbai Liquid coating + Xiaochuang Mixture. The three groups were continuously treated for 15 days. TCM symptoms scores and VAS score were performed on the 2nd day, 7th day and 15th day after surgery, and the levels of IL-6 and TNF-α were detected by ELISA. The wound healing time and carrion shedding time of patients were observed and recorded, and the clinical efficacy was evaluated.Results:The scores of perianal secretions, granulation morphology and surrounding tissue edema and score of VAS decreased in the three groups at 7 days and 15 days after surgery compared with those at 2 days after surgery ( P<0.01), and with the extension of time, the scores of perianal secretions, granulation morphology and surrounding tissue edema and VAS score from the aspects of time-point effect ( F=21.69, 134.65, 19.27, 73.15) and between-group effect ( F=7.99, 98.79, 8.68, 10.71) were declined ( P<0.01), and there was an interaction effect between the decline degree and the treatment method ( F=9.78, 59.52, 11.29, 22.48, P<0.01). The carrion shedding time [(4.63±1.31) d vs. (6.22±2.14) d, (6.17±2.09) d, F=9.16] and healing time [(27.76±3.46) d vs. (30.27±4.11) d, (31.48±4.23) d, F=9.24] were earlier in combined treatment group than those in the external TCM application group and oral TCM administration group ( P<0.01). Serum levels of IL-6 and TNF-α in the three groups at 7 and 15 days after surgery were reduced compared with those at 2 days after surgery ( P<0.01), and with the extension of time, the levels of serum IL-6 and TNF-α in the three groups decreased from the aspects of time-point effect ( F=69.36, 38.76) and between-group effect ( F=21.81, 13.50) ( P<0.01), and there was an interaction effect between the decrease degree and treatment method ( F=28.46, 23.34, P<0.01). The total effective rate was 100.0% (40/40) in combined treatment group, 80.0% (32/40) in external TCM application group and 87.2% (34/39) in oral TCM administration group ( H=8.44, P=0.015). Conclusion:The combination of Compound Huangbai Liquid coating and Xiaochuang Mixture can reduce perianal secretions, improve granulation morphology, alleviate surrounding tissue edema and wound pain, promote wound healing, and reduce inflammatory response of patients with perianal abscess surgery.

Objective: To analyze the prevalence and the risk factors of fungal sepsis in 25 neonatal intensive care units (NICU) among preterm infants in China, and to provide a basis for preventive strategies of fungal sepsis. Methods: This was a second-analysis of the data from the "reduction of infection in neonatal intensive care units using the evidence-based practice for improving quality" study. The current status of fungal sepsis of the 24 731 preterm infants with the gestational age of <34+0 weeks, who were admitted to 25 participating NICU within 7 days of birth between May 2015 and April 2018 were retrospectively analyzed. These preterm infants were divided into the fungal sepsis group and the without fungal sepsis group according to whether they developed fungal sepsis to analyze the incidences and the microbiology of fungal sepsis. Chi-square test was used to compare the incidences of fungal sepsis in preterm infants with different gestational ages and birth weights and in different NICU. Multivariate Logistic regression analysis was used to study the outcomes of preterm infants with fungal sepsis, which were further compared with those of preterm infants without fungal sepsis. The 144 preterm infants in the fungal sepsis group were matched with 288 preterm infants in the non-fungal sepsis group by propensity score-matched method. Univariate and multivariate Logistic regression analysis were used to analyze the risk factors of fungal sepsis. Results: In all, 166 (0.7%) of the 24 731 preterm infants developed fungal sepsis, with the gestational age of (29.7±2.0) weeks and the birth weight of (1 300±293) g. The incidence of fungal sepsis increased with decreasing gestational age and birth weight (both P<0.001). The preterm infants with gestational age of <32 weeks accounted for 87.3% (145/166). The incidence of fungal sepsis was 1.0% (117/11 438) in very preterm infants and 2.0% (28/1 401) in extremely preterm infants, and was 1.3% (103/8 060) in very low birth weight infants and 1.7% (21/1 211) in extremely low birth weight infants, respectively. There was no fungal sepsis in 3 NICU, and the incidences in the other 22 NICU ranged from 0.7% (10/1 397) to 2.9% (21/724), with significant statistical difference (P<0.001). The pathogens were mainly Candida (150/166, 90.4%), including 59 cases of Candida albicans and 91 cases of non-Candida albicans, of which Candida parapsilosis was the most common (41 cases). Fungal sepsis was independently associated with increased risk of moderate to severe bronchopulmonary dysplasia (BPD) (adjusted OR 1.52, 95%CI 1.04-2.22, P=0.030) and severe retinopathy of prematurity (ROP) (adjusted OR 2.55, 95%CI 1.12-5.80, P=0.025). Previous broad spectrum antibiotics exposure (adjusted OR=2.50, 95%CI 1.50-4.17, P<0.001), prolonged use of central line (adjusted OR=1.05, 95%CI 1.03-1.08, P<0.001) and previous total parenteral nutrition (TPN) duration (adjusted OR=1.04, 95%CI 1.02-1.06, P<0.001) were all independently associated with increasing risk of fungal sepsis. Conclusions: Candida albicans and Candida parapsilosis are the main pathogens of fungal sepsis among preterm infants in Chinese NICU. Preterm infants with fungal sepsis are at increased risk of moderate to severe BPD and severe ROP. Previous broad spectrum antibiotics exposure, prolonged use of central line and prolonged duration of TPN will increase the risk of fungal sepsis. Ongoing initiatives are needed to reduce fungal sepsis based on these risk factors.

OBJECTIVE@#To investigate the effects of umbilical moxibustion therapy on phobic behavior and the contents of norepinephrine (NE), dopamine (DA) and 5-hydroxytryptamine (5-HT) in different brain regions of the stress-model rats and explore the potential mechanism of umbilical moxibustion on phobic behavior.@*METHODS@#Among 50 Wistar male rats, 45 rates were selected and randomly divided into a control group, a model group and an umbilical moxibustion group, 15 rats in each one; and the rest 5 rats were used for preparing the model of electric shock. The bystander electroshock method was adopted to prepare phobic stress model in the model group and the umbilical moxibustion group. After modeling, the intervention with umbilical moxibustion started in the umbilical moxibustion group, in which, the ginger-isolated moxibustion was applied at "Shenque" (CV 8), once daily, 2 cones for 20 min each time, for consecutively 21 days. After modeling and intervention completed, the rats in each group were subjected to the open field test to evaluate the state of fear. After intervention, the Morris water maze test and fear conditioning test were performed to evaluate the changes in learning and memory ability and the state of fear. Using high performance liquid chromatography (HPLC), the contents of NE, DA and 5-HT in the hippocampus, prefrontal cortex and hypothalamus were determined.@*RESULTS@#Compared with the control group, the horizontal and vertical activity scores were lower (P<0.01), the number of stool particles was increased (P<0.01), the escape latency was prolonged (P<0.01), the times of target quadrant were reduced (P<0.01), and the freezing time was prolonged (P<0.05) in the rats of the model group. The horizontal and vertical activity scores were increased (P<0.05), the number of stool particles was reduced (P<0.05), the escape latency was shortened (P<0.05, P<0.01), the times of target quadrant were increased (P<0.05), and the freezing time was shortened (P<0.05) in the rats of the umbilical moxibustion group when compared with the model group. The trend search strategy was adopted in the control group and the umbilical moxibustion group, while the random search strategy was used in rats of the model group. Compared with the control group, the contents of NE, DA and 5-HT in the hippocampus, prefrontal cortex and hypothalamus were reduced (P<0.01) in the model group. In the umbilical moxibustion group, the contents of NE, DA and 5-HT in the hippocampus, prefrontal cortex and hypothalamus were increased (P<0.05, P<0.01) when compared with the model group.@*CONCLUSION@#Umbilical moxibustion can effectively relieve the state of fear and learning and memory impairment of phobic stress model rats, which may be related to the up-regulation of contents of brain neurotransmitters, i.e. NE, DA, and 5-HT.

Objective: To analyze the status of excess heart age and its risk factors among Chinese residents aged 35 to 64 years. Methods: The study subjects were Chinese residents aged 35 to 64 years who completed the heart age assessment by WeChat official account"Heart Strengthening Action"through the internet from January 2018 to April 2021. Information such as age, gender, body mass index (BMI), blood pressure, total cholesterol (TC), smoking history, and diabetes history was collected. The heart age and excess heart age were calculated according to the characteristics of individual cardiovascular risk factors and the heart aging was defined as excess heart age≥5 years and 10 years respectively. The heart age and standardization rate were calculated respectively based on the population standardization of the 7th census in 2021.CA trend test was used to analyze the changing trend of excess heart age rate and population attributable risk (PAR) was used to calculate the contribution of risk factors. Results: The mean age of 429 047 subjects was 49.25±8.66 years. The male accounted for 51.17% (219 558/429 047) and the excess heart age was 7.00 (0.00, 11.00) years. The excess heart age rate defined by excess heart age≥5 years and≥10 years was 57.02% (the standardized rate was 56.83%) and 38.02% (the standardized rate was 37.88%) respectively. With the increase of the age and number of risk factors, the excess heart age rate of the two definitions showed an upward trend according to the result of the trend test analysis (P<0.001). The top two risk factors of the PAR for excess heart age were overweight or obese and smoking. Among them, the male was smoking and overweight or obese, while the female was overweight or obese and having hypercholesterolemia. Conclusion: The excess heart age rate is high in Chinese residents aged 35 to 64 years and the contribution of overweight or obese, smoking and having hypercholesterolemia ranks high.
ABSTRACT
OBJECTIVE@#To explore the effect of abnormal miRNA expression on the proliferation of pediatric acute lymphoblastic leukemia (ALL) cells and its related mechanism.@*METHODS@#15 children with ALL and 15 healthy subjects were collected from the Second Affiliated Hospital of Hainan Medical University from July 2018 to March 2021. MiRNA sequencing was performed on their bone marrow cells, and validated using qRT-PCR. MiR-1294 and miR-1294-inhibitory molecule (miR-1294-inhibitor) were transfected into Nalm-6 cells, and the proliferation of Nalm-6 cells was detected by CCK-8 and colony formation assays. Western blot and ELISA were used to detect apoptosis of Nalm-6 cells. Biological prediction of miR-1294 was performed to find the target gene, which was verified by luciferase reporter assay. Si-SOX15 was transfected into Nalm-6 cells, Western blot was used to detect the expression of Wnt signaling pathway-related proteins and to verify the effect of si-SOX15 on the proliferation and apoptosis of Nalm-6 cells.@*RESULTS@#Compared with healthy subjects, 22 miRNAs were significantly upregulated in bone marrow cells of ALL patients, of which miR-1294 was the most significantly upregulated. In addition, the expression level of SOX15 gene was significantly reduced in bone marrow cells of ALL patients. Compared with the NC group, the miR-1294 group showed increased protein expression levels of Wnt3a and β-catenin, faster cell proliferation, and more colony-forming units, while caspase-3 protein expression level and cell apoptosis were reduced. Compared with the NC group, the miR-1294-inhibitor group showed reduced protein expression levels of Wnt3a and β-catenin, slower cell proliferation, and fewer colony-forming units, while caspase-3 protein expression level was increased and apoptosis rate was elevated. miR-1294 had a complementary base-pair with the 3'UTR region of SOX15 , and miR-1294 directly targeted SOX15 . The expression of miR-1294 was negatively correlated with SOX15 in ALL cells. Compared with the si-NC group, the si-SOX15 group showed increased protein expression levels of Wnt3a and β-catenin, accelerated cell proliferation, and decreased caspase-3 protein expression level and cell apoptosis rate.@*CONCLUSION@#MiR-1294 can target and inhibit SOX15 expression, thus activating the Wnt/β-Catenin signaling pathway to promote the proliferation of ALL cells, inhibit cell apoptosis, and ultimately affect the disease progression.
