RESUMEN
ObjectiveTo explore the therapeutic effect of Huangliansan on atopic dermatitis (AD) model mice induced by 2, 4-dinitrochlorobenzene (DNCB). MethodA total of 42 male BALB/c mice were randomly divided into normal group, model group, hydrocortisone group, low, medium, and high-dose groups (0.3, 0.6, 1.2 g·kg-1) of Huangliansan oil, and water extract group (0.6 g·kg-1) of Huangliansan. In addition to the normal group, DNCB was applied on the back of mice in other groups to establish the AD model. On the 15th day after DNCB stimulation, each group was given the corresponding drug or solvent, and the changes in skin lesions, dermatitis score, and frequency of scratching were observed and recorded. Hematoxylin-eosin (HE) staining was used to observe the histopathological changes in the skin and spleen. Real-time fluorescent quantitative polymerase chain reaction (Real-time PCR) was used to detect mRNA levels of filaggrin (FLG), lorophane (LOR), and involucrin (IVL) in skin, as well as immunoglobulin E (lgE), interleukin-4 (IL-4), interleukin-6 (IL-6), interleukin-1β (IL-1β), tumor necrosis factor-α (TNF-α), and interferon-γ (IFN-γ) in spleen. ResultCompared with the normal group, the model group showed symptoms of skin swelling and scab, and the score of dermatitis, the frequency of scratching, and the spleen index were increased (P<0.05). The expression levels of FLG, LOR, and IVL in skin tissue were significantly decreased (P<0.01), and the mRNA expressions of IgE, IL-4, IL-6, IL-1β, and TNF-α in the spleen were significantly increased, while the expression level of IFN-γ was significantly decreased (P<0.01). Compared with the model group, the symptoms of skin erythema, scaly, and scab of mice in each drug group were alleviated to varying degrees, and the score of dermatitis, the frequency of scratching, and the spleen index were decreased (P<0.05, P<0.01). In addition, the expression levels of FLG, LOR, and IVL in the skin of mice in the drug group were increased (P<0.05, P<0.01), and the mRNA expression of IgE, IL-4, IL-6, IL-1β, and TNF-α in spleen were decreased. IFN-γ was increased (P<0.05, P<0.01), and the lesions of the skin and spleen were improved to varying degrees. The medium-dose group of Huangliansan oil and hydrocortisone group had the most obvious manifestations (P<0.05, P<0.01). The indexes in the medium-dose group of Huangliansan oil were better than those in the water extract group of Huangliansan. ConclusionHuangliansan may improve the expression level of skin barrier protein, inhibit the expression of helper T cell 2 (Th2)-related inflammatory factors, increase the expression of helper T cell 1 (Th1) inflammatory factors, restore the skin barrier function and Th1/Th2 balance in the spleen, regulate the inflammatory response in the spleen of AD mice, and thus relieve AD. Huangliansan oil is more effective than water extract.

OBJECTIVES@#To explore the association between assisted reproductive technology (ART) and birth weight discordance in twins (BWDT).@*METHODS@#A retrospective analysis was conducted on twin infants born between January 2011 and December 2020 at the Third Affiliated Hospital of Guangzhou Medical University, with complete basic birth data. The impact of ART on the occurrence of BWDT was identified by the multivariate logistic regression analysis.@*RESULTS@#A total of 3 974 pairs of twins were included, with 1 431 conceived naturally and 2 543 through ART. Neonates in the ART group had higher birth weights than those in the naturally conceived group (P<0.001). The incidence of BWDT was lower in the ART group compared to the naturally conceived group (16.17% vs 21.09%, P<0.001). The multivariate logistic regression analysis, adjusting for confounding factors such as maternal age, parity, pre-pregnancy body mass index, gestational diabetes, hypothyroidism, gestational age, and chorionic properties, showed no significant difference in the risk of BWDT between the ART and naturally conceived groups (P>0.05).@*CONCLUSIONS@#ART is not associated with the risk of BWDT.

OBJECTIVE@#To investigate the outcome of lateral femoral notch (LFN) after early anterior cruciate ligament (ACL) reconstruction and evaluate the recovery of knee joint function after the operation.@*METHODS@#The clinical data of 32 patients who underwent early ACL reconstruction from December 2015 to December 2019 were retrospectively analyzed. The study included 18 males and 14 females, aged 16 to 54 years old, with an average age of (25.39±2.82) years. The body mass index (BMI) of the patients ranged from 20 to 30 kg/cm2, with an average of (26.15±3.09) kg/cm2. Among them, 6 cases were caused by traffic accidents, 19 by exercise, and 7 by the crush of heavy objects. MRI of all patients showed LFN depth was more than 1.5 mm after injury, and no intervention for LFN was performed during surgery. Preoperative and postoperative depth, area, and volume of LFN defects were observed by MRI data. International Cartilage Repair Society (ICRS) score, Lysholm score, Tegner activity levels, and knee injury and osteoarthritis outcome score (KOOS) were analyzed before and after the operation.@*RESULTS@#All patients were followed up from 2 to 6 years with an average of (3.28±1.12) years. There was no significant difference in the defect depth of LFN from (2.31±0.67) mm before the operation to (2.53±0.50) mm at follow-up (P=0.136). The defect area of LFN was decreased from (207.55±81.01)mm2 to (171.36±52.69)mm2 (P=0.038), and the defect volume of LFN was decreased from (426.32±176.54) mm3 to (340.86±151.54)mm3 (P=0.042). The ICRS score increased from (1.51±0.34) to (2.92±0.33) (P<0.001), the Lysholm score increased from (35.37±10.54) to (94.46±8.45) (P<0.001), and the Tegner motor score increased from (3.45±0.94) to (7.56±1.28), which was significantly higher than that of the preoperative data (P<0.001). The KOOS score of the final follow-up was 90.42±16.35.@*CONCLUSION@#With the increase of recovery time after anterior cruciate ligament reconstruction, the defect area and volume of LFN decreased gradually, but the defect depth remained unchanged. The knee joint function of the patients significantly improved. The cartilage of the LFN defect improved, but the repair effect was not good.

Background Few studies have been conducted on the associations of dietary habits with the risks of high normal blood pressure and hypertension in employees of chemical companies in northwest China. Objective To understand the excess intakes of red meat, offal, and salt, the current status of high normal blood pressure and hypertension detection among employees of a large chemical company in Gansu, China, and to analyze the relationships between different dietary habits and the risks of high normal blood pressure and hypertension. Methods A large state-owned chemical enterprise in Gansu Province was selected and 914 employees were recruited by age-stratified random sampling. A set of questionnaires and health examination were adopted for the survey. χ2 test was used to compare dietary habits. A logistic regression model was used to analyze the relationships between different dietary habits and the risks of high normal blood pressure and hypertension in the chemical enterprise employees after including the factors significantly different in the χ2 test. Results A total of 914 workers completed the survey. Significant differences were found in the distribution of normal blood pressure, high normal blood pressure, and hypertension among the participants grouped by gender, age, body mass index (BMI), and family history of hypertension (P < 0.001). The excess intake rates of red meat, offal, and salt were 25.4%, 29.0%, and 62.1%, respectively. Significant differences were found in the distribution of normal blood pressure, high normal blood pressure, and hypertension among the participants grouped by intakes of meat, offal, and salt (P < 0.001). The highest positive rate of high normal blood pressure was detected in the workers with excess intakes of offal and salt (P < 0.001). The prevalence rate of hypertension increased with higher intakes of red meat, offal, and salt (P < 0.001). After adjusting for gender, age, BMI, family history of hypertension, and other factors, the results of logistic regression showed that the risks of high normal blood pressure and hypertension in workers with excess red meat intake were 1.55 (95%CI: 1.00, 2.38) times and 2.88 (95%CI: 1.63, 5.07) times higher than those in workers with low red meat intake respectively. The risks of high normal blood pressure and hypertension in workers with excess offal intake were 1.75 (95%CI: 1.12, 2.72) times and 1.87 (95%CI: 1.01, 3.44) times higher than those in workers with no offal intake respectively. The risks of high normal blood pressure and hypertension in workers with excess salt intake were 1.80 (95%CI: 1.22, 2.65) times and 2.59 (95%CI: 1.63, 4.11) times higher than those in workers with moderate salt intake, respectively. Conclusion Excessive intakes of red meat, offal or salt are common among the chemical enterprise workers. Excess intakes of red meat, offal, and salt are risk factors for both high normal blood pressure and hypertension. The northwest chemical enterprise should further advocate a healthy and reasonable diet among employees, and propose to reduce the intakes of red meat, offal, and salt.
RESUMEN
Objective To systematically evaluate the application value of next-generation sequencing technology in the etiological diagnosis of patients with sepsis.Methods Databases such as PubMed,Embase,Web of Science,The Cochrane Library,VIP,CNKI,WanFang Data Knowledge Service platform and SinoMed were searched from January 2018 to September 2022.The positive rate of sepsis detection,pathogen detection time,virus detection rate,28 days mortality rate and length of stay in intensive care unit(ICU)were com-pared between next-generation sequencing technology and traditional etiological detection method.Meta-analysis was performed using Review Manager 5.4.1 software,and funnel plot was pictured to analyze the publication bias of the included literatures.Results A total of 18 literatures were included.The results of Meta-analysis showed that the positive rate of next-generation sequencing group was 72.3%(1403/1941),which was significantly higher than that of the traditional etiological detection group[28.4%(556/1958),OR=7.03,95%CI:4.52-10.95,P<0.01];the time of pathogen detection was significantly lower than that of traditional etiological detec-tion group(OR=-34.22,95%CI:-41.95--26.48,P<0.01);the virus detection rate was significantly higher than that of tradi-tional etiological detection group(OR=57.82,95%CI:19.27-173.46,P<0.01);the length of stay in ICU was significantly lower than that of traditional etiological detection group(WMD=-9.37,95%CI:-16.28--2.46,P<0.01);there was no significant difference in 28 days mortality between the two groups(OR=0.43,95%CI:0.02-8.47,P=0.58).Conclusion Compared with tra-ditional etiological detection methods,next-generation sequencing technology can improve the positive rate of pathogen detection and vi-rus detection in sepsis patients,shorten the time of pathogen physical examination and the length of stay in ICU,and has higher applica-tion value for the diagnosis and treatment of sepsis.
RESUMEN
At present, there have been many clinical trials and systematic reviews/Meta-analysis proving the good clinical efficacy of Shufeng Jiedu Capsules in the treatment of respiratory diseases, while comprehensive discussion is still required. This article overviews and analyzes the systematic reviews/Meta-analysis of Shufeng Jiedu Capsules to provide evidence support for clinical practice. The systematic reviews/Meta-analysis of Shufeng Jiedu Capsules were searched from CBM, Wanfang, CNKI, VIP, PubMed, EMbase and Cochrane Library. The AMSTAR 2 scale and GRADE system were respectively employed for the evaluation of methodological quality and the grading of evidence quality. Finally, 8 systematic reviews/Meta-analysis published during 2018-2021 were included for analysis. The diseases involved include acute exacerbation of chronic obstructive pulmonary disease, community-acquired pneumonia, acute tonsillitis, acute exacerbation of chronic bronchitis and acute upper respiratory tract infection. The number of included RCTs studies ranged from 8 to 25. The results showed that Shufeng Jiedu Capsules combined with western medicine routine had better therapeutic effect than the latter alone in the treatment of the above five diseases. The reported adverse reactions caused by Shufeng Jiedu Capsules were mainly gastrointestinal discomforts such as mild nausea, diarrhoea and vomiting, with low incidence and mild symptoms, which can be relieved by drug withdrawal. The methodological quality of the included studies was extremely low, and the outcome indicators were mainly of low and very low grades. The efficacy and safety of Shufeng Jiedu Capsules in the clinical treatment of diseases still need to be verified based on more high-quality studies. The relevant clinical research and systematic review/Meta-analysis should pay more attention to methodological quality and reporting standards and strengthen the scientificity of research.

OBJECTIVES@#To investigate the clinical treatment outcomes and the changes of the outcomes over time in extremely preterm twins in Guangdong Province, China.@*METHODS@#A retrospective analysis was performed for 269 pairs of extremely preterm twins with a gestational age of <28 weeks who were admitted to the department of neonatology in 26 grade A tertiary hospitals in Guangdong Province from January 2008 to December 2017. According to the admission time, they were divided into two groups: 2008-2012 and 2013-2017. Besides, each pair of twins was divided into the heavier infant and the lighter infant subgroups according to birth weight. The perinatal data of mothers and hospitalization data of neonates were collected. The survival rate of twins and the incidence rate of complications were compared between the 2008-2012 and 2013-2017 groups.@*RESULTS@#Compared with the 2008-2012 group, the 2013-2017 group (both the heavier infant and lighter infant subgroups) had lower incidence rates of severe asphyxia and smaller head circumference at birth (P<0.05). The mortality rates of both of the twins, the heavier infant of the twins, and the lighter infant of the twins were lower in the 2013-2017 group compared with the 2008-2012 group (P<0.05). Compared with the 2008-2012 group, the 2013-2017 group (both the heavier infant and lighter infant subgroups) had lower incidence rates of pulmonary hemorrhage, patent ductus arteriosus (PDA), periventricular-intraventricular hemorrhage (P-IVH), and neonatal respiratory distress syndrome (NRDS) and a higher incidence rate of bronchopulmonary dysplasia (P<0.05).@*CONCLUSIONS@#There is a significant increase in the survival rate over time in extremely preterm twins with a gestational age of <28 weeks in the 26 grade A tertiary hospitals in Guangdong Province. The incidences of severe asphyxia, pulmonary hemorrhage, PDA, P-IVH, and NRDS decrease in both the heavier and lighter infants of the twins, but the incidence of bronchopulmonary dysplasia increases. With the improvement of diagnosis and treatment, the multidisciplinary collaboration between different fields of fetal medicine including prenatal diagnosis, obstetrics, and neonatology is needed in the future to jointly develop management strategies for twin pregnancy.

OBJECTIVES@#To investigate the incidence of extrauterine growth retardation (EUGR) and its risk factors in very preterm infants (VPIs) during hospitalization in China.@*METHODS@#A prospective multicenter study was performed on the medical data of 2 514 VPIs who were hospitalized in the department of neonatology in 28 hospitals from 7 areas of China between September 2019 and December 2020. According to the presence or absence of EUGR based on the evaluation of body weight at the corrected gestational age of 36 weeks or at discharge, the VPIs were classified to two groups: EUGR group (n=1 189) and non-EUGR (n=1 325). The clinical features were compared between the two groups, and the incidence of EUGR and risk factors for EUGR were examined.@*RESULTS@#The incidence of EUGR was 47.30% (1 189/2 514) evaluated by weight. The multivariate logistic regression analysis showed that higher weight growth velocity after regaining birth weight and higher cumulative calorie intake during the first week of hospitalization were protective factors against EUGR (P<0.05), while small-for-gestational-age birth, prolonged time to the initiation of total enteral feeding, prolonged cumulative fasting time, lower breast milk intake before starting human milk fortifiers, prolonged time to the initiation of full fortified feeding, and moderate-to-severe bronchopulmonary dysplasia were risk factors for EUGR (P<0.05).@*CONCLUSIONS@#It is crucial to reduce the incidence of EUGR by achieving total enteral feeding as early as possible, strengthening breastfeeding, increasing calorie intake in the first week after birth, improving the velocity of weight gain, and preventing moderate-severe bronchopulmonary dysplasia in VPIs.

OBJECTIVES@#To study the effect of sex on the clinical outcome of extremely preterm infants (EPIs)/extremely low birth weight infants (ELBWIs) by propensity score matching.@*METHODS@#A retrospective analysis was performed for the medical data of 731 EPIs or ELBWIs who were admitted from January 1, 2011 to December 31, 2020. These infants were divided into two groups: male and female. A propensity score matching analysis was performed at a ratio of 1:1. The matching variables included gestational age, birth weight, percentage of withdrawal from active treatment, percentage of small-for-gestational-age infant, percentage of use of pulmonary surfactant, percentage of 1-minute Apgar score ≤3, percentage of mechanical ventilation, duration of mechanical ventilation, percentage of antenatal use of inadequate glucocorticoids, and percentage of hypertensive disorders in pregnancy. The two groups were compared in the incidence rate of main complications during hospitalization and the rate of survival at discharge.@*RESULTS@#Before matching, compared with the female group, the male group had significantly higher incidence rates of neonatal respiratory distress syndrome, bronchopulmonary dysplasia (BPD), severe intraventricular hemorrhage, periventricular leukomalacia, necrotizing enterocolitis, and patent ductus arteriosus (P<0.05), while after matching, the male group only had a significantly higher incidence rate of BPD than the female group (P<0.05). There was no significant difference in the rate of survival at discharge between the two groups before and after matching (P>0.05).@*CONCLUSIONS@#Male EPIs/ELBWIs have a higher risk of BPD than female EPIs/ELBWIs, but male and female EPIs/ELBWIs tend to have similar outcomes.

RESUMEN
Circular RNAs (circRNAs),a kind of novel non-coding RNAs, have been shown to play animportant role in cellular redox reactions. In the previous study, we found that hsa_circ_0087354 wasclosely related to the cellular redox state by real-time PCR. After overexpression of hsa_circ_0087354, the relative expression of ROS1 were decreased significantly (P < 0. 01), while the levels of SOD1 wereincreased significantly (P < 0. 05) . The activities of SOD and Gpx as well as GSH concentration weresignificantly increased (P < 0. 01), and cell proliferation was promoted in cells (P < 0. 05) . Bioinformatics analysis predicted that there were binding sites between hsa-miR-199-3p and hsa_circ_0087354 as well as solute carrier family 7 member 11 (SLC7A11), which might have a targetedregulatory relationship. Dual luciferase reporter assay confirmed the targeted regulatory relationshipbetween hsa-miR-199-3p with hsa_circ_0087354, and SLC7A11. Overexpressed hsa_circ_0087354 plasmid and ctrl plasmid were constructed, hsa-miR-199a-3p, hsa-miR-199b-3p and hsa-miR-NC mimicswere synthesized. Real-time PCR analysis showed that the relative expression of hsa-miR-199-3p was observably decreased (P < 0.01), while the relative expression of SLC7A11 in cells was dramaticallyincreased after transfection of has_circ_0087354 plasmid (P < 0.05) . After transfection with hsa-miR-199-3p, the relative expressions of SLC7A11 were markedly decreased (P < 0.001) . The activities ofSOD and Gpx, GSH concentration (P<0.01), and cell proliferation rate (P < 0.05) were significantlyreduced. In conclusion, hsa_circ_0087354 could enhance the expression of SLC7A11, promote theproliferation of cells and reduce the oxidative stress by adsorption of hsa-miR-199-3p.
RESUMEN
BACKGROUND: G protein coupled receptor kinase 2 (GRK2) has been demonstrated to play a crucial role in the development of chronic pain. Acupuncture is an alternative therapy widely used for pain management. In this study, we investigated the role of spinal neuronal GRK2 in electroacupuncture (EA) analgesia. METHODS: The mice model of inflammatory pain was built by subcutaneous injection of Complete Freund's Adjuvant (CFA) into the plantar surface of the hind paws. The mechanical allodynia of mice was examined by von Frey test. The mice were subjected to EA treatment (BL60 and ST36 acupuncture points) for 1 week. Overexpression and down-regulation of spinal neuronal GRK2 were achieved by intraspinal injection of adeno associated virus (AAV) containing neuron-specific promoters, and microglial activation and neuroinflammation were evaluated by real-time PCR. RESULTS: Intraplantar injection with CFA in mice induced the decrease of GRK2 and microglial activation along with neuroinflammation in spinal cord. EA treatment increased the spinal GRK2, reduced neuroinflammation, and significantly decreased CFA-induced mechanical allodynia. The effects of EA were markedly weakened by non-cell-specific downregulation of spinal GRK2. Further, intraspinal injection of AAV containing neuron-specific promoters specifically downregulated neuronal GRK2, and weakened the regulatory effect of EA on CFA-induced mechanical allodynia and microglial activation. Meanwhile, overexpression of spinal neuronal GRK2 decreased mechanical allodynia. All these indicated that the neuronal GRK2 mediated microglial activation and neuroinflammation, and subsequently contributed to CFA-induced inflammatory pain. CONCLUSION: The restoration of the spinal GRK2 and subsequent suppression of microglial activation and neuroinflammation might be an important mechanism for EA analgesia. Our findings further suggested that the spinal GRK2, especially neuronal GRK2, might be the potential target for EA analgesia and pain management, and we provided a new experimental basis for the EA treatment of pain.

Abstract Objective: The purpose of this study was to explore the clinical effect of preoperative health education based on the WeChat platform for parents of children with simple congenital heart disease. Methods: In this study, participants were randomly divided into an intervention group (WeChat group, n=40) and a control group (leaflet group, n=40) in our center. All parents were required to complete the Family Caregiver Task Inventory (FCTI) on the first visit and the Zarit Burden Interview (ZBI) and FCTI before the operation. Clinical, family and relevant data from children and parents were collected and subsequently analyzed. Results: Before the operation, the FCTI score and the ZBI score in the WeChat group were significantly lower than those in the control group (P=0.010, P=0.027, respectively). Compared to the FCTI score on the first visit, the preoperative status score was significantly lower in the WeChat group (P=0.008). The rate of loss to follow-up and complications in the WeChat group was also significantly lower than in the control group (P=0.003). Conclusion: Preoperative health education assisted by the WeChat platform for parents of children with simple congenital heart disease can effectively improve the parents' care ability and reduce the burden of care, preoperative complications and the rate of loss to follow-up.

Abstract Objective: To investigate the effect of WeChat-based telehealth services on the postoperative follow-up of children who underwent congenital heart surgery during the COVID-19 epidemic. Methods: This study retrospectively analyzed the clinical and family data of 108 children who underwent congenital heart surgery and underwent remote follow-up via the WeChat platform from December 2019 to March 2020 in our hospital. Results: During the follow-up period, the WeChat platform was used to refer 8 children with respiratory infection symptoms to local hospitals for treatment. Two children with poor incision healing were healed after we used the WeChat platform to guide the parents in dressing the wounds on a regular basis at home. Nutritional guidance was given via the WeChat platform to 13 patients with poor growth and development. The psychological evaluation results of the parents showed that the median (range) SDS score was 43 (34-59), and 7 parents (6.5%) were classified as depressed; the median (range) SAS score was 41 (32-58), and 12 parents (11.1%) were classified as having mild anxiety. Conclusion: The use of WeChat-based telehealth services was effective for the remote postoperative follow-up of children who underwent congenital cardiac surgery during the COVID-19 epidemic. Providing WeChat-based telehealth services can reduce the amount of travel required for these children and their families, which is helpful for controlling and preventing the spread of COVID-19.
