OBJECTIVES: To investigate the risk factors for neonatal asphyxia in Hubei Enshi Tujia and Miao Autonomous Prefecture and establish a nomogram model for predicting the risk of neonatal asphyxia. METHODS: A retrospective study was conducted with 613 cases of neonatal asphyxia treated in 20 cooperative hospitals in Enshi Tujia and Miao Autonomous Prefecture from January to December 2019 as the asphyxia group, and 988 randomly selected non-asphyxia neonates born and admitted to the neonatology department of these hospitals during the same period as the control group. Univariate and multivariate analyses were used to identify risk factors for neonatal asphyxia. R software (4.2.2) was used to establish a nomogram model. Receiver operator characteristic curve, calibration curve, and decision curve analysis were used to assess the discrimination, calibration, and clinical usefulness of the model for predicting the risk of neonatal asphyxia, respectively. RESULTS: Multivariate logistic regression analysis showed that minority (Tujia), male sex, premature birth, congenital malformations, abnormal fetal position, intrauterine distress, maternal occupation as a farmer, education level below high school, fewer than 9 prenatal check-ups, threatened abortion, abnormal umbilical cord, abnormal amniotic fluid, placenta previa, abruptio placentae, emergency caesarean section, and assisted delivery were independent risk factors for neonatal asphyxia (P<0.05). The area under the curve of the model for predicting the risk of neonatal asphyxia based on these risk factors was 0.748 (95%CI: 0.723-0.772). The calibration curve indicated high accuracy of the model for predicting the risk of neonatal asphyxia. The decision curve analysis showed that the model could provide a higher net benefit for neonates at risk of asphyxia. CONCLUSIONS The risk factors for neonatal asphyxia in Hubei Enshi Tujia and Miao Autonomous Prefecture are multifactorial, and the nomogram model based on these factors has good value in predicting the risk of neonatal asphyxia, which can help clinicians identify neonates at high risk of asphyxia early, and reduce the incidence of neonatal asphyxia.

Patients with bicuspid aortic valve are often complicated with aortic dilatation. If the aortic valve is of good quality, aortic root replacement with aortic valve preservation is feasible. A 35-year-old male patient with bicuspid aortic regurgitation complicated with ascending aortic aneurysm underwent Remodeling+Ring (modified Yacoub) operation. Echocardiography showed that there was no aortic regurgitation on the 3rd day after operation, and the patient was discharged satisfactorily on the 6th day after operation. Remodeling+Ring surgery ensures the physiological movement of the aortic valve, solves the enlarged annulus, avoids the problems caused by valve replacement, and significantly improves the quality of life of patients, which is worth popularizing.

Recurrent genital herpes is a sexually transmitted disease induced by herpes simplex virus（HSV）， mainly manifested as erythema， papules， vesicles， erosion， and exudation on the skin and mucosal membranes of the genital and anal area， accompanied by burning pain， or tingling. Factors leading to its recurrence are overworking， fever， alcohol consumption， infection， sexual activity， etc. At least 1 in 10 of the 15-49-year-old population are infected with herpes simplex virus-2. There is currently no available method to completely remove the herpes simplex virus and prevent its recurrence， and recurrence seriously affects the quality of life and psychological health of patients. According to the theory of traditional Chinese medicine （TCM）， the recurrence of genital herpes is mostly related to wind， dampness， heat， yin deficiency of liver and kidney， internal injuries due to emotional disorder， and dietary preference. TCM has advantages in reducing its recurrence rate. The lower energizer is closely related to skin diseases， and "lower energizer resembles drainage". Thus， the lower energizer is closely related to water and damp metabolism. Recurrent genital herpes occurs in the lower energizer and belongs to lower energizer diseases， and the fluid metabolism and qi movement in lower energizer are closely related to the occurrence of the disease. Based on thought of "lower energizer resembling drainage" and the clinical characteristics of recurrent genital herpes， this paper considered malfunction of lower energizer as its pathogenesis. Thus， smoothing the lower energizer according to the prevailing circumstances is particularly important and the treatment principle should be dispersing the pathogen from lower energizer without damaging yin. Zhulingtang （Treatise on Cold Damage and Miscellaneous Diseases） cures the difficulty in urination and thirst with desire to drink by smoothing the lower energizer. Thus， Zhulingtang was selected to treat recurrent genital herpes. This study is expected to provide a new idea for its clinical diagnosis and treatment.

BACKGROUND: It has been a global trend that increasing complications related to pelvic floor surgeries have been reported over time. The current study aimed to outline the development of Chinese pelvic floor surgeries related to pelvic organ prolapse (POP) over the past 14 years and investigate the potential influence of enhanced monitoring conducted by the Chinese Association of Urogynecology since 2011. METHODS: A total of 44,594 women with POP who underwent pelvic floor surgeries between October 1, 2004 and September 30, 2018 were included from 22 tertiary academic medical centers. The data were reported voluntarily and obtained from a database. We compared the proportion of each procedure in the 7 years before and 7 years after September 30, 2011. The data were analyzed by performing Z test (one-sided). RESULTS: The number of different procedures during October 1, 2011-September 30, 2018 was more than twice that during October 1, 2004-September 30, 2011. Regarding pelvic floor surgeries related to POP, the rate of synthetic mesh procedures increased from 38.1% (5298/13,906) during October 1, 2004-September 30, 2011 to 46.0% (14,107/30,688) during October 1, 2011-September 30, 2018, whereas the rate of non-mesh procedures decreased from 61.9% (8608/13,906) to 54.0% (16,581/30,688) (Z = 15.53, P < 0.001). Regarding synthetic mesh surgeries related to POP, the rates of transvaginal placement of surgical mesh (TVM) procedures decreased from 94.1% (4983/5298) to 82.2% (11,603/14,107) (Z = 20.79, P < 0.001), but the rate of laparoscopic sacrocolpopexy (LSC) procedures increased from 5.9% (315/5298) to 17.8% (2504/14,107). CONCLUSIONS: The rate of synthetic mesh procedures increased while that of non-mesh procedures decreased significantly. The rate of TVM procedures decreased while the rate of LSC procedures increased significantly. TRIAL REGISTRATION NUMBER NCT03620565, https://register.clinicaltrials.gov.

Objective:To summarize the characteristics of hypertension and target organ damage in hospitalized children, so as to provide scientific basis for comprehensive prevention and management of hypertension children.Methods:The clinical data of 165 hospitalized children diagnosed with hypertension at Beijing Children′s Hospital from January 2017 to December 2019 were analyzed retrospectively.Data including medical history, clinical symptoms, signs, auxiliary examination and treatment strategy were collected and analyzed statistically.Results:Of 165 admitted hypertensive children who met the inclusion criteria, 35(21.2%)were classified as having primary hypertension, and 130(78.8%)were secondary hypertension.The body mass index(BMI)and the rate of family history of children with primary hypertension were higher than those of children with secondary hypertension, the differences were statistically significant( t=2.052, P=0.026; χ2=3.321, P=0.009). Among 165 children with hypertension, 137 had varying degrees of clinical symptoms(83.0%), only nine primary hypertension cases showed symptoms.The original etiologies of secondary hypertension included 78 cases of renal disease(60.0%), 23 cases of cardiogenic disease(17.7%), six cases of endocrine disease(4.6%)and five cases of rheumatic disease(3.8%). Of all admitted patients, the blood pressure of 158 cases(95.8%)decreased to normal with weight control, low-fat and low-salt diet, antihypertensive drugs and treatment of primary disease.Besides, the parents of seven cases gave up any treatment and left hospital. Conclusion:Secondary hypertension is the main type of hypertension in children, among which renal parenchymal disease is the most common etiology.The clinical symptoms also vary by its original etiology.The overall goal of this study is to reduce the risk of target organ damage, and get blood pressure under control relatively early and effectively.

Objective:To analyze the clinical characteristics of Kawasaki disease(KD)with complications of acute abdominal disease and to improve the diagnosis, treatment and prognosis of patients.Methods:A total of 2 931 cases with KD hospitalized from January 2016 to December 2019 in our department were retrospectively analyzed, including 14 children with acute abdominal disease(acute abdomen group). And 62 patients with KD but without acute abdominal disease were randomly selected as the control group.The clinical characteristics, laboratory examination and treatment between two groups were compared and analyzed.Results:There were 8 males and 6 females.The average age of patients was(4.46±0.74) years.Compared with control group, there was no significant difference in age, sex and proportion of coronary artery injury in acute abdomen group( P>0.05). Acute abdominal disease group were more likely to have gastrointestinal symptoms, intravenous immunoglobulin(IVIG) resistance and longer fever duration( P<0.05). C-reactive protein(CRP), alanine aminotransferase(ALT), aspartate aminotransferase(AST), γ-glutamyltranspeptidase(GGT) and total bilirubin(TBIL) in acute abdominal disease group were significantly higher( P<0.05). There was no significant difference in white blood cell, erythroayte sedimentation rate, hemoglobin, platelet, Na + , albumin between two groups( P>0.05). All of the 14 patients used IVIG, 3 of them were treated with hormone(methylprednisolone)and 1 patient accepted infliximab.All patients were discharged from hospital.After follow-up for 6 months to 3 years, all patients had no sequelae of digestive system. Conclusion:KD can be complicated with acute abdominal disease, some of which as the first symptom.Gastrointestinal manifestations such as abdominal pain are common.For children with obvious gastrointestinal symptoms, IVIG resistance, and long duration of fever, attention should be paid to the possibility of acute abdominal disease.For children with significantly elevated CRP, ALT, AST, GGT, and TBIL should to be alert to the possibility of acute abdominal disease.KD complicated with acute abdominal disease generally has good prognosis.It is important to treat KD in the first place.

Objective:To analyze the changes of myocardial damage markers during ventricular tachycardia (SVT) onset and efficacy of various therapeutic approaches.Methods:The clinical data of 256 children with SVT admitted to Beijing Children′s Hospital Affiliated to Capital Medical University from October 2018 to October 2019 were retrospectively analyzed.According to the age of onset, children were divided into groups of 0~3 years old, >3-6 years old, and >6 years old.According to the different heart rates at the time of attack, patients were divided into the groups of <180 times/min, 180~260 times /min, and >260 times /min.According to the treatment methods, children were divided into physical therapy group, drug therapy group and radiofrequency ablation group.Frequency of SVT attacks, heart rate at the onset, serum creatine kinase isoenzyme (CK-MB), troponin (cTn) I, and brain natiuretic peptide(BNP) were collected within 2 h after the onset stop.The recovery rate of each treatment group was counted.Results:Among the 256 cases, there were 135 males and 121 females, which aged from 1 month to 18 years, mean age was (10.2±2.2) years and SVT attacked from 1 to 8 times.The faster the heart rate during SVT attack, the higher CK-MB, cTnI and BNP ( P<0.05). The recovery rate was 27.6% in the mechanical stimulation group, 98.0% in the drug treatment group and 100% in the radiofrequency ablation group, respectively.Successful recovery rate was 47.2%(34 cases)with ATP, 71.7%(109 cases)with Propafenone, 67.3%(64 cases)with Cediland, 59.6%(31 cases)with Verapamil, 61.5%(24 cases)with Sotalol and 54.7%(29 cases)with Amiodarone.Eithty-two cases were successfully converted by two drugs(32.7%) and 38 cases were successfully converted by three drugs(15.1%). Conclusion:When SVT attacks, most children have myocardial damage.The faster the heart rate, the greater the damage in the heart muscle; The treatment of SVT in children should still be the first choice of physical therapy in older children, and if it is not effective, drug therapy should be selected.Radiofrequency ablation is the most effective method to cure tachyarrhythmia.

Objective:To study the effect of low-to-moderate dose glucocorticoid therapy on viral clearance in patients with COVID-19.Methods:A total of 72 patients diagnosed with COVID-19 from January 19 to February 17, 2020 at the First Affiliated Hospital, Zhejiang University School of Medicine were recruited. All patients received oral arbidol and combination of lopinavir/ritonavir or darunavir/cobistitat for antiviral therapy, and symptomatic supportive care. Among them, 51 patients received methylprednisolone (0.75-1.50 mg·kg -1·d -1) (glucocorticoid treatment group), and 21 patients did not use glucocorticoid (control group). The time of virologic negative conversion in sputum and the time of radiologic recovery in lung since onset were compared between the two groups. The Kruskal-Wallis test or Fisher exact test was used to compare the difference between groups. Results:The median ages of the glucocorticoid group and the control group were 52 (45, 62) and 46 (32, 56) years ( χ2=4.365, P<0.05). The clinical conditions at hospital admission were different between the two groups ( P<0.01). The severe cases accounted for 52.0%, while moderate cases in the control group accounted for 71.4%. The median times from the onset to virologic negative conversion in the two groups were 15 (13, 20) and 14 (12, 20) days ( P>0.05). The median times from onset to radiologic recovery were 13 (11, 15) and 13 (12, 17) days in the two groups ( P>0.05). In moderate cases, the median times from the onset to virologic conversion in sputum were 13 (11, 18) days in the glucocorticoid group and 13 (12, 15) days in the control group ( P>0.05). The median times from onset to radiologic recovery in lung were 12 (10, 15) and 13 (12, 17) days, respectively ( P>0.05). Conclusions:Low-to-moderate glucocorticoid treatment has no effect on the time of virus clearance in patients with different clinical types of COVID-19, and also no effect on accelerating radiologic recovery in lung, so it is not recommended.
