Objective To investigate the infection of Xuebijing injection on inflammatory factor of large sized avulsion patients.Methods 70 patients being selected with large sized avulsion were randomly recruited into a treatment group(35 patients)and a control group(35 patients).The control group received traditional comprehensive treatment.On this basis,Xucbijing injection was injected to the treatment group on admission day,and Xuebijing injection 50 ml in 0.9%NaCl solution 100 ml was,intravenously infused for 60 min once,2 times daily,up to 7 d.TNF-α,IL-6,CRP,WBC and NEU%of the two groups were respectively detected before treatment and 7 days after the treatment.Exudation of wound surface was also observed.Results After 7 days of treatment,there was significant difierence in the treatment group compared with pretreatment(P＜0.01).There was statistical difference between two groups after 7 days of treatment(P＜0.01).Exudation of wound surface of the treatment group was less than the control group's.Conclusion Xuebijing injection has antagonistic effect on inflammatory factor of large sized avulsion patients and can lessen exudation of wound surface.

OBJECTIVE: To investigate the predictive value of cervical length（CL）changes in spontaneous preterm birth（SPTB）in twin pregnancies in the second and third trimesters of pregnancy.METHODS: A retrospective analysis was made of 166 cases of twin pregnant women who underwent transvaginal ultrasound to measure CL during the second trimester of pregnancy（20~25 weeks）and the third trimester of pregnancy（28~32 weeks）from January 2014 to December 2017 in the Third Hospital of Peking University and Tongzhou Maternal and Child Health Hospital of Beijing.Evaluate the predictive value of CL changes in SPTB before 32 and 34 weeks.The area under the receiver-operating characteristics（ROC）curve was compared by bootstrap method.Assessment of the value of CL in the third trimester of pregnancy and CL in the second trimester of pregnancy alone in predicting SPTB before 32 and 34 weeks.RESULTS: Of the 166 cases,90 were full-term delivery and 76 were premature delivery.The median CL of mid and late pregnancy was 34 mm and 29 mm respectively,and it was 35.5 mm and 31 mm,and in full-term delivery.32.5 mm and21 mm in premature delivery,respectively.There were significant differences among the three groups（All P<0.001）.According to whether the shortening of CL was more than 20%,they are divided into shortening group（CL shortening more than 20%,78 cases）and stabilizing group（no shortening of CL or shortening less than 20%,88 cases）.The preterm birth rate of shortening group was 2.22 times and 1.85 times higher than that of stabilizing group before 32 weeks and 34 weeks,but there was no significant difference.Of 40 cases with CL≤ 25 mm,there were 34 cases in shortening group,6 cases in stabilizing group.Excluding these twin pregnant women,the preterm birth rate in the shortening group increased by 7.58 times and 2.09 times than that in the stabilizing group before 32 weeks and 34 weeks.There was a significant difference in the preterm birth rate between the shortening group and the stabilizing group before 32 weeks（P=0.049）.The area under ROC curve of preterm birth predicted by CL in late pregnancy was increased compared with that in mid-pregnancy before 32 weeks and 34 weeks,but the difference was not statistically significant.CONCLUSION: In twin pregnancies,the CL shortening ≥ 20% at 28~32 weeks of gestation increases the risk of preterm birth before 32 weeks;with CL>25 mm and CL shortening≥ 20%,it can better predict preterm birth before 32 weeks.

OBJECTIVE: To test the reliability and validity of the Chinese version of adverse childhood experiences international questionnaire (ACE-IQ) in Chinese parents of preschool children. METHODS: The parents of preschool children in 6 kindergartens in Tongzhou District of Beijing were selected by stratified random cluster sampling, and the Chinese version of ACE-IQ after translation and adaptation was used for survey online. The collected data were randomly divided into two parts. One part of the data (n=602) was used for exploratory factor analysis (EFA), to screen items and evaluate structural validity, and then form the final Chinese version of ACE-IQ. The other part of the data (n=700) was used for confirmatory factor analysis (CFA), criterion validity analysis and reliability analysis. At the same time, experts investigation method was used to evaluate the content validity of the final Chinese version of ACE-IQ. RESULTS: After deleting four items of collective violence, the Chinese version of ACE-IQ with twenty-five items indicated good structural, criterion and content validity. Analysis results showed that the Chinese version of ACE-IQ presented a seven-factor model dimension, namely emotional neglect, physical neglect, family dysfunction, family violence, emotional and physical abuse, sexual abuse and violence outside the home, and the total score of the binary version of ACE-IQ Chinese version was positively correlated with the total score of childhood trauma questionaire-28 item short form (CTQ-SF, r=0.354, P < 0.001) and the center for epidemiological studies depression scale (CES-D, r=0.313, P < 0.001) respectively. Results from five experts showed that the item-level content validity index (I-CVI) of 25 items was between 0.80 and 1.00, and the average of all I-CVIs on the scale (S-CVI/Ave) of the scale was 0.984. At the same time, the internal consistency (Cronbach's α coefficient) of the whole scale was 0.818, and the split-half reliability (Spearman-Brown coefficient) was 0.621, which demonstrated good reliability. CONCLUSION This study has formed a Chinese version of ACE-IQ with 25 items and 7 dimensions, which has good reliability and validity among the parents of preschool children in China. It can be used as an evaluation instrument for measuring the minimum threshold of the adverse childhood experiences in the parents of preschool children in the cultural background of China.

OBJECTIVE: To explore the association of maternal periconceptional folic acid or multiple micronutrients supplementation during periconceptional period and the serum vitamin E (Vit.E) concentration in the 1st trimester of gestational period. METHODS: A retrospective cohort study was conducted based on the prenatal health care system and clinical laboratory information system. Totally, 22 171 pregnant women who had their prenatal health care and gave birth in Tongzhou Maternal & Child Health Hospital of Beijing from Jan. 2016 to Dec. 2018 were recruited. The usage patterns of nutritional supplements [folic acid (FA) or multiple micronutrients (MM)] during periconceptional period were independent variables, and serum Vit.E concentration and serum Vit.E concentration≥11.2 mg/L in the 1st trimester of gestational period were outcome variables for generalized linear regression model and Logistic regression model, respectively, to analyze the relationships between the independent and outcome variables. RESULTS: The range of the serum Vit.E concentration in the 1st trimester of gestational period was 5.2-24.0 mg/L, and the median concentration was 10.1 (8.8-11.6) mg/L; the excess rate of the serum Vit.E of those who took MM supplementation was 0.3%, and the rates for the groups of FA only or no nutritional supplements used were both 0.1%. Compared with women without nutritional supplement or the women taking FA, the women who took MM had higher serum Vit.E levels in the 1st trimester of gestational period (both P < 0.05). The women taking FA or MM initiated before the conception showed that the serum Vit.E concentration in the 1st trimester of gestational period was higher than that after the conception (P < 0.05), and the serum Vit.E concentration of women who took regularly was higher than that of irregular taking (P < 0.05); with taking compliance elevated, the serum Vit.E concentration of the two groups of women taking FA or MM increased (P < 0.05). The risk of serum Vit.E concentration≥11.2 mg/L among the women taking MM was higher than that of the women without nutritional supplements or taking FA only [odds ratio (OR)=1.36, 95% confidence interval (95%CI): 1.21-1.53; OR=1.39, 95%CI: 1.31-1.48)]; women who took FA or MM showed a lower risk for serum Vit.E concentration≥11.2 mg/L of taking it after the conception than before, the ORs (95%CI) were 0.86 (95%CI: 0.77-0.96) and 0.88 (95%CI: 0.81-0.95), respectively; the women taking the two supplements regularly had higher risk for serum Vit.E concentration≥11.2 mg/L than irregular taking, the ORs (95%CI) were 1.16 (95%CI: 1.05-1.29) and 1.13 (95%CI: 1.04-1.22) for FA and MM users, respectively; with the compliance increasing, the women taking MM had a higher risk of serum Vit.E levels≥11.2 mg/L in the 1st trimester [OR (95%CI) was 1.10 (1.07-1.14)], but for FA users, the OR (95%CI) was 1.04(1.00-1.08). CONCLUSION Vit.E nutritional status in women in early gestational period in Beijing was generally good, and the excess rate of serum Vit.E was higher in women who took MM during periconceptional period than those without nutritional supplement or taking FA only, suggesting that women need to consider their own Vit.E nutritional status to choose the type of nutritional supplements during periconceptional period, so as to avoid related health hazards.

OBJECTIVE: To investigate the incidence of hypertension disorders complicating pregnancy (HDCP) and vitamin E (VE) nutritional status among pregnant women in Beijing, and to determine the relationship between serum VE concentration in the first trimester of pregnancy and the risk of developing HDCP. METHODS: A retrospective cohort study was performed including 22 283 cases of pregnant women who underwent singleton deliveries in Tongzhou Maternal & Child Health Hospital of Beijing from January 2016 through December 2018 and received tests of serum VE concentrations in the first trimester of pregnancy. Nonconditional Logistic regression model was used to analyze the association between serum VE concentration levels and the risk of developing HDCP. RESULTS: The total incidence of HDCP was 5.4%, with the incidence of gestational hypertension around 2.1% and the incidence of preeclampsia-eclampsia around 3.3%. The median concentration of serum VE in early pregnancy was 10.1 (8.8-11.6) mg/L, and 99.7% of the participants had normal serum VE concentrations. The incidence of gestational hypertension and that of preeclampsia-eclampsia had been annually increasing in three years; a linear-by-linear association had also been observed between the serum VE concentrations and the years of delivery. According to the results of the univariable and the multivariable Logistic regression analyses, higher risks of developing HDCP had been observed among women with higher serum VE concentrations. Compared to those with serum VE concentrations in interquartile range (P₂₅-P₇₅) of all the participants, the women whose serum VE concentrations above P₇₅ were at higher risks to be attacked by HDCP (OR = 1.34, P < 0.001), gestational hypertension (OR = 1.39, P = 0.002), or preeclampsia-eclampsia (OR = 1.34, P = 0.001), as suggested by the results of the multivariable Logistic regression model analyses. In addition, the women with serum VE concentrations of 11.2 mg/L or above had a significantly higher risk of developing HDCP than those whose serum VE concentrations of P₄₀-P₆₀ of all the participants, and this risk grew higher as serum VE concentrations in the first trimester of pregnancy increased. CONCLUSION Women in Beijing are at good nutritional status. From January 2016 to December 2018, the incidence of HDCP increased with serum VE concentration level, and serum VE concentration of 11.2 mg/L is an indicator of an increased risk of developing HDCP, suggesting that pregnant women should take nutritional supplements containing VE carefully.

OBJECTIVETo investigate the efficacy and safety of the Chinese herbal therapeutic regimen of activating blood circulation (TRABC) in treatment of hypertensive intracerebral hemorrhage (HICH).

METHODSThis was a multi-center prospective randomized open-label blinded-endpoint (PROBE) trial with HICH admitted to 12 hospitals. Totally 240 participants were randomized to the treatment group treated with TRABC in addition to conventional Western treatment or the control group with conventional Western treatment equally for 3 months. Primary outcome was degree of disability as measured by modified Rankin Scale (mRS). Secondary outcomes were the absorption of hematoma and edema, National Institutes of Health Stroke Scale (NIHSS) scores and patient-reported outcome measures for stroke and Barthel activities of daily living index. Adverse events and mortality were also recorded.

RESULTSAfter 3 months of treatment, the rate of mRS 0-1 and mRS 0-2 in the treatment group was 72.5% and 80.4%, respectively, and in the control group 48.1% and 63.9%, respectively, with a significant difference between groups (P<0.01). Hematoma volume decreased significantly at day 7 of treatment in the treatment group than the control group (P=0.038). Average Barthel scores in the treatment group after treatment was 89.11±19.93, and in the control group 82.18±24.02 (P=0.003). NIHSS scores of the two groups after treatment decreased significantly compared with before treatment (P=0.001). Patient-reported outcomes in the treatment group were lower than the control group at day 21 and 3 months of treatment (P<0.05). There were 4 deaths, 2 in each group, and 11 adverse events, 6 in the treatment group and 5 in the control group.

CONCLUSIONThe integrative therapy combined TRABC with conventional Western treatment for HICH could promote hematoma absorption thus minimize neurologic impairment, without increasing intracerebral hematoma expansion and re-bleeding.

BACKGROUNDThe aim of this study was to evaluate the efficacy of ultrasonic features in predicting the malignancy of thyroid nodules in a group of Chinese patients.

METHODSIn all, 762 patients with thyroid nodules (424 malignant and 338 benign) underwent ultrasound (US) check and surgery between March 2011 and July 2014 at Peking University First Hospital were identified. Univariate and receiver operating characteristic (ROC) analyses were performed to calculate the sensitivity, specificity, negative and positive predictive values of each US feature, and the accuracy of their combinations for prediction of malignancy.

RESULTSPatients with malignant nodules were younger and without obvious risk history than those in the benign group (P < 0.001, P = 0.93). No individual US sign was fully predictive of a malignant lesion. The Youden indexes of irregular margins and hypoechogenicity were the first and second highest in all US features, which were 51.9% and 45.2%, respectively. The sensitivity of solid components (89.7%) and hypoechogenicity (89.2%) and the specificity of taller-than-wide shape (98.5%) and microcalcifications (90.6%) were the first and second highest in all US features. Intranodular flow on a color Doppler examination was a weak predictor of malignancy. Under ROC analysis excepting intranodular flow, the 95% confidence interval (CI) of areas under the curves of hypoechogenicity and irregular margins with any one of the US features were overlapped that of five-feature combinations (95% CI: 0.850-0.901).

CONCLUSIONSWe should be alert with taller-than-wide shape and microcalcifications. Intranodular flow was a weak predictor of malignancy. According to Youden indexes and ROC analysis, irregular margins and hypoechogenicity combined with solid component or taller-than-wide shapes or microcalcifications have a high predicative value for malignant thyroid nodules in Chinese patients.
