Objective: To explore the characteristics of plasma Epstein-Barr virus (EBV) DNA in primary infection in pediatric cases. Methods: The laboratory and clinical data of 571 children diagnosed with EBV primary infection in Children's Hospital of Fudan University during September 1^st, 2017 to September 30^th, 2018 were retrospectively analyzed. According to the results of plasma EBV DNA, they were divided into positive group and negative group. According to the EBV DNA, they were devided into high plasma virol load group and low plasma virol load group. The Chi-square test, Wilcoxon rank sum test were used to compare the differences between groups. Results: Among the 571 children with EBV primary infection, 334 were males and 237 were females. The age of first diagnosis was 3.8 (2.2, 5.7) years. There were 255 cases in positive group and 316 cases in negative group. The percentage of cases with fever,hepatomegaly and (or) splenomegaly, elevated transaminase in the positive group were higher than those in the negative group (235 cases (92.2%) vs. 255 cases (80.7%), χ²=15.22, P<0.001; 169 cases (66.3%) vs. 85 cases (26.9%), χ²=96.80, P<0.001; and 144 cases (56.5%) vs. 120 cases (38.0%), χ²=18.27, P<0.001; respectively).In the positive group, 70 cases were followed up for 46 (27, 106) days, 68 cases (97.1%) turned negative within 28 days, with the exception of 2 cases (2.9%) developed chronic active EBV infection by follow-up revision.There were 218 cases in high plasma viral DNA copies group and 37 cases in low copies group. More cases presented with elevated transaminases in the high plasma viral DNA copies group than those in the low group (75.7% (28/37) vs. 56.0%(116/207), χ²=5.00, P=0.025).Both the positive rate of EBV DNA in peripheral blood leukocytes (84.2% (266/316) vs. 44.7% (255/571), χ²=76.26, P<0.001) and the copies of EBV DNA (7.0×10⁷ (1.3×10⁷, 3.0×10⁸) vs. 3.1×10⁶ (1.6×10⁶, 6.1×10⁶) copies /L, Z=15.23, P<0.001) were higher than that of plasma. Conclusions: In immunocompetent pediatric cases diagnosed as EBV primary infection, cases with positive plasma EBV DNA were prone to have fever, hepatomegaly and (or) splenomegaly, and elevated transaminase than those with negative plasma viral DNA. The plasma EBV DNA usually turns negative within 28 days after initial diagnosis.Most cases with high viral load in plasma showed elevated aminotransferase.

Objective: To observe the clinical efficacy of auricular point pricking-bloodletting plus auricular point sticking therapy for acne vulgaris. Methods: A total of 66 patients with acne vulgaris were randomized into an observation group and a control group by the random number table, with 33 cases in each group. The observation group was treated with auricular point pricking-bloodletting plus auricular point sticking therapy, and the control group was treated only with auricular point sticking therapy. The treatments of both groups were performed twice a week, 4 weeks as a course of treatment, for 3 courses in total. The scores of skin lesions and dermatology life quality index (DLQI) scores were recorded before and after treatment to assess the clinical efficacy. Results: During the trial, there were 3 cases of drop-out both in the observation group and the control group. After 3 courses of treatment, the total effective rate of the observation group was 96.7％, while that of the control group was 76.7％. The difference between the two groups was statistically significant (P<0.05). The intra-group comparison showed that the scores of skin lesion and DLQI were both decreased with the increase of treatment times, that was, the scores were lower than those at the previous time point (allP<0.05). After 1, 2, and 3 courses of treatment, the scores of skin lesion and DLQI of both groups were statistically different from those of the same group before treatment (allP<0.05). At every time point during the treatment, the scores of skin lesion and DLQI of the observation group were lower than those of the control group, and the differences between the two groups were statistically significant (all P<0.05). Conclusion: Auricular point pricking-bloodletting plus auricular point sticking has a better curative effect than auricular point sticking therapy alone in the treatment of acne vulgaris, and has a time-effect correlation.

Background: Gestational diabetes mellitus (GDM) is a common complication during pregnancy. Obesity and overweight are closely related to metabolic diseases and diabetes. However, the role of adipose tissue in the pathogenesis of GDM remains to be studied. The aim of this study was to investigate the correlation of vitamin D (VD) levels, VD receptor (VDR), and peroxisome proliferatoractivated receptor γ (PPARγ) expression with GDM in overweight or obese women. Methods: One hundred and forty pregnant women with full-term single-birth cesarean-section were selected as the study subjects and grouped (70 GDM women, including 35 non-overweight/non-obese women [group G1] and 35 women with overweight or obesity [group G2]; 70 pregnant women with normal glucose tolerance, including 35 non-overweight/non-obese women [group N1] and 35 overweight/obese women [group N2]). The levels of serum VD, blood biochemistry, and adiponectin were compared in these women. Subcutaneous adipose tissue was isolated from the abdominal wall incision. VDR and PPARγ messenger RNA (mRNA) transcript levels in these adipose tissues were quantified by real-time polymerase chain reaction. The differences between the levels of PPARγ protein and phosphorylated PPARγ Ser273 were detected by Western blotting. Results: The serum VD level of GDM women was lower in comparison to that of women with normal glucose tolerance (G1 vs. N1: 20.62 ± 7.87 ng/mL vs. 25.85 ± 7.29 ng/mL, G2 vs. N2: 17.06 ± 6.74 ng/mL vs. 21.62 ± 7.18 ng/mL, P < 0.05), and the lowest in overweight/obese GDM women. VDR and PPARγ mRNA expression was higher in the adipose tissues of GDM women in comparison to that of women with normal glucose tolerance (VDR mRNA: G1 vs. N1: 210.00 [90.58-311.46] vs. 89.34 [63.74-159.92], G2 vs. N2: 298.67 [170.84-451.25] vs. 198.28 [119.46-261.23], PPARγ mRNA: G1 vs. N1: 100.72 [88.61-123.87] vs. 87.52 [66.37-100.04], G2 vs. N2: 117.33 [100.08-149.00] vs. 89.90 [76.95-109.09], P < 0.05), and their expression was the highest in GDM+ overweight/obese women. VDR mRNA levels positively correlated with the pre-pregnancy body mass index (BMI), pre-delivery BMI, fasting blood glucose (FBG), homeostasis model assessment of insulin resistance (HOMA-IR), and PPARγ mRNA while it negatively correlated with the VD and the adiponectin levels (r = 0.395, 0.336, 0.240, 0.190, 0.235, -0.350, -0.294, respectively, P < 0.05). The degree of PPARγ Ser273 phosphorylation increased in obese and GDM pregnant women. PPARγ mRNA levels positively correlated with pre-pregnancy BMI, pre-delivery BMI, FBG, HOMA-IR, serum total cholesterol, triglyceride, free fatty acid, and VDR mRNA, while it negatively correlated with the VD and adiponectin levels (r = 0.276, 0.199, 0.210, 0.230, 0.182, 0.214, 0.270, 0.235, -0.232, -0.199, respectively, P < 0.05). Conclusions Both GDM and overweight/obese women had decreased serum VD levels and up-regulated VDR and PPARγ mRNA expression in adipose tissue, which was further higher in the overweight or obese women with GDM. VD may regulate the formation and differentiation of adipocytes through the VDR and PPARγ pathways and participate in the occurrence of GDM.

Objective To investigate the differences in the expression of vitamin D receptor (VDR) and serum vitamin D levels in subcutaneous adipose tissue between overweight/obese and normal-weight gravidas, and the relationship between these two indicators and gestational diabetes mellitus (GDM). Methods Women with full-term singleton pregnancies who underwent elective cesarean section in Changzhou Maternal and Child Health Care Hospital Affiliated to Nanjing Medical University from January 2015 to April 2017 were enrolled. Among them, there were 70 cases GDM women, including 35 normal-weight (NW-GDM group) and 35 overweight/obese women (OW-GDM group). During the same period, another 70 pregnant women with normal glucose tolerance who underwent scheduled cesarean delivery were selected as the control group, including 35 normal weight women (NW-control group) and 35 obese/overweight women (OW-control group). Fasting blood samples were collected before operation to determine the levels of different biomarkers, including vitamin D, lipid, fasting blood glucose, fasting insulin and adiponectin, and to calculate the homeostasis model assessment-insulin resistance (HOMA-IR). Two subcutaneous adipose tissue samples of the abdominal wall were taken during the operation to detect the expression and distribution of VDR protein with immunohistochemistry. Meanwhile, VDR mRNA transcription level was quantitatively analyzed using real-time fluorescence quantitative polymerase chain reaction. One-way analysis of variance, LSD, Kruskal-Wallis test, Mann-Whitney U test, Chi-square test and logistic regression analysis were used for statistical analysis. ResuLts (1) The body mass index (BMI) of the OW-control group and the OW-GDM group before pregnancy and delivery were all higher than that of the NW-control group and the NW-GDM group [BMI before pregnancy: (29.2±2.9), (29.4±3.8) vs (21.1±2.3) and (21.9±2.0) kg/m2, F=87.766; BMI before delivery: (35.2±3.4), (35.1±4.3) vs (27.9±2.8) and (28.8± 3.3) kg/m2, F=44.827; all P<0.001]. Newborn birth weight and the proportion of diabetic family history in the OW-GDM group were higher comparing to the NW- and OW- control group [(3 893±498) vs (3 501±402) and (3 625±332) g, F=4.751; 22.9%(8/35) vs 5.7%(2/35) and 5.7%(2/35), χ2=7.869; all P<0.05]. (2) In the OW-control group, the fasting insulin level and HOMA-IR were higher and the adiponectin and vitamin D concentration were lower than those in the NW-control group [13.3(12.3-14.5) vs 12.0(10.4-13.3) mmol/L, 2.7(2.4-3.0) vs 2.2(2.0-2.7), (61.8±20.4) vs (74.9±29.3) ng/ml, (21.6±7.2) vs (25.9±7.3) ng/ml; all P<0.05], and similar results were found between the OW-GDM group and the NW-GDM group [15.3(12.3-19.5) vs 12.0(10.1-15.8) mmol/L, 3.4(2.6-4.1) vs 2.6(2.1-3.2), (50.3±22.3) vs (62.1±23.2) ng/ml, (17.1±6.7) vs (20.6±7.9) ng/ml, all P<0.05]. Compared with the NW-control group, the NW-GDM group had higher fasting glucose and lower high density lipoprotein-cholesterol (HDL-C), adiponectin and vitamin D levels [4.6(4.3-5.1) vs 4.3(4.0-4.5) mmol/L, 1.7(1.6-1.9) vs 2.1(1.6~2.4) mmol/L, (62.1±23.2) vs (74.9±29.3) ng/ml, (20.6±7.9) vs (25.9±7.3) ng/ml; all P<0.05]. Compared with the OW-control group, fasting glucose, fasting insulin and HOMA-IR were higher and HDL-C, adiponectin and vitamin D levels were lower in the OW-GDM group [4.7(4.4-5.4) vs 4.5(4.2-4.7) mmol/L, 15.3(12.3-19.5) vs 13.3(12.3-14.5) mmol/L, 3.4(2.6-4.1) vs 2.7(2.4-3.0), 1.6(1.4-1.8) vs 1.9(1.7-2.2) mmol/L, (50.3±22.3) vs (61.8±20.4) ng/ml, (17.1±6.7) vs (21.6±7.2) ng/ml; all P<0.05]. (3)The overall vitamin D deficiency rate during the third trimester of the four groups was 78.6% (110/140), and the figure was 62.8% (22/35), 82.8% (29/35), 77.1% (27/35) and 91.4% (32/35) in the NW-control group, OW-control group, NW-GDM group and OW-GDM group (χ2=8.994, P=0.029), indicating a higher rate in the OW-GDM group than that in the NW-control group (χ2=8.102, P=0.004). (4) VDR was expressed in the nucleus of adipose tissue in all samples and statistic difference in protein expression was found among the four groups. VDR mRNA expression was higher in both GDM subgroups than that in the two control subgroups, and also higher in the two overweight/obese subgroups than in the corresponding normal-weight subgroups. (5)Serum vitamin D level was negatively correlated with fasting blood glucose and pre-pregnancy BMI, and positively correlated with adiponectin (P<0.05). The incidence of GDM was related to family history of diabetes, VDR mRNA, total cholesterol, HDL-C and HOMA-IR. ConcLusions GDM and overweight/obese patients had decreased serum vitamin D level and increased VDR in subcutaneous adipose tissue. These two factors are closely related to GDM.

The 70% ethanol extract of the whole plant of Souliea vaginata was purified by multi-chromatographic methods including macroporous resin,silica gel,Sephadex LH-20,and C18-reversed-phase column chromatography.

Objective To compare the safety and effectiveness of Propofol-Fentanyl and Propofol-Remifentanil total intravenous anesthesia for airway foreign body (FB) removal in children. Method 280 children aged 1 ~ 3 years underwent rigid bronchoscopy for FB removal were randomized into two groups. The Fentanyl group (Group F, n = 140) were given Propofol 2.00~3.00 mg/kg and Fentanyl 2.00 μg/kg for induction and Propofol 200.00 ~ 500.00 μg/(kg·min) for maintenance of anesthesia. The Remifentanil group (Group R, n = 140) were given Propofol 2.00 ~ 3.00 mg/kg and Remifentanil 1.00 ~ 1.50 μg/kg for induction of anesthesia, while anesthesia was maintained with Propofol 200.00 ~ 500.00 μg/(kg·min) and Remifentanil 0.10 ~ 0.20 μg/(kg·min). All the children during the procedure were with spontaneous respiration. SpO2 before inserting rigid bronchoscope (T1), 1 min (T2) and 3 min (T3) after insertion, 3 min (T4) and 10 min (T5) after extraction were recorded. PETCO2 after endoscopy (T6) was measured. Adverse events, including body movement, cough, breath-holding, and hypoxemia,were observed. The time of induction, surgery, recovery and the total dosage of the intravenous agents were recorded. Results SpO2 of the two groups were in normal range at T1 ~ 5, which was higher in group R than group F at T2 ~ 5 (P < 0.05). PETCO2 of group R was lower than group F at T6 (P < 0.05). The rate of body movement and cough were comparable between the two groups (P > 0.05), while breath-holding and hypoxemia were more frequent in group F (P < 0.05). The time of induction and recovery were shorter in group R (P < 0.05), while surgery time and the Propofol dosage were similar (P > 0.05). The total dose of Fentanyl was significantly higher than Remifentanil (P < 0.05). Conclusion Combination of Propofol with Fentanyl or Remifentanil both produce effective anesthesia in children undergoing FB removal. But Propofol-Remifentanil provides more stable oxygen saturation, faster induction and recurrence of anesthesia, as well as less intraoperative complications.
