Objective:To analyze the correlation of glycosylated hemoglobin (HbA 1c) level in the late pregnancy gestational diabetes mellitus (GDM) patients and fetal weights, neonatal Apgar scores, maternal and infant adverse outcomes. Methods:One hundred and eighty-seven pregnant women who were diagnosed with GDM from January 2015 to July 2019 and delivered in Yixing People′s Hospital after standard diagnosis and treatment were divided into four groups (A group: HbA 1c<6.0%, 65 cases; B group: HbA 1c: 6.0% - 6.5%, 49 cases; C group: HbA 1c 6.6%-7.0%, 39 cases; D group: HbA 1c>7.0%, 34 cases) according to the HbA 1c examination results at 28 to 32 weeks of gestation. General data, fetal weights, neonatal Apgar scores and maternal and infant adverse outcomes were compared among the four groups. The correlation between GDM HbA 1c and fetal weights, neonatal Apgar scores and maternal and infant adverse outcomes were analyzed by unconditional Logistic regression. Results:In general data of GDM pregnant women with different HbA 1c levels, only oral glucose tolerance test (OGTT) fasting blood glucose: (4.68 ± 0.60), (4.89 ± 0.69), (5.23 ± 0.90), (6.48 ± 2.17) mmol/L; postprandial 1 h blood glucose: (9.84 ± 1.56), (10.09 ± 1.84), (10.6 ± 2.01), (12.74 ± 4.12) mmol/L; postprandial 2 h blood glucose: (8.65 ± 1.49), (8.86 ± 1.76), (9.28 ± 2.15), (11.56 ± 4.93) mmol/L, showed statistically significant differences ( P<0.05). Among the newborns of GDM pregnant women with different HbA 1c levels, there were statistically significant differences in the macrosomic infant rates: 1.54%(1/65), 10.20%(5/49), 12.82%(5/39), 17.65%(6/34); rates of neonatal Apgar scores<7 points:13.85%(9/65), 16.33%(8/49), 25.64%(10/39), 44.12%(15/34); the proportion of maternal and infant adverse outcomes: 24.62%(16/65), 24.49%(12/49), 28.21%(11/39), 50.00%(17/34), showed statistically significant differences ( P<0.05). After adjusting OGTT by unconditional Logistic regression analysis, HbA 1c (6.6%-7.0% and>7.0%) was independent risk factor for macrosomic infants: OR = 1.430, 95% CI = 1.035-1.977, P = 0.030; OR = 2.042, 95% CI = 1.311-3.180, P = 0.001; maternal and infant adverse outcomes: OR = 1.774, 95% CI = 1.130-2.874, P = 0.010; OR = 3.387, 95% CI = 1.608-7.133, P = 0.001. HbA 1c>7.0% was independent risk factors for neonatal Apgar scores<7 points: OR = 1.848 95% CI = 1.086-3.143, P = 0.023. Conclusions:There was a significant correlation between HbA 1c in GDM pregnant women in the late pregnancy and macrosomic infants, neonatal Apgar scores, and maternal and infant adverse outcomes. In particular, GDM pregnant women with HbA 1c>7.0% should be alert to the risk of macrosomic infants, neonatal Apgar score<7 points, and maternal and infant adverse outcomes.

Objective:To study and explore the effect and mechanism of action of Jieduhuayu granules on oxidative injury of human liver L02 cells.Methods:Human liver L02 oxidative injury model was established with 0.1 mmol/ L H 2O 2 intervention for 1 h, and treated with different concentrations of Jieduhuayu (JDHY) solution. Hepatocytes were divided into five groups: normal, H 2O 2, H 2O 2 + JDHY (0.5 mg/ml), H 2O 2 + JDHY (1 mg/ml), and H 2O 2 + JDHY (1.5 mg/ml). MTT assay was used to detect hepatocytes activity. Transmission electron microscope was used to observe mitochondrial morphology in hepatocytes. Biochemical test was used to detect the levels of superoxide dismutase, lactate dehydrogenase, alanine aminotransferase, aspartate aminotransferase, malondialdehyde, and reduced glutathione and albumin in hepatocytes. Western blot was used to detect the expression levels of rabbit anti-phosphatidylinositol 3-kinase (PI3K), AKT and mTOR in hepatocytes. One-way analysis of variance was used for comparison between multiple groups, and the LSD method was used for pairwise comparison. Results:Compared with the normal group, the cell proliferation activity ( P < 0.05), mitochondrial vacuolization, superoxide dismutase activity, reduced albumin and glutathione content, and PI3K, AKT, and mTOR protein expression levels in the H 2O 2 group were all significantly reduced ( P < 0.05), while the content of malondialdehyde and the activities of alanine aminotransferase, aspartate aminotransferase and lactate dehydrogenase were significantly increased ( P < 0.05). Compared with H 2O 2 group, the cell proliferation activity ( P < 0.05), alterations in morphological remission of mitochondria, superoxide dismutase activity, reduced albumin and glutathione content, and PI3K, AKT and mTOR protein expression levels in the H 2O 2 + JDHY (1 mg/ml) and H 2O 2 + JDHY (1.5 mg/ml) group ( P < 0.05) were all significantly increased ( P < 0.05), while malondialdehyde content and alanine aminotransferase, aspartate aminotransferase and lactate dehydrogenase activities were significantly decreased ( P < 0.05). Conclusion:Jieduhuayu granule can effectively improve oxidative stress and mitochondrial injury in hepatocytes, and its effect may be related to the promoting expression of PI3K/AKT/mTOR signaling pathways.

OBJECTIVETo investigate the feasibility of no nasogastric intubation and early oral feeding at will after thoracolaparoscopic esophagectomy for patients with esophageal cancer.

METHODSBetween January 2013 and January 2014, the feasibility of no nasogastric intubation and early oral feeding at postoperative day(POD) 1 after thoracolaparoscopic esophagectomy was prospectively investigated in 156 patients (trial group) with esophageal cancer in the Henan Cancer Hospital. One hundred and sixty patients previously managed in the same unit who were treated routinely after thoracolaparoscopic esophagectomy were served as control group.

RESULTSOf 156 patients of trial group, 6(3.8%) patients could not take food early as planned because of postoperative complications. The overall complication rate in trial group was 19.2%(30/156), which was 25.0%(30/160) in control group (P=0.217). The anastomotic leakage in trial group and control group was 2.6%(4/156) and 4.3%(7/160) respectively (P=0.380). Compared with control group, time to first flatus [(2.1±0.9) d vs. (3.3±1.1) d, P<0.001], bowel movement [(4.4±1.3) d vs. (6.6±1.0) d, P<0.001] and postoperative hospital stay [(8.3±3.2) d vs. (10.4±3.6) d, P<0.001] were significantly shorter in trial group.

CONCLUSIONSNo nasogastric intubation and early oral feeding postoperatively in patients with thoracolaparoscopic esophagectomy is feasible and safe. This management can shorten postoperative hospital stay and fasten postoperative bowel function recovery.

Background and objective Mediastinal lymphoma or right upper lung cancer is a common cause of superior vena cava obstruction syndrome (SVCOS). Endobronchial ultrasound-guided needle aspiration (EBUS-TBNA) biopsy is applied for the diagnosis of mediastinal mass disease. hTe aim of this study is to explore the safety and feasibility of EBUS-TBNA biopsy under general anesthesia for the clinical diagnosis of SVCOS. Methods Twenty-ifve cases of SVCOS re-ceived EBUS-TBNA under general anesthesia between June 2012 and June 2013. hTe group consisted of 16 male and 9 female patients aged 33 years to 76 years, with a median age of 62.5. Results Twenty-four cases were conifrmed to be of malignant pathology, and one case failed to yield a clear pathological diagnosis. No patient experienced any complications related to the operation, such as heavy bleeding and pneumothorax. Conclusion For patients presenting with SVCOS, EBUS-TBNA under general anesthesia is a safe and reliable inspection method of high diagnostic yield. hTis method can be used for routine exami-nation when other means cannot obtain clear pathological diagnosis.

Objective To perform a nationwide external quality assessment for detection of Chlamydia trachomatis, and to improve the performance of laboratories in the detection of Chlamydia trachomatis. Methods Totally, 419 quality control samples were sent to tested laboratories, including 76 samples in 2007, 168 samples in 2008 and 175 samples in 2009. The laboratories were required to test the samples and report test results, within stipulated time, to the reference laboratory in National Center for Sexually Transmitted Disease (STD) Control, Chinese Center for Disease Control and Prevention. The reported results were statistically analyzed by the National Center for STD Control, who finally fed back the statistical results to all of the participants. Results The percentage increased from 84.93% in 2007 to 92.14% in 2009 for laboratories showing an 80% or more consistency with the reference laboratory in the detection of Chlamydia trachomatis from quality control samples (qualified), from 47.95% in 2007 to 70% in 2009 for those showing a 100% consistency (excellent), and dereased from 5.48% in 2007 to 0.71% in 2009 for those showing a consistency of lower than 60% (unqualified). The centralabs of provincial CDC and volunteer laboratories exhibited a satisfactory performance for the detection of Chlamydia trachomatis, while the performance of a small number of national STD surveillance sites needed to be increase. Conclusion The external quality assessment reveals a continuous improvement in the capability of detecting Chlamydia trachomatis in STD laboratories at different levels in China.

Objective To investigate the effect of methylation inhibitor decitabine (DAC) alone and combination with As2O3 on apoptosis of NB4 cells. Methods NB4 cells were treated with DAC, As2O3 and the combination of them in different concentrations. The cell proliferation was analyzed by MTT assay and the apoptosis of NB4 cells was detected by flow cytometry. Results Both DAC and As2O3 induced time and concentration-dependent cell death, in which the inhabitation rate were 12.18 %, 22.72 %, 35.54 %, respectively, after 24 h, 48 h, 72 h on treatment by DAC at 1 μmol/L and the inhibition rates were increased to 22.14 %, 31.18 %, 45.21 % by DAC at 1 μmol/L. The inhibition rates were 21.09 %, 32.43 %, 44.93 %, respectively, by treating with As2O3 0.5 μmol/L after 24 h, 48 h, 72 h, which were increased to 31.69 %, 41.12 % and 54.27 %, respectively after 24 h, 48 h, 72 h. The inhibition rates were significantly increased by using both DAC and As2O3 with significant differences (P <0.05). DAC and As2O3 in combination produced a greater inhibition of growth against NB4 cells (by treating with DAC 1 μmol/L + As2O3 0.5 μmol/L after 24 h, 48 h, 72 h, the inhibition rates were 42.10 %, 48.75 %, 60.78 %) (P <0.05). In each concentration group and control group the differences were statistically significant (P <0.05). The incubation for 48 h with As2O3 1 μmol/L alone or combined with DAC 2 μmol/L showed apoptosis cells by 5.8 % and 17.3 %. Conclusion Decitabine can significantly inhibit the proliferation of NB4 cells and the apoptosis with synergistic effectiveness can be found when Decitabine combination with As2O3.
