Objective:To evaluate the effectiveness of oral-nasal oxygen supply mouth guard in painless gastroscopy for snoring patients.Methods:The snoring patients who underwent painless gastroscopy at two Endoscopy Centers of Shanghai East Hospital, Tongji University in July 2022 were randomly divided into the observation group (using oral-nasal oxygen supply mouth guard) and the control group (using ordinary nasal oxygen tube and mouth guard). Parameters such as the wearing time and the removal time of the mouth guard, lowest pulse oxygen saturation (SpO 2), incidence of hypoxemia, and the satisfaction of medical staff were compared between the two groups. Results:The wearing time of mouth guard was 11.63±0.84 seconds and the removal time was 5.33±0.76 seconds in the observation group ( n=40), which were lower than those in the control group ( n=47) (14.91±1.21 seconds, t=-14.463, P<0.001; 10.38±0.80 seconds, t=-30.095, P<0.001). The wearing satisfaction score was 9.80±0.61, the lowest SpO 2 was (96.70±3.42)%, the removal satisfaction score was 9.75±0.67, and the anesthesiologists' satisfaction score was 9.20±1.42 in the observation group, which were higher than those in the control group [7.70±0.93, t=12.209, P<0.001; (94.06±3.72)%, t=3.417, P=0.001; 7.96±0.98, t=9.803, P<0.001; 8.13±1.35, t=3.615, P=0.001] with significant difference. There was no significant difference in the incidence of hypoxemia [10.00% (4/40) VS 14.89% (7/47), χ2=0.130, P=0.718] and endoscopic physician satisfaction score (9.30±0.97 VS 9.02±1.31, t=1.112, P=0.269) between the two groups. Conclusion:The oral-nasal oxygen supply mouth guard is easy to wear and remove, effectively reducing SpO 2 fluctuations during painless gastroscopy for snoring patients. It can enhance medical staff satisfaction with high clinical value.

To investigate the effects of streptavidin and dimethylsilicone oil on the detection rate of microscopic lesions under gastroscopy, a total of 353 patients who underwent painless gastroscopy were categorized into the experimental group (given streptavidin combined with sodium bicarbonate, n=176) and the control group (given dimethylsilicone oil combined with sodium bicarbonate, n=177). Clinical indexes such as visual field clarity, examination duration, number of rinses, detection rate of micro lesions, early cancer detection rate and incidence of adverse reactions were recorded in the gastroscopy examination of the two groups. The experimental and control groups were compared in terms of visual field clarity (1.84±0.51 points VS 2.15±0.48 points, t=-5.900), fundus mucus properties (1.04±0.43 points VS 1.46±0.76 points, t=-6.347) and number of rinses (0.76±0.66 times VS 1.18±0.72 times, t=-5.628) with significant differences ( P<0.001). The examination time in the experimental group was slightly higher than that in the control group (10.01±4.40 min VS 8.98±4.22 min, t=2.239, P=0.026). The detection rate of microscopic lesions was significantly higher in the experimental group than that in the control group [97.73%(172/176) VS 91.53%(162/177), χ2=6.665, P=0.010]. There was no significant difference in the detection rate of inflammatory hyperplasia, polyps, precancerous lesions or cancer between the experimental group and the control group ( P>0.05). There was no preoperative drinking discomfort in either group, and 4 cases of intraoperative choking occurred in each of the experimental and the control group with no significant difference ( P>0.999). No postoperative adverse reaction occurred in either group. Taking streptavidin before operation could significantly improve visual field clarity and the detection rate of microscopic lesions, which helps to detect early lesions in stomach.

To evaluate the clinical value of a new method of guide wire extraction and single reverse-α fixation with short nasobiliary duct for oronasal conversion and fixation, patients who underwent endoscopic nasobiliary drainage in Shanghai East Hospital, Tongji University from January to August 2022 were selected. They were randomly divided into guide wire extraction and single reverse-α fixation with short nasobiliary duct group (the observation group, n=145) and guide wire taking and reverse-α fixation group (the control group, n=71). The operation time, one-time operation success rate, adverse events, comfort and satisfaction between the two groups were compared. The operation time in the observation group was significantly shorter than that in the control group [102 ( 91, 117) s VS 136 (127, 145) s, Z=-9.639, P<0.001]. The one-time operation success rate in the observation group was significantly higher than that in the control group [88.28% (128/145) VS 67.61% (48/71), χ2=13.496], the nasopharynx stimulation score [1 (1, 2) VS 2 (1, 2), Z=-4.457] and adverse events incidence [4.14% (6/145) VS 15.49% (11/71), χ2=8.475] in the observation group were significantly lower than those in the control group ( P<0.05). During the indwelling of nasobiliary duct, the bile drainage volume (179.45±81.54 mL VS 142.89±55.69 mL, t=3.407) and nursing satisfaction score (7.72±0.99 VS 6.06±1.07, t=11.337) in the observation group were higher than those in the control group, and the comfort score (3.00±1.01 VS 4.83±0.99, t=-12.642) and incidence of adverse events [3.45% (5/145) VS 14.08% (10/71), χ2=8.344] in the observation group were lower than those in the control group ( P<0.05). The operation time of nasobiliary duct removal in the observation group was significantly shorter than that in the control group (9.00±1.14 s VS 11.93±1.36 s, t=-16.616, P<0.001). In conclusion, the guide wire extraction and single reverse-α fixation with short nasobiliary duct for nasobiliary oronasal conversion and fixation in endoscopic nasobiliary drainage has the advantages of simple operation, small irritation response and low complication incidence, which is worth of clinical promotion.

Objective To compare the tracing effects of radionuclide and barium sulfate on lactulose hydrogen breath test (LHBT), and to explore the value of LHBT combined with radionuclide imaging in the diagnosis of small intestinal bacterial overgrowth (SIBO) in patients with irritable bowel syndrome (IBS).Methods From November 2010 to November 2012, 89 patients (47 males, 42 females;mean age (45.7±12.9) years) with IBS and 13 healthy volunteers (9 males, 4 females;mean age (43.3±8.6) years) were enrolled in this prospective study.All the subjects underwent LHBT combined with radionuclide imaging.Recording the time when the increment of H2 value >0.005‰ and the OCTT of the radionuclide.Four healthy volunteers also underwent LHBT combined with barium sulfate 1 week after radionuclide imaging.The location of barium sulfate was recorded when H2 value increment >0.020‰.Patients with SIBO received rifaximin treatment, and the effect was observed.χ2 test, Pearson correlation analysis and Wilcoxon rank sum test were used to analyze the data.Results (1)In LHBT combined with barium sulfate test, barium sulfate was found still stagnating in small intestine by abdominal X-ray when H2 value increment >0.020‰ in 4 healthy volunteers, and barium sulfate didn′t reach the colon in delayed imaging in 1 patient.(2) The rates of SIBO detected by LHBT in IBS patients and healthy volunteers were significantly different (43.8%(39/89) vs 5/13;χ2=0.133, P=0.716), and those detected by LHBT combined with radionuclide imaging were also significantly different (39.3%(35/89) vs 1/13;χ2=4.970, P=0.026).(3)The time of H2 value increased >0.005‰ correlated well with OCTT in 13 healthy volunteers ((73±31) and (50±19) min;r=0.871, P<0.001) and 54 IBS patients without SIBO ((83±34) and (66±28) min;r=0.735, P<0.001), but there was no correlation in 35 IBS patients with SIBO ((36±30) and (75±30) min;r=0.304, P=0.076).(4)A total of 34 SIBO-positive patients received a rifaximin treatment, with a significant improvement in the frequency of abdominal pain and abdominal distension after the treatment according to Rome Ⅲ diagnostic criteria: 5(4, 6) vs 4(3, 5), 4(1, 6) vs 0(0, 4)(z values:-4.842 and-5.388, both P<0.001).Conclusion LHBT alone is not a valid test for SIBO, and LHBT combined with radionuclide imaging is a good candidate for SIBO diagnosis.

OBJECTIVETo examine the effect of parents' occupational and life exposure during six months before pregnancy on executive function of preschool children.

METHODSPregnant women involved in the study came from the Ma'anshan Birth Cohort Study,a part of the China-Anhui Birth Cohort Study. Between October 2008 and October 2010, pregnant women who accepted pregnancy care in four municipal medical and health institutions in Ma'anshan city were recruited as study objects. A total of 5,084 pregnant women and 4,669 singleton live births entered in this cohort. Between April 2014 and April 2015, a total of 3,803 pre-school children were followed up. Finally, except 32 preschool children did not have EF evaluation result, there were 3,771 children included in this study. By using self-designed " Maternal health handbook", we researched parents' general demographic characteristics, and life and occupational exposure during six months before pregnancy. To research preschool children's executive function, we used the Behavior Rating Inventory of Executive Function-Preschool Version (BRIEF-P). Univariate and multivariate statistical method was used to analyze the association of parents' life and occupational exposure during six months before pregnancy and preschool children's EF.

RESULTS3,771 preschool children's detected rate of inhibitory self-control index (ISCI), flexibility index (FI), emergent metacognition index (EMI) and global executive composite (GEC) dysplasia were 4.8% (182), 2.3% (88), 16.5% (623) and 8.6% (324) respectively. During six months before pregnancy, children whose parents were lived in a noise environment (OR=1.86, 95% CI: 1.36-2.54), whose maternal were exposed to pesticides were the risk of ISCI dysplasia(OR=3.60, 95% CI: 1.45-8.95). During six months before pregnancy, children whose maternal were exposed to pesticides (OR=6.72, 95% CI: 2.50-18.07) and whose father were exposed to occupational lead (OR=2.10, 95% CI: 1.25-3.54) were the risk of FI dysplasia. During six months before pregnancy, children whose parents were lived in a noise environment (OR=1.42, 95%CI: 1.18-1.71) and whose father were exposed to occupational lead (OR=1.30, 95%CI: 1.02-1.65) were the risk of EMI dysplasia. During six months before pregnancy, children whose parents were lived in a noise environment (OR=1.58, 95% CI: 1.24-2.01) and whose maternal were exposed to pesticides (OR=2.39, 95% CI: 1.02-5.58) were the risk of GEC dysplasia.

CONCLUSIONThe development of executive function is worse among preschool children whose parents live in noise environment, mother exposed to pesticides, and father exposed to occupational lead during six months before pregnancy.

OBJECTIVETo investigate the related influencing factors of preschool children's emotional and behavioral problems in early life and explore the associations between the symptoms of depression or anxiety during pregnancy and emotional and behavioral problems in preschool children.

METHODSBased on the Ma'anshan Birth Cohort Study of the China-Anhui Birth Cohort Study (C-ABCS), women were recruited at their first clinical visit between October 2008 and October 2010 in four municipal medical and health institutions of Ma'anshan City, a total of 5 084 pregnant women and 4 669 singletons live births were included in the birth cohort. Women completed measures of depressive (Self-Rating Anxiety scale) and anxious (Center for Epidemiologic Studies Depression) symptoms in pregnancy. By the age of 3-6 follow-up, 3 653 children were followed with completed information between April 2014 and April 2015, strengths and difficulties questionnaires were used to assessed offspring emotional and behavioral problems. Logistics regression was used to investigate the relationship between the symptoms of depression or anxiety during pregnancy and emotional and behavioral problems in preschool children.

RESULTSThe detected rates of emotional symptoms, conduct problems, hyperactivity and peer problems in preschool children were 6.3% (229/3 653), 7.5% (274/3 653), 7.6% (278/3 653) and 2.8% (103/3 653), while 7.6% (277/3 653) for total difficulties, 10.9%(398/3 653) for prosocial behavior and 27.4%(981/3 557) for impact respectively. Prevalence of anxiety and depression in the first trimester was 2.7%(100/3 653) and 4.7%(171/3 653) respectively, and in the second trimester was 2.0%(66/3 375) and 3.6%(122/3 375) respectively. After we controlled the confoundings of gestation age, place of residence, family income, maternal education, paternal education, premature birth and folic acid supplement before pregnancy, multinomial logistic regression analysis showed that the risk of children's emotional symptoms in maternal anxiety in both first-trimester and second-trimester group was higher than the group of no depression and anxiety symptoms, and OR(95%CI) was 5.90(2.00-17.48). Compared with whose mother no depression in both first-trimester and second-trimester, the risk of children's emotional symptoms in maternal depression in both first-trimester and second-trimester group was higher, and OR(95% CI) was 3.07 (1.30-7.28). And the risk of children's total difficulties of maternal anxiety in second-trimester was 2.27 (95%CI: 1.10-4.71) times of no anxiety in second-trimester. While the risk of children's total difficulties of maternal depression in second-trimester was 2.20 (95%CI: 1.24-3.93) times of no depression in second-trimester. Maternal emotional symptoms were not significant associations with conduct problems, hyperactivity, peer problems and prosocial behaviors (P> 0.05).

CONCLUSIONThere was a negative impact of maternal anxiety and depression symptoms during pregnancy on emotional and behavioral problems in preschool children. These findings highlight the need for additional clinical and research attention to both maternal depression and anxiety in pregnancy, which may be helpful to reduce the incidence of children's emotional and behavioral problems and act as an important measure in prevention.

OBJECTIVETo examine the effect of maternal pre-pregnancy body mass index (BMI) and gestational weight gain (GWG) with childhood overweight and adiposity, and to explore possible early life risk factors for obesity in preschool children.

METHODSBasic information of pregnant women and gestation period came from the Ma'anshan Birth Cohort Study, a part of the China-Anhui Birth Cohort Study (C-ABCS). Pregnant women in routine health care from four municipal medical and health institutions were enrolled voluntarily during October 2008 and October 2010 in Ma'anshan City. A total of 5 084 pregnant women and 4 669 singleton live births were included in this study. Between April 2014 and April 2015, 3 797 children were followed up. Children whose BMI were >85th percentiles for age and genders of World Health Organization (WHO) reference were considered as overweight, and >95th percentiles for age and genders cut-off values were considered as obesity (pathological and secondary causes of obesity were excluded). Gestational weight gain was defined according to the Institute of Medicine (IOM) guidelines. Univariate and binary regression model analysis was used to examine the effect of pre-pregnancy BMI and GWG with childhood overweight and adiposity.

RESULTSOf the 3 797 pregnant women, the prevalence of underweight, normal weight, overweight and obesity were respectively 22.6% (n=858), 70.3% (n=2 671), 6.2% (n=234) and 0.9% (n=34). There were 3 563 pregnant women who were obtained gestational weight gain data, the prevalence of inadequate GWG, appropriate GWG, excessive GWG were respectively 12.4% (n=443), 25.9% (n=922) and 61.7% (n=2 198). The prevalence of overweight and obesity were 11.5% (n=437) and 10.8% (n= 411) in preschool children, respectively. After adjusting confounding factors including age at delivery, genders of children, children age, birth weight, breastfeeding and household economic status, binary logistic regression analysis showed that pre-pregnancy overweight and obesity(OR=2.01, 95% CI: 1.53-2.65), excessive GWG(OR=1.65, 95% CI: 1.35-2.03) were risk factors for overweight and obesity, and pre-pregnancy underweight was protective factor for childhood overweight and obesity (OR=0.49, 95% CI: 0.39-0.62). Joint associations of pre-pregnancy BMI and inappropriate GWG were also noticed in the study: compared to only pre-pregnancy higher BMI or excessive GWG or indequate GWG, combination of high pre-pregnancy BMI and excessive GWG or high pre-pregnancy BMI and inadequate GWG, adverse effects on childhood overweight and obesity were much higher,OR (95%CI) values were 2.90(1.97-4.28), 3.17(1.44-6.97) respectively.

CONCLUSIONBoth high pre-pregnancy BMI and inappropriate GWG are associated with greater offspring BMI. Pregnant women should achieve appropriate weight gain and help prevent obesity in their children.

OBJECTIVETo analyze the associations between pregnancy-related anxiety and the prevalence of subthreshold autism trait (SAT) in preschool children.

METHODSBaseline data came from the Ma'anshan Birth Cohort Study, a part of the China-Anhui Birth Cohort Study (C-ABCS). All the participants were enrolled among pregnant women who received prenatal health care in 4 municipal medical centers during Oct. 2008 to Oct. 2010. A total of 5 084 pregnant women were recruited at the beginning and 4 669 singleton live births were included until childbirth. The situation about pregnancy-specific anxiety during trimester and third trimester of women were evaluated by Pregnancy-specific Anxiety Questionnaire (PAQ). Between April 2014 and April 2015, the cohort was followed up again, and the Clancy Autism Behavior Scale (CABRS) filled out by parents was used for telling the SAT children from the healthy children among 3 663 preschool children. Univariate and binary regression model was used to estimate associations between the pregnancy-related anxiety during trimester and third trimester and the subthreshold autism trait in children.

RESULTSDuring the pregnancy, the detected rates of women with pregnancy-specific anxiety in trimester and the third trimester were 25.5%(935/3 663), 13.9%(501/3 592) respectively, and the detected rate of maternal pregnancy-specific anxiety in both periods was 7.7%(278/3 592). There were 290 positive children with SAT and the detection rate was 7.9%. After controlling possible confounding factors including children's genders, place of residence, supplement folic acid during pregnancy, preterm birth, exposure to second-hand smoke during pregnancy, the father (mother) cultural levels, the father (mother) nature of work and family income, the results of multinomial logistic regression analysis showed that maternal pregnancy-specific anxiety in trimester was the risk factor for SAT in preschool children (OR=1.51, 95% CI: 1.11-2.04), and there was no association between maternal pregnancy-specific anxiety in the third trimester and SAT in preschool children (OR=1.36, 95% CI: 0.82-2.22). Compared with the single function of maternal pregnancy-specific anxiety in trimester or the third trimester for SAT in preschool children, maternal pregnancy-specific anxiety in both periods presented a joint action that increasing the risk for SAT (OR=2.02, 95% CI: 1.36-2.98).

CONCLUSIONMaternal pregnancy-related anxiety was a risk factor for subthreshold autism trait in preschooler children. Pregnant women should try to keep a good mental state to create a good environment for fetal growth.

Objective To investigate the risk factors of delayed hemolysis after treatment in patients with malaria .Methods Eighty-nine cases of malaria were retrospectively analyzed .The incidence rate , time from treatment to delayed hemolysis and clinical features of delayed hemolysis after treatment in patients with malaria were investigated .The characteristics of demography ,etiology and laboratory data were compared between delayed hemolysis group and non-delayed hemolysis group .The t test ,χ2 test and Fisher exact test were used for comparison between groups .Results A total of 89 cases of malaria infection were included and 8 cases were diagnosed with delayed hemolysis after treatment among them , with incidence rate of 8 .99% .Patients developed delayed hemolysis after anti-malarial treatment with a median of 7 .5 d and patients recovered from hemolysis after the usage of glucocorticoid with a median of 2 .5 d .The 8 cases were all infected with Plasmodium f alciparum ,and 4 of which had high parasitemia . None of the patients with delayed hemolysis came from epidemic area ,while 28 of the patients without non-delayed hemolysis came from epidemic area .The difference was statistically significant (P=0 .042 , Fisher unilateral exact test) .The average level of minimum hemoglobin was (44 .87 ± 11 .58) g/L in patients with delayed hemolysis ,which was significantly lower than that of non-delayed hemolysis group (108 .35 ± 19 .72) g/L (t= -8 .923 , P< 0 .01) .Conclusion Plasmodium falciparum infection , hyperparasitemia and having no immunity against malaria may be risk factors of delayed hemolysis after treatment .

Objective To investigate the potential role of Lycium bararum polysaccharide (LBP) with or without interferon -inducible protein 10 ( CXCL10) in inducing dendritic cells ( DC) functional maturation by monitoring the alteration of cytokines for inducing DC maturation in peripheral blood and by detecting the expression of S-100 protein in tumor tissue, thus to reveal its mechanism of inhibiting experimental liver cancer. Methods H22 bearing mice model was established. The mice were randomized into model group, LBP group (50 mg/kg, ig), CXCL10 (right axillary subcutaneous injection of 15 μg/kg), LBP + CXCL10 group (LBP 50 mg/kg, ig, and right axillary subcutaneous injection of CXCL10 15 μg/kg), 5- fluorouracil (5FU) group ( intraperitoneal injection of 12mg/kg) , 12 mice in each group. The mice were administered the corresponding medicine once a day. After treatment for 2 continuous weeks, blood was sampled from infraorbital vein, and the tumor mass, spleen, thymus were extracted for the calculation of anti-tumor rate, thymus index and spleen index separately . The mRNA expression levels of interleukin 12 (IL-12) and tumor necrosis factor-α (TNF-α) in peripheral blood were detected by fluorescence quantitative PCR, the expression of S-100 protein in tumor tissues was detected by immunohistochemical assay. Results Compared with the model group, tumor growth in LBP group and LBP+CXCL10 group was obviously inhibited, and tumor-inhibitory rate was 55.90%, 50.91%, respectively. Meanwhile, the mRNA expression level of IL-12 was 2.94 folds higher in LBP group and 3.39 folds higher in LBP + CXCL10 group, and TNF-α mRNA expression level was 1.55 folds higher in LBP group and 4.74 folds higher in LBP+CXCL10 group than the model group, the differences being statistical significant ( P<0.05 or P<0.01). Results of immunohistochemical assay showed that S-100+DC number in LBP group and LBP+CXCL10 group was larger than that in the model group (P<0.05 ). Conclusion LBP and LBP+CXCL10 exert significant effect on inhibiting experimental liver cancer. The mechanism may be related with inducing the secretion of IL-12 and TNF-α, which plays a key role in inducing DC maturation, and with the increase of the number of DC in tumor microenvironment.
