Abstract
Objective: To investigate the relationship between genetic polymorphisms of cytochrome P450 2C19 (CYP2C19) and the efficacy of Helicobacter pylori (Hp) eradication therapy in children. Methods: The retrospective cohort study was conducted on 125 children with gastroscopy and positive rapid urease test (RUT) from September 2016 to December 2018 who presented to the Children's Hospital of Zhejiang University School of Medicine due to gastrointestinal symptoms including nausea, vomiting, abdominal pain, bloating, acid reflux, heartburn, chest pain, vomiting blood and melena. Hp culture and drug susceptibility test were carried out with gastric antrum mucosa before treatment. All the patients completed 2 weeks of standardized Hp eradication therapy and had 13C urea breath test 1 month after that, which was used to evaluate the curative effect. The DNA of gastric mucosa after RUT was analyzed and CYP2C19 gene polymorphism was detected. Children were grouped according to metabolic type. Combined with the results of Hp culture and drug susceptibility, the relationship between CYP2C19 gene polymorphism and the efficacy of Hp eradicative treatment was analyzed in children. Chi square test was used for row and column variables, and Fisher exact test was used for comparison between groups. Results: One hundred and twenty five children were enrolled in the study, of whom 76 were males and 49 females. The genetic polymorphism of CYP2C19 in these children found poor metabolizer (PM) of 30.4% (38/125), intermediate metabolizer (IM) of 20.8% (26/125), normal metabolizer (NM) of 47.2% (59/125), rapid metabolizer (RM) of 1.6% (2/125), and ultrarapid metabolizer (UM) of 0. There were statistically significant in positive rate of Hp culture among these groups (χ2=124.00, P<0.001). In addition, the successful rates of Hp eradication in PM, IM, NM and RM genotypes were 84.2% (32/38), 53.8% (14/26), 67.8% (40/59), and 0, respectively, with significant differences (χ2=11.35, P=0.010); those in IM genotype was significantly lower than that in PM genotype (P=0.011). With the same standard triple Hp eradicative regimen, the successful rate of Hp eradication for IM type was 8/19, which was lower than that of PM (80.0%, 24/30) and NM type (77.3%, 34/44) (P=0.007 and 0.007, respectively). There was a significant difference in the efficacy of Hp eradication treatment among different genotypes (χ2=9.72, P=0.008). According to the clarithromycin susceptibility result, the successful rate of Hp eradication treatment for IM genotype was 4/15 in the sensitive group and 4/4 in the drug-resistant group (χ2=6.97, P=0.018). Conclusions: The genetic polymorphism of CYP2C19 in children is closely related to the efficacy of Hp eradication treatment. PM has a higher successful rate of eradication treatment than the other genotypes.

Abstract
This study aimed to investigate the effects of Erxian Decoction(EXD)-containing serum on the proliferation and osteogenic differentiation of MC3T3-E1 cells under oxidative stress through BK channels. The oxidative stress model was induced in MC3T3-E1 cells by H_2O_2, and 3 mmol·L~(-1) tetraethylammonium(TEA) chloride was used to block the BK channels in MC3T3-E1 cells. MC3T3-E1 cells were divided into a control group, a model group, an EXD group, a TEA group, and a TEA+EXD group. After MC3T3-E1 cells were treated with corresponding drugs for 2 days, 700 μmol·L~(-1) H_2O_2 was added for treatment for another 2 hours. CCK-8 assay was used to detect cell proliferation activity. The alkaline phosphatase(ALP) assay kit was used to detect the ALP activity of cells. Western blot and real-time fluorescence-based quantitative PCR(RT-qPCR) were used to detect protein and mRNA expression, respectively. Alizarin red staining was used to detect the mineralization area of osteoblasts. The results showed that compared with the control group, the model group showed significantly blunted cell proliferation activity and ALP activity, reduced expression of BK channel α subunit(BKα), collagen Ⅰ(COL1), bone morphogenetic protein 2(BMP2), osteoprotegerin(OPG), and phosphorylated Akt, decreased mRNA expression levels of Runt-related transcription factor 2(RUNX2), BMP2, and OPG, and declining area of calcium nodules. EXD-containing serum could significantly potentiate the cell proliferation activity and ALP activity, up-regulate the protein expression of BKα, COL1, BMP2, OPG, and phosphorylated Akt, and forkhead box protein O1(FoxO1), promote the mRNA expression of RUNX2, BMP2, and OPG, and enlarge the area of calcium nodules. However, BK channel blockage by TEA reversed the effects of EXD-containing serum in promoting the protein expression of BKα, COL1, BMP2, OPG, and phosphorylated Akt and FoxO1, increasing the mRNA expression of RUNX2, BMP2, and OPG, and enlarging the area of calcium nodules. EXD-containing serum could improve the proliferation activity, osteogenic differentiation, and mineralization ability of MC3T3-E1 cells under oxidative stress, which might be related to the regulation of BK channels and downstream Akt/FoxO1 signaling pathway.

Abstract
Objective: To analyze the gender differences of genetic etiology in the incidence of major depression disorder among Han freshmen. Methods: A 1-year follow-up survey was carried out among 8 079 Han freshmen from Jining, Rizhao and Weifang without lifetime major depressive disorder (MDD) at baseline (April to October 2018) and 4 828 venous blood samples were also collected. After extracting DNA, Sequenom Mass Array time-of-flight mass spectrometry biochip technology was used to detect the genotypes of 17 single nucleotide polymorphisms (SNPs) MDD-related loci. Logistic regression was used for univariate analysis. Generalized multifactor dimension reduction was used to analyze gene-gene interactions. Composite International Diagnostic Interview (CIDI) 3.0 was used for MDD diagnosis. Results: The 1-year incidence of MDD among Han freshmen was 2.23% (95%CI: 1.91%-2.60%) and the gender difference of incidence between males (1.97%, 95%CI: 1.52%-2.56%) and females (2.39%, 95%CI: 1.98%-2.90%) was not statistically significant (P>0.05). AG genotype of rs768705 (nearby gene: TMEM161B) was a risk factor for MDD (OR=1.98, 95%CI: 1.24-2.83). The TC genotype of rs17727765 (nearby gene: CRYBA1) was only a risk factor for MDD in males (OR=9.61, 95%CI: 2.04-45.30). An 8-loci interaction model (PMFBP1, OLFM4, LHPP, ENOX1, TMEM161B, SPPL3, FBXL4 and L3MBTL2) could predict MDD in women with an accuracy rate of 60.05%. No effective prediction model was found for MDD in men. Conclusions: There might be gender differences in the genetic etiology of MDD. Further researches on the genetic causes of MDD in men should be explored.

Abstract
Metal precursors employed in the bottom-up synthesis of metal nanoclusters (NCs) are of great importance in directing their composition and geometrical structure. In this work, a silver nanocluster co-protected by phosphine and thiolate, namely, [Ag39(PFBT)24(TPP)8]2- (Ag39, PFBT = pentafluorobenzenethiol, TPP = triphenylphosphine), was isolated and structurally characterized. It adopts a three-layered Ag13@Ag18@Ag8S24P8 core-shell structure. The Ag13@Ag18 kernel is unusual in multilayer noble metal NCs. By introducing a copper precursor in the synthesis, a bimetallic nanocluster [Ag37Cu2(PFBT)24(TPP)8]2- (Ag37Cu2) with an identical structure to Ag39 apart from two outer Ag atoms being substituted by Cu atoms was obtained. Astoundingly, the Cu precursor used in the synthesis was found to be critical in determining the final structure. The alteration of the Cu precursor led to the cocrystallization of the above alloy nanocluster with a Ag14 nanocluster, namely, [Ag37Cu2(PFBT)24(TPP)8]2-·[Ag14(PFBT)6(TPP)8] (Ag37Cu2·Ag14). The electronic structure analyzed by theoretical calculation reveals that Ag39 is a 17-electron open-shell superatom. The optical absorption of Ag39, Ag37Cu2, and Ag37Cu2·Ag14 was compared and studied in detail. This work not only enriches the family of alloy metallic nanoclusters but also provides a metal NC-based cocrystal platform for in-depth study of its crystal growth and photophysical property.

Abstract
This study was conducted to determine the effect of Moringa oleifera stem (MOS) meal in ducks. A total of 225 ducklings at 1 D of age were randomly assigned to 3 dietary treatment groups with 3 replicates of 25 each. The growth experiment lasted 63 D . The egg experiment started from 23 to 27 wk of age. Ducks were randomly divided into 3 treatment groups with 3 replications of 15 each. The following dietary treatments were applied: 1) Control (CON), basal diet + 0% MOS meal; 2) basal diet + 2% MOS meal; 3) basal diet + 4% MOS meal. During 0 to 4 wk of age, ducks fed 2% MOS diet showed significantly increase in average daily feed intake (ADFI) and average daily gain (ADG; P < 0.05) and ducks fed 4% MOS diet had a significant improvement in feed conversion rate (FCR; P < 0.05). However, ADFI, ADG, and FCR were not affected significantly during 5 to 9 wk of age (P > 0.05). In egg production experiment, ADFI, average egg weight, laying rate, and FCR showed significant increase in 4% MOS diets (P < 0.05). Laying ducks fed 4% MOS diet had a higher egg shape index, whereas a lower yolk color compared with CON (P < 0.05). The proportion of broken shell eggs were zero in experimental diets, whereas 3% of which occurred in CON (P < 0.05). However, no significant effects in proportion of soft shell eggs, proportion of abnormal-shape eggs, albumen height, haugh unit, and eggshell thickness were observed among all treatments (P > 0.05). For serum biochemical parameters, total protein and albumin were increased in MOS diets during 0 to 4 wk of age, but decreased during 5 to 9 wk of age. For serum antioxidant index, superoxide dismutase and glutathione peroxidase values were increased whereas malondialdehyde values were decreased in MOS diets from 0 to 9 wk of age. The results suggest that MOS positively affects early growth performance and laying performane of duckling but partially affects egg quality. The antioxidative activity and immunological index may be improved.

Abstract
We report that a 30-year-old woman with mental retardation was referred for prenatal diagnoses during pregnancy. An ultrasound scan showed that the heart structure and function of the fetus were normal. Cytogenetic analysis showed that the female karyotype was 47,XX, t(17; 22) (q21; q11), +21. The woman's husband had a normal male karyotype and was phenotypically normal. During this first pregnancy, an amniocentesis, which was done at 19 weeks, revealed that the fetal karyotype was 46,XX, t(17; 22) (q21; q11). Fluorescence in situ hybridization testing of amniotic fluid gave a normal result for chromosome 21. The child was a phenotypically normal female baby.

Abstract
BACKGROUND Cognitive dysfunction is frequently seen in neuromyelitis optica (NMO). However, the features and influencing factors of cognitive impairment of Chinese NMO patients are unclear. OBJECTIVE To investigate the patterns of cognitive impairment in Chinese NMO patients, and correlate the neuropsychiatric scores with clinical and MRI parameters. METHODS Thirty-six Chinese NMO patients, and 30 sex and age-matched healthy controls were recruited with extensive neuropsychological assessments, using the modified Minimal Assessment of Cognitive Function in MS (MACFIMS). The demographic and clinical characteristics as well as MRI parameters were compared between cognitively impaired (CI) and cognitively preserved (CP) patients. RESULTS NMO patients were significantly impaired in the Paced Auditory Serial Addition Task (P<0.05), the Symbol Digit Modalities Test (P<0.001), the California Verbal Learning Test-Second Edition (P<0.05), the Brief Visuospatial Memory Test-Revised (P<0.05) and semantic fluency (P<0.001). Only lower education level was associated with cognitive dysfunction in NMO (odds ratio: 0.57, P<0.05). There were no significant differences of MRI parameters regarding white matter (WM) lesions, grey matter and WM brain volume between CI and CP patients. CONCLUSIONS Chinese NMO patients particularly demonstrated cognitive impairment in information processing speed, executive function and memory. Lower education level was the main factor contributing to cognitive impairment in NMO.

Abstract
BACKGROUND Depression related cognitive deficits are frequently considered as simple epiphenomena of the disorder. However, whether or not the depression might directly bring about cognitive deficits is still under investigation. This study was to investigate the distinct pattern of cognitive deficits in patients with depression by comparing the cognitive function before and after anti-depressive drug therapy. METHODS Sixty cases of patients, first-time diagnosed with depression, were assessed by 17-item Hamilton Rating Scale for Depression (HAMD17scale). The memory ability was tested by quantitatively clinical memory scale, while the attention ability by modified Ruff 2&7 Selective Attention Test. Forty-two healthy volunteers were recruited as controls. The depressive patients were treated with Venlafaxine (75 - 300 mg/d), Fluoxetine (20 - 40 mg/d), Paroxetine (20 - 40 mg/d), and Sertraline (50 - 150 mg/d). After 12 weeks treatment, patients were tested again by HAMD17scale, quantitatively clinical memory scale, and modified Ruff 2&7 selective attention test to assess the effect of anti-depressive drugs on cognitive deficits. RESULTS The memory quotient (MQ) was significantly lowered in depressive patients. The selection speed was also significantly decreased and the number of missing and error hits increased in the depression group as compared to control. However, there was no significant difference in clinical memory scale and Ruff 2&7 selective attention test between mild-to-moderate and severe depression group. Importantly, after anti-depressive drug therapy, the HAMD17 scale scores in depressive patients were significantly decreased, but the MQ, directional memory (DM), free recall (FR), associative learning (AL), and face recognition were comparable with those before the treatment. Furthermore, the selection speed and the number of missing and error hits were also not significantly different after anti-depressive drugs treatment. CONCLUSIONS Depressive patients suffer from short-term memory deficits, and attention extent, stability and rearrangement deficiency. Even though anti-depressive drugs sufficiently relieve the cardinal presentation of depression, they could not successfully alleviate the accompanying cognitive deficits. This might indicate a distinct pattern of cognitive deficits in patients with depression.

Abstract
An eluting-stent system with mAb dispersed in the PLLA (poly (L-lactic acid)) was validated in vitro. Specifically designed spray equipment based on the principle of ultrasonic atomization was used to produce a thin continuous PLLA (poly (L-lactic acid)) polymer coating incorporating monoclonal antibody (mAb). This PLLA coating was observed in light microscopy (LM) and scanning electron microscopy (SEM). The concentration of the monoclonal antibody (mAb) to the platelet glycoprotein (GP) IIIa receptor and the eluting rate were then measured by a radioisotope technique with (125)I-labelled GP IIIa mAb. An in vitro perfusion circuit was designed to evaluate the release rates at different velocities (10 or 20 ml min(-1)). The PLLA coating was thin and transparent, uniformly distributed on the surface of the stent. Three factors influenced its thickness: PLLA concentration, duration and gas pressure. The concentration of mAb was influenced by the duration of absorption and the concentration of the mAb solution; the maximum was 1662.23 + or - 38.83 ng. The eluting rate was fast for the first 2 h, then decreased slowly and attained 80% after 2 weeks. This ultrasonic atomization spray equipment and technological process to prepare protein eluting-stents were proved to be effective and reliable.

Abstract
Tea is the most consumed beverage in the world. Tea polyphenols are the major constituents of tea leaves and have shown many potential healthy benefits. However, whether tea polyphenols influence ovarian follicle assembly and development and ovarian life span is unknown. To study the effect of tea polyphenols on ovarian follicle development and oocyte apoptosis, we investigated rat ovarian development of different ages [from postnatal day (PD)1 after birth to 10 months] after treatment with tea polyphenols. Our data showed that the percentage of unassembled follicles increased in the ovaries of 1- and 2-day-old rats which were ip injected with tea polyphenols (50 mg/kg/d) or whose mothers were treated with tea polyphenols (100 mg/kg/d) by intragastric administration from the day 11 after the detection of vaginal plug till delivery. The percentage of primordial follicles increased, while that of developing follicles decreased in the ovaries of 4- and 8-day-old rats following peritoneal injection with tea polyphenols compared with controls. The ratio of terminal deoxynucleotidyltransferase-mediated dUTP nick-end labeling (TUNEL)-positive oocytes decreased in the ovaries of neonatal rats following tea polyphenol treatment. In the 3- and 10-month-old rat ovaries, the number of primordial follicles augmented, whereas that of atretic follicles decreased after the treatment for 4 weeks. These data suggest that tea polyphenols may inhibit the transition from primordial to developing follicles, extend the entire growth phase of a follicle, and reduce dominant follicle numbers per cycle to increase the reserve of germ cells, inhibit oocyte apoptosis and follicle atresia during ovarian development from birth to early aged, and retard climacterium in rats. Drinking even a small cup of tea per day may benefit to extent the productive life of ovary.

Abstract
Solid phase microextraction (SPME) is a simple, cost-effective, time-saving extraction technique. It is rapid and highly sensitive. In this study, organic acids in cigarette smoke were extracted with 85 microns polyacrylate coated fiber. Volatile and semi-volatile organic acids, such as butanoic acid, hexanoic acid, 2-furancarboxylic acid, octanoic acid, nonanoic acid, benzoic acid, phenylacetic acid, tetradecanoic acid, and hexadecanoic acid from cigarette smoke were converted to their esters by using methanolic derivatization agent. The esters were extracted by using headspace solid phase microextraction and determined quantitatively by gas chromatography with selected ion monitoring mode mass spectrometry. Qualitative analysis of 4 brands cigarette smoke demonstrated the usefulness of this analytical technique of volatile and semi-volatile acids in cigarette smoke. More than sixty organic acids were detected by using this method.

Abstract
Overexpression of wild-type p53 protein has been shown to induce arrest in the G1 stage of the cell cycle and to transactivate expression of the gene that encodes the 21-kDa Waf1/Cip1 protein, a potent inhibitor of cyclin-dependent kinase activity. p53-dependent G1 arrest is accompanied by decreased expression of the B-myb gene, a relative of the c-myb cellular oncogene. In this study we show that B-myb expression is required for cells to progress from G1 into S phase and that high levels of ectopic B-myb expression uncoupled from cell cycle regulation rescues cells from p53-induced G1 arrest even in the presence of Waf1/Cip1 transactivation and inhibition of cyclin E/Cdk2 kinase activity. Cotransfection experiments with p53 expression plasmids and expression plasmids encoding in-frame deletion mutations in B-myb coding sequences indicate that the DNA-binding domain of the B-Myb protein is required for this activity. These results provide evidence of a bypass of p53-induced Waf1/Cip1-mediated cell cycle regulatory pathways by a member of the myb oncogene family.

Abstract
Transcervical cannulation of the proximal oviduct was performed with a tube catheter and flexible guidewire under hysteroscopic guidance to evaluate and treat intramural fallopian tube obstruction in 37 patients. Hysteroscopic cannulation with direct visualization by laparoscopy was successful in 69.2% of the obstructed tubes, 77.4% of the cases. 74% of the obstructed tubes diagnosed by HSG and/or laparoscopy was patent after hydrotubation and cannulation by hysteroscopy. Transcervical cannulation of the proximal oviduct is an effective method for evaluation and treatment of cornual obstruction.

Abstract
The results of transcervical salpingography and tubal recanalization by means of modified Thurmond and Rösch's technique were reported. Proximal tubal obstruction was diagnosed in 20 infertile women by X-ray hysterosalpingography and/or laparoscopy. Our results showed that tubal recanalization was achieved in 19(95%) of 20 patients, four patients became pregnanCy following the procedure. Distal tubal diseases were seen in 8 of 20 patients. Follow up studies revealed tubal patency was maintained in 7(54%) of 13 patients. The mean radiation dosage received by the patient was 6.35mGy. Compared with Thurmond and Rösch technique the modified technique has the advantage of decreasing the time of fluoroscopy and is a safe, effective and simple method for the diagnosis and treatment of infertile women with proximal tubal obstruction.

Abstract
The effect of specific immune RNA (i-RNA) on the activity of natural killer (NK) cells in the peripheral blood of 27 newborn infants was studied by lactic dehydrogenase (LDH) release assay. Peripheral blood mononuclear cells (PBMC) were used as effector cells with K-562 tumour cells as target cells. The results showed that in the therapeutic group (n = 17) the average activity of NK cells after therapy (24.13 +/- 4.62%) was 13.67 +/- 5.79% higher than before therapy (10.47 +/- 3.57%). In the control group (n = 10) these were only 10.78 +/- 3.94% and 11.58 +/- 3.37%, the difference was not statistically significant (P > 0.05). However, NK activity in the therapeutic group and control group was markedly different (P < 0.01). The data indicate that specific i-RNA can enhance the activity of NK cells in the peripheral blood of newborn infants. Therefore, we believe that specific i-RNA may play an important role in defence against CMV infection. The mechanism of i-RNA augmenting NK cellular activity is also discussed.

Abstract
The endometrial concentration of 6-keto-PGF1 alpha and TXB2 were measured by RIA in women with Tcu-IUD induced menorrhagia (MBL greater than 80 ml) and in levonorgestrel-IUD users with oligomenorrhea or amenorrhea. Non-IUD users with normal menses (MBL less than 80 ml) were chosen as control. It was found that the Tcu-IUD group showed a significantly higher 6-keto-PGF1 alpha concentration than the other two groups (P less than 0.01). Conversely, the TXB2 concentration of levonorgestrel-IUD group was significantly higher than that of the other groups (P less than 0.05). As a result, the 6-keto-PGF1 alpha/TXB2 ratio was much higher in Tcu-IUD group (P less than 0.01). Our results indicated that the unbalance of PGI2/TXA2 ratio may be the direct cause of the IUD-induced menorrhagia.

Abstract
Ultrasonic study of tubal patency using 1.5% hydrogen peroxide as the contrast medium during hydrotubation was performed in 147 sterile women. Hysterosalpingography was also done for the same patients. In 42 cases, laparoscopic examination of the tubes was carried out to assess the accuracy of the above two diagnostic procedures. The correspondence rate between laparoscopic findings and ultrasonography was 88.0% and 60.0% with hysterosalpingography. The difference was statistically significant (P less than 0.05). Animal experiment did not reveal any untoward effect of 1.5% hydrogen peroxide on the local tissues exposed to the solution except a transient increase of lymphocyte infiltration and exudate. Regardless of its numerous advantages, neither hysterosalpingography nor ultrasonic examination can demonstrate minute pathologic changes in the lumen of the tube. The authors pointed out that ultrasonic study combined with laparoscopic examination is the best choice diagnosis for tubal abnormalities.
