Objective To compare the advantages of three-dimensional(3D) and two-dimensional(2D) ultrasound in embryo transfer. Methods A total of 319 patients accepted embryo transfter were included in this study. 2D and 3D ultrasound were used to investigate the uterine cavity and transfer distance from the fundus (TDF),respectivly. They were divided into four groups according to TDF difference(D-TDF) between 2D and 3D ultrasound(group of DTDF<3mm,group of DTDF3～5mm,group of 6～9 mm,group of DTDF≥10 mm. Pregnancy outcomes among the four groups were compared. Results Of the 319 patients, 41 were observed to have abnormal uterine cavity. For 140 patients, the TDF measured by 2D ultrasound were different from that measured by 3D ultrasound. Clinical pregnancy rate and implantation rate were found lowest in group of TDF≥10 mm mm (7.7% vs 34.1%,38.1% ,40.0% and 3.6% vs 18.2% ,21.2% ,20.0%, P <0.05). Conclusions 2D ultrasound is limit and deficient for embryo transfer, especially for the visualization of uterine cavity and location of catheter tip, however, it may be better achieved with 3D ultrasound. It is helpful to use the 3D ultrasound to place the catheter tip accurately and improve the pregnancy rate of embryo transfer.

Sequences analysis revealed Grass carp reovirus (GCRV) s10 was 909 nucleotides coding a 34 kDa protein denoted as VP7, which was determined to be a viral outer capsid protein (OCP). To obtain expressed OCP in vitro, a full length VP7 gene was produced by RT-PCR amplification, and the amplified fragment was cloned into T7 promoted prokaryotic expression vector pRSET. The recombinant plasmid,which was named as pR/GCRV-VP7,was then transformed into E.coli BL21 host cells. The data indicated that the expressed recombinant was in frame with the N-terminal fusion peptide. The over-expressed fusion protein was produced by inducing with IPTG, and its molecular weight was about 37kDa, which was consistent with its predicted size. In addition, the fusion protein was produced in the form of the inclusion body with their yield remaining steady at more than 60% of total bacterial protein. Moreover,the expressed protein was able to bind immunologically to anti-his-tag monoclonal antibody (mouse) and anti-GCRV serum (rabbit). This work provides a research basis for further structure and function studies of GCRV during entry into cells.

Grass carp reovirus (GCRV), a double stranded RNA virus that infects aquatic animals, often with disastrous effects, belongs to the genus Aquareovirus and family Reoviridea. Similar to other reoviruses, genome replication of GCRV in infected cells occurs in cytoplasmic inclusion bodies, also called viral factories. Sequences analysis revealed the nonstructural protein NS80, encoded by GCRV segment 4, has a high similarity with uNS in MRV(Mammalian orthoreoviruses), which may be associated with viral factory formation. To understand the function of the uNS80 protein in virus replication, the initial expression and identification of the immunogenicity of the GCRV NS80 protein inclusion forming-related region (335.742) was investigated in this study. It is shown that the over-expressed fusion protein was produced by inducing with IPTG at 28oC. In addition, serum specific rabbit antibody was obtained by using super purified recombinant NS80(335.742) protein as antigen. Moreover, the expressed protein was able to bind to anti-his-tag monoclonal antibody (mouse) and NS80(335-742) specific rabbit antibody. Further western blot analysis indicates that the antiserum could detect NS80 or NS80C protein expression in GCRV infected cells. This data provides a foundation for further investigation of the role of NS80 in viral inclusion formation and virion assembly.

AIM To study the effect of bioactive compounds from entomogenous fungi (BCEF0083) on sleep-wakefulness cycle and behaviour in chronic unpredictable stress model of depression in rats. METHODS The effect of BCEF0083 on sleep-wakefulness cycle and behaviour was examined in the chronic unpredictable stress model of depression in rats. Stereotaxic and polysomnography were used to record the sleep-wakefulness cycle. The behaviour of rats was tested in the open field. RESULTS BCEF0083 increased ambulation and rearing score of chronic unpredictable stressed rats in the open field. BCEF0083 attenuated REMS percent and latency in chronic stressed rats obviously. CONCLUSION BCEF0083 can ameliate sleep-wakefulness cycle and behaviour in chronic unpredictable stress model of depression in rats.

ObjectiveTo study the efficacy and safety of heated humidified high flow nasal cannula ( HHHFNC) and nasal continuous positive airway pressure( NCPAP) ventilation for prevention of extubation failure in extremely low birth weight(ELBW)infants in our NICU.MethodsFrom Jan.2011 to Dec. 2014, 129 ELBW infants admitted to our hospital were randomly assigned into HHHFNC group and NCPAP group. The inclusion criteria were gestational age ( GA ) <34 w, birth weight ( BW )<1000 g, admission within 7 d after birth and transition to noninvasive respiratory support after a period of mechanical ventilation with an endotracheal tube. The primary outcome included:the incidence of extubation failure, nasal injury, air leak, abdominal distention and bronchopulmonary dysplasia ( BPD). Results Statistically significant difference sexisted between the two groups on oxygen the rapyduration, the time required reaching total enteral feedings and the incidences of nasal injury, air leak, abdominal & nbsp;distention and necrotizing enterocolitis ( P<0. 05). The incidence of extubation failure within 7 days was 25. 8℅ in HHHFNC group and 47. 6℅ in NCPAP group ( P <0. 05 ) . No differences between the 2 groups on total ventilation duration, non-invasive ventilation duration, re-intubation rate at 3d after extubation, BPD, retinopathy of prematurity ( ROP ) , intracerebral hemorrhage ( ICH ) , periventricular leukomalacia(PVL)and patent ductus arteriosus(PDA).Conclusions HHHFNC is an effective and safe method for prevention of extubation failure in ELBW infants.

Objective To investigate the effects of early nasal intermittent positive pressure ventilation (NIPPV) compared with early continuous positive airway pressure (NCPAP) in low birth weight preterm infants with respiratory distress syndrome (RDS).Methods We performed a prospective,randomized controlled trial involving 364 low birth weight preterm infants with respiratory distress syndrome within 6 hours of birth.The infants were randomly assigned to NIPPV (n=188) or NCPAP (n=176) groups.Non invasive ventilation was initiated in the neonatal intensive care unit (NICU).The rate of mechanical intubation (within 3 days or 7 days),the use of pulmonary surfactant (PS),the rate of complications and mortality were compared between the two groups.Mann Whitney U,t and Chi-square tests were used for statistical analysis.Results The average time of invasive mechanical ventilation in NIPPV group were lower than that in NCPAP group[2.0 (1.0-4.0) d vs 7.0 (3.0-8.5) d,U=-3.457,P=0.001].The need for intubation and mechanical ventilation by day 3 and day 7 in the NIPPV group were less than those in the NCPAP group [day 3:4.8％ (9/188) vs 10.8％ (19/176),x2=4.621,P=0.032; day 7:9.0％ (17/188) vs 16.5％ (29/176),x2=4.551,P=0.033].In the NIPPV group,infants who got PS therapy was less than that in the NCPAP group [3.2％ (6/188) vs 8.5％ (15/176),x2=4.752,P=0.029].There was no significant difference in the fatality rate between the NIPPV and the NCPAP group [12.8％ (24/188) vs 10.8％ (19/176),P ＞ 0.05].There were no significant difference in the incidence of air leak,intracranial hemorrhage,periventricular leukomalacia,retinopathy of prematurity,necrotizing enterocolitis,patent ductus arteriosus,and bronchopulmonary dysplasia between the NIPPV group and the NCPAP group.Conclusion Among low birth weight prcterm infants with RDS,the early use of NIPPV reduces the need for PS,intubation and invasive ventilation compared with NCPAP.

Objective To investigate the expression and the possible clinical significance of serum Golgi protein(GP73)in infantile hepatitis syndrome(IHS)by different causes.Methods Totally 79 patients with IHS in Guangzhou Women and Children's Medical Center from February 2012 to December 2012 were enrolled in this study,including 15 cases with biliary atresia(BA)group,29 cases with infection(infection group),5 cases with neonatal intrahepatic cholestasis caused by citrin deficiency(NICCD group),and 30 cases with unknown etiology(idiopathic infantile hepatitis group).At the same time,30 healthy infants were enrolled as healthy control group.The serum levels of GP73 were determined by quantitative enzyme-linked immunosorbent assay(ELISA),and the children's liver function[alanine aminotransferase(ALT),aspartate aminotransferase(AST),total bilirubin(TBIL),direct bilirubin(DBIL),alkaline phosphatase(ALP),γ-glutamyl trans-peptidase(γ-GT),total bile acid(TBA)and albumin(ALB)] were measured by turbidimetric inhibition immuno assay.Then,the corresponding data were statistically analyzed.Results Serum GP73 in BA group,infection group,NICCD group,idiopathic infantile hepatitis group and the healthy control group were(296.6±67.5)μg/L,(185.1±66.4)μg/L,(199.2±87.1)μg/L,(181.7±74.2)μg/L and(65.3±17.0)μg/L,respectively.Serum γ-GT levels in BA group,infection group,NICCD group,idiopathic infantile hepatitis group and healthy control group were(764.7±775.8)U/L,(448.2±352.7)U/L,(239.4±88.7)U/L,(283.3±377.2)U/L and(54.0±72.6)U/L,respectively.The levels of GP73 and γ-GT were significantly higher in infants with IHS,and the levels of GP73 and γ-GT in infants with BA were the highest(F=46.775,9.238,all P<0.05).There was a positive correlation between serum levels of GP73 and γ-GT(r=0.280,P<0.05),and there was no correlation between GP73 and ALT,AST,TBIL,DBIL,ALP,TBA,ALB(r=-0.061,-0.071,0.164,0.123,0.137,0.008,-0.047,respectively,all P>0.05).The receiver operating characteristic curve(ROC)constructed with GP73 showed a sensitivity of 80.0％and specificity of 82.8％with an area under the receiver(AUC)of 0.872 for diagnosis of BA,comparatively,a sensitivity of 66.7％and specificity of 71.9％were showed with a AUC of 0.731 when performed with γ-GT.Conclusions Serum GP73 concentration significantly increased in all liver disease groups,regardless of the etiology.Serum GP73 expression is significantly higher in infants with BA.Serum GP73 shows a superior sensitivity and specificity to γ-GT for diagnosis of BA,which might be useful for early diagnosis of BA and IHS with different causes.

To discuss clinical diagnosis and treatment of cow’s milk protein allergy and cow’s milk protein-induced FPIES (food protein induced enterocolitis syndrome). Methods We retrospectively analyzed clinical data of one infant with milk protein allergy-induced FPIES. Results A 67 days old female on mixed breast and formula feeding developed recurrent diarrhea, abdominal distension, vomiting, mucousy and bloody stools, feeding dififculty, anemia, and failure to thrive since 2 weeks after birth. Laboratory studies showed anemia, increased CRP level and elevation of peripheral white blood count and eosinophil proportion. Milk-speciifc IgE was negative. She was previously hospitalized 4 times, all with admitting diagnosis of“necrotizing enterocolitis”. We treated her with milk protein elimination for 4 weeks and all symptoms were resolved. Milk protein re-challenge test was positive, consistent with clinical features of cow’s milk protein allergy-induced infant FPIES. Conclusions Cow’s milk protein allergy and cow’s milk protein-induced FPIES can present with non-speciifc and variable clinical symptoms and signs, and should be considered in the differential diagnosis.

OBJECTIVETo observe the protective effect and mechanism of Fufang Tangshang Gao (FFTSG) on deep grade II burn wounds in rats.

METHODThe deep grade II skin burn model was established. FFTSG was adopted for wounds once everyday for 21 d. Samples were collected at different time points after burn to determine the wound healing rate, the wound tissues water content, VEGF, TNF-alpha and IL-1.

RESULTAt different time points, FFTSG (0.4, 0.2, 0.1 g x g(-1)) could increase the wound healing rate and VEGF content and decrease the tissues water content, TNF-alpha and IL-1.

CONCLUSIONFFTSG shows a notable protective effect on deep grade II burn wounds in rats by obviously promoting the wound healing and decreasing the wound tissues water content. Its mechanisms may be related with the increase in VEGF synthesis and release of wound tissues and the decrease in TNF-alpha and IL-1 in rat blood serum.

The data of a child with sphingosine phosphate lyase insufficiency syndrome (SPLIS) admitted to Children′s Hospital of Hebei Province on February 4, 2020 were retrospectively analyzed.The child had edema, complicated with ichthyosis, adrenal calcification, and hearing loss from the early infancy.Laboratory examination results suggested a low albumin level, hypercholesterolemia, a high proteinuria level, abnormal liver and renal functions, and hyponatremia.The child gave up treatment and died at home.Whole Exome Sequencing (WES) results showed two hete-rozygous mutations of SGPL1 gene (chr10: 72604336, c.134G>A, p.W45X; chr10: 72629563, c.719G>T, p.S240I). SPLIS is inherited in an autosomal recessive manner.It starts in infancy, and affects the kidney, skin, endocrine, nervous and immune systems.It is suggested that SPLIS patients should take genetic examination.Early diagnosis, appropriate intervention, and vitamin B 6 treatment may relieve some symptoms of SPLIS patients.Adeno-associated virus mediated SGPL1 gene replacement therapy can be a novel cure of SPLIS and is worthy of investigation.
