MircoRNAs (miRNAs) are widely existing inorganisms, non-coding small RNA. MircoR-NAs play important role in cell proliferation, apoptosis, stress resistance and fat metabolism. In vitro studies indicate that miRNAs are important factors in platinum resistance of ovarian cancer cell lines. However, the pathway of platinum resistance of ovarian cancers is complex. Studies find miRNA expression play important roles in the sensitivity of platinum resistance of ovarian cancer cell lines , and can be used as an early alert for platinum resistance. Changing the expression of miRNA even can reverse the platinum resistance . But the regular role of miRNAs in target genes network is still unconfirmed. Thus, more studies about miRNA in vivo and animal tumor models are needed to identify the function of miRNAs in platinum resistance of ovarian cancer.

Objective To assess the ability of the new software SonoAVC to measure follicular volume and to compare these volume calculations with those made by conventional methods. Methods Three-dimensional ultrasound imaging was used to acquire volumetric data from the ovaries of 50 women undergoing controlled ovarian stimulation as part of in-vitro fertilization treatment. SonoAVC was used to automatically measure the volume of follicles and virtual organ computer-aided analysis(VOCAL) was also applied to measure volume, which was used as the standard of volume measurement. And the three perpendicular diameters (xyz diameters) of follicles were manually measured by conventional two-dimensional(2D) ultrasound, which were used to estimate volume using the sphere formula. And the validity of each technique was compared using limits of agreement. Results One hundred and seventy-six follicles were studied. SonoAVC and VOCAL provided highly accurate and repeatable follicular volume measurements in all cases. Volumes estimated from manually derived follicular diameter measurements were less accurate and repeatable. VOCAL took more time in follicular volume of measurement than SonoAVC and conventional 2D displays. Conclusions SonoAVC provides highly accurate, repeatable,and efficient measurements of follicular volume.

Objective To investigate the clinical characteristics of digestive system cancer during pregnancy and its influence on mother and fetus.Methods Clinical data of 12 pregnant women accompanied with digestive system cancer obtained from the follow-up record of cancer patients between July 2007 and January 2016 in Daqiao Community Health Service Center of Yangpu District,Shanghai,were retrospectively analyzed.Results Delayed treatment,missed diagnosis and misdiagnosis were found in ten of the 12 cases.Eleven cases underwent B-type ultrasound as an early imaging screening method.Eleven patients had advanced cancer,but only two of them were eligible for radical surgery.Five patients could be treated with anti-tumor therapy.Eleven of the 12 patients died within two years after diagnosis,and only one survived over five years.Eight of the twelve embryos or fetuses died and four neonates survived.Conclusions Digestive system cancer during pregnancy has an insidious onset,and the rates of missed diagnosis and misdiagnosis are high,with advanced disease stage at diagnosis and poor prognosis.Knowledge of the digestive system cancer during pregnancy and early diagnosis and treatment capacity should be enhanced so as to reduce the damage to both the pregnant woman and fetus.

Objective To investigate the difference between contrast sensitivity,noise and crowding phenomenon in normal and ametropic amblyopia children. Design Prospective case series. Participants 50 normal children and 50 ametropic amblyopia children. Method Using the noise visual acuity test chart,crowded visual acuity chart and contrast sensitivity visual chart of the visual perception system developed by the National Medical Care Apparatus Engineering Research Center,normal and ametropic amblyopia children were examined in Beijing Tongren Hospital. Main Outcome Measures The number and the constituent ratio of normal and abnormal children in contrast sensitivity,noise and crowding phenomenon. Results The abnormal results of contrast sensitivity in ametropic amblyopia children and normal children were 60 eyes (60%) and 15 eyes (15%) respectively; the abnormal result of noise visual acuity were 62 eyes (62%) and 30 eyes (30%) respectively; the crowded visual acuity were 56 eyes (56%) and 0 eye respectively (all P=0.000). In mild,moderate and severe ametropic amblyopia children,the abnormal results of contrast sensitivity were 32 eyes (51.61%),20 eyes (66.67%) and 8 eyes (100%) respectively (P=0.005),the abnormal results of crowding phenomenon were 30 eyes (48.39%),18 eyes (60%) and 8 eyes (100%) respectively (P=0.010),the abnormal results of noise were 39 eyes (69.90%),18 eyes (60.00%) and 5 eyes (62.5%) respectively (P=0.868). In mild,moderate and severe refractive error children,the abnormal results of contract sensitivity were 33 eyes (70.21%),9 eyes (34.12%) and 17 eyes (62.96%) respectively (P=0.011),the abnormal results of noise were 30 eyes (63.83%),15 eyes (57.69%) and 17 eyes (62.96%) respectively (P=0.868),the abnormal results of crowding phenomenon were 30 eyes (63.83%),11 eyes (42.31%) and 17 eyes (62.96%) respectively (P=0.172). Conclusion Contrast sensitivity,noise and crowding phenomenon in visual perception tests can be used to estimate the impairment of visual perception in amblyopia children.

By using a highly sensitive HRP-TMB method, the present study found parasympathetic preganglionic neurons innervating rat stomach originated from the dorsal motor nucleus of the vagus(DMV), ambiguus nucleus(AM), reticular formation between DMV and AM(RF). rostroventrolateral reticular nucleus (RVL), lateral parvocelluler reticular nucleus (LRP), paraependymal nucloeus of the vagus (PEV), intercalated nucleus(IC) and retroambiguus nucleus(RA). There was a specific representation area of the stomach in the DMV between 0.3-0.6mm rostral to obex, and the different parts of the stomach had topographical organization within this area. The lateral portion of the DMV mainly innervated the forestomach, the medial and medial-middled portion of the DMV predominantly projected to the antrum/pylorus and corpus, respectively. The right and the left DMV did not show difference in innervating the forestomach and antrum/pylorus, but the corpus was mainly innervated by the right DMV. RF only projected to the forestomach and the corpus. RVL and RA only innervated the forestomach. AM, PEV and IC innervated all the three parts. The relationship between the different neuronal types of the DMV and the different parts of the stomach was first discussed in this paper. The forestomach, corpus and antrum/pylorus received their inputs mainly from the large and small neurons, respectively. The dentrites of the DMV contacting CSF were confirmed.
