Background Mesenchymal stem cells (MSCs) have been applied in basic and clinical researches of organ transplantation.Our previous study showed that intravenous injection of MSCs prolonged corneal allograft survival in rat.However,the effect of local administration of MSCs on corneal allograft rejection remains unclear.Objective The aim of this study was to investigate the effect of subconjunctival injection of MSCs on corneal allograft rejection in rat model of keratoplasty.Methods MSCs were isolated and cultured from femur and tibia bone marrow of clean Wistar rats,and then the cells were identified by induced differentiation of osteoblast and adipocyte.The third generation of MSCs was used in subsequent experiment.Allogenic penetrating keratoplasty was performed with the bilateral corneas of 20 Wistar rats as donor grafts and the right eyes of 40 Lewis rats as recipients.PBS 0.1 ml containing 2 × 106 MSCs and 0.1 ml PBS only was subconjunctivally injected immediately and postoperative 3 days respectively in randomized two groups,and another 6 normal Lewis rats served as the normal control group.Corneal rejection response was evaluated under the slit lamp after surgery based corneal opacity,edema and neovascularization,and the grafts were scored according to the criteria of Larkin.The corneal samples were extracted from 12 rats of the PBS control group and the MSCs group separately 10 days after surgery.The relative expressions of Th1 cytokines (interferon-γ [IFN-γ] mRNA and interleukin-2 [IL-2] mRNA) and Th2 cytokines (IL-4 mRNA and IL-10 mRNA) were detected by real-time quantitative PCR.Protein levels of IL-4 and IL-10 proteins in the corneas were assayed by ELISA.All experimental protocols involving rats were approved by the laboratory animal care and use committee of the Tianjin Medical University and treated with the ARVO statement for the use of animals in ophthalmic and vision research.Results The cells grew well with the orange stain for alizarin red in differentiated the osteoblasts and red stain for Oil red O in differentiated adipocytes.The survival time of corneal graft in the MSCs group was (11.8±1.6) days,it was significantly longer than (9.6±1.4) days in the PBS control group (P=0.004).The levels of IL-4 mRNA and IL-10 mRNA in the MSCs group were significantly higher than those in the PBS control group (both at P =0.00);while the levels of IFN-γ mRNA and IL-2 mRNA were not significantly different between the groups (both at P＞0.05).The IL-10 protein contents were (22.74 ±7.06),(68.40±12.83) and (215.41 ±44.66)pg/ml in the normal control group,PBS control group and MSCs group,showing significant difference among the three groups (F =55.06,P =0.00) and a significant increase in the MSCs group compared with the PBS control group and the normal control group (both at P ＜ 0.05).Conclusions Subconjunctival injection of MSCs prolongs the survival time of cornea allograft in penetrating keratoplasty probably by modulating the balance between Th1 and Th2 cytokines,especially by up-regulating Th2 cytokines.

Objectives To assess the performance of first trimester ultrasound screening for fetal structural and chromosomal anomalies based on a detailed anomaly and nuchal translucency (NT) scan at 11-13+6 weeks' gestation.Methods A prospective cohort study was conducted at Nanjing Drum Tower Hospital.Fetuses with a crown-rump length (CRL) between 45 mm and 84 mm scanned during December 2015 to March 2016 were enrolled in this study.After a detailed first-trimester anomaly scan followed the protocol of systematic standardized scan plans,fetuses with congenital abnormalities were screened out.Second trimester ultrasound screening and postnatal examination were performed for further examination of fetal anomalies.Cytogenetic analysis was performed on the fetuses with informed consent.Results (1) A total of 1 154 fetuses were enrolled in this study and among them,36 (3.1％) cases of fetal abnormalities were diagnosed through prenatal examination (35 cases) and postnatal examination (one case).(2) Twenty-one (58.3％) out of the 36 cases with structural and chromosomal anomalies were screened out by using the first-trimester scan,including eight cases of congenital cardiac defect (two cases of atrioventricular septal defect,one case of tricuspid atresia,one case of tetralogy of tetralogy,one case of right ventricle aneurysms and one cases of hypoplastic left heart syndrome combined with cystic hygroma with one case combined with polydactyly),four cases of central nervous system anomaly (three cases of exencephaly and one case of anencephaly combined with double outlet right ventricle),two cases of cleft palate/lip with one case combined with double outlet right ventricle,two cases of exomphalos,one case of amniotic band syndrome,one case of spinal bifida combined with megacystis,one case of umbilical cyst,one case of polydactyly and one case of cystic hygroma.One case of twin pregnancy chose selective fetocide to the fetus with exencephaly and 16 cases terminated pregnancy.The other four cases were confirmed by second trimester ultrasound screening and postnatal examination.Fourteen (38.9％,14/36) new cases of structural and chromosomal anomalies were detected by the second-trimester scan,six of which terminated the pregnancies and the rest were confirmed at term.One (2.8％,1/36) case of polydactyly was detected postnatally.(3) Chromosomal microarray analysis was performed on 28 cases,seven of which were identified as having chromosomal abnormalities including five cases detected in the first trimester and two cases detected in the second trimester.(4) Out of the 20 fetuses with abnormal NT in early trimester,which accounted for 1.7％ of all enrolled fetuses,nine were indentified with major structural or chromosomal abnormalies,a quarter of all abnormal fetus.Conclusions Detailed anomaly scan and NT scan in the first-trimester can increase the detection rate of fetal structural and chromosomal anomalies as compared with the traditional NT scan and provide earlier detection of severe fetal abnormalities as compared with second trimester anomaly scan.

Objective To investigate the expression of homeobox gene MSX-2 during cranial suture fusion of SD rats and discuss its significance. Methods SD rats aged 1, 2, 5, 8, 12, 15, 18, 22, 30 and 45 days were selected, and immunohistochemistry and Real-time PCR were employed to localize and quantify the expression of MSX-2 in different regions of cranial sutures. Results MSX-2 expressed in calvarial suture tissues including the extreme ends of the osteogenic fronts and the underlying dura mater. The expression of MSX-2 was low in posterior frontal suture (PF) and sagittal suture (SAG) from postnatal day 1 to day 8 before the initiation of suture fusion, while it was higher in PF than in SAG from postnatal day 12 to day 22 after the initiation of PF suture fusion. The expression of MSX-2 significantly declined in PF and was moderately higher than that in SAG from postnatal day 30 to day 45 after the initiation of suture fusion. Conclusion There is different expression of MSX-2 in PF and SAG during different suture fusion periods, which suggests the expression of MSX-2 may participate in the regulation of cranial bone development and the fusion of cranial sutures.

Objective To investgute the effect of lO-Hydrocamptothecin (HCPT) on collagen induced arthritis (CIA) rats, and to explore the potential value of it in the treatment of Rheumatoid arthritis(RA). Methods After the model of CIA was established ,the rats were randomly divided into five groups: control group, CIA model group, MTX treatment group, high dose HCPT treatment group and low dose HCPT treatment group. The synovium was examined with regular HE stain and the apoptosis of synoviocytes was detected with TUNEL All these pathological changes were evaluated. In addition, the change of articular volume was measured,and the serum TNF-α and IL-1β level was also measured at different time point. The results were analyzed by the statistical software SPSS 11.5. Results Comparing to CIA model group, both MTX and HCPT group could improve patients' general condition, alleviate joint swelling, inhibit proliferation of synoviocytes, induce apoptosis of synoviocyte and decrease the plasma level of TNF-α, IL-1β (P<0.05), however, there was no significant difference could be found between the MTX and HCPT group (P>0.05). Conclusion HCPT has the potential value in the treatment of RA.

Objective To investigate the clinical and electroencephalogram (EEG) characteristics of children with electrical status cpilepticus during sleep (ESES), and the response to medication therapy. Methods AEEG and VEEG including an entire sleeping c-ycle were performed on 26 patients with ESES. The clinical and EEG changes, neuropsychological impairment and the response to medication therapy were followed up. Results Twenty five patients had seizures,21 cases had normal psychomotor development before ESES. After the onset of the disease,Fifteen cases developed language disorder, 16 cases developed psychological and behavior abnormalities, 13 cases had both of the problems Seventeen patients belonged to epileptic syndrome. Patients in this cohort had good response to clonazepam and valproate treatment. Cortical steroid could dispel the electrical discharge. Eighteen patients had been followed up. Seizures stopped in 15 cases after treatment ESES disappeared in 16 cases, 4 of them still had neuropsychological impairment ESES sustained in 2 cases Conclusions ESES is a specific EEG phenomenon. Continue epileptic form discharge during non - rapid cye movement sleep is the major cause of neuropsychological impairment in patients with ESES. To control the seizures and electrical state are very important for the prevention and treatment of neuropsychological impairment.
