BACKGROUND: Child neglect is one of the most important aspects of child abuse and has become a serious problem influencing children's development all over the world. Therefore, it is necessary to nderstand the current conditions and influential factors of child neglect and establish effective evaluation methods in China.OBJECTIVE: To investigate the current conditions and influential factors of urban child neglect in Suzhou city.DESIGN: A comparative analysis of sampling survey.SETTING: Department of Children's Health Care, Soochow University Affiliated Children's Hospital.PARTICIPANTS: This study was conducted in one public kindergarten and two private kindergartens of urban areas in Suzhou city between March and October 2003. Totally 370 children (196 boys and 174 girls) aged between 4 to 6 years old without obvious physical and mental diseases were voluntarily investigated, and they had been living with the person that answered the questionnaire regarding to child neglect in China in the recent 1 year. METHODS: Questionnaire regarding to child neglect in China was sent to each volunteer.he questionnaire evaluates the current conditions of child neglect by 20 items of 5 aspects including physical care (buy fruit for child, consider the nutritional need of child, care about the body height and body mass of child), emotional care (chat with child, play and tour with child, encourage child to do the things whatever they can, listen to what the child feels, introduce the child to the guests when they come to your home, let him or her stop immediately when child cries, care about the activities in kindergarten), education care (buy books for child, tell stories to child, recognize and correct the bad behavior of child, answer the questions asked by child seriously), safety care (protections against fire and electricity at home, warn child against matches, knives and other sharp things, teach child how to cross the road) and health care (prepare the common medicine for child at home, urge child to brush teeth, correct the bad posture). The volunteers were asked to answer each question objectively according to the conditions of child within the recent 1 year, and each question should be answered by selecting only one choice (never, occasionally, usually, always), and anyone should not be omitted. Meanwhile,the educational background and occupation of the parents were also investigated.MAIN OUTCOME MEASURES: The general status of child neglect and the effects of different family educational background and occupation of parents on child neglect were observed. RESULTS: Totally 370 questionnaires were sent out, and 370 qualified ones were recollected, the effective rate was 100%. ① In Suzhou city, the children were given better regards and good care in the aspects of education, medicine and safety, but neglects on children's physical and mental care still exists in a few families. ② Families of different educational background could think highly of the medical care, safety and psychical care of children, but neglects on education and emotional development more commonly existed in the families with the educational background under university. ③ All the families with different occupation could think highly of the medical care, safety and physical care of the children, but education and emotional development were better in the cadre families than in the ordinary families.CONCLUSION: In Suzhou city, the children are given better regards and good care in the aspects of education, medicine and safety, but some bad manifestations of child neglect exist in education and emotion, which are associated with the educational background and occupation of the parents.Further studies about the evaluation, prevention and intervention are needed for child neglect in China.

Objective:To analyze the clinical phenotypes and prenatal diagnosis of a pedigree with oculo-facio-cardio-dental (OFCD) syndrome.Methods:A pregnant woman at 17 gestational weeks was admitted to the Nanjing Drum Tower Hospital, the Affiliated Hospital of Nanjing University Medical School in 2017 for genetic counseling. Genetic tests as performed for the proband (the pregnant woman), her husband, and the induced fetus of last pregnancy genetic test and the detected variants were analyzed and verified by chromosomal microarray analysis (CMA), multiplex ligation-dependent probe amplification (MLPA) and quantitative real time-polymerase chain reaction (Q-PCR). The detection platform established by MLPA and Q-PCR technology was used to perform prenatal diagnosis of the present pregnancy. Other family members were screened for BCOR gene mutation. Related mutation types were retrieved from ClinVar database with term of " BCOR", and related literature from CNKI and PubMed with terms of "OFCD syndrome", " BCOR gene", and "oculo facio cardiac dental syndrome" to summarize the clinical manifestations, mutation type and pathogenesis of this disease. Results:The proband has congenital cataracts, long face, congenital atrial septal defect, and severe dental malformations, which were consistent with the clinical features of OFCD syndrome. WES suggested that the proband and her induced fetus were suspected of having a large submicroscopic deletion of the exons of BCOR gene, which was confirmed by CMA, MLPA and Q-PCR, with a 105 kb deletion containing BCOR exons 1-15. The amniotic fluid genetic analysis of the present pregnancy showed that the fetus has a normal female karyotype, and did not carry the same BCOR gene copy number abnormality as the proband. The child grew and normally developed without any characteristic manifestations of OFCD syndrome during follow-up. Other families of the proband did not show clinical features of OFCD syndrone, and no BCOR gene copy number abnormality was detected. A total of 35 cases of BCOR gene mutation types related to OFCD syndrome were retrieved from ClinVar database. The data analysis revealed that the differences in clinical manifestations between Lenz microphthalmos syndrome and OFCD syndrome were mainly caused by different mutation types of BCOR gene. Among the 90 retrieved cases of OFCD syndrome obtained through literature, only one case was reported in China. Analysis of these 90 cases showed that the characteristic manifestations of OFCD syndrome, involving the eye, face, heart, teeth, and skeletal system. OFCD syndrome were confirmed in the proband and her induced fetus according to the clinical manifestation and the mutation type of BCOR gene. Conclusions:The clinical manifestations of OFCD syndrome are complicated, caused by various mutation types of BCOR. Systematic molecular genetic technology can be effectively applied for gene and prenatal diagnosis of OFCD syndrome.

Objective To investigate the effect of calcium antagonist verapamil on the function of rat?- cells and tolbutamide (D860)-induced insulin release.Methods Insulin released from isolated islets were measured in control,verapamil,D860,and verapamil+D860 groups.Furthermore,intravenous glucose tolerance test (IVGTT) was conducted in acute experiments treated with verapamil and D860 respectively to assess?-cell function in rats with the same allocation as in vitro.Another IVGTT was performed in the end of 4 weeks' treatment.The insulin contents in pancreas were assayed and pancreas islets morphology were observed with immunohistochemistry.Results Verapamil could inhibit insulin release from isolated islets.Verapamil group was [(1.244?0.082)ng?ml~(-1)?islet~(-1)]and control group (2.623?0.226) ng?ml~(-1)?islet~(-1)(P0.05).Also,similar results were obtained in normal rats during acute experiments and verapamil reduce the hypoglycemic effect promoted by D860. However,above results were not observed in the end of 4 weeks experiments,and no difference for insulin content and morphological change in islets was found among four groups.Conclusion Treatment of verapamil chronically does not impair islet function and interfere with the hypoglycemic effect of D860 in rats .

Aim ToinvestigatetheeffectsofCa2+/calmodulin-dependent protein kinase Ⅱ inhibitor KN-93 on calcium overload-induced heart injury.Methods Thirty-twoisolatedratheartswererandomlydivided into the control group,KN-93 control group,calcium paradox group,and calcium paradox with KN-93 treat-ment group.Left ventricular pressure were recorded, and the heart function was evaluated by the left ventric-ular end-diastolic pressure (LVEDP ) and developed pressure (LVDP).Coronary flow (CF)were collect-ed,and lactate dehydrogenase (LDH)content was de-termined.Triphenyltetrazolium chloride staining was usedtomeasuretheinfarctsize.Results Compared with the control group,KN-93 at 2. 5 μmol·L-1 had no effects on coronary flow,cardiac performance and cell death at the end of perfusion in normal rats (P>0. 05 );The hearts of calcium paradox exhibited a de-crease in LVDP and CF,meanwhile an increase in LV-EDP,LDH,and infarct size of 18 ±7. 2% (P <0. 01).2. 5 μmol·L-1 KN-93 further increased the levels of LVEDP,LDH and infarct size (P<0. 01)in Ca2+paradoxical hearts,while it provoked the decline intheCFandLVDP(P<0.01).Conclusion The data demonstrates that KN-93 aggravates heart injury in calcium paradox,it also suggests that CaMKⅡ is in-volved in the Ca2+overload-induced heart injury.

Objective To analyze the histological changes of bone diseases and to investigate the noninvasive measurements for diagnosing renal osteodystrophy (ROD) in maintenance dialysis patients . Methods Ninety-one patients were selected to receive bone biopsy . The bone samples were stained with HE, toluidine blue and Masson, and were examined with light microscopy . The levels of immunoreactive parathyroid hormone (iPTH), osteoprotegerin (OPG),sRANKL and osteocalcin (OCN) were determined in the patients enrolled from 2004 to 2006 . The level of iPTH was measured by radioimmunoassay . OPG and sRANKL were measured by ELISA,and OCN was measured by chemiluminescence . Results The incidence of ROD in the maintenance patients was 100% . According to the histological appearance, 50 cases (54 .9%) were high turnover bone disease (secondary hyperparathyroid bone disease), 9 cases (9 .9%) were low turnover bone diseases(osteomalacia and adynamic bone disease), and 32 cases(35 .2% ) were mixed bone disease . The level of iPTH in patients with ROD was significantly increased compared with healthy controls . It was the lowest in low turnover bone diseases . There was no difference among three types of ROD . OPG level was significantly increased compared with healthy controls [(2176 .58±1576 .08) pmol/L vs (1310 .46±1254 .00) pmol/L, P＜0 .05] . The level in high turnover bone diseases was higher than that of the healthy controls [(2261 .85±1712 .22) pmol/L vs (1310 .46±1254 .00) pmol/L, P＜0 .05] . There was no difference among three types of ROD .sRANKL level in high turnover bone disease was significantly increased compared with healthy controls [(0 .328±0 .524)pmol/L vs (0 .084±0 .190) pmol/L, P＜0 .05] . OCN level was also higher than that of the healthy controls (P＜0 .05), and the OCN level in low turnover ROD was the lowest among three types of ROD . OCN level in mixed ROD was dramatically increased as compared to low turnover ROD [(226 .633±66 .455) pmol/L vs (193 .03±104 .269) pmol/L, P ＜0 .05] .Conclusions The histological changes of bone disease can be indicated by iPTH level, but the types of ROD can not be distinguished according to iPTH level neither be differentiated by the levels of OPG, sRANKL and OCN . Bone histomorphometry is still the golden standard for diagnosing renal osteodystrophy .

Objective To investigate the effect of ifenprodil in the mice of bone cancer pain.Methods 96 male C3H/HeJ mice were divided randomly into tumor group( Group T),control group( Group C) and sham group( Group S).The α-minimal essence media(ct-MEM) with 2 × l05 osteosarcoma NCTC 2472 cells were implanted into the intramedullary space of the right femurs of mice to induce ongoing bone cancer related pain behaviors.The sham group was inoculated by α-MEM without any cells.On the 14th d after inoculation,pain ethology indexes such as the spontaneous lifting behaviors,the paw withdrawal mechanical threshold(PWMT) and the paw withdrawal thermal latency (PWTL)were observed on 1 d before inoculation and on 3 d,5 d,7 d,10 d,14 d,17 d,19 d,23 d after inoculation.Lumbar intumescentia of mice in each group were taken out to investigate the expression level of NR2B western blot after pain behaviors tests at the same time point after intrathecal injection.Results ( 1 ) At day14 after the operation,the obvious increasing of spontaneous lifting behaviors ( ( 12.88 ±1.64) ) and the expression of NR2B (2.12 ±0.13),the significant decreasing of PWMT( (0.39 ±0.17)g) and PWTL( ( 11.59 ± 1.67 ) s ) were observed in group T compared with group S and preoperative base level (P ＜ 0.05 ).(2) At day 17,day 19 and day 23 after the operation,compared with the basal level of dayl4 before administration and group C,the spontaneous lifting behaviors ( (5.13 ± 1.38),(4.70 ± 1.58),(5.64 ± 1.17) ) of group T were obviously decreased,PWMT ( ( 1.10 ± 0.65 ) g,( 0.95 ± 0.56 ) g,( 1.05 ± 0.26 ) g) and PWTL ( ( 15.17 ± 1.27) s,( 15.93 ± 2.18 ) s,( 16.28 ± 1.48 ) s ) were increased,the expression of NR2B ( ( 1.42 ± 0.17),(1.67 ±0.53),(1.14 ±0.79) ) were significantly decreased(P＜0.05).Conclusion Repeated intratheal injection of ifenprodil can efficiently relieve spontaneous lifting behaviors,mechanical hyperalgia and thermal hyperalgia and decrease the expression of lumbar intumescentia NR2B in the mouse model of bone cancer pain.

ObjectiveTo investigate the effect of KN93,a CaMKII inhibitor,on the spinal NR2B expression in the bone cancer pain mouse and its underlying mechanism.MethodsThirty-six male C3IL/IIeJ mice were randomly divided into 3 groups:sham group( S,n =8 ),bone cancer pain group( BP,n =8 ) and KN93 group ( K,n=20).The mouse model of bone cancer pain was established by intra-femur inoculation of osteolytie NCTC 2472 cells in BP and K groups.At 14d post operation,mice in K group received intrathecal injection of 60nmol KN93/5μl in 20％ DMSO and mice in BP group and S group received 20％ DMSD 5μl respectively.Eight mice were selected randomly from each group at (1)d before inoculation,at 1 h before administration and at 1,2,4,24h after administration( T0-5 ) to be measured the paw withdrawal threshold(PWT) stimulated by von Frey filaments.Another 3 mice were sacrificed at the corresponding time point and the spinal cord L3 -5 were obtained for determination of NR2B expression by western blot.ResultsPWT was significantly decreased in group BP( (0.50 ± 0.11 ) g) and K( (0.52 ±0.10)g),except for group K at T3(P＞0.05),and NR2B cxpression up-regulated at T2-5 in BP( 1.78± 0.34),K groups ( ( 1.11 ± 0.14),(0.73 ± 0.03 ),( 1.11 ± 0.15 ),( 1.89 ± 0.32 ) ) compared with S group ( ( 1.78 ± 0.31 ) g,(0.33 ± 0.04),P ＜ 0.05 ).Compared with group BP,PWT was increased and NR2B expression down-regulated at T2-4 in group K.In contrast to T1,PWT at T2-4 upgraded in group K(P＜0.05 ),but no significant difference was observed in other groups (P＞ 0.05 ).ConclusionIntrathecal injection of KN93 can attenuate bone cancer pain in mice through inhibiting NR2B with a time-dependent manner and spinal CaMKII-NR2B pathway may participate in the development of bone cancer pain.
