Objective To construct an immortalized rat astrocyte strain expressing enkephalin which can be regulated by doxycycline.Methods pRevTet-On and recombinant plasmid pRevTRE/hPPE were transfected into packaging cell PT67 respectively by standard lipofectamine methods.The supernatant containing RevTet-On virus was used to infect immortalized rat astrocyte strain(IAST)and RevTRE/hPPE virus was used to infect the IAST/Tet-On cell.Immortalized rat astrocyte strain that stably expressed Tet-regulated enkephalin was established. hPPE gene expression level of IAST/Tet-On/hPPE cell strain was detected by real time-PCR,immuno- cytochemistry and radio-immunoassay.Results Real time-PCR,immuno-cytochemistry and radio-immunoassay confirmed the level of enkephalin expression was regulated by doxycycline in a dose-dependent manner.Conclusion An immortalized rat astrocyte strain which secrets enkephalin as controlled by doxycycline has been constructed successfully.

Aim To investigate the changes of cerebral blood flow in rats with diabetic cognitive impairment by two-channel laser Doppler flowmeter,and to explore the changes of cerebral blood flow in diabetic rats with cognitive impairment and to investigate the changes of cerebral blood flow lesions and the central nervous system function changes in the study to provide pre-foundation.Methods Thirty-four male Wistar rats were randomly divided into two groups:blank control group and diabetic model group.The rats in the model group were treated with streptozotocin (STZ) 60 mg · kg-1,and the glucose oxidase method was used to determine fasting blood glucose ≥ 16.7 mmol · L-1 as the standard of the model.The Water maze was used to observe the behavioral changes of diabetic rats.Dual-channel laser doppler flowmeter was used to measure cerebral blood flow in diabetic rats with cognitive impairment.Another 34 male Wistar rats were randomly divided into two groups:control group and diabetic model group.Dual-channel laser doppler flowmeter was used to dynamically monitor cerebral blood flow on 0 d,7 d,14 d,21 d,28 d,35 d,42 d,56 d and 75 d.ELISA was applied to detect the concentration of iNOS,eNOS and ET-1 in cerebrospinal fluid.Results Morris water maze test showed that the time of the platform (latency) was significantly longer than that of the blank control group(P ＜0.05).The cerebral blood flow/100 g of diabetic rats with cognitive impairment was significantly lower than that of the control group (P ＜ O.05),and the blood flow in the model group was significantly lower than that in the model group (P ＜ 0.05).Compared with control group,iNOS and eNOS concentrations were markedly elevated,while ET-1 concentration obviously decreased.Conclusions The decrease of blood flow in the frontal cortex of diabetic rats with cognitive impairment suggests that it may be one of the factors leading to cognitive impairment in diabetes mellitus.Cerebral blood flow reduction occurs in the early stages of diabetes,followed by no significant deterioration.Cerebral blood flow may not be related to the changes of NO and ET-1,but the trend of cerebral blood flow may be related to the change of the two.

Objective To evaluate the relationship between carotid atherosclerotic plaques stability and the clinical symptoms of carotid atherosclerosis by contrast-enhanced ultrasonography. Methods Fifty patients with carotid atherosclerotic plaques were examed with contrast-enhanced ultrasonography,the contrast agent visualization of the carotid atherosclerotic plques were analyzed and compared with their clinical symptoms. Results Twenty-three patients who suffered from obvious clinical symptom were entirely visualized. Twenty-weven patients had not apparent clinical symptom,of these patients,15 were sparse visualized,there was no visualization in other 12 patients. Conclusions Conlrast enhanced ultrasonography can real-time observe microcirculation in carotid atherosclerotic piques,and assess the stability of carotid atherosclerotic plaques.

This study was aimed to evaluate the relationship between carotid atherosclerotic plaque stability and the clinical symptoms in patients with carotid atherosclerotic plaques by using contrast-enhanced ultrasonography. Fifty patients with carotid atherosclerotic plaques were enrolled and examined with contrast-enhanced ultrasonography. The correlation of contrast agent enhancement of the carotid atherosclerotic plaques and the clinical symptoms was analyzed. The results showed that among the 50 patients, plaques were enhanced in the 23 patients with obvious clinical symptoms. In 27 patients without apparent clinical symptoms, plaques were enhanced sparsely in 15 patients and not enhanced in 12 patients. It was suggested that contrast-enhanced ultrasonography could be used for the examination of the microcirculation in carotid atherosclerotic plaques on real-time basis and serve as a new noninvasive approach for the assessment of stability of carotid atherosclerotic plaques.

Objective To study the ultrasonic features and outcomes of VACTERL association fetuses. Methods From Jan 2003 to Sep 2013 in Shenzhen Maternity&Child Healthcare Hospital there were 55 fetuses diagnosed as VACTERL association, the prenatal ultrasonographic characteristics and outcomes were summarized. Results Ultrasonography showed that the incidence of 6 VACTERL association anomalies were:vertebral defects were 45.5%(25/55), anal atresia were 30.9%(46/55), cardiac malformations were 81.8%(45/55), tracheoesophageal ifstula/esophageal atresia were 32.7%(18/55), renal anomalies were 60.0%(33/55) and limb anomalies were 83.6%(17/55). All the 55 fetuses had 3 or more VACTERL association malformations and the characteristic ultrasonic features were as follows:(1) There were 39 cases (70.9%, 39/55) co-occur with three VACTERL malformations, the more common malformations were limb anomalies (33/39), cardiac malformations (31/39) and renal anomalies (21/39). (2) There were 13 cases (23.6%, 13/55) co-occur with four VACTERL malformations, the more common malformations were cardiac malformations (11/13), limb anomalies(10/13), renal anomalies (9/13) and tracheoesophageal ifstula/esophageal (8/13). (3) There were 3 cases (5.5%, 3/55) co-occur with ifve VACTERL malformations, they were all with anal atresia, cardiac malformations, renal anomalies and limb anomalies (3/3), and two were co-occur with vertebral defects (2/3). (4) No fetus co-occur with six VACTERL malformations. There were 29 cases (52.7%, 29/55) co-occur with other malformations, of which 21 cases (38.2%, 21/55) with single umbilical artery. All the 55 cases underwent labor induction. The results of postmortem appearance of 55 cases and autopsies of 9 cases were all consistent with prenatal ultrasound scan. Conclusions Fetuses with VACTERL association had characteristic prenatal ultrasound imaging, multiple malformations can be found and limb anomalies, cardiac malformations and renal anomalies are more common. Scanning the fetal structures from higher incidence to lower incidence of VACTERL association can be helpful to improve the diagnostic coincidence rate of VACTERL association. Prenatal ultrasound diagnosis of VACTERL association can provide guidance for clinical obstetrical management.

Objective To summarize and analyze prenatal ultrasound and postnatal autopsy ifndings in fetuses with urorectal septum malformation sequence (URSMS). Methods An analysis of prenatal ultrsound ifndings and postnatal autopsy features was performed on eleven cases of fetuses with URSMS that were identiifed by ultrasonography at Shenzhen Maternity&Child Healthcare Hospital in the period of January 2003 to December 2012. Results Prenatal ultrasonography showed a large abdominal cystic mass concomitant with imperforate anus in eleven fetuses with URSMS. The cyst contained unilocular or bilocular cystic structures in two fetuses, and trilocular cystic structures in nine fetuses. The cyst was demonstrated as clear acoustic transmission in three fetuses and unclear in eight fetuses. Out of them, seven fetuses had kidney abnormalities, six had ascites, and three had enterolithiasis. The associated systemic abnormalities included tethered cord in two fetuses, single umbilical artery in two fetuses, sacrococcygeal dysplasia in one fetus, and myocardial noncompaction in one fetus. 21-trisomy was found in one fetus by chromosome examination. Eleven cases were all identiifed as female fetuses by autopsy ifndings, including a single perineal opening and ambiguous genitalia with clitoral hypertrophy and labial fusion. The internal genital abnormalities included double vagina or longitudinal vaginal septum in nine fetuses, double uterus or uterus bicornis in ten fetuses and vaginal dysplasia in one fetus. Conclusions URSMS is a complex congenital malformation, which includes abnormalities of the urinary system, reproductive system and gastrointestinal track. An abdominal cystic mass visualized by prenatal ultrasonography might be the distinctive lesion in female with URSMS, and have an important diagnostic value. The kidney abnormalities and ambiguous genitalia can contribute to the diagnosis of URSMS.

ObjectiveTo summarize prenatal ultrasound image features of Cantrell′s syndrome (Cantrell′s pentalogy).MethodsFrom January 2007 to December 2013 in Shenzhen Maternity & Child Healthcare Hospital, there were twenty cases diagnosed and conifrmed by postmortem as Cantrell′s syndrome. The prenatal ultrasound image features and outcomes were analyzed.ResultsAmong the twenty cases, eighteen were singleton and two were twins with the other normal fetus. Prenatal ultrasound image: two obvious ultrasound image features of ectopic heart and hight omphalocele (seventeen cases) or gastroschisis (three cases) were appeared in prenatal ultrasound of twenty cases. Fourteen cases were complete ectopic heart (Ectopic heart was located within the omphalocele in one case, ectopic heart was completely exposed in amniotic lfuid in thirteen cases), six cases were incomplete ectopic heart, three cases were ventricular septal defect in which one was associated with pulmonary stenosis, two cases were single atrium and single ventricle in which one was associated with a single arterial trunk, one case was tetralogy of Fallot, and six cases were without signiifcant heart abnormalities. Associated with other abnormalities: seventeen cases were associated with other abnormalities in twenty cases, in which eleven cases were spinal abnormalities, nine cases were umbilical cord abnormalities (short umbilical cord in six cases, single umbilical artery in two cases, short umbilical cord associated with single umbilical artery in one case), ifve cases were neurological abnormalities (exencephalia in four cases, encephalocele in one case), four cases were limb abnormalities, three cases were cheilopalatognathus, one case was giant bladder. Three cases weren′t associated with other abnormalities. Nuchal Translucency: in eight cases, nuchal translucency were measured in early pregnancy. Nuchal translucency of ifve cases were thick, one case was cervical hygroma in one of the two twins. Chromosome examination results: only three cases had chromosome examination in twenty cases, in which one case was trisomy 21, another two were chromosome normal. Fetal outcome and examination results: in twenty cases, one of the two twins can′t survive after birth, and the other one of two twins was reduced in intrauterine, so the specimen could not be obtained. Eighteen cases of singleton underwent labor induction. The results of postmortem appearance (nineteen cases) and autopsies (ifve cases) were all consistent with prenatal ultrasound scan.ConclusionsEctopic heart and hight omphalocele or gastroschisis appearing at the same time was the characteristic of Cantrell′s syndrome in prenatal ultrasound and other abnormalities may be part of the Cantrell′s syndrome spectrum. It is beneift to detect and diagnose Cantrell′s syndrome by prenatal ultrasound in the ifrst trimester.

Objective To explore the distribution rule of metastatic lymph node in nasopharyngeal carcinoma (NPC) by magnetic resonance imaging (MRI).Methods 315 histopathologically proved NPC patients were studied retrospectively.All patients had had their nasopharynx scanned by MRI with plain and contrast enhanced sequences.The distribution of lymph node was divided into six cervical levels plus retro- pharyngeal nodes(RN) according to RTOG guidelines proposed in 2003.Results 254 out of 315 patients (80.6%) had lymph node involvement,with 81 in the right neck alone,72 left neck alone,and 101 both necks;73 in RN alone,21 neck node alone,and 160 both necks and RN node.Skip metastasis was found in only 4 patients (1.6%).There was significant difference in BN metastasis between the primary tumor be- ing located merely on the superior/posterior wall and lateral wall (78% vs 49%,P＜0.01).The incidence of lymph node metastasis in T1,T2,T3 and T4 patients was 73.5%,91.2%,71.9%,73.5% (P＞0.05), respectively,without significant difference between early or advanced T stage in node distribution (P＞0.05).Conclusions The incidence of lymph node metastasis is high in nasopharyngeal carcinoma,with retropharyngeal node being the most commonly involved,but the incidence of skip metastasis is very low. There is no significant difference between T stage and the incidence of lymph node metastasis.So is the dis- tribution of metastatic node.

0.05)and the TNM staging (P=0.55).A mild elevated compared other pathological classification was found in small cell lung cancer (0.191?0.275).Conclusions The results showed that RFQ-PCR was suitable for measurement of the mRNA level of PLKI in bronchoscopic bioptic specimens.This study suggest elevated expression of PLK1 might play a important role in development of lung cancer,so that PLK1 might be a potential tumor marker for Lung cancers.Advanced studies will be needed to clarify that PLKI mRNA level do not relate to TNM staging and pathological classification.
