Objectives Inborn errors of metabolism (IEM) has a diverse spectrum and different incidence in different countries, the early diagnosis at presymptomatic stage is imperative to benefic patient from sequelae. Phenylke-tonuria (PKU) / hyperphenylalaninemia (HPA) is the most common metabolism disorder in Shanghai as well as in other regions. The study is to further clarify the incidence of inborn errors of metabolism among newborn in Shanghai. Methods The dried blood spot specimens were collected from near 90 local maternity and children's hospitals or general hospitals in Shanghai. PKU/HPA screening was carried out by fluorometric method. Neonatal screening using tandem mass spectrometry was performed in one of the study centers, Xinhua neonatal screening center. Results A total of 815 160 cases were screened from 2001 - 2007 in Shanghai, the incidence of PKU/HPA was 1 : 12 351. The tetrahydrobiopterin deficiency was 12.9% among hyperphenylalaninemia patients. According to the 116 000 neonatal samples data detected by tandem mass spectrometry, 20 cases were confirmed diagnosis, including 6 kinds diseases, it was PKU/HPA, maple syrup urine disease, methylmalonicacidemia, propionic acidemia, 3-methylcrotonyl-CoA carboxylase defection, and short chain aeyl-CoA dehydrogenase deficiency. Conclusions The pilot study shown that inborn errors of metabolism neonatal screen-ing using tandem mass was 1 : 5 800 in Shanghai, PKU/HPA was the most common disease. It is expected that the expansion of newborn screening using tandem mass spectrometry could be further considered and further improving inborn errors of metabolism preventive services in Shanghai.

Objective To identify a suspected Klebsiella variicola strain isolated from a patient with severe septic shock. Methods Sequences of rpoB, gyrA, mdh, infB, phoE and nifH genes were obtained from the clinical isolated suspected Klebsiella variicola strain, and used for constructing phylogenectic trees. Characteristics of phylogenetic trees were used to distinguish Klebsiella variicola from Klebsiella pneumoniae. Results All target gene sequences from this clinical isolated strain constantly formed a cluster with their counterparts from other Klebsiella variicola strains. These clusters were readily differentiated from Klebsiella pneumoniae clusters. Conclusions The clinical isolated strain belongs to Klebsiella variicola class and can cause septic shock. From genetic perspective, Klebsiella variicola is distinctly different from Klebsiella pneumoniae, most of which can be isolated from normal healthy people.

Objective To understand the level of neonatal pain knowledge and attitudes of neonatal and obstetric department nurses, in order to supply the clinical basis for neonatal pain management. Methods Self-designed questionnaires to fill out on-site were distributed to 107 neonatal and obstetric department nurses (of which 40 were from neonatal department, 67 from obstetric department) for neonatal pain knowledge and attitudes. Results About question of neonatal pain, the average percentage of correct answers in the neonatal group was 75.5%, higher than 66.3% of the obstetric group, in the neonatal group, correct rate of seven questions was more than 80%,while in the obstetric group the correct rate of only one question was more than 80%, and 5 questions correct response rate was significantly lower than that of the neonatal group, the difference was significant. All nursing staff considered it essential or necessary to carry out the nursing knowledge of pain-related training. 95.0%(38/40) of neonatal nurses believed that they could properly assess the extent of neonatal pain, but only 83.6% (56/67) for the obstetric group, the difference between the two groups was significant. 97.5% (39/40) of neonatal nurses believed that they could make the right judgments on neonatal crying, and only 85.1%( 57/67) in the obstetric nurses, the difference between the two groups was significant.Conclusions Neonatal pain has gradually been recognized and paid attention to by the clinical front-line medical staff, they believe that it is necessary to receive training on neonatal pain, knowledge of neonatal pain of neonatal nurses is better than obstetric nurses.

Results 94 cases of 160 were diagnosed as abnormal, including 50 stenosis or obstructive disease, 21 aneurysm, 1 post-intravascular stent, 4 cliped aneurysm, 3 arteriovenous malformation, 4 moyamoya disease, 4 carotid-cavernous fistula, 4 venous sinus thrombus, 1 straight sinus occlusion with perpetual falcial sinus, 1 great cerebral venous aneurysm, 1 perpetual sublingual artery. Conclusion 64-slice spiral CTA is a valuable diagnostic method for various cerebral vascular disease.

Objective To establish a monitoring database of historical Oncomelania hupensis environments at grass?root lev?el for schistosomiasis prevention based on Google Earth(GE),so as to improve the management efficiency of historical O. hu?pensis environments. Methods GE was labeled with the information about the historical O. hupensis environments through add?ing landmark,path and polygon. Meanwhile,POCO web album was used to storage the practice situation pictures of the environ?ments,which could be imported into GE so that the environments could be monitored dynamically. Results There were 553 historical O. hupensis snail environments in Yangjian Town,Xishan District,Wuxi City and the accumulative area was 506 000 m2. Among these environments,224(40.5%)were Class IV environments,accounting for 40.5%of accumulative area. Conclu?sions The monitoring database of historical O. hupensis environments based on GE at country level is established successfully and it can be used to manage the historical snail environments visually and monitor the changes dynamically.

Objective To investigate the role of individual dental stent on taste protection in the patients with primary nasopharyngeal carcinoma.Methods Firstly,dosimetric evaluation of the tongue under the circumstance of 10 pairs of patient wearing dental stent or not was done.Secondly,a total of 61 patients were randomized into two arms:29 were in the trial arm and 32 in the control arm.The patients wore dental stent during radiotherapy in trial group,but not in control group.The endpoint was taste dysfunction before radiotherapy,every week during radiotherapy till the completion of radiotherapy,and followed up six months after radiotherapy.Results The mean dose of tip of tongue,body of tongue,base of tongue for patient with dental stent or not were (394.43±24.01) cGy,(986.35±77.15) cGy,(4 401.16±179.01) cGy and (677.03± 110.05) cGy,(2 418.19±414.18) cGy,(4 878.67±387.45) cGy (P value were 0.031,0.007 and 0.284,respectively) separately.By the completion of the radiotherapy,there were 9 (31.03 ％) patients suffering from a taste dysfunction in the trial group and 25 (78.13 ％) in the control group (P ＜ 0.001).Conclusions Individual dental stent has a potential tendency to relieve the taste impairment by reducing the irradiation dose of tongue.

Objective To investigate the expressions of Nanog and Oct4 (stem cell transcription factors) in endometriosis and adenomyosis, and to explore their potential functions in the development of endometriosis and adenomyosis. Methods The expressions of Nanog and Oct4 in the ectopic and eutopic endometrium of 50 patients with endometriosis and/or adenomyosis (ectopic endometrium group and eutopic endometrium group), and 21 patients free from endometriosis and adenomyosis (control group) were detected by immunohistochemical SABC methods. Statistical analysis was conducted for the correlation between the expressions of Nanog and Oct4 based on patients′ clinical pathological parameters. Results Nanog and Oct4 protein expressions in ectopic endometrium group were higher than that in control group (P<0.01);the expressions of Nanog and Oct4 in eutopic endometrium group and control group showed no significance (P > 0.05); there was positive correlation between the expressions of Nanog and Oct4 in ectopic endometrium group (r = 0.590, P < 0.01). Conclusion Nanog and Oct4 present high expression in eutopic and ectopic endometrium , which may play a important role in the development of endometriosis and adenomyosis.
