Objective To explore the expression of antiapoptotic gene Aven in childhood acute lymphoblastic leukemia (ALL) and its relationship with clinical features of ALL. Methods Reverse transcriptase polymerase chain reaction (RT-PCR) was used to detect the expression of Aven mRNA in 55 cases of childhood ALL The control group included 11 childhood patients with no malignant hematological diseases. Results Aven mRNA expression was found to be higher in patients ≥10 years old and was also significantly higher in relapsed patients. Univariate and multivariate analysis indicated that Aven overexpression was an independent poor prognostic factor. Conclusion Aven mRNA expression is abnormal in childhood ALL and is an independent poor prognostic factor.

Objective To investigate whether sex,age-of-onset,education and asymmetry affect non-motor symptoms (NMS)in Parkinson disease,and to analyze the relationship between motor symptoms and NMS in Parkinson's disease.Methods The detailed clinical information of 157 patients with idiopathic Parkinson's disease(PD)was recorded and followed up.The data was calculated with SPSS statistic software.Sex had an impact on sleeping disorder (P＜ 0.05).Sleep disorder in female was more prominent.Cognitive disorder was affected by age-of-onset and education duration.The pain and sensory disorder were affected by age-of-onset (P ＜ 0.05).Differences in the effects of asymmetry on NMS were not statistically significant (P＞ 0.05).The higher the scores of postural instability and gait difficulty (PIGD)were,the lower the Mini-Mental State Examination (MMSE)score was(β=-1.837,P =0.004).The higher the tremor score was,the higher the Hamilton Depression Scale(HAMD) score was(β=3.460,P =0.001).The higher the rigidity akinesia score was,the higher the autonomic dysfunction score was(β=0.104,P=0.006).Conclusions The non-motor symptoms of Parkinson's disease are affected by the age,sex and cultural level.Symmetryor-not does not affect Parkinson's disease.Non-motor symptoms and motor symptoms are closely linked.The encountered posture and gait abnormalities of patients should trigger physician alerts to focus on patients' cognitive function.The encountered tremor of patients should trigger physician alerts to focus on their emotional changes.Facing to the patient with rigidity and less moving,physician should alert to the occurrence of autonomic symptoms.

The first research on the NS1 protein as the non-structural protein of the type A influenza virus was emphasized on the considering of its depressant effect on the composition of the protein of host cell.And now,with deep research,the evolution of its genes and the antigenicity of its protein have been explained.The NS1 protein of influenza virus has the association with the apoptosis induced by the influenza virus,the regulating function of apoptosis has the direct correlation with possibility of producing interference and the cell line infected by influenza virus.The NS1 protein restrained to producing the interferon by infected cell.The NS1 protein plays an important role on the host anti-viral cytokine responses,it possesses nagitive regulation for interferon's antiviral activity,most observation indicated nagitive regulation might associate with the virulence of influenza virus.Furthermore NS1 protein as an inspection antigen to differentiate and diagnose the poultry which was immunized or naturally infected has a very wide prospect,because the traditional vaccine was used extensively.

Objective:To understand the monitoring levels of individual dose to radiation workers in Jiangsu province from 2011 to 2018, and to analyze their changing trends.Methods:Through National Individual Dose Registry, the data on the monitoring result of occupational external exposure of radiation workers in our province was collected, and statistical analysis was performed.Results:A total of 176 134 radiation workers in Jiangsu province were collected from 2011 to 2018. The annual collective effective dose was 58 man·Sv and the average annual effective dose was 0.35 mSv. The average annual effective doses to medical radiation workers for interventional radiology and nuclear medicine were both 0.41 mSv, with significantly higher NRE ratios than others ( χ2=219.1, P<0.05). By 2018, the numbers of monitored workers were 25 714 for medical radiation, accounting for 81%, with an average annual effective dose of 0.24 mSv, and 6 169 for industrial radiation, accounting for 19%, with an average annual effective dose of 0.18 mSv. Conclusions:The average annual effective dose to radiation workers in Jiangsu province is in consistency with the relevant national standards. The dose values for radiation workers in interventional and nuclear medicine are relatively high. The protection measures in their workplace should be improved. Meanwhile oversight of radiation protection should be enhanced for individual radiation workers in Jiangsu province.

Objective To investigate the clinical features and genetic mutations of spinocerebellar ataxia type 17 (SCA17).Methods The pathological CAG triplet repeat expansions of the SCA3,SCA1,SCA2,SCA6,SCA7,SCA8,SCA12,SCA17 and dentatorubral pallidoluysian atrophy genes were analyzed in 708 probands of autosomal dominant familial SCA and 1 19 sporadic SCA cases.The CAG repeats of TATA-binding protein (TBP) gene were amplified by means of polymerase chain reaction and agarose gel electrophoresis.For the samples with two alleles,fragment analysis based on CEQ8000 sequencer was applied to analyze the CAG repeat numbers.Furthermore,the correlation between clinical features and CAG repeat in the TBP gene was studied carefully.Results The expanded CAG repeats in the TBP gene was detected in 5 cases with 37/50,36/45,38/52,38/53,36/54 separately.And the main clinical manifestations were ataxia and memory impairment.Conclusion These findings indicate that SCA17 might be a rare subtype of SCA in the Chinese population and the clinical features of SCA17 cover a wider spectrum than previously reviewed.

BACKGROUND: As for the treatment of chylous fistula concurrent in oral-maxillofacial tumor resection simultaneously undergoing neck lymph node dissection, many different approaches have been put forward. A simple surgical ligation, strong negative pressure drainage, filling the muscle tissue alone or a combination of the above methods are all unsatisfactory regarding the prognosis and curative effect.OBJECTIVE: To evaluate the validity of medical biological adhesive cohering peripheral autologous muscle tissues to block thoracic duct fistula in order to prevent chylous fistula following neck lymph node dissection.METHODS: All of the 12 patients were detected and diagnosed as chylous fistula in neck lymph node dissection surgery, the wounds were immediately sutured and treated with medical biological adhesive cohering peripheral autologous muscle tissues to block thoracic duct fistula. RESULTS AND CONCLUTION: Of all the 12 patients, 10 recovered without chylous fistula or severe complications, and reoperations were adopted to cure the failed 2 cases. All patients were visited 3 months postoperatively, no recurrence of chylous fistula, local stimulus response or allergy was found. It is suggested medical adhesive to block thoracic duct fistula may be an effective and safe way for prevent chylous fistula following neck lymph node dissection.

Objective To investigate the relationship between glucose excursion and cognitive function in aged type 2 diabetes. Methods A total of 248 aged type 2 diabetes were recruited in this study,all of them wore continuous glucose monitoring system (CGMS) for 3 d to evaluate the glucose excursion including mean amplitude of glycemic excursions (MAGE) which was used for assessing intra-day glycemia variability,and mean daily difference (MODD) which represented day-to-day glycemic variability.During the period of CGMS monitoring,all subjects accepted mini mental status examination (MMSE) for evaluating cognitive function.The relationships of MAGE and MODD with performance on cognitive tests were assessed. Results The over intra-day glucose excursion group had lower MMSE score than the narrow intra-day glucose excursion group[(24.25±6.75)vs.(25.97±0.47),P=0.025].The MMSE score was decreased in over day-to-day glucose excursion group compared with the narrow day-to-day glucose excursion group [(24.21 ± 6.47) vs. (26.01 ± 5.49),P =0.019]. A statistically significant association was observed between MAGE and the score of MMSE(r=- 0.308,P＜0.001),and between MODD and MMSE(r=-0.226,P =0.001).Conclusions Glucose excursion may affect cognitive function in aged type 2 diabetes.The over glucose excursion decreases the score of MMSE.
