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 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.

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 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.

OBJECTIVETo observe the regulatory effects of electroacupuncture with different acupoints combinations on blood lipid and atherosclerosis index (AI) in rats with hyperlipemia, so as to make a preliminary screening for the optimal acupoints combination for hyperlipemia.

METHODSOne hundred and five clean-grade SD male rats were randomly divided into 9 groups, including a normal group, a model group, a Quchi group, a Zhongwan group, a Fenglong group, a Quchi+Zhongwan group, a Quchi+Fenglong group, a Zhongwan+Fenglong group and a Quchi+Zhongwan+Fenglong group (three acupoints group), 17 rats in the normal group and 11 rats in the rest groups. The normal group was fed with normal diet, while the rest groups were fed with high-fat diet for 3 weeks to prepare the hyperlipemia model. All the rats were given unlimited water. After the establishment of model, the normal group was fed freely without any treatment; the model group was bundled and immobilized everyday; the rest groups were bundled, immobilized and treated with electroacupuncture at corresponding acupoints with disperse-dense wave, 20 min per time, once a day. After 4 weeks, the blood examples were collected from abdominal aorta to measure the total cholesterol (TC), triglyceride (TG), high-density lipoprotein (HDL-C) and low-density lipoprotein (LDL-C), and analyzed the AI in each group.

RESULTSAfter the treatment, TC, TG, HDL-C, LDL-C and AI in each acupuncture group were all lower than those in the model group (P<0.05, P<0.01). Compared with single acupoint group and the Quchi+Zhongwan group, the content of TC in the three acupoints group was lower (P<0.01). The differences of content of TG among each acupuncture group were not significant (all P>0.05). Compared with the rest 6 acupuncture groups, the content of HDL-C and AI in the three acupoints group were significantly different (all P<0.05). The content of LDL-C in the three acupoints group was decreased as compared with the Quchi group and the Zhong-wan group.

CONCLUSIONThe electroacupuncture at "Quchi" (LI 11), "Zhongwan" (CV 12) and "Fenglong" (ST 40) has more advantages on regulating the content of HDL-C and LDL-C as well as improving AI in hyperlipemia rats, and it has superior effects on blood lipid metabolism.
