ABSTRACT
Objective@#To understand the etiological characteristics of hand, foot and mouth diseases (HFMD) in Dezhou city from 2010 to 2018, and to provide laboratory evidence for its prevention and control.@*Methods@#A total of 5 186 fecal specimens were collected from patients with HFMD. Real-time RT-PCR was used to detect enterovirus (EV) and analyze its pathogenic characteristics.@*Results@#From 2010 to 2018, 5 186 samples of HFMD cases were detected in Dezhou, with a total positive rate of 71.75%, including 1 357 cases of EV-A71 (26.17%), 874 cases of CV-A16 (16.85%) and 1 490 cases of other Enteroviruses (28.73%). There were significant differences in the overall detection rate in each month. The peak period of detection rate was from June to August. The dominant virus strains with different types appeared dynamically in different years. EV-A71 was the predominant serotype in severe and aggregated cases. Laboratory confirmed cases were mainly children under 5 years old (96.25%).@*Conclusions@#From 2010 to 2018, the pathogen of HFMD in Dezhou city showed a dynamic change, with obvious seasonal distribution of cases and high incidence of specific population. Etiological surveillance should be strengthened to focus on prevention and control of high-risk population in high-risk season.
ABSTRACT
Objective@#To understand the epidemiologic features of the rabies in Xishuang banna prefecture of Yunnan province, China in 2008-2017 and the viral molecular-evolution characteristics.@*Methods@#The data of rabies case questionnaire were collected. The brain tissue samples from mad dogs, suspicious sick dogs and human brain tissue, saliva and cerebrospinal fluid samples from rabies patients were collected in Xishuangbanna. Coding region of nucleoprotein and glycoprotein genes were amplified by RT-PCR and sequenced. Homology and phylogenetic analysis were performed using the relevant bioinformatics software.@*Results@#A total of 62 cases of human rabies were occurred in 28 districts of the 3 counties, Xishuangbanna prefecture in 2008-2017. Of them, 37 cases in Jinghong county, 15 in Menghai county and 10 in Mengla county. In which 48 cases were bitten by domestic dogs (77.42%), 11 cases were bitten by wild dogs (17.74%). Rabies case was occurred every year in the past decade. The seasonal incidence was not obvious. The majority of patients were aged from 30 to 59 years-old, with the youngest 1 year-old and the eldest 91 year-old. The male to female ratio was 1.70∶1, most cases were farmers. The nucleotide sequences of nucleoprotein gene of 9 virus strains (7 from Jinghong, 1 from Menghai and 1 from Mengla) were obtained from the samples of dogs and patients. Homology and phylogenetic analyses indicated that the 5 strains belonged to clade China-Ⅰ, 3 clade China-Ⅱ and 1 clade China-Ⅵ. The nucleotide sequences of glycoprotein gene of 5 virus strains (3 from Jinghong, 1 from Menghai and 1 from Mengla) were obtained from these positive samples, and all were clade China-Ⅰ, it is same with nucleoprotein genes analysis result from these 5 virus strains. These China-Ⅰ and China-Ⅱ strains from Xishuangbanna have a closer genetic relationship with same clade strains isolated from Pu’er and other prefectures of Yunnan province as well as Sichuan, Guizhou and Guangxi. The China-Ⅵ strain from Xishuangbanna share high homology and genetic relationship with China-Ⅵ strains isolated from southwestern Yunnan and neighbouring countries such as Myanmar, Laos and Vietnam in recent years.@*Conclusions@#In Xishuangbanna, rabies mainly occurred in rural area and domestic dog was the main source of transmission. These RABV clades China-Ⅰ, China-Ⅱ and China-Ⅵ were found in this region and the China-Ⅰ was principal clade. The transmission source of China-Ⅰ and China-Ⅱ were from adjacent areas in the province and China-Ⅵ was from Myanmar and Laos.
ABSTRACT
Objective@#To illustrate the epidemical characteristics of the dog-biting events and molecular evolution of rabies virus (RV) strains prevalent in Shuangbai county of Yunnan province, China.@*Methods@#Epidemical investigation on the dog-biting events and human cases were conducted and the brain tissues of the biting dogs and human cases were sampled post-mortem. Nucleoprotein (N) genes of the RVs were sequenced. Homology and phylogenetic analysis were performed using the relevant bioinformatics software.@*Results@#A total of 12 dog-biting events took place between 2011-2017 in Shuangbai county and 35 persons were bitten. Of the 12 events, 11 were investigated in time and 32 bitten persons received proper wound management and a full post-exposure vaccination course. Rabies has not developed in these wounded cases until now. However, due to failure to receive medical intervention and post-exposure treatment in time, 1 of 3 bitten persons in a single event died of rabies. RV N genes from 5 dogs and 1 person were sequenced. Phylogenetic tree showed that RV strains prevalent in Shuangbai county were closely related with the ones found in neighboring counties/cities such as Chuxiong, Lufeng, Jingdong and Xiangyun. All these strains were related to the ones denoted as clade China-I and prevalent in Sichuan province. Homology analysis showed 99.6%-100% homology in nucleotide and amino acid among the 6 RVs prevalent in Shuangbai county and those prevalent in Chuxiong, Lufeng, Xiangyun and clade China-I of Sichuan province. Compared with the China-I strains prevalent in Chuxiong, Zhaotong and Qujing prefectures between 2006-2007, the homology of nucleotide and amino acid were 97.1%-99.3% and 99.1%-99.6%, respectively.@*Conclusions@#Surveillance on the dog-biting events can prevent rabies in humans effectively. RV strains prevalent in Shuangbai county belong to clade China-I and have a close relationship with those of neighboring prefectures, cities, counties and the ones prevalent in Sichuan province.

ABSTRACT
Objective@#To understand the molecular evolution characteristics of the nucleoprotein (N) genes and epidemiological feature of 118 rabies virus (RABV) strains isolated in Yunnan province, China from 2006 to 2015.@*Methods@#The brain tissue samples from mad dogs, suspicious sick dogs, sick cow, and human brain tissue, saliva and CSF samples from rabies patients were collected in Yunnan province to detect the viral antigen by direct immunofluorescence assay (DFA). The viral RNA from positive samples was extracted. Coding region of N gene was amplified by RT-PCR and sequenced. The phylogenetic tree was constructed by Neighbor-Joining method of MEGA5.0 software.@*Results@#The sequences of N genes of 91 RABV strains in Yunnan from 2012 to 2015 were obtained. With the sequences of N genes of 27 RABV strains in Yunnan from 2006 to 2011 and 29 RABV strains from Southeast Asian Countries, the phylogenetic analysis was performed. RABV strains in Yunnan were divided into clades YN-A (105 strains), YN-B (6 strains), YN-C (7 strains), which belonged to clades China-I, China-VI, China-II respectively. Clade YN-A was epidemic every year from 2006 to 2015, of them, 14 strains from 2006 to 2011 and 91 strains from 2012 to 2015 were distributed in 13 prefectures (cities) of Yunnan. Clades YN-B and YN-C were epidemic only from 2006 to 2010 and from 2008 to 2011 respectively. The regional distribution of clades YN-B and YN-C was limited. The strains of YN-A and YN-C were closely related to the strains of clades China-I and China-II from neighboring Sichuan, Guizhou, Guangxi and Hunan provinces. The strains of YN-B were closely related to the strains from Myanmar, Laos, Vietnam and Cambodia.@*Conclusions@#Three RABV clades with multiple transmission sources were identified in Yunnan. Clade YN-A was widely distributed in rabies endemic area in Yunnan from 2006 to 2015, and it has strong ability to spread as principal clade in Yunnan. Since 2012, clades YN-B and YN-C were not found again in Yunnan.
ABSTRACT
Objective To investigate if Carroll Upper Extremities Functional Test (UEFT) is a better rating scale for evaluating fine mo-tor function in children with cerebral palsy. Methods From January, 2011 to January, 2014, 104 children with cerebral palsy were divided in-to non-hemiplegic palsy group (n=76) and hemiplegic palsy group (n=28), they were assessed by two certified valuers in one week. Their fine motor function was evaluated with UEFT and the Gesell Developmental Scale. The scores of UEFT were compared respectively with the developmental age (DA) and developmental quotient (DQ) in fine motor domain of Gesell Developmental Scale. At the same time, the UEFT score of the affected limb was compared with of the unaffected limb in children with hemiplegic palsy. Results In the non-hemiplegic palsy group, the UEFT score strongly correlated with DA (r=0.752, P0.05). The UEFT score of unaffected limb was significantly higher than that of the affected limb (Z=-4.708, P<0.001). Conclusion Both of UEFT and the Ge-sell Developmental Scale could be used clinically in assessment of fine motor function in children with cerebral palsy. The UEFT was better in evaluating children with hemiplegic palsy.

ABSTRACT
We wished to sequence the full-length genomes of the DHL10M110 strain of the Akabane virus (AKV) isolated from mosquitoes in Yunnan Province, China, in 2010. We also wished to analyze the characteristics of these complete nucleotide sequences. The complete genomic sequence of the DHL10M110 strain from Yunnan Province was obtained by reverse transcription-polymerase chain reaction and direct sequencing. We found that the length of the L, M and S gene nucleotide sequences of the DHL10M110 strain were 6 869-bp, 4 309-bp and 856-bp, respectively, including the open reading frame (ORF) nucleotide sequences of 6 756-bp (L), 4 206-bp (M) and 702-bp (S), encoding 2252, 1402 and 234 amino-acid polyproteins, respectively. Phylogenetic analyses based on L-fragment ORF showed that the DHL10M110 strain had a close relationship with the OBE-1 strain of the AKV from Japan and AKVS-7/SKR/2010 strain of the AKV from South Korea. Phylogenetic analyses based on M- and S-fragment ORF showed that the DHL10M110 strain had a close relationship with the epidemic strains of the AKV from Japan, South Korea and Taiwan, but that the DHL10M110 strain had a lone evolutionary branch. In terms of nucleotide (amino acid) homology, the similarity of L-, M- and S-fragment ORFs of the DHL10M110 strain to the OBE-1 strain from Japan was 92.6% (98%), 88.5% (94%) and 96.4% (99.1%), respectively. When comparing the DHL10M110 strain with the OBE-1 strain, we noted 45, 84, and 2 different sites in the amino acids of L, M and S fragments, respectively. Homology and phylogenetic analyses also suggested that the DHL10M110 strain had a distant relationship with the epidemic strains of the AKV from Kenya and Australia. Also, we confirmed by complete genomic sequence analyses that the DHL10M110 strain was clade-Asia of the AKV. However, differences between the DHL10M110 strain compared with strains from Japan and South Korea were also noted. These results suggest that the DHL10M110 strain harbored relatively stable genetic characteristics and distinct regional features. This is the first time that full-length genomic sequences of the DHL10M110 strain of the AKV in mainland China have been obtained.

Objective To detect thyroid hormone receptors (TRs) mRNA expression of subjects exposed to different levels of arsenic,to further study the endocrine disturbing effect of arsenic.Methods Molecular epidemiological method was used,in drinking water type of endemic arsenic poisoning areas,which were divided into control (＜ 10 μg/L),low (10-＜ 100 μg/L),medium (100-＜ 200 μg/L) and high (≥200 μg/L) dose groups based on the drinking water arsenic concentrations.According to the gender stratification,a total of 273 (control,low,medium and high dose groups were 58,49,66,100,respectively) residents were chosen.To carry out the questionnaire,urine arsenic determination,electrocardiographic examination.Real-time PCR was used to detect blood TRs mRNA expression.Results TRα mRNA relative expression levels in the control,low,medium and high dose groups were (12.2 ± 5.7) × 10-4,(12.2 ± 5.0) × 10-4,(12.3 ± 5.4) × 10-4,(12.2 ± 4.3) × 10-4,respectively,the differences were not statistically significant (F =0.109,P ＞ 0.05).TRβ mRNA relative expression levels were all low,the control,low,medium and high dose groups were (5.7 ± 4.1) × 10-6,(8.6 ± 7.6) × 10-6,(6.3 ± 4.2) × 10-6 and (6.2 ± 3.8) ×10~,respectively,the differences were statistically significant (F =2.938,P ＜ 0.05).The levels of TRβ mRNA relative expression changed with increased content of arsenic in water and urine trends in inverse U-shaped curves (R2 =0.035,0.067,all P ＜ 0.05).TRβ mRNA relative expression in low dose group was higher than that in control group,the difference was statistically significant (P ＜ 0.05);TRβ mRNA relative expression in high dose group was lower than that in low dose group,the difference was statistically significant (P ＜ 0.05).Arsenic induced arrhythmia which most displayed sinus bradycardia;the prevalence of arrhythmia in the control,low,medium and high dose groups were 12.1％ (7/58),10.2％ (5/49),13.6％ (9/66),19.4％ (19/98),respectively,the differences were not statistically significant (x2 =2.877,P＞ 0.05).Heart rate was positively associated with the level of TRβ mRNA relative expression in lg value (r =0.218,P ＜ 0.05).Conclusion Chronic arsenic exposure can disturb TRβ mRNA expression;there is a possible relationship between TRβ mRNA abnormal expression and arrhythmia caused by arsenic.
ABSTRACT
To evaluate the prevalence of mosquito-borne viruses in Manshi and Ruili (Yunnan Province, China), we collected 2 149 mosquitoes (17 species) in August 2010. Virus isolation was undertaken by the cul- ture of baby hamster kidney cells (BHK-21 cells). Two virus-like isolates were obtained: DHL10M117 was isolated from collected in Mangshi; DHL10M110 was obtained from Anopheles vagus collected in Rui- li. Both isolates caused cytopathic effects,illness and death in suckling mice inoculated with these isolates via the intracerebral route. Two positive amplicons, 702-bp from the S segment and 456-bp from the M segment,were obtained using reverse transcription-polymerase chain reaction using primers specific for the Akabane virus (AKV). Phylogenetic analysis suggested that these two virus stains had a distant relation- ship with AKVs from Kenya and Australia,but were genetically close to those from Japan,South Korea, and Taiwan. However,they were separate from other Asian strains and grouped into a small branch. The highest nucleotide and amino-acid sequence identity of the S segment was found with the CY-77 strain from Taiwan (96.6% and 99.6% for DHL10M117 and 96.7% and 100% for DHL10M110,respectively). Com- parison of the M segment showed they shared the highest amino acid identity with CY-77 (99.6% and 100%, respectively), whereas the highest nucleotide identity was found with the Iriki strain from Japan (99.6% and 100%, respectively). Compared with the MP496 strain from Kenya,they displayed lower lev- els of sequence homology, at 69.7% and 70.0% for nucleotide sequences of the two loci,and 91. 0% for a- mino acids. Our results identified that DHL10M117 and DHL10M110 were strains of AKV,and provided molecular biological evidence for the existence of AKV in Yunnan Province. These AKV strains that are circulating in Yunnan Province share a close genetic relationship with strains from the rest of Asia. Culex tritaeniorhynchus and Anopheles vagus may serve as transmission vectors.

ABSTRACT
This paper aimed to research on return visit and investigation of the relapse rate of children allergic purpura after treatment. Children with allergic purpura were divided into two groups. The treatment group was treated with the adrenocorticotrophic hormone while the control group did not. We tracked and observed two groups of discharged children in the first month and the second month. It can be found that, at the first month, 5 cases recurred in the treatment group with 20 cases, the relapse rate was 25%, 1 case recurred in control group, the relapse rate was 5%; at the second month, 2 cases recurred in treatment group, the relapse rate was 10%, no case recurred in the control group. There were 8 cases recurred in the past two months, and there were no replase after the second time treatment. In contrast, the children, who treated with adrenocorticotrophic hormone, had higher relapse rate, while the control group had lower relapse rate. Then we can get the conclusion that, the application of adrenocorticotrophic hormone may be one of the main reasons to induce the allergic purpura and we should notice and discuss this conclusion in the clinical practice

Conclusion Cx. tritaeriorhynchus had been the major species of mosquitoes and mainly transmitting vector of mosquito-borne viruses in Dehong prefecture. GenotypeⅠJEV,GETV and CppDNV were the vectors causing transmission of mosquitoe-borne diseases in this area. Data from phylogenetic analysis showed that these newly discovered isolates seemed to have had close relationship with those viruses previously circulating in Yunnan and other provinces of China.
ABSTRACT
Objective To investigate the distribution patterns of mosquitoes and mosquito-borne viruses in Dehong prefecture,Yunnan province,China. Methods Mosquito samples were collected using the mosquito traps from five counties of Dehong prefecture on July,2007 and 2010. Mosquitoes were cell cultured for viral isolation,and positive isolates were identified using RT-PCR and sequence analysis. Results A total of 43 634 mosquitoes comprised of 29 species representing six genera were collected. Culex tritaeriorhynchus and Anopheles sinensis comprised 78.69% and 14.77% of the total. Six strains of viruses were isolated from the mosquito pools. RT-PCR and phylogenetic analysis revealed three strains from Cx. tritaeriorhynchus,identified as genotypeⅠJapanese encephalitis virus(JEV). One strain was identified from Cx. tritaeriorhynchus,as Getah virus (GETV). Two strains isolated from Cx. tritaeriorhynchus and Anopheles vagus were identified as Culex pipiens pallens Densovirus(CppDNV). Conclusion Cx. tritaeriorhynchus had been the major species of mosquitoes and mainly transmitting vector of mosquito-borne viruses in Dehong prefecture. GenotypeⅠJEV,GETV and CppDNV were the vectors causing transmission of mosquitoe-borne diseases in this area. Data from phylogenetic analysis showed that these newly discovered isolates seemed to have had close relationship with those viruses previously circulating in Yunnan and other provinces of China.
ABSTRACT
Objective To investigate the therapy effect of deanxit combined with large dose of oryzanol in the treatment of post stroke depression(PSD) and anxiety in elderly male.Methods Sixty cases of PSD and anxiety patients were divided into three groups by random number table method with 20 cases in each,deanxit group treated with deanxit,oryzanol group treated with oryzanol,and combination group treated with deanxit and large dose of oryzanol,a total of 4 weeks.Before and after 4 weeks treatment respectively using Hamilton depression scale (HAMD) and Hamilton anxiety scale (HAMA) scores.Results The HAMD and HAMA scores before treatment in three groups had no statistical significance (P ＞ 0.05).Compared with before treatment,HAMD and HAMA scores in three groups after treatment were significantly lower (P＜ 0.01).HAMD scores in combination group were improved better than those in deanxit group and oryzanol group [(12.85 ± 3.69) scores vs.(15.30 ± 3.28),(18.65 ± 3.13) scores](P＜ 0.01),and deanxit group were better than oryzanol group(P＜ 0.01).HAMA scores in deanxit group and combination group were lower than those in oryzanol group [(8.65 ± 3.33),(7.25 ± 3.34) scores vs.(10.65 ± 3.18) scores] (P ＜0.01).Conclusion Deanxit combined with oryzanol is effective in the treatment of PSD and anxiety in elderly male.
