Objective To explore the effect of action observation therapy (AOT) on upper limb function in children with spastic hemiplegic cerebral palsy,and the better program. Methods From March to November,2017,45 children with spastic hemiplegic cerebral palsy were randomly assigned to control group and AOT group.The control group was further divided into group A(n=11)and group B(n=11), and received conventional rehabilitation treatment and scenic-observation therapy, 20 minutes every time for group A,and 30 minutes every time for group B.AOT group was further divided into group C(n=10)and group D (n=11), and received AOT in addition, 20 minutes every time for group C, and 30 minutes every time for group D,five times each week for twelve weeks for all the groups.Before treatment,eight and twelve weeks af-ter treatment, they were assessed with hand grip strength, Upper Extremities Functions Test (UEFT), and Wee Functional Independence Measure(WeeFIM). Results After treatment,the hand grip strength and the score of UEFT were better in group D than in groups B and C(P<0.05),and were better at twelve weeks than at eight weeks(P<0.05).No significant difference was found in the score of WeeFIM among groups after treatment(P>0.05). Conclusion AOT could improve upper limp function in children with spastic hemiplegic cerebral palsy,and it's more ef-fective after more training.

OBJECTIVETo investigate the effect of ClpE on the protein expression profiles of Streptococcus pneumoniae.

METHODSclpE-deficient Streptococcus pneumoniae strain was constructed by long flanking homology-polymerase chain reaction (LFH-PCR) and identified by PCR and sequencing. The total bacterial proteins were analyzed by two-dimensional gel electrophoresis and imaging analysis, and the differentially expressed protein spots were excised by dot-gel digestion with trypsin. Peptide mass fingerprinting (PMF) was obtained by analysis of the fragment length by matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF-MS). The PMF was analyzed using software to identify the proteins.

RESULTSThe number of matched protein spots of the two gels was 61%. By sequence database searching, 4 out of the 17 differential protein spots were identified, namely hypoxanthine-guanine, pyrrolidone-carboxylate peptidase1, formate-tetrahydrofolate ligase, and bifunctional protein pyrR.

CONCLUSIONclpE gene-deficient Streptococcus pneumoniae expresses fewer kinds of proteins at also lower levels than the wild-type bacteria, suggesting that ClpE allows the bacteria to adapt to different host environments by inducing the expression of special proteins.

To determine heat-shock protein (Hsp)90 expression is connected with cellular apoptotic response to heat stress and its mechanism, chicken (Gallus gallus) primary myocardial cells were treated with the Hsp90 promoter, aspirin, and its inhibitor, geldanamycin (GA), before heat stress. Cellular viability, heat-stressed apoptosis and reactive oxygen species level under different treatments were measured, and the expression of key proteins of the signaling pathway related to Hsp90 and their colocalization with Hsp90 were detected. The results showed that aspirin treatment increased the expression of protein kinase B (Akt), the signal transducer and activator of transcription (STAT)-3 and p-IKKα/β and the colocalization of Akt and STAT-3 with Hsp90 during heat stress, which was accompanied by improved viability and low apoptosis. GA significantly inhibited Akt expression and p-IKKα/β level, but not STAT-3 quantity, while the colocalization of Akt and STAT-3 with Hsp90 was weakened, followed by lower cell viability and higher apoptosis. Aspirin after GA treatment partially improved the stress response and apoptosis rate of tested cells caused by the recovery of Akt expression and colocalization, rather than the level of STAT-3 (including its co-localization with Hsp90) and p-IKKα/β. Therefore, Hsp90 expression has a positive effect on cellular capacity to resist heat-stressed injury and apoptosis. Moreover, inhibition of Hsp90 before stress partially attenuated its positive effects.

OBJECTIVETo determine the partial sequence of virus strains causing an aseptic meningitis outbreak in northern part of Jiangsu province in 2003 and to compare them with the same serotype strains isolated in other countries to better understand its genetic characteristics and hereditary trend of development.

METHODSVirus RNA was amplified using two sets of specific enteroviral 3' half of VP1 primers 012/011 and 040/011. Polymerase chain reaction (PCR) products were purified and sequenced. BLAST program was then used to perform on nucleotide and amino acid pairwise-alignment with all available sequences in NCBI database. Phylogenetic trees were drawed to compare with other enteroviral sequences using PHYLIP software.

RESULTSUnder BLAST program, three sequences we submitted to GenBank were identically inferred as echovirus type 30, which had been identified by neutralization test in previous study. Phylogenetic analysis demonstrated that strains isolated from this outbreak were aggregated into a cluster, and the closest relationships with them were those isolated in 1999 and 2000. This phenomenon indicated that Echo30 from this outbreak was different from other strains in different epidemic area.

CONCLUSION3' half of VP1 sequence could be used to quickly identify the serotype of isolated enterovirus. Strains isolated from this outbreak had the similar hereditary developing trend comparing with Echo30 strains isolated from other countries.

Volatile organic compounds (VOCs) in ambient air can participate in photochemical reactions, which lead to the generation of secondary pollutants such as ozone and aerosol. So real-time and accurate monitoring of atmospheric VOCs plays an important role in the study of the causes of air pollution. On the basis of proton transfer reaction mass spectrometry (PTR-MS) research, a novel dipolar proton transfer reaction mass spectrometer (DP-PTR-MS) for real-time and on-line monitoring atmospheric VOCs was developed. Compared with the conventional PTR-MS with one kind of reagent ion H3O+, DP-PTR-MS had three kinds of reagent ions H3O+, OH-, (CH)2COH+, which could be switched according to the actual detection need. So DP-PTR-MS can improve the qualitative ability and expand the detection range effectively. The reagent ion H3O+can be used for detecting VOCs whose proton affinities are greater than that of H2O. The reagent ion OH-can be used to identify VOCs cooperating with the reagent ion H3O+,and can also be used for detecting some inorganic substances such as CO2. The reagent ion (CH3)2COH+can be used for accurately detecting NH3under interference elimination circumstances. The limit of detection (LOD) and sensitivity of DP-PTR-MS were measured by using six kinds of standard gases. The results showed that the LOD for detecting toluene was 7×10-12(V/V) and the sensitivity for detecting ammonia has reached 126 cps/10-9 (V/V). The ambient air in Hefei city was on-line and real-time monitored for continuous 78 hours with DP-PTR-MS. The results showed that the newly developed DP-PTR-MS could be used for long-term and real-time monitoring atmospheric VOCs with the concentration of 10-12(V/V) level. DP-PTR-MS is an important tool for the study of the causes of atmospheric pollution and the monitoring of trace VOCs emissions.

Methods Among 6 monitoring sites in Ningxia from 2013 to 2014, multi-stage stratified cluster random sampling method was used, information about risk factors of chronic diseases by were collected questionnaire investigation, a total of 3 527 subjects were effective sample for smoking analysis among 3 540 adults aged 18 and over. After the complex weighting, the smoking status of different nationalities, sexes and age was analyzed. Results The current smoking rate was 29.42% (95% CI:27.91%-30.92%), the current smoking rate of male(56.73%, 95％ CI:54.25%-59.20%) was higher than female (0.92%, 95％ CI:0.50％-1.34％) (P<0.001); The current smoking rate of Han (32.04%, 95% CI:30.24%-33.85%) was higher than Hui (23.09%, 95% CI:20.41%-25.76%). The daily smoking rate of Han (27.98%, 95% CI: 26.25%-29.72%) was higher than that of Hui nationality (19.83%, 95% CI:17.30%-22.36%) (P=0.001), and that of male (49.41%, 95% CI: 46.92%-51.91%) was higher than that of female (0.73%, 95% CI: 0.36%-1.11%) (P<0.001). The average daily smoking of male (20) was higher than that of female (8) (Z=-4.448, P<0.001). Smokers quit smoking rate was 12.54% (95% CI:10.50%-14.57%). Adult secondhand smoke exposure rate was 54.44% (95% CI:52.53%-56.36%). Conclusions The smoking rate of adult residents is high in Ningxia province, but the quit smoking rate is low, male smoking rate is higher than female, Han smoking rates higher than the Hui. The sample population was highly exposed to secondhand smoke. Tobacco control interventions should be taken against high-risk groups.

BACKGROUNDOssification of the ligamentum flavum (OLF) is being increasingly recognized as a cause of thoracic myelopathy. This study was to describe a rare clinical entity of spinal cord kinking (SK) in thoracic myelopathy secondary to OLF.

METHODSThe data of 95 patients with thoracic myelopathy secondary to OLF were analyzed retrospectively. The incidence and location of SK were determined using preoperative magnetic resonance imaging (MRI). The clinical presentation and radiological characteristics in patients with SK were analyzed. Posterior en bloc laminectomy with OLF was performed, and the surgical results were evaluated.

RESULTSSK was found in seven patients (7.4%) based on preoperative MRI. The patients included one male and six females with an average age of 55.6 years (range, 48-64 years). Five patients presented with radiculomyelopathy and two presented with typical thoracic myelopathy of spastic paraparesis. In all cases, the kinking was located just above the end of the spinal cord where the conus medullaris (CM) was compressed by the OLF. The degree of SK varied from mild to severe. The tip of the CM was located between the upper third of T11 to the lower third of L1, above the lower edge of L1. With an average follow-up of 30.4 months, the modified Japanese Orthopedic Association score significantly improved from 5.7 ± 1.8 preoperatively to 8.9 ± 1.4 postoperatively (t = 12.05; P < 0.0001) with an improvement rate of 63.1 ± 12.3%.

CONCLUSIONSSK is a rare radiological phenomenon. It is typically located at the thoracolumbar junction, where the CM is compressed by the OLF. Our findings indicate that these patients may benefit from a posterior decompressive procedure.
