OBJECTIVE: To study the correlation of daily living activities with location and severity of trau- matic brain injury (TBI) and to provide a theoretical basis for improving the accuracy of expert opinion. METHODS: Five hundred and one cases of patients with TBI were selected. Detailed records included following: pre-injury situation, location and severity of injury, treatment and education. Daily living activi- ties scale (Barthel index) was applied to test the subjects' daily living activities. The relevance among location and severity of TBI and Barthel index was statistically analyzed. RESULTS: In mild TBI group, there was no significant difference in Barthel index among each location (P>0.05). In moderate TBI group, there were significant differences in Barthel index between subarachnoid hemorrhage and cerebral lobe injury, also between parietal, occipital lobes injury and frontal lobe injury, parietal, occipital lobes injury and temporal lobe (P<0.05), respectively, whereas no significant difference in Barthel index between frontal lobe injury and temporal lobe injury (P>0.05). In severe TBI, there were significant differences in Barthel index between every two different locations (P<0.05). CONCLUSION There is some correlation between the location of TBI and Barthel index, which provides an important reference value for analyzing and determining daily living activities after TBI.

Objective To investigate the effects of acupoint injection of mouse nerve growth factor (mNGF) on treatment of children with autistic spectrum disorders in different age groups. Methods Totally 80 cases of children with autistic spectrum disorders were divided into control group and experiment group according to random number table method, with 40 cases in each group. The control group was given structured education, ABA behavioral training, sensory integration training, and language training, 30 min for each class, 4 h each day, 5 d a week, for 5 months. At the same time, the control group was also given head needling treatment, once every other day, 3 times a week, 30 times as one treatment course, 2 courses. On the basis of the treatment of the control group, experiment group was given mNGF through acupoint injection, once every other day, 3 times a week, 10 times as one treatment course, 10 d between each treatment course, 5 courses in total. The scores of autism behavior checklist (ABC), children autism and related developmental disorders psychological education rating scale-Chinese version (C-PEP), neuropsychological development scale among children aged 0–6 years in the two groups were compared. Results Compared with before treatment, ABC scores in both group after treatment decreased significantly (P<0.05); ABC scores after treatment in children aged 18–36 months and 37–54 months in the experiment group were lower than those of the control group (P<0.05). Neuropsychological development scale scores in children aged 18–36 months and 37–54 months were better than the control group (P<0.05). Compared with before treatment, C-PEP scores of both groups increased significantly (P<0.05). There was statistical difference in the C-PEP scores in children aged 18–36 months between the two groups after treatment (P<0.05). The C-PEP scores in children aged 18–36 months increased to the highest (P<0.05).Conclusion Acupoint injection of mNGF can improve the clinical symptoms and intelligence of ASD children of all ages, but children can receive better treatment effects at younger ages.

We investigated the pathogenic spectrum of enteroviruses associated with hand, foot and mouth disease (HFMD) in Jinan, China. A total of 274 specimens with a clinical diagnosis of HFMD in Jinan from 2009 to June 2012 were used. A GenomeLab™ (GeXP)-based multiplex reverse transcription-polymerase chain reaction (RT-PCR) assay was employed to simultaneously detect 15 serotypes of human enteroviruses: human enterovirus (EV)71; coxsackievirus A (CVA)16, 4, 5, 6, 9, and 10; CVB1, 3 and 5; echovirus (Echo) 6, 7, 11, 13 and 19. Results showed that all samples were enterovirus-positive, with the most common serotypes being EV71 (25.18%) and CVA16 (16.06%), followed by CVA10 (14.23%), CVA6 (7.30%), CVB1 (1.09%), Echo6 (0.73%), CVA9 (0.36%), CVB3 (0.36%) and co-infections (5.11%). CVA10 and CVA6 had the third and fourth highest prevalence of pathogens for HFMD, respec- tively. The most prevalent season for CVA10 was from April to August, with a peak in April; for CVA6 it was from April to August, with a peak in June. This is the first report of the pathogenic spectrum of en- teroviruses associated with HFMD in Jinan using the GeXP-based multiplex RT-PCR assay. These data will provide the scientific evidence for the prevention and control of epidemics, as well as therapy for HFMD patients.

CTN-1 is one of the rabies vaccine strains for human use in China, but there has been no report on the full-length gene sequence of CTN-1. In this study, the full-length gene of CTN-1 was amplified by RT-PCR, each PCR product was cloned into T vector and then sequenced, assemblied and compared with other vaccine strains as well as the wild Chinese rabies isolates. The phylogenetic tree of G gene was constructed and the genetic homology was analyzed. The results revealed that CTN-1 was 11 925nt (GenBank accession number: FJ959397)in length and belonged to the genotype I. The full-length nucleotide homologies among CTN-1 and other rabies virus strains were between 81.5%-93.4%, of which the lowest 81.5% was between CTN-1 strain and bat isolate SHBRV, and the highest 93.4% was between CTN-1 and Chinese isolate HN10. The phylogenetic analysis revealed that the majority of Chinese isolates could be grouped into the same clade with the CTN-1 strain, but aG and some vaccine strains from abroad such as Flury, PM, PV, ERA, RC-HL and a few Chinese strains were grouped in another clade. Comparsion of the G protein genes also showed that the homologies among CTN-1 and most of the Chinese isolates were higher than that of the other vaccine strains to those Chinese strains. Therefore, it suggests that the CTN-1 strain is more suitable and rational to be used for the production of rabies inactivated vaccine in China than the others.

Objective To assess the level of dietary iodine intake in three areas of Zhejiang and the related policy on universal salt iodization in the province.Methods The study involved 497residents from 180 families living in Hangzhou,Taizhou,Zhoushan cities,representing coastal and inland areas in Zhejiang province in 2009.A total diet study was applied to obtain the typical diet samples at three study areas through food consumption,aggregation,sampling and preparation processes.The contents of iodine in diet samples were determined by tetramethylammonium hydroxide extraction-inductively coupled plasma-mass spectrometry.The amount of dietary iodine intake was calculated by timing the food consumption data and the iodine content in different dietary samples.The safety of dietary iodine intake was evaluated according to the recommended nutrient intake (RNI) and tolerable upper intake level (UL) published by the Chinese Nutrition Society in 2001.Results The dietary iodine intake of reference person in three areas of Zhejiang province was 421.0 μg/d.The levels of P5,P25,median,P75,P90,P95 dietary iodine intake were 145.7 μ g/d,267.6 μg/d,358.5 μg/d,495.6 μ g/d,774.1 μg/d and 1273.0 μg/d respectively.Daily dietary iodine intake at ＜RNI,RNI-UL,＞UL accounted for 5.2％,87.5％ and 7.2％ of all the participants respectively.Without considering the loss through cooking,salt iodine provided 81.6％ of the dietary iodine source.The resources of dietary iodine would include vegetables,cereals and marine food,proportionally,as 57.2％,13.0％ and 8.5％,respectively.Participants whose daily dietary iodine intake exceeded the UL level would consume more marine algae products than those whose dietary iodine intakes were lower than RNI or between RNI-UL.Conclusion Dietary iodine intake among most residents and their average level were among reasonable ranges.Meanwhile,deficiency and excess of iodine intake coexisted.Salt iodine was the main resource of dietary iodine.Participants whose dietary iodine intakes exceeding the UL level,would prefer consume more marine algae products.

Objective To explore the effect of LYRM1 overexpression on production of reactive oxygen species (ROS) in skeletal muscle cells.Methods Rat myoblasts(L6) were transfected with either an empty vector or a LYRM1 expression vector.Cells were screened and the expression of LYRM1 protein in cells was identified.L6 cells were incubated in culture solution with H2-DCFDA after they were differentiated.Then fluorescence intensity of ROS in L6 was observed by fluorescence microscope,and the content of ROS was determined by flow cytometry.Results The relative fluorescence intensity of ROS in L6 overexpressing LYRM1 was 24.8933 ± 4.4574,while that in contrast cells was 13.1512 ± 0.7347,the difference between them was significant(t =24.12,P =0.00).Conclusions Overexpression LYRM1 can increase the production of ROS in skeletal muscle cells.LYRM1 overexpression may be influence the mitochondrial function and induce the mitochondrial damage of skeletal muscle cells.

OBJECTIVETo investigate the effect of cigarette smoking on thyroid gland volume, thyroid function and thyroid autoantibodies in the areas with different iodine intakes.

METHODSA cross-sectional epidemiological study in Panshan (mild iodine-deficient area), Zhangwu (more than adequate iodine intake area) and Huanghua (iodine-excessive area) was conducted in 3761 subjects in 1999.80.2 % of them were followed up in 2004. Questionnaires, thyroid function, thyroid autoantibodies, urinary iodine concentration,and thyroid B ultrasound were performed.

RESULTSThe prevalence of goiter was higher in smokers than in non-smokers (15.1% vs. 11.5%, P< 0.05). The average thyroid volume was higher in smokers with phenomenon more obvious in Panshan and Huanghua areas. Data from logistic analysis showed that smoking cigarette was an independent risk factor of goiter. There was no difference in serum TSH and Tg level between smokers and non-smokers. The positive rate of TPOAb (>100 IU/ml) was higher in smokers than in non-smokers(10.8% vs. 9.0 % , P <0.05) and was especially obvious in Huanghua area. Smoking was a independent risk factor of increasing positive rate of TPOAb. During the prospective observation,it was found that the incidence of positive TPOAb(>,100 IU/ml) was 7.4% in the subjects that were from non-smokers turning to smokers and 2.9% in those whose smoking behavior did not change. Logistic analysis indicated that the shifting from non-smoking to smoking was independent risk factor for the increase on high incidence of positive TPOAb.

CONCLUSIONSmoking cigarette was a independent risk factor of goiter. Smoking was also a risk factor of increasing TPOAb positive rate. Shifting from not smoking to smoking was an independent risk factor of increasing high incidence of positive TPOAb.

OBJECTIVETo explore the factors associated with retention in a community-based methadone maintenance treatment(MMT) among drug users in Urumqi.

METHODSWith national MMT guideline( drift) for heroine addicted drug users, local heroine-dependent people were admitted to community-based MMT program affiliated to Xinjiang Uigur Autonomous Region Center for Mental Health. Data on outpatients' social-demo characteristics, baseline behaviors on drug use and daily stabilized dose of drugs were entered to MMT database.

RESULTSUp to 10, Feb. , 2006,353 persons withdrew MMT treatment among 709 heroin dependant drug users. Between 11, Aug., 2005 and 10, Feb., 2006, with median duration as 77 days, cumulative drop-out rate of 90 days and 180 days after first dose of MMT were 73.8% among 455 and 99.4% among 355 drug users, respectively. The incidence of drop-outs was 29.8 per 100 person-month. The median length of stay (days) in MMT was 68.0 (95% CI: 59.0- 78.0). Correlates of retention were found as: Being Uigur(HR = 1.35;95% CI :1.09-1.67), duration of drug use (HR =0.74; 95% CI:0.55-0.99) and stabilized dose(HR = 0.60;95% CI: 0.48-0.74) was found in multiple Cox proportional hazard regression model.

CONCLUSIONRetention of MMT among drug users in Urumqi was low. Uigur people should be given individual counseling to help them increase the compliance rate. Within the ranges of clinic dosage, adjustment of the methadone dose on an individual base might serve as an appropriate approach to increase the effectiveness of the program.

OBJECTIVETo investigate the quantity and the pathway to damage hematopoietic cells of CD8+CD25+ and CD8+ HLA-DR+ effector T cells in peripheral blood (PB) of severe aplastic anemia(SAA) patients and explore the immunopathogenesis of SAA.

METHODSThe quantity of CD8+ CD25+ and CD8+ HLA-DR+ cells in PB and the expressions of perforin, granzyme B, tumor necrosis factor-beta (TNF-beta) and FasL in 29 SAA (14 untreated and 15 recovered) patients and 12 normal controls were analyzed by flow cytometry.

RESULTSThe fraction of CD8+ CD25+ T cells in CD8+ T cells was (3.67 +/- 2.58)% in untreated SAA patients, (5.19 +/- 4. 29)% in recovered patients and (4.84 +/- 2.31)% in normal controls, and that of CD8+ CD25+ T cells in CD3+ cells in the three groups was (2.25 +/- 1.35)%, (2.98 +/- 1.35)% and (2.11 +/- 1.88)%, respectively. They had no statistic difference among the 3 groups (P >0.05). The fraction of CD8+ HLA-DR+ T cells in CD8+ T cells was (39.30 +/- 8.13)% in untreated patients, which was significantly higher than that in recovered patients [(20.65 +/- 5.38)%] and controls [(18.34 +/- 6.68)%] (P<0.001), while there was no statistic difference between the latter two groups (P>0.05). CD8+ HLA-DR+ T cells in CD3+ cells was (27.81 +/- 7.10)% in untreated group, which was significantly higher than that of recovered group [(12.02 +/- 3.03)%] and controls [(8.50 +/-2.33)%] (P<0.01). And that in recovered group was higher than that in control group (P<0.05). The expressions of perforin, granzyme B, TNF-beta and FasL of CD8+ HLA-DR+ T cells in untreated group were 8.51%, 96.08%, 72.11% and 94.25% respectively, which were higher than those in recovered group (1.78%, 85.20%, 34.38% and 51.20%) and controls (1.86%, 82.09% ,17.92% and 32.91%). There was no statistic difference between recovered patients and controls (P>0.05).

CONCLUSIONThere were elevated quantity of CD8+ HLA-DR+ T cells and high expressions of perforin, granzyme B, TNF-beta and FasL in SAA, which might contribute to the bone marrow failure.
