OBJECTIVETo investigate the effect of acupuncture combined behavior intervention on children with autism.

METHODSPatients were treated by "Jin's three-needling" as the main measure with the assistance of behavior intervention, and the changes were compared among the three groups (29 cases in combination group, 15 cases in acupuncture group and 10 cases in intervention group) before and after treatment of various factors and scores estimated by the autism behavior checklist (ABC) and autism development checklist (ADC).

RESULTSIn the combination group, the total scores of ABC and most factors of ABC including body movement, social communication and language factor were improved significantly after treatment (P < 0.01), but there was no significant changes in sense factor and daily life self-caring factor (P > 0.05). Comparison of most items of ADC before and after treatment also showed significant difference (P < 0.01).

CONCLUSIONAcupuncture combined behavior intervention has better therapeutic efficacy in the treatment of children with autism.

BACKGROUND: The study was conducted to investigate the current status of the occupational health and safety management system (OHSMS) in the construction industry and the effect of OHSMS on accident rates. Differences of awareness levels on safety issues among site general managers and occupational health and safety (OHS) managers are identified through surveys. METHODS: The accident rates for the OHSMS-certified construction companies from 2006 to 2011, when the construction OHSMS became widely available, were analyzed to understand the effect of OHSMS on the work-related injury rates in the construction industry. The Korea Occupational Safety and Health Agency 18001 is the certification to these companies performing OHSMS in South Korea. The questionnaire was created to analyze the differences of OHSMS awareness between site general managers and OHS managers of construction companies. RESULTS: The implementation of OHSMS among the top 100 construction companies in South Korea shows that the accident rate decreased by 67% and the fatal accident rate decreased by 10.3% during the period from 2006 to 2011. The survey in this study shows different OHSMS awareness levels between site general managers and OHS managers. The differences were motivation for developing OHSMS, external support needed for implementing OHSMS, problems and effectiveness of implementing OHSMS. CONCLUSION: Both work-related accident and fatal accident rates were found to be significantly reduced by implementing OHSMS in this study. The differences of OHSMS awareness between site general managers and OHS managers were identified through a survey. The effect of these differences on safety and other benefits warrants further research with proper data collection.

OBJECTIVETo observe the clinical efficacy on primary dysmenorrhea treated with isolated herbal moxibustion on Shenque (CV 8).

METHODSOne hundred and two cases were randomized into isolated herbal moxibustion group and western medication group, 51 cases in each one. In isolated herbal moxibustion group, the cases were treated with isolated herbal moxibustion on Shenque (CV 8), and in western medication group, analgesic was administered.

RESULTSIn isolated herbal moxibustion group, 17 cases were cured, 21 cases effective markedly, 9 cases effective and 4 cases failed. The total effective rate was 92.2%. In western medication group, 7 cases were cured, 11 cases effective markedly, 21 cases effective and 12 cases failed. The total effective rate was 76.5%. The comparison of the total effective rates between two groups indicated significant difference in statistics (P < 0.01), in which, the result in isolated herbal moxibustion group was superior to that in western medication group. In comparison of dysmenorrhea score before and after treatment and side effects of two groups, the significant differences presented in statistics, in which, the results in isolated herbal moxibustion group were superior to those in western medication group (all P < 0.01).

CONCLUSIONThe isolated herbal moxibustion on Shenque (CV 8) is superior to oral medication of analgesic for primary dysmenorrhea and it deserves to be promoted due to its advantages on safety, less side effect and good compliance of patients.

OBJECTIVETo investigate whether α-hemoglobin stabilizing protein (AHSP), the α-globin-specific molecular chaperone, is regulated by erythroid transcription factor NF-E2.

METHODSWe established the stable cell line with NF-E2p45 (the larger subunit of NF-E2) short hairpin RNA to silence its expression. Western blot, real-time polymerase chain reaction, and chromatin immunoprecipitation (ChIP) analysis were performed to detect the expression of AHSP, the histone modifications at AHSP gene locus, and the binding of GATA-1 at the AHSP promoter with NF-E2p45 deficiency. ChIP was also carried out in dimethyl sulfoxide (DMSO)-induced DS19 cells and estrogen-induced G1E-ER4 cells to examine NF-E2 binding to the AHSP gene locus and its changes during cell erythroid differentiation. Finally, luciferase assay was applied in HeLa cells transfected with AHSP promoter fragments to examine AHSP promoter activity in the presence of exogenous NF-E2p45.

RESULTSWe found that AHSP expression was highly dependent on NF-E2p45. NF-E2 bound to the regions across AHSP gene locus in vivo, and the transcription of AHSP was transactivated by exogenous NF-E2p45. In addition, we observed the decrease of H3K4 trimethylation and GATA-1 occupancy at the AHSP gene locus in NF-E2p45-deficient cells. Restoration of GATA-1 in G1E-ER4 cells in turn led to increased DNA binding of NF-E2p45.

CONCLUSIONNF-E2 may play an important role in AHSP gene regulation, providing new insights into the molecular mechanisms underlying the erythroid-specific expression of AHSP as well as new possibilities for β-thalassemia treatment.

INTRODUCTIONThere is little detailed information on human immunodeficiency virus (HIV) amongst older adults in Singapore.

MATERIALS AND METHODSA retrospective study of 121 consecutive referrals of patients presenting for HIV care was conducted. Demographic, clinical and laboratory variables were collected. A prognostic model derived from the North American Veterans' Affairs Cohort Study (VACS) was used to estimate prognosis.

RESULTSThe median age at presentation was 43 (range, 18 to 76). Thirty-eight patients (31%) were aged 50 or older and 106 patients (88%) were male. Older patients were more likely to be of Chinese ethnicity (P = 0.035), married (P = 0.0001), unemployed or retired (P = 0.0001), and to have acquired their infection heterosexually (P = 0.0002). The majority of patients in both groups were symptomatic at presentation. Eighty-one (67%) had CD4 counts less than 200 at baseline with no observable differences in HIV ribonucleic acid (RNA) or clinical stage based on age. Non-Acquired Immunodeficiency Syndrome (AIDS) morbidity was observed more frequently amongst older patients. The estimated prognosis of patients differed significantly based on age. Using the VACS Index and comparing younger patients with those aged 50 and above, mean 5 year mortality estimates were 25% and 50% respectively (P <0.001). A trend towards earlier antiretroviral therapy was noted amongst older patients (P = 0.067) driven mainly by fewer financial difficulties reported as barriers to treatment.

CONCLUSIONOlder patients form a high proportion of newly diagnosed HIV/AIDS cases and present with more non-AIDS morbidity. This confers a poor prognosis despite comparable findings with younger patients in terms of clinical stage, AIDS-defining illness, CD4 count and HIV viral load.

OBJECTIVETo evaluate the effect of 90Y-DOTATOC and 131I-MIBG in treatment of metastatic medullary thyroid carcinoma (MTC).

METHODSTwelve histologically confirmed patients with metastatic MTC were included. All patients underwent both 111In-DTPA-octreotide imaging and 131I/ 123I-meta-iodobenzylguanidine (MIBG) imaging. According to the results of the combined imaging, positive patients were selected to be treated with 90Y-DOTA-D-Phe1-Tyr3-octreotide (90Y-DOTATOC) or 131I-MIBG, respectively. The therapeutic procedures of targeted internal radiation were performed with 3.33 GBq 90Y-DOTATOC at 6-week intervals, or 11.1 GBq 131I-MIBG with a minimum interval of three months.

RESULTSThe imaging procedure was positive in all 12 patients: 111In-DTPA-octreotide imaging in eight patients, 131I/ 123I-MIBG imaging in six patients. According to the results of combined imaging, we identified four patients to be treated with 90Y-DOTATOC, and five patients with 131 I-MIBG. After three to five sessions of treatment, three patients with partial remission and six with stable disease were observed. The effective rate was 3/9 (33.3%) and the overall tumor response rate was 9/9 (100%). No relevant toxicity was observed.

CONCLUSIONThe combined imaging technique can be used to identify patients for effective radionuclide treatment. The treatment with 90Y-DOTATOC or 131I-MIBG is well tolerated and may improve the fate of patients with metastatic MTC.

This case report describes the diagnosis and endodontic therapy of maxillary fused second and third molars, using cone-beam computed tomography (CBCT). A 31-year-old Chinese male, with no contributory medical or family/social history, presented with throbbing pain in the maxillary right molar area following an unsuccessful attempted tooth extraction. Clinical examination revealed what appeared initially to be a damaged large extra cusp on the buccal aspect of the distobuccal cusp of the second molar. However, CBCT revealed that a third molar was fused to the second molar. Unexpectedly, the maxillary left third molar also was fused to the second molar, and the crown of an unerupted supernumerary fourth molar was possibly also fused to the apical root region of the second molar. Operative procedures should not be attempted without adequate radiographic investigation. CBCT allowed the precise location of the root canals of the right maxillary fused molar teeth to permit successful endodontic therapy, confirmed after 6 months.

OBJECTIVEFructose-1, 6-diphosphate (FDP), serving as a cellular energy substance, has shown its roles in the treatment of hypoxic-ischemic encephalopathy and myocardial damage. The present study aimed at exploring the potentiality of the protective effect of FDP against ultrastructural damage of the hippocampus caused by febrile seizures (FS) in rats.

METHODSThirty-six 21-day-old male Sprague-Dawley rats were randomly divided into three groups: untreated FS (control), high-dose FDP-treated FS and low-dose FDP-treated FS. FS were induced by hyperthermal bath. Thirty minutes before FS induction, rats in the high-dose and low-dose FDP-treated groups received a peritoneal injection of FDP at a dosage of 50 and 25 mg per 100 g of body weight respectively, whereas the same volume of 0.9% sodium chloride solution were injected to the rats in the control group. Transmission electron microscopy was used to examine the ultrastructural pathologic changes of neurons and organelles as well as the features of synaptic morphological parameters in the hippocampal CA1 area.

RESULTSNeuronal degeneration and necrosis, mitochondria swelling, polyribosomes disaggregation from endoplasmic reticula, and golgiosomes dilation in the hippocampal CA1 area in the two FDP intervention groups were less severe compared with the control group. FDP treatment resulted in significant increases in postsynaptic density thickness (F=12.47, P<0.01), synaptic active zone length (F=14.75, P<0.01) and synaptic interface curvature (F=3.77, P<0.05), as well as a shorter interspace of neural synapses (F=7.29, P<0.01) when compared with the control group. There were no significant differences in the ultrastructural changes between the two FDP treatment groups.

CONCLUSIONSFDP can ameliorate ultrastructural damage in the hippocampus caused by FS in rats. However, further research is warranted for a reasonable and effective dosage of FDP.

OBJECTIVETo investigate the current smoking regulations and their impacts on the environmental tobacco smoke (ETS) levels inside restaurants and bars in Beijing.

METHODSTelephone survey was used to investigate the smoking regulations. TSI Sidepak AM510 was used to measure the level of fine particles less than 2.5 microns in diameter (PM2.5) in restaurants and bars. Analysis of variance and non-parametric rank tests were used to examine the association between indoor and outdoor PM2.5 levels and (1) smoking regulations; and (2) types of restaurants and bars.

RESULTSOf the 305 restaurants and bars surveyed, 27.9% had complete or partial smoking prohibiting rules. The average indoor PM2.5, level of the 92 restaurants and bars was 253.08 microg/m3 , 102.37% higher than the outdoor level. The average indoor and outdoor PM2.5 levels in the restaurants and bars with smoking ban regulations were 93.10 microg/m3 and 110.33 microg/m3 whole 289.34 microg/m3 and 128.40 microg/m3 in those without, respectively. The average indoor and outdoor PM2.5 levels of bars were 413.46 microg/m3 and 190.62 microg/m3, respectively, while in the western fast-food restaurants, they were 83.86 microg/m3 and 104.77 microg/m3, respectively. The outdoor PM2.5 levels were higher than the indoor levels in different classes of restaurants and bars. Furthermore, there was a significant positive correlation between PM2.5 levels and the number of smokers per cube meters (r = 0.47, P < 0.001).

CONCLUSIONSmoking regulations could effectively reduce the ETS level in restaurants and bars.

OBJECTIVETo study the activation of sterol regulatory element binding protein (SREBP) and its critical role in endothelial cell migration.

METHODSBovine aortic endothelial cells (ECs) were cultured. The expression of SREBP and Cdc42 were determined by Western blot and quantitative real-time PCR. Moreover, outward growth migration model and transwell chamber assay were used to detect ECs migration.

RESULTS(1) SREBP was activated during ECs migration. Western blot analysis demonstrated increased active form SREBP in migrating as compared to non-migrating ECs population. SREBP activation decreased as ECs migration slowed;(2) Coincidental with SREBP activation, mRNA expression of its target genes such as low density lipoprotein receptor, HMG-CoA reductase, and fatty acid synthase also increased in migrating ECs population as detected by real-time PCR; (3) Migration induced SREBP activation in ECs was inhibited by SREBP-acting protein RNAi and pharmacologically by 25-hydroxycholesterol; (4) Inhibition of SREBP led to decreased ECs migration in various models; (5) Cells genetically deficient in SREBP-acting protein, S1P, or S2P, phenotypically exhibited impaired migration; (6) SREBP inhibition in ECs suppressed the activity of small GTPase Cdc42, a key molecule for ECs motility.

CONCLUSIONSSREBP is activated during and plays a critical role in ECs migration. Targeting SREBP could become a novel approach in fighting diseases involving abnormal ECs migration.
