[Objective] To explore the effects of mycocide and insecticide on indoor air quality in archives.[Methocls] The levels of camphor, formaldehyde and 2, 2-dichlorovinyldimethyl phosphate (DDVP) in indoor airwere determined in 17 archives. [Results] The average concentration of camphor in indoor air was 1.00mg/L inarchives applying synthetic camphor, 0.74 mg/m3 in archives applying commercialized mycocide (the main compo-nents were synthetic camphor and pyrethrin ), and 0.14 mg/m3, applying natural camphor. The concentrations offormaldehyde reached 0.297 mg/m3 at the 10th day after the co-fumigation by formaldehyde and DDVP. At thesametime, DDVP was not found in indoor air of archives.[Conclusion]The pollution of formaldehyde and camphorin indoor air of archives should be paid more attention to.

Flow injection on-line sorption preconcentration and separation in a knotted reactor (KR) was coupled to cold vapor atomic fluorescence spectrometry for the determination of trace mercury in mineral water. Mercury was preconcentrated by on-line formation of mercury diethyldithiocarbamate complex (Hg-DDTC) and absorption of the resulting neutral complex on the inner walls of a knotted reactor. A 20%(V/V) HNO3 solution heated by electromagnetic induction heating technique was used as eluent to remove the absorbed Hg-DDTC from the KR, and then the vapor mercury generated by mixing the resulting solution and KBH4 was determined on-line by cold vapor atomic fluorescence spectrometry. The 20% HNO3 was employed as both the efficient eluent and the required acidic medium for subsequent mercury vapor generation in our work. Using 20% HNO3 instead of conventional organic solvent as eluent, the proposed method is simple, easy operational and environmentally friendly. Under the optimal experimental conditions, the sample throughput was approximatively 30/h with an enhancement factor of 35. The detection limit of mercury was 2.0 ng/L. The precision(RSD, n=11) was 2.2% at the 0.1 μg/L Hg2+ level.

Background and purpose: Death-associated protein kinase-1(DAPK) is a pro-apoptosis protein,and plays a important role in oncogenesis and development.This study is to investigate the expression of mRNA of DAPK1 and its association with apoptosis in papillary thyroid carcinoma(PTC).Methods:The expression of DAPK1 mRNA was detected by in situ hybridization in 45 cases of PTC and 45 cases of normal thyroid tissues next to tumors that consist of three part of tissue: normal thyroid tissue,nodular goiter and follicular adenoma.The apoptosis in corresponding issues was tested by TUNEL assay and the apoptosis index(AI) was evaluated.Results:The positive rate of DAPK1mRNA in PTC and para-PTC tissues were 37.78% and 71.11%,respectively.The positive rate of DAPK1 mRNA in counterpart thyroid issues was higher than that in tumor tissues(P0.05).Conclusions:As an apoptosis promoter,DAPK1 may function as an inhibitor of tumor,and low expression or loss DAPK1 gene may be involved in the oncogenesis of PTC.The detection of the expression of DAPK1 may be helpful for judging metastasis and prognosis of PTC.

Objective:To investigate the migration and odontogenesis of rat dental pulp cells transfected with adenovirus vector enco-ding cadherin-11.Methods:The dental pulp cells were cultured and transfected with pDC316-mCMV-EGFP-Cadherin-11.Cad-11 protein expression of the cells was examined by immunohistochemistry staining.The odontogenic differentiation of the cells was studied by alizarin red staining and ALP staining.The adhesion and migration of the cells were tested.Results:Transfection of pDC316-mC-MV-EGFP-Cadherin11 promoted Cad-11 protein expression and ALP activity,increased calcified nodule formation(P <0.05),adhe-sion and migration of rat dental pulp cells(P <0.05).Conclusion:Cadherin-11 may promote the odontoblast differentiation and mi-gration of rat dental pulp cells.

Objective: To analyze influencing factors of in-stent restenosis after coronary artery stent implantation, to provide theoretical support for clinical prevention of restenosis. Methods: Clinical data of 123 patients, who received coronary artery stent implantation in our hospital from Mar 2011 to Sep 2013 and received coronary angiography follow-up one year after operation, were retrospectively analyzed. In-stent restenosis was regarded as stenosis of inner diameter of implanted stent≥50%, so patients were divided into restenosis group (n=35) and non-restenosis group (n=88). Multi-factor Logistic regression analysis was used to analyze influencing factors of coronary in-stent restenosis. Results: Compared with non-restenosis group, there were significant reductions in serum level of total bilirubin [(14.02±6.76) μmol/L vs. (10.90±4.51) μmol/L] and stent diameter [(3.06±0.86) mm vs. (2.87±0.44) mm] in restenosis group, P<0.01 both. Multi-factor Logistic regression analysis indicated that blood glucose level was independent risk factor for restenosis after coronary artery stent implantation (OR=2.545, P=0.035), while stent diameter and serum level of total bilirubin were its protective factors (OR=0.857, 0.850, P<0.05 both). Conclusion: Blood glucose level is an independent risk factor for restenosis after coronary artery stent implantation, while stent diameter and serum level of total bilirubin are its protective factors.

A 59-year-old female farmer presented with left painful swollen eye for 1 week after being stung by a rice black bug ( Scotinophara sp. ). It was associated with acute progressive blurring of vision. On examination of the left eye, there was a marked periorbital swelling with proptosis and complete ptosis. The extraocular movements were restricted in all the directions. The cornea was hazy with large epithelial defect. Fundoscopy showed combined features of both central retinal vein and artery occlusions with swollen optic disc and ischaemia of the macular area. CT scan and MRI of orbit and brain showed evidence of orbital soft tissue inflammation. Patient was diagnosed with left orbital cellulitis, keratouveitis and central retinal vein and artery occlusions. The periorbital swelling and proptosis were improved after treatment with systemic and topical antibiotics. However, the vision remained no perception of light(NPL)and limitation of ocular movements persisted. The potential ophthalmic insults by Scotinophara sp. Can be severe and permanent. Awareness of the debilitating insults by Scotinophara sp. To human eye should be instilled timely especially in its prone areas.

Background: Antiphospholipid syndrome (APS) is an autoimmune disorder characterised by thrombosis and/or pregnancy morbidity in the presence of antiphospholipid antibodies (aPLs) based on the Sydney criteria. We aimed to explore the clinico-laboratory features and treatment strategies of APS patients retrospectively. Methodology: The medical records of APS patients registered under Hospital Universiti Sains Malaysia (Kelantan state) between 2000 and 2015 were reviewed. Results: A total of 17 APS subjects (age 40.7 ± 12.8 years) including 11 primary (64.7%) and six secondary APS (35.3%) patients were identified. The follow-up period was 9.5 ± 6.7 years with male:female ratio of 1.0:4.7. Pregnancy morbidity was the most common clinical manifestation (11/14; 78.6%) followed by recurrent venous thrombosis (10/17; 58.8%). For other clinical features, menorrhagia was the most frequently observed manifestation (4/14; 28.6%) followed by aPLs-associated thrombocytopenia (4/17; 23.5%) and ovarian cyst (3/14; 21.4%). LA and aCL were positive in 94.1% (16/17) and 81.8% (9/11) of the patients, respectively. APTT value (76.7 ± 17.0 sec) was significantly high (p < 0.05). Low intensity warfarin alone was successful to maintain target INR (2.0 - 3.0) and prevent recurrence of thrombosis. Conclusion: The tendency of pregnancy morbidity in this cohort of Malaysian Kelantanese APS patients was high compared to other previously reported APS cohorts. Low intensity warfarin was successful in preventing recurrence of thrombosis, however, APS women receiving long-term anticoagulants should be monitored for possible occurrence of menorrhagia and ovarian cysts.

Objective To study the incidence of rapid eye movement sleep behavior disorder (RBD) and its impact on the clinical manifestations of patients with Parkinson' s disease (PD). Methods One hundred and twenty-four PD patients were included into this study and each of them was given the non motor symptoms questionnaire (NMSquest) to investigate the incidence of RBD. The PD patients were then divided into the RBD group and non RBD group, according to their answers to the NMSquest. Then the clinical differences were investigated between PD patients with and without RBD on the aspects of demographic characters, Hoehn-Yahr (H-Y) stage, the scores of Unified Parkinson Disease Rating Scale (UPDRS) sub-items, the incidence of non motor symptoms, and the dysfunctions of non motor systems (cognitive impairment, anxiety, depression and sleep disorders ). The evaluation tools of non motor functions include Mini Mental State Exam ( MMSE), Hamilton Depression Scale (HAMD), Parkins' s Disease Sleep Scale (PDSS) and Epworth Sleepiness Scale (ESS). Results ( 1 ) 62.9% (78/124) of the PD patients have been experiencing RBD. (2) The course of the disease in RBD group ( 3.8 ± 2.8 ) was significantly shorter than non RBD group (5.0 ± 2.5, t = - 1. 972, P = 0. 048 ) while the sex, age, onset age and the mode of onset, Levodopa dose equivalents (LDE) and the kinds of medicines showed no difference between the two groups. (3) H-Y stage, the scores of UPDRS sub-items and the incidence of motor complications showed no difference between RBD and non RBD group. (4) Most of the non motor symptoms, including the gastrointestinal dysfunctions, autonomic dysfunctions, mood disorders and sleep disturbances, occurred much frequently in RBD group, however, the scores of MMSE, HAMD, HAMA,PDSS and ESS showed no difference between the RBD and non RBD group. Conclusion RBD commonly occurred in PD patients, and PD patients with RBD have a tendency to suffer from dysfunction of non motor systems.

ObjectiveTo investigate the clinical therapeutic effect and safety of solifenacin suceinate in the treatment of overactive bladder symptom after benign prostatic hyperplasia (BPH)operation.MethodsAmong 115 patients receiving BPH surgery,58 cases were given solifenacin at bedtime 4 d after surgery for 20 d (treatment group),and 57 cases were given anisodamine after surgery (control group).The urination of patients before and after pulling out catheter were observed,and urodynamic examination,international prostatic symptoms score (IPSS) and overactive bladder symptom score (OABSS) were used to evaluate urination status.ResultsIn treatment group,IPSS and OABSS decreased from 28.3 to 11.3 score and from (14.2±1.2) to (2.9±0.7) score before and after treatment,respectively (P＜0.01).In control group,IPSS and OABSS decreased from 27.3 to 11.8 score (P＜0.01) and from (14.2±1.6) to (11.3±1.1) score before and after treatment,respectively (P＞0.05).ConclusionsThe proper use of solifenacin after prostate operation may release bladder distress and facilitate rehabilitation in patients with overactive bladder symptom.
