Manganese(Mn) is one of the essential trace elements in biologic metabolism.With proper quantity,Mn acts as some enzymes’active groups,reactivators,and participates in the physiological functions of central nervous system.Overdose exposure to Mn in industry may result in occurrence of occupational manganism,which can cause damage of many aspects of the body such as nerve,immunity and reproduction.The aim of present essay is to review the current studies on nerval behavior function and biomarkers of manganism both in China and other countries.

Objective To investigate the organophosphorus pesticides residues in vegetables in Ji'nan,China.Methods From 2005 to 2007,the residues of ten kinds of organaphosphorous pesticides,including methamidophos,parathion-ethyl, parathionm-ethyl,dichlorvos,phorate,monocrotophos,omethoate,dimethoate,chlorpyrifos,malathion were determined in 8 kinds of vegetables by capillary gas chromatography.Results In the 597 vegetables samples,the total detection rate of organaphosphorous pesticides was 32.66%,in 25.63% of the samples,the contents of organaphosphorous pesticides residues exceeded the national standard limits.In leek,the detection rate was 65.56% and the exceeded limit rate was 52.22%.In addition, more than one kind of pesticide could be detected in one kind of vegetable.The concentration of methamidophos,the most serious pollutant,could reach 114.013 mg/kg.Omethoate could also be detected at 11.807 mg/kg.In this investigation,a downtrend was seen in the rate of exceeding standard limits and the difference in seasons in the detection rate of pesticides residues was also seen. Conclusion The detection rate of high toxic organaphosphorous pesticides in vegetables sampled in this study is higher,it indicates that the situation of pesticides abuse is serious in this area.

OBJECTIVETo observe the clinical effect of Ziyin Huoxue Granule (ZHG) combined glucocorticoids and antibiotics in treatment of radiation pneumonitis.

METHODSTotally 70 radiation pneumonitis patients were assigned to the treatment group and the control group according to random digit table, 35 in each group. All patients received glucocorticoids and antibiotics. Patients in the treatment group additionally took ZHG, one dose per day for 4 successive weeks. Watters clinical-radiologic-physiologic (CRP) score, Karnofsky Performance Status Scale (KPS) , and acute radiation injury classification [set by Radiation Therapy Oncology Group (RTOG)] were observed in the two groups before and after treatment. The application time for antibiotics and glucocorticoids was compared between the two groups.

RESULTSAll patients completed this trial, and nobody dropped out or died. There was no statistical difference in Watters-CRP scores, KPS, or RTOG between the two groups before treatment (P > 0.05). Compared with before treatment in the same group, RTOG classification was obviously improved in the two groups (P < 0.05). Compared with the control group, Watters-CRP scores decreased, KPS increased, the application time for antibiotics and glucocorticoids was reduced (P < 0.05). The efficacy of RTOG classification was better in the treatment group than in the control group, but with no statistical difference between the two groups (P > 0.05).

CONCLUSIONZHG combined glucocorticoids and antibiotics was superior in treating radiation pneumonitis to using glucocorticoids or antibiotics alone in elevating Watters-CRP scores, shortening the application time for glucocorticoids and antibiotics, and improving patients' physical conditions.

Objective To observe differences between repeat and written response in speech recognition tests of short Mandarin monosyllable lists. Methods 12 normal-hearing subjects were tested by 6 short monosyllabic lists. The subjects should repeat and write down.the contents of the tests at the same time, the tester monitors au-rally and records the subjects' reactions. The speech recognition scoring error under different responses at different presentation levels could be obtained by comparing the records of the subjects with the tester. Results The speech recognition scoring of repeat and written response were highly correlated with each other (P<0.01). However, 19(26.4%) out of 72 pairs of test records were inconsistent. The error range of them was from -5% to 10%. When the presentation level was 5 dB HL, the difference among the speech recognition scoring was significant statistically, but not significant when the presentation level at 20, 15, 10 and 0 dB HL. Conclusion The test results of speech audiometry are impacted by different respond methods. In the open-set test, it's supposed that the subjects should make notes while repeating the contents of the tests, then compare with the aural monitoring records of the tester to keep the reliability of the test.

Objective To investigate the maturation status of monocytes and their responses to the stimulation of toll like receptor (TLR) ligands during primary HIV-1 infection, and to further understand the correlation between functional status of monocytes and disease progression during primary HIV -1 infection. Methods Peripheral blood mononuclear cells ( PBMCs) were collected from 35 subjects with primary HIV-1 infection and 13 HIV-negative healthy subjects to isolate monocytes .Monocytes were stimulated with LPS and Pam3CSK4, respectively, and cultured for 20 hours.The expression of activaion/inhibitory markers on monocytes were analyzed by flow cytometry before and after stimulation .The secretion of proinflammatory cy-tokines ( IL-1β, TNF-αand IL-6) by stimulated monocytes were detected by ELISA .Results The expres-sion of activation markers CD80, CD86, CD40 and inhibitory marker PD-L1 on monocytes were increased in subjects with primary HIV-1 infection (P<0.001 except for CD86 P=0.01).The level of CD40 was posi-tively correlated with viral load in plasma (P<0.001, R=0.553).Compared with control group, primary HIV-1 infection group showed a less increase in the expression of HLA-DR, CD80, CD86 and PD-L1 on monocytes after stimulation with LPS and Pam3CSK4 (P<0.001), but the secretion of proinflammatory cyto-kines TNF-α(LPS:P=0.004, Pam3CSK4:P=0.012) and IL-6 (LPS:P=0.006) were enhanced in mono-cytes from patients with primary HIV-1 infection.Conclusion Monocytes were activated during primary HIV-1 infection.They secreted higher level of proinflammatory cytokines after stimulation with TLR ligands , indicating monocytes might play a role in microbial translocation and immune activation during HIV -1 infection .

Objective To explore the changes of weight,body mass index(MBI),serum glucose,serum insulin in sodium valproate(VPA)-treated children with epilepsy.Methods The study was carried out in 30 epileptic children treated with VPA for 3 months.Weight,height,serum glucose and insulin levels were conducted before and after VPA treatment.Serum insulin levels were detected by radioimmunoassay.Results After 3 months' treatment,body weight [(15.68?3.82)kg vs(19.64?4.75)kg,t=3.56 P0.05].Conclusions VPA therapy can make insuline weight,BMI,serum insulin increased and may lead to insulin resistance.Insulin resistance may be one of the reasons for weight gain in VPA-treated patients.
