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.

OBJECTIVETo observe the short-term and long-term efficacies on primary dysmenorrhea treated with staging acupoint embedment therapy.

METHODSSeventy cases of primary dysmenorrhea were randomized into an embedment therapy group and a fenbid group, 35 cases in each one. In the embedment therapy group, the embedment therapy was applied twice during the menstrual cycle, one treatment 3 days before menstruation and one treatment during the 12th-14th days of menstruation, respectively. Guanyuan (CV 4), Zigong (EX-CA 1), Diji (SP 8) and Ciliao (BL 32) were the main acupoints in the treatment 3 days before menstruation. Shenshu (BL 23), Ganshu (BL 18) and Pishu (BL 20) were the main acupoints in the treatment during menstruation. In the fenbid group, fenbid was prescribed for oral administration, 0.3 g each time, twice a day, starting 3 days before menstruation till pain was relieved. The treatment of one menstrual cycle was one session. The continuous treatment of 3 menstrual cycles was required. The short-term and long-term efficacies were evaluated at the end of the 3rd cycle and in 3 months after the treatment terminal. The dysmenorrhea score was used to evaluate the efficacy. Visual analogue scale (VAS) and SF-36 were for the assessment of pain degree and life quality.

RESULTS(1) The total effective rate was 91.4% (32/35) in the embedment therapy group after the 3 menstrual cycles, which was better than 74.3% (26/35) in the fenbid group (P < 0.01). In the follow-up stage, the total effective rate was 91.4% (32/35) in the embedment therapy group, which was better than 40.0% (14/35) in the fenbid group (P < 0.01). (2) The differences were not significant in dysmenorrhea score and VAS score after the 1st and 2nd menstrual cycle treatments between the two groups (all P > 0.05). In the 3rd menstrual cycle and the follow-up stage, the dysmenorrhea score and VAS score were reduced obviously in the embedment therapy group as compared with those in the fenbid group (P < 0.05, P < 0.01). The rebound effect occurred in the follow-up stage in the fenbid group. (3) In the 3rd menstrual cycle and the follow-up stage, the improvement in the total score of life quality of the embedment therapy group was superior apparently to the fenbid group (P < 0.05, P < 0. 01).

CONCLUSIONThe staging acupoint embedment therapy achieves the superior short-term and long-term efficacies as compared with the oral administration of fenbid in the treatment of primary dysmenorrhea. As the symptoms of dysmenorrhea and pain are relieved, the life quality is improved.

The association between fasting plasma ghrelin levels and insulin resistance and blood pressure (BP) in octogenarians was investigated in this study. A total of 487 unrelated octogenarians (including 203 men and 284 women) were enrolled in this cross-sectional study at the Healthy Care Center of Shanghai East Hospital, Tongji University, China, from October 2008 to April 2009. Plasma ghrelin was determined by using the enzyme linked immunosorbent assay (ELISA). Insulin sensitivity was assessed using the homeostasis model of assessment-insulin resistance (HOMA-IR). The age of the participants ranged from 80 to 89 years (mean=83.9+/-4.8 years) with a body mass index (BMI) of 25.3+/-4.9 kg/m(2). Plasma ghrelin levels were 20.94+/-5.34 mug/L, being 20.89+/-5.53 mug/L in men and 21.38+/-3.73 mug/L in women respectively. Plasma ghrelin was not associated with systolic (P=0.981) or diastolic (P=0.724) BP, waist circumference (P=0.278), fasting insulin (P=0.246), fasting blood glucose (FBG) (P=0.693) and HOMA-IR (P=0.232). In the control cohort, no significant differences in plasma ghrelin were found between genders (P=0.489), and among subjects with hypertension (BP>140/90 mmHg) (P=0.284) and type 2 diabetes (P=0.776). In conclusion, fasting plasma ghrelin levels are not directly correlated with insulin resistance and BP among octogenarians.

Objective To investigate the changes of phenotypes and function of CD56+T cells during primary HIV-1 infection and their relationship with disease progression.Methods Peripheral blood mononuclear cells (PBMCs) were collected from 53 subjects with primary HIV-1 infection and 31 HIV-1-negative healthy subjects.The percentages of CD56+T cells and the expression of several phenotypic markers on CD56+T cells including CD16, CD161, NKB1, NKG2A, NKp46, NKG2D, NKG2C and CD158a were analyzed by flow cytometry.IFN-γand TNF-αreleased by CD56+T cells with and without K562 stimulation and the levels of cytotoxic molecular CD107a were measured.Results The percentages of CD56+T cells in patients with primary HIV-1 infection were significantly lower than those of healthy subjects (P=0.025). The levels of CD56+T cells were negatively related to the viral loads in plasma samples ( P=0.021, r=-0.316).Compared with healthy subjects, the expression of CD16 (P=0.003), CD161 (P=0.023), NKB1 (P=0.023) and NKp46 (P=0.021) on CD56+T cells were decreased in patients with primary HIV-1 infection.The levels of NKB1 were positively related to the CD4+T cell counts ( P=0.007, r=0.364), but were negatively related to the viral loads in plasma samples (P=0.030, r=-0.299).Sponta-neous secretion of IFN-γand TNF-αby CD56+T cells and the expression of CD107a were dramatically in-hibited in patients with primary HIV-1 infection as compared with healthy subjects ( all P<0.001 ) . Moreover, the killing ability of CD56+T cells against K562 target cells was weakened in patients with prima-ry HIV-1 infection as the levels of IFN-γ-, TNF-α-and CD107a-producting CD56+T cells were significantly decreased (P<0.001 for IFN-γand TNF-α, P=0.016 for CD107a).Conclusion Inhibited expression and altered phenotypes of CD56+T cells were identified during primary HIV-1 infection.Lower levels of cy-tokines and cytotoxic molecular were also detected, indicating the dysfunction of CD56+T cells appeared dur-ing early stage of HIV-1 infection and was associated with disease progression.
