Purpose To investigate the expression of sphingosine-1 phosphate receptor 1 (S1PR1) and sphingosine-1 phosphate receptor 4 (SIPR4) in triple negative breast carcinoma (TNBC) and to evaluate its correlation with the clinicopathologic features of TNBC. Methods 72 cases of tissue slides of TNBC were stained immunohistochemically and analyzed with image processing to calculate the S1PR1 and S1PR4 expression. Correlations of the S1PR1 and S1PR4 expression with the clinicopathologic features of TNBC were studied. Results Ki-67 index of high, moderate and low expression of the S1PR1 in TNBC were 48.89%, 36.11% and 26.48%, respectively. The difference among them was significance (P<0.001). Ki-67 index of high, moderate and low expression of the S1PR4 in TNBC were42.83%, 31.43% and 28.93%, respectively. The difference among them was significance (P = 0.007 ). The positive rate of lymph node of high, moderate and low expression of the SI PR1 in TNBC were 31.4%, 48.6% and 20.0%, respectively. The difference among them was significance (P = 0.012). The positive rate of lymph node of high, moderate and low expression of the S1PR4 in TNBC were 54.3%, 40.0% and 5.7%, respectively. The difference among them was significance (P=0.010). The CD68 positive rate of high, moderate and low expression of the S1PR1 in TNBC were 47.22%, 42.59% and31.48%, respectively. The difference among them was significance (P = 0.036). Both the difference of survive rate among high, moderate and low expression of the S1PR1 and S1PR4 were not significance (P = 0.209 and P =0.593 ). Conclusion High expression of S1PR1 and S1PR4 may contribute to the cellular proliferation and lymph node metastases in TNBC. The survive rate of TNBC maybe not related with both the S1PR1 and S1PR4 expression.

INTRODUCTION:
Nail psoriasis treatment is challenging due to difficult drug delivery and systemic therapy toxicities. Self-dissolvable microneedle patches embedded with corticosteroids offers a potentially rapid, minimally invasive drug delivery platform with good efficacy and minimal adverse side effects.
METHODS:
We conducted a 4-month prospective randomised controlled trial. Subjects with psoriatic nails were randomised to receive microneedle device delivered topical steroids on one hand and control treatment (topical Daivobet gel) on the other. Two independent dermatologists blinded to the treatment assignment scored their Nail Psoriasis Severity Index (NAPSI) during visits at baseline, 2 and 4 months. All treatment was discontinued after 2 months. Average NAPSI score on each hand was analysed.
RESULTS:
A total of 25 participants were recruited, aged 22 to 73 years. Majority were Chinese (72%), followed by Indian and Malay. There was equal randomisation of treatment to the left and right nail. While there was a rapid significant improvement in average NAPSI score for the control arm at 2 months, the treatment arm had a greater, more sustained improvement of the NAPSI score at 4 months. The average NAPSI score improved for both treatment and control group at 4 months compared to baseline. However, only the NAPSI value improvement in the controls at 2 months compared to baseline was statistically significant (P=0.0039). No severe adverse effects were reported.
CONCLUSION
To the best of our knowledge, this is the first prospective randomised control trial comparing microneedle technology against conventional topical steroids in nail psoriasis treatment. Our findings demonstrate microneedle technology is as efficacious as topical therapy.

OBJECTIVETo understand the exposed positions and levels of indium and its compounds in manufacture of liquid crystal displays, and to evaluate the degree of occupational hazard from indium and its compounds.
METHODSOn-site investigation of occupational health, occupational hazard monitoring, and occupational health examination were used to evaluate the degree of occupational hazard from indium and its compounds in three manufacturers of liquid crystal display panel in Shenzhen, Guangdong, China.
RESULTSThe time-weighted average (TWA) and short-term exposure limit (STEL) concentrations of indium and its compounds to which sputtering machine operating positions were exposed were less than 0.002~0.004 mg/m³ and 0.006~0.007 mg/m³, respectively, both of which complied with the National Hygienic Standard (PC-TWA = 0.1 mg/m³; PC-STEL = 0.3 mg/m³); the TWA and STEL concentrations of indium and its compounds to which grinding positions were exposed were 0.114~2.98 mg/m³ and 0.31~10.02 mg/m³, respectively, both of which exceeded the National Hygienic Standard with the highest concentration 33-fold higher than the standard. No significant health damages were found in exposed workers according to the results of occupational health examination.
CONCLUSIONThe grinding positions are the key to the control of occupational hazard from indium and its compounds in manufacture of liquid crystal display panel. The workers should be equipped with the anti-particulate full-face respirator, which is an effective way to prevent occupational hazard from indium and its compounds.

OBJECTIVETo evaluate the epidemiological and serological efficacy after 10 years of vaccination against hemorrhagic fever with renal syndrome (HFRS) vaccines in Zhejiang province.
METHODSOne county was randomly chosen as the research unit with all the healthy people between 16 and 60 years old were equally divided into study and control groups. The study group was vaccinated. Immunofluorescent antibody assay was used to test specific IgG antibody and Mcro-CPE method was used to test the titer of neutralizing antibody.
RESULTSTwo weeks after the full-course immunization, the seroconversion rate became 100% (67/67, with 95% CI as 96.3%-100%) by immunofluorescent antibody test (IgG) and 44.4% (8/18 with 95% CI as 22.0%-69.0%) by neutralization test with GMT titers as 72.1 and 4.6 respectively. Booster immunization was provided one year later. Time span as two weeks prior to, one year, one and half years, two years, three years and five years after booster immunization, the rates of seroconversion on immunofluorescent antibody using IFAT method, were 28.6%, 83.3%, 75.0%, 53.1%, 22.6%, 10.0% and 55.0% respectively, and rates of seroconversion of neutralizing antibody by Mcro-CPE method were 14.8%, 55.6%, 35.0%, 31.3%, 26.0%, 10.0% and 50.0% respectively. Nine years after the reinforcement, the rates of seroconversion of immunofluorescent antibody by IFAT method was only 7.1%. The vaccinated group had no patient seen but the control group appeared 34 patients including 3 deaths. According to the ten-year observation, the vaccine seemed effective with the protection rate in population reached 100%.
