AIM:To explore the clinical value of combined detection of C-reactive protein ( CRP ) , erythrocyte sedimentation rate ( ESR) and white blood cell ( WBC) count in patients with ocular syphilis.
METHODS:Dates of CRP, ESR, WBC, TPPA and RPR of 51 ophthalmopathy patients caused by syphilis and 50 normal control from Jan. 2012 to Dec. 2015 in eye hospital were recruited and analyzed statistically.
RESULTS:The positive rates of CRP, ESR and WBC of oculopathy patients were 16%, 18% and 39%, respectively, which were higher than those in the control group. In patients group, the positive rate of ESR was higher than CRP and WBC. There were no obvious relationships between RPR titers and positive ratios of CRP, WBC and ESR.
CONCLUSION: The blood level of CRP, WBC and ESR may have certain help in estimating and monitoring condition of patients with ocular syphilis.

BACKGROUND: Previous studies have demonstrated that berberine represses multiple tumors and tumor stem cells, but the effect of berberine on lung cancer stem cells (LCSCs) remains unclear. OBJECTIVE: To explore the effect of berberine on the proliferation and apoptosis of LCSCs and the possible mechanism. METHODS: CD133+ LCSCs were separated from A549 cells by immunomagnetic beads. The effects of different concentrations (0, 2.5, 5, 10, 20, 40 mg/L) of berberine on the proliferation and apoptosis of LCSCs were determined by MTT and flow cytometry analysis, respectively. In order to further affirm the effect of berberine on the proliferation and apoptosis of LCSCs, the expression levels of Ki67, Bax and Bcl-2 protein were detected by western blot. In addition, to investigate the potential mechanism by which berberine exerts regulatory effects on LCSCs, the expression levels of Hedgehog signaling pathway-associated proteins (PTCH1, SHH, Gli-1 and SMO) were determined. RESULTS AND CONCLUSION: After magnetic cell sorting, the content of the CD133+ fraction was enriched up to 84.13%. MTT and flow cytometry assays showed that berberine inhibited proliferation and promoted apoptosis of LCSCs in a concentration-dependent manner. Western blot analysis showed that the expression levels of Ki67, Bcl-2, PTCH1, SHH, Gli-1 and SMO proteins of LCSCs cultured in the medium with 20 mg/L berberine were dramatically decreased compared to the control, while the expression level of Bax protein was markedly increased compared to the control. These findings suggest that berberine may inhibit proliferation and promote apoptosis for LCSCs through the Hedgehog signaling pathway.BACKGROUND: Previous studies have demonstrated that berberine represses multiple tumors and tumor stem cells, but the effect of berberine on lung cancer stem cells (LCSCs) remains unclear.

OBJECTIVE: To investigate the current situation of early diagnosis and intervention in 0-9 months old infants with hearing loss and analysis factors that will affect early diagnosis and intervention. METHOD: One hundred and eighty-six infants referred to the West China hospital from February 2014 to September 2014 were included. All 186 children were referred due to the fact that either they failed infant hearing screening or outer ear malformation. Early diagnosis and/or intervention were performed on those 186 children and their records of early diagnosis and intervention were analyzed. RESULT: Among the 186 infants, 167 (89.8%) were diagnosed with an average age at (4.0 ± 1.4) months. Among the 167 infants with final diagnosis, there were 31 (18.6%) infants diagnosed as conductive hearing loss (CHL), and 99 cases (59.3%) diagnosed as sensorineural hearing loss (SNHL), among whom, there were 75 (44.9%) bilateral SNHL and 24 (14.4%) unilateral SNHL. There were 2 cases (1.20%) with SNHL on one side and atresia on the other side. 5 (2.99%) of all conductive hearing loss cases with unilateral atresia and 2 cases with auditory neuropathy (AN) were found. 33 infants (19.8%) were found to have normal hearing. 30.7% (23/75) infants diagnosed as bilateral SNHL and 8.3% (2/24) infants diagnosed as unilateral SNHL were fitted with hearing aids. The fitting rate in infants with bilateral SNHL with mild, moderate, severe to profound degrees were 0 (0/23), 24.0% (6/25), 66.7% (6/9), 61.1% (11/18) respectively. The average intervention age was (5.0 ± 2.1) months. CONCLUSION Although the early diagnosis and intervention situation in this study are very close to international standard, there are still infants without final diagnosis and infants with hearing loss without hearing aid fitting. Further studies and efforts to promote early diagnosis and intervention in infants with hearing loss are needed.

Current materials used for maxillofacial prostheses are far from ideal,and how to develop a final prosthetics material is a significant topic in the research of maxillofacial prostheses.In this paper,some pertinent research of silicone elastomeric materials,such as mechanical properties and colorant are reviewed.

Objective To evaluate the mechanical properties of SEI silicone for maxillofacial prosthesis before and after heat aging and explore its clinical value. Methods Two kinds of silicones, SEI and A-2186, were performed heat aging for 24, 48 and 72 h. The parameters of tear strength, tensile strength, elongation at break and hardness of them were detected under ordinary state and at different time points after heat aging. Statistic comparison and analysis were conducted. Results Tear strength, tensile strength and elongation at break of A-2186 silicone were more favorable than those of SEI silicone under ordinary state, while the parameter of hardness was an exception (P < 0.05). After heat aging and with time progress, tear strength, tensile strength and elongation at break significantly decreased and hardness significantly increased for both A-2186 silicone and SEI silicone (P < 0.05). After heat aging, tear strength and tensile strength of A-2186 silicone were more favorable than those of SEI silicone, while the latter had a minor change in hardness. Conclusion Compared with the worldwide commonly used A-2186 silicone, there is room for improvement in tear strength and tensile strength for SEI silicone. Given the favorable property of minor change in hardness after heat aging, SEI can be used as a prosthetic material for facial soft tissue defect.
