? AlM: To investigate the therapeutic effects of Pranoprofen on tear dynamic abnormity induced by conjunctivochalasis ( CCh) .
?METHODS: Seventy cases ( 70 eyes ) whose the main symptoms was epiphora induced by CCh were divided into II, Ⅲ and Ⅳ in 3 groups according to Zhang’s grading standards, meanwhile, all the patients were treated with the eye drops of Pranoprofen for 2wk. After that, the curative effect of each group was analyzed before and after treatments according to the symptoms, dye disappearance test, bitter taste test and tear break-up time.
?RESULTS: After 2wk treatment of Pranoprofen, the symptom of patients at grade I and II improved obviously grade Ⅲ improved more, grade Ⅳ did little. The positive rate of dye disappearance was the highest in grade II, the second in grade Ⅲ, and the third in gradeⅣ. There was significant difference among the 3 groups (P<0. 05). The time of bitter taste test was shortened (P<0. 05) and the tear break-up time was prolonged (P<0. 05) in grade II after treatment, however, the time of those in gradeⅢandⅣhad not changed than before ( P>0. 05).
?CONCLUSlON: Pranoprofen has good effects on tear dynamic abnormity induced by grade II of cch.

Objective To understand the air pollution by microorganisms in the underground spaces. Methods 51 underground spaces were investigated, the impact and sedimentation sampling methods were employed and the total bacterial count, mycetes, streptococcus and anaerobes in air were determined. ELESA was used to detect aflatoxin B1 in aspergillus flavus isolated from air. Results The total bacterial count in the air in underground spaces accorded with the military health standard. In the semi-closed spaces,the mycetes counts were 5 950 cfu/m3 and 9 500 cfu/m3 in aisle and rooms respectively, significantly higher than those in control group (P

Objective To observe the effect of air disinfection with chlorine dioxide(ClO2)in the saps and determine the concentration change in order to ensure the safety for people to enter the saps.Methods The disinfection was done at the concentration of 1 000 mg/L and the spray dose of 10 ml/m3 and then to count the total bacteria and fungi with the cascade impactors in the saps before and after air disinfection and to monitor the concentration of ClO2 with the air ClO2 monitor(iTX).Results The 94.6% of the total bacteria and 92.1% of the fungi died in 30 minutes after disinfection.The concentration of ClO2 in the air decreased from 10 mg/m3 to 0.8 mg/m3 81 minutes later and to 0.3 mg/m3 96 minutes later,after 120 minutes,it was 0 mg/m3.Conclusion The air disinfection effect of ClO2 used at the dose of 10 ml/m3 and the concentration of 1 000 mg/L is satisfactory.96 minutes after disinfection,the concentration of ClO2 is safe for human health.

Objective: To investigate the effects of exogenous hormones, salicylic acid, and methyl jasmonate on suspension cell growth and anthraquinone production of Morinda citrifolia. Methods: After cell suspension lines were established, the cell suspension cultures were treated with exogenous hormones, salicylic acid, and methyl jasmonate, respectively. Then the specific growth rate and anthraquinone production were determined. Results: Exogenous hormone NAA and KT had a significant effect on suspension cell growth and anthraquinone production of M. citrifolia. The optimal medium for the cell suspension culture was B5 + 2 mg/L NAA and 0.1 mg/L KT. The anthraquinone content was up to 588.34 and 595.49 mg/L respectively in the presence of 200 μmol/L salicylic acid and 50 μmol/L methyl jasmonate on day 9, and increased by 17.05% and 18.47% respectively more than those in the control group. Conclusion: The optimum ratio of exogenous hormones combined with exogenous induction of a certain concentration of salicylic acid and methyl jasmonate could promote the production of anthraquinone.

[Abstract] Objective To investigate the relationship between plasma N-terminal pro-brain natriuretic peptide (NT-pro-BNP), P-selectin (PS) and type 2 diabetes mellitus (T2DM) patients with acute coronary syndrome (ACS). Methods Two hundred and twenty-eight patients with chest pain, admitted in the Department of Cardiology of Langfang Traditional Chinese Medicine Hospital and the Affiliated Hospital of North China University of Science and Technology from July 2017 to April 2018, were selected in present study, including 32 patients with T2DM, 124 patients with ACS, and 72 patients with T2DM complicated with ACS (DA group). ELISA was performed to detect the levels of plasma NT-pro-BNP and PS, and venous blood was taken on an empty stomach to complete a general biochemical project. Based on the results of coronary angiography performed by using Judkins method, the Gensini score was used to evaluate the degree of coronary stenosis. The general clinical data of the 3 groups were compared, and logistic regression was performed to analyze the risk factors for ACS in patients with T2DM. Results No statistical difference existed in gender, history of hypertension, smoking, body mass index, age, and creatinine among the three groups; The levels of low-density lipoprotein cholesterol and triglyceride were higher in DA group [(3.16±0.98)mmol/L and (2.21±1.36)mmol/L] than in T2DM and ACS group [(2.83±0.91)mmol/L, (1.65±1.05)mmol/L and (2.84±0.92)mmol/L, (1.68±0.97)mmol/L] with significant difference (P<0.05). The left ventricular ejection fraction was lower in DA group (58.97±7.35)% than in T2DM and ACS groups [(63.48±7.37)% and (61.26±7.68)%, respectively] with statistically significant difference (P<0.01). The PS was higher in DA group (48.30±13.61)ng/L than in ACS group (38.87±9.12)ng/L, and in ACS group than in T2DM group (21.46±12.30)ng/L; The C-reactive protein was higher in DA group [(27.63±11.87)mg/L] than in ACS group (20.21±9.32)mg/L, and in ACS group than in T2DM group [(10.30±4.22)mg/L]; The NT-pro-BNP M(Q1, Q3) was higher in DA group [419(154, 1350)pg/ml] than in ACS group [120(43, 416)pg/ml], and in ACS group than in T2DM group [22(12, 54)pg/ml]; The Gensini scores was higher in DA group (138.39±88.31) than in ACS group (82.12±63.08), and in ACS group than in T2DM group (39.98±32.12), all the differences listed above were statistically significant (P<0.01). It had been confirmed by multivariate logistic regression analysis that the levels of PS and high-sensitivity C-reactive protein were the risk factors for ACS in patients with DM, their OR estimates were 1.138 (95%CI 1.089-1.990, P<0.01) and 1.656 (95%CI 1.189~2.307, P<0.01), respectively. Conclusion High levels of PS and high-sensitivity C-reactive protein are the independent risk factors for ACS in patients with T2DM. NT-pro-BNP was not associated with ACS in patients with T2DM.

With the development of tissue engineering,the bone tissue engineering is developing rapidly. Engineering hone typically uses an artificial extracellular matrix (scaffold),osteoblasts or progenitors,and os- teoinductive factors which promote cell attachment,differentiation,and mineralized bone formation.Highly porous scaffolds play a critical role in cell seeding,proliferation,and new 3D-tissue formation.A variety of biodegradable polymer materials and scaffolding fabrication techniques for engineering bone have been developed over the past decade.This article reviews the scaffold design and fabrication methods tor engineering bone to analyze their ad- vantages and limitations.Various architectural parameters of scaffolds important for bone tissue engineering (e.g. porosity,pore size,interconnectivity) are discussed.
