With the development of assisted reproductive technology , it brings the gospel to many infertility families , and it makes a new challenge to the moral and legal at the same time .Ministry of Health issued the notice on carrying out the special action to manage assisted reproductive technology .By thinking about the ethical and le-gal issues, this paper tried to explore a new response mode to advance the development of assisted reproductive technology and to ensure social harmony and stability .

Objective To investigate the expression of high mobility group A1 (HMGA1) in patients with lung squamous cancer and its clinical significance.Methods The expression of HMGA1 in 76 patients with lung squamous cancer (lung squamous cancer group) and 30 cases of control lung tissue (control group) was detected by SP method of immunohistochemistry and its correlation with clinical-pathological parameter was analyzed statistically.Results The positive expression rate of HMGA1 was 68.4％ (52/76)and 16.7％ (5/30) in lung squamous cancer group and control group respectively,and the difference was significant(P＜ 0.01).HMGA1 expression showed significant correlation with lymph metastasis and degree of differentiation in patients with lung squamous cancer (P ＜ 0.05).Conclusions The progression of lung squamous cancer may correlate with the increase of HMGA1 expression.It's promising for HMGA1 to become a new marker for diagnosis of lung squamous cancer.Clinical detecting of HMGA1 could help with prognosis and treatment-guiding of lung squamous cancer.

Toll-like receptors is a super-family of pathogen recognition-receptors discovered in recent years.During the process of ischemia-reperfusion, the Toll-like receptor 4 (TLR4) combines with lipopolysaccharide and many endogenous ligands such as high mobility group protein B1, heparan sulfate, and fibrinogen. Through the myeloid differentiation protein 88 -dependent and -independent signaling pathways, the products induce the release of inflammatory cytokine-mediated inflammatory response, leading to injuries. ω-3 polyunsaturated fatty acids, by inhibiting the signal pathway activation and target gene expression of TLR4, can influence the function of many immune cells and regulate the body's inflammatory response and immune function. This article reviews the function of TLR4 during ischemia-reperfusion injury and the possible interventional role of ω-3 polyunsaturated fatty acids.

OBJECTIVE:To study the relative bioavailability and pharmacokinetics of salbutamol sulfate orally disinte?grating tablets.METHODS:A single dose of8mg salbutamol sulfate orally disintegrating tablets or commercial salbutamol tablets was administered in a randomized crossover design in18volunteers and the plasma concentrations of salbutamol were determined by HPLC.The pharmacokinetic parameters were calculated with3p97pharmacokinetic program and the bioequiv?alency was evaluated.RESULTS:The concentration-time curve of two preparations fitted to two-compartment model.The peak plasma levels(C max )of salbutamol sulfate orally disintegrating tablet and commercial salbutamol sulfate tablet were(17.65?6.48)ng/ml and(16.60?6.21)ng/ml,respectively.The peak time(T max )were(1.92?1.18)h and(2.03?1.17)h and AUC 0～24 were(127.23?32.41)ng/(h?ml)and(131.42?37.73)ng/(h?ml),respectively.The relative bioavailability of salbu_ tamol sulfate orally disintegrating tablet was(99.32?15.58)%.CONCLUSION:The results of two one-side tests suggests that salbutamol sulfate orally disintegrating tablet is bioequivalent to the commercial salbutamol tablet.

OBJECTIVE: To study distribution and pharmacokinetics of gatifloxacin in ocular tissues of rabbit after ocular instillation.METHODS: The drug concentrations in ocular tissues were determined by HPLC after topical ocular instillation in rabbits;the pharmacokinetics parameters were figured out by 3p97 process. RESULTS: Results showed that the peak concentration of gatifloxacin in lacrimal fluid, cornea, aqueous humor, iris-ciliary body, lens and vitreous body 0.125h～1.0h after topical instillation were (1 115.75?151.04)?g/ml,(17.90?1.39)?g/g,(2.26?0.18)?g/ml,(9.12?0.33)?g/g,(1.07?0.13)?g/g and (0.77?0.04)?g/g respectively;t1/2? in various tissues were(2.14?0.33),(2.82?0.54),(3.33?0.43),(3.88?1.21),(3.89?1.43) and (3.14?0.43)h respectively;AUC(0→t) in various tissues were(541.77?69.73)(?g?h)/ml,51.31?3.04)(?g?h)/g,(6.55?0.45)(?g?h)/ml,(51.99?25.66)(?g?h)/g,(4.19?0.41)(?g?h)/g and (3.25?0.13)(?g?h)/g respectively.CONCLUSION:Gatifloxacin has a good permeability and high concentration in various intraocular tissues of rabbit after ocular instillation.

OBJECTIVE:To study pharmacokinetic parameters of melatonin tablet in beagle dogs.METHODS:A single oral dose of3mg melatonin tablet was given to6beagle dogs,drug concentrations in plasma were determined by HPLC method,the pharmacokinetic parameters were calculated by3P97pharmacokinetic program.RESULTS:The concentration-time curves of melatonin fitted two compartment model in the beagle dogs.The t 1/2Ka 、t 1/2Ke 、t max 、C max 、CL and AUC (0～T) were(0.16?0.10)h、(1.21?0.52)h、(0.50?0.18)h、(11.27?3.77)ng/ml、(0.13?0.04)L/h and(25.23?7.71)(ng?h)/ml re-spectively.CONCLUSION:It is rapid to absorb melatonin and initiate sleep in beagle dogs,but it's hold-time is short.

Carbamazepine ( CBZ ) serum and salivary concentration and toxic and side reactions were studied in 60 epilepsy patients. The propriate CBZ serum concentration was l7~38?mol/L, salivary concentration was 4~13?mol/L. The toxic and side reactions were correlated with serum level, there were different toxic symptoms when CBZ levels were in therapeutic range. When CBZ serum concen tration was higher than 38~51 ?mol/L, salivary concentration was higher than 14.8~17 ?mol/L, the toxic and side reactions were significant increased in our test patients.
