Objective To observe the effect of S-adenosyl-L-methionine(SAMe) in treatment of jaundice in newborns and its mechanism.Methods Two hundred and two newborn infants with jaundice were treated with SAMe,76 cases in control group treated with phototherapy and liver enzyme induction elixir;SAMe 30-60 mg/(kg?d) were added to 202 cases intravenously in treatment group.The total biliorubin(T-BILI),direct bilinrubin(D-BILI) and indirect bilinrubin(I-BILI) were dynamically detected.Results Six days after treatment,the skin jaundice index in treatment group decreased remarkably.T-BILI,D-BILI and I-BILI decreased significantly.The curing effectiveness was higher in treatment group than that in control group.The number of applicating blood products and albumin,and blood produets/albumin were decreased in treatment group than those in control group.In those who used glucose to dissolve the SAMe 2.68% had blood-vessel phlebitis.Conclusions SAMe can efficiently quicken the retrogression of jaundice in newborns.It can reduce the use of blood products.It is a reliable and safe drug to treat jaundice in newborns.

To obtain the key genes for chlorogenic acid biosynthesis of Lonicera hypoglauca, four new genes ware obtained from the our dataset of L. hypoglauca. And we also predicted the structure and function of LHPAL4, LHHCT1 , LHHCT2 and LHHCT3 proteins. The phylogenetic tree showed that LHPAL4 was closely related with LHPAL1, LHHCT1 was closely related with LHHCT3, LHHCT2 clustered into a single group. By Real-time PCR to detect the gene expressed level in different organs of L. hypoglauca, we found that the transcripted level of LHPAL4, LHHCT1 and LHHCT3 was the highest in defeat flowers, and the transcripted level of LHHCT2 was the highest in leaves. These result provided a basis to further analysis the mechanism of active ingredients in different organs, as well as the element for in vitro biosynthesis of active ingredients.

Objective To establish a rapid, sensitive and selective liquid chromatography-tandem mass spectrometry (LC-MS/MS) method for the determination of acyclovir (the metabolite of valacyclovir hydrochloride) in human plasma. Methods After addition of ganciclovir as internal standard (IS), plasma samples were prepared by one-step protein precipitation using acetonitrile as precipitant, followed by an isocratic elution with 0.1% formic acid 3.5μm) column. Detection was performed on a triple-quadrupole mass spectrometer utilizing electrospray ionization (ESI) interface operating in positive ion and selected reaction monitoring (SRM) mode with the precursor to product ion transitions m/z 226.2→152.1 for acyclovir and m/z 256.2→152.1 for the IS. Results The analytical results demonstrated a good linearity over the ranges from 0.005 to 4μg/mL (r=0.9999) for valacyclovir hydrochloride. The relative standard deviations (RSD) of intra-batch and inter-batch were less than 4.06% and 9.23%, respectively. The limit of detection and lower limit of quantification in human plasma were 2ng/mL and 5ng/mL, respectively. Conclusion The method was simple, sensitive, accurate and reproducible and has been successfully applied to a bioequivalence study of valacyclovir hydrochloride capsules in Chinese healthy male volunteers.

ObjectiveTo compare the performance of color Doppler utrasonography (CDUS) alone,magnetic resonance imagine (MRI) alone, and the combination of the two in the diagnosis of thyroid carcinona (TC). MethodsCDUS and MRI results of 54 focuses of carcinoma in 45 cases diagnosed as TC by postoperative pathological results were reviewed. The sensitivity of CDUS, MRI, and the combination of the two in the diagnosis of TC was compared. ResultsThe sensitivity of CDUS and MRI was 77.78％ (42/54)and 81.48％(44/54) respectively. The difference had no statistical significance (P ＞ 0.05 ). The specificity of CDUS and MRI was 88.17％ and 92.47％ respectively, the positive predictive value was 79.25％ and 86.27％ respectively,and the negative predictive value was 87.23％ and 89.58％ respectively. The sensitivity of the combination of CDUS and MRI was 94.44％ (51/54). The difference between the combination and CDUS or MRI alone had statistical significance( P ＜0.05). ConclusionsCDUS has higher detection rate than MRI in microcalcification of TC focus. However, MRI can show more clearly of the peripheral invasion and cervical lymph node metastasis.The combination of the two can improve the accuracy of TC diagnosis.

· AlM:To analyze the association between the macular thickness and emmetropic, low myopic, moderate myopic and highly myopic eyes.
·METHODS:The 276 teenagers (276 eyes) between 18~28 years treated in our hospital from January, 2013 to May, 2014 were selected, whose corrective visual acuity was≥1.0 and intraocular preasure was ≤21mmHg and who were willing to participate in this research.Forty-nine emmetropic, 72 low myopic, 104 moderate myopic and 51 highly myopic eyes were measured by optical coherence tomography ( OCT ) to detect the central subfield thickness, bitamporal, superior, lateral and inferior region thickness of inner and outer region, average thickness of retinal macula, foveal thickness and retinal volume.The thickness of different parts of macula lutea was measured and statistically compared among emmetropic, low myopic, moderate myopic and highly myopic eyes.
· RESULTS: The central subfield thickness of emmetropic, low myopic, moderate myopic and highly myopic eyes were (225.38±20.97), (230.97±19.15), (227.01±16.92), (231.91 ±18.97 )μm. The average thickness of retinal macula, of emmetropic, low myopic, moderate myopic and highly myopic eyes were (280.92±12.71), (278.15± 11.90), (270.05±12.07), (267.93±11.08) μm.There were no significant differences of center thickness (F=1.253, P=0.291) and central subfield thickness ( F=1.034, P=0.378) between emmetropic, low myopic, moderate myopic and highly myopic eyes.The macular thickness of inner and outer region in moderate myopic eyes was significantly less than that in emmetropic eyes, and there was significant difference (P<0.05).Comparison between low myopic, moderate myopic and highly myopic eyes was carried out and macular thickness of all regions of inner and outer region in moderate myopic group was significantly increased, and there was significant difference (P<0.05).There was no significant difference when compared with the macular thickness of inner and outer region of the highly myopic group (P>0.05).
· CONCLUSlON: ln low myopic eyes of teenagers, the center macular thickness do not become thinner. However, the macular thickness of inner and outer region is thinner than that of emmetropic eyes.Furthermore, with the increase of the degree of the myopia, the amount of macular thinner gradually decreases from outer region to inner region.
