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.

OBJECTIVETo study the effect of Shumai Capsule (SMC) on angiogenesis and expression of relevant growth factor in rats with myocardial ischemia (MI).

METHODSModel rats of MI were duplicated and treated with SMC (SMC group), bFGF + calparine (positive control group) and normal saline (model group) respectively. Besides, a sham-operative group was set up and treated with normal saline. The rats were sacrificed in batches at the time after being medicated for 1, 2 and 4 weeks, for determining von Willebrand factor (vWF) and vascular endothelial growth factor (VEGF) protein expression in ischemic myocardium by immuno-histochemical staining, myocardial micro-vessel density (MVD) using digital analysis system, and the gene expression of VEGF by quantitative real-time PCR.

RESULTSCompared with the sham-operative group and the model group, levels of MVD, protein and gene expression of VEGF in the SMC group were higher respectively at three time segments (all P <0.01), but showed insignificant difference to those in the positive control group.

CONCLUSIONSMC could promote angiogenesis in ischemic myocardium of rats, the up-regulation on VEGF mRNA and protein expression might be one of the potential mechanisms of SMC in promoting angiogenesis.

The genomes of umbraviruses do not encode a coat protein, and thus no conventional virus particles are formed in infected plants. Umbraviruses are always coinfected with an assistor virus, which is always a member of the family Luteoviridae, to cause most devastating diseases in some areas. The epidemiology of the umbra-virus-caused disease is largely depended on aphid transmission. The symptomology, occurrence, characteristics of the causal agents, disease control of carrot motley dwarf, groundnut rosette and tobacco bushy top were reviewed detailedly in this article.

The cholesterol oxidase producing strain Brevibacterium sp.DGCDC-82 was treated with NTG (1 mg/mL)under ultrasonicztion(200 W,50 kHz).A red mutant named Brevibacterium sp.DGCCN-25 showed higher and stable production of cholesterol oxidase was obtained.The enzyme activity was increased by 140%,it is 1.24 U/mL.Then dealed with DGCCN-25 using the same method,two revertants were obtained,one was white and the other was rose pink.The enzyme activity of two revertants was obvious decrease,they are 0.17 U/mL and 0.69 U/mL.The results showed the positive correlation between COD acticity and red pigment producing by Brevibacterium sp..The relativity model can be used as a method of screening for mutation and directed evolution.

Abstract: Objective　To investigate the pollution of paralytic shellfish poisons (PSP) in shellfish sold in Hainan Province from 2018 to 2021. Methods　From 2018 to 2021, the content of 10 paralytic shellfish poisons including saxitoxin (STX), neosaxitoxin (neoSTX), gonyautoxins 1 (GTX1), gonyautoxins 2 (GTX2), gonyautoxins 3 (GTX3), gonyautoxins 4 (GTX4), gonyautoxins 5 (GTX5), decarbamoylsaxitoxin (dcSTX), decarbamoylgonyau toxins 2 (dcGTX2) and decarbamoylgonyau toxins 3 (dcGTX3) in 7 kinds of shellfish commonly sold in 13 cities and counties in Hainan province was analyzed. Results　The detection rate of PSP in 360 shellfish samples was 10.3%. Among them, the highest detection rate of STX was 5.83%, followed by GTX2 detection rate of 4.17%; the detection rate of neoSTX and GTX3 were both 1.67%; the detection rate of GTX1 was 1.39%. None of the five PSP, GTX4, GTX5, dcSTX, dcGTX2 and dcGTX3, were detected. Four types of PSP were detected in fanscallops, two were detected in oysters, mussels and Scapharca subcrenata, only one was detected in scallops, and no toxin contamination was detected in clams and razor clams. A single sample of fanscallops detected a maximum of 4 PSP, and a single sample of oysters, scallops, mussels and Scapharca subcrenata detected a maximum of 1 PSP. The equivalence of PSP in all samples was ND-155.6 μg/kg.The annual detection rate of PSP from high to low was: 20.0% in 2020, 15.6% in 2019, 5.3% in 2018, and 2.0% in 2021, and none of the samples tested exceeded the standard. Continuously detectable STX in 2018-2020, all PSP that could be detected in 2018 were STX. In 2019, in addition to STX detected in scallops and Scapharca subcrenata, neoSTX was also detected in oysters, mussels and Scapharca subcrenata. In 2020, PSP was only detected from scallops, and GTX2 could be detected in all positive specimens, while 5 STX, 5 GTX1 and 6 GTX3 were detected. Only GTX2 detected from scallops in 2021. STX was detected in shellfish sold in 12 cities and counties, GTX2 can be detected in 10 cities and counties, neoSTX can be detected in 5 cities and counties, GTX1 and GTX2 were detected in 4 cities and counties respectively. Shellfish sold in Wenchang and Lingshui markets can detect 5 types of PSP. Conclusion　Some types of shellfish on the market in Hainan are contaminated with some kind of PSP pollution risks, and it is necessary to strengthen the supervision of PSP in marketed shellfish.

Objective To discuss the clinical efficacy and nursing methods of hemoperfusion (HP) in the treatment of severe organic phosphorus pesticide poisoning (AOPP). Methods 48 cases of severe organic phosphorus pesfcide poisoning were randomly divided into the conventional therapy group (22 cases) and the blood perfasion group (26 cases). The conventional therapy group received stomach lavage, liquid supplement, diuresis, catharsis, and drug therapies of atropine and pralidoxime. The bemoperfusion group received the treatment of blood perfusion for 1 ～ 3 times on the basis of the conventional treatments and the corresponding observation and nursing. Results The time of coma to sober and the hospitalization time were shorter, the total amount of atropine was less and the cure rate was higher in the hemoperfusion group compared to those in the conventional therapy group (P < 0.05). Conclusions The hemoperfusion in combination with conventional medical treatments is the most effective way to rescue severe organic phosphorus pesticide poisoning. The corresponding nursing should be given to the patients during the therapy.

Taking application of some isolation and purification technologies, such as solvent extraction, preliminary solvent isolation, column chromatographies over silica gel and Sephadex LH-20 gel and preparative HPLC, 10 compounds were obtained from Gynura nepalensis cultivated in the suburban area of Beijing. Their structures were identified by spectroscopic methods and comparison with literature as (3R) -3-hydroxy-β-ionone (1), (3S,5R, 6S, 7E) -5, 6-epoxy-3-hydroxy-7-megastigmen-9-one (2), (+) -boscialin (3), 3, 6-trans-3-hydroxy-α-ionone (4), 3, 6-cis-3-hydroxy-α-ionone (5), 3, 4-cis-3, 4-dihydroxy-β-ionone (6), ethyl caffeate (7), loliolide (8), 1H-indole-3-carbaldehyde (9), and 3-(hydroxyacetyl)indole (10), respectively. All compounds were isolated from the title plant for the first time, and with compounds 1, 2, 4-7, 9 and 10 being isolated from Gynura species for the first time. Structurally, the above compounds 1-6 belong to C13 nor-sesquiterpenoids, sharing the same carbon skeleton of megastigmane. According to this study, they are one of major kinds of chemical constituents of Gynura nepalensis and have important reference value for the investigation on phytotaxonomy of this species.
