OBJECTIVE:To explore the effects of atorvastatin combined with allopurinol on blood lipid and blood uric acid in patients with hyperlipidemia and hyperuricemia. METHODS:90 patients with hyperlipidemia and hyperuricemia were randomly di-vided into group A,group B and group C. Group A was orally given 0.1 g Allopurinol tablet,once a day+30 mg Atorvastatin calci-um tablet,once a day. Group B was given Atorvastatin calcium tablet(the same dose with group A). Group C was given Allopuri-nol tablet (the same dose with group A). The treatment course for all groups was 4 weeks. TG,TC,LDL,HDL,UA,BUN, ALT and CK before and after treatment,and incidence of adverse reactions in all groups were observed. RESULTS:After treat-ment,TG,TC and LDL in all groups were significantly lower than before,group A and B were lower than group C,the differenc-es were statistically significant (P<0.05);UA in all groups was significantly lower than before,group A and B were lower than group C,group A was lower than group B,the differences were statistically significant(P<0.05);ALT in group A and B,CK in all groups and BUN levels in group A and group C were significantly higher than before,CK in group A and group B higher than group C,group A was higher than group B,the differences were statistically significant(P<0.05). And there was no significant dif-ference in the incidence of adverse reactions among all groups(P>0.05). CONCLUSIONS:Atorvastatin combined with allopurinol can significantly reduce the blood lipid and blood uric acid levels of patients,with good safety.

In 2010, the artificial synthesis of Mycoplasma mycoides triggers the new era of synthetic biology. This great breakthrough is achieved mainly thanks to the powerful DNA recombinant ability of yeast. In recent years, except for the methods used for large DNA assembly on the basis of in vivo homologous recombination, various different DNA assembly methods in vitro, based on the concept of DNA ligation or polymerization, have also been developed, such as Biobrick\BglBrick, SLIC and Gibson one-step assembly. Application of these new technologies has greatly accelerated the construction of synthetic part libraries, biosynthetic pathway and even microbial chromosomes. In fact, all DNA assembly methods are derived from the combinations of DNA joining and organizational schemes. This review describes the brief introduction of the main in vivo and in vitro DNA assembly protocols developed so for, which will benefit the construction of different types of synthetic functional devices and also biosynthetic pathways in the research of synthetic biology in China.

OBJECTIVETo investigate the salvage therapy for a child with refractory and ( or) repeatedly-relapsed Langerhans cell histiocytosis.

METHODData of a patient with Langerhans cell histiocytosis whose disease relapsed repeatedly treated with cladribine was collected and analyzed and the related literature was reviewed.

RESULTThe initial symptoms developed 3 months after his birth, multiple systems (skin, skeleton, lung, liver) were involved; he was sequentially treated with LCH-III-Group I, JLSG-96, DAL-HX90 chemotherapeutic regimens. The patient got relapses for more than 3 times, but the disease got completely controlled after being treated with cladribine when the patient was 6 years old. The dosage was 10 mg/(m2 · d) for 4 days, and one course lasted for 28 days, the third to fifth courses of treatment used Arac in combination, the whole treating time lasted for 5 months. The patient remained in persistent remission for 8 months since discontinuation of treatment. "Langerhans cell histiocytosis" "refractory" "cladribine" were used as the key words to search in the data bases CNKI, Wanfangdata and Pubmed, 11 articles were picked. According to the literature, the effective rate of cladribine in treatment of repeatedly relapsing Langerhans cell histiocytosis was 44%-100%, with a good response of 22%-86%, the dose was 5-13 mg/(m2 · d). The main side effects were hematological system damages and infection.

CONCLUSIONThe effect of commonly used chemotherapeutic regimens is limited for children with refractory and (or) repeatedly-relapsed Langerhans cell histiocytosis and cladribine can be used as an alternative therapeutic option of the salvage therapy.

Objective To explore the effect of the cancer pain nursing team in standardized nursing inter-vention of pain in elderly cancer patients.Methods 76 patients in Department of Pain in our hospital were selected in our research.A random number table method was used to divide them into the control group and the observation group,with 38 cases in each group.Conventional treatment and nursing care was given to control group.The observa-tion group received routine treatment and nursing care by cancer pain nursing team,which the content of nursing was same,but the nursing method is different.Before and after the intervention,impact on pain intensity,adverse reactions and satisfaction for medical and nursing were compared between the two groups.Results Before nursing intervention, the pain score between the two groups had no statistically significant difference(P >0.05).After nursing interven-tion,pain score of the observation group was 1.5 (1,2)points,which was lower than 2(1,3)points in the control group,the observation group had better analgesic effect than the control group (Z = -4.385,P =0.000).The incidence rate of adverse reaction of the observation group was 13.16%,which was lower than 47.37% of the control group,the difference between the two groups was statistically significant(χ2 =10.537,P =0.001).The satisfaction for medical nursing process in the observation group was (9.74 ±0.45 )points,which was higher than (9.42 ± 0.76)points of the control group (t =2.213,P =0.030).Conclusion For senile cancer patients,the cancer pain nursing team could implement the standardized nursing intervention to relieve the body pain level,reduce the adverse drug reactions,so as to improve the quality of life.

SUMMARY We described 1 case of autoimmune lymphoproliferative syndrome ( ALPS) , first diagnosed in our hospital, and reviewed the recent literature. The 11-month old male patient presented with a histo-ry of splenomegaly and hepatomegaly since 1 month after birth. He suffered recurrent infectious diseases including cytomegalovirus infection, parvovirus B19 infection and chronic diarrhea disease. Besides, his symptoms included hemolytic anemia and thrombocytopenia. The laboratory abnormality indicated an ex-panded population of alpha/beta double-negative T cells (DNTs) (27. 18% of lymphocytes, 35. 16% of CD3 + T lymphocytes) in peripheral blood, and autoantibodies including antinuclear antibody, double-stranded DNA and rheumatic factor were positive. Hyper gamma globulinemia and positive direct Coombs tests were seen in the patient. His parents were both healthy and denied autoimmune diseases. We iden-tified a heterozygous point mutation in exon 3 of the FAS gene carrying c. 309 A>C, resulting in a single base pair substitution in exon 3 of FAS gene which changed the codon of Arg103 to Ser103 . Unfortunate-ly, we were unable to obtain the gene results of the child' s parents. The patient was treated with glu-cocorticoids in our hospital and with mycophenolatemofetil in other hospital. And we were informed that his anemia condition relieved through the telephone follow-up, but he still suffered recurrent infections, hepatomegaly and splenomegaly still existed. As we all know ALPS is characterized by defective lympho-cyte apoptosis, and thus cause lymphoproliferative disease and autoimmune disease, and increase the risk of lymphoma. It is more likely to be misdiagnosed as other diseases. ALPS should be suspected in the case of chronic lymphadenopathy, splenomegaly and autoimmune features. Flow cytometry approach is helpful for the diagnosis. Immunosuppressive drugs are the necessary treatment.
