Galetins is a family of endogenus lectins with highly affinity for polysaccharide containing β-galactosides residues.It is involved in cell growth and differentiation,cell adhesion,cell signal transduction and apoptosis.In recent years,many studies have shown that galectin plays an important role in the development and occurrence of gynecological malignancy.It has been an important evidence for diagnosis of progress of malignancy.

Thyroid nodules are common diseases with increasing incidence in recent years.Patients undergoing thyroid surgery are increasing.Based on the current national guidelines,this article analyzes the issue of insufficient treatment and over treatment in the process of surgical treatment for thyroid nodules,conducive to individualized and standardized treatment.

Objective To investigate the adsorption mechanism of amorphous aluminum hydroxyphosphate sulfate(AAHS)adjuvant and aluminum hydroxide adjuvant on recombinant hepatitis B surface antigen(HBsAg) and the effect of differentadsorption rates on the titer of hepatitis B.MethodsThe Langmuir adsorption equation was used to calculate the maximumadsorption capacity of HBsAg on the surface of AAHS and aluminum hydroxide adjuvants at different concentrations ofsodium chloride(NaCl) and ethylene glycol. Combined with the influence of different concentrations of phosphate on theadsorption effect of HBsAg, the main forces affecting the adsorption of HBsAg and two aluminum adjuvants were analyzed,and the difference between the two adjuvants was also compared. ED_(50)was used to evaluate the immune effect of sampleswith different phosphate concentrations, and the relationship between different adsorption rates and titers was analyzed.ResultsDifferent concentrations of NaCl and ethylene glycol did not affect the adsorption rate of HBsAg, and the adsorptionrate decreased with the increase of phosphate concentration. The titer of samples with lower adsorption rate was still withinthe qualified standard range.ConclusionHBsAg is mainly adsorbed on the surface of AAHS and aluminum hydroxide adju-vants through ligand exchange, and hepatitis B titer may not require high antigen adsorption rate in vitro.

Protein-energy wasting is a common complication in patients with chronic kidney disease and also an independent risk factor for poor prognosis.The pathogenesy and diagnosis of protein-energy wasting in children with chronic kidney disease,assessment of nutritional status were summarized.

Helicobacter pylori infection is a common gastrointestinal infection,which is a major cause of chronic gastritis,peptic ulcer,stomach cancer and gastric mucosa-associated lymphoid tissue lymphoma and other diseases.In recent years,many studies show that Helicobacter pylori infection is closely related with many diseases,which may cause the retardation of children development and affect blood lipids and glucose metabolism.Helicobacter pylori infection may also lead to chronic inflammatory process,results in a large number of cytokines and play an important role in artery atherosclerosis.This paper reviews on the correlation between Helicobacter pylori infection and metabolic diseases and its mechanism as well.

AIM:To determine whether imperatorin would enhance the effect of doxorubicin therapy on cervi -cal cancer in vitro.METHODS:The viability of HeLa cells treated with imperatorin and doxorubicin was determined by MTT assay in vitro.The expression of Bcl-2 protein family ( Mcl-1, Bcl-2, Bcl-xL, Bad and Bax ) in HeLa cells treated with imperatorin and doxorubicin was evaluated by Western blot analysis .The apoptosis and mitochondrial membrane poten-tial (ΔΨm ) in the HeLa cells treated with imperatorin and doxorubicin were analyzed by flow cytometry .A Mcl-1 expres-sion vector was constructed , and its role in the cytotoxicity of imperatorin plus doxorubicin to HeLa cells was detected by MTT assay.RESULTS: Addition of imperatorin significantly enhanced the cytotoxicity of doxorubicin to HeLa cells in vitro.Mcl-1 expression was down-regulated by imperatorin but was not influenced by doxorubicin in the HeLa cells .A com-bination of imperatorin and doxorubicin induced apoptosis and ΔΨm collapse more significantly compared with the treatment with imperatorin or doxorubicin alone .Furthermore, the imperatorin-induced sensitization for doxorubicin cytotoxicity to HeLa cells was abolished by the transfection with Mcl-1 expression plasmid .CONCLUSION:The combination of doxoru-bicin with imperatorin enhances the antitumor effect of doxorubicin on cervical cancer cells via targeting Mcl -1.

Protein-energy wasting is a common complication in patients with chronic kidney disease and also an independent risk factor for poor prognosis.The progress of diagnosis and treatment for protein-energy wasting in children with chronic kidney disease were summarized.

duodenum, respectively. Conclusion The absorption of tetrandrine is first-order process with passive diffusion mechanism. Tetrandrine is well absorbed at all segments of intestine in rats.

0.05). CONCLUSION: Cefepime is a safe and effective agent in treatment of low-respiratory tract infection like ceftazidme.
