Receptor activity-modifying proteins(RAMPs) are type I transmembrane proteins,which are activity-modifying proteins of a variety of G-protein-coupled receptors(GPCRs).RAMPs are related to physiological and pathological phenomena such as neurological diseases,cardiovascular diseases,renal function,skeletal development and obesity,and of great significance for disease prevention,which are potential targets for the treatment of various diseases and also closely related to the prognosis of diseases.At present,there are few studies on proteins that may regulate the expression of RAMPs.This paper focuses on the sterol regulatory element-binding factor-2(SREBF-2) that may regulate the transcription and expression of RAMP3, and reviews the research progress of RAMPs in biology,pathology and pharmacology,providing a reference for the further research on RAMPs and the prevention and detection of related diseases.

Recurrence after surgery for common bile duct stones has not been solved properly,and recurrence of calculi often requires reoperation,which brings patients great pain and economic burden.Various risk factors may mediate the recurrence of common bile duct stones,including biliary tract infection,bile duct stenosis,cholangiectasis,cholestasis,Oddi sphincter dysfunction,abnormal bile composition,and surgical procedure.These risk factors are analyzed and related preventive measures are summarized.Current research findings show that prevention and treatment of risk factors for recurrence of calculi can reduce the recurrence rate of calculi and play an important role in preventing the recurrence of common bile duct stones.

Breast conserving surgery has become the first choice for the treatment of early breast cancer.However,the safety margin is still one of the important issues for surgeons in the implementation of breast conserving surgery.Because variety of clinical factors have some effects on the safety margin,at present,no consensus on safe margin of breast conserving surgery is reached,and the controversy still goes on.

Objective To summarize the perioperative experience of nursing the middle-aged and elderly patients of lumbar spinal stenosis and degenerative lumbar scoliosis treated with posterior or transforaminal lumbar interbody fusion. Methods Posterior or transforaminal lumbar interbody fusion was performed in 69 middle-aged and elderly patients with lumbar spinal stenosis and degenerative lumbar scoliosis. Nursing measures included evaluation and treatment of complications, preoperative guidance for surgical body position, and postoperative close monitoring, treatment of complications and functional exercises. Results The operation on all the 69 patients was smooth, with surgical time ranged from 3 to 7 hours and bleeding volume between 300~750 mL. Postoperatively, 9 patients suffered from CSF leaks, 3 ones had a screw loose by imageology, 2 did from pneumonia, 2 did from DVT, and 3 did from depression. After clinical management and nursing, all the patients were cured and discharged. Conclusions Meticulous clinical treatment and nursing of preoperative complications and instructions on body position are the foundation for successful surgeries. Postoperatively, close monitoring, management of the complications and the instruction on functional exercises are guarantees for the successful surgeries.

Herbal property theory of traditional Chinese medicines is the theoretical guidance on authentication of medicinal plants, herborization, preparation of herbal medicines for decoction and clinical application, with important theoretical value and prac- tical significance. Our research team proposed the "three-element" theory for herbal properties for the first time, conducted a study by using combined methods of philology, chemistry, pharmacology and mathematics, and then drew the research conclusion that herbal properties are defined as the chemical compositions-based comprehensive expression with complex and multi-level (positive/negative) biological effects in specific organism state. In this paper, researchers made a systematic mathematical analysis in four aspects--the correlation between herbal properties and chemical component factors, the correlation between herbal properties and organism state fac- tor, the correlation between herbal properties and biological effect factor and the integration study of the three elements, proposed future outlook, and provided reference to mathematical studies and mathematical analysis of herbal properties.

Objective To observe the interferon-γ(IFN-γ),interhukin-2(IL-2)levels of Th1 cytokine and IL-4、IL-10 levels of Th2 cytokine in serum and culture supernatants of splenic cells of the rats in the prevention of experimentaI autoimmune uveoretinitis(EAU)by oral tolerance. Methods 72 Lewis rats were randomly divided into EAU group,oral tolerance group(which including 10 μg、100 μg、1 mg、10 mg of S antigen group respectively)and control group,12 rats in each group.The animal model of EAU was induced by immunization with S antigen(50 μg)and Freund's complete adjuvant.Oral tolerance 10 μg、100μg、1 mg and 10 mg group were fed with 1 ml mixture of 10 μg、100μg、l mg、10 mg S antigen and 1 mg trypsin inhibitor respectively by intuhation,once the other day,totally 7 times,and then induced EAU according to above methods;control group was fed with 1 ml mixture of phosphate buffered saline and 1 mg trypsin inhibitor,once the other day,totally 7 times,and then induced EAU.The clinical manifestation of EAU in the eye were recorded,the eyeballs were enucleated at the peak of EAU,followed by pathological grading.Meanwhile the serum was colleced;splentic cells were separated and cultured to collect the supernatant.Cytokine levels of IFN-γ,IL-2,IL-4 and IL-10 in serum.cultured supernatant of splenic cells were determined by enzyme-linked immunosorbent assay(ELISA). Results Compared with EAU and control group,the levels of IFN-γ and IL-2(Th1 eytokine)in the serum in 100 μg and 1 mg group were decreased while the levels of IL-4 and IL-10(Th2 eytokine)were inereased,the diffefences were statistically significant(F=51.9,68.8,35.7,7.5,P＜0.01).Compared the levels of Th1 and Th2 cytokines in the serum in 10 μg,10 mg group with EAU and control group.the differences were not statistically significant.In 100 gg、1 mg group,the levels of IFN-γ and IL-2(Th1 cytokine)in the culture supernatant of splenic cells were decreased while the Ievels of IL-4 and IL-10(Th2 cytokine)were increased,compared with EAU and control group,the differences were statistically significant(F=57.1,15.6,33.1,167.7,P＜0.01).Compared the levels of Th1 and Th2 eytokine in the culture supernatant of splenic cells in 10 μg、10 mg groups with EAU and control group,the difference are not statistically significant. Conclusions In the process to prevent EAU by oral intake,the levels of IFN-γ and IL-2 (Th1 cytokine)were decrease while the levels of IL-4 and IL-10(Th2 cytokine).Oral administration with tOO high or low dose of the antigen can not prevent EAU as well as the cytokine levels do not change obviously.Cytokines has played an important role in the prevention of EAU.

Objective To observe the efficacy of the anti-tumor necrosis factor-α monoclonal antibody(TNF-α MCAb)in the treatment of experimental autoimmune uveoretinitis(EAU). Methods EAU animal models were induced by interphotoreceptor retinoid-binding protein(IRBP)R16 peptide with immunization.The rats were divided into 2 groups according to the injection times.TNF-α MCAh was administered intravenously on day 6 or 4,6 and 8 post-immunization respectively,and then to observe the clinical expression by slit-lamp microscope.Meanwhile,take the rats which did not accept TNF-α MCAb as conttol group.Delayed type hypersensitivity(DTH)responses were measured on day 13 postimmunization of IRBP R16;the rats were killed on day 14 post-immunization of IRBP R16,and then enucleated the eyes for histopathological examination.To detect the cytokine level of IFN-γ,IL-4 in serum and IFN-γ in aqueous humor by enzyme-liked immunosorbent assay(ELISA)on day 14 postinjection.The hyperplasia responses of antigen specific lymphocyte of draining lymph node cells were detected. Results The TNF-αMCAb group had mitigated ocular inflammation and decreased pathological grades compared with the control group;the IFN-γ concentrations in aqueous humor and serum were decreased,IL-4 was increased in serum;DTH responses were decreased;the hyperplasia responses of draining lymphocytes to IRBP R16 peptide were decreased,all the differences were statistically significant(P＜0.01).The rats accepted TNF-α MCAb thrice had much better curative effect than the rats injected once(P＜0.05). Conclusions Injection of TNF-α MCAb can inhibit ocular inflammation and specific immune cells of EAU remarkably and change the Th1/Th2 balance.Many times injections of TNF-α MCAb were more effective than once.
