Leptin as a polypeptide has a wide range of biologic effects, which can regulate appetite and energy metabolism common with leptin receptor. Recent studies found that leptin was related with tumor formation and development, which contribute to tumor progression by increasing angiogenesis, stimulates cell proliferation, adhesion and invasion through multiple channels.

Aim To establish an ideal two-dimensional polyacrylamide gel electrophoresis( 2-DE) method for serum proteomic research. Methods The 2-DE experiment of serum was opti-mized by adjusting the conditions of sample pretreatment and silver nitrate staining. Results An ideal 2-DE experiment method with higher repetition was established. The number of protein spots and the resolution were both increased,and this method was compatible with MS analysis. Conclusion After the adjustments and optimizations,an ideal method of 2-DE technique for serum is established,which has a high reference value for the relevant researches,and lays an experimental foundation for the search,analysis as well as identification of the disease related proteins in serum.

Objective To explore curative effects of coracolavicar ligament reconstructed with artificical tendon on treatment of complete acromioclavicular joint dislocation.Methods 32 patients with complete acromioclavicular joint dislocation received artificial tendon graft, 19 cases of whose implanted flexible carbonfiber tendon,and the others were treated with human-hair keratin artificial tendon (HHKAT). All patients were given bu internal fixation with Kirschner pins for 6 weeks after the operation.Results Fellowed-up for 4 months to 30 months showed the acromiclavicular join reduction and recovery of the anatomical relation of acromioclavicular joint checked by X-rayrecovered. According to karlsson scores, 21 cases graded excellent, 10 cases good and only one case bad, the excellent and good rate of recovery was 96 9%.Conclutions With the internal fixation with Kirschner pins in short term,and plus artificial tendon reconstructing coracoclavicalar ligament for patients with complete acromioclavicular joint dislocation, which had a little wound and a good curative effect, was easy to be performed and have worth in clinical application.

Background The ubiquitin-proteasome pathway(UPP)involves 80%-90% degradation of all in- tracellular proteins.Both ubiquitin and rat component 3 of proteasome(RC3)are hence considered to be central me- diators for cell biology.Objective To evaluate the effect of simvastatin on neointimal hyperplasia and the expres- sion of ubiquitin and rat component 3 of proteasome(RC3)after balloon injury in carotid artery.Methods Thirty- two male SD rats were randomly to receive,low dose(0.4 mg/ng,n=8),or moderate(4 mg/ng,n=8),or high- dose(40 mg/ng,n=8)of simvastatin treatment for 28 days.Common carotid aortic artery was injuried rat ballon. The ratio of intima-media(I/M)thickness was determined.The expression level of ubiquitin and RC3 mRNA were assessed by RT-PCR.The expression level of ubiquitin protein was examined with immunohistochemistry. Results Simvastatin inhibited the expression of ubiquitin and RC3 mRNA and ubiquitin protein in dose dependent manner.The intima-media ratio(-50.2 %)and the expression of ubiquitin(-60.3 %)and RC3 mRNA and ubiq- uitin protein(-60.5 %)was reduced by the high dose simvastatin [40 mg/(kg?d)](P

Objective To discuss medicine using regularity of TCM treatment for hypothyroidism. Methods Articles in the CNKI from Jan. 2000 to Dec. 2013 were searched. Articles about TCM treatment for hypothyroidism were screened for the establishment of database. Microsoft Excel was used to analyze the frequency of main medicine, composing principle, and combination of new medicine in the articles. Results Totally 150 cases of prescriptions about hypothyroidism were screened, which involved 178 Chinese herbal medicines. Poria in the prescriptions appears with the highest frequency;Atractylodis Macrocephalae Rhizoma and Poria have the highest frequency of medicinal pair. 14 core combinations and 7 new combinations were obtained through evolution. Conclusion Most doctors’ TCM treatment for hypothyroidism in CNKI is to replenish qi to invigorate the spleen, warm the kidney to tonify yang, and excrete water and dampness.

OBJECTIVE:To provide reference for the realization of normalization and standardization of quality control and management of Pharmacy intravenous admixture service(PIVAS). METHODS:The management and effectiveness of PIVAS quali-ty control in our hospital were introduced from aspects of the establishment of internal quality control system,the key indicators and effects of quality control. RESULTS:According to checking items from aspects of examining once in a month,on prescription checking,preparation,infection control,equipments,drugs,consumable materials,sanitation;holding 1 monthly quality control reviews;and analyzing unqualified indexes and existing security risks,the quality control of PIVAS had achieved good results. The qualified percentage of quality control index was increased from 84%(Jan. 2016)to 90%(Jun. 2016),error rate in the same peri-od was decreased from 0.579‰ to 0.099‰. CONCLUSIONS:Developing quality control of the implementation of detailed quality control key indexes for the whole process of intravenous infusion in PIVAS can effectively regulate the position working process,re-duce preparation error and ensure the quality of infusion preparation.

Objective To investigate the incidence of left-sided portal hypertension (LSPH) in chronic pancreatitis (CP) and other accompany conditions of CP and explore the diagnostic value of LSPH in chronic pancreatitis.Methods The clinical,pathological and imaging data of 125 CP patients received at least two imaging examination were retrospectively analyzed.The rates of abnormal pathologic findings,abnormal imaging findings and accompanying LSPH in CP were analyzed.The data were analyzed by chi-square test.Results Among 125 CP patients,29.6％ (37/125) received three or more than three kinds of imaging examinations.The pathological detection rates of pancreatic calcification or lithiasis,pancreatic ductal lesion,abnormal pancreatic morphology,pancreatic lesion and LSPH were 58.4％ (73/125),60.8％ (76/125),35.2％ (44/125),48.8％ (61/125) and 24.8％ (31/125),respectively.The sensitivities of imaging examination in those lesions were 68.5 ％(50/73),96.1％ (73/76),95.5％ (42/44),95.1％ (58/61) and 90.3％ (28/31),respectively.The detection rates of pancreatic calcification or lithiasis and pancreatic ductal lesion in pathological examination were significantly higher than those of the others,and differences were statistically significant (x2=33.764 and 37.932,both P＜0.01).The sensitivity of imaging examination in pancreatic calcification or lithiasis was lower than those of the others and the differences were statistically significant (x2 =36.526,P＜0.01).Among 125 CP patients with 223 pancreatic lesions detected by imaging examination,the rates of patients with 0,1,2,3,4 lesions accounted for pancreatic were 5.6％ (7/125),40.0％ (50/125),28.8％ (36/125),21.6％ (27/125) and 4.0％ (5/125),respectively.Of patients with pancreatic calcification or lithiasis,pancreatic ductal lesions,abnormal pancreatic morphology and pancreatic lesions detected by pathological examination,there were 23.7 ％(17/73),20.0％ (15/76),22.6％ (10/44) and 27.9％ (17/61) cases accompanied with LSPH,there was no difference between these groups (x2 =1.262,P=0.738).Conclusion LSPH may be a reference for CP diagnosis by imaging examination.
