Augmenter of liver regeneration(ALR)is a novel hepatic stimulator. Owing to its peculiar characteristic of gene structure and many kinds of biological functions, it is thought to be an important hepatotrophic factor. This review summarized the advance in ALR research in recent years including characteristics of ALR gene, molecular structure, physiochemical characteristics, biological functions and roles in liver injury.

Objective To identify and purify the allergens of Tyrophagus putrescentiae. Methods Tyrophagus putrescentiae extract was analyzed by SDS-PAGE and Western blotting, and was partially purified by DE52 anion-exchange chromatography and HiLoad 16, 60 Superdex 200 prep grade Size-exclusion chromatography. Results 23 bands were found after SDS-PAGE with comparative molecular weight (Mr) of 177 000, 118 000, 107 000, 70 000, 67 000, 60 000, 52 000, 45 000, 41 000, 40 000, 38 000, 37 000, 35 000, 27 000, 23 000, 22 000, 18 000, 17 000, 16 000, 15 000, 14 000, 13 00 and 12 000. Five allergens were detected by Western blotting with Mr 128 000, 67 000-70 000, 36 000-37 000, 18 000 and 16 000, respectively. The positive reaction rate of 3 allergens, with Mr 128 000, 67 000-70 000 and 36 000-37 000, were 100%, while that of other 2 allergens with Mr 18 000 and 16 000 was 77.8% and 44.4% respectively。The allergen with Mr 18 000 was purified by anion-exchange chromatography and Size-exclusion chromatography. Conclusion Four major allergens and one minor allergen from Tyrophagus putrescentiae have been identified.

Type Ⅱ innate lymphoid cells is an emerging family of innate lymphocytes mainly distributed in mucosal tissues such as the lungs,intestines,skin,etc.These cells are capable of producing Th2-type cytokines including IL-5 and IL-13 in response to IL-25 and IL-33.ILC2s has attracted much attention for its important roles in anti-infection immunity and allergic diseases in respiratory tract.Studies have shown that ILC2s represented a crucial source of Th2-type cytokines and could regulate the adaptive immune response in allergic airway diseases.Meanwhile,ILC2s was able to fulfill vital functions in parasite clearance, anti-virus infection and subsequent tissue repair.Therefore,research in ILC2s phenotype,development and function has great practical significance.This paper reviews the definition, classification, developmental regulation of ILC2s with a particular focus on its role in respiratory mucosal homeostasis and lung-related diseases.

Treated uroschesis due to spinal cord injury in 32 cases with acupuncture therapy (acupuncture group) and compared with Neostigmine injection (control group). In acupucture group, 10 cases got clinical recovery, 17 efficacy and 5 inefficacy, with an effective rate of 84.4%; among 32 cases in control group, 3 cases got clinical recovery, 15 efficacy and 14 inefficacy, the effecrive rate was 56.2%.

Objective To confirm the structure validity of questionnaire through a probe into latent factorial structure of the rear service personnel′s job satisfaction from polyclinics hospitals .Methods The questionnaire′s construct validity was estimated by ex‐ploratory factor analysis (EFA) and confirmatory factor analysis(CFA) .Results Exploratory factor analysis made the question‐naire including six factors which belonged to job satisfaction and occupation loyalty .Every factor had reasonable explanation and six factors remained 70 .306% information .Exploratory factor analysis of job satisfaction showed five factors ,explaining 70 .514% in‐formation .The confirmatory factor analysis model 1 and model 2 were conducted by LISREL8 .70 software .The results showed that X2 freedom degree was less than 5 .In addition to adjust the goodness of fit index was less than 0 .9 ,all other fit indices were greater than 0 .9 .At the same time ,SRMR and RMSEA were less than 0 .08 .Conclusion The results of exploratory factor analysis(EFA) and confirmatory factor analysis(CFA) both reveal that the questionnaire′s construct validity was good .

Objective To explore the feasibility and efficiency of laparoscopic surgery for the treatment of acute biliary pancreatitis (ABP) at early stage. Methods From January 2003 to June 2006, 18 patients with ABP received laparoscopic surgeries, including laparoscopic cholecystectomy (LC) in 3, LC combined with laparoscopic common bile duct exploration (LCBDE) in 9, LC combined with opening of the pancreatic capsule for drainage in 5, and LC combined with LCBDE and opening of the pancreatic capsule for drainage in 1. Results In all the patients, the laparoscopic operations were completed successfully without conversion to open surgery. The operation time was 100-150 min with a mean of (115.3?15.2) min. The stones in the bile duct were removed completely by LCBDE in 10 patients. No subcutaneous emphysema, hemorrhage, abdominal abscess or stenosis of the bile duct occurred in this series. The 18 patients were followed up for 4-40 months (mean, 28.5 months), during which 2 patients developed pancreatic pseudocyst. One of the patients was cured by internal drainage. In the other patient, the pseudocyst was absorbed spontaneously. No recurrence of pancreatitis or common bile duct stones was found. Conclusions Laparoscopic surgery is minimally invasive and effective for the treatment of ABP at early stage.

Objectives To observe the effect of inhibition of transforming growth factor (TGF)?1 on the growth and aggression of colon cancer cells by RNA interference. Methods HCT116 colon cancer cells were transfected with small interfering dsRNA (siRNA), the effect of the inhibition of TGF?1 was tested by semi-quantitative RT-PCR, and changes in cell cycle distribution were analyzed by flow cylometry, the ability of aggression was detected by soft agar colony assay. Results The inhibition of the expression of TGF?1 was significantly detected after the transfection of siRNA against TGF?1, which induced the increase of S phase by 59.0%-82. 5% and decrease in G2 phase, colony assay further demonstrated that siRNA against TGF?1 led to a significant reduction in colony formation as compared with the control group. Conclusions The present data suggested that the expression of TGF?1 was conveniently and rapidly blocked by siRNA transfection, and this may lead to the cell cycle arrest and inhibition of the growth and tumorigenesis of colon cells.

Pain has been defined as an unpleasant sensory and emotional experience that is associated with actual or potential tissue damage,or is described in terms of such damage.Pain individual difference increases the complexity of clinical diagnosis and treatment of pain.China started relatively late on pain research and standardized pain treatment.It is necessary for further research on pain related to the clinical problem,the development of pain translational medicine,and improvement of clinical quality.The paper carries on the review.
