Objective To research the optimum hydrolysis conditions of oyster protein so as to raise the protein recovery and degree of hydrolysis.Methods Considering protein recovery,degree of hydrolysis,bitterness and clarity,the best enzyme was selected;Orthogonal test was designed to determine the best enzyme hydrolysis conditions;Based on hydrolysis and protein recovery,the effect of heat treatment,ultrasound and microwave processing and handling on enzymatic hydrolysis of oyster were investigated.Results and Conclusion Bromelain protease was suitable for the proteolysis of oyster,and the optimal conditions were:pH 6,temperature 55℃,substrate concentration 1∶3,E/S=800U/g,4 hours.In the optimal condition,the recovery of protein and degree of hydrolysis were 67.55%and 29.86% respectively in the hydrolysate.Heating,ultrasound technology and microwave treatments before hydro-lysis were harmful to enzymatic hydrolysis of oyster.

Climacteric syndrome is a common clinical disease with high incidence.The understanding of the disease is progressing in recent years.This article collects thirty-seven documents in this field in recent eight years.The pathogenesis of climacteric syndrome is divided into two aspects as the deficiency of the kidney and the imbalance of the liver, the spleen and the heart.It also sums up the therapy of climacteric syndrome from this two aspects.At last, the authors propose that we should pay attention to the importance of the liver, the spleen and the heart in both the pathogenesis and the therapy.

Comparing with the world level, the bibliometric indicators of Chinese medical journals in oncology field are rather lower, but our medical journals have big development space. In the world journals with high impact index, the papers published by Chinese authors are fewer; in the papers number, the superiority of Chinese authors is in tumor clinical therapy field. Most papers are written by researchers from large institutions with plenty of medical resources.

Since the emergence in 1980s,community-associated methicillin-resistant Staphylococcus Aurues (CA-MRSA) has caught great attention of the researchers and clinical practitioners all over the world. In recent scientific papers,people found that CA-MRSA's capability to adapt itself to the hostile environment and to colonize is a kind of important virulence factor. A newly unveiled gene,designated arginine catabolic mobile element (ACME),in USA300 stains contributes much to this sort of ability. The arginine deiminase encoded by ACME plays an important role in colonization.

Objective To observe the effect of combination of Tju103 and CTLA4-Ig on engraftment, graft versus host disease (GVHD), graft versus leukemia (GVL) and anti-infection post major histocompatibility complex (MHC) haploidentical bone marrow transplantation in mice in order to seek an effective access to transplantation with less GVHD and more potential GVL and anti-infection.Methods In the presence of the recipient's antigen (normal CB6F1, H-2 bd) as a stimulus for induction of specific immune tolerance, T cells from the MHC haploidentical donors (C57BL/6, H-2 b) were first in vitro cultured with Tju103 and CTLA4-Ig, then were transfused with the donors' bone marrow cells into the preconditioned recipients. At last, the effect of combination of Tju103 and CTLA4-Ig on hematopoietic rebuilding, GVHD, GVL and anti-infection was observed in compared with CsA, Tju103 and CTLA4-Ig as controls.Results The only irradiated group (group A): All the mice (10 mice) died of failure of hematopoiesis within 11 days post irradiation, of which most (8 mice) died within 4～7 days post transplantation. The CTX-treated leukemia group (group B): All the mice (10 mice) died of leukemia within 16～23 days post leukemia cells infusion (11～18 days post BMT). CTX treatment prolonged the survival time. The only transplanted group (group C): The mice began to die from day 16 post transplantation, and all (10 mice) died of GVHD within 3 weeks. The CsA prophylaxis group (group D): 4 mice died within 8～22 days after transplantation, of which one died of leukemia, two died of infection and one died of GVHD, and the remaining 6 survived over 30 days post transplantation. The Tju103 treated group (group E): 4 mice died within 9～26 days post transplantation, of which one died of leukemia, one died of infection and two died of GVHD, and the remaining 6 mice survived over 30 days post transplantation. The CTLA4-Ig treated group (group F): 3 mice died within 14～23 days after transplantation, of which one died of infection and two died of GVHD, and the remaining 7 survived over 30 days post transplantation. The Tju103/CTLA4-Ig treated group (group G): one died of GVHD on day 19 after transplantation, and the remaining 9 mice survived over 30 days post transplantation. Conclusions CsA, Tju103 or CTLA4-Ig alone could prolong survival time and reduce incidence and degree of GVHD severity. But CTLA4-Ig could spare much ability of GVL and anti-infection while Tju103, just like CsA, couldn't. Combination of both was the most favorable way for transplantation with the most remarkable efficiency on prolongation of survival time and reduction of GVHD.

Method Analyzed the ultrasonic character by reviewing the fetal congenital cordis malformation from our hospital in recent 2 years. Result 3 cases was inaccuracy in the 28 cases of congenital cordis malformation diagnosed by antepartum. Diagnostic accuracy rate was 89.3%. Conclusion The inaccuracy was reduced greatly by gradual ultrasonic diagnosis by way of four cavity heart and three vas cross section,

Objective To observe the analgesia effects of ropivacaine with sufentanil or dezocine on continuous femoral nerve block (FNB)after total knee arthroplasty (TKA).Methods Sixty un-dergoing selective unilateral TKA patients,received postoperative analgesia with continuous FNB for 48 hours,were randomly divided into three groups according to the drug formulations:0.225% ropiv-acaine (group R),0.1 5% ropivacaine mixed dezocine 10 mg (group D),and 0.1 5% ropivacaine mixed sufentanil 1 μg/kg (group S);the visual analogue scale (VAS)in resting state (RVAS), active functional exercise state (AVAS),passive functional exercise state (PVAS)were recorded at 1,3,7 d after surgery.The other analgesics dosage and the incidence of nausea and vomiting and other complications were recorded.Results Compared with preoperative state,the RVAS scores in three groups were significantly lower at 1,3,7 d after surgery,the PVAS scores were significantly lower at 7 d after surgery (P <0.05).Compared with group R,the RVAS scores were significantly higher ei-ther in groups S or D at the 3 d postoperatively (P <0.05).There were no significantly difference in adverse reaction among three groups.Conclusion Ropivacaine combined with sufentanil or dezocine through continuous FNB can provide a effectual postoperative analgesia in TKA patients without an increase in adverse events.But compared to 0.225% ropivacaine,0.1 5% ropivacaine with sufentanil or dezocine may not keep a longer analgesia duration,this is more obvious observed in dezocine group.

Objective To study the association between three single nucleotide polymorphisms (SNP; rs2241766,rs1501299 and rs12495941) variants of the adiponectin gene (ADIPOQ) and polycystic ovary syndrome (PCOS) in PCOS family trios.Methods A total of 224 unrelated PCOS probands,their biological parents were recruited.Anthropometric variables such as waist circumference (WC),hip circumference (HC),height and weight were measured in all subjects during the first visit to the outpatient department.Body mass index (BMI) and waist-hip ratio (WHR) were calculated.Serum fasting glucose (FBG),fasting insulin (FINS),total cholesterol (TC),triglycerides (TG),low-density lipoprotein and highdensity lipoprotein cholesterol (HDL) levels were measured.PCOS patients were divided into two groups based on BMh group A (BMI＜25 kg/m2) and group B (BMI≥25 kg/m2).Parents of PCOS patients were accordingly categorized into group C,D (fathers) and group E,F (mothers).The transmission disequilibrium test (TDT) was used to analyze the association between three SNP of ADIPOQ and PCOS.Results (1) A significant positive association was detected between SNP rs1501299 and PCOS (x2=7.093,P=0.008).However we failed to find significant overtransmission of the other two SNP rs2241766 and rs12495941 from parents to PCOS offsprings (x2=1.620,P=0.203; x2=0.713,P=0.398).(2) Linkage disequilibrium (LD) was analyzed in the subjects,rs1501299 and rs2241766 were in weak LD (r2=0.063,D'=0.621).(3) The levels of WC,HC,WHR,testosterone,TG,HDL and FINS were significantly differences between obese and lean PCOS patients (P＜0.05).While in fathers we only found WC,HC,TC levels being statistically different (P＜ 0.05).Mothers of obese PCOS patients had increased levels of FINS compared with mothers of lean PCOS patients (P＜0.05).The genotype frequencies of the three SNP were not different in obese and lean PCOS patients and their parents (P＞0.05).Conclusions TDT confirms that SNP rs1501299 in the ADIPOQ is significantly associated with the risk of PCOS in the Chinese Han population.The three SNP of the ADIPOQ were not associated with the obesity of PCOS.

The leaves of Rumex dictyocarpus Boiss et Buhse are used for treatment in acute abdomen. From this plant four constituents have been isoiated and identified as emodin、chrysophanol、quercetin、quercitrin by chemical and spectroscopic methods. These constituents were known to possess antibacterial, anti-inflammatory or hemoslatic actions, it seems that the clinie effects are related to the presense of these constituents.
