1.Neurodegenerative diseases and endoplasmic reticulum stress
Chinese Journal of Behavioral Medicine and Brain Science 2017;26(2):183-187
Neurodegenerative diseases,which are common nervous system diseases,seriously affect people''s life quality and even lives. So the pathogenesis of neurodegenerative diseases is attracting more and more attention in recent years. People gradually realize that endoplasmic reticulum stress is associated with the pathogenesis of many diseases through studying the function of the endoplasmic reticulum. Neurodegen-erative diseases, endoplasmic reticulum stress,unfolded protein responsewere used as the key words of retrieval performance in the databases such as Pubmed,CNKI and so on. And the papers which closely re-lated with the theme were chosen to investigate the association between alzheimer''s disease,parkinson''s dis-ease,Huntington'' s disease ,amyotrophic lateral sclerosis and ERS. It turned out that the expression of mo-lecular chaperone GRP78/Bip was increased in all neurodegenerative diseases, and the phosphorylation of eIF2α increased in most neurodegenerative diseases. However, the expression of some ERS-related factors was completely different in different neurodegenerative diseases. Thus,the study of ERS may be an important breakthrough for the pathogenesis and treatment of neurodegenerative diseases.

Objective To study the value of intraoperative cholangiography(IOCG) in cholecystectomy for gallbladder stone. Methods The IOCG data of 694 cases in the Affiliated Hospital, Yanan University Medical School were retrospectively analysed. Results Among 694 cases with IOCG, 65 had positve findings. Bile duct stone occurred in 44 patients, residnal stone in cyst duct in 7, bile duct injury in 2, and Mirizzi syndrom in 3. Among the 44 cases with bile duct stone, the age of 4.3% cases was 22~50 years old, 10.3% older than 50 years. The incidence of bile duct stone occurring after 50 years old increased with age. The accurate rate of IOCG was 98% in this series. Conclusions IOCG can not only find residual stone, but also find bile duct abnormality and bile duct injury in time, if correct imagic technique is applied.
4.Functions of human periodontal myofibroblast in vitro.
West China Journal of Stomatology 2015;33(2):130-134
OBJECTIVETo investigate the functions of human periodontal myofibroblast (MFB) in vitro.
METHODSHuman periodontal fibroblast (hPDLFs) was cultured and induced to MFB by transforming growth factor-β1 (TGF-β1). MFB was denoted as the experimental group, whereas the hPDLFs was the control group. The groups were continuously cultured and harvested at 0, 12, 24, 48, and 72 h. The MFB marker α-smooth muscle actin (α-SMA) was examined by immunocytochemistry. The expression of fibronectin (FN) between MFB was examined by immunocytochemistry to detect the MFB contact relationship. The mRNA expression levels of α-SMA, collagen (Col) I, and Col III were measured by reverse transcription-polymerase chain reaction (RT-PCT) to analyze extracellular matrix secretion. The protein expression levels of α-SMA and Col I were also assessed by Western blot.
RESULTSThe experimental group had significantly higher α-SMA expression than the control group at 0 h (P < 0.001). A positive expression of FN was found between MFB. The experimental group had significantly higher expression levels of Col I and Col III than the control group at 24 h (P < 0.001).
CONCLUSIONHuman periodontal MFB presents a continuous, high expression of α-SMA. MFB could interact through FN. MFB is significantly capable of extracellular matrix secretion.

Objective To analyze the correlation between 5-hydroxytryptamine transporter gene linked polymorphic region(5-HTTLPR) and twin children's behavioral problems and its interaction with environmental factors.Methods A total of 147 pairs of school-age twins aged 6-12 years were enrolled.The behavioral problems were assessed with the Child Behavior Checklist (CBCL).The genotype of 5-HTTLPR was detected by the method of PCR.The correlation of 5-HTTLPR and children's behavioral problems was performed using generalized estimating equation.Results (1) The overall incidence rate of behavioral problems in school-age twins was 24.15% (27.94% in the boys;20.89% in the girls),in which the rate of thinking problems (15.31%) was the highest,and the rates of other problems were lower (3.40%-8.16%).(2) The results of correlation analysis showed that 5-HTTLPR was only related to the social problems (P< 0.05).The S allele of 5-HTTLPR maybe associated with the social problems.(3) The results of interaction of 5-HTTLPR with twin factors of themselves and family environmental factors showed that 5-HTTLPR was the main effect of the anxious/depressed problems,and S allele carriers were easier to occur anxious/depressed problems.Gender was the main effect of the social problems,and boys were easier to occur social problems.There was no significant interaction between 5-HTTLPR and twin factors of themselves and family environmental factors.Conclusion 5-HTTLPR genetype may have some relevance to the social and anxious/depressed problems,and S allele may be a susceptibility gene of social and anxious/depressed problems.

Objective To analyze the β-lactamases-producing Escherichia coli which were isolated from hospital specimens from Jun 2012 to Dec 2014,and provide a more accurate evidence to guide drug-selecting for antibacterial use.Methods An-alyzed 1 587 E.coli from patient sample selected between Jun 2012~Dec 2014 using the microbial analysis system manufac-tured by ZHUHAI DL BIOTECH CO.LTD,A phenotypic test was also conducted to test ESBLs.Results 1 587 stains of E-.coli were isolated,which counted for 23.9% of the specimens;901 stains (56.8%)out of total 1 587 stains appeared to be ESBLs-producing E.coli,and others were non-ESBLs-producing E.coli.The 1 587 Escherichia coli mainly came from De-partment of Urology (408,weight 25.7%),Department of Endocrinology (271,weight 17.1%),Department of Respiration (249,weight 15.7%).Rine specimen contributed 609 stains (47.3%),411 E.coli stains (31.9%)were discovered in spu-tum samples,and 83 stains (6.5%)showed in blood samples.The resistance to imipenem were discovered in the analysis. The rates of resistance to penicillins,cephalosporins were over 90.0%,the rates of resistance to Levofloxacin,ciprofloxacin were above 70.0%,and resistance rates to amoxicillin-clavulanic acid,Ticarcillin-clavulanic acid,piperacillin/tazobactam, amikacin were lower than 7.7%.Conclusion The drug-resistance of the E.coli were increasing over the past three years. There was a significant portion of MDR and PDR present in the trend.Thus,the reinforcement of the drug-resistance survey and testing have a far-reaching meaning to promote rational drug selecting.

Objective To evaluate the effect of procedure for prolapse and hemorrhoid(PPH)for the treatment of prolapsed internal hemorrhoids. Methods 23 patients with the third or fourth degree circular prolapsed internal hemorrhoids were managed by means of PPH. Results The mean operative time was 22 minutes,and hospital stay was 3.5 days after operation.Pain in 48 hours after operation was evaluated and 18 cases had no pain(78 3%),5 cases less pain(21 7%).The anastomoses healed in (4~5) weeks and there was no recurrence in (1~6) months after the patients were discharged from hospital. Conslusions Compared with the traditional operation,PPH has the advantages of simpleness,less pain,less complications and quiker recovery,but the cost is higher.

Objective To analyze the adverse drug reactions(ADRs)of edaravone in treatment of patients with acute cerebral infarction(ACI)by reviewing Chinese medical literature and to evaluate safety of edaravone treatment in ACI.Methods Publications from Pubmed and Chinese Biomedical Literature Datababe(CBMdisc)were reviewed and the ADR of edaravone was analyzed among the published 8645 cases.Literatures about randomed-control clinical trails(RCTs)on security of edaravone for treating ACI Was analyzed by meta-analysis.Results Abnormal hepatic function,especially mild elevation of aminotransferase,renal dysfunction and skin rash induced by edaravone were tIle most common ADRs.Among 8645 patients,ADRs were reported in 283(3.27 % ).The meta-analysis in RCTs showed that between the group treated with a combination of edaravone and routine and the group treated with routine treatment only,there was no significant difference in the occurrence rate of ADRs(OR=1.18,95 % CI0.70-2.00,P=0.536),elevation of aminotransferase(OR=1.23,95 % CI 0.57-2.68,P=0.595)or renal dysfunction including albuminutia,increased level of serum ereatinine and nitrogen(OR=1.65.95 % CI0.57- 4.79.P=0.353).Conclusion Edaravone has a low ADRs OCCurrence rate and iS safely used in cerebral infarction treatment.
