Objective To investigate the expression of serum microRNA-210 (miR-210) in patients with acute cerebral infarction(ACI),and to evaluate its clinical significance. Methods A retrospective study was conducted. Eighty patients with ACI admitted to Tianjin Hospital from January 2011 to March 2014 within 48 hours of onset were enrolled,and 30 healthy volunteers served as controls. The peripheral blood was collected,and the expression of serum miR-210 was determined by reverse transcription-polymerase chain reaction(RT-PCR). The receiver operating characteristic curve(ROC)was drawn to analyze the role of miR-210 in the diagnosis of ACI. According to the pathological and physiological characteristics of patients receiving treatment,the relationship between miR-210 and clinical physiology index was analyzed. Results The expression of miR-210 in serum of patients with ACI was significantly lower than that of the healthy control group(2-ΔΔCt:1.349±0.043 vs. 1.923±0.107,t=6.567, P<0.000). ROC analysis results showed that the sensitivity of miR-210 in the diagnosis of ACI was 90.4%,the specificity was 76.2%,and the area under the ROC(AUC)was 0.804〔95%confidence interval(95%CI)=0.700-0.908〕. No difference in expression of miR-210(2-ΔΔCt)in serum was found in patients of different gender,age, and infarction area(male and female:1.33±0.13 and 1.31±0.06,t=3.562,P=0.473;≤60 years and>60 years:1.32±0.12 and 1.31±0.09,t=2.351,P=0.264;large infarction,small infarction,lacunar infarction:respectively 1.31±0.02, 1.33±0.11, 1.31±0.06, F=1.236, P=0.087), or with the severity of cerebral infarction,and there was a tendency in lowering of expression of miR-210(2-ΔΔCt,light,medium,severe:1.53±0.11, 1.33±0.11,1.08±0.04,F=5.394,P=0.014).Conclusion The serum level of miR-210 in ACI was significantly lower than that in normal healthy persons,and it may be an important new serological marker in screening and diagnosis of ACI.

Objective To assess Chinese parental requirement for relieving their preoperative anxiety,and their attitudes regarding the measures reducing their anxiety and to investigate the possible factors associated with increased anxiety.Methods One hundred and four pairs of pediatric patients (aged 2-12 yr,of ASA physical status Ⅰ or Ⅱ) undergoing elective surgery under general anesthesia and their parents were enrolled in this study.The general data of the pediatric patients and their parents and parental requirement for relieving their preoperative anxiety,and their attitudes regarding the measures reducing their anxiety were obtained using a questionnaire.Parental and children's anxiety? levels were assessed using the State-Trait Anxiety Inventory (STAI) and modified Yale Preoperative Anxiety Scale (m-YPAS),respectively.Results Parental anxiety levels were positively correlated with the children's anxiety levels (r =0.254).Parental desires to relieve their own anxiety under the personal direction of medical staff were significantly higher than the desires for the other measures; parental desires to relieve their own anxiety through parent-present induction of anesthesia (PPIA) were significantly lower than the desires for the other measures.The factors influencing parental attitudes included gender,educational level,preoperative anxiety level,and preoperative children' s anxiety level.Conclusion To relieve Chinese parental anxiety before surgery,the anesthesiologists should be aware that the majority of parents have a high desire to receive verbal instructions from medical staff before surgery was performed on their children and should provide enough information related to anesthesia and surgery; when PPIA is applied,parental desire for PPIA should be taken into full account; the anesthesiologists offer support and comfort for the parents properly.

Objective To evaluate the clinical diagnosis and the clinical application value of serum CEA,CA19-9 and CA242 in patients with colorectal cancer. Methods The serum levels of CEA, CA19-9 and CA242 were concomitantly determined by ELISA in 150 preoperative patients with colorectal cancer, and 200 healthy people as a control group. Results The levels of CEA, CA19-9 and CA242 in patients were higher significantly than that in controls (P

Objectives To study the expression features of C-type natriuretic peptide (CNP)/natriuretic peptide receptor-B (NPR-B) axis and two parallel elimination pathways, natriuretic peptide receptor-C (NPR-C) and neutral endopeptidase (NEP) in unilateral ureteral obstruction (UUO) rats. Methods CNP, NPR-B, NPR-C, NEP, Col-IV and type IV collagen (Col-IV) mRNA and proteins were determined by in situ hybridization, real-time PCR, immunohistochemistry and western blot in UUO rats at 24h, 72h, 1w, 2w, 3w, 1m, 2m and 3m. Results CNP expression tended to be higher immediately after ligation and de-clined along with the progression of disease, occurring predominantly in tubular epithelial cells. A high-level CNP may attribute to the elevated expression of NPR-B in the early phase of UUO. Conclusions NEP and NPR participate in the regulation of CNP expression in tubulointerstitial fibrosis. The gradual increased expression of NPR-C and NEP may cause the subsequent de-cline of CNP.

Background Pterygium is a relatively common eye disease,but its aetiology and pathogenesis remain uncertain.At present,the study on pterygia focuses on understanding its underlying mechanism.Objective This study was to detect the expression of 8-hydroxy-2'-deoxyguaine (8-OHdG),a marker of oxidative damage of DNA,and bcl-2,a gene related with apoptosis,on the pterygium tissue.Methods Thirty pterygium tissue specimens were obtained during the surgery with the primary pterygium 24 cases and recurrent pterygium 6 cases.In addition,20 normal conjunctival specimens from retinal detachment surgery and strabismus surgery were collected.The expressions of 8-OHdG and bcl-2 in pterygium tissue were detected using immunochemistry and compared with the normal conjunctival tissue.The difference in the expressions of 8-OHdG and bcl-2 among different specimens was compared by x2test,and the relationship between 8-OHdG expression and bcl-2 expression was evaluated by Kappa test.Results The positive expressing rate of 8-OHdG in the pterygium tissue was 62.5％ and 83.3％ in the primary and recrudescence pterygium tissue,respectively,but the expression of 8-OHdG was absent in the normal conjunctiva tissue.No significant difference was found in the positive expressing rate of 8-OHdG between primary and recrudescence pterygium tissue(x2 =0.938,P＞0.05).The bcl-2 expressing rate was 90.0％ and 87.5％ in the primary and recrudescence pterygium tissue,respectively.However,that in the normal conjunctival tissue was absent.No significant difference was seen in the bcl-2 expression rate between primary and recrudescence pterygium tissue (x2=0.833,P ＞ 0.05).Of the 27 pterygium tissue with bcl-2 positive expression,8-OHdG showed the positive expression in 20 specimens,and 3 specimens with the bcl-2 negative response were absent reactive to 8-OHdG,showing insignificant difference between them (P＞0.05).The relationship between 8-OHdG expression and bcl-2 expression was concord in a certein extent (Kappa =0.464).Conclusions The upregulation of 8-OHdG in the pterygium tissue indicates that oxidative damage of DNA plays a role in the development of pterygium.Oxidative damage of DNA caused by ultraviolet may be an upriver factor,which induces raising up of expression of bcl-2 and inhibits the apoptosis of normal cells and further proliferation of the conjunctiva tissue,resulting in the genesis and development of pterysium.

BACKGROUND:In the process of designing knee joint prosthesis and operating total knee arthroplasty for the Chinese people, we should not only take into account the proximal tibial anatomical characteristics and the difference of geometry, but also should pay attention to the differences between different races. OBJECTIVE:To compare the anatomical morphological differences between Mongolian and Han nationality through measuring the CT tomography scanning and three-dimensional reconstruction measurement of tibia proximal part of Han and Mongolian nationality, so as to provide the data references for prosthesis selection used for total knee arthroplasty. METHODS:Total y 60 patients who received the treatment at the Department of Joint Surgery were col ected, and divided into Han nationality and Mongolian nationality groups (n=30/group, 15 males and 15 females in each group). The age was (36.00+7.22) years old. 16-row helical CT scan (American GE Lightspeed 16) was used for spiral scanning, slice thickness 0.625 mm. Scanning images were exported in DICOM format and saved. Digital three-dimensional reconstruction measurement was conducted using Mimics 15.0 three-dimensional reconstruction software. The tibial plateau width, anteroposterior diameter of the medial tibial plateau and lateral anteroposterior diameter were measured respectively to observe whether there were any differences among sex, sides and nationality. RESULTS AND CONCLUSION:There were no significant differences in the above indicators between left and right sides (P>0.05). There were significant differences in tibial plateau width, anteroposterior diameter of the medial tibial plateau and lateral anteroposterior diameter between males and females, and Han and Mongolian nationality groups (P<0.05). Specific performed in:(1) There was significant difference in the morphological measurement parameters of proximal tibia between sex for Han and Mongolian nationality, and the mean value of male was larger compared with that of female. (2) There was certain significant difference in the part of the parameter indicators between Han and Mongolian nationality groups. These results suggest that the prosthesis should be chose and placed correctly according to the differences of morphological characteristics, gender, nationality, region of the Chinese people. (3) Digital three-dimensional reconstruction technology and individualized design can choose suitable prosthesis for different people, so as to ensure a good repair effect in patients after total knee replacement.
