Objective To study the cause of placental abruption and relationship of outcomes of different clinical types of placental abruption.Methods 35 patients with placental abruption hospitalized were retrospectively analyzed. Results The incidence of placental abruption was 0. 3％. The rate of type Ⅰ was 60. 0％ (21cases) ,type Ⅱ 31.4％ ( 11 cases) and type Ⅲ 8. 6％ ( 3 cases). The gestational hypertension was the main cause of placental abruption. The rate of antepartum ultrasonic diagnostic was 40. 0％. The cesarean section rate was 71.4％. The incidence of postpartum hemorrhage, uteroplacental apoplexy and shock, DIC and partial hysterectomy on uterus were 22. 8％ (8 cases) ,8.6％ (3 cases) and 8.6％ (3 cases) ,respectively. The mortality rate of perinatal newborn was 14. 3％ (5 cases). Conclusion The gestational hypertension was the main cause of placental abruption. There was close relationship between the degree of placental abruption and different pregnant outcomes of women.

Objective To research the clinical outcome of atypical glandular cell (AGC)according to various subtypes of HPV infection and histological pathology results.Methods The data of the liquid-bases cytology (LBP),HPV infection and histology in 102 cases of AGC at the gynecology outpatient department of our hospital from January 1 ,2009 to February 28,2014 were collected and performed the analysis on their clinical outcomes.Results Among 67 218 cases of LBP detection,102 cases were AGC with the total incidence rate of 0.15%.In the cases of AGC-NOS,67 cases were normal or benign lesions,11 cases were precancerous lesion and malignant lesions;in the cases of AGC treading to tumor,the benign,precancerous and malignant lesions were in 7,14 and 3 ca-ses respectively.At the same time in the cases of AGC-NOS,HPV infection was in 64 cases,in which 57 cases were high risk infec-tion(type 16,52,45)and 7 cases were low risk infection(type 6,11 ).The single infection,double infection and multiple infection were in 54,6 cases respectively;in the cases of AGC trends to neoplasm,HPV infection was in 19 cases,in which 18 cases were high risk infection(type 52,16,18)and 1 case was low risk infection(type 6),single infection and double infection were in 15 cases and 4 cases respectively.Conclusion AGC may play an important role for the forecast of cervical malignant lesions.The results of differ-ent HPV subtypes infection in AGC related tumors also play a certain role in the prediction of cervical neoplasia.Their combined a-nalysis is the important signal for judging the occurrence of gynecological cervical precancerous lesion and malignant tumor,i.e., AGC combining with the corresponding HPV subtype infection not only can make a judgement for the cervical lesions,but also pro-vides the basis for predicting the high risk existence of gynecological malignant tumor and provides constructive suggestions for Chi-na regional cervical carcinoma vaccine manufacturing and promotion.

Objective To investigate the influences of survivin down-regulation on cell G2/M phase arrest,apeptosis and sensitivity to carbon ion irradiation. Methods Small interfering RNA (siRNA) targeting survivin mRNA was designed, in vitro chemo-synthesized and transfected into SMMC-7721 cells. Survivin mRNA expression in SMMC-7721 cells was measured by real-time PCR, and the apeptotic rates by Annexin-FTTC at 24 and 48 h after transfection. Cell G2/M phase arrest after transfection was assessed with flow eytometry as well. Cellular sensitivity to high-LET carbon ions was determined by means of colony-forming assay. Results The expressions of survivin at mRNA level were down-regulated to be 59% and 39% in relation to the non-treated cells at 24 and 48 h after siRNA transfeetion, respectively. G2/M phase arrest in SMMC-7721 cells at 24 h after transfection was observed while much more obvious at 48 h. The apeptotic rate of SMMC-7721 cells was 21.41 % at48 h after survivin siRNA transfection, which was significantly higher than that of the cells transfected with negative siRNA. Moreover, a decreased clonogenic survival in siRNA treated group was shown. Conclusion Down-regulation of survivin gene expression in SMMC-7721 cells by siRNA could effectively induce cell apeptosis and G2/M phase arrest, and enhance the cellular radiosensitivity to high-LET heavy ions.

Objective To study the relationship of CSF and serum FGF-2 level with clinical parameters in MND patients.Methods Ninety-one MND patients served as a MND group and 40 noninflammtory nervous system disease patients served as a control group.Their CSF and serum FGF-2 level were measured by ELISA.The neurological deficit in ALS patients was assessed according to the modified ALSFRS-r,the progression of MND was assessed according to the DPR.The ALS patients were followed up,during which their survival time was recorded.Results The serum FGF-2 level was significantly higher in MND group than in control group (P＜0.01).The CSF,FGF-2 level were significantly higher in ALS patients of MND group than in those of control group (319.2±105.9 ng/L vs 241.7±34.3 ng/L,P＜0.01).The CSF and serum FGF-2 level were positively correlated with the duration of MND and negatively correlated with the DRP in ALS patients (P＜0.01).Survival analysis of MND patients indicated that the survival time of PMA patients was longer than that of PLS,ALS and PBP patients (P=0.000).The cumulative survival rate of ALS patients with a high serum FGF-2 level was significantly higher than that of those with a low serum FGF-2 level (P=0.002).Conclusion The CSF and serum FGF-2 level are higher in some MND patients and can be used as one of the biomarkers for evaluating the progression and predicting surrival.

Objective To study the clinical significance of serum hs-CRP level in smokers with carotid atherosclerosis (CA) and analyze its difference in subtypes of CA.Methods Two hundred and ninety-eight smokers with CA served as a smoker group and 120 non-smokers with CA served as a non-smoker group,50 healthy smokers without CA served as control group 1 and 50 healthy non-smokers served as control group 2.Their serum hs-CRP level was measured by colloid-enhanced immunoturbidimetry.Smokers were divided into stable plaque group and unstable plaque group.Effect of smoking on serum hs-CRP level in CA patients was analyzed.Results The serum hs-CRP level was significantly higher in smoker group and control group 1 than in non-smoker group and control group 2 (7.26±4.24 mg/L vs 3.56±2.28 mg/L,4.34±2.74 mg/L vs 3.17± 1.68 mg/L,P＜0.05).The smoking index was positively related with the serum hs-CRP level (r=0.395,P＜0.01).The number of daily smoked cigarettes was significantly greater in unstable plaque group than in stable plaque group (P＜0.05).The recurrence rate of ischemic stroke was significantly higher in smokers with a high serum hs-CRP level than in those with a low serum hs-CRP level (11.36％ vs 2.00％,P＜0.01).Conclusion Smoking can increase the serum hs-CRP level in CA patients,which is closely related with the stability of plaques and the recurrence of ischemic stroke.

Objective To analyze the correlation of plasma homocysteine (Hcy) level with hemodynamic parameters and high density lipoprotein cholesterol (HDL-C) level in patients with lacunar infarction and its significance in lacunar infarction.Methods Transcranial Doppler examination was performed in 120 patients with lacunar infarction admitted to our hospital from February 2012 to March 2013 and 100 healthy controls; systolic flow velocity (SFV),distalotic flow velocity (DFV),mean flow velocity (MFV) and pulsatility index (PI) were assessed at the middle cerebral artery (MCA) and basilar artery (BA).Serum creatinine,total cholesterol,triglycerides,HDL-C,and low-densitylipoprotein cholesterol (LDL-C) levels were detected using enzymatic colorimetric method.Plasma Hcy level was measured by circulating enzymatic method.Results Blood flow velocity indexes,such as SFV,DFV,MFV and PI in the MCA of lacunar cerebral infarction patients,were significantly higher than those in their BA and the MCA blood of control group,with statistically significant differences (P＜0.05); blood flow velocity indexes,such as MFV and PI in the BA of lacunar cerebral infarction patients,were higher than those in the BA of the control group,with significant differences (P＜0.05).Lacunar cerebral infarction patients had significantly higher levels of Hcy,total cholesterol,LDL-C,tdglycerides,and HDL-C as compared with control group,with statistical differences (P＜0.05).Linear correlation analysis showed that PI of MCA and BA and Hcy level were positively correlated in lacunar infarction patients (r=0.530,P=0.020; r=0.450,P=0.010); and HDL-C and Hcy levels had negative correlation (r=-0.308,P=0.010).Conclusion A significant association between plasma Hcy and PI of cerebral arteries and serum HDL-C level indicates that Hcy plays a role in the increase of distal arterial resistance in lacunar infarction.

[Objective] To explore the effects of different methods on antibody detection through investigating the causes of cross-matching incompatible in a patient with gastric malignant tumor, and to establish flow cytometry protocol for confirming hemolytic transfusion reaction (HTR). [Methods] Antibodies in the patient's serum were identified by red blood cells (RBCs) blood grouping, antibody screening and identification, acid elution test and PEG enhancement test. To confirm HTR, patient RBCs, proximal and distal ends RBCs, separated by capillary centrifugation, were tested by direct antiglobulin test (DAT) and Jk^a antigen single label and double label flow cytometry. [Results] Routine serological technology revealed the presence of anti-C, e (titer:2) and anti-Jka (titer >1) in the patient’s serum. After separation using capillary centrifugation technology, both the proximal and distal DAT and Jk^a antigen tests were negative. Both DAT and Jk^a antigen positive red blood cells (0.21%, 6/6 327) were found in the patient's blood samples by flow cytometry. After separation of blood samples by capillary centrifugation, there were significantly more DAT and Jk^a antigen double-positive RBCs in the distal end (0.43%, 33/7 707) than in the proximal end (0.09%, 15/7 225). Two blood samples were screened from over 100 donor blood samples that are compatible with the patient's cross-matching, and the transfusion effect was favorable. [Conclusion] Serological methods combined with flow cytometry could improve the sensitivity of antibody detection, provide a more accurate basis for the diagnosis of HTRs, and guarantee the safety of blood transfusion.
