Objective To evaluate the value of plasma soluble urokinase?type plasminogen activator receptor (suPAR)and D?dimer for assessing disease severity and prognosis in patients with traumatic brain injury(TBI). Methods A serial of 112 patients with traumatic brain injury admired to our hospital were divided into mild TBI (GCS score 13~15),moderate TBI(GCS score 9~12)and severe TBI(GCS score 3~8). The levels of plasma suPAR and D?dimer were monitored within 24 h after patient admission. Results The levels of suPAR and D?di?mer in TBI group were obviously higher than those in the control group(15.86±7.33 vs 2.79 ± 0.69,P<0.01;3.50 ± 2.78 vs 24 ± 0.15,P<0.01). The levels of suPAR and D?dimer in the severe TBI group were also obviously high?er than those in the moderate TBI group(P<0.05). Plasma suPAR levels and GCS score had significant negative correlation(r =- 0.854,P < 0.01). D?dimer levels and GCS score showed a negative correlation(r =- 0.738, P < 0.01). Plasma suPAR and D ? dimer was positively correlated(r = 0.753,P < 0.01). The area under the curve of D?dimer(AUC)was larger,0.854,95%CI 0.763~0.945;the AUC of suPAR was 0.801,95%CI 0.698~0.903. Conclusion Higher levels of suPAR and D?dimer in TBI patients is not only relevant to the injury sever?ity ,but also closely to the prognosis.

Objective To investigate the variation of corticotropin-releasing hormone(CRH)in plasma,the mRNA and protein expression of c-Fos and gap junction gene connexin-43(Cx43)in the myometrium of term pregnancy women,and to study the correlations among CRH,Cx43 and c-Fos at onset of labor.Methods 30 cases in labor(L group),30 cases not in labor(NL group)but in term pregnancy, and 30 cases of non-pregnant(NP group)women undergoing hysterectomy due to cervical intraepithelial neoplasia were recruited into this clinical study.Radioimmunoassay was employed to measure the concentration of CRH in plasma;in situ hybridization assay and streptravidin-biotin peroxidase(SP) immunohistoehemical techniques were respectively used to detect the expression levels of c-Fos mRNA,Cx43 mRNA and the corresponding proteins.Results(1)The concentration of CRH in L group(81.8?11.9) pmol/L was significantly higher than that in NL group(34.5?18.6)pmol/L(P

Objective:To understand the responsiveness of community health service institutions in Henan Province. Methods:This research collected information through questionnaire investigations. The object of the investigations is key informants familiar with community health service institutions. Various dimensions of responsiveness within Henan province community health service institutions are determined through a multiple-input pecking order graph. The fuzzy comprehen-sive evaluation method is used to evaluate the level of responsiveness. Responsiveness inequality index is used to measure the distribution of reactions. Results:A total of 431 valid key informants were surveyed. The various dimensions of the questionnaire of Cronbach alpha coefficient was greater than 0. 623;the total scale of the Cronbach alpha coefficient was 0. 850;the correlation coefficient of each dimension of test-retest reliability were greater than 0. 907. The levels of responsive-ness and distribution index were 8. 33 and 0. 2744, respectively;each dimension by order of importance:timely attention>dignity>infrastructure>communication>confidentiality >social support >selective >autonomy. Approximately 50% of key informants considered that vulnerable groups in community health service institutions were sometimes or often treated unfairly. Conclusion:Key informants considered the responsiveness level of overall higher community health service institu-tions in Henan Province was high, and the distribution of responsiveness was relative equilibrium. However, there is a large shortage of infrastructure, privacy protection, doctor-patient communication, etc.

Objective To investigate the effects of soluble components derived from bone marrow mesenchymal stem cells (BMSCs) on the expression of vascular endothelial growth factor (VEGF) and liver regeneration caused by 70％ portal branch ligation (PBL) in rats.Methods Isolated and cultured BMSCs were lysed by sonication.PBL was performed in male SD rats followed by splenic injection of BMSCs or PBS as control.Animals were analyzed for liver regeneration index,hepatocytes proliferation,hepatic function,histopathological changes,and hepatic genes expression.Expression of VEGF was assessed by Western blot and immunohistochemistry.Results The liver regeneration index increased in the BMSCs group especially 2 and 5 days after PBL compared with the control group (P＜0.05) and reached (51.71±1.62)％ and (76.82±0.81)％ respectively.A 2-fold increase was showed in the PCNA labeling index of hepatocytes in rats treated with BMSCs compared with the control group (P＜0.05).Histopathological findings showed that vacuolar change and sinusoidal congestion were lower in the BMSCs group.Alanine transaminase (ALT) and Aspartate transferase (AST) showed no significant difference between the two groups (P＞0.05).On post operation day 2,hepatic interleukin-6 (IL6),tumor necrosis factor α (TNFα),hepatocyte growth factor (HGF),vascular endothelial growth factor A (VEGFA),and vascular endothelial growth factor 2 (VEGFR2) mRNAs tended to increase in the BMSCs group (P＜0.05) while transforming growth factor β1 (TGFβ1) mRNA decreased (P＜0.05).Western blot showed that the expression level of VEGF in the two groups were equal 2 and 5 days after surgery (P＞0.05).On day 2 post operation,positive VEGF immunoreactivity was present in both pericentral and periportal hepatocytes in the BMSCs group,while only in periportal hepatocytes in the control group.Conclusion These results demonstrate that BMSCs accelerated liver regeneration caused by PBL,which may result from hepatoprotection,enhanced hepatocyte proliferation,and VEGF-mediated angiogenesis early after the operation,potentially creating a new avenue for the study of hepatic regeneration.

Objective To investigate the level of serum cancer antigen 125 (CA125) and lactic dehydrogenase(LDH) and clinical features of patients with non-Hodgkin lymphoma(NHL), and the correlation between the level of serum CA125 and LDH. Methods Forty patients with NHL were studied and the variances of the serum CA125, LDH level before treatment were analysed. Results A higher serum of CA125was associated with clinical phase,group,hydrothorax and ascites,intemational prognostic index (IPI), and had weaker positive correlation to LDH. Conclusion Measurement of serum CA125 had important clinical significance to the patients with NHL especially to the patients with hydrothorax and ascites.

Objective To investigate the effect of the operational treatment for periampullary carcinoma.Methods The data of 53 operative patients were retrospectively analyzed. Among the 24radical operations, PD was performed in 23 cases ,PPPD in 1 ;the palliative operation was performed in 29 cases. Results Among the 24 radical operaions, the overall mortality was 8.3% (2/24), no operational death. The postoperative morbidity was 15 cases,including 5 cases of pancreatic fistula. Median length of hospital stay was 26 days. Conclusion Continual improvement of operative technique and sufficient perioperative management were the keys to increasing the effect of the operational treatment.

The assessments of oocyte quality were usually needed in assisted reproductive technology and reproduction science.Based upon the changes of structure and biochemistry in the development of oocyte,assessments of oocyte quality mainly comprised the oocyte morphology and its maturity.The assessment method of oocyte quality from nondestructive manner and invasive technique to provide multi-pathway for evaluating the oocyte quality reasonable was discussed.

Objective To explore the effects of simvastatin on the protein expressions of urokinase-typeplasminogen activator (uPA) and plasminogen activator inhibitor-1 (PAI-1). Methods Male Sprague–Dawley rats were divided into saline group , LPS group and LPS plus simvastatin group , and were then pretreated with simvastatin (1 mg/kg) for 30 minutes before addition of LPS (8 mg/kg). Changes in left ventricular pressure were recorded. Ninety minutes after LPS injection, whole blood was collected from the inferior vena cava, and neutrophils were separated. The neutrophils were then lysed to detect levels of uPA and PAI-1. Results Left ventricular systolic pressure (LVSP: mmHg), maximal differential of left ventricular pressure (+dp/dtmax:mmHg/s), and heart rate (beats/min) were markedly decreased at different time points after administration of LPS, and maximal differential of left ventricular pressure increased in the rats receiving LPS as compared with those receiving saline, although the differences between the control and LPS groups were not statistically significant. LPS caused a great decline in uPA content and an elevation in PAI-1 content in neutrophils, but simvastatin diminished the impact of LPS on neutrophils. Conclusion Simvastatin plays a role in protection of cardiac function in rats with LPS-induced septic shock , and controls expressions of uPA and PAI-1 in neutrophils.

Objective To assess the value of diffusion weighted imaging (DWI) in monitoring therapy effect of neoadjuvant chemotherapy (NAC) in patients with locally advanced breast cancer.Methods The prospective study included 26 lesions in 24 patients with LABC undergoing NAC.MRI was conducted before chemotherapy,after the first cycle of chemotherapyand after all cycles,including conventional MRI and DWI.All patients were confirmed by pre-treatment fine needle aspiration biopsy (FNAB),and postoperative histopathological prout.All lesions were divided into two groups of pathological complete response (pCR) and non-pCR.We evaluated ADC value and its changes in pathological complete response difference between the groups and complete remission in each testing point.Results Before chemotherapy and after the first cycle of chemotherapy,the ADCmean andADCmin had no statistically significant difference hetween pathologic complete response group and non-complete remission.After the whole chemotherapy,both of them had statistically significant difference;pathological complete response (pCR) and non-pCR early ADCmin value rate were (16.78 ± 22.70) ％ and (12.37 ± 10.09) ％respectively.No statistically significant difference was seen (P =0.53).Preoperative ADCmin value rates were (91.41 ± 45.83) ％ and (29.74 ± 22.96) ％ respectively,which were statistically significant (P =0.00) Conclusion ADC which is measured from DWI can be used to assess early response to NAC in breast cancer lesion,but cannat predict pCR or non-pCR for all cycles of chemotherapy on the first cycle.
