Objective To explore the value of transcranial Doppler ultrasonography (TCD) on diagnosing the cerebral vasospasm (CVS) following subarachnoid hemorrhage (SAH). Methods TCD was used to detect and monitor the cerebral blood flow status to estimate CVS following SAH in 30 cases, then the results of TCD were analyzed by combining with clinical manifestation and SAH severity on CT. Results 17 patients (56.7%) had the evidence of CVS confirmed by TCD, 10 of them were nonsymptomatic and 7 were symptomatic. The incidences of CVS in patients with Fisher grade Ⅲ and Ⅳ were more higher than gradeⅠandⅡ(P

Objective To investigate the method of the artificial lipofuscin preparation. Methods Extracting the hepatic mitochondrion of rat, we applied oxidation-reduction method to making and obtaining the artificial lipofuscin.The capability of artificial lipofuscin being digested by peritoneal macrophages of mice was examined. Results The artificial lipofuscin had positive reactions both to specific histochemical stain and FITC fluorescence label.Positive granules or fluorescence were present in cytoplasm of the macrophages and its distribution was similar to that of positive control.Conclusion The artificial lipofuscin had the same histochemical character and biological effect as natural lipofuscin, so it could be used as a substitute for anti-senescence research.

Objective To probe into the clinical apply value of sentinel lymph node detection in patients with cervical cancer.Methods 33 patients with cervical cancer underwent SLNS detection by using blue dye or methlene blue 4ml or lymphazurin was injected into the cervix at 4 points around the tumor at the time of radical hysterectomy and bilateral pelvic lymphadenectomy1 tumor characteristics surgical findings and specific locations of lymphatic dye uptake were recorded and correlated with final pathology results.Results Among 33 patients undergone this detection,dye uptake was not seen in 1 patient,dye uptake was seen in 32 patients,the SLNS were successfully detected in 81.25%(26/32);7 patients didn't discriminated SLN,the rate was 21.88%(7/32).There were 6 cases who were discovered pelvic cavity lymph nodes metastases in 26 patients discriminated SLN successfully,in all 12 piece metastases lymph nodes were SLN,sensitivity was 6/6,accuracy was 100%(26/26),fake negative rate was 0.Conclusion Sentinel lymph node dectection by the way of blue dye has more clinical apply value in patients with cervical cancer.

Objective:To investigate the protective effect and potential mechanism of cordycepin on renal proximal tubular cells injury induced by lipopolysaccharide (LPS).Methods:Renal proximal tubular cells NRK-52E were incubated on a cell culture plated at a density of 1×10 5/mL for experiment, then divided into control group (Ctrl group), LPS group (cells were stimulated with 1 mg/L LPS), 10 μmol/L or 20 μmol/L cordycep in intervention groups (LPS+C 10 group and LPS+C 20 group). Cell viability was measured using cell counting kit-8 (CCK-8) reagent. The level of intracellular reactive oxygen species (ROS) was detected by 2',7'-dichlorofluorescin diacetate (DCFH-DA) staining. The protein expressions of inflammatory factors intercellular cell adhesion molecule-1 (ICAM-1), vascular cell adhesion molecule-1 (VCAM-1), interleukin-1β (IL-1β), and nuclear factor-κB (NF-κB) were detected by Western blotting. Results:Compared with the Ctrl group, LPS significantly inhibited NRK-52E cell viability, increased intracellular ROS, and up-regulated the expressions of ICAM-1, VCAM-1, IL-1β and NF-κB. Compared with LPS group, after treated with 10 μmol/L or 20 μmol/L cordycepin, NRK-52E cell viability was significantly increased (Ctrl group as 1: 0.717±0.017, 0.916±0.036 vs. 0.554±0.046) and intracellular ROS level was significantly decreased (Ctrl group as 1: 1.527±0.165, 1.098±0.168 vs. 2.543±0.127), meanwhile the expressions of ICAM-1, VCAM-1, IL-1β and NF-κB were significantly down-regulated [Ctrl group as 1, ICAM-1/GAPDH: 2.364±0.097, 1.561±0.074 vs. 3.101±0.121; VCAM-1/GAPDH: 2.866±0.135, 1.920±0.098 vs. 4.170±0.119; IL-1β/GAPDH: 2.358±0.107, 1.563±0.179 vs. 3.301±0.210; phosphorylation NF-κB p65 (NF-κB p-p65)/GAPDH: 2.559±0.166, 1.596±0.148 vs. 3.183±0.098], the differences were statistically significant (all P < 0.05). Compared with the LPS+C 10 group, the cell activity of LPS+C 20 group was more significant (0.916±0.036 vs. 0.717±0.017, P < 0.01), and the expressions of ICAM-1, VCAM-1, IL-1β, NF-κB were down-regulated more significantly (ICAM-1/GAPDH: 1.561±0.074 vs. 2.364±0.097, VCAM-1/GAPDH: 1.920±0.098 vs. 2.866±0.135, IL-1β/GAPDH: 1.563±0.179 vs. 2.358±0.107, NF-κB p-p65/GAPDH: 1.596±0.148 vs. 2.559±0.166, all P < 0.05).Conclusion:Cordycepin could significantly increase the survival rate of NRK-52E cells, reduce intracellular ROS level, and inhibit inflammation, and the anti-inflammation effect can be related with NF-κB pathway.

Objective To investigate the effect of natural killer (NK) cells treated by serum of severe preeclampsia patient on the function of endothelial cells.Methods Fifteen patients with severe preeclampsia and 15 normal pregnant women from the Obstetrics department,Shengjing Hospital,China Medical University were admitted into this case-control study from January 1,2006 to December 31,2008.NK cells from healthy non-pregnant woman were incubated with 20% serum from severe preeclampsia patients or normal pregnant women for 20 hours.Then,human umbilical vein endothelial cells ( HUVEC) and serum-treated NK cells were co-incubated for 24 hours.Apoptosis of HUVEC was checked by flow cytometry and electronic microscope.Endothelin-1 (ET-1) levels in the supernatants of HUVEC and NK cells were examined by radioimmunologic method.Results In severe preeclampsia group,the percentage of early apoptosis cell (Annexin V-FITC+ /PI+ ) was (23.81±4.79)%,that of late apoptosis cell (AnnexinV-FITC+/PI+ ) was (3.29±1.04) %,while those were (16.59±5.13)% and (2.24±0.72)% respectively in normal pregnant group (P＜0.01).There was no significant difference in dead cells (Annexin V-FITC- /PI+ ).Under electronic microscope,typical morphologic changes of apoptosis were shown in severe preeclampsia group.Level of ET-1 in

OBJECTIVE: Comparative analysis of the clinical curative effect of manipulative reduction and TRV- CRP treatment of BPPV, comfort degree during reset and quality of life improvement. METHOD: One hundred and thirty-two patients with BPPV were randomly divided into two groups ,one group underwent the traditional manip- ulative reduction, the other group with TRV-CRP. DRI and VAS was evaluated in the pre and after treatment and evaluation of the efficacy was conducted. The results of two groups were compared. RESULT: The effective rate of manipulative reduction after a week treatment was 89. 23% and TRV-CRP.was 98. 51%, which was higher in TRV-CRP group than that of the manipulation reduction group(P<0. 05). The comfort degree of the manipulation reduction group was 4. 54±2. 48,higher than the TRV-CRP group which was 5. 48±1. 44 (P<0. 05). The score of DHI showed no significant difference before treatment between manipulation reduction group and TRV-CRP group(P>0. 05), the score of the two groups were decreased after a week of reduction, but the improvement of TRV-CRP group was higher than that of manipulation reduction group(P<0. 05). CONCLUSION The success rate of TRV-CRP was higher than that of manipulative reduction,but manipulative reduction comfort degree was higher than TRV-CRP, the two methods can both improve the quality of life of patients with BPPV. TRV-CRP has many advantages over manipulative reduction, but manipulative reduction is simple with low cost, and the effect is still a great advantage. In clinical work, we should reasonable combine the two methods,so as to improve the cure rate of RPPV.
