Objective To investigate the changes of NF-κB p65, IL-6 and cell apoptosis in sec-ondary brain injury after traumatic brain injury and the influence of fenofibrate on these parameters in rats. Methods Ninety-eight male Sprague-Dawley ( SD) rats were randomly divided into two groups:fenofibrate group ( n =49) and control group ( n =49) .The fenofibrate group was induced with the improved Feeney method and received intragastrica of lipanthyl 60 mg/(kg? d) immediately after injury.The control group were received intragastrica of sodium chloride injection 2 ml/( kg? d) immediately after injury and twice everyday until rats were killed.Each group was divided into seven subgroups by sacrificed time after injury, those were 1 h, 3 h, 6 h, 12 h, 24 h, 3 d, and 7 d, and each subgroup got 7 rats.Each subgroup was ran-domly selected three rats after being killed to detect expressions of NF-κB p65 and IL-6 of rat contusion peri tissues brain tissues with immunohistochemical method.While using terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling ( TUNEL) method was used to observe the peri cell apoptosis after brain contusion.Results The expressions of NF-κB p65 and the IL-6 in each fenofibrate group were significantly decreased relative to the control group ( P <0.05),and a significant positive correlation between both pa-rameters in two groups ( P <0.01) .At the same time, the number of apoptotic cells was decreased ( P <0.05).Conclusions Fenofibrate was probably through the route of relieving inflammation response to re-duce the change of secondary brain injury after traumatic brain injury and decrease neural cell apoptosis, and then provide protection of neurocytes.

The development of proteomic technique has sparked new focus on novel protein markers for many diseases including cancer. Urine is one of the most useful biofluids for routine testing to provide an ideal resource for the discovery of novel biomarkers, with the advantage over tissue biopsy samples due to the ease and the less invasive nature of urinary collection. This review summarizes urinary protein tumor markers found in prostate cancer, bladder cancer, lung cancer and breast cancer that have shown potential for urogenital and non-urogenital cancer, so as to provide reference on high sensitive and high specific urinary protein tumor markers for early prevention, early diagnosis and treatment of cancer.

SUMMARY Takayasu’s arteritis is a rare,idiopathic,chronic inflammatory disease.Its course is un-predictable,but slow progression is usual,leading to stenosis,occlusion,or aneurismal degeneration of the aorta or its major branches.We present the anesthesia management of pregnancy in four women ad-mitted to Peking University Third Hospital for caesarean section from year 2006 to 2015 complicated with Takayasu’s arteritis and review this disease with special reference to natural history,diagnostic criteria, classification,prognostic factors,and anesthesia considerations.Anesthesiological data were retrospec-tively analyzed for clinical manifestations,anesthesia process,perioperative complications,and pregnan-cy outcome.One patient received only epidural anesthesia,while the other three patients received com-bined spinal and epidural anesthesia (CSEA).Surgeries for all the four patients were successful with sta-ble vital signs.We found comprehensive examinations including whether the disease was in the active phase and the clinical classification of the disease before conception was recommended for patients diag-nosed with Takayasu’s arteritis.CSEA and continuous epidural block could be both used as anesthesio-logical method in patients with Takayasu’s arteritis.During the surgery,to avoid rapid hemodynamic fluctuations and protect the major organs’function is very essential to allow for a satisfactory outcome.

Objective To study the effects of Danshen Shujingwan on cervical cord compression in rats. Methods 60 healthy male SD rats of 8 weeks old were randomly divided into 6 groups: sham group (N group), model group (M group), DSW groups of high, medium and low dosages, and group treated with Jingfukang (J group), with 10 rats in each. The cervical cord compression models were established by transplanted silica gel. From 7 d after model establishments, the rats were respectively treated with drug by gavage for 30 d. They were observed pathologically. Results The extent and scope of damage were less in the treatment groups than in the model group (P<0.001), while the number of normal neurons remained more in the treatment groups (P<0.01).Conclusion DSW can decrease the damage after cervical spinal cord compression, protect the neurons from injuring.

Background and purpose:Tetrandrine is a natural compound whose role in retinoblastoma remains unclear. This study investigated the effects of tetrandrine (Tet) on human retinoblastoma cells.Methods:CCK-8 assays were performed to analyze the effects of Tet on viability of retinoblastoma cells. The apoptosis rate was determined by Annexin V/PI assays. After staining with 2′,7′-dichlorolfuorescin diacetate (DCFH-DA), cellular reactive oxygen species (ROS) was measured by lfow cytometry. Akt and p-Akt were detected by Western blot.Results:Tet inhibited cell viability of retinoblastoma cells. After treatment with Tet (4, 8, 10 and 20μmol/L) for 24h, cell viability inhibition rates of WERI-Rb-I were 5.7%, 25.0%, 55.1% and 84.9%, whereas inhibition rates of Y79 cells were 2.4%,2.9%, 23.8% and 54.2% (P<0.01). In cells treated with 10μmol/L of Tet for 12, 24 and 48 h, cell viability inhibition rates of WERI-Rb-I were 6.0%, 45.5% and 74.7%, whereas inhibition rates of Y79 cells were 2.9%, 19.4% and 43.3% (P<0.01). Tet induced retinoblastoma cell apoptosis. After treatment with Tet (10 μmol/L) for 24 and 48 h, apoptosis rates of WERI-Rb-I were (23.70±1.75)% and (34.83±3.15)%, respectively, whereas apoptosis rates of Y79 cells were (9.62±2.69)% and (14.97±1.50)%, respectively (P<0.01). Apoptosis inhibitor Z-VAD-FMK attenuated Tet-induced cell death (P<0.05). ROS levels were indeed increased in cells treated with Tet (10 μmol/L) for 6 and 12 h (P<0.01), while N-Acetyl-L-cysteine (NAC) decreased Tet-induced ROS (P<0.01). After ROS was inhibited by NAC, apoptosis rate was decreased compared with the control (P<0.01). Further study indicated that Tet inhibited PI3K/Akt pathway in retinoblastoma cells.Conclusion:Tet induces cell apoptosis via increasing ROS synthesis and inhibiting PI3K/Akt pathway.

Objective To study the CT specialities of small lung cancer with the thin-section scan images by general CT machine.Methods Through the 3 mm-scan means in breathless condition,CT specialities of 36 cases of little lung carcinoma were analysed,which were scanned with CT before operation and proved by pathology.Results CT specialities of peripheral small lung cancer had lobular sign(91.6%);coarse spicules sign(77.8%);bubble-like lucency sign(50%);pleural retraction sign(88.9%);honeycomb sign(11.1%);cavity(2.7%);convergence sign of pulmonary vessels(66.7%),the radiative shadiness of pathological pleural side(11.1%).Conclusion The CT specialities are divided into prime and subaltern specialities in the diagnosis of peripheral small lung carinoma.The prime specialities have lobular sign,edge coarse spicules sign,bubble-like lucency sign,pleural retraction sign,convergence sign of pulmonary vessels,and the CT specialities are not agreeable with the small lung carcinoma of different tissue types.
