BACKGROUND:Caffeic acid phenethyl ester (CAPE) can inhibit lipid peroxidation after rat brain injury. However, the trend of 5-lipoxygenaseis (5-LOX) and cysteinyl leukotrienes (CysLTs) in model of Parkinson’s disease, and whether CAPE protects against rotenone-induced cel ular injuries by inhibiting the levels of 5-LOX and CysLTs stil need further research.
OBJECTIVE:To investigate the protective effect of CAPE on the rotenone-induced Parkinson-like injury, and to determine whether 5-LOX involved.
METHODS:(1) PC12 cel s in good-growth were col ected and divided into five groups cultured with different concentrations of rotenone (0, 0.01, 0.1, 1, 10μmol/L). 24 and 48 hours later, changes of cel ular morphology and activity were observed to single out the optimum concentration of rotenone;at 24 hours, the levels of 5-LOX and CysLTs were detected by western blotting and ELISA, respectively. (2) PC12 cel s were pretreated with different concentrations of CAPE (0, 0.01, 0.1, 1, 10 μmol/L) for 30 minutes, and 1 μmol/L rotenone was then added. The other cel s received no intervention as blank control group. Subsequently, the cel activity was detected, and the CysLTs production was detected by ELISA at 24 hours.
RESULTS AND CONCLUSION:(1) Rotenone (0.1-10μmol/L) could induce PC12 cel injury with overt morphological and cel activity changes at 24 hours, especial y the 1 μmol/L rotenone. (2) Rotenone also significantly increased the 5-LOX expression and CysLTs production in a concentration-dependant manner. (3) CAPE (1-10μmo/L) significantly attenuated rotenone-induced CysLTs production and cel viability reduction in a concentration-dependant manner. (4) These results suggest that CAPE protects against PC12 cel injuries in the model rat with Parkinson’s disease induced by rotenone involving 5-Lox.

OBJECTIVETo evaluate digital rectal examination (DRE) , transrectal ultrasonography (TRUS) , free/total (f-PSA/ t-PSA) prostate-specific antigen (PSA), and PSA density (PSAD) in the diagnosis of prostate cancer (PCa) in patients with PSA < or = 4.0 microg/L.
METHODSBetween April 1996 and December 2012, a total of 343 subjects, aged 30 -91 years, with PSA < or =4.0 microg/L and abnormal findings on DRE or TRUS underwent prostatic biopsy. Based on the levels of PSA, the subjects were divided into four groups: 0 -1.0, 1.1 -2. 0, 2.1 -3. 0, and 3.1 -4.0 microg/L. The diagnostic values of DRE, TRUS, f-PSA/t-PSA, and PSAD were assessed in those with different PSA levels. According to the age, the subjects were again divided into five groups: C49 yr, 50 -59 yr, 60 -69 yr, 70 -79 yr, and > 80 yr. The rates of PCa detection in relation to PSA levels were estimated in different age groups.
RESULTSOf the 343 subjects, 65 (19.0% ) were diagnosed with PCa, with detection rates of 16.28% (21/129) , 17. 17% (17/99), 21.82% (12/55), and 25.00% (15/60) in those with the PSA levels of 0 -1.0, 1.1 -2.0, 2.1 -3.0, and 3.1 -4.0 microg/L, respectively. There were statistically significant differences in f-PSA/t-PSA between the PCa patients and non-PCa subjects with the PSA level > 2.0 microg/L (P <0.05) , but not with the PSA level < or =2.0 microg/L (P > 0.05) , nor did PSAD show any significant difference between the PCa and non-PCa groups ([0.09+/-0. 16] versus [0. 06 +/- 0. 07] micro/L/ml, P > 0. 05). The rate of cancer detection rose -with the elevation of the PSA level, but had no statistically significant difference among different age groups (P >0.05).
CONCLUSIONPSA 2.1 -4.0 microg/L with abnormal DRE and TRUS findings should be considered as a warning signal, which requires regular follow-up and PSA detection. With f-PSA/t-PSA <0. 15 with or without abnormal DRE and TRUS findings, routine prostate biopsy should be performed. PCa diagnosis cannot be effectively established by DRE, TRUS, f-PSA/t-PSA, and PSAD in those with PSA < or = 2.0 microg/L.

Along with the development of computer techniques and the dissemination of Internet,many investigators of microorganisms already can acquire a lot of knowledge of many fields on microbe via Internet,extremely including the whole genome of a certain microbe. This was considered unimaginable in the past.Rapid collection of information also to a great extent expands the researching ranges and researching ability of microbial researcher,and at one time,the highly developed Internet provides a unprecedented opportunity for intercommunication of information?share of resources and international cooperations of microbiology.

Objective To investigate the etiology of iatrogenic bile duct injury and experience in its diagnosis and treatment. Methods A retrospective study was conducted on the clinical data of 86 patients with iatrogenic trauma in the bile duct. Results These 86 cases have received a total of 156 sessions of surgical procedures, including 2 explorations in 66 cases,3 explorations in 6 cases. Lateral bile duct injury in 22 cases was treated by suture repair and T tube stent. Eight cases suffering from iatrogenic transection of the common bile duct were retrieved by cholangiojejunostomy and T tube stent. Nine cases with inadvertent CBD ligature were managed by a lysis and T tube stent. Roux en Y cholangiojejunostomy was adopted in 77 cases. Sixty cases were followed up for 1~10 years, with good result in 90% of the cases. Conclusions Most CBD iatrogenic injury cases were encountered as a result of cholecystectomy.Roux en Y cholangiojejunostomy is the choice of therapy.

Objective To investigate the effects of mild hypothermia ( MH ) on the expression of my- eloperoxidase(MPO) and cyclooxygenase 2 (COX 2) in rats after cerebral ischemia and reperfusion (CIR). Methods Forty-eight Wistar rats were randomly divided into four control groups (n=6 in each) and four MH groups (n=6 in each).CIR models were established by suture occlusion of the left middle cerebral artery.The rats in the MH groups,but not in the control groups,were treated with MH.Rats were killed at 4 h,8 h,12 h and 16 h after CIR.MPO expression was measured,along with the expression of COX 2 as measured by Western blot- ting and immunohistochemical methods.Results Compared with the control groups,MPO activity and the COX 2 expression in the cortex and striatum were significantly lower in all the MH groups at 4 h,8 h,12 h and 16 h after CIR.Conclusion MH treatment can protect neurons by decreasing MPO activity and COX 2 expression,allevia- ting inflammation and reducing secondary injuries after CIR.
