The hypertension is one of chronic vascular diseases, which often implicates multiple tissues causing stroke, cardiac hypertrophy, and renal failure. A growing body of evidence suggests that inflammatory mechanisms are important participants in the pathophysiology of hypertension. In this study, the inflammatory status of these tissues (kidney, liver, heart, and brain) in spontaneously hypertensive rats (SHR) was analyzed and its molecular mechanism was explored. The tissues were dissected from SHR and age-matched control Wistar-Kyoto (WKY) rats to investigate the abundance of inflammation-related mediators (IL-1beta, TNFalpha, ICAM-1, iNOS, C/EBPdelta and PPARgamma). mRNA levels were determined by reverse transcription-polymerase chain reaction and protein expression was evaluated by Western blot. To evaluate the oxidative stress of tissues, carbonyl protein content and total antioxidant capacity of tissues were detected by spectrophotometry and ferric reduction ability power (FRAP) method. The results suggest that: (1) Expressions of inflammation-related mediators (IL-1beta, TNFalpha, ICAM-1, iNOS, C/EBPdelta and PPARgamma) in SHR were higher compared with those in WKY rats except no evident increase of IL-1beta mRNA in liver and brain in SHR. (2) Tissues in SHR contained obviously increased carbonyl protein (nmol/mg protein) compared to that in WKY rats (8.93+/-1.08 vs 2.27+/-0.43 for kidney, 2.23+/-0.23 vs 0.17+/-0.02 for heart, 13.42+/-1.10 vs 5.72+/-1.01 for brain, respectively, P<0.05). However, no evident difference in the amount of carbonyl protein in liver was detected between SHR and WKY rats. (3) Total antioxidant capacities of kidney, liver, heart and brain were markedly lower in SHR than that in WKY rats (P<0.05). Thus, the present data reveal a higher inflammatory status in the important tissues in SHR and indicate that inflammation might play a potential role in pathogenesis of hypertension and secondary organ complications.

BACKGROUNDNR2B containing N-methyl-D-aspartate (NMDA) receptor plays an important role in the facilitation and maintenance of neuropathic pain. The discrete distribution of NR2B subunit in the central nervous system (CNS) may support reduced side effects of agents that act selectively at this site. Therefore, we investigated the hypothesis that a humoral autoimmune response targeting the NR2B subunit of NMDA receptor relieves pain like behaviours produced by peripheral injury.

METHODSRats were immunized subcutaneously with NR2B-Keyhole Limpet Hemocyanin (NR2B-KLH) three times at two-week intervals. NR2B specific IgG titres in sera and cerebrospinal fluid were determined by indirect ELISA. Seven days after the third immunization, 2 of the 3 terminal branches of the sciatic nerve (tibial and common peroneal nerves) were tightly ligated. Behavioural testing was carried out on every other day after surgery, until 7 days after surgery. The lumbar spinal cord (L4-6) was removed on day 7 after ligation. The expression of NR2B protein in the lumbar spinal cord was determined using Western blotting.

RESULTSAfter the second vaccination, NR2B specific IgG in sera was detected to be > 0.5 microg/ml in six of nine rats. After the third vaccination, all the immunized rats had > 2.2 microg/ml. Titres of NR2B specific IgG in sera peaked 42 days post initial immunization and persisted for over 70 days. No NR2B specific IgG was detected in sera from PBS or KLH group. The behavioural thresholds in NR2B group were significantly higher than those in PBS and KLH groups on day 7 after ligation. NR2B specific IgG in CSF in NR2B group could not be detected on day 1 before spinal dissection; but could be detected on day 7 after surgery. The expression of NR2B protein in group NR2B was significantly lower than in PBS and KLH groups on day 7 after surgery.

CONCLUSIONThe NR2B peptide could be used as a vaccine against neuropathic pain, which could be associated with reduction of NR2B protein in the lumbar spinal cord.

OBJECTIVETo investigate the relative factors for hidden blood loss (HBL) after primary total knee arthroplasty (TKA).

METHODSA retrospective study of 422 consecutive patients who underwent primary TKA between October 2007 and August 2009 was carried on. There were 60 male and 362 female patients with a mean age of 65.7 years. The HBL was calculated according to Gross formula. The effect of patient gender, age, body mass index (BMI), pre-operative diagnosis, unilateral or simultaneous bilateral TKA, tourniquet time, type of prosthesis, postoperative anticoagulation method and deep vein thrombosis (DVT) on the postoperative HBL were analyzed.

RESULTSThe HBL in patients underwent unilateral TKA was significantly lower than that in those underwent simultaneous bilateral TKA [(1284 ± 207) ml vs. (2248 ± 504) ml, P = 0.000]. Unvaried analysis showed that the HBL were associated with BMI, tourniquet time, prosthesis type and postoperative anticoagulation method. Multivariate linear regression analysis showed that the impact factors of postoperative HBL include BMI, tourniquet time and prosthesis type.

CONCLUSIONSBMI, bilateral simultaneous TKA, tourniquet time and intercondylar open prosthesis impact the HBL after primary TKA. However, the influence of gender, age, diagnosis, postoperative anticoagulation method and DVT on the HBL are not significant.

This study was aimed to investigate the expression of c-MPL in acute myeloid leukemia (AML) and the correlation of the c-MPL expression with CD34 and CD38, so as to define the expression of c-MPL in leukemic stem cells. The expression levels of CD34, CD38 and c-MPL were detected by flow cytometry in bone marrow cells from 29 newly diagnosed AML patients. The relationship of c-MPL positive cell ratio with clinical parameters and correlation of c-MPL with CD34 and CD38 expression in AML patients were analyzed. The results showed that expression level of c-MPL in AML patients was significantly higher than that of normal controls (P < 0.05), and the expression level of c-MPL did not correlate with age, sex, white blood cell count, AML1-ETO fusion gene and remission after chemotherapy, but the expression of c-MPL in M2 and M5 patients was higher than that of normal control (P < 0.05). Expression of c-MPL in CD34 positive AML patients was obviously higher than that in CD34 negative AML patients (P < 0.01). c-MPL was significantly higher expressed in CD34(+) cells than that in CD34(-) cells (P < 0.001), while c-MPL expression was not significantly different between CD34(+)CD38(-) and CD34(+)CD38(-) cell groups. Positive correlation between c-MPL and CD34 expression was observed (r = 0.380, P = 0.042). It is concluded that expression of c-MPL is higher in AML patients, and positively correlates with the expression level of CD34. The c-MPL expresses in leukemic stem cells.

OBJECTIVESTo explore the relation of ultrasonic findings to pathological features in cases of chronic viral hepatitis B and C.

METHODSThe ultrasonic and pathological findings were analyzed in 130 patients with chronic viral hepatitis B and 106 with chronic viral hepatitis C.

RESULTSIn patients with hepatitis B, the ultrasonic echo was thicker and more intensive and uneven cords were found. These findings were closely related to the pathological findings (P less than 0.001). In those with hepatitis C, the ultrasonic echo was slight and dense, which was also closely related to the pathological findings (P less than 0.001). In the patients complicated with fatty liver, the ultrasonic findings were also different (P less than 0.001).

CONCLUSIONUltrasonography is helpful for differential diagnosis of hepatitis B and hepatitis C.

The production of human recombinant proteins in milk of transgenic farm animals offers a safe, very cost-effective source of commercially important proteins that cannot be produced as efficiently in adequate quantities by other methods. This review has summarized the current status of gene selection, vector construct, transgenic methods, economics, and obvious potential in transgenic animals bioreactors. Recently, a more powerful approach was adopted in the transgenic animals founded on the application of nuclear transfer. As we will illustrate, this strategy presents a breakthrough in the overall efficiency of generating transgenic farm animals, product consistency, and time of product development. The successful adaptation of Cre-/lox P-mediated site-specific DNA recombination systems in farm animals will offer unprecedented possibilities for generating transgenic animals.

Objective To investigate the relationship between benign prostatic hyperplasia (BPH) andchronic prostatitis(CP). Methods Three hundred BPH patients were studied, aged from 51 to 96 (aver-age 72). All patients were divided into 3 groups (Ⅰ°、Ⅱ°and Ⅲ°)according to result of digital rectal examina-tion, which include 85 cases , 139 cases and 76 cases respectively. The incidence of CP among 3 groups were compared and analyzed. Results Two hundreds and thirty-five of the 300 cases with BPH were accompa-nied with CP(77.7%). Among the 233 cases, 53 cases were in Ⅰ degree BPH group (53 / 85, 62.4% ), 113 cases were in Ⅱ degree BPH group (113/139, 81.3%), 67 cases were in Ⅲ degree BPH group (67/76, 88.2%). Conclusions Many BPH patients were accompanied by CP. The prostate size and the inflamma-tion of prostate were positive correlated. The effect of anti-inflammatory treatment in Ⅰ degree and Ⅱ degreeBPH patients was better than Ⅲ degree BPH patients.
