OBJECTIVETo investigate the dynamic changes of neurofilament contents in rat's spinal cord induced by 2, 5-hexanedione (2, 5-HD), and explore the molecular mechanism of n-hexane neuropathy.
METHODSMale Wistar rats were administered at a dosage of 400 mg/kg/day 2, 5-HD for 2, 4 and 8 weeks respectively. HD-induced neurological defects were detected and quantified using gait score, and the relative lev-els of NF-H, NF-M, and NF-L in spinal cords of rats were determined by Western Blotting.
RESULTSExposure to 2, 5-HD produced progressive gait abnormalities, which suggested that the rat model of 2, 5-HD-induced neurotoxicity was established successfully. Western-Blotting results showed that NFs content in spinal cord demonstrated a progressive decline as the intoxication continued. In the supernatant fraction, compared to the controls, NF-H con-tent decreased by 15.7%, 57.0%, and 58.0% respectively after 2, 4, and 8-week treatment with 2, 5-HD (P < 0.01); accordingly, NF-M decreased by 36.0%, 61.3%, and 65.2% respectively (P < 0.01); NF-L decreased by 20.8%, 43.9%, and 44.3% respectively (P < 0.01). In the pellet fraction, the contents of NF-H in groups of 4 and 8 weeks' exposure to HD decreased by 35.6% and 43.2%, respectively (P < 0.01), and those of NF-L decreased by 26.4% and 42.1%, respectively (P < 0.01) when compared to the control. Further-more, NF-M contents in groups of 2, 4 and 8 weeks' exposure decreased by 23.3%, 33.9%, and 63.7% respectively (P < 0.01). The NFs level in spinal cords was highly correlated with gait abnormality of treated rats as the intoxication went on. Multiple correlation coefficients of NF-H, NF-M, and NF-L content with gait score of HD-treated rat were 0.8912, 0.9282 and 0.8981 (P < 0.01) respectively.
CONCLUSIONThe declines of NFs are high-ly related to neurobehavioral abnormality of 2, 5-HD-treated animals, and involved in the development of n-hexane neuropathy.

Objective To explore the indications for percutaneous renal biopsy of asymptomatic hematuria in children. Methods The renal pathological types of 485 children with asymptomatic hematuria were analyzed retrospectively. According to the degree of hematuria and whether or not combined with proteinuria, the children were divided into microscopic hematuria group, gross hematuria group and hematuria with proteinuria group. The microscopic hematuria group was further divided into urine red blood cell<15/HPF group, (15~30)/HPF group, and >30/HPF group according to hematuria degree. Results In 227 males and 258 females with the average age of 7.23±2.93 years, there were 318 cases in microscopic hematuria group, in which the most common pathological types were minor lesions (64.8%), followed by focal glomerular lesions (16.7%) and focal segmental glomerulosclerosis (8.2%). There were 119 cases in gross hematuria group, in which the most common pathological types were also minor lesions (26.1%), followed by IgA nephropathy (24.4%) and mesangial proliferative glomerulopathy (20.2%). There were 48 cases in hematuria with proteinuria group, in which the most common pathological types were IgA nephropathy (29.2%) and minor lesions (29.2%). The distribution of the pathological types among microscopic hematuria group, gross hematuria group and hematuria with proteinuria group were statistically different (χ2=152.03, P<0.001). In three groups, microscopic hematuria group had the highest proportion of minor lesions, while gross hematuria group and hematuria with proteinuria group had higher proportion of IgA nephropathy and mesangial proliferative glomerulonephritis . In microscopic hematuria group, there were 149 children with urine red blood cell<15/HPF, 96 with urine red blood cell (15~30)/HPF, and 73 with urine red blood cell >30/HPF. There was no difference in pathological types among three sub-groups (χ2=15.18, P=0.51), and mild lesions were the most common pathological types in each group. Conclusion Renal biopsy should be performed at earliest possible time to make pathological diagnosis in asymptomatic hematuria children with gross hematuria or proteinuria.

BACKGROUNDType 1 diabetes has been recognized as an organ specific autoimmune disease owing to the immune destruction of pancreatic islet beta cells in genetically susceptible individuals. In both human and rodent models of type 1 diabetes, such as nonobese diabetic (NOD) mice, biobreeding rats, the disease has a distinct stage characterized by immune cells infiltrating in the pancreas (insulitis). The major populations of infiltrating cells are macrophages and T lymphocytes. Therefore, immune cell infiltration of pancreatic islets may be a crucial step in the pathogenesis of type 1 diabetes. Monocyte chemoattractant protein-1 can specifically attract monocytes in vivo. Interferon induced protein-10 has chemoattractant effects on the activated lymphocytes. In this study, we analysed the expression of monocyte chemoattractant protein-1 in the pancreas of mice and interferon inducible protein-10 mRNA in the pancreas of NOD mice, and discussed their possible role in the pathogenesis of type 1 diabetes.
METHODSThe immunohistochemical method and immunoelectronmicroscopy were used to evaluate the expression of monocyte chemoattractant protein-1 in the pancreas of NOD mice and BALB/c mice. RT-PCR was used to evaluate the expression of monocyte chemoattractant protein-1 and interferon inducible protein mRNA in NOD mice.
RESULTSMonocyte chemoattractant protein-1 was positive in the pancreas of NOD mice, whereas negative in the pancreas of BALB/C mice. RT-PCR showed that monocyte chemoattractant protein-1 and interferon inducible protein-10 mRNA could be found in the pancreas of NOD mice. Immunoelectronmicroscopy demonstrated that monocyte chemoattractant protein-1 was produced by beta cells and stored in the cytoplasm of the cells.
CONCLUSIONSPancreatic islet beta cells produce monocyte chemoattractantprotein-1 in NOD mice. Monocyte chemoattractant protein-1 may play an important part in the pathogenesis of type 1 diabetes by attracting monocytes/macrophages to infiltrate pancreatic islets.

This study was purposed to investigate the immune reconstitution of T-cells in patients who received haploidentical hematopoietic stem cell transplantation (hiHSCT). The peripheral blood was harvested from 22 patients before transplantation and at month 1, 3, 6 after hiHSCT. The proportions of T lymphocyte subtypes including CD3(+), CD4(+), CD8(+), CD45RO(+), and CD45RA(+)CD62L(+) were analyzed by flow cytometry, followed by the calculation of T cell numbers according to the amounts of peripheral blood leukocytes. Adenosine triphosphate (ATP) value in CD4(+) T cells was measured by ImmuKnow method to evaluate the function of lymphocytes. The results showed that the CD3(+) cell absolute value before transplantation was 833.75 ± 359.84/µl, but those values at month 1, 3, 6 after transplantation were 318.87 ± 266.71/µl, 1006.76 ± 512.32/µl and 1296.38 ± 958.77/µl respectively. The CD4(+) cell absolute value before transplantation was 336.99 ± 211.11/µl, but such values at month 1, 3, 6 after transplantation were 45.89 ± 44.21/µl, 142.97 ± 114.85/µl, and 181.78 ± 120.61/µl respectively. The CD8(+) cell absolute value before transplantation was 430.21 ± 159.48/µl, but those values at month 1, 3, 6 after transplantation were 230.44 ± 195.89/µl, 621.64 ± 318.83/µl, and 823.07 ± 633.55/µl respectively. The CD4(+)CD45RO(+) memory T cell absolute value before transplantation was 227.44 ± 73.34/µl, but such values at month 1, 3, 6 after transplantation were 43.47 ± 43.40/µl, 138.69 ± 110.17/µl, 147.73 ± 82.94/µl respectively. The CD8(+)CD45RO(+) memory T cell absolute value before transplantation was 212.70 ± 98.48/µl, but such values at month 1, 3, 6 after transplantation were 184.76 ± 168.65/µl, 445.90 ± 252.50/µl, 519.80 ± 475.53/µl respectively. CD4(+)CD45RA(+)CD62L(+) naive T cell number before transplantation was 68.94 ± 59.74/µl, but such cell numbers at month 1, 3, 6 after transplantation decreased to 2.44 ± 2.93/µl, 3.14 ± 3.48/µl, 23.22 ± 38.38/µl respectively. The CD8(+)CD45RA(+)CD62L(+) naive T cell absolute value before transplantation was 124.82 ± 60.95/µl, but those values at month 1, 3, 6 decreased to 19.37 ± 17.71/µl, 76.63 ± 50.85/µl, and 114.49 ± 174.29/µl respectively. The ATP value in CD4(+) T cells decreased to 210.19 ± 119.37 ng/ml at month 1 after transplantation and increased to 280.62 ± 110.03 ng/ml at month 3, and 357.28 ± 76.18 ng/ml at month 6 after transplantation. It is concluded that CD8(+) memory T cell reconstruction contributes critically to T cell recovery early after hiHSCT, while the thymic output function remains low. However, T cell function recovers to normal range at month 3 after transplantation.

OBJECTIVETo investigate the expression features of glypican-3 (GPC-3) and its diagnostic and differential values in hepatocellular carcinoma (HCC).
METHODSRat hepatoma models were made and the dynamic expression features of GPC-3 protein and its gene were investigated by Western blotting and RT-PCR respectively. Liver specimens from 36 HCC patients were collected by self-control method and the expression and clinicopathological features of GPC-3 were analyzed by immunohistochemistry. Serum GPC-3 levels were quantitatively detected by ELISA and its efficiency for HCC diagnosis was evaluated in patients with liver diseases.
RESULTSThe incidence of GPC-3 was 0% in control, 83.3% in degeneration, 100% in precancerosis and 100% in canceration during dynamic formation of rat hepatoma, respectively. The positive GPC-3 was brown granule- like staining localized in membrane and cytoplasm in human HCC.
CONCLUSIONSThe GPC-3 positive rates were 80.6% in HCC, 41.7% in surrounding tissues and none in distal tissues (P < 0.01), respectively. No positive relationship presented between GPC-3 and differentiation grade or the number of tumor except of tumor size (Z = 2.941, P < 0.01). The incidence of serum GPC-3 was 52.8% in HCC patients except of one patient with cirrhosis. No significant differences were found between GPC-3 and sex, age, AFP, tumor number, Child classification or extrahepatic metastasis except of tumor size (χ² = 6.318, P < 0.05) and HBV infection (χ² = 23.362, P < 0.01). Combined detection of GPC-3 and AFP could rise up diagnosis of HCC. GPC-3 expression closely associated with HCC and might be useful for early diagnosis of HCC.

This study was undertaken to explore the myocardioprotective effects of the combination of ischemic preconditioning (IP) with hypothermia and St.II Thomas crystalloid cardioplegic solution (CCS) on immature hearts in the rabbit. Isolated immature rabbit hearts were perfused with Krebs-Henseleit bicarbonate buffer on Langendorff apparatus. In experiment 1, 24 hearts were divided into 4 groups (n=6 in each group): Con, IP1, IP2 and IP3 group. Hearts of the four groups underwent 0, 1, 2 or 3 cycles of IP respectively. Then all the hearts were subjected to a sustained ischemia period of 2 h at 20 degrees C and a postischemic reperfusion period of 30 min at 37 degrees C. In experiment 2, 48 hearts were divided into 6 groups (n=8 in each group): SCon1, SIP1, SCon2, SIP2, SCon3 and SIP3 group, according to hypothermia and the duration of sustained ischemia (30 min at 32 degrees C; 90 min at 25 degrees C, 2 h at 20 degrees C). The SIP1, SIP2 and SIP3 groups were preconditioned twice before the sustained hypothermic ischemia, while the SCon1, SCon2 and SCon3 groups were not preconditioned. CCS was applied during sustained ischemia, all the hearts were reperfused for 30 min at 37 degrees C. Heart rate (HR), left ventricular developed pressure (LVDP) and peak rate of increase or decrease of left ventricular pressure (+/-dp/dt(max)) were recorded. Tissue concentration of adenosine triphosphate (ATP), malondialdehyde (MDA) and the activity of superoxide dismutase (SOD) were measured. At the end of reperfusion, values of product of LVDP and HR, +/-dp/dt(max) in IP2 group were 96%+/-21%, 101%+/-19% and 84% +/-15% of the baseline values respectively, which were significantly higher than those of Con group and IP3 group (P<0.01, P<0.05); also, the ATP content of IP2 group was higher than that of the Con group (P<0.01). When CCS was applied during sustained period of hypothermic ischemia at 32 degrees C or 25 degrees C, recovery rates of RPP (rate product, =LVDPxHR) and +dp/dt(max) in SIP1 group were 87% +/-14% or 99% +/-26% of the baseline values respectively (P<0.05, vs SCon1 group), the values in SIP2 group changed to 87% +/-16% or 102% +/-20% respectively (P<0.05, vs SCon2 group). Contents of ATP in SIP1 and SIP2 groups were significantly higher than those of SCon1 or SCon2 groups respectively (P<0.05), but MDA content of the two groups were significantly lower than those of SCon1 or SCon2 groups (P<0.05) respectively. The study indicates that IP attenuates hypothermic ischemia/reperfusion injury to immature rabbit hearts under 20 degrees C ischemia, two cycles of IP showing better myocardioprotective effects than 1 or 3 cycles of IP. When IP was combined with CCS which were applied during hypothermic ischemia period, the beneficial effects of IP were weakened as the temperature during the hypothermic period was elevated.

PURPOSE: To investigate and compare the effects of propofol and midazolam on inflammation and oxidase stress in children with congenital heart disease undergoing cardiac surgery. MATERIALS AND METHODS: Thirty-two ASA class I-II children with congenital heart disease undergoing cardiac surgery were randomly divided into two groups: propofol combined with low dose fentanyl (PF group, n = 16) and midazolam combined with low dose fentanyl (MF group, n = 16). Tracheal extubation time and length of Intensive Care Unit (ICU) stay were recorded. Blood samples were taken before operation (T0), at 2 h after release of the aorta cross-clamp (T3) and at 24 h after operation (T4) to measure interleukin 6 (IL-6), IL-8, superoxide dismutase (SOD) and malondialdehyde (MDA) levels. Myocardium samples were collected at 10-20 min after aorta cross-clamp (T1) and at 10-20 min after the release of the aorta cross-clamp (T2) to detect heme oxygenase-1 (HO-1) expression. RESULTS: Tracheal extubation time and length of ICU stay in PF group were significantly shorter than those of the MF group (p < 0.05, respectively). After cardiopulmonary bypass, IL-6, IL-8 and MDA levels were significantly increased, and the SOD level was significantly reduced in both two groups, but PF group exhibited lower IL-6, IL-8 and MDA levels and higher SOD levels than the MF group (p < 0.05, respectively). The HO-1 expression in the PF group was significantly higher than that in MF group at the corresponding time points (p < 0.05, respectively). CONCLUSION: Propofol is superior to midazolam in reducing inflammation and oxidase stress and in improving post-operation recovery in children with congenital heart disease undergoing cardiac surgery.
