OBJECTIVETo investigate the protective effect of Danxuetong injection (DXT, a combination of Danshen and Xueshuantong injections) against testicular ischemia-reperfusion injury following testis torsion/detorsion in rats.

METHODSThirty-two 4-week-old healthy male SD rats were randomly divided into four groups of equal number: sham operation, normal saline, single DXT injection, and successive DXT injection. The rat models of testicular ischemia-reperfusion injury were established by 2-hour 720-degree torsion/detorsion of the unilateral testis. At 6 weeks after modeling, the rats were killed and their testes were harvested for measure- ment of testicular coefficients, sperm counts, sperm motility, and the levels of total anti-oxidative capacity (T-AOC) , superoxide dismutase (SOD) , nitric oxide synthase (NOS) , and malondialdehyde ( MDA) in the testis tissue.

RESULTSCompared with the rats of the normal saline group, those of the single DXT injection and successive DXT injection groups showed significant increases in the testicular coefficient (0.11 ± 0.03 vs 0.35 ± 0.04 and 0.40 ± 0.06, P < 0.05), sperm count ([0.46 ± 0.10] vs [1.44 ± 0.50] and [3.00 ± 1.28] x10(9)/ml, P < 0.05), sperm motility ([13.63 ± 14.04] vs [39.63 ± 5.04] and [76.31 ± 3.67]%, P < 0.05), the activity of SOD (72.76 ± 5.58 vs 116.25 ± 8.83 and 133.20 ± 13.84, P < 0.05), and the level of T-AOC (5.58 ± 1.07 vs 13.34 ± 5.81 and 19.21 ± 5.69, P < 0.05), but a remarkable decrease in the content of MDA (42.38 ± 8.94 vs 20.94 ± 5.65 and 15.02 ± 1.03, P < 0. 05) in the injured testes.

CONCLUSIONDXT can effectively rid the testis tissue of oxygen free radicals, improve sperm count and motility by antioxidation, and protect the testis tissue of prepubertal rats against testicular ischemia-reperfusion injury after testis torsion/detorsion. It also has a protective effect on the contralateral testis, and successive injection has a better effect than single injection of DXT.

Objective To investigate the correlation between the changes of serum S100B protein level in acute phase and the scores of mini-mental state examination (MMSE) in patients with brain concussion, and evaluate the role of serum S100B protein level in the prognosis of cognition disorders after brain concussion. Methods The serum S100B protein level was determined by an enzyme linked immunosorbent assay (ELISA) in 126 cases of brain concussion 6 and 12 h, and 3 d after admission, and these data were compared with those in 96 cases of moderate head trauma without transitory loss of consciousness (admitted to our hospital at the same period, control group). MMSE was performed 1 and 14 d and 3 months after injury, and the correlation between the changes of serum S100B level in acute phase and MMSE scores was observed. Results As compared with that in control group,the serum S100B protein level in patients with brain concussion was significant higher at 6 and 12 h after admission(P＜0.05). The serum S100B protein level at 6 h, but not at 12 h and 3 d after admission, was closely associated with the MMSE scores 1 and 14 d and 3 months after injury. Conclusion Early elevation of S100B within 6 h of admission in patients with brain concussion, obviously correlating with cognitive impairment, may serve as an important prognostic marker in predicting clinical outcome of cognition disorders after brain injury.

OBJECTIVETo investigate the association of gene polymorphisms of Toll-like receptor 3 (TLR3)-1377C/T and expression of TLR3 with the susceptibility to enterovirus 71 (EV71) encephalitis in children.

METHODSA total of 187 children with EV71 infection (59 children in the encephalitis group and 128 in the non-encephalitis group) and 232 children who underwent physical examination were enrolled in the case-control study. Polymerase chain reaction-restriction fragment length polymorphism was used to detect the TLR3-1377C/T gene polymorphisms. ELISA was used to measure the serum level of TLR3.

RESULTSThere were no significant differences in the genotype and allele frequencies of TLR3-1377C/T between the non-encephalitis group and the encephalitis group. Compared with the control group, the encephalitis group and the non-encephalitis group had significant increases in the serum level of TLR3 (P<0.05), and the non-encephalitis group had the highest level (P<0.05). The encephalitis group had a significantly higher EV71 viral load than the non-encephalitis group (P<0.01). The children aged <1 year or ≥1 year in the encephalitis group and the non-encephalitis group had significant increases in the serum level of TLR3 compared with their counterparts in the control group (P<0.05), and the children aged <1 year or ≥1 year in the non-encephalitis group had a significantly higher serum level of TLR3 than those in the encephalitis group (P<0.05). In the encephalitis group, the children aged ≥1 year had a significantly higher TLR3 concentration than those aged <1 year (P<0.05), and there were no significant differences in the TLR3 concentration between the children aged ≥1 year and <1 year in the non-encephalitis group and the control group. In the encephalitis group, the proportion of children aged <1 year was significantly higher than those aged ≥1 year (P<0.05).

CONCLUSIONSThe TLR3-1377C/T gene polymorphisms are not significantly associated with the development of EV71 encephalitis. Low expression of TLR3 might weaken the inhibitory effect on virus replication and promote the development of EV71 encephalitis. The deficiency in the expression of TLR3 in serum after EV71 infection might be an important factor for the development of encephalitis in infants.

OBJECTIVETo evaluate the efficacy and safety of the HAA regimen (homoharringtonine, cytarabine and aclarubicin) as induction chemotherapy in de novo acute myeloid leukemia (AML).

METHODSThe efficacy and safety of 236 de novo AML patients who received the HAA regimen as induction chemotherapy were retrospectively analyzed. The complete remission (CR) rate was assayed. Kaplan-Meier method was used to estimate overall survival (OS) and relapse free survival (RFS), and the differences were compared by Log-rank test.

RESULTSThe overall CR rate was 78.0%, and 65.7% of the patients attained CR in the first induction cycle. The early death rate was 4.7%. The median followup time was 41(1-161) months. The estimated 5-year OS and 5-year RFS rates were 44.9% and 45.5%, respectively. The CR rates of patients with favorable, intermediate and unfavorable cytogenetics were 92.9%,78.6%and 41.7%, respectively. The 5-year OS of favorable and intermediate group were 61.1% and 45.1%, respectively. The 5- year RFS of favorable and intermediate group were 49.0% and 45.4%, respectively. The median survival time of unfavorable group was only 5 months. The side effects associated with the HAA regimen were tolerable, in which the most common toxicities were myelosuppression and infection.

CONCLUSIONThe HAA regimen is associated with a higher rate of CR and longer survival time and its toxicity could be tolerated.

The aim of the present study was to investigate the effects of inositol 1,4,5-trisphosphate (IP(3))-generating agonist UTP on spontaneous transient outward currents (STOCs), and explore the role of intracellular Ca(2+) release in the current response mediated by IP(3) in porcine coronary artery smooth muscle cells (CASMCs). The coronary artery was excised from the fresh porcine heart and cut into small segments (2 mm × 5 mm) and then transferred to enzymatic dissociation solution for incubation. Single CASMCs were obtained by two-step enzyme digestion at 37 °C. STOCs were recorded and characterized using the perforated whole-cell patch-clamp configuration in freshly isolated porcine CASMCs. The currents were amplified and filtered by patch-clamp amplifier (Axopatch 200B), and then the digitized data were recorded by pClamp 9.0 software and further analyzed by MiniAnalysis 6.0 program. The results were as follows: (1) UTP led to conspicuous increases in STOC amplitude by (57.54±5.34)% and in frequency by (77.46±8.42)% (P<0.01, n=38). (2) The specific blocker of phospholipase C (PLC) - U73122 (5 μmol/L) remarkably reduced STOC amplitude by (31.04±7.46)% and frequency by (41.65±16.59)%, respectively (P<0.05, n=10). In the presence of U73122, UTP failed to reactivate STOCs (n=7). (3) Verapamil (20 μmol/L) and CdCl2 (200 μmol/L), two blockers of L-type voltage-dependent Ca(2+) channels, had little effects on STOCs initiated by UTP (n=8). (4) 1 μmol/L bisindolylmaleimide I (BisI), a potent blocker of protein kinase C (PKC), significantly increased STOC amplitude by (65.44±24.66)% and frequency by (61.35±21.47)% (P<0.01, n=12); UTP (40 μmol/L), applied in the presence of 1 μmol/L BisI, could further increase STOC activity (P<0.05, P<0.01, n=12). Subsequent application of ryanodine (50 μmol/L) abolished STOC activity. (5) In the presence of UTP (40 μmol/L), inhibition of IP(3) receptors (IP(3)Rs) by 2-aminoethoxydiphenyl borate (2-APB, 40 μmol/L) reduced STOC amplitude by (24.08±3.97)% (P<0.05, n=8), but had little effect on STOC frequency (n=8). While application of 2-APB (80 μmol/L) significantly reduced STOC amplitude by (31.43±6.34)% and frequency by (40.59±19.01)%, respectively (P<0.05, P<0.01, n=6). Subsequent application of ryanodine (50 μmol/L) completely blocked STOC activity. Pretreatment of cells with 2-APB (40 μmol/L) or ryanodine (50 μmol/L), UTP (40 μmol/L) failed to reactivate STOCs. The results suggest that UTP activates STOCs mainly via PLC and IP(3)-dependent mechanisms. Complex Ca(2+)-mobilization pathways are involved in UTP-mediated STOC activation in porcine CASMCs.

OBJECTIVETo explore a operative approach and its effect to the central protrusion of lumbar intervertebral disc.

METHODSFrom February 1999 to December 2005,34 patients with central protrusion of lumbar intervertebral disc were treated with an improved operative procedure. The study involved 25 males and 9 females with an average of 46.4 years (range, 35 to 63 years). The involved level of herniation were at L4,5 in 20 cases and L5S1 in 14 cases. Pains happened on one leg fixedly and seriously with another lightly in 21 cases, on one leg initially and lightly with another seriously later in 8 cases, on bilateral legs alike in 5 cases. Preoperative CT film showed central type in 8 cases and laterocentral type in 26 cases. The corresponding spinous process was resected on the basis of unilateral fenestration. The supraspinous ligament was retained and pulled to the opposite side for revealing spinal canal, and then diskectomy was done. The above procedure was named "fenestration with the spinous process resection".

RESULTSAll the 34 patients were followed up for 1 to 5 years. The outcome was evaluated according to the standard of HOU Shu-xun, 20 cases were excellent, 11 good and 3 fair. The total rate of excellent and good was 91.2%.

CONCLUSIONThe "fenestration with the spinous process resection" not only completed decompression of spinal canal and diskectomy, but also retained opposite lamina and supraspinous ligament and maintained the stability of posterior vertebral column, which are a new improved approach for the central protrusion of lumbar intervertebral disc.

Spontaneous transient outward currents (STOCs) play an important role in the myogenic regulation of small artery tone, such as coronary artery. In the present study, we investigated the electrophysiological properties and the regulation of STOCs in vascular smooth muscle cells (VSMCs) of porcine coronary artery by perforated patch-clamp technique. Our data showed that STOCs were dependent on voltage and extracellular calcium and they were highly variable in amplitudes and frequencies. STOCs superimposed stochastically onto whole-cell K(+) currents induced by step and ramp protocols. STOCs were completely abolished by ChTX [inhibitor of large-conductance Ca(2+)-activated potassium (BK(Ca)) channels], removal of extracellular Ca(2+), or addition of ryanodine (50 mumol/L) respectively. In contrast, CdCl2 and verapamil, inhibitors of voltage-dependent L-type Ca(2+) channels, had little effect on STOCs. Caffeine (5 mmol/L) transiently increased STOCs (hump), followed by a temporary inhibition. Ca(2+) ionophore A23187 increased both amplitude and frequency of STOCs. Na(+) ionophore monensin increased the frequency of STOCs. STOCs were strongly inhibited by KB-R7943, a selective inhibitor of the reverse mode of the Na(+)/Ca(2+) exchanger. Based on these observations, we conclude that STOCs are mediated by BK(Ca) channels. The generation and activation of STOCs depend upon Ca(2+) influx through Na(+)/Ca(2+) exchange and release of Ca(2+) from sarcoplasmic reticulum (SR) via ryanodine receptors. This suggests that Na(+)/Ca(2+) exchange determines calcium store refilling. Recycling of entering Ca(2+) from superficial SR may locally elevate Ca(2+) concentration at the plasma membrane, thereby activating BK(Ca) channels and then initiating STOCs.
