OBJECTIVE:
In order to investigate the interaction between the cytokines and keratinocyte and determine the role of cytokines in hyperproliferative of chronic otitis media with cholesteatoma, we observe the expression of matrix metalloproteinase 9 (MMP9), vascular endothelial growth factor (VEGF), keratinocyte growth factor (KGF) and its receptor (KGFR) in middle ear cholesteatoma.
METHOD:
We examined the expression of MMP9, VEGF, KGF, KGFR and Ki-67 by immunohistochemistry in 50 specimens from chronic otitis media with cholesteatoma and 15 specimens from the normal skin of external auditory meatus. Ki-67 as an evaluation of cholesteatoma proliferation markers were used to detect the keratinocyte proliferative activity.
RESULT:
(1) The expression of VEGF and MMP9 in cholesteatoma specimens was higher than normal skin, and the difference was statistically significant (t = 4.914, P < 0.01; t = 3.284, P < 0.01). (2) The expression of KGF and KGFR in middle ear tissues was higher than normal skin, and the difference was statistically significant (t = 4.814, P < 0.01; t = 3.104, P < 0.01); The expression of KGF and KGFR increased, and the expression of Ki-67 also correspondly increased in the cholesteatoma. (3) In the tissue MMP9 and VEGF were positive. Mean optical density increased as well. KGF expression also increased accordingly.
CONCLUSION
MMP9, VEGF, KGF and KGFR proteins played an important role in hyperproliferation of cholesteatoma tissues. VEGF, MMP9 and KGF had a synergistic effect in hyperproliferation of cholesteatoma tissues.

Background and purpose:Herpes zoster is a common adverse event associated with the use of bortezomib. The objective of this study was to evaluate the efifcacy of different therapeutic regimens of valacyclovir prophylaxis: continuously administration and intermittent administration. Methods: We retrospectively analyzed the efficacy, side effects, expense of valacyclovir and emotional states of 31 patients with multiple myeloma who received bortezomib and valacyclovir prophylaxis. Among them, 14 patients underwent continuously administration of valacyclovir, the other 17 patients underwent intermittent administration. Continuously administration was deifned as daily oral valacyclovir 600 mg without cessation during entire period of bortezomib treatment. Intermittent administration was deifned as patients received valacyclovir at a dose of 600 mg daily during chemotherapy, while discontinue valacyclovir at the intermission time of bortezomib treatment. Results: There were no herpes zoster in patients of 2 arms. Adverse events over grade 3 associated with valacyclovir were not observed. Intermittent administration of valacyclovir showed a superiority of economic beneift. The emotional status were depended on the therapeutic effects of multiple myeloma. For those relapsed or refractory patients, continuously administration of valacyclovir might aggravate depression and anxiety. Conclusion:Intermittent administration of valacyclovir at a dose of 600 mg daily appears to be an effective prophylaxis for herpes zoster in patients receiving bortezomib.

Objective To determine the persistence time of genotype 4 hepatitis E (HE) viremia after the onset of clinical symptoms in HE patients and provide essential data for study on HE epidemiologieal transmission, so that to evaluate potential contagiousness of HE patients after clinical stage. Methods The first serum samples from 162 HE patients after hospitalized in Eastern China were collected and tested for hepatitis E virus (HEV) RNA by nested reversed transcription- polymerase chain reaction (RT-PCR). The persistence time of HEV viremia after the onset of clinical symptoms was estimated with Kaplan-Meier survival analysis. Results HEV RNA was detectable in 101 out of 162 serum samples with positive rate of 62.35%, which was all grouped to genotype 4 by homology analysis. Furthermore, HEV RNA was detectable in 74 (64.91%) out of 114 male and 27 (56.25%) out of 48 female, which was not significantly different (χ2 = 1.08, P=0. 30). Kaplan-Meier survival analysis showed that the median persistence time of HEV genotype 4 viremia was 24 days after the onset of clinical symptoms (95% CI: 18-30 days), which meant that the viremia of 50% HE patients remaining detectable up to 24 days after the onset. The 75% and 25% percentiles were 14 days and 31 days, respectively. There was no significant difference of viremia persistence time between male and female (Breslow test: P=0.98, Tarone-Ware test: P=0.91). Conclusions The viremia of 75% patients with HEV genotype 4 infection could persistent until 2 weeks after the onset of clinical symptoms and that of some patients could persistent over 1 month. It is indicated that the viremia is still persistent and HE patient could be a reservoir even after the clinical symptoms disappeared and biochemical marks normalized.

Objective To investigate the effect of carbachol on local gut inflammation during entetal resuscitation of rats with bum shock. Method Thirty-eight Wistar rats were subjected to 35%TBSA full thickness scald injury, and enteral fluid was infused into animal intestines via duodenal stomas 30 minutes post bum. The animals were randomly divided into four groups: no resuscitation (Control, n = 8), enteral resuscitation using either a glucose electrolyte solution (GES, n = 10) or GES plus carbachol (60 μg·kg-1,GES/CAR, n = 10), or carbachol alone (CAR, n = 10) .The volumeof GES infusion was based on the Parkland formula (4 ml· 1% TB-SA-1·Kg-1) - All animals were sacrificed 4 hours post bum, and specimens of jejunal tissue were collected to determine the levels of tumor necrosis factor (TNF)-α, nitric oxide (NO), nitric oxide synthase (NOS) and myeloperoxidase (MPO). Serum assays for plasma diamine oxidase (DAO) activities were also performed. Results There were no statistical differences in the intestinal levels of NOS, NO, TNF-α and MPO, and plasma OAO activities, between the GES group and the control group. Compared to the GES group, the GES/CAR group showed significantly lowered levels of intestinal NOS (1.276 ±0.391 vs. 1.818 ±0.436, P<0.05), NO (0.925 ±0.402 vs. 1.561 ±0.190, P < 0.05, TNF-α (0.87±0.13 vs. 1.94±0.47, P <0.01) and MPO (0.465 ±0.092 vs. 0.832±0.214, P<0.05),and reduction in plasma DAO activites (0.732±0.192 vs. 1.381 ±0.564, P <0.05). The CAR group also showed significantly lowered levels of intestinal NOS, NO, TNF-α and MPO and reduced plasma DAO activites, compared to the GES group. Conclusions Theses results suggest that carbachol significantly inhibits the release of proinflammatory mediator and attenuates local inflammation in gut during enteral fluid resuscitation of rats in rats with bum shock. We postulate that carbachol may exert its and-inflammatory effects via the cholinergic anti-inflammatory pathway.
