Objective To explore the influence and treatment methods of hysteromyoma pregnancy. Method Through case-control study on 116 cases of hysteromyoma pregnancy and the same number cases of normal pregnan-cy in the same period, in order to observe the outcome of two groups. Results There is no significant difference in the matter of amount of bleeding when hysteromyoma pregnant women give birth to their children, no matter how oper-ation group, non-surgical group and control group(P > 0.05); but there is significant difference between non-surgical group and control group(P <0.05), and in the field of asphyxia neonatorum rate, there is no significant difference in all groups(P > 0.05). Conclusions The amount of bleeding in hysteromyoma pregnant women are more than vagi-nal delivery non-hysteromyoma women. It suggests that myomectomy won' t increase the amount of bleeding when doctors give the hysteromyoma women caesarean section at the same time. And the difficulty of surgery won' t signifi-cantly increase when compared to non-pregnancy and pregnancy.

Objectiv e Renal ischemia-reperfusion ( I/R) may cause myocardial injury and dexmedetomidine ( DEX) is a new alpha-2 adrenergic agonist with the effects of antisympathia , seda-tion, and analgesia.This study was to investigate the effect of DEX on the myocardial tissue of rats at different time points after renal I/R. Methods Forty male Wistar rats were randomized into 5 groups of equal number,sham operation, 60 min renal ischemia and 3 h reperfusion (I/R1), 120 min ischemia and 3 h reperfusion (I/R2 ), 60 min ischemia and DEX+3 h reperfusion (D1), 120 min ischemia and DEX+3 h reperfusion ( D2) .Renal I/R was induced by removal of the right kidney and ligation of the left re-nal artery and vein followed by 3 hours of reperfusion.Meanwhile, intraperitoneal injection of DEX at 50μg/kg was given to the ani-mals in groups D1 and D2 at 60 at 120 min respectively after ischemia.After 3 hours of reperfusion, blood samples were collected for measurement of the concentrations of serum creatinine (Cr) and blood urea nitrogen (BUN), and renal and myocardial tissues harvested for observation of pathological changes under the light microscope and determination of the expressions of TNF-αand IL-10 by ELISA.Results Significant increases were observed in the concentrations of serum Cr and BUN , the expressions of TNF-αand IL-10 in the renal tissues and those in the myocardial tissues in groups I /R1([84.67 ±9.62] μmol/L, [8.55 ±1.08] mmol /L), I/R2 ([167.11 ±18.81] μmol/L, [13.42 ±1.25] mmol/L), D1 ([69.67 ±9.52] μmol/L, [7.56 ±0.70] mmol/L), and D2 ([114.29 ±12.50] μmol/L, [10.27 ±0.78] mmol/L), as compared with the sham operation group ([53.20 ±9.21] μmol/L, [3.75 ±0.78] mmol/L), (all P <0.05).Significant decreases was observed in the sham operation group as compared with other groups in the expressions of TNF-αand IL-10 (P<0.05).Significant decreases was observed in the D1 and D2 groups compared with other groups in the expressions of TNF-α, but increasing in IL-10.②Injury was reduced in the D1 and D2 groups compared with other groups.③The horizontal stripes of myocardial tissue disappeared in I/R1 and I/R2 decreases of inflammatory cells was observed in D1 and D2 groups compared with others. Conclusion Dexmedetomidine can attenuate myocar-dial injury induced by renal ischemia-reperfusion in rats and its inhibitory effect on inflammatory factors may be involved in the mechanism.

OBJECTIVETo study the expression of human beta-defensin-3 (hBD-3) induced by lipopolysaccharide (LPS) in human bronchial epithelial (HBE) cells, and explore the role of hBD-3 in respiratory infection.
METHODSHBE cells were stimulated with different concentrations of LPS (0.01, 0.1, 1 and 10 microg/mL). hBD-3 mRNA expression was detected by RT-PCR 2 hrs later. hBD-3 protein expression was detected by Western blot 4 hrs later.
RESULTShBD-3 mRNA and protein was weakly expressed in normal HBE cells. LPS stimulation resulted in a significant increase of hBD-3 mRNA and protein expression (p<0.01). hBD-3 mRNA and protein expression increased with increasing LPS concentrations. There were significant differences in the hBD-3 mRNA and protein expression in cells stimulated by different concentrations of LPS (p<0.05).
CONCLUSIONSLPS can induce hBD-3 expression in a dose-dependent manner. hBD-3 might play a role in initial defensive reaction against bacterial invasion.

OBJECTIVETo explore the values of adrenocorticotropic hormone receptor (ACTH-R) determination and ultrastructural observation of tumor cells in the subtyping of adrenocortical neoplasms (ANs).
METHODSThe expression of ACTH-R in 87 AN tissues were determined with Polymer immunohistochemical staining, with 10 normal adrenal tissues as the controls. The ultrastructure of the tumor cells was observed using electron microscopy.
RESULTSThe positive expression rate of ACTH-R was (80.1 +/- 8.2)%, (53.2 +/- 10.3)%, (63.2 +/- 10.1)%, (83.3 +/- 6.5)%, and (70.1 +/- 7.3)% in the sub-CPA group, CPA group, APA group, NFA group, and NC group, respectively. ACTH-R expression was significantly higher in NFA and sub-CPA groups than in NC group (P = 0.001, P = 0.000), APA group (P = 0.000, P = 0.000), and CPA group (P = 0.000, P = 0.000), and was also significantly different between NC group and APA group (P = 0.039) and between APA group and CPA group (P = 0.037). However, no significant difference was found between NFA group and sub-CPA group (P = 0.325). As shown by the electron microscopy, ANs had some partially similar microscopic features, while different AN subtypes showed differences in the type and amount of secretory granules.
CONCLUSIONACTH-R determination and ultrastructural observation of tumor cells may be helpful for subtyping ANs.
