UNLABELLEDTo investigate the clinical and pathological characteristics, treatment, and The data of 12 patients prognosis of synchronous primary cancer of the endometrium and ovary. Methods with synchronous primary cancer of the endometrium and ovary were retrospectively reviewed . Results Eight patients had the same histological type of endometrioid carcinoma in both uterus and ovary, 4 patients had different histological types in uterus and ovary. Synchronous primary cancer of the endometrium and ovary was difficult to be dignosed preoperatively. All ovarian tumors were small with an average diameter of 7 cm. Infertility was common among these patients(40.7%). Most of them had early stage I lesion (66.7%). endometrioid carcinomas was the main pathologic type (66.7%). All patients were treated surgically followed by chemotherapy with a 3-year survival rate of 66.7% (8/12).
CONCLUSIONSynchronous primary endometrium and ovary cancer is a specific kind of tumor different from either the primary endometrium carcinoma or ovary carcinoma, and usually can be detected in early stage with a good prognosis.

Objective To investigate the effect of chlorhexidine gluconate in prevention of surgical site infection ( SSI ) . Methods Randomized controlled clinical trial method was used in the study. Comparison was made in the rates of SSI between the experiment group using 2% chlorhexidine gluconate and the control group. Results The rate of SSI in experiment group was significantly lower than that in control group (0.83% vs.5.83%, χ2 =3.23,P =0.035).Differences of hospital stay, total cost, infection in other sites and mortality rate of SSI were not statistically significant between the two groups ( P>0 .05 ) . Conclusion Preoperative head disinfection by chlorhexidine gluconate has remarkable effect in prevention of cerebral surgical site infection.

BACKGROUNDSolamargine (SM), a steroidal glycoalkaloid isolated from the Chinese herb Solanum incanum, has been shown to inhibit the growth of some cancer cell lines and induce significant apoptosis. However, the effects of SM on multidrug-resistant (MDR) cells and the molecular mechanisms involved are poorly understood. The purpose of this study was to evaluate the anti-MDR effects of SM and the associated mechanisms in MDR K562/A02 cells.
METHODSThe cytotoxicity of SM was measured by 3-(4,5-dimethylthiazol)-2,5-diphenyltetrazolium bromide (MTT) assay. The 14',6-diamidino-2-phenylindole (DAPI) nuclear staining and flow cytometry were used to detect SM-induced apoptosis. The mRNA expression of P-glycoprotein (P-gp) was investigated by real-time PCR (RT-PCR). Western blotting was used to determine the expression of Bcl-2, Bax, and actin. The changes in the morphology of actin were examined with immunofluorescence staining.
RESULTSMTT results showed that SM effectively killed the MDR sublines K562/A02, KB/VCR, and H460/paclitaxel (Taxol), and their parental cell lines K562, KB, and H460 to an equivalent or more sensitive degree. Based on the results by flow cytometry and immunostaining, the pro-apoptotic effects of SM were observed in MDR K562/A02 cells. Furthermore, the RT-PCR results showed that SM induced the downregulation of MDR1 mRNA. In addition, the expression of P-gp and actin was decreased in the SM-treated cells, as measured by western blotting and immunostaining.
CONCLUSIONSThese results demonstrate that SM effectively triggers apoptosis in MDR tumor cells, which is associated with actin disruption and downregulation of MDR1 expression. This compound may merit further investigation as a potential therapeutic agent that bypasses the MDR mechanism for the treatment of MDR tumors.

OBJECTIVETo retrospectively study the clinical effects of eardrum flap area on the healing outcome following traumatic perforation.
METHODSTotally 291 traumatic eardrum perforations with in-/everted edges were included in this study. They were randomly divided into three groups and received conservative treatment, epidermal growth factor (EGF) via Gelfoam patching, or edge-approximation plus Gelfoam patching respectively. Patients in each group were further divided into two subgroups according to the eardrum flap area less than or equal to 1/2 or >1/2 of the perforation size. The healing rate and mean closure time after tympanic membrane perforation were evaluated at three months.
RESULTSOf the total 291 participants, 281 were included in the final statistical analysis. The area of curled edge did not affect the healing outcome significantly in any groups (P>0.05). The healing rate varied slightly: 90.7% vs 92.3% in spontaneous healing group, 98.2% vs 97.4% in EGF via Gelfoam patching group, and 96.5% vs 100% in edge-approximation plus Gelfoam patching group. In addition, in all groups the area of curled edge did not affect the mean closure time significantly (P>0.05). The closure time was (32.3+/-2.4) d vs (30.6+/-3.1) d in sponaneous healing group, (13.4+/-2.5) d vs (13.1+/-1.9) d in EGF via Gelfoam patching group, and (11.9+/-3.1) d vs (12.2+/-2.1) d in edge-approximation plus Gelfoam patching group.
CONCLUSIONThe eardrum flap area of traumatic eardrum perforation does not significantly affect the clinical outcomes.

OBJECTIVETo study the effect of Xinnao Shutong capsule (XNST) on energy metabolism dysfunction, free radical injury and inflammatic factors in the course of acute cerebral ischemic damage, and try to reveal the mechanism of the protection against ischemia.
METHOD60 male Wistar rats weighing 280 - 320 g were randomly divided into five groups: normal, sham operation, model, XNST treatment( XNST-T) , and Western medicine treatment (WM-T) group. Acute multi-infarct model in rats was induced by injecting the embolus of blood powder through the right external carotid artery (ECA) into the internal carotid artery (ICA). At 72 hours after ischemia, morphologic change and the express of tumor necrosis factor-alpha (TNF-alpha) and interleukin -1beta ( IL-1beta) in hippocampus CAl section and cortex were observed, biochemical criterions including the activity of Na+ -K+ -ATPase, lactate dehydrogenase (LDH), superoxide dismutase (SOD), and the content of malondialdehyde (MDA) in hippocampus were examined.
RESULTThe morphologic change of hippocampus and cortex in both XNST-T and WM-T groups was milder than that in model group. The activity of Na+ -K+ -ATPase, LDH and SOD in hippocampus were all significantly decreased in model group (P <0. 01), and elevated in XNST group (P <0. 01) as well as in WM-T group (P <0. 01). The content of MDA in hippocampus was significantly increased in model group (P <0. 05), and was reduced in XNST group (P <0. 05) as well as in WM-T group (P <0. 01).
CONCLUSIONThe results reveal that XNST has the protective effect against cerebral ischemic injury. And its possible mechanism is that XNST can prevent the upper pathological process.

OBJECTIVETo study genetic damage of workers alone occupationally exposed to methotrexate (MTX) with three end-points.
METHODSThe blood samples from 21 workers exposed to MTX and 21 controls were detected with micronucleus test, comet assay, hprt gene mutation test and TCR gene mutation test.
RESULTSThe mean micronuclei rate (MNR) and mean micronucleated cells rate (MCR) in 21 workers were 10.10 per thousand +/- 0.95 per thousand and 8.05 per thousand +/- 0.75 per thousand, respectively, which were significantly higher than those (5.48 per thousand +/- 0.82 per thousand and 4.38 per thousand +/- 0.58 per thousand) in control (P < 0.01). The mean tail length (MTL) of 21 workers and 21 controls were (1.30 +/- 0.06) microm and (0.07 +/- 0.01) microm, respectively, there was significant difference between workers and controls (P < 0.01). But the difference between workers and controls for mean tail moment (MTM) was not significant (P > 0.05). The average mutation frequency (Mf-hprt) of hprt and (Mf-TCR) of TCR in workers were 1.00 per thousand +/- 0.02 per thousand and (6.87 +/- 0.52) x 10(-4), respectively, which were significantly higher than those [0.86 per thousand +/- 0.01 per thousand and (1.67 +/- 0.14) x 10(-4)] in control (P < 0.01).
CONCLUSIONThe genetic damage to some extent appeared in workers occupationally exposed to methotrexate.
