OBJETIVO: avaliar se a Lei Seca cumpriu sua meta após três anos da promulgação. MÉTODOS: estudo retrospectivo dos pacientes com fraturas craniofaciais submetidos a tratamento cirúrgico em um hospital universitário, em dois períodos: antes (2005 a 2008) e após a implantação da lei (2008 a 2011). RESULTADOS:foram operados 265 pacientes (220 homens e 45 mulheres) nesse período sendo, 149 (56%) antes da lei e 116 (44%) após a lei, indicando redução no número de traumatismos (p=0,04). Houve predomínio da faixa etária entre 19 e 40 anos, em ambos os períodos. As principais causas dos traumas foram os acidentes automobilísticos, as agressões físicas e as quedas. O abuso de álcool foi identificado em 15,4% dos pacientes antes e 19% após a lei. A mandíbula e o complexo maxilozigomático foram os ossos mais acometidos. CONCLUSÃO:a redução no número de politraumatizados operados ficou aquém do esperado e almejado.

Objetivo: avaliar a eficácia da ablação histeroscópica do endométrio no tratamento cirúrgico da menorragia. Métodos: foram realizadas 200 ablações histeroscópicas do endométrio no período de abril de 1991 a abril de 1999 em pacientes de clínica privada dos autores. Todas as pacientes apresentavam sangramento uterino anormal de causa benigna rebelde ao tratamento clínico. O procedimento foi realizado em ambiente hospitalar sob anestesia de bloqueio (raqui ou peridural). Nos primeiros quatro anos utilizou-se a glicina 1,5% como meio de distensão da cavidade uterina e nos últimos quatro anos o manitol 3%. O seguimento variou de 8 meses a 8 anos. Resultados: das 200 pacientes, 180 (90%) mostraram-se satisfeitas com o procedimento, relatando diminuição acentuada do fluxo menstrual. A análise histológica do endométrio após ressecção histeroscópica revelou atividade proliferativa em 104 pacientes (52%), e secretora em 34 (17%). A hiperplasia endometrial esteve presente em 20 pacientes (10%). As pacientes que se submeteram à ressecção apresentaram a cavidade uterina diminuída e formação de sinéquias fibrosas, ao passo que nas pacientes que foram submetidas à destruição endometrial a cavidade mostrou-se diminuída porém sem formação de sinéquias. Duas pacientes apresentaram quadro de hipervolemia moderada durante o procedimento, que respondeu bem ao tratamento clínico. Ocorreu um episódio de perfuração uterina durante a fase de dilatação e cinco casos de hematômetra foram registrados. Conclusões: A ablação histeroscópica do endométrio é um procedimento seguro e eficaz em pacientes selecionadas no tratamento da menorragia de causa benigna rebelde a tratamento clínico.

PURPOSE: To verify the predictors of intravasation rate during hysteroscopy.METHODS: Prospective observational study (Canadian Task Force classification II-1). All cases (n=200 women; 22 to 86 years old) were treated in an operating room setting. Considering respective bag overfill to calculate water balance, we tested two multiple linear regression models: one for total intravasation (mL) and the other for absorption rate (mL.min-1). The predictors tested (independent variables) were energy (mono/bipolar), tube patency (with/without tubal ligation), hysterometry (cm), age≤50 years, body surface area (m2), surgical complexity (with/without myomectomy) and duration (min).RESULTS: Mean intravasation was significantly higher when myomectomy was performed (442±616 versus 223±332 mL; p<0.01). In the proposed multiple linear regression models for total intravasation (adjusted R2=0.44; p<0.01), the only significant predictors were myomectomy and duration (p<0.01).In the proposed model for intravasation rate (R2=0.39; p<0.01), only myomectomy and hysterometry were significant predictors (p=0.02 and p<0.01, respectively).CONCLUSIONS: Not only myomectomy but also hysterometry were significant predictors of intravasation rate during operative hysteroscopy.

YKL-40 has been identified as a growth factor in connective tissue cells and also a migration factor in vascular smooth muscle cells. To a large extent, the increase of serum YKL-40 is attributed to liver fibrosis and asthma. However, the relationship of the expression and clinical/prognostic significance of YKL-40 to the splenomegaly of patients with portal hypertension is unclear. In the present study, the expression of YKL-40 was studied by immunohistochemistry in 48 splenomegaly tissue samples from patients with portal hypertension and in 14 normal spleen specimens. All specimens were quickly stored at -80°C after resection. Primary antibodies YKL-40 (1:150 dilution, rabbit polyclonal IgG) and MMP-9 (1:200 dilution, rabbit monoclonal IgG) and antirabbit immunoglobulins (HRP K4010) were used in this study. The relationship of clinicopathologic features with YKL-40 is presented. The expression of YKL-40 indicated by increased immunochemical reactivity was significantly up-regulated in splenomegaly tissues compared to normal spleen tissues. Overexpression of YKL-40 was found in 68.8% of splenomegaly tissues and was significantly associated with Child-Pugh classification (P = 0.000), free portal pressure (correlation coefficient = 0.499, P < 0.01) and spleen fibrosis (correlation coefficient = 0.857, P < 0.01). Further study showed a significant correlation between YKL-40 and MMP-9 (correlation coefficient = -0.839, P < 0.01), indicating that YKL-40 might be an accelerator of spleen tissue remodeling by inhibiting the expression of MMP-9. In conclusion, YKL-40 is an important factor involved in the remodeling of spleen tissue of portal hypertension patients and can be used as a therapeutic target for splenomegaly.

Rhein is a primary anthraquinone found in the roots of a traditional Chinese herb, rhubarb, and has been shown to have some anticancer effects. The aim of the present study was to investigate the effect of rhein on the apoptosis of the human gastric cancer line SGC-7901 and to identify the mechanism involved. SGC-7901 cells were cultured and treated with rhein (0, 50, 100, 150, and 200 µM) for 24, 48, or 72 h. Relative cell viability assessed by the MTT assay after treatment was 100, 99, 85, 79, 63% for 24 h; 100, 98, 80, 51, 37% for 48 h, and 100, 97, 60, 36, 15% for 72 h, respectively. Cell apoptosis was detected with TUNEL staining and quantified with flow cytometry using annexin FITC-PI staining at 48 h after 100, 200 and 300 µm rhein. The percentage of apoptotic cells was 7.3, 21.9, 43.5%, respectively. We also measured the mRNA levels of caspase-3 and -9 using real-time PCR. Treatment with 100 µM rhein for 48 h significantly increased mRNA expression of caspase-3 and -9. The levels of apoptosis-related proteins including Bcl-2, Bax, Bcl-xL, and pro-caspase-3 were evaluated in rhein-treated cells. Rhein increased the Bax:Bcl-2 ratio but decreased the protein levels of Bcl-xL and pro-caspase-3. Moreover, rhein significantly increased the expression of cytochrome c and apoptotic protease activating factor 1, two critical components involved in mitochondrial pathway-mediated apoptosis. We conclude that rhein inhibits SGC-7901 proliferation by inducing apoptosis and this antitumor effect of rhein is mediated in part by an intrinsic mitochondrial pathway.
