OBJECTIVE:To study the effects of indometacin on apootosis and proliferation of cervical cancer Hela cell. METH-ODS:Hela cell was cultured in vitro as study object,and cultured with 0(blank control),200,400,600,800 and 1 000 μmol/L indometacin for 24,48 and 72 h. The inhibitory rate of indometacin to the proliferation of Hela cells was detected by MTT assay. After treated with 0(blank control),400,600 and 800 μmol/L indometacin for 24 h,the change of cellular morphology was ob-served by invert microscope;cell cycle phase and apoptosis were analyzed by flow cytometry. RESUITS:Indometacin of 600, 800,1 000μmol/L could inhibit the proliferation of Hela cell,which was positively correlated to drug concentration and time. Com-pared with blank control,indometacin could induce that Hela cell transformed from polygonous to round in appearance,and result-ed in cell apoptosis and necrosis;the proportion of cells at G0/G1 phase increased,while the proportion of cells at S phase reduced;the apoptotic rate of cells raised. CONCLUSIONS:Indometacin could inhibit the proliferation of Hela cell,block cell cycle at G0/G1 phase and induce apoptosis.

Objective To determine the mechanism of nitric oxide synthase(NOS) and prostacyclin(PGI2) acting on splanchnic hyperdynamic circulation of portal hypertention(PHT). Methods Ninety-six Sprague-Dawley rats were divided into three groups, namely, intrahepatic portal hypertension(IHPH, n=31), prehepatic portal hypertension(PHPH, n=33) and sham-operated controls(SO, n=32). Animals of each group were received indomethacin(INDO) either on a short term or long term with saline as control. Portal venous pressure, together with the concentration of nitric oxide (NO) and PGI2 in serum was measured. The constitutive nitric oxide synthase(cNOS)and inducible nitric oxide synthase(iNOS)activity in the abdominal aorta and small intestine of these rats were detrmined by spectrophotometry method. RT-PCR was performed to measure the levels of iNOS and cNOS mRNA in the arteries and guts mentioned above. Results Although INDO decreased the concentration of PGI2 in serum, the long-term INDO-treated group restored splanchnic hyperdynamic circulation in both IHPH and PHPH rats, concomitant with enhanced expression of iNOS and concentration of NO(P0.05). Conclusion Overproduction of NO inducing hemodynamic abnormalities of PHT is synthesized principally by increase of iNOS. There may be a possible interaction between PGI2 and NO in hyperhemodynamics of PHT, while PGI2 may not be a mediator in the formation and development of hyperdynamic circulatory state.

Objective To explore the values of manual anastomosis with two operations out of anus in laparoscopic anal sphincter preserving resection of ultra low rectal cancer. Methods Radical excision of ultra low rectal cancer was performed with ultrasonic scalpel in 12 patients based on the concept of total mesorectal excision (TME) and ultra low coloreclal/anal anastomosis was performed applying manual anastomosis with two operations out of anus. Results All the operations were finished successfully, without conversions to open for surgery. One case had anastomotic leakage, and there were no bleeding and infection of abdominal cavity, anastomotic stenosis and other complications. The operating time was 185-310 (218 ±10) min, the blood loss was 160-450 (232 ±8) ml,the length of hospital stay was 9-14 (11 ±3) d. All patients were followed up 6-36(18 ± 2) months, local recurrence was not found but 1 case had liver metastasis.Conclusions The manual anastomosis with two operations out of anus in laparoscopic anal sphincter preserving resection of ultra low rectal cancer is safe,economical,effective,minimally invasive, and has the benefits of less bleeding during the operation and shorter hospital stay. It should be widely used.

Objective To investigate the expression levels and the roles of IL-17 and IL-23 in children with Mycoplasma pneumoniae (MP) pneumonia. Methods One hundred and three children with pneumonia admitted to pediatric department from February to May in 2012 were divided into MP pneumonia group and non-MP pneumonia group according to the results of MP antibody tests. Meanwhile, 42 healthy children were chosen as normal controls. Serum levels of IL-17, IL-23 and MP antibodies were measured in all children. Immunoglobulin, C reactive protein, total white blood cell count and granulocyte count were detected in children with pneumonia. Results The serum levels of IL-17 and IL-23 were signiifcantly different among three groups (P<0.05). The children in MP pneumonia group had higher levels of IL-17 and IL-23 than those in non-MP pneumonia group (P<0.05). Compared with the control group, levels of IL-17 and IL-23 were higher in two pneumonia groups (P<0.05). There was no signiifcant difference in levels of IL-17 and IL-23 between pneumonia patients with normal and with abnormal levels of immunoglobulin (P>0.05), while IL-17 and IL-23 levels were both positively correlated with granulocyte count (P<0.05).Conclusion IL-17 and IL-23 may be involved in the immune response of MP pneumonia and may contribute to the clearance of pathogens.
