OBJECTIVETo investigate the effect of heme oxygenase-1 (HO-1) expression on cell growth and apoptosis in imatinib resistant chronic myeloid leukemia (CML) cells (K562/A02-IM), and explore the relationship between HO-1 gene and CML.

METHODSThe expression of HO-1 in 20 drug-resistant CML patients was detected by RT-PCR. Different concentrations of hemin were used to induce HO-1 expression of K562/A02-IM, HO-1 expression at different time was detected by RT-PCR and Western blot analysis. Cell apoptosis was detected by Annexin V/PI staining, and MTT assay was used to detect viability of K562/A02-IM cells after induction or inhibition of HO-1 gene by hemin and zinc protoporphyrin (ZPP).

RESULTSRT-PCR showed that HO-1 was expressed in the bone marrow mononuclear cells (BMMNCs). When treated with hemin at different concentrations (0, 10, 20, 40 µmol/L) for 16 h, the expression of HO-1 in K562/A02-IM was increased in a dose-dependent manner, and peaked at 20 µmol/L of hemin for 16 h. The apoptosis rates were (17.61 ± 0.01)%, (12.13 ± 0.11)%, (7.94 ± 0.03)% and (4.62 ± 0.15)% at 0,10, 20 and 40 µmol/L of hemin respectively for 16 h and were (14.7 ± 0.05)%, (8.1 ± 0.07)% and (16.3 ± 0.13)% at 20 µmol/L of hemin treatment for 8,16, and 24 h respectively. Hemin induced apoptosis of K562/A02-IM cells in a dose-dependent manner. The expression of HO-1 was induced in K562/A02-IM cells in a dose-dependent manner, and the survival of K562/A02-IM cells was significantly increased as compared to that of control group. When HO-1 was inhibited by ZPP, the cells survival was sharply decreased compared to that of the control group (P < 0.05).

CONCLUSIONHO-1 was expressed in the BMMNCs. It is a kind of molecules whose expression can be induced and can promote the growth of drug-resistant cells. Inhibition of HO-1 expression probably be used for the treatment of drug-resistant CML.

OBJECTIVE: To determine the efficacy of ultrasonogram in the detection of cornual pregnancy and the factors that might be affected on early diagnosis. METHOD: We studied 26 cases which were diagnosed as a cornual pregnancy from Jan, 1, 2000 to Dec, 31, 2004 at department of Obstetrics and Gynecology, St. Vincent's Hospital, the Catholic University of Korea. We compared two groups about clinical characteristics and outcomes. One group (A group) was diagnosed as cornual pregnancy before beginning of treatment, another group (B group) was not diagnosed as cornual pregnancy until operation. RESULTS: A group was 8 cases (30.8%) and B group was 18 cases (69.2%). There were no significant differences in age (33.0+/-6.21 years : 31.0+/-5.82 years), duration of amenorrhea (7.32+/-1.07 weeks : 8.90+/-5.44 weeks), previous cesarian section history (25.0% : 27.8%), present myoma (12.5% : 11.1%) and abdominal pain (50% : 77.78%), vaginal bleeding (50% : 55.6%), shock (0% : 27.8%) between two groups. There were significant differences in parity (1.63+/-0.74 : 1.0+/-0.77, p=0.032), number of abortions (2.25+/-1.16 : 1.11+/-1.18, p=0.016), previous history of ectopic pregnancy (37.5% : 0%, p=0.022). Of the method of treatments, only cornual resection (50% : 94.4%) showed significant differences between two groups. CONCLUSION: 30.8% of cornual pregnancy was early diagnosed by ultrasonogram. The important early detective factors for cornual pregnancy might be parity, previous ectopic pregnancy history and abortion history. Therefore if the patient has the previous ectopic pregnancy and abortion history, she can visit early to the hospital and the doctors do pay attention to the possibility of cornual pregnancy.

BACKGROUNDPrimary small cell carcinoma of the esophagus is rare. Although surgery is successful in eradicating local tumor, the five-year survival rate of patients with primary small cell carcinoma of the esophagus after resection is lower than that of patients with primary squamous cell carcinoma of the esophagus. The purpose of this study was to analyze the clinical manifestations, pathological features and treatment of primary small cell carcinoma of the esophagus.

METHODSA total of 73 patients with primary small cell carcinoma of the esophagus who had been treated by surgery from 1984 to 2003 were analyzed retrospectively.

RESULTSIn this series, the overall resection rate was 94.5% (69/73), the radical resection rate 89.0% (65/73) and the operative mortality 1.4% (1/73). The 1-, 3- and 5-year survival rates of patients were 50.7%, 13.7% and 8.2%, respectively.

CONCLUSIONSPrimary small cell carcinoma of the esophagus is rare with a poor prognosis. Surgical resection is the leading method for patients with stage I or II primary small cell carcinoma of the esophagus. Postoperative chemotherapy is beneficial to these patients. The patients of stage III or IV should be given chemotherapy and radiation therapy.

OBJECTIVETo evaluate the influence of Shenfu Injection (SHF) on the quality of life of patients with advanced non-small cell lung cancer (NSCLC) receiving chemotherapy.

METHODSA total of 133 patients with NSCLC receiving at least two cycles of chemotherapy with taxol plus cisplatin (TP)/vinorelbine plus cisplatin (NP) or gemcitabine plus cisplatin (GP) were randomized into SHF pre-treatment group (with SHF given only in the first cycle) and SHF post-treatment group (with SHF given only in the second cycle). The Quality of Life Questionnaire-Core 30 (QLQ-C30) and the Functional Living Index-Cancer (FLIC) were used to evaluate the quality of life of the patients after the treatments.

RESULTSBoth of the groups showed improved quality of life after the treatments (P<0.01), but the improvements were more obvious in SHF pre-treatment group (P<0.05). SHF showed favorable effects in relieving such adverse effects as fatigue, nausea, vomiting and diarrhea associated with the chemotherapy.

CONCLUSIONSHF can improve the quality of life in NSCLC patients receiving chemotherapies.

OBJECTIVETo investigate the lymph node metastasis and its risk factors in T1-2 staging invasive rectal carcinoma.

METHODSThe data of 1116 patients with rectal cancer treated with total mesorectal excision (TME) technique from January 2000 to April 2009 was analyzed retrospectively. The clinicopathological factors analyzed included gender, age, primary symptom type, number of symptoms, duration of symptom, synchronous polyps, preoperative serum carcino-embryonic antigen level, preoperative serum CA19-9 level, the distance of tumor from the anal verge, tumor size, tumor morphological type, tumor circumferential extent, tumor differentiation and tumor T staging. Statistical analysis was performed by using Logistic regression analysis and Chi-square test.

RESULTSA total of 1116 patients were enrolled, and 358 cases (32.1%) were classified as with T1-2 staging tumor. Two cases (5.6%, 2/36) in patients with a T1 staging tumor were found with lymph node metastasis, and 75 cases (23.3%, 75/322) in patients with a T2 staging tumor, respectively. Compared with patients with T3-4 staging tumor, lymph node metastasis rate of the patients with T1-2 staging tumor was significantly lower [21.5% (77/358) vs. 51.6% (391/758), P < 0.05]. Only the tumor T staging was found as the independent risk factor for the lymph node metastasis in patients with T1-2 staging tumor on multivariate Logistic regression analysis (odds ratio: 5.162; 95%CI: 1.212 to 21.991; P = 0.026).

CONCLUSIONSA substantial proportion of T1-2 staging rectal cancers harbor metastatic lymph nodes and the clinicopathological features except for T staging fail to predict the lymph node metastasis. Further research is warranted to identify the risk factors and guide the clinical practice in patient with T1-2 staging tumor.

Objective To assess the protective effect of the normobaric oxygen (NBO)and hyperbaric oxygen (HBO)on the acute ischemic stroke of rat using MR diffusion weighted imaging (DWI).Methods 30 adult male SD rats were subjected to right middle cerebral artery occlusion (MCAO)model using the suture method and transferred into a MRI scanner at 30 minutes after the onset of MCAO,then 30 rats were randomly divided into 3 groups (n=10 in each group),control,NBO and HBO group.NBO group rats were exposed to 100% oxygen for 2 hours,HBO group rats were administrated with hyperbaric oxygen for 2 hours respectively at 45 minutes after the onset of MCAO.Brain MRI scanner was performed at 12 h after the onset of MCAO,then pathological change of brain tissue was observed with hematoxylin-eosin (HE)staining and compared with DWI-infarct lesion.The relative cerebral infarction area and relative apparent diffusion coefficient (rADC)values of every group were measured on ADC maps.Results High signal intensity on MRI was found in the right cerebral ischemic region on DWI in three groups.The increased rates of the infraction lesion area in both NBO and HBO group were lower than that in control group (P<0.01),however,there was no significant difference between NBO and HBO group (P>0.05).The reduction rates of rADC in NBO and HBO group were significantly less than that in the control group (P<0.01),however,there was no significant difference between NBO and HBO group (P>0.05).HE staining confirmed that the cerebral infraction occured in three groups.There were significant positive correlations of the relative infarction lesion area between HE staining and DWI at 12 h after MCAO in three groups (P<0.01).Conclusion MRI shows that NBO and HBO could reduce the growth rates of cerebral infarction lesion area and the reduction rates of rADC,which proves that NBO and HBO have the neuroprotective effect on acute ischemic stroke of rats.

Objective To investigate the seroprevalence of tick-borne diseases in humans and domestic animals from rural areas of Zhejiang province. Methods Anji county, Jindong district and Tiantai county were selected for samples collection according to their geographic locations and historical prevalence of tick-borne diseases. Blood samples of humans and domestic animals were collected in the three sites. An indirect immuno-fluorescent antibody test was used to determine the presence of IgG antibodies of Rickettsiae heilongjiangii, Orientia tsutsugamushi, R. typhi, Anaplasma phagocytos, Ehrlichia chaffeensis, Bartonella, R. hainan and Coxiella burnetii in these samples.Results Six hundred and eighty-three blood samples including 579 from humans and 104 from domestic animals(53 from cattles and 51 from sheep)were collected from the three sites. Antibody positive rates of Orientia tsutsugamushi, R. typhi, Ehrlichia chaffeensis and Coxiella burnetii were significantly different between these sites. IgG from all the 8 pathogens were detected in samples from humans. It was found that the sero-prevalence rates of R. typhi, Bartonella and C. burnetii(20.7%,10.9%, 5.5%)of adults were higher than those of other Rickettsiae under investigation. The seroprevalence of R. typhi increased along with age. IgG from the 7 pathogens were detected in samples from domestic animals except for Anaplasma phagocytos. The sero-prevalence rates of R. typhi, Bartonella and R. hainan(69.2%, 51.0%, 22.1%)of adults were higher than those of other Rickettsiae investigated. Conclusion Tick-borne diseases did spread widely in humans and domestic animals from different rural areas of Zhejiang province. The sero-prevalence rates of R. typhi,B. henselae, R. hainan and C. burnetii were higher than that from other pathogens.
