To detect chromosome translocation t(11;18) (q21;q21) and the nuclear expression of bcl-10 in gastrointestinal mucosa-associated lymphoid tissue (MALT) lymphoma in Chinese, a possible API2-MALT fusion transcript specific to t(11; 18) (q21; q21) in tumors from 42 cases of primary gastrointestinal lymphoma (29 cases of low grade MALT lymphoma, 13 cases of transformed MALT lymphoma) and 40 cases of diffuse large B cell lymphoma was examined by means of RT-PCR and proved by DNA-sequencing. Bcl-10 expression was examined by immunohistochemical method. The results showed that t(11;18) (q21;q21) was 14% positive in cases of low grade MALT lymphomas and 46% positive in transformed MALT lymphomas, but none in cases of DLBCL. Bcl-10 nuclear expression was seen 61% in low grade MALT and 69% in transformed MALT lymphoma. It was suggested that t(11;18) (q21;q21) was related to the prognosis and development of highly advanced MALT lymphoma but not relevant to DLBCL. Bcl-10 nuclear expressions were not significantly different between these two groups, which remains to be explained.

OBJECTIVETo study the pathological features of nasopharyngeal angiofibroma (NA) and the principles for clinical managements.

METHODSThirty-five patients with NAs were treated in First Affiliated Hospital of Fujian Medical University from Oct. 1981 to May 2007. The pathological changes, sites of origin, causes of intraoperative bleeding and the experiences of managements were retrospectively analysed. Using Fish stage: 6 cases were in stage I, 8 cases were in stage II, 17 cases were in stage III, 4 cases were stage IV. Two cases via endoscopic surgery, 2 cases via palatal approach, 19 cases via midfacial degloving approach, 9 cases via lateral rhinotomy approach, 3 cases via craniofacial combined approach.

RESULTSIn nasal cavity and paranasal sinus, the tumor was covered by squamous or columnar epithelium. The tumor extensions such as in pterygopalatine fossa and infratemporal fossa were covered by fibrous pseudocapsule. All cases of this series originated in the lateral wall of posterior portion of the nasal cavity. Fifteen of thirty-five cases confidentially originated near sphenopalatine foramen. Large and thick vessels in the pedicle region were the exact sites of serious intraoperative bleeding. Thirty-one cases were totally removed. Four cases were subtotal resected. Visual loss revealed in 6 cases, 4 cases visual acuity improved postoperatively. Three cases revealed postoperative dry eye due to surgical involvement of the sphenopalatine ganglion.

CONCLUSIONSnasopharyngeal angiofibroma is covered by epithelium or pseudo-capsule, it does not infiltrate the surrounding tissue. Dissecting along the surface of tumor might decrease bleeding and facilitate removal of tumor. An ideal surgical management should be done according to actually size and image examination, to the greatest extent keeping normal facial appearance. Attention should be paid to the complications such as visual loss and dry eye.

BACKGROUND: Spirituality has been an important part of Transpersonal Psychology and is believed to have a large effect on the mental health because it has been systematized. The aim of this study was to determine the level of spiritual disposition on human beings along with its effects on one's mental health. MATERIALS AND METHODS: The study targeted 400 women residing in Youn-Gil city of JiLin Prov., which is a district of the Cho-Sun tribe in China. Their spiritual well-being was studied using the Spiritual Well-being Scale-Korean Version. The spiritual well-being scale consists of 2 sub-scales of religious well-being and existential well-being. The study was evaluated using a lie scale, psychotic trend, and a combined anxiety-depression scale. The results were considered to be factors of one's mental health. The correlation between the spiritual well-being and each tendency was analyzed by regression analysis. RESULTS: The total score of the Cho-Sun tribal women according to the spiritual well-being scale was 68.29 which was much less than the 100.65 of Korean Christian women. There was no significant correlation between the spiritual well-being and the Lie trend. However, it was found that 86% (344) of Cho-Sun tribal women scored above 70 in the Lie trend with a mean score of 74.57 which is higher than normal populations. Regarding the correlation between the spiritual well-being and psychotic trend, the psychotic trend became significantly higher when the religious well-being was at a high level. On the other hand, the psychotic trend became significantly lower when the existential well-being was at a high level. Regarding the correlation between the spiritual well-being and anxiety, the anxiety was significantly higher when the religious well-being was at a high level. However, the anxiety level was significantly low when the existential well-being was at a high level. Regarding the correlation between the spiritual well-being and depression, the depression level was somewhat significantly high when the religious well-being was at a high level. However, the depression level was significantly low when the existential well-being was at a high level. CONCLUSION: This study evaluated the effects of spiritual well-being on a person's mental health among Cho-Sun tribal women in Youn-Gil city of JiLIn Prov., P.R. of China. The results found that the religious well-being, which is a sub-scale of spiritual well-being, had negative effects while the existential well-being had positive effects on the mental health. These results proved that a person's religious disposition had negative effects on their mental health in a communitarian society.

OBJECTIVEThrough systematic monitoring of the number and strain types of O1 and O139 Vibrio cholerae in the Pearl River estuary waters to analyze it's relevance with the temperature of environment, and the relevance between strains in water and isolates during outbreaks and epidemics as well as to estimate the methods used for environmental water detection and the potential role in cholera surveillance program.

METHODSTwenty-four stations along the Pearl River were selected and the water samples were collected monthly from March 2006 to February 2007. V. cholerae O1 and O139 strains were isolated from the samples. Real-time PCR established in our laboratory was used to detect V. cholerae O1 and O139. Air temperature and water temperature were collected during sampling. Pulsed field gel electrophoresis (PFGE) was applied in molecular typing of the isolates.

RESULTS862 water samples were collected during the study period. A total number of 77 O1 and O139 V. cholerae were isolated in 67 water samples and the positive rates were 7.77% for isolation and 26.33% for real-time PCR. Seasonal trend of positive rates by month were approximately coincident with the change of water temperature. The positive rates in the stations in urban area were higher than those in other areas. Toxigenic O139 strains were found in one station located in downstream of a marine market. Most of the O1 and O139 isolates were non-toxigenic. No trend of seasonal variation of the strains was noticed. Within these 75 isolates, 49 PFGE patterns were identified and the patterns differed widely with the similarity of 57.4% - 100%.

CONCLUSIONV. cholerae existed as the natural habitat in estuary water of the Pearl River and showed obvious genetic diversity. Data from monitoring waters might show the separation of strains with certain seasonal association. But the crowd did not show the relationship between the infections. Results from water surveillance program might provide indicators on the appearance of cholera pathogen which might be used in assessing the environmental risk of cholera epidemics as well as the alert of cholera.

Aim To explore the effects of Lycium berry seed oil on Nrf2/ARE pathway and oxidative damage in testis of subacute aging rats. Methods Fifty out of 60 male SD rats, aged 8 weeks, were subcutaneously injected with 125 mg • kg"D-galactosidase in the neck for 8 weeks to establish a subacute senescent rat model. The presence of senescent cells was observed using P-galactosidase ((3-gal), while testicular morphology was examined using HE staining. Serum levels of testosterone (testosterone, T), follicle-stimulating hormone ( follicle stimulating hormone, FSH ) , luteinizing hormone ( luteinizing hormone, LH ) , superoxide dis-mutase ( superoxide dismutase, SOD ) , glutathione ( glutathione, GSH) and malondialdehyde ( malondial-dehyde, MDA) were measured through ELISA, and the expressions of factors related to aging, oxidative damage, and the Nrf2/ARE pathway were assessed via immunohistochemical analysis and Western blotting. Results After successfully identifying the model, the morphology of the testis was improved and the intervention of Lycium seed oil led to a down-regulation in the expression of [3-gal and -yH2AX. The serum levels of SOD, GSH, T, and FSH increased while MDA and LH decreased (P 0. 05) . Additionally, there was an up-regulated expression of Nrf2, GCLC, NQOl, and SOD2 proteins in testicular tissue ( P 0. 05 ) and nuclear expression of Nrf2 in sertoli cells. Conclusion Lycium barbarum seed oil may reduce oxidative damage in testes of subacute senescent rats by activating the Nrf2/ARE signaling pathway.

Applying Chinese medicine (CM) is an important strategy for malignant tumor treatment in China. One of the significant characteristics of CM is to treat diseases based on syndrome differentiation. For Western medicine, it is of important clinical significance to formulate guidelines for the diagnosis and treatment of cancer patients based on the characteristics of disease differentiation. In Chinese clinical practice, the combination of disease differentiation and syndrome differentiation is an important feature for cancer treatment in the past. Currently, molecular profiling and genomic analysis-based precision medicine optimizes the anticancer drug design and holds the greatest success in treating cancer patients. Therefore, we want to know which populations of cancer patients can benefit more from CM treatment if the theory of precision medicine is applied to CM clinical practice. So, we developed a novel diagnostic and therapeutic strategy "disease-syndrome differentiation-genomic profiling-prescriptions" for cancer patients by CM syndrome differentiation and precision medicine. As a result, this strategy has greatly enhanced the anti-tumor efficacy of CM and improved clinical outcomes for cancer patients with some gene mutations. Our idea will hopefully establish a novel approach for the inheritance and innovation of CM.
