Objective: To understand the status, attitude and related risk factors on smoking among 18-65 years old patients with hypertension, diabetes, dyslipidemia, chronic obstructive pulmonary disease (COPD) or asthma in Beijing. Methods: Data was gathered from the 2014 Beijing Non-communicable and Chronic Disease Surveillance Program. Multiple classified cluster sampling method was used and 19 815 participants aged 18-65 were sampled from 16 districts in Beijing. Results: Among all the 18 405 participants, male hypertensive patients showed a higher rate on current smoking than the other groups (χ(2)=17.695, P<0.001). Male patients with dyslipidemia had higher current smoking rate than the other groups (χ(2)=39.292, P<0.001). However, female patients with COPD or with asthma showed higher rate on current smoking than the other groups (χ(2)=6.276, P=0.012), (χ(2)=8.245, P=0.004). Among the smokers, hypertensive patients presented lower rate (χ(2)=20.487, P<0.001) on intention of smoking concession, than the other groups. Patients with COPD showed greater intention in quitting smoking (χ(2)=6.085, P=0.048), than the other groups. Male patients with diabetes (χ(2)=9.219, P=0.010) or dyslipidemia (χ(2)=13.513, P=0.001) who had stopped smoking tobacco appeared having higher rates in keeping the current status. Results from logistic regression analyses showed that smoking was the risk factor for hypertension (OR=1.17), dyslipidemia (OR=1.25), COPD (OR=1.78), and asthma (OR=1.57). Conclusions: Patients with certain kinds of chronic diseases showed higher rate of current smoking and lower rate of quitting. Cigarette consumption appeared an important risk factor for patients with hypertension, dyslipidemia, COPD, or asthma in Beijing.

3.Computerized optic disc analysis with adjunct stereoscopic viewing of disc photographs.
Yonsei Medical Journal 1990;31(4):375-378
We have investigated the potential usefulness of stereoscopic viewing of optic disc photographs in marking the disc margin in computerized analysis with the Rodenstock Analyzer in 48 eyes of 26 patients with ocular hypertension or primary open-angle glaucoma. Marking of the disc margin without Method 1) and with the aid of stereoscopic viewing of disc photographs (Method 2) three consecutive times by one observer at the same sitting, and three subsequent topographic analyses of each method were done on each 48 eyes. The mean intraphotographic variabilities of such optic disc parameters as rim area, and cup volume with Method 2 were significantly less than those with Method 1 overall and in 16 eyes (33%) with poor video images having an ill-defined disc margin (p less than 0.05 for each), but not in 32 eyes (67%) with clear video images having a well-defined disc margin. Furthermore, the mean paired differences of rim area, disc area and cup volume between the two methods (Method 1 minus Method 2) were also statistically significant overall and in eyes with poor video images (p less than 0.05 for each).

We wanted to present the results of our experience with bilateral testis tumor and to suggest the effects of chemotherapy in suppressing the development of second primary testicular tumors. Between 1978 and 1997, 2,345 patients were treated for testicular tumor at The University of Texas M. D. Anderson Cancer Center. Of these, 2,107 had germ cell cancers. There were 22 (0.94%) cases of bilateral testicular tumor in the overall patient population and 21 (1.0%) cases among patients with germ cell cancer. We reviewed the medical records to determine the incidence of the histological subtype, the incidence of metachronous versus synchronous formation of contralateral tumors, and tumor stage in this patient population. We also examined the effect of chemotherapy in treating the first tumor and preventing the occurrence of a second tumor. Finally, we compared the effect of ultrasonography, serum tumor marker elevation, and physical examination in detecting second tumors. Only one contralateral germ cell tumor developed synchronously; all others developed metachronously. Fifty percent of first tumors were seminomas, compared to 55% of second tumors. The histologic concordance rate for first and second tumors was 35%. Tumor stage was higher among first tumors than second tumors. The majority of second tumors in patients who received chemotherapy for first malignancies tended to be metachronous seminomas. Ultrasonography detected 6 of 21 (28.6%) contralateral tumors before they were evident by physical examination or serum tumor marker elevation. Seminomas were more prevalent among patients with bilateral germ cell disease than patients with unilateral disease. Chemotherapy, when used as treatment for first tumors, may have some effect in preventing the development of nonseminomatous germ cell tumors in the contralateral testicle. Close follow-up of the contralateral testis with ultrasonography is essential for early detection of second tumors. The outcome for patients with bilateral testicular germ cell cancer is excellent, secondary to early detection.

To develop a more appropriate therapeutic strategy for treatment of nonpulmonary visceral metastatic testicular seminoma based on the International Germ Cell Consensus Classification, we reviewed the medical records of patients with nonpulmonary visceral metastatic testicular seminoma who were treated over a 20-year period. Only 15 (2.2%) of the 686 cases of testicular seminoma were nonpulmonary visceral metastatic seminoma. The median age of patients was 38 years (range, 22-53 years). Ten (67%) of the patients had an initial diagnosis of supradiaphragmatic or visceral metastatic disease. In addition to nonpulmonary visceral metastasis, all patients had lymph node metastasis as well, the majority of which involved the retroperitoneal lymph nodes. The median and mean progression-free survival durations after chemotherapy for advanced disease were 19 months and 63.7 months, respectively. Six patients (40%) survived, five relapsed after radiation therapy and four died of chemorefractory disease not dependent on the specific regimen. Although the number of cases reviewed in this study was small, we conclude that the choice of chemotherapeutic regimen among the current treatments for nonpulmonary visceral metastatic seminoma of testis primary does not present a different outcome. Therefore, multimodality therapies using new strategies or new agents are well indicated.

PURPOSE: The aim of this study is to analyze the outcome of a variety of treatments, including local surgical treatments, diverting stoma, and combined medical therapy, for patients with a rectovaginal fistula complicating Crohn's disease. METHODS: Between 1994 and 2003, twenty-one patients with a rectovaginal fistula complicating Crohn's disease from a prospectively compiled 422-patient Crohn's disease database were reviewed. RESULTS: All three patients treated by seton and fibrin glue recurred despite having relatively long tracts. Of six patients with infliximab treatment combined with a seton procedure, five patients had an improvement of their symptoms, but were not cured. Of eight patients with a transanal or endovaginal advancement flap techniques, three had successful closure, three eventually required a proctectomy, and two had a recurrent fistula without symptoms. Four (2 without any local treatments, and 2 with seton placement) of 16 patients who had a diverting stoma during treatment had successful closure. All proctectomy patients (n=8) had rectal involvement of Crohn's disease. Two patients who underwent a proctectomy with a presumptive diagnosis of ulcerative colitis and indeterminate colitis turned out to have Crohn's disease. Overall, except for the proctectomy patients, seven patients (54%) had successful closure, but six (four without symptoms, and two with symptoms) following a wide spectrum of treatments had recurrence after a mean follow-up of 44 months. CONCLUSIONS: Combining different treatments for a rectovaginal fistula in Crohn's disease can be successful in a reasonable number of cases. The presence of uncontrolled perianal sepsis and/or complicated anorectal problems is likely to lead to a proctectomy.

PURPOSE: The mechanisms, which alter urinary bladder muscle function during infectious cystitis, are poorly understood. The objective of this study was to identify potential resident targets for endotoxin lipopolysaccharide(LPS) within normal bladder smooth muscle and test the hypothesis that LPS induces an inflammatory response within the bladder muscle and that this is associated with a decrease in muscle contractility. MATERIALS AND METHODS: Male rats were studied 24 hours after a single bolus i.p. injection of LPS(15mg/kg). Whole-mount preparations of the bladder muscle were immunohistochemically stained for neutrophils(myeloperoxidase), macrophages(ED2), activated leukocytes(LFA-1) and mast cells(FITC-Avidin). Contractile activity was assessed from muscle strips of the bladder in response to bethanechol(0.3-300microM). Voiding frequency and urine volume for 24 hours were measured using metabolic cage. Cystometry was performed to measure the intravesical bladder pressure. RESULTS: Using the resident macrophage marker ED2, dense network of macrophages were observed within the bladder muscle of control and LPS treated rats. Few neutrophils(myeloperoxidase-positive cells, 2.3 +/- 0.38 cells, x200) were detected in whole-mounts of bladder muscle of control rats, while LPS pretreatment resulted in a significant increase in the number of neutrophils which demonstrate inflammatory response(10.8 +/- 1.70 cells, x200, p<0.001). LFA-1 immunohistochemistry demonstrated an increased presence of LFA-1 positive cells in bladder muscle of LPS treated rats, which had a morphology similar to both neutrophils and resident macrophages. The expression of LFA-1 is known as a marker of cells that are in an activated state. LPS pretreatment resulted in a significant reduction in bladder muscle contractions in response to bethanechol(i.e. control = 0.049 +/- 0.010 vs. LPS= 0.029 +/- 0.003 gr/mm2/sec, 100microM, p<0.05). Voiding frequency of LPS treated rats was significantly increased compared to that of control rats. In LPS treated rats, voiding phase representing bladder contractility in cystometry was observed. CONCLUSIONS: These data demonstrate that a single intraperitoneal injection of LPS initiates an inflammatory response within the bladder muscle that is associated with a decrease in the functional activity of the bladder. We hypothesize that secretions from the resident macrophages and extravasated leukocytes within the muscle cause the observed suppression in bladder muscle activity in vitro.

10.Tumor Necrosis Factor-Associated Protein 1 (TRAP1) is Released from the Mitochondria Following 6-hydroxydopamine Treatment.
Experimental Neurobiology 2014;23(1):65-76
Parkinson's disease (PD) is a common neurodegenerative disorder characterized by progressive degeneration of dopaminergic neurons in the substantia nigra pars compacta. Most cases are sporadic and its etiology is incompletely understood. However, increasing evidence suggests that oxidative stress and mitochondrial dysfunction may be involved in the pathogenesis of Parkinson's disease. The aim of this study was to investigate changes in mitochondrial protein profiles during dopaminergic neuronal cell death using two-dimensional gel electrophoresis in conjunction with mass spectrometry. Several protein spots were found to be significantly altered following treatment of MN9D dopaminergic neuronal cells with 6-hydroxydopamine (6-OHDA). Among several identified candidates, TNF receptor-associated protein 1 (TRAP1), a mitochondrial molecular chaperone, was released from the mitochondria into the cytosol in MN9D cells as well as primary cultures of dopaminergic neurons following 6-OHDA treatment. This event was drug-specific in that such apoptotic inducers as staurosporine and etoposide did not cause translocation of TRAP1 into the cytosol. To our knowledge, the present study is the first to demonstrate the drug-induced subcellular translocation of TRAP1 during neurodegeneration. Further studies delineating cellular mechanism associated with this phenomenon and its functional consequence may provide better understanding of dopaminergic neurodegeneration that underlies PD pathogenesis.
