Self-enhancement, the tendency to view oneself positively, is a pervasive social motive widely investigated in the psychological sciences. Relatively little is known about the neurocognitive mechanisms underlying this motive, specifically in social-evaluative situations. To investigate whether positive emotion regulation circuitry, circuitry involved in modulating positive affect, relates to the self-enhancement motive in social contexts, we conducted an functional magnetic resonance imaging (fMRI) study in a healthy young adult sample. We hypothesized that self-enhancement indices (state and trait self-esteem) would relate to greater functional connectivity between right ventrolateral prefrontal cortex (RVLPFC), a region implicated in emotion regulation, and the ventral striatum (VS), a region associated with reward-related affect, during a social feedback task. Following social evaluation, participants experienced stable or decreased state self-esteem. Results showed that stable state self-esteem from pre- to post-scan and higher trait self-esteem related to greater RVLPFC–VS connectivity during positive evaluation. Stable-state self-esteem also related to greater RVLPFC–VS connectivity during negative evaluation. Moreover, RVLPFC activation during all types of feedback processing and left VS activation during negative feedback processing was greater for participants with stable-state self-esteem. These findings implicate neurocognitive mechanisms underlying emotion regulation in the self-enhancement motive and highlight a pathway through which self-enhancement may restore feelings of self-worth during threatening situations.  相似文献

Background We have developed a new technique for treatment of intramucosal carcinoma which exceeds the standard indication for endoscopic mucosal resection and carcinoma invading the submucosa without lymph node metastasis that are located in the posterior wall of the stomach, which we refer to as laparoscopic intragastric full-thickness excision (LIFE) under flexible endoscopic control. Surgical Technique Three pigs were used for the study. Three trocars were used. The first trocar (trocar # 1) was placed in the subumbilical region to introduce the videoscope, whereas the second and third trocars (trocar # 2 and trocar # 3) were punctured percutaneously into the abdominal cavity. A straight needle with 3-0 silk suture was attached to a T-bar on the wire side and inserted into the abdominal cavity. An area adjacent to the lesion in the posterior wall of the stomach was pierced by the straight needle, which was then pulled into the stomach using the forceps of the endoscope. The T-bar, after being passed through the abdominal wall, was fixed outside the gastric wall, and trocar # 3 was repositioned in the stomach by the percutaneous transgastric route. The posterior wall of the stomach was pulled inward by the T-bar, and the lesion was removed by several excisions with laparoscopic stapling devices inserted through trocar # 3; extraction of the specimen was achieved through trocar # 3. The gastrotomy site was suture-closed using instruments positioned through trocar # 2 and trocar # 3 under laparoscopy. Conclusions Based on a feasibility study in pigs, the LIFE procedure can be performed for lesions of the posterior wall of the stomach.  相似文献

We report a case of collecting duct carcinoma (Bellini duct carcinoma) producing carcinoembryonic antigen (CEA). A 61-year-old man visited our hospital because of a left renal mass detected by ultrasonography in an other hospital. Computed tomography showed a low density tumor measuring about 3 cm in the left kidney. Angiography demonstrated a hypovascular tumor. The serum level of CEA was increased to 20 ng/ml. (normal < 7 ng/ml). Left radical nephrectomy was performed. Histological examination revealed collecting duct carcinoma with papillary growth (T1aN1M0). Cancer cells showed a positive immunohistochemical staining for CEA. Under a diagnosis of CEA-producing collecting duct carcinoma of the left kidney, the patient underwent systemic chemotherapy (M-VAC). The serum level of CEA decreased to the normal level after the nephrectomy, but six months postoperatively, metastatic bone tumor at the left pelvic bone was revealed on the plain film and at the same time, the CEA level was increased again.  相似文献

BACKGROUND: The amount of dehydroascorbic acid contained within total ascorbic acid (oxidized as well as non-oxidized forms) in plasma, hereafter referred to as the dehydroascorbic acid fraction, may be a measure of oxidative stress during haemodialysis. In the present study, we determined this fraction in chronic haemodialysis patients. METHODS: Using high performance liquid chromatography, dehydroascorbic acid and total ascorbic acid levels were measured in 80 maintenance haemodialysis patients for a period of > 2 years as well as in 49 controls, to examine a possible association of these compounds with clinical parameters and/or drugs taken by the patients. RESULTS: Dialysis patients who had an increased plasma urate level (P < 0.05) and had been taking allopurinol (P < 0.05) or NSAID (non-steroid anti-inflammatory drugs) (P < 0.01), and dialysis patients who were younger (< or = 55 years), as compared with older dialysis patients (P < 0.01), were found to have a lower dehydroascorbic acid fraction by multivariate analysis. Mean plasma dehydroascorbic acid levels and dehydroascorbic acid fractions were significantly lower in the younger haemodialysis patients (4.8 +/- 0.7 micromol/l and 28.4 +/- 3.9%) than in healthy younger controls (13.3 +/- 1.1 micromol/l and 41.1 +/- 1.8%) (P < 0.0001 and P < 0.01, respectively). Moreover, a correlation was found between plasma dehydroascorbic acid fraction and plasma lipid peroxide (r = 0.66, P < 0.01) in patients who had not been taking allopurinol and/or NSAID. CONCLUSION: We found that dehydroascorbic acid fraction was related to patients' age, plasma urate level and to taking allopurinol or NSAID. Dehydroascorbic acid fraction may be another indirect index of oxidative stress.  相似文献

OBJECTIVES: We investigated whether preoperative parameters predict pathological stage at radical prostatectomy for patients with clinically localized prostatic cancer. MATERIALS AND METHODS: We studied a total of 160 men with clinically localized prostatic cancer (less than or equal to clinical T2) who underwent radical rertropubic prostatectomy at Wakayama Medical University. Clinical Ts patients are not included in this study. Preoperative parameters include patient age, Body Mass Index, preoperative serum PSA value, biopsy Gleason score, clinical stage, the percent of positive biopsy cores (%PosBx) and the percent of positive biopsy cores on the dominant side (%DomPosBx). Univariate and multivariate analysis were performed to examine the prognostic significance of these preoperative parameters. Significant independent factors were combined to create a table to predict pathologically organ confined disease. RESULTS: Univariate analysis showed preoperative serum PSA value (p< 0.001), biopsy Gleason score (p =0.001), clinical stage (p = 0.026), %PosBx (p= 0.002) and %DomPosBx (p=0.003) were significantly related to the pathological stage. On multivariate analysis, serum PSA value (p< 0.01), biopsy Gleason score (p<0.05) and %DomPosBx (p<0.05) were significant independent predictors of pathological stage. CONCLUSION: We provide two model combinations using preoperative clinical factors, one is a combination of serum PSA and biopsy Gleason score and the other is a combination of serum PSA and %DomPosBx, which define a new preoperative model for predicting pathological organ confined prostatic cancer. These combinations are useful and provide important information for urologists to determine the appropriate treatment strategy for clinically localized prostatic cancer.  相似文献

Japanese patients with interstitial lung disease (ILD) sometimes die waiting for lung transplantation (LTx) because it takes about 2 years to receive it in Japan. We evaluated nutrition‐related factors associated with waiting list mortality. Seventy‐six ILD patients were hospitalized in Kyoto University Hospital at registration for LTx from 2013 to 2015. Among them, 40 patients were included and analyzed. Patient background was as follows: female, 30%; age, 50.3 ± 6.9 years; body mass index, 21.1 ± 4.0 kg/m2; 6‐minute walk distance (6MWD), 356 ± 172 m; serum albumin, 3.8 ± 0.4 g/dL; serum transthyretin (TTR), 25.3 ± 7.5 mg/dL; and C‐reactive protein, 0.5 ± 0.5 mg/dL. Median observational period was 497 (range 97‐1015) days, and median survival time was 550 (95% CI 414‐686) days. Survival rate was 47.5%, and mortality rate was 38.7/100 person‐years. Cox analyses showed that TTR (HR 0.791, 95% CI 0.633‐0.988) and 6MWD (HR 0.795, 95% CI 0.674‐0.938) were independently correlated with mortality and were influenced by body fat mass and leg skeletal muscle mass, respectively. It is suggested that nutritional markers and exercise capacity are important prognostic markers in waitlisted patients, but further study is needed to determine whether nutritional intervention or exercise can change outcomes.  相似文献

PURPOSE: Long-term results of radial osteotomy for Kienb?ck's disease seldom are seen in the literature. The purpose of this study was to report the minimum 10-year results and to compare them with the 5-year results to determine whether the favorable intermediate-term results were maintained. METHODS: Twenty-five patients who underwent radial osteotomy were followed-up for a mean period of 14.5 years. They were examined for pain, grip strength, and wrist range of motion (ROM). Through a review of clinical records, 5-year postoperative results were collected. The carpal height ratio and St?hl's index were measured and the x-rays were inspected for osteoarthritic changes. We devised an original lunate grade to evaluate radiologic improvement of the ischemic lunate. Overall results were evaluated using Cooney's wrist function score and Nakamura's scoring system for Kienb?ck's disease. The long-term results were compared with both the preoperative status and the 5-year results. RESULTS: Pain, ROM, and grip strength were improved significantly after surgery, and the results were maintained for a long period. Carpal height ratio and St?hl's index did not show significant improvements but ischemic lunate showed certain radiologic improvements with time by the lunate grade system. Osteoarthritic changes were observed in 54% of patients at 5 years and in 73% of patients at the final follow-up evaluation, but the arthrosis generally was mild and did not affect the clinical results. Cooney's wrist function score was excellent or good in 96% of the patients, and the results with Nakamura's scoring system for Kienb?ck's disease were excellent or good in 68% of the patients at the final follow-up evaluation. The percentages were the same 5 years after surgery. CONCLUSIONS: Radial osteotomy for Kienb?ck's disease is a reasonable treatment option and clinical improvement lasts for a long period of time. Although radiologic improvement was not drastic, the inner structure such as sclerotic change or bone cysts of the lunate improved with time, indicating healing of the ischemic lunate. Severe osteoarthritic change or proximal migration of the capitate can be avoided.  相似文献

BACKGROUND: Hidradenoma papilliferum is an uncommon benign tumor that is located almost exclusively in the vulvar and anal areas. It is usually very small and asymptomatic, and to make a correct diagnosis is clinically very difficult. Occasionally the tumor becomes elevated to form a reddish brown papillary mass, and the surface ulcerates, which may erroneously suggest malignancy. OBJECTIVE: We report a case of a large, perianal hidradenoma papilliferum with suspected malignancy in a young Japanese female. RESULTS: A 22-year-old female had been aware of a perianal nodule for approximately 1 year. Examination of the perianal area revealed a wide pedunculated, reddish nodule with several white maculae. It was ulcerated and bleeding, 2.0 x 1.2 x 0.8 cm in size, and located in the 3 o'clock position. The nodule was totally excised with a narrow margin. The histopathologic diagnosis was hidradenoma papilliferum. No recurrence was observed for 23 months. CONCLUSION: When dermatologists encounter tumors of the anogenital area of adult females, it is important to keep hidradenoma papilliferum in mind as the differential diagnosis. Dermatologists should recognize that the tumor is benign, eliminating the need for wide resection.  相似文献

Background

Despite recommendations on how to prevent baseball injuries in youths by the Japanese Society of Clinical Sports Medicine, shoulder and elbow pain still frequently occurs in young baseball players. We conducted a questionnaire survey among baseball players at elementary schools across the country to understand the practice conditions of players, examining the risk factors of shoulder and elbow pain in baseball players.

Methods

The questionnaire survey was conducted among elementary school baseball players as members of the Baseball Federation of Japan in September 2015.

Results

A total of 8354 players belonging to 412 teams (average age: 8.9) responded to the survey. Among 7894 players who did not have any shoulder and/or elbow pain in September 2014, elbow pain was experienced in 12.3% of them, shoulder pain in 8.0% and shoulder and/or elbow pain in 17.4% during the previous one year. A total of 2835 (39.9% of the total) practiced four days or more per week and 97.6% practiced 3 h or more per day on Saturdays and Sundays. The risk factors associated shoulder and elbow pain included a male sex, older age, pitchers and catchers, and players throwing more than 50 balls per day.

Conclusions

It has been revealed that Japanese elementary school baseball players train too much. Coaches should pay attention to older players, male players, pitchers and catchers in order to prevent shoulder and elbow pain. Furthermore, elementary school baseball players should not be allowed to throw more than 50 balls per day.
