Objective To summarize the effective managements of cardiopulmonary bypass (CPB) duing open heart surgery in the elderly patients by comparing with that of the non-elderly groups. Methods Pre-operative common data and the managements for 84 elderly patients during the cardiopulmonary bypass from January 1998 to June 2000 were analyzed retrospectively, and the same data of 80 non-elderly patients(40-60 years old) who underwent CABG during the same period were also randomly selected and compared. Results The elderly patients were usually combined with hypertension, diabeties, chronic kindney failure and abnormal pulmonary function. The average time for CPB and clamping time for the ascending aorta were (115.6?27.0)min and (80.4?32.2)min, respectively. The average lowest nasopharyngeal and anal temperature was (29.8?1.4)℃ and (30.7?0.8)℃, respectively, showing no significant difference comaparing with those of the non-elderly patients. There was significant difference between the two groups in the transfusion of shed blood(P

Purpose: To study the effect of personality on the mental adjustment of breast cancer patients during operation. Methods: Forty three breast cancer patients were examined by the Eysenck Personality Questionnaire (EPQ) for their personality before operation, and by the Mental Adjustment to Cancer Scale ( MAC) for their mental adjustment reaction before and after operation. Results: ANOVA repeated analysis revealed that the patients characterized by high Psychoticism showed higher scores on Fatalism, and the patients characterized by low Lie showed higher Hopelessness during operation. Conclusions: In the treatment of breast cancer patients, it is necessary to give appropriate psychological treatment according to the patients's individual characteristics.

Objective To study the correlation between alopecia areata and the susceptibility genes identified in our previous study with Han Chinese population. Methods The study performed an independent replication study using 736 cases and 1 840 controls. DNA was extracted from peripheral blood leukocytes by salting out with saturat-ed NaCl solution according to standard methods. The evidence for association had been obtained from former gene study. Then a fine-mapping study and genotyped the locus with an additional 17 SNPs were performed. Data were analyzed with the use of Plink 1. 07 software. Results Only one SNP achieved nominal significance, rs3087243 (P = 0. 041, OR = 1. 18, 95% CI = 1. 01 ~ 1. 38). The other 16 genes (TLR1, DMBT1, CHIT1, GBP4, CIITA, IL31RA, CD96, INPPL1, MASP2, IL-13, KIAA0350, PTPN22, SPATA5, TRAF1 / C5, IL1A, IL2R) failed. A further stratification analysis of alopecia areata was adopted, including the analysis of family history, the age of on-set and the severity of alopecia areata. The stratification analysis revealed that the age of onset > 20 years achieved nominal significance P < 0. 05 for one SNP, rs2416808 (P = 0. 018, OR = 1. 35, 95% CI = 1. 05 ~ 1. 74), where-as, the other results were of no statistical significance. Conclusion The results indicate that 17 SNPs may not be associated with AA in Han Chinese population. Further study should be performed in a larger Han Chinese sam-ples.

Objective To investigate the prevalence of osteoporosis,osteopenia,fall and brittle fracture and their associated factors in men aged 80 years and over.Methods In a prospective study,184 study subjects with good self-care ability aged 80 years and over were enrolled.The questionnaire included living habits,falls,comorbidities,related symptoms and medicines.The bone mineral density,hand-grip strength,gait speed,timed up and go test(TUG),chair rising test(CRT),bone turnover markers and related hormones were measured.Binary Logistic regression model was used to analyze associated factors for osteoporosis,osteopenia,fall and brittle fracture.Results The prevalence of osteoporosis (OP)and osteopenia(OPA) were 12.5 ％ (23/184) and 45.1％ (83/184) respectively in this study.The height,weight and body mass index were lower,and serum levels of procollagen type 1 N terminal propeptide(P1NP)and C-telopeptides of type 1 collagen(s-CTx)were higher in osteoporosis group than in normal bone mass(NBM) group(P＜0.05,P＜0.01).The estradiol levels were lower in OP and OPA group than in NBM group(P＜ 0.05).The risk factors for OP and OPA included smoking(OR =3.607,P＜0.05),decreased body weight (OR=0.823,P ＜ 0.05) and elevated S-CTx level (OR =12.427,P ＜ 0.01).55.4％ (102/184) of study subjects had fall history after 80-year old.The prevalence of fragile fracture was 17.4％ (4/23),18.1 ％ (15/ 83)and 3.8％(3/78)in OP,OPA and NBM groups respectively,with total prevalence of 12.0％ (22/184).The risk factors for fragile fracture were a decreased total hip BMD(OR 0.017,P＜0.05)and fall history after 80-year-old(OR 13.126,P ＜ 0.05).Conclusions Based on associated factors of osteoporosis,osteopenia,falls and fragile fracture in male aged 80 years and over,the primary and secondary prevention of osteoporosis may need a comprehensive geriatric intervention including lifestyle adjustment,fall prevention and pharmacologic treatments.

Objective To study the ches t X-ray and CT appearance of pulmonary nontuberculosis mycobacteria (NTMB) Methods The chest X-ray findings of 22 cases with cultures positive for pulmonary nontuberculosis mycobacteria were reviewed, 10 cases had CT scans simultaneously All abnormalities and predominant lobar involvement were recorded The findings of chest X-ray and CT were compared Results The chest X-ray showed that air space consolidation ( n =19) and cavities ( n =18) were most frequently seen, nodules ( n =12) and linear disease ( n =14) were observed too The abnormalities involved bilateral multiple lobes, the right lung was more frequently involved than left, and upper lobe was involved more than lower ones Multiple manifestations were often co-existing ( n =19) On CT scans, nodule was the most frequent finding ( n =10), air space consolidation ( n =8) and cavity ( n =8) were other common findings In addition, bronchiectasis ( n =5), “tree in bud” sign ( n =3), and mediastinal lymphadenopathy ( n =2) were also seen on CT but not on chest X-ray Conclusion Air space consolidation, cavity, nodule, fibrosis, bronchiectasis, and “tree in bud” are major abnormalities of chest image The image abnormalities of pulmonary NTMB are indistinguishable from those of secondary pulmonary TB Multiple co-existing manifestations may be the characteristic findings of pulmonary NTMB infection

Objective To investigate CT features of similar Hexheimer's reaction during initial treatment of active pulmonary tuberculosis. Methods The similar Hexheimer's reaction in 44 patients diagnosed by clinic and follow-up CT scans were retrospectively reviewed by three radiologists. Results During initial treatment of active pulmonary tuberculosis, development of radiographic progression were observed in 57 foci, including 28 pulmonary lesions increased at the site of their original lesion or new opacities elsewhere, ipsilateral or contralateral to the original lesion or both, 10 lesions related to the pleura (pleural effusion, pleural tuberculoma), 15 lymphadeneetasis, 3 thymus reactions, and 1 cardiac pericardium thickening, respectively. These reactions appeared from the 20 days to 3. 5 months, then with continuation of the initial chemotherapy for 1.0-3.0 months, the radiographic response was excellent with the areas of progression and the original lesions demonstrating resolution or improvement. Conclusion The CT appearances of similar Hexheimer's reaction during initial treatment of active tuberculosis are specific to a certainty.

Objective To investigate the expression of substance P ( SP) and neurokinin-1 recep-tor (NK1R) in patients with breast cancer and to further understand the correlations of them with the clinico-pathological features and the prognosis of breast cancer.Methods SP levels in serum samples and superna-tants of breast cell culture were measured by ELISA.The expression of total NK1R, full-length NK1R (NK1R-FL) and truncted NK1R (NK1R-Tr) in 82 patients with breast cancer and 30 patients with breast hyperplasia were detected by using immunohistochemistry and Western blot.Results The levels of SP in patients with breast cancer were higher than those in patients with breast hyperplasia and healthy subjects ( P<0.05) .The expression of NK1R-FL was inhibited, while the expression of NK1R-Tr was significantly en-hanced in breast cancer tissues as compared with those in normal and hyperplastic breast tissues (P<0.01). Compared with patients with ductal carcinoma in situ ( DCIS ) , patients with invasive ductal carcinoma (IDC) showed a decreased expression of NK1R-FL, but an increased expression of NK1R-Tr (P<0.05). The stages of breast cancer classified by using the TNM system showed a negative correlation with NK1R-FL expression, but positive correlations with the expression of NK1R-Tr and SP (P<0.01).Moreover, the en-hanced expression of NK1R-Tr and SP and suppressed expression of NK1R-FL were positively related to lymph node metastasis and high expression of vascular endothelial growth factor ( VEGF) , human epidermal growth factor receptor 2 ( HER2) and Ki-67, but negatively related to the expression of estrogen receptor (ER) and progesterone receptor (PR) in breast cancer tissues (P<0.05).The expression of NK1R-FL and NK1R-Tr showed no significant correlation with age, histological grades and the expression of P53 in breast cancer tissues (P>0.05).Conclusion The invasion and metastasis of breast cancer showed a negative cor-relation with the expression of NK1R-FL, but a positive correlation with the expression of NK1R-Tr and SP.

This study is to investigate the effects of sophoridine on NF-kappaB signaling pathway in kidney tissue of endotoxemia mice and the mechanism involved. BALB/c mice were challenged with lipopolysaccharide (LPS) caudal vein injection, then sophoridine was administered by intraperitoneal injection. Totally 50 mice were divided into 5 groups: control group, LPS model group, sophoridine treatment 12 mg x kg(-1) group, 6 mg x kg(-1) group and 3 mg x kg(-1) group. All animals were sacrificed at 6 hours after treatment. Kidney and blood samples were harvested. IKKbeta mRNA and TNF-alpha mRNA expression of renal tissue was measured by the reverse transcription polymerase chain reaction (RT-PCR), and phosphorylation IKKbeta protein (pIKKbeta) was detected by immunohistochemistry. NF-kappaB P65 protein expression and distribution of renal tissue were observed by Western blotting and immunofluorescence laser confocal microscopy. Serum TNF-alpha level was detected by radioimmunoassay. The results showed that the sophoridine significantly reduced the expression of IKKbeta mRNA and pIKKbeta protein, and inhibited the expression of NF-kappaB P65 protein and decreased the entry nuclear rate of NF-kappaB P65 in the renal tissue of endotoxemia mice. Thereby the renal TNF-alpha mRNA expression and serum TNF-alpha level were significantly reduced. These results suggest that sophoridine could inhibit inflammatory reaction induced by LPS through inhibiting activation of NF-kappaB signaling pathway.

Purpose:To assess the value of 99m Tc tetrofosmin SPECT in discrimination of malignant from benign breast mass.Methods:The trial was prospective, blind and diagnostic. From 2000.6 to 2001.12, one hundred one consecutive patients with breast mass detected by clinical examination were included. After injection of 740 MBq 99m Tc tetrofosmin intravenously in the arm contralateral to the breast lesion, 99m Tc tetrofosmin SPECT was performed additional to the regular diagnostic procedure. All patients underwent operation within one week. Using histological assessment as a golden standard, we calculated sensitivity, specificity, positive and negative predictive value for 99m Tc tetrofosmin SPECT of the breast mass. Results:The sensitivity for palpable breast lesions was 86 3%, specificity 84.0%, positive and negative predictive value were 84.6% and 85.7% respectively. Conclusions:The results suggested that 99m Tc tetrofosmin SPECT is a valuable tool for the evaluation of palpable breast lesions.
