Objective To study of relationship between elderly people's alexithymia and mind-reading. Methods There were 108 old people over 70 years old, tested by mind-reading,cognitive ability and twenty-item Toronto alexithymia scale. Results There were significant difference in mind-reading(16.00±4.84, 19.36±2.91,t =3.38,P ＜0.01), memory span(5.80±1.42,7.18±1.13,t =4.28,P ＜0.01), working memory( t =4.05,P ＜0.01),processing speed( t =-4.80,P ＜0.01) between high and low alexithymia groups.Alexithymia scores were negatively related to the scores of mind-reading, memory span,working memory,processing speed,correlation coefficient was 0.227( P <0.05),-0.377( P <0.01),-0.334( P <0.01),-0.470( P <0.01),respectively. With mind-reading,cognitive processing and educational level as independent variables,with total scores, F1, F2, and F3 of TAS as dependent variable,respectively,the regression equation of total scores was significant( F =8.594,P ＜0.01), and the one of F1 was significant( F =8.796,P ＜0.01),but the one of F2( F =1.735,P ＞0.05) and F3( F =1.181,P ＞0.05) was not significant. Conclusion Elderly people's alexithymia is negatively related to mind-reading and several cognitive abilities. Mind-reading could affect emotional recognition, but not affect emotional description and export-oriented thinking.

To research the expressions of IL-5,granulocyte macrophage colony stimulating factor(GM-CSF) in the asthmatic guinea pig pulmonary tissue and influence of triptolide on the expression,30 guinea pigs were divided at random into three groups:the asthma group(n=10),treated group(n=10) and control group(n=10).The expression levels of the IL-5,GM-CSF mRNA were detected by using in situ hybridization method.The results showed that the expressive intensities of IL-5,GM-CSF mRNA in asthma group were 36 38?7 65 and 32 78?9 43 respectively;the treated group were 17 46?7 32 and 18 92?6 38 respectively;control group were 13 82?5 43 and 18 27?7 45 respectively.The expressive intensities of IL-5,GM-CFS mRNA in asthmatic group were obviously higther than those of both treated and control groups,there was significantly difference between two groups(P

Objective To observe the effect of ghrelin on the expression of procollagen type Ⅰ and alpha smooth muscle actin (α-SMA) synthesis in vitro cultured human hepatic stellate cell (HSC-LX2) stimulated by Platelet-derived growth factor-BB (PDGF-BB).Besides,the effect of PI3K-AKT pathway was studied.Methods Cultured LX2 were intervented and jointing intervented according to the different ghrelin concentration by ghrelin and PDGF:control group,0.1 μmol/L Ghrelin group,10 μg/L PDGF group,0.05 μmol/L Ghrelin +10 μg/L PDGF group,0.1 μmol/L Ghrelin + 10 μg/L PDGF group,0.15 μmol/L Ghrelin + 10 μg/L PDGF group.Culture HSC-LX2 in vitro,joint intervention cells with different concentrations.Procollagen Ⅰ mRNA expression were detected by Polymerase chain reaction (PCR),besides,α-SMA and AKT expression were detected by Western blot in each groups.After treatment by PI3K specific inhibitor LY294002 in LX2,three groups were divided into PDGF,Ghrelin + PDGF and LY294002 + Ghrelin +PDGF.Procollagen Ⅰ mRNA expression were detected by PCR,and α-SMA was detected by Western blot.Results PCR results showed that procollagen Ⅰ expression in PDGF treated group was significantly higher than the control group ((6.91 ± 0.46) vs.(1.00 ± 0.08),P ＜ 0.05),so PDGF can promote the expression of procollagen type Ⅰ.Procollagen Ⅰ mRNA expression between ghrelin group(0.60±0.13) and blank control group had no significant change(P＞0.05).Procollagen Ⅰ mRNA expression between different concentrations of Ghrelin and PDGF (3.11 ± 0.28,2.03 ±0.23,0.70 ± 0.06) was significantly reduced than PDGF group.The difference was statistically significant (P ＜0.05),and with the increase of the ghrelin concentration of the inhibition,the effect was more obvious in a concentration dependent manner.Western blot showed that α-SMA expression was lower in Ghrelin +PDGF group than PDGF group.AKT expression was higher in Ghrelin +PDGF group than PDGF group,indicating that PI3K-AKT may participate in the anti-fibrosis effect of ghrelin in LX2.After treatment of PI3K specific inhibitor,procollagen Ⅰ expression in LY294002+Ghrelin +PDGF group was significantly higher than Ghrelin +PDGF group((4.13±0.21) vs.(2.34±0.25),P＜0.05).Western blot also showed that α-SMA expression was higher in LY294002 + Ghrelin + PDGF group than Ghrelin + PDGF group.It was suggested that after inhibitation of PI3K,the anti-fibrosis effect of ghrelin in LX2 was attenuated.Conclusion After stimulated by PDGF in hepatic stellate cell,ghrelin can inhibit procollagen type Ⅰ and alpha-SMA synthesis in the process of hepatic fibrosis via PI3K-AKT pathway,thus,ghrelin may become one of the new ways of prevention and treatment of liver fibrosis.

Objective:To explore the mechanism for the immune cross-reaction between crabs and shrimps.Methods:The cross-reactivity between shrimps and crabs was observed by inhibition of ELISA and Western blot.Results:The protein constituents were similar where their genus relationship was closer in shrimps and crabs.There were the same bands at 20,36,38,44,68,75,and 85 kD of molecule weight.The protein at 36 kD was the main allergen for shrimps and the proteins at 36,66 and 85 kD were the main allergens for crabs.S.serrata and M.nipponense could inhibit the allergic response of various kinds of shrimp and crab in a concentration-dependent pattern.Conclusion:There is a strong immune cross-reaction between different species of shrimp and crab in 36 000.

Objective To review and summarize the experience of surgical treatment of primary cardiac tumors in children from a heart center of China.Methods The pathological studies of 11 cases of primary cardiac tumor (except myxoma) were retrospectively analyzed.Results The mean age for all patients was (23 ± 16) months,and the average weight was 3.1 ～ 15.3 (13 ± 5.7) kg at the time of the established diagnosis.The most common reason of admission was the heart murmur,and the most common pathological type of cardiac tumors was rhabdomyoma (5 cases),followed by fibrous tumor (3 cases),angiofibroma (2 cases),and fibrosarcoma (1 case).All of the patients underwent tumor resection due to the corresponding symptoms.One of them,the operation findings showed the aortic root,superior vena and sinoatrial node were involved into the tumor body,and therefore,the tumor debark resection was performed and the child died 2 years later due to the remained tumor progression.One of other children (pericardial fibrosarcoma) died 1 year late because of tumor recurrence.The others were followed-up for duration of 2 ～9 years and all kept in good condition.Conclusions The surgical resection is mandatory for children suffering with symptomatic primary cardiac tumors and the short-term and long term surgical outcomes for the majority are acceptable.

Colonoscopy has been accepted as the standard method for evaluation of colon and rectum,its success rate depends on the quality of bowel preparation. Aims:To evaluate the cleanliness and tolerance of fractionated dose versus single dose polyethylene glycol electrolyte solution( PEG-ES) bowel preparation regimens for colonoscopy. Methods:A total of 427 consecutive asymptomatic individuals undergoing colorectal cancer screening were enrolled and randomly assigned into 2 groups. Subjects in group A drank 1. 5 L PEG-ES on the eve and 4 hours before colonoscopy, respectively;subjects in group B received a single dose of 3 L PEG-ES 5 hours before colonoscopy. Score and degree of Boston bowel preparation scale(BBPS)and PEG-ES related adverse effects of the two groups were assessed and compared. Results:There were no significant differences in gender,age and cecal insertion rate between group A and group B(P ﹥ 0. 05). Score of BBPS was significantly higher in group A than in group B(P ﹤0. 01). Both regimens met the requirement of conventional colonoscopy,however,the cleanliness of colon was graded as excellent in more subjects of group A( P ﹤ 0. 01),and less subjects of group A complained PEG-ES related nausea(P ﹤0. 05). Logistic regression analysis revealed that the PEG-ES drinking pattern was associated with cleanliness of colon and occurrence of nausea( P ﹤ 0. 05). Conclusions:Fractionated dose PEG-ES regimen provides a better colonic cleansing quality and tolerance for bowel preparation of colonoscopy,which is superior to that of single dose regimen.

Tuberculosis (TB) is an infectious disease endangering people’s health around the world ,and diagnosis and ra‐tional treatment are the key to control TB .However ,currently there is no diagnostic golden standard for latent tuberculosis in‐fection (LTBI) .The tuberculin skin test and IFN‐gamma release analysis are regarded as effective methods for TB diagnosis , which is based on host’s cellular immune response to mycobacterial antigens .But the two methods are not perfect ;neither test can make a clear distinction between latent infection and active TB .Flow Cytometry (FCM ) has been widely used in the field of clinical medicine .In recent years ,substantial advances have been achieved in the fields of TB diagnosis and evaluation of treat‐ment efficacy by using the FCM intracellular cytokine detection technology .In this paper ,we will review the latest progress in tuberculosis diagnosis research by using flow cytometry in recent years .
