AIM:To explore the effect of homocysteine (Hcy)-mediated endoplasmic reticulum stress on lipid metabolism in hepatocytes.METHODS: HepG2 cells used in the study were treated with 5 mmol/L Hcy. The concentrations of Hcy, triglycerides (TGE) and cholesterol (CHO) in the cells were measured. In high methionine diet-induced hyperhomocysteinemia C57BL/6 mice, the concentrations of TGE and CHO in hepatocytes were analyzed. The mRNAs and proteins expressions of glucose-regulated protein 78 (GRP-78) and sterol regulatory element binding protein (SREBP-1) were also assessed.RESULTS: The concentrations of Hcy and lipids (TGE, CHO) in HepG2 cells at different time point were elevated after treated with 5 mmol/L Hcy (P0.05,vs 0 week). The mRNAs and proteins expressions of GRP-78 and SREBP-1 in mice at different time point after high methionine diet were higher than that at 0 week (P

Background and purpose:Angiofollicular lymphoid hyperplasia(Castleman's disease,CD) is a rare kind of abnormal disease with lymphoid hyperplasia. We analyzed the clinical data of 21 patients with pathologically-confirmed CD. Methods:Twenty-one cases,including 10 males and 11 females with a mean age of 38.6 years,with CD were collected from January 1971 to December 2007 in this study. The disease was divided into localized type(n=19) and disseminated type(n=2) . The clinical data,CT images and pathological and surgical results were restrospectively analyzed. Results:All cases were categorized as hyaline vascular type. In 19 cases with localized type of CD,the lesion presented as a solitary soft-tissue mass with a mean diameter of 5.2 cm,located at the left and right hilus of the lung(n=3 and 2 respectively) or in the interior lung(n=3) ,in the thoracic wall(n=2) or in the mediastinum(n=9) . Two cases of disseminated type were characterized by many groups of thoracic lymphadenopathy with a mean diameter of 2.3 cm,without other organ involvement. On plain CT scan,the mean CT value was 42 Hu. After contrast administration,obvious homogeneous enhancement was observed in arterial phase with CT value of 112 Hu. The preoperative misdiagnosis by CT was 90.5%. Conclusion:CD have no specifi c CT characteristic,its verifi cation is mainly based on pathologic examination. Surgical resection for localized type of CD is curative,but for disseminated CD,multidisciplinary therapies are recommended.

ObjectiveTo explore the effects of insomnia on heart rate variety(HRV) in aged hypertension patients. Methods259 subjects were divided into healthy group (74 cases),simple hypertension group (71 cases),coexisting hypertension and insomnia group (114 cases) which was sub-grouped to ＜5 years,5-9 years and ≥-10 years according to the duration of insomnia.All subjects had 24 h recordings of ECG.The data of HRV time domain (SDNN,SDANN and ASDNN) were collected and compared.ResultsHRV time domain was lower in healthy group than in the other two groups (F=12.02,10.54 and 4.27,P＜0.01),and decreased more significantly in coexisting hypertension and insomnia group compared with simple hypertension group(P＜0.01).The values of SDNN and SDANN in 5-9 years and ≥ 10 years subgroups decreased as compared with ＜ 5 years subgroup (F=8.63 and 4.54,P＜0.01),and these values further lower in ≥10 years subgroup than in 5-9 years subgroup (P＜ 0.01 ). ConclusionsInsomnia may lead to more serious disorder of automatic nervous system and further aggravated disorders appear in the elderly with hypertension along with increasing years of insomnia.

Objective Data on applications and grants of general program on health science of National Natural Science Fund from Shanghai First People's Hospital,Shanghai Jiao Tong University (SFPH) during 2011-2014 were analyzed with an attempt to explore the ways to promote the funding rate.Methods x2 test and t test were performed,and a binary Logistic regression model was established to determine variables influencing the results of applications.Results There were 367 applications in SFPH during 2011-2014,86 of which were granted.The funding rate was higher than that of Department of Health Science.The total and highest impact factor of SCI articles published by applicants of granted programs were both higher than those of non-granted programs.The significance of these two factors in predicting whether an application will be granted was confirmed by the results of Logistic regression analysis.Conclusions SCI article is an important aspect of academic achievements of applicants,which is a prerequisite for an application to be granted.However,a scientific and innovative project may be critical for the outcome of an application.

In order to investigate the impact of fulvic acid (FA) on the hydroxylysyl glycosylation in collagen bio-synthesis, 40 NMRI mice were divided into two groups (n = 20 in each group, consisting 10 females and 10 males). The animal was maintained for two generations by different diets: control group with normal water and food and study group with water containing 30 mg/L FA and normal food. The second generation of the animal was slaughtered, and the biochemical parameters of collagen content and the degree of collagen hydroxylysyl glycosylation in skin, rib and tibia were detected by biochemical methods. The mean value of collagen in the study group was increased slightly, and no significant difference between study group and control group was found (P > 0.05), but the content of glucose-glactose-hydroxylysine (GGH) was significantly decreased in the study group in comparison with the control group (P<0.01). It was suggested that through the decrease of GGH 30 mg/L FA could inhibit the activity of galactosyl-hydroxylysylglucosyl-transferase and further disturb the post-translational modification of collagen intracellularly.

Objective To investigate the suitable mode of cognitive-behavioral therapy for lung transplant recipients during waiting for lung and evaluate the effect to improve patients' physical and mental state.Methods 50 cases were randomly divided into the experimental group and the control group,each group with 25 cases.The control group received conventional treatment.The experimental group received cognitive-behavioral therapy in addition to conventional treatment.SAS and vital signs were measured in the two groups on admission,2 weeks and 4 weeks after admission.Results The SAS score of the experimental group was lower than the control group 2 weeks and 4 weeks after admission and SAS score decreased as the intervention extended.The SBp of the experimental group was lower than the control group 4 weeks after admission.There was no significant difference of DBp between two groups.The heart rate of the experimental group was lower than the control group 4 weeks after admission.The heart rate of the experimental group was lower on 2 weeks and 4 weeks after admission than on admission.4weeks after admission,the respiratory rate of the experimental group was lower than the control group and on admission.Conclusions Cognitive-behavioral therapy can reduce the level of anxiety and keep vital signs stable with good feasibility and effectiveness.

Objective To study the inlfuence of the allicin on abnormal crypt focus(ACF). in Wister rat model. Methods 60 Wister rats were subcutaneous injected by dimethylhydrazine (DMH), according to 20 mg/kg weight, once a week, feeding 18 weeks continuously. All of the rats were randomly divided into allicin group and non-allicin group, each group was divided into three groups evenly, and put to death at 8, 16 and 24 weeks after medication separately. Large intestines were observed after dyeing. Results Large intestines were divided into ten equally, and all pieces were observed. ACF were almostly distributed in the middle and distal of the large intestines, about in 50%-80%.The basic situation of non-allicin group was as follows:ACF at 8 weeks was 63.97±1.22 on average per each, 16 weeks was 83.97±1.13, 24 weeks was 69.33±2.01. The basic situation of allicin group:ACF at 8 weeks was 9.4±1.12 on average per each , 16 weeks was 7.17±1.33, 24 weeks was 4.97±1.23.The occurrence of ACF in non-allicin group was higher than allicin group, the differences of incidence rate and number of ACF between two groups was significant (χ2=15.88,P<0.01).Conclusion Allicin can significantly reduce the number of ACF in Wister rats, lower the incidence of colorectal cancer, has prevention effect.

Objective To understand the current distribution and characteristics of advanced schistosomiasis patients who accepted medical assistance in Hunan Province in 2015,so as to provide the evidence for perfecting the policy and measures of the medical assistance to advanced schistosomiasis patients. Methods The patients who had been diagnosed as advanced schis-tosomiasis were verified and confirmed according to the standard of the medical assistance to advanced schistosomiasis patients in Hunan Province in 2015. The epidemiological survey was conducted to investigate the demographic characteristics,history of diagnosis and treatment,and medical assistance to these persons. Results There were 3850 advanced schistosomiasis patients who accepted the medical assistance in Hunan Province in 2015,and among them,2664 patients were male(69.19%),and 1186 were female(30.81%). Most of them(92.82%)came from the main schistosomiasis endemic areas,such as Yueyang, Changde and Yiyang. There were 2369 cases of ascites(61.53%),1466 cases of splenomegaly(38.08%),15 cases of colon proliferation and dwarf(0.39%). The mean age of advanced schistosomiasis patients who accepted the medical assistance was (62.94 ± 11.67)years old,with 64.31% of them being more than 60 years old. The age of initial diagnosis of advanced schistoso-miasis was(53.85 ± 21.32)years old,and it was concentrated in 40-60 years old(68.57%). The mean duration of advanced schistosomiasis was(9.58 ± 10.06)years,and it was mainly distributed in 10 years(75.95%). The mean duration from initial diagnosis of schistosomiasis to advanced schistosomiasis was(22.33 ± 14.20)years. The priority of the medical assistance to ad-vanced schistosomiasis patients was given to the county hospitals(76.57%);and the effective rate of assistance was 94.46%. To-tally 86.57% of the patients with advanced schistosomiasis got the medical insurance(rural cooperative medical care,urban medical care,etc.). Conclusions The burden of the medical assistance to advanced schistosomiasis patients is still heavy be-cause of many patients and low cure rate in Hunan Province. The ascites patients and high age patients should be the important objects of the medical assistance.
