Protection for privacy is the guarantee for sustaining personal dignity and individual liberty.Protection for patients' privacy has a long history and is of great realistic significance.However,patients with A H1N1 Influenza are facing the risk of exposing privacy in current circumstances.This paper argues that the privacy protection for this particular population is beneficial both for social and public interests,and also can be justified from an ethical perspective.

Under the background of current strained doctor-patient relationship,the new Criminal law Amendment stipulates that people who makes medical troubles shall be persecuted for their criminal liability in order to reconstruct harmonious doctor-patient relationship.Through questionnaire survey,this paper investigated the cognitive status,cognitive channel,and improvement measures of doctor-patient relationship after the new Criminal law Amendment in college students in Nanjing,analyzed the causes,and discussed the possible path to construct harmonious doctor-patient relationship.Doctor-patient communication should be enhanced;patients should seek medicine service rationally;hospitals should effectively deal with complaints and disputes and vigorously strengthen the enforcement strength of the new Criminal law Amendment.

Objective To explore the effects of the community-based rehabilitation on schizophrenia. Methods 100 patients with schizophrenia from 4 communities were assigned to intervention group (n=50) and control group (n=50). The intervention group accepted comprehensive intervention for 6 months. All the patients were followed up for 12 months, and assessed with the Positive and Negative Symptoms Scale (PANSS), Personal and Social Function Scale (PSP), the General Quality of Life Inventory (GQOLI-74). Results 48 cases of the intervention group and 44 of the control group finished the study. The scores of negative symptoms and general spirit pathology were less in the intervention group than in the control group (P<0.01). The score of PSP was more in the intervention group than in the control group (P<0.01), as well as the total score and score of dimensions of physical function, mental health and social function (P<0.05). Conclusion Community-based rehabilitation can control the mental symptoms, and improve the social function and the quality of life of patients with schizophrenia.

OBJECTIVETo investigate the diagnostic value of imageology of giant cell tumour of tendon sheath (GCTS) including X-ray, CT and MRI.

METHODSThirty-five patients with GCTTS confirmed by operation and pathology were retrospectively analyzed. There were 16 males and 19 females. The average age was 39.4 years, ranged from 7 to 66 years. All the patients underwent X-ray examination, 8 patients underwent CT examination, and 16 patients underwent MRI examination.

RESULTSThere were 2 patients in knee joint, 6 patients in ankle joint, 1 patient in capitulum radius, 2 patients in wrist joint, 14 patients in hand and 10 patients in foot. Ten cases were the diffuse form, and 25 cases were the focal form. The X-ray results: the slightly high density soft tissue mass surrounding the bone were shown in 32 cases, 3 cases were normal. The bone erosion were shown in 9 cases, the obvious destruction of bone were shown in 5 cases. CT results: The soft tissue mass and the destruction of bone were shown clearly. MRI results: On T1WI, the signal intensity of GCTTS almost was similar to those of skeletal muscle in 9 cases and was slightly lower than those of skeletal muscle in 7 cases. On T2WI, the signal intensity presented mainly hypointensity with patchy isointensity or hyperintensity signal. A little of fluid was shown in 6 cases.

CONCLUSIONX-ray can demonstrate the lesion and erosion of bone, destruction of bone can clearly be shown on CT. The low intensity signal on MRI T1WI and T2WI is the characteristic appearance of GCTTS. And it can clearly show the lesion range and type of GCTTS.

OBJECTIVESince application of pediatric gastroscopy in the mid-nineteen nineties, there has been a trend that the prevalence rates of pediatric gastritis and duodenal ulcer (DU) are increasing. The diagnosed rate of pediatric gastritis has accounted for 85% - 95% of the total number of children who received gastroscopy, and the rate of DU accounted for 8% - 22%. Such a high rates of the diseases may influence the development of the children severely. However, the etiology and pathogenesis of pediatric chronic gastritis and DU have not been completely elucidated. The disordered gastrointestinal hormones play a crucial role in the pediatric chronic gastritis and DU. This study focused on the expression of gastrin (GAS), somatostatin (SS) in the mucosa of gastric antrum and PCNA and Fas-L in the sinus ventriculi and their possible roles in the pathogenesis of pediatric chronic gastritis and DU.

METHODThe sinus ventriculi mucosal samples of 83 cases were collected via gastroscopic biopsy from the hospital during the recent two years and the cases were divided into five groups: group A, chronic superficial gastritis, Helicobacter pylori (Hp)(+); group B, chronic superficial gastritis, Hp(-); group C, DU, Hp(+); Group D, DU, Hp(-); Group E, normal sinus ventriculi mucosa, Hp(-). Immunohistochemical staining (En Vision) was carried out for GAS, SS, PCNA and Fas-L, and positive cells of each slide were counted (x 400). Statistically significant differences among groups for continuous data were assessed with the software SPSS10.0.

RESULTSThe expressions of GAS and SS in the groups A through E had no significant difference. The expression of PCNA in group A was significantly higher than that in group B (P < 0.05), and no significant differences were found among the other groups. There were no significant differences in expressions of Fas-L among the five groups.

CONCLUSIONThere seems to be an increasing tendency in the expressions of GAS and SS in children with chronic gastritis and duodenal ulcer. Hp infection promotes the multiplication of the sinus ventriculi mucosal epithelium cells in the pediatric chronic gastritis.

OBJECTIVETo study the expression and pathological implication of transforming growth factor-1 (TGF-1) and endothelin-1 (ET-1) in intraacinar pulmonary arterioles of children with congenital heart disease and pulmonary hypertension (HP).

METHODSForty-one children with left-to-right shunt congenital heart disease were studied including 25 cases of HP (group A), 16 cases without HP (group B) and 10 children without congenital heart disease as the contols (group C). Expression of TGF-beta1 mRNA and ET-1 mRNA in intraacinar pulmonary arteriolar (IAPA) was studied using in-situ hybridization and image pattern analysis of their absorption values (A value). Changes of the intraacinar arterioles and lung tissue were studied by elastic fiber staining and electronic microscopy respectively.

RESULTS(1) There was a significant difference in the amount of intraacinar pulmonary arterioles (partial-muscular and muscular) counted in either group A or B in comparing with that of group C (F values 149.96 and 142.01 respectively, P < 0.01); (2) Electronic microscopy demonstrated endothelial proliferation of the small arteries, thickening of arteriolar wall, increased density of collagen fibers at adventitia and increased thickness of the capillary basal membrane; (3) The A value of TGF-beta1 mRNA expressed in the pulmonary arterioles of groups A and B by in-situ hybridization were 0.1988 +/- 0.0498 and 0.1098 +/- 0.0428 respectively, however, the expression was weak in group C (A value: 0.0578 +/- 0.0096). There were all significant between each two groups (F = 45.95, P < 0.01). The expression of ET-1 mRNA was markedly increased as well in the endothelial cells of pulmonary arterioles in both groups A and B, with A values of 0.1692 +/- 0.0205 and 0.1004 +/- 0.0140 respectively, whereas the expression was weak in group C (A value of 0.0746 +/- 0.0119). There were all significant between each two groups (F = 139.996, P < 0.01).

CONCLUSIONSThe number of intraacinar pulmonary partial-muscular and muscular arterioles in patients with left-to-right shunt congenital heart defect is drastically increased, along with marked restructuring of the pulmonary vasculatures. In addition, there seems a correlation present between the overexpression of TGF-beta1 mRNA and ET-1 mRNA in intraacinar pulmonary arterioles and the occurrence of pulmonary hypertension in patients with congenital heart disease.

Objective To explore the diagnostic value of Alzheimer-associated neuronal thread protein(AD7C-NTP)and olfactory function in the differentiation of three types of dementia,and to evaluate their clinical application value.Methods Mini-Mental State Examination (MMSE)and Montreal Cognitive Assessment(MoCA)were applied to evaluate cognitive function of all subjects with Alzheimer disease(AD),frontotemporal dementia (FTLD),or mixed dementia (MD).Enzyme-linked immunosorbent assay(ELISA)was used to detect the expression levels of AD7c-NTP in urine.T&T test method was applied to detect the olfactory function.Spearman rank correlation was used to evaluate the correlation of urine AD7c NTP with MMSE and MoCA scores.Results There was no significant difference in the demographic profile (except age)among three types of dementia of AD,FTLD and MD(F =4.05,P =0.02).Among the three dementia groups,the mean age of the MD group was highest.The statistically significant difference in MMSE scores was found among the three groups(F 3.79,P=0.03),while there was no significant difference inMoCAand NPI scores among the three dementia groups.The levels of the urine AD7c-NTP were different among the three dementia groups,but without statistical significance(H 1.25,P =0.53).Additionally,the FTLD group had the highest urine AD7c NTP level.Spearman rank correlation analysis showed no correlation of AD7c-NTP with MMSE and MoCA(r =0.18,P =0.25;r =0.14,P =0.39,respectively).No differences in olfactory function of the recognition domain(H =3.40,P=0.18)and in the detection domain(H =2.07,P=0.36)were found among three dementia groups of AD,FTLD and MD.Conclusions The level of urine AD7c-NTP is not of clinical significance in differentiating three types of dementia,and it is not correlated with the MMSE and MoCA scores.This study fails to find the clinical value of olfactory function test for distinguishing three types of dementia.

BACKGROUNDAngiogenesis is the formation of new blood vessels to supply nutrients to tumors. Vascular endothelial growth factor (VEGF) and cluster of differentiation 34 (CD34) are important signaling proteins involved in angiogenesis. Many studies have demonstrated that VEGF and CD34 are related to tumor progression. This study focused on the relationship between VEGF, CD34, and perioperative hemorrhage in patients with gastric cancer.

METHODSTo observe the relationship between VEGF and CD34, we tracked 112 patients with advanced gastric cancer for 5 years to assess factors related to hemorrhage, using immunohistochemistry. The results were subjected to statistical analysis using a 2 × 2 contingency table, logistic regression, and receiver operating characteristic (ROC) test.

RESULTSThe concentrations of VEGF and CD34 were critically correlated with perioperative hemorrhage and neural invasion in patients with gastric cancer (P < 0.05). Expression of VEGF and CD34 was related (P < 0.05, χ2 = 6.834). VEGF and CD34 co-expression strongly increased the risk of preoperative bleeding (area under the ROC curve >0.7, P < 0.05).

CONCLUSIONSExpression of VEGF and CD34 was critically correlated with perioperative hemorrhage in gastric cancer patients. Co-expression of VEGF and CD34 could be an effective indicator for evaluating the risk of perioperative bleeding in gastric cancer patients.
