Objective To investigate transitional care needs of the patients with gastric carcinoma before discharging, and improve their quality of life. Methods Through questionnaire and convenience sampling, 78 gastric carcinoma patients were recruited from a cancer hospital in Beijing. A self-made questionnaire was used to investigate the transitional care needs of the patients before discharging. Results 94.9% (74/78) of patients needed transitional care. 92.3% (72/78) of patients were willing to receive transitional care either from hospital they were discharged from or community medical institutions nearby with the guidance of the hospital. The most prevalent demands of the gastric cancer patients included food、return visit、the follow-up treatment、wound and defecation. The rates were 100.0%(78/78), 100.0% (78/78), 100.0% (78/78), 92.3% (72/78), 85.9% (67/78). Conclusions Most of the gastric carcinoma patients highly demanded transitional care. We should strengthen the management of patients after discharge, so as to improve their quality of life.

At present the most common colorimetry for the activity determination of the peroxidase ( POD) is based on the detection of the absorbance of product at 470 nm in a reaction system of the H2 O2/POD/guaiacol ( GA) , but the shortcoming of the method is that the formed product is not stable and there is the serious adsorption phenomenon on the cell. To solve this problem, a new method was established for accurate determination of POD activity based on the fluorescent feature of GA. By using standard solutions of horseradish peroxidase as the test samples and under these optimum conditions such as 0. 5 mmol/L of GA, 0. 5 mmol/L of H2 O2 , pH 6, 0. 05 mol/L of phosphate buffer solution and the reaction temperature of 20℃, the sample volume was only consumed 20 microlitre at a time, the linear response range was 500-60000 U/L ( r=0 . 9993 ) , the detection limit was 385 U/L and relative standard deviation was ≤2 . 4% ( n=11 ) . The comparisons for the determination results of the POD activity in the white radish’s extraction solutions were conducted among our method (9714±132 U/L) and the colorimetric method (9926±352 U/L) as well as the recirculating-catalytic flow analysis ( 9608±456 U/L ) . The results showed that the mutual consistency is better.

BACKGROUND: Family factor is the main reason for children's psychological and behavioral problems. Seen from the view of systemic family theory, in any circumstances, children's behavioral problems reflect various interpersonal systemic networks among society, school, family, relatives and friends and the relationship of complicated interactions among individuals.Family therapy is an important way to cure children's behavioral problems.OBJECTIVE: To observe whether systemic family rehabilitation is adequate for intervening in children's behavioral problems.DESIGN: Cluster sampling; Contrast observationSETTING: Department of Psychiatry, Kunming Medical College.PARTICIPANTS: A total of 276 students in grade four from Mingtong primary school of Kunming City were selected along with their parents from May 2004 to March 2005. A survey was conducted on students and their parents according to the principle of cluster sampling.METHODS: Self-rating family dynamics scale was used to investigate the characteristics of family dynamics of 276 students in grade four. Achenbach child behavior checklist for parents was adopted to investigate the situation of their children' s behaviors. 57 cases of children with behavioral problems were detected out, and took the families in which the whole family members voluntarily participated in the intervention as interventional group and the families in which any one of the family members did not want to participate in the intervention as abnormal control group. The students and their parents in interventional group were treated with 4-month systemic therapy. 4 months later, resent the above rating scales.MAIN OUTCOME MEASURES: Comparison of family dynamics and children's behaviors between interventional group and abnormal control group before and after intervention.RESULTS: After intervention, changes of family dynamics and children's behaviors in interventional group had taken place, which had statistical difference. The changes as follows: family atmosphere changed from "depressive and hostile" to "harmonious, pleasant, equal and exoteric"; the degree of individuation of family members changed from low level to high; disease concept changed from "regarding the patients as helpless victims" to "regarding them as helpful doers", which realize "softening of disease concept". The total scores of Achenbach child behavior checklist for parents decreased [The scores of questionnaire for fathers before and after intervention were (42.20±22.58) and (28.95±21.90) respectively, and scores of questionnaire for mothers before and after intervention were (50.95±14.60) and (36.40-±15.36) respectively, P ＜ 0.05]. There was no significant difference between the changes of children's behaviors assessed by fathers and mothers in abnormal control group [The scores of questionnaire for fathers before and after intervention were (38.32±17.30) and (37.57±16.45) respectively, and scores of questionnaire for mothers before and after intervention were (45.54±16.02) and (40.14±17.95) respectively, P ＞ 0.05].CONCLUSION: Using the idea and technique of systemic family therapy ,it is feasible and effective to intervene in children's behavioral problems by family therapy.

Objective To investigate the safety and accuracy of diagnosing alpha-thalassemia with extraembryonic coelomic cells. Methods Coelocentesis was performed before artificial abortion to collect extraembryonic coelmic fluid in 40 women with singleton pregnancy during 6-10 gestational weeks. The villi was gathered after suction. PCR technique was used to amplify alpha-thalassemia gene in both extraembryonic coelomic cells and villi and concordant rate of two different kinds of samples were compared. Results The genotypes of alpha-thalassemia were successfully amplified in 37 cases of coelomic cells and all were concordant with the results of villi. Conclusion Extraembryonic coelomic cells can be used in early prenatal diagnosis of alpha-thalassemia by PCR technique and is practicable.

Objective: To develop the Chinese version of the Neuropsychiatric Inventory Questionnaire (NPI-Q) and evaluate its reliability and validity. Methods: Three investigators assessed 10 dementia cases together with the NPI-Q to evaluate the inter-rater reliability. Eighty-six dementia cases and 30 healthy controls were assessed with the Behavioral Pathology in Alzheimer's Disease (BEHAVE-AD), the Brief Psychiatric Rating Scale (BPRS) and NPI-Q to evaluate the criterion validity. A subgroup of 30 dementia cases was tested with the NPI-Q again 24 h later to evaluate the test-retest reliability. Results: (1) Internal consistency. Cronbach's a coefficient of the severity subscale was 0.589, mean inter-item correlation coefficient of the severity subscale was 0.107. Cronbach's α coeffi-cient of the distress subscale was 0.612, and the mean inter-item correlation coefficient of the distress subscale was 0.114. (2) Inter-rater reliability. Intraclass correlation coefficient (ICC) of the severity subscale was 0.97, and ICC of the distress subscale was 0.94. (3) Test-retest reliability. The test-retest correlation coefficient of the severi-ty subscale was 0.89, and the test-retest correlation coefficient of the distress subscale was 0.86. (4) Criterion va-lidity. The severity subscale total score was correlated significantly with BEHAVE-AD (r=0.70, P <0.001) and BPRS(r=0.40, P<0.001) total score; the distress subscale total score was correlated significantly with the global ratings in part 2 of BEHAVE-AD (r=0.76, P<0.001) . (5) The severity subscale total score in demen-tia group was significantly higher than that in control group (median: 10 vs.1.5, P <0.001). The distress sub-scale total score in dementia group was significantly higher than that in control group (median: 10 vs 0; P< 0.001) . (6) Exploratory factor analysis identified 4 common factors, including psychosis, abnormal behavior,discontrol and affective symptoms, which explained 58.3% of total variance. All of the items loaded were between 0.596 and 0.803 on their conrresponding factor. Conclusion: The reliability and validity of the Chinese version of NPI-Q meet the psychometrics properties, and deserves to conduct further study in larger samples.

Objective To determine the prevalence of organ failure and its risk factors in patients with severe acute pancreatitis(SAP). Method A retrospective analysis was conducted in 186 patients, who were hospitalized in the intensive care unit of Jinzhong First People's Hospital with SAP between March 2000and October 2009. SAP patients met the diagnostic criteria of SAP set by Surgery Society of Chinese Medical Association in 2006. The variables included age, gender, etiology of SAP, the number of comorbidit, APACHE Ⅱ score, CECT pancreatic necrosis, CT Severity Index ( CTSI ), abdomen compartment syndrome (ACS) ,the number of organ failure and the number of death. The prevalence and mortality of organ failure were calculated. The above-mentioned variables were analyzed by unconditional multivariate logistic regression analysis to determine the independent risk factors for organ failure in SAP. Results Of 186 patients, 96had organ failure. In 96 patients with organ failure, 47 died. There was a significant association between the prevalence of organ failure and age, the number of comorbidit, APACHE Ⅱ score, CECT pancreatic necrosis, CTSI, ACS. An increase in age, the number of comorbidit, APACHE Ⅱ score, CECT pancreatic necrosis correlated with an increase in the number of organ failure. Age, the number of comorbidit, APACHE Ⅱ score,CECT pancreatic necrosis, CTSI and ACS went into the unconditional multivariate logistic regression equation. Conclusions Organ failure occurred in 51.6% of 186 patients with SAP. The mortality of SAP with organ failure is 49.0%. Age, the number of comorbidit, APACHE Ⅱ score, CECT pancreatic necrosis,CTSI and ACS are independent risk factors of organ failure.

The latest WHO classification of tumors is the most important standard for clinicpathologic diagnosis of pathologists in medical practice.We should study,grasp,and apply it to medical practice for need of patients and ourselves.

Objective To explore whether the polymorphism of human frizzled 3 (rs2241802 ,rs2323019,rs352203) is associated with schizophrenia in Yunnan Han population. Methods PCR-RELP was used to detect the polymorphism of human frizzled 3 (rs2241802 ,rs2323019, rs352203 ) in 153 patients and 100 controls. All patients were evaluated with positive and negative symptom scale(PANSS). Following a linkage disequilibrium test in the 3 loci ,association analysis was carried out between the polymorphism, including haplotype,and schizophrenia in all samples. Results No significant difference of genotype and allele frequency of the 3 loci were observed in 2 groups. There was no difference in genotype and allele frequency of rs2241802 ,rs2323019,rs352203 in Han samples (P＞0.05) . The polymorphisms of the 3 loci had been observed no difference in case-sibling control study of normal group. A-A-C haplotype and G-A-C haplotype were observed with a higher frequency in both samples (P＜0.05). There was no difference in patients and controls in PANSS scores (P ＞ 0.05 ). Conclusions There is no association between polymorphisms of human frizzled 3 ( rs2241802, rs2323019, rs352203 ) and schizophrenia in Han. A-A-C and G-A-C haplotype might possibly associate with schizophrenia in Yunnan Han population.
