Objective To observe the effect of liver disease special-purpose enteral nutrition preparation on protein metabolism and liver function in children with liver injury.Methods Sixty cases of severe ill with liver injury in hospital,with mean age of (7.8?6.3) years old.All patients were randomly divided into experimental group (n=30) and control group(n=30).The experimental group was treated by adding the liver disease special-purpose enteral nutrition preparation homogenized diet and control group was treated by adding entire protein entire nutrition type enteral nutrition preparation.All patients in both 2 groups were nasally fed with intestinal nutrition,which contained 418-628 kJ/(kg?d).One day before nutritional support and 14 days after nutritional support,the liver function,total serum protein,albumin,hemoglobin were recorded.SPSS 11.5 software was used to analyze the data.Results The baseline indicators were similar before nutritional supports.Fourteen days after nutritional support,alanine aminotransferase(ALT) and aspartate aminotransferase(AST) were all significantly lower in experimental group than in control group(Pa

Objective To analyze comprehensively the monitoring data of iodized salt in Zhangjiakou city during 2001 to 2009, and to provide basic information for working out control strategies of the iodine deficiency disorders. Methods According to the iodized salt monitoring requirements in National Iodine Deficiency Disorders Monitoring Program of Ministry of Health, a batch of nine salt samples were taken from each processing (wholesale)company of each county or district of the seventeen counties(districts) of Zhangjiakou once a month. Two townships (towns, street offices) were selected by their location of east, south, west and north in each county(district), and a township in central area each year. Four villages(neighborhoods) were selected in each township(town, street office),and eight household salt samples were collected in each village(neighborhood), and quantitatively determined by direct titration of iodine. Results Iodized salt processing(wholesale) : during 2001 to 2009, a total of 1728 batches was monitored, 1689 batch qualified, batch qualification rate 97.74%;15552 salt samples were tested, 15 357 qualified, iodized salt qualification rate 98.75 %. Household salt levels : 5297 villages (neighborhoods) of 1305 townships(towns, street offices) were monitored, 44 316 salt samples were collected, 43 274 qualified, iodized salt qualification rate 98.04%(43 274/44 141 ), iodized salt coverage rate 99.61%(44 141/44 316), qualified iodized salt consumption rate 97.65%(43 274/44 316). Rate of non-iodized salt was 0.40%(260/44 316), and salt median iodine was 30.02 mg/kg. Conclusions The iodized salt quality indicators are within the state-controlled range in Zhangjiakou city for nine years which remaines at relatively stable levels with a smaller range of annual fluctuations.Detection of non-iodized salt over the years has become the main factors affecting the effectiveness of the prevention and control measures.We should increase monitoring,supervision,and universal health education,and prevent the spread of non-iodized salt.

OBJECTIVETo explore the potential effect of Guizhi plus Gegen Decoction (GGD) in improving learning and memory of lipopolysaccharides (LPS) induced neuroinflammatory mice and its possible mechanisms.

METHODSTotally 63 male ICR mice were randomly divided into 5 groups, i.e., the normal control (n = 13), the model group (n = 13), the low dose GGD group (n = 10), the high dose GGD group (n = 14), and the positive control group (n = 13). Mice were intraperitoneally injected with LPS (0.33 mg/kg) to induce Alzheimer's disease (AD) model. Mice in the high and the low dose GGD groups were administered with 12 g/kg or 6 g/kg by gastrogavage for 4 successive weeks. Mice in the control group were intraperitoneally injected with minocycline (50 mg/kg) for 3 days. By the end of treatment LPS were injected 4 h before behavior test each day, and then behavior test was conducted in mice of each group. Effect of GGD on learning and memory of AD mice was observed by using open field test, novel object recognition task, and Morris water maze.

RESULTSOpen field test showed there was no statistical difference in the movement time and the movement distance among all groups (P > 0.05), suggesting that LPS and GGD had no effect on locomotor activities of mice. In novel object recognition test, AD mice spent significantly shorter time to explore novel object after they were induced by LPS (P < 0.05), while for AD mice in the low and high dose GGD groups, their capacities for exploration and memory were significantly improved (P < 0. 05, P < 0.01). Results of Morris water maze showed that AD mice exhibited increased escape latency (P < 0.05) and spent much less time in swimming across the original platform (both P < 0.05). However, AD mice in the low and high dose GGD groups had obvious shortened latency and increased time percentage for swimming (P < 0.05, P < 0.01).

CONCLUSIONGGD possessed certain improvement in learning and memory disorder of LPS induced AD mice.

OBJECTIVETo investigate the startup detail of circulation dysfunction and its role in the progress of delayed neuropsychologic sequelae (DNS) after carbon monoxide (CO) poisoning with comparison with the model of ischemia-reperfusion.

METHODSThe ischemia-reperfusion rat model was established by Pulsinelli-Brierley method, and the CO poisoning rats model by i.p. injected with CO repeatedly respectively, and the rats were identified with DNS following the experiment of pathology and the ethnology.

RESULTSThe whole blood viscosity, plasma viscosity, hematocrit and fibrinogen increased significantly immediately after reperfusion, and recovered gradually with the ischemia-reperfusion rat model. The whole blood viscosity decreased significantly immediately after CO treated i.p. Especially at low shear rate, the hematocrit also declined remarkably in the early stage after CO treatment. But 1day later, these parameters turned to the trend of the ischemia-reperfusion rats. There was a prominent elevation of both indexes until the 14th day following CO injection i.p.

CONCLUSIONThere are significantly sustained hyper-coagulation and hyper-viscosity with circulation in rats after CO poisoning compared with ischemia-reperfusion model during the period of DNS, which might contribute to increase cerebral circulation resistance, blocked blood flow, and deteriorate hypoxemia in progression of DNS.

OBJECTIVETo analyze the pathological type and clinical features of patients with lymphoma cell leukemia (LML).

METHODSAccording to the 2008 WHO classification of tumors of hematopoietic and lymphoid tissue, the pathological type and clinical features of 127 LML cases were analyzed retrospectively.

RESULTSThere were 15 kinds of NHL developed LML. The incidence in frequent order of them was B-lymphoblastic lymphoma, CLL/small lymphocytic lymphoma (SLL) and T-lymphoblastic lymphoma. The LML of T and B cell subtypes were 45 and 74, respectively. There was a significant difference in overall survival between T-LML and B-LML (P < 0.01). Eighty one patients presented LML at the same time of the NHL diagnosis and 46 during the course (1 - 88 months) of disease. Primary nodal and extranodal NHLs developed LML were 96 and 31 cases, respectively. The clinical manifestations of LBL and SLL patients differed from that of ALL and CLL patients.

CONCLUSIONLML is not a rare manifestation of NHL. Pathological types of NHL developed LML are 15 kinds in our patients. The clinical features of LML patients are somewhat special, especially for primary extranodal LML patients.

OBJECTIVETo investigate the expression of phosphatase of regeneration liver-3(PRL-3) protein and its relationship with tumor invasion and metastasis in human colorectal carcinoma,and elucidate prognostic value.

METHODSImmunohistochemistry method was applied to detect the PRL-3 expression in the primary tumor specimens and paired paratumor normal tissues from 46 colorectal carcinoma patients, the adenoma tissues from 6 patients with colorectal adenoma, all the metastatic lymph nodes from 29 cases and the metastatic liver lesions from 6 cases. The relationship between PRL-3 expression and clinicopathologic parameters was analyzed and a survival curve was achieved according to Kaplan-Meier method.

RESULTSNo or weak PRL-3 protein expression was detected in normal colorectal mucosa and colorectal adenoma. In colorectal carcinoma tissues, PRL-3 expression was confirmed in 26 of 46 cases (56.5%) of primary colorectal carcinomas (with lymph node metastasis 63.0%, without lymph node metastasis 37.0%, P=0.001), 26 of 29 (89.7%) lymph node metastases, and 5 of 6 liver metastases. The expression of PRL-3 was assembled in the cytoplasm of carcinoma cells and more intensively on the cell membrane.Analysis of the relationship between PRL-3 expression and the clinicopathologic features showed that PRL-3 expression was closely associated with tumor stage (P=0.019), lymph node metastasis (P=0.026), but no relationship with age, sex, tumor size, degree of differentiation was founded (P<0.05). The mean follow-up time was 41.4 months and results showed that patients with positive expression of PRL-3 had a significantly poorer prognosis than those with negative PRL-3 expression group(P=0.032).

CONCLUSIONSPRL-3 protein plays a novel role in tumor progression and metastasis of colorectal carcinoma. PRL-3 can be expected to be a potential predictive biomarker for identifying the prognosis in colorectal carcinoma patients.

OBJECTIVETo investigate the effect of omega-3 polyunsaturated fatty acids(omega-3PUFAs) on the apoptosis of human gastric cancer cell line SGC-7901 and to explore the potential mechanisms.

METHODSCells were treated with eicosapentaenoic acid (20:5 omega-3,EPA) or docosahexaenoic acid (22:6 omega-3, DHA) at concentrations of 10, 20 and 40 microg/ml. Cell growth and apoptosis were analyzed with MTT assay, cell morphology, DNA electrophoresis and flow cytometry. Mitochondrial membrane potential ( triangle right psi mt) was measured by fluorescent probe rhodamine 123. The distribution of cytochrome C in mitochondria and cytosol was determined by enzyme-linked immunoadsorbent assay. The composition of mitochondrial membrane phospholipid(MMP)was examined by gas chromatography.

RESULTSBoth EPA and DHA markedly inhibited the SGC-7901 cell growth and induced apoptosis in a time- and dose-dependent manner. After incubation of the cells with 40 microg/ml EPA or DHA for 24 hours, the level of Deltapsimt siginificantly decreased (P<0.001), and cytochrome C largely released into cytosol from mitochondria. The proportions of EPA and DHA in MMP rapidly elevated while that of arachidonic acid sharply decreased.

CONCLUSIONSomega-3PUFAs inhibit the growth of gastric cancer cells through promoting apoptosis. Compositional and functional alterations in mitochondrial membrane may be an important initiator of apoptosis induced by omega-3PUFAs.
