Objective To investigate the impact of accountable and kindred-like nursing and the practice of quality care.Methods 100 primiparas who gave birth three months before the accountable and kindred-like nursing were selected as the control group,while 100 primiparas who gave birth three months after accountable and kindred-like nursing were selected as the observation group.Tow groups' understanding of health education knowledge and skills,satisfaction with nursing when discharged,nomination rate of the most satisfactory nurse and compliance behavior after discharged were compared.Results In the observation group,62 cases had fully understood,28 had basically understood and 10 had not understood the health education knowledge when discharged,while in the control group the numbers were respectively 30,56 and 14.In the observation group,75 cases had fully understood,19 had basically understood and 6 had not understood the health education skills when discharged,while in the control group the numbers were respectively 28,58 and 14.The understanding of health education knowledge and skills were much better in the observation group than in the control group,and the differences were statistically significant (x2 =21.13,44.40,respectively; P ＜0.05).After being discharged,the compliance behaviors including pure breastfeeding,newborn massage and baby swimming of the observation group were also better than the control group (49 vs 27,58 vs 27,47 vs 18,respectively),and the differences were statistically significant (x2 =9.93,20.14,19.16,respectively; P ＜0.05).There were no significant differences in infant buttock nursing between two groups (P ＞ 0.05).The satisfaction of nursing and nomination rate of the most satisfactory nurse were also much higher in the observation group (99 vs 93,82 vs 53,respectively),and the differences were statistically significant (x2 =10.86,19.17,respectively ;P ＜ 0.05).Conclusions Accountable and kindred-like nursing can enhance the effect of health education,compliance behaviors,so as to improve the satisfaction degree of puerperants and their families with nursing service.

OBJECTIVETo investigate the therapeutic effect of Corbrin shugan capsule for treatment of alcoholic hepatic fibrosis in rats.

METHODSThe rat model of alcoholic hepatic fibrosis was induced by intragastric administration of alcohol repeatedly. The serum procollagen III (PC III), laminin (LN) and tissue inhibitors of metalloproteinase-1 (TIMP-1) levels were measured with ELISA, and the content of hydroxyproline (Hyp) in liver tissue were determined with colorimetric method. Collagen deposition in liver tissue was observed with Masson's staining, and the fibrosis area was measured with digital medical image analysis system (Motic Med 6.0).

RESULTSCompared with the model control group, the serum TIMP-1 and LN levels and hepatic fibrosis area in liver tissue significantly decreased in Corbrin shugan capsule groups with doses of 0.09,0.27 and 0.45 g*kg(-1), and the serum PC III and the Hyp contents in liver tissue also decreased of Corbrin shugan capsule groups with doses of 0.27 and 0.45g*kg(-1).

CONCLUSIONCorbrin shugan capsule can decrease serum PC III, TIMP-1 and LN levels and Hyp levels in liver tissue and hepatic fibrosis area in rats, indicating it may have therapeutic effect on alcoholic hepatic fibrosis.

Objective: To investigate the function and mechanism of phospholipase Cγ1 (PLCγ1) in cell-matrix adhesion in colorectal cancer. Methods: Highly metastatic colorectal cancer cell line LoVo and lowly metastatic colorectal cancer cell line SW480 were subjected to cell-matrix adhesion assay. U73122 (a specific inhibitor of PLC) and pyrrolidine dithiocarbamate (PDTC) (an inhibitor of NF-κB) were used to study the effect of PLCγ1 and NF-κB on cell-matrix adhesion. Furthermore, Western blot and gel electrophoresis mobility shift assay (EMSA) were performed to detect the mechanism of PLCγ1 in colorectal cancer cell adhesion to matrix. Results: Inhibition of PLCγ1 or NF-κB resulted in reduction of cell-matrix adhesion in a dose-dependent manner in LoVo cells(P<0.05), but had no marked effect on SW480 cells. Western blot analysis showed that epidermal growth factor (EGF) stimulated the phosphorylation of PLCγ1 in LoVo. The results of EMSA indicated that inhibition of PLCγ1 signaling pathway also down-regulated the activity of NF-κB while EGF reversed the function. Conclusion:These data suggest that PLCγ1 plays a pivotal role in the EGF-induced cell-matrix adhesion of highly metastatic colorectal cancer cells and that NF-κB is also functional in this signaling pathway.

BACKGROUND: This study aimed to investigate the epidemiological and clinical characteristics of patients with heat-related il ness, and guide the prevention, diagnosis and treatment of heat-related il ness. METHODS: From June 2013 to August 2013, seventy patients with heat-related illness were treated at Jinshan Hospital of Fudan University, and their epidemiological characteristics, laboratory results, treatment and prognosis were retrospectively analyzed. RESULTS: In the 70 patients, 18 patients suffered from heat stroke and 52 patients from non-heat stroke. When the environmnent temperature was above 35 °C, the body temperature of the patients began to increase markedly. The patients with heat stroke were significantly older than those with non-heat stroke (P<0.05). The body temperature, heart rate, blood glucose, blood lactate dehydrogenase and blood creatine kinase in the patients with heat stroke were higher than those in the patients with non-heat stroke (P<0.05). Blood lactate dehydrogenase and blood creatine kinase were positively correlated with body temperature (r=0.801). CONCLUSION: When the environmental temperature goes above 35 °C, heat-related illness should be prevented, especially in the elderly. The body temperature, heart rate, blood glucose, blood lactate dehydrogenase and blood creatine kinase in patients with heat stroke are higher than those in patients with non-heat stroke. Blood lactate dehydrogenase and blood creatine kinase are positively correlated with body temperature, but their relationship with heat-related illness awaits further study.

OBJECTIVEThis study explored the dynamic expression of the E3 ubiquitin-protein ligase gene, Arkadia, in response to carbon tetrachloride (CCl4)-induced liver fibrosis in a mouse model and investigated the differential expression that occurs following treatment with the anti-fibrotic bone morphogenetic protein-7 (BMP-7).

METHODSThirty healthy male imprinting control region (ICR) mice were randomly assigned to three groups: normal (control; n = 6), CCl4-induced model group (model; n = 18), and CCl4-induced model with BMP-7 treatment group (treatment; n = 6). The model group was further divided into three subgroups (n = 6 each) for analysis at 4, 8 and 12 weeks after fibrosis induction. Liver fibrosis was induced by hypodermic injections of 60% CCl4 /peanut oil (5 mL/kg) to the hind legs of mice two-times per week in alternating legs for a period of 12 weeks. At week 9, the treatment group of CCl4-induced mice were given an intraperitoneal injection of BMP-7 (300 pg/g) simultaneously with that day's hypodermic injection of 60% CCl4 /peanut oil, and then every other day for a period of four weeks. The pathological changes in liver tissues were observed after staining with hematoxylin-eosin (HE) and Masson's trichrome. Messenger RNA (mRNA) and protein expression of Arkadia in liver were evaluated using reverse transcription-polymerase chain reaction and immunohistochemistry and Western blotting, respectively.

RESULTSMouse models of liver fibrosis were successfully established by CCl4 exposure. Arkadia, Smad7 and TGF-beta1 mRNA levels were up-regulated in the model group in a time-dependent manner (vs. control group), and BMP-7 treatment led to significant down-regulation of the CCl4-induced expression of the three genes (vs. control group: F = 812.80, 451.46, and 998.96, respectively; P less than 0.01). At week 12, the mRNA levels of Arkadia, Smad7, and TGF-b1 were significantly lower in the BMP-7 treatment group than in the model group (t = 12.108, 18.737, and 16.364, respectively; P less than 0.01). Arkadia, Smad7, and TGF-b1 protein staining was weak in the portal area of control liver tissue. In contrast, the model group showed significantly stronger staining for all three proteins in the portal area and in the cytoplasm of liver cells. The staining of Arkadia, Smad7, and TGF-b1 proteins was significantly lower in the treatment group (vs. control group: F = 8.399, 609.690, and 900.561, respectively; P < 0.01). At week 12, the protein levels of Arkadia, Smad7, and TGF-b1 were significantly lower in the treatment group than in the model group (t = 23.438, 11.667, and 42.889, respectively; P < 0.01).

CONCLUSIONArkadia expression gradually increased along with the development of liver fibrosis but was suppressed by treatment with the anti-fibrotic factor, BMP-7.

OBJECTIVETo investigate magnetic resonance imaging (MRI) characteristics of ovarian carcinosarcoma and the diagnostic value of MRI.

METHODSThe MRI features of ovarian carcinosarcoma and clinical data of 5 patients with ovarian carcinosarcoma were reviewed. All the lesions were confirmed by surgery and pathological examination.

RESULTSMRI of ovarian carcinosarcoma in the 5 cases all showed large tumor mass and heterogeneous high-intensity on T2-weighted images and low-intensity on T1-weighted images, with laminar or stripe-like enhancement. Hemorrhage and necrosis were also displayed in some lesions. In two cases, the tumors invaded the greater omentum, sigmoid colon and the body of the uterus, with regional lymph node involvement. Pelvic effusion was observed in all the cases with pelvic hematocele in 1 case.

CONCLUSIONMRI is useful in the detection and staging of ovarian carcinosarcoma.

OBJECTIVETo investigate the expression variation and significance of Skp2 and p27(kip1) during the proliferation of lymphoma cell line Jurkat cells.

METHODSThe binding of p27(kip1) and Skp2 in Jurkat cells were detected by immunoprecipitation. Jurkat cells were treated with serum starvation and release synchronization. The expression variation and subcellular localization of p27(kip1) and Skp2 were detected by subcellular fractionation, Western blot and double immunofluorescence labelling.

RESULTSThe results of immunoprecipitation suggested that p27(kip1) and Skp2 could bind each other in Jurkat cells. During the proliferation of Jurkat cells, the protein expression of p27(kip1) decreased and intranuclear p27(kip1) decreased significantly, while the Skp2 protein increased and cytoplasmic Skp2 increased significantly.

CONCLUSIONDuring the proliferation of Jurkat cells, the increased cytoplasmic synthesis of Skp2 may speed up p27(kip1) degradation via the ubiquitin-proteasome pathway, then intranuclear p27(kip1) decreases significantly, leading to an increased cell cycling activity.

OBJECTIVEThe objective of this study was to observe the interventional effect of cod liver oil supplementation on re-vaccination to hepatitis B virus (HBV) among infants and young children.

METHODSAll 7-36 months old infants and young children, who had been vaccinated with obligatory HBV vaccines routinely by the national technical and administrative procedures for HBV vaccination on children of China, were convened among villages in Linyi, Shandong province, from October 2008 to March 2009. After detection of serum anti-HBV, one hundred children with lower serum anti-HBV were picked out for the randomized, double blinded, placebo controlled vitamin A supplementation study. The children in the intervention group (50 subjects) took 0.5 g condensed cod liver oil (containing 25 000 IU vitamin A and 2500 IU vitamin D(2)) every 15 days for six times. The children in the control group (50 subjects) were given corn oil with same volume. All children were re-vaccinated at the 30th and the 60th day of the experiment. The serum samples were collected from each child at the 90th day of the experiment. Retinol concentration in serum samples was analyzed with HPLC method before and after the intervention. The levels of serum anti-HBs were detected by the electro-chemi-luminescence immunoassay (ECLIA).

RESULTSTotal 74 children finished the supplemental experiment and blood collection, 37 subjects in each group, respectively. After intervention, the serum retinol level in the experimental and control group were (404.1 ± 123.1) and (240.8 ± 92.8) µg/L (t = 6.441, P < 0.01), respectively. The serum anti-HBs levels in the experimental and control group were (2737.2 ± 2492.6) and (1199.7 ± 2141.6) U/L (t = 2.846, P < 0.01), respectively. The rate of weak or no-answer case in experimental and control groups was 0.00% (0/37) and 10.81% (4/37) (χ(2) = 4.229, P = 0.040), respectively.

CONCLUSIONThe results showed that vitamin A supplementation might enhance the re-vaccination reaction against HB vaccine in infants and young children.

BACKGROUNDIt was still rare for the quantitative magnetic resonance imaging (MRI) research of regional changes in hippocampus sclerosis (HS) in Chinese patients with epilepsy. This study aimed to study the hippocampal volumes (HVs) with quantitative MRI measurement in Chinese patients with epilepsy.

METHODSForty-six Chinese patients with epilepsy (intractable epilepsy (IE), n = 21; non-intractable epilepsy (NIE), n = 25) and 25 normal controls were collected between July 2007 and March 2008. All of the subjects underwent a 3T high-resolution MRI with oblique coronal thin sections oriented perpendicular to the hippocampal long axis. Hippocampal structures were assessed by visual detection, and HVs were quantitatively studied with a Picture Archiving and Communication System (PACS).

RESULTSOur study suggested that there was no significant difference in gender (P > 0.05) while the right hippocampal head volume (HHV), hippocampal body volume (HBV), and the whole hippocampal volume (HCV) were greater than the left one (P < 0.05), but no significant difference was found in bilateral hippocampal tail volume (HTV) (P > 0.05) in normal controls. That unilateral/diffuse (64%/21%) and bilateral/focal (86%/20%) hippocampal atrophy (HA) were significant in IE and NIE patients, respectively. Anterior hippocampus, especially HHV (26% in IE and 20% in NIE) and HBV (29% in IE and 12% in NIE), had more significant atrophy than the HTV (5% in IE and 0% in NIE) in patients with epilepsy.

CONCLUSIONBy assessing the volumes of the regional hippocampus with 3T MRI, we could better define the range and distribution of HS, since regional or subtle changes in HVs could be detected earlier with 3T MRI.

Interleukin-2 (IL-2) therapy often results in potentially life-threatening side effects including hypotension. However, the mechanism has not been completely elucidated. In order to determine whether IL-2 modifies vascular tone, we investigated the effect of IL-2 on rat thoracic aorta rings and the underlying mechanisms. Effects of IL-2 on the contraction of high KCl and phenylephrine (PE) preconstricted rat thoracic aorta with or without endothelium were determined by organ bath technique. To explore the mechanism, nitric oxide synthase inhibitor L-N(G)-nitroarginine methyl ester (L-NAME), guanylyl cyclase inhibitor methylene blue, and cyclooxygenase inhibitor indomethacin were used. IL-2 (10-1000 U/ml) caused concentration-dependent relaxation of aorta rings preconstricted with PE (10 micromol/L) in endothelium-intact rings, but had no effect on KCl (120 mmol/L) preconstricted rings. Removal of the endothelium, or pretreatment with L-NAME (0.1 mmol/L) or methylene blue (10 micromol/L) or indomethacin (10 micromol/L), inhibited the relaxation of IL-2. The results indicate that the relaxation by IL-2 in rat aorta ring is endothelium-dependent and is possibly mediated by the NO-guanylyl cyclase pathway and cyclooxygenase-dependent pathway.
