Objective To investigate the feasibility, safety and short-term efficacy of endoscopic implantation of 5-FU Slow-release Particles for advanced gastroenteric tumor. Methods During the endoscopy procedure,slow-releasing 5-FU agents were implanted densely into the tumors and infiltrated area. Forty-five to sixty pieces of agents ( each piece equivalent to 1.67 mg 5-FU)were injected, which containing an average dose of 100 mg 5-FU. Results A total of 13 advanced gastric cancer patients were enrolled into this study. Significant effects were observed in 3 patients and good effects in 8 patients, but 2 cases with no effects. The total effective rate was 84.62%. The endoscopy examination showed that the size of tumors reduced in various degree at 1 - 2months after the implantation. No hemorrhage or perforation was observed. Parameters of hepatorenal function and routine blood test were stable after implantation. Conclusion Endoscopic implantation of 5-FU Slow-release Particles can relieve the symptoms of patients and limit tumor growth in advanced gastroenteric tumor with no marrow and hepatorenal functional impair.

OBJECTIVETo observe the therapeutic effect of moxibustion on AIDS patients of spleen-kidney yang-deficiency.

METHODSSixty-six cases of AIDS were divided into a treatment group and a control group, 33 cases in each group. All of the patients were treated with HAART, with moxibustion at Tianshu (ST 25), Shenque (CV 8), Zhongwan (CV 12), Guanyuan (CV 4) added in the treatment group for 3 months. Clinical symptoms and cell immunity were recorded before and after treatment.

RESULTSAfter treatment, the effective rate was 90.9% in the treatment group, which was better than 66.7% in the control group (P < 0.05). The improvement of the score for clinical symptoms in the treatment group was superior to that in the control group (P < 0.01). After treatment, the CD4 lymphocyte counts increased in the two groups, with no significant difference between the two groups (P > 0.05). Additionally, increase of total lymphocyte count in the treatment group was superior to that in the control group (P < 0.05).

CONCLUSIONMoxibustion can increase the therapeutic effect of HAART on AIDS patients and increase the total lymphocyte count.

OBJECTIVETo constitute a model of B immunoblastic lymphomas in the Hu-PBL-SCID mice.

METHODSThe SCID mice were reconstituted by intraperitoneal injection (i.p.) of 5 x 10(7) human lymphocytes from Epstein-Barr virus (EBV) seronegative individuals. After one week, the SCID mice were inoculated with EBV by i.p. injection, and subjected to the investigation of whether there was any tumor in the abdomen of such SCID mice four weeks later. The characteristics of the found tumor was observed by the methods of Hematoxylin-eosin (HE) stain, immunohistochemical staining and polymerase chain reaction (PCR).

RESULTSCompared with the control groups, all the EBV-infected Hu-PBL-SCID mice had abdominal solid tumors [(32 +/- 12.5) mm3] developed, often located in the liver. HE staining and immunohistochemical staining showed the tumors were human B cell lymphomas. EBV DNA could be detected in the tumors by the PCR.

CONCLUSIONSThe model of B immunoblastic lymphomas in the Hu-PBL-SCID mice is successfully constituted, and may well be useful to the human tumor immunological study.

OBJECTIVETo investigate whether Candida albicans-native phospholipomannan (PLM) induce an inflammation response through Toll-like receptor(TLRé2 in human acute monocytic leukemia cell line (THP-1) cells.

METHODSHuman THP-1 monocytes were challenged with PLM in vitro. The mRNA expressions of TLR2, TLR4, proinflammatory cytokine [interleukin(IL)-6], and chemokine (IL-8) were assayed by real time reverse transcription polymerase chain reaction. The secretions of IL-6 and IL-8 were measured by enzyme-linked immunosorbent assay. The expression of TLR2 was analyzed with Western blot.

RESULTSPLM increased the mRNA expressions and secretions of proinflammatory cytokines (IL-6) and chemokines (IL-8) in THP-1 cells (all P=0.0000). PLM up-regulated the mRNA and protein levels of TLR2 (P=0.0000), whereas the mRNA level of TLR4 was not altered. PLM hydrolyzed with β-D-mannoside manno hydrolase failed to induce gene and protein expressions of TLR2, IL-6, and IL-8. Anti-TLRS-neutralizing antibody blocked the PLM-induced secretions of IL-6 and IL-8 in THP-1 cells (P = 0.0003, P = 0.0010).

CONCLUSIONCanidada albicans-native PLM may contribute to the inflammatory responses during Candida infection in a TLR2-dependent manner.

OBJECTIVETo explore the association between polymorphism in the ACE I/D gene and blood pressure-lowering response to hydrochlorothiazide (HCTZ) in 829 patients.

METHODSHCTZ 12.5 mg was taken once a day for six weeks. The blood pressure reduction and ratio reaching target blood pressure were compared in different ACE genotype groups.

RESULTSThe reduction in SBP of patients carrying DD was greater than that in other groups carrying II or ID (12.2 mmHg versus 5.4 mmHg, 12.2 mmHg versus 4.4 mmHg, respectively, P<0.05). The reduction in MAP of patients carrying DD was also greater than that in other groups carrying II or ID (6.9 mmHg versus 3.9 mmHg, 6.9 mmHg versus 3.6 mmHg, respectively, P<0.05). The ratio reaching target blood pressure in DD groups was significantly higher than that in II or ID groups (P<0.05). The pre-treatment SBP, DD genotype, aldosterone levels entered the multi-linear regression model significantly and might affect the reduction of SBP. The pre-treatment DBP, aldosterone levels, DD genotype entered the multi-linear regression model significantly and might affect the reduction of DBP. The pre-treatment MAP, DD genotype, aldosterone levels entered the multi-linear regression model significantly and might affect the reduction of MAP.

CONCLUSIONACE genotyping is associated with blood pressure-lowering response to HCTZ. Specific genotypes might be associated with the response to specific antihypertensive treatment.

Objective To initially establish an occupational well-being questionnaire for Chinese clinical nursing staffs.Methods The draft questionnaire,including open-ended questions and semi-structured interview,was established according to literature review and revised after expert′s consultation and pilot survey. Then,the questionnaire was tested by 460 nurses who randomly selected from a Class Ⅲ Grade Ⅰ hospital in Wuhan province from September 201 4 to June 201 5.The reliability and validity of the questionnaire were examined by exploratory factor principal component analysis,confirmatory factor analysis of maximum likelihood estimation method,and the Cronbach′s αanalysis.Results The questionnaire contained 1 9 items belonging to 5 dimensions that included welfare,value,interpersonal relationship,leaders and characteristics.The Cronbach′sαcoefficient for the questionnaire and each dimensions were 0.91 4 and 0.753-0.862.The correlation coefficients between each items and the total score as well as its related dimension were 0.487-0.729 and 0.709-0.883.The accumulative contribution rate of the five factors was 71 .1 05%.Conclusions The nurses′occupational well-being questionnaire is a reliable and valid instrument to assess the occupational well-being for clinical nursing staffs.

BACKGROUNDAnnexin A7 (synexin, ANXA7) is a member of annexins, which plays an essential role in the regulation of calcium homeostasis. Considerable evidence shows that the pathogenetic mechanism of acquired epilepsy (AE) has been related to the imbalance of calcium homeostasis. The aim of this study was to investigate ANXA7 expression and cellular localization in the cortex and hippocampus in the rat lithium-pilocarpine model of AE.

METHODSTotally 81 adult healthy male Wistar rats were randomly divided into control group (n = 9) and experimental group (n = 72), the experimental group contained eight subgroups according to sacrifice time (n = 9) (6-hour, 24-hour, 48-hour, 72-hour, 7-day, 15-day, 1-month, and 2-month). In the experimental group, rats were intraperitoneally injected by lithium-pilocarpine to induce AE model. We examined the expression and localization of ANXA7 via immunohistochemistry, double-label immunofluorescence with the use of neuron specific enolase (NSE) antibody, glial fibrillary acidic protein (GFAP) antibody and propidium iodide (PI), respectively. The data of optical density value were analyzed by analysis of variance.

RESULTSANXA7 expression increased significantly in the experimental groups especially in the acute period (6 hours, 24 hours, and 48 hours after the onset of seizure) using immunohistochemistry. Double-label immunofluorescence and confocal microscopy disclosed that ANXA7 localized in the neurons but not in astrocytes and did not localize in the nucleus, which were performed with anti-NSE, anti-GFAP and PI respectively.

CONCLUSIONANXA7 may play a potential role in the pathogenetic mechanisms of the rat lithium-pilocarpine model of AE.

BACKGROUNDBudd-Chiari syndrome (BCS) is a posthepatic portal hypertension caused by the obstruction of the lumen of the hepatic veins or the proximal inferior vena cava (IVC). This study aimed to evaluate the clinical experience of interventional therapy for Budd-Chiari syndrome.

METHODSIVC venography was carried out first, the obliteration or stenosis in the IVC was opened or dilated with the hard guided wire or Rups100 puncture needle and balloon, then a stent was routinely implanted for the type of obliteration or stenosis.

RESULTSThe procedure was successful in 821 out of 903 cases including IVC intervention in 760 cases, and hepatic vein intervention in 61 cases. An IVC stent was used in 517 cases and hepatic vein stent in 19 cases. There were no pulmonary embolisms, but acute renal failure occurred in eight cases, hepatic coma in two cases and acute heart failure in 43 cases. Two patients died in this group and five cases were complicated with acute IVC thrombosis. Follow up of 7 to 124 months was made in 679 cases with recurrence found in 59 cases.

CONCLUSIONSInterventional therapy is safe and effective with a fast recovery for most types of BCS. It is gradually becoming the first therapeutic choice.
