OBJECTIVETo compare the efficacy of bicyclol tablets on patients infected with hepatitis B virus between genotype B and C.

METHODS70 patients with chronic viral hepatitis B were selected. The patients divide into two groups: HBV genotypes B (26 cases) and HBV genotypes C (other 44 cases). All patients received bicyclol tablets orally 150 mg daily (50mg, tid, po) for 24 weeks. The efficacy were observed after 12 weeks and 24 weeks.

RESULTSAfter treatment for 24 weeks, the serum aminotransferase were decreased obviously, and HBV DNA levels turn to be negative with 19.2 percent (genotype B group) and 15.9 percent (genotype C group), respectively. The difference was not statistically significant between HBV genotype B and C.

CONCLUSIONBicyclol not only has hepatoprotective activity but also inhibited virus replication in patients infected with HBV. The difference of the response to bicyclol therapy between HBV genotypes B and C was not statistically significant.

OBJECTIVETo construct a replication-defective recombinant adenovirus expressing the ORF2 (112-660aa) antigen of hepatitis E virus (HEV) and evaluate its immunization effect in BALB/c mice by mucosal inoculation.

METHODSThe HEV ORF2 gene encoding for 112-660aa was amplified from plasmid pUC-HEV and inserted into the transfer vector pTrack-CMV. The recombinant plasmid and adenoviral backbone plasmid pAdEasy-1 were co-transformed into E. coli strain BJ5183. Taking the advantage of the high efficient homologous recombination machinery presented in bacteria, the recombinant adenovirus backbone plasmid was generated in BJ5183, and then was transfected into 293 cells. Recombinant Adenoviruses were propagated in 293 cells with high titers. 8-week-old BALB/c mice were inoculated intraperitoneally and intranasally with 10(7) pfu recombinant adenovirus each on weeks 0, 3, 5, 7, 10.

RESULTSBoth groups of mice induced humoral IgG immune response with the highest titers 1:1,000 and 1:10,000 each. Only the group inoculated intranasally could induce mucosal IgA immune response.

CONCLUSIONSThe adenoviral recombinant can stimulate specific humoral and mucosal immune response in mice and is potentially to be used as a candidate vaccine for the treatment of HEV infection.

Objective To explore the status of cognition on hospice care of community health care providers in Changchun City so as to provide an effective reference for developing hospice care in community and relevant departments.Methods From January to March 2017,we extracted three districts(Chaoyang District,Luyuan District,Nanguan District of Changchun City)by convenience sampling and selected 260 eligible community health care providers from 10 community health service centers by chester sampling as respondents.The status of cognition on hospice care of community health care providers was investigated with the self-designed questionnaire.The SPSS 19.0 was used to data analysis.Results The score of knowledge,attitude and behavior on hospice care of community health care providers was(13.26±2.94),(138.29±13.16)and(20.89±3.42)respectively.Conclusions Community health care providers of Changchun City are with a positive attitude toward hospice care.At the same time,they do well in hospice care provided for the dying patients and their family members.However,their grasping state on knowledge of hospice care is weak due to lack systematic professional knowledge training in hospice care.We should strengthen knowledge education as well as training in hospice care for community health care providers and improve the whole cognition on hospice care of community health care providers.

The molecular pathogenesis of leukemia is poorly understood. Earlier studies have shown both Wilms' tumor 1 suppressor gene (WT1) and CML28 abnormally expressed in malignant diseases of the hematopoietic system and WT1 played an important role in leukemogenesis. However, the relationship between molecular CML28 and WT1 has not been reported. Here we described the use of small interfering RNA (siRNA) against WT1 and CML28 in leukemic cell line K562 to examine the interaction between CML28 and WT1. WT1 and CML28 gene expression in transfected K562 cells was detected by using RQ-PCR and Western blotting. K562 cells transfected with WT1-siRNA could greatly decrease both mRNA and protein expression levels of WT1 and CML28. In contrast, CML28-siRNA did not exert effect on WT1. Further, subcellular co-localization assay showed that the two proteins could co-localize in the cytoplasm of K562 cells, but WT1/CML28 complexes were not detected by using immunoprecipitation. It was suggested that there exists the relationship between CML28 and WT1. CML28 may be a downstream target molecule of WT1 and regulated by WT1, which will provide important clues for further study on the role of CML28 and WT1 in leukemic cells.

OBJECTIVETo explore the feasibility of a dual-energy computed tomographic angiography (DECTA) protocol using test-bolus injection with reduction of contrast material (CM) dose in second generation dual-source CT system.

METHODSTotally 57 consecutive patients underwent CT angiography scan covering the cervical and cerebral arteries. CT was performed with second generation dual-source CT system. The time to peak (T) using a test-bolus injection was calculated. The patients were divided into three groups (A, B, and C) with different CM doses (40, 45, and 50 ml) and different delay time points [ (T+1) , (T+1) , and (T+2) s] . All the patients were followed by a 48 ml saline flush. Arterial enhancements were quantified by measuring attenuation values of the aortic arch, bifurcation of common carotid artery, contralateral internal jugular vein of the CM injection, superior vein cava, proximal middle cerebral artery, basilar artery, and straight sinus on source images. Visualizations of intracranial artery and ipsilateral venous effect of the CM injection were rated on a four-point grading scale on CTA images for qualitative assessment.

RESULTSAlthough the attenuation of internal jugular vein and straight sinus were significantly lower in group A than in groups B and C (P<0.05) , the attenuation of aortic arch, superior vein cava, common carotid artery, middle cerebral artery, and basilar artery vessels showed no significant differences among these three groups. The scores of the visualizations of intracranial artery and ipsilateral venous effect of the CM injection were also not significantly different among these three groups.

CONCLUSIONBased on the delay time calculated by a test-bolus injection, a reduced-dose contrast material may provide an equal degree of arterial attenuation and a lower attenuation of vein for dual-energy CTA covering the craniocervical region in second generation dual-source CT system.

This study was aimed to investigate the expression of GST-CML28 in Escherichia Coli and to prepare its antibody. The constructed recombinant expression vectors CML28-pGEX-3X were transformed into Escherichia Coli BL21 under IPTG induction. The protein was abstracted from the transformers, and purified by a GSTrap FF column. The rabbits were immunized by the purified fusion protein to produce serum with anti-CML28 antibody. The serum was purified by chromatographic column stuffed with glutathione Sephamse 4B to get the antibody. The specific antibody against CML28 was further identified by ELISA, Western blot, immunohistochemistry and quantum dot luminescence. The results indicated that GST-CML28 fusion protein was expressed in Escherichia coli and its specific polyclonal antibody was obtained. It is concluded that the anti-CML28 polyclonal antibodies with high titer and specificity are successfully prepared. These antibodies provide an useful experimental tool to profoundly research the physiological significance and biological function of the CML28 gene.

To investigate the antiviral efficacy of combination therapy with pegylated-interferon alpha (peg-IFNa)-2a and ribavirin (RBV) in hepatitis C patients with liver cirrhosis after splenectomy or partial splenic embolization. Forty-nine hepatitis C patients with liver cirrhosis who were unable to use antiviral therapy because of hypersplenism were recruited for study and treated with splenectomy or partial splenic embolization. Three months later, a regimen of antiviral combination therapy was initiated with peg-IFNa-2a (once-weekly subcutaneous injection: 135 μg or 180 μg) and RBV (daily oral: 800 to 1200 mg), and was maintained for 48 weeks. The patients were followed up at treatment weeks 1, 2, 4, 6, 8, and 12. Thereafter, follow-up was conducted every four weeks. The patients were observed until 24 weeks after treatment discontinuation. Follow-up testing included liver function, blood chemistry, renal function, and HCV RNA level. Any adverse reactions were recorded. Liver cirrhosis patients complicated by hypersplenism can be treated effectively with peg-IFNa-2a/RBV combination antiviral therapy after splenectomy or partial splenic embolization. The antiviral-induced sustained viral response rates was 65.00% in cirrhotic/hypersplenic hepatitis C patients receiving splenectomy and 58.62% in those receiving partial splenic embolization. Hypersplenism patients with hepatitis C-related cirrhosis achieved a good antiviral therapeutic effect with peg-IFNa-2a/RBV combination therapy following splenectomy or partial splenic embolization. This sequence of treatment may help to decrease incidences of chronic hepatitis C-induced liver failure and liver cancer in these patients.

OBJECTIVETo study the relationship between blood pressure control status and patients' knowledge on hypertension prevention and control among hypertensive patients.

METHODSA total of 726 hypertensives were selected from four community health service centers (2 urban and 2 rural) in Beijing. All subjects were investigated by questionnaires and their blood pressures were measured at the same time.

RESULTSThe rate for blood pressure under control (< 140/90 mm Hg, 1 mm Hg = 0.133 kPa) in the rural and urban patients were 46.4% and 23.9% respectively. The control rate increased with the increase of patients' knowledge on prevention and control of hypertension in both urban and rural patients. The cumulative effect of knowledge on hypertension control status could contribute 30.0% to the difference in hypertension control rate between rural and urban patients.

CONCLUSIONPatients' knowledge on hypertension control was significantly related to the rate on hypertension control. Health education should be helpful to improve the rate on hypertension control.

OBJECTIVETo evaluate the ASES, Constant and HSS score systems and their significance on postoperative function of the shoulder.

METHODSTotally 172 cases of proximal humeral fracture of five affiliated hospital from September 2004 to September 2008 were analyzed. All the functional outcome of the involved shoulder were evaluated by ASES, Constant, HSS score and patient self score. The correlations and agreement of three shoulder scales were analyzed with Pearson correlation test and Bland-Altman plot in different age groups and fracture types.

RESULTS(1) The Constant score were lower than other two scores in the same age group and fracture type (F = 13.62 and 4.80, P < 0.05). (2) The correlations between three shoulder scales: ASES and Constant (r = 0.754, P = 0.0003), ASES and HSS (r = 0.755, P = 0.0001), Constant and HSS (r = 0.858, P = 0.0002). The correlations between three shoulder scales and patient self evaluation: ASES (r = 0.602, P = 0.0002), Constant (r = 0.705, P = 0.0001), HSS (r = 0.663, P = 0.0037). The Bland-Altman plot shows three shoulder scales have good agreement. (3)The correlation between Constant score and patient self evaluation decreased in the elder group and severe fracture type.

CONCLUSIONSASES, Constant, HSS shoulder score systems are all fit to evaluate the functional outcome of the shoulder, they have good correlation and agreement. Constant score in recommended for its high correlation coefficient with patient self evaluation score. However, its age bias must be paid attention in clinical practice. ASES shoulder score can be used in remote follow-up.
