Objective To investigate the clinical efficacy of CRRT in the treatment of severe pancreatitis.Methods 120 patients with severe pancreatitis were divided into two groups according to the treatment.All the patients were given basic treatment in all groups.The Pa arterial oxygen pressure (PaO2),oxygenation index (PaO2/FiO2),and C-reactive protein (CRP) in the two groups after 72 hours of treatment were observed.The levels of blood lactate (Lac),APACHEII,tumor necrosis factor α(TNF-α),interleukin-6 (IL-6) and interleukin-1β (IL-1β) were measured before and after treatment 72 hours.A comparison of mortality and hospitalization time was observed in 28 days of treatment.Results After treatment,Lac [the control group (3.32±0.85)mmol/L,the observation group (2.55±0.65)mmol/L],APACHEII score [the control group (13.30±2.80)points,the observation group (12.01±2.60)points],CRP [the control group (24.30±2.80)mg/L,the observation group (12.33±1.60)mg/L] were significantly lower than before treatment [Lac:the control group (4.85±1.05)mmol/L,the observation group (4.90±1.02)mmol/L;APACHEII score:the control group (16.62±2.95)points,the observation group (16.90±3.01)points;CRP:the control group (40.32±3.10)mg/L,the observation group (40.40±3.51)mg/L;the control group:tLac=1.67,P=0.004,tAPACHEII=6.32,P=0.000,tCRP=29.71,P=0.000;the observation group:tLac=15.05,P=0.005,tAPACHEII=9.52,P=0.000,tCRP=56.36,P=0.000].PaO2 [the control group (75.30±4.80)mmHg,the observation group (84.31±4.60)mmHg], PaO2/FiO2 [the control group (225.30±14.83)mmHg,the observation group (256.31±14.65)mmHg] were significantly higher than before treatment [PaO2:the control group (60.32±4.15)mmHg,the observation group (60.40±4.01)mmHg;PaO2/FiO2:the control group (130.39±11.15)mmHg,the observation group (130.90±11.01)mmHg;the control group:tPaO2=18.29,P=0.000,tPaO2/FiO2=39.62,P=0.000;the observation group:tPaO2=30.35,P=0.000,tPaO2/FiO2=53.01,P=0.000].Those in the observation group were significantly improved than the control group (tLac=5.574,P=0.00,tAPACHEII score=2.615,P=0.005,tPaO2=3.646,P=0.0002,tPaO2/FiO2=11.523,P=0.00,tCRP=28.751,P=0.000).After treatment,the TNF-α,IL-6 and IL-1β levels in the two groups [the control group:IL-1β (70.32±6.85)ng/mL,IL-6 (103.30±8.80)ng/mL,TNF-α (89.30±8.80) ng/mL;the observation group:IL-1β(48.55±6.62)ng/mL,IL-6(92.01±8.60)ng/mL,TNF-α(57.31±7.60)ng/mL] were significantly improved than before treatment [the control group:IL-1β(82.85±7.05)ng/mL,IL-6(173.62±9.95)ng/mL,TNF-α (105.32±9.15)ng/mL;the observation group:IL-1β(83.90±7.32)ng/mL,IL-6 (175.90±10.01)ng/mL,TNF-α (106.40±9.01)ng/mL;the control group:tIL-1β=9.66,P=0.000,tIL-6=41.01,P=0.000,tTNF-α=9.77,P=0.000;the observation group:tIL-1β=27.74,P=0.000,tIL-6=49.23,P=0.000,tTNF-α=32.26,P=0.000].And those of the observation group improved more significantly than the control group (tIL-1β=17.702,P=0.00,tIL-6=7.107,P=0.00,tTNF-α=21.311,P=0.000).The mortality rate and hospitalization time of the observation group were 18.33% and (10.97±2.92)days,which were significantly lower than those of the control group [36.67%,(13.63±3.26)days;χ2=5.058,P=0.025;t=4.708,P=0.000).Conclusion The use of CRRT in the treatment of severe pancreatitis can improve the vital signs,reduce the inflammation index,improve the serum levels of inflammatory factors and lactic acid,reduce the mortality and hospital stay.

The brainstems of 6 rabbits were cut transversely in series and stained fornerve cells or myelin.The architecture of the parabrachial nucleus was studied.Be-sides general observation the length and width of 100 nerve cells in each of the 5nuclear areas chosen were measured and analysed statistically with the help of adigital computer.The following items were calculated:ratio of length to width,itsmean and 95% tolerance interval;area of nerve cells,its mean and 95% toleranceinterval;80% elliptical contour of normal bivariates for the length and width of thecells;cluster analysis of the more dispersed nuclear areas and 80% elliptical contourof each cluster. We concluded that the parabrachial complex consists mainly of 3 nuclei,viz.medial parabrachial nucleus,lateral parabrachial nucleus and magnocellularparabrachial nucleus.Dorsal to the medial parabrachial nucleus there is asmall area,which was tentatively called“d”area in the present study.The medial parabrachial nucleus lies medial to the brachium conjunctivum.Its cells are more or less round in shape,varying markedly in size and canbe clustered into 3 groups according to their size.The lateral parabrachial nucleusis located lateral to the brachium conjunctivum.Its cells are smaller than those ofthe medial nucleus,mostly spindle in shape.Some larger cells can also be seen scat-tered among the smaller ones and the process of clustering has yielded 2 groups ofcells.The magnocellular parabrachial nucleus can be seen in the middle range ofthe nuclear complex.It lies ventrolateral to the brachium conjunctivum with denselypacked large round cells.Its demarkation with the surroundings is sharp.A dorsalextension of this nucleus can be seen wedging between the brachium conjunctivumand the lateral parabrachial nucleus.Its cells are also large and compacted but arespindle in shape.Cells of the“d”area are small and round.Its relation with eitherthe medial or the lateral parabrachial nucleus remain unsettled.The relation between the parabrachial nucleus and the K(?)lliker-Fuse nucleuswas discussed.

As to a nitrite-oxidizing bacterium screened in our laborator y, the effect of pH, nitrogen sources, carbon sources and sodium chloride on its g rowth was studied in order to obtain high cell density. It showed that the cult ure conditions of nitrite- oxidizing bacterium were 4500mg/L sodium nitrite, 1 .5g/L sodium carbonate, 0~0.5% sodium chloride and 0~0.1% glucose at 28℃~30 ℃, 110 r/min and pH 8.0~8.5. After cultivation for 9 days, the bacteria conc entration reached 4.6?109 MPN/mL and all NO-_2-N in the medium w as converted to NO-_3-N. But the transformation of nitrogen sources was inhibited while the sodium chloride concentration exceeded 0.5% or glucose con centration exceeded 0.1%. According to the test of NO-_2-N conversion with nitrite-oxidizing bacteria in a freshwater aquaculture pond, NO-_2 -N began to decrease on the third day of the moculation of this bacterium and t he concentration dropped from 1.47mol/L to 0.49mol/L after 18 days at 25℃ and pH 8.6.

Interleukin 18 (IL 18) is emerging as a powerful, pleiotropic cytokine involved in determining the polarization of T cell responses. To identify the effect of IL 18 on hepatitis B virus, mouse IL 18 gene was transferred and expressed in 2.2.15 cells. Meanwhile, the inhibition of HBsAg, HBeAg and HBV DNA was investigated. Reverse transcription polymerase chain reaction (RT PCR) was used to amplify the mouse IL 18 from spleen cell of Balb/c mouse challenged with lipopolysaccharide (LPS) and phytahematoagglutinin (PHA), and reconstruct plasmid pLXSN IL18 with the retroviral vector pLXSN. Both pLXSN IL18 and pLXSN were transfected into PA317 cells and then 2.2.15 cells were infected by using the supernatant containing pseudovirus released by PA317. HBsAg and HBeAg were detected by ELISA and the HBV DNA was determined by quantitative PCR. The 580bp of mIL 18 was cloned into retroviral vector pLXSN. The pseudovirus contained in the supernatant of transfected PA317 cells was identified by RT PCR. When the pseudovirus was infected into 2.2.15 cells and incubated for 3, 5, 7, 14 days, the P/N value of HBsAg and HBeAg decreased gradually and became negative on day 14. The copies of HBV DNA reduced markedly. The results indicate that mIL 18 gene expressed in 2.2.15 cells can significantly inhibit the replication expression of HBV and may be used as a potential agent for gene therapy against HBV infection.

Protein protein binding is the basis of virus and host cell interactions. With the application of technology of studying of protein interactions, more knowledge of replication and pathogenesis of hepatitis C virus (HCV) could be acquired. Non structure protein NS5A is one of the important regulatory factors in virus replication , transcription and signal transduction, but there are controversy in effect on HCV pathogenesis and resistance to interferon ?(IFN?). In order to describe the relationship between NS5A and host proteins, we use yeast two hybrid system 3 to screen the gene encoding proteins that could interact with NS5A from human hepatocyte library. Thirty five clones were obtained including apo A1, apo A2, apo B100, haplotype mitochondrion complete genome, phosphatidic acid phosphatase type 2B, albumin similar to tumor endothelial marker 5 precursor, matrix metalloproteinase 14, and three of the Homo sapiens hypothetical proteins. The study paved a way for further studies on the pathogenesis of HCV NS5A
