Objective To summarize the clinical features,diagnosis and treatment principles of abdomen postsurgical gastroparesis syndrome(PGS).Methods The clinical data of 28 patients with abdomen postsurgical gastroparesis syndrome,collected from our hospital in the past ten years,were analyzed retrospectively.Results All 28 patients were cured by conservation therapy.The average gastric dynamics response time was 20.2 days(12.0～34.0 days),which included 2 cases recovered within 1-2 weeks,17 cases recovered within 2-3 weeks,7 cases recovered within 3-4 weeks,2 cases recovered over 4 weeks.Conclusion PGS is a functional reaction rather than mechanical obstruction disease.The diagnosis mainly depends on the symptoms and sighs combined with gastrointestinal angiography or endoscopy.Most of the patients can be cured by conservative treatment.

Objective: To investigate pharmacokinetics of propofol during anhepatic period of orthotopic liver transplantation (OLT) in children. Methods: In 5 children undergoing OLT, 2 mg/kg propofol was injected intravenously at the beginning of induction and anhepatic periods respectively. The plasma concentration of propofol was measured by reverse-phase high performance liquid chromatography(RP-HPLC), and the pharmacokinetics character of propofol between anhepatic and inducing periods were compared. Results: Propofol had wide distribution and high clearance, and its plasma concentration-time curves were fitted to a three-compartment open model. Conclusion: There is no difference of propofol metabolism between anhepatic and inducing periods, suggesting that there must be notable extra-hepatic metabolism when propofol used in children undergoing OLT.

Objectives:To evaluate the clinical significance of different early nutrition support in severe head injured patients. Methods:140 cases(GCS≤8) were randomly divided into 5 groups.From A to E,each one had 28 cases.The patients in group A received early parenteral nutrition(PN) and enteral nutritoin(EN) together;group B received early PN,and EN after 1 week later;group C received PN only for more than 2 weeks;group D received early EN only;group E received traditional delayed EN.The clinical observation and statistical comparison were taken. Results:Severe head injured patients could get nutrition from different ways at early stage.A and B groups had better outcomes,and the blood glucose and nutritional data were superior to those of D,E group( P

Objective To study the influence of short hairpin RNA-mediated inhibition of APRIL gene on proliferation,invasion and metastasis of human colon carcinoma SW480 ceils in vitro. Methods After treatment with shRNA, the expression level of APRIL protein in human colon carcinoma SW480 cells was detected by western blotting. And cell adhesion, cell migration and cell invasion of SW480 cells transfected with sh637 were analyzed respectively as compared with non-transfected SW480 cells and mocktransfectant. Results The expression of APRIL protein in SW480 transfected with sh637 were significantly lower than mock-plasmid groups and untransfected ones (F=42.15, P=0.00). Cell proliferation was markedly inhibited, compared with untransfected groups and negative control ones (F=24.76, P<0.05).And the average absorption of cell adhesion in transfected groups, mock-plasmid and non-transfected ones were 0.343, 0.409, 0.412, respectively. Cell adhesion decreased 39% compared with untransfected groups. Similarly, there was significant difference for cell migration (F=65.53, P<0.01) between transfected groups (The average ceil number in exposed area to migrate was 47.89±13.16) and nontransfected (98.78±23.26) as well as mock-plasmid ones (108.01±39.11). Then, in view of the average absorption of cell invasion between transfected groups(0.58±0.10) and non-transfected (0.94±0.23) as well as mock-plasmid ones(1.11±0.21), a prominently difference for cell invasion was also found between them (F=5.771, P<0.05). Conclusion The results suggest APRIL has a proliferation-inducing effect and probably be involved in cell invasion and cell metastasis of colon carcinoma and it could enhance capacity of invasion and metastasis of SW480 cells.

This article was aimed to study the correlation between microstructure and stability of cream contained Span and Tween as compound emulsifier by factor analysis. Techniques such as microscopic observation and rheolog-ical examination were used to perform the microstructure. And the thermal analysis and near-infrared stability ana-lyzer was carried out to quantify characterization of the physical stability of cream. The results showed that among the series of S60-T80 and S60-T60 creams based on compound emulsifier, cream conductivity increased and more and more spherical lamellar liquid crystalline structures appear on micrographs with increasing Span 60 fraction. The greatest viscoelastic was appeared when the mass ratio of Span and Tween was 2:2 and 1:3, respectively. From the thermogravimetric analysis, the increase of Span 60 fraction led to the weight loss of samples between 50℃-70℃ in-crease, but it decreased within 70℃-110℃. It was concluded that there was positive correlation between the intensi-ty of microstructure and the ability of resistance to structural failure when the experiment conditions were stable. It had negative correlation with the hydrophilic gel phase water distribution index.

Objective To investigate the association of single nucleotide polymorphism (SNP) in micro RNA-122 (miRNA-122) with genetic predisposition and early recurrence after resection for hepatocellular carcinoma(HCC).Methods This is a case-control study involving 173 HCC patients.DNA were exacted from cancer tissues embedded in paraffin and were amplified by PCR.The study aimed to explore SNP in gene sequence of miRNA-122 (357 base pair including extron.The outcomes of genetic predisposition were analyzed with early recurrence after resection for HCC.Results Only rs17669 was found in miRNA-122.The genetype frequence of C/C,T/T and C/T at rs17669 gene locus were 7(4.0％),110(63.6％)and 56(32.4％),respectively.When compared to T/T genetype,C/C genetype was a protective factor of risk of HCC (OR =0.213,95％ CI:0.062-0.732).Genetypes had no relationship with early recurrence after resection.Conclusion For HCC recurrence,rs17669 may be associated with genetic predisposition of HCC in Hans in Jiangxi infected with HBV.

Methods Thirty SD rats were randomized into sham group and AOLT group. The pathological changes of lung, expression of the relevant inflammatory mediators and oxidative stress markers were detected . Results ( 1 ) Compared with the sham group , the pathological scores of lung tissue in AOLT group increased significantly and reached its peak at 8 h after surgery. Then the pathological scores decreased to the level of sham within 24 h to 48 h after surgery; (2)The relative expression of inflammatory mediators including TNF-α, IL-1β, IL-6 and IL-8 increased significantly and reached its peak at 8 h after surgery in AOLT group. Then decreased to the level of sham group within 24 h to 48 h after surgery; (3)The change trends of MDA and H2O2 were similar to inflammatory mediators.The relative SOD expression decreased significantly and touched the nadir at 8h after surgery and then increased. Conclusion The pathological changes of lung expression, the relevant inflammatory mediators and oxidative stress markers of rats underwent AOLT were consistent.
