0.05). Flow cytometry analysis by diff erent gates showed the transfection ratio was high in BMSCs in the period of pro d uctive metabolism. The mRNA expression of CAR in P3, P6 and P8 was similar, and the same change was observed in the protein expression of CAR in P3 and P8 BMSCs . CONCLUSION: Ad-CMV-GFP is transferred to BMSC effectively and sustained about 28 days. It is suspected that BMSCs in mitotic phase are easy to be transferred by Ad-CMV-GFP and different passages of BMSCs from P3 to P8 BMSCs can be as high-effectively g ene vehicle.

With the economic growth and better standards of living,the prevalence of non-alcoholic fatty liver disease (NAFLD) is expected to increase dramatically worldwide.NAFLD is a common chronic inflammation disease.NF-κB is a transcription factor that plays crucial roles in inflammation,immunity,cell proliferation and apoptosis.It can facilitate the occurrence and development of NAFLD,and the underlying mechanisms are related to insulin resistance,oxidative stress,alteration of intestinal flora,activation ofrenin angiotensin system,etc.

Objective To determine the changes of serum glycosylphosphatidylinositol specific phospholipase D(GPI-PLD) activity in patients of several liver disease.Method Glycosylphosphatidylinositol (GPI) anchored placental alkaline phosphatase(PLAP) prepared by ourselves was used as a substrate.After partitioning by triton-X-114,the serum GPI-PLD activity was determined quantitatively and the data was treated by microware of SPSS 10.0.Results On the basis of the percentage of GPI-anchored PLAP conversion,the sera GPI-PLD activities of total 172 patients,included 26 severe acute viral hepatitis as group A,29 liver cirrhosis as group B,32 chronic viral hepatitis as group C,55 mild acute viral hepatitis as group D,30 primary hepatocellular carcinoma as group E,were measured.As compared with 182 healthy presons as control group,the sera GPI-PLD activities of group A and B were significantly reduced;By contraries,the activities of group D and E were significantly raised.The sera GPI-PLD activities of group C compared with healthy control group were not significantly altered.However,when paired Q-test,the changes of serum GPI-PLD activity between all paired groups among this five groups were remarkable.Conclusions The determination of sera GPI-PLD activities in patients can act as a biochemistry index for diagnosis of acute viral hepatitis,liver cirrhosis and primary hepatocellular carcinoma,as well as an auxiliary index for judgment of the curative effect and prognosis of liver diseases.

Objective To explore the early diagnosis and treatment of bronchopulmonary dysplasia (BPD) in premature. Methods Observing and analyzing the onset ,diagnosis of BPD and the outcome treated by dexamethasone in 12 cases that were hospitalized in NICU during the period from January 1994 to January 1999.The follow up study was done for 6 to 12 months after their discharge. Results All of these 12 infants treated by dexamethasone were cured and discharged. The time period of hospitalization was 31 to 67(50?14) days. The one year follow up study after discharge showed that the prognosis of 11 patients were good, only 1 infant suffered from repeated respiratory tract infection. Conclusion Careful observation on clinical manifestations and lab work should be done to those premature babies who suffered from BPD easily for early diagnosis. The early application of dexamethasone in infants with BPD showed perfect results.

Objective To explore the operative timing and cause of death in the patients with acute cholangitis of severe type(ACST). Methods The clinical data on the treatment and the prognosis of 116 patients with ACST were analyzed retrospectively. Results 10 cases died during perioperative period.The patients who received operation within 6 hours after toxic shock all survived.Of 8 cases who received operation after 24 hours,7cases died from toxic shock and multiple organ deficiency of function (MODF) within 4 days of post-operation. Conclusion Operation should be performed before toxic shock or mental symptom occurred in the patients with ACST. The earlier the operation was performed, and the better the prognosis was. The main causes of death were delayed operative time,severe complications and senility.

Objective To observe the clinical therapeutic effects of radial optic neurotomy (RON) for central retinal vein occlusion (CRVO). Methods The clinical data of 12 patients (12 eyes) with CRVO who had undergone RON were retrospectively analyzed. The patients were examined by visual acuity and fundus examination, photography, fundus fluorescein angiography, and optical coherence tomography (OCT). The visual acuities of all of the 12 eyes with severe hemorrhage and retinal edema were less than 0.1. A microvitreoretinal blade or CRVO knife was penetrate into the nasal side of the optic disk, and the incision reached the cribriform plate and even the back, and then dissected at the nasal side of the cribriform plate. The postoperative follow-up period lasted 2 to 15 months with the mean of 6.5 months, and the visual acuity, the condition of visual field and ocular fundus of the eyes undergone the surgery were observed. Results In 12 eyes undergone RON successfully, the visual acuity after the surgery improved more or less in 9 (75%), and more than or up to 0.1 in 6. The results of the examinations showed that the retinal edema and hemorrhage disappeared gradually, varicosity mitigated, retinal serous detachment mitigated or disappeared, and macular cystoid edema faded; macular fovea recovered in 3 eyes, optic nerve had a hemorrhage during the operation in 3 eyes, and the dissected part of optic nerve became atrophic afterward in 4. Conclusions RON performed at the edge of the nasal side of the optic disc is safe and effective, which may improve the visual acuity of the eyes with CRVO and mitigate retinal hemorrhage and edema.

Objective To analyze risk factors for surgical site infection(SSI) in cardiac surgery patients,so as to provide basis for making control measures.Methods 215 patients who underwent cardiac surgery in a hospital between January 2012 to December 2014 were investigated,univariate analysis and multivariate logistic regression analysis were used to analyze the related risk factors for postoperative SSI.Results The incidence of postoperative SSI in cardiac surgery patients was 16.28％ (35/215).Univariate analysis showed that the incidence of postoperative SSI was relatively higher in patients aged＞65 years,duration of operation＞5 hours,continuous operation,preoperative hospitalization time ＞7 days,irrational perioperative antimicrobial use,as well as patients with underlying diseases such as hypertension and diabetes mellitus.Multivariate logistic regression analysis indicated that the age,duration of operation,continuous operation,preoperative hospitalization time,irrational perioperative use of antimicrobial agents,and patients with underlying diseases were independent risk factors for SSI in patients who underwent cardiac surgery.Conclusion Incidence of SSI is higher in patients with cardiac surgery,preventive measures should be taken to control risk factors such as duration of operation,so as to reduce the incidence of SSI.

The plant resources, distribution, extraction, pharmacological effects and its application in medicine of flavonoids procyanidins were reviewed based on the literature, in order to provide the basis for further application and comprehensive development.

Objective To construct dual-luciferase reporter plasmids containing the wild type and mutant rat extracellular signal-regulat-ed kinase 1 (ERK1) gene 3' untranslated regions (UTR) which were used to detect rno-miR-15b-5p's putative target gene. Methods The rat ERK1 gene 3' UTR fragment was amplified by polymerase chain reaction (PCR) from PC12 cell cDNA and cloned into pmiR-RB-ReportTM vector. The mutant rat ERK1 gene 3' UTR fragment was obtained by overlap PCR and inserted into pmiR-RB-ReportTM vector. Successful wild type and mutant recombinant plasmids were confirmed by DNA sequencing. PC12 cells were co-transfected with rno-miR-15b-5p mim-ic and pmiR-ERK13' UTR or pmiR-ERK1-mut 3' UTR and then analyzed by dual-luciferase reporter assay system. The achieved mutation sequence of the target site TGCTGCT was mutated to CGAACGT and GTACACG, respectively. Results The wild-type reporter vector pmiR-ERK13' UTR and the mutant reporter vector pmiR-ERK1-mut 3' UTR were successfully constructed. The rno-miR-15b-5p mimic de-creased the activity of pmiR-ERK13' UTR plasmid (P<0.001) but did not decrease the activity of pmiR-ERK1-mut 3' UTR plasmid. Conclu-sion The recombinant pmiR-ERK13' UTR and pmiR-ERK1-mut 3' UTR plasmids were constructed successfully, and luciferase activities demonstrated that the 3' UTR of ERK1 gene might be a potential target of rno-miR-15b-5p.
