Objective To investigate the variation of cytokines IL-4, IL-1? and TNF-? before and after the onset of pregnancy induced hypertension (PIH) and to discuss the role of cytokine in the pathogenesis of PIH. Method A prospective cohort study of 550 pregnant women were followed. Plasma drawn from 25 women who developed moderate and severe PIH and 30 controls at 12~16 and 32~36 gestational weeks were analyzed. The concentrations of IL-4, IL-1? and TNF-? were analyzed using ELISA method. Results (1)In the second trimester, the plasma level of TNF-? in PIH group was significantly higher than control group(27.66 ng/L vs 17.80 ng/L, P

Objective To explore the interactive effect of acupuncture and exercise on severe traumatic brain injury (TBI). Methods 120 comatose patients following TBI after routine surgery were equally divided into combined group (acupuncture and exercise), acupuncture group, exercise group, and control group (neither acupuncture, nor exercise). They were assessed with Glasgow coma scale (GCS),Fugl-Meyer assessment (FMA), modified Brathel index (MBI) and neurological deficit scores (modified Edinburgh-Scandinavia stroke scale, MESSS) before and after the treatment. Results The scores of GCS, FMA, MESSS and MBI improved more in the combined group than in the control group (P<0.05). The scores of GCS and MESSS improved more in the acupuncture group and the exercise group than in the control group (P<0.05). The scores of MESSS improved more in the combined group than in the exercise group (P<0.01). Conclusion Both acupuncture and exercise can synergetically reduce the disability and coma of comatose patients following TBI.

Objective To explor the operative method of modified pericardial devascularization and compare the effects of modified pericardial devascularization and traditional pericardial devascularization on esophageal gastric varices of liver cirrhosis with portal hypertension. Methods The clinical data of 35 patients receiving modified pericardial devascularization (MED group) and 35 patients receiving traditional pericardial devascularization (ED group) were retrospectively analyzed . Results The operating time in MED group was significantly lower than that in ED group:(182 ± 30)min vs.(220 ± 30) min, P<0.05. The blood loss in MED group was significantly lower than that in ED group:(200 ± 15) ml vs. (300 ± 100) ml, P<0.05. Early complication rate in MED group was significantly lower than that in ED group:5.7%(2/35) vs. 22.9%(8/35), P<0.05. The esophageal gastric varices of patients who were followed up in MED group and ED group were almost equal (P>0.05). Conclusions The operating time, blood loss and early complication rate in modified pericardial devascularization is better than traditional pericardial devascularization. There is no significant difference in long-term efficacy between two methods.

Objective:To study of immuno-intervention with prostaglandin E2(PGE_2) on tumor necrsis factor(TNF-?),interleukin 10(IL-10),SOD and NO in rats attacked by vibrio vulnificus.Methods:27 normal rats and 27 hepatopathy rats,they were divided into Vv attacked group,ofloxacin treatment group and combined PGE_2 with ofloxacin protect group(n=9).Results:The result of cytokines detection showed that serum IL-10 and SOD level of combined PGE_2 with ofloxacin protect group was significantly higher than that of ofloxacin treatment group,however,TNF-? and NO level of PGE_2 immuno-protect group were significantly lower than those of ofloxacin treatment group(P

OBJECTIVE: To investigate the changes of ultrastructure of biliary epithelia with ischemic-type biliary lesion (ITBL) and the protection effect of exogenous growth hormone (GH) in order to provide experimental information for prevention of biliary complication after liver transplantation. METHODS: Rats underwent liver transplantation were randomized into control group, ITBL group and recombinant human growth hormone (rhGH) group (n=6, respectively). Each group was given drugs at the same day postoperation. 7 days later, the specimen of bile ducts was collected. The epithelial changes of biliary tract were observed with TEM, and the injury degree of the epithelia was analyzed quantitatively in a specialized image analysis system. The epithelial plane measurement parameters of each group were measured, including the density of area and quantity of epithelia, and the density of area of epithelial microvilli. RESULTS: As compared with control group, in ITBL group the integrity of bile ducts was destroyed, epithelial microvilli became sparse, the epithelial plane measurement parameters were significantly decreased (P

Objective: To determine the relation dynamic contrast-enhanced magnetic resonance imaging (MRI) and histologic features and angiogenesis of breast disease. Methods: Forty patients with breast disease, diagnosed by histopathology were reviewed, including imaging and pathological data. Dynamic MRI was performed by a fat-suppressed 3D-FSPGR sequence ,Time-Signal curve was acquired by Functool 2 software, then early-phase enhancement rate and E max , T max were acquired. The mean MVD and VEGF expression of the lesions were measured with immunohistology. Evaluation of inflammatory changes was assessed by histology. Results: The MVD , VEGF expression and inflammatory scores of malignant tumor were significantly higher than that of benign tumor(P0.05), The Time-SI curve between malignant and benign was significant different(P

OBJECTIVE To analyze the risk factors and the drug-resistance of nosocomial acquired lung infection by Chryseobacterium meningosepticum.METHODS A retrospective investigation of the clinical correlative data and the drug sensitivity results of 60 cases with nosocomial acquired lung infection by C.meningosepticum from Jan 2004 to Jan 2006 was conducted in local hospital.RESULTS The patients were mainly distributed at ICU,respiration and neurosurgery wards.They had severe underlying diseases(100.0%),tracheal intubation(56.7%),central venous catheter(25.0%) and urine catheter(16.7%) treatments and applications of more than three antibiotics(68.3%).The drug-resistance of C.meningosepticum was serious.The antibiotic drugs which had higher susceptibility ratio were cefoperazone/sulbactam,fluoroquinolones,et al.CONCLUSIONS The main risk factors of nosocomial acquired lung infection by C.meningosepticum are severe underlying diseases,various invasive treatments,long-term hospitalization and inappropriate use of broad spectrum antibiotics.Clinical isolates are multi-drug resistant to many kinds of antibiotics.

Objective To research the relationship between the gene polymorphism of serum amyloid A protein(SAA)1 and coronary heart disease(CHD).Methods By using PCR-RFLP and sequencing,the gene polymorphism of SAA1 of 183 patients with coronary heart disease and 152 healthy controls were analyzed.Result In the both groups 3 alleles(1.1,1.3,1.5)and 6 genotypes(1.1/1.1,1.1/1.5,1.1/1.3,1.3/1.3,1.3/1.5 and 1.5/1.5)were found.The frequency of 1.5 allele in healthy controls group was notably higher than that in CHD group(P

Objective To study on glutathione and glutathione-related enzymes of Antarctic ice microalgae.Methods Glutathione(GSH) content,glutathione produce ability(GPA) and glutathione reductase(GR) activity in 24 kinds of Antarctic ice microalgae were assessed using the spectrophotometer methods.Results GSH content of Cyanophyceae B-1 was highest.Total GSH yields of Antarctic ice microalgae Chlamydomonas sp.ICE-L and Berkeleya rutilans GJ01 were in the top two positions.GPA in most Antarctic ice microalgae was higher than that in mesophilic green algae,and only in two ice microalgae was lower than that in Phaeodactylum tricornutum.GR activities of Antarctic ice microalgae Berkeleya rutilans GJ01 and Chlamydomonas sp.ICE-L were greater than that of the control microalgae.Conclusion It is possible that Antarctic ice microalgae will become a new resource of GSH.
