Objective To study the ZT glue postpone iodinated oil metabolism in liver. Methods We had intubated into right portal veins for 5 rabbits, injected 131 iodine iodinated oil and ZT glue, successively recorded ? counts of liver region by ? calibration equipment, created local 131 iodine iodinated oil metabolism equation, calculated effective half drained times, and finally observed the liver and lung in pathology. Another 5 rabbits had been merely injected with 131 iodine iodinated oil as the control group. Results Experimental 131 iodine iodinated oil slow group was higher in proportion than the control group, with delaying of effective half drained times. 131 iodine iodinated oil had been retained more proportion within right liver causing damage to liver tissue. Conclusions ZT glue can postpone iodinated oil metabolism in liver.

【Objective】 To investigate the in-vitro anti-inflammatory mechanism of luteolin by observing the effect of luteolin on nuclear factor-kappa B(NF?B) and COX-2 expression as well as DNA-binding activity of NF-?B in RAW264.7 cells activated by lipopolysaccharides(LPS).【Methods】RAW264.7 cells at logarithmic growth phase were allocated to blank control group,model group(treated with LPS) and luteolin groups(treated with 5,15,and 45 ?mol/L luteolin respectively).After being treated with luteolin for 30 min and then incubated with 1?g/mL LPS for 12 hours,the change of prostaglandin E2(PGE2) level was observed by enzyme immunoassay(EIA),DNA-binding activity of NF-?B was detected by electrophoretic mobility shift assay(EMSA),mRNA expression of COX-2 was examined by reverse transcription polymerase chain reaction(RT-PCR),and NF-?B and COX-2 protein expression in RAW264.7 cells was analysed by Western blotting.【Results】Luteolin obviously inhibited the formation of PGE2,decreased DNA-binding activity of NF-?B and down-regulated mRNA expression of COX-2 as well as NF-?B and COX-2 protein expression in RAW264.7 cells activated by LPS.【Conclusion】The antiinflammatory mechanism of luteolin may be related with the down-regulation of COX-2 expression by inhibiting the expression of NF-?B and DNA-binding activity.

As a possible pathogen of blepharitis,Demodex is gradually known by ophthalmologists.Demodex is one of the permanent small parasitic mites in human hair follicle and sebaceous glands,with high infective rate in human body.There are two kinds of Demodex that colonized in human eyelid:Demodex folliculorum and Demodex brevis.The life cycle of Demodex is about 14.5 days.There have been different views on Demodex as the cause of blepharitis.We performed a deep research on the pathogenic characteristics of Demodex and explored the relationship between blepharitis and Demodex.The clinical diagnose methods and diagnose criteria were also summarized to improve the clinical understanding of Demodex blepharitis,which provides a useful clue for the prevention and management of this disease.

Objective: To study the effect of Baihuzhuifeng Pills (BHZFP) on interleukin 1?(IL 1?) secreted by synoviocytes in adjuvant arthritis (AA) rats. Methods: Synovium of knee joints from AA rats were digested by collagenase and tripsin to prepare DSSC(digested synovial single cells). The content of the supernatant fluid was assayed by the radioimmunoassay. Results: BHZFP down regulated IL 1? productions of DSSC.Conclusion: It is suggested that BHZFP be probably inhibit the over proliferation of synoviocyte in AA rats by diminishing IL 1? secretion.

Objective To summarize the experience of clinical diagnosis and treatment for recurrence and progress of relieved myastbenia gravis after thymectomy. Methods 22 recurrent and progressive after relieved pa-tients with myasthenia gravis who underwent thymectomy were retrospectively analyzed. The remission therapy was conducted with combined glucocorticoid and anticholinesterase and its effectiveness was estimated. Results It was 1,17,4 as better Osserman scale Ⅰ , Ⅱ , Ⅲ respectively before operation but 15,6,1 as better Osserman scale Ⅱ , Ⅲ, Ⅳ respectively in recurrence and progress of relieved myasthenia gravis after thymectomy besides 6 with myas-thenic crisis. Complete remission and partial remission were gained in 9 patients and 12 patients respectively. There was 1 hospital-death. Conclusions Recurrence and progress can occur in any patient of relieved myasthenia gravis after thymectomy. Bulbar myasthenia gravis is usually presented as dysphagia. Reasonable administration of glucocor-tieoid could improve majority of recurrence and progress of relieved myasthenia gravis after thymectomy but responses poorly to the anticholinesterases.

Objective To discuss the anatomical and radiographic characteristics of acetabular fossa,and evaluate their value as a reference for achieving the anticipated inclination of the acetabular cup.Methods Sixteen adult normal pelvic specimens were studied.Central axis of acetabular fossa and its intersection with fossa edge and acetabular rim were marked.The radiographic appearance of the two intersections was evaluated.With radiographic templating,the relationship between the top of acetabular fossa and the central axis of acetabular cup at anticipated inclination was identified.Implantation of cementless acetabular cup was performed bilaterally on the pelvic specimens.The acetabular fossa was used as a reference for implantation on one side,and the acetabular positioning device was used on the other side.The discrepancy of acetabular inclination was recorded before and after operation in the two groups.Results Intersection of central axis of acetabular fossa with fossa top edge and acetabular rim corresponded to the most medial and lateral aspect of acetabular sourcil respectively on standard anteroposterior pelvic radiograph.There was close correlation between most medial aspect of acetabular sourcil and central axis of the acetabular cup at anticipated inclination of 40°±5°.For the group of using acetabular fossa as reference,the mean difference of inclination was 0.19°±3.14°(-6°-5°)before and after operation,and the discrepancy was 2.75°±2.89°(-2°-8°)for the control group.The difference between the two groups was statistically significant(t=-2.453,P=0.027).Conclusion In primary total hip replacement,if normal anatomy of acetabulum was found,the anticipated inclination of acetabular cup can be accurately obtained,based on the relationship between the top of acetabular fossa and anticipated inclination of acetabular cup on preoperative templating.

Objective To investigate whether angiotensin Ⅱ (AngⅡ) can regulate the expression of MIF in macrophages via the NF-κB pathway. Methods Western Blot, real time RT-PCR and ELISA were used in the present study. Results Western blot result showed that the expression of NF-κBp65 gradually increased with the increase of the concentration of AngⅡ. Results of real time RT-PCR and ELISA revealed that MIF mRNA expression and the content of MIF were significantly higher in AngⅡ group than those in the control group. PDTC could reverse the effect of AngⅡ on MIF mRNA expression and MIF secretion in macrophages. Conclusion AngⅡ can promote MIF mRNA expression and MIF secretion in macrophages via the NF-κB signaling pathway.

[Summary] During the past 10 years, the prevalence of obesity and type 2 diabetes mellitus ( T2DM) worldwide has increased greatly.Western dietary pattern is often regarded as the primary causes of the metabolic diseases like obesity and T2DM.A number of other diets have been shown to be effective for the management of obesity and T2DM, such as the Mediterranean diet, the vegetarian diet, the low-calorie diet and the macrobiotic diet.In addition, recent studies have suggested that an imbalance of the intestinal microbiota may be involved in the development of obesity and T2DM.The main regulator of the intestinal microbiota is diet, and the composition of microbiota is impacted by long time diet pattern.This article reviews the recent advance in the influence of different diet patterns on human metabolism and gut microbiota.

Objective To explore the effects of lentivirus-mediated RNA interference targeting HOXA10 gene on the proliferation, apoptosis and drug resistance of leukemic cell line NB4.Methods NB4 cells were divided into three groups: interference group, negative control group and untreated group.The infection efficiency of lentivirus for NB4 cells was detected by flow cytometry, and the expression of HOXA10 gene of NB4 cells at mRNA and protein level was detected by real-time PCR and Western blot.Cell survival was determined by MTF assay, and apoptosis and necrosis rates were detected by flow cytometry.Western blot was used to detect the influence of down-regulation HOXA10 gene on the multi-drug resistance-1 (MDR-1) protein.Results The ratio of GFP positive cells was up to 90 ％.HOXA10 gene mRNA and protein levels were decreased in interference group compared with control group.The inhibition rate of interference group was (52.12±4.02) ％, the apoptosis rate of interference group was (30.0±2.7) ％, and their differences in the interference group and in control groups (negative control group and untreated group) were significant (P ＜ 0.05).Western blot results showed that interfering HOXA10 gene significantly reduced the resistance gene MDR-1 expression level and reverse the drug-resistant of leukemia cells.Conclusions Lentivirns-shHOXA10 can steadily reduce the expression level of HOXA10, inhibit the leukemic cells proliferation, promote apoptosis and reverse drug-resistant.HOXA10 gene is expected to become a new target for reversing leukemia drug resistance.
