Objective To explore the effective of minimally invasive techniques for diagnosis and treatment of the spinal fungal infec-tions. Methods The clinical data of 6 patients with spinal fungal infection in our hospital from January 2012 to June 2014 was reviewd. All patients were taken biopsy diagnosis for spinal fungal infection by percutaneous endoscopic lumbar discectomy. Along with the oral antifungal drugs treatment,all the patients received the interbody fusion surgery by percutaneous pedicle screw fixation and debridement. The clinical and image data were collected during the 6 months following period. Results The symptoms of all the patients was relieved after surgery and no complications occurred. All the patients were followed up for 6 months. The value of ESR and CRP decreased to normal level at the first month after operation. The VAS scores decreased from (7. 0 ± 0. 8) to (0. 8 ± 0. 7) and the ODI scores decreased from (56. 1 ± 7. 7) to (5. 7 ± 2. 1). The X-ray image confirmed solid fusion at the 6 months after surgery. Conclusion The minimally invasive technique of spine is a good way to treat spinal fungal infection.

OBJECTIVE:To study inhibitory effects in vivo and in vitro of gemcitabine on liver cancer. METHODS:MCF-7 cells and HepG2 cells were treated with different concentrations of gemcitabine solutions(5,10,20,30,50,70 and 90 μmol/L). The absorbance of cells was determined by MTT assay after treated for 24,48 and 72 h. The inhibition ratio and 50% inhibiting concentration(IC50) of cells were calculated. Tumor-bearing mice were established by inoculating 0.2 ml liver cancer H22 cell line via right anterior axillary,and then randomly divided into control group(normal saline)and gemcitabine group(40 mg/kg)with 5 mice in each group. They were given relevant medicine intravenously every 2 days,for 3 times. The changes of body weight and in-hibition ratios were recorded. RESULTS:Gemcitabine can inhibit MCF-7 cells and HepG2 cells,and IC50 of gemcitabine to them were 30 and >90 μmol/L within 24 h respectively,and those of gemcitabine to them were all lower than 5 μmol/L after 48 h and 72 h. There was no statistical significance in body weight of tumor-bearing mice between 2 groups,and inhibitory rate of gemcitabi-ne to H22 cell line was 75.76%. CONCLUSIONS:Gemcitabine can inhibit liver cancer in vivo and in vitro.

Many researches have focused on the wnt-frizzled cascade in the recent years, while much work has been done in neoplastic diseases and embryology, the role of the wnt-frizzled signal transduction pathway in cardiovascular diseases has only recently begun to be explored. It plays a very important role in many physiological and pathophysiological processes, such as its transduction pathway, the healing after myocardial infarction, the proliferation, differentiation and orientation of cardiomyocytes, angiogenesis/neovascularization, cardiac hypertrophy and heart failure, the deposition of the extracellular matrix and so on. This article is aimed at its relation with myocardial infarction and the role of this pathway in cardiovascular diseases.[

Objective To report the clinical effects of microsurgery in treatment of infected extremities after blood vessel prosthesis were transplanted.Methods From Jan.1998 to Dec.2008,8 cases of major vascular injuries in extremities were blood-supplied by cross bridge vascular anastomosis from uninjured extremities,including 4 cases of femoral artery and vein,2 cases of popliteal artery and vein,and 2 cases of brachial artery and vein. Results After 3 years of follow-up,blood circulation of infected extremities were reestablished in each of 8 cases,as well as function and appearance recovered.Conclusion The procedure of cross bridge vascular anastomosis from uninjured extremities may efficiently restitute the blood supply of the infected extremities after blood vessel prosthesis were transplanted,and decrease the rate of amputation.

Biomacromolecules play an important role in the treatment of many diseases, but as a result of cell membrane serving as the natural barriers, only the small molecular compounds whose molecular weights are smaller than 600 Da can get through cell membrane and enter the cell. In recent years, some short peptides (the length less than 30 amino acids) are found to have the cell-penetrating function, called cell-penetrating peptides (CPPs). They are able to effectively translocate segments of protein, polypeptides, nucleic acid into the cells of many mammal animals with many methods. They have high transduction efficiency and will not lead to cell damage. So, the discovery of CPPs has a very good applicable prospect in such research fields as cell-biology, gene-therapy, drug transduction in vivo, evaluation of clinical medicine and medical immunology. This paper reviews the types and characteristics of CPPs, internalization mechanisms, applications, and their existing problems.

To investigate the chemical constituents of the endophytic fungus Penicillium sp. FJ-1 of Ceriops tagal, the chemical constituents were isolated by column chromatography on silica gel and Sephadex LH-20. Their structures were elucidated on the basis of spectroscopic analysis. Their antibacterial activity was tested by paper disco diffusion method. Two compounds were isolated and identified as 7-hydroxy-deoxytalaroflavone (1), and deoxytalaroflavone (2). Compound 1 is a new compound, and compounds 1 and 2 showed weak activity against Staphylococcus aureus and methicillin-resistant Staphylococcus aureus.

Objective To investigate the survival rate, voiding, sexual function after nerve-sparing surgery with extended systematic extraperitoneal lateral lymphadenectomy in lower rectal cancer. Methods Three hundreds and ninety-two cases with advanced lower rectal cancer who underwent nerve-sparing surgery with radical dissection from 1996 to 2000 were reviewed. Among them,173 cases only cleared in abdominal cavity,219 cases coupled with extraperitoneal lateral lymphadenectomy. Results The metastatic rate of lateral lymph node was 17.8%(39/219),the rate of non-modal foci of metastatic disease in lateral out of the abdominal cavity was 5.9%(13/219).Local recurrence rate, the abdominal cavity group was 16.2%(28/173); the coupled group was 9.6%(21/219), P

Objective To evaluate the role of prostaglandin E2 (EP) receptors in H9c2 cardiomyocyte hypertrophy induced by prostaglandin E2 (PGE2).Methods Primary cultured H9c2 cardiomyocytes were seeded in culture flasks (3 ml/flask) or in 24-well plate (1 ml/hole) or 6-well plate (2 ml/hole) with density of 4 × 104/ml.The cells were randomly divided into 4 groups (n=24 each): control group (group C),PGE2 group,AH6809 (EP1 and EP2 receptor antagonist) group (group A) and GW627368X (EP4 receptor antagonist) group (group G).The cells were continuously cultured for 48 h.PGE2 (final concentration 1 μmol/L) was added to the culture medium in PGE2 group.PGE2 (final concentration 1 μmol/L) and A H6809 (final concentration 10 μmol/L) were added to the culture medium in group A.PGE2 (final concentration 1 μmol/L) and GW627368X (final concentration 10 μmol/L) were added to the culture medium.The cells were then cultured for 48 h in groups PGE2,A and G.Then the cell morphology was observed by using fluorescent microscope.The cell diameter was measured by using the Image J medical image analysis system.Total protein content in the cells was measured with BCA method.The expression of atrial natriuretic peptide (ANP) mRNA and brain natriuretic peptide (BNP) mRNA in the cytoplasm was determined using RT-PCR.Results Compared with group C,the total protein in the cells and cell diameter were significantly increased,and the expression of ANP mRNA and BNP mRNA in the cytoplasm was up-regulated in groups PGE2,A and G (P ＜ 0.05).Compared with group PGE2,the total protein in the cells and cell diameter were significantly decreased,and the expression of ANP mRNA and BNP mRNA in the cytoplasm was downregulated in group G (P ＜ 0.05),and no significant change was found in the parameters mentioned above in group A (P ＞ 0.05).Conclusion EP4 receptor mediates H9c2 cardiomyocyte hypertrophy induced by PGE2 and the effect is not related to EP1 and EP2.
