Objective To investigate the expression of human β defensin-2(hβD-2)in the eutopic and ectopic endometrial tissue in patients with adenomyosis and in women with normal endometrium.Methods Twenty-five hysteromyoma patients with adenomyosis(AM) and 25 hysteromyoma patients without endometriosis (EMS) were selected and divided into three groups:AM ectopic endometrium group,AM eutopic endometrium group and control group( endometrial tissue in patients with hysteromyoma).The level of mRNA expressions of hβD-2,interleukin-1β ( IL-1β ),interleukin-6 ( IL-6 ) and tumor necrosis factor-α (TNF-α) was investigated quantitatively using Real Time PCR (RT-PCR) and the corresponding protein level was detected by immunohistochemistry.Results Comparing the expression of hβD-2,IL-1β,IL-6,TNF-α genes among the three groups,there was no significant difference between ectopic endometrium group and eutopic endometrium group and there was also no significant difference between eutopic endometrium group and the control group.( P ＞ 0.05 ).The expression of hβD-2 and IL-1β were 0.0320 (0.0095 ～ 0.0690 ) and 0.0427 ( 0.0038 ～ 0.0975 ) in the ectopic endometrium group,and they were 0.0034(0.0025 ～0.0424) and 0.0080(0.0040 ～0.0251 ) in the control group,respectively.They were both significantly higher in ectopic endometrium group than in the control group (P ＜ 0.05 ).In the ectopic endometrium group hβD-2 expression was positively correlated with the level of TNF-α ( r =0.857,P =0.014 ),and it had no correlation with both IL-1β and IL-6 ( r =0.750,P =0.052 ; r =0.464,P =0.464; respectively)Conclusion HβD-2 might not play an important role in the formation of adenomyosis.It may be related to no significant up-regulation of inflammatory factors in ectopic lesion tissue.

ObjectiveTo explore the therapeutic effect of continuous veno-venous hemofiltration (CVVH) on the treatment of severe acute pancreatitis (SAP).MethodsAll data about forty-five patients with SAP admitted to the intensive care unit (ICU) from June 2005 through June 2010 were reviewed.These 45 patients were randomly (random number ) divided into routine treatment group (n =22 )and comprehensive treatment group ( n =23 ).In control group,patients were rapidly given with a suffficient liquid support,vasoactive drug to increase organ perfusion,trypsin secretion inhibitor,broad-spectrum antibiotics,enteral nutrition with intestine membrane protective agent in early stage.In the comprehensive treatment group,patients received CVVH integrated with routine treatment.On admission and 72 h posttreatment,the scores of acute physiology and chronic health evaluation Ⅱ ( APACHE Ⅱ ) and multiple organ dysfunction syndrome (MODS),and the results of standard bettery of biochemistry tests indcluding blood urea nitrogen (BUN),serum cratinine (Scr),total bilirubin (TBIL),alanine aminotransferase (ALT),amylase (AMS),C-reactive protein (CRP),TNF-α,IL-6,IL-8 were observed.Time of mechanical ventilation support,length of ICU stay,and survival rate were compared between two groups.ResultsOn admission between the two groups,no statistical significance was seen in the APACHE Ⅱ and MODS score,BUN,Scr,TBIL,ALT,AMS,CRP,TNF-α,IL-6,IL-8 (P ＞ 0.05).But APACHE Ⅱ and MODS score were decreased significantly in comprehensive treatment group than in the routine treatment group,as well as the the level of BUN,Scr,TBIL,ALT,AMS,TNF-α,IL-6,IL-8 and CRP after 72h post-treatment (P＜0.05 ).In routine treatment group and comprehensive treatment group,the time of respirator intervention and length of stay in ICU were (7.6±3.4) d vs.(11.5±4.7) d,(12.3±7.8) dvs.(17.6±9.2) d respectively,the statistical significance was shown ( P ＜ 0.05 ).Compared to the comprehensive treatment group ( 86.96％ ),the survival rate ( 59.09％ ) were lower in routine treatment group ( P ＜ 0.05 ).ConclusionsCVVH combined with routine treatment,which can remove inflammatory agents and toxins,maintain homoeostasis,and improve oxygenation,is effective in treatment of SAP and can improve patient survival rate.

Objective To investigate the application of dual volume reconstruction translucent imaging in performing stent- assisted coil embolization for intracranial aneurysm embolization treatment. Methods During the period from Nov. 2011 to Sep. 2012, a total of 30 patients with intracranial aneurysm were admitted to authors’ hospital. Stent-assisted coil embolization was carried out in all patients. The number of all the stent point-marks visualized on routine 2D-DSA, on rotational angiography (3D-RA) and on dual volume reconstruction translucent images were determined, and the results were compared between each other of the three imaging methods. Results A total of 34 stents (206 stent point-marks in total) were implanted in the 30 patients. Of the 206 stent point-marks, 2D-DSA, 3D-RA and dual volume reconstruction translucent image could clearly display 146 (70.8%), 123 (59.7%) and 190 (92.2%), respectively. Statistically significant difference in the displaying rate of the stent point-marks existed between each other among the three imaging methods (P < 0.05). Conclusion Dual volume reconstruction translucent imaging can distinctly display the location of the stent marks, which is of great value in guiding the performance of intracranial stent implantation surgery.

Objective To establish and evaluate the CaV1?1?R528H gene knock?in mouse model of thyrotoxic hy?pokalemic periodic paralysis. Methods Thirty?six 8?week?old male CaV1?1?R528H gene knock?in mice and thirty?six 8?week?old wild?type male C57BL/6J mice were used in this study. Using three?factor two?level 2 × 2 × 2 factorial design ( the three factors including mutation, thyroxine and insulin, and two levels were with or without) , the mice were divided into 8 groups. The thyroxine groups were intraperitoneally injected with levothyroxine in a dose of 350 μg/kg once per day for 12 consecutive days to produce thyrotoxicosis. The insulin groups were intraperitoneally injected with short?acting insulin in a dose of 0?8 U/kg after the last administration of levothyroxine, and the potassium levels of different groups were meas?ured and recorded before (0 min) and after insulin injection (30 min, 60 min). Results (1) Compared with the control group, the following phenomena including irritability, dull coat, increased diet and water intake, and slow body weight gain, were observed in the thyrotoxic mice. Thyroid function tests showed that the levels of T3 and T4 in the thyrotoxic mice were significantly higher than those in the corresponding control mice (P<0?05), and the TSH level was significantly low?er than that of the corresponding control mice (P<0?05 ). (2) After administration of insulin or thyroxine alone, the po?tassium levels in the mutant and wild?type mice were not significantly different. However, after combined administration of thyroxine and insulin, the potassium levels in the mutant group were significantly lower than those in the wild?type mice at 30 min and 60 min ( P<0?05 for both). (3) The main effects and interactions:Mutation factor or thyroxine factor alone did not influence on the potassium level, only insulin showed hypokalemic effect (P<0?05). There were interactions be?tween thyroxine and mutation, and between insulin and mutation (P<0?05), but no interaction between thyroxine and in?sulin. Conclusions (1) A thyrotoxicosis state in mice is successfully developed in this study. (2) An CaV1?1?R528H gene knock?in mouse model of thyrotoxic hypokalemic periodic paralysis is successfully established.

Methods Whole bone marrow adherent was used to screen, culture, and isolate BMSCs. Extracts from different parts (water, chloroform, ethyl acetate and n-butanol parts) of JPHGF were administrated for a certain time. MTS was used to detent cell proliferation;ALP staining was used to detect ALP activity;ARS staining was used to detect the formation of calcium nodules;oil red O staining was used to detect fat cell formation. Results Extracts from different parts of JPHGF could promote cell proliferation of BMSCs in different levels, followed by its strength in water, chloroform, ethyl acetate, and n-butanol parts;ALP staining results showed that the intensity of ALP expression of the order is water, acetic acid ethyl, chloroform and n-butanol parts;in promoting the formation of calcium nodules, ARS staining results showed that its intensity were water, chloroform, ethyl acetate, and n-butanol parts;oil red O staining results showed that inhibition intensity of fat cells interaction strength was formed from ethyl acetate, water, chloroform to n-butanol parts. Conclusion Extracts from different parts of JPHGF have different effects on BMSCs proliferation and differentiation. Water extraction has the strongest osteogenic differentiation and proliferation, and ethyl acetate has the best effect on the inhibition of cell formation.

Objective To explore the effect of entire process nursing intervention during nebulization treatment of acute wheezing episodes in school-age children.Methods One hundred and forty-one children with acute wheezing episodes were divided into the experimental group (75 patients) and the control group (66 patients) by whether willing to accept nursing intervention or not,respectively.Routine nursing such as cognition of wheezing knowledge and respiration instruction was given to both groups,while specialists accompanied the whole procedure of inhalation treatment and they gave nursing intervention such as respiration,saliva swallow,expiration through nose,grasp of inhalation tank and body position maintenance to the experimental group.The improvement of wheezing and subjective sense by the patients,transcutaneous oxygen saturation (SaO_2),and the compliance of patients were measured and evaluated.Results Improvement of wheezing and comfort feeling were found in 97.3% of the experimental group,while 80.3% of the control group.And SaO_2 value (higher than 95%) was 92.0% in the experimental group,75.8% in the control group.The compliance of the experimental group was also better than the control group.Conclusions Entire process nursing intervention during nebulization treatment can improve clinical effect and the compliance of wheezing children.

Objective To establish a model for preparation of tissue-engineered skin grafts with hTERT cells carrying human papillomavirus type 6 (HPV 6) genome in vitro, so as to lay a foundation for studying HPV life cycle. Methods The full-length linear HPV6 genome and plasmid pEGFP-▲EGFP were electrophoretically cotransferred into hTERT cells. After selection using G418 resistance, Southern blotting was performed to determine the viral load of HPV6 in transfected cells. 3T3 J2 trophoblastic cells, type I rat-tail collagen and hTERT cells containing the full-length HPV6 genes (HPV6.hTERT cells)were mixed and cocultured on metal meshes to form skin graft-like structures. Hematoxylin and eosin (HE)staining was performed to observe the structure of formed skin grafts, an immunohistochemical assay to measure the expression of HPV6 L1 protein, and electron microscopy to observe virus particles in the skin grafts. Results The linear HPV6 gene was successfully transferred into hTERT cells, and Southern blotting showed the presence of HPV6 DNA in the transferred hTERT cells. The HPV6.hTERT cells, which were cocultured with 3T3 J2 trophoblastic cells and type I rat-tail collagen, proliferated and differentiated over time, and gradually formed skin grafts giving the appearance of verrucous hyperplasia. HE staining showed that the cocultured HPV6.hTERT cells could form typical stratified structure of skin after 7 days of cultivation, and histopathologic features of HPV infection, including obvious papillomatous hyperplasia, presence of vesicular cells, hyperkeratosis and parakeratosis, could be observed after 21 days. The immunohistochemical assay showed the expression of HPV6 L1 protein in the upper portion of skin grafts, and electron microscopy revealed the presence of HPV6 virus particles in skin grafts. Conclusions The established model for preparation of tissue-engineered skin grafts using HPV 6 genome-carrying cells provides a basis for biological studies of HPV, but its application is limited to some degree.
