Objective To investigate prevention and treatment of parastomal hernia. Methods Clinical data of parastomal hernia of 44 cases were analyzed respectively with special respect to clinical features and repair methods. Result Simple sutures were used in 23 cases, mesh repair in 16 cases, stoma relocation plus mesh repair in 5 cases. Postoperative recovery was satisfactory in 39 cases. Incisional infection occurred in 5 cases, and hernia recurrence developed in 3 cases (6.8%) during a follow-up of 6 to 108 months (average 49 months) in 41 patients. Conclusion The causes of parastomal hernia are miscellaneous especially incisional infection; Perioperative malnutrition must be corrected companying diseases properly controlled, and operative technique improved to prevent the incidence of parastomal hernia; Surgery is the only cure for parastomal hernia. Mesh repair and/or stoma relocation is sometimes necessary.

Objective To evaluate the therapeutic effect of acupoint catgut embedding on gastrointestinal dysfunction after surgery in patients with severe traumatic brain injury.Methods Sixty-eight consecutively hospitalized patients with gastrointestinal dysfunction after surgery in patients with severe traumatic brain injury admitted to the Department of Intensive Care Unit (ICU) in the First Affiliated Hospital of Zhejiang University of Chinese Medicine from January 2015 to December 2015 were enrolled.Six of those patients were withdrawn from the course of observation,and actually only 62 patients entered the study.They were divided into an observation group (32 cases) and a control group (30 cases) by random number table.All the patients of two groups were given conventional treatment of western medicine for consecutive 7 days.The observation group was additionally treated with acupoint catgut embedding.The control group took mosapride tablets via a nasogastric tube 5 mg,3 times a day.Intra-abdominal pressure (IAP),gastric residual volume (GRV),time for reaching standard enteral nutrition,serum diamine oxidase(DAO),D-Lactate activity,incidence of hospital-acquired pneumonia (HAP),hospitalization days in ICU,28-day mortality and adverse reactions of acupoint catgut embedding were observed in the two groups.Results After treatment,the levels of IAP,DAO,D-lactic acid were lower than those before treatment,GRV was less than that before treatment in the two groups,and after treatment for 7 days the changes were more significant in the observation group [IAP (cmH2O,1 cmH2O =0.098 kPa):12.42±3.11 vs.17.70 ± 2.98,GRV (mL):129.54 ± 57.54 vs.242.91 ± 99.29,DAO (U/L):9.06± 2.84 vs.13.60 ± 7.16,D-Lactate (mg/L):16.47 ± 5.39 vs.26.29 ± 9.62,all P ＜ 0.01].Days of mechanical ventilation (days:6.97 ± 4.13 vs.9.23 ± 4.61),time for reaching standard enteral nutrition (days:4.25 ± 3.15 vs.5.50 ± 3.12) and hospitalization days in ICU (days:9.50± 4.03 vs.12.20 ± 6.38) in observation group were significantly shorter than those in control group (all P ＜ 0.05).The incidence of HAP [15.6％ (5/32) vs.40.0％ (12/30)] and 28-day mortality [3.1％ (1/32) vs.6.7％ (2/30)] in observation group were obviously lower than those in control group.The patients in observation group had no significant adverse reactions of acupoint catgut embedding.Conclusions Acupoint catgut embedding therapy is not only easy to operate,but also can effectively improve gastrointestinal motility and intestinal barrier function in patients with gastrointestinal dysfunction after surgery of severe head injury,thus it is beneficial to reaching the enteral nutritional goal in less time,reducing the incidence of HAP,shortening the hospitalization time in ICU and promoting the recovery of the patients.

The expression and possible role of integrin-focal adhesion kinase signal pathway in invasive pituitary adenomas were explored. Forty-nine human pituitary adenomas were detected for the expression of integrinbeta1 (INTbeta1) and focal adhesion kinase (FAK) by immunohistochemistry, and their correlation with the invasiveness of pituitary adenomas as well as between themselves was analyzed. The results showed that INTbeta1 was expressed in 46 cases (93.9%) and FAK in 36 cases (73.5%), respectively, and their expression levels were highly correlated with tumor invasiveness, but not with the tumor types. It was suggested that the integrin-focal adhesion kinase signal pathway plays a role in the invasiveness of pituitary adenomas.

Objective To explore the inhibition effect of interleukin-10(IL-10)on pneumonic anaphylacticitis in mice with asthma and its effects on the level of serum IgE.Methods Thirty BALB/c male mice whose weight were(20?2)g were randomly divided into 3 groups:normal group(n=10),asthma model group(n=10)and IL-10 treatment group(n=10).Asthma model group and IL-10 group were sensitized with 1 g?L-1 ovalbumin,then asthma model was made with inhallating 10 g?L-1 VOA 20 mL.The normal group was not administered anything as a negative group.Before inhallating with 10 g?L-1 VOA,asthma model group was administered inhalation with 9 g?L-1 saline 0.1 mL,and IL-10 treatment group was administered inhalation with 0.1 mL IL-10 whose concentration was 0.2 ?g?L-1.The level of IgE was measured by ELISA reagent box,eviscerated lungs after collecting blood and then made them into pathological slices.Results There was an obvious distinction in the mice pathological change of lungs and bronchus between asthma model group and other groups,but no significant difference between IL-10 treatment group and normal group.There was no obvious infiltration of inflammatory cells in the airways of IL-10 treatment group and normal group.However,there were a great number of inflammatory cells in the interstitial and peribronchovascular regions of asthma model group.The levels of serum IgE were(5.219?0.427)?g?L-1,(6.633?0.145)?g?L-1 and(5.503?0.566)?g?L-1 in normal group,asthma model group and IL-10 treatment group,respectively.The level of serum IgE in asthma model group increased obviously compared with normal group and IL-10 treatment group,with significant differences(Pa0.05).Conclusions Inhalation of IL-10 can optimally control the pneumonic anaphylacticitis,improve the situation of airway inflammation in mice asthmatic model and reduce the IgE serum level.

Urokinase plasminogen activator receptor (uPAR) is a membrane protein which is attached to the cellular external membrane. The uPAR expression can be observed both in tumor cells and in tumor-associated stromal cells. Thus, in the present study, the human amino-terminal fragment (hATF), as a targeting element to uPAR, is used to conjugate to the surface of superparamagnetic iron nanoparticle (SPIO). Flowcytometry was used to examine the uPAR expression in different tumor cell lines. The specificity of hATF-SPIO was verified by Prussian blue stain and cell phantom test. The imaging properties of hATF-SPIO were confirmed in vivo magnetic resonance imaging (MRI) of uPAR-elevated colon tumor. Finally, the distribution of hATF-SPIO in tumor tissue was confirmed by pathological staining. Results showed that the three cells in which we screened, presented different expression characteristics, i. e., Hela cells strongly expressed uPAR, HT29 cells moderately expressed uPAR, but Lovo cells didn't express uPAR. In vitro, after incubating with Hela cells, hATF-SPIO could specifically combined to and be subsequently internalized by uPAR positive cells, which could be observed via Prussian blue staining. Meanwhile T2WI signal intensity of Hela cells, after incubation with targeted probe, significantly decreased, and otherwise no obvious changes in Lovo cells both by Prussian blue staining and MRI scans. In vivo, hATF-SPIO could be systematically delivered to HT29 xenograft and accumulated in the tumor tissue which was confirmed by Prussian Blue stain compared to Lovo xenografts. Twenty-four hours after injection of targeting probe, the signal intensity of HT29 xenografts was lower than Lovo ones which was statistically significant. This targeting nanoparticles enabled not only in vitro specifically combining to uPAR positive cells but also in vivo imaging of uPAR moderately elevated colon cancer lesions.

Objective To evaluate the clinical application of serum CYFRA21-1 detection during the diagnosis of lung cancer. Methods Serum level of CYFRA21-1 in 196 patients with lung cancer and 39 healthy controls were determined by the Elctro-chemiluminescence Immuno-assay ( ECLIA) , respectively. Results Serum level of CYFRA21 -1 ( range from 0. 30 μgg/L to 500.00 μg/L) in patients with lung cancer were significantly higher than those in the healthy control ( range from 0. 27 μg/L to 3. 29 μg/L,Z = -4. 65,P < 0.01). ROC analysis of diagnosis efficiency showed that the area under curve ( AUC) was 0. 735 (P < 0. 001 ). The confidence interval of 95% was from 0. 663 to 0. 807. Positive detection rate of CYFRA21-1 was 48. 8% (39/80) in squamous,31.7% (20/63) in adenocarcinoma and 22. 6% (12/53) in small cell lung cancer (SCLC) respectively, as well as total positive rate was 36. 2% (71/196). Stepwise regression analysis showed that serum level of CYFRA21-1 had a linear correlation with the squamous and the metastasis to liver or bone (r =0. 505 ,P <0. 05). Conclusions Serum level of CYFRA21-1 increases the diagnostic sensitivity, which is helpful for determining histological types, monitoring the metastasis of liver and bone, and evaluating the treatment response in patients with lung cancer.

Objective To investigate the effects of cryopreservation on the growth and osteogenesis capa- bility of human bone marrow stromal cells(BMSCs)on demineralized bene matrix(DBM).Methods Bone marrow aspirates were obtained from the lilac crests of three donors.The BMSCs were isolated from the bone marrow by density gradient centrifugation.Cells of passage 3 were cryopreserved in liquid nitrogen for 24 hours,and then re- covered.The non-cryopreserved BMSCs were used as the control,The cryopreserved and control BMSCs were cul- tured in osteogenic media,collected and labeled with Dil to be seeded onto the DBM when cells were confluent.The percentage of BMSCs adhered to the DMB was detected.The cell morphology and matrices secreted by BMSCs on the DBM were observed by the inverted phase-contrasted microscope,fluorescence microscope and scanning electron microscope(SEM).The growth and viability of BMSCs on the DBM were determined using the modified MTT ashy. The osteogenesis ability of BMSCs on the DBM was determined by assessment of the alkaline phosphatase(ALP) activity and osteocalcin(OCN)content.Results The percentages of the cryopreserved and control cells adhered to DBM were(97.25?1.17)% and(97.00?1.09)% respectively.The cells adhered well to the DBM and grew rapidly.Large amounts of matrices on the DBM were observed by the light microscope and SEM.The cells embedded in the matrices could be observed by fluorescence microscope.There were no significant differences in the assay values of MTT,ALP and OCN between the cryopreserved and control BMSCs on the DBM.Conclusion Since cryopreservation does not affect the growth and osteogenesis capability of BMSCs on DBM,the cryopreserved BMSCs can be used as a cell source in bone tissue engineering.

OBJECTIVE To investigate the HIV infections states in tumor patients for clinical diagnosis,treatment and to prevent HIV infection in the tumor hospital.METHODS The result of HIV detection in tumor patients from Dec 2000 to Aug 2006 was analyzed by the review statistics analysis.RESULTS Totally 48 101 tumor paients were detected,and the number of tumor patients with positive HIV antibody result was 51(0.106%).Among the positive patients there were 21 cases with blood transfusion history,14 cases with blood donating experience,2 cases with both these two kinds of experiences and 14 cases without the two kinds of experiences.Their rate was separately 41.0%,27.5%,4.0% and 27.5%.Most of the HIV positive patients had no clinical synptoms.CONCLUSIONS The HIV positive rate of patients with blood transfusion or blood donating is significantly higher than the patients without these experiences.The routine detection for the HIV before the operation,blood transfusion or other traumatic detection is very necessary.

AIM: To make a contrast and then analyze the difference of optical coherence tomography (OCT) before and after vitreomacular traction syndrome (VTS) was performed.METHODS: The clinical date of 11 evaluable eyes of 11 patients with VTS who were diagnosed by OCT and underwent 25G vitreous surgery from January 2013 to January 2014 were retrospectively analyzed.Patients were followed up for an average of 6mo, to observe the visual acuity and OCT examination of the patient before and after operation.We compared the changes of retinal thickness and local morphology before and after operation.RESULTS: After vitreous retraction, 6 eyes improved, 2 eyes do not improve.One eye received macular membrane traction, in the operation the macular epiretinal membrane peeling, retrial membrane stripping and the triamcinolone acetonide intravitreal injection were given, but after the operation, the vision does not improve.Two eyes received vitreous combined with retinal macular membrane traction.In the operation, macular epiretinal membrane stripping was given, after the operation, visual acuity improved.The proportion of those with visual acuity of 0.1 or more increased from 46% before to 73% after the operation.Before operations, the mean central macular thickness was 619.27±195.13μm, 239.12±143.84μm after, which decreased significantly (P<0.05).CONCLUSION: Vitrectomy can effectively relieve the vitreous traction of the macula, and can prevent further decline in visual acuity and reduce macular edema as well as improve the visual acuity of some patients.So, OCT has important guiding significance on the diagnosis and prognosis of this group.
