Objective To analyze the prevalence of nosocomial infections among inpatients and its influential factors.Methods The retrospective survey was performed by reviewing and analyzing the clinical data of 7788 inpatients in 2004 in Nankai Hospital of Tianjin.Results Totally 250 nosocomial infection cases were identified,which gave a prevalence of 3.21%.The all-year highest prevalence was found in September.Among all the departments,the highest rate,5.20%,occurred in Department of Gynecology.The inpatients aged more than 60-year-old showed higher prevalence than those under 60 years old.The main infection position was lower respiratory tract(41.60%).Concludes The prevalence of nosocomial infections of Nankai Hospital were within the acceptable standard range defined by Ministry of Health,China.Nevertheless,the prevalence would be reduced if measurements for surveillance and control could be properly applied.

Objective: To express glycosyl-phosphatidylinositol (GPI) modified Met- RANTES fusion protein on Chinese hamster ovary (CHO) cells and to develop a novel immunosuppressant GPI anchored form of Met-RANTES. Methods: The eukaryotic expression vector PEF/GPI-Met-RANTES were constructed and transfected into CHO cells by electroporation. The transfectants were selected with methotrexate (MTX). Expression of the recombinant protein was assessed by flow cytometric analysis, cell immunofluorescence staining and immunogold electron microscopy. Results: The chimeric molecules of GPI anchored form of Met-RANTES including the whole reading frame were constructed, and the sequence was identical to the designed sequence. GPI anchored form of Met-RANTES was stably expressed on CHO- DHFR- cells. Conclusion: A large amount of GPI modified Met-RANTES fusion protein was expressed on CHO cells. GPI anchored form of Met-RANTES may be used as novel immunosuppressant for suppressing reaction in graft rejection.

Objective To explore the technique outcome of fixing the ventral stress pedicle screws into the injured vertebrae, as a method to enhance the posterior internal fixation. Methods From March 2002 to March 2005, 33 single thoracolumbar fractures were studied retrospectively. Among which, 16 cases were treated with the above method(group A), and the other 17 were treated with traditional two-level fixation(group B). Group A involved 11 males and 5 females, aged 48 years averagely(range, 32-74 years); and group B included 12 males and 5 females, aged from 21 to 61 years(mean, 40 years). All the patients underwent the operation within up to 3 weeks after fracture. For the injured vertebral bodies, their pedicles were intact on either unilateral or bilateral side, and their lower half and endplate were free from split. In group A, the pedicle screws in the injured vertebrae were used to achieve the ventral press vertical to the distraction for the stress neutralization, and also with the routine distraction and lordosis restoration, simultaneously. The mean follow-up period was 11 months with a range from 6 to 24 months. Results After operation, the optimal Cobb angle and anterior column restoration were achieved through the ventral reduction from the injured vertebral body, which was the contribution from the vertical stress pedicle screw. The degree in anterior movement of injured vertebrae pre- and postoperatively was much more in group A than group B, and the difference was of statistical significance(P

Objective To investigate the correlation between the expression of CD147 and MUC5ac in peripheral small cell lung cancer and the computed tomography (CT) signs.Methods Forty two cases of peripheral non-small cell lung cancer (NSCLC) confirmed by operation and pathology were examined by CT.The positive expression of CD147 and MUC5ac was detected by immunohistochemical staining and the relationship between the expression of CD147 and MUC5ac was analyzed.Results CD147 and MUC5ac were closely related to the lymphatic metastasis of peripheral non-small cell lung cancer (P ＜ 0.05).The positive expression of CD147 is significantly related to tumor size,deep lobulation,spinous process and lymphadenopathy (P ＜ 0.05).MUC5ac is significantly related to tumor size,deep lobulation,spiculation,vascular convergence sign,extrapleural fat Line disappearance,and mediastinal lymphadenopathy (P ＜0.05).Conclusions These results indicate that CD147 and MUC5ac play an important role in the invasion and metastasis of peripheral lung cancer.

Objective To investigate the preventive effects of anti-viral therapy in combination with transcatheter arteria chemoembolization (TACE) on recurrence of HBV-related hepatocellular carcinoma (HCC) after operation. Methods According to selection standards, 49 patients treated in this hospital from January 2003 to June 2009 were enrolled in this study and divided into a control group and combined group.The cumulative tumor-free survival rate, cumulative survival rate, the 1-, 2- and 3-year recurrence rates and cumulative recurrence rates were determined in all the patients and compared between the 2 groups. Results The cumulative tumor-free survival rate and cumulative survival rate were significantly higher in the combined group than in the control group (P=0. 019, 0. 008). The 1-, 2-, and 3-recurrence rates were 24% vs. 38.9%, 28% vs. 33.3%, and 28% vs. 22.2% in the combined group and control group, respectively. The 1-, 2-, and 3-year cumulative recurrence rates were 24% vs. 38. 9%, 52% vs. 72. 2%, and 80% vs.94. 4% in the combined group and control group, respectively. Conclusion Anti-viral therapy in combination with TACE can exert significant preventive effects on recurrence of HBV-related HCC after operation.

Objective To evaluate the feasibility and effectiveness of full-size three-dimensional individual printed model (3D-IPM) for improving the patient's understanding of laparoscopic partial nephrectomy (LPN) preoperatively.Methods Between June 2015 and June 2016,37 patients with cT1 renal tumors underwent retroperitoneal LPN.The 3D individual digital models (3D-IDMs) were created using 3D medical image reconstructing and guiding system (3D-MIRGS) and the full-size 3D-IPMs were fabricated correspondingly.For each patient and his/her closest accompanying immediate family member (CAIFM),two preoperative conversations with a single surgeon were held by using patient's CT films,the entity of 3D-IPM combined with 3D-IDM demonstration separately.The preoperative levels of comprehension to the renal anatomy,mass characteristics,the upcoming PN procedure,potential complication risks and postoperative prognosis were evaluated using a self-made scoring questionnaire in the patient and CAIFM groups.Results All the fabrications of full-size 3D-IPMs were technically successful.Both in patient and CAIFM groups,the total preoperative comprehending score (total-PCS) elevated significantly by presenting 3D-IPM combined with 3D-IDM demonstration than CT films (42.7 vs.31.5 in patient group,P ＜ 0.05;44.6 vs.33.1 in CAIFM group,P ＜ 0.05).Sub-PCSs in all 5 aspects also showed a uniformed climbing pattern with the assistance of 3D-IPM combined with 3D-IDM demonstration rather than CT films.Conclusion The application of 3D-IPM combined with 3D-IDM demonstration can improve the preoperative comprehension of the patient and CAIFM to LPN with more intuitionistic and verisimilar presentation.

Objective To explore the effect of age on neurogenesis of dentate gyrus granule cell and the impact on differentiation of newborn cells in rats.Methods SD rats were selected and divided into 5 groups according age of 7,14,28,60,180 d(n=8),and the neurogenesis of dentate gyrus granule cell in hippocampus with normal development was detected,using 5-bromo-BrdU(BrdU) labled newborn neuron and ?-tubulin protein(TuJ1) and glial fibrillary acidic protein(GFAP) labeled glial cells,and understood the newborn cells to neurons and glial cell differentiation ratio.Results Neurogenesis was found in dentate gyrus granule cell layer with hippocampus of all different age rats.Various forms of cells with a larger nucleus that were round,oval,diamond were distributed over the entire granule cell layer.BrdU-positive cells within each group were 158.07?5.37,141.28?7.27,116.93?9.24,76.56?6.88,41.42?4.45,the number of BrdU-positive cells were reduced with the growth of rats(P0.05);4%-5% newborn cells expressed GFAP.In addition,some of the BrdU-positive cells at the same time did not express TuJ1 or GFAP.Conclusions There are neurogenesis in dentate gyrus granule cell in rats of different age.The new born cells mostly differentzate into granule neuron cell.The capability of cell proliferation are decreased with the growth of age.

Objective To evaluate the efficacy and safety of intravenous itraconazole followed by itraconazole capsule.Methods An open-label,randomized,non-controlled study was conducted.Itraconazole was administered intravenously at a dose of 200 mg,q12h for the first 2 days,then once daily from the 3rd to the 14th day and followed by itraconazole capsule,200 mg,q12h for 2 to 4 weeks.Results A total of 25 patients were enrolled in the study,including 12 documented cases of invasive fungal in- fection,11 probable cases and 2 possible cases.Twenty-two patients were eligible for clinical efficacy analysis,of which 11 were cured,4 significant improved,2 improved and 5 failed.The effective rate was 68.2%(15/22),and the cure rate was 50.0%(11/22).Twenty-four strains of fungus were obtained,including 22 strains of Candida spp.and one each of Aspergil- lus and Histoplasma capsulatum.Eighteen strains of fungus were eradicated after itraconazole treatment.The eradication rate was 75.0%(18/24).In the 25 cases who received at least one dose of intravenous itraconazole,itraconazole-related or proba- bly-related clinical adverse event was reported in 3 patients,including drug fever,chest discomfort,palpitation and decreased appetite,Itraconazole-related or probably-related laboratory abnormality was reported in 4 cases.AST or ALT elevation was the most common laboratory abnormality.One patient was found to have increased blood creatinine,BUN and hemolysis.Most adverse effects were mild and tolerable except one serious adverse effect.Conclusions Intravenous itraconazole followed by itraconazole capsule therapy has good efficacy in the treatment of systematic fungal infection.The regimen is well-tolerated in most patients.

To make a systematic analysis on literatures concerning traditional Chinese medicine (TCM) advices in Treatise on Febrile Diseases, and summarize the main connotations of traditional Chinese medicine advices, relevant TCM advices in Treatise on Febrile Diseases were collected, screened, compared, summarized and analyzed according to TCM dosage form preparation methods, TCM administration methods, medication contraindications and nursing after TCM administration. The literatures concerning medications in Treatise on Febrile Diseases were consulted, summarized and compared to standardize medicine advices and facilitate rational clinical application of TCMs. The standard medicine advices were as follows. The boiling water for TCMs shall be tap water and well water. The decoctions that have effects in promoting blood and meridians can be boiled with wine. The decoctions containing toxic components can be boiled with honey. Some TCMs shall be boiled with special methods, e. g. Herba Ephedra that could be boiled before other medicine and skimmed. Japonica rice could be added in decoctions to measure the duration of decoctions. Different dosages were required for different forms (litre, pill, medicine spoon). Administration times, temperature and frequency shall be adjusted according to target positions, functions and stage of illness. As for dietary contraindications during medication, thick porridges are recommended, where foods impacting medicine efficacy are prohibited. Regarding nursing after medication is important to recover physical functions, particularly warm porridges can go with diaphoretic recipes, while thick porridges can go with purgative recipes. And drug efficacies shall be defined by observing urine and excrements, and blood form. In conclusion, Treatise on Febrile Diseases is the first book that discusses TCM advices and records them in details. In this study, new standard medicine advices were proposed to provide important basis for improving clinical advices of TCMs and supports for developing the TCM dispensing technology.
