Objective To observe therapeutic effect of repairing nasal septum perforation with auto temporal fascia wrapping ethmoid perpendicular plate through endoscopic surgery. Methods Retrospective analysis of 50 cases of nasal septum perforation patient, among whom 30 cases were repaired by traditional surgery and 20 cases were repaired by sand?wich surgery. All patients were examine by CT scan and nasal irrigation therapy were also performed through nasal endosco?py to improves nasal mucosa situation. Endoscopic procedures were performed in the traditional surgical group under local anesthesia, and septum mucosa was separated and shifted to repair septal perforation. On the other hand, temporal fascia of more than 2 times the diameter of the perforation were isolated then, wrapped around the perforation through front line of na?sal incision after separating membrane of the nasal septum cartilage. Now,temporal fascia wrapping autologous ethmoid per?pendicular plates form a rigid verticalsandwich prosthesisand were inserted into perichondrium of septal to repair perfora?tion. Anti-infection and nasal moisturizing treatment were given after operation. Postoperative symptoms and the perfor?mance in follow-ups were recorded. Results Intraoperative blood loss (mL:3.6±1.2 vs 13.4±2.9), operative time (min:25.2± 6.3 vs 46.5 ±10.3), mucosal damage range (mm2:10.2±3.2 vs 20.5±5.3) and mucosal repair time postoperation (d:19.5±3.9 vs 30.2±3.1) were all less in sandwich group than those in traditional group (P<0.05). Successful rate in sandwich group is also higher than that in the traditional surgical group (90.00%vs 46.67%, χ2=9.780, P<0.01) . No recurrence was found during follow-up from 6 months to 1 year in both groups. Conclusion Application of autologous temporalis fascia wrapping per?pendicular plate of ethmoid bone to form a rigidsandwich prosthesisto repair nasal septal perforation by endoscopic sur?gery were effective. It can restore the normal anatomy of the nasal septum.

Objective To investigate the influence of Gallium on osteocyte ultrastructure in osteoporosis.Methods A total of 66 8-month old rats were anesthetized.Oophorectomies were taken in the osteoporosis group,and in the control group a piece of fat were taken instead.12 weeks later,8 rats in each group were sacrificed and the tibias upside were used to observe the model duplication.After the model duplication succeeded,the residual rats were separated into 3 groups randomly: the control group,the osteoporosis group raised normally in 12 weeks and the gallium nitrate therapy group,which were injected 1mg/kg gallium nitrate in the abdomen 3 times per week.Microscope was used to observe the bone form of decalcification sections.Transmission electron microscope was used to observe osteocyte form and internal structure.Results The osteocyte structures of control group and gallium nitrate therapy group were normal.The chromatins distributed symmetrical and nucleuses were oviform.Pyknosis was found in some osteocytes in osteoporosis group.There's few organell in osteoblast in control group.Collagen excretion was found.A lot of endoplasmic reticulums and an abundant of collagen excretion were found in osteoblasts in osteoporosis group.A lot of endoplasmic reticulums and mitochondria were found in osteoblasts in gallium nitrate therapy group.An abundant of collagen excretion was found,but less than osteoporosis group.Conclusion Gallium can alleviate the damage of osteocyte ultrastructure elicited by osteoporosis.

Objective To evaluate the effects of nasal non-Hodgkin′s lymphoma(N-NHL) treated with chemotherapy alone, radiotherapy alone, chemotherapy plus radiotherapy and autologous peripheral blood stem cell transplantation(APBSCT) combined with total body irradiation(TBI);and to analyze the impact factors of prognosis. Methods 135 patients were treated between 1980 and 2000. All were confirmed by histopathology as N-NHL, including 122 T cell in origin, 12 B cell and 1 NK cell in origin. The main radiotherapy portal was set in front of the nose with a spade-like protrusion, supplement with a portal next to the ear on one side or both sides. Combined portal in facial cervical area was first used when there was invasion of the oropharynx. The median dose to the nasal cavity was 56.0Gy with a range of 35.2 to 75.5Gy, with added 30Gy to the primary lesion in two patients. Six patients received TBI combined with APBSCT, with 8Gy in the TBI group. Chemotherapy, given before or during after radiotherapy or alone, consisted of 2-6 cycles of COP, COPP, COMP, CHOP or COBDP. Prognostic factors were analyzed with Cox model. Results The local control rate was 12%,69%,76% and 83% in chemotherapy alone, radiotherapy alone, chemotherapy plus radiotherapy and APBSCT combined with TBI, respectively(P=0.057).The 5-year survival rate was 9%,52%,63% and 83%,respectively(P=0.032). Multi-factor analysis showed that tumor extension and treatment methods were the most important prognostic factors besides Ann-Arbor stage, but gender, pathology, age and symptoms had little effect on prognosis .Conclusions Chemotherapy plus radiotherapy group achieves a better survival rate than radiotherapy alone. It is helpful to evaluate prognosis to make more detail subareas on basis of local extensions in Ann Arbor staging system.For some N-NHL patients with good financial condition, APBSCT combined with TBI is a good choice.

BACKGROUND: The inflammatory reaction occurs following implantation of cardiovascular stent with manifestations of the activation of blood coagulation system and dramatically increasing of inflammatory markers serum C-reactive protein. OBJECTIVE: To explore the changes of inflammatory reaction and C-reactive protein in coronary artery disease patients following cardiovascular stent implantation.METHODS: A computer-based online search of CNKI (1990/2009) and PubMed databases (1990/2009) was performed for related articles with the key words "cardiovascular stent, C-reactive protein" in Chinese and "cardiovascular stent on plasma, C-reactive protein" in English.RESULTS AND CONCLUSION: Based on the metal stents, drug-eluting stents can transfer the active drugs to the damaged vessels, release them into the vascular wall and inhibit the in-stent restenosis, Main drugs of anti-inflammatory drug-eluting stent include dexamethasone and methylprednisolone. Main drugs of anti-migratory and anti-proliferative drug-eluting stent includerapamycin, paclitaxel and actinomycin D. Main drugs of supporting intima concrescence stent include estradiol. Coronary artery stents implantation can induce and aggravate local inflammation reaction, which have important infection for vascular endodermis hyperplasia and restenosis occurrence. Some impressible index for inflammation reaction, such as levels of C-reactive protein,have predictive value for vascular events following the coronary artery stents implantation. A significant increase in plasma C-reactive protein after coronary stenting has been observed following stent implantation. Therefore, understanding of inflammatory reaction and C-reactive protein, as well as cytokine changes is important for preventing restenosis, early treatment of restenosis, as well as improving treatment effect.

Objective:To evaluate the reliability and validity of the Chinese version of Interpersonal Stress-Coping Inventory for Undergraduates(ISI).Methods:Totally 421 college students of 1～3 grades in two colleges of Anhui province were selected.They were asked to complete the ISI and Simplified Coping Style Questionnaire(SCSQ)at the same time to test the reliability and validity of ISI.Two weeks later,52 of them were retested to test the re-test reliability.Results:Cronbach α of the Chinese version of ISI was 0.79,re-test reliability was 0.87.ISI Scores were correlated with SCSQ scores(r=0.69).Exploratory factor analysis was applied to the data,and three subscales were derived:positive coping,negative coping,and dilution coping.The factor loadinps were 0.41～0.68.The explained variances were 14.82,14.10,and 7.06 respectively.Conclusion:The Chinese version of Interpersonal Stress-Coping Inventory has good psychometric quality and can be used in Chinese undergraduates of interpersonal stress coping research.

AIM To explore effects of policosanol on depressing cholesterol in hyperlipidemia rats and the correlated biochemistry mechanism. METHODS The rats were randomly divided into normal control, policosanol 4 mg·kg~(-1) prevention, hyperlipidemia model, policosanol 4, 6 and 8 mg·kg~(-1) and lovastatin positive control groups. The later 5 group rats were fed with high-cholesterol diets for 4 weeks in order to make hyperlipidemia model and beginning from the 5th week, in addition to the normal control and model groups, other groups were ig given policosanol or lovastatin once a day for 6 weeks, respectively, and policosanol protection group rats were ig given with policosanol 4 mg·kg~(-1) once a day for 10 weeks, together with high-cholesterol diets everyday. Total cholesterol(TC), triglycerides (TG), low density lipoprotein cholesterol (LDL-C) and high density lipoprotein cholesterol (HDL-C) concentrations in the serum and fecal bile acid (FBA) in the exrement were determined by auto-biochemistry analyzer. The activity of 3-hydroxy-3-methyl-glutaryl coenzyme A (HMG-CoA) reductase in hepatocellular microsomes was detected by ultraviolet spectrophotometric analysis and activity of low density lipoprotein receptor (LDL-R) in peripheral blood lymphocyte was detected by fluorescence labelled integrator method. RESULTS Compared with hyperlipemia model group, the levels of TC decreased (39.1%-46.4%), LDL-C decreased (66.6%-80.7%), and FBA increased (9.7%-19.0%), the activity of HMG-CoA reductase decreased （13.8%-23.6%）, and activity of LDL-R increased (27.5%-129.6%) in policosanol prevention, policosanol 4, 6 and 8 mg·kg~(-1) and lovastatin groups, respectively; HDL-C increased （12.2%-16.7%） in policosanol prevention and policosanol 8 mg·kg~(-1) groups; TG decreased in lovastatin group. CONCLUSION Policosanol has significant effects on decreasing cholesterol. The decreasing cholesterol mechanism should include: ① increasing FBA excretion; ② decreasing the activity of HMG-CoA reductase; ③ increasing activity of LDL-R.
