Tianjin Medical Journal 2015;(6):656-658,708
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 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.

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.

Objective To elevate accuracy of CT T4 staging diagnosis of esophageal carcinoma, we analysed relativity between CT diagnosis and postoperational pathology for the tracheal, bronchial, carinate early invasion. Methods From 1996 to 2002, 49 patients with cervical and middle-upper segment esophageal carcinoma proved by esophagectomy and pathology, whom were taken cervical or thoracic CT scaning before operation. Comparison was studied between postoperational pathology and CT diagnosis of tumor early invasion of the trachea, bronchus and carina. Results Of 49 patients with esophageal carcinoma, 21 lesions were in the cervical esophagus, out of 18 cases with tracheal early invasion performed by CT scaning, 14 cases comfirmed by postoperational pathology; 28 lesions in the middle-upper segment of thoracic esophagus, out of 17 cases with tracheal, bronchial or carinate early invasion diagnosed by CT scaning, 14 cases testified by postoperational pathology. Tracheal, bronchial and carinate early invasion of esophageal carcinoma proved by CT did not accord with postoperational pathology completely. The sensitivity, specificity, and accuracy of CT diagnosis for the tracheal, bronchial and carinate early invasion of esophageal carcinoma were 93.3 %, 33.3 %, 76.2 % in cervical esophageal and 82.4 %, 72.7 %, 78.6 % in thoracic esophageal respectively. The contingency coefficients of preoperational CT scaning comparison with postoperational pathology are 0.52, 0.77 respectively. Conclusion Early invasion to the trachea, bronchus and carina identified by conventional CT procedure for patients with esophageal cancer was more accurate and specific in thoracic than that in cervical. Esophageal tumor early invasion to the trachea, bronchus and carina performed with CT corresponded to postoperational pathology in some measure. Operatablity did not completely depend on the invasion of the trachea, bronchus and carina of esophageal carcinoma performed with CT.
