This paper reported that a new type of floating osmotic pump of ambroxol hydrochloride was designed. Third method apparatus (Chinese Pharmacopeia 2010, appendix XD) was employed to simultaneously evaluate the release and floating behavior in vitro. The system was optimized using central composite design-response surface methodology. Similar factor (f2) between the release profile of self-made formulation and the target release profile was chosen as dependent factor. The amount of glucose (A, mg), pore former (B, %) and weight of coating (C, %) were employed as independent factors. Optimized formulation was: A (100.99 mg), B (1.70%), C (4.21%). The value of f2 (89.14) was higher than that of market capsules (69.02) and self-made tablets (72.15). It was showed that self-made capsules possessed character of zero-order release (r = 0.994 4) and drug release completely (>90%). It was showed in result of in vivo study that tmax and Cmax of self-made capsules were significantly lower than that of market capsules and self-made tablets. The correlation coefficient between the fraction of absorption in vivo and the release rate in vitro was 0.985 1, and relative bioequivalence of self-made capsules was 110.77%. Accordingly, self-made capsules displayed obviously characteristics of controlled release both in vivo and in vitro.

Objective:To evaluate the effect and safety of rifabutin combined with multi-drugs in the treatment of multi-drug resist-ant tuberculosis with long-term therapy. Methods:Totally 86 cases of patients with multi-drug resistant tuberculosis were divided into the control group and the treatment group with 43 ones in each according to a random number table method. The two groups were trea-ted with levofloxacin, pasiniazid, ethambutol, protionamide and amikacin etc. The control group was treated with rifapentine, and the treatment group was treated with rifabutin additionally. After 18-month treatment, the negative conversion ratio of sputum smear and sputum mycobacterium tuberculosis culture, lesion absorption rate and cavity closure rate of X-ray chest radiograph and adverse reac-tions in the two groups were compared. Results:The negative conversion ratio of sputum smear and sputum mycobacterium tuberculosis culture in the treatment group was 41. 86% and 32. 56%, respectively, which were similar with those in the control group ( P >0. 05). There were no significant differences in lesion absorption rate and cavity closure rate of X-ray chest radiograph and adverse re-actions between the two groups (P>0. 05). Conclusion:Rifapentine or rifabutin combined with multi-drugs in the treatment of multi-drug resistant tuberculosis can improve the negative conversion rate of sputum mycobacterium and lesion absorption and cavity closure with high safety.

Background and purpose:The application of intensity-modulated radiotherapy (IMRT) has improved the local control rate of nasopharyngeal carcinoma greatly, which changed the predictive value of T classiifca-tions of TNM staging system. This study aimed to validate the predictive effect of T classiifcations in the 7th Union for International Cancer Control (UICC) staging system and discuss the simpliifcation of T classiifcations.Methods:We retrospectively reviewed the clinical data of 641 primary nasopharyngeal carcinoma patients at our center from January 2007 to June 2011. We evaluated the predictive effect of T classiifcations by Kaplan-Meier method and Cox regression model.Results:The 5-year overall survival (OS), local relapse-free survival (LRFS), progression-free survival (PFS) and distant metastasis free survival (DMFS) were 85.4%, 88.5%, 78% and 87.1%, respectively. The 5-year OS of T1, T2, T3 and T4 categories were 91.6%, 85.3%, 90.1% and 76.5%, respectively; LRFS were 93%, 85.3%, 91.5% and 84.4%; PFS were 88.2%, 77.3%, 80.8% and 70.9%; DMFS were 95.1%, 88.9%, 88.2% and 81.3%, respectively. The difference in survival curves between T1, T2 and T3 were not signiifcant (P>0.05). However, several prognostic indexes were signiifcantly different between T4 and T1, T2, T3. We merged the T1, T2 and T3 classiifcations as new T1, and the T4 classiifcation as new T2. The 5-year OS of new T1 and T2 were 89.1% and 76.5% (P=0.001); LRFS were 90.1% and 84.4% (P=0.028); PFS were 81% and 70.9% (P=0.001); DMFS were 90.8% and 81.2% (P=0.002). The survival curves were substantially separated. The simpliifed T classiifcations had obvious advantages when separately analyzed in different N stages.Conclusion:In the era of IMRT, the predictive effect of T classiifcations of the 7th UICC staging system has diminished. The simpliifcation of T classiifcations can ift with the new treatment and provide a better surviv-al prediction.

Objective To examine the advanced oxidation protein products (AOPP) in patients with acute coronary syndrome(ACS) and discuss the relationship between oxidative stress with the development of atherosclero-sis(AS). Methods Plasma were collected in 59 acute myocardial infarction (AMI) patients including 35 patients underwent selective PCI,24 patients underwent emergency PCI,43 unstable angina pectoris(UA) patients and 10 non-coronary artery disease (non-CAD) patients. All cases underwent coronary angiography (CAG). Plasma was collected immediately,post-24 hours and post-48 hours after admission. AOPP was determined by measurements of absorbance (A) at 340 nm under acidic conditions via spectrophotometry. Results AOPP was (236.42±30.41) ( n = 35 ), ( 207.84±29.50 ) mmol/L ( n = 35 ), ( 227.79 ± 35.18 ) mmol/L ( n = 31 ) respectively immediately, post-24 hours and post-48 hours after admission in AMI ( selective PCI ), ( 239.95 ±39.94 ) mmol/L ( n = 43 ), (175.92 ±29.46) mmol/L(n =38) ,and (156.54 ±28.29) mmol/L(n =35) in UA group and (57.41 ± 13.60) mmol/L( n = 9 ), (56.11 + 11.90) mmol/L ( n = 10 ) and ( 61.75 ± 12.28 ) mmol/L ( n = 8 ) in non-CAD group. Compared with normal group ( without CAD ) , significantly higher plasma AOPP was detected in AMI ( selective PCI) and UA patients ( P < 0.05 ). AOPP level was significantly increased in AMI selective PCI patients as compared with that of emergency PCI group immediately and post-24 hours after admission( P <0.01 ) ,and post-48 hours after admission( P < 0.05 ), but there was no statistical significance between emergency PCI and UA group( P > 0.05 ). Conclusions Oxidative stress is an important step in the development of atherosclerosis, and the higher levels of AOPP in ACS patients show that AOPP may be as good markers in these patients.

BACKGROUND: Oxfordshire Community Stroke Project(OCSP) is a new type of clinical classification for subdividing cerebral infarction(CI) conducted on the basis of a large-scale of investigation of stroke in the population of Oxfordshire Community, England in 1991. This kind of classification completely bases on the clinical manifestations without the help of diagnostic instruments, which can predict site and size of the lesion and the involved vessels.OBJECTIVE: To acknowledge the clinical classification of CI patients with Bamford's OCSP and its significance in predicting their long-term functional prognosis.DESIGN: Clinical observation, comparison and verified study based on patients.SETTING: Neurological department in a university hospital.PARTICIPANTS: Between January 1st and December 31st 2001, totally 126 patients with cerebrovascular disease were hospitalized in the Neurological Department of First Affiliated Hospital of Xi' an Jiaotong University,including 82 males and 44 females.METHODS: Totally 126 in-patients with CI were subdivided with Bamford's OCSP classification, and their disablity was assessed with Barthel index (BI)and modified Rankin Scale(mRS) when they were discharged and 3 months and 6 months later.MAIN OUTCOME MEASURES: Classification of patients with CI and their scores of BI and mRS when they were discharged and 3 months and 6months later.RESULTS: Of the 126 patients, 8(6. 3% ) patients were confirmed of total anterior circulation infarction (TACI), 29 (23. 0% ) of part anterior circulation infarction(PACI), 78(61.9% ) of lacunar infarction(LACI), 11(8.7%) of posterior circulation infarction(POCI) . They were followed-up for 6 months, and meanwhile 12 patients died. Of the other 114 cases the prognosis of TACI was the worst, while the prognosis of POCI and LACI was relatively better than that of PACI.CONCLUSION: CI is predominated by LACI. OCSP is effective for predicting long-term functional prognosis of patients with CI. But it is necessary to make multi-center prospective study on a much larger scale of samples of disease.

OBJECTIVE To study the best surgical technique for treatment of chronic hypertrophic rhinitis(HR).METHODS Eighty six cases with HR were divided randomly into 3 groups.Thirty cases were treated by transnasal endoscopic submucous inferior turbinate resection(group A),26 cases by partial inferior turbinectomy(group B)and 30 cases by bipolar radiofrequency ablation(group C).The epithelium of the inferior turbinate of the every case in 3 groups was examined with histomorphology and ultrastructure techniques at 6 months after operation. The efficacy and the features of in the 3 groups were compared.The MTR was determined in the patients of the 3 groups.The histomorphology and ultrastructure of the inferior turbinate were observed at 6 months after operation.RESULTS All the cases with HR in 3 groups were followed up for 3 to 6 months after operation.Effective rates of group A,group B and group C were 100 %,100 % and 96.3 % respectively, while there was no significant difference among the three groups.Compared to the group B,surgical techniques applied in Group A and group C have more advantages because ultrastructure of inferior turbinate mucosal cilia and nasal mucociliary transport function were nearly normal at 3 to 6 months after operation. The advantages include operating easily,wound healing up fast.MTR between pre-and post-operation was significant difference in group B.Epithelial tissue remained intact in group A and group C,while epithelial tissue in group B was instead of fiber tissue at 6 months after operation.The ultrastructure of inferior turbinate mucosal cilia in group A and group C remained intact at 6 months after operation.CONCLUSION The transnasal endoscopic submucous inferior turbinate resection and bipolar radiofrequency ablation for treatment of chronic hypertrophy rhinitis are effective. Submucous minimally invasive surgery of the inferior turbinate deserves to be recommended.
