Objective Investigate the clinical efficacy of treating retreated smear-positive tuberculosis patients with conventional anti-tuberculosis chemotherapy combined with levofloxacin. Methods Divide 60 retreated smear-positive tuberculosis patients registered in our hospital between October 2012 and October 2014 into two groups using random number table method: levofloxacin group and conventional treatment group. Each group contains 30 patients that were treated for 9 months , and the efficacy the both treatment methods were compared. Results The sputum conversion rate in the levofloxacin group is 93.33% and 96.67% after treating for 6 months and 9 months , respectively; which are substantial higher than that of the conventional treatment group with sputum conversion rate of 70% and 73.33% after 6 months and 9 months of treatment , respectively (P < 0.05). The absorption rate of the levofloxacin group is significantly higher than that of the conventional treatment group (P < 0.05). The cavity improvement rate of the levofloxacin group is 73.33%, which is significantly higher than that of the conventional treatment group (33.33%) (P < 0.05). The clinical efficacy of the LVFX group is substantially higher than the routine treatment group (P < 0.05). The overall effectiveness of LVFX group reached 100% , which is significantly higher than that of the conventional treatment group (86.67%) (P < 0.05). Conclusions Levofloxacin combined with conventional anti-tuberculosis chemotherapy can effectively improve the clinical efficacy in the treatment of tuberculosis.

OBJECTIVE:To study the advantage of microwave technology in the preparation of plastic beads. METHODS:Three kinds of representative processing methods were applied to prepare Equus asinus,Colla Cornus Cervi and Colla Carapax et Plastri Testudinis. The processing methods and the quality of plastic beads were compared. RESULTS:Study results showed mic-rowave technology was superior to other processing methods in the preparation of plastic beads and quality. CONCLUSION:The microwave technology has its specific advantages in the preparation of plastic beads.

AlM:To investigate the features on prolonged central serous chorioretinopathy ( CSCR ) by optical coherent tomography ( OCT ) and to provide the basis of deciding the pathogenetic condition and prognosis. METHODS: Eighty - five patients who had been diagnosed with CSCR were grouped by suffering time as below: 32 patients suffered longer than 6mo as the prolonged and 53 patients with CSCR cured within that time. The imaging features of OCT were compared between the above groups.RESULTS:The incidence rate of neuroepithelial serous detachment extent above 500μm associated with pigmentary epithelial detachment in suffering eye and pigmentary epithelial damage in contralateral eye was significantly different between two groups. However, the incidence rate of neuroepithelial serous detachment extent above 4 000μm was not significant difference.CONCLUSlON:OCT could display clearly the change of every layer of retina with simplicity and visibility, which supplies us a new horizon to diagnose and trace CSCR. We could decide the pathogenetic condition and prognosis in accordance with the features of OCT, to provide references for the diagnosis and treatment of CSCR.

Objective Due to redundant valuations and inaccurate quantities and specifications in processing temporary medical orders, expensive medicines, water and cream medications, program patches of electronic prescriptions included in the nurse work station were designed and developed. Methods Based on the software and hardware platforms of No.1 Military Medical Project, it was developed under Powerbuilder 9.0 without more tables and database expenses. Result Paperless prescription was realized. Conclusion The clinician's workload is reduced. Inaccurate patient expenses and drugs data are stopped.

OBJECTIVETo explore the effect of treatment of humeral supracondylar fracture with Kirschner and tension band wire fixation through small lateral incision.

METHODSFifty-eight patients of humeral supracondylar fractures included 42 males and 16 females with the average age of 9.4 years ranging from 3 to 65 years old. All patients were treated with Kirschner and tension band fixation through small lateral incision of 4 to 5 cm after reduction through lateral approach from the inter muscular space between the lateral of triceps brachii and the brachioradial muscle. Two Kirschner were insterted from the lateral condylars to humeral medial. Drill plumb on the humeral above fracture line distance 2 to 3 cm. A wire through bended on the lateral two Kirschners nails crossed in the shape of "8" figure.

RESULTSThe fracture obtained accurately reduction and rigidly fixation. All patients were followed up for 1 to 5 years (mean 2.4 years). According to Flynn clinical evaluation, the results were excellent in 48 cases, good in 6,fair in 3 and poor in 1.

CONCLUSIONThis method has advantages of minimal trauma, easy manipulation, less operative time, early exercises and rapid recovery for the treatment of humeral supracondylar fracture.

Various geometric shapes and structures self-assembled of amphiphilic lipids when present in an aqueous environment, as active delivery vehicles, are becoming one of focuses of drug delivery system. Lipid-based cubic liquid crystalline nanoparticles (or Cubosomes) consisting of "honeycombed (cavernous)" structure spontaneously formed when a certain concentration of amphiphilic lipids dispersed in aqueous solution has curved bicontinuous lipid bilayer in three dimensions, separating two congruent networks of water channels. Its unique structure consists of internal double water channels and large interfacial areas, which reveal great flexibility in encapsulation efficiency of various polarities and amount of drugs, and has variegated range of drugs encapsulated. As a drug delivery vehicle, high drug payloads, stabilization of peptides or proteins and simple preparation process are also its advantages. The ability of cubic phase to incorporate and control release of drugs of varying size and polar characteristics, and biodegradability of lipids make it an interesting drug delivery system for various routes of administration, including oral, topical (or mucosal) and intravenous administrations, with extensive application in a multitude of dosage forms. Furthermore, a number of different proteins in cubic phase appear to retain their native conformation and bioactivity, and are protected against chemical and physical inactivation. In this paper, investigations of lipid-based cubic liquid crystalline nanoparticles are reviewed and summarized, with a hope to provide a reference for its in-depth study. At the end, the authors made a development prospect of this novel excellent candidate for active ingredients delivery vehicle.
