ABSTRACT
This paper introduced the management of focus drugs in Ningbo, and evaluated the preliminary results by comparing the changes in terms of the income of these drugs before and after the measures taken. More measures should be taken by establishing a unified drug catalogue, strengthening the assessment, carrying prescription comment and periodic notification. The pharmacists can play a leading role in clinical rational drug use. These efforts can serve for scientific control of the unreasonable growth of medical expenses.
ABSTRACT
Objective To report retrograde transposition of composite tissue flap pedicled with peroneal artery in the treatment of bone and soft tissue defects following calcaneal osteomyelitis.Methods During the period from January 2008 through January 2015,47 patients with bone and soft tissue defects following calcaneal osteomyelitis were treated by retrograde transposition of composite tissue flap pedicled with peroneal artery.They were 43 men and 4 women,aged from 24 to 67 years(average,43.6 years).After radical focus debridement,the areas of skin defect ranged from 2 cm × 2 cm to 5 cm× 5 cm and the bone defects ranged from 1.5 cm × 1.0 cm × 2.0 cm to 3.0 cm × 3.0 cm × 4.5 cm.Results All the 47 patients were followed up for 6 to 72 months (average,25.2 months).Relapse of osteomyelitis occurred in 2 cases but secondary bone graft was needed in none.All the patients recovered their walking function.The texture and color of the composite tissue flaps were similar to those of normal skin,without obvious swelling.The flaps appeared good and imposed no obstacle to wearing shoes.The ankles and hind feet of the patients scored from 58 to 91 points (average,76.6 points) according to the American Orthopaedic Foot and Ankle Society (AOFAS) evaluation system,giving 7 excellent,32 good and 8 fair cases.Hallux flexion contracture without skin ulcer was observed in 10 cases 6 months after surgery,necessitating no surgical intervention.Conclusion Retrograde transposition of composite tissue flap pedicled with peroneal artery can effectively treat bone and soft tissue defects following calcaneal osteomyelitis,leading to a low recurrence rate and good foot appearance.
ABSTRACT
OBJECTIVE:To establish a method for the content determination of zolpidem tartrate in microsamples of rat plas-ma. METHODS:Rats were given zolpidem tartrate solution 3 mg/kg intragastrically,and 0.2 ml blood sample were collected and isolated. 50 μl plasma was precipitated by methanol,and the supernatant was determined by HPLC-fluorescence combined with ex-ternal method. Agilent HC-C18 column was used with mobile phase consisted of 0.03 mol/L KH2PO4 solution(containing 0.2% tri-ethylamine)-methanol (33∶67,V/V) at flow rate of 1.0 ml/min. The excitation and emission wavelengths were 254 nm and 390 nm,respectively. The sample size was 20 μl. RESULTS:The linear ranges of zolpidem tartrate in plasma was 2-200 μg/L(r=0.999 7),and the limit of quantification was 2 μg/L. The method recoveries of zolpidem were (96.96 ± 1.35)%-(105.0 ± 5.36)%(RSD=2.20%-4.88%,n=5),and extraction recoveries were (79.72 ± 0.01)%-(80.77 ± 0.02)%(RSD=1.34%-3.90%,n=5). The intra-day and inter-day RSDs were 1.40%-5.10% and 3.22%-9.25%(n=5),respectively. CONCLUSIONS:The method is simple,sensitive and suitable for the content determination of zolpidem tartrate in microsamples of plasma.
ABSTRACT
Objective; To evaluate the reliability and reasonability of maxillofacial skin color match using the digital camera. Methods; The stability of the experimental light source was evaluated before establishing the color measurement. 122 volunteers aged from 22 to 32 years were recorded by a Canon EOS 20D digital camera in studio environment when the light source was stable. Photographs were taken under a set exposure parameters(f/4.5,1/25 s,custom white balance,ISO 800) and saved as JPEG format. The CIE L~* a~* b~* color values were obtained from the digital images using Adobe Photoshop7.0 after color correction. All data were analyzed using SPSS 10. 0. Results;The experimental light source was stable in 21 to 70 minutes. It was suitable for color measurement during this period. The color parameters of all tested maxillofacial skin were:L~*49～66,a~*7 - 18,b~*5 -22. Conclusion;The assessment of maxillofacial skin color depend on method of measurement and instrument. The method of maxillofacial skin color matching by digital camera seems reliable.
ABSTRACT
OBJECTIVE: To establish a method for the determination of nitrofurazone in nitrofurazone and zinc oxide liniment. METHODS: The content of nitrofurazone was determined by UV spectrophotometry. The solvent was water and the wavelength was 375nm. RESULTS: There was good linear relationship within the concentration range of 1.05～12.60?g?mL-1(r=0.999 8). The average recovery was 100.9%,RSD=0.07%. CONCLUSION: The method was sensitive, accurate, reliable, reproducible, and suitable for quality control of nitrofurazone in nitrofurazone and zinc oxide liniment.
ABSTRACT
[Objective] Explore the combination therapy to lumbar intervertebral disc protrusion on clinical efficacy.[Methods]Treat a total of 206 cases of lumbar intervertebral disc protrusion.All cases were diagnosed by CT location;Use automatic lumbar traction bed,manipulation and cheirapsis,Chinese Fomentation,intraspinal injection and intravenous drug delivery,with functional exercise.[Results] 192 cases of patients with follow-up,period 8 months,148 cases curable,32 cases markedly,improvement in 9 cases,3 cases invalid.The total effective rate 98.43%.[Conclusion] The comprehensive treatment of Chinese and western medicine will enable the majority of patients with lumbar intervertebral disc protrusion be more satisfied with the treatment effect.
ABSTRACT
Traditional Chinese herbal medicines have been used for treating various ailments since medicine be- gan.The belief that natural products are much safer than synthetic drugs has led to dramatic growth of herbal medi- cine usage.Like synthetic drugs,herbal preparations also have potential to cause adverse effects and drug interac- tions.In this paper,pharmacokinetic studies on herb- drug interactions are reviewed and discussed in order to promote usage of herbs rationally and safely.
