OBJECTIVE:To understand the situation of essential medicines and promote their rational use in our hospital. METHODS:The prescription variety and cost percentages of essential medicines in outpatient department in the two halves years of 2013 in our hospital(eye and ENT specialized hospitals)were compared;the medicines with forefront prescription kind percent-ages in eye and ENT departments were sorted and rankings in 4 quarters were compared. RESULTS:After the approval of the Na-tional Essential Medicine List(2012 edition),compared with the first half year of 2013,prescription variety and cost percentages of essential medicines in outpatient department in the second half year were significantly increased (P<0.01). Prescription variety and cost percentages of essential medicines in eye department in the second half year were significantly increased(P<0.01),in the top 20 prescription variety,totally 2 kinds were contained by the list 2012 edition and 3 were contained by the supplementary list of Shanghai(2012 edition). Compared with the first half year of 2013,prescription variety and cost percentages of essential medi-cines in ENT department in the second half year were significantly decreased(P<0.01),the cost percentage was significantly in-creased(P<0.01),in the top 20 prescription variety,totally 2 kinds were contained by the list 2012 edition and 3 were contained by the supplementary list of Shanghai (2012 edition). CONCLUSIONS:The prescription variety and cost percentages of essential medicines in our hospital show increase trend. Nevertheless,the non-essential medicines are still dominant and further improvement of essential medicines is still needed. Medicine variety and dosage forms of eye in ENT department are insufficient concluded in Es-sential Medicine List. Further adjustment of Essential Medicine List still needs more consideration for the medication characteristics in specialized hospital.

Objective To introduce a new computer-assisted external frame for osteotomy to correct complex tibial and fibular deformity.Methods From January 2012 to December 2013,15 patients with complex tibial and fibular deformity were treated with a computer-assisted external frame and related computer software for surgical correction.All were unilateral limb deformity,involving the left lower limb in 8 cases and the right lower limb in 7 cases.They were 8 males and 7 females,15 to 43 years of age (average,26.8 years).The deformity was caused by old osteomyelitis in 9 cases and trauma sequela in 6.The related angles,distances and rotations were measured on the postoperative radiographs of the lower limbs.The data were input into the software to calculate the daily adjustment lengths of the frame rods.Daily frame adjustments were conducted according to the data calculated.The frame was removed when expected results were achieved.The patients lived independently during the adjustment.Results The 15 patients were effectively followed up for 10 to 22 months (average,15 months).Frame fixation time averaged 8.4 months (from 5.5 to 13.1 months).The reunion time averaged 8.0 months (from 5.4 to 12.1 months).The hospitalization time averaged 2.4 months (from 2.0 to 2.8 months).In 10 cases of limb shortening,the shortening lengths averaged 0.5 cm (from 0 to 0.9 cm) after adjustment.In 12 cases of angulation deformity,the angulation averaged 3.3° (from 0° to 5.4°) after adjustment.In 5 cases of rotation deformity,the maximum internal rotation was 5° and the maximum external rotation 10° after correction,deviating from the normal values by 3.5° on average.In 6 cases of horizontal displacement,the displacements averaged 0.5 crn after correction.All patients were satisfactory with corrected lower limb alignment,improved symptoms and appearance,giving a subjective satisfaction rate of 100％.Conclusion Use of computer-assisted external frame in surgical correction of tibial and fibular deformity can achieve satisfactory outcomes in simple,accurate,standardized,minimally invasive manners.

AIM: To study the synergistic protective effect of picrosideII and NGF for the oxidative stress on PC12 cells induced by hydrogen peroxide (H2O2). METHODS: The fluorescent probe 6-carboxy-2',7'-dichlorodihydrofluorescein (CDCFH) was used to assess the intracellular reactiveoxygen species (ROS) level, and MTT assay, morphological observation as well aslactate dehydrogenase (LDH) leakage were conducted to measure cellular injury. RESULTS: The H2O2-induced cytotoxicity was significantly attenuated in the presence of picroside II (25 μg/mL) and NGF (2 ng/mL). Cultures with this combined treatment possessed decreased level of ROS while increased cell survival, as compared to that of picroside II or NGF alone-treated cells. Accordingly, it was concluded that their synergistic protective activities against oxidative stress in vitro were demonstrated in various aspects including reversing morphological changes, enhancingthe ability of cell proliferation and ROS scavenging. CONCLUSION: Such action supports the therapeutic potential of picroside II and NGF in treating nervous disorders based on their synergistic effect.

Objective To compare the efficacy and safety of thrombolysis and anticoagulant therapy for post-traumatic acute submassive pulmonary embolism (PE) in middle-aged and elderly patients.Methods Totally 45 patients with post-traumatic acute submassive pulmonary embolism in our hospital were selected.Patients were divided into thrombolysis group (n =22) and anticoagulation group (n=23) according to their conditions.Symptoms and signs,blood gas analysis,D-dimer,echocardiography,CT pulmonary angiography (CTPA) were performed before and after thrombolysis or anticoagulant therapy.Results There were no significant differences in clinical curative rate between thrombolysis group and anticoagulation group [95.5％ (21/22) vs.91.3％ (21/23),x2 =0.32,P＞0.05],and no case was found dead in both two groups.There was a significant difference in hemorrhage rate between thrombolysis group and anticoagulation group [27.3％ vs.4.3％,x2 =4.53,P ＜ 0.05].At 24 hours after thrombolysis or anticoagulant therapy,the improvement rate of dyspnea,PaO2 level was significantly higher and the pulmonary arterial pressure was significantly lower in thrombolysis group than in anticoagulation group [45.5％ (10/22) vs.17.4％ (4/23),(80.4±8.1) mm Hg vs.(73.6±9.3) mm Hg,(51.2±6.2) mm Hgvs.(60.3±5.7) mm Hg,respectively,all P＜0.05],and there were no statistical significances at other time points between the two groups.Conclusions The clinical curative rate and fatality rate are similar in thrombolysis group versus anticoagulation group.Hemorrhage rate is higher in thrombolysis group than in anticoagulation group.Thrombolysis can relieve dyspnea rapidly,reduce pulmonary artery pressure and make the embolized blood vessels recanalized.Patients with low bleeding risk in a critical condition are suggested to take thrombolysis therapy,while patients with high bleeding risk in a light condition are suggested to take anticoagulant therapy.

Objective To explore the value of the LigaSure vessel sealing in laparoscopic nephrectomy surgery. Methods Laparoscopic nephreetomies were performed in 41 cases from May 2004 to December 2006 by using LigaSure, including simple nephrectomies, radical nephrectomies and nephroureterectomies. The operative time, estimated blood loss, open conversion rate, duration of postoperative drainage, total amount of postoperative drainage, postoperative hospital day as well as complication rate were recorded and analyzed retrospectively. Results All procedures were finished successfully without conversion to open surgery. No severe vascular complication or other serious complications happened. The mean operative time was 146min (range, 35-240 min) ; mean blood loss was 163ml (range, 30-450 ml); mean time for postoperative drainage was 3d (range, 1-6 d) ; mean amount of postoperative drainage was 229ml (range, 45-435 ml). The postoperative hospital staying was 6-21 d, with the average of 10 days. Conclusions The LigaSure vessel sealing system produees a consistent, reliable, permanent seal of veins, arteries, and tissue bundles. It could decrease operative time and blood loss. This new energy-based vessel-ligation device appears to be effective in advanced laparoscopic procedures.

Objective To compare the image quality, radiation dose and diagnostic accuracy on film-screen, digital radiography (DR) and computed radiography (CR) mammography. Methods Three different kinds of mammography machines (film-screen, DR and CR) were tested to make sure they were qualified and comparable. Radiographies were taken on Mammo-152 phantom and ACR phantom using filmscreen, DR and CR systems with the same radiation dose. Next, radiographies were taken on two phantoms using DR and CR systems with classic mode or AEC and the radiation dose was recorded. The images were numbered and scored by eight independent experienced radiologists under the same reading condition according to ACR method. Statistics was performed with the randomized complete-block design variance analysis. The diagnostic accuracy of three kinds of mammography methods were compared with Kappa test in clinical cases who had pathologic results. Results The spacial resolution of film-screen system was the highest (7.0-8.0 Lp/mm) and that of CR was the lowest (2.5 Lp/mm). When the radiation dose was increased (27. 0%-30. 0% ), the resolution was improved with DR ( +11. 0% ) but almost no change with CR ( +1.5%). The radiation dose of DR was the lowest on ACR phantom. The delineation of mass was better on film-screen than on CR, but the delineation of fibers and speck was better on CR. When the radiation dose of CR was increased (25. 0% ), the delineation of fibers and speck on CR was similar to that on DR and the delineation of mass was similar to that on film-screen. There was a good correlation between the mammography diagnosis and pathological results (film-screen is 50/56, DR is 83/90 and CR is 61/69,P < 0. 01 and Kappa value > 0. 75) . The diagnostic accuracy of three mammography systems had no statistical difference [film-screen 89. 3% (50/56), DR 92. 2% (83/90) and CR 88. 4% (61/69),Pearson X 2=0. 722 ,P =0. 697]. Conclusion Film/screen system has the highest space resolution and DR has the lowest radiation dose. Three mammography systems have the same diagnostic accuracy for breast disease.
