As the final step of the execution of the equipment purchase contract, acceptance check is very important for proper operation of the equipment.

0.05),but all the outcome measures at 1 month in the treatment group were significantly improved as compared with control group(P0.05).The mean light sensitivity in the treatment group was better than in control group(P

To develop the basic skills of young ophthalmic doctors,The following means can be used:the fundus examination training,doctor-patient communication ability training,teaching ward round,ward small lectures,giving patients lectures,encouraging young doctors to participate in scientific research conference and providing convenient learning places etc.for them to actively implementing knowledge and promote their ability.Ward as the earliest classroom for ophthalmic young doctor has its unique advantages,which is advantageous to the quick and good growth of young ophthalmologists.

OBJECTIVE: To explore the effects of Houttuynia Cordata on expression of human beta-defensin-2 (HBD-2) in pulmonary epithelial cells (SPC-A-1) in vitro; and to observe the correlationship between the level of HBD-2 mRNA and the concentrations or treatment times of Houttuynia Cordata. METHODS: The SPC-A-1 cells were cultured with different concentrations of Houttuynia Cordata in vitro, including 0, 12.5, 25, 50, 100 and 200 microg/ml. And then, the SPC-A-1 cells were cultured with the optimal concentration of Houttuynia Cordata in different lengths of time, including 1, 2, 4, 8, 16 and 24 hours. After the treatment, the mRNA level of HBD-2 in pulmonary epithelial cells was detected by means of semi-quantitative reverse transcription polymerase chain reaction (RT-PCR). RESULTS: After being cultured with Houttuynia Cordata, the expression of HBD-2 mRNA had positive correlation with the stimulus concentrations (rs=0.829, P=0.042) and stimulus time (rs=0.914, P=0.003). The highest expression of HBD-2 mRNA was induced by 100 microg/ml Houttuynia Cordata after 8-hour treatment. In comparison with the normal control group and the interleukin-1beta group, 100 microg/ml Houttuynia Cordata could significantly up-regulate the expression of HBD-2 mRNA in SPC-A-1 cells after 8-hour treatment (P<0.01). CONCLUSION: Houttuynia Cordata can up-regulate expression of HBD-2 mRNA in SPC-A-1 cells, and the highest expression level of HBD-2 mRNA can be obtained by culture with 100 microg/ml Houttuynia Cordata for 8 hours.

Objective:To study the bactericidal effect of ultrasonic technique combined with saline(SL),sodium hypochlorite(SH) or Koutai(KT) irrigation in root canal preparation. Methods:120 single-rooted teeth in 120 patients with chronic periapical periodontitis were divided into six groups randomly with 20 in each group.The tooth canal in group A, B and C were prepared with ultrasonic technique. SL, SH and KT were used to irrigate in the root canals group A,B and C respectively.Routine hand instruments were used in group A1, B1 and C1.SL, SH and KT were used as irrigations in group A1, B1 and C1 respectively.30 ?l of liquid sample was obtained from each root canal and examined for anaerobic bacteria colony counting before and after root canal preparation. Result:After root canal preparation the number of anaerobic bacteria colony was significantly reduced in all the 6 groups(P

Objective: To study the optimum process of Shanxiangyuan (Turnipia argute) Baccal Tablet. Methods: Inhibition effect on bacteria is observed and concentration of ursolic acid is determined for choosing the optimum process of Shangxiangyuan Baccal Tablet. Results: The optimum process is that the crude powder of the leaves of Turnipia arguta is soaked by 70% alchol for 72 hours and percolated. The liquid is concentrated to the density of 1.20. Sugar powder and dextin are as excipients. The granules are made by the way of spray drying. Conclusion: The process is reasonable and favorable for industrial production.

Objective To evaluate the utility of clinical characters and variant examinations in discriminating benign from malignant thyroid lesions before operation.Methods We had retrospectively analyzed 1367 cases of thyroid nodule that were operated in Ruijin Hospital from 1999 to 2004.Results Clinical symptoms and signs,ultrasonography and fine needle aspiration(FNA)were all useful in indicating malignant thyroid lesions,especially FNA,whose sensitivity,specificity and diagnostic accuracy were 65.12%,95.08% and 82.69%,respectively.By logistic regression analysis,the thyroid nodule of young patients or solid or hard nodules,or nodules hard,or accompanied with calcification or nonached lymphadenectasis might be maligment nodules.At this time,FNA shoud be performed.Conclusion The above findings emphasize the importance of reviewing carefully and utilizing effectively the clinical information of each patient.

Objective:To establish a method for the determination of total chloride in oral rehydration salts powder (Ⅲ) by ion chromatography (IC). Methods:The analysis was performed on an IonPac AS 14A (250 mm × 4 mm) column with an IonPac AG 14A (50 mm × 4 mm) guard column and 9mmol·L-1 Na2 CO3 solution as the mobile phase. The flow rate was 1. 0 ml·min-1 with isocratic elution and the sample size was 25 μl. The suppressor was AERS 500(4mm) with 45mA suppression current, and an ECD was used for the detection. The quantity of chloride ion ( Cl-1 ) was calculated by the peak area with an external standard method. Re-sults:The linear range of Cl-1 was 0. 05-20. 00 mg·L-1(r=0. 9999);the recovery was 98. 89％(RSD=0. 56％, n=6). Conclu-sion:The results demonstrated that the method has the advantages of high sensitivity, simple sample pretreatment, promising accuracy and good reliability, which is suitable for the determination of total chloride in oral rehydration salt powder (Ⅲ) .

This thesis introduced the situation of the pharmacy administration undergraduate course construction of Shenyang Pharmaceutical University. From the background of setting up of the pharmacy administration program,and in combination with the characteristics of the program,this thesis suggested that five principles should be followed to the course system construction,and expounded the concrete conditions of the curriculum setup and the next step assumption.

Ideal blood glucose control requires accurate insulin injections under the guidance of frequent glucose monitoring.Artificial pancreas (AP),the closed-loop control system can adjust the input amount of insulin automatically with the body's blood glucose levels.The AP allows diabetics to control blood glucose ideal,then get the benefit of prevention of complications and bring convenience and safety in clinical application.Accuracy is the key issue of the AP.To improve the accuracy of such a system need to improve the detection accuracy and reliability,increase speed and accuracy of the output control,and improve the accuracy of the system regulation model.
