When the patients with senile or secondary osteoporosis are treated with screw fixation, the screws are likely to get loose or pulled out. Polymethylmethacrylate (PMMA) can enhance screw fixation strength to some extent in clinic, but PMMA has such disadvantages as irresorbability, polymeric heating effect and toxic reaction so that its clinical application is limited. Calcium phosphate cement, however, has drawn much attention because it gets rid of the shortcomings of PMMA. This article introduces recent progress made in research on fixation with calcium phosphate cement enhancing screw.

Objective:To study the fear extent toward root canal therapy (RCT).Methods: A survey with questionnaires was conducted in 103 adult patients who had received RCT.Results:44.7% of the subjects reported a decrease in fearfulness to endodontic procedures as the result of having experienced RCT.Local anesthetic injection,file introducing into or working in root canals and tapping on a sore tooth were ranked as 6th,5th,7th for the fear.Only 50.4% of the patients would choose RCT again for teeth preserving treatment.Conclusion:The fear extent toward RCT depends on the steps of the procedure.Local anesthetic injection,file introducing into or working in root canals and tapping on a sore tooth may be the most factors for anxiety in patients.

The bacterial strain CSS-4-2 isolated from the spleen of Carassius auratus of penze(♀) ? Cyprinus acutidorsalis (♂) with septicemia was proved to b e a pathogen by artificial infection. This bacteria has short rod-shaped cells , Gram negative and motile, with single polar flagellum, and with not capsule. No spore was formed , and it was resistant to 0/129. It could utilize glucose, mal t ose ,mannite, sucrose and inositol, but could not utilize malonate, lactose, xyl ose, raffinose, sorbin and adonitol. Oxidase and arginine dihydrolase was posit ive.While urease, lysine decarboxylase and ornthine decarboxylase was negative .Bacteriological identification by VITEK-AMS-60 showed the strain CSS-4-2 w as Aeromonas caviae. Drug sensitivity assay showed that this strain was sen sitive to s treptomycin, tobramycin, chloromycetin, rifampicin, norfloxacin and nitrofuranto in, but resistant to penicillin G.

The growth property of pathogenic bacterium Aeromonas caviae strain CSS-4-2 which was isolated from the spleen of Carassius auratus of penze(♀) ? Cyprinus acutidorsalis (♂) that diseased septicemia was studied.The growth curve of CSS-4-2:lag phase was in 0～3h,log phase was in 3～30h, stationary phase was in 33～36h,decline phase was after 36h when CSS-4-2 was cultured shaking in tryptone liquid medium. It's optimum growth temperature ranges from 25℃ to 30℃, optimum growth pH ranges from 5 to 10, and optimum salinity ranges from 0% to 1% Nacl concentration .

Objective To assess the left ventricular contraction asynchrony in patients with acute myocardial infarction(AMI) by velocity vector imaging(VVI).Methods Sixty AMI patients and 40 healthy volunteers were included.Using VVI,the time to peak longitudinal systolic velocity (TL-V) was measured in the left ventricular long axis views,the time to peak radial systolic velocity (TR-V) was measured in parasternal short axis views.The deviation of the earliest and the latest TL-V and TR-V (Ts max-min) was measured,and the standard deviation of TL-V and TR-V (TS-SD) was also measured.Results ①TL-V ,TR-V of the infarcted and non-infarcted segments in patients with acute myocardial infarction were longer than those of the normal segments (P ＜0.05).②The longitudinal Tsmax-min,Ts-SD and the radial Tsmax-min,Ts-SD in infarcted patients were increased compared with the healthy volunteers (P ＜0.001).③Ts of the infarcted segments was increased in turn from the class Ⅰ to class Ⅳ of the cardiac function (P ＜0.001).Conclusions VVI could be used to assess the left ventricular contraction asynchrony in patients with AMI.VVI is a new useful method to determine the infarcted segments.

After summing up the experience of recent years' clinic teaching, ICU department in Fangcun Branch of Second Clinical Medical College of Guangzhou University of TCM comes to a conclusion that, the clinical teaching of ICU should pay attention to and ensure effective implementation of beginning educationg. And following the PDCA method (Plan, Do, Check & Act) will make the work orderly, normative and controllable and meanwhile raise the students' observing and analysis ability as well as their operation and doctor-patient communication ability. In this way we can mostly enhance the effect of teaching.

With the development of radiotherapy techniques,the efficacy of radiotherapy for liver tumors has been improved,and radiothera-py can be considered as an alternative treatment for patients who are not suitable for surgery.The progress in liver tumor radiotherapy repor-ted in the 55th annual meeting of the American Society for Therapeutic Radiology and Oncology (ASTRO)in 2013,particularly the efficacy and safety of stereotactic body radiation therapy for liver tumors,is reviewed.In the future,radiotherapy may be increasingly used as an ef-fective method in the treatment of liver tumors.The main studies reported at the meeting are sorted as follows in this article.

Objective: To develop a GC-MS method for the simultaneous determination of six active constituents ( borneol, isoborneol, cinnamaldehyde, cinnamic acid, muscone and benzyl benzoate) in Shexiang Baoxin pills. Methods: A gas chromatogra-phy-mass spectrography (GC-MS) method was adopted using a DB-5 capillary column (30 m × 0. 25 mm,0. 1 μm). The column tem-perature was raised as the following program:the initial temperature was 70℃, maintained for 2 min, raised the temperature (5℃· min-1) to 150℃, maintained for 4 min and then raised the temperature (20℃·min-1) to 260℃, and maintained for 3 min. The range of mass-to-electric charge ratio was 10 to 425. Results:The calibration curves of borneol, isoborneol, cinnamaldehyde, cinnam-ic acid, muscone and benzyl benzoate were linear within the range of 0.022-22.000 μg·ml-1(r=0.999 6),0.024-24.000 μg· ml-1(r=0.999 6),0.028-28.000μg·ml-1(r=0.999 8),0.034-34.000μg·ml-1(r=0.999 6),0.040-40.000μg·ml-1(r=0.999 7) and 0.050-50. 000 μg·ml-1 (r =0.999 9), respectively. The average recovery was 97.20%, 97.40%, 97.53%, 99. 60%, 98. 78% and 98. 27% and RSD was 0. 89%, 1. 18%, 1. 52%, 1. 49%, 0. 79% and 1. 74%(n=6), respectively. Con-clusion:The method is accurate, suitable, convenient and reproducible, which can be used for the quality control of multi components in Shexiang Baoxin pills.

Objective To study the application of doses of remifentail intravenous anesthesia in vocal nodule extirpation.Methods Sixty ASAⅠ～Ⅱpatients with vocal nodule were selected and randomly divided into three groups. Group F were given anesthetic induction with fentanil and maintenance with isoflurane; Group L were given anesthetic induction and maintenance with remifentail at the dose of 0.5?g/(kg?min); Group H were given anesthetic induction and maintenance with remifentail at the dose of 1?g/(kg?min).The anesthetic induction time,blood flow dynamics during maintenance phase,recovery time and quality were recorded. Results (1)Anesthesia produce less circulatory fluctuation in group H than in group F and L.(2) Group L and H were faster than group F on recovery profile including the time of response to verbal commands,autonomous breathing,tracheal extubation and discharging from operating room. The OAA/S score was higher in group L and H than in group F 5 min after intubation. There were no significant differences between group L and H. Conclusions Remifentanil intravenous anesthesia can achieve better recovery profile from anesthesia than fentanyl in vocal nodule extirpation. 1?g/(kg?min) remifentanil can inhibit the stress responses to tracheal intubation and laryngoscope inserted effectively with a stable circulatory function.
