Objective To observe the effect applicated of endoscopic sinus joint laryngoscope in laryngeal microsurgery.Methods 68 patients with laryngeal lesions were randomly divided into the multi-mirror combination group (34 cases) and the single laryngoscope group (34 cases).The multi-mirror combination group was taken with laryngeal microsurgery under endoscopic Joint laryngoscope.The single laryngoscope group was only taken with laryngeal microsurgery under laryngoscope.The efficacy and surgical situation of the two groups were compared.Results The total effective rate of the multi-mirror combination group was 97.06％,which was significantly higher than that of the single-laryngoscope group (85.30％) (x2 =4.031,P ＜ 0.05).Compared with the case of surgery and complications and recurrence rate,the multi-mirror combination group was superior to the single laryngoscope group (all P ＜ 0.05).Conclusion The endoscopic joint laryngoscope has the function of expanding the scope of the operative field and increasing the focus and clarity,and also has the advantages of small traumatic for patients,fewer complications,low recurrence rate,easy operation and high accuracy.

Objective This pre-DIC rat models were constructed by injecting LPS in order to reveal the relationship and significance among tissue factor pathway inhibitor (TFPI),platelet, fibrinogen, prothrombin time and activated partial thromboplastin time. Methods Enzyme-labeled immunosorbent assay was used to detect blood plasma TFPI in pre-DIC state rats(n=16),DIC state rats(n=8)and health rats(n=8).Platelet, fibrinogen, prothrombin time and activated partial thromboplastin time in the same rat were detected. Results TFPI increased first(pre-DIC state)and then decreased(DIC state)in the blood plasma of rata, but the levels of TFPI were always higher than that in the normal state. Conclusions TFPI is more sensitive and accurate to monitor the pro-DIC state than routine examination, which is very useful in the early diagnosis of pre-DIC state.

AIM: To establish a standard for quality control of Xinfang Biyan Capsule(Radix Saponikovae, Radix Angelicae Dahuricae, Radix Scutellariae, etc.). METHODS: TLC and HPLC were used. RESULTS: Flos Magnoliae, Radix Saponikovae, Flos Chrysanthemi, Radix Bupleuri in the capsule could be identified by TLC, and baicalin content in the capsule could be measured by RP-HPLC with a linear relatioship at a range of 0.243 ?g- 2.43 ?g(r= 0.999 8 ). The average recovery was 98.15% and RSD was 0.15% . CONCLUSION: The methods are accurate and can be used for the quality control of Xinfang Biyan Capsules.

In this article, HPLC fingerprint analysis method for total flavonoids from pollen of Brassica campestris L.was established., The HPLC fingerprint was performed on Waters C18 column (250 mm × 4.6 mm, 5 μm), eluted gradiently with the mixture of acetonitrile and 0.4% phosphoric acid aqueous solution at a flow rate of 0.8 mL·min-1. The column temperature was 40℃. The detection wavelength was 320 nm. The HPLC standard fingerprint of total flavonoids from pollen of Brassica campestrisL. was established, and 16 common peaks were calibrated. The method was simple, stable, and reproducible. It could be applied for quality control of total flavonoids from pollen of Brassica campestris L.

Objective To explore the behavior characteristics in children with benign epilepsy combined with centro-temporal spikes(BECTS).Methods Eighty-two children with BECTS aged 2.5-3.0(2.65?2.31)years old,51 male,31 female,who were free of mental retardation assessed with Gesell developmental schedules,untreated with antiepileptic drugs,and were investigated 15 days after the latest seizure.Eighty-two healthy children with sex and age matched to the cases,53 male,29 female,aged 2.5-3.0(2.6?0.4)years old.The behavior characteristics of infants in BECTS group and control group were assessed with CBCL,including 6 behavior factors which were sleep problem,social flinches,depression,physical aspect,attacking,act of sabotage and the infants-middle school student social ability scale.Results The total scores of behavior characteristics and the scores of depression,sleep problem,attacking and act of sabotage in BECTS group were all higher than those in control group,the differences were statistically significant.However,scores of social flinches,and physical aspect in BECTS group had no significant differences compared with those of control group.There were no significant difference of social adaptive component between the BECTS and control group.Conclusions Children with BECTS have behavior disorders to some extent,but their social adaptive capacity are the same as normal children.

OBJECTIVETo assess the feasibility and safety of robot-assisted laparoscopic radical prostatectomy (RLRP) in the treatment of prostate cancer.

METHODSUsing the da Vinci robot surgical system, we performed RLRP for 34 patients with localized prostate cancer and analyzed the intraoperative and follow-up data.

RESULTSThe procedures were performed successfully in all the patients, with the mean operation time of 198 min (range 135-340 min), average blood loss of 257 ml (range 50-700 ml), and 1 case of blood transfusion, but no postoperative complications. Three cases had positive surgical margins. Postoperative examination at 4 weeks showed PSA > 0.2 microg/L in 2 cases, suggestive of residual tumor, for which maximal androgen block therapy was administered. The other 32 patients were followed up for 3-10 (mean 7.5) months, during which the average level of serum tPSA remained < 0.2 microg/L. Urinary continence was found in 94% (32/34) and 97% (33/34) of the patients at 3 and 6 months, respectively, of whom 77% (26/34) and 88% (30/34) had no urinary leakage (0 pad per day).

CONCLUSIONRLRP, with its advantages of less perioperative blood loss, low rate of positive margin, and good urinary continence, is a safe and effective surgical option for the treatment of prostate cancer.

Heavy-ions have the similar characteristic of depth-dose distribution with protons, but exhibit enhanced physical and radiobiological benefits. With increasing development in technical and clinical research, more facilities are being installed in the world. At the same time, many critical techniques of heavy-ion therapy facility were optimized and completed. This paper classified and reviewed the basic structure of heavy-ion system equipments, especially the accelerator, gantry, nozzle , TPS.
