The Her-2 proto-oncogene encodes a 185kDa transmenbrane glycoprotein p185 which has intrinsic tyrosine kinase activity. It is overexpressed in several malignant human tumors like breast cancer. A chimeric antibody by assembling a single-chain Fv antibody and a human IgG1 Fc fragment was constructed. This chimeric antibody reacts with tumor surface antigen p185c-erbB-2 specifically. In order to put the antibody into clinical application, two steps purification method was used to attain the antibody’s purity more than 95%. Both the lyophilized pharmaceutical formulations of the antibody were found. The formulations can keep the stability and activity of the antibody for at least one year. These results were the foundation of the chimeric antibody for cancer therapy.

OBJECTIVETo evaluate the clinical effect of arthroscopic excision of the os subfibulare in anterior-lateral ankle pain.

METHODSFrom December 2005 to Augest 2014, 16 patients suffering from pain associated with an os subfibulare in the anterior-lateral side of their ankles were reviewed. Among the patients,11 patients were male and 5 were female, with a mean age of (33.5 ± 15.6) years old. The mean maximum diameter of os subfibulare was (0.70 ± 0.26) cm. All the patients underwent excision of the osseous fragments, and had anatomic reconstruction of the anterior talofibular ligament if the anterior-lateral ankle was instable. The average follow-up period was (18.0 ± 4.5) months. To analyze the surgical outcome, American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot pain and function scales,visual analogue scale (VAS) and Tegner activity scale were assessed preoperatively and postoperatively.

RESULTSAOFAS scales were preoperative 60.15 ± 14.52 and postoperative 92.35 ± 5.73. There was a significant difference between them (t = -8.251, P = 0.000). The mean VAS score were preoperative 7.35 ± 0.46 and postoperative 2.45 ± 0.98. Statistical significance was also notable (t = 18.105, P = 0.000). Tegner score was significantly increased from preoperative 2.87 ± 1.12 to postoperative 5.78 ± 1.06 (t= -7.548, P = 0.000).

CONCLUSIONIrrespective of the size of os subfibulare, in patients with pain or instability associated with the os subfibulare, arthroscopic excision combined with reconstruction of ther anterior talofibular ligament or not was effective in restoring ankle function and eliminating pain.

Multimedia computing technology teaching is a new kind teaching method. It conquers many shortcomings such as poor video, poor expression in traditional teaching of microbiology. But it can also strangle the improvising creation of different teachers in teaching and then lead it to be typical " computer teaching" . So we should obey the teaching discipline in making multimedia computing technology courseware. It can lead many sections part from the class teaching if just emphasize the full use of video and audio. We should make the purpose obviously, and make it as easy as possible in teaching, and we should also explore the fixed regularity to make the teaching and studying integrated perfectly.

BACKGROUND :Although the conventional 20 G pars plana vitrectomy can improve the prognosis of vitreous-retina diseases,but it would also cause serious operation related injury and much complications.OBJECTIVE:To evaluate the practicability and safety of 25-gauge transconjunctival sutureless vitrectomy system (TSV25G) in the macular surgery, so as to elicit the preliminary clinical experience of mimimally invasive vitrectomy system.DESIGN:Case analysisSETTING: Department of Ophthalmology, General Hospital of Chinese People's Armed Police Force; Department of Ophthalmology, Beijing Sino Japen Friendship Hospital; Department of Ophthalmology and Visual Science, Chinese University of Hong Kong; Department of Ophthalmology,Prince of Wales Hospital, Hong Kong PARTICIPANTS: From July 2003 to July 2004, 16 patients with macular diseases were admitted to the Department of Ophthalmology in the General Hospital of Chinese People's Armed Police Force and taken as subjects (n=16), they were confirmed as epiretinal membrane in 9 eyes, idiopathic macular hole in 3 eyes, traumatic macular hole in 2 eyes and vitreo-macu lar tractional syndrome in 2 eyes. The course of disease ranged from 3 to 36 months with eyesight varied between 0.06 and 0.4.METHODS: 16 eyes underwent preoperative ophthalmic evaluation in cluding visual acuity measurement, Amsler chart test, slit lamp microscopy,.indirect ophthalmoscopy tonometry and optical coherence tomography (OCT). For the macular hole patients OCT was performed. 25-gauge Transconjunctival Sutureless Vitrectomy System (TSV25G) was used to carry on minimally invasive surgery under anesthesia state, the surgical parameter was set as: high speed cutter with rate of 1500 cuts per minute,BSS bottle was hang at height of 40-50 cm, the maximum aspiration of TSV25G was 550 mm Hg with the intraocular pressure remained at around 29-35 mmHg during the operation. Three-beveled trocar were used to make three-transeonjunctival incision on sclera of about 0.5 mm long respectively in the infratemporal, superotemporal, and supraotemporal quan drants, meanwhile a transconjunctival cannula was placed. One end of the infusion tube was inserted into the infratemporal cannula to establish infusion with the other two cannulas used for the intraocular operation with 25-gauge vitreous cutter and other instruments, such as vitreoectomy and membrane dislocation. The surgery was terminated by removing the cannula except for ceaseless leak, the conjunctival and scleral incision were not sutured. Patients received follow-up examination for 1-12 months postoperatively.MAIN OUTCOME MEASURES:①The operative time and the time for the establishment of three access. ② Changes of intraocular pressure after operation. ③ The effusion from the puncture after the intraocular perfor mance. ④ The postoperative vision, operative complication and the sealing of the holes.RESULTS:All of the 16 patients completed the vitrectomy; and entered the data analysis.①16 patients complete the vitrectomy with the operative time of 28-56 minutes (the mean of 37 minutes). The average time for the establishment of three access and closing was 84 s and 32 s respectively.②The average preoperative intraocular pressure was 16.4 mm Hg,comparing with 13.5,15.5,17.9 mm Hg at postoperative 1 day, 1 w and 1 m. ③Water leakage were found in 4 wounds of three patients after operation, 3 wounds were sealed after injecting 1-2 mL disinfected air into the eyes, the other one sutured with 6-0 absorbable suture. ④The mean time of inpatients were 5 days postoperatively. The visual acuity improved in 14 patients by the average of three lines, amongst which visual acuity was found improved to above 0.8 in 5 patients and the visual distortion disappeared in 8 eyes and attenuated in 3 eyes. But still there were 2 cases without improvement.No surgical complications were noted and macular hole gained clinical sealing in totally 5 eyes.CONCLUSION: TSV25G system can simplify the surgical procedure with many other advantages such as decreasing the operation related injury and complications, as well as shortening operative time, which benefits the rapid rehabilitation.

OBJECTIVETo study the selective dilatation effects of iptakalim (Ipt) on basilar and pulmonary arterioles, and endothelial cell function of these arterioles in hypoxic rats.

METHODSSD male rats were divided into 2 groups:control and hypoxic group fed in normobaric hypoxic environment (O2 7.8%, 8 h). Arteriole rings about (204 + 5) pm were isolated and the tension of hypoxic arterioles pre-contracted by 6 nmol/L endothelin-1 (ET-1) was observed with wire myograph system model (DMT 610 m). The relaxing response of hypoxic arterioles induced by different concentration of Ipt were detected and endothelial activity was also tested by acetylcholine.

RESULTS10(5) mol/L acetylcholine (ACh)-mediated vasodilatation of basilar and pulmonary arterioles was greatly reduced in the hypoxic group than those in control group (P < 0.05). Compared with normal group, a novel ATP-sensitive potassium channel opener Ipt at the concentration ranging from 10(-11) mol/L to 10(3) mol/L, caused stronger dose dependent vasodilatation on hypoxic pulmonary arterioles, and there was no significant difference between control and hypoxic basilar arterioles.

CONCLUSIONThe endothelial function of basilar and pulmonary arterioles was damaged under hypoxic state, and Ipt selectively increased dilatation effects on hypoxic pulmonary arterioles, but not on hypoxic basilar arterioles which could improve high altitude pulmonary edema pathological state and be the novel drug in the treatment of pulmonary hypertension.

OBJECTIVETo study the clinical effect of "Jin's three-needling" in the treatment of generalized anxiety disorder.

METHODSFifty-eight patients with generalized anxiety were randomly assigned to two groups equally, the medication group treated with anti-anxiety drugs and the acupuncture group with "Jin's three-needling". The treatment course was 6 weeks. The clinical effects were evaluated with Hamilton anxiety scale (HAMA), clinical global impression (CGI), and treatment emergent symptom scale (TESS) before treatment and at the end of 2nd, 4th, 6th week of the treatment course. The concentration of 5-hydroxytryptamine (5-HT) in platelet, and plasma levels of corticosterone (CS) and adrenocorticotropic hormone (ACTH) were measured with high performance liquid chromatography-electrochemical detection (HPLC-ED) method before and after treatment.

RESULTSThe clinical effects in the two groups were equivalent, while the adverse reaction found in the acupuncture group was less than that in the medication group (P < 0.05). The platelet concentration of 5-HT and plasma ACTH level decreased significantly in both groups after treatment with insignificant difference between the group (P < 0.05). The plasma CS level had no obvious change in the two groups after treatment as compared with that before treatment respectively.

CONCLUSION"Jin's three-needling" shows similar curative effect on generalized anxiety to routine Western medicine but with less adverse reaction, which may be realized through regulating the platelet 5-HT concentration and plasma ACTH level.
