OBJECTIVETo explore effects of Shenqi preparation,Traditional Chinese Medicine, on anti-fatigue and anti-oxidant functions.
METHODSOne hundred and twenty mice were randomly divided into control group and 3 experimental groups. The high, medium and low-dose of Shenqi preparation were given to the 3 experimental groups respectively, while distilled water to the control group for 15 d. The loaded swimming time, the level of lactate, serum urea nitrogen (SUN), muscle and liver glycogen, liver super-oxide dismutase (SOD), the content of malondialdehyde (MDA), glutathione peroxidase(GSH-Px) were assayed.
RESULTSThe loaded swimming test showed that the exhausted swimming time of 3 experimental groups [(296.0 +/- 25.3)s, (437.0 ĝ 38.9)s, (595.0 +/- 53.9)s respectively] was longer than that of control group [(231.0 +/- 22.5)s, P < 0.05, P < 0.01]. The liver glycogen content of the high and medium-dose experimental groups were higher than that of control group respectively (P < 0.01). The SUN content of each experimental group was less than that of the control group (P < 0.01, P < 0.05). Moreover,in the medium and high dose experimental groups, less accumulation of lactate was found (P < 0.01, P < 0.05), and the content of liver SOD and GSH-Px was higher (P < 0.01, P < 0.05). The content of liver MDA in high-dose experimental group was less than that of the control group (P < 0.05).
CONCLUSIONShenqi preparation, especially the high and medium-dose experimental groups, is able to improve exercise tolerance and has anti-fatigue and anti-oxidant effects in mice.

Objective To lessen the learning curve of percutaneous renal lithotripsy(PCNL),we introduced a novel ex-vivo learning and training model for PCNL under fluoroscopy and ultrasonography-guided access. Methods The model was set up nailing an adult porcine kidney with>3 cm ureter (freshly removed from the slaughtering factory),with a full thickness flap of the thoracic wall or abdomen wall with two ribs,to a board.The porcine kidney was placed within the flap with the catheterized ureter outside.The kidney was enclosed by the flap so as to create a roodel for percutaneous renal surgery;with the ribs overlying the upper portion of the kidney.The model was fixed to the board by two nails.Artificial stone material was implanted in the renal pelvis.Fluoroscopy guidance access:Retrograde pyelography via injection of contrast medium into the ureteral catheter images the collecting system. After the long axis of the target calyx is identified,the C-arm is rotated 30 degrees toward the surgeon,placing the C-arm axis in the same posterior plane of the kidney.The needle is advanced in the plane of the fluoroscopic beam,and the appropriate needle placement is determined by obtaining a bull's-eye sign on the fluoroscope screen. Rotating the C-arm to a vertical position monitors the depth of the needle penetration. Ultrasonography guidance access:The renal pelvis can he filled with normal saline through a catheter to simulate hydronephrosis and the target calyx is identified under ultrasonography guidance.The tract dilation and stone disintegration were followed.After training,the kidney can be opened to examine the target calyx and the complication of dilation. Results Altogether,126 urologists attended a urologic endoscopic technique training course.Of the 126 trainees,104 (82.5%) successfully performed the whole percutaneous procedure.At the end of training,114 (90.5 %) of the 126 attendees rated the porcine kidney model for simulation of percutaneous renal surgery as very helpful or helpful.Conclusions This biological training model simulates realistically the clinical procedure of PCNL with respect to trainee experience in a low stress environment that provides an opportunity for repetitive performances in order to learn basic technical skills for the clinical procedure of PCNL in the future.

Objective To assess the symptoms of patients due to indwelling double ureteral stent and their impact on quality of life. Methods Sixty patients were assessed by the specific questionnaire. Average time of indwelling stent was 21.4 d. All patients finished the special questionnaire when the stent was removed by cystoscope, including specific urinary symptoms, IPSS (international prostate symptom score), VAS (visual analogic scale) and QOL (quality of life). To assess the pain feeling, the patients were divided into 3 groups by varied methods of anesthesia, including local anesthesia, balance anesthesia and general anesthesia. Results Insertion or removal of ureteral stents with local anesthesia provoked pain in 11 of 12 (91%) patients and 8 of 10 (80%) patients in balance anesthesia group. But 38 patients of general anesthesia group did not feel any pain when inserting stents. In 54 of 60 (90%) patients, the indwelling catheter provoked one or several urinary symptoms: nocturia (70%), frequency (65%), urgency (60%), tenesmus (58%), dysuria (52%), hematuria (35 % ) and incontinence (30 %). 75 % of the patients experienced pain, in the flank and lower abdomen. 29 (48 %) patients were found to be unsatisfied with their quality of life due to the indwelling stent. Among them, 18 (62%) patients demonstrated that the provoked overactive bladder symptoms were the main influence factor of QOL, compared with 5(17 %) patients complaining pain feeling. Conclusions Urinary symptoms and pain associated with indwelling double J ureteral stents could interfere the daily activities and 50 % of patients were found reduced quality of life. Overactive bladder symptoms were the main influence of QOL during the time of indwelling stent.

The objective was to identify some biochemical and physical properties for fusion protein IL6D24-PE40KDEL. Edman degradation, SDS-PAGE, peptide mass fingerprinting, Western blot and MTT were used for identification of the protein. The results showed that the sequence of N-terminus is Met-Ile-Asp-Lys-Gln-Ile, Met was added because of prokaryotic expression system; Western blot revealed that the purified protein could react with IL6 and PEA antibody. The purified protein IL6D24-PE40KDEL could kill the multiple myeloma cell lines U266 expressing high affinity IL6R, but it could not kill the cell lines CEM which not expressed IL6R; The molecular weight was 58.7 kD measuring by SDS-PAGE; peptide mass fingerprinting (PMF) confirmed that the construction of IL6D24-PE40KDEL was correct. A novel protein by Peptident database in EXPASY web site was identified. In conclusion, IL6D24-PE40KDEL is a new targeting protein with bioactivity of specific killing effect.

Thirteen of 4-anilinoquinazoline derivatives with imine groups at position 6 of quinazoline ring were synthesized and their antitumor activities were evaluated by MTT assay and Western blotting analysis. Among these compounds, 13a-131 were reported first time. The MTT assay was carried out on three human cancer cell lines (A549, HepG2 and SMMC7721) with EGFR highly expressed. Among the tested compounds, 13i and 13j exhibited notable inhibition potency and their IC50 values on three cell lines were equivalent to or less than those of gefitinib. Compound 14, without imine group substituted, displayed excellent inhibitor potency only on A549 cell line. Compounds 14 and 13j were chosen to perform Western blotting analysis on A549. The results showed that both of the compounds could inhibit the expression level of phosphorylated EGFR remarkably. It was concluded that the inhibitor potency of compound 14 was almost equivalent to that of gefitinib and the inhibitor potency of 13j was better than that of gefitinib.
