Objective To evaluate the efficacy and safety of percutaneous nephroscopic lithotripsy for the treatment of bilateral upper urinary calculi. Methods From July 2004 to December 2008,we performed percutaneous nephroscopic lithotripsy under X-ray or ultrasonic guidance for 35 patients with bilateral upper urinary calculi. Of the 35 patients,bilateral renal calculi were found in 18 patients,unilateral renal and unilateral ureteral calculus in 10,bilateral ureteral calculi in 7. Results In 35 patients (70 sides),the calculi was removed through a single tract in 49 sides,through double tracts in 18 sides,and through triple tracts in 3 sides. The mean operation time for unilateral PCNL was 66 min (ranged from 20 to 185 min). The stone-free rate was 80% (56/70) on one session. A second-look stone removal was needed in 8 laterals,and 3 laterals underwent three times of lithotomy. In three sides,a few residual renal stones were found after the first operation,but no second operation was performed. The final stone-free rate was 91.4% (64/70) in all of the cases,among which the stone-free rate was 100% (24/24) for ureteral stones and was 87% (40/46) for renal stones. In this series,no chest or abdominal injuries,intestinal perforation,or injuries to surrounding organs were detected. The patients were discharged from hospital in 5 to 30 days,and then were followed up for 3 to 6 months. During the follow-up,B-ultrasonography and KUB+IVP found no recurrence of calculi. Conclusions Percutaneous nephrolithotomy is effective and safe for bilateral upper urinary calculi. By skilled urologists in conditioned hospital,simultaneous bilateral percutaneous nephrolithotomy performed on bilateral upper urinary calculi can shorten the cycle time of treatment and hospitalization.

Objective To evaluate the efficacy and safety of percutaneous nephrolithotomy under ultrasonic guidance for the treatment of renal calculi. Methods Percutaneous nephrolithotomy using pneumatic or holmium laser lithotripsy under ultrasonic guidance was performed in 26 patients from January 2005 to November 2006.Among them,46 patients had single stones and 27 had multiple renal calculi.Unilateral renal calculi were found in 67 patients and bilateral calculi in 6.Staghorn calculi were identified in 11 patients.Results Of the 73 patients,a successful stone removal on one session was achieved in 57 patients,a second-look stone removal was needed in 13 patients,and 3 patients underwent three times of operation.During the operation,a single tract was used in 53 patients,double tracts in 18 patients,and three tracts in 2.A mini-invasive tract(F14～F18) was used in 47 patients,and a standard tract(F24) was established in the remaining 26 patients.The operation time was 50～160 min(mean,86 min).The stone-free rate was 96.2%(68/73),and the residual stones in other 5 patients were all

Objective To investigate a new method of pneumatic ballistic lithotripsy for the treatment of bladder calculi. Methods A ureteroscope or nephroscope was inserted into the bladder via outer sheath of resectoscope. Then pneumatic ballistic lithotripsy was performed under endoscope to fragment and remove bladder stones. Results Stones were thoroughly removed from the bladder on one session in all 20 patients. No major haemorrhage, perforation of the bladder, or water intoxication happened intraoperatively or postoperatively. Follow-up for 2~18 months (mean, 4 6 months) in the 20 patients showed no recurrence of calculi under B-ultrasonography or symptoms of urethral stricture like dribble urination. Conclusions Pneumatic ballistic lithotripsy via outer sheath of resectoscope is effective in the treatment of bladder calculi.

Tanshinones, the main bioactive compounds of Salvia miltiorrhiza, are the diterpenoid pigments, multiple genes were proved to be involved in their biosynthesis in plants. CYP76AH1 is the initial P450 gene in the tanshinones biosynthetic pathway, its function has been validated by yeast expression and in vitroenzymatic reaction. In order to clarify the function of CYP76AH1 in vivo, in this study, we constructedthe RNA interference of CYP7AH1 in S. miltiorrhiza hairy root. The RNA interference vector with a hairpin structure was constructed using the Gateway technology, and then the interference fragment was integrated into the genome of S. miltiorrhiza mediated by Agrobacterium rhizogenes. Several highly CYP76AH1 interference S. miltiorrhiza hairy roots were obtained for further analysis.

As an indispensable part of minority traditional medicine, mineral medicine has used with less dosage and reliable efficacy for the last thousand years. Based on the unearthed relics and medical literatures of past dynasties, the history of Han nationality ap- years, which had been recorded in main literature. But there is less comprehensive report of its usage in the other 55-minority nationality. This article was based on the analysis of ethnic minority literature of thousands of years, and conducted a comprehensive collation and analysis of mineral medicine. It was mostly determined that there was 20 minority groups using mineral medicine, with a total of 163 species (limited our references), and the most used is the Tibetan, accounting for 141. The most serious problems of mineral medicine are that species should be further investigated and researched, and then become the legal commercial medicine, and the classification principles of mineral medicine should be established. Through the traditional processing and experimental studies, the problems of attenuation and detoxification should be solved.

The biotechnology of glycolipid fermented b y a bacillus coagulans was studied and the fermentation pro cess in 10L bioreactor was conducted.Suitable medium contained 6% bean oil as ca rbon source,3 5g/L NaNO 3 as nitrogen source,0 75g/L yeast extract and some i no rganic salts.The fermentation temperature of 30℃,initial pH of 8 5,strring rev olution of 150～240r/min and fermentation period of 96h proved to be optimal.The yield of glycolipid in 10L bioreactor was 7 073g/L.

Objective To determine the dietary nutritional status of rural residents in Midwestern Shandong Province,in order to improve the dietary pattern and health status of them.Method 11 987 residents,from 10 273 households,were included in this study by multi-stage randomized cluster sampling in 8 counties located in Midwestern Shandong Province.Questionnaire of Food Frequency (QFF) was applied to collect the information about the amount and frequency of food consumed by the subjects in the past year.Results The average intake of cereal,vegetable,fruit,meat,egg,milk,bean,oil and salt per reference man per day was 553.9 g,310.6 g,58.2 g, 36.3 g,50.1 g,16.7 g,34.4 g,44.8 g and 12.3 g,respectively.The average intake of energy,carbohydrate,protein,fat and dietary fiber per reference man per day was 12 095.6 kJ,451.8 g,85.6 g,78.8 g and 18.7 g as well Cereal food provides 66.1% of total energy; however,the meat provides only 6.6% of that.Carbohydrate,protein and fat amount to around 63.2%,12.0% and 24.8% of total energy, respectively.24.0% of fat intake was from animal food,while 76% of that was from vegetable food.Conclusions The intake of energy, protein,fat was sufficient for these subjects;however,the intake of vegetable,fruit,bean and meat was lower than the dietary reference intake.Moreover,oil and salt intake in these subjects was much higher than Chinese Recommended Nutrient Intakes.Thus,the amelioration of dietary pattern in rural residents will be an important task for nutrition workers in rural area of Midwestern part of Shandong Province in the future.
