Objective To improve the traditional percutaneous cholecystolithotripsy in order to elevate the success rate and to discuss its indications. Methods With selfmade apparatus, we modified the open procedure which is otherwise impossible in removing the stones. We have followed 120 patients for 3 to 36 months to look into the recurrence of cholelithiasis. Results We have succeeded in 287 operations in a total of 291 (98 6%) cases. Among which 99 cases (34 5%) received modified open procedures, and the postoperative course was all uneventful. 120 patients were followed up postoperatively from 3 to 36 months and the stone recurrence rate was 13 3% (16 cases). Statistical analysis showed that the stone recurrence rate in patients with 3 stones and up, or poor gallbladder function was significantly higher than those with less than 3 stones and or good gallbladder function.Conclusions The percutaneous cholecystolithotripsy with improved procedures can effectively increase the success rate of operation. According to our result the indications should be restricted to those with less than 3 stones and or with good gallbladder functions.

Objective To investigate the cardioprotective effects of 3-nitropropionic acid (3-NPA) pretreatment against ischemia-reperfusion (I/R) injury. Methods Sixteen male Wistar rats weighing 200-250 g were randomly divided into 2 groups ( n = 8 each):(1) 3-NPA group received intraperitoneal 3-NPA 4 mg?kg-1 24 h before the animals were sacrificed and (2) control group received normal saline instead of 3-NPA. The animals were sacrificed and the hearts were immediately removed and mounted on Langendorff apparatus and perfused with K-H solution saturated with 95% O2 and 5% CO2 at 37℃ . After being perfused for 30 min the hearts were subjected to 30 min global ischemia by suspension of perfusion followed by 60 min reperfusion. The HR, left ventricular developed pressure (LVDP) and ? dp/dtmaxd were recorded before ischemia and at 30 and 60 min of reperfusion. Coronary effluent was collected at 15 min of reperfusion for determination of CK and LDH activity. At the end of 60 min reperfusion the hearts were removed for determination of myocardial MDA content and SOD activity.Results LVDP and ? dp/dtmax recovered significantly better in 3-NPA group than in control group. The myocardial MDA content, CK and LDH release were significantly lower in 3-NPA group than in control group. The myocardial SOD activity was significantly higher in 3-NPA group than in control group. Conclusion Chemical preconditioning with 3-NPA protects the heart from I/R injury.

Objective To investigate the difference in complete blood count (CBC) within the defined time among 28 hospitals with different grade in Urumchi City, explore its influencing factors,offer the countermeasures, and further to provide scientific evidence for the mutual recognition among different medical institutions. Methods Totally 28 laboratories with different grade were enrolled in the investigation. Three fresh blood samples were employed to perform complete blood counting, in-cluding normal and pathological specimens. The measuring time and turn around time (TAT) were de-fined. Results According to the literature report on biological variability of testing results, the per-missible deviation of CBC was tentatively prescribed as follows: WBC 15% ;RBC 6% ;HB 7% ;HCT 6 % ;PLT 25 %. Qualification decision was based on the external quality assessment (EQA) criteria of Clinical Laboratory Centre of the Health Ministry. Qualification: the total score of five measured items is higher than or equal to 80%;disqualification: the total score of five measured items is lower than 80%. For the first and second sample, 26 laboratories (92.86%) were qualified;for the third sample (only 21 laboratories enrolled), 14 laboratories (67%) were qualified. Conclusion 28 laboratories par-ticipated in this test. The results of five items are congruent for the first and second sample (normalspecimens) in 28 laboratories, and the measured results are comparable. By contrast, the comparative result is unsatisfactory for the third sample (pathological specimen), mainly due to the narrow linear range of equipment. Meanwhile, the laboratory quality management should be strengthened.
