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.

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 clone and express the extracellular portion of mouse Fcγreceptor Ⅱ-b ( FcγRⅡb) and to analyze the functions of the expressed proteins in a mouse model of systemic lupus ery-thematosus ( SLE) .Methods The gene fragment encoding FcγRⅡb was amplified by PCR, and then in-serted into the prokaryotic expression vector pET-32a(+) to construct the recombinant expression plasmid pET-FcγRⅡb.The expression plasmid was identified with restriction enzymes and then sent to the Shanghai Bio-Engineering Co.LTD for further sequencing analysis.The transformed Escherichia coli ( E.coli) BL21 ( DE3) strains carrying the recombinant expression plasmid pET-FcγRⅡb were induced by isopropylβ-D-1-thiogalactoside ( IPTG) .The expressed fusion proteins were analyzed by Western blot assay and purified with purification kits.The immune complex ( IC)-binding ability of FcγRⅡb was measured by ELISA.MRL/lpr mice with SLE in both the prevention (12 weeks old, n=40) and the treatment groups (19 weeks old, n=40) were randomly divided into four groups including 60 μl (4.8 μg) treatment group, 120 μl (9.6 μg) treatment group, 180μl (14.4μg) treatment group and PBS treatment group with 10 mouse in each group. The MRL/lpr mice with SLE were injected with the fusion protein through tail vein once a week for four con-secutive weeks.Serum samples were collected from each mouse after one week of observation.The levels of FcγRⅡb in soluble form in mice form both the prevention and treatment groups as well as the levels of anti-double stranded DNA antibodies were detected by ELISA.Results The gene encoding FcγRⅡb was ampli-fied and the recombinant expression plasmid pET-FcγRⅡb was successfully constructed.The recombinant proteins were expressed in the prokaryotic expression system, and then successfully purified.The recombi-nant proteins could bind to IC.Compared with the corresponding PBS control group, the levels of FcγRⅡb in soluble form were increased in mice from both prevention and treatment groups after treating with various concentrations of the recombinant protein (P<0.05).Significant differences in the levels of FcγRⅡb were found among mice of the same age after treating with different concentrations of the recombinant protein ( P<0.05).Compared with the corresponding PBS control group, the levels of anti-double stranded DNA anti-bodies were decreased in mice from both prevention and treatment groups after treating with various concen-trations of the recombinant protein (P<0.05).The levels of anti-double stranded DNA antibodies were grad-ually decreased along with the increasing dosage of protein (P<0.05).Conclusion The extracellular por-tion of murine FcγRⅡb in soluble form was successfully expressed.The recombinant proteins played a cer-tain role in the prevention and treatment of SLE in a mouse model.

Objective To investigate effect of double end-to-side neuroanastomosis for bilateral obsolete proper digital nerve injuries.Methods From November 2000 to October 2009,40 patients with bilateral obsolete proper digital nerve injuries were admitted to our center.Fifteen patients underwent double end-to-side neuroanastomosis.During operation,the injured digital nerve was excised,then bilateral distal ends and proximal ends were sutured,respectively; consequently,the distal and proximal nerve bows were formed.A cutaneous antebrachii lateralis nerve was freed and obtained from the homolateral forearm,then divided equally to 2 parts which were used to bridge the 2 nerve bows.Thirteen patients underwent single end-to-side neuroanastomosis,while other 12 patients underwent end-to-end neuroanastomosis.Results Thirty one patients were successfully followed up for 6 to 8 months.In double end-to-side neuroanastomosis group,12 patients were successfully followed up; anaesthesia and pain of the injured fingers disappeared completely; finger pulp was plump with good flexibility; the average result of sensation measurement was S(4.21 ±1.97),which was significantly higher than those of the other 2 groups; the average result of two point discrimination was 5.4±0.9 mm which was significantly lower than those of the other 2 groups.In single end-to-side neuroanastomosis group,10 patients were successfully followed up; anaesthesia relieved and spontaneous pain disappeared completely,but there was still tenderness; the average result of sensation measurement was S(1.57±0.72); the average result of two point discrimination was 7.2±1.2 mm.In end-to-end neuroanastomosis group,9 patients were successfully followed up; anaesthesia and pain relieved; the average result of sensation measurement was S(3.19± 1.04); the average result of two point discrimination was 7.68±0.8 mm; there were significant differences in results of sensation measurement and two point discrimination between the latter two groups.Conclusion The double end-to-side neuroanastomosis is a valuable method for repairing bilateral obsolete proper digital nerve injuries.
