Objective To investigate the causes and preventive measures for failure and complications of minimally invasive percutaneous nephrolithotomy (mPCNL). Methods From January 2005 to October 2008,totally 353 cases of mPNCL were performed in our hospital. Among the cases,30 patients experienced failure of the surgery or postoperative complications. The data of the 30 patients were analyzed retrospectively in this study. Results Of the 30 cases,puncture failure occurred in 5 patients,while 2 of them were converted to open surgery,and the other 3 were treated by a second puncture successfully; Zebra wire extrusion was found in 5 cases,who were then cured by re-puncture or a second operation; in 3 patients,the wire or PCN tube was moved into the renal vein (2 cases) or the colon (1 case) without causing bleeding or intestinal fistula,the cases were cured afterwards by a second operation; 3 patients developed hydrothorax and then was cured by chest drainage; postoperative arteriovenous fistula was detected in 2 patients,who were cured by interventional therapy; in 5 days after the operation,one patient developed massive hemorrhage from the PCN tube when driving cars,and then recovered by clipping the PCN tube and hemostasis; another patient showed hemorrhage and infection due to extraction of the PCN tube,and open surgery was carried out to cure this patient. Conclusions Failure of puncture and Zebra wire extrusion are most common causes of failure of mPCNL. Whereas,post-mPCNL complications is often caused by unskillful surgeons or noncompliant patients.

Objective To discuss the value of Fisher discriminant analysis of serum progesterone and the growing rate of β-human chorionic gonadotropin in the prediction of early ectopic pregnancy. Methods 66 patients with ectopic pregnancy (11 cases were successfully treated expectantly and 55 cases were treated surgically including 40 cases of rupture of fallopian tube and 15 cases of tubal abortion) and 55 patients with intrauterine pregnancy and 50 patients with threatened abortion were chosen. Serum progesterone,β-HCG,48 hβ-HCG and the 48 h growing rate of β-HCG in each group were measured and a Fisher discriminant analysis was used. Results The serum progester-one was (30.27± 18.20) nmol/L in ectopic pregnancy group,( 108.44±23.27 ) nmol/L in intrauterine pregnancy group and (91.68±34.90) nmol/L in threatened abortion group. The first β-HCG was ( 3767.63 ± 3530.38 ) U/L in ectopie pregnancy group,(29 028.65 ± 10 874.01 )U/L in intrauterine pregnancy group and (13 457.47±16 367.65)U/L in threatened abortion group. The second β-HCG was (4349.24±3536.22)U/L in ectopic pregnancygroup,(56 139.46 ± 23 296.87 ) U/L in intrauterine pregnancy group and (23 270.63 ± 23 811.68 ) U/L in threat-ened abortion group. The growing rate of β-HCG ( β-HCG/the first serum β-HCG) was 1.29 ± 0.28 in ectopic preg-nancy group,1.93 ± 0.36 in intrauterine pregnancy group and 1.97±0.28 in threatened abortion group. There was significant difference in serum progesterone,the first β-HCG and the second β-HCG as well as the growing rate of β-HCG among the groups(P<0.05 or <0.01). Fisher discriminant analysis of combing progesterone and the growing rate of β-HCG were connected with diagnosis of ectopic pregnancy,however,the only one serum β-HCG was not con-nected with diagnosis of ectopic pregnancy. 98.5% of ectopic pregnancy,65.6% of intrauterine pregnancy and 64.0% of threatened abortion were correctly classified in the Fisher discfiminant analysis,with overall correct rate of 77.8%. Conclusion Fisher discriminant analysis of combing progesterone and the growing rate of β-HCG can bet-ter predict the early ectopic pregnancy.

The Ebola virus is highly infectious and can result in death in ≤ 90% of infected subjects. Detection of the Ebola virus and diagnosis of infection are extremely important for epidemic control. Presently, Chinese laboratories detect the nucleic acids of the Ebola virus by real-time reverse transcription-polymerase chain reaction (RT-PCR). However, such detection takes a relatively long time and necessitates skilled personnel and expensive equipment. Enzyme-linked immunosorbent assay (ELISA) of serum is simple, easy to operate, and can be used to ascertain if a patient is infected with the Ebola virus as well as the degree of infection. Hence, ELISA can be used in epidemiological investigations and is a strong complement to detection of nucleic acids. Cases of Ebola hemorrhagic fever have not been documented in China, so quality-control material for positive serology is needed. Construction and expression of human-mouse chimeric antibodies against the nucleoprotein of the Ebola virus was carried out. Genes encoding variable heavy (VH) and variable light (VL) chains were extracted and amplified from murine hybridoma cells. Genes encoding the VH and VL chains of monoclonal antibodies were amplified by RT-PCR. According to sequence analyses, a primer was designed to amplify functional sequences relative to VH and VL chain. The eukaryotic expression vector HL51-14 carrying some human antibody heavy chain- and light chain-constant regions was used. IgG antibodies were obtained by transient transfection of 293T cells. Subsequently, immunological detection and immunological identification were identified by ELISA, immunofluorescence assay, and western blotting. These results showed that we constructed and purified two human- mouse chimeric antibodies.

Objective To evaluate the plasma levels of adrenomedullin (ADM) and urotensin Ⅱ ( U-Ⅱ ) in children with capillary bronchiolitis, and their clinical significance. Methods One hundred and fifty three children with capillary bronchiolitis and 36 healthy children were recruited. Plasma levels of ADM and U- Ⅱ were measured at acute stage ( <7days) and convalescent stage (>14days) of airway inflammation. The relationship of plasma ADM and U-Ⅱ levels with symptom scores was evaluated. Results Plasma levels of ADM and U-Ⅱ in acute stage of capillary bronchiolitis were significantly higher than those in convalescent stage and healthy controls ( ADM: t = 20. 57 and 26. 26, P < 0. 01; U-Ⅱ: t = 14. 27 and 7. 61, P < 0. 01 ) , and there were significant differences among mild, moderate and severe capillary bronohiolitis (F = 245. 94 and 304. 79, P <0. 01). Plasma level of U-Ⅱ in convalescent stage of capillary bronchiolitis was lower than that of healthy controls (t = 6. 99, P <0. 01 ) , but ADM was still in a higher level ( t = 8. 98, P < 0. 01 ). In the convalescent stage, there was significant difference on U-Ⅱ levels among mild, moderate and severe capillary bronchiolitis ( F = 25.69, P < 0. 01 ) , but no significant difference was observed for ADM levels (F = 2. 25 , P > 0. 05 ) . Plasma levels of ADM and U- Ⅱ in acute stage showed positive correlation with symptom scores, and the regression coefficients were 0.884 (P =0. 000) for ADM and 0. 943 (P = 0. 000) for U-Ⅱ . Conclusion Plasma ADM and U-Ⅱ levels in children with capillary bronchiolitis are increased in acute stage and correlated with the symptom scores, which may serve as laboratory indicators for assessing the severity of the disease.

OBJECTIVETo compare the clinical efficacy of the lymph node dissection patterns of the reverse and the traditional cabbage in hand-assisted laparoscopic D2 radical gastrectomy (HALG).

METHODSFrom December 2010 to October 2013, 194 patients with HALG in Chengdu Military General Hospital were enrolled in this study. According to the pattern of lymph node dissection, 108 patients were performed with the reverse procedure which took spleen as starting point, from left to right, and 86 patients were performed with the traditional cabbage procedure which took the abdominal cavity as the center, from both sides to middle. A retrospective comparative analysis was made on the intra- and post-operative data between the two groups.

RESULTSAll the patients were successfully performed with HALG, and no peri-operative death occurred. There were no significant differences in the incision length [(7.0 ± 0.2) cm vs. (6.9 ± 0.3) cm], the operative time [(170.9 ± 33.8) minute vs. (174.6 ± 22.4) minute], dissected lymph node number (17.6 ± 7.5 vs. 17.1 ± 5.8) and post-operative complications [(6.5%(7/108) vs. 8.1%(7/86)] between the reverse group and cabbage group (all P>0.05). However, less blood loss [(204.6 ± 98.2) ml vs. (259.1 ± 122.6) ml, P<0.01] and shorter postoperative hospital stay [(9.0 ± 1.7) day vs. (10.5 ± 4.0) day, P<0.01] were observed in reverse group as compared to cabbage group. During 1 to 6 months follow-up, no death case was found in reverse group, while 1 case died due to upper gastrointestinal bleeding 48 days after operation in cabbage group.

CONCLUSIONEfficacy is similar between the two HALG procedures in lymph node dissection, while reverse procedure has certain advantages, such as less blood loss and faster recovery.

To detect the cellular immunity state of New Zealand white rabbit immunized by pig type II collagen. The New Zealand white rabbit was immunized by type II collagen for sixty days. The plasma was collected at a regular interval and the anti-type II collagen antibodies were examined. At the sixtieth day, the peripheral circular lymphocytes and the lymphocytes separated from spleen cells of rabbit and lymph nodes were collected and were stimulated by type II collagen in vivo again. The regulation of reactive cellular proliferation caused by the stimulation was detected. The experiment samples were divided into two groups. The first group was the positive control group by adding different concentrations of PHA and the non-specific immunity was assayed. The different concentrations of type II collagen were added to the second group and the specific immunity was assayed. The lymphocytes of normal rabbits showed proliferation by PHA stimulation but no proliferation by the first stimulation of type II collagen. Obvious proliferation due to the stimulation of both PHA and type II collagen in the immunized rabbit were observed. It shows that certain concentration of heterogeneous collagen may cause an increase of anti-type II collagen antibody in immunized rabbit and may cause a proliferation of lymphocytes in rabbit spleen and peripheral blood. The heterogeneous type II collagen causes cellular immunity in vivo.

Objective To investigate distribution and antimicrobial resistance among nosocomial pathogens from 13 teaching hospitals in China in 2009. Methods Non-repetitive pathogens from nosocomial BSI, HAP and IAI were collected and sent to the central lab for MIC determination by agar dilution method.WHONET5.6 software was used to analyze the data. Results A total of 2 502 clinical isolates were collected. The top three pathogens of BSI were Escherichia coli [27. 1% (285/1 052 )] , coagulase-negutive staphylococcus [12. 6% ( 133/1 052)] and Klebsiella pneumoniae [10. 8% ( 114/1 052)]. The top three pathogens of HAP were Acinetobacter baumannii [28. 8% (226/785)], Pseudomonas aeruginosa [16. 1% (126/785)] and Klebsiella pneumoniae [14.6% (115/785 )] . The top three pathogens of IAI were Escherichia coli[31.0% ( 206/665 )], Klebsiella pneumonia [11.3% ( 75/665 )] and Enterococcus faecium [10. 8% (72/665)]. Against Escherichia coil and Klebsiella spp. , the antimicrobial agents with higher than 80% susceptibility rate included imipenem and meropenem (98. 1%-100% ), tigecycline (95.3%-100% ), piperacillin-tazobactam ( 88.6% -97. 1% ) and amikacin ( 88. 3% -92. 5% ). Against Enterobacter spp. , Citrobacter spp. and Serratia spp. , the susceptibility rates of tigecycline were 93.5% -100% whereas the value of imipenem and meropenem were 92.9% -100%. Other antimicrobial agents with high activity included amikacin ( 85.2% -96. 7% ), pipcracillin-tazobactam ( 82.4% -96.4% ), cefepime ( 79. 6% -96. 7% ) and cefoperazonc-sulbactam (78. 7%-90. 0% ). Polymyxin B showed the highest susceptibility rateagainst Pseudomonas aeruginosa ( 100% ), followed by amikacin ( 81.9% ) and piperacillin-tazobactam (80.1% ). Polymyxin B also showed the highest susceptibility rate against Acinetobacter baumannii (98. 8% ), followed by tigecycline (90. 1% ) and minocycline (72. 0% ). The incidence of carbapenemresistant Acinetobacter baumannii was 60. 1%. The MRSA rate was 60. 2% and the MRSCoN rate was 84. 2%. All Staphylococcus strains were susceptible to tigecycline, vancomycin, teicoplanin and linezolid except for one isolate of Staphylococcus haemolysis with intermediate to teicoplanin. Two Enterococcus faecalis isolates which were intermediate to linezolid and one Enterococcus faecium isolate which was resistant to vancomycin and teicoplanin was found in this surveillance, while the MICs of tigecycline against these three isolates were 0. 032-0. 064 μg/ml. Conclusions Tigecycline, carbapenems, piperacillin-tazobactam,amikacin and cefepime remain relatively high activity against nosocomial Enterobacteriaceae. Pseudomonas aeruginosa exhibite high susceptibility to polymyxin B, while Acinetobacter baumanni shows high susceptibility to polymyxin B and tigecycline. Tigecycline, vancomycin, teicoplanin and linezolid remain high activity against nosocomial gram-positive cocci.
