OBJECTIVE: To study the status quo and features of serious ADR case in our hospital in order to improve the rational use of drug. METHODS: A total of 215 cases of serious ADR collected in our hospital in 2008 were evaluated and analyzed statistically, according to causality of ADR criteria. RESULTS: Sex and age have nothing to do with serious ADR. The ADR were predominantly induced by antimicrobial drugs accounting for 28.21% (n=101), followed by antipyretic,analgesics and anti-inflammatory drugs and antirheumatic 12.85% (n=46) and TCM preparation 11.73% (n=42). Organs and systems involved in ADR were characterized by the damage of skin and its appendants (33.49%, n=73), followed by liver lesion in 70 cases (32.11%). 160 improved cases, 54 cured cases and 1 sequela cases were include in 215 cases of serious ADR reports. CONCLUSION: Several factors result in serious ADR,so rational use of drug should be enhanced to reduce and avoid occurrence of ADR and guarantee the safety and effectiveness of drug therapy.

Mucosa-associated lymphoid tissue (MALT} lymphoma is a low grade B-cell lymphoma arising from MALT of extra-nodal. A link of Helicobacter pylori (HP) infection with gastric MALT lymphoma was confirmed in the early years. Currently, growing evidence indicates that development of non-gastric MALT lymphoma is also associated with infections by microbial pathogens. t(l1;18)(q21;q21)、t(l;14)(p22;q32) and t (14;18)(q32;q21) are specifically associated with MALT lymphoma, which occur at variable incidences in MALT lymphoma of different sites. The oncogenic activity of these three chromosome translocations is linked by antigen receptor-mediated NF-κB activation.In addition, a number of novel genetic abnormalities have been recently identified in MALT lymphoma. The findings of these microbial pathogens and molecular genetics would be helpful in better understanding the pathogenesis of MALT lymphoma and also useful for the diagnosis at early stage and proper treatments of MALT lymphoma.

Objective To study the causes of conversion to open surgery in patients receiving gynecological laparoscopic operations. Methods From January 2002 to December 2007,totally 2630 patients received gynecological laparoscopy in our hospital; 45 of them were converted to open surgery. The data of the 45 cases were analyzed. Results The causes of conversion to open surgery included uterus myoma located at specific locations (25 cases,55.6%),severe pelvic-abdominal adhesion (10 cases,22.2%),uterine horn pregnancy (3 cases,6.7%),ovarian tumors (3 cases,6.7%),surgical injury (3 cases,6.7%) ,and adenomyoma with requirement for uterus conservation (1 case,2.2%). Conclusions Peculiar locations of uterine myoma and severe pelvic-abdominal adhesion are the main causes of conversion to open surgery during gynecological laparoscopy. Detailed preoperative evaluation can decrease the rate of the conversion rate. Right timing of the conversion may reduce complication rate.

Objective To further study on the chemical constituents in the peels of Citrus changshan-huyou.Methods The chemical constituents were separated by repeated silica gel column chromatography,the structures were determined by spectral analyses.Results Ten compounds were obtained and identified as huyoujiasu(2'-hydroxy-malonyl-3,4-dihydroxybenzoic acid,Ⅰ),3'-hydroxy-4',5,6,7,8-pentamethoxyflavone(Ⅱ),eriodictyol(Ⅲ),tetracosanoic acid(Ⅳ),glyceryl dodecanoate(Ⅴ),neoeriocitrin(Ⅵ),naringin(Ⅶ),neohesperidin(Ⅷ),4-methoxy-3-hydroxybenzoic acid(Ⅸ),and 3,4-dihydroxybenzoic acid(Ⅹ).Conclusion 2'-hydroxy-malonyl-3,4-dihydroxybenzoic acid is a new compound and the above ten compounds are obtained from this plant for the first time.

Objective To compare anatomic resection (AR) and non-anatomic resection (NAR)for hepatocellular carcinoma (HCC) as a factor in preventing intra-hepatic recurrence and local recurrence after the initial surgical procedure.Methods A systematic review and Meta-analysis of nonrandomized trials comparing anatomic resection with non-anatomic resection for HCC published from 1990to 2010 in PubMed and Medline,Coehrane Library,Embase,and Science Citation Index were searched.Intra-hepatic recurrence,including early and late recurrence,and local recurrence were primary outcomes.5-year survival and 5-year disease-free survival were secondary outcomes.Pooled effect was calculated by utilizing either fixed effects model or random effects model.Result Eleven nonrandomized studies including 1576 patients were identified and analyzed.810 patients were in the AR group and 766 were in the NAR group.Patients in the AR group were characterized by lower prevalence of cirrhosis,more favorable hepatic function,and larger tumor size and higher prevalence of macrovascular invasion compared with patients in the NAR group.Anatomic resection significantly reduced the risks of local recurrence (OR,0.27; 95％ CI,-0.17～0.43; P＜0.001) and achieved a better 5-year disease-free survival (OR,2.10; 95％ CI,-1.41 ～3.12; P=0.001) in HCC patients.Also,anatomic resection was marginally effective in decreasing early intra-hepatic recurrence.However,anatomic resection was not advantageous in preventing late intra-hepatic recurrence.No significant differences were found between the AR and NAR groups with respect to postoperative morbidity,mortality,and length of hospitalization.Conclusion Anatomic resection was recommended to be superior to non-anatomic resection in reducing the risks of local recurrence,early intra-hepatic recurrence and achieving a better 5-year disease-free survival in HCC patients.

Objective To compare the effects of honey dressing and silver sulfadiazine dressing for wound healing in burn patients by Meta-analysis.Methods All the randomized controlled trials were collected by searching many kinds of databases in or out of the country to compare honey dressing with silver sulfadiazine dressing for wound healing in burn patients.Review Manager 5.2 was used to analyze the effects.Results Six randomized controlled trials (RCT) were included.Honey dressing was much better than silver sulfadiazine dressing for burn wounds,while there were no significant differences in positive rate of wound swab culture and healing days.Conclusions It can be proved that honey dressing has an advantage over silver sulfadiazine dressing in the wound healing days within 21 and final outcome.Whether honey dressing is superior to silver sulfadiazine dressing in antibacterial effects and healing days remains to be studied with adequate,powerful,high quality randomized controlled trials.

Objective In order to provide information for the health administration and the price authorities to establish the reasonable price,the practical cost of special nursing of the chronic wound be analyzed,and be compared with the present charge,and the deviation be studied.Methods The cost of nursing care for all items was measured,recorded and collected,then calculating the special nursing cost for chronic wound using the method of ladder sharing the project cost.Rusults The true cost on a single special care for chronic wound was (29.42±9.29)yuan,and it reached 2.5 times of present charge ( 12 yuan).Conclusions The present charge on the special care for chronic wound was seriously deviated from the practical cost,and the labor value of special care of nurses could not be embodied.

Objective To evaluate the diagnostic efficacy of MRS in prostate cancer based on sextant localization. Methods There were 110 patients, 54 patients with pathologically confirmed prostate cancer and 56 patients confirmed non-prostate cancer proved by ultrasound guided systemic biopsy. The (choline + creatine)/citrate (CC/C) value in each voxel and ratio of positive voxel (PVR) in sextant localization were measured. The ROC analysis was used to evaluate the diagnostic efficacy of CC/C in single voxel and PVR in sextant localization. Results There are 1673 and 2426 voxel in prostate cancer and non-prostate cancer respectively. The median of CC/C in cancer sextants was 2. 137; the median of CC/C in noncancer sextants was 0. 600. The difference of these two groups was statistically significant (Z = -41.7, P < 0. 01 ). The diagnostic sensitivity was 81.4% ( 1362/1673 ), the specificity was 83.1% (2018/2426), and the accuracy was 82.4% [ (1362+2018)/4099] for prostatic cancer with the cutoff point 0. 911 of the CC/C value. The median of PVR in cancer sextants and noncancer sextants were 1 and 0 respectively, the difference of PVR was statistically significant (Z = -11.7,P < 0.01 ). The diagnostic sensitivity was 77. 5% (148/191), the specificity was 76. 9% (247/321), and the accuracy was 77. 1% [ ( 148 + 247 )/ 512] for prostatic cancer with the cutoff point 0. 519 of the PVR. Conclusion Detecting the cutoff point of the CC/C value in single voxel and the PVR in sextant localization may be valuable in the diagnosis of prostate cancer.
