Objective To explore the effective method of treating childhood acute aplastic anemia(AAA) by overviewing the curative effect of therapeutic alliance to the children diagnosed as AAA with immunodepressants.Methods Retrospective analysis was performed on 13 patients diagnosed as AAA,who were treated by high dose of methyllprednisolone,antilymphocyte globulin,ciclosporin A,large dose of gamma globulin,granulocyte colony-stimulating factor and blood transfusion in 4 years.Results Among 13 cases,9 cases were healing well on the whole,one was relieved,one was improving,two were ineffective(one of them was dead).In 9 cases who were healing,WBC took(24.60?8.86) days to reach 4?10~9/L,hematoglobin took(152.22?68.88) days to reach normal and platelet took(125.55?55.86) days to reach 80?10~9/L.During the procedure of treating,infection appeared in 7 cases,the ALT and AST was high in 2 cases,hypoproteinemia and edema in 1 case,gross hematuria in 2 cases,gingival hyperplasia obviously and dedentition in 1 case.Conclusion Therapeutic alliance with immunodepressants to childhood AAA is a safe and effective method.

OBJECTIVETo study the factors influencing short-term prognosis of tuberculous meningitis (TBM) in children.

METHODSThe clinical data of 137 hospitalized children with TBM between January 2007 and February 2011 were retrospectively reviewed. A total of 30 potential factors influencing short-term prognosis of TBM were evaluated by univariate analysis and multivariate logistic regression analysis.

RESULTSClinical staging showed that of the 137 children 21 cases (15.3%) were in the early stage, 67 cases (48.9%) in the medium stage and 49 cases (35.8%) in the late stage of TBM. The univariate analysis revealed 8 factors associated with a poor short-term prognosis: clinical stage of TBM (late), coma, positive Babinski signs, cranial nerve involvements, paralysis, seizures, obvious abnormalities in brain computed tomography (CT) or magnetic resonance imaging (MRI) and elevated protein concentrations in cerebrospinal fluid (CSF). Factors associated with a favourable short-term prognosis for TBM included glucocorticoid steroids therapy, positive reaction of PPD skin test and an increased length of stay in hospital. Multivariate logistic analysis revealed two independent risk factors for a poor short-term prognosis: clinical stage of TBM (late) (OR: 11.168, 95%CI: 3.521-35.426) and positive signs of meningeal irritation (OR: 4.275, 95%CI: 1.043-17.521). An increased length of stay in hospital was shown as a favorable factor (OR: 0.893, 95%CI: 0.825-0.968).

CONCLUSIONSLate-stage TBM and positive signs of meningeal irritation suggest a poor prognosis, while an appropriately longer length of stay in hospital may contribute to a favorable short-term prognosis for children with TBM.

ObjectiveTo identify the correlation factors for urosepsis shock after endourology surgery and analyze its clinical characteristics.MethodsFifty-eight patients with urosepsis without shock and 15 patients with shock were studied.Factors which may be correlated with the development of sepsis were analyzed including age,sex,ASA physical status,history of urinary tract infection,preoperative leukocyturia,urine bacteria culture,prophylactic antimicrobial treatment,pyonephrosis,type of surgery,duration of operation,blood leukocyte count and concentration of creactive protein at the end of surgery,the time when the signs of infection (shivering,agitation,nausea or vomiting) first appeared.Changes in BP in patients with urosepsis shock,scores for multiple organ dysfunction syndrome as well as treatment and prognosis were also recorded.ResultsFemale sex and early emergence of signs of infection after surgery were correlated with urosepsis shock.Abrupt hypotension was usually the first manifestation of urosepsis shook.The lowest systolic BP was positively correlated with the time when diagnosis of shock was made and negatively correlated with the length of ICU stay and the highest multiple organ dysfunction syndrome scores but not correlated with shock correction time.All patients with urosepsis shock recovered completely when discharged from hospital.ConclusionFemale sex and patients with early emergence of signs of infection are prone to develop urosepsis shock after endourology operation.The prognosis of urosepsis shock is good if diagnosed and treated in time.

OBJECTIVETo explore the effect of Danshensu on the lipid metabolism of hyperlipidemic rats.

METHODSixty clean male SD rats were selected. Twelve of them were selected in the basic control group and fed with common foods, and the remaining rats were fed with the high-fat feeds. After the successful modeling, they were randomly divided into the high-fat control group and low dose (10 mg x kg(-1) x d(-1)), medium dose (20 mg x kg(-1) x d(-1)) and high dose (40 mg x kg(-1) x d(-1)) Danshensu (dissolved in saline) groups. Both of the two groups were abdominally injected with the same volume of normal saline once a day for consecutively 30 days. The serum TG, TC, HDL-C and liver ACC1, FAS, HMGR, CPT-I mRNA expressions were detected.

RESULT AND CONCLUSIONDanshensu could inhibit the LDL-C level, timely clear redundant cholesterol and effectively regulate the lipid metablism of hyperlipidemic rats by reducing the TC content, decrease the fatty acid by reducing the FAS mRNA expression, and reduce the synthesis levels of endogenous cholesterol by inhibit the HMGR mRNA expression.

Objective To explore the application value of ultrasound-guided fine needle aspiration biopsy(FNAB) in diagnosing thyroid nodules of TI-RADS 4-6 categories.Methods A retrospective analysis was made on the pathologic data of 494 patients (totally 501 nodules) who underwent TI-RADS ultrasonographic stratification and ultrasound-guided FNAB.168 thyroid nodules of TI-RADS 4-6 categories were selected from 163 patients and classified into three groups:group T,TI-RADS 4A categories;group Ⅱ,TI-RADS 4B category; group Ⅲ,TI-RADS 5-6 category(the pathologically confirmed cases in category 6 had been removed).The ultimate pathologic findings were taken as golden standards to calculate the accuracy,sensitivity,specificity,positive predictive value of ultrasound-guided FNAB in the three groups.ROC curve was drawn to evaluate the diagnostic value of FNAB.Results The accuracy,sensitivity,specificity,positive predictive value of the ultrasound-guided FNAB in the three groups were listed as follows:group Ⅰ 74.4％,73.3％,75.0％,64.7％;group Ⅱ 83.9％,87.5％,71.4％,91.3％;group Ⅲ 89.3％,91.7 ％,75.0％,95.7 ％ respectively.The positive predictive values of the ultrasound-guided FNAB for group Ⅰ and group Ⅱ was higher than that of conventional TI-RADS classification criteria,so the difference was statistically significant; while the positive predictive values for group Ⅲ was close to the conventional ultrasound TI-RADS classification criteria,the difference was not statistically significant.Conclusions The combination application of TI-RADS classification criteria and FNAB can improve the accuracy of ultrasound diagnosis in group Ⅰ and group Ⅱ,and reduce the puncture rate of group Ⅲ.

Objective To systemically evaluate the clinical therapeutic effect and safety of traditional Chinese medicine on Kawasaki disease. Methods Through retrieval of the reports in PubMed, the Cochrane Library, China National Knowledge Internet (CNKI), VIP database, Wanfang database by computer, the correlative articles of clinically randomized controlled trials (RCTs) published in China during the period from 1990 to 2013 were collected, and their quality evaluation was made. All the articles were screened according to inclusion and exclusion criteria, in which interventions were traditional Chinese medicine therapy and conventional western treatment. The articles selected were assessed with the software of RevMan 5.2. Results There were 212 articles searched out, but only 13 articles, 656 children with Kawasaki disease were conformed to the inclusion criteria. The Meta analysis indicated that the total effective rate in the traditional Chinese medicine group was superior to the group treated with western medicine. The difference in the curative effects between the two groups had notable significance [odds ratio (OR) = 3.58, 95%confidence interval (95%CI) was 2.16-5.93, test for overall effect Z=4.94, P<0.000 01]. No difference was seen in the curative effect of improving coronary artery changes between the traditional Chinese medicine group and western medicine control group (OR=2.03, 95%CI was 0.74-5.62, test for overall effect Z=1.37, P=0.17). Conclusion The clinical therapeutic effect of traditional Chinese medicine on Kawasaki disease is superior to that treated by western medicine.

OBJECTIVETo study the distribution and antibiotic resistance of the isolated pathogens from children with infectious diarrhea in Guangzhou.

METHODSThe fecal samples of 2 409 children with infectious diarrhea between January 2006 and December 2007 were collected and cultured. Pathogenic bacterium were isolated and identified by biochemical and serological methods. The antibiotic susceptibilities were tested by the Kirby-Bauer method.

RESULTSA total of 448 isolates of pathogenic bacterium (18.6%) were obtained, including Shigella (n=159), enteropathogenic Escherichia coli (n=141), Salmonella (n=76), Vibrion (n=11), fungus (n=41), and C jejuni (n=20). All of isolates of the three major pathogenic bacterium, Shigella, enteropathogenic Escherichia coli and Salmonella, were susceptible to imipenem and less than 10% of the isolates were resistant to the third generation cephalosporins and beta-lactamase inhibitors. However, the isolates showed a high resistance to ampicillin and sulfamethoxazole/trimethoprim (>75%).

CONCLUSIONSShigella, enteropathogenic Escherichia coli and Salmonella were major pathogenic bacterium of diarrhea in children from Guangzhou. The major isolates were susceptible to imipenem, the third generation cephalosporins and beta -lactamase inhibitors, but were resistant to ampicillin and sulfamethoxazole/trimethoprim.

Background: Tumor markers are widely used in clinical practice and have become important indicators in assessing cancer progress. There is increasing concern that chemotherapy combined with traditional Chinese medicine has effects in decreasing the level of tumor markers. Objective: To investigate the effects of chemotherapy combined with Kangliu Zengxiao Decoction (KLZX), a compound Chinese herbal drug, on tumor markers carbohydrate antigen 50 (CA 50), cytokeratin 19 fragment (CYFRA21-1) and carcinoembryonic antigen (CEA) in patients with advanced non-small-cell lung cancer (NSCLC) and to explore the relationships between clinical efficacy and tumor markers. Design, setting, participants and interventions: Patients were included from Punan Hospital of Shanghai Pudong New District and Longhua Hospital between October 2008 and December 2009. Seventy-four subjects with advanced NSCLC were randomly assigned into treatment group (n=37) and control group (n=37). Patients in the control group were treated with chemotherapy alone while patients in the treatment group were treated with chemotherapy combined with KLZX. Chemotherapy of NP (vinorelbine + cisplatin) was given for two cycles and patients in the treatment group were administered with KLZX during chemotherapy. Main outcome measures: Levels of CA50, CYFRA21-1 and CEA before and after treatment were evaluated and the relationship between changes in levels of tumor makers and tumor size, clinical symptoms and living condition score (Karnofsky score) was analyzed. Results: No patients achieved a complete remission. The disease control rates (complete remission (CR)+partial remission (PR)+no change (NC)) were 89.20% (33/37) and 70.30% (26/37) in the treatment and control group respectively (P<0.05). The levels of CA50, CYFRA21-1 and CEA were clearly decreased in the treatment group after treatment (P<0.05) while also decreased in the patients without progression of disease. There were no obvious changes of CA50, CYFRA21-1 and CEA in the control group, and there was even a trend of increase. Furthermore, the improvement rates of clinical syndrome were 51% (19/37) vs 11% (4/37) (P<0.05) in the treatment group and control group respectively. The total response rates of quality of life were 91.89% (34/37) vs 56.76% (21/37) (P<0.01) in the treatment and control group respectively. Conclusion: Combined chemotherapy with KLZX in treating advanced NSCLC can acquire better stabilizing tumor foci, decrease levels of tumor markers and improve the clinical symptoms and Karnofsky score.

Objective To explore the expression of miRNA-181a (miR-181a) in patients with multiple myeloma (MM) and its effect on biological features of MM cells. Methods CD138+cells of bone marrow from 25 MM patients and 10 patients with hematological non-malignancies were purified by using immunomagnetic separation, and the expression of miR-181a in CD138+cells and MM cell lines including RPMI 8226, H929 and U266 were detected by real-time quantitative PCR. The effects of down-regulation and up-regulation of miR-181a expression on the biological characteristics of MM cells were studied with miR-181a antagomir and agomir. Results Compared with patients with hematological non-malignant diseases, the expression of miR-181a in CD138+ cells was upregulated in MM patients. Compared with CD138+ cells in hematological non-malignancies, high expressions of miR-181a were observed in RPMI 8226 and U266 myeloma cell line, while low expressions of miR-181a were observed in H929 cells. Down-regulation of miR-181a with 100 nmol/L miR-181a antagomir could inhibit the proliferation of U266 cells at 24,48 and 72 h [(67.1 ± 3.3) %vs. (50.5 ± 4.1) %, (71.5 ± 3.6) % vs. (52.3 ± 2.2) %, (78.1 ± 5.4) % vs. (69.5 ± 4.3) %, P < 0.05 respectively], whereas up-regulation of miR-181a with 100 nmol/L miR-181a agomir could significantly promote the proliferation of H929 cells at 24 h and 48 h [(21.2 ± 2.4) %vs. (38.5 ± 3.6) %, ( 61.3 ± 5.4) %vs. (82.2 ±6.9)%, P<0.01 respectively]. Cell cycle analysis showed that miR-181a antagomir made U266 cell cycle arrest in the G0/G1 phase. Meanwhile, susceptibility test results indicated that the apoptosis of U266 cells induced by doxorubicin, paclitaxel and 5-fluorouracil was increased when the proliferation of miR-181a expression was down-regulated with miR-181a antagomir. In migration assay, the data showed that down-regulation of miR-181a with miR-181a antagomir could inhibit the migration of U266 cells, and the proportion of migrated cells in the experimental group (62 ± 10) %was lower than that in the control group (89 ± 12) %(P< 0.05), whereas up-regulation of miR-181a with miR-181a agomir could improve the migration of H929 cells, and the proportion of migrated cells in the experimental group (242 ± 9) % was higher than that in the control group (98 ± 8)%(P<0.01). Conclusions The high expression of miR-181a expressed highly by MM cells may promote the proliferation, migration and drug resistance of myeloma cells, indicating that miR-181a could be an important prognostic biomarker candidate, and the application of gene silencing may improve the prognosis of MM.
