220.6 ?mol/L in serums.Conclusions TORCH infection is common in infantile hepatitis in hospital.The infection rates caused by CMV are higher than those caused by HSV,TOX,RV and the rate caused by TOX is lower than others,and then the injury of liver caused by CMV is more severe than others.Neonates less than 7 days always have more organs injuried than the elders.

OBJECTIVETo study the effects of Chinese materia medica (CMM) combined chemotherapy on the recurrence, metastasis, and the disease free survival (DFS) of stage II and III colorectal cancer (CC) patients after radical cure.

METHODSRecruited were 366 inpatients and outpatients with stage II and III colorectal cancer (CC) from Changhai Hospital, Second Military Medical University, and Tumor Department of Longhua Hospital, Shanghai University of Traditional Chinese Medicine from January 2002 to December 2008. A non-randomized concurrent control method was adopted. Patients were assigned to the combination group (treated by CMM + chemotherapy, 189 cases) and the chemotherapy group (177 cases) according to whether they were willing to receive the CMM treatment for more than 6 successive months. By using follow-ups at clinics, by letter, and by telephone, the DFS, 1-, 2-, 3-, and 5-year DFS ratios were observed. The correlations between DFS and the gender, age, tumor location, staging of clinical pathology, pathological type, chemotherapeutic cycle, radiotherapy, CMM treatment, end point event (recurrence and metastasis) were analyzed.

RESULTSThe recurrence or metastasis occurred in 145 cases (39. 61%) of the 366 patients. Of them, local recurrence occurred in 17 cases (11.72%), liver metastasis in 45 cases (31.03%), lung metastasis in 52 cases (35.86%), and metastasis in other parts in 53 cases (36.55%). Results of one-factor analysis showed six factors such as the tumor location, pathological type, staging of clinical pathology, chemotherapeutic cycle, radiotherapy, and CMM treatment were correlated with the DFS, showing statistical difference (P<0.01, P<0.05). Results of multifactor analysis showed staging of clinical pathology, chemotherapeutic cycle, and CMM treatment were correlated with the DFS, showing statistical difference (P<0.01). Results of stratified study on the staging of clinical pathology indicated that the primary tumor location (P=0.016) and the pathological type (P=0.047) were the independent predictors for DFS of stage II CC. The median DFS of the two groups could not be calculated. Results of stratified study on the stages of clinical pathology indicated that CMM treatment (P=0.000) and chemotherapeutic cycle (P=0.017) were independent predictors for DFS of stage III CC. As for comparing the composition ratio of the two therapeutic cycles, results showed the baselines of the chemotherapeutic cycle of the two groups were balanced. Further comparison showed the median DFS for the chemotherapy group at stage III was 24. 16 months, while it could not be calculated in the combination group. The DFS, 1-, 2-, 3-, and 5-year DFS ratios were 92%, 72%, 61%, and 59%, respectively in the stage III CC combination group, while they were 74%, 50%, 36%, and 20%, respectively in the stage IlI CC chemotherapy group.

CONCLUSIONCMM combined chemotherapy could prolong the DFS of stage III CC patients after radical cure.

OBJECTIVETo investigate the difference of serum high molecular weight alkaline phosphatase (HMAP) levels between biliary atresia (BA) and neonatal hepatitis (NH), and to develop a new differential method and early diagnostic indicators for cholestatic jaundice in neonates.

METHODSTotally 31 patients with cholestatic jaundice seen between Aug. 2000 and Feb. 2002, including 15 cases with BA, 16 cases with NH, 30 healthy infants and 30 infants with non-cholestatic jaundice were enrolled in this study. Serum samples were obtained from each subject by using venipuncture. The samples were stored at -80 degrees C and analyzed within 6 months. A murine hybridoma producing monoclonal antibody to human high molecular weight alkaline phosphatase (MoAb HMAP-1) was prepared by using partially purified HMAP from human serum as the immunogen. The antibody did not cross-react with other alkaline phosphatase (ALP) isozymes. A monoclonal antibody immunocatalytic assay for HMAP in serum was developed by using MoAb HMAP-1 bound to nitrocellulose membrane discs. The serum total ALP (TALP) and gamma-GT were determined in the meantime, the hepatobiliary ultrasonography and scintigraphy were performed too. The data were analyzed with t test, chi-square test and percentage. Comparisons were made between BA and NH with their sensitivity and specificity in different methods.

RESULTSSerum HMAP was detected in 14 of 15 patients of BA, in 2 of 16 NH patients, while in none of the healthy control group. The positive ratios of serum HMAP in BA and NH were 93.3% and 12.5%, respectively (P < 0.005). The sensitivity and specificity of serum HMAP in BA and NH were 93.3% and 87.5%, respectively. The sensitivity and specificity of TALP, gamma-GT and hepatobiliary scintigraphy were 80.0%, 73.3%, 86.7% and 62.5%, 68.8%, 62.5%, respectively, which were clearly lower than those of serum HMAP.

CONCLUSIONSThe determination of serum HMAP was more sensitive and specific than the other methods tested. Therefore the method can be used as a useful indicator for cholestatic jaundice in neonates, although it needs further study.

OBJECTIVETo evaluate the efficacy and safety of ambroxol in the prevention of respiratory distress syndrome (RDS) in preterm infants.

METHODSElectronic searches were performed in the Cochrane Library, PubMED, EMBASE, Chinese CBM, Chinese VIP Database, Chinese Wanfang Database and Chinese CNKI Database up to the year of 2009 for randomized controlled trials (RCT) on ambroxol for the prevention of RDS in preterm infants. The meeting articles related to the RCT were manually searched in Pediatrics and Pediatric Research. Meta analysis was performed for the results of homogeneous studies by the Cochrane Collaboration's software RevMan 5.0.17.

RESULTSSix RCTs involving 823 preterm infants were included, and the quality assessment for the trials demonstrated 1 article as A class, 1 article as B class and 4 articles as C class. The Meta analysis showed that ambroxol administration significantly reduced the incidence of RDS (OR=0.24, 95%CI: 0.15 - 0.64, P<0.01), bronchopulmonary dysplasis (BPD, OR=0.41, 95%CI: 0.23 - 0.75, P<0.01), intraventricular hemorrhage (IVH, OR=0.39, 95%CI:0.24 - 0.64, P<0.01), patent ductus arteriosus (PDA, OR=0.33, 95%CI: 0.17 - 0.67, P<0.01) and pulmonary infection (OR=0.24, 95%CI:0.14 - 0.38, P<0.01). No adverse events related to the ambroxol treatment were reported.

CONCLUSIONSThe current evidence shows that early use of ambroxol can reduce the risk of RDS, BPD, IVH, PDA and pulmonary infection in preterm infants.

OBJECTIVETo investigate the dynamic variation and action mechanism of sICAM-1 and p38 mitogen-activated protein kinases (MAPK) signal transduction in human severe trauma and resuscitation, as well as the effect of lactated Ringer's solution(LR), 7.5% sodium chloride solution(HS) and 20% albumin injection(ALB) on the incidence and mortality of multiple organ dysfunction syndrome (MODS).

METHODSSeventy-two severe trauma patients (ISS score 16-43) were divided into ISS < or = 25 and ISS > 25 groups (each group was subdivided into LR, HS and ALB groups). ELISA was used to measure the concentration of sICAM-1. Western blot was used to measure the expression of p38 MAPK.

RESULTSCompared with LR group, the transfusion volume needed for maintaining systolic blood pressure > or = 90 mm Hg was significantly decreased in HS and ALB groups (P < 0.05). Compared with the control group, the concentration of blood sICAM-1 and the expression of p38 MAPK was elevated from 4 to 48 hours after trauma in all experimental groups (P < 0.05-0.01). At 4, 12, and 24 hours, there was significant correlation between the expression of p38 MAPK and sICAM-1 (P < 0.01). Compared with LR group, sICAM-1 and p38 MAPK in HS and ALB groups were decreased (P < 0.05). sICAM-1 and p38 MAPK were significantly higher in the group of ISS > 25 than that of ISS < or = 25 (P < 0.05). MODS incidence and mortality were significantly higher in the group of ISS > 25 than that of ISS < or = 25 (P < 0.05). MODS incidence and mortality were lower in HS and ALB groups than LR group (P < 0.05).

CONCLUSIONSThe up-regulation of polymorphonuclear neutrophil-endotheliocytes (PMN-EC) adhesion may be due to the increased sICAM-1 expression during severe trauma. The up-regulation of sICAM-1 expression is correlated with the activation of p38 MAPK. During severe trauma, the levels of sICAM-1 and p38 MAPK, as well as the incidence and mortality of MODS are lower when HS and ALB are used than single lactated LR solution is used.

OBJECTIVETo construct a three plasmids lentiviral vector containing canine coagulation factor IX (cFIX) gene with ubiquinone promoter (PUB) and observe the expression of cFIX gene.

METHODSLentivirus was generated by transient three-plasmid transfection, namely, the VSV-G envelope expression cassette, the delta NRF packaging plasmid and the PTK 164 plasmid. Viral particles were used to infect the target cell, third passage mesenchymal stem cells (MSCs) and 293T cell respectively at MOI 3: 1. The cFIX activity was detected in cultured cells with one-stage clotting assay.

RESULTSThe MSCs were obtained in vitro. The lentivirus infected MSCs and 293T cells all expressed the active factor IX with the activity of (26.30 +/- 2.10)% and (19.70 +/- 1.53)%, respectively, which are significantly higher than that of control (1.00 +/- 0.05)%.

CONCLUSIONSThe lentiviral vector of three plasmids with ubiquinone promoter (PUB) was constructed and can transfect the MSCs and 293T cells.
