OBJECTIVE:
To evaluate the effect of herceptin(trastuzumab) plus adjuvant chemotherapy on the prognosis of patients with human epithelial growth factor receptor 2 (HER2) positive early-stage breast cancer by Meta-analysis.
METHODS:
Search all of randomized clinical trials (RCTs) on herceptin plus adjuvant chemotherapy for HER2 positive early-stage breast cancer in MEDLINE, EMBase, Cochrane library, Clinical Trails, ASCO Conference data, CHKD, Wanfang Database, VIP information, scholar.google.com and SIGLE. A Meta-analysis was carried out by collecting information based on the inclusion and exclusion criteria from all papers available.
RESULTS:
The Meta-analysis included 4 trials. A total of 9116 patients were included in the analysis(4555 in the study group and 4561 in the control group). There were statistical differences between the study group(herceptin plus adjuvant chemotherapy) and the control group(adjuvant chemotherapy) in the disease-free survival rate [relative risk(RR)=1.08, 95% CI, 1.06-1.09, P<0.001], the overall survival rate(RR=1.01, 95% CI, 1.01-1.02, P=0.0003), the distant recurrence rate(RR=0.49, 95% CI, 0.42-0.57, P<0.001), and the cardiac events rate (RR=3.93,95% CI, 1.03-15.06, P=0.05).
CONCLUSION
Herceptin plus adjuvant chemotherapy can improve the disease-free survival rate and the overall survival rate, decrease distant recurrence rate of patients with HER2 positive early-stage breast cancer, but may cause heart toxicity, especially when combined with anthracycline (doxorubicin).

Objective To determine the status of false-positive report of congenital syphilis (CS),to analyze the possible causes of mis-diagnosis.Methods Basic information on CS in Shanghai in the past five years was collected.We identified infants diagnosed with CS and followed up the sero- logical reactivity of those patients and their mothers.The serological reactivity[rapid plasmin reagin (RPR)and treponema palidum hemagglutination assay(TPPA)]of infants was followed-up for up to 24 months,or until both antibodies turned to negative.The medical history of the mothers was col- lected,and their sera were examined for syphilitic antibodies.Results Total 99 infants diagnosed with CS were recruited. The major diagnostic method was treponemal antibody detection.Only 31.3% of the 99 infants exhibited clinical symptoms or syphilis-like symptoms at delivery.The cumu- lative RPR loss rates of the infants were 44.2%,64.0%,72.7%,83.9% and 87.1% at 1-3,3-6,6- 12,12-18 and 18-24 months after birth,respectively.The cumulative TPPA loss rates were 1.1%, 18.6%,44.6%,66.7% and 74.4% for 1-3,3-6,6-12,12-18 and 18-24 months after birth,respec- tively.TPPA remained positive in all mothers with syphilis.Conclusion The diagnosis of congenital syphilis determined solely by the positive tests of RPR and TPPA is unreliable and can be misdiagno- sis.The diagnosis and management of congenital syphilis should be urgently improved,and that the profes- sional health institutions should perform and closely monitor the quality controls in the diagnosis of CS and standardize the intervention strategy of maternal syphilis.

BACKGROUND: Adipose-derived mesenchymal stem cells (ADMSCs) have been reported to improve wound healing. However, type I collagen secreted by ADMSCs will contribute to scar formation. Therefore, inhibiting type I collagen secretion from ADMSCs will strengthen its clinical application. OBJECTIVE: To investigate the effect of 1,25(OH)2D3on secretion of type I collagen by ADMSCs and its mechanism. METHODS: Human ADMSCs were isolated by collagenase digestion, and identified by flow cytometry. ADMSCs at passage 4 were cultured in DMEM/F12 medium containing different concentrations of 1,25(OH)2D3(10-7, 10-8, 10-9, 10-10and 0 mol/L) respectively for 4 days. Then, the concentration of type I collagen in cell supernatant was measured by ELISA. Real-time PCR and western blot were used to detect the expression of Smad3 at mRNA and protein levels and phosphorylated protein Smad3 level in ADMSCs cultured with and without 1,25(OH)2D3. To analyze the contribution of Smad3 to the effect of 1,25(OH)2D3, Smad3 inhibitor was added to culture medium 30 minutes before adding 1,25(OH)2D3, and type I collagen in cell supernatant was detected by ELISA at 4 days after addition of SMAD3 inhibitor. RESULTS AND CONCLUSION: 1,25(OH)2D3inhibited the secretion of type I collagen by ADMSCs in a dose-dependent manner. The results of real-time PCR and western blot showed that the expression of Smad3 was upregulated by 1,25(OH)2D3, and the results of western blot showed that the phosphorylated Smad3 protein level in ADMSCs was significantly increased by 1,25(OH)2D3. Moreover, the inhibition of type I collagen secretion by 1,25(OH)2D3could be blocked by Smad3 inhibitor. These results indicate that 1,25(OH)2D3can inhibit the secretion of type I collagen from ADMSCs by up-regulating the expression of Smad3.

OBJECTIVETo explore the effects of 50 Hz sinusoidal magnetic fields (MF) on secretion function of primary human villous trophoblasts in vitro, and the interference effect of "noise" MF.
METHODSThe trophoblasts were isolated from human villus by trypsin digestion and incubated in DMEM medium.Then the trophoblasts were exposed to 0.4 mT 50 Hz MF and/or "noise" MF respectively for different durations. Each exposure group was matched with one control group which was from the same villus and cultured with the same condition except the MF exposure. The concentrations of human chorionic gonadotropin (HCG) and progesterone in the culture medium were measured by immunofluorescence. Statistical significance of differences between means was determined by one way-ANOVA with P<0.05 considered significant.
RESULT50 Hz MF inhibited the HCG and progesterone secretion significantly when exposure for 72 h (compared with control group, P<0.05). There was no significant change of HCG and progesterone secretion when trophoblasts were exposed to 0.4 mT "noise" MF within 72 h (compared with control group, P>0.05). However, by superimposing the "noise" MF, the inhibition of HCG and progesterone secretion of trophoblasts induced by 50 Hz MF was eliminated.
CONCLUSIONThe exposure to 50 Hz MF for long period could inhibit trophoblasts secreting HCG and progesterone, and the "noise" MF with the same intensity could eliminate the effects induced by 50 Hz MF.

OBJECTIVETo investigate the mechanism and the accelerating effect of rhEGF and rhbFGF on wound healing.
METHODSTwelve New Zealand rabbits with 72 incised wounds on ventral side of 24 ears were randomly divided into two therapeutic groups (rhEGF of 10 ug/cm(2) and rhbFGF of 100 AU/cm(2)) and a control group (1% silver sulfadiazine cream, SD-Ag). The general conditions of the wound healing was observed grossly. Biopsies were harvested at different time points for the pathomorphological examination, the electron microscopic examination, and for assessment of integrin beta1 mRNA expression by in situ hybridization.
RESULTSThe expressions of integrin beta 1 mRNA in two therapeutic groups were significantly higher than that of control group. The quality of the wound healing was improved in therapeutic group with its healing time shortened when compared with that in control group (P < 0.05). There was an obvious difference in the number of fibroblasts and capillary gemmules between the therapeutic and control groups (P < 0.05).
CONCLUSIONThe wound healing and quality could be improved by both rhEGF and rhbFGF, but rhbFGF seemed better to be employed during the early and middle stages of the wound repair for the growth of granulation tissue, while rhEGF should be applied at the late stage of wound repair to accelerate the re-epithelialization of the wound. Combined application of rhEGF with rhbFGF according to time effect could be more beneficial to the wound repair.

BACKGROUNDMutations in the fibrillin-1 gene have been identified in patients with Marfan syndrome (MFS). This study aimed to identify the molecular defects in the fibrillin-1 gene in a Chinese family with Marfan syndrome, accompanied by aortic aneurysms/dissection.
METHODSTwo patients and one non-carrier in the family underwent complete physical, ophthalmic, and cardiovascular examinations. Genomic DNA was extracted from leukocytes of venous blood of these individuals in the family as well as 50 healthy normal controls. Polymerase chain reaction amplification and direct sequencing of all 65 coding exons of fibrillin-1 gene were analyzed.
RESULTSWe found a novel mutation (c.8547T > G, p.Tyr2849X) in exon 65 of fibrillin-1 gene in a Chinese proband with Marfan syndrome, accompanied by aortic aneurysms/dissection. Sudden death at a young age of affected members was seen due to aortic aneurysms/dissection. By evaluating genotype-phenotype correlations of patients with mutations in the 3' end of fibrillin-1 gene (exons 64 and 65), we also found that the presence of nonsense mutations occurring in exons 64 and 65 appeared to be an indicator of early-onset aortic risk and sudden death.
CONCLUSIONSThese results expand the mutation spectrum of fibrillin-1 gene and help in the study of the molecular pathogenesis of Marfan syndrome, indicating that mutations occurring in the 3' end of fibrillin-1 gene may play an independent functional role in the pathogenesis of Marfan syndrome.

OBJECTIVETo investigate the effects of dopamine and norepinephrine on the renal function in the patients with septic shock.
METHODSEighty-seven patients with septic shock were divided into three groups (group A, B, C) according to the biggest infusing rate of norepinephrine, with the infusing rate of 0.5 - 0.9, 1.0 - 1.5, 1.6 - 2.0 microg x kg(-1) x min(-1), respectively. Mean arterial blood pressure (MAP), heart rate (HR), urine output, blood urea nitrogen (BUN), creatinine (CRE), urine albumin (U-ALB) and urine beta(2)-microglobulin (Ubeta(2)-MG) as well as APACHE III score in all the patients were detected.
RESULTSBefore anti-shock therapy was given, hypotension, tachycardia and oliguria occurred in all the 87 patients, and CRE, BUN, U-ALB, Ubeta(2)-MG and APACHE III score were abnormal in most cases. With the anti-shock therapy, MAP, HR, urine output and BUN, CRE in all patients returned to normal levels gradually, and U-ALB, Ubeta(2)-MG levels and APACHE III score also restored but still remained abnormal.
CONCLUSIONSThe first aim of treating septic shock should be restoring the organ blood supply, and based on volume resuscitation, dopamine, noradrenaline and other vasoactive drugs could be combined to maintain circulatory stability.
