OBJECTIVE: To evaluate the efficacy and safety of telbivudine in preventing mother-to-infant HBV transmission in pregnant women who have positive HBsAg and HBeAg during the third trimester of pregnancy. METHODS: A total of 80 pregnant women, who had positive HBsAg and HBeAg with HBV DNA levels of ≥1 × 106 copies · mL-1 were divided into two groups: the treatment group and the control group. Each group comprised 40 cases. The subjects in the treatment group received telbivudine 600 mg once daily from the 28th weeks of pregnancy till delivery. The subjects in the control group did not receive telbivudine or other anti-virus drugs. The adverse reactions of the subjects in the treatment group were observed, and the serum HBV DNA levels in the two groups were measured at the 28th weeks of pregnancy, upon delivery and 6 months after delivery, respectively. The infants in the two groups received IM HBIG 200 IU immediately after birth and 1 month after birth. And both of the groups received IM hepatitis B vaccine 10 μg immediately after birth as well as 1 month and 6 months after birth. The serum HBsAg and HBV DNA levels in all infants were measured at birth, 6 months, and 12 months after birth, respectively. RESULTS: There was no significant difference in serum HBV DNA levels between the treatment group and the control group at the 28th weeks of pregnancy. The serum HBV DNA level immediately after delivery in the treatment group [(3.48±0.90) × 10 copies · mL-1] was significantly decreased compared with the control group [(6.96±0.94) × 10 copies · mL-1](P<0.05). There was no significant difference in HBV DNA levels between the treatment group and the control group 6 months after delivery. The rates of mother-to-infant HBV transmission in 12-month-old infants in the treatment group and the control group were 97.5% and 75%, respectively. The difference was statistically significant(P<0.05). No adverse reaction was found in the treatment group, and abnormal development was not found in the infants of the two groups. CONCLUSION: Telbivudine appears to be effective and safe in preventing HBV mother-to-infant transmission and has no influence on infant development.

Objective To explore the echocardiography characteristics of non-compaction of ventricular myocardium(NVM),and assess its value in the diagnosis of NVM.Methods Philips SONOS 5500 color Doppler ultrasound system with 2-4 MHz transducers was used in 9 patients with NVM.Results In all 9 patients,the presence of multiple trabeculations and multiple deep intertrabecular Space communicating with the ventricular cavity was demonstrated by color Doppler imaging.Both ventricles were involved in 1 patient,only the left ventricle in 7 patients,and right ventricle in 1 patient.Conclusions NVM has typical ultrasonic appearance on echocardiography.It Can find out the NVM manifestations even if patients do not have any symptoms.It is a reliable and convenient way for diagnosing NVM.

Objective No reports has been found to date on whether frequency compounding can improve elastographic image signal to noise ratio (SNRe) and how it affects elastogram performance.In this paper simulations investigation was carried out on transmit-side frequency compounding (TSFC)for elastography.Methods 50 mm×50 mm tissue model was simulated with two round hard inclusions of 10mm diameter uniformly distributed along the tissue central axial line,and their elasticity modulus were 10 times of the background.Then simulation of 3.5 MHz、5 MHz and 7.5 MHz probes were introduced to form compression elastography of the double-lesion model by quasi-static compression method (applied strain 1%).Then,sub-elastograms obtained by the combination of 3.5 MHz and 5 MHz,3.5 MHz and 5 MHz,3.5 MHz and 7.5 MHz were compounded,respectively.Results Before compounding,signal to noise ratio (SNRe) of the various sub-elastograms were 8.42,9.62,10.73,respectively,contrast to noise ratio (CNRe) were 11.35,14.82,18.37,respectively and axial resolutions were 9.83,9.82,9.81.After compounding elastograms,the SNRe were 11.82,13.05,19.45,CNRe were 22.31,27.63,56.12,while axial resolutions were 9.83,9.83,9.83.Conclusion Frequency compounding elastograms have higher SNRe and CNRe than any sub-elastogram before compounding and have no axial resolution loss.The TSFC can improve elastogram performance efficiently and frequency compounding for elastography enhancement is feasible.

Abdominal multivisceral transplantation is a new and proved effective therapeutic methods for two or more terminal abdominal organs. Upper abdominal exenteration(resection of the liver,stomach,spleen,pancreaticoduodenal complex,and part of the colon) for the treatment of otherwise unresectable tumors is one of the more radical operations in oncology.Some new surgical methods such as liver-intestinal,liver-kidney,pancreas-kidney and multivisceral cluster transplantation have emerged recently.These new advance surgical approache improve the curative effect of abdominal organ transplantation.
