There are 22.94% HBsAg(+) and 41.28% anti-HBs(+) in pregnant women in Dalat. The risk of transmission of the virus is especially high (63.64%) in newborns of carrier mothers who have tested positive for both HBsAg and HBeAg. Beside 8% of newborns have been infected with HBV from horizontal transmission.

174 healthy newborn babies in Lam Dong General Hospital, body weight > 2.500g without congenital abnormality, whose mother did not immunized previously with B hepatitis vaccine, were received an infection of HB vaccine of 10mg initially 24-48 hours after birth. After 3 injections of GMT anti HBS of 650.02 mIU/ml, the antibody response was 95.43% with a GMT of 1041.21 mIU/ml. The antibody response in fully immunized was 98.38%

Objective: To determine the 16S rDNA sequences of 44 strains of Sulfitobacter sp. obtained from the East China Sea and to study their biological activities. Methods: PCR was used to amplify the 16S rDNA sequences of the 44 strains, and the obtained sequences were subjected to GenBank similarity search. The multiple sequence alignment of the 44 strains was done by Clustal Xl. 8 and MEGA4. 1. The antibacterial activities of Sulfitobacter sp. fermentation broths were tested using the following indicator bacteria: Pyricularia oryzae, Bacillus subtills, and Escherichia coli. The cytotoxic activities of the fermentation broths were tested using HL-60 and HepG2 as the indicator cells. ABTS and DPPH antioxidant models were applied to test the free radical scavenging efficacy of the fermentation broth. Results: Analysis of the 16S rDNA genes of the 44 strains showed high similarity (97%-100%) to Sulfitobacter sp.. No fermentation broths of the 44 strains showed evident anti-bacterial activities, and they showed different degrees of cytotoxic activities and free radical scavenging capacities. Nineteen strains inhibited the growth of HepG2 cells, with the inhibition rate ranging 6.8%-42.8%; 18 strains inhibited the growth of HL-60 cells, with the inhibition rate ranging 6.9%-43.6%; 12 strains showed ABTS radical scavenging capacity, with the elimination rate ranging 4.49%-23.08%; and 8 strains showed DPPH radical scavenging capacity, with the elimination rate ranging 1.23%-30.76%. Conclusion: The 44 Sulfitobacter sp. strains possess evident cytotoxic activities and free radical scavenging capacities, making them potential for medicinal application and laying a foundation for further development of these bacteria.

The paper introduces the development of hematology analysis technique in recent 10 years,and mainly concentrates in WBC differential technique,the extended functions and automation.The clinical application of red cell volume distribution width,reticulated platelets and reticulocyte subpopulation are also described in the paper.The common problems in the usage of hematology analyzer and correction methods are pointed out.

The Halliwick concept is a kind of aquatic kinesitherapy concept to reduce disability and improve quality of life through activities in water such as swimming. It mainly includes the Halliwick Ten-Point-Programme aimming at teaching siwmming and the Water Specific Therapy focusing on impairments of body functions or body structure. The Halliwick concept can be relatead to the International Classification of Functioning, Disability and Health very well, and its therapeutic effects has been supported by more and more evidence-based-studies.

Underwater treadmill training (UWTT) is a new hydrotherapy technique, with features of immersion bath, under water walking and body-weight support treadmill training. UWTT can reduce the load on legs, release spasm, improve gait, muscle atrophy and remain muscle strengthen for SCI patients. It also reduces the risk for cardiovascular disease, and incidence of postural hypotension. The present studies on UWTT are insufficient. More researches should further explore the therapeutic effects on SCI.

Inquisition language,as the information carrier on observing and describing disease status,makes it possible for patients to communicate well with doctors to acknowledge disease information.In order to make inquisition language possess specific properties of medical conversation,doctors need to master language skills in procedural inquisition,proper listening and responding to inquisition,distinguishing inquisition,transitional inquisition and secret-involved inquisition.Upholding inquisition language with courtesy,comfort,being explanatory,encouraging,and protecting is the basic requirement of clinical ethics.

Objective To study the effects of Pervanadate(Per) on BET-2 cells cell cycle arrest and apoptosis induced by ionizing radiation. Methods The BET-2 cells were radiated with 0, 1, 3, 5, 7, 10 Gy and divided into PTP(protein tyrosine phosphatases)-specific inhibitor Per-treated group and non-pervanadate group(served as a control) and then incubated after ?-ray irradiation. Cell cycle and apoptosis were measured by FCM and Hematoxylin-Eosin staining at different time phases. Results G2/M phase arrest and apoptosis were induced in a pattern of dose-effect and time-course after irradiation in the BET-2 cells. In Per-treated group, G2/M phase arrest increased more notably, and apoptosis decreased markedly. Conclusions These studies suggested that Pervanadate potentialy enhance the ratio and prolong the term of G2/M phase arrest, and facilitate the damaged hematopoietic cells to be repaired, remarkably prevent radiated-cells from apoptosis.

Objective: To observe the influence of left-thoracic radiotherapy on heart function and quality of life in patients with breast cancer after breast-conserving surgery. Methods: A total of 35 patients with breast cancer, who recently received breast-conserving surgery and left-thoracic radiotherapy, were continuously selected as radiotherapy group. They received routine echocardiography (ECG), tissue Doppler imaging (TDI) and evaluation of Chinese questionnaire of quality of life in patients with cardiovascular diseases (CQQC) before and after radiotherapy. The results were compared with those of 31 patients (control group), who received radical mastectomy without breast radiotherapy in the same period. Results: There were no significant difference in left heart function indexes by ECG and TDI, all dimensional and total scores of CQQC between two groups before radiotherapy (P>0.05 all). After five-week treatment, compared with evaluation before radiotherapy and control group after treatment, there were significant decrease in E [(0.90±0.32) cm/s vs. (0.90±0.38) cm/s vs. (0.86±0.29) cm/s], E/A [(1.28±0.46) vs. (1.28±0.45) vs. (1.20±0.38)], Em [(10.12±1.93) cm/s vs. (9.95±1.64) cm/s vs. (7.51±1.12) cm/s], Em/Am [(1.25±0.26) vs. (1.24±0.23) vs. (0.90±0.15)] （P<0.05 all）, all dimensional scores （P<0.05～<0.01）and total score [(67.36±7.87) scores vs. (63.75±7.26) scores vs. (52.83±6.40) scores] （P<0.01）of CQQC in radiotherapy group. Conclusion: There are often decrease in left heart function and quality of life in patients with breast cancer undergoing left-thoracic radiotherapy after breast-conserving surgery, so it’s necessary to perform targeted rehabilitative treatment.
