1.The disorder of ejaculation in the treatment of the male infertility
Journal of Practical Medicine 2002;435(11):16-18
Ejaculatory incompentence is not able to ejaculate intravaginally. Psychological causes are generally associated with an inability to ejaculate intravaginally. The treatment of ejaculatory incompetence is very difficult and complicated. The treatment of retrograde ejaculation is much more difficult. Such patients have a very low volume ejaculate but numerous sperm can be found in the urine and on physical examination, testicles are of normal size. Sperm recovery from the urine could be used for AIH. The treatment for some men with paraplegia who do not ejaculate with a vibrator. We can perform the whole process of ejaculation in electro- ejaculation

Background: Acute Respiratory Infection (ARI) is a common disease in developing countries. Morbidity and mortality of ARI are high, especially among children under 15 years old. Objectives: To describe socio-graphic factors, seasonal patterns, risky areas and determine the morbidity and mortality rates of acute respiratory infections in Thai Binh province. Subjects and method: This retrospective study reviewed the medical records of 4,585 hospital admitted patients who were diagnosed with ARI including upper and lower respiratory infections such as sore throat, pharyngitis, bronchitis, pneumonia and bronchitis-pneumonia at 8 district hospitals and 1 provincial hospital in Thai Binh province during 2002-2005. The selected medical records were based on the available check list and two standard screening tests. Results:Morbidity and mortality of ARI in Thai Binh province were 61.6 and 0.52, respectively. ARI mainly occurred among children under 5 years old, of which the highest mortality was among those under 12 months of age. Male children were at higher risk of acquiring ARI, but less prone to death than female. Occupation did not significantly associate with the risk of ARI. The morbidity increased sharply during inter-season, e.g. March and October. Thai Binh city, Kien Xuong and Tien Hai district were reported with the highest morbidity in accompany of the high mortality as consequences. Conclusion: The prevention and control methods were recommended to annually focus on the male children aged less than 5 years old during March and October in Thai Binh city, Kien Xuong and Tien Hai district.

Background: Child health care practices in the context of households and community is an important factor to improving the health of children. Some indexes were proposed by the World Health Organization to evaluate these practices. Objectives: To describe the knowledge and practice of pregnant women, under-5-year-old children\u2019s health care and assess the application of the survey toolkit in evaluating various indexes of healthcare practice at family and community levels. Subjects and method: By employing a structured interview, this cross-sectional survey has been conducted in Tu Liem district - Hanoi city and Tien Hai district \u2013 Thai Binh province. 120 mothers of under-5-year-old children participated in the survey. Results:98% of mothers had at least 3 antenatal visits during pregnancy. The rate of complete tetanus vaccination reached 43.3% in Tu Liem and 65% in Tien Hai. Prevalence of infant with low birth weight for age accounted for 8.3% in both districts. The percentage of children given complementary feeding at age of 6 to 9 months as the National Nutrition Program recommendations was only 30%. 65.7% and 68.5% of under-2-year-old children in Tu Liem and Tien Hai were breastfed within the first 30 minutes after delivery. There were a small proportion of mothers who gave complementary food either too early or too late, 8.3% and 8.4% in Tu Liem, 6.7% and 6.6% in Tien Hai, respectively. More than 90% of children were given normal feeding as usual during last their illness, but only 50% of children were given more fluid than usual. 98.2% of mothers knew 2 signs to immediately bring the child to health facilities. The most common injuries in under-5-year-old children were animal bites (62.5%) and falling (31.3%), however only 62.5% of mothers knew at least two measures of injury prevention. Conclusion: The toolkit for collecting data of practical index assessment can be applied at communes.

Ultrasonic computed tomography based on back scattering theory is the most powerful and accurate tool in ultrasound based imaging approaches because it is capable of providing quantitative information about the imaged target and detects very small targets. The duple-frequency distorted Born iterative method (DF–DBIM), which uses density information along with sound contrast for imaging, is a promising approach for imaging targets at the level of biological tissues. With two frequencies f₁ (low) and f₂ (high) through Nf₁ and Nf₂ iterations respectively, this method is used to estimate target density along with sound contrast. The implications of duple-frequency fusion for the image reconstruction quality of density information along with sound contrast based ultrasound tomography have been analyzed in this paper. In this paper, we concentrate on the selection of parameters that is supposed to be the best to improve the reconstruction quality of ultrasound tomography. When there are restraints imposed on simulated scenarios to have control of the computational cost, the iteration number Nf₁ is determined resulting in giving the best performance. The DF–DBIM is only effective if there are a moderate number of iterations, transmitters and receivers. In case that the number of transducers is either too large or too small, a result of reconstruction which is better than that of the single frequency approach is not produced by the implementation of DF–DBIM. A fixed sum N(iter) of Nf₁ and Nf₂ was given, the investigation of simulation results shows that the best value of Nf₁ is [N(iter)/2 − 1]. The error, when applying this way of choosing the parameters, will be normalized with the reduction of 56.11%, compared to use single frequency as used in the conventional DBIM method. The target density along with sound contrast is used to image targets in this paper. It is a fact that low-frequency offers fine convergence, and high-frequency offers fine spatial resolution. Wherefore, this technique can effectively expand DBIM's applicability to the problem of biological tissue reconstruction. Thanks to the usage of empirical data, this work will be further developed prior to its application in reality.
