Objective To analyze the etiologic factors and clinical manifestation of intraventricular hemorrhage (IVH) in preterm infants.Methods One hundred and seventy-two preterm infants from June 2005 to August 2006 were accrued to investigate their gestational age,birth weight,birth history,and clinical symptoms.Cranial chromatic ultrasound was used to scan the preterm infants and diagnose IVH.Results 1.The incidence of IVH was associated with gestational age (?2=6.40 P=0.011);2.The incidence of IVH was also associated with birth weight(?2=26.49 P=0);3.IVH usually occurred within 72 h with mild clinical manifestations and was diagnosed within 5 days after birth;4.IVH occurred more frequently and more severe in infants with severe asphyxia than those with mild asphyxia.Conclusions Early gestational age,low birth weight, and severe asphyxia are risk factors for IVH.The clinical symptoms of IVH are usually mild in most patients.Cranial chromatic ultrasound is a reliable,sensitive and convenient method of detection for IVH in preterm infants.

Objective To observe and scale knee joint space of the patients who suffered adults' Kaschin-Beck disease (KBD) in Shangzhi City of Heilongjiang Province in order to acquire basic knowledge for upcoming intervention trial. Methods Clinical test was proceeded in adults aged above 40 in Guanghui Village of Shangzhi City in 2007. In typical patients, bilateral knee X-ray was taken and knee joint space was scaled. Three points were chosen on inner and outer epicondyle of each knee and results were recorded. Results There were 307 peoples over the age of 40 in the village. Two hundred eighty-two accepted clinical test, in a rate of 91.9%. Eighty out of 282 suffered KBD, accounting for 28.4%. When the patients' condition became more serious, measurements from flank, middle, inside points on outer epicondyle of joint space presented a narrowing trend [degree Ⅰ: (5.85±0.17), (4.84±0.17), (4.36±0.18)mm; degree Ⅱ: (5.11±0.43), (4.24±0.34), (3.48±0.28)nun; degree Ⅲ: (3.59± 0.78), (3.10±0.56), (2.14±0.62)mm; Fflank,middle,inside= 6.547,5.372,10.302, all P < 0.05], but those on inner epicondyle of joint space did not[degree Ⅰ:(3.66±0.17), (3.47±0.17), (3.73±0.18)mm; degree Ⅱ:(3.55± 0.34), (3.54±0.29), (4.35±0.35)mm; degree Ⅲ: (3.19±0.72), (3.92±0.66), (4.51±0.72)ram; Finside,middle,flank= 0.351,0.356,1.883, all P > 0.05]. Joint space < 5.00 mm were found in 618, among which 363 were measured on inner epieondyle, obviously greater than those measured on outer epicondyle of joint space(255), the difference being statistically signifieant(χ2=9.59, P<0.05). Conclusions Adult cases of KBD occur in Guanghui Village. Knee joint space of adult patients narrows obviously, the more serious, the narrower, especially occurring more obviously on outer epicondyle, but frequently on inner epicondyle.

Objective To explore the changes of gastrin(GAS),motilin(MTL) and somatostation(SS) excretion in children with helicobacter pylori(Hp) related chronic gastritis.Methods The levels of GAS,MTL and SS were measured by radioimmunoassay on 50 patients in study group and 30 children in control group.The biopsy of mucosa speciments of antrum of stomach and duodenal ampulla on patients were made by fibrogastrocopy and the speciments were stained by Giemsa for histopathologic examination.Results 1.The level of serum GAS on patients with Hp-positive and Hp-negastive were(173?36) ng/L and(110?20) ng/L,respectively,t=3.274(P0.05.3.The level of serum SS on patients with Hp-positive and Hp-negastive were(144.5?11.0) ng/L and(187.4?26.0) ng/L,t=3.897 P

Objective To study whether hyperthermia and ionizing radiation could produce combined effects on the neurobehaviors of neonatal rats.Methods These rats who were pregnant for 8 or 9 days received respectively total body irradiation by 60Co-rays .When the rats were pregnant for 10 days,the temperature of rat anus was kept at (37?0.5) ℃,(41?0.5) ℃,(42?0.5) ℃,respectively in warming boxes and lasted for 2,3,4,5 minutes.The neurobehaviors of neonatal rats were observed.Results In contrast to control group and 37 ℃group ,when pregnant rats were exposed to high temperature.the neonate rats were delayed for the appearance of four physiologic markers,the age of acquisition for four reflexes and the time of learning and memory(P

To explore the new method of discriminating Cistanche deserticola, Cynomorium songaricum and Orobanche pycnostachya by using PCR amplification of specific alleles. 30 samples of the different C. deserticola, 21 samples of C. songaricum and O. pycnostachya were collected. The total DNA of the samples were extracted, the ITS sequences from C. deserticola, C. songaricum and O. pycnostachya were amplified by PCR and sequenced unidirectionally. These sequences were aligned by using ClustulW. Specific primer was designed according to the ITS sequences of specific alleles, and PCR reaction system was optimized. Additionally, compare with the identification of specific PCR method and DNA sequence analysis method. The result showed that the 331 bp identification band for C. deserticola and the adulterants not amplified bands by a single PCR reaction, which showed good identification ability to the three species. PCR amplification of specific alleles can be used to identify C. deserticola, C. songaricum and O. pycnostachya successfully.
