Objective To select the acceptor ingredients of Streptococcus mutans protein in the whole saliva through the interaction between adhesion and saliva protein of Streptococcus mutans. Methods After activation and liquid culture of Streptococcus mutans strains of international standards, we took Su-bonding from liquid culture of bacteria secretion in the process of liquid culture by using chilled ethanol extraction. Then su-bonded components underwent electrophoresis analysis, content determination and antigen detection. We collected 15 with high carries and 15 with no carries. Two hours after eating, the whole non-irritating saliva was collected, electrophoresis samples were prepared after freeze-drying, and then stains were separated with SDSPAGE. Western blot detection was used for adhesive protein and Streptococcus mutans' antibody composition. Results The ingredients of Su-bonding secreted on the surface of Streptococcus mutans were obtained in the cultured saliva. There were at least six kinds of components in the extraction of Western blot detection, not limited to the three known kinds of proline-rich protein. Conclusion The adhesion of Streptococcus mutants can be bound with the proteins of saliva. It may be the material basis in Streptococcus mutants adhered to tooth surface.

Objective To investigate the effect of desflurane on neuromuscular blockade of rocuronium Methods Thirty adult patients ,scheduled for selective surgery under general anesthesia, were randomly allocated to receiving intravenous propofol 4mg?mg -1 (group I,n=10),inhalation of 1MAC(6%) desflurane lasting 15 min (group Ⅱ,n=10) or 45 min(group Ⅲ,n=10) to maintain anesthesia,respectively Rocuronium 0 6 mg?kg -1 was given intravenously in group I following stable anesthesia , in group Ⅱ or group Ⅲ with the stable end tidal concentration of desflurane at 1MAC for 15 min or 45 min,respectively The onset time and degree of neuromuscular blockade were monitored with train of four(TOF) technique.Results The onset times of T 1 and TOF in group Ⅲ(1 3 and 0 8 min) were shorter than in group I(2 2 and 1 5 min)(P

Objective By investigating the quality and unreasonable prescription of traditional Chinese medicine in our hospital, to analyze the reason and thus put forward the solution and elevate the whole rational administration level in our hospital. Methods 3000 prescriptions prescribed in our hospital from April 2008 to April 2009 were randomly investigated. Select the unreasonable prescriptions and unreasonable use of medicines in a prescription for statistical analysis. Results There were 258 unreasonable prescriptions among spot-check 3000 sheets of prescriptions, reaching 8.6%. There were 633 unreasonable medications, including oversized or excessively small dosage, improper compatibility, repeated medications, etc. Conclusion There is the phenomena of unreasonable prescription in our hospital. Therefore, we should reinforce the management of prescribing medicines and enhance the level of reasonable medication.

In the present study the projections were traced from the red nucleus and the region of the griseum centrale mesencephali to the inferior olivary complex (IOC) by using the method of anterograde transport of the WGA-HRP in the cat. The results has led to the following conclusions: 1.Both injected regions have positive projections to the ipsilateral IOC. No labeled cells were found in the IOC. 2. The projections from the red nucleus to the IOC terminated in the dorsal lamina of the principal olive and the dorsal end of the caudal half of the medial accessory olive. The projections from the region of the griseum centrale mesencephali to the IOC terminated in the whole medial accessory olive, ventral lamina of the principal olive and the connecting part between the ventrolateral end of ventral lamina and dorsal lamina of the principal olive. The most heavily labeled regions were the dorsal lamina of the principal olive among the regions receiving projection from the red nucleus and the medial accessory olive among those receiving fibers from the griseum centrale mesencephali region, the other regions were more lightly labeled.3. Some labeled regions of the IOC in the present study overlapped with those regions receiving fibers from the spinal cord reported by others. In the present study the labeled area is more extensive than those reported in the literature.

Objective To evaluate the short-term effect of pelvic floor muscle rehabilitation training under the guidance of doctors on children with neuropathic acontractile sphincter incontinence ( NASI ).Methods Sixty eighty children[aged 4 - 12 ( mean, 7 ) years]with NASI were selected.All children were randomly divided into multiple guidance group and single guidance group.Pelvic floor muscle rrehabilitation training was successfully accomplished in all children.Three-day urinary diary, 7-day fecal diary, the ICI-Q-SF score and urodynamic evaluations were completed before and after the treatment.Three months later, follow-up was carried out.The results were compared between the groups.Results After treatment,TOV, LT, TFI and ICI-Q-SF of multiple guidance group were significantly lower than those of single guidance group[(29±8) vs (34±12), (19±10) vs (25 ±12), (1.9±1.1) vs (2.5 ±1.3), (9±5) vs ( 12 ± 6 ), P ＜ 0.05], however, PMUC of multiple guidance group was significantly higher than those of single guidance group[(5.6 ± 2.0 ) vs (4.7 ± 1.7 ), P ＜ 0.05].The effective rate of multiple guidance group after treatment and at follow-up were respectively 79.4% and 70.6% , significantly higher than those of single guidance group ( 64.7% and 50.0%, P ＜ 0.05 ).Conclusion Pelvic floor muscle rehabilitation training under the guidance of doctors has satisfactory therapeutic efficacy on the children with NASI.

Objective To observe the histomorphological changes of sciatic nerves following pasteurizing warm temperature treatment. Methods The 12 mm left sciatic nerve from healthy adult male Wistar rats was pasteurized at 60℃ for 30 minutes and observed at the first week (1-week group) and the sixth week (6-week group), 15 rats per group. Number, diameter and area ratio of the myelinated axons in the control (proximal to the treated part), treatment and peripheral nerves (distal to the treated part) were calculated. The histomorphological changes were examined with electrophysiological and electron microscopies. Results (1) In the peripheral part, the number of the myelinated axons was significantly decreased in the 1-week group compared with the control group (P

Objective To explore diagnosis and treatment of thoracolumbar spine and spinal cord trauma complicated by thoracoabdominal viscera injury. Methods A retrospective study was performed on 84 cases with thoracolumbar spine and spinal cord trauma complicated by thoracoabdominal viscera injuries treated in our unit from January 1986 to December 2002, of which there were 52 cases with thoracic vertebra fracture (T_6-T_(12)), 32 with lumbar fracture (L_1-L_4), 70 with complicated chest injury, 14 with abdominal injury and 34 with injuries of cranium, extremities and pelvis. Spinal fixation or decompression of spinal cord was performed in 62 cases, drainage in 22, laparotomy in 10 and exploration of skull in nine. Results Eighty-two cases survived, with follow up period for 6-36 months. According to Frankel standard nerve function recovery showed that among 36 cases at grade A, 10 had partial or sensation recovery and the other got nerve function improvement for gradeⅠ-Ⅲ. Delayed diagnosis and missed injuries totaled seven cases (12%). Two cases were died of postoperative MODS. Conclusions As for patients with thoracolumbar spine and spinal cord trauma complicated by thoracoabdominal viscera injury, a comprehensive clinical examination including X-ray or CT is necessary. The treatment should first focus on thoracoabdominal viscera trauma and try to avoid aggravation of spine and spinal cord injury.
