OBJECTIVE:To study the preventive effects of arhinhor-11 on acute alcoholism in mice. METHODS:48 mice were randomly divided into model group (sodium carboxymethyl cellulose),arhinhor-11 low-dose,medium-dose and high-dose groups [1.23,2.46,4.92 g(crude drug)/kg],with 12 mice in each group. Each group was given relevant medicine intragastrically, and 30 min later given 56% liquor intragastrically to induce acute alcoholism model. The disappearance time and recovery time of righting reflex were determined. 160 mice were grouped,given medicine and modeled with the same method,with 40 mice in each group. The alcohol concentration and alcohol dehydrogenase(ADH)activity in liver of 10 mice were determined 0.5,1,2,3 h af-ter giving alcohol. Other 10 mice were included in normal control (ig administration of sodium carboxymethyl cellulose). RE-SULTS:Compared with model group,the disappearance time of righting reflex were prolonged while recovery time shortened in arhinhor-11 groups,and alcohol concentration and ADH activity increased 0.5,1,2,3 h after giving alcohol (P<0.05 or P<0.01),especially 1 h after giving alcohol. 3 h after giving alcohol,alcohol concentration in blood of arhinhor-11 high-dose group decreased while ADH activity increased (P<0.05);there was no statistical significance among other arhinhor-11 groups (P>0.05). CONCLUSIONS:Arhinhor-11 has preventive effect on acute alcoholism in mice. It has a positive control effects on the alco-hol concentration in blood and ADH activity in liver.

Objective To investigate the relationship between single nucleotide polymorphisms of surfactant protein C(SP-C)gene and respiratory distress syndrome(RDS)in the Han nationality newborns in Inner Mongolia and whether there is a mutation occurs on SP-C gene exon 4 and 5.Methods One hundred newborns with RDS(case group)and 100 newborns without RDS(control group)were selected.PCR gene analysis was used to establish the genotype and allele frequencies of exon 4 (T138N)and 5 (S186N)on SP-C.Results In the Han nationality newborns of Inner Mongolia region,there was no mutation on SP-C gene exon 4 and 5.Exon 4(T138N)on SP-C could be checked out three genotypes:namely AA,AC and CC.The genetic polymorphisms of exon 4 on SP-C were not statistically different between the case group and the control group(χ2 ﹦0.744,P ﹦0.689).Besides,exon 5(S186N)on SP-C could also be checked out three genotypes:namely AA,AG and GG.The genetic polymorphisms of exon 5 on SP-C were also not statistically different between the case group and the control group(χ2 ﹦0.770,P ﹦0.681 ).Conclusion There is no mutation on SP-C gene exon 4 and 5.The genetic polymorphism of exon 4 and 5 on SP-C displays no signifi-cant correlation with RDS of the Han nationality newborns in Inner Mongolia.

Bilateral lung lavage was performed under general anesthesia with muscle relaxation in 3 patients with pulmonary alveolar proteinosis(PAP)aged 43-57 yrs weighing 48-68 kg.Left lung lavage was performed first and the right lung was lavaged one week later.Left radial artery and right internal jugular vein were cannulated for MAP,HR and CVP monitoring.SpO_2 and P_(ET) CO_2 were monitored during lavage.Left-sided Robertshaw double-lumen tube was used for both right and left lung lavage.After proper placement of the double- lumen tube was verified both lungs were ventilated with 100% O_2 for 10 min to wash out N_2.Hyperoxygenated lavage fluid was made by aerating the lactated Ringer's solution with 100% O_2 at 1 L?min~(-1) flow rate for 30 seconds.The tidal aliquot of lavage was 700 ml which was kept in the lung for 50 seconds and then drained.Each lung was lavaged with hyperoxygenated and plain lactated Ringer's solution 10 times each alternatively.While one lung was being lavaged the contralateral lung was mechanically ventilated with 100% O_2.SpO_2,MAP,HR,CVP and P_(ET)CO_2 were recorded immediately before lavage and at 10,20,30,40,50,60,70 and 80 seconds after the lung was filled with lavage fluid.SpO_2 was significantly higher during lavage with hyperoxygenated fluid than with ordinary lactated Ringer's solution,but there was no significant difference in MAP,HR,CVP and P_(ET)CO_2.The PaO_2 of the 3 patients breathing room air was 46-52 mm Hg before lung lavage and increased to(72.3?2.1) mm Hg one week after left lung lavage and to(83.5?4.8)mm Hg 3d after right lung lavage.During the lung lavage,hyperoxygenic significantly improve oxygen supply in patients with pulmonary alveolar proteinosis compared with lactated Ringer's solution.

To describe a modified simple iris suture for pupillary dilation technique during vitrectomy in cases with a miotic pupil.Four translimbal incisions were created with a sharp straight blade at 1:30,10:30,4:30,and 7:30 o'clock,respectively.The straight needle of 10-0 polypropylene suture and a Sinskey IOL hook was used to displace the pupillary margin toward the limbus.In 3 cases,four sutures caused a 6-mm to 9-mm square-shaped pupil,and the pupil was allowed to return to a smaller size at the end of the operation.It is simple and may reduce postoperative complications.

Objective To study the perioperative nursing methods in patients with OSAHS and type 2 diabetes mellitus.Methods From March 2009 to December 2010,a total of 46 patients with OSAHS and type 2 diabetes mellitus were randomly divided into the control group and the experimental group with 23 cases in each group.Conventional care was given to the control group,while the experimental group received systematic,phased and individualized nursing.The sleep quality before and after the operation was compared.The oropharynx wound healing and possible complications,pain were observed after operation.Results In the control group,there was one patient with bleeding during operation,one patient happened blood lost after operation and 2 patients had postoperative infection.The hyperglycemia was found in 3 patients and hypoglycemia occurred in 2 patients.But in the experimental group,all of the patients did not suffer complication.The scores of sleep quality on the day before surgery were significantly higher than those scores on admission,and the scores on discharge from hospital were significantly lower than those scores on admission.There were statistical differences.The scores of the experimental group were significantly improved compared to those of the control group.The score of pain was the highest at the day of surgery,and then gradually decreased.The score of pain of the experimental group was significantly lower than that of the control group,and the difference was statistically significant.Conclusions This comprehensive nursing method during operation period for patients with OSAHS and type 2 diabetes mellitus not only can reduce risk of postoperative complication,but also can improve operation efficacy,quality of nursing and life quality of patients as well as can speed recovery.It approved that this standardized,systematic nursing method during the whole period is practical and effective in OSAHS and type 2 diabetes mellitus treatment and care.

Objective To investigate the effects of bilateral sternocleidomastoideus contraction on neck flexion and extension. Methods The electromyograms (EMG) signals of left sternocleidomastoideus of 24 healthy persons were recorded respectively when neck relaxation and flexion in the supine position, and neck relaxation and extension in the prone position. The biomechanical measurement and analysis were done using anatomical specimens and models. Results The sternocleidomastoideus registered electrical resting potential when neck relaxation in the supine position, and when neck relaxation and extension in the prone position; the motor unit action potential of sternocleidomastoideus raised the type of mixed phase when neck flexion in the supine position. Conclusion The contractions of bilateral sternocleidomastoideus can lead to the head and neck flexion while neck joints are not fixed, and the contractions of bilateral sternocleidomastoideus can lead to the head extension under the state of fixing neck joints below atlanto-occipital.
