AIM: To investigate the postoperative changes of binocular visual function in patients with congenital superior oblique palsy.METHODS: Eye position and binocular visual function were examined in 28 patients with congenital superior oblique palsy pre- and post-operatively. The results were statistically analyzed.RESULTS: The normal eye position rate after operation was 89.3%. There were 9 patients who gained simultaneous perception after operation, while 13 patients gained fusion as many as that gained stereoacuity. There was statistically significant difference between postoperative and preoperative eyes (P<0.05). Near stereoacuity was improved after operation. Patients who had better visual acuity and low strabismus degrees as well as fusion had a better recovery.CONCLUSION: The operation could improve the eye position and rebuild the binocular visual function of the congenital superior oblique palsy. The recovery of binocular visual function was related to visual acuity and strabismus degrees of the patients and whether they had fusion function.

BACKGROUND: Herbal wines are an important part of the traditional Chinese medicine. The traditional medicated wine, lishizhen herbal wine,which can strengthen the immune function, has long been used for some chronic diseases. But,its mechanism remains unclear.OBJECTIVE: To explore the immune pharmacodynamics of lishizhen herbal wine and to observe its effect on the immune organs (spleen,pancreas) and lymphocyte transformation rate in mice.DESIGN: A randomized controlled experiment based on the observation of the experimental animals.SETTING: Department of integrated traditional Chinese and western medicine and the department of pharmacology of a university hospital MATERIALS: The experiment was completed at the Central Laboratory of Zhongnain Hospital of Wuhan University from September 2000 to December 2000. A total of 90 healthy Kuming mice were involved in the study.METHODS: Different doses of the herbal wine,cartinellin and the same volume of distilled water were given to the experimental animals. The drug administration was orally injected directly to the stomach of the animals once a day and 10 days consecutively. One hour after the last administration,the animals were put to death. Then,the thymus gland and the spleen were taken out and weighed to calculate the indexes of the thymus gland and the spleen. In the last three days of the administration phytohemagglutinin(PHA)was injected intramuscularly at a dose of 10 mg/kg once per day. Two hours after the last administration, the tails of the mice were cut out, the blood samples were taken to perform the Wright' s staining,and 100 lymphocytes were counted under immersion and the transformation rate was calculated.MAIN OUTCOME MEASURES: Primary results: ① The effect on the immune organs of normal mice; ② The effect of PHA on stimulating the lymphocyte transformation in mice. Secondary results: ③ The death condition of the experimental animalsRESULTS: Different doses of the herbal wine increased the spleen index in different degrees. The effect of medium dose group was obvious[(3.71± 0.78) g/kg] (P <0.05),and the thymus gland index increased a little (P>0.05). The cartinellin in the positive control group increased the spleen index[(3.79±0.91 ) g/kg] and there was no impact on thymus gland index. The transformation rates of the lymphocytes of different groups were increased to a different degree and presented a good quantity-effect relationship,especially the group administered a large dose[(45±14)%] (P<0. 01).CONCLUSION: Lishizhen herbal wine has an effect of increasing cellular immune function.

Objective To explore the imaging characteristics of neurologic complications associated with the enterovirus 71 ( EV71 ) epidemic by analyzing 25 cases and reviewing the literature. Methods Twenty-five cases of hand-foot-mouth disease with neurologic complications during the recent EV71 outbreaks of Hainan province were studied for the clinical features and imaging findings, and literature were reviewed.Results In 5 cases, acute flaccid paralysis associated with EV71-infected hand-foot-mouth disease was related to the linear high signal in the spinal cord on sagittal images. Two cases showed symmetrical, welldefined hyperintense lesions in the spinal cord on T2WI transverse. Strong enhancement of the ventral horns and root was seen on the contrast-enhanced axial T1WI. In brainstem encephalitis, all lesions presented with significant hyperintensity on T2WI and hypointense on T1WI in the posterior portions of the medulla oblongata, midbrain, and pons. The manifestations of aseptic meningitis (AM) on MRI have no characteristics, but subdural effusion, meningeal enhancement and hydrocephalus can be the indirect signs of AM. Conclusions MRI is an effective method to investigate neurologic complications associated with the EV71 epidemic. Posterior portions of the medulla oblongata and pons, bilateral ventral horns of spinal involvement are characteristic findings of enteroviral encephalomyelitis.
