The record of speech-language abnormalities scattered in some chapters of two classics of traditional Chinese medicine, Huang Di Nei Jing and Zhong Zang Jing. The descriptive modes of these abnormalities in Huang Di Nei Jing were more diversified than in Zhong Zang Jing. In aspect of clinical values, speech-language abnormalities in Huang Di Nei Jing were used to guide clinical diagnosis and treatment, such as describing body constitution and clinical mistreatments, but rare in Zhong Zang Jing.

From 1970 to 1984,100 patients with esophageal cancer survived over 10 years after radiotherapy alone. In theis group 58 male, 42 female; section of upper thoracic 53, section of middle thoracic 47; medullary type 82, fungoid type 14; tumor length ≤5cm 49, 5.1～7.0cm 34, 7.1～9.0cm 17. They were teated by three or four intersecting radiation, total doses were 50～70Gy. 9 patients received second radiotherapy for local relapse. In 100 patients, 58 patients still survived , 42 patients died of local relapse 18, bleeding 6 and fistula 4. 5 patients suffered from radiation myelitis and 3 patients fracture of rib in 58 living patients. Conclusion: the result of treatment is better in group of young people. Patients with supraclavicular metastasis have received seccond radiotherapy after first raditherapy could still survive for a long time. Local relapse is the important factor for death yet. We think total dose is adapted between 50～70Gy. The spinal received dose

Objective To explore the role of intracranial electrode EEG monitoring for localizing epileptogenic zone in epilepsy.Methods 20 patients with refractory temporal lobe epilepsy,whose seizure onsets were unable to be localized by MRI、routine EEG and clinical characteristic,accepted long-term intracranial electrode EEG monitoring.Bitemporal lobe subdural implanted trip electrode were used to perform the ictal and interictal EEG monitoring under the guiding of the stereotactic technique.The results routine of EEG,MRI and intracranial electrode EEG were combined.The accuracy for localization of epilepitogenic zone was evaluated based on the followed-up.Results The intracranial electrode EEG monitoring was implanted within 1～5 d.Each patient was recorded the ictal and interictal discharge and was detected clinical onsets at least twice.All patients could be localized by ictal EEG.The consistency between interical EEG and ictal EEG were observated in 15 cases,the inconsistency in 3 cases,and 2 cases were bilateral discharge in interictal.The clinical outcome showed that patients were seizure-free in 13 cases(65%),improved significantly in 3 cases(15%),improved in 3 cases(15%),unimproved in 1 case(5%)according to Engel's criteria after surgery.No significant complication was found in all patients.Conclusion The intracranial electrode EEG monitoring can localize epileptogenic zone and offer reliable evidence for epilepsy surgery.

Objective To observe the improvement effects of astragaloside Ⅳ (AS-Ⅳ)on the myocardial focal ischemia-reperfusion (I/R)injury and its influence in PI3K/Akt/mTOR pathway,and to clarify the protective effect of AS-Ⅳ on myocardial I/R inj ury and the possible mechanisms.Methods The left main coronary arteries of 60 Sprague-Dawley rats were occluded for 30 min followed by a 120-min reperfusion to induce I/R model.The rats with I/R inj ury were randomly divided into model group (normal saline), AS-Ⅳ group (intravenous inj ection of 10 mg·kg-1 AS-Ⅳ 5 min before reperfusion),PI3K inhibitor Wortmannin (WOR)group (intravenous injection of 0.6 mg·kg-1 WOR 10 min before reperfusion)and AS-Ⅳ+WOR group (intravenous injection of 10 mg·kg-1 AS-Ⅳ and 0.6 mg·kg-1 WOR 5 and 10 min before reperfusion,respectively).15 age-matched SD rats were chosen as control group.The heart mass,degrees of infarction and ischemia and cardiac function ,including left ventricular systolic mean pressure (LVSP),end-diastolic pressure (LVEDP),fractional shortening (FS)and ej ection fraction (EF),of the rats in all groups were analyzed. Western blotting method was used to measure the phosphorylation levels of Akt and mTOR(p-Akt and p-mTOR).The specific fluorescent probe DHE staining was employed to detect the myocardial reactive oxygen species levels. Results Compared with control group, the degrees of infarction and ischemia, LVEDP, myocardial levels of p-Akt/Akt, p-mTOR/mTOR and reactive oxygen species levels of the rats were increased (P<0.05).and the levels of LVSP,FS and EF were decreased in model group (P<0.05). Compared with the model group,the degrees of infarction and ischemia,LVEDP and reactive oxygen species level were decreased (P<0.05),while the levels of p-Akt/Akt,p-mTOR/mTOR LVSP, FS and EF of all rats in AS-Ⅳ group were increased (P<0.05).Compared with AS-Ⅳ group,the degrees of infarction and ischemia,LVEDP and reactive oxygen species levels of the rats in WOR group and AS-Ⅳ+WOR group were increased (P<0.05 ), and the myocardial p-Akt/Akt, p-mTOR/mTOR and LVSP, FS, EF were decreased (P<0.05).Conclusion AS-Ⅳ has improvement effect on myocardial I/R injury.AS-Ⅳ can reduce the extent of myocardial infarction and oxidative stress and improve the heart function,and its possible mechanism may be related to activating PI3K/Akt/mTOR signaling pathway.
