- 摘要：Recently it was supposed by many researchers that posterior group of nuclei in thalamus(PO)took important role in reception of pain sensation. However,there were some controversy among researchers over topograghy, classification and function of the subnuclei in PO. In this reriew,topography of the PO,the connection of PO with somatic and visceral afferent nerve fibers,the connection of PO with cortex,especially the secondary sensory area and the characteristics of noxious neurons in PO were summarized. All in all,PO in thalamus was referred to as important integrative cen- ter of pain sensation.779|0|0更新时间：2023-08-11
- 摘要：118 patients receiving herniorrhaphy under electroacupuncture anesthesia were divided into two groups.Their adjunct acupoints were different.According to the grading crireria of the effectiveness of this method,the rate of success in these two groups was 94.2% and 83.9% respectively.the analgesic effect was better in the first group.Indications,supplementary medications, methods of acupoint selection and needle manipulation,supervision of anesthesia,techniques of surgical operation,relations between effectiveness and age, effectiveness and operative duration,and the influence of herniorrhaphy under electro-acupuncture anesthesia on the blood pressure and pulse rate of the patients were studied and summarized systematically. Results demonstrated that this method of anesthesia is applicable as a routine to herniorrhaphy of indirect inguinal hernia,direct hernia,communicating hydrops of funicular tunica vaginalis,and femoral hernia,etc.It is espe- cially applicable to the surgical manoeuvre of the femoral hernia blood press- ures were stable in most patients with hypertension,while some fluctuations of different degrees occurred in a few of them.But no adverse reactions developed.Electro-acupuncture anesthesia for herniorrhaphy is safe and trustwor- thy;patients recovered their health more rapidly.In addition to these advanta- ges,no complications occurred after anesthesia and no special nursing care was needed.It is a new method of anesthesia welcomed by surgeons,nurses, and palients.721|0|0更新时间：2023-08-11

- 摘要：Dicaine 34μl/100 body weight).The ane- sthetic range was maintained within T_(4-11) used in subtotal gastrectomy.Under this condition,the messages of acupuncture at“Zusanli”acupoint transmi- tting the somatic sensory pathways in spinal cord was not significantly influ- enced by the drugs and went up to the higher part of the brain to perform the inhibitory effects on stomach traction reactions. The mechanisms of the effeciency and the advantages of conbined acupu- ncture anesthesia with a minimum dose of epidural block were schematically ndisussed.881|0|0更新时间：2023-08-11
- 摘要：Experiments were performed on cats under chloralose and flaxedil。 The splanchnic nerve was stimulated with electric pulses of various intensities and blocked by a polarizing current so as to excite different kinds of fibers(Aβ,Aδ,C)。The averaged evoked potentials were recorded in the contralateral somatosensory cortex(CEP). Aβ-CEP evoked by Aβ fiber input showed a primary positive wave; Aβδ-CEP elicited by Aβ and Aδ fiber inputs showed a primary response and a secondary response,late component;Aε-CEP by Aδ fiber input showed a secondary and late response.These results indicated that the primary response of A-CEP was evoked by Aβ fiber input,and the secondary and late response by Aδ fiber.AC-CEP by A-and C-fiber inputsappeared similar to Aβδ-CEP.It was suggested that C fiber input might be inhibited by A fiber input and did not participate in AC-CEP. After blocking the A fiber by a polarizing current,a stimulus above C fiber threshold would cause a particular C-CEP,and the amplitude depended on the amount of afferent C volley. From the above results we tend to believe that all of the fiber inputs (Aβ,Aδ,C)may reach the somatosenory cortex and elicit CEP,and that C-CEP reflecting C fiber input accurately may be a suitable index for visceral pain,and AC-CEP only reflects the A fiber input but not the C fiber.724|0|0更新时间：2023-08-11
- 摘要：Somatosensory evoked potentials(SEPs)were recorded simultaneously from the cervical spine and scalp in 10 normal subjects and 22 patients with cerebrovascular attack(9)and syringomelia(13)using median nerve stimulation.Patients were considered as having abnormal studies,if either N_(18) were absent or if their peak latencies were prolonged more than 21.1 msec,or if the difference of (N_(13)-N_(18))conduction time was more than 7.53 msec.In addition,side-to-side value for(N_(13)-N_(18))were compared, these normally differ by less than 1.38 msec. The results may be summarized as followings: Acupuncture caused a reapperance of N_(18) in patients with absence of N_(18) and a decrease of the prolonged peak latencies by less than the upper limit of normal. Acupuncture obviously integrate the imbalance of side-to-side value for(N_(13)-N_(18))into normal range. Acupuncture exerted no significant effect on the SEPs of normal subject and patients without SEPs abnormalities.943|0|0更新时间：2023-08-11
