Microsurgerical anatomy of transcallosal-transchoroidal approach to the third ventricle / 中华神经医学杂志

Objective To supply microanatomic data for the application of the transcallosal-transchoroidal approach, and discuss its clinical value of this application. Methods Twelve adult cadaveric wet brains were carefully dissected under microscope with a magnification ranging for 4-10 times, and the anatomic features of the paracele, the choroids plexus, the choroidal fissure and the diatela were successively explored. Three adult cadaveric fresh heads were studied,simulating the procedures of the transcallosal-transchoroidal approach. Observation was performed on related anatomic structures, and measurement of relative parameter was taken, too. Results In the body of the lateral ventricle, the choroid plexus is located in the medial part of the floor. The choroidal fissure is a C-shaped natural cleft between the thalamus and the fomix, being white translucent membranes, and it could be identified by following the choroid plexus in the lateral ventricle. After carefully opening the taenia fornicis, the contents of the velum interpositum are exposed. The cavity of the third vertricle is reached through opening the roof of the third vertricle between the 2 internal cerebral veins. The distances between the coronal suture at the medial border of the brain and the callosal sulcus were (39.12±3.94) mm; the distances between the coronal suture at the medial border of the brain and the interventricular foramen were (61.53±4.02) mm; the distances between the posterior border of the interventricular foremen and the coalesced area of the fornix and the callosum were (28.65±2.23) mm; the AC-PC distances were (25.94±2.16) mm; the distances between the interventricular foremen and the corpus albicans were (19.62±1.79) mm. Conclusion As compared with other approaches to the third ventricle, the transcallosal-transchoroidal approach, which follows a natural route, is of advantages in few injury and wide exposure, we suggest, therefore, that the transcallosal-transchoroidal approach be extensively adopted in clinical neurosurgery.

Clinical observation on transcutaneous electrical acupoint stimulation for treatment of functional dyspepsia / 中国针灸

<p><b>OBJECTIVE</b>To compare the therapeutic effects of transcutaneous electrical point stimulation and medication on functional dyspepsia.</p><p><b>METHODS</b>Two hundred and fifty cases were randomly divided into an observation group and a control group, 125 cases in each group. The observation group was treated with transcutaneous electrical acupoint stimulation and oral administration of placebo, transcutaneous electrical stimulated at Zusanli (ST 36), Liangmen (ST 21), Taichong (LR 3) etc. The control group was treated with oral administration of Mosapride citrate dispersible tablets, Domperidone and Omeprazole and the placebo treatment of transcutaneous electrical acupoint stimulation, the stimulated position was 3-4 cm to the selected points of the observation group, the amount of the stimulation did not reach the treatment amount. The symptom score, the plasma motilin (MTL) concentration and the somatostatin (SS) concentration were observed before and after treatment of 3 courses.</p><p><b>RESULTS</b>All symptom scores after treatment were lower than that before treatment in the two groups, the scores of the upper abdominal pain, acid regurgitation, belching and abdominal distention in the observation group were significantly lower than that in the control group (P < 0.05, P < 0.01); the treatments of both two groups can increase the plasma MTL concentration and decrease the SS concentration (both P < 0.001), and the plasma MTL concentration in the observation group was significantly higher than that in the control group (P < 0.01), and the SS concentration was significantly lower than that in the control group (P < 0.05).</p><p><b>CONCLUSION</b>Transcutaneous electrical point stimulation can more reduce the symptoms of upper abdominal pain, acid regurgitation, belching and abdominal distention, etc. in the functional dyspepsia patients than medication treatment, and can increase the concentration of the plasma MTL and decrease the SS concentration, thus to improve the gastrointestinal motility.</p>

Anatomic and clinical study on transcallosal-interforniceal approach to third ventricle / 中华神经医学杂志

Objective To explore the microanatomic features of the transcallosal-interforniceal approach, and discuss the value of its clinical application. Methods Fifteen adult cadaveric head specimens were dissected by microsurgical anatomic skills to simulate the procedures of the transcallosal-interforniceal approach. Observation and measurement were performed on related anatomic structures. In clinical, 21 patients with the third ventricle tumors underwent tumor resection via the transcallosal-interforniceal approach. Results Using two points on the cortical surface as references that were located 5 and 7 cm anterior to the central sulcus respectively, mean values of related measurements on P5-foramen of Monro (FM) and P7-FM were obtained as follows: (1) the depth of the interhemispheric fissure was 38.46 and 37.62 ram; (2) the height of the corpus callosum was 7.18 and 7.78 nun; (3) the height of the septum pellucidum was 7.53 and 9.88 mm; (4) the thickness of the fornix was 4.72 and 5.16 mm. Under the operative microscope, the tumors were totally removed in 11 cases,subtotally in 8 cases, and partially in 2 cases. Conclusions The corridor of the transcallosal-interforniceal approach should be limited between the lines of P5-FM and P7-FM. The quantitative information obtained in this study permits the preservation of important anatomic structures in operation, such as the motor strip, genu of the corpus callosum, fornical commissure and anterior commissure. This approach is deserved to be applied generally for providing a quite large operative field,making total tumor removal easier, and decreasing the incidence of postoperative complications.

Observation on therapeutic effect of low energy He-Ne laser acupoint radiation on infantile cold / 中国针灸

<p><b>OBJECTIVE</b>To search for an effective therapy for infantile cold.</p><p><b>METHODS</b>Two hundred and fifty-five cases were randomly divided into a laser group (n = 130) and a medication group (n = 125). The laser group were treated with lower energy He-Ne laser radiation at Tiantu (CV 22), Renying (ST 9), Dazhui (CV 14), Fengmen (BL 12), etc. and the medication group were treated mainly with oral administration of Amantadine tablets. The therapeutic effect was assessed after treatment of 5 days.</p><p><b>RESULTS</b>The laser group in alleviation of cough, nasal obstruction, rhinorrhea, sputum sound were significantly better than the medication group (P < 0.001, P < 0.01); the cured rate was 68.5% in the laser group and 42.4% in the medication group, the former being better than the latter (P < 0.001).</p><p><b>CONCLUSION</b>The low energy He-Ne laser acupoint radiation has a significant therapeutic effect on infantile cold.</p>
