Three Chinese adult brains were selected for the study of the histological struc-ture of the cerebral cortex of the Broca's area with a comparison between thecorresponding parts of both hemispheres.Nissl's staining,Weil's and Golgi's techniqueswere employed for the microscopic examination.The results are as follows:(1)The thickness of the cortex of the Broca area in the specimen stained byM?lligan's method is in the range of 3.5 mm to 5.0 mm.(2)The thickness measurements of the six layers in the thickest cortex are 0.17mm(Ⅰ),0.11 mm(Ⅱ),1.06 mm(Ⅲ～Ⅴ),1.52 mm(Ⅵ)and in total 2.86 mm inthe left hemisphere,and 0.15 mm(Ⅰ),0.10 mm(Ⅱ),0.87 mm(Ⅲ～Ⅴ),1.50 mm(Ⅵ),and in total 2.62 mm in the right hemisphere respectively.(3)The ratio of height/width of pyramidal cells in the second layer are 16.84?4.46 ?m/9.50?2.32 ?m in the left hemisphere and 15.60?4.56 ?m/8.88?2.03 ?min the right hemisphere respectively.(4)The ratio of the height/width of the pyramidal cells in the fifth layer are56.90?7.99 ?m/14.79?3.26 ?m in the left hemisphere and 49.80?9.08 ?m/14.67?7.88 ?m in the right hemisphere respectively.There is a very significant difference(P0.05)betweenthe widths of the pyramidal cells of the two hemispheres.(5)Within an area of 6400 ?m~2 of a section 10 ?m in thickness,in the firstmolecular layer,there are 13.0 cells in the left hemisphere and 11.7 cells in the righthemisphere respectively.(6)In this area all of the pyramidal cells are not exceeding 60 ?m in height,hence there is no Betz cells.In addition to the large population of pyramidal cells,there are cajal horizontal cell,Martinotti cells,fusiform cells,etc.

The total glucosides of paeony root ( TCP ) extracted from paeony root of Boxian county, Anhui province was studied on the immunoregulatory effects in mice.The delayed hypersensitivity (DH) was increased by TGP at dose of 200mg/kg/d ig for 8d in the normal 6l5 mouse. Both depressed DH & enhanced DH induced by cyclophosph-amid ( Cy ) were restored by TGP ( 5 mg/kg/d ip x 5 - 8 d) in ICR mice. The decreased hemolysin antibody formation of spleen induced by Cy in BALB/c mice immunized with SRBC was raised by TGP ( 5mg /kg/d ip x 4d) . The phagocytic activity of ICR mice peritoneal macrophage on chiken RBC . In addittion, it was considerably Stimulated by using ip TGP at dose of 40mg/kg/d for 3d. The results suggested that TGP might possess the immunoregulatory effects in mice.

The appearance and changes of Acetylcholinesterase (ACHE) in the brains of 62 rats from early embryos to adults were studied by histochemical method and the brains of 19 rats of corresponding stages were examined with Nissl stain. The main results are as follows:1. AChE appeared in the following sequence: spinal cord, myelencephalon, metencephalon, mesencephalon, diencephalon and finally in telencephalon. In telencephaIon, AChE appeared earlier in paleocortex than in neocortex. The sequence described above showed that the appearance of AChE reflects cephalization of the nervous system in the rat.2. AChE-positive neurons of the rat brain consisted of cholinergic neurons and cholinoceptive ceils, both of which are related to the neurotransmitter ACh.3. The following nuclei of adult rat brain were shown to be AchE-positive in our specimens, but had not been reported in available literature: n. tractus mesencephali, n. anterior dorsalis thalami, n. anterior ventralis thalami, n. lateralis thalami, n. habenulae lateralis, n. reticularis thalami, n. supraopticus, n. paraventricularis, n. parafascicularis and n. ruber. In the cerebral cortex very few positive cells have been noticed.

Objective: To investigate the effects of dendritic cells(DCs) loaded with tumor antigens on the proliferation and antitumor activity of tumor-infiltrating lymphocytes(TILs) from hepatocellular carcinoma (HCC) in vitro . Methods:DCs derived from the peripheral blood of patients with HCC were loaded with autologous tumor lysate(Tuly) to generate DC-Tuly and then the DC-Tuly was co-cultured with autologous TILs in low concentration of IL-2. TILs were counted, and the phenotypes of DCs and TILs were assayed by FCM and the cytotoxicity of TILs was determined with LDH method. The concentration of cytokines in TILs culture supernatant such as IFN-? and TNF-? was detected by ELISA . Results: The expression levels of CD1a, CD80, CD83,CD86, CD40, HLA-DR molecules on the DC-Tuly are notably increased( P

Objectives:To explore the effect and possible mechanisms of mild hypothermia on interferon(IFN)-α2b-induced AC16 cardiomyocytes apoptosis. Methods:Cardiomyocytes were stimulated in ordinary temperature and mild hypothermia by IFN-α2b under different concentrations for different times.Proliferation activity of cardiomyocytes was detected by CCK-8 assay.Apoptosis was detected by flow cytometry technique.The effects of different interventions on mitochondrial morphology were examined using Mito-Tracker Green and laser scanning confocal microscope,respectively.The mitochondrial membrane potentials under different intervention conditions were detected by flow cytometry.The fusion of dynamin-related protein 1(Drp1)and mitochondria,and the effects of different interventions on the mitochondria was examined by Drp1 or mitochondrial fluorescent probes and laser scanning confocal microscope.The effects of different intervention conditions on the protein expression level of Phospho-Drp1(p-Drp1)Ser616,Drp1,cleaved poly ADP-ribose polymerase1(cleaved-PARP1),poly ADP-ribose polymerase1(PARP1)were detected by Western blot. Results:CCK-8 assay and flow cytometry results showed that IFN-α2b inhibited the proliferation and enhanced the apoptosis of AC16 cardiomyocytes in a time and dose-dependent manner,these effects could be attenuated by mild hypothermia.Mito-Tracker Green,laser scanning confocal microscope and flow cytometry results showed that the extent of damage of mitochondria with different interventions were attenuated in the setting of mild hypothermia as compared with ordinary temperature.The morphology of mitochondria remained intact and the mitochondrial membrane potentials were the highest in mild hypothermia group.Injured AC16 cardiomyocytes released Drp1 from cytoplasm to mitochondria and increased mitochondrial fission,these effects were abolished after mild hypothermia.p-Drp1 Ser616/Drp1 ratio and cleaved-PARP1/PARP1 ratio were decreased after mild hypothermia,and above effects could be reversed by mitochondrial division inhibitor-1(Mdivi-1)pretreatment. Conclusions:Mild hypothermia inhibits IFN-α2b-induced AC16 cardiomyocytes apoptosis via improving mitochondrial function.

Purpose: Whether craniospinal irradiation (CSI) could be replaced by limited-field radiation in non-metastatic bifocal germinoma remains controversial. We addressed the issue based on the data from our series and the literature. Methods: Data from 49 patients diagnosed with non-metastatic bifocal germinoma at our hospital during the last 10 years were collected. The Pediatric Quality of Life Inventory 4.0 was used to evaluate health-related quality of life (HRQOL). Additionally, 81 patients identified from the literature were also analyzed independently. Results: In our cohort, 34 patients had tumors in the sellar/suprasellar (S/SS) plus pineal gland (PG) regions and 15 in the S/SS plus basal ganglia/thalamus (BG/T) regions. The median follow-up period was 52 months (range, 10 to 134 months). Our survival analysis showed that patients treated with CSI (n=12) or whole-brain radiotherapy (WBRT; n=34) had comparable disease-free survival (DFS; p=0.540), but better DFS than those treated with focal radiotherapy (FR; n=3, p=0.016). All 81 patients from the literature had tumors in the S/SS+PG regions. Relapses were documented in 4/45 patients treated with FR, 2/17 treated with whole-ventricle irradiation, 0/4 treated with WBRT, and 1/15 treated with CSI. Survival analysis did not reveal DFS differences between the types of radiation field (p=0.785). HRQOL analysis (n=44) in our cohort found that, compared with S/SS+PG germinoma, patients with BG/T involvement had significantly lower scores in social and school domains. However, HRQOL difference between patients treated with CSI and those not treated with CSI was not significant. Conclusion In patients with non-metastatic bifocal germinoma, it is rational that CSI could be replaced by limited-field radiation. HRQOL in patients with BG/T involvement was poorer.

Objective:To investigate the application of virtual reality (VR) technology on intraoperative pain in patients undergoing peritoneal dialysis (PD)-related procedures with local infiltration anesthesia and the satisfaction.Methods:It was a single-center, prospective, concurrent controlled study. Patients were divided into two groups: VR group and control group. In the VR group, patients wore a VR headset to watch soothing audio and video content during surgery, while the control group underwent routine procedures. Intraoperative pain and satisfaction were assessed using the visual analog scale (VAS) and a 5-point satisfaction scale within 30 minutes of surgery. In addition, tolerance of the VR experience in the VR group was assessed using the VR sickness questionnaire.Results:A total of 43 patients were included in the study, including 25 males (58.1%). Chronic glomerulonephritis [17 cases (39.5%)] and diabetic nephropathy [6 cases (14.0%)] were the main primary diseases. There were 23 cases in the control group and 20 cases in the VR group. There were no significant differences between the two groups in age, sex ratio, proportion of primary disease, diabetes, hypertension, distribution of operation methods, preoperative vital signs and operation time (all P>0.05). VAS pain score was significantly lower in the VR group than that in the control group (5.90±2.38 vs. 7.43±1.67, t=2.469, P=0.018). The percentage of patients who were satisfied was 89.5% (17/19) in the VR group and 78.3% (18/23) in the control group, but there was no significant difference (chi-square test for continuity correction, χ2=0.308, P=0.579). Three patients in the VR group withdrew from the study due to severe discomfort, while the remaining participants found the VR experience to be tolerable. Common adverse effects included fatigue and blurred vision. Conclusions:The application of VR technology in PD-related procedures has been effective in reducing intraoperative pain when combined with local infiltration anesthesia. Furthermore, the utilization of VR technology in PD-related procedures is associated with a safe and tolerable outcome, despite the observation of some adverse effects.
