To study the gender differences of amount of neurons in the nodose ganglions of rats. Fourteen Sprague-Dawley rats (7 males and 7 females) were selected. Bilateral nodose ganglions were dissected and serial sections of nodose ganglion were cut in a cryostat, followed by Cresyl-violet staining for neurons. Eight to ten consecutive sections from mid-portion of each nodose ganglion sample, which represent the most neuron number per section, were counted and averaged. Gender difference in the amount of neurons in the nodose ganglions was compared. No gender difference of neuron numbers was found in either side of nodose ganglion (p > 0.05). However, average neuron number of nodose ganglions on the left side of male (654 ± 60) and female (616 ± 37) were significantly more than that on the right side of male (470 ± 22) and female (453 ± 40) respectively (p < 0.05). There is no gender difference in total neuron number of nodose ganglions between male and female rat. However, the neuron number in the left nodose ganglion is greater than that in the right one. The difference may be due to the fact that left and right nodose ganglion is receiving different visceral sensory impulses separately, which is associated with different physiological functions. Further work should be carried out with retrograde tracing on neurons of nodose ganglions in an animal model, which are directly related to laryngeal sensory transmission, in order to determine the gender difference in the neuron number and morphology related to laryngeal functions. © 2012 Association of Otolaryngologists of India.

BACKGROUND: Clinical studies have demonstrated that systemic mild hypothermia could significantly reduce the disability and mortality rate of patients with severe traumatic brain injury. In recent years, the researches about the treatment of spinal cord injury by mild hypothermia have been successively carried out. OBJECTIVE: To investigate the effects of mild hypothermia on nerve regeneration microenvironment after spinal cord injury and explore the possible underlying mechanism of nerve regeneration and functional recovery after spinal cord injury in rats. METHODS: Twenty out of sixty-seven rats were randomly selected as the sham group, and other rats were used to establish spinal cord injury models in T9 segment using modified Allen’s method. Three rats were excluded for failure in spinal cord injury induction and four rats for death during modeling. The rest 40 rats were randomly and evenly divided into the spinal cord injury and mild hypothermia groups (n=20 rats/group). The rats in the sham and spinal cord injury groups were placed in the operating table with normal temperature, making their rectal temperature at 37.0±0.5 "C for 72 hours. The rats in the mild hypothermia group were placed on ice blanket machine, making their rectal temperature at 34.0±0.5 "C for 72 hours, then the temperature was naturally rewarmed. RESULTS AND CONCLUSION: Compared with spinal cord injury group, the apoptosis index and the level of aquaporin 4/9 mRNA and protein expression in spinal cord injury tissue were all decreased, somatosensory evoked potential latency and amplitude were recovered, and the motor functional scores were increased in the mild hypothermia group. These results indicate that mild hypothermia play its protective effect on spinal cord injury through attenuating apoptosis of neural cells and decreasing aquaporin 4/9 mRNA and protein expression levels. © 2015, Journal of Clinical Rehabilitative Tissue Engineering Research.

Bone marrow mesenchymal stem cells (BMSCs) play an important role in repairing nerve injury, meanwhile external temperature has significant effect on BMSCs transplantation, proliferation, and differentiation. To investigate the effect of BMSCs transplantation and mild hypothermia on repair of rat spinal cord injury (SCI). Forty-five female adult SD rats (weighing 200-250 g) were made the models of hemitransection SCI and divided randomly into 3 groups according to different treatments: group A (SCI group), group B (BMSCs transplantation group), and group C [BMSCs transplantation combined with mild hypothermia (33-35 degrees C) group]. At 1, 2, 4, 6, and 8 weeks after injury, the function of hind limb was evaluated with Basso Beattie and Bresnahan (BBB) score and inclined plane test. At 4 weeks after injury, histopathology and BrdU immunohistochemistry staining were performed. At 8 weeks after injury, horseradish peroxidase (HRP) retrograde nerve trace and transmission electron microscope (TEM) testing were performed to observe the regeneration of axon. After 4 weeks, the function of hind limb obviously recovered in groups B and C, there were significant differences in BBB score between groups B, C and group A (P < 0.05), between group B and group C (P < 0.05). There was no significant difference (P > 0.05) in tilt angle among 3 groups after 1 and 2 weeks, and there were significant differences (P < 0.05) among 3 groups after 4 weeks. HE staining showed that significant cavity could be seen in group A, little in group B, and no cavity in group C. BrdU immunohistochemistry staining showed that the number of positive cells was 0, 90.54 +/- 6.23, and 121.22 +/- 7.54 in groups A, B, and C, respectively; showing significant differences (P < 0.01) among 3 groups. HRP retrograde neural tracing observation showed that the number of HRP positive nerve fibers was 10.35 +/- 1.72, 43.25 +/- 2.65, and 84.37 +/- 4.59 in groups A, B, and C, respectively, showing significant differences (P < 0.01) among 3 groups. TEM observation showed that a great amount of unmyelinated nerve fibers and myelinated nerve fibers were found in central transverse plane in group C. The BMSCs transplantation play an important role in promotion of recovering the function of hind limb after SCI, and mild hypothermia has synergism effects.

To investigate whether there is a difference in carbohydrate antigen 19-9 (CA19-9), carcinoembryonic antigen (CEA), carbohydrate antigen 72-4 (CA72-4), and neuron-specific enolase (NSE) between diabetic and non-diabetic patients.Methods: A retrospective analysis was performed in 268 type 2 diabetic patients and 95 non-diabetic ones, and their serum levels of CA19-9, CEA, CA72-4, and NSE were compared in our endocrine ward at the Tianjin Fourth Central Hospital, Tianjin, Chinaduring the period from January to June 2015. The diabetic patients were divided into 4 groups based on glycosylated hemoglobin (HbA1c) levels to investigate the relationship between levels of tumor markers and glucose status.Results: Diabetic patients had higher levels of tumor markers than non-diabetic subjects (CA19-9: 13.0 versus 7.25U/mL, p=0.000; CEA: 2.55 versus 2.25 ng/mL, p=0.012; CA72-4: 1.95 versus 1.50U/mL, p=0.001; NSE: 11.64 versus 10.22ng/mL, p=0.000). CA19-9 levels increased in a stepwise manner with poor diabetes status. CEA levels were increased in patients with HbA1c 9% and CA72-4 elevation was predominant in patients with poor glycemic control (HbA1c 11%). NSE levels were not associated with metabolic parameters.Conclusion: Serum levels of CA19-9, CEA, CA72-4, and NSE were elevated in type 2 diabetes; however, only CA19-9, CEA, and CA72-4 levels were associated with hyperglycemia.

Following successful establishment of a rat model of spinal cord hemisection injury by resecting right spinal cord tissues, bone marrow stem cells were transplanted into the spinal cord lesions via the caudal vein while maintaining rectal temperature at 34 0.5C for 6 hours (mild hypothermia). Hematoxylin-eosin staining showed that astrocytes gathered around the injury site and formed scars at 4 weeks post-transplantation. Compared with rats transplanted with bone marrow stem cells under normal temperature, rats transplanted with bone marrow stem cells under hypothermia showed increased numbers of proliferating cells (bromodeoxyuridine-positive cells), better recovery of somatosensory-evoked and motor-evoked potentials, greater Basso, Beattie, and Bresnahan locomotor rating scores, and an increased degree of angle in the incline plate test. These findings suggested that hypothermia combined with bone marrow mesenchymal stem cells transplantation effectively promoted electrical conduction and nerve functional repair in a rat model of spinal cord hemisection injury.
