Objective Neurological diseases are closely associated with the apoptosis of neuronal cells .This article aims to study the inhibitory effect of taurine on the apoptosis of hippocampal neurons by activating Caspase 9 as well as its protective effect on the nervous system and its mechanisms . Methods Mouse hippocampal neuronal cells were randomly divided into four groups:control, injury and apoptosis, low-dose taurine protection, and high-dose taurine protection.The proliferation of the neuronalcells was observed, their apoptosis examined by MTT colorimetric assay, and the expression of Caspase 9 in different groups detected by immunofluorescence and Western blot. Results The injury and apoptosis group showed a poor proliferation of the hippocampal neuronal cells and decreased cell viability (A=0.102 ±0.025), significantly lower than the control group (relative A=0.643 ± 0.013), the low-dose taurine group (relative A=0.504 ±0.072), and the high-dose taurine group (relative A=0.452 ±0.029) ( all P<0 .05 ) .Immunofluorescence assay revealed significantly increased Caspase 9 activation in the injury and apoptosis group (A=61386.8 ±10083.6) compared with the control (A=4502.2 ±2518.1), the low-dose taurine (A=20077.4 ±4187.5), and the high-dose taurine group (A=13976.2 ±7044.1) (all P<0.05).Western blot showed a remarkably higher expression of Caspase 9 in in the injury and apoptosis group (A=1.23) than in the control (relative A=0.17), the low-dose taurine (A=0.21), and the high-dose taurine group (A=0.19) (all P<0.05). Conclusion Taurine can protect neuronal cells by inhibi-ting Caspase 9 activation.

Objective To explore the effect of thyroid hormone on bone metabolism.Methods The thyroid in the rabbits had been cut off and the physics and histology of the bone in the rabbits were observed.The therapeutic effect of exterofection thyroid hormone was also observed.Results The lacking or reducing of thyroid hormone could lead to osteoporosis.The substitutive treatment of T_4 could partially inhibit the oesteopenia.Conclusion When the T_3 level equals to the level of T_4,the oesteopenia of the rabbits with thyroid being cut off may be caused by the lack of calcitonin.

Low carbohydrate diet (LCD), as an adjunctive therapy of type 1 diabetes (T1DM), has attracted much attention in recent years, but its exact efficacy and safety have not yet been determined. Limited literature has reported that LCD plays an important role in controlling blood sugar and its complications in T1DM patients, regulating intestinal microbiota, and autoimmunity. This article elaborates on the research progress of T1DM medical nutritional therapy related to LCD mode in recent years, including its control of blood sugar, adverse reactions, and regulation of intestinal microbiota.

Traumatic supraorbital fissure syndrome (TSOFS) is a symptom complex caused by nerve entrapment in the supraorbital fissure after skull base trauma. If the compressed cranial nerve in the supraorbital fissure is not decompressed surgically, ptosis, diplopia and eye movement disorder may exist for a long time and seriously affect the patients′ quality of life. Since its overall incidence is not high, it is not familiarized with the majority of neurosurgeons and some TSOFS may be complicated with skull base vascular injury. If the supraorbital fissure surgery is performed without treatment of vascular injury, it may cause massive hemorrhage, and disability and even life-threatening in severe cases. At present, there is no consensus or guideline on the diagnosis and treatment of TSOFS that can be referred to both domestically and internationally. To improve the understanding of TSOFS among clinical physicians and establish standardized diagnosis and treatment plans, the Skull Base Trauma Group of the Neurorepair Professional Committee of the Chinese Medical Doctor Association, Neurotrauma Group of the Neurosurgery Branch of the Chinese Medical Association, Neurotrauma Group of the Traumatology Branch of the Chinese Medical Association, and Editorial Committee of Chinese Journal of Trauma organized relevant experts to formulate Chinese expert consensus on the diagnosis and treatment of traumatic supraorbital fissure syndrome ( version 2024) based on evidence of evidence-based medicine and clinical experience of diagnosis and treatment. This consensus puts forward 12 recommendations on the diagnosis, classification, treatment, efficacy evaluation and follow-up of TSOFS, aiming to provide references for neurosurgeons from hospitals of all levels to standardize the diagnosis and treatment of TSOFS.
