Objective:To explore the role of diffusion tensor imaging (DTI) in monitoring prognosis after contralateral C7 nerve transfer in patients with central paralysis.Methods:The clinical data of a 56-year-old male patient with right limb motor impairment after cerebral infarction, admitted to the Department of Neurosurgery at Brain Hospital of Hunan Province in October 2023, were retrospectively analyzed. The patient had experienced right limb motor dysfunction for over 2 years following a cerebral infarction and was treated with contralateral C7 nerve transfer. Follow-ups were conducted at 2 and 6 months postoperatively. Motor function was assessed using the Fugl-Meyer Assessment (FMA) and Activities of Daily Living (ADL) scale, while changes in fractional anisotropy (FA) in the lesion area and corticospinal tract were monitored via DTI.Results:Postoperative follow-up of patient showed: (1) Significant improvement in motor function: ADL scores increased from 65 preoperatively to 75 (2 months postop) and 80 (6 months postop); FMA scores increased from 46 to 58 (2 months postop) and 61 (6 months postop). Muscle tension in the affected upper limb decreased markedly, and range of motion in the right shoulder joint improved. (2) Imaging improvements: DTI revealed an increase in FA values from 0.157 to 0.174 in the lesion area and from 0.52 to 0.53 in the corticospinal tract, indicating partial restoration of neural tract integrity.Conclusions:Contralateral C7 nerve transfer can effectively improve motor function in stroke patients. DTI technology provides an objective imaging basis for clinically assessing functional recovery by quantitatively evaluating changes in neural tract integrity, demonstrating significant value in guiding rehabilitation.

Objective:To investigate the clinical effect of deep brain stimulation (DBS) in the treatment of Parkinson′s disease (PD).Methods:32 PD patients treated in Hunan Brain Hospital from January 2016 to December 2018 were selected for the study. Guided by MRI and supplemented by electrophysiological stimulation to correct the target, PD patients were treated with DBS for the nucleus accumbens. Based on Webster and Unified Parkinsons Disease Rating Scale (UPDRS) scores before and after DBS treatment, the clinical treatment effects were evaluated. And the content of Aβ1-42, interleukin (IL)-1β, IL-6, uric acid (UA), malondialdehyde (MDA), homocysteine (Hcy), S-nitrosylated dynamin-relatedprotein 1 (SNO-Drp1) and Drp1 was measured before and after DBS treatment. The ratio of SNO-Drp1/Drp1 was also measured.Results:The Webster score and UPDRS score of PD patients after DBS treatment were lower than those before DBS treatment ( P<0.05). The Aβ1-42 and Drp1content of PD patients after DBS treatment was higher than that before DBS treatment ( P<0.05), while the content of IL-1β, UA, MDA, Hcy and the ratio of SNO-Drp1/Drp1 were lower than before treatment ( P<0.05). Conclusions:DBS has confirmed a good clinical effect in the treatment of PD patients and significantly improved the quality of life of patients.

Objective:To investigate the effect of vagus nerve stimulation (VNS) on serum cytokines and neurotransmitters in epilepsy patients with depression.Methods:From March 2015 to 2018, 13 patients with epilepsy combined with depression undergoing VNS surgery in Brain Hospital of Hunan Province were selected as the research objects. The surgical efficacy, depression degree, serum cytokines and neurotransmitter changes before operation, 6 months and 12 months after operation were compared.Results:The effective rate of epilepsy treatment at 6 and 12 months after VNS were 61.5%(8/13) and 76.9%(10/13), respectively. After 6 months and 12 months, Hamiton Depression scale (HAMD) and self-rating depression scale (SDS) scores were significantly lower than those before operation ( P<0.05 or P<0.01). At 6 months after operation, serum 5-hydroxytryptamine (5-HT) level was significantly higher than that before operation, while serum interleukin (IL)-1α, IL-6 and tumor necrosis factor α (TNF- α) were significantly lower than those before operation ( P<0.05 or P<0.01). At 12 months after operation, 5-HT and dopamine (DA) were significantly increased, while IL-1 α, IL-2, IL-6 and TNF -α were significantly decreased ( P<0.05 or P<0.01). Conclusions:VNS may can improve epilepsy and depression by regulating the level of neurotransmitter and serum cytokines.

Psychiatric symptoms are common after traumatic brain injury (TBI), and some patients have poor drug therapeutic efficacy. We report a successfully treated case of psychiatric symptoms after TBI using deep brain stimulation (DBS) to the anterior limb of internal capsule (ALIC)-nucleus accumbens (NAc) in a 76-year-old woman. The patient suffered from auditory hallucination, mood changes, and insomnia caused by TBI. Psychological test assessment showed the scores of Hamilton Anxiety Scale, Hamilton Depression Scale and Positive and Negative Syndrome Scale were 30, 35, and 96 respectively. Head magnetic resonance imaging scan showed right temporal lobe encephalomalacia. Head magnetic resonance spectroscopy (MRS) showed bilateral basal ganglia choline increased relatively. After DBS to the ALIC-NAc, the target parameters were adjusted. The psychiatric symptoms were completely improved and the result of head MRS was normal in the end. The current report declares that DBS is reversible, adjustable and safe in the treatment of psychiatric symptoms caused by TBI. DBS to the ALIC-NAc should be considered as a possible treatment choice once a patient showed psychiatric symptoms after TBI.

Objective: To observe influences of Chaihu-Longgu-Muli decoction (CLMD) on electroencephalogram (EEG), serum nerve growth factor (NGF) and brain derived neurotrophie factor (BDNF) level of patients with temporal lobe epilepsy. Methods: Single blind randomized controlled trial design was used. 138 patients with temporal lobe epilepsy were divided into oxcarbazepine group (including 67 patients), oxcarbazepine+ CLMD group (including 71 patients). After 28 d of treatment, EEG changes, NGF and BDNF changes in serum, and relevant serological indicator inspection of drug reactions in both groups were observed. Results: The effective rate of EEG in oxcarbazepine+ CLMD group was 81.8%, which was obviously higher than the oxcarbazepine group (50.7%), with significant difference (P<0.01). After treatment, NGF and BDNF of both groups were higher than those before treatment (P<0.05). Moreover, serum NGF and BDNF of oxcarbazepine+ CLMD group were higher than the oxcarbazepine group (P<0.05). There was no statistical significance in serological indicator of drug reactions in both groups (P>0.05). Conclusions The curative effects of oxcarbazepine+ CLMD is superior to the individual oxcarbazepine and it can obviously enhance serum NGF and BDNF of patients with temporal lobe epilepsy and reduce the status epilepticus of patients with temporal lobe epilepsy and it has the high safety.

OBJECTIVE: To determine the clinical characteristics and cognitive dysfunction of bipolar depression and unipolar depression. METHODS: Fifty patients with unipolar depression, 48 bipolar depression, and 50 normal controls were assessed with Hamilton Depression Scale, Hamilton Anxiety Scale, Life Events Scale, and The Wisconsin Card Sorting Test. General demographic data, clinical data, and the scores of recognitive function in the 3 groups were compared. RESULTS: The patients with bipolar depression occured at young age and had obvious family history compared with those with unipolar depression. The patients with bipolar or unipolar disorders had lower scores in most neuropsychological tests than those in the control group (P<0.05). The patients with bipolar depression in understanding memory and Wisconsin card sorting test were worse than those with unipolar depression (P<0.05). CONCLUSION There is cognitive dysfunction in patients with bipolar or unipolar disorder. Understanding memory and executive function damage may be cognitive features in bipolar disorder.

ObjectiveTo investigate the etiology, clinical characteristics, diagnosis and treatment of regional portal hypertension caused by left upper abdominal malignant tumors.MethodsFrom January 2006 to December 2009, a total of 8 patients presenting regional portal hypertension were treated at our hospital, whose clinical data were analyzed retrospectively. ResultsPancreatic tumors (5/8) and retroperitoneal tumors(3/8)were the primary etiology,andthe main symptoms included upper gastrointestinal bleeding and irregular left upper abdominal pain.Isolated gastric varices were the most distinct clinical features. All patients underwent multi-visceral resection including pancreatic body and tail and spleen. Tumor involved stomach, left kidney, left adrenal and splenic flexure of colon were also removed en bloc. During the follow-up period there was no recurrent upper gastrointestinal bleeding, one patient died and two patients developed metastasis or tumor local recurrence.ConclusionRegional portal hypertension caused by malignant tumor was relatively rare,aggressive resection of multi-viscera combined with devascularization was an effective therapy.

OBJECTIVE: To determine the long-term effect and security of refractory schizophrenia with brain stereotaxis multi-target therapy technique. METHODS: A total of 87 patients with refractory schizophrenia were treated with brain stereotaxis multi-target therapy and were followed up over 2 years. The scores of Clinical Global Impression, Brief Psychiatric Rating Scale, Positive and Negative Symptom Scale, Wechsler Adult Intelligence Scale, Wechsler Memory Scale, Actives of Daily Living, and Social Disability Screening Schedule were compared before and after the operation. RESULTS: Of the 87 patients, 40 obviously improved, 24 improved, 12 improved little, 7 did not change. None grew worse, 1 died, and 3 shed. There was a significant difference in the scales before and after the operation (P<0.01). No severe complications and sequelae occurred. CONCLUSION Stereotaxic multi-target therapy is effective and safe for refractory schizophrenia. After the operation, drug therapy should be maintained and recovery of social function is helpful.
