ABSTRACT
Post-stroke depression (PSD) is a serious and common complication of stroke, which seriously affects the rehabilitation of stroke patients. To date, the pathogenesis of PSD is unclear and effective treatments remain unavailable. Here, we established a mouse model of PSD through photothrombosis-induced focal ischemia. By using a combination of brain imaging, transcriptome sequencing, and bioinformatics analysis, we found that the hippocampus of PSD mice had a significantly lower metabolic level than other brain regions. RNA sequencing revealed a significant reduction of miR34b-3p, which was expressed in hippocampal neurons and inhibited the translation of eukaryotic translation initiation factor 4E (eIF4E). Furthermore, silencing eIF4E inactivated microglia, inhibited neuroinflammation, and abolished the depression-like behaviors in PSD mice. Together, our data demonstrated that insufficient miR34b-3p after stroke cannot inhibit eIF4E translation, which causes PSD by the activation of microglia in the hippocampus. Therefore, miR34b-3p and eIF4E may serve as potential therapeutic targets for the treatment of PSD.

Traumatic cerebrospinal fluid leakage commonly presents in traumatic brain injury patients, and it may lead to complications such as meningitis, ventriculitis, brain abscess, subdural hematoma or tension pneumocephalus. When misdiagnosed or inappropriately treated, traumatic cerebrospinal fluid leakage may result in severe complications and may be life-threatening. Some traumatic cerebrospinal fluid leakage has concealed manifestations and is prone to misdiagnosis. Due to different sites and mechanisms of trauma and degree of cerebrospinal fluid leak, treatments for traumatic cerebrospinal fluid leakage varies greatly. Hence, the Craniocerebral Trauma Professional Group of Neurosurgery Branch of Chinese Medical Association and the Neurological Injury Professional Group of Trauma Branch of Chinese Medical Association organized relevant experts to formulate the " Chinese expert consensus on the diagnosis and treatment of traumatic cerebrospinal fluid leakage in adults ( version 2023)" based on existing clinical evidence and experience. The consensus consisted of 16 recommendations, covering the leakage diagnosis, localization, treatments, and intracranial infection prevention, so as to standardize the diagnosis and treatment of traumatic cerebrospinal fluid leakage and improve the overall prognosis of the patients.
ABSTRACT
Pituitary adenoma is one common type of intracranial tumors, accounting for about 10% of intracranial tumors. Although pituitary adenomas are benign tumors, the complete resection and recurrence prevention remain challengeable due to aggressive growth of tumor, limited equipment conditions and surgical techniques of the surgeon. The proportion of recurrent pituitary adenomas is rising year by year and the difficulty of treatment also increases. This article reviews the diagnosis and treatment of recurrent pituitary adenomas based on the summary data of invasive or recurrent pituitary adenomas cases in our center, including indication for the second transsphenoidal surgery, surgical techniques, and prevention and treatment of postoperative complications, to provide reference for clinicians in this field.
ABSTRACT
Objective:To explore the clinical features, surgical treatments and treatment effects of children with skull defect.Methods:Sixty children with skull defect, admitted to our hospital from January 2010 to December 2020, were chosen in our study. These children were divided into encephalocele group ( n=28) and non-encephalocele group ( n=32) according to the imaging results (whether brain tissues were 1.5 cm higher than the bone window plane or not). The time and area of skull defect were compared between the two groups. Titanium mesh or polyether ether ketone material were used to repair the skull defect; 24 children without nerve fiber bundle distribution from encephalocele group underwent resection of the encephalocele tissues additionally. All children were followed up for 3-10 years in the outpatient department, and the prognoses of children from the two groups were evaluated by Glasgow Outcome Scale (GOS) one year after surgery. Results:As compared with the non-encephalocele group, children in the encephalocele group had significantly younger age accepted skull removal, significantly longer skull defect course, significantly higher incidence of epilepsy, significantly more common secondary changes in the brain tissues around the defect, but statistically smaller skull defect area ( P<0.05). There was no bleeding, severe edema, wound infection or cerebrospinal fluid leakage after surgery in both groups, and primary healing was achieved. In the encephalocele group, 16 children were complicated with epilepsy; 10 got complete seizure control, and 6 got seizure improvement. In the non-encephalocele group, 8 children were complicated with epilepsy; 6 got complete seizure control, and 2 got seizure improvement. Postoperative follow-up showed that GOS scores in the non-encephalocele group were significantly higher than those in encephalocele group ( P<0.05). Conclusion:As ompared with skull defect children without encephalocele, skull defect children with encephalocele have earlier defect age, longer course of disease, higher incidences of ventricular perforation malformation and epilepsy, and a relatively poorer prognosis.
ABSTRACT
Objective To explore the management of spontaneous intraspinal hematoma.Methods From January 2011 to July 2018,29 cases with spontaneous intraspinal hematoma were admitted to our department.Date on etiology,clinical presentation,radiological features,treatment strategy and prognosis were analyzed retrospectively.The prognosis was assessed by American Spinal Injury Association impairment scale (ASIA) before and after the treatment.Results Total of 29 cases,only 10 cases (34.5％) revealed specific etiology,including 7 cases of spinal vascular malformation,2 of tumor apoplexy,1 of cavernous hemangioma.After 2 weeks of conservative treatment,3 patients with grade D and 3 patients with grade E were assessed for spinal function.The average interval from onset to surgery was(9.4±7.5) days,the ASIA after two weeks of the operation was as follows:5 patients were assessed at grade A,5 patients at grade C,8 patients at grade D and 4 patients at grade E.28 patients were followed up for (48.7±23.1) months on average,6 patients without surgery were E,22 cases with surgery were as follows:4 cases A,18 cases D/E.Conclusions The etiology of spontaneous intraspinal hematoma is hard to define even after complete preoperative examination and exploratory operation.The preoperative neurologic functions are important predicting factors for the prognosis of spontaneous intraspinal hematoma.For patients who had neurologic function deficit,surgical treatment should be performed urgently to remove the hematoma and release the decompression of spinal cord.The majority of these patients can achieve a positive prognosis after surgery.
ABSTRACT
Objective To analyze the effect of clinical application of ultrasound in microsurgical treatment of intramedullary tumors in the superior cervical spinal cord.Methods Retrospective study the clinical data of 15 patients with intramedullary tumors in the superior cervical spinal cord,which were underwent a laminectomy for microsurgical tumor resection during January,2014 and January,2018.Intraoperative ultrasound and neuromonitoring was accompanied by the whole surgical procedure for each case.The follow-up data was collected by outpatient department visits and telephone interviews.Results All the described patients were performed with microscopic tumor resection by using intraoperative neurophysiological monitoring and ultrasound.The pathological diagnosis was ependymocytoma (n=8) and astrocytoma (n=7).Gross total resections comprised 86.7％ of cases (n=13),and subtotal resections 13.3％ (n=2).The neurological outcome was as follows:Mc-Cormick scale grade Ⅰ,10 patients;grade Ⅱ,3 patients;grade Ⅲ,1 patient;and grade Ⅳ 1 patient;Follow-up was applied for (19.2±7.6) months in 13 cases and 12.0 months in 2 cases.Compared to the preoperative period,66.6％ of patients recovered postoperatively,20.0％ improved,6.7％ remained without deficit and deterioration persisted in 6.7％.Conclusion The microscopic resection of tumors is the effective way to cure this disease.By using intraoperative neurophysiological monitoring and ultrasound,the complete tumor resection and the minimal spinal cord injury were certainly achieved.
ABSTRACT
A growing number of children and adolescents are being diagnosed as Chiari malformation type Ⅰ (CM-Ⅰ) for behavioral disorders,developmental delay,seizures,or abnormal orpharyngeal function.The aim of this study was to compare the clinical characteristics,imaging findings and surgical outcomes of CM-Ⅰ in pediatric and adult patients.Between January 2014 and June 2017,84 patients with CM-Ⅰ underwent surgical treatment in our department.We divided the patients into two groups:pediatric group (n=1 1,age ＜18 years)and adult group (n=73,age ≥18 years).Data on clinical characteristics,imaging findings,surgical outcomes,and prognosis were retrospectively reviewed and compared between these two groups.For clinical presentation,scoliosis (36.4％) and developmental delay (36.4％) were more common in pediatric patients,whereas,sensory disturbance (58.9％) and motor weakness (41.1％) were more common in adult patients.Imaging findings showed that the incidence of hydrocephalus and craniovertebral junctional abnormalities was significantly higher in pediatric group than in adult group (P＜0.05).Compared to adult group,pediatric group showed a better improvement or resolution of syrinx and tonsillar herniation after surgical treatments (P＜0.05).The total Chicago Chiari Outcome Scale (CCOS) score in pediatric patients at the last follow-up was significantly higher than that in adult patients (P=0.002).In conclusion,the clinical characteristics and imaging findings appeared to be different in pediatric and adult patients with CM-Ⅰ.The surgical outcomes of pediatric patients were shown to be significantly better than those of adult patients.

ABSTRACT
Fertility preservation is a hotspot of research in reproductive medicine, and that of male adolescent cancer patients is drawing even more attention from reproductive and oncologic clinicians. Both cancer and its treatment can decrease semen quality and even induce irreversible damage to fertility. Sperm cryopreservation is an effective method for fertility preservation. In the past few years, marked advances have been made in the cryopreservation, transplantation, and in vitro culture of testis tissue and stem spermatogonial cells. Although still experimental, these approaches may offer some options to those with no mature sperm in the testis. Unfortunately, very few people know and participate in the studies of fertility preservation and the utilization rate of cryopreserved sperm remains low. Therefor reproductive physicians and oncologists are required to make more efforts to search for effective fertility preservation methods for male adolescent cancer patients.

Industrialization and environmental pollution are bringing more problems to human reproduction and increasing the prevalence of male infertility. Western medicine has shown its limitations in the management of male infertility, especially that of oligoasthenospermia. Traditional Chinese medicine (TCM), however, has long and rich experiences in the treatment of oligoasthenospermia, with a large variety of medicinal prescriptions based on the TCM theories, among which Qilin Pills shows a particularly significant therapeutic effect on oligoasthenospermia, especially when combined with Western medicine. At present, published studies on Qilin Pills are mainly in the stage of clinical observation, while basic researches and studies on its relevant mechanisms are rarely seen.

Objective@#To study the protective effect of Qilin Pills (QLP) on the reproductive function of rats with oligoasthenospermia (OAS) induced by tripterygium glycosides.@*METHODS@#Twenty-eight male SD rats were randomly divided into a normal control, an OAS model control, a low-dose QLP, and a high-dose QLP group of equal number. OAS models were made in the latter three groups by intragastrical administration of tripterygium glycosides at 40 mg per kg of the body weight per day, and meanwhile the animals in the low- and high-dose QLP groups were treated with QLP at 1.62 and 3.24 g per kg of the body weight per day, respectively, while those in the OAS model group with normal saline, all for 30 consecutive days. Then all the rats were executed for obtaining the testis weight, testis viscera index, epididymal sperm concentration and motility, reproductive hormone levels, and antioxidation indexes and observation of the histomorphological changes of the testis tissue by HE staining.@*RESULTS@#After 30 days of intervention, the low- and high-dose QLP groups, as compared with the OAS model controls, showed significantly improved epididymal sperm concentration (［14.57 ± 3.95］ and ［39.71 ± 11.31］ vs ［4.71 ± 1.25］ ×10⁶/ml, P <0.05) and motility (［3.71 ± 1.11］ and ［4.29 ± 1.80］ vs ［0.57 ± 0.53］%, P <0.05), increased levels of sex hormone binding globulin (SHBG) (［94.83 ± 11.17］ and ［88.05 ± 9.21］ vs ［56.74 ± 8.29］ nmol/L, P <0.05) and free testosterone (FT) (［27.27 ± 3.63］ and ［32.80 ± 2.51］ vs ［22.81 ± 2.75］ nmol/L, P <0.05), decreased level of follicle-stimulating hormone (FSH) (［1.49 ± 0.62］ and ［1.12 ± 0.83］ vs ［1.71 ± 0.52］ mIU/ml, P <0.05), but no significant change in the total testosterone (TT) level. Meanwhile, the level of superoxide dismutase (SOD) was markedly elevated in the low- and high-dose QLP groups in comparison with the OAS model control group (［277.14 ± 15.84］ and ［299.60 ± 20.83］ vs ［250.04 ± 31.06］ U/ml, P <0.05) while that of reactive oxygen species (ROS) remarkably reduced (［397.61 ± 62.71］ and ［376.84 ± 67.14］ vs ［552.20 ± 58.07］ IU/ml, P <0.05). HE staining showed that QLP intervention significantly increased the layers and quantity of spermatogenic cells in the testicular seminiferous tubules of the OAS rats.@*CONCLUSIONS@#QLP can effectively protect the reproductive system of oligoasthenospermia rats by raising sperm quality, elevating reproductive hormone levels, reducing oxidative stress injury, and improving histomorphology of the testis.

Objective To investigate the hemorrhagic factors affecting the prognosis of patients with intracranial arteriovenous malformations (AVM)treated by microsurgery. Methods From January 2012 to March 2017,62 consecutive patients with hemorrhagic AVM who met the inclusion criteria and treated with microsurgery in the same vascular group at the Department of Neurosurgery,Tongji Hospital,Tongji Medical College,Huazhong University of Science and Technology were enrolled retrospectively. The patients were divided into either a good prognosis group (n =48,mRS≤2)or a poor prognosis group (n =14,mRS >2)according to the modified Rankin scale (mRS)scores during the follow up at 6 months after the operation. The general information of the patients were collected,including gender,age,history of primary hypertension, history of previous cerebral hemorrhage,Glasgow Coma Scale (GCS)score on admission,AVM location,size of AVM,type of AVM venous drainage,Spetzler-Martin grade,combined aneurysm,combined intraventricular hemorrhage,site of hemorrhage,and volume of hemorrhage. Univariate analysis and multivariate logistic regression analysis were used to analyze the hemorrhage-related factors affecting the prognosis of hemorrhagic AVM operation. Results (1)There were no significant differences in gender,age,history of primary hypertension,history of cerebral hemorrhage between the two groups (all P > 0. 05),and there was significant difference in GCS on admission (P < 0. 05). (2)Compared with the the good prognosis group,there were significant differences in functional area AVM (33. 3% [16 /48]vs. 12 /14),Spetzler- Martin grade ≤Ⅱ (85. 4% [41 /48]vs. 6 /14),volume of hemorrhage ≥30 ml (10. 4% [5 /48]vs. 8 /14), and intraventricular hemorrhage (8. 3% [4 /48]vs. 7 /14)in the poor prognosis group (all P < 0. 05). There were no significant difference in the AVM volume,type of venous drainage,combined aneurysm,and bleeding site between the two groups (all P >0. 05). (3)Multivariate logistic regression analysis was used to analyze the independent variables related to bleeding in univariate analysis,the results showed that intraventricular hemorrhage (OR,11. 000,95% CI 1. 722 -46. 231,P =0. 009)and volume of hemorrhage ≥30 ml (OR,11. 467,95% CI 2. 029 -44. 894,P = 0. 004)were the independent risk factors for poor prognosis. Conclusion The intraventricular hemorrhage and volume of hemorrhage ≥30 ml may be the independent risk factors affecting prognosis of patients of hemorrhagic AVM surgery,however,further validation is needed.
ABSTRACT
Objective To study the anatomic characteristics and clinical values of the internal auditory artery via the neuroendoscope and microscope.Methods We observed the related microdissection of the internal auditory artery of 15 cadavers through retrosigmoid approach by operative microscope and neuroendoscope,in which 3 cadavers were fresh.Results The internal auditory arteries were observed bilaterally in all specimens (100％).Among them,17 sides (56.7％,17/30) were isolated branch type,9 sides were dual trunk (30％,9/30),and 4 sides were three branches type (13.3％,4/30).The diameter of the vessel at its origin was 0.12～0.28 mm,the average caliber of IAA was 0.22±0.04 mm,the length of IAA ranged from 7.12 to 14.82 mm,and the Mean 10.18± 2.63 mm.The starting-point of IAA was quite variable,13.3％ (4/30) of the IAA origined from the inferior segment of the basilar artery,and 86.7 ％(26/30) of the IAA origined from ACIA.Among them,17 sides (65.4％,17/26) of the IAA origined from the ansa of the inferior cerebellar artery,9 sides (34.6％,9/26) of the IAA origined from the anterior inferior cerebellar artery involved in the inner ear canal.We observed that 73.3 ％(22/30) of the IAA branches were along the ventral side of the vestibulocochlear nerve;26.7 ％(8/30) of the IAA branches were above the nerves.It's easy to identify the IAA and its adjacent structures by various neuroendoscope through various anatomic fissures.Conclusion Most of internal auditory arterys were located anterior and posterior to the facial nerve,the microscope was impossible to see it directly.A thorough identification of the internal auditory artery requires theuse of both surgical microscopy and neuroendoscope.
ABSTRACT
The histopathological features of the middle cerebral artery (MCA) and superficial temporal artery (STA) from moyamoya disease (MMD) and their relationships with gender, age, angiography stage were explored. The causes and the clinical significance of vasculopathy of STA were also discussed. The clinical data and specimens of MCA and STA from 30 MMD patients were collected. Twelve samples of MCA and STA from non-MMD patients served as control group. Histopathological examination was then performed by measuring the thickness of intima and media, and statistical analysis was conducted. The MCA and STA specimens from MMD group had apparently thicker intima and thinner media than those from the control group. There was no significant pathological difference between the hemorrhage group and non-hemorrhage group, and between the males and females in MMD patients. Neither the age nor the digital subtraction angiography (DSA) stage was correlated with the thickness of intima in MCA and STA. MMD is a systemic vascular disease involving both intracranial and extracranial vessels. Preoperative external carotid arteriography, especially super-selective arteriography of the STA, benefits the selection of donor vessel.

Functional hemispherectomy can effectively control seizures and obviously improve the prognosis.
ABSTRACT
The purpose of this study was to evaluate the effect of adenosine A2A receptor antagonist ZM241385 on amygdala-kindled seizures and its roles in epileptogenesis. Electrodes were implanted into the right amygdala of male adult Wistar rats. Kindling was accomplished by using stimulus strength of 500 μA applied daily to the amygdala until 10 consecutive stage 5 seizues were induced. Then effect of ZM241385 was studied in fully kindled rats after intracerebroventricular administration of the drug. In addition, the effect on kindling progression was evaluated through ZM241385 injection before daily stimulation. In all experiments, behavioral changes in the rats in response to ZM241385 were monitored closely. The results showed that, in fully amygdala-kindled rats, ZM241385 (0.001-0.1 nmol/L) decreased afterdischage duration (ADD), motor seizure duration (MSD), stage 5 duration (S5D) and seizure duration (SD), but only the effect on ADD was dose-dependent. The doses of 0.001-0.1 nmol/L had no influence on stage 4 latency (S4L) and seizure stage (SS). The dosages of 0.0001 and 1 nmol/L of ZM241385 did not exert any effect on all seizure parameters. In contrast to the results in fully amygdala-kindled rats, ZM241385 (0.001-0.1 nmol/L) had minimal or no effects on the progression of amygdala-kindled seizures. We are led to the conclusion that although ZM241385 had no influence on the progression of amygdala-kindled seizures, it had potent anti-convulsant profile and little adverse effects at the dosage of 0.001-0.1 nmol/L, suggesting that the agent is effective against the amygdala-kindled seizures.
ABSTRACT
Clear cell hidradenocarcinoma (CCH) is an exceedingly rare and highly malignant tumor of the eccrine sweat glands. Its treatment is extremely difficult due to the characteristically aggressive clinical course including repeated local recurrence and uncontrollable distal metastasis coming along with a very poor prognosis. Most published case studies recommend a wide surgical excision followed by adjuvant conservative therapy, which is generally considered to be the standard treatment. Two cases of nodular CCH of the scalp either presenting as a singular primary lesion or at an already metastatic stage were analyzed retrospectively. Wide local excision of the tumor couldn't prevent the primary carcinoma from recurring and metastasizing. Both cases received various therapies but the results were unsatisfactory. Although most authors have recommended that early wide surgical excision of the tumor is a feasible therapeutic measurement, our results raise doubts on the efficacy of this treatment strategy. As alternative approaches (i.e. chemotherapy, radiotherapy) are similarly controversial, further studies and a wide exchange of clinical experiences are crucial.

ABSTRACT
Objective To evaluate retrospectively the role of 18 F-fluorodeoxyglucose (FDG) PET/CT associated with MRI in the localization of epileptogenic foci. Methods Sixty-seven patients with medically resistant epilepsy were included from 2003 to 2008. All underwent 18F-FDG PET/CT and MRI for presurgical evaluation as well as post-surgical evaluation 12 to 65 months after operation. Based on postoperative seizure occurrence, patients were divided into two groups. One group was free of seizures ( Engel classification Ⅰ, Group 1) and the other was with postoperative seizure occurrence of any type ( Engel classification Ⅱ-Ⅳ, Group 2). X2-test or Fisher's exact test was used for the statistical analysis. Results About 71.6% (48/67) patients were defined as group 1, and 19 patients were group 2 ( 11 were Engel Ⅱ , 5 were Engel Ⅲ, and 3 were Engel Ⅳ ). In Group 1, no statistically significant difference was found between concordant (45/63) and discordant findings (3/4) with regard to 18F-FDG PET/CT and MRI images (Fisher's exact test, P ＞0.05). For 41 patients that showed focal abnormality both on MRI and 18F-FDG PET/CT, 80.5% (33/41) were found in group 1. For 20 patients that showed focal lesions on MRI while with multi-focal or generalized abnormal metabolism on 18F-FDG PET/CT, 11 (55.0%) were in group 1 and9 (45.0%) were group 2. There was no significant difference (33/41 vs 11/20, X2 =4.34, P ＜0.05 ). Conclusion 18F-FDG PET/CT associated with MRI may offer more helpful information for pre-surgical evaluation and prediction of prognosis of epileptic patients.
