ObjectiveTo determine the effectiveness of endovascular embolization in patients with cryptogenic massive hemoptysis who were all long-term smokers.Methods Aortography and subclavian artery angiography were performed in 21long-term smokers with cryptogenicmassive hemoptysis.Transarterial embolization (TAE) was performed in patients with detectable pathologic systemic arteries.The angiographic findings were reviewed and the clinical and follow-up CT results were observed.ResultsThe pathologic systemic arteries were all bronchial arteries (BAs) and thirty-five arteries were involved.The angiography demonstrated peripheral hyperplasia in all BAs,with 24 pathologic BAs supplying the right lung and 25 supplying the upper lobes.In thirty-five BAs,24 showed hypertrophy and 11 were normal.TAE of the pathologic BAs was successfully performed and cessation of bleeding was achieved in all patients.During follow-up,one patient had episodic bloody sputum after embolization and no recurrence in all patients.The follow-up CTdemonstratednoadditionalabnormalitybesidespre-existingpulmonaryemphysema.Conclusion Cryptogenic massive hemoptysis in long-term smokers efficiently treated by endovascular embolization of the responsible bronchial artery.

Objective To determine the effectiveness of endovascular embolization through pulmonary artery access in patients with refractory massive hemoptysis in whom systemic artery (SA)embolization is ineffective or contraindicated. Methods A total of 102 patients were treated with SA embolization for hemoptysis. Of the 102 patients, 6 patients had severe persistent hemoptysis despite complete SA embolization and 1 patient had severe hemoptysis following complete bronchial artery embolization and other SA embolization was contraindicated. The underlying diseases were chronic cavitary pulmonary tuberculosis (n = 3), chronic cavitary pulmonary tuberculosis complicated with aspergilloma (n=1), tuberculous bronchiectasis (n=1), severe necrotizing pneumonia (n=1) and bronchiectasis complicated with pneumatocele (n=1). The findings of SA angiography, main pulmonary angiography and selective pulmonary angiography were analyzed. Endovascular embolization was performed in patients with the detectable pathology in PA and the clinical results were observed. Results The findings of SA angiography showed bronchopulmonary shunting in all cases, and pseudoaneurysm of PA in 2 cases and hypertrophy of peripheral PA in 2 cases. The main PA angiography demonstrated pseudoaneurysm of PA in 1 case and hypoperfusion of the diseased PA in other case. The selective PA angiography demonstrated pseudoaneurysm of PA in 4 cases (1 case with extravasation of constrast medium) and hypertrophy ofperipheral PA in 2 cases. Coil embolizations of the pathologic PA were successfully performed and bleeding ceased in all patients. During follow-up, 1 patient had episodic bloody sputum after embolization, and 2 died day 6 and 15 of severe infection and respiratory failure and the remaining patients were all stable.Conclusions In patients with refractory massive hemoptysis after systemic embolization, the possibility of PA pathology, especially pseudoaneurysm of PA should be considered. Selective pulmonary angiography is necessary to demonstrate the pathology in PA. Endovascular management of the pathologic PA appears to be a safe and effective treatment.

Objective To investigate the feasibility and effectiveness of fast track surgery (FTS) in neurosurgery. Methods One hundred fifteen patients who underwent neurosurgery surgery in Henan Province People's Hospital from June 2012 to March 2014 were enrolled in this study. All the patients were divided into FTS group (62 cases) and the tra?ditional operation group (53 cases). The clinical index, postoperative hospital stay and hospitalization cost were compared between the two groups. Results The clinical index were significantly lower in FTS group than in traditional operation group (P<0.05). Length of hospital stay (days) and hospitalization cost of FTS group were significantly shorter and lower in FTS group compared with traditonal operation group (8±1 vs. 11±2 days and RMB 4.58 ±0.75 vs. 5.78 ±0.64 ten thou?sand, respectively) (P<0.05). Conclusion FTS in neurosurgery operation is an all-new concept for surgery which can ef?fectively reduce postoperative complications, shorten length of hospital stay, decrease hospitalization cost and promote postoperative recovery.

31 patients with cysticercosis of cerebral ventricles verified by operation or pathological investigation were reported. All patients were between 7 and 64 years of age and 14 were females. All had a single cyst. Since 29 patients (94%) were without a history of intestinal taeniasis, it was proposed that most patients of cysticercosis of cerebral ventricles were caused by hetero-infection and the entrance of Cysticercus into brain ventricle was through choroid plexus along the cerebro-spinal fluid. This is probably the reason why it occurs mostly in the 4th ventricle. The clinical manifestation of cysticercosis of cerebral ventricles were paroxysmal headache and vomiting caused by increased intracranial pressure. Ventricu-lography and CT scanning have considerable diagnostic value. Removal of Cysticercus by surgical operation is successful (Figs. 1 - 8).

BACKGROUNDTo evaluate the relationship among indoor air pollution, depression and oncogenesis of lung cancer.

METHODSAn 1:3 matched case-control study was carried out. Conditional logistic regression was applied to process the data.

RESULTSAfter some confounding factors were adjusted, the ORs increased 122% and 113% for the amount of coal using ≥46kg/m² and heating by coal stove respectively. The ORs elevated more than five-folds for disharmony and rupture of marriage, difference of accommodation and acclimation by oneself and human relationship respectively. The risk of lung caner obviously increased for frequent exposure to indoor cooking smoke combinated with depressed mood or mental scar respectively.

CONCLUSIONSThe indoor air pollution, depression and mental scar are important factors of oncogenesis of lung cancer.

Objective To explore the effectiveness of early lumbar pool drainage combined with antibiotics treatment in remedying ventricle peritoneal shunt infection and the problems needed to be paid attention during the process of treatment.Methods Twenty-two patients with infection after ventricle peritoneal shunt,admitted to our hospital from January 2008 to June 2015,were given lumbar pool drainage combined with antibiotics treatment,including 16 with early lumbar pool drainage combined with antibiotics treatment (3-7 d of infection) and 6 with late lumbar pool drainage combined with antibiotics treatment (8-10 d of infection).The clinical data and treatment efficacy were retrospectively analyzed.Results Bacterial culture of cerebrospinal fluid in the 22 patients indicated negative results in 5,coagulase negative staphylococcus in 10,staphylococcus aureus in two,enterococcus in two and klebsiella bacillus in three;the cure rate of patients with staphylococcus aureus was the lowest (0％);after lumbar pool drainage combined with antibiotics treatment,the cure rate of these patients reached to 72.7％ (16/22);the infection of the left 6 patients could not be controlled,and therefore ventriculoperitoneal shunt was removed.The cure rate in patients with early treatment was better than that in patients with late treatment (88％ vs.33％).Conclusion Early lumbar drainage combined with antibiotics can effectively control the ventricle peritoneal shunt infection,avoid risk of second operation and save economic burden.

Objective To discuss the strategies and efficacies of surgical treatment in medulla oblongata cavernous malformations.Methods The clinical and follow-up data of 9 patients with medulla oblongata cavernous malformations,admitted to our hospital from October 201 1 to February 2015,were retrospectively analyzed.Five patients underwent surgical treatment:posterior midline transcerebellomedullary fissure approach was used in 4,far-lateral transcondylar approach in one,and all cavernous malformations were excised completely.Conservative treatment and regular observation were done in 4 patients.Follow-up was performed for 10-40 months.Results Symptoms improved after surgery in 4 patients;postoperative hemiplegia appeared in one,and at the end of follow-up,the muscle strength of hemiplegic limbs recovered to level Ⅳ.Minor re-hemorrhage was noted in one of the 4 patients with conservative treatment at the end of the follow-up,and no changes were noted in the rest patients.Karnofsky Performance Scale scores were 82.2 ±6.7,which were significantly increased as compared with those before treatment (73.3±11.2,P＜0.05).Conclusion After strict preoperative evaluation,surgical treatment is a feasible way,enjoying good prognosis in medulla oblongata cavernous malformations;but,patients with deep site,small malformations or no obvious bleeding symptoms should not be operated.

Objective To explore the clinical efficacy of simple frameless stereotactic ventricle peritoneal shunt.Methods Retrospective analysis was performed in 128 patients with hydrocephalus,admitted to and performed ventriculoperitoneal shunt in our hospital from March 2012 to March 2016:simple frameless stereotactic ventricle peritoneal shunt was performed in 47,traditional occipital horn puncture in 23,and traditional triangle puncture in 58.The respective end of shunt tube placement position and recent end shunt tube adjustment were analyzed retrospectively.Results Inappropriate position was achieved in one patient performed simple frameless stereotactic biopsy,and no recent change or reset the shunt pipe was performed.In patients accepted traditional pillow angle puncture,head end improper placement happened in 5 patients,adjustment of recent tip was performed in 3.In patients accepted traditional triangle puncture,incorrect triangle needle tip was placed in 20 patients,and recent change or reset the head end shunt was performed in 7.Conclusion Simple frameless stereotactic puncture is effective in shunt placement of head end,which can lower the head end shunt recent change or reset the risk.

Objective To analyze the clinical and electrophysiological features in a family with spinal muscular atrophy (SMA), and assess the probable causative gene mutations for the family. Methods To identify the nosogenesis of the proband with weakness and atrophy in the double lower proximal limbs, clinical data of his 12 family members were collected, and the proband and his mother were selected for clinical examinations, including laboratory tests, electromyogram (EMG), F-wave, H-reflex, X-ray of the spine and double lower limbs, brain and spinal cord magnetic resonance imaging, etc. Moreover, human whole exome sequencing was performed on blood sample from the proband, then its deleterious effects were assessed according to the Standards and guidelines for the interpretation of sequence variants, a joint consensus recommendation of the American College of Medical Genomics (ACMG) and the Association for Molecular Pathology (AMP). Subsequently, the strong pathogenic mutation was validated by Sanger sequencing. Results Familial investigation showed seven of 12 family members presented with weakness in the double lower proximal limbs. Among them, three had the main manifestation of atrophy in the double lower proximal limbs, one had high arched foot as the main presentation, and the others had weakness in the double lower proximal limbs. EMG studies showed the abnormal results in the anterior horn of the spinal cord. The strong pathogenic mutation in DYNC1H1 gene (exon8, c.2327C＞T, p.P776L) was identified from the proband according to ACMG and AMP guidelines. Sanger sequencing revealed six patients had this variant and it was passed mainly from his maternal grandmother. Conclusions A pathogenic mutation of the DYNC1H1 p.P776L in six Chinese pedigrees which cosegregated with SMA was identified. There existed individual differences in clinical presentations. This finding may have important implications for the study of SMA in Chinese patients.
