Abstract
Objective: To evaluate the improvement of papilledema and visual acuities in patients with idiopathic intracranial hypertension (IIH) after venous sinus stenting. Methods: The clinical data of 8 IIH patients who met the inclusion criteria underwent venous sinus stenting between January 2013 and December 2016 at Department of Neurosurgery, Tianjin Huanhu Hospital were analyzed retrospectively. There were 6 females and 3 males,aged (32.9±14.4)years (range:19 to 57 years).The thickness of the retinal nerve fiber layer (RNFL) was measured by optical coherence tomography. Fundus,visual acuity and visual field examination were performed before and after operation. If pressure gradient ≥10 mmHg(1 mmHg=0.133 kPa) across the venous stenosis was indicated by intraoperative pressure measurement,the patient would be treated with venous sinus stenting. Intracranial pressure was measured by lumbar puncture 3 to 7 days after operation. RNFL thickness and eye examination were detected 6 months after surgery. CT venogram was used to observe the sinus venous conditions. Paired t test was used to compare the data before and after surgery. Results: All the 8 patients underwent venous sinus stenting successfully. The mean pressure gradient across the venous stenosis was reduced from (24±9.2) mmHg to (2.6±2.0) mmHg (t=8.02,P<0.01). Intracranial pressure decreased from preoperative (41.4±12.7) cmH2O(1 cmH2O=0.098 kPa) to postoperative (12.9±3.3) cmH2O (t=7.08, P<0.01). The RNFL thickness decreased from (275.3±68.3)μm to (131.4±31.8)μm(t=5.80,P<0.05) 6 months after surgery and the baseline visual acuity was improved from(M(QR))0.24 (0.25) to 0.65 (0.23)(Z=-2.52,P<0.05).Papilledema was significantly improved in 6 patients,and no significant change in 2 patients. CT venogram indicated adjacent stent restenosis in 1 patient. Conclusion: Venous sinus stenting can effectively improve papilledema and visual acuity caused by IIH.

Abstract
Objective: To evaluate the application of combination use of endoscopic endonasal approach combined with the frontotemporal orbitozygomatic approach microscopically in skull base tumor with intra and extra-cranial involvement. Methods: A total of 7 patients (4 males and 3 females, aging from 27 to 65 years old, with a medium age of 48) undergone complicated skull base surgeries via endoscopic endonasal approach combined with the frontotemporal orbitozygomatic approach microscopically from May 2016 to January 2018 were reviewed respectively. The patients included 2 cases of recurrent invasive pituitary adenoma, 3 cases of basal skull meningiomas, 1 case of clivus chondrosarcoma, and 1 case of recurrent nasopharyngeal carcinoma. The lesion extensively infiltrated nasal cavity, extending to the paranasal sinus, bilateral cavernous sinus, sellar region, suprasellar, superior clivus, temporal lobe, pterygopalatine fossa, infratemporal fossa and important intracranial vessels. All the 7 patients were treated under general anesthesia by endoscopic endonasal approach combined with frontotemporal orbitozygomatic approach under the microscope. Total excision rate, intraoperative and postoperative complications and postoperative curative effect were observed. All of them were followed up for 6 to 12 months. The Glasgow Outcome Scale (GOS) was used to evaluate the prognosis. Result: Total tumor removal was performed in 5 cases, subtotal removel in 2 cases. There was no complication during the operation. Postoperative severe complications occurred in 2 cases, including 1 case of cerebrospinal fluid rhinorrhea and intracranial infection, which was cured by lumbar cistern drainage and intrathecal injection; 1 case occurred oculomotor nerve paralysis, which recovered during follow-up. Postoperative complications occurred in 1 case of trochlear nerve dysfunction, 2 cases of facial numbness, and 1 case of tinnitus. During follow-up, all patients recovered to varying degrees. There was no bleeding and death after the operation. No tumor recurred during the follow-up period. All patients were recovered well with GOS grade Ⅳ-Ⅴ. Conclusions: Endoscopic transnasal approach combined with microscopic frontotemporal orbitozygomatic approach can remove tumors in one stage, reduce surgical complications and improve surgical effect. It has good application prospects and is suitable for excising complex intracranial and extracranial communicating tumors of widely involving sellar, clivus and petrous apex area.

Long-term combined chemical and manure fertilizations increase soil organic carbon and total nitrogen in aggregate fractions at three typical cropland soils in China.

Abstract
Soil organic carbon (SOC), total nitrogen (TN), microbial biomass carbon (MBC) and nitrogen (MBN) are important factors of soil fertility. However, effects of the combined chemical fertilizer and organic manure or straw on these factors and their relationships are less addressed under long-term fertilizations. This study addressed changes in SOC, TN, MBC and MBN at 0-20 cm soil depth under three 17 years (September 1990-September 2007) long-term fertilization croplands along a heat and water gradient in China. Four soil physical fractions (coarse free and fine free particulate organic C, cfPOC and ffPOC; intra-microaggregate POC, iPOC; and mineral associated organic C, MOC) were examined under five fertilizations: unfertilized control, chemical nitrogen (N), phosphorus (P) and potassium (K) (NPK), NPK plus straw (NPKS, hereafter straw return), and NPK plus manure (NPKM and 1.5NPKM, hereafter manure). Compared with Control, manure significantly increased all tested parameters. SOC and TN in fractions distributed as MOC > iPOC > cfPOC > ffPOC with the highest increase in cfPOC (329.3%) and cfPTN (431.1%), and the lowest in MOC (40.8%) and MTN (45.4%) under manure. SOC significantly positively correlated with MBC, cfPOC, ffPOC, iPOC and MOC (R(2) = 0.51-0.84, P < 0.01), while TN with cfPTN, ffPTN, iPTN and MTN (R(2) = 0.45-0.79, P < 0.01), but not with MBN, respectively. Principal component analyses explained 86.9-91.2% variance of SOC, TN, MBC, MBN, SOC and TN in each fraction. Our results demonstrated that cfPOC was a sensitive SOC indicator and manure addition was the best fertilization for improving soil fertility while straw return should take into account climate factors in Chinese croplands.
