Objective To improve the operative outcome of parasagittal meningiomas in central area. Methods Twenty patients with parasagittal meningiomas were treated with microsurgery. Of them, 16 cases were taken DSA exzamination before operation to evaluate the blood supplies of the tumor, compensation of venus return around the tumor after obstruction of the sagittal sinus. During the operation, the parasagittal blood supplies were blocked first, the tumors were resected piece by piece. Rolandic veins, other compensative venous pathways and normal brains around the tumors were protected, and the involved sagittal sinuses were appropriately treated. Results Total removal of the tumor was reached in 17 cases, nearly total removal in 3 cases, no death. Postoperatively, 1 patient developed hemiparesis, 2 had paresis of both lower extremities. No tumor recurrence was found in 13 patients during the follow-up of 3～7 years. Conclusion Using microsurgical techniques in the resection of parasagittal meningioma in central area may improve the percentage of total tumor resection, decrease the injuries of important functional area of the brain, reduce complications and improve survival outcome.

To evaluate clinical effect of transcranial optic nerve decompression on fronto orbito sphenoidal fibrous dysplasia with progressive vision loss, 25 cases were studied retrospectively. All patients had undergone transcranial optic nerve decompression. One week after operation, 21 patients experienced improvement or stability in vision, but 4 patients complained reduction in vision. Before operation, the vision of the affected eye was near blindness in 3 cases among the 4 cases who failed to gain improvement in vision after operation. Effective follow up was achieved in 18 cases, and the follow up period was from two to twenty two years (average six years). Among them, only 3 paticnts showed recurrence of visual disturbance. The results showed that transcranial optic nerve decompression was effective in rescuing vision in fronto orbito sphenoidal fibrous dysplasia with progressive vision loss. Once the patient was near blind before the operation, the surgical result was unsatisfactory.

Objective To study the CT and MRI imaging features of central nervous system Rosai-Dorfman disease and to enhance knowledge and differential diagnostic ability for central nervous system Rosai-Dorfman disease.Methods The CT and MRI imaging appearances in 4 cases of pathologically proven Rosai-Dorfman disease were retrospectively evaluated and the literature of central nervous system Rosai-Dorfman disease were reviewed.Results Two cases had cranial CT scans,4 cases had cranial MRI scans,On CT scans,cerebral edema was demonstrated in one case and the other case was normaL MRI scans showed the lesions were solitary in saddle area in 3 cases,and multiple in anterior cranial fossa in 1 case.The lesions exhibited iso- to hypointensity on both T1WI and T2WI images.Following intravenous injection of contrast medium,ring-like enhancement was seen in 2 cases and homogeneous enhancement in 1 case.Nodular enhancement was seen in the case of multiple lesions in the anterior cranial fosse.All lesions were dural-based.Conclusions In patients with fever,headache,elevation of the erythrocyte sedimentation rate (ESR) and a polyclonal increase in .γ-globulins,the possibility of central nervous system Rosai-Dorfman disease should be considered when single or multiple dural-based mass lesions,especially in sellar region,were identified by CT and MRI.

OBJECTIVETo explore the mechanism and strategies of prevention and treatment of vision deterioration after transsphenoidal surgery for removal of pituitary adenoma.

METHODSFrom January 1980 to February 2001, 1 412 patients were operated on by transsphenoidal surgery to remove pituitary adenoma. Fourteen patients experienced vision deterioration after operation. Clinical data from the 14 patients with vision deterioration were analyzed retrospectively.

RESULTSIn this group, the incidence of vision deterioration was 0.99%. Over packing of the adenoma bed was seen in 5 patients, apoplexy of residual tumor in 3, high intracranial pressure in 2, vascular spasm in 2, injury of the optic nerve in the cannel in 1 and unknown reason in 1.

CONCLUSIONSVision deterioration is a severe complication after transsphenoidal surgery. Early diagnosis and treatment can greatly improve the vision.

Aim To investigate the effect of curcumin against high-fat-diet induced C57BL/6J mice bone changes and the correlation between the expression of cathepsin K and curcumin.Methods Curcumin treated C57BL/6J mice had been on high fat diet for 12 weeks.The HE, Alizarin red S staining and Safranin O/fast green staining of femur were employed to evaluate bone microstructure, bone metabolism and bone development.The expressions of cathepsin K were assessed by Western blot and immunohistochemical staining.Results Histopathological results showed that curcumin could improve the destruction of trabecular bone structure, cartilage development and bone calcification.Biomechanical results proved that curcumin could improve the bone strength of the type 2 diabetic mice induced by high fat.The results of immunohistochemistry and Western blot assay indicated that curcumin could significantly inhibit the expression of cathepsin K in bone tissues of mice.Conclusion Curcumin can increase bone strength, improve bone microstructure, and enhance the degree of bone calcification, which may be achieved by inhibiting the expression of cathepsin K.

Objective To investigate the indications of optic canal decompression in the patients with front-orbital fibrous dysplasia and the methods of intraoperative optic canal localization and decompression. Methods We collected 30 cases of fibrous dysplasia. All patients had sufficient images assessment. Patients with symptoms underwent surgery, including front-orbital cranioplasty and optic canal decompression. The frontotemporal epidural approaches were used. If there was a proptosis, the approach was extended with the removal of superior orbital ridge. Six patients undertook intraoperative CT and MRI fusion navigation, assisting in confirming the trunk, orbital and cranial orifice of optic nerve. During the operation, the optic canals were decompressed by three-bits method, to confirm the position of optic nerve. Results There were 30 cases of optic canal decompression and one case of vision loss. The visual acuity and vision field of the remaining patients improved to varying degrees. The proptosis disappeared or alleviated after the operation. Thirteen cases were reconstructed with normal internal plate, five cases with titanium plate, nine cases without reconstruction, and two cases were paved with proliferative broken bone on the orbital top; one case recurred with exophthalmos again after five years, but the visual acuity did not decline. Conclusion For the patients with front-orbital fibrous dysplasia, active surgical treatment should be taken, optic canal decompression should be chosen for diminution of vision, craniofacial anaplasty and orbital decompression should be performed in patients with facial deformity. The epidural approach is a good option to locate the optic nerve from the orbital orifice or cranial orifice. Combined with the three-bits method, we can achieve safe and meticulous optic nerve decompression.

Objective : To study the correlation between short stature and ocular biological parameters in children. Methods : This study adopted a cross⁃sectional study. Eighty⁃two children (82 eyes) with height lower than the tenth percentage and normal vision were selected as the short group. One hundred and thirty healthy children ( 130 eyes) with age and sex matching were served as the control group. Ocular biological parameters were measured for all subjects , including visual acuity , axial length , corneal curvature , astigmatism , intraocular pressure , central corneal thickness , anterior chamber depth , lens thickness and the distance of whiteness to whiteness. Then axial length/corneal radius ratio was calculated. The differences in ocular biological parameters between the two groups and the correlation between height and parameters were analyzed. Results: The measurement of ocular biological parameters showed that the axial length of the short group was lower than that of the control group , and the difference was statistically significant( t = - 3. 161 ,P = 0. 002) . Also there were significant differences in corneal curvature , anterior chamber depth between the two groups ( t = 2. 996 , - 2. 449, P < 0. 05) . The corneal curvature of the short group was greater than that of the control group , and the anterior chamber depth of the short group was smaller than that of the control group. There were no significant differences in other ocular biological parameters ( P >0. 05) . Conclusion There are differences between ocular biological parameters in short children and healthy children ,which suggests that on the one hand , parents should pay attention to the development of the eyes of their children as soon as possible ; On the other hand , there should be different screening standards for short children in eye screening. Moreover, more comprehensive studies need to be included to supplement this data in the future.

Objective: To evaluate the effect of inactivated SARS-CoV-2 vaccine on the clinical outcomes of patients infected with the Omicron variant. Methods: A total of 1 403 Omicron-infected patients admitted to 20 designated hospitals in Guangdong Province from January 1 to May 31, 2022, were selected as subjects in this study. A case-control study was conducted to collect the demographic data, underlying disease, vaccination status, last exposure date, gene sequencing of infected strains and clinical outcomes from the China Disease Prevention and Control Information System and Guangdong telemedicine platform. Pneumonia (common, severe and critical) and non-pneumonia (asymptomatic and mild) were selected as the case group and control group. The effect of inactivated SARS-CoV-2 vaccine on the clinical outcomes of patients infected with the Omicron variant was analyzed. Results: The median age [M (Q₁, Q₃)] of the subjects was 36 (27-47) years old, with males accounting for 52.25% (733 cases). The main outcome of the infection was non-pneumonia, accounting for 92.09% (1 292 cases), and the duration [M (Q₁, Q₃)] of the disease was 18 (14-22) days. There were 134 (9.55%), 39 (2.78%), 403 (28.72%), 437 (31.15%) and 390 (27.80%) cases with no or partial vaccination, within 90 days of primary vaccination, over 90 days of primary vaccination, within 90 days of booster vaccination and over 90 days of booster vaccination, respectively. Multivariate logistic regression analysis showed that after adjusting for gender, age, underlying disease, and location of the report, compared with those with no or partial vaccination, the risk of developing pneumonia was lower in those with over 90 days of primary vaccination, within 90 days of booster vaccination and over 90 days of booster vaccination [OR (95%CI) values were 0.52 (0.28-0.98), 0.39 (0.21-0.73) and 0.40 (0.21-0.77), respectively]. Cox proportional hazard regression model analysis showed that after adjusting for gender, age, underlying disease and location of the report, the duration of the disease was shorter in those who received booster vaccinated for more than 90 days compared with that in those who had no or partial vaccination [HR (95%CI): 1.26 (1.03-1.55)]. Conclusion: The inactivated SARS-CoV-2 vaccine affects the clinical outcomes of patients infected with the Omicron variant.
