Objective To investigate the clinical characteristics,diagnosis and treatment of invasive pituitary adenoma.Methods The clinical presentations,imaging studies and surgical outcomes in 62 patients with invasive pituitary adenomas and 78 patients with noninvasive pituitary adenomas were analyzed retrospectively.Results Invasive pituitary adenomas were more common in patients with macroadenomas than those with microadenomas(P

Objective To explore the microsurgical technique in managing medial sphenoid ridge meningioma.Methods The clinical data of 23 cases of medial sphenoidal ridge meningioma were analyzed retrospectively.The main points of microsurgical treatment of medial sphenoid ridge meningioma were discussed.Results Of 23 cases of medial sphenoid ridge meningiomas,total removal was made in 15 cases,subtotal removal in 6 cases and partial removal in 2 cases.The microsurgical outcomes were satisfactory in all the patients and no patients died.Conclusion The microsurgery via the pterional approach to the medial sphenoid ridge meningiomas can greatly heighten total resection rate of the tumors.Total resection of the tumor depends on its position,character and degree of edema of surrounding tissues.Palliative operations combined with postoperative radiotherapy should be carried out for treating the tumors that can only be subtotally and partially removed.

To analyze amino acid and fatty acid of Fructus Broussonetiae . The amino acids of Fructus Broussonetiae were analyzed with automatic amino acid instrument and fatty acids were analyzed with GC MS Computer system. More than 14 amino acids were analyzed and the fatty acid from Fructus Broussonetiae contains 17 compounds, of which 8,11 octadecadienoic acid and Hexadecanoic acid are main components.The abundance of amino acids and unsaturated fatty acid may contribute to the tonic function of Fructus Broussonetiae .

Objective To explore the efficiency,safety and suitable dosage of the non-invasive treatment of malignant gliomas with high intensity focused ultrasound(HIFU).Methods An extracorporeal HIFU with 9.7 MHz transducer(focal length: 4.5 mm,focal intensity: 2 500 W/cm~(2)) was used.Fifteen resected human malignant gliomas were randomly assigned to receive HIFU ablation for 10,20,30 s.After the treatment,the exposure coverage and marginal zone were collected and examined by HE staining and electron microscope.Results Exposure coverage and margin was safe in 10 s group.Typical coagulation necrosis was detected at exposure coverage with no detectable change at margin in 20 s group.Typical coagulation necrosis was seen at both exposure coverage and margin in 30 s group.Conclusion Under the parameters used in this study,20 s is a beneficial therapeutic dosage.HIFU is an accurate method for malignant gliomas ablation.

Objective To investigate the effects of seed sources and storage conditions on the seed germination rate of Valeriana officinalis. Methods The seeds of V. officinalis under different storage conditions were used as materials for germination test, and the germination rate was calculated and compared according to the results. Results The seed germination rate of valerians is varied with different sources. The seed germination rate of V. officinalis is higher than that of V. officinalis var. latifolia, and the seed germination rate of cultivated valeriana is much higher than that of the wild plant. The storage periods, storage temperature, and germination conditions also affect the germination rate. Conclusion To maintain the seed germination rate, the seed of V. officinalis should be stored in conditions with ventilation and at suitable low temperature. Lower temperature helps to prolong the seed life with relatively high germination rate. Valeriana seed should also be propagated at available temperature conditions in proper seasons.

Objective To explore the relationship between mRNA and protein expressions of PTTG, bFGF, P53 with tumorigenesis and invasiveness of pituitary adenoma. Methods The protein expressions of PTTG, bFGF, P53 were detected by immunohistochemical analysis, and their mRNA expressions were by reverse transcription polymerase chain reaction (RT-PCR) in 63 specimens of pituitary adenoma that was classified into invasive and non-invasive according to Wilson’s modified staging. Results Thirty-four specimens of pituitary adenoma were invasive and 29 non-invasive. The expressions of PTTG, bFGF, P53 were significantly higher in invasive pituitary adenoma than in non-invasive. The analysis of correlation showed that in invasive pituitary adenoma, the positive correlation exists between PTTG and bFGF mRNA (r=0.81, P

Objective To investigate expression changes of Tau protein in retinal ganglion cells (RGCs) and oligodendrocytes (Ols) after stretch injury in rats and explore the relationship of Tau protein with pathological changes after axonal injury. Methods Morphological changes of optic nerves, RGCs and OLs after stretch injury were examined under light microscope in control group, stretch only group, heat stress only group and heat stress pretreatment plus stretch group. The expressions of Tau protein in RGCs and OLs after heat stress and/or stretch injury were observed by using immunohistechemical stai-ning. Results Pathological changes of axons, RGCs and OLs were identified morphologically or quan-titatively after stretch injury to the optic nerves, which was significantly ameliorated through pretreatment with heat stress plus stretch injury. The expressions of Tau protein in RGCs and OLs were increased in stretch only group. There was no significant expression change of Tau protein in heat stress only group. Expression of Tan protein was obviously decreased in heat stress pretreatment plus stretch group. Con-clusions Both neurons and glial cells are involved in pathological process after axonal injury. The ex-pression changes of Tau protein are probably related to delayed axotomy and neuron apoptosis. Heat stress can relieve the impairment of cystoskeleton through decreasing and delaying the expression of Tau protein.

With the continuous improvement of treatment ability in intensive care unit (ICU), many critically ill and complex patients have survived due to the development of technology. However, most of them suffer from the psychological and physiological problems of post-intensive care syndrome (PICS). Therefore, the early identification and prevention of PICS is particularly critical. We should understand the pathophysiological mechanism of PICS, strictly implement ABCDEFG bundle management measures [including airway management (A), breath (B), reasonable analgesia and sedation treatment (C), prevention of delirium (D), early rehabilitation (E), family engagement (F), good communication (G)] during ICU hospitalization, and pay attention to reasonable nutritional support, optimizing blood glucose management, providing positive psychological intervention and support to patients through family members' encouragement and accompanying, ICU diary and other forms, following up the health status of patients transferred out/discharged from ICU, providing multi-disciplinary and professional continuing medical services, finding the entry point and timing of traditional Chinese medicine intervention, and giving full play to the advantages of integrated traditional Chinese and Western medicine treatment, which can improve the quality of life of patients. This article reviews the pathophysiological mechanism, risk factors, prevention and management measures, traditional Chinese medicine syndrome differentiation and treatment of PICS, in order to improve the early identification, diagnosis and treatment of critical patients with PICS, and improve the prognosis of patients.

ObjectiveTo investigate the semantic induce effects in reading disorder of the Chinese deep dyslexia. MethodsA patient with deep dyslexia was researched with initials inducement (as phonetic inducement), semantic-related words inducement, numeral inducement, quantifier inducement, context inducement and actual object inducement (all as semantic inducement). ResultsThe rate of correct results were more with semantic inducements than with phonetic inducement (91.30%, 76.67%, 94.44%, 83.33% vs 44.44%, P<0.001). ConclusionThe semantic induce training is more effective than the phonetic induce training on Chinese deep dyslexia.
