The thoracic ossification of the ligamentum flavum(OLF)is usually located in the lower thoracic spine.Thoracic OLF has been widely recognized as a main cause of thoracic myelopathy.The pathogenesis of OLF is poorly understood.Because the thoracic OLF has many clinical manifestations and it is commonly combined with other spinal disorders,it is easy to be misdiagnosed or to be a delayed diagnosis.The surgical treatment of thoracic OLF has high risk and Serious complications.In this paper the pathogenesis,diagnosis and treatment of thoracic ossification of ligamentum flavum in recent years are reviewed.

ObjectiveTo study the clinical characteristics of the temperature instability in Prader-Willi syndrome (PWS). MethodsThe clinical characteristics of one case of PWS with recurrent fever were retrospectively analyzed.ResultsA 5-month-old boy who had such clinical characteristics as low central muscle tension, sucking weakness, feeding dififculties, cryptorchidism and white skin was diagnosed as PWS by chromosomal microarray analysis and methylation-speciifc PCR. In the course of the disease, the infant presented recurrent fever. The pathogenic bacteria culture and virus antibody detection showed negative, and the treatment of reducing fever, anti-infection and immune support were ineffective.ConclusionsThe cause of the recurrent fever is unknown and central fever is suspected. Whether the temperature instability is the clinical feature of PWS still needs a lot of clinical researches.

Objective To investigate the causes and characterization of hepatic encephalopathy after transjugular intrahepatic portosystemic shunts(TIPSS).Methods 32 cases of patients with recepted TIPSS operation were enrolled in retrospective study.Results 9 of 32 patients suffered from hepatic encephalopathy were detected out after TIPSS. The present of hepatic encephalopathy was associated with the flow direction of blood in portvein after the operation(P

Asthma is one kind of chronic respiratory tract inflammatory disease.Recently,it has been discovered that the small airway also participates in asthmatic pathogenesis.The small airway which diameter is less than 2 mm is one of the smallest regions in the lung.Its function may be affected by the small airway disease and related with the airway hyperresponsiveness.Some structural changes in the small airway is the latent reason which aggravates asthma.The change of small airway function in the mild asthma can cause the change of airway hyperresponsiveness.So it is considered that the small airway function is one of the methods to monitor the asthmatic situation.

Objective:To observe the clinic effectiveness of cryoretinopexy under light fiber illumination during vitreoretinal surgery. Methods: Twenty-two patients with complex retinal detachment underwent vitrectomy,fluid-air exchange,cryoretinopexy under light fiber illumination.Postoperative vitreous cavity tamponade was accomplished with silicone oil in 14 cases,perfluoropropane gas in 8 cases,8 cases combined with sclera encircling. Results: Postoperative follow-up ranged 3 months to 1 year,retinal tear or hole closed and retina reattached in 20 cases.The success rate of operation was 90.9%. Conclusion: Cryoretinopexy under light fiber illumination during vitreoretinal surgery positioning is easy and accurate and the effect is definite.

Objective To establish an HPLC method to determine the content of diosgenin in Paridis Rhizoma; To examine contents of diosgenin in different varieties of Paridis Rhizoma medicinal plants and from different habitats. Methods Shimadzu Inertsil ODS-C18 guard column (150 mm×4.6 mm, 5μm) was used in HPLC system; elution conditions were the mobile phase using 92% acetonitrile and 8% water (isocraticelution) at a flow rate of 1.0 mL/min with 203 nm detection wavelength. The temperature of the column oven was maintained at 30℃.Results Different varieties of Paridis Rhizoma medicinal plants and Paridis Rhizoma medicinal plants from different habitats contained diosgenin. TheParis polyphylla var.pseudothibetica in Yubei district had the highest content (6.813 7 mg/g);Paris polyphylla var.stenophylla in Chengkou County had the middle content (5.758 4 mg/g);Paris yunnanensisFranch in Shizhu county showed the lowest content (1.952 2 mg/g). The results showed that the obvious difference of chemical quality between various cultivated varieties of Paridis Rhizoma medicinal plants, which might be related with origin, variety and the cultivation technology, and so on.Conclusion The diosgenin contents ofParis polyphylla var. pseudothibetica andParis polyphylla var.stenophylla were higher than that of varieties recorded in Chinese Pharmacopeia.Paris polyphylla var.pseudothibetica andParis polyphylla var.stenophylla had important medical value.

Objective To discuss the management of solid-pseudopapillary tumor of the pancreas. Methods Four patients of solid-pseudopapillary tumor of the pancreas (SPT) were diagnosed by pathology. One patient was underwent magnetic resonance and two enhanced computer tomography scan. The mass was located in tuberculum (1 case), neck (1 case), and body-tail (2 cases) of pancreases respectively. Four cases were underwent duodenopancreatectomy, local resection of mass, resection of body-tail of pancreases respectively. The maximal diameter of tumor ranged from 5 cm to 16cm, averaged 10.3cm. The blood regular test and biochemistry were normal, and the tumor markers including AFP,CA19-9,CA125,CEA also were normal. The specimens were examined by pathology and immunohistochemistry. Results Four cases all were diagnosed solid-pseudopapillary tumor of the pancreas by pathology. At histologic analysis, the tumor was composed of uniform polygonal cells with moderate to abundant amphophilic cytoplasm and arranged in solid nests with areas of degeneration characterized by separation of the cells into pseudopapillary aggregates with intervening accumulation of mucopolysaccharide rich ground substance. The expressions of Vimentin, α-ACT, α-AAT were positive, and CgA negative. Four cases were followed up for six months and norecurred. Conclusions SPT of pancreases was a kind of tumor of low potential malignancy, and the magnetic resonance and computer tomography were often to be used. The effective therapy was thoroughly resection, and the prognosis in most patients is excellent.

Objective To detect kinematics and surface electromyography (sEMG) of upper limbs in normal children and motor-delayed children for clinical assessment. Methods From December, 2015 to June, 2016, twelve healthy children and thirteen children with motor de-velopmental delay less than two years old were analyzed kinematics with Motion Analysis system and sEMG. Results The angle of motion of right shoulder was more in the motor-delayed children than in the normal children (t=2.576, P<0.05). The difference of root mean square values of bilateral triceps brachii was more in the motor-delayed children than in the normal ones (t=2.448, P<0.05). Conclusion Detecting kinematics and sEMG may supply information for early personalized treatment strategy.
