Objective 　To evaluate the quantitative sensory testing in Guillain-Barre syndrome (GBS) and polyneuropathy (PNP). Methods　The quantitative sensory test (QST) was performed with Thermal Sensory Analyzer(TSA-2001) and Vibratory Sensory Analyzer(VSA-6003). Thermal and vibratory sensory tests were performed in the left patients with GBS or PNP and healthy subjects, on four sites of the left limbs by the method of Limits. Stimultaneously sensory conduction velocity (SCV) was measured. Results　There were increased TT and VT on distal limbs in the patients with GBS (with or without the symptoms or signs of disturbance of sensation) and PNP. QST in GBS and PNP was more sensitive than the clinical examination and SCV. There was significant association between VT and SCV in GBS, but not a significant association between TT\, VT and SCV in PNP. There was a paradoxical heat sensation in two patients with uremic PNP. Conclusions　QST is a sensitive and reliable test and can be a useful test in the diagnosis of PNP.

Adenoid cystic carcinoma(ACC) of the salivary gland constitutes approximately 21.9%-24.0% of all salivary gland malignant tumors,and is described as a tumor with indolent,but persistent and recurrent,growth and late onset of metastases,leading eventually to death.This review focuses on the advances in the studies of the diagnosis,treatment,and prognosis of ACC in the recent years.

Objective To evaluate the application of quantitative sensory testing (QST) to diabetic peripheral neuropathy. Methods TSA 2001 thermal sensory analyzer and VSA 6003 vibratory sensory analyzer made in Israel were used for thermal, vibratory tests and sensory conduction velocity (SCV) at four different locations of extremities in 45 diabetics and 22 normal persons. Results The thermal threshold (TT) and vibratory threshold (VT) of the diabetics were higher than those of age matched normal controls. In diabetics the TT was more frequently abnormal than the VT, which suggested that the small nerve fibers were more vulnerable than large fibers. Quantitative thermal testing (QTT) was more sensitive than quantitative vibratory testing (QVT) and SCV in diabetic peripheral neuropathy, especially in subclinical neuropathy. There was no significant correlation between the TT or VT and blood glucose in diabetics. Conclusion QTT is a sensitive method for diagnosis of diabetic neuropathy.

OBJECTIVETo investigate the effects of closed reduction and ulna intramedullary nail fixation for the treatment of fresh Monteggia fractures of Bado type I and II in children.

METHODSTwenty-three children patients with Monteggia fracture during July 2010 to September 2013 were treated by closed reduction and ulna intramedullary nail fixaion including 18 boys and 5 girls with an average age of 9.3 years old ranging from 6 to 13 years old. Among them,15 cases were Bado type I and 8 cases were Bado type II. There were 9 cases with radial nerve injury. The operation time,the recovery of nerve injury, the fracture healing and the function of elbow were observed and recorded.

RESULTSAll patients were followed up for 6 to 24 months (12 months on average). All patients were obtained bone healing. According to Anderson standard, at the final follow-up, 20 cases got excellent result, 2 cases got good result, and one case got fair result.

CONCLUSIONTreatment of the fresh Monteggia fractures in children by closed reduction and ulna intramedullary nail fixation has advantages of simple operation, less trauma and good results.

Objective: To study the phenotype characteristic of mandibular condylar chondrocytes (MCCs) in vitro. Methods: MCCs of two-week-old New Zealand rabbits were isolated with enzyme digestion and cultured in DMEM. Phase contrast microscopy, image analysis system, MTT assay and immunocytochemistry method were used to compare MCCs of different passages in cellular shape and size, growth curve and expression of type I and type II collagen. Results: The majority of MCCs in earlier passages (1～3 passage) were polygonal, while more fusiform and spindle-shaped cells were found after 5～6 passages. MCCs in earlier passages were smaller than those in sixth passages. The proliferation rate of MCCs decreased with passaging. There were more type II collagen positive cells in 1 ～ 3 passages, while more type I collagen positive cells in 7th passage. Conclusion: The changing characters of MCCs in vitro such as cellular shape and size and expression of type I and II collagen are similar to those of MCCs in vivo from proliferating zone to hypertrophic zone. MCCs in later passages may be with dedifferentiation.

Objective To investigate the efficacy of minimally invasive percutaneous nephrolithotomy(MPCNL) for impacted upper ureteric calculi.Methods Retro-urethral catheterization was conducted in the diseased ureter under cyctoscope.After a channel from the skin surface into the middle calyx was established under the guidance of X-ray or B ultrasonography,pneumatic lithotripsy was conducted to break up stones under ureteroscopy.Results The success rate of pneumatic lithotripsy was 100%.The rate of postoperative macroscopic hematuria was 55.1%(27/49).The symptom lasted one to three days in 26 cases,and 1 case had apparent hematuria with blood clot flowing out from nephrostomy tube,which lasted 8 days.10.2%(5/49) of cases was complicated with postoperative pyrexia.The stone-free rate in one week and one month postoperatively was 93.9%(46/49) 98.0%(48/49),respectively.Follow-up observations in 49 cases for 1-12 months(mean,5 months) showed no major complications.Conclusions MPCNL for impacted upper ureteral calculi has the advantages of simple performance,less complications and satisfactory efficacy.
