Myelodysplastic syndromes (MDS) is a heterogeneous group of clone bone marrow disorders.The diagnosis of MDS can be challenging when dysplastic features are minimal and cytogenetic analysis shows no abnormalities The high sensitivity of flow cytometry (FCM) in the detection of dysplasia in myeloid lineages makes it a valuable tool to distinguish possible clonal causes of cytopenia(s) from nonclonal causes.Due to the heterogeneity and absence of specific FCM markers for MDS,the immunophenotyping of MDS by FCM remains a big difficulty.Here we will focus on how to perform immunophenotyping of MDS by FCM and the potential diagnostic,prognostic and therapeutic value of FCM in MDS.

OBJECTIVE: To evaluate the therapeutic effect of multi-plane operations in treating obstructive sleep apnea-hypopnea syndrome (OSAHS). METHOD: One hundred and fifteen patients with OSAHS diagnosed by polysomnography were treated with uvuplopalatopharyngoplasty. Eighteen of them were treated combining with nasal septal construction. Twenty six patients also received nasal septal construction and partial inferior turbinectomy. One patients also received Genioglossus advancement and partial resection of corpus linguae. Five patients also received partial resection of corpus linguae. Some patients with the nasal disease and/or the lingual hypertrophy; AHI > 40 and/or BMI > 30 are received tracheotomy before general anaesthesia. RESULT: According to the postoperative follow-up 43 patients, were cured, 46 patients were improved, 26 patients were invalid, the effective power was 77.4%. CONCLUSION The operative effective power were increased by multi-plane operations in OSAHS patients. The serious complication were prevented through tracheotomy before general anaesthesia in multi-plane operations of severe OSAHS.

Objective To discuss the clinical feature of chronic pain of aged people and strategies and effect of its self-management as well as their relationship.Methods Investigation with questionnaires wag carried out in 243 aged people who were above 65 years old to understand the clinical feature of chronic pain and strategies of its self-management.The results underwent analysis.Results Non-narcotic analgesics,physical exercise,cold and heat therapy and spiritual activity were used most frequently in selfmanagement of pain.No statistical difference existed in the use of self-management strategies between people in different age groups.Effect of self-management strategies was negatively correlated with degree of pain,interrupting with daily life and anxiety,but Wag positively correlated with self-efficacy score.Conclusions Aged people ale willing to attemp various strategies to cope with chronic pain.We should pain attention to the standardization of physical exercise,confrontation of anxiety and improvement of self-efficacy to improve the effect of self-management.

Objective To establish a scientific and normative process for using physical restraint,and to increase the safety and efficiency of physical restraint.Methods On the basis of the previous studies,combined with the literature and clinical,we drafted a process framework of using physical restraint and then conducted consultation from 11 experts by using the Delphi technique.Results After 2 rounds of consulting,an evaluation form,consisted of 4 first-dimensions and 11 second-dimensions,and a process,consisted of 4 first-dimensions and 26 second-dimensions,were established.Kendall's W were 0.37 and 0.38 respectively,and expert authority coefficient was 0.84.Conclusions The results from the study is valid,feasible and reliable,however it still need to be further perfected.

ObjectiveTo investigate the condition of hospital staff in surgery and internal medicine department in a specified hospital for consent of patients. MethodsThis study included 50 hospital staff in surgery and internal medicine department in specified hospital at the second level in Chongqing city in May 2010. We also analyzed the dealership of children and psychopath, consent of patients or relatives for choosing hospitals. ResultsThe ratios of cognition of hospital staff for consent of patients were 68％ and 46％, which had statistical difference ( P＝0.026 ). The main ways were radio and television. About 97％ hospital staff knew that it's hospital staff s duty to inform relative information to patients. ConclusionMedical legislation department and medical institutions should enhance the study of hospital staff on relative laws and regulations. Thus hospital staff have a in-depth understanding on information of consent of patients.

AIM: To study the effects of the composite lactogenic decoction (CLD) on milk secretion of hypoprolactinemia induced by L dopa in rats.

Levels of serum prolactin were detected by ELISA and the mammary gland histology was observed by electron microscop. RESULTS: The administration of CLD (3, 6 and 20 g?kg -1 ) by the way of ig increased serum prolactin (PRL) level significantly (P

Purpose To investigate the effect of resveratrol on acute lung injury induced by lipopolysaccharide (LPS) in mice.Methods Acute lung injury (ALI) was induced by LPS in mice. The changes of lung airway inspiratory resistance (Ri), expiratory resistance (Re), and dynamic lung compliance (Cdyn) were observed with pulmonary function test apparatus. Brochoalveolar lavage fluid (BALF) was collected, and the concentrations of interleukin 1β (IL-1β)、interleukin 6 (IL-6) and tumor necrosis factory α (TNF-α) were measured by ELISA. The ratio of wet to dry weight was calculated to assess lung edema. Pulmonary vascular permeability was examined with injection Evans blue to judge the destructive extent of alveolar epithelial cell and endothelial. Pathological section was made, and the histopathological change was observed with light microscope.Results Resveratrol can inhibit the elevation of Ri and Re, and the descent of Cdyn. Simultaneously, resveratrol reduced the concentration of IL-1β, IL-6 and TNF-α,as well as the wet to dry weight ratio and the pulmonary vascular permeability significantly. Furthermore, it also could attenuate the lung injury on histopathology.Conclusion The results show that pretreatment with resveratrol has a protective effect on ALI induced by LPS. The ultimate inhibiting and release of inflammatory factors were involved in the mechanism of the effects.

Objective To determine if activation of AMP-activated protein kinase (AMPK) is involved in ropivacaine-induced reactive oxygen species (ROS) production and apoptosis in human neuroblastoma cell line SHSY5Y.Methods SH-SY5Y cell line was purchased from cell center of Shanghai life Science Research Institute,Chinese Academy of Sciences and cultured in DMEM/F12 liquid culture medium containing 15 % bovine calf serum at 37 ℃ in incubator filled with 5% CO2 .
