JM is a acute lymphocytic leukemia cell line derived from immature T lymphocytes in human thymus.We bserved the immunoregulation effect of supernatants from JM cell culture(SPN_(JM))onproliferation of human B ymphocytes and mouse spleen cells by using purified human B lymphocytesand mouse spleen cells stimulated with AC.It is showed that SPN_(JM),which suppresses T lymphocyteproliferation,enhance the proliferation response of uman B cell and mouse spleen cells stimulatedwith SAC.Without inducement of SAC,SPN_(JM) with HrIL-2 still nhances B lympohocyteproliferation.Additionally,SPN_(JM) is able to up regulate T cell proliferation response at lowconcentration(1:640)although it suppresses T cell proliferation at high concentration.

OBJECTIVE:To compare the efficacy and safety of different density of Levobupivacaine for combined spinal and epidural anesthesia (CSEA) in elder patients. METHODS: Sixty elder patients undergoing transurethral prostatectomy (TURP) were randomly assigned to 1 of the 3 groups: Group Ⅰ(n=20,hypobaric group) received 0.75% Levobupivacaine 1 mL+ 0.5 mL 0.9% Sodium Chloride Injection,Group Ⅱ(n=20,isobaric group) received 0.75% Levobupivacaine 1 mL+0.5 mL cerebrospinal fluid,and Group Ⅲ(n=20,hyperbaric group) received 1 mL 0.75% Levobupivacaine+0.5 mL 10% Glucose. RESULTS: All the 3 groups achieved satisfactory anesthetic efficacy. The incidences of hypotension,nausea,vomiting and shivering were significantly lower in Group Ⅲ than in other two groups (Group Ⅰ and Group Ⅱ)(P

Plastic bronchitis is a “multiple-system” involved syndrome that is characterized by the formarion of thick,arborizing mucofibrinous tracheobronchial casts,which can result in hard breathing or pulmonary failure.Plastic bronchitis in children occurs following correction of complex cardiac defects,or in children with inflammatory pulmonary conditions.It is a condition of unknown causes and has different clinical manifestations.Early diagnosis is very important and so far endoscopic removal of the casts is the most effective measure.

Objective To compare the level of glycosylated hemoglobin (HbA1c) in patients with diabetes treated with actrapid monotard analog or actrapid monotard. Methods One hundred and twenty patients with type 2 diabetes were divided into actrapid monotard analog group and actrapid monotard group with 60 cases in each by admission number. Fasting blood glucose (FBG), 2-hour postprandial blood glucose (2hPBG), HbA1c were obtained and analyzed. Results The overall cure rate were similar between actrapid monotard analog group and actrapid monotard group (83.3%, 50/60 vs. 86.7%, 52/60, P ＞ 0.05 ). There was no significant difference in FBG, 2hPBG before treatment between two groups (P ＞ 0.05),but there was significant difference at 2 weeks after treatment between two groups (P ＜ 0.05 ) . There was no significant difference in HbA1c before treatment between two groups (P＞ 0.05 ) ,but there was significant difference at 3 months after treatment between two groups (P ＜ 0.05 ). FBG, 2hPBG, HbA1c after treatment were improved compared with before treatment in two groups (P ＜ 0.05 ). Conclusion Actrapid monotard analog provides better blood glucose control compare with actrapid monotard while providing the convenience of injecting immediately before meals.

OBJECTIVE:To investigate the feasibility of defined individual treatment course as evaluation index of rational use of drugs.METHODS:The doses of antibiotics and treatment course in 63 patients with type Ⅰ incision operation of our hospital in Jan.2010 were taken as examples.Case analysis,DUI evaluation and defined individual treatment course evaluation were adopted.Similar results were obtained by 3 kinds of methods.RESULTS&CONCLUSION:Results of 3 kinds of methods are consistent.DUI evaluation isn't closely associated with treatment course.Defined individual treatment course is more sensitive and available than DUI based on the introduction of dose and treatment course.

P2 X7 receptor is a member of ATP-gated non-selective cation channels;and is one subtype family of the P2X purinergic receptor.Signaling pathways of P2X7 receptor couple with several key inflammatory molecules including IL-1β;IL-6 and COX-2;which suggests that P2 X7 receptor plays a key role in the development of dis-eases via increased inflammation;indicating its potential as a novel therapeutic target.Recent studies show that P2 X7 receptor has a relationship with renal diseases.This article reviews the effect of P2 X7 receptor on renal diseases and its mechanism.P2 X7 receptor may be a new drug target;and its selectivity antagonist may be a new therapeutic agent for the treatment of renal diseases.

In condition of direct vision on fundus of eye, microperimeter can quantitatively detect the retinal light sensitivity of macular area, and record real time tracking of the eye, automatically analyze the location and stability of fixation. Microperimeter matches fundus image with micro cyclogram point-to-point, thus it achieves the combination of visual function and structure. The characteristics of microperimeter have good relations with subjective vision, so it can be a new method for the accurate vision evaluation and has application potential to assess the visual function in legal medicine. In this ar-ticle, we summarize the principle, method and parameters of microperimeter. Also, the applications of microperimeter in vision assessment are focused in order to provide a reference for the assessment of visual function in the legal medicine.

Objective:To presents a new way of constructing post crowns for the anterior maxillary teeth which had the subginginval crown fracture more than 3 mm.To discusse the difficulties in the restoration of the subgingival residual roots and residual crowns of anterior maxillary teeth,and to explore the principles of the new restoration by the casting post-core and the porcelain fused mental crowns with wings. Methods: 23 patients(26 teeth) which had crown fracture more than 3 mm under the gingival were enrolled in this study.After those residual roots and crowns were endodontically treated following the conventional root canal therapy,the casting post-core and the porcelain fused mental crowns with wings were applied to reconstructing those missing crowns. Results: After 3 months to 5 years clinic observation,restored crowns were still stable with good retention and fracture resistance. Conclusion: Those residual roots and crowns can be preserved by this innovative way and can also acquire satisfactory effects in esthetics and functions.

Recently,increasing evidence suggests that gingivitis and periodontitis may be one of the etiological factors for some adverse pregnancy outcomes such as preterm birth,preeclampsia,fetal growth restriction and lateral miscarriage.Although there are some conflicting findings and potential problems regarding uncontrolled underlying risk factors,most of the clinical studies indicate a positive correlation of gingivitis and periodontitis with those complications.This review discusses the relationship and its possible pathological mechanism in order to better prevent the development of adverse pregnancy outcomes.

Recent research results suggest the existence of cancer stem cell (CSC), a subpopulation of cells with tumorigenic potential that is present in tumor. It has been reported that the occurrence of some tumors is closely related to mesenchymal stem cell as origin of stroma cell. This review discuss the relationship among mesenchymal stem cell, cancer stem cell and cancer.
