ObjectiveTo discuss the effect of surgical treatment of varicose vein on primary chronic venous insufficiency(PCVI) in the lower extremities.MethodsBetween August 2007 and August 2008,128PCVIpatients underwenthighligationof the greatsaphenousveinandendovenous electrocoagulation of the varix superficial vein. Spectrum Doppler ultrasound was used to measure the superficial femoral vein blood flow hemodynamic information beneath the first pair of valve including quiet breathing condition and the Valsalva action (reflux time、caliber、reflux velocity). Reflux index (RI) was used as guide line.ResultsClinical sympotoms improved in 54 out of 60 mild PCVI cases, in 29 of 45 moderate PCVI patients, while only in 6 out 23 cases in whom severe preoperative clinical symptom with PCVI was present.The effective rate respectively was 90％, 64％, and 30％.The mild reflux index significantly improved than that before operation ( t = 21. 484, P = 0. 000 ), the moderate reflux index improved than that before operation ( t = 2. 173, P = 0. 035 ), while the serious reflux index were not statistically improved than that before operation( t = 1. 888, P = 0. 078 ). In all cases reflux index improved after the surgery ( x2 = 8. 266,P = 0. 004).ConclusionsMinimally invasive surgical treatment of varicose veins can improve the reflux of the deep vein in PCVI cases with mild to moderate clinical symptom.

OBJECTIVETo analyze the effect of Chinese herbs used by Prof. LI Tao on peripheral blood T subsets in treating multiple sclerosis (MS) by using association rules and statistical methods, thereby providing evidence for optimizing prescriptions.

METHODSData of MS inpatients and outpatients recorded by data collecting system, Xiyuan Hospital, China Academy of Chinese Medical Sciences were resorted. The relationship between Chinese herbs and T cell subsets were analyzed using SPSS17.0 and Aprior module in SPSS Clementine 12.0.

RESULTSRadix bupleuri, Radix Paeoniae alba, Fructus Aurantii, Atractylodes, and Radix Glycyrrhizae were most commonly used herbal combinations.Radix Aconiti lateralis preparata and Rhizoma Smilacis glabrae were often added. Radix Aconiti lateralis preparata was associated with decreased Th1 cells (confidence level 83.78%, supportive level 36.26%). Decreased Th1 cell was associated with Radix Aconiti lateralis preparata (confidence level 71.26%, supportive level 36.26%).Radix Aconiti lateralis preparata was obviously associated with decreased Th1 cells. Radix Bupleuri, Radix Paeoniae alba, bitter orange, Atractylodes , Radix glycyrrhizae, and Radix Aconiti lateralis preparata could reduce peripheral blood Th1 subsets of MS patients and elevate Th2 subsets (all P < 0.01).

CONCLUSIONSThe herbal combination of Radix Bupleuri, Radix Paeoniae alba, Fructus Aurantii, Atractylodes, Radix Glycyrrhizae, Rhizoma Smilacis glabrae, and Radix Aconiti lateralis preparata could lower peripheral blood Th1 cells and elevate Th2 cells, and prevent the relapse of MS possibly by reducing Th1 cells and elevating Th2 cells. Especially Radix Aconiti lateralis preparata played important roles in aforesaid changes of Th1 and Th2.

Objective:To compare the sedative effect and safety of different doses of dexmedetomidine in the patients undergoing total abdominal hyserectomy. Methods:A total of 120 patients undergoing total abdominal hysterectomy were randomly divided into four groups, different doses of dexmedetomidine groups(D1 group, D2 group and D3 group)and midazolam group(M group) with 30 pa-tients in each. Dexmedetomidine groups received intravenous pump infusion of dexmedetomidine (0. 5 μg·kg-1 ) 10 minutes before the operation, and then the different dexmedetomidine groups were received continuous infusion of dexmedetomine of different doses:D1 group of 0. 4μg·(kg·h) -1, D2 group with 0. 6μg·(kg·h) -1 and D3 group with 0. 8μg·(kg·h) -1;M group received in-travenous pump infusion of midazolam (0. 06 mg·kg-1) 10 minutes before the operation, and then with 0. 04 mg·(kg·h) -1 con-tinuous infusion. The mean arterial pressure( MAP) , heart rate( HR) , respiratory rate( RR) , oxyhemoglobin saturation( SpO2 ) were recorded at the following time points:the moment of entering the operating room(T0), the block effect of epidural anesthesia was satis-fied (T1),10 min(T2),20 min(T3)and 40 min(T4)after the drug infusion, and the end of the operation(T5), and the duration of the medicine use and the whole operation were recorded as well. The sedation degrees were evaluated with Ramsay scale, and the am-nesic scores, adverse drug reactions and patient satisfaction were recorded after the operation. Results:Compared with that of the other groups, HR of D3 group was obviously lower after T3 (P<0. 05);and after T2, HR was significantly lower than that at T0 (P<0. 05 or P<0. 01). Compared with the other groups, RR of M group was obviously lower at T3 and T4 (P<0. 05). Compared with those at T0 , the sedative effects of all the groups were much remarkable(P<0. 05 or P<0. 01);and the Ramsay score of D3 group at T3 and T4 was higher than that in D1 group or M group(P<0. 05). There were no obvious adverse reactions in the four groups. Conclusion:The use of dexmedetomidine in the patients undergoing total abdominal hyserectomy might not lead to the risk of respiratory depression as the use of midazolam, while the dose of dexmedetomidine should be less than 0. 8 μg·(kg·h) -1.

Objective To prospectively evaluate the value of cystatin C (CysC) in diagnosis of contrast-induced acute kidney injury (CIAKI) among patients undergoing Percutaneous Cardiovascular Intervention (PCI).Methods Patients who underwent PCI procedures in our hospital were enrolled.Serum creatinine(SCr) and CysC were measured at baseline before,24 h and 48 h after PCI,respectively.CysC were examined by particle-enhanced turbidimetric immunoassay (PETIA).CIAKI was defined as a relative increase in SCr concentration of at least 25％ or an absolute increase more than 44.8 mmol/L (0.5 mg/dl) within 48 h in the absence of other related causes.Results Among 196 patients,135 were male and 61 female with a mean age of(70.4 ± 11.3)years old.Twenty-nine (14.8％)patients developed CIAKI according to the SCr criteria.The area under the ROC curve (AUC) at 24 h and 48 h post PCI were 0.661 (95％ CI 0.548-0.774,P =0.006) and 0.783 (95％ CI 0.701-0.865,P ＜ 0.001),respectively.The diagnostic sensitivities of CysC at 24 h and 48 h were between 6.9％ and 48.28％,while,the diagnostic specificities and negative predictive values of CysC were between 85.03％-97.60％ and 85.79％-90.45％,respectively.The 15％ elevation of 48 h CysC yielded the diagnostic sensitivity of 41.38％,specificity of 92.86％,negative predictive value of 90.17％,corrective rate of 85.28％ with Youden Index of 0.342 4.Conclusions In this study,CysC presented an excellent diagnostic specificity and negative predictive value in diagnosis of CIAKI.It might be used as a tool for excluding CIAKI in clinical practice.48 h CysC performed better than 24 h CysC in CIAKI diagnosis,among which a 15％ increment achieved relatively the best diagnostic value.

Objective To evaluate the clinical outcome of one-level posterior lumbar interbody fusion (PLIF) performed with microendoscopic approach.Methods A consecutive series of 56 patients who under went one-level PLIF procedure(24 cases performed with microendoseopic approach and 32 cases with tradition- al open approach)were studied from January 2005 to May 2006.The following data were compared between 2 groups with 12 to 27 months follow-up:estimated blood loss,postoperative drainage,transfusion needs,surgi- cal time,length of hospital stay,postoperative back pain by visual analogue scale,complications,and the clinical and radiographic results.Results The microendoscopic approach was found to have a significantly less blood loss,less postoperative drainage,less needs of transfusion,less postoperative back pain,shorter re- covery time and shorter length of hospital stay.However,the microendoscopic approach needed significantly longer surgical time.There was no significant difference between 2 groups in the aspects of the complications and the clinical and radiographic results.Conclusion The one-level PLIF performed with microendoscopic approach minimize estimated blood loss,length of hospital stay,postoperative back pain.It also shows the ex- cellent surgical efficacy of the microendoscopic approach for suitable patients.

Intervertebral disc degeneration is considered as a primary cause of clinical low back pain, however the molecular mechanism is not clear yet. Recently, researches on the molecular basis of intervertebral disc degeneration have become a hotspot. The special structure and biomechanics properties of the disc contribute to its propensity toward degeneration. Intervertebral disc degeneration is associated with the changes of the cytological behavior,including the increase in cell death and the degradation of extracellular matrix. However, the mechanism of cell death including cell apoptosis and autophagy in intervertebral disc degeneration remains unclear. Further study on the molecular mechanism of intervertebral disc degeneration is the foundation of improving and treating the intervertebral disc degeneration in the future. Although some progresses are made in the aspect of biological study, the biological environment of intervertebral disc itself is still a challenge for the development of biological treatment. This article is to review the latest advance on the biological characteristics of normal intervertebral disc and the cell death in the process of the intervertebral disc degeneration.

OBJECTIVETo explore the effect of Sedum sarmentosum Bunge Extract (SSBE) on severe acute pancreatitis (SAP) induced acute lung injury (ALI) model rats and their excessive inflammatory reactions.

METHODSForty-two healthy adult male Sprague-Dawley (SD) rats were randomly divided into 3 groups, the sham-operated control group (C), the SAP group (SAP), and the SSBE treated group (SSBE), 14 in each group. SAP induced ALl rat model was induced by retrograde injection of 5% sodium taurocholate (1 mL/kg) into the pancreatic duct. SSBE (100 m/kg) was administrated subcutaneously after the establishment of the SAP model. Equal dose of SSBE was injected again 12 h later. Equal volume of normal saline was administrated in the same way for rats in the C group and the SAP group. Rats were sacrificed after successful modeling and samples taken at 12 and 24 h. Pathological changes in the pancreas and the lung tissue were observed under light microscope. The ascites, serum amylase (AMS), wet/dry proportion (W/D) of the lung tissue, activities of myeloperoxidase (MPO), interleukin-1 (IL-1), IL-6, and tumor necrosis factor-alpha (TNF-alpha) were also measured.

RESULTSAscites and serum AMS activities significantly increased; MPO, IL-1, IL-6, TNF-alpha contents, and W/D ratio also significantly increased in the SAP group, when compared with the C group (P<0.05). Compared with the SAP group, those parameters were all attenuated in the SSBE group at 12 and 24 h (P<0.05, P<0.01). Pathological changes in the pancreas and the lung tissue were alleviated in the SSBE group under light microscope. The injury degree ranged between that of the C group and the SAP group.

CONCLUSIONSSBE could relieve the ALl in SAP model rats, which could be achieved through alleviating inflammation responses of SAP rats.
