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 assess the efficacy and safety of transurethral bipolar plasmakinetic resection of benign prostatic hyperplasia (BPH). Methods A total of 45 cases of BPH were treated by transurethral bipolar plasmakinetic resection of prostate (PKRP) and were followed up for 3-10 months.Results The weight of the resected prostate was 28-105 g with an average of (47?16) g, the operation time was 15-120 min with an average of (50?12) min. No case needed blood transfusion during the operation and no transurethral resection syndrome occurred. The mean catheterization time was 4 d and the mean postoperative hospital stay was 7 d. Peak urine flow increased from (7.3?1.5) ml/s to (16.2?4. 4) ml/s and IPSS decreased from (27.6?1.3) to (5.8?1.0) in 3 months postoperatively. Conclusion Transurethral bipolar plasmakinetic resection of prostate is effective and safe with less complications.

Objective To improve the diagnosis and treatment of adenocarcinoma of bladder. Methods The data of 20 cases of adenocarcinoma of bladder from 1986 to 2004 were retrospectively analyzed. All patients underwent operation and the diagnosis was proven by histopathologic examination. Results Eighteen cases were primary adenocarcinoma of bladder,8 cases applied to radical cystectomy and 10 cases partial cystectomy. Two cases were urachal adenocarcinoma,and received extended partial cystectomy.Seventeen patients were followed up for 3 months to 5 years. The one-year survival rate was 52.9% (9/17),two-year survival rate 41.2% (7/17),and five-year survival rate 29.4% (5/17). Conclusion Radical total cystectomy is the best choice for primary adenocarcinoma of bladder and extended partial cystectomy for urachal adenocarcinoma. Radiotherapy and chemotherapy after operation can improve the treatment effect.

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.

To investigate the therapeutic effect of artesunate on mouse cytomegalovirus pneumonia, the BALB/c-nu mice were infected with murine cytomegalovirus-green fluorescent protein (MCMV-GFP) by nose dropping method. The experimental protocol was approved by the Medical Laboratory Animal Ethics Committee of Guangzhou Medical University. The BALB/c-nu mice were randomly divided into five groups: control group, MCMV pneumonia group, and artesunate (60, 120, and 240 mg·kg-1) groups. The survival rate, weights, and virus loads in lungs among the groups were observed. The degree of histopathologic changes in lungs was assessed directly by hematoxylin-eosin (HE) assay. MCMV-GFP expression was assessed by immunofluorescence. In addition, reverse transcription polymerase chain reaction (RT-PCR) analysis was performed to investigate the content of major immediate early 1 (

The regulation mechanism of arecoline on rat hepatic CYP2E1 was studied in vivo. After oral administration of arecoline hydrobromide (AH; 4, 20 and 100 mg x kg(-1) x d(-1)) to rats for one week, the hepatic CYP2E1 mRNA level remained unchanged, but the hepatic CYP2E1 protein content was dose-dependently increased. Additionally, although the hepatic CYP2E1 activity was induced by AH treatment, the induction was attenuated with the increase in dosage. The results indicate that the effect of arecoline on rat hepaticdoes not involve transcriptional activation of the gene, but largely involves the stabilization of CYP2E1 protein against degradation or increased efficiency of CYP2E1 mRNA translation, and additionally involve the post- ranslational modification of CYP2E1 protein. Furthermore, the CYP2E1 response is fairly equal among the different species, the induction of rat hepatic CYP2E1 by arecoline suggests that there is a risk of metabolic interaction among the substrate drugs of CYP2E1 in betel-quid use human.

Objective To explore the effects of surface modification of PLGA-[ASP-PEG] scaffold with typeⅠcollagen on the adhesion,proliferation and osteogenic differentiation of rabbit bone marrow stromal cells (BMSCs).Methods After PLGA-[ASP-PEG] materials were modified with typeⅠcollagen chemically,the collagen was coated onto the materials physically.The BMSCs obtained from rabbits were cultured on the modified PLGA-[ ASP-PEG] and on the unmodified PLGA-[ ASP-PEG] as control.The adhesion and proliferation behavior of the cells was analyzed and the expressions of osteogenie marker alkaline phosphatase,osteocalcin,osteopontin,typeⅠcollagen and core binding factor al were also detected.Results X-ray photoelectron spectrometry(XPS) confirmed that TypeⅠcollagen was grafted onto the surface of PLGA-[ASP-PEG] successfully and the collagen content on the materials modified chemically and physically was significantly increased.The abilities of adhesion and proliferation and the expressions of osteogenie makers of the BMSCs were significantly greater than those in the control group(P<0.05).Conclusion Since Type collagen I can improve the biocompatibility of PLGA- [ASP-PEG] scaffold materials,it can be used as a new way to optimize scaffolds in tissue engineering.
