Objective:To detect the expression of IL-17A、IL-10 and IFN-? in patients wth different forms of inflammatory bowel disease(IBD) during clinical remission phase and investigate their role in the onset and treatment of IBD.Methods:Tissue samples were obtained from patients with ulcerative colitis(UC,n=46),Crohn's disease(CD,n=12),and normal colorectal tissues(n=20).IL-17A expression was evaluated by a standard immunohistochemical procedure.Serum IL-17A、 IL-10 and IFN-? levels were determined by ELISA.Results:IL-17A expression was not detected in samples from normal colonic mucosa but was present in the mucosa of IBD.The level of IL-17A significantly increased in IBD patients while it was not detected in the sera of normal individuals.The level of IL-10 in patients with Crohn's disease was significantly higher than that in patients with ulcerative colitis and control group(P

The somatostatin analogue pasireotide is a new type of protein which is the first therapeutic agent targeted to the pituitary.Pasireotide can prevent adrenocorticotropic hormone release and inhibit the growth of tumor cells after coupling with somatostatin receptor of the target cell membranes.Pasireotide has a high binding affinity for most of somatostatin receptor (SSTR) subtypes and in particular for SSTR5.Pasireotide can paly an important role in the new round of new targets for individualized diagnosis and treatment of tumors through the studies of translational medicine.

AIM: To explore the effects of selenium-enriched Spirulina platensis (Se-SP) on proliferation of hepatocytes in rat hepatectomy. METHODS: Rat hepaectomy model was conducted using male Wistar rats. The rats were randomized into five groups: operation groups with 150 (H), 50 (M) and 15 (L) mg?kg-1?d-1 of Se-SP, placebo-control (P) and sham operation group (F). Activities of glutathione peroxidase (GPx) and thioredoxin reductases (TR) in hepatocytes were determined by chemical colorimetry. The expression index of proliferating cell nuclear antigen (PCNA) in hepatocytes was detected by immunohistochemistry, and the level of [3H]-TDR incorporation in regenerative hepatocytes was analyzed by radio-immunity. RESULTS: Activity of GPx and TR, PCNA expression index as well as [3H]-TDR insertion in hepatocytes (in vitro) were obviously higher (P

Objective To explore the effects of selenium enriched Spirulina platensis(Se-SP) on(antioxidation) and regeneration of rat hepatocytes after partial hepatectomy.Methods Sixty-seven percent(hepatectomy) was performed in rats after high dose(H) and low dose(L) Se-SP was given via gastric tube for 7 days.Then selenium(Se),glutathione peroxidase(GPx),superoxide dismutase(SOD) and(malondiaoldehyde)(MDA) in hepatocytes were determined.The results were compared with normal saline(giving) via gastric tube before hepatectomy(C) and sham operation(S) groups.Hepatocytes were obtained(before) operation and 24h after operation,and the expression index of proliferating cell nuclear antigen((PCNA)) in hepatocytes was detected by immunohistochemistry,and the DNA damage of hepatocytes induced by peroxide was analyzed by comet assay.Results After partial hepatectomy,Se content,GPx and SOD(activity),and PCNA expression index were obviously higher(P

Incomplete CCC leading to posterior capsule tears was 9.38% and zero in two groups respectively.CONCLUSION: Controlled CCC technique can increase the success rate and reduce complications in short axial length and shallow anterior chamber eyes.KEYWORDS:phacoemulsification; continuous curvilinear capsulorhexis; complication

Objective To determine the efficacy of hysteroscopy and laparoscopy in differential diagnosis of pregnancy-related diseases,including gestational trophoblastic neoplasia(GTN),incomplete abortion and ectopic pregnancy.Methods Twenty-seven patients with a suspected diagnosis of GTN were transferred to Peking Union Medical College Hospital from September 2003 to March 2006,and underwent hysteroscopy and laparoseopy.Clinical data of patients were reviewed retrospectively.Most patients had abnormal vaginal bleeding and persistently elevated plasma beta human chorionic gonadotropin(?-hCG) level for a median(53?37)days(range,15-125 days)after evacuation.Ultrasound revealed a lesion with affluent blood flow in intrauterine,unilateral horn of uterus,or myometrium.No positive findings were revealed by computerized tomography or X-ray of the chest in all patients.Eleven patients underwent evacuation under hysteroscope,10 patients were diagnosed and treated by laparoscopy,and 6 by hysteruscopy and laparoseopy.Results Choriocarcinoma was diagnosed in 4 patients,who achieved complete remission by chemotherapy later.The diagnosis of GTN was ruled out in the other 23 patients, including cornual pregnancy in 12,pregnancy in rudimentary horn in 1,and incomplete abortion in 10,who were cured by hysteroscopic and laparoscopic surgery and postoperative adjuvant single dose methotrexate.Conclusions The major causes of pregnancy-related abnormal bleeding include incomplete abortion,eetopic pregnancy,and GTN.Hysteroscopy and laparoseopy are effective alternative of diagnosis for differentiation of GTN from non-GTN and can also offer therapeutic treatment.

0.05).Compared with control group,significant decrease in positive group was found in the interval from first evacuation of HM to resolution of serum ?-hCG level,(83?18) days versus(126?31)days(P0.05).Conclusions Once HM is diagnosed,evacuation should be performed as soon as possible,the later the evacuation begins,the higher the risks of lung metastasis and chemotherapy are.It is not necessary to worry about lung metastasis before evacuation of HM,the outcome of post- chemotherapy is very good.

Objective To explore the effects of extract of Gingko biloba leaves (EGb) on learning, memory and hippoeampal heine oxygenase-1 (HO-1) expression in diabetic rats.Methods The behaviors of streptozotoein-induced diabetic rats were observed by Morris water maze for learning and memory after 6 months of diabetes.The HO-1 mRNA expression and protein expression in hippocampus of diabetic rats were detected by RT- PCR and immunohistochemistry respectively.Results The escape latency time in Morris water maze of diabetic rats was prolonged markedly.HO-1 mRNA and HO-1 protein expressions in hippocampus of diabetic rats were increased (1.635?0.326 vs 0.978?0.214,7.2?1.7 vs 1.9?0.5,respectively,both P＜0.01).The escape latency times in EGb (100,50 mg/kg) treated groups were shortened.HO-1 mRNA and HO-1 protein expressions in hippocampus were decreased at the same time as compared with diabetic group (100 mg/kg:0.954?0.144,2.0?0.8;50 mg/kg:0.988?0.154,2.5?0.6,all P＜0.01).Conclusion EGb can significantly inhibit HO-1 expression in hippocampus and improve learning and memory dysfunction in diabetic rats.

OBJECTIVETo evaluate the efficacy and safety of the combination therapy of Xipayimaizipizi Capsules and Tamsulo- sin in the treatment of benign prostatic hyperplasia (BPH).

METHODSWe randomly assigned 60 BPH patients to a control and a combination group of equal number, the former aged 62.03 ± 10.19 years with a disease course of 3.24 ± 2.18 years and the latter aged 64.77 ± 10.33 years with a disease course of 4.09 ± 2.63 years. We treated the patients in the control group with Tamsulosin at 0.2 mg qd and those in the combination group with Tamsulosin at 0.2 mg qd plus Xipayimaizipizi at 0.5 g tid, respectively, both for 4 weeks. Then, we obtained the mean frequency of nocturnal urination, maximal urinary flow rate (Qmax), residual urine volume, International Prostate Symptom Score (IPSS) , and quality of life scores (QOL) of the patients, and recorded their adverse reactions.

RESULTSBefore treatment, the nocturnal urination frequency, Qmax, IPSS, and QOL were 3.60 ± 1.81, (10.40 ± 3.53) ml/min, 22.47 ± 8.58, and 4.43 ± 1.50 in the control group, as compared with 3.43 ± 1.61, (10.14 ± 3.43) ml/min, 21.93 ± 8.79, and 4.73 ± 1.31 in the combination group. After 4 weeks of medication, the combination group showed more significant improvement than the control in the nocturnal urination frequency (1.30 ± 1.18 vs 2.27 ± 1.60), Qmax ([13.85 ± 3.15] vs [14.36 ± 3.03] ml/min), IPSS (13.00 ± 1.53 vs 17.20 ± 8.43), and QOL (2.57 ± 1.61 vs 2.93 ± 1.68), all significantly better than the baseline (P < 0.05). The combination therapy achieved remarkable improvement as compared with the control in the nocturnal urination frequency (- [2.13 ± 1.11] vs -[1.73 ± 1.07]), IPSS (- [8.93 ?6.01] vs -[4.80 ± 3.87]), and QOL (- [2.17 ± 1.12] vs -[1.50 ± 1.01]) (P < 0.05), but exhibited no significant differences from the latter in Qmax ([3.72 ± 2.281 vs [3.95 ± 2.53] ml/min) and residual urine volume (- [34.30 ± 37.43] vs - [26.43 ± 30.49] ml) (P > 0.05). Adverse reactions were found in 5 cases in the combination group (16.67%) and 3 cases in the control (10%) , with no remarkable differences between the two groups (P > 0.05).

CONCLUSIONThe combination therapy of Xipayimaizipizi Capsules and Tamsulosin can improve the symptoms of BPH and the patients quality of life of.

Thrombotic diseases in different forms become a great threat to human health. Such anti-platelet aggregation drugs as aspirin and clopidogrel are common drugs in clinic. However, along with the appearance of resistance and side effects of western anti-platelet aggregation drugs, anti-platelet aggregation traditional Chinese medicines promoting blood circulation to remove blood stasis have gradually become an important study orientation. Platelet is one of major participant in thrombosis, and plays an important role as a bioactive material in studies on traditional Chinese medicines promoting blood circulation to remove blood stasis, mainly involving two aspects--the evaluation for the anti-platelet aggregation activity of traditional Chinese medicines and the screening of their active components. This paper summarized the applications of platelets in studies on traditional Chinese medicines promoting blood circulation to remove blood stasis, so as to provide basis for further studies.
