Meanwhile, the expression levels of cleaved caspase-3 was up-regulated.The structure of F-actin was destroyed. Conclusions ATRA could induce the apoptosis of DU145 cell mediated by caspase-3 and lead to the destroy of F-actin’s structure.

Objective To observe the clinical efficacy of the Mingmen eight array massage combined with compound lysine hydrochloride and zinc gluconate granules for the treatment of infantile diarrhea. Methods Totally 120 children with diarrhea met the inclusion criteria were divided into the treatment group, Western medicine group, and general massage group by random number table method, 40 cases in each group. All 3 groups were given dietary guidance and did moderate exercise. Western medicine group was administered orally for compound lysine hydrochloride and zinc gluconate granules, two bags per day for the aged 1–10, three bags per day for the aged >10. Treatment group was given the Mingmen eight array massage therapy based on Western medicine. General massage group received conventional massage therapy based on Western medicine, with four weeks as treatment course. 3 groups of patients were observed before and after treatment for salivary amylase, blood zinc value, urine D-xylose absorption and excretion test, TCM symptom score, and clinical efficacy were evaluated. Results There was statistical significance in the salivary amylase, blood zinc value, and urinary D-xylose absorption and excretion rate between before and after t reatment(P<0.05); after treatment, treatment group showed higher salivary amylase, blood zinc value, and urinary D- xylose absorption and excretion rate than the Western medicine group and general massage group (P<0.05); scores of diarrhea, loose stool, lassitude, lusterless complexion, and appetite reduction decreased compared with before treatment (P<0.05); after treatment, all integrals of treatment group were lower than Western medicine group and general massage group (P<0.05). The total effective rates of the treatment group, Western medicine group and general massage group were 92.50％ (37/40), 72.50％ (29/40), and 75％ (30/40) respectively. There was statistical significance among the three groups (P<0.05). Conclusion Mingmen eight array massage combined with compound lysine hydrochloride and zinc gluconic granules can effectively alleviate the clinical symptoms of patients with infantile diarrhea, and improve the level of laboratory parameters.

Aim To observe the effect of gypenosides ( GP) on the expression of receptor for advanced gly-cated endproducts ( RAGE ) and transforming growth factor-β1 ( TGF-β1 ) in human mesangial cells( HMCs) induced by AGEs. Methods HMCs were cultured in DMEM of low glucose containing 15% fetal bovine ser-um in vitro, which were divided into four groups: the normal group, model group, GP group and positive control group. In addition to the normal group, the other groups were stimulated by AGEs ( 200 mg · L-1 );furthermore, GP group was intervened with dif-ferent concentrations(25,75,175 mg·L-1) of GP, while control group was given 10 mmol · L-1 of amin-oguanidine hydrochloride. The expression of RAGE and TGF-β1 protein of each group was detected by Western blot; the expression of RAGE and TGF-β1 mRNA of each group was detected by RT-PCR. Re-sults The expression of RAGE, TGF-β1 protein and mRNA in HMCs induced by AGEs in the model group was significantly higher than that of the normal group ( P<0. 01 );compared with the positive control group ( P<0. 01 ) , GP could obviously reduce the expression of RAGE, TGF-β1 protein and mRNA in a dose-de-pendent manner. Conclusion GP can reduce the ex-pression of RAGE in HMCs induced by AGEs, block AGEs-RAGE signaling pathway and decrease the ex-pression of the downstream factor TGF-β1 , therefore, it plays the role in the resistance of rennal fibrosis in DN.

AIM To study the inhibitory effect of the cytotoxin (CTX) from guangxi cobra venom on human nasopharyngeal cancer cell (CNE) and other tumons cells. METHODS The cytotoxin was isolated and purified from Guangxi cobra venom by successive chromatography on Sephadex G-50 and CM Sepharose CL-6B columns. Its cytotoxic effects and does-effect relationship on human tumors cell lines were examined by MTT assay. RESULTS The inhibitory effects of CTX CM-5 on CNE, human ovarian carcinoma cell (Ho8990), uterus cervical carcinoma cell (HELA) and lymphoma (YAC) cell lines showed a definite does-effect relationship. The IC 50 (48 h in cubation) was 1.84, 2.59, 1.84 and 0.75 mg?L -1 respctively. The inhibitory effects of CTX CM-5 on CNE increased with time. The IC 50 (3 h and 24 h cubation) was 4.78 and 1.04 mg?L -1 respctively. CONCLUSION CTX from Guangxi cobra venom exhibites strong suppressive effect on cultured tumor cells line in vitro.

Vascular complications after liver transplantation can seriously threaten the survival of patients.In the preoperative assessment and postoperative monitoring of patients' vascular conditions,although the digital subtraction angiography (DSA) is the golden standard for vascular lesion diagnosis,but not the first choice due to traumatic lesions.In some clinical circumstances,DSA can only be used when Doppler ultrasound,spiral CT,and MRI are not applicable,and in most cases DSA is used for treatment rather than diagnosis.This article reviewed the current interventional treatment of vascular complications to stress the important role of DSA in diagnosis and treatment of related complications after liver transplantation.

Objective To discuss role of double intramedullary nail in the treatment of floating knee injuries under minimally invasive surgery.Methods From July 2006 to July 2010,23 patients with floating knee injuries ( Fraser type Ⅰ ) were fixed with tibial intramedullary nail and femoral retrograde intramedullary nail assisted by minimally invasive method such as portable bracket,AO large distractor and Schanz screw.The postoperative continuous passive motion (CPM) was performed for functional exercises of the knee.Results The operation lasted for average 95 minutes ( range,70-160 minutes),with average blood loss of 260 ml ( range,100-600 ml).All patients were followed up for average 11 months (range,7-35 months).According to assessment systems of Karlstrom and Olerud,the clinical results were excellent in 17 patients,good in 4 and fair in 2,with excellence rate of 91％.Conclusions Combined with the methods of portable bracket of lower limb,AO large distractor and Schanz screw,the intramedullary nail is much convenient and minimally invasive for the floating knee injuries.

ObjectiveTo analyze the association of HLA-DQA1 gene polymorphism with persistent Chlamydia trachomatis genital infection.Methods Blood samples were collected from 80 patients with persistent genital Chlamydial infection,80 patients with common genital Chlamydial infection(who tested negative for Chlamydia trachomatis after one course of standard systemic treatment) and 80 normal human controls.HLA-DQA1 alleles were genotyped by PCR followed by gene sequencing.ResultsThe frequency of HLA-DQA1*0102 allele and HLA-DQA1*0501 allele was 22.5％ and 5.0％ respectively in patients with persistent genital Chlamydial infection,5％ and 20％ respectively in those with common genital Chlamydial infection,2.5％ and 17.5％ respectively in normal human controls.Compared with the patients with common genital Chlamydial infection and controls,the patients with persistent genital Chlamydial infection had a higher frequency of HLA-DQA1*0102(x2 =14.6286,P ＜ 0.001 ),but a lower frequency of DQA1*0501 (x2 =6.2598,P ＜ 0.05).ConclusionsHLA-DQA1*0102 allele may be a susceptible gene or closely linked with the susceptible genes of persistent genital Chlamydial infection.HLA-DQA1*0501 allele may have protective effects against persistent genital Chlamydial infection.
