Objective To investigate the clinical effect of ureteroscopic holmium laser lithotripsy for the treatment of ureteral calculus.Methods A total of 72 cases of ureteral calculus was treated with stone fragmentation from April to November 2004,by using the Lumenis VersaPulse PowerSuite 100W Holmium Laser system and the Circon ACMI Micro Ureteroscope.Under ureteroscopic visualization,the laser lithotrite was introduced to the stones,and holmium laser intraluminal stone fragmentation was carried out. Results The operation time was 14~83 min(mean,28 min).Three cases of fragmentation failure were due to upper ureteral stones migrating to the renal pelvis.The success rate of fragmentation on one session was 95.8%(69/72),which was 92.1%(35/38) for upper segment calculi and 100%(34/34) for middle-to-lower segment calculi.Intraoperative complications included 3 cases of ureteral perforation(4.2%),9 cases of stone migration(12.5%),and 72 cases of hematuria(100%).Postoperative complications included 45 cases of lumbago(62.5%),72 cases of hematuria(100%),and 5 cases of urinary tract infection(6.9%), without ureteral stricture.The kidney,ureter,and bladder(KUB) X-ray radiograph on the first postoperative day showed a stone-free rate of 86.1%(62/72),and the remaining residual stones were thoroughly expelled within following 2 weeks.The length of postoperative hospital stay was 2~5 d(mean,3 d).Re-examinations with B-ultrasonography or intravenous urography(IVU) at 3 months after operation in 46 cases revealed no ureteral stricture.Hydronephrosis subsided by 1.4?0.5 cm in 28 cases and completely disappeared in 21 cases.Conclusions Ureteroscopic holmium laser lithotripsy for treating ureteral calculus offers satisfactory clinical effects and low complication rates.

Objective To investigate the suppression effects of tumor suppressor gene p53 alone and apoptosis incombination with TNF-? in a hepatocellular carcinoma cell line Hep3B. Methods Hep3B cells were transfected with a wild-type p53 cDNA(wt-p53)and plain vector(pNeo) respectively. Then the cell were cultured for 12 hours, one of the transfected p53 groups was added TNF-?(20 ?g/ml). The expression of p53 was detected by immunological fluorescence assay. Determination of apoptosis was used by DNA fragmentation, TUNEL assay. Results Both a small dose TNF-? and wt-p53 can induce apoptosis more efficiently comparing with non-transfected cultures(P

Nonalcoholic fatty liver disease (NAFLD) has become the leading cause of abnormal liver enzymes in healthy individuals in China. Due to the complex pathogenesis of NAFLD, no consensus has been reached on the treatment of this disease. However, in recent years, more and more studies have put forward more pathogeneses and corresponding treatment recommendations. This article introduces and summarizes the research advances in the treatment of NAFLD, including lifestyle intervention, drug treatment, eradication of Helicobacter pylori, surgical treatment, regulation of intestinal microecology, and gene therapy.

Objective To detect the correlation of serum p53 antibody and p53 protein expression of cancer tissue in patients with colorectal cancer (CRC), and to evaluate if the serum p53 antibody might reflect the mutation of p53 gene in CRC. Methods One hundred and thirty-two patients with CRC and 36 patients with non-tumor disease were included in this prospective study. The presence of serum p53 antibody was determined by enzyme-linked immunosorbent assay (ELISA). Immunohistochemical analysis of tumors was performed to detect the accumulation of p53 protein. Results The positive rate of p53 antibody was 40.2% in patients with colorectal cancer and 2.9% in non-tumor patients,( P

AIM: To examine the effects of inhibition of Kupffer cell and splenectomy on intestinal endotoxemia and hepatic injury.

BACKGROUND: Eye acupuncture therapy is a technique used to adjust qi-blood circulation, relax muscles and tendons, and activate col aterals by acupuncture at the acupoints around the eye bal s and in the orbital border. This therapy has been widely used in the clinic because it exhibits remarkable therapeutic effects on many ischemic cerebrovascular diseases. However, the precise mechanism behind this therapy remains poorly understood. Neurotrophic factors are a protein family including neurotrophic factors and brain-derived neurotrophic factors that can regulate neuronal survival, development and functioning.
OBJECTIVE: To investigate the effects of eye acupuncture therapy on neurological function and nerve growth factor and brain-derived neurotrophic factor expression in the brain tissue of rat models of cerebral ischemia/reperfusion injury.
METHODS: Fifty-four male Sprague-Dawley rats were randomly divided into three groups with 18 rats per group: sham-operated, model and eye acupuncture therapy groups. Rat models of middle cerebral artery occlusion were established by the intraluminal suture method in the model and eye acupuncture therapy groups. Eye acupuncture was performed at the fol owing acupoints liver area, upper-jiao area, lower-jiao area and kidney area located at the internal orbital margin at 2 hours after cerebral ischemia/reperfusion injury. Rat neurological function was evaluated at 3, 7, and 14 days after injury. Nerve growth factor and brain-derived neurotrophic factor expression in the rat brain tissue was detected using immunohistochemical staining method at 1 and 2 weeks after treatment. Cerebral infarct size was determined using TTC staining at 2 weeks after treatment.
RESULTS AND CONCLUSION: (1) At 1 and 2 weeks after injury, nerve growth factor and brain-derived neurotrophic factor expression was significantly greater in the eye acupuncture therapy group than in the model group (P < 0.05), but nerve growth factor and brain-derived neurotrophic factor expression in the eye acupuncture therapy group was decreased at 2 weeks after injury compared to that at 1 week after injury. (2) At 7 and 14 days after treatment, neurological function scores in the eye acupuncture therapy group were significantly lowered, and there was significant difference between eye acupuncture therapy and model groups (P < 0.05), but they were significantly higher than those in the sham-operated group (P< 0.05). (3) At 2 weeks after treatment, cerebral infarct size was significantly greater in the eye acupuncture therapy and model groups than in the sham-operated group (P < 0.01), and it was significantly smal er in the eye acupuncture therapy group than in the model group (P < 0.05). (4)These results indicate that eye acupuncture therapy shows neuroprotective effects on ischemic cerebral injury by increasing nerve growth factor and brain-derived neurotrophic factor expression, improving neurological function, and reducing cerebral infarct size.

Objective To investigate the association between single nucleotide polymorphisms (SNPs) of ATP-binding cassette B1 (ABCB1),ATP-binding cassette C2 (ABCC2) and solute carrier organic anion transporter 1B1 (SLCO1 B1) genes with high dose methotrexate (HDMTX)-induced toxicity in children with acute lymphoblastic leukemia (ALL).Methods This study was designed as a casecontrol.From September of 2005 to December of 2011,the blood samples were randomly collected from 142ALL patients from Nanjing Children's Hospital,Enzyme-multiplied immunoassay technique (EMIT) was used to measure the plasma concentration of MTX,Seven SNPs in ABCB1 (rs1045642,rs2032582,rs1128503),ABCC2 (rs717620,rs2273697) and SLCO1 B1 (rs4149081,rs11045879) genes were detected by polymerase chain reaction-ligase detection reaction (PCR-LDR).Results A significantly increased risk of MTX-induced toxicity was observed in patients with MTX elimination delay (OR ＝ 2.828,95％ CI:1.217-6.571,P ＜ 0.05).Two SNPs in SLCO1B1,rs4149081 and rs11045879 were linkage disequilibrium (LD) with each other (R2 =0.979,P ＜ 0.05).Multivariate analysis revealed that individuals with SLCO1B1 rs4149081 AA genotype or SLCO1B1 rs11045879 CC genotype showed increased incidence of MTX elimination delay (OR =4.41,95％ CI:1.537-12.654,P =0.042),and the two genotypes were also associated with significantly increased risk of MTX-induced toxicity (OR =4.118,95％ CI:1.135-14.944,P =0.022).No association of MTX elimination delay or MTX-induced toxicity with the other SNPs analyzed was found.Conclusions SLCO1B1 rs4149081 AA or SLCO1B1 rs11045879 CC genotypes might be a risk factor for the susceptibility to MTX-induced toxicity in children with ALL.
