Objective To observe the clinical efficacy of needle-knife therapy in treating allergic rhinitis. Method Sixty allergic rhinitis patients were randomized into a treatment group and a control group, 30 cases in each group. The treatment group was intervened by needle-knife therapy; the control group was given Azelastine hydrochloride nasal spray plus oral administration of Desloratadine, both twice a day. The intervention lasted for 4 weeks in both groups. The Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ) and symptoms scores were observed before and after the treatment, and the clinical efficacies were compared between the two groups. Result The markedly effective rate was 90.0% in the treatment group versus 66.7% in the control group, and the between-group difference was statistically significant (P<0.05). The RQLQ and symptoms scores were significantly changed after the intervention in both groups (P<0.05). After the treatment, the RQLQ and symptoms scores in the treatment group were significantly different from those in the control group (P<0.05). Conclusion Needle-knife therapy is safe and effective in treating allergic rhinitis.

Objective To introduce a better and quicker technique of transperitoneal laparoscopic ureterolithotomy. Methods 42 cases of ureterolithiasis (23 males and 19 females;mean age of 42.4 years,range from 16 to 63 years) were included.Of them 26 cases had calculi on the left side and 16 cases,on the right side.All the cases underwent laparoscopy through 3-port technique. Results The operations were successful in all of 42 cases.The mean operative time was 43 min (range,33 to 56 min).Blood loss was 20 to 50 ml.The postoperative hospital stay was 3 to 5 days.None experienced urinary leakage.During the follow-up of 12～18 months no ureteral stricture was found.The renal functions were improved. Conclusions Our experience indicates that appropriate trocar location,exactly checking of calculi,good D-J tube drainage and skillful intra-abdomenal suturing are the keys to perform laparoscopic ureterolithotomy quickly.

Objective To describe the new technique of transperitoneal laparoscopic dismembered pyeloplasty and to evaluate its clinical effect. Methods Of the 18 cases of ureteropelvic junction (UPJ) obstruction who underwent transperitoneal laparoscopic dismembered pyeloplasty,8 cases had severe hydronephrosis;7,intermediate;3,mild. Results Operations were all successful in 18 cases with the operating time being 100 to 210 min (mean,142 min) and the blood loss,40 to 200 ml.All the pores of puncture healed at phase 1;mean hospitalization was 7.4 d.Only 1 case had postoperative urine leakage.Follow-up of 3 to 12 months showed there was no stricture at UPJ and hydronephrosis was remitted (intermediate hydrops in 4 cases,mild in 7 and resolution in 7).The renal functions were improved. Conclusions Laparoscopic dismembered pyeloplasty is an effective and minimally invasive approach and can be used as an alternative to open surgery for UPJ obstruction.

Objective To investigate the inhibitory effect of ester catechin monomers-EGCG, GCG on the growth of human colon carcinoma cell line SW480 and its potential mechanism. Methods MTT assay, soft-agar colony formation test, Hoechst 33258 stain and flow cytometry analysis were used to determine the inhibitory effect of theasinesin(TS), and its monomers-EGCG, GCG on SW480 growth. Results EGCG, GCG and TS significantly inhibited the growth of human colon carcinoma cell line SW480 in dose-dependent manner, and their half inhibitory concentration (IC 50 ) was 108.88, 183.21, and 83.36?g?ml -1 , respectively. 24 hours after treatment with IC 50 of EGCG, GCG and TS, the colony formation rate of SW480 cells in the experimental group was obviously lower than that in the control group. Hoechst 33258 staining showed typical apoptotic features such as cell shrinkage, nuclear condensation and cell splinter in the experimental group. A subdiploid peak before G 0/G 1 phase in the experimental group was observed by flow cytometry. Conclusion In accord with TS, EGCG and GCG could inhibit the growth of colon carcinoma cell line SW480 cells, the mechanism of which may be related to inducing cell apoptosis.

ObjectiveTo observe the effect of two kinds of combination of acupuncture points on postoperative enteroparalysis.Methods96 patients with postoperative enteroparalysis were divided into the group A (n=44) and group B (n=52). The patients of the group A were treated with acupuncture on Mu points and lower-he point, while those of the group B on Back-shu points and distant lower-he point. The therapeutic effect of two groups was compared.ResultsThe two therapeutic methods had good effect, but the Back-shu points and distant lower-he points was superior to the Mu points and distant lower-he points ( P<0.05).ConclusionAcupuncture with combination of special points has better effect on postoperative enteroparalysis.

Objective To explore the effect of Tiam1 overexpression on the biological behaviors of human colorectal cancer cells ( CRC ) . Methods The human CRC lines under the established stable overexpression of Tiam1 were studied. Cell morphology was detected before and after transfection by commassie blue staining and scanning electron microscope. The proliferation in vitro of CRC was tested by cell cycle, MTT and plate colony formation assay, the migration and invasion ability of CRC was tested by Transwell assay. The proliferation ability in vivo was studied by induced subcutaneous tumors of nude mice. Results Compared with HT29/mock cells, HT29/Tiam1 cells formed as spindle, the pseudopodia increased and elongated. The proportion in S phase of HT29/Tiam1 was higher (t=19.546, P=0.000), the proliferation ability enhanced (F=177.125, P=0.000), colonies formation ratio increased ( t = 3 . 222 , P = 0 . 032 ) . The number of HT29/Tiam1 cells acrossing the microporous membrane (t = 4.832, P=0.001)and Matrigel(t=3.779, P = 0.005)all raised. On the fifteenth day, the growth deference between the HT29/Tiam1cells and HT29/mock cells in nude mice in vivo occurred. Till the thirtieth day, the size of the tumors in HT29/Tiam1 cell group were 2.3 times as large as that in HT29/mock cell group (F=53.040, P=0.002). Conclusions Tiam1 stable overexpression can promote the proliferation, migration and invasion ability of CRC which indicates its important role in carcinogenesis and evolution of colorectal cancer. Tiam1 may represent a new therapeutic target for colorectal cancer.

Objective To explore the clinical efficacy,adverse effect and prognosis of infliximab in treatment of the patients with juvenile idiopathic arthritis (JIA).Methods Thirty-two cases of infliximab-treated JIA patients and 30 cases of JIA control patients were investigated in this prospective study,and their tender joint count (TJC),swollen joint count (SJC),erythrocyte sedimentation rate (ESR),C-reactive protein (CRP),visual analog scale for general health (GH),disease activity score (DAS) 28,as well as adverse reactions of treatment and follow-up outcomes were analyzed.The infliximab-treated patients were intravenously infused with infliximab at the low dose of ＜ 5 mg/(kg · time) or the high dose of ≥ 5 mg/(kg · time) in 0,2nd,6th,14th,22nd,30th week.The JIA control patients were treated with conventional therapy.Results The treatment of infliximab ameliorated the TJC,SJC,ESR,CH,CRP and DAS28 of JIA patients.In the dynamical analysis of these clinical indexes of the infliximab-treated JIA patients,the index of SJC was found to fall firstly in the 2nd week,the indexes of TJC,ESR,CH and DAS28 were found to decline secondly at 6th week,the indexes of TJC,SJC,ESR,CRP and DAS28 continued dropping till 22nd week,and only the index of GH progressively declined to 30th week.The high-dose infliximab-treated group had lower levels of ESR,GH and CRP than the low-dose infliximab-treated group (t =2.14,3.04,2.33,P =0.04,0.01,0.04).But there were no statistical difference in TJC,SJC,DAS28 and the incidence of recent adverse reactions between the high and low infliximab dose groups.In the infliximab treated group,2 cases of patients (6.25％) failed in the therapy of infliximab;9 cases of patients (28.13％) continued therapy with infliximab to 46th-62nd week; 7 cases of patients (21.88％) stopped therapy with infliximab in the 30th week had good improvement of joint symptoms and inflammatory indexes; 14 cases of patients (43.75％) relapsed and retreated by infliximab after cease the first course of treatment; 1 case of patient died of severe chickenpox infection after therapy with infliximab was ceased.Conclusions Infliximab can alleviate the joint symptoms,inflammatory indexes and DAS28 of JIA patients,and is an effective and safe therapy for JIA patients in the short-term study.
