Objective To study the therapeutic effect and mechanism of Jiangtang Mixture combined with ear acupuncture for type 2 diabetic insulin resistance(IR).Methods Totally 120 cases of type 2 diabetic IR were randomly and equally divided into western medicine(Metformin) group,Chinese medicine (Jiangtang Mixture) group and Chinese medicine with ear acupuncture group.The treatment lasted for one month.The therapeutic effect,fasting plasma glucose(FPG),fasting insulin(FINS),postprandial 2 hours plasma glucose(P2hPG),hemoglobin A1c(HbA1c),blood fat,insulin Sensitivity index(ISI) and insulin resistance index(IRI) were observed before and after treatment.Results The total effective rate in Chinese medicine with ear acupuncture group was 92.5%,which was superior to those in Chinese medicine group (P

Objective To observe the effect of ligustrazine (TMP) on the expression of connective tissue growth factor (CTGF) and osteopontin (OPN) in the renal tubulointerstitium of diabetic nephropathy (DN) rats. Methods Wistar rats were used to establish the models through intraperitoneal injection of onedose streptozotocin (STZ) and nephrectomy. Rats were divided into 5 groups at random: model group, blank control group, Lotensin (1.7 mg? kg- 1? d- 1) group, of high-and lowdosage of TMP groups (150, 50 mg? kg- 1? d- 1). Except the rats in blank group and model group, the rats received corresponding medicines according to the experimental design for 12 weeks.Volume of urine protein within 24 hours was examined in the 4th, the 8th and the 12 th week, OPN mRNA expression in the renal tubulointerstitium was detected by RT- PCR and CTGF was detected by means of immunohistochemistry. Results Compared with normal group, the volume of 24 h urine protein rised obviously (P

Objective:To investigate the expression of antigens in Plasmodium yoelii sexual stage and transmission blocking effects of monoclonal antibodies(McAbs).Methods:Observing the effects of anti Pys25 McAb4 and anti Pys21 McAb10 on developmental course of parasites in mosquitoes by direct mosquito feeds on passively immunized P.yoelii infected mice and the expression of Pys21 and Pys25 from gametocytes to ookinetes in indicated culture times by IFA and Western blotting.Results:The transmission blocking activity of the anti Pys25 McAb4 was complete and more potent than that of the anti Pys21 McAb10.Both Pys25 and Pys21 were presented in whole developmental course from gametocytes to ookinetes.Furthermore,the expression of Pys25 appeared to be earlier than that of Pys21 on zygote surfact.Conclusion:Pys25 and Pys21 are target antigens of transmission blocking immunity and that anti Pys25 McAb4 has more significantly transmission blocking activity is related with the early stage expression of Pys25 on zygote surface.

Objective To evaluate the therapeutic efficacy of microendoscopic tubular retractor system (METRx) with a postmedial approach in the treatment of lumbar disc herniation. Methods A total of 290 patients with lumbar disc herniation were treated with METRx. The duration of follow-up ranged from 3 months to 33 months. Results According to the Nakai scale, 81% (235 cases) of the patients were evaluated as excellent, 13.4% (39 cases) as good, 4.8% (14cases) as fair and 0.7% (2 cases) as poor. Postoperative infection in intervertebral space was found in 2 cases. Conclusions METRx has a satisfactory short-term therapeutic efficacy in the treatment of lumbar disc herniation.

Objective To compare the curative effect between arthroscopic and open retrograde intramedullary interlocking nails in the treatment of femoral supracondylar fracture. Methods A total of 46 patients with femoral supracondylar fracture underwent the treatment by either arthroscopic (19 patients, Group A) or open (27 patients, Group B) retrograde intramedullary interlocking nails. Results The operation time, surgical blood loss and bone union time in the Group A were less than those in the Group B ( t =-4 193, -21 517 and -4 055, respectively; P =0 000). Follow-up for (10 3?3 6) months in the 46 patients revealed the results of therapy were, according to the Kolmert criteria, excellent in 15, good in 3, fair in 1 in the Group A while excellent in 7, good in 14, fair in 4 and poor in 2 in the Group B, without statistically significances between the two groups in the “good” or “excellent” rates (94 7% vs. 77 8%; ? 2 =1 345, P =0 246). Conclusions Use of arthroscopic retrograde intramedullary interlocking nails has advantages of shorter operating time, less blood loss and quicker bone union, benefiting the recovery of knee joint functions.

Objective To explore the typing,precaution and treatment of the bone cement leakage caused by percutaneous vertebroplasty(PVP).Methods PVP was performed in 38 cases(11 men and 27 women) with vertebral angioma and vertebral body compression fracture with osteoporosis chosen from November 2002.Results All the patients were followed up for 8 to 16 months and the effects were evaluated by the standards carried out by World Health Organization(WHO).The rate of complete response(CR) plus partial response(PR) was 100 percent.The patients with bone cement leakage by PVP were divided into 3 groups which underwent different remedial methods respectively.Conclusion The bone cement leakage could be prevented through the preoperative preparation,choosing the anaesthesia and scouting the whole operation.The patients with TypeⅠ,Ⅱ and Ⅲ_a needn't treatment,but those with type Ⅲ_b must accept open-operation.Vertebral eggshell technology with open vertebroplasty was effective on the treatment of the bone cement leakage with type Ⅲ_b caused by PVP.

Objective To evaluate the effect of arsenic trioxide (As2 O3 ) on the proliferation of human renal carcinoma cell line 786-O ,and to explore the changes of the PI3K-Akt signaling pathway .Methods Human renal cancer cells 786-O was cultured in 96-well plates ,and divided into the control group (n= 45 holes) and the experimental group (n= 45 holes) .After stimulation by 1 μM As2 O3 and saline ,the cells in 15 holes were collected at 0 ,12 ,and 24 h .BrdU assay was performed to quantify DNA synthesis to evaluate the cells proliferation ,the quantitative PCR was used to measure PI3K and Akt relative mRNA expression ,and Western blot was used to quantify the relative expression levels of of intracellular PI 3K and Akt .Results After 12 ,24 h of As2 O3 stimula-tion ,the amount of DNA synthesis in the observation group was gradually lower than that of the DNA synthesis at 0 h(P<0 .05) and significantly lower than that of the control group at 12 h and 24 h(P<0 .05) .At 0 ,12 ,24 h ,the relative expression level of in-tracellular PI3K and Akt mRNA and protein in the observation group had no significant difference (P>0 .05) ,and the relative ex-pression levels of PI3K and Akt mRNA and protein in the control group were increased as the proliferation was gradually increased . Conclusion As2 O3 inhibits human renal carcinoma cell line 786-O proliferation through inhibiting the PI3K-Akt transduction path-way ,and has potential clinical value for the treatment of kidney cancer .

Objective To evaluate the expression of MMP-2 and MMP-9 and their relation with tumor invasion and metastasis in transitional cell carcinoma of bladder (TCCB). Methods Immunohistochemistry of EliVision were respectively used to determine the MMP-2 and MMP-9 expression in tumor tissues of 46 patients with TCCB and 14 cases of control group which were screened quantitatively (3-5 cm of surrounding tumor) between August 2006 and August 2008. Results Expression of MMP-2 and MMP-9 in TCCB are obviously higher than the normal control group (P <0.01), expressions of MMP-2 and MMP-9 in level Ⅱ,Ⅲ are obviously higher than in level Ⅰ (P <0.01), but there was no significant relationship between high stage or level Ⅲ and low stage or level Ⅱ (P >0.05). Conclusion The positive expressions of MMP-2 and MMP-9 in tumor tissues correlated with the malignant degree, invasion and metastasis of TCCB, MMP-2, MMP-9 could be useful indicators for the assessment of prognosis of TCCB.
