Objective To evaluate a modified liver hanging maneuver(retrohepatic tunnel of the IVC) in patients undergoing hemihepatectomy.Methods Twenty-four patients undergoing hemihepatectomy were divided into two groups:modified liver hanging maneuver group(n=12)and Pringle's maneuver group(n=12).The amount of intraoperative bleeding,operation time,postoperative liver function,liver function recovery and complications were compared between the two groups.Reset All operation were performed successfully and there were no difference in the time of operation etween the two groups.There was a difierence in the amount of mean intraoperative blood loss between the two groups.It was(160±40)ml in liver hanging group and(560±120)ml in Pringle's group(P＜0.01).Liver function recovery measured on postoperative day 3 and day 7 was better in liver hanging groupthan that in Pringle's group(P＜0.01).The volume of postoperative peritoneal serous fluid dranage was significantly less in liver hanging group(P＜0.01).Conclusion The modified liver hanging maneuver is useful for hemihepatectomy.

Objective Although vascular endothelial growth factor(VEGF)is a primary mediaor in diabetic retinopathy(DR).VEGF inhibition alone is insufficient for preventing retinal neovascularization.Some studies showed that erythropoietin(EPO)is a potent retinal angiogenic factor of independent of VEGF in DR.The present study is to investigate the effect of high glucose on the expression of mRNA and protein of the erythropoietin receptor(EPOR)in cultured human umbilical vein endothelial cells(UVECs)in vitro.MethodsHuman UVECs from the cell center of the hospital were cultured in vitro and passaged in DMEM containing 10% neonatal bovine serum with 22mmol/L of glucose for 12,24,48 and 72 hours in the experimental group.Cells cultured in 5.5mmol/L glucose were used as control group Ⅰ and mannitol + 22mmol/L of glucose(isotope)as control group Ⅱ.The expression of EPOR mRNA in Human UVECs were detected by semi-quantitative reverse transcriptase(RT)-polymerase chain reaction(PCR)and detected at A_(260mm)/A_(280mm).The PCR product was calculated as the A value of EPOR mRNA amplification/the A value of GAPDH mRNA amplification.The expression of EPOR protein in Human UVECs was detected by immunocytochemistry.ResultsThe A_(260mm)/A_(280mm) value of EPOR mRNA receptor expression was 0.32±0.02 in the 5.5mmol/L glucose group,and 0.34±0.02 in the mannitol+22mmol/L glucose group(P>0.05).In 12 hours,24 hours and 72 hours after the experiment,the A260mm/A280mm value of EPOR mRNA was 0.82±0.01,0.96±0.02 and 1.02±0.01,respectively,indicating a significant increase in comparison with the 5.5mmol/L glucose group.The expression of Human UVECs protein was gradually increased with passage in the experimental group.Expression of Human UVECs protein was stronger in various time points in the 22mmol/L glucose group than in the 5.5mmol/L glucose group.ConclusionHigh glucose elevates the expression of EPOR mRNA and protein in Human UVECs in a time-dependent manner.The effect of high glucose(22mmol/L glucose)on the expression of EPOR mRNA and protein in Human UVECs is not related to osmotic pressure.

Objective To evaluate the clinical applications and limitations of helical CT virtual cystoscopy (CTVC).Methods CTVC was performed in 36 patients suspected bladder diseases, all cases were confirmed by conventional cystoscopy and pathology. CTVC images were generated from the volumetric data of the excretory phase using helical CT. The results were then compared with the findings of axial images and conventional cystoscopy in a double-blinded manner. Results CTVC could clearly display the normal anatomic structures of bladder, 11 ureteric orifices were visualized at CTVC in 7 of 8 normal bladders. The location, size, numbers, configuration and extension of lesions showed on CTVC were corresponded well with that of conventional cystoscopy. The sensitivity to vesical carcinoma was 94.7%,2 tumors smaller than 5 mm depicted on CTVC images were not seen on the axial images, whereas areas of wall thickening and extravesical invasions were more readily appreciated on axial and MPR images. There was 1 false lesions detected on CTVC images. Conclusion CTVC has proved to be a noninvasive and reliable technique in the detection and diagnosis of bladder lesions, but the optimal evaluation requires adequate bladder filling with contrast medium, and should combine with the interpretation of axial and MPR images.

Objective To investigate the apoptosis of articular chondrocyte and the expression of Bcl-2, Bax, Fas and iNos in articular cartilage with Kashin-Beck disease(KBD) in order to understand the pathogenesis of chondronecrosis in KBD. Methods The collected samples of human articular cartilage were divided into two groups: control group (15 samples from 15 cases), KBD group (15 samples from 15 cases). KBD patients were diagnosed by "Pathological Criteria to Diagnose KBD in China". Chondrocyte apoptosis was detected by TUNEL staining, and the Bcl-2, Bax, Fas and iNos positive articular chondrocytes were stained by the B-SA of immunohistochemistry. Articular cartilage was classified three zones and the positive rate were counted by light microscope for cytoplasimic staining by polyclonal antibodies of Bcl-2, Bax, Fas and iNos and apoptotic chondrocytes by TUNEL. Results ① The percentage of positive apoptotic chondrocytes stained by TUNEL in the middle zone of articular cartilage from the KBD-children group(33.60±2.71%) was higher than that of the control (1.33±0.41% t=11.59, g=28, P<0.01). ②The percentage of chondrocytes staining for Bcl-2, Bax, Fas and iNos among the upper and the middle zone in KBD group were significantly higher than that of the control (t=11.75-18.65, g=14, P<0.01); the remarkable difference in the expression of Bcl-2, Bax, Fas and iNos among the upper, the middle and the deep zones was also seen in KBD articular cartilage (F=73.49-114.42, g=42, P<0.01), and staining for Bcl-2, Bax, Fas and iNos in KBD children was prominent in the upper zone(41.93±12.26%, 45.60±15.78%, 53.60±16.49%, 45.47±14.02%) and the middle zone(14.93±3.50%, 13.87±4.32%, 23.27±4.83%, 21.67±6.82%)of articular cartilage, respectively. Conclusion The chondrocyte apoptosis and the present of Bcl-2, Bax, Fas and iNos positive chondrocytes in articular cartilage of children with KBD were significantly higher than that of the control.

Objective To investigate and analyze the preventive effect of boron on the cartilage damage in rats with intake excessive fluoride. Methods Fifty-ix Sprague-Dawley rats were divided into the control group (C, intake distilled water), the excessive fluoride dose group (EF, intake distilled water with 100 ppm F-) and the boron prevention group (P, intake distilled water with 100 ppm F- as well as the supplemental boron dietary). 3 to 5 months later, fluorine contents in serum, RNA contents in costal cartilage were assayed. The morphological changes in tibia growth plate cartilage (GPC) in rats were observed. Results Although exposed to the same dose of fluoride, the fluorine contents in serum in rats of P group decreased notably compared with those of EF group, the damage of tibia GPC under optical and electron microscope lessened significantly, and RNA contents in costal cartilage increased obviously in the 3rd month. Conclusion Boron added could decrease the fluorine level in the body and relieve the toxic symptom of excess fluoride, and thus boron has a preventive effect on skeletal fluorosis.

Objective To study effects of salmon calcitonin and Heng Gu bone healing reagent on vertebral osteoporotic fracture(OPF).Methods From Nov.2007 to Dec.2009,82 cases of vertebral OPF were treated.These cases were randomly divided into treatment group and control group.The treatment group(42 cascs)were treated with salmon calcitonin and Heng Gu bone healing reagent.The control group(40 cases)received salmon calcitonin only.Pain relief of the 2 groups wag compared.Results Before treatment,the 82 patients were scored 6-9 points by visual analogue scales(VAS)and pain scores of the 2 groups were similar (P>0.05).3 days,5 days,8 days and 15 days after treatment,VAS scores of the 2 groups were significantly different(P<0.01).Compared to the control group,the treatment group had pain relief in shorter time and their bone mineral density Was better showed by the 3-month-later review.Conclusion The combination therapy of salmon calcitonin and Heng Gu bone healing reagent in treating vertebral OPF has better effect of pain relief and bone formation,which is a safe and effective method.

Objective:To observe the clinical efficacy of acupuncture at abdomen acupoints plus tuina for lumbar intervertebral disc herniation (LIDH).Methods:A total of 70 patients with LIDH were randomized into an observation group and a control group,with 35 cases in each group.The observation group was treated with acupuncture at abdomen acupoints plus tuina,while the control group was treated only with tuina treatment.The clinical efficacy was observed after one course of treatment.Results:The cure rate and the total effective rate of the observation group were 83.3％ and 96.7％,respectively.The cure rate and the total effective rate of the control group were 39.4％ and 78.8％,respectively.There were significant differences in the cured rate and the total effective rate between the two groups (both P＜0.05).There was no significant difference in Japanese Orthopedic Association (JOA) score between the two groups before treatment (P＞0.05).After treatment,the JOA scores of both groups increased significantly,and the intra-group differences were statistically significant (both P＜0.05);the JOA score of the observation group was significantly higher than that of the control group (P＜0.05).Conclusion:Acupuncture at abdomen acupoints plus tuina has a better therapeutic effect than tuina alone in the treatment of LIDH.
