Objective]Through finishing the information about oculopathy in“Acupuncture DaCheng”, analyze the treatment regulations, provide guidance for oculopathy treatment. [Method] Finishing the clause about oculopathy in“Acupuncture DaCheng”,counting numbers of points, frequency of each points, analyzing the characteristics of points, calculated out all points and the channel attribution. [Results] It is found that treatment of oculopathy inacupuncture Dachengof less points, commonly uses the extraordinary points, local points and meridians around eyes, and the characteristic of the dialectical treatment, in acupuncture treatment method at the same time attaches great importance to the use of moxibustion, and puts forward the whole set of gold needle couching. [Conclusion]Summing up the experiences of acupuncture treatment of oculopathy in“Dacheng”can provide reference for modern acupuncture of oculopathy in selection of points and ideal of treatment.

Objective To evaluate the application value of elastic index difference (EID) in identifying benign or malignancy masses of breast imaging reporting and data system (BI-RADS) 3-5.Methods Data of 193 lesions in 164 patients with ultrasonic diagnosed as BI-RADS 3-5 breast masses were retrospectively analyzed.All the cases were confirmed pathologically.The EID of masses and normal glands were measured with elastography quantitative analysis software.BIRADS 3-5 breast masses were diagnosed as malignant when EID≥2.5,which was the criteria for BI-RADS reclassification.ROC curve was drawn,and the area under the curve (AUC) was calculated.The diagnostic accuracy and AUC of malignant breast tumors with the methods of BI-RADS and BI-RADS combined with EID were compared.Results Taking pathological results as gold standard,the sensitivity,specificity,accuracy of BI-RADS in detecting malignant tumors were 96.00% (72/75),67.80% (80/118),78.76% (152/193),and those of BI-RADS combined with EID were 97.33% (73/ 75),83.05% (98/118),88.60% (171/193),respectively.The AUC of BI-RADS combined with EID (0.931) was higher than that of BI-RADS (0.875;Z=2.06,P<0.05).The statistical difference of accuracy was found between BI-RADS and BI-RADS combined with EID methods (x2 =15.21,P<0.05).Conclusion The combination of BI-RADS and EID is better than simple using BI-RADS in identifying benign or malignancy of breast tumors.

Objective To study the curative effect of internal thoracic arterial chemoembolization in the treatment of advanced lung cancer.Methods Internal thoracic artery was confirmed to be the main supplied artery by digital substraction angiography(DSA) in 8 cases with lung cancer. The internal thoracic artery was embolized by stainless steel coil below the supplied segment in order to avoid the normal vascular territory occlusion.Then iodized oil combined with Cis-Diaminedichloroplatinum(DDP) and mitomycin(MMC) were injected into the supplied segment slowly until blood flow stopped,at last,the gelfoam sponge sheet was inserted into this supplied segment to decrease the wash of iodized oil by blood flow.Results Clinical symptoms were improved obviously in all cases after therapy.CT scans showed that iodized oil accumulated in the tumor better four weeks after the chemoembolization. Conclusion For these cases with advanced lung cancer which the blood supply mainly by internal thoracic artery,it is necessary to perform chemoembolization.

AIM To investigate effect of urotensin Ⅱ (UⅡ)on proliferation of aort a smooth muscle cells (ASMC)of rat and study the signal transduction pathway o f it. METHODS In cultured ASMC of rat, UⅡ was used to stimulate proliferation of these cells and levels of [3H]-TdR incorporation were used to evaluate the speed of DNA synthesis, and different inhibitors were used to s tudy the action of different signal transduction pathway of mitogenic effect of UⅡ on VSMC. RESULTS 1×10-9~1×10-7 mol*L- 1 UⅡ caused marked concentration-dependent increasing of [3H]-TdR i ncor poration of ASMC. [3H]-TdR incorporation of 1×10-9,1×10-8 and 1×10-7 mol*L-1 UⅡ were 22%(P<0.05), 57%(P<0.01)and 65%(P<0.01)higher than control. Nicardipine, H7, W7 and PD98059 , which are inhibitors of calcium channel, PKC, CaM-PK and MAPK respectively, inhibited the effects of UⅡ obviously, with the inhibitory rate by 55%(P< 0.01), 27%(P<0.01),18%(P<0.05)and 16%(P<0.05)respectively . CONCLUSION UⅡ is a strong mitogen for VSMC and the mitogenic e ffect of UⅡ is probably mediated by Ca2+, PKC, CaM-PK and MAPK signal tr ansduction pathway.

Objective To investigate the hemodynamic changes of protosystemic collaterals before and after endoscopic treatment in patients with gastroesophageal varices using 64-row multidetector computed tomograghy portal venography (MDCTPV) so as to evaluate the efficacy of endoscopic treatment in patients with or without para-esoghageal varices and with or without nonvarices portosystemic collaterals before treatment. Methods Twenty-six patients with gastroesophageal varices, who underwent endoscopic variceal ligation (EVL) for esophageal varices and endoscopic N-butyl-2-cyanoacrylate injection (EBC) for gastric varices between Jan.2007 and Dec. 2009, were enrolled. Sixty four-row MDCT was used to examine the changes of portosystemic collaterals 1 week before and 12 months after endoscopic treatment. The reconstructed images of portosystemic collaterals before and after endoscopic treatment were evaluated. Results Excellent quality of portosystemic collateral vessels on CTPV were obtained in all patients. The mean diameter of left gastric vein decreased from (6.7±1.9) mm to (5.0±1.9) mm after endoscopic treatment,with significant difference (P< 0.05). There was no significant difference in outcomes between patients with or without para-esoghageal varices (80% vs 72.7%, P>0.05) and patients with or without non-varices portosystemic collaterals (82.4% vs 66.7% ,P>0.05). Conclusions Sixty fourrow MDCTPV may provide important information for option of endoscopic treatment and prognosis.

OBJECTIVE: To further probe the mechanisms of herbs for nourishing and smoothing the liver in reversing bile lithogenicity of guinea pig. METHODS: Sixty guinea pigs were divided randomly into control group (fed with normal diet, n=20), model group (fed with lithogenic diet, n=20) and treatment group (fed with lithogenic diet plus herbal medicine, n=20). After four-week feeding, the animals were sacrificed and sampled, the rates of gallstone formation in each group were estimated, and the total bile acid (TBA), total bilirubin (TBIL), conjugated bilirubin (CB), unconjugated bilirubin (UCB), and calcium ion in the bile were determined, and the different bilirubins were analyzed by HPLC. RESULTS: (1) The rate of gallstone formation was 5% in normal group, 81.25% in model group and 31.25% in treatment group (P<0.05). (2) The bile TBIL, CB, UCB and Ca(2+) were higher and the bile TBA was lower significantly in model group than that in the other two groups (P<0.05). (3) HPLC analysis revealed that MCB was higher and DCB was lower significantly in model group (P<0.01), and there were no significant differences of UCB and IPA among the three groups. (4) The percentages of MCB and UCB were much higher and the percentage of DCB was remarkably lower in model group (P<0.05). CONCLUSION: Herbs for nourishing and smoothing the liver can significantly reduce the rate of gallstone formation and has effect of reversing lithogenicity of bile in guinea pigs fed with lithogenic diet.

Objective: To study the effect of urotensin(U Ⅱ) on nitric oxide synthase(NOS)/nitric oxide(NO) system in rat aorta. Methods: The aortic slices were incubated in vitro. The medium nitrite content, vascular NOS activities and cGMP content were measured. Results: After incubation of aorta for 1.5-3.0 h, UⅡ(10-9-10-7 mol*L-1) increased nitrite production ( 14.8%-80.9%, P<0.01) in dose-dependent manner. U Ⅱ significantly stimulated the total NOS activities, mainly activated constitutive NOS (P<0.05 or P<0.01), however, the inducible NOS activities were not altered (P>0.05). Incubation of aortic slices with U Ⅱ (10-9-10-7 mol*L-1) increased vascular cGMP content in dose-dependent manner. Co-incubation vascular tissue with U Ⅱ and GN-L-nitro-arginine, an inhibitor of NOS, obviously inhibited the U Ⅱ-induced NOS activation, NO production and cGMP formation. Conclusion: The results suggest that U Ⅱ can activate the vascular NOS/NO pathway, increasing tissue NO production and cGMP content.
