OBJECTIVETo observe the immediate antihypertensive effect of guasha combined with bleeding therapy for mild (grade I) hypertension.

METHODSThirty patients with mild (grade I) hypertension and 30 cases with normal blood pressure were compared. Areas and acupoints in governor vessel, meridian of foot-taiyang, meridian of hand-yangming and meridian of foot-yangming were scraped for 3 times, which was followed by bleeding therapy. The blood pressures after each guasha and bleeding therapy were recorded as well as the skin temperature in Dazhui (GV 14) after each guasha. The treatment was given once a week and totally 4 treatments were given.

RESULTSThere were significant antihypertensive effects after the first guasha, the second guasha and the third guasha and bleeding therapy (all P<0.01), in which guasha combined with bleeding therapy had the most significant antihypertensive effect (P<0.01). The skin temperature in Dazhui (GV 14) was obviously increased after three times of guasha (all P<0.01).

CONCLUSIONGuasha or combined with bleeding therapy has better antihypertensive effect for mild hypertension, which is likely to be related with warming stimulation on meridians and acupoints.

The image guided radio therapy (IGRT) Imaging System based on cone-beam computer tomography (CBCT) can reach the goal of improving the accuracy of the radiotherapy. However, because the clinical registration between CBCT images and Planning CT images is carried out manually, it inevitably reduces radiation positioning accuracy to some extent. To tackle the problem, we proposed a new feature vector selection method for the CBCT image elastic registration in the framework of hierarchical attribute matching mechanism for elastic registration (HAMMER) algorithm. We analyzed the characteristics of HAMMER algorithm and used Canny operator which has a better edge detection and positioning performance to replace the noise-sensitive gradient amplitude. Therefore, we used a new attribute vector, which consisted of the intensity, Laplacian of the Gaussian and Canny operator, to ex tract the image feature points in CBCT and planning CT images. We also presented an adaptive feature-point selection method and the choice criteria of attribute vector weights. Experimental results showed that the new feature vector effectively avoided the noise interference resulted from scattering lines in CBCT images to improve registration accuracy, and it also decreased the required feature point numbers and reduced the computation redundancy, so that it provided a new approach for the clinical elastic registration of CBCT and Planning CT rapidly and accurately.

Objective To evaluate the accuracy and sensitivity of three techniques in the diagnosis of renal diseases following multiple myeloma. Methods 41 serum samples from the kidney-damaged patients with multiple myeloma and 36 from the control group with general renal diseases were detected by quantitative analysis of immunoglobulins, serum protein electrophoresis and serum Immunofixation Electrophoresis. The accuracy and sensitivity of the three techniques were analysed by Two-way ANOVA and Multiple Comparisons of the check-out rate of monoclonal immunoglobulin. Results No monoclonal components were checked out by quantitative analysis of immunoglobulins. The checkout rate of IgG and IgM myelomas were 100% by serum protein electrophoresis, which had application limit on other types of myelomas. Whereas all secretarial myelomas could be diagnosed and typied by Immunofixation Electrophoresis, the sensitivity and accuracy was 100%, there was no false positive in the control group. Comparing with quantitative analysis of immunoglobulins and serum protein electrophoresis, serum Immunofixation electrophoresis had higher sensitivity and accuracy in diagnosis of renal diseases following multiple myeloma ( P

Objective:To investigate the effects of endostatin on Ang-2/Tie-2 system in ectopic lesion.Methods:Thirty mice of endometriosis model (EM) were established by peritoneum planted.After 1 week of transplantation,model mice were randomly divided into three groups including rAAV2-hEndostatin-EGFP group (n=20),rAAV2-EGFP group (n=20)and PBS control group (n=20).The histology changes were examined in the three groups.The expressions of Ang-2 and Tie-2 Were examined by immunohistochemistry.Results:The EM model mice were established suecessfully.The gland proliferation was obvious in the two control groups.The mesenchymal blood vessel was rich.But there were gland atrophy and blood vessel reducing in endostatin group.There were expressions of Ang-2 and Tie-2 in the cytoplasm of endothelium,epithelial glands and stroma.The positive rate of Ang-2 expression was 40%in endostatin group,much lower than that in other two groups(75%and 80%,P＜0.05).The positive rate of Tie-2 expression was 45%in endostatin group,which was also lower than that in other two groups(80%and 85%,P＜O.05).Conclusion:Endostatin can effectively interfere angiogenesis process of Ang-2/Tie-2,which lays the foundation for clinical therapy by anti-angiogenesis.

Objective To investigate the effects of diclofenac sodium suppositories on emergence agitation after sevoflurane maintenance in children undergoing adenotonsilleetomy. Methods Forty-five patients selected for adenotonsillectomy were randomly divided into three groups (n=15). Patients in group 1 were given diclofenac sodium suppositories 12.5 mg right after intubation, those in group 2 were given diclofenac sodium suppositories 12.5 mg immediately after operation, while those in control group were not treated with diclofenac sodium suppositories before or after operation. The extubation time and time spent in post-anesthctic ICU (PACU) were recorded, the modified Aldrete score and pain score were assessed after entrance into PACU, and pediatric anesthesia emergence delirium (PAED) scale was administered 10, 20 and 30 rain after entrance into PACU. Results There was no significant difference in extubation time and time spent in PACU among three groups(P>0.05). Ten minutes after entrance into PACU, the PAED score of group 1 was significantly lower than those of group 2 and control group(P<0.05), while there was no significant difference between the latter two groups(P>0.05). Twenty and thirty minutes after entrance into PACU, the PAED scores of group 1 and group 2 were significantly lower than that of control group(P<0.05). There was no significant difference in the modified Aldrete score right after entrance into PACU among three groups. The pain scores of group 1 and group 2 were signifiantly lower than that of control group(P< 0.05). Conclusion Diclofenac sodium suppositories can decrease the incidence and severity of emergence agitation after sevoflurane maintenance in children undergoing adenotonsillectomy.

Objective To explore effects of parents exposure to TBT on blood routine of F1 generation mice. Methods 80 mice including 40 males and 40 females, were randomly divided into control groups (CK) , low dose groups (LTBT), middle dose groups (MTBT) and high dose groups (HTBT).They were given dose of TBT (0,0.2,2, 20μg/kg) every day.The experiment lasted 45 days.At 60 days, one female and one male of the same concentration were bred in the same cage according to 1∶1.At postnatal day 60, blood was collected for the determination of blood routine.

OBJECTIVETo study the regulatory effect of Yishou Tiaozhi Tablet (YSTZT) on blood lipids in patients with primary hyperlipidemia.

METHODSOne hundred and sixty-eight patients with primary hyperlipidemia were randomly divided into two groups. The treated group was treated with YSTZT 4 tablets 3 times a day, and the control group was treated with Zocor by oral taking 1 tablet before sleep every evening. The therapeutic course for both groups was 60 days. The effect in regulating blood lipids in patients was observed.

RESULTSThe levels of total cholesterol (TC), triglyceride (TG), low density lipoprotein cholesterol (LDL-C), arteriosclerosis index (AI), apo-lipoprotein B (apoB), TC/HDL-C lowered and apoA/apoB ratio increased obviously in the treated group. As compared the effects between the two groups, the lowering of TC, AI and apoB in the two groups were similar (P > 0.05), effect of YSTZT in lowering TG was superior but in lowering of LDL-C was inferior to those of Zocor respectively (all P < 0.01). The effect of both remedies in elevating HDL-C was not satisfactory. The total effective rate of YSTZT was 91.9%, its individual effects were similar to those of SJZ respectively except in lowering TG and raising HDL-C. The adverse reaction occurred in YSTZT treatment course was mild without any influence on the medication.

CONCLUSIONYSTZT had definite regulatory effect on the blood lipids and lipoproteins in patients with hyperlipidemia.

Objective To explore the clinicopathological features of IgA nephrolpathy associated with malignant hypertension (IgAN-MHT) and to analyze their correlation with renal vascular lesions. Methods Twenty-nine patients of IgAN-MHT were screened from 2000 biopsy-proven eases with primary IgA nephropathy (IgAN) in our department from April 1997 to May 2007. Data of clinicopathology and follow-up of these 29 patients were collected. Semi- quantitative analysis was performed to evaluate the pathological changes. Inner lumen, outer lumen, intimal thickness, tunica media-to-internal lumen ratio of 436 arterioles, 124 interlobular arteries and 5 arcuate arteries were measured. The primary endpeint was the composite of a doubling of serum creatinine level and ESRD. Correlations of renal vascular lesions with clinical manifestation, pathological change and prognosis were examined by Spearman and Cox methods. Results 1.5% of all the IgAN patients presented malignant hypertension. The common clinical features were renal failure (100%), hyperurieacidemia (62.7%) and hypertriglyceridemia (51.7%). The average amount of urine protein excretion was 2.8 g/d. The common pathological changes were moderate mesangial proliferation, severe global sclerosis, severe interstitial inflammation and severe interstitial- tubular fibrosis. The small arteries (arcuate arteries and interlobular arteries) and arterioles (afferent arterioles) were both involved in IgAN-MHT. The characteristic lesions of intrarenal arteries included vascular occlusion, media thickening, proliferative endarteritis (onionskin lesion, musculomucoid intimal hyperplasia), hyaline arteriosclerosis, but mainly vascular occlusion (86.2%). The arteriole lesion was negatively correlated with age and total protein level; vascular occlusion was positively correlated with uric acid level. The average foUow-up period was 21.1 months. Forteen patients reached the endpoint. The arteriole lesion was the main independent risk factor for the progression of IgAN-MHT (RR=10.21, 95%CI=1.16～89.67). Conclusions The main clinical feature of IgAN-MHT is renal failure. The main histological feature of intrarenal vascular lesions is occludes arterioles. Arteriole lesion is the main independent risk factor for the progression of IgAN-MHT.

OBJECTIVE: To analyze the subjective and objective burden given by patients with mental disorder in a family, and probe into the family interference therapy model.METHODS: The method of looking up documentation was used to investigate the information about the family of patients with mental disorder. The study is to mainly investigate the burden status of Chinese family, observe the effect of social consensus on the family of the patients with mental disorder, detail explain and analyze the different burden and needs of the family of the patients with mental disorder in urban and rural area. Ant the same time, the family interference therapy model was introduced to apply in China.RESULTS: Objective family burden mainly includes economic burden and physical burden induced by earing for patients. Subjective burden are mainly mental crucifixion of the family member given by the patients with mental disorder; even severe mental injury. Social stigma can bring more serious subject burden to the Chinese family. Mental health services center reduces the depression of the family, and single-family session was used to further treat mental weakness and internal conflict of each family. The object to establish family support group was mainly to share the education and experience.CONCLUSION: Family members of the patients with mental disorder bear the subjective and objective burden. Family interference therapy can postpone the relapse of mental disorder, also improve the status of the patient in family and the harmonious degree of the whole family.

Objective To evaluate the dose distribution of target volume and normal tissues in forward intensity modulated radiotherapy (fIMRT) and inverse intensity modulated radiotherapy (iIMRT) modes for breast cancer after radical mastectomy.Methods Both fIMRT and iIMRT plans were developed for 10 patients with breast cancer after radical mastectomy.On each patient's CT images the supraclavicular area, chest wall, and internal mammary area were delineated.The prescription dose was 50 Gyin 25fractions.In the fIMRT plan X-ray irradiation at the dose of 6 MV was adopted for the supraclavicular and the chest wall areas and electron irradiation at the dose of 9 - 12 MeV was adopted for the internal mammary area, and the doses of cold and hot spots were adjusted according to the fitting doses of these 3 regions.In the iIMRT plan the supraclavicular area, chest wall, and internal mammary area were taken asa whole target, 6 MV X-rays was used, and inverse optimal design was performed.The dose distribution oftarget volume and normal tissues, conformal index (CI) , and heterogeneous index (HI) , and acceleratormonitor unit (MU) were analyzed using dose-volume histogram (DVH)for the two intensity modulated modes.Results The maximum dose of PTV of the iIMRT plan was significantly lower than that of the fIMRT plan(t = -3.23,P ＜0.05), the minimum dose and V95% of PTV of the iIMRT were significantly higher than those of the fIMRT plan(t = 4.08, -2.69, both P ＜0.05).The CI level of the iIMRT plan was significantly higher than that of the fIMRT plan and the HI level of the iIMRT plan was significantly lower than that of the fIMRT plan (t = -3.13, 2.74, both P ＜0.05).There were not significant differences in V10, V20, V25, V30, and Dmean of the ipsilateral lung between these 2 groups.However, the V15 of ipsilateral lung of the iIMRT group was significantly lower by 4.2% than that of the fIMRT group (t= 3.2, P ＜ 0.05).There were not significant differences in the mean dose (Dmean) and V30 of heart, and Dmean of contralateral lung and contralateral breast between these 2 groups.Conclusions Compared with fIMRT, the iIMRT plan results in more PTV coverage, higher conformity index, and more homogeneous dose distribution, with lower dose upon the lung at the affected side, and better protection of the contralateral lung, heart, and breast.
