Objective To investigate the anti-inflammatory activity of the main active ingredients in the dried stem bark of Daphne giraldii Nitsche.Methods Severialchemical compounds like vladinol D, pinoresinol, daphneticin, daphnoretin, daphnetin, giraloid A and giraldoid B were isolated from the stem barks. The CCK-8 experiemnts were analyzed for the cytotoxicity study. The cells were divided into the control group, the model group and the treatment group according to random number table method. The control group and the model group were added with 50μl culture medium. Moreover, treatment group was added with different concentrations (50.00, 25.00, 12.50, 6.25, 3.12μg/ml) of the solutions of giraloid A, giraldoid B and daphneticin. Then, RAW264.7 cells were treated with 50μl LPS (4μg/ml) for 24 h in the model group and treatment group. Griess reagent was used to determine the amount of NO release, and the secretion of TNF-α was detected by ELISA kit.Results Cytotoxicity test indicated that giraldoid A (50.00μg/ml), giraldoid B (50.00μg/ml) and daphneticin (50.00μg/ml) showed noobvious cytotoxicity. Giraldoid B (12.50, 25.00, 50.00μg/ml) could inhibit the production of NO (271.86% ± 20.92%, 256.48% ± 20.92%, 199.31% ± 15.16%vs.358.62% ± 28.64%) and  TNF-α (647.87% ±115.79%, 618.42% ± 87.52%, 588.33% ± 87.94%vs. 1035.06% ± 58.29%) in RAW264.7 induced by LPS compared with the model group. Giraldoid A (25, 50μg/ml) could inhibit the production of NO (234.99% ± 34.28%, 167.36% ± 25.76% vs.358.62%±28.64%) and TNF-α (691.76% ± 60.37%, 534.01% ± 41.60% vs. 1035.06% ± 58.29%) in RAW264.7 induced by LPS compared with the model group. Daphneticin (12.5, 25, 50μg/ml) could inhibit the production of NO (283.89% ± 36.69%, 243.08% ± 48.19%, 225.92% ± 33.67% vs.358.62% ± 28.64%) and TNF-α (713.77% ± 121.96%, 670.62% ± 18.70% vs. 1035.06% ± 58.29%) in RAW264.7 induced by LPS compared with the model group.Conclusions Giraldoid A, giraldoid B and daphneticin exhi bited anti-inflammatory effect through inhibiting the release of NO and the production of TNF-α in RAW264.7 induced by LPS.

Background One of the features of the pathogenesis of primary angle-closure glaucoma(PACG) is anterior synechia of peripheral iris.Goniosynechialysis and combination of phacoemulsification and goniosynechialysis have been applied for the treatment of the disease recently,but the selection of operative types has great impact on clinical efficacy.Objective This study was to investigate the long-term efficacy of goniosynechialysis and combination of phacoemulsification and goniosynechialysis for the management of chronic PACG.Methods A non-randomized clinical controlled trial was designed.This clinical trial complied with Declaration of Helsinki and was approved by Medical Ethic Committee of Nanjing Medical University.Written informed consent was obtained from each patient.One hundred and ten eyes of 110 patients with chronic PACG were assigned to the goniosynechialysis group and combined operative group from March,2008 to February,2011 in Wuxi People's Hospital.180° goniosynechialysis was performed on 34 patients in the goniosynechialysis group,and phacoemulsifieation +intraocular lens (IOL) implantation + goniosynechialysis were carried out in 78 patients of the combination operative group.All the patients were followed-up for 2 years.Vision acuity,intraocular pressure (IOP),anterior chamber depth(ACD),unltrasound biomicroscopy and perimetry were recorded and compared between before and after operation.Results No significant difference was found in vision acuity between preoperation and postoperative 2 years in the goniosynechialysis group ([0.65 ± 0.15] vs.[0.45 ± 0.15]) (t =1.57,P＞0.05),but in the combination operative group,the vision acuity was significantly different between the before and after operation ([0.25±0.15] vs.[0.85 ±0.05]) (t =9.12,P＜0.001).The lOPs at 2 years after operation were (14.2±4.1) mmHgand(13.7±4.8) mmHg,respectively in the goniosynechialysis group and combination operative group and were significantly lower than(47.2 ±6.3) mmHg and(46.9±7.0) mmHg before operation(t =4.95,P＜0.001 ;t=5.03,P＜0.001).The ACD values in the goniosynechialysis group and combination operative group were(3.38±0.02)mm and (3.54±0.03) mm 2 years after operation,which were significantly increased in comparison with (1.33 ±0.24)mm and (1.56±0.37) mm before operation(t=7.65,P＜0.001;t=6.76,P＜0.001).Conclusions Both combination of phacomulsification with goniosynechialysis or 180° goniosynechialysis are effective for the treatment of PACG.Suitable operation should be alternated depending on the indicators of PACG patients.

Objective To investigate the usefulness of 99Tcm-MDP whole body bone scintigraphy (WBBS) in patients with synovitis,acne,pustulosis,hyperostosis,osteitis (SAPHO) syndrome.Methods 99Tcm- MDP WBBS was performed in 25 patients (6 males,19 females,mean age =(55.1 ±9.8) years)with SAPHO syndrome.Bone lesions were classified into five categories:anterior chest wall,spine,mandible,sacroiliac joint,and limbs.The typical scintigraphic manifestations of SAPHO syndrome were summarized and compared to other radiological imaging data.Results Among 25 patients,32％ of cases (8/25)were associated with skin lesion; 48％ ( 12/25 ) were pathologically diagnosed with chronic nonspecific bone inflammation by bone biopsy.On 99Tcm-MDP WBBS,abnormal metabolic foci at anterior chest wall were found in all cases,most of which located in the sternocostoclavicular region (96％,24/25 ),including sternoclavicular joints (60％,15/25),first costosternal junctions (48％,12/25),and manubriosternal junctions (44％,11/25 ).Only 20％ of the patients (5/25) demonstrated the typical scintigraphic characteristic:“bull's head” sign.The second most frequent part was spine (44％,11/25).Appendicular skeleton was affected in 16％ (4/25) patients.WBBS also demonstrated additional skeletal lesions in 68％ (17/25 ) of the patients,mainly in first costosternal junctions (7 patients),sternoclavicular joints (6 patients),manubriosternal junctions (5 patients) and spine (4 patients).Conclusions Abnormal metabolic foci in sternocostoclavicular region and other imaging manifestations on 99Tcm- MDP WBBS can be used to diagnose,differentiate,and localize the insidious lesion and evaluate the lesion activity in patients with SAPHO syndrome.

BACKGROUND: The maximal problem of patient with serious hepatitis and surgical doctor is whether they can get donator and rational therapy timely. Looking for the suitable preoperative therapy method to enhance the success rate of operation and improve patient's prognosis is the focus of this domain.OBJECTIVE: To investigate the therapeutic effect of artificial liver support system (ALSS) combining with allotransplantation of the liver on patients with serious hepatitis.DESIGN: Retrospective case analysis. SETTING: Organ Transplantation Center, the Third Affiliated Hospital of Anhui Medical University.PARTICIPANTS: Five male patients with serious hepatitis who underwent allograft liver transplantation were selected from Organ Transplantation Center, the Third Affiliated Hospital of Anhui Medical University form June 2004 to May 2005. Their age ranged from 25 to 48 years. Inclusion criteria: The diagnosis was in accordance with phase standard established at the National Infectious Disease and Parasitology Academic Meeting in September 2000; all patients had signs of routine liver transplantation; their patients fiercely requested the operation.METHODS: Plasma exchange (PE) combined with continuous veno-venous hemofiltration (CVVH) technique was used in this study. Donor who supplied lives was from 20-38-year patients. All of them and their family agreed to donate their organ and signed the donate file before operation. All of 5 patients were used classical no-by-pass orthotopic liver transplantation (OLT). MAIN OUTCOME MEASURES: They were follow-up visited for 21-32 months for rechecking liver and kidney function,RESULTS: All of 5 patients' operation was succeeded. One continued coma postoperative and his serum creatinine and urea nitrogen raised up progressively and complicated by pulmonary infection 1 week after operation and died 2 weeks after operation although given medical treatment hemodialysis positively. The rest recovered well. All of them discharged one month after operation smoothly.CONCLUSION: Allotransplantation of the liver is an utilizable method to treat serious hepatitis. ALSS can be used as an effective method of supportive treatment preoperatively.

Objective To observe the effects of low-dose ultra-shortwaves radiationon the expression of apoptosis-related genes Bcl-2 and Bax in lens epithelial cells(LECs) of rats.Methods Thirty-six Wistar rats were divided into a normal group(n=8 eyes),a control group(n=32 eyes) and an experiment group(n=32 eyes) randomly.Both eyes of each rat in the experiment group were exposed to a low-dose ultra-shortwave radiation for 7min,once a day until the end of experiment,while the control groups were not.Rats were executed after 1 w,3w,6w and 9w.Both eyes were resected,and lens were separated under a microscope and sectioned in paraffin.After Streptavidin-Biotin Complex (SABC) staining,Bcl-2 and Bax expression in the LECs were detected using an image analysis technique,and the data were analyzed using the software of SPSS 13.0.Results The average integral optical density (AIOD) of Bcl-2 expression in the experiment group was (0.391 ± 0.014) after 1 week,(0.4470.006) after2,(0.417 ±0.011) after3 and (0.275 ±0.007) after4 weeks.The corresponding AIODs for Bax expression were (0.180 ±0.015),(0.155 ± 0.007),(0.167 ± 0.003) and (0.251 ± 0.016) respectively.After l w of daily radiation,no significant difference was found in the expressions of Bcl-2 and Bax protein between the experimental and the other 2 groups(P ＞ 0.05).Three weeks after the radiation,however,the expression of Bcl-2 protein in the experimental group was significantly higher than the control groups(P＜0.001),with that of Bax being significantly lower(P＜0.001).However,the expressions of Bcl-2 protein was significantly down-regulated and the expression of Bax protein was significantly up-regulated 6w later compared with those after3 w of exposure in the experiment group(P＜0.001) After9w,in the experimental group,the expressions of Bcl-2 protein was obviously down-regulated and significantly lower than the control group.Moreover,the expression of Bax protein increased significantly compared to the control group (P＜0.01).And there was no significant difference between the control and normal group(P＞0.05) in the expression of Bcl-2 and Bax.Conclusions Low doses of ultra-shortwave radiation may protect LECs against apoptosis for a few days,but they may cause damage with repeated exposure.

Objective To observe the curative effect of captopril and metoprolol in the treatment of chronic Keshan disease (CKD). Methods One hundred and ninty-five patients with CKD chosen from Juxian, Wulian, Yishui, Pingyi, Sishui and Zoucheng in Shandong Province were randomly assigned to control group, captopril group and metoprolol group according to NYHA cardiac functional grading. All cases were given diuretics, digitalis and vasodilating agents as routine treatment. On this basis, captopril and metoprolol was administered in captopril group and metoprolol group respectively. After 12 months of follow-up visit, the causes of cardiac death, hospitalization status and the changes of heart size, electrocardiogram, blood pressure and heart rate were all observed. Results It was found that the mortality of captopril group and metoprolo] group was 4.76% (3/63), 5.00% (3/60) respectively, both lower than the control group 10.61%(7/66). But this difference had no statistically significance(P=0.39). Besides, the hospitalization days of each year in captopril group and metoprolol group was respectively (19.12± 20.35) and(18.86±21.52)days, much more reduced than in the control group[(21.45±21.74)days, q=3.17, 3.38, P<0.05]. The detection rate of cardiothoracic ratio decreased in captopril group and metoprolol group [45% (27/60) and 40.4% (23/57)] After treatment showed more pronounced amelioration than the control group [18.6% (11/59), χ2=9.51,6.59, all P<0.0125], still the detection rate of cardiomegaly and invariability had no significant difference among three groups (χ2=2.50,4.75, all P>0.05). The elimination coefficient of ectopic rhythm in metoprolol group [56.5% (13/23)] was pronounced higher than the control group and captopril group [23.8% (5/21), 22.7% (5/22)], but differences had no statistically significance(P=0.0358,0.0331, all P>0.0125). Significant differences were found in systolic blood pressure(SBP), diastolic blood pressure(DBP) and heart rate(HR) in three groups prior and post-treatment(F=47.51,44.23,80.66, all P<0.01). The interaction of therapy and treatment time had influence on SBP and HR (F=3.19,37.44, all P<0.05), but had no influence on DBP(F=2.21, P> 0.05). There was no difference in SBP, DBP or HR among three groups before treatment(F=0.28,0.57,1.80, all P>0.05). After treatment, SBP and DBP in captopril group, metoprolol group and the control group[(109.0±10.9), (112.2±12.8), (114.7±13.2)mm Hg, (69.3±7.2), (72.1±9.5), (73.3±9.3)mm Hg] were all lowered compared with pre-treatment[ (117.1±13.4), (119.0±14.4), (117.6±14.1)mm Hg and (74.2±10.2), (76.3±10.8), (75.4±11.1)mm Hg, t=4.79,4.47,2.08,5.12, 4.32,2.15, all P<0.05]. HR was reduced in metoprolol group, being [(66.2±7.7), (75.9±11.5)times/min] before and after treatment(t=10.81, P<0.01), while it remained unchanged in captopril group and control group[(70.6±8.0), (72.6±10.5) times/min and (71.9±10.4), (73.8± 12.2)times/min, t=1.77,1.74, all P>0.05]. After treatment, both SBP and DBP of captopril group were significantly lower than that in the control group (q=3.52,3.56, all P<0.05); HR was reduced in metoprolol group, lower than that in captopril group and control group(q=5.44,3.73, all P<0.01). Conclusions Having a tendency of depressing mortality, captopril and metoprolol can reverse or delay myocardial remodeling and reduce admission rate in a safe,reliable and economic way, and are worth to be widely used in the treatment of chronic Keshan disease.

Objective:To study the antimalarial mechanism of benflumetol (B). Methods: Flow cytometry (FCM) was used to analyze the effects of B and chloroquine (CQ) on DNA content of Plasmodium berghei and pH value of the lysosome of malarial parasites. Results: DNA content of the plasmodia not treated with any drugs was not changed in 24 hours,while benflumetol could decrease the DNA content: the DNA content began to decrease 2 h after the drug administration and reached the minimum by 16 h, but somewhat increased at 24 h after administration. The pH in the lysosome increased 1 h and restored premedication level 4 h after benflumetol administration. Chloroquine had the same effects on DNA and lysosome pH of malarial parasites.Conclusions: The antimalarial mechanism of benflumetol is directly related to its effect to inhibit the synthesis of DNA.
