The data mining technique is adopted to analyze characteristics and rules of acupoint and meridian selection of acupuncture-moxibustion for treatment of vertigo at different time periods in the ancient. The data is collected from literature regarding acupuncture-moxibustion from the pre-Qin period to the end of Qing Dynasty, so as to establish a clinical literature database of ancient acupuncture-moxibustion for treatment of vertigo. Data mining method is applied to analyze the commonly used meridians, acupoints and special acupoints in different dynasties, also possible rules are explored. Totally 82 pieces of prescription of acupuncture-moxibustion for treatment of vertigo are included. In the history the leading selection of acupoitns are Fengchi (GB 20), Hegu (LI 4), Shangxing (GV 23) and Jiexi (ST 41) while that of meridians are mainly three yang meridians of foot and the Governor Vessel, especially the acupoints on the Bladder Meridian of foot yangming had the highest utilization rate, accounting for 23.04%. The acupoint selection is characterized by special acupoint, accounting for 80.6%, among which the crossing points are the most common choice. Distal-proximal acupoints combination is the most frequent method. The results indicate that the ancient acupuncture-moxibustion for treatment of vertigo focused on acupoints in the yang meridians, and the specific acupoints play an essential role in prescription; also the principle of syndrome differentiation and selecting acupoints along the meridians could be seen.

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 observe the electrocardiogram changes of threatened crowds in Keshan disease (KSD) endemic area in Shandong province. Methods In 2008,inhabitants from 21 villages of Zoucheng,Sishui,Tengzhou, Yishui, Pingyi, Wulian, Juxian and Qingzhou regions were selected as subjects undergoing electrocardiogram. No less than 100 people were chosen from each village and the examination rate was not lower than 85%. Results Among the 3378 inhabitants investigated,460 cases showed abnormal electrocardiogram and the total incidence of abnormal electrocardiogram was 13.62% (460/3378). The relatively high incidence was T-wave changes,QRS low voltage and ST-T changes,the detection rate being respectively 2.69% (91/3378), 1.92% (65/3378) and 1.72% (41/3378). The highest incidence of abnormal electrocardiogram (26.76%,55/213),the intermediate(21.50%,43/200) and the lowest(5.50%,12/218) was respectively found in Pingyi,Qingzhou and Sishui. Conclusions The threatened crowds in KSD endemic area in Shandong province are still in a state of high abnormal electrocardiogram detection,and electrocardiogram is of great value in the evaluation of KSD patients.

Objective To screen the arsenic content situation of drinking water in lower reaches of Yellow River and survey the amount of threatened people drinking high arsenic water and the condition of endemic arsenism.Methods Four counties of Yuncheng,Jiaxiang,Dongchangfu and Boxing were selected to colleft the water samples by CroOSS-sectional survey method.The water arsenic content wag determined by semi-quantitative rapid kit.All water samples having arsenic were re-determined by atomic fluorescence spectrometry.And the nurober of threatened people who drinking high arsenic water were investigated.Results In 4765 water wells screened,303 water samples had contained arsenic,arsenic content of 35 samples Was≥0.030 mg/L,12 samples were exceeding the international standard (arsenic content≥0.050 ms/L),they distributed in 3 counties of Dongchangfu,Yuncheng and Jiaxiang.The residents drinking water wells of arsenic content≥0.030 mg/L were surveyed by epidemiological investigation.And in the 28 villages 13 032 residents and 11 Bu8picious patient8 wlere checked out.Conclusion The wells with excesive water arsenic content are existing in the lower reaches of Yellow River and people suspicious of endemic arsenism need to be further identified.

OBJECTIVETo investigate the expression of androgen receptor (AR) and hepatitis B virus X protein (HBx) in hepatocellular carcinoma (HCC), and analyze the relationship between AR and HBx expressions.

METHODSTumor tissues and peritumoral tissues of 83 HBV-associated HCC cases were investigated in this study. Fourteen cases of HBV-negative HCC and 13 cases of hemangioma peritumoral tissues were considered as control. AR and HBx mRNA levels were determined by quantitative fluorescence real-time RT-PCR and their protein levels were assayed by Western blot. The expression of AR and HBx proteins in tissues were examined with EnVision immunohistochemical staining. The methylation status of AR promoter was determined using methylation-specific PCR (MSP).

RESULTSBoth expression levels of AR mRNA and protein of the peritumoral tissues were significantly higher (0.17) than that of tumor tissues (0.09) in HBV-associated HCC (P < 0.01), but such a difference was not found in HBV-negative HCC (0.06 vs. 0.07, P > 0.05). The level of AR expression in peritumoral tissues was associated with tumor differentiation in HBV-associated HCC. AR mRNA and protein levels of peritumoral tissues in HBV-associated HCC were significantly higher than that in HBV-negative HCC and hemangioma (all P < 0.05). In the tumor tissues, HBV-associated HCC had significantly higher AR expression than HBV-negative HCC at mRNA level (P < 0.05), but not at protein level. Spearman rank correlation analysis showed that the AR mRNA or AR protein levels were positively correlated with HBx in both tumor and peritumoral tissues in HBV-associated HCC, but the expressions of AR and HBx were not associated with AR promoter methylation status. The relative expression levels of AR mRNA and protein in the HBV-associated peritumoral tissues were negatively correlated with tumor differentiation (r = -0.213, P < 0.05; r = -0.313, P < 0.05), the higher the AR expression, the poorer differentiation. But this correlation of AR mRNA and protein was not shown in the hepatocellular carcinoma tissues.

CONCLUSIONSHBx may enhance AR expression in HBV-associated HCC, but AR promoter demethylation maybe not been involved in its main mechanism. An increased AR expression is probably an early event during the development and progression of HBV-associated HCC, and AR expression in the peritumoral tissue is correlated with HBV-associated HCC differentiation. AR may play different roles in HBV-associated HCC and HBV-negative HCC.

OBJECTIVETo compare the differences of the gene expressions in androgen-independent and androgen-dependent prostate cancer (ADPC), gain a deeper insight into the molecular mechanism of androgen-independent prostate cancer (AIPC), and find effective means for its clinical diagnosis and treatment.

METHODSEats of genes highly-associated with prostate cancer were obtained by mining PubMed with the FACTA tool, and the specifically expressed genes in AIPC were analyzed with a set of bioinformatic tools including GATHER, PANTHER, STRING and ToppGene.

RESULTSA total of 128 genes specifically expressed in AIPC were identified, as compared with 23 that were specific to ADPC. Bioinformatic analysis showed the essential roles of AIPC-specific genes in such important biological processes as cell signal transduction, cell adhesion, apoptosis, oncogenesis, cell proliferation and cell differentiation.

CONCLUSIONSuch genes as MMPJ, EGFR, MMP2, ADM, MIF, IGFBP3, 112, MET, BAD, RHOA, SPP1, EP300, SMAD3, RAE1, PTK2, and TGFB2 may play important roles in transforming ADPC into AIPC.

OBJECTIVETo investigate the influence of substance P (SP) on the release of histamine in the human hypertrophic scar tissue, and to explore the prerequisite of their interaction.

METHODSTissue specimens of normal skin and hypertrophic scar from eight hospitalized patients were excised and cut into 0.5 to 1.0 mm3 pieces, and the histamine release by mast cell (MC) under the stimulation of different concentration of SP and calcium, as well as the different affect time of SP, were determined with fluorescence spectrometer. Then the histamine release rate was calculated.

RESULTSThere was obvious release of histamine when SP concentration was 1 x 10(-6) mol/L , and the release rate was (50.0 +/- 3.6) %, which was significantly higher than that by SP in the concentration of 0 mol/L [(44.0 +/- 3.2) %, P < 0.01]. Therefore it seemed to be dose-dependent. About 90% of histamine was released within 15 minutes of 5 x 10(-1) mol/L Substance P stimulation, and it was also time-dependent. The histamine release reached the peak when calcium concentration was 5 x 10(-3) mol/L, which seemed to be dose-dependent, but it decreased transiently when calcium concentration was 1 x 10(-3) mol/L. In all occasions, the influence of SP on the histamine release by MC in hypertrophic scar (HS) was markedly higher than that in normal skin (NS) (P < 0.01). Conclusion The influence of SP on the histamine release by MC in HS was markedly higher than that in NS, and it might be closely related to itching sensation and the formation of hypertrophic scar.
