OBJECTIVETo compare the differences of therapeutic effect of chronic fatigue syndrome treated with the combined therapy of coiling dragon needling and cupping on back and the western medicine therapy with Prednisone.

METHODSSeventy-two cases were randomly divided into an acupuncture and cupping group (37 cases) and a Prednisone group (35 cases). In acupuncture and cupping group, Jiaji (EX-B 2) points of T1--L5 were applied with coiling dragon needling (once a day), combined with moving cupping on back (once every two days); in Prednisone group, Prednisone tablets were orally taken for 10 mg at 8:00 am. Seven days made one course, and 2 courses were carried on totally. FS-14 scale and BELL's chronic fatigue syndrome integral table were applied to evaluate the fatigue degree of patients before and after treatment, and the therapeutic effects of both groups were compared.

RESULTSAfter one course of treatment, the BELL's scores of both groups were obviously improved (both P < 0.01), but there was no significant difference between groups (P > 0.05); after two courses of treatment, the BELL's score in acupuncture and cupping group improved more obviously than that in Prednisone group, and the total effective rate of 91.9% (34/37) in acupuncture and cupping group was superior to that of 71.4% (25/35) in Prednisone group (P < 0.05).

CONCLUSIONThe therapeutic effect of chronic fatigue syndrome treated with coiling dragon needling and moving cupping on back is positive, superior to that of Prednisone with oral administration.

OBJECTIVETo observe the clinical therapeutic effect of moxibustion on heat-sensitive acupoints on myofascial pain syndrome (MPS).

METHODSThree-centre, single blind, randomized controlled trial method was adopted. One hundred and seven cases were randomly divided into an observation group (n = 57), and a control group (n = 50). The observation group were treated by moxibustion on the heat-sensitive acupoints and the control group by acupuncture, cupping and TDP. The therapeutic effects were assessed according to changes of the score of the short-form of McGill pain questionnaire composing of pain rating index (PRI), visual analogue scale (VAS) and present pain intensity (PPI) before and after treatment.

RESULTSThe cured rate of 86.0% in the observation group was better than 24.0% in the control group. After treatment, the score of PRI, VAS, PPI indexes significantly improved in the observation group (P < 0.001), and were significantly better than those in the control group (P < 0.001).

CONCLUSIONMoxibustion on the heat-sensitive acupoints has a high therapeutic effect on MPS.

OBJECTIVETo describe the characteristics of magnetic resonance (MR) signals generated by lipiodol and to assess the influence on MR imaging of hepatoma nodule.

METHODSPure lipiodol and lipiodol emulsions mixed with 76% urografin in different ratio were imaged by both CT and MR; quantitative T(1) and T(2) measurements of lipiodol were performed. Fourty-one SD rats with transplanted walker-256 sarcoma in liver were randomly divided into six groups: 0.4-0.6 ml lipiodol emulsion was infused via hepatic artery in experimental groups by means of laparotomy under celiac anesthesia. The changes in MRI signal of hepatoma nodule were observed.

RESULTIn vitro, iodized oil demonstrated high signal on T(1)-weighted images when performed at 37 degree, but all could be suppressed by the fat saturation sequence, and showed very low signal on T(2)-weighted images. The characteristic of MR signal with ultra fluid lipiodol was different from that of iodized oil (P<0.01), showing short T(1) and long T(2) signal; the high signal on T(1)-weighted images was only partially suppressed by the fat saturation sequence. With descending ratio of lipiodol in emulsion, the signal behavior was gradually similar to urografin (r -0.958, P<0.01). When rats were transarterially infused with emulsion, the intensity of the signal on MRI was nearly the same as that in the control rats, but when lipiodol was injected out of the hepatic artery and accumulated in lymphadenopathy, it demonstrated a signal similar to fat; the high intensity signal was maintained on T(1)-weighted images and T(2)-weighted images.

CONCLUSIONThere are little changes in MR signal intensity when the lipiodol is accumulated in the tumor nodules. MR behavior of lipiodol is determined by its deposit area.

OBJECTIVEIn order to find out the factors related to hemorrhagic fever with renal syndrome (HFRS) infection, and to evaluate the probability of ecdemic hantaviruses (HV) infection in rodents in Beijing areas.

METHODSRodents were collected in a large-scale railway station and a produce market with 'trap nights' method from April to May, 2004. The IgG reacting sera to HV antigen were detected using ELISA. The partial M and S segment of HV from captured rodent lung samples were amplified with RT-PCR. The PCR products were purified and sequenced. BLAST program was then used to perform on nucleotide pairwise alignment with all available sequence in GenBank. The alignment of the multiply nucleotide and the deduced amino acid sequences, together with phylogenetic analysis were completed with DNASTAR software.

RESULTSThe average population density was 3.49% (24/690). The overall seroprevalence of HV infection was 8.3% (2/24). RT-PCR positive rates were 8.3% (2/24). The nucleotide sequences of 356 bp region (1958 - 2313) of M segment obtained from 2 samples were all identified to Seoul virus (SEOV), with 7.6% heterogeneity. The dc501 strain from railway station was closely related to SD227 and Hebei4 from Shandong and Hebei provinces respectively. BjFT01 strain from the farm product market had more special nucleotide transitional mutations than other known SEOV from Beijing in GenBank. This strain, together with known HN71 from Hainan province, K24-E7 from Zhejiang province, L99 from Jiangxi province and R22 from Henan province, represented a monophylogentic linkage.

CONCLUSIONThe higher HV prevalence of rodents in transportation center was the potential and important risk for HFRS epidemic in Beijing. The increasing prevalence of M. musculus should call for attention. It was possible that SEOV in Beijing was imported by infected rodents through vehicles from other provinces.

The current study aims to investigate the pharmacokinetic properties of Huangqin Tang on different oral doses. An LC-MS method for simultaneous determination of flavonoids and terpenoids in rat plasma was developed and validated. Plasma samples were treated with hydrochloric acid (containing 1% ascorbic acid), precipitated with acetonitrile, separated on a Zorbax SB-C18 column, detected by single quadruple mass spectrometry with an electrospray ionization interface, and quantified using selected ion monitoring mode. All pharmacokinetic parameters were processed by non-compartmental analysis using WinNonlin software. The results of specificity, linearity, intra-day and inter-day precisions, accuracy, and stability for LC-MS assay were suitable for the quantification of paeoniflorin, baicalin, wogonoside, baicalein, wogonin, oroxylin A, glycyrrhizic acid and glycyrrhetinic acid in rat plasma. The concentration-time profiles of baicalin, wogonoside, baicalein, wogonin, oroxylin A and glycyrrhizic acid showed double-peak phenomenon after Huangqin Tang was orally administered at 40 g x kg(-1) dose; all eight constituents in rat plasma showed good dose-exposure relationship within the dosage of 10-40 g x kg(-1); although plasma concentrations were different, the flavonoids with the same backbone showed the similar fate in the body with the corresponding dosage. In conclusion, the LC-MS assay was successfully applied for the pharmacokinetic study of multi-constituents of Huangqin Tang with different doses. Additionally, these constituents demonstrated good pharmacokinetic properties in the body.

OBJECTIVETo investigate the change of early serum TNF-alpha and IL-6 levels in acute cerebral infarction and its significances.

METHODSSerum TNF-alpha and IL-6 levels in 30 health subjects and 35 patients with acute cerebral infarction (ACI) within 6 hours of onset were measured by enzyme linked immunosorbent assay (ELISA); neurological deficits scores (NDS) in all cases were determined, and Spearman test was used for correlation.

RESULTSThe serum levels of TNF-alpha and IL-6 in ACI group were markedly higher than those in health subjects and there was a positive correlation of TNF-alpha and IL-6 levels with 6 h NDS (rs=0.89 and 0.93, P<0.001) and with NDS progression (rs=0.90 and 0.91, P<0.001). Early serum TNF-alpha and IL-6 levels in progressive cerebral infarction (PCI) group were evidently higher than those in stable cerebral infarction (SCI)[(49.56+/-12.12) pg/L compared with (24.30+/-7.4) ng/L and (39.76+/-7.88) ng/L compared with (20.78+/-6.28) ng/L, respectively, P<0.01)].

CONCLUSIONThe early serum levels of TNF-alpha and IL-6 in ACI markedly increase and are closely correlated with disease severity; which may be of value in PCI risk evaluation.

BACKGROUND: Atorvastatin has a cardiovascular protective effect that significantly improves endothelial function and promotes the mobilization,migration,and differentiation of endothelial progenitor cells.However,the screening of atorvastatin concentration for in vitro cell culture is not well documented. OBJECTIVE: To investigate the effects of different concentrations of atorvastatin on rat bone marrow-derived EPCs growth characteristics. METHODS: Bone marrow mononuclear cells from Sprague-Dawley rats were induced in selective culture fluid to culture EPCs. Immunofluorescence staining was used to identify cell surface markers. Harvested EPCs were divided into control group and atorvastatin groups with four different concentrations (0.01, 0.1, 1, and 10 μmol/L) for culture. The growth and proliferation of EPCs were observed under light microscope and MTT assay. Flow cytometry was used to detect apoptosis in EPCs. Nitric oxide and endothelial nitric oxide synthase levels in the culture fluid were measured by nitrate reductase method. RESULTS AND CONCLUSION: The number of cells tended to increase in the control and atorvastatin groups, and it was highest in the 1 μmol/L atorvastatin group. The cell number in the 10 μmol/L atorvastatin group began to decrease at 7 days of culture. Among the five groups, the apoptotic rate of cells was lowest in the 1 μmol/L atorvastatin group and highest in the 10 μmol/L atorvastatin group. The levels of nitric oxide and endothelial nitric oxide synthase were significantly higher in the 0.01, 0.1 and 1.0 μmol/L atorvastatin groups compared with the control group (P < 0.01), but lower in the 10 μmol/L atorvastatin group compare with the other groups (P < 0.01). Overall, atorvastatin can promote the proliferation of endothelial progenitor cells and reduce apoptosis by increasing the production of endothelial nitric oxide synthase and nitric oxide, and 1 μmol/L atorvastatin is most suitable for the EPCs culture.

OBJECTIVETo study the related factors of central lymph node (CLN) metastasis in papillary thyroid carcinoma (PTC),the indications and the extent of central neck dissection (CND).

METHODSA total of 153 cases treated between Jan. 2009 and Dec. 2010 was analysed retrospectively. Of the cases 28 males and 125 cases females, with a mean age of (44 ± 14) years. T1, T2, and T3 diseases accounted for 51, 10 and 81 cases, respectively; I, II, III and IV diseases for 88, 3, 26 and 36 cases, respectively. Multifocal tumors were found in 63 cases. The related clinicopathologic factors were analyzed, including sex, age, tumor size, extrathyroidal extension, and multifocal tumor.

RESULTSAll the cases had total/near total thyroidectomy and CND, of them 64 cases had unilateral neck dissection and 18 cases had bilateral neck dissection. CLN metastases existed in 68.6% (105/153) cases, 37.2% (57/153) for unilateral and 31.4% (48/153) for bilateral respectively. The rates of CLN metastasis were 86.6% (71/82) in cN1 cases and 47.9% (34/71) cN0 cases, respectively,and the rates of bilateral CLN metastases were 45.1% (37/82) in cN1 cases and 15.5% (11/71) in cN0 cases. Multivariate analysis showed that extrathyroidal extension (P = 0.002, OR = 3.502) was an independent risk factor for CLN metastasis and that lateral neck lymph node metastasis (P = 0.028, OR = 3.080), surrounding tissue invasion (P = 0.014, OR = 3.113), and maximum tumor diameter greater than 1 cm (P = 0.012, OR = 3.732) were independent risk factors for bilateral CLN metastases.

CONCLUSIONSIt is indicated that ipsilateral CND should be obligatory for PTC. Intraoperative frozen section examination should be routine. Bilateral CND should be conducted when ipsilateral CLN metastases accompanied by one of following issues such as more invasive tumor (surrounding tissue invasion, T3 or T4 disease), maximum tumor diameter greater than 1 cm, and lateral neck lymph node metastasis.

BACKGROUNDIt has been suggested that glycated hemoglobin (HbA1c) underestimate the actual glycemic control levels in maintenance hemodialysis (MHD) patients, because of anemia and the using of erythropoietin (EPO); it was recommended that glycated albumin (GA) should be an alternative marker. Therefore, the assessment performances of glycemic control were compared between GA and HbA1c in this research by referring to mean plasma glucose (MPG) in diabetes mellitus (DM) patients undergoing MHD or not.

METHODSMPG was calculated according to the data registered at enrollment and follow-up 2 months later and corresponding HbA1c, albumin (ALB), GA, etc. were measured in 280 cases. A case-control study for comparing GA and HbA1c was done among the groups of MHD patients with DM (n=88) and without DM (NDM; n=90), and non-MHD ones with DM (n=102) using MPG for an actual glycemic control standard.

RESULTSIn these 3 groups, only for DM patients' (whether undergoing MHD or not), GA and HbA1c correlated with MPG significantly (P < 0.01). Through linear regression analysis, it could be found that the regression curves of GA almost coincided in MHD and non-MHD patients with DM, because the intercepts (2.418 vs. 2.329) and slopes (0.053 vs. 0.057) were very close to each other. On the contrary, regression curves of HbA1c did not coincide in the two groups, because variance of the slopes (0.036 vs. 0.052) were relatively large. Through comparing receiver operating characteristic (ROC) areas under the curve (AUC), it could be understood that the assessment performances of GA and HbA1c in MHD patients were lower than those in non-MHD ones, and assessment performance of HbA1c in MHD patients was better than GA (P < 0.05). In addition, the effects of Hb and EPO dose on HbA1c, or that of ALB on GA were unobvious in our study.

CONCLUSIONSActual glycemic control level in MHD patients with DM may be underestimated by HbA1c, and it could be avoided by GA; however, glycemic evaluating performance of HbA1c may be still better than that of GA. Therefore, HbA1c should not be replaced completely although GA can be used as a choice to monitor glycemic level.

Objective: To explore the protective effect of formula of Gougancai decoction (FGD) on acute liver injury induced by carbon tetrachloride (CCl₄) in rats, in order to provide basis for the development of pharmaceutical preparations or healthcare products. Method: Sixty rats were randomly divided into normal group, Silymarin group (120 mg·kg^-1) and FGD groups (475, 950, 1 900 mg·kg^-1). The normal group and the model group were given equal volume of saline by gavage, while the other groups were administered with the corresponding dose of drugs according to the body weight. After 10 days, the acute liver injury model was established with 12% carbon tetrachloride peanut oil solution (5 mL·kg^-1), except the normal group. All of the rats were put to death to collect serum and liver tissues. The contents of aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), total bilirubin (TBIL), malondialdehyde (MDA), superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) were detected by biochemical methods, the levels of tumor necrosis factor-alpha (TNF-α), interleukin-1β (IL-1β) and interleukin-6 (IL-6) in liver tissues were determined by enzyme-linked immunosorbnent assay(ELISA). Nuclear factor-κB (NF-κB) and peroxisome proliferator-activated receptor-γ (PPAR-γ) protein expression in liver tissues were detected by Western blot, and htoxylin eosin (HE) staining was used to observe the variation of liver histopathological. Result: Compared with the normal group, the serum activities of AST, ALT, ALP and the content of TBIL, MDA in the model group were significantly increased (P<0.01), the levels of TNF-α, IL-1β, IL-6 in liver tissue were remarkably increased (P<0.01), but the serum activities of SOD, GSH-Px were significantly decreased (P<0.01), the expression of NF-κB was enhanced in liver tissue (P<0.01), and PPAR-γ was down-regulated (P<0.01), indicating the successful modeling of acute liver injury. Compared with the model group, FGD could reduce the activities of AST, ALT, ALP and the contents of TBIL, MDA (P<0.05, P<0.01), decease the level of TNF-α, IL-1β, IL-6 (P<0.05, P<0.01), and down-regulate the expression of NF-κB (P<0.05, P<0.01), but up-regulate the activities of SOD, GSH-Px and the expression of PPAR-γ (P<0.05, P<0.01). The liver tissue lesions were alleviated to varying degrees. Conclusion: FGD has a protective effect on CCl₄-induced acute liver injury in rats, and its mechanism may be related to the activation of PPAR-γ and the inhibition of NF-κB signaling pathway, with anti-inflammatory and anti-oxidative effects.
