Objective: To observe the clinical efficacy of electroacupuncture (EA) plus long-snake moxibustion for rheumatoid arthritis (RA) due to kidney deficiency and cold coagulation. Methods: A total of 60 patients in active stage of RA were randomly divided into an observation group and a control group, with 30 cases in each group. Patients in the control group took methotrexate tablets and nimesulide dispersible tablets orally for treatment, while those in the observation group received additional treatment of EA plus long-snake moxibustion. Both groups were treated for 12 weeks. The post-treatment changes in symptomatic grading and quantifying score, disease activity score with 28 joint counts (DAS28), and inflammatory indicators erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) were observed, and the efficacy was evaluated. Results: The total effective rate in the observation group was 89.9％, versus 76.6％ in the control group, and there was a significant difference in the total effective rate between the two groups (P<0.05). After treatment, the symptomatic grading and quantifying score and DAS28 in both groups were significantly improved (all P<0.05), and the improvements in the observation group were more significant than those in the control group (both P<0.05). Besides, there were 11 cases with low disease activity index (DAI) and in remission in the observation group versus 5 cases in the control group, showing a statistically significant between-group difference (P<0.05). The ESR and CRP scores in both groups were significantly reduced after treatment (all P<0.05), also showing statistically significant between-group differences (both P<0.05). Conclusion: The efficacy of additional EA plus long-snake moxibustion based on oral medications for RA due to kidney deficiency and cold coagulation is better than that of the oral medications alone.

Objective:Studies on the immune-enhancing activity of Polysaccharides from the fruits of Borojoa sorbilis cuter ( polysaccharides BSCP) in vivo.Methods:54 male BALB/c mice were randomly divided into six groups.The immune suppression mice in the three experimental groups,which were induced by cyclophosphamide ( CY) at 80 mg/kg/d via intraperitoneal injection, were perfused with 100,200,400 mg/kg/d BSCP for 30 d.The effect of BSCP on cellular immune function,humoral immune function and mononuclear macrophage function were measured.Results:CY-treated mice showed a significant decrease in immune function( P<0.05),humoral immune function(P<0.01) and mononuclear macrophage function(P<0.01).The administration of BSCP was able to overcome the CY-induced immunosuppression,treatment with BSCP-L,BSCP-M and BSCP-H groups significantly enhanced the cellular immune function( each was P<0.05 ) and mononuclear macrophage function ( each was P<0.05 ) , and treatment with BSCP-M and BSCP-H significantly enhanced humoral immune function(each was P<0.01).Conclusion:BSCP could significantly increase immune responses and reduce the side effects of CY in immune system.Therefore,the BSCP could be an immunomodulatory agent.

The continuous cultivation of Rehmannia glutinosa causes the accumulation of phenolic acids in soil. It is supposed to be the reason of the so called "continuously cropping obstacle". In this study, phenolic acids (hydroxybenzoic acid, vanillic acid, eugenol, vanillin and ferulic acid) were degraded by the extracta of all the tested spent mushroom substrate (SMS) and the maximal degradation rate was 75.3%, contributed by extraction of SMS of Pleurotus eryngii. Pot experiment indicated that hydroxybenzoic acid and vanillin in soil were also degraded effectively by SMS of P. eryngii. The employment of SMS enhanced ecophysiology index to near the normal levels, such as crown width, leaves number, leaf length, leaf width and height. At the same time, the fresh and dry weight and total catalpol concentration of tuberous root weight of R. glutinosa was increased to 2.70, 3.66, 2.25 times by employment of SMS, respectively. The increase of bacteria, fungi and actinomycetes numbers in rhizosphere soil were observed after the employment of SMS by microbial counts. The employment of SMS also enhanced the enzyme activity in soils, such as sucrase, cellulase, phosphalase, urease and catelase. These results indicated that the employment of SMS alleviated the continuously cropping obstacle of R. glutinosa in some extent.

OBJECTIVESTo investigate whether antisense human telomerase reverse transcriptase (hTERT) could inhibit the activity of telomerase and the proliferation of K562 cells.

METHODSThe antisense plasmid was constructed by reverse insertion of hTERT PCR product into plasmid pLNCX-neo. Then the constructed plasmid was introduced into K562 cells by liposomes-mediated DNA transfection. The inhibition effects of telomerase on the proliferation of K562 cells were analyzed by MTT and colony formation assay, the telomerase activity of K562 cells by TRAP-PCR ELISA methods.

RESULTSThe growth rate of antisense hTERT transfected K562 cells was significantly lower than those of the controls, and the colony formation capacity of the transfected cells decreased significantly (P < 0.01), the colony number is (100.33 +/- 7.57)/10(3) cells, (92.67 +/- 5.86)/10(3) cells and (50.33 +/- 6.11)/10(3) cells for control K562 cells, K562 neo cells and antisense hTERT transfected HL60 cells, respectively. The telomerase activity of antisense hTERT transfected K562 cells was significantly inhibited.

CONCLUSIONThe expression of an antisense sequence to the mRNA sequence of telomerase protein subunit can inhibit the activity of telomerase, slow the cell growth and inhibit the capacity of colony formation of K562 cells.

Objective To discuss the combined value of gray-scale ultrasound ( GSUS) and contrast-enhanced ultrasound (CEUS) in the diagnosis of benign and malignant thyroid lesions and to explore the optimal diagnostic point of scoring method .Methods Ultrasound images of 178 thyroid lesions confirmed by pathology were synthetically reviewed by scoring 5 GSUS indicators including shape , orientation, interior echogenicity, halo sign, microcalcification and 6 CEUS indicators including relative arrival time of microbubbles in the periphery and interior, peak periphery and interior echogenicity, peripheral ring-enhancement, and homogeneity of enhancement .One positive indicator scored one point .The optimal diagnostic points and their clinical value were explored according to ROC curves .Results Scores of GSUS, CEUS and the combination of GSUS and CEUS were significantly different (Z =10.188,9.843,10.705,all P <0.001). Areas under ROC curves of GSUS, CEUS and the combination of GSUS and CEUS were 0.936, 0.919 and 0.964, respectively.Three or more positive GSUS indicators of five in a thyroid lesion predicted that the thyroid lesion was malignant , with the sensitivity of 79.6% and the specificity of 91.2%.Two or more positive CEUS indicators of six in a thyroid lesion predicted that the thyroid lesion was malignant , with the sensitivity of 91.8% and the specificity of 81.2%.Five or more positive GSUS and CEUS indicators of eleven in a thyroid lesion predicted that the thyroid lesion was malignant , with the sensitivity of 93.6%and the specificity of 92.3%.The areas under the ROC curve of GSUS and CEUS were 0.936 and 0.919.The area under the ROC curve of the combination of GSUS and CEUS was 0.964, larger than the areas under the GSUS ROC curve and the CEUS ROC curve.Conclusion Ultrasound is valuable in the differential diagnosis of benign and malignant thyroid lesions , and the combination of GSUS and CEUS is the most valuable with 5 points as the optimal diagnostic scoring method .

OBJECTIVETo discuss the reverse effect of Yinchenhao decoction(YCHD) in dimethyl nitrosamine (DMN)-induced hepatic fibrosis in rats.

METHODThe rat hepatic fibrosis model was established through the intraperitoneal injection with 1% dimethyl nitrosamine (DMN) with a dose of 1.0 mL x kg(-1) x d(-1) for consecutively three weeks, once for the first three days of each. The rats were randomly divided into six groups: the silymarin positive control group (50.0 mg x kg(-1) x d(-1), YCHD high (20.0 g x kg(-1) d(-1)), middle (8.0 g x kg(-1) x d(-1)) and low (3.2 g x kg(-1) x d(-1)) dose groups, the model group and the normal control group. The model group and the normal control group were orally administered with normal saline for consecutively five weeks. The pathologic changes in liver tissues were observed by HE staining. The levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), g-glutamyltransferase (g-GGT), hyaluronic acid (HA), laminin (LN), collagen type IV (CIV) and type III procollagen amino terminal peptide (PIIINP) in serum were determined. The metabolite profiling of amino acid and the content of hydroxyproline in liver tissues were also measured.

RESULTCompared with the model group, YCHD high and middle dose groups could significantly reverse the pathologic changes in liver tissues of rats. YCHD could reduce the levels of ALT, AST, gamma-GGT, HA, LN, CIV, PIIINP in serum and the content of hydroxyproline in liver tissues in a dose-dependent manner, and altered the metabolite profiling of amino acid in rat liver tissues.

CONCLUSIONYCHD has the effect in reversing dimethyl nitrosamine induced hepatic fibrosis in rats.

OBJECTIVETo explore the effect of different nutrition therapies on abnormal glucose metabolism during pregnancy and pregnancy outcomes.

METHODSThe 83 cases of pregnant women with abnormal glucose metabolism who came to nutrition clinic were randomly divided into two groups before 30 weeks pregnancy: 42 cases in traditional food exchange serving group (FES) and 41 cases in food exchange serving based on glycemic load group (FES + GL). Traditional food exchange serving and food exchange serving based on glycemic load were used as the different nutrition therapies for two groups respectively until the time of delivery. The influence of two nutrition therapies on the blood glucose and pregnancy outcomes were observed.

RESULTSThe daily food glucose load (GL) after nutrition therapy in the FES + GL group (145.9 ± 26.3) were significantly decreased than that of the FES group (179.9 ± 28.9, t = 5.602, P < 0.01). Fasting plasma glucose (FPG) and 2 h postprandial glucose (2 h PG) ((4.63 ± 0.97) and (6.15 ± 1.07) mmol/L, respectively) after nutrition therapy in the FES + GL group were significantly lower than that in pre-nutrition therapy ((4.96 ± 0.81) and (9.13 ± 1.61) mmol/L, t = 2.237, 11.202, respectively, all P values < 0.05). The 2 h PG in the FES + GL group ((6.15 ± 1.07) mmol/L) after nutrition therapy was significantly lower than that of the FES group ((6.86 ± 1.26) mmol/L, t = 2.760, P < 0.05). 19.51% (8/41) of the total incidence of complications in the FES + GL group was lower than that (11/42, 26.19%) in the FES group, but the difference was not significant (χ² = 0.524, P > 0.05).

CONCLUSIONFES based on GL was much easier to reduce blood glucose compared with FES. Two nutrition therapies can improve maternal and neonatal outcomes in pregnant women with abnormal glucose metabolism.

OBJECTIVETo explore safe, effective, simple and easy non-drug treatments for grade 1 essential hypertension.

METHODSAccording to TCM syndrome differentiation, 126 cases of grade 1 essential hypertension were classified into 4 types: liver-fire hyperactivity syndrome, yin-deficiency and yang-hyperactivity syndrome, excessive phlegm-dampness syndrome, yin-yang deficiency syndrome, and then the patients were randomly divided into a photoelectric combined with musical treatment group (group A), an acupuncture group(group B) and a placebo group (group C). The acupoints were selected according to TCM syndrome differentiation in group A and group B, and multi-mode audio frequency pulse photoelectric therapeutic apparatus and acupuncture were used in the two groups respectively, once daily. Taichong (LR 3) and Quchi (LI 11) were selected in liver-fire hyperactivity syndrome, Taixi (KI 3) and Sanyinjiao (SP 6) were selected yi yin-deficiency and yang-hyperactivity syndrome, Zusanli (ST 36) and Fenglong (ST 40) were selected in excessive phlegm-dampness syndrome, while Taixi (KI 3) and Guanyuan (CV 4) were selected yi yirryang deficiency syndrome. The group C was treated with oral administration of starch tablet (25 mg), one tablet each time,three times everyday. Ten days were considered as one course, totally three courses were required in the three groups. The blood pressure and scores of TCM syndromes before and after treatment were compared among the three groups.

RESULTSThe blood pressure decreased significantly after treatment in group A and group B (all P<0.01), and the decrease in systolic blood pressure was more significant in group A (P < 0.05). The total effective rate was 90.5 / (38/42) in group A, which was superior to 71. 4 (30/42, P < 0.05) in group B and 19.1% (18/34, P<0. 01) in group C. The scores of TCM syndromes were both improved in group A and group B, but without significant difference between the two groups (P > 0.05).

CONCLUSIONThe clinical effect of multi-mode audio frequency pulse photoelectric therapeutic apparatus for treatment of grade 1 essential hypertension is reliable. Meanwhile, it has the advantages of a non-invasive and simple operation.
