Objective To compare the effects of every-other-day dose simvastatin administration with that of daily therapy of same dose.Methods This was a randomized,prospective,nonblinded clinical trial.The 186 patients with high low-density lipoproteim cholesterol(LDL-C) and/or high total cholesterol (TC),triglycerides (TG),low high-density lipoprotein cholesterol(HDL-C)was studied.All patients were randomized into two groups.The every-other-day do- sing group recerived 20mg of simvastatin in alternate-day and daily dosing group received 20mg of simvastatin every day.Before and after 6 weeks,12 weeks of treatment,serum lipoprotein,Live function tests and ereatine kinase con centra- tion and so on were drawn and bad-side effect were studies.Results The two groups significantly reduce LDL-C,TC, TG and a little increased HDL-C compared with baseline.No stalistically significant differences existed between the two groups in percentage in decrease in lipoprotain at 6 weeks,12 weeks compared with baseline.The bad-side effect in the two groups also had not a singnificant different.Conclusion The every-other-day dose of simvastatin have similar effi- cacious and safe to daily dosing in patients with hyperlipidemia and some cost savings.It can take a primary prevention to coronary heart disease in patients with relatively low-risk hyperlipidemia.

Activation of microglia plays a vital role in the initiation and maintenance of specific neuropathic pain states. By activating microglia in central nervous system, Toll-like receptor 4 (TLR4) can promote the release of proinflammatory cytokines and neuroactive compounds, participate in the initiation and maintenance of neuropathic pain, and trigger the opiate side effects. Therefore, TLR4 may be a potential therapeutic target for neuropathic pain. Inhibition of TLR4 has shown some biological effects in neuropathic pain models and ibudilast (the TLR4 pathway-inhibiting agent) has been approved for for phase 2 clinical trials. This article briefly reviews the structure, function, and mechanism of TLR4 as well as the development of TLR4-targeted drugs.

Objective: To analyze the features and patterns of acupoint selection in acupuncture-moxibustion treatment of chronic atrophic gastritis (CAG) by data mining technique. Methods:Relevant clinical studies published before 25 June, 2017 were searched in databases including PubMed, EMBASE, Cochrane library, Chinese Biomedical Literature Database (CBM), China National Knowledge infrastructure (CNKI), and Wanfang Academic Journal Full-text Database (Wanfang). Results:A total of 122 papers were included, involving 69 points. It was found that the top three points on the frequency list were Zusanli (ST 36), Zhongwan (CV 12) and Weishu (BL 21). The points selected were distributed in 11 meridians, in which the Stomach Meridian of Foot Yangming, Conception Vessel, and Bladder Meridian of Foot Taiyang ranked the top and accounted for 74.0％ of the total frequency. Of the involved specific points, Five Shu-Transmitting points, crossing points and Back-Shu points ranked the top, accounting for 47.1％. The analysis of association pattern has shown that Zusanli (ST 36) and Zhongwan (CV 12) won the highest support rate in the paired groups; Zusanli (ST 36), Weishu (BL 21) and Zhongwan (CV 12) had the highest support rate among the point groups. The Five Shu-Transmitting points and the Lower He-Sea points had the highest support rate among the specific point groups. Conclusion: The data mining results of the studies on acupuncture-moxibustion for CAG are substantially in line with the acupuncture-moxibustion treatment theories in traditional Chinese medicine. The results can reflect the acupoint selection patterns in treatment of CAG and provide reference for acupuncture-moxibustion treatment of CAG in clinic.

Based on the deletion information of high virulent PRRSV genome, 3 oligonucleotide primer were designed and synthesized. Specific and sensitive reverse transcription-PCR (RT-PCR) assays were de-veloped for the detection of high virulent PRRSV. The sensitivity and specificity of RT-PCR assays were evaluated, the results showing that the detection limit of the assay was found to be 0.265 pg of tissue total RNA, and the protocol have no cross-reaction with classical swine fever virus, porcine circovirus type 2,pseudorabies virus, streptococcus, haemophilus parasuis and Escherichia coli. Then 36 cell cultures, two PRRSV live vaccine strains and 184 clinical specimens from 52 farms were tested. Five PRRSV field iso-lates were the high virulent PRRSV; two PRRSV live vaccine strains from normal PRRSV, and 123 speci-mens from 42 farmer were positive (only 1 specimen was normal PRRSV). This RT-PCR method proved to be accurate differential diagnosis of the high virulent PRRSV and normal PRRSV with the characteristics of rapidity, sensitivity and specificity, and has a strong clinical relevance.

Heat shock protein 90 (HSP90) is a member of genetically conserved heat shock protein family. As an important molecular chaperone in eukaryotic cells, HSP90 plays a key regulatory role in maintaining cellular protein homeostasis. HSP90 clients encompass a wide range of proteins, thus HSP90 is involved in diverse biological process. With the deeper study, it is found that HSP90 takes an important part in the development and metastasis of cancer,and has become a promising target for the study of anticancer biology. We review the progress of HSP90 as molecular chaperone and its relationship with cancer.

BACKGROUND: Proximal femoral nail anti-rotation is widely used to treat various intertrochanteric fractures. Although its operation trauma is small, and the blood loss of perioperative period is still large. Tranexamic acid has been gradually used to reduce the bleeding of intertrochanteric fracture. The effectiveness and safety of reducing blood loss during perioperative period were not reported. OBJECTIVE: To explore the safety and efficacy of tranexamic acid on perioperative blood loss in patients with intertrochanteric fracture undergoing proximal femoral nail anti-rotation. METHODS: One hundred and eight patients with intertrochanteric fracture undergoing proximal femoral nail anti-rotation were selected from First Affiliated Hospital, Guangzhou University of Chinese Medicine between January 2015 and January 2017. Among all the subjects, 52 patients who received the operation before January 2016 served as the control group and 56 patients who received the operation after January 2016 were selected as the treatment group. Half an hour before operation, patients in the treatment group received 1 g tranexamic acid dissolved in 250 mL normal saline by intravenous dropping; patients in the control group just received 250 mL normal saline by intravenous dropping. The bleeding volume, blood transfusion volume, hemoglobin, hematocrit, coagulation index, D-dimer levels and complications were compared between the two groups. RESULTS AND CONCLUSION: (1) During perioperative period, actual blood loss, intraoperative blood loss, dominant blood loss, recessive blood loss, volume of drainage, blood transfusion volume and blood transfusion rate were lower in the treatment group than in the control group (P < 0.05). (2) There was no statistically significant difference in the hemoglobin and hematocrit between the two groups before operation (P > 0.05). The hemoglobin and hematocrit of the two groups gradually decreased after the operation, and there was a slight improvement in the fifth day after surgery. At postoperative 2 hours, 1, 3 and 5 days, the hemoglobin and hematocrit of the treatment group were higher than in the control group (P < 0.05). At preoperation and each time point postoperation, prothrombin time, activated partial thromboplastin time, and fibrinogen levels were not statistically significant between the two groups (P > 0.05). Postoperative D-dimer levels in the two groups were significantly higher than preoperation, and there was a return on the fifth day. There was no statistically significant difference between groups at preoperation and each time point of postoperation (P > 0.05). (3) The results suggest that the tranexamic acid can effectively reduce the dominant and recessive blood loss in patients with the intertrochanteric fracture, and it is safe and effective.

OBJECTIVE: To compare the flow-mediated dilatation (FMD) among the newly diagnosed impaired glucose tolerance (IGT), type 2 diabetes mellitus (T2DM), and the normal controls (NC) and to analyze relevant factors under different glucose levels. METHODS: The study included IGT (n=34), DM1 (n=52), DM2 (n=33) and NC (n=25). Levels of fasting plasma glucose (FPG), 2-hour postprandial plasma glucose (PPG), fasting insulin (FINS), 2-hour postprandial insulin (PINS), triglyceride (TG), total cholesterol (TC), and hemoglobin A1C (HbA1C) were determined in all participants. High resolution ultrasound examining FMD was performed to measure vascular endothelial function subsequently. RESULTS: There was statistically significant difference between IGT, DM, HG and NC group in FMD (P=0.008). Partial correlation analysis found that a significant negative correlation existed between FMD and homeostasis model assessment-index (HOMA-IRI), difference of plasma glucose (DPG), FPG and PPG (P<0.01), and a negative correlation between FMD and HbA1C (P<0.05). Setting FMD as dependent variable to conduct multiple linear stepwise regression, in IGT group it was the waist/hip ratio (WHR) and HOMA-IRI that entered the regression equation; in DM1 group it was HOMA-IRI, PPG and DPG that entered the regression equation; in DM2 group it was FPG and HOMA-beta that entered the regression equation. CONCLUSION There exists a flow-mediated vasodilatation dysfunction in patients of newly diagnosed IGT and T2DM. Effect of relevant factors on FMD differs with different glucose levels.

BACKGROUNDRheumatoid arthritis (RA) is an autoimmune disease characterized by chronic inflammation at the synovial membrane. Although great progress has been made recently in exploring the etiology and pathogenesis of RA, its molecular pathological mechanism remains to be further defined and it is still a great challenge in determining the diagnosis and in choosing the appropriate therapy in early patients. This study was performed to screen candidate RA-associated serum proteins by comparative proteomics to provide research clues to early diagnosis and treatment of RA.

METHODSSera isolated from 6 RA patients and 6 healthy volunteers were pooled respectively and high-abundance proteins were depleted by Plasma 7 Multiple Affinity Removal System. The protein expression profiles between the two groups were then compared by two-dimensional gel electrophoresis (2-DE) and the proteins over/under-expressed by more than 3-fold were identified by mass spectrometry analysis. To validate the differential expression levels of the identified proteins between the two groups, ELISA was performed in two of the identified proteins in individual sera from 32 RA patients and 32 volunteers.

RESULTSEight proteins which over/under-expressed in sera of RA patients were identified. Among them, chain A of transthyretin (TTR) was under-expressed, while serum amyloid A protein, apolipoprotein A (ApoA)-IV, ApoA-IV precursor, haptoglobin 2, ceruloplasmin (Cp), immunoglobulin superfamily 22 and HT016 were over-expressed. ELISA test confirmed that Cp expressed remarkably higher while TTR obviously lower in RA group compared with volunteer group.

CONCLUSIONThere were 8 identified proteins differentially expressed between RA group and volunteer group, which might be candidate RA-associated proteins and might be promising diagnostic indicators or therapeutic targets for RA.

OBJECTIVETo observe the effectiveness of MEBO in the treatment of burn patients with burn area over 50% TBSA.

METHODSTwo hundred and ninety-eight patients hospitalized in our hospital from May of 1991 to December of 2003 with burn area over 50% TBSA, who had MEBO treatment before hospitalization, were enrolled in the study as the experiment (E) group. Another group of 300 burn patients with burn area over 50% TBSA that treated with SD-Ag cream were enrolled in the study as the control (C) group. Bacterial culture results, major changes in injury and mortality were compared between the two groups.

RESULTSThere were 1 506 bacteria strains isolated from wounds in E group, and 9 main changes in injury (1679 cases) occurred with 20.8% mortality in this group. There were 353 bacteria strains isolated, with occurrence of 9 changes in injury (518 cases) and 4.7% mortality in the SD-Ag group.

CONCLUSIONMEBO is much less effective for the treatment of the burn patients with large burn area compared with SD-Ag cream treatment.
