OBJECTIVETo evaluate the short-term efficacy and safety of Bushen Shuji Granule (BSG) in treating ankylosing spondylitis (AS) patients.

METHODSA prospective randomized controlled clinical trial was carried out in 62 active stage AS patients with Shen deficiency Du-channel cold syndrome (SDDCS), who were randomly assigned to the BSG group (treated with BSG) and the control group (treated with Celecoxib Capsule). Twelve weeks consisted of one therapeutic course. Therapeutic effects were evaluated by ASAS20 and ASAS40 (set by Assessments in Ankylosing Spondylitis working group) , BASDA150, Chinese medical (CM) syndrome efficacy evaluation standards. BASDAI, the Bath Ankylosing Spondylitis Functional Index (BASFI), the Bath AS Metrology Index (BASMI), scores for spine pain, scores for pain at night, patient global assessment (PGA) , erythrocyte sedimentation rate (ESR) , and C reactive protein (CRP) were observed before and after treatment.

RESULTSAfter three-month treatment by BSG, ASAS20 standard rate was 63. 33% (19/30 cases) in the BSG group and 66.67% (20/30 cases) in the control group with no significant difference between the two groups (χ2 = 0.073, P > 0.05). The efficacy for CM syndromes was 70.00% (21/30 cases) in the BSG group, higher than that in the control group [40.00% (12/30 cases), χ2 = 5.455, P < 0.05]. Scores for CM syndromes, BASDAI, night pain index, spinal pain index, PGA, CRP were improved in the BSG group (P < 0.05, P < 0.01). The incidence of adverse events in the BSG group was lower than that of the control group.

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.

AIMTo observe the dynamic expression of ERK1 in fibrotic rat liver.

METHODSThe rat hepatic fibrosis was induced by bile duct ligation (BDL). Histopathological changes were evaluated by hematoxylin and eosin staining, and by Masson's trichrome method. ERK1 mRNA in liver was determined by reverse transcription-polymerase chain reaction (RT-PCR), while the distribution of ERK1 was assessed by immunohistochemistry. ERK1 protein was detected by using Western blotting analysis.

RESULTSWith the development of hepatic fibrosis, the positive cells of ERK1 increased a lot, they were mainly distributed at portal ducts, fiber septa and around the bile ducts, vascular endothelial cells and perisinusoidal cells. Western blotting analysis results displayed that the expression of ERK1 protein were up-regulated with model course, and its levels were the highest at week 4 after operation, achieving to 3.9-fold of that in normal rat liver. ERK1 mRNA expressed in normal rat livers as well, they were up-regulated at day 2 after BDL and its level was the highest at week 4 after BDL.

CONCLUSIONThese data suggest that the expression of ERK1 and its mRNA can be increase greatly in fibrotic rat liver.

OBJECTIVETo evaluate the clinical efficacy and safety of bushen quhan zhiwang decoction (BQZD) combined methotrexate (MTX) in treating rheumatoid arthritis (RA).

METHODSA prospective, randomized controlled study was carried out. RA patients of Shen deficiency and cold invading syndrome in the treatment group (120 cases) were treated with BQZD and MTX (10 mg/week), while those in the control group (120 cases) were treated with MTX (10 mg/week) alone. The therapeutic course for all was 24 weeks. The efficacy and safety indices were evaluated at the baseline and 24 weeks after treatment, including clinical signs and symptoms, condition assessment, Health Assessment Questionnaire (HAQ), disease activity index 28 (DAS28), laboratory parameters of erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP), safety indicators, and Chinese medical syndrome integrals.

RESULTSThe total effective rate was 80. 0% in the treatment group, better than that of the control group (66.7%), showing statistical difference (P <0.01). In the two groups significant improvement of clinical signs and symptoms, ESR, CRP, visual analogue scale (VAS) by both physicians and patients, HAQ, DAS28, and Chinese medical syndrome integrals after treatment were shown (P <0.01). Better effects were obtained in the treatment group in lessening tender joint numbers and swollen joint numbers, VAS by both physicians and patients, DAS28, and Chinese medical syndrome integrals (P < 0.05). Besides, adverse reactions occurred less in the treatment group than in the control group (P < 0.05).

CONCLUSIONSBQZD had roles in relieving symptoms, improving joint functions, signs, ESR, and CRP. It was an effective herb for RA patients of Shen deficiency and cold invading syndrome. It could enhance the efficacy and reduce adverse reactions of MTX through synergistic effects with MTX.

OBJECTIVETo study hepatic NF-κB level following endotoxemic liver injury, and its relationship with hepatic TNF-α and IL-6 levels in young rats.

METHODSForty 18-day-old rats were randomly assigned to a normal control and an endotoxemia group. Endotoxemia was induced by lipopolysaccharide injection (LPS, 5 mg/kg). The endotoxemia group was subdivided into four groups sampled at 2, 6, 12 and 24 hrs after LPS injection (n=8 each). Pathological changes in liver cells were observed under a light microscope. TNF-α and IL-6 levels in liver tissue homogenates were measured using ELISA. Reitman-Frankel was used to measure serum ALT concentrations. NF-κB activation level in liver tissues was detected by immunohistochemistry.

RESULTSLiver tissue injury was the most obvious 6 hrs after LPS injection under the light microscope, and the damage rating of liver tissues was significantly higher in the endotoxemia group than that in the normal control group at all time points (P<0.05). ALT levels in the endotoxemia group were significantly higher than those in the normal control group 6, 12 and 24 hrs after LPS injection (P<0.05). NF-κB p65 protein expression in liver cells (percentage of nuclear positive cells) in the endotoxemia groups was significantly higher than that in the normal control group (P<0.05). TNF-α and IL-6 levels in liver tissue homogenates in the endotoxemia groups were significantly higher than those in the normal control group 6 and 12 hrs after LPS injection (P<0.05).

CONCLUSIONSEndotoxemia can cause liver injury, resulting in liver cell damage and changes in liver function. NF-κB activation is involved in endotoxemic liver injury which may be mediated by inflammatory cytokines TNF-α and IL-6 synthesis.
