AIMTo study the sensitizing effect of acemetacin (ACE) on the weak chemiluminescent (CL) reaction of KMnO4 with sulfite and establish a fast and convenient method for CL detection of ACE.

METHODSUsing the sensitizing effect of ACE on KMnO4-Na2SO3 system and flow injection technique to determine the concentration of ACE.

RESULTSUnder optimal conditions, the CL intensity of 1.0 x 10(-2) mol x L(-1) H3PO4 - 5.0 x 10(-5) mol x L(-1) KMnO4 - 4.0 x 10(-4) mol x L(-1) Na2SO3 was proportional to the concentration of ACE ranging from 1.0 x 10(-7) to 1.0 x 10(-5) mol x L(-1). The detection limit of ACE was 6.9 x 10(-8) mol x L(-1) at 3sigma. Satisfactory results were obtained for determination of ACE at 2.5 x 10(-6) mol x L(-1).

CONCLUSIONThe present method showed good precision, high sensitivity and selectivity and could be used for fast and convenient detection of ACE. It would be of significance to the clinical and pharmacological study of acemetacin.

OBJECTIVETo evaluate the analgesic efficacy and systemic anti-inflammation of preoperative cyclooxygenase-2 nonsteroidal antiinflammatory drug, rofecoxib, after total knee replacement (TKR).

METHODSThirty patients underwent elective knee replacement were randomly given oral rofecoxib 25 mg (group RE, n = 15) or placebo (group E, n = 15) 1 hour prior to surgery. All patients received epidural combined isoflurane anesthesia during surgery and patient-controlled epidural analgesia after surgery for 72 hrs (0.1 mg/ml morphine + 1.2 mg/ml bupivacaine + 0.02 mg/ml droperidol). Modified verbal rate scale was used to evaluate postoperative pain intensity. The outcomes included pain scores during rest and movement of knee joints and analgesia satisfaction. Daily morphine consumption was recorded. Circulation leucocyte and serum cytokine concentrations (including interleukin 6, interleukin 8, interleukin 10, Tumor necrosis factor-alpha) were determined before surgery, at the end of surgery, 2 h, 6 h, 12 h, 24 h and 48 h after surgery in two groups using RIA. The amount of intraoperative blood loss and postoperative drainage from the knees were measured.

RESULTSThe pain scores were significantly less in the group RE than in group E during rest and knee joints movement on the first and second postoperative day, with an improvement in total analgesia satisfaction (P < 0.05). The mean dose of morphine for first 24 h was (8.1 +/- 1.5) mg in the E group and (6.8 +/- 0.7) mg in the RE group (t = -2.71, P < 0.01). Leucocyte and neutrophil counts were much higher in group E than in group RE at 12 h, 24 h post-operatively (P < 0.05). Serum TNF-alpha concentration was significantly lower in group RE than group E at the end of surgery, 6 h, 12 h postoperatively, as well as IL6 at 48 h, IL8 at 24h after surgery (P < 0.05). There were no significant differences in respect to the amount of intraoperative and postoperative blood loss between two groups (P > 0.05).

CONCLUSIONPreoperative cyclooxygenase-2-specific nonsteroidal anti-inflammatory drug rofecoxib increases analgesia satisfaction, reduces opioid requirement and demonstrates a systemic anti-inflammatory effect after TKR.

OBJECTIVEA comparative proteomic approach was used to identify and analyze proteins relevant to metastasis of hepatocellular carcinoma (HCC).

METHODSProteins extracted from 12 liver tumor tissue specimens (6 with metastases and 6 without) were separated by two-dimensional gel electrophoresis (2-DE). Comparative analyses of 2-DE protein patterns between the two groups were done using computerized image analysis. Selected proteins exhibiting statistically significant alternations were identified by mass spectrometry. Immunohistochemistry, Western blotting and RT-PCR were performed to examine the expressions of the candidate proteins.

RESULTS16 proteins including HSP27, S100A11, CK18 were identified using mass spectrometry, which were related to cell mobility, signal transduction, and energy metabolism respectively. Of these, HSP27 was found to be uniquely over-expressed in 2-DE maps of all metastatic HCCs when compared to the non-metastatic HCC tissues. Immunohistochemistry and Western blotting of HCC tissues confirmed this difference while RT-PCR did not.

CONCLUSIONThere are different proteins working together that affect the metastasis of HCCs. The overexpression of HSP27 may serve as a biomarker for early detection and therapeutic targets to the metastatic phenotype of HCC. The role of HSP27 in HCC metastasis warrants further investigation.

OBJECTIVESTo investigate the possibility and efficacy of vasoligation and deferent vein ligation in treating and preventing benign prostatic hyperplasia(BPH).

METHODS40 male pooches were divided into A, B, C and D groups randomly. Each group has 10 pooches group A and B were made into the model of BPH. Two years later, the pooches in group A and C accepted the operation of vasoligation and deferent vein ligation on both sides. Group B and D only accepted the operation of dissection and relieving its deferent duct. Then continuing to feed the 40 pooches after the operation, they were killed another two years later. After taking out their prostates and calculating their volume and weight, the sections of the prostates were checked by microscope to observe their histology and pathology changes.

RESULTSThere were significant differences of weight and volume as well as the changes of histology and pathology between group A and group C (P < 0.01). It was the same with group B and D (hyperplasia changes).

CONCLUSIONSVasoligation and deferent vein ligation before benign prostatic hyperplasia at pooches grow-up stage can reduce the extent of BPH at old age, and treatment after benign prostatic hyperplasia can make prostatic tissue appear different degrees of atrophy.

BACKGROUND: MAVERIC (Mitral Valve Repair Clinical Trial) validates the safety and efficacy of the ARTO system. We here report the first two successful cases of utilizing the ARTO system in patients with symptomatic heart failure (HF) with functional mitral regurgitation (FMR) in Asia. METHODS: Two patients, aged 70 and 63, had severe HF with FMR. Transesophageal echocardiography confirmed that the left ventricular ejection fractions were less than 50% with severe mitral regurgitation (MR) in both patients. Optimizing drug treatment could not mitigate their symptoms. Therefore, we used the ARTO system to repair the mitral valve for these patients on March 5 and 6, 2019, respectively. RESULTS: Mitral valve repairs using the ARTO system were successfully performed under general anaesthesia for these two patients. MR was decreased immediately after the procedures in both patients. The 30-day and 3-month transthoracic echocardiography (TTE) revealed a moderate to severe MR in both patients, and the New York Heart Association (NYHA) scales were also partially improved. CONCLUSION The first two cases in Asia indicate that the ARTO system is feasible for patients with heart failure with FMR, and the patient selection appears to be crucial.
