Objective To compare the value of conventional ultrasound,hydrosonography and double-contrast enhanced ultrasound in the display capacity of periampullary carcinoma and its relationship with the surrounding tissue.Methods A total of 18 patients with the periampullary carcinoma were diagnosed pathologically or by endoscopic biopsy.Each patient had three imaging modalities by conventional ultrasound,hydrosonography and double-contrast enhanced ultrasound.The display capacity and the relationship between the mass and surrounding tissue were compared with three modalities.Results The display rates of limpid visibilities of carcinoma on conventional ultrasound,hydrosonography and double-contrast enhanced ultrasound were 16.7%(3/18),22.2%(4/18) and 94.4%(17/18),respectively;The display rates of duodenum protrusion on three modalities were 0(0/18),38.9% (7/18) and 72.2% (13/18),respectively,with significant differences among conventional ultrasound,hydrosonography and double-contrast enhanced ultrasound.The double-contrast enhanced ultrasound showed two cases of peripheral vascular invasion and one case of intrahepatic metastasis.Conclusion The double-contrast enhanced ultrasound can increase the display capacity of periampullary carcinoma as a new diagnostic modality for periampullary carcinoma.

BACKGROUND:Increasing reports have focused on the application of tranexamic acid to reduce bleeding during total knee arthroplasty, but its usage method remains controversial.
OBJECTIVE:To explore the impact of topical articular application of tranexamic acid and intravenous application of tranexamic acid on blood loss during primary unilateral total knee arthroplasty.
METHODS:According to randomized control ed principle, 90 patients who received unilateral total knee arthroplasty in the Tengzhou Central People’s Hospital from October 2013 to December 2014 were enrol ed in this study, and randomly assigned to intravenous injection group and topical injection group (n=45). Patients in the intravenous injection group were given tranexamic acid by intravenous injection (10 mg/kg, maximum 1.2 g) during the induction of anaesthesia. Patients in the topical injection group were given intraarticularly tranexamic acid (2 g dissolved in 50 mL physiological saline) before articular capsule suture and after prosthesis fixation. Drainage amount after replacement, hemoglobin and hematocrit on the next day after replacement, and the number of blood transfusion population were compared between the two groups. Simultaneously, clinical symptoms of pulmonary embolism and deep vein thrombosis in the lower limb were observed. If necessary, lower extremity vascular Doppler ultrasound was conducted.
RESULTS AND CONCLUSION:No significant differences in drainage amount after replacement, hemoglobin and hematocrit on the next day after replacement, the number of blood transfusion population, and the proportion of blood transfusion were detected between the two groups (P>0.05). No deep vein thrombosis was found in the lower limbs at 14 days after replacement in both groups. These findings confirm that compared with intravenous systemic application, periarticular topical application of tranexamic acid during total knee replacement could obtain identical effects on reducing blood loss and blood transfusion after surgery, and could avoid relevant complications of intravenous application of tranexamic acid.

In order to evaluate the effect and mechanism of the mulberry leaf alkaloid, flavones, and polysaccharide intervention on diabetes, the overall metabolite profiling characteristics for the plasma of diabetic mouse was performed by using an ultra-performance liquid chromatography/electrospray-tandem mass spectrometry (UPLC-ESI-MS). The 8 potential biomarkers were found in diabetic mice plasma based on the data of MS/MS characteristics obtained from the UPLC-OrbitrapMS analysis, which mainly involved in sphingolipids, amino acid metabolic pathway. The principal component analysis showed that the normal group and model group were obviously distinguished and implied that metabolic disturbance was happened in diabetic mice plasma. The extracts of mulberry leaf flavonoids, polysaccharide, alkaloid had exhibited the effects of callback function for diabetic mice through regulating the amino acid metabolism and sphingolipid metabolism.

BACKGROUND: Reducing perioperative blood loss in total hip arthroplasty is a hot topic for joint surgeons. Both intravenous infusion and intra-articular injection of tranexamic acid significantly reduce perioperative blood loss, blood transfusion volume, and need for blood transfusion in patients undergoing total hip arthroplasty. However, differences between the intravenous and intra-articular methods are not clear.OBJECTIVE: To evaluate the effects of these two tranexamic acid administration methods on perioperative blood loss in patients undergoing total hip arthroplasty.METHODS: We are conducting a prospective, single-center, open-label, randomized, controlled clinical trial at the Tengzhou Central People's Hospital, China. Ninety patients undergoing unilateral total hip arthroplasty have been randomized into three groups. In the intravenous infusion group (n=30), 15 mg/kg tranexamic acid diluted in 100 mL physiological saline was infused intravenously at the beginning of surgery and 20 mL of physiological saline was injected intra-articularly after deep fascia suturing. In the intra-articular injection group (n=30), 100 mL of physiological saline was infused intravenously at the beginning of surgery and a mixture of 1.5 g tranexamic acid and 20 mL physiological saline was injected intra-articularly after deep fascia suturing. In the control group (n=30), 100 mL of physiological saline was infused intravenously at the beginning of surgery and 20 mL of physiological saline was injected intra-articularly after deep fascia suturing. The primary outcome is hidden blood loss at 1 and 3 days postoperatively. The secondary outcomes are visible blood loss, need for blood transfusion, and mean blood transfusion volume intraoperatively and on days 1 and 3 postoperatively. Other outcomes are the incidence of adverse reactions and complications within 3 months of surgery. The study protocol has been approved by the Ethics Committee of Tengzhou Central People's Hospital of China, approval number 2015-026. All protocols will be performed in accordance with the Ethical Principles for Medical Research Involving Human Subjects in the Declaration of Helsinki. Written informed consent was provided by each patient and their family members after they indicated that they fully understood the treatment plan.DISCUSSION: This trial was designed in April 2015. Cases were collected in July 2015. Data analysis will be finished in December 2017. This study is designed to investigate the effects of intravenous infusion versus intra-articular injection of tranexamic acid on perioperative blood loss in patients undergoing total hip arthroplasty to determine the more effective mode of administration.

OBJECTIVETo analyze the effects of long-term microwave exposure on hippocampal structure and function in the rat.

METHODSExperiments were performed on 184 male Wistar rats (three exposure groups and a sham group). Microwaves were applied daily for 6 min over 1 month at average power densities of 2.5, 5, and 10 mW/cm2. Learning and memory abilities were assessed by Morris water maze. High performance liquid chromatography was used to detect neurotransmitter concentrations in the hippocampus. Hippocampal structures were observed by histopathological analysis.

RESULTSFollowing long-term microwave exposure there was a significant decrease in learning and memory activity in the 7 d, 14 d, and 1 m in all three microwave exposure groups. Neurotransmitter concentrations of four amino acids (glutamate, aspartic acid, glycine, and gamma-aminobutyric acid) in hippocampus were increased in the 2.5 and 5 mW/cm2 groups and decreased in the 10 mW/cm2 group. There was evidence of neuronal degeneration and enlarged perivascular spaces in the hippocampus in the microwave exposure groups. Further, mitochondria became swollen and cristae were disordered. The rough endoplasmic reticulum exhibited sacculated distension and there was a decrease in the quantity of synaptic vesicles.

CONCLUSIONThese data suggest that the hippocampus can be injured by long-term microwave exposure, which might result in impairment of cognitive function due to neurotransmitter disruption.
