AIM: To assess the effect of curcumin in hypothalamic paraventricular nucleus (PVN) and mean arterial pressure so as to explore the central mechanism of hypertension. METHODS: Sixty Sprague-Dawley rats which body weights between 170 and 190 grams fed with a normal salt (0.3% NaCl) or a high salt (8% NaCl) diet for 6 weeks. Meanwhile half of each team received curcumin administration or vehicle by intragastric administration. Mean Arterial pressure was measured noninvasively via tail-cuff instrument and their recording system. The PVN tissue samPles were collected and stored at −80 °C for later analyses. We performed the following experimental procedures: Western blot analysis, immunofluorescence, immunofluorescence and statistical analysis. RESULTS:The average arterial blood Pressure of rats in the high-salt diet group was significantly reduced after 6 weeks of curcumin intervention. The levels of NOX2, NOX4, TLR4, MyD88, IL-6, IL-1β, MCP-1 and ROS in the long-term high-salt diet grouP were significantly higher after curcumin intervention. CONCLUSION:Curcumin can improve blood pressure in hypertensive rats induced by long-term high salt, the mechanism may be related to the imProvement of oxidative stress and inflammatory cytokines in the paraventricular nucleus of the hypothalamus.

With the increasing incidence rates of metabolic diseases such as obesity and type 2 diabetes, the incidence rate of nonalcoholic fatty liver disease (NAFLD) has also gradually increased year by year. NAFLD has complex underlying pathogeneses which have not yet been fully clarified. As the carrier of intercellular communication, exosomes play an important role in the development and progression of liver diseases. This article summarizes the mechanism of action of exosomes in the pathogenesis of NAFLD and their effect on lipid metabolism, insulin resistance, liver inflammation, and fibrosis, and it is pointed out that exosomes have great potential in the diagnosis and treatment of diseases, which will be the focus of future research.

Objective To investigate the prevention effects of antithrombotic pressure pump combined with graduated compression stockings (GCS) on incidence of postoperative lower extremity deep venous thrombosis (LEDVT) in breast cancer patients. Methods A total of 363 cases of breast cancer patients after operation were divided into routine care group (124 cases) according to the method of random number table, pressure group (127 cases) and combined treatment group (112 cases). The routine care group received conventional LEDVT ankle pump exercises. The pressure group used GCS besides the routine intervention. The combined group received GCS and antithrombotic pressure pump besides the routine intervention. Then the levels of thrombosis markers, D-dimers,platelets, and incidences of LEDVT were examined in the three groups. Results Before operation, no significant differences between the levels of prothrombin time (PT), activated partial prothrombin time (APTT), thrombin time (TT), fibrinogen, plasma D-dimer and platelets (P>0.05). After operation, the levels of PT, APTT, TT, fibrinogen, plasma D-dimer and platelets in three groups were (10.22 ± 0.76) s, (27.24 ± 3.68) s, (14.60 ± 0.88) s, (2.94 ± 0.59) mg/L, (0.31 ± 0.21) mg/L, (288.48 ± 71.29) × 109/L, (10.73 ± 0.79) s, (27.35 ± 2.54) s, (14.71± 1.76) s, (4.12±1.09) mg/L, (0.46±0.38) mg/L, (284.26±70.98) ×109/L and (11.11±0.64) s、(28.52± 2.74) s, (14.33± 1.02) s, (4.42±1.20) mg/L, (0.35±0.33) mg/L, (258.79±62.35) ×109/L, respectively. There was significant difference among these groups (F=5.71-87.31, P<0.01). The differences on PT, APTT, fibrinogen and D-dimers between combined treatment group and routine care group were statistically significant (P<0.05). The differences on PT, fibrinogen and platelets between combined treatment group and pressure group were statistically significant (P<0.05). The differences on PT, APTT, fibrinogen and D-dimers between routine care group and pressure group were statistically significant (P<0.05). Through one months of follow-up, the incidence of LEDVT in routine care group, pressure group and combined treatment group were 12.10％(15/124),3.15％(4/127),0.89％(1/112), respectively. There was significant difference among these groups (χ2=16.279,P<0.01). Conclusions The application of antithrombotic pressure pump combined with GCS significantly improves the postoperative hypercoagulable states in breast cancer patients. The combined treatment reduces the incidence of LEDVT without bleeding risk. Therefore, antithrombotic pressure pump combined with GCS is recommended for clinical use in the postoperative breast cancer patients.

Objective: To explore the clinical features of patients with synchronous lymphoma and carcinoma. Methods: The clinical data of 17 patients with Synchronous lymphoma and carcinoma from February 2012 to October 2017 were analyzed retrospectively. Results: Among 17 patients of lymphoma, 1 case HL, 2 cases B-NHL, 6 cases MZBL, 3 cases DLBCL, 1 case mantle cell lymphoma (MCL) , 3 cases NK/T- cell lymphoma, 1 case anaplastic large cell lymphoma(ALCL). In terms of 17 patients with carcinoma, 3 cases esophageal carcinoma, 3 cases gastric carcinoma, 2 cases colorectal carcinoma, 7 cases thyroid carcinoma, 1 case hepatocellular carcinoma and lung cancer. Up to 15 patients received operation, and some of them combined with chemotherapy, radiotherapy and autologous transplant. Follow-up analysis showed that 3 cases was undergoing treatment, 2 cases lost follow-up, 4 cases died, 3 cases achieved CR, 3 cases remained to be at SD, and 2 cases assessed for progression or recurrence. Conclusion The relationship between lymphoma and carcinoma was under discussion, patients with synchronous lymphoma and carcinoma were not unusual. We herein should raise awareness to avoid misdiagnosis.

Objective To evaluate the value of localization diagnosis of 1H-magnetic resonance spectroscopy (MRS) in the patients with structural MRI-negative temporal lobe epilepsy (TLE) based on the results of localization diagnosis of electroencephalogram (EEG) in patients with TLE without lesion.Methods Thirty-three patients with MRI-negative TLE and 33 age-and sex-matched healthy control subjects underwent MRS and took the side localized by scalp/video EEG as standard,to evaluate the value of N-acetyl-L-aspartic acid (NAA)/creatine (Cr),NAA/(Cr + choline (Cho)) in the localization diagnosis of TLE.Results There was no significant difference in NAA/Cr,Cho/Cr and NAA/(Cr + Cho) in bilateral hippocampi of 33 healthy controls,and the mean values of them in bilateral hippocampi were regarded as normal values.The NAA/Cr and NAA/(Cr + Cho) ratios were significantly decreased in both sides of the hippocampi ipsilateral and contralateral to the seizure side.Taking NAA/Cr and NAA/(Cr +Cho) as an index to localize respectively and comparing with the localization diagnosis of EEG,spectral anomalies were found in 28 cases and 29 cases respectively,and the abnormal rate reached 85％ and 88％.The localization diagnosis of 17 and 18 cases was consistent with the EEG,the rate being 52％ and 55％ respectively,but 12％ (4/33) and 18％ (6/33) were opposite.There were 36％ (12/33) and 27％ (9/33) cases who could not be localized.The localization diagnosis results by NAA/Cr and NAA/(Cr +Cho) were not significantly different.Conclusions The existence of mirror-image foci may be the main reason of the failure of localization diagnosis.1H-MRS has higher value for localization of TLE foci,and combining 1H-MRS with other techniques can further improve the accuracy and reliability of localizing the epileptic foci in patients with TLE.Compared with EEG in the diagnosis of TLE,there are no significant differences in the localization diagnosis of TLE by NAA/Cr and NAA/(Cr + Cho),which can all be the standard indices of localization diagnosis.
