Malignant mesothelioma is a highly malignant disease that most often occurs in the pleural cavity, followed by the peritoneum and pericardium. Malignant peritoneal mesothelioma (MPM) accounts for 10%-15% of all mesothelioma. The most important risk factor for MPM is exposure to asbestos. MPM has no specific clinical symptoms, imaging and histopathology are critical for the diagnosis. There are currently no generally accepted guidelines for curative treatment of MPM. The patient mainly presented with abdominal pain, abdominal distension and discomfort. Due to extensive omentum metastasis, no further surgical treatment was performed. Pemetrexed combined with cisplatin chemotherapy was given for 2 cycles, and the patient is still alive.

Objective:To explore and compare the clinical efficacy of lyophilized recombinant human brain natriuretic peptide (Lrh-BNP) and dobutamine (Dob) in the treatment of patients with acute heart failure (AHF) and impacts on the plasma galectin (Gal)-3,Cystatin C (CysC) and endothelin (ET-)-1 levels.Methods:114 cases of patients with AHF in our hospital from February 2015 to February 2017 were selected as the research objectives and randomly divided into two groups.Dob group was treated by Dob,while Lrh-BNP group was treated by Lrh-BNP.The cardiac function parameters,plasma Gal-3,CysC,ET-1 levels before and after treatment,clinical comprehensive efficacy and incidence of adverse reactions were compared between two groups.Results:The FS,LVEF levels of both groups at 72 hours after treatment were significantly higher than those before treatment (P＜0.01),but the LVEDD,plasma Gal-3,CysC,ET-1 levels were obviously decreased (P＜0.01),the index mentioned above of Lrh-BNP group improved more significantly than those of the Dob group(P＜0.01).The overall effective rate of Lrh-BNP group was 89.5 ％,which was significantly higher than that of the Dob group (73.7％,P＜0.05).No significant difference was found in the incidence of adverse reaction between two groups(P＞0.05).Conclusion:Lyophilized recombinant human brain natriuretic peptide was more effective in the treatment of AHF than Dobutamine with equal safety,which might be related to the decrease of plasma Gal-3,CysC,ET-1 levels.

Objective To investigate the characteristic of the B-mode ultrasonography and the color Doppler flow imaging diagnosis for intraocular cysticercosis.Methods Eleven eyes of 1 1 patients diagnosed of intraocular cysticercosis clinically and confirmed by operation and pathology were retrospectively studied. Their B-mode ultrasonography and color Doppler flow imaging were analyzed.Surgery diagosis was also reviewed.Results Among 1 1 eyes of 1 1 patients,intravitreal cysticercus presented in 7 cases (7 eyes),and 4 cases (4 eyes)diagnosed of subretinal cysticercus.Intraocular cysticercosis showed a round or oval vesicle-like echogenic mass in the vitreous body or under the retina,and the high-level echo spot in it was the scolex. Some dot and stripe echo and retinal detachment also appeared in the vitreous cavity with vitreous inflammation.The blood flow signal was detected in retinal detachment with color Doppler flow imaging. Conclusions Ultrasonography is extremely useful in the diagnosis of intraocular cysticercosis and the findings can be pathognomonic.

A global quality control method based on high performance liquid chromatography (HPLC) coupled with diode array detection (DAD), single quadrupole mass spectrometry (MS) and time-of-flight mass spectrometry (TOFMS) was developed for simultaneous determination of seven major components (mangiferin, neomangiferin, timosaponin E1, timosaponin E, timosaponin BⅡ, timosaponin BⅢ, and timosaponin AⅢ) and identification of most components in extracts of Rhizoma Anemarrhenae (RA). HPLC analysis was performed on an Agilent SB-C18 column (4.6 mm×150 mm, 5 μm) by gradient elution using acetonitrile and water-acetic acid(100∶0.05, v/v) as the mobile phase. Seven major components in RA were successfully separated. This quantitative method was fully validated in respect of the following performance criteria: linearity, precision, repeatability, stability, accuracy, limits of detection (LOD) and quantification (LOQ). A formula database of known compounds in RA was established, against which, most of the reported components in this herbal extract were identified effectively based on the extract masses acquired by TOFMS. This qualitative and quantitative method was successfully used to analyze the components in 10 batches of RA samples collected from different regions in China. This global quality control method, which consisted of HPLC-DAD-MS assay of seven major components and unambiguous identification of nineteen components, is suitable for routine quantification and comprehensive quality control of RA.

Objective To investigate the effect of mentalization based treatment on the negative emotion such as anxiety,depression and chronic drug craving among methamphetamine addicts.Methods Totally 612 methamphetamine addicts in 6 compulsory isolated detoxification center of Liaoning served as the study subjects and randomly divided into the experimental group (mentalization based treatment group) and control group,306 cases in each group.The Beck Anxiety Inventory (BAD,Beck Depression Inventory (BDI) and the Drug Craving Inventory were used to evaluate the anxiety,depression and chronic craving in the two groups.Results The scores of BAI,BDI and Drug Craving Inventory after mentalization base treatment in the experimental group were decreased compared with those of before intervention (P＜0.05).The declining trend of the scores of BAI,BDI and Drug Craving Inventory after intervention in the experimental group were more significant than that in the control group (P＜0.05).Conclusion The mentalization based treatment can improve the negative emotions such as anxiety and depression to some extent,and reduces the chronic drug craving among methamphetamine drug addicts.

Objective:To discuss the characteristics of ultrasound diagnosis of optic disc capillary hemangioma.Methods:The study analyzed retrospectively 7 cases of optic disc capillary hemangioma diagnosed in the Beijing Tongren Hospital from 2015 to 2018. The size, morphology, internal echo, and secondary changes of the lesion were analyzed during ultrasound examination.Color Doppler flow imaging was used to check the blood flow in the lesion.Results:Pre-optic disc occupying lesions could be detected in the ultrasound images of the 7 cases. Lesion size: average base diameters (5.39±1.90)mm×(4.79±1.28)mm, average height (3.61±1.37)mm. Lesion morphology: 5 cases were round, and 2 cases were irregular. Echo within the lesion: 3 cases had medium echo inside the lesion, and 4 cases had high echo inside the lesion. Internal echo characteristics: 5 cases had uniform echo, and 2 cases had uneven echo. Secondary changes: 6 cases had secondary retinal detachment and vitreous opacity, and 1 cases was accompanied by retinal hemangioma in other parts. In all cases, blood flow signals could be detected inside the space-occupying lesions, which were in the form of branches, stripes or spots, and the blood flow spectrum showed a parallel spectrum of arteries and veins.Conclusions:Ultrasound examination of optic disc capillary hemangioma has certain characteristics, which can provide a valuable follow-up basis for clinical diagnosis.

Background/Aims: Irritable bowel syndrome (IBS) is a prevalent functional gastrointestinal disease characterized by recurrent abdominal pain and bowel dysfunction. However, the majority of previous neuroimaging studies focus on brain structure and connections but seldom on the inter-hemispheric connectivity or structural asymmetry. This study uses multi-modal imaging to investigate the abnormal changes across the 2 cerebral hemispheres in patients with IBS. Methods: Structural MRI, resting-state functional MRI, and diffusion tensor imaging were acquired from 34 patients with IBS and 33 healthy controls. The voxel-mirrored homotopic connectivity, fractional anisotropy, fiber length, fiber number, and asymmetry index were calculated and assessed for group differences. In addition, we assessed their relevance for the severity of IBS. Results: Compared with healthy controls, the inter-hemispheric functional connectivity of patients with IBS showed higher levels in bilateral superior occipital gyrus, middle occipital gyrus, precuneus, posterior cingulate gyrus, and angular gyrus, but lower in supplementary motor area. The statistical results showed no significant difference in inter-hemispheric anatomical connections and structural asymmetry, however negative correlations between inter-hemispheric connectivity and the severity of IBS were found in some regions with significant difference. Conclusions The functional connections between cerebral hemispheres were more susceptible to IBS than anatomical connections, and brain structure is relatively stable. Besides, the brain areas affected by IBS were concentrated in default mode network and sensorimotor network.

Objective To analyze the correlation between plasma Pannexin-1(Panx-1)level and no-reflow after percutaneous coronary intervention(PCI)in patients with ST-segment elevation my-ocardial infarction(STEMI).Methods A prospective trial was performed on 218 STEMI patients who underwent PCI in our hospital from January 2019 to December 2021.According to the blood flow classification of myocardial infarction thrombolysis(TIMI)after PCI,they were divided into normal reflow group(110 cases),slow reflow group(69 cases)and no reflow group(39 cases).The plasma Panx-1 level was determined by ELISA,and the levels of P-selectin,activated glyco-protein Ⅱ b/Ⅲ a(aGP Ⅱ b/Ⅲ a)and platelet-leukocyte aggregates(PLA)were determined by flow cytometry.Results Older age,larger ratio of diabetes mellitus,longer time from symptom onset to PCI,higher platelet count and levels of LDL-C,D-dimer,P-selectin,GP Ⅱ b/Ⅲ a,PNA,PM A,PLyA and plasma Panx-1 were observed in the no-reflow group than the normal and slow reflow groups(P＜0.05).The plasma Panx-1 level in STEMI patients was positively correlated with P-selectin,GP Ⅱ b/Ⅲ a,PNA,PM A and PLyA(P＜0.05,P＜0.01).LDL-C ≥3.20 mmol/L and plasma Panx-1＞0.88 μg/mL were independent risk factors for no-reflow after PCI in STEMI pa-tients(OR=2.198,95％CI:1.252-3.858,P=0.006;OR=16.849,95％CI:4.481-63.357,P=0.000).The AUC value of Panx-1 was 0.826(95％CI:0.744-0.907,P＜0.01)in predicting no re-flux in STEMI patients after PCI.Conclusion The increase of plasma Panx-1 level is closely asso-ciated with the occurrence of no reflow in STEMI patients after PCI,and the protein can be used as a predictive biomarker for the phenomenon.
