Different techniques of peritoneal closure were evaluated on their effect on the development of postoperative adhesions. Sixty rats were divided into 3 groups of 20 and each group was assigned to one technique. The peritoneum was closed in the 2 groups using different techniques; conventional or edge to edge in the first group and everted edges in the second. In the third group, the peritoneum was not closed. This study showed that there was a significant reduction in the development of postoperative adhesions with one closure of the peritoneum. Suturing of the edges of the peritoneum increased the incidence as well as the severity of postoperative adhesions.

Objective To evaluate the role of CT and MR/in the diagnosis of posterior reversible encephalopathy syndrome(PRES).Methods Eight women with PRES(6 pregnant women,1 case after chemotherapy,and 1 patient with hypertension)were enrolled in our study.All of them had MR imaging (T_1WI,T_2WI,FLAIR,DWI),and five cases underwent post-contrast T_1WI and three dimensional contrast enhanced MR angiography(3D CEMRA).Two cases also had CT scan.Results MRV in all 8 patients showed no evidence of stenosis,dilation,or thrombosis in cranial veins and sinuses.MRI demonstrated multiple lesions located in bilateral parieto-occipital lobes(8 cases),bilateral basal ganglia(2 cases),and bilateral frontal lobes(4 cases).The lesions were prominent within white matter,some of them involved gray matter(3 cases).Lesions appeared as hyperintense signals on FLAIR and T_2-weighted images, isointense or mildly hypointense signals on T_1-weighted images,normal or decreased intensity on DWI,and isointensity or hyperintensity on apparent diffusion coefficient(ADC)maps.Post-contrast T_1WI showed mild reversible enhancement and 3D CEMFdisplayed numerous reversible“grape-like”enhancements in terminal arterial branches along the middle cerebral artery(MCA),anterior cerebral artery(ACA)and posterior cerebral artery(PCA).Follow-up scan showed decreased abnormal signals.Conclusion Lesions of PRES are usually located in parieto-occipital lobes,especially in white matter,but they can also be seen in frontal lobes and basal ganglia bilaterally.Post-contrast T_1WI and 3D enhanced MRA can provide useful information in the manifestation of reversible enhancement.MRI has advantages to display lesion in PRES,

BACKGROUND/AIMS: Patients with irritable bowel syndrome (IBS) are characterized by abnormal central processing with altered brain activation in response to visceral nociceptive signals. The effect of electroacupuncture (EA) on IBS patients is unclear. The study is set to study the effect of EA on brain activation during noxious rectal distension in IBS patients using a randomized sham-controlled model. METHODS: Thirty IBS-diarrhea patients were randomized to true electroacupuncture or sham acupuncture. Functional MRI was performed to evaluate cerebral activation at the following time points: (1) baseline when there was rectal distension only, (2) rectal distension during application of EA, (3) rectal distension after cessation of EA and (4) EA alone with no rectal distension. Group comparison was made under each condition using SPM5 program. RESULTS: Rectal distension induced significant activation of the anterior cingulated cortex, prefrontal cortex, thalamus, temporal regions and cerebellum at baseline. During and immediately after EA, increased cerebral activation from baseline was observed in the anterior cingulated cortex, bilateral prefrontal cortex, thalamus, temporal regions and right insula in both groups. However, true electroacupuncture led to significantly higher activation at right insula, as well as pulvinar and medial nucleus of the thalamus when compared to sham acupuncture. CONCLUSIONS: We postulate that acupuncture might have the potential effect of pain modulation in IBS by 2 actions: (1) modulation of serotonin pathway at insula and (2) modulation of mood and affection in higher cortical center via ascending pathway at the pulvinar and medial nucleus of the thalamus.

OBJECTIVE: To investigate the efficacy and safety of polysaccharide nucleic acid-fraction (BCG-PSN) in the treatment of vasomotor rhinitis. METHOD: Sixty patients were randomly divided into BCG-PSN group (n = 30) and control group (n = 30). The patients in BCG-PSN group were administered with BCG-PSN 1.0 mg twice a week for two months, and intranasal azelastine was used if needed. The patients in control group were administered with intranasal azelastine solely twice a day, which could be decreased with the symptom relief. Follow-up was 6 months. Symptom and medication scores were recorded. Side effects were registered. RESULT: The symptom and medication scores of BCG-PSN group were significantly lower than that of control group (P < 0.01) after BCG-PSN treatment. There was no significant difference in symptom score between the two groups at 6 months after BCG-PSN treatment (P > 0.05), while the medication score of BCG-PSN group was still much lower than that of control group (P < 0.01). No serious adverse events were reported in BCG-PSN group except for local pain on the injection place in one patient. CONCLUSION BCG-PSN is effective and safe in the treatment of vasomotor rhinitis.

OBJECTIVETo determine the effectiveness of an instant haw beverage in regulating lipid disturbance, enhancing antioxidant enzyme activity and immune function.

METHODSData was collected from 60 hyperlipidemic subjects. In this crossover design, each subject randomly received either the instant haw beverage (100 ml corresponding to 3 g of haw powder or 30 g of fresh haw fruit plus the carrier-guar gum plus some starch) or placebo (guar gum 1.5 g plus some starch as the carrier of the beverage) twice daily. Each supplementation lasted 31 days with a 28-day washout period between treatments.

RESULTSThe instant haw beverage significantly reduced total serum cholesterol (9.6%), triglyceride (12.1%), LDLC (18%) while significantly increased SOD activities (7.5%). The placebo was shown to have positive results in some of the lipid profiles, though the effects of the instant haw beverage demonstrated greater significance. Serum triglyceride levels were significantly decreased and SOD activity significantly increased only as subjects were supplemented with the instant haw beverage while no significant changes were seen with placebo.

CONCLUSIONSupplementation with the instant haw beverage positively affects blood lipid profile, antioxidant status and immune function in individuals with hyperlipidemia.

Objective: The variety and efficacy of biomarkers available that may be used objectively to diagnose major depressive disorder (MDD) in adults are unclear. This systematic review aims to identify and evaluate the variety of objective markers used to diagnose MDD in adults. Methods: The search strategy was applied via PubMed and PsycINFO over the past 10 years (2013–2023) to capture the latest available evidence supporting the use of biomarkers to diagnose MDD. Data was reported through narrative synthesis. Results: Forty-two studies were included in the review. Findings were synthesised based on the following measures: blood, neuroimagingeurophysiology, urine, dermatological, auditory, vocal, cerebrospinal fluid and combinatory—and evaluated based on its sensitivity/specificity and area under the curve values. The best predictors of blood (MYT1 gene), neuroimagingeurophysiological (5-HT1A auto-receptor binding in the dorsal and median raphe), urinary (combined albumin, AMBP, HSPB, APOA1), cerebrospinal fluid-based (neuron specific enolase, microRNA) biomarkers were found to be closely linked to the pathophysiology of MDD. Conclusion A large variety of biomarkers were available to diagnose MDD, with the best performing biomarkers intrinsically related to the pathophysiology of MDD. Potential for future research lies in investigating the joint sensitivity of the best performing biomarkers identified via machine learning methods and establishing the causal effect between these biomarkers and MDD.
