Objective To study the influence of nursing intervention on metabolic syndrome of schizophrenia patients treated with Olanzapine.Methods 100 acute-episode schizophrenia patients treated with Olanzapine alone were randomized into the intervention group and the control group,each group with 50 cases.The control group received the routine psychiatric nursing,and the intervention group added nursing intervention to prevent metabolic syndrome.The changes of BMI,fasting blood-glucose,triglyceride,cholesterol,high-density lipoprotein of both groups were compared on the day upon admission and on the 4th,8th,12th and 48th weeks after hospitalization respectively.Results On the 4th week BMI and fasting blood-glucose,triglyceride,cholesterol of the intervention group were significantly lower than those of the control group,but high-density lipoprotein was higher than the control group.Conclusions Strengthening nursing intervention measures can effectively control metabolic syndrome caused by Olanzapine treatment,which can improve the medication compliance of patients and prevent schizophrenia recurrence.

Angiopoietin-1 (Ang-1) is a newly-found endothelium-specific proangiogenic factor and it had been proved essential roles in both vasculogenesis and angiogensis. Among them, its anti-leakage ability may have great potential applications in clinical treatment of vascular hyper-permeability in a variety of diseases such as cancer, diabetic retinopathy, rheumatoid arthritis, asthma. In this review, some research progresses focused on this aspect are discussed. [

Objective To investigate the distribution of interstitial Cajal-like cells(ICLC) in ampulla and the myoelectric activities of the sphincter of Oddi(SO) of adult guinea-pigs.Methods C-Kit immunohistochemical staining was carried out on whole-mount preparations of guinea-pigs' ampulla region.The myoelectric activities of SO were recorded by using the contact electrode on mucosa.Result C-Kit-positive ICLC were observed in both exterior and inner wall of ampulla.Some of these cells were distributed in the circular and longitudinal smooth muscle cell(SMC) layers assuming a spindle-like shape.Another sub-group of ICLC,which were located between the longitudinal and circular SMC layers,were shown to have oval or triangle cell bodies with projection of more than three long processes.These cells interlaced into a cellular network,closely resembling the interstitial cells of Cajal(ICCs),around the myenteric nervous plexus(ICC-MY) in the duodenum.At the inner side of circular SMC layer of the exterior wall,ICLC were similar to ICCs associated with the deep muscular plexus(ICC-DMP) of small intestine.In the inner wall of the ampulla,a large amount of ICLC were found in the SMC layers or bundles,running parallel with them.At the opening of the ampulla,a number of ICLC surrounded the opening to form a ring.The spontaneous rhythmic myoelectric activities could be recorded in the SO.Conclusion It is suggested that the ICLC might contribute to the regulation of the spontaneous rhythmic contraction,and it might be related to development of motility disorders of the SO.

The research was carried out to establish HPLC fingerprints of Tibetan medicinal herb "Songdi" (Saxifraga umbellulata var. pectinata), and to provide reference for identification an quality control of it. It was performed on an Amethyst-C18-P (4.6 mm x 250 mm, 5 microm) column with the mobile phase of methanol-0.4% formic acid in a linear gradient mode at a flow rate of 1.0 mL x min(-1). The column temperature was 30 degrees C, and the detection wavelength was set at 254 nm. The software for chromatographic fingerprint was applied to analyse the pattern analysis, the common peaks and similarity. Cluster analysis was done based on the common peaks data of 33 samples from different plant species and sources by SPSS software. Ten common chromatographic peaks were identified by fingerprint, showing a low similarity in constituent and variety. Flavonoids and saponins were the principal components. The number and area of peaks were affected by the collection sources and method. The high similarity are showed by the samples derived from the same area with high accuracy and high purity. The method is so simple, exclusive, stable and high repeatable that it can provide reference for identification and quality assessment of "Songdi" (S. umbellulata var. pectinata).

AIM: To clarify whether advanced glycation end products (AGEs) can influence the expression of mitochondrial fusion proteins Mfn1 and Mfn2 in cultured human aortic endothelial cells (HAECs) in vitro.METHODS:AGE-BSA was used as AGEs.Purchased primary human aortic endothelial cell line was multiplied, and transferred to dif-ferent passages for subsequent grouping.For dose-dependent experiment, HAECs were divided into 4 groups, and the con-centrations of AGE-BSA in each group were 0 mg/L (control group), 50 mg/L, 100 mg/L and 200 mg/L, respectively. For time-dependent experiment, HAECs were divided into 5 groups with the same concentration (100 mg/L) of AGE-BSA, but the intervention time was 0 h (control group), 6 h, 12 h, 24 h and 48 h, respectively.The mRNA and protein expres-sion levels of Mfn1 and Mfn2 in the HAECs were detected by real-time PCR and Western blot, respectively.RESULTS:Exposure of the HAECs to AGEs at different concentrations for 24 h all down-regulated the mRNA and protein expression levels of Mfn1 and Mfn2.Except for 6 h intervention group, 100 mg/L AGEs intervention for 12 h, 24 h and 48 h all down-regulated the mRNA and protein expression levels of Mfn1 and Mfn2 in cultured HAECs.CONCLUSION: AGEs down-regulates the expression of mitochondrial fusion proteins Mfn1 and Mfn2 in cultured HAECs, indicating that AGEs may influence mitochondrial dynamics of human aortic endothelial cells.

OBJECTIVETo observe the prevention and clinical efficacy of combination of Liuwei Dihuang Pill (LDP) and Ginkgo Leaf Tablet (GLT) for early diabetic retinopathy (DR).

METHODSUsing randomized, double-blind, double simulation, parallel controlled clinical trial, 140 type 2 diabetes mellitus (T2DM) outpatients were recruited and assigned to the treatment group and the control group, 70 in each group. All patients received basic Western medicine treatment (such as blood glucose and pressure control). Patients in the treatment group took LDP (8 pills each time, 3 times per day) and GLT (19.2 mg each time, 3 times per day), while those in the control group took LDP placebos and GLT placebos. All treatment lasted for 24 consecutive months. All subjects were followed-up every month. The general clinical data as sex, age, and metabolic data such as blood glucose, blood pressure, blood lipid, and DR prevalence rate were collected and statistically analyzed.

RESULTSThere was no significant difference in levels of blood glucose, blood pressure, or blood lipid between the two groups (P > 0.05). After treatment the DR incidence rate was significantly lower in the treatment group than in the control group [3.1% (2/64) vs 18.6% (11/59), P < 0.05)]. Meanwhile, the DR prevalence rate of the treatment group was also significantly lower than that of the control group [6.3% (4/64) vs 20.0% (13/59), P < 0.05].

CONCLUSIONCombination of LDP and GLT could effectively prevent and treat the development of DR in T2DM patients.

Objective] To explore a new method of synthesis of resveratrol oligmer induced by photosensitizers, further analyze its free radical scavenging activity and analgesic activity. [Method] Resveratrol was dispersed in pH 7.4 phosphate buffer solution, mixed with pheophorbide, then illuminated by laser at 630nm. The oligmers in the filtrate were analyzed by HPLC-MS and isolated by preparative liquid chromatography. Free radical scavenging activity was determined by DPPH and ABTS method, and the analgesic effect was measured by hot plate test and acetic acid writhing test in mice. [Result] A new peak occurred and reached stable in reactive solution after 20 min illumination. It was identified as the dimer of resveratrol with conversion of 35%. Its concentrations on inhibition of 50% DPPH and ABTS radical were respectively 230 μg·mL-1 and 273 μg·mL-1. It reached maximum pain threshold at 180 min, and the inhibition rate of writhing number was 62.6% with better effects than resveratrol. [Conclusion] Reseratrol can be polymerized to the dimer after pheophorbide excited by red light, the resveratrol and its dimer both have the ability of eliminating free radicals and analgesic effects, but the dimer has the stronger activity.
