Objective To investigate the changes in trafficking of GluRl-containing AMPA (GluR1-AMPA) receptor and GluR2-AMPA receptor from cytoplasm to cell membrane in the spinal cord dorsal horn in a rat model of incisional pain.Methods Thirty-two adult male SD rats aged 6-8 weeks weighing 280-300 g were randomly divided into 2 groups:control group (group C,n =8) and incisional pain group (group Ⅰ,n =24).An 1 cm long incision was made in the plautar surface of right hindpaw according to Brennan et al.in group Ⅰ.Cumulative pain score (CPS) and paw-withdrawal threshold to yon Frey stimuli (PWT) were measured at 3 h and day 1 and 3 afar incision ( T1,2,3 ).The animals were sacrificed after pain behavior assessment.Their lumbar segments of the spinal cord (L3-6) were removed.The expression of GluR1 and GluR2 in cell membrane and cytoplasm in spinal cord dorsal horn was determined by Western blot analysis.The co-expression of Stargazing with GluR1 and GluR2 in the spinal cord dorsal horn was examined by co-immuno-precipitation.Results The CPS was increased and PWT decreased; the GluR1 expression in cytoplasm was decreased while the expression of GluR1 in cell membrane and the co-expression of Stargazing with GluR1 were up-regulated in group Ⅰ as compared with group C.There was no significant change in the expression of GluR2 in cytoplasm and cell membrane and the co-expression of Stargazing with GluR2 in group Ⅰ as compared with group C.Conclusion GluR1-AMPA receptor transfers from cytoplasm to cell membrane but GluR2-AMPA receptor does not in rats with incisional pain.

Objective To evaluate the effects of anisodamine on apoptosis in cardiomyocytes and inflammatory response in overtrained rats. Methods Twenty-four male Wistar rats, weighing 200-220 g, were randomly divided into 3 groups ( n = 8 each) : control group (group C) , overtraining group (group O) , anisodamine group (group A) . The model of overtraining-induced acute heart injury was established by exhausting swimming. Anisodamine 10 mg/kg was given intraperitoneally 20 min before overtraining in group A. Blood samples were taken at 6 h after overtraining for measurement of serum CK-MB activity. The rats were then sacrificed and myocardial tissues taken for determination of TNF-α content and NF-κB activity (by immunohistochemistry) . The apoptosis rate was detected by flow cytometry. Results The CK-MB activity, apoptosis rate, TNF-α content and NF-κB activity were significantly higher at 6 h after overtraining in groups O and A than in group C, while lower at 6 h after overtraining in group A than in group O ( P < 0.05) . Conclusion Anisodamine can inhibit apoptosis in cardiomyocytes by reducing inflammatory response in overtrained rats.

Objective To retrospectively analyzed the current application of warfarin in hospitalized patients with non-valvular atrial fibrillationand ( NVAF), explore the key role of clinical pharmacists in warfarin medication. Methods A retrospective survey of anticoagulant therapy for 179 hospitalized patients with non-valvular atrial fibrillation in Renming Hospotal of Wuhan University from January to December 2013 was retrived,including the usage of warfarin for NVAF and new-onset atrial fibrillation,dosage,international normalized ratio(INR),hemorrhage event and so on.The simple factor like the age,complicated chronic diseases and previous cerebrovascular events on the use of warfarin was explored. Results The total response rate to anticoagulants was 85.6% for patients with high risk of stroke(27.3% with warfarin and 58.3% with antiplatelet therapy),who are recommended to use warfarin,patient were treated with anti-thrombotic therapy.The total of 19.1% of the patients with new-onset atrial fibrillation used warfarin as therapy.The whole monitoring rate of INR was 89.8%,and the good control rate was 11.9%. Univariate analysis showed that some high risk factors such as age and high blood pressure affected the usage of warfarin. Conclusion The anti-thrombotic therapy for NVAF patients in the hospital is good,but usage of warfarin for those with new-onset atrial fibrillation is low,which couldn't reach the INR standard. More attention should be taken by the clinic pharmacists in effective managing the use of anticoagulant to build a safe,economic and effective medication system for warfarin application.

OBJECTIVETo explore the possible target and molecular mechanism of Radix Paeoniae 801 (RP801), an effective ingredient extracted from Radix Paeoniae, the Chinese herbal medicine for activating blood circulation to remove blood stasis, using experimental in vitro method by directly detecting the interaction between RP801 and endothelin-1 (ET-1).

METHODSPiezoelectric quartz crystal biosensor, namely, the quartz crystal microbalance (QCM) was used to detect the specific combining between RP801 and ET-1 by binding avidin to the pre-activated Au surface of electrode of QCM, followed by immobilizing biotinylated ET-1 to it, and adding RP801, then the binding curve was recorded. PBS washing was applied at the end of every steps of combining reaction for dissociate the non-specific absorption.

RESULTSSpecific combining of RP801 and ET-1 was found.

CONCLUSIONET-1 could possibly be one of the acting targets of RP801 in the body, that is, RP801 could combine with ET-1 to impede the binding of ET-1 with its receptor, so as to counteract the action of ET-1, dilate blood vessels and inhibit platelet aggregation.

Leukemia inhibitory factor (LIF) plays important roles in varieties of biological processes. This factor is highly conserved in mammalian animals and only one heterozygous LIF mutation was reported to cause the infertility of women. A LIF mutation was generated and the evidences were provided that the mutation of mature LIF at the 29th amino acid totally abolished its functions, including stimulation of STAT activation assayed by Luciferase reporter gene expression and EMSA experiments. In addition, the mutated LIF failed to inhibit the proliferation of M1 cells. The data indicated that the mutation of LIF did not have a dominant negative effect but lost the biological functions, suggesting that the 29th amino acid is critical for maintaining the activities of LIF.

Objective To observe changes of the nitrogen balance in premature infants with extrauterine growth restriction (EUGR) during hospitalization.Methods We selected a total of 64 very preterm (VP) infants admitted to Neonatal Medical Center of Huai'an Maternity and Child Healthcare Hospital affiliated to School of Medicine, Yangzhou University within 24 hours after birth and with gestational age ＜ 32 weeks from May to October 2014, and divided them into EUGR group (n =18) and non-EUGR group (n =46) according to the diagnostic criteria of EUGR.All of the infants' urea nitrogen levels were detected by Kjeldahl method on the 1st, 7th, 14th, and 28th days after birth, and nitrogen balance scores were calculated and compared between the EUGR and non-EUGR groups.Results Nitrogen balance scores of the two groups were all negative on the 1 st, 7th, 14th, and 28th days after birth, with a tendency rising with days.A significant difference was showed in the intra-group comparison in EUGR group on the 1st, 7th, 14th, and 28th days after birth (-492.66 ±204.39,-290.79 ± 173.78,-205.96 ± 180.59, and-145.14 ± 140.15, respectively, F =53.086, P =0.000), so was in the non-EUGR group (-383.41 ± 130.57,-278.91 ±225.80,-182.00 ± 144.70, and-61.08 ±49.71, respectively, F =41.745, P =0.000).At each observation time point after death, the nitrogen balance score in the EUGR group was lower than in the non-EUGR group, and the differences on the 1st and 28th days were statistically significant (both P ＜ 0.05);while those on the other time points were not statistically significant (both P ＞ 0.05).Conclusion The VP infants are at a negative nitrogen balance during hospitalization, among whom the EUGR premature infants may be more serious.
