ObjectiveTo evaluate the feasibility and the value of videodensitometric scale (VDS) in assessing myocardial microperfusion. Methods11 Beagles were embolized small coronary artery with polystyrene microbubble (100 μm). Coronary angiography was performed after the embolization and the VDS was calculated. Single photon emission computerized tomography (SPECT) was also performed after embolization and SPECT scores were also calculated. ResultsVDS after embolization was (15.2±3.8); and SPECT score was (17.6±6.4). VDS correlated negatively with SPECT scores (r=－0.85, P<0.05).ConclusionVDS keeps a closely correlation with SPECT. It can be used to assess myocardial microcirculation in clinical.

Objective To evaluate the feasibility and the value of videodensitometric scale(VDS)assessing myocardial microperfusion.Methods The small coronary arteries of 11 dogs were embolized by ejecting polystyrene microbubble(dm= 100 μm),six embolized at left anterior descending branch(LAD)and five embolized at left circumflex branch(LCX).Coronary angiography was performed before and after the embolization.The myocardial contrast echocardiography(MCE)was performed in 12th hour after embolization.VDS was calculated according to coronary angiography.MCE scales were calculated.Results Among the eleven experimental dogs,VDS before embolization was 24.4±4.9 and that after embolization was 15.2±3.8.VDS after embolization was obviously lower than before embolization(P<0.05).VDS between LAD and LCX at the same stage was no difference;MCE scores after embolization were 7.6±2.4.VDS was negatively dependent with MCES after embolization(γ=-0.78,P<0.05).Conclusion As a newly quantitative index and keeping a closely correction with MCE,VDS can be used as a quantitative index to assess myocardial microperfusion in clinic.

Objective To evaluate the feasibility and the value of video density scale (VDS) for assessing myocardial microperfusion.MethodsVDS and corrected TIMI frame counted (CTFC) were calculated and compared in 58 cases undergoing coronary catheter angiography.ResultsVDS of 58 cases was (22.5±5.8)and 95% confidence interval of normal myocardial microperfusion is(20.2,24.7).The CTFC was (21.1±4.5).It showed negative correlation between VDS and CTFC.ConclusionVDS is feasible to assess myocardial microperfusion quantificationally.The possibility of myocardial microperfusion dysfunction would be increased when VDS is lower than 20.

Objective To analysis complications and its associated risk factors of high intensity focused ultrasound (HIFU) in treatment of uterine leiomyoma for selecting rationale indicated patients and reducing complications. Methods Medical documents of 171 patients with 231 leiomyomas in total treated by HIFU were studied retrospectively. Common complications were categorized and analyzed, the relationship between risk factors and complications were studied. Results Common complications in treatment of uterine leiomyomas by HIFU were 71.9% (123/171) of abdominal pain, 17.5% (30/171) of vaginal bloody discharge, 8.2% (14/171) of sacroiliac or buttock pain, 7. 6% (13/171) of skin blister,4. 7% (8/171) of leg pain, 2. 9% (5/171) of hematuria and 1.8% (3/171) of febrile. By logistic regression analysis, the factor correlated with abdominal pain included diameter of uterine leiomyomas,sonication time and average power (P < 0. 05). The factor correlated with sacroiliac or buttock pain was uterine leiomyomas located in posteriors of uterine wall(P <0. 05); the factors correlated with vaginal bloody discharge were sonication time and type of uterine leiomyomas (submucous > intramural > subserous, P <0. 05); the factors correlated with skin blister was sonication time (P < 0. 05). There were no statistical relationship between multiple factors and leg pain, hematuria, febrile (P > 0. 05). Conclusion The modality of high-power and short-term treatment might reduce complications of HIFU ablation.

Objective: To investigate the effects of inflammatory pain on local tissue structure, inflammatory reaction and expression levels of TNF-α and MCP-1 in formaldehyde-induced inflammatory pain in mice. Methods: Sixty-four adult male mice were randomly divided into NS group (40 μL of saline injected into the wrist of right forelimb), FCOH group (50 mL/L formaldehyde of 40 μL injected into the wrist of right forelimb), L group (5 μg/mL lidocaine of 0.3 mL for brachial plexus anesthesia) and FCOH+L group. Some of the tissue samples were collected at 48 h after formaldehyde modeling to observe the infiltration of inflammatory cells by HE staining. The rest were used to assess the expression levels of TNF-α and MCP-1 by Western blot. Results: Compared with NS group, FCOH group showed peak inflammatory response at 24 h (thickness of injection sites: 1.73 mm vs. 4.02 mm, temperature: 37 ℃ vs. 38.3 ℃, P<0.05). However, FCOH+L group showed intense inflammatory responses at 48 h (thickness of injection sites: 1.68 mm vs. 5.10 mm, temperature: 37 ℃ vs. 38.5 ℃, P<0.05). Furthermore, after 48 h FCOH group had a lower degree of infiltration of inflammatory cells and higher expression levels of TNF-α and MCP-1 than those in FCOH+L group (P<0.05). Conclusion: Inflammatory pain plays a significant role in the healing process of injured issues by facilitating the local inflammation and affecting the duration. The expression levels of TNF-α and MCP-1 in local tissues decrease by interrupting the transmission of pain.

OBJECTIVETo study the mutations in exons 3, 6, 7, 11 and 12 of the phenylalanine hydroxylase gene (PAH) in Shanxi population.

METHODSThe mutations in exons 3, 6, 7, 11 and 12 and flanking sequences of PAH gene were detected by PCR-DNA sequencing, in 59 patients with phynelketonuria(PKU) and 100 healthy children from Shanxi province.

RESULTSBy sequence analysis, three single nucleotide polymorphism (SNP) Q232Q (CAA>CAG), V245V (GTG>GTA) and L385L (CTG>CTC) were detected in both the patients and healthy children, with the frequencies of nt 696, 735 and 1155 of the PAH cDNA up to 96.2%, 76.1% and 7.6% in patients respectively, and 97.0%, 77.3% and 8.3% respectively in the healthy controls. In addition, 72 different mutations accounting for 61.0% of mutant alleles were identified in the patients only. In exon 3, R111X, H64>TfsX9 and S70 del were found accounting for 5.1%, 0.8% and 0.8%; EX6-96A>G in exon 6 was found accounting for 10.2%. In exon 7, R243Q was the highest incidence accounting for 12.7%, followed by Ivs7+2 T>A(5.1%) and T278I(2.5%); the lowest incidences were G247V, R252Q, L255S, R261Q and E280K accounting for 0.8 %, respectively. In exon 11, Y356X (5.9%) and V399V (5.1%) were found; in exon 12, R413P and A434D were found accounting for 5.9% and 2.5%. In total, 9 missense mutations, 3 splice site mutations, 2 nonsense mutations and 2 deletions were included in 16 kinds of different mutations.

CONCLUSIONThe mutation characteristics and distribution in exons 3, 6, 7, 11 and 12 of the PAH gene have been identified, and it suggested that the EX6-96A>G and R243Q were the hot spots of PAH gene mutations in Shanxi PKU population.

The aim of this paper was to investigate the potential pharmacological effect of flavonoids in Sophora alopecuroides by network pharmacology. This study predicted the potential targets of 11 flavonoids of S. alopecuroides with help of reversed pharmacophore matching target recognition service platform (PharmMapper). The pathway information was acquired from DAVID and KEGG databases. Cytoscape software was used to construct the "ingredient-target-pathway" network of flavonoids active components of S. alopecuroides. The flavonoids active components of S. alopecuroides play anti-inflammatory, blood sugar regulating and other pharmacological effects by regulating 62 targets (such as INSR，KDR，MET) and intervening 44 pathways, such as B cell receptor signaling pathway, insulin signaling pathway, neurotrophin signaling pathway, and T cell receptor signaling pathway. In this study, the mechanism of "muti components-multitargets-multiple pathway" of flavonoids was studied. It reflects the multi-components, multi-targets and multiple pathway features of traditional Chinese medicine. Meanwhile, it provides a scientific basis for the elucidation the mechanism of S. alopecuroides as a medicine, and the development and utilization resources of S. alopecuroides.
