Acute coronary syndrome(ACS) belongs to “thoracic obstruction” and “heartache” in traditional Chinese medicine.Although many ancient physicians has discussed this disease,while due to the impact of “Yang Wei Yin Xian” in Zhang Zhong-jing's theory,the disease caused little attention by far.In the clinical practice,the author found that most ACS patients belong to heat syndrome.Based on TCM constitution theory,the author put forward the ACS was mainly caused by heat accumulation and blood stasis due to the changes of living environment,lifestyle,and diet,etc.According to traditional Chinese medicine theory,emotional disorder,spicy and hot food can burn body fluid,leading to blood stasis.Long term of blood stasis turns to heat,which further consumes heart blood and aggravates blood stasis.Therefore heat accumulation and blood stasis should be paid attention in the treatment of ACS.

Objective:To evaluate the security, efficacy and side effects of E_2 transdermal patch (Fem-7) in the treatment of menopausal syndrome. Methods:A total of 60 cases with menopausal syndrome (blood serum FSH >30 U/L,E_2 <109.8 pmol/L) were randomly divided into treatment group ( Fem-7 group) and control group (estrodiol valerate (E_2V) group) for 12 weeks treatment. Fem-7 group changed patch every 7 days and took the 2 mg medroxyprogesterone (MPA) every day. While the E_2V group took the 2 mg MPA and 1.5 mg E_2 V every day. Serum E_2, FSH, lipoprotein and coagulation function were evaluated at baseline and at the 12th week of the treatment. In addition, menopausal symptoms and some other index of security and side effects were also observed. Results:Kupperman indix in both groups was decreased and the mean value of E_2 was increased obviously. Hepatic function, renal function, coagulation function and blood glucose were no obvious change. Lipoproteina was descended markedly in Fem-7 group. Other index of security in both groups was no obvious change. Conclusions:Fem-7 patch is secure and valid for relieving symptom of menopause, especially for the women who is not sutable for oral medication.

Recently,the new term lamellar hole-associated epiretinal proliferation was introduced to describe a specific epiretinal proliferation.Different from conventional epimacular retinal membrane,lamellar hole-associated epiretinal proliferation (LHEP) can be found around the edge of lamellar macular holes and part of full thickness macular holes.It is defined as a thick homogenous layer of yellowish material without any contractive properties on the epiretinal surface with medium reflectivity on optical coherence tomography images.Immunocytochemical analysis showed the presence of glial cells,fibroblasts,hyalocytes and collagen type Ⅱ.Electron microscopy revealed fibroblasts and hyalocytes as predominant cell types,densely packed in cell agglomerations.LHEP is a secondary event in lamellar macular hole formation and may represent a repair process after large and deep retinal defect.Further studies on its clinical features and clinical significance are still required.

Objective To evaluate the effects of different dosage of aspirin and clopidogrel on the platelet inhibition rate by thromboelastography (TEG)before stent-assisted embolization of aneurysms. Methods The clinical data of 57 patients with unruptured aneurysms treated by stent-assisted coil embolization in General Hospital of Nanjing Military Command were analyzed retrospectively. The patients were divided into a low dose group (aspirin 100 mg + clopidogrel 75 mg,26 cases)and a high dose group (aspirin 300 mg +clopidogrel 75 mg,31 cases). All the patients were treated with aspirin and clopidogrel before surgery. The blood samples were collected on day 3 after oral administration with anti-platelet aggregation drugs. TEG was used to detect the arachidonic acid (AA )-induced inhibition rate of platelet aggregation and adenosine diphosphate (ADP)-induced inhibition rate of platelet aggregation. The platelet inhibition and drug resistance,as well as ischemic complications in the perioperative period between the two groups were compared. Results (1 )The platelet inhibition rates:there was no significant difference in the inhibition rates of platelet aggregation of AA and ADP between low dose group and high dose group at day 3 after oral antiplatelet drugs [AA inhibition rate:(76 ± 21)% vs. (80 ± 21)%;ADP inhibition rate:(72 ± 26)% vs. (73 ± 29 )%;all P >0. 05 ]. (2 )Drug resistance:in the low dose group,the patients of aspirin and clopidogrel resistant were 2 cases(7. 7%)and 1 case(3. 8%),and the patients in high dose group were 3 cases (9. 7%)and 4 cases(12. 9%). No statistical significant difference in the aspirin and clopidogrel resistant was detected in the two groups (all P>0. 05). (3)The ischemic complications in the perioperative period:there was 1 case (3. 8%)with ischemic complications in the low dose group,and 2 cases (6. 5%)in the high dose group. There was no significance difference in the incidence of ischemic complications between the two groups(P >0. 05). Conclusion For patients treated with stent-assisted embolization of aneurysms,no difference could be detected in the inhibitory effect of platelet aggregation between low and high dose groups of aspirin.

Guided by the antioxidant activity, the EtOAc-soluble and n-butanol-soluble fractions of the 50% methanol extract of Lonicera japonica leaves were isolated and purified by various chromatorgraphic methods, and the structures were identified by spectral analysis and comparison to the data reported in literature. As a result, nine compounds were obtained and identified as 5-O-caffeoylquinicacid (1), chlorogenicacid (2), 4-O-caffeoylquinicacid (3), luteolin-7-O-[α-L-arabinopyranosyl-(1 --> 6)] -β-D-glucopyranoside (4), luteoloside (5), 3,4-di-O-caffeoylquinic acid (6), 3,5-di-O-caffeoylquinic acid (7), 4, 5-di-O-caffeoylquinic acid (8) and luteolin (9). The antioxidant activity of the nine compounds were determined by using DPPH free radical scavenging method, and ascorbic acid was used as a positive control. Their antioxidant activities from high to low were 5 > 9 > 2 > 8 > 7 > 6 > 1 > 3 > 4. Among them, luteoloside (5) had the strongest antioxidant activity with an IC50 of 0.018 18 g x L(-1), and luteolin (IC50 0.023 6 g x L(-1)) and chlorogenicacid (IC50 0.035 17 g x L(-1)) ranks No. 2 and 3. Furthermore, the antioxidant activity of luteoloside and luteolin were stronger than that of ascorbic acid (IC50 0.027 54 g x L(-1)). These results gave a basis for the further study and utilization of L. japonica leaves.

Objective To identify and confirm a novel HLA allele.Methods A new human leukocyte antigen A allele was found during routine HLA genotyping by polymerase chain reaction-sequence specific oligonucleotide probes(PCR-SSOP) and sequencing-based typing (SBT).HLA-A locus was amplified from exon 1 through exon 8,and the nucleotide sequence of exon 2 to exon 4 for HLA-A were sequenced in both directions.Results The novel HLA-A * 31 allele is identical to A * 31 ∶ 01 ∶ 02 with an exception of one base substitution at position 245 of exon 2 where an ' A' change to ' C' resulting in codon 82 changed from GAG to GCG.Conclusion A novel HLA allele,A * 31 ∶ 22,was identified,and was named officially by the WHO Nomenclature Committee for factors of the HLA system.

ObjectiveTo investigate the feasibility of preventing tendon adhesion by using bFGF/ vitamin C composite biodegradable membrane.MethodsSixty Newzerland rabbits were divided into experimental and control groups randomly.After the animal model was established, the tendon autografts were encapsulated with the bFGF/vitamin C composite biodegradable membrane in experimental group, while no tendon autografts encapsulation in control.Three weeks after surgery, regular HE staining and AgNO3 staining were performed to observe the fibroblast nuclei and vitamin C.The quantity of collagen fibrils was measured by Luzex-F Image Analyzer.Eight weeks after surgery, the peritendinous adhesion and the maximum tensile load were analyzed.Results At 3 weeks after surgery, the numbers of vitamin C granules, fibroblast nuclei and collagen fibrils in the experimental group were significantly more than those in the control group(t = 11.78 ,P <0.001) .At 8 weeks after surgery, the peritendinous adhesion in the experimental group was significantly slighter than that in the control group(Z =3.922,P <0.005) ,and the maximum tensile load in the experimental group was significantly higher than that in the control group (t = 8.39, P < 0.001) .ConclusionbFGF/vitamin C composite biodegradable membrane can stimulate the proliferation of fibroblasts and synthesis of collagen fibrils,improve the biomechanical property of tendon autografts and prevent the tendon adhesion.
