Objective To report a case of deep mycosis caused by Rhizomucor chlamydosporus. Methods Medical history,histopathology and laboratory examination were investigated,and fungal identifi- cation by microscopy and culture as well in the patient.Results The patient,a 41-year-old male,initially presented with mild-tender and progressively aggravating masses on the right glutea,both groins,and back of the head of pancreas.Later,ulcer,necrosis,and black crusts developed at the primary lesions accompanied with nausea,vomitting and dysfunction of liver.Pathological examination revealed a chronic granuloma- tous inflammation in the dermis and subcutaneous tissue;and branching,nonseptate and broad hyphae in multinuclear giant cells,tissue spaces and blood vessel lumens,and,few PAS-positive septate hyphae as well as basophilic chlamydospores located in multinuclear giant cells.The isolate was identified as R. chlamydosporus.Conclusions The case of deep mycosis caused by R.chlamydosporus began with invasive granuloma,followed by necrotic ulcer,with condition aggravating rapidly,and the patient finally died of se- rious cachexia.

OBJECTIVETo determine whether preoperative contrast delay-enhanced cardiovascular magnetic resonance imaging (DE-CMR) could help predict long-term survival of patients with severe chronic aortic regurgitation and extremely dilated left ventricular chamber after aortic valve replacement.

METHODSTotally 37 patients enrolled between February 2008 and November 2010 with severe chronic aortic regurgitation and extremely dilated left ventricular chamber, who met the echo criteria, that was left ventricular end diastolic dimension > 70 mm or left ventricular end systolic dimension > 55 mm, and were scheduled to the surgery. The 2-dimensional echocardiographic examinations and CMR with late gadolinium-enhancement (LGE) were performed routinely preoperatively. According to the results of CMR, the patients were divided into 2 groups: the LGE positive(+) group and LGE negative(-) group. The association of LGE with event free survival, postoperative cardiac function and postoperative hospital stay time was investigated. Fifteen patients had significant LGE signals in CMR films, while the other twenty-two were silent. All of them received the operative procedures, including aortic valve replacement in 28 cases, Bentall procedure in 3 cases, aortic valve replacement and ascending aorta replacement in 6 cases, and concomitant mitral valve repair in 11 cases.

RESULTSOver a follow-up of 33.6 months, 1-year, 2-year and 3-year event free survival rates in LGE(-) group were 94.7%, 88.4%, and 72.6%, respectively, compared to 80.0%, 48.9%, and 32.6%, respectively in LGE(+) group (χ(2) = 7.244, P = 0.007). The postoperative hospital stay time of LGE(-) group was (9 ± 2) days, which of LGE(+) group was (10 ± 3) days (t = 1.175, P = 0.248).

CONCLUSIONSLGE positive signal in CMR films is a potential predictor of persistent cardiac failure after aortic valve replacement for patients with severe chronic aortic regurgitation and extremely dilated left ventricular chamber. It has intimate relationship with malignant arrhythmia and sudden death, which makes it a valuable technique in preoperative evaluation and risk stratification.

XI Hong, a famous acupuncturist in the Southern Song Dynasty, has an important influence and status in history of Chinese acupuncture and moxibustion. After he moved to Linchuan, Jiangxi province, his descendants passed acupuncture from generation to generation. According to records, it was passed to 12 generations. After the tenth generation, it was also passed to apprentices besides descendants, such as accomplished acupuncturists CHEN Hong-gang, LIU Jin and others, forming XI Hong acupuncture school of thought. The poem of acupuncture and moxibustion XI Hong Fu is the representative work about XI Hong academic thought, which was additionally compiled or written by XI Hong's apprentices according to XI Hong academic thought. The poems are of characteristics in acupuncture application and association of acupoints. The academic thought and therapeutic methods of acupuncture in the poems still are widely used in modern clinical acupuncture practice.

OBJECTIVETo observe the effects of warming yang method, nourishing yin method, activating blood method, and the combined treatment method on the ventricular remodeling (VR) and the heart function of heart failure (HF) rats of Shen-yang deficiency syndrome (SYDS).

METHODSThe Sprague-Dawley (SD) HF rat model of SYDS was established by continuously intravenous dripping adriamycin after economizing bilateral thyroid tissues. Rats were then randomly divided into the model group (administered with normal saline at the daily dose of 6 mL/kg by gastrogavage), the warming yang group (administered with Wenyang Jianxinling Extractum at the daily dose of 6 mL/kg by gastrogavage), the activating blood group (administered with Ligusticum Wallichii and Salvia Miltiorrhiza Extractum at the daily dose of 6 mL/kg by gastrogavage), the nourishing yin group (administered with Radix Ophiopogonis and Rhizoma Anemarrhenae Extractum at the daily dose of 6 mL/kg by gastrogavage), and the combined treatment group (administered with Yin-Yang Supplementing Extractum at the daily dose of 6 mL/kg by gastrogavage), 10 in each group. Another 10 SD rats were taken as the normal control group. They ate food and drank water freely. All rats were intervened for four successive weeks. The left ventricular systolic pressure (LVSP), left ventricular end diastolic pressure (LVEDP), maximal rate of left ventricular pressure of development ( +dp/dtmax), and maximal rate of left ventricular pressure of decline (-dp/dtmax) were observed. The systolic blood pressure (SBP) and the diastolic blood pressure (DBP) were determined. The mean arterial pressure (MAP) was calculated. The heart rate (HR) was recorded. Then all rats were killed and their hearts were taken out to weigh the heart mass (HM), the left ventricular mass (LVM), the right ventricular mass (RVM). The heart mass index (HMI) and the left ventricular mass index (LVMI) were calculated. The mRNA expression of matrix metalloproteinase-9 (MMP-9) and tissue inhibitor of metalloproteinase-1 (TIMP1) in the myocardium were detected using RT-PCR. The serum levels of N-terminal pro-brain natriuretic peptide (NT-proBNP), MMP-9, and TIMP-1 were assayed by double antibody sandwich ELISA.

RESULTSCompared with the normal control group, HR, LVEDP, HM, LVM, HMI, RVM, LVMI, NT-proBNP, MMP-9, and MMP-9 mRNA significantly increased, but SBP, DBP, MAP, LVSP, +/- dp/dtmax, TIMP-1, and TIMP-1 mRNA significantly decreased in the model group with statistical difference (P<0.05). Compared with the model group, SBP and DBP, +/-dp/dtmax increased,while LVEDP, NT-proBNP, and MMP-9 decreased in the warming yang group. HR, LVEDP, HM, LVM, HMI, RVM, LVMI, MMP-9 mRNA, NT-proBNP, and MMP-9 significantly decreased, while TIMP-1 mRNA increased in the activating blood group. HR, LVEDP, +/- dp/dtmax, LVMI, NT-proBNP, and MMP-9 decreased, while TIMP-1 increased in the combined treatment group, showing statistical difference (P<0.05). Compared with the warming yang group, SBP and +dp/dtmax decreased in the nourishing yin group; HR and MMP-9 mRNA decreased in the activating blood group, HR decreased in the combined treatment group, all showing statistical difference (P<0.05). There was no statistical difference in the rest indices (P>0.05).

CONCLUSIONActivating blood method and combined treatment method could regulate the expressions of MMP-9 and TIMP1 mRNA of HF rats of SYDS, effectively ameliorate the VR, and improve the HF.

OBJECTIVETo investigate the antiviral effect of targeted antisense oligodeoxynucleotides (asODN) in HBV transgenic mice.

METHODSasODN phosphorothioated (5'-CATGCCCCAAAGCCAC-3') targeted to HBV pre-C/C region was synthesized. Gal15-PLL was used as drugs carrier which targeted asODN to mice liver. Twelve mice with positive serum HBsAg, HBV-DNA were divided into the Gal15-PLL-asODN-treated group or the control group randomly. In Gal15-PLL- asODN-treated group, each mouse was injected i.v. asODN 15mug/g weighty/day via tail vein for 12 days successively; while in the control group, each mouse received the same volume normal saline by the same way.

RESULTSIn the Gal15-PLL- asODN-treated group, serum HBsAg decreased at the 6th day (P<0.05), and decreased significantly at the 12th day vs pretreatment (P<0.01). The serum HBV DNA of 4/6 mice became negative. Immunohistochemistry test showed lowered HBsAg, HBcAg content in the liver. In contrast, the control group showed no apparent changes.

CONCLUSIONSGal15-PLL-asODN targeted to pre-C/C region could inhibit HBV replication and gene expression.

OBJECTIVETo investigate the effect and mechanism of Compound Salvia injection (CSI) on nitrate ester tolerance.

METHODSEighty-four patients with coronary heart disease (CHD) were randomly divided into three groups, Group A treated with isosorbide dinitrate (ISD, 15 mg, 4 times per day) alone, Group B with ISD plus CSI and Group C with ISD plus vitamin C. The therapeutic course for all groups was 10 days. The tolerance to nitrate ester and blood pressure were monitored. Before and after treatment, the color Doppler ultrasonic apparatus was used to detect the baseline value of humeral arterial internal diameters (D0), the humeral arterial dilatory response under compression [D1, that is, the flow-mediated vasodilation (FMD)] and the vasodilatory response after sucking of nitroglycerin (D2). And the blood levels of endothelin-1 (ET-1), endothelial nitric oxide synthase (eNOS) mRNA expression were determined. The endothelial-dependent vasodilation (EDD) was expressed by (D1 - D0)/D0 x 100%, and the endothelial-independent vasodilation (EID) was expressed by (D2 - D0)/D0 x 100%.

RESULTS(1) The occurrence rate of nitrate tolerance in Group B and C (28.57% and 35.7%) was lower than that in Group A (64.29%), but insignificant difference was found between the former two. (2) After treatment, blood pressure increased in Group A to the level of pre-treatment, that in Group C also increased but still lower than that of pre-treatment, while insignificant increase was observed in Group B, comparison between Group B and C showed significant difference (P < 0.05). (3) After treatment, EID lowered in Group A, EDD increased in Group B and C (P < 0.05), EDD and EID in Group B and C were higher than those in Group A (P < 0.05), and EDD was higher in Group B than in Group C (P < 0.05). (4) After treatment, ET-1 mRNA expression lowered in Group B, eNOS mRNA expression increased in Group B and C, with significant difference as compared with those before treatment and those in Group A (P < 0.05), and eNOS mRNA expression in Group C was lower than that in Group B (P < 0.05).

CONCLUSIONCSI could partially prevent the occurrence of tolerance to nitrate ester, with the effect better than vitamin C, the mechanism might be related with its regulation on eNOS, ET-1 mRNA expression and protection on vascular endothelial function.
