OBJECTIVETo study Chinese syndrome typing of acute hepatic failure (AHF) mice model by screening effective formulae.

METHODSLipoplysaccharides (LPS)/D-galactosamine (D-GaIN) was intraperitoneally injected to mice to establish the AHF mice model. Yinchenhao Decoction, Huanglian Jiedu Decoction, Buzhong Yiqi Decoction, and Xijiao Dihuang Decoction were administered to model mice respectively by gastrogavage. The behavior and the survival rate were monitored. The liver function and pathological changes of liver tissues were detected.

RESULTSIn all the tested classic recipes, the survival rate was elevated from 10% to 60% by administration of Xijiao Dihuang Decoction. Five h after modeling, the serum alanine aminotransferase (ALT) level was (183.95 +/- 52.00) U/L, and aspartate aminotransferase (AST) (235.70 +/- 34.03) U/L in Xijiao Di-huang Decoction Group, lower than those of the model control group, but with insignificant difference (ALT: 213.32 +/- 71.93 U/L; AST: 299.48 +/- 70.56 U/L, both P > 0.05). Xijiao Dihuang Decoction could obviously alleviate the liver injury.

CONCLUSIONSXijiao Dihuang Decoction was an effective formula for LPS/D-GaIN induced AHF model. According to syndrome typing through formula effect, heat toxin and blood stasis syndrome dominated in the LPS/D-GalN induced AHF mice model.

Objective To determine the correlation of cardiovascular MRI with cardiac biomarkers and electrocardiography(ECG)in acute myocardial infarction(MI).Methods Nineteen patients with first acute MI were selected to undergo MRI on a 1.5 T system within 3-7 days after the onset of symptoms.A first-pass perfusion scan was performed with the administration of Gd-DTPA at a speed after cine MRI for global left ventricle(LV)funotions.Delay-enhanced MRI was performed by using an ECG-gated inversionrecovery fast-gradient echo-pulse sequence 5 to 10 minutes later with second bolus injection at a s peed.Infarct mass(IM),percentage size of infarction(PSI)and LV functions were compared with peak troponin T (peak TnT)and peak ereatine kinase-MB fraction (peak CK-MB).The 12-lead ECG was analysed for STelevation on admission.Pearson and Spearman correlation test and independent-Sample t test wel-e used for statistics.Results The IM (median 6.3 g) was correlated with peak TnT(median 0.8μg/L,r=0.487,P=0.0340)and left ventricle end-systolic volume index(LVESVI)(median 23.4 ml/m2,r=0.480,P=0.038).IM showed a negative correlation with left ventricle ejection fraction(LVEF)(54.1±15.4)/(r=-0.563.P:0.012).The PSI(median 6.0/)was correlated with peak TnT(r=0.583,P=0.009),peak CK.Mn(median 43.0 U/L,r=0.470,P=0.042)and LVSV[(57.6 ±15.0)ml,r=-0.482,P=0.036],peak TnT was also correlated with LVSV(r=-0.524,P=0.021).There were more involved segments(IS)(t=2.972,P=0.009),higher peak TnT(t=2.245,P=0.041)and peak CK-MB(t=2.508,P=0.024)in ST-elevation MI(STEMI)than in non ST-elevation MI(NSTEMI).Conclusions IM directly influences LV functions in acute MI.Peak TnT was a better biomarker reflecting PSI and LV functions.There were more involved segments in STEMI than in NSTEMI.

Humanin(HN,its analogue [Gly14]-Humanin,HNG)was originally identified as an endogenous peptide that protects neuronal cells from apoptosis induced by various types of Alzheimer's disease-related insults.But the relative low content of this peptide in its natural sources limits its further characterization.An expression vector pET32a/HNG was corstructed and transformed it into E.coli BL21 trxB(DE3).HNG was expressed as a fusion protein in the soluble fraction and was purified by nickel affinity chromatography.Subsequently,the purified fusion protein was cleaved by enterokinase and was further purified by reverse-phase HPLC.A 23 mg recombinant HNG(rHNG)from 1 L bacterial culture was purified.The molecular weight of rHNG determined by ESI-MS was 2876.5 Da which was the expected size for correctly processed peptide.The N-terminal amino acid sequence of rHNG determined by Edman degradation method is identical to the theoretical sequence.Neuroprotective bioassay studies of rHNG exhibited its potential neuroprotective effect comparable to that of the natural HNG peptide.

Objective To evaluate the diagnostic value of conventional and dynamic contrast- enhanced MRI in lymphoma of the orbit.Methods Thirteen cases of lymphoma of the orbit,including B-C (10 cases),T-C (1 case),T-NK-C (1 case)lymphoma,and multiple myeloma (1 case),were studied using conventional MR and dynamic contrast-enhanced MR imaging with 3D fast spoiled gradient echo sequence.Calculated values included time to peak (Tpeak),washout ratio (WR),slope and enhancement ratio (ER),and time-intensity curves (TICs),and Tpeak,WR,slope and ER were calculated preoperatively.Results Eleven of the 13 lymphomas of the orbit was seen in the anterior portion of the orbit including eyelid and lacrimal gland.On conventional MRI,10 cases showed iso-intensity on T_1WI and T_2WI and all 13 cases showed moderate enhancement after contrast administration.TIC of all 13 cases showed rapid enhancing and wash-out,Tpeak was (58.7?8.5)s,and WR was (30.9?9.4)%.The accurate diagnosis with only conventional MRI was achieved in 6 out of 13 cases,while the accurate diagnosis was achieved in all 13 cases by using combined conventional MRI and dynamic enhanment MRI.Conclusion onventional MRI combined with dynamic contrast-enhanced MRI is useful for the diagnosis of lymphoma of the orbit.

Objective To report the clinical effect of free transplanting for soft tissue defects pedieled with high site cutaneous branches of the transverse branch of lateral cirumflex femoral artery.Methods Cu- taneous branches of the descending branch of lateral circumflex femoral artery were found small or abscent in 7 patients.The anterolateral femoral skin flap was pedicled with high site cutaneous branches of the transverse branch to repair the soft tissue defects of the arm,hand,leg and foot,rather than with the descending ones. The size of the flap ranged from 15 cm?6 cm to 28 cm?13 cm,with part muscle valve,iliotibal tract and lat- eral femoral cutaneous nerve.The fractures were performed with internal or external fixation.Results All of the anterolateral femoral skin flap survived well postoperatively in the 7 cases and had good appearance and sensation at one stage.The function of the repaired extremities recovered well.Conclusion The anterolat- eral femoral skin flap pedicled with high site cutaneous branches of the transuvrse branch of lateral circumflex femoral artery has many advantages of good blood supply and large size.The flap was secluding,and can be taken with some muscle and lateral femoral cutaneous nerve.When cutaneous branches of the descending branch of lateral circumflex femoral artery is small or abscent,the anterolateral femoral skin flap with high site cutaneous branches of the transverse branch of lateral circumflex femoral artery is an optimal alternative.

OBJECTIVETo observe the clinical efficacy difference between segmentation scraping and conventional acupuncture for cervical spondylosis (CS) so as to provide effective treatment method.

METHODSEighty-five cases of cervical type of CS were randomly divided into a scraping group (44 cases) and an acupuncture group (41 cases). The segmentation scraping therapy was used in the scraping group. The scraping group was treated with focusing on scraping the head and joint part of neck and occiput in the upper cervical spine injury, and focusing on scraping the lower section of cervical and shoulder in the lower cervical spine injury, once every seven days, totally for 3 times. In the acupuncture group, Fengchi (GB 20),Wangu (TE 5), Tianzhu (BL 10),Neck-Jiaji (EX-B 2), etc. were selected,once daily,for 15 days. The visual analogue scale (VAS) was used to evaluate the immediate analgesic effect after the first treatment and the clinical efficacy was observed after the end of treatment.

RESULTSAfter the first treatment, the score of VAS was decreased significantly in the scaping group (P < 0.01), but there was no significant difference in the acupuncture group compared with those before treatment (P > 0.05); the score of VAS in the scaping group after the first treatment was lower than that in the acupuncture group (3.66 +/- 0.74 vs 5.43 +/- 0.35, P < 0.01). Compared with before treatment, the scores of VAS were decreased significantly after treatment in two groups (both P < 0.01), but without significant difference between two groups (P > 0.05); the effective rate was 95.5% (42/44) in the scaping group and 87.8% (36/41) in the acupuncture group, the curative effects were similar (P > 0.05).

CONCLUSIONBoth of scraping and acupuncture therapies have good analgesic effect for cervical spondylosis, and overall effects are similar, but the immediate analgesic effect of scraping thrapy is better than that of conventional acupuncture.
