OBJECTIVETo explore the relationship of the classification of talus fracture and surgery methods with avascular necrosis.

METHODSFrom March 2009 to November 2013, 78 patients with talus fracture were treated, of them, 43 cases were followed up from 2 to 5 years. There were 27 males and 16 females, aged from 17 to 65 years old with the mean of 38.6 years. Thirty-nine cases had talar neck injury and 4 cases had talar body injury. Different treatments were performed according to different injury conditions. The time from injury to treatment was from 6 to 48 hours. The effect of classification of talus fracture and surgery methods on avascular necrosis was analyzed.

RESULTSIn 43 cases,19 cases occurred avascular necrosis, including talar neck fracture of type I in 2 cases, type II in 5 cases, type III in 5 cases, type IV in 5 cases and talar body fracture in 2 cases (combined with talar neck fracture). And 29 patients were treated with operation, there was no statistically significant differences in avascular necrosis with different operations.

CONCLUSIONCompared with talar body fracture, talar neck fracture is more easily to develop into avascular necrosis. In the 4 types of talar neck fracture, the possibilities of type III and IV were the most ones.

Objective To construct human phage antibody library against hepatoma carcinoma.Methods Peripheral blood mononuclear cells(PBMCs) of patients with liver cancer were sensitized in vitro and transformed by Epstein-Barr virus(EBV).The genes of light chain and Fd of antibodies were amplified by RT-PCR.Fab genes were cloned into vector pComb3 and transformed into E.coli XLI-Blue by electroporation to construct the Fab-displaying phage antibody library.Results ELISA detection showed that 4 liver cancer patients' B cells transformed by EBV could produce specific antibodies to hepatoma carcinoma cell.Totally 13 types of light chain genes and 28 types of Fd genes were obtained by RT-PCR.The capacity of the primary phage library was 1.7?107pfu/mL.The percentage of recombinant clones was about 100%.Conclusion A human phage antibody library has been constructed successfully by means of EBV transformation technique.

Objective To evaluate routine MR examination of the knee in diagnosing bucket-handle tears of the menisci.Methods The characteristic MRI findings of bucket-handle tear of menisci proved by arthroscopy in 38 cases were analysed.Results The fragments of bucket-handle tears mesially displaced and meniscus deficiency or part deficiency were showed in 30 cases.Five cases showed Ⅲ degree high signal intensity of meniscal tears.Three cases had no abnormal finidngs.Conclusion The MRI characteristic features of bucket-handle tears of the menisci are the fragment of bucket-handle tears mesially displaced and the deficience of the menisci.When the fragments teared had no mesially displace,only show Ⅲ degree high signal intensity in meniscal tears,and those tears extend to the up and lower surface of menisci.

Objective:To investigate the relationship between epicardial adipose tissue (EAT) thickness and left ventricular geometry in patients with obstructive sleep apnea syndrome (OSAS).Methods:Two hundred and twenty-one OSAS patients were enrolled consecutively from the First Hospital of Shanxi Medical University from January to December 2019. According to left ventricular mass index (LVMI) and relative wall thickness (RWT), OSAS patients were divided into 4 groups based on the left ventricular geometry: 110 with normal geometry (NG group), 56 with concentric remodeling (CR group), 32 with concentric hypertrophy (CH group), and 23 with eccentric hypertrophy (EH group). The patients were examineel by echocardiography, the left ventricular end diastolic diameter, LVMI, interventricular septal thickness, left ventricular posterior wall thickness, left ventricle ejcetion fraction, E/A were collected. Age, systolic blood pressure (SBP), diastolic blood pressure (DBP), apnea hypopnea index (AHI), nocturnal lowest oxygen saturation (Lowest-SaO 2), nocturnal mean oxygen saturation (Mean-SaO 2), the percentage of the time that oxygen desaturation below 90%(T90), oxygen desaturation index(ODI), triglyceride (TG), total cholesterol (TC), EAT thickness and the echocardiography parameters were compared among the four groups. The relationships between EAT thickness and the above-mentioned parameters and left ventricular geometry were analyzed by univariate and multivariate linear regressions. Results:①The higher EAT thickness was found in the CH group [(0.50±0.09)cm] and EH group [(0.46±0.07)cm] compared with the NG group [(0.33±0.11)cm] and CR group [(0.36±0.15)cm] (all P<0.05). In addition, age, SBP, DBP, AHI, ODI, T90, LVMI, RWT and E/A ratio were all significantly different among the groups (all P<0.05). ②Univariate linear regression analysis showed that EAT thickness was positively correlated with age, SBP, DBP, AHI, TG, TC and LVMI, RWT, left ventricular geometry, and negatively correlated with Mean-SaO 2 and Lowest-SaO 2. ③Multivariate linear regression analysis showed that EAT thickness was independently correlated with AHI, TG, TC and left ventricular geometry. Conclusions:EAT is independently related to abnormal left ventricular geometry, suggesting that EAT may be involved in the process of left ventricular remodeling.

OBJECTIVETo explore the therapeutic mechanism of Tiaoxin Recipe (TXR) and Bushen Recipe (BSR) in treating Alzheimer's disease (AD).

METHODSSixty patients with AD were divided into 3 groups according to their MMSE and ADL scores before treatment, using randomized block design. They were treated separately with TXR, BSR and Donepezil (Dp) for 12 weeks. The changes of MMSE score, ADL score, neuro-psychology amount table score, including FOM, RVR, DS and BD, as well as the overall operational evaluation before and after treatment were analyzed.

RESULTSThe recognition and daily life capacity of patients in the 3 groups were improved after treatment. MMSE score in the TXR group increased from 16.10 +/- 1.94 scores before treatment to 17.90 +/- 2.59 scores after treatment, in the BSR group, from 16.15 +/- 2.16 to 17.50 +/- 2.59, and in the Dp group, from 17.35 +/- 1.90 to 19.60 +/- 3.39, all showed significant difference (all P < 0.01). Change of ADL score showed that in TXR from 43.10 +/- 3.86 to 41.50 +/- 4.40, in the BSR group from 43.30 +/- 4.53 to 41.60 +/- 4.12 and in the Dp group, from 42.95 +/- 3.58 to 40.60 +/- 5.23, which also showed significant difference (P < 0.05 or P < 0.01). Moreover, increase of FOM, RVR and DS score was shown in the TXR and the Dp group, and increase of RVR and BD score was shown in the BSR group with significant difference in comparison of corresponding score before and after treatment, inter-groups comparison showed significant difference of FOM score between the BSR and the Dp group (P < 0.01). Overall operational evaluation (total effective rate) in the TXR group was 70%, in the BSR group 65% and in Dp group 75%, with no significant difference among them.

CONCLUSIONTXR and BSR are effective TCM drugs in treating AD.

Objective To improve the methods of making myocardial ischemia-reperfusion model and observe the changes of electrocardiogram and ultrastructure of myocardium in rats.Methods The chest of young male SD rats through the fourth intercostal space was opened,and the left coronary artery was tied with a silicagel tube,after 30 minutes,untied to perfuse.Changes of electrocardiogram were observed and recorded.After reperfusion,the levels of AST,LDH,and CK-MB were measured and the tissue samples of the infarct areas were examined by transmission electronic microscope.Results The 90 percent of total rats were made myocardial ischemia reperfusion model successfully.In myocardial ischemia reperfusion rats:the QRS wave of myocardial ischemia-reperfusion rats was much higher than that of control group;the level of cardiac enzymes increased;myocardial and vascular endothelial cells ultrastructure was damaged seriously.Conclusions The improvement of modus operandi is right.Ischemia reperfusion can cause evident damage of myocardial and vascular endothelial cells ultrastructure in rats,and damage of myocardial cells is more severe than vascular endothelial cells.
