Objective To estimate the effect of open reduction and internal fixation for treating the trimalleolar fracture in the elderly.Methods 57 aged patients suffered from the trimalleolar fracture and were treated with internal fixation from January 2009 to June 2012.25 males and 32 females with an average age of 71.5 years ranged from 65 to 81 years were involved in this study.The supination-external rotation type were in 41 cases and pronation-external rotation type in 16 cases according to Lauge-hansen's classification.The posterior and lateral approach was taken for surgical procedure of lateral malleolar frature.The routine or locking plates were used to fix the fratures.The posterior malleolar fractures were usually fixed through the posterolateral approach as well.The screws or tension band fixation was selected for fixing the medial malleolar fragments.The parallel screwing fixation could be helpful for fixing the tibiofibular syndesmosis.Results The ankle function was evaluated by the criteria system of the American Orthopaedic Foot and Ankle Society (AOFAS).The efficacy was excellent in 23 patients,good in 24 patients,fair in 7 patients.The skin problems such as super facial infection and delayed union of incision were in 7 cases.Conclusions If choosing reasonable operation method and suitable internal plant,the open reduction and internal fixation has better effect in treating the trimalleolar fracture in the elderly,with fewer complications.

ObjectiveTo understand the clinical and microbiological characteristics of AIDS-associated bloodstream infection (BSI).MethodsThe clinical and laboratory ifndings of 143 cases of BSI in AIDS patients who were hospitalized during the period from 2013 to 2014 were retrospectively analyzed.ResultsThe prevalence of BSI in AIDS patients was 22.1%. The 143 patients were divided into two groups in terms of fungal or bacterial infection. The incidence of speciifc skin rashes, anemia, hepatosplenomegaly and lymph node enlargement in fungal infection group was higher than those in bacterial infection group (allP<0.05). CD4+ cell count, WBC, neutrophils, RBC, hemoglobin, and platelet count in fungal infection group were lower than those in bacterial infection group, while AST and Cr were the opposite (allP<0.05).Penicillium marneffei(84/143, 58.7%) was the most common pathogen isolated from AIDS-associated BSI, followed byEscherichia coli (10/143, 7.0%),Cryptococcus neoformans (9/143, 6.3%),Klebsiella pneumoniae (7/143, 4.9%),Salmonella (6/143, 4.2%),Candida albicans(3/143, 2.1%), andAeromonas (3/143, 2.1%). Most strains were still susceptible to the commonly used antibiotics.ConclusionsThe prevalence of BSI is high in AIDS patients. Fungal BSI is more likely to have skin rash, anemia, hepatosplenomegaly and lymphadenopathy, hematologic abnormalities, liver and renal function impairment. Fungi, especiallyPenicillium marneffei, are the main pathogen of AIDS-associated BSI. Most strains are susceptible to the commonly used antibiotics.

OBJECTIVE:To compare the clinical efficacy and safety of Kangshuling gel,mupirocin and lactate ethacridine in the treatment of diabetic foot. METHODS:90 patients with diabetic foot were randomly divided into Kangshuling group,mupiro-cin group and lactate ethacridine group. All the patients were treated by lowing blood glucose,nutritional support,improving micro-circulation and anti-infection,etc. On this basis,3 groups were given Kangshuling gel,Mupirocin ointment and Lactate ethacridine solution for wet compress by gauze. The course was 180 d. The clinic data was observed,including clinical efficacy,and wound ar-ea,healed patients’granulation,epithelial tissue,healing time and incidence of adverse reactions before and after treatment. RE-SULTS:The total effective rate in Kangshuling group was significantly higher than mupirocin group and lactate ethacridine group;healed patients’granulation,epithelial tissue and healing time were significantly shorter than mupirocin group and lactate ethacri-dine group,with significant differences(P<0.05). After treatment,wound area in each group were significantly smaller than be-fore,and Kangshuling group was smaller than mupirocin group and lactate ethacridine group,with significant differences(P<0.05);there were no significant differences between mupirocin group and lactate ethacridine group(P>0.05). There were no obvi-ous adverse reactions during treatment. CONCLUSIONS:Based on the conventional treatment,Kangshuling gel has better efficacy than mupirocin and lactate ethacridine in the treatment of diabetic foot,with good safety.

OBJECTIVE:To explore the clinical features and regularity of drug-induced liver injury (DILI),and to provide reference for clinical rational drug use. METHODS:104 DILI cases in our hospital from 2005 to 2014 were selected and analyzed retrospectively in respects of patient’s gender,age,allergic history,medication history,drug type and clinical manifestations. RE-SULTS:DILI hospitalized cases increased year by year. There were 47 males and 57 females,and average age was(8.71±13.90). The clinical symptoms appeared within 12 weeks after using the drug. The symptoms were no specific,including weak,anorexia, jaundice,yellow urine,etc. and 10.57% of patients were asymptomatic. Most of the DILI cases were hepatocyte type(80.77%), followed by cholestasis type(12.50%)and hybrid type(6.73%). The most common cause of drug-induced liver injury were TCM, antimicrobial drugs and the nervous system drugs. CONCLUSIONS:The incidence of DILI in females is slightly higher than males. DILI often occurs after 40 years old. The clinical symptoms have no specificity and are similar to viral hepatitis. The hepatic lesions can be caused by most of drugs. DILI by TCM should concerned. Clinical physicians should pay more attention to DILI.

Objective To explore the application of single-person operated mammotome minimally inva-sive surgery in treatment of benign breast lesions. Methods Clinical information of 403 patients were collected and retrospectively analyzed. 262 patients receiving ultrasound guided single-person operated mammotome mini-mally invasive surgery for benign breast masses were selected as the treatment group,141 patients undergoing open surgery for treatment of benign breast masses were selected as the control group.Operative time, introopera-tive blood loss,length of stay,postoperative healing time, as well as the occurrence of complications were com-pared between the two groups. Result Compared with the control group, the operative time was shorter, the in traoperative blood loss was less, the scar size and the postoperative healing time were shorter for the treatment group. The difference had statistical significance (P<0.05).The rate of postoperative pain, local ecchymosis, local infection and breast deformity for the treatment group was significantly lower than those of the control group (P<0.05). The difference had statistical significance (P<0.05). The recurrence rate between the two groups had no sta-tistical significance (P>0.05). Conclusions Single-person operated Mammotome minimally invasive surgery has the advantages of good operative time,good cosmetic effects, small surgical trauma, less blood loss, fast postoper-ative healing and few complications, which is worthy of clinical application.

Objective To investigate the feasibility of magnetic resonance diffusion-weighted intravoxel incoherent motion (DW-IVIM)imaging and its reproducibility in normal liver.Methods Thirty-five young healthy volunteers underwent liver DW-IVIM ex-amination twice on a 1 .5 Tesla Philips MR scanner.Parameter maps of D,D* and f were generated by using a manufacturer-sup-plied software.Six Region-of-interests (ROIs)(3 ROIs in left and right liver lobe,respectively)were drawn on three consecutive middle slices,respectively.The average values of D,D* and f were measured and compared between the left and right liver lobe. The reproducibility of D,D* and f measurement were assessed with Bland-Altman method.Results The values of D,D* and f of left liver lobe [D(×10-3 mm2/s):1.250±0.210,D*(×10-3 mm2/s):101.906±15.063 ,f(%):22.954±5.268]were statistically higher than those of right liver lobe[D(×10-3 mm2/s):1.039±0.124,D*(×10-3 mm2/s):100.127±20.757,f(%),18.317± 3.671](D,f,P<0.001,D*,P<0.232-0.605),however ,their reproducibility of left liver lobe [limit of agreement(LOA):22.55%,51.05%,39.3%,respectively]were lower than those of right liver lobe (LOA:20.3%,39.25%,33.9%).The D values had the best reproducibility in both the left and right liver lobe.Conclusion The liver DW-IVIM is feasible.The values of D,D*and f in left liver lobe were higher that those in right liver lobe but with worse reproducibility of measurement.The D value was most reproducible in both liver lobes.

In order to reveal the treatment mechanism of Chinese medicine with the effect of activating blood and resolving putridity, we selected acetyl-11-keto-beta-boswellic acid (AKBA) and arsenic trioxide (ATO), the main monomeric components of frankincense and arsenolite which are two most commonly used Chinese medicine with effect of activating blood and resolving putridity. We combined AKBA and ATO as a compound, and explored its regulatory role in productions and activities of matrix metalloproteinase (MMP)-1, MMP-2 and MMP-9 in human skin fibroblasts (HSFbs) and human acute monocytic leukemia cell line THP-1 in inflammatory state.

Purpose To investigate the effect of two different 1.5T MRI scanners on the apparent diffusion coefficient (ADC) measurement and its reproducibility in diffusion weighted imaging (DWI) of the liver. Materials and Methods Two groups of volunteers (33 people in each group) underwent liver DWI examination twice by using the same DWI sequence with b value of 0 and 800 s/mm2 on different MRI scanners (1.5T Siemens Espree and 1.5T Philips Achieva). On ADC maps, two region of interests were placed on three central slices of the left and right liver lobes, respectively. The ADC measurements of six region of interests on left and right liver lobes were averaged to represent the mean ADC values of the left and right liver lobe, respectively. The reproducibility of the ADC measurements was assessed by Bland-Altman method. Results The ADC values of the left and right liver lobes measured on Siemens MRI scanner were significantly higher than those on Philips MRI scanner (t=2.045-2.713, P<0.05); on both scanners, the ADC values of the left liver lobe were significantly higher than those of the right liver lobe (t=-10.561--7.263, P<0.001). The Bland-Altman results showed that the reproducibility of ADC measurement was similar on both MRI scanners, and both displayed higher reproducibility of right liver lobe than that of left liver lobe (on Siemens MRI scanner: the agreement were 16.65% and 7.55% for the left and right liver lobe, respectively;and on Philips MRI scanner:16.30%and 7.85%, respectively. Conclusion Different MRI scanners may have influence on ADC values, but does not affect its reproducibility. Therefore, when ADC values obtained on different MR scanners are compared in clinical analysis, this influence should be considered.
