Objective To study the efficacy and side effects of Ganciclovir combined with L-ornithine-L-aspartate on infant cytomegalovirus(CMV) hepatitis.Methods Sixty infants with CMV hepatitis hospitalized in our hospital from Dec.2009 to Dec.2010 were treated with ganciclovir combined with L-ornithine-L- aspartate.The parameters observed in the study included the pre-and post-treatment data on total Bilirubin (TBIL),alanine aminotransferase (ALT),alkaline Phosphatase (AKP)and the retraction of liver and spleen,as well as the adverse reactions of the treatment.Results The treatment significantly decreased serum TBIL (t =5.74,P ＜ 0.05 ),ALT( t =2.92,P ＜ 0.05 ) and liver( t =8.27 P ＜ 0.05 ) and spleen volume ( t =5.03,P ＜0.05).However,side effects such as liver damage and rash occurred occasionally during the ganciclovir treatment.Intravenous infusion of L-omithine-L-aspartate caused side effects such as vomiting and other mild gastrointestinal reactions.Conclusion The treatment of Ganciclovir combined with L-ornithine-L-aspartate on infant cytomegalovirus hepatitis created good efficacy and can be considered as the first treatment choice.Though it is relatively safe,adverse reactions should be monitored during the treatment.

ObjectiveTo identify serum specific protein biomarkers for the early diagnosis of lymphoma patients by using surface enhanced laser desorption/ionization time of flight mass spectrometry (SELDI-TOF-MS)protein chip array.MethodsSELDI-TOF-MS technique and weak cation exchanger (WCX2)protein chip were used to detect the serum proteomic patterns of 96 patients with lymphoma (86 patients with non-Hodgkin lymphoma and 10 patients with Hodgkin lymphoma)and 30 normal control.The serum level of LDH were measured by biochemical methods,the serum level of β2-MG and CA125 were detected by enzyme-linked immunosorbent assay (ELISA).ResultsFour protein peaks pattern mass/charge ratio (M/Z) 6880,8564,8692 and 13751 were decreased in lymphoma patients,and they could be used to distinguish lymphoma from healthy people and other malignant tumors.Their sensitivity and specificity were 82.29 ％ and 80.00 ％,78.13 ％ and 73.30 ％,75.00 ％ and 80.00 ％,71.88 ％ and 83.30 ％ respectively in lymphoma patients.When it was used to early diagnosing lymphoma in stage Ⅰ or Ⅱ,the sensitivity of four protein peaks pattern (M/Z 6880,8564,8692 and 13 751) were 77.55 ％,71.43 ％,71.43 ％ and 67.35 ％respectively and the specificity of all four protein peaks pattern were 100.00 ％.Four protein peaks pattern sensitivity were higher than LDH,CA125 and β2-MG respectively.ConclusionApplication of SELDI-TOF-MS can be of great potential for the early diagnosis of lymphoma patients.

Objective To report the outcome of emergency repair of severe complex defect in forearm by transplantation of free flap and simultaneous functional reconstruction.Methods From Mar.1994 to Aug.2003,4 cases with severe complex defect in forearm was repaired by transplantation of free skin flap, free skin flap combined with fibula flap,or fibula osteocutaneous flap in emergency.Simultaneously the flexion and extension function were repaired by muscle transfer and/or tendon grafting,tenonectomy.Results All the cases were successful.Follow-up period ranged from 1 to 3 years postoperatively.The blood-supply,tex- ture and elasticity of transferred flaps were excellent with good bone healing.Opposition of thumb with four fin- gers was good.Sensory recovery of the hand was satisfactory.Conclusion Transplantation of free flap com- bined with simultaneous functional reconstruction is an ideal method in emergency repair of severe complex de- fect in forearm.

The aim of this study is to investigate the anti-inflammatory effect of the adenosine derivative N6-(3-hydroxylaniline) adenosine (WS070117M1) on cigarette smoke plus LPS (lipopolysaccharide)-induced chronic obstructive pulmonary disease (COPD) in mice and its mechanism. COPD model was established by exposing male BALB/c mice to cigarette smoke and challenged with LPS inhalation. Supernatants of bronchoalveolar lavage fluid (BALF) were harvested and IL-1β, IL-6, IL-8 and TGF-β1 levels were measured by ELISA (enzyme-linked immunesorbent assay). The number of total white blood cells and neutrophils in bronchoalveolar lavage fluid was counted separately. Lung tissue was stained with Mayer 's hematoxylin and eosin for histopathologic examination. pAMPKa protein expression and distribution of lung tissue were analyzed by immunohistochemistry method. In vitro, levels of AMPKα phosphorylation in phorbol-12- myristate-13-acetate (PMA) differentiated THP-1 cells was detected by immunohistochemistry, IL-8 level in supernatants of cigarette smoke condensate stimulating PMA differentiated THP-1 cells was measured by ELISA. The results showed that WS070117M1 treatment significantly activated AMPKa in the lung tissue. It also resulted in down regulation of IL-1β, IL-6, IL-8 and TGF-β1 levels in bronchoalveolar lavage fluid and IL-8 level in cigarette smoke condensate stimulating PMA differentiated THP-1 cells. In addition, WS070117M1 could inhibit the recruitment of total white blood cells and neutrophils. These results suggest that WS070117M1 may alleviate the airway inflammation by activating AMPK in the lung tissue.

BACKGROUNDIt is still controversial whether or not the correlation between lipid abnormality and coronary heart disease (CHD) becomes weaker in the elderly, and whether patients above 80 years old still benefit from lipid management for the secondary prevention of CHD. The purpose of this study is to assess the correlation between hyperlipidemia and the risk of CHD events in the elderly, and to determine if it is appropriate to use lipid-lowering drugs in those aged above 80, as prescribed by the recommended guidelines for lipid management.

METHODSOne thousand two hundred and eleven retirees, mainly males (92%), aged 70 +/- 9 years, were enrolled in this study. Lifestyle habits and medical history were recorded via questionnaires. During the period 1986 - 2000, all subjects participated in an annual physical examination with a blood chemistry survey. The mean follow-up period was 11.2 years. Subjects with incidental illnesses, especially cardiovascular diseases, were diagnosed or treated promptly. Serum lipid parameters, including total cholesterol (TC), low and high-density lipoprotein cholesterol (LDL-C and HDL-C) and triglyceride (TG) levels were analyzed according to standardization of lipid and lipoprotein measurements. The association between lipid levels and the prevalence of acute myocardial infarction (AMI) or coronary death was analyzed statistically.

RESULTSLipid abnormalities occurred in 2/3 of the 1211 subjects. The most common lipid disorder was high TC and high LDL-C, which was much more prevalent than high TG. Among the subjects, 51.6% had TC levels above 5.2 mmol/L. Mean TC and LDL-C reached peak levels in the 65 - 74 age group without significant decrease until ages over 90. The cumulative total number of deaths due to various causes was 397 in the 15-year follow-up period, with the mortality rate in the high lipid group slightly lower than that in the normal lipid group (30.6% vs 35.3%), although the difference was not significant (P = 0.1931). However, there were more cases of coronary death in the high lipid group than in the normal lipid group (7.9% vs 4.6%, P = 0.0045). When examining AMI survivors, more AMI cases were found in the high lipid group than in the low lipid group (20.9% vs 11.4%, P < 0.0001). The cumulative number of coronary deaths was 89 (with 88 cases above age 70), and the total number of CHD cases was 214 (17.7% of the whole group). Logistic regression analysis reveals that age, hypertension, LDL-C, and HDL-C are important risk factors for CHD. Lifestyle changes were common, but only 45% of the hyperlipidemic cases received drug treatment. Statins were commonly used only in recent years.

CONCLUSIONThe above results show that high TC and LDL-C levels are correlated with a high CHD risk even in people over 80. For elderly patients with clinical CHD and an aggregation of CHD risk factors, cholesterol-lowering therapy might be considered if the general health of the patient makes this permissible.

BACKGROUNDResistin, a novel adipokine linked to insulin resistance and obesity in rodents, which is derived mainly from macrophages and identified in atheromas in human, has been shown to play a potential role in atherosclerosis. Resistin levels were reported to increase in coronary artery disease (CAD), while data concerning resistin in different stages of CAD in Chinese people are lacking. The aim of this study was to assess whether plasma concentrations of resistin differed between patients with unstable and stable angina pectoris.

METHODSPlasma resistin levels were determined by means of enzyme-linked immunosorbent assay (ELISA) in 46 patients with unstable angina (UAP), 37 with stable angina (SAP) and 31 control subjects.

RESULTSPlasma concentrations of resistin were significantly increased in UAP group (geometric mean (interquartile range) 12.09 ng/ml (8.40, 18.08)) in comparison with SAP (9.04 ng/ml (7.09, 11.44)) and control groups (8.71 ng/ml (6.58, 11.56)). No differences in resistin levels were found between patients with SAP and controls. We also found that plasma resistin positively correlated with leukocyte counts (r = 0.21, P = 0.027), high sensitive C-reactive protein (hs-CRP) (r = 0.25, P = 0.008), and endothelin-1 (r = 0.21, P = 0.025) after adjustment for age, sex and BMI.

CONCLUSIONResistin may be involved in the development of CAD by influencing systemic inflammation and endothelial activation.

OBJECTIVETo retrospectively analyses the results of dynamic axial external fixator with modified technique in the treatment of severely Pilon fractures.

METHODSFrom July 2000 to February 2003, 14 patients with severely Pilon fractures were treated with dynamic axial external fixator inserted with modified technique combined with limited open reduction and internal fixation with screws and Kirschner wires, with two distal external pins inserted into talus and calcaneus respectively so that the rotation axis of distal clamp was coincided with that of ankle joint. All patients were young or middle-aged people from 20 y to 52 y (average 38 y). All fractures were Rüedi-Allg were type II or type III. External fixators were removed after bone healing. Duration of follow-up was 5 - 36 m (average 18 m).

RESULTSThe time of bone healing was 12 - 24 weeks (average 14 weeks). At the latest follow-up, results include 5 excellent, 6 good and 3 fair according to ankle scoring system (ASS). There was only one case of superficial pin site infection settled with oral antibiotics and pin site care with mild disinfectants. There was no wound breakdown, superficial and deep infection, osteomyelitis, fracture fragments redisplacement and collapse.

CONCLUSIONDynamic axial external fixator with modified technique combined with limited internal fixation is an effective method for the treatment of severely Pilon fractures.
