Objective To explore continuous renal replacement therapy(CRRT) machine for plasma exchange in critical disease in children.Methods Retrospective study of 8 patients(8 month to 14 years,mean 5.7 years) and 32 plasma exchange treatments,after(adowble) lumen catheter inserted into the subclayian venous,using the Baxter BM25 machine with commercially available plasma filters.Results Five patients(3 ABO-incompatibility in bone marrow transplantation,1 thrombotic thrombocytopaenic purpura TTP,1 sepsis) gained full recovery.One systemic lupus erythematosus(SLE) and 1 sepsis experienced moderate improvement while 1 case of acute disseminated encephalomyelitis failed PE treatment.The average total exchange volume was 80-100 mL/kg,achieved at a blood flow rate of 5-10 mL/(kg?min) and a turnover rate of 60-120 mL/(kg?h) over a 3-hours duration.Thirty-one PE treatments were finished smoothly,one of which experienced the serious complication involving plasma filter.Conclusion Plasma exchange therapy is a safe and effective procedure for severe autoimmune abnormalities and pathogen removal in children.

Objective To compare three kinds of irradiation treatment plans for cervical and upper thoracic esophageal cancer,in order to arrived at proper decision for the patient.Methods From February 2001 to June 2004,43 such patients were studied with three different simulated treatment plans made including conformal plan,conventional four-field plan and conventional two-field plan for every one.All plans were evaluated with iso- dose curve and dose-volume histogram.Results GTV on 95% isodose curve was 99.5%,98.2% and 87.4% in conforaml plan,conventional four-field plan and conventional two-field plan,respectively;PTV_1 and PTV_2 on 95% isodose with 97.8%,97.2%,94.8% and 95.8%,86.6%,73.7%.The volume of＞20 Gy dose of left lung accepted was 18.6%,17.2% and 32.3%,in conformal plan,conventional four-field plan and conventional two-field plan,respectively;the right lung received 20.5%,19.9% and 35.5%.Conclusions Conformal plan is the best in radiotherapy,as it can provide ideal dose distribution of irradiated target with adequate protection of the normal tissues.Conventional four-field plan,being easy to carry out,can replace the conformal plan in most situations.Conventional two-field has the most uneven dose distribution and largest lung volume irradiated.

The leading cause of drug withdrawal from market and clinical trials failure is drug-induced liver injury (DILI). Varying clinical, histological and laboratory features of DILI, as well as undefined underlying mechanisms, hinder patients to be diagnosed in the early-stage of the disease and receive effective treatments. Conventional indicators, like serum transaminases and bilirubin, have inevitable limitations referring to sensitive prediction and specific detection of DILI. In order to reduce the occurrence of DILI, researchers have attempted to discover potential biomarkers with higher specificity and sensitivity from blood and urine in recent years. This article aims to review recent advances in biomarkers of DILI.

UNLABELLEDOBJECTIVE To investigate the effect of Nepsilon-(carboxymethyl) lysine albumin (CMLs), a primary advanced glycation end products (AGEPs) isoform in diabetic body, on the function and angiogenesis of adipose tissue-derived stem cells (ADSCs) and the protective effect of Danhong Injection (DH). METHODS Human ADSCs were cultured and separated from human subcutaneous fatty tissue using enzymatic digestion and centrifugation. The morphology was observed using optical microscope and differentiation capacities assessed. Cells were exposed to 5 different interventions respectively for 24 h, i.e., PBS, 60 1 microg/mL BSA, 60 microg/mL CML-BSA, 100 microL/mL DH, and 60 micro./mL CML-BSA +100 microL/mL DH. Their effect on the proliferation, migration, apoptosis, and secretion were observed using WST-1 assay, Transwell assay, Annexin V-FITC/PI flow meter test reagent kit, human VEGF reagent kit, ELISA reagent kit, respectively. The effect on ADSCs angiogenesis was observed by in vitro angiogenesis test.

RESULTSCompared with the BSA group, the capacities of proliferation and migration could be significantly inhibited by CML-BSA, the apoptosis promoted, the secretion of VEGF reduced, and the angiogenesis of ADSCs weakened (P < 0.05). Compared with the blank control group, 100 microL/mL DH could significantly promote the proliferation and migration capacities of ADSCs, inhibit apoptosis of ADSCs, increase the secretion of VEGF, and improve the angiogenesis of ADSCs (P < 0.05). Compared with the CML-BSA group, the inhibition of CML-BSA on the proliferation and migration capacities of ADSCs could be significantly reversed, the promotion of CML-BSA on the apoptosis of ADSCs improved, the secretion of VEGF increased, and the angiogenesis of ADSCs elevated (P < 0.05).

CONCLUSIONclusion CMLs could significantly inhibit the proliferation and migration capacities of ADSCs, promote their apoptosis, and inhibit their angiogeneses, which could be improved by DH.

OBJECTIVETo study the effects of astragaloside on the expression of insulin-like growth factor-1 (IGF-1) and associated proteins in mice with viral myocarditis.

METHODSSixty-five 4-week-old BALB/C mice were randomly divided into 5 groups: normal control, astragaloside control, untreated myocarditis, low-dose and high-dose astragaloside-treated myocarditis. The BALB/C mice in the later three groups were intraperitoneally injected with CVB3. The low-dose and high-dose astragaloside-treated myocarditis groups were given astragaloside of 0.07 and 0.6 mg/kg•d, respectively by intragastric administration. Fifteen days later, the samples of blood and muscular tissues were obtained. The expression of IGF-1 in plasma was measured using ELISA. The levels of IGF-1 and associated proteins in muscular tissues were measured by immunohistochemistry. The expression of IGF-1 mRNA in muscular tissues was examined by RT-polymerase chain reaction (RT-PCR).

RESULTSThe expression of IGF-1 and associated proteins increased significantly in mice infected with CVB3. High-dose astragaloside treatment reduced the expression of IGF-1 and associated proteins, but low-dose astragaloside did not.

CONCLUSIONSHigh-dose astragaloside may reduce the expression of IGF-1 and associated proteins in mice with acute viral myocarditis, possibly thus providing protective effects on muscular tissues.

Objective To investigate the changes of insulin-like growth factor-1(IGF-1) and its associated protein in Balb/C mice with viral myocarditis.Methods Sixty Balb/C mice were randomly divided into 2 groups:infected group(n=40) and control group(n=20).Mice in infected group were inoculated intraperitoneally with coxsackievirus B3(CVB3) while control mice with 0.1mL of Eagle′s minimal essential medium(EMEM).Blood and myocardial musculature of all mice were collected on the day of 3,7,15 and 30 after inoculation.The expression of IGF-1 and its associated protein in plasma or myocardium were detected respectively by enzyme-labeled immunosorbent assay(ELISA),immunohistochemistry and reverse transcription polymerase chain reaction(RT-PCR).Results The expression of IGF-1 and its associated protein of mice with viral myocarditis was higher than those in control group and gradual ascent after mice being infected with virus.The expression reached summit on d15,then decreased on d30,but still sustain in a high level.The difference was significant(F=19.53 P

OBJECTIVE: To investigate the main point of long backbone fracture caused by blunt force in forensic clinical identification and to provide a reference for the inspection and appraisal practices of such injury. METHODS: Ninety-nine cases of adult long backbone fractures were collected from January 2006 to December 2013 in Gutian County of Fujian Province. According to the terms of fracture location, mode of injury, type, the data were summarized. RESULTS: In the 99 cases, there were 36 cases caused by hitting, kicking, and falling and 63 cases caused by vehicle collision. The majority of the former was ulna, and those of the latter were tibia and fibula. The types of fracture were transverse one, short oblique one, long oblique one, and spiral one. CONCLUSION Different types of long backbone fracture, not only causing stress load of fractures as well as structural differences related to each segment.
