OBJECTIVE:To study invalid medical order warned by Prescription automatic screening system (PASS),and to improve rational drug use monitoring. METHODS:The infusion medical order warned with black light,red light and orange light by PASS were extracted from Pharmacy intravenous admixture services(PIVAS)of our hospital during Oct. to Dec. 2014. Invalid warning items were analyzed statistically in respect of warning level,problem types and reasons. RESULTS & CONCLUSIONS:There are 3 392 warnings items,468 were invalid (13.80%) which include 10 items by black light,219 items by red light and 239 items by orange light;by problem types,there are 218 items of overdose and 136 items of repeated treatment,etc. The main causes of invalid warning include 191 items caused by wrong system prompt,126 items by incomplete system information,143 items by insufficient auditing standards,etc. There are still some defects of invalid warning in practical application of PASS. It is suggested that user and developer add the function of self-defined drug list or user-defined system data by,and unify auditing stan-dards of rational drug use,etc.,so as to timely update the system information,and improve the accuracy of software system moni-toring and warning function.

Objective Toinvestigate iodine nutrition,thyroid volume and function of children and women in high water iodine areas,and to discuss the cut-off point of water iodine level where should be defined as iodine excessive areas.Methods In iodine excessive townships in Xiaodian and Qingxu Counties of Taiyuan City,all villages were divided to 4 groups according to the concentration of iodine in drinking water:50 ～ ＜ 100 μg/L (Group A),100 ～ ＜ 150 μg/L(Group B),150 ～ ＜ 300 μg/L(Group C) and ≥300 μg/L(Group D),and 2-3 villages were randomly selected from each group as investigation sites.Two hundred children aged 8-10 and 60 women (20 pregnant women,20 breasffeeding women and 20 women of childbearing age,respectively) were sampled.Drinking water,edible salt and once random urine samples for each studying object were collected,and the iodine content was measured.The goiter volume of children aged 8-10 and triiodothyronine (FT3),free thyroxine (FT4),thyroid stimulating hormone (TSH) of women were determined.Results Totally 708 children and 236 women were selected as respondents who ate non-iodized salt.Iodine content in drinking water of children in groups A,B,C and D was 73.8,144.7,258.5 and 501.0 μg/L,respectively,and that of women was 73.8,144.7,242.7 and 485.9 μg/L,respectively.Median urinary iodine of children in groups A,B,C and D was 274.3,312.8,455.6 and 793.5 μg/L,respectively,and that of women was 238.3,235.2,371.6 and 641.6 μg/L,respectively.The median urinary iodine of children and women increased with increasing water content of iodine.The goiter rate of children was 5.6％ (11/196),13.2％ (25/189),12.6％ (20/158) and 10.9％ (18/165) for each group,respectively,which also increased with increasing water content of iodine.In groups A,C and D,the FT3 and FT4 levels[pmol/L:(3.70 ± 0.59),(14.01 ± 2.44); (3.43 ± 0.57),(12.87 ± 2.12); (3.42 ± 0.47),(12.66 ±1.78)] in pregnant woman were lower than those in breasffeeding women[pmol/L:(4.26 ± ±0.57),(14.73 ± 2.36;(4.28 ± 0.40),(14.77 ± 1.19); (4.36 ± 0.65),(15.66 ± 2.84)] and women of childbearing age[pmol/L:(4.80 ±0.50),(17.47 ± 2.11); (4.21 ± 0.48),(15.83 ± 1.64); (4.26 ± 0.52),(15.53 ± 1.81)].With increasing water content of iodine,FT4 level was decreasing and TSH level was increasing gradually in women.Conclusions When water iodine exceeds 100 μg/L,goiter rate of children has increased significantly.Iodine excessive women and children have appeared one after another with increasing water content of iodine.Women incidence of subclinical hypothyroidism risk has increased with increasing water content of iodine,and the detection rate of subclinical hypothyroidism is significantly higher when water iodine is higher than 300 μg/L.The cut-off point of iodine excessive areas should be descend from 150 μg/L to 100 μg/L.

BACKGROUND: Clinically, in patients undergoing hematopoietic stem cell transplantation (HSCT), human cytomegalovirus (HCMV) can be associated with delayed platelet engraftment, phenotypically abnormal peripheral blood leukocytes, and graft rejection, possibly through a direct viral effect on hematopoietic progenitor cells after HCMV infection. OBJECTIVE: To investigate the inhibitory effect of ganciclovir (GCV) on proliferation of colony forming unit (CFU) granulocyte-macrophage (CFU-GM), CFU-erythroid (CFU-E), CFU T-lymphocyte (CFU-TL), CFU-multipotential (CFU-Mix) and CFU-megakaryocyte (CFU-Mk) progenitor cells of cord blood (CB) and the protective effects on them. DESIGN: Contrast observational study.SETTING: Department of Molecular Biology, Affiliated Hospital of Luzhou Medical College.PARTICIPANTS: A total of 20 cord blood (CB) samples (with 10 mL for each sample) from fetal umbilical vein of normal term spontaneous delivery neonates were provided by the Department of Gynaecology and Obstetrics, Affiliated Hospital of Luzhou Medical College. All the patients were informed and agreed with the experiment.METHODS: The experiment was carried out in the Department of Molecular Biology, Affiliated Hospital of Luzhou Medical College from June 2004 to December 2006. Colony forming unit-assay was applied to observe the suppression effect of HCMV-AD169 strain on CFU-GM, CFU-E, CFU-TL, CFU-Mix and CFU-Mk of CB with the presence of GCV. The techniques of polymerase chain reaction (PCR) and fluorescence quantification PCR were used to demonstrate the existence of HCMV-AD169 DNA in the colony cells of cultured CFU-GM, CFU-E, CFU-TL, CFU-Mix and CFU-Mk. Normal progenitor cells culture system was regarded as blank control group; normal progenitor cells culture system with inactivated HCMV fluid as inactivated (IV) control group.MAIN OUTCOME MEASURES: ① The number and maintaining duration of colonies of cultured progenitor cells were counted by using a light inverted phase contrast microscope. ② The techniques of PCR and fluorescence quantification PCR were used to demonstrate the existence of HCMV-AD169 DNA in the colony cells of cultured progenitor cells.RESULTS: ① Number and lasting time of colonies: The numbers of CFU-GM, CFU-E, CFU-TL, CFU-Mix and CFU-Mk colonies in the HCMV infection group were significantly less than those in the blank control group (P < 0.01). The maintaining duration of colonies in the HCMV infection group was significantly shorter than that in the blank control group (P < 0.01). HCMV-DNA copies of colony cells of GCV group decreased significantly by using fluorescence quantification PCR compared with HCMV group (P < 0.01), while negative in blank control and inactivated control in CFU-MK and CFU-Mix. ② CFU Growth rate: The Growth rate of colonies was 37.4%, 74.2%, 40.1%, 67.4% and 38.9% of CFU-GM, CFU-E, CFU-TL, CFU-Mix and FU-MK, respectively. ③ CFU-HCMV-AD169 DNA: Fluorescence quantification PCR showed that nucleonic acid content of progenitor cells after GCV-affected HCMV infection was decreased as compared with that after HCMV infection (P < 0.01).CONCLUSION: The differentiation and proliferation of CFU-GM, CFU-E, CFU-TL, CFU-Mix and CFU-Mk are significantly inhibited after infected with CMV-AD169 strain. The growth of hematopoietic progenitor cell after HCMV-AD169 infection is promoted by GCV, which suggests that GCV has an effect of anti-HCMV in vitro.

Purpose To investigate epidemiology and clinical features of tumors and tumor-like lesions of the foot and ankle,as well as prognosis of malignant tumors.Methods A total of 170 patients,surgically treated for bone and soft tissue tumors of the feet and ankle between 1984 and 2009 in a tertiary referral center specializing in orthopedic oncology,were enrolled in this retrospective study.The age,gender,clinical feature,tumor types,anatomical sites,the correlation between tumor size and tumor types,and the prognosis of malignant tumor were analyzed.Results There were 91 males and 79 females,aged from 7months to 76 years (average,33.1 years).There were 51 cases of bone tumor and 119 cases of soft tissue tumor.Benign tumors commonly occurred in the second and third decades of life,with an average age of 29.54years,while most malignant tumors occurred in patients aged between 40 and 59 years,with an average age of 43.73 years.Skin lesion was a symptom implying malignance.Soft tissue tumor and benign tumor were the most common types in the foot and ankle.Giant cell tumor of the tendon sheath was the most common type among benign soft tissue tumors; subungual exostosis and enchondroma were the most common types among benign osseous tumors; while melanoma and synovial sarcoma were the most common types among malignant soft tissue lesions.Both primary and metastatic bone tumors were very rare.Forefoot was the most common site where foot and ankle tumors happened.There was no correlation between tumor size and types of soft tissue tumor,while there was a high correlation between tumor size and types of bone tumor.Among 44 patients with malignant tumor,16 patients underwent limb salvage surgery,while 28 patients underwent amputation.The mean duration of follow-up was 32.4 months.Six patients survived with no evidence of disease.The 5-year survival rate was 16.13％.Conclusion Benign and soft tissue tumors are the most common tumors in the foot and ankle.Most malignant tumors occur in patients over 40 years of age.Skin lesion is a useful symptom in diagnosing malignant tumor.Forefoot is the most common site where tumor happened.There is a high correlation between tumor size and tumor types.The prognosis of malignant tumor is very poor.

Objective　To study the role of TNFα in the plasm a and skin and IL-1 in the serum in the formation of secondary thrombosis after skin avulsion. Methods　After avulsive flap at size of 12 cm×4 cm was inflicted on the hind legs of pigs, skin specimens and venous blood sam ples were taken at various time points. The contents of TNFα in plasma and skin were determined with radio-immunoassay, and the activity of serum IL-1 wi th 3［H］-TdR. Results　The TNFα contents in the plasma and skin were increased significantly after avulsion（P<0.01），which were (41 5±24) ng/L and (298±18.5) ng/L respectively on the 3rd day after the injury. T he activity of IL-1 in the serum was increased (P<0.05) and was (2.59± 0.85 ) ng/L on day 3. Conclusion　The changes of TNFα contents and I L-1 activity in blood and skin play important roles in the inducetion and aggra vation of secondary tissue necrosis and early thrombosis after skin avulsion.

Objective To investigate the relationship between the resting heart rate (RHR) and target organ damage (TOD) in elderly patients with metabolic syndrome(MS). Methods 264 elderly patients with MS were divided into four groups according to the level of RHR: RHR1 group, RHR<65 beats/minute (bpm) (46 cases) ;RHR2 group, 65≤RHR<75 bpm (77 cases);RHR3 group, 75 bpm≤RHR<85 bpm (89 cases);RHR4 group, RHR≥85 bpm (52 cases).Electrocardiography, echocardiography, carotid uhrasonography, crcatinine clearance rate (Ccr) and quantitative assay of 24 hours' albuminuria were performed. Results (1) Compared with RHR1, RHR2 and RHR3 groups, RHR4 group showed higher levels of carotid intima-medial thickness (IMT), carotid arterial diameter (CAD), left ventricular mass index (LVMI) and albuminuria(P< 0.05 or P<0.01), and lower levels of left ventricular ejection fraction (LVEF) and Ccr (all P< 0.01). (2) The IMT, CAD, LVMI and albuminuria were positively correlated with RHR (r=0.33, 0.23, 0.61, 0.58, respectively, all P<0.01). However, the LVEF and Ccr were negatively correlated with RHR (r=-0.59, -0.51, all P<0.01). (3) Logistic multivariate analysis showed that RHR and pulse pressure (PP) had effects on myocardial hypertrophy, coronary heart disease, heart failure, cerebral stroke and renal dysfunction(P<0.05 or P<0.01). Except heart failure, PP played a more important role than RHR. Coneinsions RHR may be an independent risk factors for TOD in elderly patients with MS,and RHR regulation is important for the development of MS in the elderly.

Aim To study the effect of proteasome inhibitor MG132 on the expression of caspase-3 and apoptosis in cultured human umbilical vein endothelial cells.Methods Human umbilical vein endothelial cells was treated with MG132 (2,5 ?mol?L~(-1)) for 24 h. The apoptotic cells were determined by DNA fragment analysis and flow cytometric analysis. The level of caspase-3 mRNA was quantified by reverse transcription-polymerase chain reaction (RT-PCR). The protein contents of caspase-3 were analyzed by immunocytochemistry.Results The results showed that the increase of the degree of human umbilical vein endothelial cells apoptosis was concentration dependent. MG132 could up-regulate the gene/protein expression of caspase-3.Conclusions The results implicated that proteasome inhibitor MG132 induced human umbilical vein endothelial cells apoptosis by accumulation of caspase-3.
