OBJECTIVE:To reduce the error rate of inventory in the automated pharmacy of our hospital. METHODS:Activi-ties were designed and implemented by the management method of quality control circles(QCC)-PDCA(Plan,Do,Check and Ac-tion)cycle. The reasons for the errors of inventory in the automated pharmacy were analyzed to investigate and implement counter-measures. Visible and invisible achievements were evaluated,and then standardized processes were made. RESULTS:The errors of inventory in the automated pharmacy mainly included those of drug dispensing,drug shelving,drug return sheet,automatic medi-cine dispensing machine and system. In view of the above reasons,relevant standards were formulated and performed,including the process of warehouse-out check and shelving of drugs,drug dispensing process for the automated pharmacy,the process of sec-ondary check,etc. After the implementation of the activities,the error rate of inventory in the automated pharmacy reduced from 9.17% to 3.77%,which was visible achievement;and the above-mentioned standardized processes could ensure continuous run-ning of PDCA cycle. The practice,sense of responsibility,communication and coordination of management members in PDCA cy-cle namely invisible achievements were improved to some extent. CONCLUSIONS:The management method of QCC-PDCA cycle is feasible in reduction of the error rate of inventory in the automated pharmacy,which can provide a reference for automated phar-macy management.

In order to investigate the interelationship between copper deficiency and lipidemia, an experiment was done in weanling rats fed normol and copper deficient diet for one month. At the end of experimental period, the growth rate, the contents of copper, zinc, cholesterol and triglyceride in plasma and the activity of monoamine oxidase (MAO) in plasma were measured. The differences between the two diets were compared by student's test and the relation between plasma copper and plasma cholesterol or MAO was ascertained by regression analysis.The results showed that a lower body weight gain and a highly significant hypercholesterolemia were found in copper deficiency rats and the plasma cholesterol concentration correlated reversely with the plasma copper (r = -0.724, p

Aim To evaluate the efficacy of TFU as a precursor of 5-FU on the growth inhibition of human gastric carcinoma cell lines SGC-7901 and MKN-45.Methods In vitro experiments,cell growth inhibition was measured by MTT assay.The rates were compared in the presence and Absence of liver microsomal enzymes.The morphology of apoptotic cells was detected by observation with a fluorescence microscope after staining by using adridine orange/ethidium bromide solution.DNA fragmentation was analyzed by agarose gel electrophoresis and flow cytometry respectively.Western blot was employed to analyze the expression of Bcl-2 and Bax.The in vivo efficacy of TFU was assessed in nude mice bearing tumours.The specimens were re-moved and the in situ cell apoptosis detection kit was employed for TUNEL staining.Results Growth of SGC-7901 and MKN-45 cells was remarkably suppressed by treatment with TFU in the presence of liver microsomal enzymes in vitro,suggesting that TFU might be converted to 5-FU by the enzymes.Similar treatment of TFU induced apoptosis of the cells,which was deduced from typical apoptotic features such as morphology,the formation of characteristic ladder pattern of DNA migration and the accumulation of sub-G1 phase.Furthermore,a significant inhibition of Bcl-2 expression and the up-regulation of Bax were observed after treatment with TFU in the presence of liver microsomal enzymes.Growth of human gastric carcinoma cells was significantly delayed by oral administration of TFU with low side effects.Apoptosis in xenografts was also observed by means of TUNEL staining method.Conclusion Treatment of TFU in the presence of liver microsomal enzymes could promote the inhibition of gastric carcinoma cell proliferation.TFU might sustain release of 5-FU mediated by liver microsomal enzymes.Low dose of 5-FU might trigger the carcinoma cells apoptosis via regulation of Bax and Bcl-2.

Objective To study the clinical manifestation,diagnosis and treatment of the renal myxofibromata.Methods Combined with reviewing the relevant literature,we retrospectively analyzed the clinical data of a case of renal myxofibromata.A 47-year-old female patient was found left renal cystic lesion by ultrasound 8 months before admission.CT showed a 4 cm cystic and solid lesions in the lower pole of left kidney,which was similar to the results of ultrasound.The enhanced abdominal CT and dynamic contrast-enhanced ultrasound showed that the lesions could be enhanced slowly with uneven density.The patient underwent left kidney exploration under the general anaesthesia.During operation,a round solid mass about 5 cm in diameter can been seen in the low part of renal sinus,which was a bit hard.The mass was close with surrounding tissue.Then,the left kidney was excised.Results The surface of the mass was full and smooth with pale yellow luster.In the HE section,the tumor was composed with fibroma like cell,which demonstrated the inhomogeneous size,shape and irregular organization.The nucleus showed the spindle shape,with rare mitosis phase.Large quantity of mucus and vascular tissue could be observed in the tumor.Few fibroblast cells could also be found in the section.The pathological result was myxofibromata (immature) with malignant tendency.No special treatment was given after surgery.Recurrence was not recorded within 6 months following-up.Conclusions Commonly,the myxofibromata is a kind of benign tumor.Only a few can result in the malignant transformation and distant metastasis.Primary renal myxofibromata is extremely rare.The preoperative imagine manifestation is difficult to provide the accurate diagnosis.Pathologic result is the gold standard in diagnosing this disease.Actively surgical treatment and regular following-up after surgery should be considered.

BACKGROUND: Lower extremity deep venous thrombosis is commonly seen after hip arthroplasty. The time of thrombosis after arthroplasty in senile patients with osteoporotic femoral neck fractures is little reported.OBJECTIVE: To investigate the time of perioperative lower extremity deep venous thrombosis in senile patients with osteoporotic femoral neck fractures undergoing hip arthroplasty. METHODS: The data of 178 patients with femoral neck fractures undergoing hip arthroplasty were analyzed, and were then allocated to anticoagulant and non-anticoagulant groups according to the preoperative use of low-molecular-weight heparins or not. Doppler ultrasonography of both lower extremity arteries was conducted at 1, 3, 5 and 5-7 days after injury, and 2, 5, 7 and 14 days postoperatively to monitor the lower extremity deep venous thrombosis, and the number and incidence of thrombosis in the two groups were recorded at different time points. The time of thrombosis occurred frequently after injury and surgery was determined through drawing the frequency distribution table and line chart.RESULTS AND CONCLUSION: (1) The incidence of thrombosis showed significant difference between anticoagulant (n=6, 8%) and non-anticoagulant (n=22, 21%)) groups (P < 0.05). (2) Thrombosis frequently occurred at 3 days after injury and 1 day postoperatively. (3) These results suggest that the thrombosis in patients with femoral neck fractures frequently occurs at 1-3 days after injury and 1 day after replacement. Additionally, active prevention measures after injury can significantly reduce the incidence of lower extremity venous thrombosis.

Objective To systematically evaluate the clinical effect of prone position mechanical ventilation on the improvement of oxygenation in patients with severe pneumonia. Methods Pubmed, Embase, Cochrane Library, CNKI, Wanfang Data and VIP database were searched from the time of database built up until December 10th, 2017. All the published randomized controlled trials (RCTs) about the effects of prone position ventilation on the oxygenation of severe pneumonia patients were screened, and were confirmed by the literature reference citation retrieval. Inclusion and exclusion criteria had been used to review and rank the literature. After evaluating the quality of included studies, the data was extracted from RCTs and given a Meta-analysis using RevMen 5.1. Results Twelve RCTs with 650 cases were included. Eleven of them were Chinese literature while 1 was in English. Ten studies showed that the prone position ventilation had a significant influence on improving partial pressure of oxygen [weighted mean difference (WMD) =9.93, 95% confidence interval (95%CI) = 2.92-16.95, P = 0.006], publication bias was found in these studies. Seven studies showed that the prone position ventilation had a significant influence on partial pressure of carbon dioxide (WMD =9.99, 95%CI = 1.81-18.18, P = 0.02), publication bias was found in these studies. Seven studies showed that the prone position ventilation had a significant influence on oxygenation index (WMD = 31.22, 95%CI = 26.06-36.39, P < 0.000 01), publication bias was found in these studies. Two studies showed that the prone position ventilation had a significant influence on oxygen saturation of blood (WMD = 2.12, 95%CI = 1.24-3.00, P < 0.000 01), no publication bias was found in these studies. Conclusion Prone position ventilation can effectively improve the patients' oxygenation index, partial pressure of oxygen, and oxygen saturation of blood, and reduce the partial pressure of carbon dioxide.
