Based on the problems existing in the original specimen management process of the First Affiliated Hospital of Guangdong College of Pharmacy,the paper proposes achieving the closed-loop management process of laboratory specimens through wireless network technology,PDA,laboratory specimen bar code,QR codes of patients and interaction of multiple systems,and describes the functional design and application effect of the system.The application of the closed-loop management process for laboratory specimens can better standardize and normalize the management of specimens.

Objective To investigate the diagnostic threshold value and the influencing factors of high‐sensitivity troponin I measurement in the diagnosis of patients with acute myocardial infarction .Methods Collecting 9 236 patients who are the first time hs‐cTnI testing in the internal emergency department of our hospital(including 9 099 patients with non‐AMI and 137 patients with AMI) as participants ,then dividing non‐AMI patients into elder group(>60 years old) and younger group(≤60 years old) ,hs‐cTnI concentrations were compared between the elder and the younger group with different gender .The optimal threshold value of hs‐cT‐nI for acute myocardial infarction was determined by receiver operating characteristic(ROC) curve of AMI patients with different age and gender .Results The hs‐cTnI concentrations of non‐AMI patients in the elder male group were 39 .21 ng/L [(37 .48-40 .93)ng/L] ,which was higher than those of non‐AMI patients in the younger male group 22 .38 ng/L[(21 .16-23 .6)ng/L] and the difference was statistically significant(P<0 .05) ,the same result was seen in the elder female group and the younger female group .The total male group was 31 .26 ng/L [(30 .17 -32 .34)ng/L] ,it was higher than the total female group 26 .8 ng/L [(25 .73-27 .86)ng/L] .According to the ROC curve ,the optimal threshold value for AMI diagnosis was 45 ng/L in total AMI group and 135 ng/L in the elder male group and 45 ng/L in the elder female group ,which was different with the cut off value(120 ng/L) .Conclusion the hs‐cTnI levels were related with age and gender ,it is very important for us to consider these factors when we make the optimal threshold value with our own data .

[Methods] Orthogonal design was used to observe the influence of preparation conditions such as dry extract content, dry extract gram size, gel forming matrix and cooling agents on the quality of MDP. [Results] MDP made under the optimized conditions was good in shape, and color and luster, and not adhesive, indicating the good quality of the product. [Conclusion] This optimized preparation technology of MDP is simple with satisfied technique parameters and is suitable for mass production in the enterprises.

Objective To investigate the characteristics of bone mineral density (BMD) in the patients with maintenance hemodi‐alysis(M HD) and relevant influencing factors to achieve the purpose of early diagnosis of osteoporosis .Methods Seventy‐two pa‐tients undergoing MHD and 76 healthy individuals(control group) were selected .The BMD values of lumbar spine and hip were measured in all subjects by using the dual energy X‐ray absorptiometry(DEXA) .The abnormal situation of BMD and the change of serum bone metabolism indicators in the patients with M HD were analyzed .Then the related factors affecting BMD were further ex‐plored .Results Compared with healthy controls ,the average BMD of lumbar and hip joints in M HD patients was significantly de‐creased ,which in elderly women was most remarkable ,and the incidence of osteoporosis was also significantly increased (P<0 .05) . Meanwhile ,the serum detection results showed that the levels of AKP ,iPTH ,P ,osteocalcin(OC) ,procollagen 1 N‐terminal peptide (P1NP) and β‐crosslaps (β‐CTX) in the NHD patients were significantly increased ;however the levels of Vit D and Ca were markedly decreased .The correlation analysis results showed that BMD was positively correlated with BMI and blood Ca ,while neg‐atively correlated with age ,dialysis age ,serum AKP and OC levels .Conclusion M HD patients are easily to appear the osteoporosis phenomenon ,in which the gender ,age ,dialysis age ,BMI ,serum AKP ,Ca and OC are the factors affecting BMD .

Objective To explore the effect of risk management on the perioperative nursing of elderly patients undergoing cardiovascular surgery. Method Sixty-two elderly patients undergoing cardiovascular surgeries were managed by management, which included establishing risk management team, identity and evatuating risk factors, applying risk manadement. Result There was no nursing risk events among them. Conclusion For elderly patients with cardiovascular surgery, risk management can enhance nurses′ability of discerning, assessing and managing the nursing risks so that it is effective in avoiding possible risks, reducing nursing adverse events during perioperative period, improving nursing quality and ensuring the safety of surgery.

Smooth muscle cell (SMC) proliferation, platelet free calcium level and aggregation of experimental atherosclerotic rabbits were investigated in this study. Aortic SMC ofhyperlipidemic rabbits in vitro showed higher growth activity than did normal rabbit SMC. And also hyperlipidemic serum stimulated SMC to proliferate at a significantly greater rate than control serum. Moreover, the level of platelet free calcium and the platelet aggregation was also higher in hyperlipidemic rabbits, indicating that activitated platelets possibly release more PDGF to act as a stimulator to SMC proliferation and calcium is an important factor to activate platelets. Furthermore, SMC from 8501-treated rabbits appeared lower proliferative rate than thecells from hyperlipidemic rabbits. And serum from those rabbits inhibited SMC proliferation compared with hyperlipidemic serum, the inhibitory effect was even stronger than that of normal serum. It may be relevant to the favorable effects of 8501 to TXA2/PGI2 balance.

AIM: To investigate the effects and mechanisms of swainsonine-induced apoptosis on SGC-7901 cells. METHODES: After being treated with swainsonine, effective dose and median inhibition concentration (IC50) of swainsonine to SGC-7901 cells were examined by MTT assay. Cell cycle distribution and apoptotic rates were analyzed by flow cytometry. Expression of p53, c-myc and Bcl-2 were determined by immunocyto- chemical method, and the concentration of Ca2+ intra-cellular ([Ca2+]i ) was measured by the laser scanning confocal microscope (LSCM). RESULTS: Swainsonine inhibited cell growth of SGC-7901 in vitro, IC50 of 24 h was 0.84 μg·ml-l, and complete inhibition concentration of swainsonine was 6.2 μg·ml-l. Treated with swainsonine at the concentrations of 0.5, 1.5 and 4.5 μg·ml-l for 24 h, the expression of apoptosis inhibiting gene p53 and bcl-2 decreased, and apoptotic trigger gene c-myc increased (P<0.05), as well as [Ca2+]i overloading, SGC-7901 cell was induced to apoptosis in the end. The percentage of S phase were 38.8%, 39.7% and 29.6%, respectively (20.0% in control group and 23.2% in 5-Fu group), the percentage of G2/M phase were 4.5%, 1.7% and 5.3%, respectively (5.5% in control group and 9.0% in 5-Fu group), and the percentage of G1/M phase was not altered. SGC-7901 cells were treated by swainsonine at the concentrations of 0.5, 1.5 and 4.5 μg·ml-l for 24 h. Compared with the control group, the percentage of S phase were increased and that of G2/M cells were decreased significantly in treatment groups (P<0.01). CONCLUSION: Swainsonine can inhibit the cell proliferation and induce apoptosis of SGC-7901 cells, the mechanisms of swainsonine-induced apoptosis may related with [Ca2+]i overloading and expression of apoptosis-related genes.

Objective To study the clinical features of hyperkalemic periodic paralysis (hyperKPP) and the relationship with SCN4A gene in a Chinese family Methods The clinical features of 7 patients in a Chinese family with hyperKPP were summarized All 24 exons of SCN4A gene were screened with denaturing high performance liquid chromatography (DHPLC) technology, and then sequence analysis was performed on those with abnormal elution peak Results This family showed typical clinical features of hyperKPP but without myotonia Three mutations were found in exon 13, 23 and 24 respectively Linkage analysis and direct sequencing showed the mutation in exon 24 was a synonymous mutation The mutation in exon 23 was a missense mutation, but proved to be a benign polimophism; the mutation in exon 13 was proved leading to the best known amino acid exchange Thr704Met Conclusion SCN4A gene should be related to hyperKPP, and Thr704Met be responsible for hyperKPP in this Chinese family
