Objective To explore the role of clinical pharmacists in nutrition support therapy in the patients with hyperemesis gravidarum. Methods The clinical pharmacist played a positive role in nutrition support care of a patient with hyperemesis gravidarum by analysising disease characteristics and adverse drug reactions, providing suggestion on the selection of fat emulsion and offering an individualized pharmaceutical care. Results The clinical pharmacist recognized the potential risk in nutrition support plan, took modifications timely, and prevented the occurrence of unfavorable clinical outcomes. Conclusion The participation of clinical pharmacists in nutrition support therapy of the patients with hyperemesis gravidarum is beneficial to improve the efficacy and safety of nutrition support and promote the rational use of drugs.

Objective To investigate the effects of down-regulation of Netrin-1 expression on cell proliferation,apoptosis and migration of a cutaneous squamous cell carcinoma(CSCC)cell line SCL-1.Methods Unspecific(control)small interference RNA(siRNA)and Netrin-1-targeting siRNA were designed and constructed.SCL-1 cells were divided into 3 groups to remain untreated(control group 1),be transfected with control siRNA(control group 2)and Netrin-l-targeting siRNA(experiment group)by using Lipofectamine 2000 respectively.After 48 hours of additional culture,flow cytometry was performed to detect the apoptosis of cells,Western blot to determine the protein expression of caspase-3 and-9,Netrin-1 and matrix metalloproteinases (MMP)in these cells,and Boyden chamber was utilized to evaluate the migration of cells.Enzyme linked immunosorbent assay(ELISA)was performed with cholecystokinin-8(CCK-8)kit to estimate the proliferation of cells at 24,48,72 and 96 hours after the transfection.Results The expression of Netrin-1 protein was significantly downregulated in SCL-1 cells in the experiment group compared with the control group 1 and 2 (0.207 ± 0.044 vs.0.741 ± 0.111 and 0.716 ± 0.109,F =31.43,P ＜ 0.05).The Netrin-1-targeting siRNA significantly downregulated the proliferation of SCL-1 cells,but induced the apoptosis in SCL-1 cells with significant differences in the percentage of early apoptotic cells and late apoptotic cells between the control group 1,2 and experiment group(11.74 ± 0.33 vs.11.55 ± 1.22 vs.24.74 ± 2.43,F=68.63,P＜ 0.01;3.82 ± 0.32 vs.4.69 ± 0.68 vs.5.33 ± 0.18,F =8.58,P ＜ 0.05).The experiment group showed a significant increase in the expression of caspase-3 and-9(1.458 ± 0.111 vs.0.398 ± 0.057 and 0.412 ± 0.049,F =183.99,P ＜ 0.01;0.967 ± 0.099 vs.0.234 ± 0.036 and 0.205 ± 0.033,F =138.11,P ＜ 0.01),but a statistical decrease in the expression of MMP-2(0.235 ± 0.038 vs.0.862 ± 0.040 and 0.892 ± 0.035,F =291.07,P ＜ 0.01)compared with the control group 1 and 2.Conclusions The down-regulation of Netrin-1 expression can suppress the proliferation and migration of SCL-1 cells,but promote the apoptosis in SCL-1 cells.

ObjectiveTo study the clinical effect of locking compression plate fixation in treatment of the elders with unstable fractures of the distal radius. Methods17 cases with unstable distal radius fractures were treated by volar locking compression plate. The function of the carpal joints and the bone healing conditions were evaluated after operations. ResultsAll cases were followed-up for 7 to 16 months ( mean 12. 6 months). Union was obtained in all the patients after 11.4 weeks. The clinical outcomes were evaluated according to modified X-rays and wrist assessment. 12 cases were graded as excellent and 4 as good. 1 case were graded as poor. The overall satisfactory rate was 94. 1％. ConclusionThe unstable distal radial fractures could be effectively treated with open reduction and LCP fixation through volar approach.

Objective To deduce the interactions between genes from time series microarray data.Methods We used inter-transaction association rules mining technique and GO (Gene Ontology) annotation to analyze the microarray data. Results Using 2-fold-change method, 119 differential expression genes were identified from total 10 080 genes or ESTs, whose expression levels varied significantly on 6 periods of fetus cerebellar development. As a result, about 1 300 inter-transaction association rules were extracted and 10 top rules were kept for their maximum J-measure values. A genes association network graph was deduced based on the 10 top rules. Conclusion Inter-transaction association rules are able to deduce the interactions between genes from time series microarray data and the gene expression status can be predicted based on the association rules.

0.05). Conclusions Our study does not support a positive association between Chlamydia pneumoniae infection or reinfection and MS. Chlamydia pneumoniae may be a bystander pathogen.

Objective To explore the effect of minimally invasive transpedicular bone grafting additional ver -tebral pedicle screw fixation in the treatment of thoracolumbar fracture .Methods 60 patients with thoracolumbar fracture were randomly divided into the observation group and the control group ,30 cases in each group .The control group received traditional open inter vertebral four nail pedicle screw fixation combined with posterolateral bone graft fusion for treatment while the observation group was treated by minimally invasive transpedicular bone grafting addi -tional vertebral pedicle screw fixation ,to analyze the clinical effects .Results The imaging parameters of postopera-tion[the sagittal index(1.9 ±7.1)°,Cobb's angle(4.2 ±3.5)°,change of vertebral body height (90.2 ±6.5)%]in the observation group were significantly better than those of the control group (t=6.78,6.80,7.02,all P<0.05). The imaging parameters 3 months after operation[the sagittal index(4.9 ±3.2)°,Cobb's angle(7.0 ±2.7)°,change of vertebral body height (87.6 ±4.1)%] in the observation group were significantly better than those of the control group(t=6.78,6.80,7.02,all P<0.05).The operation time,incision length,bleeding volume,postoperative drain-age,postoperative hospital stay of the observation group were (141.9 ±14.2)min,(10.8 ±1.7)cm,(105.7 ±12.3)mL, (5.6 ±4.1)mL,(6.6 ±1.1)d,respectively,which were significantly better than those of the control group (t=7.72,7.89,5.68,all P<0.05).Conclusion Minimally invasive transpedicular bone grafting additional vertebral pedicle screw fixation has a significant effect in the treatment of thoracolumbar fractures ,which is safe and reliable .

Objective To investigate the length of preserved ileocecum in surgical treatment of slow transit constipation ( STC) by sub-total colectomy with antiperistaltic cecorectal anastomosis .Methods A total of 82 patients with STC were divided into two groups according to the random number table method ,with 41 cases in each group ,all the patients of the two groups underwent subtotal colectomy ,intraopera-tive ileocecum was preserved length of group A was 10~15 cm,group B was 2~3 cm.The operation time,intraoperative bleeding volume, postoperative exhaust time and length of hospital stay were compared .Wexner constipation score and gastrointestinal quality of life index ,ab-dominal pain ,frequency score and emptying time of ileocecus before and after 6 months and 12 months between the two groups were com-pared.Results There was no statistically significant difference in the operation time ,intraoperative bleeding volume ,postoperative exhaust time and hospitalization time of two groups (P>0.05).Wexner constipation score,abdominal pain,frequency score of the two groups after 6 months and 12 months decreased significantly (P<0.05,P<0.01),of which the group B was lower than that of the group A (P<0.05,P<0.01). The gastrointestinal quality of life index after operation significantly increased (P<0.01),of which the group B was higher than that of the group A (P<0.01).Ileocecal emptying time of the group B 12 months after operation was shorter than that of the group A (P<0.01),the differences were statistically significant .Conclusion Subtotal colectomy with antiperistaltic cecorectal anastomosis is an effective method to treat STC,which can reduce the length of preserved ileocecum and improve the prognosis of patients .
