Objective To observe any change in the laterality index (LI) in the active volume of the hand motor cortex during rehabilitation after acute cerebral infarction and to analyze the mechanisms involved in the rehabilitation of motor function.Methods Sixteen patients with acute cerebral infarcts were administered standard but individualized rehabilitation training.Blood oxygenation-dependent functional magnetic resonance imaging (BOLD-fMRI) was used to evaluate the active volume of their hand sensorimotor cortex (SMC) and the LI,at admission and after 14 days of rehabilitation.The Fugl-Meyer motor assessment for the hand (FMA) was used to evaluate hand function.Ten healthy volunteers were recruited as a control group and subjected to a single BOLD-fMRI examination to confirm the location and the volume of the active area when performing the same rehabilitation exercises.Results The baseline LI of affected hand SMC activation was significantly smaller than that of the unaffected hand [(0.010 ±0.808) versus (0.789 ± 0.157)],but no significant difference was observed between the affected and the unaffected hands after treatment.Rehabilitation therapy significantly increased the SMC LI of affected hand activation when compared with the baseline,but no such effect was observed with the unaffected hand.In 12 patients with dysfunction of the right hand as evaluated by the FMA,the baseline LI of the affected hand was smaller than that of the unaffected hand and that of the healthy volunteers.Conclusion Rehabilitation after acute infarction can promote functional recovery.The LI of the affected hand reflects cerebral plasticity during rehabilitation after acute cerebral infarction.

BACKGROUND:Recently, the number of elder patients with femoral neck fracture increased. It is controversial if patients aged over 75 years should receive total hip replacement or hemiarthroplasty. To select a reasonable surgical manner is of great significance for increasing surgical safety, improving hip joint function, elevating quality of life, decreasing postoperative complications, and reducing revision rate.
OBJECTIVE:To retrospectively analyze data of patients aged over 75 years after hip replacement, to compare the advantages and disadvantages, and to find a precise indication.
METHODS:Case data of 171 patients undergoing total hip replacement (observation group) (n=51) or hemiarthroplasty (control group) (n=120) were included. Their differences were compared using basic diseases, operation time, bleeding amount, postoperative complications, postoperative hospitalization day, Harris score at 1 week and 3 months after operation.
RESULTS AND CONCLUSION:Patients in both groups were fol owed up for 3 to 39 months (averagely 23 months). No significant difference in basic diseases, average age, postoperative complications, postoperative hospitalization day, and Harris score at 1 week was detected between the two groups (P>0.05). Harris score and excellent and good rate at 3 months were better in the total hip replacement group than that in the hemiarthroplasty group (P<0.05). Results indicated that strict choice of indication achieved good short-period efficiency in two groups. Thus, hip function of elder patients was early recovered. Quality of life was obviously elevated. The recovery of hip function was relatively better at 3 months in observation group. The incidence of postoperative complications did not increase obviously. These results suggested that besides sufficient preparation, total hip replacement should be the first choice for elder patients.

We describe a 44-year old man who suffered an isolated external auditory canal granulocytic sarcoma in remission of acute myeloid leukemia. The patient confirmed acute promyelocytic leukemia three years ago and the disease was in remission after treatment. Two months ago he presented pain and hearing loss in the left ear and the symptom developed gradually. At otoscopic examination a tumoral lesion was noted in the external auditory canal and computerized tomography scan showed a mass in the left external acoustic meatus without bone erosion.

BACKGROUND: Angiogenesis in atherosclerotic plaque occurred on the basis of atherosclerotic lesions, and the new formed blood vessels promoted the development of angiogenesis. Soluble vascular endothelial growth factor receptor 1 (sFlt-1) gene transfection reduces neointimal formation after vascular injury in rabbits, also reduces early vascular inflammation and proliferation, and the formation of neointima lately.
OBJECTIVE: To observe the effects of highly expressed sFlt-1 on atherosclerotic plaque.
METHODS: A total of 48 male New Zealand rabbits were divided into four groups randomly: normal control group (n=8), sham operation group (n=8), bal oon injury+high lipid diet+pEGFP-N1 group (n=16) and bal oon injury+high lipid diet+pEGFP-N1-sFlt-1 group (n=16). Normal control group and sham operation group were supplied with normal diet. Bal oon injury+high lipid diet+pEGFP-N1 group and bal oon injury+high lipid diet+pEGFP-N1-sFlt-1 group were supplied with high lipid diet and injured by bal oon 2 weeks later. Bal oon injury+high lipid diet+pEGFP-N1 group was transfected with pEGFP-N1 and bal oon injury+high lipid diet+pEGFP-N1-sFlt-1 group was transfected with pEGFP-N1-sFlt-1.
RESULTS AND CONCLUSION: In the bal oon injury+high lipid diet+pEGFP-N1 group and bal oon injury+high lipid diet+pEGFP-N1-sFlt-1 group, blood lipid levels apparently increased. At 3 days after model establishment, sFlt-1 expression levels noticeably increased, and atherosclerotic plaque formed to different degrees. Plaque area, plaque perimeter, plaque maximum thickness and the number of positive-cel s within the plaque were significantly less in the bal oon injury+high lipid diet+pEGFP-N1-sFlt-1 group than in the bal oon injury+high lipid diet+pEGFP-N1 group. These results confirm that sFlt-1 gene may express effectively in iliac artery wal of rabbit, inhibited the formation of atherosclerotic plaque and delayed the development of atherosclerotic plaque.

Objective To observe the outcome of the implementation of personalized enteral nutrition of severe acute pancreatitis patients. Methods 24 patients with severe acute pancreatitis admitted from June 1, 2013 to March 31, 2014 were divided into experimental group and control group according to the random number table method. Control group calculated the energy supply according to the basic energy expend formula while experimental group according to the actual enery expend formula. Hemoglobin, albumin, C-reactive protein, serum and urine amylase, complication rate, hospitalization time and cost changes were compared. Results 7 days after enteral nutrition, hemoglobin content and albumin content of experimental group were higher than those of control group [(130.50±17.60) g/L vs.(126.33±23.96) g/L, t=-4.231, P<0.05; (40.88±4.66) g/L vs.(36.29±3.45) g/L, t=-2.263, P<0.05]. And C-reactive protein of experimental group were lower than that of control group [(47.62±9.89) mg/L vs.(58.22±11.23) mg/L, t=3.618, P<0.05]. Hospitalization time and cost of experimental group were lower than those of control group [(22.50±5.85) d vs.(16.75±6.47) d, t=12.272, P<0.01; (36 364.76±2 162.08) yuan vs.(14 143.44±3 921.78) yuan, t=9.421, P<0.01]. Conclusions The implementation of personalized enteral nutrition is more hepful for the physiological requirements of individual patients, and not affect the pancreatic secretion. At the same time, inflammatory mediators can be reduced and also reduce the economic burden of patients and society.

CONCLUSIONS:The establishment of talent training mode for pharmaceutical specialty in retail pharmacies based on mod-ern apprenticeship can improve the teaching quality of pharmacy major in vocational colleges. However,the establishment of course system should consider the sustainable development of students,and cautiously set targeted courses based on the characteris-tics of talents requirements in retail pharmacies.

Objective To study the changes in pulmonary diffusing capacity (DL), alveolar capillary membrane diffusing capacity (Dm) and pulmonary capillary blood volume (Vc) in patients with severe acute respiratory syndrome (SARS), and to elucidate the underlying pathophysiogical mechanism of reduction of pulmonary diffusing capacity. Method Spirometry was performed in 26 SARS patients and 12 healthy individuals in resting condition. DLco were measured by single breath method, estimations of Dm and Vc were done by the method of Roughton and Forster. Results DLco in SARS patients was significantly lower than that in normal control, the same was true for Dm and Vc. The severer the pulmonary lesion, the heavier the damage to the pulmonary diffusing funetion. Conclusion The changes in Dm and Vc were both found in patients with SARS. Their measurements were helpful for detecting pulmonary involvement in SARS and defining the reason of DL abnormality in SARS. Dm and Vc were important and sensitive for monitoring pulmonary diffusing function in SARS patients
