OBJECTIVETo evaluate clinical results of early total care (ETC) treatment for elderly patients with intertrochanteric femur fractures.

METHODSClinical data of 106 elderly patients with intertrochanteric fracture treated from January 2012 and February 2015 were retrospectively studied. According to whether receiving the early total care mode, the patients were divided into 2 groups, 34 cases were diagnosed and treated with early total care pattern (ETC group), including 14 males and 20 females with an average age of (74.88 ± 4.38) years old ranging from 70 to 86. According to Evans types, 4 cases were type I, 5 cases were type II, 13 cases were type III, 11 cases were type IV, 1 case was type V. Seventy-two patients were treated with conventional trauma method (conventional group), including 35 males and 37 females with an average age of (74.46 ± 3.63) years old ranging from 70 to 85. According to Evans type, 8 cases were type I ,13 cases were type II, 25 cases were type III, 25 cases were type IV, and 1 case was type V. All fractures were treated with proximal femoral nails anti-rotation (PFNA). Operative time, hospital stays, leaving bed time, complications, cases of death at 1 year after operation, postoperative Harris score at 12 months were observed and compared.

RESULTSAll patients were followed up, the time of ETC group ranged from 9 to 18 months with an average of 13.29 ± 1.51, and the time in conventional group ranged from 12 to 16 months with an average 12.93 ± 1.15, while there was no significant difference between two groups in time of following-up (t = 1.368, P = 0.174). There was no significant meaning in cases of death between ETC group (2 cases) and conventional group (8 cases). Three cases occurred complications in ETC group, and 20 cases in conventional group,there was obvious meaning between two groups (χ² = 0.739, P = 0.318). Operative time,hospital stays,leaving bed time in ETC group respectively was (2.03 ± 0.67) d, (15.41 ± 2.87) d and (3.62 ± 0.74) d; while in conventional group respectively was (4.17 ± 1.59) d, (20.11 ± 4.24) d and (5.35 ± 1.22) d; there were significant differences between two groups in operative time, hospital stays, leaving bed time. Postoperative Harris scores at 12 months in ETC group was (82.32 ± 4.56), and (79.24 ± 5.52) in conventional group, there was obvious meaning between two groups (t = 2.833, P = 0.006).

CONCLUSIONETC pattern is a novel method for diagnosis and treatment of intertrochanteric femur fractures in elderly, it could shorten operative time, hospital stays, leaving bed time, decrease complications and promote recovery of function.

To study whether recombinant human erythropoietin (rhEPO) reduces neuronal apoptosis through inhibiting over-expression of glyceraldehyde-3-phosphate dehydrogenase (GAPDH) in nucleus induced by brain ischemia/reperfusion in rats, 48 adult Sprague-Dawley rats were randomly divided into 3 groups: sham, saline and EPO groups. Animal models of brain ischemia/reperfusion were established by middle cerebral artery occlusion in rats. The effects of EPO on the sizes of ischemia tissue were observed by TTC staining. The over-expression of GAPDH in nucleus was detected by Hoechst-33258 and anti-GAPDH antibody double staining. The neuronal apoptosis in penumbral was detected by Nissl's staining and Hoechst-33258 immunofluorescence, respectively. The results showed that rhEPO treatment (3 000 U/kg, three times daily, i.p.) apparently reduced the sizes of infarct brain tissue in ischemia/reperfusion rats. rhEPO inhibited over-expression of GAPDH in nucleus of apoptotic neurons. In the meantime rhEPO decreased the number of apoptotic neurons in ischemia/reperfusion rats. These results suggest that rhEPO may induced reduction of neuronal apoptosis in penumbra may be through inhibiting over-expression of GAPDH in nucleus of apoptotic neurons induced by ischemia/reperfusion. Reduction of GAPDH over-expression in nucleus may play a pivotal role in EPO inhibiting neuronal apoptosis in cerebral ischemia/reperfusion rats, providing experimental evidence for EPO neuro-protecting effects against ischemia/reperfusion.

OBJECTIVE: To compare the anesthesia properities of hyperbaric bupivacaine with those of isobaric and hypobaric solutions when administered in the supine position undergoing hip surgery or lower limb surgery using continuous spinal anesthesia. METHODS: Sixty patients( ASA I approximately III ) scheduled for hip or lower limb surgery were randomly divided into 3 groups with 20 patients in each group: Group A: 0. 375% hyperbaric bupivacaine solutions; Group B :0.375% isobaric bupivacaine solutions; and Group C: 0. 375% hypobaric bupivacaine solutions. The following variables were measured every 2 minutes during the first 30 minutes after the intrathecal injection : the onset time of sensation block, the highest plane of analgesia, the time to reach complete motor blockade, and the plane of analgesia and the extent of lower extremities' movement (modified bromage score, BMS) at different time after the administration. Meanwhile the changes of hemodynamics were recorded. RESULTS: There was no statistical difference among the basic conditions ( P > 0.05). The onset time of sensation block, and the time to reach complete motor blockade, and the time receiving the highest sharp pain sensory block in Group A were significantly shorter than those in Group B and Group C ( P < 0.01 ). The plane of analgesia obtained in the hyperbaric group was significantly higher than in both the isobaric and the hypobaric groups ( P < 0.01). The mean arterial pressure(MAP) , HR in the hyperbaric group decreased significantly after the intrathecal injection( P < 0.05 ). CONCLUSION The 0.375% Isobaric bupivacaine used during contiuous spinal anesthesia in the supine position produces a suitable and a more "controllable" anesthesia, but a minimum dosage of 10 approximately 12.5 mg is required to obtain adequate anesthesic conditions with moderate hemodynamic changes and satisfying analgesia effects. Under similar conditions, 0. 375% hyperbaric bupivacaine produces major hemodynamic consequences with high cephalad spread and 0. 375% hypobaric bupivacaine has a too long onset time.

OBJECTIVETo observe the effect of transcutaneous electrical acupoint stimulation (TEAS) on nausea and vomiting (N&V) induced by patient controlled intravenous analgesia (PCIA) with Tramadol.

METHODSSixty patients who were ready to receive scheduled operation for tumor in the head-neck region and post-operation PCIA, aged 39-65 years, with the physique grades I-II of ASA, were randomized into two groups, A and B, 30 in each group. The pre-operation medication, induction of analgesia and continuous anesthesia used in the two groups were the same. TEAS on bilateral Hegu (LI4) and Neiguan (PC6) points was intermittently applied to the patients in group A starting from 30 min before analgesia induction to 24 h after operation, and the incidence and score of nausea and vomiting, antiemetic used, visual analogue scores (VAS), and PCIA pressing times in 4 time segments (0-4, 4-8, 8-12 and 12-24 h after the operation was finished) were determined. The same management was applied to patients in Group B, with sham TEAS for control.

RESULTSThe incidence and degree of N&V, as well as the number of patients who needed remedial antiemetic in Group A were less than those in Group B. The VAS score and PCIA pressing time were lower in Group A than those in Group B in the corresponding time segments respectively.

CONCLUSIONTEAS could prevent N&V induced by PCIA with Tramadol.

Using total DNA isolated from Amaranthus caudatus as the template, a DNA fragment of about 700bp upstream of the coding sequence of Amaranthus caudatus agglutinin (ACA) gene was amplified by TAIL-PCR and cloned. To examine the regulatory function of this DNA fragment, it was inserted into a plant expression vector containing GUS gene to substitute the CaMV 35S promoter and the resulted recombinant plasmid was designated as pBpAG. The expression vector pBpAG was transferred to different tissues of plants, via Agrobacterium-mediated transformation in vacuum condition. Transient expression of GUS in the transformed tissues was detected by histochemical GUS staining and the results showed that the GUS activity was expressed specifically in seeds. These preliminary results indicate that this DNA fragment upstream of the ACA coding sequence could very possibly be a promoter with seed specificity. Some putative cis-elements within the promoter were discussed.

The commonly used plant constitutive expression vector pBI121 was modified by insertion of two directly orientated lox sites each at one end of the selectable marker gene NPTII and by replacing the GUS gene with a sequence composed of multiple cloning sites (MCS). The resulting plant expression vector pBI121-lox-MCS is widely usable to accommodate various target genes through the MCS, and more importantly to allow the NPTII gene removed from transformed plants upon the action of the Cre recombinase. In addition, the CaMV 35S promoter located upstream of the MCS can be substituted with any other promoters to form plant vectors with expression features specified by the introduced promoters. Provided in this paper is an example that an enhanced phloem-specific promoter of the pumpkin PP2 gene (named dENP) was used to construct an NPTII-removable phloem-specific expression vector pBdENP-lox-MCS. Moreover, to facilitate screening of selectable marker-removed gene and the composite sequence is flanked by lox sites. Thus the selectable marker-free plants can be visually identified by loss of GFP fluorescence. The above newly created plant expression vectors can be used to develop selectable marker-removable transgenic plants for a variety of purposes.

BACKGROUNDAlthough heart transplantation has become a standard therapy for end-stage heart disease, there are few published studies regarding the use of transplant organs from marginal donors. Here we describe the clinical outcome we have obtained using marginal donor hearts.

METHODSWe analyzed 21 cases of orthotopic heart transplantation for end-stage heart disease performed in our department between September 2008 and July 2010. Of these patients, six received hearts from marginal donors and the remainder received standard-donor hearts. The two groups were compared in terms of both mortality and the incidence of perioperative complications such as infection, acute rejection, and right heart insufficiency.

RESULTSThe 1-year survival rate of both groups was 100%. Only one death was recorded in standard-donor group during follow-up. Patients who received marginal donor hearts (83%) experienced more early complications than did the standard-donor-heart group (13%), but the mortality of the two groups was the same. The duration of post-ICU stay was greater in the marginal donor group than in the standard-donor group, (35.5 ± 17.4) days and (21.7 ± 2.6) days, respectively (P < 0.05).

CONCLUSIONSThe use of marginal donor hearts increases the number of patients who can receive and benefit from transplants. However, it may introduce an increased risk of early complications, thus care should be taken both in the choice of patients who will receive marginal donor hearts and in the perioperative treatment of those for whom the procedure is performed.
