Objective To observe the clinical efficacy of auricular point sticking plus basic nursing for constipation of excessive syndrome in acute stage of stroke.Method Ninety patients with constipation of excessive syndrome in acute stage of stroke were randomized into a treatment group and a control group, 45 cases in each group. The treatment group was intervened by auricular point sticking plus basic nursing, while the control group was by basic nursing alone. The major symptom scores were observed before intervention and after 2-treatment courses, and the clinical efficacies were compared between the two groups.Result Respectively after 1 and 2 treatment courses, there were significant differences in comparing the major symptom scores between the two groups (P<0.05). The total effective rates were respectively 60.0% and 67.5% in the treatment group respectively after 1 and 2 treatment courses, versus 37.5% and 45.0% in the control group, and the differences were statistically significant (P<0.05). Conclusion Auricular point sticking is an effective approach in treating constipation of excessive syndrome in acute stage of stroke.

Objective To study the effect of salidroside (Sal) on learning and memory abilities and expression of p75NTR signal transducers and Aβ in AD rat hippocampus.Methods Totally,ninety-six male SD rats were randomly divided into sham-operation group,model control group,Sal low,medium and high dose group,Hup-A group (16 rats in each group).Except for sham-operation group,AD model in the other group was established by slowly injecting 1μL(10 μg)Aβ1-40 in tobilateral hippocampal CA1 area.Sham-operation group was given the same volume of 0.9% sodium chloride solution.Sal low,medium and high dose group took orally as early as 24 h postoperatively with salidroside 25,50,100 mg· kg-1 for 21days,while Hup-A group took 50 mg kg-1 of Hup-A orally.The same volume of 0.9% sodium chloride solution was administrated in shanmoperation group and model control group.After administration,the learning and memory function of rats were tested by Morris water maze.The contents of Aβ in serum and hippacampus were determined by ELISA,and protein expression of p75NTR and p-JNK in the hippocampus of the rats were measured by ELISA.Results Compared with model control group,the latent time in water maze training of Sal low,medium and high dose groups were significantly shortened (P < 0.05 or P < 0.01),the number of times of crossing platform of Sal low,medium and high dose group was significantly increased.The contents of Aβ in the hippocampus and the protein expression levels of p75NTR and p-JNK in the hippocampus of Sal low,medium and high dose group were decreased significantly (P < 0.05,P < 0.01).Conclusion Salidroside has protective effects on learning and memory consolidation of dysmnesia rats caused by Aβ.Its mechanism might be related to inhibition of p75NTR regulation pathways for Aβ,reducing the neurotoxic effect of Aβ,so as to reduce cell apoptosis of hippocampus neuron.

Objective To establish a method for detecting the concentration of paraquat (PQ) and creatinine(Cr) in urine simultaneously by capillary electrophoresis.Methods Experimental methodological study.8 acute PQ poisoned patients who were treated in the First People's Hospital of Lianyungang from January 2011 to June 2012 were collected.2 were male,and 6 were female.The separation were carried out using a 25 mmol/L pH1.97 glycine-HCl buffer(containing 40 mmol/L NaCl) in a fused-sillica capillary tube of 47 cm ×75μm I.D.by capillary zone electrophoresis.Urine had been injected by pressure for 4 s after samples were centrifuged and diluted for 10 times with H2O.The detection were monitored by a diode-array detector at 200 nm while samples were separated at a voltage of 20 kV.A systemic methodological evaluation of this method was carried out (The linear range,detection limit,repeatability test,recovery test and interference test).And the method was used to detect the concentration of PQ and Cr in PQ poisoned patients' urine.Results The peaks of PQ and Cr appeared within 5 min.The linear ranges of PQ and Cr were 2-1000,10-5000 μmol/L,respectively,with the correlation coefficients of 0.9997 and 0.9999 (P <0.01).The detection limits were 1.0 μmol/L for PQ and 5.0 μmol/L for Cr.The mean within-day(n =10) CVs of peak area for PQ and Cr were 2.84% and 1.72%,while the mean inter-day(n =10) CVs of peak area were 3.62% and 3.06%.The average recovery rate of PQ and Cr were 88.6% and 90.2% respectively.Diquat(DQ) didn't interfere with the assay.The range of PQ/Cr(μmol/mmol) for 8 cases was 8.9-2215.Conclusions A method was established successfully for the rapid determination of PQ and Cr in urine by capillary electrophoresis.The CE method devised here for direct measurement of urinary PQ and Cr from PQ poisoned patients is simple,fast,automatic and with good repeatability.It is an ideal method for rapid detection of urinary PQ in PQ poisoned patients.

Objective:To explore the clinical application of three-dimensional CT angiography (3D-CTA) in repair of limb wounds with free lateral thoracic perforator flaps.Methods:A retrospective study was conducted to analyze the clinical data of 61 patients with limb soft tissue defects who had been treated at The Third Department of Orthopedics, Xingtai General Hospital of North China Medical and Health Group from January 2018 to September 2022. There were 37 males and 24 females with an age of (43.9±12.0) years. Thirty-three left and 28 right sides were injured. Soft tissue defects ranged from 4.0 cm × 3.0 cm to 17.0 cm × 8.0 cm, and flap areas from 5.0 cm × 4.0 cm to 18.0 cm × 9.0 cm. The patients were divided into 2 groups according to the different preoperative vascular exploration methods: an ultrasound group of 30 cases subjected to ultrasound Doppler examination and a 3D-CTA group of 31 cases subjected to 3D-CTA examination. The preoperative findings were compared with those of intraoperative exploration in the 2 groups. The operation time, flap survival rate, patient satisfaction with trauma repair, sensory recovery of the flap area, and the excellent and good rate of the donor area were also compared between the 2 groups.Results:The differences in preoperative general data between the 2 groups were not statistically significant, indicating the 2 groups were comparable ( P>0.05). In the ultrasound group, the inraoperative classification of the lateral thoracic perforator flaps showed a low concordance with preoperative classification (Kappa coefficient of 0.104, P=0.088). In the 3D-CTA group, the classification of lateral thoracic perforator flaps was consistent with the preoperative 3D-CTA examination (Kappa coefficient of 1.00, P<0.001). The preoperative measurements in the 3D-CTA group found that the diameter at the origin of the lateral thoracic artery was (1.2±0.3) mm, the vascular pedicle length (8.1±2.1) cm, and the diameter at the perforator exit (0.6±0.2) mm; the preoperative surface positioning at the perforator exit found that the perforator exit was (1.6±0.3) cm above the horizontal line of the subscapular angle and (5.3±1.4) cm outside the vertical line of the subscapular angle. These measurements were similar to the intraoperative ones [(1.1±0.3) mm, (8.3±2.4) cm, (0.7±0.2) mm, (1.5±0.4) cm, and (5.2±1.5) cm], showing no significant differences ( P>0.05). In contrast, the preoperative measurements of the above indexes in the ultrasound group did not coincide with the actual intraoperative measurements, and the differences were all statistically significant ( P<0.05). The operation time, flap survival rate, rate of patient satisfaction with wound repair, rate of sensory recovery in the flap area, and the excellence and good rate of the donor area in the 3D-CTA group were (52.9±16.7) min, 100.0% (31/31), 96.8% (30/31), 83.9% (26/31), and 87.1% (27/31), respectively, which were significantly better than those in the ultrasound group [(76.3±21.4) min, 86.7% (26/30), 76.7% (23/30), 60.0% (18/30), 63.3% (20/30)] ( P<0.05). Conclusions:As preoperative 3D-CTA examination can clarify the types and anatomical characteristics of the lateral thoracic artery and its perforators, it helps the design and harvest of the lateral thoracic perforator flaps. Compared with the ultrasound Doppler examination, preoperative 3D-CTA examination shortens operation time, raises survival rate of the flaps, and facilitates recovery of the appearance and function of the limb wounds, and leads to little impact on the donor site.
