ABSTRACT

Objective:To observed the effects of electroacupuncture frequency on the nerve function and postsynaptic destination-95 (PSD-95), growth associated protein-43 (GAP-43) in brain tissue of rats with cerebral ischemia were observed.Methods:Healthy adult male SD rats were randomly divided into the blank group, sham operation group, model group and 2 Hz, 50 Hz, 100 Hz electroacupuncture groups. MCAO models were prepared in each group, except blank group and sham operation group. After modeling, Qiansanli and Waiguan acupoints were given stimulation with 2 Hz, 50 Hz and 100 Hz respectively in 2 Hz electroacupuncture group, 50 Hz electroacupuncture group and 100 Hz electroacupuncture group, 1 time/d and 20 min/time for 21 consecutive days. All groups were scored by Bederson score on the 1st, 3rd, 7th, 14th and 21th day after operation. The ultrastructure of synapses was observed by transmission electron microscope, and the positive expression of PSD-95 and GAP-43 was detected by immunohistochemistry. Results:After modeling 7, 14 and 21 days, compared with the model group, the Bederson behavioral score (1.70 ± 0.52 vs. 2.40 ± 0.56, 1.20 ± 0.65 vs. 2.30 ± 0.46, 0.70 ± 0.72 vs. 2.00 ± 0.86) in 50 Hz electroacupuncture group significantly decreased ( P<0.01 or P<0.05). The expression of PSD-95 (58.67 ± 1.72, 55.22 ± 2.45, 60.10 ± 2.49 vs. 70.87 ± 2.34) intergral optical density of rats’ cortex in 2 Hz, 50 Hz, 100 Hz electroacupuncture groups significantly decreased ( P<0.01), the expression of GAP-43 in 2 Hz and 50 Hz electroacupuncture groups (58.89 ± 1.28, 64.76 ± 3.94 vs. 53.24 ± 2.58) significantly increased ( P<0.01). Conclusions:Electroacupuncture with different frequency can improve motor nerve disfunction of cerebral ischemia rats, and 50 Hz electroacupuncture group showed the most obvious effect. It can regulate PSD-95 and GAP-43 expressions of ischemic area, lower neural excitatory toxicity, increase neuronal axon regeneration and exert the neural protect function.

ABSTRACT

Objective@#To analyze the imaging characteristics and diagnostic value of 18F-fluorodeoxyglucose (FDG) PET/CT in muscular inflammation in dermatomyositis (DM), as well as the relationship between maximum standardized uptake value (SUVmax) and activity of muscular inflammation.@*Methods@#From July 2013 to November 2016, 17 hospitalized DM patients (8 males, 9 females, age range: 35-78 years) who underwent 18F-FDG PET/CT were retrospectively reviewed, including 13 typical DM (TDM) and 4 amyopathic DM (ADM). Seventeen healthy volunteers (8 males, 9 females, age range: 35-78 years) in the same period were enrolled as the control group. The proximal limb muscles of whole body were divided into 7 areas, and the SUVmax of each was measured and recorded. Two-sample t test, one-way analysis of variance, Dunnett-t test and Spearman correlation analysis were used to analyze data.@*Results@#Five TDM cases showed diffuse increased FDG uptake in global muscles; 8 TDM cases showed increased FDG uptake in local muscles, mainly in the shoulder and hip. The FDG uptake by muscles of 4 ADM patients was similar with that of controls. The SUVmax was lower and lower in the order of shoulder and back muscles, hip muscles, thoracic vertebra muscles, cervical vertebra muscles, biceps, proximal quadriceps and lumbar vertebra muscles in DM group. The muscle SUVmax of DM, TDM, ADM and the controls were 1.92±0.86, 2.14±0.85, 1.19±0.44 and 0.93±0.26, respectively (F=69.50, P<0.001). Muscle SUVmax of DM group was higher than that of controls, muscle SUVmax of TDM was higher than that of ADM, and muscle SUVmax of ADM was higher than that of controls (t values: 4.102-11.970, all P<0.05). Muscle SUVmax of 9 DM patients with interstitial lung disease (ILD) was lower than that of patients without ILD (1.73±0.09 vs 2.13±0.13; t=5.857, P<0.001). Muscle SUVmax of DM was positive correlated with serum levels of creatine kinase (CK) and creatine kinase isoenzyme composed by M and B subunits (CK-MB) (rs values: 0.814 and 0.751, both P<0.001).@*Conclusion@#18F-FDG PET/CT is helpful to detect muscular inflammation of DM and it can reflect the activity and severity with SUVmax, and meanwhile evaluate the condition of ILD associated with DM.

ABSTRACT

Objective To investigate the effect of acupuncture point injection and rehabilitation on the functional recovery of upper limbs and daily living ability of shoulder-hard syndrom (SHS) after cerebral hemorrhage. Methods A total of 96 patients SHS after cerebral hemorrhage were divided into the observation group (n=56) and the control group (n=40). Both groups recieved the routine treatment for cerebral hemorrhage and rehabilitation technique training. Besides, the control group was treated with intermediate frequency physiotherapy, and the observation group was treated with electroacupuncture and acupoint injection of Salvia miltiorrhiza and ligustrazine. After 1 months of treatment, the the upper limb movement function, daily living ability (ADL), shoulder joint pain, joint activity degree, and the degree of joint swelling were evaluated and compared. Results After treatment, the FMA (60.1 ± 6.4 vs. 41.8 ± 18.7, t=6.799), MBI (65.2 ± 3.5 vs. 50.6 ± 2.1, t=23.512) scores of the observation group were significantly higher than those of the control group. The VAS (2.7 ± 1.4 vs. 4.9 ± 1.3, t=7.817), edema volume (2.1 ± 2.1 cm3 vs. 2.1 ± 2.1 cm3, t=7.316) of the observation group were significantly lower than those of the control group ( P<0.01). The anterior flexion (163.1 ± 6.7°vs. 56 ± 10.9°, t=59.516), extension (39.6 ± 5.8°vs. 23.2 ± 6.7°, t=12.799), abduction (168.1 ± 9.6°vs. 52.1 ± 8.9°, t=60.148), adduction (52.1 ± 3.6°vs. 29.8 ± 4.3°, t=27.580), external rotation (49.8 ± 7.6°vs. 23.2 ± 5.2°, t=19.151), internal rotation (107.0 ± 8.5°vs. 60.2 ± 6.1°, t=29.758) of the observation group were significantly higher than those of the control group (P<0.01). The total effective rate of the observation group was 91.1% (52/56) and the control group was 70% (28/40), and the difference between the 2 groups was statistically significant (χ2=7.209, P<0.01). Conclusions Acupuncture combined with acupoint injection and rehabilitation technology can relieve pain, eliminate edema and improve motor function and daily living ability of SHS patients after intracerebral hemorrhage.

ABSTRACT

[Objective] Examine the expression of Galectin-3 (Gal-3),B cell lymphoma-2 protein (Bcl-2) in epithelial ovarian cancer tissues with regard to clinicopathological and survival variables,testing whether they can serve as prognostic markers and provide evidence for further research.[Methods] 98 EOC tissues and 10 normal ovarian tissues were collected,as well as their clinical documents.The expression of Gal-3 and Bcl-2 was tested via immunohistochemical staining analysis.Then the correlation between these two proteins and the clinicopathological and survival variables of these patients were evaluated.[Results] Of the 98 EOC,Gal-3 and Bcl-2 were all cytoplasmic staining.Gal-3 was observed in a majority of the EOC tumor cell proper (75/98,76.5%) but not in normal ovarian tissues.Bcl-2 was observed in a majority of the EOC tumor cell proper (50/98,51.0%) but not in normal ovarian tissue.Spearman bivariate correlation test show that there was no correlation between the expression Gal-3 and Bcl-2 (P =0.867).Gal-3 expression in EOC was associated with histology and platinum sensitivity (P =0.043,P =0.038),while Bcl-2 was associated with FIGO stage (P =0.029).Cox univariate analysis revealed that Gal-3,Bcl-2 expression,platinum sensitivity,stage were associated with overall survival (P =0.008,P =0.021,P < 0.001,P < 0.001).Further multivariate analysis showed that only Gal-3 expression,platinum sensitivity,stage affected the survival of these patients (P =0.014,P =0.021,P < 0.001).[Conclusions]The expression of Gal-3 and Bcl-2 in EOC was significantly higher than that in normal ovarian tissue,supposed that they may involve in the development and progression of EOC.Gal-3 expression was associated with histology,platinum sensitivity and survival,it may be an independent predictive factor for EOC prognosis.There was no correlation between the expression Gal-3 and Bcl-2 in EOC,the functional mechanism between these two protein need further research.

ABSTRACT

Objective To explore the effects of improvements on setup error ( SE ) and clinical target ( CTV ) margin of supraclavicular field ( SCF ) by using moisture-cured resin cushion and breast bracket for lower neck fixation in breast cancer patients who underwent post-mastectomy radiotherapy. Methods Totally 13 patients with breast cancer who underwent post-mastectomy radiotherapy were enrolled. All patients were immobilized by breast bracket and moisture-cured resin cushion. Firstly, each patient′s lower neck and head was fixed well by moisture-cured resin cushion, filling the gap between the neck and breast bracket. Secondly,each patient underwent the cone-beam CT ( CBCT) at the first, tenth and twentieth treatment after positioning. Then these CBCT images were registered to the planning CT to determine setup errors in translational and rotational directions, and SCF CTV margins by the systematic and random errors were evaluated. Results The setup errors in x (left-right), y (superior-inferior), z (anterior-posterior) translational directions were (2. 16 ± 1. 25), (1. 50 ± 1. 28), (1. 94 ± 1. 12) mm and (1. 76 ±1. 87)°, (1. 82 ±1. 12)°, (0. 99 ±0. 58)°, respectively in θ (pitch degree),Ф(roll degree),ψ( yaw degree) rotational directions. Non-parametric rank test ( Mann-Whitney U test) was performed with previous data, the differences of the setup error in y, z,θ directions were statistically significant ( Z =4. 152, 3. 415, 2. 053, P<0. 05). The margins from CTV were 4. 07, 4. 03 and 3. 73 mm in x, y and z directions, respectively. Compared with the previous study on SCF, CTV margin required 8, 8 and 6 mm in x, y and z axis directions, the volume of CTV to PTV were decreased by 32. 73% on average. Conclusions Compared with plastic circular pillow alone, moisture-cured resin cushion with breast bracket locating method could reduce setup errors in SCF target region. The margins from CTV to PTV weredecreased to 4. 07, 4. 03 and 3. 73 mm in x, y and z axis directions at least.

ABSTRACT

We analyzed the genetic characteristics of coxsackievirus A4 (CV-A4) based on the entire VP1 coding region. Samples were isolated from patients with acute flaccid paralysis (AFP) in Shaanxi, China from 2006 to 2010. We wished to ascertain the predominant genotype and the relationship between CV-A4 infection and AFP. Sixty-eight non-polio enteroviruses were inoculated onto RD cells (to increase the virus titer) and molecular typing was undertaken. The entire VP1 coding region was amplified. Percentage of CV-A4 was 10.3% (7/68). Analyses of genetic identify and creation of phylogenetic trees revealed that CV-A4 could be classified into A, B and C genotypes. Seven CV-A4 strains from Shaanxi and other CV-A4 strains from China formed an independent evolution lineage located in group 4 and belonged to the C2 sub-genotype. These data suggested that CV-A4 strains of sub-genotype C2 were the predominant genotypes in China. These strains co-evolved and co-circulated with those from other provinces in China, so continued monitoring of CV-A4 (by clinical and genetic surveillance) should be enhanced.

ABSTRACT

BACKGROUND:Primary culture in vitro of neurons plays an important role in the development, regeneration, signal transduction mechanisms, neuropharmacology and gene expressions of the nervous system. OBJECTIVE:To establish a simple method for primary culture of high-purity cortical neurons in neonatal Sprague-Dawley rats. METHODS:Cortical tissues were acquired from neonatal Sprague-Dawley rats born 1 day. In traditional experimental group, the whole cortex was removed;in improved experimental group, the cortical tissues, 2-3 mm thick on the brain surface were removed. Single cel suspensions were prepared after papain digestion and centrifugation and were then seeded onto 24-wel culture plates containing neuron solutions for primary culture (1×105 per wel ). Cel s were identified by neuronal specific markers MAP-2 and Tuj1 after 3-day culture. The number of neurons and neurite length were observed under inverted phase contrast microscope and recorded at 6, 24, 48 and 72 hours, 5 and 7 days of culture, resprctively. RESULTS AND CONCLUSION:The cultured cel s expressing MAP-2 and Tuj1 were neurons that could be used in the fol owing experiments. The purity of neurons in the improved experimental group was 92%at 3 days, while only 51%in the traditional experimental group. Cel s in both two groups had attached to the wal presenting with smal processes at 6 hours, and a simple neural network formed at the 3rd day until dense neural networks could be found at the 5th day. To conclude, our culture method herein is simple and convenient, and can be used to produce neurons with high purity, which wil be helpful for the experimental studies on cortical neurons from Sprague-Dawley rats.

ABSTRACT

ObjectiveTo investigate the effect of acup point injection and rehabilitation techniques on recovery of upper limb function and activities of daily life (ADL) in patients with shoulder-hand syndrome (SHS) after cerebral infarction.Methods Ninety-six patients with SHS after cerebral infarction admitted to Jiuquan City Traditional Chinese Medicine Hospital and Jiuquan City People's Hospital from January 2014 to February 2016 were enrolled, and they were randomly assigned to observation group (56 cases) and control group (40 cases). The patients in the two groups were given the same routine comprehensive cerebral infarction treatments and rehabilitation technological training. In the control group, additionally intermediate frequency physiotherapy was used, while in the observation group, acupuncture and acupoint injection of salvia miltiorrhiza and ligustrazine were added. The patients in two groups were treated consecutively for one month, afterwards, the upper limb motor function, ADL, shoulder joint pain, degree of swelling and range of motion were assessed, and the clinical effects were observed.Results After treatment, the modified Fugl-Meyer motor function score (FMA), modified barthel index (MBI) and the ranges of voluntary activities of shoulder abduction, adduction, flexion, extension, internal rotation and external rotation in patients of two groups were significantly increased than those before treatment; the pain visual analog scale (VAS) and the edema volume difference in observation group were lower than those in the control group, and after treatment, the changes of above indexes were more significant in the observation group than those in the control group [FMA: 70.10±6.38 vs. 41.76±18.69, VAS: 2.00±1.37 vs. 5.00±1.25, MBI: 75.17±3.51 vs. 51.56±2.12, edema volume difference (cm3): 2.13±2.05 vs. 5.75±1.17, flexion: (153.1±6.7)° vs. (56.0±10.9)°, extension: (39.6±5.8)° vs. (17.2±6.7)°, abduction:(168.1±9.6)° vs. (52.1±8.9)°, adduction: (52.1±3.6)° vs. (21.8±4.3)°, external rotation: (49.8±7.6)° vs. (23.2±5.2)°, internal rotation: (107.0±8.5)° vs. (51.2±6.1)°], the total effect in observation group was significantly higher than that in the control group [91.1% (52/56) vs. 70.0% (28/40),P < 0.05].Conclusions Acupuncture and acupoint injection combined with three-level therapeutic regimen of rehabilitation technological training for treatment of shoulder-hand syndrome after cerebral infarction can reduce the patient's pain and edema, and improve upper limb motor function and activities of daily living.

ABSTRACT

Objective To investigate the characteristics of 18F-FDG PET/CT imaging in Takayasu arteritis (TA) and its clinical value.Methods Five male patients with TA in active phase (age range:65-82 years;mean age:(72.8±6.6) years) from November 2011 to August 2014 were retrospectively analyzed.All patients underwent 18F-FDG PET/CT imaging,and one of them who was in stable phase after one year's treatment underwent follow-up PET/CT imaging.The characteristics of the abnormal 18F-FDG uptake and SUVmax of lesions were analyzed.Another 5 age-and gender-matched patients with slightly elevated tumor markers and normal results of 18F-FDG PET/CT imaging in the same period were selected as the control group.Arteries were divided into 18 segments,including the ascending aorta,the aortic arch,the descending aorta,the abdominal aorta,the brachiocephalic trunk,the left/right common carotid,the left/right subclavian,the left/right brachial,the superior mesenteric,the left/right common iliac,the left/right renal,and the left/right femoral,and their SUVmax were measured respectively.Paired t test was used to analyze the difference of SUVmax between TA group and the control group.Results (1) 18 F-FDG PET/CT imaging displayed diffused increase of radioactivity in the wall of aorta and its major branches in TA group,and CT showed multiple irregular thickening,punctate and banding calcification in arterial walls of those patients.The ascending aorta,the aortic arch,the descending aorta,the abdominal aorta,the brachiocephalic trunk,the left/right subclavian,the left/right common carotid,and the left/right common iliac artery were all involved in 5 patients;the left/right brachial and the left/right femoral artery were involved in 4 patients and the superior mesenteric artery was involved in 2 cases.The SUVmax range was 1.4-7.6,the highest SUVmax was in the left subclavian artery (n=2),the right subclavian artery (n=1) and the abdominal aorta artery (n=2).(2)The SUVmax of TA group and the control group were 3.96±1.35 and 2.13±0.53,respectively(t=10.40,P<0.001).(3) As to the TA patient in stable phase after treatment,the FDG uptake of the wall of aorta and its major branches decreased obviously compared with that before treatment.The SUVmax of left subclavian artery decreased from 6.8 to 3.2.Conclusions 18F-FDG PET/CT is helpful in diagnosis of TA.It could accurately display the range of involved arteries,reflect the activity of the lesion and evaluate the therapeutic response.

ABSTRACT

The World Health Organization redefined the type 2 vaccine-derived poliovirus (VDPV) in 2010. To study the genetic characteristics and evolution of type 2 VDPV under this new definition, we conducted genome sequencing and analyses of type 2 VDPVs isolated from one patient with acute flaccid paralysis in Shanxi province (China) in 2014. Nucleotide sequencing revealed that the full-length of type 2 VDPV is 7439 bases encoding 2207 amino acids with no insertion or deletion of nucleotides compared with Sabin2. One nucleotide substitution identified as a key determinant of the attenuated phenotype of the Sabin 2 strain (A-G reversion at nucleotide nt 481 in the 5-end of the untranslated region) had reverted in the Shanxi type 2 VDPV. The other known key determinant of the attenuated phenotype of the Sabin 2 strain (U-->C reversion at nt2909 in the VP1 coding region that caused a Ile143Thr substitution in VP1) had not reverted in the Shanxi VDPV. The Shanxi type 2 VDPV was S2/S1 recombinant, the crossover site of which mapped to the 3-end of the 3D region (between nt 6247 and nt 6281). A phylogentic tree based on the VP1 coding region showed that evolution of the Shanxi type 2 VDPV was independent of other type 2 VDPVs detected worldwide. We estimated that the strain circulated for approximately = 11 months in the population according to the known evolution rate. The present study confirmed that the Chinese Polio Laboratory Network could discover the VDPV promptly and that it played an important part in maintenance of a polio-free China.

ABSTRACT

To investigate the effects of gambognic acid (GA) on TRAIL-induced apoptosis of cancer cells, human colon HT-29 cancer cells were treated with GA to promote apoptosis. Inhibition of the cell proliferation was measured with MTT assay and cell apoptosis was detected with formation of DNA ladders in agarose gel electrophoresis, and activation of caspase activity. The content of cytosolic reactive oxygen species (ROS) was measured with flow cytometry. The activities of Caspase-3, -8, -9 were detected using spectrophotometric assay. The levels of c-FLIP, CHOP, DR4 and DR5 in cells were tested by Western blot. Combination of GA (1 µg · mL(-1)) and TRAIL (40 ng · mL(-1)) significantly reduced proliferation and increased apoptosis of HT-29 cells over those induced by each agent alone. Percentage of apoptotic cells was increased to 45.5%. GA markedly enhanced the intracellular ROS generation. Expression of CHOP, DR4 and DR5 was up-regulated to 7.38, 5.41, and 4.85 times of the control group, respectively. GA promoted activation of Caspase-3, -8, and -9 by TRAIL (P<0.05). Furthermore, the expression of anti-apoptotic protein c-FLIP was down-regulated to 0.22 ± 0.08 times of the control group. In conclusion, GA sensitizes HT-29 cells to TRAIL-induced apoptosis by promoting ROS-activated ERS pathways, up-regulating of DR4 and DR5, and inhibiting c-FLIP expression.
