ABSTRACT

Objective:To investigate the effect of bilateral repetitive transcranial magnetic stimulation (rTMS) on the pre-attentive processing of methamphetamine addicts.Methods:Forty methamphetamine addicts were screened and equally divided into the intervention group and the control group by random number table method.The intervention group was treated with bilateral simultaneous stimulation with 10 Hz on the left DLPFC and 1 Hz on the right DLPFC with 7 days of continuous intervention.The same scheme was used to intervene the control group, but with pseudo-stimulation. The changes of amplitude and latency of mismatch negative wave(MMN) before and after intervention were compared. SPSS 24.0 software was used for statistical analysis. Independent sample t-test was used for inter group comparison, and paired sample t-test was used for intra group comparison before and after intervention. Results:Before rTMS, there were no significant differences in MMN(F3, Fz, F4) amplitude (intervention group: (-0.90±0.28)μV, (-0.98±0.19)μV, (-0.96±0.19)μV; control group: (-0.92±0.21)μV, (-0.89±0.20)μV, (-0.94±0.16)μV)and latency(intervention group: (184.16±33.07)ms, (179.20±25.35)ms, (184.95±28.22)ms; control group: (184.91±26.96)ms, (180.99±25.29)ms, (181.55±23.19)ms) between the two groups (all P>0.05). After the intervention, there were significant differences in MMN(Fz, F4) amplitude(intervention group: (-1.38±0.16)μV, (-1.17±0.19)μV; control group: (-0.91±0.17) μV, (-0.99±0.16)μV) between the two groups (both P<0.01), but there were no significant differences in MMN (F3) amplitude(intervention group: (-1.01±0.59)μV; control group: (-0.80±0.50)μV), and in MMN (F3, Fz, F4) latency(intervention group: (177.38±26.45)ms, (172.17±23.87)ms, (179.84±23.60)ms; control group: (182.08±24.95)ms, (177.94±21.30)ms, (179.18±21.62)ms)between the two groups (all P>0.05). There were statistically significant differences in MMN( Fz, F4) amplitude (before-intervention: (-0.98±0.19)μV, (-0.96±0.19)μV; after-intervention: (-1.38±0.16)μV, (-1.17±0.19)μV)before and after intervention in the intervention group (both P<0.05), but there was no significant difference in MMN(F3) amplitude(before-intervention: (-0.90±0.28)μV; after-intervention: (-1.01±0.59)μV)before and after intervention in the intervention group ( P>0.05), and there were statistically significant differences in MMN(F3, Fz, F4) latency (before-intervention: (184.16±33.07)ms, (179.20±25.35)ms, (184.95±28.22)ms; after-intervention: (177.38±26.45)ms, (172.17±23.87)ms, (179.84±23.60)ms)before and after intervention in the intervention group(all P<0.05). After pseudo-stimulation, there were no statistically significant differences in MMN( F3, Fz, F4) amplitude(before-intervention: (-0.92±0.21)μV, (-0.89±0.20)μV, (-0.94±0.16)μV; after-intervention: (-0.80±0.50)μV, (-0.91±0.17)μV, (-0.99±0.16)μV)and latency (before-intervention: (184.91±26.96)ms, (180.99±25.29)ms, (181.55±23.19)ms; after-intervention: (182.08±24.95)ms, (177.94±21.30)ms, (179.18±21.62)ms) before and after intervention in the control group (all P>0.05). Conclusion:After repeated transcranial magnetic stimulation, the pre-attentive processing of the intervention group is improved, which shows that bilateral simultaneous stimulation of the rTMS program is effective.

ABSTRACT

Objective@#Bioinformatics methods were used to annotate the suspicious pathogenic genes of congenital microtia in detail, and construct the protein-protein interaction (PPI) networks to clarify the function and interaction of pathogenic genes, so as to predict the potential pathogenic genes.@*Methods@#The pathogenic genes of congenital microtia were searched using the mouse genome informatics (MGI). The results were summarized into the STRING database to construct PPI networks. The Gene Ontology (GO) enrichment analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis were carried out.@*Results@#Sixty-eight congenital microtia-related pathogenic genes such as FGF8, EYA1 and HOXA2 were searched by MGI. The PPI network contained 65 nodes and 174 edges. The average node degree was 5.35. The clustering coefficient was 0.437 and the PPI enrichment P = 0. The key node proteins were screened in PPI networks. The top ten were CTNNB1, FGF8, EGFR, BCL2, PAX6, FGF3, FGF10, WNT5A, FGFR1 and MAPK1. GO analysis and KEGG pathway analysis showed: the pathogenic genes were involved in the biological process of ear morphogenesis, ear development and embryonic organ morphogenesis. They also get involved in the molecular regulation, including sequence-specific DNA binding and regulatory region DNA binding. Expression of different genes were located in nucleus and other sub-microscopic cell components. Pathogenic genes were also involved in cancer pathway, melanoma, MAPK signaling pathways, RAS signaling pathways and other signaling pathways.@*Conclusions@#By using bioinformatics tools, we constructed the PPI networks of the congenital microtia pathogenic genes, and obtained detailed GO enrichment and KEGG pathway data. The key nodes contained the confirmed pathogenic genes of congenital microtia, which preliminarily proved the feasibility of the bioinformatics method in this study. We found some nodes were closely linked with FGF and WNT, which may be potential mutant genes of congenital microtia, although further study is needed.

ABSTRACT

Objective@#To investigate the modification of the classic techniques of total auricle reconstruction with skin expansion, and its clinical application.@*Methods@#We performed three-dimensional measurement of the normal auricle and the expanded flap on 150 microtia patients. According to the data, we carried out total auricle reconstruction using extended postauricle expanded flap techniques for 82 patients of the group. Firstly, a 50 ml kidney-shaped expander was inserted subcutaneously in the mastoid region. Approximately 65 ml saline was injected in about 30 days, and expansion was kept without injection for another 30 days. In the second stage, we removed the expander and dissected the scalp 4-5 cm around the expanded skin, to make a composite flap consisted of expanded skin and extend scalp. Then we used the flap to encapsulate the three-dimensional rib cartilage framework to accomplish total auricle reconstruction.@*Results@#The blood supply and venous drainage of the flap was good. No obvious postoperative flap swelling was observed. Only 2 cases of helix skin necrosis happened in 48 hours after operation. Small area of skin defect was treated by debridement and suture, while larger area of skin defect was repaired with postauricular fascia flap and free skin graft. Postoperative follow-up period was 4-15 months, about 6.7 months in average. Bilateral ear size and position were similar with clear structures and shapes. Helix seemed more slim, auriculocephalic sulcus was obvious, auriculocephalic angle was similar to the other side. There was no color abberration between the front and back side of reconstructed ear. Scars of retroauricular hairline incision and costal cartilage harvesting incision were not obvious.@*Conclusions@#The novel surgical techniques is reasonable and simple without fascia flap or skin graft, which is worthy of application by more plastic surgeons.

ABSTRACT

Objective To evaluate the effects of acute peritonitis on rocuronium?induced neuromus?cular blockade in abdominal muscles and function of the sarcoplasmic reticulum of rats. Methods Thirty?six pathogen?free male Sprague?Dawley rats, weighing 220-250 g, were divided into 2 groups using a ran?dom number table: control group (group C, n=12) and acute peritonitis group (group P, n=24). After the rats were anesthetized with pentobarbital sodium, acute peritonitis was induced by artificial gastric per?foration in group P. At 1 and 2 h after operation, the changes in the intra?abdominal pressure (IAP) with different volumes were detected, and blood samples were collected from the orbital veins for determination of serum levels of interleukin?6, tumor necrosis factor?alpha and interleukin?13. Rocuronium 3. 5 mg∕kg was then injected via the caudal vein. The IAP was recorded at 1, 5 and 10 min after administration. The intra?cellular free Ca2+ concentration was assessed using fura?2, and the maximal Ca2+ uptake and release rate in the sarcoplasmic reticulum were calculated. Results Compared with group C, the serum levels of interleu?kin?6 and tumor necrosis factor?alpha at 2 h after operation and IAP at 1 and 2 h after operation were signifi?cantly increased, the IAP was increased at 1, 5 and 10 min after administration of rocuronium, and the maximal Ca2+ uptake rate and amount of calcium uptake in the sarcoplasmic reticulum were decreased in group P ( P<0.01) . Conclusion Acute peritonitis decreases rocuronium?induced neuromuscular blockade in abdominal muscles, which may be related to the impaired Ca2+uptake function of the sarcoplasmic reticu?lum of rats.

ABSTRACT

AIM: To investigate the feasibility of early reversal of vecuronium with neostigmine. METHODS: 48 patients (ASA class I or II) scheduled for elective surgery undergoing general anaethesia were randomly assigned to vecuronium group (n=16) and vecuronium+ neostigmine group (n=32). Furthermore, the latter was divided into two groups according to the time of reversal. In vecuronium+ neostigmine group 1, the patients received neostigmine antagonization within 10 min after vecuronium administration,and in vecuronium+neostigmine group 2, time of reversal within 11-30 min after vecuronium administration. All patients received vecuronium 1.5 mg?kg -1 after general anesthesia. Neostigmine 0.05 mg?kg -1 +atropine 0.5 - 1.0 mg+saline 8 ml was administered to vecuronium+ neostigmine group and recovery was compared with that of vecuronium patients who received 8 ml saline. The time from vecuronium administration to recovery of?TOF? 0.25 ?and? 0.7 ?was recorded.?RESULTS: In vecuronium group, the recovery time to TOF 0.25 and 0.7 was ( 45.58 ? 8.88 ) min, and ( 67.59 ? 5.60 ) min, respectirely; in vecuronium+ neostigmine group 1,it was ( 23.45 ? 2.82 ) min, and ( 31.86 ? 3.36 ) min, respectirely; and in vecuronium+neostigmine group 2, it was ( 28.70 ? 4.13 ) min,and ( 38.86 ? 2.10 ) min, respectirely.
