Objective To investigate the therapeutic effect of acupuncture for restoring consciousness and inducing resuscitation in promoting revival of coma for the patient of diffuse axonal injury(DAI). Methods 60 cases of DAI (GCS≤ 8) were randomly recurited into a control group and a treatment group. The control group was treated by routine treatment, while the treatment group was treated with acupuncture on the basis of routine treatment .The improving rate of consciousness at the two months of treatment was compared between the two group, and the prognosis was evaluated according to GOS scores. Results The revival rate in the treatment group was 86.7%, higher than that of 60.0% in the control group (P<0.05). The revival time in the treatment group was shorter than the control group (X2=5.45、 t= 8.051, P<0.05 ) .Conclusion The integrated therapy of acupuncture for restoring consciousness and inducing resuscitation and western medicine can promote the effect of coma revival and improve life condition for the patient of DAI.

Neuromyelitis optica (NMO) is an inflammatory-demyelinating disease of central nervous system that is characterized by severe attacks of optic neuritis (ON) and longitudinally extensive transverse myelitis (LETM).Conventional MRI is the most sensitive method in detection of NMO lesions in brain,spinal cord and optic nerve,which can objectively show the site,number,size and distribution of lesions.The MRI features of NMO lesion in brain,spinal cord and optic nerve lesions were reviewed in this article.

AIM:To assess the protective role of melatonin(MEL)in a rat model of oleic-induced acute lung injury.METHODS:Twenty-four rats were randomly allocated to three groups as follows:saline(NS)injection group,oleic acid(OA)injection group and MEL plus OA injection group,the lavage protein,lung wet-to-dry weight ratio,malondialdehyde(MDA)content,superoxide dismutase(SOD)activity and lung histopathology were examined.RESULTS:(1)Injection 0.15 mL/kg of OA led to a severe acute lung injury(ALI),characterized by significantly increasing in lavage protein,lung coefficient(P＜0.01),and by histopathological alterations which presented hemorrhage,edema.thickened alveolar septum and the existence of inflammatory cells in alveolar spaces;(2)Infusion of MEL(20 mg/kg,intraperitoneally for 60 min before the oleic acid)markedly alleviated above-mentioned symptom induced by OA,consistent with decrease of MDA level(P＜0.01) and the increase of SOD activty(P＜0.01).CONCLUSION:Pre-treatment with MEL can attenuate the OA -induced ALI in rats via cleaning and preventing the formation of free radicals and further lessening the increase of alveolocapillary membrane permeability,these data suggest that MEL may be effective in the prevention of ALI.

Abstract: Objective To analyze the causes of foodborne illness outbreaks in Inner Mongolia, so as to provide reference for understanding systemic risks and formulating prevention and control measures. Methods Data on foodborne disease outbreaks in Inner Mongolia Autonomous Region from 2016 to 2021 were collected through the "Foodborne Disease Outbreak Monitoring System" for attribution analysis. Results A total of 591 outbreak events were included from 2016 to 2021. Single -dimensional attribution analysis showed that the main causes of foodborne disease outbreaks in this region were vegetables and vegetable products, and meat and meat products, respectively accounting for 20.5% (121/591) and 12.6% (75/591) of the total events. leading contributing factor was improper processing, accounting for 16.2%(96/591), and the main pathogenic factor was toxic plants and their toxins, accounting for 14.9%(88/591). Multi-dimensional attribution analysis showed that the highest number of outbreak events occurred in summer, with 290 cases accounting for 49.1% (290/591) of the total number of events. The eastern, central, and western regions also had the highest number of events in summer, accounting for 53.6% (180/336), 39.5% (60/152), and 48.5% (50/103) of the total number of events in this region, respectively. Among vegetables and vegetable products, improper processing led to the majority of outbreaks caused by toxic plants and their toxins, accounting for 58.7% (71/121) of total events. For meat and meat products, improper storage resulting in the most outbreaks of biological pollution, accounting for 16.0%(12/75) of the total number of meat and meat product incidents. Majorities of death cases were primarily due to accidental ingestion or misuse of non-food items (such as poisonous mushrooms), comprising 38.5% (5/13) of total deaths. Conclusions The main food, triggering factors, and pathogenic factors involved in the outbreak of foodborne diseases in this region are relatively routine and controllable. Therefore, efforts should be made to strengthen public food safety education to reduce the occurrence of foodborne diseases.

Objective:To compare the efficacy of reduction and in situ intervertebral fusion fixation in the treatment of degenerative lumbar spondylolisthesis.Methods:A total of 182 patients (92 males and 90 females) with L 4 degenerative lumbar spondylolisthesis of Meyerding's classification of grade I and grade II, aged (62.6±6.8) years (range, 57-73 years), who underwent posterior L 4, 5 internal fixation and interbody fusion in the Department of Spinal Surgery, the Second Hospital of Shanxi Medical University, were retrospectively analyzed from January 2019 to December 2022. There were 105 cases of I-degree spondylolisthesis and 77 cases of II-degree spondylolisthesis. According to the operation method, the patients were divided into reduction intervertebral fusion fixation (reduction group) and in situ intervertebral fusion fixation group (in situ group). Imaging parameters such as lumber lordosis (LL), pelvic incidence (PI)-LL, L 3, 4 intervertebral space heights, fusion segment angle, and sagittal vertical axis (SVA) were measured on the pre- and post-surgical lumbar spine lateral radiographs. The visual analogue scale (VAS) and Oswestry Disability Index (ODI) of low back pain were recorded before and after surgery. The differences in clinical and imaging parameters were compared between reduction and in situ fusion group. Results:All 182 patients successfully completed the surgery and were followed up for 12.0±2.4 months (range, 9-15 months). The LL of the reduction group before surgery, immediately after surgery, and at the last follow-up were 46.9°±7.1°, 57.2°±5.9°, 55.6°±5.5°, respectively, with statistically significant differences ( F=87.61, P<0.001), with immediate and final follow-up being smaller than those in the in situ fixation group. The LL of the in situ fixation group before surgery, immediately after surgery, and at the last follow-up were 47.8°±7.2°, 50.5°±7.0°, and 48.7°± 6.4°, respectively, with no statistically significant difference ( F=2.83, P=0.062). The immediate and final follow-up of LL in the reduction group was lower than those in the in situ fixation group ( P<0.05). The fusion segment angles of the reduction group before surgery, immediately after surgery, and at the last follow-up were 14.2°±5.1°, 23.2°±4.7°, 23.2°±4.7°, respectively, with statistically significant differences ( F=152.87, P<0.001), with immediate and final follow-up after surgery being greater than before surgery. The fusion segment angles of the in situ fixation group before surgery, immediately after surgery, and at the last follow-up were 15.4°±5.9°, 18.2°±5.5°, and 17.4°±5.1°, respectively, with statistically significant differences ( F=4.69, P=0.009), with immediate and final follow-up being greater than before surgery. The fusion segment angulation in the reduction group was greater than that in the in situ fixation group at both the immediate and final follow-up ( P<0.05). The SVA of the reduction group before surgery, immediately after surgery, and at the last follow-up were 16.9±18.2 mm, 9.5±12.0 mm, and 8.7±11.3 mm, respectively, with statistically significant differences ( F=11.32, P<0.001), with immediate and final follow-up being smaller than before surgery. The SVA of immediately after surgery and at the last follow-up were both smaller than before surgery. The SVA of the in situ fixation group before surgery, immediately after surgery, and at the last follow-up were 16.4±17.2 mm, 14.3±15.5 mm, and 13.8±15.0 mm, respectively, with no statistically significant difference ( F=0.57, P=0.576). The SVA of the reduction group at immediate and final follow-up was lower than that of the in situ fixation group ( P<0.05). Conclusion:Both reduction and in situ intervertebral fusion fixation can effectively relieve the clinical symptoms of patients. Fusion fixation after reduction can improve the angulation of fusion segments to form segmental kyphosis, which is more conducive to improving SVA.

The seat of human intelligence is the human cerebral cortex, which is responsible for our exceptional cognitive abilities. Identifying principles that lead to the development of the large-sized human cerebral cortex will shed light on what makes the human brain and species so special. The remarkable increase in the number of human cortical pyramidal neurons and the size of the human cerebral cortex is mainly because human cortical radial glial cells, primary neural stem cells in the cortex, generate cortical pyramidal neurons for more than 130 days, whereas the same process takes only about 7 days in mice. The molecular mechanisms underlying this difference are largely unknown. Here, we found that bone morphogenic protein 7 (BMP7) is expressed by increasing the number of cortical radial glial cells during mammalian evolution (mouse, ferret, monkey, and human). BMP7 expression in cortical radial glial cells promotes neurogenesis, inhibits gliogenesis, and thereby increases the length of the neurogenic period, whereas Sonic Hedgehog (SHH) signaling promotes cortical gliogenesis. We demonstrate that BMP7 signaling and SHH signaling mutually inhibit each other through regulation of GLI3 repressor formation. We propose that BMP7 drives the evolutionary expansion of the mammalian cortex by increasing the length of the neurogenic period.

Medium spiny neurons (MSNs) in the striatum, which can be divided into D1 and D2 MSNs, originate from the lateral ganglionic eminence (LGE). Previously, we reported that Six3 is a downstream target of Sp8/Sp9 in the transcriptional regulatory cascade of D2 MSN development and that conditionally knocking out Six3 leads to a severe loss of D2 MSNs. Here, we showed that Six3 mainly functions in D2 MSN precursor cells and gradually loses its function as D2 MSNs mature. Conditional deletion of Six3 had little effect on cell proliferation but blocked the differentiation of D2 MSN precursor cells. In addition, conditional overexpression of Six3 promoted the differentiation of precursor cells in the LGE. We measured an increase of apoptosis in the postnatal striatum of conditional Six3-knockout mice. This suggests that, in the absence of Six3, abnormally differentiated D2 MSNs are eliminated by programmed cell death. These results further identify Six3 as an important regulatory element during D2 MSN differentiation.
