Objective To investigate the effect of glycine N-methyl transferase (GNMT)on intrauterine adhesion (IUA)fibrosis and its related mechanism.Methods In vivo experiment:A total of 36 healthy female SD rats (SPF grade,6～8 weeks old and weighing from 180～220 g)were subjected in this study.IUA model of SD rats and IUA model of GNMT overexpressed rats were established.RT-qPCR and immunofluorescence assay were applied to detect GNMT expression level in normal uterus and model group.RT-qPCR and Western blotting were used to detect the mRNA and protein levels of fibrosis-related molecules and the activation of TGF-β1/Smad3 signaling pathway in each group.The number of endometrial glands in each group was observed by HE staining.Masson staining was used to analyze the severity of endometrial fibrosis in each group.In vitro experiment:transformed human endometrial stromal cells (THESCs)fibrotic phenotype model was constructed using TGF-β1,and THESCs stably transfected with GNMT overexpression lentvirus were treated with TGF-β1.RT-qPCR and Western blotting were used to detect the mRNA and protein expression of fibrosis-related molecules.The expression of TGF-β1/Smad3 signaling pathway was detected by Western blotting.TGF-β1/Smad3 signaling pathway was activated by TGF-β1/Smad signaling pathway activator (SRI-011381),and the expression of TGF-β1/Smad3 signaling pathway and key molecular proteins of fibrosis phenotype was measured with Western blotting.Results In vivo experiment,the mRNA and protein expression levels of GNMT were significantly decreased in the IUA rats than the control rats (P<0.05).Overexpression of GNMT decreased the mRNA and protein levels of fibrosis related molecules,Collagen Ⅰ,Collagen Ⅲ and FN in the IUA rats (P<0.05),and decreased the phosphorylation levels of TGF-β1 and its downstream Smad3 protein (P<0.05).HE and Masson staining showed that overexpression of GNMT could increase the number of endometrial glands and reduce the severity of fibrosis in the IUA rats (P<0.05).In vitro experiments:overexpression of GNMT decreased the mRNA and protein levels of Collagen Ⅰ,Collagen Ⅲ and FN associated with fibrotic phenotype of THESCs (P<0.05),and reduced the phosphorylation level of Smad3 protein,downstream of TGF-β1 (P<0.05).After activation of TGF-β1/Smad3 signaling pathway,the protein levels of TGF-β1/Smad3 signaling pathway and downstream fibrosis phenotype molecules,Collagen Ⅲ and FN,were significantly decreased in the LV-GNMT+SRI-011381 group.Conclusion Overexpression of GNMT can inhibit endometrial fibrosis by regulating TGF-β1/Smad3 signaling pathway,thus achieving therapeutic effect on IUA.

Objective To analyze the relationship of the volume of 87 brain regions with postnatal age and neurobehavior in full-term neonates.Methods A total of 75 full-term newborns[gestational age(39.38±1.22)weeks;male/female(51/24);postnatal age(11.11±6.67)days]without abnormalities on brain MRI(three-dimensional T1-weighted imaging,3D T1WI)at our hospital between November 2010 and September 2017 were retrospectively included.Based on the template of 87 brain regions,the neonatal brains were divided into 87 brain regions and their volumes were calculated by using V-shape Bottleneck network(VB-Net)deep learning segmentation technique,Pearson partial correlation and regression analysis were used to explore the relationship of the volume of each brain region with postnatal age and neurobehavioral scores.Results After adjusting for gestational age,birth weight,head circumference,body length and sex,66.7％of the regional brain volumes(58/87 brain regions)significantly increased with the postnatal age(correlation coefficient r:0.2-0.7,P＜0.05).The volumes of gray matter in bilateral lentiform nucleus,left caudate nucleus,right occipital lobe,right inferior temporal lobe,and bilateral anterior temporal lobe strongly correlated with the postnatal age(r＞0.50,P＜0.05).The gray matter volume of the right occipital lobe linearly increased with age(slope:100.67),and was positively correlated with behavioral scores(r=0.324,P＜0.01).Conclusion Most of regional brain volumes increase with the postnatal age during the neonatal period,and the fastest growth occurs in primary sensorimotor-related brain regions,presenting the spatial heterogeneity.Partial brain region grows with the development of behavioral ability.

Objective To explore the effect of exposure to noise of 3.0T magnetic resonance imaging(MRI)on children's cochlear function.Methods We prospectively recruited 72 children who underwent cranial MRI examination at our hospital from May to November 2018;3M earplugs and sponge mats were used for hearing protection during MRI scanning.Noise level(dBA)of each MRI sequence was detected with a nonmagnetic microphone and a sound level meter.Distortion product otoacoustic emissions(DPOAE)test at 2-7 kHz was performed 24 hours before and 30 minutes after the MRI examination.Paired t-test or Wilcoxon signed-rank test was used to analyze differences in DPOAE amplitude before and after the MRI examination.Results The average noise level of MRI measured in the study was(107.7±3.92)dBA.Compared with that before the MRI examination,the DPOAE amplitude(dB)changed little after the MRI examination;the range of amplitude differences in each age group was as follows:left ear(-0.24-1.10)and right ear(-0.24-0.74)in the 0-1 year-old group;left ear(-0.07-0.59)and right ear(-0.57-0.75)in the 2-5 year-old group;left ear(-0.36-0.44)and right ear(-0.30-0.57)in the 6-12 year-old group.No statistically significant difference was found(correction P＞0.05).Conclusion No potential impact of 3.0T MRI noise on children's cochlear function was observed under routine hearing protection.

ObjectiveTo investigate the clinical efficacy of Huangqi injection combined with Buzhong Yiqi acupuncture in the treatment of chronic fatigue syndrome （CFS） with Qi deficiency and its effects on TCM syndromes， fatigue symptoms， serum superoxide dismutase （SOD）， malondialdehyde （MDA）， and oxidized low-density lipoprotein （ox-LDL） levels. MethodA total of 200 patients with CFS of Qi deficiency were randomly divided into a control group （100 cases） and an observation group （100 cases）. The control group was treated with vitamin B compounds， and the observation group was treated with Huangqi injection combined with Buzhong Yiqi acupuncture for two weeks. The scores of TCM syndromes， fatigue symptoms， levels of serum SOD， MDA， and ox-LDL and the incidence of adverse reactions were observed and compared before and after treatment in two groups. ResultAfter treatment， the total effective rate of the control group was 54.34% （50/92）， while that of the observation group was 88.54% （85/96）. The total effective rate of the observation group was higher than that of the control group （χ²=27.13，P<0.05）. Compared with those in the two groups before treatment， scores of fatigue self-assessment scale （FSAS）， physical fatigue and mental fatigue， and sleep/rest response scores of fatigue in the two groups after treatment were significantly decreased （P<0.05）. After treatment， scores of FSAS， physical fatigue and mental fatigue， and sleep/rest response scores of fatigue in the observation group were significantly decreased compared with those in the control group （P<0.05）. Compared with those in the two groups before treatment， TCM syndrome scores in the two groups after treatment were significantly decreased （P<0.05）. After treatment， TCM syndrome scores in the observation group were significantly decreased compared with those in the control group （P<0.05）. Compared with those in the two groups before treatment， MDA levels in the two groups were significantly decreased （P<0.05）， ox-LDL levels in the observation group were significantly decreased （P<0.05）， and SOD levels were significantly increased （P<0.05）. After treatment， compared with those in the control group， the serum MDA and ox-LDL levels in the observation group were significantly decreased （P<0.05）， and the serum SOD was significantly increased （P<0.05）. No serious adverse events or adverse reactions occurred during this clinical trial. ConclusionHuangqi injection combined with Buzhong Yiqi acupuncture has a good clinical curative effect in the treatment of CFS with Qi deficiency， which can effectively improve the fatigue symptoms of patients， increase the level of SOD， and reduce the level of serum MDA and ox-LDL. It is related to the production of antioxidants， inhibiting the production of lipid peroxides， and improving the body's ability to resist oxidative stress.

AIM:To analyze the expression changes of O-linked N-acetylglucosamine(O-GlcNAc)glycoprotein in the lens capsule of age-related cataract and diabetic cataract and investigate the role of O-GlcNAc glycoprotein in diabetic cataract.METHODS: The lens capsules of 54 patients(56 eyes)with diabetic cataract and 115 patients(120 eyes )with age-related cataract were studied. Immunoblotting was used to detect the expression level of O-GlcNAc protein in the lens capsules of age-related and diabetic cataracts, and mass spectrometry was used to identify the O-GlcNAc glycoproteins in lens capsules.RESULTS: Immunoblotting results showed that the expression level of O-GlcNAc protein in the lens capsule of diabetic cataracts was significantly higher than in the age-related cataracts(P<0.01). With the level of glycosylated hemoglobin increasing, the expression level of O-GlcNAc protein also increased(P<0.01). Totally 5 O-GlcNAc proteins with up-regulated expression(FABP5, KRT16, PGK1, CTSD and S100A7), and 18 O-GlcNAc proteins with down-regulated expression(CRYβB1, etc.)were identified in the lens capsule of patients with diabetic cataract by mass spectrometry. Three new O-GlcNAc glycosylation sites were identified in this study. They were O-GlcNAcylation at T1730 position and S1738 position of PTPRQ and O-GlcNAcylation at T61 position of ATP5MC2.CONCLUSION:O-GlcNAc glycosylation may be involved in the formation and development of diabetic cataract. The differential O-GlcNAc glycoprotein identified by mass spectrometry provided the data for further study about pathogenesis of diabetic cataract.

MethodIn the experiment， 46% vol Red Star Erguotou （10 mL·kg·d^-1） was used to establish the AONFH rat model， and the intervention effect of JPHGP at different doses （2.5， 5.0， 10.0 g·kg^-1） was observed. Jiangusheng pill （JGS， 1.53 g·kg^-1） was selected as the positive control. After 8 weeks of administration， the bone histomorphometry of the femoral head was analyzed by Micro-CT imaging， and the area of medullary microvessels in the femoral head was detected by ink perfusion. The pathological change was observed by hematoxylin and eosin （HE） staining. The protein expressions of Platelet endothelial cell adhesion molecule-1 （CD31）， VEGF， VEGFR2， PI3K， phosphor-Akt （p-Akt） and phosphatase and Tensin homologue deleted on chromosome 10 （PTEN） in the femoral head were determined by immunohistochemistry and Western blot. ResultCompared with normal group， the model group presented the fracture and thinning of trabeculae in the femoral head， increased empty bone lacunae， and elevated number and diameter of adipocytes （P<0.01）. Micro-CT imaging revealed a decrease in bone mineral density （BMD）， bone volume fraction （BV/TV）， trabecular thickness （Tb.Th） and trabecular number （Tb.N） （P<0.05， P<0.01） while an increase in bone surface-to-volume ratio （BS/BV） and trabecular separation （Tb.Sp） （P<0.01）. The results of ink perfusion showed that the area of medullary microvessels in the femoral head was reduced （P<0.01）. Compared with model group， JPHGP lowered the empty bone lacunae rate as well as the number and diameter of adipocytes in the femoral head of AONFH rats. Micro-CT imaging indicated that JPHGP low-dose group had elevated BV/TV， Tb.Th and Tb.N （P<0.05， P<0.01） while decreased BS/BV （P<0.01）， and there was an upward trend in BMD while a downward trend in Tb.Sp， but without statistical difference. In addition， JPHGP medium- and high-dose groups had a rise in BMD， BV/TV， Tb.Th and Tb.N （P<0.05， P<0.01）， a decrease in BS/BV and Tb.Sp （P<0.05， P<0.01） and enlarged area of medullary microvessels in the femoral head （P<0.05， P<0.01）. The expressions of CD31， VEGF， VEGFR2， PI3K， p-Akt in the model group were lower than those in the normal group （P<0.01）， and after medium and high doses of JPHGP treatment， the expressions of CD31， PI3K and p-Akt in the femoral head of rats were up-regulated （P<0.01） while the protein expression of PTEN was down-regulated （P<0.01）. Moreover， JPHGP up-regulated the expressions of VEGF and VEGFR2 （P<0.05， P<0.01）. ConclusionJPHGP can repair the vascular injury in AONFH， and its mechanism may be related to the activation of VEGF/VEGFR2/PI3K/Akt signaling pathway. This study provides certain scientific basis and reference for the clinical application of JPHGP. ObjecctiveTo observe the repair effect of Jianpi Huogu prescription （JPHGP） on vascular injury in experimental alcohol-induced osteonecrosis of femoral head （AONFH）， and to explore its mechanism based on vascular endothelial growth factor （VEGF）/VEGFR2/phosphoinositide 3-kinase （PI3K）/protein kinase B （Akt） signaling pathway.

Objective To investigate the relationship between corneal hysteresis(CH)and retinal nerve fiber layer(RNFL)thickness in patients with glaucoma.Methods In this study,186 eyes of 133 patients with open-angle glaucoma who attended the ophthalmology department of our hospital were included,with a follow-up of(3.8±0.8)years and an average of 9 visits.The CH measurements were acquired using the Ocular Response Analyzer,and RNFL thickness was measured at each follow-up using spectral domain optical coherence tomography.All statistical analyses were performed with Stata software.Univariate and multivariable linear regression models were used to investigate the relationship between age,baseline CH,intraocular pressure(IOP),central corneal thickness(CCT)and RNFL thickness.Results The aver-age baseline CH was(9.2±1.8)mmHg(1 kPa=7.5 mmHg),average baseline RNFL thickness was(76.4±18.1)μm,the average baseline IOP was(13.8±3.7)mmHg,and the average baseline CCT was(533±42)μm.Univariate model analysis showed that the baseline CH had a positive correlation with RNFL thickness(P＜0.05).The lower the CH,the thinner the RNFL.For every 1 mmHg reduction in CH,the thickness of RNFL was reduced by 0.13 μm,indicating that CH may be involved in the occurrence and development of glaucoma.The univariate model analysis also showed that there was a negative correlation between IOP and RNFL thickness(P＜0.05).The higher the IOP,the thinner the RNFL.However,there was no significant correlation between age,CCT and RNFL thickness(both P＞0.05).The multivariate model analy-sis showed that there was a positive correlation between baseline CH and RNFL thickness during the follow-up,excluding the influence of age,IOP and CCT(P＜0.05).For every l mmHg reduction in CH,the thickness of RNFL was reduced by 0.13 μm.Conclusion There is a positive correlation between baseline CH and RNFL thickness in glaucoma.The lower the CH,the thinner the RNFL.Low CH may be a risk factor for the progression of glaucoma.

Objective:To investigate the curative effects of Beck's cognitive therapy (BCT) combined with transcranial magnetic stimulation (TMS) on post-stroke sleep disorders in patients.Methods:A total of 120 patients with post-stroke sleep disorders who were diagnosed and treated in Wenzhou Hospital of Integrated Traditional Chinese and Western Medicine between January and December 2020 were included in this study. They were randomly assigned to undergo TMS (TMS group), BCT (BCT group), or TMS plus BCT (combined group) ( n = 40/group). Before and after treatment, sleep quality and mental state scores were evaluated in each group. Results:After treatment, the Pittsburgh Sleep Quality Index (PSQI) score in the combined group [(5.68 ± 0.33) points] was significantly lower than that in the TMS group [(9.11 ± 0.83) points] and BCT group [(11.37 ± 1.06) points, F = 512.63, P < 0.001]. Sleep efficiency in the combined group [(56.73 ± 2.62)%] was significantly higher than that in the TMS group [(39.55 ± 3.02)%] and BCT group [(35.23 ± 1.41)%, F = 863.59, P < 0.001]. The Self-Rating Anxiety Scale (SAS) scores and Self-Rating Depression Scale (SDS) scores were significantly lower in the combined group compared with the TMS and BCT groups ( F = 412.52, 310.60, both P < 0.001). Conclusion:BCT combined with TMS can effectively improve sleep quality and reduce negative emotions in patients with post-stroke sleep disorders.
