Integrated management during the perinatal period for total anomalous pulmonary venous connection / 中国当代儿科杂志

OBJECTIVES@#To evaluate the clinical effectiveness of integrated management during the perinatal period for fetuses diagnosed with total anomalous pulmonary venous connection (TAPVC) by prenatal echocardiography.@*METHODS@#Clinical data of 64 cases of TAPVC fetuses diagnosed by prenatal echocardiography and managed with integrated perinatal care in Qingdao Women and Children's Hospital from January 2017 to December 2021 were retrospectively analyzed. Integrated perinatal care included multidisciplinary collaboration among obstetrics, fetal medicine, ultrasound, pediatric cardiology, pediatric anesthesia, and neonatology.@*RESULTS@#Among the 64 TAPVC fetuses, there were 29 cases of supracardiac type, 27 cases of intracardiac type, 2 cases of infracardiac type, and 6 cases of mixed type. Chromosomal analysis was performed in 42 cases, and no obvious abnormalities were found. Among the 64 TAPVC fetuses, 37 were induced labor, and 27 were followed up until term birth. Among the 27 TAPVC cases, 2 cases accepted palliative care, 2 cases were referred to another hospital for treatment and lost to follow-up, while the remaining 23 cases underwent primary repair surgery. One case died within 6 months after the operation due to low cardiac output syndrome, while the other 22 cases were followed up for (2.1±0.3) years with good outcomes (2 cases underwent a second surgery within 1 year after the first operation due to anastomotic stenosis or pulmonary vein stenosis).@*CONCLUSIONS@#TAPVC fetuses can achieve good outcomes with integrated management during the perinatal period.

Advances on pentraxin 3 in osteoporosis and fracture healing / 中国骨伤

Pentaxin 3 (PTX3), as a multifunctional glycoprotein, plays an important role in regulating inflammatory response, promoting tissue repair, inducing ectopic calcification and maintaining bone homeostasis. The effect of PTX3 on bone mineral density (BMD) may be affected by many factors. In PTX3 knockout mice and osteoporosis (OP) patients, the deletion of PTX3 will lead to decrease of BMD. In Korean community "Dong-gu study", it was found that plasma PTX3 was negatively correlated with BMD of femoral neck in male elderly patients. In terms of bone related cells, PTX3 plays an important role in maintaining the phenotype and function of osteoblasts (OB) in OP state;for osteoclast (OC), PTX3 in inflammatory state could stimulate nuclear factor κ receptor activator of nuclear factor-κB ligand (RANKL) production and its combination with TNF-stimulated gene 6(TSG-6) could improve activity of osteoclasts and promote bone resorption;for mesenchymal stem cells (MSCs), PTX3 could promote osteogenic differentiation of MSCs through PI3K/Akt signaling pathway. In recent years, the role of PTX3 as a new bone metabolism regulator in OP and fracture healing has been gradually concerned by scholars. In OP patients, PTX3 regulates bone mass mainly by promoting bone regeneration. In the process of fracture healing, PTX3 promotes fracture healing by coordinating bone regeneration and bone resorption to maintain bone homeostasis. In view of the above biological characteristics, PTX3 is expected to become a new target for the diagnosis and treatment of OP and other age-related bone diseases and fracture healing.

Cardiovascular health status of Chinese adults based on "Life's Essential 8" score / 中华流行病学杂志

Objective: To assess the cardiovascular health status of adults in China by using the "Life's Essential 8" score, and provide reference for the development and improvement of cardiovascular disease prevention and control policies and measures. Methods: Chronic Disease and Nutrition Surveillance was conducted in 298 counties/districts in 2015 in 31 provinces (autonomous regions, municipalities) across China, multi-stage stratified cluster random sampling was used to select 45 households in each village or neighborhood, and 20 households were further selected to conduct dietary surveys. In this study, a total of 70 093 adults aged ≥20 years who completed the dietary survey and had complete information were included, their cardiovascular health status were assessed by using the "Life's Essential 8" score, a cardiovascular health scoring standard released by the American Heart Association in 2022. All results were adjusted using complex design-based sampling weights to achieve a better estimate of the population. Results: In 2015, the overall cardiovascular health score of Chinese adults aged ≥20 years was 73.3±12.6, the score was significantly higher in women (77.9±11.6) than in men (68.7±11.8), and higher in urban area (74.5±12.8) than in rural area (71.9±12.2), the differences were significant (P<0.001). It was estimated that about 0.25% (95%CI: 0.16%-0.33%) of adults in China had cardiovascular health score of 100, and 33.0% (95%CI: 31.6%-34.3%), 63.2% (95%CI: 62.1%-64.3%), and 3.9% (95%CI: 3.5%-4.2%) of adults had high, moderate and low cardiovascular health scores, respectively. The proportion of those with high cardiovascular health scores was relatively low in men, those with low education level, those with low income, those living in rural areas, and those living in southwest China (P<0.001). Of the eight factors, diet had the lowest mean score (46.0, 95%CI: 44.7-47.3), followed by blood pressure (59.4, 95%CI: 58.2-60.6) and tobacco exposure (61.4, 95%CI: 60.6-62.2). Conclusions: The cardiovascular health status of two-thirds of adult population in China needs to be improved. Diet, tobacco exposure, and blood pressure are the factors affecting the cardiovascular health of Chinese population, to which close attention needs to be paid, and men, rural residents, and those with lower socioeconomic status are key groups in cardiovascular health promotion.

Emodin Ameliorates High Glucose-Induced Podocyte Apoptosis via Regulating AMPK/mTOR-Mediated Autophagy Signaling Pathway / 中国结合医学杂志

OBJECTIVE@#To investigate the effect of emodin on high glucose (HG)-induced podocyte apoptosis and whether the potential anti-apoptotic mechanism of emodin is related to induction of adenosine-monophosphate-activated protein kinase (AMPK)/mammalian target of rapamycin (mTOR)-mediated autophagy in podocytes (MPC5 cells) in vitro.@*METHODS@#MPC5 cells were treated with different concentrations of HG (2.5, 5, 10, 20, 40, 80 and 160 mmol/L), emodin (2, 4, 8 µ mol/L), or HG (40 mmol/L) and emodin (4 µ mol/L) with or without rapamycin (Rap, 100 nmol/L) and compound C (10 µ mol/L). The viability and apoptosis of MPC5 cells were detected using cell counting kit-8 (CCK-8) assay and flow cytometry analysis, respectively. The expression levels of cleaved caspase-3, autophagy marker light chain 3 (LC3) I/II, and AMPK/mTOR signaling pathway-related proteins were determined by Western blot. The changes of morphology and RFP-LC3 fluorescence were observed under microscopy.@*RESULTS@#HG at 20, 40, 80 and 160 mmol/L dose-dependently induced cell apoptosis in MPC5 cells, whereas emodin (4 µ mol/L) significantly ameliorated HG-induced cell apoptosis and caspase-3 cleavage (P<0.01). Emodin (4 µ mol/L) significantly increased LC3-II protein expression levels and induced RFP-LC3-containing punctate structures in MPC5 cells (P<0.01). Furthermore, the protective effects of emodin were mimicked by rapamycin (100 nmol/L). Moreover, emodin increased the phosphorylation of AMPK and suppressed the phosphorylation of mTOR. The AMPK inhibitor compound C (10 µ mol/L) reversed emodin-induced autophagy activation.@*CONCLUSION@#Emodin ameliorated HG-induced apoptosis of MPC5 cells in vitro that involved induction of autophagy through the AMPK/mTOR signaling pathway, which might provide a potential therapeutic option for diabetic nephropathy.

Effective Components of Periploca forrestii Against Rheumatoid Arthritis by Targeting TNF-α / 中国实验方剂学杂志

ObjectiveTo analyze the effective components of Periploca forrestii against rheumatoid arthritis（RA）by targeting tumor necrosis factor （TNF）-α based on network pharmacology and experimental verification. MethodThe preliminary research of the research group found that the alcohol extracts of P. forrestii （CDLF and CQAF） had significant anti-RA activities，and 10 monomers with such activities were identified. The anti-RA activities of active monomers，CDLF， and CQAF were compared by the enzyme-linked immunosorbent assay （ELISA）with interleukin（IL）-6，nitric oxide （NO），IL-1β， and prostaglandin E2（PGE2）as indicators. Network pharmacology was employed to analyze the possible molecular mechanism of P. forrestii against RA. The targeting ability of P. forrestii chemical monomers to TNF-α was verified by TNF-α molecular docking，surface plasmon resonance （SPR）， and TNF-α-induced L929 injury model. ResultELISA showed that the anti-RA activities of CDLF and CQAF were significantly stronger than those of identified 10 active monomers. Network pharmacology analysis showed that the core targets of P. forrestii against RA were signal transducer and activator of transcription protein 3 （STAT3），TNF， and IL-6. Gene Ontology（GO） analysis revealed collagen catabolism，inflammatory response，positive regulation of nuclear factor kappa-B（NF-κB） transcription factor activity，and positive regulation of B cell proliferation. Kyoto Encyclopedia of Genes and Genomes （EKGG） pathway enrichment analysis demonstrated TNF signaling pathway，phosphoinositide 3-kinase（PI3K）/protein kinase B（Akt） signaling pathway，NF-κB signaling pathway，Toll-like receptor signaling pathway，mitogen-activated protein kinase（MAPK） signaling pathway， etc. Verification experiments by TNF-α molecular docking，SPR， and TNF-α-induced L929 injury model found that CDLF and CQAF had good binding activities and could manifestly antagonize TNF-α. However， the active components separated and identified from CDLF and CQAF did not show the same anti-TNF-α activity. ConclusionThe CDLF and CQAF of P. forrestii may treat RA by targeting TNF-α. The experiments found that the isolated chemical components had weaker binding activity to TNF-α than CDLF and CQAF. Meanwhile，the research group isolated chemical components with a minimum mass fraction of 0.25 ng·g-1 from P. forrestii， which suggested that the active components generated by binding to TNF-α with anti-RA activities were presumedly trace components .

Discussion on Treatment of Recurrent Genital Herpes with Zhulingtang： Based on Thought of "Lower Energizer Resembling Drainage" / 中国实验方剂学杂志

Recurrent genital herpes is a sexually transmitted disease induced by herpes simplex virus（HSV）， mainly manifested as erythema， papules， vesicles， erosion， and exudation on the skin and mucosal membranes of the genital and anal area， accompanied by burning pain， or tingling. Factors leading to its recurrence are overworking， fever， alcohol consumption， infection， sexual activity， etc. At least 1 in 10 of the 15-49-year-old population are infected with herpes simplex virus-2. There is currently no available method to completely remove the herpes simplex virus and prevent its recurrence， and recurrence seriously affects the quality of life and psychological health of patients. According to the theory of traditional Chinese medicine （TCM）， the recurrence of genital herpes is mostly related to wind， dampness， heat， yin deficiency of liver and kidney， internal injuries due to emotional disorder， and dietary preference. TCM has advantages in reducing its recurrence rate. The lower energizer is closely related to skin diseases， and "lower energizer resembles drainage". Thus， the lower energizer is closely related to water and damp metabolism. Recurrent genital herpes occurs in the lower energizer and belongs to lower energizer diseases， and the fluid metabolism and qi movement in lower energizer are closely related to the occurrence of the disease. Based on thought of "lower energizer resembling drainage" and the clinical characteristics of recurrent genital herpes， this paper considered malfunction of lower energizer as its pathogenesis. Thus， smoothing the lower energizer according to the prevailing circumstances is particularly important and the treatment principle should be dispersing the pathogen from lower energizer without damaging yin. Zhulingtang （Treatise on Cold Damage and Miscellaneous Diseases） cures the difficulty in urination and thirst with desire to drink by smoothing the lower energizer. Thus， Zhulingtang was selected to treat recurrent genital herpes. This study is expected to provide a new idea for its clinical diagnosis and treatment.

OBJECTIVE@#To compare the clinical efficacy between Wei's triple nine needling combined with esculin and digitalis glycosides eye drops and esculin and digitalis glycosides eye drops alone for presbyopia complicated with visual fatigue of liver depression and spleen deficiency.@*METHODS@#Forty-six cases (92 eyes) with presbyopia complicated with visual fatigue of liver depression and spleen deficiency were randomly divided into an observation group (23 cases) and a control group (23 cases, 2 cases dropped off). The cases in the observation group were treated with Wei's triple nine needling and esculin and digitalis glycosides eye drops. The acupoints included Shangming (Extra), Chengqi (ST 1), Cuanzhu (BL 2) to Jingming (BL 1), Sizhukong (TE 23) to Taiyang (EX-HN 5), etc; the needling was given once every other day, three times a week, and the eye drops were given one drop each time, three times a day. The cases in the control group were only treated with the eye drops. Both groups were treated for 7 days as one course of treatment, and 2 courses of treatment were given. The visual fatigue core symptoms score, adjustment amplitude, adjustment lag and best average corrected visual acuity were observed in the two groups before treatment, 1 week and 2 weeks into treatment, respectively.@*RESULTS@#Compared before treatment, the visual fatigue core symptoms scores in the two groups were decreased after 1-week and 2-week treatment (P<0.05); in the observation group, the adjustment amplitude was increased after 2-week treatment (P<0.05), while in the control group, the adjustment amplitude was increased after 1-week and 2-week treatment (P<0.05); in the observation group, the adjustment lag was decreased after 1-week and 2-week treatment (P<0.05). After 2-week treatment, the visual fatigue core symptoms score in the observation group was lower than that in the control group, and the adjustment amplitude was higher than that in the control group (P<0.05). There were no significant differences in adjustment lag and best average corrected visual acuity between the two groups after 1-week and 2-week treatment (P>0.05).@*CONCLUSION@#Wei's triple nine needling combined with esculin and digitalis glycosides eye drops could improve the visual fatigue and eye regulation ability in patients with presbyopia complicated with visual fatigue of liver depression and spleen deficiency, and the effect is better than esculin and digitalis glycosides eye drops alone.

The pulmonary pharmacokinetics and anti-inflammatory effect of anemoside B4 after intratracheal and intravenous administration / 药学学报

Anemoside B4 (B4), a main triterpenoid saponin from a traditional Chinese medicine plant, Pulsatilla chinensis, is a novel anti-inflammatory agent for protection from acute lung injury. We investigated the pulmonary availability and anti-inflammatory efficacy of B4 after intratracheal and intravenous dosing with a view to evaluating the suitability of inhalation delivery. All animal studies were performed under the guidelines approved by the Animal Care and Use Committee of Institute of Medicinal Plant Development, Chinese Academy of Medical Sciences (Approval No: SLXD-20181113046). In vitro evaluation of the aerodynamic characteristics and droplet size distribution showed that the aerosols generated by a commercially available nebulizer were well deposited in the respiratory tract. Following intratracheal administration, B4 underwent pulmonary absorption into the bloodstream, rendering an absolute bioavailability of 103%. Compared to intravenous delivery, intratracheal administration dramatically increased the drug availability in lung tissue of rats by more than 1 000-fold, leading to improved and prolonged concentrations of B4 in lung tissue up to 48 h. In addition, the intratracheal administration of B4 resulted in dose-dependent and prolonged anti-inflammatory efficacy in a lipopolysaccharide (LPS)-induced lung injury model in mice. The present results demonstrate that inhalation delivery of B4 is a promising approach to treat pulmonary inflammation with once-daily dosing.

Currently, the field of EV-based therapy has been rapidly growing, and two main therapeutic uses of EVs can be surmised: (i) exploiting stem cell-derived EVs as therapeutic agents; and (ii) employing EVs as natural therapeutic vectors for drug delivery. This review will discuss the recent advances in EV-based therapy in the treatment of renal disease.

Effect of moxibustion at "oppositely-located points" on neurogenic bladder after spinal cord injury and endoplasmic reticulum stress pathway in rats / 中国针灸

OBJECTIVE@#To observe the effect of moxibustion at oppositely-located points "Mingmen" (GV 4) and "Shenque" (CV 8) on the motor function of the hind limbs and bladder function in rats with neurogenic bladder after suprasacral spinal cord injury (SCI), so as to explore the effect of this therapy on bladder tissue apoptosis mediated by endoplasmic reticulum stress pathway.@*METHODS@#Twenty-eight female Wistar rats were randomly divided into a sham-operation group (8 rats) and a model establishment group (20 rats). Using the modified Allen's method, the spinal cord of T10 segment was injured to establish a neurogenic bladder model in the model establishment group. Sixteen rats were modeled successfully and then divided into a model group (8 rats) and a moxibustion group (8 rats). In the moxibustion group, 2 h after consciousness regaining from modeling anesthesia, moxibustion was exerted at "Shenque" (CV 8) and "Mingmen" (GV 4), 2 cones at each acupoint in one intervention. The intervention was administered once every two days and 5-time intervention was required totally. After intervention, Basso, Beattie and Bresnahan locomotor rating scale (BBB) score for the motor function of the hind limbs, and the urodynamics indexes (maximum bladder capacity, urine leakage pressure and bladder compliance) were compared among groups. HE staining method was adopted to observe the morphological changes of bladder tissue. With Western blot method and real-time PCR assay, the protein and mRNA expressions of the endoplasmic reticulum stress-related genes (glucose- regulated protein 78 [GRP78], activating transcription factor 4 [ATF4] and cysteinyl aspartate specific proteinase-12 [Caspase-12]) were determined.@*RESULTS@#The transitional epithelial cells were arranged irregularly, the bladder wall was getting thinner, and the cellular vacuolar degeneration and neutrophil infiltration were found in the model group. Whereas, compared with the model group, in the moxibustion group, the arrangement of transitional epithelial cells was clear and continuous in layers, the cellular vacuolar degeneration was mild and the infiltration presented in a small amount of neutrophil granulocytes. Compared with the sham-operation group, in the model group, the BBB score was reduced (P<0.01), the maximum bladder capacity and bladder compliance were increased (P<0.01), and the protein expression levels of GRP78, ATF4 and Caspase-12, as well as mRNA expressions were all increased (P<0.01). In comparison with the model group, in the moxibustion group, BBB score was increased (P<0.01), the maximum bladder capacity and bladder compliance were decreased (P<0.01), and the protein and mRNA expression levels of GRP78, ATF4 and Caspase-12 were all decreased (P<0.01).@*CONCLUSION@#Moxibustion at the "oppositely-located points" improves the urination function, alleviate urine retention in neurogenic bladder rats after spinal cord injury. The underlying mechanism may be related to the down-regulation of the expressions of GRP78, ATF4 and Caspase-12 in the endoplasmic reticulum stress pathway of the bladder tissues, and thus to alleviate the apoptosis of bladder tissue.

Application of Radiopharmaceuticals in Targeted Tumor Therapies / 中国生物化学与分子生物学报

Objective:To explore the effect of different extracts of Thlaspi Herba on the gut microbiota of hyperuricemia mice， and to reveal the substance basis and mechanism of its hypouricemic activity. Method:Eighty-eight male Kunming mice were divided into 11 groups， including blank group， model group， allopurinol group， high and low dose groups of petroleum ether extract， high and low dose groups of ethyl acetate extract， high and low dose groups of <italic>n</italic>-butanol extract， high and low dose groups of total flavonoids extract. Mice in the blank group were given 0.5% sodium carboxymethylcellulose by gavage， and the other groups were given oteracil potassium （500 mg·kg^-1） by gavage to duplicate the hyperuricemia model. After modeling for several hours， the blank group and the model group were given distilled water by gavage， while mice in the allopurinol group were given allopurinol suspension （50 mg·kg^-1）， and mice in each treatment group were given high and low doses of corresponding extract （5， 2.5 g·kg^-1）. The serum uric acid （SUA） level and xanthine oxidase （XOD） activity were measured after 14 days. Fresh feces were collected for 16S rDNA sequencing. Result:Compared with the blank group， SUA level and XOD activity of model group were significantly increased （<italic>P</italic><0.05）. Compared with the model group， SUA level and XOD activity of the allopurinol group were significantly decreased （<italic>P</italic><0.01）. After intervention， SUA level were significantly decreased （<italic>P</italic><0.05， <italic>P</italic><0.01）， except for high dose and low dose groups of petroleum ether extract and low dose group of total flavonoids extract， XOD activity was significantly inhibited in low dose group of petroleum ether extract， high dose group of total flavonoids extract， and high and low dose groups of <italic>n</italic>-butanol extract （<italic>P</italic><0.05， <italic>P</italic><0.01）. The high dose group of total flavonoids extract was the most significant. The results of flora sequencing showed that <italic>α</italic> diversity and abundance of the model group changed significantly， and Bacteroidetes， Firmicutes and Lactobacillaceae were significantly correlated with XOD activity. After intervention， the operational taxonomic unit （OTU）， ACE， Chao1 and Shannon indexes of the high and low dose groups of total flavonoids extract were significantly increased （<italic>P</italic><0.05， <italic>P</italic><0.01）. Relative abundance of Bacteroidetes in low dose group of ethyl acetate extract， high dose group of total flavonoids extract， and high and low dose groups of <italic>n</italic>-butanol extract was significantly decreased （<italic>P</italic><0.01）， and the relative abundance of Firmicutes was significantly increased （<italic>P</italic><0.01）. The relative abundance of Lactobacillaceae in low dose group of <italic>n</italic>-butanol extract and high dose group of total flavonoids extract was significantly increased （<italic>P</italic><0.01）. Conclusion:The effective part of Thlaspi Herba for reducing uric acid is mainly flavonoids， the improvement of SUA level and XOD activity by affecting gut microbiota such as Lactobacillaceae， Bacteroidetes and Firmicutes， may be one of its mechanisms.

Effectiveness evaluation of health belief model-based health education intervention for patients with hypertension in community settings / 中华预防医学杂志

To evaluate the effectiveness of health belief model-based health education intervention in improving blood pressure control of patients with hypertension in community settings. From September 2016 to September 2017, 400 newly diagnosed patients with hypertension were recruited from 6 community healthcare centers with comparable population size and health services in the Shunyi District of Beijing. All community healthcare centers were randomly assigned to the intervention group (206 patients) and the control group (194 patients). Patients in the intervention group received 3 lectures (20-30 min for each) of health belief model-based health education. Patients in the control group received usual care. The basic characteristics, health beliefs, and health literacy were collected, and blood pressure was measured before and after the intervention, respectively. The difference-in-difference model was used to analyze the change of blood pressure and the influencing factors between two groups before and after the intervention. A total of 134 patients in the intervention group and 129 patients in the control group completed the study. After adjusting for the age, gender, family income, medical insurance, chronic diseases and family history, the score of perceived barriers was increased by 1.65 (0.016), and perceived seriousness was decreased by 0.73 (0.018). The systolic blood pressure of patients was decreased by 7.37 mmHg (1 mmHg=0.133 kPa, 0.001) and diastolic blood pressure was decreased by 4.07 mmHg (0.014), respectively. The β (95) values were -7.37 (-11.88,-2.86) and -4.07 (-7.30, -0.84). The perceived susceptibility and self-efficacy had a significant influence on the blood pressure of patients (0.05). Health belief model-based health education intervention could significantly improve the blood pressure control of patients with hypertension in the community settings.

Effect of Three Handing-Three Points on Pain Function and Expression of CX3CL1/CX3CR1 in Spinal Cord Dorsal Horn of Rats with Sciatic Nerve Injury / 中国康复理论与实践

Objective:To investigate the mechanism of Three Handing-Three Points on pain function in sciatic nerve injury rats by observing the changes of chemokine (C-X3-C motif) ligand 1, CX3CL1)/chemokine (C-X3-C motif) receptor 1 (CX3CR1) protein and mRNA expression in spinal dorsal horn. Methods:A total of 74 male Sprague-Dawley rats were randomly divided into normal group (n= 12), sham group (n = 24), model group (n = 25), and Three Handing-Three Points group (Tuina group,n = 13). The model group and Tuina group prepared the sciatic nerve injury model. The sham group exposed sciatic nerve only. Tuina group received Tuina on Yinmen (BL37), Chengshan (BL57) and Yanglingquan (GB34) with Tuina manipulation emulator. The photothermal pain threshold was measured seven days after modeling and after 20 days of intervention; cumulative pain score was measured seven days after modeling, and after ten days and 20 days of intervention. The spinal dorsal horn tissues were extracted to detect the protein and mRNA expression of CX3CL1/CX3CR1 with Western blotting and RT-PCR seven days after modeling and after 20 days of intervention. The microglia morphology in spinal dorsal horn was observed with immunofluorescence after 20 days of intervention. Results:Seven days after modeling, compared with the normal group, the photothermal pain tolerance threshold increased in the model group and the sham group (P < 0.05); compared with the sham group, the cumulative pain score increased in the model group and Tuina group (P < 0.05). After ten days of intervention, the cumulative pain score was lower in Tuina group than in the model group (P < 0.05). After 20 days of intervention, both the photothermal pain tolerance threshold and cumulative pain score were lower in Tuina group than in the model group (P < 0.05). There was no significant difference in the expression of CX3CL1/CX3CR1 protein and mRNA on the seven days after modeling and after 20 days of intervention (P > 0.05). The microglia in the model group were partially activated or completely activated, while those in Tuina group were unactivated or partially activated after 20 days of intervention. Conclusion:Three Handing-Three Points can improve the pain function of sciatic nerve injured rats, which may associate with regulating microglia through the pathway other than CX3CL1/CX3CR1.

Advance in Repeatitive Transcranial Magnetic Stimulation for Dysphagia after Stroke (review) / 中国康复理论与实践

Repeatitive transcranial magnetic stimulation can adjust cortical excitability and improve swallowing function in patients with dysphagia after stroke. High frequency stimulations with 90% to 130% resting motor threshold (rMT) in the early stage, as well as low frequency stimulations with 100% to 130% rMT for 1200 pulse in the recovery period, may be beneficial to the recovery of swallowing function, and bilateral stimulation may be more effective.

Imaging Features of Abnormal Neural Connectivity in Autistic Children / 中国康复理论与实践

Objective:To analyze the structure and function of white matter in autistic children by using diffusion tensor imaging (DTI) and magnetic resonance spectroscopy (MRS), to explore the imaging features of abnormal neural connectivity in children with autism. Methods:Autism group (n = 14) and control group (n = 8), aged two to nine years, underwent DTI and MRS scan. Bilateral frontal lobe, hippocampus, genu and splenium of corpus callosum and cerebellum white matter were selected as regions of interest. The data of DTI and MRS were processed by Functool 2.6 software of GEAW4.2 workstation. The fractional anisotropy (FA) and apparent diffusion coefficient (ADC) of DTI, the absolute concentrations of N-acetylaspartate (NAA), choline (Cho), creatinine (Cr) and the ratios of NAA/Cr and Cho/Cr were recorded respectively. Results:Compared with the control group, the FA of left hippocampus (F = 5.922, P = 0.033) and the absolute concentration of Cr in left and right hippocampus (F > 4.715, P < 0.05) decreased significantly in the autism group. The FA was lower in left corpus callosum genu than in the right one (F = -2.335, P = 0.042), and the ADC was higher in left corpus callosum splenium than in the right one (F = 3.520, P < 0.01) in the autism group. The absolute concentration of NAA, Cho and Cr in left frontal lobe (|t| > 2.648, P < 0.05), the absolute concentration of NAA in left corpus callosum splenium (t = -3.076, P = 0.009) and Cho/Cr in left cerebellum (t = -2.225, P = 0.044) were significantly lower than those in the right cerebral hemisphere in the autism group. The DTI and MRS indexes were not different between left and right hemispheres in the control group (P > 0.05). Conclusion:Abnormal metabolite or functional alternations were found in the frontal lobe, hippocampus, cerebellum and the genu and splenium of the corpus callosum in autistic children, suggesting underconnectivity intra- or inter-hemispheric neural, especially in left hemisphere.

Effects of Three Handing-Three Points on Motor Function and Expression of Transforming Growth Factor-β1/Smad2 Pathway in Injured Sciatic Nerve of Rats / 中国康复理论与实践

Objective:To investigate the effect of Tuina of Three Handing-Three Points on the motor function of hind limbs, the proliferation of Schwann cell, recovery of myelin sheath and the expression of transforming growth factor (TGF)-β1/Smad2 pathway protein in injured sciatic nerve of rats. Methods:A total of 66 male Sprague-Dawley rats were randomly divided into sham operation group (n = 22), model group (n = 22) and observation group (n = 22). The sciatic nerve injury model was made by clamping method. On the eighth day after modeling, the observation group received stimulation on Yinmen (BL37), Chengshan (BL57) and Yanglingquan (GB34). The sciatic functional index (SFI) was measured before intervention and 21 days after intervention. The Oblique Plate Test was performed before intervention, and seven days, 14 days and 21 days after intervention. The expression of S100, TGF-β1 and Smad2 were observed by immunofluorescence. The expression of TGF-β1, Smad2 and p-Smad2 was detected by Western blotting. Results:Before intervention, SFI was lower in the model group and observation group than in the sham operation group (P < 0.05); 21 days after intervention, SFI and the angle of Oblique Plate Test were higher in the observation group than in the model group (P < 0.05). Immunofluorescence showed that, 21 days after intervention, the expression of S100 was lower in the model group than in the sham operation group (P < 0.01), and was higher in the observation group than in the model group (P < 0.05), no difference was found between the observation group and the sham operation group (P > 0.05). Western blotting showed that, before intervention and seven days after intervention, the expression of TGF-β1, Smad2 and p-Smad2 were higher in the model group than in the sham operation group; 21 days after intervention, no difference was found in the expression among groups (P > 0.05) Conclusion:Three Handing-Three Points could promote the proliferation of Schwann cell and the recovery of myelin sheath, to improve the motor function of hind limbs in rats with sciatic nerve injury, which may not be related to TGF-β1/Smad2 pathway.

Effects of Three Handing-Three Points on Thickness of Myelin Sheath and Expression of Neuregulin 1 and Human Epidermal Growth Factor Receptor 2 after Sciatic Nerve Injury in Rats / 中国康复理论与实践

Objective:To explore the effect of Tuina of Three Handing-Three Points on the recovery of motor function, the expression of neuregulin (NRG) 1 and human epidermal growth factor receptor (ErbB) 2 in the injured point of sciatic nerve and L4-6 spinal cord, and the morphological change of myelin sheath at the injured point of sciatic nerve of rats. Methods:A total of 76 male Sprague-Dawley rats were randomly divided into normal group, sham operation group, model group and Tuina group with 19 rats in each group. The right side sciatic nerve was clamped to make model in the model group and Tuina group. The sham operation group exposed sciatic nerve only. Tuina group received Tuina on Yinmen (BL37), Chengshan (BL57) and Yanglingquan (GB34) with dialing, plucking and kneading using Tuina technique simulator. All of them were tested with Oblique Plate Test before modeling, seven days and 28 days after modeling. Western blotting was used to detect the protein expression of NRG1 and ErbB2 in the injured point of sciatic nerve and L4-6 spinal cord. The change of myelin sheath at the sciatic nerve injury point was observed and analyzed by transmission electron microscope. Results:Seven days and 28 days after modeling, the scores of Oblique Plate Test were lower in the model group and Tuina group than in the normal group and the sham operation group (P < 0.05); 28 days after modeling, the scores was higher in Tuina group than in the model group (P < 0.05). At the sciatic nerve injury point, three days after modeling, the expression of NRG1 and ErbB2 was higher in the model group and Tuina group than in the normal group and the sham operation group (P < 0.05); seven days and 28 days after modeling, there was no significant difference in NRG1 among groups (P > 0.05); 28 days after modeling, the expression of ErbB2 was higher in the model group and Tuina group than in the normal group and the sham operation group (P < 0.05). In L4-6 spinal cord, three days after modeling, the expression of NRG1 and ErbB2 was higher in the model group and Tuina group than in the normal group and sham operation group (P < 0.05); seven days after modeling, the expression of NRG1 was higher in the model group and Tuina group than in the sham operation group (P < 0.05), and the expression of ErbB2 was higher in the model group and Tuina group than in the normal group and the sham operation group (P < 0.05); 28 days after modeling, the expression of NRG1 was higher in Tuina group than in the model group (P < 0.05), and there was no significant difference in ErbB2 among groups (P > 0.05). The electron microscope showed that, 28 days after modeling, the myelin sheath collapsed seriously in the model group; while the ultrastructure of the nerve injury point improved, and the myelin sheath of the nerve fiber was relatively intact in Tuina group; the g-ratio value was lower in the model group than in the sham operation group (P < 0.05), the g-ratio value was higher in Tuina group than in the model group (P < 0.05), and no difference was found in g-ratio value between Tuina group and sham operation group (P > 0.05). Conclusion:Three Handing-Three Points could improve the motor function of hind limbs in rats with sciatic nerve injury, which may be related to the adjustment of NRG1 and ErbB2 in the sciatic nerve and spinal cord, to maintain normal myelin sheath structure.
