Objective: To observe the immediate effect of small-angle Tui-Pushing and An-Pressing anti-rotation bone-setting manipulation in improving the correction of braces for adolescent idiopathic scoliosis. Methods: A total of 50 cases of adolescent idiopathic scoliosis were selected and given brace correction first. The whole spine anteroposterior and lateral radiographs were taken, the Cobb angle was measured, and the visual analog scale (VAS) score of pain caused by brace wearing was recorded. After removal of the brace, small-angle Tui-Pushing and An-Pressing anti-rotation bone-setting manipulation was performed once. After treatment, the same brace was put on again to take a whole spine anteroposterior radiograph, the Cobb angle was measured, and the VAS score was recorded. The changes in Cobb angle and VAS score after manipulation were compared, and the immediate efficacy was evaluated. Results: After the manipulation, the Cobb angle was significantly smaller than that before treatment (P<0.01) and the VAS score was significantly lower than that before treatment (P<0.01). Conclusion: Small-angle Tui-Pushing and An-Pressing anti-rotation bone-setting manipulation can improve the immediate efficacy of brace in treating adolescent idiopathic scoliosis and relieve the pain caused by brace wearing at the same time.

The testis is pivotal for male reproduction, and its progressive functional decline in aging is associated with infertility. However, the regulatory mechanism underlying primate testicular aging remains largely elusive. Here, we resolve the aging-related cellular and molecular alterations of primate testicular aging by establishing a single-nucleus transcriptomic atlas. Gene-expression patterns along the spermatogenesis trajectory revealed molecular programs associated with attrition of spermatogonial stem cell reservoir, disturbed meiosis and impaired spermiogenesis along the sequential continuum. Remarkably, Sertoli cell was identified as the cell type most susceptible to aging, given its deeply perturbed age-associated transcriptional profiles. Concomitantly, downregulation of the transcription factor Wilms' Tumor 1 (WT1), essential for Sertoli cell homeostasis, was associated with accelerated cellular senescence, disrupted tight junctions, and a compromised cell identity signature, which altogether may help create a hostile microenvironment for spermatogenesis. Collectively, our study depicts in-depth transcriptomic traits of non-human primate (NHP) testicular aging at single-cell resolution, providing potential diagnostic biomarkers and targets for therapeutic interventions against testicular aging and age-related male reproductive diseases.

OBJECTIVE: To observe the skin surface microcirculation of acupoints of conception vessel, governor vessel and thoroughfare vessel in patients with primary dysmenorrhea using laser speckle contrast imaging (LSCI), and provide acupoint selection basis of acupuncture-moxibustion for primary dysmenorrhea. METHODS: Ninety-nine healthy female college students with regular menstrual cycles (normal group) and 94 female college students with primary dysmenorrhea (dysmenorrhea group) were recruited. Before menstrual period, on the first day of menstruation, and on the third day after menstruation, LSCI was used to observe the surface microcirculation at the abdominal acupoints of conception vessel, i. e. Yinjiao (CV 7), Qihai (CV 6), Shimen (CV 5), Guanyuan (CV 4), Zhongji (CV 3) and Qugou (CV 2), acupoints of thoroughfare vessel, i. e. Huangshu (KI 16), Zhongzhu (KI 15), Siman (KI 14), Qixue (KI 13), Dahe (KI 12), Henggu (KI 11) and acupoints of lumbosacral region of governor vessel, i. e. Xuanshu (GV 5), Mingmen (GV 4), Yaoyangguan (GV 3), Yaoshu (GV 2) as well as two non-acupoints. RESULTS: Before menstrual period, there was no significant difference in the surface blood perfusion of the acupoints between the dysmenorrhea group and the normal group (P>0.05). On the first day of menstruation, the surface blood perfusion of Xuanshu (GV 5), Mingmen (GV 4), Yaoyangguan (GV 3) and right Huangshu (KI 16) in the dysmenorrhea group was higher than that in the normal group (P<0.05, P<0.01). On the third day after menstruation, the surface blood perfusion of the right Henggu (KI 11) in the dysmenorrhea group was lower than that in the normal group (P<0.05). CONCLUSION In patients with primary dysmenorrhea, on the first day of menstruation, the surface blood perfusion of Xuanshu (GV 5), Mingmen (GV 4), Yaoyangguan (GV 3) of governor vessel, and the right Huangshu (KI 16) of thoroughfare vessel is increased, while on the third day after menstruation, the surface blood perfusion of the right Henggu (KI 11) of thoroughfare vessel is decreased. These findings might provide a basis for acupoint selection in the acupuncture-moxibustion treatment of primary dysmenorrhea.

The plant root-associated microbiomes include root microbiome and rhizosphere microbiome, which are closely related to plant life activities. Nearly 30% of photosynthesis products of plants are used to synthesize root compounds, there is evidence that root compounds regulate and significantly affect the root microbiome Tanshinones are the main hydrophobic components in Salvia miltiorrhiza. In order to study whether these compounds can regulate the root-associated microbiomes of S. miltiorrhiza, our study first identified a white root S. miltiorrhiza(BG) which contains little tanshinones. Retain of the fifth intron of tanshinones synthesis key enzyme gene SmCPS1 leading to the early termination of the SmCPS1 gene, and a stable white root phenotype. Further, wild type(WT) and BG were planted in greenhouse with nutrient soil(Pindstrup, Denmark) and Shandong soil(collected from the S. miltiorrhiza base in Weifang, Shandong), then high-throughput sequencing was used to analyze the root-associated microbiomes. The results showed that the tanshinones significantly affected the root-associated microbiomes of S. miltiorrhiza, and the impact on root microbiomes was more significant. There are significant differences between WT and BG root microbiomes in species richness, dominant strains and co-occurrence network. Tanshinones have a certain repelling effect on Bacilli which belongs to Gram-positive, while specifically attract some Gram-negative bacteria such as Betaproteobacteria and some specific genus of Alphaproteobacteria. This study determined the important role of tanshinones in regulating the structure of root-associated microbiomes from multiple angles, and shed a light for further improving the quality and yield of S. miltiorrhiza through microenvironment regulation.

Objective: The relationship between serum uric acid (SUA) levels and glycemic indices, including plasma glucose (FPG), 2-hour postload glucose (2h-PG), and glycated hemoglobin (HbA1c), remains inconclusive. We aimed to explore the associations between glycemic indices and SUA levels in the general Chinese population. Methods: The current study was a cross-sectional analysis using the first follow-up survey data from The China Cardiometabolic Disease and Cancer Cohort Study. A total of 105,922 community-dwelling adults aged ≥ 40 years underwent the oral glucose tolerance test and uric acid assessment. The nonlinear relationships between glycemic indices and SUA levels were explored using generalized additive models. Results: A total of 30,941 men and 62,361 women were eligible for the current analysis. Generalized additive models verified the inverted U-shaped association between glycemic indices and SUA levels, but with different inflection points in men and women. The thresholds for FPG, 2h-PG, and HbA1c for men and women were 6.5/8.0 mmol/L, 11.0/14.0 mmol/L, and 6.1/6.5, respectively (SUA levels increased with increasing glycemic indices before the inflection points and then eventually decreased with further increases in the glycemic indices). Conclusion An inverted U-shaped association was observed between major glycemic indices and uric acid levels in both sexes, while the inflection points were reached earlier in men than in women.

Parkinson disease (PD) is the second-most common neurodegenerative disorder. Its main pathological mechanism is the selective degeneration and deletion of dopaminergic neurons in the dense part of the substantia nigra and the damage of dopaminergic neurons caused by the abnormal deposition of a Lewy body, leading to a decreased dopamine level. Positron emission computed tomography (PET)/single photon emission computed tomography (SPECT) is a molecular imaging technology that can directly or indirectly reflect changes in molecular levels by using a specific tracer. With the research and development on the tracers of related enzymes for labeling dopamine transporter and dopamine receptor and for being involved in dopamine formation, this imaging technology has been applied to all aspects of PD research. It not only contributes to clinical work but also provides an important theoretical basis for exploring the pathological mechanism of PD at a molecular level. Therefore, this review discusses the application value of PET/SPECT in PD in terms of early diagnosis, disease severity evaluation, clinical manifestations, differential diagnosis, and pathological mechanism.

Coronavirus Disease 2019 (COVID-19), caused by a novel coronavirus (SARS-CoV-2), is a highly contagious disease. It firstly appeared in Wuhan, Hubei province of China in December 2019. During the next two months, it moved rapidly throughout China and spread to multiple countries through infected persons travelling by air. Most of the infected patients have mild symptoms including fever, fatigue and cough. But in severe cases, patients can progress rapidly and develop to the acute respiratory distress syndrome, septic shock, metabolic acidosis and coagulopathy. The new coronavirus was reported to spread via droplets, contact and natural aerosols from human-to-human. Therefore, high-risk aerosol-producing procedures such as endotracheal intubation may put the anesthesiologists at high risk of nosocomial infections. In fact, SARS-CoV-2 infection of anesthesiologists after endotracheal intubation for confirmed COVID-19 patients have been reported in hospitals in Wuhan. The expert panel of airway management in Chinese Society of Anaesthesiology has deliberated and drafted this recommendation, by which we hope to guide the performance of endotracheal intubation by frontline anesthesiologists and critical care physicians. During the airway management, enhanced droplet/airborne PPE should be applied to the health care providers. A good airway assessment before airway intervention is of vital importance. For patients with normal airway, awake intubation should be avoided and modified rapid sequence induction is strongly recommended. Sufficient muscle relaxant should be assured before intubation. For patients with difficult airway, good preparation of airway devices and detailed intubation plans should be made.

Objective To explore the protective effect of astragaloside Ⅳ on the oxidative stress injury of human glomerular mesangial cells under high glucose conditions and the mechanism.Methods The glomerular mesangial cells were dividedinto model group,control group and experimental-L/M/H groups.Model group was treated with 25 mmol · L-1 glucose,experimental-L/M/H groups were given 25,50,100 μmol · L-1 astragaloside Ⅳ on the basis of model group,control group was treated with equivalent normal saline.Each group was cultured for 48 h after inervention.The cells proliferation were detected by methyl thiazolyl tetrazolium (MTF),the reactive oxygen species (ROS) level and fluorescence intensity were detected by fluorescent probe method,the cells Akt/NF-κB signaling pathways related proteins were detected by Western blot.Results The proliferation inhibition rates of glomerular mesangial cells in experimental-L/M/H groups were (6.79 ± 0.12) ％,(17.05 ± 0.15) ％,(28.31 ± 0.23) ％,and increased with the increasing of astragaloside Ⅳ concentration(P ＜0.01).The ROS relative expressions of glomerular mesangial cells in control group,model group and experimental-L/M/H groups were 0.02 ± 0.01,0.07 ± 0.01,0.06 ± 0.02,0.04 ± 0.03,0.02 ± 0.02;the phospho-protein binases (p-Akt) protein relative expression were 0.25 ± 0.03,0.57 ± 0.02,0.46 ± 0.02,0.31 ± 0.04,0.27 ± 0.03;p-IκBαprotein relative expression were 0.44 ± 0.03,0.16 ±0.01,0.21 ±0.02,0.26 ±0.02,0.33 ±0.02.Compared with control group,the ROS relative expression,fluorescence intensity and p-Akt protein relative expression of model group increased significandy (P ＜ 0.01),the p-IκBα protein relative expression decreased significantly (P ＜0.01).Compared with model group,the ROS relative expression,fluorescence intensity and p-Akt protein relative expression of experimental groups decreased significantly with the increasing of astragaloside Ⅳ concentration (P ＜ 0.01);while the p-IκBα relative expression increased with the increasing of astragaloside Ⅳ concentration (P ＜ 0.01).Conclusion Astragaloside Ⅳ can adjust the ROS expression level of glomerular mesangial cells under high glucose conditions effectively,and inhibit the oxidative stress reaction,the action mechanism maybe related to the down-regulation of p-Akt protein and the up-regulation of p-IκBα protein of Akt/NF-κB signaling pathways,which has significant dose-dependent manner.

Salvia miltiorrhiza is a highly valued traditional chinese medicine for the treatment of atherosclerosis-related disorders in china, such as cardiovascular and cerebrovascular diseases in China. The wilt disease is serious in the culture of S. miltiorrhiza. Wilt disease cause biomass of plant shoots and roots is lessened, active components are decreased. To solve these problems, we research the pathogen causing wilt disease of S. miltiorrhiza. The suspected pathogen is identified by morphology and etiological test. The identification was further confirmed by alignment the sequences of internal transcribed spacer (ITS) amplified by PCR. Our result show the wilt disease of S. miltiorrhiza mostly occurred in July and August, which is hot and wetter. The wilt disease rate of S. miltiorrhiza continuous cropping for one year in S. miltiorrhiz stubble is 10%, but the wilt disease rate of S. miltiorrhiza continuous cropping for three years in S. miltiorrhiz stubble is 60%-70%. The root rot of S. miltiorrhiz caused by the wilt disease, so the wilt disease was mistaken for the rot root in production. Morphological characteristics show the pathogen is Fusarium oxysporum. The sequence of ITS wes determined and found by BLAST shared 99% identity to that of F. oxysporum f. sp. cucumerinum. So it comes to the conclusion that the causing agent of wilt disease on S. miltiorrhiza belongs to F. oxysporum.
