It is believed that the root cause of vascular dementia lies in insufficient primal yang and weakness in the circulation of blood. The key pathological factors are the mutual stagnation of phlegm and blood stasis， and the obstruction of blood vessels. The general treatment principle is to tonify qi and promote yang， expel pathogenic factors， and unblock yang. This involves supplementing the innate and acquired yang qi of the spleen and kidneys， removing pathogenic factors like phlegm， turbidity， and blood stasis， in order to restore the function of yang qi and promote the circulation of blood and qi. The basic prescription for tonifying qi and promoting yang includes Heishunpian （Lycium Ruthenicum）， Zhichuanwu （Aconitum Carmichaelii）， Guizhi （Cinnamomum Cassia）， Renshen （Panax Ginseng）， and Huangqi （Astragalus Membranaceus）. Depending on the type of pathogenic excess， the treatment can be modified with Tongqiao Huoxue Decoction （通窍活血汤）， adding Yujin （Curcuma Longa） and Xiangfu （Cyperus Rotundus） to invigorate blood and promote yang， or with Fabanxia （Pinellia Ternata）， Chenpi （Citrus Reticulata）， Zhishi （Citrus Aurantium） plus Sijunzi Decoction （四君子汤） to resolve phlegm and promote yang. Both the root and branch are treated simultaneously. When yang qi is activated， blood and qi are nourished， and when pathogenic excess is expelled， the blood vessels are unblocked. This approach aims to provide a treatment strategy for vascular dementia.

Objective:To investigate the distribution rules of artemisia pollen and the clinical sensitization characteristics of allergic rhinitis (AR) induced by artemisia pollen in three urban and rural areas of Inner Mongolia.Methods:From March to October 2019, in 3 central cities (Chifeng, Hohhot, Ordos) and rural areas of Inner Mongolia, an epidemiological investigation method combining multi-stage stratified random sampling and face-to-face questionnaire survey was adopted to screen suspected AR patients, and skin prick test (SPT) was applied for diagnosis. At the same time, pollen monitoring was carried out in 3 areas to analyze the distribution and clinical sensitization characteristics of artemisia pollen.SPSS26.0 statistical software was used to process all the data. Chi-square test was used to compare rates among different age, sex, region and nationality, Spearman test was used to describe correlation analysis, and pairwise comparison of positive rates among multiple samples was used Bonferroni method.Results:Among the 6 393 subjects, 1 093 cases were diagnosed with AR, and the prevalence of AR was 17.10% (1 093/6 393). Among them, pollen-induced allergic rhinitis, the prevalence of PiAR was 10.97% (701/6 393), accounting for 64.14%(701/1 093).The highest incidence was in the youth group (20-39 years old), accounting for 46.94% (329/701).The diagnosed prevalence was higher in females than in males (11.35% vs. 10.64%, χ2 value 12.304, P<0.001).The prevalence rate of ethnic minority was higher than that of Han nationality (13.01% vs. 10.65%, χ2 value 6.296, P=0.008).The prevalence in urban areas was also significantly higher than that in rural areas (18.40% vs. 5.50%, χ2 value 10.497, P<0.001).There was significant difference in prevalence rate among the three regions in Inner Mongolia (6.06% in Chifeng, 13.46% in Hohhot, 16.39% in Ordos, χ2 value 70.054, P<0.001).The main clinical symptoms of artemisia PiAR were sneezing (95.58%), nasal congestion (91.73%) and nasal itching (89.30%).Allergic conjunctivitis accounted for 79.60% (558/701), chronic sinusitis for 55.63% (390/701), asthma for 23.25% (163/701).The pattern of artemisia pollen sensitization was mainly multiple sensitization, and the frequency of clinical symptoms and clinical diseases induced by hypersensitization with other allergens accounted for more than that caused by single artemisia pollen. The spread period of Artemisia pollen in the three regions was from June to October, and the peak state was in August in summer. The peak time of clinical symptoms in artemisia PiAR patients was about 2 weeks earlier than the peak time of pollen concentration, and the two were significantly positively correlated ( R=0.7671, P<0.001). Conclusion:Artemisia pollens are the dominant pollens in late summer and early autumn in Inner Mongolia, and the prevalence of artemisia PiAR is high. Controlling the spread of Artemisia pollens is of great significance for the prevention and treatment of AR.

The gut microbiota is a vast microbial ecosystem,specifically present in the organism and plays an important regulatory role in the body's health or disease state together with its metabolites.After spinal cord injury,the complex pathophysiology at the site of trauma makes axonal regeneration difficult,and the autonomic motor dysfunction induced by spinal cord injury disrupts gastrointestinal function and causes gut microbiota imbalance.The previous clinical outcomes of neurorepair strategies after spinal cord injury have not been ideal.The dysregulated gut microbiota and neuroinflammation after spinal cord injury are closely associated with the prognosis of the patients.The potential mechanisms by which the gut microbiota may influence the neuroinflammation after spinal cord injury may include the activation of gut-associated lymphoid tissue and disruption of the intestinal barrier by the imbalanced microbiota,and gut microbiota and its metabolites such as lipopolysaccharides(LPS),short chain fatty acids(SCFAs),5-hydroxytryptamine(5-HT),and tryptophan,as well as immune cells,inflammatory factors,and neurotransmitters the local inflammatory response in the spinal cord through the circulatory system.This paper revews the studies on the changes in gut microbiota after spinal cord injury and their effects on the spinal cord neuroinflammation,providing new targets and new ideas for improving the neuroinflammation after spinal cord injury.

Objective To investigate the protective effects and underlying mechanisms of sodium butyrate on rats exposed to hypoxia and cold conditions.Methods Fifty-eight male SD rats (aged 7～8 weeks,weighing 240～260 g ) were randomly divided into normoxia normothermia saline control (NNC ) group (n=10),normoxia normothermia sodium butyrate(NNB)group(n=10),hypoxia cold saline control (HCC) group (n=19),and hypoxia cold sodium butyrate (HCB)group (n=19).The intragastric dose of sodium butyrate was 200 mg/kg for the NNB and HCB groups,while the NNC and HCC groups were given normal saline of 5 mL/kg.①After continuous intragastric administration for 7 d,the rats in the HCC and HCB groups were placed in a low-pressure hypoxic chamber to simulate an altitude of 5000 m and exposed to a temperature of 8 ℃ for 7 d.Subsequently,blood samples were collected from the abdominal aorta for blood gas analysis,blood routine test,and detection for serum biochemical indicators.ELISA was used to determine serum inflammatory cytokines and endocrine hormones.The rats in the NNC and NNB groups(n=10)were fed outside the chamber and underwent the same tests in 7 d later to evaluate the protective effects of sodium butyrate on the body.②Core body temperature monitoring was conducted to assess the impact of sodium butyrate on the rmoregulation in rats exposed to hypoxia and cold(n=3).③Hypoxia exercise tolerance of the HCC group and HCB group in a hypoxic chamber (11％O2 )was evaluated for their hypoxia resistance (n=6).Results Compared to the NNC group,the rats in the HCC group exhibited significant decreases in arterial oxygen saturation (SaO2 )and arterial oxygen partial pressure (PaO2 ),serum levels of IL-4,estradiol (E2)and cortisol (F),core temperature,and exercise duration (P<0.05),and had notably increased levels of red blood cell (RBC)count,hemoglobin (HGB),hematocrit (HCT),cardiac troponin (CRDAC-T),uric acid (UA),alanine aminotransferase (ALT),total cholesterol (TC),low-density lipoprotein (LDL),IL-6 and granulocyte-macrophage colony-stimulating factor (GM-CSF)(P<0.05).Compared to the HCC group,the rats in the HCB group exhibited significant increases in SaO2,PaO2,IL-4,E2,F,corticotropin releasing hormone (CRH)and adrenocorticotropic hormone (ACTH)(P<0.05),remarkably longer exercise duration under hypoxic exposure (P<0.05 ),but decreases in RBC count,serum levels of HGB,HCT,CRDAC-T,UA,ALT,TC,LDL,IL-6,GM-CSF and free thyroxine (FT4 ),and core temperature (P<0.05).Conclusion Sodium butyrate exhibits protective effects on rats exposed to hypoxia and cold conditions,and it is helpful in their adaptation to these hypoxia and cold environments.

Patients with spinal cord injury is associated with seriously affected gastrointestinal function and imbalance of intestinal flora, leading to increased inflammation of spinal cord nerves. With the proposal of the theory of gut microbiota-gut-brain axis in recent years, the regulatory role of gut microbiota in the central nervous system and gastrointestinal system has gradually attracted attention. Although a considerable number of studies have focused on the effects of intestinal flora characteristics on spinal cord nerve function repair in patients with spinal cord injury from different perspectives, there are numerous research models for treating spinal cord injury with intestinal flora as intervention targets and remains a lack of unified and effective clinical treatment methods. In this paper, the authors review the research progress in characteristics of intestinal microflora and intestinal microflora-targeted therapeutic methods in patients with spinal cord injury, hoping to provide a reference for the clinical treatment and basic research of spinal cord injury.

Radiation pneumonia is a side effect that cannot be ignored in the current radiation therapy for lung cancer. At present, there are studies and reports of the introduction of functional imaging technology into lung cancer radiotherapy plans, in which 4DCT has better application prospects in radiotherapy for lung cancer because of its advantages of simple operation, high spatial resolution and no additional cost, etc. Compared with single-photon emission computed tomography (SPECT)-CT, positron emission tomography (PET)-CT, MRI has a better application prospect in radiotherapy of lung cancer. The use of 4DCT to obtain the patient's lung function status can predict radiation pulmonary toxicity and assist clinicians to deliver prompt interventions. Moreover, it can help carry out radiotherapy for functional lung avoidance, mitigate the damage of normal lung tissues, and alleviate chest toxicity, which may have wider application value in the future. In this article, research progress on functional lung imaging algorithms based on 4DCT and the application of radiation therapy for lung cancer was reviewed.

BACKGROUND: Gestational diabetes mellitus (GDM) brings health issues for both mothers and offspring, and GDM prevention is as important as GDM management. It was shown that a history of GDM was significantly associated with a higher maternal risk for GDM recurrence. The incidence of GDM recurrence was unclear because of the incidence of second-child was low before 2016 in China. We aim to investigate the prevalence of GDM recurrence and its associated high-risk factors which may be useful for the prediction of GDM recurrence in China. METHODS: A retrospective study was conducted which enrolled participants who underwent regular prenatal examination and delivered twice in the same hospital of 18 research centers. All participants were enrolled from January 2018 to October 2018, where they delivered the second baby during this period. A total of 6204 women were enrolled in this study, and 1002 women with a history of GDM were analyzed further. All participants enrolled in the study had an oral glucose tolerance test (OGTT) result at 24 to 28 weeks and were diagnosed as GDM in the first pregnancy according to the OGTT value (when any one of the following values is met or exceeded to the 75-g OGTT: 0 h [fasting], ≥5.10 mmol/L; 1 h, ≥10.00 mmol/L; and 2 h, ≥8.50 mmol/L). The prevalence of GDM recurrence and development of type 2 diabetes mellitus were calculated, and its related risk factors were analyzed. RESULTS: In 6204 participants, there are 1002 women (1002/6204,16.15%) with a history of GDM and 5202 women (5202/6204, 83.85%) without a history of GDM. There are significant differences in age (32.43 ± 4.03 years vs. 33.00 ± 3.34 years vs. 32.19 ± 3.37 years, P  < 0.001), pregnancy interval (4.06 ± 1.44 years vs. 3.52 ± 1.43 years vs. 3.38 ± 1.35 years, P  = 0.004), prepregnancy body mass index (BMI) (27.40 ± 4.62 kg/m2vs. 23.50 ± 3.52 kg/m2vs. 22.55 ± 3.47 kg/m2, P < 0.001), history of delivered macrosomia (22.7% vs. 11.0% vs. 6.2%, P < 0.001) among the development of diabetes mellitus (DM), recurrence of GDM, and normal women. Moreover, it seems so important in the degree of abnormal glucose metabolism in the first pregnancy to the recurrence of GDM and the development of DM. There are significant differences in OGTT levels of the first pregnancy such as area under the curve of OGTT value (18.31 ± 1.90 mmol/L vs. 16.27 ± 1.93 mmol/L vs. 15.55 ± 1.92 mmol/L, P < 0.001), OGTT fasting value (5.43 ± 0.48 mmol/L vs. 5.16 ± 0.49 mmol/L vs. 5.02 ± 0.47 mmol/L, P < 0.001), OGTT 1-hour value (10.93 ± 1.34 mmol/L vs. 9.69 ± 1.53 mmol/L vs. 9.15 ± 1.58 mmol/L, P < 0.001), OGTT 2-hour value (9.30 ± 1.66 mmol/L vs. 8.01 ± 1.32 mmol/L vs. 7.79 ± 1.38 mmol/L, P < 0.001), incidence of impaired fasting glucose (IFG) (fasting plasma glucose ≥5.6 mmol/L) (31.3% vs. 14.6% vs. 8.8%, P < 0.001), and incidence of two or more abnormal OGTT values (68.8% vs. 39.7% vs. 23.9%, P < 0.001) among the three groups. Using multivariate analysis, the factors, such as age (1.07 [1.02-1.12], P = 0.006), prepregnancy BMI (1.07 [1.02, 1.12], P  = 0.003), and area under the curve of OGTT in the first pregnancy (1.14 [1.02, 1.26], P  = 0.02), have an effect on maternal GDM recurrence; the factors, such as age (1.28 [1.01-1.61], P  = 0.04), pre-pregnancy BMI (1.26 [1.04, 1.53], P = 0.02), and area under the curve of OGTT in the first pregnancy (1.65 [1.04, 2.62], P = 0.03), have an effect on maternal DM developed further. CONCLUSIONS The history of GDM was significantly associated with a higher maternal risk for GDM recurrence during follow-up after the first pregnancy. The associated risk factors for GDM recurrence or development of DM include age, high pre-pregnancy BMI, history of delivered macrosomia, the OGTT level in the first pregnancy, such as the high area under the curve of OGTT, IFG, and two or more abnormal OGTT values. To prevent GDM recurrence, women with a history of GDM should do the preconception counseling before preparing next pregnancy.

Acupuncture can improve the motor and non-motor symptoms of Parkinson's disease, and the effect of acupuncture combined with drug therapy is better than that of drug therapy alone. The possible mechanism includes inhibiting α-synuclein aggregation, oxidative stress, and neuroinflammation, inhibiting the apoptosis of dopaminergic neurons, and achieving a neuroprotective effect. The points mainly selected for Acupuncture treatment for this disease are Zusanli (ST 36), Yanglingquan (GB 34), Taichong (LR 3), Xuehai (SP 10), and other points. Early use of acupuncture and acupuncture combined with medical treatment strategy is worthy of clinical application.

Objective:To explore the effects of interpregnancy interval (IPI) on pregnancy outcomes of subsequent pregnancy.Methods:A multicenter retrospective study was conducted in 21 hospitals in China. Information of age, height, pre-pregnancy weight, IPI, history of diseases, complications of pregnancy, gestational age of delivery, delivery mode, and pregnancy outcomes of the participants were collected by consulting medical records of pregnant women who had two consecutive deliveries in the same hospital during 2011 to 2018. The participants were divided into 4 groups according to IPI:<18 months, 18-23 months, 24-59 months and ≥60 months. According to the WHO′s recommendation, with the IPI of 24-59 months group as a reference, to the effects of IPI on pregnancy outcomes of subsequent pregnancy were analyzed. Stratified analysis was further carried out based on age, history of gestational diabetes mellitus (GDM), macrosomia, and premature delivery, to explore the differences in the effects of IPI on pregnancy outcomes among women with different characteristics.Results:A total of 8 026 women were included in this study. There were 423, 623, 5 512 and 1 468 participants in <18 months group, 18-23 months group, 24-59 months group and ≥60 months group, respectively. (1) The age, pre-pregnancy body mass index (BMI), history of cesarean section, GDM, gestational hypertension and cesarean section delivery rate of <18 months group, 18-23 months group, 24-59 months group and ≥60 months group were gradually increased, and the differences were statistically significant ( P<0.05). (2) After adjusting for potential confounding factors, compared with women in the IPI of 24-59 months group, the risk of premature delivery, premature rupture of membranes, and oligohydramnios were increased by 42% ( OR=1.42, 95% CI: 1.07-1.88, P=0.015), 46% ( OR=1.46, 95% CI: 1.13-1.88, P=0.004), and 64% ( OR=1.64, 95% CI: 1.13-2.38, P=0.009) respectively for women in the IPI≥60 months group. No effects of IPI on other pregnancy outcomes were found in this study ( P>0.05). (3) After stratified by age and adjusted for confounding factors, compared with women in the IPI of 24-59 months group, IPI≥60 months would significantly increase the risk of oligohydramnios for women with advanced age ( OR=2.87, 95% CI: 1.41-5.83, P=0.004); and <18 months could increase the risk of premature rupture of membranes for women under the age of 35 ( OR=1.59, 95% CI: 1.04-2.43, P=0.032). Both the risk of premature rupture of membranes ( OR=1.58, 95% CI: 1.18-2.13, P=0.002) and premature delivery ( OR=1.52, 95% CI: 1.07-2.17, P=0.020) were significantly increased in the IPI≥60 months group. After stratified by history of GDM and adjusted for confounding factors, compared with women in the IPI of 24-59 months group, IPI≥60 months would lead to an increased risk of postpartum hemorrhage for women with a history of GDM ( OR=5.34, 95% CI: 1.45-19.70, P=0.012) and an increased risk of premature rupture of membranes for women without a history of GDM ( OR=1.44, 95% CI: 1.10-1.90, P=0.009). After stratified by history of macrosomia and adjusted for confounding factors, compared with women in the IPI of 24-59 months group, IPI≥60 months could increase the proportion of cesarean section for women with a history of macrosomia ( OR=4.11, 95% CI: 1.18-14.27, P=0.026) and the risk of premature rupture of membranes for women without a history of macrosomia ( OR=1.46, 95% CI: 1.12-1.89, P=0.005). After stratified by history of premature delivery and adjusted for confounding factors, compared with women in the IPI of 24-59 months group, IPI≥60 months would significantly increase the risk of premature rupture of membranes for women without a history of premature delivery ( OR=1.47, 95% CI: 1.13-1.92, P=0.004). Conclusions:Both IPI≥60 months and <18 months would increase the risk of adverse pregnancy outcomes in the subsequent pregnancy. Healthcare education and consultation should be conducted for women of reproductive age to maintain an appropriate IPI when they plan to pregnant again, to reduce the risk of adverse pregnancy outcomes in the subsequent pregnancy.
