ObjectiveTo analyze the distribution characteristics of traditional Chinese medicine （TCM） syndrome elements in different risk populations of heart failure complicated with type 2 diabetes. MethodsClinical data of 675 type 2 diabetes patients were retrospectively collected. Lasso-multivariate Logistic regression was used to construct a clinical prediction nomogram model. Based on this， 441 non-heart failure patients were divided into a low-risk group （325 cases） and a high-risk group （116 cases） according to the median risk score of heart failure complicated with type 2 diabetes. TCM diagnostic information （four diagnostic methods） was collected for both groups， and factor analysis was applied to summarize the distribution of TCM syndrome elements in different risk populations. ResultsLasso-multivariate Logistic regression analysis identified age， disease duration， coronary heart disease， old myocardial infarction， arrhythmia， absolute neutrophil count， activated partial thromboplastin time， and α-hydroxybutyrate dehydrogenase as independent risk factors for heart failure complicated with type 2 diabetes. These were used as final predictive factors to construct the nomogram model. Model validation results showed that the area under the curve （AUC） of the receiver operating characteristic （ROC） curve for the modeling group and validation group were 0.934 and 0.935， respectively. The Hosmer-Lemeshow test （modeling group P = 0.996， validation group P = 0.121） indicated good model discrimination. Decision curve analysis showed that the curves for All and None crossed in the upper right corner， indicating high clinical utility. The low-risk and high-risk groups each obtained 14 common factors. Preliminary analysis revealed that the main disease elements in the low-risk group were qi deficiency （175 cases， 53.85%）， dampness （118 cases， 36.31%）， and heat （118 cases， 36.31%）， with the primary locations in the spleen （125 cases， 38.46%） and lungs （99 cases， 30.46%）. In the high-risk group， the main disease elements were yang deficiency （73 cases， 62.93%）， blood stasis （68 cases， 58.62%）， and heat （49 cases， 42.24%）， with the primary locations in the kidney （84 cases， 72.41%） and heart （70 cases， 60.34%）. ConclusionThe overall disease characteristics in different risk populations of type 2 diabetes patients with heart failure are a combination of deficiency and excess， with deficiency being predominant. Deficiency and heat are present throughout. The low-risk population mainly shows qi deficiency with dampness and heat， related to the spleen and lungs. The high-risk population shows yang deficiency with blood stasis and heat， related to the kidneys and heart.

ObjectiveTo observe the efficacy of Huoxue Jiedu Formulas （活血解毒方药， HJF） as an adjunctive treatement for patients with binding of stasis and toxin syndrome during the vulnerable period after acute myocardial infarction （AMI） percutaneous coronary intervention （PCI） surgery， and to explore its potential mechanism from the perspective of serum neutrophil extracellular traps （NETs）. MethodsA total of 129 patients with binding of stasis and toxin syndrome within 6 months after PCI for AMI were enrolled and divided into a treatment group （65 cases） and a control group （64 cases） based on patients' willingness to take Chinese herbal medicine. The control group received standard western medical therapy alone， while the treatment group additionally received HJF， one dose daily. Both groups were treated for four weeks. Before and after treatment， TCM syndrome scores were assessed. Seattle angina questionnaire （SAQ） was used to record angina stability and frequency scores， while the short form-36 health survey （SF-36） was employed to assess quality of life across eight dimensions， including physical functioning， role-physical， bodily pain， general health， vitality， social functioning， role-emotional， and mental health. The Pittsburgh sleep quality index （PSQI） was used to evaluate sleep quality， and the patient health questionnaire-15 （PHQ-15） was used to assess psychosomatic symptoms； Duke activity status index （DASI） was used to measure daily physical activity. Serum levels of neutrophil extracellular traps （NET） markers including myeloperoxidase-DNA （MPO-DNA）， neutrophil elastase-DNA （NE-DNA）， and citrullinated histone H3 （CitH3） were measured in 20 patients from the treatment group. ResultsAfter treatment， TCM syndrome score， PSQI score and PHQ-15 score in both groups significantly decreased， while DASI score， angina stability and frequency scores， and all eight dimensions of the SF-36 scale significantly increased （P＜0.05）. Compared to the control group， the treatment group had significantly lower TCM syndrome scores and significantly higher DASI， angina stability and frequency scores （P＜0.05）， as well as higher scores in the SF-36 dimensions of physical functioning， role-physical， social functioning， bodily pain， and vitality （P＜0.05）. After treatment， serum levels of MPO-DNA， CitH3， and NE-DNA in the treatment group were significantly reduced （P＜0.05）. ConclusionHJF combined with conventional therapy can significantly improve angina symptoms， TCM syndrome scores， and psychosomatic conditions in patients with binding of stasis and toxin syndrome during the vulnerable period after AMI. It also enhances quality of life， sleep quality， and daily physical activity. The underlying mechanism may be associated with the inhibition of serum NETs level.

ObjectiveTo observe the clinical efficacy and relative mechanism of the Modified Wenshen Yixin Formula （温肾益心方加减， MWYF） as an auxiliary treatment of coronary heart disease （CHD） complicated with hypothyroidism of spleen-kidney yang deficiency. MethodsA total of 135 CHD patients complicated with hypothyroidism and spleen-kidney yang deficiency were included and divided into control group （67 cases） and experimental group （68 cases） according to the patients' wishes of herbal medicine administration. The control group was given conventional western medicine， while the treatment group was additionally given MWYF， 1 dose per day； both groups were treated for 8 weeks. The traditional Chinese medicine （TCM） syndrome scores， angina scores， SF-36 scores， thyroid function indicators including thyroid stimulating hormone （TSH）， thyroxine （T4） and triiodothyronine （T3）， as well as serum cyclic adenosine monophosphate （cAMP）， cyclic guanosine monophosphate （cGMP）， monocyte chemoattractant ligand 2 （CCL2）， and tumor necrosis factor-related activator protein （CD40L） levels before and after treatment were compared between the two groups. The dosage and reduction and discontinuation rate of thyroid hormone preparations after treatment were compared between the two groups. The effectiveness regarding TCM syndrome and angina pectoris was evaluated， and the safety was assessed. ResultsBias was adjusted by matching on propensity score， and 102 cases were finally included in the statistical analysis， with 51 cases in each group. The total effective rate regarding TCM syndrome ［94.12% （48/51） versus 64.71% （33/51）］， the total effective rate regarding angina pectoris ［80.39% （41/51） versus 62.75% （32/51）］， and the reduction and discontinuation rate of thyroid hormone preparation ［39.21% （20/51） versus 5.88% （3/51）］ were significantly higher in the experimental group than those in the control group （P＜0.05 or P＜0.01）. After treatment， the total TCM syndrome score， individual scores of major symptoms ， the major symptoms score， the secondary symptoms score， angina pectoris score， and TSH level were significantly reduced （P＜0.01）， while all dimensions of SF-36 scores， T4， T3， and cAMP levels significantly increased in both groups （P＜0.05 or P＜0.01）. The dosage of thyroid hormone preparations and the levels of cGMP， CCL2， and CD40L in the experimental group significantly decreased after treatment （P＜0.01）. When compared between the two groups after treatment， the total TCM syndrome score， the major symptoms score， the scores of individual major symptom （chest tightness， chest pain， fear of cold， cold limbs， waist and kness soreness and weakness）， the secondary symptoms score， angina pectoris score， TSH， cGMP， CCL2， and CD40L levels of the experimental group were significantly lower than those of the control group （P＜0.05 or P＜0.01）， while all dimension scores of SF-36， T4， T3， and cAMP levels were significantly higher （P＜0.01）. A total of three adverse events occurred during treatment， none of which were judged to be related to the interventions of this study. ConclusionMWYF can significantly ameliorate the TCM syndrome， angina pectoris， quality of life and thyroid function in CHD patients complicated with hypothyroidism and spleen-kidney yang deficiency， and can promote the reduction and disconti-nuation of thyroid hormone preparations. The mechanism may be related to the regulation of cAMP/cGMP balance， the regulation of hypothalamic-pituitary-thyroid metabolic axis and the reduction of immune inflammation.

Cognitive dysfunction refers to dysfunction of individual perception,memory,understanding,learning,creation and other dysfunctions caused by abnormal brain function and structure.Based on the fact that the spleen can't regulate transportation and transformation,govern blood and send up essential substance,combined with the microbiota-gut-brain axis,this article discussed the etiology and pathogenesis of intestinal flora imbalance affecting cognitive dysfunction in TCM.It was proposed that the spleen in TCM and intestinal flora are connected in physiology and pathology:the spleen regulates spirit and governs cognition,when the spleen fails to function normally that it can't dominate transportation and transformation,govern blood and send up essential substance will cause that the brain spirit can not be nourished;intestinal flora is closely related to the spleen in TCM,and affects brain function through the nervous system,endocrine,immune and metabolic mechanisms.This article can provide explore new ideas for the clinical research and treatment of cognitive dysfunction of traditional Chinese and Western medicine.

OBJECTIVE To explore whether Yinjia tablets improve infertility in rats with chronic salpingitis by correcting the peripheral blood Th17/Treg balance. METHODS One hundred female Wistar rats, 82 of which were constructed as a rat model of chronic salpingitis. After successful modeling, the rats were randomly divided into model group, levofloxacin group (20 mg·kg-1), low-dose Yinjia tablets group(0.38 g·kg-1·d-1), medium-dose Yinjia tablets group(0.76 g·kg-1·d-1) and high-dose Yinjia tablets group(1.52 g·kg-1·d-1), 16 rats in each group, and other 16 rats were set up as control group. The treatment groups were administered by gavage at different doses, and the model group and the control group were given the same amount of saline(20 mL·kg-1·d-1), once a day. The gavage was stopped for 1 d after 7 d, and 7 d was one cycle, with a total of 3 cycles of gavage. After administration, the rats were observed for conception and blood samples and oviductal tissues were collected. HE staining was used to observe the pathological changes of fallopian tube tissues; transmission electron microscopy was used to observe the ultrastructural changes of fallopian tube tissues; ELISA was used to detect TNF-α and IL-6 in serum; flow cytometry was used to detect the ratio of Treg and Th17 cells in peripheral blood; RT-qPCR and Western blotting were used to detect IL-17, IL-10, Foxp3, RORγt mRNA and protein expression. RESULTS Compared with the control group, the cilia and microvilli in the model group were sparse and the mitochondria were swollen; the TNF-α and IL-6 contents, the proportion of Th17 cells, and the expression of IL-17 and RORγt mRNA and protein in the oviduct tissues were significantly higher, and the fertility rate, IL-10, the proportion of Treg cells, and the expression of Foxp3 mRNA and protein in the rats were significantly lower(P<0.05). Compared with the model group, the high-dose group of Yinjia tablets improved the structure of oviduct of rats; significantly reduced the TNF-α, IL-6 content, Th17 cell proportion and IL-17, RORγt mRNA and protein expression in oviduct tissue of model rats; and significantly increased the conception rate and IL-10, Treg cell proportion and Foxp3 mRNA and protein expression of rats(P<0.05). CONCLUSION Yinjia tablets can effectively regulate Th17/Treg balance, which in turn regulates Treg and Th17 cell-mediated inflammatory responses and improves the conception rate in chronic salpingitis rats.

Objective: To investigate the incidence of complications following minimal invasive subcutaneous internal fixator (INFIX) for the treatment of anterior pelvic ring instability, and to analyze control measures. Methods: Data of 42 patients with anterior pelvic ring instability who were treated by anterior subcutaneous internal fixation in our hospital from January 2016 to December 2017 were retrospectively analyzed. There were 15 females and 27 males with an average age of 45.4 years (range, 18-67 years). There were 26 traffic injuries, 10 falling injuries, 3 crush injuries and 3 low energy injuries. According to Tile classification, 24 cases of B2 type, 16 cases of B3 type, 1 case of C1 type and 1 case of C2 type. According to Young-Burgess classification, there were 20 cases of LCI, 18 cases of LCII, 1 case of LCIII, 1 case of APCI, 1 case of APCII, and 1 case of VS. Fourteen cases were combined with limb fractures, and 11 cases were combined with thoracic or abdominal injuries requiring surgical treatment, while 16 cases were with brain injuries. For type APC2, LC1, and some LC2 fractures, fixation for the anterior pelvic ring is enough with INFIX technique alone. For some LC2, LC3, or VS fractures, the anterior and posterior ring were both fixed. Postoperative reduction was evaluated by Matta radiological criteria. Lateral thigh numbness and pain, quadriceps muscle power were recorded during follow-up, and clinical efficacy was evaluated by Majeed score at 6 months after operation. Results: All the 42 patients were followed up for 6 to 12 months, with an average of 9.3 months. Matta standard evaluation for fracture reduction showed that 28 cases were excellent, 14 cases good, and the excellent and good rate was 100%. The early complication rate (within 3 month after operation) was 23.8% (10/42) including 6 cases of lateral femoral cutaneous nerve injury and 2 cases of femoral nerve injury. The symptoms were obviously relieved after the treatment of nutrient nerve and hyperbaric oxygen; 1 case had incision infection which was healed after anti-infection therapy and internal plant removal; 1 case suffered from superior gluteal artery injury which was controlled by pressure hemostasis. Six months after surgery, no case had lost reduction. At 6 months follow-up, the Majeed score was 72-96, with an average of 84.96, of which 32 were excellent and 10 were good, thus the excellent and good rate was 100% (42/42). Conclusion INFIX is an effective internal fixation method for the treatment of unstable anterior pelvic ring injury. However, it has a high rate of early complications, among which nerve injury has the highest incidence.

Objective: To isolate, purify and culture fibroblastic reticular cells (FRCs) of mouse in spleen, to develop a reliable and robust method to immortalize primary mouse FRCs, to filter stable FRCs cell lines, to prove that the clones can be infected by SFTSV in vitro. Methods: After purifying FRCs by fluorescence activated cell sorting (FACS) from autoMACS-enriched stroma cells of mouse spleen, we infected FRCs by simian virus 40 large T antigen in vitro, screened the FRCs clones with puromycin, compared primary and immortalized FRCs by RNA sequencing(RNA-seq) technology, infected the clones with severe fever with thrombocytopenia syndrome virus (SFTSV) in vitro. Results: We succeed in culturing purified FRCs from spleen, isolated four stable FRCs clones, two of which have a purity of 99%, survived for more than 50 passages, express the key FRCs marker podoplanin and do not express CD31 and CD45. Clone 01 lost the typical FRCs-like morphology, the rate of expansion of which is quite different from that of primary FRCs and Clone 02. Clone 02 can be infected with SFTSV, which has the same gene expression pattern and immunophenotype with primary FRCs. Conclusions The stable FRCs clone Clone 02 has FRCs-like morphology and express key FRCs surface markers podoplanin (GP38 or PDPN) and do not express endothelial cell markers CD31 and leukocyte common antigen CD45. The RNA expression profiles identified by RNA-seq are also characteristic of FRCs. Infected with SFTSV in vitro, Clone 02 will be a new platform to study SFTSV.
