Based on the analysis of the relevant records of the contralateral bloodletting technique, it is believed that this needling technique has 3 key characteristics, including "contralateral selection of points", "points on the four extremities dominated" and "collaterals selected rather than meridian points". Through the studies on philology and the annotation by the doctors in the past dynasties, a part of point prescriptions for the contralateral bloodletting is investigated, and those not belonged to the category of this needling technique in Suwen: Miuci Lun (On Contralateral Bloodletting) are distinguished. It is concluded that the failure of consensus-making in classifying point prescriptions is due to the lack of understanding on the characteristics of contralateral bloodletting and the misunderstanding on the errors of sentences and words. It is suggested that the study on theoretic concepts should lay on the problems relevant with the generalization and alienation of concepts. The mode of "combination of the detail with the whole" should be adopted. It starts from grasping the overall by systematic review, and followed by deliberating in details, so as to correctly identify the original concept and connotation.

Eight new diterpenoids, Isodons A-H (1-8), comprising seco-abietane and abietane-type structures, together with 13 known analogues (9-21), were isolated from Isodon lophanthoides (Buch.-Ham. ex D. Don) Hara. The compounds (+)-3/(-)-3, (+)-4/(-)-4, and (+)-5/(-)-5 were identified as three enantiomeric pairs. The planar structures and absolute configurations of 1-8 were determined through high-resolution electrospray ionization mass spectrometry (HR-ESI-MS), 1D & 2D nuclear magnetic resonance (NMR) spectroscopy, electronic circular dichroism (ECD) calculations, and X-ray diffraction crystallography. A cholesterol 7α-hydroxylase (Cyp7a1) luciferase reporter assay revealed significant anti-cholestatic activities for compounds 1, (+)-4, 6, 7, 12-14, and 16. Additionally, compound 6 demonstrated anti-cholestatic effects through the farnesoid X receptor (FXR)-associated signaling pathways in vitro and in vivo. These findings suggest potential applications for I. Lophanthoides in pharmaceutical development.

Fetal heart rate plays an essential role in maternal and fetal monitoring and fetal health detection. In this study, a method based on Poincare Plot and LSTM is proposed to realize the high performance classification of abnormal fetal heart rate. Firstly, the original fetal heart rate signal of CTU-UHB database is preprocessed via interpolation, then the sequential fetal heart rate signal is converted into Poincare Plot to obtain nonlinear characteristics of the signals, and then SquenzeNet is used to extract the features of Poincare Plot. Finally, the features extracted by SqueezeNet are classified by LSTM. And the accuracy, the true positive rate and the false positive rate are 98.00%, 100.00%, 92.30% respectively on 2 000 test set data. Compared with the traditional fetal heart rate classification method, all respects are improved. The method proposed in this study has good performance in CTU-UHB fetal monitoring database and has certain practical value in the clinical diagnosis of auxiliary fetal heart rate detection.

Toxoplasma gondii, an intracellular protozoan parasite that infects one-third of the world’s population, has been reported to hijack host cell apoptotic machinery and promote either an anti- or proapoptotic program depending on the parasite virulence and load and the host cell type. However, little is known about the regulation of human FHs 74 small intestinal epithelial cell viability in response to T. gondii infection. Here we show that T. gondii RH strain tachyzoite infection or ESP treatment of FHs 74 Int cells induced apoptosis, mitochondrial dysfunction and ER stress in host cells. Pretreatment with 4-PBA inhibited the expression or activation of key molecules involved in ER stress. In addition, both T. gondii and ESP challenge-induced mitochondrial dysfunction and cell death were dramatically suppressed in 4-PBA pretreated cells. Our study indicates that T. gondii infection induced ER stress in FHs 74 Int cells, which induced mitochondrial dysfunction followed by apoptosis. This may constitute a potential molecular mechanism responsible for the foodborne parasitic disease caused by T. gondii.

Toxoplasma gondii is an intracellular parasite that causes severe disease when the infection occurs during pregnancy. Adenosine is a purine nucleoside involved in numerous physiological processes; however, the role of adenosine receptors in T. gondii-induced trophoblast cell function has not been investigated until now. The goal of the present study was to evaluate the intracellular signaling pathways regulated by adenosine receptors using a HTR-8/SVneo trophoblast cell model of T. gondii infection. HTR8/SVneo human extravillous trophoblast cells were infected with or without T. gondii and then evaluated for cell morphology, intracellular proliferation of the parasite, adenosine receptor expression, TNF-α production and mitogen-activated protein (MAP) kinase signaling pathways triggered by adenosine A3 receptor (A3AR). HTR8/SVneo cells infected with T. gondii exhibited an altered cytoskeletal changes, an increased infection rate and reduced viability in an infection time-dependent manner. T. gondii significantly promoted increased TNF-α production, A3AR protein levels and p38, ERK1/2 and JNK phosphorylation compared to those observed in uninfected control cells. Moreover, the inhibition of A3AR by A3AR siRNA transfection apparently suppressed the T. gondii infection-mediated upregulation of TNF-α, A3AR production and MAPK activation. In addition, T. gondii-promoted TNF-α secretion was dramatically attenuated by pretreatment with PD098059 or SP600125. These results indicate that A3AR-mediated activation of ERK1/2 and JNK positively regulates TNF-α secretion in T. gondii-infected HTR8/SVneo cells.

The discovery and application of Lanwei (EX-LE 7) was reviewed to elaborate its enlightenment on the inheritance and innovation of acupuncture. Literature published before April of 2017 was searched in CNKI and VIP database with"Lanwei (EX-LE 7)"and"acupuncture"as key words. Related references and publications were retrieved. According to the purpose, literature was screened and key information was extracted to perform systematic review and analysis. The results indicated Lanwei (EX-LE 7), reflection of relationship between organ and body surface under the guidance of acupuncture and meridians theory, was not a point, but an area.

BACKGROUND:Perioperative high hidden blood loss affects the recovery of joint function after total hip replacement. OBJECTIVE:To analyze the reliability of the Mini Nutritional Assessment on evaluating the nutritional status in elderly patients with femoral neck fracture on admission, and to investigate the effect of nutritional status variation on hidden blood loss after total hip replacement. METHODS:234 elderly patients with femoral neck fracture underwent total hip replacement. By using Mini Nutritional Assessment, patients were randomly divided into three groups:wel-nourishment group (n=52), malnourishment at risk group (n=92), and malnourishment group (n=90). The results were used to analyze the correlation of Mini Nutritional Assessment and serological nutrition indicators, and to hidden blood loss. RESULTS AND CONCLUSION:(1) Hidden blood loss:101 patients suffered from high hidden blood loss. Hidden blood loss, its proportion to total blood loss and incidence of high hidden blood loss gradual y increased with the deterioration of the nutritional status (P<0.05). (2) Mini Nutritional Assessment:Pre-operative Mini Nutritional Assessment score, and the incidence of hidden blood loss evaluated by albumin, prealbumin, transferrin, lymphocyte count, the percentage of lymphocytes and hemoglobin was significantly higher in patients with high hidden blood loss than those with low hidden blood loss (P<0.01). (3) Results of correlation analysis:High hidden blood loss was positively correlated with pre-operative Mini Nutritional Assessment, albumin, prealbumin, transferrin, the percentage of lymphocytes and hemoglobin (P<0.05). (4) These findings confirm that risk evaluation with Mini Nutritional Assessment is a reliable method to assess the nutritional status in elderly patients undergoing total hip replacement. Its combination with various serum nutrition indicators can determine high hidden blood loss and the prognosis.

Objective To investigate the clinical effect of dysmenorrhea in patients with adenomyosis treated by high intensity focused ultrasound (HIFU) ablation combined with gonadotropin-releasing hormone agonist (GnRH-a) and levonorgestrel-releasing intrauterine system (LNG-IUS). Methods From April 2012 to December 2015, 477 cases of adenomyosis patients with dysmenorrhea were treated by HIFU in the Third Xiangya Hospital. Among them, some patients were treated with HIFU alone, some of them were treated with HIFU combined with GnRH-a and (or) LNG-IUS, thus were classified as H group, H+G group, H+M group and H+G+M group. The improvements of clinical results were compared among the four groups and the influencing factors of HIFU treatment for adenomyosis were also analyzed. Results During the follow-up period, the overall effective rates of the treatment decreased with time, 3 months 89.4% (345/386), 12 months 84.0%(221/263), 24 months 74.2%(98/132), and the overall recurrence rate was 12.9%(39/303). The significant difference in the curative at 3 months [H group 83.7%(170/203), H+M group 95.0%(95/100), H+G group 100.0%(43/43), H+G+M group 96.8%(30/31)], 12 months [H group 79.4%(123/155), H+M group 93.2%(69/74), H+G group 11/12, H+G+M group 15/17], and 24 months [H group 68.0%(51/75), H+M group 96.4% (27/28), H+G group 6/12, H+G+M group 15/15] after HIFU treatment and recurrence rate [H group 19.0%(29/153), H+M group 3.3%(3/90), H+G group 19.4%(6/31), H+G+M group 4.5%(1/22)] were observed among the four groups (P<0.05). Pairwise comparison further showed that, in 3 months after the treatment, the effect of H group was significantly lower than those of H+M group and H+G group (P=0.003, P=0.005);in 12 months after the treatment, the effect of H group was significantly lower than that of H+M group (P=0.006);while in 24 months after treatment, the effect of H group was significantly lower than that of H+G+M group (P=0.005), and the effect of H+G group was lower than that of H+G+M group (P=0.001); and the recurrence rate of H group was significantly higher than that of H+M group (P<0.008). In patients of group H, the effect of HIFU was related to uterine size, the effect of patients with large uterine volume was significantly higher than that of small volume of uterine of patients (P=0.017, OR=2.739, 95%CI:1.200-6.251); with increasing of age, the improvement of dysmenorrhea had a increasing trend (P<0.05). Conclusions HIFU combined with GnRH-a and (or) LNG-IUS could improve the treatment effect in relief of dysmenorrhea. Based on our results, individual treatment protocol should be selected for different patients.
