Cionbufagin has anti-inflammatory and analgesic effects. It is of great value in the treatment of bone cancer pain, but its mechanism is still unclear. To generate a bone metastasis model of breast cancer, 4×10⁵ Walker-256 cells were inoculated into the left hind limb of SD rats. The experimental protocol was approved by the Medical Laboratory Animal Ethics Committee of Medical College of China Three Gorges University. Rats were randomly divided into sham, model, cionbufagin, morphine, saline, minocycline, microglia inhibitor (RS102895) and co-treatment with cionbufagin and minocycline group. The cionbufagin (5 mL·kg^-1, i.p.), morphine (8 mg·kg^-1, i.p.) and co-treatment groups (included cionbufagin 5 mL·kg^-1, i.p.) received continuous administration from day 9 to day 21. The saline, minocycline (2.5 μg·μL^-1, 20 μL), RS102895 (1.5 μg·μL^-1, 20 μL) and co-treatment groups (included minocycline 2.5 μg·μL^-1, 20 μL) received continuous administration by intrathecal cannulation from day 12 to day 21. Bone destruction of the left hind limb of rats was detected by hematoxylin-eosin staining (H&E). The pain threshold before treatment and at day 2, 5, 7, 9, 12, 14, 17 and 20 was measured by behavioral indexes. Activation and expression of a microglia marker (Iba-1) was determined by immunofluorescence and Western blot. The level of tumor necrosis factor-α (TNF-α), interleukin-1 (IL-1), and interleukin-6 (IL-6) in rat spinal cord was measured by enzyme-linked immunosorbent assay (ELISA). H&E results showed that cionbufagin effectively inhibited the destruction of bone marrow in rats with bone cancer pain; cionbufagin treatment significantly increased the mechanical and thermal pain threshold. Immunofluorescence showed that cionbufagin effectively inhibited the activation of microglia in the spinal dorsal horn. Western blot analysis confirmed that the activation of microglia in the spinal dorsal horn was inhibited by cionbufagin treatment. It was also found that the CCL2/CCR2 pathway may be involved in the analgesic effect of cionbufagin. These results suggest that cionbufagin can effectively alleviate bone cancer pain, possibly by inhibiting the release of inflammatory factors and the activation of spinal microglia cells through the CCL2/CCR2 pathway.

OBJECTIVE: To evaluate the efficacy and safety of Chinese medicine (CM) improving pregnancy outcomes after surgery for endometriosis-associated infertility. METHODS: A multicenter, randomized, double-blind placebo parallel controlled clinical trial was designed. A total of 202 patients who had laparoscopy for endometriosis-associated infertility with qi stagnation and blood stasis syndrome were included and randomly divided into the CM treatment group and placebo control group at a ratio of 1:1 using a central block randomization from May 2014 to September 2017, 101 patients in each group. The two groups received continuous intervention at 1-5 days after surgery, for 6 menstrual cycles. Before ovulation, the CM group was treated Huoxue Xiaoyi Granule (); after ovulation, Bushen Zhuyun Granule ( was involved. The control group was treated with placebo. Transvaginal ultrasonography was performed every menstrual cycle during the treatment, and female hormone levels in the follicular and luteal phases were measured during the 1st, 3rd and 6th menstrual cycles. The analysis was continued until pregnancy. The primary outcomes were clinical pregnancy rate and pregnancy outcome, and the secondary outcomes were follicular development and endometrial receptivity. Safety evaluations were performed before and after treatment. RESULTS: (1) Clinical pregnancy and live birth rates: the clinical pregnancy and live birth rates of the CM group were significantly higher than those of the placebo group [44.6% (45/101) vs. 29.7% (30/101), 34.7% (35/101) vs. 20.8% (21/101), both P<0.05]. (2) Follicle development: the incidence of dominant follicles, rate of cumulative cycle ovulation, and rate of cumulative cycle mature follicle ovulation were significantly higher in the CM group than those in the placebo group [93.8% (350/373) vs. 89.5% (341/381), 80.4% (275/342) vs. 69.1% (253/366), 65.8% (181/275) vs 56.1% (142/253), P<0.05 or P<0.01]). The incidence of cumulative cycle luteinized unruptured follicle syndrome was significantly lower in the CM group than in the placebo group [11.7% (40/342) vs. 17.8% (65/366), P<0.05). (3) Endometrial receptivity: after treatment, both endometrial types and endometrial blood flow types in the CM group were mainly types A and B, while those in the placebo group were mainly types B and C, with a significant difference between the two groups (both P<0.05). (4) Adverse events: the incidence of adverse events between the two groups was not significantly different (P>0.05). CONCLUSION Strategies for activating blood circulation-regulating Gan (Liver)-tonifying Shen (Kidney) sequential therapy can effectively improve the clinical pregnancy rate and live birth rate of endometriosis-associated infertility with qi stagnation and blood stasis after laparoscopy, improve follicular development, promote ovulation, improve endometrial receptivity, while being a safe treatment option.

Objectives: The aims of this study were to assess the associations between parity and metabolic syndrome (MetS) and its components and to evaluate the effects of body mass index (BMI) on these associations. Methods: A total of 5,674 women were enrolled from Jidong and Kailuan communities (Tangshan, Hebei) in Northern China. All participants completed standardized questionnaires, physical examination, and biochemical measurements. Logistic regression analysis was used to test the associations. Results: Compared with women with parity of one, nulliparous women had decreased odds ratios ( s ); those with parity of two had odds of abdominal obesity [ = 1.45, 95% confidence interval ( ) 1.17-1.81, < 0.001], high blood pressure ( = 1.26, 95% 1.03-1.54, = 0.025), elevated fasting glucose levels ( = 1.36, 95% 1.03-1.79, = 0.029), and MetS ( = 1.39, 95% 1.13-1.73, = 0.002); and those with parity of three or more had increased odds of elevated triglyceride levels ( = 1.42, 95% 1.04-1.94, = 0.027) and MetS ( = 1.50, 95% 1.10-2.05, = 0.011) after complete adjustment for confounders. Furthermore, BMI and age subgroups partially modified the associations between parity and MetS and its components. Conclusions Parity is positively associated with MetS and select components in women. BMI is an important modifier involved in the associations between parity and MetS.

OBJECTIVE: To investigate the clinical manifestations and laboratory features of B-ALL patients with EP300-ZNF384 fusion gene positive, so as to improve the understanding of this subtype disease. METHODS: The clinical data of 3 B-ALL patients with EP300-ZNF384 fusion gene positive admitted in Department of Hematology, the first medical center of Chinese PLA general hospital from February 2017 to February 2018 were collected and analyzed retrospectively. The clinical and laboratory characteristics as well as the therapentic outcome in B-ALL patients with EP300-ZNF384 fusion gene positive were analyzed. RESULTS: The fusion gene of EP300-ZNF384 was detected in 8.1%(3/37) of B-ALL patients. All cases showed the normal karyotype and aberrant CD13 and/or CD33 expression for immunophenotype. 3 patients were sensitive to traditional chemotherapy. CONCLUSION The B-ALL with EEP300-ZNF384 fusion gene positive may be a subgroup of B-ALL with a uniqe clinical characteristis and laboatorial features. EP300-ZNF384 positive patients show a good response to conventional chemotherapy, suggesting a favorable prognosis.

OBJECTIVE: To investigate the clinical efficacy, related side-effectt and long-term survival condition of Philadelphia chromosome positive acute lymphoblastic leukemia (Ph ALL) patients treated with second generation TKI dasatinib and chemotherapy followed by allogeneic hematopoietic stem cell transplantation (allo-HSCT). METHODS: Clinical data of 19 newly diagnosed as Ph ALL patients treated by dasatinib, chemotherapy and allo-HSCT from January 2012 to September 2018 were collectd and analyzed. RESULTS: There were 10 males and 9 females with median age of 29 years old. 14 patients were BCR/ABL P190 positive while 5 with BCR/ABL P210 positive. Three patients had complex karyotype, and 3 cases were confirmed to have central nervous system leukemia. All the patients received treatment with the induction chemotherapy regimen of VDCLP and consolidation regimens such as HD-MTX and MAE. 11 patients (57.9%) received dasatinib during induction chemotherapy, 3 patients (15.8%) received dasatinib after remission and 5 patients (26.3%) received dasatinib to replace imatinib. Side-effect appeared in 3 patients including rash, edema and nausea. All the patients got morphological remission and 7 patients(63.6%) got MMR after 4 weeks of induction chemotheraphy. 17 patients (89.5%) got MMR and 15 patients(78.9%) got CMR before allo-HSCT. All the patients received related bone marrow and peripheral hematopoietic stem cell transplantation from related donors, the median time of WBC and platelet engraftment were 12 d and 14 d after transplantation, respectively. The incidence rate of aGVHD and cGVHD were 42.1% and 57.9% respectivety. 13 patients received therapy of dasatinib after HSCT but 7 patients discontinued because of severe headache, vomiting and serious effusions. All the patients were followed-up for the median time of 42 months, the 3-year and 5-year OS both were 94.4%, and 3-year and 5-year RFS of 81.9% and 71.6%, respectively. CONCLUSION First-line administration of dasatinib and chemotherapy followed by allo-HSCT for treatment of PhALL is effective and patients can well-tolerate, the patients long-tern survival maybe superior to that of the patients treated with first generation TKI.

OBJECTIVE: To investigate the risk factors for cow's milk protein allergy (CMPA) among infants through a multicenter clinical study. METHODS: A total of 1 829 infants, aged 1-12 months, who attended the outpatient service of the pediatric department in six hospitals in Shenzhen, China from June 2016 to May 2017 were enrolled as subjects. A questionnaire survey was performed to screen out suspected cases of CMPA. Food avoidance and oral food challenge tests were used to make a confirmed diagnosis of CMPA CMPA. A multivariate logistic regression analysis was used to investigate the risk factors for CMPA. RESULTS: Among the 1 829 infants, 82 (4.48%) were diagnosed with CMPA. The multivariate logistic regression analysis showed that maternal food allergy (OR=4.91, 95%CI: 2.24-10.76, P<0.05), antibiotic exposure during pregnancy (OR=3.18, 95%CI: 1.32-7.65, P<0.05), and the introduction of complementary food at an age of <4 months (OR=3.55, 95%CI: 1.52-8.27, P<0.05) were risk factors for CMPA, while exclusive breastfeeding (OR=0.21, 95%CI: 0.08-0.58, P<0.05) and the introduction of complementary food at an age of >6 months (OR=0.38, 95%CI: 0.17-0.86, P<0.05) were protective factors. CONCLUSIONS The introduction of complementary food at an age of <4 months, maternal food allergy, and antibiotic exposure during pregnancy are risk factors for CMPA in infants.

OBJECTIVE: To study the association of related maternal factors with the susceptibility to congenital hypothyroidism (CH) in neonates. METHODS: A case-control study was designed. The neonates who were diagnosed with CH in Neonatal Screening Center of Henan Province from January 1, 2016 to December 31, 2017 were enrolled as cases. Healthy neonates, matched for sex and age were enrolled as controls. A conditional logistic regression analysis and additive and multiplicative interaction analyses were used to identify the risk factors for susceptibility to CH. RESULTS: A total of 2 771 661 neonates were screened during this period, among whom 1 494 neonates were diagnosed with CH, with a crude incidence rate of 53.9/100 000. A total of 843 pairs of the cases and the controls completed the telephone survey and provided qualified data. The conditional logistic regression analysis showed that an older maternal age at delivery, a low educational level in mothers, living in the rural area, a family history of thyroid diseases, histories of exposure to formaldehyde during pregnancy, exposure to radiation during pregnancy, and medication during pregnancy, were risk factors for CH (P<0.05), while low maternal age at delivery and progesterone intake during pregnancy were protective factors against CH (P<0.05). CONCLUSIONS An older maternal age at delivery, a low educational level in mothers, living in the rural area, a family history of thyroid diseases, and histories of exposure to formaldehyde during pregnancy, exposure to radiation during pregnancy and medication during pregnancy may increase the susceptibility to CH in neonates.

OBJECTIVE: To explore the effect of early intervention electroacupuncture (EA) at "Baihui" (GV 20), "Dazhui" (GV 14) and "Shenshu" (BL 23) on the learning-memory ability and the expression of phosphorylated Tau protein in the hippocampus of SAMP8 mice, so as to provide reference for the intervening period of EA for Alzheimer's disease (AD). METHODS: A total of 36 3-month old SAMP8 mice were randomly divided into a model group, a 3-month-old EA group and a 9-month-old EA group, 12 mice in each group. Twelve normal SAMR1 mice with the same age were taken as the control group. The mice in the 3-month-old EA group and 9-month-old EA group were treated with EA at "Baihui" (GV 20), "Dazhui" (GV 14) and "Shenshu" (BL 23) separately 3 months old and 9 months old (continuous wave, 2 Hz, 1.5-2 mA), 20 min each time, once a day, 8 days as a course of treatment, with an interval of 2 days between courses, totally 3 courses of treatment were given. The mice sample in each group was collected at the age of 10 months after the learning-memory ability tested by Morris water maze. The expression of phosphorylated Tau protein in the hippocampus was detected by immunohistochemistry and Western blot, and the expression of Tau mRNA was detected by real-time PCR. RESULTS: Compared with the control group, in the model group, the escape latency was significantly increased (<0.01), the time of stay in the original platform quadrant and the number of crossing the platform quadrant were reduced (<0.01), and the expressions of phosphorylated Tau protein and Tau mRNA in hippocampus were increased (<0.01). Compared with the model group, in the 3-month-old EA group and 9-month-old EA group, the escape latency was significantly reduced (<0.05), the time of stay in the original platform quadrant and the number of crossing the platform quadrant were increased (<0.05), and the expressions of phosphorylated Tau protein and Tau mRNA in hippocampus were reduced (<0.05). Compared with the 9-month-old EA group, in the 3-month-old EA group, the escape latency was significantly reduced (<0.05), the time of stay in the original platform quadrant and the number of crossing the platform quadrant were increased (<0.05), and the expressions of phosphorylated Tau protein and Tau mRNA were reduced (<0.01). CONCLUSION The early EA intervention could more effectively improve the learning-memory ability and inhibit phosphorylation of Tau protein in the hippocampus of SAMP8 mice.

OBJECTIVE: To explore the mechanism of catgut embedding at back- points on nonalcoholic steatohepatitis (NASH) in rats based on IKK/IKB/NF-κB signaling pathway and downstream inflammatory factors. METHODS: Eighty SPF SD rats were selected, among them 10 rats were selected divided into a normal group (group A), and the remaining 70 rats were fed with high-fat diet to establish NASH model. At the end of 12 weeks, 10 rats were randomly selected to verify whether the model establishment was successful. Then the remaining 60 rats were randomly divided into a model group (group B), a catgut embedding at back- points group (group C), a catgut embedding at abdominal points group (group D), an acupuncture at back- points group (group E), a sham catgut embedding group (group F) and a western medication group (group G), 10 rats in each group. The rats in the group C were treated with catgut embedding at "Ganshu" (BL 18), "Pishu" (BL 20), "Weishu" (BL 21) and "Shenshu" (BL 23); the rats in the group D were treated with catgut embedding at "Daheng" (SP 15), "Fujie" (SP 14), "Huaroumen" (ST 24) and "Tianshu" (ST 25); the rats in the group E were treated with acupuncture at the same acupoints as the group C; the rats in the group F were treated with catgut embedding at back- points but the needle did not enter subcutaneous tissue gamma; the rats in the group G were treated with intragastric administration of vitamin E capsule. All the treatment was given for 4 weeks. The rats in the group A were fed with normal diet until the end of 16 weeks without any intervention. The rats in the group B continued to be fed with high-fat diet until the end of 16 weeks. After the intervention, the liver index was calculated; the liver histomorphology was observed by HE staining; the liver function [alanine aminotransferase (ALT), gamma glutamyl transferase (γ-GGT), alkaline phosphatase (ALP)] and blood lipid [serum total cholesterol (TC), triglyceride (TG), low density lipoprotein (LDL)] were measured by serum biochemistry. The serum levels of TNF-α, IL-6 and IL-1βwere detected by ELISA, and the expressions of IKK-α, NF-κBp65, IL-6, IL-1β and TNF-α proteins in liver tissue were detected by Western blot. The temperature of the conception vessel and the governor vessel was measured by infrared thermography. RESULTS: Compared with the group A, the obvious steatosis and inflammatory cell infiltration were observed in the group B, and the body weight, liver wet-weight and liver index were all increased (<0.01). Compared with the group B, the liver tissue morphology in the group C, the group D, the group E and the group G was improved in varying degrees, and the liver index was decreased (<0.05), which was the most significant in the group C (<0.05). Compared with the group A, the ALT, γ-GGT, ALP, TG, TC, LDL, TNF-α, IL-6 and IL-1β were all increased in the group B (<0.01); compared with the group B, the ALT, γ-GGT, ALP, TG, TC, LDL, TNF-α, IL-6 and IL-1β in all intervention groups were all decreased in varying degrees (<0.01, <0.05), which was the most significant in the group C (<0.01). Compare with the group A, the expressions of IKK-α, NF-κBp65, TNF-α, IL-6 and IL-1βproteins in the group B were all increased (<0.01); compared with the group B, the expressions of IKK-α, NF-κBp65, TNF-α, IL-6 and IL-1βproteins in all intervention groups were decreased in varying degrees (<0.05), which was the most significant in the group C (<0.01). Compared with the group A, the temperature of the conception vessel and governor vessel was decreased in the group B (<0.01). Compared with the group B, the temperature of the conception vessel and governor vessel was all increased in the group C, the group D and the group E (<0.01); the temperature of the conception vessel in the group C was similar to that in the group D (>0.05), while the temperature of the governor vessel in the group C was superior to that in the group D (<0.05). CONCLUSION The catgut embedding at back- points might inhibit the activation of IKK/IKB/NF-κB signaling pathway to interrupt the inflammatory cascade, and reduce the "second hit" of inflammatory factors on liver, which could slow down NASH progress and prevent and treat NASH.

200 µm, a circumference > 60 degrees, and a cap thickness < 450 µm. The percentage distributions of CT pixel attenuation ≤ 20, 30, 40, and 50 HU were calculated using quantitative histogram analysis.RESULTS: A total of 271 transverse sections were co-registered between CCTA and pathological analysis. Overall, 26 lipid cores and 16 fibrous plaques were identified by pathological analysis. There was no significant difference in median CT attenuation between the lipid and fibrous plaques (51 HU [interquartile range, 46–63] vs. 57 HU [interquartile range, 50–64], p = 0.659). The median percentage of CT pixel attenuation ≤ 30 HU accounted for 11% (5–17) of lipid-core plaques and 0% (0–2) of fibrous plaques (p < 0.001). The sensitivity and specificity of the method for diagnosing lipid plaques by the average CT pixel attenuation ≤ 30 HU were 80.8% and 87.5%, respectively. The area under the receiver operator characteristics curve was 0.898 (95% confidence interval: 0.765–0.970; 3.0% was the best cut-off value). The diagnostic performance was significantly higher than those of the average pixel CT attenuation percentages ≤ 20, 40, and 50 HU and the mean CT attenuation (p < 0.05).CONCLUSION: In in vivo conditions, with the pathological lipid core as the gold standard, quantification of the percentage of average CT pixel attenuation ≤ 30 HU in the histogram can be useful for accurate identification of lipid plaques.]]>
