Aim To explore the effects of sirolimus on the growth and development of motor,vascular,nerv-ous,and immune systems through zebrafish models.Methods After 3 hours of fertilization of zebrafish embryos,different concentrations of sirolimus were add-ed to the growth environment,and the growth and de-velopment of the embryos was recorded.Transgenic ze-brafish models labeled with blood vessels,nerves or im-mune cells were used to compare the drug effects on the growth and development of those systems.Results At the concentration of 0.5 μmol·L-1,the hatching rate and the body length(P＜0.01)were significantly smaller than those of the control group,and movement was also significantly slowed down.Meanwhile,the length of axons of the nervous system,the development of intersegmental vessels,and the growth of immune cells were significantly delayed by drug treatment.But when the concentration was below 0.1 μmol·L-1,there was no statistically difference between the control group and the sirolimus group.Conclusions When the concentration of sirolimus exceeds a certain level,it can significantly slow down the growth and development of movement,blood vessels,nervous system and im-mune system of zebrafish.Therefore,in clinical prac-tice,it is important to monitor the blood concentration of sirolimus in children on time.

OBJECTIVE: To observe the clinical efficacy of transcutaneous electrical acupoint stimulation (TEAS) at Changqiang (GV 1) based on the modulation of electro-oculogram (EOG) signal for children with mental retardation, and explore the evaluation effect of the goal attainment scale (GAS) in children with mental retardation. METHODS: Sixty children with mental retardation were randomly divided into a treatment group and a control group, with 30 cases in each one. The children in the control group were treated with conventional rehabilitation, 5 times a week. On the basis of the control group, TEAS at Changqiang (GV 1) under the modulation of EOG signal was adopted in the treatment group. When the similarity between the collected EOG signal and the template was within the range of EOG threshold, one electric stimulation was triggered at Changqiang (GV 1) for 20 s (continuous wave, 70-100 Hz in frequency, 0.1-0.2 ms in pulse width), lasting 30 min in each treatment, the intervention was given twice a week. One course of treatment was composed of 4 weeks, and 3 courses were required in total in the two groups. The infant-junior high school student's social living ability scale (S-M) and GAS were scored and compared before and after treatment in the two groups. RESULTS: After treatment, the scores of self-living ability in the treatment group and communication ability in the control group were higher than those before treatment (P<0.01, P<0.05). The scores of collective activity and motor ability in the treatment group were higher than those in the control group (P<0.05). After treatment, GAS scores were higher than before treatment in both groups (P<0.001), and the score in the treatment group was higher than the control group (P<0.05). CONCLUSION TEAS under the modulation of EOG signal is conductive to improving the collective, motor and self-living abilities of the children with mental retardation and promoting children's individual goals. Compared with the standard score of S-M, the T value of GAS can better reflect the subtle progress of individual.

ObjectiveTo establish a quantitative analysis multi-components by single marker method （QAMS） for five main components （aucubin， geniposidic acid， chlorogenic acid， asperuloside and rutin） in Eucommiae Folium， to verify its feasibility and applicability in the determination of Eucommiae Folium， so as to provide a scientific basis for the development of quality standard of this herb. MethodHigh performance liquid chromatography was performed on a Welch Boltmatetm™ C₁₈ column （4.6 mm×100 mm， 2.7 μm） with methanol （A）-0.2% phosphoric acid aqueous solution （B） as the mobile phase for gradient elution （0-8 min， 3%A； 8-10 min， 3%-11%A； 10-26 min， 11%A； 26-27 min， 11%-25%A； 27-60 min， 25%-32%A）， the column temperature was set at 30 ℃， the flow rate was 0.6 mL·min^-1， the detection wavelengths were at 210 nm and 254 nm. Chlorogenic acid was used as an internal reference to establish the relative correction factors （f） between it and the other four components， and the contents of the five components in 14 batches of Eucommiae Folium were determined by QAMS and external standard method （ESM）， respectively. ResultThe f values of chlorogenic acid to aucubin， geniposidic acid， asperuloside and rutin were 3.13， 1.45， 2.64 and 0.56， respectively. Repeatability was good under different experimental conditions， relative standard deviation （RSD） was <5.0%. The contents of aucubin， geniposidic acid， chlorogenic acid， asperuloside and rutin in 14 batches of Eucommiae Folium were 1.340-28.975， 0.252-36.086， 10.016-27.443， 1.396-8.646， 0.533-1.766 mg·g^-1， respectively. There were no significant difference between content results of QAMS and that of ESM （RSD<5.0%）. ConclusionQAMS established with chlorogenic acid as the internal reference can be used to determine the contents of five components in Eucommiae Folium， and this method is simple and accurate. After comprehensive evaluation， the quality standard of Eucommiae Folium in subsequent editions of Chinese Pharmacopoeia is suggested that three main active components， chlorogenic acid， aucubin and geniposidic acid， are selected as quality markers， and their content limits are recommended not less than 1.5%， 1.0% and 1.0%， respectively. This quality standard draft can avoid the potential quality risk due to poor specificity and low content limit of the index component （chlorogenic acid） in the previous editions of Chinese Pharmacopoeia.

BACKGROUND: The prognostic benefit of complete revascularization in elderly patients (aged over 75 years) with multi-vessel disease and acute coronary syndrome (ACS) is currently unclear. This study aimed to determine the long-term prognostic impact of complete revascularization in this population. METHODS: We conducted this study using data obtained from the BleeMACS (Bleeding complications in a Multicenter registry of patients discharged after an Acute Coronary Syndrome) registry, which was carried out from 2003 to 2014. The objective was to categorize older patients diagnosed with ACS into two groups: those who underwent complete revascularization and those who did not. Propensity score matching and the Kaplan-Meier analysis were employed to examine differences in one-year clinical outcomes. The primary endpoint was major adverse cardiovascular event (MACE), which encompassed a combination of all-cause mortality and myocardial infarction. RESULTS: Out of 1263 patients evaluated, 445 patients (35.2%) received complete revascularization. Patients who underwent complete revascularization had a higher prevalence of hypertension and prior percutaneous coronary intervention compared to those who did not. During the one-year follow-up period, complete revascularization was associated with a significantly decreased risk of MACE [13.7% vs. 20.5%, hazard ratio (HR) = 0.63, 95% CI: 0.45-0.88, P = 0.007] and a lower risk of myocardial infarction (5.9% vs. 9.9%, HR = 0.55, 95% CI: 0.33-0.92, P = 0.02). However, it was not linked to a lower risk of all-cause death (9.5% vs. 13.5%, HR = 0.68, 95% CI: 0.45-1.02, P = 0.06). Similar results were observed in the subgroup analysis. CONCLUSIONS Long-term clinical improvements were observed in ACS patients aged over 75 years with multi-vessel disease who achieved complete revascularization. Therefore, adhering to guidelines for complete revascularization should be recommended for elderly patients.

Objective: To evaluate the advantages and safety of Plerixafor in combination with granulocyte colony-stimulating factor (G-CSF) in autologous hematopoietic stem cell mobilization of lymphoma. Methods: Lymphoma patients who received autologous hematopoietic stem cell mobilization with Plerixafor in combination with G-CSF or G-CSF alone were obtained. The clinical data, the success rate of stem cell collection, hematopoietic reconstitution, and treatment-related adverse reactions between the two groups were evaluated retrospectively. Results: A total of 184 lymphoma patients were included in this analysis, including 115 cases of diffuse large B-cell lymphoma (62.5%) , 16 cases of classical Hodgkin's lymphoma (8.7%) , 11 cases of follicular non-Hodgkin's lymphoma (6.0%) , 10 cases of angioimmunoblastic T-cell lymphoma (5.4%) , 6 cases of mantle cell lymphoma (3.3%) , and 6 cases of anaplastic large cell lymphoma (3.3%) , 6 cases of NK/T-cell lymphoma (3.3%) , 4 cases of Burkitt's lymphoma (2.2%) , 8 cases of other types of B-cell lymphoma (4.3%) , and 2 cases of other types of T-cell lymphoma (1.1%) ; 31 patients had received radiotherapy (16.8%) . The patients in the two groups were recruited with Plerixafor in combination with G-CSF or G-CSF alone. The baseline clinical characteristics of the two groups were basically similar. The patients in the Plerixafor in combination with the G-CSF mobilization group were older, and the number of recurrences and third-line chemotherapy was higher. 100 patients were mobilized with G-CSF alone. The success rate of the collection was 74.0% for one day and 89.0% for two days. 84 patients in the group of Plerixafor combined with G-CSF were recruited successfully with 85.7% for one day and 97.6% for two days. The success rate of mobilization in the group of Plerixafor combined with G-CSF was substantially higher than that in the group of G-CSF alone (P=0.023) . The median number of CD34(+) cells obtained in the mobilization group of Plerixafor combined with G-CSF was 3.9×10(6)/kg. The median number of CD34(+) cells obtained in the G-CSF Mobilization group alone was 3.2×10(6)/kg. The number of CD34(+) cells collected by Plerixafor combined with G-CSF was considerably higher than that in G-CSF alone (P=0.001) . The prevalent adverse reactions in the group of Plerixafor combined with G-CSF were grade 1-2 gastrointestinal reactions (31.2%) and local skin redness (2.4%) . Conclusion: The success rate of autologous hematopoietic stem cell mobilization in lymphoma patients treated with Plerixafor combined with G-CSF is significantly high. The success rate of collection and the absolute count of CD34(+) stem cells were substantially higher than those in the group treated with G-CSF alone. Even in older patients, second-line collection, recurrence, or multiple chemotherapies, the combined mobilization method also has a high success rate of mobilization.

According to the theory of acupuncture-moxibustion for the treatment of spirit, starting from the relationship between eye movement and spirit, the application of electrooculogram (EOG) signal acquisition and analysis technology for the clinical treatment of spirit by acupuncture-moxibustion is discussed. Based on the nonlinear dynamic characteristics of EOG signals, it is proposed to apply the approximate entropy algorithm to extract the EOG signal characteristics in autism spectrum disorder children under different behavior states, which could realize the preliminary exploration of the correlation between EOG signals and cognitive activities. This could provide a possibility to objectively reflect the patient' s current mental state, and could be used as a potential method to grasp spirit in clinical acupuncture- moxibustion treatment. Furthermore, considering the characteristics of acupoint stimulation on the body surface, the EOG signal acquisition and analysis technology could further be combined with biofeedback technology, and a new idea for clinical acupuncture-moxibustion to treat spirit guided by biofeedback of EOG is proposed.

In the present study, the contents of seven active components [genipinic acid(GA), protocatechuic acid(PCA), neochlorogenic acid(NCA), chlorogenic acid(CA), cryptochlorogenic acid(CCA),(+)-pinoresinol di-O-β-D-glucopyranosid(PDG), and(+)-pinoresinol 4'-O-β-D-glucopyranoside(PG)] of Eucommiae Cortex in aortic vascular endothelial cells of spontaneously hypertensive rats(SHR) were simultaneously determined by ultra-high liquid chromatography-triple quadrupole mass spectrometry(UPLC-MS/MS). The qualified SHR models were selected. The primary aortic endothelial cells(VECs) of rats were separated and cultured by ligation and adherence, followed by subculture. After successful identification, an UPLC-MS/MS method for simultaneously determining the contents of GA, PCA, NCA, CA, CCA, PDG, PG in seven components of Eucommiae Cortex in VECs was established, including specificity, linearity, matrix effect, recovery, accuracy, precision and stability. The established method had the lo-west limit of quantification of 0.97-4.95 μg·L~(-1), accuracy of 87.26%-109.6%, extraction recovery of 89.23%-105.3%, matrix effect of 85.86%-106.2%, and stability of 86.00%-112.5%. Therefore, the established accurate UPLC-MS/MS method could rapidly and simultaneously determine the contents of the seven active components of Eucommiae Cortex in VECs of SHRs, which provided a refe-rence for the study of cellular pharmacokinetics of active components of Eucommiae Cortex extract.

The application status of acupuncture and moxibustion therapy for assisted reproductive field in the United States was analyzed, and the existing problems and future development directions were discussed. According to the survey on the 456 websites of assisted reproductive clinic in the United States mentioned in the report of U.S. Centers for Disease Control and Prevention (CDC), 111 clinics among 456 assisted reproductive clinics recommend and used acupuncture and moxibustion therapy, accounting for 24.3%. Acupuncture and moxibustion therapy had obvious effect, good safety and low cost, and the assisted reproductive institutions in the United States had a high degree of application and recognition to acupuncture and moxibustion therapy. However, some problems, such as immature treatment scheme, unclear mechanism and imperfect insurance policies, still existed. In the future, the advantages of Chinese traditional acupuncture and moxibustion should combine with international modern assisted reproductive technology, and multi-center and large-sample clinical randomized controlled trials and basic experimental research on the mechanism of acupuncture and moxibustion for assisted reproduction should be carried out.

The present study investigated the pharmacodynamic material basis of Laportea bulbifera in the treatment of rheumatoid arthritis. Firstly, human rheumatoid arthritis fibroblast-like synoviocyte line MH7A was cultured in vitro and treated with tumor necrosis factor alpha(TNF-α, 50 ng·mL~(-1)). The proliferation and the levels of inflammatory cytokines such as prostaglandin E2(PGE2), interleukin-1β(IL-1β), and interleukin-6(IL-6) of the MH7A cells exposed to the serum containing L. bulbifera were determined to evaluate the anti-rheumatoid arthritis effects of the serum. Furthermore, the ultra-performance liquid chromatography tandem mass spectrometry fingerprints of the L. bulbifera crude extract, the drug-containing serum, and the drug-free serum were compared to identify the compounds newly generated in the serum after oral administration of the extract. According to the peak areas of common peaks and the results of anti-rheumatoid arthritis effect test, the active components were identified. The serum containing L. bulbifera significantly inhibited the proliferation of the MH7A cells activated by TNF-α and the expression of PGE2, IL-6, and IL-1β. Thirty newly generated compounds were detected in the drug-containing serum. Among them, neochlorogenic acid, cryptochlorogenic acid, chlorogenic acid, rutin, isoquercitrin, luteoloside, kaempferol-3-O-rutinoside, and quercitrin were also present in the crude extract. Twelve characteristic peaks(3, 7, 8, 14, 18, 19, 21, 23, 24, m6, m7, and m15) were significantly correlated with the pharmaceutical effect. According to the correlations, neochlorogenic acid, cryptochlorogenic acid, and chlorogenic acid had great contributions to the anti-rheumatoid arthritis activity. This study preliminarily clarified the potential pharmacodynamic substances of L. bulbifera in the treatment of rheumatoid arthritis, which laid a theoretical and experimental foundation for further development and application of the medicinal plant.

Laportea bulbifera extract is effective in resisting inflammation and shows a good therapeutic effect on rheumatoid arthritis in rats. However, the absorption characteristics of active components in L. bulbifera extract in Caco-2 cells are still unclear, which limits the in-depth development of L. bulbifera resources. The purpose of this study was to investigate the absorption and transport mechanism of the active components of L. bulbifera extract in the Caco-2 cell model and explore the effects of different factors(concentration, time, pH value, temperature, and efflux transporter inhibitor) on its uptake and transport. The results showed that L. bulbifera extract at the concentration of 2.0-8.0 mg·mL~(-1) showed no toxicity to Caco-2 cells. The uptake and transport of L. bulbifera extract in the Caco-2 cell model were concentration-dependent and time-dependent. The main absorption mechanism was passive diffusion, and acidic condition(pH 5.0-6.0) and 37 ℃ were more favorable for drug absorption. P_(app)>1.0×10~(-6 )cm·s~(-1) of each component indicated that L. bulbifera was a moderately absorbed drug. P-gp, MRP2, and BCRP were not involved in its uptake and transport.
