Panax notoginseng is the dried root and rhizome of Panax notoginseng(Burk.)F.H.Chen,a perennial erect herb of the genus Ginseng of the family Wujiaceae.As a traditional Chinese medicine in our country,Panax notoginseng has a good tonic effect,and the Dictionary of Traditional Chinese Medicines has the words that Panax notoginseng is used to tonify the blood,remove the blood stasis and damage,and stop epistaxis.It can also be used to pass the blood and tonify the blood with the best efficacy,and it is the most precious one of the prescription med-icines.Eaten raw,it removes blood stasis and generates new blood,subdues swelling and stabilizes pain,stops bleeding with-out leaving stasis,and promotes blood circulation without hurting the new blood;taken cooked,it can be used to replenish and strengthen the body.Notoginsenoside R1 is a characteristic com-pound in the total saponin of Panax ginseng.In recent years,China's aging has been increasing,and the incidence of neuro-logical disorders has been increasing year by year.Meanwhile,reports on notoginsenoside R1 in the treatment of neurological disorders are increasing,and its neuroprotective effects have been exerted with precise efficacy.The purpose of this paper is to review the treatment of neurological diseases and the mecha-nism of action of notoginsenoside R1,so as to provide a certain theoretical basis for clinical use and new drug development.

BACKGROUND: There were few studies on real-world data about autologous hematopoietic stem cell transplantation (auto-HSCT) or allogeneic HSCT (allo-HSCT) in peripheral T-cell lymphoma (PTCL). This study aimed to investigate the clinical outcomes of patients who received auto-HSCT or allo-HSCT in China. METHODS: From July 2007 to June 2017, a total of 128 patients who received auto-HSCT (n  = 72) or allo-HSCT (n  = 56) at eight medical centers across China were included in this study. We retrospectively collected their demographic and clinical data and compared the clinical outcomes between groups. RESULTS: Patients receiving allo-HSCT were more likely to be diagnosed with stage III or IV disease (95% vs. 82%, P = 0.027), bone marrow involvement (42% vs. 15%, P = 0.001), chemotherapy-resistant disease (41% vs. 8%, P = 0.001), and progression disease (32% vs. 4%, P < 0.001) at transplantation than those receiving auto-HSCT. With a median follow-up of 30 (2-143) months, 3-year overall survival (OS) and progression-free survival (PFS) in the auto-HSCT group were 70%(48/63) and 59%(42/63), respectively. Three-year OS and PFS for allo-HSCT recipients were 46%(27/54) and 44%(29/54), respectively. There was no difference in relapse rate (34%[17/63] in auto-HSCT vs. 29%[15/54] in allo-HSCT, P = 0.840). Three-year non-relapse mortality rate in auto-HSCT recipients was 6%(4/63) compared with 27%(14/54) for allo-HSCT recipients (P = 0.004). Subanalyses showed that patients with lower prognostic index scores for PTCL (PIT) who received auto-HSCT in an upfront setting had a better outcome than patients with higher PIT scores (3-year OS: 85% vs. 40%, P = 0.003). Patients with complete remission (CR) undergoing auto-HSCT had better survival (3-year OS: 88% vs. 48% in allo-HSCT, P = 0.008). For patients beyond CR, the outcome of patients who received allo-HSCT was similar to that in the atuo-HSCT group (3-year OS: 51% vs. 46%, P = 0.300). CONCLUSIONS Our study provided real-world data about auto-HSCT and allo-HSCT in China. Auto-HSCT seemed to be associated with better survival for patients in good condition (lower PIT score and/or better disease control). For patients possessing unfavorable characteristics, the survival of patients receiving allo-HSCT group was similar to that in the auto-HSCT group.

BACKGROUND: Stent failure is more likely in the lipid rich and thrombus laden culprit lesions underlying ST-segment elevation myocardial infarction (STEMI). This study assessed the effectiveness of post-dilatation in primary percutaneous coronary intervention (pPCI) for acute STEMI. METHODS: The multi-center POST-STEMI trial enrolled 41 consecutive STEMI patients with symptom onset <12 hours undergoing manual thrombus aspiration and Promus Element stent implantation. Patients were randomly assigned to control group (n=20) or post-dilatation group (n=21) in which a non-compliant balloon was inflated to >16 atm pressure. Strut apposition and coverage were evaluated by optical coherence tomography (OCT) after intracoronary verapamil administration via thrombus aspiration catheter, post pPCI and at 7-month follow-up. The primary endpoint was rate of incomplete strut apposition (ISA) at 7 months after pPCI. RESULTS: There were similar baseline characteristics except for stent length (21.9 [SD 6.5] mm vs. 26.0 [SD 5.8] mm, respectively, P=0.03). In post-dilatation vs. control group, ISA rate was lower (2.5% vs. 4.5%, P=0.04) immediately after pPCI without affecting final TIMI flow 3 rate (95.2% vs. 95.0%, P>0.05) or corrected TIMI frame counts (22.6±9.4 vs. 22.0±9.7, P>0.05); and at 7-month follow-up (0.7% vs. 1.8%, P<0.0001), the primary study endpoint, with similar strut coverage (98.5% vs. 98.4%, P=0.63) and 1-year rate of major adverse cardiovascular events (MACE). CONCLUSION In STEMI patients, post-dilatation after stent implantation and thrombus aspiration improved strut apposition up to 7 months without affecting coronary blood flow or 1-year MACE rate. Larger and longer term studies are warranted to further assess safety (ClinicalTrials.gov identifi er: NCT02121223).

Objective: Moxifloxacin (MFX) shows good activity against and can be a possible antibiotic therapy to treat infection; however, other studies have shown a lower or no activity. We aimed to evaluate MFX activity against using zebrafish (ZF) model . Methods: A formulation of labeled with CM-Dil was micro-injected into ZF. Survival curves were determined by recording dead ZF every day. ZF were lysed, and colony-forming units (CFUs) were enumerated. Bacteria dissemination and fluorescence intensity in ZF were analyzed. Inhibition rates of MFX and azithromycin (AZM, positive control) were determined and compared. Results: Significantly increased survival rate was observed with different AZM concentrations. However, increasing MFX concentration did not result in a significant decrease in ZF survival curve. No significant differences in bacterial burdens by CFU loads were observed between AZM and MFX groups at various concentrations. Bacterial fluorescence intensity in ZF was significantly correlated with AZM concentration. However, with increasing MFX concentration, fluorescence intensity decreased slightly when observed under fluorescence microscope. Transferring rates at various concentrations were comparable between the MFX and AZM groups, with no significant difference. Conclusion MFX showed limited efficacy against using ZF model. Its activity needs to be confirmed.

Objective: To explore the efficacy and prognostic factors of hematopoietic stem cell transplantation (HSCT) for the treatment of patients with anaplastic large cell lymphoma (ALCL) . Methods: The clinical records of 33 ALCL patients after HSCT were collected and analyzed retrospectively to evaluate the rates of overall survival (OS) and recurrence after autologous (auto-HSCT) and allogeneic HSCT (allo-HSCT) and the factors influencing prognosis. Results: The median-age of this cohort of 33 ALCL cases at diagnosis was 31 (12-57) years old with a male/female ratio of 23/10, 24 cases (72.7%) were ALK(+) and 9 ones (27.3%) ALK(-). Of them, 25 patients (19 ALK(+) and 6 ALK(-)) underwent auto-HSCT and 8 cases (5 ALK(+) and 3ALK(-)) allo-HSCT with a median follow-up of 18.7 (4.0-150.0) months. Disease states before HSCT were as follows: only 6 patients achieved CR status and received auto-HSCT, 16 patients achieved PR (14 cases by auto-HSCT and 2 ones allo-HSCT) , the rest 11 cases were refractory/relapse (5 cases by auto-HSCT and 6 ones allo-HSCT) . There were 7 cases died of disease progression (5 after auto-HSCT and 2 allo-HSCT) and 5 cases treatment-related mortality (TRM) (2 after auto-HSCT and 3 allo-HSCT) , TRM of two groups were 8.0% and 37.5%, respectively. Both the median progression-free survival (PFS) and OS were 15 months after auto-HSCT, the median PFS and OS after allo-HSCT were 3.7 (1.0-90.0) and 4.6 (1.0-90.0) months, respectively. There was no statistically significant difference in terms of survival curves between the two groups (OS and PFS, P=0.247 and P=0.317) . The 2-year OS rates in auto-HSCT and allo-HSCT groups were 72% and 50%, respectively. The 5-year OS rates in auto-HSCT and allo-HSCT groups were 36% and 25%, respectively. Conclusion: ALCL treated by chemotherapy produced high rates of overall and complete responses. Chemotherapy followed by auto-HSCT remained to be good choice for patients with poor prognostic factors. High-risk patients should be considered more beneficial from allo-HSCT.

Objective: To evaluate clinical outcomes of autologous (auto-HSCT) and allogeneic hematopoietic stem cell transplantation (allo-HSCT) for angioimmunoblastic T-cell lymphoma (AITL) . Methods: From June 2007 to June 2017, clinical data of AITL patients who underwent HSCT in eight hospitals were assessed retrospectively. Results: Of 19 patients, 13 male and 6 female with a median age of 50 (32-60) years old, 12 auto-HSCT and 7 allo-HSCT recipients were enrolled in this study, all donors were HLA-identical siblings. Two of allo-HSCT recipients were relapsed auto-HSCT ones. There were 5 patients (5/12) in complete response (CR) status and 7 (7/12) in partial remission (PR) status before transplantation in auto-HSCT group, and 2 (2/7) in PR status and 3 (3/7) in progression disease (PD) status before transplantation in allo-HSCT group. The median follow-up for the surviving patients was 46.5 months (range, 1-100 months) for the whole series, two patients lost in auto-HSCT group. Three patients developed acute graft-versus-host disease (aGVHD) and 5 chronic graft-versus-host disease (cGVHD) after allo-HSCT. Three patients died of primary disease and 1bleeding in auto-HSCT group. One patient died of primary disease and 2 transplantation-related mortality in allo-HSCT group. The 3-year cumulative overall survival (OS) were 56% (95%CI 32%-100%) and 57% (95%CI 30%-100%) for auto-HSCT and allo-HSCT, respectively (P=0.979) . The 3-year cumulative progression-free survival (PFS) were 34% (95%CI 14%-85%) and 57% (95%CI 30%-100%) for auto-HSCT and allo-HSCT, respectively (P=0.451) . Conclusion: Both auto-HSCT and allo-HSCT were optimal choices for AITL. In clinical practice, which HSCT was better for AITL patients should be based on comprehensive factors including sensitivity to chemotherapy, risk stratification and disease status at transplantation.

This study was carried out to investigate the effect of oral administration of Dendrobium huoshanense on the expressions and activities of hepatic microsomal cytochrome P450s in mice, and to provide a reference for the evaluation of drug-drug interactions between D. huoshanense and clinical drugs. The C57BL/6 mice were randomly divided into blank control group, D. huoshanense low dose group (crude drug 1.25 g·kg⁻¹), D. huoshanense high dose group (crude drug 7.5 g·kg⁻¹), and phenobarbital positive control group (0.08 g·kg⁻¹). Each group was intragastrically administered with drugs for 2 weeks. The mice were sacrificed and their liver microsomes were prepared. The expressions of major subtypes of P450 enzyme were determined by Western blot and the probe drugs were used to detect the enzyme activities of P450 subtypes with protein expression changes. Western blot analysis showed that the protein expressions of CYP1A1, CYP1A2 and CYP2B in liver tissues were up-regulated in D. huoshanense-treated group. In vitro enzyme activity tests showed that there were no significant difference in metabolism of 7-ethoxyresorufin (a probe drug for CYP1A1) and bupropion (a probe drug for CYP2B) between D. huoshanense group and control group. The metabolism of phenacetin (a probe drug for CYP1A2) showed a statistical difference in rate Vmax, and it was significantly increased by approximately 20% in D. huoshanense group as compared with the blank control group, and the clearance CLint in treated group was also increased by about 32%. Therefore, oral administration of D. huoshanense had no effects on the activities of most hepatic P450 enzymes in mice, with no drug-drug interaction related to the P450 enzyme system in most clinical drugs theoretically. However, oral administration of D. huoshanense may accelerate the metabolism of CYP1A2-catalyzed drugs, which needs to be considered in clinical practice.

OBJECTIVETo establish DNA microarrays-based microRNA (miRNA) expression profiles of squamous cell carcinoma of larynx, using archived formalin-fixed paraffin-embedded tissue blocks, and to screen out and identify the differentially expressed miRNAs associated with the biological characteristics of this malignant disease.

METHODSTotal RNA was prepared from the formalin-fixed paraffin-embedded tissue blocks. After quality identification and fluorescent labeling, the RNA samples were hybridized with the Agilent human miRNA microarrays which contains 723 probes for human miRNAs. The data was processed with the softwares GeneSpring GX and R-Project.

RESULTSFrom the formalin-fixed paraffin-embedded tumor blocks collected, 24 RNA samples were obtained with the quality accorded to the requirement of miRNA microarray analysis, and both the hybridization and consequent data processing were accomplished. A total of 319 miRNAs were identified and among them 96 were detected in all the 24 formalin-fixed paraffin-embedded blocks of laryngeal carcinoma; and 5 differentially expressed miRNAs (false discovery rate < 0.05) were found to be associated significantly with the lymphatic metastasis of laryngeal squamous cell carcinoma (P < 0.05), including miR-23a(*), miR-28-5p, miR-15a, miR-16 and miR-425.

CONCLUSIONSHistopathological archives of well-annotated formalin-fixed paraffin-embedded tissue specimens are the valuable resources for miRNA study including to collect RNA samples for miRNA microarray analysis. A panel of differentially expressed miRNAs (miR-23a(*), miR-28-5p, miR-15a, miR-16 and miR-425) derived from the miRNA expression profile may serve as the potential molecular biomarkers for the prediction of metastasis development in laryngeal squamous cell carcinoma.

OBJECTIVETo compare the hemodynamic responses to orotracheal intubation using a Shikani Optical Stylet (SOS) laryngoscope or a Macintosh direct laryngoscope (MDLS).

METHODSTotally 41 patients with American Society of Anesthesiologists ASA physical status -aged 20-60 years and scheduled for elective surgery under general anesthesia requiring orotracheal intubation, were randomly allocated to either the SOS group (n=21) or MDLS group (n=20). After an intravenous anesthetic induction the orotracheal intubation was performed using a SOS laryngoscope or a MDLS. Blood pressure and heart rate (HR) were recorded before and after anesthetic induction immediately after intubation, and 5 minutes after intubation. Rate pressure product RPP were calculated.

RESULTSBlood pressures and RPP in both two groups significantly decreased after anesthetic induction (P<0.05) while blood pressures HR, and RPP significantly increased after orotracheal intubation (P<0.05). HR in both groups after intubation were significantly higher than the pre-induction level (P<0.05)and such an increase lasted for 3 min. HR immediately after intubation was also significantly higher in MDLS group than in SOS group (P<0.05); however, such difference was not observed in other time points (P>0.05). In the MDLS group when compared with the occurrence time required for the maximum values of systolic blood pressure (SBP)the occurrence time required for the maximum values of HR after the start of intubation and success of intubation during the observation were significantly delayed (P<0.05). Compared with the MDLS group, the occurrence time required for the maximum values of SBP after the start of intubation and the success of intubation were significantly delayed in the SOS group (P<0.05). The incidences of SBP more than 130% of baseline value and RPP more than 22 000 were not significantly differently(P>0.05). Also, the intubation time was not significantly different (P>0.05).

CONCLUSIONThe hemodynamic responses to orotracheal intubation is milder in SOS laryngoscope than in MDLS.
