AIM: To compare N-LOK with ?-CD on inclusion ability for the volatile oil from Duhuo Jisheng Granula (Radix Angelicae, Pubescentis, Herba Asari, Radix Saposhni-koviae, etc). and its process. METHODS: Colloidal mill and mixer were adopted, and analysis was on use of DSC and GC/MS. RESULTS: N-LOK inclusion complex included oil ratio was twice as large as the ?-CD, GC/MS analysis showed that the main components of volatile oil before and after being covered had no significant difference. CONCLUSION: N-LOK inclusion complex included oil ratio was far higher than the ?-CD. N-LOK inclusion complex could spray to dry directly, but ?-CD inclusion complex needed refrigeration and low temperature were necessary. The method of covered with N-LOK is suitable for mass production in the traditional Chinese patent medicine in the size of manufacture.

Objective.To probe into the influence of Jiannao Anshen Capsule of Miao medicine on the behavioral performance,content of cytokine interleukin-1 (IL-1),neuroendocrine hormone melatonin (MT) and monoamine neurotransmitter 5-hydroxytryptamine (5-HT) of rats with sleep deprival.Methods All of the 60 rats were evenly and randomly divided into 5 groups:the normal control group,model control group,estazolam group,Zaoren Anshen group,and Jiannao Anshen of Miao medicine group,respectively.Every group had 12 rats.Sleep deprivation rat model was established by intraperitoneal injection of para-chlorophenyla lanice (PCPA).After successful modeling,the rats were intragastrically administrated with corresponding medicines.The contents of serum 5-HT,IL-1 and MT and the contents of 5-HT,MT in brain tissue were determined.Results Behavioral score,the contents of 5-HT,MT and IL-1 in serum and the contents of 5-HT,MT in brain tissue in insomnia rats caused by PCPA were significantly decreased as compared with normal control group (P ＜ 0.05).In the Jiannao Anshen group,estazolam group and Zaoren Anshen group,the behavioral score,the content of 5-HT,MT and IL-1 in serum and the content of 5-HT and MT in brain tissue of insomnia rats were significantly increased as compared with model control group (P ＜ 0.05).The behavioral score,the content of 5-HT,MT and IL-1 in serum and the content of 5-HT and MT in brain tissue of insomnia rats were not statistically significant different among Jiannao Anshen group,estazolam group and Zaoren Anshen group (P ＞ 0.05).Conclusion Jiannao Anshen capsule of Miao medicine could obviously improve the sleep quality of rats with sleep deprival.The mechanism may be related to improving the content of IL-1,MT and 5-HT.

Objective: This work aimed to construct stable MCF-7 cell sublines from which staphylococcal nuclease domain con-taining 1 (SND1) expression was interfered to analyze the effect of SND1 silencing on the proliferation and metastasis of MCF-7 cells. Methods: The lentivirus that could mediate SND1 silencing was prepared. MCF-7 cells were infected with the lentiviruses to construct stable sub-cell lines. Quantitative real-time polymerase chain reaction and Western blot analysis were employed to determine SND1 ex-pression level. MTS, wound healing, and transwell assays were applied to analyze the effect of SND1 silencing on the proliferation, mi-gration, and invasion of MCF-7 cells. Results: A lentivirus expression vector that contains sequences encoding shRNAs targeting SND1 and an shRNA negative control were successfully established. The lentiviruses (LV-SH1, LV-SH2, LV-SH3, and 和 LV-NC) were then collected and packaged. Stabilized MCF-7 sublines were prepared through infection with lentiviruses. The most efficient MCF-7 stable cell subline, MCF-SH3, was selected for SND1 silencing. Compared with the control cell, the proliferation, migration, and inva-sion potential of MCF-SH3 were significantly decreased. Conclusion: SND1 could promote the proliferation, migration, and invasion of breast cancer cells. Thus, silencing SND1 expression will inhibit such proliferation, migration, and invasion. These results indicated that the unusual expression of SND1 is associated with breast cancer and may participate in cancer progression by affecting prolifera-tion, migration, and invasion.

OBJECTIVE:To observe clinical efficacy and safety of paclitaxel or 5-fluorouracil combined with nadaplatin in the treatment of advanced nasopharyngeal carcinoma(NPC). METHODS:42 patients with advanced NPC were randomly divided into observation group and control group(n=21). 2 groups of patients were treated with radiotherapy. Observation group received che-motherapy of paclitaxel(135 mg/m2,d1)and nedaplatin(80 mg/m2,d 2-4);control group received chemotherapy of 5-fluoroura-cil(500 mg/m2,d1-5)and nedaplatin(80 mg/m2,d1-3);a treatment course lasted for 3 weeks,and both groups received 2 courses of treatment. Clinical efficacy, survival rate and ADR were observed in 2 groups. RESULTS:The overall response rate was 95.2%in observation group and 90.5% in control group,with no significant difference between 2 groups (P>0.05). The 3-year overall survival rate and progression-free survival rate were 81.0% and 71.4% in observation group and 76.2% and 66.6% in control group,with no significant difference(P>0.05). The incidence of nausea and vomiting in observation group were lower than in con-trol group,while the incidence of oral mucosa inflammation was higher than control group,with statistical significance(P<0.05). CONCLUSIONS:The chemoradiotherapy of paclitaxel or 5-fluorouracil combined with nadaplatin have similar therapeutic efficacy for advanced NPC. ADR by chemoradiotherapy should be monitored closely and treated timely.

Objective To investigate the incidence changes, clinical characteristics and pregnant outcomes of pernicious placenta previa. Methods A retrospective cohort analysis on 316 cases with placenta previa in the Peking University First Hospital from January 2008 to December 2014. The research group were 60 cases with the patients of placenta previa with the history of cesarean section, and the control group were placenta previa without the history of cesarean section. Compared with the incidence, intraoperative blood loss, the pregnancy outcomes and so on. Results (1) The average incidence rate of placenta previa during the past 7 years was 10.96‰ (316/28 837). And the cases of pernicious placenta previa was 60 (2.08‰, 60/28 837), the incidence of pernicious placenta previa was rising from 2008 to 2014 (0.91‰-3.08‰). (2) There were 145 cases of placenta privia had been translation from other hospitals in the past 7 years. The referral rate of pregnant women with placenta previa was 45.9%(145/316), and the referral rate of pernicious placenta previa (63.3%, 38/60) was significantly higher than that of non-pernicious placenta previa group (41.8%, 107/256; χ2=9.080, P=0.003). Referral the outcomes of these patients were good, and no maternal death occurred. (3) The placenta in the research group were mainly adhered in the front wall of the uterine, and the incidence was 38.5%(15/39), higher than that in the group of non-pernicious placenta previa (12.1%, 21/174; χ2=57.636, P<0.01). The incidence rate of complicated placenta increased in research group was 53.3% (32/60), higher than that in the group of non-pernicious placenta previa, compared with the control group, there was significant difference (15.6%, 40/256; χ2=39.041, P<0.01). (4) The incidence of blood loss was more than 1 000 ml, blood transfusion rate, the rate of hysterectomy and the rate of asphyxia of newborn in the research group were respectively 41.7% (25/60), 38.3%(23/60), 8.3%(5/60), 15.0%(9/60), and the incidence of the group of non-pernicious placenta previa were respectively 4.7%(12/256), 12.9%(33/256), 1.2%(3/256), 8.6%(22/256), compared those in other two groups, there were not significant difference (P<0.05). Conclusions The incidence rate of placenta previa increased year by year, patients with placenta previa has a history of cesarean section often combined with placenta in anterior wall of the uterus, and often with poor pregnancy outcomes. Hierarchical referral system is an effective means to reduce the mortality of the pernicious placenta previa.

Objective To determine platelet count (PLT),mean platelet volume (MPV),and hemodynamic changes in patients with cir-rhotic portal hypertension (CPH)post splenectomy plus pericardial devascularization (SPPD),and to assess the surgical effect on coagula-tion function.Methods A retrospective analysis was performed on 83 CPH patients undergoing SPPD in our hospital from January 2008 to December 2012.Results Compared with preoperative levels,postoperative portal venous pressure decreased,blood flow was reduced,and portal vein diameter was significantly reduced;additionally,postoperative hepatic artery diameter was increased,and hepatic artery blood flow increased.Blood alanine aminotransferase,albumin,total protein,and fibrinogen levels,thrombin time,and MPV did not significantly change 30 days postoperatively versus 7 days preoperatively(P>0.05 );the corresponding total bilirubin,activated partial thromboplastin time and prothrombin time relatively declined(P<0.05),whereas PLT and prothrombin time activity increased(P<0.05).There was a significant increase in PLT (P<0.05)but no significant change in MPV 30 days postoperatively versus 7 days preoperatively (P>0.05). Conclusion SPPD can significantly improve liver functional reserve and coagulation function in patients with CPH.
