OBJECTIVETo evaluate the short- and long-term prevalence of persistent uncovered struts and in-stent thrombus after sirolimus-eluting stent (SES) implantation by optical coherence tomography (OCT).

METHODSOCT was performed for 31 SES in 21 patients at 3 months and for 30 SES in 21 patients at 2 years post SES implantation. Thickness of new intima inside each strut was measured and thickness equal to 0 microm was defined as an uncovered strut. Existence of in-stent thrombus was also evaluated.

RESULTSA total of 4545 struts and 3707 struts were evaluated at 3 months and at 2 years post SES implantation, respectively. New intima at 2 years was significantly thicker than that at 3 months [(71 +/- 93) microm vs. (29 +/- 41) microm, P < 0.01]. Percent of uncovered struts at 2 years was significantly lower than that at 3 months (5% vs. 15%, P < 0.01). Prevalence of uncovered struts was similar at 2 years and at 3 months (81% vs.95%, P > 0.05). Subclinical thrombus was recognized in 14% patients at 3 months and 2 years post SES implantation.

CONCLUSIONSNeointimal coverage inside the SES is a continuous process and the number of uncovered struts decreased from 3 months to 2 years after SES implantation. Few uncovered struts could still be visualized in the majority of patients at 2 years post SES implantation.

Objective To explore the application of event-related potentials (ERP) by positive, negative, and neutral face expression images in the evaluation of mood disorders in brain traumatic patients.Methods ERP was tested by face expression images in 24 patients mainly with anxiety and depression symptoms (depression group) and 19 patients mainly with hostile and suspicion symptoms (hostile group), respectively.The findings were compared with those of the control group.Results There were no significant differences, between the depression group and the hostile group, on latencies and amplitudes of late positive potential (LPP) induced by the three types of face expression images, except the amplitude induced by negative face expression image.Compared with the control group, the latencies were extended and the amplitudes were lower in both depression and hostile groups.Within each group, the difference of latencies induced by the three images was not significant.The amplitudes induced by negative face expression image was higher than those induced by positive and neutral face expression images, with significant differences in the hostile group and the control group (P＜0.05) but not in the depression group.Conclusion Changes in latencies and amplitudes of LPP could be an objective indicator in the evaluation of mood disorders of brain traumatic patients.The LPP induced by negative face expression images could be more meaningful for patients mainly with anxiety and depression symptoms.

OBJECTIVETo find the function and functioning mechanism of Yiqi Qingwen Jiedu Heji in resisting influenza immune damage by studying its effect on the expressions of cytokine.

METHODTaking IV FM1 infected mice as its model and doing ELISA (double antibody sandwichenzyme linked immunosorbent assay), we dynamically observed the change of cytokine TNF-alpha, IL-6, IFN-gamma and IL-10 after giving Yiqi Qingwen Jiedu Heji treatment.

RESULT AND CONCLUSIONAfter the mice are infected by influenza virus, their protein expressions of the model group are higher than those of the control group, of which TNF-alpha, IL-6, IFN-gamma reach the peak in three days. The three expressions of Yiqi Qingwen Jiedu Heji treated group are decreased and the decrease becomes remarkable on the third day, compared with those of the model group. However, the expression of IL-10 of the treated group is remarkably increased. It indicates that Yiqi Qingwen Jiedu Heji can resist the expressions of TNF-alpha, IL-6 and IFN-gamma pro-inflammatory cytokine,increase the expression of IL-10, and thus, alleviate inflammatory injury. So the clinical application of such medicine can shorten the course of disease.

Objective: To investigate the current situation of drug supply and determinants of drug shortage in primary health institutions in Anhui province. Methods:Primary health institutions in Anhui province were selected as the main research subjects. One hundred and six (106) primary health institutions from three areas/districts in Anhui province namely northern Anhui,Central Anhui,and Southern Anhui were selected with stratified random sampling as the first sample,and 54 pharmaceutical producing enterprises and 62 pharmaceutical trading enterprises were selected with convenience sampling method as the second sample. The survey was conducted by issuing questionnaires to record views of the respondents to help understand the current situation of drug supply from the first sample and the main de-terminants and solutions of drug shortage from two samples. Results:13% of the primary health institutions still suffer from serious shortage of drug supply; the drug distribution rate varies greatly between units, and 19% of the primary health institutions have a drug distribution rate below 70%,and all primary health institution within the scope of inves-tigation experienced drug shortages. The frequency of choices of determinants of drug shortage were in sequence of or-der:drug demand instability (19.20%), drugs have a new and higher profit alternative (15.94%), etc.; The fre-quency of choices of solutions of drug shortage of primary health institution were in sequence of order:to improve the national list of essential medicines(12.78%),appropriate improvement in efficacy the low-priced varieties(with cura-tive effect) (12.03%),etc. Conclusions:Primary health institutions suffer from drug shortage issue widely,and the reasons for the shortage of drugs are more complicated;the government should continue to implement relevant policies, comprehensively improving the primary health institution drug supply mechanisms in all to prevent drug shortages.

BACKGROUNDThe N400 component of event-related potentials (ERP) has recently drawn widespread attention at home and abroad. This study was to explore the relationship between N400 changes and risperidone treatment and rehabilitation infirst-episode schizophrenia (FES).

METHODSERP component N400 was recorded by Guangzhou Runjie WJ-1 ERP instruments, in 58 FES before and 6 months, 15 months after risperidone treatment, and in 62 normal controls. The patients' syndromes were assessed by Positive and Negative Syndrome Scale (PANSS). And the stimuli are Chinese sentences with matching (congruent) or mismatching (incongruent) ending words.

RESULTSN400 latencies were prolonged, and amplitudes were decreased in Cz, Pz, Fz, C3, C4, in FES compared with in NC, before treatment. The prolonged N400 latencies and decreased amplitudes were negatively correlated with the patients' positive scale and total scale of PANSS. There are significant differences of N400 amplitudes and latencies in 6 months and 15 months follow-up after treatment. Before treatment, 6 months and 15 months after treatment, N400 latencies are 446 ± 35 ms, 440 ± 37 ms, 414 ± 31 ms (F = 9.72, P < 0.01) in incongruent situation; N400 amplitudes are 5.2 ± 4.6 μV, 5.7 ± 4.8 μV, 7.3 ± 5.0 μV (F = 2.06, P > 0.05) in congruent situation, and 8.5 ± 5.9 μV, 10.1 ± 5.0 μV, 11.9 ± 7.0 μV (F = 3.697, P < 0.05) in incongruent situation.

CONCLUSIONSN400 could be used to predict the effects of treatment of schizophrenia to some degree. The linguistic and cognitive impairment in schizophrenia can be improved by antipsychotic drugs.

The fluoritum is used for gynecology frequently and it's for those diseases: kidney yang deficiency, Gong cold sterility, palpitation due to fright, insomnia and dreaminess and cold cough. It's ruled in Chinese Pharmacopoeia (1985 edition) that the fluoritum originates from fluorite which belongs to fluoride minerals. Its main content is CaF2. The colors are of differents grades with purple or green. In the market, there are large differences in quality and it has various colors. Besides of the ruled color of purple and green, white and yellow are also common colors. By digging into and analysis the relevant research literature of fluorite which belongs to fluoride minerals, colors and coloration mechanism of fluorite are summarized in this paper.Natural fluorite is the mineral which has the most species of colors in nature. The different colors of fluorite are mainly caused by the impurity elements. At present, there are mainly about the coloration mechanism of fluorite: rare earth ions (4fN ions), color center, inclusions, crystalline domains or sub microscopic inclusions. The green of fluorite is produced by 570 nm and 305 nm absorption peaks which are caused by Sm2+ and compensated ions Na+ centers generated color center. The yellow of fluorite is produced by the joining of transition element, resulting in the formation of charge transfer between the crystal ions and the formation of O2-O32- ion molecule.The black of fluorite, mainly was attributed to the existence of a higher degree of evolution of organic matter. In this passage,suggestions for modification of the properties of fluoritum in Chinese Pharmacopoeia are put forward.
