OBJECTIVE:To optimize the placement of extra-machine medicines in the automated pharmacy and establish a ra-pid dispensing area to shorten medicine dispensing time. METHODS:12 588 prescriptions made within one week were collected from the outpatient pharmacy of our hospital,in which 29 kinds of extra-machine medicines used frequently were clustered on the basis of Pearson correlation coefficients. The extra-machine medicines used at a higher frequency were arranged in the storage posi-tions near to the medicine dispensing window,and those related to the above-mentioned medicines were stored in the positions adja-cent to them,thereby a rapid dispensing area was established. The effect of the above-said method was evaluated by comparing the time it took for the pharmacist to dispense medicines one week before and after the establishment of the rapid dispensing area. RE-SULTS:29 kinds of extra-machine medicines were clustered into 4 major categories,and stored in 4 positions in the rapid med-icine dispensing area respectively,and then the position codes were assigned. After the rapid dispensing area was established,the average single prescription dispensing time for the pharmacist decreased by about 9 s (40.43 s vs. 31.43 s,P<0.01). CONCLU-SIONS:The establishment of the rapid dispensing area based on cluster analysis method has increased the efficiency of dispensing medicines in the outpatient pharmacy of our hospital.

Objective In attempt to improve the reconstruction of small defects in the facial and frontal regions, we developed a modified radial artery perforator-based free flap. Methods The free proxi-mal radial forearm flap was based on the distal perforator of the radial artery and the concomitant radial vein. The vascular pedicle passed through deep fascia. The free flap was transferred to repair the defects of the fa-cial and frontal regions. Results In 6 patients with frontal defects and 4 patients with facial defects, all flaps survived completely. After following up for 6-12 months, flaps underwent plastic surgery to become thin-ner. The flaps of 10 cases were good in skin texture and color at recipient sites. The scars were cosmetically acceptable. The superficial sensibility recovered well. Conclusion A modified radial artery perforator-based free flap was useful in coveting small defects of the facial and frontal regions.

The severe fever with thrombocytopenia syndrome virus (SFTSV) is a new member in the genus Phlebovirus of the family Bunyaviridae identified in China. The SFTSV is also the causative pathogen of an emerging infectious disease: severe fever with thrombocytopenia syndrome. Using immunofluorescent staining and confocal microscopy, the intracellular distribution of nucleocapsid protein (NP) in SFTSV-infected THP-1 cells was investigated with serial doses of SFTSV at different times after infection. Transmission electron microscopy was used to observe the ultrafine intracellular structure of SFTSV-infected THP-1 cells at different times after infection. SFTSV NP could form intracellular inclusion bodies in infected THP-1 cells. The association between NP-formed inclusion bodies and virus production was analyzed: the size of the inclusion body formed 3 days after infection was correlated with the viral load in supernatants collected 7 days after infection. These findings suggest that the inclusion bodies formed in SFTSV-infected THP-1 cells could be where the SFTSV uses host-cell proteins and intracellular organelles to produce new viral particles.

OBJECTIVE:To investigate the characteristics and factors of ADR caused by Chinese patent medicine(CPM)and to provide reference for rational drug use and safety evaluation in the clinic. METHODS:158 cases of ADR caused by CPM collect-ed from our hospital during Jan.2009-Dec.2014 were analyzed. RESULTS:The occurrence of ADR caused by CPM was related to patient’s age,route of administration,category of drugs,irrational drug-use and so on. The incidence of ADR in patients over the age of 60 was the highest (31.01%),the largest number of ADR were caused by intravenous injection (79.11%),ADRs were most likely caused by blood-regulating preparation and dissipate blood stasis preparation (79.75%);ADR manifested as lesion of skin and its appendents(43.01%),followed by gastro-intestinal injury(16.06%)and whole-general injury(10.36%). The severe ADR was anaphylactoid reaction;after symptomatic treatment,the prognosis is good. CONCLUSIONS:According to syndrome differentiation and individual difference,CPM should be used rationally,and great importance should be attached to drug use moni-toring to reduce the incidence of ADR.

The severe fever with thrombocytopenia syndrome virus (SFTSV) is the causative pathogen of an emerging infectious disease severe fever with thrombocytopenia syndrome and a new member in the genus Phlebovirus of family Bunyaviridae. Immune responses and pathological lesions in SFTSV-infected Balb/C mice and hamsters were evaluated by inoculation of SFTSV at 105 TCID50 or 103 TCID50 per animal through four different routes of infection, including intravenous, intramuscular, intraperitoneal, and intracerebral injections. The vehicle control groups were also included. At different time points after the inoculation blood and plasma samples were collected. Blood cell counts, blood viral RNA copies, and plasma antibodies were detected by automatic blood cell counters, real-time PCR, and luminex assays, respectively. At two weeks post inoculation, the animals were sacrificed. Tissues including heart, liver, spleen, lung, kidney, intestine, muscle, and brain, were collected for pathological analyses. Results showed that the SFTSV could infect Balb/C mice and hamsters with SFTSV-specific immunoglobulin (Ig) M and IgG antibodies detected in plasma samples on day 7 post inoculation. The SFTSV-specific IgM levels peaked on day 7 post inoculation and then decreased, whereas the SFTSV-specific IgG levels started to increase on day 7 and then peaked on day 14 post inoculation. Pathological analyses indicated significant pathological lesions in liver and kidney tissues. In conclusion, SFTSV could can infect different strains of rodent animals and cause similar immunological and pathological responses.
