Objective To investigate the epidemiological characteristics of adverse drug reactions (ADRs) induced by Chinese herbal injection for tonify, and provide reference for safety evaluation and rational use. Methods The ADR cases that issued on the domestic medicinal periodicals from 1972 to 2011 in China were collected comprehensively to build a database, and analyzed by statistic methods. Results Totally 233 ADR cases involving 7 different kinds of Chinese herbal injection for tonify were collected, in which 86 cases weighted the most were related to Huangqi Injection. Chinese herbal injection for tonify may induce multiple systematic ADRs. The incidence of respiratory damage was 27.0%(80 cases), which was dominated in the ADRs. The incidence of ADRs had no difference between the genders (male was 117 cases, 50.2%, and female was 116 cases, 49.8%), and the average age of patients was (51.40±16.67) years old. ADRs often occurred within half an hour after the start of infusion (64.5%). The diseases of patients mostly were cancer (19.3%), coronary heart disease (15.9%), and hypertension (6.0%), etc. Only 76 cases mentioned the combination therapy, which mainly combined with the drugs of antibiotics, other traditional Chinese medicines and vitamin. Conclusion ADRs of Chinese herbal injection for tonify are always induced by drug combinations, inappropriate medication, and other factors. To use Chinese herbal injection more rational and enhance prevention awareness may be the key to reduce the occurrence of ADRs.

Objective To evaluate the molluscicidal effect of 2 kinds of shamingdan in lab. Methods Under constant temperature (25?1) ℃, the studies were carried out by using different concentrations(dosages) of molluscicide, shamingdan, in various methods of immersing, spraying and dusting power, and the molluscicidal effects were compared with 50% wettable powder of niclosamide ethanolamine salt(WPN). Results The 48-hour's LC_ 50(s) of 4% shamingdan granular formulation and 50% shamingdan soluble powder were 0.1752 mg/L and 0.2713 mg/L, respectively, which were similar to that of 50% WPN. In spraying and dusting powder experiment, the 7-day's LC_ 50(s) were 3.0418, 0.1623 g/m~2 and 2.8752, 1.1101 g/m~2, respectively, and the 50% shamingdan soluble powder was better than 4% shamingdan granular formulation and 50% WPN. Conclusions The molluscicidal effect of 2 kinds of shamingdan using immersing is better than that using spraying and dusting. The molluscicidal effect of the 50% shamingdan soluble powder is remarkably better than that of the 4% shamingdan granular formulation and 50% WPN.

Objective To evaluate the anticoagulant and antineoplastic activities of chemically modified low-molecular-weight heparin (LMWH). Methods LMWH obtained by splitting unfractionated heparin (UFH) with sodium periodate oxidation and sodium borohydride reduction was subjected to acetylation catalyzed by DCC and DMAP to produce acetylated LMWH (ALMWH). The anticoagulant activity of ALMWH was determined in mice, and its antiproliferative and anti-invasion activities was assessed in human breast cancer cells MDA-MB-231 and MFC-7. Results The anticoagulant activity of LMWH was decreased significantly after acetylation. The concentrations of commercial LMWH* and ALMWH for doubling the coagulation time (CT) were 33.04 μmol/L and 223.56 μmol/L, respectively, and the IC50 of ALMWH for doubling CT was 6 times of that of LMWH*. ALMWH and LMWH at 0.1, 0.3, 0.9, 2.7 and 8.1 mmol/L both significantly inhibited the proliferation of MDA-MB-231 and MCF-7 cells in a concentration-dependent manner, but ALMWH produced stronger inhibitory effects. The IC50 of LMWH and ALMWH for inhibiting cell proliferation was 3168.4 μmol/L and 152.6 μmol/L in MCF-7 cells, and 12299.6 μmol/L and 22.2 μmol/L in MDA-MB-231 cells, respectively. ALMWH and LMWH all markedly suppressed the invasion of MDA-MB-231 cells with comparable effects. Conclusion Chemical modification of structure can endow LMWH with a low anticoagulant and high antiproliferative activities.

The laterodorsal tegmentum (LDT) is a brain structure involved in distinct behaviors including arousal, reward, and innate fear. How environmental stimuli and top-down control from high-order sensory and limbic cortical areas converge and coordinate in this region to modulate diverse behavioral outputs remains unclear. Using a modified rabies virus, we applied monosynaptic retrograde tracing to the whole brain to examine the LDT cell type specific upstream nuclei. The LDT received very strong midbrain and hindbrain afferents and moderate cortical and hypothalamic innervation but weak connections to the thalamus. The main projection neurons from cortical areas were restricted to the limbic lobe, including the ventral orbital cortex (VO), prelimbic, and cingulate cortices. Although different cell populations received qualitatively similar inputs, primarily via afferents from the periaqueductal gray area, superior colliculus, and the LDT itself, parvalbumin-positive (PV) GABAergic cells received preferential projections from local LDT neurons. With regard to the different subtypes of GABAergic cells, a considerable number of nuclei, including those of the ventral tegmental area, central amygdaloid nucleus, and VO, made significantly greater inputs to somatostatin-positive cells than to PV cells. Diverse inputs to the LDT on a system-wide level were revealed.
