Asthma is a common disease with recurrent onset which severely affects patients' quality of life.Acupuncture can improve pulmonary functions in asthma patients and thus treat this disorder.To summarize the status of acupuncture treatment for asthma,we have collected clinical literatures published in the recent 10 years and analyzed the influence of acupuncture on pulmonary functions in asthma patients from the aspects of frequently used points,needling techniques,manipulation and mechanisms to provide references for treating asthma with acupuncture.

The HPLC fingerprint determination method of Jinzhen oral solution was established to provide a new method for quality control of Jinzhen oral solution. RP-HPLC was used for phenomenex Luna C18 (4.6 mm x 250 mm, 5 μm) chromatographic column, with 0.1% H3 PO4 water solution and acetonitrile as the mobile phase for gradient elution. The detection wavelength was 280 nm. HPLC fingerprint of Jinzhen oral solution was established to identify 17 common peaks in Jinzhen oral solution. The similarity of fingerprints of 10 batches of finished products was more than 0. 90. The established HPLC fingerprint has a better precision, reproducibility and stability, and can be applied in quality control of Jinzhen oral solution.

To study the transport mechanisms of drugs for transplacental treatment of fetal tachyarrhythmia, MDCKII-BCRP and MDCKII cell models was used. MDCKII-BCRP and MDCKII cell monolayer model was used to investigate the bi-direction transport of sotalol, propranolol, propafenone, procainamide and flecainide. Drug concentrations were measured by HPLC-UV or chemiluminescence. The apparent permeability coefficient (P(app)), efflux rate (R(E)) and net efflux rate (R(net)) were calculated. Drugs with R(net) greater than 1.5 were further investigated using cellular accumulation experiments with or without a BCRP inhibitor. The R(net) of sotalol, propranolol, propafenone and procainamide were less than 1.5, while R(net) of flecainide with concentrations of 20 and 5 μmol x L(-1) were 1.6 and 1.9, respectively. The results showed that the transport of flecainide on MDCKII-BCRP cell monolayer could be mediated by BCRP; and the affinity increased when the concentration of flecainide decreased. Cellular accumulation experiments further suggested that accumulation of flecainide in MDCKII-BCRP cells was significantly lower than that in MDCKII cells in a concentration-dependent manner. BCRP inhibitor quercetin (50 μmol x L(-1)) significantly increased the accumulation of flecainide in MDCKII-BCRP cells (P < 0.05). Our preliminary data showed that flecainide but not sotalol, propranolol, propafenone or procainamide can be a substrate of BCRP. Thus the effect of flecainide may be affected by the BCRP in the maternal placental trophoblast membrane layer when treating fetal tachyarrhythmia.

Objective To observe the effect of Ti-6AL-4V particles on morphological and func- tional changes of osteoclast in vitro.Methods Mature osteoclasts separated from New Zealand Rabbits were cultured on glass slices and cortical bone slices.The experimental group was stimulated by Ti-6AL- 4V particles at concentration of 0.1 mg/ml.The cells were stained with TRAP at different culture time to observe the morphological variety.The bone resorption pits on bone slices were stained by toluidine blue and the resorption areas analyzed by computer image analysis software.Results Osteoclasts phagocy- tosed the particles,with irregular shapes,deeper TRAP stain and earlier apoptosis.Stimulation by Ti- 6AL-4V particles brought about larger area of bone absorption lacuna.Conclusion Osteoclasts have the ability to phagocytose Ti-6AL-4V particles,which leads to morphological and functional changes and enhances bone resorption.

The content of the asarone submicro emulsion injection was determind by HPLC method, and thereby a quality evaluation method was established based on indexes of pH value, particle size, peroxide value, methoxy aniline values, free fatty acid, lysophosphatidylcholine, visible foreign substances, insoluble particle, sterility, bacterial endotoxin and impurities, etc. The results showed that the injection exhibited uniform physical appearance and all the products were in milkwhite liquid. The content of the three batches products were respectively 102.9%, 100.8%, 97.70% of the labeled amount, with mean particle size of 210-250 nm, and other indexes all met with the standards. The reserved samples showed no obvious change in terms of detection indexes and indicated good stability after the accelerated stability test and long-term stability for 12 months. The quality evaluation method established in this study could be applied to quality control and stability investigation of asarone submicron emulsion injection, which laid a basis for further clinical research and application.

The mutual influence of lead and cadmium ions on “in-situ” bismuth film coated glassy carbon electrode was demonstrated using different concentration target ions by changing ratio between Pb2+ and Cd2+. It is found that the presence of coexisting ions can have an influence on the detection of target ions. Especially for the detection of Cd2+, the existence of Pb2+ can be beneficial for the deposition of Cd due to the more positive deposition potentials. And the analytical performances of Cd2+and Pb2+ were obtained. The detection limit is 0. 5 μg/L towards Pb2+ with a linear range from 1-80 μg/L using 60 s deposition time. The resulting calibration plots of Cd2+ are linear over the range from 1-25 and 30-200 μg/L with the detection limit of 1 μg/L using 120 s deposition time. The bismuth film was finally employed to determine the Pb2+and Cd2+in real sample with good satisfied results.

Objective To investigate the memory monitoring ability in patients with idiopathic generalized epilepsy (IGE) and explore the mechanism of the memory impairment.Methods The feeling of knowing (FOK) paradigm of episodic memory (EM) and semantic memory (SM) were established and subsequently administered in 31 patients with IGE (IGE group) and 30 healthy controls (HC group) participants who were matched in age,sex and educational level.Results Compared with HC group (feeling of knowing of episodic memory (FOK-EM) FOK accuracy (85.29± 16.84) ％;feeling of knowing of sematic memory (FOK-SM) recall (76.61± 18.66) ％),the FOK-EM FOK accuracy ((64.03± 22.10) ％) and FOK-SM recall ((53.27±26.91) ％) in IGE group were significantly decreased(t=-4.215,P＜0.01;t=-3.677,P＜0.01).The correct judgment and correct recognition of FOK-EM ((51.16±32.93) ％) and the false judgment and correct recognition ((21.07±24.38) ％) of FOK-EM in the IGE group were significantly different with the HC group (the correct judgment and correct recognition of FOK-EM:(79.34±27.26)％ and the false judgment and correct recognition of FOK-EM:(2.45±5.38) ％;t=-3.634,P＜0.01;t=4.149,P＜0.01).Most importantly,the false judgment and correct recognition of FOK-EM were correlated with the Digital Span Test,Vocabulary Fluency Test and the Stroop effect in IGE group (r=-0.309,P＜0.05;r=-0.355,P＜0.01;r=-0.354,P＜0.05;r=0.602,P＜0.01).Conclusion The results show that the IGE group made less accurate metamemory monitoring than the HC group by underestimating their memoU performance on FOK-EM,whereas the semantic metamemory monitoring is not impaired in IGE group.More importantly,the impairment of memory monitoring was correlated with the deficit of executive function,indicating that this mechanism can be an influential factor of memory disorder in IGE.It also indicates that the episodic and semantic metamemory monitoring depend on different neural networks.
