Objective To preparare the ?-carotene microemulsion (?-cm)from Dunaliella salina and study its stability.Methods The influences of some factors on the stability of ?-cm were studied.These factors included light,temperature,air(oxygen),storing time and so on.Results The appearance,color,Zeta potential,volume-Wt diameter and K_(e) were unchanged,but content of ?-cm was decreased with higher temperature(40℃)or stronger light(4500?500L_(x)).Conclusion The preparation should be stored at low temperature and keep away from light.Under this circumstance,the ?-cm was stable for more than 12 months.

Objective To provide a basis for further exploration of Dunaliella Salina by determining the main active components in the extract of Dunaliella salina.

Objective To evaluate the effectiveness and safety of tanreqing injection to children bronchial pneumonia.Methods PubMed,Ovid,CNKI,and data retrieval system of all places were searched to identify relevant studies from 2003 to November of 2014.The final documents were examined with inclusive and exclusive criteria.Results were pooled with meta-analysis on RevMan software to assess the efficacy of tanreqing injection to children bronchial pneumonia.Results The database was derived from 13 qualified studies that included a total of 1479 patients.Meta analysis showed that,compared to the control group,tanreqing injection treatment group resulted in higher effective rate [OR =2.96,95％ CI (2.22,3.96),P ＜0.01],shorter time of recovering the normal temperature [MD----0.53,95％ CI (-0.77,-0.29),P ＜ 0.01],shorter time of disappearance of cough [MD =-1.25,95％ CI (-2.14,-0.37),P ＜0.01],shorter time of lungrale [MD=-1.00,95％ CI(-1.4,-0.6),P ＜0.01],and shorter time of hospitalization time [MD =-1.35,95％ CI (-1.83,-0.86),P ＜ 0.01].Significant difference was observed between control and treatment groups.Conclusions This study showed that tanreqing injection appeared to be more effective for children bronchial pneumonia.However,methodology showed low quality.The efficacy needs high-quality clinical trials to verify.

OBJECTIVE:To provide a reference for rational clinical application of Reduning injection. METHODS:The rele-vant information about the patients who sought treatment in our hospital in 2014 and used reduning injection were collected to make statistical analysis to the age,dosage,course of treatment,frequencies,etc. RESULTS:Among the above-mentioned patients,the number of males was more than that of females,children under 10 years old accounted for 36.10%,47.54%of patients received re-duning injection for a treatment course of over five days,and 14.99% of patients failed to wash the infusion tube before injection. CONCLUSIONS:Irrational clinical application of reduning injection exists. The administration and dosage should be standardized and the dosage for children under three years old as specified in the label be detailed to reduce and avoid the occurrence of adverse drug reaction so as to ensure the safety of drug use by patients.

Objective:To analyze the effects of enhanced recovery after surgery(ERAS) concept on anesthetic agents in our hos-pital in order to provide evidence for rational drug use. Methods:The patients received ERAS care and surgery from departments of o-torhinolaryngology,gynecology and urology during June and December in 2016 were selected into ERAS group. Meanwhile, the pa-tients received usual care and routine operation were selected into the traditional group. Anesthetic agents of the two groups were then analyzed. Results:The anesthetic agents costs, the usage rate and expenses of patient controlled analgesia pump and the total drug costs of ERAS groups were significantly lower than those of the traditional groups(P<0.05 or P<0.01). Conclusion:With the de-velopment of ERAS concept, the patients can receive good diagnosis and treatment. Meanwhile, anesthetic agents costs, total drug costs and drug proportion decrease as well.

Acute organophosphorus pesticide poisoning (AOPP) is one of the common critical diseases.In order to improve the rate of clinical cure, in recent years, many new treatment methods in clinical are recognized.In this paper, we will make a overview from the mechanism of AOPP, the application of classical drug cholinesterase reactivators, anticholinergicdrugs, other new applications such as fat emulsion for AOPP and blood purification therapy, combination therapy of Chinese and Western medicine, comprehensively elaborate the application of these drugs and treatment methods in clinical and therapeutic effect.

Aim To determine the effective compo-nents of Semen Ziziphi Spinosae for sedative-hypnotic and its mechanism. Methods The extraction of Se-men Ziziphi Spinosae and the rat brain homogenates were prepared. High concentrations of Diazepam com-petitively replaced the ligand compounds of Semen Ziz-iphi Spinosae combining BDZ receptor in brain tissue, and all the compounds with sedative and hypnotic effects were collected and identified by HPLC and LC-MS technique, as the compounds extracted from the brain tissue were administered with Semen Ziziphi Spi-nosae. The brain tissue was administered with Diaze-pam, and with Semen Ziziphi Spinosae and Diazepam. Results The HPLC chromatograms show that the peak time of BDZ receptor ligand compounds was 2. 71 min and 46. 87min, when compared with Diazepam. And the LC-MS chromatograms display the relative molecu-lar weight of the ligand compounds was 274. 28 m/z, 453. 34 m/z,496. 34 m/z and 608. 38 m/z respective-ly. According to the fingerprint of Semen Ziziphi Spi-nosae, these compounds may be fatty acid substances and lupine pill triterpene compounds. Conclusions On the basis of the principle of receptor ligand bind-ing, we established a way to quickly analyze and iden-tify the role of natural products in the same drug target compounds. The method not only can clearly define the effective components of natural products, but also clar-ify the mechanism of action of the compounds. The ac-tive ingredient of calm hypnosis in Semen Ziziphi Spi-nosae may be fatty acid substances Palmitic acid ( C16 H32 O2 ) and lupine pill triterpene compounds Alphitolic acid( C30 H48 O4 ) and Spinosin( C28 H32 O15 ) . They exert their sedative and hypnotic effects by combining with BDZ receptor, and the research has laid a theoretical foundation for the further study about mechanism of Se-men Ziziphi Spinosae.

OBJECTIVETo evaluate the semen quality of the donors.

METHODSThe semen parameters of the primary samples of 512 donors were examined following the World Health Organization (WHO) guide and computer-aided sperm analysis (CASA, product by Harmilton Thorne) system.

RESULTSOf the 246 (246/512, 48%) donors with potential fertility, only 146 (146/512, 28.5%) came up to the semen standard set by the Chinese Ministry of Health, while 266 (266/512, 52%) were below the WHO reference values of semen parameters.

CONCLUSIONRepeat semen analyses may increase the success rate in screening semen donors. The semen quality of the donors suggests that it is necessary to pay more attention to male reproductive health.

OBJECTIVETo observe sperm motion parameters in pre-freeze and post-thaw semen samples using computer-assisted sperm analysis (CASA) system.

METHODSSemen analyses of 238 samples before freezing and after thawing were separately performed by Hamilton-Thorne Sperm Analyzer.

RESULTSSperm motility in post-thaw samples was significantly decreased. There was significant correlation and difference between pre-freeze and post-thaw samples in sperm motion parameters, including average path velocity (VAP), straight line velocity (VSL), curvilinear velocity (VCL), amplitude of lateral head displacement (ALH), straightness (STR) and linearity (LIN), except heat cross frequency (BCF). The percentage of sperm movement velocity parameters (VAP, VSL and VCL) and moving pattern parameters (ALH) significantly decreased, while that of LIN and STR significantly increased in post-thaw samples.

CONCLUSIONCASA system is of clinically applied value and is a useful tool for evaluating sperm motion parameters in pre-freeze and post-thaw semen samples.
