Objective To observe the clinical efficacy of amiodarone combined with botulinum toxin A in the treatment of hemifacial spasm.Methods Sixty-five patients with hemifacial spasm were randomly divided into amiodarone(n=33)and control(n=32)group.In the amiodarone group,oral amiodarone and local intramuscular injection of botulinum toxin A were administered.In the control group,only local intramuscular injections of botulinum toxin A was performed.The clinical efficacy was evaluated according to the Cohen rating on the 1st,4th,16th,32nd week.Results The Cohen rating in amiodarone group was significantly better than control group on 4th,16th,32nd week(P<0.05).The complete remission in amiodarone group was significantly higher than control group on 4th,16th,32nd week(75.8% vs.43.8%,81.8% vs.12.5%,81.8% vs.6.2%,all P <0.05).The total effective rate in amiodarone group was significantly higher than control group on 16th,32nd week(97.0%vs.75.0%,93.9% vs.65.6%,all P<0.05). There was one case of recurrence in control group on 4th week,while there was no recurrence in amiodarone group.The recurrence in control group on 16th,32nd week was higher than amiodarone group(56.3 % vs.0.0 %,65.6% vs.12.1%,all P<0.05).There was no signigicant difference in adverse reactions between amiodarone group and control group(24.2%vs.18.8%).Conclusion Combination of amiodarone and botulinum toxin A is more effective than botulinum toxin A alone in the treatment of hemifacial spasm.

Objective To study the effect of Fructus Aurantii Immaturus Decoction on defecating function of constipated mice.Methods Constipation mice models were induced by Compound Diphenoxylate.Defecating effects of Fructus Aurantii Immaturus on normal and constipation mice were observed.Results Middle and high dose of Fructus Aurantii Immaturus decoction could increase impelling rate of small intestine,shorten the time for the first dark stools(P<0.05 or P<0.01).and add the amount of dark stools within 6 hours(P<0.01).Conclusion Fructus Aurantii Immaturus has the functions of loosening bowel to relieve constipation.

Objective To investigate and analyze the risk factors,morbidity and mortality rates of multiple organ dysfunction syndrome (MODS) after multiple trauma.Methods The clinical data of all 155 patients with multiple trauma admitted to our ICU from Sep 2008 to Jun 2011 were retrospectively analyzed,including treatment,injury severity score (ISS) and its relationship with MODS.Results The morbidity of MODS among all 155 patients was 18.7％ (29/155).There were 3,7 and 19 patients died due to multiple trauma in 39 ISS ＜ 16,58 ISS 16-25,and 58 ISS ≥25 cases respectively.The morbidity of MODS was significantly higher in patients with ISS ≥25 ( x2 =12.321,P =0.002) than in others.There were 15 cases with MODS and 28 cases without MODS died respectively in multiple trauma patients ( x2 =10.236,P =0.001 ).Conclusion MODS is the important reason for death in multiple trauma patients.It is pivotal to actively deal with primary trauma to avoid the second insult to the patients and support vital organs early in order to improve the prognosis of multiple trauma.

The serum levels of soluble E selectin (sE selectin) and soluble vascular cell adhesion molecule 1 (sVCAM 1) were determined by ELISA in impaired glucose tolerance (IGT) group (62 cases), normal glucose tolerance (NGT) group (24 subjects), and diabetes mellitus group (23 cases). Serum sVCAM 1 level in the IGT group was significantly higher than that in the NGT group (P

Lung cancer, with growing morbidity and mortality worldwide, is one of the most malignant tumors, representing a significant threat to human health and life.The application of next-generation genomic technologies has offered a more comprehensive look at the mutational landscape across the different subtypes of nonsmall cell lung cancer (NSCLC).A number of recurrent mutations such as TP53, KRAS, and epidermal growth factor receptor (EGFR) have been identified in NSCLC.While targeted therapeutic successes have been demonstrated in the therapeutic targeting of EGFR and ALK, the majority of NSCLC tumors do not harbor these genomic events.This review looks at the current treatment paradigms for lung adenocarcinomas (LAC) and squamous cell carcinomas, examining genomic aberrations that dictate therapy selection, as well as novel therapeutic strategies for tumors harboring mutations in KRAS and TP53 which, to date, have been considered undruggable.A more thorough understanding of the molecular alterations that govern NSCLC tumorigenesis, aided by next-generation sequencing, will lead to targeted therapeutic options expected to dramatically reduce the high mortality observed in lung cancer.

Macrophages are major effecter cells of nonspecific immune response,the polarization of which plays a great role in inflammation,repairing and angiogenesis.According to functional phenotypes,macrophages can be polarized to classically activated type (M1),which could promote angiogenesis,and alternatively activated type (M2),which could inhibit angiogenesis.The proportion of M1/M2 could modulate the growth of choroidal neovascularization (CNV).Under the conditions of aging and injury within the retina,macrophages may polarize to M2,which could generate several proangiogenic factors,initiating and promoting the formation of angiogenesis and fibrous scar.Therefore,regulation of macrophage polarization is expected to inhibit angiogenesis and provide new insight for treatment of CNV.

Objective Tamarix ramosissima is the host plant of Cistanche tubulosa. The chemical cons-tituents of T. ramosissima were studied in order to improve the development of culture base of C. tubulosa and look for the base for exploitation of T. ramossisma. Methods Various chromatographic techniques were employed for the isolation and purification of the constituents including silica gel, Sephadex LH-20, and preparative HPLC. The structures of compounds were elucidated by chemical and spectral analyses (IR, UV, NMR, and MS). Results Twelve compounds have been isolated from the tender wattle of T. ramosissima, their structures were elucidated as aleuritolic acid (D-friedoolean-14-en-3-ol-28-oic acid, Ⅰ), aleuritolonic acid (D-friedoolean-14-en-3-one-28-oic acid, Ⅱ), rhamnocitrin (Ⅲ), ellagic acid-3, 3′-dimethyl ether (Ⅳ), rhamnetin (Ⅴ), kaemferol (Ⅵ), isoferulic acid (Ⅶ), aromadendrin (Ⅷ), (2?,3?)-dihydrorhamnetin (Ⅸ), quercetin (Ⅹ), 7, 4′-dimethoxykaemferol (Ⅺ), 3-methoxykaemferol (ⅩⅡ). Conclusion Among these compounds, Ⅰ, Ⅱ, Ⅳ, Ⅴ, Ⅷ, Ⅸ, and ⅩⅡ are isolated from the plants of Tamarix L. for the first time.

Objective To explore the feasibility of ultrasonic examination in the strain(S) and strain rate(SR) of carotid artery atheromatous plaque, and the distribution of S and SR of the atherosclerotic plaques. Methods Tissue velocity imaging(TVI) was used in 26 cases of coronary artery disease(CAD),and 35 atherosclerotic plaques in the carotid artery were found.The peak values of displacement, S and SR in different plaque sites were obtained with Q-analysis software. The estimation of S and SR of same sites was acquired in different parametric settings, including S length, S reject and S scale. Results Different parametric settings had no influence upon the estimation of S and SR. However, significant difference of S and SR could be found in different plaque sites, such as the shoulder, the surface of fibrous cap and the base and it was the same case among different acoustic plaque types. S and SR distribution patterns were similar between angina pectoris group and old myocardial infarction group; yet they were significantly different between acute myocardial infarction group and the former two groups. Conclusions TVI technique and ultrasonic Doppler-based strain imaging method could be used in carotid arteries. Strain concentrated mainly on the surface of fibrous cap and the plaque shoulder. SR of plaque shoulder among three acoustic plaque types was different. From the surface to the base axially, S and SR decreased gradually.
