Objective To prepare chitosan (CS)-compound Yizhihao-nanoparticles (NP) and to investigate its antibacterial activity. Methods CS NPs were formed by the incorporation of CS and Na3PO4. CS-compound Yizhihao NPs were prepared by ion-cross-linking. The particle sizes and surface charges of CS NPs were determined by Malvern Zetasizer 1000-HAS and atomic force microscope (AFM), respectively. The antibacterial acitivity of CS-compound Yizhihao-NPs was studied in vitro and compared with that of compound Yizhihao powder. Results Malvern Zetasizer 1000-HAS and AFM demonstrated that the diameter of CS-compound Yizhihao NPs was (137.00±14.28)nm and CS NPs had (16.90±1.32)mV positive surface charges. The minimal inhibitory concentrations (MIC) of CS-compound Yizhihao NPs on Staphylococcus aureus,Pneumococcus,β-hemolytic streptococcus, and Escherichia coli were 1:32,1:32,1:16,and 1:2,respectively. The minimal bactericidal concentrations (MBC) of CS-compound Yizhihao-NPs on Staphylococcus aureus,Pneumococcus,β-hemolytic streptococcus, and Escherichia coli were 1:16,1:16,1:8, and 1:2,respectively. The antibacterial efficacy of CS-compound Yizhihao-NPs to Staphylococcus aureus,Pneumococcus,and β-hemolytic streptococcus had been improved significantly (P<0.05). Conclusion CS-compound Yizhihao-nanoparticles have obvious antibacterial activity to the Staphylococcus aureus,Pneumococcus,and β-hemolytic streptococcus,which lays the experimental foundation for new preparation of traditional Chinese medicine in future research.

Obstructive sleep apnea (OSA),the most common type of sleep disordered breathing was closely associated with the occurrence of ischemic stroke.It has been demonstrated that OSA is an independent risk factor for ischemic stroke.Its pathogenic mechanism includes atherosclerosis,coagulation abnormalities and cerebral hemodynamic changes caused by long-term periodic hypoxia hypoxemia and hypercapnia.The prognosis of ischemic stroke patients with OSA is poor.Therefore,it needs to be treated early to avoid further damage to brain tissue and reduce the mortality.

Large amounts of clinical studies and epidemiological data have confirmed that obesity is closely related to the development and progression of endometrial cancer.The mechanism of the endometrial cancer may be involved estrogen,insulin,insulin-like growth factor,leptin,adiponectin,resistin fat factor, inflammatory factors and so on.

Objective:To observe the effectiveness and security of piperacillin sodium/sulbactam sodium in the treatment of bacte-rial infections and perform the pharmacoeconomics evaluation. Methods: Totally 126 patients with hand trauma bacterial infections were divided into the control group and the treatment group. The control group was given piperacillin sodium/tazobactam sodium 2. 5g, ivd, bid, while the treatment group was treated with piperacillin sodium/sulbactam sodium 1. 25g, ivd, bid. After 14-day treatment, the clinical therapeutic effect and adverse reactions of the two groups were observed, and the cost-minimization analysis was carried out. Results:The effective rate of the treatment group was 93. 65%while that of the control group was 92. 06%(P>0. 05). The bac-terial clearance rate of the treatment group was 96. 83%while that of the control group was 95. 24% (P>0. 05). The incidence of ad-verse reactions of the treatment group was 4. 76% (3/63) while that of the control group was 9. 52%(P>0. 05). The cost-effective-ness of piperacillin/sulbactam was significantly lower than that of the control group (P<0. 05). Conclusion: The effectiveness and safety of the two groups show no obvious differences in the treatment of hand trauma bacterial infections, and both have good antibacte-rial effect with low incidence of adverse reactions. For the better economic benefits, piperacillin /sulbactam is worthy of promoted ap-plication.

Objective To observe the effect of external fixator combined with limited internal fixation in the treatment of complex ankle fractures.Methods According to the digital table,65 patients with complex ankle fracture were randomly divided into treatment group(33 cases) and control group(32 cases).The treatment group was treated with external fixator combined with limited internal fixation,the control group was treated with internal fixation.All patients were followed up for 5 to 20 months.The curative effect and incidence rate of complication of the two groups were observed.Results The excellent rate of the treatment group was 84.85%,which was higher than 62.50% of the control group,the difference was statistically significant(x2=4.20,P<0.05).The incidence rate of complications in the treatment group was 3.03%,which was lower than 18.75% of the control group,the difference was statistically significant(x2=4.18,P<0.05).Conclusion External fixator combined with limited internal fixation can effectively treat complex ankle fractures,the method can not only make patients satisfied with the reduction effect,but also the internal fixation complications such as infection are minimized,the clinical value is extremely high,it is worthy of wide application.

Objective To observe the clinical efficacy of scalp acupuncture plus body acupuncture in treating diarrhea-predominant irritable bowel syndrome (D-IBS). Method Totally 122 D-IBS patients were randomized into a scalp acupuncture group (41 cases), a body acupuncture group (41 cases), and a combined group (40 cases). The scalp acupuncture group was intervened by acupuncture at the Stomach and Intestine Zones on the head; the body acupuncture group was by ordinary body acupuncture; the combined group was by both scalp acupuncture and body acupuncture. The symptom score of traditional Chinese medicine (TCM) was evaluated prior to the treatment, at the end of the first and second treatment courses, and after the whole intervention; the clinical efficacies were also compared among the three groups. Result The symptom scores of the combined group were significantly lower than that of the scalp acupuncture group and body acupuncture group respectively at the end of the second treatment course and after the whole intervention (P<0.05); after the whole intervention, the cured and markedly-effective rate was 62.5% in the combined group, significantly higher than 24.4% in the scalp acupuncture group and 29.3% in the body acupuncture group (P<0.05). Conclusion Scalp acupuncture plus body acupuncture can produce a satisfactory clinical efficacy in treating D-IBS, better than body acupuncture or scalp acupuncture alone; its advantages include rapid onset of action, significant effect, and reducing intestinal inflammation, etc.

Objective] Summarize the experience of diagnosis and treatment of plasma cell mastitis by Gu ’s surgery department. [Method] By collecting medical records, from the teachers, pathogenesis, to summarize the inheritance and development of diagnosis and treatment of plasma cell mastitis by Gu ’s surgery department three generations, according to the present situation, analysis of the problems existing in the treatment of the disease. [Results] The disease was first discovered and reported by Dr.Gu Bohua in the domestic.Gu’s surgery department gradually gropes for a set of solution method in treatment of plasma cell mastitis after three generations from the treatment based on the external therapies in the initial, to later, internal and external therapies, at present based on the internal therapies. Clinical studies have found that the internal and external therapies have advantages of high cure rate, short treatment time, but the scar is larger, while the internal therapies in the long treatment cycle achieve the same cure rate, but the scar is smaller, less expensive. But the exploration of the cause of the disease, diagnosis and standardized treatment is still fraught with problems. [Conclusion]Developing by three generations, Gu ’s surgery department provides a more complete mentality and pragmatic value in treating plasma cell mastitis.

The robust nuclear-cytoplasmic transport is vital for eukaryotes'life cycle.Not only proteins and RNAs are transferred to their destination by this system, the important cellular activities such as mitosis are also regulated by the transport pathways via adjusting the local concentrations of some critical cargoes.tRNA is one of the most important biomacromolecules in the cell, synthesized in nucleus, and taking part in protein synthesis in cytoplasm.It is a long-held belief that tRNA functions only as a key player in protein synthesis, and tRNA nuclear-cytoplasmic transport is a unidirectional movement from nucleus to cytoplasm.However, the recent discoveries are overturning the traditional opinions.Nuclear-born tRNA can be exported out of nucleus, while cytoplasmic-residing tRNA can also be retrogradely transport into nucleus.The new concept tRNA nuclear-cytoplasmic dynamics was coined in 2008 to describe the tRNA communication between nucleus and cytoplasm, which was found able to regulate protein synthesis and cell cycle in S.cerevisiae.The latest results in this field are going to change the landscape of eukaryotic tRNA biology.
