The resource limitation, ineffective utilization and severe waste generated during processing restrict the sustainable development of the Chinese herbal medicine industry. The main reasons lie in insufficient utilization of medicinal components as well as few and outdated technologies. Integration and optimization of serial technologies including pretreatment, extraction, conversion and waste treatment are the keys to solve these issues. In this article, the updated research progress and technology development of biorefinery engineering for herbal medicines are reviewed. Guided by multi-products oriental fractionation refining, Chinese herbal medicine refinery technical system is constructed relied on advanced refinery technology platforms.

Inspect the anchorage molars with band and the anchorage molars with buccal tube with dental plaque index and gum in- dex and then statistically process the objective data obtained.The results show that both wearing band and wearing buccal tube lead to dental plaque.The influence is less worse on the the anchorage molars with buccal tube.

Objective To evaluate the reason why patients can not continue or complete the periodontal treatment stage of maintenance.Methods To communicate well with 136 patients who were diagnosed periodontitis to know why they can not continue or complete the periodontal treatment stage of maintenance.Results How deep the patients know about the importance of the stage of maintenance is the main reason to stop them continue or complete the stage of maintenance therapy.Conclusions To communicate well with periodontal patients can make them know much about periodontitis and they can complete periodontal treatment plan better.

Objective To evaluate the result of appliance of Periocline treating acute topical type periocornitis of wisdom tooth with clinical observation examination. Methods 127 cases that were clinical diagnosed acute topical type periocornitis of wisdom tooth was randomly assigned of two groups, treatment group with Periocline after rising. The contrast group with iodoglycerin after rinsing.Results The curative effect with Periocline was obviously better than that in the contrast group. The efficacy was significantly(P

Obiective To study the value of procalcitonin (PCT) and C-reaction protein (CRP)in the diagnosis of bacterial infection.Methods PCT and CRP in 2120 patients were retrospectively analyzed.Receiver operating characteristic (ROC) curve was used to compare the diagnostic capacity between two indices.Correlation between PCT and CRP was analyzed among 178 patients with bacterial infection.Results Areas under ROC curve (AUC) were 0.957 ±0.016 for PCT and 0.712 ± 0.04 for CRP.There was statistical significance of the AUC for PCT and CRP.The optimum cutoff value for PCT was 0.4 μg/L,which had a sensitivity of 90.0％ and a specificity of 90.9％.The optimum cutoff value for CRP was 2.27mg/L,which had a sensitivity of 72.0％ and a specificity of 57.3％.In the 2120 patients,there was the situation which PCT was normal (＜0.1 μg/L) when CRP was normal (＜0.8 mg/L).Conclusions In prediction of bacterial infection,CRP was not good,but PCT had high clinical value because of rapid detection,less interference and high specificity.In suspected bacterial infection patients,PCT was considered not to be detected temporarily if CRP was normal.In this way,there was the economic value which the patient's medical costs may be Controlled and medical resources be saved.Combined with its half-life,monitoring and analyzing the PCT change is valuable for efficacy determination and assessment of the patients'conditions.

Melatonin holds a wide range of biological effects, its multi-channel and multi-target impacts on reproductive sys-tem are the basis of pregnancy related rhythm, including conception, the duration of pregnancy and delivery.This paper describes the synthesis of melatonin, the characteristics of melatonin receptors distribution and melatonin′s biological property.It also illuminates the influence of melatonin rhythm on the above-mentioned courses, hoping to provide theory basis for clinical suggestions to modulate rhythm around pregnancy.

Objective To investigate the health status of university faculty.Methods The healthy physical examination results of teaching staff in Beijing University of Technology in 2012 were statistically analyzed.Results Among 4 191people,3 678 were examined abnormal.The prevalence rate was 87.97％.A total of 36 kinds of diseases were detected,and mainly in chronic diseases such as pharyngitis,fatty liver,hyperlipidemia,hypertension,breast hyperplasi a,diabetes or fasting glucose ≥7.00mmol/L and others.The prevalence rate in the male staff was significantly higher than that in female staff(all P ＜ 0.05).Condusion College teachers' health condition is not optimistic.Necessary preventive measures such as regularly medical examinations,strengthening health care and education should be taken and implemented.

The environmental pollution caused by organo tin attracted much concern,at the same time, the methodological study on determination of organo tin in environment made a desirable development, the chromatograph technique was used widely.A more detailed review on application of gas chromatograph and its coupled techniques in the environment organo tin compounds analysis was presented in this paper.

Objective:To explore the effect of group tutoring in the adaptation education for college freshmen.Method:All freshmen that attended Wenzhou medical college in 2008 are enrolled in group tutoring to help them better adapt to the new life in college,and the tutoring effect is appraised by a self-designed questionnaire.Result:The freshmen show a general progress and satisfaction after receiving group tutoring,and regard it quite necessary to conduct activities like group tutoring at the beginning of college life to help make freshmen better adaptive.Conclusion:Group tutoring is very effective in the adaptation education for college freshmen,and has a universal applicability for all college students.

We used domestic perfluorotributylamine to treat 21 eyes with giant retinal tears, including 5 rhegmatogenous retinal detachment with folded and fixed flap and 16 giant retinal tears resulting from retinotomy and retinectomy due to complicated retinal detachment. The success rate of retinal reattachment was over 95%, with no serious side effects. The activities and complications of perfluorotributylamine in the mangement of giant retinal tears were discussed.
