Objective To determine oleanolic acid(OA)and ursolic acid(UA)from Fructus Ligustri Lucidi in diffrernt habitat and various growing stages.Method We picked the fruits of Fructus Ligustri Lucidi in Otober in five cities of Shanxi,and in August,September,October,November and December in Xi'an.Removed impurities and storaged the fruits under room temperature.By HPLC with Waters 600 as its chromatographic system,and Lichrospher C_(18)(4.6mmx250mm,5?m) column was applied with CH_3CN-CH_3OH-H_2O-H_3PO_4-(C_2H_5)_3N(50:30:20:0.02:0.04)as its mobile phase,the flow rate was 1 mL/min.The standard working curve was made to determine the contents of OA and UA at different habitat and different time spot from samples.Result The contents of OA and UA were highest in Ankang city.During prolonging growing stages,the highest contents of OA and UA were October and August,respectively.They both reduced to the lowest point in December.Conclusion The contents of OA and UA changed in different habitat and diffrernt growing stages of Fructus Ligustri Lucidi. It was suggested that we should mainly base on the highest contents to select the harvest time according to our demands.

Comrade LU Zhi-jun, a famous surgeon and acupuncture expert, was a leading cadre in health field with outstanding achievements, and a leader of western medicine doctors learning traditional Chinese medicine in the Chinese Communist Party, and also he was a main establisher of The China Academy of Chinese Medical Sciences and a founder of TCM scientific researches and integrated Chinese and western medicine in new China. The present paper reviews the course of LU Zhi-jun in learning and applying acupuncture and moxibustion therapy and a part of works carried out in faithfully implementing our party's policies for uniting Chinese and Western medicine, and in development of TCM including acupuncture and moxibustion in past tens years.

Objective To evaluate the clinical effects of different doses of brachical plexus anesthesia in the emergency suture of hand trauma in preschool children .Methods Forty preschool children with hand trauma were choosen ,who were undergoing e‐mergency suture by general anesthesia combined with brachical plexus anesthesia .They were divided into group A(1 mg/kg ,n=20) and group B(2 mg/kg ,n=20) ,body movement during skin incision ,local injection with lidocaine ,propofol dose ,surgical time and wake up time were compared .Results There was no significant differences between the two groups in surgical time(P>0 .05) ,the cases of body movement during skin incision and local injection with lidocaine were 8 children ,which was higher than 2 children in group B(all P<0 .01) ,ropivacaine dose(14 .5 ± 5 .5)mg in group A were lower than group B (31 .6 ± 7 .2)mg(P<0 .01) ,propofol dose in group A(75 .6 ± 15 .2)mg were higher than group B(32 .7 ± 8 .6)mg(P<0 .01) ,wake up time in group A(11 .2 ± 3 .3)min were longer than group B(5 .9 ± 2 .3)min (P< 0 .01) .Conclusion The clinical effect of ropivacaine 2 mg/kg was superior than 1 mg/kg in brachical plexus anesthesia .

MicroRNA (miRNA) is a family of endogenous single-stranded RNA about 22 nucleotides in length. Through targeting 3' UTR of message RNA (mRNA), they play important roles in post-transcriptional regulatory functions. For further research of miRNA function, the identification of more miRNA positive targets is needed urgently. Aiming at the high-dimensional small sample data sets in miRNA target prediction, an algorithm of eliminating redundant features is proposed based on v-SVM in this paper, and classification and features selection are also fused. The algorithm of eliminating redundant features optimizes the combination of features, and then constructs the best features combination which can represent miRNA and targets interaction model. The prior parameter v (0 < u < or = 1) controls the compression proportion of data set and selects more distinguishing support vectors. Finally, the classifier model of miRNA target prediction is built. The unbiased assessment of the classifier is achieved with a completely independent test dataset. Experiment results indicated that in both classification recognition and generalization performance of miRNA targets predicition, this model was superior to the present machine learning algorithms such as miTarget, NBmiRTar and TargetMiner, etc.

Diabetes is a chronic metabolic disease characterized by changes in the dynamic balance of blood glucose levels. Subcutaneous injection of insulin is a first-line treatment for diabetes. However, patient compliance is poor due to pain, discomfort, and local infection. Oral administration is convenient and safe, but the existing oral insulin preparations still need to be optimized due to gastrointestinal instability and poor bioavailability. The rapid development of nanopreparation technology provides a solid foundation for improving the bioavailability of oral insulin preparations and achieving the effective oral delivery of insulin. This paper reviews the research progress in insulin nanoparticles with high oral bioavailability in recent years.

Dryness is the inherent performance in traditional Chinese medicine. Dryness with a specific efficacy and side effect can be reduced suitably by processing and compatibility in the clinical application. Nowadays domestic scholars have developed research of dryness in traditional Chinese medicine. However, it remains problems such as evaluation index of dryness not clear. This paper takes medical literature mining technology to analyze the historical origin and features of dryness theory. Combing the modern literatures to explicate the dryness' research status and existing problems. Putting forward the traditional Chinese medicine and research should adopt multidisciplinary knowledge and study the system of comprehensive evaluation. Dryness is expected to further application in traditional Chinese medicine clinical research.

Objective To evaluate the effectiveness of occlusive wrapping with plastic film in the delivery room to prevent heat loss and reduce the occurrence of hypothermia on admission to the Neonatal Intensive Care Unit (NICU) in very low birth weight infants.Methods A total of 209 very low birth weight infants (birth weight＜1 500 g and gestational age＜33 weeks),born in the Second Hospital of Wenzhou Medical University (Yuying Children's Hospital) and admitted to the NICU immediately after birth from June 1,2009 to December 1,2010,were randomized to the wrap group or non-wrap group.Infants randomized to the wrap group were dried and then wrapped with polyethylene film up to their necks immediately after delivery.They were then covered with warmed blankets and transported to the NICU by the neonatal team.The non-wrap group received routine care in the delivery room following the guidelines of the Neonatal Resuscitation Program.The t test and Chi-square test were used for statistical analysis.Results The mean rectal temperature on admission to the NICU was significantly higher in infants of wrap group compared with those of non-wrap group [(36.1 ± 0.8) ℃ vs (35.5 ± 1.0) ℃,t=4.707,P＜0.01],and the incidence of hypothermia was 41.0％ (43/105) in the wrap group which was lower than that in the non-wrap group (66.3％,69/104) (x2=13.547,P＜0.01).In infants ＜29 weeks of gestation,the mean rectal temperature on admission to the NICU was higher in the wrap group than in the non-wrap group [(36.1 ± 0.8) ℃ vs (35.4 ± 1.1) ℃,t=3.051,P＜0.01].In infants ≥ 29 weeks of gestation,the mean rectal temperature on admission to the NICU was higher in the wrap group than in the non wrap group [(36.0±0.9) ℃ vs (35.5±0.9) ℃,t=3.698,P＜0.01].The arterial blood gas base excess in the wrap group and non-wrap group was-(2.9±2.7) mmol/L and-(5.0±4.2) mmol/L,respectively (t=4.473,P＜0.01).The rate of endotracheal intubation was 20.0％ (21/105) in the wrap group and 27.9％ (29/104) in the non-wrap group,(x2=1.785,P=0.182).The duration of hospitalization was (49.2± 10.7) d in the wrap group and (45.8±9.1) d in the non-wrap group,and the difference was not statistically significant (t=1.152,P=0.251).Conclusions Wrapping very low birth weight infants with plastic film in the delivery room can reduce the occurrence of hypothermia.
