1.Nutrition Status of Premature Neonates in Early Postnatal Stage in Neonatal Intensive Care Unit
Journal of Applied Clinical Pediatrics 2006;0(14):-
Objective To study the nutrition status of premature infants in the early postnatal stage.Methods According to the physical development standard,the premature neonates for treatment in our NICU from Jun.2007 to Jun.2009 were enrolled and divided into normal growth group and extrauterine growth restriction(EUGR) group.The nutrition status of these premature neonates were evaluated respectively.SPSS 13.0 software was used to analyze the data.Results Compared with EUGR group,the durations of regaining birth weight were shorter in normal growth group(t=-13.83,P0.05).Conclusions Premature neonates are prone to encounter extrauterine growth retardation.Extrauterine growth retardation had great impact on premature neonates.Premature neonates should be strengthened with nutrition supplement in order to reduce the incidence of extrauterine growth retardation.
2.Effect and mechanism of ligustrazine on the airway smooth muscle of isolated guinea pigs
International Journal of Pediatrics 2014;(5):544-547
Objective To observe the effect and mechanism of Ligustrazine ( LIG ) on the Airway smooth muscle( ASM) of isolated guinea pigs. Methods The normal guinea pig bronchus were made into tra-chea spiral,and randomly divided into LIG group, LIG+Propranolol group, LIG+Atropine, LIG+Nifedipine group,LIG+Glibenclamide group and the control group. The effect of different concentrations of LIG on the ASM was respectively observed in the resting tension and the high tension caused by histamine,and the ASM re-laxation rate were compared between each groups. Results (1)It had diastolic function for LIG on the isolated guinea pigs ASM in the resting tension and the high tension caused by histamine. (2)In the resting tension,com-pared with the group LIG,the diastolic function was antagonism by the concentration of LIG 10-7 ~10-6. 5 mol/L in the group LIG+Propranolo (P<0. 05). The diastolic function had no significant difference by the concentra-tion of LIG 10 -7.5 ~10 -3 mol/L in the group LIG+atropine and LIG+Glibenclamide(P>0. 05). The diastolic function was improved remarkably by the concentration of LIG 10 -6 ~10 -4 mol/L,in the group LIG+Nifedip-ine (P<0. 05). (3)In the high tension caused by histamine,compared with the group LIG,the diastolic function was antagonism obviously by the concentration of LIG 10 -6. 5 ~ 10 -5 mol/L in group LIG+Propranolol ( P<0. 05);The diastolic function had no significant difference by the concentration of LIG 10 -8 ~10 -3 mol/L in group LIG+atropine,and LIG+Glibenclamide (P>0. 05);The diastolic function was improved remarkably by the concentration of LIG 10 -6.5 ~10 -5 mol/L in group LIG+Nifedipine (P<0. 05). Conclusion It has dias-tolic function for LIG on the isolated guinea pigs ASM in the resting tension and the high tension caused by his-tamine. The effect and mechanism may be related with the competitive exciting beta 2 receptor and the inhibitor of Ca2+ internal flow. It provides a theoretical basis for the clinical application of LIG in treating asthma.

China Pharmacy 2005;0(19):-
OBJECTIVE:To provide reference for standardization of drug package.METHODS:5 dose-related items stated in a total of 426 package inserts of chemical drugs collected from the drug storeroom in our hospital were investigated and analyzed.RESULTS:Only 32.39% of the package inserts were with complete labeling.The labeling rate for special group was low and only 40% labeled the maximal dose.Less than 2% of child dose stated the doses according to body surface area,and the problem of over-dose was common.Only 27.46% had the item of "under supervision of a physician".CONCLUSION:It is necessary to strengthen supervision on drug package inserts and improve cognition on the importance of drug package inserts.
4.Key issues in the diagnosis of osteoporosis
Chinese Journal of Endocrinology and Metabolism 2011;27(2):101-105
Several key issues in the diagnosis of osteoporosis were discussed. The definition of osteoporosis and some concepts in bone fracture risk evaluation were explained, so as the methods to avoid the common misunderstandings in clinical practice. Finally, the parameters used in determination of bone metabolism and bone mass were listed, and their application and limitation were analyzed. It may help the clinicians to make correct choice of these parameters.
5.Progress in the research on 21-gene Oncotype Dx in breast cancer prognosis
China Oncology 2009;19(12):953-958
Currently the most effective treatment strategy for breast cancer is standardized multi-discipline comprehensive treatment. However, there are no effective models that can accurately predict prognosis, so that no guidance of individualized treatment has yet been set up, resulting in a proportion of patients with low risk who received chemotherapy with little benefit. With the development of genomics, several gene sets have been demonstrated to be helpful in predicting of breast cancer prognosis and grading the patients' benefit from chemotherapy, thus avoid overtreatment. 21-gene Oncotype Dx was reported as one of them and has been demonstrated to be effective and accurate in various clinical studies. This paper summarizes researches on 21-gene Oncotype Dx in breast cancer.

8.Early diagnostic value of serum amyloid A combined with C-reactive protein in diagnosis of influenza A in children
The Journal of Practical Medicine 2017;33(14):2368-2370
Objective To evaluate the clinical value of serum amyloid protein(SAA),C-reactive protein (CPR)and SAA/CRP ratio in early diagnosis of influenza A in children. Method SAA,CRP,SAA/CRP ratio and serum white blood cell(WBC)count were measured in 417 children. One hundred and thirty-nine children were diagnosed with Influenza A and were enrolled in the influenza A group ,and the other 278 healthy children were enrolled in the control group from April 2016 to June 2016. The values of the screened biomarkers for diagno-sis of influenza A were assessed by ROC curve analysis. Results Levels of SAA,CRP and SAA/CRP ratio in the influenza A group were significantly higher than those in the control group(P<0.001,respectively). The areas un-der the ROC curve of SAA and SAA/CRP ratio for the diagnosis of influenza A were higher than 0.7(P<0.001). The optimal cut-off values of SAA and SAA/CRP ratio for the diagnosis of Influenza A were 10.500 mg/L and 6.165,respectively. The corresponding sensitivities of the optimal cut-off values for the diagnosis of influenza A were 85.5% and 55.4%,respectively,and the corresponding specificities were 96.8% and 91.4%,respectively. Conclusion Measurement of SAA and SAA/CRP ratio are valuable biomarkers for clinical in early diagnosis of in-fluenza A and SAA has a better diagnostic performance than CRP.

Journal of Endocrine Surgery 2014;(4):282-285
Objective To discuss the pathological morphological features of the macrofollicular variant of papillary thyroid carcinoma ( MFPTC ) .Methods Clinical data of 2 cases of MFPTC were reviewed .The his-topathological and immunohistochemical features were analyzed .Relevant literatures were reviewed .Results The histological characters of MFPTC mainly included its multiple macrofolliculus , plenty of colloid and atypical nuclear morphology.Immunohistochemistry stain showed cytokeratin-19, Galectin-3 and HBME-1 expressed simultaneously. Conclusions MFPTC is a thyroid papillary carcinoma with unique histological characters .It should be differen-tially diagnosed from some benign lesions such as nodular goiter and follicular adenoma .Immunohistochemical stain of cytokeratin-19, Galection-3 and HBME-1 may be very helpful in the diagnosis and differential diagnosis .
10.Study on the Principal Component of Out of Pocket Expenditure Ratio
Chinese Health Economics 2017;36(5):40-44
Objective:To compare and analyze the changes and the influencing factors of out of pocket(OOP) expenditure before and after the new medical reform.Methods:2000-2015 time series data was used to compare the changes of OOP in different years.The cross-section data was applied to compare the OOP of China and other countries.The principle component analysis method was used to research the contribution rates of different factors for the OOP ratio changes.Result:According to the vertical comparison,it found that the OPP ratio showed steady decreasing trend.The horizontal comparison found that there were great gap for OOP ratios of China and other countries.The per capita GDP,under five mortality and proportion over 65 years were significant factors for OOP.Conclusion:The OOP ratio still needed to be devreased,which needed to promote the economic growth,implement medical insurance system,improve the public health input and decrease the health economic burden for residents.
