Traditional Chinese medicine (TCM) emphasizes treatment based on syndrome differentiation, which em-bodies the concept of individualized diagnosis and dynamic treatment on a holistic view. RCT was frequently used in TCM clinical study. However, it cannot reflect the concept of treatment based on syndrome differentiation. The use of adaptive treatment strategies (ATS) in clinical research can adjust therapy in patients according to the change of disease, so it can reflect personalized medicine and dynamic treatment. From this perspective, the process of treat-ment based on syndrome differentiation was a process of adaptive treatment decision. So the method for developing ATS can effectively evaluate the efficacy of different treatment strategies in TCM clinical study. ATS had been used in some clinical studies from published literatures abroad. However, the use of ATS in domestic clinical research was seldom been reported. This paper gave an outline of the concept of ATS. In addition, this paper focused on three methods which can take the delayed effects of current treatment action into consideration and can compare the over-all effect of different ATS. It was hoped to lay foundation for future scientific research of TCM in the implementation of SMART and provide a new idea.

Traditional Chinese medicine (TCM) emphasizes treatment based on syndrome differentiation, which is the core technology that can embody the characteristics and advantages of TCM diagnosis and treatment. This is based on holistic view to illustrate individual diagnosis and treatment and dynamic treatment. However, RCT, which is frequently used in TCM clinical studies, can not reflect the concept of treatment based on syndrome differentiation. The use of adaptive treatment strategies in clinical researches can adjust therapy in patients according to the changes of diseases, so it can reflect individual diagnosis and treatment and dynamic treatment. From this perspective, the process of treatment based on syndrome differentiation is a process of decision-making of adaptive treatment. So the method for developing adaptive treatment strategies can effectively evaluate the efficacy of different treatment strategies in TCM clinical studies. Adaptive treatment strategies have been used in some clinical studies from some published foreign literatures. However, the use of adaptive treatment strategies in domestic clinical researches is seldom reported. This article discussed the concept of adaptive treatment strategies and their important components in detail. In addition, it presented three methods which can take the delayed effects of the current treatment action into consideration and can compare the overall effect of different adaptive treatment strategies, with a purpose to lay some foundation for future TCM researches in the development of optimal clinical pathway and provide new ideas and methods for researches.

Objective To understand the global economic burden of diseases due to needle stick injuries(NSIs), obtain relevant evidence,and prompt the relevant departments to pay attention to the precaution of NSIs.Methods Literatures about NSIs published from 1990 to May 2016 were searched from PubMed,ScienceDirect,EBSCO-host,Cochrane,CNKI,and Wanfang database.According to world bank inflation rate and currency rate in 2015, cost of needle stick injury in each study was adjusted to US dollars in December 2015,merge comparison analysis was performed.Results A total of 7 literatures were included,3 American studies and 4 studies from Sweden,Ko-rea,Belgium,and Taiwan Region of China respectively.Studies in mainland China only focused on the incidence of NSIs,studies about cost were not found.Two studies did not identify studied population,the remaining 5 studies were about all staff in the medical institutions.Cost analysis method:Of 7 literatures,3 were first-hand data analy-sis,4 were derived from the model.Scope of cost research:4 studies estimated the direct cost,2 calculated direct and indirect cost respectively,only 1 study estimated the summation of direct and indirect cost.The total cost per inj ury (direct cost + indirect cost)was $747-$2173,direct and indirect cost were $167-$617 and $322-$455 respectively.Conclusion Global economic burden of NSIs is heavy and still undervalued;NSIs occur frequently in China,but attention is inadequate,research on economic burden is lacking,relevant departments should pay atten-tion to the prevention and follow-up treatment process of NSIs.

Objective To study the effect of a polysaccharide from cuscuta chinensis lam (PCCL) on antisenility and its mechanism. Methods Sixty Kunming mice were randomized into 6 groups. The three PCCL groups were administrated with PCCL of 100, 200, 400 mg?kg -1?d -1 orally, the positive control group with vitamin E of 200 mg?kg -1?d -1, the model group and control group with the same volume of control solution only. At the same time, the model group, the positive group and the three PCCL groups were subcutaneously injected of 5% D-gal at the dose of 0.5 ml at the nape, and the control with the same volume of saline solution. Seven weeks later, the MDA, SOD activity, GSH-PX activity in the liver and kidney of mice and lipofuscin (LF) in mouse brain were detected with the methods of TBA, Nitrate, DTNB and Sohal, respectively. The data were analyzed with SPSS software and the data between groups were analyzed with one-factor variance analysis. Results Thymus index and spleen index dropped, LF rose in brain, malondialdehyde (MDA) content rose and the activities of superoxide dismutase (SOD) and glutathione peroxidase (GSH-PX) dropped in liver and kidney in senile mouse model. PCCL administration of 100, 200, 400 mg?kg -1?d -1 made thymus index and spleen index rising, LF dropping in brain, MDA content dropping,SOD and GSH-PX LF rising in liver and kidney of senile mouse model. Conclusion PCCL may postpone senility, which mechanism probably connected with rising immunity, eliminating oxygen free radicals and antilipoperoxidation.

Objective To study the activities of the alcoholic extract from Fructus Polygoni Orientalis (EFPO) against antioxidation. Methods The peroxidation in homogenate of rat heart, liver and kidney was induced by ?OH generation system Fe2++ascorbic acid. Malondialdehyde (MDA) was determined by TBA colorimetric method. Superoxide (O-2) from zymosan-stimulated neutrophils of rat was measured by NBT reduction method. H2O2-caused hemolysis of erythrocytes was measured by spectrometry. Results MDA in homogenate of heart, liver and kidney of rat that induced by ?OH generation system Fe2++ascorbic acid was inhibited by 6.3, 12.5, 25, 50, 100, 200 ?g/L EFPO; IC50 of EFPO to MDA in heart, liver and kidney was 31.8, 32.5 and 40.2 ?g/L respectively and its dose-effect relation was of negative relativity and the relative coefficient was -0.886, -0.874 and -0.918 (all P

Objective To investigate the clinical significance and coagulation function changes in newborn hemolytic disease. Method The newborn hemolytic disease ( 60 cases, hemolytic disease group ), non-hemolytic hyperbilirubinemia (60 cases, non-hemolytic hyperbilirubinemia group) and normal newborn (60 cases,control group) were selected as the study subjects, the prothrombin time (PT) and activated partial thromboplastin time (APTT) were measured, and the blood platelet count at the same time was detected. Results PT and APTT in hemolytic disease group were higher than those in non-hemolytic hyperbilirubinemia group[(28.79 ?.21) s vs. (18.98?.41) s and (58.52?.13) s vs. (47.26?.81) s], and they were apparently higher than those in control group [(13.81 ?1.83) s and (38.10 ?3.00) s], the difference had statistic significance (P<0.05). There was no statistic significance to detect the blood platelet count (P> 0.05). Conclusions The newborn hemolytic disease has the bleeding tendency, and the bleeding tendency has no relationship with the quantity of the blood platelet, but relates to the extension of PT and APTT. The more serious the case is, the more obvious the PT and APTT rise. PT and APTT can be as the detection index and evaluating effect of the newborn hemolytic disease coagulation function.

A method was developed for the determination of four sulfa antibiotics in groundwater, soil and excreta using solid phase micro extraction disks coupled with high performance liquid chromatography. The influence of eluent, different solid phase micro extraction membranes on the recovery of sulfa antibiotics in groundwater was investigated and it was found that when using the mixture of methyl alcohol and 1 . 0% formic acid as eluent, HLB ( divinyl benzene-N-vinyl pyrrolidone polymer ) as extraction membranes, an optimal enrichment effect was obtained. Different pretreatment methods for the 3 kinds of samples abovementioned were also examined. It was found that the signal response values obtained by using mixture of methyl alcohol and 1 . 0% formic acid as base solution of standard or sample solution was higher 8-10 times than that by using methyl alcohol only. Under the optimal conditions, good linear relationships were obtained in the sulfa antibiotics concentrations of 0 . 005-10 . 0 mg/L with the correlation coefficients>0 . 9999;The detection limits of sulfathiazole ( ST ) , sulfadiazine ( SM ) , sulfamethazine ( SM2 ) , sulfamethoxazole ( SMX ) were 1 . 08 , 3. 56, 4. 63 and 1. 84 ng/L(S/N=3), respectively. The enrichment factors for four sulfa antibiotics were 4000 times with solid phase micro extraction disks. The RSD of matrix spiked samples were 0. 1%-0. 4%(n=7). The proposed method was applied to the determination of the four sulfa antibiotics in groundwater, soil and excreta with spiked recoveries of the four sulfa antibiotics in the range of 69 . 80%-117 . 60%.

ObjectiveTo investigate the change of D-dimer in haemolytic disease of newborn and its clinical significance. MethodsSixty cases with haemolytic disease of newborn were divided into nonserious group(34 cases) and serious group(26 cases) by the level of bilirubin, 40 cases of normal neonatus (control group) were also selected. The levels of D-dimer and fibrinogen(FIB) were measured and compared.ResultsThe level of D-dimer in serious group and non-serious group[ (9.29 ± 11.34), (0.84 ± 0.77 ) mg/L]was higher than that in control group [ (0.45 ± 0.06) mg/L](P ＜ 0.01 or ＜ 0.05 ),the level of D-dimer in serious group was higher than that in non-serious group (P＜ 0.01 ). There was no significant difference in the level of FIB among the three groups (P ＞ 0.05). ConclusionsThere is hypercoagulability in the serious haemolytic disease of newborn. It is valuable to detect plasma D-dimer density for serious haemolytic disease of judgement and treatment.

Objective To estimate the bladder symptoms, and explore its impact on patients′ quality of life in type 2 diabetes mellitus. Methods Overactive bladder symptom score (OABSS) was used to evaluate patients′ bladder symptoms, and Medical Outcome Study 12-Item Short Form Health Survey Scale (SF-12), Overactive Bladder Questionnaire Short Form(OABq-SF)were conducted to test the effect of bladder symptoms on general and disease-specific quality of life. Results Among the four bladder symptoms, nocturia was the most prevalent symptom (46.7%,479/1025 ), followed by urinary frequency (14.9%,153/1025 ),urinary urgency (14.2%,146/1025 ), urge urinary incontinence (7.9%, 81/1025). Nocturia and urge urinary incontinence significantly increased symptom bother (nocturia B=0.337,P<0.01;urge urinary incontinence B=0.437,P<0.01) and decreased disease-specific quality of life (nocturia B=-0.364,P<0.01;urge urinary incontinence B=-0.346, P<0.01) in these patients. Meanwhile, urge urinary incontinence was negatively associated with general mental health (B=-0.255, P=0.011). Conclusions The prevalence of bladder symptoms in type 2 diabetes patients was high, and was found to be associated with patients′general and disease-specific quality of life. Health care providers should be aware of the high prevalence of bladder symptoms and its impact on QOL to facilitate early diagnosis and treatment of bladder symptoms during diabetic care.

Objective To investigate the surrounding and central dosimetric distribution difference of the same activity, same number of 125I seeds. Methods 3D treatment planning system (3D-TPS) was used to separately sketch out 7 cubes with side length of 2 cm, 2.5 cm, 3 cm, 3.5 cm, 4 cm, 4.5 cm and 5 cm;simulations of different tumor sizes were established, into which 125I seeds with activity of 0.5 mCi were respectively loaded. All seeds were distributed at the periphery of the tumor (peripheral group) with the prescribed dose of 145 Gy. The dose volume histogram (DVH) was printed and the 90% of target volume absorbed dose (D90), 90% of prescription dose coverage target volume percentage (V90), the maximum dose and mean dose were determined. Then the seeds in every cube were distributed into the center (central group) and the above parameters were calculated by using the same method. Results The mean D90 of the peripheral and central group was (147.29 ±0.58) Gy and (106.08 ±9.40) Gy respectively, the difference between the two groups was statistically significant (t=-4.292, P=0.005). The mean V90 of the peripheral and central group was (95.46±0.44)% and (79.07±4.19)% respectively, the difference between the two groups was statistically significant (t=-3.831, P=0.009). The mean maximum dose of the peripheral and central group was (1 224.65 ±12.7) Gy and (1 532.48 ±48.54) Gy respectively, the difference between the two groups was statistically significant (t=6.823, P=0.000). The mean value of average dose of the peripheral and central group was (192.14 ±2.89) Gy and (179.81 ±5.40) Gy respectively, the difference between the two groups was statistically significant (t=-2.847, P=0.029). Conclusion The dose distribution is directly influenced by the distribution pattern of the 125I seeds. When the number and activity of the 125I seeds are the same, the peripheral seeds implantation has a better dose distribution.
