Recently traditional Chinese medicine (TCM)-induced liver injury has been an unresolved critical issue which impacts TCM clinical safety. The premise and key step to reduce or avoid drug-induced liver injury (DILI) is to identify the drug source of liver injury in early stage. Then the timely withdrawal of drug and treatment can be done. However, the current diagnosis of DILI is primarily governed by exclusive method relying on administering history supplied by patients and experience judgment from doctors, which lacks objective and reliable diagnostic indices. It is obvious that diagnosis of TCM-induced liver injury is especially difficult due to the complicated composition of TCM medication, as well the frequent combination of Chinese and Western drugs in clinic. In this paper, we proposed construction of research pattern and method for objective identification of TCM-related DILI based on translational toxicology, which utilizes clinical specimen to find specific biomarkers and characteristic blood-entering constituents, as well the clinical biochemistry and liver biopsy. With integration of diagnosis marker database, bibliographic database, medical record database and clinical specimen database, an integrative diagnosis database for TCM-related DILI can be established, which would make a transformation of clinical identification pattern for TCM-induced liver injury from subjective and exclusive to objective and index-supporting mode. This would be helpful to improve rational uses of TCM and promote sustainable development of TCM industry.

Objective To investigate the age-associated changes of ultrastructure,mRNA and protein expressions of H+-K+-ATPase in elderly gastric parietal cell. Methods Fifty patients with relative normal stomach without gastroduodenal diseases were enrolled,including younger group (aged 20-59 years,n=19) and elderly group (aged≥60 years,n=31).Furthermore,the elderly group was divided into 3 subgroups:60-69 years old (n =11 ),70-79 years old (n=10 ),above 80 years old (n =10).The ultrastructure of gastric parietal cell was observed under electron microscope.The expression of H+-K+-ATPase α subunit mRNA and H+-K+-ATPase β subunit protein were assessed by quantitative real-time PCR and Western-blot,respectively.The ageing-associated changes of all these data were respectively compared. Results No significant difference was showed in the morphology of gastric parietal cell and acid-secretion-associated organelles among all the groups.The average ratio Am to Ac (Am means the area of mitochondria,Ac means the area of cytoplasm) of gastric parietal cell and the average At to Ac ratio (At means the area of secretory canaliculi and tubulovesicular system )between younger group and elderly group had no significant difference[(48.4±7.5) ％ vs.(50.6±7.6) ％,t=-0.775,P=0.444; (13.8±4.1) ％ vs.(12.2±4.7) ％,t=0.984,P=0.332].Meanwhile,there were no distinctions in the expression of H+-K+ -ATPase α subunit mRNA and H+-K+-ATPase protein among all elderly subgroups(F=1.522,2.32,P=0.24,0.114).However,the mRNA expression of H+-K+-ATPase a subunit was higher in the elderly group than in the younger group(t=-3.682,P=0.001).Furthermore,the expression of H+ -K+ -ATPase protein in the elderly group was increased as compared with younger group(t=-3.389,P=0.004). Conclusions Acidsecretion-associated organelles of human gastric parietal cell have no degeneration and the expression of H + -K+-ATPase is in trend of increase with aging,indicating that healthy elderly people have the basis of ultrastructure and molecular biology to maintain well function of acid secretion.

BACKGROUND: Changes in extracellular of chondrocyte can reflect influence of external force on temporomandibular joint and adaptability of body to external force. OBJECTIVE: To study the effect of cyclic tensile stress on main extracellular matrix of condylar chondrocyte.METHODS: The cyclic tensile stress was exposed to the third passage condylar chondrocyte for 0, 1, 6, 12 and 24 hours, respectively, using a Flexcell Strain Unit-5000T system (10% surface elongation, 6 cycles/min). After mechanical loading, total RNA was extracted from the cells harvested from Six-well BioFlex flexible cell Petri Dish, reverse transcribed, and reverse trabscription-PCR was performed to quantify mRNA levels for type Ⅱ collagen and aggrecan.RESULTS AND CONCLUSION: Compared with the control group (0 hour group), both type Ⅱ collagen and aggrecan mRNA expression was significantly increased after loading for 6 hours (P < 0.05), but began to decrease since 12 hours, and significantly decreased at 24 hours (P < 0.05). Results showed that cyclical tensile stress stimuli can affect the synthesis of main extracellular matrix of condylar cartilage, i.e. the synthesis was gradually enhanced with prolonged stimulation duration, but significantly inhibited in response to further stress stimuli.

ObjectiveTo investigate the haemostatic effect of combining pulsed therapeutic ultrasound (TUS) and microbubble (MB) on splenic trauma.MethodsForteen healthy dogs were divided into 3 groups.Six animals were treated by microbubble-enhanced therapeutic ultrasound (MEUS),the other eight animals were treated with TUS only ( n =4) and the MB only ( n =4) served aS the controls.The spleens of all animals were surgically exposed and a 20 mm long,5 mm deep incision was created on the spleens using scalpel.Human prothrombin complex (HPC) was slowly injected prior to the treatment.During the procedure,the initial bleeding rate and the bleeding rate after the treatment were calculated using gauze weighing.Contrast enhanced ultrasound (CEUS) was performed to assess the blocking effects of splenic circulation.The targeted spleens were harvested for pathological examination.ResultsThere were no differences in initial bleeding rate before treatment.After treatment,in the MEUS group oozed blood was found and the bleeding rate were lower than that of the TUS and the MB groups ( P ＜0.05).A nonenhanced or perfusion defect region was formed within the treated area.The histological results showed splenic sinus hyperemia,platelet aggregation and intravascular thrombosis.Conclusions Microbubbles enhanced pulsed therapeutic ultrasound can arrest the regional blood circulation of spleen by disrupting the microvasculature and this can be used in splenic heamostasis for treating spleen trauma.

Objective:To describe a method based on analysis of the histogram of intensity values pro-duced from the magnetic resonance imaging (MRI)for quantifying the degree of fatty infiltration. Methods:The study included 25 patients with dystrophinopathy.All the subjects underwent muscle MRI test at thigh level.The histogram Mvalues of 250 muscles adjusted for subcutaneous fat,representing the degree of fatty infiltration,were compared with the expert visual reading using the modified Mercuri scale.Results:There was a significant positive correlation between the histogram Mvalues and the scores of visual reading (r =0.854,P <0.001).The distinct pattern of muscle involvement detected in the pa-tients with dystrophinopathy in our study of histogram M values was similar to that of visual reading and results in literature.The histogram M values had stronger correlations with the clinical data than the scores of visual reading as follows:the correlations with age (r =0.730,P <0.001 )and (r =0.753, P <0.001);with strength of knee extensor (r =-0.468,P =0.024)and (r =-0.460,P =0.027) respectively.Meanwhile,the histogram Mvalues analysis had better repeatability than visual reading with the interclass correlation coefficient was 0.998 (95% CI:0.997 -0.998,P <0.001)and 0.958 (95%CI:0.946 -0.967,P <0.001)respectively.Conclusion:Histogram Mvalues analysis of MRI with the advantages of repeatability and objectivity can be used to evaluate the degree of muscle fatty infiltration.

OBJECTIVETo observe the clinical effect of chronic fatigue syndrome (CFS) treated with moxibustion at Gaohuang (BL 43).

METHODSWith stratified block randomization, 72 patients accorded with inclusive criteria were divided into a moxibustion at Gaohuang (BL 43) group (moxibustion group) and an acupuncture group, 36 cases in each one. In the moxibustion group, Gaohuang (BL 43) was treated with big moxa cones as the main acupoint, 10 cones a time; Qihai (CV 6) and Zusanli (ST 36) were added with big moxa cones, 7 cones a time. In the acupuncture group, acupoints were the same as those in the moxibustion group, and twirling reinforcing method was used after qi arriving, 60 times one minute and 360° with range. In the two groups, 10-day treatment was made into one course and there were two days between courses. The treatment was given once a day for 3 courses. Changes of fatigue assessment index (FAI) before and after treatment and clinical effects were observed.

RESULTSThe total effective rate was 88.9% (32/36) in the moxibustion group, which was better than 72.2% (26/36) in the acupuncture group apparently (P < 0.05). After treatment in the two groups, FAI scores were obviously declined compared with those before treatment (both P < 0.01) and FAI score in the moxibustion group was apparently lower than that in the acupuncture group (P < 0.05).

CONCLUSIONMoxibustion at Gaohuang (BL 43) can improve the FAI score of patients with CFS and the clinical efficacy is definite.
