Diagnostic methods play important role in theoretical system of Inner Canon of Huangdi.There are 74 articles about diagnostic methods,which contains near 50 kinds of TCM diagnostic methods referred to pulse diagnosis,colour inspection and so on.This paper analyze the connotation and extension of the term "diagnostic method",establish a theoretical framework of dynamic whole concept,bi-directional discrimination,characteristics of triple pathogens and four kinds of methods.The diagnostic model of"shape-spirit-transporting qi"and the modern language"nature-biology-psychology-society" four-dimensional diagnostic method are constructed.

Objective To monitor the release of amino acids of the whole retina during and after experimental glaucoma by increasing the intraocular pressure (IOP). Methods Experimental glaucoma was induced in one of the two eyes of rabbits by increasing IOP at 120 mm Hg for 45 min under infusion of saline in anterior chamber;then the pressure was released and the needle inserted into the anterior chamber was removed,this state was maintained for another 45 min.Every 15 min during the experiment 5 rabbits were killed and experimental eyes were enucleated.Aliquots (20 ?l) of the retinal extracts (see below) were mixed with ophthaldialdehyde reagent and analysed for amino acid content by the HPLC method of Wangwei, using a 150 mm?4.6 mm,5 ?m C18 column. Results A large increase in the release of glutamate,but not of the other three amino acids monitored,occurred during initial experimental ocular hypertension.It reached peak value of (111.73?17.46) 10 -5 mmol/g at 15 min of hypertension.15 min after release of intraocular pressure,again,immediately large and specific increase in the concentration of glutamate was reached to (102.96?51.91) 10 -5 mmol/g.In eyes subjected to paracentesis of anterior chamber,no difference was found between experimental eyes and controls. Conclusion These results suggest that glutamate is triggered by increasing the IOP,and it releases not only during the period of experimental ocular hypertension,but also afterwards.

Objective To observe the effect of different doses of butorphanol and sufentanil repeatedly epidural injected on the neurobehavior function in bone cancer model rats.Methods A PE-530 catheter was inserted into the epidural space of all male Sprague-Dawley rats(not mated,weighting 150-180 g) at L1-2 level.Three days after operation,64 rats without any motor dysfunction were randomly divided into eight groups (n=8):sham operated group (group C),normal saline with bone cancer pain group (group N),butorphanol groups(group B 1,B2,B3)and sufentanil groups (group S1,S2,S3).Bone cancer pain model was constructed in group N,B and S when rats in group C were sham operated.Rats in group C and N were epidurally injected NS 30μl each,and rats in group B1,B2 and B3 were respectively epidurally injected butorphanol 25,50,100 μg (all diluted to 30 μl with NS),when rats in group S1,S2 and S3 were respectively cpidurally injected sufentanil 1,2,4 μg (all diluted to 30 μl with NS) on time per day for 10-14 days after modeling.The neurobehavior paw withdrawal threshold (MWT) of the left hind claw was recorded to observe the changes in pain behavior.The neurobehavior function of rats were recorded by BBB (BASSO,BEATTIE and BRESNAHAN) score and the inclined plane test.Results Compared with group C((67.65±9.29) g),the MWT of the model groups obviously decreased before the first time of injection (N (15.23± 2.46) g,B 1 (16.14±2.28) g,B2(15.42±3.22) g,B3(14.35±2.32) g,S1 (15.37±2.11)g,S2(15.22±2.93) g,S3(16.25± 2.36) g) (all P＜0.05)).Compared with group N((16.13±2.37) g),the MWT of group B2,B3 and S3 increased obviously after the first time of injection ((35.12±5.16) g,(35.63± 1.53) g and (34.24±5.93) g) (P＜ 0.05).At the first day of injection,there was no significant difference in the BBB scores and the inclined plane test between the model groups (P＞0.05).At 6 h after the forth injection the inclined plane test and the BBB scores of group B3 were obviously decreased compared with group N ((34.72 ± 4.56) ° and (10.64 ± 1.82) points to (43.15±4.67)° and (14.05±1.78) points (P＜0.05)).Conclusion The results provide evidence that repeatedly epidural injection of butorphanol 50 μg or 100 μg or sufentanil 4 μg can reduce the pain of the rats with bone cancer pain.But repeated epidural injection of butorphanol 100 μg can injure the neurological function.

Objective To investigate the differences of clinical efficacy and untoward reaction of different chemotherapy regi‐mens for patients with malignant glioma on different expression levels of O6‐methylguanine‐DNA‐methyltransferase(MGMT) ,in order to provide references for clinical treatment .Methods Totally 90 cases of patients with malignant glioma in our hospital from January 2011 to January 2013 were selected ,among them ,64 cases of MGMT negative expressing patients were divided into group A and group B with 32 cases in each group ,and 26 cases of MGMT positive expressing patients were enrolled into the group C . Group A was treated with combination of radiotherapy ,teniposide and nimustine ,group B was treated with radiotherapy‐temozolo‐mide combination regimen ,group C was treated with combination of radiotherapy ,teniposide and nimustine .The untoward reactions of the three groups were compared ,and the survival rate was observed after one year follow‐up .Results The hemoglobin ,leuko‐cyte ,granulocyte ,platelet ,bleeding ,alanine aminotransferase ,creatinine ,urea nitrogen ,peripheral neuritis ,untoward reactions a‐mong the three groups had no statistically significant differences (P>0 .05);the incidence rates of nausea and vomiting ,diarrhea , constipation among the three groups had statistically significant differences(P<0 .05) ,in which group C was significantly higher than that of group A and group B(P<0 .05) .Only one case in the group C was lost in the one year follow‐up .The median survival time was 10 months in group A and group B ,and was 7 months in group C .The median survival time in group C was significantly lower when compared with that in group A and group B(χ2 =7 .673 ,P=0 .006 ;χ2 =6 .395 ,P=0 .011) ,while there was no signifi‐cant difference of median survival time between group A and group B(χ2 =0 .063 .P=0 .802) .Conclusion The long‐term prognosis of patients with negative MGMT expression might be significantly worse than that of patients with negative MGMT expression in glioma .

Objective:To investigate the effects of electroacupuncture (EA) at Neiguan (PC 6) and Baihui (GV 20) by observing the changes of CCAAT/enhancer-binding protein(C/EBP) homologous protein (CHOP) and caspase-12 gene expressions in rats after cerebral ischemia-reperfusion injury (IRI), and explore whether the apoptosis pathway of endoplasmic reticulum stress (ERS) is involved in the protective mechanisms of EA.
Methods:Sixty rats were randomly assigned to five groups (12 in each group): a normal control group (group A), a sham-operation group (group B), an operation group (group C), an Edaravone group (group D) and an EA group (group E). The cerebral IRI rat model was induced by middle cerebral artery occlusion (MCAO) using intraluminal monofilament. 2,3,5-triphenyl tetrazolium chloride (TTC) staining was adopted in the measurement of cerebral infarction volume. Real-time polymerase chain reaction (RT-PCR) was used to determine the mRNA expressions of CHOP and caspase-12.
Results: Compared with group A and group B, the volume of cerebral infarction and mRNA expressions of CHOP and caspase-12 in group C, group D and group E were increased, with statistical significances (P<0.05 orP<0.01); compared with group C, the volume of cerebral infarction and mRNA expressions of CHOP and caspase-12 in group D and group E were decreased significantly (P<0.05 orP<0.01); there were no significant differences between group D and group E in comparing the above items (P>0.05).
Conclusion:EA at Neiguan (PC 6) and Baihui (GV 20) can effectively suppress the volume of cerebral infarction. Furthermore, the underlying mechanism of EA at Neiguan (PC 6) and Baihui (GV 20) is possibly related to the down-regulation of CHOP and caspase-12 mRNA expressions, so as to decrease cell apoptosis.

Objective To approach the clinical value of ultrasound-guided percutaneous transhepatic cholangiographic drainage (PTCD) in the treatment of malignant obstructive jaundice.Methods Twenty-five patients with malignant obstructive jaundice were treated with uhrasound-guided PTCD,and the therapeutic effect and complications were observed.Results All the patients were successfully punctured,and the successful rate of single puncture was 92.00% (23/25) .Jaundice of all the patients decreased 3 to 6 days after PTCD.The serum total bilirubin and the inner diameter of intrahepatic ducts decreased after PTCD.The complications included bile exudation and slight bloody bile (either 1 patient) .Conclusion Ultrasound-guided PTCD is a simple,safe and effective way to reduce jaundice,and can be regarded as the first choice in the treatment of malignant obstructive iaundice.

Objective To observe the effect of epidural injection with different dose of butorphanol on the rats' neurological function.Methods A PE-530 catheter was inserted into the epidural space of all the SpragueDawley rats (male, weighting 180 ～210 g) at L1-2 level.After three days, a total of 32 rats without any motor dysfunction were randomly divided into 4 groups as follows saline(NS) group (group C, n= 8 )and butorphanol injection (B) group( B1∶ n=8;B2∶ n=8;B3∶ n=8).Rats in group C were epidurally injected NS 30 μl each ,and rats in group B1, B2 and B3 were respectively epidurally injected Butorphanol 60 μg/30μl, 120 μg/30 μl,240 μg/30 μl (all diluted with NS) ,and 1 time per day for5 days.The neurological function of rats was recorded before injection (T0) and 6h after injection on day 1 ～4(T1 ～T 4) and 6h,24h and 72h after injection on day 5 (T5 ～T7) by BBB (BASSO,BEATTIE and BRESNAHAN ) Score and the inclined plane test .Results Compared with group C ,the BBB score and the inclined plane test of group B1 showed no significant difference throughout the experimental period(P＞ 0.05 ).There was also no significant difference at T0 ～ T3 of group B2 and group B3 compared with group C (P ＞ 0.05 ), while at T4, the BBB score ( ( 18.50 ± 2.00 ) points, ( 16.38 ± 2.33 ) points) and the inclined plane test( (58.75 ± 5.17 )°, (59.38 ± 3.20) ° ) of the two groups were both obviously decreased when compared with group C( (21.00 ±0.00) points, (65.00 ±3.78)°, P＜0.05) ,and the same significant differences appeared at T5,T6 and T7 (P ＜ 0.05 ).Conclusion Repeated epidural injection of butorphanol 60 μg have no effect on neurological function of rats,while repeated epidural injection of butorphanol 120 μg and 240 μg could impaire the neurological function.
