Chinese Journal of Clinical Psychology 1993;0(01):-
Objective: To develop the Chinese mood adjective check list (CMACL) and study the validation of this scale. Methods: The CMACL was filled by 1010 subjects aged 21.0 ? 7.4, 507 males and 464 females (39 lost gender information), which were randomly split into two samples after balancing the gender for exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). 232 middle school students divided into five groups according to their grades were engaged in the test-retest study at the first to fourth and sixth weeks. 34 volunteers finished the CMACL and self-rating depression scale (SDS) and 30 college students joined the validation study to test the correlation between the CMACL and state trait anxiety inventory. Results: A four-factor model was found by EFA and confirmed by CFA, which has the following dimensions: Fidget(F)?Happy and excited(HE), Pain and sad(PS),Angry and hate(AH). 30 items were also left in the CMACL after the modification(GFI=0.902,AGFI=0.883,NFI=0.884,TLI=0.931,CFI=0.937,RMSEA=0.046). Reliabilities of the four factors are higher than 0.80. Validation studies showed: (1) SDS total score is significantly positive-correlated with F (P

Chinese Journal of Clinical Psychology 1993;0(02):-
Objective: to develop the peptic ulcer (PU) symptoms self rating scale (PUSRS) and study the validation of this scale. Methods: The PUSRS was filled by 151 PU patients, 118 males and 30 females (3 lost gender information, aged 38.61?14.99), which were recruited from 18 gastroenterology departments. 30 PU patients were engaged in the test-retest study. 40 PU patients and 30 gastritis patients joined the discriminate validation study. Results: Two factors, pain factor (PF) and dyspepsia factor(DF), were found by exploratory factor analysis. Reliabilities of the two factors are 0.786 (PF) and 0.753(DF). Validation studies showed that PU patients have significantly higher PUSRS total score (P

5.SELECTIVE TOXICITY OF RHODAMINE 123 ON CARCINOMA CELL IN VITRO
Acta Anatomica Sinica 1953;0(01):-
The selective toxicity of the mitochondria-specific cationic fluorescent dye rhodamine 123 (Rh-123) on HeLa cells in culture was studied. In this report, we demonstrate that with continuous exposure, Rh-123 markedly inhibited the growth of HeLa cells but had little effect on normal human kidney fibroblasts. With continuously exposed to Rh-123, the growth rate, colony forming ability, and mitotic index of HeLa cells were decreased. The mechanism of toxicity of Rh-123 on HeLa ceils was investigated by EM and enzyme cytochemistry stain. The mitochondria of carcinoma cells were the main targets for the inhibitory action of Rh-123, since they selectively accumulated the dye. At the dosage of Rh-123 which was toxic to HeLa cells, the structure and function of mitochondria were disrupted, as the mitochondriarelated enzymes, i. e., ATPase, LDH, and SDH were inhibited. The possible mechanism of the action of Rh-123 on HeLa cells is briefly discussed.
6.Investigate the curative effect on treatment of 40 major aphthous ulcer patients by combined use povidone-iodine,H_2O_ and levamisole liniment
Chinese Journal of Primary Medicine and Pharmacy 2006;0(08):-
Objective To study the curative effect of major aphthous ulcer using povidone-iodine,H_2O_2 asso- ciated with levamisole liniment.Methods The RAU patients were divided into 2 groups randomly.The patients of curative group were instructed to use povidone-iodine,H_2O_2 and levamisole liniment;The control group were in- structed to take metronidazole,antibiotics,compound vitamin B and vitamin C.Then the patients were observed peri- odically.Results The success rate of curative group was 85 % and the control group was 55 %.The difference had statistical significance(P<0.01).Conclusion Treatment of major aphthous ulcer using povidone-iodine,H_2O_2 and levamisole liniment is effective.

Objective To analyze the expression levels of matrix metallo proteinase-2 (MMP-2) and matrix metallo proteinase-9 (MMP-9) in serum of patients with esophageal cancer,and to analyze the interrelations among MMP-2,MMP-9 and clinicopathologic characteristics of esophageal cancer.Methods The levels of serum MMP-2,MMP-9 from 60 patients with esophageal cancer were detected by enzyme linked immunosorbent assay.The interrelations among MMP-2,MMP-9 and clinicopathologic characteristics of esophageal cancer including age,gender,histological type,whether or not lymph nodes metastasis and TNM staging were analyzed.Results The levels of MMP-2 and MMP-9 in control group were 61.31 ng/ml and 87.67 ng/ml,the levels of MMP-2 and MMP-9 in patients with esophageal cancer were 121.66 ng/ml and 169.73 ng/ml.The levels of MMP-2 and MMP-9 were significantly higher in patients with esophageal cancer than that of general population (t =3.015,P =0.007; t =2.037,P =0.04).The level of MMP-2 was significantly associated with whether or not lymph node metastasis (t =2.150,P =0.04) and clinical staging (t =2.186,P=0.03).The level of MMP-9 was significantly associated with whether or not lymph node metastasis (t =2.390,P =0.02) and clinical staging (t =2.149,P =0.03).The levels of MMP-2 and MMP-9 have no reference to age,gender and histological type (all P>0.05).Conclusion MMP-2 and MMP-9 may correlate with tumor invasion and metastasis in patients with esophageal cancer.

Objective To define the characteristic values of the pharyngeal cavity by comparing the values of measures and ratios between the patients with obstructive sheep apnea-hypopnea syndrome(OSAS) and controls.Methods Sixty-eight OSAS patients who were diagnosed using polysomnography,and 56 healthy people were scanned by MSCT(multiple slices computed tomography)in the awake state.Then, the values were measured on the reformated images and were compared between two groups.Results Of the 63 values,49 values were different between the two groups,and among those,4 values were entered into the Discriminant Functions.These were the left-right diameter(LR)[OSAS:LR=(9.4?3.7)mm,controls: LR=(20.1?5.0)mm,t=-13.820,P=0.000)and the cross-sectional area(XSA)[OSAS:XSA= (54?27)mm~2,controls:XSA=(164?77)mm~2,t=-10.944,P=0.000]of RP,the heights of tongue [OSAS:(75.4?8.3)mm,controls:(58.4?9.8)mm,t=10.476,P=0.000],the lengths of uvula/the lengths of airway(OSAS:0.139?0.039,controls:0.154?0.048,t=-1.983,P=0.050).Conclusions Many measures and ratios were different between the two groups,but there were overlaps between them. Measures using the Discriminant Functions can help the diagnosis of OSAS.
