Crohn's disease(CD) is a lifelong disease and the precise aetiology is still unknown.Differences in the definitions and diagnosis between clinicians make direct influence on therapeutic efficacy on CD.This article overviewed the progresses on the definitions such as staging,relapse,and diagnosis of Crohn's disease in these years in order to decrease the mistakes and be helpful to institute sensible and effective therapeutic regimen.

Objective To evaluate the clinical value of CT-guided interstitial implantation of ~(125)I seeds for the treatment of pulmonary carcinoma. Methods A total of 18 patients with pulmonary carcinoma underwent CT-guided interstitial implantation of ~(125)I seeds. According to the size of tumor,effective dose, and optimal quantity of ~(125)I seeds to the patient that were computed by a developed algorithm in Treatment Planning System (TPS), the ~(125)I seeds were implanted into the tumor tissues under the guidance of spiral CT. The patients were reexamined by CT 2 months after the operation and were followed up for 6 months. Results A total of 812 seeds were implanted into the 18 lesions in the 18 cases (45.1 seeds per case in average). The CT scan performed 2 months after the operation showed CR in 7 cases, PR in 10, and NC in 1. The total effectiveness (CR+PR) rate was 94% (17/18). Conclusions CT-guided interstitial implantation of ~(125)I seeds is a effective, minimally invasive, and low toxic method for valid and minimally traumatic treatment for middle- and late-stage lung cancer. Further application and long-term observation are necessary.

TNF-?,a pleiotropic cytokine with strong proinflammatory and immunomodulatory properties is known to play an important role in inflammatory bowel disease(IBD).The biological effects of TNF-? are elicited by binding to its two cognate recepters,TNFR1 and TNFR2.For a long time,TNF-R1 was considered to be the predominant mediator of TNF-signaling,whereas TNF-R2 was ascribed only auxilliary function.However,there is increasing clinical and experimental evidence for an important independent role of TNF-?/TNFR2 signaling in chronic inflammatory conditions of IBD.The elucidation of the different effects of TNF-signaling in IBD will lead to a better understanding ot the pathogenesis of these diseases and will be the basis for the development of more specific and more efficient therapeutic approaches.

Objective To observe the clinical efficacy of Tiao Shen Ding Zhi (mind-regulating) needling method in treating anxious neurosis. Method Fifty-eight patients with anxious neurosis were randomized into a treatment group and a control group, 29 in each group. The treatment group was intervened by Tiao Shen Ding Zhi needling method, while the control group was by conventional needling. The total effective rates of the two groups were observed. Result The total effective rate was 96.5% (28/29) in the treatment group versus 82.8% (24/29) in the control group, and the difference was statistically significant (P<0.05). Conclusion Tiao Shen Ding Zhi needling method can produce a higher total effective rate than conventional acupuncture in treating anxious neurosis.

Objective To observe the clinical efficacy of skin needling plus flash cupping for hemifacial spasm. Method Forty patients were randomized into a treatment group and a control group, 20 in each group. For both groups, the following acupoints were selected: Baihui (GV20), Sishencong (EX-HN1), Yifeng (TE17), Xiaguan (ST7), Cuanzhu (BL2), Yangbai (GB14), Taiyang (EX-HN5), Quanliao (SI18), Jiache (ST6), Dicang (ST4), Hegu (LI4), and Waiguan (TE5). Skin needling plus flash cupping was used for the treatment group, while even reducing-reinforcing needling method was used for the control group. Seven-day treatments were considered as a treatment course, and the therapeutic efficacy was analyzed after 3 courses. Result The cure rate was 65.0%in the treatment group versus 45.0% in the control group, and the difference was statistically significant (P<0.05). Conclusion Skin needling plus flash cupping can produce a significant efficacy in treating hemifacial spasm, better than ordinary needling method.

Objective To assess the usefulness of left ventricular contrast echocardiography in diagnosis of left ventricular myocardium noncompaction.Methods Contrast echocardiography was done in ten patients who were diagnosed or suspected with left ventricular noncompaction by common transthoracic echocardiography,for further study of the trabecular muscles extent,the continuity of the endocardium,the compact myocardium thickness,and the contrast agent in the trabecula recessus.Results By contrast echocardiography,noncompaction myocardium thickness can be perspicuously observed,the turgor of the contrast agent was vividly detected in the trabecular recessus.Especially for the measurement of compaction myocardium,the contrast echocardiography was more accurate than in the condition of the common echocardiography.Conclusions Left ventricular contrast echocardiography can be used in the diagnosis of left ventricular noncompaction,it was a good added method of conventional echocardiography.

Objective To detect the expression of type Ⅰ collagen, type Ⅲ collagen, prolyl-4-hydroxylases (PH4) and matrix metalloproteinase 1 (MMP-1) in sacral ligament fibroblasts under stress, to understand the collagen synthesis and metabolism in stress situations change. Methods Eight patients who underwent abdominal hysterectomy for uterine benign disease were enrolled in this study. Primary sacral ligament fibroblasts were isolated by explant. After mechanical loading, gene expression of type Ⅰ , Ⅲ collagen, PH4 and MMP-1 were measured. Results Stress of 8% continuing for 24 hours, collagen Ⅰ (1. 13 ± 0.24), collagen Ⅲ (1.05 ± 0. 31) mRNA expression and PH4 expression (1.11 ± 0. 31) compared with static groups (1) showed increasing trends;when the stress were 4% and 12%, collagen Ⅰ (0. 86 ± 0. 26 and 0. 85 ± 0. 25), collagen Ⅲ showed increasing trends (0. 74 ± 0. 29 and 0. 83 ± 0. 38) mRNA expression were decreased. After removal of the stress, in the stress of 4% for 1 hour, collagen Ⅰ (0.79±0.40, 0.97±0.24 and 1.46 ±0.75), collagen Ⅲ (0.86±0.40, 0.99±0.60 and 1.59±0.82) and PH4 (1.11 ±0. 51, 1.17 ±0. 54 and 1.37 ±0. 39) mRNA expression increased gradually. In 8% stress group, collagen Ⅰ mRNA expression (1.16 ± 0. 62, 1.01 ± 0. 51 and 1.05 ± 0. 80) reached the peak in day 1, and collagen Ⅲ (0.99 ±0.69, 1.59 ±0.55 and 1.03 ±0.91) and PH4 (1.05 ±0.31, 1.07 ±0. 80 and 0. 85 ±0. 31) mRNA expression reached the peak in day 2, then decreased. 4% and 8% of the stress with time after the change, MMP-1 mRNA expression have peaked at day 1. Conclusions Moderate stress could contribute to pelvic floor collagen synthesis, too much or too little stress is not conducive to the synthesis of collagen. Collagen Ⅰ and collagen Ⅲ on the stress response may be different, the former have faster reaction than the latter. PH4 were involved in the synthesis of collagen, while MMP-1 may play a role in collagen degradation.

Objective To study abnormal defecation in patients with posterior vaginal prolapse combined with anorectal manometry. Methods From Jan. 2008 to Nov. 2009, clinical documents and examination of anorectal manometry of 40 patients with posterior vaginal prolapse were studied retrospectively. Anal physiologic testing was performed for 40 patients. These patients were classified into group A ( stage 0 and [posterior vaginal prolapse, represented normal) and group B ( stage Ⅱ - Ⅳ ).Results of anorectal manometry, constipation and symptoms of defecation were compared. Results The average anal canal resting pressure and squeeze pressure of 40 patients were (40 ±21 ) and (96 ±33) mm Hg (1 mm Hg =0. 133 kPa). In group A, the anal canal resting pressure and squeeze pressure were (37 ±21) and (78 ±43) mm Hg, rectal sensation threshold and rectal maximum volume were (106 ±61 ) and (183 ± 51 ) ml. In group B, the anal canal resting pressure and squeeze pressure were (42 ± 21 ) and (102±30) mm Hg, rectal sensation threshold and rectal maximum volume were (90±44) and (171 ±61) nl.Apart from maximum squeeze pressure ( P = 0. 039 ), the other clinical index did not show statistical difference (P ＞ 0. 05 ). Rectal sensation threshold, intended volume and maximum capacity of (116 ± 69 ),( 170 ± 90), ( 191 ± 75 ) ml in patients with constipation were higher than (84 ± 31 ), ( 121 ± 37 ), ( 169 ±45) ml in patients without constipation. In addition to maximum capacity (P = 0. 281 ), the other clinical index reached statistical difference between patients with and without constipation (P ＜ 0. 05 ). Patients with defecation symptoms have higher rectal sensation threshold, intended volume and maximum capacity than those of patients without defecation symptoms. Conclusions As gradually increased in the degree of prolapse, resting pressure and squeeze pressure tend to be increased, while the rectal sensation threshold and rectal maximum volume tend to be decreased. Patients with defecation symptoms and constipation have increased the initial feeling of volume and maximum tolerated volume.

Objective To make sure whether Bcrp1 is the marker of cervical cancer stem-like cells or not by studying the characterization of Bcrp1+ HeLa cells.Methods Immunofluorescence stained flow cytometry and electron microacope were used to sort and observe uhrastructures of Bctp1+ and Bcrp1- HeLa cells.Flow cytometry wag used to identify the cycle and the rate of apoptosis with annexin V in two group cells.The expression of proliferating cell nuclear antigen (PCNA)and caspase-3 were tested using western blot methed.Results (1)There were 7.1% Bcrp1+ cells and 92.9% Bcrol- cells in HeLa cells.Bcrp1+ HeLa cells were large in size of nuclear and nucleoli are clear.and there were rich of cytomicrosome and rough endoplasmic reticulum.After sorted and cultured for 24,48,72 hours,the adhesion in Bcrp1+ cells were 72.8%,81.1%,80.4%,respectively.While,they were 3.3%,18.7%,12.6%at each time for Bcrpl- cells(all P<0. 05 ). (2) There are more S phase cells in Bcrp1+ cells than that in Bcrp1- cells (54. 1% vs 21.1%, P <0. 05) ,while the percentage of G0/G1 and G2/M in Bcrp1 - cells were highter than those in Bcrp1 + cells (53.0% vs 44. 4% ,25.9% vs 1.5% ; all P <0. 05 ). The rate of apoptosis in Bcrp1+ cells was lower than that in Bcrp1 - cells (0. 2% vs 5.3%, P < 0. 05 ). ( 3 ) The expression of PCNA in Bcrp1 + cells was higher than that in Bcrp1- cells (3140 vs 2255, P< 0. 05 ), while the expression of caspase-3 of Bcrpl + cells was lower than that in Bcrp1 - cells ( 1970 vs 3551, P < 0. 05 ).
