BACKGROUNDTo investigate the clinicopathological significance of c-kit protein expression in small cell lung cancer (SCLC).

METHODSc-kit protein expression was detected in 52 formalin-fixed and paraffin-embedded SCLC, 20 non-small cell lung cancer (NSCLC) and 10 normal lung tissues by immunohistochemistry with rabbit antibody to human c-kit protein.

RESULTSc-kit protein was expressed in 61.5% (32/52) of primary SCLC, but negative in all 20 samples of NSCLC and 10 normal lung tissues. c-kit protein was localized in cytoplasm of cancer cells. The expression of c-kit protein was related to tumor size ( P =0.010) and prognosis ( P =0.000 1), but not to sex ( P =0.208), age ( P =1.000) or TNM stage ( P =0.722) of SCLC.

CONCLUSIONSc-kit protein expression may be corresponding to the prognosis of SCLC. Since in situ detection of c-kit protein is more direct than the other methods, it is helpful to clinicopathological diagnosis, targeted therapies interacting with c-kit signaling pathway and prognostic assessment in SCLC.

AIM: To investigate the feasibility of reendothelialization of the injured arterial wall by autologous endothelial cell transplantation and their influences on neointima proliferation. METHODS: New Zealand white rabbits (n=30) were subjected to bilateral iliofemoral artery balloon injury. Cultured, autologous venous endothelial cells were immediately transplanted into one vessel(transplantation group), whereas the contralateral artery received medium only(control group). Reendothelialization of the injured arterial wall was analysed 4 hours or 4 days after cell transplantation by fluorescent tracing、scanning electron microscope(SEM) and Evans blue staining. Pathology analysis was employed 28 days after cell transplantation to evaluate neointima proliferation. RESULTS: The transplanted endothelial cells had adhered into the aterial wall 4 hours after transplantation and began to attach and spread 4 days later. A number of fluorescent labeling endothelial cells were observed in the endothelial injured arterial wall. The vessels in control group were stained nearly completely by Evans blue, whereas about 60% area was not stained in transplantation group. Pathological examination demostrated that neointimal area and maximal intima thickness in transplantation group significant decreased than those in control. CONCLUSION: Autologus endothelial cells were effectively transplanted into the injured arterial wall by balloon catheter, and it can relieve neointima proliferation in the long time.

OBJECTIVETo observe the effectiveness and safety of external applying Compound Tripterygium wilfordii Hook F. (TwHF) in relieving joint pain in rheumatoid arthritis (RA) patients.

METHODSIn this double-blinded, randomized multicenter trial, a total of 174 moderately active RA patients were enrolled and randomly assigned to the treatment group (treated with Compound TwHF, 87 cases) and the placebo control group (87 cases). Compound TwHF or placebo was externally applied in painful joints, 20 g each time, once per day for 8 weeks. Self-reported joint pain relief was taken as a primary effective indicator. Visual analogue scale for pain (VAS), disease activity score of 28 joints (DAS28), VAS for general health (GH) were evaluated before treatment, at week 4 and after treatment. Erythrocyte sedimentation rate (ESR) and hypersensitive C reactive protein (hs-CRP) were tested before and after treatment. Menstrual changes in females were observed during treatment. Skin irritation occurred during the recording process was assessed using skin irritation strength. Intention to treat (ITT) was statistically analyzed.

RESULTSThe joint pain relief rate in the treatment group was 90.8% (79/87 cases), higher than that in the placebo control group (69.0%, 60/87 cases; P = 0.001). VAS pain score, DAS28, VAS for GH score were significantly improved in the two groups at week 4 of treatment and after treatment, as compared with before treatment (P < 0.01). ESR and hs-CRP levels significantly decreased in the treatment group after treatment (P < 0.05, P < 0.01). No difference was found in post-treatment VAS pain score, DAS28, VAS for GH score, ESR, or hs-CRP between the two groups (P > 0.05). Eight adverse events occurred in the treatment group (5 skin allergy, 1 intolerance of medical odor, and 2 mild liver injury), while 3 adverse events occurred in the placebo control group (2 skin allergy, 1 mild liver injury). There was no statistical difference in adverse event between the two groups (P > 0.05). No menstrual change occurred in the treatment group.

CONCLUSIONExternal applying Compound TwHF was an effective and safe way to relieve-joint pain of RA patients, which could be taken as an adjuvant therapy.

Objective To study the effect of intensive trunk muscle training on balance and walking in pa- tients with hemiplegia caused by stroke.Methods A total of 90 stroke patients were recruited and randomly divid- ed into a treatment group(45 cases)and a control group(45 cases).All the patients were given conventional reha- bilitation training.Meanwhile,intensive trunk muscle training was also administered for those in the treatment group as well.The trunk control function,balance ability and walking ability were assessed by using the trunk control test, Berg Balance Scale and the balance subscale of the Fugl-Meyer physical performance test,and Holden's functional ambulation classification,respectively,before and after 6 weeks of training.Results It was found that all the pa- tients scored better with the trunk control test,Berg's balance scale,the balance subscale of the Fugl-Meyer physical performance test and Holden's ambulation classification after treatment,and there were significant differences between the two groups after treatment(P

Differentiating arrhythmogenic right ventricular dysplasia/cardiomyopathy (ARVD/C) from other cardiomyopathies is clinically important but challenging. Although the modified Task Force Criteria can facilitate diagnosis of ARVD/C according to clinical manifestations, histopathological examination plays a pivotal role in excluding other diseases that can mimic ARVD/C. Here, we report a patient with amyloidosis that initially presented similarly to ARVD/C. The diagnosis was confirmed by endomyocardial biopsy, and catheter ablation eliminated the ventricular tachyarrhythmias through an epicardial approach.

OBJECTIVETo investigate the effect of Qingre Huoxue decoction, (QRHX) on radiographic progression in patients with rheumatoid arthritis (RA) with X-ray imaging.

METHODSFrom July 2007 to March 2009, 86 patients with active RA who were diagnosed as damp-heat and blood stasis syndrome were randomly divided into QRHX group and QRHX plus methotrexate (MTX) group, 43 cases in each group. Patients in the QRHX group were treated with QRHX decoction [composed of Huangbai, Chishao, Bixie, Danshen, Ezhu, Qingfengteng, raw Huangqi, Jinyinhua, Tufuling, Wugong, Fengfang, raw Yiyiren, which was cooked with water as 400 ml liquid); while patients in the other group were treated with QRHX decoction plus MTX. After one-year observation, 21 patients in each group (42 in total) were evaluated,with 19 females in QRHX group, average age of (43.0 +/- 11.3) years, and the course of the disease was 2 (1,3) years; and 18 females in QRHX+MTX group, average age of (44.5 +/- 14.0) years, and the course of the disease was 3 (1.7, 5) years. Radiographs of hands were obtained at baseline and 12 months after treatment. Images were evaluated by investigators blinded to chronology and clinical data, and assessed according to Sharp/van der Heijde methods.

RESULTSHigh intrareader agreements were reached (mean intraobserver intraclass coefficients: 0.95). No significant change in any imaging parameters of joint destruction was observed at 12 months after treatment in both groups; and there were no statistical differences between the two groups (P > 0.05). The severity of progress in two groups was also similar (P = 0.46), 7 patients without radiographic progress in QRHX group and 8 patients in QRHX+MTX group,3 patients with obvious radiographic progress in QRHX group and 1 patient in QRHX+MTX group.

CONCLUSIONRadiographic progress of RA patients in two groups is similar, indicating QRHX decoction has a potential role in preventing bone destruction.

OBJECTIVETo investigate the effects of Qingre Huoxue Decoction , clearing heat and promoting blood flow; QRHXD), on the radiographic progression in patients with rheumatoid arthritis (RA) by X-ray imaging.

METHODSEighty-six patients with active RA diagnosed as damp-heat and blood stasis syndrome were randomized into a QRHXD group and a QRHXD plus methotrexate (MTX) group, with 43 cases in each group. After one-year of treatment, 21 cases in each group (42 in total) were evaluated. Radiographs of hands were obtained at the baseline and after 12 months of treatment. Images were evaluated by investigators blinded to chronology and clinical data, and assessed according to the Sharp/Van der Heijde methods.

RESULTSHigh intrareader agreements were reached (mean intraobserver intraclass coefficients: 0.95). No significant change in any imaging parameters of joint destruction was observed at 12 months in either group; and the differences between the two groups were not significant (P>0.05). The mean of the changing score in the QRHXD group was 3.5 ± 4.1, and 2.4 ± 3.5 in the QRHXD+MTX group, while the baseline radiographic score of patients in the QRHXD group was relatively higher (18.9 ± 19.1 vs. 14.0 ± 14.0). The mean rates of the changing scores of the two groups were similar (0.24 ± 0.28 vs. 0.25 ± 0.44, P=0.40). The severity of progression in the two groups was also similar (P=0.46), 7 cases without radiographic progression in the QRHXD group and 8 in the QRHXD+MTX group, 3 cases with obvious radiographic progression in the QRHXD group and 1 in the QRHXD+MTX group.

CONCLUSIONRadiographic progression of RA patients in both groups is similar, indicating that the QRHXD Decoction has a potential role in preventing bone destruction.

OBJECTIVETo explore the endoscopic and histopathological morphology of large intestinal serrated adenomas (SA).

METHODSThe endoscopic and pathological data of 71 SA patients, diagnosed in the Digestive Endoscopy Center, Nanfang Hospital from January 2002 to July 2005, were analyzed retrospectively.

RESULTSForty-seven of the 71 serrated adenomas were protruded (sessile 23, semipedunculated 5, pedunculated 23) and 24 were superficial (flat 16, laterally spreading 8). The mean sizes of the protruded and superficial SA were 10.5 mm and 16.6 mm, respectively, and both of them were frequently located in the sigmoid and rectum. Histopathologically, SA contained tubular glands in 53, tubulovillous glands in 9 and villous glands in 9 cases. Mild dysplasia was found in 47 SAs, moderate dysplasia in 22 SAs, and canceration foci in 2 SAs. The dysplasia of SAs (<10 mm) was significantly better than that of SAs (>or= 10 mm) (P< 0.01). Most IV and III L pit SAs presented villous glands (64%) and tubular glands (68%), respectively. 40% of hyperplastic polyps-like SAs, composed of tubular glands,showed II pit pattern. Atypia in II pit SAs was similar to that in IIIL pit SAs, but was worse than that in IV pit SAs.

CONCLUSIONPolyps with II pit pattern possibly are SAs sometimes. SA with the common characters of neoplastic polyps,should be regarded as a new potential precancerous lesion.
