OBJECTIVETo examine the effect of RhoA/Rho kinase signal pathway on TGF-beta1-induced phenotypic differentiation of human dermal fibroblasts.

METHODSThe 4th generation of primary cultured human dermal fibroblasts were stimulated with TGF-beta1, (10 ng/ml). The expression of alpha-SMA was detected after treatment with TGF-beta1, for 0, 3, 6, and 24 h. The expression of alpha-SMA was also detected after treatment with different concentration of TGF-beta1 (0, 2, 10, 50 ng/ml). Then the human dermal fibroblasts (4th generation) were stimulated with TGF-beta1, (10 ng/ml) after being treated with the RhoA/Rho kinase signaling pathway inhibitor Y-27632 (10 umol/ml). The fibroblasts were treated with nothing as sham control, or with Y-27632 (10 umol/L) only as negative control group, or with TGF-beta1 (10 ng/ml) only as positive control group. The expression of alpha-SMA was detected in all the groups. Protein expression was analyzed with ANOVA statistical method.

RESULTSalpha-SMA expression in fibroblasts with 10 ng/ml TGF-beta1 stimulation for 0, 3, 6, 24 h was 1.0, 1.9 0.2, 2.1 +/- 0. 1, 3. 1 +/- 0.1, respectively. Alpha-SMA expression in 24 h group was significantly higher than that in other three groups (n = 4, P < 0.05). alpha-SMA expression in human dermal fibroblasts after stimulation with different concentration of TGF-beta1 (0, 2, 10, 50 ng/ml) was 1.0, 1.4 +/- 0.2, 3.2 + 0.1, 3.1 +/- 0.2, respectively. alpha-SMA expression in 10 ng/ ml group was significantly higher than that in 2 ng/ml group and control group (n = 4, P < 0.05). There was no statistical difference in alpha-SMA expression between 10 ng/ml group and 50 ng/ml group (n = 4, P > 0.05). With both Y-27632 (10 micromol/L) and TGF-beta1 stimulation, the cell phenotype differentiation was inhibited. Alpha-SMA expression in experimental group (1.2 +/- 0.2) was significantly reduced, when compared with that in positive control group (2.9 +/- 0.1) (n = 5, P < 0.05). There was no significant difference (n = 5, P > 0.05) in alpha-SMA expression between control group (1.0) and negative control group (1.1 +/- 0.1).

CONCLUSIONSRhoA/Rho kinase signaling pathway should be involved in TGF-beta1-induced phenotypic differentiation of human dermal fibroblasts.

OBJECTIVETo explore the effects of Huqi Extractum (HQE) on the viability and apoptosis in mouse thymic lymphocytes against 60Co radiation.

METHODSThymic lymphocytes were isolated from 4 -8 weeks healthy male Kunming mice and primarily cultured. Then they were divided into the control group, the irradiation group, the low dose HQE group, the medium dose HQE group, and the high dose HQE group. Equal volume of serum free RPMI-1640 culture solution was added in the control group and the irradiation group, while equal volume of HQE solution (at the daily dose of 25, 50, and 100 mg/mL) was respectively added in the low, medium, and high dose HQE groups. Except the control group, those in the rest groups were exposed radiation at a single dose of 5 Gy gamma-ray. Changes of the thymic lymphocytes' viability were measured by MTT colorimetric assay at 12, 24, 36, and 48 h after radiation. The early apoptosis rate was detected using flow cytometry (FCM) after 10-h radiation. The apoptosis was detected using agarose gel electrophoresis to observe the DNA injury after 24-h radiation.

RESULTSThe viability level decreased more obviously in the irradiation group than in the control group at 24 -48 h after radiation (P < 0.01, P < 0.05). The average viability level was obviously higher in the low, medium, and high dose HQE groups than in the irradiation group (P < 0.05) in a dose dependent manner. The early apoptosis rate was obviously lower in the low, medium, and high dose HQE groups than in the irradiation group, with statistical difference shown in the high dose HQE group (P < 0.01). Typical DNA ladder fragments were found in the electrophoresis in all groups except the control group. But the DNA injury was comparatively milder in the low, medium, and high dose HQE groups, with more obvious effects shown in the high dose HQE group.

CONCLUSIONHQE showed protection for the viability of early thymic lymphocytes exposed to the 60CO radiation, and could lower the early apoptosis level.

OBJECTIVESTo study the correlation between Chlamydiae pneumonia and carotid atherosclerosis, and the correlation between the infection of Chlamydiae pneumonia and ischemic events.

METHODSThe study group consisted of 19 patients who underwent unilateral carotid endarterectomy surgery during the period from January 2010 to December 2011, and the atherosclerotic plaque specimens were harvested from these patients. The control group consisted of 10 patients who underwent extracranial-intracranial bypass surgery during the same period, and the normal external carotid artery specimens were got from these patients. The clinical data between the two groups had comparability. The presence of Chlamydiae pneumonia in atherosclerotic plaque and normal artery tissue were investigated by immunohistochemistry. The expression of Toll-like receptor 2 (TLR2), tumor necrosis factor-α (TNF-α) and vascular cell adhesion molecule-1 (VCAM-1) in the atherosclerotic plaque infected with Chlamydiae pneumonia were also detected. Data were analyzed using Fisher's exact test.

RESULTChlamydiae pneumonia was found in 9 of 19 atherosclerotic plaques, while no positive result was found in control group. The statistical analysis showed a significant difference (P = 0.011). Among the 19 patients in study group, 15 of them had ischemic events, and Chlamydiae pneumonia was found in 9 of these 15 patients; while the other 4 patients didn't have any ischemic events and no Chlamydiae pneumonia was found in them, but there was no statistical different between them (P = 0.087). Through immunohistochemistry, the expression of Chlamydiae pneumonia, TLR2, TNF-α and VCAM-1 were found in same area.

CONCLUSIONSThere is a correlation between Chlamydiae pneumonia and carotid atherosclerosis.And there might be a correlation between Chlamydiae pneumonia and cerebral ischemic events.

OBJECTIVETo evaluate and analyze the mechanism of Pizhen for the treatment of patients with scapular muscle fasciitis.

METHODSOne hundred and sixteen patients were divided into two groups according to random number table method, 58 cases in the treatment group and 58 cases in the control group. After treatment, 109 patients were followed up, and 7 patients lost follow-up (2 cases in the treatment group and 5 patients in the control group). In the treatment group, there were 15 males and 41 females, with a mean age of (28.02 +/- 4.85) years; the course of disease ranged from 0.25 to 3 years; and the patients were treated by Pizhen once a week,and 2 weeks were one treatment course. In the control group, there were 19 males and 34 females, with a mean age of (27.23 +/- 4.54) years old; the course of disease ranged from 0.25 to 1 year; and the patients were treated by acupuncture massage instrument, 20 minutes at a time,once a day for 2 weeks. Soft tissue displacement and banana area were tested by a soft tissue tension tester, pressure value was measured by pressure measuring instrument, and VAS was recorded by pain visual analog scale record.

RESULTSThere were significant differences in tissue displacement, banana area, pressure value and VAS between two groups before and after treatment. The tissue displacement and pressure value in the treatment group were higher than those in the control group,while banana area and VAS were lower than those in the control group. In the treatment group, 30 patients healed, 13 patients got marked improvement, 12 good and 1 poor;while 16 patients healed, 19 patients got marked improvement,11 good and 7 poor in the control group. The therapeutic effects in the treatment group was better than that in the control group.

CONCLUSIONPizhen is an effective method to treat pain in patients with scapular muscle fasciitis by relaxing tendon of soft tissue around pain point of scapular and relaxing compress and stimulation of nerves.

Stress in medical education has been inevitable among medical students. However, the prevalence of stress among pre-clinical and clinical medical students differed by year of study. There were several stressors reported to affect medical students. Therefore, effective coping strategies were applied to manage the stress faced by medical students. The aim of this study was to determine the prevalence of stress, stressors and coping strategies comparing pre-clinical and clinical Universiti Tunku Abdul Rahman (UTAR) medical students, and the associated stressors and stress among them. This was a cross-sectional study with a study population of 223 medical students. Universal sampling was used. A self-administered questionnaire which included socio-demographic characteristics, the General Health Questionnaire (GHQ-12), the Medical Students Stressor Questionnaire (MSSQ) and the Brief COPE Inventory were used in this study. The overall prevalence of stress among medical students was 48.15%. Clinical students had a higher prevalence of stress (53.73%) compared to pre-clinical students (39.02%). Year 3 students had the highest prevalence of stress (64.58%) compared to other years of study. Nearly 1 out of 2 medical students were stressed (48.15%). Academic Related Stressor ranked the highest and Acceptance was the most practiced coping strategy. The only associated stressor with stress was Academic Related Stressor.

Objective To analyze the precipitating factors for,clinical manifestations of,laboratory findings in and therapeutic effect on acute urticaria.Methods Clinical data were collected from 185 inpatients with acute urticaria in Shanxi Dayi Hospital from January 2013 to December 2016.Clinical features,laboratory examination results,treatment,prognosis and adverse reactions were analyzed retrospectively.Statistical analysis was carried out by chi-square test.Results There were 63 male patients and 122 female patients in this study,with an average age at onset of 32.87 ± 14.18 years.Of the 185 patients,78 (42.2％) were able to report the aetiological agents accurately,33 (17.8％) were induced by infection or drug therapy following infection,and 82 (44.3％) had fever.Blood cell analysis showed increased white blood cell count in 132 (71.4％) cases and increased proportion of neutrophils in 128 (69.2％) cases.The level of C reactive protein increased in 118 (69％) of 171 cases.A total of 185 patients received routine anti-anaphylactic treatment.Of 183 cured patients,153 (83.6％) were treated with antibiotics,26(14.2％)with antibiotics alone,and 24(13.1％) with azithromycin.There were 127 (69.4％) patients receiving combined treatment with glucocorticoids,antibiotics,and so on,and the antibiotic used in 111 (60.7％) cases was azithromycin.Of 88 cured patients with simultaneous signs of infection,85 (96.6％) showed increased levels of part or all of infection markers (including the white blood cell count,proportion of neutrophils and level of C reactive protein),and 69 (78.4％) were treated with azithromycin.Of 95 cured patients without signs of infection,83 (87.4％) showed increased levels of infection markers,and 61 (64.2％) were treated with azithromycin.Moreover,there were significant differences in the proportion of patients with increased levels of infection markers and that of patients treated with azithromycin between the cured patients with and without signs of infection (x2 =5.164,4.476,both P ＜ 0.05).Conclusions Infection is a common cause of acute urticaria,and laboratory examinations including white blood cell count,proportion of neutrophils and level of C reactive protein are of important reference value to the diagnosis of infection in patients with acute urticaria.Patients with signs of infection or increased levels of infection markers need to be treated with combined anti-infective therapy,and in the cured patients,the proportion of patients administrating azithromycin was higher than that of those administrating other antibiotics for the treatment of acute infectious urticaria.

OBJECTIVETo summarize the surgical effect and clinical application value of esophagectomy with extended 2-field lymph node dissection for patients with esophageal carcinoma.

METHODSFrom June 1987 to December 2008, 1690 patients with esophageal cancer underwent esophagectomy with extended 2-field (thoracic and abdominal) dissection of lymph nodes. Patients with the middle and lower thoracic esophageal cancer underwent Ivor-Lewis esophagectomy, and patients with upper thoracic esophageal cancer underwent Akiyama esophagectomy. 2-field (thoracic and abdominal) lymph node metastases information and the 1, 3, 5, 10-year survival rates were analyzed retrospectively.

RESULTSLymph node metastases were found in 713 patients. The lymph node metastases rate was 42.2% (713/1690).Thoracic lymph node metastasis rate was 39.3% (665/1690), among which in the right pleural apical para-tracheal triangle was 20.7% (349/1690), in the posterior upper mediastinum was 26.3% (444/1690), in the lower mediastinum was 18.2% (307/1690). Abdominal lymph node metastasis rate was 20.1% (339/1690). THE Postoperative complication rate was 16.4% (278/1690), among which the pulmonary complication rate ranking the first, was 43.6% (136/312). The operative mortality rate was 0.2%. The 1-year, 3-year, 5-year and 10-year survival rates were 88.2% (1388/1574), 63.5% (868/1367), 54.8% (705/1287) and 30.8% (232/754), respectively. The 5-year survival rate in patients without lymph node metastasis was 76.2% (448/588), but that in patients with lymph node metastases was 36.8% (257/669).

CONCLUSIONThe results of this study demonstrated that Ivor-Lewis and Akiyama esophagectomy with two-field lymph node dissection exposes the operation fields clearly and make radical lymphadenectomy thoroughly, especially the lymph nodes in the posterior upper mediastinum around the recurrent laryngeal nerve and in the right pleural apical para-tracheal triangle. It is essential that patients with esophageal carcinoma with lymph node metastases should undergo esophagectomy with extended 2-field dissection of lymph nodes. This can elevate the postoperative 5-year survival rate remarkably.
