AIM: To elucidate the change in TFF3 mRNA in the lung tissue in chronic obstructive pulmonary disease (COPD) rats. METHODS: A model of rat COPD was established by passive cigarette smoking and intratracheal instillation of lipopolysaccharide. The expression of TFF3 mRNA in the lung tissues was detected by reverse transcription-polymerase chain reaction (RT-PCR). RESULTS: Through a semi-quantitative pathological analysis, mean lung internal lining interval (MLI) in COPD model group was significantly increased compared with healthy control groups; mean alveolar number (MAN) in COPD model group was significantly decreased compared with healthy control group. The expression of TFF3 mRNA decreased significantly in the lung tissue in COPD model group compared with healthy control group. CONCLUSION: The level of TFF3 mRNA expression is possibly related with lung tissue lesion in COPD rats. [

Objective To analyze the mid- and long-term results after coronary artery bypass graft surgery (CABG), to evaluate the accuracy of multi-detector CT coronary angiography (MDCT) on the graft patency status and to compare the patency for different grafts. Methods One hundred and one cases underwent CABG from June 1992 to March 2008 were followed up by searching the database of MDCT (42 cases) and selective coronary angiography (SCA, 59 cases). The mean following up period was (66.79 ±44.27) months. Three hundreds and 10 grafts including 115 arterial and 195 venous were analyzed.A comparison of the patency rate between the arterial and venous grafts was also carried out. At the mean time, 2 groups were divided according to the paft lesions( patency of not). Uunivariate analysis and Logistic regression analysis were made for statistics. Results At the follow-up of (53.93 ± 36.80) months, the patent rate of LIMA, RA, SV and CV examined by MDCT was 94.7%, 92.0%, 85.9% and 60.0%, respectively. The patent rate for MDCT patients with angina was 83.5%, and 95.2% for angina-free group ( P = 0.046). At the follow-up of (75.95 ±47.09) months, the patent rate of LIMA, RA, SV and CV examined by SCA was 87.1%, 81.0%, 53.6% and 57. 1%, respectively. In SCA patients the patent rate was 62.0% for angina group and 100% for angina-free group ( P = 0.025 ). According to logistic regression analysis, only the postoperative period was statistically related to the graft lesion. Conclusion MDCT could find out the occlusions and obvious stenoses of the grafts after CABG. It might be served as a noninvasive method to evaluate the grafts patency postoperatively. The mid- and long-term patency of arterial grafts is better than venous grafts. Graft lesion is an important factor leading to postoperative recurrent angina pectoris. The severity of the graft lesion has a close relation to the lenth of postoperative period.

OBJECTIVETo evaluate radial artery (RA) and internal mammary artery (IMA) grafts in coronary artery bypass and the use of color Doppler ultrasound in the peri-operative evaluation of IMA and radial-ulnar collateral circulation.
METHODSFrom June 1998 to June 2000, sixty cases of coronary bypass revascularization with RA and IMA were performed. Preoperatively, the radial-ulnar collateral circulation was evaluated with the modified Allen's test, color Doppler ultrasound and noninvasive oxygen saturation measurement. The IMA lumen and blood flow were measured at the first intercostal space with color Doppler ultrasound preoperatively and postoperatively.
RESULTSOne patient (1.7%) died of serious cardiac arrhythmia on the fourth postoperative day. There were no arterial graft harvest related complications. Before harvesting, the ulnar artery blood flow was 30.78 +/- 9.71 ml/min, and it increased to 43.36 +/- 13.98 ml/min (40.87% increase, P < 0.01) after the operation. Compared with the baseline, there was no obvious change of IMA blood flow postoperatively (P > 0.05), but the systolic/diastolic flow ratio markedly decreased from 8.57 +/- 3.98 ml/min to 3.41 +/- 4.87 ml/min (P < 0.01).
CONCLUSIONSArterial grafts can be safely used for coronary bypass revascularization with good results. The ulnar artery blood flow can increase compensatively after RA harvesting. The diastolic blood flow of grafted IMA markedly increased postoperatively. Color Doppler ultrasound was very helpful both in evaluating the radial-ulnar collateral circulation before RA harvesting and in assessing the patency of the grafted IMA after coronary artery bypass grafting (CABG).

Objective:To observe the clinical effects of hot-wet compression with Xiaohua ointment for acne mastitis in mass stage and its impacts on humoral immune function and inflammation.Methods:85 cases of patients with acne mastitis in mass stage treated in our hospital from January 2018 to January 2019 were selected as the research objects and randomly divided into control group (42 cases) and observation group (43 cases). The control group taken Tuoli xiaodu powder and external use of purple detumescence cream, and the observation group received hot-wet compression with Xiaohua ointment additionally. All treated for 30 days. The clinical efficacy, symptom scores, breast mass size, humoral immune indexes, C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) were compared, and the adverse reactions were recorded.Results:After treatment, the humoral immune indexes of the two groups had no significant change ( P>0.05), but the pain score, breast tumor size, mass score, CRP and ESR were significantly decreased than those before treatment ( P<0.05); compared with the control group, the pain score, breast tumor size and mass score in the observation group were significantly lower than those in the control group ( P<0.05). The total effective rate of the observation group was 83.7%, which was significantly higher than 59.5% of the control group ( P<0.05). There were no obvious adverse reactions in both groups. Conclusions:Hot-wet compression with Xiaohua ointment is effective and safe for patients with acne mastitis in mass stage, and could improve their inflammation.

Objective:To investigate the clinical features of neonatal testicular torsion and to evaluate the effect and necessity of early intervention.Methods:A retrospective analysis was performed on 11 neonates admitted to the Second Hospital of Shandong University with neonatal testicular torsion from June 2017 to June 2022. Clinical data of these cases including clinical manifestations, ultrasonography findings, surgical management and outcomes were reviewed and analyzed with descriptive statistical methods.Results:The median age of the 11 patients on admission was 2.6 d (1-5 d). The median time from finding abnormal scrotum to admission was 12 h (1-120 h). Various degrees of scrotal swelling or scleroma were found in the patients. Among them, seven patients presented with acute inflammatory signs of cyano sis or skin redness, and testis-like tissue induration could be touched. Ultrasound scan showed abnormal blood flow in the affected testicle in all cases. Emergency scrotal exploration under general anesthesia was performed successfully in all cases and ten of them underwent orchiectomy of the affected testicle plus contralateral orchiopexy. The rest one who was admitted within 1 h after birth only underwent orchiopexy of the affected testicle as the parents refused contralateral testicular exploration. During the operation, 12 twisted testis were observed, including seven with extravaginal torsion, three with intravaginal torsion and two adhering to the surrounding tissue without normal testicular tissue or distinguishable torsion direction or degree. In this study, ten patients had unilateral testicular torsion, which affected the left side in seven cases and the right side in three cases, and one had bilateral testicular torsion, which was diagnosed as left testicle torsion before surgery. During scrotal exploration, the left testicle of this bilateral case was resected due to necrosis, while the right testicle twisted about 180 degrees with good blood flow and was subjected to orchidopexy after reduction. In one case, the unaffected testicle was unfixed and dysplastic during contralateral exploration, which was also subjected to orchidopexy. In the 12 testis with torsion, one testicle of the patient admitted within 1 h after birth and the right testicle of the bilateral case were preserved with a salvage rate of 2/12. Pathological examination showed necrosis in the ten excised testis, and fibrosis and calcification foci in two of them. None of the patients had any perioperative complications and the scrotal incision healed well in all neonates. The patients were followed up for 6-12 months with regular ultrasound. The two preserved testis and the contralateral testis subjected to orchidopexy were located in the scrotum with good blood supply, and no torsion, atrophy or other abnormalities occurred.Conclusions:Neonatal testicular torsion is rarely seen in clinical practice and has no specific manifestations. It has a high excision rate due to testicular necrosis. Early diagnosis and bilateral scrotal exploration are crucial to the prognosis and the keys to save the affected testis and avoid anorchidism.
