OBJECTIVETo investigate the course of coronary artery lesions caused by Kawasaki disease, and the value of coronary angiography (CAG) and two-dimensional echocardiography (2-D Echo) in the evaluation and follow-up of coronary artery lesions.

METHODSEighty seven patients with coronary artery lesions caused by Kawasaki disease from 1979 to 1997 were retrospectively analyzed. One hundred and sixty-seven CAGs were performed in 87 patients during follow-up. CAG was repeated every 1-3 years in each patient until complete regression was confirmed. 2-D Echo was performed before CAG each time. The longest period of follow-up was 16 years and 6 months. Patients were treated with aspirin or aspirin and warfarin.

RESULTSDuring follow-up, the coronary artery lesions regressed in 48/87 (55%) patients, however, they developed into severe coronary artery lesions in 6/87 (7%) patients in whom coronary artery bypass surgery was performed. The coronary artery aneurysm regressed in some patients, while stenotic lesions remained or developed. The ratio of coronary artery stenotic lesions to aneurysms increased progressively. This study showed that Echo diagnosis of coronary artery lesions has "false positives" and "false negatives". Only 76% of coronary aneurysms and 18% of stenotic lesions could be found by 2-D Echo. No stenotic lesion could be found in distal segments of the coronary artery.

CONCLUSIONSLong term follow up revealed spontaneous regression occurred in 55% of patients and development into severe coronary artery stenosis in 7%. It is necessary to perform long-term follow-up in patients with coronary artery lesions caused by Kawasaki disease. 2-D Echo can not completely replace CAG during follow-up of coronary artery lesions caused by Kawasaki disease.

OBJECTIV E To study composition an d content changes of volatile components during the bleaching process of Atractylodis macrocephala with the water of washing rice. METHODS The raw products of A. macrocephala and bleached products of 5 different bleaching stages were prepared （in the first and second stages ，raw products were bleached with 9-fold volumn of the water of washing rice for 12 h and 24 h，respectively；in the third ，fourth and fifth stages ，the raw products were firstly bleached with 9-fold volumn of the water of washing rice for 24 h，and then bleached with 9-fold volumn of clean water for 12，24 and 48 h，respectively）；the bleaching temperature was set at 26 ℃. The volatile components of raw products of A. macrocephala and its bleached products of 5 different bleaching stages were qualitatively analyzed by using headspace gas chromatography-mass spectrometry. The relative percentage of each component was calculated by peak area normalization method. RESULTS A total of 49 volatile components were identified from raw products of A. macrocephala and its bleached products of 5 different bleaching stages，including 20 common volatile components such as terpinolene ，cyperene and atractylon ，etc. Among them ，33，31，28， 30，28 and 29 volatile components were identified from the raw products of A. macrocephala and the bleached products of the first to fifth stages ，the relative percentages of which were 66.218％ ，64.711％ ，79.410％ ，65.419％ ，67.101％ ，66.818％ ， respectively；among them ，the relative percentage of atractylon in bleached products was the highest in the fourth stage （41.206％），but was the lowest in the third stage （35.926％）. Compared with the raw product ，16 volatile components such as pethylbrene and β-vetivenen were added in the bleaching process ，while 8 volatile components such as ethyl palmitate and β-maaliene were not detected. However ，5 volatile components including 11-rotundene and （－）-valeranone in the bleaching process showed a trend of disappearance-emergence and disappearance-emergence-disappearance. CONCLUSIONS In the third stage，the total relative percentage of each volatile component and the relative percentage of representative dry component as ， atractylone are the lowest in bleached products of A. ； macrocephala，i.e. the bleaching technology of relieving the dry property of A. macrocephala e with the water of washing rice is bleaching with 9-fold volumn of the water of washing rice for 24 h，and then bleaching with 9-fold volumn of clean water for 12 h.

Fine-needle aspiration (FNA) of lymph nodes has been regarded as a useful method in the diagnosis of lymphadenopathy. However, this procedure has been shown to be of limited value in the diagnosis of low or intermediate grade malignant lymphomas in some studies. Immunophenotyping is an essential adjunct to cytomorphology for the diagnosis of lymphoma by FNA. Immunophenotyping using flow cytometry (FCM) is rapid, objective and reliable. Using FCM, multiparametric analysis of 33 FNA materials from lymph nodes was performed and profiles of surface markers of lymphoid cells were assessed. In reactive hyperplasia, patterns of cell surface markers were quite variable, but disclosed polyclonality. Most of the B-cell lymphomas showed immunophenotypes for B-cell lineages with their kappa: lambda or lambda: kappa ratio being over 3:1. In T-cell lymphomas, T-cell surface markers were predominantly expressed as well. In conclusion, our results suggest that immunophenotyping of lymph node aspirates is a valuable diagnostic adjunct for lymphoproliferative disorders, particularly in B-cell lymphomas because immunophenotyping can be easily and adequately performed by FCM.

OBJECTIVETo investigate the clinical application of laparoscopy-assisted subtotal colectomy with transanal specimen extraction for slow transit constipation(STC).

METHODSRetrospective analysis was performed on the clinical data of 8 cases with STC undergoing the procedure mentioned above from February to November 2013. Pre-and post-operative constipation was assessed using Wexner Constipation and Incontinence Scales, and quality of life was assessed using Gastrointestinal Quality of Life Index.

RESULTSAll the operations were completely successful without postoperative complications, such as intestinal fistula, pelvic infection, anastomotic stricture, intestinal obstruction. The Operative time was (287.6 ± 21.5) min, blood loss was (109.7 ± 41.1) ml, time to first flatus was (2.5 ± 0.9) d. The proportion of postoperative constipation symptom index improvement was(77.6 ± 8.3)%. Postoperative quality of life score was 97.3 ± 15.7, significantly higher than that before operation(P<0.05). Postoperative Wexner constipation score was 8.8 ± 3.7, significantly lower than that before operation.

CONCLUSIONLaparoscopy-assisted subtotal colectomy with transanal specimen extraction in the treatment of STC has good short-term efficacy with obvious improvement in quality of life.

Pulmonary hamartomas are uncommon benign tumors, usually discovered radiologically as a solitary coin lesion in asymptomatic individual. The approach to the patient with a peripheral lung nodule has changed with the increasing acceptance of fine needle aspiration cytology(FNAC) as a rapid, safe, inexpensive, and highly accurate diagnostic tool. However, a few reports describing the FNAC findings of pulmonary hamartoma have appeared in the cytologic literature and the experience of FNAC is limited. We reviewed all 9 cases of pulmonary hamartoma with histologic confirmation after FNAC seen at Asan Medical Center since 1995 to evaluate cytologic findings and to determine the value of FNAC in identifying that lesion. Originally, seven of nine patients were diagnosed as pulmonary hamartoma, while two patients were diagnosed as inflammatory lesion and adenocarcinoma of each. On review, eight of nine patients were considered as diagnostic of pulmonary hamartoma. The diagnostic findings in FNAC of pulmonary hamartoma were the presence of fibrillary myxoid tissue with spindle cells as well as hyaline cartilage.

Aim To investigate the effectiveness and safety of alfentanil in general anesthesia.Methods In this study, a multicenter randomized double-blind con¬trolled study was conducted.A total of 352 subjects were selected and randomly assigned to fentanyl group (group A, n =176) and alfentanil group (group 15, n = 176).Anesthesia induction: intravenous midazolam 0.03 mg • kg-1 + fentanyl 25 p.g • kg"'(group A) or alfentanil 4 p,g • kg-1 ( group 15) + propofol 2 mg • kg"1 + rocuronium 0.8 mg • kg"1.Sevoflurane + fent¬anyl ( group A ) or alfentanil ( group B ) + rocuronium were used for anesthesia.The vital signs of patients re¬covery time and extuhation time, anesthesia-related complications and the use of related remedial drugs during anesthesia induction and maintenance were compared between the two groups.Results During the induction and maintenance period of anesthesia, alfentanil and fentanyl could equally effectively inhibit the stress response induced by endotracheal intubation and surgical stimulation.Alfentanil also showed more effective inhibition on stress response induced by endo¬tracheal intubation and surgical stimulation than that of fentanyl ( P < 0.05 ) .However, there was no signifi¬cant difference in the incidence of intraoperative hypo¬tension and hypertension and the time of anesthesia re¬covery and extubation between the two groups.Conclu¬sions Both alfentanil and fentanyl can effectively in¬hibit the stress response induced by surgical stimulation and could be safely used in general anesthesia in sur¬gery.Alfentanil has more advantages in maintaining the stability of blood pressure and heart rate during an¬esthesia induction and maintenance.

Objective: To estimate the health-adjusted life expectancy (HALE) of adults in Zhejiang province and evaluate the health status of the adults. Methods: This study was based on the mortality data collected from Zhejiang Chronic Disease Surveillance Information and Management System, and mortality rates from the underreporting survey and self-reported health data in 2016. Hierarchical Ordered Probit (HOPIT) model was used to estimate the severity-weighted prevalence of disability. Sullivan's method was used to calculate the HALE. Results: After adjustment by HOPIT model, the severity-weighted prevalence of disability increased significantly with age (χ(2)=5 795.81,P<0.001), and it was higher in females than in males (χ(2)=5 353.27, P<0.001). The life expectancy and self-evaluated HALE were 59.08 years and 48.68 years, respectively, in those aged ≥20 years, the difference was 10.40 years due to disability. The proportion of HALE loss due to disability in the total life expectancy was 17.61%, and it increased with age. HALE was higher in males than in females (49.21 years vs. 48.14 years), and in urban residents than in rural residents (49.92 years vs. 47.43 years). Conclusion: The proportion of loss of HALE in the total life expectancy in adults was high in Zhejiang, and it higher in males than in females, in urban residents than rural residents. Programs on improving health care in women and rural residents should be promoted.

Sclerosing mucoepidermoid carcinoma with eosinophilia (SMECE) is a recently recognized malignant neoplasm of the thyroid gland. About 14 cases of SMECE have been reported and this is the first reported case in Korea. A 57-year-old woman presented with right neck mass for 20 years. Total thyroidectomy was performed under the impression of thyroid carcinoma. The resected thyroid gland showed a poorly circumscribed hard mass. Histologically, the tumor consisted of solid nests of large atypical cells with dense fibrous stroma. The tumor cells showed squamoid appearance with abundant eosinophilic cytoplasm. There were also rare mucin-containing cells within the nests. Within the hyalinized stroma, numerous eosinophils were found. The surrounding thyroid parenchyma displayed Hashimoto's thyroiditis. There was metastasis in a regional lymph node. Two years after initial surgery, she underwent a modified radical neck dissection due to recurrent neck mass. After the radiation therapy for eight weeks, laryngectomy and esophagectomy were performed due to a recurrent carcinoma in the esophageal wall. We report an additional case of SMECE, with metastasis to regional lymph nodes and esophagus. The tumor appears to be more aggressive than previously reported and a correct diagnosis can be rendered by just examining the metastatic lesions.

PURPOSE: The loss of p16 protein has been frequently detected in breast carcinoma, but genetic alterations are infrequent. CpG islands of methylation within the p16 promotor have been identified as a mechanism that inactivates the p16 expression. The object of this study is to investigate the relationship between the loss of p16 protein and methylation as a molecular mechanism of the p16 gene inactivation in mammary tumorigenesis. METHODS : We performed an immunohistochemical assay of p16 protein in 70 cases of mammary carcinomas, and we tested for DNA methylation of p16 using methylation-specific PCR, and we then analyzed its correlation with the histopathologic variables. RESULTS : Among the 70 cases, the p16 expression was lost in 32 cases (45.7%), which was not significantly correlated with the pathologic variables. Twenty-three cases with and 27 cases without loss of p16 expression were tested for DNA methylation of p16. Twenty-one of the 23 interpretable cases with loss of p16 expression (91%) showed hypermethylation on p16, but there was no hypermethylation in any of the cases that were without the loss of the p16 expression. CONCLUSION: These findings suggest that the loss of the p16 expression is one of the common abnormalities observed in breast carcinoma and that methylation on the 5'CpG island of the p16 promoter is a major process for p16 ink4 inactivation in breast carcinoma.

OBJECTIVETo evaluate and compare the value of dynamic multiple pelvic angiography and pelvic four-contrast defecography in the diagnosis of functional defecation disorder.

METHODSFrom September 2014 to July 2015, a prospective controlled trial was carried out in Chengdu Anorectal Hospital. A total of 32 patients met the inclusion criteria of functional defecation disorder simultaneously underwent pelvic four-contrast defecography and dynamic multiple pelvic angiography. The diagnostic results of these two methods were compared.

RESULTSThe absolute values of anorectal angle and level of perineum, peritoneum and bladder from rest to defecation were (29.6±13.6)°, (26.2±14.2) mm, (55.5±25.6) mm and (28.9±16.5) mm in dynamic multiple pelvic angiography, and (24.6±5.8)° (18.7±10.6) mm, (34.5±18.4) mm and (19.2±11.8) mm in pelvic four-contrast defecography respectively, whose differences were statistically significant (P = 0.026, 0.022, 0.000, 0.011 respectively). The diagnostic rate of pelvic peritoneal hernia was 93.8%(30/32) and 68.8%(22/32) in dynamic multiple pelvic angiography and pelvic four-contrast defecography respectively with significant difference(P=0.011).

CONCLUSIONDynamic multiple pelvic angiography has significant advantage in the diagnosis of pelvic peritoneal hernia, and can provide a more objective basis for the diagnosis of functional defecation disorder.
