Objective To analyze the clinical features of rectal and perianal inflammatory myofibroblastic tumor and evaluate its diagnosis and treatment.Method Clinicopathological data of 3 cases diagnosed as inflammatory myofibroblastic tumor from January,2005 to June,2011 were retrospectively reviewed.Results Inflammatory myofibroblastic tumor presents as infiltrative growth mass with rich vascularization on CT or MRI,and is difficult to distinguish from hemangioma and other rectal tumors.Preoperative biopsy usually fails to ascertain the entity of mass,and pathological examination of the whole resected specimen with immunohistochemical staining is needed to make final diagnosis.All 3 cases underwent sphincter preserving surgery.One case received a second radical operation 16 months after primary resection because of local recurrence.All patients are followed up to now,with a survival time of 67 months,55 months,and 35 months respectively.Conclusions Rectal and perianal inflammatory myofibroblastic tumor is difficult to diagnose on preoperative imaging examinations or biopsy.Immunohistochemical staining is needed to make final diagnosis.Sphincter preserving surgery with complete tumor removal could achieve long term survival.

Aim To investigate the arrest effect of diallyl disulfide(DADS) in the cell cycle of human nasopharyngeal carcinoma SW480 cell line and its molecular mechanism.Mothdes The growth inhibition effect of DADS of different concentrations on SW480 cell line was measured by MTT assay and cell counting.Phase distribution of cell cycle was analyzed by flow cytometry.Expression of Ubiquitin and FKBP was determined by Western blot.Results The MTT assay showed that DADS inhibited growth of SW480 cells significantly in a dose-dependent manner.Adding 25,35,50 and 70 mg?L-1 DADS for 48 hours,SW480 cell growth was suppressed by 18.67%,33.02%,49.12% and 66.86%,respectively.There were significant differences between the treated and controlled cases(P

Background and objective Apolipoprotein E is a constituent of lipoproteins with considerable variation due to cysteine-arginine exchanges. We investigated the relationship between apo E gene polymorphism and the occurrence of coronary artery disease(CAD) in the older population of northern China. Methods The distribution of the HhaI polymorphisms of the apolipoprotein E gene was determined among 55 patients with CAD (CAD group), which was compared with that of 36 elderly subjects without CAD(control group). Results Genotype distributions at both sites (apo E gene 112-bp and 158-bp sites ) were different between the CAD and control groups. The CAD group had lower apolipoprotein Eε2frequencies than the control group (P＜0.05). Conclusion Individuals with apolipoprotein Eε2are likely to have a reduced risk of developing coronary artery disease as demonstrated by elderly subjects in Northern China.

Objective: To investigate the incidence of adverse event following immunization (AEFI) with 13-valent pneumococcal polysaccharide conjugate vaccine (PCV13) in Jiaxing City, Zhejiang Province, so as to provide insights into safety monitoring and evaluation of PCV13. Methods: Surveillance data of AEFI with PCV13 in Jiaxing City from 2020 to 2022 were collected from the AEFI Monitoring Information Management System of the Immunization Planning System of Chinese Disease Prevention and Control Information System, including demographic information, vaccination time, time of AEFI occurrence and clinical symptoms, and the reported incidence, population and district distribution, and clinical symptoms of AEFI with PCV13 were descriptively analyzed. Results: Totally 455 cases of AEFI with PCV13 were reported in Jiaxing City from 2020 to 2022, with a reported incidence rate of 232.33/105 doses. There were 431, 21 and 3 cases of general, abnormal, coincidence and psychogenic reactions, with reported incidence rates of 220.07/105 doses, 10.72/105 doses and 1.53/105 doses, respectively, and no reports of causal reaction, vaccine quality accident and vaccination accident. The AEFI cases included 258 boys and 197 girls, with a boy/girl ratio of 1.31∶1, and 288 children at ages of less than a year (63.30%). The largest number of AEFI was reported in Haining City (87 cases, 19.12%), and there were 349 AEFI cases (76.70%) within 24 hours following vaccination. The clinical symptoms mainly included redness and swelling, fever and induration, with reported incidence rates of 132.76/105 doses (260 cases), 109.27/105 doses (214 cases), and 55.66/105 doses (109 cases), respectively. There were 450 cases cured and 5 cases improved in 455 cases of AEFI. Conclusions General reaction is the predominant AEFI in Jiaxing City from 2020 to 2022, with mild symptoms. Most AEFI occurs within 24 hours following vaccination, and has a good prognosis.

Objective: To observe the effect of moxibustion on the expressions of tumor necrosis factor-α (TNF-α) and nuclear transcription factor kappa B (NF-κB) proteins in ankle joints of rats with rheumatoid arthritis (RA), and to explore the anti-inflammatory mechanism of moxibustion in the treatment of RA.Methods: Adjuvant arthritis (AA) rat models were induced and used as rat models of RA. Rats were randomly divided into a normal group, a model group, a moxibustion group and a saline group. Rats in the normal and model groups were not treated; rats in the moxibustion group accepted treatment by moxibustion at Zusanli (ST 36) and Shenshu (BL 23) after modeling; rats in the saline group were injected with 0.15 mL saline to the bottom of the left hind paw and had no other treatments. Hematoxylin-eosin (HE) staining was used to observe the histopathological changes of rats' ankle joints under light microscope. Immunohistochemistry was used to observe the expressions of TNF-α and NF-κB in ankle joints of rats.Results: Compared with the normal group, the rats' ankle joints in the model group showed disorganization, joint surface defect, and significantly increased mean optical density (MOD) of TNF-α and NF-κB (allP<0.05). After moxibustion treatment, rats in the moxibustion group showed repaired ankle tissues, smooth joint surface without defects, decreased MOD of TNF-α and NF-κB than those in the model group (allP<0.05). Rats in the saline group had no damage to ankle joints, while TNF-α and NF-κB were significantly different from those in the model group (P<0.05).Conclusion: Moxibustion could down-regulate the expressions of NF-κB and TNF-α protein in ankle joints of RA rats, and produce an anti-inflammatory effect to promote tissue repair.

Objective To identify the main etiologies of emergency room (ER) patients with chest pain or equivalent syndrome.Methods This was a prospective and cross-sectinal survey of ER patinets with chest pain or equivalent syndrome in 17 medical centre in Beijing,China from July to August 2009.Data was collected by structured interviews and medical record reviews.The mean follow up period was 30 days.Results A total of 5666 patients were enrolled in the study (2663 males and 3303 females) and the mean age was 58.1 ± 18.4years.Their final diagnoses were:coronary heart disease 1506 ( 27.4％ ),acute heart failure 149 ( 2.6％ ),pericarditis 4 ( 0.1％ ),pulmonary embolism 11 ( 0.2％ ),aortic dissection 8 ( 0.1％ ),acute cerebrovascular disease 431 ( 7.6％ ) and non-cardic chest pain 2538 ( 44.9％ ).Thirty-seven cased died and 275 cases hospitalized again 30 days later,4.9％ patients with cornary heart disease had symptoms at their presentation.Conclusion Special vigilance and thorough coronary artery evaluation are needed for all patients with chest discomfort or respiratory distress in the ER,even for patients without chest pain.

OBJECTIVEBased on the different physiological characteristics of the mastoid skin and soft tissue of Chinese congenital microtia malformation, the Nagata two-stage method was respectively applied for ear reconstruction, and the clinic experience were investigated in this study.

METHODAccording to the mastoid skin and soft tissue difference in the thickness and tightness, 280 patients diagnosed with congenital microtia were divided into four types: thin and tight, thin and loose, thick and tight, thick and loose type. 90 cases of thin and loose type accepted the Nagata method of ear reconstruction surgery.

RESULTSWith average 7.8 months follow up, 84.4% (76/90) cases using Nagata two-stage method were satisfied with the outcome of the reconstructed ear including three dimensional position and subunit appearance. There were no postoperative complication related to chest wall deformity or affected normal physical function.

CONCLUSIONSThe Nagata two-stage method is appropriate management choice for Chinese congenital microtia. Based on the different physiological characteristics of the mastoid skin and soft tissue, the selection of different operational should be beneficial to the ear reconstruction of Chinese congenital microtia malformation.

OBJECTIVE: To analyze the impact of β-tubulin-III (TUBB3), thymidylate synthase (TS) and excision repair cross complementation group 1 (ERCC1) mRNA expression on chemoresponse and clinical outcome of patients with advanced gastric cancer treated with TXT/CDDP/FU (DCF) regimen chemotherapy. METHODS: The study population consisted of 48 patients with advanced gastric cancer. All patients were treated with DCF regimen palliative chemotherapy. The mRNA expressions of TUBB3, TS and ERCC1 of primary tumors were examined by multiplex branched-DNA liquid chip technology. RESULTS: The patients with low TUBB3 mRNA expression had higher response rate to chemotherapy than patients with high TUBB3 expression (P=0.011). There were no significant differences between response rate and TS or ERCC1 expression pattern. Median overall survival (OS) and median time to progression (TTP) were significantly longer in patients with low TUBB3 mRNA expression (P=0.002, P<0.001). TS or ERCC1 expression was not correlated with TTP and OS. In the combined analysis including TUBB3, TS and ERCC1, the patients with 0 or 1 high expression gene had better response rate, TTP and OS than the remaining patients (all P<0.001). Multivariate analysis revealed that ECOG (Eastern Cooperative Oncology Group)≥2 (HR=2.42, P=0.009) and TUBB3 (HR=2.34, P=0.036) mRNA expression significantly impacted on OS. CONCLUSION High TUBB3 mRNA expression is correlated with resistance to DCF regimen chemotherapy. TUBB3 might be a predictive and prognostic factor in patients with advanced gastric cancer treated with TXT-based chemotherapy. The combined evaluation of TUBB3, TS and ERCC1 expression can promote the individual treatment in advanced gastric cancer.

OBJECTIVETo investigate the relationship among -75 bp/+83 bp polymorphism in apolipoprotein A1 (apo A1) gene, lipids levels and the occurrence of coronary atherosclerosis disease (CAD).

METHODSWe determined distributions of two MspI polymorphisms of the apo A1 gene at -75 bp and +83 bp, and blood lipids levels among 137 Chinese patients (92 with CAD and 45 in the control group) in relation to circulating lipids and coronary angiography.

RESULTSThe demographic information for 137 subjects showed that subjects with CAD tended to have more unfavorable lipoprotein variables. Genotype distributions at both sites were different between the CAD and control groups. Furthermore, the control group had higher M1-/M2- frequencies than the CAD group (M1: P < 0.005; M2: P < 0.05) and the "M1-" (A) and "M2-" alleles were associated with increased high-density lipoprotein cholesterol (HDL-C) (M1-: P < 0.0001; M2-: P < 0.05) and apo A1 (M1-: P < 0.0001; M2-: P < 0.05) levels. "M1-" and "M2-" were significantly negatively correlated with CAD (P < 0.01 and P < 0.05, respectively).

CONCLUSIONSOur results suggest that changes from G to A at the -75 bp site and from C to T or G to A at the +83 bp site do increase circulating levels of apo A1 and HDL-C. And those individuals with these changes are likely to have a lower risk of developing CAD.

OBJECTIVETo investigate whether patients, who are at risk of major acute coronary events, are safe to undergo and benefit from early intervention after using simvastatin.

METHODSThe study was a randomized, open, two-dosage-controlled trial to evaluate the safety and benefits of simvastatin administered to 197 patients (10 mg group, n = 98 and 20 mg group, n = 99), within 48 hours of hospitalization for a diagnosis of unstable angina or acute myocardial infarction (MI), with total cholesterol (TC) >/= 180 mg/dL or low-density lipoprotein cholesterol (LDL-C) >/= 100 mg/dL. Lipid levels were measured immediately, followed by the 3rd, 6th and 12th month after admission and all adverse events were recorded during follow-up.

RESULTSTC levels fell by 10.15% and 14.52% in the 10 mg and 20 mg groups (P < 0.05), and LDL-C levels fell 13.87% and 19.38% in the 10 mg and 20 mg groups, respectively (P < 0.01), 12 months after using simvastatin. The rates of achieving target TC reached 26.3% and 36.5% in the 10 mg and 20 mg groups (P < 0.01), and that of LDL-C reached 28.2% and 40.3% in the 10 mg and 20 mg groups, respectively (P < 0.01). There were higher rates of MI and re-hospitalization resulting from angina pectoris and revascularization in the 10 mg group compared with the 20 mg group.

CONCLUSIONSThe results suggest that early intervention with the HMG-CoA reductase inhibitor, simvastatin, in acute coronary syndromes is possible and safe. It also indicates that the clinical dosage of simvastatin are relatively smaller than that for satisfactory lipid control in patients with acute coronary syndromes.
