Purpose To study the clinicopathologic features and differential diagnosis of primary mucosal melanoma of the nasal cavity (PMMNC).Methods 17 cases of PMMNC diagnosed from January 2003 to September 2016 were studied by clinical pathological analysis and immunohistochemical staining,and relevant literatures were reviewed.Results 73％ of the PMMNC was characterized by unilateral nasal congestion and intermittent epistaxis and 61％ of the PMMNC occurred in the nasal septum and nasal side wall.Microscopically,the organizational structure and morphology were complex and diverse,which had several cell types including epithelioid cell type (6cases,35.3％),spindle cell type (3 cases,17.6％) and snall cell type (5 cases,29.4％),the other 3 cases (17.6％)were mixed cell type.Mitotic activity and tumor necrosis were more likely to be seen in PMMNC,among other clinicopathological features with a small amount of fibrous stroma and melanoma and rich blood vessels.The immunohistochemical study showed that the positive rate of S-100 and HMB-45 were both 93.8％(15 cases) and those of Melan-A and vimentin were both 87.5％ (14 cases),while CK and EMA were both negative (16 cases).Conclusion PMMNC is a rare disease and the phenotype of S-100,HMB-45,Melan-A and vimentin are useful for diagnosis of PMMNC.

AIMTo search for flavonoids which possess stronger vasorelaxation action.

METHODSFour quercetin glycosides (1a - d) were synthesized from quercetin in three steps i. e. selective protection of quercetin, condensation with corresponding acetyiglycosyl bromide, and then removal of the protecting group; Six flavone compounds (2a - f) were prepared from phloroglucinol according to the conventional methods; The structures of synthetic compounds were confirmed by IR, 1H NMR, 13C NMR and MS. Vasorelaxation action of ten synthetic quercetin derivatives (or analogues) and four natural flavonoids compounds were examined on the isolated rat thoracic aorta rings; Comparative octanol-water partition coefficients (logP) were measured using a reversed-phase HPLC method.

RESULTSMost of the tested flavonoids showed concentration dependent relaxation effects against PE-induced contractions of rat aortic rings. These compounds had stronger action with the augment of logP values.

CONCLUSIONCompound 3-bromo-5 ,7-dihydroxyflavone (2d) was identified to have the most potent vasodilating action. These compounds exert vasodilating effects that are related to the logP values. A structure-activity relationship of flavonoids was suggested.

Uridine diphosphate (UDP)-GalNAc : polypeptide N-acetylgalactosaminyltransfemse (ppGalNAcT) catalyzes the initial step in mucin type O-glycosylation in the Golgi apparatus. Here generation and characterization of a polyclonal antibody to human ppGalNAcT2 were described. The subcellular location of ppGalNAeT2 in SGC7901 cell line was investigated using Western blot analysis of fractionated cell extracts and confocal microscopy with this antibody and two Golgi markers: Golgi SNARE (soluble N-ethylmalemide-sensifive factor attachment protein receptor) of 28 ku (GS28) and trans-Golgi network (TGN) 38, markers for the c/s- and trans-Golgi apparatus, respectively. Morphometric analyses indicated that ～60% of the ppGalNAcT2 signal colocalized with the GS28, while～36% of the c/s-Golgi marker colocalized with the ppGalNAeT2. Approximately 34% of the ppGalNAcT2 signal colocalized with the TGN38, whereas 38% of the trans-Golgi marker colocalized with the ppGalNAcT2. The results provide unequivocal evidence for the location ofppGalNAcT2 within the Golgi apparatus, and further highlight the importance of this organelle in the initiation of O-linked glycosylation.

Objective: To analyze the information of patients with acute myocardial infarction (AMI) in a single center during last 6 years, and to distinguish the clinical differences of patients between TakoSTubo cardiomyopathy (TTC) and ST-segment elevation myocardial infarction (STEMI). Methods: A total of 1042 consecutive patients with primarily diagnosed acute anterior ST-segment elevation (STEMI) admitted in our hospital from 2008-01 to 2014-04 were retrospectively enrolled. The relevant patients were studied in 2 groups:TTC group, the patients with coronary angiography (CAG) and the contrast study of left ventricle corrected TTC diagnosis, n=10, and STEMI group, the patients received CAG within 6 hours of on set with conifrmed left anterior descending singlevessel disease at the same period of time as TTC patients,n=32. The basic clinical characteristics, levels of blood lipids, MI related biomarkers, the incidence rate of pathological Q wave, QTc interval and negative T wave in 12-lead ECG were compared between 2 groups. Results: The percentage of corrected TTC diagnosis in patients with primarily diagnosed STEMI was 1.06%. The female gender in TTC group and STEMI group was 100% vs 9%,P<0.01, TTC group had more patients with stress history before on set than that in STEMI group (70% vs 22%,P=0.02), lower levels of MI related biomarkers as CK (486 ± 249) U/L vs (716 ± 132) U/L, CK-MB (13.5 ± 17.1) mg/L vs (47.5 ± 21.9) mg/L, cTnI (22.8 ± 16.3) ng/mL vs (56.4 ± 24.0) ng/mL, allP<0.01. The age of morbidity, the ratios of hypertension, diabetes mellitus and blood lipids were similar between 2 groups. The frequency of abnormal Q-wave in ECG was similar between 2 groups, while the QTc interval was different in TTC group and STEMI group (630 ± 117) ms vs (540 ± 62) ms,P=0.001, the negative T waves in ECG leads II, III, aVF, aVR and V6 were as (100.00% vs 3.13%), (60.00% vs 6.25%), (90.00% vs 3.13%), (100.00% vs 21.88%), (100.00% vs 46.88%), allP<0.05. Conclusion: TTC patients with the main presentation as ST-segment elevation are usually having emotional or physical stress before on set, with obviously prolonged QTc interval and more frequency of negative T waves in ECG.

Objective To determine the effectiveness of preoperative sedation with rectal midazolam and atropine alone or combined with ketamine in infants and young children.Methods One-hundred and six ASA Ⅰ or Ⅱ infants and young children aged 2 months-2 years scheduled for elective general surgical operation were studied in a double blind fashion.The patients were randomly divided into 3 groups:group M received rectal atropine 0.02 mg?kg~(-1) and midazolam 0.5 mg?kg~(-1)(n=39);group MK and MKK received rectal atropine 0.02 mg?kg~(-1), midazolam 0.5 mg?kg~(-1) and ketamine 4 mg?kg~(-1)(MK,n=34)or 8 mg?kg~(-1)(MKK,n=33).The patients were transferred from the ward to the operating room(OR)30 min after rectal administration.Depth of sedation was evaluated before and 15 min after rectal administration; when the patients were separated from their parents and on arrival in OR using De Jong's sedation score system.SpO_2 and HR were monitored in OR.Results The patients were better sedated in group MK and MKK than in group M after rectal administration.Significantly more patients were asleep on seperation from their parents and on arrival in OR in group MK and MKK than in group M. Significantly more patients were calm and not crying at venepuncture in group MKK(63%)and group MK(32%) than in group M(18%).Conclusion Rectal midazolam combined with ketamine and atropine results in better preoperative sedation than rectal midazolam alone in infants and young children.

Objective To discuss the risks of hypertension development with relation to the level of lipid variables among populations who had normal blood pressure at baseline study. Methods In April 2000, under the support of project "prevention of metabolic syndrome and multi-metabolic disorders in Jiangsu province", a cohort study was performed to obtain the baseline data among 8685 persons from age 34 to 74. In June of 2006, a follow-up investigation was carried out among those who had been in the study for 5 years after the baseline study started. 2603 persons who met the selection criteria and showed normal blood pressure during baseline study, were recruited in this investigation. The interval from the baseline to the follow-up studies was 6.38 years on average. Relationship between the risk of developing hypertension and the baseline level of lipid variables were analyzed. Results Relations between baseline lipid levels and the incidence of hypertension during the follow-up was discovered. In gender and age adjusted model, the lipid variables were all associated with hypertension(Wend test, P<0.01). In multivariable-adjusted model, HDL-C [aRR=0.71 (95%CI: 0.61-0.99)], non-HDL-C [αRR=1.28 (95%CI: 1.14-1.83)], TC/HDL-C ratio[aRR=1.41 (95%CI: 1.25-2.03)] and TG [αRR=1.49(95%CI: 1.30-2.13)] were again associated with hypertension (trend test, P<0.05). Even the αRR was much weakened after the baseline SBP, DBP were adjusted with Cox model, the significant relation of hypertension to HDL-C, TC/HDL-C ratio and TG still existed. Excluding the two factors of obesity (BMI≥28) and diabetes which had been recognized in marked linking with hypertension, lipid variables were still associated with hypertension. Conclusion Dyslipidemia might occur before being hypertensive. Hypertension was associated with HDL-C, TC/HDL-C and TG or even exclusion of obesity, diabetes and factors of smoking and drinking or baseline level of SBP, DBP were adjusted.

OBJECTIVETo study the clinical characteristics and the treatment of periorbital injuries.

METHODS61 cases were treated, including 30 cases orbitozygomatic fracture, 6 cases of frontal-orbital fracture, 8 cases of naso-ethmoid-orbital fracture, 7 cases of blow -out fracture and 10 cases of complicated fracture. The patients were diagnosed after physical examination and other examination, like CT. Through bicoronal or local mini incision at the end of eyebrow, combined with subciliary incision and local wound approach, the fractured sites were exposed completely. Then the fractured fragments were repositioned and fixed rigidly. The orbital wall was reconstructed with titanium net and Medpor.

RESULTSThe wounds healed primarily. Good cosmetic and functional results achieved in most of the patients. 4 cases underwent second-stage ophthalmectomy. 2 patients had diplopia after operation, but improved gradually. 3 cases of blepharoptosis needed further treatment.

CONCLUSIONSEarly diagnosis and treatment is very important for periorbital injuries. Fracture reposition and orbital wall reconstruction should he performed at early period.

OBJECTIVETo explore the clinical efficacy of the arthroscopic Mender II stapler for the treatment of patients with meniscus anterior horn injury needing meniscal suture repair.

METHODSAmong 47 patients with meniscus anterior horn injury, 29 patients were male and 18 patients were female, ranging in age from 12 to 31 years old, with a mean age of (20.53± 4.12) years old. The duration of disease ranged from 3 to 35 days, and the average duration was (12.43±5.74) days. The Mender II stapler was used to carry out arthroscopic suture from outside to inside. The Lysholm knee scoring system was used to evaluate and analyze preoperative and postoperative symptoms, such as pain, limping embolism and so on.

RESULTSForty-six patients were followed up, and the duration ranged from 12 to 48 months, with a mean of (20.53±4.12) years. The incision healed at the first stage without important vessels and nerves injuries. The symptoms of the locked knee joint disappeared, and symptoms such as pain, limp, swelling and limitation of activity improved. The Lysholm score increased from preoperative 52.33±7.31 to postoperative 86.74±6.92.

CONCLUSIONUsing Mender II stapler to treat patients with meniscus anterior horn injury who were treated with arthroscopic suture from outside to inside is effective to improve symptoms, and to obtain good short-term results.
