Objective: To investigate the relationship between the ac tive granulae in mast cells and infant hemangiomas of parotid gland. Methods: Surgical samples of parotid gland hemangioma were obtained from 40 infants under the age of 6 months and those of normal parotid gland tis sue from 5.The samples were investigated by safranin staining,alcian blue and th ionine staining, and image analysis technique. Results: Th e percentage of thionine positive cells vs tissue area in hemangioma and normal parotid gland tissue was 1.132?0.195 and 0.335?0.122 ( P

Objective To investigate the effect of aprotinin on the inflammation response to reinfusion of shed blood during operation after being aspirated, filtered and washed using cell saver.Methods Twenty-four ASA I - II patients undergoing elective spinal surgery under general anesthesia were randomly divided into 2 groups: aprotinin group ( n = 12) and control group ( n = 12) .The patients were premedicated with intramuscular pentobarbital 0.1 g and atropine 0.5 mg. Anesthesia was induced with propofol 2 mg ? kg -1 , fentanyl 2-4 ?g ? kg-1 and vecuronium 0.1-0.3 mg ? kg-1 and maintained with isoflurane, propofol infusion and intermittent i. v. boluses of fentanyl and vecuronium. The patients were mechanically ventilated after tracheal intubation. In aprotinin group aprotinin 10 ? 105 IU was given before skin incision and another dose of aprotinin 10 ? 105 IU was continuously infused during operation. The blood shed during operation was collected, anticoagulated with heparin, filtered, washed and reinfused using AutoLog cell saver. Blood samples were taken from CVP line before skin incision (T1 , baseline), 30 min after reinfusion of salvaged bloods (T2) and at the end of operation (T3 ) for WBC and neutrophil granulocyte counts and determination of expression of CD11b and CD18 on the surface of neutrophil granulocytes using flow cytometry. Results The two groups were similar with respect to the general condition of the patients, duration of operation and account of shed blood reinfused. (676? 353) ml was reinfused in control group. The expression of CD11b and CD18 on the surface of neutrophil granulocytes increased significantly at T2 and T3 as compared to the baseline at T1 in control group ( P

Objective To investigate the correlation between autophagy related gene(ATG) locus polymorphism and the pulmonary tuberculosis(PTB) susceptibility according to the frequency distribution characteristics of autophagy related gene in the patients with PTB.Methods Eighteen single nucleotide polymorphism (SNP) loci of autophagy related genes in 202 patients with PTB as the case group and 222 healthy controls were genotyped by SequenomMassArray mass spectrometry array technology.The correlation between the each locus genotype and the PTB susceptibility was statistically analyzed.Results In the PTB patients group and healthy control group,after correcting the factors of sex and age,the binary Logistic regression analysis found that the frequency distribution of genotype and allele had statistical difference between rs5973822 and rs807185 sites in ATG4A gene (P＜0.05).The stratified analysis by body mass index (BMI) found that this difference was more significant in the high BMI population,moreover the distribution frequency in the patient group was lower than that in the control group,and the other 16 SNP loci had no statistical difference.Conclusion ATG4A gene rs5973822 and rs807185 loci polymorphism may be negatively correlated with PTB susceptibility,moreover which is more significant in the high BMI group.

Objective: To assess the predictive value of coronary lfow reserve (CFR) for diagnosing coronary stenosis by transthoracic Doppler echocardiography (TTDE) in patients with hypertension.
Methods: A total of 132 patients scheduled for elective coronary angiography (CAG) due to chest pain were enrolled. The patients were divided into 2 groups: Hypertension group,n=95 and Non-hypertension group,n=37. The CRF of left anterior descending coronary artery (LAD) was measured by ATP stress TTDE at 2 days before CAG in all patients and the results were compared between 2 groups. ROC curve was conducted to assess CFR value in diagnosing LAD stenosis which was deifned by LAD luminal diameter stenosis ≥ 70% in relevant patients.
Results: The condition of LAD stenosis was similar between 2 groups (42.1% vs. 35.1%),P>0.05. The CFR value in Hypertension group was lower than that in Non-hypertension group (2.39 ± 0.86) vs. (2.87 ± 1.12),P<0.05. The ROC curve for diagnosing LAD stenosis in all patients were at 0.884 (95% CI 0.83-0.94,P<0.0001), in Hypertension group at 0.874 (95% CI 0.81-0.94,P<0.0001) and in Non-hypertension group at 0.915 (95% CI 0.82-0.98,P<0.0001). With the cut-off point of CFR ≤ 2.2, it had the diagnostic sensitivity, speciifcity and accuracy in all patients were at 80.3%, 83.5% and 80.3%; in Hypertension group were at 77.5%, 80.0% and 78.9%, in Non-hypertension group were at 69.2, 91.7% and 83.8% respectively.
Conclusion: The patients of hypertension combining chest pain had decreased CFR which implied the dysfunction of their microcirculation. CFR had the better diagnostic value for predicting the signiifcant LAD stenosis in such patients.

Objective To investigate the sedative effects and the adverse reactions in the elderly patients received different speed of dexmedetomidine (Dex) intravenous infusion. Methods Eighty elderly cases were randomly divided into four groups. Group D0 was the control group, while the group D1, D2 and D3 were the trial groups. The heart rates, blood pressure, SpO2, Ramsay sedation score and Narcotrend value were recorded. Results The sedation onset time of the D2, D3 group was faster than those in the D0 and D1 groups (P <0.05, respectively), and the duration of sedation in groups D2 and D3 were significantly longer than that in the D0 and D1 groups (P < 0.05). Among the four groups, no significant differences in the incidence of hypotension or bradycardia needed vasopressors or atropine to treat and oxygen saturation were shown (P > 0.05). Conclusion Intravenous infusion of Dex by doses of 0.75 ~ 1.0 μg/(kg·h) during hip surgery in the elderly patients under spinal anesthesia could lead to a safe and effective sedation.

This article was aimed to study the therapeutic effects and anti-inflammatory effects of Chinese and west-ern medicine ointment on fungal infection animals. Guinea pig models which were infected with Trichophyton rubrum or Microsporum lanosum were applied to observe the effects of antifungal infections on She-Zhi Qin-Xian (SZQX) ointment by transdermal administration. The ointment is the combination of miconazole nitrate, snake oil and Sophora flavescens which is traditional Chinese medicine (TCM). Simultaneously, the models of croton oil-induced mouse ear swelling and carrageenan-induced rat paw swelling were established to observe the curative effect of SZQX ointment. The results showed that the SZQX ointment had a protective role on both guinea pig models. The microscopic scale of localized lesions in infected guinea pigs was significantly decreased (P< 0.01). The effect of SZQX ointment was better than the single using of Chinese or western medicine. The SZQX ointment was also able to significantly reduce the croton oil-induced mouse ear swelling and carrageenan-induced rat paw swelling (P< 0.05, or P< 0.01) with distinct anti-inflammatory effect. And the effect of SZQX ointment was superior to the single using of either Chinese or western medicine. It was concluded that the SZQX ointment had significant antifungal infection and anti-inflam-matory effect.
