Mycoplasma pneumonia (MP) is one of common pathogens of community-acquired pneumonia in children. In recent years, the incidence of MP pneumonia (MPP) shows a trend of increasing. The report of severe refractory MPP was more and more. Glucocorticoids has anti-inlfammatory, anti-allergic and restraining immune response pharmacological effects and is the most effective anti-inlfammatory drug currently. In this paper, pathogenesis of the lower respiratory infection by MP and the therapeutic effects of glucocorticoid were reviewed.

Objective To study the effects of mifepristone on the expression of estrogen receptor(ER)? and progesterone receptor(PR) in the endometrium of patients with adenomyosis in different menstrual cycles. Methods Forty-seven patients with adenomyosis and 15 normal subjects were divided into 3 groups: mifepristone group(n=24),non-drug group(n=23) and control group(n=15).The expression of ER? and PR in eutopic,ectopic and normal endometrium in proliferative phase and secretory phase were detected by immunohistochemistry. Results In non-drug group,the expression of ER? and PR in ectopic endometrial glandular and stromal cells was significantly lower than that in eutopic and normal endometrium(P0.05).The expression of ER? and PR in both ectopic and eutopic endometrial glandular and stromal cells in mifepristone group was lower than that in the non-drug group(P

The effect of micronutrients on pressure ulcer was reviewed.Nutritional treatment is helpful to prevent and cure the pressure ulcer.Especially micronutrients should be paid more attention to.

Objective To observe the effect of hybrid renal replacement therapy (sustained lowefficiency hemodiafiltration) in recipients with delayed graft function (DGF) after kidney transplantation.Methods In 33 kidney transplant patients with DGF,there were 15 cases subject to sustained low-efficiency hemodiafiltration (SLEDF group),18 cases subject to hemodialysis (HD group).The renal function was tested,and the expression levels of complements C3,C4,and CRP,IL-1β,IL-6,TNF-α were detected before and after therapy.Results In SLEDF group,the renal function recovered in (29 ± 13) days after therapy,and in (47 ± 21) days in HD group.After therapy,the BUN and Scr in both two groups were lower than before (P＜0.01).After therapy,the levels of IL-1β,IL-6 and TNF-α were also lower than before in two groups,and the levels were lower in SLEDF group than in HD group (P＜0.05).The levels of complements C3,C4,and CRP in two groups were decreased after therapy,but there was no statistically significant difference (P＞0.05).Conclusion SLEDF can decrease the level of SCr,BUN and some cytokines in recipients effectively,and It's helpful to recovery of the renal function.SLEDF can be used by DGF recipients in transit time.

Objective To analyze the diagnosis and treatment of iliac pseudoaneurysms following renal transplantation.Method The data of two patients with pseudoaneurysm who underwent kidney transplantation were retrospective analysied.Result One case with pseudoaneurysm received transplant nephrectomy,and pathological examination diagnosed mucoraceae infection; the other patient received endovascular treatment and amphotericin B therapy,endly died of hemorrhagic shock.Conclusion The development of pseudoaneurysms at the kidney transplantation recipients with the same donor results in high rates of mucormycosis.They should take anti-fungus therapy and operation as early as possible.

Objective To study the therapeutic effect of adjuvant chemotherapy and radiotherapy after operation in patients with mucoepidermoid carcinoma of parotid gland,and to screen the indicators ralated to the prognosis of tumor.Methods Eighty patients with mucoepidermoid carcinoma of parotid gland in First People′Hospital of Yibin of Sichuan Province from January 2005 to December 2009 were analysed retrospectively in our research.We studied the survival of patients who were treated wtih simple operation(30 cases)or postoperative adjuvant therapy(50 cases).Then we further analyzed the relationships between the prognosis of the patients and some variables (age,gender,smoking,alcohol drinking,lymph node metastasis,distant organ metastasis,treat-ment method,differentiation degree and T grading).Results Kaplan-Meier survival curves showed that patients with postoperative adjuvant therapy had longer PFS and OS than those without adjuvant therapy (94.4 months vs 69.3 months;114.9 months vs 96.7 months),with statistical significance (χ2 =11 .246,P =0.001 ;χ2 =15.803,P =0.001 ).COX univariate analysis showed that gender (χ2 =22.346,P =0.000),smoking (χ2 =7.891 ,P =0.041 ),lymph node metastasis (χ2 =12.371 ,P =0.005),distant organ metastasis (χ2 =9.81 3, P =0.002),treatment method (χ2 =25.261 ,P =0.000),differentiation degree (χ2 =4.361 ,P =0.006)and T grading (χ2 =5.336,P =0.01 4)were related to the PFS of patients.COX multivariate analysis showed that lymph node metastasis (χ2 =11 .003,RR =2.827,95%CI:1 .965-3.851 ,P =0.011 ),distant organ metastasis (χ2 =7.611 ,RR =0.472,95%CI:0.240-0.775,P =0.016),treatment method (χ2 =24.542,RR =5.390, 95%CI:3.585-9.602,P =0.000),degree of differentiation (χ2 =3.221 ,RR =2.1 1 8,95%CI:1 .845-4.719, P =0.009)and T grading (χ2 =4.336,RR =0.804,95%CI:0.681 -0.916,P =0.024)were related to the PFS of patients.COX univariate analysis showed that smoking (χ2 =4.551 ,P =0.008),alcohol drinking (χ2 =11 .742,P =0.048),lymph node metastasis (χ2 =14.886,P =0.009),distant organ metastasis (χ2 =6.71 3, P =0.005),treatment method (χ2 =22.411 ,P =0.000),degree of differentiation (χ2 =8.1 16,P =0.012)and T grading (χ2 =14.443,P =0.035)were related to the OS of patients.COX multivariate analysis showed that lymph node metastasis (χ2 =11 .711 ,RR =2.985,95%CI:1 .521 -3.999,P =0.005),distant organ metastasis (χ2 =5.390,RR =0.400,95%CI:0.201 -0.793,P =0.009),treatment method (χ2 =19.327,RR =5.086, 95%CI:3.241 -8.006,P =0.000),degree of differentiation (χ2 =7.084,RR =2.301 ,95%CI:1 .908-4.503, P =0.001 )and T grading (χ2 =1 3.229,RR =0.561 ,95%CI:0.348-0.867,P =0.040)were related to the OS of patients.Conclusion Adjuvant radiation and chemotherapy can obviously prolong the PFS and OS for the patients with mucoepidermoid carcinoma of parotid gland.Lymph node metastasis,distant organ metastasis,treat-ment method,differentiation degree and T grading can greatly influence the prognosis of patients with mucoepider-moid carcinoma of parotid gland,which can be used as independent prognostic indicators for the patients with mucoepidermoid carcinoma of parotid gland.

Objective: To study on the changes of shedding particles, drug loading and release of Chuanping Sustained-release Tablets (CST) which were made by the different sustained-release excipients in vitro, so as to elucidate the mechanism about balanced release of multi-marker components on Chinese materia medica compound sustained-release preparation. Methods: Using Chuanping Prescription (Ephedra Herba and Datura Flos) as model drug, improved Peach Gum and HPMC was used as sustained release materials, the release test combinied with underwater video observation were applied to shot external forms at different time point, and the laser particle sizer was applied to determinate particle size, and HPLC was applied to determine the accumulated release rate of the index components (ephedrine, pseudoephedrine, and scopolamine) to calculate the cumulative release curve slope K value, and to evaluate the balance release of the different components. Results: CST which were made by the improved peach gum and HPMC sustained-release excipient, which particles were dropped at 0.5 h after contacting the dissolution medium. At the same time, the particles were obviously shedding with the passage of time. In contrast, CST that was made by the improved peach gum, its balanced release of multi-marker components was better (K of ephedrine was 12.18, K of pseudoephedrine was 12.30, and K of scopolamine was 12.40), and particles dropped faster (it was significantly at 1 h), and particle size was bigger (D50 was 53.37—70.33 μm and D90 was 100.3—196.5 μm), and drug loading was more (ephedrine 30.63%, pseudoephedrine 32.97%, and scopolamine 31.67%), and release time of drug was longer (60—120 min). Conclusion: The shedding particles were important part of balance release of multi-marker components about CST which was made by the improved peach gum sustained-release excipient, and also was the embodiment of the drug release mode of “corrosion-dissolution”.
