OBJECTIVEThis study aimed to conduct a preliminary study on the possible role and significance of interleukin (IL)-12 and IL-27 in the pathogeneses of oral lichen planus (OLP).

METHODSThirty cases of patients with OLP (fifteen cases of reticular OLP and fifteen cases of erosive OLP) were enrolled in this study, and twenty cases of healthy people served as controls. Lymphocyte subsets CD3+, CD4+, CD8+, CD19+, and CD16+56 [natural killer cell (NK)] were tested using flow cytometry, and humoral immunity [immunoglobulin (Ig)G, IgA, IgM, C3, C4] were examined using nephelometry assays. IL-12 and IL-27 contents in serum of patients with OLP and normal controls were detected through enzyme linked immunosorbent assay. The correlations between the levels of IL-12, IL-27, immune status, and clinical characteristics of patients with OLP were analyzed, respectively.

RESULTSCD3+, CD4+, and CD8+in patients with OLP were markedly lower than the normal value, whereas CD 19+ of OLP in patients was significantly higher than the normal value (P<0.05). IgM inpatients with OLP was increased, whereas C4 was declined (P<0.05). IL-12 and IL-27 levels showed significant upregulation or ULF patients compared with control groups (P<0.05). Meanwhile, positive correlations existed between IL-12 andIL-27 levels in the serum of patients with OLP (r=0.912, P<0.01). No significant correlations of IL-12 and IL-27 epressions with clinical characteristics of OLP were found (P>0.05). Negative correlations of IL-12 and IL-27 levels with CD16+56(NK) cells were observed (r1 = -0.416, P1 = 0.022; r2 = -0.392, P2=0.032, respectively), whereas a positive correlation existed for IgG (r1=0.445, P1=0.014; n=0.549, P2=0.002, respectively).

CONCLUSIONA cellular immune dysfunction mainly dominate in patients with OLP, accompanied by some degree of humoral-immunity-function disorder. The abnormally high expressions of IL-12 and IL-27 are possibly synergized and promoted inflammation development in OLP. Its promotion takes place through the negatie feedback regulation of humoral immune responses, which are involved in the regulation of immune mechanisms of OLP.

Objective To investigate the prognostic value of Fms-like tyrosine kinase3, intenal tandem duplication (FLT3-ITD) detection by DNA extracted from stored bone marrow slides in chemical method. Methods Trace DNA was extracted from 58 bone marrow slides which were stored for 1-5 years below 20 ℃, including 48 patients with de novo acute myeloid leukemia (AML) and 10 controls without hematologic malignancies. Polymerase chain reaction (PCR) was used to detect the FLT3-ITD of these bone marrow slides samples. Results There were 6 patients of FLT3-ITD+ detected in these 48 AML patients (12.5 %, 6/48). No FLT3-ITD was found in 10 healthy controls. AML patients with FLT3-ITD+ had low complete time compared with FLT3-ITD-patients (x2= 7.274, P= 0.007). Splenohepatomegalia and FLT3 mutation were the risk factors affecting AML patients with CR after the first chemotherapy (OR= 7.2, P=0.12; OR=36.3, P=0.10). FLT3-ITD was a risk factor of poor prognosis in patients with newly diagnosed AML (RR=9.088, P= 0.029). Conclusion Extraction of AML bone marrow slides trace DNA by using chemical method can be widely applied in clinic and is a key experimental way to study the molecular biology retrospectively. Furthermore, the detection of FLT3-ITD by trace DNA extracted from stored bone marrow slides can be used to predict the prognosis of AML.

Objective To analyze the prevalent feature and variant tendency of Scrub Typhus in Guangdong Province from 2006 to 2012, and provide a basis of strategy and measure on prevention and protection of Scrub Typhus. Methods Clinical information of all individual cases was gained from China Information System for Disease Control and Prevention. Cochran-Armitage trend χ2 test was used to describe the variance of Scrub Typhus incidence and the clinical cases of 2013 were predicted by autoregressive integrated moving average (ARIMA) model, while descriptive epidemiological analysis was adopted to describe the endemic distribution, seasonal characteristics and population distribution of Scrub Typhus. Results A total of 8 163 Scrub typhus cases were reported in Guangdong Province from 2006 to 2012. Annual mean incidence of the disease was 1.15/100 000 with the incidence showing an upward tendency (χ2 = 3 191.976, P < 0.01). There were 14 dead clinical cases reported with a fatality rate to be 1.72‰(14/8 163). Totally 3 166 people were predicted to infect Scrub Typhus in 2013 by ARIMA model. The disease was prevalent from the end of May to early October and the peak time was in late August (Z = 2 303.71, P < 0.01). The top five cities developed Scrub Typhus were Zhaoqing, Guangzhou, Yunfu, Shaoguan and Qingyuan. Male-female ratio was 1.00 ∶ 1.08 in all reported cases in which 52.78%(4 309/8 163) of them aged from 40 to 65 years old and 59.30%(4 841/8 163) of them were farmers. Conclusions The incidence of Scrub Typhus is rising in Guangdong Province, with the prevalent peak in summer and autumn, and rural populations are at high risk. The most effective preventions are strengthening health education , enhancing individual protection and protecting key populations in special districts.

ObjectiveTo evaluate the safety and superiority of dressings and bandage compression method for patients after percutaneous coronary intervention through femoral artery.MethodsA total of 648 patients who received percutaneous coronary intervention through femoral artery were randomly divided into three groups: the modified group (224 cases), the routine group (213 cases) and the haemostat group (211 cases), they each adopted modified dressings and bandage compression method, the traditional oppression hemostatic method, and arterial oppression with hemostat method.

Objective To explore the role of clinical pharmacists in rational drug use through the pharmacy care of an elderly pneumonia patient with Chlamydia psittaci infection and drug-induced liver injury. Methods The clinical pharmacists participated in the treatment of one patient with Chlamydia psittaci pneumonia and drug-induced liver injury. Based on the results of second-generation gene sequencing, the characteristics of the pathogen were learned by literature search. The clinical pharmacists monitored the patient’s liver and kidney function, provided a new medication treatment plan to Doctors, and performed patient education during the treatment. Results The initial empirical anti-infective treatment with teicoplanin and imipenem-cilastatin was not effective. After the diagnosis of Chlamydia psittaci and Candida albicans infection, the combination of doxycycline with azithromycin and fluconazole was administered. Drug-induced liver injury was found with this treatment. The clinical pharmacist proposed to switch to doxycycline and clarithromycin with co-administration of magnesium isoglycyrrhizinate and polyene phosphatidylcholine to protect the liver. With this new regime, patient's liver function was improved and the infection was under control. Conclusion Individualized pharmaceutical cares provided by clinical pharmacists helped the safe, rational and effective use of medications.

Allotransplantation of peripheral blood-derived hemopoietic stem cells is the best therapy for acute leukemia. With increases of only-child families, sibling donors are decreasing. Moreover, the probability is low and time consuming is long to search a matched hemopoietic stem cell donor from the Chinese Marrow Donor Program. Haploidentical stem cell transplantation would bring a hope for donor resource. However, difficult transplantation and high incidence of graft versus host disease are two risks. Based on modified regimen and cyclosporine A+short-term amethopterin, mycophenolic acid, interleukin-11, anti-lymphocyte immunoglobulin and hemopoietic stem cells mobilized by recombinant human granulocyte colony-stimulating factor can prevent graft versus host disease. This therapy succeeded in two cases with no severe graft versus host disease.

OBJECTIVE:To study curative effect of the combination of cyclosporine A,mycophenolate mofetil,anti-thymocyte globulin,interleukin-11 and short-term methotrexate as acute graft-versus-host disease(aGVHD) prophylaxis on HLA-matched unrelated donor or HLA-mismatched related donor allogenic peripheral blood stem cell transplantation(Allo-PBSCT).METHODS:Thirteen patients with haematological malignancies who underwent HLA-matched unrelated donor or HLA-mismatched related donor Allo-PBSCT with the combination of cyclosporine A as aGVHD prophylaxis at Haikou Municipal People's Hospital from September to November 2008 were selected,including 7 of unrelated donor,3 of haplotype transplantation,and 3 of 1-locus mismatched.The conditioning regimen was performed at 7 days prior to transplantation,with cyclosporine A 5-10 mg/(kg?d),12 hours per time with twice per day.From day 7 prior to transplantation,mycophenolic acid was intravenous drip once per day,then 2.5 mg/(kg?d) antithymocyte globulin at days 5-2 prior to transplantation,1.5 mg/d interleukin 11 was subcutaneous injected at day 2 prior to and 10 days after transplantation,followed by intravenous drip 15 mg/m2 amethopterin at day 1 and 10 mg/m2 at days 3,6,11 after transplantation.The drug doge was reduced and stopped gradually after 3-6 months,which could be prolonged for haplotype grafter.Recombinant human granulocyte colony-stimulating factor was injected subcutaneously at day 3 prior to transplantation,and PBSCT was collected at days 4 and 5 after medication,which was infused to patients with subclavian vein at the same day.In total(7.82-9.11)?108/kg mononuclearcell and(2.9-7.7)?106/kg CD34+ cells were infused.RESULTS:Hematopoiesis was rebuilt in all patients with 46.15%(6/13) aGVHD incidence rate,including 8 %(1/13) of Ⅲ-Ⅳ aGVHD.Up to April of 2009,all patients live and work as normal except one patient who can not visit public places.CONCLUSION:The combination of cyclosporine A,mycophenolate mofetil,anti-thymocyte globulin,interleukin-11 and short-term methotrexate is effective in the prevention of aGVHD.
