The definition of refractory Langerhans cells histiocytosis (LCH) is risk organs (bone marrow, liver, spleen)involvement and the first-line treatment failure.It has a very poor prognosis.The survival depends on timely and effective salvage treatment.Currently the treatment for refractory LCH includes isolated 2-chlorodeoxyadenosine, 2-chlorodeoxyadenosine combined with high-dose cytarabine, indomethacin, hematopoietic stem cell transplantation and targeted therapy.In this paper, the advances in treatment of the refractory LCH in children were reviewed.

The effect of macrophage on IL-2 production by tonsillar T cells was investigated. The human tonsillar mononuclear cells were purified by a two-step procedure including depletion of plastic-adherent cel1s and rosetting with SRBC. The purity of Enriched T cel1s (ETC) was 98%. It was found that IL-2 production was greatly decreased in ETC by removing adherent cells and could be completely restored by replacing the adherent cells. The IL-2 production in the same extent was induced in ETC when TPA was substituted for adherent cells and the synergistic effect of TPA and macrophages greatly augmented the IL-2 secretion by ETC. Incubation of ETC with high concentration of PHA or ConA alone resultes in efficient IL-2 production. These results indicated that IL-2 production was macrophage dependent.

Objective:To review methodology of medicine price index methodology and provide methodological implications for empirical researches. Methods:Based on the recent original home and abroad researches, the price index formulas, the medicine product definition, price and quantity units were introduced in this paper together with their merit/demerit and different selections’ measurement bias. Results: The measurement results were significantly different along with selections of the different weighted price index formulas. The medicine product definition and the price/quantity units in the formulas were different as well. By taking into account the new products entry and the ol-der ones exit updating issue, and by considering the products quality changes issue can also have an important empir-ical implication for the price measurement. Conclusions:The medicine price index methods need to be deeply devel-oped and the researchers should devote to further research and perform accurate measurement. In the empirical analy-sis, researchers can use different methods to measure the medicine price index in order to more accurately reflect the medicine price level change.

OBJECTIVE: To explore the relevance between nasal symptoms and laryngopharyngeal reflux disease in patients with allergic rhinitis. METHOD: Thirty patients of laryngopharyngeal reflux disease were diagnosed in ENT outpatient department in our hospital. All patients have symptoms of sneeze, nasal discharge as chief complaint and they responded no effect for other normal treatment for nasal-sinusitis at least three months. Orally before meals, a dose of 5 mg Mosapride citrate each time, three times a day for 7 days. Orally before meals, a dose of 20 mg Esomeprazole each time, two times a. day for 2-3 months. Nasal spray, one spray of azelastine hydrochloride once, two times a day for 2 month. RESULT: Laryngopharyngeal reflux symptom scores at four time points (the first visit, post treatment 15 days, 45 days, 75 days) were analyzed by repeated measures analysis of variance. There is a significant difference in four time points. CONCLUSION Laryngopharyngeal reflux disease has a strong association with allergic rhinitis. Patients who has allergic rhinitis nasal symptoms as chief complaint must be exclude, the laryngopharyngeal reflux disease first.

Objective: To evaluate the rationality of the use of antibiotic prophylaxis in the perioperative period of herniorrhaphy. Methods: Seventy-five cases of herniorrhaphy discharged in March, June and September of 2009 were collected. Parameters including indications, the types of antibacterial drugs, time of administration, solvent choice, usage and dosage, combination, etc, were assessed for the rationality according to the "the guiding principles of clinical use of antibacterial drugs"and other relevant documents. Results: The antibacterial drugs application rate was 100%, while the rationali-ty of the drug selection, the drug administration route, the single dose and the number of dosing, was 70.7%, 100% , 100% and 93.3% respectively. Sixty-two patients(82.7%)were treated with antibacterial drugs at 0.5～2 hours before surgery, and the average time course of the prophylactic use of antibiotics after surgery was 2.3 days. Conclusions: Some problems existed for the use of antibiotic prophylaxis in the perioperative period of herniorrhaphy. Surgeon should ensure the correct use of the antibacterial drugs to make the safety, efficiency, rationality, and economy for the patients.

Objective To evaluate the effect of oral health instructions in nursing of marsupialized jaw cysts. Methods 46 patients with cysts of jaw were divided randomly into two groups (education group and control), 23 in each. In addition of normal nursing processes in both groups, patients in education group were offered more oral health instructions, such as pathogenesis of jaw cysts, mechanism of marsupialization, wear and clean of a cyst plug, and oral hygiene maintenance. 12 months later, compliance, satisfaction, treatment effect and oral hygiene condition of the patients in the two groups were studied and compared. Results 100%of patients in the education group could return to clinical visits on time and 96%of patients did cyst rinsing after every meal, which were significantly higher (χ2=6.9, P<0.05) than in the control (74% and 70% respectively). Patients′satisfaction in the two groups were also significantly different (χ2=9.109,P<0.05). Patients in the education group were much more satisfied with the treatment procedures than control. The treatment effect of the cyst in the education group [good (83%), moderate (17%), not so good (0%)] was significantly (χ2=7.793, P<0.05) better than control (good (43%), moderate (52%), not so good (5%)]. The secondary infection rates in the two groups were similar (χ2=1.022, P>0.05). Oral hygiene condition of patients in the education group was better than control in Debris Index (χ2=9.576, P < 0.05) and Plaque Index (χ2=8.212, P < 0.05). Conclusions Oral health instructions played positive role in improving patients′ compliance, degree of satisfaction, treatment effect and oral hygiene condition in patients with jaw cysts.

Objective To investigate the roles of P53/P21 during neuronal differentiation with a differentiated model of PC12 cells. Methods A new cell line PC12(P53/m175) was created by stable transfection of a retrovirus plasmid pBabe-P53/m175, which contains a dominant-negative P53 gene mutant. After NGF treatment, observing with phase-contrast microscopy, flow cytometric analysis and western blotting of P53 and P21 were performed. Results Expression of P53 and P21 was obviously increased in NGF-induced PC12 cells. The appearance of cell cycle G1 phase arrest paralleled the increased expressions of P53 and P21. The level of P21 protein did not change after treatment with NGF in PC12(P53/m175) cells and the extent of G1 phase arrest markedly decreased. However, we did find the normal neurite outgrowth in NGF-treated PC12(P53/m175) cells. Conclusion NGF-induced an increased protein levels of P53 and its transcriptional element, P21 is essential for cell cycle G1 phase arrest, but does not necessarily correlate with the neurite outgrowth of PC12 cells.
