ObjectiveTo observe the efficacy and safety of house dust mite vaccine in the treatment of house dust mite-allergic rhinitis.Methods47 patients with allergic rhinitis were recruited into the study.The course of SIT was treated by house dust mite vaccine for 51 weeks.Self-contrast method was used to compare the symptom score,nasal airway resistance before and after treatment.Then we observed the security in the process of injection.ResultsThe symptom score was (7.40 ± 1.64) vs ( 3.40 ± 1.50 ) pre and post therapy.Nasal airway resistance were (2.02 ±0.72) vs ( 1.06 ± 0.81 ) kPa · s -1 · L-1.Both the values of the data had significant differences( t =15.49,4.44,all P ＜ 0.01 ).No serious adverse reaction was observed.ConclusionSIT was able to improve the clinical symptoms and decrease nasal airway resistance.House dust mite vaccine was an effect and safe drug for the dust mite allergic asthma patients.

Objective To explore the curative effect of oral cancer radical surgery plus free anterolateral thigh flap repair and analyze the influence factors of skin flap necrosis.Methods The data of 98 patients who underwent oral cancer radical surgery with concurrent free anterolateral thigh flap repair in our hospital from January 2010 to June 2015 were retrospectively analyzed.The complete survival rate of skin flaps and incidence of complications in all patients were statistically analyzed.The age,diabetes,infection in implanted skin flap area,smoking and mental status,etc.of patients with survived or necrotic skin flaps were compared between patients with survival flaps and patients with flap necrosis,and multivariate Logistic regression analysis was performed.Results Among the 98 cases,86 cases of flaps survived completely and the survival rate was 87.8%.Fifteen cases with the skin flap necrosis,the incidence of complications was 15.3%,including 7 cases of surgi-cal site infection and 5 cases of skin flap necrosis with massive hemorrhage.The donor site incisions of all patients were primary healing and the patients were satisfied with the postoperative appearance.Among the patients with flap necrosis,the incidence rates of ≥60 years old,with diabetes,infection in flap implanted area,smoking and poor mental state (41.7%,41.7%,58.3%,75.0%,83.3%)were higher than those corresponding proportions in the patients with with survival flaps(P <0.05).Multivariate Logistic regression analysis showed that age,diabe-tes,infection in implanted skin flap area,smoking and poor mental status were the influencing factors for flap necrosis.Conclusion Oral cancer radical surgery with concurrent free anterolateral thigh flap repair has good curative effects.The age,combined with diabetes,smoking,infec-tion in flap implanted area and poor mental state are the risk factors for flap necrosis in patients with oral cancer after flap repair,which should be given intervention to improve the survival rate of skin flap in clinic.

Objective:To explore the essence of Radix Morindae Officinalis in strengthening bones through observing the effect of medicated serum of Radix Morindae Officinalis on cultured osteoblast in vitro. Methods:The medicated serum of Radix Morindae Officinalis was added to the osteoblasts which were separated from the cranium of 24-hours newborn SD rat,in order to determining the effect of TGF-?1 and the proliferation and secreting of alkaline phosphatase and osteocalcin of the osteoblasts. Results:The proliferation of the osteoblasts were signifi cantly stimulated by the alcohol and the n-butanol extract from the Radix Morindae Officinalis; and the n-butanol extract from the Radix Morindae Officinalis could promote differentiating OB excreting the ALP and OC;in addition,the ability of the osteoblasts expressing TGF-?1 was promoted by the n-butanol extract from the Radix Morindae Officinalis. Conclusion:The n-butanol extract from the Radix Morindae Officinalis can promote the ability of the osteoblast in expressing TGF-?1 mRNA and excreting the ALP,and further promote the growth of bone.

Chronic active Epstein - Barr virus infection(CAEBV) is an uncommon outcome of EBV infection and may present as severe of fulminant syndrome with high- mortality. It is characterized by chronic or recurrent infectious mononucleosis-like symptoms persisting over a long time and by an unusual pattern of anti-EBV antibodies. Although it occurs in immunocompetent individuals, a number of subtle immunologic defects have been reported in patients with CAEBV. Up to now, there are still no diagnostic criteria of CAEBV in China,so the author introduce it with respect to its diagnosis,history,pathogenesis and therapeutic approaches.
