Objective To investigate the effects and mechanism of Shufeng Decoction resisting type I hypersensitivity. Methods Type I hypersensitivity was induced by OVA. The content of IL-4, IFN-? and IgE in serum of the rats treated by Shufeng Decoction were determined by ELISA. Results Shufeng Decoction can increase the content of IFN-? in model rats (P0.05). IFN-?/IL-4 of Shufeng Decoction was significant higher than model group (P0.05). Conclusion The effects and mechanism of Shufeng Decoction on prophylaxis and treatment of type I hypersensitivity of skin (acute urticaria) may be related with regulating cell factors and influencing the balance of Th1/Th2.

Objective To adopt the network meta analysis method to compare the incidence difference of cutaneous squamous-cell carcinoma(SCC)and rash in 5 kinds of targeted drugs regimen for treating malignant melanoma.Methods PubMed and Cochrane Library databases were retrieved by computer.The retrieval range was from their establishment to November 2015.The network meta analysis pooled the evidences of direct and indirect comparison for evaluating the pooled odds ratio(OR)and cumulative probability of cutaneous complications occurrence difference in 5 kinds of targeted drugs regimen for treating malignant melanoma.Results Six randomized controlled trials(RCTs)conforming to the inclusion criteria were included.The meta analysis results revealed that compared with Dabrafenib+Trametinib,the cutaneous SCC occurrence rate of Vemurafenib was higher(OR=9.20,95％CI=1.26-52.53),while the rash occurrence rate of Vemurafenib+Cobimetinib was higher(OR=6.81,95％CI=1.01-41.87).The surface under the cumulative ranking curves(SUCRA)value showed that adopting Trametinib had the lowest occurrence rate for SCC,and adopting Dabrafenib+Trametinib had the lowest occurrence rate of rash.Conclusion Dabrafenib+Trametinibis generate the lowest complication incidence rate of malignant melanoma.

Objective To investigate the effects and mechanism of Xiaomin granules on type Ⅰ hypersensitivity.Methods The experimental animal model was made for type Ⅰ hypersensitivity.The mice were divided into five groups named vacant control group,Xiaomin granules(low-,middle-and high-dose) group,chlorpheniramine group randomly and were given homologous medication respectively.Results Xiaomin granules can inhibit capillary penetrance caused by histamine and 5-HT in mice(P 0.05).Xiaomin granules could inhibit the mice hind paw edema degree caused by histamine.The further study found that Xiaomin granules could decrease anaphylactic shock of the mice and decrease the death rate.Conclusions Xiaomin granules could restrain type Ⅰ hypersensitivity by inhibiting inflammatory mediators.

Objective To evaluate the effects of problem-based learning (PBL) teaching mode and lecture-based learning (LBL) teaching mode applied in clinical teaching of dermatology in China.Methods All studies on PBL teaching mode and LBL teaching mode applied in clinical teaching of dermatology in China published from 1990 to 2015 were identified by searching in CNKI,VIP database,Wanfang data and so on.Meta-analysis was performed by RevMan 5.3 software.Results Six random controlled trials on 710 clinical students qualified for the meta-analysis according to our criteria.The students in PBL group got significant higher scores than those of the students in LBL group in theoretical scores [WMD=3.75,95％CI=2.58-4.92,P＜0.05],clinical skills tests [WMD=5.27,95％CI=4.60-5.94,P＜0.05] and total scores [WMD=7.93,95％CI=6.49-9.37,P＜0.05].Conclusion PBL teaching mode is an effective mode on teaching of dermatology in China,particularly for theoretical scores and clinical skills,compared with LBL mode.

Objective To observe the effects of Grifola frondosa polysaccharide on T cell subsets and Th1/Th2 subsets of spleen deficiency mice, and investigate its immunoregulation mechanism. Methods Forty-eight KM mice were divided into 6 groups:normal group, spleen deficiency group, positive group (lentinan), three dosage groups of Grifola frondosa polysaccharide, 8 mice in each group. The mice were injected corresponding drug intraperitoneally for 10 days. Then mice in each group were detected CD3+, CD4+ and CD8+T cell by flow cytometry. IFN-γ and IL-4 levels were detected by ELISA. Results The high dose of Grifola frondosa polysaccharide could significantly increase the CD4+T lymphocytes percentage in peripheral blood (P<0.05). Medium and high dose of Grifola frondosa polysaccharide could significantly increase CD4+/CD8+T cell ratio (P<0.01) and CD3+T lymphocyte percentage (P <0.01) of spleen deficiency mice. Medium and high dose of grifola frondosa polysaccharide could significantly increase IFN-γ level in serum of spleen deficiency mice (P<0.01), and high dose of Grifola frondosa polysaccharide could decrease IL-4 level in serum of spleen deficiency mice (P<0.01). Conclusion Grifola frondosa polysaccharide can improve the decreased CD4+/CD8+T cell ratio which caused by spleen deficiency, and promote the transformation of Th1 to Th2, thus treating spleen deficiency syndrome.

Objective To investigate the expression and significance of TGF‐β receptor Ⅰ /TGF‐β receptor Ⅱ (TGF‐β Ⅰ /TGF‐β Ⅱ) in human skin malignant melanoma A375 cell line .Methods The reverse transcription‐real time polymerase chain reac‐tion (RT‐PCR) and Western blot were utilized to assess the expressions of TGF‐βR Ⅰ /TGF‐‐βR Ⅱ in A375 cell line and human normal melanocytes .Results The expressions of TGF‐βR Ⅰ /TGF‐‐βR Ⅱ mRNA and protein of A375 cells line were significantly lower than those of human normal melanocytes .Conclusion The down‐regulated expression of TGF‐βR in the TGF‐β/Smad signal pathway of human skin malignant melanoma may be one of the pathogenesis of skin malignant melanoma .

Objective Investigate the effective treatment for the stable subdural hematoma.Methods About the patients need for surgical treatment,for the treatment of hole drainage surgery,and according to the retrospective to be analyzed.Results The 68 cases of patients with surgical indications,under local anesthesia to surgery with the method of hole drainage surgery,achieve the desired results and objectives.Conclusions The hole drainage surgery is a simple way,and little chance of complications.As long as select the appropriate cases,during the surgery with standardized operation and at the end of surgery use standardized management,select the method of hole drainage surgery to treat the stable subdural hematoma is feasibility.

From May, 2000 to June, 2001, 27 patients with Parkinson disease (PD), including 10 cases of rigidity, 13 cases of tremor, 4 cases of rigidity and tremor, were treated by microelectrode-guided technique. Among them, phlebotomy was carried out in 17 cases and thalamotomy in 10 cases. All the targets of lesion were anatomically located by using MR and neurophysiological signals on microelectrode. Our results showed that the efficiency of microelectrode-guided technique for treatment of PD was 98%. The postoperative unified parkinson disease rating scale were 12.3 +/- 9.1 and 13.2 +/- 8.9 respectively, which significantly improved as compared with those before operation. It was concluded that by recognizing special electrical signals in neurons microelectrode-guided neuropsychological techniques can locate target at cellular level, which overcomes the individual difference in anatomy and function, and allow more accuracy, safety and efficiency of operation. This is especially true of PD patients who fail to respond to medical treatment.
