Chemical synthetic drugs are the main therapeutic drugs for cancer, however, the time-consuming drug development, lengthy treatment, serious side effects and drug resistant of chemical synthetic drugs significantly increase the burden of the patients.In recent years, natural anti tumor substances with good treatment effectiveness and low toxicity, have attracted more and more attentions in studying anti tumor drugs.It is reported that Inonotus obliquus can significantly suppress tumors, while the antitumor components and mechanisms of Inonotus obliquus are rarely reported.In this paper, we will review the antitumor effect, antitumor components and mechanisms of Inonotus obliquus.

Objective To evaluate the application effect of bedside evaluation of deglutition function and predictive nursing intervention on patients with dysphagia in neurology department. Methods 320 Patients with dysphagia were divided into the observation group and control group with 160 cases in each group. The observation group was given admission nursing evaluation and bedside evaluation of deglutition function while the control group only received admission nursing evaluation. The incidence of complications in each group were assessed. Results The incidence of complications such as aspiration, pulmonary infection, asphyxia and metabolic disturbance in the observation group was lower than that of the control group(P＜0.01).Conclusion The bedside evaluation of deglutition function could accurately evaluate the degree of swallowing disorder and supply theoretical evidence for predictive nursing intervention by in structing clinical application of selective measures for patients with dysphagia. This could guarantee safe food intake and reductive incidence of complications of patients. So we advocated that bedside evaluation of deglutition function should be a routine admission nursing evaluation in neurology department.

Objective To observe the distribution of circum-patella nerve fibers in the soft tissue to provide experimental evidence,which is significant in denervation for Total Knee Arthroplasty (TKA).Methods Patella specimens were collected from 4 cadavers (2 cases of diabetic foot,lcase of lower extremity arterial occlusive,and 1case of car accident),all 4 of which were resected soft tissue with a dimension of 0.5cm × 0.5cm and full depth thickness around patella more than 0.5cm for histology and morphology observation.The nerve fibers histology and morphology were observed in all resected specimens with HE staining and silver-gilt glycine staining in the same field of microscopic vision.Results Anatomy found that the vascular network form skins directly involved in the patella nourish hole area and in the 10,2,4,7 clock point have found that blood vessels into the patella.There have a large number of nerve fibers near to the patella under the microscope,but there were no significant difference in the nerve fibers region distribution of all specimens.There were some into patella nerve fiber paths in side of patella soft tissue,which lied in 7,11 and 13 clock point,but outside no this phenomenon.The distribution of circum-patellar nerve fibers were described as distribution of regional concentration,which lied in much more 5,6,7 clock points and 10,11,12,1,2,clock points,in which the quadriceps tendon and patellar tendon have more than the others.In the 13 clock point,the fascia and periosteum of nourish hole area were also found in a large number of nerve fibers,and there were laminar distribution in different soft tissue layers,which were collected much more in synovial layer,fat pad,tendon near to patella.Conclusion There are much more nerve fibers near to the patella and some into patella nerve fiber paths in the medial side and nourish hole area.Nerve fibers distribution of circum-patella can be described as laminar distribution and regional concentration ,which is more in the centre,bottom more than top,outside more than inside,the bipolar more than the others.The patella denervation operation by reducing the number of peripheral nociceptors to achieve desensitization is feasible in TKA.

Objective Our aim was to investigate the association between sudden sensorineural hearing loss (SSHL)and mean platelet volume (MPV)values,in order to evaluate the etiology of SSHL.Methods This study included 40 patients with SSHL in our ward between Jan.2012 and Jan.2014 and 30 age- and sex-matched healthy subjects were included as controls.The correlation among the levels of the number of platelets,mean plate-let volume(MPV),platelet distribution width (PDW)was evaluated in the two groups.ResuIts The platelet count was significantly lower in the SSHL than the control group(212.0±47.9 versus 237.8±46.2 ×109/L).MPV and PDW were significantly higher in SSHL(10.9±0.8 versus 10.3±0.8 fL;12.9%±2.0% versus 12.0%±1.3 %). The SSHL patients were divided two subgroups:the mild-moderate subgroup (hearing loss 25~70 dB)and the se-vere subgroup(hearing loss≥70 dB).The MPV values were insignificantly different between the two subgroups(11. 0±1.1 fL versus 10.8 ±1.0 fL).Compared to the control group,the two subgroups had both significant differ-ences in MPV.ConcIusion High MPV values are a risk factor for thrombotic vascular diseases.Considering the in-creased MPV levels,SSHL appears to be characterized by ischaemic or thrombotic events.

Objective:To improve the method for isolating platelet-rich plasma (PRP). Methods:Whole blood was collected from 8 healthy donors and then PRP was separated by both the tube method and the syringe method respectively. Samples were activated to get serum rich-in growth factors (SRGF).Platelets in the SRGF were counted and the level of TGF-?1 was assayed by enzyme-linked immunosorbent assay (ELISA).Results:The end product of syringe method has both a higher platelet count in PRP (P=0.003) and a higher level of TGF-?1 in SRGF(P=0.041) than that of tube method.Conclusion:The syringe method is an effective method in preparation of PRP.

OBJECTIVE To study the clinical features of OSAHS patients closely associated with supine position. METHODS The clinical data of 105 patients with OSAHS diagnosed by overnight polysomnography(PSG)were retrospectively studied. The patients were divided in two groups: the positional patients(PP)group, those patients who had a apnea-hypopnea index(AHI) that was at least two times higher than the lateral AHI, and the non-positional patients(NPP)group, those patients in whom the AHI in the supine position was two times less than that in the lateral position, and the two groups were compared with age, BMI and the severity of OSAHS. RESULTS The difference of age and BMI were not significant between the two groups[(40.4?10.5)year versus(37.0?10.6) year,(28.2?3.8)kg/m2 versus(29.1?3.0)kg/m2]. There was significantly different in AHI between two groups[(36.8?25.4)/h versus (51.2?29.0)/h ]. AHIsupine and AHInot-supine was significantly different in mild and moderate OSAHS patients [(23.9?13.8) /h versus(12.4?10.1)/h ]. CONCLUSION Mild and moderate OSAHS patients are mainly PP. Positional therapy should play an important role in treatment of mild and moderate patients.

180 U/L.CK-MB raised in only 5 cases(15.6%),and the highest was 28 U/L.Of the 218 MPP patients,only the 5 patients(2.3%) with raised CK-MB levels could be diagnosed as myocardial damage complicated with MPP.Conclusions The abnormal ECG is more important than myocardial zymogram in the diagnosis of myocardial damage complicated with MPP.Only higher level of certain myocardial zymogram without abnormal ECG can not be diagnosed as myocardial damage if lack of clinic and other objective evidences for myocardial damage.In watching out for myocardial damage,excessive examinations and treatments shall be avoided if possible.

Objective: Our aim was to evaluate the role of TGF-β1 mRNA in pulmonary fibrosis. Methods: The present study was taken to investigate the expressions of TGF-β1 mRNA in alveolar macrophage（AM) and lung tissues in different stages of bleomycin-induced pulmonary fibrosis in rats through reverse transcript polymerase chain reaction. Results: In bleomycin-treated rats, the expressions of TGF-β1 mRNA was remarkably increased in AM from 3rd day (P< 0.05) , and reached the peak on 7th day (P<0.01) , there was also a continuing high level from 14th day to 28th day (P>0.05). It showed similar pattern with that in lung tissues. Conclusion: There were TGF-β1 mRNA expression in both normal rats and pulmonary fibrosis rats. AMs seemed to be the main source of TGF-β1 mRNA in lung tissues, especially at stage of alveolitis.
