[Objective]Through the anatomical observation and measurement on middle and distal humerus and radial nerve,To investigete a new radial nerve transfer operation.[Method]By means of anatomical methods,radial nerve's stretching branch,the relationship between radial nerve and deep brachial vessel in 30 upper climbs were observed and measured on 15 adults fixed in 10% formalin.The anatomical structures of humerus of one hundred specimens were also observed.This data were made by designing and performing the radial transfer operation after statistical analyzing.[Result](1)Length of humerus: The left side was (30.60?1.46)cm and the right side(31.37?1.23)cm.The length of sulcus for radial nerve: the left side was(5.65?1.01)cm and the right side(6.57?0.58)cm.The stretch angle of radial nerve: the left was 13.00??1.08?,the right13.86??0.97?.(2)The stretch angle of radial nerve: the radial nerve in the sulcus for radial nerve went from superomidial region to lateral lower region and the angle open to the inner part was formed.The angle is obvious in 29 sides,that was 96.67%,and not obvious only in 1 side,that was 3.33%.(3)The position of the radial nerve superficial and deep branches: The radial nerve in 17 sides branches were above interepicondylar line,which was 76.67%.Below the line were 10 sides,cover 33.33% and on the line 3 sides,cover 10.00%.(4)The curve distance between the exit of radial nerve and the brarnches was(14.26?1.01)cm.(5)The relationship between radial nerve and deep brachial vessel: the radial nerve lies inside of the deep brachial vessel were 12 sides,lies the outside of the deep brachial vessel were 10 sides and cross the deep brachial vessel were 8 sides.[Conclusion]The design of radial nerve transfer operation is reasonable,it conforms to the radial nerve's anatomy and physiology and provides much wider operation space for the performing of all kinds of internal fixation on fractures of middle and distal humerus.It reduces the injury of the radial nerve in the course of the operation and alter the operation while taking the internal fixation substance out.It doesn't increase the difficulty and injury.

Penicillin is a kind of β-lactam drug which has been applied in the clinical treatment firstly in the world, and it has still been widely used at present. The synthesis and regulation mechanism of Penicillium chrysogenum, which is used to produce penicillin, has been studied quite maturely, but its proteomics research started relatively late and fewer reports were published. This paper reviews the synthesis and application of penicillin, transformation of Penicillium chrysogenum, and the research progress of its proteomics. On this basis, the study highlights the advantages of proteomics in the research of protein expression.

Objective To investigate the imaging and pathological features of atypical teratoid/rhab doid tumor (AT/RT)occur-ring in the central nervous system (CNS).Methods The CT and MRI findings of 1 6 patients with CNS AT/RT were retrospectively analyzed,and their pathological and immunohistochemical results were studied.Results There were 12 males and 4 females. Tumors located is at supratentorial in 10 and infratentorial in 6.Cystic changes in tumors were noted in 12 cases.The solid portion of tumors was isointense on T2-weighted images relative to normal brain grey matter in 9 patients.Extensive peritumoral edema was observed in 1 1 lesions.The tumors showed bandlike rim of significant enhancement in 10 cases.The incidence of hemorrhage and calcification in tumors were 43.8% and 41.7% respectively.Histopathologically,AT/RT was characterized by the presence of rhab-doid cells associated with variable components of epithelial,primitive neuroectodermal and mesenchymal differentiation.Conclusion Atypical teratoid/rhabdoid tumor is several imaging findings which are relatively specific on CT and MR images.CT and MRI may provide valuable information for pre-operation diagnosis and prognostic evaluation in patients with CNS AT/RT.

Objective To investigate the clinical features of child-onset relapsing polychondritis (CORP). Methods The clinical manifestations of 11 CORP cases were analyzed retrospectively. Results Eleven cases of CORP were collected with Male to Female ratio of 5 ∶6; the mean age of disease onset was (11±4)(3-15) years; and the mean age of final diagnosis was(16±5)(6-22) years-old. The mean time of delay of diagnosis was(55±46)(2-144) month. Nine cases were simple CORP and 2 cases were concurred with SLE and pSS respectively. Laryngotracheal symptoms as initial presentation was seen in 7/11(64%) of cases, followed by rhinitis, eye involvement and arthritis. Laryngotracheal involvement occurred in 10/11 (91%) cases and 6/11(55%) underwent trachectomy when the diagnosis was made, followed by eye and nose involvement (saddle nose)(46% each), involvement of auricular cartilage,vestibule disorder and arthritis (36% each). Elevation of ESR or CRP(36%) were observed and positive autoantibody(18%) were detected in serology study; 9/11 (82%) were treated with steroid combined immunosuppressant. All cases were improvedor stable except 2 cases with exacerbation after upper respiratory infection during the follow-up of mean(27±15)(4-48) month. Conclusion Laryngopharyngeal involvement is the most common phenomenon in CORP and is associated with poor prognosis due to diagnosis delay. Imaging investigation may provide useful evidence for early diagnosis. Aggressive treatment is helpful in improving outcome.

Objective To observe and study the influence degree of strengthen training for family members for the treatment compliance and unhealthy lifestyle of patients with diabetes mellitus. Methods A total of 64 patients with diabetes mellitus from January 2015 to March 2016 were selected and divided into two groups by the method of random number table,32 patients in control group were taken care with routine nursing of diabetes mellitus,32 patients in observation group were taken care with strengthen training for family members,then the treatment compliance,related knowledge cognition of unhealthy lifestyle and unhealthy lifestyle situation of two groups before the intervention and at 4th, 8th and 12th week after the intervention were compared. Results The treatment compliance, related knowledge cognition of unhealthy lifestyle and unhealthy lifestyle situation of two groups before the intervention all had no obvious differences (all P>0.05). The treatment compliance at 4th, 8th and 12th week after intervention were (6.26 ± 0.32), (6.95 ± 0.36), (7.28 ± 0.40) scores in observation group, and (5.23 ± 0.29), (6.01 ± 0.30), (6.30 ± 0.33) scores in control group, and the differences were significant (t=8.253, 9.201, 10.257, all P<0.05). The related knowledge cognition of unhealthy lifestyle at 4th, 8th and 12th week after intervention were (80.78±5.90), (89.44±6.02), (93.43±6.20) scores in observation group, and (73.38± 5.73), (77.93±5.84), (82.20±6.01) scores in control group, and the differences were significant (t=11.258,12.563, 13.324, all P<0.05 ). The unhealthy lifestyle situation at 4th, 8th and 12th week after intervention were 75.00%(24/32), 90.63%(29/32), 96.88%(31/32) in observation group, and 59.38%(19/32), 68.75%(22/32),78.13%(25/32) in control group, and the differences were significant (χ2=7.251, 7.468, 9.169, all P<0.05). Conclusions The influence of strengthen training for family members for the treatment compliance and unhealthy lifestyle of patients with diabetes mellitus are more active, so the value of strengthen training for family members of patients with diabetes mellitus is higher.

Objective To investigate the expression and significance of Th9, Th17 and CD4+CD25+Foxp3+regulatory T (Treg) cells as well as the related cytokines (IL-9, IL-17, TGF-β) in peripheral blood of patients with adult primary immune thrombocytopenia ( ITP) . Methods Peripheral blood samples were collected from 47 patients with ITP and 39 age-and sex-matched healthy subjects. The percentages of Th9, Th17 and CD4+CD25+Foxp3+Treg cells in peripheral blood samples were detected with flow cytometry. The levels of IL-9, IL-17 and TGF-βin serum samples were detected by enzyme linked immunosorbent assay ( ELISA) . Results Compared with healthy subjects, the percentages of Th9 and Thl7 cells and the concen-trations of IL-9 and IL-17 in patients with ITP were significantly increased [(1. 27±0. 31)% vs (0. 71± 0. 26)%, P<0. 05;(2. 01±0. 42)% vs (0. 97±0. 32)%, P<0. 05. (26. 52±7. 48) ng/L vs (16. 16± 5. 27) ng/L, P<0. 05;(10. 97±3. 94) ng/L vs (7. 14±2. 73) ng/L, P<0. 05]. The percentages of CD4+CD25+Foxp3+ Treg cells and the concentrations of TGF-β in patients with ITP were lower than those in healthy subjects [(4. 69±0. 85)% vs (7. 16±1. 92)%, P<0. 05. (3. 76±1. 28) μg/L vs (6. 41±1. 83)μg/L, P<0. 05]. Moreover, the blood platelet counts in patients with ITP were negatively correlated with the percentages of Th9 and Th17 cells and the concentrations of IL-9 and IL-17 (γs=-0. 349, P=0. 037;γs=-0. 392, P=0. 031;γs=-0. 436, P=0. 014;γs=-0. 401, P=0. 027), but were positively correlated with the percentages of CD4+CD25+Foxp3+ Treg cells and the concentrations of TGF-β (γs=0. 411, P=0. 024;γs=0. 407, P=0. 026). Conclusion The imbalanced distribution of Th9, Th17 and Treg cells and the abnormal expression of related cytokines (IL-9, IL-17 and TGF-β) in patients with ITP might be the possible immunological pathogenesis of ITP.

Objective To explore target organ damage in the youth with pre-hypertension. Methods 77 consecutive youth visiting our institution form 2008 to 2010 were divided into pre-hypertension group (n=32) and control group (n=45). The relevance of left ventricular mass index (LVMI), left ventricular end-diastolic diameter (LVDd), interventricular septum thickness (IVST), left ventricular posterior wall thickness (LVPWT), carotid plaque intima-media thickness (IMT) and glomerular filtration rate (GFR) were compared. Results The blood pressure of pre-hypertension group was higher than that of control group, and the pre-hypertension group followed higher family hypertension history (P<0.05). There was no difference in LVDd, IVST, LVPWT, carotid plaque IMT and GFR between 2 groups (P>0.05). Compared with the control group, LVMI increased (P<0.05) and the E/A ratio decreased (P<0.05). Conclusion Target organ damage in pre-hypertension youth is salient compared with changes in renal function and damage of arteriosclerosis, and heart damage is more often occurred in the obese youth with pre-hypertension.
