Pleomorphic adenoma (PA) is the most common benign tumor of the salivary glands. Originating from the nasal cavity is very rare. This paper reports one case of pleomorphic adenoma of the inferior nasal turbinate to analyze the clinic characteristic of this disease. Although these tumors are rarely seen in everyday practice, one should consider this possibility as an uncommon aetiology when confronted with an intranasal mass.

Histone deacetylase 6 (HDAC6) is an unique subtype of histone deacetylases with two tandem deacetylase domains and substrate specificity for non-histone proteins. It is involved in many important physiological and pathological processes and has become a promising therapeutic target in recent decades. Different kinds of potent HDAC6-selective inhibitors have been reported around the world. This paper reviews the progress in the study of structure and functions of HDAC6 as well as the development of HDAC6-selective inhibitors.

How to acquire new tumor antigens is a hotspot in cancer research currently.According to the nature of antigen epitope binding its ligand,we can identify and get unknown antigen epitope even its amino acid sequence through some analytical techniques and experiments,from T lymphocytes and monoclonal antibody levels.So the molecular mechanisms of tumor immunity will be more distinct.

Objective To observe the therapeutic effects of stellate ganglion block (SGB) with oxycodone and acetaminophen tablets on the treatment of migraine. Methods 100 patients with migraine were divided into two groups randomly. They received SGB with oxycodone and acetaminophen tablets (experimental group) or only SGB (control group) respectively. The parameters included pain intensity before and 1 d,3 d,1 w,1 m and 3 m after the treatment, and pain relief rate of each patient. The adverse effects were also evaluated. Results The pain intensity described as numeric rating score (NRS) decreased in the two groups at each time point. In the experimental group, the value of NRS was significantly less than that in the control group at 3d,1m and 3m after the treatment. The effec-tive rate ha the experimental group and the control group were 88% and 68%. Conclusion SGB with oxycodone and acetaminophen tablets is more effective for migraine and deserves widely used in patients.

Objective Investigate the effect of applying clinical pathway on the patients undergoing leiomyoma of uterus. Methods As an experimental group of patients, 50 cases of uterine leiomyoma are treated with clinical pathway. By contrast, another 100 cases are treated with the traditional medical care as control group. Results Waiting time for surgery and hospital stay of the experimental group are less than the control group; and the average hospitalization cost of experimental group is lower than the control group (P< 0.01). Conclusions Application of clinical pathway management will regulate the activities of medical treatment, ensure the quality of health care, improve the feeling of patients, increase efficiency of hospital services, reduce the financial burden of patients, increase the hospital social benefits.

AIM: To study the clinical curative effect of 2mm micro incision phacoemulsification combined with 23G minimally invasive vitrectomy for cataract and vitreoretinal diseases.METHODS: Retrospective analysis of 92 patients (99 eyes),including 49 male (53 eyes),43 female (46 eyes) with mean age was 57.1±1.9 years,in our hospital for cataract and vitreoretinal treatment of the disease from February 2013 to February 2016.All patients underwent 2mm micro incision phacoemulsification combined with 23G minimally invasive vitrectomy.Curative effect and complications were observed.RESULTS: Combined surgical procedures were carried out smoothly.posterior capsule rupture did not occurred.seven eyes were filled with BSS fluid,46 eyes with C3F8,49 eyes with intraocular lens at phase Ⅰ,21 eyes placed intraocular lens when silicone oil was removed.The visual acuity improved in 84 eyes (85%),unchaged in 15 eyes (15%).Postoperative complications included transient high intraocular pressure in 18 eyes (18%),anterior chamber reaction in 7 eyes (7%) and corneal edema in 8 eyes (8%).CONCLUSION: The 2mm micro incision phacoemulsification combined with 23G minimally invasive vitrectomy is a safe and effective surgical method with less injury,fewer complications.

[Objective]To simulate the biomechanics mechanism and environment of humeral fracture caused by indirect impact force for the purpose of biomechanics understanding and treatment of such fracture.[Method]Based on the data source, which was high-resolution anatomic slice images from approximal clavicle to distal humerus, 1 mm thickness and totally 380 layers, the geometric model of total shoulder joint was established according to the order:point, line,area, and further meshed to set up the three dimension finite element model of shoulder, fracture sites and instantaneous stress and strain of humerus were simulated and analyzed under the condition which longitudinal impact force was loaded on the humerus based on the 12 functional positions of shoulder(abduction 30?、 45?、 60?、 90?, and simultaneous neutrality, internal rotation 45?,external rotation 45?).[Result]According to the humeral shaft load-strain curve in different functional positions of shoulder, linear relation was found when load changed from 0 N to 250 N, after which non-linear come out, and even load was removed , bone was deformed eternally. With the rise in load amount, the increase in stress was detected. When abduction degree changed from 90? to 30?, the strain of humerus, both the lateral and the medial increased gradually,and increase in internal rotation 45?and external rotation 45? was more significant than that in neutrality. Meanwhile, stress difference could be seen between the lateral and the medial , and medial was larger than the lateral. Increase in stress in rotation positions was quicker and more than that in other functional positions.[Conclusion]Based on 4 abduction degrees (30?, 45?, 60?, 90?) and 3 rotation degrees(neutrality, internal rotation 45?,external rotation 45?) ,the three dimensional finite element shoulder could simulate precisely stress, strain, general trend of fracture line, three dimension images of bone failure. Three dimension finite element simulation and analysis of shoulder is a valuable mechanical method for research on biomechanics theory related to humerus fracture.

[Objective]To estimate the clinical effects of total hip arthroplasty(THA),bipolar and unipolar hemiarthroplasty for the treatment of femoral neck fractures(FNF) in the elderly.[Method]From February 1990 to February 2005,a follow-up study was done in 567 patients with femoral neck fractures in the elderly.The patients were divided into THA(n=275),bipolar hemiarthroplasty(n=195) and unipolar hemiarthroplasty(n=97) groups.The follow-up duration was from 3 to 15 years with an average of 8.5 years.The operation time,blood loss,volume of drainage,hospitalization time,complications and functional rehabilitation were compared.[Result]There were no statistical differences in the operation time,blood loss and volume of drainage between unipolar and bipolar hemiarthroplasty groups.There were no statistical differences in hospitalization time among the three groups.Compared with bipolar hemiarthroplasty,THR had a longer operation time and more blood loss,but had a higher functional scores and a lower rate of pain.Unipolar hemiarthroplasty had a lower functional scores and a higher rate of pain.[Conclusion]THR is especially suitable for those who are younger and active,bipolar hemiarthroplasty is suited to elderly patients,unipolar hemi-arthroplasty should be avoided because of its complications.
