OBJECTIVETo study clinical effects of surgery for the treatment of Mayo II B comminuted fracture in ulna olecranon.

METHODSFrom May 2008 to March 2015, a total of 37 patients with Mayo II B comminuted fracture in ulua olecranon were treated, including 20 males and 17 females, ranging in age from 40 to 65 years old ,with an average of 53 years old. All the patients were treated with open reduction and internal fixation within 4 to 7 days after injuries. All the patients had pain and functional disorder uf elbow joint. The X-ray and CT examination showed ulna olecranon comminuted fracture of Mayo II B. Postoperative complications were observed ,and Broberg-Morrey criteria was used tu evaluate therapeutic effects.

RESULTSAll the patients were followed up ,and the duraiton ranged from 9 to 30 months ,with a mean of 15 months. Two patients had surface infection around incision ,and were healed by changing dressings. No other complications occurred such as needle slipping to stimulate skin ,screw loosening and wire broken. One patient had slight uneveness of joint surface without obvious functional disorder. According to Broberg-Morrey elbow fracture curative effect criteria, 11 paients got an excellent result, 24 good and 2 fair,and the total score was 87.0 ± 7.3.

CONCLUSIONFor the Mayo II B comminuted fracture in ulna olecranon, preoperative preparation, intraoperative restoring of the articular surface smooth and reasonable internal fixation, and postoperative rehabilitation actively, can obtain satisfactory clinical effects.

Background The study on normal stem cell markers provides a new way of thinking of that pathogenesis of cancer research and looking for specific markers of cancer stem cells.Importin13 (IPO13) is a novel nucleus-cytoplasm transport receptor protein of importin β family,the study on the biological behavior of IPO13 in ocular tissue and limbal neoplasms is lacking.Objective This study was to investigate the differential expression of IPO13 and p63 in human benign and malignant conjunctiva-cornea neoplasms.Methods The specimens of normal donor limbal and conjunctival tissues (6),conjunciva-cornea papilloma (CCP) (6) and conjunctiva-cornea intraepithelial neoplasia(CCIN) (6)were collected from Xiangya Hospital of Center South University.The expressions of IPO13 and p63 in the corresponding tissue were qualitatively and quantitatively detected using immunochemistry.The A values of IPO13 and p63 positive response were calculated and compared among the 3 types specimens.Results The immunohistostaining on frozen sections showed that IPO13 was expressed in nuclei of basal cells of limbal and conjunctival epithelium and the cellular nuclei of basal cells and suprabasal cells of CCP and CCIN epithelium.The A values of IPO13 positive expression were 1687± 1014,3546± 1375 and 7635 ±2854 in the normal limbal specimen,CCP and CCIN,respectively,showing a significant difference among them (F =7.23,P＜0.05),and the A value was higher in the CCP and CCIN than that in the normal limbal tissue (q =4.02,5.13,P＜0.05),and that in the CCIN was significantly elevated in comparison with CCP(q =3.45,P＜0.05).p63 was expressed in nuclei of basal cells and suprabasal of limbal,conjunctival and CCP epithelium,and was expressed in nuclei of the entire CCIN epithelium.The expressions of p63 in the normal conjunctiva-cornea tissue,CCP and CCIN were 2110± 1229,3966± 2129 and 6650± 2136 respectively,with significant difference among the three different specimens (F =6.17,P＜ 0.05),and the A value of p63 positive expression was significantly elevated in the CCP and CCIN compared with normal limbal specimen (q =4.33,5.01,P＜0.05),and that in the CCIN was significantly elevated in comparison with CCP(q=3.83,P＜0.05).Conclusions IPO13 is more specifical in marking the poorly differentiated cells in limbal epithelial proliferative lesions than p63.Compared with the normal limbal specimen,the expressions of IPO13 and p63 in CCP and CCIN specimens gradually upregulat,which suggests that IPO13 and p63 may play a positive regulatory role in conjunctiva-cornea proliferative lesions.The differential expression of IPO13 and p63 is predominant between benign and malignant limbal epithelial proliferative lesions,indicating that IPO13 and p63 may play an important role in regulating the abnormal proliferation and differentiation of limbal epithelial proliferative lesions.

Observed index is a very important element in a research design, because it is a specific reflection of the effects of research factors on the research subjects and is indispensable in any research. Generally, there are two types of observed indexes: the indexes that reflect natural attributes, habits or states of the research subjects and the indexes that reflect the effects of different drugs or treatments on research subjects. This article mainly introduces the definition, characteristics, selection and observation of research indexes and the major and minor indexes.

Objective To observe the effect of auricular-plaster therapy on non-incisional pain from post-laparoscopic surgery.Methods Sixty patients with non-incisional pains from laparoscopic surgery were divided into experimental group (n=30) and control group (n=30).The patients of control group after laparoscopic surgery were routinely given the oxygen inhalation for 6 hours and encouraged to do off-bed activity earlier.Besides the above-mentioned treatment,the patients of experimental group were additionally given auricular-plaster therapy.The patients of two groups were compared in terms of pain intensity and duration.Result The pain duration in the experimental group was significantly shorter and the pain density was significantly lower than that of the control group (bothP<0.05).Conclusion Auricular-plaster therapy can significantly reduce the duration and intensity of non-incisional pain from gynecological laparoscopy.

Intrauterine growth retardation (IUGR) is one of the most commonly encountered developmental toxicity, which could lead to perinatal morbidity and mortality, be also extended from the fetus to adulthood, and seriously affect the quality of the population. Caffeine widely exists in a variety of daily beverages and some drugs. Its consumption is increasing year by year. Caffeine intake during pregnancy is one of the risk factors for IUGR. However, its mechanism of adverse outcome based on embryonic research is still unclear. In this paper, the possible mechanisms of caffeine-induced IUGR focusing on 3 important factors-the mother, placenta and fetus were explored. Caffeine's impact on the mother is the chronic activation of renin-angiotensin system; on the placenta, caffeine induces cell damage or the failure of the cell proliferation/apoptosis balance, leading to blockage of blood supply to the placenta; caffeine is also capable of directly affecting fetal development through interfering its neuroendocrine.

Background One of the difficulties in identifying early glaucoma is the variability of perimetry performance.For this reason,a field defect have to be reproduced more than two consecutive examinations before it is confirmed.The relationship between visual field sensitivity and retinal nerve fiber layer (RNFL) thickness may give us a more efficient and objective assessment to the early diagnosis of glaucoma.Objective This diagnostic test was to evaluate the application of functional-structural relationship between automated perimetry and RNFL in the early diagnosis of open-angle glaucoma.Methods Sixty-four eyes of 64 patients with early open-angle glaucoma and 50 eyes of 50 normal volunteers with the matched age and gender were enrolled in Xiangya Hospital January to June 2007.Visual field examinations,including standard automated perimetry (SAP),short wave automated perimetry (SWAP),and imaging of scanning laser polarimetry with variable corneal compensation(GDxVCC),were performed on the subjects with the informed consent.The sensitivity and specificity of the joint or single measurement of GDxVCC,SAP and SWAP under the local diagnostic criteria,and overall diagnostic criteria were calculated.Results According to the overall diagnostic criteria,the sensitivity of GDxVCC,SWAP and SAP were 70％,63％,61％ respectively,and the specificity were 84％,80％,78％,respectively.According to the local diagnostic criteria,the sensitivity of GDxVCC,SWAP and SAP were 78％,86％,78％,respectively,and the specificity were 54％,40％,50％,respectively.With the local diagnostic criteria,the sensitivity and specificity of serial test of GDxVCC,SWAP and SAP were 86％ and 90％ respectively,and the positive likelihood ratio and negative likelihood ratio were 8.59 and O.16,respectively.Conclusions The functional-structural relationship between automated perimetry and RNFL which can provide valuable individual diagnostic information for patients,and serial test of GDxVCC,SWAP and SAP can reduce the false positive rate and improve the diagnostic performance significantly.

OBJECTIVETo evaluate clinical outcomes of fixation for the treatment of radial head fracture with collapse of anterior articular surface.

METHODSFrom March 2006 to January 2013,17 patients with radial head fractures with collapse of anterior articular surface were analysed. According to the Mason classification, there were 12 cases with Mason type II fractures and 5 cases with Mason type III fractures. All the patients were treated with open reduction through posterolateral entrance of elbow joint and Herbert or titanium cannulated screw internal fixation.

RESULTSAll the patients were followed up, and the duration ranged from 6 to 18 months, with a mean of 11.3 months. According to the Broberg and Morrey score system, 2 patients got an excellent result, 12 good and 3 fair. There were no complications such as infection of elbow joint, nerve injury, non-union, traumatic osteoarthritis, heterotopic ossification and elbow instability. However, the postoperative activity range of elbow in the injuried side was less than that in the normal side.

CONCLUSIONRadial head fracture with collapse of anterior articular surface is easily misdiagnosed, and it can be treated with open reduction and internal fixation through posterolateral entrance.

To investigate and analyze the epidemiology of serious corneal ulcer.
● METHODS: A total of 133 serious corneal ulcercases from June 2010 to December 2013 in Xiangya Hospital Affiliated to Central South University were retrospectively reviewed for risk factors, demographic characteristics and diagnosis.
●RESULTS: There were 91 male patients (68. 4%) in the 133 patients. A peak incidence age was from 41 to 60 years old (82 cases, 44. 4%). Most of patients were peasant (77 cases, 57. 9%) and the percentage of the low schooling patients was 85. 0% (113 cases). The number of patients who had been sick was 73 before hospitalization (54. 9%) in all cases. The peak incidence season was January (34. 6%). Average length of stay was 9. 84d. The number of emergency cases was 44 (33. 1%). Most of patient were not only corneal ulcer cases but the hypopyon (92 cases, 69. 2%). The figure of inpatients who received operations was 102 cases ( 76. 7%). And the most of operations was amniotic membrane transplantation (31 cases, 39. 2%). Additionally, this data was classified regard to gender differences.
● CONCLUSlON: The peasant of the middle age and elderly represents a distinct clinical group in the serious corneal ulcer in hospital. Severity, ocular trauma in agriculture and health awareness are the major predisposing factors.
