Protein Kinase C (PKC) is an important messenger in intracellular signal transduction. So far, at least 11 members of PKC isoforms have been isolated and purified. The mutation of the non-synonymous SNP (1425G/A) of the η isoform of protein kinase C (PKC η), a protein kinase Cη gene (PRKCH) may result in the increased PKCη activity, which is considered as a new risk factor for lacunar infarction. In recent years, the studies about the role of PRKCH in cell differentiation and apoptosis and its relation with some signal transduction pathways have made some new advances, especially, PKCη participates in the regulation of some key enzyme activity that mitogen-activated protein kinase, inducible nitric oxide-synthase and matrix metalloproteinase are closely correlated with the process of atherosclerosis. It will provide a new way of thinking for the clinical intervention of cerebral infarction in the future.

Objective To compare the characteristic of high permeability dialysis(HPD) and conventional hemodialysis(CHD) and to study whether HPD was more effectively in elimination of the macromolecular, medium and small molecule urinary endotoxin in uremia than CHD.Method 48 cases of hemodialysis patients were randomly divided into two groups: HPD group(26 cases)given by high permeability dialysis, and CHD group(22 cases)given by conventional hemodialysis dialyzer. Two groups were observed prospectively for 2 years and renal function , electrolytes, ? 2 microglubulin, amino acid, protein concentration, endotoxin in blood serum were detected before and after hemodialysis respectively.Results The clearance rates of blood creatinine, blood urea nitrogen, uric acid , ? 2 microglubulin in HPD group were better than that of CHD group. Serum amino acid, endotoxin, serum phosphorum changes were no statistical significance after hemodialysis in two groups. Protein concentration after hemodialysis was higher than that before hemodialysis in two groups. Conclusions High permeability dialysis has all virtues of conventional hemodialysis dialysis and can clear macromolecular and medium molecule endotoxin, but conventional hemodialysis can not do.

Objective To survey symptom occurrence degree of maintenance hemodialysis (MHD) patients,and its related factors,and to provide a basis for clinical symptom management. Methods A total of 142 MHD patients were selected with convenience sampling method from a hospital in Ningxia from July 2015 to September 2015 and investigated with the Dialysis Symptom Index ,the Pittsburgh Sleep Quality Index and the family Adaptation,Partnership,Growth,Affection and Resolve(APGAR)Scale. Results The occurrence rate of various symptoms ranged from 53.5%to 92.3%. Fatigue(92.3%),itching(86.6%)and dry skin(85.9%)were the top three prevalent symptoms. Fatigue (30.3%),difficulty falling asleep (27.5%),hyposexuality (27.5%) and trouble in sleeping deeply(27.5%)were the most serious symptoms.Multivariate linear regression analysis showed that gender,nationality,sleep quality,combining with hypertension and arrhythmia had significant influence on the occurrence degree of symptom in MHD patients(P < 0.05). Conclusion Symptoms in MHD patients are preva-lent. Efficient symptom management should be performed to improve the quality of life of MHDpatients.

Abstract?AIM: To evaluate the clinical application of IOL Master by comparing with traditional ultrasound biometry on the accuracy and characteristics of intraocular lens calculation.?METHODS:Data was analyzed from 164 patients ( 206 eyes ) with age - related cataracts who underwent phacoemulsification and intraocular lens ( IOL ) implantation in our hospital from June 2014 to June 2015. Before surgery, axial length and corneal curvature were measured with IOL Master and combined application of ultrasonic or manual keratometry, respectively. Phacoemulsification and foldable lens implantation were done in the patients. IOL power calculation was carried out using the SRK-Ⅱformula with the basis of IOL Master data. The visual acuity and refractive outcome were followed-up for 3mo postoperatively.?RESULTS:There was a significant difference between the two methods on axial length measurement which was 23. 86 ± 1. 05mm by IOL Master and 23. 50 ± 0. 83mm by ultrasound ( P = 0. 025 ). There was also a significant difference between the two methods on corneal curvature measurement which was 44. 18 ± 1. 35D by IOL Master and 43. 70 ± 1. 41D by keratometry ( P = 0. 01 ). The mean absolute error(MAE), at 3mo after operation, was 0. 41± 0. 30D and 0. 93 ± 1. 10D by the IOL Master and ultrasound groups, respectively, there was a significant difference between the two methods(P=0. 027).?CONCLUSION:The IOL Master is a non-contact, safe,easy-to-do and patient-friendly methods for axial length and corneal curvature measurement with high accuracy, thus it can calculate the IOL power more accurate and improve the predictive value for postoperative refraction.

AIM:To perform a new method for orbital implant and contracted socket through one time and its results. ·METHODS:Totally 114 patients 114 eyes, from January 2008 to June 2014, with contracted socket participated in this study. We incised the bulbar conjunctiva horizontally and excised scar tissue, then implanted the hydroxyapatite in the four extraocular muscles and tightly sutured the Tenon ' capsule. After that, we put the superior and inferior conjunctival petals backwards and sutured them to the Tenon ' s capsule. All the patients were divided into four groups according to the vertical diameter length of the conjunctival defect area:GroupⅠ:≤5mm; Group Ⅱ: 6-10mm; Group Ⅲ: 11-15mm; and Group Ⅳ: ≥16mm. These patients were followed up for 6mo to 3y to observe the conjunctival sac shaping and growth of conjunctiva. ·RESULTS:There were 64 cases in GroupⅠ, 31 cases in Group Ⅱ, 16 cases in Group Ⅲ and 3 cases in Group Ⅳ. All patients ' conjunctival defect was covered by new conjunctiva and scar tissue 4 to 6wk after surgeries. Ten cases had contracted socket; 2 cases had orbital implant exposure, requiring reoperation. Of the 114 cases, 8 had contracted socket and could use a smaller conformer, 106 could use a normal size conformer. ·CONCLUSION: When the conjunctival defect was ≤15mm, this new method can address the orbital implant and contracted socket at the same time. While it was ≥16mm, flap transplantation is necessary.

Objective:To observe the effect of electroacupuncture (EA) at Jiaji (EX-B 2) points plus hydro-acupuncture with sinomenine hydrochloride for low back pain caused by compression fractures in the elderly.Methods:Ninety-five elderly in-patients with low back pain caused by compression fractures were randomly divided into an observation group and an EA group according to the visit sequence.Both groups received the same basic treatment.In the EA group,48 cases were treated with EA at Jiaji (EX-B 2) points plus the basic therapy;47 cases in the observation group received the basic treatment plus EA and hydro-acupuncture with sinomenine hydroch|oride at Jiaji (EX-B 2) points.The levels of osteoprotegerin (OPG) and interleukin-1β (IL-1β) in peripheral blood were measured by enzyme-linked immunosorbent assay (ELISA) before and at the 21st day of treatment in both groups.Oswestry disability index (ODI) and visual analog scale (VAS) scores were used to analyze the clinical efficacy.Results:After treatment,the OPG content in the observation group was higher with statistical significance compared with that before treatment in the observation group and after the treatment in the EA group,respectively (both P<0.05);the content of IL-1β,ODI and VAS scores were lower than those before treatment in the observation group and after treatment in the EA group with statistical significances (all P<0.05).Conclusion:The combination of EA and hydro-acupuncture with sinomenine hydrochloride at Jiaji (EX-B 2) points is effective for low back pain caused by compression fractures in the elderly,and is superior to EA at Jiaji (EX-B 2) points alone.

Herpes simplex virusⅠ(HSVⅠ) regulating the pathway of transcription and translation modify in host cell is a very systematic and complicate system. A clear understanding of the concrete mechanisms of infection will greatly help to comprehend the virus replication and the interaction with the host cell. By the analysis of 2-DE, the heterogeneous nuclear ribonucleoprotein H2 in human fetal liver cell represent distinction after the HSVⅠinfection.Utilization of Northern blot and Western blot technologies verified the expression of hnRNP H2 in different stage of virus infection is varied.
