Objective To find a new method of tangential view of patello femoral joint. Methods 62 cases of lateral knee radiographs were studied. The knee flexion angles, patello femoral angles, patello tibial angles and frontal patello tibial angles were measured and their relationships analyzed. The knee flexion angles and the patello femoral angles had linear relationship with a linear equation = 2 + 0.8x . The angles of posterior patellar line with tibial long axis and frontal tibial line were 3.3? and 12.7?respectively. According to the measurement results, an accessary positoning table was designed. The patients′ patello femoral joints were examined with the knee flexed at an angle of 30?. The patients were in supine position and the central X ray was angled at 73?vertically toward the film. Results 58 patello femoral joints of 40 patients were radiographically studied (10 males, 30 females) .All radiographs were classified into 4 degrees as Grade A, B, C and D. Eighteen cases were Grade A (31%), 30 cases were Grade B(52%), 8 cases were Grade C(18%)and 2 Grade D(3%).The reason for Grade D was due to small or negtive anterior patellotibial angles. Conclusion This new method of tangential view of patello femoral joint is accurate, comfortable and simple and could be used as routine examination for patello femoral joint diseases.

Objective:To compare the visual quality of patients with astigmatic multifocus intraocular lens (ART IOL) and astigmatic monofocus IOL (Toric IOL) after implantation.Methods:A prospective, non-randomized, controlled study was conducted to include 72 eyes of 72 cataract patients with corneal astigmatism (1.0-2.5 D) who were scheduled to receive phacoemulsification combined with IOL implantation in Chaoju Eye Hospital of Inner Mongolia from July 2017 to October 2018.Patients were divided into ART IOL group (37 eyes) and Toric IOL group (35 eyes) according to different IOLs implanted.All patients were followed up for 1 year after surgery.The main and secondary outcome indicators were compared.The main outcome indicators included distance (5 m), intermediate (80 cm), and near (40 cm) uncorrected visual acuity and best corrected visual acuity, defocus curve, contrast sensitivity, postoperative IOL rotation and residual astigmatism, while the secondary outcome indicators included visual subjective symptoms and spectacle independence rate.The above outcome indicators were compared between the two groups.This study followed the Declaration of Helsinki.The study protocol was approved by the Ethics Committee of Chaoju Eye Hospital of Inner Mongolia (No.CJYKLL202012).Written informed consent was obtained from each patient before surgery.Results:There was no statistically significant difference between the two groups in average uncorrected distance visual acuity and best corrected distance, intermediate and near visual acuity (all at P>0.05).The average intermediate and near visual acuity in the ART IOL group was significantly higher than that in the Toric IOL group, showing statistically significant differences (both at P<0.05).The defocus curve of the ART IOL group presented a double peak, which reached the peak at the far focus (0.0 D) and near focus (-2.5 D), respectively.The visual acuity range from 1.5 to-3.0 D was above 0.2 logarithm of the minimum angle of resolution (LogMAR), and the focus depth range was 4.5 D (1.5 to -3.0 D).The defocus curve of the Toric IOL group had only one crest, which was located at best corrected visual acuity (0.0 D).The visual acuity reached 0.2 LogMAR or above were from 1.0 to -1.0 D, and the focal depth range was 2.0 D (1.0 to -1.0 D).There was no statistically significant difference in contrast sensitivity at different spatial frequencies between the two groups in bright light, bright flashing light and dark light (all at P>0.05), while the contrast sensitivity of the ART IOL group at high dark flashing light frequency was lower than that of the Toric IOL group, showing statistically significant difference ( P<0.05).In the ART IOL group and the Toric IOL group, the average residual astigmatism after surgery was (-0.47±0.51)D and (-0.49±0.42)D, respectively, with no statistically significant difference ( t=0.408, P>0.05).There was no significant difference in postoperative IOL rotation between the two groups ( t=1.906, P>0.05).The total postoperative spectacle independence rate in the ART IOL group was 97.30%(36/37), which was higher than that in the Toric IOL group (17.14%, 6/35), showing statistically significant difference ( χ2=15.320, P<0.05). Conclusions:Both Toric IOL and ART IOL can better correct corneal astigmatism and improve patients' distance visual acuity, but ART IOL implantation can provide better distance, intermediate and near visual acuity, and higher spectacle independence rate.

Objective To discuss comfort nursing effect for rehabilitation exercise compliance of hip replacement patients. Methods 76 cases of senile hip replacement patients were retrospecrively analyzed and divided into the control group and the research group with 38 cases in each group, each received rourine nursing and comfort nursing. The nursing effect was compared between two groups. Results The research group was better in nursing satisfaction degree, comfort degree, complications such as infection and prosthesis dislocation and recovery exercise compliance compared with those of the control group. Conclusions Comfort nursing has considered patients' requirement and aiming to these requirements. So it can help patients to elevate the comfort degree, improve prognosis and satisfaction degree.

ObjectiveTo explore the influence of L-carnitine on the effect of erythropoietin in treatment of patients with renal anemia during hemodialysis treatment.Methods40 uremic patients with chronic renal failure underwent bemodialysis(HD) in were randomly divided into treatment group and control group,20 cases each.Control group was given EPO 9000u/week subcutaneous injection in the blood after dialysis,while regular oral iron,folic acid.Treatment group on the basis of the control group to 1.0g L-carnitine added 20ml 0.9％ sodium chloride injection intravenously 3 ～ 5 min,2 times per week.Both groups were treated for 3 months.Before treatment and after 4 weeks and 3 months treatment.The hemoglobin(Hb),hematocrit (Hct),serum ferritin (SF),serum thyroxine(iPHT) and compared.ResultsAfter 4 weeks of treatment,Hb,Hct levels increased compared with before treatment( all P ＜0.05).Hb after 3 months compared with the two groups before treatment were significantly higher(all P ＜0.05),and Hb increase of the treatment group significantly higher than the control group ( P ＜ 0.01).ConclusionL-carnitine could improve the treatment of erythropoietin in hemodialysis patients with renal anemia.

Objective To analyze the pathogens distribution and drug resistance in acute stroke with stroke associated pneumonia (SAP) patients,and provide references for proper clinical application of antibiotics.Methods A retrospective investigation was performed to analyze the pathogens and the drug resistance of 131 acute stroke with SAP patients.Results Among 148 strains of isolated pathogens,the Gram-negative bacteria accounted for 66.22％ (98/148),including Klebsiella pneumoniae,Pseudomonas aeruginosa,Escherichia coli,Acinetobacter baumannii,Enterobacter cloacae and so on.Gram-positive bacteria accounted for 26.35％ (38/148).Staphylococcus aureus ranked the first,followed by Coagulase negative staphylococcus and Enterococcus faecalis.Fungi accounted for 7.43％ (12/148),mainly including Candida albicans.They had varying degrees of resistance to commonly used antibiotics.Conclusions Gram-negative bacteria are predominant in SAP.Drug resistance is very serious,and the antibiotics should be selected in clinic according to the result of drug susceptibility test.

Objective To explore the effects of focused settlement mode applied in caring the acute paraquat poisoning patients.Methods 106 hospitalized patients with acute paraquat poisoning were randomly divided into the control group and the experimental group.All patients in the control group were performed conventional nursing instruction and the experimental group was nursed with focused settlement mode on the basis of conventional nursing instruction.The efficacy of nursing was evaluated when they were discharged from hospital.Results The self-care skills and knowledge,consciously following the medical behavior,satisfaction degree with clinical service of the experimental group were significandy better than the control group,while the hospitalization days were shorter than the control group.Conclusions Focused settlement mode can improve the effect of nursing care for patients with acute paraquat poisoning.
