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.

Breast milk is the normative standard for infant nutrition and contains a wide variety of proteins that contribute to its unique qualities.Bile salt-stimulated lipase and amylase assist in the digestion and utilization of micronutrients and macronutrients from the milk.Several proteins with antimicrobial activity,such as immunoglobulins,lactoferrin,k-casein,lysozyme and lactoperoxidase,are relatively resistant against proteolysis in the gastrointestinal tract and may,in intact or partially digested form,contribute to the defense of breastfed infants against pathogenic bacteria and viruses.Cytokines,colony stimulating factor and chemokine have immunomodulatory activities,whereas insulin-like growth factor,epidermal growth factor and peptides from caseins are likely to be involved in the development of the intestinal mucosa and other organs of newborns.In combination,breast-milk proteins assist in providing adequate nutrition to breastfed infants while simultaneously aiding in the defense against infection and facilitating optimal development of important physiologic functions in newborns.

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.
