Treatment of Connective Tissue Diseases-associated Interstitial Lung Disease by the Origin-restoring and Bi （痹）-alleviating Method / 中医杂志

It is believed that the fundamental pathogenesis of the connective tissue diseases-associated interstitial lung disease （CTD-ILD） is kidney essence deficiency， with lung collateral obstruction throughout the disease， and environmental toxin pathogen is the important causative factors for the development of CTD-ILD. This article proposed to restore origin and alleviate bi （痹） for CTD-ILD， for which restoring origin means tonifying the lungs， spleen and kidneys to bank up the roots and consolidate the original qi， with modified Erxian Decoction （二仙汤） plus Liu Junzi Decoction （六君子汤）； alleviating bi means expelling wind and dredging collaterals， and eliminating the mass to restore the smoothness of the lung collaterals， with paired medicines of Chuanshanlong （Dioscorea nipponica）-Dilong （Kalanchoe pinnata）， Vinegar-processed Sanleng （Sparganium stoloniferum）-Vinegar-processed Ezhu （Curcuma zedoaria）， and stem-type medicines， and emphasized on removing the environmental toxin pathogens to facilitate the recovery of healthy qi.

Construction of seamless genome editing system for fast-growing Vibrio natriegens / 生物工程学报

Recently, fast-growing Vibrio natriegens, as the great potential chassis, has shown a wide application in synthetic biology. Genome editing is an indispensable tool for genetic modification in synthetic biology. However, genome editing tools with high efficiency and fidelity are still to be developed for V. natriegens synthetic biology. To deal with this problem, the physiological characteristics of 6 V. natriegens strains were evaluated, and CICC 10908 strain with fast and stable growth was selected as the host strain for genome editing study. Then, the natural transformation system of V. natriegens was established and optimized. The efficiencies of optimized natural transformation that integrates antibiotic resistance marker cat-sacB or Kan(R) onto the chromosome of V. natriegens could reach 4×10⁻⁵ and 4×10⁻⁴, respectively. Based on the optimized natural transformation, a double-selection cassette was used to achieve seamless genome editing with high efficiency and fidelity. The positive rates of four different types of genetic manipulation, including gene deletion, complementation, insertion and substitution, were 93.8%, 100%, 95.7% and 100%, respectively. Finally, transformation and elimination of the recombinant plasmid could be easily achieved in V. natriegens. This work provides a seamless genome editing system with high efficiency and fidelity for V. natriegens synthetic biology.

Analyze 11425 cases of congenital malformations for birth defects intervention / 实用医学杂志

Objective To collect the incidence and distribution of congenital malformations ,find monitor-ing and preventive measures,to provide a basis for reasonable allocation of health resources for clinical depart-ments. Methods According to The International Classification of Diseases(ICD-10)chapter 17 encoding table, we analyze our hospital′s cases from January 2003 to December 2010 in order to understand the incidence of con-genital malformations of every system. Results Top five diseases are:cleft palate deformity ,genital malforma-tion,congenital heart disease and digestive system malformation in equal third place,and facial deformity. The age ranged from 1d to 35 y,men more than women. Conclusions The key to effectively reduce the incidence of con-genital malformation is strictly implement the three-level intervention mechanism. Prevention ,early detection and early treatment will improve the patient′s quality of life.

Distribution and antimicrobial resistance of coagulase-negative staphylococci isolated from cerebrospinal fluids in neurosurgical patients / 中华临床感染病杂志

Objective To investigate the distribution and antimicrobial resistance of Coagulase-negative staphylococci ( CoNS) isolated from cerebrospinal fluids in neurosurgical patients.Methods CoNS strains isolated from cerebrospinal fluids of neurosurgical patients were collected from Beijing Tiantan Hospital of Capital Medical University during January 2013 and December 2015.CoNS infection was diagnosed according to the standards of US Centers for Disease Control and Prevention, and the distribution and antimicrobial resistance of pathogenic CoNS strains were analyzed. Results A total of 19 756 cerebrospinal fluid specimens were collected and 1 386 bacterial strains were isolated, in which 650 (46.9%) were CoNS.Among 650 CoNS strains, 130 were diagnosed as the pathogen, and the top 4 CoNS species were Staphylococcus epidermidis (77/130, 59.2%), Staphylococcus hominis (18/130, 13.8%), Staphylococcus haemolyticus (11/130, 8.5%) and Staphylococcus capitis (9/130, 6.9%).The rest 520 CoNS strains were contaminating strains.According to antimicrobial susceptibility test, there were 103 strains of methicillin-resistant CoNS (MR-CoNS) accounting for 79.1% (103/130).And among 77 Staphylococcus epidermidis isolates, 67 were MR-CoNS strains (87.0%) .More than 90.0%Staphylococcus epidermidis isolates were sensitive to vancomycin and linezolid, and the rest CoNS strains were also highly sensitive to these two antibacterial agents.Conclusions CoNS plays an important role in post-surgery infection in neurosurgical patients, and Staphylococcus epidermidis is the dominant CoNS species.Most CoNS strains are methicillin-resistant, but are highly sensitive to vancomycin and linezolid.

Correlations between emotions and self-concept in patients with traumatic brain injury / 现代临床护理

Objective To explore the correlations between emotions and self-concept in patients with traumatic brain injury. Method The Chinese version of the Positive and Negative Affect Scale and the Tennessee Self-Concept Scale was used to test 178 patients with traumatic brain injury.Results The mean scores on positive and negative emotions were (1.93±0.53) and (2.76±0.61), respectively. The mean score on self-concept was (2.45±0.31). The positive emotions of patients were positively correlated with the level of self-concept and the negative emotions negatively with the level of self-concept (r=0.437and -0.363respectively,bothP<0.01). Conclusions For patients with traumatic brain injury,the negative emotions outnumber the positive emotions and their self-concept was at lower level. Nurses should take measures to improve their positive emotions and reduce their negative emotions in order to improve their self-concept level.
