She is good at use of insect medicine to seize the meridians, and focuses on comprehensive care, which provides positive reference value for TCM treatment of IMN.

It has been confirmed that circulating tumor cells (CTCs) may be the origin of a wide variety of tumor metastasis,which plays an important rote in tumor metastasis,recurrence and treatment-resistant.Through the enrichment detection and analysis of biological characteristics of CTCs,useful information can be provided for the early diagnosis of tumor,assessment of metastasis risk and prognosis,as well as individualized anti-tumor treatment project.In this paper,the research progress on detection of CTCs and its clinical application were reviewed in recent years.

BACKGROUND:In addition to infection, the reasons for total knee arthroplasty revision are polyethylene liner wear and prosthesis loosening. The impact of joint line height on patelofemoral biomechanics was inconclusive. OBJECTIVE: To study the impact of joint line changes after total knee arthroplasty on patelofemoral joint biomechanics. METHODS: Three-dimensional finite element models were established after total knee arthroplasty. The impact of different joint line height on quadriceps tensile force, patela tendon tension, and patelofemoral joint forces was calculated at range of flexion of 0°, 30°, 60° and 90°. RESULTS AND CONCLUSION: (1) At knee flexion of 0°, the height of the joint line in-3 mm-4.5 mm did not have great impacts on quadriceps tensile force, patela tendon tension and patelofemoral joint forces. (2) At knee flexion of 30°-90°, the height of the joint line below 3 mm did not have great impacts on quadriceps tensile force, patela tendon tension and patelofemoral joint forces. The height of the joint line more than 3 mm had obvious impacts on quadriceps tensile force, patela tendon tension and patelofemoral joint forces. (3) It was recommended that the height of joint line in total knee arthroplasty was preferably controled within 3 mm.

To analyze the significance of intraocular scattered light and contrast sensitivity in cataract patient's visual quality.METHODS: Seventy-three cases of cataract patients ( 120 eyes ) in our department from January 2012 to January 2014 were selected, of which 32 cases (52 eyes) were cortical cataract, 18 cases ( 33 eyes ) were nuclear cataract, 23 cases ( 35 eyes ) were posterior subcapsular cataract, and 40 normal persons ( 40 eyes ) were as the normal group. The full-eye corneal astigmatism and total astigmatism were observed in all those enrolled. The contrast sensitivity of different perspective was checked by automatic glare contrast sensitivity tester.RESULTS: The corneal astigmatism and full eye total astigmatism in the cortical cataract group, nuclear cataract group and the posterior capsule cataract group was significantly higher than that in the normal group( P<0. 05). The total astigmatism was no significant difference cataract in three groups of patients with corneal astigmatism and total full eye astigmatism (P>0. 05). The contrast sensitivity in the cortical cataract group, nuclear cataract group and posterior subcapsular cataract group in the whole band were significantly lower than the normal group (P<0. 05). The contrast sensitivity of posterior subcapsular cataract group in the whole band was significantly lower than cortical cataract groups and nuclear cataract group(P<0. 05).CONCLUSlON: lntraocular scatter light and contrast sensitivity joint inspection can effectively evaluate the visual quality of cataract patients, which lead to early treatment.

Objective: To investigate the relationship between nutritional status and body fluid distribution in continuous ambulatory peritoneal dialysis (CAPD) patients. Methods: Sixty-six CAPD patients without edema were recruited in this study. Patients’ fluid status was measured by bioimpedance analysis (BIA) and nutritional status was assessed by subjective global assessment (SGA). Thirty-six age-matched healthy people served as controls. Results: As compared to the healthy control, CAPD patients had significant abnormal fluid distribution in the body with significantly decreased intracellular water (ICW) and little change in extracellular water (ECW). Malnutrition further aggregated the changes in body fluid distribution. Conclusion: Body fluid distribution is abnormal in CAPD patients and may be affected by patients’ nutritional status. The ratio of ICW/ECW can not be correctly used to evaluate hydration state when the patient is malnourished. Key word: intracellular water (ICW); extracellular water (ECW); bioimpedance analysis (BIA); malnutrition

Objective:To improve hypertension management in peritoneal dialysis patients through CQI process. Methods: Using the 4 step problem solving framework called the PDCA cycle-plan, do, check and act, we conducted a CQI program. Results: One hundred and forty five peritoneal dialysis patients dialyzed for more than 3 months participated in the study. In 49 prevalent patients, the incidence of uncontrolled hypertension (BP≥140/90 mm Hg, 1 mm Hg=0.133 kPa) decreased from 49% to 16.3% although there were no significant changes in antihypertensive medication and total fluid removal. The incidence of uncontrolled hypertension in incident patients decreased from 61.3% to 28%. Height normalized extracellular water decreased significantly. In males it was from (10.8?1.4) kg/m to (10.3? 1.7) kg/m and in females (9.6?1.2) kg/m to (8.6?1.2) kg/m. Conclusion:CQI is a useful method in the management of hypertension in peritoneal dialysis patients.
