RESUMO
Objective To explore the difference of balance ability between patients with chronic nonspecific low back pain ( CNLBP) and healthy individuals, and the correlation between patients’ pain symptoms, lumbar flexibility, abdominal muscle endurance, overall function, quality of life and fear of avoidance with balance ability, so as to guide clinical rehabilitation evaluation. Methods A total of 34 patients with CNLBP were selected as the experimental group, and 34 healthy volunteers without history of low back pain were selected as control group. The plantar pressure measurement system was used to collect the ratio of forefoot to hindfoot pressure, pathlength ( L) of plantar center of pressure ( COP), displacement length in anteroposterior direction ( LAP ), displacement length in mediolateral direction (LML ), mean velocity (v), displacement velocity in anteroposterior direction (vAP ), displacement velocity in mediolateral direction (V-ML) and elliptical swing area (S). In addition,the experimental group was assessed by the visual analogue scale (VAS), the finger floor distance (FFD), the number of sit-ups in 1 minute, the Oswestry disability index (ODI), the 36-item short form survey (SF-36) and the fear avoidance beliefs questionnaire (FABQ), and correlated with plantar pressure parameters. Results All plantar pressure parameters were significantly different between the two groups ( P < 0. 05). The the ratio of forefoot to hindfoot pressure in experimental group was significantly lower than that in control group (P<0. 05), and the parameters L, LAP , LML , v, vAP , vML and S were significantly higher than those of control group (P<0. 05). With eyes open or closed, the VAS score of experimental group was positively correlated with L, LAP , LML(P<0. 05), and FFD and FABQ scores were positively correlated with L and LML , respectively (P< 0. 05). With eyes open, ODI was positively correlated with L, LAP and LML (P< 0. 05), and SF-36 score was negatively correlated with L and LML(P<0. 05). With eyes closed, the number of 1-min sit-ups was negatively correlated with LAP and S (P<0. 05), ODI was positively correlated with L and LML(P<0. 05), and the SF-36 score was negatively correlated with L (P<0. 05). Conclusions The static balance ability of patients with CNLBP is decreased, and it is correlated with pain symptoms, lumbar function, quality of life and psychological status. The result can provide references for the assessment of functional activities.
RESUMO
With the appearance of direct-acting antivirals (DAAs), breakthroughs have been achieved in the antiviral therapy for hepatitis C and hepatitis C patients can be cured completely. Due to the insidious onset of hepatitis C, most patients do not know their own conditions, and thus expanding diagnosis and treatment through screening is the key to the elimination of hepatitis C. However, hepatitis C virus is distributed widely and unevenly in the world, which results in difficulties in the screening and diagnosis of hepatitis C. This article introduces the current economic research on hepatitis C screening, analyzes the factors affecting the cost-effectiveness of hepatitis C screening, and shares the strategies and advances for hepatitis C elimination in other countries, so as to provide a reference for eliminating hepatitis C in China.

After the treatment, the rate of removal of varicose veins, the rate of rebleeding, the number of total treatment,mortality and intra-operative complications and postoperative complications were compared. And compared rebleeding rate and mortality with the control group and study groups with different CTP and MELD, analyze the factors of prognosis, and evaluate their prognostic value.Results Rebleeding, rate in control group, EVL group and sequential group were 41.51%,10.53% and 10.64%,sequential group was significantly better than control group (P = 0.000); mortality in control group, EVL group and sequential group were 15.09%, 5.26% and 2.13%, sequential group was also significantly better than control group (P = 0.001); rate of recurrence in EVL group and sequential group within half a year were 73.68% and 44.68%, sequential group was significantly better than EVL group (P = 0.021). In all control group and EVL group and the sequential group, rebleeding rate and mortality of the liver function Child-Turcotte-Pugh (CTP) class C was significantly higher than that of calss A; In MELD model, AUC area under the ROC curve of rebleeding rate in control group and sequential group were 0.944 and 0.851, mortality of the two groups were 0.881 and 0.984, while the rate of recurrence in the EVL group and sequential group were respectively 0.914 and 0.765, the MELD score has the important value to the prediction of rebleeding and death.Conclusion The rebleeding rate and mortality in cirrhotic patients with esophageal varices treated with sequential endoscopic variceal ligation plus endoscopic variceal sclerotheropy were significantly decreased and the recurrence rate was lower than that of the patients with endoscopic variceal ligation all the time. Liver function Child-Turcotte-Pugh (CTP) score and the MELD score have important value in prediction of rebleeding and death, ligation and sclerosing sequential therapy can significantly reduced rebleeding and mortality in CTP class B and C, and improve the MELD threshold of rebleeding and death.
RESUMO
Objective To evaluate the feeding effect of semi-demand feeding and abdominal massage on the feeding process, feeding performances and clinical safety (including the time of returning to birth weight, feeding tolerance, apnea). Methods A total of 120 preterm infants that met inclusion criteria of the study were randomly assigned to three groups, and each group had 40 cases. Control group:received standard feeding care. Semi-demand feeding group: received 5-10 minutes of oral motor intervention every time before feeding(including oral stimulation and non nutritional sucking), then decided feeding methods according to its consciousness behavior state. Semi-demand feeding combined abdominal massage group: received both semi-demand feeding and abdominal massage before feeding. Observed and recorded the three groups′ transition time, whether there were statistically significant differences in feeding performance and clinical safety. Results The feeding transition time was (11.55± 4.69), (10.98±3.85), (8.50±3.87)d in control group, semi-demand feeding group and semi-demand feeding combined abdominal massage group, and there were significant differences (F=6.088, P=0.003). In terms of feeding performance, the feeding efficiency were (7.27 ± 2.65), (9.74 ± 2.63), (9.52 ± 2.13) ml/min, the feeding proficiency were (66.31 ± 14.51)%, (76.64 ± 12.46)%, (82.26 ± 10.65)%, the volume transfer were (63.99 ± 11.02)%, (80.16 ± 14.41)%, (84.97 ± 11.16)% in control group, semi-demand feeding group and semi-demand feeding combined abdominal massage group, and there were significant differences (F=12.189, 16.383, 31.959, all P < 0.01).Among the clinical safety, the time of restoration of birth weight were (10.55 ± 1.99), (9.28 ± 1.77), (10.05 ± 2.46) d in control group, semi-demand feeding group and semi-demand feeding combined abdominal massage group, and there were significant differences(F=3.759, P=0.026). The incidence of feeding intolerance were 50.0%(20/40), 40.0%(16/40), 22.5%(9/40), and there were significant differences(χ2=6.613, P=0.037). The incidence of apnea were 37.5%(15/40), 20.0%(8/40), 15.0%(6/40), and there were significant differences(χ2=6.093, P=0.048). Conclusions The combined intervention methods could accelerate the feeding process, improve feeding performance as well as reduce the incidence of feeding intolerance and apnea. Hence, semi-demand feeding combined abdominal massage is a recommended choice for clinical use.
RESUMO
Breast milk, whether the ratio of nutritional ingredients or immunological characteristics, were the most suitable for physiological needs of preterm infants. However, breast milk composition was in dynamic change, causing imbalance of energy, which could not make the premature infant to achieve the desired growth state. Human milk fortifier, retaining advantages of the breast milk, promoted growth of premature infants further. This review primarily focused on two ways of adding human milk fortifiers, standardization fortification and targeted fortification. The former was widely used in neonatal intensive care unit, while the latter was more able to explore the growth of premature infant potentially, and to achieve a more ideal ectopic growth rate. With the development of breast milk bank, storage and component extraction technology brought about donor human milk-based human milk fortifier, which provided new directions of very low birth weight infants and very preterm infants breastfeeding. The progress of human milk fortification of premature infants was closely related to expansion of multi-disciplinary centers, and only the harmonious development of multi-center maked things much more rational and systematic.
RESUMO
Objective To investigate the level and influencing factors of stigma among patients with lung cancer, in order to provide evidence for staff nurses to take pertinent interventions for assisting patients to deal with stigma. Methods Totally 234 hospitalized patients with lung cancer were cross-sectional survey with General Demographic Questionnaire, Disease Information Questionnaire, Chinese version of Cataldo Lung Cancer Stigma Scale (CLCSS-CV). Results The total score of stigma was (72.35±10.85) points. The total scale score and each subscale score was divided by the item number. The mean score of CLCSS-CV was (2.68±0.40) points, the rate of the patients with lung cancer with moderate above stigma was 51.20% (120/234). The patients rated higher scores on the subscales of smoking (2.90±0.58) points, while lower scores on the subscales of discrimination (2.47 ±0.55) points. Multiple stepwise regression analysis showed that the number of children and the clinical stages were influencing factors of lung cancer stigma, where regression coefficients were -0.065, 0.136 respectively, coefficients of determination was 0.178. Conclusions Patients with lung cancer have a moderate or higher level of stigma. The medical staff should communicate with patients, evaluate the psychological status, impose public health education, mobilize the social support for assisting them to deal with stigma.

Objective To observe the effects ofJingui Shenqi Pills on the expressions of TGF-β1, CYP19, sex hormone level and sperm quality;To discuss its mechanism for the treatment of male sterility.Methods Forty adult male SD rats were randomly divided into normal group, model group, retardant group andJingui Shenqi Pills group, 10 rats in each group. Except for the normal group, adenine was used to induce healthy rats to kidney yang deficiency and sterility model rats. Normal group was given normal saline for gavage;retardant group was injected with testicular mesenchyme TGF-β1;Jingui Shenqi Pills group was givenJingui Shenqi Decoction for gavage. Blood was taken through caudal vein. Immunohistochemical, radioimmunoassay and electron microscopy observation were used to detect the expressions of TGF-β1, CYP19, sex hormone level, sperm density and motility rate and testicular morphological changes.Results Compared with normal group, the expression of TGF-β1 in the model group increased and CYP19 decreased (P<0.05). Compared with model group, the expression of TGF-β1 decreased and the expression of CYP19 increased (P<0.05). Compared with normal group, the number of sperm quantity was small and paramorphia in model group (P<0.05). Compared with model group, T, E2, sperm density and motility rate increased significantly inJingui Shenqi Pills group and retardant group (P<0.05). There was no statistical significance among indexes in retardant group andJingui Shenqi Pills group.ConclusionJingui Shenqi Pills can improve sperm quality and sex hormone level of model rats with kidney-yang-deficiency, which mechanism is probably realized by inhibiting the expression of TGF-β1R and promoting the expression of CYP19 in testis to effect development and proliferation of sperm.
