Objective To introduce a self- assembled adjustable traction frame for the patients with severe trauma and lower limb fracture in ICU, compared with Brawns traction frame. Methods 96 patients with severe trauma and lower limb fracture diagnosed by clinical signs and X-ray who had to be transferred to ICU were randomly divided into the study group (46 cases) and the control group (50 cases) by sealing letters method.The study group were tracted by the self-assembled adjustable traction frame, and the control group were tracted by the Brawns traction frame. The fracture alignment, degree of pain, incidence of pressure ulcers, nursing limit time of changing the sheets of the two groups were observed. Results The results declared that 37 cases with 2 pain score points, 9 cases with 0-1 points in the study group and 19 cases with 2 pain score points, 3 cases with 0-1 points, 28 cases with Grade 3 in the control group (χ2=38.683, P<0.01). In the control group, pressure ulcer were occurred, 5 of them at Level one, 1 of them at Level two, 1 of them at Level three and the incidence rate was 14.00% (7/50). In the study group, pressure ulcer were occurred, 1 of them at Level two and the incidence rate was 2.17%(1/46). The pain level and incidence of pressure sore in the study group were decreased and the difference between the two groups was significant (χ2=8.197, P < 0.05). Conclusions The self-assembly adjustable traction rack can not only ensure the same effect as the Brawns traction frame but also reduce the deficiency caused by Brown traction frame. It is safer and more comfortable for the patients and can reduce nursing complications and improve the quality and efficiency of the nursing work.

Objective:To explore the inhibition of microRNA (miRNA, miR)-5590-3p on the expression of transforming growth factor beta typeⅡreceptor (TGFBR2) gene and its effect on the invasion and proliferation of gastric cancer cell line HS-746T.Methods:The gastric cancer cell line was cultured in vitro. Real-time quantitative polymerase chain reaction (qRT-PCR) was used to analyze the expression of miR-5590-3p in gastric cancer tissues and cell lines. The miR-NC and miR-5590-3p mimic were transfected into gastric cancer cell line HS-746T by lipofection, and named as miR-NC group and miR-5590-3p group, respectively. qRT-PCR was used to measure transfection effects. Transwell assay and cell counting kit-8 (CCK-8) assay were used to detect cell invasion and proliferation after transfection. The bioinformatics software predicts and the dual luciferase reporter gene system validates the target gene of miR-5590-3p. qRT-PCR and western blot were used to measure the expression of TGFBR2 and its downstream proteins in the transfected cells. Results:The expression of miR-5590-3p in gastric cancer tissues was significantly lower than that in adjacent tissues ( P<0.01). The expression of miR-5590-3p in gastric cancer cell lines was significantly lower than that in normal gastric mucosal epithelial cells ( P<0.05), and lowest in HS-746T cells ( P<0.01). After transfection, the expression of miR-5590-3p in miR-5590-3p group (11.76±0.21) was significantly higher than that in miR-NC group (1.06±0.21), with statistically significant difference ( P<0.01). The number of invasive cells in miR-NC group and miR-5590-3p group were (101.20±15.47) and (26.53±6.53), respectively, and the invasion ability of miR-5590-3p group was significantly decreased ( P<0.01). Compared with the miR-NC group, the cell proliferation ability of the miR-5590-3p group was significantly decreased ( P<0.05). Bioinformatics software showed that the target gene for miR-5590-3p is TGFBR2. The dual luciferase reporter gene system confirmed that miR-5590-3p can target the TGFBR2 gene ( P<0.01). Western blot results showed that compared with miR-NC group, the expression of TGFBR2 in HS-746T cells in miR-5590-3p group was significantly decreased ( P<0.01), the expression of ZEB-1 and ZEB-2, and the expression of CDK1 and cyclin B proteins were decreased as well. Conclusions:miR-5590-3p can inhibit the invasion and proliferation of gastric cancer cell HS-746T by targeting and regulating the expression of TGFBR2 gene.

ObjectiveTo investigate the effect of acupuncture on motor function and serum expressions of TNF-aand IL-6 contents in cerebral hemorrhage rats.MethodSeventy-two male Wistar rats were randomized into sham operation, model and acupuncture groups. A rat model of cerebral hemorrhage was made by intracerebral injection of autoblood. Baihui-to-Qubin acupuncture was performed after successful model making. The TNF-aand IL-6 contents of rat serum were measured by enzyme linked immunosorbent assay at three time points: one, three and seven days.ResultBaihui-to-Qubin acupuncture markedly increased the neurological function score and reduced neurologic deficits in cerebral hemorrhage rats. At the same time point, serum TNF-aand IL-6 contents were significantly lower in the acupuncture group of rats thanin the model and acupuncture group; there were statistically significant differences (P<0.01).ConclusionBaihui-to-Qubin acupuncture can reduce neurologic deficits in cerebral hemorrhage rats. It may be related to decreases in serum TNF-aand IL-6 contents after acupuncture.

Objeetive To analyze the clinicopathologic features of proliferative sclerosing IgA nephropathy and the efficacy of prednisone therapy.Methods A retrospective analysis was conducted,enrolling 50 patients with biopsy-proven primary proliferative sclerosing IgA nephropathy who were admitted in the Hospital from January 2005 to June 2015-26 males and 24 females,mean age (36.8 ± 10.4) years.Clinicopathologic features and prednisone therapeutic effect were analyzed.Results The clinical manifestations of 50 cases were nephritis syndrome with varying degrees of renal insufficiency,including 32 cases (64.0％) with hypertension,15 cases (30.0％) with microscopic hematuria.Renal biopsy showed the incidence of glomerular global sclerosis was 17.0％-47.2％,tubular atrophy/ interstitial fibrosis outstanding (T0 50％,T1 32％,T2 18％).After prednisone treatment,compared with sustained remission group and relapse group,invalid patients had higher incidence of hypertension (P ＜ 0.05),relatively lower Hb (P ＜ 0.01) and serum albumin,more significant renal dysfunction (P ＜ 0.01),more severe glomerular global sclerosis,segmental sclerosis,tubular atrophy/ interstitial fibrosis,while the lower interstitial inflammatory cell infiltration.During the follow-up,which lasted from 6 to 132 months (median 27.3 months),the effective rate of treatment was 74.0％ after sufficient prednisone or half dose prednisone therapy.Repeated recurrence rate was 32.0％.At the end of the follow-up period,13(26.0％) patients entered the stage of uremia.Conclusions Application of glucocorticoids in the treatment of proliferative sclerosing IgA nephropathy can protect renal function and delay the progression of renal impairment.The efficacy of glucocorticoids therapy is significantly associated with the presence or absence of hypertension,the degree of renal function impairment,and the severity of the onset of renal pathology.

Coxsackievirns A16(CVA16),together with enterovirus type 71(EV71),is responsible for most cases of hand,foot and mouth disease(HFMD) worldwide.Recent findings suggest that the recombination between CVA16 and EV71,and the co-circulation of these two viruses may have contributed to the increase of HFMD cases in China over the past few years.It is therefore important to further understand the virology,epidemlology,virus-host interactions and host pathogeuesis of CVA16.In this study,we describe the viral kinetics of CVAI6 in human rhabdomyosarcoma(RD) cells by analyzing the cytopathic effect(CPE),viral RNA replication,viral protein expression,viral RNA package and viral particle secretion in RD cells.We show that CVA16 appears to first attach,uncoat and enter into the host cell after adsorption for 1 h.Later on,CVA16 undergoes rapid replication from 3 to 6 h at MOI 1 and until 9 h at MOI 0.1.At MOI 0.1,CVA16 initiates a secondary infection as the virions were secreted before 9 h p.i.CPE was observed after 12 h p.i.,and viral antigen was first detected at 6 h p.i.at MOI 1 and at 9 h p.i.at MOI 0.1.Thus,our study provides important information for further investigation of CVA16 in order to better understand and ultimately control infections with this virus.

Objective To investigate the feasibility, effect and mechanism of chemical bile duct embolization for chemical hepatectomy. Methods Phenol or absolute ethanol plus cyanonacrylate were employed as embolization agents. Histology, Fas and TGF-? 1 measurement were used to evaluate the result. Results Phenol plus cyanonacrylate effectively destroyed and embolized intrahepatic biliary duct, leading to complete disappearance of hepatocytes in the periphery of embolization lobe and thereby achieving the effect of chemical hepatectomy. Expression of Fas and TGF-? 1 in phenol embolism group (88.90?38.10, 185.22?70.39) and ethanol embolism group (72.39?29.51, 163.56?51.75) were higher than those in biliary duct ligated group (26.31?12.07, 74.84?40.73) ( P

Objective The action mechanisms of Qingfei Oral Liquid ( QFOL) in the treatment of respiratory syncytial virus ( RSV) infection need to be studied more deeply.The aim of this study is to examine the expressions of interleukin ( IL)-10 and IL-17 in the lung tissue and those of Treg and Th17 in the spleen tissue of RSV-infected mice before and after treated with QFOL, and to explore the action mechanisms of QFOL from the perspective of the Treg/Th17 cy-tokines balance. Methods Fifty BABL/c mice were equally ran-domized to five groups: blank control, RSV model, Ribavirin, low-dose QFOL, and high-dose QFOL.Models of RSV ( long strain) infec-tion were made in the latter four groups.At 48 hours after viral activa-tion, the mice of the control and RSV model groups were treated intragastrically with 0.9%normal saline and those in the Ribavirin and QFOL groups with Ribavirin at 0.0025 g/mL and QFOL at 1.33 g/mL and 4 g/mL, respectively, all for 72 hours.Then all the mice were killed and the lung tissue harvested from 5 animals in each group for pathological analysis, while the levels of IL-10 and IL-17 in the bronchoalveolar lavage fluid of the other 5 detected by ELISA.The expressions of the cytokines Treg and Th17′in the spleen from 4 mice in each group were determined by flow cytometry. Results Compared with the RSV models, pathologic changes were significantly re-duced in the mice of the QFOL, Ribavirin and control groups (P<0.01), the expression of IL-10 remarkably up-regulated in the low-dose QFOL, high-dose QFOL, Ribavirin, and control groups ([39.21 ±1.57] vs [43.54 ±1.03], [46.64 ±0.48], [47.83 ±0.87], and [50.44 ±1.04] ng/L, all P<0.01), while the level of IL-17 markedly down-regulated ([70.96 ±0.53] vs [55.92 ±0.83], [33.66 ±0.70], [21.92 ±1.38], and [9.42 ±0.59] pg/mL, all P<0.01).The expressions of Treg/Th17′were significantly in-creased in the low-dose QFOL, high-dose QFOL, Ribavirin, and control groups (2.89 ±0.52, 6.38 ±0.36, 3.95 ±0.26, and 3.54 ± 0.85) as compared with that in the RSV models (0.96 ±0.16) (all P<0.01).Both low-and high-dose QFOL groups showed statisti-cally significant differences from the Ribavirin group in the levels of Treg, Th17, and Treg/Th17 (P<0.05). Conclusion QFOL can regulate the balance of Treg/Th17, increase the expression of IL-10 and decrease that of IL-17 in the lung tissue of RSV-infected mice, which further proves the efficacy of QFOL in the treatment of RSV-induced pneumonia.
