The incidence of gastric retention, abdominal distension and vomiting in the intervention group was lower than that in the control group, but only the difference in the incidence of gastric retention (24.4％ vs 47.5％) was statistically significant (P<0.05). The incidence of feeding intolerance was significantly lower in the intervention group than in the control group (24.39％ vs 47.50％, P<0.05). Conclusion Comprehensive nursing intervention can shorten the tube feeding time of premature infants, promote the weight growth of premature infants, improve the feeding quality, reduce the incidence of feeding intolerance, and reduce the hospital stay of premature infants, so as to reduce the hospitalization cost, improve the quality of life of premature infants, and increase the satisfaction of parents.
ABSTRACT
Circular RNAs (circRNAs) are a class of non-coding RNAs with covalently closed continuous loops. Owing to its specific molecular structure, circRNA is conserved and stable in vivo. Recently, the circRNAs have received extensive attention in the treatment of cancers including breast cancer. Notably, the recent evidence has demonstrated that circRNAs are aberrantly expressed in plasma and tumor tissues of breast cancer patients, and the expressions of those circRNAs in different subtypes of breast cancer were also heterogeneous. The abnormally expressed circRNAs are able to regulate the expression of cancer-related genes by binding their targeting microRNAs and other biomolecules to inhibit their functions. Moreover, the circRNAs are also considered as important players in the proliferation, invasion and apoptosis of breast cancer cells, as well as the treatment toxicities and drug-resistance. This paper reviews the biological characteristics and functional roles of cancer-related circRNAs, especially the current research on their association with occurrence, progression and drug-resistance of breast cancer.
ABSTRACT
To compare the effect of cold or room temperature of tumescence anesthesia solution on pain perception during and after endovenous laser ablation (EVLA) for varicose veins of lower limb. Methods: A total of 51 patients with lower extremity varicose vein were treated by EVLA with tumescence anesthesia solution. All patients were used for local anesthesia and randomly divided into 2 groups according to the temperature of tumescence anesthesia solution: Group A (n=26) with room temperature (24 ℃) of tumescence anesthesia solution and Group B (n=25) with cold (4 ℃) tumescence anesthesia solution. Number rating scale (NRS) was recorded immediately after the procedure and postoperative 1, 2, 3 day. Patients were asked to register pain scores during the week. Results: The mean linear endovenous energy density (LEED) in the 2 groups was not significantly different (P>0.05). The ratio of patients without pain during the operation in the Group A was lower than that in the Group B (30.8% vs 64%, P<0.05). On the day of operation and postoperative day 1, 2, 3, the average number rating scale (NRS) scores in the Group A were greater than those in the Group B (P<0.05). Postoperative day 1, only 30.8% of the patients in the Group A resumed daily activities, which was lower than that (68% of the patients) in the Group B. Conclusion: In the process of EVLA for varicose veins of lower limb, there is less pain during operation and post-operation using cold tumescence anesthesia solution comparing room temperature tumescence anesthesia solution.

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.
ABSTRACT
Purpose To investigate the application value in diagnosis of pleural effusion by cell block combined with immunohisto-chemistry. Methods 60 cases of pleural effusion were collected, and paraffin-embedded cell block was prepared and immunohisto-chemistry was used to detect the expression of CK7, TTF-1, E-cadherin, CEA and Calretinin. Results By use of cell block combined with immunohistochemistry, malignant detected rate was higher than that of the conventional centrifugal smear. There was statistical significance in the expression of CK7, TTF-1, E-cadherin, CEA and Calretinin between pleural effusion lung adenocarcinoma and reac-tive hyperplasia mesothelial cells (P<0. 05). CK7, TTF-1, E-cadherin and CEA were highly expressed in pleural effusion of lung ad-enocarcinoma cell. Calretinin was highly expressed in hyperplastic mesothelial cells. Conclusion Cell block and immunohistochemi-cal technique combination in the differential diagnosis of difficult pleural effusion has important clinical significance. It is worthy of popularization and further clinical application.
ABSTRACT
Objective: This paper is aimed at to evaluate B7-H1 expression as induced by human cytomegalovirus [HCMV] in extravillous cytotrophoblast cell line HPT-8 and possible underlying mechanism
Method: Real time PCR and flow cytometry were used to determine B7-H1 mRNA and protein before and after HCMV infection in HPT-8 cells. Western blot analysis was used to determine the level of MAPK phosphorylation in HPT-8 cell lines infected with HCMV
Results: 100TCID50 was found to be the most effective dose, capable of stimulating B7-H1 mRNA and protein expression in HPT-8 cells. When empty control group was considered to have a B7-H1 mRNA value of 1, B7-H1 mRNA was 4.32 in 100TCID50 group. In flow cytometry study, mean fluorescence intensity [MFI] of 100TCID50 group was 16.14, while empty control group was 1.34. Both mRNA and protein expression were found to be significantly increased [P < 0.05] in 100TCID50 group compared to empty control group
The result of Western blot analysis showed increase in B7-H1 expression caused by the extracellular signaling that was related to ERK activation and the ERK inhibitor U0126 was found to reverse this increase
Conclusion: HCMV upregulates B7-H1 expression in human extravillous cytotrophoblast cell line HPT-8, which is related to MAPK activation. Our result would be helpful in finding better therapies against intrauterine HCMV infection

ABSTRACT
Objecthe To equate the effects of recombinant human growth hormone (rhGH) on serum albumin lewis and intestinal mucosal morphology in rats with intracerebral hemorrhage. Methods A rat model of intracerebral hemorrhage was induced by autologous blood injection. Fifty-six SD rats were divided into sham-operation group (n =8), rhGH group (n =24; intraperitoneal injection of rhGH, 1 U/kg, once a day), and saline control group (n =24; intraperitoneal injection of equivalent normal saline, once a day). The rhGH and saline control groups were redivided into 1-, 7- and 14-day groups (n =8 in each group) after the procedure. The serum albumin concentration was detected at different time points in all groups. The changes of intestinal mucosal morphology were observed with Hematoxylin and Eosin (HE)staining and image analysis. Results Hie serum albumin lewis at all time points of intracerebral hemorrhage in the saline control group were all significantly lower than those in the sham-operation group (all P < 0. 01); The serum albumin level was increased gradually with the treatment process in the rhGH group, however, it was only significantly higher than the saline control group at day 14 (39.93 ±1.98 g/L νs. 37. 93 ±1.57 g/L) (P<0. 01). There were no significant differences between the rhGH group and the saline group in intestinal villus height and mucosal thickness at day 1 and 7 after intracerebral hemorrhage, however they were increased significantly at day 14 (P <0.01). The area of intestinal villi was reduced progressively at day 1, 7 and 14 after intracerebral hemorrhage, and with the treatment process the rhGH group was increased more progressively than the saline control group (P <0. 01). The depth of intestinal glands in the rhGH group was increased significantly than that in the saline control group (P <0. 01), but there was no significant difference at day 14; the density of glands in the rhGH group was significantly increased than that in the saline group at day 1 after intracerebral hemorrhage (P < 0. 01), and it was not increased significantly at day 7, however, it was not increased but decreased slightly at day 14. Conclusions The serum albumin level in rats with intracerebral hemorrhage was decreased significantly than that in the sham-operation group, and intracerebral hemorrhage could cause intestinal mucosal injury. rhGH increased the serum albumin level in rats with intracerebral hemorrhage. It might reduce intestinal mucosal injury to different degrees whether it was in the early or late intracerebral hemorrhage, and the late improvement was more significant. The improvement degree of rhGH on intestinal mucosal injury was positively correlated with the increased degrees of the serum albumin level.
