Objective: To evaluate feasibility of using European Nutritional Risk Screening 2002(NRS2002) for nutritional status assessment in primary hospital.Methods: 799 patients were enrolled in this study.697 patients who were according NRS request were assessed using NRS method in hospitalization day.The patient whose NRS scores were higher than 3 were justified under nutritional risk.102 patients who were not according NRS request were assessed by exeamining the serum albumin(ALB) in the next day.The patients whose serum ALB was lower than 35 g/L were justified malnutrition.Results: There were 697 patients could be evaluated by NRS method.Body Mass Index(BMI) was lower than 18.5 in 159(22.8%) cases and NRS scores were ≥3 in 240 cases(34.4 %) among 697 cases.Serum albumin was lower than 35 g/L in 31 (30.4%) cases among 102 cases who could not be evaluated by NRS method because of incapable of standing up(66/102,64.7%) and ascites or hydrothorax(17/102,16.7%) and concomitance of above-mentioned causes(11/102,10.8%) and coma(8/102,7.8%).Conclusion: Assessment of nutritional status of hospitalized patients in primary hospital using NRS2002 method is feasible.The patients who could not be evaluated by NRS 2002 method can be assessed by assaying serum ALB.

Objective To determine the biomechanical parameters of left ventricular by using velocity vector imaging (VVI),and to indirectly assess the coronary artery stenosis with VVI in the patients with coronary artery disease (CAD).Methods 52 patients who had one coronary artery lesions at least diagnosed by coronary angiography (CAG)were divided into coronary artery mild stenosis group and severe stenosis group;2 1 patients in mild stenosis group had one coronary stenosis <75%;31 patients in severe stenosis group had one coronary artery stenosis ≥75% at least.At the same time,20 cases of normal people without coronary artery stenosis showed by CAG were selected as normal control group. VVI was used to detect the left ventricular wall segments of the overall longitudinal strain (GLS ), the overall circumferential strain (GCS ) and the overall radial strain (GRS ). Results The absolute values of GLS,GRS,GCS of the patients in mild and severe coronary artery stenosis groups were significantly decreased than those in normal control group(P<0.05),and the strain parameters in severe stenosis group were decreased more significantly, there were significant differences compared mild stenosis group (P<0.05 ). The distribution of the segments with decreased longitudinal strain matched the LV myocardial segment with the coronary stenosis rate ≥ 75%,and GLS had the most sensitivity.The GLS in normal control group,mild stenosis group and severe stenosis group were negatively correlated to left ventricular ejection fraction (LVEF)(r=-0.58,P<0.05;r=-0.51,P<0.05;r=-0.43,P<0.05).GLS-16.14 % was used to assess the severe coronary artery stenosis with requiring the implementation of PTCA treatment as the diagnostic cut-off point with sensitivity 96.8%, specificity of 70%, the highest Yuedden index 0.668. Conclusion The decreasing of left ventricular strain could be detected by VVI, which suggests that severe coronary artery stenosis exists in coronary artery;the distribution of the segments with significantly decreased strains can be used to assess the coronary lesions and stenosis degrees.

Objective To compare the efficacy of laparoscopic gallbladder bed dissection(LGBD)between retrograde plus anterograde and anterograde only manners.Methods All of 575 cases of laparoscopic cholecystectomy(LC)were randomly divided into two groups(group A and group B).Patients underwent LGBD with retrograde plus anterograde mannerin group A(297 cases)oronly with anterograde manner in group B(278 cases)respectively.The efficacy and safety were compared between two groups.Results The operative time were(10.0±3.7)min and(13.0±3.9)min in group A and group B respectively (P<0.05).There were 33 cases of bleeding volume more than 5 ml in group A with 85 cages in group B (P<0.05).Three cases of gallbladder rupture were found in group A compared with 10 cases in group B (P<0.05).Postoperative fluid collection in gallbladder bed occurred in 5 cases in group A compared with 19 cases in group B(P<0.05).The conversion rate was 3.70%(11/297)and 3.96%(11/278)in group A and group B respectively(P>0.05).One cage of abdominal fluid collection was observed in group A whichwas relieved after conservative therapy.No other complications occurred.Conclusions LGBD applying retrograde plus anterograde manner may shorten the operative time,decrease the bleeding during operation and minimize the postoperative complications.Surgeons might benefit from its advantage of easier manipulation.

Objective:To analyze the characteristics and prognosis of visual field of Leber hereditary optic neuropathy (LHON) with G11778A mutation.Methods:A retrospective clinical study. Twenty-two (44 eyes) of LHON patients diagnosed with G11778A site mutation by mt-DNA examination from May 2008 to February 2018 in Ophthalmology Department of Dongfang Hospital of Beijing University of Chinese Medicine, were enrolled in this study. All patients underwent best corrected visual acuity (BCVA), visual field and optical coherence tomography (OCT). The BCVA examination was performed using the international standard visual acuity chart, which was converted into logarithm of the minimum angle of resolution (logMAR) BCVA for record. The thickness of the retinal nerve fiber layer (RNFL) in the 200μm×200μm annular region 1.73 mm outside the optic disc was measured by OCT. At least 7 visual field examinations were performed within one month before and after 2, 4, 8, 12, 18, 24 and 30 months of the course of disease by using Octopus 101 perimetry. Among 44 eyes, 27 eyes were detected with G2 procedure (G2 group) and 17 eyes were detected with LVC procedure (LVC group). The mean field defect (MD) and mean optical sensitivity (MS) were used as the main outcome indexes. According to the onset age, the patients were further divided into the ≤14 years old group and>14 years old group. There was a significant difference in initial logMAR BCVA between the G2 group and LVC group ( t=4.994, P=0.000), but there was no significant difference in gender ( χ2=1.896, P=0.169) and age ( t=0.337, P=0.708) between the two groups. Independent sample t test was used for comparison between groups, paired t test was used for comparison within groups, and one-way analysis of variance was used for comparison between groups. The statistical data were compared by χ2 test. Results:In the G2 group, the MD value of the subgroup of children (≤14 years old) decreased gradually during the follow-up period, and the MD value since 18 months after onset was significantly lower than the value of 2 months after onset ( t=3.813, 4.590, 5.033; P=0.002, 0.001, 0.000). No obvious visual field index changes were seen in other subgroups ( P>0.05). The central scotoma was the most common type of visual field defect in the early stage, and the diffuse defect was the most common type of visual field defect in the late stage. There was a significant difference in the types of visual field distribution between the early and late stage in G2 group ( χ2=17.414, P=0.015). There was no significant difference in the type of visual field distribution between the early and late stage in LVC group ( χ2=4.541, P=0.474). The MD value in the G2 group remained stable within 8 months after onset, but significantly improved after 18 months after onset ( t=2.100, 3.217, 3.566; P=0.046, 0.003, 0.001). The MS in the LVC group did not significantly improve during follow-up ( P>0.05). The average visual acuity of the G2 group was significantly improved from 12 months ( t=3.039, 3.678, 4.264, 5.078; P=0.008, 0.002, 0.001, 0.000). The visual acuity of the eyes in the G2 group was better than that of the LVC group during all follow-up periods ( P≤0.05). The RNFL thickness of all patients continued to decrease after onset, but the RNFL thickness was significantly higher at 4, 8, 18, 24, 30 months in the G2 group than those in the LVC group ( t=2.471, 2.269, 2.474, 2.509, 2.782; P=0.018, 0.028, 0.017, 0.016, 0.008). Conclusions:The main types of visual field defect of LHON with G11778A mutation are the central scotoma in the early stage, while the diffuse defect and central scotoma are both very common in the later stage. The visual field of LHON patients examined by G2 procedure is significantly improved during the follow-up, as well as the visual acuity improved significantly, and the visual field improvement in younger cases (≤14 years old) is better than that of older cases (>14 years old), but the visual field of the LVC procedure cases did not improve during follow-up.

Objective To investigate the clinicopathological features and prognostic factors in patients with low grade glioma. Methods Eighty- seven patients with low grade glioma confirmed by cytological examination were retrospectively analyzed. Results Among 87 patients, male accounted for 62.1%(54/87), and the average age was 36.2 years. The average followed- up time was 51.4 months (3-135 months), and 5 cases were lost in follow-up. The follow- up rate was 94.3% (82/87). The 3- year survival rate was 84.1%, and the 5- year survival rate was 66.7%. The 3- year survival rate was related to clinical symptoms, maximum diameter of tumor and the extent of resection (P<0.01 or<0.05);and the 5- year survival rate was related to years, Karnofsky score, clinical symptoms, maximum diameter of tumor, the pathology classification and extent of resection (P<0.05 or<0.01). Conclusions Low grade glioma is more common in male patients and patients under the age of 40 years. Age below 40 years, Karnofsky score ≥ 70 scores, only epilepsy symptom, tumor diameter below 6.0 cm, oligodendrogliomas, complete resection or subtotal resection are positive prognostic factors. Postoperative radiotherapy can reduce the rate of tumor progression.

Objective To evaluate the clinical application of enteral nutrition by nasojejunal tube insertion and by percutaneous endoscopic gastrostomy (PEG) in elderly patients.Methods A total of 65 elderly patients with dysphagia recruited at our department from January 2010 to November 2014 were divided into the nasojejunal tube feeding group (35 cases) and the PEG feeding group (30 cases).Differences between these two groups in nutritional indexes,immunological indexes,complications and mortality were analyzed retrospectively.Results Serum total protein,albumin and prealbumin and upper arm circumferences all increased after treatment with nasojejunal tube feeding or percutaneous endoscopic gastrostomy (P＞0.05).There was overall improvement in nutritional status,as assessed by Nutritional Risk Screening 2002 (NRS2002).Specifically,the before/one month-after-treatment ratio of scores was 3.72±0.91/1.90±0.61 (t=7.24,P＜0.01) for the nasojejunal tube feeding group and 3.52±1.23/2.02±0.53 (t=4.17,P＜0.01) for the PEG feeding group.Compared with NRS2002 scores at one month post-operation,further improvement was achieved at 3 months postoperation both for the nasojejunal tube feeding group (1.89±0.65,t=5.21,P＜0.01) and for the PEG feeding group (1.91±0.62,t=4.40,P＜0.01).There was no difference in the indexes of nutrition,immune status or mortality between the two groups (P＞0.05).Although improvement in CD3+,CD4+,CD8+,CD4+/CD8+,IgA,IgG,and IgM was seen in both groups after operation,the differences did not reach statistical significance (P＞0.05).The incidence of aspiration pneumonia was notably lower (P＜0.05) while the incidence of diarrhea was much higher (P＜0.05) in the nasojejunal tube feeding group than in the PEG feeding group at one month and three months.The two groups had similar causes of death and mortality rates.Conclusion Both nasojejunal tube and PEG feeding can improve the nutritional status of elderly patients with dysphagia.However,the choice for the route of nutrition should be individualized.

Objective Toinvestigatetheimpactofthedifferentrupturepoints(sac,neck,andtop) of intraoperative aneurysm rupture (IAR)on the prognosis of patients in anterior circulation aneurysm clipping.Methods Theclinicaldataof135consecutivepatients(148aneurysms)acceptedmicrosurgical aneurysm clipping from May 2009 to March 2012 were analyzed retrospectively. The prognostic evaluation of the patients after procedure was assessed by using the Glasgow outcome scale (GOS). The different aneurysm rupture points of IAR were used as influencing factors,and the relationship between the different rupture pointsandtheprognosisofpatientswasanalyzed.Results Duringclippingof148aneurysmsin 135 patients,31 aneurysms in 30 patients had intraoperative rupture (20. 9% of the aneurysms, 22.2% of the patients). Nine rupture points occurred on the top of aneurysms,17 occurred on the sac,and 5 occurred on neck. The Glasgow outcome scale (GOS)scores 5,4,3,2 and 1 were in 17,8,2,1 and 2 patients,respectively. A total of 25 patients had good prognosis and 5 cases had poor prognosis. There were no significant differences in the impact of different rupture points of IAR on the prognosis in patients of IAR (OR,100. 00,95% confidence interval 6. 764-18. 344,P=0. 006). Of the 25 patients with aneurysm sac or top rupture,1 case had poor prognosis. Of the 5 patients with aneurysm neck rupture, 4caseshadpoorprognosis.Conclusion Inanteriorcirculationaneurysmclipping,thedifferent aneurysm rupture points may have significant impact on the prognosis of patients,the aneurysm neck rupture is a main factor for resulting in the poor prognosis of patients.

Objective:To evaluate the effect of left ventricular hypertrophy and deformation on cardiac function in patients with uremic cardiomyopathy (UCM) by using the technology of two dimensional speckle tracking imaging (2D-STI).Methods:A total of 67 UCM patients were randomly divided into the normal cardiac function group (subgroup A,32 cases) and the abnormal cardiac function group (subgroup B,35 cases)according to the New York Heart Association points (NYHA-P).A total of 30 healthy subjetcs served as the control group.Parameters including left ventricular ejection fraction (LVEF),left ventricular mass index (LVMI),left ventricular spherical index (LVSI),left ventricular myocardial mean radial strain (MRS),mean radial strain rate (MRSR),mean longitudinal strain (MLS),local systolic twist angle (STA),and mitral annulus maximum displacement (TMAD) were detected.Results:MLS,MRS,MRSR,LVSI,STA and TMAD in the Group A and Group B were lower than that in the control group (P＜0.05),and LVMI in the Group A and Group B was increased than those in the control group (P＜0.05);LVEE MLS,MRS,MRSR,LVSI and STAin the Group B was decreased than that in the Group A (P＜0.05).MLS in the Group A and B were positively correlated with LVEF and LVSI,but negatively correlated with LVMI.Using the point of 14.10％ for MLS to evaluate UCM patients with NYHA-P＞4 points,the sensitivity,the specificity and Yuedden index were 90.5％,71％ and 0.585,respectively.STA in UCM patients were lower than that in the control (P＜0.05).Conclusion:2D-STI possesses a unique advantage in detecting left ventricular strain and strain rate on left ventricular regional function in UCM with left ventricular hypertrophy and ventricular deformation.There is no direct correlation between the left ventricular hypertrophy and ventricular deformation,but the ventricular hypertrophy and deformation are correlated with regional cardiac function and clinical cardiac function.Left ventricular regional dysfunction may occur before cardiac hypertrophy and deformation.

Objective To compare the effects of cleaning oral among different nursing methods for patients with dysphagia after brain injury who take food by gastric tube as well as by mouth. Methods A total of 59 patients with dysphagia after brain injury were divided into research group ( 29 cases, mouth nursing by modified method of brushing their teeth and irrigation ) and control group ( 30 cases, mouth nursing by traditional oral care routine) according to the random number table method from October 2012 to May 2014. Results were observed by comparing oral condition, indexes of pharyngeal swab culture and water-swallowing test. Results Incidence rates of halitosis and unclean mouth were all 13. 8% in the research group which were lower than those (73. 3%, 63. 3%) in the control group with statistically significant differences (χ2 =21. 208, 15. 214;P<0. 01). The effective rate of water-swallowing test was 79. 3% in the research group which was higher than that (56. 7%) in the control group (χ2 =12. 202,P<0. 01). There was no statistically significant difference in abnormity rates between two groups before intervention (P >0. 05). The abnormity rate in the research group was lower than that in the control group at 4th week (χ2 =8. 958,P <0. 01). There was statistically significant difference in abnormity rate before interventions and at 4th week in the research group (P<0.01), with no statistically significant difference in the control group (P>0.05). The rate of oral mucosa bleeding was 3. 4% in the research group and 6. 7% in the control with no statistically significant difference (χ2 =0. 316,P >0. 05), but there was no mechanical injury of oral mucosa in two groups. There was no statistically significant difference in index of water-swallowing test between two groups before interventions ( P>0. 05), with significant difference at 4th week (P<0. 01). Conclusions The implementation of mouth nursing by modified method of brushing their teeth and irrigation not only can achieve the purpose to clean oral effectively, but also can reduce oral bacteria and promote the recovery of swallowing function.
