Objective To evaluate the nutrition intervention on advanced colorectal cancer chemotherapy patients quality of life. Methods 70 colorectal cancer patients (NRS 2002 score was more than or equal to 3 points) with chemotherapy from January 1st, 2013 to June 31th, 2014 were collected. The patients were randomly divided into intervention group (35 patients) and the control group (35 patients). The intervention group received personalized recipe which was developed by a team containing nurse specialist, chief psychiatrist, family members and patients themselves. The control group was treated with a normal diet guidance. The two groups of patients when they were treated after the second days of the first admission (before intervention), the end of the 6th courses of chemotherapy and the 12th courses of chemotherapy were evaluated by the European Organization For Research and Treatment Quality of Life Questionnaire-C30 (EORTC QLQ-C30). Nutritional indicators and the total life condition of the two groups at different time were compared. Results There were 5 cases off in the intervention group and the control group respectively. After the 12th courses of chemotherapy, the intervention group serum albumin (ALB) and the mean serum prealbumin (PAB) were improved 4.10 and 74.14; and the control group were-0.09 and-0.08, there were significant differences between the two groups (t=3.202, 3.623, P<0.05).The total quality of life of the intervention group was 25.87 points while the control group was 35.13 points, there was significant difference between the two groups (t=3.321, P<0.05). The intervention group got the total health status was (72.28 ± 20.97) points after the intervention, and before the intervention was (56.67 ± 14.08) points. Meanwhile the total health status was statistically significant (t=7.01, P<0.05). Conclusions There is a significant nutritional improvement in colorectal cancer patients with chemotherapy after nutritional therapy leading by nurse specialist, which is worthy of application.

Objective To study the effect of different family nursing methods on major catheter-re-lated complications in cancer patients with peripherally inserted central catheter (PICC) during chemother-apy intermission so as to reduce the incidence of complications and prolong the indwelling time and service life of the catheter. Methods We randomly divided 213 cancer patients who were discharged from hos-pital with PICC into two groups. One group(108 cases) routinely came back to our outpatient clinic and the other (105 cases) went to the community for nursing of the catheter. Results The total incidence rate of complications of the group who came back to our outpatient clinic for nursing of the catheter was 13.8%(15/ 108) and the other group was 51.4%(54/105). There existed statistical significance between the two groups (P<0.01). Conclusions There exists correlation between different family nursing methods and catheter complication rate. We suggest patients come back to our outpatient clinic for nursing of the catheter as pos-sible as they can.

The purpose of this study was to investigate the natural infection of Angiostrongylus cantonensis (A. cantonensis) in rodents in Fujian Province and provide more scientific evidences for control and prevention.?Rats captured with cages were numbered, and the species, gender and maturity were identified in each village every day. Rats' hearts and lungs were taken out and soaked into physiological saline solution to tear to pieces. The detected A. cantonensis were put into physiological saline solution in other glassware then the number and gender were identified. This investigation was conducted in 67 villages in 35 towns, covering 23 counties in 9 cities and regions. Except Shanghang County in Longyan city and Pingtan County in Fuzhou city, rodents infected with A. cantonensis was found in 21 counties. Of 4 890 rats were examined and 434 infected rats were identified with an infection rate of 8.90%. Rattus norvegicus had the highest infection rate of 17.75% (315/1 775), following by Rattus flavipectus with an infection rate of 6.21% (49/789). Additionally, the infection rates of the Musk shrew and Mus musculus were 2.81% (29/1 032) and 2.52%(3/119), respectively (χ2＝185.06, P＜0.001). Moreover, the infection rate of adult rats (21.37%) was much higher than that of immature rats (11.11%) (χ2＝14.50, P＜0.05). These results indicated that the A. cantonensis infection of rodents has covered most area in Fujian Province and the geographical distribution of infected rats was similar with that of Ampullaria gigas.

Objective To study the effect of astragaloside on TGF-β1,SMAD2/3,and α-SMA expression in the kidney tissue of diabetic KKAy mice,and evaluate its potential role in renal interstitial fibrosis.Methods 20 type 2 diabetic KKAy mice were randomly divided into model group and astragaloside group,while 10 male C57BL/6J mice were selected as the control.Astragaloside at 40 mg · kg-1 · d-1 was given when the KKAy mice fed with high-fat diet to 14 weeks old.The mice in the control and model group received normal saline at 40 mg · kg-1 · d-1.Blood glucose meter was used to detect the blood glucose value of each mice at 16th,20th and 24th week.The mice were killed at 24 weeks old and the kidney tissue samples were collected.Pathology morphological changes were observed.Results (1) blood glucose value:cmpared with the control group,the blood glucose value of KKAy mice at 14 week increased significantly,and that of model group also increased significantly at 16th,20th and 24th week (P＜0.05);the blood glucose value of astragaloside group decreased compared with control group (P＜0.05).(2) Morphology of kidney:in the control group,the glomerular and tubular had clear structure,there was no renal interstitial fibrosis;in the model group,the renal glomerular mesangial matrix had broaden,mesangial cell had increased,renal tubular epithelial cell cytoplasm showed vacuole degeneration,renal interstitial inflammatory cell had increaised.In astragaloside group,there were few renal tubular epithelial cell cytoplasm,and there was no obvious fibrosis.(3)TGF-β1,SMAD2/3,and α-SMA expression levels of the kidney issuse:compared with control group,mice in model group up-regulated TGF-β1,SMAD2/3 and α-SMA expression (P＜ 0.05).TGF-β1,SMAD2/3,and α-SMA expression levels in astragaloside group were significantly lower than those in the model group (P＜0.05).There was few phosphorylated SMAD2/3 expression in renal tubular and glomerular nuclei,while that of model group increased (P＜0.01),and compared with model group,that of the astragaloside group decreased (P＜0.05).Conclusion Astragaloside can delay the renal fibrosis process in diabetic mice by influencing the TGF-β/SMADS signaling pathway and down-regulating TGF-β1 and α-SMA expression,thus to relieve renal fibrosis in diabetic mice.

Objective To investigate the clinical significance of serum lactate dehydrogenase (LDH) and its isoenzymes,M or H subunits in the retreated patients with multiple myeloma(MM).Methods 141 medical records of retreated patients with multiple myeloma were collected,and the relationship of LDH and its isoenzymes,subunits with DS staging system,ISS staging system,creatinine,bone marrow plasma cell percentage,immunoglobulin and microglobin was analyzed.Results Serum total LDH activity was not significantly related to DS staging system and ISS staging system.LDH1 percentages was negatively correlated with ISS staging system (P＜0.01),and LDH4 percentages positively associated with ISS staging system (P＜0.05).LDH activity,absolute value of LDH1 ,LDH2,LDH3,LDH4,and H subunits were positively linked to serum creatinine in myeloma kidney disease patients with renal inadequacy (P＜0.05).Both percentage and absolute value of LDH5 were negatively correlated with bone marrow plasma cell percentage (P＜0.01 and P＜0.05 respectively).Conclusion The detection of serum LDH isoenzyme is more valuable than total LDH activity in retreated patients with multiple myeloma.

Objective To make etiological and epidemiological investigation on the infection of Angiostrongylus canto-nensis in 8 pupils in Changle City. Methods (1) CSF of patients was examined with the conventional method to detect pathogens and eosinophiles. (2) The fecal samples of wild rodents were collected from the spot and examined microscopically to discover the first stage larvae of A. cantonensis. (3) Snails (Pila gigas) were collected in the spot. The smashed head tissue was examined for the third stage larvae of A. cantonensis. (4) The patient's clinical symptoms and physical signs were recorded with an emphasis on central nervous system. Results (1) Two larvae of the third stage of A. cantonensis were found in CSF of one patient. Eosinophiles occupied 68% of the cell number in average (ranged from 47% to 83%) in CSF of the 8 patients. (2) The infection rate of the first stage larvae of A. cantonensis was 39.3% (44/112) in feces of the rodents. (3) The infection rate of the third stage larvae of A. cantonensis was 40. 0% (82/205) in the snails. (4) Major clinical manifestations in the 8 patients included: severe headache(8/8), dizziness(8/8), nausea(8/8), vomiting(8/8), lethargy(7/8), lower limb hypody-namia(7/8). Conclusion The confirmation of severe infection of A. cantonensis in 8 child patients demonstrated that a natural nidus of angiostrongyliasis is present in Chengle City.
