Objective To explore the reasonable nursing interventions of advanced schistosomiasis patients. Methods The medical records of 52 advanced schistosomiasis patients hospitalized from 2008 to 2013 were collected,and the nursing interven-tions were summarized. Results The 52 cases of advanced schistosomiasis included 38 men and 14 women,with a mean age of 65.8 years(57-75 years). Totally 53.8%of the subjects were schistosome positive by IHA test,67.3%positive by ELISA,and 21.2%positive of HBsAg. There were 13 cases of ascites type,34 cases of megalosplenia type,and 5 cases of dwarfism type of ad-vanced schistosomiasis. Following the therapy together with nursing interventions,73.1%achieved clinical cure,23.1%achieved stable,and 3.8%achieved improvement. The major nursing interventions involved basic nursing,diet nursing,treatment nursing, physiological nursing and surgical nursing. Conclusion The scientific and reasonable nursing interventions can improve the ther-apeutic efficacy and prognosis in advanced schistosomiasis patients,as well as improve their quality of life.

Objective To evaluate the clinical efficacy ofZi Wu Liu Zhu Na Jia needling (acupuncture based on midnight-noon ebb-flow theory) in treating spastic hemiplegia after cerebral stroke by using surface electromyography (sEMG).Method Fifty-two patients with spastic hemiplegia due to cerebral stroke were randomized into a treatment group and a control group, 26 cases each. The two groups were both intervened by conventional rehabilitation training. In addition, the treatment group was givenZi Wu Liu Zhu Na Jia needling and the control group was given ordinary acupuncture. The two groups were treated once a day, 15 sessions as a course. The ambulation ability, muscle tension, neurological deficit score (NDS), Fugl-Meyer Assessment Scale (FMA), and Berg Balance Scale (BBS) were evaluated before the intervention and after 2 treatment courses, and the sEMG signals were also collected and analyzed.Result The Holden's Functional Ambulation Classification (FAC) and Modified Ashworth Scale scores were significantly changed in the two groups after the intervention (P<0.01). After the intervention, the FAC and MAS scores in the treatment group were significantly different from those in the control group (P<0.05). The NDS, FMA and BBS scores were significantly changed in the two groups after the treatment (P<0.05). The NDS, FMA and BBS scores in the treatment group were significantly different from those in the control group after the treatment (P<0.05). Of the sEMG signals, H/M max in the treatment group was significantly different from that in the control group after the intervention (P<0.01).Zi Wu Liu Zhu Na Jia needling with rehabilitation training can significantly mitigate the muscle tension and promote the activities of daily living in patients with spastic hemiplegia after cerebral stroke.

BACKGROUND:Recent studies have demonstrated that surgical trauma leads to lipid peroxidation in erythrocytes.However,injured erythrocytes play an important role in thrombosis following replacement.OBJECTIVE:To evaluate the influence of artificial total knee replacement on the lipid peroxdation in erythrocytes,and the prophylactic treatment of vitamin E and fructose 1,6 diphosphate(FDP)on it.DESIGN,TIME AND SETTING:Contrast clinical study,which was carried out in the Department of Otthopaedics,Affiliated Hospital of Nantong University from January 2003 to June 2006.PARTICIPANTS:Sixty patients with knee osteoarthritis who underwent artificial total knee replacement by anesthesia of epidural block were divided into four groups,including control group,vitamin E group,FDP group and vitamin E+FDP group,with 15 cases in each group.METHODS:Vitamin E was orally taken in the vitamin E group three days before replacement,three times a day,100 mg for each.The administration was performed until the surgical morning.Thirty minutes after the operation,FDP(10 g)was intravenously dripped in the FDP group.Additionally.vitamin E was also orally taken in the vitamin E+FDP group three days before replacement,three times a day,100 mg for each;on the surgical morning,FDP(10 g)was intravenously dripped on the first 30minutes.Blood samples were taken for biochemical determination before and after the operation at 1,3,5,and 7 days.MAIN OUTCOME M[EASURES:Corltents of malonaldehyde(MDA)and cuprum/zincum/superoxide dismutase (Cu-Zn-SOD)in the erythrocytes.RESULTS:MDA level in the vitamin E group and FDP group was significantly higher than that in the vitamin E+FDP group before and 5 and 7 days after replacement(P<0.05);while,Cu-Zn-SOD level was significantly lower(P<0.05).Otherwise,there were no significant differences in vitamin E+FDP group before and after replacement(P>0.05).CONCLUSION:The artificial total knee replacement can enhance lipid peroxidation and decrease antioxygen capability.However,the combination of vitamin E and FDP can prevent and relieve lipid peroxidation and antioxygen capability after replacement.

Objective:To examine the adiponectin level in gingival crevicular fluid(GCF)in patients of chronic periodontitis with dia-betes mellitus type 2.Methods:20 patients of diabetes mellitus type 2 with chronic periodontitis(DM&CP),20 of periodontitis(CP) and 20 health subjects(H)were included.The periodontal indexes (SBI,PLI,PD and AL)were measured,GCF samples were quan-tified by periotron 8000,the adiponectin content in GCF was tested by adiponectin ELISA kit.The relationship between the adiponectin level in GCF and the periodontal indexes of the DM&CP patients was analyzed statistically.Results:The adiponectin level in GCF in group DM&CP was significantly lower than that in the other 2 groups(P <0.05).The adiponectin levels in GCF in group CP and H were not statistically different.The adiponectin level in GCF was negatively correlated with PD and AL(P <0.05),but had no correlation with SBI and PLI(P >0.05).Conclusion:Decrease of adiponectin in GCF may play a role in the development of DM&CP.
