The nursing points mainly included psychological care of the patient before surgery,preoperative preparation,postoperative care and special nursing before and after deep brain stimulation opening. The patient's dance-like involuntary movements and compulsive behavior reduced significantly after the treatment with no complications.

Objective To investigate the blood-retinal barrier(BRB)function of porcine retinal pigment epithelial(RPE)cells cultured in vitro. Methods Primary porcine RPE cells were cultured,and the third generation were inoculated in a microporous filter with the filter membrane of polyvinylpyrrolidone(PVP)-free polycarbonate membrane.After 1,2,3 and 4 weeks of culture,the surface of filter membrane was observed by light microscope,and after 2 weeks of culture,the section of filter membrane was observed by light microscope and transmission electron microscope.Transepithelial electrical resistance(TER)was detected and the permeability was measured with fluorescein sodium(FS)and horseradish peroxidase(HRP). Results Primary porcine RPE cells were cultured successfully.RPE cells converged1week after inoculation; 2 and 3 weeks after inoculation,the density of RPE cells did not changed obviously; 4 weeks after inoculation,the density of RPE cells decreased.The characteristics of polarized growth of monolayer were found in RPE cells on the surface of filter membrane; 2 weeks after inoculation,the TER of RPE cells was(97.44?11.36)?/cm~2 which maintained till the 3rd week after inocubation.After incubated for 30 minutes,only 0.27% of FS and 0.17% HRP reached the inferior filter membrane,and the permeability rate of SF with low molecular weight was higher than which of HRP with high molecular weight. Conclusions The filter with PVP-free polycarbonate membrane may be used to set up the model of RPE cells with polarized growth of monolayer and investigate the barrier function of RPE cells.

This paper aimed to study clinical effectiveness of gabapentin in the treatment for pruritus and insomnia among patients with hemodialysis. Eighty patients with severe pruritus and insomnia during regular hemedialysis in Jiaozhou People's Hospital, Jiangsu were randomly divided into two groups with 40 patients each. Gahapentin 0. 1 g were given each patient every night for 4 weeks in one group and a modified-re]ease capsule of 8 mg chiorphenamine maleate was given each patient daffy for 4 weeks in the other group. Effectiveness of treatment was evaluated by improvement of itching symptoms and Pittsburgh Sleep Quality Index (PSQI) scores for insomnia in the patients. Itching improvement was observed in 85%(34/40) of the patients and PSQI scores obviously lowered in them four weeks after gabapentin treatment.However, itching improvement was observed only in 42% ( 17/40 ) of the patients and little change was observed in PSQI scores in them four weeks after chlorphenamine treatment It suggests that gabapentin can significantly improve quality of sleeping and itching symptoms in patients with hemodialysis and it is worthy popularizing in those with it.

Objective To prepare an active anti-tumor component, compound K (C-K), from saponins in leaves of Panax notoginseng (SLPN) using immobilized β-glucanase. Methods Two entrapments, alginate gel-1 (Alg 1) and alginate gel-2 (Alg 2), were evaluated for their ability to immobilize β-glucanase. The amount and purity of C-K obtained from the transformation process were analyzed by HPLC, and the immobilizing parameters were optimized. Results β-Glucanase can be immobilized and reused with either of the entrapment. However, using AIg 1 resulted in higher enzyme activity than Alg 2. The optimal concentration of the immobilized enzyme was 10%; The optimal crosslinking time was 4-6 h; and the optimal concentration of the crosslinking agent was 6%-7%. Conclusion Immobilized β-glucanase shows sustained enzyme activity, good ethanol tolerance, and was reusable for the preparation of C-K from SLPN.

Objective To document and analyze thepeak force and work during isokinetic pedaling at different linear speeds and the flexion-extension peak force ratio.Methods Thirty healthy adults were tested using the Legpress system of the IsoMED 2000 apparatus.Peak force,work and the flexion-extension peak force ratio were recorded and analyzed during isokinetic pedalingat 5 and 50 cm/s.Results The peak force applied and work done by the lower limbs were both significantly lowerwhen pedaling at 50 cm/s than at 5 cm/s.There was no significant difference in peak force or work between the left and right legs at 50 cm/s.The peak force ratio at 50 cm/s was significantly higher than at 5 cm/s.Conclusion The mechanical characteristics of the leg muscles during isokinetic pedaling vary greatly.It is advisable to choose different linear speeds or training modes accordingly.

Objective To explore the effect of dietary fat acids on incretin and islet function in healthy adults .Methods Before each test, healthy subjects received a 1-week pre-experiment eucaloric diet .Fifteen subjects consumed two meals containing different fat acids , including high saturated fat acid ( HSF) and high monounsaturated fat acid ( HMF) .On two separate occasions,they underwent a minimum of 1-week washout between meals .At 0,30,60,120,180 and 240 min following meal intake, the plasma concentrations of gastric inhibitory polypeptide (GIP), glucagon-like peptide-1(GLP-1) and serum concentrations of glucose, insulin, triglycerides ( TG) and free fatty acid ( FFA) were measured.Results Postprandial glucose did not increase significantly following HSF and HMF meals (P>0.05).Compared with HMF meal, significant increase in AUCins240min,AUCTG240min and AUCFFA240minwas observed following HSF meal (P<0.05).Compared with HMF meal,a significant decrease in AUCGIP30min, AUCGIP240min, AUCGLP-1 30min and AUCGLP-1 240min was found following HSF meal (P<0.05).No significant difference was observed inΔI30/ΔG30 following HSF and HMF meals (P>0.05). AUCI/AUCG was significantly lower following HMF meal as compared with HSF meal (P<0.05).Conclusion This study demonstrates that the function of GIP ,GLP-1 andβcell is affected by the dietary fat acids in healthy adults .The HMF meal may stimulate GIP and GLP-1 secretion to a greater extent than HSF meal .

Objective To verify the presence of anti-ovary antibodies in systemic lupus erythematosus (SLE) and its possible correlations with serum levels of hormone profile and menstrual disturbances in patients with SLE.Methods Clinical data of 78 consecutive paticnts who fulfilled 4 or more of the ACR 1997 revised criteria for SLE were studied and compared with 40 age-matched healthy controls,including anti-ovary antibodies.Results 27 (34.6％ ) patients with SLE,and 1 (2.5％) of the healthy controls tested positive of anti-ovary antibodies.The levels of E2 and T and P decreased[ E2:( 80.96 ± 36.2 ) ng/L vs ( 118.53 ± 42.4 ) ng/L; T:( 3.85 ± 1.18 ) nmol/L vs ( 6.43 ± 2.28 ) nmol/L; P:( 1.37 ± 0.59 ) μg/L vs ( 3.92 ± 1.23 ) μg/L],and the levels of FSH and LH and PRL increased in SLE patients when compared with healthy controls [ FSH:( 19.17 ± 9.26)IU/L vs (10.18 ±7.27 )IU/L; LH:( 21.19 ± 12.44)IU/L vs (13.79 ±8.27)IU/L;PRL:(6.18 ± 2.27 ) μg/L vs (2.37 ±0.63)μg/L,P ＜0.05 orP ＜0.01].The higher SLEDAI score,higher rate of menstrual disturbances (6.3 ±2.8 vs 3.5 ± 1.7,81％ vs 47％,P ＜0.05 or P ＜ 0.01 ) and decreased serum level of E2 [ (64.13 ± 26.36 ) ng/L vs ( 82.83 ± 28.71 ) ng/L,P ＜ 0.05 ]were found in SLE patients with anti-ovary antibodies positive than in SLE patients with anti-ovary antibodies negative.Conclusions The presence of anti-ovary antibodies was 34.6％ in SLE,and may correlate to decreased serum level of E2 and menstrual disturbance.

Objective To study the characteristics of cognitive development of newborns with auditory event related potentials (aERP).Methods Thirty full-term neonates who were admitted to Changzhou Children's Hospital and met the inclusion criteria, those with neonatal neural behavioral score over 37 and both ears passed the hearing screening, and exclusion criteria, those who suffered from perinatal brain injury, were sclccted randomly.Thcy wcre divided into three groups according to the days of age (group 1 : 1-10 days;group 2:11-20 days;group 3:21-28 days).aERP was recorded with auditory Oddball paradigm.The data were collected and analyzed by Brain Electrical Source Analysis software.Relationship between N2latencies/areas among the three groups and their age was researched with Pearson correlation analysis.Results During the neonatal period, there was a significant negative correlation between N2 latency and neonatal age in days (r=-0.609, P ＜ 0.05), while significant positive correlation was shown between N2 area and the age (r=0.689, P ＜ 0.05).In Fz and Cz leads, the total average waveform diagram of the three groups showed spacious flat, less smoothed curve, and mostly jagged pattern.N2 area in group 1 showed a complex plurality of peaks, and regular, soaring waves, which changed into single wave thereafter, in group 2 and 3.The N2 latencies tended to shorten gradually.Conclusions Neonatal cognitive competence, including concentration and discrimination ability, would be improved with their growth.
