Objective:To explore efficacy of the rehabilitative strategy in hospitalized schizophrenics.Method:Sixty-four schizophrenic patients were randomly divided into the intervention group and the control group.Both groups received the anti-psychotics therapy, but the teamwork education,medication management skills training module, symptom management skills training module were only given to the intervention group for ten weeks. And a one-year follow-up was carried out after their discharge from hospital. All subjects were evaluated with the Positive and Negative Syndrome Scale (PANSS), Nurses` Observation Scale for Inpatient Evaluation-30 (NOSIE-30), Insight and the Attitude to Treatment Scale, Social Disability Screening Schedule (SDSS), Morning Side Scale. We also recorded the relapse rate, reemployment rate, and re-hospitalization rate. Result:The clinical outcome of the intervention group was significantly superior to the control group on overall improvement according to PANSS (31.17?3.13 vs 52.34?13.02,7.34?1.08 vs 12.36?4.28,7.76?2.13 vs 13.26?4.50,16.13?1.82 vs 32.17?9.82 ),increase of active factor score of NOSIE-30 (-18.3?3.2 vs 14.4?6.7),and the reduction of inactive factor score of NOSIE-30(9.4?6.2 vs -22.3?7.4).The relapse rate(9.4% vs 54.8%),re-hospitalization rate(3.2% vs 42%),reemployment rate(37.5% vs 9.6%)were also better in the intervention group.Conclusion:The effect of rehabilitative strategy for schizophrenic patients not only improves the symptom, but also their social function.

Surface electromyogram (sEMG) may have low signal to noise ratios. An adaptive wavelet thresholding technique was developed in this study to remove noise contamination from sEMG signals. Compared with convention- al wavelet thresholding methods, the adaptive approach can adjust thresholds based on different signal to noise ratios of the processed signal, thus effectively removing noise contamination and reducing distortion of the EMG signal. The advantage of the developed adaptive thresholding method was demonstrated using simulated and experimental sEMG recordings.

OBJECTIVETo investigate the clinical outcomes of cannulated screw combined with buttress plate in treating transarticular shear fractures of the distal humerus.

METHODSFrom July 2008 to December 2011, 17 patients with shear fractures of the distal humerus were treated with cannulated screw combined with buttress plate. Among them, included 10 males and 7 females aged from 20 to 59 years old (mean 36.5). All the fractures were classified into type I (8 cases), type II (1 case), type III (3 cases) and type IV (5 cases) according to Bryan-Morrey and McKee classification. According to AO/ASIF classification, 10 cases were type 13B3.1, 7 cases were type 13B3.3; according to Dubberley classification, 5 cases with type 1A, 2 cases with type 1B, 2 cases with type 2A, 2 cases with type 2B, 4 cases with type 3A, 2 cases with type 3B. There were 12 cases with fresh injuries, 4 cases with old injuries. All fractures were closed injuries. Complications and range of motion of elbow were observed, and clinical efficacy were evaluated by Broberg-Morrey standard.

RESULTSAll patients were followed up with a mean time of 21.3 months (ranged, 18 to 24). All fractures obtained bone healing from 10 to 15 weeks with a mean of 12.5 weeks. No malunion or delayed healing occurred. Two cases occurred ossification in lateral collateral ligament attachment. 2 cases occurred heterotopic ossification in the capitellum in front of capsule joint. The range of elbow extension was (16 +/- 7) degrees, flexion was (115 +/- 9) degrees, the average are of pronation and supination was (65 +/- 5) degrees and (60 +/- 5) degrees respectively. According to Broberg-Morrey standard, there were excellent in 7 cases, good in 8 cases, fair in 2 cases, and average score was 92.44 +/- 4.64.

Objective To investigate the in vitro inhibitory effects of regulatory T cells ( Treg ) from unpregnant mice and pregnancy-induced regulatory T cells ( piTreg) on the proliferation of na?ve T cells and their differences .Methods The numbers of piTreg cells from allogeneic pregnant mice ( C57/B6 fe-male×BALB/c male) on day 12.5 (E12.5d) of gestation and Treg cells from unpregnant C57/B6 mice were detected respectively by flow cytometry .The percentages of piTreg cells and Treg cells in CD 4+T cells of age-matched female mice and their intracellular expression of Foxp 3 were analyzed .The in vitro inhibitory effects of piTreg cells and Treg cells on the CFSE-labeled na?ve T cells ( effector cells ) were compared in a one-way mixed lymphocyte culture system using mitomycin C-inactivated CD4-T cells as stimulator cells . Results The level of piTreg cells in splenic mononuclear cells was significantly higher than that of Treg cells (P<0.001) from normal mice.Foxp3 was highly expressed in both piTreg cells and Treg cells , howev-er slightly increased in piTreg cells .Moreover , piTreg cells had a significant stronger in vitro inhibitory effect on na?ve T cells proliferation than that of Tregs cells (P<0.006), which was in a cell-dependent manner. Conclusion The present study suggests that the piTreg cells have a stronger inhibitory effect on na ?ve T cell proliferation as compared with Terg cells from unpregnant mice , The differential activity of CD 4+CD25+Treg might be mediated by the paternal antigens during pregnancy .

BACKGROUND: Although some studies have been done on the functional change of cochlea in chickens during prolonged administration of kanamycin,few studies on ultrastructural changes in chicken cochlea have been reported.OBJECTIVE: To observe ultrastructural changes of the chicken basilar papilla following poisoning with prolonged administration of kanamycin.DESIGN: A completely randomized design and controlled observation.SETTING: Affiliated Xinhua Hospital, Shanghai Second Medical University.MATERIALS:The experiment was conducted in Xinhua Hospital Affiliated to Medical College, Shanghai Jiao Tong University from June 2001 to August 2003. Newly born Roman chickens (n=78), of either sex, provided by Shanghai Guixing Breeding Chick Farm, were used as subjects.METHODS: 200 mg/kg kanamycin was injected into muscles daily at day 3 after birth for 10 days. Then they were divided into 3 groups randomly:①typical application group: The chickens were applied with drugs no longer, and then killed at days 1, 3,7, 10 and 15, 6 chickens in each time phase. ②prolonged application group: 200 mg/kg kanamycin per day were injected into muscles continuously, and then killed at days 13, 17, 20, 25and 30, 6 chickens in each time phase. ③control group: The chickens were not treated with any drug. They were assigned into 3, 13 and 33 days groups with 6 chickens in each time phase. When the chickens were killed they were at the same age with the experime ntal animals at days 0, 10 and 30 of kanamycin treatment. All the experimental animals were studied with auditory brain-stem response (ABR) and scanning electron microscopy in chicken basilar papilla to observe ultrastructural change of cochlea, threshold, latency and amplitude of ABR wave I.MAIN OUTCOME MEASURES: ①Ultrastructural change of the chicken basilar papilla, and ② ABR result of chicken.RESULTS: A total of 78 Roman chickens were involved in the result analysis, without dropout. ①Outcome of ABR: Loss and recovery of chicken ABR threshold value was similar between within continuous administration for 20 days and administration for 10 days plus 10 days of recovery (drug withdrawal group). Twenty days after administration, ABR threshold significantly increased again. ②Outcome of scanning electron microscopy: At the end of 10-day kanamycin administration, hair cells in 40％ proximal chicken basilar papilla were destroyedand disappeared completely. Although continuous administration was performed, the hair cells began to regenerate and repair after damage. Within the 20-day continuous administration, the regenerated hair cells of basilar papilla developed maturity, which was mostly coincident with the administration for 10 days group. At day 25, regenerated hair cells of proximal basilar papilla were injured once again. At day 30, most of the regenerated hair cells were destroyed and disappeared.CONCLUSION: Prolonged administration of kanamycin obviously prevents the full repair of chicken basilar papilla damaged by kanamycin poisoning.

Objective To evaluate effects of camptothecin on the autophagy of HaCaT cells.Methods Some cultured HaCaT cells were divided into several groups to be treated with camptothecin at concentrations of 5,10,25,50,100 and 200 nmol/L,and 0.1％ dimethyl sulfoxide (DMSO) (control group),respectively.Cell counting kit-8 (CCK-8) assay was conducted to estimate the proliferative activity of HaCaT cells after 24-and 48-hour treatment,flow cytometry to evaluate cell apoptosis after 24-hour treatment,and Western blot analysis to measure the expression of autophagy-related proteins microtubuleassociated protein 1 light chain 3 (LC3) and p62.Some HaCaT cells were divided into 2 groups to be treated with 10 nmol/L camptothecin and 0.1％ DMSO for 24 hours,respectively.Then,indirect immunofluorescence assay (IFA) was performed to determine the LC3 expression.Results Camptothecin at low concentrations of 5 and 10 nmol/L had no significant effects on the proliferation and apoptosis of HaCaT cells.Compared with the control group,the cellular proliferative rates were significantly inhibited by (31.23 ± 1.00)％,(54.21 ± 8.10)％ and (66.75 ± 10.70)％ in the 50-,100-and 200-nmol/L camptothecin groups after 24-hour treatment respectively,and by (25.81 ± 5.99)％,(44.35 ± 5.32)％,(65.81 ± 8.28)％ and (73.23 ± 9.59)％ in the 25-,50-,100-and 200-nmol/L camptothecin groups after 48-hour treatment respectively (all P ＜ 0.001).After 24-hour treatment,the apoptosis rates were significantly higher in the 50-,100-and 200-nnol/L camptothecin groups (14.46％ ± 2.38％,19.15％ ± 1.59％,29.88％ ± 1.37％,respectively) than in the control group (3.80％ ± 0.13％,all P ＜ 0.001).After 24-hour treatment with 5 and 10 nmol/L camptothecin,the protein expression of LC3 Ⅱ was significantly up-regulated,while p62 protein expression was significantly down-regulated:IFA showed that the percentage of autophagosome-positive cells was significantly higher in the 10-nmol/L camptothecin group than in the control group after 24-hour treatment (36.67％ ± 4.55％ vs.6.23％ ± 0.92％,t =6.546,P =0.003).Conclusions Camptothecin at low concentrations of 5 and 10 nmol/L can induce autophagy of HaCaT cells,but has no obvious effects on cell proliferation and apoptosis.Camptothecin at concentrations of 50,100 and 200 nmol/L can inhibit cell proliferation,promote cell apoptosis,and decrease autophagy levels.
