Objective To develop psychosocial skills training module for schizophrenic outpatients.Methods Structured psychosocial skills training program, which were made according to community rehabilitation plan for schizophrenia, featured convenience and well operability. Subjects were 96 of 204 schizorenic outpatients in remission who were randomly assigned to receive psychosocial skills training combined medicine(observation group) or medicine only(control group) and followed up by 24 months. The changes during treatment were evaluated by positive and negative syndrome scale(PANSS), Social Disability Screening Schedule(SDSS) and patients' cognition function were also evaluated longitudinally. Results Relapse rate of control group (37%) is higer than observation group (17.7%, P＜0.01). After Last Observation Carried Forward(LOCF), control group showed higer scores than observation group on positive syndrome (8.34±2.04 vs 7.66±0.97), negative syndrome(9.15±1.97 vs 813±1.15), total score (37.64±5.58 vs 34.79±3.64) and Social disability (2.81±1.90 vs 2.07±1.47) (P＜0.01); observation group also showed a significant progress on cognition function(P＜0.05). Conclusion This trial demonstrated the efficacy of the easy-operating structured psychosocial skill training grogram in preventing relapse and improving social adoptive function for schizophrenia.

OBJECTIVETo explore the effect of Yixintai Granule (YG) on mRNA and protein expression levels of AQP2 in renal medulla of chronic heart failure (CHF) rabbits.

METHODSCHF rat model was established by ear marginal vein injection of adriamycin. Successfully modeled rabbits were divided into the model group, the high (8.4 g/kg), middle (4.2 g/kg), and low dose (2.1 g/kg) YG group, and the Furosemide group (2 mg/kg). Besides, a normal control group was set up. Equal volume of physiological saline was administered to rabbits of the model group and the normal control group by gastrogavage. YG at different doses was administered to rabbits of the 3 YG groups by gastrogavage. The intervention lasted for 4 weeks, once per day. After treatment the urine volume and pathomorphological changes of renal medulla tissue were observed. mRNA and its protein expression levels of AQP2 were detected.

RESULTSCompared with the normal control group, the urine volume decreased significantly, mRNA and protein expression levels of renal medulla AQP2 increased significantly in the model group (all P < 0.01). Compared with the model group, the urine volume increased significantly, and mRNA and protein expression levels of renal medulla AQP2 decreased significantly in all medicated groups (all P < 0.01). Compared with the low dose YG group, the urine volume significantly increased and the mRNA expression level of renal medulla AQP2 significantly decreased in the middle and high dose YG groups (all P < 0.01). The expression level of AQP2 protein significantly decreased in the high dose YG group (P < 0.01). Pathological changes of the renal medulla was the most obviously seen in the model group. But they were alleviated to various degrees in all medicated groups. They were more obviously attenuated in the middle and high dose YG groups.

CONCLUSIONYG could improve CHF possibly through down-regulating mRNA and protein expression levels of AQP2 in renal medulla, and elevating the urine volume.

Objective To analyze clinical diagnosis and management of 5 patients with actinomycete keratitis.Design Retro- spective case series.Participants 5 patients (5 eyes) with actinomycete keratitis.Methods The clinical features and microbiologic da- ta of 5 culture-proven cases of actinomycete keratitis recorded between October 2004 to March 2006 were analyzed.Main Outcome Measures clinical characteristics,isolations identification,drug susceptibility test and treatments.Results All patients were males and farmers.Of the 5 cases presented in this study,4 cases were followed by minor trauma as a predominant risk factor,and were pre- sented by a chronic progressive corneal ulcer with a wreath pattern of infiltrate.The diagnosis of all cases was based on laboratory in- vestigations,by which 4 cases of nocardia and one case of streptomyce were identified.A variable drug sensitivities were presented in nocardia isolates,which including TMP-SMZ,amicasin,gentamicin and fluorine-quinolones.Conclusions Nocardia keratitis is mainly followed by a minor trauma.It is identified predominantly by laboratory investigations.Tropical and systemically sensitive biotic are the initial choice,while debridement and amnionic transplantation could be an effective alternative.

OBJECTIVETo investigate the changes in the serum content of immunoreactive calcitonin (iCT) after burns or inhalation injury, and to explore its diagnostic significance.

METHODSTwenty-four dogs were randomized into 4 groups, i. e. A (n = 6, with moderate degree inhalation injury) , B ( n = 6, with severe inhalation injury), C (n = 6, with most severe inhalation injury) and D (n = 6, with severe burns) groups. The serum content of iCT and blood gas analysis before and after injury were determined at different time points. The degree of inhalation injury was determined with fibrobronchoscopic examination at 6 post-inhalation injury hour (PIH).

RESULTS(1) Fiber bronchoscopic examination showed that the degree of inhalation injury in each group was coincident with the anticipation. (2) The serum content of iCT in each group at 1 PIH was obviously higher than that before injury, and it was evidently higher in A, B and C groups than that in D group at 4 PIH. The peak value of iCT in group A at 24 PIH was (453+/-224) ng/L, and it increased gradually in B and C groups at 48 PIH. The serum content of iCT increased continually from 2 PIH on, and it reached (125+/-41) ng/L at 48 PIH. (3) Compared with PaO2 value before injury (109+/-8) mmHg, there was no obvious difference of the PaO, in A and D groups. PaO2 value in B and C group began to descend continually at 8 PIH (65+/-6) mmHg, and that in C group began to descend at 4 PIH (71+/-9) mmHg. PaCO2 value in C group began to increase at 24 PIH(52+/-11) mmHg when compared with that before injury(38+/-5 ) mmHg.

CONCLUSIONThe changes in the serum level of iCT within 8 PIH occurred much earlier than PaO2 and PaCO2, thus it has the same diagnostic significance as fibers bronchoscopic examination.

OBJECTIVETo identify a novel human leukocyte antigen (HLA) allele by cloning and sequence-based typing in Chinese population, and analyzing the sequence of the introns 1 and 2.

METHODSThe routine HLA-A, -B, -DRB1 low resolution genotyping for stem cell donor from Guangdong province was performed with polymerase chain reaction-sequence specific oligonucleotide probes (PCR-SSOP). An unknown HLA-DRB1 allele was initially detected by HLA typing. Genomic DNA of the proband was amplified by using HLA-DRB1 locus group-specific primer, the amplified product was cloned, sequenced, and compared to the closest DRB1*120201 allele and the closest intron sequence of the DRB1*030101 allele.

RESULTSThe sequencing results showed that a normal DRB1*080302 and a novel DRB1*1218 variant allele were identified. The sequence of the novel allele has been submitted to GenBank (FJ481086). The novel allele had 1 nucleotide substitution of the closest matching allele HLA-DRB1*120201 at nt262(G-->C) in exon 2,resulting in an amino acid change from Glu(GAG)-->Gln (CAG) at codon 59.The intron 2 sequence is identical between the novel HLA-DRB1*1218 and DRB1*030101, but there are 12 nucleotides substitution in intron 1.

CONCLUSIONA novel HLA allele was confirmed by cloning and sequence-based typing in Chinese. It was officially designated as HLA-DRB1*1218 by WHO Nomenclature Committee.

OBJECTIVETo investigate the changes in cellular apoptosis of Peyer's patches in severely scalded mice, and to explore its role in the pathogenesis of gut barrier damage.

METHODSForty BALB/c mice were randomly divided into normal control, 12 post-scald hour (12PSH), 24PSH and 72PSH groups, with 10 in each group. The mice in all PSH groups were inflicted with 20% TBSA full-thickness scald on the back. The mice in all the groups were sacrificed at different time points, and Peyer's patches were harvested from all the mice for HE staining, DNA gel electrophoresis, and flow cytometry ( FCM) examination with FITC conjugated Annexin-v and propidium iodide( PI) staining of cells.

RESULTSHE staining revealed that there were relatively abundant apoptotic cells scattering in Peyer's patches of scalded mice . DNA electrophoresis of Peyer's patches revealed typical " ladder" pattern at all indicated time points in scalded mice. Apoptotic percentage of detached Peyer's patches cells in control and scalded group were (4. 9+/-2. 1)% , (26.7+/-3. 1)% , (21.6 +/-4.0)% ,(12. 8 +/-2.0)% , respectively, and the percentage reached the peak at 12 PSH.

CONCLUSIONApoptosis is a principle modality of cell death of small intestinal Peyer's patches lymphocytes in severely scalded mice, and it might contribute to immunity barrier failure of intestinal wall after severe thermal injury.

OBJECTIVETo investigate the effects of glutamine enriched enteral feeding on immunoregulation in burn patients.

METHODSTwenty burn patients were randomly divided into enteral nutrition (EN) group and enteral immune nutrition (EIN) group, with 12 patients in each group. Patients in EN group received a standard enteral formula, while those in EIN group received an enteral formula enriched with glutamine after hospital admission. Nutritional support was continued for 10 days. Blood samples were obtained to determine plasma level of total protein (TP), albumin (ALB), prealbumin (PAB) and transferrin (TF) at 1, 4, 7, 10 post-burn days (PBD). At the same time the concentration of immunoglobulin (IgA, IgG and IgM) were determined, the percentage of CD3+, CD4+, CD8+ subpopulations of T lymphocytes, and the ratio of CD4+/CD8+ were determined by FCM.

RESULTS(1) There were no obvious difference of the plasma level of TP, ALB, TF, CD3+, IgM between the two groups at each time-point (P > 0.05). (2) The plasma PAB contents in EIN group were significant higher than that in EN group on 4 PBD [(90 +/- 14 vs 60 +/- 15) mg/L, P < 0.05], 7 PBD [(92 +/- 16 vs 64 +/- 13) mg/L, P < 0.05] and 10 PBD [(106 +/- 21 vs 72 +/-16) mg/L, P < 0.05]. (3) The percentage of CD4+ subpopulation and ratio of CD4+/CD8+ in EIN group were obviously higher than those in EN group on 7 PBD [CD4+ (55 +/- 5 vs 45 +/- 5)%, CD4+/CD8+ (1.92 +/- 0.31 vs 1.53 +/- 0.27)%, P < 0.05] and 10 PBD [CD4+ (56 +/- 5 vs 49 +/- 5)%, CD4+/CD8+ (2.36 +/- 0.36 vs 1.72 +/- 0.42), P < 0.05]. (4) The concentration of IgA and IgG in EIN group were markedly higher than that in EN group on 7 PBD [IgA (2.8 +/- 0.6 vs 2.2 +/- 0.5) g/L, IgG (12.1 +/- 1.3 vs 9.8 +/- 1.2) g/L, P < 0.05] and 10 PBD [IgA (3.1 +/- 0.6 vs 2.5 +/- 0.5) g/L, IgG (14.2 +/- 1.3 vs 10.4 +/- 1.3) g/L, P < 0.05].

CONCLUSIONThese findings suggest that glutamine enriched enteral feeding can improve nutritional status by promoting the synthesis of IgA, IgG, and increasing the PAB concentration, and corrected immunologic dysfunction in burn patients.

OBJECTIVETo study the histological change of microscrew-bone interface, detect the relative cytokine of gingival crevicular fluid, and explore the impossible mechanism of peri-implantitis.

METHODSFour male Beagles were collected. Randomly select one side of animals jaw as the experimental group to induce the peri-implantitis, and another side as the control group. Four microscrews were implanted on each side. In the 1st, 2nd, 3rd, 4th weeks after implantation, collect peri-implant sulcular fluid (PISF) and detect tumor necrosis factor-alpha (TNF-alpha) levels before sacrificed, and the harvest tissue were observed in histological ways.

RESULTSAccording to the extension of time after implantation, the experimental group showed visible progress of interface destruction: 1st week after implantation showed large numbers inflammatory cells collected at the neck but did not undermine the cortical bone; 2nd week after implantation, cortical bone were observed angular absorption; Bone resorption continued to develop and at the 4th week, bone resorption were enlarged to the second thread of microscrew and the interface was filled with a large number of collagen fibers.

CONCLUSIONThe destruction of interface began at the neck of microscrew, and the further development was along the interface in depth. Both microscrews with peri-implantitis and the healthy controls showed the presence of TNF-alpha. Inflammation accumulation might trigger the up-regulation of TNF-alpha level, and the onset of inflammation would enhance the up-trend.
