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 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.

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 explore the association of the Thr241Met polymorphism of X-ray cross-complementing group 3 (XRCC3) gene with genetic susceptibility to aflatoxin B1(AFB-1)-related hepatocellular carcinoma (HCC)in Guangxi population.

METHODSWe conducted a hospital-based case-control study, including 257 HCC cases and 711 controls without cancers or liver diseases. The XRCC3 Thr241Met polymorphism was analyzed by PCR.

RESULTSThe XRCC3 genotypes XRCC3-Thr/Met or XRCC3-Met/Met were related with an elevated risk of HCC. The risk of HCC was associated with the number of mutant Met copies (adjusted OR were 2.20 and 8.56 for XRCC3-Thr/Met and Met/Met, respectively); moreover, there seemed to be combined effects for HCC risk between the variant genotypes and AFB1-DNA adduct levels from peripheral blood leukocytes (adjusted OR was 2.34 to 20.44, P < 0.01).

CONCLUSIONThese results suggested that XRCC3 polymorphism may be associated with the risk of AFB1- related HCC among the Guangxi population, and interacts with AFB1 exposure in the development of HCC induced by AFB1.

Pten gene is the first antioncogene with dual phosphatase activity discovered so far, pten gene regulates the cell cycle progress, apoptosis, metastasis and invasion of the tumor cells through negatively regulating the multiple signaling transduction pathways. Multiple myeloma (MM) is a malignant tumor occurring in terminal stage of B cell differentiation. The genetic changes are considered as the important factors in MM pathogenesis, among which the deletion of antioncogene is a critical genetic change. However, little is known about the genetic change of pten in MM. This review summarizes the research advance on pten in MM including structure of pten, mechanism of pten effect and correlation of pten with MM in order to provide some references for the investigating new gene target to treat the MM.

Thirst study was purposed to explore the genetic polymorphism of Chinese Zhuang population at HLA-Cw locus by sequence based typing (SBT). A total of 150 unrelated blood samples from Chinese Zhuang population were subjected to sequencing at exon 2, 3 and 4 of HLA-Cw gene in both directions by using SBT technique established by our laboratory. The purified products of sequencing reaction were run by means of electrophoresis on the ABI 3730 DNA Sequencer and the assignment of HLA-Cw genotype was accomplished by using the Assign 3.5 software. The consensus sequence at exon 2, 3 and 4 of HLA-Cw gene for each sample was imported into the Assign 3.5 software. The results showed that 33.33% of tested samples could obtain an unique genotype, genotype in 63.33% of tested samples with ambiguous results could be assigned by ruling out the rare alleles according to the NMDP Rare Allele List File; however, the final genotype in rest 3.33% of the detected samples could be defined when subjected to further confirmatory testing by PCR-SSP. In this detection 16 HLA-Cw alleles were identified, the common alleles with a frequency of > 10% were Cw*0304 > Cw*0102 > Cw*0801 > Cw*0702. The value for gene diversity (GD) was 0.9297, The frequency for Cw*01, 03, 07, 08, 12, 14 (Cw 1 allele group) and Cw*02, 04, 05, 06, 15, 16, 17, 18 (Cw 2 allele group) was 0.8967 and 0.1032, respectively, which indicated that the Cw 1 allele group is the dominant ligand for KIR in Chinese Zhuang population. 51 genotypes were determined and the distribution of genotype frequency was in line with Hardy-Weinberg principle. It is concluded that the obtained HLA-Cw allele frequency and its distribution characteristics of Chinese Zhuang population can provide valuable data in the studies of anthropology and the association of HLA-Cw with disease.
