OBJECTIVETo explore lupus nephritis (LN) patients' monocyte chemotactic protein 1 (MCP-1) and urinary IP-10 (ulP-10) levels, the correlation between each clinical activity index and rheumatism syndrome, thereby proving objective evidence for microscopic typing of rheumatism syndrome.

METHODSTotally 60 LN patients were assigned to the rheumatism group (31 cases) and the non-rheumatism group (29 cases). Besides, 20 healthy volunteers were recruited as the normal control group. Clinical data and renal pathology were collected, and urinary levels of MCP-1 and IP-10 detected by ELISA. The correlation between rheumatism syndrome and each activity index as well as manifestations of clinical activities was comprehensively analyzed. Results (1) Patients in the rheumatism group were more liable to occur fever, serositis, edema, and hypertension (P<0.05). (2) Compared with the non-rheumatism group, patients in the rheumatism group exhibited much higher levels of 24 h protein quantification and blood urea nitrogen, higher levels of uMCP-1 and ulP-10. Microscopic hematuria, anti-ds-DNA, anti-Sm, the positive rate of AnuA, scores of SLEDAI and BILAG were higher in the rheumatism group than in the non-rheumatism group (P<0.05). Levels of plasma albumin and complement C3 were lower in the rheumatism group than in the non-rheumatism group (P<0.05). (3) The average activity index (AI) of the renal pathology was higher in the rheumatism group than in the non-rheumatism group. The most frequent pathological type of rheumatism group was type IV of LN.

CONCLUSIONSMore severe renal damage and immune abnormality occurred in LN patients of rheumatism syndrome. Rheumatism syndrome is closely correlated to clinical activity indices.

Insulin receptor substrate(IRS)-1 and IRS-2 expression levels of liver tissues and skeletal muscle in intrauterine growth retarded(IUGR)rats were investigated by RT-PCR and immunohistochemistry.An IUGR animal model was established by maternal nutrition restriction during pregnancy.IRS-2 expression level of liver tissue and IRS-1 expression level of skeletal muscle in IUGR rats at 0 and 3 weeks old were significantly lower than those in normal rats at the same age respectively,and insulin resistance was induced in IUGR,and these findings might be the molecular mechanisms susceptible to metabolic syndrome in IUGR rats.

To observe the clinical outcome of implanting AcrySof lQ Toric intraocular lens to correct corneal astigmatism in cataract surgery, and to evaluate the result and rotational stability of AcrySof lQ Toric after cataract surgery.
●METHODS: A retrospective study of 26 eyes in 21 cataract patients with corneal astigmatism. All patients implanted AcrySof lQ Toric intraocular lens. The preoperative and postoperative uncorrected visual acuity ( UCVA ), best corrected visual acuity ( BCVA ), preoperative corneal astigmatism, anticipated residual astigmatism, total astigmatism, postoperative residual astigmatism and Toric lens axis were detected and measured.
●RESULTS: All patients' visual acuity and best corrected visual acuity improved significantly. The mean refractive cylinder decreased significantly after surgery from (2. 05± 0. 57)D to (0. 55±0. 33)D (t = 13. 574, P<0. 05). There was no significant difference between preoperative ( 0. 47 ± 0. 19)D and postoperative corneal astigmatism (t = 1. 149, P > 0. 05 ). Three months after surgery, there was no significant difference between preoperative (2. 01±0. 58)D and postoperative (-1. 89±0. 53) D corneal astigmatism (t =1. 908, P> 0. 05). The rotation of intraocular lens were <20°, the mean rotation was 3. 65°±2. 86°.
●CONCLUSlON: The AcrySof lQ Toric lens make cataract patients enjoy the better UCVA including good rotational stability in the correct of corneal astigmatism. The AcrySof lQ Toric implantation is an effective option for the correct of preexisting corneal astigmatism in cataract surgery.

Vibrio parahaemolyticus has been considered as one of the most important foodborne bacterial pathogens.The loop-mediated isothermal amplification(LAMP) that amplifies DNA with high specificity and rapidity under an isothermal condition was applied for rapid detection of this pathogen for the first time.A set of four primers,two outer and two inner primers,was designed specifically to recognize the thermolabile hemolysin gene(tlh) of V.parahaemolyticus.The LAMP reaction mix was optimized.The most optimal reaction temperature and time of the LAMP assay for the tlh gene were 60℃ and 60min,respectively.Genomic DNAs from 28 bacterial strains including 14 V.parahaemolyticus strains were amplified using LAMP,and no amplicon was observed in other bacterial strains.The detection limit of this LAMP assay was around 90 fg of V.parahaemolyticus genomic DNA and 24 colonies forming units for pure cultures.In addition,this method was applied to detect artificially contaminated food samples,and the detection limit was 89 cfu/g for non-cultured artificially contaminated food samples.These results suggested that detection of V.parahaemolyticus by LAMP is an effective and low-cost procedure with high specificity and sensitivity that requires no specialized equipment.This assay is expected to become a valuable tool for rapid detection and identification of V.parahaemolyticus.

Viable but non-culturable state in bacterial cells as received uncultured microorganism has be- come the fundamental research issues in medical microbiology, epidemiology, general microbial ecology and sanitation quarantine since it was put forward in 1982. When in this state, bacterium are no longer able to grow and form colonies on conventional culture media, but maintain their patheogenicity, may become latent infection escaping detection to threaten enviroment and human security. With the development of modern molecular biology technique and metagenomics, it provide new research method and opportunity for uncul- tured microorganism in the environment. Recently, with the application of the metagenome technique, ge- netic fingerprinting technical etc, it becomes more and more popular. Simultaneously, along with this state become maturity in the laboratory. It provides a new research route for development and exploitation the uncultured microorganism.

Abstract?AlM:To discuss the feasibility of using the visual quality analyzer KR - 1W to guide the relatively personalized aspheric intraocular lens ( lOL ) implants to make the whole eye spherical aberration close to 0. 1μm.?METHODS: ln this prospective case series study, the corneal spherical aberration with 6mm aperture of 73 patients (100 eyes) was measured with KR-1W Visual Function Analyzer 1d before surgery. For the sake of the whole postoperative spherical aberration were close to 0. 1μm, 9 cases ( 16 eyes ) with corneal spherical aberration <0. 15μm were implanted Sofport Advanced Optic lOL, named AO group;45 cases ( 57 eyes ) with corneal spherical aberration 0. 25~0. 3μm were implanted AcrySof lQ lOL, named lQ group;19 cases (27 eyes) with corneal spherical aberration > 0. 35μm were implanted Tecnis ZA9003 lOL, named Tecnis group. Aspherical lOL was implanted after phacoemulsification through a cornea 2. 75mm incision without suture. Uncorrected visual acuity, beat corrected visual acuity, spherical aberration of the whole eye and jnternal optics (mainly lOL) at 6mm pupil diameter were examined at 3mo postoperatively. The relevant data were analyzed using t-test and variance analysis.?RESULTS: The whole ocular spherical aberration at 6mm pupil diameter in all postoperative were 0. 084 ± 0. 032μm;in Tecnis group, the data were 0. 091 ± 0. 021μm;in AO group, the data were 0. 0814-0. 013μm;lQ group were0. 093 ± 0. 042μm. There was no significantly different between the predicted value and actual value of ocular spherical aberration at 6 mm pupil diameter in all postoperative ( t = 1. 932, P = 0. 061 ) and in the three groups. The difference value in the predicted values of the preoperative spherical aberrations of the whole eye and the actual values after surgery was 0. 013±0. 041μm; there was no statistically significant difference ( F=2. 537, P=0. 091 ) . Respectively compared the uncorrected visual acuity and besta corrected visual acuity among three groups of postoperative, no significant difference were found (F=0. 897, P=0. 421;F=1. 423, P=0. 097).?CONCLUSlON: Personality selection of aspheric lOL based on preoperative corneal spherical aberration of patients is feasible and produces satisfactory target postoperative total spherical aberration.

Objective To compare the diagnostic value of renal ultrasound scan (RUS) and 99Tcmdimercaptosuccinic acid (DMSA) renal scintigraphy in children with acute pyelonephritis (APN). Methods In all, 165 children with initial clinical diagnosis of APN, aged from 1.5 months to 11 yrs ( median 20 months), were included in the study, all of which were examined with RUS and DMSA renal scientigraphy. The diagnosis with DMSA renal scientigraphy results was taken as the standard reference to evaluate the diagnostic sensitivity and specificity of RUS. Results Of 99 out of all 330 kidneys that were found abnormal on DMSA renal scientigraphy, 31 were abnormal on RUS. Of the rest normal kidneys on DMSA scans renal scientigraphy, 4 were abnormal on RUS. Thus diagnostic sensitivity of RUS for APN was 31.3%(31/99) and specificity was 98.3% (227/231). Conclusions Although RUS provides with high diagnostic specificity for children with APN, its low sensitivity may underestimate the clinical evaluation of APN.More often than not, 99Tcm-DMSA renal scientigraphy is a clinical necesscity for the definite RUS diagnosis.
