ObjectiveTo investigate the effect on improving immune function by hemofiltration combined with hemoabsorption in septic patients with low human leukocyte antigen DR (HLA-DR) expression.Methods A prospective randomized controlled trial was conducted. Sixty sepsis patients aged over 18 years, with HLA-DR expression lower than 30% were enrolled, and they were randomly divided into experimental group and control group, n = 30 in each group. The patients were treated with standard operating procedure for sepsis, and hemofiltration combined with hemoabsorption were added in addition in the experimental group within 1-3 days. The continuous veno-venous hemofiltration (CVVH) mode was performed, with former dilution volume 4 L/h, and the hemofilter HF2000 was carried out with blood absorber HA-330H. The expression of HLA-DR in peripheral blood mononuclear cells was determined before the treatment and 3, 5, 7 days after treatment. Acute physiology and chronic health evaluationⅡ(APACHEⅡ) score, duration of mechanical ventilation, length of intensive care unit (ICU) stay, and 28-day survival rate were evaluated in both groups.Results The HLA-DR expression before treatment in experimental group and control group was both lower than 30%, and there was no statistical difference [(25.9±7.3)% vs. (26.4±6.7)%,P>0.05]. The HLA-DR expression at 3, 5, 7 days after treatment in experimental group was gradually increased, and it was significantly higher than that of the control group [3 days: (38.9±8.6)% vs. (29.3±7.1)%, 5 days: (42.7±9.2)%vs. (31.4±6.5)%, 7 days: (40.9±8.5)% vs. (29.4±6.7)%, allP< 0.05]. There was no significant difference in APACHEⅡ score before treatment between experimental group and control group (22.4±5.3 vs. 21.7±6.2,P>0.05). APACHEⅡ score at 3, 5, and 7 days after treatment was gradually decreased in experimental group, and it was obviously lower than that of the control group (3 days: 18.6±3.6 vs. 20.5±4.3, 5 days: 15.8±3.9 vs. 21.1±4.4, 7 days: 14.9±4.2 vs. 19.8±3.7, allP< 0.05). Compared with the control group, the duration of mechanical ventilation (days: 13.3±3.4 vs. 19.8±3.7,t = 6.432,P = 0.003) and length of ICU stay (days: 20.7±3.9 vs. 26.8±4.7,t = 5.452, P = 0.006) in experimental group were significantly shortened, and the 28-day survival rate was significantly elevated (83.3% vs. 73.3%,χ2 = 3.121,P = 0.016).Conclusion Hemofiltration combined with hemoabsorption can improve the expression of HLA-DR in sepsis patients with low expression of HLA-DR, and it can improve immune function and prognosis of sepsis patients in certain degree.

Objective To analyze the clinical features and causes of benign paroxysmal positional vertigo(BPPV).Methods The clinical data of 521 patients with BPPV were collected.The percentage of patients with BPPV in all the outpatients with dizziness and vertigo,the clinical characteristics of BPPV,and the prevalence of comorbidity with migraine were analyzed.Results BPPV accounted for 35.7% of patients with vertigo and 12.1% of patients with dizziness.Among the 521 patients with BPPV,158(30.3%)were male and 363(69.7%)were female,with an average age of(57.5?12.8)years old(20 to 93 years old).Right semicircular canals were involved in 323 cases(62.0%),and left semicircular canals in 187 cases(35.9%).The latency period of nystagmus of vertical canals was(3.22?2.37)s,and time of persistence was(8.31?7.98)s.The latency period of nystagmus of horizontal canals was(2.33?1.50)s,and the time of persistence was(14.77?11.40)s.There were significant differences in the latency period of nystagmus and time of persistence between the vertical and horizontal canals(P=0.001 and P=0.000).Fifteen patients(2.9%)had a history of head trauma and 39(7.5%)were complicated with migraine.Conclusion BPPV is prevalent in patients with dizziness and vertigo,and misdiagnosis and missed diagnosis should be avoided.

Objective To examine the relationship of heparanase expression and age, clinicopathological features and prognosis of ovarian cancer patients. Methods Forty-one ovarian cancer specimens, from the patients admitted to the 3 hospitals of our university during the period of Jan 2003 to Nov 2005, were of serous carcinoma (22 cases) and mucous carcinoma (10 cases) and other types (9 cases), of which 16 were well and moderately differentiated and 25 poorly differentiated. Ten specimens of normal ovarian tissues were taken as normal controls. The heparanase expression was detected in all specimens and its relationship with histologic type, differentiation, FIGO stage and prognosis of the ovarian cancer was analyzed. Results The positive rate of heparanase expression was 80.48% in ovarian cancer tissues and 10.00% in normal ovarian tissues (P

To reveals the effects of tree species on polysaccharides content of epiphytic Dendrobium officinale. The polysaccharides content of D. officinale attached to living tress in wild or stumps in bionic-facility was determined by phenol-sulfuric acid method. There were extremely significant differences of polysaccharides content of D. officinale attached to different tree species, but the differences had no relationship with the form and nutrition of barks. The polysaccharides content of D. officinale mainly affected by the light intensity of environment, so reasonable illumination favored the accumulation of polysaccharides. Various polysaccharides content of D. officinal from different attached trees is due to the difference of light regulation, but not the form and nutrition of barks.

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.

AIM: To compare the difference of A-scan and lOL Master in intraocular lens power measurement.
●METHODS:Two hundred and twenty-six patients (230 eyes) with age-related cataract were included in the study. Before surgery, axial length was measured by A-scan and lOL Master respectively and corneal curvature was measured by auto refractometer. lntraocular lens power was calculated according to the SRK-T formula. Corneal curvature was measured by auto refractometer and the refractive outcome was performed by phoropter three months after cataract surgery.
●RESULTS:The mean axial length was (23. 48 ± 1. 94) mm measured by A-scan and (23. 75±1. 96) mm measured by lOL Master. There was significant difference between them ( P < 0. 05 ). After random grouping, the preoperative and postoperative mean corneal curvature in A-scan group was (43. 94±1. 81) D and (43. 98±1. 87) D respectively. There was no statistically significant difference between them (P>0. 05). And the results were (44. 10 ± 1. 57 ) D and ( 44. 11 ± 1. 58 ) D in lOL Master group. There was no significant difference between them (P>0. 05); The mean absolute refractive error (MAE) in A-scan group was ( 0. 47 ± 0. 27 ) D and in lOL Master group (0. 41±0. 19) D. The difference was significant (P<0. 05).
●CONCLUSION: lOL Master is proved to be slightly more accurate than A-scan for lOL power calculation.
