Objective To study the clinical manifestation,treatment and prognosis of patients with primary Sjgren′s syndrome and renal tubular acidosis.Methods Sixty patients who were diagnosed as pSS complicated with RTA during the last 13 years were retrospectively analyzed and followed up for 7 5 years on average.Results Distal renal tubular acidosis ( n =53,83 3%) was much more frequeut than the proximal one ( n =7,11 7%).Hypokalemic paralysis,diabetes insipitus,and calcification of the renal tissue appeared in 49 patients (92 4%).Glomerular lesions were found in 12 of the 15 patients who underwent kidney biopsy.Renal insufficiency was developed subsequently in 4 out of 5 patients with glomerular sclerosis.Abnormal serum creatinine was detected in 11 patients (18 3%),and in 7 of them it persisted 11 5 years on average after the onset of RTA.Two of them died from renal failure and 1 received hemodialysis.Hypergammaglobulinemia was more obvious in the patients with renal insufficiency than those without ( P

Objective To investigate the clinical manifestations, immunological features and prognosis of primary Sj(o)gren's syndrome(pSS) with anticentromere antibodies(ACA). Methods Sixty pSS patients with ACA in our hospital between 1985 and 2006 were screened retrospectively and compared with those without ACA. Results The mean age at the onset of pSS with ACA was higher than that of those without ACA[(48±11)yr vs(41±12)yr,P=0.000].There was no difference in sex ratio,dry mouth.dry eyes and positive salivary gland biopsy between the two groups(P＞0.05).Compared with those without ACA,patients with ACA presented a higher prevalence of liver involvement(68.3%vs 37.0%,P=0.000),while a lower prevalence of renal involvement(13.3%vs 30.9%,P=0.009), neuropathy(1.7% vs 11.5%,P=0.025)and hypergammaglobulinemia(20.8%vs 45.7%,P=0.002). The difference was not significant between the two groups in Raynaud's phenomenon,articular involvement,myositis,hematologic involvement,lung involvement,and thyroiditis. While both groups showed the same prevalence of antinuclear antibody(ANA),the patterns of ANA-IF were different and the discrete speckled pattern was the most freqent in patients with ACA and occurred in 61.7%. Different from those without ACA,patients with ACA presented a lower prevalence of anti-SSA,anti-SSB, rheumatoid factor, and antiU1 RNP,while showed a higher prevalence of antimitochondrial antibodies(AMA) and AMA-M2. The most frequent cause of death was the complications associated with cirrhosis,notably bleeding varices(3/5 cases). Conclusion Patients with ACA present a high risk of liver involvement. Because of the remarkable difference in the mean age of disease onset and also differences in systemic damage, immunological and antibody features, pSS with ACA may be a special subtype of pSS.

Insertion of foreign genes into the genome map of Chinese herb always produces the intended beneficial effects, but also the unintended effects. Analysis of genomic function and metabolic end products based on the principle of substantial can reveal the influence on the quality of herbs, which is able to provide valuable refer-ence for the following evaluation on pharmacology and toxicology.

Objective:To optimize the determination technology for the total amino acids in Runing pills. Methods:The process was optimized by L9 (34 ) orthogonal design using the hydrolysis temperature, hydrolysis time and hydrochloric acid concentration as the evaluation factors,and the content and yield of total amino acids as the evaluation indices. Results: The optimal determination condi-tions were as follows:the hydrolysis temperature was 110℃, the hydrolysis time was 22 h and the hydrochloric acid concentration was 6 mol·L-1 . Conclusion:The optimal determination technology can be applied in the total amino acids from Runing pills,which pro-vides the basis for the further research of Runing pills.

This study was aimed to collect relevant provisions of bulging disease medical records in the Ming and Qing dynasties to excavate the syndrome differentiation, drug law and medication frequency analysis. A database was established to analyze relevant provisions. The results showed that the syndromes of liver stagnation and spleen deficiency, dampness-heat accumulation, spleen-yang deficiency are the most common type. The mainly used drugs are from the category to eliminate dampness and water, and to tonify the deficiency. The top three used drugs are poria, atractylodes, and dried citrus peel. It was concluded that medications used in the Ming and Qing dynasties were mainly targeted to the disordered zangfu-organ, which was mainly about the spleen and the stomach. The syn-drome differentiation is the mixture of deficiency and excess. And deficiency is the main part. The medication should combine tonification and reducing. And tonification should be paid attention to. The syndrome differentiation and treatment should be coordinated and the primary and secondary aspect should be identified. These rules provide ref-erence effect for the clinical practice and scientific research of bulging disease treatment.

Objective To investigate the effect of berberine on the polarization of mice RAW264.7 macrophages induced separately by lipopolysaccharide (LPS) and interleukin-4 (IL-4). Methods Mice RAW 264.7 macrophages cultured in vitro were divided into model group, medication group, and blank control group. Both model group and medication group were given either LPS (in final dose of 100 ng/mL) or IL-4 (in final dose of 10 ng/mL). Additionally, the medication group was treated with berberine in final dose of 20 μmol/L. The blank control group was given the same volume of phosphate buffered saline ( PBS). Real-time fluorescence quantitative polymerase chain reaction (PCR) was used to detect the mRNA expression of arginase-1 (Arg-1), inducible nitric oxide synthase ( iNOS) , suppressor of cytokine signaling2 ( SOCS2) and SOCS3. Enzyme-linked immunosorbent assay (ELISA) was used to determine the contents of tumor necrosis factor alpha (TNF-α) and IL-10. Results The content of TNF-αand the mRNA expression levels of iNOS and SOCS3 in macrophages induced by LPS were increased, and then were down-regulated by berberine (P<0.05 or P<0.01) . The content of IL-10 and the mRNA expression level of Arg-1 in macrophages induced by IL-4 were increased, and then were down-regulated by berberine ( P<0.05), but berberine had no effect on the mRNA expression level of SOCS2 ( P>0.05). Conclusion Berberine has an effect on inhibiting the M1 and M2 polarization of macrophages in vitro, suggesting that berberine may play a regulatory role in the dynamic balance of M1/M2.

Objective To observe the anti-inflammatory effects of three kinds of aconine from Radix Aconiti Lateralis Preparata ( Fuzi) on macrophages, as well as the effects of their combination with sinomenine. Methods The effect of three monoester alkaloids from Fuzi, benzoylaconine ( BAC) , benzoylmesaconine ( BMA) and benzoylhypaconine ( BHA) , on RAW264.7 cells proliferation was detected by cell counting kit 8 (CCK8) in vitro. RAW 264.7 macrophage cells were stimulated by lipopolysaccharides (LPS) and then treated with different concentrations of BAC, BMA, and BHA. Tumor necrosis factor alpha ( TNF-α) and interleukin 6 (IL-6) secreted by RAW264.7 cells were measured by enzyme-linked immunosorbent assay (ELISA) . The anti-inflammatory effects of three monoester alkaloids combined with sinomenine were evaluated by Zhengjun Jin Q method. Results The concentrations of TNF-α and IL-6 secreted by LPS-stimulated RAW264.7 cells were increased significantly ( P<0.01) , and then were inhibited by BAC ( 20, 30 μmol/L) , BMA ( 40, 80, 160μmol/L) and BHA ( 40, 80, 160 μmol/L) significantly ( P<0.01) . Antagonistic effects were present when 30 μmol/L of BAC or 160 μmol/L of BMA or 160 μmol/L of BHA was respectively used together with 100 or 300 μmol/L of sinomenine (Q<0.85). Conclusion The three kinds of monoester alkaloids from Fuzi exert anti-inflammatory effect on macrophages, and the effective dose of BAC is lower than that of BMA and BHA. The combination of BAC, BMA or BHA at the analyzed dosage with sinomenine has antagonistic effect.
