Objective To analysis the varying degrees of the M protein staining after immunofixation electrophoresis(IFE)and study its applications in clinical diagnosis.Methods 196 cases of clinical serum samples were tested by using IFE,we analyzed the positive electrophoretic bands of M protein and performed statistical analysis by using SPSS17.0.The M proteins were analyzed ret-rospectively.Results 103 patients were diagnosed with monoclonal gammopathy in 196 patients with positive M protein bands,in-cluding 96 cases of multiple myeloma(MM)and 7 cases of other monoclonal gammopathy;93 patients were non-monoclonal gam-mopathy.By analyzing the M band staining in different clinical groups,we found that M bands were mainly with dense and thick staining in monoclonal immunoglobulin group,the dense staining rate of MM was 90.6%,and the difference between MM and the other monoclonal gammopathy was not significant(P >0.05).In contrast,M bands were in light and narrow staining in non-mono-clonal immunoglobulin group,the rate of which was 25.8%,the difference between non-monoclonal immunoglobulin group and monoclonal immunoglobulin group was statistically significant(P <0.01).The proportion of allelic band in MM,other monoclonal gammopathy,non-monoclonal gammopathy were 39.6%,28.6% and 2.2% respectively,the differences were statistically significant (P <0.01).Conclusion The M band,accompanied by allelic band in IFE staining,is helpful in the diagnosis of monoclonal gam-mopathy,especially MM.The appearance of M protein provides early warning of monoclonal gammopathy.

Objective To immunize BALB/c mice with type 3 musearinic acetylcholine receptor polypeptide (M3RP) and to evaluate the role of M3RP in SS. Methods Four-week-old BALB/e mice were immunized with M3R polypeptide 213-228 (M3RP) on days 0, 14, 35, 56, and were re-immuniged on days 65, 84, 105, and one mouse was killed every 2 to 3 weeks. The mice of the control group were immunized with submaxillary gland homogenate, GST, and PBS. The animals were analyzed for the presence of anti-SSA,anti-SSB, RF, ANA, anti-a-fodrin and anti-M3RP in sera by immunofluorescenee or ELISA. The cytokines of IFN-γ IL-2 and IL-10 were measured with ELISA. Salivary glands were examined by H＆E staining and immunohistochemical analysis. Volume of water drinking by each groups were calculated. Results BALB/e mice immunized with M3RP and submaxillary gland homogenate developed an immune response directed against M3RP, α-fodrin and ANA, but no antibodies against SSA, SSB and RF were found. Furthermore, lym-phocytic infiltrates in the salivary glands of immunized animals were observed 50 days after first immunization of M3RP and submaxillary gland homogenate. The serum IFN-α in mice of M3RP, submaxillary gland ho-mogenate, GST and PBS was (62±6), (89±5), (30±5) and (19±6) pg/ml respectively, and IL-2 was (12.6±1.6), (19.8±0.4), (3.9±0.9), and (4.9±1.1) pg/ml respectively (P<0.05). No difference was found in the level of serum IL-10 among the four group. Expression of α-fodrin was found only in submaxillary gland in M3RP and submaxillary gland homogenate groups of mice, but not in PBS and GST controls when studied by immunohistochemical analysis. Conclusion These results suggest that BALB/c mice immunized with M3RP are reminiscent of human SS, and M3RP as an autoantigen participates the development of SS.

Objective To study the relationship between elevated serum level of immunoglobulin A (IgA) and other abnormality in immunological parameters in patients with primary Sjogren's syndrome (pSS)and those with viscera involvement based on determinations of serologic,other laboratory and clinical features.Methods Serum IgA level of 108 patients with pSS,seven males and 101 females with an age of 30～78 years and length of disease course of 0.2～20.0 years,was detected by turbidimetry.Clinical and laboratory parameters in patients were compared between different groups.Remits Elevated serum IgA level was found in 48 (44.4%) of 108 patients with pSS.Elevated erythrocyte sedimentation rate(ESR) was found in 91.7 percent of those with elevated sertum IgA and 63.3 percent in those with normal IgA(P<0.05).Serum positivity of rheumatoid factor(RF) was significantly higher in those with elevated serum IgA (70.8%)than those with normal IgA (48.3%,P<0.05).Pulmonary interstitial fibrosis could be found in 22.9 percent of those with elevated serum IgA,and in 8.3 percent of those with normal IgA(P<0.05).Occurrences of primary biliary cirrhosis and autoimmune hepatitis were higher in those with elevated serum IgA than in those with normal IgA,but not reaching statistical significance.Conclusion Serum IgA level misht play an important role in occurrence and development of pSS,and could be used as an indicator reflecting activity and severity of the disease,as well.

ObjectiveTo explore the clinical therapeutic effect of treating cervical vertigo induced by atlantoaxial joint malposition with manipulation.MethodsForty cervical vertigo cases induced by atlantoaxial joint malposition and diagnosed by palpating, X-ray examination, were treated with fixed-point manual reduction.ResultsThirty-one cases were cured, total effective rate was 100%.ConclusionManipulation can cure atlantoaxial joint malposition, relax vertebral artery, improve cerebrum blood supply, so it is available for cervical vertigo.

0.05).Among the 26 pregnancies,there occurred one ectopic pregnancy and four cases of spontaneous abortion.In the 13 delivery cases,there were one premature delivery,two cases of premature rupture of the membrane,and ten cases of cesarean section.The sample height of the cone was less than 2.0 cm in the nine delivery cases,and the mean width of the cone was over 2.5 cm.Conclusion No evidence of secondary infertility caused by cervical conization was found.There was also no significant increase in the number of either premature delivery cases or low birth weight infants. The sample height of the cone might play a more important role in the pregnancy outcome than the width, which still needs to be further verified by larger studies.

Objective To observe the therapeutic efficacy of ozone injection in treating lumbar disc herniation. Methods One hundred and four patients with CT or MRI proved lumbar disc herniation, including 144 diseased lumbar discs, were enrolled in this study. The main complains were severe pain or numbness in the low back and lower limbs. Under the X-ray guidance, a 21 G needle was punctured into the disc, followed by an injection of 4-40 ml ozone (50 ug/ml) and 40 mg prednisolone acetate into intradiscal and paravertebral space. Results All patients were followed up for 3 to 84 months with an average time of 38 months. The last follow-up check was carried out in March of 2009. The total effective rate was 77.1%, with no occurrence of any serious complications. Conclusion The percutaneous injection of medical ozone into disc and paravertebral space is an effective and safe method for the treatment of lumbar disc herniation.

Objective To observe the efficacy and adverse reaction of ozone therapy combined with gemcitabine and cisplatin (GP) regimen in patients with advanced non-small cell lung cancer.Methods Fifty-five patients with advanced non-small cell lung cancer were enrolled and allocated to treatment group (28 cases) and control group (27 cases).The patients in treatment group received ozone therapy combined with GP regimen,and the patients in control group received GP regimen only.The efficacy,quality of life,adverse reaction and cellular immune function after treatment was compared between two groups.Results There was no significant difference in the efficacy between two groups (P ＞ 0.05).The quality of life after treatment in treatment group was better than that in control group (P ＜ 0.05).The liver function damage in treatment group was lower than that in control group (P ＜ 0.05).The cellular immune function in treatment group was stronger than that in control group (P ＜ 0.05).Conclusion Ozone therapy combined with GP regimen can effectively alleviate adverse induced by GP regimen chemotherapy and significantly improve the quality of life in patients with advanced non-small cell lung cancer.

Objective To determine if the cardiac index (CI) measured with arterial pressure-based cardiac output (APCO) agrees with that measured with pulmonary artery catheter (PAC) during cesarean section in parturients with congenital heart disease and severe pulmonary hypertension.Methods Thirty parturients with congenital heart disease and severe pulmonary hypertension,scheduled for elective cesarean section,were enrolled in the study.APCO and PAC were used for cardiac output and other parameters of hemodynamics monitoring during operation in all patients.Continuous epidural anesthesia was performed.CI was recorded immediately before epidural administration (T1),at 5 and 10 min after epidural administration (T2-3),immediately before delivery (T4),and at 2 and 5 min after delivery (T5-6).The correlation was tested by Pearsone correlation analysis.CI derived from APCO and PAC was compared by Bland-Altman analysis for agreement.Results CI measured with PAC was significantly higher than that measured with APCO (P ＜ 0.05).Compared with the baseline value at T1,no significant difference in CI measured with PAC and APCO was found at T11-T4 and T6 (P ＞ 0.05),and CI measured with PAC and APCO was significantly increased at T5 (P ＜ 0.05).Bland-Ahman analysis showed poor agreement between CI measured with the two methods.The correlation analysis showed that there was positive correlation between CI derived from the two methods at T1-6 (the correlation coefficient was 0.93,0.95,0.94,0.89,0.96 and 0.91 at T1-6,respectively,P ＜ 0.05).Conclusion CI value obtained with APCO agrees poorly with that obtained with PAC during cesarean section in parturients with congenital heart disease and severe pulmonary hypertension,but agrees well in monitoring the changing trend of CI.
