This paper presents a case of hyperthyroidism with myasthenia gravis (MG),diagnosed by neostigmine-test.Thyrotoxicosis and clinical manifestations of MG were controlled by acetylcholinesterase-inhibitor and immuno-suppressive medicine.Being followed for more than 2 years,the patient had been free of clinical symptoms of MG and his thyroid function was normal.

Objective To investigate the levels of peripheral blood CD8+ CD28- regulatory lymphocytes and their clinical values in the patients with multiple sclerosis (MS). Method From October 2005 to August 2008, 51 patients with active rehpsing-remitting MS were enrrolled from Department of Neurology of the First Affil-iated Hospital of Wenzliou Medical College. The diagnostic criteria for MS were the 2005 revisions to the "McDon-ald criteria". All the admitted patients received 1 g of methylprednisoione per day intravenously for 5 days, fol-lowed by 60 mg prednisone per day orally for 12 days,and tapered in 6 weeks. Fourteen patients were reevaluated after corticosteroid therapy. Twenty healthy individuals ,as normal controls,matched for age and sex with the MS patients were also enrolled in this study. The percentages of peripheral blood T cells (CD8+ CD28-, CD8+CD28+, CD8+, CD4+ CD8-) were measured by flow cytometric analysis. Parametric statistical analysis were per-formed using standard methods, and linear regression analysis was conducted using Pearson correlation test. Re-sults (1)Compared with controls,the patients with active MS had significantly lower percentage of CD8+ CD28-T cells [(18.48±9.89)% vs. (24.48±4.86)%, P <0.01], and higher percentage of CD8+ CD28+ T cells [(12.23±4.31) % vs. (8.55±3.49) %, P <0.01]. (2)The percentage of CD8+ CD28- T cells was negative-ly correlated with that of CD4+ CDS- T cells (r = -0.488, P < 0.01). (3) After corticosteroid therapy, the per-eentage of peripheral blood CD8+ CD28- / CD8+ CD28+ T cells didn' t significantly decrease or increase in 14 ac-tive MS patients (P > 0.05). Conclusions The decrease of peripheral blood CD8+ CD28- regulatory T cells might be associated with the pathogenesis of MS, and CD8+ CD28- regulatory T cells perhaps played their roles through CD4+ T cells. Corticosteroid therapy could not reverse the levels of CD8+ CD28- T cells.

Objective To induce experimental allergic encephalomyelitis (EAE) in female C57BL/6 mice with the extracellular domain of myelin oligedendroglia glycoprotein(MOG~(Igd)). Percentages of CD4~+ CD25~+ T cell (Tr) were tested , and also normalized expressions of Foxp3. Methods Molecular cloning technology was used to produce MOG~(Igd) fusion protein. The MOG~(Igd)-TrxA fusion protein and TrxA protein were purified by metal chelate affinity chromatography (MCAC). Mice were injected s. c. in the flank with 300 μg MOG~(Igd) in complete Frcund's adjuvant (CFA) supplemented with 4 μg/μl Mycobacterium tuberculosis. H37Rv. Mice received 0.4 ml emulsion of spinal cord homogenate of guinea pigs (GPSCH) in positive control group, and the same volume emulsiom of TrxA in negative control group, while mice served as normal control received only saline/adjuvant. Mice were monitored two times a day for continuously 30 days by double bind. Clinical scores and histopathology were evaluated. Then, mice were sacrificed. The spinal cord and brain were removed and fixed in buffered formalin. Horizontal sections taken from the central nervous system(CNS) were stained with haematoxylin and eosin (HE), and Kluver-Barrera staining. Also, immunohistochemistry was performed. Percentages of CD4~+ CD25~+ T cells were tested through flow cytometric analysis, and real-time PCR was performed to test normalized expressions of Foxp3 mRNA. Then, correlations between the two were performanced. Results Mice in both MOG group and GPSCH group shew chronic non-remitting course. The onset of disease, time when the most severe clinical symptoms happened and the clinical score between the two groups shew no significant differnces (P>0.05). However, neither in TrxA treated group nor in normal control group did animals exhibit clinical signs of EAE. Histologic sections of the brain and spinal cord taken from affected animals shew perivascular infiltration of mononuclear cells, gliosis, and multifocal demyelination. Lesions scattered throughout the CNS including brainstem, spinal cord, cerebellum, and penventricular white matter. There were significant differences between MOG group and TrxA group in the level of lesion-ceutric AQP-4 expression showing up by immunohistochemistry (P<0.05). Percentages of CD4~+ CD25~+ T cells in MOG group and GPSCH group were (4.71±1.61) % and (1.44±0.65) %, respectively, both of which were significantly lower than those in the normal control group or TrxA treated group (P<0.01). And the difference between MOG group and GPSCH group also reached statistics meaning (P<0.01). Normalized expression of Foxp3 mRNA in MOG group was 2.26± 1.97, and was not significantly higher than the 1.44±1.20 level in GPSCH group (P>0.05). However, they beth were statistically lower than that in the negative control group, namely 8.58±3.34 (P<0.01). Percentages of CD4~+ CD25~+ T cells was statistically correlated with expressions of Foxp3 mRNA (P< 0.05). Conclusion EAE induced in C57BL/6 mice with MOG~(Igd) is reproduceable. It shares the similar clinial signs and pathologic features with human multiple sclerosis(MS). Thus, we find a good way to further study the immune mechanisms of MS and also to search for the effective treatments.

OBJECTIVE:To study the protective effects of Li medicine Chushi qufeng decoction on arthritis model rats. METH-ODS:60 rats were randomly divided into normal group,model group,positive group and Chushi qufeng decoction high-dose,me-dium-dose and low-dose groups [45.9,22.95,11.48 g(crude drug)/kg]. Except for normal group,those groups were given chicken type Ⅱ collagen to induce arthritis model. After modeling,normal group and model group were given normal saline intragastrical-ly,once a day,for consecutive 12 d;Chushi qufeng decoction groups were given relevant medicine intragastrically;positive group was given leflunomide 4.5 mg/kg on 1st-3rd day and 1.8 mg/kg on 4th-12th day. The degree of joint lesion in rats were scored. The degree of joint swelling was determined as well as the serum levels of TNF-α,IL-1β and type Ⅱ collagen antibody. RESULTS:Compared with normal group,arthritis index,degree of joint swelling,the serum levels of TNF-α,IL-1βand typeⅡcollagen anti-body increased significantly in model group (P<0.01). Compared with model group,pathological score of positive group and Chushi qufeng decoction high-dose group decreased significantly,and serum levels of TNF-α,IL-1β and type Ⅱ collagen antibody decreased significantly in treatment groups(P<0.05 or P<0.01). CONCLUSIONS:Li medicine Chushi qufeng decoction has cer-tain protective effect on arthritis model rats induced by chicken typeⅡcollagen.

Objective To evaluate the influence of grape seed proanthocyanidin extract (GSPE) on sunburn cell formation and p53 protein expression induced by acute ultraviolet injury. Methods Ten volunteers were enrolled in this study. The buttock region served as the exposed region. Four areas were randomized and delineated on the buttock: one area (control area) received no exposure or product, the other 3 areas were exposed to two minimal erythema doses (MED) of simulated solar radiation (SSR) for 3 days. Of the 3 exposed areas, one area (SSR) received no product before exposure, one area (SSR + Veh) was pretreated with vehicle, the third area (SSR + GSPE) with the samples of GSPE. GSPE or vehicle was applied 30 minutes before each exposure at 2 μL/cm2. Skin biopsy was performed 24 hours after the last exposure, and skin specimens were subjected to hematoxylin eosin (HE) staining and histochemical analysis for p53 protein. Results There was a statistical difference in the number of sunburn cells per high power field (×200) between SSR sites and SSR + GSPE sites (29.8±11.1 cells vs 2.2±0.2 cells, P<0.01). A significant decrease was noticed in the account of p53 protein-positive cells per high power field (×200) in SSR + GSPE sites com-pared with the SSR sites (4.6±0.7 cells vs 19.3±3.4 cells, P<0.05). Conclusion GSPE exerts a poten-tial protective effect against acute ultraviolet injury and can serve as a natural sunscreen.

ObjectiveTo investigate the clinical effect of laparoscopic liver resection (LLR) versus open liver resection (OLR) in the treatment of patients with hepatocellular carcinoma (HCC) complicated by liver cirrhosis. MethodsA total of 136 patients who were diagnosed with HCC complicated by liver cirrhosis in Linxia Municipal People′s Hospital from January 2006 to December 2007 were enrolled and underwent LLR (LLR group, 64 patients) or OLR (OLR group, 72 patients). The short-term outcome, pathological factors, and long-term outcome were compared between the two groups. The t-test was used for comparison of continuous data between groups, the chi-square test was used for comparison of categorical data between groups, and the log-rank test was used for comparison of survival functions. ResultsThere were significant differences between the LLR group and the OLR group in time of operation ((86.43±23.55) min vs (6231±19.61) min, t=8.539, P＜0.001) and length of postoperative hospital stay ((7.22±3.45) d vs (12.27±5.31) d, t=2764, P=0.024), while there were no significant differences in intraoperative blood loss, time of hepatic portal occlusion, and overall fatality rate(all P＞005). There were also no significant differences in number of tumors, presence or absence of liver cirrhosis, microvascular invasion, resection margin, and maximum tumor diameter between the two groups (all P＞0.05). As for long-term outcome, the 1-, 3-, and 5-year disease-free survival rates were 83.30%, 48.61%, and 38.29% in the LLR group and 78.64%, 51.26%, and 4301% in the OLR group; the 1-, 3-, and 5-year overall survival rates were 97.42%, 95.13%, and 89.23% in the LLR group and 96.41%, 94.28%, and 90.06% in the OLR group. There were no significant differences in these survival rates between the two groups (all P＞005). ConclusionIn patients with HCC complicated by liver cirrhosis, LLR helps to achieve rapid postoperative recovery and similar long-term outcome compared with OLR; therefore, it holds promise for clinical application.

Objective To explore the value of transvaginal three-dimensional power Doppler ultrasound in evaluation of endometrial receptivity in patients with intrauterine adhesions.Methods Totally 43 patients with intrauterine adhesions confirmed by hysteroscopy were enrolled in this study.According to the hysteroscopy,the patients were divided into mild adhesion group (n=17),moderate adhesion group (n=18) and severe adhesion group (n=8).All the patients were examined with transvaginal three-dimensional power Doppler ultrasonography on the day of ovulation.Endometrial thickness (ED),endometrial volume (EV),endometrial vascular index (VI),endometrial flow index (FI) and endometrial vascular flow index (VFI) were compared among three groups.Results There was significant difference in EV among three groups (P＜0.001).ED,VI and VFI were significantly different between the mild and severe adhesion groups,as well as between moderate and severe adhesion groups (all P＜0.05).Conclusion Transvaginal three-dimensional power Doppler ultrasound provides a safe and noninvasive approach to assess endometrial receptivity of patients with intrauterine adhesions.EV has good predictive value on endometrial receptivity.
