Lithium(Li) salt is. a kind of effective drug commonly used in the treatment and prevention of mental disorders, but its active mechanism is still not well understood. Getting on for twenty years, many research have been reported on relationship between Li salt and second messenger system, especially the effect of Li salt on adenylate cyclase. Identical result is not obtained and there are few reports on brain calmodulin (CaM) activity change by Li salt. The aim of present expcri- ment is to determine the content of CaM in raet brain by phosphodiesterase (PED) method after chronic application of Li salt and discuss preliminary the molecular mechanism of Li salt action. The result showed that marked change has happened in the content of CaM in rat brain after chronic application of Li salt. It is ins-plied that Li salt brings its action into play probably by changing the content of CaM in rat brain

Thyroglobulin antibody (TGA) production in vitro by cultured peripheral blood mononuclear cells (PBMC) from patients with autoimmune thyroid disease (AITD) was measured by ELISA technique. PBMC from patients with AITD could synthesize and secret detectable amount of TGA. The average positive rate of TGA production in vitro was 31.25%. PBMC from the patients with Hashimoto thyroiditis (HT) could produce TGA more easily than that from the patients with Graves'disease (GD). The average positive rate was 44.19% in HT and 16.22% in GD. Pokeweed mitogen could increase TGA production, but soluable thyroglobulin could not stimulate TGA synthesis and secretion. Antithyroid drug methi-mazole had some inhibition effect on TGA production in vitro. A significant positive correlation between the serum TGA and the amount of TGA produced in vitro by PBMC from HT patients (r = 0.4, P

The annual incidence of prostate cancer (PCa) continually increases. New PCa immune therapy has become the fourth line antitumor treatment following surgery, radiotherapy and chemotherapy. As the most promising research direction in cancer immunotherapy,immune checkpoint inhibitors, such as programmed cell death-1 and programmed cell death-ligand 1 (PD-1/PD-L1) inhibitors, block PD-1 and its ligand PD-L1 and then terminate the negative control signal to the T cell, thereby facilitating T cell recovery and reversal of tumor immune-escaping mechanism. These processes restore the capability of T cells for immune response and inhibit and kill tumor cells. This review summarizes the progress on the current application of PD-1/PD-L1 inhibitors in PCa clinical trials.

ObjectiveTo investigate the feasibility of apphcation of risk factors management in nursing of the fever outpatient.Methods145 patients from May to December 2009 admitted to fever clinic was defined as the control group, 157 patients from January to May 2010 admitted to fever clinic were set as the observation group. The control group was given routine nursing, while the observation group adopted risk factor management measures. The management indices of the two groups were compared.ResultsThe patients' recognition score of risk factors of fever clinic was (85.4 ± 2.7)in the observation group, higher than(73.2 ± 3.9)in the control group. Patients' satisfaction degree was 84.7％ in the observation group, higher than 67.6％ in the control group. Rate of risk event of the observation group was 1.3％, lower than 6.2％ in the control group, the incidence of nursing errors was 0.6％ in the observation group, lower than 4.1％ in the control group, rate of patients' complaints of nurses was 1.3％ in the observation group, lower than 5.5％ in the control group.ConclusionsThe implementation of risk factors management in fever clinics can reduce medical accidents, improve nursing quality, so this clinical management mode deserves promotion and application.

Objective To investigate the effect of nursing intervention on preventing leakage of urine in patients with indwelling catheter in neurology department.Methods A total of 76 patients with indwelling catheter in neurology department were randomly assigned into the observation group and the control group with 38 cases in each group.The control group received routine care,the observation group received systemic nursing intervention on the basis of routine care.The incidence of leakage of urine and patients satisfaction degree with nursing service was observed between two groups.Results The incidence of leakage of urine in the control group was 21.1％,higher than 2.6％ of the observation group.he score of satisfaction degree of the observation group was (4.66±0.62),higher than(3.26±0.42) of the control group.Conclusions Nursing intervention can effectively reduce the incidence of leakage of urine and improve the satisfaction degree of patients with indwelling catheter in neurology department,it is worthy of clinical application.

Vascular cognitive impairment (VCI) is a cognitive impairment caused by cerebrovascular disease and its risk factors,its mechanism is very complex Recent studies have shown that cerebral microbleed (CMB) is correlated with VCI.This article reviews the relationship between CMB and VCI.

Objective To study the association among the color Doppler flow pattern, vascular distribution and the lymph nodes metastasis in breast carcinomas. Methods Sixty-eight patients with infiltrating mammary gland duct carcinoma were divided into the no-lymph-nodes-metastasis group (group I , 37 cases) and the lymph-nodes-metastasis group (group Ⅱ , 31 cases), group Ⅱ were subdivided into group Ⅱa (19 cases): lateral lymph nodes positive of pectoralis minor and group Ⅱ b (12 cases): rear of pectoralis minor and subclavian lymph node positive. Blood flow parameters [peak systoltc velocity (PSV),resistent index ( RI)] and vascular Alder grades were observed and measured with color Doppler ultrasound.The results were compared with the incidence of lymph node metastasis. Results PSV and RI were not significantly different between group Ⅰ and group Ⅱ (t = -0.19,-0.63,P＞ 0.05),and also between group Ⅱ a and group Ⅱ b (t =-1.12,-013,P ＞0.05). By using vascular Alder grades,there were no significant differences between group Ⅰ and group Ⅱ (x2= 0.46, P＞ 0.05 ), but the significant differences were observed between group Ⅱ a [10.5%(2/19) ,63.2%( 12/19) ,26.3%(5/19) in Alder Ⅰ , Ⅱ , Ⅲ grade] and group Ⅱ b [8.3%( 1/12), 16.7%(2/12),75.0%(9/12)in Alder Ⅰ , Ⅱ ,Ⅲ grade](x2 = 7.41,P＜0.05). Conclusion The pattern of blood flow has no correlation with lymph nodes metastasis, vascular Alder grades of carcinoma shows some relevance with the lymph nodes metastasis in the patients with infiltrating mammary gland duct carcinoma.

Objective To investigate the identification role of plasma high sensitive Creactive protein (hs-CRP) and lipoprotein (a) (Lp [a]) levels in the diagnosis of patients with acute ischemic stroke according to the TOAST classification. Methods The levels of plasma hsCRP and Lp (a) in 82 acute stroke patients ( ＜24 hours) and 60 healthy controls were detected using immune scatter turbidimetry and immune transmission turbidity, and try to make use of Holter, ultrasonography, magnetic resonance imaging, magnetic resonance angiography/CT angiography/dagital subtraction angiography and other tests. Finally, they were classified according to the diagnostic criteria of the TOAST classification of ischemic stroke. Results There were significant differences in plasma hs-CRP and Lp (a) levels between all the subtypes of the acute ischemic sroke group and the control group (all P ＜0. 001). The the level of plasma hsCRP in patients with cardioembolism (CE) was highest. Hs-CRP could be used as a biological marker of CE subtype (odds ratio[OR] = 1. 84,95% confidence interval [CI] 1. 18-2. 85, P ＜ 0. 05). When its concentration was ＞ 3. 48 mg/L, the sensitivity and specificity of predicting CE were 89% and 83% respectively. The plasma level of the AT patients was highest, it could be used as a biological marker of AT subtype (OR = 1. 02, 95% CI 1. 01-1. 03, P＜0. 05); when its concentration was ＞ 183. 5 mg/L, the sensitivity and specificity of predicting AT were 87% and 85% respectively. Conclusions The plasma hs-CRP and Lp (a) levels of patients with acute ischemic stroke may provide some help for timely and accurate etiological typing.
