Visfatin was recently reported as an adipokine and was found to exert insulin-mimicking effects.The results showed that the expression of visfatin parallelled with obesity and insulin resistance in long term high fat chow-fed rats.The expression of visfatin mRNA was decreased and the insulin resistance improved after rennin-angiotensin system was blocked.Visfatin may play an important role in the pathogenesis of insulin resistance.

Objective:To investigate the induction effect of NPPB,a chloride channel blocker,on the apoptosis of human glioma SHG-44 cells,and to explore its mechanism. Methods:The SHG-44 cells were cultured in vitro and divided into control group and NPPB groups (50,100,200 μmol· L-1 ).The cell viability was detected by MTT assay.The apoptotic rates were detected by flow cytometry.The expression levels of Bax, Bcl-2 and caspase-3 were detected by immunohistochemical analysis and Western blotting method.Results:Compared with control group,the cell viabilities of SHG-44 cells in 100 and 200 μmol·L-1 NPPB groups after treated for 24 and 48 h were decreased significantly (P < 0.01).The results of flow cytometry showed that the apoptotic rates of SHG-44 cells in 100 and 200 μmol·L-1 NPPB groups were 24.64% and 41.85%,and they were higher than that in control group (4.17%) (P <0. 01).The immunohistochemical analysis and Western blotting results showed that the expression levels of caspase-3 and Bax proteins in SHG-44 cells in 100 μmol · L-1 NPPB group were increased (P < 0.05 or P < 0. 01 ), and the expression level of Bcl-2 protein was decreased (P < 0.05 ). Conclusion:NPPB could induce the apoptosis of human glioma SHG-44 cells by the down-regulation of the expression of Bcl-2 and the up-regulation of the expression of Bax,and the activation of caspase-3.

Objective: To compare blood levels of NT-proBNP and uric acid (UA) in patients with pulmonary thromboembolism (PTE) and chronic heart failure (CHF). Methods: A prospective research was conducted in 288 acute dyspnea patients treated in our hospital from 2010-06 to 2015-05. The patients were divided into 2 groups based on clinical diagnosis: PTE group,n=107 and CHF group, n=181. Blood levels of NT-proBNP and UA were examined in all patients, statistical analysis was performed by SPSS 17.0 software, independent samplet test or variance analysis were used to make comparison between 2 groups. Results: There were more male patients as 64/107 (59.8%) in PTE group and 103/181 (56.9%) in CHF group. Compared with CHF group, PTE group had the lower blood levels of NT-proBNP (2421.7±1678.1) pg/ml vs (6964.3±3873.1) pg/ml and UA (340.6±121.3) μmol/L vs (492.1±166.2) μmol/L, allP<0.01. Conclusion: In our research, blood levels of NT-proBNP and UA were lower in PTE patients than CHF patients; with general background, such phenomenon might be helpful to distinguish PTE and CHF in acute dyspnea patients in clinical practice.

Objective:To explore the clinical features and prognosis of patients with primary central nervous system lymphoma(PCNSL).Methods:A retrospective analysis was performed on the relationship between clinical features,treatment regimen and prognosis in 46 newly diagnosed patients with primary central nervous system lymphoma who were diagnosed and treated in The Second Hospital of Lanzhou University from January 2015 to September 2022.Fisher's exact probability method was used to analyze the differences in clinical data of different subgroups.Kaplan-Meier survival curve was used to analyze the overall survival rate and progression-free survival rate of patients with different treatments,and the factors influencing survival were analyzed.Results:Among 46 patients with PCNSL,which pathological type were diffuse large B-cell lymphoma(DLBCL).There were 26(56.5％)cases of male and 20(43.5％)of female,with a median age of 54(17-71)years.In Hans subtypes,14 cases(30.4％)of GCB subtype,32 cases(69.6％)of non-GCB subtype.32 cases(69.6％)of Ki-67 ≥80％.Among 36 patients who completed at least 2 cycles of treatment with follow-up data,the efficacy evaluation was as follows:overall response rate(ORR)was 63.9％,complete response(CR)rate was 47.2％,17 cases of CR,6 cases of PR.The 1-year progression-free survival rate and 1-year overall survival rate was 73.6％and 84.9％,respectively.The 2-year progression-free survival rate and 2-year overall survival rate was 52.2％and 68.9％,respectively.The ORR and CR rate of 17 patients treated with RMT regimen was 76.5％and 52.9％(9 cases CR and 4 cases PR),respectively.Univariate analysis of 3 groups of patients treated with RMT regimen,RM-BTKi regimen,and RM-TT regimen as first-line treament showed that deep brain infiltration was associated with adverse PFS(P=0.032),and treatment regimen was associated with adverse OS in PCNSL patients(P=0.025).Conclusion:Different treatment modalities were independent prognosis predictors for OS,the deep brain infiltration of PCNSL is a poor predictive factor for PFS.Patients with relapse/refractory(R/R)PCNSL have a longer overall survival time because to the novel medication BTKi.They have strong toleration and therapeutic potential as a first-line therapy for high-risk patients.

In recent years, more and more attention was payed to the study of andrographolide. Andrographolide has the extensive pharmacological actions, such as anti-tumor, dephlogisticate and antibiosis and anti-virus. It was dected that andrographolide had the action of anti-tumor in gastric cancer, liver cancer, lung cancer and breast cancer. The anti-tumor mechanism of andrographolide was versatile, for instance, andrographolide can induce the apoptosis of cancer cell, inhibit the cell cycle, and increase the antitumor activity of lymphocyte. The following review was about the recent progress of study on the anti-tumor mechanism of andrographolide.

Photosynthetic and growth characteristics of Angelica dahurica were studied in order to clarity the relations of photosynthesis, growth and root dry weight, and provide a theoretical basis for its cultivation. Photosynthesis and growth indexes were meas- ured every 25 days. The contents of chlorophyll a, b, a + b, soluble protein and the activities of Hill reaction, Ca(2+)-ATPase, Mg(2+)-ATPase had an increasing trend; They had the highest value in leaf high-speed growth period. Then, they were decreased in root high- speed growth period. The root dry weight showed negative corelation with photosynthetic characteristics indexes except stomatal con- ductance, however, the negative corelation only from net photosynthetic rate and Ca(2+)-ATPase were significant. The vegetative growth period of spring sowing A. dahuricia was divided into three phases: seedling period, leaf high-speed growth period and root high-speed growth period. The root dry weight showed a significantly positive corelation with the root diameter, leaf dry weight, shoot dry weight, aboveground dry weight. There was the competitive relation between aboveground and underground, so underground growth could be es- timated from leaf area and shoot dimeter.

Acute cerebral infarction(ACI)has the characteristics of onset nasty and high mortality,and thus the rapid determination of the occurrence and development of ACI plays a key role in the diagnosis,treatment and prognosis of ACI patients.It has shown that the serum level of human haptoglobin(Hp)is related to ACI.In this study,surface enhanced Raman scattering(SERS)combined with immune recognition was applied to establish a quantitative analysis method for serum Hp.Firstly,the SERS substrate of silver nanoparticles was prepared on silicon wafer,and 4-mercaptobenzoic Acid(MBA)was used as a Raman probe by forming Ag—S bond and connecting it on the surface of nanoparticles.The carboxyl group of MBA was linked to amino group of self-made high-affinity antibody through forming CO—NH structure thus forming a SERS self-assembled chip of Hp(Ag/MBA/anti-Hp).Hp in serum could be specifically captured by antibodies on SERS substrate,which caused the shift of SERS characteristic peak of MBA.The results showed that there was a good linear relationship between the logarithm of Hp concentration and the SERS characteristic peak shift of MBA.The detection range was 1-1000 ng/mL(R2=0.988).The Hp concentrations in serum of 90 ACI patients were determined by this method,and the results were consistent with those of ELISA method,which proved the practicability and accuracy of this method.This method was highly specific,simple and convenient,which could realize the specific recognition and quantitative analysis of serum Hp,so as to be an effective means for clinical detection of serum Hp,thus providing a reference for the treatment and prognosis of ACI.

OBJECTIVETo observe the impact on lower limbs balance function in treatment of yin-yang meridians acupuncture with respiratory reinforcing and reducing manipulation involved in the patients of stroke by applying B-PHY balance function test training system so as to provide the objective evidence in treatment of stroke; with acupuncture.

METHODSOne hundred patients were randomized into an observation group and a control group, 50 cases in each one. In the control group, the basic treatment was applied, without other relevant rehabilitation therapies associated. In the observation group, with the basic treatment as the control group's, the therapy of the yin-yang meridians acupuncutre with respiratory reinforcing and reducing manipulation was adopted. On the yin meridians, Zuwuli (LR 10), Xuehai (SP 10), Yinlingquan (SP 9), Sanyinjiao (SP 6) and the others were selected and stimulated with reducing manipulation achieved by the coordination of patient's respiration. On the yang meridians, Biguan (ST 31), Liangqiu (ST 34), Yanglingquan (GB 34) and the others were selected and stimulated with reinforcing manipulation achieved by the coordination of patient's respiration. The treatment was given once a day and for 28 days totally. Before treatment and in 28 days of treatment, B-PHY balance function test training system was used to determine the weight shift track parameters (track length, peripheral square, track length of per unit square, left-right offset and rectangle square), the weight shift track distance parameters [mean of X axle weight shift distance (Mean-X), mean of Y axle weight shift distance (Mean-Y), maximum of X axle weight shift distance (Max-X), maximum of Y axle weight shift distance (Max-Y), weight shift distance (LSKG), weight shift square (SSKG), square ratio of weight shift (LFS)], stability coefficient (SI) and weight distribution coefficient (WDI).

RESULTSAfter treatment, the differences in the weight shift track parameters, SI and WDI were significant as compared with those before treatment in the patients of the two groups (all P<0.01); while the differences in the weight shift distance parameters in the observation group were improved obviously after treatment as compared with those before treatment (all P<0.01), the differences of Mean-X, Max-Y and LFS in the control group were improved after treatment as compared with those before treatment (all P<0.01). Except SSKG, the improvements after treatment in the rest indices in the observation group were better than those in the control group (all P<0.05).

CONCLUSIONThe yin-yang meridians acupuncture with respiratry reinforcing and re- ducing manipulation effectively improves the lower limbs balance function in the patients of stroke.
