Objective To investigate the value of T cell subsets predicting stroke-associated infection (SAI) in patients with acute ischemic stroke.Methods The consecutive patients with acute ischemic stroke within 36 hours after symptom onset were included.The peripheral venous blood samples were collected the next morning after admission.A flow cytometry was used to detect T cell subsets.The patients were divided into either an infected group or a non-infected group according to whether they had infection or not in hospital within 2 weeks.The information of the risk factors for ischemic stroke was collected,and the relationship between SAI and related risk factors was analyzed.Results A total of 55 patients with acute ischemic stroke were included,28 of them were in the infected group and 27 were in the non-infected group.The percentages of CD3 +T cells (63.42 ± 8.84％ vs.69.55 ± 10.05％ ; P =0.022) and CD4+ T cells (35.34 ± 7.10％ vs,40.46 ±7.24％; P =0.014),and CD4+/CD8+ ratio (1.23 ±0.38 vs.1.55 ±0.56; P =0.023) in the infected group were significantly lower than those in the non-infected group.The multiple regression analysis showed that the higher NIHSS score (odds ratio [ OR] 1.295,95％ confidence interval [ CI] 1.084 - 1.574; P =0.004) and t he decreased percent age of CD4+ T cells (OR 0.874,95 ％ CI 0.784 - 0.974,P =0.015) were the independent predicting factors for SA1.The percentage of CD4+ T cells ＜ 70.35％ had the best predictive value for the occurrence of SAI (sensitivity 77.8％ and specificity 92.3％).Conclusions The decreased proportion of the auxiliary T cells after the onset of acute ischemic stroke may increase the susceptibility of SAI.The detection of T cell subsets may predict the SAI in a certain degree.

Objective To establish the screening platform of circulating tumor cells (CTCs) using acridine orange fluo?rescent (AO-F) dyeing method, and to apply it in the screening of peripheral blood CTCs in patients with kidney cancer. Methods Twenty-seven patients with metastatic renal cell carcinoma was included in this study. Primitive tumor cells and kidney cancer cell line 769-P were cultured with different concentrations of fetal bovine serum. Smears were prepared and observed under fluorescence microscopy. The percentage of AO-F positive staining of 769-P cells under 5 random sights was calculated. The sensitivity of AO-F staining to cells was evaluated. The 5 mL morning fasting venous blood was obtained from 10 subjects with healthy check-up. The 1×106 cell suspension was prepared. The logarithmic phase of renal tumor cells was used to prepare tube containing 500, 200, 100, 50 and 10 tumor cell suspension, which were mixed with 1×106 nucleated cells to establish CTCs model of renal cancer. AO-F staining method was used to detect the expression of AO-F positive cells. The correlation between expression of AO-F positive cells and clinical parameters was analyzed. Results The prima?ry cells and cell line 769-P showed similar bright color and morphological characteristics. The percentage of AO-F positive staining in 769-P cells was 93%±3%under 5 random sights. The recovery rates (%) of four groups (500, 200, 100 and 50 tu?mor cell suspension) were 10.2±3.8, 9.2±2.3, 10.8±2.6 and 10.5±1.9, respectively. There were no significant differences in recovery rates between four groups (P>0.05). The group of 10 tumor cell suspension could find AO-F positive staining cells occasionally. Zero case was positive in controls. Nine of 27 patients were positive and the rate was 33.33%. There were no significant statistical differences in AO-F positive rates between gender, age, tumor size, pathological pattern, Furhman stage, metastasis of lung and presence of tumor (P>0.05). Conclusion It is confirmed that the method of CTCs staining with AO-F, which has high specificity and reproducibility, is feasible to detect CTCs and worthy of being studied. There is a certain reference value to predict tumor recurrence and metastasis.

This study was aimed to investigate the therapeutic effect of yin-yang meridian acupuncture by reinforc-ing-reducing with patient's respiration on lower limb function among post-stroke patients. A total of 100 stroke pa-tients were enrolled and randomly divided into two groups, which were the control group and the treatment group, with 50 cases in each group. Basic treatment was given in the control group with no related rehabilitation treatment. Basic treatment was given in the treatment group combined with yin-yang meridian acupuncture by reinforcing-re-ducing with patient's respiration. All patients were assessed with kinematics time parameters at the beginning of the treatment and 28 days after the treatment on muscle strength, muscular tension and the change of joint movement of hip joint and knee joint among patients. The results showed that compared with the control group, there was significant difference in treatment group on muscle strength, muscular tension and the change of joint movement of the hip joint and knee joint 28 days after the treatment (P < 0.01). It was concluded that yin-yang meridian acupuncture by reinforcing-reducing with patient's respiration can effectively increase the muscle strength, reduce muscular tension, and improve the change of joint movement, in order to increase the lower limb movement func-tion among stroke patients.

Objective: To observe the effect of reinforcing and reducing manipulation by breathing on yin and yang meridian points for motor function of knee joints in patients with ischemic stroke. ＜br> Methods: A total of 60 ischemic stroke cases were randomly allocated into an observation group and a control group, 30 in each group. Other than basic and conventional rehabilitation therapies, cases in the observation group were treated with reinforcing and reducing manipulation on yin and yang meridians points for a period of 8 weeks; whereas cases in the control group only received the same basic and conventional rehabilitation therapy as that in the observation group. Then the knee joint energy, support moment and shaking moment were compared between the two groups before treatment, and after 4-week and 8-week treatment respectively. ＜br> Results: Before treatment, there were no between-group significant differences in knee joint energy, support moment and shaking moment (all P>0.05). After treatment, the knee joint energy, support moment and shaking moment in both groups were significantly improved (P＜0.05). After 8 weeks of treatment, the knee joint energy, support moment and shaking moment in both groups were significantly improved than that of 4-week treatment (P＜0.05). In addition, there were between-group statistical significances in comparing knee joint energy, support moment and shaking moment after 4 and 8 weeks of treatment (P＜0.05). ＜br> Conclusion: Reinforcing and reducing manipulation by breathing on yin and yang meridian points can increase the knee joint support and shaking force and moment in stroke patients and improve their walking ability.

Objective To observe the change of extension-flexion arc of ankle in hemiplegia due to ischemic stroke after yin-yang acupuncture associated with respiration needling manipulations.Method Sixty ischemic stroke patients were divided into a control group and a treatment group by random number table, 30 in each group. The control group was intervened by basic treatment, while the treatment group was by yin-yang acupuncture associated with respiration needling manipulations in addition to the basic treatment. Before intervention and 28 d after intervention, the Lokomat gait analysis system was adopted to observe the change of the extension-flexion arc of ankle respectively under motorial and stationary states.Result When heel was grounded, the flexion angle, the maximum extension-flexion arc value, and motility of ankle joint of the treatment group were statistically different from those of the control group (P＜0.05).Conclusion Yin-yang acupuncture associated with respiration needling manipulations can effectively improve the movement and the walk function of hemiplegia due to ischemic stroke.

Objective To observe the effect of yin-yang acupuncture in association with respiratory reducing-reinforcing needling manipulations on the gait cycle in patients with post-stroke hemiplegia. Methods Sixty patients with ischemic stroke were randomized into a treatment group and a control group, 30 each. The control group was intervened by conventional medication, while based on which the treatment group was additionally given yin-yang acupuncture in association with respiratory reducing-reinforcing needling manipulations. The kinematic time parameters were evaluated before intervention and after 28-day treatment. Results After intervention, the stance phase of the affected side and the healthy side, ambulation cycle, swinging phase of the affected side and the healthy side, and the stance phase of both limbs in the treatment group were significantly different from that in the control group(P＜0.05). Conclusion Yin-yang acupuncture in association with respiration reducing-reinforcing needling manipulations can effectively improve the gait cycle and ambulation function of the patients with post-stroke hemiplegia.

Objective To investigate the correlation between ADC value and glioma IDH-1/1p19q genotype. Methods The MRI features and molecular pathological results of 69 patients with pathologically confirmed diagnosis of WHO grade Ⅱ/Ⅲ glioma between March 2013 and December 2020 were retrospectively analyzed. The diagnostic performance of ADC values on glioma genotypes (IDH-1, 1p19q) was evaluated using the ROC curve of the subjects' working characteristics. Results The ADCmean, ADC_min, rADC_mean, and rADC_min in the IDH-1 mutation group were significantly higher than those in the IDH-1 wild group (P < 0.05, P < 0.01, P < 0.05, P < 0.01). The use of the rADC_min threshold (0.979×10³mm²/s) had the highest efficacy (AUC=0.770) for diagnosis of IDH-1 mutant and IDH-1 wild-type gliomas as well as sensitivity and specificity of 84.61% and 59.09%, respectively. Conclusion ADC can be used as an imaging biomarker for noninvasive prediction of IDH-1 mutant and wild-type Ⅱ /Ⅲ gliomas.

To establish a high performance liquid chromatography (HPLC) method for simultaneous determination of four alkaloids(arecoline， guvacoline， arecaidine， and guvacine) in Arecae Pericarpium (AP) and Arecae Semen (AS), and compare the contents of these four alkaloids between different medicinal parts. The chromatographic conditions were as follows:Welch SCX（4.6 mm×250 mm， 5 μm）column, with acetonitrile-0.2% phosphoric acid solution (adjusted to pH 3.85-3.90 with ammonium hydroxide) at 50:50 as the mobile phase, at a flow rate of 0.5 mL·min⁻¹. The column temperature was set at 35 °C, and the detection wavelength was 215 nm. The results of content determination in 7 batches of AS and 10 batches of AP showed that, the contents of 4 alkaloids in AS (arecaidine 0.020%-0.045%, guvacine 0.031%-0.086%, arecoline 0.194%-0.346%, and guvacoline 0.065%-0.094%) were generally higher than those in AP (arecaidine 0.10%-0.032%, guvacine 0.006%-0.029% arecoline 0.00%-0.070%, and guvacoline 0.00%-0.020%), and most of the APs had no arecoline and arecaidine at all in fruit peel. The above results indicated that different alkaloids can be used to distinguish the different medicinal parts of Arera catechu. Arecoline， guvacoline， arecaidine， and guvacine can be used as the quality control markers of AS, while for AP, only arecaidine and guvacine were needed.
