Objective To observe the effect of cluster needling at scalp acupoints plus paraffin therapy on motor function in cerebral palsy patients.Method Forty eligible patients with spastic cerebral palsy were randomized into a control group and an experimental group, 20 cases in each group. The control group was intervened by cluster needling with long-time retaining of the needles plus Uyeda's approach and conventional rehabilitation trainings specifically for spastic cerebral palsy; the experimental group was intervened by paraffin therapy in addition to the treatment given to the control group. The interventions were conducted once a day, for a total of 8 weeks. The Gross Motor Function Measure-88 (GMFM-88) and Modified Ashworth Scale (MAS) were adopted to evaluate the motor function before and after the treatment.Result The GMFM-88 scores were significantly changed after the treatment in both groups (P<0.05), and there was a significant difference in comparing the GMFM-88 score between the two groups after the intervention (P<0.05). The MAS score was significantly changed after the intervention in the experimental group (P<0.05), while the score wasn't significantly changed in the control group (P>0.05); there was a significant difference in comparing the MAS score between the two groups after the intervention (P<0.05).Conclusion On the basis of conventional rehabilitation trainings, cluster needling at scalp acupoints plus paraffin therapy can produce a significant efficacy in improving the muscular tension and motor function, and benefit the development of cerebral palsy patients.

Objective To observe the effect of Professor Deng Tietao’s Brain-strengthening Recipe 1 on learning and memory abilities of rats with vascular dementia, and to explore its molecular biology mechanism. Methods The vascular dementia rat model was established by permanent occlusion of the bilateral arteria carotis communis. Sixty male SD rats were randomly divided into 5 groups, namely sham-operation group, model group, nimodipine (5.4 mg·kg-1·d-1) group, and high-and low-dose Chinese medicine groups (57.6 and 14.4 g·kg-1·d-1, respecitvely) . After medication for 30 days, the learning and memory abilities were evaluated by Morris water maze test. The histological changes of the rat hippocampal tissues were observed after HE staining, and the mRNA expression of N-methyl-D-aspartate receptor subunit 2B ( NR2B) in rat hippocampus was measured by real-time fluorescence quantitative polymerase chain reaction (RT-PCR) . Results The water maze test results showed that the escape latency of the rats in the sham-operation group was significantly decreased on the third day, and was significantly decreased in the high-dose Chinese medicine group on the fourth day ( P<0.05 compared with the model group). The results of spatial probe test showed that the times of rats passing through the platform within 60 seconds were significantly higher in high-dose Chinese medicine group ( P<0.01compared with the model group) , but the time for rat staying at the quadrant of the platform in the other four groups did not differ from that in the model group ( P>0.05). HE staining results for the model group were presented as the absence of neural cells in hippocampus CA1 region, karyorrhexis of nerve cells, indistinctness of nuclear membrane, disappearance of nucleolus, shrinkage of nerve cells, increase of cytoplasm acidophily, and reactive hyperplasia of astrocytes. And in the hippocampal CA1 region of high- and low-dose Chinese medicine groups, the injured neural cells were found, and the lesions were slighter than those of the model group. Compared with the model group, the mRNA expression of NR2B was increased in nimodipine group and high-dose Chinese medicine group ( P<0.05) . The mRNA expression of NR2B showed a increasing trend in low-dose Chinese medicine group, but the differences were insignificant compared with that of the model group ( P>0.05). Conclusion Brain-strengthening Recipe 1 has obvious effects on improving the learning and memory abilities of vascular dementia rats, and the therapeutic mechanism is associated with reduction of the degree of neuronal damage in hippocampus and with the upregulation of the mRNA expression of NR2B.

Objective: To evaluate the efficacy and safety of the combination therapy of Compound Danshen Dropping Pills and conventional chemical drugs in the treatment of the angina by Meta-analysis. Methods: Databases including CNKI, WanFang, CBM, VIP, PubMed, and Cochrane Library were searched to collect qualified researches, and the quality of articles was evaluated according to Cochrane Handbook. Meta-analysis including subgroup analysis was performed by using Stata 13.1 and RevMan 5.3 software. All these methods were used to systematically evaluate the safety and clinical efficacy of Compound Danshen Dropping Pills in the treatment of angina pectoris under two circumstances (with or without syndrome differentiation). Results: A total of 39 studies involving 3 941 patients were studied, including 1 991 patients in the experimental group and 1 950 in the control group. The results of Meta analysis showed that: the clinical efficacy [RR = 1.24, 95%CI (1.20, 1.28), P < 0.000 01], ECG efficacy [RR = 1.29, 95%CI (1.21, 1.37), P < 0.000 01], angina attack frequency [WMD = -1.82, 95%CI (-3.28, -0.36), P = 0.01], duration of angina attack [WMD = -2.09, 95%CI (-2.67, -1.50), P < 0.000 01], hs-CRP [WMD = -2.63, 95%CI (-4.39, -0.86), P = 0.003], ET [WMD = -16.22, 95%CI (-19.37, -13.06), P < 0.000 01], platelet aggregation [WMD=-7.46, 95%CI (-11.15, -3.78), P < 0.000 1], GMP-140 [WMD=-5.64, 95%CI (-6.88, -4.39), P < 0.000 01] and fibrinogen [WMD = -0.73, 95%CI (-1.00, -0.46), P < 0.000 01] of routine western medicine treatment combine with Compound Danshen Dripping Pills group had significant difference compared with the control group; In terms of clinical efficacy, the combination effect of dialectical medication group and non dialectical medication group had no significant difference (P = 0.55, I2 = 0). A total of 15 studies described adverse reactions, with 43 cases in the experimental group and 65 cases in the control group. There was no significant publication bias on funnel plot and Egger's test. Conclusion: It is safe and effective to use Compound Danshen Dropping Pills in patients with coronary heart disease and angina, which can further improve the clinical effect compared with the simple routine treatment. There is no significant difference between the therapeutic effect of Compound Danshen Dropping Pills and that of non-syndrome differentiation. However, these conclusions still need to be verified with more high-quality and large-sample literature.

Natural killer (NK) cells, as an essential part of innate immunity, can directly identify and kill tumor cells after being activated by the synergistic action of surface inhibitory receptors and activated receptors. It can secrete cytokines to recruit dendritic cells (DCs), induce DCs maturation and enhance adaptive immune response. It can target cancer stem cells (CSCs) and circulating tumor cells (CTCs) to inhibit cancer metastasis. NK cells have a unique inflammatory tendency, which can respond to cytokines and chemokines released from tumor sites and migrate to tumor sites, making them occupy an important advantage in cancer targeted therapy. The research on cancer targeted therapy of NK cells as drug delivery carriers, NK cell membrane-coated biomimetic nanoparticles, and NK cell extracellular vesicles (NKEVs) has attracted more and more attention. The article will focus on the mechanism of NK cells inhibiting cancer, and summarize the research progress of cancer targeted therapy of NK cells.

Signal transducer and activator of transcription 3 (STAT3) is an important regulatory factor of cell proliferation and metastasis, involved in the occurrence and development of a variety of malignant tumors, and it is one of the hot spots in the research of targeted anti-tumor drugs. Our group screened a novel benzobis (imidazole) structure small molecule compound LZJ541 through the screening model of Janus kinase (JAK)/STAT3 pathway inhibitors, which has definite STAT3 inhibitory activity. We examined the effect of LZJ541 on the proliferation of HepG2 and PC-3 cells by MTT assay in vitro, detected the effect of LZJ541 on the expression of STAT3-related proteins in HepG2 cells by Western blot, and measured the effect of LZJ541 on the apoptosis and cell cycle arrest of HepG2 cells via flow cytometry. The results indicated that LZJ541 significantly inhibited the activation of STAT3 signaling pathway and restrained the proliferation of HepG2 cells. Its half maximal inhibitory concentration (IC₅₀) was 13.8 μmol·L^-1, which was much lower than that of PC-3 cells (with low STAT3 expression, IC₅₀: 41.99 μmol·L^-1), LZJ541 can also inhibit the phosphorylation of STAT3 in HepG2 cells, thereby inducing apoptosis and cycle arrest and then exerting anti-tumor effects. In conclusion, LZJ541 has a certain anti-tumor effect in vitro, which provides an experimental basis for the development of new STAT3-targeted anti-tumor drugs around this kind of compounds.

Objective To study the protein expression of Tspan-1 gene in colorectal carcinoma,and investigate the relationship between the expression and biologic behavior of colorectal carcinoma. Methods Immunohistochemical ELIVISION two-step method was used to detect the protein expression of Tspan-1 gene in 80 cases of colorectal carcinoma,13 cases of colorectal adenoma and 27 cases of normal colorectal tissues. Results The positive expression rate of Tspan-1 in colorectal carcinoma was significantly higher than that in colorectal adenoma and normal colorectal tissues,there was significant difference in the expression among the three groups.The positive expression rate of Tspan-1 was 90% in colorectal carcinoma,23% in colorectal adenoma and 7% in normal colorectal tissues (P ＜ 0.01).The positive expression rate of Tspan-1 in poor and moderately differentiated carcinoma was significantly higher than that in well-differentiated carcinoma (P ＜ 0.01).The expression of Tspan-1 was significantly associated with lymph node metastasis (P＜0.01),and with the 5-year survival rate of colorectal carcinoma patients,with also TNM stage and the depth of tumor invasion (P ＜0.01),and while it was not associated with gender,age,location,tumor size,and type (P ＞ 0.05). Conclusion The expression of Tspan-1 gene could be as a marker predicting the prodnosis of colorectal adenocarcinoma patients,also it may play an important role in the pathogenesis of colorectal adenoma.
