Objective: To explore the effects of acupuncture combined with Brunnstrom staging on upper-limb motor function, cerebral arterial blood flow velocity, and brain function remodeling after stroke. Methods: A total of 77 patients after stroke were selected between January 2017 and December 2019 to perform a prospective study. All cases were divided into an observation group and a control group by the random number table method. Both groups were treated with conventional symptomatic treatment for stroke and functional exercise according to the Brunnstrom staging. The observation group was treated with additional acupuncture treatment based on the Brunnstrom staging therapy. The therapeutic efficacy was evaluated after six-week treatment. The traditional Chinese medicine (TCM) symptom scores of dizziness, headache, limb numbness, and language disorders before and after the treatment in the two groups were compared. According to the Fugl-Meyer motor function assessment (FMA), the upper-limb motor function before and after the treatment was compared. And the average systolic blood flow velocity of the anterior cerebral artery (ACA), middle cerebral artery (MCA), and posterior cerebral artery (PCA) in the two groups before and after the treatment were compared. According to the modified Edinburgh-Scandinavia stroke scale (MESSS), the nerve function before and after the treatment was compared. Results: The total effective rate of the observation group was 94.9％, significantly higher than 79.0％ of the control group (P<0.05). After the treatment, the TCM symptom scores of dizziness, headache, limb numbness, and language disorders in both groups decreased, and the scores in the observation group were all significantly lower than those in the control group (P<0.05). The FMA score of upper limbs in both groups increased, and the score in the observation group was significantly higher than that in the control group (P<0.05). The average systolic blood flow velocities of the ACA, MCA and PCA in both groups increased, and were significantly higher in the observation group than in the control group (P<0.05). The MESSS score in both groups decreased, and the score in the observation group was significantly lower than that in the control group (P<0.05). Conclusion: Acupuncture combined with Brunnstrom staging is effective for patients after stroke. It can effectively improve the upper-limb motor function and cerebral artery blood flow velocity, promote brain function remodeling, and restore nerve function.

Objective To investigate association of IL-10 gene promoter polymorphisms with first episode schizophrenic and efficacy of risperidone.Methods 513 schizophrenic patients with first episode(patient group) and 627 health controls(control group)participated in this study.Genotyping for IL-10 gene label single nucleotide polymorphism(SNP) sites-592A/C (rs1800872),-1082A/G (rs1800896),-819T/C (rs1800871) were performed by polymerase chain reaction and restriction fragment length polymorphism (PCR-RFLP)genotyping technology.513 patients were administered orally risperidone for 8 weeks.Clinical efficacy were evaluated with PANSS.Results The frequences of rs1800896 genotypes (332:166:15,453:161:13 ; x2 =7.55,df=2,P=0.02) and alleles(830:196,1067:187; x2 =7.09,df=1,P=0.008,OR=1.35,95％ CI=1.08 ～ 1.68) showed significant differences between patient group and control group,however only allele differences showed statistical significance after Bonferroni correction (P=0.024).The frequencies of rs1800872and rs1800871 genotypes and alleles had no significant differences between patient group and control group(P＞0.05).There were no significant differences of haplotype frequences between patient group and control group (P＞ 0.05).There were no significant differences of genotypes (134:209:38,61:59:12;x2 =5.16,df=2,P=0.08;244:129:8,88:37:7;x2 =4.57,df=2,P=0.10; 188:158:35,54:64:14;x2=2.80,df=2,P=0.25) and alleles (477:285,181:83;x2 =3.03,df=1,P=0.08;617:145,213:51 ;x2 =0.01,df=1,P=0.92;534:228,172:92;x2 =2.22,df=1,P=0.14) frequences of rs1800872,rs1800896,rs 1800871 between effective group (381 cases) and invalid group (132 cases) of Risperidone efficacy (P＞ 0.05),while ATC haplotype frequences had significant difference between two groups(x2 =7.501,P=0.006,OR (95％ CI) =2.420(1.262-4.640)).Conclusion IL-10 gene rs1800896 polymorphism may be associated with susceptibility to schizophrenia.The clinical curative effect of risperidone in the treatment of schizophrenia is associated with ATC haplotype,ATC haplotype may be good predictors to the overall curative effect of risperidone.

Renal cell carcinoma(RCC)is currently one of treatment-resistant malignancies and is not sensitive to conventional radiotherapy or chemotherapy.The effective rate of high dose of recombinant human interleukin-2(IL-2)and recombinant human interferon-α(IFN-α)was only 10%-15%.Advances in the understanding of cancer at molecular level have led to more progress in the development of anti-cancer agents.Recently,mutation of Von Hippel-Lindau(VHL),Ras,PTEN genes have been observed in RCC and the mutation can result in different expression levels of RTK.Among the newly invented medications for targeted cancer therapy,protein kinase inhibitors target intracellular molecules crucial in sighaling pathways of cancer cell survival and proliferation.Compared with conventional chemotherapy and immune therapy,targeted therapy is effective,with fewer adverse effects.According to 2009 NCCN Clinical Practice Guidelines in oncology,this article reviewed the clinical application of sunitinib,sorafenib,temsirolimus,and bevacizumab in the targeted therapy for renal cell carcinoma.
