OBJECTIVETo study the clinical therapeutic effect of point-through-point acupuncture on migraine and its mechanisms.

METHODSNinety cases of migraine were randomly divided into a treatment group and a control group, 45 cases in each group. The treatment group were treated with point-through-point acupuncture and the control group with normal needling method. Brain blood flow velocity was determined by TCD before and after treatment.

RESULTSThe effective rate was 97.8% in the treatment group, which was better than 80.0% in the control group (P < 0.05). And the point-through-point acupuncture could significantly improve the highest mean blood flow velocity of main arteries, with a significant difference between the two groups after treatment (P < 0.05).

CONCLUSIONPoint-through-point acupuncture can be used for treatment of migraine, with a high cured rate and obvious therapeutic effect.

Objective To evaluate the value of stereotactic core needle biopsy(SCNB)in diagnosis of breast lesions.Methods Forty-seven cases were punctured with computer-assisted stereotactic system, spring-loaded biopsy guns and 16 G core needles.The record of each item was collected,including clinical manifestations,descriptions of the mammographic characteristics(such as calcification,mass and architectural distortion),the pathology of the SCNB and the surgical pathology or mammographic follow-up data.Then the results of SCNB were analyzed based on the comparison of SCNB pathology and the surgical pathology.The reason that SCNB failed and misdioagnosed was inferred from the relationship of SCNB accuracy and the X-ray characteristics.Results Forty-four cases were punctured successfully,3 cases failed.Thirty-one patients were operated soon after biopsy.The results of 27 SCNB cases agreed well with the final pathology but the other 4 did not.Conclusions SCNB as an accurate,time-saving and cost- effective method,is also minimally invasive and hardly changes the architecture of the breast.SCNB can diagnose breast lesions in advance,reduces the number of surgical biopsy,and is promising in clinical application.

Objective To observe the expressions of bone morphogenetic protein-2(BMP-2)and bone morphogenetie protein-7(BMP-7)in the synovial tissue of fluorosis rats and its correlation with pathogenic mechanism of fluorosis arthritis.Methods Thirty-two SD rats were randomly divided into 4 groups:the control group,low,moderate and high-dose fluoride group.The control group ate commou fodder.The low,moderate and high dose fluoride group were fed with fodder composed of 25%.35%and 68%of corn(containing fluorine of 148.00 mg/kg)in chronic endemic fluorosis region in Guizhou Province.After 140 days,the expressions of BMP-2 and BMP-7 protein were determined by immunohistochemistry and assayed the absorbanee by computer image-pattern analysis system.Light microscope was used to observe the synovial tissue by Hematoxin Eosin,and calculated the pathological integral of synovium according to pathological grade standard.Results The expressions of BMP-2 (32.50±2.73)and BMP-7(38.90±2.56)in the control group was spare.Compared with the control group,the expressions of BMP-2(59.43±5.12,79.82±6.41,101.76±7.56)and BMP-7(55.10±4.82,78.42±5.61,98.46± 6.05)in the synovial tissue was up-regulated in each experimental groups(P＜0.05),especially in the moderate dose and the high-dose groups(P＜0.05).Compared with the control group(0.54±0.21).the pathological integral of synovium increased(P＜0.05)in each experimental groups(1.04±0.98,4.69±1.28,8.60±2.07).The expressions of BMP-2 and BMP-7 in the synovial tissue was found to be positively related with the pathological integral of synovium(r=0.98,0.99,P＜0.05).Conclusion The BMP-2 and BMP-7 play an important role in the development of fluorosis arthritis,probably by affecting osteogenesis.

OBJECTIVETo observe clinical therapeutic effect of head point-through-point electroacupuncture on Parkinson's disease and the mechanism.

METHODSSeventy-six cases of Parkinson's disease were randomly divided into a treatment group (n=37) treated with head point-through-point electroacupuncture and oral administration of madopa, and a control group (n=39) with only oral administration of madopa. Superoxide dismutase (SOD) and lipids peroxides (LPO) were determined before and after treatment.

RESULTSThe effective rate was 97.3% in the treatment group and 61.5% in the control group with a very significant difference between the two groups (P < 0.01). SOD activity and LPO content were significantly improved after treatment in the treatment group (P < 0.01), with a significant difference between the two groups (P < 0.01).

CONCLUSIONHead point-through-point electroacupuncture can improve SOD activity and LPO content in the body so as to cure Parkinson's disease.

Objective To evaluate the solute clearance characteristics of REXEEDTM series dialyzers during high-flux dialysis, and explore the care characteristics. Methods A randomized crossover study of 3×3 Latin square was designed based on different dialyzers. Eighteen patients with regular hemodialysis underwent dialysis with REXEEDTM-15AC dialyzer, REXEEDTM-15UC dialyzer and controlled APS-15U dialyzer, respectively. Blood samples were obtained from the blood flow entrance and exit of dialyzers, levels of urea nitrogen, creatinine, phosphate and β2-microglobulin were detected, and solute clearance rates were calculated. Before and after the third dialysis with each dialyzer, blood samples were obtained to measure the levels of urea nitrogen and creatinine, and the rates of decrease were calculated. The vital signs of each patient were intensively observed, and the venous pressure and transmembrane pressure were monitored from the dialyzers. Results The urea nitrogen clearance rates of REXEEDTM-15AC dialyzer and REXEEDTM-15UC dialyzer were significantly higher than that of APS-15U dialyzer (P<0.05). The creatinine clearance rate of REXEEDTM-15AC dialyzer was significantly higher than that of APS-15U dialyzer(P<0.05). There was no significant difference in the rate of decrease in blood urea nitrogen among different dialyzers of the same patient(>65 % for all patients). The vital signs were stable with no adverse events during dialysis, and there was no abnormal findings in laboratory security parameters. Conclusion REXEEDTM series dialyzers are effective and safe for clinical application. Great importance should be attached to the complaints from patients during dialysis. For those with less ultrafiltration, fluid as well as uhrafiltration should be supplemented to increase the transmembrane pressure.

OBJECTIVETo investigate the distribution characteristics of the single nucleotide polymorphisms (SNPs) in the promoter region of the toll-like receptor 9 gene (TLR9) in Chinese Han children from Zhejiang province, and their associations with asthma susceptibility and phenotypes.

METHODSA case-control study was conducted. A total of 312 asthmatic children aged between 1.9 and 11.6 and 339 age matched healthy controls were enrolled in this study from April 2007 to November 2008. The -1486 C/T in rs187084 and -1237 C/T in rs5743836 loci of the TLR9 gene were genotyped by direct DNA sequencing of the PCR products. Serum levels of IFN gamma, IL-12 and IL-4 were detected by enzyme linked immunosorbent assay.Serum levels of total IgE were detected by chemiluminescence, and serum levels of antigen specific IgE antibodies were detected by fluoroenzymeimmunoassay.

RESULTS(1) The -1486 C/T polymorphism was identified in both groups. The genotype frequencies of TT, TC and CC at -1486 C/T were 41.0%, 44.3%, 14.7% in the healthy controls, and 38.8%, 48.4%, 12.8% in the asthmatic children. The -1237 C/T polymorphism was not detected in the population. (2) There were no statistically significant differences in the allele and genotype frequencies at the -1486 C/T locus between the two groups (P;>0.05). (3) Serum levels of IFN gamma and IL-4 differed significantly among the three genotypes at the -1486 C/T locus in asthmatic children (P<0.01). The CC genotype had the lowest levels of serum IFN gamma and the highest levels of serum IL-4 among the three genotypes. There were no significant differences in these cytokines among the healthy controls (P>0.05). No statistical differences of serum IL-12 were found among the three genotypes in the two groups (P>0.05). (4) There were no significant differences of total IgE (log-transformed) among the three genotypes in the asthmatic children (P>0.05).

CONCLUSIONThe -1237 C/T polymorphism of TLR9 gene was not detected in Chinese Han children in this study. The -1486 C/T polymorphism was associated with the levels of serum IFN gamma and IL-4 in children with asthma. However, there were no correlations between the -1486C/T polymorphism and serum IL-12 levels, total IgE levels or asthmatic susceptibility.

Objective:To investigate the effect of Relative Bedrest Condition Morita Therapy(RBCMT) on the improvement of depression and anxiety symptoms and personality in patients with recurrent depression disorder.Methods:Seventy patients with recurrent depressive disorder hospitalized in Kailuan Mental Health Center were randomly divided into study group and control group( n=35 in each group) from June to October, 2019.The study group was given RBCMT on the basis of conventional treatment and nursing.The Eysenck personality questionnaire (EPQ), Hamilton depression scale (HAMD) and Hamilton anxiety scale (HAMA) were used to assess the clinical symptoms and personality characteristics of the patients and to analyze and compare them. Results:(1) EPQ score in each dimension: There were significant differences within group among different time in introverted and extroverted dimension (study group: baseline: 46.14±10.99, the fifth weekend: 50.43±8.86, the eighth weekend: 53.86±7.08, F=6.291, P=0.003.Control group: baseline: 45.29±8.99, the fifth weekend: 48.29±8.31, the eighth weekend: 50.29±7.57, F=3.211, P=0.044) and neuroticism dimension score (study group: baseline: 60.14±5.49, the fifth weekend: 53.29±4.53, the eighth weekend: 50.57±4.33, F=36.809, P<0.001.Control group: baseline: 60.29±6.18, the fifth weekend: 55.86±6.00, the eighth weekend: 53.14±5.30, F=13.353, P<0.001) among different time points in the group.Neuroticism scores between the two groups at the same time were statistically significant(the fifth weekend: F=4.095, P=0.047, the eighth weekend: F=4.940, P=0.030). After 8 weeks of inclusion, there was a statistically significant difference between the two groups in the score of introverted and extroverted dimension ( F=4.157, P=0.045). There was no significant difference in the score of spiritual quality dimension at different time within the group or at the same time point between the groups.(2)HAMD score: There were statistically significant differences within group among different time(study group: baseline: 32.00±4.04, the fifth weekend: 15.23±5.01, the eighth weekend: 9.31±3.15, F=282.376, P<0.001.Control group: baseline: 31.91±4.59, the fifth weekend: 17.86±5.11, the eighth weekend: 11.17±3.64, F=195.019, P<0.001), and the differences between the two groups at the same time were statistically significant (the fifth weekend: F=4.724, P=0.033, the eighth weekend: F=5.205, P=0.026). (3)HAMA score: There were statistically significant differences within group among different time(study group: baseline: 18.69±8.87, the fifth weekend: 10.34±5.34, the eighth weekend: 7.97±2.98, F=28.679, P<0.001.Control group: baseline: 18.60±8.02, the fifth weekend: 13.31±6.35, the eighth weekend: 10.37±4.86, F=14.241, P<0.001). The difference between the two groups at the same time point was statistically significant (the fifth weekend: F=4.161, P=0.045, the eighth weekend: F=8.315, P=005). (4)Multiple linear regression results indicated that RBCMT ( β=-0.312, t=-2.360, P=0.022) and introverted and extroverted dimension personality ( β=-0.334, t=-2.355, P=0.022) were the influencing factors of HAMA. Conclusion:Compared with the conventional treatment, the Relative Bedrest Condition Morita Therapy can reduce the anxiety symptoms and improve the depressive symptoms by enhancing the extraversion personality characteristics of the patients.

Objective: To investigate the relation between nicotinic acetylcholine receptor subunit (nAChR) genes and schizophrenia, and the relation between tag single nucleotide polymorphism (rs1317286, rs1044396, rs6494212, rs16969968, and rs684513) and schizophrenia in Han Chinese people. Methods: The protein-protein interaction (PPI) network among nAChR protein and 350 proteins encoded by schizophrenia-related susceptibility genes was constructed through the String database to explore whether nAChR genes were associated with schizophrenia in these known databases. Then, five single nucleotide polymorphisms (SNPs) of CHRNA3 (rs1317286), CHRNA4 (rs1044396), CHRNA7 (rs6494212), and CHRNA5 (rs16969968, rs684513) were analyzed in a sample of 1,035 schizophrenic patients and 816 healthy controls. The interaction between the markers was analyzed using multifactor dimensionality reduction (MDR) software. Power analysis was performed using the Quanto program. Results: There are no significant differences in genotype or allele distribution were identified between the patients and controls (p>0.05). The haplotypes constructed by four markers rs1317286, rs6494212, rs16969968, and rs684513 were not associated with schizophrenia either. However, a significant association between models made of rs1317286, rs1044396, rs6494212, and rs684513 and schizophrenia was revealed in interaction analysis (p<0.05). Conclusion The nAChR protein may have effects on the development of schizophrenia through the interaction with proteins encoded by schizophrenia-related susceptibility genes, but no relation was found between selected polymorphisms and schizophrenia in the collected Han Chinese people. However, interaction analysis suggested four-SNP model has an important effect on schizophrenia.
