Objective:It was a part of an overall study of the clinical research literature about ischemic cerebrovascular disease treated by various acupuncture techniques,namely "restoring consciousness and inducing resuscitation technique","needling Baihui(DU20) through Qubin(GB7)","Jiao’s three-needle technique" and "temporal three-needle technique".The papers collection for analysis were designed on the random,control and blind methods.Methods: A data bank was set up with Access 2003.A statistical analysis was made for the method of employing ratio and constituent ratio about the research literature mamaged with the ramdom,control and blind methods.Results: The ratio of those that were designed randomly is as follows: the "restoring consciousness and inducing resuscitation technique"(50%),"needling Baihui(DU20) through Qubin(GB7)"(100%)(Only two articles meet the request and futher exploration is needed),and the "temporal three-needle technique"(50%).And the "Jiao’s three-needle technique"(40%).The ratio of those that were designed with the control method is as follows: the "restoring consciousness and inducing resuscitation technique"(60%),"needling Baihui(DU20) through Qubin(GB7)"(100%)(Only two articles meet the request and further exploration is needed,the "temporal three-needle technique"(75%),and "Jiao’s three-needle technique"(70%).The blind method was not used.Conclusion: It is suggested that the three methods should be stressed in the study of acupuncture in the treatment of ischemic cerebrocvascular disease.Only in this way,can there be a maximum comparability and the sampling error is decreased.The bias due to subjective factors of the researchers and subjects can be overcome.

Objective To evaluate the relationship of peripheral blood Th17 and regulatory T (Treg) cells with disease activity in patients with systemic sclerosis (SSc).Methods This study recruited 21 patients with active SSc,24 patients with inactive SSc and 24 normal human controls with informed consent.Peripheral blood samples were obtained from these subjects.Flow cytometry was used to detect the percentages of Th17 and Treg cells in peripheral blood CD4+ cells,a fluorescence-based quantitative PCR to determine the levels of interleukin (IL)-17A,retinoid-related orphan receptor gamma t (RoRγt),forkhead box P3 (FoxP3) mRNA in peripheral blood mononuclear cells (PMBCs),and enzyme linked immunosorbent assay to measure the serum level of IL-17.Results Increased percentage of Th17 cells in peripheral blood CD4+ cells was observed in patients with active SSc compared with those with inactive SSc and normal human controls (2.34％ ± 1.19％vs.0.68％ ± 0.39％ and 0.57％ ± 0.49％,respectively,both P ＜ 0.05).No statistical difference was noted in the percentage of Treg cells in CD4+ cells or the mRNA expression levels of FoxP3 between the patients with active SSc,inactive SSc and normal human controls (all P ＞ 0.05).There was a significant increase in the mRNA expression of IL-17A,RoRγt in PBMCs and serum levels of IL-17 in patients with active SSc compared with patients with inactive SSc and normal human controls ( 11.73 ± 0.80 vs.9.77 ± 1.30 and 10.79 ± 0.74,respectively,both P ＜ 0.05; 18.48 ± 1.09 vs.15.89 ± 1.48 and 17.77 ± 1.64,respectively,both P ＜ 0.05; 53.60± 9.90 pg/ml vs.15.18 ± 3.24 pg/ml and 15.53 ± 4.12 pg/ml,respectively,both P ＜ 0.05).The percentage of Th17 cells in CD4+ cells and serum IL-17 levels were both positively correlated with disease activity in patients with active SSc (r =0.675,0.644,respectively,both P ＜ 0.05).Conclusions Th17 cells are highly proliferative in patients with active SSc,which may be closely correlated with the activity of SSc.

Objective: To improve clinical utility of the Nurses Observation Sca le for Inpatient Evaluation (NOSIE-30) in China. Methods: Based on the original scale, which only provides names and ranked scores for items, we developed clear definitions for each item and anchoring descriptions for score rating. 164 firs t-episode schizophrenic patients were evaluated with this scale every two weeks after admission. A total of 994 evaluations were completed. The collected data w ere randomly divided into two independent data sets. The number and content of t he subscales were revised based on principal component factor analysis and item analysis of the first data set. The revised scale was then evaluated and compare d with the original 7-subscale version of the instrument using the second data s et. Results: Factor analysis found that the factor structu re of the revised scal e was markedly different from that of the original instrument. Item analysis res ulted in elimination of 30 original items and redistribution of the remaining 26 items into 5 subscales. Comparison of the revised scale with the original instr ument revealed better psychometric properties for the former than the latter.Conclusion: The subscale scores of the original 7-subscale v ersion of NOSIE-30 did not reflect independent symptom clusters in Chinese schizophrenic inpatients. T o improve the usefulness of the scale in China, the present study recommended a better revised scale with re-definition of items into 5 subscales.

Two-dimensional electrophoresis(2-DE) is an important technique in proteomics research.The 2-DE system for proteome of Monascus ruber was established by comparing and analyzing the infection caused by different kinds of mediums,lysis buffer and the condition of rehydration.By cultivating the Monascus ruber with YES for 6 days,extracting total protein by TCA-acetone,lysis buffer with 8 mol/L urea,2 mol/L thiourea,4 % CHAPS,1 % DTT and 2 % Bio-lyte,an ideal 2-DE map with higher resolution and better legibility was obtained,which laid a foundation for the further studies on proteome of Monascus ruber.

Conclusion Within certain concentration range of thalidomide can inhibit the level of VEGF mRNA expression in breast cancer cell.

Objective To observe the expression and significance of hypoxia inducible factor (HIF)-1α,matrix metalloproteinase(MMP)-9 and transforming growth factor(TGF)-β1 in liver tissues of rats with hepatic fibrosis and the effects of TGF-β1 vaccine on the expressions of HIF-1α,MMP-9 and TGF-β1.Methods The hepatic fibrosis rat model was set up by dimethylnitrosamine (DMN).The rat model was injected with TGF-β1 vaccine.The expressions of HIF-1α,MMP-9 and TGF-β1 were detected by immunohistochemistry in rat fibrosis tissues after 6 weeks.Results The expressions of HIF-1α,MMP-9 and TGF-β1 in fibrosis model group and TGF-β1 vaccine group were all significantly higher than control group(P＜0.01),which was positively correlated with the fibrosis degree(r=0.911,0.814 and 0.836,respectively,P＜0.01).However,the expressions of HIF-1α,MMP-9 and TGF-β1 in TGF-β1 vaccine group were all significantly decreased than fibrosis model group (t=2.62,4.03,3.43;P＜0.01).Conclusion During the development of liver fibrosis,HIF-1α promotes the transcriptions and expressions of MMP-9 and TGF-β1.

Background:Resistance of Helicobacter pylori(Hp)to antibiotics is the primary reason for failure of Hp eradication therapies. It has been reported that there are regional differences in the resistance rate of Hp to commonly used antibiotics. Monitoring the regional Hp resistance status is helpful for improving the eradication rate in local area. Aims:To investigate the resistant spectrum of clinical Hp strains to commonly used antibiotics in Jiaxing Area,Zhejiang Province. Methods:A total of 17 402 patients who underwent gastroscopy from Jan. 2009 to Dec. 2013 at Jiaxing First Hospital were recruited for Hp culturing by using gastric antral biopsies. Then a drug sensitive test was performed for the Hp strains obtained from the culturing. Sensitivity of these Hp strains to metronidazole,amoxicillin,gentamicin,furazolidone,clarithromycin and levofloxacin was determined. Results:Among the 17 402 cases of gastric antral biopsies,5 898(33. 9% )were positive for Hp culturing. Drug sensitive test revealed that the resistance rate of metronidazole was extremely high in all year and age groups;the resistance rates of clarithromycin and levofloxacin were increasing by years;and the resistance rates of furazolidone,amoxicillin and gentamicin were considerably low in all year and age groups. When two antibiotics were combined,amoxicillin and gentamicin accounted for the lowest resistance rate,and the next were amoxicillin and furazolidone,and gentamicin and furazolidone,respectively. Conclusions:The clinical Hp strains isolated from all age groups in Jiaxing Area,Zhejiang Province are highly resistant to metronidazole,therefore it is not recommended to be used in first line eradication regimen. Amoxicillin combined with gentamicin/ furazolidone is an ideal antibiotic combination for patients with Hp infection in all age groups;and combination of gentamicin and furazolidone is recommended to patients who are allergic to penicillin.

Objective To investigate condition of single drug or multiple drug resistance and sensitivities of different combinations of antibiotics in Helicobacter pylori (H.pylori) infected patients of different ages in Jiaxing City,Zhejiang Province.Methods From January 2007 to December 2011,a total of 6280 patients underwent gastroendoscopy examination were enrolled,the average age of them was 50.8 years old.Among them,129 cases were less than 20 years old,1802 cases were between 20 and 40,3016 cases were between 40 and 60,and 1333 cases were over 60.The mucosa of gastric antrum was collected for H.pylori culture.Drug sensitivity of isolated H.pylori strains was tested with metronidazole,amoxicillin and gentamycin,furazolidone,clarithromycin and levofloxacin.x2 test was performed for the comparison of drug resistance among different age groups.Results Among 6280 specimens,H.pylori culture of 2311 cases was positive (positive rate 36.80％).The positive rate of patients aged between 40 and 60 was the highest (38.43％,1159/3016),and that of patients over 60 was the lowest (33.76％,450/1333).The drug resistance rate of metronidazole in patients between 20 and 40 years reached 98.02％ (644/657) and was the highest.The drug resistance rate of clarithromycin in patents over 60 years old was the highest,which was 22.67％(102/450).The drug resistance rates of the levofloxacin,furazolidone,amoxicillin and gentamicin were low of all ages.Mixed resistance of two antibiotic appeared in 586 strains,mixed resistance rate of metronidazole and clarithromycin was the highest (259 strains,15.23 ％).Mixed resistance of three drugs appeared in 49 strains,mixed resistance rate of metronidazole,clarithromycin and levofloxacin was the highest (32 strains,12.88％).A total of 1691 strains were sensitive to the combination of amoxicillin and gentamycin,the sensitive was rate 99.41％.The sensitive rate of the combination of amoxicillin and furazolidone,gentamycin and furazolidone was both 94.24％.Conclusions Metronidazole presented high drug resistance of all ages,and should not be chosen.The combination use of amoxicillin and gentamicin is the ideal antibiotic combination for different ages.The combination of gentamycin and furazolidone is recommended for patients who are allergic to penicillin.

Objective To study local people's habits and customs concerning the prevention of dental fluorosis in an indoor coal-combustion-type fluorosis area of Zhaotong city Yunnan province, and to provide reference value for monitoring and control of the disease. Methods In 2008, 600 people of a 12-year-old group (400 people) and a 35 - 44-year-old group(200 people) were examined for dental fluorosis and oral health status in an indoor coal-combustion-type fluorosis area of Zhaotong. A questionnaire survey of 120 students and 60 adults was carried out on their habits and customs, stove changing status, knowledge of prevention of dental fluorosis, social psychology status, oral health behavior and their need for medical treatment. Results The total prevalence of dental fluorosis was 91.0% (546/600), dental fluorosis index was 2.58. The total prevalence of dental fluorosis of 12-year-old group was 86.5%(346/400), and dental fluorosis index was 2.12. The total prevalence of dental fluorosis of rural student was 90.5% (181/200), which was obviously higher in the rural group than the urban group [82.5% (165/200), χ2 = 5.48, P < 0.05]. The total prevalence of dental fluorosis of 35-44-year-old group was 100% (200/200), which was obviously higher than that of the 12-year-old group(χ2 = 29.67, P < 0.01). The rates of using coal, baking of food, changing stoves were 66.7% (60/90), 14.4% (13/90),57.8% (52/90), respectively, and these values of the urban were much lower than those of the rural[95.6%(86/90) ,31.1%(28/90) ,76.7%(69/90),χ2 = 24.51,7.11,7.29, all P < 0.01]. Only 23.3% (42/180) of people surveied had the knowledge of prevention of dental fluorosis, and the rate in the adult group[56.7% (34/60)]was higher than that of the student group [6.7% (8/120), χ2 = 55.9, P < 0.01]. The same rate in the urban student group was 0(0/60), and the rural student group was 13.3%(8/60), there was a significant difference between them(χ2 = 5.66, P < 0.05). Seventy-three point nine per cent( 133/180) of these people thought dental fluorosis had significant effect on their life, 91.1%(164/180) of these 'people wished to be treated. Eighty-four point four per cent( 152/180) of the people had a habit of toothbrushing,and 50.7% (77/152) of these people were still using toothpaste containing fluorine. Conclusions Zhaotong is a serious indoor coal-combustion-type fluorosis area. Enhancing health education to local people especially to students, and changing people's unhealthy habits and customs are keies to control the prevalence of indoor coal-combustion-type dental fluorosis.
