OBJECTIVETo compare the difference in the clinical efficacy on cervical spondylosis between acupuncture at three lines of cervical Jiaji (EX-B 2) and oral administration of jingfukang granules.

METHODSThree hundred cases of cervical spondylosis were divided into an acupuncture group and a medication group, 150 cases in each one. In the acupuncture group, according to the different types of cervical spondylosis, acupuncture was applied at three lines of cervical Jiaji (EX-B 2), once a day. In the medication group, jingfukang granules were prescribed for oral administration, one bag each time, three times a day. The treatment of ten days made one session in the two groups and two sessions were required totally. Before and after two sessions of treatment, the clinical assessment scale for cervical spondylosis (CASCS) was adopted to evaluate the score of subjective symptoms, clinical physical signs and adaptability as well as the total score in the patients of the two groups and the efficacy was compared.

RESULTSThe patients' symptoms and physical signs were alleviated, the adaptability was improved and the score of each item and the total score were increased in the two groups after treatment (all P<0.01). The improvements in the acupuncture group were better than those in the medication group (all P<0.01). The curative and markedly effective rate was 90.7% (136/150) in the acupuncture group, better than 66.0% (99/150) in the medication group (P<0.01).

CONCLUSIONAcupuncture at three lines of cervical Jiaji (EX-B 2) achieves the significant clinical efficacy on cervical spondylosis. This therapy is superior to relieving symptoms and physical signs and recovering adaptability as compared with jingfukang granules.

OBJECTIVETo investigate the relationship between sensitivity to cisplatin (DDP) and the expression of HSP70 in cervical cancer cells in vitro.

METHODSCervical cancer Hela229 cells treated with different concentrations of DDP and the HSP70 inhibitor (PFT-µ) were examined for cell viability using MTT assay and colony forming ability. The cell apoptosis was analyzed by flow cytometry with propidium iodide staining and DAPI staining, and JC-1 staining was used to determine mitochondrial membrane potential. The expressions of HSP70, Bcl-2, Bax and caspase-3 were measured with Western blotting. A nude mouse model bearing Hela229 cell xenograft was used to evaluate the effect of DDP and PFT-µ on tumor growth.

RESULTSHela229 cells expressed a higher level of HSP70 than normal cervical cells. The combined use of PFT-µ significantly enhanced the inhibitory effect of DDP (P<0.01) and increased the cell apoptosis in Hela229 cells. JC-1 staining demonstrated that DDP combined with PFT-µ more obviously reduced mitochondrial membrane potential. DDP combined with PFT-µ more strongly lowered Bcl-2 expression and increased the expressions of casepase-3 and Bax than DDP alone. In the nude mouse model, PFT-µ significantly enhanced DDP sensitivity of Hela229 cell xenografts (P<0.01).

CONCLUSIONSInhibition of HSP70 expression can enhance the sensitivity of cervical cancer cell to DDP both in vivo and in vitro possibly by promoting cell apoptosis, suggesting the potential of HSP70 as a new target for gene therapy of cervical cancer.

Objective To analyze the different risks of cardia neoplasms in the immediate relatives of the cardia cancer patients,through a case-control study.Methods A case-control study was adopted on 772 cases and 772 controls,and relative risk (RR) were measured to compare the results from patemal or matrilineal groups.Results (1)Risk of the 1st grade kinship to the male cardia-cancer-patient group was obviously higher than that of the control group with RR=2.61 (95％CI:1.44-4.73,P＜0.01).(2) The risks of both paternal (P＜0.05) and matrilineal (P＜0.05) in the male cardia-cancer-patients were obviously higher than that of the control groups while the risk of those male cardia-cancer-patients in the paternal was higher than that of the control group (P＜0.05),so as the case for female patients in the matrilineal group (P＜0.05).(3) Data from the 1st grade kinship of cardia-cancer-patient group showed that parents and siblings had a higher risk than the control group (P＜0.05).(4) No significant genetic differences were found between the patemal of either the cancer group or the control group (P＞ 0.05),but statistical difference was observed that the risk of someone being the matrilineal of the cancer group was higher than that of the control group (P＜0.05).Conclusion The risks of cardia-cancer were higher in the 1st grade kinship,which including parents,brothers,sisters,maternal grandmother,mother,and maternal aunt.It was suggested that prevention programs should be focused on both earlier detection and treatment of the patients.New strategy for cancer prevention also need to be further developed.

Objective To explore the relationship between esophagus cancer patients and both environmental and genetic factors,through analyzing the data on birth orders from esophagus cancer patients of Shanxi province.Methods Both Greenwood and Haldane methods on birth order were used to study the 1101 cases with esophagus cancer from Shanxi province.All the patients had received surgery and were diagnosed,by pathological evidence.First certificates of the patients were confirmed through the standard genetic epidemiologic investigation.Birth order was investigated on probands of the 1101 cases with esophagus cancer and their 44 siblings.Results Results form the Greenwood method showed that there was a tendency for cases with esophagus cancer in birth orders First to Third.However,the Haldane method showed that the results were quite different between actual value and the average theory value of 6A (6A(actual value)=17 118,(X)6A(average theory value) =19 290,X=∣6A-(X)6A∣/√V6A =7.63,X ＞ 2) which suggested that the birth order had some effects on the occurrence of esophagus cancer.In addition,the actual value of 6A was lower than the theoretic average value,and the parents at younger productive age or baby at the first birth was easy to develop esophagus cancer.Conclusion Esophagus cancer was related with the birth order,especially at early order,which was not consistent with the national reports on esophagus cancer.Results from this study suggested that there were certain effects of environmental risk factors on esophagus cancer patients.

Objective To investigate the relationship between matrix metalloproteinase(MMP)1 gene-519A/G polymorphism and the risk of coronary heart disease(CHD)in Northern Chinese Han population.Methods A total of 517 patients with CHD and 380 healthy adults diagnosed by coronary angiography were genotyped by polymerase chain reaction-restriction fragment length polymorphism and DNA sequence technology for the-519A/G polymorphism in MMP1 gene.Results (1)The frequency of AA genotype was significantly higher in patients with CHD than that in controls[67.70%(350/517) vs.40.26%(153/380),OR=1.64,P＜0.001,95%CI:1.44-1.86].People carrying A allele had increased risk for CHD(OR=1.49,P＜0.001,95% CI:1.33-1.69).(2)The frequency of AA genotype was higher in patients with acute coronary syndrome(ACS)than patients with stable angina pectoris[68.81%(278/404)vs.51.76%(44/85,),P＜0.01,95% CI:1.04-1.27].The A allele carriers were more likely to develop ACS(OR=1.11,95% CI:1.01-1.21,P＜0.05).Conclusion Our data shows MMP1 gene -519A/G polymorphism is associated with the risk of CHD,and A allele carriers are more susceptible for CHD in Northern Chinese Han population.

OBJECTIVETo evaluate the efficacy of Bufei Yishen Granule BFYSG) combined with Shufei Tie acupoint sticking therapy on quality of life of patients with stable chronic obstructive pulmonary disease (COPD).

METHODSA multi-center, double-blinded, double-dummy and randomized controlled method was adopted in this trial. A total of 244 patients were randomly assigned to a trial group and a control group according to the random number, each with 122 patients; treatment allocation occurred when the participants met the inclusion criteria and signed the informed consent form. In the trial group, patients were treated with BFYSG combined with "Shufei Tie" acupoint sticking therapy and sustained-release theophylline dummy, and in the control group patients were treated with oral sustained-release theophylline and BFYSG dummy combined with "Shufei Tie" acupoint sticking therapy dummy. The therapeutic course for two groups was 4 months and the follow-up was 6 months. The frequency and duration of acute exacerbation calculated by adding up each frequency and duration of acute exacerbation in treatment and follow-up time respectively, the quality of life measured by the World Health Organization Quality of Life (WHOQOL)-BREF scale and adult COPD quality of life (COPD-QOL) scale were observed.

RESULTSAmong the 244 enrolled patients, 234 were screened for full analysis set (FAS); 221 were screened for per-protocol analysis set (PPS). After 4-month treatment and 6-month follow-up there were differences between the trial group and the control group in frequency of acute exacerbation (FAS: P=0.013; PPS: P=0.046); duration of acute exacerbation (FAS: P=0.005; PPS: P=0.006); scores of physiological, psychological and environment aspects of the WHOQOL-BREF questionnaire (FAS: P=0.002, P=0.006, P=0.000; PPS: P=0.00, P=0.001, P=0.000); scores of daily living ability, social activity, depression symptoms aspects of the COPD-QOL questionnaire (FAS: P=0.000, P=0.000, P=0.006; PPS: P=0.002, P=0.001, P=0.001).

CONCLUSIONBFYSG combined with acupoint sticking therapy could improve the quality of life of patients with stable COPD.

OBJECTIVETo evaluate two-dimensional gel electrophoresis (2DGE) and mass spectrometry in the studies of the serum proteins expressed in patients with BPH and those with high-grade prostatic intraepithelial neoplasm (HGPIN).

METHODSWe extracted serum proteins from BPH and HGPIN patients by 2DGE and cut the differentially expressed interesting protein spots from the gel. Then we digested the proteins, obtained the peptide mass fingerprint by mass spectrometry and identified the proteins through database retrieval.

RESULTSWe successfully achieved the 2DGE maps of the serum proteins from the BPH and HGPIN patients, obtained 1 421-1 532 protein spots from the 2D map of HGPIN and 1 466-1 778 from that of BPH. Based on peptide mass fingerprinting, 9 of the protein spots were identified. Serum amyloid A was found to be expressed in the HGPIN group, but weakly or not at all in the BPH.

CONCLUSIONProteomics can be applied to the study of the serum proteins in BPH and HGPIN patients. It can afford experimental evidence for the early diagnosis and development HGPIN, promote the search of functional and specific proteins of prostate diseases and shed new light on the network mechanisms of the problems.

The purpose of this study was to investigate the influence of nitro oxide (NO) from mesenchymal stem cells (MSC) on the proliferative responses of allogeneic lymphocytes and its mechanism. MSCs were isolated and cultured from human bone marrow. Selected surface antigens of MSCs were detected by flow cytometry and their morphologic characteristics were determined by microscopy. Mitomycin C-treated MSCs were plated in dishes and then mixed lymphocyte cultures (MLC) were set up. After 4 days, lymphocyte proliferation was determined by CCK-8 assays; NO secretion in coculture supernatant was determined by Griess reagent kit; the level of FOXP3 mRNA expression was detected by real-time quantitative PCR. The results indicated that in MSC/MLC coculture experiment, the lymphocyte proliferation decreased significantly with of IOD value 0.49+/-0.03, NO production increased obviously (21.05+/-1.14 micromol/L) and FOXP3 mRNA expression was increased [(1.56+/-0.34)%] as compared with MLC coculture without MSC. There were significant difference between these two groups. It is concluded that NO production in human MSC culture up-regulates FOXP3 mRNA expression and thus inhibits lymphocyte proliferation response.

OBJECTIVETo screen the molecular markers for refractory anemia with excess blasts in transformation (RAEB) in myelodysplastic syndromes (MDS) by serum proteome profiling.

METHODSThe serum protein were isolated from patients with RAEB, acute myeloid leukemia or normal subjects by 2-dimensional electrophoresis (2-DE), and the electrophoresis gels were obtained to identify the differentially reacting protein spots. The replica gels of the differentially reacting proteins were analyzed to locate the matching protein spots, which were identified by peptide mass fingerprint based on matrix-assisted laser desorption/ionization time of-flight mass spectrometry (MALDI-TOF-MS) and database searching.

RESULTSSeven differentially expressed proteins in RAEB were found by 2-DE. Of the 7 proteins, 4 were identified by MALDI-TOF-MS to have significantly differential expression in RAEB, including dipeptidyl peptidase (DPP/CD26), polymerase (DNA directed) kappa, PRO2044 and an albumin-like protein.

CONCLUSION2-DE-based serum proteome profiling helps identify serum proteomic biomarkers related to MDS. DDP/CD26 has increased expression in the serum in RAEB subtype MDS, suggesting its possible role in advanced MDS.
