Background The circulating endothelial progenitor cells (EPCs)play an important role in postnatal vasculogenesis and restoration of endothelial injury.Previous investigation illustrated that a reduced ocular blood flow and vascular dysfunction caused by endothelial dysfunction plays a role in the pathogenesis of glaucoma.However,endothelial system accommodation is accomplished with the circulating EPCs.Objective The present trail was to investigate EPCs change in patients with primary acute angle-closure glaucoma (PACG)and explore the role of EPCs in the pathogenesis of PACG. MethodsA prospective cohort study was designed.Thirty patients with PACG were enrolled in Tianjin Medical University General Hospital as PACG group,and 20 normal subjects served as control group.Periphery bloodsamples were obtained fromall the patients and thenstained with saturating concentrations of monoclonal antibodies,FITC-conjugated anti-CD34 and CD133 mAb.EPCs identified by CD34,CD133 were enumerated by flow cytometry,and the correlation between EPCs change and its relative factors was analyzed.Informed consent was obtained from each subject before any medical procedure. Results No significant differences were found in age,gender,vascular-related risk factor,blood biochemical indicators between PACG group and normal contol group(P＞0.05 ),but a higher intraocular pressure( IOP)was displayed in PACG group compared with normal control group ( P =0.00 ).The numbers of EPCs were ( 48 ± 22 ) cells/ml in PACG group and ( 65 ± 20 )cells/ml in normal control group with a significant difference between them (P=0.004).In PACG group,the numbers of EPCs were(60± 19 )cells/ml and (34 ±7 )cells/ml respeetively in phase 1 and phase 3 of optical nerve damage (Z=-3.015,P=0.002 ).There was a negative correlation between EPCs numbers and baseline IOP within a certain range( r=-0.835,P＜0.05 ).However,no obvious correlations were seen between EPCs numbers and blood lipid Level,blood glucose level or glaucoma course ( r =0.343,P =0.227 ; r =-0.203,P =0.419 ; r =0.198,P =0.610 ).The EPCs numbers in PACG patients with cardiovascular disease were(56±22)cells/ml and that of without PACG were (35± 15 ) cells/ml( P =0.005 ). ConclusionsThe numbers of EPCs decrease in PACG patient.These results imply that EPCs might play role during the restore of the optical nerve damage in PACG eye.

OBJECTIVETo compare the difference in clinical efficacy on chronic obstructive pulmonary disease (COPD) at stable stage in the patients among the combined therapy of cutting method and western medication (combined therapy), simple cutting method and simple western medication.

METHODSOne hundred and twenty cases of COPD were randomized into three groups, 40 cases in each one. In the cutting method group, for excessive phlegm pattern/syndrome, Feishu (BL 13), Danzhong (CV 17), Dingchuan (EX-B 1) and Yuji (LU 10) were selected as the main acupoints, and Lieque (LU 7) and Pianli (LI 6) were as the supplementary acupoints. For the pattern/syndrome of failure to consolidate kidney primary, Shenshu (BL 23), Pishu (BL 20), Guanyuan (CV 4) and Yuji (LU 10) were selected as main acupoints, and Jueyinshu (BL 14) and Zusanli (ST 36) were as the supplementary acupoint. Three acupoints were selected alternatively in each treatment and the cutting method was applied once every 10 days. Three treatments made one session. Two sessions of treatment were required. In the western medication group, salbutamol sulfate aerosol, one press (200 μg/press) was used each night, as well as salmeterol xinafoate and fluticasone propionate powder for inhalation, one inhalation each night. The treatment of 1 month made one session. Two sessions were required. In the combined therapy group, the cutting method and western medication were applied in combination. The results of clinical symptom score, lung function test, arterial blood gas analysis, degree of inflation as well as clinical efficacy were observed before and after treatment in each group.

RESULTSExcept the degree of lung inflation, the clinical symptom score, indices of lung function test, partial pressure of arterial blood gas (PaO2) and partial pressure of carbon dioxide (PaCO2) were all obviously improved after treatment as compared with those before treatment in each group (all P<0.05). They were apparently improved after treatment in the combined therapy group and the cutting method group as compared with those in the western medication group (all P<0.05). The total effective rate was 77.5% (31/40) in the combined therapy group and was 75.0% (30/40) in the cutting method group, both better than 60.0% (24/40) in the western medication group (both P<0.05).

CONCLUSIONThe simple cutting method based on syndrome differentiation and the combined therapy with western medication achieve the superior efficacy on COPD at stable stage as compared with the simple western medication. The effect mechanism is possibly related to the improvement of bronchial airway function through constant acupoint stimulation.

In order to promote the Shenqifuzheng injection (SQFZ) clinical medication safety, this study reevaluate on SQFZ post marketing safety study systematically. Including multi center large sample registration type safety monitoring research, the analysis based on national spontaneous reporting system data, the analysis based on the 20 national hospital information system data and literature research. Above the analysis, it suggests that SQFZ has good security. The more adverse drug reaction (ADR) as allergic reactions, mainly involved in the damage of skin, appendages and its systemic damage, serious person can appear allergic shock. ADR/E is more common in the elderly, may be related to medication (tumor) populations. Early warning analysis based on SRS data and literature research are of the view that "phlebitis" has a strong association with SQFZ used.

The RAS (rat sarcoma) gene is one of the important oncogenes, and its mutation is present in about 30% human tumors. KRAS (kirsten rat sarcoma viral oncogene) is one of the three RAS subtypes, and KRAS mutations are more common than the mutations in other two RAS subtypes. In recent years, with the continuous research, new ideas have been provided for the treatment of cancers via targeting-KRAS. Efforts have been made to develop various KRAS inhibitors. Here, based on the mechanism of action, we classified KRAS inhibitors into two categories: inhibitors that directly target KRAS and inhibitors that indirectly act on KRAS. The representative KRAS inhibitors were summarized and introduced in this paper.

OBJECTIVEObserve and analyze the informations of western medicine and traditional Chinese medicine in patients with coronary heart disease (CHD), in order to provide reference for clinical treatment.

METHODSelect patients with CHD in diagnosis of the first place in 17 hospitals, drug informations of these patients were analyzed using frequency method and association rules.

RESULTIn 84 697 patients,there were 47 564 males and 32 882 females. The median age was 71 years old, 76 172 patients have medicine records, including 278 kinds of western medicine and 331 kinds of traditional Chinese medicine. Aspirin was the most common used western medicine (51 132 patients, 67.08%), followed by isosorbide dinitrate, clopidogrel etc. The most common used traditional Chinese medicine was danhong injection, followed by shuxuetong injection. After classified the drugs, at the forefront of western medicine were antiplatelet drugs, nitrates drugs, statins, beta blockers, calcium antagonists, ACEI; the most used in traditional Chinese medicine was injection of blood-activating and stasis-resolving, followed by oral preparations of blood-activating and stasis-resolving medicine, Fuzheng class oral medicine, purgation medicine etc. After association rules, combination therapy among western medicine was the most common, combination of western medicine with blood-activating and stasis-resolving was very commonly, especially antiplatelet drugs and nitrates drugs.

CONCLUSIONWestern medicine in the treatment of patients with CHD was in accordance with the guidelines recommend, but with the lower utilization rate. Traditional Chinese medicine has become an important method for the treatment of CHD, promoting blood circulation and removing blood stasis is an important part of traditional Chinese medicine treatment in patients with CHD.

Objective To explore protective effect of Heme oxygenase-1(HO-1) on irradiation-induced endothelial cell apoptosis.Methods Human endothelial cell line EA.hy926 were administered with or without HO-1 activator Copp and/or HO-1 inhibitor Znpp,respectively.Then,cells were treated with or without 8 Gy radiation.The HO-1 protein expression of cells were assessed with Western blotting and apoptosis of cells treated with irradiation were evaluated with flow cytometry.Moreover,cytochrome C releasing into cytosol were also determined by Western blotting. Results In PBS+R group,HO-1 protein expression of EA.hy926 was low posterior to irradiation.When cells were preconditioned with Copp and/or Znpp,then recieved with 8Gy irradiation,the HO-1 protein expression of EA.hy926 increased significantly in comparision with the PBS+R group(P

Objective To make up an exercise prescription based on traditional Chinese medical training (EP-TCMT) for patients with stable chronic obstructive pulmonary disease (COPD).Methods Eighty-five pa- tients with stable COPD were randomly divided into a control group (CG group),a traditional Chinese medicine group ( TC group) and an exercise prescription group ( EP group).The patients in the TC and EP groups were giv- en intensive training for 8 weeks.Their 6 rain walk distance (6MWD) and Borg scale scores were assessed before and after the treatment.Results The 6MWD in the TC group increased from 337.68?59.18 m to 386.14?76.71 m,while those in the EP group improved from 348.00?55.94 m to 425.17?53.22 m.The Borg scale scores in the TC group decreased from 3.14?1.94 to 2.32?1.25,while those in the EP group declined from 3.45?1.84 to 1.72?0.70.Conclusion Making up EP-TCMTs is feasible.Additional treatment was found to improve exercise tolerance and decrease dyspnea in COPD patients.Exercise therapy based on traditional Chinese methods is easy and safe.

Objective To evaluate the pattern of energy metabolism and nutrients intake in patients with chronic viral hepatitis and posthepatitic cirrhosis to effectively direct their nutrition therapy.Methods Resting energy expenditure (REE) was measured with open-circuit indirect Jorimetry in 60 patients with chronic viral hepatitis and 60 patients with posthepatitic cirrhosis.Their normal basal energy expenditure (BEE) was predicted by Harris-Benedict equation and energy intake (EI) was determined by diet recall. Correlation between REE and indicators for nutrition assessment was analyzed.Results REE was (77? 21) kJ?kg~(-1)?d~(-1) in 60 patients with pusthepatitic cirrhosis,significantly lower than BEE[(95?16) kJ? kg~(-1)?d~(-1)(P0.05,and their EI was (127?34) kJ?kg~(-1)?d~(-1),1.41?0.43 times as REE,in which PROI was (1.02?0.29) g?kg~(-1)?d~(-1),1.31?0.61 times as PROE (0.87?0.34) g?kg~(-1)?d~(-1),also indicating a negative nitrogen balance (-2.02?4.07).REE,EI and intake of three nutrients,serum level of albumin and prealbumin (PA) and body weight significantly decreased in patients with posthepatitic cirrhosis,as compared to those in patients with chronic viral hepatitis (P

Mycoplasma hyopneumoniae (M .hyopneumoniae) and Mycoplasma hyorhinis (M .hyorhinis) infections are common in China .To investigate the prevalence of M .hyorhinis and M .hyopneumoniae in Jiangsu Province of China ,a mo-lecular epidemiological survey was conducted from 399 nasal swab samples of unvaccinated pigs using nested Polymerase Chain Reaction (nested PCR) .Nasal swab samples were collected from Jiangquhai porcine lean (JQHPL) strain pigs and other West-ern breeds .Clinical samples were taken from each pig and divided into different groups based on ages of pigs (7 ,14 ,21 ,28 , and 35 days) .Results indicated that the prevalence of M .hyorhinis was 70 .9% from different herds in Jiangsu Province in China ,while the prevalence of M .hyopneumoniae was 13 .5% .M .hyorhinis infection was more common in pigs for less than 5 weeks of age compared to M .hyopneumoniae infection .Co-infection was also observed in 30 samples (7 .5% ) in which both M .hyorhinis and M .hyopneumoniae were detected .The M .hyorhinis infection increased as the animals grew from 7 to 35 days .The M .hyopneumoniae infection did not change significantly as the pigs grew older .Significant difference of M .hyorhi-nis infection was observed between other Western breeds and JQHPL pigs (P<0 .001) .JQHPL pigs appear to be more sensi-tive to the M .hyorhinis infection as compared to the other Western breeds .However ,there is no obvious relationship between the breed type and M .hyopneumoniae infection (P>0 .05) .

OBJECTIVESTo analyze the survival rate of nasopharyngeal carcinoma (NPC) and to evaluate the effect of intervention in this high risk population of NPC.

METHODSBased on the cancer and vital registry systems, the follow-up data of 1761 NPC cases were collected. The measures of survival include 5-year, 10-year survival rate and median survival duration. Cox model was used to screen the independent prognosis factors.

RESULTSThe 5-year and 10-year survival rates of NPC cases in Sihui were 50.62% and 37.01%, and the median survival duration was 5.05 years. The survival rate of NPC cases diagnosed after 1993 was 58.8%, which was higher than that of cases diagnosed before 1993 (43.3%). Other prognosis factors included gender, age, clinical stage and diagnostic hospital.

CONCLUSIONThere is a significant improvement of NPC survival in Sihui. That is mainly related to the improvement of NPC treatment. However, it needs to a long time observation to see a mortality reduction of NPC.
