Clinically, chronic obstructive pulmonary disease (COPD) and coronary heart disease (CAD) often interact to promote disease progression. This article discussed that zongqi is the heart-lung correlation functional basis and yingwei relevant is heart-lung correlation core. Zongqi deficiency is the incidence basis of COPD and CAD from the pathology. Communication and transformation of nutrient and defensive qi is the core mechanism of COPD combined with CAD. Phlegm and blood stasis are toxic intricate. Further damage to jingqi is the key to combination of COPD and CAD. It lays the foundation for next clinical syndrome differentiation, development of comprehensive treatment programs and clinical research.

Objective To study the correlation with ketamine and its metabolite norketamine concentration in plasma and saliva in acute toxic rabbits.Methods Experimental rabbits were given intragastric(i.g.group,n=6)and intravenous(i.v.group,n=6)administration of ketamine respectively,and control tabbits(n=6)were given a same volume of physiologic saline.The plasma and saliva were collected before and after ketamine administration.Ketamine and norketamine in plasma and saliva were determined using GC/MS and GC.The correlation with ketamine(norketamine)concentration in plasma and saliva were artalyzed by a double variable Pearson correlation analysis.Results The correlation coefficients(r)of ketamine (norketamine)concentrations in plasma and saliva were from 0.80 to 0.95 in ketamine i.g.group and i. v.group.Conclusion There is a good relativity between the concentration of ketamine(norketamine)in plasma and in saliva.The ketamine(norketamine)concentration in saliva can be used to estimate the plasma concentration in the forensic identification of ketamine abuse.

Objective To analyze the relationship between plasma aldosterone level and gestational diabetes melli?tus. Methods All subjects were divided into three groups (n=20 in each group):gestational diabetes mellitus (GDM) group, pregnancy with normal glucose group,non-pregnant healthy women group. Pre-pregnant body mass index (BMI) was calcu?lated, and fasting blood glucose (FBG), blood lipid level, Fins, HOMA-IR index, RASS, PRA, ATIi and ALD were examined besides glucose intolerance test. Results The plasma ALD level was significantly higher in GDM group than that of NGT group and control group(pmol/L:1 130.15±135.45 vs 1 053.98±108.86 vs 544.31±127.97). The plasma ALD level was posi?tively correlated with FBG,1 h PBG ,2 hPBG,Fins , HOMA-IR and blood triglyceride (r=0.657, 0.757, 0.713, 0.429,P<0.05),but negatively correlated with HDL-C(r=-0.267,P=0.039). Stepwise regression analysis revealed that plasma aldo?sterone was the independent risk factor of GDM. Conclusion RASS is excessively activated in pregnancy, which contrib?utes to gestational diabetes mellitus.

Objective To investigate the influence of ethanol on the toxicokinetic profiles of ketamine and its main metabolite norketamine in rabbits.Methods Ketamine hydroehloride Wills administered orally to the rabbits at a dose of 15mg/kg in the ketamine-treated group.Ketamine hydrochloride combined with ethanol at a dose of 15 mg/kg and 3.0g/kg respectively was administered orally to those of the ethanol-coadministration group.The serum and urine samples were collected before administration and at different time points after drug delivery.The concentrations of ketamine and norketamine were determined by GC and GC/MS.Compartment model and toxicokinetics parameters were assessed by WinNorLin program.Results The mean serum concentration-time profile of ketamine after oral administration was fitted to a two-compartment open model with first order kinetics and not affected by ethanol.The K_(10),AUC and β of ketamine in rabbits of ethanol-coadministration group increased as compared with those of ketamine-treated rabbits,while T_(1/2K_(10)),T_(1/2β),A and C_(max)decreased(P＜0.05).Meanwhile,the K01,A,B and C_(max) of norketamine,the metabolite of ketamine increased in ethanol-coadministration group and T_(1/2K01) and Tmax were lowered than those in ketaminetreated group(P＜0.05).Difference of the other toxicokinetics parameters including V/F,K_(10),K_(12),K_(21),AUC,T_(1/2K_(10)),T_(1/2α),T_(1/2β) and β were not statistically significant between two groups(P＞0.05).Conclusion Ethanol may accelerate elimination of ketamine and the metabolism of ketamine to norketamine and has little effect on the absorption of ketamine,suggesting that interaction between ethanol and ketamine should be considered in cases of co-abuse of the two drugs.

Objective To investigate the possible mechanism of mitochondrial in chronic myeloid leukemia cells K562/G01 cells apoptosis induced by triptolide.Methods K562/G01 cells were treated with different concentrations of triptolide.MTT assay was used to assess cytotoxic effect.FCM was used to determine apoptosis rate,mitochondrial membrane potential and the activity of Caspase-9 of each experimental group.Real-time quantitative PCR assay was used to quantify mRNA levels of Caspase-9 and cytochrome C and Western blot assay was used to determine protein levels of cytochrome C.Results Triptolide inhibited the growth and proliferation of K562/G01 cells in a time-and dose-dependent manner (both P ＜ 0.001).Meantime,triptolide could make the mitochondria membrane potential fade away and enhance the activity of Caspase-9 (F =566.431,2 555.485,P ＜ 0.001).In addition,triptolide could dose-dependently up-regulated the transcription of Caspase-9 and cytochrome C (F =61 007.702,452 121.760,P ＜ 0.001),and the protein expression of cytochrome C,whose gray value in each experimental group was 21.54±0.59,39.63±0.58,53.29± 1.47 and 75.68±1.87 (F =5 677.928,P ＜ 0.001) respectively.Conclusion Triptolide could potently inhibit the growth and proliferation of K562/G01 cells,and the mitochondria apoptosis pathway might be one of the important apoptosis mechanisms in chronic myeloid leukemia cells induced by triptolide.

Background and purpose:Esophageal cancer(EC) is one of the most common cancers that account for cancer-related deaths and over 400,000 new cases has been diagnosed per year.The morbility of small cell carcinoma of the esophagus(SCEC) is very low.This paper was to study was the clinical characteristics,treatment and prognosis of undifferentiated small cell carcinoma of the esophagus(SCEC).Methods:From 1961 to 2003,743 patients with SCEC were treated in different hospitals.The number of small cell carcinoma of the esophagus seen accounted for 1.38% of esophageal cancer treated in those hospitals in the same period.the average age was 56.8(range,51 to 66).511 of patients were male and 232 female.2 of them had primary tumor in the cervical proportion of the esophagus,68 in the upper thoracic proportion,420 in the mid thoracic proportion,252 in the lower proportion and 1 in the whole esophagus.88 patients were treated by surgery alone,23 by radiotherapy alone,24 patients by chemotherapy alone and all other of patients were treated by combined modality.Results:The median survival was 12.4 months for all patients,with 10.8 months for surgery,6.2 months for radiotherapy,6.6 months for chemotherapy,14.7 months for surgery combined with radiotherapy,16.1 months for surgery combined with chemotherapy,12.3 months for chemoradiotherapy and 16.2 months for surgery combined with chemoradiotherapy,respectively.The survival rates at 1,2,3,4,and 5 years were 56.4%、27%、19.3%、11.1%、(9.7%) for the whole group,respectively.Conclusions:We recommend that combined modality should be used for SCEC.The combination of surgery and multi-drug chemotherapy may improve the treatment outcomes for the patients with early stage SCEC.

Objective To evaluate the epileptic focus localization value of MSI in patients with refractory epilepsy and encephalomalacia. Method MSI examination was proceeded in 11 patients with refractory epilepsy and encephalomalacia. Five of them were treated with gamma-knife; the others were treated with surgery. Results In the five patients treated with gamma-knife, the result was satisfied in 3 patients, one patient improved significantly, the other one useless. The distance between the encephalomalacia and the epileptic focus was 4cm in one patient; one patient′s encephalomalacia was located in right frontal-parietal lobe but the epileptic focus mainly located in right temporal lobe, only a little located around the encephalomalacia. Overall agreement among VEEG,ECoG and MEG (presence of concordant spikes with the same localization shown by three techniques) was obtained in three patients, the areas localized by ECoG were larger than VEEG and MSI in two patients. The localization was different in VEEG, MSI and ECoG in one patient, then he was given a resection of bilateral occipital epileptic focus. The results of patients treated with surgery were satisfied. Conclusion The MSI localization of epileptic focus in patients with refractory epilepsy and encephalomalacia is precise, and it can direct the advanced clinical treatment.

Objective To investigate the quality of life of elderly caregivers and its factors. Methods Elderly caregivers living in Changzhi City were enrolled in this study. 36-item short-form (SF-36) health survey and Activity of Daily Living Scale ( ADL) were used as study tools. The data was analyzed by statistical description,t test or multiple regression. Results Those with score of quality of life reaching 72. 1 to 117. 0 accounted for 98. 8%. The total score and score of eight dimensions of SF-36 showed statistically significant difference between different daily living activity groups ( P < 0.05) . The state of health and self-care ability of the elderly imposed a major impact on eight dimensions of SF-36. Age, sex, level of education, marital status and wage had different impact on each dimension of SF-36. Conclusion The quality of life of elderly caregivers is at a medium level. The main factors of quality of live of elderly caregiver are their state of health and self-care ability of the elderly.

Objective To investigate the status of life quality in the elderly in Shanxi Province Changzhi City, and to analyze its influencing factors. Methods The quality of life, activities of daily living and status of community services were measured simultaneously by 36-Item Short Form Health Survey (SF-36). Activities of Daily Living Scale, Community Healthy Needs Scale and survey results were used and analyzed using t-test, correlation and stepwise regression analysis. Results According to the criterion of life quality in the elderly which were proposed by Zhang Lei, the quality of life in the elderly scored 72. 1-117.0, reached 98.5%. The quality of life in the elderly was impacted by the ability of caring oneself, marital status, degree of culture, economic situation and so on. The demand rate for health guidance and periodic physical examination was higher. Conclusions The quality of life in the elderly is at a medium level. There is a wide gap between the demand of community healthy services and the utilization of community healthy services.

Objective To assess the clinical significance of detecting the immune markers in idiopathic thrombocytopenic purpura (ITP). Methods The frequencies of circulating B cells secreting platelet-specific antibody, platelet-specific antibody, the percentage of T lymphocyte subsets, the percentage of reticulated platelet and the level of thrombopoietin in 64 ITP patients and 31 healthy controls were measured with enzyme-linked immunospot assay (ELISPOT),modified monoclonal antibody immunobilization of platelet antigens assay (MAIPA), flow cytometry and sandwich enzyme-linked innnunosorbent assay respectively. Results Compared with the controls[1.3 ± 0. 5/105 peripheral blood mononuclear cell (PBMC), (0.33±0.06,0.41±0.03), (22.08±4.54)% and (8.19±2.46)%], the frequencies of circulating B cells secreting platelet-specific antibody (7.6±4.6/105 PBMC in acute ITP group, 5.3±3.0/105 PBMC in chronic ITP group), platelet-specific antibody (including the anti-GP Ⅱ b/Ⅲa antibody, anti-GP Ⅰ b/X antibody) (0.51 ±0.11, 0.48±0.06 in acute ITP group; 0.49±0.10,0.46±0.09 in chronic ITP group), the percentage of CD8+ T Lymphocyte (27.09±9.86 ) %, the percentage of reticulated platelet in ITP patients[the megakaryocyte cytosis group (24. 85 ± 19. 18)%, the normal megakaryocyte group (23.89±18.90)%]were significantly increased ( all P＜0.05).The frequencies of circulating B cells secreting platelet-specific antibody in acute ITP patients were notably increased (P＜0.05) compared to the chronic ITP patients. In T lymphocyte subsets, the percentage of CD3+T lymphocyte and CD4+ T lymphocyte and the ratio of CD4+/CD8+ in the patients with ITP[(60.88±14.59)%, (28.41±10.55)%, 1.18±0.59]were notably decreased than those in the healthy controls [(69.89±6.43)%, (35.38±5.05) %, 1.64±0.29, P＜0.05]. There was no apparent difference of the level of thrombopoietin between ITP patients with megakaryocyte cytosis (72. 09 ± 41.64 ) and health controls (75.37± 26. 32, P ＞ 0. 05 ), however, the level of thrombopoietin of ITP patients with normal megakaryocyte apparently increased (118.60±70.72, P＜0.05). Conclusion Detecting the frequencies of circulating B cells secreting platelet-specific antibody, platelet-specific antibody, the percentage of T lymphocyte subsets, the percentage of reticulated platelet and the level of thrombepoietin in the patients with ITP may improve the diagnosis and guide clinical therapy.
