Esophageal cancer treatment mode has currently been transformed from surgery alone to multidisciplinary treatment mo-dalities based on the standardization of operation in combination with the reasonable application of perioperative radiotherapy, che-motherapy, and other comprehensive treatment. Although controversies concerning accurate preoperative staging, surgical approach, extent of lymph node dissection, and perioperative chemotherapy regimens still exist, a multidisciplinary team can provide an optimal mode of diagnosis and treatment. A multidisciplinary approach embodies individualized tumor treatment and standardization princi-ple to the maximum extent, as well as prolongs patients' survival time and improves the quality of life.

JINLANBAO (JLB), a preparation extracted from the Pecten Argopecten irradiaus and some Chinese medicinal herbs,has been reported to have several immuno-mod-ulatory effects in mice In this paper,the influence of JLB on the immuivlogcai functions in mice is presented. The results showed that JLB could enhance the phagocytosis of intraperi-toneal macrophages (Mo) inhibited by methyl-prednisone,increase the IgM level in CTX-de-pressed cells in a dose-dependent manner in the medium-dose and high-dose group. JLB has been found to have a two-way regulatory effect on ConA-induced T-lyrophocytes prolifera tion, tea promoting effect in low dose group,and an inhibiting effect in high dose group. As an immunopotentiator, the potential values and prospects for the developing of JLB should be paid attention to in pharmaceutical sciences.

Objective To observe and compare the changes of Intermedin's contents in plasma and bron-choalveolar lavage fluid (BALF) in rats with hypoxic pulmonary hypertension. Methods male Wistar rats were ran-domly divided into control group and 1,2 and 3 weeks hypoxia group. Intermedin's contents in plasma and bronchoal-veolar lavage fluid were measured by radioimmunoassay. Results Intermedin's contents in plasma and bronchoalveo-lar lavage fluid were markedly increaseded compared with control group. Meanwhile transformational trend is consist-ent between plasma and bronchoalveolar lavage. Conclusions Intermedin's contents in plasma and bronchoalveolar lavage increase ,which shows that there is protection and moderation to hypoxic pulmonary hypertension.

Objective To discuss the risk factors and clinical manifestation of coronary lesions in patients with premature coronary heart disease. Methods Coronary angiography was done in 415 coronary heart disease (CHD) patients. Patients were devided into two groups by age. One hundred and eighty patients with premature CHD (male≤55 years-old,female≤65 years-old) were compared with 235 patients with mature CHD to illustrate the risk factors of premature CHD and the clinical features of coronary lesions. Results The percentage of female patients was higher in patients with premature CHD(35.6% vs. 22.1%, P=0.003)and so were the history of dyslipidemia (74.4% vs. 55.7%, P

Objective To investigate the effect of heparin on the apoptosis and proliferation of human myeloid leukemia cell line K562 induced by vincristine.Methods K562 cells were pretreated by heparin for 1h,then cultured with 0.05 mg/L vincristine in 37℃ 5% CO2 for 24 h.Apoptosis of KS62 cells was evaluated by Hoechst 33342 staining,flow cytometer and DNA agarose gel electrophoresis after culture for 24 hours.The effect of heparin on KS62 cell proliferation and toxicitv was determined by Trypan blue staining and MTT assay.Results In the apeptosis induced group,the apeptosis rate was 40.10% dected by Hoechst 33342 fluorescence staining.The hepafin in different concentrations was found to be able to inhibit the apoptosis of K562 cells triggered by vincristine and the apoptosis rate was 32.47%,29.7%,25.5%,19.53% in the heparin groups of 25,50,100,200 U/ml,respectively.The apeptosis rate was significantly lower in the apeptosis induced group than in the heparin groups of 25,50,100,200 U/ml(P＜0.05).The typical DNA ladder could be found in the apoptosis-induced group,and the DNA ladder gradually disappeared along with the increase of heparin(5～200 U/ml).The sub-G1 peak of K562 cells could be found in the induced group by FACS and the apoptosis rate was 21.61%.In the heparin groups of 25,50,100,200 U/ml,the sub-G1 Peak of K562 cells gradually dropped and the apoptosis rate was 13.64%,11.75%,8.59%,6.03%(P＜0.05),respectively.After K562 cells were incubated with different hepafin concentrations(5～200 U/ml)for 24 hours,there was no difference compared with the normal control group in both the total live cell numbers and the cell proliferation rate measured by trypan blue staining and MTT assay(P＞0.05).Conclusion The results suggested that heparin had no influence on KS62 cell toxicity and proliferation,but may inhibit the apoptosis of KS62 cells induced by vincristine.

OBJECTIVE:To investigate the effects of Melilotus extract tablet on postoperative therapeutic efficacy of chronic sinusitis endoscopic surgery and the recovery of nasal mucosa. METHODS:The clinical data of 100 patients undergoing chronic si-nusitis functional endoscopic surgery in our hospital from May 2015 to Oct. 2016 were analyzed retrospectively and they were divid-ed into control group and observation group according to postoperative treatment,with 50 cases in each group. Two groups received anti-inflammatory,anti-histamine and hemostasis therapy. The control group received Eucalyptol,linonene and pinene enteric soft capsules 0.3 g,tid;observation group was additionally given Melilotus extract tablet 1.2 g,tid,for 6 weeks,on the basis of con-trol group. VAS and Lund-Kennedy endoscopic score were compared between 2 groups before and after treatment. Clinical effica-cies and the occurrence of ADR were also compared between 2 groups. RESULTS:there was no statistical significance in VAS score and its total score,Lund-Kennedy endoscopic score and its total score between 2 groups before treatment (P>0.05). After treatment,VAS score and its total score,Lund-Kennedy endoscopic score and its total score of 2 groups were significantly de-creased,and the observation group was significantly lower than the control group,with statistical significance(P<0.05). The cure rate of observation group was 72.0%,which was significantly higher than 44.0% of control group,with statistical significance (P<0.05). There was no significant difference in the incidence of adverse reactions between the 2 groups (P>0.05). CONCLU-SIONS:Melilotus extract tablet helps to improve clinical efficacy and the recovery of nasal mucosa in patients with chronic sinus-itis after endoscopic surgery,with good safety.

Objective:To investigate the association between the apolipoprotein A5(APOA5) -1131T/C polymorphism and premature coronary heart disease in northern Chinese Han population. Methods: Using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and polyacrylamide gel electrophoresis (PAGE), we analyzed the genotype and allele distribution in 140 patients with premature coronary heart disease diagnosed by coronary angiography and 156 healthy controls. The levels of serum lipid profiles were also studied by biochemical methods. Results: The allele frequency of APOA5-1131T/C polymorphism in the premature coronary heart disease group was significantly higher (43.2% vs. 33.0%, P=0.011) than that in the control group. Compared with TT homozygotes, CC homozygotes exhibited a 2.809-fold (95% CI 1.331-5.927) increased risk of developing premature coronary heart disease. Logistic regression analysis found that this correlation was independent of sex, age, body mass index (BMI), smoking history as well as serum total cholesterol(TC), high density lipoprotein cholesterol (HDL-C) and low density lipoprotein cholesterol (LDL-C) levels; In premature coronary heart disease group, the triglyceride(TG) level in CC homozygotes was significantly higher than those in TC heterozygotes or TT homozygotes. Conclusion: The APOA5-1131T/C polymorphism has influence on serum TG level, and the APOA5-1131C allele is associated with the development of premature coronary heart disease in northern Chinese Han population.
