Objective: To evaluate the cytotoxicity and targeting ability of self-developed paclitaxel-octreotide (PTX-OCT) conjugates on A549 non-small cell lung cancer (NSCLC) cells and Calu-6 NSCLC cells. Methods: Conjugates PTX-OCT and 2PTX-OCT were synthesized by our school. Reverse transcription-polymerase chain reaction was used to detect mRNA of human somatostatin receptor subtypes (SSTRs) using specific primers. The cells were treated with different concentrations (1, 100 nmol/L and 1 ?mol/L) of paclitaxel and the conjugates for different time periods (24-72 h); we also set up a control group. MTT assay was used to evaluate the cell viability after treatment; cell cycle perturbations were determined by FAC Scan flow cytometer 24 h after treatment with 1 ?mol/L paclitaxel, PTX-OCT, and 2PTX-OCT. Results: Both A549 cell and Calu-6 cell expressed the mRNA of SSTR2 and SSTR5; no SSTR mRNA was detected in the fibroblasts. The conjugates had a similar cytotoxicity to paclitaxel; they both effectively inhibited the growth of A549 cells and Calu-6 cells in a concentration-and time-dependent manner. After 72 h treatment with 1 ?mol/L paclitaxel, PTX-OCT and 2PTX-OCT, the survival rates of A549 cells were (26.9?7.3)%, (26.6?9.2)% and (35.7?4.3)%, respectively; the survival rates of Calu-6 cells were (29.5?5.0)%, (28.2?9.7)% and (26.5?4.9)%, respectively. The survival rate A549 cells at 72 h after treatment was lower than that at 24 h after treatment(P

Objective To investigate the clinical effect of lumbar catheter drainage combined with intrathecal injection on patients with cerebrospinal fluid leakage and intracranial infection.Methods A retrospective study was conducted.One hundred and fifty-two cases with cerebrospinal fluid leakage and intracranial infection were selected as our subjects who were hospitalized in the First Hospital of Yuncheng from 2006 to 2014.The patients were divided into lumbar puncture + intrathecal group (A),lumbar (group B) and lumbar intrathecal large pool + group (group C) based on post-processing methods.A experimental data were recorded and compared in terms of the total efficiency of treatment,the therapeutically effective time,bacterial clearance and security differences.Results After treatment,the levels of white blood cells,protein,glucose and intracranial pressure were changed compared with that of before treatment in three group(P ＜ 0.01),but there was no significant difference among the three groups(P ＞ 0.05).The therapy periods in group A,group B and group C were (12.80 ± 2.25) d,(12.64 ± 2.00) d and (9.44 ± 1.50) d respectively and the difference was significant(F =25.94,P ＜ 0.05).Compared with Group C,the therapy periods in group A and B were significant different(t =2.769,2.854;P ＜ 0.05),but there was no significant difference between group A and B (t =0.119,P =0.908).The cases with success.effect was 45 (89.1％) in group A,53 (94.6％) in group B,46 (95.8％) in group C,and there was no significant difference among three groups (P ＞ 0.05).In terms of bacterial clearance rate,33 cases(68.75％) was in group A,35 cases(72.91％) in group C and 23 cases (41.07％) in group B and the effective rate in group A or C were higher than that in group B (x2 =9.478,10.63 ; P ＜ 0.05).Conclusion The methods of lumbar catheter drainage combinedwith intrathecal injection is proved with a high clinical value of therapy,effective treatment can effectively shorten the time and improve the overall treatment effect.

Objective To analyze the surgical and pathologic features of isolated ascending aortitis without evidence of rheumatologic or autoimmune diseases by comparing that of Takayasu's arteritis.Methods Consecutive 965 excised ascending aortas were reviewed and 40 cases with aortitis were selected from the pathological archives of past 20 years in Fuwai Hospital.The clinical history,laboratory and angiographic data,surgical findings,steroid therapy and followup results of these 40 cases were reviewed.Pathological parameters included the thickness of aortic wall and its various layers,inflammation activity,multinuclear giant cells,inflammatory necrosis,laminar necrosis and atheroselerosis.The t test and Chi square analysis were used to compare the means and the rates between the two groups.Results Twenty-five of 40 cases were diagnosed with isolated aortitis and its prevalencei was 2.6%(25/965),while 8 cases with Takayasu's arteritis and 7 cases with other vasculitis were confirmed.The age of isolated ascending aortitis was older than that of Takayasu's arteritis[(46±12)y vs(34±14)y,t=2.30,P>0.05] while the male/female ratio was similar in both groups(1.1 vs 1.0,t=0.01,P>0.05).Their main clinical manifestation was aortic aneurysm with a bigger aortic diameter in isolated aortitis than that in Takayasu's arteritis [(59±18)vs(46±12)mm,P>0.05].The asymptomatic cages mostly were found in isolated ascending aortitis (28%vs 0,x2=2.98,P>0.05).The erythrocyte sedimentary rate was normal in isolated aortitis but increased in Takayasu's arteritis[(15±17)mm/1 hvs[27±25)mm/1 h,U=48.50,P<0.05 ].Inflammatory edema,thickening and calcification were noted in more than half cases of both groups.but slighter thickening of aortic wall was foand in isolated ascending aortitis in contrast to the remarkable thickening in Takayasu artefifis[(2506±493)vs (3300±430)μm,t=-3.00,P<0.01].Giant cells,inflammatory necrosis,laminar necrosis and accompanied atherosclerosis were more common in isolated ascending aortitis.Aortic regurgitation was common but inflammatory invasion wege found in few aortic valves. Steroid was prescribed in 5 cases with isolated ascending aortitis and none of them was reported with complications while aortic perivalvular leakage occurred in 3 of 20 cases without steroids therapy. In the Takayasu's arteritis cases, new aneurysm of abdominal aorta was found in 1 of 3 cases with steroid therapy. Meanwhile, perivalvular leakage and subclavian artery stenosis occurred in 2 of 5 cases without steroid. Conclusion Isolated aortitis is more common than Takayasu's arteritis in ascending aortic diseases and there is some definite difference in clinical and pathological aspects between these two diseases. Since the effect of steroid therapy is uncertain and in order to avoid overtreatment, we suggest that steroid should not be given to cases with isolated ascending aortitis after surgery and clinical and angiographic follow-up should be emphasized.

Objective To investigate the toxicities and inhibitory effects of three kinds of kegin-type novel heteropoly compounds which were synthesised by molecular assembly interactions on influnenza A virus(H1N1) in vitro.Methods The toxicities and anti-influnenza virus activities were tested by methods of CPE-MTT and chick embryos culture.Results TC_(50) in MDCK cells and LD_(50) in chick embryos of three kinds of kegin-type novel heteropoly compounds were higher than those of amantadine.TI in MDCK cells and chick embryos were both higher than that of amantadine. Conclusion The three kinds of kegin-type novel heteropoly compounds have lower toxicities and higher anti-virus effects on influnenza A virus(H1N1) than amantadine.Through chemic modifications,the toxicity of amantadine can be decreased and the activity of amantadine can be increased.

OBJECTIVE:To study the effect of alcohol extract of Toddalia asiatica on the inflammation-associated cytokines of model rats with adjuvant arthritis(AA). METHODS:70 SD rats were randomly divided into a normal control group,a model con-trol group,a positive control chemical medicine group(Leflunomide tablets,0.012 g/kg),a positive control TCM group(Tripter-ygium glycosides tablets,0.012 g/kg)and the groups of low,medium and high-dose [1,4,6 g(crude drug)/kg] alcohol extract of T. asiatica,with 10 rats in each group. The rats in all groups except for the normal control group were given complete Freund’s complete adjuvant id for the establishment of AA models. At the same time,the rats in the drug administration groups were given corresponding drugs ig,while those in the normal control group and the model control group were given isometric normal saline ig,twice a day,for 28 consecutive days. The degree of toe swelling,arthritis index and the levels of interleukin(IL)-1β,IL-6, IL-10,tumor necrosis factor α(TNF-α)and prostaglandin E2(PGE2)in serum and synovial membranes of all groups of rats were determined. RESULTS:Compared to the normal control group,the model control group demonstrated higher degree of primary and secondary toe swelling,arthritis index and levels of IL-1β,IL-6,TNF-αand PGE2 in serum and joint synovial membrane,and low-er level of IL-10 therein(P<0.01). Compared to the model control group,all the above-mentioned indexes of the rats in drug ad-ministration groups significantly improved(P<0.05 or P<0.01). CONCLUSIONS:The alcohol extract of T. asiatica. has a preven-tive and therapeutic effect on the model rats with AA by regulating the expression of anti-inflammatory and proinflammatory cyto-kines in serum and synovial membrane.

Clinical data of 23 patients with T2a bladder cancer admitted from March 2008 to August 2013 were retrospectively analyzed.Among 23 patients,11 cases were treated with transurethral resection (TURBT) plus arterial catheterization chemotherapy (study group) and 12 cases were treated with radical cystectomy (control group).The overall survival time and recurrence free survival time of two groups were compared.Patients in study group were followed up for 20-68 months,recurrence occurred in 5 cases (5/11),including 4 cases of invasive recurrence;patients in control group were followed up for 2 ～86 months,1 case had superficial recurrent and underwent TURBT,2 cases dead due to bladder tumor.During the course of chemotherapy,the main adverse effects were digestive reaction (7/11),fever (4/11),bone marrow suppression (2/11),symptomatic treatment was given,which was tolerated.There were no significant differences in overall survival time and recurrence free survival time between two groups (P ＞ 0.05).The quality of life of study group was better than that of control group (P ＜ 0.05).It is suggested that the arterial interventional chemotherapy combined with transurethral resection for T2a stage invasive bladder cancer has a certain curative effect with the advantage of preservation of bladder function and higher quality of life.

The psychiatric problem has become a global public health issue. The model of mental health service advocate that“Treatment of disease occurred in the hospital, but rehabilitation and management in the community”. This brings great challenge to the community health service center. By comparing the domestic and foreign mental health service system, this paper discusses the necessity of carrying out the standardized training of general practitioners in psychiatry and psychology.
