OBJECTIVE To analyze the values of drug-resistant Pseudomonas aeruginosa pneumonia in the older patients using thymosin ?1 combined with Sulperazone.METHODS The thirty five older patients with drug-resistant P.aeruginosa pneumonia were divided into two groups,one group was treated with thymosin ?1 combined with Sulperazone,the other group was treated with Sulperazone alone.We observed the changes in clinical symptom of the patients,results in culture of sputum,routine blood test,C-reactive protein(C-RP),albumin,pre-albumin,and T cell subset before and after drug use.RESULTS The clinical symptoms of the patients were improved,days of disappeared drug resistance of P.aeruginosa,reconverted normally days of routine blood test,decreased concentration of CRP,albumin,and pre-albumin reconverted to normalize,increased percent of CD4+,decreased percent of CD8+,CD4+ /CD8+ were more prominently reconverted to normalize in thymosin ?1 combined with Sulperazone treated group than in Sulperazone alone group.CONCLUSIONS Thymosin ?1 can improve immunological function,inflammation condition and protein metabolism.Its application with Sulperazone has a coordinated effect on drug-resistant P.aeruginosa pneumonia in the older patients.

OBJECTIVE:To investigate the clinical efficacy and safety of mirtazapine combined with citalopram in the treat-ment of sleep disorder in depressive patients. METHODS:One hundred and sixty-five depressive patients with sleep disorder were selected and divided into control group (82 cases) and treatment group (83 cases) according to random number table. Control group took Escitalopram oxalate tablet 10 mg,once every night,increasing to 20 mg according to disease condition;treatment group was additionally given Mirtazapine tablet 15 mg,once every night,increasing to 30 mg one week later. Both groups re-ceived treatment for consecutive 6 months. HAMD-17 and MADRS were observed in 2 groups before and after treatment,and the sleep quality of 2 groups were evaluated by PSQI before and after treatment;the sleep structure was measured by using polysom-nography before and after treatment;clinical efficacies and the occurrence of ADR were compared between 2 groups. RESULTS:Before treatment,there was no statistical significance in HAMD-17,MADRS and PSQI score,sleep structure between 2 groups (P>0.05);after treatment,above scores and indexes of 2 groups were all improved significantly,and the treatment group was sig-nificantly better than the control group,with statistical significance(P<0.05). Total response rate of treatment group was 97.47%, which was significantly higher than 78.95%of control group,with statistical significance(P<0.05). There was no statistical signif-icance in the incidence of ADR between 2 groups(P>0.05). CONCLUSIONS:Citalopram combined with mirtazapine shows sig-nificant therapeutic efficacy for sleep disorder of depressive patients,and can significantly improve sleep structure,adjust sleep cy-cle and improve sleep quality with good safety.

Objective: To study the influence of high cell incubating temperature on AMP-activated protein kinase(AMPK) activity and lipid metabolites of piglets hepatocytes in vitro.Method: Primary hepatocytes of piglets about age 55d were separated and cultured under 37 ℃(control) or 42 ℃(heat stress).The anabolic and catabolic products of [14C]-oleic acid were detected for hepatocytes and culture media at 60min,120min and 180min.There were 9 replicates per time point.Result: Heat stress activated AMPK activity and enhanced fatty acid oxidation.The production of [14C]-CO2 and [14C]-acid soluble metabolites(ASM) was higher in heat stress group than in the control.At the same time,heat stress depressed the incorporation of [14C]-oleate into phospholipids,monoglycerides,triglycerides,cholesterol and cholesteryl ester.Conclusion: Heat stress activated AMPK activity and enhanced the formation of anabolic products and depressed catabolic products in piglets hepatocytes in vitro.

Objective To evaluate the usefulness and specificity of diffusion weighted imaging (DWI) in the diagnosis of intracranial epidermoid Methods Fifteen patients with surgically proved intracranial epidermoids were evaluated with T 1 , T 2 weighted imaging, proton density weighted imaging and fast fluid attenuated inversion recovery (FLAIR) sequences followed by echo planar DWI Results DWI depicted all tumors ( n =15) as strong hyperintensity relative to CSF and brain tissues DWI was also sensitive in assessing small residual foci ( n =4) and recurrence of tumor ( n =3) Conclusion DWI is highly sensitive and specific in demonstrating epidermoids, and also in postoperatively assessing small residual foci and recurrence of tumors

A total of 152 strains of endophytic fungi were isolated from the barks of Eucommia ulmoides in three regions (Lueyang country, Zunyi country, Cili country). Based on morphological characteristics and analysis of ITS sequences, these strains were identified into 8 genera. Thereinto Phomopsis, Diaporthe and Alternaria were common genera to Eucommia barks from different sites. But the dominant genus was different: Alternaria was the dominant genus in the barks from Cili country, and Phomopsis was the dominant genus from Zunyi country, then Diaporthe was the one from Lueyang country. According to the similarity coefficient, the composition of the endophytic fungi was distinctly different between the barks from three sites. The diversity and species richness in Lueyang country and Cili country were found higher than those in Zunyi country. The evenness of endophytic fungi was 0.936 5 in Lueyang county, which was higher than 0.737 1 or 0.641 0 in Cili county or Zunyi county, respectively. After phylogenic analysis and calculating the genetic distances of typical strains belong to Phomopsis and its perfect stage--Diaporthe, there was very high genetic diversity in the two genera from our study. In conclusion, the community structure and diversity of endophytic fungi were significant different in Eucommia barks from the three habitats.

The fermentation of Bacillus cereus DLSL-2 was investigated through single-factor test. The optimized fermentation conditions are: temperature 30℃,initial pH 7.0,250 r/min. Uniform design was used in shaking flask to optimize the fermentation medium of bacillus cereus . The most suitable medium was identified as follows:4.88% defated soybean power ,1.45% maize starch, 0.106% K 2HPO 4, 1.78% yeasts extract, 5.6% inoculum. the optimized medium allowed the B.cereus biomass concentration to be increased from 3.2?109 cfu/mL to 7.1?109 cfu/mL.

OBJECTIVETo investigate the prognostic factors for non-small cell lung cancer(NSCLC)in patients under 40 years of age.

METHODSThe clinicopathological data of 148 young patients with NSCLC were retrospectively analyzed. Kaplan-Meier and Cox regression analyses were used to analyze the relationship between prognostic factors and survival time.

RESULTSThe patients were followed-up for 6 - 148 months, and the follow-up rate was 100%. In the whole group, 122 patients died and 26 cases were surviving. The 1-, 3- and 5-year survival rates were 54.7%, 10.4% and 5.6%, respectively. The median survival time (MST) was 14.7 months. Kaplan-Meier analysis showed that Karnofsky performance status (KPS), clinical stage, treatment modality and serum CEA were related with prognosis (P < 0.05). Multivariate analysis indicated that KPS, clinical stage, treatment modality and serum CEA were independent prognostic factors (P < 0.05).

CONCLUSIONSKPS, CEA, clinical stage and treatment modalities are independent prognostic factors in young NSCLC patients.

Objective To investigate the effects of the interaction between human hepatoma cells and hepatic stellate cells on their growth state,and study its role of interaction on the progression of hepatocellular carcinoma.Methods Human hepatoma cell line HepG2 and hepatic stellate cell line hepatic stallate cells (HSC)-T6 were used and the methods including methyl thiazolyl tetrazolium (MTT) assay,flow cytometry (FCM) analysis,immunohistochemistry,and electron microscopy were employed in this experiment.The effects of conditioned medium (CM) of HepG2 on the activation and proliferation of HSC were explored.The effects of activated HSC CM on HepG2 proliferation were investigated.The uhrastructural changes of the two co-cultured cells were observed.Results MTT assay result showed that HepG2/HSC CM could promote HSC/HepG2 proliferation.FCM result demonstrated that HepG2/HSC CM could influence the cell cycle distribution in HSC/HepG2.Immunohistochemistry exhibited that after the treatment of HepG2/HSC CM,the expression ofα-smooth muscle actin (α-SMA) in HSC and proliferating cell nuclear antigen (PCNA) in HepG2 were increased.When HepG2 and HSC were co-cultured,the ultrastructure of HSC displayed an activated feature.Conclusions HepG2 cells can induce the activation and proliferation of HSC,and the activated HSC can also stimulate the proliferation of HepG2.Interaction between hepatoma cells and hepatic stellate cells may play an important role in the progression of hepatocellular carcinoma.

Objective To study the mutagenic action of antiepileptic drugs(AEDs), and find an effective way to prevent the mutagenesis induced by AEDs,by observing the effects of AEDs on serum folic acid(FA) level and sister chromatid exchange (SCE) frequency in epileptic children.Methods Ninty epileptic children were divided into different groups on the basis of the different drugs they had taken, then detected the two indexes at different time points.Results The serum FA level and SCE frequency of the patients significantly decreased and increased after they took carbamazepine (CBZ) and valproic acid (VPA)respectively. The two indexes went back respectively when supplied with FA.Conclusions Both CBZ and VPA possess mutagenic action, yet nitrazepam does not.FA may help repair the chromosome damage and reduce the mutagenesis effects.
