In order to increase the production of insecticidal crystal proteins Cry1 and Cry2, firstly, Plack-ett-Burman design was applied to evaluate the effectiveness of the related nutrition factors; it was found that the soybean powder and MnSO4?H2O were significant factors for Cry1 production, but the yield of Cry2 wasn’t effected remarkably in such medium. Then the steepest ascent experiment was adopted to approach the optimal region of the medium composition. Lastly, the optimal concentration of the soybean powder and MnSO4?H2O was 11.5 and 0.02 g/L, obtained by response surface methodology (RSM). The final yields of Cry1 and Cry2 was 0.32 mg/mL and 0.11 mg/mL, increasing twice more than that in the medium optimized before. The median lethal concentration (LC50) of optimal medium was 1.09 ?L/mL. The toxicity to Heli-coverpa armigera was significantly enhanced than the old one.

Objective: To understand the survival status and influencing factors of HIV/AIDS patients with highly active antiretroviral therapy ( HAART ) among drug users in Yili Prefecture, Xinjiang from 2005 to 2019, so as to provide references for reducing AIDS mortality. Methods : The demographic information, clinical stage, baseline CD4+T lymphocyte ( CD4 ) level and treatment status of HIV/AIDS patients with HAART in Yili Prefecture from 2005 to 2019 were collected through AIDS Antiretroviral Therapy Information System. The survival rate was calculated by the life table method. The influencing factors for survival time were analyzed by Cox proportional hazard regression model. Results: Totally 1 935 patients were recruited, the median age receiving HAART was 37 years old and the median CD4 counts was 293/μL. The cumulative survival rates at 1, 5, 7 and 10 years were 97%, 78%, 73%, and 66%, respectively. The multivariate Cox proportional hazards regression analysis showed that the patients with body mass index of 18.5-<28.0 kg/m2 ( HR: 0.391-0.656, 95%CI: 0.234-0.958 ), baseline CD4>200/μL ( HR: 0.354-0.667, 95%CI: 0.232-0.841 ) , or missed medication in the last 7 days ( HR=0.009, 95%CI: 0.001-0.061 ) had lower risk of death; the patients with WHO clinical stage of Ⅱ-Ⅳ ( HR: 1.479-2.311, 95%CI: 1.004-3.288 ) or treatment delay ≥1 years ( HR: 1.287-1.388, 95%CI: 1.029-1.826 ) had higher risk of death. Conclusions The 5-year cumulative survival rate of HIV/AIDS patients with HAART in Yili Prefecture is 78%. Body mass index, baseline CD4 level, WHO clinical stage, treatment delay and missed medication in last 7 days were the influencing factors for survival time.

Leaves of Chrysanthemum morifolium were potential medicinal resource. The present study aims to estimate the main bioactive components: total flavonoids (TF), galuteolin (GA), quercitrin (QU), chlorogenic acid (CA) and 3 ,5-O-caffeoylquinic acid ( CQ), which were considered to be the main effective components, in leaves of C. morfolium cultivars in China. The TF content was estimated hy UV-VIS spectrophotometry, while GA, QU, CA, and CQ were quantitatively determined by HPLC. The highest TF content (7. 13% w/w) was found in cultivar Wan Cong (Shexian county). Cultivar Da Bo ( Bozhou county) had the highest GA content (33. 45 mg - g-1); Cultivar Hong Xin (Sheyang county) contained the highest QU content (29.25 mg · g(-1)); Cultivar Chang Ban (Sheyang county) had the highest CA content (13.14 mg ·(-1)). The maximum CQ content (7.35 mg · g(-1)) was observed in culti- r Da Yang ( Tongxiang county). Different cultivars of C. morfolium had significant difference in components, but the leaf and capitulum of C. morifolium. were found to possess similar chemical compositions. The high content of bioactive components in several cultivars suggested the potential utilization of C. morifolium leaves.

OBJECTIVETo study the effect of Aidi Injection (艾迪注射液,ADI) applied in the bronchial artery, applied in the bronchial artery infused (BAI) neo-adjuvant chemotherapy for stage III A non-small cell lung cancer (NSCLC) before surgical operation.

METHODSThe 60 patients with NSCLC stage III A underwent two courses BAI chemotherapy before tumor incision were assigned to two groups, the treatment and the control groups, using a random number table, 30 in each group. ADI (100 mL) was given to the patients in the treatment group by adding into 500 mL of 5% glucose injection for intravenous dripping once daily, starting from 3 days before each course of chemotherapy, and it lasted for 14 successive days, so a total of 28 days of administration was completed. The therapeutic effectiveness and the adverse reaction that occurred were observed, and the levels of T-lymphocyte subsets, natural killer cell activity, and interleukin-2 in peripheral blood were measured before and after the treatment.

RESULTSThe effective rate in the treatment group was higher than that in the control group (70.0% vs. 56.7%, P<0.05). Moreover, as compared with the control group, the adverse reaction that occurred in the treatment group was less and mild, especially in terms of bone marrow suppression and liver function damage (P<0.05). Cellular immune function was suppressed in NSCLC patients, but after treatment, it ameliorated significantly in the treatment group, showing significant difference as compared with that in the control group (P<0.05).

CONCLUSIONADI was an ideal auxiliary drug for the patients in stage III A NSCLC received BAI neo-chemotherapy before surgical operation; it could enhance the effectiveness of chemotherapy, ameliorate the adverse reaction and elevate patients' cellular immune function; therefore, it is worthy for spreading in clinical practice.

OBJECTIVETo evaluate the impact of radiofrequency catheter ablation on left atrial (LA) size and function in patients with paroxysmal atrial fibrillation (PAF) and whether there is any difference between segmental pulmonary vein ostial isolation (SPVI) and circumferential pulmonary vein ablation (CPVA).

METHODSSixty-six patients with highly symptomatic atrial fibrillation were assigned to undergo either SPVI or CPVA. Transthorax echocardiography was performed before, 1 day, 1 months and 3 months after the procedure. LA dimension, LA area, late diastolic peak velocity of mitral valve inflow (A) and peak atrial systolic mitral annulus velocity (A') were recorded.

RESULTSOf 66 consecutive patients with symptomatic PAF, 30 patients underwent SPVI and 36 underwent CPVA. After a mean follow-up of (315 +/- 153) days, 21 patients (70%) after SPVI and 28 patients (75%) after CPVA were free of atrial tachyarrhythmia. As compared with the baseline, LA area decreased at 1-month after ablation in SPVI group and at 3-month in CPVA group. LA dimension decreased also in SPVI group, but did not in CPVA group. A velocity and A' velocity declined remarkably 1 day after CPVA, and restored 3 months later. The former went back to the level of baseline, and the latter exceeded it apparently. In SPVI group, A velocity increased at 1-month, and maintained in 3-month after ablation. A' velocity increased at 3-month after ablation. No reduction of A velocity or A' velocity was found after SPVI.

CONCLUSIONSThis study demonstrated a decrease in LA area and an improvement in LA systolic function 3 months after ablation for PAF. The LA damage by CPVA was more than that by SPVI, which was characterized by the reduction of LA function 1 day after procedure and the delayed improvement of LA size and functional parameters.

OBJECTIVETo investigate the changes of gene expression file in transitional cell carcinoma of bladder after hepatocyte cell adhesion molecule(hepaCAM) overexpression.

METHODSAffymetrix Human Genome U133 Plus 2.0 Array was used to investigate the changes of gene expression profile between adenovirus-green fluorescent protein(GFP) -hepaCAM group and GFP group in transitional cell carcinoma of bladder EJ cells.Significant Analysis of Microarray(SAM) was used to screen the differentially expressed genes, DAVID software was used to conduct gene ontology analysis and wikiPathway analysis based on the differentially expressed genes. Reverse transcription-polymerase chain reaction and Western blot were applied to verify microarray data.

RESULTSCompared with the GFP group, a total of 2469 genes were up-regulated or down-regulated by more than 2 times in the GFP-hepaCAM group. Among these genes, 1602 genes were up-regulated and 867 were down-regulated.Most of the differentially expressed genes were involved in the function of cell proliferation and cell cycle regulation. The mRNA expressions of nibrin, liver kinase B1, and cyclin D1 detected by reverse transcription-polymerase chain reaction in three different bladder cancer cell lines were consistent with the microarray data.The protein expressions of nibrin and liver kinase B1 in these three cell lines measured by Western blot were consistent with the mRNA expression.

CONCLUSIONSHepaCAM can alter the gene expression profile of bladder cancer EJ cells. The well-known anti-tumor effect of hepaCAM may be mediated by regulating the gene expression via multiple pathways.

BACKGROUNDThe relationship between monosymptomatic resting tremor (mRT) and Parkinson's disease (PD) remains controversial. In this study, we aimed to assess the function of presynaptic dopaminergic neurons in patients with mRT by dopamine transporter positron emission tomography (DAT-PET) and to evaluate the utility of clinical features or electrophysiological studies in differential diagnosis.

METHODSThirty-three consecutive patients with mRT were enrolled prospectively. The Unified Parkinson's Disease Rating Scale and electromyography were tested before DAT-PET. Striatal asymmetry index (SAI) was calculated, and a normal DAT-PET was defined as a SAI of <15%. Scans without evidence of dopaminergic deficits (SWEDDs) were diagnosed in patients with a subsequent normal DAT-PET and structural magnetic resonance imaging.

RESULTSTwenty-eight mRT patients with a significant reduction in uptake of DAT binding in the striatum were diagnosed with PD, while the remained 5 with a normal DAT-PET scan were SWEDDs. As for UPRDS, the dressing and hygiene score, walking in motor experiences of daily living (Part II) and motor examination (Part III) were significant different between two groups (P < 0.05 and P < 0.01, respectively). Bilateral tremor was more frequent in the SWEDDs group (P < 0.05). The frequency of resting tremor and the amplitude of postural tremor tend to be higher in the SWEDDs group (P = 0.08 and P = 0.05, respectively).

CONCLUSIONSmRT is heterogeneous in presynaptic nigrostriatal dopaminergic degeneration, which can be determined by DAT-PET brain imaging. Clinical and electrophysiological features may provide clues to distinguish PD from SWEDDs.
