OBJECTIVETo learn about the photosynthetic characteristics of Sarcandra glabra and provide the theoretic references for its better planting.

METHODThe photosynthetic parameters of twenty different provenances of Sarcandra glabra were determined by Li-6400 portable photosynthesis system, and the data was analyzed by Excel and SAS software.

RESULTThe results showed that the light saturation point of different Provenances of S. glabra were almost about 800 micromol x m(-2) x s(-1), while the light compensation point of them were from 14.70 micromol x m(-2) x s(-1) to 48.68 micromol x m(-2) x s(-1). The curve of net photosynthetic rate had two peaks on sunny day, the first one was in the morning and the other one was in the afternoon. The photosynthetic "noon- break" of S. glabra appeared between 11:00-13:00, when the net photosynthetic rate goes down sharply. Intercellular CO2 concentration (C(i)), CO2 concentration (CO2S) and transpiration rate (T(r)) all have effect on the diurnal change of net photosynthetic rate (P(n)) of S. glabra, and the average correlation coefficient between P(n) and the parameters above were orderly as -0.89 (P < 0.01), -0.75 (P < 0.05) and 0.69 (P < 0.05);

CONCLUSIONS. glabra was a plant with characteristics of shade-tolerance, and through the way of covering, sprinkling for decreasing the surrounding temperature would be effective to reduce its "noon-break" time and increas its efficiency of photosynthesis.

Hydroxyapatite nanoparticles were prepared in low Ca/P ratio by a kind of electrodeposition-hydrothermal process. The suspension of nanoparticles was cultured with SGC-7901 cells; metabolically active cells were evaluated by MTT analysis. Cells grew well and the nanoparticles in the concentration range of 10-100 microg/ml had no adverse effect on the cell viability. The results show that the nanoparticles have excellent biocompatibility with cells. Agrose gel electrophoresis analysis demonstrated that the nanoparticles had the potential to adsorb EGFP-N1 at the pH ranging between 2 to 7. Nanoparticle-DNA complex could transfer EGFP-N1 into the SGC-7901 cells, and the confocal microscopy analysis revealed that the cells with green fluorescence showed the efficiency of nanoparticle uptake to be about 80% of the efficiency of the Lipofectmine TM 2 000 uptake. In vivo, nanoparticles and DNA-nanoparticle complex were injected into mice respectively via tail-vein, and the mice grew well in two weeks. The liver, kidney, and brain of the mice were sampled and detected with electron microscopy, and all of these exhibited biodistribution of nanoparticles. This study demonstrates that Hydroxyapatite nanoparticles could be used as gene carriers.

Objective To investigate the effects of metformin and exaliplatin on proliferation and apoptosis of gastric cancer cell line SGC-7901. The antitumor effects of metformin combined with exaliplatin on gastric cancer cell line SGC-7901 were compared. Methods SGC-7901 cells were cultured in vitro. The proliferation inhibition rate of cancer cell after treatment with various concentrations of metformin(5.0,10.0,15.0 mmol/L)、exaliplatin(2.5,5.0,10.0 μmol/L)or 15.0 mmol/L metformin combined with 10.0 μmol/L exaliplatin was analyzed via MTT colorimetric assay at 24,48,72 h.After 24 h, the SGC-7901 cell apoptosis was detected by flow cytometry, and the relative activity of caspase-3 and bax was detected by western blot. Results The co-administration of metformin and exaliplatin or single agent treatment could increase the proliferation inhibition rates of SGC-7901 cell in a time-and dose-dependent manner, while there was a significant higher proliferation inhibition rate in co-administration versus single-agent treatment (P < 0.05). The apoptosis rate induced by 15.0 mmol/L metformin and 10.0 μmol/L exaliplatin and combined treatment was (16.0 ± 2.1)%, (19.0 ± 2.7)%, (29.0 ± 3.5)%, higher than that in blank control group (10.0 ± 1.1)%, and there was significant difference (P <0.05). Both of metformin and exaliplatin could increase caspase-3 and Bax activity.Caspase-3 and Bax activity in the combination of metformin and exaliplatin was significantly higher than that of metformin group and exaliplatin group (P < 0.05). Conclusions Metformin combined with exaliplatin has synergistic effect in inhibiting the growth and inducing apoptosis of gastric cancer cell line SGC-7901.Enhancing caspase-3 and Bax expression may be the related mechanism

OBJECTIVETo explore the relationship between ventilator efficiency of cardiopulmonary exercising test (the slope of the relation between ventilation and carbon dioxide production, VE/VCO(2)slope) and systolic pulmonary artery pressure (sPAP) measured by echocardiography in patients with chronic heart failure (HF).

METHODSData from 86 HF patients who were treated in Fuwai Hospital between December 2012 and July 2014 and performed the symptom limited maximal cardiopulmonary exercise test (CPET) and echocardiography were retrospectively analyzed.H F patients were divided into 3 groups (mild, moderate and severe) according to the maximum oxygenconsumption (peakVO(2)).

RESULTSThere is a significant linear correlation between VE/VCO(2)slope and sPAP (r=0.260, P=0.016). Using VE/VCO(2)slope>34.2 as a cutoff value to predict patients with sPAP>50 mmHg (1 mmHg=0.133 kPa) yielded a sensitivity of 70.0% and a specificity of 64.3%. The degree of the linear correlation between VE/VCO(2)slope and sPAP is stronger in mild HF patients (peakVO(2)>14 ml·kg(-1)·min(-1), r=0.686, P<0.001). Using VE/VCO(2) slope>34.2 as a cutoff value to predict sPAP>50 mmHg in mild HF patients, the sensitivity is 71.4% and the specificity is 93.8%.

CONCLUSIONThere is a significant linear correlation between VE/VCO(2)slope and sPAP in HF patients. VE/VCO(2)slope>34.2 is linked with a high possibility of sPAP>50 mmHg in HF patients, especially for patients with mild HF. Invasive hemodynamic examination and impact of special therapy are warranted in future studies to veryfy present results.

The purpose of the study is to construct recombinant goat pox virus (GPV) expressing Peste des petits ruminants virus (PPRV) H protein, and to evaluate the immunization effect. Recombinant GPV containing PPRV H gene (rGPV-PPRV-H) was selected and purified by gpt and eGFP utilizing plaque purification, and the final selected recombinant GPV was proved to be purified by PCR. Immunofluorescence and Western blotting showed that the recombinant virus could express H protein of PPRV while infecting lamb testis cells. Six goats were immunized with 2 x 10(6) PFU rGPV-PPRV-H through intradermal injection, and were immunized for the second time at 28 days with the same dose recombinant virus after first immunization. Serum was collected after immunization, and was analyzed for the neutralization antibodies. 21 days after first immunization, the neutralization antibodies of GPV were 40, 80, > or = 80, > or = 80, 40, > or = 80 in turn, and neutralization antibodies of PPRV were 80, 80, 80, 80, 40, 40, 10 in turn; 14 days after second immunization, the neutralization antibodies of GPV were all > or = 80, and the neutralization antibodies of PPRV were > 80, 80, > 80, 80, 80 and 40 in turn. This study established a foundation for the industrialization of the PPRV recombinant GPV vaccine.

OBJECTIVE: To evaluate the effectiveness of laparoscopic Roux-en-Y gastric bypass (LRYGB) surgery for treatment of type 2 diabetes (TD) in patients with a body mass index (BMI) < 27.5 kg/m. METHODS: We retrospectively analyzed the data of patients who underwent LRYGB surgery from March, 2012 to June, 2018 in the General Hospital of Guangzhou Military Command and Jinshazhou Hospital of Guangzhou University of Chinese Medicine. The changes in the parameters of glucose metabolism and physical indicators of the patients in the first, second and third years after the surgery were analyzed in patients in low BMI group and high BMI group. RESULTS: All the 74 patients underwent LRYGB successfully without conversion to open surgery. One year after the surgery, fasting blood glucose (FBG), HbA1c, postprandial blood glucose, fasting insulin, HOMA-IR, fasting C-peptide, BMI, body weight and waistline were significantly improved compared with their preoperative values in low BMI group ( < 0.05). At 2 years after the operation, FBG, HbA1c, postprandial blood glucose, HOMA-IR, BMI, body weight and waistline were significantly improved compared with the preoperative values in low BMI group ( < 0.05). In the third year, FBG, HOMA-IR, fasting C-peptide, body weight and waistline were significantly improved compared with the preoperative values in low BMI group ( < 0.05). There was no significant difference in the parameters of glucose metabolism and islet function between low BMI group and high BMI group at different stages. No serious complications occurred in these patients after the surgery. CONCLUSIONS LRYGB is effective for treatment of T2D in Chinese patients with a BMI < 27.5. After the surgery, the patient show reduced waistline without significant weight loss. The long-term results of the surgery still require further investigations with a larger samples and longer follow-up.
