Objective To understand the implementation status and effect of prevention and control of malaria in Libo Coun?ty so as to provide the evidence for improving the malaria elimination working. Methods The data about malaria from the county CDC and county hospital were collected and 16 villages from 8 townships were randomly sampled and 10 villagers of each village were investigated. Other information about the prevention and control of malaria was also investigated. Results The inci?dence of malaria was decreasing annually from 5.75 per 10 000 in 2008 to zero in 2012. The malaria monitoring could be well conducted in the county and township levels. The infection source could be controlled in time. The utilization rate of anti?mosqui?to facilities in the residents was 93.25%and the awareness rate of knowledge about malaria prevention and control was 40.13%. Conclusions The implementation and effect of prevention and control of malaria are satisfactory in Libo County but the medi?um control is limited and the active protection consciousness of the residents is not strong. Therefore the task of malaria elimina?tion is still very arduous.

Aim To investigate the antagonistic action o f total saponins of panaxnotoginseng(PNS) on cardiac hypertrophy and its nervous mechanism.Methods (1)cardiac hypertrophy of rats due to pressure overload was induced by constricting of abdominal aorta. There were five groups in the experiments. The rats in Group A(control group)were sham operated . Group B was aorta-constricted group.The rats in Group C,D,E were given ip PNS 50,100,150 mg?kg?d -1 for three weeks respectively. Three weeks later, We measured the heart-weight(HW),left ventricular weight(LVW), the ratio of HW/BW,LVW/BW (LVI) and the cardiomyocyte diameters(MD) after dyeing by HE color.(2)The effects of PNS on the fast excitatory postsynaptic potential(f-EPSP),membrane depolarization induced by application of acetylcholine (ACh),membrane potential and membrane resistance of the isolated Stellate ganglion(SG)of the rats were investigated by means of intracellular recording techniques. Results (1)HW/BW, LVI and MD of Group E were significantly lower than that of Group B(P0.05).(2)At the concentration of 0.10 ～0.16 g?L -1, PNS reversibly depressed the amplitude of f-EPSP, but the ACh depolarization,membrane potential and membrane resistance were not significantly altered by PNS. Conclusion PNS can prevent cardiac hypertrophy due to pressure overload in rats and this action may underline its inhibitory action on presyn aptic effect of regulating calcium influx.

BACKGROUND: Panax notoginseng saponins (PNS) could significantly improve the learning and memory ability of rats, but its influence to peripheral nervous system still needs further investigation.OBJECTIVE: To observe the effects of PNS on the fast-excitatory postsynaptic potential (f-EPSP) in stellate ganglion (SG) of rats.DESIGN: Observation and controlled trial.SETTING: Pharmacological Laboratory of Guangxi Medical University.MATERIALS: The experiment was carried out at the Pharmacological Laboratory of the Experimental Center of Guangxi Medical University from January 2005 to February 2006. Thirty healthy male SD rats of clean grade and (220±20) g, provided by the Experimental Animal Center of Guangxi Medical University; SEN-7203 digital three track strip stimulator, microelectrode amplifier (MEZ8301, Japan NIHON KOHDEN COMPANY); glass microelectrode puller, and microelectrode manipulator, both the products of Narishige Company, Japan; PNS, provided by Kunming Jacobson Pharmaceutical Co., Ltd, and acetylchloride chline (Ach), the product of Sigma, U.S.A.METHODS: After the animals were executed acutely, their chest wall was opened to isolate SG rapidly under microscope, which was transferred to the perfusion chamber, and fixed with wire needles after peeling the connective tissue membrane. The ganglia were perfused continuously with the mixture of volume fraction 0.95 O2 and 0.05 CO2 plus Krebs solution with pH (7.4±0.05). Meanwhile, 0.08-0.16 g/L PNS was employed to perfuse and culture SG.①The glass microelectrode filled with 3 mmol/L KCI was used to puncture the isolated SG and record the amplitude and duration of depolarizing reaction of postsynaptic membrane.②PNS with the maximum concentration of 0.16 g/L, which could inhibit the f-EPSPs, was perfused to observe the effect of PNS on the amplitude and duration of depolarizing reaction of postsynaptic membrane induced by exogenous Ach (1 mmol/L, 1 minute).③PNS with the maximum concentration of 0.16 g/L, which could inhibit the f-EPSPs, was perfused to observe the effect of PNS on membrane resistance and membrane potential.MAIN OUTCOME MEASURES:①Amplitude of depolarizing reaction of postsynaptic membrane; ②Effect of PNS on the amplitude and duration of depolarizing reaction of postsynaptic membrane induced by exogenous Ach, and membrane resistance and membrane potential.RESULTS: Thirty rats were involved in the result analysis. ①PNS ranged 0.08 to 0.16 g/L could reversibly depress the f-EPSPs amplitude of, or change the forward active potential into f-EPSP; the higher the concentration of PNS, the more obvious the inhibition was. The depression appeared in 3-10 minutes after PNS perfusion, and the effect reached the peak at 0.16 g/L; f-EPSP was decreased evidently in 3 to 4 minutes. The inhibition nearly recovered to the control level after washing the ganglia with Krebs solution for 15 to 20 minutes. ②Effect of PNS on exogenous ACh-induced depolarization: The amplitude and duration of the Ach-induced depolarization did not significantly change before and 5 minutes after 0.16 g/L PNS perfusion [before: (15.5±2.4) mV, (256.1±21.5) seconds; after: (14.3±1.9) mV, (228.6±24.5) seconds, P＞0.05].③Effects of PNS on membrane potential and membrane resistance: The mean membrane potential and membrane resistance were not significantly changed after PNS perfusion [before:-(55.5±12.1) mV, (53.9±5.1) MΩ; after: -(54.3±10.4) mV, (55.1±4.8)MΩ, P＞0.05].CONCLUSION: PNS could reversibly depress the fast-excitatory postsynaptic potential in stellate ganglion of rats by presynaptic mechanism.

Dead-in-bed syndrome (DBS) is a rare but devastating sudden death condition that mainly affects young patients with type 1 diabetes.Its mechanism is quite complicated and may involve multiple factors.Acute onset of recurrent and severe nocturnal hypoglycemia,abnormal cardiac repolarization,genetic factors,and obstructive sleep apnea may all contribute to ventricular arrhythmias and even sudden death.The future research plans include elucidating and understanding the underlying mechanisms and triggers for DBS,developing a risk stratification system,using real-time continuous glucose monitoring system to detect severe nocturnal hypoglycemia,and initiating appropriate therapeutic interventions to uhimately prevent the tragedy.
