Objective To investigate the effect of exogenous orexinA on the pyramid neurons and interneurons in the prefrontal cortex prelimbic(PL)area.Methods The pyramid neurons and interneurons in PL area of Kunming mice were selected from prefrontal cortex slices by infrared visual patch clamp technique.The morphology and electrophysiological features of the pyramid neurons and interneurons were observed.The effect of exogenous orexinA at a concentration of 400 nmol/L on these cells was studied using the whole cell configuration.Results The pyramid neurons were large,pyramidal in cell body with clear apical dendrites extending vertically and several basal dendrites radiating.The interneurons were comparatively smaller and had several processes from cell body.In current clamp mode,all 54 pyramid neurons having been recorded showed frequency adaption,and the 15 recorded interneurons discharged rapidly and had no frequency adaption.While in vol-tage clamp mode,36 pyramid neurons were regarded as Ih(+)pyramid neurons for recorded hyperpolariztion-activated cation current,and the left 18 and 15 interneurons were Ih(-).Exogenous orexinA had a total reaction rate of 51.9% on 54 recorded pyramid neurons under current clamp,and a rate of 66.7% on 36 Ih(+)pyramid neurons and of 22.2% on the Ih(-)pyramid neurons under voltage clamp.All 15 recorded interneurons had no reaction to exogenous orexinA under either mode.Conclusion OrexinA plays excitatory effect on pyramid neurons in the prefrontal cortex PL area,and this effect is much more noticeable in pyramid neurons with Ih currents.

Objective The cardiac synchronization therapy (CRT) was proven to have good treatment for the cardiac conduction disorders patients with serious heart failure. But many disadvantages were gradually be noticed, such as difficulty of sinus electrode implantation, coronary sinus injury and bleeding, still one third CRT cases remain unchanged cardiac function.Recently the epicardial lead CRT therapy by the cardiac surgeons appears promising to provide better clinic resynchronization.The aim of this research is to explore the clinical value of surgical epicardial lead CRT for the cardiomyopathy heart failure with micro-invasive thoracoscopy techniques. Methods During April 2007 to Sep 2009 eleven patients were diagnosed as advanced heart failure with cardiac dysynchronization proven by the ECG and tissue Doppler echo examination. The dysynchronization parameters of tissue Doppler echo includes left ventricle maximize delay time , the left dysynchronization index (Ts-SD), the inter-ventricle mechanical delay time (IVMD), left ventricle end-dilation diameters (LVEDD) and the left ventricle ejection fraction (LVEF). All the patients got the consent agreement before the surgery. In the hybrid operation room the right atrial and ventricle endocardial electrodes were placed firs guided by X ray under the general anesthesia and double lumnen incubation. Then the thoracoscope techniques were used to explore the left ventricle lateral wall. The right atrial and ventricle electrodes were connected into the three chamber pacemaker. The Tissue Doppler Echo TEE technique was used to check which part of the left ventricle lateral wall is suitable for the idea CRT therapy. Usually the latest activated part of the left ventricle wall is the goal place. Then the epicardial electrode was fixed with 4-0 prolene suture at the idea place. All the cases were performed by the same surgeons group in the same medical center. The resynchronization features were examined after surgery and during the follow up. Results The endocardial and epicardial electrodes were implanted successfully without any serious complication. All patients were weaned and discharged without any adverse cardiac episodes. There is no mortality during the follow up period. All the patients received the β-blokers, diuretics, ACEI/ARB and other traditional medicine for the heart failure.The Tissue Doppler showed the E peak wave separated form the A peak which means the good resynchronization between the atrium and the ventricle. After surgery during the follow up the left ventricle maximize delay time decreased from (393.4 ±40.2 ) ms to ( 102.1 ± 34.6) ms, the left dysynchronization index (Ts-SD) decreased from (145.2±29.3)ms to(51.0±21.4) ms, the inter-ventricle mechanical delay time (IVMD) decreased from (59.1 ±23.4) ms to (31.2 ± 11.5 ) ms, left ventricle end-dilation diameters increased from (73.1 ± 13.4) mm to (63.2 ± 6.7) mn and the left ventricle ejection fraction increased from 0.32 ±0.04 to 0.41 ±0.07. Conclusion The micro-invasive surgical synchronization therapy could get good CRT result for the cardiomyopathy heart failure patients. Some patients traditionally in the waiting list for the heart transplant could be considered for the CRT therapy candidates.

Objective To analyze the association of hyperuricemia with incidence of carotid plaque in general population and furthermore to explore the predictive value of serum uric acid in the early prevention of atherusclerotic disease. Methods The participants were selected from a part of Chinese Multiprovincial Cohort Study (CMCS). Two investigations on cardiovascular risk factors and two on carotid ultrasound detection were carried out in 2002 and 2007, respectively. Results (1) The standard prevalence of hyperurieemia on baseline was 5.4%, being 7.7% in male and 3.9% in female. (2) The standard incidence of carotid plaque was 45.3%, being 51.7% in male and 42. 7% in female. It was shown that the incidence of plaque in the bulb of common carotid arteries was the highest. (3) After adjusting for age, smoking, high triglyceride, high cholesterol, hypertension, diabetes, overweight and obesity,hyperurieemia in female was an independent risk factor associated with 5-year incidence of formation plaque in the bulb of common carotid; the odds ratio (OR) was 3.56 (P = 0.02, 95% CI = 1.21-10. 41).Conclusion Hyperuricemia in female was an independent risk factor associated with 5-year incidence of plaque formation in the bulb of common carotid, and hyperuricemia in male was not an independent factor associated with 5-year incidence plaque formation.

Objective To evaluate the safety and efficacy of percutaneous nephrolithotomy (PCNL) with B ultrasound-guided renal access in the lateral decubitus flank position for complex renal calculi. Methods From June 2004 to August 2009, 650 patients with renal stones≥20 mm underwent PCNL with B ultrasound-guided renal access in the lateral decubitus flank position. 512 men and 138 women,with a mean age of 38 years(range 11 - 78 years)and a mean stone size of 31 mm(range 20 - 58 mm). Results Successful access was achieved in 650 patients (100%). Minimally PCNL and PCNL were performed in 493 and 157 patients. Complete stone clearance rate was 86. 6% (563/ 650). The mean operative time was 72 min(range 35 - 145 min), and the mean hospital stay was 18d (range 9 - 32 d). There were no visceral injuries. Conclusions PCNL with B ultrasound-guided renal access in the lateral decubitus flank position is safe and convenient, and prevents harmful effects of radiation for the surgeon, the surgical team, and the patient.

AIM: To study the protective effect of edaravone on renal injury induced by chronic intermittent hypoxia and its effect on Caspase-1 mediated pyroptosis signaling pathway in rats. METHODS: Twenty four SPF male SD rats were randomly divided into normal control group, intermittent hypoxia group, intermittent hypoxia + normal saline group and intermittent hypoxia + edaravone group, with 6 rats in each group. The four groups of rats were placed in the closed feeding chamber for modeling. The oxygen concentration in the NC group was maintained at about 21%; the IH group, IH + NS group and IH + EDA group were given regular input of pure oxygen, pure nitrogen and compressed air to form anoxic-reoxygenation cycle (60 s hypoxic period + 60 s reoxygenation period). During the hypoxic period, the oxygen concentration in the chamber was reduced to 6%-7%, and the rats in the IH + EDA group were intraperitoneally injected with edaravone at a dose of 5 mg/kg per day before modeling, while the rats in the IH + NS group were intraperitoneally injected with normal saline at the same dose per day. After 8 weeks of modeling, blood and kidney tissue samples were collected to measure the levels of Crea and Urea in each group. The pathological changes and fibrosis degree of kidney were observed under light microscope after HE and Masson staining. The content of malondialdehyde (MDA) and activity of superoxide dismutase (SOD) were determined by chemical method. The expression levels of NLRP3, Caspase-1 and IL-1β in renal tissues were determined by immunohistochemical staining. The expression levels of caspase-1 and IL-1β in renal tissues were determined by Western blot. GSDMD and IL-18 mRNA were detected by RT-PCR. RESULTS: After intermittent hypoxia exposure, serum Crea and Urea were increased significantly (P < 0.01), renal tubules were damaged by pathology, collagen fiber deposition occurred in balloon space of renal units, MDA content was increased and SOD activity was decreased (P < 0.01). Caspase-1, NLRP3, IL-1β protein expression increased (P < 0.01 or P < 0.05), GSDMD mRNA and IL-18 mRNA amplification increased (P < 0.01); After Edaravone intervention, the above indexes showed a reverse trend compared with that after intermittent hypoxia exposure, and the pathological damage of kidney was reduced (P < 0.01 or P < 0.05). CONCLUSION: Chronic intermittent hypoxia may mediate kidney injury through oxidative stress activation of caspase-1 involved in the cell pyroptosis signaling pathway, while edaravone may inhibit the activation of pyroptosis signaling pathway by scavenging oxygen free radicals and down-regulating the level of oxidative stress in the body, thus playing a protective role in kidney.

【Objective】 To study the changes of platelet components(PC), apheresis platelets (AP) and pooled platelet concentrates (PPC) production of 19 provincial blood centers before and during the COVID-19 epidemic. 【Methods】 The data related to the collection of AP and the preparation of PPC from 2016 to 2021 of 19 provincial blood centers was collected. The production of PC, AP and PPC during the four years before the epidemic (i.e. 2016-2019) and during the COVID-19 epidemic (i.e. 2020 and 2021) were calculated respectively, and the change of production was analyzed. 【Results】 The total production of PC in 19 blood centers steadily increased from 2016 to 2019, with a decrease of 4.16% in 2020 and an increase of 15.60% in 2021, exceeding the output before the COVID-19 epidemic. In 2020, the production of PC of 42.11% (8/19) blood centers decreased compared with 2019, while 94.74% (18/19) in 2021 increased compared with 2020. The changes of AP output was basically consistent with the trend of PC. The total production of PPC in 2017 and 2018 both doubled compared to the previous year, while decreased by 67.98% in 2019, increased by 30.38% in 2020 and decreased by 27.08% in 2021. 【Conclusion】 The total production of PC kept increasing steadily between 2016 and 2019, but decreased in 2020 under the COVID-19 epidemic, with some blood centers being significantly affected. In 2021, with the strong support from government and various measures by blood centers, the total production of PC increased.
