Objective To study the effects of Qingjinkangkuoyin (QJKKY) on TNF-α and NE in rats with bronchiectasis.Methods Models were established by intrabronchially injecting with pseudomonas aeruginosa,and divided into 5 groups by random:the QJKKY high dose treatment group (given high dose of QJKKY into stomach),the QJKKY low dose treatment group (given low dose of QJKKY),the levofloxacin group (given levofloxacin),the model group (given normal saline),and the normal contrast group (given normal saline).After 2 weeks of treatment,the histopathology of lung tissue,the levels of TNF-α and inflammatory cells in peripheral blood and NE in rats' lung tissue were detected.Results Compared with the model group (160.425±9.9293)ng/L,QJKKY could decrease the level of TNF-α in blood significantly [high dose of QJKKY treatment group was (137.133±6.1646)ng/L,P＜0.05]; the expression of inflammatory cells in serum were decreased significantly by QJKKY [high dose of QJKKY treatment group was (1.106± 0.3580) 109/L,P＜0.05].Low dose of QJKKY treatment group was (1.086 ±0.2433) 109/L,(P＜0.05) ; the expression of NE in lung tissue were decreased remarkably by QJKKY [high dose of QJKKY treatment group(80.697 ±4.5877)ng/L,P＜0.05]; low dose of QJKKY treatment group is (80.747±3.6925)ng/L,(P＜0.05); and the histopathologic change of lung tissue in QJKKY treatment groups were ameliorated under light microscope by HE staining.Conclusion Qingjinkangkuoyin could cure bronchiectasis by decreasing the expression of TNF-αin peripheral blood and NE in rats' lung tissue.

Objective:To explore the effects of norepinephrine combined with dobutamine on the hemodynamics,blood lactic acid,creatinine clearance rate (CCr),fractional excretion ofH2O (FEH2O) and fractional excretion of sodium (FENa) of patients with septic shock.Methods:120 cases of patients with septic shock from January 2016 to December 2016 were selected as the research objectives and randomly divided into two groups with 60 cases in each group.Dobutamine was given to both groups,then norepinephrine was additionally given to the observation group,dopamine was additionally given to the control group.The clinical effect,changes of hemodynamics,blood lactic acid,CCr,FEH2O and FENa levels before and after treatment were compared between two groups.Results:The blood lactic acid and FENa levels of both groups were gradually decreased at 6,12,24 and 48 hours after treatment and were significantly lower than those before treatment;the CCr and FEH2O levels were gradually increased and significantly higher than those before treatment (P＜0.01).The blood lactic acid and FENa levels were gradually decreased at 6,12,24 and 48 hours after treatment and were significantly lower than those of the control group at same time (P＜0.01),the FEH2O level was significantly higher than that of the control group at the same time (P＜0.01).The MAP,SVRI of both groups at 6,12,24 and 48 hours after treatment were significantly higher than those before treatment,but the CI at 24,48 hours after treatment were significantly higher than those before treatment (P＜0.01),the MAP of observation group at 6,12,24 and 48 hours after treatment were significantly lower than those before treatment (P＜0.01),the MAP at 6,12 hours after treatment were significantly higher than those before treatment (P＜0.01),the HR of observation group at 6,12,24 and 48 hours after treatment were significantly lower than those of the control group,but SVRI was significantly higher than those of the control group (P＜0.01).The mortality of observation group was 18.33％ at 28th days after treatment,which was 35.00％ in the control group and significantly higher than that of the observation group (P＜0.05).Conclusion:Norepinephrine combined with dobutamine could improve the hemodynamics,reduce the blood lactate level,improve the renal perfusion and prognosis of patients with septic shock.

Objective To study the effective hemostatic method for treating multiple trauma accompanied with hemorrhagic shock to increase the existence rate. Methods In treating 5 patients of multiple tauma accompanied with hemorrhagic shock, We used radiological embolism to injuried parenchymatous organs and injuried vessels to arrest the bleeding at first. After shock recovered, prompt exploration was made to repair injuried hollow viscus. Results After embolism and bleeding arrested, shocks in all 5 patients were corrected in short time; and no serious active hemorrhage was found after abdominal operation to repair the hollow viscus. All 5 patients survived after the operation. Conclusions The radiological embolism is simple,and has the little trauma and a good hemostatic effect,and needs short time. The method for treating multiple trauma can improve the salvage rate of multiple trauma accompanied with hemorrhagic shock and fit the treatment principle of multiple trauma.

OBJECTIVETo observe the clinical efficacy of shensong yangxin capsule (SYC) on ventricular premature beat (VPB) differentiated in TCM as palpitation of Qi-yin deficiency syndrome or Xin collateral stagnation syndrome, and cardiovascular autonomic nervous function in patients with coronary heart disease (CHD).

METHODSThe randomized, double-blind, parallel contrast method was adopted, patients were randomly assigned by 3:1 ratio into two groups. One hundred and sixty-five patients in SYC treated group and 56 in the control group (treated with Xinlvning tablet), and the therapeutic course for both groups was 4 weeks.

RESULTSThe clinical efficacy on VPB and in improving TCM syndromes was better in SYC group than that in the control group (P < 0.01). After treatment, the heart rate variability (HRV) and QT dispersion in the two groups were improved in a certain degree. The changes of SDNN, SDANN, SDNN Index and PNN50 in the two groups were significantly different (P < 0.05, P < 0.01), the efficacy in the treated group was superior to that in the control group.

CONCLUSIONSYC has definite effect on VPB and TCM Syndromes, it can obviously meliorate the activity of cardiovascular autonomic nervous system in the patients with CHD.

The present study aimed to explore the neuroprotective effect and possible mechanisms of rhGLP-1 (7–36) against transient ischemia/reperfusion injuries induced by middle cerebral artery occlusion (MCAO) in type 2 diabetic rats. First, diabetic rats were established by a combination of a high-fat diet and low-dose streptozotocin (STZ) (30 mg/kg, intraperitoneally). Second, they were subjected to MCAO for 2 h, then treated with rhGLP-1 (7–36) (10, 20, 40 µg/kg i.p.) at the same time of reperfusion. In the following 3 days, they were injected with rhGLP-1 (7–36) at the same dose and route for three times each day. After 72 h, hypoglycemic effects were assessed by blood glucose changes, and neuroprotective effects were evaluated by neurological deficits, infarct volume and histomorphology. Mechanisms were investigated by detecting the distribution and expression of the nuclear factor erythroid-derived factor 2 related factor 2 (Nrf2) in ischemic brain tissue, the levels of phospho-PI3 kinase (PI3K)/PI3K ratio and heme-oxygenase-1 (HO-l), as well as the activities of superoxide dismutase (SOD) and the contents of malondialdehyde (MDA). Our results showed that rhGLP-1 (7–36) significantly reduced blood glucose and infarction volume, alleviated neurological deficits, enhanced the density of surviving neurons and vascular proliferation. The nuclear positive cells ratio and expression of Nrf2, the levels of P-PI3K/PI3K ratio and HO-l increased, the activities of SOD increased and the contents of MDA decreased. The current results indicated the protective effect of rhGLP-1 (7–36) in diabetic rats following MCAO/R that may be concerned with reducing blood glucose, up-regulating expression of Nrf2/HO-1 and increasing the activities of SOD.

Objective:To observe the multimodal imaging features of the eyes with acute syphilitic post-polar squamous chorioretinitis (ASPPC) at different stages of disease.Methods:A retrospective case study. From July 2016 to March 2019, 8 patients (11 eyes) of ASPPC patients diagnosed in the ophthalmological examination of Yunnan Second People's Hospital were included in the study. Among them, there were 7 males (10 eyes) and 1 female (1 eye); the average age was 48.7±8.9 years; the average course of disease was 13.24±11.30 months. All patients underwent fundus color photography, infrared photography (IR), FAF, FFA, OCT, OCT angiography (OCTA). According to the stage and characteristics of the disease, the affected eyes were divided into acute phase and absorption phase, with 7 and 4 eyes respectively. We observed the color fundus images of ASPPC, IR, FAF, FFA, OCT, OCTA image characteristics of different disease stages.Results:In the acute phase, the posterior pole subretinal yellow-white squamous lesions, neuroepithelial detachment, and yellow-white exudates were observed in fundus color photography; uneven infrared reflections can be seen in the lesion area by IR; the posterior pole was round or scaly with strong autofluorescence in FAF, the range was larger than the fundus color photography; FFA arteriovenous stage lesions showed fuzzy weak fluorescence, the fluorescence gradually increased with time, the late stage showed a round-shaped strong fluorescence, surrounded by a weak fluorescence ring, and the area with thick exudation was covered by fluorescence; the neuroepithelium of the diseased area was detached, the uniform strong reflection signal can be seen in it by OCT. In the absorption phase, fundus color photography showed the yellow-white scaly lesions under the posterior retina absorption, and the pigment was slightly depleted; IR showed the mottled infrared reflection in the lesion area was significantly reduced compared with the acute phase; FAF showed the posterior spot-like strong autofluorescence, including "leopard spot-like changes" 3 eyes; FFA showed mottled fluorescent staining in the lesion, and no fluorescein leakage or accumulation; OCT showed needle-like protrusions in the RPE layer, and the outer membrane and ellipsoid zone were unclear; OCTA showed weakened choroidal capillary blood flow signal, the signal was missing in some areas.Conclusions:In the acute phase of ASPPC, the posterior pole subretinal shows yellow-white squamous lesions, neuroepithelial detachment, yellow-white exudate, FFA shows late fluorescein leakage in the lesion area; in the absorption period, the fundus shows yellow-white lesions have been absorbed, and FFA shows fluorescence dyed without any leakage. OCT indicates that the RPE, outer membrane and ellipsoid zone are damaged to varying degrees. OCTA indicates that the choroid of the diseased area had weakened blood flow signal.
