The mainstay of treatment of laryngopharyngeal reflux focuses on a concoction involving proton-pump inhibitor and modified beneficial behaviors, sometimes referring to medications like H2-R blocker etc. Therapeutic effect seems to be promising although may at times be challenged by conflict researches. Voice therapy and voice parameters emerge to provide a grand new perspective in treatment and evaluation of this disease.

The proper orthogonai decomposition (POD) method for the instatiouary Navier-Stokes equations is considered. Several numerical approaches to evaluating the POD eigenfunctions are presented. The POD eigenfunctions are applied as a basis for a Galerkin projection of the instationary Navier-Stokes equations. And a low-dimensional ordinary differential models for fluid flows governed by the instationary Navier-Stokes equations are constructed. The numerical examples show that the method is feasible and efficient for optimal control of fluids.

[ABSTRACT]OBJECTIVETo diagnose laryngopharyngeal reflux (LPR) by using two methods: 24h pH monitoring and RSI combined with RFS scales. To research the voice characteristics of patients with LPR and changes of voice parameters before and after PPIs therapy, and to use voice parameters to help diagnosing and evaluating treatment effect of LPR.METHODSThe patients visited department of Otolaryngology head & neck surgery of Peking University Third Hospital from August 2012 to August 2013 were included in this study. There were 26 LPR patients diagnosed by 24 hr pH-MII monitoring (pH group) and 26 LPR patients diagnosed by RSI combined with RFS (questionnaire group). Another 52 subjects without laryngeal or pharyngeal symptoms were as control group. All subjects underwent MDVP examination. The patients from pH group and questionnaire group took esomeprazole 20 mg bid for one month, afterwards MDVP was examined again. The voice related parameters were compared before and after medication therapy.RESULTSComparing data between LPR patients and normal subjects, Jitter, Shimmer, NHR had significant difference (P<0.05), and F0, MPT had no significant difference (P>0.05) before treatment. After PPIs therapy there was no significant difference between each group (P>0.05).CONCLUSIONAbnormal voice parameters were existed in LPR patients. After PPIs treatment, voice related parameters improved apparently.

Objective To investigate the changes of serum procalcitonin (PCT), interleukin-6 (IL-6) and C reactive protein (CRP) in children with Henoch-Sch?nlein purpura (HSP) combined with surgical complications. Methods From January 2010 to June 2013, 48 children with HSP combined surgical complications were enrolled, the fasting venous blood were obtained in day 1, 3, 5 of admission and before discharge. Meanwhile, 30 healthy children were selected as control. Results Compared with the control group, the levels of serum PCT and IL-6 in day 1, 3, 5 of admission, and the levels of serum CRP in day 1, 3 of admission were higher in children with HSP combined with surgical complications (all P<0.01). The differences of levels of serum PCT, CRP and IL-6 in day 1, 3, 5 of admission and before discharge were statistically signiifcant between surgical group and non-surgical group. All these indicators showed a gradual downward trend. Compared with surgical group, the levels of serum PCT and IL-6 in day 3, 5 of admission and serum CRP in day 5 of admission were signiifcantly lower in non-surgical group (P<0.05). There were positive linear correlations between the level of serum PCT and IL-6, and between the level of PCT and CRP (r=0.48, 0.62, P<0.01). Conclusions The changes of serum PCT, IL-6 and CRP may be associated with the occurrence of surgical complications in children with HSP, monitor these indicators may help to assess the condition and to guide the treatment.

OBJECTIVETo prepare pravastatin sodium-loaded chitosan microspheres to allow sustained drug release.

METHODSThe drug-loaded chitosan microspheres were prepared by using genipin as the cross-linker. The influences of molecular weight of chitosan, volume ratio of oil and water, reaction temperature, and stirring speed on the formation of chitosan microspheres were investigated. The morphology of the microspheres was observed using scanning electron microscopy. The encapsulation efficiency, swelling ratio under different pH conditions, and in vitro drug release were measured.

RESULTSThe in vitro release of pravastatin sodium could last for at least 31 days. The drug release rate varied with the reaction condition. The drug entrapment efficiency of the microsphere was 54.7%. The optimal processing conditions were as follows: chitosan viscosity of 200-400 mPa·s, oil-water proportion of 10:1, stirring speed of 850 r/min, and reaction temperature at 40 degrees celsius;.

CONCLUSIONThe pravastatin sodium-loaded microspheres show good sustained drug release property, and the drug release rate can be modified by controlling the cross-linking time.

Objective:To explore the protective effect of puerarin on hypoxia/reoxygenation (H/R)-induced acute kidney injury(AKI)in vitro.Methods:HK-2 cells were treated with H/R for simulating ischemia reperfusion injury(IRI)in vivo. The experimental groups included control group, H/R treatment group(0/6/12/24 h), H/R 24 h + puerarin treatment group(puerarin, Pue), H/R 24 h + Pue+ 3-methyladenine(3-MA)treatment group and H/R 24 h+ 3-MA treatment group. Immunoblotting was employed for detecting the expression changes of autophagy-related proteins, CCK-8 for examining cell proliferation, electron microscopy for observing autophagosome formation and TUNEL for detecting apoptosis.Results:As compared with control group, the expression of LC3-II rose in H/R 24 h group, the expression of autophagy marker P62 declined, count of autophagosome increased, cell viability decreased and cellular inflammation occurred. Puerarin had similar effects to 3-MA. As compared with H/R 24 h group, puerarin could reverse the changes in the expression levels of LC3 and P62 induced by H/R( P<0.05). There were greater cell viability, reduced autophagosome count and lessened cell apoptosis( P<0.05). At the same time, protein expression levels of HMGB1, TLR4 and NF-κB dropped( P<0.05). Conclusions:Puerarin suppresses autophagy through HMGB1/TLR4/NF-κB axis for lessening ischemia-reperfusion injury an in vitro model.

Objective:To correlate peripheral blood hypersensitive C-reactive protein (hs-CRP) with cognitive function in patients with depression.Methods:Seventy-five patients with depression who received treatment in the Second People's Hospital of Lishui from January 2019 to May 2020 were included in the depression group. An additional 50 healthy controls were included in the control group. The MATRICS Consensus Cognitive Battery (MCCB) was used to evaluate participates' cognitive function. Serum hs-CRP level was determined using enzyme-linked immunosorbent assay.Results:Speed of processing, working memory, verbal learning, visual learning and reasoning/problem-solving scores in the depression group were significantly lower than those in the control group ( t = 10.774, 2.774, 9.840, 5.064, 7.915, all P < 0.01). Serum hs-CRP level in the depression group was significantly higher than that in the control group [(13.05 ± 2.94) mL vs. (1.13 ± 0.18) mL, t = 28.595, P < 0.01]. Speed of processing, working memory, verbal learning, visual learning and reasoning/problem-solving scores in patients with moderate and severe depression were significantly lower than those in patients with mild depression. Serum hs-CRP level in patients with moderate and severe depression was (10.41 ± 2.21) mg/L and (25.71 ± 4.04) mg/L, respectively, which was significantly higher than that in patients with mild depression [(3.03 ± 0.49) mg/L, t = 3.015, 3.370; 3.903, 3.441; 3.541, 3.604; 4.503, 4.661; 4.001, 3.980; 4.035, 3.669, all P < 0.01]. Speed of processing, working memory, verbal learning, visual learning and reasoning/problem-solving scores in patients with severe depression were significantly lower than those in patients with moderate depression ( t = 8.331, 5.227, 10.031, 6.003, 9.416, all P < 0.01). Serum hs-CRP level in patients with severe depression was significantly higher than that in patients with moderate depression [(25.71 ± 4.04) mg/L vs. (10.41 ± 2.21) mg/L, t = 11.005, P < 0.01]. Pearson correlation analysis showed that serum hs-CRP level in patients with depression was remarkably negatively correlated with speed of processing, working memory, verbal learning, visual learning and reasoning/problem-solving scores (all P < 0.01). Conclusion:Serum hs-CRP level in patients with depression is greatly increased, can reflect the severity of depression and is related to cognitive function.
