Objective:To investigate the clinical efficacy of radial extracorporeal shockwave therapy(ESWT)for scapulohumeral periarthritis in the elderly.Methods:A total of 82 patients diagnosed with scapulohumeral periarthritis at the rehabilitation medicine department of our hospital from July 2016 to January 2019 were retrospectively analyzed.The visual analogue score(VAS), Constant-Murley score(CMS), range of motion(ROM), adverse reactions, curative effectiveness and survival analysis were examined before treatment and at several time points within 6 months of treatment.Results:Compared with pre-treatment, the VAS, CMS, ROM, curative effects and survival analysis of patients with primary and secondary scapulohumeral periarthritis improved after treatment in both the conventional rehabilitation therapy group and the conventional rehabilitation therapy combined with ESWT group(all P<0.05). The short-term effects(2 weeks and 1 month after treatment)were better in the conventional rehabilitation therapy combined with ESWT group than in the conventional rehabilitation therapy group( P<0.05). There was no significant difference in long-term effects(2, 4 and 6 months after treatment)between the two groups( P>0.05). For patients with primary scapulohumeral periarthritis, conventional rehabilitation therapy combined with ESWT had advantages over conventional rehabilitation therapy in reducing the VAS score and improving shoulder function(CMS score and ROM)( P<0.05). For patients with secondary scapulohumeral periarthritis, conventional rehabilitation therapy combined with ESWT was better in reducing VAS than conventional rehabilitation therapy( P<0.05), while there was no significant difference in shoulder function improvement between the two groups(all P>0.05). Conclusions:Conventional rehabilitation combined with ESWT can relieve shoulder pain, improve range of motion and has a good safety profile in the treatment of scapulohumeral periarthritis in the elderly, but there is no significant difference in long-term efficacy between conventional rehabilitation therapy and conventional rehabilitation therapy combined with ESWT.

Objective To evaluate the efficacy of intravenous methylprednisolone for prevention of tracheal intubation-related laryngopharyngeal complications.Methods Three hundred ASA Ⅰ or Ⅱ patients,aged 20-50 yr,weighing 50-80 kg,undergoing elective surgeries,requiring tracheal intubation under general anesthesia,were included and randomized into 5 groups (n =60 each).Methylprednisolone 40 and 80 mg were injected intravenously at 30 min before induction of anesthesia in groups Ⅰ and Ⅱ,respectively,while the equal volume of normal saline was given instead in group Ⅲ.Methylprednisolone 40 and 80 mg were injected intravenously at 30 min before extubation in groups Ⅳ and Ⅴ,respectively.The sore throat,hoarseness and cough were recorded within 24 h after extubation and the severity was evaluated at 1 and 24 h after extubation.Results There was no significant difference in the incidence and severity of sore throat,hoarseness and cough between the five groups (P ＞ 0.05).Conclusion Intravenous methylprednisolone can not effectively prevent tracheal intubation-related laryngopharyngeal complications in patients.

Objective To investigate the effects of methylprednisolone on neurocyte apoptosis in rats with severe acute pancreatitis(SAP).Methods Thirty-six SD rats were divided into sham operation group,SAP group and methylprednisolone group(12 rats in each group).SAP model was constructed by injecting 5%sodium taurodeoxycholate into biliary-pancreatic duct.Serum amylase,interleukin-6(IL-6),tumor necrosis factor α (TNF-α),volume of aseites and histopathological changes of pancreas were determined.The mRNA expressions of Bcl-2 and Bax in brain tissue were analyzed by RT-PCR.and neuroeyte apoptosis was detected by TUNEL method.Results The levels of serum IL-6 and TNF-α were significantly increased:the expression of Bcl-2 mRNA in brain tissue was down-regulated;the expression of Bax mRNA was up-regulated;the Bcl-2/Bax ratio Was decreased:the apoptosis of the neurocytes was increased in SAP group.Compared with SAP group,the levels of serum IL-6 and TNF-α were significantly decreased;the expression of Bcl-2 mRNA was unchanged but the expression of Bax mRNA was down-regulated in brain tissue,so the Bcl-2/Bax ratio was elevated significantly;the rate of the ueurocyte apoptosis in brain tissue were reduced in methylprednisolone group.Conclusions The apoptosis of neurocytes in brain tissue may be one of the factors causing pancreatic encephalopathy.Methylprednisoione can inhibit the release of IL-6 and TNF-α.improve the balance of Bcl-2 and Bax expression and decrease the apoptosis of neurocytes in brain tissue.

OBJECTIVE:To study the effect and mechanism of tandospirone citrate (TC) on blood pressure in spontaneously hypertensive rats (SHR). METHODS:SHR were divided into model group,positive control group (Levamlodipine besylate tab-lets,2.5 mg/kg),TC high-dose,medium-dose,low-dose groups(TC capsules,40,20,10 mg/kg),8 in each group. Other 8 nor-mal rats were chosen as normal control group. The rats were intragastrically administrated medicines,once a day,for 28 d. Systolic blood pressure(SBP)before first administration and after 0.5,1,1.5,2,3,4 h of administration in each group were measured, and SBP after 1 h of administration were measured once every 7 d. After last administration,nitric oxide(NO)content in serum, endothelin,renin,angiotensin Ⅱ(Ang Ⅱ) and norepinephrine (NE) contents in plasma were detected. RESULTS:In single ad-ministration,compared with model group,SBP in 0.5,1 h in positive control group and TC groups after first administration were obviously decreased (P<0.05 or P<0.01),then SBP were obviously decreased only in positive control group and TC high-dose group (P<0.05 or P<0.01). In multiple administration,compared with model group,SBP in 7th,14th,28th day of administra-tion in positive control group and TC high-dose,medium-dose groups were obviously decreased(P<0.05 or P<0.01). Compared with model group,NO content in serum in positive control group,TC high-dose group were obviously increased;endothelin,re-nin,Ang Ⅱ and NE contents in plasma were obviously decreased (P<0.05 or P<0.01). Compared with positive control group, NO content in serum in TC groups was obviously decreased;endothelin,renin,Ang Ⅱ and NE contents in plasma were obviously increased in TC medium-dose group (P<0.05). CONCLUSIONS:TC can obviously decrease the blood pressure of SHR. The mechanism may be associated with adjusting the balance of NO and endothelin,and decreasing renin,AngⅡand NE contents.

A method for the determination of B6-pyridoxamine (PAM), pyridoxal (PAL) and pyridoxine (POL) by RPLC was proposed. The procedure included the addition of 0.1M H2SO4 to the sample, hydrolysis for 30 min at 120℃, centrifuging, filtration and direct analysis by ODS Cl8 column. PAM, PAL and POL were completely separated, when the flow rate of the mobile phase (pH2.0-2.1) was 1.0-1.5ml/min. Quantitation by a fluorescent detector was performed with Exc: 293 nm and Em: 395 nm. The recovery ranged from 99 to 103% with CV 5.0-5.3%. The method was simple, rapid, sensitive and reproducible.

Objective To discuss the experiences in successful treatment of hyperacute traumatic intracranial hematoma with percutaneous puncture and craniotomy.Methods Pereutaneous puncture and craniotomy was performed in 12 patients with hyperacute traumatic intracranial hematomas including seven with subdural hematoma,three with epidural hematoma and two with episubdural hematoma.Before operation,there found enlargement of bilateral pupil in six patients,enlargement of unilateral pupil in six and changed breathing rhythmicity in eight.Glasgow Coma Scale(GCS)was 3 points in four patients,4 points in six and 7 points in two.Results After pereutaneous puncture,enlarged pupil was retracted at different degrees in nine patients and spontaneous breathing conditions improved in seven.After crani otomy,two patients died within 24 hours,four died after 24 hours but six patients survived.The follow-up for 0.5-2 years showed four patients with sound Glasgow Outcome Score,two at vegetative state and six deaths.Conclusion Percutaneous puncture combined with craniotomy is an effective way for hyperacute intracranial hematoma.

This study is to investigate the inhibitory effect of kaempferol on inflammatory response of lipopolysaccharide(LPS)-stimulated HMC-1 mast cells. The cytotoxicity of kaempferol to HMC-1 mast cells were analyzed by using MTT assay and then the administration concentrations of kaempferol were established. Histamine, IL-6, IL-8, IL-1β and TNF-α were measured using ELISA assay in activated HMC-1 mast cells after incubation with various concentrations of kaempferol (10, 20 and 40 µmol.L-1). Western blot was used to test the protein expression of p-IKKβ, IκBα, p-IκBα and nucleus NF-κB of LPS-induced HMC-1 mast cells after incubation with different concentrations of kaempferol. The optimal concentrations of kaempferol were defined as the range from 5 µmol.L-1 to 40 µmol.L-1. Kaempferol significantly decreased the release of histamine, IL-6, IL-8, IL-1β and TNF-α of activated HMC-1 mast cells (P<0.01). After incubation with kaempferol, the protein expression of p-IKKβ, p-IKBa and nucleus NF-κB (p65) markedly reduced in LPS-stimulated HMC-1 mast cells (P<0.01). Taken together, we concluded that kaempferol markedly inhibit mast cell-mediated inflammatory response. At the same time, kaempferol can inhibit the activation of IKKβ, block the phosphorylation of IκBα, prevent NF-KB entering into the nucleus, and then decrease the release of inflammatory mediators.
