Objective: We investigated changes in the intestinal flora of children with Mycoplasma pneumoniae pneumonia (MPP). Methods: Between September 2019 and November 2019, stool samples from 14 children with MPP from The Fourth Hospital of Baotou city, Inner Mongolia Autonomous Region, were collected and divided into general treatment (AF) and probiotic (AFY) groups, according to the treatment of "combined Bifidobacterium, Lactobacillus, Enterococcus, and Bacillus cereus tablets live". High-throughput 16S rDNA sequencing was used to identify intestinal flora. Results: Intestinal flora abundance and diversity in children with MPP were decreased. Both Shannon and Simpson indices were lower in the AF group when compared with healthy controls ( P < 0.05). When compared with healthy controls, the proportion of Enterorhabdus was lower in the AF group, while the proportion of Lachnoclostridium was higher ( P < 0.05). The proportion of Bifidobacteria and Akkermansia was lower in the AFY group but Enterococcus, Lachnoclostridium, Roseburia, and Erysipelatoclostridium proportions were higher. The proportion of Escherichia coli- Shigella in the AFY group after treatment was decreased ( P < 0.05). Conclusions The intestinal flora of children with MPP is disturbed, manifested as decreased abundance and diversity, and decreased Bifidobacteria. Our probiotic mixture partly improved intestinal flora disorders.

Objective:To investigate the effects of a one-way tracheostomy speaking valve based on neuromuscular electrical stimulation on aspiration in patients with dysphagia after tracheotomy for cerebral hemorrhage. Methods:From January to December, 2018, 37 patients with dysphagia after tracheotomy for cerebral hemorrhage were randomly divided into control group (n = 21) and experimental group (n = 16). Both groups accepted neuromuscular electrical stimulation, while the experimental group was trained to use one-way tracheostomy speaking valve additionally, for three weeks. They were assessed with Functional Oral Food Intake Scale (FOIS) and Penetration-Aspiration Scale (PAS) before and after treatment. Results:The scores of FOIS and PAS improved in both groups after treatment (|Z| > 3.544, P < 0.001), and was better in the experimental group than in the control group (|Z| > 2.094, P < 0.05). Conclusion:One-way tracheostomy speaking valve training based on neuromuscular electrical stimulation could improve swallowing and reduce aspiration of patients with dysphagia after tracheotomy.

Objective: To observe the effect of phlegm and blood stasis on the expressions of sirtuin 3(SIRT3)protein and urate transporter 1(URAT1) mRNA in skeletal muscle of diabetic rats with gout. Method: The 40 healthy rats, excepting the normal group, the remaining groups were fed with high-fat diet combined with low-dose streptozotocin solution (40 mg·kg^-1) once a day, with blood glucose "16.7 mmol·L^-1" as the criterion for the diabetes model. After 4 days, the 5% sodium urate solution was injected into the joint cavity once to induce the gout model. After the successful modeling, the Biling group (10 g·kg^-1), the indomethacin group (5 mg·kg^-1) and the pioglitazone group (10 mg·kg^-1) continued to be administered for 21 days. The normal group and the model group were given the same amount of normal saline. The expression of SIRT3 protein in skeletal muscle tissue was determined by Western blot, URAT1 mRNA expression in bone tissue was detected by quantitative real-time fluorescence polymerase chain reaction(Real-time PCR),and blood was collected to measure blood glucose (GLU), blood uric acid (UA) and C-reactive protein (CRP). Result: Compared with the normal group, GLU, UA and CRP in the model group were significantly increased (P<0.01). Compared with the model group, GLU in the Biling group and the pioglitazone group were decreased, and UA and CRP in the medicine group were significantly decreased (P<0.05,P<0.01). Compared with the normal group, the expression of SIRT3 protein in the skeletal muscle of the model group was significantly decreased (P<0.01), while the expression of SIRT3 protein in the skeletal muscle of the Biling group was significantly increased after administration (P<0.01). Compared with the model group, the expression of SIRT3 protein in the skeletal muscle of the sputum group was significantly increased (P<0.01), with no significant difference from the western medicine group. The results of the strip chart also showed that compared with the model group, the expression brightness of the model group was significantly weakened, while the expression brightness of the drug group was significantly enhanced. Compared with the normal group, the relative expression of joint URAT1 mRNA in the model group was significantly increased (P<0.01). Compared with the model group, the relative expression of URAT1 mRNA in each drug group was significantly down-regulated (P<0.01). The results of the strip chart also showed that expression brightness of the normal group was the weakest, while that of the model group was the highest, and the expression brightness of the Biling group and the western medicine group was significantly weakened. Joint pathology suggested that compared with the normal group, the pathological damage of the joints in the model group was severe, with a large number of inflammatory cell infiltration and fibrosis, synovial cell degeneration and necrosis. Compared with the model group, the degree of joint disease was significantly reduced after treatment with Biling Qutong prescription, with only a small amount of inflammatory cell infiltration and mild hyperplasia in synovial epithelium. Conclusion: Biling Qutong prescription with effects in purging turbidity, detoxifying and dredging collaterals can significantly reduce the content of serum inflammatory factor CRP, significantly increase the protein expression of SIRT3 in skeletal muscle tissue of model rats, lower the content of URAT1 mRNA, reduce the blood glucose and blood uric acid levels in diabetic gout rats, and protect joints.

Nine triterpenes compounds were isolated from the male flowers of Eucommia ulmoides by recrystallization and chromatographic techniques over silica gel, Sephadex LH-20, and RP-18 gel. Their chemical structures were identified on the basis of spectral analysis and as 3-oxo-12-en-ursane-28-O-α-L-arabinofuranosyl (1 --> 6) -β-D-glucopyranoside (1), 2α, 3β-dihydroxyurs-12-en-28-oic acid(28 --> 1) -β-D-glucopyranosyl ester (2), ursolic acid (3), α-amyrin (4), uvaol (5), ursolic acid acetate (6), 3-O-acetate oleanoic acid (7), betulinic acid (8), and betulinol (9). Compound 1 was a new compound, and compounds 2, 4-7 were isolated from the Eucommiu genus for the first time. Cytotoxic activity was tested for all the compounds against K562 and HepG2 cells. The results showed that only compound 3, exhibited cytotoxic activity.
