ABSTRACT
Objective To observe the effect of tiopronin combined with glutathione on the levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), glutamyltransferase (GGT),blood fat and laminin (LN) in patients with non-alcoholic fatty liver. Methods A total of 84 non-alcoholic fatty liver patients admitted to our hospital from March 2018 to September 2019 were selected and randomly divided into control group and observation group, with 42 cases in each group. The control group was treated with tiopronin, and the observation group was treated with glutathione and tiopronin. The levels of ALT, AST, GGT and blood fat were recorded and compared before and after treatment. Results After treatment, the levels of ALT, AST and GGT in the two groups were significantly lower than before treatment (P<0.05). After treatment, the levels of ALT, AST, and GGT in the observation group were different from those in the control group, which was statistically significant (P<0.05). Before treatment, there was no difference in serum TC, TG, and LDL levels between the two groups, which was not statistically significant (P>0.05). The above-mentioned serum levels of the observation group after treatment were lower than those in the control group, and there was a difference, which was statistically significant (P<0.05); the levels of PCⅢ, PCⅣ, and LN in the treatment group after treatment were significantly lower than those of the control group. The difference was statistically significant (P<0.05). Conclusion The application of tiopronin combined with glutathione in the treatment of non-alcoholic fatty liver can promote the recovery of liver function and reduce the concentrations of TC, TG and LDL, which is worthy of clinical promotion.

ABSTRACT
<p><b>OBJECTIVE</b>To observe the role of myeloperoxidase(MPO)and eosinophilic cationic protein(ECP)in the airway inflammation and their correlation with clinical feature in asthma-COPD overlap (ACO) patients.</p><p><b>METHODS</b>Twenty patients with COPD, 20 with asthma, 20 with ACO and 20 control subjects underwent pulmonary function test for measurement of forced expiratory volume in 1 second (FEV), forced vital capacity (FVC), peak expiratory flow (PEF), and maximum midexpiratory flow (MMF). COPD assessment test (CAT) was used to evaluate the clinical symptoms of the patients with COPD and ACO. The asthma control test (ACT) was used to evaluate the asthma control in the patients with asthma and ACO. Induced sputum samples were collected from the subjects for analysis of neutrophil and eosinophil ratios, and enzyme-linked immunosorbent assay was used to determine the expression levels of MPO and ECP in the sputum.</p><p><b>RESULTS</b>No significant difference was observed in the CAT scores between ACO group and COPD group (> 0.05). Compared with the asthma group, the patients with ACO had significantly lower ACT scores and lower FEV, PEF and MMF ( < 0.05). The patients with ACO had significantly higher FVC and sputum eosinophil ratio than those with COPD ( < 0.05), and a higher sputum neutrophil ratio than those with asthma ( < 0.01). In ACO group, the MPO level in sputum was significantly higher than that in the asthma group ( < 0.05), while sputum ECP level was significantly higher than that in both the asthma group and COPD group ( < 0.05 or 0.01). In ACO group, sputum MPO level was positively correlated with sputum neutrophil ratio (=0.8358, < 0.01) but was not correlated with CAT score or FEV (> 0.05); sputum ECP level was positively correlated with sputum eosinophil ratio (=0.4666, < 0.05) and was inversely correlated with ACT score (=-0.4966, < 0.05) and FEV (=-0.4610, < 0.05).</p><p><b>CONCLUSIONS</b>Both neutrophilic and eosinophilic inflammations occur in the airway of patients with ACO, and their sputum ECP level is negatively correlated with asthma control and obstructive airflow limitation.</p>
ABSTRACT
Objective To evaluate the therapeutic effect of ESWL combined with urinary stone decoction and ear acupoint pressure for the patients with renal and ureteral calculi.Methods A total of 110 patients with renal and ureteral calculi were randomly divided into the Chinese medicine (CM) and conventional groups, 55 in each group. Both groups were given ESWL treatment as basic treatment. Chinese medicine group were given the urinary stone decoction and auricular acupressure, and the conventional group used stone granules. Both groups were treated for 2 weeks. According to the photography of ultrasound, the changes of calculi, time of lithagogue, pain relief after operation and the effect rates of pain relief on abdomen and waist, of remission of haematuria, and of urinate pain. ResultsAfter treatment, the successful rates of operation in the CM group was 90.9% (50/55), and conventional group was 76.4% (42/55). There was significant difference between 2 groups (χ2=4.251,P=0.009). The time of stone removal in CM group was significantly shorter than that in the conventional group (7.3 ± 3.8 dvs. 11.2 ± 4.3 d,t=4.032,P<0.001). After 1st, 3rd, 5th, 7th days, the VAS pain scores in the CM group were significantly lower than those in the conventional group (4.1 ± 0.8vs. 5 ± 1.2,t=4.783;4.5 ± 0.9vs. 5.3 ± 1.3,t=4.492; 3.8 ± 0.8vs. 4.5 ± 0.8,t=4.503; 2.2 ± 0.8vs. 2.9 ± 0.9,t=3.691; allP<0.01). After 7th day, the rates of abdominal pain relief was 60% (33/55), pain relief was 79.1% (34/43), the remission of hematuria was 81% (17/21) in the CM group, and the control group were 40% (22/55), 59.6% (28/47), 52% (13/25). There were significant differences between 2 groups on these indices (χ2 values were 4.400, 3.982, 4.217,P values were 0.036, 0.046, 0.040).Conclusions The ESWL combined with urinary stone decoction and ear acupoint pressure could improve the symptoms of patients with kidney ureteral stones.
ABSTRACT
AAV-ITR gene expression mini vector is a double-strand or single-strand DNA that only contains inverted terminal repeats of adeno-associated virus, cis-elements and gene of interest and does not contain any other foreign DNA sequences. We prepared Bac-ITR-EGFP and Bac-inrep. Spodoptera frugiperda cells were infected with Bac-ITR-EGFP (P3) and Bac-inrep (P3). Up to 100 μg of AAV-ITR-EGFP gene expression mini vectors were extracted from 2 x 10(7) cells of Sf9 72 h after infection. The gel electrophoresis analysis shows that most forms of AAV-ITR-EGFP gene expression mini vector were monomer and dimer. The mini vector expression efficacy was examined in vitro with HEK 293T cells. The EGFP expression was observed at 24 h after transfection, and the positive ratio reached 65% at 48 h after transfection.

We tried to construct and identify the recombinant replication-deficient adenovirus vector coding for human tissue factor pathway inhibitor 2 (hTFPI-2) gene by AdMax system in HEK293 cells. Firstly, we obtained hTFPI-2 gene from the recombinant plasmid pIRES2-EGFP-TFPI-2 by PCR using primers with restriction endonuclease site of EcoRI or SacI. After digesting the hTFPI-2 gene and plasmid PDC316-IRES-EGFP shuttle vector, we ligated them with T4 ligase and formed the recombinant shuttle vector PDC316-IRES-EGFP-hTFPI-2. It was confirmed that the ligation product was inserted the gene of hTFPI-2 correctly by sequencing. Then we took cotransfection of HEK293 cells with the recombinant shuttle vector and genomic plasmid pBHGloxdeltaE1,3Cre by liposome lipofectamine2000, and finished the package of recombinant adenovirus Ad-hTFPI-2. The results of the PCR test and restriction endonuclease digestion confirmed the successful construction of the recombinants Ad-hTFPI-2. Furthermore, we measured the titre of Ad-hTFPI-2 with the aid of green fluorescence protein expression after multiplication and purification. The titre was 0.931 x 10(12) pfu/ml. Finally, we infected U937 monocytes by purified Ad-hTFPI-2, and determined the infection efficiency and the TFPI-2's level and activity. The efficiency of Ad-hTFPI-2 infection in U937 cells was 89.33%. After infected by Ad-hTFPI-2, the TFPI-2's level in supernatant increased about 7 fold. Also the TFPI-2 in supernatant had activities of inhibiting trypsin and plasmin. The recombinant adenovirus with the hTFPI-2 gene was constructed successfully. It will be helpful for the further investigation of its potentiality to be applied in antiatherosclerosis.
