BACKGROUND:Studies have shown that bone marrow mesenchymal stem cel transplantation can improve disease conditions by reducing inflammation.
OBJECTIVE:To explore the therapeutic efficacy of bone marrow mesenchymal stem cels on chronic asthma rats.
METHODS: A rat model of chronic asthma was established by intraperitonealy injected and aerosolized ovalbumin. After modeling, rats were given 4×105 and 8×105 bone marrow mesenchymal stem celsvia the tail vein, respectively. Thirty days later, the lung tissues were observed pathologicaly using hematoxylin-eosin staining; RT-qPCR and ELISA methods were employed to test the changes in interleukin-10, tumor necrosis factor-α and interferon-γ levels in lung tissue and peripheral blood, respectively.
RESULTS AND CONCLUSION:Rat models of chronic asthma were successfuly established after intraperitoneal injection of ovalbumin combined with aerosolized ovalbumin. After 30 days of cel treatment, the structure of lung tissues were obviously recovered, and the levels of interleukin-10, tumor necrosis factor-α and interferon-γ showed some improvement in lung tissue and peripheral blood, but there were no differences between the two groups. In conclusion, bone marrow mesenchymal stem cels show some potential role in the treatment of chronic asthma.

OBJECTIVE:To optimize the preparation technique of norcantharidin liposome(NL) and study its pharmaceutical properties. METHODS: With envelopment efficiency(EE), mean particle size and span of the liposome as indexes, the effects of thin-film dispersion method, injection method, reverse phase evaporation and reverse phase film-evaporation method on the EE and particle size of the NL were evaluated. And the uniform design was used to optimize the reverse phase film-evaporation preparation technique of NL with the amount of phospholipid (X1), the mass ratio of phospholipid/ cholesterol (X2), the sonde-type ultrasounding times (X3), the dilution times of buffer phosphate (X4), the volume ratio of oil/water phase (X5) and the mass ratio of lipoids/ drug (X6) as integrated indexes. A verification test was performed on the optimal technique. RESULTS: The formulation prepared by reverse phase film-evaporation technique exhibited the best EE. The preparation conditions of the optimized NL were as follows: X1=200 mg; X2=7∶1; X3=20 times; X4=50 times; X5=1∶4; X6=30∶1. The verification test showed that the EE, the mean particle size and the span of the liposome were (42.5?1.3)%, (210.9?2.1) nm and (0.61?0.12), respectively. CONCLUSION: NL was prepared successfully.

Objective To study the outcome of lost gallstones in peritoneal cavity. Methods Gallstones and bile collected from 51 patients undergoing laparoscopic cholecystectomy were analysed and cultured.One to three gallstones from each patient were placed into the peritoneal cavity of a corresponding Wistar rat on sterile condition. Results 8 rats died of peritoneal infection, intestinal fistula and ileus within one month. Abdominal wall abscess occured to one rat. All survival rats were sacrificed three months later. Pathologic results showed that the nidus of abscess appeared in tissue around the stone. Conclusions Lost gallstone is harmful to body. We should avoid gallstone lost in peritoneal cavity.

Recently, the incidence of both diabetes mellitus and diabetic foot has been increasing.Ischemia, neuropathy, and infection are major causes of diabetic foot ulcer. In addition to other conventional treatments, hyperbaric oxygen is an effective adjunctive therapy with less side-effects. Hyperbaric oxygen may play a role through different mechanisms in improving the prognosis of diabetic foot.

Objective To investigate the effect of recombinant rat augmenter of liver regeneration (rrALR) on the biological activities of rat glomerular mesangial cell(GMC) with or without IL-1?. Methods GMC proliferation and the level of TGF-? protein were determined by 3H-TdR incorporation and ELISA. Results The stimulating activity of IL-1? to rat GMC was enhanced by rrALR with the concentrations from 0.005 pg/ml to 0. 1ng/ml. But rrALR could not promote the proliferation of GMC without IL-1?. Conclusion rrALR may be a new mediator of inflammation, which promote proliferation and TGF-? secretion in rat GMC stimulated by IL-1?.

When the tracheotomy and tracheal intubation patients were treated in hyperbaric oxygen chamber,not ordi-nary facemask but specially made therapeutic facilities should be used.To select a more reasonable therapeutic facility for patients treatment in HBO chamber,all kinds of hyperbaric oxygen therapeutic facilities for the tracheotomy and tracheal intubation patients of our country in recent years are introduced from the aspects of material,facility,impermeability,ther-apeutic efficiency,influences on oxygen concentration in chamber,the advantages and disadvantages of each kind were demonstrated.

Karyotyping analysis is a classical cytogenetic method for the prenatal diagnosis of fetal chromosomal aberrations. In order to standardize fetal chromosomal karyotyping analysis and adapt to the development of medical genetics technology, the Committee for the Prevention and Control of Birth Defect, Chinese Association of Preventive Medicine has organized the formulation of this guideline. The content has covered general requirements and standards for the analysis of fetal chromosomal karyotypes, analysis of chromosomal mosaicisms, and methods for determining the resolution of G-banding, etc., with the purpose to serve the clinical practice.

The current situation of medical information was analyzed by displaying the co-appearance of countries and time, top 5 journals and co-appearance of subject headings in papers on medical information published in 1995-2014 with the papers on medical informatics covered in ISI Web of Science Database as an sample , in order to promote the study and provide reference for the related persons and institutions .

Objective To compare the outcomes of TOT and TVT procedure treating female intrinsic sphincter deficiency (ISD).Methods From May 2010 to September 2015,42 stress urinary incontinence (SUI) patients whose abdominal leak point pressure was less than 60 cmH2O were enrolled in this study.Thirty-five patients were followed up.The mean age was (56.8 ±10.5) years,with a range of 30-80 years.The mean history was(10.5 ± 9.1)years,with a range of 4 months to 30 years,with 26 (74.3％) of them being postmenopausal,5 (14.3％) having a history of pelvic surgery,and no pelvic organ prolapsed or hormone replacement.All of them were randomly divided into 2 groups to undergo either TVT operation (13 cases) or TOT operation (22 cases).The baseline characteristics of the two groups including age,length of history,urodynamic parameters and scale scores showed no significant difference.The scales including urinary incontinence severity score (UISS),detrusor instability score (DIS),Quality of Life Scale Evaluation (I-QOL),lower urinary tract symptoms affect score (UDI-6) were used.The outcomes between TVT group and TOT group were compared.Result After procedure,patients in TVT group got a lower UISS score than TOT group(17.2 ± 2.2 vs.17.7 ± 3.1),and their severity of urinary incontinence improved significantly (P ＜ 0.05).Patients from TVT group got a lower DIS score than TOT group (12.6 ± 4.2 vs.14.2 ± 3.5),and their detrusor instability symptoms improved more significantly (P ＜ 0.05).Patients from TVT group got a higher I-QOL score than TOT group(17.5 ± 14.5 vs.16.1 ± 13.0),and their quality of life improved more significantly (P ＜ 0.05).Patients from TVT group got a lower UDI-6 score than TOT group (10.1 ± 3.0 vs.11.2 ± 3.4),and their lower urinary tract symptoms improved more significantly (P ＜ 0.05).Conclusion Urinary incontinence of female ISD patients were improved greater by TVT than TOT procedure.
