Methods Seventy six cases of asthmatic patients were diagnosed according to the body fluid theory of Uygur Medicine. Among them,there were 30 cases of asthmatic patients with Abnormal Savda and 46 cases of asthmatic patients with non-abnormal Savda. The level of serum ECP,T-IgE,S-IgE and FEV1 were tested quantitively. Results There were significant differences on the level of serum ECP,T-IgE,S-IgE in all three groups (P

OBJECTIVETo innovatively establish a new platform of myocardial ischemia-reperfusion injury (MIRI) animal model by observing abnormal savda carrier MIRI indicators, and to observe changes of myocardial ultrastructure.

METHODSAccording to Uyghur medical theories, an abnormal savda carrier animal model was established and confirmed using multifactor, and then MIRI models set up. Totally 36 male white SD rats were randomly divided into the normal sham-operation group, the normal operation group, the model sham-operation group, and the model operation group, 9 in each group. ECG changes, myocardial enzymes (CK-MB), and cardiac troponin (cTnT), and ultramicrostructures were observed.

RESULTSCompared with the normal sham-operation group, some damage of ultramicrostructures occurred in heart muscles of rats in the normal operation group and the model operation group, such as lowered myoplasm density, loosely arranged myofilament, dilated myofibris, reduced mitochondria number, vacuole and swelling mitochondrion. Ultramicrostructural damage of cardiac muscle cells was more severe in rats of the model operation group. Compared with the normal sham-operation group, CK-MB and cTnT increased in the normal operation group with statistical difference (P < 0.01). Compared with the normal sham-operation group, there was no statistical difference in CK-MB or cTnT in the model sham-operation group (P > 0.05). Compared with the model operation group, CK-MB and cTnT obviously decreased in the model sham-operation group and the normal operation group with statistical difference (all P < 0.01).

CONCLUSIONAbnormal savda carrier MIRI model established in this experiment could provide favorable conditions for further MIRI intervention treatment.

Objective:To discuss the clinical features, treatment and prognosis of renal mesenchymal malignancy.Methods:Retrospective analysis was performed on the clinical data of 48 patients with renal mesenchymal malignancies admitted from January 2005 to June 2019.The patients' age ranged from 16-79 years, including 29 males and 19 females. There were 21 cases of Han nationality and 27 cases of ethnic minorities. The main complained of lumbago were 31 cases, bloating 8 cases, blood urine 2 cases, and 6 cases by physical examination. And one case was seen in orthopedics due to upper arm pain. The patient's completion of the examination indicated a tumor of kidney origin. CT examination mostly showed renal space-occupying lesions. After enhancement, the tumor was irregularly enhanced, with unclear edges, which was difficult to distinguish from renal carcinoma. The tumors were on the left in 30 cases and on the right in 18 cases. All patients perfected preoperative blood routine, biochemical, coagulation and other examinations. Prothrombin time was normal in 39 cases. Clinical staging was conducted according to the imaging results at the time of initial diagnosis. 7 were in clinical Stage T 1, 16 were in Stage T 2, 20 were in stage T 3, and 5 were in stage T 4.Distant metastases were found in 8 cases, including 4 lung metastases, 2 retroperitoneal metastases, and 2 bone metastases. 13 patients underwent needle biopsy to confirm the diagnosis. Among the 48 cases in this group, 29 cases were diagnosed as renal tumor, 12 cases were diagnosed as renal space occupying lesions, and 7 cases were diagnosed as retroperitoneal space occupying. 17 underwent radical nephrectomy, 22 underwent partial nephrectomy, and 9 did not receive surgical treatment after needle biopsy. Results:Among the 48 patients, Conventional pathology confirmed 17 cases as leiomyosarcoma, 17 cases as liposarcoma, and 14 cases as other types of mesenchymal malignancies. Follow-up ranged from 7 to 180 months, with an average follow-up of 38.8 months. Thirty patients died, and the average survival time was 39 months. The 5-year survival rates of leiomyosarcoma, liposarcoma and other types of tumors were 18.2%, 30.8% and 50.1%, and the difference was statistically significant ( P=0.047). The 5-year survival rates of patients with normal and abnormal prothrombin time were 36.8% and 11.0%, the difference was statistically significant ( P=0.018). The 5-year survival rates of radical surgery and partial nephrectomy were 44.6% and 29.8%, and the difference was statistically significant ( P<0.05). The 5-year survival rates of T 1, T 2, T 3 and T 4 patients were 40.0%, 31.6%, 35.4% and 0, and the differences were statistically significant ( P=0.020). Multivariate analysis showed that preoperative prothrombin time ( P=0.013), clinical T stage ( P=0.030) and surgical method ( P=0.006) were independent factors affecting the prognosis of patients with RMM. Conclusions:Renal mesenchymal malignant tumor is rare, and highly malignant. Preoperative needle biopsy did not affect the prognosis of RMM. Patients with normal prothrombin time, early clinical staging and radical surgery had better prognosis. Renal liposarcoma has a better prognosis than renal leiomyosarcoma.

Abstract: Objective　To prepare a microparticle delivery system that regulates the release rate of extracellular vesicles (EVs), and to exert long-term enhancement of liver cell proliferation after only one intervention. Methods EVs was extracted by differential centrifugation. The structure of the EVs was observed by transmission electron microscopy and the membrane marker protein of EVs was detected by Western blotting. EVs-PLA microspheres with "core-shell" structure were prepared by emulsion-solvent evaporation method. Scanning and transmission electron microscopy were used to detect the morphology of EVs-PLA microspheres and EVs. The release test detected the release behavior of EVs in EVs-PLA microspheres. Scanning electron microscopy was used to detect the morphological changes of EVs-PLA microspheres at 8 weeks of release. EVs-PLA microspheres were co-cultured with hepatocytes, and Phalloidin/DAPI staining was used to observe the cell morphology and evaluate the cytotoxicity of the microspheres. CCK8-test was used to evaluate the cell proliferation activity. Western blot analysis was used to detect extracellular vesicles membrane marker protein expression. Results Comparing the ability of hepatocyte proliferation in the group treated with EVs-PLA microspheres and the control group, it was found that EVs-PLA microspheres did not cause cell apoptosis and mutation in cell structure, had biocompatibility and no cytotoxicity. The EVs-PLA microspheres with "core-shell" structure regulated the release behavior of EVs, which can continuously release EVs, exerting a continuous biological role in promoting hepatocyte proliferation after a single intervention. Conclusions The EVs-PLA microspheres can control-release EVs and promote hepatocyte proliferation continuously after a single intervention, providing a reference for further exploration of EVs-loaded delivery systems in promoting liver regeneration.

Objective To investigate the association of prevalence of periodontitis with metabolic syndrome (MS). Methods Data were analyzed from 1 650 Uygur rural residents in Moyu County. The subjects, aged over 18 years, were sampled randomly from 15 villages out of total 364 villages. Questionnaire, oral examination, and blood biochemical indicators were collected. The subjects were divided into groups with and without periodontitis based on chronic periodontitis diagnostic criteria, and the group with periodontitis was further divided into subgroups, each with mild, moderate, and severe periodontitis respectively. The diagnosis of MS was madeaccording to the definition of the International Diabetes Federation in 2005. Results Among 1 415 subjects whosedata were complete, there were 275 ( 19.4% ) subjects with MS and 934 (66.0%) subjects with periodontitis. The prevalence of MS was higher in the group with periodontitis than that without perionontitis (23.1% vs 12.3%, x2=23.9, P<0. 001 ). The prevalence of MS was increased with the grade of periodontitis, being 19.8%, 20.8%,27.6% in the mild, moderate, and severe periodontitis groups, respectively(x2= 31.9, P<0. 001 ). Multiple logistic regression analysis showed that the risk of MS increased with the grade of periodontitis, with OR 1. 6, 1.7,1.9, respectively, in the groups with mild, moderate, and severe periodontitis compared with that without perionontitis ( P<0.05 or P<0.01 ). Conclusions The prevalence of MS was related to periodontitis in the Uygur nationality and increased with the grade of periodontitis.

Objective To detect the circulating miR-106a levels in serum before and after surgery in patients with renal clear cell carcinoma,and to explore its relationship with clinical-pathological parameters.Methods 30 serum samples from patients with renal clear cell carcinoma were collected before and after surgery during February 2013 to July 2014.This study included 30 normal controls.All serum miR-106a levels were detected using the real-time PCR.Results The serum miR-l06a levels in patients with renal clear cell carcinoma pre-operatively wcre significantly greater than normal controls (Z =-4.251,P =0.0001).The serum miR-106a levels in patients post-operatively had no significant differences compared to normal controls (Z =-0.244,P =0.807).The serum miR-106a levels in post-operative samples were significantly lower than the pre-operative samples (Z =-4.229,P =0.0001).Serum miR-106a levels and other clinical-pathological parameters had no correlation in patients with renal clear cell carcinoma(tumor size:Z =-0.775,P =0.439;Fuhrman grade:Z =-1.694,P =0.090).The receiver operating characteristic curve was used to distinguish pre-operative samples and normal controls,its AUC was 0.819 (95％ CI:0.710-0.929,P =0.0001) with 86.7％ sensitivity and 70.0％ specificity.Conclusions The serum miR-106a levels in patients with renal clear cell carcinoma pre-operatively were significantly greater than post-operatively with no correlation in tumor size and Fuhrman grade.The outcome suggested that serum miR-106a can be regarded as a potential molecular marker in renal clear cell carcinoma.

BACKGROUND:Hair folicle stem cels have been confirmed to have stronger proliferative ability than interfolicular epidermal stem cels, which have been an issue of concern in seed cel research. OBJECTIVE:To compare the biological characteristics of rat hair folicle stem cels cultured by tissue explant method and enzymatic digestion method. METHODS: Under stereomicroscope, hair folicles were isolated from the rat whiskers, and then tissue explant method and two-step enzymatic digestion method were employed to culture hair folicle stem cels. Cels were purified using repeated differential adhesion method, and cel growth and morphology were observed periodicaly. Flow cytometry was used to detect the expression of CD34 and β1 integrin in passage 3 hair folicle stem cels. RESULTS AND CONCLUSION:Cels cultured by two-step enzymatic digestion method grew faster with more amount than those cultured by tissue explants method. Flow cytometry showed that the expressions of PE-CD34 and FITC-β1 were (39.52±19.57)% and (93.46±4.73)% for the two-step enzymatic digestion group, and (19.20±11.53)% and (363.57±14.42)% for the tissue explant method, respectively. There was a significant difference between the two methods. In conclusion, these two methods are able to culture high-activity hair folicle stem cels, which can be chosen according to different experimental requirements.
