Objective To investigate the efficacy of autologous peripheral hematopoietic stem cell transplantation in the treatment of adult dermatomyositis. Methods A 21-year-old patient with dermatomyositis received autologous peripheral hematopoietic stem cell transplantation and was followed up for 6 years. Autologous peripheral hematopoietic stem cells were mobilized by recombinant human granulocyte colony stimulating factor (rhG-CSF) before the transplantation, and the conditioning regimens consisted of cyclophosphamide,methylprednisolone and cyclosporin. Rabbit anti-human T lymphocyte immunoglobulin began to be applied on day 3 after retransfer of stem cells. The improvement in symptoms, physical signs and biochemical indicators was observed, and hematopoietic restructuration and immunity resurrection were evaluated after the transplantation. Results After the transplantation, skin eruption greatly improved and gradually subsided. The muscle force of extremities restored from level Ⅳ before transplantation to level Ⅴ. The level of creatine kinase declined sharply after transplantation, but gradually returned to previous level. Leucocyte count began to decrease on the day of retransfer, and returned to the normal level on day 8. Immune function remained normal before and after the transplantation. Conclusion Autologous peripheral hematopoietic stem cell transplantation is an alternative treatment for severe and refractory dermatomyositis.

Objective To investigate the effect of autophagy in radiosensitivity of nasopharyngeal carcinoma CNE-2 cells.Methods The expression of ATG5 in CNE-2 cells was inhibited by lentiviral mediated RNA interference.The cells were divided into three groups:control group,NC group and ATG5 group.Cell proliferation,apoptosis and radiosensitivity were detected by CCK-8 method,flow cytometry and colony-forming assay,respectively.Results Compared with the NC group and control group,the survival of ATG5-interfected cells was reduced (F =3.755,46.086,8.609,44.160,P ＜ 0.05).After 6 Gy X-ray irradiation,the apoptosis index of the ATG5 group significantly higher than that of NC group and control group (F =394.876,P ＜ 0.05).In addition,the radiosensitivity of ATG5 group was also higher than that of control cells.Conclusions Suppression of autophagy activity enhances the radiosensitivity of human nasopharyngeal carcinoma cells.

Objective To investigate the effect of different sealing methods of urokinase plus heparin on long-term dialysis catheter thrombolysis.Methods63 patients were treated with maintenance hemodialysis from central venous catheters with catheter thrombosis as a clinical study.The patients were divided into observation group and control group by simple random method.In the observation group, 31 cases were treated with urokinase and heparin mixed solution from the ends of the arteriovenous catheter of permanent double-laryngeal dialysis tube for 24 hours for 3 consecutive days.32 patients in the control group, from the permanent dual-chamber dialysis catheter arterial and vein at both ends with a micro pump pumped urokinase, maintained for 2hours.ResultsThere was no significant difference in thrombolytic success rate between the two groups.The catheter retention time in the observation group was significantly longer than that in the control group, the dialysis blood flow rate, the solute clearance index and the urea clearance index were significantly higher than those in the control group.The incidence of venous pressure and hemorrhagic adverse events was significantly lower than that of the control group (P<0.05).ConclusionUrea kinase plus heparin mixture is simple and easy to operate, which avoids the risk of excessive localized or systemic hemorrhage caused by excessive urokinase into the blood circulation of patients.It is worthy of popularization.

The non-neuronal cholinergic system, widely exists in prokaryotic, eukarytic, and even plant cells, however, it has not been investigated in preadipocytes and adipocytes. To search for evidence its existence in preadipocytes and adipocytes, the nicotinic acetylcholine receptor (nAChR) α7 subunit, acetyicholinesterase (ACHE) and choline acetyltransferase (CHAT) in 3T3-L1 cells were examined using immunohistochemical staining and Western blotting. The choline-regulated visfatin expression in 3T3-L1 preadipocytes was also tested by reverse transcriptase-PCR. Incubation with methyilycaconitine (10-6 to 10-4mol/L) for 12, 24 and 36 hours dose-dependently increased visfatin expression from 1.3- to 1.55-folds (P <0.01) with maximal induction at 24 hours with 10-4mol/L methyllycaconitine. Nicotine treatments (10-6 to 10-4 mol/L) for 12, 24 and 36 hours decreased visfatin expression; choline chloride (10-4 mol/L))suppressed visfatin expression in 3T3-L1 preadipocytes at 36 hours by 1.64 to 2.03 fold (P < 0.05) which was more effective as compared with nicotine. It was concluded that α7 nAChR was expressed in 3T3-L1 preadipocytes and involved in visfatin expression.

Nitrites play multiple characteristic functions in invasion and metastasis of hepatic cancer cells, but the exact mechanism is not yet known. Cancer cells can maintain the malignant characteristics via clearance of excess mitochondria by mitophagy. The purpose of this article was to determine the roles of nitrite, reactive oxygen species (ROS) and hypoxia inducing factor 1 alpha (HIF-1 α) in mitophagy of hepatic cancer cells. After exposure of human hepatocellular carcinoma SMMC-7721 cells to a serial concentrations of sodium nitrite for 24 h under normal oxygen, the maximal cell vitality was increased by 16 mg x (-1) sodium nitrite. In addition, the potentials of migration and invasion for SMMC-7721 cells were increased significantly at the same time. Furthermore, sodium nitrite exposure displayed an increase of stress fibers, lamellipodum and perinuclear mitochondrial distribution by cell staining with Actin-Tracker Green and Mito-Tracker Red, which was reversed by N-acetylcysteine (NAC, a reactive oxygen scavenger). DCFH-DA staining with fluorescent microscopy showed that the intracellular level of ROS concentration was increased by the sodium nitrite treatment. LC3 immunostaining and Western blot results showed that sodium nitrite enhanced cell autophagy flux. Under the transmission electron microscopy (TEM), more autolysosomes formed after sodium nitrite treatment and NAC could prevent autophagosome degradation. RT-PCR results indicated that the expression levels of COX I and COXIV mRNA were decreased significantly after sodium nitrite treatment. Meanwhile, laser scanning confocal microscopy showed that sodium nitrite significantly reduced mitochondrial mass detected by Mito-Tracker Green staining. The expression levels of HIF-1α, Beclin-1 and Bnip3 (mitophagy marker molecular) increased remarkably after sodium nitrite treatment, which were reversed by NAC. Our results demonstrated that sodium nitrite (16 mg x L(-1)) increased the potentials of invasion and migration of hepatic cancer SMMC-7721 cells through induction of ROS and HIF-1α mediated mitophagy.

OBJECTIVETo evaluate the efficacy and safety of Yigan Fupi Decoction (YFD) in the treatment of irritable bowel syndrome with diarrhea (IBS-D) patients.

METHODSA randomized controlled clinical trail was carried out in patients with IBS-D. All patients were randomly assigned to the treatment group (58 cases, treated with YFD) and the control group (58 cases, treated with Pinaverium Bromide Tablet). The treatment course was 4 weeks for all patients. The total effective rate, the stool property and state, the quality of life (QOL), and TCM syndrome efficacy were assessed by IBS bowel symptom severity scale (IBS-BSS), IBS defecation state questionnaire (IBS-DSQ), IBS quality of life questionnaire (IBS-QOL), and traditional Chinese medicine pattern curative effect scoring system (TCM-PES) before and after treatment.

RESULTSThere was no statistical difference in the total effective rate between the two groups (82.76% vs. 77.59%, P > 0.05). The treatment group was superior in the total IBS-BSS integral to the control group (P < 0.05). The total effective rate of improving the stool property was better in the treatment group than in the control group (81.03% vs. 72.41%, P < 0.05). Besides, the number of days for emergent defecation among 10 days was less in the treatment group than in the control group (P < 0.05). The improvement of the total IBS-QOL integral and the total integral of TCM syndrome were better in the treatment group than in the control group (P < 0.01). The total effective rate of TCM-PES was better in the treatment group than in the control group (84.48% vs. 70.69%, P < 0.05).

CONCLUSIONYFD was effective in the treatment of IBS-D patients of Gan-qi invading Pi syndrome, and could effectively relieve bowel symptoms, improve the stool property and the defecation frequency, elevate their QOL, and attenuate Gan-qi invading Pi syndrome with favorable safety and compliance.
