Objective The aim of this article is to study the clinical features, image, electroencephalogram and gene mutation of mitochondrial encephalomyopathy with MELAS and to improve understanding of the disease. Methods Clinical data was collected from 12 MELAS cases. Their clinical symptoms, head imageological result,electroencephalo-gram and gene mutation were analyzed. Results The average onset age was 28 years old. The main manifestations of 12 patients were epilepsy(66.7%), stroke-like episodes(50.0%), mental behavious disorder and decrease of perceive (41.7%),diabetes or abnormal glucose tolerance(41.7%), hearing impairment(41.7%). The imaging results showed long T1, long T2 and high signals on DWI. The nidus involved occipital lobe, temporal lobe, parietal lobe most. Five of six cases undergoing MRS imaging had large lactate peak at 1.33 ppm. There were 9 cases carrying mtDNA A3243G muta-tion. Conclusion The clinical presentation of MELAS is highly variable without any obvious specificity on MRI and EEG. Large lactate peak on MRS may indicate the disease. Most patients carry A3243G mutation.

Objective To evaluate and verify the preventive and therapeutic effects of electroacupuncture (EA) plus pelvic floor muscle training (PFMT) in treating mild-moderate female stress urinary incontinence (SUI). Method By adopting a single-blind randomized controlled design, eighty-two SUI patients were randomized into an observation group of 40 cases and a control group of 42 cases. The observation group was intervened by EA plus PFMT, while the control group only received PFMT. Before the treatment and after 4-week treatment, the 1 h urine leakage amount, Incontinence Questionnaire Short Form (ICI-Q-SF) and improvement rate were evaluated in the two groups, to analyze the effects of the two methods in improving mild-moderate SUI. Result For mild SUI patients, the 1 h urine leakage amount and ICI-Q-SF score dropped significantly after the treatment in the observation group (P<0.05), and the observation group was significantly lower than the control group (P<0.05). For moderate SUI patients, the 1 h urine leakage amount and ICI-QSF score dropped significantly in both groups after the intervention (P<0.05), the observation group was significantly lower than the control group (P<0.05), and the improvement rate in the observation group was markedly higher than that in the control group (P<0.01). Conclusion EA plus PFMT caneffectively improve the urine leakage and urination in mild-moderate SUI patients. EA plus PFMT can effectively prevent the aggravation of moderate female SUI, and its effect is better than PFMT alone.

ObjectiveTo explore the effect of doctor-nurse integration mode in treating patients with liver cirrhosis treated with endoscopic variceal ligation (EVL).Methods According to the random number table,74 patients were randomly divided into control group and experiment group with 37 in each group.The control group was given routine nursing,while the experiment group was managed by doctor-nurse integration nursing mode.The two groups were compared in respect of early re-bleeding after EVL and mastery of health knowledge.Result The mastery of health-related knowledge in the experiment group was better than the control one and the rate of re-bleeding was significantly lower (P<0.05).Conclusion The doctor-nurse integration care mode can reduce the early postoperative re-bleeding after EVL in patients with liver cirrhosis and enhance the health education awareness.

Abstract?AlM:To evaluate the accuracy and practicability of three - dimensionally preformed Arbeitsgemeinschaft Osteosynthese AO titanium mesh plates for orbital fractures.?METHODS:Forty-seven patients with isolated blow-out orbital fractures were included in this study. Fracture locations were as follows: floor/medial wall ( n = 26, 55%), medial wall ( n = 12, 26%), and floor ( n = 9, 19%) . The floor fractures were exposed by a standard transconjunctival approach, whereas a combined transcaruncular transconjunctival approach was used in patients with medial wall fractures with temporary dissection of inferior oblique muscle. A three -dimensionally preformed AO titanium mesh plate was selected according to the size of the defect previously measured on the preoperative computed tomographic scan examination and fixed at the inferior orbital rim with 2 screws. The accuracy of plate positioning of the reconstructed orbit was assessed on the postoperative computed tomography ( CT) scan. The practicability of clinical use of AO three - dimensionally preformed titanium mesh plates was assessed on the preoperative and postoperative clinical data.?RESULTS: Postoperative orbital CT scan showed an anatomic three- dimensional placement of the orbital mesh plates in all of the patients. All patients had a successful treatment outcome without clinical complications. 40 patients ( 87%) had a successful enophthalmos correction. 25 patients ( 86%) had a successful recovery from diplopia.?CONCLUSlON: Three- dimensionally preformed AO titanium mesh plates for orbital fracture reconstruction results in an accurate anatomic restoration of the bony orbital contour with a high rate of success to correctenophthalmos and diplopia.

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.

This study was purposed to investigate the effect of 3'-azido-2', 3'-dideoxythymidine (AZT)on the proliferation and telomerase activity of human acute myeloid leukemia cell line KG-1a. The effect of proliferation was detected by MTT assay after the KG-1a cell were stimulated for 24, 48 and 72 h with different concentrations of AZT; telomerase activity was detected with TRAP-PCR-ELISA assay; RT-PCR was used to detect telomerase hTERT mRNA expression. The results showed that the proliferation of KG-1a cells was inhibited in a time and concentration dependent manner after exposure to AZT for 24, 48 and 72 h; the KG-1a cells decreased in S phase and increased in G(2)/M phase with the increasing of the concentration of AZT; telomerase activity and hTERT-mRNA expression in the experimental groups decreased after treated with AZT, which was positively correlated with concentration of AZT. It is concluded that AZT inhibits KG-1a cell proliferation and induces apoptosis, which maybe related with its decreasing the telomerase activity and hTERT mRNA expression.

Objective:To observe the changes in percentages and subsets of invariant nature kiler T (iNKT) cells in adipose and related tissues at different stages of obesity, and analyze the role of iNKT cells during chronic inflammation in adipose tissues in a mouse model of obesity established with high-fat diet.Methods:Changes in mouse body weight, mental state, glucose tolerance and insulin tolerance were recorded. Hematoxylin and eosin (HE) staining was used to observe pathological changes in adipose tissues. Flow cytometry was performed to detect the percentages and subsets of iNKT cells as well as the percentages and subtypes of macrophages. The levels of cytokines in serum samples and the culture supernatants of lymphocytes in adipose tissues were detected with CBA. The expression of related proteins in adipose tissues was detected by Western blot.Results:(1) The volume of adipose cells increased significantly after four weeks of high-fat feeding, but the infiltration of inflammatory cells was not obvious. Significantly increased infiltration of inflammatory cells was observed after 12 weeks of high-fat feeding. (2) High-fat feeding could reduce the percentage of iNKT cells, increase the proportion of iNKT1 subgroup and decrease the proportion of iNKT10 subgroup in adipose tissues. The proportion of iNKT1 subgroup in thymus increased, but that of iNKT2 subgroup decreased. The percentage of macrophages and the proportion of M1 subgroup in adipose tissues increased, while the proportion of M2 subgroup decreased, which were more obvious after 12 weeks of high-fat feeding. (3) High-fat feeding resulted in decreased expression of E4BP4 and arginase-1 (Arg-1) in adipose tissues and increased expression of inducible nitric oxide synthase (iNOS). (4) High-fat feeding significantly increased the pro-inflammatory cytokines and decreased the anti-inflammatory cytokines in mouse serum and culture supernatants of lymphocytes in adipose tissues with more significant changes observed after 12 weeks of high-fat feeding.Conclusions:Increased iNKT1 and decreased iNKT10 in obese adipose tissues might be closely related to the increased M1 polarization and the imbalance of iNKT subsets might be involved in the progression of chronic inflammation in obese adipose tissues.

BACKGROUND: Similar to other prosthesis, metal-metal prosthesis would produce plenty of wear particles and metal ions, mainly presented as cobalt (Co~(2+)) and chromium (Cr~(3+)), which can lead to osteolysis, eventually, result in aseptic loosening. OBJECTIVE: To observe the effect of Co~(2+) and Cr~(3+) ions on the cells viability and expression of RANK in rats m0nocyte-macrophage cells (RAW264.7) in vitro. METHODS: Monocyte-macrophage cells (RAW264.7) were cultured in vitro, and then the cells were exposed to Co~(2+) and Cr~(3+) ions. The cell viability was assured by MTT test and the level of RANK Mrna was detected by semi-quantitative RT-PCR at different times. RESULTS AND CONCLUSION: Compared to the control group, MTT test demonstrated that Co~(2+) and Cr~(3+)ions could decrease the cell activity of monocyte-macrophage cells obviously. When the cells were exposed to Co~(2+) Cr~(3+) ions, compared to the control group, the Mrna expression of RANK of the metal ions group was increased at 12 hours (P < 0.05), reached its peak level at 24 hours (P < 0.05), and decreased at 48 hours than that of 24 hours (P < 0.05). The results revealed that metal ions have a cytotoxic effect on monocyte-macrophage cells, stimulate the expression of RANK, and have the potential of facilitating monocyte-macrophages cells transform into osteoclast-like cells.
