The rehabilitation therapeutic method of dysphagia after stroke included movement therapy and compensatory technology (including neurodevelopmental therapy), neuromuscular electrical stimulation, surface electromygraphy biofeedback training, non-invasive brain stimulation, balloon ductal dilatation technique, acupuncture and moxibustion, drug, and surgical treatment. The movement therapy and compensatory technology were the basis of therapy and the upward and forward movements of tongue-throat complex were the core of therapy. The combined treatments of early, initiative, individual, and various methods were emphasized, while the nutrition and the preven-tion and cure of aspiration pneumonia of patients should be paid attention to.

Objective To systemically evaluate the quality of randomized controlled trials(RCTs) of recurrent oral ulcer(ROU) treated by traditional Chinese medicine.Methods The randomized controlled trials of TCM treatment on ROU were retrieved,and the related information from database was retrieved and assessed with Cochrane Handbook.Results Fifty-three articles in 41 journals were found.There were 12 diagnostic criteria and 8 effect criteria.Base-line comparision in 39 articles,blind methods in 3 articles,follow-up survey in 2 articles,adverse reaction in 10 articles,no case loss in all articles were reported.Conclusions The quality of RCTs of TCM for ROU should be improved.

AIM To investigate the effect of cisplatin on apoptosis in Scaber cell. METHODS The apoptotic cells were detected by TUNEL,HE,eletronic micrpscopy. RESULTS Treatment of Scaber cells with CDDP resulted in characteristics typical of apoptosis. CDDP induced apoptosis of Scaber cells in time and concentration dependent manner. To further investigate the mechanism of apoptosis induced by CDDP, the expressions and activity of apoptosis associated proteins such as bcl 2, bax and caspase 3 were examined using S P method.The results showed: CDDP caused time and concentration dependent decreases in bcl 2 and increased in bax proteins.CDDP bcl 2 and its translocation to perinuclei and nuclei. The expression of caspase 3 in Scaber cell were determined during apoptosis induced by CDDP. CONCLUSION Our investigetion showed that the apoptosis induced by CDDP is related to the increase of bax protein, and the decrease of bcl 2 protein. and its translocation to perinuclei and nuclei.

Objective To study the association of the expression of bone morphogenetic protein (BMP) antagonist gremlin and vascular calcification in radial arteries of patients with stage 5 of chronic kidney disease (CKD).Methods Radial arteries of 40 patients with stage 5 of CKD were collected as specimens of the study group,which were trimmed off during arterial venous fistula operations.Splenic trabecular arteries were collected as specimens of the control group,which were removed from 38 patients with simple traumatic splenic rupture.All the arteries were examined histologically for calcification with yon Kossa stain.Expressions of gremlin and BMP-2,-7were detected by immunohistochemistry and their serum concentrations were detected by ELISA.Images of histological sections were semi-quantitatively analyzed by Image-Pro Plus 6.0.SPSS 19.0software was used to perform statistical analysis.Results Significantly positive von Kossa stain was found in radial arteries from 12 of 40 patients (30％) in study group,which located in the layer of medial smooth muscle cells.However,there was no obvious positive stain in control group.Additionally,in study group,significant expressions of gremlin and BMP-2 were detected in those radial arteries of positive yon Kossa stain,which also located in the layer of medial smooth muscle cells.Positive correlations were found among gremlin expression level,BMP-2 expression level and yon Kossa stain intensity.However,the BMP-7 expression intensity in arteries of study group was much weaker as compared to control group.Conclusions Both gremlin and BMP-2 may be involved in the process that the smooth muscle cells of radial arteries in patients with stage 5 of CKD phenotypically transform into osteoblast-like cells.However,BMP-7 possibly prevents this process.

Objective To evaluate early diagnosis by gastroscopy for the causes of gastroduodenal perforation after successful non-surgical treatment.Method Gastroduodenal perforation patients suspected of benign ulcer in origin on hospital admission undergoing successful non-surgical treatment were examined by gastroscopy within days after the closure.Results Among 284 patients undergoing gastroscopy,277 cases (97.5％) were diagnosed as gastroduodenal ulcer,3 cases (1.1％) as gastric carcinoma,1 case (0.4％) of duodenal diverticulum.There were not major complications developing after gastroscopy.Conclusion Early gastroscopy performed after closure by non-surgical treatment in gastroduodenal perforation patients is safe,helping make definite diagnosis for the cause of perforation.

Impairment of neuronal mitochondria following hypoxia of brain not only result in nerve cell's energy-deprivation and dysfunction, mitochondria also play key roles in apoptosis of neurons. A central step being the release of cytochrome c (cyt c) across the outer mitochondrial membrane into the cytoplasm through opening of the mitochondrial permeability transition pore. Releasing of cytochrome c induce to downstream consequences of specific caspase activation. The antiapoptotic and proapoptotic members of the Bcl-2 family regulate mitochondrial activities relevant to apoptotic signaling by influencing the realaseing of cyt c.

OBJECTIVETo investigate the prevalence of Epstein-Barr virus (EBV)-associated gastric carcinomas in Guangzhou, their clinicopathologic features and related protein expressions including DNMT1, p16, and cyclin D1.

METHODA total of 676 cases of EBV-associated gastric carcinoma were included in the study. The presence of EBV-encoded small RNA1 (EBER1), a marker for EBV infection, was analyzed by in-situ hybridization using formalin-fixed and paraffin-embedded tumor samples. Expression of EBV-encoded proteins, DNMT1, p16 and cyclin D1 were detected by immunohistochemistry.

RESULTSForty-five of 676 gastric carcinomas showed EBER intranuclear positivity in all tumor cells. EBV involvement was significantly more frequent among the male than the female patients, especially in tumors of less differentiated types (diffuse type) and involving the upper stomach (P < 0.05). EBNA1 and LMP2A expression were detected in 42 (93.3%) and 24 (53.3%) cases, respectively. None expressed EBNA2, LMP1, and ZEBRA. Among 45 cases of EBV associated gastric carcinomas, DNMT1, p16 and cyclin D1 expression were seen in 35 (77.8%), 10 (22.2%), and 29 (64.4%) cases, respectively. In contrast, among 40 EBV negative gastric carcinomas, expression of the three proteins were 20 (50.0%), 25 (62.5%) and 12 (30.0%), respectively. The difference of expression of the three proteins between the two groups was significant (P < 0.05). Expression of p16 correlated with the depth of the tumor invasion. Correlated protein expression was seen between LMP2A and DNMT1, between DNMT1 and p16, and between p16 and cyclin D1 (P < 0.05).

CONCLUSIONSEBV associated gastric carcinoma accounts for 6.7% of gastric carcinomas in Guangzhou with the Latency I pattern in some cases and between Latency I and II in others. The correlated expression of LMP2A, DNMT1, p16 and cyclin D1 may contribute to the pathogenesis of EBV associated gastric carcinomas.
