Objective To observe the effect of neuromuscular electric stimulation (NMES) on post-stroke dysphagia (PSD). Methods Two hundred patients with swallowing dysfunction after stroke were randomly divided into a control group with 67 cases and a study group with 133 cases. All patients received pharmacotherapy and swal-lowing training. The study group also received NMES. The study group was sub-divided into unilateral and bilateral cortical stroke sub-groups, an ischemic stroke sub-group and a hemorrhagic stroke sub-group. The swallowing levels of the groups were compared after 2 courses of treatment with NMES. Results After an average of 20 days of NMES treatment, the level of dysphagia and its severity improved significantly. The patients with dysphagia due to unilateral stroke improved, on average, more than those with bilateral stroke. Patients with dysphagia due to ischemic stroke improved more than those with hemorrhagic stroke. Conclusions NMES therapy combined with rehabilitation train-ing can significantly improve swallowing in patients with PSD.

Objective To investigate the clinical characteristics, risk factors and prevention measures of carbapenem-resistant Klebsiella pneumoniae (CRKP) infection. Methods Thirty-nine cases whose CRKP isolation and culture were positive and who were confirmed with nosocomial infection in 2nd affiliated hospital medical school of Zhcjiang University between July 2006 and July 2008 were retrospectively investigated. Results There were 22 (56.4%) sputum specimens among CRKP samples. The average age of the patients was 64.0 years old and the average length of staying in hospital was 80.8 days. There wcre 36 patients who had been in intensive care unit (ICU) within 2 weeks and 26 were conscious disturbance,38 received urethral catheterization, 34 inserted with central venous catheter, 32 received tracheal intubation and 30 assisted with mechanical ventilation. There were 27 (69. 2 % ) patients who were co-infected with other bacteria and 8 were co-infccted with fungi. The mortality was 46. 2% in patients with CRKP infection. Before CRKP-positive culture, 27 (69.2%)experienced ＞4 kinds of antibiotics with the majority of β-lactams/β-lactamase inhibitors and carbapenems.Conclusions CRKP infection frequently occurrs in elder and patients who prolonged stay in hospital,especially patients in ICU. Invasive procedures could increase the infection opportunities.

Objective To investigate factors impacting on local recurrence in cases of primary retroperitoneal liposarcoma (RPLS) after complete enbloc resection.Methods The clinical data of 47 cases of primary retroperitoneal liposarcoma were retrospectively analyzed.Results 3-year local recurrence rate was 62％.Single and multiple regression analysis showed preoperative needle biopsy,histological subtype,tumor size and capsular invasion were all risk factors related to postoperative local recurrence in primary retroperitoneal liposarcoma undergoing complete resection (P ＜ 0.05).Conclusion Preoperative aspiration biopsy,tumor poor differentiation,large tumor size tumor extracapsular spread all lead to high local recurrence rate after complete resection of primary retroperitoneal liposarcoma.

BACKGROUND:Numerous experimental and clinical observations have shown new attachment formation in the periodontium by guided tissue regeneration. OBJECTIVE:To evaluate the efficacy of guided tissue regeneration combined with bone grafting for the treatment of root furcation defects. METHODS:A computer-based online search combined with manual retrieval was conducted up to 2015 to screen the relevant English and Chinese literatures addressing guided tissue regeneration, bone grafting, and root furcation defects. Vertical and horizontal probing depth and attachment loss were analyzed. Meta-analysis was performed using Stata/SE version 12.0 software by extracting data from the relevant articles. Moreover, the publication bias was tested. RESULTS AND CONCLUSION:The meta-analysis results showed that at 6 months after treatment, the alterations in vertical probing depth and periodontal attachment were significantly increased after guided tissue regeneration compared with open-flap debridement (P<0.000 01);the alterations and increment in the periodontal attachment were significantly increased after combined treatment of guided tissue regeneration and bone grafting compared with open-flap debridement (P<0.000 01);the reduction in the vertical and horizontal probing depth and the increment in periodontal attachment were significantly increased after combined treatment of guided tissue regeneration and bone grafting compared with guided tissue regeneration (P<0.000 01 or P=0.01). At 12 months after treatment, the reduction in vertical probing depth and the increment in attachment loss were significantly increased after combined treatment of guided tissue regeneration and bone grafting compared with guided tissue regeneration (P<0.000 01). These results indicate that the guided tissue regeneration combined with bone grafting in the treatment of root furcation defects is superior to guided tissue regeneration or open-flap debridement. In addition, in the latter two therapies, guided tissue regeneration shows a better therapeutic effect. However, the therapeutic effects of various types of regenerated membranes and bone grafts need further in-depth study to define the optimal treatment strategy.

Objective To determine the effect of apoptosis in different host cells induced by L. in- terrogans and the associated intracellular signaling pathway. Methods L. interrogans serogroup Icterohaem- orrhagiae serovar icterohaemorrhagiae strain Lai infected cell models in mouse mono-macrophage like cell J774A. 1, human EVC304 cells and A549 cells were established, respectively. Flow cytometry with fluores- cein labeling of FITC-Annexin V/PI was performed to examine the apoptosis or necrosis of the infected cells. Fluorometry as well as Western blot assay was applied to measure the activity of caspase-3, -8, -9 and the expression levels of apoptotic associated protein FADD in the infected cells , respectively . Results 36.70%-63.70% of the L. interrogans strain Lai infected J774A. 1 cells displayed obvious early apoptosis during the infection for 1-6 h, and then altered to later apoptosis / necrosis (53.68%) as the major injury pattern when infected for 12 h. 78.52% of the L. interrogans strain Lai infected A549 cells only showed later apoptosis / necrosis. However, no obvious apoptosis and / or necrosis could be found in the L. interrogans strain Lai infected EVC304 cells. The maximal activities of caspase-3 and -8 in the infected J774A. 1 cells were (1453.41±36.07) and (1402.15± 59.09) FU, respectively, which were the 16.38-fold and 29.99- fold of those the non-infected cells. The caspase-9 activity of the infected J774A. 1 cells slightly increased [(89.42±5.08) FU ], which significantly lower than those of caspase-3 and -8 (P <0.001). The FADD expression level of the infected J774A. 1 cells was gradually increased in an infection time-dependent man- ner. Conclusion There is a distinct diversity of apoptosis in different cells induced by L. interrogans, and FADD→caspase-8→caspase-3 is the major signaling pathway to mediate L. interrogans infection associated cell apoptosis.

BACKGROUND: It has been reported that nanosilver-containing biomaterials produce bad biological effects after they directly contact with or are implanted into human body.OBJECTIVE: To investigate whether nanosilver yields potential adverse biological effects on human body and to evaluate its bioiogical safety.DESIGN, TIME AND SETTING: An animal experiment observation was performed at the Medical Device Center of National Institute for the Control of Pharmaceutical and Biological Products from June 2005 to August 2006.MATERIALS: Nanosilver particles and microsilver particles were purchased from Sigma Company, USA.METHODS: Thirty rats were randomly divided into 3 groups, with 5 male and 5 female rats per group: nanosilver, microsilver, and blank control. Nanosilver and microsilver particles were respectively and subcutaneously implanted for subchronic toxicity test.The nanosilver and microsilver groups were given 0.33 g/kg nanosilver and microsilver, respectively. Rats from the blank control group received identical procedure, with the exception of drug application. Four rats were selected from each group for determination of silver content in serum and some organs by plasma mass spectrometry.MAIN OUTCOME MEASURES: serum biochemical indices, organ coefficient, and silver content.RESULTS: There was significant difference in individual organ coefficient between each drug application group and blank control group. But no significant difference in absolute mass was found between each drug application and the blank control group.These findings suggested no clinical significance of organ coefficient. Other organ coefficients were in the normal range, and there was no significant difference between each drug application group and the blank control group. Patho-histological changes related to toxicity were not found. Rats from the nanosilver group did not show toxic reaction.CONCLUSION: Nanosilver produces potential adverse biological effects after implanted into human body.
