1.Assessment of Activities of Daily Living for Patients with Chronic Obstructive Pulmonary Disease
Chinese Journal of Rehabilitation Theory and Practice 2009;15(5):414-415
Chronic obstructive pulmonary disease (COPD) influenced the activities of daily living (ADL) of COPD patients. The six-minute walking test is considered as a good marker of functional capacity to perform ADLs. However, it does not identify the activities roundly. A good ADL scale can be used to assess functional incapacity of ADL in patients with COPD, and present sensitivity to changes following pulmonary rehabilitation.

Objective To evaluated the preserving or removing jejunal mucosa pancreatico-jejunal invaginated anastomosis in pancreaticoduodenectomy.Methods Between February 2003 and December 2012,58 patients underwent pancreaticoduodenectomy using pancreaticojejunal invaginated anastomosis in our department.In group A,28 patients received pancreatico-jejunal invaginated anastomosis using jejunum preserving technique.Briefly,3 to 4 cm remanent pancreas was inserted into jejunum and thc jcjunum was bundled up using No.7 silk thread at 2 to 3 cm distant to the cutting surface of the pancreas.In group B,30 patients received pancreatico-jejunal invaginated anastomosis using jejunum removing technique.Briefly,the jejunum mucosa was everted and the proximal 3 cmlong mucosa was removed.Then the everted jejunum was re-positioned and the ending of the jejunum was interruptedly sutured to the remanent pancreas.Finally,the covered jejunum was tied up as the group A.Results The pancrcatico-jejunal anastomosis time was 36 ±0.34 minutes shorter in group A than group B (P <0.001).The incidence of pancreatic fistula was higher in group B (20.0%) than group A (0%).In contrast,the incidence of post-operative pancreatic bleeding was compared between the two groups (3.6% vs 3.3%,P =1.000).Conclusions Preserving ejunum mucosa pancreatico-jejunal invaginated anastomosis was unaffected by pancreatic texture pancreatic duct size and position.This method takes the advantages of simple operation and reducing the incidence of pancreatic fistula.

The ATP2C1 gene mutation in one case of familial benign chronic pemphigus was investigated. One patient was diagnosed as familial benign chronic pemphigus by pathology, ultrastructral examination and clinical features. Genomic DNA was extracted from blood samples. Mutation of ATP2C1 gene was detected by polymerase chain reaction (PCR) and DNA sequencing. The results showed that deletion mutation was detected in ATP2C1 gene in this patient, which was 2374delTTTG. No mutation was found in the family members and normal individuals. It was concluded that the 2374delTTTG mutation in ATP2C1 gene was the specific mutation for the clinical phenotype for this patient and was a de novo mutation.

ObjectiveTo investigate the safety and clinical value of treadmill exercise testing for the patients with acute myocardial infarction in the early recovery. Methods36 patients with acute myocardial infarction performed treadmill exercise testing with Bruce protocol 15~57 d after infarction. ResultsThe outcome of 19 cases was positive, and the outcome of other 16 cases was negative. 1 case couldn't finish the testing, whose outcome could not be analyzed because his exercise time was too short. The average cardic fuction was (5.42±3.12) METs. ConclusionIt is safe that the patients with acute myocardial infarction performed treadmill exercise testing early.

Abdominal withdrawal reflex (AWR) test, which evaluates the behavioral response of animals through expanding the intestinal tract, is the most widely used method to assess animal's visceral sensitivity in recent years.However, as AWR experimental operation involves many factors, it''s hard to find a commonly recognized operating procedure.Through review of literature of AWR experimental measuring methods, this article summarizes the basic steps of AWR operation.Meanwhile, it scrutinizes the differences of various measuring methods in relevant factors, including expansion method and airbag method, with special operating suggestions to them.Hopefully, this article will provide an option to future researchers who will use this method to evaluate animal''s visceral sensitivity, and provide a necessary foundation for the standardization of the experimental operation.

Objective To optimize the preparation of air bag materials for abdominal withdrawal reflex test.Methods To measure the diameters of different pressue-air bags by digital vernier caliper and X ray imaging.Using the pain threshold (3 points) as a criterion to test the pressure values of different air bags in the rats with corresponding visceral pain sensitivity.Results With the increasing pressure, the changes of the diameter of round latex balloon were uniform and gentle, and could meet the pressure range used in the experiment (20~80 mmHg).The threshold of visceral pain in rats was near the nociceptive stimulus value,and would not cause irreversible damage to the rat intestinal tract.Conclusions Air bag made from round latrex ballon is an ideal tool to be used in abdominal withdrawal reflex test in rats.

OBJECTIVETo investigate the effects of oral cancer-associated fibroblasts (CAFs) on lymphangiogenesis in oral squamous cell carcinoma (OSCC).
METHODSCAFs and normal fibroblasts (NFs) were obtained from the tissues of patients with OSCC who did not receive radio-chemotherapy before operation. And the CAFs and NFs were isolated by method of tissue block and identified by immunohistochemical staining. The effects of CAFs (group A) and NFs (group B) to human lymphatic endothelial cells (HLEC) were detected by using a 24-multiwell transwell cell culture chamber. DMEM sugar medium was as blank control group. The number of proliferative, migratory, invasive and tubes of HLEC were counted under inverted phase contrast microscope.
RESULTSThe proliferative number of HLEC of group A for 96, 144, 196 h was significantly higher than that of group B and blank control group, group B higher than blank control group (P<0.01). The migratory and invasive number of HLEC of group A for 96 h was significantly higher than that of group B and blank control group, group B higher than blank control group (P<0.01). The number of tube formation of HLEC of group A for 24 h was significantly higher than that of group B and blank control group, group B higher than blank control group (P<0.01).
CONCLUSIONCAFs promote HLEC's proliferation, migration, invasion, tube formation, and these effects are stronger than NFs.

As the research work went further and more detailed, a variety of new treatments compete to come out.However, it remains unclear that how the antigen works to distinguish cancer cells and normal cells.Neoantigen, which is located in the tumor cell surface of a specific antigen, its presence makes human immunotherapy into new areas which may make personalized treatment possible in the near future.Emerging data suggest that the identification of such newantigens is a major factor in clinical immunotherapy.They can form a biomarker in cancer immunotherapy to provide targets for a variety of therapeutic approaches to attack, which allows T cells to selectively enhance the immune response against this class of antigens.
