1.Bariatric surgery for the treatment of metabolic diseases
Chinese Journal of Digestive Surgery 2013;12(12):976-979
Bariatric surgery began in 1950s.The rapid increase of obese patients and development of laparoseopic techniques lead to popularity of bariatric surgery all over the world in 1990s.Current mainstream of bariatric surgeries include laparoscopic adjustable gastric banding,sleeve gastrectomy,Roux-en-Y gastric bypass and biliopancreatic diversion.In this review,the efficacy of different surgical procedures was compared in the aspects of metabolic disorder remission and incidence of operation complications and mortality.Efficacy of bariatric surgery on the alleviation of metabolic disorders (including hypergycemia,hyperlipidemia,hypercholesterolemia),individual treatment and interdisciplinary cooperation should be emphasized.
2.Isaacs syndrome:a case report
Chinese Journal of Rehabilitation Theory and Practice 2005;11(7):569-570
ObjectiveTo analyze the clinical features and pathogenesis mechanism of Isaacs syndrome.MethodsA case with Isaacs syndrome was reporttedResults and ConclusionIsaacs syndrome is characterized by the occurrence of spontaneous and continuous muscle fiber activity, associated with muscle cramps, pseudomyotonia and myokymia, stiffness and delayed relaxation of the muscle. The stiffness and myokymia are present at rest and during sleep. Isaacs syndrome has been recently suggested to be produced through an immune-mediated mechanism in which voltage-gated potassium channels may be targeted by auto-antibodies.

Objective To study the effect of CO2 pneumoperitoneum on migration of GFP-labeled living cells into the liver through blood route in rat model.Methods SD rats was inoculated intraportally with high-dose(5?106) GFP-labeled liver cells from C57BL/6 mice after cutting belly open.Pneumoperitoneum was established immediately after closing the abdominal wall.The rats were randomly divided into four groups(n=10 in each) to receive CO2 pneumoperitoneum at 5,10,or 15 mmHg,or no treatment other than cells inoculation(control).The pneumoperitoneum was maintained for 30 min.Afterwards,the rats were euthanized by cervical dislocation,and the liver of the rats was removed for fast frozen section biopsy.The expression of GFP-labeled living cells in rat livers was compared between the groups.Results No significant difference was detected in the positive expression of GFP-labeled cells between the groups(8 rats in the control group,9 in the 5 mm Hg group,9 in the 10 mm Hg group,and 10 in the 15 mm Hg group,?2=2.222,P=0.528).The mean number of GFP-positive cells in the four groups was 6.63?2.45(control),7.67?2.83(5 mm Hg),13.89?4.37(10 mm Hg),and 15.50?6.29(15 mm Hg).There was significant differences between the four groups(F=10.78,P=0.000).In addition,the numbers of GFP-positive cells in the high pressure groups(15 mm Hg and 10 mm Hg) were significantly higher than that in the low pressure group(5 mm Hg) and the control(P

Objective To identify the fungi isolated from two acute radiation sickness(ARS)patients as a result of an accidental 60Co irradiation,and to observe the sensitivity of the fungi to antifungal agents.Methods The pathogenic fungi were morphologically examined and identified with the VITEK 2 automatic microorganism analyzer and API 20C AUX yeast identifying card.The susceptibility of fungi to antifungal agents was tested with broth microdilution method.Results Candida parapsilosis and Sporothrix schenckii were identified from case A in the samples of blood,bone marrow,urine and stool etc.Most of pathogenic fungi were sensitive to the antifungal drugs in vitro.In case B,Candida parapsilosis,Candida tropicalis,Trichosporon asahii and Aspergillus terreus were identified in the samples of sputum,urine or stool etc.Accompanying with the prolongation of antifungal treatment,the sensitivity of fungi to the antifungal drugs were decreased remarkably.Conclusion Multiple infections in different organs could be caused by pathogenic fungi,such as Trichosporon asahii and Sporothrix schenckii.Although most of pathogenic fungi were sensitive to the antifungal drugs in vitro,the effects of antifungal treatment were not satisfactory owing to poor general conditions of 2 acute radiation sickness(ARS)patients and marked compromise of the immune system.Because of antibiotic and antifungal drugs were used early for preventive purpose,the clinical samples should be specially treated in order to raise the positive rate of fungal identification.

Objective To study the effect of Toll-like receptor 4(TLR4)on expression of IRF-3 and IFN-? during the inflammatory reaction induced by cerebral ischemia reperfusion in mice. Methods After blockade of TLR4 by TLR4 antibody,expression of TLR4,IRF-3 and IFN-? at the protein level in hippocampus was examined by Western blot,respectively. Mice were randomly divided into sham group,ischemia reperfusion group and TLR4 blocking group in different time points (1,2,3 and 4 day). Results In the right cortex,the expression of TLR4,IRF-3 and IFN-? of I group was distinctly higher than that of S and T group(P
8.EXPERIMENTAL STUDY OF PREPARATION OF AGAROSE BIOARTIFICIAL MICRO-CAPSULES
Chinese Journal of Endocrinology and Metabolism 1986;0(04):-
The permeability of three kinds of membranes, including imported agarose (Sigma), China-made agarose and interpenetrating polymer network (IPN) made of Chinese agarose mixed with other synthetic macromolecular compound, to four substances with different molecular weights (methyl orange, Vit B12 , insulin and lysozyme) was studied. The results revealed that the solutes with molecular weights below 6 000 dalton could permeate all kinds of membranes with similar coefficient of permeability. However, the immunoisolation of IPN for such macromolecular solute, as lysozyme (14 300 dalton) was much more effective than that of other kinds, which only had limited effect of immunoisolation. These results suggest that IPN with the characteristics of efficacious immunoisolation fulfills the requirements for transplantation. 2 000-3 000 microencapsulated islets were transplanted intraperitoneally in six diabetic rats without the use of immunosuppressive drugs. On the 4th post-operative day, blood sugar dropped significantly until the 7th day, when it was in normal range. The normal level of blood sugar had remained for 30 days. The microcapsules, made of IPN, possesses a better function of immunoisolation, which may lay a foundation of treating IDDM with encapsulated porcine islet grafting.

By using the high magnetic field spectrometer to assess the practical value of 1 H NMR spectroscopy in vivo through observation of changes in metabolism of C6 glioma, fourty Wister rats were divided into two groups: ten as controls, and in thirty rats C6 glioma cells were implanted spheroids in right caudate nucleus. MR images were carried out at intervals. The 1 H NMR spectroscopy were performed by using point resolved spectroscopy (PRESS) technique. The NAA Cho, Cr+PCr, Glu+Gln, Lip, Lac were observed in normal rats. The NAA intensity was seen to be decreased or disappeared in C6 glioma, and NAA/Cho ratio and NAA/Cr ratio decreased obviously( P

To investigate the change in GMP 140 and its significance in patients with diabetes accompanied with cerebral infarction. Plasma GMP 140 levels were assayed by radilimmunoassay in diabetes accompanied with cerebral infarction, controlled diabetes, cerebral infarction patients and normal controls, respectively. The results showed the GMP 140 levels were significantly higher in patients with diabetes accompanied with cerebral infarction than in patients with diabetes and normal control ( P 0 05). The results suggested that the level of GMP 140 in plasma might be used as a sensitive and reliable indicator reflecting the degree of platelet activation.
