Objective:To detect the anti-cancer component, trans-resveratrol in red wine by high performance liquid chromatography, and to determine the influence of environmental factors on its content. Methods: A method for determining trans-resveratrol in red wine by HPLC is described. The operating conditions were ZORBAX-C18 column(4.6 mm×250 mm, 5μm) at room temperature, 30%acetonitrile as mobile phase at a flow of 1ml/min and UV detection at 306 nm. Results:The content of trans-resveratrol in Changyu dry red wine and Great Wall Claret Cabernet are (1.01±0.03)mg/L and (2.36±0.02)mg/L, respectively. The results show that, sunlight, high temperature and poor seal condition can decrease the content of trans-resveratrol. Conclusion:The content of trans-resveratrol varies in different brands of red wine. Red wine should be stored in cool, dark and sealed conditions.

Minor stroke is characterized by the mild symptom and rapid recovery,and does not easily cause disability,but a part of patients with minor stroke are the high risk population of recurrent stroke,and can cause disability,cognitive impairment,and emotional disorders.Early prediction of the prognosis in patients with minor stroke,screening for the high risk population of recurrent stroke and disability,and giving appropriate treatment may prevent recurrent stroke and improve the prognosis of patients.This article reviews the predictors of prognosis in patients with minor stroke.

Objective To summarize our experience on the treatment for severe vascular injuries in the operation of great saphenous varicose vein. Methods The clinical data of 4 cases (5 lower limbs) from December 2004 to April 2009 of severe vascular injuries were retrospectively analyzed. For the lower limbs in which from the end of femoral artery to the upper part of posterior tibial artery were stripped, reconstruction operation using blood vessel prothesis was performed, above knee amputation was performed because of limb gangrene. For three limbs in which 10 cm to 15 cm superficial femoral artery were stripped, reconstruction operation using autologous saphenous vein were performed, above knee amputation was performed for one limb 5 days after the operation. For the limb in which 2 cm superficial femoral vein were cut, reconstruction operation using autologous saphenous vein were performed. Results No cases died perioperatively,for four limbs of injuried artery, ampution were performed for two limbs(50% ) ;two limbs (50%) were saved. The patient of injuried superficial femoral vein recovered. Conclusions Severe vascular injuries can be prevented and its incidence reduced by improving the awareness for iatrogenic vascular injuries,accurate operation; once the vascular injury occurred, prompt and rational measures must be adopted.

Objective To investigate the clinical characteristics,diagnosis and treatment for Graves' disease associated with papillary thyroid microcarcinoma(PTMC) by retrospectively analyzing domestic and foreign literatures.Methods 32 patients of Graves' disease associated with PTMC treated at the Department of Thyroid Surgery,the First Bethune Hospital of Jilin University from Jun.2008 to Jun.2013 were collected.32 cases of PTMC with normal thyroid function were randomly selected by a random number table method from the same period as control.Results The experimental group had 32 patients aging from 24 to 71 years old,among whom 3 were males,and 29 were females with the male to female ratio was 1∶9.7.15 cases in the experimental group had positive central lymph node metastasis and the other 17 cases were negative,while in the control group 7 cases were positive and 25 cases were negative.The mean number of positive lymph nodes was 3 ± 2.88 in the experimental group and 1.71 ± 1.25 in the control group.The ratio of positive lymph node metastasis(the number of positive lymph nodes/the total number of lymph nodes,and the total number of central lymph nodes was ＞3)was (50.34 ±27.09) ％ in the experimental group and(33.5 ±30.79)％ in the control group.For the above 3 values of central lymph node metastasis,the experimental group were all higher than those of the control group (P =0.035,0.039,0.018 respectively).Conclusions Compared with patients of PTMC,patients of Graves' disease associated with PTMC are more likely to have central lymph node metastasis,more number of positive lymph node and higher metastasis ratio.In order to prevent the postoperative recurrence of Graves' disease and thyroid carcinoma local lymph node,total thyroidectomy plus central lymph node dissection should be the ideal operation method.

Leucine zipper tumor suppressor 2 (LZTS2) is a novel tumor suppressor gene that has been increasingly recognized in recent years. Currently, many studies illustrate that LZTS2 gene, the important candidate tumor suppressor gene, is already involved in the inhibition of tumorigenesis and aberrant proliferation of tumor cells, and other functions of tumor cells. Information from these stud-ies can contribute to the formulation of new strategies for the treatment of tumors.

BACKGROUND:Chitin has been found to be a good biomaterial, but research on chitin carrying corneal epithelial cel s for rabbit corneal epithelial injury is little reported. OBJECTIVE:To investigate the repair outcomes of chitin hybrid membrane carrying corneal epithelial cel s in the rabbit corneal epithelial injury.METHODS:Eighteen New Zealand white rabbits were enrol ed and made into left corneal epithelial injury models, and then randomized into two groups and treated with chitin hybrid membrane carrying corneal epithelial cel s (experimental group) and chitin hybrid membrane (control group), respectively. The damage area, histological changes and ultrastructure of the cornea were observed at 1, 3, and 7 days after implantation. RESULTS AND CONCLUSION:Damage area of the cornea in the experimental group was significantly less than that in the control group at 1 and 3 days after implantation (P<0.05), and the cornea in both two groups healed wel at 7 days after implantation. At 7 days after implantation, in both two groups, the corneal epithelium with six layers adhered to the corneal stroma closely, which was repaired completely and regularly. Comparatively speaking, the cornea in the experimental group possessed smooth outer layer. Besides, in the experimental group, the hexagonal corneal epithelial cel s arranged closely with flat surface;while the hexagonal corneal epithelial cel s in the control group showed no smooth surface and gaps between cel s. These results indicate that chitin hybrid membrane carrying corneal epithelial cel s promotes the repair of rabbit corneal epithelial injury.

BACKGROUND:Chitosan nanoparticles-encapsuled sodium hyaluronate is an effective drug for the burned cornea. OBJECTIVE:To verify the effect of sodium hyaluronate/chitosan nanoparticles on the neovascularization in burned cornea. METHODS:Thirty Sprague-Dawley rats were randomly divided into three groups, and the model of burned cornea caused by base was established in the rats of model and experimental groups, fol owed by respectively treated with 10μL sodium hyaluronate/chitosan nanoparticle suspension and normal saline, once daily, for consecutive 4 weeks. Rats only given normal saline were used as controls. Four weeks later, the dynamic growth of newly formed blood vessels in the cornea was observed using silt lamp. The levels of tumor necrosis factor-αand interleukin-6 were detected by ELISA, histological changes of the cornea were observed by hematoxylin-eosin staining, and the mRNA expression levels of vascular endothelial growth factor and cyclooxygenase 2 were detected by real-time PCR. RESULTS AND CONCLUSION:Compared with the control group, the area of the newly formed blood vessel and the levels of tumor necrosis factor-α, vascular endothelial growth factor and cyclooxygenase 2 were significantly increased in the model group (P<0.05, P<0.01). In the experimental group, al above indicators were significantly lower than those in the model group (P<0.05). There were a large number of inflammatory cel s and neovascularization in the model group, but only few inflammatory cel s in the experimental group. These results show that sodium hyaluronate/chitosan nanoparticles can inhibit the neovascularization in the burned cornea.

Objective To observe the efficacy in combination with Hemp seed pill and lactulose oral solution for treating cancer pafients with constipation induced by morphine-type drugs.Methods 62 Cancer patients with constipation induced by morphine-type drugs diagnosed by pathology or cytology were collected from January 2013 to July 2016 in Suzhou BenQ hospital for this study.The patients in study group received both Hemp seed pill and lactulose oral solution, and patients in control group received lactulose oral solution only.After treatment for 3 weeks,some indexes were observed, including outcomes in the overall response rates, Karnofsky score, weight.Results The total effective rate of the study group was higher than the control group(77.4%vs 48.3%, P<0.05), the difference was statistically significant;After treatment,Karnofsky score and the percentage of patients gaining weight in study group were markedly higher than those in control group,the difference was statistically significant(P<0.05).Conclusion Hemp seed pill combined with lactulose oral solution has a good clinical efficacy in treating pafients with constipation induced by morphine-type drugs, and can improve patient's quality of life.

Objective To explore the effect of chronic intermittent hypoxia (CIH) on hippocampus neuron and growth associated protein-43 (GAP-43) in rats. Methods 40 adult male Sprague-Dawley rats were randomly divided into control group, CIH 1 week group, CIH 3 weeks group and CIH 5 weeks group with 10 rats in each group. The CIH groups were exposed to intermittent hypoxia in designed cabin 8 hevery day for 1 week, 3 weeks and 5 weeks. The pathological changes of hippocampal neurons were observed by HE staining. The GAP-43 expression of hippocampus was detected by immunohistochemical staining. Results There was degeneration and necrosis of hippocampal neurons in the CIH rats, and it became worse gradually along with the hypoxia. Compared with the control group, the GAP-43 expression in hippocampus increased in CIH rats. The peak of GAP-43 expression appeared in the 1st week (P=0.038) and then it decreased in the 3rd week (P=0.382) and it was closed to the normal level in the 5th week (P=0.860). Conclusion Degeneration and necrosis of hippocampal neurons exacerbated gradually along with the hypoxia, while GAP-43 expression changed inconsistently.

In recent years the interaction between host and gut microbiota has attracted increasing attention. However, intestinal flora dysbiosis may lead to many diseases, and there is increasing evidence that the intestinal microbiota in patients with chronic kidney disease (CKD) is associated with the pathophysiological status of the host. "Gut-kidney axis" provides a better explanation of the two-way communication between intestinal flora and CKD. Impaired kidney function leads to dysbiosis of intestinal flora and an altered intestinal flora can damage the intestinal mucosal barrier and facilitate the entry into the bloodstream of harmful bacteria, which can induce chronic inflammation and thus accelerate renal injury. In addition, the accumulation of nephrotoxic metabolites from an altered intestinal flora can aggravate CKD in the "gut-kidney axis". Among them, p-cresol sulfate, indoxyl sulfate and trimethylamine oxide are the most widely studied metabolites of nephrotoxicity, and their renal toxicity has been widely confirmed in basic research and clinical studies. Current studies show that the intestinal microbiota-metabolite network is closely related to the occurrence and development of chronic kidney disease. Thus, intervention in the intestinal microbiota may provide a new approach to the prevention and treatment of chronic kidney disease.
