Objective To investigate the galectin-3 expression in squamous carcinioma of esophagus and analyze its relationship with clinicopathological characteristics.Methods S-P immunohistochemistry was used to detect the expression of galectin-3 in 80 paraffin-embedded specimens of esophageal carcinoma and 22 specimens of normal tissues adjacent to the benigh lesions of esophagus.RT-PCR was performed to detect galectin-3 mRNA expression in 36 pairs of fresh squamous carcinoma tissues and corresponding adjacent normal mucosa.Results Out of 80 specimens of squamous carcinoma of esophagus,62 specimens had positive expression of galectin-3,with the positive rate of 77.5%(62/80)that was significantly higher than 27.27% in normal esophageal tissues(6/22,P

To analyse the relationship between tumor necrosis factor (TNF)-α and interleukin-6 with hyperuricemia in ethnic Uygur,Kazak,and Han in Xinjiang province.1 200 cases of Uygur,Han,and Kazak populations were randomly enrolled.Serum uric acid,triglyceride,total cholesterol,high density lipoprotein-cholesterol,low density lipoprotein-cholesterol,fasting plasma glucose,body weigh and height,waist circumference,and hip circumference were measured.Waist-to-hip ratio and body mass index were calculated,and TNF-α,interleukin-6 were determined.The differences between uric acid and inflammatory factors were statistically significant; The differences in TNF-α was statistically significant between high uric acid group and control group in Uygur and Han,and the differences in interleukin-6 was statistically significant between high uric acid group and control group in Uygur,Kazak,and Han(P＜0.01).TNF-α and interleukin-6 were positively correlated with serum uric acid in Uygur,but in Kazak only interleukin-6 was negatively correlated with serum uric acid,in Han only interleukin-6 was positively correlated with serum uric acid(P ＜ 0.01).Hyperuricemia was associated with inflammatory factors,TNF-α,interleukin-6,but there were ethnic differences among Uygur,Kazak,and Han,thus it may provide people of new ideas for prevention and treatment of hyperuricemia and other related metabolic disorders.

Objective To respectively analyze the patterns and possible predictors of recurrent strokes among patients with initial ischemic stroke.Methods Three hundred and sixty-one patients with recurrent strokes (acute ischemic stroke or intracerebral hemorrhage) after initial ischemic strokes were collected from Jan 2004 to Dec 2009.The data about conventional risk factors such as smoking,heavy alcohol drinking,hypertension,diabetes,hyperlipidemia,heart diseases,head trauma,migraine,family history of cardiovascular disease,and the use of preventive medications were collected and analyzed among patients with different types of recurrent strokes.Results Patients (n =361) were divided into ischemic stroke group (n =321) and hemorrhagic stroke group (n =40) according to the recurrent stroke type.The ischemic stroke group was further divided into the anterior circulation stroke subgroup (n =234),the posterior circulation stroke subgroup (n =75) and watershed cerebral infarction or multiple infarction subgroup (n =12).Multivariate logistic regression analysis revealed that older age at initial stroke onset (OR =1.036,95 ％ CI 1.006-1.067,P =0.02) and hyperlipidemia (OR =2.253,95 ％ CI 1.092-4.647,P =0.028) were both the independent risk factors for the recurrent ischemic stroke.Comparing the subgroups,multivariate logistic regression analysis showed that atrial fibrillation (OR =4.217,95％ CI 1.489-11.942,P =0.007) was the independent risk factor for the recurrent ischemic stroke in the posterior circulation territory.Conclusion Aging and hyperlipidemia are possible predictors of recurrent ischemic stroke after the initial ischemic stroke which would be useful for individualized secondary prevention of stroke.

The heterogeneity of high-density lipoprotein-cholesterol (HDL-C) in hyperuricemia was analyzed in Uygur,Han,and Kazak ethnic groups in Xinjiang.A total of 2 396 subjects were surveyed.The HDL-C levels were significantly decreased in hyperuricemia group compared with control group in Han and Uygur,while the reverse occurred in Kazak.The serum uric acid (SUA) level in Kazak was the lowest.The SUA was negatively correlated with HDL C in Kazak (P ＜ 0.05).HDL-C was a recognized protective factor for cardiovascular disease.With the lowered SUA level in the Kazak group,HDL-C level was increased.When SUA level was higher than a certain level (such as the SUA-4),there existed a negative impact on cardiovascular disease

Objective To investigate the management of external iliac artery mycotic hemorrhage after kidney transplantation. Methods A case of external iliac artery mycotic hemorrhage after kidney transplantation managed by the use of hypogastric artery autograft was reported with review of the literature.The massive blooding occurred 3 times after kidney transplantation in a male patient 25 years of age on the 22nd,24th and 38th day after transplantation.The blooding amounted to 800 ml,2500 ml and 3800 ml respectively.The blood loss was replaced and prompt surgical exploration was carried out with the blooding site at the anastomosis sutured up on the 1st and 2nd episode of bleeding.On the 3rd occurrence of bleeding, the diseased external iliac artery segment, about 2cm in length, was resected and the gap was replaced by a 3cm long hypogastric artery autograft. Results The blood flow through the repaired external iliac artery and the blood supply to the lower extremity was adequate.Periodic hemodialysis had been restored and the patient waited for reimplantation. Conclusions External iliac artery mycotic hemorrhage after kidney transplantation is a serious and fatal complication.Simple arterial repair is usually noneffective.Resection of the diseased mycotic segment of the external iliac artery with repairing of the gap with a hypogastric artery autograft is rational,feasible and simple.The procedure is highly recommended.

Animal models with kidney disease are generally divided into two types. One belongs to the models which imitate human kidney disease by the artificial operations, such as anti-glomerular basement membrane antibody nephritis, Heymann nephritis, anti-Thyl. 1 antibody nephritis, BSA nephritis and puromycin nephropathy. The other one pertains to the models which make themselves kidney disease, and appear the pathological characteristics naturally as like as human, such as HIGA mice with IgA nephropathy and NZB/WF1 and MRL/1pr mice with lupus nephritis. In addition,the transgenic animal models with kidney disease can also be established by the modern molecular biologic techniques including gene knockout and siRNA transfection. As for the studies related with kidney disease in pharmacodynamics and pharmacology of Chinese herbal medicine (CHM), it is important to understand deeply the features of each animal model with kidney disease, and select accurately the proper models according to the different experimental objectives, and then, build the special models provided with the combination of disease with syndrome in traditional Chinese medicine (TCM). Therefore,it is the developmental direction for the further study to establish animal models with kidney disease, which should possess the characteristics of syndrome in TCM.

Objective To summarize the treatment experience of refractory systemic juvenile idiopathic arthritis (JIA) by tocilizumab, and to explore the cost-effective treatment. Methods The clinical data of 6 pediatric patients with refractory systemic JIA treated by tocilizumab from 2014 to June 2016 were retrospectively analyzed in the aspects of course and effectiveness of tocilizumab, steroid reduction, adverse reaction, and growth. Results The median age of the six patients (3 males and 3 females) was 6 years, and the course of disease were from 16 to 63 months. All patients were treated by other immunosuppressive agents or biological agents in addition to steroid and traditional anti-rheumatic drug therapy. The courses of tocilizumab treatment were from 7 to 26 months and the median time was 9.5 months. All 6 patients responded to tocilizumab and achieved the clinical remission at different time. After the induced remission, the interval of the treatment intervention was increased from 2 weeks up to 4 weeks in 3 cases, and no disease activity was observed. Except one case, another 5 cases reduced and stopped the use of hormones at 5.8 months after tocilizumab treatment. After hormones was reduced and discontinued, the growth was improved. All 6 patients had no serious adverse reactions. Conclusions Tocilizumab is safe and effective for patients with refractory JIAs. The steroid can be reduced in short time to improve growth. After remission is induced, the interval of the treatment intervention could be prolonged.

The typical manifestations of rheumatoid arthritis are joint pain, swollen and morning stiffness.If the disease is not treated promptly and reasonably,most patients will face joint deformity and physical disability. At present, the choice of evaluation tools related to physical disability is still lack of basis, the influencing factors have not reached the academic consensus, the related interventions are insufficient, rheumatoid arthritis patientsˊ rehabilitation and quality of life can be affected. This article reviews the above three aspects in order to provide the theoretical basis for the development of similar studies and interventions in China.

The method of homogeneity evaluation for active pharmaceutical ingredient (API) spatial distribution in lyophilized product was investigated for the first time with confocal micro-Raman spectroscopy mapping, using pemetrexed disodium for injection as a model drug. Certain areas of the lyophilized product were scanned to obtain Raman spectra. The classical method ("peak clipping" method) was employed for mapping with characteristic Raman peaks of the API and the excipient. Due to the API being finely dispersed in the excipient in lyophilized products, the classical method cannot discriminate between the two ingredients making the distribution homogeneity difficult to evaluate. The "ratio of characteristic peak intensities" method was then utilized. Using this method, the relative intensity of the characteristic Raman peaks of the API to the excipient was applied for mapping and the relative content of API to excipient was calculated for a homogeneity evaluation of the drug distribution. The validation of this method showed a good linear relationship between the relative intensity and the relative content of API to excipient (r² > 0.99), and the precision and recovery were adequate for homogeneity evaluation of API by Raman spectroscopy mapping. Five products of pemetrexed disodium for injection from different manufacturers were tested through Raman maps applying this method and the histograms of relative Raman intensity were also plotted by frequency to help the homogeneity evaluation of drug distribution. The results showed that there were obvious differences in the drug distribution homogeneity from different products, where a more homogeneous API distribution was found in the brand product. This research provides a reliable method for the homogeneity evaluation of API distribution, which facilitates quality evaluation and process optimization of lyophilized products.
