Objective To investigate the characteristics and related risk factors of patients with lymphoma complicated with tuberculosis (TB), the possible pathogenesis and effective therapy. Methods Twenty-one cases of lymphoma combined with TB were retrospectively analyzed by clinical manifestations,pathological features,diagnostic methods,treatments and prognosis.Results Six cases were diagnosed as TB after the diagnosis of lymphoma,5 cases of which were undergoing chemotherapy for lymphoma; 13 cases were diagnosed as lymphoma after TB,including 6 of 10 obsolete pulmonary TB were reactivated during undergoing chemotherapy. Two cases were diagnosed lymphoma and TB simultaneously. Six cases of 21 cases were Hodgkin lymphoma, whereas the other 15 cases were non-Hodgkin lymphoma. Conclusion TB and lymphoma may exist in the same patient in areas where TB is endemic; among this population,the proportion of Hodgkin lymphoma was higher than in the general population.Therefore,the possibility of TB reactivation when undergoing chemotherapy must be focused on.

BACKGROUND:Liver fibrosis is a kind of chronic and active disease that is caused by various causes and characterized by the excessive accumulation of extracelular matrix. At present, use of Chinese herbs for the treatment of hepatic fibrosis has obvious advantages. Salvia miltiorrhiza has been shown to be highly effective in the treatment of hepatic fibrosis. However, the underlying mechanism needs further investigation. OBJECTIVE:To investigate the effects of TanshinoneⅡA on the expression levels of transforming growth factor-β/Smads signaling pathway related factors transforming growth factor-β, bone morphogenetic protein 7, Smad6 and Smad7 in the liver tissue of rats with hepatic fibrosis. METHODS:SD rats were randomly divided into three groups (n = 10): normal control, model and TanshinoneⅡA-treated groups. Rats in the model and TanshinoneⅡA-treated groups were subtaneously injected with olive oil-diluted 10% CCl4 ( 5 mL/kg) twice a week, 8 weeks in total, to build rat models of hepatic fibrosis. Four weeks after hepatic fibgrosis induction, rats in the TanshinoneⅡA-treated group received subtaneous injection of TanshinoneⅡA til eight weeks. Rats in the normal control group were subcutaneously injected with olive oil. RESULTS AND CONCLUSION: Western blotting and reverse transcription-polymerase chain reaction (RT-PCR) detection showed that in the model group, the expression of transforming growth factor-β in the rat liver tissue was significantly increased (P < 0.01) and the expression of bone morphogenetic protein-7, Smad6 and Smad7 was significantly decreased (P < 0.01) compared with the normal control group. TanshinoneⅡA could obviously reverse the expression of those factors above-mentioned (P < 0.01). The results suggest that TanshinoneⅡA can be used for treatment of hepatic fibrosis by decreasing the expression of transforming growth factor-β and increasing the expression of bone morphogenetic protein-7, Smad6 and Smad7.

Continuous exposure to conventional glucose-containing lactate-buffered solutions will ultimately lead to irreversible changes of the structure and function of peritoneum.Therefore,the development of novel peritoneal dialysis(PD) solutions has become the focus in the PD fields in recent years.Icodextrin,which has more adventages than conventional PD solutions,is one of the most important advancements in the past decade.Icodextrin has better biocompatibility,and can reduce the absorption of carbohydrates to decrease the metabolic complications in PD patients.Apart from increasing ultrafiltration,icodextrin can also improve the fluid status and protect the residual renal function of PD patients.However,adverse consequences may result from the pseudo-hyperglycaemia caused by limited measurement of serum glucose.This article reviews the features and applications of the new PD solutions—icodextrin solutions.

Objective To evaluate the status of iodine deficiency disorders(IDD) in Huai'an City in 2011 and to provide a scientific basis for adopting target prevention strategies timely and adjusting the intervention policy scientifically.Methods According to The National Project of Surveillance on IDD,probability sampling method (PPS) was used to select 30 counties in Huai'an City,and one primary school was selected randomly from each county,then 40 children aged 8 to 10 were randomly selected in each school.Children's thyroids were examined by palpation and the iodine in salt samples collected in their home was tested by direct titration.At the same time,urine samples from 12 children of the 40 selected children were collected and urinary iodine was tested by As(Ⅲ)-Ce4+ catalytic spectrophotometry.Questionnaire survey of IDD was conducted among 30 students of grade 5 and 5 housewives around that school.Results A total of 1200 children aged 8 to 10 were examined,and the goiter rate was 1.3％(15/1200).All the goiters were level Ⅰ.The goiters of each age group was 0.8％(3/390),1.8％(7/390) and 1.3％(5/420),respectively.The 360 urine samples were collected from children aged 8-10,and the median of urinary iodine was 171.5 μg/L with the proportions of ＜ 20 μg/L,＜ 50 μg/L and ＜ 100 μg/L were 0(0/360),1.1％ (4/360) and 5.6％ (20/360),respectively.A total of 1200 salt samples were tested in children's family.The coverage rate of iodized salt was 99.4％ (1193/1200) and the qualified rate of iodized salt was 97.7％ (1165/1193).The consuming rate of qualified iodized salt was 97.1％(1165/1200),and non iodized salt rate was 0.6％(7/1200).The knowledge rates of IDD were 82.7％ (2234/2700) and 69.8％ (314/450) in 900 students and 150 housewives,respectively.Conclusions In Huai'an City,except the knowledge rate of IDD,the goiter rate and urinary iodine of children aged 8-10,iodized salt consumption maintain at the stage of the target level.In addition to strengthen the monitoring of iodized salt and to supply qualified iodized salt,it should also increase the focus on health education propaganda in the future.

Objective To investigate the changes in intrapulmonary shunting during controlled hypotension induced by sodium nitroprusside(SNP)in patients undergoing naso-endoscopic operation.Methods Forty ASAⅠorⅡpatients of both sexes(23 male,17 female)aged 16-50 yrs weighing 50-75 kg undergoing naso-endoscopic operation under general anesthesia with muscle relaxation and mechanical ventilation were studied.Radial artery was cannulated for direct BP monitoring and blood sampling.Right internal jugular vein was cannulated and the catheter was advanced into right ventricle.Blood sample taken from right ventricle was used as mixed venous blood instead of blood from pulmonary artery.ECG,MAP,HR and P_(ET) CO_2 were continuously monitored during operation Cardiac output was monitored with noninvasive cardiac function monitor(NC-COM.)based on impedance principle.SNP infusion was started at the beginning of operation at 1-3?g?kg~(-1)?min~(-1) and was then adjusted.MAP was reduced by 30%-40% and maintained at this level until the end of operation.Blood samples were taken from artery and right ventricle simultaneously before SNP infusion(T_1,baseline)at 30 and 60 min of hypotension(T_2,T_3)and at 20 min after BP returned to the baseline level(T_4)for blood gas analysis.Qs/Qt was calculated.Results Qs/Qt was significantly increased during controlled hypotension at T_2 and T_3 as compared to the baseline value(P＜0.01)and returned to the baseline level at T_4.HR was increased and cardiac output and stroke volume was significantly reduced during hypotension as compared to the baseline value.Conclusion The intrapulmonary shunting is increased and the hemodynamics is depressed during SNP-induced controlled hypotension and they return rapidly to baseline level after SNP is discontinued.No hypoxemia develops during SNP- induced hypotension.

Integration and sharing of biological samples are the most effective approach for making use of their stock and improving their utilization efficiency. Although great success has been achieved in development of Biolog-ical Samples Library in China, efforts are not made in promoting sample resource sharing. The problems in develop-ment of Biological Samples Library were thus summarized in this paper by content analysis, such as no unified crite-ria, poor administrative management, and imperfect ethical supervision of sample sharing.
