Objective To investigate the myocardial damage in rats fed with corn from Keshan disease area added with bean puree. Methods Male Wistar rats were randomly divided into 3 groups according to their body weights, and fed with corn, corn from Keshan disease area added with bean puree, corn from non-endemic area. The GSH-Px activity of vena cardalis blood was examined in 1 and 3 months, rats were sacrificed after being fed for 6 months to examine the heart changes with HE stain. Results The three groups of GSH-Px activity were different in 1 and 3 months respectively(F=23.60,72.46, all P<0.01); GSH-Px activity was (181.58±22.15), (44.76±28.59)U/L in rats fed with corn, was (195.03±17.66), (30.38±3.35)U/L in those fed with corn added with bean puree from Keshan disease area, lower than the group fed with corn of non-endemic area[(340.90±95.42), (125.17±13.64)U/L, all P < 0.01]. But the difference of GSH-Px activity between simple corn group and corn adding bean puree groups of Keshan disease area was not obvious(P>0.05). Myocardial damage incidence of the three groups was 3/9,1/9,2/7. Difference among three groups did not have statistical significance(χ2=1.33, P> 0.05). Conclusions Only corn from Keshan disease area may induce myocardial damage pathology change. Adding bean puree into corn does not increase damage.

OBJECTIVETo assess the feasibility and safety of excising or patching the inferior vena cava (IVC) without replacement in patients with primary retroperitoneal tumors (PRPT) involving the IVC.

METHODSA retrospective analysis was conducted in 116 consecutive patients with PRPT presented to our Hospital between December 2007 and December 2008. IVC involvement was found in 11.2% of the cases, and in 93 cases receiving surgical tumor removal, the complete resection rate was 93.55%. According to the location of IVC involvement by the PRPT, the cases were classified into 3 groups with IVC involvement in the segment from the second hepatic portal vein to the renal vein (segment A), the segment on the bilateral renal vein plane (segment B), and the segment from the caval bifurcation to the renal vein (segment C).

RESULTSThe most common vascular involvement occurred in segment C (61.54%, 8/13), and 2 cases presented with segment A involvement and 2 had segment B involvement. All the 3 segments of IVC were involved in 1 case. Five cases with IVC involvement received IVC patching only, and 4 had resection or ligation of the segment C of the IVC, and resection of the segment A and B of the IVC was performed in 2 and 1 case, respectively. One patient received complete resection of whole IVC involved. All patients recovered smoothly and were discharged.

CONCLUSIONThe infrarenal IVC can be ligated or resected safely without reconstruction. Combined resection of the bilateral renal vein and segment B of the IVC may result in renal insufficiency. IVC involvement and occlusion between the second hepatic portal and renal veins can be ligated safely without affecting the renal function.

The aim of current study was to detect intron 22 inversion of factor VIII gene in severe hemophilia A (HA) patients and screen the carriers of the gene inversion. Fifty-five cases of severe HA were involved and factor VIII gene inversion was detected and identified by long distance-PCR (LD-PCR) and 0.6% agarose gel electrophoresis. The 11 kb and 12 kb bands indicate the factor VIII gene inversion and non-inversion, respectively. Occurring of both 11 kb and 12 kb bands indicates a carrier of the inversion. The results showed that factor VIII gene inversion existed in 22 out of 55 cases, which accounted for about 40% of total detected patients. Five carriers of factor VIII gene inversion were diagnosed from the members in 15 families. In conclusion, LD-PCR assay is a simple, rapid and accurate method for detection of factor VIII gene inversion, and this approach is helpful in screening, carrier testing, and prenatal diagnosis of severe hemophilia A.

Objective To analyze the HIV/AIDS epidemic situation and related behavioral components among young students in the last years and to provide information for integrated control and prevention programs. Methods Data on young students (1 5-24 years) through case reporting system was collected from 2006 to 2009 and continuous sentinel surveillance data regarding 6 national sentinel sites carried out from 2006 to 2009 was also collected. The sentinel sites would include universities, junior college and secondary vocational colleges registered students, using cluster sampling phases method. Self-administered questionnaire survey and blood (HIV antibody testing and syphilis antibody testing) tests were carried out, with the sample size was about 800 cases per site per year. Results The number of case report on HIV/AIDS among the young students of 15-24 years age group had been rising. Similar trend was also observed on the number of reported cases over the years, accounting for the proportions of the total number of reported cases, as 0.39%, 0.50%, 0.83%and 1.02% respectively from 2006 to 2009. Sexual contacts continued to be the major route of transmission, with the increasing proportion of homosexual transmission. In the 6 national sentinel sites of young students which continuous surveillance was conducted during the period from 2006 to 2009, data showed the following facts as: proportion (median) of objects who admmited to have had sex, were: 4.3%, 4.5 % and 6.1%, proportions (median) of commercial sex occurred in the past year were: 0.3%, 0.2% and 0.3%; proportions (median) of MSM occurred in the past year were: 0.7%,0.2% and 0.2%; median of HIV antibody positive rate and syphilis antibody positive rate were 0%;median of awareness rate on HIV/AIDS were: 49.0%, 75.0% and 80.5%; proportion (median) of monitor objects who received intervention services in the past year were: 44.2%, 54.3% and 50.2% respectively. Conclusion In recent years, the HIV / AIDS number through case reporting system on the young students under 15-24 years age group, was increasing, but the HIV prevalence among young students was still relatively low, in general. The main transmission was sexual. Some young students had been engaged in commercial sex and MSM activities. Health education should be strengthened to increase the awareness of young students on AIDS/STD prevention. It is necessary to take more effective intervention measures to decrease new infection and control HIV/AIDS epidemic among young students.

Objective To analyze the HIV/AIDS epidemics situation among migrant population.Methods Data on HIV/AIDS cases among mobile population through case reporting system was collected from 2008 to 2011.Results The number of reported cases on HIV/AIDS among mobile population had been rising,with proportions of the total reported cases increased from 10.2％ in 2008,to 18.2％ in 2011.Sexual contacts continued to be the major route of transmission.With the increasing proportion of homosexual transmission,HIV/AIDS cases among mobile population moved from high HIV-prevalence areas in the western and central parts to low HIV-prevalence areas in the eastern part of the country.Conclusion In recent years,the number of HIV/AIDS cases among mobile population was increasing in the case reporting system.Data showed that some male rural migrants had been engaged in commercial sex activities that called for more effective intervention measures to be taken to reduce the new HIV/AIDS infections in the migrant population.

We investigated epidemiological characteristic of scrub typhus in Yongshan County,Yunnan Province,China. The serum samples were collected from the patients with fever for detecting the antibody against Orientia tsutsugamsushi (Ot) by colloidal gold immunoassay assay.Rat traps were used to capture rodents.The spleen tissues of the captured rodents were detected by nested-polymerase chain reaction for rickettsia groEL segment.The groEL segments were sequenced and analyzed the homology with the other known sequences.Thirty-four scrub typhus cases were found in Yongshan County,Yunnan Prov-ince from May 2015 to October 2015.Among them,21 cases were confirmed by laboratory tests and 13 cases were clinical di-agnosis diseases.Of these patients,32.35% of the cases occurred in June.The 32.35% were in the group of the 40-49 year-old,and 79.41% were farmers,94.12% exhibited eschar or skin ulcer(31.25% were observed in groin of these cases),and rash developed in 50%.In 39 spleen tissue samples of Rattus flavipectus,9 samples showed positive for groEL gene Ot,but gro-EL gene of Typhus group rickettsia and spotted fever group rickettsia were negative.Sequence analysis showed that YSP30 was closely related to some Saitama related strains of Ot,such as HSB1,FAR1 and UAP4,while the other 8 strains were closely related to some Karp related strains of Ot,such as UT213,UT221 and SH205.It was confirmed that the Yongshan County was the natural foci of scrub typhus by the serological and molecular biological detections.There are Karp and Saitama genotype related Ots in the natural foci.

To analyze the clinical application characteristics of Danggui-Chuanxiong(DG-CX) herb pair in Chinese medicines on basis of real-world, and provide reference for explaining the inherent compatibility regularity and the relationship between clinical applications and disease species. From April 1, 2014 to June 30, 2014, a total of 8 792 prescriptions with both "DG"and "CX" in a large third-grade class-A traditional Chinese medicine(TCM) hospital were selected to establish the database for analyzing the ratio, dosage, and corresponding disease species of DG-CX herb pair. The results showed that, "DG-CX" with ratio "1∶1" had the highest frequency in clinical application(42.4%); the dosage was mainly of 15 g for both DG and CX; the disease species were mainly of encephalopathy and pulmonary diseases. "DG-CX" herb pairs with a ratio greater than "1∶1" accounted for 33.3% of all the prescriptions, and the ratio "3∶2" appeared to be most frequent among them; the dosage was mainly of 15 g for DG and and 10 g for CX; the disease species were mainly of encephalopathy diseases. "DG-CX" herb pairs with a ratio less than "1∶1" accounted for 24.3% of all the prescriptions, and the ratio "2∶3" appeared to be most frequent among them; the dosage was mainly of 10 g for DG and 15 g for CX; the disease species were mainly of encephalopathy diseases. Statistical method was applied to study the compatibility and application characteristics of Chinese herb pairs in clinical prescriptions, effectively discover the medication regularity, provide theoretical basis for clinical herbal prescriptions and provide scientific guidance and reliable data for modern research of Chinese herb pairs.

OBJECTIVETo evaluate the clinical efficacy and safety of treatment of chronic primary glomerulopathy (CPG) patients of Shen deficiency and dampness heat syndrome (SDDHS) by Yishen Qingli Granule (YQG) combined with low-dose Tripterygium Wilfordii multiglycoside Tablet (TWT).

METHODSTotally 231 CPG patients of SDDHS were enrolled in this study (including 60 patients from First Affiliated Hospital of Nanjing University of Chinese Medicine, 58 from First Affiliated Hospital of Nanjing Medical University, 46 from Xinqiao Hospital of Third Military Medical University, 35 from First Affiliated Hospital of Guangzhou University of Chinese Medicine, 14 from First Affiliated Hospital of Soochow University, and 18 from Wuxi Affiliated Hospital of Nanjing University of Chinese Medicine). They were randomly assigned to the control group (116 cases) and the trial group (115 cases) according to block group method. There were 217 cases in the safety analysis set (109 cases in the trial group vs 108 cases in the control group), and 203 cases in the full analysis set (99 cases in the trial group vs 104 cases in the control group). All patients received basic treatment such as ACEI/ARB. Furthermore, YQG (consisting of raw astragalus 10 g, prepared Polygonum Multiflorum 10 g, Pyrrosia 10 g, 1.5 g each package, containing 10 g of crude drugs) was additionally given to patients in the trial group, each package, twice daily. The TWT (10 mg) was given, twice a day. The TWT dose was adjusted according to 24 h urinary total protein (UTP). The placebos of YQG and TWT were administered to those in the control group. The treatment course consisted of 24 weeks and the follow-up visit lasted for 24 weeks. The biochemical indices were observed before and after treatment including 24 h UTP, urine red cell count (U(RBC)), renal functions (BUN, SCr), blood routine test (WBC), and liver functions (SGPT, SGOT). Reverse reactions such as gastrointestinal discomfort, skin rash, and irregular menstruation were also observed.

RESULTSCompared with the control group, the total effective rate was better in the trial group (82.83% vs 61.54%, P < 0.01). Results of stratified comparison of UTP showed better efficacy in the trial group (0.8-3.0 g/24 h, P < 0.01). The UTP decline occurred in the trial group after 8 weeks of treatment, with stable action, showing statistical difference when compared with the control group (P < 0.01). In the trial group, U(RBC) level decreased after treatment but changed more significantly. But there was no statistical difference in the changes when compared with the control group (P > 0.05). After treatment, there were no statistical difference in safety indicators such as WBC, SGPT, and SGOT between the two groups after treatment (P > 0.05).

CONCLUSIONOn the basis of basic treatment such as ACEI/ARB, application of YQG combined with low-dose TWT had better effect in controlling proteinuria of CPG patients, and could help stabilizing their conditions with less adverse reactions.
