Objective To investigate the relationship among the proliferation of CD4+T cells, the intracellular levels of interleukin-10 (IL-10) and transforming growth factor-?1(TGF-?1), and allergic bronchial asthma. Methods Dermatophagoides farinae antigen were prepared as allergen. Twenty-five patients with asthma and 15 healthy individuals were enrolled and divided into blank control group, allergen group and self control group, respectively, after venous blood sample collection. The proliferation of CD4+T cells and the distributions of CD4+/IL-10+, CD4+/TGF-?+1 and CD4+/IL-10+/TGF-?+1 were measuredby flow cytometry (FCM). Results The distributions of CD4+/IL-10+, CD4+/TGF-?+1 and CD4+/IL-10+/TGF-?+1 could hardly be detected in the peripheral blood samples of the blank controls of the patients with asthma and healthy ones. In the allergen group of the healthy individuals, the peripheral blood CD4+T cells were significantly proliferated, and the proportions of CD4+T cells andCD4+/IL-10+ cells were much higher than the self control group, while there was no significantly increase in the proportions of CD4+/TGF-?+1 and CD4+/IL-10+/TGF-?+1 subgroups. In the allergen group of those with asthma, the proportions of peripheral blood CD4+, CD4+/IL-10+, CD4+/TGF-?+1 and CD4+/IL-10+/TGF-?+1 cells were not found significantly increased compared with those self controls. After being activated by allergen, the proportion of peripheral blood CD4+/IL-10+ cells was significantly lower in the patients with asthma than the healthy individuals(P

ObjectiveTo investigate the risk factors for contrast-induced nephropathy (CIN) after endovascular therapy in patients with peripheral arterial diseases and to evaluate the conformance of serum cystatin C (Cys C) and serum creatinine in diagnosis of CIN. Methods In this prospective,single center study,in-hospital patients with peripheral arterial diseases undergoing non-emergency endovascular therapy from July 2010 to April 2011 in our hospital were enrolled.CIN was defined asScr increase ≥25％ after angiography.General clinical characteristics and blood biochemical parameters were compared between the non-CIN and CIN groups.Logistic regression analysis was performed to determine risk factors.Changes compared to baseline level in serum creatinine and Cys C at predefined time-points were evaluated.Results A total of 367 patients were enrolled in the study.The proportions of patients with diabetes mellims and treatment with diuretics before angiography,contrast-media dosage were significantly higher in the CIN group than those in non-CIN group (P＜0.05,＜0.01,＜0.01).Logistic regression analysis indicated that diabetes mellitus,contrast-media dosage were risk factors for CIN.Several serum Cys C increase criteria at 24 hours after contrast media exposure all had low sensitivity for predicting a Scr increase ≥25％.Only small overlapped regions were found in Venn diagram between several increasing criteria according to serum Cys C and serum creatinine criterion. Conclusions Diabetes mellitus,contrast-media dosage are independent risk factors for CIN.The results of several increasing criteria according to serum Cys C in evaluating contrast-induced AKI are not coincident well with that of serum creatinine criterion.

Objective To investigate the correlation of M-type phospholipase A2 receptor (PLA2R) genetic polymorphism in two single nucleotide polymorphisms (SNPs) with idiopathic membranous nephropathy (IMN) of Chinese Han population in Northeast China.Methods A total of 327 individuals were enrolled in the study including 95 adult patients with biopsy-proved IMN (IMN group) followed up for (25.4±11.6) months and 232 healthy people identified by healthy examination in China-Japan Union Hospital of Jilin University (HC group).Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) was used to detect the genotype and allele frequency of rs35771982 and rs3828323 site in PLA2R gene.The x2 test was performed to compare the distribution difference of allelic frequency and genotype frequency of the two sites in PLA2R gene between two groups.Unconditional Logistic regression analysis was used to determine the risk factor of IMN.Results IMN and HC group were matched in male predominance and body mass index (BMI).Patients with IMN were older than the healthy controls and had higher Scr,serum total cholesterol (TC),24-hour urine protein level and lower serum albumin (Alb) level,lower estimated glomerular filtration rate (eGFR) than the healthy controls (all P ＜ 0.01).The CC genotype frequency and the C allele frequency at SNP rs35771982 site of PLA2R gene in IMN group were significantly higher than those in HC group (x2=13.658,P=0.001;x2=15.315,P=9.10× 10-5),whereas there was no distribution difference of genotype and allele frequency at rs3828323 site between two groups (x2=2.844,P =0.241; x2 =2.959,P=0.085).The CC genotype at rs35771982 site in patients with IMN was not related to,age,gender,BMI,blood pressure and several laboratory indexes such as Alb,TC,Scr,eGFR and 24-hour urine protein level (all P ＞ 0.05).Unconditional Logistic regression analysis revealed that the genotype at rs35771982,age,TC,Scr and eGFR were correlated with IMN occurrence.The CC genotype at rs35771982 was the risk factor of IMN (OR =4.408,95％CI 1.488-13.058).Conclusions The CC genotype and C allele at rs35771982 site in PLA2R may be associated with the susceptibility to IMN,whereas the correlation between gene polymorphism at rs3828323 site and IMN is not demonstrated.The CC genotype at rs35771982 is the independent risk factor of IMN in Chinese Han population in Northeast China.

In recent years (2007 to 2011),although the overall number of rabies cases in China has decreased,there is evidence of emerging or re-emerging cases in regions without previous rabies cases or with low incidence of rabies.To investigate the origin and the factors affecting the spread of rabies in China,specimens were collected from 2007 to 2011 from provinces with emerging and re-emerging cases and tested for the presence of the rabies virus.Positive specimens were combined with sequences from GenBank to perform comparisons of homology and functional sites,and to carry out phylogenetic analyses.Out of these regions,five provinces had 9positive specimens from canine and cattle,and 34 canine or human specimens were obtained from previously high-incidence provinces.Complete sequences of G gene were obtained for these samples.Homology of the sequences of these 43 specimens was 87％-100％ at the nucleotide level and 93.7％ -100％ at the amino acid level.These G gene sequences were combined with reference sequence from GenBank and used to construct a phylogenetic tree.The results showed that 43 specimens were all assigned to China clade I and clade Ⅱ,with all specimens from emerging and re-emerging areas placed within clade I.Specimens isolated from Shanxi and Inner Mongolia in 2011 were distinct from previously-isolated local strains and had closer homology to strains from Hebei,Beijing and Tianjin whereas new isolates from Shanghai were tightly clustered with strains isolated in the 1990s.Finally,Shaanxi isolates were clustered with strains from adjacent Sichuan.Our results suggest that the rabies cases in emerging and re-emerging areas in China in the last 5 years are a consequence of the epidemic spreading from of neighboring provinces and regions experiencing a serious epidemic of rabies.

BACKGROUND: Vascular injuries of the extremitiesy are frequently concomitant with vascular defects and are usually repaired by autologous vessel grafting. However, the source of autologous vessels is limited and the preparation of them is traumatic.OBJECTIVE: To retrospectively evaluate the extremity-preserving efficacy of vascular prosthesis grafting in repairing major vascular injuries of the extremities in 29 cases.DESIGN: A retrospective study.SETTING: Department of Orthopedics and Traumatic Surgery, Center for Battle Wound and Trauma of Chinese PLA, Research Institute of Surgery,Daping Hospital, Third Military Medical University of Chinese PLA.PARTICIPANTS: We selected 29 patients with major vascular injuries of the extremities repaired by vascular prosthesis grafting who received the treatment at the Department of Orthopedics and Traumatic Surgery of the Center for Battle Wound and Trauma of the Chinese PLA of the Research Institute of Surgery of, Daping Hospital of the Third Military Medical University of Chinese PLA between January 1989 and December 2000. There were 23 males and 6 females. Injury sites: 9 cases were at subclavian artery, 6 at axillary artery, 2 at brachial artery, 10 at femoral artery, 1 at femoral vein and 1 at popliteal artery. 11 of these 29 cases (37.9%) were complicated with shock, 8 with fractures and dislocations, 5 with peripheral nerve injuries and 3 with infections.METHODS: The vascular prosthesis was anastomosed end to end with the trimmed culprit vessels. As for the 3 cases with infective arterial injuries,the vessels were placed away from the infected region and were bridged together in a non-inf1ammatory region and then muscles or musculo-cutaneous flaps were used to cover the infected regions.The functions of the extremities of the patients were evaluated according to MAS at week 2 and 1 year after the operation.MAIN OUTCOME MEASURES: The vascular patency rate and the extremity-preserving outcomes..RESULTS: All 29 patients entered the stage of result analysis. Extremitypreserving efficacy: All the patients who underwent vascular prosthesis grafting had their extremities preserved. Only 1 patient had the late sequelae of ulcers in the foot sole due to extended extremity ischemia and nerve damage. The rate of 2-week patency rate of the grafted vessels was 100% and the 1-year rate of patency was 96.5%, as revealed by Doppler blood stream scanning. The excellent and good rate of the function of extremity was 89%.CONCLUSION: Vascular prosthesis grafting is the one of the methods for repairing the major vascular injuries so as to preserve the extremities and their functions.

OBJECTIVETo observe the effect of purgation and detoxification therapy on gastrointestinal dysfunction of critically ill patients undergoing abdominal surgery.

METHODSTotally 56 inpatients with severe gastrointestinal dysfunction after abdominal surgery at ICU of Guangdong Provincial Hospital of Traditional Chinese Medicine were assigned to the treatment group and the control group, 28 in each group. All patients received routine Western medical treatment. Patients in the treatment group additionally took Modified Huanglian Jiedu Decoction (MHJD) and received electroacupuncture (EA) for 7 days. The first exhaust time, defecation time, scores for gastrointestinal dysfunction, mechanical ventilation time, ICU hospitalization time, and 28-day fatality rate were observed. Furthermore, serum levels of diamine oxidase (DAO) and D-lactic acid were detected at day 1, 3, and 7 after treatment.

RESULTSThe first exhaust time and the first defecation time in the treatment group were ahead of schedule, when compared with those of the control group (P <0. 05). Scores for gastrointestinal dysfunction, mechanical ventilation time, serum levels of DAO obviously decreased in the treatment group (P <0. 05). There was no statistical difference in serum levels of D-lactic acid, ICU stay time, the incidence of pulmonary infection, and 28-day mortality between the two groups (P >0. 05). Results of Logistic analysis showed that scores for gastrointestinal dysfunction were related with the incidence of pulmonary infection (P <0. 05).

CONCLUSIONMHJD combined EA could promote the recovery of gastrointestinal function in critically ill patients after abdominal surgery via improving intestinal barrier function, which was benefit for shortening mechanical ventilation time.
