Objective To investigate the expression of anionic site in adriamycin-induced nephropathy (AN) rats, and to further explore the effects of Qufengtongluo Recipe on charge barrier in glomerulus in AN rats. Methods Adriamycin nephropathy was induced by a single tail intravenous injection of adriamycin. Totally 80 rats were randomly divided into normal control group and nephropathy model group. Three weeks later, the nephropathy model was established, and 50 AN rats were randomly divided into five groups: nephropathy model group (B, n=10), Qufeng group (C, n=10), prednisone and Qufeng group (D, n=10), prednisone group (E, n=10) and benazepri group (F, n=10), and they were treated respectively. With treatment being given respectively, renal tissue samples in each group were collected at week 3 and 7, respectively. The ultrastructure and expression of anionic site were examined by electron microscope observation. Results ① After adriamycin injection, a significant increase of the 24-hour urinary protein was observed at week 3 (P<0.01). In AN rats, serum albumin was decreased (P<0.01) while serum TCH and TG were increased (P<0.01). ② In AN rats the diffuse fusion and effacement of foot processes and decrease of anionic sites in GBM were observed at week 3. ③ At week 7, the average intensity of AS dramatically increased in C and E groups (P<0.01) compared with that in nephropathy model group. Conclusion The abnormal expression of AS is the important mechanism that leads to the occurrence and development of proteinuria in AN rats. It is possible that Qufengtongluo Recipe has effects on nephrotic syndrome through altering the charge barrier in GBM in glomerulus.

Objective To investigate the expression of nephrin mRNA in adriamycin-induced nephropathy (AN) in rats, and to explore the effect of Qufengtongluo recipe on proteinuria in AN rats and on the expression of nephrin mRNA. Methods Adriamycin nephropathy was induced by a single tail intravenous injection of adriamycin. We randomly divided 140 rats into a normal control group (n=32) and a nephropathy model group (n=108). Three weeks later, 90 AN rats were randomly divided into 5 groups: a model group, a qufeng group, a qufeng and prednisone group, a prednisone group, and a benazepri group (18 rats in each group). They were treated respectively, and renal tissue samples were collected at week 0, 3, 5, and 7, respectively. The distribution and expression of nephrin mRNA were examined by indirect immunofluorescence and semi-quantity RT-PCR. Results In the AN rats, the diffuse fusion and effacement of foot processes were observed at week 3. The fluorescence intensity of nephrin and the expression of nephrin mRNA significantly increased in the qufeng group and the prednisone group compared with the model group at the week 7 (P＜0.01).Conclusion Abnormal expression of nephrin is the important molecular mechanism that leads to the occurrence and development of proteinuria in AN rats. Qufengtongluo recipe has effect on nephrotic syndrome through altering the expression and distribution of nephrin in glomerulus.

Chemometrics processes complicated data of TCM through applied mathematics, statistics and com-puter technology. And multivariable study was introduced into the quantitative characterization of TCM with great achievements. This article reviewed existed problems of quantitative characterization in TCM, the principles, char-acteristics, limitations, commonly used statistical methods and application conditions on quantitative characteriza-tion of TCM. With this review, a reference for further study of quantitative characterization of TCM was provided and a further research idea of combination with main methods of chemometrics was given.

Objective To investigate the associated risk factors of postoperative complications after rad?ical resecting of colorectal cancer. Methods The clinical data of 237 patients with colorectal cancer performed radical resection in the Second Affiliated Hospital of Kunming Medical University from January 2011 to Decem?ber 2014 were analyzed retrospectively. The incidence of postoperative complications was analyzed,and the relat?ed factors were analyzed by single factor and multi factor correlation analysis. Results The postoperative com?plications occurred in 114 cases of 237 patients( 48. 1%) . Univariate analysis showed that the age more than 70 years old,preoperative comorbidity,intraoperative blood loss,surgeon’ s experience,combined evisceration or en?larged evisceration were related to postoperative complications ( P = 0. 033, 0. 014, 0. 045, 0. 028, 0. 040 ) . Compared with the patients without complications,the postoperative anal exhaust time,length of stay was longer of the patients with complications((3. 7±1. 6) d vs. (3. 2±1. 4) d,P=0. 035;(21. 3±6. 5) d vs. (12. 1 ±2. 4) d,P=0. 001). Logistic regression analysis showed that depth of tumor invasion(P=0. 001),preoperative comorbidity including NRS>3 points (χ2 =8. 903, P=0. 003 ) , anemia and hypoproteinemia (χ2 =3. 494, P=0. 048) ,hypertension complicated with type 2 diabetes mellitus(χ2=5. 418,P=0. 026) ,not complete intesti?nal obstruction(χ2=8. 376,P=0. 003),mild and severe ventilation dysfunction(χ2=6. 331,P=0. 011) and WBC<3. 9×109(χ2=4. 256,P=0. 041) were closely related to the occurrence of complications. The rate of post?operative complication of laparoscopic group and open group had no significant difference( 44. 4%( 64/144) vs. 47. 3%(44/93),P>0. 05) . Conclusion Age>70 years old,preoperative comorbidity,intraoperative blood loss,surgeon`s experience,combined evisceration or enlarged evisceration are main risk factors for patients per?formed colorectal cancer radical resection,but laparoscopy?assisted radical resection is not the risk factor.

AIM To investigate the effects of several 5-hydroxytryptamine(5-HT) subtype receptor antagonists on late slow excitatory postsynaptic potential(LS-EPSP) of the neurons of guinea pig inferior mesenteric ganglion(IMG). METHODS Intracellular recordings were made from neurons of the isolated guinea pig IMG. RESULTS Cyproheptadine and BRL 24924 suppressed LS-EPSP of 5-HT sensitive neurons reversibly, while mianserin, MDL 72222 and spiperone showed no significant effect. Continuous superfusion of IMG with MCPP suppressed LS-EPSP of 5-HT sensitive neurons by 5-HT 1P receptor desensitizated. CONCLUSION LS-EPSP of 5-HT sensitive neuron is mediated by 5-HT 1P subtype receptor.

Objective To observe the clinical efficacy of"three modulation acupuncture"combined with repeated functional magnetic stimulation(rFMS)in the treatment of neurogenic bladder with detrusor muscle weakness after spinal cord injury.Methods A total of 120 patients with neurogenic bladder with detrusor muscle weakness after spinal cord injury were divided into conventional treatment group,"three modulation acupuncture"treatment group,rFMS treatment group and comprehensive treatment group according to the random number table method,with 30 patients per group.The conventional treatment group was given conventional rehabilitation treatment,the"three modulation acupuncture"treatment group was treated with"three modulation acupuncture"(modulating spirit,modulating reflex arc,and modulating lower jiao and waterway)based on conventional rehabilitation treatment,the rFMS treatment group was treated with rFMS based on conventional rehabilitation treatment,and the comprehensive treatment group was treated with"three modulation acupuncture"and rFMS based on conventional rehabilitation treatment.The first desire to void(FDV),maximum cystometric capacity(MCC),maximum detrusor pressure of urine storage period(Pdet.max),maximum intravesical pressure of urine storage period(Pves.max),average daily urination frequency,average daily urine leakage,residual urine volume,and neurogenic bladder symptom scores of the patients were compared before and after treatment,and the clinical effectiveness of each group was evaluated.Results After treatment,the FDV,MCC,and Pdet.max of the four groups were all increased compared with those before treatment,and Pves.max,the average daily urination frequency,the average daily frequency of urine leakage,the residual urine volume,and the neurogenic bladder symptom scores were all decreased(P<0.05).After treatment,the FDV,MCC,and Pdet.max of the"three modulation acupuncture"treatment group,the rFMS treatment group and the comprehensive treatment group were all higher than those of the conventional treatment group,and Pves.max,the average daily urination frequency,the average daily frequency of urine leakage,the residual urine volume,and the neurogenic bladder symptom scores were all lower(P<0.05).After treatment,the comprehensive treatment group had a higher FDV,MCC,and Pdet.max than the"three modulation acupuncture"treatment group and rFMS treatment group,and Pves.max,the average daily urination frequency,the average daily frequency of urine leakage,the residual urine volume,and the neurogenic bladder symptom scores were lower(P<0.05).The curative efficiency rates were 86.2%(25/29)in the"three modulation acupuncture"treatment group,85.7%(24/28)in the rFMS treatment group,and 92.6%(25/27)in the comprehensive treatment group,which was higher than that of the conventional treatment group,which was 75.9%(22/29).Conclusion"Three modulation acupuncture"and rFMS can effectively improve the functional status of the bladder in patients of neurogenic bladder with detrusor muscle weakness after spinal cord injury,and their combined application has a synergistic effect.

Mycobacterium (M.) vaccae is a fast-growing species of saprophytic bacteria that is widely distributed. To understand the host immune responses induced by M. vaccae isolated from bovine submaxillary lymph nodes, C57BL/6 mice were infected with reference strain M. vaccae Bacillus Calmette-Guérin (BCG) and isolated M. vaccae using intraperitoneal injections. Comparison of the bacterial replication and organ pathology between M. vaccae and M. vaccae BCG revealed that M. vaccae was more malignant than M. vaccae in mice. We also demonstrated that serum from the M. vaccae-infected mice contained a higher expression level of gamma-interferon (IFN-γ), tumor necrosis factor alpha, monocyte chemoattractant protein-1, interleukin (IL)-4, IL-12, IL-10 and transforming growth factor beta than did the other groups, especially after week 4. Furthermore, when the numbers of CD3⁺CD4⁺IFN-γ⁺ and CD3⁺CD4⁺IL4⁺ cells in the infected mice were observed by flow cytometry, we found that a powerful T helper 1 (Th1) response was induced by M. vaccae infection, which was associated with the emergence of CD3⁺CD4⁺IFN-γ⁺ cells. However, the Th1 response declined over time, which was associated with appearance of the CD4⁺CD25⁺FoxP3⁺ and CD4⁺CD25⁺CD152⁺Treg cell reaction. In addition, a strong Th2 response was found. Finally, we found that M. vaccae infection increased the production of type I IFNs, which was associated with a reduced Th1 response.

Objective: To review the clinical-pathology characteristics of 19 relapsed pediatric mature B cell lymphoma and to find the risk factors for recurrence and the feasible treatment after relapse. Method: Data of 212 pediatric B cell lymphomas cases in Beijing Children′s Hospital from January 2006 to June 2015 were collected retrospectively. All the patients were treated according to the B cell lymphoma regimen of Beijing Children′s Hospital. During the study period, 19 of 212 cases were relapsed; the clinio-pathological characteristics of relapsed patients before treatment and after relapse were analyzed retrospectively, the treatment outcomes after relapse were summarized and the patients were followed-up. Result: Nineteen of 212 cases had relapsed disease, for these relapsed patients: the median age at initial diagnosis was 5.5 years old, the median level of uric acid was 384(range, 121-713)μmol/L, the median level of lactate dehydrogenase(LDH) was 1 323(range, 146-6 370)U/L. Among 19 relapsed patients, 10 had local relapse and 9 had multiple relapses; 17 were Burkitt′s lymphoma and 2 were diffuse large B cell lymphoma. Staging: 2 cases were stageⅡ, 3 cases were stage Ⅲ and 14 cases were stage Ⅳ. Risk group: 6 cases were group B and 13 cases were group C. Nine cases had bone marrow involvement and 10 cases had central nervous system(CNS) involvement. Acute tumor lysis syndrome was seen in 6 cases during the early treatment and 13 cases had delayed treatment. Treatment after relapse: 10 cases received further treatment after relapse (rituximab + 1-4 courses high intensity second-line chemotherapy), 3 cases received autologous stem cell transplantation. There was no chemotherapy or infection related death, 3 cases achieved complete remission (CR). For all the 212 patients, the median follow-up time was 47 (range, 1-131)months and the 5-year event free survival(EFS)rate was (89.4±0.2)%. For the 19 relapse cases, the 5-year overall survival (OS) rate was (21.1±0.1)%, CR rate after relapse was 30%, patients died of the progression of the primary disease, no treatment related death occurred. Univariate analyses showed that bulky disease, stage Ⅳ, maxillofacial and CNS involvement, LDH>1 000 U/L, delay treatment, day 7 evaluation shrink <25%, residual diseases after 3 months treatment are relapse risk factors (all P<0.01). Conclusion Patients relapse during the treatment or at the early stage after the end of all chemotherapy have poor prognosis. So far there is no effective method for early relapse patients; the late relapse patients had the possibility of CR if they are sensitive to salvage treatment. In conclusion, to improve the outcome, the key point is to reduce the relapse.

Objective:To investigate the prognostic significance of high sensitivity-C reactive protein (Hs-CRP) in patients with peripher-al T-cell lymphoma (PTCL). Methods:A total of 234 newly diagnosed PTCL patients with a median age of 48 years were analyzed retro-spectively. Serum Hs-CRP levels and other factors, including tumor stage and international prognostic index (IPI), were determined. Af-ter a median follow-up of 23 months, the relationship between Hs-CRP and overall survival (OS) was observed. Results:Serum Hs-CRP level positively correlated with IPI score (r=0.132, P<0.001), tumor stage (r=0.183, P=0.005), B symptoms (r=0.225, P=0.001), and lactic dehydrogenase (r=0.169, P=0.009), but negatively correlated with plasma albumin levels (r=?0.343, P<0.001), hemoglobin concentra-tion (r=?0.239, P<0.001), and platelet count (r=0.131, P=0.045), and is uncorrelated with age (P>0.05), gender (P>0.05), fitness score (P>0.05), and leukocyte count (P>0.05). Patients with serum Hs-CRP levels≤10 mg/L had better OS than patients with serum Hs-CRP levels>10 mg/L. Univariate and multivariate Cox regression models showed that platelet count, Hs-CRP, albumin levels, and IPI score were independent adverse prognostic factors. Conclusion:The baseline Hs-CRP level can serve as a major indicator of prognosis in PT-CL patients.
