OBJECTIVE: To prepare levamisole ferulate (LF) and investigate its effects on the immune function of mice with low immunity, thus to provide basic evidence for regulation of the immune status of animals and improvement of body's defense. METHODS: LF was synthesized by levamisole hydrochloride and sodium ferulate. The model of immune inhibited mice was established by intraperitoneal injection with cyclophosphamide (CTX). In order to verify and compare the effect of immune enhancement, a series of parameters were determined such as the immune organ index, the serum IgA, IgG and IgM in cyclophosphamide-induced-immunosu-pressed mice. RESULTS: The product was obtained and its yield was 80.49%. The identification of the product was done by means of elemental analysis, TLC, UV-Vis, IR and ESI-MS. LF significantly increased the contents of IgM and IgG in cyclophosphamide-in-duced-immunosupressed mice and improved the thymus and spleen indexes. CONCLUSION: This synthetic technique is simple and feasible. LF can significantly regulate the immune function in mice. Copyright 2012 by the Chinese Pharmaceutical Association.

The effect of traditional therapy is limited for liver cancer,gene therapy gets more and more recognition in recent years.Oncolysis virus is a kind of conditionally replicating virus,with special reproductivity in cancer cells,and then kills them.Gene agents are usually introduced into tumor tissue by intra-tumor and intra-arterial injection,and the technique of interventional therapy is able to satisfy the demand excellently.So,some breakthrough is expected in treating liver cancer by skillfully combining oncolysis virus and interventional technique

Objective To investigate the clinicopathological features of hepatitis B virus-associated glomerulonephritis(HBV-GN) in children.Methods Clinical and pathological features were analyzed and correlated in 73 cases with renal biopsy-confirmed(HBV-GN).Sixty-six boys and 7 girls aged from 1 to 14 years old were included in this study,accounting for 14.4% in children under-(going) renal biopsy in the same period.Results Nephrotic syndrome(NS) was the prodominant clinical manifestation(53/73,72.6%),followed by glomerulonephritis(15/73,20.5%) and hematuria with proteinuria(5/73,6.9%).Serologic markers of HBV were found in all cases.Among them,55 cases(75%) were positive for hepatitis B surface antigen(HBsAg),hepatitis B e antigen(HBeAg) and anti-hepatitis B core(anti-HBc),14 cases(19.2%)positive for HBsAg,anti-HBe and anti-HBc,2 cases positive for HBsAg and anti-HBc,1 child positive for HBsAg and HBeAg,and another only positive for anti-HBc.The most common pathological type of HBV-GN was membranous nephropathy(MN),which was found in 69 cases(94.5%),followed by membranoproliferative glomerulonephritis(MPGN) and mesangial proliferative glomerulonephritis(MsPGN),2 cases(2.7%),respectively.All cases with NS presented themselves with MN.The pathological grades were significantly correlated with clinical manifestations through double trend analysis(?~2=5.22 P=0.022).Conclusions MN is predominant in childhood HBV-GN,which mainly presented with NS.Their clinical patterns are somewhat correlated with pathological grades.

OBJECTIVE To enhance the control of nosocomial infection and improve the quality of medical nursing. METHODS The risk factors and etiological factors of nosocomial infection in sickroom were analyzed. RESULTS In order to control the nosocomial infection we needed to strength the disinfection management in the following aspects: air in the ward,nursing procedures,implements and hands of doctors and nurses. CONCLUSIONS Strict sterilizing procedures and standardized monitoring are the important measures to reduce the nosocomial infection.

Objective To evaluate the effect of pneumatic ureteroscopic lithotripsy(URSL) for ureteral calculi.MethodsA total of 378 cases of ureteral calculi received URSL in our hospital by using F8/9.8 Wolf rigid ureteroscope and EMS Ⅱ pneumatic lithotripter(Switzerland).Among the cases,213 had calculi at the left side,158 at the right side,and 7 at the both sides;81 had the stones in the upper ureter,146 in the middle segment,and 158 in the lower part.Results In the cases,313 patients(320 sides) were cured after the first operation with a success rate of 82.8%(313/378).The success rates for the upper,middle,and lower ureteral calculi were 60.5%(49/81),84.2%(123/146),and 93.7%(148/158),respectively.The stones were removed completed in 1 to 8 weeks after the procedure.Fifteen patients were converted to an open surgery.In 3 patients,the URSL were stopped due to failure in placing the ureteroscope.The main postoperative complications in our series included perforation of the ureter(8 cases) and fever(13).Conclusions USRL is a safe,minimally invasive,and effective treatment.It should be the first choice for middle and lower ureteral calculi.

Objective To explore the clinical features of pulmonary tuberculosis complicated with DM and related factors. Method The manifestations of 87 newly diagnosed PTB patients with type 2 DM(DM-PTB group) at two hospitals in Tianjin during October 2003 to October 2004 were compared to 88 PTB patients without DM who were randomly choosen from the same hosipital.The factors related to sputum-positive TB or cavity were explored through unconditional logistic regression model. Results DM-PTB patients showed significanly lower frequencies of cough(66.7% vs 83.0%),toxicity symptoms(37.9% vs 62.5%) and haemoptysis(16.1% vs 33.0%) than those of PTB group.Positive-sputum(63.2% vs 34.1%),cavity(56.3% vs 13.6%),wide lesions and bilateral lesions on chest radiographs was more common in DM-PTB group than in PTB one.Introversion(OR=1.582, 95%CI:1.063 ～2.355),type 2 DM(OR =2.186,95% CI:1.082 ~4.420)and cavity(OR =2.793,95% CI:1.308 ～5.964)were factors independently associated with positive-sputum TB.The factors related to cavity included diabetes(OR=14.199,95%CI:5.376~ 37.501),cough,postive sputum and lore-up lobe lesion.Conclusion This study confirmed that clinical manifestations and chest radiographs of PTB patients complicated with type 2 DM significantly departed from the typical presentation.Type 2 DM seems to have a negative effect on postive-sputum and cavity.So it should be alarmed that DM-PTB patients who tend to have untypical clinical symptom and higher rate of positive sputum become the reservoirs of infection to cause the transmission of TB.
