ABSTRACT
Objective To report the diagnosis and treatment of an imported case of schistosomiasis haematobium,including the pathological features of the disease and therapeutic efficacy of praziquantel. Methods The data of the patient with schistoso?miasis haematobium were collected,and the pathological features of the bladder tissue were observed under a microscope. More?over,the patient was treated with praziquantel,and his urine was collected before and after the treatment. The eggs in the urine were examined by a microscope after sediment and the miracidia were hatched. Results The patient once worked in Angola for three months,and after returning home he had the symptoms of intermittent painless terminal hematuresis. It was ineffective af?ter anti?inflammatory treatment in a number of hospitals. There were no sand spots discovered under the cystoscope. However , the inflammatory reaction to parasite with a lot of eosinophils infiltration in the bladder mucosa was found on the pathological sec?tions under a microscope,and the egg structure was observed with individual characteristics. The eggs were detected in the urine and the miracidia were hatched before the praziquantel treatment. The hematuria symptoms disappeared after the praziquantel treatment. The eggs were still detected in the urine 7 days post?treatment,but the miracidium could not be hatched. One month and 6 months post?treatment,the eggs were not detected in the urine. Conclusions The imported cases of schistosomiasis hae?matobium are often misdiagnosed,and therefore,it is necessary to strength the health education to the workers overseas and also to improve the ability of diagnosis in medical staff. For the case reported in this paper,there are typical structure of Schistosoma haematobium eggs and egg?granulomas on the pathological sections of bladder tissues. Praziquantel has satisfactory treatment re?sults.
ABSTRACT
Objective:Imatinib is extensively used as a first-line therapeutic agent for patients with chronic myeloid leukemia (CML) at the chronic phase (CP). Although CML patients undergoing imatinib treatment are enrolled mainly in the Glivec International Patient Assistance Program (GIPAP) in China since 2003, limited data have been reported on the long-term outcome of these patients. This study aims to compare the treatment response and prognosis of CML-CP patients who received different treatments from January 2003 to December 2013 in the First Affiliated Hospital of Nanchang University. Methods:A total of 295 patients were enrolled, includ-ing 185, 30, 50, and 30 patients for imatinib, interferon-alpha (IFN-α) plus Ara-C, hydroxycarbamide (HU), or allogeneic hematopoietic stem cell transplantation (Allo-HSCT) treatments, respectively. Results:Patients in imatinib and Allo-HSCT groups achieved excellent complete hematologic remission (CHR) (i.e., 96.7%vs. 96.7%), complete cytogenetic response (CCyR) (i.e., 89.7%vs. 93.3%), and com-plete molecular remission (CMoR) (i.e., 49.7%vs. 83.3%, P=0.001). However, significantly low rates of CHR, CCyR, McyR, and CMoR were observed in IFN-αand HU groups. Moreover, patients from imatinib group showed longer overall survival (OS) time than patients from other groups (P<0.001), even patients in Allo-HSCT group (10-year OS, 89.0%vs. 67.0%, P<0.001) because of high risk of Allo-HSCT-related complication. Multivariate analysis showed that receiving imatinib treatment (HR=5.267, 95%CI:1.054-1.940, P=0.022) and achieving CCyR (HR=9.541, 95%CI:1.692-10.513, P=0.002) were independent predictors for OS. Conclusion:Imatinib treatment may be an optimal first-line choice for Chinese patients with CML-CP who have not received any previous treatments.
ABSTRACT
Objective:This study aimed to achieve the early diagnosis and active treatment of adult hemophagocytic syndrome (HPS) and investigate the clinical characteristics and prognostic factors of this syndrome. Methods:A single-center retrospective analysis was performed to analyze clinical characteristics, laboratory findings, and survival data. Results:In 58 patients, the most common clinical manifestations were fever (100%) and splenomegaly (89.7%). The most common laboratory parameters were serum ferritin 500 g/L (100%) and peripheral cytopenia in two or more lineages (96.6%). platelet count, fibrinogen, and lactate dehydrogenase in the death group were significantly lower than in the survival group (P=0.000, 0.001, and 0.000). Survival analysis results showed that infections in the rheu-matological group exhibited good prognosis [the overall survival (OS) time was not reached in 190 d]. Patients with unexplained causes had moderate prognosis (OS time was 60 d);tumor-associated HPS patients had poor prognosis (the OS time was only 30 d). Univariate analysis results showed that patients with Fbg<1.5 g/L, PLT<40×109/L, and LDH≥2000 U/L also exhibited poor prognosis (P=0.000). Multivariate analysis results showed that PLT<40 × 109/L was an independent adverse factor (HR=6.472, 95%CI:1.526-26.065, P=0.011). Conclusion:HPS exhibits complex clinical manifestations and varied etiology. Patients with infection and rheumatism-related HPS had good prognosiss compared with those manifesting tumor-associated HPS. Fbg<1.5 g/L, PLT<40×109/L, and LDH≥2 000 U/L were the univariate factors that affected the survival time of patients. PLT<40×109/L is an independent adverse factor. These patients need systemic treatments as early as possible.
ABSTRACT
Objective To explore the resistance and molecular mechanisms underlying the anticancer activity of daunorubicin in CD34 +acute myeloid leukemia(AML) cells. Methods CD34 +AML cell lines(KG1a and Kasu-mi-1)were used as objectives, and CD34 -AML cell line U937 was used as positive control. Western blot analysis was used to examine the protein expression of Bcl-2 and Bax in CD34 +AML and CD34 -AML cell lines incubated with/without daunorubicin to compare the sensitivity of CD34 +AML and CD34 -AML cells to daunorubicin. SiRNA against Bcl-2 was used in KG1a and Kasumi-1 cells and examined the effect on cell viability by MTT assay. Results Western blot analysis showed that Bcl-2 protein levels in CD34 +AML cells appeared to be significantly higher than in CD34 -AML cells. Western blot analysis showed that treatment with 0.4 μg/ml daunorubicin for 48 h caused down-regulation of Bcl-2 only in CD34 -AML cells,but not in CD34 +AML cells. Suppression of Bcl-2 with siRNA increased the susceptibility of KG1a and Kasumi-1 to daunorubicin. Conclusion CD34 +AML cell lines ex-press higher levels of Bcl-2 protein. Daunorubicin fails to down-regulate the high Bcl-2 protein levels in CD34 +AML cells. Suppression of Bcl-2 with siRNA increases the susceptibility of KG1a and Kasumi-1 to daunorubicin. The high Bcl-2 protein levels in CD34 +AML cells may be involved in the insensitivity to daunorubicin.
ABSTRACT
The purpose of this study was to investigate the natural infection of Angiostrongylus cantonensis (A. cantonensis) in rodents in Fujian Province and provide more scientific evidences for control and prevention.?Rats captured with cages were numbered, and the species, gender and maturity were identified in each village every day. Rats' hearts and lungs were taken out and soaked into physiological saline solution to tear to pieces. The detected A. cantonensis were put into physiological saline solution in other glassware then the number and gender were identified. This investigation was conducted in 67 villages in 35 towns, covering 23 counties in 9 cities and regions. Except Shanghang County in Longyan city and Pingtan County in Fuzhou city, rodents infected with A. cantonensis was found in 21 counties. Of 4 890 rats were examined and 434 infected rats were identified with an infection rate of 8.90%. Rattus norvegicus had the highest infection rate of 17.75% (315/1 775), following by Rattus flavipectus with an infection rate of 6.21% (49/789). Additionally, the infection rates of the Musk shrew and Mus musculus were 2.81% (29/1 032) and 2.52%(3/119), respectively (χ2＝185.06, P＜0.001). Moreover, the infection rate of adult rats (21.37%) was much higher than that of immature rats (11.11%) (χ2＝14.50, P＜0.05). These results indicated that the A. cantonensis infection of rodents has covered most area in Fujian Province and the geographical distribution of infected rats was similar with that of Ampullaria gigas.
ABSTRACT
In order to understand the situation of schistosomiasis in Fujian Province, the surveillance and field survey data of 16 counties (cities or districts) were statistically analyzed from 2003 to 2008 according to the national and provincial surveillance protocols. The snail areas were 69 400 m~2 in 2003, and 506 700 m~2 in 2004, then decreased to 57 700 m~2 in 2008 after the snail control in 2005 and 2006. Serological examinations were conducted in 18 000 people, among which 5 412 people were the mobile population from schistosome-endemic areas, and 110 persons were positive, among which 8 persons had eggs and miracidia in their stools, among 7 885 appendix samples, Schistosoma japonicum eggs were found in 8 samples of the patients who came from the o-riginal endemic areas. By the stool examination, 2 709 head of farm cattle in the region with snails were not found infected with Schistosoma japonicum. It is suggested that the areas of residual snails are large and widespread, and the imported patients are found frequently, so the danger of schistosomisis transmission still remains.
ABSTRACT
Objective To provide the basis for the differentiation with similar species of intestinal flukes through observing the figure of Haplorchis pumilio. Methods Adults of H. pumilio were collected from the intestine of the cat which was infected with the encysted cercariae of H.pumilio for 45 days. The worms were observed after staining. Eggs and metacercariae of H.pumilio were collected and examined for their shape, size and morphological characteristics. Pseudorasbora parva, the fish host, was examined for the parasitized sites of metacercariae. Results The principal characteristics of the adults is the acetabulum degradation. There are only the genital sucker with 44-48 hamuli. The average measurement of eggs is 31.2?16.7 ?m with a smooth shell. Its aceromion is not evident. The average diameter of metacercariae is 168.5 ?m. There are squamous spines on metacercaria. The metacercariae only parasitize in the muscle between the basis of the fin and the fish body. The average measurement of metacercaria cyst is 445?95?m, with squamous spines on the body surface. Hamuli are found on the genital sucker of metacercaria cyst. Conclusion The morphological figures and parasitic sites of metacercaria, the genital sucker of the adult, and the number and form of the hamulus on the genital sucker provide basis for distinguishing H. pumilio from other intestinal flukes.
