Advanced schistosomiasis,encompassing a wide range of pathologic entities and multi-complications,poses a se-rious threat on the patients'health. Through comprehensive analysis and evaluation on related aspects regarding clinical classifi-cation,main methods of auxiliary examination and treatment(including types of surgical procedure)of advanced schistosomia-sis,we think that the individual based multidisciplinary comprehensive treatment according to varying conditions of patients is the most optimal treatment mode of advanced schistosomiasis. It is further proposed that multidisciplinary collaborative diagnosis and treatment system should be undoubtedly established,multidisciplinary case discussions be regularly organized,and treat-ment expert teams be stably formed,in order to significantly improve the level of diagnosis and treatment of advanced schistoso-miasis,so as to reduce the misdiagnosis and improve the therapeutic effect in advanced schistosomiasis control.

Objective To evaluate the therapeutic effect of spironolactone on schistosomal pulmonary arterial hypertension(SPAH). Methods A total of 62 patients suffered from hepatosplenic schistosomiasis with pulmonary arterial hypertension were divided into the spironolactone group(n=31) and control group (n=31). All the patients underwent serial echocardiography and the clinical effect before and after the treatment was evaluated by assessing the mean pulmonary arterial pressure (mPAP) and pulmonary arterial diameter (PAD). At the same time, the varieties of the clinical symptoms, signs and the distance of the 6-minute walking test (6-MWT) were investigated. Results In spironolactone group, mPAP(-x±s) decreased from (31.8±7.1) mmHg to (21.2±2.1) mmHg, PAD(-x±s) decreased from (28.0±5.0) mm to (20.0±3.5) mm before and after the treatment respectively(P<0.01). There were significant differences in mPAP, PAD, the distance of 6-MWT and the heart function before and after the treatment in the spironolactone group. However, the data did not show the significant difference in the control group. Conclusion The therapeutic effect of spironolactone in the treatment of SPAH is satisfactory.

Objective To explore the classification of ultrasound images of hepatic parenchyma of schistosomiasis japonica. Methods A total of 2 918 hepatic photographs were selected and classified . All the photographs came from the former research project, which had B ultrasonography examination for residents from three medium endemic villages adjacent to the Dongting Lake,such as Huarong, Hanshou, Lixian, and for advanced schistosomiasis patients in Xiangyue hospital. Results For these hepatic parenchyma images there were five types, including normal echogenic dots (91 photographs), widened echogenic dots (1 757 photographs), echogenic paths(121 photographs), e-chogenic strips (467 photographs) and echogenic bands (482 photographs), etc. , and eight patterns, including nomal echogenic dots (91 photographs), widened echogenic dots (1 757 photographs), echogenic slices (59 photographs), echogenic patches (62 photographs), fine strips (323 photographs), coarse strips (144 photographs), narrow reticular(280 photographs) and wide reticular (202 photographs). Conclusion B ultrasonic images of the liver of schistosomiasis japonica can be classified into five types and eight patterns.

Objective To understand the direct medical expense for surgical patients with splenomegalic advanced schisto?somiasis and its influencing factors,so as to provide evidences for relevant departments to improve the rescue strategy of ad?vanced schistosomiasis. Methods The data about the expenses of patients with splenomegalic advanced schistosomiasis hospi?talized in Xiangyue Hospital affiliated to Hunan Institute of Schistosomiasis Control from January 2010 to August 2014 were col?lected,the hospitalization expense and hospital stays of the patients were analyzed,and the factors influencing the hospital ex?penses were analyzed by the univariate and multi?factor analyses. Results From January 2010 to August 2014,totally 249 cas?es were hospitalized in the hospital,their average hospital stays and hospital expenses were 28.92 d and 18 896.13 Yuan,and both of them were increased year by year. Among all the kinds of expenses,the constitution ratios of the medicine expenses were the highest,and those in the 5 years were all above 44%. The results of the univariate and multi?factor analyses showed that the hospital stays,the amount of intraoperative bleeding,liver function classification,postoperative complications,age,portal hy?pertensive gastropathy were the influencing factors of the hospital expenses. Conclusion Presently,the burden of the direct hospital expenses of the patients with splenomegalic advanced schistosomiasis is still heavy. The government should further im?prove the proportion of the compensation of medical assistance and perfect the medical aid scheme. Meanwhile ,the hospitals should strengthen the management and standardize medical behavior to reduce the hospitalization expenses of the patients.

Advanced schistosomiasis is the most serious clinical type of schistosomiasis. Its diagnosis and treatment are relat?ed to many special departments,such as gastroenterology,general surgery,neurology,endocrinology,radiology,traditional Chinese medicine,blood purification,endoscopy,intervention,and ICU. It is necessary to apply a multidisciplinary treatment (MDT)mode. However,the mode has no universal standard and guide in practice. It is very important for the implementation of MDT mode of advanced schistosomiasis to form a treatment expert team,formulate the formal working procedures,and standard?ize the treatment schedules. The standardized implementation of MDT mode will be important to provide a more effective clinical decision on advanced schistosomiasis.

The medical assistance to advanced schistosomiasis patients established by the Chinese government is a major public facility for patients with advanced schistosomiasis. Since the medical assistance to advance schistosomiasis patients in Hu?nan Province started ten years ago,a set of mature and operable programs with whole program management and related technolo?gies has been developed. The author investigated the data on medical assistance to advanced schistosomiasis patients in Hunan Province during the last 10 years(from 2006 to 2015)retrospectively,and found that the program had high therapeutic effect and high satisfaction degree of both patients and the society. In order to improve the management of the medical assistance to ad?vanced schistosomiasis patients and share our experiences of the whole program management and related technologies with the colleagues of other provinces,this paper mainly illustrates the experiences of the program,as well as the existing problems and related strategies.

This study examined the synergetic effect of class IA Phosphoinositide 3-kinases catalytic subunit p110β knockdown in conjunction with oxaliplatin treatment on colon cancer cells. Down-regulation of p110β by siRNA interference and oxaliplatin treatment were applied in colon cancer cell lines HT29, SW620 and HCT116. MTT assay was used to measure the inhibitory effect of p110β knockdown on the proliferation of colon cancer cell lines. SubG1 assay and Annexin-V FITC/PI double-labeling cytometry were applied to detect cell apoptosis. And cell cycle was evaluated by using PI staining and flow cytometry. The expression of caspase 3, cleaved PARP, p-Akt, T-Akt and p110β was determined by western blotting. The results suggested that down-regulation of p110β expression by siRNA obviously reduced cell number via accumulation in G(0)-G(1) phase of the cell cycle in the absence of notablely increased apoptosis in colon cancer cell lines HT29 and SW620 (S phase arrest in HCT116). Moreover, inhibition of p110β expression increased oxaliplatin-induced cell apoptosis and cell cycle arrest in HT29, HCT116 and SW620 cell lines. In addition, increases of cleaved caspase-3 and cleaved PARP induced by oxaliplatin treatment were determined by immunoblotting in p110β knockdown group compared with normal control group and wild-type group. It is concluded that down-regulated expression of p110β could inhibit colon cancer cells proliferation and result in increased chemosensitivity of colorectal cancer cells to oxaliplatin through augmentation of oxaliplatin-induced cell apoptosis and cell cycle arrest.

With the improvement of sanitation, the infection rate of hookworm is greatly reduced and the severe infected case is rarely reported. Combined morphological and molecular biological examinations, a severe hookworm infection patient was diagnosed in Department of Laboratorial Examination, Quanzhou First Affiliated Hospital of Fujian Medical University. The morphological methods such as direct fecal smear microscopy, saturated brine flotation and hookworm larvae culture methods were used to identify the eggs and larvae from stool samples of the patient. There were a large number of hookworm eggs in patient's stool samples, and the average count was 60 840 per gram by modified Kato method, which belonged to severe hookworm infection. Meanwhile, to distinguish the hookworm species, the semi-nested RT-PCR assay was employed to detect hookworm internal transcribed spacer series from eggs in patient's stool samples, and the result showed that the hookworm species was confirmed to be Necator americanus.
