Objective To analyze the volumetric and dosimetric variations in radiation treatment planning(RTP) using CT images based on normal and extended reconstructed field-of-view(FOV). Methods Original data of CT scans from 16 cases of nasopharyngeal carcinomas were reconstructed to form 2 sets of CT images with Dermal(45 cm)and EFOV(65 cm),which were then exposed to RTP. Contouring of targets/OAR including GTV(gross tumor volume),CTV(clinical target volume,CTV),brain stem, lens, parotids and cord was made on normsl FOV CT set.A 7-field equi-angular IMRT (intensity modulated radiation Therapy)plan was generated with prescribed GTV dose of 70 Gy.Two sets 0f CT images were fused in DICOM coordinate system and targets/OARs on normal FOV CT were copied to EFOV CT.IMRT plans were then transplanted from normal FOV to EFOV CT,with the same isocenter on DICOM coordinates.Volumetric and dosimetrie variations including GTV,CTV brain stem,lens, parotids and cord were calculated on dose-volume-histogram(DVH).For dosimetric verification,IMRT plans were input into fluence maps of Mapcheck 1175 phantom based on normal FOV and EFOV, and DTA(distance to agreement)was used to analyze the passing rate of calculated/measured absolute doses at 5 cm depth.Paired-t test was used to compare the passing rate of field 1-7 of IMRT plans based on 2 CT sets.Results Volumes of targets and OARs on 2 CT sets of different FOVs were statistically different.with larger calculated volume on norlual FOV in all cases.There was no statistic difference in the maximal(Dmax) doses received by all targets and OARs except the small-volume lens, in which the dose was higher on normal CT than that on EFOV CT(t=-3.14,P<0.007).The mean doses(Dmean)to the CTV(clinical target volume)and GTV(gross tumor volume)were higher on EFOV than normal FOV CT(t=-6.45,-5.65,P<0.001).There was no statistic difference in Dmean received by OARs and the minimal dose (Dmin)by all targets and OARs(P>0.05).There was also no statistic difference in the passing rate of field 1-7 of IMRT plans based on 2 CT sets.Conclusions There were volumetric and dosimetric variations as evaluated on DVH using different reconstructed FOV during CT simulation,though the difference between the passing rates as verified in 2 dimensional fluence map was not significant.

Objective To investigate the clinical efficacy and indication of surgical treatment of L5S1 tuberculosis us?ing a medial edge of rectus abdominal muscle and retroperitoneal approach. Methods From Jan. 2010 to Nov. 2014, totally 18 cases of L5S1 tuberculosis were surgically cured by debridement, fusion and internal fixation via a medial edge of rectus ab?dominal muscle and retroperitoneal approach. There were 10 males and 8 females, with an average age of 35.6±10.1 years (21 to 55). The mean course of disease was 5.3±2.2 months. The primary destruction lesions were located at L5S1, and one patient of whom L4 was also involved, three cases S2 involved, and one S3 involved. Abscess pre sacrum was noticed in all cases. Six patients were combined with abscess in vertebral canal. Neural deficiency was detected in 3 patients, all grading as Frankel D. Dubousset's lumbosacral angle was 104°-126°, mean 114.6°±6.0°. Formal anti?tuberculosis medicine treatment was given for at least 2-3 weeks. All patients were treated using a medial edge of rectus abdominal muscle and retroperitoneal approach. Af?ter debridement, a tri?cortical iliac bone was used for structural inter?vertebrae fusion. The iliac bone was fixed to the sacrum by one cortical screw. Operation time, volume of blood loss, and surgery complications, including wound infection, looseness and shift of internal fixation, sinus occurrence, vascular injury, retrograde ejaculation in male patients were evaluated. The X?ray and 3D CT of lumbosacral spine, together with ESR and CRP were used to evaluate the control of tuberculosis during fol?low?up. The Dubousset's lumbosacral angle, visual analogue score, and the Frankel grade were compared between preoperative and postoperative. The bone graft fusion were also observed. Results The operation time was 147±16 min in average. The mean blood lose was 275 ± 77 ml. No vascular or neurological injury was noticed. There was also no retrograde ejaculation happened in this group. All patients were followed up from 18 to 28 months. Dubousset's lumbosacral angle was 122.4°±3.8° post?operatively and 121.4°±3.7° at the final follow?up. There was a significant difference between the lumbosacral angles pre and post operation, whereas no statistical difference between the post operation and the final follow?up. Bone fusion was noticed in all cases. All pa? tients have intact neurological function at the final follow?up. No screw breakage or graft bone migration occurred. VAS was 5.6± 1.09 pre?operation and 0.83±0.71 at the 3rd month's follow?up, and there was a significant difference between them. Conclusion Surgical treatment of L5S1 tuberculosis by debridement, fusion and internal fixation via a medial edge of rectus abdominal muscle and retroperitoneal approach is an effective method in terms of minimal trauma, low rate of modality, good ability in restore and maintenance of lumbosacral junction alignment and high fusion rate.

Objective To compare the pharmacodynamics of rocuronium intermittently administered according to body surface area and real body weight and individual differences. Method Forty-two patients undergoing elective surgery under general anesthesia were enrolled into the body surface area group (BSA group) and the real body weight group (RBW group), with 21 patients in each group. The patients in the two groups were induced with 2ED95 of rocuronium according to body surface area and real body weight (16.64 mg/m2 in BSA group; 0.6 mg/kg in RBW group). Whenever T1 recovered to 10%, a dosage of 0.5ED95 was administred repeatedly for 30 min before the end of the operation. The time of neuromuscular blockade and recovery of muscle relaxation were recorded, and the dosage of rocuronium was also recorded. Results No significant difference in each index of neuromuscular block time-effect was found between the two groups (P > 0.05). The single dosage and maintainance amount of muscle relaxation were less in the BSA group than that in RBW group (P < 0.05). Compared with the RBW group, the single dosage, dosing intervals, pharmacological duration and the time TOFr recovered to 0.7 between the different individuals were less in the BSA group (P < 0.05). Conclusion The intermittent administration of rocuronium can maintain the same clinical efficacy according to body surface area as that according to real body weight , with significantly less dosageand reducing the differences of individuals in blockade time-effect of muscle relaxation.

Objective To analyze the epidemiologic features of visceral leishmaniasis in different age groups in China from 2005 to 2012,and to provide a scientific basis for prevention and treatment of the disease.Methods The visceral leishmaniasis cases were obtained from China disease epidemic monitoring information system from 2005 to 2012.All the cases were divided into subgroups by demographic characteristics:infant (＜1 year old),childcare (≥1 and ＜4 years old),child (≥4 and ＜15 years old),adult (≥15 and ＜65 years old) and senior adult (above 65 years old).The epidemiologic features,such as gender,season of disease onset and area distribution of visceral leishmaniasis were analyzed.Results The total reported visceral leishmaniasis from 2005 to 2012 were 2 979,among which cases in infant,childcare,child,adult and senior adult were 24.9％,21.7％,20.0％,32.4％ and 1.0％,respectively.Infant cases were most reported in April; childcare cases in December which began to increase since September; child cases in October and adult and senior adult in March.The reported cases were mainly from Xinjiang,Gansu and Sichuan areas.However,age characteristics differed among regions,which were mainly infants,both childcare and children,and adults,respectively in this three areas.The duration from onset to diagnosis was shortest in infant group (11 d) and longer in adult group (15 d).Conclusions The number of visceral leishmaniasis cases in different age groups peaks in different months.Regional distribution is not even.Cases are most concentrated in Xinjiang,Gansu and Sichuan areas.Infants predominate in Xinjiang,childcare and children in Gansu and adults in Sichuan.

Objective To analyze the investigation data of the national schistosomiasis surveillance sites in 2015,so as to provide scientific evidences for schistosomiasis control,elimination and surveillance. Methods According to National Schisto-somiasis Surveillance Programme(version 2014),457 surveillance sites were selected,and the investigation data in residents, floating population,domestic animals and Oncomelania hupensis snails were collected and analyzed from four types of endemic counties. Results A total of 4468 seropositive cases were detected from 133350 residents,among which 4457 residents with seropositive results received the etiological tests,and 71 of them were identified with positive results. Most of them were fisher-men and farmers in the middle and old-aged group. The schistosomiasis infection rate was 0.05% in local population. Totally 977 seropositive cases were examined from 85047 migrant individuals,and 16 positive cases were found out from 966 individuals who took etiological tests,which showed the schistosomiasis infection rate was 0.02% in floating population. Imported cases were found among floating people in four provinces,namely Zhejiang,Hunan,Hubei and Anhui provinces. No acute schistoso-miasis cases were reported. A total of 13406 head of cattle received examinations and only 5 were determined as stool positives. The cattle infection rate was 0.04%. The snail survey covered an area of 22295.13 hm2 and snails were found in an area of 7426.63 hm2,including 3.47 hm2 newly detected area with snails. No schistosome-infected snails were found. Conclusions Based on the collected data from 457 national schistosomiasis surveillance sites of China,the Schistosoma japonicum infection rate is 0.05% in local population which maintains a stably descending trend. In floating population,there are imported schistosome-in-fected persons. Cattle are still a vulnerable species infected with schistosome. Although no infected snails are found,snails are widely distributed in endemic areas. Some provinces detect areas with snails for the first time or the reproduction of snails. The staff in endemic provinces should carry out the surveillance work according to National Schistosomiasis Surveillance Programme (version2014)to improve the surveillance system,and enhance the sensibility and effectiveness of surveillance work.

Objective To investigate the effects of the interaction between human hepatoma cells and hepatic stellate cells on their growth state,and study its role of interaction on the progression of hepatocellular carcinoma.Methods Human hepatoma cell line HepG2 and hepatic stellate cell line hepatic stallate cells (HSC)-T6 were used and the methods including methyl thiazolyl tetrazolium (MTT) assay,flow cytometry (FCM) analysis,immunohistochemistry,and electron microscopy were employed in this experiment.The effects of conditioned medium (CM) of HepG2 on the activation and proliferation of HSC were explored.The effects of activated HSC CM on HepG2 proliferation were investigated.The uhrastructural changes of the two co-cultured cells were observed.Results MTT assay result showed that HepG2/HSC CM could promote HSC/HepG2 proliferation.FCM result demonstrated that HepG2/HSC CM could influence the cell cycle distribution in HSC/HepG2.Immunohistochemistry exhibited that after the treatment of HepG2/HSC CM,the expression ofα-smooth muscle actin (α-SMA) in HSC and proliferating cell nuclear antigen (PCNA) in HepG2 were increased.When HepG2 and HSC were co-cultured,the ultrastructure of HSC displayed an activated feature.Conclusions HepG2 cells can induce the activation and proliferation of HSC,and the activated HSC can also stimulate the proliferation of HepG2.Interaction between hepatoma cells and hepatic stellate cells may play an important role in the progression of hepatocellular carcinoma.

Objective To analyze the optimal scales of secondary public hospitals so as to optimize the expansion of public hospitals.Methods Forty-six secondary public general hospitals in Beijing were selected as the sample,with input and output indicators pinpointed,for analysis of the status of economic return to scale of such hospitals from 1996 to 2012,and identification of inflexion points of the returns to scale.These efforts will help find an optimal scale of such hospitals.Resalts The period from 1996 to 2012 found the general effectiveness of such hospitals in a decline.In 2012,only 4 of the 46 hospitals were in DEA effectiveness status,and the other 42 hospitals were not; Forty-three inflexion points were identified.This study found that the strict control standards for secondary public general hospitals in Beijing were 298 beds and 585 staffs; the flexible control standards were 421 beds and 807 staffs.Conclclsion The optimal scales for secondary public hospitals were drown from the analysis,for references of other regions in China.The hospitals should prioritize resources efficiency instead of scale expansion.
