Objective The objective of this study was to investigate the imaging findings of 18 F-FDG PET-CT in patients with multiple myeloma(MM).Methods Fifteen patients with multiple myeloma were enrolled in our hospital from January 2014 to October 2016.The clinical data of these patients were retrospectively analyzed to obtain the range of SUVmax values by 18F-FDG PET-CT imaging performance.Results Fifteen MM patients with 18F-FDG PET-CT showed a total number of lesions 202,the number of lesions 176 in PET and the number of lesions 171 in CT.The SUVmax range of 18F-FDG PET-CT imaging in the diagnosis of MM was 1.41 ～ 16.28.Fourteen cases of 15 MM patients were found varying degrees of bone destruction;one case showed a slightly increased bone density and also slightly increased FDG metabolic activity.Bone destruction was more performance for the chisel-like,osteolytic,swelling and flaky bone destruction.The osteogenesis lesions were rare.Conclusion 18F-FDG PET-CT imaging can clearly show the imaging features of MM by combining functional metabolic and anatomical information,and provide more clues for clinical diagnosis,which can improve the diagnostic accuracy of MM.

Objective To measure the activity energy expenditure(AEE) of healthy adults during level walking by using indirect calorimetry,and to analyze the characteristics and underlying influencing factors such as age and gender. Methods A total of 60 healthy adults aged 20-50 years (30 males and 30 femdes) participated in the study.All the subjects were divided into six groups by gender and age (the age span of each group was 10 years). The subjects were arranged to walk at speeds of 3.5,4.5,5.5km/h and run at 5.5,6.5,7.5km/h, respectively, on the treadmill. The resting energy expenditure ( REE ) and AEE were measured during walking and running at different speeds.There was a 5-minute rest among the test sessions. Results No difference in terms of AEE between the female and male at the same age ( P ＞ 0. 05 ). During 3.5km/h walking,AEE of 21-30 year-old females was lower than 31-40 yearold females and males( P ＜0.05 ) ;During 4.5km/h walking,AEE of 31-40 year-old females was higher than 21-30 yearold females and males and 41-50 year-old females; AEE of 21-30 year-old females was lower than 41-50 year-old males (P ＜ 0.05 ) ;During 5.5km/h walking,AEE of 31-40 year-old females was higher than 21-30 year-old females and males ( P ＜ 0. 05 ). During 6.5 km/h running, AEE of 31-40 year-old females was higher than 41-50 year-old females ( P ＜0.05), while during 7.5km/h running, AEE of 21-30 year-old males was higher than 41-50 year-old females (P ＜0.05 ). It was also found that the AEE of all groups except the 41-50 year-old females group was higher when walking at the speed of 5.5km/h than running at the same speed( P ＜ 0.05 ). Conclusions Age has more effect on REE and AEE than the gender. AEE of elder subjects is higher than that of the younger ones during walking, however, AEE of younger people increases faster than the elders during running. AEE of 31-40 year-old females is the highest in all groups both in walking and running. AEE in running is higher than in walking at the same speed.

Objective To investigate the therapeutic effect of the Hubei Wingnut ( Malus hapehensis ) leaf decoction (MHD) against conjunctivitis infected with human simplex virus type I (HSV-1). Methods Malus hupehcnsis decoction was used as the active treatment and ribavirin ( RBV) eye drop was used as the positive control. Both of the Vero cells and rabbit eye conjunctiva were infected with HSV-1. The effect and mechanism of the MHD on viral replication was determined by observing the cytopathic effect ( CPE) . The efficacy of MHD at different doses on the rabbit viral conjunctivitis was examined by pathological changes of eye conjunctiva tissues. Results MHD did not inhibit the proliferation of HSV-1 in vitro. The inflammatory reactions of rabbit viral conjunctivitis caused by HSV-1 were obviously attenuated or disappeared after treatment with MHD at 6 kg·L-1 and 3 kg·L-1 for 7 consecutive days,compared with the negative control of 0. 9% NaCl. The curative rate of MHD at the middle and high doses was 83. 3% and 100. 0%, respectively. Conclusion MHD has the potential for treating eye conjunctivitis caused by HSV-1 by relieving inflammation.

Purpose To oberve the dynamics of liver granuloma and the relative changes of Thl/Th2cytokine levels in mice infected with Schistosoma japonicum, and investigate the role of Th1/Th2 in S.japontcum granuloma formation and regulation. Methods Liver granuloma measurement were performedby histological examination and the ELISA were used for the quantitative determination of IL-2, IFNr andIL-4 in murine serum and spleen lymphocyte culture medium at 0,4,6,8,10 and 12 wk after infection.Results At 6 wk liver granuloma formation appeared and at 8 wk liver granuloma peaked. After 12 wk livergranuhoma diminished obviously. Meanwhile, at 4 - 6 wk IL-2, IFNr and IL-4 began to rise, at 8 wk thelevels of Th1 cytokines IL-2 and IFNγ peaked and then declined, and at 8 wk the levels of Th2 cytokines IL-4 were rapidly enhanced and increased obviously with a prolongation of the infection duration.Conclusions The Th1cytokines IL-2 and IFNγ were correlated well with S. japonicum granulomaformation and vigour, and the Th2 cytokines IL-4 might play an important role in down-regulating egggranuloma reaction at chronic schistosomiasis by inhibiting the Th1cytokines.

Objective To investigate the correlation between FA value,ADC value and limb muscle strength score measured by magnetic resonance imaging in patients with ischemic stroke,aims to to analyze the clinical value of magnetic resonance imaging in limb muscle strength.Methods Twenty patients with acute cerebral infarction and treated from June 2015 to Junly 2016 were recruited from This hospital,and the simplified Fugl-Meyer motor function score was observed for all patients within 3 days.Tensor imaging examination was conducted to observe the distribution of nerve fiber bundles,FA value,ADC value changes.Results The FA value and ADC value of the infarct side were significantly different from those of the contralateral side(t=8.70,t=-18.70,P＜0.05);There were significant differences in FA value and ADC value between the infarcted ventricle hind limbs and the contralateral side of the infarcted ventricle(t=-5.16,t=-5.08,P＜0.05).The FA value of the infarcted ventral hind limbs had positive correlation with the simplified Fugl-Meyer motor function score(R=0.863,P=0.013).Conclusion FA value and ADC value of acute infarct and internal hindlimb are lower than FA value and ADC value of contralateral normal white matter.The FA value of internal capsule hind limbs is closely related to the simplified Fugl-Meyer motor function score.

To explore the action target of praziquantel (PZQ) and its underlying mechanism of action, adult male worms of Schistosoma japonicum were collected from the hepatic vein of Kunming mice infected at least 6 or more weeks previously with single-sex cercariae of S.japonicum by perfusion method. These worms were subjected to the action of calcium channel blockers (CCBs) or actin depolymerizing/stabilizing agents interfering with function of the calcium channel. The adult male worms in DMEM culture medium were co-cultivated with near-lethal dose of PZQ(14 μmol/L) overnight(16 hours).Then, the parasites were washed 3 times with sterile physiologic saline next morning after cultivation, re-suspended in new and drug-free medium and then observed under stereo-microscopy during the following 5 days. The experimental results showed that majority of adult male worms of S.japonicum were killed by the action of PZQ in a dose of 14 μmol/L in vitro under normal condition; while the worms pre-incubated with the actin depolymerizing agent cyto chalasin D (CyD) were able to survive in the condition containing 14 μmol/L of PZQ with a survival rate of 100%, and the worms pre-incubted with CCBs, such as nitrendipine and nifedipineu showed a survival rate of about 50% under the same condition. The results of this study suggest that the calcium channel of Schistosomes may be involved in the action target of PZQ and its underlying mechanism.

Objective Because of local infiltrated growth and spread,the operative resection of hilar (cholangiocacinoma) is very difficult. Recently,combined extended hepatectomy and vascular resection had been performed for treatment of hilar cholangiocarcinoma and has greatly increased the resection rate and survival rate.However, it is associated with high operative morbidity and mortality. The aim of this study is to explore a reasonable hepatic resection strategy, that is safe and beneficial for the patient. Method Sixteen (consecutive) cases of hilar cholangiocarcinoma with involvement of hilar vessels have been treated in our hospital since 1977. En bloc resection of the hilar tumor that included hepatic segment I,IV and involved blood (vessel), as well as hepato-duodenal ligament skeletonization was performed in 15 patients. Results All 15 cases were successfully operated on with a resection rate of 93.8%, and 12 cases with R_0 resection. The operative mortality and in-hospital mortality rate were 0. Temporary bile leak and abdominal infection (respectively) developed in 1 patienteach,with an overall morbidity of 13.3%,and both were cured by non-(operative) therapy. No case of liver failure occurred. Follow up showed the median survival was 22 months and 7 are still alive. Conclusions (1)The resection rate and survival rate for hilar cholangiocarcinoma could be improved by combination of liver and hilar vascular resection.(2)Hilar cholangiocarcinoma mainly spreads to the medial segment(S4) and caudate(S1), and these segments need to be resected in the combined (operation).(3)Although resection of the middle part of liver takes little more time than hemi-hepatectomy and trisegmentectomy, it could preserve more liver parenchyma and reduce postoperative morbidity (such as liver failure) and mortality rates.(4)The resection of the hilar blood vessel involved by tumor was necessary to improve the resection rate and cure rate. Reconstruction of the blood vessel was made selectively by taking the circumstances into consideration.
