Objective To explore the risk factors, di ag nosis and treatment of renal pelvis and ureter cancer after surgery of bladder c ancer. Methods The clinical data of 13 patients (9 males and 4 females) with renal pelvis and ureter cancer after surgical operation of bladder cancer were retrospectively analyzed.Among them renal pelvis cancer was diagnosed in 9 cases;ureter cancer in 4.Clinical manifestations consisted of gro ss hematuria with flank pain in 11 cases,suspected renal pelvis cancer by ultras ound (US) in 2. Results Among the 13 patients,US,intrave nous urography (IVU) and CT located the focus exactly in 10,8 and all the 13 cas es,respectively.Upper urinary obstruction was diagnosed by US and IVU in 13 and 8 cases,respectively.No image was developed by IVU in 5 cases.CT located the foc us exactly in all the 13 cases;of them 11 cases were definitely diagnosed.Overal l,13 cases were cured and alive during the follow-up period. No recurrence or m etastasis developed.Renal dysfunction occurred in only 1 case (Cr,285 ?mol/L) d ue to the contralateral renal stones. Conclusions Multif ocal bladder cancer and cancerogenic tendency of urothelium may be the risk fact ors of this disease.IVU combined with US is the main diagnostic method for the d isease.CT is recommended for the further examination.Nephroureterectomy is the p referred treatment choice for this disease.

Objective To evaluate the activities of daily living (ADL) and investigate its influential factor in primary angle-closure glaucoma patients.Methods One hundred primary angle-closure glaucoma patients (acute phase) diagnosed definitely from April to October 2014 were collected.The status of sex,gender,education,income were recorded.Barthel Index (BI),Hospital Anxiety and Depression Scale (HADS) and Glaucoma Quality of Life-15 (GQL-15) were respectively used to assess the ADL,anxiety and depression symptoms and visual quality of life in primary angle-closure glaucoma patients.At the same time the factors affecting ADL of primary angle-closure glaucoma were analyzed.Results There were no dysfunction in 12 patients,46 patients with mild dysfunction,32 patients with moderate dysfunction and 10% (10/100) patients with severe dysfunction.BI was negatively correlated with anxiety and depression score,GQL-15 results and disease course (r=-0.819-0.395,P < 0.01),and positively correlated with average monthly income (r=0.453,P < 0.01).There were no correlation with gender,sex and education (r=-0.159-0.172,P > 0.05).Conclusions ADL of primary angle-closure glaucoma patients has varying degrees of dysfunction,and disease course,average monthly income,anxiety,depression and visual quality of life are closely related with it.

OBJECTIVE: To explore the effect of traditional Chinese herbal medicine (TCM) for nourishing liver and kidney, clearing meridians and removing toxic substances, on the neurobehavioral manifestations and the activity of the dopamine D2 receptor in rat with levodopa-induced dyskinesias (LID). METHODS: The rat model of Parkinson's disease (PD) was established by injecting 6-hydroxydopamine (6-OHDA) into right substantia nigra of brain, then, the model of LID in rat was produced by injecting levodopa (LD) and benserazide for 4 weeks. The rats were divided into normal control group, 4-week LD treated group, 4-week LD plus TCM treated group, 8-week LD treated group, and 8-week LD plus TCM treated group, and the effect of the TCM on neurobehavioral manifestations was observed. The radioligand binding assay (RLBA) and Scatchard drawing were used to measure the maximal binding capacity of receptor (Bmax) and equilibrium dissociation constant (KD) of the dopamine D2 receptor in corpora striatum. RESULTS: Compared with the 4-week LD treated group and 8-week LD treated group, TCM could decrease abnormal involuntary movement scores of the rats with LID; the RLBA revealed that the dopamine D2 receptor Bmax significantly increased (P<0.05, P<0.01) and the KD significantly decreased (P<0.05). CONCLUSION: TCM can improve the activity of the dopamine D2 receptor and relieve the symptoms of LID.

Objective To investigate the prevention efficiency of spanishneedles herb eye drops on rabbit model with dry eye syndrome caused by sex hormones decline in peri-menopause. Methods Totally 26 rabbits ( 26 right eyes) with dry eye model were studied,and divided into two groups:group A ( the control group, n=12) and group B ( the spanishneedles herb eye drops group, n=12) ,another two rabbits were used as normal control.The Schirmer I tests (SIT), and corneal fluorescein ( FL) were detected, and the total protein content in tear, amylase activity, lactoferrin and lysozyme contents were measured and confocal scanning microscopy were performed at pre-therapy and 1 week,2 weeks,1 month,2 months after therapy,respectively. Results There were no significant difference in the total proteins,lysozyme,lactoferrin and amylase activity between two groups at pre-therapy (P>0.05).After 2 months treatment, there were statistical differences in all items of group A(P<0.05), and SIT, FL in group B(P<0.05).There were significant differences in all indexes between group A and B at 1 wk,2wk,1mo,2mo after therapy.After 2 months treatment,the mean numbers of corneal basal cell in the group B were significantly lower(3 452±422)than those in the group A ( 4 104 ± 568 ) ( P<0. 05 ) . The mean numbers of the inflammatory cells in the group B ( 42 ± 18 ) were significantly lower than those in the group A(208±69)( P<0.05). Conclusion Spanishneedles herb eye drops has significant prevention effect on dry eye syndrome caused by sex hormones decline in peri-menopause.

OBJECTIVE:To optimize the synthesis process of dapoxetine hydrochloride. METHODS :By chiral synthesis , asymmetric reduction was carried out by using 3-chlorophenylacetone as raw material ,(1S,2R)-(-)-1-amino-2-indanol as catalyst,and borane- N,N-diethylaniline (DEANB) as reducing agent. Then ,it was reacted with α-naphthol etherification, sulfonation,dimethylamine substitution ,and HCl salt formation reaction to obtain the final products. The products were characterized by NMR and MS. The synthesis reaction of intermediate Ⅰ,intermediate Ⅱ,intermediate Ⅲ and the final product were optimized. RESULTS :The final product was dapoxetine hydrochloride with purity of 99.8% and yield of 58.9%. Compared with traditional splitting technology ,the chiral synthesis technology of this study did not need splitting ,and the yield of the technology was significantly higher than that of splitting technology reported in literature (31.9%). The optimized technology reduced the generation of impurities and improved the product quality. CONCLUSIONS :The improved technology has milder reaction conditions ,shorter synthesis route and higher yield.
