Objective To evaluate the relationship between relative perfusion rate assessed with power Doppler imaging (PDI) and microvessel density (MVD), as well as expression of vascular endothelial growth factor (VEGF) in bladder carcinoma. Methods The transrectal ultrasound (TRUS) blood flow signal of bladder carcinoma was preoperatively detected with color Doppler imaging in 45 patients, and the relative perfusion rates were obtained for analysis. MVD and the expression of VEGF of excised tumor were assessed immunohistochemically. Results There were correlation between relative perfusion rate and MVD, the expression of VEGF. MVD and the expression of VEGF were related to pathologic grade and the invasiveness of tumor tissues. The expression of VEGF in bladder carcinoma was positively correlated to the tumor interstitial vascular density. Conclusion Combination of PDI and immunohistochemical parameters is useful for evaluating the angiogensis of bladder carcinoma from a different point of view.

Objective To observe the effects of hydrogen sulfide on hepatic and renal injury induced by thioacetamide (TAA).Methods Twenty-four male SD rats were equally and randomly divided into TAA induced model group ,control group,TAA +sodium hydrogen sulfide group , and TAA +propargylglycine group .TAA was given by intraperitoneal injection to the model group , sodium hydrogen sulfide and propargylglycine groups at the dose of 600 mg/kg on the first day, and at the dose of 300 mg/kg 24 hours later.Hydrogen sulfide sodium at the dose of 0.15 mmol/kg and propargylg-lycine at the dose of 30 mg/kg were injected abdominally 1 h before TAA injection.The dose of these two agents was halved in the next 24 h.All the rats were sacrificed and specimens were collected to test hydrogen sulfide , and hepatic and renal function.Urine after the first 24 hours was collected after the administration of TAA .Results The structure of the liver in TAA group was disordered , especially in sodium hydrogen sulfide group .Liver function of TAA group was severely damaged (ALT:980.0 ±32.0 vs 38.3 ±10.6 U/L),and deteriorated with the application of sodium hydrogen sulfide (ALT:1095.6 ± 684.2 U/L), but recovered (ALT:66.3 ±8.32 U/L) with propargylglycine application.Compared with the normal group, the renal function in TAA group was significantly injured ,but the urea nitrogen and creatinine in sodium hydrosulfide group were reduced more remarkably than in TAA group (BUN:8.4 ±1.9 vs 11.62 ±6.0 mmol/L,Cr:32.6 ±8.2 vs 42.8 ±4.4 μmol/L, P<0.05).Nevertheless, creatinine was increased in propargylglycine group ( Cr 56.7 ±14.9 vs 30.8 ±4.4μmol/L, P<0.05).The urine content within 24 hours was more significantly decreased in TAA group than in the normal group (9.2 ±2.5 vs 20.5 ±6.7 ml, P<0.01), which was mildly recovered in sodium hydrogen sulfide group (11.7 ± 1.5 vs 9.2 ±2.5 , P<0.05) but further decreased (4.2 ±1.3 vs 9.2 ±2.5, P<0.01) in the propargylglycine group . Conclusion Hydrogen sulfide can alleviates renal injury while aggravating liver injury induced by thioacetamide .

Objective To observe the development of Schistosoma japonicum after single sexual infection and double sexual infection respectively. Methods A single Oncomelania hupensis snail was infected by a single schistosome miracidium. The lar?va were induced and released from the snail after 60?day incubation at 26℃. The mice were infected by the larva(single sexual infection)and dissected 40 days after the infection. All the worms were collected and the sex of the larvae was determined by the sex of the adult worms. Then,the mice and rabbits were infected by single sex of larvae(single sexual infection)and double sex of larvae(double sexual infection)respectively. The mice and the rabbits were dissected 40 days after the infection. All the worms were collected and measured under a microscope. Results All the male or female worms were collected from the mice and rabbits after single sexual infection. There were three main forms of worms after dissection of double sexual infection of mice and rabbits:folded mature male and female,male or female. Few folded male and immature female were found. Only the double sexual larva infected mice or rabbits had schistosome eggs in the liver and the liver had typical schistosome egg nodules. The sin?gle sexual larva infected mice or rabbits had no schistosome eggs or schistosome egg nodules in the liver tissues. The single male larva could develop to worms with the testis,and with a little smaller size compared to the mature folded male,while the single sexual infection female worm could not develop to the mature stage with much thinner and smaller compared to the mature folded female. Conclusions The male or female worms from single sexual infection are smaller than those from double sexual infection (mature worms?folded male and female). So it is necessary to check single sex worms in vessels of intestinal mucosa thoroughly in the sentinel mice when no schistosome eggs were found in the liver.

Object To study the chemical constituents from the fruits of Juniperus formosana Hayata. Methods The compounds were isolated and purified on liquid-liquid, silica gel, and aluminium oxide column chromatography, their structures were identified by spectroscopic methods, such as GC-MS, 1H-NMR, and 13C-NMR, especially 2D-NMR. Results Two new oxygenated diterpenoids, named labdatriene (Ⅰ) and labdadiene (Ⅱ), were isolated from the ethyl acetate extract. Their structures were determined to be 19-carboxy-8(17)-13(16)-14-labdatriene and 15, 19-dihydroxyl-8(17)-13(E)-labdadiene, respectively. Conclusion Compounds Ⅰ and Ⅱ are new diterpenoids.

Objective To explore the bronchoscopic features of endobronchial tuberculosis induced by lymphatic fistula and the efficacy of interventional treatment. Methods The data on 31 patients with endobronchial tuberculosis induced by lymphatic fistula who had received bronchoscopic diagnosis and treatment in our hospital during the period of January 2010 to June 2013 were reviewed. The bronchoscopic features , along with the frequency of interventional therapies and duration of the therapies , were retrospectively analyzed; and the efficacy of the therapies and the related complications were assessed. Rusults The endoscopic appearance showed: granuloma (19.4%), necrosis (51.6%), granuloma with necrosis (25.8%), and fistulous opening (3.2%). Dark gray matter or carbon deposition inside the lesions was the characteristics of endobronchial tuberculosis induced by lymphatic fistula. There were 76 orificium fistulae in 31 patients , mostly in the right side. The median frequency of treatment was five in patients with single orificium fistulae and the median treatment duration was 65 days; whereas the median frequency of treatment was nine in patients with multiple fistulae and the median treatment duration was 108 days. There were significant differences between the two groups (P < 0.05 for both comparisons). The effectiveness rate of treatment was 98.7%. The therapy-related complication was of a small amount of bleeding, with a rate of 2.1%. Conlusions Endobronchial tuberculosis induced by lymphatic fistula shows certain characteristics under bronchoscopic examination. Bronchoscopic clamping combined with infusions with antituberculosis agents is a safe, simple, effective therapeutic method.

Objective To investigate the occurrence and severity of behavioral and psychological symptoms of dementia(BPSD)in elderly dementia patients,and to explore the relationship of the degree of dementia and the severity of BPSD with the burden of caregivers in pension agency.Methods Using a convenient sampling method,the Clinical Dementia Rating (CDR) scale,neuropsychiatric scale (NPI)and Zarit caregiver burden scale(ZBI)were used to evaluate 145 patients with Alzheimer's disease and caregiver burden in Hangzhou.Results The incidence rate of BPSD was 51.8 ％ (72 cases),with a higher incidence rate of delusions of 22.3％ (31 cases),a higher severity of sleep disorder/nocturnal behavior [NPI symptom score (5.95 ± 4.60) points].The symptom making a greatest burden on the caregivers was delusion [ZBI score (32.81 ± 17.66) points].There were positively correlations of the burden of caregivers with the degree of dementia and the severity of BPSD (r=0.434,0.710,all P＜0.01)in patients with senile dementia.Conclusions The incidence rate of BPSD in dementia patients is higher,and the occurrence of BPSD is associated with the severity of mini mental state examination(MMSE)and dementia,which increases the burden of caregivers.More attention should be paid to BPSD in patients with senile dementia.And the social support system serving patients with senile dementia and their caregivers should be further improved.

OBJECTIVE:To probe into the rational drug use condition in Shenzhen area and to promote the rational drug use level. METHODS: A multi-center randomized parallel test was conducted in 6 different levels of hospitals in Shenzhen area. In which the prescriptions in two months and the outpatients visiting the hospitals on that day were surveyed on the spot in respect of the international rational drug use (RDU) indicators then the data were analyzed statistically. RESULTS: Prescription indicators were as follows: the average number of drugs was 2.44; the percentage of antibiotics prescribed was 43.7%and that for injection was 22.3%. Patient care indicators were as follows: the average consultation time was 6.97 minutes; average dispensing time was 16.77 seconds; percentage of drugs actually dispensed was 100%; percentage of drugs actually labeled was 100%; percentage of patients’ knowledge of correct use of drugs was 96.5%. CONCLUSIONS: The rational drug use level in Shenzhen area is still low and problematic and the care given by doctors and pharmacists to the patients is insufficient, which remain to be improved and tackled.

Objective To evaluate the effect of pelvic muscle exercise on quality of sexual life after panhysterectomy surgery.Methods A retrospective review was made on 166 patients with integrated follow-up documents,after their panhysterectomy surgery caused by benign diseases.A normal nursing care was provided to the control group (n=81); while an additional pelvic muscle exercise was performed on the normal care basis,to those in the experimental group (n=85).Finally,a questionnaire on sexual life quality was made at the sixth month,ninth month,and twelfth month respectively,using a repeated measure ANOVA to analyze the data of each dimension and the whole score.Results Significant differences revealed both on the whole score and dimensions of the sexual satisfaction,sexual communication,sexual anxiety and sexual reaction,in different time sites.However,no difference was found in sexual attitude and body image.Besides,a cross interaction was found between time and intervention,where intervention presented different effects.Conclusions Pelvic muscle exercise is recommended in gynecological continuing nursing care to facilitate the recovery of sexual life after panhysterectomy surgery.

Objective To explore the clinical features,electroneurophysiology,neuroimaging and gene characteristics of one juvenile dentatorubral-pallidoluysian atrophy (DRPLA) pedigree with an onset of epilepsy.Methods The clinical data of the elder sister and younger brother in a family with juvenile DRPLA were collected.Furthermore,their clinical manifestations,electroneurophysiology results,neuroimaging characteristics and atrophin-1 gene CAG repeat numbers were detected and analyzed in detail.Results There were four patients in this family in total.The probands were two siblings,and they both had the onset manifestation of epilepsy.The younger brother had frequently epileptic seizure,marked cerebellar ataxia,involuntary movement and mental retardation.Compared with her younger brother,the sister had light symptoms such as mild memory deterioration without ataxia and involuntary movement,and she could undertake some simple work.The spike wave and sharp wave complex can be detected in electroencephalogram (EEG) examination,the cortical center segment lesions pathological changes were revealed in somatosensory evoked potentials (EP),and the latency period of P300 was prolonged in the both siblings.Magnetic resonance imaging (MRI) showed that the younger brother had marked atrophies in the cerebral cortex,brainstem and cerebellum.Furthermore,MRI showed that the elder sister had only mild atrophies in the cerebral cortex,brainstem and cerebellum,and that on the contrary some abnormally high signals were observed in cerebral cortex but not white matter.DRPLA gene detection revealed that the numbers of CAG repeats were 15/68 (the younger brother) and 15/64 (the elder sister),respectively.Conclusions Epilepsy,especially the myoclonus,is a common clinical manifestation for juvenile DRPLA,and many other types of epileptic seizures may arise with the development of DRPLA.DRPLA has diverse clinical heterogeneity.EEG,EP and brain MRI examination are great for DRPLA diagnosis and differential diagnosis,and the specific gene detection can be helpful for a definitive diagnosis.
