Primary Hepatic Carcinoma(PHC)is one of the most common malignant tumors in the world.Nowadays,its incidence and mortality have been still increasing.With regard to the early treatment for PHC,the combined therapy,primarily referred to operation,is considered optimal.For recent decades,with the quick development of ultrasonic therapeutics,High Intensity Focused Ultrasound(HIFU)techniques,which rose newly,has already become a kind of effective and noninvasive substitution therapy for PHC operation therapy as a kind of noninvasive tumor therapy.Now,this literature review aims to summarize the found re- search and clinical research of HIFU therapy for primary hepatic carcinoma.

Objective To discuss the clinical features and related factors of psychosis in patients with Parkinson's disease (PD) and assess the prevalence of psychosis.Methods A total of 82 patients with Parkinson's disease and 69 healthy controls were evaluated by Brief Psychiatric Rating Scale and neuropsychiatric questionnaire.For the PD group,the age at PD onset,type and dose of PD medications,and rapid eye movement (REM) sleep behavior disorder (RBD) were recorded.Unified Parkinson's disease rating scale (UPDRS,parts Ⅱ and Ⅲ) and Hoehn-Yahr staging were used for the evaluation of the severity of motor dysfunction,Hamilton depression scale (HAMD) for emotional state,montreal cognitive assessment (MoCA) for cognition,and scales for outcomes in Parkinson's disease-SLEEP (SCOPA-SLEEP) for quality of sleep.Results The prevalence of psychosis was 36.59％ in PD patients and 2.90％ in the control group.The difference between the two groups was statistically significant (P＜ 0.001).Among the 30 PD patients with PD psychosis meeting the NINDS/NIMH criteria,patients experienced illusions,false sense of presence,hallucinations and delusions was 22.0％,14.6％,29.3％,and 7.3％,respectively.Univariate analysis showed that age,levodopa equivalent dosage,SCOPA-SLEEP scores,and prevalence of RBD were significantly higher in thePDP group [(71.1±6.18),(628.7±283.2),(15.3±7.28),60.00％] than in the PDNP group [(66.6±9.25),(461.1±317.2),(9.7±7.64),28.85％] (all P＜0.05).Multivariate analysis showed that Hoehn-Yahr staging was a protective factor (OR =0.039,95％ CI:0.004-0.402),while sleep disorder was a risk factor (OR=1.157,95％CI:1.015-1.320).The PD patients with more psychotic symptoms were much older and with higher SCOPA-SLEEP scores,which had a statistically significant difference (P =0.0042,P =0.0112).Conclusions The prevalence of psychosis is much higher in PD patients than in healthy controls.PD psychosis is correlated with older age,larger levodopa equivalent doses,higher SCOPA-SLEEP scores,and prevalence of REM sleep behavior disorder.

Objective To investigate the effects of anti-parkinsonian drugs on cytokines(IL-6 and TNF-?) produced by PBMC in PD patients. Methods 25 subjects were divided into 3 groups : normal controls(NC),pergolide and Madopar treated PD patients(P+M group),Madopar treated PD patients(M group). PBMC were cultured in the presence of pure RPMI-1640,RPMI-1640 with ConA and RPMI-1640 with pergolide,respectively. The amount of IL-6 and TNF-? in the culture media was measured by enzyme-linked immunosorbent assay (ELISA). Results IL-6 production amount by PBMC when stimulated with ConA was significantly lower in group P+M and M than in group NC( P 0.05). In group P+M,the concentration of TNF-? was significantly higher in the presence of ConA than in the presence of pure RPMI-1640 and in the presence of pergolide( P 0.05). Conclusions The ability of amount by PBMC of PD elderly patients to excrete IL-6 was significantly decreased in the presence of ConA. Pergolide might arise the excretion of IL-6 by PBMC during the treatment process of PD and at the same time does not arise the excretion of TNF-?,which might be neurotoxic.

Objective To investigate the infection of chlamydiae trachomahs(CT) and myoplasmas in urogenital tract and antibiotic susceptibility of cultured genital myoplasmas.Methods 5095 patients with urogenital tract infection were detected with mycoplasma identification susceptibility testing reagent kit,and the drug susceptibility to eight antibiotics of ureaplasma urealyticum (Uu) and mycoplasm hominid (Mh) were tested by broth microdilution method.And chlamydiae trachomatis was examined by golden standard method.Results In 5095 cases, 417cases(8 2%) were infected with chlamydiae trachomatis, and the infective rate in woman(11 2%) was statistically higher than that in man(6 2%). 1728 cases(33 9%) were infected with mycoplasma, and the infective rate in woman(43 0%) was statistically higher than that in man(28 0%).The cases infected with simple UU(1251,24 6%) were more than that in the cases infected with simple Mh(71,1 4%) and the mixed infected cases(406,8 0%). Drug sensitivity to erythromycin, roxithromycin, josamycin, azithromycin, doxycycline, minocin,ofloxacin, ciprofloxacin in Uu infection were 60 3%,67 5%,73 2%,85 3%,55 7%,40 1%,25 6%,2 7%,respectively;while the mixed infection of Mh and Uu had resistance to the eight antibiotics on the different degree.Conclusions The infective rate of chlamydiae trachomatis and myoplasma in urogential tract and the resistance rates to 8 antibiotics in Hunan province were in a higher level, compared with other area inland. It is necessary to develop antibiotic susceptibility test,in addition to the myoplasma culture for guiding the clinical therapy.

Objective To study the changes of hematological indices of blood donors after 400ml whole-blood donation.Methods Blood specimens of 123 healthy donors were collected before donation,1 day,7 days,1 month,and 3 months after donation.The dynamic changes of WBC,RBC,hemoglobin,hematocrit,Plt,plasma total protein,albumin and blood serum iron were observed.Results After donation,the changes of WBC,Plt,total protein of blood plasma and albumin showed no significant change.The levels of RBC,hemoglobin,hematocrit and blood serum iron returned to normal after 3 months.Conclusion For anyone who meets the health standard of blood donors,to donate 400ml whole blood at 3-month interval is harmless.

Objective To investigate early changes of angiopoietin-2(Ang-2)in multiple trauma patients and assess its clinical significance.Methods Forty-five multiple trauma patients aged 2060 years admitted to the hospital within one hour after injury were randomly divided into three groups according to injury severity score(ISS).Blood specimens were obtained immediately upon arrival in the emergency department and plasma samples were assayed for comparing changes of Ang-2,TNF-a and IL-6.Meanwhile,plasma level of Ang-2 was measured and analyzed under different oxygenation index,shock index and base deficit.Results Plasma level of Ang-2 was positively correlated with ISS(P ＜ 0.01)and was concordant with the plasma levels of TNF-a and IL-6(P＜0.01).Furthermore,plasma level of Ang-2 was elevated upon increase of shock index or decrease of oxygenation index(P ＜ 0.01).Plasma level of Ang-2 was elevated with the increase of base deficit(P ＜ 0.01).Conclusions High level of Ang-2 is a marker of endothelial activation and dysfunction early after trauma.Ang-2 is related tightly with the injury severity,inflammation factors,systemic oxygenation and tissue hypoperfusion and may have a tight relation with pathophysiological development and clinical outcome after trauma.

To explore the safety of ropinirole in the treatment of Parkinson′s disease( PD).A total of 221 PD patients participated in a multi-center,12-week randomized,bromocriptine-controlled,double-blind, double-dummy and parallel-group trial.The safety was assessed on the basis of adverse reactions , blood pressure,pulse,laboratory parameters and electrocardiography recordings.The incidence of adverse reaction was 34.9%in ropinirole group and 34.8% in bromocriptine group.And the frequency of adverse reactions had no inter-group statistical significance (χ2 =0.000,P=0.995).Ropinirole has an excellent profile of safety in the treatment of Chinese PD patients.

A novel series of bis-nicotine derivatives (3a-3i) were designed, synthesized and evaluated as bivalent anti-Alzheimer's disease agents. The pharmacological results indicated that compounds 3e-3i inhibited both acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) in the micromolar range (IC50, 2.28-117.86 micromol x L(-1) for AChE and 1.67-125 micromol x L(-1) for BChE), which was at the same potency as rivastigmine. A Lineweaver-Burk plot and molecular modeling study showed that these derivatives targeted both the catalytic active site (CAS) and the peripheral anionic site (PAS) of AChE. Besides, these compounds could significantly inhibit the self-induced Abeta aggregation with inhibition activity (11.85%-62.14%) at the concentration of 20 micromol x L(-1).
