Objective To evaluate peri-operative clinical effects of transurethral electrovaporization of the prostate(TUVP) combined with transurethral resection of the prostate(TURP) versus open prostatectomy for benign prostatic hyperplasia(BPH).Methods A total of 156 cases of BPH were surgically treated in this hospital from November 1997 to December 2004,including 53 cases of TUVP combined with TURP(Combination Group) and 103 cases of open suprapublic prostatectomy(Open Group). Results There were no significant differences in the operation time between the two groups(90?70 min vs 108?68 min;t=(-1.550),P=0.123).The Combination Group was superior to the Open Group in the blood transfusion rate(8% vs 38%;?~2=16.109,P=0.000),the time to clear urine(2?1 d vs 4?1 d;t=-11.831,P=0.000),the postoperative catheterization time(10?8 d vs 19?10 d;t=-5.680,P=0.000),the time to get out of bed(6?4 d vs 20?10 d;t=-9.785,P=0.000),and the postoperative hospital stay(20?14 d vs 34?24 d;t=-3.914,P=0.000).The incidence of complications was higher in the Combination Group than in the Open Group(15.1% vs 2.9%;?~2=6.173,P=0.013).Conclusions TUVP in combination with TURP for benign prostate hyperplasia has advantages of little invasion and rapid recovery.

Entamoeba is a zoonotic protozoan that can parasitize in the intestine and other organs in human and animals . There are many species in this genus ,but only Entamoeba histolytica can cause amebic colitis and liver abscess ,and even death .The cysts and trophozoits are difficult to be discriminated for pathogenic and nonpathogenic Entamoeba .And there is al-so difference in the pathogenicity ,infectivity etc .,even in the same species .Therefore ,it is difficult to confirm the Entamoeba species according to traditional method ,thus affecting the use of medicine .In this article ,the research progress of molecular examination and genotyping method about entamoeba are reviewed .

OBJECTIVE:To establish a method for the content determination of AV45(the labeled precursor of PET agent for Aβ plaques)and its related substances. METHODS:HPLC method was performed on the column of Inertsil C18 with mobile phase of 50 mmol/L Disodium hydrogen phosphate solution- acetonitrile(containing 0.01% triethylamine)(15∶85,V/V)at a flow rate of 1.0 ml/min,the detection wavelength was 325 nm,and column temperature was 30 ℃,and volume injection was 20 μl. RESULTS:The AV45 and reaction intermediate as well as individual impurity peaks were well separated;the linear range was 200-1 000 μg/ml for AV45(r=0.999 2)and 20-100 μg/ml for intermediate(r=0.999 6);the detection limit and quantification limit of reaction in-termediate AV45 were 0.1 ng and 0.5 ng,respectively;RSDs of precision,stability and reproducibility tests were lower than 0.5%;recovery of AV45 was 98.93%-101.58%(RSD=0.69%,n=9). CONCLUSIONS:The method is simple and accurate with high specificity and good reproducibility,and suitable for content determination of AV45(the labeled precursor of PET agent for Aβplaques)and its related substances.

Objective To evaluate the changes in noxious stimulation intensity at different periods of pneumoperitoneum in gynecological laparoscopic surgery. Methods Forty-five ASA Ⅰ orⅡ patients, aged 25-36 yr, with body mass index 18-23 kg/m2 , undergoing elective gynecological laparoscopic surgery, were randomly divided into 3 groups ( n = 15 each) . In group Ⅰ , anesthesia was maintained with TCI of remifentanil (target plasma concentration 4-6 ng/ml) and propofol (target plasma concentration 2 μg/ml) , and the concentrations were ad-justed according to the changes in BP and HR to maintain hemodynamics stable. Ⅱ and Ⅲ groups received inhala-tion of isoflurane (end-tidal concentration 1%-2%) and TCI of remifentanil (target plasma concentration 2-4ng/ml) . TCI of remifentanil was then stopped at 5 min before pneumoperitoneum (group Ⅱ ) or at 5 min after theend of rapid inflation (group Ⅲ ) , and isoflurane was inhaled (end-tidal concentration 1%-2% ) to maintain anes-thesia until the end of operation in Ⅱ and Ⅲ group. Before anesthesia (T0 ), 5 min before pneumoperitoneum (T1), 5 and 15 min of pneumoperitoneum (T2,3), HR and MAP were monitored and venous blood samples were taken for determination of plasma cortisol (Cor) , norepinephrine ( NE) and epinephrine ( E) concentrations. Results HR, MAP and NE and E concentrations at T2,3 , and Cor concentrations at T3 were significantly higher than those at T0 ingroup Ⅱ , and in group Ⅱ than in group Ⅰ (P<0.05). HR, MAP and NE and E concentrations at T2,3 ,and Cur concentrations at T3 were significantly lower in group Ⅲ than in group Ⅱ ( P < 0.05). Conclusion The intensity of noxious stimulation is strongest during rapid inflation among the different periods of pneumoperitoneum in gynecological laparoscopic surgery and the depth of anesthesia should be regulated.

Purpose To investigate the clinicopathological features,diagnosis and differential diagnosis of myxoid synovial sarcoma (MSS).Methods Clinicopathological changes and immunophenotype were retrospectively evaluated in two MSS cases collected from Fujian Provincial Hospital,conbined with genetic mutation analysis.The relevant literatures were reviewed to explore its clinical and pathological features of this tumor.Restilts The two cases,one man and one woman,aged 71 and 15years,respectively.Tumor was located in the left down abdomen in case 1,and left frontal temporal lobe in case 2.Histopathologically,at low magnification in case 1,the tumor was nodular,which was made up of areas of hypercellularity and hypocellularity.In some areas of hypocellularity,the tumor cells were arranged in fascicular,story-form,sheet arrangements with mucoid degeneration.In hypercellularity area,the tumor cells were arranged in fascicular,fish bone-liked arrangenents.At low magnification in case 2,the tumor was nodular,which was made up of areas of hypercellularity and hypocellularity.In hypocellularity area,the tumor cells were arranged in net-like,sheet arrangements,and fascicular,sheet arrangements in case 2.In some area,the tumor cells were epithelioid with cluster distribution,without infringing brain tissue.Immunohistochemically,the tumor cells were diffusely positive for BCL-2,vimentin,and α-SMA and EMA were partially positive,while CD34,CD57,S-100,CD117,PLAP were negative.However,in case 2,only BCL-2 was positive,and MyoD1,GFAP,Olig-2,EMA,Syn,CD99,CgA,S-100,Myogenin,STAT6,CD34,desmin and α-SMA were negative.Molecular detection SYT-SSX fusion gene was detected in both cases.Conclusion MSS is a rare malignancy of soft tissue.The diagnosis of MSS depends on molecular pathology.The clinical and pathological findings are different from mucinous fibrosarcoma and solitary fibrous tumor.The treatment is surgical resection,combined with radiotherapy,with poor prognosis.

OBJECTIVE:To observe the clinical efficacy and safety of Shenfu injection combined with Danshen chuanxiongqin injection in the treatment of chronic pulmonary heart disease patients with heart failure. METHODS:Totally 100 chronic pulmonary heart disease patients with heart failure were randomly divided into observation group and control group. Patients in control group were given routine treatment,including antispasmodic asthma,low-flow oxygen therapy,anti-inflammatory,diuretic strong heart, maintaining the body water,electrolyte balance,vasoactive drugs and dopamine,etc. Patients in observation group were given Shenfu injection 50 ml and Danshen chuanxiongqin injection 10 ml adding into 5% glucose injection 250 ml based on the treatment of control group,iv,once a day. The course of both was 14 d. The clinical data was observed,including clinical efficacy,improve-ment time of signs and symptoms,p(O2),p(CO2),SV,LVEF,LVEDD,LVSD and the incidence of adverse reactions before and after treatment. RESULTS:The total effective rate in observation group was significantly higher than control group,the remission time of cyanosis,slowing time of heart rate and subsided time of swelling were significantly shorter than control group,with signif-icant differences(P<0.05). After treatment,the p(O2),p(CO2),SV,LVEF,LVEDD and LVSD in 2 groups were significantly bet-ter than before,and observation group was better than control group,with significant differences(P<0.05). There were no obvious adverse reactions during treatment. CONCLUSIONS:Based on the treatment,Shenfu injection combined with Danshen chuanxion-gqin injection has better clinical efficacy than routine treatment in the treatment of chronic pulmonary heart disease patients with heart failure,with similar safety.
