One hundred seventy of patients with cervical esophageal carcinoma (30 cases were treated by pre-operative radiation and surgery (combined group), 27 cases by surgery alone, 113 cases by radical radiation). The doses of the preoperative radiation and the radiacal radiation were D T40 Gy/4w and above D T 50 Gy/5w, respectively. The 5 year survival rates were 40% in the combined group, 15.3% in surgry alone, and 28% in radical radiation groups. The difference of survival rates in the combined group and surgery alone was significantly different statistically. Factors affecting the survivals were lymphnode metastasis in radical radiation and recurrent larygeal nerve paralysis in the combined group. The main causes of failure were local residual and recurrence (71%) in radical radiation and lymphnode metastasis (81%) in the combined group. The authors believe that pre-operative radiation combined with surgery could improve the survival of cervical esophageal carcinoma. Radical radiation is also one of effective treatment methods for cercical esophageal carcinoma.

Objective To evaluate the value of fractionated stereotatic radiation therapy (FSRT)(X knife) as a boost for recurrent or residual nasopharyngeal carcinoma (NPC) at the primary focus. Methods From Sept.20, 1995 to Dec.30,1998, 50 such patients were treated by FSRT with 6 MV photons. The total FSRT dose was 24~30?Gy prescribed at 1~4 centers on the 60%~90% isodose curves normalized to isocenter by multifractions of fraction size 6~8?Gy, 12,15?Gy, with interfraction duration of 4~6 days. Results CR 38/50 (76%), PR 9/50 (18%) and in evaluated 3/50 (6%). Total survivals(Kaplan meier):1 yr 83.6%, 2 yr 65.0% and 3 yr 59.6% . Conclusion Fractionated stereotatic radiotherapy (FSRT) is strongly indicated for recurrent or residual NPC at the primary focus.

Objective: To observe the effect of Juebi capsule (JBC) on experimental prostatic hyperplasia. Methods: Experimental prostatic hyperplasia was induced by castration testicular nourmone in the mice and rats respectively and the isolated bladder trigone muscle of the rabbit was used for contraction inhibition. Results: For mice, JBC 10 20g/kg was administered intragastrically for 10 days; for rats, JBC 1 2g/kg was taken for 3 weeks. The results showed that JBC can significantly inhibite prostatic hyperplasia and decrease wet weight of the gland, DNA content and the activity of serum acid phosphatase. Otherwise, 0.25%, 0.50% and 0.75% water suspension of JBC also can inhibite the contraction induced by norepinephrine in isolated bladder trigone muscle of the rabbit. The inhibition rates were 29.17%, 41.72% and 62.29%.Conclusion: JBC can significantly inhibit experimental prostatic hyperplasia and decrease contraction of bladder trigone muscle induced by ? adrenoceptor agonist.

Objective To observe the clinical manifestation and pathological immunohistochemical features of intraspinal extramedullary peripheral primitive neuroeetodermal tumour (PNET). Methods From Apr. 1996 to Aug. 2007, totally 5 patients with intraspinal extramedullary peripheral PNET were treated, including 3 male and 2 female, aging from 11 to 48 years. The primary site was cervical vertebral in 2 (C5-C7 and C5-T1 ) and thoracic vertebral in 4( T4-T6, T6-T8 ,T4-T5 and C5-T1 ). The clinical manifestation was paresis of limbs in 5 and incontinence in 4. All the patients were pathologically diagnosed Results All of the three patients who had CD99 staining expressed CD99 ( + ). All the 5 patients received surgery followed by radiotherapy and 4 received postoperative chemotherapy. The most common treatment failure was local recurrence. The overall survival time of the 5 patients was 4.8year,2.5year,2. 1ycar, 1.6year and 0.8 year respectively. Conclusions Intraspinal extramedullary peripheral PNET is highly malignant tumor.Patients have very poor survival and local control New treatment protocol should be studied to improve the local disease control and increase remission rate. To distinguish central PNET from peripheral PNET has crucial significance since different entities have different treatment protocol and prognosis.

Objective To explore the short and long term curative effects of percutaneous transhepatic cholangioscopic lithotomy (PTCSL) in the treatment of intrahepatic stone (IHS).Methods 38 IHS patients were enrolled,who were treated with PTCSL between January 2008 and July 2013.Results PTCSL was successfully completed in all the 38 IHS cases.Stone clearance rate was 84.2% and the average episode of stone removal was (2.6 ± 0.9) times.Average diameter of percutaneous transhepatic fistula was (18.4 ± 0.6) F and the average time from percutaneous transhepatic puncture and fistulization to cholangioscopic lithotomy was (7.2 ± 0.7)d.The average operation time was (68 ± 20) min,intraoperative blood loss was (20 ± 13) ml,and hospitalization was (4 ± 2) days.The hepatolith recurrence rate in patients with stones completely removed was 37.5% (12/32),and 1 case developed into biliary cirrhosis.Patients with calculi residual suffered from higher hepatolith recurrence rate of 83.8% (5/6),with biliary cirrhosis found in 1 case.Conclusions PTCSL is safe and effective in treating primary IHS,which is indicated in multiple recurrent IHS especially in after biliary surgery patients.It has the advantages of minimally invasion,less bleeding,less postoperative pain,less complications,and fast postoperative recovery.

Objective: To explore the effects of monocrotaline (MCT) on right ventricular function and expression of cardiac canonical transient receptor potential channels (TRPC) subfamily in experimental rats.
Methods: The SD male rats were randomly divided into 2 groups:Control group, the rats were normally fed and MCT group, the rats received a single dose injection of MCT 60 mg/kg to induce myocardial hypertrophy. n=10 in each group and all animals were treated for 3 weeks. The right ventricular hemodynamics parameters and right ventricular hypertrophy index (RVHI) were measured, right ventricular myocardium tissue section was observed by HE staining, the mRNA and protein expressions of TRPC subfamily were examined by RT-PCR and Western blot analysis.
Results: Compared with Control group, MCT group had increased RVSP, RVHI, RV+dp/dtmax and decreased RV-dp/dtmax, all P<0.01. In MCT group, the right ventricular myocardial cells had the thinker ifber, deeply stained nuclei with irregular shape. Compared with Control group, the mRNA and protein expressions of right ventricular TRPC6 were elevated in MCT group, n=6 and n=4 respectively, all P<0.05.
Conclusion:Right ventricular hypertrophy could be induced by 3 weeks MCT treatment, it up-regulating the mRNA and protein expressions of TRPC6 which might be involved in the occurrence and development of cardiac hypertrophy in experimental rats.

Objective To study the effect of plant Coleus forskohlii active elements Isoforskolin(ISOF)and CT-E(analogs mixture of Isoforskolin)on human neutrophill(PMN)in vitro in order to uncover the mechanism of their properties of mitigating acute lung injury(ALI).Method The effects of ISOF and CF-E on PMN aggregation induced by N-formyl-methiony-leucyl-phenylalanine(fMLP)was performed by using a 4-channel platelet aggregometer.Cytometry Was applied to analyze the effect of tested samples on adhension between PMN and endothelial cells(ECV-304)activated by using lipopolysaccharides(LPS).Expression of LPS-induced PMN adhension molecules was determined with flow cytometry.Radioimmunoassay Was applied to detect the level of TNT-α liberated bv PMN and intracellular cyclic adenosine monophosphate(cAMP)level of PMN.Results It was found that ISOF(25,50,100 μmnol/L)and CF-E(1.25,2.5,5 mg/ml)inhibitted PMN aggregation induced by fMLP,PMN adhemion to ECV-304 indeed by LPS,expression of PMN adhesion molecules,and TNF-α level released by PMN.ISOF and CF-E also increased intracellular cAMP level of PMN.Condusions ISOF and CF-E inhibit PMN aggregation,adhension and adhension molecules,and TNF-α released by PMN,while they increase intracellular cAniP level of PMN.It suggests that their specific alleviating the ALI by the mechanism of the modulation of PMN function.
