Purpose: To study the clinical application of intensity modulation radiation therapy (IMRT) in patients with prostate cancer. Methods: From May 2000 to June 2001, 14 patients with prostate carcinoma were treated . 12 patients underwent orchiectomy before IMRT. All patients were treated by IMRT with PEACOCK-MIMiC system ( CORVUS 3. 0 NOMOS CORPORATION) and VARIAN 6MV-photons. The prescription dose-time- fraction was 2.5 to 3. 0 Gy per fraction, 5 times per week , the total was 25 to 30 fractions, the total IMRT dose was 72 to 77 Gy, 5 to 6 weeks. Results: 3 months after IMRT , PR: 10(71.4%), NC: 4 cases and 6 month after IMRT CR: 6,PR: 8 cases. The overall response( CR + PR) rate were 100% . No Grade Ⅲ ,Ⅳ gastrointestinal ( GI) and genitourinary ( GU) toxicity occurred in any of the patients. Conclusions: IMRT is an effective approach for patients with prostate carcinoma. The dose of 72 to 77 Gy was safe.

Cancer stem cell (CSC) theory supposes that CSCs are the origin of tumors occurrence, progression,drug resistance, recurrence and metastasis. Cancer is not only a genetic disease but also a stem cell disease. Increasing evidence suggests the existence of CSCs in some solid tumors.

Objective To observe the clinical effect of HuaYu TongFu KaiQiaoFang on serum homocysteine (Hcy)in patients with acute cerebral infarction. Methods Sixty cases of acute cerebral infarction admitted into the comprehensive ward and intensive care unit(ICU)of the First Affiliated Hospital of Guiyang College of Traditional Chinese Medicine from December 2010 to January 2012 were randomly divided into two groups,each group including 30 cases. The control group was given conventional treatment,and based on the conventional therapy,the treatment group was additionally given HuaYu TongFu KaiQiaoFang(a traditional Chinese medicine decoction including the following ingredients:Safflower 10 g,Chishao 10 g,Chuanxiong 10 g,Notoginseng 10 g,Angelica Sinensis 10 g, Shichangpu 10 g,Polygalae 10 g,Glauber's salt 5 g,Rhubarb 6 g),one dose a day by oral or nasal administration for consecutive 14 days. Before and after treatment in the two groups,the serum Hcy level was detected by enzyme-linked immunosorbent assay(ELISA),and the clinical efficacy was assessed by Pearson or Spearman correlation analysis to observe the correlation between neurological deficit score(NDS)and Hcy levels. Results Before treatment, the difference of serum Hcy(μmol/L)and NDS levels between the two groups was not statistically significant(both P>0.05),while after treatment,the levels in the two groups were significantly decreased in comparison with those before treatment(P<0.05 or P<0.01),and the degree of descent in treatment group was more obvious compared with that in control group(Hcy:7.78±2.51 vs. 10.18±2.41,NDS:10.60±2.25 vs. 14.60±3.70,both P<0.05). After treatment,the total effective rate in the treatment group was significantly higher than that in the control group (90.0%vs. 76.7%,P<0.05). Before treatment,the NDS was positively correlated with Hcy(r=0.675,P<0.05). Conclusion HuaYu TongFu KaiQiaoFang can significantly reduce the level of serum Hcy and improve the nerve function,thus its clinical effect for treatment of acute cerebral infarction is remarkable.

Objective To compare the effect and safety between cemented and uncemented long-stem hip arthroplasty for treatment of unstable intertrochanteric fracture in the elderly.Methods A retrospective review was made on 70 cases (70-87 years old) undergone artificial long-stem hip arthroplasty of unstable intertrochanteric fracture between June 2012 and June 2014.According to the material of prostheses,the cases were assigned to cemented group (n =36) and uncemented group (n =34).Operation-related index,postoperative complications,ambulation time,Harris hip score and prosthesis stability and excellent results were compared between the two groups.Results There were no significant differences in operation time,bleeding volume and ambulation time between the two groups (P > 0.05).Postoperative drainage volume and blood transfusion volume in cemented group [(277.4 ± 22.0) ml and (245.1 ± 17.8) ml] were lower than these in uncemented group[(294.2 ± 33.7) ml and (262.8 ± 30.9)ml] (P <0.05).Harris scores in cemented group were higher than these in uncemented group 1 and 3 months after operation(P <0.05),and there were no significant differences 6 and 12 months after operation(P > 0.05).Complication rate had no significant difference between the two groups (P > 0.05).Two cases were died of cement poisoning,one case of subsequent acute myocardial infarction,and two cases of subsequent acute cerebral infarction.Sixty-five cases were followed up for 12-36 months,which showed no complications such as prosthesis loosening,displacement or infection.Prosthesis stability and treatment excellent rate between the two groups were not significantly different (P > 0.05).Conclusions Clinical efficacy of the two treatments is comparable,including good function recovery and early off-bed activity.Cemented long-stem hip arthroplasty reduces blood requirements,but the risk of cement poisoning exists.

Objective: To develop new kinds of stationary phases suitable for applications in capillary electrochromatography (CEC), as well as in LC, which can be tailored to realize selective separations of solutes difficult to separate with conventional stationary phases. Methods:Purchased spherical silica particles (5 ?m) were refluxed in anhydrous toluene with vinyl triethoxysilane for 18 h, to modify the surface with vinylsilyl groups. The silylated silica particles were subsequently stirred in an n henanol acetonitril mixture (1∶4, volume fraction) for 18 h. Styrene and divinylbenzene in the mixture co polymerized to form a crosslinked encapsulation layer on the silica surface, and bonded on the surface vinyl groups at the same time, both reactions were initiated by azo iso butyronitrile. The poly(Styrene divinylbenzene) encapsulated silica(PS DES) produced can be used as a non conventional stationary phase for CEC itself. By sulphonation of the PS DES phase with chlorosulphonic acid, strong cation exchange stationary phase of sulphonic type was obtained. Results: The manufactured PS DES as well as the sulphonated phases were respectively packed into capillaries,and the columns thus prepared were tested for their chromatographic characteristics. It was found that the PS DES phase showed reversed phase characteristics. Due to the phenyl groups in the encapsulated polymer, it introduced ?-? electronic interaction between the solutes molecules and stationary phase during the chromatographic separation process, therefore it showed unique selectivity on separating aromatic compounds, also polar as well as some alkaline drugs was analyzed on the column packed with the phase. It was demonstrated that the sulphonated phase could be used to prepare columns for the separation of alkaline drugs, symmetric peaks were obtained for them and base line separation was realized. Conclusion: It is possible that these stationary phases prepared can be used for solving the analytical problems in which non conventional selectivity are needed ( the analyses of alkaline drugs are examples) In some cases, the analysts can realize the anticipated separation results based on the different separation mechanism from that of the conventional stationary phases.
