Objective To investigate the clinical study of sarcoside combined with tamsulosin in the treatment of type Ⅲ prostatitis. Methods 84 patients with type Ⅲ prostatitis who were treated and diagnosed in Jishuitan Hospital from November 2015 to December 2016 were randomly divided into experimental group and control group according to the time of hospitalization, 42 cases in each group. The control group was treated with tamsulosin hydrochloride sustained-release capsules, and the experimental group was treated with the addition of the new drug. The maximum urinary flow rate and mean urinary flow before and after treatment were recorded, compared and analyzed before and after treatment. Results The maximum urinary flow rate and mean urinary flow rate were increased in both groups after treatment, and there was significant difference between the two groups (P<0.05). The data of the maximum urinary flow rate and the mean urinary flow rate in the experimental group were significantly better than those in the control group. The data of the two groups were statistically significant (P<0.05). In addition, the experimental group after treatment of prostate symptom score was significantly better than the control group score, the two groups of data were significantly different, the data were statistically significant (P<0.05). In addition, the total effective rate of the experimental group was significantly higher than the control group(80.95%vs. 73.81%). The data were statistically significant (P<0.05). Conclusion The clinical efficacy of sorbenaside combined with tamsulosin in the treatment of type Ⅲ prostatitis is better than that of the original treatment. The treatment can improve the patient's urination and prostate symptoms and improve the patient's comfort.

OBJECTIVETo evaluate the clinical effects of single posterior debridement, bone grafting, internal fixation and local chemotherapy in treating thoracolumbar spinal tuberculosis.

METHODSFrom February 2009 to September 2012,11 patients with thoracolumbar spinal tuberculosis were treated by single posterior debridement, bone grafting, internal fixation and local chemotherapy. There were 7 males and 4 females, aged from 27 to 65 years old with an average of 53.7 years. The courses of disease was from 3 months to 2 years with the mean of 9 months. According to ASIA standard of spinal cord injury, 3 cases were grade C and 8 cases D. After treatment, clinical effects were evaluated by ASIA grade, visual analogue score (VAS) and Oswestry Disability Index (ODI); kyphosis Cobb angle change was observed by X-rays.

RESULTSEleven patients were followed up from 12 to 29 months with an average of 18 months. ASIA grade of spinal cord injury, 3 patients with grade C improved to grade D in 2 cases and grade E in 1 case 8 patients with grade D improved to grade E in 7 cases and unchanged in 1 case. VAS decreased from preoperative 6.10 ± 1.30 to 1.70 ± 0.80 at 3 d after operation (P < 0.05). ODI improved from preoperative (68.36 ± 10.41)% to (14.55 ± 8.99)% (P < 0.05) at 3 d after operation. Kyphotic Cobb angle was corrected from preoperative (22.64 ± 4.84)° to (4.27 ± 1.49)° (P < 0.05) on the 3rd day after operation, and angle loss was mild at final follow-up, there was no significant difference between postoperative at 3 d and final follow-up.

CONCLUSIONSingle posterior debridement, bone grafting, internal fixation and local chemotherapy for the treatment of thoracolumbar spinal tuberculosis can effectively remove the lesion, improve nerve function and correct deformity, has advantage of single incision, little trauma, and low recurrence rate. But it still need long-term and systemic treatment with anti-TB drugs.

ObjectiveTo evaluate the therapeutic efficacy and prognostic factors of intensity-modulated radiotherapy combined with chemotherapy for early-stage nasopharyngeal carcinoma patients in northwest China. MethodsFrom January 2006 to December 2009,58 patients with early-stage nasopharyngeal carcinoma were treated with IMRT in Xijing hospital,the clinical data were analyzed retrospectively.Survival rates was calculated by the Kaplan-Meier method and the differences was compared by the Logrank test.Univariate analysis method was use to identify all significant factors.ResultsThe follow-up rate was 100％.The follow-up time of 46 patients was more than 3 years.The 1-,2 and 3-year survival were 98％,94％ and 91％,respectively.The 3-year overall survival (OS),local recurrence-free survival (LRFS),distant metastasis-free surv ival (DMFS) for T1N0-1,T2N0 and T2N1 stage were 100％,100％,100％ and 74 ％,81％,87 ％,respectively ( x2 =5.74,P =0.01 ; x2 =4.95,P =0.03 ; x2 =4.24,P=0.04).The 3-year OS,LRFS,DMFS for IMRT combined with chemotherapy and IMRT alone were 100％,100％,100％ and 85％,85％,88％ respectively ( x2 =4.02,P =0.04; x2 =4.12,P =0.03 ; x2 =4.84,P =0.02).In T2N1 stage,IMRT combined with chemotherapy and IMRT alone were 100％,100％,100％ and 79％,79％,80％ respectively (x2 =5.28,P =0.03 ;x2 =4.84,P =0.04;x2 =4.72,P =0.04).In univariate analysis,N stage,clinical stage,IMRT combined with chemotherapy were significantly associated with the survival ( x2 =5.39,P =0.02 ; x2 =5.74,P =0.01 ; x2 =4.02,P =0.04).Conclusions In all early-stage nasopharyngeal carcinoma,T2N1 stage is a sub-group of high risk of distant metastasis.Combination of IMRT and chemotherapy may improve the LRFS,DMFS and OS in those patients.

OBJECTIVETo tentatively establish a diagnosis and treatment mode for effectively controlling the progress of cerebral microlesions (CM) and preventing the incidence of cerebral infarction (CI) by comparing different intervention modes for treating CM.

METHODSUsing a prospective, nonrandomized, controlled trial, 408 subjects with multiple CM were assigned to the Chinese medical pharmacy intervention group (Group A, 100 case), the aspirin intervention group (Group B, 104 cases), the negative control group (Group C, 100 cases), and the non-intervention group (Group D, 104 cases). No intervention was given to those in Group D. Patients in the other 3 groups were intervened by life style and routine therapies of vasculogenic risk factors. Those in Group A took Guizhi Fuling Pill (GFP) and earthworm powder additionally. Those in Group B took aspirin additionally. They were routinely followed-up. The CM, the changes of vasculogenic risk factors, and the incidence rate of CI were compared among the 4 groups.

RESULTSThe total effective rate of CM was 66.67% in Group A, obviously higher than that of Group B (52.32%), Group C (42.86%), and Group D (37.04%), respectively. It was obviously higher in Group B than in Group D, showing statistical difference (P <0.01, P <0.05). After treatment, the serum levels of LDL-C, TC, and TG were obviously lower in Group A than in Group B (P <0.05); the serum levels of LDL-C and TC were obviously lower in Group A than in Group C (P <0.01); the systolic pressure was obviously lower in Group A than in Group D (P <0.05). The systolic pressure and the serum TC level were obviously lower in Group C than in Group D (P <0.05). The incidence rate of CI was 2.17% (2/92 cases) in Group A, obviously lower than that of Group C (11.36% ,10/88 cases) and Group D (14.44%, 13/90 cases), showing statistical difference (P <0.05). But there was no statistical difference between Group A and Group B (6.74% ,6/89 cases) (P >0.05).

CONCLUSIONSGFP combined earthworm powder could treat CM, control vasculogenic risk factors, and finally prevent the incidence of CI. Standard Chinese medical intervention mode showed the optimal effects in treating CM and preventing the incidence of CI, and perhaps it could be spread clinically.

OBJECTIVE: To explore the geomorphological performance, the characteristics of volume, and the largest signal intension of blood oxygenation level dependent functional magnetic resonance imaging (BOLD-fMRI) in brain tumors located in or closed to the central area. METHODS: We recruited 13 normal volunteers and 31(13 benign tumors and 18 malignant tumors) patients with brain tumor located in or closed to the central area, to examine both side hand motor and tactile function by BOLD-fMRI and obtained the activation map and its superposition image with T1 imaging, the volume, and the largest signal intension of the functional area by SPM software which manipulated the raw data in the off-line work station. The volume and the largest signal intension data of the functional area were statistically analyzed by SPSS 13.0. RESULTS: The volume and the largest signal intension of the activation map in the normal functional area had hemisphere advantage. There was difference in the activated signal pixel number and the largest signal intension of the functional area between the benign brain tumors, malignant brain tumors, and the normal volunteers (P < 0.05). The shape, anatomic location, the volume, and the largest signal intension of the functional area were changed in the patients with brain tumors. CONCLUSION BOLD-fMRI is a valid method to assess the pre-surgical risk of patients with brain tumors, which can get the volume, the largest signal intension, the basic shape,and the anatomic location of the functional area.

OBJECTIVETo determine the autocrine effect of vascular endothelial growth factor (VEGF) on epidermal keratinocytes HaCaT cells.

METHODSCultured HaCaT cells were treated with various concentrations of VEGF(165) (0,1,5,10,25,50,100 ng/ml) or Avastin (0,0.063,0.125,0.25,0.50,1.0,2.0 mg/ml) in vitro. HaCaT cell proliferation was determined by MTT assay and the cell migration was measured by migration assay. The effect of VEGF(165) (10 ng/ml) on phosphorylation of ERK1/2 was detected in HaCaT cells pretreated or not pretreated with Avastin (0.5 mg/ml).

RESULTSVEGF enhanced the proliferation and migration of HaCaT cells in a dose-dependent manner, while Avastin inhibited the effects of VEGF also in a dose-dependent manner. VEGF(165) (10 ng/ml) induced the phosphorylation of ERK1/2 in HaCaT cells,but which was blocked by Avastin (0.5 mg/ml).

CONCLUSIONVEGF enhanced the proliferation and migration of HaCaT cells in a dose-dependent manner, while Avastin inhibited the effects of VEGF also in a dose-dependent manner. VEGF(165) (10 ng/ml) induced the phosphorylation of ERK1/2 in HaCaT cells,but which was blocked by Avastin (0.5 mg/ml).

BACKGROUNDWork in voiding (WIV) of the bladder may be used to evaluate bladder status throughout urination rather than at a single time point. Few studies, however, have assessed WIV owing to the complexity of its calculations. We have developed a method of calculating work capacity of the bladder while voiding and analyzed the associations of bladder work parameters with bladder contractile function and bladder outlet obstruction (BOO).

METHODSThe study retrospectively evaluated 160 men and 23 women, aged >40 years and with a detrusor pressure at maximal flow rate (PdetQmax) of ≥40 cmH2O in men, who underwent urodynamic testing. The bladder power integration method was used to calculate WIV; WIV per second (WIV/t) and WIV per liter of urine voided (WIV/v) were also calculated. In men, the relationships between these work capacity parameters and PdetQmax and Abrams-Griffiths (AG) number were determined using linear-by-linear association tests, and relationships between work capacity parameters and BOO grade were investigated using Spearman's association test.

RESULTSThe mean WIV was 1.15 ± 0.78 J and 1.30 ± 0.88 J, mean WIV/t was 22.95 ± 14.45 mW and 23.78 ± 17.02 mW, and mean WIV/v was 5.59 ± 2.32 J/L and 2.83 ± 1.87 J/L in men and women, respectively. In men, WIV/v showed significant positive associations with PdetQmax (r = 0.845, P = 0.000), AG number (r = 0.814, P = 0.000), and Schafer class (r = 0.726, P = 0.000). Conversely, WIV and WIV/t showed no associations with PdetQmax or AG number. In patients with BOO (Schafer class > II), WIV/v correlated positively with increasing BOO grade.

CONCLUSIONSWIV can be calculated from simple urodynamic parameters using the bladder power integration method. WIV/v may be a marker of BOO grade, and the bladder contractile function can be evaluated by WIV and WIV/t.

ObjectiveTo evaluate the long term outcomes, toxicities and prognostic factors of the patients in Northwest China with nasopharyngealcarcinoma (NPC)treated by intensity-modulated radiotherapy (IMRT). MethodsFrom January 2006 to December 2009, 133 NPC Patients were treated by IMRT in Xijing Hospital, the Fourth Military Medical University. There were 22 treated by radiotherapy alone, 111 treated by platinum-based current chemo-radiothreapy. The prescription dose to the gross tumor volume was 66 - 76. 6 Gy/30 - 33 fractions, positive lymph nodes was 66. 0 - 72. 4 Gy/30 - 33 fractions.The higher and lower risk clinical target volume were irradiated with 56. 0 - 63. 5 Gy/28 - 33 fractions and 50. 4 -53. 2 Gy/28 fractions respectively. ResultsThe follow-up rate was 97. 7％. Follow-up time more than 2years,3years were 37cases ,44cases. The l-,2-and 3-year overall survival (OS) were 93. 8％, 88. 3％and 83.2％ ; local control rate were 99. 2％ ,95.4％ and 95.4％ ; regional control rate ( RC ) were 99. 2％,96. 8％ and 96.8％ ; and distant metastasis-free rate (DMFR) were 82. 8％, 79. 8％ and 79. 8％ ; the disease-free survival (DFS) were 84. 3％ ,76. 7％ and 76. 7％, respectively. Multivariate analyses revealed that N stage, age and anemia before radiotherapy were independent predietors for OS (x2 =5.56,9. 10,4.89,P=0. 018,0.003,0.027), and N stage was also independent predictors for DFS (x2 =8.98,P=0.003).Thegrade 3acutetoxicitiesweremueositis(34.7％),xerostomia(20. 1％ ), skin reaction ( 1.4 ％ ) and leucocytopenia ( 1. 4 ％ ). No grade4 acute and late toxieities were detected. Conclusions IMRT with or without chemotherapy achieved good long term survival in nasopharyngeal carcinoma treated by intensity-modulated radiotherapy, especially in LC and RC. Distant metastasis becomes the main treatment failure.N stage, age, and anemia before radiotherapy were the main prognostic factors in nasopharyngeal cancer patients.

OBJECTIVETo compare the concentrations of IgA, lactate dehydrogenase, lysozyme and alkaline phosphatase (ALP) in unstimulated (UWS) and stimulated (SWS) whole saliva between children with severe early childhood caries (S-ECC) and children without caries.

METHODSOne hundred and ninety-two children aged from 42 to 54 months were recruited from 11 urban kindergartens in Beijing. The S-ECC group contained 98 children with more than 5 decayed teeth, and the control group contained 94 caries-free children. The age and sex were matched in the two groups. Two milliliter UWS and 2 ml SWS was collected between 9 and 11 a.m. The salivary IgA was measured by immunoturbidimetric technique. The concentrations of lactate dehydrogenase and ALP were measured by continuous monitoring method, while lysozyme was detected by turbidimetric technique. All results for paired observations between unstimulated and stimulated whole saliva were analysed by paired-samples t test.

RESULTSIn both UWS and SWS, the concentrations of IgA, lactate dehydrogenase and lysozyme in S-ECC children were higher than those in caries-free children (P < 0.01), but the concentration of ALP showed no significant difference in SWS between S-ECC children and caries-free children (P > 0.05).

CONCLUSIONSThe presence of early childhood caries may be associated with an increase of IgA, lactate dehydrogenase and lysozyme in unstimulated and stimulated whole saliva.

OBJECTIVETo investigate the role of Src kinase inhibitor ZD6474 on the growth of multidrug-resistant K562/A02 cells and its regulatory mechanisms.

METHODSThe possible mechanisms of drug-resistance were tested by Western blot. Proliferation assays and cell cycle distribution were analyzed by WST metric analysis. Western blot were used to investigate the mechanisms of antiproliferative activity induced by tyrosine kinase inhibitor ZD6474. The in vivo anti-tumor activity was evaluated in K562, K562/A02 xenografted nude mice by administration of ZD6474 (25 - 100 mg×kg(-1)×d(-1), PO).

RESULTSCompared with parental K562 cells, marked high levels of p-Src and Src expression were detected in K562/A02 cells. WST results showed that the IC(50) values of ZD6474 on K562 and K562/A02 after 48 hours incubation were (1.61 ± 0.07) µmol/L and (3.22 ± 0.21)µmol/L, respectively. ZD6474 caused an accumulation of cells in the G(0)/G(1) fraction and apoptosis by inhibiting the expressions of p-Src and Src kinase. Administration of ZD6474 produced a dose-dependent inhibition of tumor growth. 50 mg/kg ZD6474 produced the growth inhibition rates of 43.7% and 56.3%, respectively in K562 and K562/A02.

CONCLUSIONOur results indicated that inhibiting Src kinase could induce K562/A02 cells apoptosis in vitro and in vivo.
