Objective:To discuss the significance of standardized treatment for cancer pain, according to the Cancer Pain Treat-ment Specification (2011 Edition) issued by the Ministry of Health, PR China. Methods:Clinical data of 126 patients with cancer pain, who were admitted to the Department of Medical Oncology, The Fourth Hospital of Hebei Medical University, were collected to com-pare the improvement of the Numeric Rating Scale (NRS) score, number of breakthrough pain, and quality of life score after treatment. The relationships between different pain grades, disease entities, and treatment effect were analyzed. The influence factors of pain relief were also analyzed by using Logistic regression analysis. Results:1). Following standardized treatment, the improvement rate of NRS score has shown significant differences in pain grading (P=0.001) and gender (P=0.000). However, no significant differences were ob-served between different diseases (P=0.112). The improvement rate of the life quality score and the number of breakthrough pain had no significant difference after standardized treatment. 2). The grading of cancer pain and the disease entities had little effect on cancer pain relief. 3). The anti-tumor treatment and“no distant metastasis”were the independent factors that brought about the decrease in NRS and quality of life scores.“No distant metastasis”(P=0.046) was the independent factor that reduced the number of pain out-breaks. Conclusion: The standardized treatment positively affects the NRS score, number of breakthrough pain, and quality of life score. Patients who received anti-neoplastic therapy and who had no distant metastasis showed significant treatment effectiveness in pain management.

Objective To investigate the appropriate and pragmatic drainage after the breast cancer by radi- cal surgery.Methods 120 patients treated by the radical surgery from July 2003 to July 2005,were divided into the experimental group(ring-like double tubes with negative pressure drainage) and the control group(armpit single tube drainage with pressure bind).The differences between the two groups were analyzed in the same period,respectively sixty cases.Results The outflow of the first three days after operation in the experimental group was more than that in control group(P0.05).The incidence of sinoma and incision delaying healing in experimental group was lower than that in con- trol group(P

OBJECTIVETo discuss whether asiaticosides could effectively reduce the endothelial cell damage as a biochemical modulator, so as to further inhibit the post-stenting intima-media membrane hyperplasia.

METHODHuman aortic smooth muscle cells and aortic fibroblasts were selected and divided into the blank group, the rapamycin group and the asiaticoside group and the rapamycin and asiaticoside group. The expressions of muscle cells and fibroblasts TGF-beta1, Smad7 and I-collagen gene were determined by RT-PCR. The expression quantity of I-collagen protein was assayed by ELISA. The coefficient of drug interaction (CDI) between rapamycin and asiaticoside was calculated. Additionally, 16 Chinese mini-swines were randomly divided into group A and group B. One sirolimus drug-eluting stent of the same type was implanted after the high-pressure pre-expansion of anterior descending artery balloon. After the operation, the group A was intravenously injected with normal saline 30 mL x d(-1). Whereas the group B was intravenously injected with asiaticoside 30 mg x kg(-1) x d(-1)(diluted to 30 mL). The expressions of plasma vWF of the two groups were measured at the 7th and 14th days after the operation. At the 28th day after the operation, tissues of the stented vessel segments were sliced and stained to calculate the vessel area, inner stent area, lumen area and neointima area

RESULTCompared with the control group, the combination group showed significant up-regulation in smooth muscle cells and fibroblast Smad7 gene, down-regulation in TGF-beta, and obvious inhibition of I-collagen gene expression (P < 0.01). As for smooth muscle cells, there was no difference in the expression of I-collagen between the combination group and the rapamycin group, with CDI at 0. 83. As for fibroblasts, there was a significant difference in the expression of I-collagen between the combination group and the rapamycin group (P < 0.05), with CDI at 0.77. Plasma vWF of the group B was significantly lower than that of the group A (P < 0.05) at the 7th and 14th days after the operation. At the 28th day after the operation, no difference was observed in vessel area and stent area between the two groups. However, the lumen area in the group B was significantly larger than that of the group A(P < 0.05), and the neointima area of the group B was significantly smaller than that of the group A (P < 0.05).

CONCLUSIONAs an effective biochemical modulator for rapamycin, asiaticosides could inhibit TGF-beta expression, significantly decrease the synthesis and secretion of extracellular matrix, further inhibit the post-stenting intima-media membrane hyperplasia and reduce the endothelial cell damage by effectively up-regulate the expression of Smad7 protein.

Background Corneal epithelial abrasion results in corneal ulcer and stroma cloudy evenb irreversible visual impairment.Previous drugs for corneal epithelial injury can only alleviate the inflammatory irritation.So it is very important to seek a drug which regulate the growth of corneal epithelium.Objective This study was to investigate the effects of recombinant human BIGH3 protein eye drops on corneal epithelial abrasion.Methods Fifty right eyes of 50 clean adult New Zealand white rabbits were collected.Two rabbits were sacrificed right away following establishment of corneal epithelial abrasion models (0 hour group).The other 48 rabbits were randomly divided into recombinant human epidermal growth factor (EGF) derivative group (positive control group),normal saline solution group (negative control group),0.25％ or 0.5％ recombinant human BIGH3 protein eye drops group.Corneal abrasion models were created with alcohol corrosion method with a defect area of 7 mm2.The corresponding eye drops were used separately in 4 groups for four times per day after operation.Experimental eyes were examined by the slit lamp microscope,and fluorescein vital staining were performed 12,24,36,48,72 hours after operation.Planimetry was performed and the corneal photographs were analyzed with computer software.The rabbits were sacrificed 12,24,36,48 and 72 hours after operation,respectively,and the histopathological examination of corneal tissue was carried out.Results No obvious irritation response was seen after administered of eye drops in the recombinant human EGF derivative group,normal saline solution group,0.25％ and 0.5％ recombinant human BIGH3 protein eye drops groups.Histopathological examination revealed a full-thickness defect of corneal epithelium after modeling.The defect area was gradually smaller with time lapse,and corneal epithelium migrated from periphery toward the center zone.Corneal epithelial cells increased with time lapse.Compared with normal saline solution group,the defect area of corneal epithelium lessened 12,24,36,48 hours after operation in the 0.25％,0.5％ recombinant human BIGH3 protein eye drops groups and recombinant human EGF derivative group (all at P =0.000),but at 12and 24,36 hours after operation,no significant differences were found between the recombinant human EGF derivative group and normal saline solution group (P =0.321,0.057,0.126).The defect area was smaller in the 0.5％recombinant human BIGH3 protein eye drops group than that of the recombinant human EGF derivative group at various time points (P=0.042,0.039,0.025,0.008).However,significant smaller defect area was exhibited only at 12 hours and 24 hours after operation in the 0.25％ recombinant human BIGH3 protein eye drops group (P=0.047,0.042).No significant differences were seen in corneal defect area at various time points between 0.25％ and 0.5％recombinant human BIGH3 protein eye drops groups (P =0.358,0.259,0.108,0.062).In addition,the corneal defect area was (0.51 ±0.42)mm2 72 hours after operation in the normal saline group;while that in the recombinant human EGF derivative group and recombinant human BIGH3 protein eye drops groups was disappeared.The repairing curves in the recombinant human BIGH3 protein eye drops groups were superior to those of the recombinant human EGF derivative group and normal saline solution group.Conclusions 0.25％ and 0.5％ recombinant human BIGH3 protein eye drops have facilitation effect on the growth of corneal epithelial cells and the healing of corneal injury.

AIM: To study the effect of phototherapeutic keratectomy (PTK) on rabbit bacterial corneal ulcer model and explore the clinical potential of this method. METHODS:Totally 48 eyes from all the 24 New Zealand rabbits were inoculated with Staphylococcus aureus and bacterial corneal ulcer model was established successfully. At 1d after inoculation,48 eyes were given levofloxacin eye drops when corneal ulcer was confirmed. Then slit lamp inspection and optical coherence tomography ( OCT) were performed to measure the central corneal ulcer depth. All the rabbits right eyes were treated with PTK, as an observation group,left eyes were not treated as a control group. The eye section were observed by slit lamp and central thickness of corneal ulcer was measured by OCT at 3 and 7d after this operation. Rabbits were sacrificed and the cornea was removed for pathological section 7d later. RESULTS: The corneal ulcers in both groups had a tendency to heal, showing a decrease in ulcer area and smoothness of the surface. There was no significant difference in the depth of corneal ulcer between the observation group and the control group before PTK (t=0.706,P=0.484). The difference between the two groups of eyes at 3 and 7d after PTK was obviously (P<0.05). CONCLUSION: PTK can effectively cure rabbit Staphylococcus aureus corneal ulcer and promote ulcer wound healing,which may be used for clinical treatment of patients with bacterial corneal lesions.

Male sterility affects human reproduction seriously. Modern medicine has not yet fully understood the reasons for abnormal sperm, so clinical treatment is mainly based on experience, but the effect is inaccurate. According to "kidney controls reproduction" and "chronic illness causes blood stasis" theory, Professor JIN Bao-fang treats abnormol speerm sterility by tonifying kidney and activating blood circulation to remove obstruction with modified Yangjing Decoction, which has achieved good efficacy.

Objective To explore the biological exposure limit of liver dysfunction induced by arsenic-coal burning, and screen sensitive biornarkers for its' liver dysfunction monitoring. Methods One hundred and eighteen subjects from the exposed area and 50 control from non-pollution area were studied. Their urinary and hair contents of arsenic were tested as exposure biomarkers by Ag-DDC assay. Total bile acid(TBA, detected by enzymatic cycling method), glutathione S-transferase (GSTs, detected by chemical colorimetry) and γ-glutamyl transpeptidase (γ-GT, detected by colorimetry of diazotization reagent) were used as biomarkers indicating liver cell damage. were used as liver fibrosis biomarkers. The benchmark dose (BMD) and the lower confidence limit of benchmark dose(BMDL) of urinary and hair arsenic were calculated. Sensitivity of each biomarker was estimated according to the BMD and BMDL value. Results The geometric mean of urinary and hair arsenic(98.50 mg/kg Cr, 7.42 mg/kg) μg/L) in the exposed group were significantly higher than urinary and hair arsenic (22.98 mg/kg Cr, 1.28 mg/kg) and each biomarker in the control group(4.63 μmol/L, 13.76 U/L,36.45 U/L,54.62 μg/L,74.45 μg/L,54.81 μg/L, P<0.01). Significant dose-effect relationship existed between urinary and hair arsenic contents and each biomarker. BMD and BMDL value of urinary arsenic was 49.53-101.96 mg/kg Cr and 39.02-70.15 mg/kg Cr, respectively. Those of hair arsenic were 3.04-5.02 mg/kg and 2.36-3.25 mg/kg, respectively. According to BMD and BMDL value of urinary and hair arsenic, the sensitivity of biomarkers decreased in the order of GSTs, TBA and Conclusions According to the lowest BMD and BMDL of urinary and hair arsenic, averaged reference value of urinary and hair arsenic in the local normal population, we suggest urinary 35.0 mg/kg Cr and hair 2.5 mg/kg as their biological exposure limits for those with liver dysfunction induced by arsenic-coal burning. GSTs, TBA, γ-GT and HA, Ⅳ. C, PC-Ⅲ can respectively reflect liver cell damage and liver fibrosis caused by arsenic-coal burning in different degrees, among which, GSTs and HA are the most sensitive biomarkers respectively for liver cell damage and liver fibrosis.

OBJECTIVETo study the feasibility and effect of substituting esophagus with stomach or colon without thoracotomy in the treatment of cervical esophageal carcinoma with laryngeal function preserved.

METHODSTwenty-four patients with cervical esophageal carcinoma were retrospectively reviewed. The esophagus was resected and substituted with 19 gastric pull-up and 5 colon interposition. Nineteen patients received radiotherapy postoperatively (dose 50 - 70 Gy).

RESULTSTwenty two patients were follow up over 3 years. The 3- and 5-year survival rates for T2 were 3 and 1, for T3, T4 8 and 3, respectively. The laryngeal function preservation rate was 77% (17/24) and the decannulation rate was 75% (12/16). The complication rate was 29%.
