Objective To investigate the efficacy and toxicity of conventional fractionated three-dimensional conformal radiotherapy (3D-CRT) on unresectable hepatocelluar carcinoma(HCC).Methods Fifty two patients with unresectable HCC,all without extrahepatic metastases,were treated by 3D-CRT conducted 5 times a week with the total radiation dose of 36-66 Gy and a daily dose of 2 Gy.The curative effect was evaluated by CT scan to observe the maximum tumor size.Survival rates,survival time,and adverse responses were recorded.Results The total effective rate of the 52 patients was 69.2％ with complete response (CR) in 2 patients and partial response (PR) in 34 patients.The incidence rate of radioactive hepatitis was 1.92％.The 1-,2-,3-,and 4-year survival rates were 57.7％,34.6％,23.1％,and 9.61％ respectively,and the median survival time was 10.5 months.The 1-,2-,3-,and 4-year local control rates were 67％,51.5％,32.3％,and 2.24％,and the 1-,2-,3-,and 4-year distant metastasis rate were 17.2％,23.5％,36.7％,and 76.9％ respectively.The intrahepatic metastases rate was 62.5％ and 37.5％ of the patients suffered from extrahepatic metastasis,including metastases of lung,bone,and retroperitoneal lymph nodes.The remission rate of the≥50 Gy group was 76.9％,significantly higher than that of the ≤50 Gy group (46.2％,x2 =10.72,P ＜ 0.05 ).There was no grade 3 or 4 acute toxicity,and two patients (3.84％) developed gastric or duodenal ulcer.Conclusions Conventional fractionaled 3D-CRT evokes a rather effective response for unresectable HCC with acceptable toxicity.Radiation dose seems to be a significant prognostic factor in RT response for HCC.

AIM:To observe the pathological changes of the lower segment of nasolacrimal duct mucosa in rabbits at different stages after retrograde lachrymal dilated drainage tube implantation.
METHODS:Totally 14 New Zealand rabbits were used in the present study. One side of nasolacrimal duct was obstructed to produce an experimental model and operated the reverse implantation of nasolacrimal duct intubation. Histological changes of the lower segment of nasolacrimal duct mucosa were observed by routine light microscope at 2, 4, 6, 8, 10, 12 and 14wk after the operation.
RESULTS: Compared with the control side, the group of 2 and 4wk after surgery presented the inflammatory cytokine. The group of 12wk after the operation presented isolated granuloma. Group 12 and 14wk presented scattered granuloma. The size of the granulomas was smaller and the density of epithelioid cell and fibroblast were lower in group 12wk than those in group 14wk by HE and Masson trichrome stain.
CONCLUSION:Recurrent Silicone Tube is used to treat nasolacrymal duct obstruction. Nasolacrimal duct can be narrowed and blocked again by granuloma, progressive fibrosis and adhesion of surrounding tissues when tube is in the duct more than 12wk.

ObjectiveTo discuss the experimental method and the mechanisms on treating diseases by acupuncturing the ST36(Zusanli).MethodsUsing Positron Emission Tomography(PET) and functional Magnetic Resonance Imaging(fMRI) to obtain the experimental data about glycometabolism and cerebral blood stream,using SPM and ROI image-analytical method to obtain the visual experimental evidence when acupuncturing the ST36. ResultsThere are certain increases of glycometabolism and cerebral blood stream in ipsilateral hypothalamus and bilateral temporal lobe, when acupuncturing the ST36. Conclusions Acupuncturing the ST36 can lead to the functional changes in vegetative nerve center and temporal lobe, which is close correlated with the therapeutical effects of ST36.

Abstract: Objective To research the relationship between promoter polymorphism-438 A/G of thrombin-activatable fibrinolysis inhibitorgene (TAFI-438 A/G) and atherosclerotic cerebral infarction (ACI) in Chinese Han population. Methods TAFI-438A/G genotypes andtheir allele frequencies were identified with the polymerase chain reaction and restriction fragment length polymorphism (PCR-RFLP) in225 ACI patients and 184 healthy controls. Results There was no significant difference of TAFI-438A/G polymorphism between ACI groupand control group. Stratified by gender, in males, the incidence of A allele was 28.6% in ACI group, and 20.6% in control (P=0.039); of theAA genotype was 9.0% in ACI group, and 1.9% in control (P=0.019). But no significant difference was found in females. ConclusionTAFI-438A/G polymorphism is associated with the risk of ACI in males, that AA genotype may increase the risk of ACI.

OBJECTIVETo analyze the complications of percutaneous kyphoplasty except bone leakge for the treatment of osteoporotic thoracolumbar vertebral compression fractures.

METHODSFrom October 2008 to October 2012,178 patients with 224 osteoporotic vertebral compression fractures were treated with percutaneous kyphoplasty under local anethsia. There were 72 males and 106 females,ranging in age from 58 to 92 years old,with an average of 75.3 years,including 93 thoracic vertebrae and 131 lumbar vertebrae. The complications except bone cement leakage were analyzed during operation and after operation.

RESULTSAll operations were successful and all patients were followed up from 12 to 60 months with an average of 26.2 months. No death was found. Bone cement leakage occurred in 27 cases, about 15.1% in 178 cases; and complications except bone cement leakage occurred in 15 cases. There was 1 case with cardiac arrest,was completely recovery by cardiopulmonary resuscitation (CPR) immediately; and 1 case with temporary absence of breathing,was recovery after treatment. There were 3 cases with fall of blood pressure and slower of heart rate; 1 case with intestinal obstruction; 2 cases with local hematoma and 1 case with intercostal neuralgia. Vertebral body fractures of 2 cases were split by bone cement and the fractures of adjacent body occurred in 4 cases.

CONCLUSIONIt's uncommon complication except bone cement leakge in treatment of osteoporotic thoracolumbar vertebral compression fractures with percutaneous kyphoplasty. The complication of cardiopulmonary system is a high risk in surgery; and cytotoxicity of bone cement,nervous reflex,fat embolism and alteration of intravertebral pressure may be main reasons.

Objective To develop an early-warning indicator system of brucellosis outbreak. Methods The methods of literature review and expert discussion were used to formulate the initiatory framework and indicators, and then Delphi method was used to filter indicators, discuss the boundary of indicators and determine the weighting coefficient. Results The average length of service provided by experts who engaged in prevention and control of brucellosis was (25.10 ± 8.80) years and the positive coefficient of the consultant experts of the two-round results were 95% and 68%, respectively. Kendall coefficients were 0.35, 0.54 and X2R value were 81.31 and 285.27, respectively and P value was all less than 0.01. Five first-level indicators(the host animal, high-risk groups,social environment, index case and the level of previous disease) and 13 secondary indicators were selected to develop the early-warning indicator system of brucellosis outbreak. The weight coefficients of the five first-level indicators were 0.21, 0.22, 0.17, 0.21 and 0.19, respectively. Conclusions The early-waming indicator system of brucellosis outbreak is initially established. We propose to develop the early-warning programs according to local conditions and the indicator system.

Objective To study the self-rated health on aged chronic kidney disease for outpatients.Methods The self-rated health evaluation sale(SRHMS V1.0) was used to measure the health for50 aged chronic kidney disease for outpatients and 50 common aged population (retired people). Results The significant difference was noted in the daily physical activities, physical mobility, total score of physical health subscale,positive emotion,cognitive function, total score of psychosocial health subscale, role activity, social resource and social contact, total score of social health subscale and total score of SRHMS V1.0 between the senior chronic nephritis patient and common senior population( P ＜0.05) ;but no differences in the physical symptom and organic function, psychosocial symptom and negative emotion, social support ( P ＞ 0.05 ).

OBJECTIVETo observe the improvement in post-stroke dysphagia after treatment of nape acupuncture and rehabilitation training.

METHODSEighty patients who were in compliance with the inclusive criteria were randomized into a conventional treatment group and a nape acupuncture group, 40 cases in each one, according to the admission sequence. In the conventional treatment group, on the basis of general medication, the rehabilitation training of swallowing function was applied. In the nape acupuncture group, on the basic treatment as the conventional treatment group, nape acupuncture group was given.

RESULTSAfter treatment, the improvements in bedside water swallowing test, SSA, VFSS and pharynx transit time were all superior to those before treatment for the patients in the two groups (all P < 0.05). The improvements in bedside water swallowing test, SSA, VFSS and pharynx transit time in the nape acupuncture group were all superior to those in the conventional treatment group (all P < 0.05). The total effective rate was 85.0% (34/40) in the nape acupuncture group, which was higher than 65.0% (26/40) in the conventional treatment group, indicating the significantly statistical difference between the two groups (P < 0.05).

CONCLUSIONNape acupuncture combined with rehabilitation training significantly improves swallowing function of the patients after stroke.

OBJECTIVETo investigate an effective method to facilitate the physical and mental recovery of drug abusers in detoxification restoration period.

METHODSIntegrated interventions were adopted to observe the changes in the physical and mental conditions of female drug abusers who had withdrawn drugs.

RESULTSComparing behavioral changes between the two groups before and after intervention, we found that changes of score in the intervention group were all higher than those in the control group in terms of their physical symptoms or state of anxiety.

CONCLUSIONIt is necessary to help drug abusers understand the harm of drug-abuse, build up self-confidence and improve EQ through interventions. It will be beneficial for the drug addicts to refrain from drug-taking and regain a normal life. Our study has proved that positive results can only be obtained from integrated intervention projects.
