Objective To detect the safe application of autoblood re-trasfusion of medical trioxyen. Methods 50 patients who received fundamental autohemotherapy with German DR.HANSLER OZONOSAN treating system were extracted 100ml venous blood,which was mixed with 100ml,10~20?g/m1 medical trioxyen and then retransfused into the patients.We observed the adverse effect during the course of treatment and measured the blood pressure and blood glucose of every patient accordingly. Results Among the 50 cases,4 (about 8%) had adverse effect after blood extracting. 5 cases (about 10%) had adverse effect after the trioxyen re-transfusion. The cardinal symptoms included:dizziness,nausea,emesia,cold sweat,blood pressure decrease,shock etc. Conclusion Before retransfusing the medical trioxyen,handling the indications,contraindications,making the patients have good sleep and diet and have necessary comunication with them can make the negative reaction lower at most.

Hypoxic cells that exist in nasopharyngeal cancer can not be killed easily and they are the underlying cause for recurrence and metastasis. In radiotherapy for nasopharyngeal cancer, the application of Qi-benefiting and blood-supplementing Chinese medicines can improve blood circulation, increase oxygenation of tumor body, and ameliorating the status of hypoxic cells. Besides medical ozone can promote oxygen-carrying ability of hemoglobin and releasing of oxygen capacity and improve oxygen supplying. If the method of radiotherapy combined with ozone and Chinese medicines can solve the problem of resistance of hypoxic cells to radiation and promote the oxygen effect in radiation and the interaction between organisms, then it will play an important role in the treatment of nasopharyngeal cancer.

BACKGROUND: The osteoarthritis (OA) is attributed to Gubi of TCM,which is mainly caused by liver and kidney deficiency, deficiency and damage of both qi and blood and wind-cold-damp pathogen. Kidney-deficiency with coagulating-coldness syndrome is very common.OBJECTIVE: To explore the clinical effect of the treatment of OA by invigorating the kidney, dispelling the cold and activating collaterals.DESIGN: Randomized controlled clinical study.SETTING: Department of Traditional Chinese Medicine, Dongguan Shilong People's Hospital of Guangdong Province.PARTICIPANTS: Eighty-eight inpatients and outpatients who were most possible to benefit from the experiment were selected as the subjects from the Department of Rheumatism and the Clinic of Orthopedics from June 2005 to July 2006.

BACKGROUND: The repair of articular cartilage defect is always a problem that is dedicatedly solved by doctors of orthopaedics. Autologous perichondrium, periosteum or allografting of cartilage have been used previously; however, the source of the donor is limited, the fixation is difficult as well as the occurrence of endochondrial ossification and delamination between the inferior cartilage and reparative cartilage, etc. Type Ⅱ collagen, the main component of cartilage matrix, has certain effects in the repair of articular cartilage defect.OBJECTIVE: To investigate the effects of type Ⅱ collagen sponge filling on the repair of articular cartilage defect.DESIGN: A randomized controlled trial.SETTING and MATERIALS: The study was conducted in the Guangzhou Institute of Traumatic Surgery. Materials were 24 adult male purebred New Zealand Rabbits(48 knees), ordinary grade, with a body mass of (2.29 ±0. 25) kg. Animals were fed with standard feeding in separate cage.INTERVENTIONS: A full-thickness defect in articular cartilage was made on the femoral trochlear surface by a drill of 5 mm in diameter and 3 mm in depth. Rabbits were allocated into filling group(type Ⅱ collagen sponge was grafted into left keen joint defect) and control group(right knee joint defect site was set as control) according to random number table.MAIN OUTCOME MEASURES: Gross morphological and histological observation of the defect repair in each dual week within 12 weeks after operation.RESULTS: During 10 - 12 weeks, in cuntrol group: The defect area was repaired by white and soft tissue that had no resistance to press. The repaired tissue was still lower than the surrounding articular surface with clear boundary. By histological observation, it was found that the defect was repaired by the mechanism similar to inflammatory reaction and the defect is ultimately filled by the hyperplasia of hyaline degenerative fibrous tissues. In filling group: the defect was repaired by semi-transparent, smooth, textured tissues with polish that had resistance to press as well as elasticity. The repaired tissue was almost similar to the shape of the surrounding cartilage,difficult to be distinguished. After histological observation, it was found that there was no inflammatory reaction, but active hyperplasia of inner bonetissue and cartilage tissues; a lot of osteoid tissues and trabeculation were found. Newlborn cartilage was fused with surrounding cartilage tissue and connected with surrounding tissues. Type Ⅱ collagen had significantly promoting effects in the repair of articular cartilage defect, and the repaired cartilage was close to normal cartilage. CONCLUSION: The self-made high purity type Ⅱ collagen sponge has favorable promoting effects in the repair of articular cartilage defect with good histocompatibility but without obvious toxic side effect.

Objective To evaluate the efficacy of stereotactic body radiation therapy (SBRT) for hepatic metastases from colorectal cancer,and to collect data for the application of this technique.Methods A total of 28 patients from No.306 Hospital of PLA,including 17 male and 11 female with median age of 63.8 (range from 31 to 86),were treated with SBRT for colorectal cancer with liver metastases with 54 lesions in total.The GTV,CTV and PTV were delineated above the enhanced CT scans acquired during normal quiet respiration.CTV was obtained by adding 5 mm isotropic margin from GTV,and PTV was obtained by adding 5 to 10 mm isotropic margin from CTV.Prescription dose line covered 50％-60％ of isodose curve at 3-6 Gy/fraction.The total dose was 39-45 Gy and the biologically equivalent doses(BED)was 50.7-65.3 Gy.The patients were followed-up beginning at 3 months after SBRT.The change in size of the lesion based on enhanced CT or MR scans was evaluated.Toxicity was evaluated and scored according to the RTOG criteria.Local control rate and survival rate were analysed.Results All patients completed the treatment.With median follow-up of 15.1 months (range frome 3 to 30 months),7 patients survived at the end of follow-up.The local control rate (LC) was 79.2％,and 1-and 2-year overall survival rate(OS) were 82.7％ and 48.6％,respectively.There was a close corelation between the size of lesion and the LC.The LC (PR + CR) was much better at the size of lesion less than 14 cm3 than that at the size more than 65 cm3(x2 =4.17,P＜0.05).When the size was more than 180 cm3,the LC was zero.Toxicity included fatigue (60.7％),grade 1 and 2 digestive system toxicity (28.6％),a transient grade 1 and 2 bone marrow suppression (46.4％) and a transient increase in transaminase(17.8％).No grade 3 toxicity and above and late toxicity were observed.Conclusions Stereotactic body radiation therapy could be suggested as the first choice for the selected patients who suffer form colorectal liver metastases,especially for those who cannot undergo surgery.

Objective To compare the influence of hemodialysis (HD) and peritoneal dialysis (PD) on early outcome of patients underwent kidney transplantation from donation after cardiac death (DCD).Methods Patients admitted in the First People's Hospital of Foshan with DCD kidney transplant from January 1st,2011 to June 30th,2016 were analyzed retrospectively.Recipients were grouped into HD group (n=61) and PD group (n=28) according to their pre-transplant dialysis modality.Their short-term outcomes after DCD kidney transplant were compared,including recovery of renal function,short-term complications and laboratory data.Results Patients had longer dialysis duration and lower hemoglobin,serum albumin and phosphorus in PD group than those in HD group (all P ＜ 0.05),but no significant difference shown in age,gender,body mass index,primary disease,blood pressure,and hepatitis B infection (all P ＞ 0.05).HD patients with 6.00(4.00,11.00) d recovery time of renal function,18.00(17.00,21.50) d hospital time,had 24.59％ the delayed graft function (DGF),3.28％ acute rejection and 16.39％ infection during hospitalization.While for PD patients the recovery time of renal function was 4.00(3.75,7.00) d;hospital time was 19.00(15.00,21.75) d;the incidence rate of DGF was 14.29％;acute rejection was 3.57％;and infection during hospitalization reached 17.86％.Above indexes were not significantly different between HD and PD groups (all P ＞0.05).Repeated measure ments showed that,compared with those before transplant surgery,after 1 month,3 months and 6 months HD and PD groups had decreased creatinine and phosphorus,and increased hemoglobinserum albumin and calcium;Serum albumin and calcium were different between the two groups (P ＜ 0.001,P=0.040),whereas creatinine,hemoglobin and phosphorus did not show difference (all P ＜ 0.05).After transplantation the trends of creatinine,hemoglobin,calcium and phosphorus were not different between the two groups (P values were 0.295,0.310,0.501 and 0.063,respectively).Conclusions No significant difference of the recovery regarding renal function,anemia,nutrition status and mineral metabolites was found between pre-transplant HD and PD modality in patients who underwent DCD kidney transplantations.

Objective To analyze the efficacy and prognosis of stereotactic radiotherapy (SRT) and whole-brain radiotherapy (WBRT) in treatment of brain metastases,and to observe the influence of temozolomide (TMZ) on survival rate during the period of radiotherapy.Methods A total of 52 patients with brain metastases were divided into two groups according to treatment methods,including 35 patients treated with WBRT plus SRT and 17 patients treated with SRT alone.WBRT dose was 1.8 - 3.0 Gy per fraction,one fraction a day,five fractions per week,with total dose of 30 - 40 Gy.After WBRT,gamma knife was performed with prescription isodose line of 45％ -70％ surrounding the planned target volume in WBRT + SRT group.The marginal dose was 12 - 15 Gy and the center dose was 20-30 Gy.In SRT group,the prescription isodosc line was 45％ - 70％ and the marginal dose was 36 - 40 Gy while the center up to 70 - 80 Gy.The follow up time was 1 - 2 years.Besides 20 patients in this study took temozolomide capsule during and after radiotherapy.The schedule of concomitant chemotherapy was temozolomide of 75 mg/m2 by oral administration every day until radiotherapy was over,and then temozolomide of 150 mg/m2 was taken for 3 -6 months after radiotherapy.Results The efficiency during 1 -3 months after treatment was 84.62％ in this study.In the WBRT + SRT group,the efficiency was 88.57％ and declined to 76.47％ in the SRT group.The six month-and one year-local control rate were 92.10％ and 85.20％,respectively.The average survival time of WBRT + SRT was 13.2 months and median survival time was 11 months.Six month-,one year-and eighteen months-survival rate were 71.40％,54.30％ and 14.30％,respectively.In the SRT group,the average survival time was 10.2 months and median survival time was 9 months.Six month-,one year- and eighteen month-survival rate were 41.20％,23.50％ and 5.88％,respectively,while those for RT + TMZ group were 80.00％,60.00％ and 10.00％.In comparison,those in RT group were 56.30％,37.50％ and 12.50％,respectively.Conclusions Effect of gamma knife stereotactic radiotherapy combined with WBRT is better than GK stereotactic radiotherapy alone in treatment of brain metastases.Compared with radiotherapy alone,concomitant temozolomide chemotherapy could improve the survival rate of the patients with brain metastases without increasirg adverse reactions significantly.

BACKGROUND: Fibronectin(FN) plays the role of repair in the inflammation. There is no confirmed conclusion whether it can be applied to the refractory corneal epithelial defect.OBJECTIVE: To observe the repair effect of the human plasma FN for the refractory corneal epithelial defect.DESIGN: A controlled experimental study.SETTING: Guangzhou Red Cross Hospital, Guangzhou First People's Hospital, Guangzhou Children's Hospital, Guangzhou Hospital of Traditional Chinese Medicine and Guangzhou Second People's Hos pital.PARTICIPANTS: Totally 383 eyes with the refractory corneal epithelial defect were chosen, of which 309 were in the therapy group, and 74 in the control group.METHODS: The therapy group: Human plasma FN was administered by dropping it into the eyes once every two hours. The controlgroup: 10 g/L celacol M was administered by its dribbling into the eyes once every two hours. Weilesheng was taken orally in both groups, two pills once, three times per day. According to the state of illness, both groups received anti-bacterial or anti-viral treatment and reexamination was given every day or every other day after administration. 10 g/L fluorescein sodium was used to observe the changes of cornea.MAIN OUTCOSE MEASURES: The symptoms, results of staining using fluorescein sodium as well as the corneal epithelial healing of both groups.RESULTS: The symptoms, the results from staining using the fluorescein sodium and the corneal epithelial healing were used for the evaluation. In the therapy group, 309 eyes were followed up and the cure rate was 69.9%. The average therapeutic period was 6.5 days, while those of the control group were 58.1% and 8.7 days respectively. The difference in the curative effect between the two groups was significantly different( P＜0.01 ).CONCLUSION: The application of FN for the refractory corneal epithelial defect displays a more significant effect than conventional treatment.

Objective To evaluate the therapeutic efficacy of stereotactic body radiotherapy (SBRT) with gamma knife on stage Ⅰ-Ⅱ non-small-cell lung cancer(NSCLC)and the quality of life of the patients undergoing this therapy.Methods Twenty NSCLC patients with the median age of 76,10 at stage Ⅰ and 10 at stage Ⅱ who were unable or unwilling to undergo surgery were given SBRT with gamma knife at the doses of 3-6 Gy in 8-15 fractions,finished within 2 to 3 weeks.The prescription isodose line was 50％,the marginal dose was 39-56 Gy,the central dose was 78-112 Gy,and the total biologically effective dose was 51-83 Gy.The patients were observed after admission and followed up by chest CT 1,3,6,and 12 months after treatment until progressive disease or death.EORTC QLQ-LC43 questionnaire was used to investigate the changes in quality of life.Results The 20 patients were followed up for 24 (12-46) months.At six months after the treatment,the overall response rate was 80％,and the complete response rate was 35％.The 1,2 and 3-year local control rates were 100％,95％ and 95％,respectively.The 1,2 and 3-year overall survival rates were 95％,80％ and 50％ respectively; The 1,2,and 3-year progression free survival rates were 85％,64％ and 33％,respectively.The failure rate was 20％ and the rate of progress within the planning target volume was 5％.No acute toxicity at grade 3 and over occurred in any patient during the treatment.15％ of the patients developed grade 1-2 radiation pneumonia.Age,gender,pathologic index or not were weakly correlated with the overall survival.The emotional function was improved significantly after treatment (P ＜ 0.05),dyspnea and cough were improved at different degrees,however,not significantly.There were no significant changes in the physical function and symptoms,such as fatigue,lack of appetite,insomnia,etc.Conclusions Significantly improving the motional function and maintaining the quality of life,SBRT with gamma knife is effective for elderly NSCLC patients with high local control rate fair overall survival rate and few side effects.
