Objective To observe the influence of cervical traction and manipulation on hemorheology of cervical vertigo patients.Methods 59 patients in outpatients of our hospital from January 2012 to August 2013 were recruited and divided into a control group(29 patients)and a treatment group(30 patients)randomly. The control group was treated with flunarizine, and the treatment group was additionally treated with cervical traction and manipulation on the basis of the control group. After 4 therapeutic causes, evaluation of cervical vertigo symptoms and functions(ESOV)were performed and hemorheological changes were observed in both groups.Results① ESOV comparison: ESOV sores in both groupswere obviously improved after the treatment than the same group before the treatment(t=11.028, 5.825,all P<0.01)the treatment group were significantly lower than that in the control group after treatment(t=3.6057,P<0.01).② hemorheology changes comparison: whole blood viscosity(high-, medium- , low shear), whole blood reduction viscosity, erythrocyte aggregation index, hematocrit in the treatment group were improved obviously after the treatment than before(t=3.356, 13.245, 3.650, 7.443, 9.912, 3.113,P<0.05 orP<0.01). The whole blood viscosity(high-, medium-shea), blood reduction viscosity, erythrocyte aggregation index in the control group were obviously improved than the before(t=2.144, 4.216, 3.287, 3.039, 6.442,P<0.05 orP<0.01). The difference between the two groups were also obvious after the treatment(P<0.05 orP<0.01).Conclusions Cervical traction and manipulation combined with flunarizine can elevate ESOV score, improve hemorheology and therapeutic effect in patients with cervical vertigo.

Objective To study the method and effect of the combination treatment based on the minimally invasive surgery and radioactive seeds brachytherapy for lung cancer. Methods Entered the study there were 12 cases of lung cancer (4 cases of primary lung cancer, 3 cases of recurrent lung cancer, and 5 cases of metastatic lung cancer) between November 2001 and February 2002. All the 12 patients received thoracoscopic mini operations, including 5 cases of local wedge-shaped tumor resection combined with seeds implantation, 3 cases of radio frequency thermaerotherapy combined with seeds implantation, 3 cases of percutaneous radio frequency with seeds implantation, and 1 case of seeds implantation only. Postoperative combination treatment was conducted in accordance with the patient's general condition. Results All the patients were followed for (12～30) months. The local control rate in the study was 83%, and the survival time was more than 1 year. Two patients expired in the 18th and 21st postoperative months, respectively. No decreases of the white blood cell and platelet took place. Conclusions The combination treatment based on minimally invasive surgery and radioactive seeds brachytherapy provides high local control rate, high life quality and satisfactory survival time.

Objective To investigate three-dimensional dose distribution for 103Pd radioactive stent.Methods The surface dose,the axial dose and radial dose in surface for 103pd stent (3 mm × 13 mm) were estimated by experimental simulating method, analytic function and MCNP4b code. Three-dimensional dose distribution was calculated by MCNP4b code. Results The surface dose of 103pd stent was 0. 109 and 0. 106 Gy estimated by experimental simulating method and MCNP4b code,between which the difference was less than 3%. The axial dose calculated by analytic function and MCNP4b code was well consistent,and so was the radial dose estimated by the three methods. Dose rate table were estimated by MCNP4b code. Conclnsions Dose distribution for 103 Pd stent estimated by the three methods is relatively accurate. Three-dimensional dose table estimated by MCNP4b may be used to calculate dose for 103Pd stent in animal experiment and clinical application.

OBJECTIVE: To study the effects of Cordyceps sinensis on dimethylnitrosamine-induced liver fibrosis in rats. METHODS: SD rats were divided into normal control group, untreated group and Cordyceps sinensis-treated group. The rats in each group were fed with corresponding drug for 4 weeks. The rat's liver collagen deposition was observed with collagen staining. Hydroxyproline (Hyp) contents in liver tissue of the rats in 3 groups were determined with HCl hydrolysis. The tissue inhibitor of metalloproteinase-2 (TIMP-2) and type IV collagen contents were observed by Envision, and matrix metalloproteinases-2 (MMP-2) activity was detected by the method of enzyme-picture. Type I collagen was detected by Western blotting. RESULTS: The contents of Hyp, TIMP-2, type IV collagen, and the expression of type I collagen in untreated group were significantly higher than those in the normal control group, while those in Cordyceps sinensis-treated group were significantly lower than those in the untreated group. The content of MMP-2 in untreated group was significantly lower than that in the normal control group, while that in Cordyceps sinensis-treated group was significantly higher than that in the untreated group. CONCLUSION: Cordyceps sinensis can considerably relieve the liver fibrosis, and the mechanism may be related to promoting the degradation of the collagens.

This is a retrospective study of 103 cases of early gastric cancer undergoing surgery during the years of 1974-1988 with a special discussion on surgical treatment.The lesions were localized to the mu-cosal layer in 54.3%,to submucosal layer in 45.7%,In 10% of patients there was lymphnode metastasis,all of them were in the first station.Operation consisted of radical subtotal gastrectomy in 94.2%.and total gastrectomy in 5.8%.The extent of lymphatic excision was:Ro in 12.6%,R1 in 61.2% and R2 in 26.2% Postoperative chemotherapy was given in 61.2%.However no statistical difference of 5 years survival rate was found in respect to the extent of lymphatic excision as well as postoperative chemotherapy.Since 60.2% of EGC lesions were of minute,multiple and plane type,preoperattve en-doscopy and intraoperative biopsy of gastric mucosa,if necessary,should be carefully done to ascertain that no lesion was overlooked in the remnant of the stomach.Follow-up rate was 96%,and the survival rates of 3 and 5 years were 97% and 93.7%.This makes the authors believe that a radical operation of R1 is justified and routine postoperative chemotherapy is unnecessary.

In this communication, the values of serum CA-50 in a series of patients with benign and malignant GI diseases are reported. It was found that CA-50 was positive in 86.7% of 30 pancreatic cancer patients with an average level of 427.53U/ml, which was statistically different from that found in non-malignant control group. In this series serum CA-50 determination helped to confirm the diagnosis of pancreatic cancer in 6 cases, in which B-mode ultrasono-graphy failed to make a definite diagnosis, and in another 3 cases CT scanning was unable to disclose the tumor. The combination of CA-50, B-mode ultrasonography, and CT made definite diagnosis in 100% of all 30 pancreatic cancer patients. The author discussed the significance of CA-50 determination in the diagnosis and differential diagnosis of pancreatic cancer.

Objective To investigate the imaging features of the calvarial cavernous hemangioma and the surgical efficacy to improve diagnosis and treatment of the calvarial cavernous hemangioma.Methods The clinical information,imaging materials and surgical efficacy from ten cases of calvarial cavernous hemangioma confirmed by pathology and the related literature was reviewed.Results The lesion was located in frontal bone in eight cases,in parietal bone in one case and in occipital bone in one case.The lesions were round-shape hypodensity with clear margin in X-ray.The lesions were hyperdensity or slightly hyperdensity on CT scan,and were osteolytic lesions with a characteristic honeycomb or starburst pattern on bone window.The MRI features were complicated and variable.The lesions were heterogenous and unevenly enhanced signal intensity.Nine patients underwent radical resections and reconstructed immediately by titanium mesh.The patient with tumor in occipital bone underwent radical resection only.Macroscopically,the pathologic bone was a huge purple-red blush mass protruding from the skull surface.Histological examination revealed the diploe with large,thin-walled,dilated blood-filled spaces lined by flattened endothelial cells without evidence of malignancy.No recurrence was noted in any case during a follow-up period from 3 to 24 months.All the patients survived well without recurrence.Conclusions The imaging features of calvarial cavernous hemangioma have a high value in the diagnosis and may provide guidance for the treatment.The radical resection and immediate reconstruction treatment for calvarial cavernous hemangioma is satisfied.

Objective　To investigate the clinical feasibility of robotic-assisted laparoscopic radical cystectomy (RARC) by da Vinci surgical system and to summarize the operative technique and outcomes.Methods　From December 2007 to March 2012,22 patients (20 males and 2 females) with the bladder urothelial carcinomas were enrolled.Patient age was from 37 -72 years (rnean 62 years) ; the body mass index was 22.5 - 30.1 kg/m2 ( mean 26.1 kg/m2 ) ; and the American Society of Anesthesiologists score was 1 -2. All patients were diagnosed preoperatively with muscle -invasive or high-risk non-muscle-invasive bladder urothelial carcinomas in cystoscopic biopsy.There were no adjacent organ infiltration,pelvic lymph node involvement or dístant metastasis found on preoperative examinations.The clinical stage of all cases was under T2 N0 M0.Patients were under general anesthesia for RARC with urinary diversion.Extracorporeal urinary diversions (orthotopic ileal neobladder for 2 patients and ileal conduit urinary diversion for 13 patients)were performed on 15 patients and intracorporeal urinary diversions ( ileal conduit urinary diversion for 2 patientsand orthotopic ileal neobladder for 5 patients) were performed on 7 patients.　Results　All RARC procedure were completed on patients as planned.The operative time was 300 - 667 min ( mean 480 min)with estimated blood loss of 100 - 1200 ml (mean 550 ml),and the number of removed lymph nodes was 6 -25 (mean 15). All patients resumed ambulation on the 2nd to 3rd day postoperatively,and bowel function recovered on the 3rd or 4th day postoperatively.The length of hospital stay was 8 - 35 days ( mean 16 days).For patients underwent orthotopic ileal neobladder,the ileoureteral stents and the urethral catheter were removed 1 month after a cystogram confirming watertight healing.During the follow up of 4 -49 months (mean 32 months),2 patients had disease recurrence and 1 patient died of disease development and 2 patients had developed hydronephrosis.The other patients were with good urinary continence and normal renal functions.　Conclusions　RARC with urinary diversion are feasible and safe treatment option for bladder urothelial carcinoma.This technique will be more popular with more extensive surgical experiences and large randomized clinical trials.
