Objective To investigate the feasibility and effectiveness of inducing cerebral vasuspasm by injecting autologous blood into cisterna magna (CM) twice after puncture of CM with a fine needle in dogs.Methods Six healthy aduh mongrel dogs of both sexes weighing 14-18 kg were involved in this study. The animals were anesthetized with intraperituneal 3% pentobarbital sodium 30-40 mg/kg. Spontaneous breathing was kept. Nonheparinized autologous arterial blood 0.5 ml/kg was injected into CM twice at the rate of 0.5 ml/s at 48 h interval after puncture of CM with a fine needle. Neurological function was assessed and scored ( 1 = normal, 5 =dead) and CT angiography was performed to determine the diameter of cerebral basilar artery before the first CM injection (T1 , baseline) and at days 7, 14 and 21 after the second CM injection (T2.4 ). Results The injection of autologous blood into CM twice significantly increased the success rate of the puncture and intraoporative survival rote of the animal*. The neurological function scores were significantly increased and diameter of cerebral basilar artery shortened at T2 and T3 compared with the baseline value. Conclusion The model of cerebral vasospasm after subarachnoid hemorrhage can be successfully established by injecting autologous blood into CM twice following puncture of CM with a fine needle in dogs, with higher postoperative survival rate and less injury to the animals.

Objective To investigate the effect of music electroacupuncture on perifocal ferric ions and neuronal apoptosis and the brain water content in rats with acute cerebral hemorrhage and explore the mechanism of its action on acute cerebral hemorrhage.Methods One hundred and twenty-eight healthy adult male Wister rats were randomized to normal, model, electroacupuncture and music electroacupuncture groups. In each group, four time points of 6 hrs, 24 hrs, 3 days and 7 days were set up, eight rats each time point. A rat model of acute cerebral hemorrhage was made using collagenase. In the electroacupuncture and music electroacupuncture groups, point Baihui was connected to the anode and point Taiyang to the cathode, 2 voltage was used as a selection parameter and electroacupuncture lasted 30 min. Intracerebral perifocal ferric ions and neuronal apoptosis and the brain water content were measured at four time points of 6 hrs, 24 hrs, 3 days and 7 days after model making.Results Intracerebral ferric ion content was higher in the model, electroacupuncture and music electroacupuncture groups of rats than in the normal group at 6 hrsafter model making (P<0.05), lower in the electroacupuncture and music electroacupuncture groups than in the model group at 24 hrs, 3 and 7 days after model making (P<0.05) and lower in the music electroacupuncture group than in the electroacupuncture group at 3 and 7 days after model making (P<0.05). Intracerebral neuronal apoptosis was higher in the model, electroacupuncture and music electroacupuncture groups of rats than in the normal group at 6 hrs after model making (P<0.05) and lower in the music electroacupuncture group than in the electro- acupuncture group at 7 days after model making (P<0.05). The brain water content was higher in the model, electro- cupuncture and music electroacupuncture groups of rats than in the normal group at 6 and 24 hrs after model making (P<0.05), lower in the electroacupuncture and music electroacupuncture groups than in the model group at 3 days after model making (P<0.05) and lower in the music electroacupuncture group than in the electroacupuncture group at 7 days after model making (P<0.05).Conclusions Music electroacupuncture has a benign regulating effect on intracerebral perifocal ferric ions, inhibits neuronal apoptosis around hematoma in the early stage and reduces cerebral edema in rats with acute cerebral hemorrhage. Its therapeutic effect is superior to that of electroacupuncture.

Objective To reduce unreasonable use of antibiotics in acute suppurative tonsillitis cases. Methods Retrospective analyses of 1107 acute suppurative tonsillitis cases from the pediatric outpatient department were conducted.According to course of antibiotic treatment, these cases were divided into the group of full course of treatment and the group of insufficient course of treatment.According to the types of antibiotic, the subjects were di-vided into azithromycin group and non-azithromycin group.Three months after the onset of illness, the occurrence of complications and illness relapse between full course of treatment group and insufficient course group, azithromycin group and non-azithromycin group were analyzed.Meanwhile, the cases were divided into Chinese mainland group, Macao and Taiwan group, and foreign group according to their native places and nationalities.We compared the num-ber of cases used insufficient course in these three groups and analyzed their reasons.Results The relapse rate was significantly lower in the full course treatment group compared with insufficient course treatment group ( P<0.05 ) , and significantly higher in non-azithromycin group compared with azithromycin group ( P<0.05 ) .The occurrence rate of insufficient course treatment in the Chinese mainland group was obviously higher than the Macao group, Tai-wan group and foreign group (P<0.05).The main reasons for insufficient course of treatment were the insufficient patients′obedience and some doctors′poor understanding of the disease course.Conclusion A full course treatment with antibiotics on acute suppurative tonsillitis are strongly suggested.It may be of great significant to strengthen the awareness of reasonable use of antibiotics among the inland citizens.

Objective To investigate the clinical value and relating problems in treating complex fractures of proximal humerus by using replacement of humeral head prosthesis. Methods There were 23 cases (10 males and 13 females, age range 43-76 years, mean 58.6 years) with complex fractures of proximal humerus. According to Neer classification, 4 cases had three-part fracture, 17 four-part fracture, 2 cleavage fracture of humeral head, 18 fresh fracture (within 2 weeks after injury) and 5 old fracture, which were all treated with replacement of humeral head prosthesis. Results Follow-up study for a mean period of 15.6 months was conducted in all the cases. No flexible prosthesis, prosthesis dislocation, infection, nerve damage or periprosthesis fractures occurred. According to scoring system modification for hemiarthroplasty (SSMH) of UCLA (Los.Angeles, California, USA), the average score was 26.3. Score was above 27 (excellent) in 3 cases and 24-27 (good) in 18 with an excellence rate of 91.3%, score was 18-24 (moderate) in 2 but no one had score less than 18. Average score was 9.5 in pain, 8.6 in function and 8.2 in muscle power and motion in 23 cases. Conclusions Replacement of humeral head prosthesis is a preferable method for treating the complex fractures of proximal humerus, with significant effect in relieving the pain in the shoulder joint posterior to trauma. It is key to a satisfactory curative effect to correctly select the indication, clearly master the local anatomy, grasp the operation technique and give early and reasonable postoperative rehabilitation treatment.

Objectives In order to evaluate the clinical effect of manipulation combined with traditional Chinese medicine for the lateral epicondylitis.Methods A total of 150 patients with lateral epicondylitis were randomly divided into two groups, 75 patients in each group.

The PRI score after treatment (19.5 ± 8.0vs. 22.3 ± 5.7,t=-3.574), one month after treatment (13.7 ± 4.7vs. 17.3 ± 5.3,t=-3.985), and three months after treatment (9.3 ± 6.6vs. 12.5 ± 4.8,t=-1.270) in the treatment group were significantly lower than those in the control group (P<0.05).Conclusions The Manipulation combined with traditional Chinese medicine bathing therapy can relief the symptoms of lateral epicondylitis, and improve the clinical curative effect.

Background Laser assisted in situ keratomileusis (LASIK) for myopia will change corneal asphericity and further affect the quality of vision.However,how operating parameters such as ablation depth and optic zone diameter affect corneal asphericity is still rarely reported.Objective Aim of this study was to investigate the influence of corneal ablation depth and optic zone diameter on corneal asphericity after LASIK for myopia.Methods This prospective study comprised 175 eyes of 89 patients with the spherical equivalent of (-5.93± 1.98)D and the best corrected visual acuity (BCVA) ≥ 1.0.The flap creation with the femtosecond laser combine iris recognize guided LASIK was performed on the patients who were available for the evaluation at postoperative 6 months.Corneal aspherical index (Q value) at the central corneal 6.0 mm were measured with Orbscan IIz-corneal topography before and 6 months after operation.Corneal ablation depth and optic zone diameter were recorded in operation.The changes of visual acuity and spherical equivalent before and after surgery were compared by self-control method,and the correlations between corneal ablation depth or optic zone diameter with alteration of Q value (AQ) after LASIK were assessed using multiple regression analysis.Results The mean spherical power,cylinder diopter and spherical equivalent were (-5.57 ± 1.89) D,(-0.71 ±0.55) D and (-5.93 ± 1.98) D before surgery,and those after surgery were (-0.25 ±0.30),(-0.14±0.22)D and (-0.32±0.37)D,showing significant differences between before and 6 months after LASIK (t=-32.39,-23.91,-35.18,all at P＜0.01).The Q values at the central corneal 6.0 mm were -0.13 ± 0.09 (-0.47-0.08) in preoperation and 1.09 ± 0.54 (0.22-2.51) in postoperation,with a significant increase in postoperation (t=29.37,P＜0.01).Corneal ablation depth was (95±28) μm and optic zone diameter was (6.32±0.26)mm.Ablation depth appeared to be positive correlation with AQ (β =0.803),and optic zone diameter showed a negative correlation with AQ (β =-0.149),with a multiple regression formula AQ =1.517+0.015×ablation depth-0.3 ×optic zone diameter.Conclusions LASIK for myopia increase corneal Q value.The increase of corneal ablation depth and decrease of optic zone diameter contribute to enlargement of corneal Q value.

Objective To investigate the clinical value of dual phase 18F-FDG PET/CT in the diagnosis of recurrent and metastatic bladder cancer after surgery. Methods The imaging data from 84 patients underwent the dual phase 18F-FDG PET/CT after surgery with known histories of bladder cancer were analyzed. Among the 84 patients, 16 had symptoms of recurrence, 24 had symptoms of metastasis and 44 didn′t have any symptom. The median interval time between the primary tumor resection and the PET/CT scan was 11.5 months (0.5 ~ 240 months). According to the PET/CT imaging procedures, all patients underwent whole body PET/CT scan at 60 minutes after IV injection of 18F-FDG. Additional delayed pelvic PET/CT images were acquired after forced diuresis by using oral 40 mg furosemide. The 18F-FDG PET/CT findings were compared with histopathologic examination results and (or) the clinical follow-up. All patients were followed up for more than six months. Results Results of detecting recurrence and metastasis of bladder cancer showed that the sensitivity, specificity, accuracy, positive predictive value and negative predictive value of the dual phase FDG PET/CT imaging protocol were 91.7%(22/24), 95.0%(57/60), 94.0%(79/84), 88.0%(22/25), 96.6%(57/59) and 90.0%(27/30), 96.3%(52/54), 94.0%(79/84), 93.1%(27/29), 94.5%(52/55), respectively. Conclusion Dual phase FDG PET/CT can be used to detect the recurrence and metastasis with high accuracy, contributing to the restaging and follow-up in bladder cancer after surgery.

A 7?year?old girl presented with a plaque on the left side of the face for 4 years. Skin examination revealed a well?marginated circular firm plaque measuring 6 cm × 5 cm in size on the left side of the face with purulent crusts on the surface, which was nontender to palpation. Histopathologic study showed ulceration and necrosis in some areas in the epidermis, diffuse dermal infiltration of lymphocytes, histiocytes and epithelioid cells with the presence of many neutrophilic granulocytes in some regions. Both periodic acid?Schiff(PAS)staining and acid?fast staining were negative. After 25 days of tissue culture, scotochromogenic Mycobacterium colonies grew, and colony smears showed positive acid?fast staining. The sequences of 16S rRNA and hsp65 genes of the fungal isolate showed 100%and 99%homology with those of Mycobacterium szulgai, respectively. After the treatment with rifampicin, isoniazid and ethambutol, the patient′s condition was improved.
