BACKGROUND: Trigeminal ganglion percutaneous puncture is one of the methods for the therapy of primary trigeminal neuralgia. The difficulties in percutaneous puncture technique and operation can lead accidental injury and some serious complications. The application of DZY-C trigeminal nerve stereoguide in the treatment of trigeminal neuralgia has the features of high accuracy in puncture and low complications, which can reduce the chances of accidental injury to surrounding vessels and nerves.OBJECTIVE: To evaluate the therapeutic effects of DZY-C trigeminal nerve stereoguide in the treatment of trigeminal neuralgia.DESIGN: A before-and-after experimental study based on patients.SETTING: Department of cerebral surgery of a municipal hospital of tradi tional Chinese medicine and a municipal hospital.PARTICIPANTS: Ninety patients including 39 male and 51 female patients with primary trigeminal neuralgia aged between 21 and 90 years old were selected from outpatient or inpatient department of Foshan Hospital of Traditional Chinese Medicine between 2001 and 2003.INTERVENTIONS: Glycerine was injected into trigerminal ganglion of each patient through percutaneous puncture under the guidance of DZY-C trigeminal nerve stereoguide. Therapeutic effects were evaluated by visual analogue scale(VAS) before and 30 minutes after the treatment.MAIN OUTCOME MEASURES: Results of therapeutic effects.RESULTS: Ninety patients with primary trigeminal neuralgia received trigeminal ganglion puncture with the application of DZY-C trigeminal nerve stereoguide. All punctures succeeded with one shot. After the injection of glycerine, the original trigeminal neuralgia disappeared in all 90 cases with the good and excellent rate of 100%.CONCLUSION: Trigeminal nerve stereoguide(DZY-C model) has the features of reasonable structural design, easy surgical operation, agile adjustment, less tissue injury, and safe manipulation, which can significantly eliminate trigeminal neuralgia.

Objective To explore the pharmacological action of Bazheng mixture(BM) on infections disease of urinary system and effects of BM on immune function in mice.Methods After E.coli was injected into bladder of mice, the kidneys were examined for the anti-infection action of BM on ascending infection;and the effects of BM on immune function of mice were tested.Results BM ig remarkably decreased the percentage of kedney's infections area caused by ascending infection of E.coli [ED_(50) was(11.01?1.63)g/kg and the 95% CL was (9.50-12.76)(g/kg]);BM was also found effective in increasing the rate of carbon particle clearance and the index of carbon particle clearance,but BM had no significant effects on body fluid immunity and cell immunity in test for mice.Conclusion The mechanism of BM in treating infections disease of urinary system are mainly associated with the increasing rate of carbon particle clearance,and with bacteria clearance in urinary system.

Purpose To investigate the application value of 18F-FDG PET/CT in the diagnosis and staging of tongue cancer,in order to improve the accuracy of preoperative staging.Materials and Methods The 18F-FDG PET/CT findings of 52 patients with pathologically confirmed tongue cancer were retrospectively analyzed.The tumor location,size,FDG metabolic characteristics and tumor staging were observed,and compared with postoperative pathology.Results PET/CT showed that most patients were at middle or late stage when initially diagnosed (28/52).The lesions were mostly located on middle or middle-back region of tongues,and the average SUVmax was 6.81 ± 3.81.The sensitivity of PET/CT diagnosing tongue cancer was 94.2％.There was no significant difference in SUVmax between high,medium-high and medium differentiated tongue cancer primary lesions (P＞0.05).The SUVmax of tongue cancer at stage Ⅲ and Ⅳ was obviously higher than that at stage Ⅰ and Ⅱ,and the difference was statistically significant (P＜0.008).The diagnose and staging of tongue cancer using preoperative PET/CT and postoperative pathology were in excellent consistence (Kappa=0.859,P＜0.01).The staging accuracy reached 90.4％ (47/52).Conclusion Higher SUVmax value indicates worse tongue cancer staging,but it is of little significance in predicting differentiation.PET/CT can provide an objective imaging basis for preoperative diagnosis and accurate staging of tongue cancer.

Objective:To investigate the construction and application of telemedicine system in Tibet Autonomous Region.Methods:From June to July 2020, medical institutions at all levels in Tibet Autonomous Region were visited. Relevant information was collected through discussion, questionnaires and field visits, and the data of effective questionnaires were statistically analyzed.Results:A total of 125 medical institutions were visited, covering 7 regions of Tibet Autonomous Region, of which 74 medical institutions were able to realize audio-video two-way communication with the telemedicine platform of the PLA General Hospital. Seventy-three valid questionnaires were collected, and 64(88%)hospitals had software or hardware audio and video terminals. Twenty-five hospitals had never carried out remote consultation, accounting for 34%. The annual remote consultation amount of 35 hospitals was less than 10 cases, and that of 11 hospitals was 11-100 cases. Only 2 hospitals had carried out remote ECG and remote ultrasound diagnosis, with an annual consultation volume of more than 100 cases.Conclusions:The hospitals at or above the county level in Tibet Autonomous Region have established telemedicine system, but there are few remote services, the system idle rate is high, and the distance education resources are not matched.
