Objective To investigate the treatment effect of gamma knife radiosurgery for hypothalamic hamartomas. Methods Gamma knife radiosurgery was performed in 9 patients with gelastic seizures. Collimator helmets (4 and 8 mm) were used and a radiosurgery plan was designed to cover 90% of the hamartoma at the 40%~55% isodose curve with the center dose of 28~40 Gy and the margin dose of 12~18 Gy. The clinical outcome was evaluated with the Tan’s scale. Results No complications due to gamma knife radiosurgery occurred. A follow-up from 24 to 54 months showed effectiveness in 7 patients, disappearance of seizure in 1 patient, rare occurrence in 3 patients, significantly reduced occurrence in 2 patients, improvement in seizure control in 1 patient, but ineffectiveness in 2 patients. Conclusion As an approach to the treatment of hypothalamic hamartomas, gamma knife is a safe and cost-effective therapy with rare side effects for hypothalamic harmatomas.

Objective:To investigate the criterion-related validity of Menopause-Specific Quality of Life Questionnaire (MENQOL)-Chinese version and to evaluate the effect of menopausal symptoms on health related quality of life. Methods:This study was a cross-sectional survey. Three communities were randomly chosenin Changsha,and then 340 menopausal women aged 45-55 years were randomly chosen from the documented data of the 3 community health service centers. They were required to fill out 4 questionnaires: demographic questionnaire, MENQOL-Chinese version, Kupperman Index (KI) and World Health Organization Quality of Life (WHQOL)-BREF. Correlation analysis was used to measure the criterion-related validity. Results: MENQOL-Chinese version subscales (vasomotor, psycho-social, sexual and physical) and KI total score were positively correlated (r=0.800,0.751, 0.607, 0.906 respectively); while negatively correlated with WHOQOL-BREF total score (r =-0.694,-0.851,-0.585,-0.873 respectively); MENQOL-Chinese version subscales (vasomotor, psycho-social, sexual and physical) were signiifcantly correlated with WHOQOL-BREF subscales (physical, psychological, social relationship, environment), and the physical domain was the highest among the correlation coeffcients (r=-0.915). Conclusion:MENQOL-Chinese version shows relatively high criterion-related validity compared with KI and WHOQOL-BREF, which can be widely used to measure the quality of life of menopause women in China.

Objective: To systematically evaluate the clinical effect of Xiaoke Decoction in the treatment of type 2 diabetes. Methods: Chinese databases such as CNKI, Wanfang, Weipu Chinese Biomedical Journal Database, and Chinese Medical Biological Literature Database, PubMed, Cochrane Library, Embase, and Web of Science were searched for English language literature from their inception until November 2019. A Meta-analysis was performed using RevMan 5.3 and Stata 12.0. Results: Thirty-eight studies were included in this study, with a total of 3757 patients. It was found that adding Xiaoke Decoction could improve total efficiency. The Xiaoke Decoction groups surpassed the western medicine groups regarding improvement in total efficiency (OR = 3.49; 95% CI: 2.78–4.39, P < 0.00001). Adding Xiaoke Decoction could lower the fasting plasma glucose (FPG) level. The Xiaoke Decoction groups surpassed the western medicine groups regarding reduction in FPG levels (MD = −1.14; 95% CI: −1.36 to 0.92, P < 0.00001). Adding Xiaoke Decoction could lower the 2 h postprandial blood glucose (2hPG) level. The Xiaoke Decoction groups surpassed the western medicine groups regarding reduction in 2hPG (MD = −1.40; 95% CI: −1.61 to 1.19, P < 0.00001). Adding Xiaoke Decoction could lower glycated hemoglobin (HbA1c). The Xiaoke Decoction groups surpassed the western medicine groups regarding reduction in HbA1c (MD = −0.77; 95% CI: −0.95 to 0.58, P < 0.00001). It was found that adding Xiaoke Decoction could lower the traditional Chinese medicine (TCM) syndrome score. The TCM syndrome scores among patients in the Xiaoke Decoction group were lower than those among patients in the control group after treatment (MD = −4.90; 95% CI: −7.22 to 2.57, P < 0.0001). At the same time, we conducted a subgroup and sensitivity analysis of age and intervention duration on the heterogeneity of total efficiency, FPG, 2hPG, HbAlc, and TCM syndrome score outcome indicators. For detecting publication bias, an egger test was conducted. Conclusion: Compared with western medicine alone, Xiaoke Decoction has more advantages for the treatment of type 2 diabetes with respect to total efficiency, FPG, 2hPG, HbAlc, and TCM syndrome score.

Objective To evaluate the effect of MRS-assisted stereotactic radiosurgery (SRS) for small recurrent high grade glioma (HGG).Methods A total of 54 patients with recurrent HGG were selected,the tumor diameter was less than 3 cm,the patients were divided into the conventional MRI group of 26 cases,and MRI+MRS group of 28 cases.The target region of the conventional MRI group was defined as the enhanced and short T1,long T2 area;MRI+MRS group was defined as the region of Cho/NAAindex (CNI) ≥1.6 in the surrounding short T1,long T2 and enhanced area.All the patients were followed up at least 12 months,analysed their therapeutic effect.Results Compared with the conventional MRI group,MRS+MRI group margin dose increased (19.46 Gy vs.13.58 Gy),the average diameter of target were smaller (2.6 cm vs.3.0 cm),progression-free survival was longer (6.8 months vs.5.6 months),the 1-year survival rate was higher (78.6％ vs.50.0％),and the occurrence rate of brain edema was lower (5 vs.17),the difference was statistically significant (P＜0.05).Conclusion MRI+-MRS assisted SRS helps to accurately identify the scope of HGG,its short term effect was superior.

Objective:To determine the difference of curative effects of gamma knife treatment and microsurgery on patients with recurrent trigeminal neuralgia (TN) after microvascular decompression (MVD).Methods:From January 2011 to December 2018, 65 patients with recurrent TN after MVD were enrolled in the study; 40 patients received gamma knife treatment and 25 patients received secondary microsurgical treatment. Barrow Neurological Institute (BNI) proposed pain grading was used to evaluate the efficacies right after treatment and 3 years after follow-up in all patients, and grading I-III was defined as pain relief.Results:Patients received gamma knife treatment had pain relief within 4-10 weeks of treatment and disappeared gradually; patients received secondary microsurgical treatment had disappeared facial pain immediately after waking up from anesthesia or completely alleviated facial pain within one week of treatment. Up to 3 years after surgery, follow-up results showed that 17 patients (68.0%) in the gamma knife treatment group had pain relief, and 16 patients (94.1%) in the microsurgical treatment group had pain relief; the difference in pain relief rate between the two groups was statistically significant ( χ2=4.100, P=0.043). Facial numbness was noted in the gamma knife treatment group, with an incidence of 24.0%; in the microsurgical treatment group, hemiplegia was noted in one patient and facial numbness was noted in the left ones, with complication rate of 29.4%; and the difference in complication rate between the two groups was not statistically significant ( χ2=0.010, P=0.921). Conclusion:For patients with recurrent TN after MVD, secondary microsurgical treatment and gamma knife treatment are safe and effective, among which secondary microsurgical treatment is more effective than gamma knife treatment.
