Objective To observe the short-term and long-term effect of microvascular decompression in patients with trigeminal neuralgia (TN).Methods The chnical data of 180 patients with TN treated with microvascular decompression were retrospectively analyzed.The pain improvement of patients in 2 years was observed,combined with age and course of disease,as well as the type of pressure vessels,whether obvious impression and so on,to analysis the recurrence factors of TN.Results All patients were found with vascular compression,including 93 cases with apparent pressure pressing mark,85 cases with arterial compression,15 cases with venous compression,and 8 cases with arteriovenous compression,among of them 74 patients with artery compression had pressure pressing mark,and 11 patients with vascular compression had pressure pressing mark,all of 8 patients with arteriovenous compression had pressure pressing mark.One week postoperatively,the patients with vascular compression gained significant improvement,of which 79 cases achieved optimal,6 cases achieved good;9 patients with vascular compression achieved optimal,6 cases achieved good,and 5 patients with arteriovenous compression achieved optimal,3 cases achieved good.Follow-up for 1 year after surgery,artery compression recurred in 5 cases,of which 3 cases of part recurrence,2 cases of recurrence completely ;vascular compression recurred in 6 cases;arteriovenous compression recurred in 2 cases.Univariate analysis showed that the vascular compression type,bascular compression notch and duration were the risk factors of postoperative recurrence (P ＜ 0.01).Multiple analysis showed that the vascular compression type,bascular compression degree and duration were the independent risk factors of postoperative recurrence (P ＜ 0.05).Conclusions TN patients treatd with microvascular decompression have effective improvement.History of diease,vascular compression type and compression degree are the important influence factors of postoperative recurrence.

Objective To investigate the protective effect of protocatechuic acid(PCA)on the PC12 cell model of Alzheimer’s disease(AD)and to explore its mechanism . Methods Amyloid beta peptide 1-42(Aβ1-42)fiber polymers were identified by immunofluorescence. After PC12 cells were stimulated with the Aβ1-42 fiber polymers, the cellular morphology was observed at different time points of hour 0, 3, 6, 9, 12, 24 , and the cellular viability was tested by methyl thiazolyl tetrazolium(MTT)assay to monitor the modeling condition. The effect of PCA on PC12 cells was detected after PC12 cells were pretreated with the different contentions of PCA. Autophagy-related marker Beclin1 protein level was detected by Western blotting method to investigate the protective mechanism of PCA. Results Aggregated white Aβ1-42 mass was stable at hour 12 and 24, and showed no significant difference between the two time points, the cell damage rate being 40%. Therefore, we defined culturing time being 12 and 24 hours as the modeling condition of AD model. The cell viability was increased with 200-800 μmol/L of PCA after culturing for 24 hours(P<0.01) , and the Western blotting results showed that the Beclin1 protein expression was up-regulated by PCA. Conclusion PCA prevents PC12 cells from Aβ1-42-induced toxicity, the mechanism being related with the increase of cellular autophagy.

OBJECTIVETo detect potential mutations of the spastic ataxia of Charlevoix-Saguenay (SACS) gene in a pedigree affected with autosomal recessive spastic ataxia of Charlevoix-Saguenay (ARSACS).

METHODSGenomic DNA was extracted from peripheral blood samples of the proband and her family members. All exons and flanking sequences of the SACS gene were analyzed by high-throughput sequencing. Suspected mutations were verified with Sanger sequencing.

RESULTSNext generation sequencing revealed novel compound heterozygous mutations of the SACS gene, namely c.13085T to G (p.I4362R) and c.5236dupA (p.T1746fs), in the proband, which were respectively derived from her parents. The mutations were confirmed by Sanger sequencing.

CONCLUSIONThe c.5236dupA (p.T1746fs) and c.13085T to G (p.I4362R) mutations of the SACS gene probably underlie the ocular symptoms and hearing loss in the proband.

Objective To observe the effect of Kinesio Taping with lattice shapes on pregnancy-related low back pain (PLBP). Methods From March, 2017 to April, 2018, 56 patients with PLBP were randomly divided into the control group (n = 28) and experimental group (n = 28). Both groups received the core stability training, while the experimental group accepted Kinesio Taping with lattice shapes additionally. They were assessed with Visual Analogue Scale (VAS), Roland-Morris Dysfunction Questionnaire (RMDQ), range of lumbar activity and torso angle before, three days and two weeks after treatment. Results The range of lumbar activity improved significantly in both groups (t > 6.327, P < 0.01) three days after treatment, while the scores of VAS and RMDQ, and the torso angle improved significantly in the experimental group (t > 4.862, P < 0.001). The scores of VAS and RMDQ, the range of lumbar activity, and the torso angle improved significantly in both groups two weeks after treatment (P < 0.001), and improved more in the experimental group than in the control group (P < 0.05). Conclusion Kinesio Taping with lattice shapes combined with core stability training can further reduce the lower back pain and improve the function for the PLBP patients.

Tinosporae Radix， as a traditional Chinese medicinal herb， is the dried root tuber of Tinospora sagittata or T. capillipes. It was first recorded in the Compendium of Materia Medica Supplement in the Qing Dynasty and included in the previous edition of the Chinese Pharmacopoeia. Tinosporae Radix is excavated in autumn and winter and used after removing fibrous roots， washing， and drying. It is indicated for sore throat， carbuncle boils poison， waist and abdominal pain， and various heat syndromes and is commonly used to treat chronic inflammation. Its efficacy is significantly known as “broad-spectrum antibiotics in Zhuang medicine”. Tinosporae Radix is a traditional Chinese medicinal herb often taken by Zhuang and Yao nationalities in Guangxi province and has a wide range of application and development values and research significance. Modern studies have shown that Tinosporae Radix contains diterpenoids， alkaloids， sterols， anthraquinones， glycosides， fatty acids， volatile oils， and other compounds， which have many pharmacological activities such as anti-inflammatory and analgesic， antibacterial and antibacterial， antioxidant， anti-diabetic， and anti-tumor and anti-cancer effects， and it has achieved good efficacy in inhibiting inflammation and treating sore throat and other diseases. In recent years， there have been many research reports on the status， chemical constituents， pharmacological action， clinical application， and quality evaluation of Tinosporae Radix resources， but there is no systematic review and introduction at present. By consulting the literature and combining it with modern research， this paper systematically summarizes and collates Tinosporae Radix resources to provide guidance for the comprehensive development and utilization of Tinosporae Radix resources and subsequent in-depth study.
