Electroencephalographic microstates in vestibular schwannoma patients with tinnitus / 南方医科大学学报

OBJECTIVE@#To explore the biomarkers of tinnitus in vestibular schwannoma patients using electroencephalographic (EEG) microstate technology.@*METHODS@#The EEG and clinical data of 41 patients with vestibular schwannoma were collected. All the patients were evaluated by SAS, SDS, THI and VAS scales. The EEG acquisition time was 10-15 min, and the EEG data were preprocessed and analyzed using MATLAB and EEGLAB software package.@*RESULTS@#Of the 41 patients with vestibular schwannoma, 29 patients had tinnitus and 12 did not have tinnitus, and their clinical parameters were comparable. The average global explanation variances of the non-tinnitus and tinnitus groups were 78.8% and 80.1%, respectively. The results of EEG microstate analysis showed that compared with those without tinnitus, the patients with tinnitus had an increased frequency (P=0.033) and contribution (P=0.028) of microstate C. Correlation analysis showed that THI scale scores of the patients were negatively correlated with the duration of microstate A (R=-0.435, P=0.018) and positively with the frequencies of microstate B (R=0.456, P=0.013) and microstate C (R=0.412, P=0.026). Syntax analysis showed that the probability of transition from microstate C to microstate B increased significantly in vestibular schwannoma patients with tinnitus (P=0.031).@*CONCLUSION@#EEG microstate features differ significantly between vestibular schwannoma patients with and without tinnitus. This abnormality in patients with tinnitus may reflect the potential abnormality in the allocation of neural resources and the transition of brain functional activity.

Clinical diagnosis and surgical management of 110 cases of facial nerve schwannomas / 中华耳鼻咽喉头颈外科杂志

Objective@#To elucidate the clinical behavior, causes of misdiagnosis, surgical management, and outcomes of facial nerve schwannomas (FNS).@*Methods@#A retrospective review in Chinese People′s Liberation Army General Hospital from January 1, 2002 to December 31, 2015 was carried out and evaluated 110 patients with FNS, including 50 males and 60 females, aged 16-67 years old. The appropriate surgical strategy was selected based on each patient′s clinical manifestations, facial nerve function, and imaging characteristics. After surgery, patients received follow-up visits to assess their facial nerve functions, with the effect of treatment compared to the reality before surgery. The Kruskal-Wallis H test was used to distinguish between the pre- and post-operation facial nerve functions in patients who had different facial nerve functions before the operations.@*Results@#110 cases of FNS mainly presented with facial paralysis, hearing loss, tinnitus, otalgia, dizziness, and facial spasm. 20 of the cases were misdiagnosed as Bell′s Palsy, 6 were mistaken for chronic otitis media/cholesteatoma with radical mastoidectomy, 3 were mistaken for Meniere′s disease, 1 was misdiagnosed as petrous bone cholesteatoma, and 4 were mistaken for acoustic neuroma. 81.8 % (90/110) of the patients had multiple segments of the facial nerve, including the vertical segment of the facial nerve, accounting for 65.5% (72/110), followed by the labyrinthine/geniculate segment, for 61.8% (68/110), and the horizontal segment, for 55.5% (61/110). The appropriate surgical approaches were chosed based on the sizes and scopes of the tumors evaluated by imaging: transmastoid approach in 73 cases, translabyrinthe approach in 14 cases, middle cranial fossa approach in 13 cases, retrosigmoid approach in 3 cases, transmastoid-middle cranial fossa approach in 3 cases, and transmastoid-neck approach in 4 cases, with all the patients undergoing a total/subtotal resection of the tumor. Eighty-seven patients had their facial nerves reconstructed. Among them, 6 received facial nerve end-to-end anastomosis, 55 received great auricular nerve graft, and 26 were subjected to facial nerve-hypoglossal nerve anastomosis. Because of long histories, facial muscle atrophies, or other reasons, the remaining patients were not received facial nerve reconstruction. The House-Brackmann(H-B) grading scale was used to evaluate the facial nerve function pre- and post-operation. Patients with better facial nerve functions and shorter history of facial paralysis before operation would get relatively better facial nerve function. The before and after operation comparisons revealed that the recovery of the facial nerve functions in patients with H-B Ⅰ-Ⅲ was better than the improvement in patients with H-B Ⅳ-Ⅴ. The difference was statistically significant (Kruskal-Wallis H test, H=8.508, P<0.05).@*Conclusions@#The diagnosis of patients with unknown facial paralysis, hearing loss, and tinnitus should take into account the possibility of FNS. CT and other imaging examinations of the temporal bone can avoid misdiagnosis and determine the tumor size and extent of lesions, as well as provide the basis for the choice of the surgical approach. After tumors have been completely resected, facial nerve reconstruction can be performed simultaneously, according to the defect of the nerve.

Effect of early acupuncture intervention on post-stroke depression: a randomized controlled trial / 中国针灸

OBJECTIVE@#To observe the effects of conventional drug therapy combined with acupuncture and conventional drug therapy on the morbidity of post-stroke depression and recovery of neurological function in patients with acute stroke, and provide new ideas for prevention and treatment of post-stroke depression.@*METHODS@#Sixty patients were randomly divided into an observation group and a control group, 30 cases in each one.Conventional drug therapy was given in the control group;on the basis of conventional drug therapy,acupuncture was applied at Baihui (GV 20), Sishencong (EX-HN1), Neiguan (PC 6), Hegu (LI 4), Taixi (KI 3), etc. The treatment was given once every day, 6 times a week for 4 weeks in the two groups. The 24 Hamilton depression rating scale (HAMD), modified Edinburgh-Scandinavian stroke scale (MESSS) scores were recored before treatment, after 1 week of treatment, and after 4 weeks of treatment in the two groups,and the morbidity of post-stroke depression was compared between the two groups.@*RESULTS@#After 1 week of treatment, the HAMD scale scores of the two groups were higher than those before treatment (both 0.05). The MESSS scores were lower than those after 1 week of treatment in the two groups (both <0.05), and the score in the observation group was significantly lower than that in the control group (<0.01). After 4 weeks of treatment, the morbidity of post-stroke depression in the observation group was 23.3% (7/30), which was lower than 66.7% (20/30) in the control group (<0.05).@*CONCLUSION@#Early acupuncture intervention on stroke patients can not only promote the recovery of neurological function, but also reduce the morbidity of post-stroke depression effectively.

According to Sanna′s classification, 40 out of the 90 cases were supralabyrinthine, five infralabyrinthine, four infralabyrinthine-apical, 25 massive and 16 apical. Five cases underwent transmastoid and retrolabyrinthine approach, translabyrinthine approach was performed on six patients, 19 cases underwent subtotal petrosectomy, seven cases underwent transotic approach, 41 cases underwent middle fossa approach, combined transmastoid/middle fossa approach was performed on 11 cases, translabyrinthine and sphenoid sinus approach were performed on one case. Supralabyrinthine cases mainly applied middle fossa approach (77.5%, 31/40) and combined transmastoid and middle-fossa approach(20.0%, 8/40). Combined transmastoid-retrolabyrinthine approach were applied for all the infralabyrinthine cases (100.0%, 5/5). Infralabyrinthine-apical cases mainly applied subtotal petrosectomy (75.0%, 3/4). Massive cases mainly applied subtotal petrosectomy (60.0%, 15/25), transcochlear approach (20.0%, 5/25), and translabyrinthine approach (16.0%, 4/25). Apical cases mainly applied middle fossa approach (62.5%, 10/16).@*Results@#Ninty percent (18/20) of the patients who had preoperative grade Ⅰ facial nerve function maintained in the postoperative period. Out of 90 cases, only 11 cases received open cavity, and the rest cases received cavityobliteration. There were three cases of recurrence, four cases of cavity infection, three cases of cerebrospinal fluid leakage, and one case of epidural hematoma, who all received surgeries.@*Conclusions@#Sanna′s classification should be used to classify different kinds of PBC cases, choose the best surgical approach for different cases, and preserve or repair facial function during removal of PBC, and thus reduce recurrence and complications.

A novel CD36 mutation T538C (Trp180Arg) results in CD36 deficiency and establishment of a genotyping method for the novel mutation based on sequence-specific primer PCR / 中华医学遗传学杂志

<p><b>OBJECTIVE</b>To explore the molecular basis for a CD36 deficiency individual and distribution of CD36 gene mutation in Guangxi population.</p><p><b>METHODS</b>A female individual was studied. CD36 phenotype was detected by monoclonal antibody immobilization of platelet antigens assay (MAIPA) and flow cytometry (FCM). The coding regions of the CD36 gene were sequenced. A DNA-based polymerase chain reaction-sequence specific primer (PCR-SSP) assay was used to verify the identified mutation. Cell lines expressing the mutant and wild-type CD36[CD36(MT) and CD36(WT)] were established, with the expression of CD36 determined by Western blotting. The distribution of CD36 gene mutation was investigated among 1010 unrelated individuals with the PCR-SSP assay.</p><p><b>RESULTS</b>Both MAIPA and FCM assays showed that the patient had type II CD36 deficiency. DNA sequencing showed that she has carried a heterozygous mutation T538C (Trp180Arg) in the exon 6 of CD36. Sequencing of cDNA clone confirmed that there was a nucleotide substitution at position 538 (538T>C). Western blotting also confirmed that the CD36 did not express on the CD36(MT) cell line that expressed the 538C mutant, but did express on the CD36(WT) cell line. The novel CD36 mutation T538C was further verified with 100% concordance of genotyping results by DNA-based PCR-SSP assay and 1010 unrelated individuals. No CD36 538C allele was detected among the 1010 individuals.</p><p><b>CONCLUSION</b>This study has identified a novel CD36 mutation T538C(Trp180Arg)(GenBank: HM217022.1), and established a genotyping method for the novel sequence-specific primer PCR. The novel mutation is rare in Guangxi and can cause type II CD36 deficiency.</p>

YANG's pricking-cupping therapy for knee osteoarthritis: a multi-center randomized controlled trial / 中国针灸

<p><b>OBJECTIVE</b>To evaluate the clinical efficacy of YANG's pricking-cupping therapy for knee osteoar thritis (KOA). Methods This was a multi-center randomized parallel controlled trial. One hundred and seventy one patients with KOA were randomly allocated to a pricking-cupping group (89 cases) and a conventional acu puncture group (82 cases). Neixiyan (EX-LE 4), Dubi (ST 35) and ashi points were selected in the two groups. Patients in the pricking-cupping group were treated with YANG's pricking-cupping therapy; the seven-star needles were used to perform pricking at acupoints, then cupping was used until slight bleeding was observed. Patients in the conventional acupuncture group were treated with semi-standardized filiform needle therapy. The treatment was given for 4 weeks (from a minimum of 5 times to a maximum of 10 times). The follow-up visit was 4 weeks. The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and the visual analogue scale (VAS) were adopted for the efficacy assessments.</p><p><b>RESULTS</b>The pain score, stiffness score, physical function score and total score of WOMAC were all reduced after 4-week treatment and during follow-up visit in the two groups (all P<0. 0001). Except that the difference of stiffness score between the two groups was not significant after 4-week treatment (P>0. 05), each score and total score of WOMAC in the pricking-cupping group were lower than those in the conventional acupuncture group after 4-week treatment and during follow-up visit (P<0. 0001, P<0. 01). After 2-week treatment, 4-week treatment and during follow-up visit, the VAS was all reduced compared with that before treatment (all P<0. 0001) ; with the increase of the treatment, the reducing trend of VAS was more significant (P<0. 0001). The scores of VAS in the pricking-cupping group were lower than those in the conventional acupuncture group after 4-week treatment and during follow-up visit (P < 0. 01, P <0. 0001). CONCLUSION The YANG's pricking-cupping and conventional acupuncture therapy can both significantly improve knee joint pain and function in patients with KOA, which are relatively safe. The pricking cupping therapy is superior to conventional acupuncture with the identical selection of acupoints.</p>

The expression of hypoxia induced factor-1α signaling in nonacoholic fatty liver disease in rats / 中华内分泌代谢杂志

Objective To investigate the role of hypoxia induced factor-1 α (HIF-1 α) signaling pathway in development of nonacoholic fatty liver disease (NAFLD) by using a rat model.Methods Forty SD rats were randomly divided into 5 groups (normal control group,4 weeks model group,8 weeks model group,12 weeks model group,and 16 weeks model group according to random number table).NAFLD model was induced by high fat diet.Serum biochemical parameters and liver histological examinations were observed.The HIF-1α,peroxisome proliferator-activated receptor α (PPARα),and nuclear factor-κB (NF-κB) mRNA transcriptions of liver tissue were detected with realtime PCR.Results Compared with the control group,a remarkable rise of serum alanine amiotransferase,triglyceride,cholesterol,and reduction of high density lipoprotein-cholesterol were observed in rats treated with high fat diet after 12 weeks and 16 weeks (P＜0.05).Compared with model group,steatosis,grade of inflammation,and degree of fibrosis in the liver were also significantly aggravated.Fed with high fat diet for 8 weeks,the expression of HIF-1α was significantly higher than that in the control group;the expression of PPARα in 4 weeks group was significantly higher than that in the control group.The expression of PPARα was again significantly elevated in 16 weeks group (P＜0.05);NF-κB expression was increased gradually with high fat diet (P＜0.05).The expression of HIF-1 α mRNA was related with PPARα (r =0.82,P＜0.05) and NF-κB (r =0.67,P＜0.05),and PPARα mRNA was related with NF-κB (r =0.78,P＜0.05).Conclusion HIF-1 α signaling may regulate PPARα/NF-κB and seems to be related with development of NAFLD.

Study on the Orthogonal Optimization of Acupuncture, Tuina and Ultrasonic Treatments for Upper Limb Motor Dysfunction after Cerebral Infarction / 上海针灸杂志

Objective To develop a optimized rehabilitation protocol for acupuncture, Tuina and ultrasonic treatments of upper limb motor dysfunction after cerebral infarction.Methods An orthogonal design with three factors (acupuncture as factor A, Tuina as factor B and ultrasound as factor C) and two levels was used. Eighty cerebral infarction patients with upper limb motor dysfunction were randomly allocated to eight groups, 10 cases each. The National Institute of Health Stroke Scale (NIHSS) score and the simplified Fugl-Meyer Assessment (FMA) score for upper limb motor function were recorded after four weeks of treatment. Results There were no statistically significant pre-treatment differences in the NIHSS score and the FMA score for the upper limb between the groups (P>0.05). For an improvement in NIHSS, factors A and B were both significant (bothP0.05). Factors A, B and C were all significant for an improvement in the FMA score for the upper limb (P<0.05,P<0.01,P<0.05). A2B1C1 was the optimal protocol.Conclusions A combination of bilateral acupuncture, Tuina and ultrasound is an optimized protocol for treating upper limb motor dysfunction after cerebral infarction. It can effectively reduce upper limb motor dysfunction.
