Objective:To investigate the clinical effects of electroacupuncture assisted with facial expression muscle control rehabilitation training in the treatment of patients with severe idiopathic facial paralysis.Methods:A total of 130 patients with severe idiopathic facial paralysis who met inclusion criterion were chosen and randomly divided into 2 groups, 65 patients in each, from January 2017 to December 2019 in our hospital. The control group were treated with facial expression muscle control rehabilitation training and western medicine, and the experiment group with electroacupuncture on the basis of the control group. Both groups were treated for 8 weeks and followed up for 6 months. The facial nerve function was evaluated by H-B scale and facial nerve sunny brook scale the quality of daily life was evaluated by Facial Disability Index Physical Function (FDIP) scale and Facial Disability Index Social Function (FDIS) scale. The latency/M wave amplitude of motor evoked action on orbicularis oculi muscle and orbicularis ORIS muscle were measured by EMG evoked potential instrument. The occurrence of hemifacial spasm during follow-up was recorded. The clinical effective rates were evaluated.Results:The total effective rate of experiment group was 92.31% (60/65), which was significantly higher than that of the control group 76.9% (50/65) ( χ2=6.495, P=0.039). The H-B scale scores of experiment group after treatment were significantly less than that of the control group ( t=3.438, P<0.01). The facial nerve sunny brook scale scores of experiment group after treatment were significantly more than that of the control group ( t=2.674, P=0.032). The FDIP scores of experiment group after treatment were significantly less than that of the control group ( t=3.986, P<0.01). The FDIS scores of experiment group after treatment were significantly more than that of the control group ( t=4.621, P<0.01). The NCV latency of orbicularis oculi muscle [(2.51 ± 0.27) ms vs. (2.82 ± 0.46) ms, t=4.258] and orbicularis oris muscle [(2.97 ± 0.22) ms vs. (3.35 ± 0.40) ms, t=4.783] of observation group were significantly lower than those in the control group ( P<0.01). The M wave amplitudes of orbicularis oculi muscle [(1.83 ± 0.45) mV vs. (1.30 ± 0.39) mV, t=3.827] and orbicularis oris muscle [(2.58 ± 0.60) mV vs. (1.97 ± 0.36) mV, t=4.017] of observation group were significantly higher than those in the control group ( P<0.01). The incidence of facial spasm with follow-up of experiment group for 4.62% (3/65) was significantly lower than that of the control group for 15.38% (10/65) ( χ2=9.271, P=0.033). Conclusion:Electroacupuncture assisted with facial expression muscle control rehabilitation training in the treatment of patients with severe idiopathic facial paralysis can relieve clinical symptoms, improve facial nerve function, improve the quality of daily life and be helpful to reduce the facial spasm risk.

Objective To investigate the possible associations of two polymorphisms (5-HTTLPR and STin2VNTR)of the serotonin transporter gene with alcohol use disorders (AUD).Methods 281 AUD cases (AUDIT score≥ 10) and 277 healthy controls (AUDIT score ≤5) were recruited in this study.All participants were genotyped using the PCR technique.Results The frequency of the L-allele of the 5-HTTLPR was 39.01％,and the 10-allele of STin2VNTR was 8.42％ in this population,the allele frequencies of both polymorphisms were consistent with Asian normal populations.No significant association was observed between 5-HTTLPR and AUD,but the genotypic and allele frequencies of the STin2VNTR were significant different between two groups even after Bonferroni adjustment,the 12 repeat allele of the STin2VNTR was significantly associated with the risk effect for AUD.Haplotype analysis for those two polymorphisms revealed no association between 4 haplotype combinations and AUD.Conclusion There is no relationship between 5-HTTLPR and AUD.The STin2VNTR polymorphism of 5-HTT may play a role in the pathogenesis of AUD.

Objective To investigate the prognosis relevant factors of laryngeal squamous cell carcinoma (LSCC).Methods From January 2013 to December 2013,the clinical data of 71 patients with LSCC who were initially treated in Zhejiang Cancer Hospital were retrospectively analyzed.Results Univariate analysis showed that there were statistically significant differences in survival rate between the group of supraglottic type and glottic type (60.0% vs.86.3% ,χ2 =6.284,P<0.05),the group of N0 and N+(41.7% vs.86.4% ,χ2 =16.803,P<0.01), the group of early and late stage(93.6% vs.50.0% ,χ2 =19.854,P<0.01).There were no statistically significant differences in survival rate between the group of age ≤50,>50-60,>60-70 and >70(88.9% vs.88.2% vs. 79.3% vs.62.5% ,χ2 =3.909,P>0.05),the group of T1+T2 and T3+T4(83.6% vs.62.5% ,χ2 =3.623,P>0.05),the group of high,medium,low differentiated and unsigned(75.0% vs.69.7% vs.83.3% vs.91.7% ,χ2 =3.780,P>0.05),the group of surgery,radiotherapy and surgery+radiotherapy (74.3% vs.90.9% vs.71.4% , χ2 =2.437,P>0.05).Multivariate analysis showed that age( P =0.003),treatment( P =0.048) had significant effect on the prognosis of patients,but tumor location(P=0.766),T stage(P=0.677),N stage(P=0.482),clinical stage(P=0.825),the degree of pathological differentiation(P=0.206) had no significant effect on the prognosis of patients.Conclusion More aggressive treatment should be supplied for patients with N+,advanced clinical stage and age whom the prognosis are usually poor. In addition, the proportion of tracheal tube extraction should be appreciated.

Objective:To evaluate the performance of magnetic beads extraction method (MGE) for the measurement of catecholamine metabolites by liquid chromatography tandem mass spectrometry.Methods:This is a methodological evaluation study. The linearity, limit of quantitation, recovery, precision, and matrix effect of catecholamine metabolites 3-methoxyepinephrine (MN), 3-methoxynorepinephrine (NMN) and 3-methoxytyramine (3-MT) extracted by MGE method were evaluated according to CLSI C62-A. Consensus of method development and validation of liquid chromatography-tandem mass spectrometry in clinical laboratories and other guidelines, 132 clinical residual plasma samples were collected and extracted by automated MGE and traditional solid phase extraction (SPE) method to compare the harmonization of the two extraction methods.Results:The linearity of MN, NMN and 3-MT extracted by automated MGE was>0.99, and the LOQ for MN, NMN and 3-MT were 0.033 5 nmol/L, 0.054 7 nmol/L and 0.011 0 nmol/L, respectively. The repeatability of MN, NMN and 3-MT were 1.3%-5.1%, 2.2%-5.6% and 1.7%-7.1%, respectively. The total imprecision in the laboratory were 1.5%-8.2%, 2.2%-7.7%, 2.1%-11.2%. Although the absolute recovery is low, the average relative recoveries of MN, NMN and 3-MT were 91.5%-108.5%, 92.0%-108.6%, and 89.3%-104.1%, respectively, and the percentage deviation from the expected concentration was within 15%. After isotope internal standard correction, the relative matrix effect is close to 100%, which can compensate for the potential matrix effect. The results of MGE and SPE of MN, NMN and 3-MT showeda good correlation (correlation coefficient r>0.99). The average relative deviations of MN, NMN and 3-MT were 0.2%, -1.4% and 1.0%, respectively. Conclusion:The automatic MGE method hasa good performance in extracting catecholamine metabolites, and is expected to be used in high-throughput analysis of samples in clinical in the future.
