Objective:To investigate whether vestibular-evoked myogenic potentials (VEMP) can be used to assess brainstem and its supplementary diagnostic value in patients with early-stage Parkinson′s disease (PD).Methods:A total of 123 patients with early-stage PD (PD group) diagnosed in the Department of Neurology of the Second Affiliated Hospital of Soochow University from January 2019 to January 2022 were consecutively enrolled, and 122 healthy controls (healthy control group) were included. Cervical VEMP (cVEMP) and ocular VEMP (oVEMP) examinations were performed on all subjects. VEMP parameters between the 2 groups were compared, and receiver operating characteristic curve was used to evaluate the auxiliary diagnostic efficacy of VEMP for early-stage PD. Correlations between VEMP parameters and motor and non-motor symptoms such as autonomic dysfunction were analyzed in the PD group using Spearman correlation analysis.Results:Bilateral latencies of cVEMP [left P1 latency (Lp13): 19.0 (16.4, 20.9) ms vs 13.1(12.0, 14.2) ms, Z=-11.18, left N1 latency (Ln23): 27.4 (24.6, 29.9) ms vs 21.2 (19.8, 23.0) ms, Z=-10.14; right P1 latency (Rp13): 18.8 (16.2, 20.9) ms vs 13.0 (11.7, 14.1) ms, Z=-10.84, right N1 latency (Rn23): 27.7 (24.3, 29.7) ms vs 21.1 (19.6, 22.9) ms, Z=-10.50] and bilateral latencies of oVEMP [left N1 latency (Ln10): 12.7 (10.7, 14.4) ms vs 10.4 (9.7, 11.4) ms, Z=-8.02, left P1 latency (Lp15): 16.5 (15.1, 18.3) ms vs 14.5 (13.4, 15.3) ms, Z=-7.96; right N1 latency (Rn10): 12.8 (11.4, 14.0) ms vs 10.5 (9.7, 11.5) ms, Z=-8.85, right P1 latency (Rp15): 16.7 (15.3, 18.3) ms vs 14.4 (13.3, 15.1) ms, Z=-9.39] of the PD group significantly prolonged compared to the healthy control group (all P<0.001). Compared to the healthy control group, the area under the curve (AUC) values of Lp13, Ln23, Rp13 and Rn23 of cVEMP in the PD group were all greater than 0.7, and the AUC values of Lp13 and Rp13 in the PD group were greater than 0.9 (all P<0.001); the AUC values of Ln10, Lp15, Rn10, and Rp15 of oVEMP in the PD group were all greater than 0.7 (all P<0.001). The Rn10-p15 corrected amplitude in PD patients was positively correlated with levodopa equivalent dose ( r=0.21, P=0.020). The Rn10 in PD patients was positively correlated with the Non-Motor Symptoms Questionnaire scores ( r=0.21, P=0.023). The Lp13-n23 corrected amplitude was negatively correlated with the Scale for Outcomes in Parkinson′s Disease-Autonomic scores ( r=-0.20, P=0.023). There was no significant correlation between VEMP parameters and Unified Parkinson′s Disease Rating Scale part Ⅲ score ( P>0.05). Conclusion:VEMP, especially cVEMP, as a non-invasive neuroelectrophysiological index, is an objective marker for brainstem damage and could be used for screening early-stage PD patients.

In China, the survival rate of liver cancer remains low while the mortality rate is high. Effectively reducing the burden of liver cancer is still a major challenge in the field of public health and chronic disease prevention in the Chinese population. Optimizing screening strategies for liver cancer remains a profound approach to secondary prevention worthy of continuous exploration. To address this pressing issue, the Bureau of Disease Control and Prevention of the National Health Commission commissioned this guideline. The National Cancer Center of China initiated the guideline development and convened a multidisciplinary expert panel and working groups. Following the World Health Organization Handbook for Guideline Development, this guideline integrated the most up-to-date evidence of liver cancer screening, China's national conditions, and existing practical experience in liver cancer screening. Evidence-based recommendations on the target population, screening technologies, surveillance strategies, and other key points across the process of liver cancer screening and surveillance management were provided. This guideline would help standardize the practice of liver cancer screening in China.

Objective:To explore the clinical effect of Bobath manipulation combined with traditional Chinese medicine fumigation and intradermal acupuncture on shoulder hand syndrome(SHS) after stroke.Methods:From April 2017 to August 2019, 80 patients with SHS after stroke admitted to the People's Hospital of Deqing County were selected, and they were divided into control group and observation group according to the random digital table method, with 40 cases in each group.The control group was treated by Bobath therapy, and the observation group was treated by Bobath therapy combined with acupuncture(intradermal acupuncture) and traditional Chinese medicine fumigation.After 8 weeks of treatment, the ROM scale, FMA scale, BI scale and VAS scores were used to evaluate the improvement in the mobility of the shoulder and wrist joints, motor function of the upper limbs, quality of life and pain, and the clinical efficacy of the two groups was compared.Results:Compared with before treatment, the ROM scale score of all dimensions of shoulder and wrist mobility, FMA scale score and BI scale score of all patients after treatment increased significantly, and the VAS score decreased significantly, the differences were statistically significant(all P<0.05). Compared with the control group after treatment, the improvement of the indicators mentioned above of the observation group were better[shoulder joint flexion ROM score: (154.83±25.63)points vs.(133.82±22.03)points; shoulder joint abduction ROM score: (152.36±25.68)points vs.(133.35±19.96 )points; shoulder joint external rotation ROM score: (75.87±14.69)points vs.(60.82±16.57 )points; wrist joint palm flexion ROM score: (73.94±14.37)points vs.(57.37±9.47)points; wrist joint back extension ROM score: (60.83±7.61)points vs.(42.27±6.37 )points; FMA scale score: (45.74±6.82)points vs.(34.19±4.07)points; BI scale score: (70.36±12.09)points vs.(58.70±12.53)points; VAS score: (1.05±0.49)points vs.(3.37±1.14)points, t=3.703, 3.715, 3.257, 5.576, 7.964, 3.037, 8.746, 3.153, all P<0.05]. The total effective rate of the observation group was significantly higher than that of the control group[97.5%(39/40) vs.62.5%(25/40), χ 2=15.313, P<0.05)]. Conclusion:The combination of Bobath therapy with traditional Chinese medicine fumigation and intradermal acupuncture can improve the pain degree, joint mobility disorder, upper limb motor function and quality of life of SHS patients, the efficacy is better than single Bobath therapy.The clinical effect is accurate, and it is worthy of further promotion and application.

Various sleep disorders are the most common group of non-motor symptoms in Parkinson's disease (PD),which can also occur during the prodromal phase of PD.All types of sleep disturbances may be encountered in PD:insomnia,excessive daytime sleepiness,rapid eye movement sleep behavior disorders,restless legs syndrome and sleep-disordered breathing.Standardized management of PD patients with sleep disturbance will be beneficial to improve the overall quality of diagnosis,treatment and prognosis.More high-quality clinical trials need to be carried out in the future.

Objective To evaluate the feasibility of the combination of amplification refractory mutation system (ARMS) and quantitative real-time polymerase chain reaction (PCR) method in fast detection of clarithromycin resistance of Helicobacter pylori (H.pylori) in gastric mucosa.Methods A total of 150 gastric mucosal specimens with positive H.pylori culture were collected from the H.pylori positive patients who failed in H.pylori eradication from January to August in 2013.The drug resistant gene mutation types of H.pylori in these samples were detected by quantitative real-time PCR based on ARMS.And the accuracy was confirmed by sequencing.The clarithromycin resistance of H.pylori was determined by E-assay.Chi-square test was used for statistical analysis.Results Among 149 gastric mucosal specimens (one specimens without wild type or mutation type had been eliminated),the results of quantitative real-time PCR based on ARMS of two samples were not consistent with the results of sequencing;the consistent rate was 98.7％ (147/149).Among 149 specimens with positive H.pylori culture,104 samples (69.8％) were clarithromycin resistance.In 101 samples the clarithromycin resistance was detected by quantitative real-time PCR based on ARMS;the consistent rate was 97.1％ (101/104).Both E-assay and clarithromycin resistant rate detected by E-assay or quantitative real-time PCR based on ARMS was 69.8％ (104/149) and 67.8％ (101/149),respectively,and the difference was not significant (x2 =0.141,P=0.932).Conclusion The combination of ARMS and quantitative real-time PCR method in fast detection of clarithromycin resistance of H.pylori in gastric mucosa is strongly feasible and highly consistent has high consistent rate with sequencing and E-assay.
