In the present study, the fluoro-gold(FG) and horseradish peroxidase(HRP) combined tracing method was used to investigate the localization of parasympathetic preganglionic neurons and ascending projection neurons in lumbosacral spinal cord of the rat. FG was injected into the lateral parabrachial nucleus(PBL) or into Barrington's nucleus on one side, and HRP was applied to the contralateral pelvic nerve. The retrogradely FG-labeled neurons were found in bilateral "visceral field" at segments L_5-S_2, and the majority of them were concentrated in the intermediolateral nucleus (IML), and the dorsal commissural nucleus (DCN). In addition to these areas, some labeled neurons were also observed in bilateral lamina I and lateral spinal nucleus (LSN). The parasympathetic preganglionic neurons labeled with HRP were seen in the IML at segments L_6-S_1, occasionally appeared in the intercalated nucleus. In the IML area, HRP-labeled parasympathetic preganglionic neurons were located in its ventral part, however, the localization of FG-labeled neurons projected to the PBL and Barrington's nucleus were mainly found in the dorsal and dorsomedial part of the IML, and a few FG-labeled cells were scattered among HRP-labeled cells. Based on the present and other investigations, the nomenclature, organization and function of the IML and the composition of the LSN were discussed.

Objective To investigate the effects of levodopa benserazide hydrochloride combine with dl-3-butyl phthalide capsule on patient's limbs function after stroke. Methods Ninety patients with stroke were randomly divided into rehabilitation group,treatment group and control group,and 30 cases for each group. Patients in rehabilitation group were treated with exercise therapy,in treatment group were given exercise therapy and levodopa Benserazide and Dl-3-butylphthalide capsules,and in control group were given placebo treatment. Adult hemiplegic motor function score(FMA)and motor function assessment scale(MAS)were used to assess the motor function and lower extremity function before treatment and 8 weeks after treatment. Results Before treatment,FMA and MAS in rehabilitation group,treatment group and control group were(22. 6 ± 3. 6), (23. 1 ± 2. 5)and(20. 3 ± 2. 9),and(1. 6 ± 0. 6),(2. 1 ± 0. 5),(1. 7 ± 0. 9),respectively. There was no significant differences between the two groups( F = 1. 64,P > 0. 05;F = 1. 66,P > 0. 05). After 8 weeks of treatment,FMA and MAS in rehabilitation group and treatment group were(60. 6 ± 3. 5),(14. 6 ± 1. 1),and (75. 7 ± 4. 5),(17. 7 ± 4. 5),significant improved more than that before treatment(t = 1. 738,1,716,1. 732 respectively;P < 0. 05). Meanwhile,patients in the treatment group improved more than that in rehabilitation group(P < 0. 05),and they were superior to patients in control group((31. 0 ± 3. 6),(5. 5 ± 1. 1);P < 0. 05). Conclusion Benserazide combined with dl-3- butyl phthalide capsule can further improve the limbs function.

In this paper we present a new method of combining Independent Component Analysis (ICA) and Wavelet de-noising algorithm to extract Evoked Related Potentials (ERPs). First, the extended Infomax-ICA algorithm is used to analyze EEG signals and obtain the independent components (Ics); Then, the Wave Shrink (WS) method is applied to the demixed Ics as an intermediate step; the EEG data were rebuilt by using the inverse ICA based on the new Ics; the ERPs were extracted by using de-noised EEG data after being averaged several trials. The experimental results showed that the combined method and ICA method could remove eye artifacts and muscle artifacts mixed in the ERPs, while the combined method could retain the brain neural activity mixed in the noise Ics and could extract the weak ERPs efficiently from strong background artifacts.

Objective:To evaluate the efficacy of string-shuttling assisted Endobutton technique for acute acromioclavicular dislocation of Rockwood Type Ⅲ.Methods:From March 2018 to March 2019, 15 patients were treated at Department of Sports Medicine and Ankle & Foot, Central Hospital of Jiangmen for acute acromioclavicular dislocation of Rockwood Type Ⅲ. They were 10 men and 5 women, aged from 22 to 36 years (average, 30.6 years). The intervals from injury to surgery averaged 12.4 d (from 4 to 15 d). They were all treated by string-shuttling assisted Endobutton technique. Recorded were operation time, intraoperative blood loss, visual analogue scale (VAS) pain score and shoulder function at the final follow-up, and complications during follow-up.Results:This group was followed up for 8 to 12 months (9.8 months on average). Their operation time ranged from 85 to 115 min(101.1 min on average) and intraoperative blood loss from 50 to 100 mL (75.3 mL on average). Their VAS pain score decreased significantly from preoperative 7.0 (4.5, 8.0) to 0.0 (0.0, 1.0) at the final follow-up, and their Constant score increased significantly from preoperative 56.3±6.2 to 93.0±4.8 at the final follow-up (both P<0.05). No patient reported incision infection, peri-incision hypoesthesia, loss of reduction, breakage or loosening of implants, or fracture of the clavicle tunnel or the coracoid process. Conclusion:In the treatment of acute acromioclavicular dislocation of Rockwood Type Ⅲ, string-shuttling assisted Endobutton technique can effectively avoid such a complication as tunnel fracture, leading to fine functional recovery of the shoulder.

Objective:Hepatic steatosis has a high incidence in human immunodeficiency virus (HIV) infected people, and there is no effective non-invasive method to evaluate it. This study aims to evaluate the diagnostic value of non-invasive models for hepatic steatosis in this population.Methods:A single-center retrospective study was applied to evaluate: (1) the diagnostic value of controlled attenuation parameters (CAP) and hepatic steatosis index (HSI) in HIV-infected patients with hepatic steatosis; (2) the ability of the non-invasive model to distinguish hepatic steatosis caused by abnormal glucose and lipid metabolism and hepatic steatosis caused by hepatitis C virus infection; (3) the diagnostic value of the above models for hepatic steatosis in patients co-infected with HIV/hepatitis C virus. The diagnostic value of the model was analyzed and evaluated by diagnostic test and receiver operating characteristic curve.Results:(1) the diagnostic value of hepatic steatosis for HIV-infected patients: when CAP = 232 dB/m, the sensitivity and specificity were 89.2% and 78.1%, respectively; when HSI = 34, the sensitivity and specificity were 79.1% and 83.2%, respectively. (2) The ability to identify the causes of hepatic steatosis in HIV-infected patients: when CAP = 258dB/m, the sensitivity and specificity were 81.5% and 88.2%, respectively; when HSI = 37, the sensitivity and specificity were 70.7% and 92.4%, respectively. (3) The diagnostic value of hepatic steatosis in patients co-infected with HIV/hepatitis C virus: when CAP = 241 dB/m, the sensitivity and specificity were 80% and 71.4%, respectively; when HSI = 32, the sensitivity and specificity were 73% and 68.9%, respectively.Conclusion:CAP and HSI have superior diagnostic value for hepatic steatosis in patients infected with HIV.

OBJECTIVE:
To explore the genetic basis for a child manifesting with intellectual disability, language delay and autism spectrum disorder.
METHODS:
Genomic DNA was extracted from peripheral blood samples of the child and his family members, and subjected to whole exome sequencing. Candidate variants were verified by Sanger sequencing and interpreted according to the guidelines of the American College of Medical Genetics and Genomics.
RESULTS:
The child was found to harbor a heterozygous c.568C>T (p.Q190X) nonsense variant of the ADNP gene, which was not detected in either parent by Sanger sequencing.
CONCLUSION
The clinical and genetic testing both suggested that the child has Helsmoortel-van der Aa syndrome due to ADNP gene mutation, which is extremely rare in China.
