This study explored the ideas and methods of acupuncture for Guillain-Barré Syndrome （GBS） with the core principle of “to treat flaccidity， select the yangming （阳明） channel only”. The main pathological mechanism of GBS is deficiency of qi and blood in the yangming channel， malnutrition of all sinews， diminished spleen and stomach function leading to the production of pathogenic damp-heat qi， which obstructs the meridians， and gradually affects the liver and kidneys， consuming essence and damaging blood. Concurrently， dysfunction of the dumai （督脉） pivotal mechanism and lack of moisture in sinews and vessels result in symptoms such as skin numbness， paralysis， and muscle wastage. In clinical diagnosis and treatment， a combination of syndrome and channel differentiation is taken. Treatment primarily focuses on acupoints of yangming channel， aiming to supplement qi and blood， and acupoints of du mai are combined to open the vessel and fill the marrow. Specific acupoints are selected based on syndrome differentiation， providing comprehensive regulation to promote harmonization of qi and blood， relieve meridians， and the smooth generation and circulation of whole body fluids. This， in turn， enhances the strength of muscles and bones， and fosters a robust and freely moving body.

Objective:To explore whether transjugular intrahepatic portosystemic shunt (TIPS) can improve the prognosis of esophagogastric variceal bleeding (EGVB) combined with sarcopenia in cirrhotic patients.Methods:A retrospective cohort study was performed. A total of 464 cases with cirrhotic EGVB who received standard or TIPS treatment between January 2017 and December 2019 were selected. Regular follow-up was performed for the long-term after treatment. The primary outcome was transplantation-free survival. The secondary endpoints were rebleeding and overt hepatic encephalopathy (OHE). The obtained data were statistically analyzed. The t-test and Wilcoxon rank-sum test were used to compare continuous variables between groups. The χ2 test, or Fisher's exact probability test, was used to compare categorical variables between groups. Results:The age of the included patients was 55.27±13.86 years, and 286 cases were male. There were 203 cases of combined sarcopenia and 261 cases of non-combined sarcopenia. The median follow-up period was 43 months. The two groups had no statistically significant difference in follow-up time. There was no statistically significant difference in transplant-free survival between the TIPS group and the standard treatment group in the overall cohort ( HR=1.31, 95% CI: 0.97-1.78, P=0.08). The TIPS patient group with cirrhosis combined with sarcopenia had longer transplant-free survival (median survival: 47.76 vs. 52.45, χ2=4.09; HR=1.55, 95 CI: 1.01~2.38, P=0.04). There was no statistically significant difference in transplant-free survival between the two kinds of treatments for patients without sarcopenia ( HR=1.22, 95% CI: 0.78~1.88, P=0.39). Rebleeding time was prolonged in TIPS patients with or without sarcopenia combination (patients without combined sarcopenia: median rebleeding time: 39.48 vs. 53.61, χ2=18.68; R=2.47, 95 CI: 1.67~3.65, P<0.01; patients with sarcopenia: median rebleeding time: 39.91 vs. 50.68, χ2=12.36; HR=2.20, 95 CI: 1.42~3.40, P<0.01). TIPS patients had an increased 1-year OHE incidence rate compared to the standard treatment group (sarcopenia patients: 6.93% vs. 16.67%, χ2=3.87, P=0.049; patients without sarcopenia combination: 2.19% vs. 9.68%, χ2=8.85, P=0.01). There was no statistically significant difference in the long-term OHE incidence rate between the two kinds of treatment groups ( P>0.05). Conclusion:TIPS can significantly prolong transplant-free survival compared to standard treatment as a secondary prevention of EGVB concomitant with sarcopenia in patients with cirrhosis. However, its advantage is not prominent for patients with cirrhosis in EGVB without sarcopenia.

Objective:To summarize the clinical manifestations and diagnostic methods of adult neuronal intranuclear inclusion disease (NIID), improve understanding of the disease, and avoid misdiagnosis.Methods:Clinical data of 8 adult NIID patients in the Hunan region were collected, and their clinical manifestations, cranial imaging, genetic testing, skin biopsy, and other characteristics were analyzed.Results:Among the 8 patients, 4 were males and 4 were females; The initial symptoms of 2 patients were dizziness, 2 were mental abnormalities, 2 were stroke like attacks, 1 was urinary incontinence, and 1 was limb tremor; Six patients experienced slow progression of the disease, while two patients experienced sudden progression after several years of slow progression; The GGC repeat amplification mutation in the 5′untranslated region of the NOTCH2NLC gene, as well as the lace like sign in the brain cortex medullary junction on diffusion-weighted imaging (DWI) and the presence of eosinophilic transparent inclusion bodies in the nucleus on skin biopsy, were helpful in diagnosing NIID.Conclusions:The clinical manifestations of NIID are highly heterogeneous, and some patients have rare initial clinical symptoms, which are prone to misdiagnosis and missed diagnosis. It is necessary to combine imaging, genetic testing, and skin biopsy to confirm the diagnosis; Some patients may experience sudden progression and poor prognosis after years of slow progression.

Objective:To quantitatively analyze infection prevention and control policy texts related to medical alliance, aiming to provide reference for further policy improvement.Methods:with the " medical alliance" and " infection prevention and control" as keywords, relevant policy documents issued from January 2015 to March 2023 were searched on the Chinese government website, the official website of the National Health Commission, and the Peking University law database. Content analysis method was used to quantitatively analyze policy texts from two dimensions: policy tools (supply oriented, environmental oriented, demand oriented) and systems theory (management, service, human resources, and financing systems as internal subsystems, while political, economic, social, and technological systems as external subsystems).Results:A total of 91 infection prevention and control policy documents related to medical alliance were included, and 199 codes were obtained. There were 114, 78, and 7 codes for environmental oriented, supply oriented, and demand oriented policy tools, respectively; among the demand oriented tools, there were only 1 code for government purchases, 1 code for price subsidies, and 5 codes for demonstration project sub tools, respectively. The internal subsystem had a total of 119 codes, with only 2 codes related to the fundraising system; and the external subsystem had a total of 80 codes, with the least 10 codes related to the technical system.Conclusions:The structure of infection prevention and control policy tools in China′s medical alliance needed to be optimized, and the application of demand oriented policy tools was insufficient. It is necessary to strengthen the use of pull tools such as government purchases, price subsidies, and demonstration projects. At the same time, it is necessary to improve the construction of internal and external systems, especially in terms of fundraising and technology systems, to enhance the overall effectiveness of the medical alliance′s infection prevention and control system.

Objective:To explore the role of serum pyrrole-protein-adduct (PPA) in evaluating the severity and predicting the anticoagulant efficacy in patients with pyrrolidine alkaloid-related hepatic sinusoidal obstruction syndrome (PA-HSOS).Methods:From April 2018 to December 2019, the data of 48 patients with PA-HSOS admitted and treated at Drum Tower Hospital, Affiliated Medical College of Nangjing University were collected, which included PPA level, portal vein velocity (PVV), ascites grading, PA-HSOS severity grading (according to the new severity grading criteria for suspected hepatic sinusoidal obstruction syndrome in adults by the European Society of Blood and Bone Marrow Transplantation and adjusted) and the outcome of anticoagulation. Patients with acute onset (onset of symptoms within 1 month after consuming pyrrolizidine alkaloid-containing plants) were taken as research subjects. The combination of PPA with PVV or with ascites classification of PA-HSOS severity assessment model was fitted by logistic regression, and the logit values of 2 combination models were calculated, the formula was logit 1=0.034×PPA(nmol/L)+ 0.055×PVV(cm/s)-3.287, logit 2=0.039×PPA(nmol/L)-2.712×ascites grade 2 (Yes=1, No=0)-0.388×ascites grade 3 (Yes=1, No=0)-0.899. The patients received initial anticoagulation therapy at Drum Tower Hospital, Affiliated Medical College of Nanjing University were selected as research subjects. The anticoagulant efficacy prediction model of combination of PPA with serum creatinine (SCR) and with hepatic venous pressure gradient (HVPG) was fitted by logistic regression, and the logit value was calculated, the formula was logit 3=0.013×PPA(nmol/L)+ 0.064×SCR (mol/L)+ 0.542×HVPG (mmHg, 1 mmHg=0.133 kPa)-16.005. The predictive value of PPA in evaluating the severity of PA-HSOS and anticoagulant efficacy was evaluated. Receiver operating characteristic curve analysis was performed for statistical analysis. Results:The serum PPA level of 48 patients was 10.81 nmol/L (3.91 nmol/L, 32.04 nmol/L). Among them, 33 cases (68.8%) were mild PA-HSOS, 3 cases (6.2%) were moderate PA-HSOS, no severe PA-HSOS case and 12 cases (25.0%) were very severe PA-HSOS. Among 23 patients received initial anticoagulant therapy at Drum Tower Hospital, Affiliated Medical College of Nanjing University and with complete data, 8 patients responded and survived, and 15 patients did not respond (5 patients died, 1 patient relieved after continue anticoagulant therapy, and 9 patients survived after switching to anticoagulant therapy and transjugular intrahepatic portosystemic shunt (TIPS) treatment). One patient without initial anticoagulant therapy, survived after TIPS treatment because of the progress of the disease. Area under the curve (AUC) of PPA to assess the severity of acute onset PA-HSOS was 0.75, 95% confidence interval ( CI) was 0.52 to 0.98 ( P=0.047). When PPA≥45.519 nmol/L, the specificity and sensitivity in evaluating severe and very severe PA-HSOS was 100.0% and 57.1%, respectively. AUC of combination of PPA and PVV to assess the severity of PA-HSOS was 0.77, 95% CI was 0.55 to 1.00 ( P=0.032). When the logit of combination model≥0.180, the specificity and sensitivity in evaluating severe and very severe PA-HSOS was 71.4% and 81.8%, respectively. AUC of combination of PPA and ascites grade (grade 1, 2 or 3) to assess the severity of PA-HSOS was 0.85, 95% CI was 0.63 to 1.00 ( P=0.005). When the logit of combination model≥0.347, the specificity and sensitivity in evaluating severe and very severe PA-HSOS was 85.7% and 92.0%, respectively. AUC of combination of PPA, SCR and HVPG to predict anticoagulation efficacy was 0.85, 95% CI was 0.69 to 1.00 ( P=0.009). When the logit≥0.393, the specificity and sensitivity in predicting anticoagulation efficacy was 62.5% and 91.7%, respectively. Conclusions:PPA can be used to assess the severity of acute onset PA-HSOS patients, and combined with ascites grading can significantly improve its efficiency. PPA combined with SCR and HVPG can better predict anticoagulant efficacy.

Objective:The investigation and research on the application status of Hepatic Venous Pressure Gradient (HVPG) is very important to understand the real situation and future development of this technology in China.Methods:This study comprehensively investigated the basic situation of HVPG technology in China, including hospital distribution, hospital level, annual number of cases, catheters used, average cost, indications and existing problems.Results:According to the survey, there were 70 hospitals in China carrying out HVPG technology in 2021, distributed in 28 provinces (autonomous regions and municipalities directly under the central Government). A total of 4 398 cases of HVPG were performed in all the surveyed hospitals in 2021, of which 2 291 cases (52.1%) were tested by HVPG alone. The average cost of HVPG detection was (5 617.2±2 079.4) yuan. 96.3% of the teams completed HVPG detection with balloon method, and most of the teams used thrombectomy balloon catheter (80.3%).Conclusion:Through this investigation, the status of domestic clinical application of HVPG has been clarified, and it has been confirmed that many domestic medical institutions have mastered this technology, but it still needs to continue to promote and popularize HVPG technology in the future.

Objective:To summarize the clinical characteristics of adenovirus (HAdVs) pneumonia in children.Methods:The clinical manifestations, laboratory results, imaging features and treatment courses of 541 children with HAdVs pneumonia treated in Shenzhen Children′s Hospital from January 2017 to August 2019 were retrospectively studied.Results:The number of children diagnosed with HAdVs pneumonia increased year by year.A total of 541 patients were included in this study (214 females and 327 males, median age 31 months). The majority of patients (89.3%, 483/541 cases) were less than 6 years of age.Cough (98.3%, 532/541 cases) was the most common symptom, followed by fever (93.7%, 507/541 cases), tachypnea (36.6%, 198/541 cases) and wheeting (32.5%, 176/541 cases). Thirteen point three percent patients (72/541 cases) had existing primary diseases.Severe HAdVs pneumonia was observed in 33.8% of patients (183/541 cases), the most common intrapulmonary complication were pleural effusion(18.6%, 101/541 cases) and respiratory failure (7.0%, 38/541 cases). In co-infection cases, 46.9% of the patients (254/541 cases) suffered from co-infection with mycoplasma pneumoniae, 21.6% of the patients (117/541 cases) suffered from bacterial co-infection.Ninety-eight point five percent of the patients (533/541 cases) were cured, and 1.5% of the patients (8/541 cases) died or discharged voluntarily.Convulsions [ P=0.026, OR=7.312 (95% CI: 1.267-42.191)] and bacterial co-infections [ P=0.030, OR=2.724 (95% CI: 1.101-6.741)] were independently correlated with the occurrence of severe HAdVs pneumonia. Conclusions:Pre-school aged children are at higher risks of developing HAdVs pneumonia.The majority of patients presents with fever and cough as primary manifestations.Tachypnea and wheezing are also common clinical features of HAdVs pneumonia patients.Approximately a third of children with HAdVs pneumonia may develop into severe pneumonia.The presentation of convulsion and the exis-tence of bacterial co-infections may help to predict the development of severe HAdVs pneumonia in pediatric patients.

Psychological pain is a subjective experience, mainly from the psychological needs of frustration. It is characterized by the perception of negative changes in self and its functions, accompanied by strong negative emotions. Psychological pain is often associated with the decline of mental health, which is considered to be the core of the suicide process. A higher level of psychological pain is closely related to suicidal ideation and suicidal behavior. Therefore, the measurement and evaluation of psychological pain plays an important role in outpatient screening, clinical treatment and crisis intervention. In order to improve the recognition of psychological pain and the accuracy of suicide risk prediction, after more than 20 years of application and development, more than 10 methods of measuring psychological pain can be included in clinical risk assessment. The traditional assessment methods are mostly based on Shneidman ’s definition of psychological pain and suicide theory, which are used to measure the intensity and frequency of psychological pain. In recent years, the development of suicide model and theory provides a new perspective and theoretical basis for the assessment of psychological pain. The latest assessment methods tend to be shorter and more convenient, or present the specific clinical characteristics of psychological pain. In addition, thematic apperception test, visual analogue scale, pictorial representation of illness and self measure and structured interview make up for the limitations of self-report. In the future, the assessment can be further combined with neurobiology, mobile internet and other means, while considering the application in diverse environments such as special populations and cross-cultural groups.

Excessive theta (θ) frequency oscillation and synchronization in the basal ganglia (BG) has been reported in elderly parkinsonian patients and animal models of levodopa (L-dopa)-induced dyskinesia (LID), particularly the θ oscillation recorded during periods when L-dopa is withdrawn (the off L-dopa state). To gain insight into processes underlying this activity, we explored the relationship between primary motor cortex (M1) oscillatory activity and BG output in LID. We recorded local field potentials in the substantia nigra pars reticulata (SNr) and M1 of awake, inattentive resting rats before and after L-dopa priming in Sham control, Parkinson disease model, and LID model groups. We found that chronic L-dopa increased θ synchronization and information flow between the SNr and M1 in off L-dopa state LID rats, with a SNr-to-M1 flow directionality. Compared with the on state, θ oscillational activity (θ synchronization and information flow) during the off state were more closely associated with abnormal involuntary movements. Our findings indicate that θ oscillation in M1 may be consequent to abnormal synchronous discharges in the BG and support the notion that M1 θ oscillation may participate in the induction of dyskinesia.

OBJECTIVE: To evaluate the application value of 40 Hz auditory event related potential(40 Hz AERP) in hearing assessment in workers exposed to noise by observing the consistency between pure tone audiometry(PTA) and 40 Hz AERP. METHODS: A total of 240 ears of 120 workers who exposed to noise with PTA high-frequency hearing threshold > 25 dB were selected as the research subjects using the convenient sampling method. The thresholds of PTA and 40 Hz AERP at different frequencies were investigated. According to the average hearing threshold of PTA language frequency, the workers were divided into normal hearing group and mild-, medium-, medium-severe-, severe-hearing loss groups, and the difference and correlation between the thresholds of 40 Hz auditory potential and PTA were analyzed. RESULTS: The response thresholds of 40 Hz AERP of 0.5, 1.0, 2.0 kHz in ears of normal hearing group, and mild-and moderate-hearing loss groups were higher than the PTA hearing threshold(P<0.01), while the 40 Hz AERP response thresholds of 0.5 kHz in the ears of medium-severe-and severe-hearing loss groups were lower than the hearing thresholds of PTA(P<0.05). The different value of the response threshold of 40 Hz AERP and PTA of 1.0 and 2.0 kHz in ears of normal hearing group was higher than 0.5 kHz(median: 25.0 vs 15.0 dBHL, 30.0 vs 15.0 dBHL, P<0.01). Except for 0.5 and 1.0 kHz of mild-hearing loss group, the different value of the response threshold of 40 Hz AERP and PTA in ears of the other hearing loss groups were lower than that of the normal hearing group(P<0.01). The 40 Hz AERP response threshold was frequency-specific and correlated well with PTA at the same frequency. The correlation coefficients of 0.5, 1.0 and 2.0 kHz were 0.744, 0.732 and 0.665 respectively(P<0.01). CONCLUSION: It is feasible to evaluate PTA in noise-exposed workers using 40 Hz AERP response threshold, but the 40 Hz AERP cannot completely replace PTA. The measurement frequency and the degree of hearing loss should be considered simultaneously.
