Autonomic disturbances often occur in patients with acute cerebrovascular disease due to damage of the central autonomic network. We summarize the structures of the central autonomic network and the clinical tests used to evaluate the functions of the autonomic nervous system. We review the clinical and experimental findings as well as management strategies of post-stroke autonomic disturbances including electrocardiographic changes, cardiac arrhythmias, myocardial damage, thermoregulatory dysfunction, gastrointestinal dysfunction, urinary incontinence, sexual disorders, and hyperglycemia. The occurrence of autonomic disturbances has been associated with poor outcomes in stroke patients. Autonomic nervous system modulation appears to be an emerging therapeutic strategy for stroke management in addition to treatments for sensorimotor dysfunction.

BACKGROUNDThe traditional approach to blunt aortic injury (BAI) has been emergent intervention. This study aimed to utilize a modified imaging grading system that may allow us to categorize these injuries as needing emergent, urgent, or non-operative management.
METHODSFrom January 2003 to December 2011, 28 patients with BAI were managed at our institution. Imaging and medical records were reviewed retrospectively. BAI was classified into 4 grades based on imaging studies. Grade Ia: intimal tear, Grade Ib: intramural hematoma; Grade II: intimal injury with periaotic hematoma; Grade IIIa: aortic transection with pseudoaneurysm, Grade IIIb: multiple aortic injuries; and Grade IV: free rupture. Progression and clinical outcomes of ABI were analyzed.
RESULTSOf the 28 patients, 22 were males and 6 were females with mean age of 38 (range, 7 - 69) years. Twenty-five (89.3%) had descending thoracic aortic injury, two (7.1%) had abdominal aortic injury and one (3.6%) presented with multiple aortic injuries. Three patients (10.7%) with Grade I, 1 (3.6%) Grade II, 22 (78.6%) Grade III, and 2 (7.1%) Grade IV injuries. Twenty-five patients underwent thoracic endovascular aortic repair and 3 were managed medically. Median time between injury and surgical intervention was (2 ± 1) days. One (3.6%) patient developed paraplegia after thoracic endovascular aortic repair (TEVAR). One Type 2 endoleak spontaneously sealed within 1 month, and another patient died from ruptured Type 1 endoleak 3 years later. Median follow-up time was 16 (range, 1 - 96) months. Perioperative 30-day mortality rate was 3.6%.
CONCLUSIONSThis study based on our modified BAI grading system indicated that Grade I BAI can be managed conservatively. Grade II injury requires close observation and repeated computerized tomography angiogram (CTA) within 48 - 72 hours. If injury appears worse on follow up imaging, surgery should be performed. Delayed repair of Grade III BAI is acceptable if associated life threatening traumatic injuries need to be addressed first.

OBJECTIVETo investigate menopause-related symptoms, traditional Chinese Medicine (TCM)-diagnosis and hormone status of two comparable urban samples of menopausal women, one in Essen (Germany) and the other in Shanghai (China).
METHODSPatients suffering from menopause-syndrome were recruited from the TCM-outpatient clinic of the University of Duisburg-Essen in Germany (35 subjects) and from the Shuguang Hospital Affiliated to Shanghai University of Traditional Chinese Medicine in China (35 subjects). The Kupperman-Index for tracing menopausal symptoms was applied. The complete TCM-diagnosis was carried out by the same investigator in China as well as in Germany. Testosterone and estrogen blood samples were collected once from every woman.
RESULTSThere were significant differences in specific symptoms of the Kupperman-Index, such as a higher prevalence of formication and depression in German menopausal women; whereas Chinese menopausal women suffered significantly more from vertigo, headache and paraesthesia symptoms. Concerning TCM-diagnosis, Shen ()-yang deficiency was diagnosed in 51.43% of the German women in contrast to 5.71% of the Chinese women; 17.14% of the German women were diagnosed as having Shen-yin deficiency compared to 74.29% of the Chinese women. The German women showed significantly lower mean hormone levels for testosterone compared to the Chinese women (P CONCLUSIONSGerman and Chinese menopausal women do not show different prevalence but have different patterns of menopausal symptoms. Furthermore, from a TCM point of view, German women suffer more from Shen-yang deficiency whereas Chinese women suffer more from Shen-yin deficiency syndrome. These results are supported by significantly lower levels of testosterone in German women compared to Chinese women, which, in TCM, is a characteristic of yang deficiency.

OBJECTIVE:
Total ceramide concentrations are linked with increased insulin resistance and cardiac dysfunction. However, recent studies have demonstrated that plasma concentrations of specific very-long-chain fatty ceramides (C24:0 and C22:0) are associated with a reduced incidence of coronary heart disease and all-cause mortality. We hypothesized that specific genetic loci are associated with plasma C22:0 and C24:0 concentrations.
METHODS:
Heritability and genome-wide association studies of plasma C24:0 and C22:0 ceramide concentrations were performed among 2,217 participants in the Framingham Heart Study Offspring Cohort, adjusting for cardiovascular risk factor covariates and cardiovascular drug treatment.
RESULTS:
The multivariable-adjusted heritability for C22:0 and C24:0 ceramides was 0.42 (standard error [SE], 0.07; p=1.8E-9) and 0.25 (SE, 0.08; p=0.00025), respectively. Nineteen single nucleotide polymorphisms (SNPs), all on chromosome 20, significantly associated with C22:0 concentrations; the closest gene to these variants was SPTLC3. The lead SNP (rs4814175) significantly associated with 3% lower plasma C22:0 concentrations (p=2.83E-11). Nine SNPs, all on chromosome 20 and close to SPTLC3, were significantly associated with C24:0 ceramide concentrations. All 9 were also significantly related to plasma C22:0 levels. The lead SNP (rs168622) was significantly associated with 10% lower plasma C24:0 ceramide concentrations (p=9.94E-09).
CONCLUSION
SNPs near the SPTLC3 gene, which encodes serine palmitoyltransferase long chain base subunit 3 (SPTLC3; part of the enzyme that catalyzes the rate-limiting step of de novo sphingolipid synthesis) were associated with plasma C22:0 and C24:0 ceramide concentrations. These results are biologically plausible and suggest that SPTLC3 may be a potential therapeutic target for C24:0 and C22:0 ceramide modulation.

Objective:To explore the safety and efficacy of camrelizumab salvage therapy for extrahepatic recurrent hepatocellular carcinoma with PD-L1 negativity in transplanted liver tissue.Methods:From May 2020 to December 2020, retrospective analysis was performed for 3 cases of camrelizumab salvage therapy for extrahepatic recurrent hepatocellular carcinoma recipients with PD-L1 negative in transplanted liver tissue.Three recipients with extrahepatic recurrence progressed after first/second-line targeted drug therapy.Camrelizumab was given as salvage therapy after normal tissue of ransplanted liver was confirmed as negative for PD-L1 by immunohistochemistry.The safety and efficacy of treatment were observed by monitoring the changes in the levels of alanine aminotransferase, aspartate aminotransferase and bilirubin, the occurrence of complications and the outcome of treatment before and after dosing.Results:During a follow-up period of 1.5 to 15.5 months, no recipients showed acute rejection symptoms such as sharp elevations of transaminase and bilirubin.Headache ( n=1), vomiting ( n=1) and fatigue & hypertension ( n=1) became relieved after treatment.As of February 28, 2022, there were one survivor and two deaths.The fatal causes were tumor progression ( n=1) and thoracic aortic rupture due to esophageal perforation ( n=1). The survival time of recipients was (11-15.5) months and the progression-free survival time (4-6) months. Conclusions:For extrahepatic recurrent hepatocellular carcinoma with PD-L1-negative liver transplantation in normal liver tissue, camrelizumab salvage therapy can control tumor progression to a certain extent and prolong the survival time of recipients.

Case reports are valuable clinical evidence in traditional Chinese medicine (TCM). However, the general reporting quality is suboptimal. A working group comprising 20 members was set up to develop systematic recommendations on case report in Chinese medicine (CARC). The working group (CARC group) developed a primary checklist based on reviewing the general reporting quality of case reports in TCM and thorough internal discussion. Two-round consensus process had been carried out among clinical experts, evidence-based medicine methodologists, medical journal editors and clinical practitioners with designated questionnaire embedded with the primary checklist. In total, 118 participants from 17 provinces of China and Korea completed the questionnaires. Their feedback was analyzed and discussed by the CARC group. The checklist was amended accordingly, and the final version, comprising 16-item, is presented here. Under the framework of CARC recommendations, the reporting quality of case reports in TCM can be improved.

Objective:
To evaluate the efficacy and safety of ombitasvir/paritaprevir/ritonavir (OBV/PTV/r) 25/150/100 mg once daily and dasabuvir (DSV) 250 mg twice daily combined with ribavirin in adult patients of Mainland China with chronic HCV genotype 1b infection and compensated cirrhosis.
Methods:
An open-label, multicenter, phase 3 clinical trial study was conducted in mainland China, Taiwan, and South Korea. Adult patients with compensated cirrhosis (Metavir score =F4) who were newly diagnosed and treated for hepatitis C virus genotype 1b infection with ombitasvir/paritaprevir/ritonavir and dasabuvir combined with ribavirin for 12 weeks were included. Assessed SVR rate of patients obtained at 12 and 24 weeks after drug withdrawal. Efficacy and safety were evaluated in patients who received at least one time study drugs.
Results:
A total of 63 patients from mainland China were enrolled, 62 of whom (98.4%) had a baseline Child-Pugh score of 5 points. The overall rate of SVR12 and SVR24 in patients was 100% (95% CI: 94.3% to 100.0%). Most of the adverse events that occurred were mild. The incidence of common (≥10%) adverse events and laboratory abnormalities included elevated total bilirubin (36.5%), weakness (19.0%), elevated unconjugated bilirubin (19.0%) and conjugated bilirubin (17.5%), and anemia (14.3%). Three cases (4.8%) of patients experienced Grade ≥ 3 adverse events that were considered by the investigators to be unrelated to the study drug. None patients had adverse events leading to premature drug withdrawal.
Conclusion
Mainland Chinese patients with chronic HCV genotype 1b infection and compensated cirrhosis who were treated with OBV/PTV/r plus DSV combined with RBV for 12 weeks achieved 100 % SVR at 12 and 24 weeks after drug withdrawal. Tolerability and safety were good, and majority of adverse events were mild.
