Hepatitis B (HB) is a globally prevalent infectious disease caused by the HB virus. Xiaochaihu decoction (XCHD) is a classic herbal formula with a long history of clinical application in treating HB. Although the anti-HB activity of XCHD has been reported, systematic research on the exact mechanism of action is lacking. Here, a network pharmacology-based approach was used to predict the active components, important targets, and potential mechanism of XCHD in HB treatment. Investigation included drug-likeness evaluation; absorption, distribution, metabolism, and elimination (ADME) screening; protein-protein interaction (PPI) network construction and cluster analysis; Gene Ontology (GO) analysis; and Kyoto Encyclopedia of Genes and Genomes (KEGG) annotation. Molecular docking was adopted to investigate the interaction between important target proteins and active components. Eighty-seven active components of XCHD and 155 anti-HB targets were selected for further analysis. The GO enrichment and similarity analysis results indicated that XCHD might perform similar or the same GO functions. Glycyrrhizae Radix (GR), one of the seven XCHD herbs, likely exerts some unique GO functions such as the regulation of interleukin-12 production, positive regulation of interleukin-1 beta secretion, and regulation of the I-kappaB/NF-kappaB complex. The PPI network and KEGG pathway analysis results showed that XCHD affects HB mainly through modulating pathways related to viral infection, immunity, cancer, signal transduction, and metabolism. Additionally, molecular docking verified that the active compounds (quercetin, chrysin, and capsaicin) could bind with the key targets. This work systematically explored the anti-HB mechanism of XCHD and provides a novel perspective for future pharmacological research.

To investigate the performance of a machine learning model based on a reduced dimensionality parameter space derived from complete Pentacam parameters to identify subclinical keratoconus (KC).

All 1692 available parameters were obtained from the Pentacam imaging machine on 145 subclinical KC and 122 control eyes. We applied a principal component analysis (PCA) to the complete Pentacam dataset to reduce its parameter dimensionality. Subsequently, we investigated machine learning performance of the random forest algorithm with increasing numbers of components to identify their optimal number for detecting subclinical KC from control eyes.

The dimensionality of the complete set of 1692 Pentacam parameters was reduced to 267 principal components using PCA. Subsequent selection of 15 of these principal components explained over 85% of the variance of the original Pentacam-derived parameters and input to train a random forest machine learning model to achieve the best accuracy of 98% in detecting subclinical KC eyes. The model established also reached a high sensitivity of 97% in identification of subclinical KC and a specificity of 98% in recognizing control eyes.

A random forest-based model trained using a modest number of components derived from a reduced dimensionality representation of complete Pentacam system parameters allowed for high accuracy of subclinical KC identification.

Some basic principles guide history-taking and observation in clinical epileptology. The information contained within subjective seizure descriptions can be framed within standardized vocabulary and a classification of ictal signs, seizure types, and the integrated framework of epilepsy syndromes. As illustrative examples, we discuss the historical origins and current research context of Dravet syndrome and Janz syndrome, two genetic epilepsy syndromes. In candidates for epilepsy surgery, ictal signs aid us in identifying the symptomatogenic zone and hence delineating the ictal onset zone. Here, historical reports from Victor Horsley and Hughlings Jackson provide valuable perspective on clinical reasoning. Lastly, the information contained within clinical signs and syndromes presents an indispensable data source in future efforts of large-scale genotype-phenotype correlations and machine learning methods.Salivary cortisol has been the central marker in psychoneuroendocrinological stress research for three decades. Given the technological possibilities to assess data in ecologically valid circumstances, many studies have implemented longitudinal assessments of salivary cortisol in study participants' everyday life. Such studies bear the potential to understand real-life associations of cortisol with psychological traits, states, and health variables.

While standardized paradigms have been developed to measure cortisol in laboratory settings, there is high heterogeneity in the assessment, statistical processing, and interpretation of everyday life cortisol measures. This methodological tutorial aims at summarizing important knowledge which had been accumulated during the past two decades and which could be used to set up an ambulatory assessment study focusing on salivary cortisol in everyday life. Practical advice for possible strategies at all stages of the research process is outlined in detail. Additionally, an example on how to statistically process cortisol data in a multilevel framework (including syntax) is provided. In these analyses, we investigate within- and between-person research questions regarding the association between stress and cortisol in daily life. Thus, the present work (a) can be used as tutorial for setting up everyday life studies focusing on the assessment of salivary cortisol, and (b) can be useful to avoid inconsistencies in study planning, data assessment and data processing in future studies.The menopause transition, which constitutes the five or so years surrounding the final menstrual period, has been established as a time of increased risk for depressive symptoms. While mounting research suggests that exposure to more extreme and fluctuating levels of estradiol (E2) plays a role, it remains unclear which specific trigger is most strongly implicated in the development of depressive mood acute E2 withdrawal or extreme increases in E2. The current review summarises the literature supporting the role of each, considering research pertaining to perimenopausal depression as well as other reproductive mood disorders in which ovarian hormone change is believed to play a key role, namely premenstrual dysphoric disorder and postpartum depression. Taking together the available research pertaining to the various reproductive mood disorders, we propose that women may exhibit one of four E2 sensitivity profiles, each of which may have important implications for the expected timing and severity of depressive mood during the menopause transition the E2-increase sensitive profile, developing depressive mood in response to elevations in E2, the E2-decrease sensitive profile, for whom E2 withdrawal triggers negative mood, the E2-change sensitive profile, characterised by mood sensitivity to E2 change in either direction, and the E2 insensitive profile for whom changes in E2 have negligible psychological effects. The evidence supporting the existence of such profiles are summarised, potential biological mechanisms are briefly highlighted, and implications for future research are discussed.

Popliteal artery thrombosis a rare but life-threatening complication of Paroxysmal Nocturnal Hemoglobinuria caused due to hemolysis. Complications of further thrombotic event are common after initial management.

A 38years old male, known case of PNH for 2years, presented with the history of loss of pain sensation, coldness and loss of movement in left lower leg for 5days and history of multiple blood transfusion. The patient underwent knee amputation because of possible complication of PNH.

Intermittent claudication along with paresthesia, lower extremity weakness, stiffness, and cool extremities are seen in patients of Peripheral Artery Disease. Ultrasound color duplex is a sensitive and specific examination for peripheral flow while gold standard techniques like MRI and CT angiogram to detect and diagnose arterial lesions.

The risk of thrombo-embolism in a patient of PNH should be considered by a treating doctor while early imaging and management should be done to reduce the complications and risk of amputation.

Spinal intramedullary dermoid is very rare, accounting for <1% of intraspinal tumors. It can be congenital or acquired. They usually present in 2nd or 3rd decade of life in adults. It may or may not associated with spinal dysraphism. It is asymptomatic in most cases, manifest acutely if it ruptures. Long segment involvement of spinal intramedullary tumor in adult without the history of trauma makes this case unique. Fat suppression imaging helps to distinguish adipose tissue from lesions causing hematomyelia in patients presented with intramedullary hyperintensity in both T1 & T2 sequences of MRI spine.

We report here a rare case of 30years old male who presented to us with sudden urinary retention followed by rapidly progressive quadriparesis and paresthesia in his right arm. In MRI, spinal intramedullary tumor was noted from medulla till D5 vertebra. We performed subtotal excision of tumor and sample sent for histopathology which proved it to be intramedullary spinal dermoid cyst.

Long segment involvement of spinal intramedullary dermoid cyst in adult without history of trauma makes this case different. Fat suppression imaging must be done in patients with intramedullary hyperintensity in both T1 and T2 sequences of MRI spine. Early diagnosis and appropriate management will be helpful in reducing morbidity.

Craniofacial Tessier Cleft type 3 as a common craniofacial cleft with nasolabial region soft tissue defect, forced surgeons to find their ways of reconstructing using localregional flaps to provide defect closure. The cleft may occur in existence with other constriction band syndrome entity such as the ADAM complex. The effort to repair and give back the basic function for daily activity, put surgeons to find ways and one among them are soft tissue reconstruction using most reliable are forehead and melolabial flaps. However, many cases may limit their usages.

A four-month-old boy presented with ADAM complex syndrome with bilateral facial cleft Tessier 3 was done soft tissue reconstruction to repair the bilateral cleft lips using a combination of the paranasal flap. No early treatment approach such as molding was used. Although the cleft was wide enough, with limitation in flap modality, the wound healing was remarkable with no dehiscence.

This patient nasal/glabellar flap was not feasible due to glabellar region defect.
