Scavenger receptor class B, member 2 (SCARB2) is linked to Gaucher disease and Parkinson's disease. Deficiency in the SCARB2 gene causes progressive myoclonus epilepsy (PME), a rare group of inherited neurodegenerative diseases characterized by myoclonus. We found that Scarb2 deficiency in mice leads to age-dependent dietary lipid malabsorption, accompanied with vitamin E deficiency. Our investigation revealed that Scarb2 deficiency is associated with gut dysbiosis and an altered bile acid pool, leading to hyperactivation of FXR in intestine. Hyperactivation of FXR impairs epithelium renewal and lipid absorption. Patients with SCARB2 mutations have a severe reduction in their vitamin E levels and cannot absorb dietary vitamin E. Finally, inhibiting FXR or supplementing vitamin E ameliorates the neuromotor impairment and neuropathy in Scarb2 knockout mice. These data indicate that gastrointestinal dysfunction is associated with SCARB2 deficiency-related neurodegeneration, and SCARB2-associated neurodegeneration can be improved by addressing the nutrition deficits and gastrointestinal issues.

Objective Computational fluid dynamics software combined with finite element method was used to conduct 2D numerical simulation of pancreaticobiliary junction, and analyze the influence of biliopancreatic ampullary diaphragm, opening direction and shape of duodenal papilla on occult pancreaticobiliary reflux(OPBR). Methods The data of anatomical structure of pancreaticobiliary junction were obtained from online information. Pancreaticobiliary junction was reconstructed in 2D by computational fluid dynamics Fluent 2020R2 software. Different models were drawn for the pancreaticobiliary junction according to the following parameters: biliopancreatic ampullary diaphragm (with/without), opening direction of duodenal papilla(biased to the side of bile duct/central/biased to the side of pancreatic duct). A total of 6 models were used to analyze the risk factors for OPBR. Results When the anatomical structure of the biliopancreatic duct confluence was normal, that was, the ampullary diaphragm exists, no matter how the shape of the duodenal papilla and the opening direction changed, there was no pancreaticobiliary reflux. When the common channel was >5 mm due to the absence of the ampullary diaphragm and duodenal papilla was biased to the side of bile duct, a small amount of pancreatic juice refluxed into the lower end of the bile duct. When the common channel was >5 mm due to the absence of the ampullary diaphragm and duodenal papilla open position was in the middle of the biliopancreatic duct, the velocity and flow rate of pancreatic juice entering bile duct increased, and the degree of reflux was maintained at the lower end of the bile duct. When the common channel was >5 mm due to the absence of the ampullary diaphragm and the duodenal papilla was biased to the side of pancreatic duct, the degree of pancreaticobiliary reflux was more serious, and pancreatic juice reflux was observed throughout the entire bile duct. On the basis of this reflux model, the length of common channel of biliopancreatic duct was shortened, and the opening of outflow tract was enlarged, and the phenomenon of pancreaticobiliary reflux disappeared. Conclusions Based on the Fluent study, it is found that anatomical structures such as ampullary diaphragm and duodenal papilla were closely related to the occurrence of OPBR. Pancreaticobiliary reflux can be terminated by shortening the common channel length of pancreaticobiliary junction and expanding the opening of outflow tract.

OBJECTIVE:
To investigate the prevalence of comorbid depression and anxiety and to evaluate the effect of psychological interventions among schistosomiasis patients in China, so as to provide insights into improvements of psychological health among schistosomiasis patients.
METHODS:
Publications pertaining to comorbid depression and anxiety and psychological interventions among Chinese schistosomiasis patients were retrieved in electronic databases, including CNKI, Wanfang Data, PubMed, Web of Science, and Embase. The prevalence of comorbidity, psychological interventions, and scores for the Self-Rating Depression Scale (SDS) and Self-Rating Anxiety Scale (SAS) before and after psychological interventions among Chinese schistosomiasis patients were extracted. The prevalence of comorbid depression and anxiety was investigated among Chinese schistosomiasis patients using a meta-analysis, and the effect of psychological interventions for depression and anxiety was evaluated.
RESULTS:
A total of 231 publications were retrieved, and 14 publications that met the inclusion and exclusion criteria were included in the final analysis, including 2 English publications and 12 Chinese publications. Meta-analysis showed that the prevalence rates of comorbid depression and anxiety were 61% [95% confidential interval (CI): (48%, 72%)] and 64% [95% CI: (42%, 81%)] among Chinese schistosomiasis patients. Both the SDS [1.45 points, 95% CI: (1.30, 1.60) points] and SAS scores [2.21 points, 95% CI: (2.05, 2.38) points] reduced among Chinese schistosomiasis patients after psychological interventions than before psychological interventions, and the SDS [-0.47 points, 95% CI: (-6.90, -0.25) points] and SAS scores [-1.30 points, 95% CI: (-1.52, -1.09) points] reduced among Chinese schistosomiasis patients in the case group than in the control group.
CONCLUSIONS
The comorbid anxiety and depression are common among Chinese schistosomiasis patients, and conventional psychological interventions facilitate the improvements of anxiety and depression among schistosomiasis patients.

Blastocystis is a common unicellular intestinal protozoa in humans and animals, and the most common clinical manifestations of infections include abdominal pain and diarrhea. Based on the sequence of the small-subunit ribosomal RNA (SSU rRNA) gene, 28 subtypes of B. hominis (ST1 to ST17, ST21 and ST23 to ST32) have been characterized. Previous studies have demonstrated that B. hominis infection is strongly associated with inflammatory bowel disease (IBD), irritable bowel syndrome (IBS) and other intestinal diseases, which threatens the health and quality of life among patients with B. hominis infection and is considered as an important public health problem. This review summarizes the progress of researches on B. hominis infection among IBD and IBS patients during the past 20 years, so as to provide insights into management of blastocystosis in China.

Objective :
To investigate the factors affecting concurrent sarcopenia among patients with cardiovascular diseases, so as to provide insights into early identification and prevention of cardiovascular diseases complicated with sarcopenia.
Methods:
A total of 250 inpatients with cardiovascular diseases in the Sixth Division Hospital of Xinjiang Production and Construction Corps were recruited and divided into the sarcopenia and non-sarcopenia groups according to the diagnostic criteria of sarcopenia. Subjects' basic characteristics, body mass index, blood biochemical indicators and human body composition parameters were collected using questionnaire surveys, and factors affecting concurrent sarcopenia among patients with cardiovascular diseases using a multivariable logistic regression model.
Results:
Among the 250 patients with cardiovascular diseases, there were 149 males (59.60%) and 101 females (40.40%). The overall prevalence of sarcopenia was 8.40% among the study subjects. The mean age and body mass index were (75.19±9.74) and (20.77±2.19) kg/m2 in the sarcopenia group and (65.24±11.50) years and (25.85±2.87) kg/m2 in the non-sarcopenia group. Multivariable logistic regression analysis identified age (OR=1.115, 95%CI: 1.030-1.207) and body mass index (OR=0.582, 95%CI: 0.445-0.761) were as factors affecting concurrent sarcopenia among patients with cardiovascular diseases.
Conclusion
Advanced age and low body mass index may increase the risk of concurrent sarcopenia among patients with cardiovascular diseases.

Objective:
To evaluate the clinical efficacy of Compound Chamomile and Lidocaine Hydrochloride Gel for postoperative hypospadias in children.
METHODS:
From January to December 2020, we treated 116 children with distal hypospadias in the Department of Urology, Department of Pediatrics and the Seventh Medical Center of the PLA General Hospital, 58 by primary Snodgrass urethroplasty only (the control group) and the other 58 with Compound Chamomile and Lidocaine Hydrochloride Gel smeared on the penis postoperatively in addition (the trial group). We compared the operation time and postoperative pain score, edema regression and incidence of infection between the two groups, followed by statistical analysis using T test and Chi-square test.
RESULTS:
All the operations were successfully completed by the same surgeon under general anesthesia. There were no statistically significant differences between the trial and control groups in age ([2.5 ± 0.8] vs [2.4 ± 0.6] yr, P > 0.05) or operation time ([95.6 ± 14.5] vs [97.1 ± 15.2] min, P > 0.05). No incision infection occurred in any of the cases. The pain scores at dressing removal were remarkably lower in the trial than in the control group at 2 hours (1.4 ± 1.0 vs 2.6 ± 1.3, P < 0.05), 24 hours (2.2 ± 1.3 vs 3.9 ± 1.6, P < 0.05), 48 hours (1.2 ± 0.7 vs 1.6 ± 0.9, P < 0.05) and 72 hours after surgery (2.5 ± 0.8 vs 3.7 ± 1.8, P < 0.05). Significantly more cases of edema regression were achieved in the trial than in the control group at 2 weeks postoperatively (35 vs 19, P < 0.05).
CONCLUSIONS
Compound Chamomile and Lidocaine Hydrochloride Gel can effectively relieve pain, reduce edema and accelerate edema regression after surgery in children with hypospadias, and therefore deserves wide clinical application.、.

Parthenogenetic embryos, created by activation and diploidization of oocytes, arrest at mid-gestation for defective paternal imprints, which impair placental development. Also, viable offspring has not been obtained without genetic manipulation from parthenogenetic embryonic stem cells (pESCs) derived from parthenogenetic embryos, presumably attributable to their aberrant imprinting. We show that an unlimited number of oocytes can be derived from pESCs and produce healthy offspring. Moreover, normal expression of imprinted genes is found in the germ cells and the mice. pESCs exhibited imprinting consistent with exclusively maternal lineage, and higher X-chromosome activation compared to female ESCs derived from the same mouse genetic background. pESCs differentiated into primordial germ cell-like cells (PGCLCs) and formed oocytes following in vivo transplantation into kidney capsule that produced fertile pups and reconstituted ovarian endocrine function. The transcriptome and methylation of imprinted and X-linked genes in pESC-PGCLCs closely resembled those of in vivo produced PGCs, consistent with efficient reprogramming of methylation and genomic imprinting. These results demonstrate that amplification of germ cells through parthenogenesis faithfully maintains maternal imprinting, offering a promising route for deriving functional oocytes and having potential in rebuilding ovarian endocrine function.

The TEA domain (TEAD) family proteins (TEAD1‒4) are essential transcription factors that control cell differentiation and organ size in the Hippo pathway. Although the sequences and structures of TEAD family proteins are highly conserved, each TEAD isoform has unique physiological and pathological functions. Therefore, the development and discovery of subtype selective inhibitors for TEAD protein will provide important chemical probes for the TEAD-related function studies in development and diseases. Here, we identified a novel TEAD1/3 covalent inhibitor (DC-TEADin1072) with biochemical IC
