Objective To explore the effects of Shaoyao Gancao granule on hair growth,behavior,and the hypothalamic pituitary adrenal(HPA)axis in mice with alopecia areata(AA).Methods Forty-two C3H/HeJ mice were randomly divided into control,model,Shaoyao Gancao granule high-,middle-,low-dose,corticotropin-releasing hormone receptor 1(CRHR1)antagonist,and compound glycyrrhizin tablet(CGT)groups.Photography,dermoscopy,weight analysis,and behavioral measurement were performed.Corticotropin-releasing hormone(CRH),adrenocorticotropic hormone(ACTH),cortisol,glucocorticoid receptor(GR),and brain-derived neurotrophic factor(BDNF)were also assessed.Results Compared with the model group,high-dose Shaoyao Gancao granules improve hair regeneration and weight gain(P＜0.05),increased the percentage of total exercise distance and central area exercise distance in an open field test(P＜0.05),reduced the immobility time in the forced swimming and tail suspension experiments(P＜0.05),reduced peripheral blood levels of CRH,ACTH,and cortisol(P＜0.05),and increased expression of GR and BDNF in the hippocampus(P＜0.05).Conclusions Shaoyao Gancao granule promotes hair growth and improves behavioral performance in mice with AA.These effects may be related to downregulating CRH,ACTH,and cortisol expression,upregulating GR and BDNF expression,and inhibiting excessive activation of the HPA axis.

Small cell lung cancer （SCLC） accounts for about 15% in lung cancer and is highly malignant， heterogeneous and invasive. Etoposide combined with platinum-based chemotherapy is the basis of standard first-line treatment for extensive-stage SCLC， but suffers from the problem of susceptibility to drug resistance and relapse. In recent years， the emergence of new immunological drugs and novel cytotoxic drugs has improved the survival of SCLC patients to a certain extent， especially bringing therapeutic hope to patients with relapsed/refractory SCLC. In this paper， we review the current clinical drug regimens and the new progress of potential target drug therapeutic regimens for the treatment of SCLC. At present， the first-， second- and third-line schemes of SCLC include etoposide+carboplatin， atezolizumab+etoposide+platinum， adebrelimab， topotecan， docetaxel， etc.； the current drug targets for the treatment of SCLC mainly focus on topoisomerase Ⅱ/Ⅰ， DNA， the immune checkpoint molecules programmed death-1/programmed death-ligand 1， tubulin， etc. The potential target drug therapeutic options include alisertib+ paclitaxel， rovalpituzumab， APG-1252， etc.， and mainly focus on DNA damage response pathways and immune pathways， which can achieve the prolongation of patient survival by exerting anti-tumor effects through aurora kinase A and other potential targets.

Lipid homeostasis is considered to be related to intestinal metabolic balance, while its role in the pathogenesis and treatment of ulcerative colitis (UC) remains largely unexplored. The present study aimed to identify the target lipids related to the occurrence, development and treatment of UC by comparing the lipidomics of UC patients, mice and colonic organoids with the corresponding healthy controls. Here, multi-dimensional lipidomics based on LC-QTOF/MS, LC-MS/MS and iMScope systems were constructed and used to decipher the alteration of lipidomic profiles. The results indicated that UC patients and mice were often accompanied by dysregulation of lipid homeostasis, in which triglycerides and phosphatidylcholines were significantly reduced. Notably, phosphatidylcholine 34:1 (PC34:1) was characterized by high abundance and closely correlation with UC disease. Our results also revealed that down-regulation of PC synthase PCYT1α and Pemt caused by UC modeling was the main factor leading to the reduction of PC34:1, and exogenous PC34:1 could greatly enhance the fumarate level via inhibiting the transformation of glutamate to N-acetylglutamate, thus exerting an anti-UC effect. Collectively, our study not only supplies common technologies and strategies for exploring lipid metabolism in mammals, but also provides opportunities for the discovery of therapeutic agents and biomarkers of UC.

Objective:To evaluate the clinical efficacy of C-type endoscopic submucosal dissection (C-ESD) for rectal neuroendocrine tumors (NEN).Methods:The retrospective analysis was performed on data of 55 patients who underwent ESD for rectal NEN at the Department of Endoscopy in Quanzhou First Hospital from January 2018 to July 2021. Patients were divided into the C-ESD group ( n=28) and the conventional ESD group ( n=27). The dissection time, the dissection speed, the number of submucosal injections, the enbloc resection rate, the curative resection rate and the rate of postoperative complications of the two groups were compared. Results:There were no statistically significant differences in basic information between the two groups ( P>0.05). The dissection time was 13.8±4.2 min in the C-ESD group and 19.9±3.9 min in the conventional ESD group with statistically significant difference ( t=5.649, P<0.001). The dissection speed in the C-ESD group was 0.08±0.04 cm 2/min, which was faster than 0.06±0.04 cm 2/min in the conventional ESD group ( t=2.218, P=0.031). The number of submucosal injections in the C-ESD group was less than that in the conventional ESD group [2 (1, 2) VS 3 (2, 3), Z=-8.701, P<0.001]. The lesions were enbloc resected in both groups. The curative resection rate in the C-ESD group was 100.0% (28/28) and 88.9% (24/27) in the conventional ESD group with statistically significant difference ( P=0.011). There were 7 cases of postoperative complications in the conventional ESD group, including 1 delayed bleeding, 5 delayed perforation and 1 muscularis propria injury, while no postoperative complications occurred in the C-ESD group ( P=0.004). Conclusion:C-ESD is a safe and effective treatment strategy for colorectal NEN, which can shorten the dissection time, improve the dissection speed, reduce the number of submucosal injections, improve the curative resection rate, and reduce complications.

ObjectiveTo analyze the quality of life and related factors in patients with depression， and to provide evidence for formulating the corresponding measures to improve the patients' quality of life. MethodsA total of 117 inpatients who met the International Classification of Diseases， tenth edition（ICD-10） for depression were selected in Central People's Hospital of Zhanjiang， Affiliated Hospital of Guangdong Medical University and Guangdong 999 Brain Hospital from November 19， 2018 to September 7， 2019. The values of patients' clinical objective indicators consisted of routine blood test， routine urine examination， blood biochemical tests and blood gas analysis were collected by reviewing their medical records， and all subjects were assessed using Quality of Life Instruments for Chronic Diseases-Depression V2.0 ［QLICD-DE（V2.0）］. Simple correlation analysis was used to explore the correlation between the QLICD-DE （V2.0） scores and various clinical objective indicators， and multiple linear regression was adopted to further screen factors affecting quality of life of patients with depression. ResultsSimple correlation analysis suggested that QLICD-DE （V2.0） total score was positively correlated with total protein and platelet distribution width in patients with depression （r=0.198， 0.281， P<0.05 or 0.01）， and negatively correlated with hematocrit （r=-0.300， P<0.01）. Multiple linear regression analysis showed that albumin-to-globulin ratio and treatment compliance （B=-19.836， -3.711， P<0.05 or 0.01） were influential factors for physical function. Platelet distribution width （B=2.706， P<0.01） was an influential factor for psychological function. Bilirubin （B=-6.375， P<0.05） was an influential factor for social function. Platelet distribution width （B=2.101， P<0.05） was an influencing factor for specific module. The albumin-to-globulin ratio and platelet distribution width （B=-10.653， 2.114， P<0.05 or 0.01） were influencing factors for total score of QLICD-DE （V2.0）. ConclusionTreatment compliance and clinical objective indicators platelet distribution width， bilirubin and albumin-to-globulin ratio may be the influencing factors of quality of life in patients with depression.

【Objective】 To explore the application value of preoperative gastroscopic carbon nanoparticles labeling in patients undergoing laparoscopic radical gastric cancer surgery. 【Methods】 We included cases of laparoscopic radical gastric cancer surgery at The First Affiliated Hospital of Xi’an Jiaotong University from January 2017 to December 2019. Some cases received submucosal injection of carbon nanoparticles under the gastroscope before surgery. The effects of carbon nanoparticles labeling on the number of lymph nodes detected， operation duration and surgical complications were compared and analyzed. 【Results】 A total of 397 patients undergoing laparoscopic radical gastric cancer surgery were enrolled. Among them， 78 cases underwent gastroscopic carbon nanoparticles tracer labeling before operation. No complications were observed. The total number of lymph nodes detected by pathology after surgery in the carbon nanoparticles group significantly increased ［（22.0（4.0） vs. 22.0（3.0）， P=0.033）］ while the operation time significantly reduced ［（185.0±37.48）min vs. （213.4±23.66）min， P<0.001］ compared with those in the control group. New gastric cancer lesions were revealed by gastroscopy in three cases （3.8%） of carbon nanoparticles labeling， and the original planned operation method was changed in two cases （2.6%）. 【Conclusion】 Preoperative endoscopic carbon nanoparticles tracer labeling can not only help shorten the time of laparoscopic radical surgery for gastric cancer and increase the number of total lymph nodes detected for more accurate TNM staging， but also provide an opportunity for the discovery of synchronous multiple gastric cancer.

Objective:To analyze the clinical characteristics of neonatal enteroviral meningitis.Methods:A retrospective analysis was conducted on 87 cases with intracranical infection.The cerebrospinal fluid(CSF)samples of these neonates were collected and tested by polymerase chain reaction(PCR) for enterovirus.According to the results, the cases were divided into the positive group(55 cases) and negative group(32 cases). The clinical characteristics of the cases were collected.Results:The time in hospital of the positive group was shorter than the negative group[(9.5±5.2)d vs.(21.8±15.8)d, t=4.295, P<0.001]. The cure rates of the positive group was higher[96.4%(53/55) vs. 81.2%(26/32), χ2=3.872, P=0.049]. There was no death case in the positive group, while there were 3 death cases(9.4%, 3/32)in the negative group.In summer and autumn, the morbidity of the positive group was higher[96.4%(53/55) vs.62.5%(20/32), χ2=17.181, P<0.001]. In two groups, the most predominant clinical presentation was fever[90.9%(50/55) vs. 68.8%(22/32), χ2=6.962, P=0.008]. CSF examination results showed that white blood cells, the proportion of polymorphonuclear cell and CSF protein in the positive group were lower than those in the negative group, while the proportion of mononuclear cell and CSF glucose level in the positive group were higher( P<0.001). Blood and CSF cultures were negative in the positive group.There were 10 cases whose blood cultures and CSF cultures were positive in the negative group.Among them, there were 3 cases infected by group B streptococcus, 6 cases by E. coli, 1 case by Chryseobacterium meningosepticum.The prognoses of the CSF culture positive cases were poor.The abonormal cases detected by cerebral ultrasound, MRI and aEEG were fewer in the positive group( P<0.05). Conclusion:Enterovirus is the common pathogen of nonbacterial meningitis in summer and autumn in our region.The prognosis of enteroviral meningitis is better.Neonates with suspected clinical presentation, such as fever, should undergo PCR test to check CSF for enteroviru.

Objective: To investigate fusidic acid resistance in Staphylococcus aureus (S.aureus) strains and to analyze their molecular characteristics. Methods: A total of 1 333 strains of S. aureus isolated in the First Affiliated Hospital of Wenzhou Medical University from October 2013 to March 2016 were collected. Fusidic acid resistance in these strains was detected by K-B method. Minimum inhibitory concentrations (MIC) of fusidic acid were measured by agar dilution method. Resistance genes of fusB, fusC and fusD and S. aureus A protein-coding gene (spa) were detected by PCR. Strains that did not carry fusB, fusC or fusD were detected for mutations in fusA by sequencing. Housekeeping genes were detected by PCR and analyzed by multilocus sequence typing (MLST). Results: Among the 1 333 strains of S. aureus, 52 were resistant to fusidic acid, accounting for 3.90%. From 2013 to 2016, fusidic acid-resistant strains accounted for 5.3% (7/132), 3.5% (20/571), 4.1% (21/510) and 3.3% (4/120), respectively. The MIC values of fusidic acid against S. aureus were 2, 4, 8, 64 and >64 μg/ml, which inhibited the growth of 26.9% (14/52), 34.6% (18/52), 13.5% (7/52), 1.9% (1/52) and 23.1% (12/52) of strains, respectively. MLST revealed that there were 13 sequence types (STs), among which ST630 was the predominant type accounting for 50% (26/52), followed by ST5 accounting for 17.3% (9/52). There were 19 spa types, among which t4549 (11/52), t2460 (8/52), t377 (8/52) were the predominant types. Nine strains carried drug resistance genes accounting for 17.3% (9/52), including seven fusB-positive and two fusD-positive strains. No fusc-positive strains were detected. Mutations in fusA gene were detected in 11 strains (21.2%, 11/52) and the MIC values against them were all >64 μg/ml. The predominant type of the strains with fusA gene mutations was ST5-t2460. Conclusion Fusidic acid shows a good and relatively stable in vitro antibacterial activity against S. aureus. The mechanism of high resistance to fusidic acid is closely related to fusA gene mutation.

Objective To explore the application of plastic pancreatic stents and/or nasal biliary drainage for choledocholithiasis patients having DSBC during Endoscopic Retrograde Cholangiopancreatography (ERCP).Methods Retrospective analysis on clinical data of 57 ERCP cases aiming at choledocholithiasis patients having DSBC from January 2010 to December 2015 has been carried out. According to the guide wire cannulation in an operation, patients are divided into three groups, i.e. plastic pancreatic stents group, nasal biliary drainage group, and plastic pancreatic stents + nasal biliary drainage group, so as to observe the success rate of operation and the occurrence rate of postoperative complications, such as pancreatitis or hyperamylasemia, as well as to compare the differences between the three groups.Results Out of the 57 patients receiving ERCP, 13 patients are in the plastic pancreatic stents group, with two successful operations (15.4%), one case of hyperamylasemia (7.7%), two cases of postoperative pancreatitis (15.4%), one case of fever (7.7%) and one case of hemorrhage (7.7%); 20 patients are in the nasal biliary drainage group, with 20 successful operations (100.0%), no occurrence of hyperamylasemia or postoperative pancreatitis or other complications including hemorrhage and fever; 24 patients are in the plastic pancreatic stents + nasal biliary drainage group, with 19 ERCP operations succeeded at the first attempt (79.2%) and 5 ERCP operations succeeded at the second try (20.8%), as well as 4 cases of hyperamylasemia (16.7%), 2 cases of hemorrhage (8.3%) , no occurrence of fever cases and postoperative pancreatitis. In comparison between the three groups, the occurrence of postoperative pancreatitis and successful rate of operation show a significant difference.Conclusion By adopting plastic pancreatic stents and/or nasal biliary drainage for patients having a dififcult selective biliary cannulation during ERCP, the success rate of operation can be improved, and the occurrence of pancreatitis can also be reduced.
