RESUMEN
BACKGROUND: Acne vulgaris is a prevalent skin condition. We have found that some acromegaly patients have acne. However, no study has examined the relationship between acromegaly and acne. OBJECTIVE: To explore prevalence and correlation of adult acne in patients with acromegaly. METHODS: For this cross-sectional study, we collected questionnaires, clinical information, and laboratory test results of acromegaly patients from January 2022 to December 2022 at Huashan Hospital. Of the 133 questionnaires returned, 123 had valid responses. RESULTS: Of the 123 patients with acromegaly enrolled in this study, 54.5% had adult acne. No statistically significant difference was found in prevalence between male and female patients. 61.2% of adult acne patients reported late-onset acne. Late-onset acne patients first developed acne years before acromegaly diagnosis (mean of 5.6 years for male and 4.5 years for female patients). Some acne patients have received traditional anti-acne treatment. Moreover, 31% of the patients reported no improvement, and only 3.5% of patients claimed complete resolution of acne after treatment. Before acromegaly treatment, the prevalence of adult acne was 51.2%, with mild acne accounting for 73.0%, moderate acne accounting for 23.8%, and severe acne accounting for 3.2%. After acromegaly treatment, the prevalence of adult acne was significantly decreased to 37.4% (P = 0.007). An overall decrease in acne severity was noted, with 93.5%, 6.5%, and 0% having mild, moderate, and severe acne, respectively. A total of 83.6% of the patients had self-assessed acne remission, and 33.3% of the patients reported complete acne resolution. However, 9.0% of patients reported that their condition had worsened after acromegaly treatment. After treatment, GH, IGF-1, IGF-1 index, insulin levels, and HOMA-IR decreased significantly in all patients with acromegaly (P < 0.05). Acne remission correlated positively with IGF-1 levels, but not with GH levels. The relationship between acromegaly and acne remains to be elucidated. CONCLUSIONS: Our findings provide preliminary evidence of the high prevalence of adult acne in acromegaly patients, and a high rate of late-onset acne as well. Traditional anti-acne treatments are less effective. Acne could be considerably relieved by treating acromegaly. Acne remission positively correlated with IGF-1 decline as well, which revealed the correlation between acne and IGF-1.

MET gene is a proto-oncogene, which encodes MET protein with tyrosine kinase activity. After binding to its ligand, hepatocyte growth factor, MET protein can induce MET dimerization and activate downstream signaling pathways, which plays a crucial role in tumor formation and metastasis. Savolitinib, as a specific tyrosine kinase inhibitor (TKI) targeting MET, selectively inhibits the phosphorylation of MET kinase with a significant inhibitory effect on tumors with MET abnormalities. Based on its significant efficacy shown in the registration studies, savolitinib was approved for marketing in China on June 22, 2021 for the treatment of advanced non-small cell lung cancer with MET 14 exon skipping mutations. In addition, many studies have shown that MET TKIs are equally effective in patients with advanced solid tumors with MET gene amplification or MET protein overexpression, and relevant registration clinical studies are ongoing. The most common adverse reactions during treatment with savolitinib include nausea, vomiting, peripheral edema, pyrexia, and hepatotoxicity. Based on two rounds of extensive nationwide investigations to guide clinicians, the consensus is compiled to use savolitinib rationally, prevent and treat various adverse reactions scientifically, and improve the clinical benefits and quality of life of patients. This consensus was prepared under the guidance of multidisciplinary experts, especially including the whole-process participation and valuable suggestions of experts in Traditional Chinese Medicine, thus reflecting the clinical treatment concept of integrated Chinese and western medicines.

OBJECTIVE: To investigate the clinicopathological features and prognosis of fumarate hydratase deficient renal cell carcinoma (FH-RCC). METHODS: Immunohistochemical (IHC) staining was used to detect the expression of fumarate hydratase (FH) in tumor tissues of 109 different types of renal cell carcinoma (RCC) patients aged 60 years and younger from the Department of Urology of Peking University First Hospital from January 2013 to December 2019. The clinicopathological data and prognosis of FH-RCC were collected and analyzed. RESULTS: There were eleven patients with FH-negative expression. Seven were males and four females. The age of onset ranged 16-53 years (mean age: 36.7 years), and four female patients all had a history of uterine leiomyoma. Only one first-degree relative of one patient had renal cancer, and none of the patients had a history or family history of cutaneous leiomyomas. The diameter of the tumor was 2.1-12.0 cm (mean: 8.83 cm). Renal sinus or perirenal fat invasion was seen in nine cases, tumor thrombus in renal vein or inferior vena cava in six cases, lymph node metastasis in seven cases, adrenal gland invasion in four cases and splenic capsule invasion in one case. The cases were initially diagnosed as type â ¡ papillary RCC (7/49, 14.3%), collecting duct carcinoma (2/9, 22.2%) and unclassified RCC (2/51, 3.9%). Tumor histopathology mostly showed a mixture of different structures, such as papillary, tubular cystic, solid, and so on. The most common histological structures were papillary (9/11, 81.8%) and tubular (8/11, 72.7%). Three cases had sarcomatoid areas. At least focal eosinophilic nucleolus (WHO/grades â ¢-â £) and perinuclear halo could be seen in all cases. Immunohistochemical (IHC) stains of most tumors were negative for CA9, CD10 and CK7. The results of fluorescence in situ hybridization (FISH) showed that there was no translocation or amplification of TFE3 gene in two cases with TFE3 IHC expression. All the patients were followed up for 11-82 months. Mean survival was 24 months. Five cases died of distant metastasis 9-31 months after operation (mean: 19 months), and five of the six patients alive had became metastatic. CONCLUSION: Morphologically, FH-RCC overlaps with many types cell RCC. A mixture of papillary and tubular cystic arrangement is the most common growth pattern of FH-RCC. At least focally large and obvious eosinophilic nucleoli are an important histological feature of this tumor. The negative expression of FH can help to confirm the diagnosis. Young female RCC patients with uterine leiomyomas should be suspected of FH-RCC. Some FH-RCC cases lack clinical evidence. The suspicion raised by pathologists based on histological characteristics is often the key step to further genetic testing and the final diagnosis of the tumor.

Based on Yichang health big data platform, 850 608 patients from September 2018 to September 2019 were included in this study. According to the date of birth, the participants were divided into early childhood famine exposure group, fetal famine exposure group and non-famine exposure group. The incidence of adult herpes zoster (HZ) in Yichang city was analyzed, and the correlation between early life famine exposure and adult HZ was analyzed. In 2019, the crude incidence rate of adult HZ in Yichang was 6.83. The crude incidence rate of adult HZ in females (7.26) was higher than that in males (6.40). Compared with the non-famine exposure group, fetal famine exposure was associated with the incidence of adult HZ (OR=1.21; 95%CI: 1.01-1.45, P=0.041). After stratification by sex, fetal famine exposure was only found to be associated with the onset of adult HZ in females (OR=1.28, 95%CI:1.02-1.61, P=0.034).

Objective: To explore the predictive value of complement and coagulation indicators in sepsis related acute kidney injury (AKI). Methods: Clinical data of 217 patients with sepsis admitted to the Department of Internal Medicine and Intensive Care Unit of Affiliated Hospital of Jiangnan University from January 2018 to June 2019 were retrospectively analyzed. All patients were divided into sepsis with AKI group and without AKI group. Laboratory indicators of all patients were collected, including complement C3, complement C4, activated partial thrombin time (APTT), prothrombin time (PT), international normalized ratio (INR), D-dimer, procalcitonin(PCT), etc. logistic regression analysis was used to explore the risk factors of sepsis related AKI. Receiver operating characteristic curve (ROC) was used to evaluate the predictive value of independent risk factors. Results: Among 217 patients, 120 patients developed sepsis related AKI and 97 patients didn't. PCT, lactic acid, PT, APTT, INR and D-dimer in AKI patients were significantly higher than those without AKI (P<0.01). Complement C3 and complement C4 were significantly lower in AKI group (P<0.01). Multivariate logistic regression analysis suggested that blood pressure<90/60 mmHg (1 mmHg=0.133 kPa)(OR=3.705, 95%CI 1.536-8.934,P=0.004), increased lactic acid (OR=1.479, 95%CI 1.089-2.008, P=0.012), decreased complement C3 (OR=0.027, 95%CI 0.005-0.152, P<0.001) and prolonged APTT (OR=1.090, 95%CI 1.047-1.137,P<0.001)were independent risk factors predicting AKI. The area under the ROC curve (AUC) of these multivariates were 0.741 (95%CI 0.675-0.807), 0.798 (95%CI 0.732-0.864), 0.712 (95%CI 0.643-0.781) and 0.716 (95%CI 0.648-0.783) respectively. The relevant sensitivity was 57.5%, 80.8%, 87.5%, 59.2%, and the specificity was 90.7%, 75.3%, 51.5%, 77.3%, respectively. The AUC of the combined four indicators was 0.880 (95%CI 0.835-0.926) with the sensitivity 75.0% and the specificity 90.7%. Conclusion: The low level of complement C3 and prolonged APTT predict sepsis related AKI, and the predictive value can be enhanced if hypotension and hyperlactacidemia are added.

Liver transplantation is currently the only effective treatment for end-stage liver disease. The preservation of donor liver before transplantation is important. But both traditional static cold storage and machine perfusion are limited by the preservation time, so that the allotment space of donor liver is limited, which inevitably leads to the abandonment of part of donor liver.At present, to find a preservation technology that not only guarantees the quality of donor liver but also has a longer effective preservation time is the direction of joint efforts of all clinicians. Supercooling liver preservation(SLP) to find a preservation technology that not only guarantees the quality of donor liver but also has a longer effective preservation time is the direction of joint efforts of all clinicians. SLP, a new method based on using cryoprotectants to keep donor liver under -6 â and recovering the graft with subnormothermic machine perfusion that enables long-term transplantation survival following 4 days of liver preservation, made a revolutionary breakthrough in the field of liver preservation, carved out a new field for the research of liver preservation. This article reviews the latest experimental research progress of SLP in the field of liver transplantation.

Achieving efficient localization of white light at the nanoscale is a major challenge due to the diffraction limit, and nanoscale emitters generating light with a broadband spectrum require complicated engineering. Here we suggest a simple, yet highly efficient, nanoscale white-light source based on a hybrid Si/Au nanoparticle with ultrabroadband (1.3-3.4 eV) spectral characteristics. We incorporate this novel source into a scanning-probe microscope and observe broadband spectrum of photoluminescence that allows fast mapping of local optical response of advanced nanophotonic structures with submicron resolution, thus realizing ultrabroadband near-field nanospectroscopy.
RESUMEN
PURPOSE: To investigate the efficacy and safety of doublet versus single-agent chemotherapy (CT) plus trastuzumab (H) as first-line therapy for human epidermal growth factor 2 receptor (HER2)-positive metastatic breast cancer (MBC). METHODS: We searched for randomized clinical trials (RCTs) that evaluated the treatment effects of single-agent or doublet CT+H as first-line therapies for HER2-positive MBC. The main outcomes measured for this study included the overall response rate (ORR), progression-free survival (PFS), and overall survival (OS). A meta-analysis and trial sequential analysis (TSA) were performed, and the study quality was evaluated using the GRADE framework. The PROSPERO registry number of our analysis is CRD42016043766. RESULTS: The results from four RCTs including 1044 participants were pooled. Moderate-quality evidence indicated that compared with single-agent CT+H, doublet CT+H correlated better with prolonged PFS (hazard ratio [HR] 0.69, 95% confidence interval [CI] 0.63-0.75, P < 0.0001) and OS (HR = 0.90, 95% CI 0.88-0.92, P < 0.0001). However, moderate-quality evidence revealed no significant difference between the two regimens regarding the ORR (relative risk [RR] = 1.07, 95% CI 0.98-1.17, P = 0.157), which was confirmed by TSA, indicating that the cumulative Z-curve entered the futility area. Moderate-quality evidence indicated that treatment-related grade 3 or 4 toxicities of thrombocytopenia (RR = 4.08, P = 0.000), nausea/vomiting (RR = 4.26, P = 0.002), diarrhea (RR = 2.81, P = 0.002), and stomatitis (RR = 5.02, P = 0.003) were observed more frequently with doublet CT+H than with single-agent CT+H. CONCLUSIONS: Compared with single-agent CT, the combination of doublet CT with trastuzumab as first-line therapy for HER2-positive MBC is associated with longer PFS and OS, but more treatment-related grade 3 or 4 toxicities. Therefore, doublet CT appears to be an appropriate regimen for HER2-positive MBC with a good performance status.

Decabromodiphenyl ethane (DBDPE) is a kind of new brominated flame retardants, which is widely used as a replace of decabromodiphenyl ether in electronic appliances, textiles and other goods. This review summarizes environmental levels and body burden of human beings of DBDPE in recent years. The data shows that the concentration of DBDPE in the environment and human tissues shows an upward trend. According to limited experiments about its toxicity, DBDPE shows similar toxicity to decabromodiphenyl ether. DBDPE can interfere thyroid hormones balance, and cause damage to liver, reproductive development, kidney, et al, which implies that DBDPE might be another new persistent organic pollutant. Further researches are needed.

INTRODUCTION: Many studies of patients' perception of a medical chaperone have focused on female patients; that of male patients are less well studied. Moreover, previous studies were largely based on patient populations in English-speaking countries. Therefore, this study was conducted to investigate the perception and attitude of male and female Chinese patients to the presence of a chaperone during an intimate physical examination. METHODS: A cross-sectional guided questionnaire survey was conducted on a convenient sample of 150 patients at a public teaching hospital in Hong Kong. RESULTS: Over 90% of the participants considered the presence of a chaperone appropriate during intimate physical examination, and 84% felt that doctors, irrespective of gender, should always request the presence of a chaperone. The most commonly cited reasons included the availability of an objective account should any legal issue arise, protection against sexual harassment, and to provide psychological support. This contrasted with the experience of those who had previously undergone an intimate physical examination of whom only 72.6% of women and 35.7% of men had reportedly been chaperoned. Among female participants, 75.0% preferred to be chaperoned during an intimate physical examination by a male doctor, and 28.6% would still prefer to be chaperoned when being examined by a female doctor. Among male participants, over 50% indicated no specific preference but a substantial minority reported a preference for chaperoned examination (21.2% for male doctor and 25.8% for female doctor). CONCLUSIONS: Patients in Hong Kong have a high degree of acceptance and expectations about the role of a medical chaperone. Both female and male patients prefer such practice regardless of physician gender. Doctors are strongly encouraged to discuss the issue openly with their patients before they conduct any intimate physical examination.

Cryopreservation has been proven significance as a technique for promising the long-term conservation of plant germplasms. This study aimed to establish a cryopreservation protocol for calli of Schisandra chinensis (Turcz.) Baill, and to explore the effects of different process parameters on callus viability. Effects of desiccation duration, cryoprotectants and cryopreservation methods, thawing temperature, and post-culture conditions on the viability of cryopreserved calli were assessed. Among different cryoprotectants and freezing procedures, the highest survival was recorded when the water content of callus after 30 min desiccation was 57.3%, were loaded into a cryoprotectant containing 10% ethylene glycol, 8% glucose, and 10% DMSO, and frozen slowly (-1°C/min). Rapid thawing at 40°C for 2 min demonstrated the best recovery of cryopreserved S. chinensis calli. Post-culturing in darkness for one week before transfer to light conditions (under 16 h photoperiod at 36 µmol·m-2·s-1) was beneficial to callus regeneration. Plants regenerated through somatic embryogenesis from cryopreserved calli remained ploidy stable after cryopreservation. The callus cryopreservation procedure established in this study is a promising tool for the conservation of S. chinensis resources.

Objective: To study the prevalence of obstructive sleep apnea hypopnea syndrome (OSAHS) and its relationship with traffic accidents in the professional drivers. Methods: Questionnaires of OSAHS were sent to 950 professional drivers who had annual physical examination at the Central Hospital of Jiading District in Shanghai from October 2014 to September 2015. Those with moderate to severe snoring and/or Epworth Sleepiness Scale (ESS)≥9 performed the home sleep testing. All drivers were divided into OSAHS and non-OSAHS according to the survey and monitoring. The following parameters were compared such as driving ages, neck circumference, body mass index (BMI), average night sleep time, ESS, hypertension, diabetes, hypertrophy of tonsil and the incidence of traffic accidents. The risk factors of traffic accidents were analyzed by multivariate Logistic regression. Results: Totally 826 responses were eligible, including 578 (70.0%) with self-reported snoring. There was measurement failure involving 3 of 233 the home sleep testing due to sensor off, 823 subjects were included in the study. The prevalence of OSAHS was 13.5% (111/823). The mild, moderate and severe OSAHS were 47, 38 and 26 cases respectively. There were 712 drives without OSAHS. The neck circumference[(39.8±3.8) vs (39.0±3.0) cm]and BMI[(26.7±4.2) vs (24.4±3.8) kg/m2]were significantly higher in the drivers suffering from OSAHS (all P<0.05). The percentage of ESS≥ 9 (57.7% vs 12.6%), hypertension (27.9% vs 5.9%), diabetes (4.5% vs 1.1%), hypertrophy of tonsil (7.2% vs 2.3%) were higher in the drivers with OSAHS (all P<0.05). There were no significant difference in driving ages and average night sleep time between two groups (all P>0.05). The overall incidence of traffic accidents was 5.8% (48/823) in a year. The percentage was respectively 17.1% (19/111) in OSAHS and 4.1% (29/712) in non-OSAHS (P<0.001). Multiple logistic regression analysis showed that sleepiness (OR=30.578, 95%CI: 10.699-87.394; P<0.001), OSAHS (OR=14.062, 95%CI: 4.791-41.269; P<0.001) and vehicle years (OR=2.345, 95%CI: 1.183-4.646; P<0.05)were the risk factors, while the average night sleep time (OR=0.037, 95%CI: 0.014-0.098; P<0.001) was the protective factor. Conclusion: Professional drivers have higher prevalence of OSAHS, which contributes to the increased risk of traffic accidents.

This study aimed to analyze the association between the 405G/C and -2578C/A polymorphisms of the vascular endothelial growth factor (VEGF) gene and breast cancer risk by meta-analysis. A systematic computerized search of PubMed, Google Scholar, and Web of Science databases was performed to identify relevant publications. After rigorous searching and screening, 9 eligible case-control studies were included in this meta-analysis. The associations between the VEGF gene 405G/C and -2578C/A polymorphisms and breast cancer risk were estimated by pooled ORs and 95%CIs using fixed- or random-effect models. Meta-analysis results showed no significant association between the 405G/C polymorphism and breast cancer risk (CC vs GG: OR = 1.04, 95%CI = 0.92-1.17; CC vs GC: OR = 1.04, 95%CI = 0.93-1.17; dominant model: OR = 0.95, 95%CI = 0.85-1.06; recessive model: OR = 0.92, 95%CI = 0.70-1.20). The results also did not show significant association for the -2578C/A polymorphism: (AA vs CC: OR = 1.03, 95%CI = 0.91-1.15; AA vs GA: OR = 0.99, 95%CI = 0.89-1.10; dominant model: OR = 1.00, 95%CI = 0.90-1.10; recessive model: OR = 1.03, 95%CI = 0.94-1.13). Similar results were observed in the subgroup analyses on ethnicity, sample size, and Hardy-Weinberg equilibrium. These findings suggested a lack of association between the VEGF gene 405G/C and -2578C/A polymorphisms and breast cancer susceptibility.

It has been reported that interleukin-10 (IL-10) promoter genes (1082 A/G, 819 T/C, 592 A/C) are associated with nasopharyngeal carcinoma (NPC). However, the results remain controversial and ambiguous. To resolve inconsistencies in published data, we performed a meta-analysis to ascertain the association between IL-10 polymorphisms and NPC risk. Two case-control studies and two cohort studies were quantitatively analyzed to evaluate IL-10 promoter gene polymorphisms and NPC risk. Odds ratios (ORs) and their 95% confidence intervals (CIs) were calculated for each genetic model and allelic comparison. A random-effect model or a fixed-effect model was used to calculate the overall combined risk estimates. Overall, the variant genotypes (AA and AG) of the IL-10-1082 A/G polymorphism were associated with elevated risk of NPC compared with the GG homozygote (AG vs GG: OR = 1.77; 95%CI = 1.39-2.26; AG + GG vs AA: OR = 1.78; 95%CI = 1.42-2.22); no significant associations were observed in allelic contrast and the recessive model. Strong positive association was seen in the cohort studies but not in the case-control studies. No statistically significant association was detected between IL-10-819 T/C and IL-10-592 A/C polymorphisms and NPC. Additionally, publication bias was not found. Based on the current evidence, this meta-analysis suggests that IL-1082 A/G polymorphism may increase the risk of NPC, but IL-10-819 T/C and IL-10-592 A/C polymorphisms do not. Further multicenter studies that are better controlled are required to confirm these findings.

OBJECTIVE: The impact of selenium on autoimmune thyroid disease (AITD) is a subject of ongoing debate. This study aimed to analyze the causal correlations of selenium with autoimmune thyroiditis (AIT), autoimmune hyperthyroidism (AIH), and Graves' disease (GD) by Mendelian randomization (MR). MATERIALS AND METHODS: Single nucleotide polymorphisms related to selenium, AIT, AIH, and GD were sourced from the IEU Open GWAS project and FinnGen. Exposure-outcome causality was assessed using inverse variance weighted, MR-Egger, and weighted median. Horizontal pleiotropy was examined using the MR-Egger intercept, heterogeneity was evaluated with Cochran's Q test, and the robustness of the results was confirmed via leave-one-out sensitivity analysis. RESULTS: The MR analysis revealed that selenium did not exhibit a causal relationship with AIT (OR 0.993, 95% CI 0.786 to 1.108, p=0.432), AIH (OR 1.066, 95% CI 0.976 to 1.164, p=0.154), or GD (OR 1.052, 95% CI 0.984 to 1.126, p=0.138). Moreover, the MR-Egger intercept and Cochran's Q test demonstrated the absence of horizontal pleiotropy or heterogeneity in these results (p>0.05). Sensitivity analysis affirmed the robustness of these results. CONCLUSIONS: This MR analysis concluded that selenium was not linked to AIT, AIH, or GD risk. Therefore, indiscriminate selenium supplementation is not advisable for AITD patients without concurrent selenium deficiency.

OBJECTIVE: This study aimed to systematically evaluate the efficacy, safety and optimal dose of polyethylene glycol loxenatide (PEX168) for treating type 2 diabetes mellitus (T2DM). MATERIALS AND METHODS: Clinical trials of PEX168 for T2DM were identified in 8 databases, with a build time limit of January 2023. Included studies were subjected to meta-analysis and trial sequential analysis (TSA). RESULTS: On the efficacy endpoint, the meta-analysis showed that PEX168 100 µg significantly reduced 0.86% glycated hemoglobin type A1c (HbA1c) (MD -0.86, 95% CI -1.02 - -0.70, p<0.00001), 1.11 mmol/L fasting plasma glucose (FPG) (MD -1.11, 95% CI -1.49 - -0.74, p<0.00001) and 1.91 mmol/L 2h postprandial glucose (PPG) (MD -1.91, 95% CI -3.35 - -0.46, p=0.01) compared with placebo. The TSA showed that all these benefits were conclusive. On safety endpoints, total adverse events (AEs), gastrointestinal (GI) AEs, serious AEs, and hypoglycemia were comparable to placebo for PEX168 100 µg (p>0.05). In the dose comparison, the HbA1c, FPG, and 2h PPG of PEX168 200 µg were comparable to 100 µg (p>0.05), while GI AEs were significantly higher than 100 µg (RR=2.84, 95% CI 1.64-4.93, p=0.0002). CONCLUSIONS: PEX168 100 µg can significantly lower blood glucose and does not increase the risk of total AEs, GI AEs, and hypoglycemia, which may be a preferred glucagon-like peptide-1 receptor agonist for type 2 diabetes mellitus.

BACKGROUND: Few studies look into cerebral blood flow (CBF) changes during emergence from general anaesthesia for craniotomy. The purpose of this study was to assess CBF changes during emergence from general anaesthesia for craniotomy, through monitoring blood oxygen saturation of jugular vein bulb (SjvO2 ) and transcranial Doppler (TCD). METHODS: We enrolled 30 patients undergoing selective craniotomy (group C) for supratentorial brain tumour resection and 30 patients undergoing selective abdominal surgery (group A). Mean velocity of middle cerebral artery (Vmca), mean arterial pressure (MAP), SjvO2 (only measured in group C), and arterial CO2 partial pressure were measured before anaesthesia, at tracheal extubation, and 30, 60, 90, 120 min after extubation. RESULTS: Vmca of the same side of tumour was significantly higher than contralateral Vmca before anaesthesia and at all times after extubation in group C. The ipsilateral Vmca increased significantly (95.7 ± 16.9 cm/s vs. 63.7 ± 6.7 cm/s, P < 0.01) at extubation in group C, then declined but still above baseline significantly in the first 2 h after extubation. While Vmca of the right side changed only slightly (63.6 ± 7.7 cm/s vs. 61.8 ± 8.1 cm/s, P < 0.01) but significantly at extubation in group A. SjvO2 increased significantly (81.4% ± 7.4% vs. 60.9% ± 3.7%, P < 0.01) at extubation in group C, and remained above baseline significantly for 2 h. There was no significant correlation between Vmca and MAP at any time. CONCLUSIONS: Cerebral hyperaemia occurs after supratentorial brain tumour resection surgery. The hyperaemia is more pronounced on the same side as the tumour.

OBJECTIVE: The purpose of this study is to evaluate the combination of iguratimod (IGU) and methylprednisolone (MP) for the efficacy and safety of primary Sjögren's syndrome (pSS) by a meta-analysis and a trial sequential analysis (TSA). MATERIALS AND METHODS: Clinical studies of IGU combined with MP for pSS were searched through eight databases. Revman 5.3 and TSA 0.9.5.10 Beta were used for the meta-analysis and TSA. RESULTS: In terms of efficacy endpoints, compared with "HCQ+MP" group, "IGU+MP" group decreased erythrocyte sedimentation rate (ESR) [mean difference (MD)=-5.15, 95% confidence interval (CI)=(-7.37, -2.93), p<0.0001], immunoglobulin G (IgG) [MD=-3.38, 95% CI=(-4.13, -2.64), p<0.00001], immunoglobulin M (IgM) [MD=-0.64, 95% CI=(-1.19, -0.09), p=0.02], Immunoglobulin A (IgA) [MD=-1.16, 95% CI=(-1.92, -0.39), p=0.003], EULAR Sjögren's Syndrome Disease Activity Index (ESSDAI) [MD=-1.62, 95% CI=(-2.07, -1.17), p<0.0001], EULAR Sjögren's Syndrome Patient Reported Index (ESSPRI) [MD=-2.07, 95% CI=(-2.54, -1.59), p<0.0001], increase platelet (PLT) [MD=13.21, 95% CI=(9.77,16.65), p<0.00001], and improve Schirmer I test (SIT) [MD=1.86, 95% CI=(1.40, 2.32), p<0.0001]. TSA presented that these benefits observed with the current information volume were all conclusive, except for IgM. In terms of safety endpoints, the total adverse event rates (AEs), leucopenia, gastrointestinal (GI) AEs, skin diseases, and liver dysfunction of the "IGU+MP" group and the "HCQ+MP" group were comparable. And TSA indicated that the results need to be confirmed by additional studies. Harbord regression showed no publication bias (p=0.986). CONCLUSIONS: IGU combined with MP effectively attenuates autoimmune responses (IgG, IgM, IgA), reduces clinical symptoms and disease activity (ESR, PLT, ESSPRI, ESSDAI), and improves the exocrine gland functional status (SIT) in patients with pSS. IGU combined with MP does not increase the risk of adverse events, which means that IGU combined with MP may be a safe and effective strategy for the treatment of pSS and has value for further research exploration.
