ABSTRACT
AIM: To evaluate the trending visual performance of different intraocular lenses (IOLs) over time after implantation. METHODS: Ninety-one patients received cataract surgery with implantations of monofocal (Mon) IOLs, segmental refractive (SegRef) IOLs, diffractive (Dif) IOLs, and extended-depth-of-focus (EDoF) IOLs were included. The aberrations and optical quality collected with iTrace and OQAS within postoperative 6mo were followed and compared. RESULTS: Most of the visual parameters improved over the postoperative 6mo. The postoperative visual acuity (POVA) of the Mon IOL, SegRef IOL, and EDoF IOL groups achieved relative stability in earlier states compared with the Dif IOL group. Nevertheless, the overall visual performance of the 3 IOLs continued to upturn in small extents within the postoperative 6mo. The optical quality initially improved in the EDoF IOL group, then in the Mon IOL, SegRef IOL, and Dif IOL groups. POVA and objective visual performance of the Mon IOL and EDoF IOL groups, as well as POVA and visual quality of the Dif IOL group, improved in the postoperative 1mo and stabilized. Within the postoperative 6mo, gradual improvements were observed in the visual acuity and objective visual performance of the SegRef IOL group, as well as in the postoperative optical quality of the Dif IOL group. CONCLUSION: The visual performance is different among eyes implanted with different IOLs. The findings of the current study provide a potential reference for ophthalmologists to choose suitable IOLs for cataract patients in a personalized solution.
ABSTRACT
Laparoscopic surgery is extensively applied in the treatment of hepatobiliary diseases. Hepatic artery pseudoaneurysm (HAP) is a rare complication following hepatic biliary surgery through laparoscopy. The clinical manifestations of HAP are diverse and can be fatal. Given its severity, rapid assessment and management are crucial to ensuring a good prognosis. Here, we report three cases of HAP; two underwent laparoscopic surgery due to cholelithiasis, and another caused by trauma. The first case exhibited a pseudoaneurysm involving the distal portion of the right hepatic artery main trunk. The second patient had a pseudoaneurysm at the bifurcation of the left and right hepatic arteries. The third case involved a patient with a pseudoaneurysm involving a branch of the right hepatic artery. The main clinical manifestations of all three cases were bleeding from the biliary tract (the first two cases showed postoperative bleeding in the T-tube, while the third case exhibited gastrointestinal bleeding). The final diagnosis was obtained through digital subtraction angiography. The three patients underwent successful transcatheter arterial embolization operation and a follow-up revealed they were disease-free and alive. This article aims to highlight a rare complication of laparoscopic hepatobiliary surgery and share our experience in early diagnosis and treatment of HAP.
ABSTRACT
BACKGROUND: Postoperative performance, including best corrected distance visual acuity (BCDVA) and optical metrics (from the OQAS and iTrace devices), was compared among 4 different intraocular lenses (IOLs). METHODS: This prospective observational study included 104 eyes from 104 subjects who underwent cataract surgery combined with implantation of 4 different IOLs: monofocal (Mon) IOLs, segmental refractive (SegRef) IOLs, diffractive (Dif) IOLs and extended depth of focus (EDoF) IOLs. Postoperative BCDVA and optical metrics were collected at the 6th month. The OQAS optical metrics included the objective scattering index (OSI), Strehl ratio (SR), modulation transfer function (MTF) cut-off frequency, and predicted visual acuity (PVA); the iTrace optical metrics included blur/double vision, glare/halo, starburst, mixed focus, night myopia, and night hyperopia. RESULTS: There was no significant difference in BCDVA among the 4 groups (P = 0.059; power = 70.3%). Differences were observed in all OQAS optical metrics among the groups (all P < 0.001). Overall, Mon IOLs and EDoF IOLs exhibited better performance than Dif IOLs and SegRef IOLs. Starburst was the only iTrace optical metric that differed among the groups (P < 0.001): SegRef IOLs caused more starbursts than Mon IOLs (P = 0.001), Dif IOLs (P = 0.006) and EDoF IOLs (P < 0.001). Spearman rank correlation analysis was used to determine the relationships among the iTrace optical metrics, OQAS optical metrics and BCDVA: starburst was negatively correlated with BCDVA, PVA at contrasts of 100% and 20%, OSI, and MTF cut-off frequency (all P ≤ 0.001); mixed focus was positively correlated with BCDVA, PVA at contrasts of 100% and 20%, OSI, and MTF cut-off frequency (all P ≤ 0.001). CONCLUSIONS: Postoperative BCDVA and optical metrics varied among the different IOLs, which should be taken into account in the selection and management of IOLs for cataract patients. TRIAL REGISTRATION: This study was approved by the First Affiliated Hospital of Guangzhou Medical University Ethical Review Board (No. 50 2022).

Background: It has been proposed that bacterial lysates may serve as a suitable immunomodulatory oral medication to improve and control asthma symptoms. However, the difference in its efficacy in adults and children remains unclear. Methods: Randomized controlled trials (RCTs) evaluating OM-85 add-on therapy in asthma patients up to December 2021 were searched using PubMed, Scopus, Web of Science, China National Knowledge Infrastructure (CNKI), Wanfang database, and WP (WeiPu) database. Risk of bias was evaluated using the Cochrane risk of bias assessment tool. Results: A total of 36 studies were included. The results showed that OM-85 add-on treatment provided a 24% improvement in asthma symptom control [relative rates (RR) =1.24, 95% confidence intervals (CI): 1.19-1.30], and also significantly improved lung function, increased numbers of T-lymphocytes and the subtypes, and elevated levels of interferon-γ (IFN-γ), interleukin-10 (IL-10), and IL-12. Levels of serum immunoglobulin E (IgE), eosinophil cationic protein (ECP) and pro-inflammatory cytokines (including IL-4 and IL-5) were suppressed in the OM-85 add-on treatment group. Moreover, OM-85 add-on treatment showed more prominent effects in asthmatic children than in asthmatic adults. Conclusions: OM-85 add-on therapy showed important clinical benefits for patients with asthma, especially asthmatic children. Further studies focusing on the immunomodulatory function of OM-85 in personalized asthma treatment are warranted.
ABSTRACT
Abnormal immunological indicators associated with disease severity and mortality in patients with COVID-19 have been reported in several observational studies. However, there are marked heterogeneities in patient characteristics and research methodologies in these studies. We aimed to provide an updated synthesis of the association between immune-related indicators and COVID-19 prognosis. We conducted an electronic search of PubMed, Scopus, Ovid, Willey, Web of Science, Cochrane library, and CNKI for studies reporting immunological and/or immune-related parameters, including hematological, inflammatory, coagulation, and biochemical variables, tested on hospital admission of COVID-19 patients with different severities and outcomes. A total of 145 studies were included in the current meta-analysis, with 26 immunological, 11 hematological, 5 inflammatory, 4 coagulation, and 10 biochemical variables reported. Of them, levels of cytokines, including IL-1ß, IL-1Ra, IL-2R, IL-4, IL-6, IL-8, IL-10, IL-18, TNF-α, IFN-γ, IgA, IgG, and CD4+ T/CD8+ T cell ratio, WBC, neutrophil, platelet, ESR, CRP, ferritin, SAA, D-dimer, FIB, and LDH were significantly increased in severely ill patients or non-survivors. Moreover, non-severely ill patients or survivors presented significantly higher counts of lymphocytes, monocytes, lymphocyte/monocyte ratio, eosinophils, CD3+ T,CD4+T and CD8+T cells, B cells, and NK cells. The currently updated meta-analysis primarily identified a hypercytokinemia profile with the severity and mortality of COVID-19 containing IL-1ß, IL-1Ra, IL-2R, IL-4, IL-6, IL-8, IL-10, IL-18, TNF-α, and IFN-γ. Impaired innate and adaptive immune responses, reflected by decreased eosinophils, lymphocytes, monocytes, B cells, NK cells, T cells, and their subtype CD4+ and CD8+ T cells, and augmented inflammation, coagulation dysfunction, and nonpulmonary organ injury, were marked features of patients with poor prognosis. Therefore, parameters of immune response dysfunction combined with inflammatory, coagulated, or nonpulmonary organ injury indicators may be more sensitive to predict severe patients and those non-survivors.

Rural environments and microbiota are linked to a reduction in the prevalence of allergies. However, the mechanism underlying the reduced allergies modulated by rural residency is unclear. Here, we assessed gut bacterial composition and metagenomics in urban and rural children in the EuroPrevall-INCO cohort. Airborne dusts, including mattress and rural henhouse dusts, were profiled for bacterial and fungal composition by amplicon sequencing. Mice were repeatedly exposed to intranasal dust extracts and evaluated for their effects on ovalbumin (OVA)-induced allergic airway inflammation, and gut microbiota restoration was validated by fecal microbiota transplant (FMT) from dust-exposed donor mice. We found that rural children had fewer allergies and unique gut microbiota with fewer Bacteroides and more Prevotella. Indoor dusts in rural environments harbored higher endotoxin level and diversity of bacteria and fungi, whereas indoor urban dusts were enriched with Aspergillus and contained elevated pathogenic bacteria. Intranasal administration of rural dusts before OVA sensitization reduced respiratory eosinophils and blood IgE level in mice and also led to a recovery of gut bacterial diversity and Ruminiclostridium in the mouse model. FMT restored the protective effect by reducing OVA-induced lung eosinophils in recipient mice. Together, these results support a cause-effect relationship between exposure to dust microbiota and allergy susceptibility in children and mice. Specifically, rural environmental exposure modulated the gut microbiota, which was essential in reducing allergy in children from Southern China. Our findings support the notion that the modulation of gut microbiota by exposure to rural indoor dust may improve allergy prevention.

BACKGROUND: Previous studies have suggested that in-hospital mortality is higher in younger women with ST-segment elevation myocardial infarction (STEMI) than in men. However, more coronary artery disease diagnoses occurred in patients older than 60 years. AIM OF THE STUDY: This study sought to investigate the temporal trends and sex differences in revascularization and in-hospital outcomes in older STEMI patients. METHODS: National Inpatient Sample databases from 2005-2014 were utilized to identify all STEMI patients with age greater than 60 years old. We studied the temporal trends and sex differences in revascularization therapies and in-hospital mortality. RESULTS: From 2005-2014, there were 192,204 older adults diagnosed with STEMI. Older women with STEMI were less likely to receive reperfusion (percutaneous coronary intervention (PCI) adjusted OR: 0.90; 95% CI: 0.87-0.92) compared to older men. Also, the adjusted odds ratio comparing the likelihood of receiving PCI between women and men decreased by an annual average of 0.9% (p = 0.028). Older women had higher in-hospital mortality than men (adjusted OR: 1.12; 95% CI: 1.08 to 1.17). There was no significant change of adjusted in-hospital mortality in both genders (all p >0.05). CONCLUSIONS: Older women were less likely to receive revascularization for STEMI, and this gap was increasing during the study period. Older women had higher in-hospital mortality as compared with older men, but there was no significant temporal change for both genders. These findings present an opportunity to bridge the gender-gap in providing care to older patients with STEMI.

Seco-sativene sesquiterpenoids are an important member of phytotoxins and plant growth regulators isolated from a narrow spectrum of fungi. In this report, eight seco-sativene sesquiterpenoids (1-8) were first analyzed using the UPLC-Q-TOF-MS/MS technique in positive mode, from which their mass fragmentation pathways were suggested. McLafferty rearrangement, 1,3-rearrangement, and neutral losses were considered to be the main fragmentation patterns for the [M+1]+ ions of 1-8. According to the structural features (of different substitutes at C-1, C-2, and C-13) in compounds 1-8, five subtypes (A-E) of seco-sativene were suggested, from which subtypes A, B/D, and E possessed the diagnostic daughter ions at m/z 175, 189, and 203, respectively, whereas subtype C had the characteristic daughter ion at m/z 187 in the UPLC-Q-TOF-MS/MS profiles. Based on the fragmentation patterns of 1-8, several known compounds (1-8) and two new analogues (9 and 10) were detected in the extract of plant pathogen fungus Bipolaris sorokiniana based on UPLC-Q-TOF-MS/MS analysis, of which 1, 2, 9, and 10 were then isolated and elucidated by NMR spectra. The UPLC-Q-TOF-MS/MS spectra of these two new compounds (9 and 10) were consistent with the fragmentation mechanisms of 1-8. Compound 1 displayed moderate antioxidant activities with IC50 of 0.90 and 1.97 mM for DPPH and ABTS+ scavenging capacity, respectively. The results demonstrated that seco-sativene sesquiterpenoids with the same subtypes possessed the same diagnostic daughter ions in the UPLC-Q-TOF-MS/MS profiles, which could contribute to structural characterization of seco-sativene sesquiterpenoids. Our results also further supported that UPLC-Q-TOF-MS/MS is a powerful and sensitive tool for dereplication and detection of new analogues from crude extracts of different biological origins.
ABSTRACT
BACKGROUND: Hepatocellular carcinoma (HCC) is the second leading cause of cancer-related death worldwide, and has relatively high recurrence rates. Few studies have been published on the clinical stages of recurrent HCC. AIM: To assess the applicability of the Barcelona Clinic Liver Cancer (BCLC) staging for recurrent HCC and the need to establish clinical stage criteria for recurrent HCC. METHODS: The clinicopathological data of 81 patients with recurrent HCC who were admitted to the Hospital of Guangxi Zhuang Autonomous Region from January 2013 to December 2017 were collected. The patients were divided into three groups according to the BCLC staging system as follows: (1) Group A with BCLC stage A, 51 patients; (2) Group B with BCLC stage B, 14 patients; and (3) Group C with BCLC stage C, 16 patients. The median time to tumor recurrence and the median overall survival were compared. RESULTS: The median time to tumor recurrence in groups A, B, and C was 16 ± 1.5 mo, 10 ± 2.8 mo, and 6 ± 0.5 mo, respectively, with a statistically significant difference among them (χ 2 = 70.144, P < 0.05); no statistically significant difference was noted between group A and group B (χ 2 = 2.659, P > 0.05), although there were statistically significant differences between group A and group C and between group B and group C (χ 2 = 62.110, and 19.972, P < 0.05). The median overall survival in groups A, B, and C were 42 ± 5.1 mo, 22 ± 3.1 mo, and 13 ± 1.8 mo, respectively, with a statistically significant difference among them (χ 2 = 38.949, P < 0.05); there were statistically significant differences between group A and group B, group A and group C, and group B and group C (χ 2 = 9.577, 37.172, and 7.183, respectively; P < 0.05). CONCLUSION: There are different prognoses in recurrent HCC patients according to the BCLC staging. Therefore, BCLC staging is applicable to recurrent HCC and it is essential to formulate clinical stage criteria for recurrent HCC.
ABSTRACT
T7 peptide is considered as an antiangiogenic polypeptide. The presents study aimed to further detect the antiangiogenic mechanisms of T7 peptide and determine whether combining T7 peptide and meloxicam (COX-2/PGE2 specific inhibitor) could offer a better therapy to combat hepatocellular carcinoma (HCC). T7 peptide suppressed the proliferation, migration, tube formation, and promoted the apoptosis of endothelial cells under both normoxic and hypoxic conditions via integrin α3ß1 and αvß3 pathways. Cell proliferation, migration, apoptosis, or tube formation ability were detected, and the expression of integrin-associated regulatory proteins was detected. The anti-tumor activity of T7 peptide, meloxicam, and their combination were evaluated in HCC tumor models established in mice. T7 peptide suppressed the proliferation, migration, tube formation, and promoted the apoptosis of endothelial cells under both normoxic and hypoxic conditions via integrin α3ß1 and αvß3 pathways. Meloxicam enhanced the activity of T7 peptide under hypoxic condition. T7 peptide partly inhibited COX-2 expression via integrin α3ß1 not αvß3-dependent pathways under hypoxic condition. T7 peptide regulated apoptosis associated protein through MAPK-dependent and -independent pathways under hypoxic condition. The MAPK pathway was activated by the COX-2/PGE2 axis under hypoxic condition. The combination of T7 and meloxicam showed a stronger anti-tumor effect against HCC tumors in mice. The data highlight that meloxicam enhanced the antiangiogenic activity of T7 peptide in vitro and in vivo.

Allergic asthma is a public health problem that affects human health and socioeconomic development. Studies have found that the prevalence of asthma has significantly increased in recent years, which has become particularly pronounced in developed countries. With rapid urbanization in China in the last 3 decades, the prevalence of asthma has increased significantly in urban areas. As changes in genetic backgrounds of human populations are limited, environmental exposure may be a major factor that is responsible for the increased prevalence of asthma. This review focuses on environmental components of farms and rural areas that may have protective effects in reducing the development of asthma. Farm and rural related microorganism- and pathogen-associated molecular patterns are considered to be important environmental factors that modulate host's innate and adaptive immune system to induce protection effects later in life. Environmental microbial-related immunotherapy will also be discussed as the future research direction for the prevention of allergic asthma.
ABSTRACT
RATIONALE: There is controversy regarding the optimal surgical approach for pancreatic lesions in the center of the pancreas. Duodenum-preserving pancreatic cental resection compared with pancreaticoduodenectomy is technically more challenging, but preserves more functional pancreatic tissue. PATIENT CONCERNS: A 34-year-old woman was admitted to our department on March 15, 2017. Computed tomographic's and magnetic resonance cholangiopancreatography's diagnosis was a solitary tumor 3.0â×â2.2-cm lesion located in border between pancreatic neck and body. The patient's condition was good and symptomless, without any disease history. Physical examination and routine blood investigations were normal. All pancreatic malignant tumor biological markers were negative. DIAGNOSES: Solid pseudopapillary neoplasm (SPN) of pancreas. INTERVENTIONS: Total laparoscopic central pancreatectomy with Roux-Y pancreaticojejunostomy was performed, and unscheduled open surgery was done for abdominal pain caused by intraperitoneal bleeding. OUTCOMES: The recovery was smooth after unscheduled open surgery. At the end of 20 months follow-up, she was well and showed no signs of recurrence. LESSONS: The anatomy of the operation is clearer and easier than open surgery because of the magnification effect of laparoscopy. Total laparoscopic central pancreatectomy is safe, effective, feasible for SPN of pancreas, and it should be equally applicable to some other pancreatic cystic neoplasms and neuro-endocrine tumors. Suture is the best measure to prevent postoperative angiorhagia of intraperitoneal cavity.

RATIONALE: There is controversy regarding the optimal surgical approach for pancreatic lesions in the head of the pancreas. Duodenum-preserving pancreatic head resection compared with pancreaticoduodenectomy is technically more challenging, but preserves more functional pancreatic tissue. PATIENT CONCERNS: A 25-year-old woman was admitted to our department on May 10, 2017. Computed tomographic's saw a 2.0â×â2.1-cm lesion located in the head of pancreas and its diagnosis was nonfunctional neuroendocrine tumors? The magnetic resonance cholangiopancreatography scan demonstrated a solitary 1.6â×â1.7-cm lesion located in the head of pancreas, and its diagnosis was tumor. The patient's condition was good and symptomless, without any disease history. Physical examination and routine blood investigations were normal. All pancreatic malignant tumor biological markers were negative. DIAGNOSES: Solid pseudopapillary neoplasm of pancreas. INTERVENTIONS: Total laparoscopic head pancreatectomy with Roux-Y pancreaticojejunostomy was performed. OUTCOMES: The recovery was smooth after surgery. At the end of 20 months follow-up, she was well and showed no signs of recurrence. LESSONS: The anatomy of the operation is clearer and easier than open surgery because of the magnification effect of laparoscopy.

BACKGROUND: To compare the outcomes of liver resection (LR) with radiofrequency ablation (RFA) for patients with hepatitis B virus (HBV)-related small hepatocellular carcinoma (HCC). METHODS: A total of 122 HBV-related small HCC patients who underwent LR (n=64) or RFA (n=58) were involved in this retrospective study. Their basic clinical data, postoperative complications, survival outcomes, and prognostic factors were compared and analyzed. RESULTS: Patients in the LR group had more serious complications (11 versus 0) and longer postoperative hospital stays (11.3 versus 6.0 days) than those in the RFA group (all P<0.05). LR was associated with better recurrence-free survival (RFS) rates at 1, 3, and 5 years compared with RFA (90.4%, 65.9%, and 49.5% versus 79.3%, 50.3%, and 35.6%, P=0.037), but there was no significant difference in overall survival (OS) (95.2%, 78.1%, 58.6% versus 93.1%, 71.3%, 52.9%, P=0.309). Multivariate Cox analysis showed that the hepatic cirrhosis (hazard ratio [HR]: 2.13), tumor number (HR: 3.73), tumor diameter (HR: 1.92), and postoperative anti-HBV therapy (HR: 0.53) had predictive values for RFS, and the latter three (HR: 4.34, 2.30, and 0.44) were independent predictors of OS (all P<0.05). CONCLUSION: LR might be considered the preferred method for patients with HBV-related small HCC, while RFA could apply to selective cases. Anti-HBV therapy after treatment was recommended.
