Distribution and genotyping of hepatitis C virus (HCV) infection in Gansu province, China.

INTRODUCTION: The distribution of common subtypes of hepatitis C virus (HCV) in Gansu province were analyzed. This information provided a theoretical basis for the selection of appropriate antiviral treatment regimens. METHODOLOGY: We collected data on HCV antibody screening tests from 421,802 outpatients and inpatients at the Second Clinical Hospital of Lanzhou University from January 2018 to June 2022. Ribonucleic acid (RNA) viral load, HCV genotypes, and HCV quantification were analyzed retrospectively. The results of HCV positive detection rate, copy number, and genotype distribution were statistically analysed using SPSS 26.0. RESULTS: A total of 421,802 HCV antibody screenings were performed resulting in 4,558 positive cases (1.081%). In addition, 2,345 cases (1.302%) were positive with quantitative HCV antibodies in 180,157 outpatients and inpatients. Quantitative HCV virus RNA was further measured in 2592 outpatients and inpatients. There were 825 positive cases for HCV, with a positivity rate of 31.83%. High-sensitivity quantification of HCV-RNA was performed in 6538 patients, among which 1336 were HCV-RNA positive infections (positivity rate of 20.43%). Among the 1484 genotype tests, 4 genotypes and 10 subtypes were detected, including 4a, 1b, 2a, 2b, 3a, 3b, 6a, 6n, 1b/2a, and 2a/6a, with the majority of results from 2a (51.89%) and 1b (42.72%). CONCLUSIONS: The most prevalent genetic subtype in HCV-positive patients in Gansu was 2a, followed by 1b. In addition, 8 genotype subtypes appeared: 1a, 2b, 3a, 3b, 6a, 6n, 1b/2a and 2a/6a. Understanding the distribution of HCV genes in Gansu province is of significance for the optimization of virus treatment.

Apolipoprotein A1 is associated with osteocalcin and bone mineral density rather than high-density lipoprotein cholesterol in Chinese postmenopausal women with type 2 diabetes mellitus.

Objective: Disturbances in high-density lipoprotein cholesterol (HDL-c) metabolic pathways can affect bone metabolism, which may rely on the particle function of apolipoprotein rather than HDL-c levels. This study aimed to evaluate the correlation of serum HDL-c and apolipoprotein A1 (APOA1) with bone metabolism in Chinese postmenopausal women with type 2 diabetes mellitus (T2DM). Method: A total of 1,053 participants with complete data were enrolled and separated into three groups based on the HDL-c and APOA1 tertiles. The trained reviewer collected demographic and anthropometric information. Bone turnover markers (BTMs) were determined by standard methods. Bone mineral density (BMD) was measured by dual-energy x-ray absorptiometry. Results: Overall, the prevalence of osteoporosis was 29.7%. Groups with higher APOA1 have a remarkably more elevated level of osteocalcin (OC), L1-L4 BMD, and T-score across the APOA1 tertiles. APOA1 presented a positive correlation with OC (r = 0.194, p < 0.001), L1-L4 BMD (r = 0.165, p < 0.001), and T-score (r = 0.153, p < 0.001) rather than HDL-c. Meanwhile, APOA1 remained independently associated with OC (ß = 0.126, p < 0.001), L1-L4 BMD (ß = 0.181, p < 0.001), and T-score (ß = 0.180, p < 0.001) after adjustment for confounding factors. APOA1 is also shown to be independently correlated with osteoporosis after adjustment for confounding factors, and the OR (95%CI) was 0.851 (0.784-0.924). In contrast, there was no significant association between HDL-c and osteoporosis. Furthermore, APOA1 seemed to have the largest areas under the curve (AUC) for osteoporosis. The AUC (95% CI) of APOA1 identifying osteoporosis was 0.615 (0.577-0.652). The optimal cut-off value of APOA1 was 0.89 g/L (sensitivity: 56.5%, specificity: 67.9%). Conclusion: APOA1 is independently associated with OC, L1-L4 BMD, and osteoporosis rather than HDL-c in Chinese postmenopausal women with T2DM.

Diagnosis of parapneumonic pleural effusion with serum and pleural fluid Activin A.

OBJECTIVE: The aim is to evaluate the diagnostic value of Activin A levels in serum and pleural fluid on Parapneumonic Pleural Effusion (PPE). METHODS: The authors collected serum and pleural fluid from 86 PPE and 37 Non-PPE (NPPE) patients. Including Activin A, levels of biomarkers such as Lactate Dehydrogenase (LDH), Procalcitonin (PCT), and C-Reactive Protein (CRP) were measured. All factors were calculated for association with days after admission. The diagnostic potential of biomarkers on PPE was considered by Receiver Operating Characteristic (ROC) curve analysis. RESULTS: Levels of Activin A in serum and pleural fluid of PPE patients were significantly higher than those of the NPPE patients. Moreover, concentrations of Activin A in pleural fluid showed a more obvious relevant days after admission. ROC curve analysis found that Activin A in pleural fluid had AUCs of 0.899 with 93% sensitivity and 84% specificity for PPE diagnosis. CONCLUSION: Activin A in pleural fluid correlated with disease severity could act to diagnose PPE.

Family Functioning is Associated with Post-Stroke Depression in First-Ever Stroke Survivors: A Longitudinal Study.

Background: Post-stroke depression (PSD) can aggravate the mortality and recurrence rate in stroke patients. The relationship between family functioning and PSD at different phases after a first-ever stroke is unclear. The purpose of this longitudinal study was to investigate the patterns and relationship of family functioning and PSD at acute hospitalization and 6 months post-discharge in first-ever stroke survivors. Methods: This is a longitudinal study conducted in Guangzhou, China. Family functioning and depression were measured by the Short Form Family Assessment Device (SF-FAD) and Self-Rating Depression Scale (SDS) at baseline and 6 months post-discharge. Multiple linear regression analysis was used to explore the relationship between family functioning and PSD. Results: The prevalence of PSD at acute hospitalization and 6 months post-discharge was 32.9% and 20.0%, respectively. SDS scores decreased significantly from baseline to 6 months post-discharge, while SF-FAD scores did not change significantly during this period. The Pearson correlation coefficient showed that SF-FAD scores were positively associated with SDS scores at the two time points (r 1 = 0.341, r 2 = 0.510, P < 0.05). Multiple linear regression analyses indicated that SF-FAD scores could predict PSD at baseline (unstandardized coefficient: 7.010, P < 0.05) and 6 months post-discharge (unstandardized coefficient: 9.672, P < 0.001). Conclusion: This study found that first-ever stroke survivors had good family functioning at baseline and 6 months post-discharge. The findings in this study verified that poor family functioning is positively associated with PSD at different phases post-stroke. Good family functioning is an important protective factor against PSD.

Hypotension from afatinib in epidermal growth factor receptor-mutated non-small cell lung cancer: a case report and literature review.

Side effects of afatinib are a problem in patients with advanced non-small cell lung cancer (NSCLC). However, little is known about the occurrence of afatinib-induced hypotension. An 81-year-old man with NSCLC had an epidermal growth factor receptor-positive genotype with the p.L861Q mutation in exon 21. He was administered afatinib (40 mg/day) as anticancer therapy. Hypotension occurred twice after afatinib initiation. He suffered from dizziness and nausea. Blood pressure gradually returned to normal after afatinib cessation. Clinicians should be aware of hypotension in patients with NSCLC after afatinib initiation.

Comparisons of Stroke Knowledge and Health Behaviors in Patients With Hypertensive Stroke at Different Recurrence Risk Strata: The Comprehensive Reminder System Based on the Health Belief Model Study.

BACKGROUND: Risk factor management via behavioral change contributes substantially to secondary stroke prevention. The health belief model identified self-perceived risk as a significant factor in behavior change. In previous studies, people have tended to incorrectly estimate their risk of stroke. Little is known about the differences in stroke knowledge and health behaviors in patients who have had a stroke with different risks of stroke recurrence in China. OBJECTIVE: The aims of this study were to determine the accuracy of self-perceived risk of stroke recurrence and to compare stroke knowledge and health behaviors in patients with hypertensive stroke at different recurrence risk strata. METHODS: Baseline data from 174 patients in the Comprehensive Reminder System based on the Health Belief Model (CRS-HBM) study were used. Self-perceived risk was assessed via the susceptibility subcategory of the Short-Form Health Belief Model Scale, and actual risk was stratified using the Essen Stroke Risk Score. RESULTS: Only 27.0% of the patients estimated their risks of stroke recurrence accurately. Patients who perceived themselves to be at higher risk had better knowledge of warning signs. Compared with patients who underestimated their risk of stroke recurrence, those who accurately estimated or overestimated their risk less likely to smoke. CONCLUSIONS: Most patients incorrectly estimated their risk of stroke recurrence. Communicating with patients about their future risk of recurrent stroke may help improve their stroke knowledge and health behaviors. Implementation of the Comprehensive Reminder System based on the Health Belief Model focusing on risk education aimed at prevention of stroke recurrence is warranted in China.

[Investigation of microbial community involved in fermentation of Massa Medicata Fermentata].

This study aimed to clarify the microbial diversity, dominant species and the change of community structures in the fermentation of Liushenqu(Massa Medicata Fermentata), and explore the material foundation of its pharmacodynamics effect. On the basis of standardizing the fermentation process, Massa Medicata Fermentata was prepared by screening and optimizing the recipes and the standard formula issued by the Ministry. The community structure and growth process of fungi and bacteria in the samples at five time points(0, 17, 41, 48, 65 h) in the fermentation process of Massa Medicata Fermentata were analyzed by using isolation and culture of eight different media and high-throughput DNA sequencing technology. The results indicated that the samples of the two recipes pre-sented high microbial diversity at the initial fermentation stage, with Aspergillus spp. as the dominant species. As the fermentation process goes forward, Saccharomycopsis fibuligera and Rhizopus oryzae soon became dominant species from 17 h after fermentation commencement point to the fermentation end, while the other species were inhibited at a lower level from 17 h. The species diversity of bacteria in the initial fermentation samples was also high, and Enterobacter was the dominant species. Enterobacter cloacae, Pediococcus pentosaceus and Cronobacter sakazakii became dominant bacterial species 17 h after fermentation commencement, while the species diversity was decreased. Our results will be a scientific basis for promoting the fermentation process of Massa Medicata Fermentata by using pure microbial cultures.

Relationship between risk perception and lifestyle in ischemic stroke patients with H-type hypertension.

BACKGROUND: Patients with ischemic stroke who have H-type hypertension are at an increased risk of recurrent stroke. The relationship between risk perception and lifestyle in these patients has not been fully explored. The objective of this study is to investigate risk perceptions and lifestyles among H-type hypertensive ischemic stroke patients and explore their relationships. METHODS: A total of 314 hypertensive ischemic stroke patients were divided according to homocysteine (Hcy) level into the normal Hcy and high Hcy group using convenience sampling. The high Hcy group was further divided into the perceived or non-perceived group based on the patients' risk perceptions. The Essen Stroke Risk Score and the Health Behavior Scale were used to investigate the patients' risk perceptions and lifestyles. RESULTS: The perceived risk factors in the high Hcy group included hypertension, diabetes, alcohol consumption, hyperlipidemia, and smoking, which showed no significant difference with those in the normal Hcy group. The high Hcy group had a total lifestyle score of (2.54±0.42). The perceived group had a better lifestyle than the non-perceived group; however, only blood pressure monitoring compliance showed a significant difference between the groups (P<0.05). The lifestyles of subjects whose perceived risks included diabetes, hyperlipidemia, smoking, and alcohol consumption were not significantly different to those in the non-perceived group. CONCLUSIONS: Patients with H-type hypertensive ischemic stroke who perceive hypertension as a risk factor have relatively good lifestyles. Therefore, efforts should be made to strengthen risk education for these patients to help improve their risk perception and lifestyles.

Risk factors for Blastocystis infection in HIV/AIDS patients with highly active antiretroviral therapy in Southwest China.

BACKGROUND: Blastocystis is a widespread zoonotic protozoan of mammalian species, especially in HIV/AIDS individuals. The aim of this study was to analyze the prevalence and risk factors related with Blastocystis infection among HIV/AIDS patients in Southwest China. METHODS: The cross-sectional study was performed in 311 HIV/AIDS cases in Tengchong City, Yunnan Province from July 2016 to March 2017. For each subject, stool specimen was collected to detect the Blastocystis, and the blood sample was used to detect HIV virus load and CD4+ T cell count, in addition, structured questionnaire was used to collect the basic information and risk factors. FINDINGS: The result showed that the detection rate of Blastocystis was 3.86% (95% CI: 2.22-6.62) among HIV/AIDS patients. Both raising animal (OR = 12.93, 95% CI: 1.54-108.36) and drinking un-boiled water (OR = 8.17, 95% CI: 1.76-37.90) were risk factors for Blastocystis infection in HIV/AIDS individuals. In addition, the interaction of CD4+ T cell count and HIV virus load was also contribution to Blastocystis infection (P = 0.007). CONCLUSIONS: A high prevalence of Blastocystis infection was found in HIV/AIDS patients in Tengchong. Poor hygienic habits, the interaction of HIV virus load and CD4+ T cell count were identified as main risk factors for infection. These results will help us to develop efficient control strategies to intervene with and prevent the occurrence of Blastocystis among HIV-infected individuals.

The prognostic role of MAC30 in advanced gastric cancer patients receiving platinum-based chemotherapy.

AIM: We aimed to investigate a practical profile of MAC30 on chemotherapeutic response in gastric cancer (GC). PATIENTS & METHODS: We elected 87 GC patients receiving platinum-based chemotherapy in this study. MAC30 levels in tumor and adjuvant nontumor tissues were confirmed via reverse transcription-PCR to identify the clinical profile in GC and the correlation with therapeutic response. RESULTS: We found elevated MAC30 in GC compared with the matched adjacent nontumor tissues. GC with enhanced MAC30 exhibited poorer survival by Kaplan-Meier analysis and poor response to adjuvant platinum-based chemotherapy. A multivariate analysis showed that MAC30 was an independent prognostic factor of overall survival in GC receiving platinum-based chemotherapy. CONCLUSION: MAC30 could play as a potential biomarker for prognosis of GC with platinum-based chemotherapy.

[Clinical Significance of Minimal Residual Disease in Risk Stratification and Prognosis of Childhood B-lineage Acute Lymphoblastic Leukemia].

OBJECTIVE: To explore clinical significance of monitoring the level of minimal residual disease (MRD) at different time point in the risk stratification and prognosis of Childhood B-lineage Acute Lymphoblastic Leukemia. METHODS: Three hundred and eighty cases of children's B-ALL from Augest 2008 to January 2013 in our hospital were enrolled in this study. MRD levels were detected at day 15, day 33 and week 12 after initial chemotherapy. The event-free survival(EFS) and overall survival (OS) were measured on the basis of MRD levels at different stages of chemotherapy and were compared by Kaplan Meier analyses. RESULTS: The patient's age, initial white blood cell count, chromosome, MLL, BCR/ABL, pretreatment reaction, bone marrow MRD at days 33 were closely related with the 5-year EFS rate. Multiparameter flow cytometry showed the marked MRD and unmarked MRD were not significantly different between their 5-year EFS rate(P>0.05), and the every immune phenotype was also no significantly different between the 5-year EFS rate(P>0.05). The children with MRD≥10-2 at day 15(P<0.01), MRD≥10-3 at day 33 (P<0.01) and MRD≥10-3 on week 12(P<0.01) have a decreased 5-year EFS rate and overall survival, which related with poor prognosis obviously. The 5-year EFS rates at the MRD<10-4(negative), 10-4-10-3, 10-3-10-2 and ≥10-2 at day 33 were 86.6±2.7%, 77.5±4.9%, 70.1±8.0%, and 44.8±9.9%(P<0.01) with significant difference respectively; the 5-year OS rate was 89.5±2.7%, 80±4.9%, 76.0±7.8%, and 53.2±10.1% with statistically significant difference(P<0. 01). CONCLUSION: The MRD≥10-2 at day 33 is a high risk factor for significant reduction of the 5-year EFS rate and the 5-year OS rate of children with B-ALL. Thus, dynamic monitoring the MRD level can predict relapse of B-ALL after remission.

[Clinical Features and Prognostic Factors of Children with Acute Lymphoblastic Leukemia in High-Risk Group].

OBJECTIVE: To explore the clinical features and prognostic factors of pediatric acute lymphoblastic leukemia (ALL) in high-risk (HR) group. METHODS: A total of 421 children with ALL in the Children's Hospital of Soochow University from August 2008 to March 2013 were diagnosed and treated according to the Chinese Children Leukemia Group (CCLG)-2008 Protocol. Among different risk-groups, 148 cases were stratified into the low-risk group and 191 cases were included in the moderate-risk group. Eight-two patients of the high-risk group were analyzed retrospectively for their clinical features, 5-year event-free survival (EFS) rate and overall survival (OS) rate. RESULTS: The median follow-up times of 82 patients were 64 months(3.0-76.3 months), 55 patient achieved complete remission(CR) after 1 cycle of induction chemotherapy(CR rate 67.1%), 25 patients relapsed(30.5%) mainly in very early and early relapse phases, significantly different from the low-risk group (P=0.013), 27 pateitns died(32.9%). The 5-year pEFS and pOS were 57.20% and 58.5%, respectively. Ph+ or BCR/ABL+ and MRD>10-2 on the 33rd day in the high-risk group were 2 main factors influencing EFS and OS according to single factor analysis. Ph+ or BCR/ABL+ was an independent prognostic factor, however, the MRD value on the 33rd day was not statistically significant differente by virtue of COX regression analysis. CONCLUSION: The clinical feature of children with ALL in high risk group display low induction CR rate, high recurrence rate and the lower 5-year pEFS. Ph+ or BCR/ABL+ is regarded as an independent factor of poor prognosis.

The Prognostic Effect of MAC30 Expression on Patients With Non-Small Cell Lung Cancer Receiving Adjuvant Chemotherapy.

The purpose of this study was to examine the MAC30 expression in non-small cell lung cancer and to evaluate its prognostic value on therapeutic response in patients with non-small cell lung cancer receiving postoperative chemotherapy. Among a total of 218 retrospective Chinese patients with non-small cell lung cancer, 164 patients receiving adjuvant chemotherapy were enrolled in this study. Real-time polymerase chain reaction was performed to confirm the expression of MAC30 messenger RNA in 32 cases of non-small cell lung cancer tumors with the corresponding nontumor lung tissues. The MAC30 protein expression in all specimens was analyzed by immunohistochemical staining. Moreover, we assessed the correlation of MAC30 expression with clinicopathological features, therapeutic response, and survival of patients. Here, we observed the increased expression of MAC30 messenger RNA in patients with non-small cell lung cancer compared to those in control samples. The overexpression of MAC30 was strongly associated with poor tumor differentiation, high tumor-node-metastasis stage, and lymph node metastasis. In addition, we observed that patients with increased MAC30 expression showed gloomy overall survival and disease-free survival. A multivariate analysis explicated that higher MAC30 expression was a valuable independent prognostic factor of poorer tumor differentiation, shorter overall survival, and disease-free survival in patients receiving chemotherapy. MAC30 could be a useful biomarker of tumor differentiation and outcome of patients with non-small cell lung cancer. Overexpression of MAC30 predicts a worse tumor differentiated stage and prognosis in patients with non-small cell lung cancer receiving adjuvant chemotherapy.
