RESUMO

Objective: To improve the clinical recognition of electronic cigarette or vaping product use-associated lung injury. Methods: A 67 year old patient with lung injury induced by e-cigarette was reported. The concentrations of vitamin E acetate (VEA) and tetrahydrocannabinol (Δ9-THC) in BALF were measured by UHPLC-MS/MS. A literature review was performed with"Vaping-Associated Lung Injury""vape","e-cigarette","electronic cigarette","EVALI","electronic nicotine device","lung","injury","case"as Mesh terms in PubMed. Results: There were 208 cases reported in the literature, 71.6% of whom were male, and 28.4% were female, with a median age of 27 years (17-67 years), while 2 patients (1%) were over 60 years old. The median time of using e-cigarette was 90 days (2 weeks-3 years). Of the 208 patients, the most common symptoms were dyspnea, fever, chest pain, hemoptysis, and gastrointestinal symptoms such as nausea, abdominal pain or diarrhea. The most common manifestation of chest CT was bilateral ground glass opacity (n=119, 57.2%). A total of 70 patients received bronchoscopy and BALF, which showed that the ratio of macrophages was (49.5±29.8)%, neutrophil (34.7±28.7)%, lymphocytes (10.1±7.4)%, and eosinophils (2.4±3.6)%. The "foamy" alveolar macrophages were positive in 65 cases (92.9%).A total of 132 patients (63.5%) were treated with antibiotics, and 162 patients (77.9%) were treated with glucocorticoids. The initial dose of methylprednisolone was 40 mg and the maximum was 500 mg. 48 patients (23.1%) were mechanically ventilated and 10 patients (4.8%) were treated with extracorporeal membrane oxygenation (ECMO). Of the 208 patients, 202(97.1%) patients improved and 6 (2.9%) died. Conclusion: Our case and reported cases should alert physicians to the clinical presentation of vaping-associated lung injury for early diagnosis and prompt management. It is suggested that the standardized management of e-cigarette should be strengthened to avoid similar situation of e-cigarette-related lung injury in China. Additional work is needed to characterize the pathophysiology of this disease.

RESUMO

To evaluate the efficacy of the Asia-Pacific colorectal screening (APCS) score combined with the quantitative fecal immunochemical test in colorectal neoplasia screening. Subjects who appointment to receive colonoscopy were recruited from August 2017 to May 2019 in the digestive endoscopy center. Before the colonoscopy, all subjects were scored by the Asia Pacific colorectal cancer screening scoring system and measured by quantitative fecal immunochemical test (QFIT). The detection rates of colorectal neoplasia were compared to evaluate the efficacy of the combined assay in colorectal neoplasia screening between APCS score and QFIT. A total of 1 420 subjects were enrolled in this study, APCS score medium-risk (MR) and high-risk (HR) groups were 847 (59.7%) and 573 (40.4%) and 26 cases (1.8%) of colorectal cancer, 196 cases (13.8%) of advanced adenoma, and 395 cases (27.8%) of non-advanced adenoma were detected. With the combination of APCS score and QFIT, participants were classified into 4 groups high-risk with positive QFIT result group G1, high-risk with negative QFIT result group G2, medium-risk with positive QFIT group G3, medium-risk negative QFIT group G4. The prevalence of colorectal neoplasia was 64.3%, 16.4%, 55.0%, and 9.8%, respectively. The prevalence of advanced neoplasia in high-risk with QFIT results was significantly higher than that in other 3 groups. HR and positive QFIT were the indicators for further colonoscopy, and MR with FIT negative group could postpone colonoscopy and conduct annual QFIT follow-up. The combination of APCS score and QFIT for colorectal neoplasia screening can reduce unnecessary colonoscopy, improve colonoscopy compliance and screening efficiency, and has important clinical significance and promotion value in colorectal tumor screening.

RESUMO

Objective: A phenotypic and gene mutation study was carried out to investigate the molecular mechanism of inherited protein C deficiency in a family with the disorder. Methods: The proband was a 21-year-old male who was admitted to hospital due to swelling of the left lower limb for 3 months and hemoptysis with chest tightness for more than 1 week. The clinical diagnosis was pulmonary embolism and deep vein thrombosis of the left lower limb. Plasma protein C activity, protein S activity and antithrombin Ⅲ activity were detected in the patient and their family members. Whole exon sequencing was used to analyze a total of 199 genes associated with thrombus susceptibility of the patient. After the mutation was found and Sanger sequencing was used to verify whether the family members carried the same gene mutations as the patient. The conservation of amino acid mutation sites was analyzed by using the software ClustalX-2.1-win. The damage of mutations to protein function was analyzed by PROVEAN and PolyPhen-2 online bioinformatics software. Finally, PyMOL 2.3 software was used to analyze the protein model. Results: The patient and four family members all had the identical heterozygous missense mutation c.1019 C>T (p. Thr340Met) in exon 9 of the protein C gene, resulting in various degrees of protein C deficiency. The Thr340 amino acid was discovered to be poorly conserved in seven homologous species after investigation with the clustalx-2.1-win software. P. Thr340Met was found to be a detrimental mutation by both PROVEAN and PolyPhen-2 online bioinformatics program. The mutation of Thr340 to Met340 caused the hydrogen bond between Thr340 and Gln226 to dissolve, changing the spatial arrangement of protein C, which might be the main explanation for the lower protein C activity, according to the protein model. Conclusions: Protein C deficiency in this family was caused by a hybrid missense mutation C. 1019 C>T (p. Thr340Met). Protein C deficiency may present in varying severity among mutation carriers at the same locus of the protein C gene. Whole-exome sequencing may be considered in young patients with spontaneous venous thromboembolism, even if there is no relevant family history.

RESUMO

The role of the brain-gut microbiota axis in functional gastrointestinal diseases has been gradually recognized. According to the ROME IV diagnostic criteria, functional gastrointestinal diseases are classified as diseases caused by abnormal brain-gut interaction. This concept is of great significance to the change of diagnosis and treatment paradigm of functional gastrointestinal diseases. Chronic constipation is the most common functional gastrointestinal disease. The pathogenesis of chronic constipation is closely related to the imbalance of intestinal flora, the abnormality of enteric nervous system and neurotransmitter in brain. Therefore, in the diagnosis and treatment of chronic constipation, enough attention should be paid to the concept of integration of brain-gut microflora axis, but the clinical application of brain-gut microflora axis is still limited. This may be one of the factors for high incidence but poor treatment efficacy of chronic constipation. Based on the global research progress and our clinical experience, this article expounds the clinical significance of the brain-gut microbiota axis in chronic constipation.

RESUMO

Objective: To explore the application effects of bundle nursing of citric acid extracorporeal anticoagulation on continuous renal replacement therapy (CRRT) of severe burn patients. Methods: A non-randomized controlled study was conducted. Forty-six patients who met the inclusion criteria and received regular nursing of citric acid extracorporeal anticoagulation during CRRT in the First Affiliated Hospital of Army Medical University (the Third Military Medical University) from January to December 2017 were included in regular nursing group (30 males and 16 females, aged 42.0 (38.7,47.0) years, performed with 201 times of CRRT), and 48 patients who met the inclusion criteria and received bundle nursing of citric acid extracorporeal anticoagulation during CRRT in the same affiliation from January to December 2018 were included in bundle nursing group (32 males and 16 females, aged 41.0 (36.0,46.0) years, with 164 times of CRRT). The clinical data of all the patients in the two groups were recorded, including the length of intensive care unit (ICU) stay, total cost of treatment in ICU, cost of CRRT, unplanned ending of treatment, ending of treatment due to operation (calculating the rates of unplanned ending of treatment and ending of treatment due to operation), times of filter service time>24 h, times of CRRT, and filter service life. For the patients in the two groups who continuously received CRRT for 3 days or more from the first treatment, the prothrombin time (PT), activated partial thromboplastin time (APTT), international normalized ratio (INR), total calcium, ionic calcium (calculating the difference of total calcium and ionic calcium between before and after treatment), creatinine, urea, ß2 microglobulin, cystatin C, mean arterial pressure, pH value, oxygenation index, bicarbonate radical, and lactic acid before the first treatment (hereinafter referred to as before treatment) and 3 days after the first treatment (hereinafter referred to as after 3 days of treatment). The treatment-related complications of all patients in the two groups were recorded during hospitalization. Data were statistically analyzed with independent sample t test, Mann Whitney U test, and chi-square test. Results: Compared with those in regular nursing group, the length of ICU stay was significantly shortened (Z=-4.71, P<0.01), the total cost of treatment in ICU was significantly reduced (t=-1.39, P<0.01), the cost of CRRT had no significant change (P>0.05), the rates of unplanned ending of treatment and ending of treatment due to operation were both significantly decreased (with χ2 values of 12.20 and 17.83, respectively, P<0.01), the times of filter service time>24 h was increased significantly (Z=-5.93, P<0.01), the times of CRRT were significantly reduced (Z=-4.75, P<0.01), and the filter service life was significantly prolonged (Z=-9.24, P<0.01) among patients in bundle nursing group. Thirty-one patients in bundle nursing group and 28 patients in regular nursing group continuously received CRRT for 3 days or more from the first treatment. Before treatment, PT, APTT, and INR of patients in bundle nursing group were 24.10 (16.08, 39.20) s, 38.81 (32.32, 45.50) s, and 1.17 (1.12, 1.19), respectively, similar to 31.75 (22.99, 40.96) s, 41.82 (35.05, 48.06) s, and 1.15 (1.11, 1.19) of patients in regular nursing group (P>0.05); the levels of total calcium and ionic calcium of patients in the two groups were similar (P>0.05). After 3 days of treatment, PT, APTT, and INR of patients in bundle nursing group and regular nursing group were 29.06 (20.11, 39.46) s, 35.25 (30.06, 40.28) s, 1.13 (1.09, 1.17) and 36.51 (26.64, 42.92) s, 39.89 (34.81, 46.62) s, 1.14 (1.10, 1.18), respectively, similar to those before treatment (P>0.05); the levels of total calcium and ionic calcium of patients in bundle nursing group were both significantly higher than those before treatment (with Z values of -3.55 and -3.69, respectively, P<0.01); compared with those in regular nursing group, APTT of patients was significantly shorter (Z=-2.29, P<0.05), while the total calcium level of patients was significantly higher in bundle nursing group (Z=-2.26, P<0.05). The difference of total calcium between before and after treatment of patients in bundle nursing group was significantly higher than that in regular nursing group (Z=-3.15, P<0.01). The differences of ionic calcium between before and after treatment of patients in the two groups were similar (P>0.05). Before treatment, the level of ß2 microglobulin of patients in bundle nursing group was significantly higher than that in regular nursing group (Z=-2.84, P<0.01), the platelet count of patients in bundle nursing group was significantly lower than that in regular nursing group (Z=-2.44, P<0.05), while the levels of creatinine, urea, cystatin C, mean arterial pressure, pH value, oxygenation index, bicarbonate radical, and lactic acid of patients in the two groups were similar (P>0.05). After 3 days of treatment, the levels of creatinine, urea, ß2 microglobulin, cystatin C, pH value, bicarbonate radical, and lactic acid of patients were all significantly lower than those before treatment (with Z values of -2.10, -2.90, -3.11, -2.02, -2.34, -2.63, and -2.84, respectively, P<0.05 or P<0.01), while the levels of platelet count, oxygenation index, and mean arterial pressure of patients were all significantly higher than those before treatment in bundle nursing group (with Z values of -6.65 and -2.40, respectively, t=-9.97, P<0.05 or P<0.01); the levels of creatinine, urea, ß2 microglobulin, cystatin C, platelet count, pH value, bicarbonate radical, and lactic acid of patients were all significantly lower than those before treatment (with Z values of -5.32, -2.31, -2.41, -2.21, -3.68, -2.93, -2.20, and -2.31, respectively, P<0.05 or P<0.01), while the oxygenation index and mean arterial pressure of patients were both significantly higher than those before treatment in regular nursing group (Z=-5.59, t=-7.74, P<0.01). After 3 days of treatment, compared with those in regular nursing group, the levels of creatinine, cystatin C, platelet count, oxygenation index, bicarbonate radical, and mean arterial pressure of patients were all significantly higher (with Z values of -2.93, -1.99, -6.39, -2.09, and -2.52, respectively, t=-3.28, P<0.05 or P<0.01), while the levels of urea, ß2 microglobulin, pH value, and lactic acid of patients were all significantly lower in bundle nursing group (with Z values of -3.87, -2.58, -4.24, and -2.75, respectively, P<0.05 or P<0.01). There were no treatment-related bleeding events or hypernatremia related to citric acid treatment of patients in the two groups. The ratio of total calcium to ionic calcium in one patient in bundle nursing group was >2.5, but there was no manifestation of citric acid accumulation poisoning; 1 patient had low ion calcium, and 1 patient had severe metabolic alkalosis, both of which were transient. Five patients had low ion calcium and 2 patients had transient severe metabolic alkalosis in regular nursing group. Conclusions: The implementation of bundle nursing of citric acid extracorporeal anticoagulation during CRRT for severe burn patients shortens the length of ICU stay, reduces the total cost of treatment in ICU and the occurrence of treatment complications, relieves the economic burden of patients, and improves the continuity and quality of treatment.

RESUMO

Unveiling physical phenomena that generate controllable structural coloration are at the center of significant research efforts due to the platform potential for the next generation of printing, sensing, displays, wearable optoelectronics components, and smart fabrics. Colors based on e-beam facilities possess high resolutions above 100K DPI, but limit manufacturing scales up to 4.37 cm2 , while requiring rigid substrates that are not flexible. State-of-art scalable techniques, on the contrary, provide either narrow gamuts or small resolutions. A common issue of current methods is also a heterogeneous resolution, which typically changes with the color printed. Here we demonstrate a structural coloration platform with broad gamuts exceeding the red, green, and blue (RGB) spectrum in inexpensive, thermal resistant, flexible and metallic-free structures at constant 101600 DPI (at the diffraction limit), obtained via mass-production manufacturing. This platform exploits a previously unexplored physical mechanism, which leverages the interplay between strong scattering modes and optical resonances excited in fully three-dimensional dielectric nanostructures with suitably engineered longitudinal profiles. The colors obtained with this technology are scalable to any area, demonstrated up to the single wafer (4-inch). These results open real-world applications of inexpensive, high-resolution, large-scale structural colors with broad chromatic spectra. This article is protected by copyright. All rights reserved.

RESUMO

Objective: To explore the morbidity, mortality, median onset time, clinical characteristics, diagnosis, treatment, and outcome of BK virus (BKV) central nervous system infection in children with allogeneic hematopoietic stem cell transplantation (allo-HSCT) , and improve the understanding, clinical diagnosis, and treatment of the disease. Methods: Seven hundred and nine children who received haploid HSCT treatment in Peking University People's Hospital from January 1, 2015 to December 31, 2020 were reviewed. Fourteen patients were diagnosed with BKV central nervous system infection, and their clinical characteristics, treatment process, and prognosis were analyzed. Results: The incidence of BKV central nervous system infection was 1.97% (14 cases) , mostly in men (12 cases) , with a median age of 11 years old and median onset time of 55 d. Additionally, most of the cases showed disturbance of consciousness and seizures (seven cases) . Furthermore, 14 cases were treated with acyclovir and ganciclovir alone or with gamma globulin. Nine cases were cured, of which one died of viral encephalitis and four of other diseases, with a mortality rate of 35.7%. Conclusion: Individuals with central nervous system involvement by BKV infection, usually show signs and symptoms of acute encephalitis, with some cases being accompanied by meningeal involvement. Although BKV encephalitis was diagnosed and actively treated with drugs, many patients still died of multiple organ failure or other complications. Therefore, when there are neurological symptoms and hemorrhagic cystitis in patients with allo-HSCT, it is necessary to be highly vigilant against BKV central nervous system infection. This helps to make clear diagnosis and treatment quickly; thus, improving the survival rate and quality of life of patients with HSCT.

RESUMO

Objective: To explore the serum cyclic polypeptide biomarkers for ovarian cancer diagnosis. Methods: A total of 54 patients with epithelial ovarian cancer confirmed by pathology in Cancer Hospital, Chinese Academy of Medical Sciences from March 2018 to September 2018 were selected as the study subjects, and 40 healthy women with normal examination results in the cancer screening center were selected as the control. All of the samples were randomly divided into training set and validation set at the ratio of 1∶1 with a random number. Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) combined with magnetic bead technology was used for detecting peptide profiling in serum samples to screen significantly differently expressed peptides between ovarian cancer group and control group of the training set (score>5). Receiver operating characteristic (ROC) curve analysis was used to screen differential peptide peaks with area under curve (AUC) ≥0.8, sensitivity and specificity>90% in the training set and validation set. Liquid chromatography-mass spectrometry (LC-MS/MS) was further used to determine the composition of differentially expressed peptides. Results: By comparing the peptide profiles of the two groups, 102 differential peptide peaks were initially detected in the mass-to-charge ratio range of 1 000 to 10 000. ROC curve analysis showed that there were 42 differential peptide peaks with AUC ≥0.8 in both training set and validation set, 19 of which were highly expressed in ovarian cancer group, and 23 were lowly expressed. There were 15 different peptide peaks in highly expressed ovarian cancer group with sensitivity and specificity over 90%. The mass-to-charge ratios were 7 744.27, 5 913.41, 5 329.87, 4 634.21, 4 202.02, 3 879.26, 3 273.35, 3 253.79, 3 234.34, 2 950.33, 2 664.51, 2 018.38, 1 893.37, 1 498.69 and 1 287.55. There were 15 different peptide peaks in lowly expressed ovarian cancer group with sensitivity and specificity over 90%, the mass-to-charge ratios were 9 288.46, 7 759.77, 5 925.24, 4 652.77, 4 210.42, 3 887.02, 3 279.90, 3 240.82, 2 962.15, 2 932.70, 2 022.42, 1 897.16, 1 501.69, 1 337.38 and 1 290.13. No protein composition was identified in 15 different peptide peaks in lowly expressed ovarian cancer group. The two protein compositions identified in 15 different peptide peaks in highly expressed ovarian cancer group were recombinant serglycin (SRGN) and fibinogen alpha chain (FGA), the mass-to-charge ratios of which were 1 498.696 and 5 913.417, respectively. The sensitivity and specificity of the two proteins for ovarian cancer diagnosis were 100%, 100% and 90.9%, 100%, respectively. Conclusion: SRGN and FGA are highly expressed in the serum of ovarian cancer patients, which may be potential diagnostic markers for ovarian cancer.

RESUMO

Objective: To analyze the prognostic factors of breast cancer patients with isolated chest wall recurrence (ICWR) after mastectomy, and investigate the optimal treatment. Methods: A total of 201 breast cancer patients with ICWR after mastectomy who were treated in Cancer Hospital, Chinese Academy of Medical Sciences and the Fifth Medical Center Chinese PLA General Hospital from October 1998 to April 2018 were retrospectively analyzed. The median follow-up was 92.8 months and survival data were obtained. Results: Among 201 patients with ICWR, 103 patients developed subsequent locoregional recurrence (sLRR) and 5-year cumulative sLRR rate was 49.1%; 134 patients developed distant metastasis (DM) and 5-year DM rate was 64.4%; 103 patients died, the median progression-free survival (PFS) was 17.4 months and the 5-year PFS rate was 23.2%; the median overall survival (OS) was 62.5 months and the 5-year OS rate was 52.1%. Multivariate analysis showed that the recurrence interval (HR=2.17, 95% CI: 1.26-3.73) and the locoregional treatment (HR=1.59, 95% CI: 1.05-2.40) were the independent prognostic factors for sLRR. The initial HER2 status (HR=1.60, 95% CI: 1.03-2.48) was the independent prognostic factor for DM. The recurrence interval (HR=1.99, 95% CI: 1.30-3.04), the locoregional treatment (HR=1.99, 95% CI: 1.43-2.76) and the treatment modalities after recurrence (HR=1.70, 95% CI: 1.18-2.46) were the independent prognostic factors for PFS. The initial HER2 status (HR=1.69, 95% CI: 1.02-2.81), the recurrence interval (HR=1.85, 95% CI: 1.15-2.98) and the treatment modalities after recurrence (HR=2.48, 95% CI: 1.56-3.96) were the independent prognostic factors for OS. Conclusions: Breast cancer patients after ICWR have an optimistic OS until now, but the risk of sLRR and DM is high. Comprehensive treatment modalities including surgery, radiotherapy and systemic therapy improve the outcome of breast cancer patients with ICWR after mastectomy.

RESUMO

Objective: To observe the application effects of a standard communication system-based continuous home remote visit mode in the management of visits to severely burned patients in the post-pandemic era of coronavirus disease 2019 (hereinafter referred to as post-pandemic era). Methods: A retrospective cohort study was conducted. A total of 69 severely burned patients who met the inclusion criteria and were admitted to the First Affiliated Hospital of Army Medical University (the Third Military Medical University) from February to December, 2020 and their 69 family members were recruited into this study. According to the difference of visit model, 33 severely burned patients who were admitted into burn intensive care unit (BICU) from February to June, 2020 and received completely restricted visits according to the requirements for epidemic prevention and control and their corresponding 33 family members were included into conventional visit group; 36 severely burned patients who were admitted into BICU from July to December, 2020 and received the standard communication system-based continuous home remote visits and their 36 corresponding family members were recruited into remote visit group. The family members in conventional visit group could only communicate with the primary nurses by telephone, while the patients and family members in remote visit group could communicate with the primary nurses, responsible doctors, rehabilitation therapists, and nutrition therapists through WeChat video call. The survey results of general information questionnaire and Hamilton Anxiety Scale (HAMA) scores of two groups of patients and their family members at BICU admission of patients, HAMA scores of the two groups of patients and their family members in the second week of BICU admission and at discharge from BICU of patients, the scores of the Visiting Effect Evaluation Scale of the two groups of patients and their family members and the scores of Chinese version of Critical Care Family Satisfaction Survey (C-CCFSS) of the two groups of family members at discharge from BICU, and the scores of Satisfaction Survey and Evaluation Scale During Hospitalization of patients within the first week after the discharge of patients from BICU were compared. Data were statistically analyzed with chi-square test, Fisher's exact probability test, and Mann-Whitney U test. Results: In remote visit group, there were 29 males and 7 females in patients, aged 48 (34, 53) years, and 15 males and 21 females in family members, aged 45 (30, 48) years. In conventional visit group, there were 24 males and 9 females in patients, aged 49 (38, 54) years, and 9 males and 24 females in family members, aged 44 (35, 48) years. At BICU admission of patients, the HAMA scores of the two groups of patients and family members were both similar (P>0.05). The total HAMA scores of patients and family members in remote visit group were significantly lower than those in conventional visit group in the second week when the patients were admitted to BICU (Z=-3.195, -3.018, P<0.01) and discharged from BICU (Z=-2.118, -2.380, P<0.05). At discharge from BICU of patients, the scores of each dimension in Visiting Effect Evaluation Scale of the patients in the two groups were similar (P>0.05); while scores of 3 dimensions including patient safety information, diagnosis and treatment quality information, and psychological support information in Visiting Effect Evaluation Scale of family members in remote visit group were significantly higher than those in conventional visit group (Z=-2.372, -2.209, -2.174, P<0.05), and only the scores of visit perception of family members were close to those in conventional visit group (P>0.05). At discharge from BICU of patients, the C-CCFSS scores of the family members in remote visit group was 99 (98, 108), which were significantly higher than 98 (97, 100) in conventional visit group (Z=-2.545, P<0.05). Within the first week after the discharge of patients from BICU, the scores of Satisfaction Survey and Evaluation Scale During Hospitalization of patients in remote visit group were 99 (98, 100), which were significantly higher than 96 (94, 98) in conventional visit group (Z=-5.213, P<0.01). Conclusions: In the management of visits to severely burned patients in the post-pandemic era, application of the standard communication system-based continuous home remote visit mode can improve the visit effect and satisfaction, and effectively alleviate the anxiety of patients and their family members.

RESUMO

Objective: To investigate the influence of HBV infection on the prevalence of fatty liver disease in Jinchang cohort and provide theoretical evidence for the prevention and treatment of fatty liver disease. Methods: Epidemiological investigation, laboratory examination and abdominal ultrasound were conducted in the baseline population of Jinchang cohort to collect the basic data, the differences in the prevalence of fatty liver disease under different HBV infection patterns were described and compared and the influence of different HBV infection patterns on the prevalence of fatty liver disease were evaluated by using logistic regression analysis. Results: The baseline Jinchang cohort population totaled 45 605, including 27 917 males and 17 688 females. The male to female ratio was 1.6∶1. The mean age of the overall population was 46.49 years. Among the 8 common HBV infection modes in the Jinchang cohort, the prevalence of fatty liver was low in HBsAg, HBeAg and HBcAb positive, HBsAg and HBcAb positive, and HBsAg, HBeAb and HBcAb positive groups. For 4 serum markers of HBV infection, the prevalence of fatty liver disease in HBsAg and HBeAg positive groups was lower than that in HBsAg and HBeAg negative groups. Logistic regression analysis showed that being HBsAg and HBcAb positive (OR=0.61, 95%CI: 0.39-0.98) and HBsAg, HBeAg and HBcAb positive (OR=0.52, 95%CI: 0.30-0.89) could reduce the risk for fatty liver disease. Conclusion: Acute HBV infection reduces the prevalence of fatty liver disease, and the reason may be related to the disturbance of the body's fat metabolism by active HBV replication.

RESUMO

Objective: To explore the influencing factors for non-alcoholic fatty liver disease (NAFLD) in Jinchang cohort, and provide scientific basis for the prevention and control of NAFLD. Methods: A total of 20 051 patients without fatty liver at baseline survey and met the inclusion criteria in Jinchang cohort were selected as study subjects. Prospective cohort study and Cox regression analysis were used to investigate the influencing factors for NAFLD, and the dose-response relationship between related biochemical indicators and NAFLD risk was studied by restricted cubic spline method. Results: The incidence of NAFLD was 42.37/1 000 person years. Multivariate Cox regression analysis showed that being worker and technical personnel (being worker:HR=0.84,95%CI:0.70-0.99;being technical personnel:HR=0.73,95%CI:0.56-0.95), tea drinking (current drinking:HR=0.86,95%CI:0.78-0.94;previous drinking: HR=0.52,95%CI: 0.31-0.86), exercise (occasionally: HR=0.79, 95%CI: 0.68-0.91;frequently:HR=0.60,95%CI:0.52-0.69), low body weight (HR=0.10, 95%CI: 0.05-0.22), daily intake of dairy products >300 ml/day (HR=0.78, 95%CI: 0.71-0.87) and HBV infection (HR=0.77, 95%CI: 0.60-0.99) were the protective factors for NAFLD, while being internal or office workers (HR=1.84, 95%CI: 1.46-2.31), income ≥2 000 yuan (2 000- yuan: HR=1.32, 95%CI: 1.04-1.66; ≥5 000 yuan: HR=1.72, 95%CI:1.11-2.66), bachelor degree or above (HR=1.35,95%CI:1.03-1.76), overweight (HR=2.31, 95%CI:2.08-2.55), obesity (HR=3.95, 95%CI: 3.42-4.56), impaired fasting blood glucose (HR=1.31, 95%CI:1.17-1.47), diabetes (HR=1.53, 95%CI: 1.30-1.80), increased TC (HR=1.37,95%CI:1.24-1.52), increased TG (HR=1.79,95%CI: 1.62-1.98), decreased HDL-C (HR=1.29, 95%CI: 1.14-1.45), increased ALT (HR=1.13, 95%CI: 1.01-1.26) and high-fat diet (HR=1.24, 95%CI: 1.11-1.40) were the risk factors for NAFLD. Moreover, TC, TG, HDL-C, ALT and FPG all showed good dose-response relationship with the incidence of NAFLD. Conclusion: Occupation, education level, income level, tea drinking, exercise, BMI, FPG, blood lipid, ALT, HBV infection and diet were related to the incidence of NAFLD.

RESUMO

One of the most common birth defects is cleft palate only (CPO) of which non-syndromic cleft palate only (NSCPO) accounts for 50%. NSCPO is a complex disease where multiple genes and environmental factors contribute to its risk. Unlike non-syndromic cleft lip with or without cleft palate (NSCL/P), previous genome-wide association studies only identified a few common genetic variations achieving genome-wide significance. This review summarizes the recent findings on genetic epidemiology of NSCPO. According to the current evidence, the candidate genes are divided into three categories: candidate genes with strong evidence, candidate genes with suggestive evidence, and candidate genes with inadequate evidence. The findings of epigenetic studies, the next generation sequencing studies, interaction analysis on NSCPO are also reviewed.

RESUMO

The cohort study of lung cancer in high-risk population in communities in China was a part of Lung Cancer Cohort Study initiated in 2017 and funded by Precision Medicine Research of National Key Research and Development Program. Around 50 000 participants from the communities were enrolled from 7 cities in 7 regions in China. Information about the risk factors for lung cancer were collected and the populations at high risk for lung cancer were identified. Then, low-dose CT (LDCT) screening of lung cancer was conducted in the populations at high risk, and further information about the diagnosis of lung cancer cases and death cases were collected. Therefore, a community population-based cohort was established for lung cancer risk factor exposure survey, high risk population evaluation, LDCT screening and lung cancer case and death follow up. Meanwhile, biological samples were collected from all the participants in the cohort to support the future precision medicine research of lung cancer.

RESUMO

Objective: To analyze the mortality in HIV/AIDS cases aged ≥15 years under antiretroviral treatment (ART) in Henan province from 2002 to 2019, and provide evidence for reducing the mortality rate of HIV/AIDS and AIDS prevention and treatment. Methods: Data of HIV/AIDS cases aged ≥15 years who received ART in Henan from 2002 to 2019 were obtained from "Infectious Disease Surveillance System - Basic Information on AIDS Prevention and Control". In this retrospective study, Cox proportional risk model was used to analyze the influencing factors for HIV/AIDS related deaths. Software SPSS 23.0 was used for statistical analysis. Results: From 2002 to 2019, a total of 72 986 HIV/AIDS cases aged ≥15 years received ART, in whom, 16 634 died during this period. Most of the death cases were aged ≥40 years old (68.5%,11 393/16 634), males (62.6%,10 419/16 634), infected through blood-borne transmission (71.7%,11 927/16 634), and farmers or migrant workers (91.7%,15 249/16 634). Most of the deaths were due to AIDS related diseases (73.7%, 12 261/16 634), and the case fatality rate was 16.8% (12 261/72 986). A total of 34.6% (4 237/12 261) of HIV/AIDS cases died of AIDS-related diseases in the first year of ART, and the cumulative survival rates at 10 and 18 years of ART were 78.3% and 71.8%, respectively. The proportion of the HIV/AIDS cases with baseline CD4+T lymphocyte (CD4) counts <200 cells/µl at age 15 years when ART started was 45.5% (30 432/66 898). Cox proportional risk regression model showed that, compared with the cases with baseline CD4 counts ≥350 cells/µl, the risk of death was 1.78 times higher than in the cases with CD4 counts <200 cells/µl (95%CI: 1.64-1.94) and 1.24 times higher in the cases with CD4 counts ≥200 cells/µl (95%CI: 1.13-1.36), respectively. The risk of death in symptomatic cases at baseline survey was 1.25 times higher than that in asymptomatic cases (95%CI: 1.16-1.35). The cases with a latest viral load ≥1 000 copies/ml had 7.09 times higher risk of death than those with a last viral load<1 000 copies/ml (95%CI: 6.65-7.54). Conclusions: The majority of HIV/AIDS deaths occurred in the cases aged ≥15 years receiving ART in Henan province during 2002-2019, who were infected through blood-borne transmission and farmers/migrant workers, and AIDS-related diseases were the main causes of the deaths. With the gradual implementation of ART policy, the high survival rate in HIV/AIDS cases can be maintained for a long time in Henan. To reduce the case fatality rate and improve the quality of life of HIV/AIDS patients, CD4 counts test should be further strengthened and eligible HIV/AIDS patients should be covered by standard ART in a timely manner.

RESUMO

Objective: To analysis the characteristics and trends of non-martial and non-commercial heterosexual transmission of HIV/AIDS cases in Henan province between 2015 and 2020. Methods: Information of newly reported HIV/AIDS through non-martial and non-commercial heterosexual transmission was collected from National Comprehensive HIV/AIDS Information system, using SPSS 22.0 to analyze the characteristics and tend of cases. Results: During 2015-2020, a total of 10 877 HIV/AIDS cases infected by non-martial and non-commercial heterosexual transmission were newly reported in Henan province. This mode of infection increased from 32.6% in 2015 to 35.5% in 2020 (trend χ2=81.880,P<0.01). The male to female ratio was 1.9∶1 (7 105∶3 772). The mean age was (45.5±15.8) years, increasing annually (F=5.184,P<0.01). For female cases, the proportion of aged 15-50 years group was decreased annually (trend χ2=69.888, P<0.01). Most HIV/AIDS cases were distributed in the early HIV epidemic areas and Zhengzhou city, the same as the cases of the first CD4+T cells counts (CD4) below 200 cells/µl. The median (P25, P75) first CD4 count was 298 (143, 462) cells/µl. The proportion of the first CD4<200 cells/µl was no significant change annually, while the proportion of the first CD4≥500 cells/µl was decreasing annually (trend χ2=18.961,P<0.01). Conclusions: The reported cases through non-martial and non-commercial heterosexual transmission increased, with most of them were male, married, junior, farmer, migrant laborer, and aged 40-59 years. It is needed to focus on the rural district and the middle-aged population, combined with biological and social factors to control the prevalence of AIDS through comprehensive prevention and control measures.

RESUMO

Objective: To evaluate the effect of quantitative analysis of optical signal in the near infrared fluorescence molecular navigation surgery for oral squamous cell carcinoma (OSCC). Methods: SCC9, HSC3 and epithelial cell lines (Leuk-1) were co-cultured with indocyanine green (ICG) for 6 hours in vitro in order to verify whether the quantitative analysis of near infrared optical signal could distinguish tumor cells from normal cells. A total of 16 BALB/c male mice (5-6 weeks, 20-25 g) were selected and fed in clean grade equipment and were equally divided into two groups. SCC9 and HSC3 cells were inoculated into the back of each mouse at a concentration of 1×106 cells/ml to establish a subcutaneous graft tumor model. The 5 mg/kg ICG was injected into the caudal vein to each of the tumor bearing mouse and the difference between OSCC and normal tissues was then analyzed by near infrared optical signal quantitative analysis (Paired t test). Ten patients with OSCC were enrolled in the Department of Stomatology of the First Affiliated Hospital of Bengbu Medical College from November 2019 to July 2020, including 6 patients with tongue squamous cell carcinoma and 4 patients with buccal squamous cell carcinoma.The patients were 6 males and 4 females and the range of age was from 46 to 71 years with an average age of 58.6 years. These patients were injected ICG (0.75 mg/kg) via the cubital vein at 6-8 h before surgery. Intraoperatively, the fluorescence intensities (FI) of near infrared signal were measured at tumor, peritumor tissues (2.0 cm beyond the tumor boundary) and normal tongue or buccal mucosa respectively. The signal background ratios (SBR) from the three site groups were assessed using one-way ANOVA followed by the Tukey post hoc test for multiple comparisons. Results: In vitro, the levels of near infrared FI in HSC3 and SCC9 groups were higher than that in Leuk-1group (P<0.01). In vivo, the result showed that the SBR of OSCC and normal tissues was 8.67±0.35. Clinical studies showed that the intensity of tumor [(408.23±101.51) arbitrary units (AU)] was significantly higher than those of peritumoral [(253.12±64.89) AU] and normal tissues [(261.50±80.47) AU] respectively. The SBRs of near infrared FI of tumor and peritumoral tissues, tumor and normal tissues were 1.61±0.53 and 1.56±0.48 respectively, while that of peritumoral and normal tissues was 0.96±0.17. Conclusions: The quantitative analysis of near infrared optical signal could distinguish OSCC from normal cells and could locate the OSCC tissue intraoperatively. Optical signal quantification and ICG near infrared fluorescence molecular technology possessed the feasibility in primary OSCC resection.

RESUMO

Objective: Based on the genetic diagnosis and follow-up study on pediatric neurofibromatosis 1 (NF1) patients, interrogating the genotype-phenotype correlations of patients with NF1 mutations. Methods: 32 Patients from age of 2 months to 5 years old (17 male and 15 female) suspected for neurofibromatosis 1 were recruited during September 2016 to January 2018 in Shanghai Children's Medical Center retrospectively. Genetic diagnosis was applied to detect pathogenic variants. Long-term follow-up study were conducted to reveal progress of the disease and genotype-phenotype correlations. Results: 27 patients were detected with pathogenic NF1 variants, among them three were not reported. 3 patients inherited pathogenic variants from their NF1 diagnosed parents, all the other variants were de novo. Progressive development of phenotypes wasn't observed in most patients during the follow-up (14/27). Some patients were diagnosed with short stature, pulmonary artery stenosis and developmental delay during the follow-up(7/27). Short stature and pulmonary artery stenosis may be associated with missense mutation and severe truncation mutation of NF1 gene, respectively. Conclusions: Genetic diagnosis is required in young patients of NF1.Follow-up plan of pediatric patients should be adjusted based on genetic findings. Early follow-up of cardiovascular abnormalities should be noted in patients with missense mutation. Height development in patients with severe truncating variants are needed.
