[A multi-dimensional analysis of pollen broadcasting concerns in Chinese population: a large-scale multi-center cross-sectional survey].

Objective: To investigate the concern about pollen broadcasting in Chinese population from multiple dimensions and to understand the information about allergic rhinitis (AR) in China by analyzing related factors. Methods: From March 1 to September 30, 2022, a large-scale multi-center cross-sectional survey was conducted based on the Questionnaire Star platform in 21 Chinese hospitals. A total of 7 056 subjects from 7 regions in China: Northeast, North, East, Central, South, Southwest, and Northwest China were included. Basic characteristics (including social demographic characteristics and disease characteristics of AR patients), concern about pollen broadcasting, the willingness of pollen-induced AR (PiAR) patients to receive pollen broadcasting, and the treatment satisfaction rate of AR patients were collected. The chi-square test, multivariate linear regression model, and Logistic regression analysis were used to analyze the concern about pollen broadcasting in the Chinese population and related factors from multiple dimensions. Results: Among 7 056 subjects, 23.02% were concerned about pollen broadcasting. Among 3 176 self-reported AR and 1 019 PiAR patients, 25.60% and 39.16% were concerned about pollen broadcasting, respectively, which was higher than that of non-AR or non-PiAR subjects (χ2 value was 21.74 and 175.11, respectively, both P<0.001). Among AR patients, the proportion of spring and autumn allergen-positive patients concerned about pollen broadcasting was higher than that in perennial allergen-positive patients (χ2 value was 20.90 and 19.51, respectively, both P<0.001). The proportion of AR patients with asthma, sinusitis, allergic conjunctivitis, and cardiovascular and cerebrovascular diseases was higher than those without complications (χ2 value was 50.83, 21.97, 56.78, 7.62, respectively, all P<0.05). The proportion of AR patients in North China who could find pollen broadcasting locally was 31.01%, significantly higher than those in other regions (all P<0.05). Multivariate linear regression model analysis showed that among PiAR patients, those with higher per capita household income and higher AR disease cognition levels had been concerned about pollen broadcasting in the past, and those complicated with allergic conjunctivitis had stronger intention to receive pollen broadcasting (B value was 0.24, 0.13, 0.66, 0.47, respectively, all P<0.05). The higher the disease cognition level of PiAR patients, the stronger their willingness to actively participate in treatment (R2=0.72, P<0.001). Only 18.89% of AR patients felt satisfied with the treatment effect. Logistic regression analysis showed that in AR patients, the treatment satisfaction rate was significantly higher among those concerned about pollen broadcasting compared to those who were not (OR=1.83, P<0.001). Conclusions: Currently, the dissemination of pollen broadcasting in China is hindered by various factors such as disease cognition level. The treatment satisfaction among AR patients remains unsatisfactory.

[The rise and fall of the leprosy clinic in Ru Gao in the North of Jiangsu in the period of the Republic of China].

The North of Jiangsu was a traditional area for leprosy in Chinese history. In the period of the Republic of China, one of the largest leprosy clinics in China was established in Ru Gao (Jugao) with the help of Chinese and foreign charitable organizations, the Chinese central government and some squires. It was the only large clinic for leprosy in the North of Jiangsu. It was officially opened in 1924, attached to the Presbyterian Church hospital, and was closed in 1927 after the breakout of the civil war. It reopened in May 1933, hosted by a leprologist, Lee S. Huizenga. Ru Gao (Jugao) leprosy clinic treated around 1,000 lepers in the North of Jiangsu with medicines and language communication. The establishment of the leprosy clinic made a historical contribution in terms of preventing leprosy from spreading to Shanghai. It closed in the spring of 1938 because of the invasion of the Japanese military.

[Correlation analysis between prenatal exposure of per-/polyfluoroalkyl compounds and neonatal outcome].

Objective: To investigate the correlation between the prenatal exposure of per-/polyfluoroalkyl substances (PFASs) and the neonatal outcome. Methods: A total of 506 maternal infant cohort samples were collected in Hangzhou, Zhejiang province from 2020 to 2021. The exposure levels of seven PFASs in maternal serum before delivery were detected by solid-phase extraction-ultra performance liquid chromatography tandem mass spectrometry. Multivariable linear regression model was used to analyze the influence of prenatal exposure of PFASs on birth weight, birth length and Apgar score. Results: The maternal age, prenatal body mass index and gestation age were (31.3±4.3) years old, (26.7±3.2) kg/m2 and (265.0±28.3) days, respectively. The birth weight, birth length and scores of Apgar-1 and Apgar-5 were (3.1±0.8) kg, (49.3±2.9) cm, (9.88±0.47) points and (9.99±0.13) points, respectively. PFASs were widely distributed in maternal serum, with the highest concentration of (18.453±19.557) ng/ml, (6.756±9.379) ng/ml and (5.057±8.555) ng/ml for perfluorooctanoic acid (PFOA), perfluorooctane sulfonate (PFOS) and 6∶2 chlorinated polyfluorinated ether sulfonate (Cl-PFESA), respectively. Maternal age, parity and delivery mode were associated with the exposure level of PFASs (P<0.05). Subgroup analysis showed that PFOS had negative effects on birth weight (ß=-0.958), birth length (ß=-0.073) and Apgar-5 score (ß=-0.288) for neonates in the low birth weight (LBW) group. 6∶2 Cl-PFESA and 8∶2 Cl-PFESA inhibited the birth weight (ß=-0.926; ß=-0.552) and length (ß=-0.074; ß=-0.045) of newborn in the LBW group. In addition, 4∶2 fluorotelomer sulfonate (FTS) was associated with increased birth weight (ß=0.111) and decreased Apgar-5 score (ß=-0.030) in the normal weight group. Conclusion: Prenatal exposure to PFASs is associated with birth weight, birth length and Apgar-5 score. It is necessary to continue to pay attention to the impact of PFASs on fetal growth and development through maternal-fetal transmission.

[Analysis of the efficacy of transnasal endoscopic annulus of zinn area decompression in the treatment of dysthyroid optic neuropathy].

Objective: To evaluate the early efficacy and safety of transnasal endoscopic decompression in the annulus of zinn (AZ) region for refractory dysthyroid optic neuropathy (DON) and to preliminarily analyze the correlated factors of postoperative visual function outcome. Methods: From July 2021 to January 2023, 35 patients (56 eyes) with DON who received AZ area decompression in Peking University Third Hospital were included retrospectively, including 9 males (13 eyes) and 26 females (43 eyes), aging (52.2±12.0) years. Among them, 35 eyes underwent two-wall (medial and inferior) orbital decompression using an endonasal endoscopic approach, while 21 eyes received three-wall (medial, lateral, and inferior) orbital decompression through a combined approach. Key parameters such as best corrected visual acuity (BCVA), visual field (MD value), eyeball prominence, intraocular pressure, and complications were recorded. Postoperative data were collected one month after surgery. The statistical analysis was performed using paired t-test and Spearman correlation analysis. Results: Significant outcomes were observed post surgery in BCVA, visual field, intraocular pressure and proptosis (t value was 8.37, 6.17, 4.50, and 9.20, respectively, all P<0.001). The reduction in proptosis was statistically significant between the 2-wall and 3-wall orbital decompression groups (t=-2.82, P=0.007). Changes in BCVA, visual field, and intraocular pressure before and after surgery was greater in the 3-wall orbital decompression group compared to 2-wall orbital decompression group, although the difference was not statistically significant (all P>0.05). Change in postoperative visual acuity and visual field was significantly positively correlated with preoperative visual acuity and preoperative visual field (all P<0.001). Similarly, change in intraocular pressure and proptosis was positively correlated with preoperative intraocular pressure and preoperative protrusion (all P<0.001). Preoperative diplopia was reported in seven patients (20.0%), and two new cases (5.7%) were noted post-operation, which resolved within 3 months after surgery. Conclusions: Endoscopic endonasal decompression of the AZ area is a safe and effective surgical treatment for DON, with notable improvements in BCVA. Furthermore, three-orbital wall decompression seems to yield better outcomes in terms of eye retraction.

[Surgical treatment of papillary thyroid carcinoma involving larynx and trachea].

Objective: To evaluate the efficacy of surgical treatment of papillary thyroid carcinoma (PTC) involving larynx and trachea. Methods: A total of 1 436 cases of thyroid malignant tumors were admitted to the Department of Otolaryngology, Qilu Hospital of Shandong University from 2004 to 2019, including 110 cases of PTC involving larynx and trachea, and of which 105 cases with complete follow-up data were retrospectively analyzed. There were 42 males and 63 females, with a male/female ratio of 1∶1.5, aged from 28 to 81 years. All lesions involved trachea, including 11 cases involving both trachea and larynx. Of those 83 cases underwent laryngeal and airway wall tumor excision, and 22 cases underwent radical tumor excision plus laryngeal and trachea repair. Extubation rate was analyzed and the postoperative survival curve of patients was analyzed by Kaplan-Meier method. Results: Among 105 cases, 16 cases underwent tracheotomy and 12 cases were successfully extubated. The overall 3- 5- and 10-year survival rates were 100.0%, 86.4% and 72.5%, and the disease-free survival rates were 93.1%, 81.6% and 57.7%, respectively. There was significant difference in survival curve between the two groups (χ2=4.21, P=0.040). The 5-year and 10-year survival rates were 94.6% and 77.3% in laryngeal and tracheal tumor exclusion group, and 85.7% and 51.4% in the radical tumor resection group. There was no significant difference in the survival curves between the two groups (χ2=3.50, P=0.061). Conclusion: PTC patients with laryngeal and tracheal involvement can achieve long survival and good quality of life through reasonable surgical treatment.

[Relationship between onco-immunological and morphologic characteristics of lymphoepithelioma-like carcinoma and lymphocyte subtypes of peripheral blood].

Objective: To study the relationship between the onco-immunological and morphologic characteristics of lymphoepithelioma-like carcinoma (LELC) and peripheral blood lymphocyte subtypes and its clinical significance. Methods: The pathologic and clinical data of 117 LELC patients who were admitted to the Tumor Hospital of the University of Chinese Academy of Sciences from 2006 to 2018 were collected. The histological classification was based on previously reported morphological classification method. The onco-immunological and morphologic characteristics of the tumors such as lymphoid follicle formation and interstitial fibrous hyperplasia, patient's peripheral blood lymphocyte subtypes and prognosis data were collected. The relationship between various factors and their impact on prognosis were analyzed. Results: There were 117 patients, including 61 females and 56 males. The male to female ratio was 0.9∶1.0. The age of onset was 24-89 years (median 52 years). Primary sites included head and neck (68 cases), lungs (26 cases), stomach (15 cases), and others (eight cases). Morphologically, 54 cases were type Ⅰ, 62 cases were type Ⅱ, and one case could not be classified. The onco-immunological and morphologic features of the LELC tumors showed a continuous spectrum. Interstitial TILs were noted from focally to diffuse, and the interstitial fibrous tissues were from hardly visible to obvious sclerotic. Formation of lymphoid follicles was seen in 42 patients; obvious fibrosis was seen in 31 cases. Data of peripheral blood lymphocyte subtyping by flow cytometry were available in 73 cases. These data included CD3+total T cells, CD3+CD4+helper T cells, CD3+CD8+cytotoxic T cells, CD3-CD56+natural killer (NK) cells, CD3-CD19+B cells, CD4+CD45RA-T helper induction subgroup, CD4+CD45RA+ T suppression induction subgroup, CD4+CD45RO+memory T cell subgroup, CD45RA+CD45RO+activated T cell subgroup, CD8+CD38+activated cytotoxic T cell, and CD25+lymphocytes and CD44+lymphocyte. The proportion of lymphocytes of each subtype was normal in most patients, but the proportion of CD44+lymphocytes in 61 cases (83.6%) was increased; the proportion of T cell suppression induced subgroups was decreased in 53 cases (72.6%). Correlation analysis found a significant correlation between clinical stage and NK cells (P=0.023); tumor histologic type and cytotoxic T cells were significantly positively correlated (P=0.012); while tumor cell morphologic differentiation was significantly related to total T cells (P=0.003) and NK cells (P=0.026); Formation of interstitial lymphoid follicles was positively correlated with memory T cell subsets (P=0.025); Tumor interstitial fibrosis was significantly positively correlated with T suppression-induced subpopulations (P=0.004), and was significantly negatively correlated with total T cells (P=0.023) and with the expression of CD44 adhesion molecules (P=0.003). Survival analysis found that lymphoid follicle formation was a favorable prognostic factor for LELC (P=0.001). Conclusions: The onco-immunological and morphologic features in LELC show a continuous spectrum; the tumor clinicopathological characteristics and onco-immunological morphology are closely related to peripheral blood T lymphocyte subtypes, and the formation of interstitial lymphoid follicles is a favorable prognostic factor for LELC.

A two-dimensional Sb/InS van der Waals heterostructure for electronic and optical related applications.

Stable configurations with excellent optical adsorption are crucial for photovoltaics or photocatalysis. Two-dimensional materials with intrinsic electric fields have been proposed as suitable for electric and optical devices. Here, we have performed DFT calculations on the electronic and optical properties of a bilayer Sb/InS van der Waals heterostructure, which consists of Sb and InS monolayers, by studying the band structures, charge density difference and distribution. Interestingly, the Sb/InS bilayer exhibits typical type-II band alignment character with a direct energy gap of 0.44 eV, and the electrons and holes are separated on different surfaces. Furthermore, applying an external E-field and biaxial strain is proved to be an effective way to modify the energy gap, the same as the electronic and optical properties. These theoretical predictions pave the way for high performance electronic and optical devices based on new two-dimensional van der Waals structures.

[Pathological features related to onco-immunity and their clinical significance of pancreatic ductal adenocarcinoma].

Objective: To investigate the tumor immunity-related pathologic features and clinical significance in pancreatic ductal adenocarcinoma (PDAC). Methods: All pathologic materials and clinical information of 192 PDAC patients from the Cancer Hospital of the University of Chinese Academy of Sciences from January 2010 to December 2020 were collected. The onco-immune microenvironment associated morphologic features were evaluated, and MHC-Ⅰ, PD-L1, CD3, and CD8 expression were detected by immunohistochemistry (IHC). Then the correlation between the factors and their influence on prognosis was analyzed. Results: There were 163 cases of non-specific adenocarcinoma (163/192, 84.90%), 18 cases of adeno-squamous carcinoma (18/192, 9.37%), and 11 cases of other rare subtypes (11/192, 5.73%). Perineural invasion was observed in 110 cases (110/192, 57.29%) and vascular invasion in 86 cases (86/192, 44.79%). There were 84 cases (84/182, 46.15%) with severe chronic inflammation. Tumor infiltrating immune cell numbers (TII-N) were increased in 52 cases (52/192, 27.08%). Lymphocytes and plasma cells were the main infiltrating immune cells in 60 cases (60/192, 31.25%), whereas in 34 cases (34/192, 17.71%) the tumors were mainly infiltrated by granulocytes, and 98 cases (98/192, 51.04%) showed mixed infiltration. CD3+T cells were deficient in 124 cases (124/192, 66.31%). CD8+T cells were deficient in 152 cases (152/192, 79.58%). MHC-Ⅰ expression was down-regulated in 156 cases (156/192, 81.25%), and PD-L1 was positive (CPS≥1) in 46 cases (46/192, 23.96%). Statistical analysis showed that TII-N was negatively correlated with vascular invasion (P=0.035), perineural invasion (P=0.002), stage (P=0.004) and long-term alcohol consumption (P=0.039). The type of immune cells correlated positively with chronic pancreatic inflammation (P=0.002), and negatively with tumor differentiation (P=0.024). CD8+T cells were positively correlated with CD3+T cells (P=0.032), MHC-Ⅰ expression (P<0.001) and PD-L1 expression (P=0.001), and negatively correlated with long-term smoking (P=0.016). Univariate analysis showed that histological nonspecific type (P=0.013) and TII-N (P<0.001) were the factors for good prognosis. Vascular invasion (P=0.032), perineural invasion (P=0.001), high stage (P=0.003) and long-term alcohol consumption (P=0.004) were adverse prognostic factors. COX multivariate risk analysis found that TII-N was an independent favorable factor for PDAC, while perineural invasion was an independent adverse risk factor. Conclusions: TII-N is an independent superior prognostic factor for PDAC, and significantly correlated with many factors; chronic alcohol consumption and smoking may inhibit onco-immunity in PDAC patients.

Limonitum Ameliorates Castor Oil-Induced Diarrhoea in Mice by Modulating Gut Microbiota.

Diarrhoea is a common clinical condition; its pathogenesis is strongly associated with gut microbiota dysbiosis. Limonitum is a well-known traditional Chinese medicine that exerts appreciable benefits regarding the amelioration of diarrhoea. However, the mechanism through which Limonitum ameliorates diarrhoea remains unclear. Here, the efficacy and underlying mechanism of Limonitum decoction (LD) regarding diarrhoea were explored from the aspect of gut microbiota. Castor oil (CO) was used to induce diarrhoea in mice, which were then used to evaluate the effects of LD regarding the timing of the first defecation, diarrhoea stool rate, degree of diarrhoea, diarrhoea score, intestinal propulsive rate, and weight of intestinal contents. The concentrations of short-chain fatty acids (SCFAs), including acetic, propionic, isobutyric, butyric and valeric acids, were analysed by gas chromatography-mass spectrometry (GC-MS). The 16S rRNA high-throughput sequencing technology was applied to evaluate changes in the gut microbiota under exposure to LD. LD was found to effectively ameliorate the symptoms of diarrhoea, and the diversity and relative abundance of gut microbiota were restored to normal levels following LD treatment. Additionally, LD significantly restored the observed reductions in SCFAs. These results provide strong evidence that LD can sufficiently ameliorate diarrhoea in mice by regulating their gut microbiota. The findings presented here highlight that Limonitum may constitute a prospective remedy for diarrhoea.

Multifunctional Chiral Three-Dimensional Phosphite Frameworks Showing Dielectric Anomaly and High Proton Conductivity.

Chair 3D Co(II) phosphite frameworks have been prepared by the ionothermal method. It belongs to chiral space group P3221, and the whole framework can be topologically represented as a chiral 4-connected qtz net. It shows a multistep dielectric response arising from the reorientation of Me2-DABCO in the chiral cavities. It can also serve as a pron conductor with high conductivity, 1.71 × 10-3 S cm-1, at room temperature, which is attributed to the formation of denser hydrogen-bonding networks providing efficient proton-transfer pathways.

Analysis of risk factors and prognosis of post-stroke pulmonary infection in integrated ICU.

OBJECTIVE: The incidence of SAP (stroke-associated pneumonia) is high in integrated ICU (Intensive Care Unit), and it might result in sepsis, which exacerbates the clinical outcome and increases mortality. It is necessary to investigate the epidemiological features of post-stroke infection and sepsis, identify the risk factors and analyze the prognosis. PATIENTS AND METHODS: We retrospectively analyzed the data of 329 patients with cerebral infarction or cerebral hemorrhage, from seven tertiary university hospitals in Suzhou, Jiangsu Province, between January 1, 2016, and December 31, 2016. Basic demographic and clinical data including common health evaluation, stroke severity, microbiological parameters, surgical interventions and treatments were recorded for the analysis. SAP was diagnosed according to the criteria and recommendation from American Heart Association (AHA). RESULTS: 188 (66.4%) patients suffered pneumonia, 124 patients were diagnosed as SAP. Compared with SAP, patients with non-SAP pulmonary infection had prolonged mechanical ventilation time, prolonged central venous catheter indwelling time, and higher incidence of sepsis (17.7% vs. 48.4%). 53 patients (18.7%) developed sepsis during hospitalization, whose mortality rate during hospitalization and the occurrence of neurologic dysfunction at 3 months were significantly increased (p<0.05). 130 positive results of sputum cultures were found. The detected pathogens were mainly gram-negative bacteria. The pathogenic detection rate of non-SAP patients with pulmonary infection was higher (78.1%). The in-hospital mortality was 16.3% and the related risk factors were higher NIHSS score at admission, lower GCS score at admission, pulmonary infection (especially non-SAP pulmonary infection) and sepsis during hospitalization. CONCLUSIONS: The incidence of pulmonary infection after stroke in the integrated ICU is high, and it is easy to be complicated with sepsis, prolonging the mechanical ventilation time, central venous catheter indwelling time and hospitalization time, and the prognosis of long-term neurological function is relatively poor. The definition of stroke-associated pneumonia has implications for the classification of clinical infections, the prediction of possible pathogenic pathogens, and the guidance of anti-infective treatment.

[The epidemic, prophylaxis and treatment of cholera in Su-Wan Liberated Area in 1946].

Rugao and Haian belonging to First Branch of Su-Wan Liberated Area found fulminant cholera in 1946. The fulminant cholera spread throughout the Su-Wan Liberated Area in a short period of time. Thus, local mass and military led by CPC actively launched the Movement of Epidemic Prevention. They took some actions to clear up the circumstance, eliminate the pathogen, prevent the food contamination and cut off the route of transmission. Vaccination was carried out on a large scale. As a result of these measure, the fulminant cholera was efficiently controlled.

[Epidemiology, diagnosis, treatment and control measures of trichinellosis in China: an overview].

Trichinellosis is a worldwide zoonotic parasitic disease, which may infect humans and a wide range of animals, including carnivores, herbivores and even birds. Humans get infections through ingestion of raw or semi-cooked meat or meat products containing live Trichinella larvae. Currently, this zoonosis is predominantly prevalent in southwestern, northeastern and central parts of China, which poses a great threat to human health and socioeconomic development. In addition, the emergent public health hazards caused by trichinellosis outbreaks greatly threaten human health and social stability. This review describes the current status, diagnosis, treatment and control measures of trichinellosis in China, so as to provide insights into trichinellosis control in the country.

MiR-133b inhibits MPP+-induced apoptosis in Parkinson's disease model by inhibiting the ERK1/2 signaling pathway.

OBJECTIVE: The aim of this study was to explore the effect of micro ribonucleic acid (miR)-133b on 1-methyl-4-phenylpyridinium ion (MPP+)-induced apoptosis in the Parkinson's disease (PD) model. MATERIALS AND METHODS: PC12 cells were induced by different concentrations of MPP+ to establish the PD cell model. Subsequently, the survival rate of PC12 cells was detected using Cell Counting Kit-8 (CCK-8) assay. Quantitative Reverse Transcription-Polymerase Chain Reaction (qRT-PCR) was used to detect the expression of miR-133b in the PD model induced by different concentrations of MPP+. Next, PC12 cells were transfected with miR-133b mimic and miR-negative control (NC), and divided into MPP+ group, MPP+ + miR-NC group and MPP+ + miR-133b mimic group. Transfection efficiency was verified using qRT-PCR. The apoptosis of cells was detected using terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL) assay. Moreover, the expressions of extracellular signal-regulated kinase 1/2 (ERK1/2) and phosphorylated (p)-ERK1/2 were determined using Western blotting. RESULTS: After MPP+ treatment, the survival rate of PC12 cells significantly declined (p<0.05). MPP+ exhibited toxicity against PC12 cells in a concentration-dependent manner. Meanwhile, cell survival rate decreased remarkably with the increase of MPP+ concentration (p<0.05). With increased concentration of MPP+, the expression of miR-133b in the PD cell model declined significantly (p<0.05). The apoptosis of PC12 cells was remarkably inhibited by overexpression of miR-133b in the PD cell model (p<0.05). In addition, the protein expression of p-ERK1/2 in PC12 cells was notably reduced after overexpression of miR-133b in the PD cell model (p<0.05). CONCLUSIONS: MiR-133b is lowly expressed in the PD cell model. Furthermore, overexpression of miR-133b inhibits cell apoptosis in the PD cell model by regulating the ERK1/2 signaling pathway.
