Abstract
Objective: To explore the cutting scheme and clinical application effects of ultrathin thoracodorsal artery perforator flap assisted by color Doppler ultrasound. Methods: This study was a retrospective historical control study. From February 2017 to October 2019, 20 patients who were admitted to the Third Department of Orthopedics of Xingtai General Hospital of North China Medical and Health Group (hereinafter referred to as our department), met the inclusion criteria, and underwent repair of skin and soft tissue defects of extremities with ultrathin thoracodorsal artery perforator flap designed and harvested based on the surgeon's clinical experience were selected as control group, including 16 males and 4 females, aged (37±5) years. From November 2019 to December 2022, 21 patients who were admitted to our department, met the inclusion criteria, and underwent repair of skin and soft tissue defects of extremities with ultrathin thoracodorsal artery perforator flap designed and harvested under the assistance of color Doppler ultrasound were selected as ultrasound-assisted group, including 15 males and 6 females, aged (38±6) years. After debridement, the area of skin and soft tissue defects of extremities ranged 5.0 cm×4.0 cm to 19.0 cm×8.0 cm, and the area of thoracodorsal artery perforator flaps ranged 6.0 cm×5.0 cm to 20.0 cm×9.0 cm. The wounds in flap donor sites were closed directly. For patients in ultrasound-assisted group, the time and cost required for color Doppler ultrasound examination were recorded, and the number, type, and location of thoracodorsal artery perforator vessels detected by preoperative color Doppler ultrasound were compared with those of intraoperative actual detection. The time required for complete flap harvest of patients in 2 groups was recorded. On postoperative day (POD) 1, 3, 5, 7, and 14, the blood perfusion of flaps in the 2 groups of patients was assessed using a flap perfusion assessment scale. On POD 14, flap survival of patients in 2 groups was observed, and the percentage of flap survival area was calculated. In postoperative 6 months, satisfaction of patients with the treatment outcome in the 2 groups was assessed using 5-grade Likert scale, and the satisfaction rate was calculated. Results: For patients in ultrasound-assisted group, the time required for preoperative color Doppler ultrasound examination was (10.5±2.3) min, and the cost was 120 yuan; 21 thoracodorsal artery perforator vessels were detected and marked using preoperative color Doppler ultrasound, including 8 (38.10%) type 1 perforator vessels, 10 (47.62%) type 2 perforator vessels, and 3 (14.29%) type 3 perforator vessels; the number, type, and location of thoracodorsal artery perforator vessels detected preoperatively were consistent with those detected intraoperatively. The time required for complete flap harvest of patients in ultrasound-assisted group was (41±10) min, which was significantly shorter than (63±12) min in control group (t=6.32, P<0.05). On POD 1, 3, 5, 7, and 14, the blood perfusion scores of flaps of patients in ultrasound-assisted group were significantly better than those in control group (with t values of 6.67, 7.48, 8.03, 8.75, and 7.99, respectively P<0.05). On POD 14, only one patient in ultrasound-assisted group had partial flap necrosis and 6 patients in control group had complete or partial necrosis of the flap; the percentage of flap survival area of patients in ultrasound-assisted group was (99±8)%, which was significantly higher than (87±8)% in control group (t=4.57, P<0.05). In postoperative 6 months, there was no significant difference in the satisfaction rate of patients with the treatment outcome between the two groups (P>0.05). Conclusions: Preoperative color Doppler ultrasound is highly accurate in detecting the number, type, and location of perforator vessels. The cutting scheme of ultrathin thoracodorsal artery perforator flaps can be designed according to the different types of perforator vessels, with shorted flap cutting time and improved flap survival rate.

Abstract
The incidence of allergic rhinitis (AR) is increasing year by year, especially in children. AR not only affects the growth, development, life and learning of children but also causes huge economic and social burdens. This study explores the impact of individual factors such as genetic polymorphisms, epigenetics, inflammatory response mechanisms, and microecological influence mechanisms on children's AR. It also reviews the impact of external factors such as allergenic factors, ambient air pollutants, infection and immunity factors, and climate and climate change on the disease, with the aim of improving understanding of AR in children and providing a basis for its prevention and treatment.

Abstract
Objective: To explore the value of catheter-based adrenal ablation in treating Cushing's syndrome (CS)-associated hypertension. Methods: A clinical study was conducted in patients with CS, who received catheter-based adrenal ablation between March 2018 and July 2023 in Daping Hospital. Parameters monitored were blood pressure (outpatient and 24-hour ambulatory), body weight, clinical characteristics, serum cortisol and adrenocorticotropic hormone (ACTH) at 8 am, 24-hour urinary free cortisol (24 h UFC), fasting blood glucose and postoperative complications. Procedure effectiveness was defined as blood pressure returning to normal levels (systolic blood pressure<140 mmHg (1 mmHg=0.133 kPa) and diastolic blood pressure<90 mmHg), cortisol and 24 h UFC returning to normal and improvement of clinical characteristics. The parameters were monitored during follow up in the outpatient department at 1, 3, 6, and 12 months after catheter-based adrenal ablation. Results: A total of 12 patients (aged (40.0±13.2) years) were reviewed. There were 5 males, with 5 cases of adenoma and 7 with hyperplasia from imaging studies. Catheter-based adrenal ablation was successful in all without interruption or surgical conversion. No postoperative complication including bleeding, puncture site infection, adrenal artery rupture or adrenal bleeding was observed. The mean follow up was 28 months. Compared to baseline values, body weight declined to (59.48±11.65) kg from (64.81±10.75) kg (P=0.008), fasting blood glucose declined to (4.54±0.83) mmol from (5.53±0.99) mmol (P=0.044), outpatient systolic blood pressure declined to (128±21) mmHg from (140±19) mmHg (P=0.005), diastolic blood pressure declined to (78±10) mmHg from (86±11) mmHg (P=0.041), and the mean ambulatory daytime diastolic blood pressure declined to (79±12) mmHg from (89±8) mmHg (P=0.034). Catheter-based adrenal ablation in 8 patients was defined as effective with their 24 h UFC significantly reduced after the procedure (1 338.41±448.06) mmol/L from (633.66±315.94) mmol/L, P=0.011). The change of 24 h UFC between the effective treatment group and ineffective group was statistically significant (P=0.020). The postoperative systolic blood pressure in the treated adenoma group was significantly lower than those of hyperplasia group (112±13) mmHg vs. (139±20) mmHg, P=0.026). Conclusions: For patients with CS-associated hypertension who are unwilling or unable to undergo surgical treatment, catheter-based adrenal ablation could improve the blood pressure and cortisol level. Catheter-based adrenal ablation could be a safe, effective, and minimally invasive therapy. However, our results still need to be validated in further large-scale studies.

Abstract
Objective: To analyze the incidence and the related risk factors of retropharyngeal lymph node metastasis in patients with hypopharyngeal squamous cell carcinoma, evaluate the accuracy of preoperative enhanced CT in judging retropharyngeal lymph node metastasis, and investigate the impact of retropharyngeal lymph node metastasis on the prognosis. Methods: Retrospective analyses were made on 398 patients with hypopharyngeal squamous cell carcinoma who underwent surgery as the primary therapy and accepted retropharyngeal lymph node exploration and clearance during surgery in Shandong Provincial ENT Hospital from January 2014 to December 2019. Multivariate logistic regression analysis was used to clarify the related risk factors of retropharyngeal lymph node metastasis. Multivariate Cox regression analysis was used to investigate the impact of retropharyngeal lymph node metastasis on prognosis. The retropharyngeal lymph nodes of 218 cases with available preoperative enhanced CT images were evaluated by two experienced radiologists and compared with postoperative pathological results. Results: Retropharyngeal lymph node metastasis were confirmed in 54 of 398 (13.6%) cases according to postoperative pathology. The sensitivity and specificity of preoperative enhanced CT in the diagnosis of retropharyngeal lymph node metastasis were 34.6% and 91.1%, respectively, and the overall accuracy was 84.4%. Multivariate logistic regression analysis showed that the site of the primary lesion and pathological N stage were independent risk factors for retropharyngeal lymph node metastasis in hypopharyngeal squamous cell carcinoma. Patients with primary lesion located in the posterior wall of hypopharynx (OR=4.83, 95% CI: 1.27-18.40), N2 stage (OR=6.30, 95% CI: 2.25-17.67), and N3 stage (OR=26.89, 95% CI: 5.76-125.58) were prone to retropharyngeal lymph node metastasis. The 5-year overall survival rate of the 398 patients was 50.4%, and the 5-year disease-free survival rate was 48.3%. Multivariate Cox regression analysis showed that T stage, N stage, retropharyngeal lymph node metastasis, and radiotherapy were independent influencing factors for overall survival (T stage: HR=1.28, 95% CI: 1.06-1.54; N stage: HR=1.26, 95% CI: 1.14-1.40; retropharyngeal lymph node metastasis: HR=2.13, 95% CI: 1.47-3.08; radiotherapy: HR=0.54, 95% CI: 0.38-0.76) and disease-free survival of patients with hypopharyngeal squamous cell carcinoma (T stage: HR=1.26, 95% CI: 1.06-1.51; N stage: HR=1.25, 95% CI: 1.13-1.37; retropharyngeal lymph node metastasis: HR=2.24, 95% CI: 1.56-3.21; radiotherapy: HR=0.55, 95% CI: 0.40-0.77). Conclusions: Metastasis of retropharyngeal lymph nodes in hypopharyngeal squamous cell carcinoma is not rare. Enhanced CT is of low accuracy and limited value in diagnosing retropharyngeal lymph node metastasis. Primary lesions located in the posterior wall of the hypopharyngx, N2 stage, and N3 stage are independent high-risk factors for retropharyngeal lymph node metastasis. The prognosis of hypopharyngeal cancer patients with retropharyngeal lymph node metastasis is worse, and active surgical exploration and clearance can effectively reduce the mortality caused by retropharyngeal lymph node metastasis.

Abstract
Objective: To analyze and compare therapy responses, outcomes, and incidence of severe hematologic adverse events of flumatinib and imatinib in patients newly diagnosed with chronic phase chronic myeloid leukemia (CML) . Methods: Data of patients with chronic phase CML diagnosed between January 2006 and November 2022 from 76 centers, aged ≥18 years, and received initial flumatinib or imatinib therapy within 6 months after diagnosis in China were retrospectively interrogated. Propensity score matching (PSM) analysis was performed to reduce the bias of the initial TKI selection, and the therapy responses and outcomes of patients receiving initial flumatinib or imatinib therapy were compared. Results: A total of 4 833 adult patients with CML receiving initial imatinib (n=4 380) or flumatinib (n=453) therapy were included in the study. In the imatinib cohort, the median follow-up time was 54 [interquartile range (IQR), 31-85] months, and the 7-year cumulative incidences of CCyR, MMR, MR(4), and MR(4.5) were 95.2%, 88.4%, 78.3%, and 63.0%, respectively. The 7-year FFS, PFS, and OS rates were 71.8%, 93.0%, and 96.9%, respectively. With the median follow-up of 18 (IQR, 13-25) months in the flumatinib cohort, the 2-year cumulative incidences of CCyR, MMR, MR(4), and MR(4.5) were 95.4%, 86.5%, 58.4%, and 46.6%, respectively. The 2-year FFS, PFS, and OS rates were 80.1%, 95.0%, and 99.5%, respectively. The PSM analysis indicated that patients receiving initial flumatinib therapy had significantly higher cumulative incidences of CCyR, MMR, MR(4), and MR(4.5) and higher probabilities of FFS than those receiving the initial imatinib therapy (all P<0.001), whereas the PFS (P=0.230) and OS (P=0.268) were comparable between the two cohorts. The incidence of severe hematologic adverse events (grade≥Ⅲ) was comparable in the two cohorts. Conclusion: Patients receiving initial flumatinib therapy had higher cumulative incidences of therapy responses and higher probability of FFS than those receiving initial imatinib therapy, whereas the incidence of severe hematologic adverse events was comparable between the two cohorts.

Abstract
Objective: To investigate the clinicopathological features, immunophenotype, and genetic alterations of rectal adenocarcinoma with enteroblastic differentiation. Methods: Four cases of rectal adenocarcinoma with enteroblastic differentiation were collected at the Affiliated Hospital of Qingdao University, Qingdao, China (three cases) and Yantai Yeda Hospital of Shandong Province, China (one case) from January to December 2022. Their clinical features were summarized. Hematoxylin and eosin stain and immunohistochemical stain were performed, while next-generation sequencing was performed to reveal the genetic alterations of these cases. Results: All four patients were male with a median age of 65.5 years. The clinical manifestations were changes of stool characteristics, bloody stools and weight loss. All cases showed mixed morphology composed of conventional adenocarcinoma and adenocarcinoma with enteroblastic differentiation. Most of the tumors consisted of glands with tubular and cribriform features. In one case, almost all tumor cells were arranged in papillary structures. The tumor cells with enteroblastic differentiation were columnar, with relatively distinct cell boundaries and characteristic abundant clear cytoplasm, forming fetal gut-like glands. Immunohistochemically, the tumor cells were positive for SALL4 (4/4), Glypican-3 (3/4) and AFP (1/4, focally positive), while p53 stain showed mutated type in 2 cases. The next-generation sequencing revealed that 2 cases had TP53 gene mutation and 1 case had KRAS gene mutation. Conclusions: Rectal adenocarcinoma with enteroblastic differentiation is rare. It shows embryonal differentiation in morphology and immunohistochemistry, and should be distinguished from conventional colorectal adenocarcinoma.

Abstract
Objective: To study the incidence of bloodstream infections, pathogen distribution, and antibiotic resistance profile in patients with hematological malignancies. Methods: From January 2018 to December 2021, we retrospectively analyzed the clinical characteristics, pathogen distribution, and antibiotic resistance profiles of patients with malignant hematological diseases and bloodstream infections in the Department of Hematology, Nanfang Hospital, Southern Medical University. Results: A total of 582 incidences of bloodstream infections occurred in 22,717 inpatients. From 2018 to 2021, the incidence rates of bloodstream infections were 2.79%, 2.99%, 2.79%, and 2.02%, respectively. Five hundred ninety-nine types of bacteria were recovered from blood cultures, with 487 (81.3%) gram-negative bacteria, such as Klebsiella pneumonia, Escherichia coli, and Pseudomonas aeruginosa. Eighty-one (13.5%) were gram-positive bacteria, primarily Staphylococcus aureus, Staphylococcus epidermidis, and Enterococcus faecium, whereas the remaining 31 (5.2%) were fungi. Enterobacteriaceae resistance to carbapenems, piperacillin/tazobactam, cefoperazone sodium/sulbactam, and tigecycline were 11.0%, 15.3%, 15.4%, and 3.3%, with a descending trend year on year. Non-fermenters tolerated piperacillin/tazobactam, cefoperazone sodium/sulbactam, and quinolones at 29.6%, 13.3%, and 21.7%, respectively. However, only two gram-positive bacteria isolates were shown to be resistant to glycopeptide antibiotics. Conclusions: Bloodstream pathogens in hematological malignancies were broadly dispersed, most of which were gram-negative bacteria. Antibiotic resistance rates vary greatly between species. Our research serves as a valuable resource for the selection of empirical antibiotics.

Abstract
Objective: To retrospectively analyse the efficacy of surgerical comprehensive treatment for hypopharyngeal cancer. Methods: Four hundred and fifty-six cases of hypopharyngeal squamous cell carcinoma treated from Jan 2014 to Dec 2019 were analyzed retrospectively, including 432 males and 24 females, aged 37-82 years old. There were 328 cases of pyriform sinus carcinoma, 88 cases of posterior pharyngeal wall carcinoma, and 40 cases of postcricoid carcinoma. According to American Joint Committe on Cancer(AJCC) 2018 criteria, 420 cases were of stage Ⅲ or Ⅳ; 325 cases were of T3 or T4 stage. Treatment methods included surgery alone in 84 cases, preoperative planned radiotherapy plus surgery in 49 cases, surgery plus adjuvant radiotherapy or concurrent chemoradiotherapy in 314 cases, and inductive chemotherapy plus surgery and adjuvant radiotherapy in 9 cases. The primary tumor resection methods included transoral laser surgery in 5 cases, partial laryngopharyngectomy in 74 cases, of them 48 cases (64.9%) presented with supracricoid hemilaryngopharyngectomy, total laryngectomy with patial pharyngectomy in 90 cases, total laryngopharyngectomy or with cervical esophagectomy in 226 cases, and total laryngopharyngectomy with total esophagectomy in 61 cases. Among 456 cases, 226 cases received reconstruction surgery with free jejunum transplantation, 61 cases with gastric pull-up, and 32 cases with pectoralis myocutaneous flaps. All patients underwent retropharyngeal lymph node dissection, and high-definition gastroscopy was performed during admission and follow-up. SPSS 24.0 software was used to analyze the data. Results: The 3-year and 5-year overall survival rates were respectively 59.8%, and 49.5%. The 3-year and 5-year disease specific survival rates were respectively 69.0% and 58.8%. Total metastasis rate of retropharyngeal lymph nodes was 12.7%. A total of 132 patients (28.9%) suffered from simultaneous and metachronous multiple primary carcinoma of the hypopharynx. Multivariate Logistic regression analysis showed that T3-4 disease, cervical lymph node metastasis, retropharyngeal lymph node metastasis and postoperative adjuvant radiotherapy were independent factors affecting the prognosis of patients (all P<0.05). As of April 30, 2022, a total of 221 patients died during follow-up, of 109 (49.3%) with distant metastases, which were the main cause of death. Conclusions: The efficacy of comprehensive treatment for hypopharyngeal cancer can be improved by accurate preoperative evaluation, improved surgical resection, active retropharyngeal lymph node dissection and full process intervention of the second primary cancer.

Abstract
Objective: To investigate the clinical application value of the modified Lee grading system (abbreviated as the modified system) in evaluating the degree of intervertebral foraminal stenosis(IFS) in patients with foraminal lumbar disc herniations(FLDH). Methods: MRI data of 83 patients with FLDH-IFS (34 patients in the operation group and 49 patients in the conservative group) in Yantai Affiliated Hospital of Binzhou Medical University and Yantai Yantaishan Hospital from March 2018 to February 2021 were retrospectively collected. There were 43 males and 40 females, ranged from 34 to 82 years old, with an average of (61±10) years. MRI images of selected patients were independently evaluated and recorded by two radiologists in a blind method, using both the Lee grading system (abbreviated as Lee system) and the modified system, respectively and each method was evaluated twice. The difference between the evaluation level of the two systems, and the agreement of observer assessments of the two systems were compared, and the correlation between the evaluation level of the two grading systems and the clinical treatment modalities was analyzed. Results: The percentage of nongrade 3 (grade 0-2) patients with effective conservative treatment according to the two grading systems was 94.6 % (139/147) and 64.2 % (170/265), respectively. The percentage of grade 3 patients requiring surgical treatment according to the two grading systems was 69.2 % (128/185) and 61.2 % (41/67), respectively. There was a statistically significant difference between the evaluation levels of the modified system and the Lee system (Z=-5.16, P=0.001). In the Lee system, the intra-observer observation consistency Kappa values of the two radiologists were 0.735 and 0.542, respectively, which were highly and moderately consistent; and the inter-observer observation consistency Kappa values were 0.426-0.521, which were moderate consistency. In the modified system, the intra-observer consistency Kappa values of the two radiologists were 0.900 and 0.921, respectively, and the consistency was almost completely consistent; and the inter-observer consistency Kappa values were 0.783-0.861, which were highly consistent or almost completely consistent. Lee system and clinical treatment modalities was correlative (rs=0.39,P<0.001), and modified system and clinical treatment modalities was correlative (rs=0.61,P<0.001). Conclusion: According to FLDH-IFS, the modified system can comprehensively and accurately grade, with high reliability and reproducibility. The evaluation level has a more significant correlation with clinical treatment modalities.

Abstract
Herein, previously unreported Fischer's base reactants serving as useful 2C building blocks in (3+2) cycloaddition reactions to build a library of bispiro[Fischer's base-oxindole] hybrids are described. These structurally intriguing products containing three adjacent quaternary stereocentres were smoothly afforded in up to 82% yield and >20 : 1 dr under catalyst-free conditions. Notably, the present protocol firstly employs 3-isothiocyanato oxindole serving as an acceptor and then as a donor in the formal (3+2) cycloadditions, allowing practical, straightforward access to structurally diverse cycloadducts. This work expands the applicability scope of 3-isothiocyanato oxindoles, which have been limited to behaving as donor/acceptor-based synthons in cycloadditions in previous work.

Abstract
Objectives: To investigate the clinical and genetic features of young Chinese patients with myeloproliferative neoplasms (MPN). Methods: In this cross-sectional study, anonymous questionnaires were distributed to patients with MPN patients nationwide. The respondents were divided into 3 groups based on their age at diagnosis: young (≤40 years) , middle-aged (41-60 years) , and elderly (>60 years) . We compared the clinical and genetic characteristics of three groups of MPN patients. Results: 1727 assessable questionnaires were collected. There were 453 (26.2%) young respondents with MPNs, including 274 with essential thrombocythemia (ET) , 80 with polycythemia vera (PV) , and 99 with myelofibrosis. Among the young group, 178 (39.3%) were male, and the median age was 31 (18-40) years. In comparison to middle-aged and elderly respondents, young respondents with MPN were more likely to present with a higher proportion of unmarried status (all P<0.001) , a higher education level (all P<0.001) , less comorbidity (ies) , fewer medications (all P<0.001) , and low-risk stratification (all P<0.001) . Younger respondents experienced headache (ET, P<0.001; PV, P=0.007; MF, P=0.001) at diagnosis, had splenomegaly at diagnosis (PV, P<0.001) , and survey (ET, P=0.052; PV, P=0.063) . Younger respondents had fewer thrombotic events at diagnosis (ET, P<0.001; PV, P=0.011) and during the survey (ET, P<0.001; PV, P=0.003) . JAK2 mutations were found in fewer young people (ET, P<0.001; PV, P<0.001; MF, P=0.013) ; however, CALR mutations were found in more young people (ET, P<0.001; MF, P=0.015) . Furthermore, mutations in non-driver genes (ET, P=0.042; PV, P=0.043; MF, P=0.004) and high-molecular risk mutations (ET, P=0.024; PV, P=0.023; MF, P=0.001) were found in fewer young respondents. Conclusion: Compared with middle-aged and elderly patients, young patients with MPN had unique clinical and genetic characteristics.

Abstract
Objective: Exploring the neuropsychological developmental characteristics and influencing factors of children with speech disorder. Methods: A case-control study was conducted. A total of 395 children diagnosed with speech disorders were selected as speech sound disorder (SSD) group from January 2019 to September 2021 in the speech-speech outpatient department of the Children's Hospital Affiliated to Capital Institute of Pediatrics, and 1 179 healthy children who underwent physical examination in the health department during the same period were selected as the control group. All the children were examined by the "Children's Neuropsychological Behavior Scale 2016 Edition" (Children's Mind Scale 2016 edition). Independent sample t test was used to compare the developmental levels of the two groups of children, including total developmental quotient, gross motor, fine motor, adaptive ability, language and social behavior ability. The influential factors of children's speech disorders were analyzed by univariate Chi-square analysis and multivariate logistic regression. Results: There were 395 SSD children, including 296 males and 99 females, 4≤ age ≤6, (4.71±0.76) years. There were 1 179 children in the control group, including 864 males and 315 females, 4≤ age ≤6, (4.64±0.78) years. The mean value of total developmental factors in SSD group was lower than that in control group [(86.45±11.57)/(91.24±8.0), t=-7.78, P<0.01], and the mean values of total developmental markers in both boys and girls in SSD group were lower than those in control group [(86.00±11.40)/(90.78±7.86), t=-6.70, P<0.01; (87.82±12.03)/(92.87±8.49), t=-3.88, P<0.01]. The mean values of gross motor, fine motor, adaptive ability, language ability and social behavior in SSD group were lower than those in control group [(89.76±12.47)/(92.01±10.69), t=-3.21, P<0.01; (80.62±13.64)/(84.49±11.55), t=-5.06, P<0.01; (87.92±15.25)/(92.98±12.06), t=-6.00, P<0.01; (86.48±16.30)/(94.55±12.08), t=-9.04, P<0.01; (87.02±15.18)/(92.63±12.57), t=-6.62, P<0.01]; The mean value of fine motor in boys was lower than that in girls in SSD group [(79.80±13.42)/(83.08±14.05), t=-2.08, P<0.05]. Independent mealtimes. 2 years old (OR=1.527, 95%CI: 1.180-1.977, P=0.001), delay in adding supplemental food (OR=1.510, 95%CI: 1.123-2.029, P=0.006), dialect in the home language environment (OR=1.351, 95%CI: 1.060-1.723, P=0.015) were risk factors for children with speech disorders. Conclusion: Children with speech disorders are more common in boys. The overall development level of SSD children is lower than that of normal children, and the fine motor of SSD boys is lower than that of girls. The incidence of children's speech disorders is related to the addition time of supplementary food, independent meal time and family language environment.

Abstract
We report an efficient alkyl transfer strategy for the direct β-alkylation of chalcones using commercially available alkyl bromides as alkyl reagents. In this transformation, the ortho-phosphanyl substituent in the chalcones is crucial for controlling their reactivity and selectivity. It also serves as a reliable alkyl transfer shuttle to transform electrophilic alkyl bromides into nucleophilic alkyl species in the form of quaternary phosphonium salts and transfer the alkyl group effectively to the β-position of the chalcones. This alkyl transfer strategy can be further extended to the alkenylation of ortho-phosphanyl benzaldehydes to assemble functionalized polyenes.

Abstract
Hyperoside (HP), as a natural product, can promote proliferation and differentiation of osteoblasts and presents a protective effect on ovariectomized (OVX) mice. However, the inhibitory effect of HP on osteoclasts (OCs) and the potential mechanism remain to be elucidated. In this study, it was found that HP could effectively inhibit the differentiation and bone resorption of OCs, and its intrinsic molecular mechanism was related to the inhibition of TRAF6/p38 MAPK signaling pathway. Therefore, HP could be a promising natural compound for lytic bone diseases.

Abstract
The first enantioselective formal (3 + 2) cyclocondensation involving α,β-unsaturated pyrazoleamides as 3-carbon partners was accomplished in a stepwise fashion. The stepwise esterification/Michael addition sequence is promoted by Zn(OTf)2 and quinine-squaramide derivative, respectively. The protocol enables access to spiro-fused pentacyclic spirooxindoles from coumarin-3-formylpyrazoles and 3-hydroxyoxindoles in good to satisfactory overall yields (up to 91%) with excellent dr (all cases >20:1 dr) and high ee values (up to 99%). Mechanistic investigations contributed to shedding light on the enantioselective event of the process.

Abstract
Objective: To evaluate the quality of life and influencing factors of patients with herpes zoster (HZ) seen in hospitals. Methods: Based on Zoster Brief Pain Inventory (ZBPI) and Five-level EuroQol Five-dimensional Questionnaire (EQ-5D-5L), a cross-sectional survey was conducted to evaluate the pain severity and quality of life of 332 HZ cases seen in 22 hospitals of Lu'an City (Anhui Province), Zibo City (Shandong Province) and Tongchuan City (Shaanxi Province) from October to December 2021. The censored least absolute deviations (CLAD) model was used to analyze the related factors affecting the changes of patients' health utility values. Results: The 45.5% of 332 HZ cases were male. The median (Q1,Q3) age was 59 (50, 68) years. 59.64% of them assessed by ZBPI had moderate to severe pain in the past 24 hours (worst pain score≥5), and that of PHN cases was 84.8%(39/46). 77.7% (258/332), 77.4% (257/332) and 74.1% (246/332) of all patients reported that pain interfered with sleep, mood and general activities, respectively. Aging [β40-49y (95%CI)=-0.11 (-0.15, -0.08); β50-59y (95%CI)=-0.03 (-0.05, 0.00); β60-69y (95%CI)=-0.09 (-0.12, -0.06); β70-90y(95%CI)=-0.16 (-0.19, -0.12)], working status (unemployed) [βfarmer (95%CI)=0.15 (0.13, 0.18); βretirees(95%CI)=0.21 (0.18, 0.24); βemployee (95%CI)=0.13 (0.10, 0.16) ], complications[βPHN (95%CI)=-0.08 (-0.13, -0.04); βother complications (95%CI)=-0.12 (-0.15, -0.08)], within 30 days after onset [β(95%CI)=-0.01 (-0.03, 0.01)] and treatment [βother complications (95%CI)=-0.09 (-0.11, -0.06)] were related factors for the decline of health utility value (all P values <0.05). Conclusions: More than half of the patients with HZ had moderate to severe pain in the past 24 hours, which had a serious negative impact on the physical and mental health of the patients. Elderly patients, acute patients and patients with complications had lower health utility values and worse health status. We suggest that eligible people be vaccinated with HZ vaccine as soon as possible.

Abstract
Objective: To investigate the clinicopathological characteristics, immunophenotype, and molecular signatures of oncocytic papillary renal cell carcinoma (OPRCC), and to compare these findings with those in type 1 papillary renal cell carcinoma (PRCC 1). Methods: The clinicopathologic data of 19 patients with OPRCC from the Affiliated Hospital of Qingdao University (16 patients) and the 971 Hospital of People's Liberation Army Navy (3 patients) from October 2003 to February 2021 were collected. Histologic, immunohistochemical (IHC) and molecular analyses, together with a control group of 15 cases of PRCC I diagnosed in the same period, were assessed. Results: The cohort included 15 males and 4 females, with a median age of 61 years (range, 47-78 years). In 13 patients the tumors were found at physical examination; four presented with painless gross hematuria and two with low back pain. As for the pathologic stage, 14 patients were pT1, one patient was pT2a, three patients were pT3a and one patient was pT4. The tumor size ranged from 1.7-14.0 cm, with clear boundary and soft texture. The cut surface was grayish-yellow and grayish-red. Microscopically, the tumor cells were mainly arranged in papillary (10%-100%) and acinar (tubular) patterns, with strongly eosinophilic cytoplasm, round or irregular nuclei, and prominent nucleoli (WHO/ISUP grade Ⅲ). Two cases showed sarcomatoid differentiation. Stromal foamy macrophages were visible in all cases. IHC staining showed diffuse strong positivity for AMACR in all cases. RCC (18/19), CD10 (17/19), vimentin (16/19) and PAX8 (17/19) were positive in most tumors. CK7 was expressed in about 50% of cases. Fluorescence in situ hybridization identified trisomy 7 in eight patients, trisomy 17 in seven patients, and the two aberrations occurred simultaneously in seven cases. Eight of 13 men had Y chromosome deletion. All patients were followed up for 8-120 months. Three patients died of metastases at 8, 62 and 82 months postoperatively, respectively, and one patient relapsed 36 months after surgery. Compared with PRCC1, OPRCC tended to have higher nuclear grade, and stromal foam cell aggregation was more commonly found (P<0.05). The expression of CD10 and EMA were different (P<0.01). There was no significant difference in the survival rate between the two groups (P=0.239). Conclusions: OPRCC has unique morphologic features, and its immunophenotype overlaps but differs from PRCC1. The molecular results support that it belongs to a morphologic variation of PRCC. This tumor has similar biologic behavior to PRCC1, and has a poor prognosis when sarcomatoid differentiation occurs.

Abstract
Objective: To analyze the clinical epidemiological characteristics including composition of pathogens , clinical characteristics, and disease prognosis acute bacterial meningitis (ABM) in Chinese children. Methods: A retrospective analysis was performed on the clinical and laboratory data of 1 610 children <15 years of age with ABM in 33 tertiary hospitals in China from January 2019 to December 2020. Patients were divided into different groups according to age,<28 days group, 28 days to <3 months group, 3 months to <1 year group, 1-<5 years of age group, 5-<15 years of age group; etiology confirmed group and clinically diagnosed group according to etiology diagnosis. Non-numeric variables were analyzed with the Chi-square test or Fisher's exact test, while non-normal distrituction numeric variables were compared with nonparametric test. Results: Among 1 610 children with ABM, 955 were male and 650 were female (5 cases were not provided with gender information), and the age of onset was 1.5 (0.5, 5.5) months. There were 588 cases age from <28 days, 462 cases age from 28 days to <3 months, 302 cases age from 3 months to <1 year of age group, 156 cases in the 1-<5 years of age and 101 cases in the 5-<15 years of age. The detection rates were 38.8% (95/245) and 31.5% (70/222) of Escherichia coli and 27.8% (68/245) and 35.1% (78/222) of Streptococcus agalactiae in infants younger than 28 days of age and 28 days to 3 months of age; the detection rates of Streptococcus pneumonia, Escherichia coli, and Streptococcus agalactiae were 34.3% (61/178), 14.0% (25/178) and 13.5% (24/178) in the 3 months of age to <1 year of age group; the dominant pathogens were Streptococcus pneumoniae and the detection rate were 67.9% (74/109) and 44.4% (16/36) in the 1-<5 years of age and 5-<15 years of age . There were 9.7% (19/195) strains of Escherichia coli producing ultra-broad-spectrum β-lactamases. The positive rates of cerebrospinal fluid (CSF) culture and blood culture were 32.2% (515/1 598) and 25.0% (400/1 598), while 38.2% (126/330)and 25.3% (21/83) in CSF metagenomics next generation sequencing and Streptococcus pneumoniae antigen detection. There were 4.3% (32/790) cases of which CSF white blood cell counts were normal in etiology confirmed group. Among 1 610 children with ABM, main intracranial imaging complications were subdural effusion and (or) empyema in 349 cases (21.7%), hydrocephalus in 233 cases (14.5%), brain abscess in 178 cases (11.1%), and other cerebrovascular diseases, including encephalomalacia, cerebral infarction, and encephalatrophy, in 174 cases (10.8%). Among the 166 cases (10.3%) with unfavorable outcome, 32 cases (2.0%) died among whom 24 cases died before 1 year of age, and 37 cases (2.3%) had recurrence among whom 25 cases had recurrence within 3 weeks. The incidences of subdural effusion and (or) empyema, brain abscess and ependymitis in the etiology confirmed group were significantly higher than those in the clinically diagnosed group (26.2% (207/790) vs. 17.3% (142/820), 13.0% (103/790) vs. 9.1% (75/820), 4.6% (36/790) vs. 2.7% (22/820), χ2=18.71, 6.20, 4.07, all P<0.05), but there was no significant difference in the unfavorable outcomes, mortility, and recurrence between these 2 groups (all P>0.05). Conclusions: The onset age of ABM in children is usually within 1 year of age, especially <3 months. The common pathogens in infants <3 months of age are Escherichia coli and Streptococcus agalactiae, and the dominant pathogen in infant ≥3 months is Streptococcus pneumoniae. Subdural effusion and (or) empyema and hydrocephalus are common complications. ABM should not be excluded even if CSF white blood cell counts is within normal range. Standardized bacteriological examination should be paid more attention to increase the pathogenic detection rate. Non-culture CSF detection methods may facilitate the pathogenic diagnosis.

Abstract
Objective: To explore the safety and feasibility of stereotactic radiation therapy (SBRT) strategy for irradiating porcine ventricular septum, see if can provide a preliminary experimental evidence for clinical SBRT in patients with hypertrophic obstructive cardiomyopathy (HOCM). Methods: Five male pigs (39-49 kg, 6 months old) were used in this study. Pigs were irradiated at doses of 25 Gy (n=2) or 40 Gy (n=3). Delineation of the target volume was achieved under the guidance of 3-dimensional CT image reconstruction, and SBRT was then performed on defined target volume of porcine ventricular septum. Blood biomarkers, electrocardiogram and echocardiography parameters were monitored before and after SBRT. Pathological examination (HE staining, Masson staining) was performed on the target and non-target myocardium at 6 months post SBRT. Results: SBRT was successful and all animals survived to the designed study endpoint (6 months) after SBRT. Serum cardiac troponin T (cTnT) level was significantly higher than the baseline level at 1 day post SBRT, and reduced at 1 week after SBRT, but was still higher than the baseline level(P<0.05). Serum N-terminal pro-B type natriuretic peptide (NT-proBNP) was also significantly increased at 1 day post SBRT (P<0.05) and returned to baseline level at 1 week post SBRT. The serum NT-proBNP level was (249±78), (594±37) and (234±46) pg/ml, respectively, and the cTnT was (14±7), (240±40) and (46±34) pg/ml, respectively at baseline, 1 day and 1 week after SBRT in the 40 Gy dose group. The serum NT-proBNP level was (184±20), (451±49) and (209±36) pg/ml, respectively, the cTnT values were (9±1), (176±29) and (89±27) pg/ml, respectively at baseline, 1 day and 1 week after SBRT in the 25 Gy dose group. Both NT-proBNP and cTnT values tended to be higher post SBRT in the 40 Gy dose group as compared with the 25 Gy dose group, but the difference was not statistically significant (P>0.05). The left ventricular ejection fraction and the left ventricular end-diastolic diameter remained unchanged before and after SBRT (P>0.05). The interventricular septum thickness showed a decreasing trend at 6 months after SBRT, but the difference was not statistically significant ((9.54±0.24) mm vs. (9.82±8.00) mm, P>0.05). The flow velocity of the left ventricular outflow tract, and the valve function and morphology were not affected by SBRT. At 6 months after SBRT, HE staining revealed necrosis in the irradiated target area of the myocardium in the 40 Gy dose group and the 25 Gy dose group, and the degree of necrosis in the irradiated interventricular septum was more obvious in the 40 Gy dose group as compared with the 25 Gy group. The combined histological analysis of the two groups showed that the necrotic area of the irradiated target area accounted for (26±9)% of the entire interventricular septum area, which was higher than that of the non-irradiated area (0) (P<0.05). There was no damage or necrosis of myocardial tissue outside the target irradiation area in both groups. The results of Masson staining showed that the percentage area of myocardial fibrosis was significantly higher in the irradiated target area than non-irradiated area ((12.6±5.3)% vs. (2.5±0.8)%, P<0.05). Conclusion: SBRT is safe and feasible for irradiating porcine ventricular septum.

Abstract
Objective: BMI may play a protective role in reducing the mortality rate of patients with chronic obstructive pulmonary disease (COPD), but its effect on acute exacerbation of COPD remain unclear. Methods: Subjects were selected from the COPD patients registration system established in 2014 in Pudong new district, Shanghai. COPD patients from 8 communities were selected by cluster sampling and follow up was conducted prospectively for 18 months. Basic information and BMI were obtained from baseline survey, and acute exacerbations were collected during follow-up. The association between BMI and risk of acute exacerbation was evaluated by using multiple negative binomial regression. Results: Among 328 community COPD patients, 295 who completed the follow up were included in the analysis, in whom 96.3% (284/295) were mild COPD patients. During the follow-up, 11.1% (33/295) of the patients reported acute exacerbation. The results of multiple negative binomial regression suggested that, the risk for acute exacerbation decreased with the increase of BMI (IRR=0.85, 95%CI:0.73-0.98), overweight patients with BMI ≥25.0 kg/m2 (IRR=0.36, 95%CI:0.13-0.91) or moderate BMI (T2 vs. T1, IRR=0.31, 95%CI:0.11-0.77) had lower risk for acute exacerbation compared with the patients with normal or low BMI. BMI had a linear correlation with the risk of acute exacerbation. Conclusion: The risk for acute exacerbation in patients with mild or moderate COPD in communities decreased with the increase of BMI, and being overweight might be a protective factor for the acute exacerbation of COPD.

Abstract
Objective: To investigate the correlation between heart rate index (HRI), systolic blood pressure(SBP) peak-to-SBPrest ratio (SBPR) and peak oxygen consumption (peakVO2) in patients with chronic heart failure (CHF), and discuss the possibility of using HRI and SBPR collected during exercise to assess the exercise tolerance of CHF patients in the absence of gas analysis. Methods: In this cross-sectional study, a total of 547 patients with CHF who underwent cardiopulmonary exercise test(CPET) in Tongji Hospital Heart Rehabilitation Center Affiliated to Tongji University from March 2007 to December 2018 were collected retrospectively, focusing on their clinical data including age, gender, type of heart failure,BMI as well as data collected during their CPETs, such as peakVO2, HRI and SBPR. Spearman univariate correlation analysis was used for statistical analysis, to unveil the correlations between peakVO2 and those parameters, and multiple linear regression analysis was also conducted. Results: A total of 547 CHF patients conducting CPET were included in this research, of which 447 were male, at age of 63(56, 69). Univariate analysis indicates that HRI, SBPR and peakVO2 showed significant positive correlation (r=0.323, 0.263, respectively, all P<0.001); Age and peak VO2 showed significant negative correlation(r=-0.207, P<0.001); Male patients showed peakVO2 higher than female(r=-0.229, P<0.001); PeakVO2 of heart failure with reduced ejection fraction(HFrEF) was lower than heart failure with mid-range ejection fraction(HFmrEF)and heart failure with preserved ejection fraction(HFpEF) (r=0.181, P<0.001). Body mass index (BMI) had no significant correlation with peakVO2 (P>0.05). Multivariate linear regression analysis showed that the HRI, SBPR were positively correlated with peakVO2(t=7.68, 5.08, respectively, all P<0.05), while age and BMI showed negative correlation with peakVO2(t=-5.43, -0.31, respectively, all P<0.05). PeakVO2 of male was higher than female(t=-6.03, P<0.05), and peakVO2 of HFrEF was lower than those of HFmrEF and HFpEF(t=3.17, 4.48, respectively, all P<0.05). A linear equation (F=33.52, adjusted R2=0.29) could be constructed: peakVO2=10.65(male) or 8.53(female)+4.26HRI+3.31SBPR-0.07age-0.13BMI+0(HFrEF) or 1.05 (HFmrEF) or 1.62(HFpEF). Conclusion: HRI and SBPR are positively correlated with peakVO2. In the absence of gas analysis, it is possible to apply HRI and SBPR during exercise to predict exercise tolerance in patients with CHF.

Abstract
Objective: To analyze the prevalence and related factors of suicide ideation among nurses in different levels of hospitals in Shandong Province, and to analyze the relationship between them. Methods: From June to July 2020, 1644 nurses in Shandong Province were surveyed by multi-stage stratified cluster sampling. The suicidal ideation of nurses was investigated by suicidal ideation screening. Social support and mental health were measured by the perceived social support scale (pass) and kessler10 scale respectively. The simple coping style scale (SCSQ) was used to evaluate the coping styles of the subjects when they encountered problems. Logistic regression was used to analyze the influencing factors of suicidal ideation, Amos software was used to establish the path model of suicidal ideation related factors, and the maximum likelihood estimation was used to test the path model coefficient. Results: The incidence of suicidal ideation among nurses in secondary hospitals during their career was 8.44%, and that in tertiary hospitals was 11.66%. There was no significant difference in suicidal ideation among nurses at all levels in secondary hospitals (P>0.05) . The main factors related to suicidal ideation were unmarried and others (OR=0.362, 95%CI=0.155, 0.844, P=0.019) , social support (OR=1.084, 95% CI=1.059, 1.109, P=0.000) and mental health status (OR=0.921, 95% CI=0.890, 0.953, P=0.000) . The suicide ideation of skilled nurses in tertiary hospitals was higher than that of other levels (P<0.05) . The related factors of suicide ideation mainly included unmarried and others (OR=0.369, 95% CI=0.214, 0.636, P=0.000) , night shift (OR=1.889, 95%CI=10.57, 3.377, P=0.032) , general self-rated social status (OR=2.377, 95%CI=1.031, 5.483, P=0.042) , physical disease (OR=2.747, 95%CI=1.601, 4.714) , P=0.000) , Social support (OR=0.960, 95%CI=1.042, 1.077, P=0.000) and mental health status (OR=0.942, 95%CI=0.922, 0.963, P=0.000) . Social support and mental health have a direct effect on suicidal ideation. Self-assessment of social status, social support and physical disease can affect suicidal ideation by affecting mental health. Conclusion: It is necessary to pay more attention to the mental health status of nurses at different levels in different hospitals during their career, improve their social support level, and improve their cognition of the practice environment.

Abstract
Objective: To investigate the relationship between the cervical lymph node density (LND) and the prognosis of hypopharyngeal carcinoma. Methods: The clinical and pathological data of 241 patients with hypopharyngeal carcinoma who underwent surgery in Shandong Provincial ENT Hospital from January 2014 to December 2017 were retrospectively analyzed, including 229 males and 12 females, aged 37-81 years. The LND was calculated, i.e. the ratio of the number of lymph nodes with metastasis to the total number of lymph nodes removed. The patients were divided into low LND group and high LND group based on the cutoff value of LND determined by receiver operating characteristic curve (ROC curve). The univariate and multivariate analyses of the disease-free survival (DFS) and the overall survival (OS) were performed in two groups. Results: With the cutoff value of 0.068, 165 patients were in the low LND group (<0.068) and 76 patients in the high LND group (≥0.068). T stage, N stage, maximum lymph node diameter, extracellular invasion of lymph node, and postpharyngeal lymph node metastasis were associated with LND (statistical values were -3.15, -6.82, 23.37, 20.44, and 30.18, respectively, all P values were<0.05). The univariate analysis showed that age, T stage, N stage, maximum diameter of cervical lymph nodes, extracapsular invasion, retropharyngeal lymph node metastasis and LND were the main factors affecting the patients' DFS (χ2=9.31, 7.30, 20.09, 15.30, 9.04, 19.44, 50.27, all P values<0.05) and OS (χ2 were 5.02, 12.94, 18.28, 15.91, 7.95, 16.88, 49.45, all P values<0.05). Multivariate analysis showed that patients with age≤60 years old and LND≥0.068 had reduced DFS [HR values were 0.61 (95%CI 0.43-0.88) and 2.23 (95%CI 1.44-3.45), both P values<0.05]; patients with advanced T stage and LND≥0.068 had reduced OS [HR values were 1.73 (95%CI 1.02-2.93) and 2.39 (95%CI 1.51-3.80), both P values<0.05]. Conclusion: LND is a prognostic factor for patients with hypopharyngeal carcinoma after surgery, with worse prognosis in patients with LND≥0.068.

Abstract
Here, we demonstrate the first example of 3-isothiocyanato thiobutyrolactone serving as a useful building block in the Michael/cyclization reaction with alkylidene pyrazolones for the enantioselective construction of optically active structural bispiro[pyrazolone-thiobutyrolactone] skeletons containing three contiguous stereocenters with two spiroquaternary stereocenters. These products were smoothly afforded in up to 90% yield, >20 : 1 dr and >99% ee with chiral squaramide as the catalyst under mild conditions. Notably, this is also the first example of the merger of a spirocyclic pyrazolone scaffold with a spirocyclic thiobutyrolactone scaffold, potentially useful in medicinal chemistry.

Abstract
Hand, foot, and mouth disease (HFMD) is a common childhood infectious disease caused by various enteroviruses. China has the most significant number of reported cases and deaths of HFMD over the globe. Understanding the epidemic laws of HFMD can provide a scientific basis for designing prevention and control measures. The dynamic transmission models focus on the transmission mechanism of infectious diseases. They can simulate the actual situation to study the epidemic rules of diseases by adding, deleting, and subdividing compartments. More researchers have paid attention to dynamic models because of their high flexibility. To carry out the dynamic model of the HFMD research more effectively, a comprehensive understanding of related research progress in this field is deeply needed. In this paper, based on various researchers' different research purposes of dynamic models, the research progress was classified and summarized, providing meaningful guidance for model construction methods and future research directions and references for dynamic modeling of other models of infectious diseases. It was found that most studies used the SIR dynamic model or its extended model (such as the SEIR model), and few studies contained a complex factor compartment. Some important epidemiological parameters (such as R0) were obtained by studying the HFMD cases in a specific region, simulating different intervention scenarios to evaluate the effect of measures, or revealing the future trend by model prediction. However, there is no dynamic model simultaneously considering age structure, population moving, seasonality and periodicity, and vaccination.

Abstract
Streptococcus thermophilus is a common yogurt starter that consumes lactose as its primary carbon source. The enzyme β-galactosidase is essential for the lactose metabolism and the growth of this species. Streptococcus thermophilus appears to be a promising cell factory. Food-grade vectors have advantages in heterologous protein expression. This study aimed to determine whether the β-galactosidase of S. thermophilus has the α-complementary characteristic and to develop a novel food-grade vector based on this phenomenon. The N-terminal 7 to 36 AA residues of the β-galactosidase in S. thermophilus were deleted. The obtained mutant S. thermophilus Δα lost β-galactosidase activity and growth ability in the lactose medium. Subsequently, plasmids expressing α-fragments with different lengths of 1 to 36 (Sα1), 1 to 53 (Sα2), and 1 to 88 (Sα3) AA were constructed and transformed into S. thermophilus Δα. Recombinant S. thermophilus Δα expressing Sα2 or Sα3 recovered the ability to grow in the lactose medium, and their β-galactosidase activity accounted for 24.5% or 11.5% of the wild strain, respectively. These results indicated that the α-complementation system of β-galactosidase existed in S. thermophilus. Based on the characteristic, a food-grade vector pSEα was constructed. Except for Sα2, vector pSEα expressed the α-donor derived from E. coli β-galactosidase. This facilitated the construction of recombinant plasmids in E. coli DH5α and thus improved the transformation efficiency of S. thermophilus. Green fluorescent protein as a reporter protein could be highly expressed in S. thermophilus using this vector. As a result, pSEα is an efficient and safe vector for S. thermophilus with potential food applications.

Methods: We retrospectively analyzed the clinical data of 56 patients with MF treated with ruxolitinib from July 2017 to December 2020 and applied second-generation sequencing (NGS) technology to detect 127 hematologic tumor-related gene mutations. Additionally, we analyzed the relationship between mutated genes and the efficacy of ruxolitinib. Results: ①Among the 56 patients, there were 36 cases of primary bone marrow fibrosis (PMF) , 9 cases of bone marrow fibrosis (ppv-mf) after polycythemia vera, and 11 cases of bone marrow fibrosis (PET-MF) after primary thrombocytosis (ET) . ②Fifty-six patients with MF taking ruxolitinib underwent NGS, among whom, 50 (89.29%) carried driver mutations, 22 (39.29%) carried ≥3 mutations, and 29 (51.79%) carried high-risk mutations (HMR) . ③ For patients with MF carrying ≥ 3 mutations, ruxolitinib still had a better effect of improving somatic symptoms and shrinking the spleen (P=0.001, P<0.001) , but TTF and PFS were significantly shorter in patients carrying ≥ 3 mutations (P=0.007, P=0.042) . ④For patients carrying ≥ 2 HMR mutations, ruxolitinib was less effective in shrinking the spleen than in those who did not carry HMR (t= 10.471, P=0.034) , and the TTF and PFS were significantly shorter in patients carrying ≥2 HMR mutations (P<0.001, P=0.001) . ⑤Ruxolitinib had poorer effects on spleen reduction, symptom improvement, and stabilization of myelofibrosis in patients carrying additional mutations in ASXL1, EZH2, and SRSF2. Moreover, patients carrying ASXL1 and EZH2 mutations had significantly shorter TTF [ASXL1: 360 (55-1270) d vs 440 (55-1268) d, z=-3.115, P=0.002; EZH2: 327 (55-975) d vs 404 (50-1270) d, z=-3.219, P=0.001], and significantly shorter PFS compared to non-carriers [ASXL1: 457 (50-1331) d vs 574 (55-1437) d, z=-3.219, P=0.001) ; 428 (55-1331) d vs 505 (55-1437) d, z=-2.576, P=0.008]. Conclusion: The type and number of mutations carried by patients with myelofibrosis and HMR impact the efficacy of ruxolitinib.

Abstract
Herein is reported the first example of ring opening and skeletal reconstruction of 3-vinyl benzofuranone-chromones 1 as versatile synthons, which can react with ammonia or primary aliphatic amines as binucleophiles, for the eco-friendly and atom-economical synthesis of diverse and functionalized 2-pyridones 3 with potential biological activity in good to excellent yields (77-93%). When using optically active 1,2-diphenylethylenediamine 2 as the binucleophile, the in situ generated 2-pyridone intermediates are successfully transformed to novel optically active functionalized imidazoline derivatives 4 with high efficiency (up to 87% yield). In particular, this is the first report on the catalyst-free intramolecular cyclization occurring between an amide and a primary aliphatic amine for the construction of imidazoline molecules.

Abstract
Objective: To prospectively compare the efficacy and safety of the greenlight laser anatomical vaporization-incision technique (AVIT) and photoselective vaporization of the prostate(PVP)in the treatment of benign prostatic hyperplasia (BPH). Methods: From November 2019 to September 2020, a randomized controlled study was conducted on 136 BPH patients undergoing greenlight laser surgery in the Department of Urology, the Second Affiliated Hospital of Soochow University. The patient's age ranged from 53 to 85 years and the prostatic volume ranged from 30 to 104 ml. They were divided into two groups by random number table method,including 68 cases of AVIT(observation group)and 68 cases of PVP(control group). The clinical data of the two groups before, during and after operation were collected and analyzed. Results: Operations were successfully completed in the two groups. At 6 months after operation, 63 cases in the observation group and 66 cases in the control group completed the follow-up. There was no significant difference in the prevalence of hypertension, diabetes, coronary heart disease, atrial fibrillation and renal insufficiency between the two groups before operation (all P>0.05). The differences of preoperative age [(66.8±6.5) vs (67.3±5.4) years], international prostate symptom score (IPSS) [(24.2±4.7) vs (23.5±4.5) ], quality of life score (QOL) [4.7(4.1, 4.9) vs 4.6(4.2, 5.0)], peak urinary flow rate (Qmax) [(6.9±2.8) vs (6. 8±2.6) ml/s], post-void residual volume (PVR) [(137(52.8, 190.9) vs 119(70.6, 172.1) ml], prostate volume (PV) [70.5(60.6, 80.9) vs 68.2(61.2, 80.5) ml], serum prostate specific antigen (PSA) [4.4(3.5, 5.1) vs 4.4(3.4, 5.0) ng/ml] were not statistically significant between the two groups (all P>0.05). There was no significant difference in the amount of intraoperative blood loss, catheterization time and the postoperative hospitalization time between the two groups (all P>0.05). Compared with the control group, the operation time and lasing time of the observation group were longer[69.0(64.6, 75.0) vs 55.8(49.1, 63.4) min,(36.3±9.9) vs (31.3±9.3) min], and the intraoperaive laser energy consumption and laser energy density were higher[(297±20) vs (240±20) kJ,(4.50±1.35) vs (3.73±1.17) kJ/ml]. The differences were all statistically significant (all P<0.05). At the follow-up of 1, 3 and 6 months after operation, IPSS and QOL in the observation group were lower than those in the control group, and the differences were all statistically significant (all P<0.05). Qmax in the observation group was higher and PVR was lower than those in the control group, with statistically significant differences (P<0.05). Six months after operation, PV and PSA in the observation group decreased more significantly than those in the control group (56% vs 47%, 70% vs 60%, both P<0.05). No urethral stricture and urinary incontinence occurred in two groups after operation. The incidence rate of urinary tract irritation in the observation group was 6.3%(4/63),lower than the 18.2%(12/66)in the control group (P<0.05). There was no significant difference in the incidence rates of urinary retention, bladder neck contracture and secondary bleeding between the two groups (all P>0.05). Conclusions: Greenlight laser anatomical vaporization-incision technique is safe and effective in the treatment of BPH. Compared with PVP, AVIT has more prostate tissue removed and better curative effect, which is worthy of clinical promotion.

Abstract
Objective: To investigate the role and probable mechanism of miRNA-181a in nonalcoholic fatty liver disease. Methods: HepG2 cells were treated with palmitic acid to construct a nonalcoholic fatty liver disease cell model, and the expression of miR-181a and lipidosis in the cells were measured. Transforming growth factor-β (TGF-β) was used to examine the effect of miR-181a expression in HepG2 cells. The miR-181a, lipidosis, reduced glutathione and reactive oxygen species (ROS) were determined by controlling and regulating the miR-183 expression levels after transfection with miR-181 mimics and inhibitors in HepG2 cells. The miR-181a target genes were predicted by bioinformatics analysis, and verified by real-time fluorescent quantitative PCR and western blotting. The independent sample t-test was used for the comparison between the two independent samples, and the comparison between multiple groups were accorded with the normal distribution, homogeneity of variance, and one-way analysis of variance. Results: Lipidosis was significantly increased after palmitic acid treatment in HepG2 cells, and the expression level of miR-181a was significantly increased than control group. After HepG2 cells were transfected with miR-181a inhibitors, the expression of miR-181a, triglycerides and reactive oxygen species were down-regulated, and reduced glutathione, predicting the mRNA and protein expression of target gene silencing information regulator 2 related enzyme 1 were up-regulated. However, the results were contrary to the above changes after transfection with miR-181a mimics. Conclusion: miR-181a participates in lipidosis and promotes lipid peroxidation in nonalcoholic fatty liver disease. miR-181a may affect the pathogenesis and progression of nonalcoholic fatty liver disease by inhibiting the expression of silencing information regulator 2 related enzyme 1.
