Abstract
BACKGROUND Acne vulgaris is a prevalent skin condition. We have found that some acromegaly patients have acne. However, no study has examined the relationship between acromegaly and acne. OBJECTIVE To explore prevalence and correlation of adult acne in patients with acromegaly. METHODS For this cross-sectional study, we collected questionnaires, clinical information, and laboratory test results of acromegaly patients from January 2022 to December 2022 at Huashan Hospital. Of the 133 questionnaires returned, 123 had valid responses. RESULTS Of the 123 patients with acromegaly enrolled in this study, 54.5% had adult acne. No statistically significant difference was found in prevalence between male and female patients. 61.2% of adult acne patients reported late-onset acne. Late-onset acne patients first developed acne years before acromegaly diagnosis (mean of 5.6 years for male and 4.5 years for female patients). Some acne patients have received traditional anti-acne treatment. Moreover, 31% of the patients reported no improvement, and only 3.5% of patients claimed complete resolution of acne after treatment. Before acromegaly treatment, the prevalence of adult acne was 51.2%, with mild acne accounting for 73.0%, moderate acne accounting for 23.8%, and severe acne accounting for 3.2%. After acromegaly treatment, the prevalence of adult acne was significantly decreased to 37.4% (P = 0.007). An overall decrease in acne severity was noted, with 93.5%, 6.5%, and 0% having mild, moderate, and severe acne, respectively. A total of 83.6% of the patients had self-assessed acne remission, and 33.3% of the patients reported complete acne resolution. However, 9.0% of patients reported that their condition had worsened after acromegaly treatment. After treatment, GH, IGF-1, IGF-1 index, insulin levels, and HOMA-IR decreased significantly in all patients with acromegaly (P < 0.05). Acne remission correlated positively with IGF-1 levels, but not with GH levels. The relationship between acromegaly and acne remains to be elucidated. CONCLUSIONS Our findings provide preliminary evidence of the high prevalence of adult acne in acromegaly patients, and a high rate of late-onset acne as well. Traditional anti-acne treatments are less effective. Acne could be considerably relieved by treating acromegaly. Acne remission positively correlated with IGF-1 decline as well, which revealed the correlation between acne and IGF-1.

Abstract
Objective: To explore the effect of vaccination on viral negative conversion of children with COVID-19. Methods: A retrospective cohort study was conducted. A cohort of 189 children aged 3-14 years with COVID-19 admitted to Renji Hospital (South branch) of Shanghai Jiao Tong University School of Medicine from April 7th to May 19th 2022 was enrolled in the study. According to the vaccination status, the infected children were divided into an unvaccinated group and a vaccinated group. Age, gender, severity, clinical manifestations, and laboratory tests, etc. were compared between groups, by rank sum test or chi-square test. The effects of vaccination on viral negative conversion were analyzed by a Cox mixed-effects regression model. Additionally, a questionnaire survey was conducted among the parents of unvaccinated children to analyze the reasons for not being vaccinated. Results: A total of 189 children aged 3-14 years were enrolled, including 95 males (50.3%) and 94 females (49.7%), aged 5.7 (4.1,8.6) years. There were 117 cases (61.9%) in the unvaccinated group and 72 cases (38.1%) in the vaccinated group. The age of the vaccinated group was higher than that of the unvaccinated group (8.8 (6.8, 10.6) vs. 4.5 (3.6, 5.9) years, Z=9.45, P<0.001). No significant differences were found in clinical manifestations, disease severity, and laboratory results between groups (all P>0.05), except for the occurrence rate of cough symptoms, which was significantly higher in the vaccinated group than in the non-vaccinated group (68.1% (49/72) vs. 50.4% (59/117),χ2=5.67, P=0.017). The Kaplan-Meier survival curve and Cox mixed-effects regression model showed that the time to the viral negative conversion was significantly shorter in the vaccinated group compared with the unvaccinated group (8 (7, 10) vs. 11 (9, 12) d, Z=5.20, P<0.001; adjusted HR=2.19 (95%CI 1.62-2.97)). For questionnaire survey on the reasons for not receiving a vaccination, 115 questionnaires were distributed and 112 valid questionnaires (97.4%) were collected. The main reasons for not being vaccinated were that parents thought that their children were not in the range of appropriate age for vaccination (51 cases, 45.5%) and children were in special physical conditions (47 cases, 42.0%). Conclusion: Vaccination can effectively shorten the negative conversion time of children with COVID-19 and targeted programs should be developed to increase eligible children's vaccination rate for SARS-CoV-2 vaccination.

Abstract
OBJECTIVE To investigate the regulatory role of recombinant Trichinella spiralis cysteine protease inhibitors (rTs-Cys) in induction of polarization of bone marrow-derived macrophages (BMDMs) in vitro. METHODS BMDMs were captured and cultured in conditioned medium for 7 days. Then, mature BMDMs were harvested and assigned into four groups. Cells in Group A (negative control) were given 10 ng/mL IFN-γ combined with 100 ng/mL LPS, cells in Group B (positive control) were treated with IL-4 and IL-10 (at 10 ng/mL both), and cells in Group C (recombinant protein alone) were stimulated with 1 μg/mL rTs-Cys, while cells in Group D (protein co-culture) were simultaneously treated with 1 μg/mL rTs-Cys, 10 ng/mL IFN-γ and 100 ng/mL LPS. Cells and culture supernatant were collected 24 hour post-treatment, and the proportions of F4/80+, CD11b+, CD206+ and CD11c+ cells were detected by flow cytometry. The levels of interleukin IL-6 (IL-6), tumor necrosis factor-α (TNF-α), IL-10 and transforming growth factor-β (TGF-β) in the cell culture supernatant were measured by ELISA and the CD86+ and CD206+ phenotypes were identified by immunofluorescent staining. RESULTS Flow cytometry detected no significant difference in the proportion of F4/80+ CD11b+ CD11c+ cells among the four groups (F = 46.184, P < 0.001), and a lower proportion of F4/80+ CD11b+ CD11c+ cells was seen in groups C and D than in group A (all P values < 0.001). There was a significant difference in the proportion of F4/80+ CD11b+ CD206+ cells among the four groups (F = 11.032, P < 0.001), and a greater proportion of F4/80+ CD11b+ CD206+ cells was seen in groups C and D than in group A (all P values < 0.01). Immunofluorescent staining showed higher CD206+ expression and lower CD86+ expression in groups C and D than in Group A. There were significant differences in the IL-6 and (F = 3.950, P < 0.001) and TNF-α (F = 205.827, P < 0.001) levels in the cell culture supernatants among the four groups, and significantly lower IL-6 and TNF-α levels were measured in groups C and D than in Group A (both P < 0.05). There were significant differences in the IL-10 and (F = 8.274, P < 0.001) and TGF-β (F = 13.559, P < 0.01) levels in the cell culture supernatants among the four groups, and greater IL-10 and TGF-β levels were measured in Group C than in Group A (both P values < 0.01). In addition, the TGF-β level was significantly higher in Group D than in Group A (P < 0.05); however, there was no significant difference in the IL-10 level between groups D and A (P > 0.05). CONCLUSIONS rTs-Cys may induce the polarization of BMDMs to antiinflammatory M2 macrophages in vitro and inhibit the activation of M1 macrophages.

Abstract
Experiments involving scanning electron microscopy of the microstructure of barbules and optical microscopy of knotted barbules were conducted: the behaviour of knotted barbules, and their evolution to form a branch of hooked barbules and unhooked barbules were analysed. A growth model for a feather plume was proposed. MATLAB™ 2-d contour microstructures of sectioned knotted feathers and three-dimensional structural models of barbules were established, moreover, these were analysed using the finite element method. The response under load of different parts of the barbules was obtained. The results showed that there were stress concentrations in feather barbules. The study laid a foundation for finding the internal and external causes of the evolutionary transition of knotted barbules.

Abstract
Objective: To investigate the effect of DNA dependent protein kinase catalytic subunit (DNA-PKcs) on glioma proliferation, invasion and temozolomide sensitivity, and also to explore the potential mechanisms. Methods: Human glioma cell lines H4 and U87 were chosen to carry out RNA interference transfection, and then divided into negative control group (blank group) and siRNA group (test group). The knockdown efficacy of DNA-PKcs siRNA was tested by quantitative PCR and Western blot. The MTS assay and Transwell assay were used to investigate the effect of DNA-PKcs knockdown on glioma cell growth and invasion, respectively. We also used MTS assay to investigate the IC(50) value of temozolomide in negative control group and siRNA groups. Result: Compared with blank group, DNA-PKcs specific siRNA significantly downregulated both mRNA and protein level of DNA-PKcs. MTS assay results demonstrated that 72-hours proliferation of test group were only 52.48%, 54.70% (H4) and 52.98%, 50.45% (U87) of the blank group's counterpart. Transwell assay results showed that the invasiveness abilities of blank and test groups were 1.00±0.03, 0.41±0.05, 0.39±0.04 (H4) and 1.00±0.02, 0.28±0.04, 0.27±0.04 (U87). Moreover, knockdown of DNA-PKcs significantly decreased the temozolomide IC(50) value (H4: 249±27, 97±39, 88±35; U87: 485±41, 86±49, 73±38). Further we applied the Western blot to reveal the mechanism of inhibitory effect of DNA-PKcs knockdown on glioma malignancies and temozolomide sensitivity. We found that downregulation of DNA-PKcs reduced the activity of AKT signal and the expression of its downstream effectors, such as c-Myc, MMP9, and Survivin. Conclusion: RNA interference targeting DNA-PKcs could inhibit glioma malignancies and enhance temozolomide sensitivity. The inhibitory effect of DNA-PKcs knockdown on those biological activities were mainly through inhibition of AKT signal and its downstream effectors.

Abstract
Enterobacter mori, the causal agent of bacterial wilt in mulberry, is becoming a serious disease in mulberry orchards in China. Because no effective control strategy has been devised for this disease, the reliable screening of mulberry material for latent infection became necessary. Hence, a fast polymerase chain reaction (PCR) assay for the detection of E. mori was developed in this study. The primers were designed within regions of the RNA polymerase β-subunit (rpoB) gene. The method is fast and simple and showed 100% sensitivity (no false negatives) and 100% specificity (no false positives), which was tested with 4 representative E. mori strains, 9 Enterobacter type strains, 2 strains of the other major mulberry bacterial pathogens (Ralstonia solanacearum and Pseudomonas syringae pv. mori) in China, 7 strains of other plant-associated pathogens, and 50 unidentified epiphytic bacterial isolates from mulberry plants. The real-time PCR assays reliably detected the DNA at at least 10 fg/μl and the bacterial cells at 102 CFU/ml from mulberry shoots and roots suspension. The strong positive reaction in testing of all symptomatic plants (with 100% positive) and parts of asymptomatic latent infected plant samples (with 36.4% positive) provided proof that this method is reliable and sensitive and suitable for screening plant material with latent infections of E. mori.

Abstract
OBJECTIVE To study the compression factor and clinical manifestation of the compression of the palmar cutaneous branch of the median nerve. METHODS Anatomic study was done on both sides of 2 cadavers and 6 cases of hand injury in the debridement, the origin, course, branch of the palmar cutaneous branch of the median nerve were observed. From 1995 to 1998, 12 patients of compression of the palmar cutaneous branch were treated by local blockade injection. Among them, there were 8 males and 4 females, aged from 23 to 65 years and the course of disease ranged 3 to 12 months. RESULTS The palmar cutaneous branch of the median nerve was (1.3 +/- 0.1) mm in diameter, it could be pulled when the wrist dorsi-extension. All cases showed good recovery of hand function and no recurrence after 4 to 12 months follow-up. CONCLUSION The palmar cutaneous branch compression syndrome is closely related to the local anatomy. The diagnosis is definite according to the clinical symptoms and signs, and local blocking is effective on the most patients.

Abstract
An experiment on rats in vivo with bituminous, anthracitic and brown coal dusts from eight coal mines showed that the fibrogenic degree in experimental rats was related to the free silica contents of the coal dust, which varied from 0.72% to 9.84% in our experiment. Calcium, chromium in coal dust can increase the fibrogenic effect, while aluminum seems to have an antifibrogenic effect. The metamorphic degree of coal has a lesser effect on fibrogenesis than free silica and other mineral elements in coal.

Abstract
Urine and serum ferritin levels were measured by a double-antibody radio-immunoassay in 96 normal adults and 57 patients with urologic malignancies. In the 96 adults, the urine ferritin levels ranged from 0 to 28 ng/ml. Elevated urine ferritin levels were observed in all 7 patients with renal pelvic carcinoma, 4 of 13 patients with renal carcinoma, 1 of 13 patients with well-differentiated (Grade I) bladder carcinoma, 8 of 19 patients with median-differentiated (Grade II) bladder carcinoma, and all 5 patients with poorly-differentiated (Grades III, IV) bladder carcinoma. These results indicated that urine ferritin assay was helpful in discriminating well-differentiated bladder carcinoma from the poorly-differentiated (P less than 0.01) in addition to differentiating renal pelvic carcinoma from renal carcinoma (P less than 0.05).
