Abstract
Objective: To elucidate the epidemiological characteristics and changing trends of liver failure in order to provide evidence-based strategies for prevention and treatment. Methods: The epidemiological information of inpatients with liver failure admitted and treated at Beijing You'an Hospital from 2012 to 2021 was retrospectively collected. The trend test was used to analyze age, gender, as well as the year-by-year changes in the underlying acute and chronic etiology of acute liver failure (ALF), sub-acute liver failure (SALF), acute-on-chronic liver failure (ACLF), and chronic liver failure (CLF). Results: During the study period, information on a total of 8512 inpatients, aged 51.3±13.5 years and mainly male (71.9%) with liver failure, was collected. The highest to lowest proportions of liver failure types were ACLF 4 023 (47.3%), CLF 3 571(42.0%), SALF 670 (7.9%), and ALF 248 (2.9%). The top five causes of liver failure in the overall population, accounting for 87.6% of the total, were hepatitis B 3 199 (37.58%), alcoholic liver disease 2 237 (26.28%), cryptogenic liver disease 906(10.61%), hepatitis B + alcoholic liver disease 603 (7.08%), drugs 488 (5.73%), The top three etiologies of patients with different types of liver failure were acute etiologies for acute liver failure (ALF), followed by drugs 107 (43.1%), hepatitis B 47(19.0%), and unknown etiology 36 (14.5%); sub-acute liver failure (SALF), followed by drugs 381(56.9%), unknown etiology 106 (15.8%), and sepsis 56 (8.4%); and acute-on-chronic liver failure (ACLF), followed by drugs 2 092(52.0%), alcoholic liver disease 813(20.2%), and cryptogenic liver disease 398(9.9%); and chronic etiologies for chronic liver failure (CLF), followed by alcoholic liver disease 1 410(39.5%), hepatitis B 1 028(28.8%), and cryptogenic liver disease 364(10.2%). Longitudinal analysis showed that the average age of patients with liver failure increased year by year, but the sex ratio trend did not change significantly, with male patients predominating throughout. The proportion of drug-induced liver failure in patients with ALF and SALF increased year by year, and the difference in the trend test was statistically significant (P < 0.05). The proportion of patients with chronic etiologies of ACLF and CLF decreased year by year among hepatitis B, while the proportion of alcoholic liver disease, autoimmune liver disease, and cryptogenic liver disease increased year by year (the difference was statistically significant, P < 0.05). Conclusion: The etiological spectrum of liver failure is changing in our country. Although hepatitis B is still the main cause of liver failure, its proportion shows a decreasing trend year by year, with the exception of ACLF, which is no longer the primary etiology of other types of liver failure, while drug-induced liver disease, alcoholic liver disease, autoimmune liver disease, and cryptogenic liver disease are increasing year by year and will become the focus of liver disease prevention and treatment in the future.

Abstract
Objective: To investigate the regulative effects of Streptococcus mutans (Sm) antisense vicK RNA (ASvicK) on the multi-species biofilm formed by three common oral streptococci (Sm, Streptococcus sanguinis, and Streptococcus gordonii) (Sm+Ss+Sg). Methods: ASvicK over-expression strain was constructed by using a recombinant plasmid, and three-species biofilm UA159+Ss+Sg and ASvicK+Ss+Sg were cultured. The phenotypes of biofilms were detected by scanning electron microscopy (SEM). Crystal violet (CV) assay was used to detect biofilm biomass. Lactate kit and anthrone-sulfuric acid colorimetric assay were used to determine the abilities of lactic acid and exopolysaccharides production, respectively. The proportions of three-species and expression levels of the cariogenic-related genes in biofilms were detected by TaqMan fluorescence quantitative PCR and real-time fluorescence quantitative PCR. A biofilm demineralization model of human enamel slabs was further constructed, and the hardness of enamel surface was detected. Results: Compared to UA159+Ss+Sg, over-expression of ASvicK could inhibit biofilm formation and lactic acid production in ASvicK+Ss+Sg biofilm significantly decreased by 78.93% (P<0.001) and 62.23% (P<0.001), respectively. With ASvicK over-expression, the amounts of water-insoluble and-soluble glucoses in ASvicK+Ss+Sg biofilm were reduced respectively by 39.13% (P<0.001) and 68.00% (P<0.001). Compared to the UA159+Ss+Sg Group, the proportion of Sm, the cariogenic bacteria, showed 33.00% reduction (P<0.01) in Sm+Ss+Sg biofilm, and the gene expressions of cariogenic-relative genes vicK/X, gtfB/C/D, and ftf significantly decreased (P<0.05). The micro-hardness value of enamel slabs after demineralization by ASvicK+Ss+Sg biofilm was significantly increased to 183.84% (P<0.001). Conclusions: ASvicK over-expression could reduce the Sm proportion and weaken the cariogenicity of oral Streptococcus biofilm, thereby possibly slowing down the progression of caries.

Abstract
Objective: To investigate the levels of sex hormone and fertility in female patients after hematopoietic stem cell transplantation (HSCT), as well as their correlation with conditioning regimens, and analyse the effect of hormone replacement therapy (HRT) in young women after HSCT. Methods: Retrospective case series study. The clinical data of 147 women who underwent HSCT in the First Affiliated Hospital of Soochow University from January 2010 to January 2021 were retrospectively analyzed. The sex hormone levels were measured and followed-up, and the survival, menstrual fertility and the use of HRT of the patients were also followed-up. The sex hormone levels were measured after transplantation, and the ovarian function was evaluated. Independent sample t test and χ2 test were used for comparison between the two groups. Results: The median age of the 147 patients was 26 (range, 10-45) years. Of them, 135 patients received allogeneic HSCT and 12 patients received autologous HSCT. Furthermore, 129 patients received myeloablative conditioning, and 18 patients received reduced conditioning dose. The median follow-up time was 50 months (range, 18-134 months). Five patients died of disease recurrence during follow-up. Of the 54 patients with subcutaneous injection of zoladex, three recovered menstruation spontaneously after transplantation, and all of them were myeloablative conditioning patients, one patient gave birth to twins through assisted reproductive technology. Ninety-three patients did not use zoladex before conditioning, two patients with aplastic anemia with non-myeloablative transplantation resumed menstruation spontaneously, and conceived naturally. The level of follicle stimulating hormone after transplantation in patients receiving myeloablative conditioning regimen was significantly higher than that in patients receiving reduced-dose conditioning regimen [(95.28±3.94) U/L vs. (71.85±10.72) U/L, P=0.039]. Among 147 patients, 122 patients developed premature ovarian failure, 83 patients received sex hormone replacement therapy after transplantation, and 76 patients recovered menstruation and improved endocrine function. Conclusions: The incidence of premature ovarian failure is high in female patients after HSCT, and patients have a chance at natural conception. Reducing the dose of conditioning regimen and the application of zoladex before transplantation can reduce ovarian of conditioning drugs. HRT after transplantation can partially improve the endocrine function of patients.

Abstract
Objective: To compare the impact of different prognostic scores in patients with acute-on-chronic liver failure (ACLF) in order to provide treatment guidance for liver transplantation. Methods: The information on inpatients with ACLF admitted at Beijing You'an Hospital Affiliated to Capital Medical University and the First Affiliated Hospital of Zhejiang University School of Medicine from January 2015 to October 2022 was collected retrospectively. ACLF patients were divided into liver transplantation and non-liver transplantation groups, and the two groups prognostic conditions were followed-up. Propensity score matching was carried out between the two groups on the basis of liver disease (non-cirrhosis, compensated cirrhosis, and decompensated cirrhosis), the model for end-stage liver disease incorporating serum sodium (MELD-Na), and ACLF classification as matching factors. The prognostic condition of the two groups after matching was compared. The difference in 1-year survival rate between the two groups was analyzed under different ACLF grades and MELD-Na scores. The independent sample t-test or rank sum test was used for inter-group comparison, and the χ (2) test was used for the comparison of count data between groups. Results: In total, 865 ACLF inpatients were collected over the study period. Of these, 291 had liver transplantation and 574 did not. The overall survival rates at 28, 90, and 360 days were 78%, 66%, and 62%, respectively. There were 270 cases of matched ACLF post-liver transplantation and 270 cases without ACLF, in accordance with a ratio of 1:1. At 28, 90, and 360 days, patients with non-liver transplantation had significantly lower survival rates (68%, 53%, and 49%) than patients with liver transplantation (87%, 87%, and 78%, respectively; P < 0.001). Patients were classified into four groups according to the ACLF classification criteria. Kaplan-Meier survival analysis showed that the survival rates of liver transplantation and non-liver transplantation patients in ACLF grade 0 were 77.2% and 69.4%, respectively, with no statistically significant difference (P = 0.168). The survival rate with an ACLF 1-3 grade was significantly higher in liver transplantation patients than that of non-liver transplantation patients (P < 0.05). Patients with ACLF grades 1, 2, and 3 had higher 1-year survival rates compared to non-liver transplant patients by 50.6%, 43.6%, and 61.7%, respectively. Patients were divided into four groups according to the MELD-Na score. Among the patients with a MELD-Na score of < 25, the 1-year survival rates for liver transplantation and non-liver transplantation were 78.2% and 74.0%, respectively, and the difference was not statistically significant (P = 0.149). However, among patients with MELD-Na scores of 25-30, 30-35, and≥35, the survival rate was significantly higher in liver transplantation than that of non-liver transplantation, and the 1-year survival rate increased by 36.4%, 54.9%, and 62.5%, respectively (P < 0.001). Further analysis of the prognosis of patients with different ACLF grades and MELD-Na scores showed that ACLF grades 0 or 1 and MELD-Na score of < 30 had no statistically significant difference in the 1-year survival rate between liver transplantation and non-liver transplantation (P > 0.05), but in patients with MELD-Na score≥30, the 1-year survival rate of liver transplantation was higher than that of non-liver transplantation patients (P < 0.05). In the ACLF grade 0 and MELD-Na score of≥30 group, the 1-year survival rates of liver transplantation and non-liver transplantation patients were 77.8% and 25.0% respectively (P < 0.05); while in the ACLF grade 1 and MELD-Na score of≥30 group, the 1-year survival rates of liver transplantation and non-liver transplantation patients were 100% and 20.0%, respectively (P < 0.01). Among patients with ACLF grade 2, the 1-year survival rate with MELD-Na score of < 25 in patients with liver transplantation was 73.9% and 61.6%, respectively, and the difference was not statistically significant (P > 0.05); while in the liver transplantation patients group with MELD-Na score of ≥25, the 1-year survival rate was 79.5%, 80.8%, and 75%, respectively, which was significantly higher than that of non-liver transplantation patients (36.6%, 27.6%, 15.0%) (P < 0.001). Among patients with ACLF grade 3, regardless of the MELD-Na score, the 1-year survival rate was significantly higher in liver transplantation patients than that of non-liver transplantation patients (P < 0.01). Additionally, among patients with non-liver transplantation with an ACLF grade 0~1 and a MELD-Na score of < 30 at admission, 99.4% survived 1 year and still had an ACLF grade 0-1 at discharge, while 70% of deaths progressed to ACLF grade 2-3. Conclusion: Both the MELD-Na score and the EASL-CLIF C ACLF classification are capable of guiding liver transplantation; however, no single model possesses a consistent and precise prediction ability. Therefore, the combined application of the two models is necessary for comprehensive and dynamic evaluation, but the clinical application is relatively complex. A simplified prognostic model and a risk assessment model will be required in the future to improve patient prognosis as well as the effectiveness and efficiency of liver transplantation.

Abstract
Objective: To investigate the application of sentinel lymph node biopsy (SLNB) in early-staged cervical cancer by laparoscopy. Methods: It was a prospective, single-arm, single-center clinical study. Seventy-eight cases of cervical cancer patients were collected from July 2015 to December 2018 at the Fourth Hospital of Hebei Medical University. All the patients were injected with tracer into the disease-free block of cervical tissue after anesthesia by the same surgeon who learned sentinel lymph node (SLN) mapping technique in Memorial Sloan-Kettering Cancer Center, and underwent SLN mapping followed by complete pelvic lymphadenectomy. Moreover, all the dissected lymph nodes were stained with hematoxylin eosin staining (HE) pathological examination. Besides, the negative SLN on hematoxylin-eosin staining were detected by immunohistochemistry cytokeratin staining micro-metastasis. To analyze the distribution, detection rate, false negative rate the sensitivity and negative predictive value of the SLN in early-staged cervical cancer by laparoscopy, and explore the value of SLN mapping in predicting the lymph nodes metastasis in early-staged cervical cancer. Results: The overall detection rate of SLN in cervical cancer was 99% (77/78), bilateral detection rate was 87% (68/78). The average of 12.4 lymph node (LN) and 3.6 SLN were dissected for each patients each side. SLN of cervical cancer were mainly distributed in the obturator space (61.5%, 343/558), followed by external iliac (23.5%, 131/558), common iliac (7.3%, 41/558), para-uterine (3.8%, 21/558), internal iliac (2.2%, 12/558), para abdominal aorta (1.1%, 6/558), and anterior sacral lymphatic drainage area (0.7%, 4/558). Fourteen cases of LN metastasis were found among all 78 cases. There were a total of 38 positive LN, including 26 SLN metastasis and 12 none sentinel LN metastasis. Through immunohistochemical staining and pathological ultra-staging, 1 SLN was found to be isolated tumor cells (ITC), and 5 SLNs were found to be micro-metastases (MIC), accounting for 23% (6/26) of positive SLN. SLN mapping with pathological ultra-staging improved the prediction of LN metastasis in cervical cancer (2/14). Metastatic SLN mainly distributed in the obturator space (65%, 17/26), peri-uterine region (12%, 3/26), common iliac region (15%, 4/26), and external iliac region (8%, 2/26). The consistency of the diagnosis of lymph node metastasis by SLN biopsy and postoperative retroperitoneal lymph node metastasis showed that the Kappa value was 1.000 (P<0.001), indicated that the metastasis status of SLN and retroperitoneal lymph node were completely consistent. The sensitivity, specificity, accuracy, false-negative rate, and negative predictive value of SLN biopsy in the diagnosis of lymph node metastasis were 100%, 100%, 100%, 0, and 100%, respectively. Conclusions: SLN in early-staged cervical cancer patients were mainly distributed in the obturator and external iliac space, pathalogical ultra-staging of SLN could improve the prediction of LN metastasis. Intraoperative SLN mapping is safe, feasible and could predict the state of retroperitoneal LN metastasis in early-staged cervical cancer. SLNB may replace systemic pelvic lymphadenectomy.

Abstract
Objective: To compare the efficacy, advantages and disadvantages of endoscopic CO2 laser cauterization (ECLC) and open neck surgery in the treatment of congenital pyriform sinus fistula (CPSF). Methods: From September 2014 to March 2017, 80 cases with confirmed diagnosis of CPSF received initial treatment at Guangdong Provincial People's Hospital were prospectively analyzed, including 34 males and 46 females, aged 18 to 672 (194.17±141.18) months. They were consecutively divided into endoscopic group and open-surgery group, with 40 cases in each group. Both groups of patients received surgical treatment under general anesthesia. The endoscopic group was treated by endoscopic CO2 laser cauterization, and the open-surgery group underwent the following surgery: first, we performed suspension laryngoscopy examination to confirm the presence of fistula in the bottom of the piriform fossa, then open-neck resection of congenital piriform sinus fistula with recurrent laryngeal nerve and/or lateral branch of superior laryngeal nerve anatomy plus partial thyroidectomy were performed. The data between the two groups were compared, including the operative time, intraoperative blood loss, postoperative pain, average length of stay, neck cosmetic scores, complications and cure rates. All patients were followed up in outpatient clinics. Statistical analysis was performed using SPSS 20.0 software. P<0.05 indicates that the difference is statistically significant. Results: All patients were successfully completed the operation. The operative time, intraoperative blood loss, postoperative pain and average length of hospital stay in the endoscopic group were significantly less than those in the open group [(27.4±5.5) min to (105.8±52.5) min, (0.6±0.5) ml to (33.6±41.5) ml, (1.7±0.9) points to (4.6±0.7) points, (5.9±2.9)d to(8.9±3.3)d, t values were-9.400, -5.031, -16.199, -4.293, P values were all<0.01]; The neck cosmetic score in the endoscopy group was significantly greater than that of the open group [(9.9±0.4) against (5.8±0.9) points, t=25.847, P<0.01]. Compared with the open group (15.0%, 6/40), the complication rate of the endoscopic group (7.5%, 3/40) was not statistically significant (χ²=0.50, P>0.05). Three months after the first treatment, the cure rate in the endoscopic group (82.5%, 33/40) was significantly lower than that in the open-neck group (100.0%, 40/40), χ²=5.64, P<0.05. The follow-up time was 12 months after the last treatment. Eighty cases were followed up and none was lost to follow-up. During the follow-up period, the cure rate of the endoscopy group (97.5%, 39/40) was compared with that of the open group (100.0%, 40/40), and the difference was not statistically significant. Conclusions: In the treatment of CPSF, the two-surgical method each has their advantages. Compared with open-neck surgery, ECLC is simpler, repeatable. ECLC has shorter time in operation and hospital stay, less complications, and less postoperative pain and more precise cosmetic results. It could be preferred for the initial treatment of CPSF and relapsed cases after cauterization. But subject to relatively low cure rate of one-time cauterization and uncertain long-term efficacy, it cannot completely replace the open-neck surgery at present.

Abstract
Objective: To investigate the survival and prognosis of B-lineage acute lymphoblastic leukemia (B-ALL) patients with TP53 mutation. Methods: The clinical data of 479 newly diagnosed B-ALL patients treated in the First Affiliated Hospital of Soochow University from January 2016 to December 2019 were retrospectively analyzed. Results: Among 479 B-ALL patients, 34 cases (7.1%) were positive for TP53 gene mutation, and a total of 36 TP53 mutations were detected, including 10 frameshift gene mutations (27.8%) , 23 missense mutations (63.9%) and 3 nonsense mutations (8.3%) . A total of 34 (94.4%) mutations were located in the DNA binding domain (exons 5-8) .The average number of mutated genes in patients with TP53 gene mutation (2.3) and the group without TP53 gene mutation (1.1) were statistically different (P<0.001) . The proportion of Ph positive and Ph-like positive patients in the TP53 gene mutation negative group was significantly higher than that of the TP53 mutation positive group, and the difference was statistically significant (P<0.001) . The 3-year OS and EFS rates of the TP53 gene mutation negative group were significantly higher than those of the TP53 gene mutation positive group. The differences in OS and EFS rates between the two groups were statistically significant (χ(2)= 4.694, P = 0.030; χ(2)= 5.080, P= 0.024) . In the multivariate analysis, failure to achieve remission (CR) after one course of induction chemotherapy was an independent adverse prognostic factor affecting OS.Of the 34 patients with TP53 mutation, 16 underwent allogeneic hematopoietic stem cell transplantation (allo-HSCT) in the CR(1) state, and 2 patients with recurrence after transplantation obtained CR(2) after infusion of donor-derived anti-CD19 chimeric antigen receptor T (CAR-T) cells. Among the 11 patients with TP53 gene mutation who relapsed during consolidation chemotherapy, 6 received anti-CD19 CAR T cell therapy, 4 patients achieved remission and minimal residual disease (MRD) turned negative, followed by bridging allo-HSCT, and 2 of them sustained CR. Conclusion: Missense mutations are the most common in B-ALL patients with TP53 gene mutation, and the majority of mutations were located in the DNA binding domain. B-ALL patients with TP53 gene mutation should undergo allo-HSCT as soon as possible after CAR-T cell therapy has cleared the MRD after recurrence. B-ALL patients with TP53 gene mutation still have a higher recurrence rate after allo-HSCT, and the infusion of donor-derived CAR-T cells can achieve better sustained remission.

Abstract
Objective: To understand the influence and lag effect of meteorological factors on the incidence of hand, foot and mouth disease (HFMD) in Shijiazhuang. Methods: The daily incidence data of HFMD in Shijiazhuang during 2017-2019 were collected from Chinese Information System for Disease Control and Prevention. The hourly meteorological data were collected form meteorological stations of Shijiazhuang of Chinese meteorological data network. The distributed lag nonlinear model was built for statistical analysis by software R 3.6.2. Results: When the daily average temperature was 15-26 ℃, the risk of incidence of HFMD increased at lag 3-6 days. However, the risk was highest when the temperature was 25 ℃ at lag 3 days (RR=1.03,95%CI:1.00-1.06). When the daily average relative humidity was more than 80%, the risk of incidence of HFMD increased at lag 5-18 days. However, the risk was highest at lag 9 days (RR=1.04, 95%CI: 1.02-1.06).When the daily average air pressure ranged from 999 hPa to 1 007 hPa, the risk of incidence of HFMD increased at lag 5-8 days. However, the risk was highest at lag 6 days (RR=1.01, 95%CI: 1.00-1.02).When the daily average precipitation ranged from 15 to 32 mm, the risk of incidence of HFMD increased at lag 3-18 days. However, the risk was highest at lag 6 days (RR=1.11, 95%CI: 1.02-1.19). Conclusions: Meteorological factors increased the risk of incidence of HFMD such as higher daily average temperature (15-26 ℃), higher daily average humidity (>80%), lower daily average air pressure (999-1 007 hPa) and higher daily average precipitation (15-32 mm) in Shijiazhuang during 2017-2019. They were all correlated with the incidence of HFMD with certain lag days. It is suggested to use these meteorological indicators for the early warning of HFMD.

Abstract
This study was conducted to evaluate the effects and combinational effects of Bacillus subtilis (BS) and montmorillonite (MMT) on laying performance, gut mucosal oxidation status, and intestinal immunological and physical barrier functions of laying hens. Three hundred sixty laying hens (29-week-old) were randomly assigned to a 2 × 2 factorial arrangement of treatments (n = 6) for 10 wk as follows: (1) basal diet; (2) the basal diet plus 5 × 108 cfu BS/kg; (3) the basal diet plus 0.5 g MMT/kg; and (4) the basal diet plus 5 × 108 cfu BS/kg and 0.5 g MMT/kg. Dietary supplementation with BS increased egg production and egg mass, the activities of catalase (CAT) and total superoxide dismutase in the intestinal mucosa, and villus height and villus height-to-crypt depth ratio of the jejunum (P < 0.05) but downregulated the mRNA expression levels of toll-like receptor 4 and myeloid differentiation factor 88 (MyD88) in the duodenum and jejunum, interleukin 1 beta in the duodenum, and nuclear factor kappa B P65 (NF-κB P65) and tumor necrosis factor alpha in the jejunum (P < 0.05). Dietary supplementation with MMT increased egg production and egg mass, the concentration of secretory immunoglobulin A in the duodenum, and the occludin mRNA expression level in the jejunum (P < 0.05) but reduced feed conversion ratio, malondialdehyde concentration in the duodenum and jejunum, and the mRNA expression level of MyD88 in the jejunum (P < 0.05). In addition, there was an interaction effect between BS and MMT supplementation on the CAT activity and the MyD88 mRNA expression level in the duodenum and the mRNA expression level of occludin in the jejunum (P < 0.05). In conclusion, dietary BS and MMT and their combination may improve the intestinal health status of laying hens, which may contribute to the increase in hens' laying performance.

Abstract
Objective: To observe content of cytokine in human stromal vascular fraction gel (SVF-GEL) and effect of SVF-GEL on biological behaviors of epidermal and dermal cells in vitro and clinical efficacy of SVF-GEL. Methods: (1) SVF-GEL was prepared using liposuction aspirates harvested from females who received abdomen liposuction in author's unit. SVF-GEL (1 mL) and high-glucose Dulbecco's modified eagle medium (DMEM, 1 mL) were respectively cultured for 24 h with high-glucose DMEM containing 10% fetal calf serum, 10 g/L penicillin, and 10 g/L streptomycin, denoted as SVF-GEL group and negative control group, with 6 samples in each group. Content of epidermal growth factor (EGF) and vascular endothelial growth factor (VEGF) in the supernatant was determined by enzyme-linked immunosorbent assay. (2) A number of 5×10(5) human skin fibroblasts (HSF) and HaCaT cells in logarithmic phase were inoculated and cultured in Transwell chambers for 12 h. All Transwell chambers containing cells were divided into SVF-GEL group (0.5 mL SVF-GEL was added for co-culture) and control group (0.5 mL high-glucose DMEM was added for co-culture), with 9 samples in each group for HSF and HaCaT cells. Scratch assay was performed after culture for 24 h, and residual scratch width was observed at post scratch hour (PSH) 0 (immediately), 24, and 48. Cell migration distance was measured at PSH 24 and 48. After culture for 24, 48, and 72 h, the number of living cell was counted using cell counter. (3) From June 2018 to June 2019, SVF-GEL was applied clinically to treat 15 patients with depressed scars on face, including 2 males and 13 females, aged 19 to 42 years. Survival condition of SVF-GEL and whether complications or not were observed 6 months after surgery. Before surgery and 6 months after surgery, depressed degree, color, and pliability of scar were compared. Vancouver Scar Scale (VSS) was employed to access color, vascularity, and pliability before surgery and 6 months after surgery, and total score was calculated. The number of patients with complete satisfaction or satisfaction was counted six months after surgery. Data were processed with analysis of variance of factorial design, paired samples t test, and Wilcoxon rank sum test. Results: (1) The content of EGF in SVF-GEL group and negative control group was (316.6±12.8) and (3.4±0.6) pg/mL, and the content of VEGF in SVF-GEL group and negative control group was (568.67±12.19) and (4.93±0.16) pg/mL, with statistically significant differences between the two groups (t=48.777, 92.485, P<0.01). (2) Residual scratch widths of HSF and HaCaT in SVF-GEL group and control group were decreased gradually along with time elapse, in which those in SVF-GEL group at PSH 24 and 48 were less than those in control group. At PSH 24 and 48, cell migration distances of HSF and HaCaT in SVF-GEL group were more than those in control group (t(HSF)=-20.304, -43.516, t(HaCaT)=-15.060, -8.684, P<0.01). After culture for 24, 48, and 72 h, the number of living cell of HSF and HaCaT in SVF-GEL group was significantly more than that in control group (t(HSF)=-3.374, -6.809, -18.036, t(HaCaT)=-4.793, -6.028, -8.141, P<0.05 or P<0.01). (3) Six months after surgery, SVF-GEL grafted into patients survived well without complications, and depressed degree of scar ameliorated obviously with lightened pigmentation and softer texture as compared with before surgery. Compared with those before surgery, VSS scores of color, vascularity, and pliability, and total score of 15 patients with depressed scars on face were obviously decreased 6 months after surgery (Z=-2.06, -2.07, -2.07, t=-15.811, P<0.05 or P<0.01). One patient was satisfied with the clinical outcome, and the rest 14 patients were completely satisfied with the clinical outcomes. Conclusions: SVF-GEL contains cytokines EGF and VEGF, which can enhance cell migration ability and proliferation ability of HSF and HaCaT cells and have obvious effects on depressed scars for clinical application.

Abstract
Objective: To investigate the prevalence of work-related musculoskeletal disorders (WMSDs) among sonographers in a province of China and influencing factors for WMSDs, and to provide a practical basis for the prevention and treatment of WMSDs in sonographers. Methods: From November 2016 to February 2017, stratified cluster sampling was used to select 700 sonographers from 50 hospitals in this province. A self-designed questionnaire for WMSDs in sonographers was used to investigate general data and the prevalence of WMSDs, and the influencing factors for the prevalence of WMSDs were analyzed. Results: The prevalence rate of WMSDs among these sonographers was 80.22%, and the prevalence rates of WMSDs in the shoulder, the neck, the waist, the back, the wrist, the elbow, the hip, the knee, and the ankle were 74.55%, 68.87%, 63.44%, 57.26%, 53.16%, 45.22%, 37.88%, 30.44%, and 29.24%, respectively. There was a significant difference in the prevalence rate of WMSDs between the sonographers with different ages and working years, and the prevalence rate of WMSDs tended to increase with the increase in age and working years (χ(2)=20.86 and 18.52, P<0.01) . The multivariate logistic regression analysis showed that female sex (odds ratio [OR]=1.798) , working years >16 (OR=1.004) , weekly working hours >40 (OR=1.616) , poor physical conditions (OR=1.690) , and high work fatigue (OR=1.302) were risk factors for WMSDs in sonographers. Conclusion: There are high prevalence rates of WMSDs in the shoulder, the neck, the waist, the back, the wrist, and the elbow. Sonographers should strengthen self-protection awareness, and effective preventive measures should be adopted to reduce the prevalence rate of WMSDs.

Abstract
Objective: To systematically analyze the innovation and development trend in the field of ophthalmology. Methods: The latest ophthalmology funding program from the National Eye Institute and National Natural Science Foundation of China, and funding project for 2012 to 2016 from the National Institutes of Health, National Natural Science Foundation of China and National key research and development plan of China was collected. Using the comparative analysis method, the major ophthalmology funding areas at home and abroad were analyzed. Papers published in 2012 to 2016 in the field of ophthalmology were collected from the Web of Science Core Collection, among which ESI highly cited papers and hot papers were particularly selected. Using bibliometric methods, the time trend of the number of papers and the citation frequency were analyzed. Using the co-occurrence cluster analysis method, the continued focuses and emerging concerns of ophthalmology papers was analyzed. Results: The funding plan of the National Eye Institute mainly covers nine major diseases in ophthalmology. NSFC focuses on retinal damage and repair mechanisms. The National Key Research and Development Program of China focuses on research on high-end ophthalmic implants. NIH continues to focus on the molecular mechanisms of blinding eye disease such as diabetic retinopathy, age-related macular degeneration, glaucoma, corneal disease and cataracts, basic research in genetics, and advanced diagnostic techniques such as imaging. Latest areas of interest involve gene editing techniques and the application of stem cell technology in ophthalmology. In China, research and application of stem cells in ophthalmic diseases, intraocular sustained-release drug carrier, and precision medicine research in ophthalmology are emerging areas of funding. In 2012 to 2016, research topics of 168 papers collected by ESI focused on macular degeneration, retinal diseases, glaucoma and other eye diseases. How to quickly promote new drugs and new technological achievements to the clinical application is a problem in the field of ophthalmology. How to change the ophthalmology clinic model, so as to provide patients with convenient and quality service, has become a research topic that needs to be given attention to. Conclusions: Based on the multidimensional analysis of innovation and development in the field of ophthalmology, cross application and integration of ophthalmology and high - tech fields such as advanced imaging technology, stem cell technology, gene editing technology, molecular targeting, and artificial intelligence will provide a strong basis for the enhancement of China's ophthalmology research innovation and international competitiveness. Research efforts for ophthalmic transformation should be strengthened, in order to realize the clinical application of the achievements as soon as possible. (Chin J Ophthalmol, 2018, 54: 452-463).

Abstract
Background FK506-binding proteins (FKBPs) have become the subject of considerable interest in several fields, leading to the identification of several cellular and molecular pathways in which FKBPs impact prenatal development and pathogenesis of many human diseases. Main body This analysis revealed differences between how mammalian and Drosophila FKBPs mechanisms function in relation to the immunosuppressant drugs, FK506 and rapamycin. Differences that could be used to design insect-specific pesticides. (1) Molecular phylogenetic analysis of FKBP family proteins revealed that the eight known Drosophila FKBPs share homology with the human FKBP12. This indicates a close evolutionary relationship, and possible origination from a common ancestor. (2) The known FKBPs contain FK domains, that is, a prolyl cis/trans isomerase (PPIase) domain that mediates immune suppression through inhibition of calcineurin. The dFKBP59, CG4735/Shutdown, CG1847, and CG5482 have a Tetratricopeptide receptor domain at the C-terminus, which regulates transcription and protein transportation. (3) FKBP51 and FKBP52 (dFKBP59), along with Cyclophilin 40 and protein phosphatase 5, function as Hsp90 immunophilin co-chaperones within steroid receptor-Hsp90 heterocomplexes. These immunophilins are potential drug targets in pathways associated with normal physiology and may be used to treat a variety of steroid-based diseases by targeting exocytic/endocytic cycling and vesicular trafficking. (4) By associating with presinilin, a critical component of the Notch signaling pathway, FKBP14 is a downstream effector of Notch activation at the membrane. Meanwhile, Shutdown associates with transposons in the PIWI-interacting RNA pathway, playing a crucial role in both germ cells and ovarian somas. Mutations in or silencing of dFKBPs lead to early embryonic lethality in Drosophila. Therefore, further understanding the mechanisms of FK506 and rapamycin binding to immunophilin FKBPs in endocrine, cardiovascular, and neurological function in both mammals and Drosophila would provide prospects in generating unique, insect specific therapeutics targeting the above cellular signaling pathways. Conclusion This review will evaluate the functional roles of FKBP family proteins, and systematically summarize the similarities and differences between FKBP proteins in Drosophila and Mammals. Specific therapeutics targeting cellular signaling pathways will also be discussed.

Abstract
Objective: To evaluate the value of radial and ulnar arteries hemodynamic changes by ultrasound in patients with primary palmar hyperhidrosis after thoracic sympathetic block. Methods: This was a prospective study, from January 2016 to September 2016, 23 patients with primary palmar hyperhidrosis were admitted to the First Hospital of Jiaxing City, Zhejiang Province, 92 arteries of these patients who underwent thoracic sympathetic block were enrolled into this study. Diameters, peak systolic velocity (PSV), end diastolic velocity (EDV) and resistive index (RI) of the radial and ulnar arteries were examined one day before and after the operation by color Doppler ultrasound. Spectral waveforms of these arteries were observed, and palms temperature (T), oxygen saturation (SpO(2)), perfusion index (PI) were also measured. Diameters, PSV, EDV, RI, T, SpO(2) and PI of the patients with PH were compared before and after the surgery. The effect of operation was also evaluated. Results: Before surgery, diameters and EDV of the radial and ulnar arteries of the patients with PH were(2.12±0.36) mm, (1.50±0.32) mm, (4.90±1.84) cm/s, (4.71±1.65) cm/s, respectively, after surgery, the diameter of the RA, UA and EDV were (2.45±0.54) mm, (1.87±0.44) mm, (9.37±1.69) cm/s and (9.12±1.54) cm/s, which were significantly increased.Before surgery, RI of the RA and UA of the patients were (0.85±0.05), (0.97±0.07) , respectively, after surgery, RI of the RA and UA were (0.57±0.04), (0.64±0.09), respectively, which were significantly decreased after surgery. The difference was statistically significant (t=-5.23, -2.33, -19.80, -14.68, 3.31, 3.48, all P<0.01). Before surgery, PSV of the RA and UA of the patients were (46.38±15.12) cm/s, (45.60±14.88) cm/s , respectively, after surgery, PSV of the RA and UA were (46.93±16.02) cm/s, (46.19±15.30) cm/s , respectively. The difference was not statistically significant (t=-0.23, -1.39, all P>0.05). Before surgery, T, SpO(2) and PI of the patients were(29.7±1.04) ℃, (93.24±2.23) %, (1.11±0.13) % , respectively, after surgery, T, SpO(2) and PI of the patients were (35.09±1.21) ℃, (98.10±1.34) %, (4.77±1.22)% , respectively. The difference was statistically significant (t=-20.174, -1.140, -23.601, all P<0.05). The symptoms of hyperhidrosis of the patients were disappeared immediately after the surgery in both hands. All of the patients were cured within 3 months and there was no severe complications. Conclusion: Thoracic sympathetic block increase Diameters and EDV but decrease RI of the radial and ulnar arteries of the patients with PH and increase the palms temperature. Artery diameters, EDV, and RI measured by ultrasound can be used as parameters to evaluate the effect of thoracic sympathetic block in patients with PH. It's objective, non-invasive and convenient.

Abstract
Previous studies examining the association between interleukin-6 (IL-6) -174G/C polymorphism and psoriasis risk have produced inconsistent results. The aim of this study was to offer a comprehensive review of the association between IL-6 -174G/C polymorphism and psoriasis risk through a meta-analysis. Literature search of PubMed and Embase databases was conducted to identify all eligible studies published before October 29, 2015. Four case-control studies involving 651 psoriasis cases and 552 controls were included in this meta-analysis. Data were extracted, and pooled odds ratios (ORs) with 95% confidence intervals (CIs) were calculated to assess the associations. Combined analysis revealed a significant association between this polymorphism and psoriasis risk under the recessive model (OR = 1.69, 95%CI = 1.12-2.55, P = 0.013 for GG vs GC + CC), and the heterozygous comparison model (OR = 1.70, 95%CI = 1.29-2.23, P < 0.001 for GG vs GC). However, no significant association was observed under the allelic model (OR = 1.37, 95%CI = 0.99-1.89, P = 0.060 for G vs C), the dominant model (OR = 1.25, 95%CI = 0.92-1.71, P = 0.152 for GG + GC vs CC), and the homozygote comparison model (OR = 1.62, 95%CI = 0.79-3.32, P = 0.186 for GG vs CC). We conclude that the IL-6 -174G/C polymorphism contributes to psoriasis risk. However, further studies should be performed to validate our results.

Abstract
Prostate cancer often manifests as morphologically distinct tumour foci and is frequently found adjacent to presumed precursor lesions such as high-grade prostatic intraepithelial neoplasia (HGPIN). While there is some evidence to suggest that these lesions can be related and exist on a pathological and morphological continuum, the precise clonal and temporal relationships between precursor lesions and invasive cancers within individual tumours remain undefined. Here, we used molecular genetic, cytogenetic, and histological analyses to delineate clonal, temporal, and spatial relationships between HGPIN and cancer lesions with distinct morphological and molecular features. First, while confirming the previous finding that a substantial fraction of HGPIN lesions associated with ERG-positive cancers share rearrangements and overexpression of ERG, we found that a significant subset of such HGPIN glands exhibit only partial positivity for ERG. This suggests that such ERG-positive HGPIN cells either rapidly invade to form adenocarcinoma or represent cancer cells that have partially invaded the ductal and acinar space in a retrograde manner. To clarify these possibilities, we used ERG expression status and TMPRSS2-ERG genomic breakpoints as markers of clonality, and PTEN deletion status to track temporal evolution of clonally related lesions. We confirmed that morphologically distinct HGPIN and nearby invasive cancer lesions are clonally related. Further, we found that a significant fraction of ERG-positive, PTEN-negative HGPIN and intraductal carcinoma (IDC-P) lesions are most likely clonally derived from adjacent PTEN-negative adenocarcinomas, indicating that such PTEN-negative HGPIN and IDC-P lesions arise from, rather than give rise to, the nearby invasive adenocarcinoma. These data suggest that invasive adenocarcinoma can morphologically mimic HGPIN through retrograde colonization of benign glands with cancer cells. Similar clonal relationships were also seen for intraductal carcinoma adjacent to invasive adenocarcinoma. These findings represent a potentially undervalued indicator of pre-existing invasive prostate cancer and have significant implications for prostate cancer diagnosis and risk stratification.
