Objective:To investigate the clinical and genetic characteristics and predictive role of the severe liver disease phenotype in patients with hepatolenticular degeneration (HLD).Methods:Inpatients with HLD confirmed at Xinhua Hospital affiliated with Shanghai Jiao Tong University School of Medicine from January 1989 to December 2022 were selected as the research subjects. Clinical classification was performed according to the affected organs. Patients with liver disease phenotypes were classified into the liver disease group and further divided into the severe liver disease group and the ordinary liver disease group. The clinical characteristics and genetic variations were compared in each group of patients. The predictive indicators of patients with severe liver disease were analyzed by multiple regression. Statistical analysis was performed using the t-test, Mann-Whitney U test, or χ2 test according to different data. Results:Of the 159 HLD cases, 142 were in the liver disease group (34 in the severe liver disease group and 108 in the ordinary liver disease group), and 17 were in the encephalopathy group. The median age of onset was statistically significantly different between the liver disease group and the encephalopathy group [12.6 (7.0, 13.3) years versus 16.9 (11.0, 21.5) years, P<0.01]. 156 ATP7B gene mutation sites were found in 83 cases with genetic testing results, of which 54 cases carried the p.Arg778Leu gene mutation (allele frequency 46.2%). Compared with patients with other types of gene mutations ( n=65), patients with homozygous p.Arg778Leu mutations ( n=18) had lower blood ceruloplasmin and albumin levels, a higher prognostic index, Child-Pugh score, an international normalized ratio, and prothrombin time ( P<0.05). Hemolytic anemia, corneal K-F ring, homozygous p.Arg778Leu mutation, and multiple laboratory indexes in the severe liver disease group were statistically significantly different from those in the ordinary liver disease group ( P<0.05). Multivariate logistic regression analysis showed that the predictive factors for severe liver disease were homozygous p.Arg778Leu mutation, total bilirubin, and bile acids ( ORs=16.512, 1.022, 1.021, 95% CI: 1.204-226.425, 1.005-1.039, and 1.006-1.037, respectively, P<0.05). The drawn ROC curve demonstrated a cutoff value of 0.215 3, an AUC of 0.953 2, and sensitivity and specificity of 90.91% and 92.42%, respectively. Conclusion:Liver disease phenotypes are common in HLD patients and have an early onset. Total bilirubin, bile acids, and the homozygous p.Arg778Leu mutation of ATP7B is related to the severity of liver disease in HLD patients, which aids in predicting the occurrence and risk of severe liver disease.

Objective: To investigate the association of parental knowledge and skills in myopia prevention and control with healthy eye behavior in primary school children, so as to provide a basis for accurate family education. Methods: A total of 4 979 students in grades 1-5 from eight elementary schools in Pudong New Area were sampled between October and December in 2022 by using a stratified cluster sampling method. A self administered questionnaire was used to assess healthy eye behavior in primary school children and parental knowledge and skills in myopia prevention and control. The Chi squared test, independent samples t-test and Logistic regression were used to analyse the association between parental knowledge and skills in myopia prevention and control and healthy eye behaviour in primary school children. Results: Parents of primary school children with a high level of knowledge and skills in myopia prevention and control were 50.97% and 56.36%, respectively. The knowlegde entry scores for parents of lower and middle elementary school students were higher than those of parents of upper primary students with respect to their understanding, on the main causes of myopia in their children, the correct knowledge of myopia prevention and control, the role of family members in helping each other to manage and treat myopia in their children and the parents responsibility to teach their children to use their eyes correctly and scientifically (3.05±1.21, 2.97±1.20; 5.92±0.68, 5.83±0.86; 4.46±0.88, 4.40±0.93; 3.88±1.04, 3.72±1.07); all differences were statistically significant (t=2.04, 3.39, 2.00, 4.87, P<0.05). The differences in the scores of parents of primary school children in different grades for all items were statistically significant (t=2.93-7.31, P<0.05) in the skill entries. Parental knowledge levels were poor for items of full scores that assessed the following: knowing the main causes of their childrens myopia, awareness of the correct knowledge of myopia prevention and control measures, awareness of Comprehensive Prevention and Control Strategy for Children and Adolescents with Myopia, and concerning that their childrens future education and employment will be affected by myopia, understanding the responsibility of parents for guiding children to use their eyes scientifically and correctly, with 12.71%, 22.90%, 19.30%, 21.83% and 22.47% respectively. Parental skills were poor for items of full scores that assessed the following:reminding their children to rest their eyes when doing homework, reading or writing, deliberately avoiding mobile phone use when spending time with their children, the number of times which taking children to the hospital for refractive screening in the past year, and giving their children extra learning tasks, with 33.26%, 15.12%, 9.00% and 5.36% respectively. Compared to parental knowledge in myopia prevention and control, parental skills had a more pronounced effect on the four dimensions of healthy eye behavior (reading and writing, screen time, outdoor activities, and sleep duration) among students in different grades (OR=1.41-3.37, P<0.05). Conclusions Parental knowledge and skills in myopia prevention and control are still insafficient, associated with healthy eye behavior in primary school children. There is a need to strengthen accurate health education for parents on the prevention and control of myopia, to cultivate healthy eye behaviour among primary school students and reduce the incidence of myopia among them.

expression level of FGF2 protein in the HA-VSMCs in 0.100 mg·L-1 Xiaoban Tongmai Formula group was decreased(P＜0.01).Conclusion:Xiaoban Tongmai Formula has anti-inflammatory effect,inhibitory effect on the proliferation of HA-VSMCs,and anti-AS effect,and its mechanism may be related to the inactivation of NF-κB/FGF2 pathway.

Objective: To investigate the factors affecting cataract among the elderly, so as to provide insights into cataract control. Methods: Based on the major public health monitoring project of Zhejiang Province, residents at ages of 60 years and older were selected from 7 districts (counties) using a multi-stage stratified cluster random sampling method, and were followed up every other year from 2014 to 2020. Demographics, lifestyle, dietary habits and cataract incidence were collected, and factors affecting the incidence of cataract were identified using a multivariable Cox proportional hazard regression model. Results: Totally 9 642 residents were investigated, with a mean age of (68.89±7.39) years, and including 4 635 males (48.07%). There were 828 incident cataract cases, with an incidence rate of 20.946/1 000 person-years. Multivariable Cox proportional hazard regression analysis showed that women (HR=1.695, 95%CI: 1.377-2.088), age of 65 years and older (HR=1.707-5.044, 95%CI: 1.400-7.327), overweight/obesity (HR=1.313, 95%CI: 1.131-1.524), educational level (primary school, HR=1.642, 95%CI: 1.400, 1.926; junior high school, HR=1.553, 95%CI: 1.148-2.102), annual family income (10 000 to 50 000 Yuan, HR=1.353, 95%CI: 1.155-1.585; 50 000 to 100 000 Yuan, HR=0.663, 95%CI: 0.500-0.881; 100 000 to 150 000 Yuan, HR=0.340, 95%CI: 0.204-0.565), smoking (HR=0.649, 95%CI: 0.494-0.853), frequency of vegetable intake of >3 days/week (HR=0.693, 95%CI: 0.527-0.912), frequency of fruit intake of >3 days/ week (HR=0.833, 95%CI: 0.694-0.899), frequency of egg intake of >3 days/week (HR=0.579, 95%CI: 0.450-0.745), frequency of soy products intake of >3 days/week (HR=0.706, 95%CI: 0.588-0.849), frequency of dairy products intake of >3 days/week (HR=1.510, 95%CI: 1.199-1.901) and frequency of nut intake of >3 days/week (HR=1.733, 95%CI: 1.162-2.586) were statistically associated with the development of cataract among the elderly. Conclusion Gender, age, body mass index, educational level, income, smoking, and frequency of vegetables, fruits, eggs, soy products, dairy products and nuts intake are associated with the development of cataracts.

Objective:To explore the value of using the mean gamma index (GI) in targer area receiving 50% prescribed dose as reference in VMAT planned dose verification through model-based dose calculation and measurement-based dose reconstruction.Methods:Based on Compass dose verificantion system, the VMAT plans for 70 patients were validated using two method. The mean GI and passing rate in target area receiving 50% of prescribed dose area for each validation plan were obtained to evaluate its application value in dose validation. First, plan information obtained by TPS calculation was input into the Compass system for performing independent dose calculation based on the accelerator data model, and obtain a three-dimensional dose based on the independent model calculation. The planned fluence measured for each patient′s treatment plan on the accelerator was reconstructed through the Compass system to obtain a three-dimensional dose based on measurement reconstruction. The three-dimensional dose obtained by the two method were compared with the three-dimensional dose calculated by TPS.Results:Combined with the gamma criteria of 3%/3 mm in the error setting condition of GI analysis, the mean GI in the area receiving 50% of prescribed dose was evaluated. GI≤0.4 was classified as PASS, 0.4 < GI ≤ 0.6 as being clinically acceptable, and GI > 0.6 as FAIL. The VMAT planned dose verification for 70 patients showed that the model-based independent calculation was in a better agreement with the TPS calculation. The GI values were all < 0.6: GI≤0.4 for 67 patients and 0.4 90% for 88 patients and < 90% for other 2, all meeting the requirements of clinical dose verification. The model-based independent dose verification is better than the measurement-based reconstructed dose verificantion, and the difference is statistically significant ( t=15.20, 10.71, P < 0.05). Conclusions:The mean GI in target area receiving 50% of prescribed dose can be used as a reference to judge the operatability of clinical plan in clinical dose verification. The mean GI value, in combination with the comprehensive result of gamma passing rate, is more convincing to evaluate dose verification. A combination of model-based dose verification, despite time-saving and labor-saving, and the measurement-based dose verification could become a reliable dose verification method for clinical application.

Objective:To analyze long-term outcomes of inoperable non-metastatic pancreatic cancer patients treated with definitive radiotherapy-based comprehensive treatment.Methods:Clinical data of 168 patients with medically unfit, refusal to surgery or inoperable non-metastatic pancreatic cancer treated with radiotherapy-based comprehensive treatment in PLA General Hospital between January 2016 and December 2020 were retrospectively analyzed. Survival outcomes,prognostic factors and patterns of treatment failure were analyzed in the radiotherapy ( n=95) and combined chemoradiotherapy ( n=73) groups. The survival analysis was conducted by Kaplan-Meier method. The survival curve was compared by log-rank test. Independent prognostic factors were identified by Cox proportional harzard model. Results:With a median follow-up of 20.2 months in the entire group, the median overall survival (OS) and median progression-free survival (PFS) were 18.0 and 12.3 months. The corresponding median OS and median PFS after receiving radiotherapy were 14.3 and 7.7 months. The 1-, 2-and 3-year OS rates were 72.1%, 36.6% and 21.5%, and the 1- and 2-year local control rates were 82.6% and 64.3%, respectively. The median OS for stage Ⅰ, stage Ⅱ and stage III were 27.1, 18.0 and 17.0 months, respectively. There was no significant difference in the median OS of patients with localized disease (stage Ⅰ-Ⅱ) between the radiotherapy and combined chemoradiotherapy groups (21.1 vs. 20.4 months, P=0.470). In patients with locally advanced disease (stage Ⅲ), combined chemoradiotherapy group showed better median OS compared with radiotherapy group (19.2 vs. 13.8 months, P=0.004). Clinical stage, CA19-9 before radiotherapy, comprehensive treatment and biological effective dose (BED 10) were identified as the independent prognostic factors for OS ( P=0.032, 0.011, 0.003 and 0.014). The cumulative 1- and 2-year actuarial rates of treatment failure, local-regional recurrence and distant metastasis were 48% and 74.4%, 15.0% and 27.4%, 23.6% and 33.1%, respectively. Liver metastasis (16.1%, 27/168) and local recurrence (11.9%, 20/168) were the primary patterns of treatment failure. Conclusions:Definitive radiotherapy-based comprehensive treatment effectively prolongs long-term survival in patients with inoperable non-metastatic pancreatic cancer. Definitive radiotherapy can be an alternative treatment option with curative intent for patients with localized pancreatic cancer who are medically unfit or refuse to undergo surgery. The combination of radiotherapy and chemotherapy remains an effective treatment choice for locally advanced unresectable pancreatic cancer.

Obesity is a global public health problem that imposes a heavy economic burden on society. The current main strategies for treating obesity include lifestyle interventions, pharmacological treatments, endoscopic treatments and metabolic surgery. With the development of medical technology, weight reduction by intragastric occupancy devices represented by intragastric balloons and intragastric capsules are gradually emerging. Intragastric balloons are used to reduce weight by occupying the volume of the stomach with balloons filled with different volumes of gas or liquid, among which ReShape, Orbera, Obalon, Elipse and Spatz balloons are gradually used in patients with mild to moderate obesity due to their non-invasive, high safety and reusable advantages. Intragastric capsules are recommended in overweight and obese patients for weight loss through hydrogels with transient superabsorbent swelling properties and completely noninvasive. Both approaches achieve weight loss by limiting gastric volume, increasing satiety and reducing food intake. Despite the presence of adverse gastrointestinal events associated with nausea, vomiting, and abdominal distention, they offer new ideas for the non-invasive clinical treatment of obesity.

Objective:To evaluate the relationship between the mechanism of propofol inhibiting carotid sinus baroreflex (CSR) and GluR2 subunit-containing AMPA receptors in the nucleus ambiguus of rats with type 2 diabetes mellitus (T2DM).Methods:SPF healthy male Sprague-Dawley rats, aged 3 weeks, were selected and fed a high glucose and high fat diet for 6 weeks, and then streptozotocin 30 mg/kg was intraperitoneally injected to prepare a T2DM model of rats. Twenty-four T2DM rats were divided into 4 groups ( n=6 each) using a random number table method: diabetes mellitus-normal saline group (DN group), diabetes mellitus-propofol group (DP group), AMPA receptor agonist-normal saline group (AN group), and AMPA receptor agonist-propofol group (AP group). Another 12 normal rats were selected and divided into 2 groups ( n=6 each) using a random number table method: normal-normal saline group (NN group) and normal-propofol group (NP group). AMPA receptor agonist mibamitor 1 nmol/L (50 nl) was injected into the nucleus ambiguus using a micropipette at 30 min before perfusion of isolated carotid sinus in AN and AP groups. Propofol 45 mg·kg -11·h -1 was infused for 2 h via the femoral vein in NP group, DP group and AP group, and the equal volume of normal saline was given instead in the other groups. A model for perfusing isolated carotid sinus was developed at 20 min after infusion of propofol or normal saline, the intracarotid sinus pressure (ISP)-mean arterial blood pressure (MAP) curve was drawn, and CSR parameters such as maximum slope (PS), threshold pressure (TP), saturation pressure (SP), equilibrium pressure (EP), maximum decrease in MAP reflexivity (RD), and carotid sinus baroreceptor operating range (OR) were recorded. Brain tissues were taken at the end of perfusion, and the expression of GluR2 subunit in the nucleus ambiguus was detected by Western blot and immunofluorescence. Results:Compared with the corresponding normal saline groups (NN group, DN group, AN group), PS and RD were significantly decreased, TP, SP and OR were increased ( P<0.05), and the ISP-MAP curve was shifted upward in propofol groups (NP group, DP group, AP group), the expression of GluR2 subunit in the nucleus ambiguus was down-regulated in NP and DP groups ( P<0.05), and no significant change was found in the expression of GluR2 subunit in the nucleus ambiguus in AP group ( P>0.05). Compared with NP group, PS and RD were significantly decreased, TP, SP and OR were increased ( P<0.05), the ISP-MAP curve was shifted upward, and the expression of GluR2 subunit in the nucleus ambiguus was down-regulated in DP group ( P<0.05). Compared with DP group, PS and RD were significantly increased, TP, SP and OR were decreased ( P<0.05), the ISP-MAP curve was shifted downward, and the expression of GluR2 subunit in the nucleus ambiguus was up-regulated in AP group ( P<0.05). Conclusions:The mechanism by which propofol inhibits CSR may be related to down-regulation of the expression of GluR2 subunits-containing AMPA receptors in the nucleus ambiguus of rats with T2DM.

Esophageal cancer is a type of upper gastrointestinal malignant tumor with a high degree of malignancy， strong invasion ability， and poor prognosis， which belongs to the category of "dysphagia" in traditional Chinese medicine （TCM）. In addition to tumor resistance， Chinese herbal prescription plays a role in sensitization. In light of information in literature， the syndrome elements of esophageal cancer include Qi stagnation， phlegm， Qi deficiency， blood stasis， and Yin deficiency. After clinical differentiation， the syndromes of esophageal cancer are divided into phlegm and Qi obstruction， Qi and Yin deficiency， fluid deficiency and heat accumulation， Qi deficiency and phlegm dampness， combined phlegm and heat， combined phlegm and stasis， combined heat toxin and stasis， healthy Qi deficiency and toxin accumulation， et al. Dabanxiatang， Qigesan， Xuanfu Daizhetang， Liujunzitang， Shashen Maidongtang， and Tongyoutang are the common clinical prescriptions， where Qigesan， Liu Junzitang， and Tongyoutang have been proved by in vitro and in vivo experiments to exert anti-esophageal cancer effect by directly inhibiting tumor cell proliferation， promoting apoptosis， affecting tumor microenvironment， regulating cell energy metabolism， and inhibiting angiogenesis. In addition， an increasing number of studies have been conducted on anti-esophageal cancer effect of Chinese herbal prescription by targeting non-coding single-stranded microRNA. The specific mechanisms of Da Banxiatang， Shenzhe Peiqitang， Xiao Xianxiongtang， Renshen Banxiatang， and Liushenwan have been scarcely reported despite good clinical efficacy. Wuzhuyu Tang and Tongguansan recorded in ancient books have been rarely applied in modern times. Therefore， the present study reviewed the special drugs and prescriptions mentioned in ancient TCM classics， the commonly used Chinese herbal prescriptions in modern clinical practice， and experimental research progress， to promote treatment methods of Chinese herbal prescriptions against esophageal cancer.

Objective:Analysis of the antibiotic resistance profiles and molecular typing of Salmonella typhimurium ( S. typhimurium) isolated in Wuxi city from 2011 to 2018. Methods:A total of 109 S. typhimurium isolates were detected from different types monitoring samples in Wuxi city from 2011 to 2018. Microbroth dilution method was used to test antimicrobial susceptibility of S. typhimurium for 17 antimicrobial agents. Pulsed field gel electrophoresis (PFGE) was used to conduct molecular typing. Statistical analysis was carried out using Chi-square test. Results:Tetracycline-resistance and ampicillin-resistance were most frequency in 109 S. typhimurium isolates, 69.72% (76/109) and 68.81% (75/109), respectively. For compound sulfamethoxazole, chloramphenicol, ciprofloxacin, ampicillin/sulbactam, azithromycin, nitrofurantoin, cefotaxime and aztreonam, the resistance rates were 23.85%(26/109), 22.02%(24/109), 11.93%(13/109), 4.59%(5/109), 3.67%(4/109), 3.67%(4/109), 0.92%(1/109), 0.92%(1/109), respectively. All isolates were susceptible to amikacin, ertapenem, imipenem, meropenem, ceftazidime and ceftazidime-avibactam. Azithromycin-resistance isolates were decreasing year by year gradually. The aztreonam and cefotaxime-resistant isolates were found since 2018, while chloramphenicol and compound sulfa-resistant isolates showed upward trend simultaneously. Conclusions:S. typhimurium in Wuxi city exhibited highly resistant to tetracycline and ampicillin. The significant variability existed between genotype and phenotype of S. typhimurium.
