Objective To study the effects of Aralia chinesis on the proliferation and viability of fibroblasts and on the production of the hyaluronic acid(HA)in the cultured supernatant,and to explore its anti-hepatofibrosis mechanism.Methods NIH3T3 fibroblasts,which were cultured in vitro by routine method and were used as the substitutive model of hepatic stellate cells(HSC),were cultured with the rats serum containing Aralia chinese.The effects of Aralia chinesis serum on the cell proliferation was measured by methabenzthiazuron(MTT)assay and the HA content in cultured supernatant was detected by radioimmunoassay.Results Aralia chinesis serum showed no significant toxicity on NIH3T3 fibroblasts.5 %concentration serum of Aralia chinesis inhibited the cell proliferation and the synthesis of HA significantly(P

Objective To investigate the clinicopathological features,survival,and the impact of postoperative adjuvant radiotherapy on the ovarian function in patients less than or equal to 35 years of age with stage ⅠB-ⅡA cervical cancer.Methods One hundred and eighty-six patients who were admitted to our hospital from 2000 to 2011 were retrospectively analyzed.An equal number of patients older than 35 years of age with cervical cancer within the same period were used as stage-marched controls.The Kaplan-Meier method was used to calculate the survival rates,and the log-rank test was used for pairwise comparison and univariate prognostic analyses.The Cox proportional hazards model was used for multivariate prognostic analyses.Results The patients less than or equal to 35 years of age had a significantly higher incidence of non-squamous carcinoma but significantly lower incidence rates of deep stromal invasion and lymph-vascular space invasion (LVSI) compared with the control group (P =0.000;P =0.008;P =0.000).Though young patients had significantly higher 5-year disease-free survival (DFS) and overall survival (OS) rates than the control group (93.7％ vs.84.5％,P=0.005;96.1％ vs.89.5％,P=0.033),age was not an independent prognostic factor (P =0.202;P =0.950).Among patients less than or equal to 35 years of age,lymph node metastasis and LVSI were independent prognostic factors for DFS (P =0.000;P =0.000),while LVSI and initial tumor size were independent prognostic factors for OS (P =0.000;P =0.000).There was no significant difference in the incidence of normal ovarian function between young patients treated with and without adjuvant radiotherapy after ovarian transposition (63％ vs.73％,P =0.422).Conclusions Patients less than or equal to 35 years of age with stage ⅠB-ⅡA cervical cancer have a better prognosis than the control group.However,age is not an independent prognostic factor.Postoperative adjuvant radiotherapy will not impair the function of transposed ovaries.

Objective To investigate the relationship between the channel design of tandem-andovoid (T&O) applicator and the doses to organs at risk (OARs) and target volume in three-dimensional brachytherapy for advanced cervical carcinoma.Methods The data on 15 patients with advanced cervical carcinoma treated with three-dimensional brachytherapy in our hospital from 2015 to 2016 were collected,and 30 randomly selected high-dose-rate titanium T&O plans were retrospectively studied.CT-guided,conformal brachytherapy plans were generated.To simulate T&O applicator,the tandem applicator was virtually compared with the T&O plans with the target volume and OARs remaining unchanged.The DVH parameters of the rectum,bladder,and sigmoid were compared using the paired t test.Results For T&O plans and tandem applicator plans,the mean D2cc of the rectum was 387.8±96.8 cGy and 340.8±88.1 cGy,respectively;the mean D2cc of the bladder was 443.2± 87.5 cGy and 719.4± 243.0 cGy,respectively;the mean D2cc of the sigmoid was 330.3±88.8 cGy and 383.1±105.6 cGy,respectively.In the T&O plans,the doses to the rectum,bladder,and sigmoid were within the limits (rectum:D2cc ≤ 500 cGy;bladder:D2cc ≤ 550 cGy;sigmoid:D2c ≤ 500 cGy),while D2cc of the bladder and sigmoid was higher or partially higher than the limits.T&O plans showed a significant reduction in bladder D2cc and sigmoid D2cc compared with the tandem applicator plans (all P＜0.05).Conclusions Compared with tandem applicator plans,plans using T&O applicator provide significant sparing of bladder and sigmoid tissues in three-dimensional brachytherapy for cervical carcinoma,but the toxicities require further investigation.

Objective: To study relationship between coronary heart disease (CHD) and dyslipidemia. Methods: A total of 302 CHD patients diagnosed by coronary angiography were enrolled as CHD group, and 218 healthy subjects without cardiovascular and cerebrovascular diseases by health examination were regard as healthy control group. Relative data were collected and levels of blood triglyceride (TG), total cholesterol (TC), high density lipoprotein cholesterol (HDL-C) and low density lipoprotein cholesterol (LDL-C) were measured and compared between two groups. Results: Compared with healthy control group, there were significant increase in levels of blood TC [(4.03±0.97) mmol/L vs. (4.62±1.06) mmol/L] and LDL-C[(2.51±0.86) mmol/L vs. (3.76±1.07) mmol/L] in CHD group, P<0.01 both. Multiple factor Logistic regression analysis indicated that elevated LDL-C level was an independent risk factor for occurrence of CHD (OR=2.608, 95%CI = 1.268-5.366, P=0.009). Conclusions: The results show that levels of TC and LDL-C in patients with coronary heart disease are significantly higher than those of healthy control group. Elevated LDL level may be an independent risk factor for occurrence of coronary heart disease.

Objective To investigate the risk factors and etiology in young adults with ischemic stroke.Methods From June 2014 to June 2017,consecutive patients with first-ever ischemic stroke aged from 18 to 45 years and admitted to the Department of Neurology,the Third People's Hospital of Chengdu were collected retrospectively.The demographic data,vascular risk factors,National Institutes of Health Stroke Scale score,location of infarction,and etiological subtypes were documented.They were divided into either a male group or a female group according to the gender,and they were divided into 2 age groups of 18-35 years and 36-45 years.Results A total of 103 young adults with ischemic stroke were enrolled during the study.Among them,the proportion of men was higher than that of women (73.8％ vs.26.2％).The most common 5 risk factors were smoking,abnormal lipid metabolism,drinking alcohol,hypertension,and large atherosclerosis,respectively.The proportions of abnormal glucose metabolism (37.2％ vs.11.8％),hypertension (46.5％ vs.11.8％),and large artery atherosclerosis (37.2％ vs.11.8％) in the age group of 36-45 years were significantly higher than those in the age group of 18-35 years (all P＜0.05).The proportions of smoking (67.1％ vs.14.8％) and drinking alcohol (51.3％ vs.18.5％) in the male group were significantly higher than those in the female group (all P＜ 0.05).In the etiological aspect,the proportion of cryptogenic stroke in the age group of 18-35 years was significantly higher than that in the age group of 36-45 years (47.1％ vs.15.1％;P=0.006),while the proportion of the large artery atherosclerotic stroke was significantly lower than that in the age group of 36-45 years (11.8％vs.41.9％;P =0.019).There were no significant differences in the etiological subtypes between different sex groups.Conclusion The distribution of risk factors and etiological subtypes in young patients with ischemic stroke have some differences in different gender and age groups.Some common modifiable risk factors (such as smoking,drinking,abnormal lipid metabolism,etc.) still account for a higher proportion in young adults with ischemic stroke.

Objective: To identify the risk factors of perioperative complications after radical gastrectomy for gastric cancer. Methods: A retrospective case-control study was performed. Case inclusion criteria: (1) patients undergoing radical gastrectomy (D2); (2) primary gastric cancer without distant organ metastasis confirmed by postoperative pathology; (3) no neoadjuvant chemotherapy before surgery. Patients with peritoneal tumor dissemination found during operation, undergoing palliative operation due to distant metastasis, and undergoing combined organ resection and those without complete clinicopathological data were excluded. According to the above criteria, 426 patients with gastric cancer at our department from January 2015 to June 2017 were included in this study. Of 426 patients, 285 were male and 141 were female with a mean age of (55.4±9.7) years. According to the "Japan Clinical Cancer Research Group (JCOG) classification criteria for postoperative complications of gastric cancer", patients with grade II and higher complications were classified as complication group, and patients with no complication or grade I complication were classified as non-complication group. Baseline data were compared between two groups. Associations of perioperative complication with gender, age, body mass index, preoperative routine laboratory test, American Society of Anesthesiologists (ASA) classification, activities of daily living (ADL) assessment, past medical history as well as preoperative conditions (hypertension and/or diabetes), surgical resection procedure, incision type, operation time, intraoperative blood loss/body mass ratio were examined. Univariate analysis was performed using χ² test and the Wilcoxon rank sum test to screen the statistically significant variables associated with perioperative complications. The significant variables were included in multivariate logistic regression analysis to identify risk factors of perioperative complication. Results: Grade II or higher complications after surgery were developed in 97 patients (22.8%), which included anastomotic leakage in 18 cases (4.2%), postoperative bleeding in 9 cases (2.1%), abdominal abscess in 5 cases (1.2%), intestinal obstruction in 5 cases (1.2%), pancreatic leakage in 1 case (0.2%), and other adverse events in 59 cases (13.8%). Univariate analysis suggested that the gender, age, ADL, incision type, intraoperative blood loss/body mass ratio, and operation time were associated with perioperative complication (all P<0.05). Multivariate analysis revealed that elder age (OR=1.033, 95% CI:1.013-1.053, P=0.013), incision type of laparotomy (OR=2.091, 95% CI:1.247-3.508, P=0.004), longer operation time (OR=1.004, 95% CI:1.001-1.007, P=0.001) and higher ratio of intraoperative blood loss/body mass (OR=1.100, 95% CI: 1.039-1.163, P=0.031) were risk factors for postoperative complications. Conclusion Attention should be paid to those cases with elder age, laparotomy incision, longer operation time and higher ratio of intraoperative blood loss/body mass, and perioperative management after gastrectomy should be improved.

Objective:To evaluate the objective response rate (ORR) of induction chemoimmunotherapy with camrelizumab plus TPF (docetaxel, cisplatin, and capecitabine) for locally advanced hypopharyngeal squamous cell carcinoma (LA HSCC) and potential predictive factors for ORR.Methods:A single-center, prospective, phase 2 and single-arm trial was conducted for evaluating antitumor activity of camrelizumab+TPF(docetaxel+cisplatin+capecitabine) for LA HSCC between May 21, 2021 and April 15, 2023, patients admitted to the Eye & ENT Hospital affiliated with Fudan University. The primary endpoint was ORR, and enrolled patients with LA HSCC at T3-4N0-3M0 received induction chemoimmunotherapy for three cycles: camrelizumab 200 mg day 1, docetaxel 75 mg/m 2 day 1, cisplatin 25 mg/m 2 days 1-3, and capecitabine 800 mg/m 2 days 1-14. Patients were assigned to radioimmunotherapy when they had complete response or partial response (PR)>70% (Group A), or assigned to surgery plus adjuvant radiotherapy/chemoradiotherapy when they had PR≤70% (Group B), and the responses were defined by using tumor volume evaluation system. Tumor diameter was also used to assess the treatment responses by Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1. Use SPSS 23.0 software was used to analyze the data. Results:A total of 51 patients were enrolled who underwent the induced chemoimmunotherapy for three cycles, and all were males, aged 35-69 years old. After three cycles of induction immunochemotherapy, 42 (82.4%) patients existed in Group A (complete response or PR>70%) and 9 patients (17.6%) in Group B (PR≤70%), the ORR was 82.4%. The primary endpoint achieved expected main research objectives. Compared to the patients of Group A, the patients of Group B showed the higher T stage and the larger volume of primary tumor before induced immunochemotherapy, and also had the less regression of tumor volume after induced immunochemotherapy (all P<0.05). The optimal cutoff value of pre-treatment tumor volume for predicting ORR was 39 cm 3. The T stage ( OR=12.71, 95% CI: 1.4-112.5, P=0.022) and the volume ( OR=7.1, 95% CI: 1.4-36.8, P=0.018) of primary tumor were the two main factors affecting ORR rate of induction chemoimmunotherapy. Conclusion:The induction chemoimmunotherapy with camrelizumab plus TPF shows an encouraging antitumor efficacy in LA HSCC.
