To explore the effects of nutritional risks on clinical outcomes [length of stay (LOS),hospitalization expense & mortality] in chronic kidney disease (CKD) patients.A total of 127 CKD patients completed the screening of nutritional risks by Nutritional Risk Screening 2002 (NRS-2002) within 24-48 hours of admission.The data of nutritional supports within 2 weeks of admission,LOS,hospitalization expense and mortality were collected.① Among them,the prevalence of nutritional risks was 18.1％.And the values were 8.2％,9.4％ and 44.1％ in early,middle and advanced CKD groups respectively; ② LOS and hospitalization expense in nutritional risk group were significantly more than the non-nutritional risk group (12.5 d vs.5.2 d,P =0.00 ; 11 806 vs.5311 yuan,P =0.00).There was a positive correlation between NRS score and LOS or hospitalization expense; ③ The nutritional support rate of nutritional risk group was only 17.4％.The progression of CKD increased the nutritional risks leading to greater LOS and hospitalization expense.We should pay more attention to the nutritional risk screening and nutritional intervention in moderate-advanced CKD patients.

Objective To determine the optimal injection dose of ozone for the treatment of lumbar intervertebral disc protrusion.Methods A total of 240 patients with lumbar intervertebral disc protrusion were randomly and equally divided into four groups,with 60 patients in each group.Under CT guidance intervertebral injection of ozone was performed.The injection dose of ozone(50 ug/ml)used for patients in group A,B,C and D was 10 ml,20 ml,30 ml and 40 ml respectively.Immediately after the procedure CT scanning was made to check the result. A follow-up lasting 6-12 months was carried out.Clinical observation,including the ablation degree of the nucleus puiposus,the therapeutic results and the adverse reactions,was conducted.The results were statistically analyzed and compared among the four groups.Results A significant difference in the therapeutic effect existed between group A(10 ml)and other three groups(P＜0.05),while no significant difference in the therapeutic effect existed among group B(20 ml),group C(30 ml)and group D(40 ml),with P＞0.05.The occurrence of complications was increasing with the injection dose used.Conclusion The optimal injection dose of ozone for the treatment of lumbar intervertebral disc protrusion is 20 ml.

The study is designed to investigate the progress in cardiac auscultation proficiency of residents after training program.Thirty eight residents were selected to test their ability of cardiac auscultation.There were 13 cardiac events(or murmurs)in 15 patients,and the auscultation proficiency was expressed as the percentage of recognizing cardiac events accurately.The results showed that the highest auscultation proficiency was whole systolic and diastolic murmurs(up to 79 percent and 61 percent respectively)before training.The percentage of recognizing continuous murmurs,click,mitral stenosis and regurgitation,aortic stenosis increased significantly after training program(P＜0.05).

Depression is a common complication after stroke.It is often associated with disability,cognitive impairment,and increased mortality.This article reviews the epidemiology,risk factors,predictive factors,and pathophysiology mechanisms of post-stroke depression.

The etiology of deep vein thrombosis (DVT) is still not elucidated nowadays. Based on the accordance between DVT incidence and the anemophilous pollen concentration in the air, we proposed the hypothesis that allergic reaction induced by anemophilous pollen may cause "idiopathic" DVT, and proinflammatory factors may play an important role in the thrombosis process.

Malaysia is a multi-ethnic and multi-cultural constitutional monarchy and federal system located in Southeast Asia. The top three diseases that cause deaths are ischemic heart disease, lower respiratory tract infections and stroke. Lower respiratory tract infections, colorectal cancer and Alzheimer’s disease have been the fastest growing diseases in recent years. The health insurance system complements public and private health care system. Traditional medicine in Malaysia includes Malaysian Medicine, Traditional Chinese Medicine (TCM), Indian Medicine, Islamic Medicine and homeopathy. Although TCM, such as acupuncture, has not been covered by health insurance, it is widely used under the impetus of the local Chinese people. At present, in Malaysia, the TCM public acceptance and education need promotion, and scientific researches need to be improved. It is hoped that in the future, the development of TCM in Malaysia will be better developed and disseminated by promoting TCM relevant legislation, increasing public awareness, focusing on education and training, and carrying out international scientific research cooperation.

OBJECTIVE: To investigate the clinical and pathological characteristics of sinonasal neoplasms. METHOD: A cohort of 333 patients with sinonasal neoplasm, which were confirmed by surgical pathology, were enrolled in this study. The clinicopathological characteristics, in terms of age, sex, location, and disease constituent ratio were retrospectively reviewed. RESULT: (1) In this series of patients, there were 200 males and 133 females, aged from 2 to 84 years, with a median of 54 years. The benign to malignant ratio was 1.1:1. As for their origination, 144 tumors arose from the nasal cavity, while, 191 tumors derived from sinus, including 90 from maxillary sinus, 31 from frontal sinus, 46 from ethmoid sinus, and 24 from sphenoidal sinus. (2) Disease constituent ratio decreased in order of epithelial tissue, soft tissue, lymphohematopoietic tissue, bone and cartilaginous tissue, ectopic intracranial tumors. The five most frequent malignant tumors were squamous carcinoma, lymphoma, adenoid cystic carcinoma, malignant melanoma and esthesioneuroblastoma, while, benign tumors ranked in the top five were papilloma, fibroma, osteoma, angioma and ectopic intracranial tumors,respectively. (3) Of 200 cases arising from epithelium, 118 were benign, 82 were malignant, and the benign to malignant ratio was 1.4:1. Of 68 cases from soft tissue, 37 were benign and 31 were malignant tumors (ratio, 1.2:1). Among the 22 cases from bone and cartilaginous tissue, 17 were benign and 5 were malignant (ratio, 3.4:1). With respect to the 29 cases from lymphohematopoietic tissue, the majority of tumors were malignant (28 cases), with only one benign case. In addition, ectopic intracranial tumors were also observed. Besides the above all, 12 cases of other types were found in this work. CONCLUSION Neoplasms from different parts of nasal cavity and paranasal sinus have specific clinical characteristics. The pathological types of these tumors may be highly diverged. The diagnosis and differential diagnosis depend mainly on pathological examination. Comprehensive treatment, which employs surgery in combination with other modalities, is the main strategy for these tumors.

Objective To evaluate the effect and mechanism of rivaroxaban, an inhibitor of coagulation factor Ⅹa (FⅩa), on endotoxin-induced injury to human umbilical vein endothelial cells (HUVEC). Methods When cultured HUVEC grow to 80% fusion, they were divided into four groups according to the random number method: blank control group (DMEM medium), lipopolysaccharide (LPS) group (cells were challenged by 100 μg/L LPS for 16 hours), FⅩa+LPS group (cells were challenged by LPS for 16 hours after they were cultured with 100 nmol/L FⅩa for 24 hours), and FⅩa+RIV+LPS group (cells were challenged by LPS for 16 hours after they were cultured with 100 nmol/L FXa and 1 μmol/L rivaroxaban for 24 hours). After each group of cells were challenged with LPS, the cell activity was detected by the cell proliferation and toxicity kit (CCK-8); the cell migration ability was detected by cell scratch experiments;the abilities of cells migration were measured by scratch-wound-healing assay; the apoptosis of cells were evaluated using flow cytometry; the endothelial barrier of cells was assessed by Transwell and Evans blue; the levels of tumor necrosis factor-α(TNF-α), interleukin (IL-1β, IL-6) were detected by the enzyme linked immunosorbent assay (ELISA); the expressions of nuclear factor-κB (NF-κB) and mitogen activated protein kinase (MAPK) signaling pathway were detected by Western Blot. Results Compared with blank control group, the cell viability in LPS group was significantly decreased, and the migration ability, number of apoptotic cells, and barrier permeability of endothelial cells was significantly increased, the levels of TNF-α, IL-1β and IL-6 were significantly increased, and the expressions of phosphorylation of c-Jun N-terminal kinase (p-JNK), phosphorylation of p38MAPK (p-p38MAPK), phosphorylation of transforming growth factor kinase 1 (p-TAK1) and phosphorylation of NF-κBp65 (p-NF-κBp65) were significantly increased. It indicated that LPS could stimulate the inflammatory response of vascular endothelial cells, and had a significant impact on cell activity, apoptosis and function. There was no significant difference in above indexes between FⅩa+LPS group and LPS group, except for the level of IL-6 being higher in FⅩa+LPS group. Compared with FⅩa+LPS group, in FⅩa+RIV+LPS group, the cell activity was significantly increased (A value: 0.42±0.02 vs. 0.33±0.02), and migration ability was significantly decreased (folds: 1.78±0.17 vs. 2.24±0.20), the number of apoptotic cells was significantly decreased [(11.30±0.70)% vs. (21.03±0.19)%], and permeability of monolayers endothelial cells was significantly decreased [(149±12)% vs. (253±15)%], the levels of inflammatory cytokines were significantly decreased [IL-1β(ng/L): 163.2±20.7 vs. 477.8±20.2, IL-6 (ng/L): 69.3±0.5 vs. 238.0±24.1, TNF-α(ng/L): 117.0±13.1 vs. 196.2±4.5], the expressions of p-TAK1 and p-NF-κBp65 were significantly decreased (p-TAK1/TAK1: 0.74±0.09 vs. 1.85±0.15, p-NF-κBp65/NF-κBp65: 1.15±0.17 vs. 2.36±0.20), with statistically significant differences (all P <0.05). There was no significant difference in the p-JNK, p-p38MAPK expressions between FⅩa+RIV+LPS group and FⅩa+LPS group (p-JNK/JNK: 1.64±0.12 vs. 1.65±0.15, p-p38MAPK/p38MAPK: 2.31±0.32 vs. 2.35±0.20, both P > 0.05). Conclusion Rivaroxaban can effectively relieve the inflammatory response of HUVEC stimulated by LPS, which may be related to the inhibition of NF-κB signaling pathway activation rather than MAPK signaling pathway.

Objective:Synchronous mucinous metaplasia and neoplasia of the female genital tract (SMMN-FGT) occurring at multiple sites during the same period of time is extremely rare, and the aim of this study was to investigate the clinicopathologic features of SMMN-FGT and its relationship with prognosis.Methods:We retrospectively analyzed the clinicopathological features and follow-up records of 25 cases of SMMN-FGT diagnosed from January 2012 to October 2022 in the case database of Obstetrics and Gynecology Hospital of Fudan University.Results:The median age at onset was 46 years old, respectively. Clinical manifestations included irregular vaginal bleeding or drainage, pelvic pain, and ovarian cysts, etc. Germline genetic test confirmed Peutz-Jeghers syndrome (P-J syndrome) in two patients. All patients underwent surgery, and 13 patients had postoperative adjuvant radiotherapy and/or chemotherapy. The most frequent site of lesion was the cervix (21 cases), with 11, 10 and 16 cases occurring in the endometrium, fallopian tubes and ovaries, respectively. Six cases involved three sites simultaneously, and only one case had all four sites involved at the same time. Among the 9 cases with P53 mutation phenotype, 6 cases had gastric-type mucinous adenocarcinoma, 2 cases had lobular endocervical glandular hyperplasia, and 1 case had mucinous adenocarcinoma, whereas all the minimally deviated adenocarcinomas had wild phenotype of P53. The median follow-up time was 59 months, during which 3 cases died and 6 cases developed local recurrence or distant metastasis. According to our analysis, postoperative recurrence or metastasis was correlated with the FIGO stage of the disease, the number of lesion sites and the severe degree of the uterine lesions ( P＜0.05). Conclusions:SMMN-FGT has a relatively good clinical prognosis, and even advanced patients can benefit from surgery and adjuvant therapy. In young patients, the ovaries may be preserved if no evidence of lesions are seen after adequate evaluation. In SMMN-FGT, gastric-type mucinous adenocarcinoma occurring in the cervix may have a better prognosis than gastric-type mucinous adenocarcinoma of the cervix alone, so the accurate diagnosis of SMMN-FGT is critical for clinical management.
