OBJECTIVE: To explore influence of external factors of wind, cold and dampness on clinical symptoms in knee osteoarthritis (KOA) patients with different constitutions of traditional Chinese medicine. METHODS: A cross-sectional stratified study was performed to select 108 patients with GradeⅡKOA in Kellgren & Lawrence (K-L) classification, including 22 males and 86 females, aged from 47 to 75 years old with an average of (60.7±6.0) years old;body mass index(BMI) ranged from 17.87 to 31.22 kg·m^-2 with an average of (23.80±2.86) kg·m^-2. According to Classification and Judgment of TCM Physique (ZYYXH/T157-2009), the types of TCM physique were determined and divided into 4 layers according to the deficiency and actual physique. Among them, there were 24 patients without biased physique, 12 males and 12 females, aged from 51 to 73 years old with an average of(62.8±6.0) years old, BMI ranged from 17.87 to 31.14 kg·m^-2 with an average of (24.32±3.25) kg·m-2;there were 46 patients with virtual bias constitution, including 7 males and 39 females, aged from 47 to 70 years old with an average of (60.0±5.8) years old, BMI ranged from 19.38 to 31.22 kg·m^-2 with an average of(23.42±2.97) kg·m^-2;There were 26 patients with solid bias constitution, including 2 males and 24 females, aged from 48 to 75 years old with an average of (60.4±5.8) years old, BMI ranged from 21.16 to 30.76 kg·m^-2 with an average of (24.15±2.33) kg·m^-2;there were 9 patients with special constitution, 1 male and 8 female, aged from 53 to 75 years old with an average of (59.8±7.5) years old, BMI ranged from 19.26 to 26.67 kg·m^-2 with an average of (23.79±2.49) kg·m^-2. Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) was used to evaluate severity of clinical symptoms. The wind-cold-dampness external factor score was calculated through the questionnaire of wind-cold-dampness syndrome scale to evaluate degree of influence of wind-cold-dampness external factor. Pearson correlation analysis and partial correlation analysis were used to calculate the correlation coefficient between severity of external factors affecting wind, cold and dampness and severity of clinical symptoms in patients with different TCM constitution stratification. RESULTS: There was no statistical significance between total score of wind-cold-dampness and WOMAC score in patients with no biased constitution and special condition. Total wind-cold-dampness score of patients with virtual biased constitution was positively correlated with WOMAC stiffness score (r=0.327, P=0.032), and total wind-cold-dampness score of patients with solid biased constitution was positively correlated with WOMAC pain score (r=0.561, P=0.005) and WOMAC overall score (r=0.446, P=0.033). After further adjusting for the interaction of external factors of wind-cold-dampness, there was no statistical significance between wind-cold-dampness scores and WOMAC scores in patients with solid biased constitution. The score of dampness and pathogenic factors was positively correlated with WOMAC stiffness score (r=0.414, P=0.007). CONCLUSION The external factors of wind-cold dampness have different effects on the clinical symptoms of KOA patients with different TCM constitutions. Compared with other constitutions, the rigid symptoms of patients with asthenic biased constitutions are more susceptible to dampness pathogenic factors.

Aim To study the nephrotoxicity effects of the main monomers in Zuojin Pills. Methods CCK-8 and high-content toxicity screening were used to preliminarily screen the main alkaloids in Zuojin Pills that may cause renal cell damage. Further, by confirmation of cell morphology, release rate of lactate dehydrogenase and cytochrome C, and expression of apoptosis-related proteins, the alkaloids causing cell damage were preliminarily identified, providing in vitro toxicological evidence for the compatibility of components of traditional Chinese medicine and compatibility attenuation. Results Preliminary screening using CCK-8 method and high-content technology showed that evodiamine (EVO) could significantly reduce cell number, increase cell membrane permeability, and reduce mitochondrial membrane potential. In addition, cell morphology, apoptosis and cytochrome C expression were consistent with the results of high-content screening. Western blot experiments indicate that EVO could induce apoptosis and cause renal cell damage. Conclusions EVO can obviously cause renal cell damage, and may induce apoptosis by affecting mitochondria, cytochrome C and cell membrane permeability.

Objective: To examine the long term outcome of splenic hilar lymphadenectomy (SHL) for locally advanced Siewert type Ⅱ and Ⅲ adenocarcinoma of esophagogastric junction (AEG) with a tumor diameter ≥4 cm. Methods: A total of 489 locally advanced Siewert type Ⅱ and Ⅲ AEG patients with a tumor diameter ≥4 cm who underwent radical resection from January 2010 to April 2016 were included. There were 383 males and 106 females. There were 225 patients aged≥65 years and 264 patients aged <65 years. SHL was conducted in 270 patients(SHL group). Wilcoxon rank-sum test or χ² test were conducted for inter-group comparison. Cox proportional hazard regression was used to analyze the long term outcome of SHL and the prognosis factors of overall survival. Kaplan-Meier curve was drawn finally. The results of survival analysis were verified by Log-rank test. Results: Followed-up to April 2021,the median follow-up time was 78.0 months (range: 74.0 to 85.0 months), the follow-up rate was 95.5%(467/489). The splenic hilar lymphnode metastasis rate of the SHL group was 12.6% (34/270). Younger patients (<65 years old), less complications, higher proportion of patients received adjuvant chemotherapy were demonstrated in the SHL group (χ²: 5.644 to 6.744, all P<0.05). Multivariate analysis showed that SHL was the independent prognosis factor of overall survival for patients with Siewert type Ⅱ and Ⅲ AEG and a tumor diameter≥4 cm (HR=0.68, 95%CI: 0.52 to 0.88, P=0.004) along with preoperative CA19-9, pathological T stage, pathological N stage, adjuvant chemotherapy and postoperative complication. Further subgroup analysis demonstrated that the SHL group had better 5-year overall survival than non-SHL group (62.4% vs. 39.2%, χ²=17.983, P=0.006) in Siewert type Ⅲ AEG rather than in Siewert type Ⅱ AEG(57.3% vs. 53.7%, χ²=3.031, P=0.805). Conclusion: In experienced center, splenic hilar lymphadenectomy can improve the prognosis of Siewert type Ⅲ AEG with a tumor diameter ≥4 cm.

Objective: To evaluate the postoperative quality of life in patients after totally laparoscopic total gastrectomy (TLTG). Methods: A retrospective cohort study based on propensity score matching was performed. Clinical and follow-up data of patients who underwent laparoscopic radical gastrectomy at Union Hospital of Fujian Medical University from January 2014 to May 2015 were collected. Case indusion criteria: (1) primary gastric cancer confirmed by postoperative pathology; (2) receiving TLTG or laparoscopic-assisted total gastrectomy (LATG);(3) R0 resection; (4) completing follow-up for 12 months and complete follow-up data. Exclusion criteria: (1) gastric stump cancer; (2) concurrent tumor; (3) distal metastasis found during operation; (4) history of upper abdominal operation. According to surgical procedures, patients were divided into the LATG group (1076 cases) and the TLTG group (106 cases). To eliminate potential bias in baseline data between the two groups, the propensity score was calculated using a logistic regression model with the following covariates, including age, sex, body mass index, American Society of Anesthesiologists score, tumor location, tumor size, pathology type, and stage. The two groups were matched using a 1:2 propensity assessment ratio and a caliper width of 0.01 standard deviation was specified. The primary outcomes were the quality of life of the two groups at 3, 6 and 12 months after gastrectomy, including physical symptoms and social function. Higher function score indicated better function, and higher symptom score presented worse symptoms. Quality of life score = (100 - somatic symptom scale score + social function scale score) / 2. The secondary outcomes were postoperative nutritional recovery and food tolerance at 3, 6 and 12 months after gastrectomy. The categorical variables were expressed as n(%), and compared using the χ² test or Fisher exact test. The continuous variables conforming to the normal distribution were represented by Mean ± SD and compared with the paired t-test. Repeated measurement of variance was used to compare nutrition-related indicators within the group among pre-operation, postoperative 1, 3, 6, 12 months. Results: After PSM, there were no significant differences in clinicopathological baseline data between the TLTG group (n=104) and the LATG group (n=208) (all P>0.05). The physical symptoms scores in the TLTG group before operation and 3, 6 and 12 months after operation were 8.6±5.8, 15.5±8.4, 10.1±5.9 and 6.1±2.4 respectively (F=43.493, P<0.001). In the LATG group, the above mentioned scores were 9.7±6.9, 23.7±10.4, 13.3±8.3 and 8.5±4.2 respectively (F=112.588, P<0.001). Compared with the LATG group, the symptom scores in the TLTG group were lower at 3 and 6 months after operation, and the differences were statistically significant (t=-3.653, P<0.001; t=-2.513, P=0.012). At 12 months after operation, although the physical symptom score in the TLTG group was also lower than that in LATG group, the difference was not statistically significant (t=-1.487, P=0.138). The social function scores in the TLTG group before operation and 3, 6 and 12 months after operation were 90.3±8.9, 77.5±14.3, 87.4±10.3 and 91.7±6.7 respectively (F=28.524, P<0.001). In the LATG group, the above mentioned scores were 92.5±6.3, 68.5±16.8, 79.8±14.7 and 84.7±11.1 respectively (F=57.975, P<0.001). Compared with the LATG group, the social function scores of patients in the LATG group were higher at 3, 6 and 12 months after operation (t=3.543, P<0.001; t=3.216, P=0.001; t=2.235, P=0.026). The total scores of quality of life at 3, 6 and 12 months after operation in the TLTG group were 81.0±15.6, 88.3±8.1 and 93.3±9.1 respectively, and the above mentioned scores in the LATG group were 72.4±13.6, 83.3±11.5 and 88.1±7.7 respectively, whose differences at corresponding time point were all significant between the two groups (all P<0.05). The change of total body mass[(-8.4±1.4)% vs. (-13.2±1.6)%, t=2.273, P=0.024], serum albumin[(-5.1±0.7)% vs. (-7.4±0.8)%,t=2.095, P=0.037], meal quantity [(-15.6±4.7)% vs. (-24.1±6.0)%, t=2.885, P=0.004] and meal times [(20.8±7.1)% vs. (30.6±11.5)%, t=3.043, P<0.001] in the TLTG group were significantly lower than those in the LATG group one year after operation (all P<0.05). At 3, 6 and 12 months after operation, the diet proportions of solid and soft food in the TLTG group were higher than those in the LATG group (all P<0.05). Conclusions: Compared with LATG, patients with gastric cancer undergoing TLTG have better health-related quality of life and faster recovery of nutrition.

Objective:To explore the effect of Bushen Huatan prescription on serum lipopolysaccharide （LPS） and Toll-like receptor 4 （TLR4）/ myeloid cell differentiation protein 88 （MyD88）/nuclear transcription factor-κB （NF-κB） signaling pathway in rats with ovariectomy-induced osteoporosis. Method:Sixty SPF 6-month-old female rats were randomly divided into sham operation group， model group， estradiol valerate group and Bushen Huatan prescription low， medium and high dose groups.One week after modeling by bilateral ovariectomy， 8 rats in each group were selected to receive intragastric administration.The estradiol valerate group was given 0.184 mg·kg^-1 by gavage， and Bushen Huatan prescription low， middle and high dose groups were given 4.7， 9.4 and 18.8 g·kg^-1 by gavage， sham operation group and model group were given 0.9% saline 4 mL by gavage respectively.After 12 weeks of intervention， the rats were sacrificed for detection.Serum LPS was detected by enzyme linked immunosorbent assay （ELISA）， while protein expressions of TLR4， MyD88 and phosphorylated （p）-NF-κB p65 in bone tissue were detected by Western blot， and the mRNA expressions of TLR4， MyD88， NF-κB p65， IL-1β， and IL-6 in bone tissue were detected by quantitative real-time polymerase chain reaction（PCR）. Result:Compared with sham operation group， the serum LPS level as well as protein expression of TLR4， MyD88， p-NF-κB p65 and mRNA expression of TLR4， MyD88， NF-κB p65， IL-1β， and IL-6 significantly increased in model group（P<0.05）.Compared with the model group， serum LPS level， protein expression of TLR4， MyD88， and p-NF-κB p65， mRNA levels of TLR4， MyD88， and NF-κB p65 in bone tissues as well as downstream inflammatory factors IL-1β， IL-6 mRNA expression decreased to different degrees in estradiol valerate group and Bushen Huatan prescription high dose group（P<0.05）. Conclusion:Bushen Huatan prescription can reduce serum LPS content， regulate mRNA and protein expression of TLR4， MyD88， NF-κB p65 and p-NF-κB p65 in TLR4/MyD88/NF-κB pathway， and down-regulate mRNA levels of IL-1β and IL-6 in bone tissues to improve bone microstructure and inhibit the development of postmenopausal osteoporosis （PMOP）.

This study investigated the intervention effect and possible mechanism of ophiopogonin D (OPD) in protecting cardiomyocytes against ophiopogonin D' (OPD')-induced injury, and provided relevant experimental data for the clinical use of Ophiopogon japonicas. Cell counting kit-8 (CCK-8) assay was used to evaluate the effect of OPD and OPD' on H9c2 cell viability. The content of reaction oxygen species (ROS) in cells were detected by flow cytometry. The contents of Fe²⁺ in cells were detected by FerroOrange's fluorescence imaging. The content of glutathione (GSH) and glutathione peroxidase (GSH-Px) were detected by kits. The expression of transferrin receptor 1 (TFR1), cyclooxygenase 2 (COX2), NADPH oxidase 1 (NOX1), long-chain acyl-CoA synthetase 4 (ACSL4), cationic amino acid transporter 11 (SLC7A11), glutathione peroxidase 4 (GPX4), and ferritin heavy chain 1 (FTH1) was detected by Western blot. Results showed that OPD' (1 μmol·L^-1) significantly induced the expression of ferroptosis-related proteins, the contents of Fe²⁺, ROS, and GSH-Px were increased, and the content of GSH were decreased. In addition, different concentrations of OPD (0.5, 1, and 2 μmol·L^-1) could partially reverse the myocardial cell injury caused by OPD', and the best effect was obtained when the dose range was 1-2 μmol·L^-1. The experimental results show that OPD can interfere with the ferroptosis caused by OPD', and then have a protective effect on H9c2 cells.

Objective:To construct a prognosis associated micro RNA(miRNA) prediction model based on bioinformatics analysis and evaluate its application value in pancreatic cancer patients.Methods:The retrospective cohort study was conducted. The clinicopathological data of 171 pancreatic cancer patients from the Cancer Genome Atlas (TCGA) (https: //cancergenome.nih.gov/) between establishment of database and September 2017 were collected. There were 93 males and 78 females, aged from 35 to 88 years, with a median age of 65 years. Of the 171 patients, 64 had complete clinicopathological data. Patients were allocated into training dataset consisting of 123 patients and validation dataset consisting of 48 patients using the random sampling method, with a ratio of 7∶3. The training dataset was used to construct a prediction model, and the validation dataset was used to evaluate performance of the prediction model. Nine pairs of miRNA sequencing data (GSE41372) of pancreatic cancer and adjacent tissues were downloaded from Gene Expression Omnibus database. The candidate miRNAs were selected from differentially expressed miRNAs in pancreatic cancer and adjacent tissues for LASSO-COX regression analysis based on the patients of training dataset. A prognosis associated miRNA prediction model was constructed upon survival associated miRNAs which were selected from candidate differentially expressed miRNAs. The performance of prognosis associated miRNA prediction model was validated in training dataset and validation dataset, the accuracy of model was evaluated using the area under curve (AUC) of the receiver operating characteristic curves and the efficiency was evaluated using the consistency index (C-index). Observation indicarors: (1) survival of patients; (2) screening results of differentially expressed miRNAs; (3) construction of prognosis associated miRNA model; (4) validation of prognosis associated miRNA model; (5) comparison of clinicopathological factors in pancreatic cancer patients; (6) analysis of factors for prognosis of pancreatic cancer patients; (7) comparison of prediction performance between prognosis associated miRNA model and the eighth edition TNM staging. Measurement data with normal distribution were represented as Mean± SD, comparison between groups was analyzed by the student- t test, and comparison between multiple groups was analyzed by the AVONA. Measurement data with skewed data were represented as M (range), and comparison between groups was analyzed using the Mann-Whitney U test. Count data were described as absolute numbers or percentages, and comparison between groups was conducted using the chi-square test. Ordinal data were analyzed using the rank sum test. Correlation analysis was conducted based on count data to mine the correlation between prognosis associated miRNA model and clinicopathological factors. COX univariate analysis and multivariate analysis were applied to evaluate correlation with the results described as hazard ratio ( HR) and 95% confidence interval ( CI). HR<1 indicated the factor as a protective factor, HR>1 indicated the factor as a risk factor, and HR equal to 1 indicated no influence on survival. The Kaplan-Meier method was used to draw survival curve and calculate survival rates, and the Log-rank test was used for survival analysis. Results:(1) Survival of patients: 123 patients in the training dataset were followed up for 31-2 141 days, with a median follow-up time of 449 days. The 3- and 5-year survival rates were 16.67% and 8.06%. Forty-eight patients in the validation dataset were followed up for 41-2 182 days, with a median follow-up time of 457 days. The 3- and 5-year survival rates were 15.63% and 9.68%. There was no significant difference in the 3- or 5-year survival rates between the two groups ( χ2=0.017, 0.068, P>0.05). (2) Screening results of differentially expressed miRNAs. Results of bioinformatics analysis showed that 102 candidate differentially expressed miRNAs were selected, of which 63 were up-regulated in tumor tissues while 39 were down-regulated. (3) Construction of prognosis associated miRNA model: of the 102 candidate differentially expressed miRNAs, 5 survival associated miRNAs were selected, including miR-21, miR-125a-5p, miR-744, miR-374b, miR-664. The differential expression patterns of pancreatic cancer to adjacent tissues were up-regulation, up-regulation, down-regulation, up-regulation, and down-regulation, respectively, with the fold change of 4.00, 3.43, 3.85, 2.62, and 2.35. A prognostic expression equation constructed based on 5 survival associated miRNAs = 0.454×miR-21 expression level-0.492×miR-125a-5p expression level-0.49×miR-744 expression level-0.419×miR-374b expression level-0.036×miR-664 expression level. (4) Validation of prognosis associated miRNA model: The C-index of prognosis associated miRNA model was 0.643 and 0.642 for the training dataset and validation dataset, respectively. (5) Comparison of clinicopathological factors in pancreatic cancer patients: results of COX analysis showed that the prognosis associated miRNA model was highly related with pathological T stage and location of pancreatic cancer ( Z=45.481, χ2=10.176, P<0.05). (6) Analysis of factors for prognosis of pancreatic cancer patients: results of univariate analysis showed that pathological N stage, radiotherapy, molecular targeted therapy, score of prognosis associated miRNA model were related factors for prognosis pf pancreatic cancer patients ( HR=2.471, 0.290, 0.172, 2.001, 95% CI: 1.012-6.032, 0.101-0.833, 0.082-0.364, 1.371-2.922, P<0.05). Results of multivariate analysis showed that molecular targeted therapy was an independent protective factor for prognosis of pancreatic cancer patients ( HR=0.261, 95% CI: 0.116-0.588, P<0.05) and score of prognosis associated miRNA model≥1.16 was an independent risk factor for prognosis of pancreatic cancer patients ( HR=1.608, 95% CI: 1.091-2.369, P<0.05). (7) Comparison of prediction performance between prognosis associated miRNA model and the eighth edition TNM staging: in the training dataset, there was a significant difference in the prediction probability for 3- and 5-year survival of pancreatic cancer patients between prognosis associated miRNA model and the eighth edition TNM staging ( Z=-1.671, -1.867, P<0.05). The AUC of the prognosis associated miRNA model and the eight edition TNM staging for 3- and 5-year survival prediction was 0.797, 0.935 and 0.737 , 0.703, with the 95% CI of 0.622-0.972, 0.828-1.042 and 0.571-0.904 , 0.456-0.951. The C-index was 0.643 and 0.534. In the validation dataset, there was a significant difference in the prediction probability for 3- and 5-year survival of pancreatic cancer patients between prognosis associated miRNA model and the eighth edition TNM staging ( Z=-1.729, -1.923, P<0.05). The AUC of the prognosis associated miRNA model and the eight edition TNM staging was 0.750, 0.873 and 0.721 , 0.703, with the 95% CI of 0.553-0.948, 0.720-1.025 and 0.553-0.889, 0.456-0.950, respectively. The C-index was 0.642 and 0.544. Conclusions:A prognosis associated miRNA prediction model can be constructed based on 5 survival associated miRNAs in pancreatic cancer patients, as a complementation to current TNM staging and other clinicopathological parameters, which provides individual and accurate prediction of survival for reference in the clinical treatment.

OBJECTIVE: To investigate the clinical features and outcome of neonatal acute respiratory distress syndrome (ARDS) in southwest Hubei, China. METHODS: According to the Montreux definition of neonatal ARDS, a retrospective clinical epidemiological investigation was performed on the medical data of neonates with ARDS who were admitted to Department of Neonatology/Pediatrics in 17 level 2 or level 3 hospitals in southwest Hubei from January to December, 2017. RESULTS: A total of 7 150 neonates were admitted to the 17 hospitals in southwest Hubei during 2017 and 66 (0.92%) were diagnosed with ARDS. Among the 66 neonates with ARDS, 23 (35%) had mild ARDS, 28 (42%) had moderate ARDS, and 15 (23%) had severe ARDS. The main primary diseases for neonatal ARDS were perinatal asphyxia in 23 neonates (35%), pneumonia in 18 neonates (27%), sepsis in 12 neonates (18%), and meconium aspiration syndrome in 10 neonates (15%). Among the 66 neonates with ARDS, 10 neonates (15%) were born to the mothers with an age of ≥35 years, 30 neonates (45%) suffered from intrauterine distress, 32 neonates (49%) had a 1-minute Apgar score of 0 to 7 points, 24 neonates (36%) had abnormal fetal heart monitoring results, and 21 neonates (32%) experienced meconium staining of amniotic fluid. Intraventricular hemorrhage was the most common comorbidity (12 neonates), followed by neonatal shock (9 neonates) and patent ductus arteriosus (8 neonates). All 66 neonates with ARDS were treated with mechanical ventilation in addition to the treatment for primary diseases. Among the 66 neonates with ARDS, 10 died, with a mortality rate of 15% (10/66), and 56 neonates were improved or cured, with a survival rate of 85% (56/66). CONCLUSIONS Neonatal ARDS in southwest Hubei is mostly mild or moderate. Perinatal asphyxia and infection may be the main causes of neonatal ARDS in this area. Intraventricular hemorrhage is the most common comorbidity. Neonates with ARDS tend to have a high survival rate after multimodality treatment.
