Objective: To observe the clinical effect of moxibustion combined with Duhuo Jisheng decoction for middle-aged and elderly patients with knee osteoarthritis (KOA) and its impact on serum high sensitive C-reactive protein (hs-CRP), interleukin-1β (IL-1β) and tumor necrosis factor-α (TNF-α) levels. Methods: A total of 90 eligible KOA patients were randomized into an observation group (n=45) and a control group (n=45). Cases in the observation group received moxibustion plus oral administration Duhuo Jisheng decoction, while cases in the control group received Duhuo Jisheng decoction. Then the hs-CRP, IL-1β and TNF-α levels were examined and the clinical effect was evaluated. Results: Before treatment, the hs-CRP, IL-1β and TNF-α levels showed no between-group statistical differences (all P>0.05). After 8 weeks of treatment, the hs-CRP, IL-1β and TNF-α levels all dropped significantly in both groups (P<0.01 or P<0.05), and the treatment group showed more substantial changes than the control group (all P<0.05). The total effective rate was 97.8% in the treatment group, versus 86.7% in the control group, showing a statistical difference (P<0.05). Conclusion: Moxibustion plus Duhuo Jisheng decoction has a good clinical effect for middle-aged and elderly KOA patients, and the effect may relate to the decreased hs-CRP, IL-1β and TNF-α levels.

Objective To determine whether fetal rats exposure to isoflurane will cause postnatal learning and memory deficits,and change Bcl-2/Bax ratio in the hippocampus CA1 and retrosplenial cortex in fetal brain of rats. Methods Twenty-eight Sprague Dawley pregnant rats at gestation day 21 (E21) were randomly divided into isoflurane treatment group(n=14) and sham control group(n=14). Rats in isoflurane treatment group were ex-posed to 1.3% isoflurane in a carrying gas of 30% oxygen, balance nitrogen for 6 h in a warmed, humidified cham-ber. For sham control group,animals were treated at the same condition with only carrying gas. In behavior study,the spatial learning and memory ability at juvenile ages was determined with the Morris Water Maze(MWM). In immunohistochemistry study,changes of Bcl-2 and Bax expression in hippocampus CA1 and retrosplenial cortex in the fetus brain after isoflurane treatment at 2 hours was performed by using immunofluorecence staining.Results In the MWM training, the escape latency to platform in the place trials showed no significant difference between the two groups,but the postnatal rats in 1.3% isoflurane group showed obviously improved retention of memory by spending more percentage of time swimming in the probe quadrant as compared to the control animals ((42.33±2.31) s vs (33.2±2.15) s, t=2.21, P<0.05) in the probe test. Compared to controls, 1.3% isoflu-rane exposure for 6 h to the pregnant rats increased the intensity of Bcl-2, decreased the intensity of Bax, and sig-nificantly increased the Bcl-2/Bax ratio in the fetal hippocampal CA1 region (4.40±0. 86 vs 1.31±0.32, t=3. 378, P<0.01) and the fetal retrosplenial cortex (5.07±1.27 vs 1.47±0.48, t=2.656, P < 0.05) respec-tively. Conclusion 1.3% isoflurane exposure in pregnant rats significantly improves the spatial retention memo-ry of their rat pups at a juvenile age and increases the Bcl-2/Bax ratio in the hippocampal CA1 region and the ret-resplenial cortex in the fetal rat brains.

This study reported the analysis of plasma phospholipid metabolism of the rats and the pathological biomarkers between the type 2 diabetes model control group (MC) and the normal control group (NC). SD rats were randomly divided into 2 groups: NC and MC. To investigate state of plasma metabolite profiling in normal body, type 2 diabetes mellitus (T2DM) model group using UPLC-Q-TOF/MS which was used as analysis tool in this research. The compounds were identified by UPLC-Q-TOF/MS based on MS/MS fragment ions information, element composition in MassLynx 4.1 and the Lipid Maps database. The sign of two groups of samples in specific markers for screening was through a software package in R software (BioMark software). The results show that the pathological markers were mainly phosphatidylcholine (PC) and triglycerides (TG); the 2-acyl PC in the MC group was less more obviously than that in the NC group; high carbon number and high degree of unsaturation of the TG was reduced under the condition of type 2 diabetes. In the state of type 2 diabetes, metabolic changes occurred in rat plasma phospholipids obviously, which had a close relationship with the occurrence and development of T2DM.

To investigate the clinicopathological features as well as prognosis of early esophageal squamous cell neoplasm (ESCN) treated with endoscopic resection (ER).Methods 368 patients were collected from 2007 to 2013.Clinicopathological features including invasion depth and margin were evaluated.Survival curves were constructed by using the Kaplan-Meier method.Univariate and multivariate Cox proportional hazard regression models were performed to identify associations with outcome variables.Results There were 252 males and 116 females with a median age of 61 (16-84) years.Patient numbers of hyperplasia,low grade intraepithelial neoplasia,high grade intraepithelial neoplasia,m1,m2,m3,sm1 and sm2 were 47(12.8％),61 (16.6％),61 (16.6％),54(14.7％),38(10.3％),63(17.1％),12(3.3％) and 32(8.7％),respectively.The cumulative overall 1-year,3-year,and 5-year rates of survival in the metachronous esophageal lesions were 4.1％,12.9％ and 32.6％,respectively.The incidence of lymph node/distant metastasis was 1.54％ in m3,6.25％ in sm2,and 0 in other subgroups.The overall 1-year,3-year,and 5-year survival rates were 99.5％,97.3％,and 87.5％,respectively.Significant difference was identified between sm2 and non-sm2 patients in metastatic rate (P =0.021),however,no significant difference existed between m3 patients and sm2 patients (P =0.252).Metachronous esophageal lesion and survival between sm2 and non-sm2 patients demonstrated no statistical difference (P =0.401 and P =0.634).Conclusion ER is an effective and relatively safe treatment for superficial ESCN.The procedure is still appropriate in selecting sin2 patients.It is necessary to monitor the second primary cancer in sm2 patients during follow-up.

27 rabbits were divided into normal group(n = 4),control group (n = 5), silybin group (n = 6), hyperbaric oxygen (HBO) group (n = 6), and HBO combined with silybin group (n = 6). Circulation of hindlimb was interrupted completely for 6 h and reperfused for 1 h. Malondialdehyde (MDA) and superoxide dismutase(SOD) in plasma from ischemic-reperfused injured limb were measured. Adenosine triphosphate (ATP) and creatine phosphate (CP) in samples taken from anterior tibial muscle were determined. Ultrastructural changes of injured muscle were observed. The results showed that HBO combined with silybin treatment had a favourable effect on ischemic and reperfused injured limb muscle with reduction of the lipid peroxidated injury, increase of the SOD activity and the high energy phosphate compounds (ATP and CP), and a promoting recovery of injured muscle cells. HBO and silybin had a synergistic action. It suggests that HBO combined with silybin is an effective method for treatment of ischemic and reperfused injured limb.

Objective:To investigate the change of microalbuminuria (MA) in patients with RA and its clinical significance.Methods:From January 2018 to December 2019, data of 75 cases of RA patients were collected from outpatient and inpatient wardsof our hospital, and the data of 75 cases of physical examination wascollected as control. Erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) anti-cyclic citrullinated peptide (CCP) antibody, blood lipid, Homeostasis model assessment for insulin resistance (HOMA-IR), rheumatoid factor (RF), anti-CCP antibodyand MA levels were measured respectively. RA patients were obtained by ultrasound Carotid intima-media thickness (cIMT) and brachial artery flow mediated diastolic function (FMD) were measured. The statistical analysis was carried out with independent t-test, analysis of variance, Pearson correlation analysis and multiple stepwise regression. Results:The MA level of RA patients was significantly higher than that of the healthy control group [(31±5) mg/L vs (25±4) mg/L, t=5.982, P<0.05]. In RA patients, MA level was positively correlated with course of disease ( r=0.327, P=0.015), HOMA-IR ( r=0.576, P<0.01], CRP ( r=0.212, P=0.027), RF ( r=0.585, P<0.01), disease activity score in 28 joints (DAS28) ( r=0.472, P=0.013), cIMT ( r=0.611, P<0.01) and duration of nonsteroidal anti-inflammatory drugs (NSAIDs) use ( r=0.274, P<0.01), and urineMA level( OR=1.763, P<0.01) were independent correlation factors affecting cIMT. Conclusion:The level of MA in RA patients is significantly higher than that in normal controls, and is correlated with disease activity and subclinical atherosclerosis, which could be another important predictor of disease follow-up and early screening of subclinical atherosclerosis in RA patients.

Purpose To analyze the correlations between PD-L1 expression and clinicopathological factors and their prognostic values in esophageal squamous cell carcinoma (ESCC) patients.Methods PD-L1 expression in the primary tumors from 253 patients with ESCC was evaluated using tissue microarray and immunohistochemistry (IHC).PD-L1 positivity was defined as positive staining of 1％ and 5％ tumor cells.Survival curves were constructed by using the Kaplan-Meier method.Univariate and multivariate Cox proportional hazard regression models were performed to identify associations with outcome variables.Results Overall,tumoral PD-L1 expression was potentially associated with favorable DFS and OS.When the patients were stratified into stage Ⅰ + Ⅱ (60.9％,154/253) and stage Ⅲ + Ⅳa (39.1％,99/253),the prognostic role was not consistent.In patients with stage Ⅰ + Ⅱ disease,tumoral PD-L1 expression was associated with better DFS and OS upon multivariate analysis (1％ as the cutoff:P =0.046 and 0.021,5％ as the cutoff:P=0.011 and0.004).However,PD-L1 expression was not correlated with prognosis in patients with stage Ⅲ + Ⅳa disease (1％ as the cutoff:P =0.586 and 0.682,5％ as the cutoff:P =0.807 and 0.620).Conclusion The prognostic role of tumoral PDL expression is variable in different stages of ESCC,and tumoral PDL expression is an independent favorable predictor in ESCC patients with Stage Ⅰ-Ⅱ disease,but not in stage Ⅲ-Ⅳa or lymph node metastasis.
