ObjectiveTo compare the effects of programmed intermittent epidural bolus （PIEB） and continuous epidural infusion （CEI） on enhanced recovery after cesarean section. MethodsTotally 120 women scheduled to undergo elective cesarean section under combined spinal and epidural anesthesia， aged 18-45 years， with single fetus， full-term pregnancy （≥37 weeks）， ASA grade II or III， were recruited， with 60 cases in each group. At the end of the surgery， after a similar epidural loading dose， patients were randomLy assigned to receive either PIEB （6 mL·h^-1 beginning 30 minutes after the loading dose） or CEI （6 mL·h^-1， beginning immediately after the loading dose） for the maintenance of analgesia with 0.1% ropivacaine. At 2， 6， 12， 24 and 36 h postoperatively， VAS score was used to evaluate the composite pain， and Bromage Score was used to evaluate the degree of lower extremity motor block. The time to first flatus， time to first ambulation and the satisfaction scores were also recorded. ResultsThe VAS scores at 12， 24 and 36 h postoperatively and the lower extremity motor block scores at 6， 12 and 24 h postoperatively in the PIEB group were significantly lower than those in the CEI group （P < 0.01）. The epidural analgesic dosage was less in the PIEB group than that of the CEI group （P=0.002）. The time to first flatus and time to first ambulation were significantly shorter than those in the CEI group （P < 0.05）. The satisfaction scores were significantly higher in the PIEB group than in the CEI group （P < 0.05）. There was no significant difference in the first urination time after urinary catheter removal and the length of hospital stay between the two groups （P > 0.05）. ConclusionCompared with CEI， PIEB provides better postoperative analgesia， less motor block scores， lower epidural analgesic dosage， shorter the time to first flatus and defecation and time to first ambulation， and greater patient satisfaction， which is more consistent with the ERAS concept of analgesia.

Background The association between serum nickel (Ni) and oral cancer incidence is unclear and most of the previous studies were observational studies that did not control for confounding factors between groups. Objective To assess the correlation of serum Ni with oral cancer incidence based on propensity score matching (PSM) and inverse probability of treatment weighting (IPTW). Methods A cohort of 456 newly diagnosed oral cancer patients was recruited from the First Hospital of Fujian Medical University during November 2011 to May 2019, and residents ordered their health check-up in hospitals or local community health centers over the same period were selected as a control group, which included a total of 1410 participants. Serum Ni was evaluated by inductively coupled plasma mass spectrometry. Case-control pairs were selected using a 1:1 PSM (caliper value of 0.02), and the study subjects in the case group and control group were weighted for subsequent analysis by IPTW. The general characteristics of the study subjects were tested for equilibrium before and after matching by chi-square test and standardized mean difference (SMD). This was followed by exploring the potential nonlinear dose-response relationship between serum Ni and oral cancer using restricted cubic splines as well as analyzing the association between serum Ni and oral cancer incidence by conditional logistic regression and weighted logistic regression. Results After controlling for between-group covariates by PSM and IPTW, the dose-response curves demonstrated that the risk of developing oral cancer tended to decline and then increase with the increasing serum Ni level. The outcome of the analysis using PSM demonstrated that as compared to the control group, the risk of developing oral cancer in the 0.09-16.80 μg·L⁻¹ serum Ni group was negatively correlated with serum Ni level (OR=0.36, 95%CI: 0.24-0.54), whereas the risk of developing oral cancer in the >16.80 μg·L⁻¹ serum Ni group was positively correlated with serum Ni level (OR=5.43, 95%CI: 2.76-10.68). After applying IPTW, a negative association was found between the risk of oral cancer and serum Ni concentration within a serum Ni window ranging from 0.09 to 20.55 μg·L⁻¹ (OR=0.39, 95%CI: 0.29-0.52), while a positive association with an OR and 95%CI of 5.54 (3.62-8.49) for the Ni concentration > 20.55 μg·L⁻¹. Conclusion In this study, a J-shaped relationship between serum Ni concentration and the risk of developing oral cancer is found, which shows that high serum Ni concentration (>20.55 μg·L⁻¹) may be a risk factor for oral cancer.

Objective To evaluate the effect of serum chromium on oral cancer after adjusting the covarite between groups based on propensity score matching (PSM). Methods We performed a case-control study in 395 cases of newly diagnosed primary oral cancer from the First Affiliated Hospital of Fujian Medical University and 1 240 controls from the same community from January 2010 to February 2018. Using the PSM to select 309 controls randomly which were matched with the cases by 1 ∶1 matching. Conditional Logistic regression model was used to explore the association between chromium and oral cancer. Results The level of serum chromium was 178.91 (121.83-284.19) μg/L in the case group, which was lower than 324.27 (264.82-397.69) μg/L in control group, the difference was statistically significant (P＜0.001). Dose-response analysis showed that the risk of oral cancer gradually decreased with the increase of serum chromium, which presented a negative correlation. There was a negative correlation between serum chromium level and the risk for oral cancer by conditional Logistic regression,the aOR of serum chromium in the Q2, Q3 and Q4 compared with the Q1 were 0.14 (0.08-0.26), 0.15 (0.08-0.28) and 0.10 (0.05-0.20),with significant trend (Ptrend＜0.001). Stratified analysis showed the negative correlation between serum chromium and oral cancer by smoking, drinking tea, not drinking alcohol status and fish, fruits and green vegetables intake frequencies. Conclusions The high level of serum chromium is a protective factor for the incidence of oral cancer, and the higher of serum chromium, the lower risk of developing oral cancer.

OBJECTIVE: To analyze the displacement, stress and mechanism of lumbosacral joint disorder patients after bending and standing manipulation in the finite element model. METHODS: A three-dimensional finite element model of a patient with lumbosacral joint disorder was established. The finite element analysis method was used to observe and analyze the three loading conditions of the model:axial, 34 degree inclined upward and vertical upward. RESULTS: In the lumbosacral joint disorder model, the L₅ vertebral body was concentrated in the middle of the lower endplate, the intervertebral disc was concentrated in the center of the intervertebral disc, and the stress of S₁ and related structures were concentrated in the anterior and posterior edges of the vertebral body. After simulated manipulation, stress mainly concentrated in the anterior, posterior and central circular areas of L₅ vertebral upper endplate. The posterior structures of vertebral body concentrated in the ventral part of pedicle, isthmus and dorsal part of lamina. The stress of intervertebral disc dispersed in the posterior edge of vertebral body. Displacement results:In the lumbosacral joint disorder model, the left transverse process, the upper and lower articular process and the left part of spinous process were significantly displaced to the left, and the intervertebral disc was protruded forward. After simulated manipulation, the lower notch of L₅ vertebral body moved forward and upward; the area of intervertebral foramen increased; the inferior articular process of L₅ vertebral body moved forward; the superior articular process of sacrum moved forward and downward; the distance of articular process joints increased; and the displacement of sacrum concentrated on the posterior edge of vertebral body and the median sacral crest. CONCLUSIONS Successful lumbosacral joint modeling can be carried out by finite element analysis, and the mechanism of bending and erecting manipulation is clear, which is effective and safe for the treatment of lumbosacral joint disorders.

Cyclophosphamide (CPA) is one of the most commonly used alkylating agents in the treatment of malignant cancer. CPA is metabolized by cytochrome P450 enzymes into 4-hydroxycyclophosphamide in vivo which can exhibit anti-tumor activity. Metabolic activation of CPA can cause adverse reactions such as myelosuppression, cystitis, and liver injury. The aim of this study was to evaluate the dynamic changes of hepatic injury induced by CPA in mice. Male BALB/c mice were injected CPA (200 mg·kg^-1) intraperitoneally. Both serum and liver samples were collected at 0, 2, 6, 12 and 24 hours after dosing. The animal experiment protocol was approved by the Institutional Animal Care and Use Committee at Sun Yat-sen University. The results showed that hepatotoxicity was observed at 2 hours after CPA dosing, and the most serious liver injury was measured at 12 hours. The level of serum aspartate aminotransferase (AST), alanine aminotransferase (ALT) and malondialdehyde (MDA) was significantly increased, glutathione (GSH) level was significantly decreased, hepatocyte edema and vacuolar degeneration were widely observed in liver tissue, and began to recover 24 hours after dosing. In addition, due to oxidative stress damage caused by CPA, nuclear factor-erythroid 2-related factor 2 (NRF2) signaling pathway was activated and the mRNA and protein expression of its downstream targets such as quinine oxidoreductase 1 (NQO1), heme oxygenase-1 (HO-1), glutamate-cysteine ligase catalytic subunit (GCLC) and glutamate cysteine modifier subunit (GCLM) were up-regulated, which alleviated oxidative stress injury. In a summary, this study demonstrate the dynamic change of CPA-induced liver injury and the NRF2-mediated protective mechanisms, providing new insights into the CPA-induced liver injury.

Objective: To explore the association of TBX5 polymorphisms and environmental exposure index with susceptibility to oral cancer. Methods: A case-control study was conducted to collect 300 oral cancer patients hospitalized in the Department of Oral and Maxillofacial Surgery, the First Affiliated Hospital of Fujian Medical University from September 2010 to December 2016. A total of 445 non-tumor patients were selected as the control group. Questionnaires were used to collect the information of all subjects and 5 ml peripheral blood was collected to detect single nucleotide polymorphisms (SNPs) of the rs10492336 locus of TBX5 gene. According to the environmental exposure index score, subjects were divided into two groups, low risk group (0-2.31) and high risk group (2.32-11.76). To analyze the association of TBX5 gene rs10492336 SNPs, environmental exposure index and oral cancer and its interactions. Results: The age of all subjects in the case group and control group were (56.19±13.10) years and (54.56±12.48) years old. Compared with CC genotype, the OR (95%CI) values of the co-dominant genetic model AC genotype and the dominant genetic model AC+AA genotype were 0.69 (0.49-0.98) and 0.70 (0.51-0.97), respectively. Compared with the low risk group, the OR (95%CI) risk of oral cancer in the high risk group was 3.72 (2.55-5.43). The results of gene-environment interaction analysis showed that compared with the group with CC genotype and high risk of environmental exposure index, the OR (95%CI) value of oral cancer in the group with AC+AA genotype and low risk of environmental exposure index was 0.18(0.10-0.31). Furthermore there was a multiplicative interaction between rs10492336 SNPs and environmental exposure index (β=-0.405, P<0.001). Conclusion This study suggests that the TBX5 gene rs10492336 SNPs and environmental exposure index were associated with oral cancer. And there was a multiplication interaction between rs10492336 SNPs and environmental exposure index.
