Objective:To observe the effects of electroacupuncture(EA)on sleep electroencephalogram(EEG)and event-related potential(ERP)in patients with somatoform disorders(SFD). Methods:Seventy-five SFD patients were recruited as an EA group to receive EA at Shenting(GV24)and Baihui(GV20)once daily,30 min each time,with 6 straight days as a treatment course,and 4 courses were conducted at 1-day intervals.Before treatment,patients underwent a survey using a physical symptom checklist on their primary symptoms.Before and after treatment,their sleep EEG was monitored using Quisi,and the ERP mismatch negativity(MMN)and P300 were detected.The Quisi sleep EEG and ERP were also examined among 40 normal volunteers as the normal group data. Results:During the trial,13 cases were removed from the EA group due to incomplete data,and 62 cases were finally included for statistical analyses.Of the 62 SFD patients,the main disturbing symptoms were cognitive impairments,sleep disorders,respiratory symptoms,digestive symptoms,five-sense organ problems,and cardiovascular symptoms in order.Before treatment,the EA group had increased MMN and P300 latencies and decreased amplitudes compared with the normal control group(P<0.01 or P<0.05);according to Quisi,the EA group also had reduced total sleep time(TST),shorter rapid eye movement sleep(REM)latency(RL)and REM time(RT),smaller number of REM period(NRP),extended sleep latency(SL),longer awaking time(AT),lower sleep efficiency(SE),larger percent of non-rapid eye movement sleep(NREM)stage 1(S1)and smaller percent of NREM stage 2(S2),and the percent of slow wave sleep(SWS),i.e.NREM stage 3(S3)plus stage 4(S4),also went down,all presenting significant differences between groups(P<0.01 or P<0.05).After 4 courses of treatment,the MMN and P300 latencies were reduced,and their amplitudes became larger in the EA group compared with the baseline(P<0.05);they had insignificant differences compared with the normal control group(P>0.05).Quisi showed that the TST and RL increased,and the SL and AT decreased in the EA group,and the predominant change in sleep architecture was reduced S1 percent,increased S2,and improved SE,all showing significant intra-group differences(P<0.01 or P<0.05);however,the intra-group difference in the NRP was statistically insignificant(P>0.05).Except the TST,RT,S1 percent,and SWS,there was no statistical significance in comparing the other Quisi parameters(including RL,NRP,SL,AT,SE,and S2 percent)between the two groups(P>0.05). Conclusion:SFD patients have a variety of clinical symptoms,and most of them show abnormal sleep EEG and ERP;EA can correct abnormal sleep EEG parameters and the MMN and P300 of ERP in SFD patients.

OBJECTIVETo compare the penetration abilities of resin infiltration into natural initial caries lesions with those of adhesive in vitro.
METHODSThirty-six extracted human molars and premolars showing proximal white spot lesions were selected. Teeth roots were removed, and the crowns were cut across the caries lesions perpendicular to the surface. Corresponding lesion halves were etched for 2 min with 15% hydrochloric acid gel and were subsequently treated with either adhesive or resin infiltration. Specimens were observed with confocal laser scanning microscopy (CLSM) in dual fluorescence mode. In confocal microscopic images, penetration depth (PD) and lesion depth (LD) were defined as the distance from the surface to the deepest point of red and green fluorescence, respectively. The penetration percentages (PP) were calculated.
RESULTSAt the same level of caries, mean maximum lesion LD were comparable for both lesion halves (P > 0.05). But mean maximum PD and PP of the resin infiltration were significantly higher than those of the adhesive (P < 0.01).
CONCLUSIONPenetration of enamel caries lesions is observed in the adhesive and the resin infiltration. But the resin infiltration is capable of penetrating almost completely into enamel parts of natural caries lesions.

Background: Inflammation is an essential component of liver diseases. Paeoniflorin (PF), a mono-terpenoid component derived from peony root (Paeonia lactiflora Pall.), has anti-inflammatory, immu-noregulatory, and hepatoprotective activities. However, whether PF affects liver inflammation and its underlying mechanisms is unclear. In this study, we investigated the effects of PF on lipopolysaccharide (LPS)-induced inflammation in LO2 cells and the underlying molecular mechanism.Methods: LPS was used to induce inflammation. After PF pretreatment for 2 h, the cells were treated with PF and LPS. Cell counting kit-8 was used to measure cell viability. Tumor necrosis factor-α (TNF-α) and interleukin (IL)-6 were tested by Enzyme-linked immunosorbent assay. Western blot was used to evaluate TNF-α, Ras homolog family member A (RhoA), NOD-, LRR-and pyrin domain-containing protein 3 (NLRP3), apoptosis-associated speck-like protein containing a CARD (ASC), caspase-1, and IL-1β pro-teins expression. Results: In LPS-induced LO2 cells, PF reduced TNF-α and IL-6 inflammatory cytokine production in a dose-dependent manner. LPS-induced TNF-α expression was also suppressed by PF. In addition, PF significantly inhibited LPS-induced RhoA activation (P = .0014). Finally, PF suppressed LPS-induced NLRP3 inflammasome activation by downregulating NLRP3, ASC, caspase-1, and IL-1β expression. Conclusion: These findings suggest that PF alleviates inflammation induced by LPS and further suggest the anti-inflammatory effect of PF may follow via reduced RhoA and NLRP3 inflammasome activity.

Objective:To establish the best evidence-based approach for early fluid resuscitation management in patients with severe acute pancreatitis (SAP).Methods:A literature search was conducted utilizing evidence-based nursing methods to identify relevant evidence on the management of early fluid resuscitation in patients with SAP. The search followed the hierarchical order of the " 6S" evidence pyramid, including databases such as China National Knowledge Infrastructure (CNKI), China Biomedical Literature Database (SinoMed), Wanfang Database, UpToDate, NICE, RNAO Guidelines Network, Pancreatology International, WHO Association Website, JBI, Cochrane, PubMed, EMBASE, and CINAHL. The search was limited to articles published from the establishment of each database to March 2022. The literature quality evaluation tools and an evidence pre-grading system from the JBI Evidence-Based Health Care Center were employed to assess the quality of the literature included in the study. Additionally, the FAME structure was utilized to evaluate the feasibility, appropriateness, clinical significance, and validity of the evidence.Results:Nine articles were finally incorporated into the analysis, including four guidelines, one evidence summary, two systematic reviews, and two expert consensus articles. 21 pieces of evidence pertaining to early fluid resuscitation management in patients with SAP was summarized, encompassing five key aspects: resuscitation timing, type of fluid infusion, total volume and speed of fluid infusion, dynamic monitoring, and fluid resuscitation goals. It was advisable for patients diagnosed with SAP to promptly receive fluid resuscitation, ideally within 72 hours of diagnosis. The initial choice for fluid resuscitation was lactated Ringer′s solution, with the addition of human albumin as a supplementary colloid solution. The quantity of fluid administered within the first 24 hours of rehydration should constitute approximately 33.3% of the total rehydration volume within the 72 hours time-frame. In the case of patients experiencing early shock or dehydration, it was advised that the fluid rate administered should be 5-10 ml·kg -1·h -1 within the first 24 hours of admission. Additionally, an infusion of 20 ml/kg of fluid can be administered within the initial 30-45 minutes. It was recommended to assess the adequacy of early fluid resuscitation every 4-6 hours, ensuring that the resuscitation objective could meet at least two of the following criteria: urine output of 0.5-1 ml·kg -1·h -1, mean arterial pressure of 65-85 mmHg, central venous pressure of 8-12 mmHg, heart rate below 120 beats/min, central venous oxygen saturation of at least 70%, and a decrease in hematocrit levels to 30%-35%. Conclusions:The most compelling evidence supporting the implementation of early fluid resuscitation management in patients with SAP is derived from an evidence-based nursing approach, which could effectively improve patient care outcomes.

Objective:To study the expression level and clinical significance of minichromosome maintenance protein 3(MCM3) in human gastric cancer.Methods:The expression levels of MCM3 mRNA and protein in gastric cancer and adjacent normal tissues were analyzed using public databases such as TCGA, CCLE and HPA. The clinicopathological features of 69 patients with gastric cancer were retrospectively analyzed, and the expression levels of MCM3 protein in tumor tissues and adjacent normal tissues were detected by immunohistochemical staining, and the relationship between it and clinicopathological features was analyzed. The interaction network of MCM3 proteins was analyzed using the STRING database.Results:The expression levels of MCM3 mRNA and protein in gastric cancer tissues were significantly higher than those in adjacent normal tissues ( P<0.05), and its high expression was correlated with the size of gastric cancer tumors ( P<0.05). In gastric cancer tissue, the expression of MCM3 was correlated with the expression level of proliferating cell nuclear antigen (PCNA) ( R=0.61, P<0.01), and there may be a protein-protein interaction. Conclusions:MCM3 plays an important role in gastric cancer by interacting with PCNA, and it is expected to become a new diagnostic and therapeutic target.

Background and objective Complete thoracoscopic segmentectomy gained great attention with the high detection rate of early lung cancer. Electrocautery and stapler are most commonly used in dividing the intersegmental plane in pulmonary segmentectomy. However, few reports comparing the two methods exist;all of which contrapose an open approach because complete thoracoscopic approach is not mentioned. hTe aim of this study is to evaluate and compare the safety and effcacy of the two methods in intersegmental plane dissection during complete thoracoscopic pulmonary segmen-tectomy. Methods A retrospective review of prospectively collected data was obtained for 58 consecutive patients who were treated by segmentectomy between September 2013 and March 2016 at a single center. hTe patients were divided into two groups according to the methods in intersegmental plane dissection. hTirty patients underwent intersegmental plane dissection with electrocautery (electrocautery group), and 28 patients underwent the same process using staplers (stapler group). Pre-operative, intraoperative, and postoperative variables for patients were compared between two groups. Results hTe operative time of electrocautery group was longer than that of the stapler group [(248.70±54.46) min vs (209.39±67.25) min, P=0.017]. Furthermore, no statistical difference was found between two groups in intraoperative blood loss (60.00 mL vs 65.00 mL), total drainage volume (445.00 mL vs 590.00 mL), drainage volume in ifrst 3 days atfer surgery [(455.33±318.333) mL vs (422.32± 194.95) mL], duration of chest tube drainage [(4.20±2.07) d vs (4.11±1.61) d], postoperative hospital stay [(6.33±2.98) d vs (5.89±1.55) d], and incidence of minor postoperative complication [16.7%(5/30) vs 7.1%(2/28)]. Conclusion Although operative time was longer in electrocautery group than in stapler group, using electrocautery for intersegmental plane dissec-tion in complete thoracoscopic segmentectomy appeared to be a very safe and feasible procedure compared with stapler.

Background Hexavalent chromium [Cr(VI)] exposure can cause structural disruption of intestinal flora and functional impairment. Vitamin C (VC) is one of the essential micronutrients, which plays an important role in promoting the growth of intestinal probiotics, improving the intestinal barrier, and maintaining the homeostasis of intestinal flora. However, the regulatory effect of VC on the intestinal flora disorders caused by Cr(VI) exposure remains to be investigated. Objective To investigate the effect of VC on intestinal flora disruption in mice due to Cr(VI) exposure. Methods Thirty-two SPF-grade C57BL/6 mice were acclimatized and fed for 3 d and randomly divided into control (Con), VC, potassium dichromate [K2Cr2O7, Cr(VI)], and VC+K2Cr2O7 [VC+Cr(VI)] groups. At 8:00 a.m. on day 4, the Con group (double-distilled water given by gavage and injected intraperitoneally), the VC group (VC given by gavage and double-distilled water injected intraperitoneally), the Cr(VI) group (double-distilled water given by gavage and K2Cr2O7 solution injected intraperitoneally), and the VC+Cr(VI) group (VC given by gavage and K2Cr2O7 solution injected intraperitoneally) were treated. The dose of VC was 200 mg·kg−1, and the dose of K2Cr2O7 was 1.25 mg·kg−1. The mice were treated for 45 consecutive days and then executed, the contents of the colon were sampled in sterile freezing tubes, and three replicates were collected from each group. After labeling, the samples were immediately put into liquid nitrogen for rapid freezing. After all the samples were collected, they were transferred to a -80 ℃ ultra-low temperature refrigerator for storage. Samples of colon contents were analyzed for intestinal flora structure by high-throughput sequencing and bioinformatics software. Results The Cr(VI) exposure resulted in reduced body weight gain values in mice compared to the Con group. Pathological changes occurred in the ileal tissue of mice, with significant inflammatory cell infiltration in the Cr(VI) group and reduced inflammatory cell infiltration in the VC+Cr(VI) group. The number of operational taxonomic units (OTUs) of intestinal flora was altered in the Cr(VI) group of mice. In the α diversity analysis, the mean Sobs index in the Cr(VI) group was 240.333±67.796, the Chao index was 258.173±64.813, and the Ace index was 259.481±66.891, which were significantly lower than those in the Con group (P<0.05), the PD whole tree index in the Cr(VI) group was 27.863±2.399, which was significantly higher than that in the Con group (P<0.05), and the VC intervention significantly reversed the changes of the above indexes due to Cr(VI) exposure (P<0.05). In the β diversity analysis, the principal coordinates analysis (PCoA) results showed a significant separation between the Cr(VI) group and the Con group, and after the VC intervention, there was a retraction of the separation trend and the difference was reduced. The multi-sample similarity dendrogram results showed that the control and the VC groups clustered together first, then with the VC+Cr(VI) group, and finally with the Cr(VI) group. The abundances of Bacteroidetes, Saccharibacteria, and Tenericutes in the intestine of mice in the Cr(VI) group were decreased, and the abundance of Firmicutes was increased; the abundances of Lactobacillus, Alistipes, Bacteroides, and Ruminiclostridium were also increased. Included among these, Bacteroides showed a significantly higher abundance compared to the control mice (P<0.05). Changes in the abundances of phyla and genera of the above mentioned gut microorganisms were reversed after the VC intervention. Conclusion Cr(VI) exposure can lead to intestinal damage and disorganization of the intestinal flora structure in mice, while VC intervention can ameliorate the above changes to a certain extent and normalize the intestinal flora structure.
