ABSTRACT
Objective To explore the active components of Jianpi Xiaoai Prescription and its mechanism in the treatment of colorectal cancer(CRC).Methods UPLC-Q-TOF-MS technology was used to identify the chemical components of Jianpi Xiaoai Prescription;Active components and target proteins were screened through TCMSP and SwissTargetPrediction databases;STRING database was used for protein interaction analysis;The GeneCards database was used to screen CRC-related targets;DAVID database was used for GO and KEGG pathway enrichment analysis;Molecular docking verification of main active components and key targets was conducted.A rat model of CRC was constructed,and the effect of Jianpi Xiaoai Prescription on key targets of CRC-related pathways in rats was verified by Western blot.Results Totally 35 active components of Jianpi Xiaoai Prescription,617 potential targets,and 325 intersected with CRC-related targets were obtained.The enrichment analysis of active component targets showed that the main enrichments were PI3K-Akt signaling pathway,EGFR tyrosine kinase inhibitors signaling pathway,T cell receptor signaling pathway,VEGF signaling pathway and other related pathways.13 key active components and 6 key proteins of EGFR,SRC,CA2,CA12,CYP19A1 and MAPK3 were obtained in Jianpi Xiaoai Prescription.The results of Western blot experiments showed that Jianpi Xiaoai Prescription could significantly reduce the protein expression levels of SRC and EGFR in rat CRC samples.Conclusion The active component in Jianpi Xiaoai Prescription may exert anti CRC cell proliferation,invasion,and metastasis effects by regulating EGFR,SRC with multiple targets and pathways.
ABSTRACT
High-risk human papillomavirus (HPV)-related cancers consist of cervical cancer, anal cancer, penile cancer, vulvar cancer, vaginal cancer, and head and neck cancer (HNC). Of these, the disease burden of HNC is second only to cervical cancer. HNC mostly originates from malignant lesions of squamous epithelial cells and mainly includes oral cavity cancer, pharyngeal cancer (including nasopharyngeal cancer, oropharyngeal cancer, and hypopharyngeal cancer), and laryngeal cancer. Tobacco use, alcohol abuse, and HPV infection are three primary risk factors. Recently, there is an upward trend of HNC incidence globally, especially in high-income countries. In China, the disease burden and trends of HPV-related HNC are still not clear. A few small sample size and single-center studies suggest a high HPV prevalence and increasing trend in HNC. Methodological differences in HPV testing and regional variabilities still exist among these studies. Among the anatomic sites, oropharyngeal cancer has been shown to be caused by HPV infection, but the association of HPV with other sites is still under debate. In addition, there is a paucity of relevant studies. Here, this review narrates the association between HPV infection and HNC, compares the differences between global and Chinese studies, and then explores the importance of HPV infection in various anatomical sites. The main objective is to highlight the research on HPV-related HNC and promote relevant prevention and treatment programs.

Objective: This cross-sectional investigation aimed to determine the incidence, clinical characteristics, prognosis, and related risk factors of olfactory and gustatory dysfunctions related to infection with the SARS-CoV-2 Omicron strain in mainland China. Methods: Data of patients with SARS-CoV-2 from December 28, 2022, to February 21, 2023, were collected through online and offline questionnaires from 45 tertiary hospitals and one center for disease control and prevention in mainland China. The questionnaire included demographic information, previous health history, smoking and alcohol drinking, SARS-CoV-2 vaccination, olfactory and gustatory function before and after infection, other symptoms after infection, as well as the duration and improvement of olfactory and gustatory dysfunction. The self-reported olfactory and gustatory functions of patients were evaluated using the Olfactory VAS scale and Gustatory VAS scale. Results: A total of 35 566 valid questionnaires were obtained, revealing a high incidence of olfactory and taste dysfunctions related to infection with the SARS-CoV-2 Omicron strain (67.75%). Females(χ2=367.013, P<0.001) and young people(χ2=120.210, P<0.001) were more likely to develop these dysfunctions. Gender(OR=1.564, 95%CI: 1.487-1.645), SARS-CoV-2 vaccination status (OR=1.334, 95%CI: 1.164-1.530), oral health status (OR=0.881, 95%CI: 0.839-0.926), smoking history (OR=1.152, 95%CI=1.080-1.229), and drinking history (OR=0.854, 95%CI: 0.785-0.928) were correlated with the occurrence of olfactory and taste dysfunctions related to SARS-CoV-2(above P<0.001). 44.62% (4 391/9 840) of the patients who had not recovered their sense of smell and taste also suffered from nasal congestion, runny nose, and 32.62% (3 210/9 840) suffered from dry mouth and sore throat. The improvement of olfactory and taste functions was correlated with the persistence of accompanying symptoms(χ2=10.873, P=0.001). The average score of olfactory and taste VAS scale was 8.41 and 8.51 respectively before SARS-CoV-2 infection, but decreased to3.69 and 4.29 respectively after SARS-CoV-2 infection, and recovered to 5.83and 6.55 respectively at the time of the survey. The median duration of olfactory and gustatory dysfunctions was 15 days and 12 days, respectively, with 0.5% (121/24 096) of patients experiencing these dysfunctions for more than 28 days. The overall self-reported improvement rate of smell and taste dysfunctions was 59.16% (14 256/24 096). Gender(OR=0.893, 95%CI: 0.839-0.951), SARS-CoV-2 vaccination status (OR=1.334, 95%CI: 1.164-1.530), history of head and facial trauma(OR=1.180, 95%CI: 1.036-1.344, P=0.013), nose (OR=1.104, 95%CI: 1.042-1.171, P=0.001) and oral (OR=1.162, 95%CI: 1.096-1.233) health status, smoking history(OR=0.765, 95%CI: 0.709-0.825), and the persistence of accompanying symptoms (OR=0.359, 95%CI: 0.332-0.388) were correlated with the recovery of olfactory and taste dysfunctions related to SARS-CoV-2 (above P<0.001 except for the indicated values). Conclusion: The incidence of olfactory and taste dysfunctions related to infection with the SARS-CoV-2 Omicron strain is high in mainland China, with females and young people more likely to develop these dysfunctions. Active and effective intervention measures may be required for cases that persist for a long time. The recovery of olfactory and taste functions is influenced by several factors, including gender, SARS-CoV-2 vaccination status, history of head and facial trauma, nasal and oral health status, smoking history, and persistence of accompanying symptoms.

Objective To compare the differences in pathogenicity and gene expression profiles between adult Schistosoma japonicum isolated from hilly and marshland and lake regions of Anhui Province, so as to provide the scientific evidence for formulating the precise schistosomiasis control strategy in different endemic foci. Methods C57BL/6 mice were infected with cercariae of S. japonicum isolates from Shitai County (hilly regions) and Susong County (marshland and lake regions) of Anhui Province in 2021, and all mice were sacrificed 44 days post-infection and dissected. The worm burdens, number of S. japonicum eggs deposited in the liver, and the area of egg granulomas in the liver were measured to compare the difference in the pathogenicity between the two isolates. In addition, female and male adult S. japonicum worms were collected and subjected to transcriptome sequencing, and the gene expression profiles were compared between Shitai and Susong isolates of S. japonicum. The differentially expressed genes (DEGs) were subjected to Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses. Results The total worm burdens [(14.50 ± 3.96) worms/mouse vs. (16.10 ± 3.78) worms/mouse; t = 0.877, P = 0.392], number of female and male paired worms [(4.50 ± 0.67) worms/mouse vs. (5.10 ± 1.45) worms/mouse; t = 1.129, P = 0.280], number of unpaired male worms [(5.50 ± 4.01) worms/mouse vs. (5.60 ± 1.69) worms/mouse; t = 0.069, P = 0.946], number of eggs deposited in per gram liver [(12 116.70 ± 6 508.83) eggs vs. (16 696.70 ± 4 571.56) eggs; t = 1.821, P = 0.085], and area of a single egg granuloma in the liver [(74 359.40 ± 11 766.34) µm2 vs. (74 836.90 ± 13 086.12) µm2; t = 0.081, P = 0.936] were comparable between Shitai and Susong isolates of S. japonicum. Transcriptome sequencing identified 584 DEGs between adult female worms and 1 598 DEGs between adult male worms of Shitai and Susong isolates of S. japonicum. GO enrichment analysis showed that the DEGs between female adults were predominantly enriched in biological processes of stimulus response, cytotoxicity, multiple cell biological processes, metabolic processes, cellular processes and signaling pathways, cellular components of cell, organelles and cell membranes and molecular functions of binding and catalytic ability, and KEGG enrichment analysis showed that these DEGs were significantly enriched in pathways of vascular endothelial growth factor signaling, glutathione metabolism, arginine and proline metabolism. In addition, the DEGs between male adults were predominantly enriched in biological processes of signaling transduction, multiple cell biological processes, regulation of biological processes, metabolic processes, development processes and stimulus responses, cellular components of extracellular matrix and cell junction and molecular functions of binding and catalytic ability, and these DEGs were significantly enriched in pathways of Wnt signaling, Ras signaling, natural killer cells-mediated cytotoxicity, extracellular matrix-receptor interactions and arginine biosynthesis. Conclusions There is no significant difference in the pathogenicity between S. japonicum isolates from hilly and marshland and lake regions of Anhui Province; however, the gene expression profiles vary significantly between S. japonicum isolates.
ABSTRACT
Objective: To explore the application value of enhanced recovery after surgery (ERAS) with the multidisciplinary team (MDT) model in laryngeal cancer surgery. Methods: Eighty patients with laryngeal cancer treated in Department of Otorhinolaryngology Head and Neck Surgery of Yantai Yuhuangding Hospital from May 2016 to June 2017 were selected, including 76 males and 4 females, aged 45 to 75 years old. By random number table method, they were divided into ERAS group (40 cases) and control group (40 cases). Visual analogue scale (VAS), general comfort questionnaire (GCQ) and self-rating Anxiety Scale (SAS) were used to evaluate the symptoms and signs and psychological state of the two groups before and after operation. Mann Whitney U test was used for non-normal distribution data, and chi square test, Fisher exact probability method and covariance analysis were used for classification data. Repeated measures analysis of variance was used for the comparison of each group at different time points. Results: Two cases in the ERAS group and six cases in the control group withdrew from the study for some reason. Finally, 38 cases in the ERAS group and 34 cases in the control group were enrolled in this study. The postoperative pain scores of the two groups were the highest at 6 h after operation, and then gradually decreased. At different time points after operation, the pain scores of ERAS group were lower than those of the control group. At 24 h after operation, the pain relief degree of ERAS group was significantly higher than that of the control group, with a statistically significant difference (P<0.05). Compared to control group, ERAS group had lower preoperative thirst score [(0.15±0.36) vs. (4.29±1.17), Z=-7.695, P<0.001] and hunger score [(0.38±0.49) vs. (3.44±1.13), Z=-7.426, P<0.001]. The total number of postoperative adverse reactions (8 vs.16), oral feeding time [(4.06±4.42) d vs. (9.06±2.42) d] and postoperative hospital stay [(5.91±0.97) d vs. (11.03±2.11)d] in ERAS group were lower than those in control group (statistics 5.461, -4.558, -7.347, P<0.05), but there was no significant difference in postoperative catheter indwelling time and neck drainage tube indwelling time between the two groups (P>0.05). Before discharge, the comfort of ERAS group was significantly higher than that of control group [(60.37±8.78) vs. (50.38±8.08), Z=-4.370, P<0.001]. Before discharge, the anxiety level of ERAS group decreased, while that of the control group increased significantly, which was higher than that of ERAS Group [(59.12±6.43) vs. (52.62±6.25), Z=-4.179, P<0.001]. Conclusion: The application of multidisciplinary ERAS in laryngeal cancer surgery can improve preoperative hunger and thirst, postoperative pain and mental state, shorten the length of hospital stay and reduce postoperative adverse reactions.

Objective: To explore the effect of perioperative airway management based on the concept of enhanced recovery after surgery (ERAS) on the improvement of preoperative pulmonary function in patients with aspirin intolerance triad (AIT). Methods: Thirty patients with AIT (including 13 males and 17 females, aged from 29 to 75 years old) for sinus surgery from January 2018 to December 2019 were selected, 172 patients (including 105 males and 67 females, aged from 17 to 83 years old) with chronic rhinosinusitis with nasal polyps (CRSwNP) without lower airway disease were selected by random number table at the same period, and their clinical data and preoperative pulmonary function were analyzed and compared retrospectively. FEV1%pred<80% after bronchodilation test was considered as high risk for surgery. Preoperative evaluation and standardized drug intervention were applied in patients with pulmonary function abnormalities at risk for surgery, and improvement of preoperative pulmonary function and tolerability to general anesthesia surgery in the two groups were evaluated. All the statistical analyses were conducted using SPSS 22.0. Results: The main pulmonary function indexes (FEV1%pred, FEV1/FVC%pred, FEF50%pred, FEF75%pred, MMEF%pred) in AIT group decreased significantly than those in CRSwNP group (t values were 10.882, 10.506, 9.141, 10.182, 9.099, respectively, all P<0.001). At admission 86.7% (26/30) patients in the AIT group and 11.6% (20/172) patients in CRSwNP group had high surgical risk for lung function, with significantly difference (χ2 = 81.788, P<0.05); after 3 days with individualized drug intervention, 57.7% (15/26) patients in AIT group reached the standard for surgery, which was significantly less than 90.0% (18/20) patients in CRSwNP group (χ²=4.335,P<0.05); and after 6 days with drug intervention, the patients who reached the standard for surgery in pulmonary function accounted for 92.3% (24/26) in the AIT group and 100% (20/20) in the CRSwNP group. FEV1%pred in the two groups before surgery were significantly improved compared with those at admission respectively ((90.00±6.32)% vs. (64.79±13.60)%,t value was 10.110 in AIT group; (91.65±11.86)% vs. (76.40±9.35)%, t value was 9.346 in CRSwNP group; all P<0.05), and also FEV1/FVC%pred, FEF50%pred, FEF75%pred and MMEF%pred were all significantly improved (all P<0.05). Surgery was completed successfully in the two groups of patients with lung function meeting the surgical standard, and no intraoperative or postoperative airway adverse events occurred. Conclusion: AIT patients have high airway risk for sinus surgery due to poor pulmonary function. Standardized airway management based on the concept of ERAS can improve the pulmonary function of patients, and decrease the incidence of perioperative airway adverse events.

BACKGROUND: Blood oxygenation level dependent functional MRI (BOLD-fMRI) has proven to be a powerful tool for studying the functional change of the brain. In task-state fMRI study, the functional reorganization of sensory and motor cortex has been observed in patients with cervical spondylotic myelopathy. OBJECTIVE: To discuss the correlations between task-state fMRI measurements with clinical symptoms and surgical outcomes of cervical spondylotic myelopathy. METHODS: Eighty-two patients with cervical spondylotic myelopathy undergoing posterior cervical decompression (cervical spondylotic myelopathy group) and forty-five healthy volunteers (normal group) were recruited from January 2018 to January 2019. All subjects underwent fMRI and performed a finger-tapping paradigm with the right hand. The Japanese Orthopaedic Association score was used to evaluate the function of the spinal cord. Japanese Orthopaedic Association score recovery rate less than 50% was defined as a poor result. RESULTS AND CONCLUSION: (1) Japanese Orthopaedic Association score was significantly improved after surgery in the cervical spondylotic myelopathy group compared with that before surgery (P 0.05). Before surgery, VOA ratio (left precentral gyrus/left postcentral gyrus) was significantly higher in the cervical spondylotic myelopathy group than in normal group (P 0.05). VOA ratio was significantly decreased compared with that preoperatively (P < 0.05). (4) Correlation analysis revealed that the VOA in the left precentral gyrus and left postcentral gyrus and VOA ratio were significantly correlated with preoperative Japanese Orthopaedic Association score and postoperative Japanese Orthopaedic Association score recovery rate (P < 0.05). The absolute value of correlation coefficient of VOA ratio with preoperative Japanese Orthopaedic Association score and postoperative recovery rate was largest. (5) Receiver operating characteristic curve analysis showed that the area under the curve value for the VOA ratio was 0.803, indicating strong predictive discrimination, and the cut-off value was 3.621. The area under the curve value for Japanese Orthopaedic Association score was 0.751, and the cut-off value was 8. The predictive effect of VOA ratio was higher than Japanese Orthopaedic Association score. (6) The results indicate that the VOA in the left precentral gyrus and left postcentral gyrus was negatively correlated with severity of clinical symptoms (Japanese Orthopaedic Association score). Preoperative VOA ratio can effectively predict the recovery of spinal cord function after operation in patients with cervical spondylotic myelopathy.
ABSTRACT
Objective To characterize the epidermal growth factor receptor (EGFR) gene in Schistosoma japonicum (SjEGFR gene) and investigate the role of the EGFR gene in regulating the growth, reproductive system, maturation and fecundity of S. japonicum. Methods Rapid amplification of cDNA ends (RACE) was performed to obtain the full length of the SjEGFR gene, and the SjEGFR gene expression was quantified in different developmental stages of S. japonicum using a quantitative real-time PCR (qPCR) assay. The tissue localization of the SjEGFR gene was detected in 22-day parasite using whole-mount in situ hybridization (WISH). Following RNA interference (RNAi)-induced knockdown of the SjEGFR gene, the worm length, pairing rate and worm burden of S. japonicum were measured, and the worm morphology was observed using optical microscopy and confocal microscopy. Results The SjEGFR gene was identified with a conserved tyrosine-kinase active site, and the SjEGFR gene expression was detected at various developmental stages in male and female parasites. WISH showed that the transcript of the SjEGFR gene was localized on the tegument and in the digestive organs of S. japonicum. RNAi-induced SjEGFR knockdown resulted in marked suppression of the worm growth, smaller size of male testicles that contained more immature spermatocytes, and apparent impairment of ovary and vitelline gland development. In addition, no eggs were found in the uterus of SjEGFR knocked-down female parasites, indicating the interruption of egg production. Conclusions Inhibition of SjEGFR expression may remarkably suppress the growth and maturation of S. japonicum, and interrupt the egg production.
ABSTRACT
Objective:To explore the correlation between different smoking status and serum uric acid(SUA)in a middle-aged male in health check-up population.Methods:In this cross-sectional study, a total of 26701 middle-aged men who underwent health check-up in Taihu Sanatorium of Jiangsu Province from January 2014 to June 2015 were studied.The correlation between smoking status and SUA was analyzed by questionnaires, physical examination and serum biochemical assay.Smoking state was divided into no smoking, a occasional smoking and smoking groups.Results:With the increase of age, there was a downward trend of SUA( F=7.38, P=0.000). Among the three smoking groups, the group with occasional smoking had the highest level of SUA.The smoking group had lower level of SUA than the non-smoking group and occasional smoking group( P=0.000 and 0.005). In the non-smoking group, the fourth quartile of SUA(41.5%)had a higher percentage than that in first quartile of SUA(38.4%)( χ2=12.266, P=0.000). In the smoking group, the fourth quartile of SUA(54.9%)had lower percentage than that in the first quartile of SUA(58.4%)( χ2=7.049, P=0.008). Compared with the non-smoking group, the prevalence of hyperuricemia(HUA)in smoking group was lower( OR=0.872, 95% CI: 0.821~0.927, P=0.000), the prevalence of HUA in occasional smoking group was higher( OR=1.194, 95% CI: 1.013~1.408, P=0.035). Conclusions:As compared with the non-smoking group, the prevalence of HUA is lower in smoking group and is higher in occasional smoking group.
ABSTRACT
OBJECTIVE We used Al lergic Rhinitis Control Test (ARCT) questionnaire to evaluate the control level of allergic rhinitis, in order to get the data of prevalence rate, epidemiological characters and risk factors of uncontrolled allergic rhinitis. METHODS Patients with AR were recruited from our department and the treatment based on the Allergic Rhinitis and Its Impact on Asthma(ARIA) guidelines. Telephone interview will be taken after 2 weeks in these patients, compared to symptoms, impact on quality of life, ARCT value before and after treatment. RESULTS Among 134 patients enrolled, moderate/severe AR account for 95%. After 2 weeks of treatment, both symptom and quality of life were marked improvement(P <0.001). Patients with uncontrolled AR(26.1%) at day 15 more frequently presented higher height and weight(P <0.001), history of ear, nose, and throat(ENT) infection or antibiotics intake for respiratory infection in the last 12 months (40.4% versus 62.9%, P =0.022), smoking (4.0% versus 17.1%, P =0.02), and smell disturbance (10.1% versus 25.7%, P =0.044). CONCLUSION Most of AR patients have remarkable improvements in symptom and quality of life after treatment, but 26.1% of patients still remain uncontrolled. Smoking and nose infection are risk factors of uncontrolled AR.

ABSTRACT
Adolescent is a special group which is still at the period of growth and development. Protecting reproductive function, reducing recurrence and chronic postoperative inguinal pain are the key points of treatment of inguinal hernia in adolescents. Although there are different surgical treatments for inguinal hernia in adolescents at present, the characteristics of biological mesh which can promote tissue regeneration and remodeling make them valuable for inguinal hernia repair in adolescents. Correct selection and implementation of biological mesh inguinal hernia repair are important to ensure the effect of adolescent inguinal hernia repair.
ABSTRACT
There is still debate regarding the optimal surgical approach for proximal hypospadias. This retrospective study aims to evaluate the long-term outcomes using transverse preputial island flap urethroplasty. A total of 320 patients were included, with a mean follow-up of 40.2 months (range: 1-156 months). Complications were encountered in 125 patients (39.1%), including fistulas in 53 (16.6%), urethral strictures in 31 (9.7%), and diverticula in 41 (12.8%). The mean timing of presentation with a complication was 15.8 months (median: 1.7, range: 1-145), of which 79.2% were early complications and 20.8% were late complications. In all, 20.8% of the patients with complications presented after ≥1 year, and 12.8% presented after ≥5 years. Univariate analysis revealed that age at the time of surgery, flap length, and location of the urethral meatus were not correlated with complications. A stricture was present in 31.7% (13/41) of those with diverticula (P < 0.001), while late urethral diverticula were accompanied by urethral strictures in 11.1% (1/9) of cases (P = 0.213). These results indicate that transverse preputial island flap urethroplasty still has a high incidence of complications, even when performed by highly experienced physicians. Most complications of hypospadias are diagnosed within 1 year postoperatively, while fistulas and urinary strictures generally occur within 2 months and diverticula tend to be present by 1 year.

Objective To explore the effect of methylprednisolone (MP) with different durations on pulmonary fibrosis in rats with acute lung injury induced by smoke inhalation. Methods A total of 178 male SD rats were randomized into 5 groups: control group (n=18), simple smoke inhalation group (smoke group, n=40), smoke inhalation+ MP treatment for 1 d, 3 d and 7 d groups, naming smoke+MP (1D) group (n=40), smoke+MP (3D) group (n=40) and smoke+MP (7D) group (n=40), respectively. The rats were exposed to smoke for 30 min in the smoke box to meet the criteria of acute lung injury. MP (4 mg/kg per day) was injected intraperitoneally at 1 d, 1-3 d and 1-7 d after smoke inhalation. Survival rates were calculated at 28 d after smoke inhalation. At 7 d, 14 d and 28 d after smoke inhalation, the lung tissues were stained with Masson’s trichrome staining and Sirius Red staining to evaluate pulmonary fibrosis. The mRNA expression levels of transforming growth factor β1 (TGF-β1) and α-smooth muscle actin (α-SMA) were detected by real-time fluorescent quantitative PCR, and the expression levels of myeloperoxidase (MPO), connective tissue growth factor (CTGF), high mobility group box 1 (HMGB1) and interleukin 6 (IL-6) were detected by Western blotting. Results The survival rate of the rats in the smoke group was 47.50%, and the survival rates were significantly improved to more than 80% after MP treatment with different durations (all P0.01). Masson’s trichrome staining and Sirius Red staining staining showed that the lung fibrosis of the rats in the smoke group was aggravated, and the fibrosis and collagen deposition in the smoke+MP (3D) and smoke+ MP (7D) groups were significantly attenuated compared with the smoke and smoke+MP (1D) groups (P0.05 or P0.01). As time progressed, the mRNA expression levels of TGF-β1 and α-SMA after smoke inhalation were increased in the smoke and smoke+MP (1D) groups. At 28 d after smoke inhalation, the TGF-β1 and α-SMA mRNA levels were significantly higher in the smoke and smoke+MP (1D) groups compared with the smoke+MP (3D) and smoke+MP (7D) groups (P0.05 or P0.01). At 28 d after smoke inhalation, the protein expression levels of MPO, CTGF, HMGB1 and IL-6 were significantly reduced in smoke+MP (3D) and smoke+MP (7D) groups compared with the smoke and smoke+MP (1D) groups (P0.05, P0.01). However, the above indicators have no significant difference between smoke+MP (3D) group and smoke+MP (7D) group (all P0.05). Conclusion MP can significantly improve survival rate of rats with smoke inhalation injury. MP treatment for 3 d or 7 d can significantly attenuate smoke inhalation induced pulmonary fibrosis at 28 d after smoke inhalation, but there is no significant difference between these two treatment protocols.

ABSTRACT
Objective To investigate whether continuous intravenous intraoperative lidocaine infusion can reduce the opioids dosage and improve postoperative recovery in patients undergoing video-assisted thoracoscopic(VATS) lobectomy. Methods Totally 60 patients undergoing VATS lobectomy were enrolled in this single-center randomized controlled study.The patients were equally randomized into lidocaine continuous pumping group(lidocaine group) and control group by computer-based random numbers.The patients had double-lumen catheter intubation,and total intravenous anesthesia was administrated intraoperatively.In the lidocaine group,patients continuously received intravenous pumping of lidocaine [2 mg/(kgdh) ] after a loading doses(1 mg/kg) until the end of the operation.We recorded the basic characteristics,preoperative examination,intraoperative medications,and postoperative recovery of both groups.Results The basic characteristics and preoperative examination findings were comparable between these two groups(all P>0.05).Compared with the control group,the intraoperative sufentanil consumption significantly decreased in the lidocaine group [(32.3±7.5) μg vs.(40.9±10.2) μg,P<0.001].Significantly more patients were given esmolol intraoperatively in the control group to lower heart rate(P=0.010).The incidence of postoperative nausea within 24 hours was significantly lower in the lidocaine group(P=0.045).There was no significant difference between the two groups in postoperative recovery(all P>0.05).Conclusion Intravenous continuous pumping of lidocaine during operation can reduce opioids consumption and lower the incidence of postoperative nausea without extra adverse or toxic reaction in patients undergoing VATS lobectomy.
ABSTRACT
Objective To explore the effect of the combination of carnitine palmityl transferase 1( CPT1) inhibitor etomoxir and chemotherapy drug cisplatin on lung cancer cell line A549 proliferation and migration of lung cancer. Methods CCK8 was applied to investigate the effect of the combination of etomoxir and cisplatin on A549 survival. Transwell test was used to detect migration of lung cancer cell line A549 treated with the combination of etomoxir and cisplatin. Apoptosis of A549 was detected by annexin V/PI. A549 transplanted mice were used to test therapeu-tic effect of etomoxir combined with cisplatin. Results Tumor cells proliferation and migration were inhibited by the combination of etomoxir and cisplatin. Apoptosis of tumor cells was enhanced by the combination of etomoxir. After the treatment of the combination of etomoxir and cisplatin, tumor growth of mouse was inhibited. Conclusions The combination of etomoxir and cisplatin can decrease tumor cells survival and induce tumor cells apoptosis, and then inhibit tumor growth in mouse lung cancer model.
ABSTRACT
Parkinson disease (PD) is a neurodegenerative disorder resulting from alpha-synuclein lesions, which affects about eight million patients over the world. PD is manifested in progressive motor and non-motor symptoms. With understanding of PD gradually deepened, motor symptoms mainly manifested in resting tremor are not the only manifestations of PD. Clinically many non-motor symptoms such as autonomic nervous symptoms, mental symptoms and paresthesia are also the important manifestations of PD and can appear earlier than motor symptoms. The effect of the non-motor symptoms on the patients' life is often not less than that of the motor symptoms. Clinically the changeable non-motor symptoms are far more complex and more difficult to treat than the motor symptoms. Conventional anti-PD drugs such as levodopa have little effect on the non-motor symptoms. Present clinical studies have showed that acupuncture has a certain therapeutic effect on the non-motor symptoms of PD. This provides important help for expanding the way to treat PD.
ABSTRACT
To investigate the effect and mechanism of miR-498 on Th17 cell differentiation of peripheral blood mononuclear cells (PMBCs) in rheumatoid arthritis (RA) patients, peripheral blood samples were collected from RA patients and healthy controls, respectively. The proportion of CD4IL-17 T cells (Th17 cells) or CD4FOXP3 T cells (Tregs) in T cells and the Th17/Treg ratio were identified by the flow cytometer. The STAT3 and miR-498 expression were measured by Western blot and real-time PCR, respectively. ELISA was used to detect IL-17 concentrations. Luciferase assay was performed to confirm that miR-498 directly targeted the 3' untranslated region (3'UTR) of STAT3 in CD4 T cells. The effect of miR-498 on Th17 cell differentiation was explored by transfection of miR-498 mimic and/or pcDNA-STAT3 into CD4 T cells. In PMBCs of RA patients, the Th17/CD4 T cell ratio was significantly increased, while the Tregs/CD4 T cell ratio was obviously decreased, leading to a higher Th17/Treg ratio. The results showed a reduced miR-498 expression and an increased STAT3 protein expression in PMBCs, and an increased IL-17 concentration in serum of RA patients. In cells transfected with wild-type-STAT3-LU, miR-498 mimic significantly reduced the luciferase activity, STAT3 gene and protein expression, and miR-498 inhibitor had an opposite function. While the miR-498 mimic/inhibitor had no effect on the luciferase activity and STAT3 expression in cells transfected with mutant-STAT3-LU. CD4 T cells transfected with miR-498 mimic had a lower Th17/CD4 T cell ratio and IL-17 concentration, however, transfection of pcDNA-STAT3 reversed the effect of miR-498 mimic on Th17/CD4 T cell ratio and IL-17 concentration. These results suggest that overexpression of miR-498 suppresses Th17 cell differentiation by targeting STAT3 in RA patients.
