ObjectiveTo evaluate the clinical effectiveness and safety of acupuncture with manipulation for lumbar disc herniation in remission period. MethodsOne hundred and four patients with lumbar disc herniation in remission were randomly divided into a treatment group and a control group， with 52 cases in each group. Treatment group applied acupuncture with manipulation of pointing， pulling， and shaking. Acupoints were selected as lumbar Jiaji （EX-B2， bilateral）， Ashi point， Shenshu （BL 23， bilateral）， Huantiao （GB 30， bilateral）， Weizhong （BL 40， opposite side of the affected area）， Chengshan （BL 57， opposite side of the affected area）. The control group applied lumbar traction plus acupoint ultrasonic pulse penetration therapy （acupoints selection same as the treatment group）； 20 minutes each time， 3 times a week， a total of 3 weeks for both groups. The primary outcome was the improvement rate of lumbar disc herniation symptoms and signs， which was calculated at 1 week of treatment， 3 weeks of treatment， 1 month follow-up， and 3 months follow-up， respectively； the secondary outcome were the Japanese Orthopaedic Association （JOA） scores， Visual Analogue Scale （VAS） scores， and Oswestry Disability Index （ODI） scores （including ODI total scores， sitting scores and standing scores）， which were evaluated before treatment， 1 week of treatment， 3 weeks of treatment， 1 month follow-up， and 3 months follow-up； clinical effectiveness was assessed at 3 months follow-up； and the occurrence of adverse events in the participants， as well as blood routine， urine routine， stool routine， and electrocardiograms before and after the treatment were recorded to evaluate safety. ResultsTwo patients from each group fell out， and 50 patients of each group were included in the outcome analysis ultimately. The scores of lumbar disc herniation symptoms and signs improved more in the treatment group than in the control group at 1 week of treatment， 3 weeks of treatment， 1 month follow-up and 3 months follow-up （P＜0.01）. The JOA scores of participants in both groups at 1 week of treatment， 3 weeks of treatment， 1 month follow-up and 3 months follow-up were higher than those before treatment in the same group， and the VAS scores， ODI total scores， ODI sitting scores and standing scores were significantly lower than those before treatment in the same group （P＜0.05）， and the JOA scores of patients in the treatment group were higher than those of the control group at all time points， and the VAS scores， ODI total scores， ODI sitting scores and standing score were lower than those of the control group （P＜0.05）. At the 3 months follow-up， the excellent rate of the treatment group was 70.00% （35/50） better than that of the control group， which was 50.00% （25/50） （P＜0.05）. There were no abnormalities in blood， urine， stool routines and electrocardiograms before and after treatment in both groups， and no adverse events occurred. ConclusionAcupuncture with manipulation of pointing， pulling， and shaking for treating patients with lumbar disc herniation in remission has a better safety on pain relief and improving quality of life， and the effectiveness is better than lumbar traction plus acupoint ultrasonic pulse penetration therapy.

Objective To monitor and evaluate the synergistic antitumor effects of programmed death-1(PD-1)checkpoint inhibitor combined with radiation therapy through whole-body dynamic 18 F-Fluorodeoxy glucose positron emission computed tomography(18F-FDG PET/CT)and Patlak multi-parametric analysis.Methods B16F10 mel-anoma dual-tumor mouse model was established and randomly divided into control,PD-1 monoclonal antibody,ra-diation-only,and combination groups(n=6).Whole-body 18F-FDG PET/CT imaging was performed before and 24 hours post-treatment.The changes of maximum standardized uptake value(SUVmax)and metabolic rate of FDG(MRFDG)changes were analyzed and compared.Mice were then euthanized,tumors excised and underwent histo-pathology with HE,CD8,Ki-67 staining to assess immune infiltration and proliferation.Distal tumor volumes were monitored during treatment.Results At 24 hours post-treatment,in the primary tumors,SUVmax and MRFDG values increased compared to pre-treatment in the control group(P＜0.000 1),while they decreased in the combination treatment group(P＜0.000 1),with statistically significant differences.In the distal tumors,SUVmax and MRFDG values increased compared to pre-treatment in the control group,PD-1 monoclonal antibody group,and radiothera-py-alone group.The SUVmax differences were statistically significant in the control group before and after treatment(P＜0.000 1).MRFDG values in the distal tumors showed statistically significant differences in all three groups(P＜0.01 or P＜0.000 1).In the combination treatment group,SUVmax and MRFDG values in the distal tumors de-creased significantly compared to pre-treatment(P＜0.000 1).Post-treatment comparison of SUVmax and MRFDG values in the distal tumors showed that statistically significant differences in SUVmax and MRFDG values were observed among all groups except between the radiotherapy-alone and PD-1 monoclonal antibody groups(all P＜0.05).Im-munohistochemistry results showed that the mean absorbance value of CD8 T lymphocytes in the distal tumor was significantly higher than that in the other three groups(P＜0.001);the mean absorbance value of Ki-67 immuno-histochemistry in the distal tumor proliferation index was significantly lower than that in the other three groups(P＜0.001).Conclusion The synergistic effects of combined treatment reduced distal tumor growth.Whole-body 18F-FDG PET/CT Patlak multi-parametric imaging can monitor the synergistic effects of PD-1 antibody and radiotherapy in B16F10 melanoma,providing reliable imaging parameters for optimizing combinatorial therapies.

Objective:To explore the risk factors of insomnia among employees in the thermal power generation industry and the network relationships between their interactions, and to provide scientific basis for personalized interventions for high-risk groups with insomnia.Methods:In November 2022, 860 employees of a typical thermal power generation enterprise were selected as the research subjects by cluster sampling. On-site occupational health field surveys and questionnaire surveys were used to collect basic information, occupational characteristics, anxiety, depression, stress, occupational stress, and insomnia. The interaction between insomnia and occupational health psychological factors was evaluated by using structural equation model analysis and Bayesian network construction.Results:The detection rates of anxiety, depression and stress were 34.0% (292/860), 32.1% (276/860) and 18.0% (155/860), respectively. The total score of occupational stress was (445.3±49.9) points, and 160 workers (18.6%) were suspected of insomnia, and 578 workers (67.2%) had insomnia. Structural equation model analysis showed that occupational stress had a significant effect on the occurrence of insomnia in thermal power generation workers (standardized load coefficient was 0.644), and occupational health psychology had a low effect on insomnia (standardized load coefficient was 0.065). However, the Bayesian network model further analysis found that anxiety and stress were the two parent nodes of insomnia, with direct causal relationships, the arc strength was-8.607 and -15.665, respectively. The model prediction results showed that the probability of insomnia occurring was predicted to be 0 in the cases of no stress and anxiety, low stress without anxiety, and no stress with low anxiety. When high stress with low anxiety and low stress with high anxiety occurred, the predicted probability of insomnia occurring were 0.38 and 0.47, respectively. When both high stress and high anxiety occurred simultaneously, the predicted probability of insomnia occurring was 0.51.Conclusion:Bayesian network risk assessment can intuitively reveal and predict the insomnia risk of thermal power generation workers and the network interaction relationship between the risks. Anxiety and stress are the direct causal risks of insomnia, and stress is the main risk of individual insomnia of thermal power generation workers. The occurrence of insomnia can be reduced based on scientific intervention of stress conditions.

BACKGROUND: Type 2 diabetes mellitus (T2DM) is an independent risk factor for colorectal cancer (CRC), and the patients with CRC and T2DM have worse survival. The human gut microbiota (GM) is linked to the development of CRC and T2DM, respectively. However, the GM characteristics in patients with CRC and T2DM remain unclear. METHODS: We performed fecal metagenomic and targeted metabolomics studies on 36 samples from CRC patients with T2DM (DCRC group, n = 12), CRC patients without diabetes (CRC group, n = 12), and healthy controls (Health group, n = 12). We analyzed the fecal microbiomes, characterized the composition and function based on the metagenomics of DCRC patients, and detected the short-chain fatty acids (SCFAs) and bile acids (BAs) levels in all fecal samples. Finally, we performed a correlation analysis of the differential bacteria and metabolites between different groups. RESULTS: Compared with the CRC group, LefSe analysis showed that there is a specific GM community in DCRC group, including an increased abundance of Eggerthella , Hungatella , Peptostreptococcus , and Parvimonas , and decreased Butyricicoccus , Lactobacillus , and Paraprevotella . The metabolomics analysis results revealed that the butyric acid level was lower but the deoxycholic acid and 12-keto-lithocholic acid levels were higher in the DCRC group than other groups ( P < 0.05). The correlation analysis showed that the dominant bacterial abundance in the DCRC group ( Parvimonas , Desulfurispora , Sebaldella , and Veillonellales , among others) was negatively correlated with butyric acid, hyodeoxycholic acid, ursodeoxycholic acid, glycochenodeoxycholic acid, chenodeoxycholic acid, cholic acid and glycocholate. However, the abundance of mostly inferior bacteria was positively correlated with these metabolic acid levels, including Faecalibacterium , Thermococci , and Cellulophaga . CONCLUSIONS Unique fecal microbiome signatures exist in CRC patients with T2DM compared to those with non-diabetic CRC. Alterations in GM composition and SCFAs and secondary BAs levels may promote CRC development.

Recent studies have found that in the development of epilepsy, cyclic adenosine monophosphate response element binding protein (CREB) may cause recurrent epilepsy by inhibiting the expression of γ-aminobutyric acid, resulting in neuron damage and weakened effect of antiepileptic drug targets. Antiepileptic drugs can not control the extent or frequency of seizures, and then the patients are in a persistent state, hence the development of drug-resistant epilepsy. Therefore, the mechanism of CREB leading to drug-resistant epilepsy was reviewed in this paper, hoping to provide ideas for the treatment of drug-resistant epilepsy patients.

Objective:To explore the application and feasibility of PDCA cycle mode during the initial review of medical ethics committee in the hospital, to further promote the sustainable capacity building of ethics committee.Methods:To improve the quality of initial review management in the hospital ethics committee, PDCA method was used in this study from four aspects that including planning, implementation, inspection and action.Results:Measures adopted including clarifying the scope of ethical review, strengthening the practicability and operability of the review system, standardizing the ethical review procedures, strengthening the substantive review, reinforcing the cooperation among departments, and strengthening the training of medical ethics. Along with the implementation of these measures, ethics committee members were empowered their capacity of conducting initial review, at the same time, investigators also had better understandings and be more serious of the initial review. Furthermore, a PDCA improvement plan was proposed, which including the establishment of independent consultant expert database, the initiative of ethical review data management system, adopting clinical decision analysis methods in ethical review, as well as the improvement of post-approval management and operating procedures.Conclusions:The ethical review management work is continuingly improved under the guidance of PDCA cycle theory. The method of PDCA cycle theory is an ideal model for the long-term development of ethical management.

Objective: In this study, we used HepG2 human hepatocellular carcinoma cells to study the effects of Compound Xishu Granule (CXG) on cell proliferation, apoptosis, and the cell cycle in vitro. We also used a xenograft tumor model to study the anti-tumor effects of CXG and related mechanisms in vivo.Methods: The effect of CXG on cell viability was measured using Cell Counting Kit-8 and a colony for-mation assay. The effect of CXG on apoptosis and the cell cycle was analyzed using flow cytometry. The in vivo anti-tumor effect of CXG was assessed by measuring the volume change in xenograft tumors after drug administration. The CXG anti-tumor mechanism was studied using western blotting assay to detect cell cycle and apoptotic associated proteins. Results: CXG suppressed HepG2 cell proliferation in a time-and dose-dependent manner in vitro. Colony formation experiments showed that CXG administration for 24 h significantly reduced HepG2 cell for-mations (P<.01). Flow cytometric analysis showed that CXG treatment for 48 h promoted apoptosis and blocked HepG2 cells in the G2/M phase. Western blotting results showed that Bax was significantly up-regulated and Bcl-2 was down-regulated in graft tumor tissues and HepG2 cells after CXG administra-tion, which increased the Bax/Bcl-2 ratio. PLK1, CDC25C, CDK1, and Cyclin B1 expression were up-regulated. CXG had a good inhibitory effect on graft tumor growth in vivo. Conclusion: CXG has good anti-tumor effects in vitro and in vivo. In vitro, CXG promoted HepG2 cell apoptosis and induced G2/M phase arrest. In vivo, CXG significantly inhibited graft tumor growth. The CXG mechanism in treating hepatocellular carcinoma may be that CXG can induce abnormal apoptotic and cell cycle associated protein expression, leading to mitotic catastrophe and apoptosis.

Objective: To explore the application value of thyroid alar cartilage(TAC) in the laryngotracheal reconstruction of subglotticstenosis in the paediatric population. Methods: Twelve patients(7 males,5 females; range from 2.3 to 12.0 years) with subglotticstenosis who had undergone laryngotracheal reconstruction procedures at our hospital fromSeptember 2016 to July 2018 were analyzed retrospectively.The degree of stenosis was classified according to Myer-Cotton classification system:grade Ⅱ(n=4),grade Ⅲ(n=6) and grade Ⅳ(n=2). The stenosis planes were subglotticbut did not exceed the 3rd tracheal cartilage ring. Results: Of all 12 patients, 11 were decannulated and 1 failed. All patients with grade Ⅱ and Ⅲ patients were decannulated at one procedure. There were no severe complications such as tube dislogement,asphyxia and unhealed wound. Conclusions The TAC for widening laryngotracheal lumen is relatively simple and reliable for laryngotracheal reconstruction in the pediatric population with subglottic stenosis. This would′t cause any structural damage to the laryngeal cavity.

Objective To investigate the density seasonal fluctuation and insecticide resistance of Anopheles sinensis in the Taibai Lake area and to provide a scientific basis for formulation of Anopheles sinensis control strategy.Methods The surveillance was carried out from June to October in 2013-2016.The adult mosquito density was monitored using human bait trapping method.WHO bioassay method was used to measure the sensibility of mosquitoes to insecticides.Results In 2013-2016,totally 2 318 Anopheles sinensis were captured,the Anopheles sinensis peaked in late July till early August,which were 67-127,317-386,77-89,107-139,respectively.Anopheles sinensis showed high resistance to dichlorodiphenyltrichloroethane,malathion,and initial resistance to propoxur and deltamethrin (mortality ratio:38.10％,41.82％,86.11％,83.02％).Conclusions The Taibai Lake area has a diverse Anopheles sinensis population,its seasonal fluctuations and insecticide resistance monitoring can provide effective guidance for malaria control.In order to prevent the development of resistance to the insecticides,integrated management measures should be adopted in the future.
