BackgroundSuicidal ideation serves as a sensitive predictive indicator for non-suicidal self-injury （NSSI） behavior， and NSSI behavior brings profound effects to both mental and physical health of senior high school students. Existing studies have made exploration on the relationship among insomnia， anxiety and NSSI behavior in the general population， but the internal mechanism of NSSI behavior in senior high school students with suicidal ideation requires further study. ObjectiveTo explore the pathway of anxiety between insomnia and NSSI behavior in senior high school students， so as to provide references for the intervention on NSSI behavior in such demographic. MethodsFrom December 10 to 15， 2021， cluster sampling was adopted to select 2 572 senior high school students across three senior high schools in Hubei Province as the research objects. Assessment was conducted by using Insomnia Severity Index （ISI）， Generalized Anxiety Disorder Scale-7 item （GAD-7） and Adolescents Self-Harm Scale. Spearman correlation analysis was conducted to examine the correlation among scores of scales finished by senior high school students with suicidal ideation. Model 4 from the SPSS 20.0 Process 4.2 was employed to test the mediating path of anxiety between insomnia and NSSI behavior. ResultsA total of 2 421 valid questionnaires （94.13%） were recovered， which revealed 554 cases （22.88%） with suicidal ideation and 408 cases （16.85%） with NSSI behavior. The scores of ISI， GAD-7 and Adolescents Self-Harm Scale of senior high school students with suicidal ideation were higher than those of students without suicidal ideation （Z=17.124， 20.611， 21.314， P<0.01）. As correlation analysis showed， the ISI score of senior high school students with suicidal ideation was positively correlated with scores of GAD-7 and Adolescents Self-Harm Scale （r=0.646， 0.354， P<0.01）， and GAD-7 score was positively correlated with the score of Adolescents Self-Harm Scale （r=0.375， P<0.01）. Among senior high school students with suicide ideation， anxiety acted in a mediating role between insomnia and NSSI behavior， with effect value of 0.111 （95% CI： 0.053~0.185）， accounting for 53.88% of the total effect. ConclusionInsomnia of senior high school students with suicidal ideation can not only directly affect NSSI behavior， but also indirectly affect NSSI behavior through anxiety. ［Funded by Research Project of Jingzhou Science and Technology Innovation Think Tank in 2022 （number， JZCXZK202209）］

Objective: To study the involvement of MAPK MEK/ERK signaling transduction pathway in the apoptosis process of SW620 tumor cell line and the inhibition effect of resveratrol. Methods: SW620 cell lines were divided into 5 groups, namely, control group, PD98059 group, low-dose resveratrol group, mid-dose resveratrol group and high-dose resveratrol group. The inhibition rate of cell proliferation was detected by MTT method. The expression of apoptotic molecules and MEK/ERK signaling pathway related proteins were assayed by real-time PCR and Western blotting. Results: Compared with control group, the proliferation of cells treated with resveratrol was significantly inhibited. In the case of apoptotic molecules, the expression of Bax, Caspase 3 and Caspase 9 was increased significantly while the expression of anti-apoptotic molecule Bcl2 was decreased significantly in resveratrol groups with a dose-dependent manner. In the case of molecules in MEK/ERK signaling pathway, the expression of Ras, Raf, MEK and ERK1/2 was decreased significantly in resveratrol groups with a dose-dependent manner. Conclusions: PD98059 and resveratrol can effectively inhibit the proliferation of SW620 through inhibiting the MEK/ERK signaling pathway.

Parathyroid adenoma is a major cause of primary hyperparathyroidism. Treatment usually involves the surgical removal of one or more parathyroid glands. However, specific localising techniques have boosted the development of nonsurgical, minimally invasive procedures, such as percutaneous radiofrequency ablation (RFA) under ultrasonographic guidance, which are gaining popularity as a method of treatment. This paper reports two male patients who presented with hypercalcaemia (highest serum calcium level 4.56 mmol/L and 4.57 mmol/L, respectively) and hyperparathyroidism (highest serum parathyroid hormone [PTH] level 772 ng/L and > 1,900 ng/L, respectively) due to solitary parathyroid adenoma. Four days after percutaneous RFA, the serum calcium levels in both patients decreased and PTH levels showed a significant decreasing trend. Both patients recovered well with normal levels of calcium and improvement of symptoms. Thus, we conclude that RFA may be a safe and effective therapeutic option in the treatment of parathyroid adenoma.

ObjectiveTo retrospectively analyze the clinical data of 52 patients with coronavirus disease-2019 （COVID-19） and explore the clinical efficacy of modified Sanxiaoyin on mild/moderate COVID-19 patients. MethodThe propensity score matching method was used to collect the clinical data of mild or moderate COVID-19 patients enrolled in the designated hospital of the Second Hospital of Jingzhou from December 2019 to May 2020. A total of 26 eligible patients who were treated with modified Sanxiaoyin were included in the observation group， and the 26 patients treated with conventional method were the regarded as the control. The disappearance of clinical symptoms， disappearance time of main symptoms， efficacy on traditional Chinese medicine （TCM） symptoms， hospitalization duration， laboratory test indicators， and CT imaging changes in the two groups were compared. ResultThe general data in the two groups were insignificantly different and thus they were comparable. After 7 days of treatment， the disappearance rate of fever， cough， fatigue， dry throat， anorexia， poor mental state， and poor sleep quality in the observation group was higher than that in the control group （P<0.05）， and the difference in the disappearance rate of expectoration and chest distress was insignificant. For the cases with the disappearance of symptoms， the main symptoms （fever， cough， fatigue， dry throat， anorexia， chest distress） disappeared earlier in the observation group than in the control group （P<0.01）. After 7 days of treatment， the scores of the TCM symptom scale of both groups decreased （P<0.01）， and the decrease of the observation group was larger that of the control group （P<0.01）. All patients in the two groups were cured and discharged. The average hospitalization duration in the observation group ［（12.79±2.68） d］ was shorter than that in the control group ［（15.27±3.11） d］ （P<0.01）. The effective rate in the observation group （92.31%， 24/26） was higher than that in the control group （76.92%， 20/26） . After 7 days of treatment， the lymphocyte （LYM） count increased （P<0.05）， and white blood cell （WBC） count and neutrophil （NEUT） count decreased insignificantly in the two groups. Moreover， levels of C-reactive protein （CRP）， erythrocyte sedimentation rate （ESR）， and procalcitonin （PCT） reduced in the two groups after treatment （P<0.01） and the reduction in the observation group was larger than that in the control group （P<0.01）. Through 7 days of treatment， the total effective rate on pulmonary shadow in the observation group （90.00%， 18/20） was higher than that in the control group （77.27%， 17/22） （P>0.05） and the improvement of lung shadow in the observation group was better than that in the control group （P<0.01）. ConclusionModified Sanxiaoyin can significantly alleviate fever， cough， fatigue， anorexia， chest distress， poor sleep quality， and other symptoms of patients with mild or moderate COVID-19， improve biochemical indicators， and promote the recovery of lung function. This paper provides clinical evidence for the application of modified Sanxiaoyin in the treatment of mild or moderate COVID-19.

OBJECTIVE: To observe the effect of thumb-tack needles based on "Biaoben acupoint compatibility" on sequela symptoms, mental state and pulmonary ventilation function in patients with coronavirus disease 2019 (COVID-19) during recovery period. METHODS: Fifty cases of COVID-19 during recovery period were randomly divided into an observation group and a control group, 25 cases in each group. The patients in the observation group were treated with thumb-tack needles at Guanyuan (CV 4), Zusanli (ST 36) and Taiyuan (LU 9). The patients in the control group were treated with sham thumb-tack needles at identical acupoints as the observation group. The treatment in the two groups was given once a day, 7-day treatment was taken as a course of treatment, and totally two courses of treatment were given. The TCM symptom score, Hamilton anxiety scale (HAMA) score, Hamilton depression scale (HAMD) score, pulmonary function (forced vital capacity [FVC], forced expiratory volume in the first second [FEV1], peak expiratory flow [PEF]), the severity of pulmonary ventilation dysfunction and pulmonary imaging changes in the two groups were compared before and after treatment. RESULTS: Compared before treatment, the total scores and each item scores of TCM symptom scale, HAMA scores and HAMD scores in the two groups were reduced after treatment (P<0.05). Except for the symptom scores of dry throat and dry stool, the total score and each item score of TCM symptom scale, HAMA score and HAMD score in the observation group were lower than those in the control group (P<0.05). Compared before treatment, FVC, FEV1 and PEF in the two groups were increased after treatment (P<0.05), and those in the observation group were higher than the control group (P<0.05). The severity of pulmonary ventilation dysfunction in the two groups was reduced after treatment (P<0.05), and the severity in the observation group was better than that in the control group (P<0.05). After treatment, the lung shadow area in the two groups was decreased (P<0.05), and that in the observation group was smaller than the control group (P<0.05). The improvement of imaging change in the observation group was better than that in the control group (P<0.05). CONCLUSION The thumb-tack needles based on "Biaoben acupoint compatibility" could significantly reduce the sequela symptoms, anxiety and depression in patients with COVID-19 during recovery stage, and improve the pulmonary ventilation function.

Conclusion:Undergraduates may be more susceptible to academic environment than graduates and doctoral students, showing that the learning stability of undergraduates is the relatively the worst. Undergraduates most recognize online courses, and different educational levels have different demands for online courses.

BACKGROUNDGreen tea has been shown to improve cholesterol metabolism in animal studies, but the molecular mechanisms underlying this function have not been fully understood. Long non-coding RNAs (lncRNAs) have recently emerged as a major class of regulatory molecules involved in a broad range of biological processes and complex diseases. Our aim was to identify important lncRNAs that might play an important role in contributing to the benefits of epigallocatechin-3-gallate (EGCG) on cholesterol metabolism.

METHODSMicroarrays was used to reveal the lncRNA and mRNA profiles in green tea polyphenol(-)-epigallocatechin gallate in cultured human liver (HepG2) hepatocytes treated with EGCG and bioinformatic analyses of the predicted target genes were performed to identify lncRNA-mRNA targeting relationships. RNA interference was used to investigate the role of lncRNAs in cholesterol metabolism.

RESULTSThe expression levels of 15 genes related to cholesterol metabolism and 285 lncRNAs were changed by EGCG treatment. Bioinformatic analysis found five matched lncRNA-mRNA pairs for five differentially expressed lncRNAs and four differentially expressed mRNA. In particular, the lncRNA AT102202 and its potential targets mRNA-3-hydroxy-3-methylglutaryl coenzyme A reductase (HMGCR) were identified. Using a real-time polymerase chain reaction technique, we confirmed that EGCG down-regulated mRNA expression level of the HMGCR and up-regulated expression of AT102202. After AT102202 knockdown in HepG2, we observed that the level of HMGCR expression was significantly increased relative to the scrambled small interfering RNA control (P < 0.05).

CONCLUSIONSOur results indicated that EGCG improved cholesterol metabolism and meanwhile changed the lncRNAs expression profile in HepG2 cells. LncRNAs may play an important role in the cholesterol metabolism.

OBJECTIVETo investigate the effect of Earthworm decoction on the airway inflammation of experimental bronchial asthma in guinea pigs and inquire into the mechanism in the decoction.

METHODForty-eight guinea pigs were randomly divided into six groups: the control group, the model group, the dexamethasone group, the Xiaoqinglong decoction group, the earthworm decoction large dosage group and the Earthworm decoction low dosage group, 8 guinea pigs in each group. Except the control group, the other groups were sensitized with ovalbumin (OVA) by a combination of intraperitional injection and repeated intranasal challenges to establish the guinea pigs asthma model. However, in the control group, normal saline was used. The morphological changes of bronchial tube, the lung tectology and the inflammation germ cell quantity of eosinophils (Eos), lymphocytes (Ly), neutrophils (Neu) and total blood cells in the blood and bronchoalveolar lavaga fluid (BALF) were examinated in each group respectively.

RESULTThe levels of Eos, Ly, Neu and total cell quantity in the blood and BALF after the earthworm decoction treatment in the large dosage group were significantly lower than those in the model group (P <0.01), and in the low dosage group were lower too (P <0.05). The Earthworm decoction large dosage could obviously improve the bronchial tube epidermis damage, the mucous membrane gland proliferation and hydrops, asthma pathology change and basilar membrane accumulation. Eos apoptosis was obsered in the bronchoalveolar, blood and BALF. The Earthworm decoction small dosage had a similar effect but slightly to the large dosage.

CONCLUSIONThe Earthworm decoction can lighten the airway inflammation in asthmatic guinea pigs, its mechanism is related with the inhibition of Eos infiltration, acceleration of Eos apoptosis and improvement of the bronchial tube and the lung tectology changes. The effect of the decoction is dose-dependent.
