		                        			OBJECTIVE To investigate the regulatory effect of autophagy on the resistance of human liver cancer cell Huh7 to lenvatinib. METHODS Using human liver cancer cell Huh7 as subject, the lenvatinib-resist cell model (Huh7-LR) was generated by the low-dose gradient method combined with long-term administration. The sensitivity of parental cell Huh7 and drug-resistant cell Huh7-LR to lenvatinib was detected by using CCK-8 assay and flow cytometry. Western blot assay and GFP-mCherry-LC3 plasmid transfection were performed to detect the expression levels of autophagic protein Beclin-1, autophagic adapter protein sequestosome 1 (p62), microtubule-associated protein 1 light chain 3 (LC3) and autophagic level. Furthermore, an autophagy activation model was constructed by cell starvation, the protein expression of p62 and autophagy level were detected by using Western blot assay and GFP-mCherry-LC3 plasmid transfection, and the effect of autophagy activation on the sensitivity of Huh7-LR cells to lenvatinib was detected by flow cytometry. RESULTS Compared with parental cells, the drug resistance index of Huh7-LR cells was 6.2; protein expression of p62 was increased significantly, while apoptotic rate, protein expression of Beclin-1 and LC3Ⅱ/ LC3Ⅰ ratio were all reduced significantly (P<0.05 or P<0.01); the level of autophagy was decreased to some extent. Autophagy activation could significantly increase the protein expression of p62 in Huh7-LR cells (P<0.05) and autophagy level, and significantly increase its apoptotic rate (P<0.05). CONCLUSIONS Autophagy is involved in lenvatinib resistance, and activating autophagy can reverse the resistance of liver cancer cells to lenvatinib to some extent.

		                        			Background Phenolic compounds, which are widely used as plasticizers, antibacterial agents, and preservatives in industrial production, have endocrine disrupting effects on humans. Previous epidemiological studies on the associations between phenolic compound exposure and blood lipids are mainly based on single measurement of spot urine samples, neglecting potential lag effects of phenolic compounds, and the conclusions are inconsistent. Objective To investigate the effects of short-term exposure to phenolic compounds at different lag days on blood lipid levels in adults. Methods We recruited 143 adults (43 males and 100 females) in Wuhan for three consecutive seasonal rounds of repeated visits: summer and autumn rounds of 2017 and winter of 2018. Morning urine samples were collected for four consecutive days during each round. A set of questionnaires were also distributed on the first day. Physical examinations and fasting venous blood sample collection were conducted on the fourth day.

		                        			We conducted a prospective study to assess the non-inferiority of adjuvant chemotherapy alone versus adjuvant concurrent chemoradiotherapy (CCRT) as an alternative strategy for patients with early-stage (FIGO 2009 stage IB-IIA) cervical cancer having risk factors after surgery. The condition was assessed in terms of prognosis, adverse effects, and quality of life. This randomized trial involved nine centers across China. Eligible patients were randomized to receive adjuvant chemotherapy or CCRT after surgery. The primary end-point was progression-free survival (PFS). From December 2012 to December 2014, 337 patients were subjected to randomization. Final analysis included 329 patients, including 165 in the adjuvant chemotherapy group and 164 in the adjuvant CCRT group. The median follow-up was 72.1 months. The three-year PFS rates were both 91.9%, and the five-year OS was 90.6% versus 90.0% in adjuvant chemotherapy and CCRT groups, respectively. No significant differences were observed in the PFS or OS between groups. The adjusted HR for PFS was 0.854 (95% confidence interval 0.415-1.757; P = 0.667) favoring adjuvant chemotherapy, excluding the predefined non-inferiority boundary of 1.9. The chemotherapy group showed a tendency toward good quality of life. In comparison with post-operative adjuvant CCRT, adjuvant chemotherapy treatment showed non-inferior efficacy in patients with early-stage cervical cancer having pathological risk factors. Adjuvant chemotherapy alone is a favorable alternative post-operative treatment.

		                        			OBJECTIVE To investigate the mechanism of glucose -6-phosphate dehydrogenase (G6PD)-induced sorafenib - resistance in hepatocarcinoma cell based on phoshorylated 3-kinase/protein kinase B (PI3K/Akt)signaling pathway . METHODS Cell lines including hepatocarcinoma cell Huh 7,sorafenib-resistant cell Huh 7-SR,G6PD overexpressed cell Huh 7-G6PD and its control cell Huh 7-CT,and compounds including G 6PD inhibitor (6-Aminonicotinamide,6AN)and sorafenib were used as objects or intervention drugs in these research . CCK8 assay was applied to evaluate cell viability . The protein levels of G 6PD and the phosphorylation levels of PI 3K/Akt signaling pathway were detected by Western blot . Flow cytometry was utilized to investigate cell apoptosis. RESULTS Compared with Huh 7 cells,the protein level of G 6PD was significantly increased in Huh 7-SR cells (P< 0.05). The combination of 6AN and sorafenib reduced cell viability of Huh 7-SR cells (P<0.01). However,compared with Huh 7- CT,increased cell viability and decreased cell apoptosis rate were observed in Huh 7-G6PD cells while cells were treated with sorafenib(P<0.01). Mechanistically,the phosphorylation levels of PI 3K and Akt were significantly decreased in Huh 7-SR cells that were treated with 6AN(P<0.05). Moreover,under the condition of no drug intervention ,the phosphorylation levels of PI 3K and Akt were significantly elevated in Huh 7-G6PD cells when compared with Huh 7-CT(P<0.01). CONCLUSION G6PD could induce sorafenib -resistance in hepatocarcinoma cell by activating PI 3K/Akt signaling pathway .

		                        			Objective:To explore the changes of intracranial pressure in intensive care unit (ICU) patients during the occurrence and evolution of delirium by using bedside ultrasound to measure the optic nerve sheath diameter (ONSD) to evaluate intracranial pressure.Methods:A retrospective observational study was conducted. Adult patients who developed delirium during hospitalization in the general ICU of Beihai People's Hospital from October 2020 to November 2021 were enrolled, and patients who did not have ultrasonographic ONSD records within 24 hours after the diagnosis of delirium were excluded. The ONSD measured before delirium was recorded as ONSD 0, the ONSD measured within 24 hours of the onset of delirium recorded as ONSD 1, and the ONSD reexamined after ONSD 1 recorded as ONSD 2. Patients were divided into intracranial hypertension group (ONSD 1 > 5 mm) and normal intracranial pressure group (ONSD 1 ≤ 5 mm) according to the size of ONSD 1. According to the outcome of delirium, the patients were divided into cured, improved, and non-improved groups. The reduction ratio of ONSD 2 to ONSD 1 in the three groups were calculated and compared. Pearson correlation test was used to analyze the correlation between fluid balance and ONSD changes after delirium. Results:There were 43 patients, including 40 cases in the intracranial hypertension group (the incidence rate was 93.0%), 3 cases in the normal intracranial pressure group, 23 cases were cured, 13 cases were improved, and 7 cases were not improved. In the intracranial hypertension group, 11 cases had ONSD 0 and ONSD 1 records, and ONSD 1 was significantly higher than ONSD 0 [mm: 5.88±0.61 vs. 5.34±0.57, 95% confidence interval (95% CI) -0.85 to -0.23, P = 0.003]. The reduction ratio of ONSD 2 to ONSD 1 in the cured group was significantly higher than that in the improved group and the non-improved group [(12.04±6.20)% vs. (5.68±4.10)%, (0.17±3.96)%; 95% CI were 2.37 to 10.33, 6.41 to 17.31, P values were 0.003 and 0.000, respectively]. The correlation analysis showed that the reduction ratio of ONSD 2 to ONSD 1 was negatively correlated with fluid balance ( r = -0.42, 95% CI was -0.66 to -0.10, P = 0.012). Conclusions:The incidence of intracranial hypertension in ICU delirium patients is high. A more pronounced decrease in intracranial pressure predicts a better delirium outcome. Dynamic ONSD measurement can provide valuable information for the prevention and treatment of delirium.

		                        			OBJECTIVE:To i nvestigate the spectrum-effect relationship of analgesic and anti-inflammatory effects of ethyl acetate extract from Zhuang medicine Stahlianthus involucratus from different habitats. METHODS :Ten batches of S. involucratus from different habitats were used as samples to investigate the anti-inflammatory and analgesic activities of ethyl acetate extracts by xylene induced ear swelling test and acetic acid induced writhing test in mice. HPLC fingerprints of 10 batches of ethyl acetate extract from S. involucratus were established and their similarity was evaluated by using Similarity Evaluation System of TCM Chromatogram Fingerprint (2012 edition),and the common peaks were identified by comparison with the control. The spectrum-effect relationship of anti-inflammatory and analgesic effects of ethyl acetate extract from S. involucratus were analyzed on the basis of Pearson correlation coefficient (auricle swelling degree and writhing times in 15 min as pharmacodynamic indexes )and Grey relational analysis (inhibition rate of ear swelling and  analgesic rate as pharmacodynamic indexes ). RESULTS : batches of ethyl acetate extract from S. involucratus had  obvious anti-inflammatory and analgesic effects ; inhibition rates of ear swelling in mice were 46.43%-55.16%,and the  analgesic rates of mice were 45.56%-52.72%. A total of 18  common peaks were identified in 10 batches of samples ,andthe similarity between them and the control fingerprint was  0.994-0.997. Compared with substance control ,the pea ks 1,2 and 4 were identified as protocatechuic acid , p-hydroxy- 0771-4953513。E-mail:liangjie1101@126.com benzoic acid and p-hydroxybenzaldehyde,respectively. Results  of Pearson correlation analysis showed that peak 10 and peak 18 were significantly negative correlated with auricle swelling degree and writhing times in 15 min(r were values -0.853,-0.738,P values were 0.002,0.015,respectively). Results of Gray correlation degree analysis showed that the correlation degree of 18 common peaks with inhibition rate of ear swelling and analgesic rate were all greater than 0.65;among them ,peaks 14,1(protocatechuic acid ),17,9,4(p-hydroxybenzaldehyde),2(p-hydroxybenzoic acid ), 16,7 and 6 showed the relatively high correlation degree (correlation degree >0.7);peak 1(protocatechuic acid ),17,14,9,16,2 (p-hydroxybenzoic acid )and 4(p-hydroxybenzaldehyde)showed the relatively high correlation degree (correlation degree >0.7). CONCLUSIONS:The ethyl acetate extract of S. involucratus show good anti-inflammatory and analgesic effects. Peak 1 (protocatechuic acid ),2(p-hydroxybenzoic acid ),10,14,17,18 may be its main active ingredients.

		                        			Objective:To investigate the improvement and clinical effect of lip depilation with 810 nm semiconductor laser.Methods:Retrospective analysis was performed on female labial hair removal patients admitted to Bethune Hospital in Shanxi from January 2017 to October 2018. The patients who visited the clinic from January 2018 to October 2018 were taken as the experimental group, and those who visited the clinic from January 2017 to December 2017 were taken as the control group. A combination model of super hair removal(SHR) + hair removal(HR) was adopted to perform the treatment with 810 nm YfTON semiconductor freezing point laser hair removal. The experimental group was treated with surface anesthetic and SHR mode dumbbell sliding mode 8 J/cm 2+ HR mode with high energy (starting from the upper limit of reference energy value), and the patients were treated with local drum and chin coordination. In the control group, no surface anesthetic was applied, and SHR mode was used for linear round-trip sliding + HR mode for reference energy treatment. After the third and fifth treatment, the patients in the two groups were treated with a hair size of 1 cm×1 cm on one side of the mouth corner with heavy hair. A hair analyzer was used to count the number of similar hairs visible to the naked eye at a social distance of about 1 meter. The final hair removal rate was calculated as excellent (70%-90%, including 70%), as improvement (40%-70%, including 40%), as invalid (<40%). The depilation rate after 3 and 5 treatments was compared between the 2 groups, the number of treatments was analyzed, and the recurrence rate and comfort level of the patients were followed up 6 months after treatment. Wilcoxon rank sum test was used to compare the measurement data. Comparison of counting data was tested, and P<0.05 was considered statistically significant. Results:A total of 200 patients were included in this study, including 100 in the experimental group, with an age of (28.58±6.01) years. The control group included 100 patients (28.57±6.07) years old. The skin type of patients was performed according to Fitzpatrick and Chinese characteristics Ⅱ-Ⅳ. After statistical test, there were no statistically significant differences in age and skin type between the two groups. After half a year of follow-up, the average number of treatment times in the experimental group was 5(5, 6) times, lower than that in the control group 7(6, 8) times( T=-9.279, P<0.001). The three and five depilation rates of the experimental group were[70.0%(68.0%, 74.8%), 86.0%(83.0%, 88.0%)], and the final depilation rates of the experimental group were 89.0%(86.7%, 90.0%), all higher than those in the control group[40.0%(37.0%, 42.0%), 72.0%(70.0%, 74.0%), 86.5%(85.0%, 88.0%)]. The differences between the two groups were statistically significant ( T3=43.986, T5=25.151, Tfinal=5.547, all P< 0.001). The intermittent times of single sliding treatment in the experimental group ≤2 times, compared with the control group > 2 times, the comfort level was improved. No blisters or coloration occurred in any of the patients. Patients in the 2 groups were followed up for half a year after the last hair removal. In the 2 groups, there were sparse new fine hairs and soft hair growth that were not included in the hair count, and the included hairs were thinner than those before the treatment. Conclusions:Compared with the control group, the treatment cycle is shorter, the efficiency is higher and the comfort level of the patients is higher in the experimental group.
