0.05). Conclusion: Bibliotherapy is helpful for mental health in the college students.

Objective To study the clinical characteristics of tuberculosis in oral and maxillofacial region,and to provide reference in early diagnosis and early treatment. Methods The clinical data of 132 patients were analyzed retrospectively. ResultsIn all cases, male to female ratio of 1∶1.69, the average age of 38.7 years, the group of 15 ～40year-old had higher incidence. Al1 parts of oral and maxillofacial region could be involved. In all 132 cases,107 cases were treated by surgery and drugs,25 cases by drugs only. Conclusion The local sign of tuberculosis in oral and maxillofacial region was atypical ,so it was likely to misdiagnosis. Definitive diagnosis relied on pathological examination. Operations played an important role in the cases of unifocal lymph nodes tuberculosis,oral mucosal tuberculosis, multifocal concentrated lymph nodes tuberculosis and salivary tuberculosis, while the therapy of multifocal sporadic lymph nodes tuberculosis and osseous tuberculosis should be relied on the medicine.

Objective:To evaluate the effect of antiviral therapy on HBV reactivation and liver function after liver resection in patients with hepatocellular carcinoma (HCC). Methods:A total of 174 HBV-DNA(?) HCC patients were recruited into two groups:antiviral ther-apy group (66 cases) and control group (108 cases). In the antiviral group, patients were given entecavir dispersible tablet, whereas no antiviral therapies were given in the control group. The HBV reactivation and liver function index rates were statistically analyzed. Re-sults:Rates of HBV reactivation after hepatectomy were 3.0%and 27.8%in the antiviral therapy group and control group, respectively. Multivariate analysis revealed that minor hepatectomy (HR, 4.695;95%CI, 1.257-17.537, P=0.021) and no antiviral therapy (HR, 8.164;95%CI, 1.831-36.397, P=0.006) were independent risk factors for HBV reactivation. The levels of ALT, TBil, ALB, and PT within 7 days af-ter liver resection were similar between the antiviral therapy group and the control group and between the reactivation group and no-reactivation group. However, the ALT and ALB levels were significantly better in the antiviral group compared with that in the control group after 30 days. Conclusion:HBV reactivation can occur after liver resection for HBV-DNA(?) HCC patients. Preoperative antiviral therapy can reduce the risk of HBV reactivation, thus protecting liver function in patients undergoing liver resection.

Objective To investigate the role and mechanism of inflammatory response of Kupffer cells induced by Chemerin in the progression of non-alcoholic fatty liver disease (NAFLD) in mice.Methods Wortmannin was used to treated on KCs which pre-treated with Chemerin in vitro for two hours,and treated on C57BL/6J mice which was fed with a high-fat die.Levels of cytokines in supernatant/serum were tested by enzyme-linked immunosorbent assays(ELISA);mRNA and protein levels of KCs' Chemokine-like receptor 1 (CMKLR) and nucleotide oligomerization domain (NOD)-like receptor family pyrin domain containing 3 (NLRP3) in vivo and vitrowere detected by real time polymerase chain reaction(real time-PCR) and Western blot;changes of mouse weight were recorded;insulin resistance and glucose tolerance were detected;the severity of liver steatosis was evaluated by HE staining combined with NAS score.Results The levels of interleukin 1β (IL-1β) and IL-18 in the KCs and mice treated with wortmannin were significantly lower than the KCs treated with Chemerin only and mice fed with high fat diet only.The mRNA and protein levels of CMKLR1 and inflammasome 3 (NLRP3) were significantly lower in the KCs and mice treated with Wortmannin than the KCs treated with Chemerin only and mice fed with high fat diet only.In addition,changes in mouse weight,hepatic steatosis,liver function,insulin resistance and glucose tolerance were much milder in mice treated with Wortmannin than those mice fed with high fat diet.Conclusion Wortmannin alleviates liver steatosis and inflammation mediated by KCs via down-regulating the expression of CMKLR1 and NLRP3 in high fat diet fed mice.

Objective:To investigate the clinical impact factors of liver regeneration after hemihepatectomy in patients with hepatocellular carcinoma (HCC).Methods:Patients who underwent hemihepatectomy due to HCC from Sep 2013 to Sep 2018 were included in the study. Liver volumes were calculated by perioperative simulations to analyze the influencing factors of postoperative liver regeneration, and to compare the albumin bilirubin (ABLI) score and the end-stage liver disease (MELD) score at weeks 1, 5, 9, and 13 after operation.Results:A total of 163 patients were included, of which 13 developed postoperative liver failure. The median liver regeneration rates at 1, 5, 9 and 13 weeks after operation were 22.0%, 32.2%, 33.7% and 35.4%, respectively. Multivariate analysis showed that remnant liver volume (RLV) <611.1 cm 3, %RLV and liver cirrhosis were the influencing factors of liver regeneration. ALBI score and MELD score were lower in the low regeneration group compared to the high regeneration group in the first 5 weeks after operation. Conclusion:RLV and cirrhosis are influential factors in postoperative liver regeneration. Liver regeneration proceeded rapidly within 1 week and slowed down until week 5.

Objective To observe the effects of amarogentinon liver cancer stem cells (LCSCs) after insufficient thermal ablation and its mechanism. Methods A insufficient thermal ablation model of HepG2 cells was established by water bath method.The percentage of CD133-positive LCSCs and the mRNA and protein levels of CD133 were detected by flow cytometry, qRT-PCR and Western blot.The insufficient thermal ablation model of HepG2 cells was treated with variable doses of amarogentin for 24 h; the percentage of CD133-positive LCSCs, the proliferation and apoptosis of liver cancer cells, and the mRNA and protein levels of CD133, TBC1D15, and p53were detected by flow cytometry, qRT-PCR and Western blot. Results The percentage of CD133-positive HepG2 cells and the mRNA and protein levels of CD133 and TBC1D15in the insufficient thermal ablation model were significantly higher than those in the normal HepG2 cells.Amarogentin then markedly decreased the percentage of CD133-positive LCSCs, the proliferation rate of HepG2 cells, and the mRNA and protein levels of CD133 and TBC1D15 in the insufficient thermal ablationresidual model (all P < 0.05);inversely, the apoptosis rate of HepG2 cells and the phosphorylated levels of p53 in the insufficient thermal ablation model were significantly increased (all P < 0.05). Conclusion Amarogentin could reduce the proportion of LCSCs after insufficient thermal ablation, inhibit the proliferation, and promote the apoptosis of LCSCs, which maybe associated with increasing the phosphorylation of p53 and inhibiting the expression of TBC1D15.

Objective: To explore the correlation between standard remnant liver volume(SRLV) and post-hepatectomy liver failure (PHLF)in patients with hepatocellular carcinoma(HCC)and cirrhotic livers.Methods:In total,181 patients who underwent hemihepa-tectomy in Affiliated Tumor Hospital of Guangxi Medical University from September 2013 to August 2016 were enrolled in the study. Total liver,tumor,remnant liver,and resected liver volumes were measured using the Myrian liver surgical planning system before sur-gery. Intraoperative resected liver volume (including resected normal liver and tumor volumes) were collected using the drainage method.The patients were divided into the PHLF(22 cases)and non-PHLF groups(159 cases)according to whether PHLF occurred based on the"50/50"criteria.The risk factors of PHLF were then explored.The cut-off of SRLV and efficiency of predicting PHLF were analyzed in the subgroup of patients with cirrhotic livers.The grade of liver cirrhosis was retrospectively analyzed using helical comput-ed tomography(CT).Results:Twenty-two of the 181 patients developed PHLF and one died of it.Preoperative total bilirubin levels and SRLV were identified as independent factors for predicting PHLF using a Logistic regression model.In total,102 patients with cirrhotic livers were selected in subgroup analysis based on postoperative cirrhotic pathology.Eighteen patients developed PHLF and one died of PHLF in the subgroup.Using receiver-operating characteristic(ROC)curve analysis,340 mL/m2was the cut-off of SRLV for patients with HCC and cirrhotic livers(area under the curve:0.861,P<0.01;sensitivity and specialty rates were 94.4% and 74.7%,respectively). Eighty-four cases were of grade Ⅰ or Ⅱ cirrhosis,18 cases were of grade Ⅲ cirrhosis,and there were no cases of grade Ⅳ cirrhosis based on retrospective analysis using helical CT.Conclusions:Patients with cirrhotic livers with an anticipated SRLV of≤340 Ml/m2after he-patic resection are at increased risk for PHLF after emihepatectomy.

This article aimed to summarise the clinical experience of Professor XIONG Jibai in treating henoch-schonlein purpura （HSP） from the perspective of "simultaneous treatment of wind and blood". HSP was devided into acute phase and transitional phase in clinic. It was considered that the wind pathogen exists throughout the disease course， and the treatment is guided by the "four methods of treating blood" in TANG Rongchuan's Treatise on Blood Syndromes - Blood Vomiting （《血证论·吐血》）， which are stanching bleeding， expelling stasis， tranquilising blood， and tonifying blood. In the acute phase， wind-heat damaging collateral symdrome and blood-heat frenetic flow syndrome are common， which could be treated by the method of cooling blood to dispel wind， and eliminating stasis to stop bleeding， with self-prescribed modified Ziping Xiaofeng Powder （紫萍消风散）； in the transitional phase， syndrome of effulgent fire due to yin deficiency and syndrome of qi deficiency failing to control are common， which could be treated by the method of tranquilising blood and tonifying deficiency， with modified Zhibai Dihuang Decoction （知柏地黄汤） and Guipi Decoction （归脾汤）. At the same time， it is believed that wind-related medicinal has the function of eliminating stasis， stanching bleeding， and cooling blood， and the wind-related medicinal should be used throughout the treatment.

OBJECTIVE To analyze the traditional Chinese medicine （TCM） emergency management policy texts in China， reveal the characteristics， problems and improvement directions of Chinese medicine emergency management policies in China， and provide references and lessons for improving the level of Chinese medicine emergency management. METHODS Twenty-four TCM emergency management policy texts issued at the central level from 2016 to 2023 were coded and analyzed using Nvivo11 software to construct a three-dimensional analysis framework based on policy tools， stakeholders and policy strength. RESULTS In the policy tools dimension， the environmental type was the most （46.74%）， the supply type was the second （31.80%）， and the demand type was the least （21.46%）； in the stakeholder dimension， there were more healthcare institutions （40.63%） and government departments （31.25%）， and fewer healthcare workers （14.84%） and residents （13.28%）； in the policy strength dimension， the overall policy strength was poor， and the differences in effectiveness across policy instruments and stakeholders were more significant. The cross-cutting results showed that there was a certain degree of mismatch in policy instruments， stakeholders and policy strength. CONCLUSIONS The use of supply-oriented policy tools is slightly lacking， and the use of policy tools should be optimized in a coordinated manner； the distribution of stakeholders is relatively unbalanced， and synergies among stakeholders should be enhanced； the overall strength of policies is poor， and the top-level design of relevant policies should be improved.

OX40 is a costimulatory receptor that is expressed primarily on activated CD4⁺, CD8⁺, and regulatory T cells. The ligation of OX40 to its sole ligand OX40L potentiates T cell expansion, differentiation, and activation and also promotes dendritic cells to mature to enhance their cytokine production. Therefore, the use of agonistic anti-OX40 antibodies for cancer immunotherapy has gained great interest. However, most of the agonistic anti-OX40 antibodies in the clinic are OX40L-competitive and show limited efficacy. Here, we discovered that BGB-A445, a non-ligand-competitive agonistic anti-OX40 antibody currently under clinical investigation, induced optimal T cell activation without impairing dendritic cell function. In addition, BGB-A445 dose-dependently and significantly depleted regulatory T cells in vitro and in vivo via antibody-dependent cellular cytotoxicity. In the MC38 syngeneic model established in humanized OX40 knock-in mice, BGB-A445 demonstrated robust and dose-dependent antitumor efficacy, whereas the ligand-competitive anti-OX40 antibody showed antitumor efficacy characterized by a hook effect. Furthermore, BGB-A445 demonstrated a strong combination antitumor effect with an anti-PD-1 antibody. Taken together, our findings show that BGB-A445, which does not block OX40-OX40L interaction in contrast to clinical-stage anti-OX40 antibodies, shows superior immune-stimulating effects and antitumor efficacy and thus warrants further clinical investigation.
