Methamphetamine abuse and HIV infection are extremely serious public health and social problems facing the world today. Methamphetamine and HIV-1 Tat protein can induce neurotoxicity in an individual and synergistic way, and neuroinflammation is one of the most important mechanisms for ca-using neurotoxicity. Neuroinflammation can be mediated by glial cells, cytokines, NLRP3 inflammasomes, etc. This paper reviews the research progress of neuroinflammation induced by methamphetamine and HIV-1 Tat protein in recent years, with the aim of providing reference and basis for further exploration of the mechanisms of neuroinflammation caused by them and effective drug intervention targets in the future.

Metabolic associated fatty liver disease (MAFLD) has become a prevalent chronic liver disease worldwide because of lifestyle and dietary changes. Gut microbiota and its metabolites have been shown to play a critical role in the pathogenesis of MAFLD. Understanding of the function of gut microbiota and its metabolites in MAFLD may help to elucidate pathological mechanisms, identify diagnostic markers, and develop drugs or probiotics for the treatment of MAFLD. Here we review the pathogenesis of MAFLD by gut microbiota and its metabolites and discuss the feasibility of treating MAFLD from the perspective of gut microbes.

Objective:To investigate the effect of early postoperative enteral nutrition(EN)on postoperative rehabilitation and inflammation after laparoscopic radical gastrectomy for gastric cancer,in order to provide reference for postoperative rehabilitation of such patients.Methods:Patients who received laparoscopic assisted radical gastrectomy in Department of Gastrointestinal Surgery of The First Affiliated Hospital of Bengbu Medical College from January 2020 to December 2022 were included in the analysis.According to the different ways of postoperative nutritional treatment,patients were divided into the observation group(early postoperative EN group)and the control group(parenteral nutrition group),and indexes such as postoperative rehabilitation,abdominal drainage flow and the level of inflammatory mediators in drainage fluid were compared between the two groups.Results:A total of 81 patients were included,including 41 in the observation group and 40 in the control group.Interval of the first postoperative exhaust(t=3.806;P＜0.001)and resuming diet day(t=5.510;P＜0.001),and length of postoperative hospital stay(t=2.401;P=0.019)in the observation group were shorter than those in the control group.Levels of peripheral blood albumin(t=14.040;P＜0.001)and prealbumin(t=9.832;P＜0.001)of the observation group at postoperative day(POD)5 were significantly higher than those of the control group,but there was no significant difference in hemoglobin level(t=1.477;P=0.144).The level of CRP in peripheral blood of the observation group at POD 5(t=7.758;P＜0.001)and the incidence of postoperative SIRS[(12.2％,5/41)vs(32.5％,13/40),x2=4.830;P=0.028)]were significantly lower than those in the control group.The average drainage volume(t=6.858;P＜0.001),drainage removal time(t=5.016;P＜0.001),and TNF-α level(t=4.993;P＜0.001)and IL-6 level(t=20.640;P＜0.001)in postoperative drainage at POD 5 were significantly lower in the observation group than those in the control group.Conclusion:Early postoperative EN could accelerate the rehabilitation process after laparoscopic radical gastrectomy,improve postoperative nutritional status,and reduce abdominal inflammation.

Objective: To explore the efficacy of adjuvant programmed cell death 1 (PD-1) monoclonal antibody immunotherapy in Chinese patients with resected stage Ⅱ-Ⅲ melanoma. Methods: A total of 296 patients who underwent radical surgery for stage Ⅱ-Ⅲ cutaneous orlimb melanoma at Fudan University Shanghai Cancer Center and Shanghai Electric Power Hospital between 2017 and 2021 and received adjuvant PD-1 monoclonal antibody immunotherapy, low-dose interferon (IFN), or observational follow-up were enrolled in this study. Patients were divided into the PD-1 monoclonal antibody group (164 cases) and the IFN or observation group (IFN/OBS group, 132 cases) based on postoperative adjuvant treatment methods. Patients' disease recurrence and survival were observed. Results: Among the 296 patients, 77 had cutaneous melanoma and 219 had limb melanoma; 110 were stage Ⅱ and 186 were stage Ⅲ. Among stage Ⅱ patients, the median recurrence-free survival (RFS) in the PD-1 monoclonal antibody group (46 cases) did not reach, while the median RFS in the IFN/OBS group (64 cases) was 36 months. The 1-year RFS rates were 85.3% and 92.1% and the 2-year RFS rates were 71.9% and 63.7% in the PD-1 monoclonal antibody group and the IFN/OBS group, respectively, with no statistically significant difference (P=0.394). Among stage Ⅲ patients, the median RFS rates in the PD-1 monoclonal antibody group (118 cases) and the IFN/OBS group (68 cases) were 23 and 13 months, respectively. The 1-year RFS rates were 70.0% and 51.8% and the 2-year RFS rates were 51.8% and 35.1%in the PD-1 monoclonal antibody group and the IFN/OBS group, respectively, with a statistically significant difference (P=0.010). Stratified analysis showed that the advantage of PD-1 monoclonal antibody adjuvant therapy in improving RFS persisted in the subgroups of primary ulceration (HR=0.558, 95% CI: 0.348-0.893), lymph node macroscopic metastasis (HR=0.486, 95% CI: 0.285-0.828), stage ⅢC (HR=0.389, 95% CI: 0.24-0.63), and the subgroup without BRAF/c-Kit/NRAS gene mutations (HR=0.347, 95% CI: 0.171-0.706). In terms of recurrence patterns, in stage Ⅱ patients, the recurrence and metastasis rate was 15.2% (7/46) in the PD-1 monoclonal antibody group, significantly lower than the IFN/OBS group [43.8% (28/64), P=0.002]. In stage Ⅲ melanoma patients, the recurrence and metastasis rate was 42.4% (50/118) in the PD-1 monoclonal antibody group, also lower than the IFN/OBS group [63.2% (43/68), P=0.006]. Conclusions: In real-world settings, compared with patients receiving low-dose IFN adjuvant therapy or observational follow-up, PD-1 monoclonal antibody immunotherapy can reduce the recurrence and metastasis rate of cutaneous and limb melanoma, and prolong the postoperative RFS of stage Ⅲ cutaneous and limb melanoma patients. Patients with a heavier tumor burden benefit more from immunotherapy.

AIM:To evaluate the therapeutic efficacy of intravitreal injections of ranibizumab for macular edema secondary to retinal vein occlusion(RVO)and the prognostic factors for this disorder.METHODS:A retrospective case study. There were 61 patients(61 eyes)with macular edema secondary to RVO who treated in our hospital from April 2020 to February 2021, including 30 cases(30 eyes)of branch retinal vein occlusion(BRVO)patients and 31 cases(31 eyes)of central retinal vein occlusion(CRVO)patients. All patients received 3 times of intravitreal injections of ranibizumab(0.5mg), and some eyes underwent retinal laser therapy. The patients were followed up for 3mo after treatment(the first intravitreal injection)to observe the visual acuity, intraocular pressure, central retinal thickness(CRT)and record the occurrence of ocular and systemic complications.RESULTS: The visual acuity of the included patients after treatment was significantly improved compared with that before treatment, and the CRT was significantly decreased compared with that before treatment(P<0.01), and after 3 times of intravitreal injections, the visual acuity of BRVO and CRVO patients with pre-treatment visual acuity≤1(LogMAR)was better than that of the patients with pre-treatment visual acuity>1(P<0.01), but there was no difference in CRT(all P >0.05). Among BRVO and CRVO patients, 12 and 8 eyes received retinal laser treatment during 3 times of intravitreal injections, respectively. The difference in visual acuity and CRT among the eyes treated with laser and those that were untreated was not significant(P>0.05). No ocular and systemic serious complications emerged during follow-up.CONCLUSIONS: Ranibizumab has high efficacy and safety in the treatment of macular edema secondary to RVO, while visual acuity at baseline may help predict the prognosis.

Objective:To investigate the situation of patients with human immunodeficiency virus (HIV) infection who re-engaging treatment after dropping-out during anti-retroviral therapy (ART), and the influencing factors of ART re-engagement in Yunnan Province.Methods:The total dropping-out cases of ART up to December 31, 2018, including cases of lost-of-follow-up and withdrawing medications in Yunnan Province were included. The status of drop-out and demographic data were collected from survey questionnaires and the extracted medical-visiting records from the China National Free Antiretroviral Treatment Program Database of Chinese Center for Disease Control and Prevention. Chi-square test was used in statistical analysis and logistic regression was applied in analyzing factors related with re-engagement.Results:Among the total 6 075 cases with HIV infection which were recorded with the status of drop-out during ART in Yunnan Province, 5 340(87.9%) cases were confirmed drop-out, 540(8.9%) cases were false dropping-out due to belated medical visiting records, 109(1.8%) cases provided invalid answers or had no response to survey questionnaire, and 86(1.4%) cases failed to report results. Among 5 340 confirmed drop-out cases, the findings showed that 923(17.3%) cases were tracked and successfully re-initiated ART, 2 327(43.6%) cases could not be contacted, 1 443(27.0%) cases refused ART, 100(1.9%) cases died, 39(0.7%) cases came back for treatment by self-willing, 91(1.7%) cases were detained, and 417(7.8%) cases were in other situations. Tracking the dropping-out cases were through the workers based on the health facilities including ART clinics, centers for disease control and prevention and the community-based organizations. They tracked the dropping-out cases by phone, through household visiting or face-to-face communication. Statistically significant differences were found in the proportion of patients re-engagement by gender, re-engagement age, route of infection, education level and time from entry to last loss ( χ2=6.14, 21.26, 8.24, 17.69, 12.75, respectively, all P<0.050). The logistic regression suggested that the protective factors related with the re-engagement included female (adjusted odds ratio (a OR)=1.34, 95% confidence interval ( CI) 1.12 to 1.61, P=0.002), re-engagement age≤30 year-old (a OR=1.78, 95% CI 1.25 to 2.55, P<0.001), age of 31 to 60 year-old (a OR=1.33, 95% CI 1.01 to 1.76, P=0.043), education level with primary school to high school or technical secondary school (a OR=1.56, 95% CI 1.21 to 2.01, P<0.001), the period>24 months between first initiating ART and dropping-out (a OR=1.37, 95% CI 1.11 to 1.70, P=0.004). Conclusions:The program of tracking and re-engagement for ART dropping-out patients in Yunnan Province needs multi-department participation and investing large resources, but the success rate of tracking and re-engagement is not high. The protective factors related with re-engagement are female, re-engagement age≤60 year-old, education level with primary school to high school or technical secondary school, the period>24 months between first initiating ART and dropping-out.
