ObjectiveTo reveal the mechanism of Zuogui Jiangtang Jieyu prescription against damage to hippocampal synaptic microenvironment via suppressing glutamate receptor 2 （GluR2）/Parkin signal-mediated mitophagy in rats with diabetes-related depression （DD）. MethodsEighty male SD rats underwent adaptive feeding for 5 days before the study. Ten rats were randomly assigned to the normal group. The model of DD rats was established with the rest by 2-week high-fat diet + streptozotocin （STZ） tail intravenous injection + 28 days of chronic unpredictable mild stress （CUMS） combined with isolation. The rats were randomly divided into a normal group， a model group， a GluR2 blocker group （5 μg·kg^-1）， a GluR2 agonist group （10 μg·kg^-1）， a metformin + fluoxetine group （0.18 g·kg^-1 metformin + 1.8 mg·kg^-1 fluoxetine）， and high- and low-dose Zuogui Jiangtang Jieyu prescription groups （20.52 and 10.26 g·kg^-1， respectively）. The rats in the GluR2 blocker group and the GluR2 agonist group were continuously injected with CNQX and Cl-HIBO in the dentate gyrus of the hippocampus once a week starting from stress modeling， respectively， while the metformin + fluoxetine group and the high- and low-dose Zuogui Jiangtang Jieyu prescription groups were continuously given intragastric administration for 28 d at the same time of stress modeling. Depression-like behavior was evaluated by open field and forced swimming experiments. The levels of serum insulin and adenosine triphosphate （ATP） in hippocampus were detected by biochemical analysis. The levels of 5-hydroxytryptamine （5-HT） and dopamine （DA） in hippocampus were detected by enzyme-linked immunosorbent assay （ELISA）. The autophagosomes of hippocampal neurons were observed by transmission electron microscopy. The morphology and structure of dendrites and spines of hippocampal neurons were evaluated by Golgi staining. Western blot detected the expression levels of GluR2 and Parkin proteins in hippocampus. The expression levels of GluR2， Parkin， regulating synaptic membrane exocytosis protein 3 （RIMS3）， and postsynaptic density protein 95 （PSD95） in the dentate gyrus of the hippocampus were detected by immunofluorescence. ResultsCompared with the normal group， the model group exhibited reduced total activity distance in the open field and increased immobility time in forced swimming （P<0.01）， lowered levels of serum insulin and ATP， 5-HT， and DA in hippocampus （P<0.01）， increased autophagosomes of hippocampal neurons， significantly damaged morphology and structure of dendrites and spines of hippocampal neurons， decreased expression levels of GluR2， RIMS3， and PSD95 in hippocampus， and an increased Parkin expression level （P<0.05， P<0.01）. Compared with the model group， the GluR2 blocker group and the GluR2 agonist group showed aggravation and alleviation of the above abnormal changes， respectively （P<0.05， P<0.01）. The above depression-like behavior was significantly improved in the high- and low-dose Zuogui Jiangtang Jieyu prescription groups to different degrees. Specifically， the two groups saw elevated levels of serum insulin and ATP， 5-HT， and DA in hippocampus （P<0.05， P<0.01）， restrained increase in autophagosomes and damage to morphology and structure of dendrites and spines of hippocampal neurons， up-regulated protein expression levels of GluR2， RIMS3， and PSD95， and down-regulated Parkin expression level （P<0.05， P<0.01）. ConclusionZuogui Jiangtong Jieyu prescription can ameliorate the mitophagy-mediated damage to hippocampal synaptic microenvironment in DD rats， the mechanism of which might be related to the regulation of GluR2/Parkin signaling pathway.

Clinical data of a patient with alveolar soft part sarcoma (ASPS) treated at Zhongshan Hospital, Fudan University were retrospectively analyzed. The patient was initially diagnosed with abdominal ASPS with multiple lung metastases. After 6 weeks of treatment with nivolumab and ipilimumab, the patient achieved stable disease (SD). In the 7th week, the treatment was changed to a combination of nivolumab (30 mg, d1, q3w), anlotinib (8 mg, d1-14, q3w) and ipilimumab (50 mg, d1, q6w). The patient remained SD at the 12th week. The patient then underwent iliac artery embolization and intensity-modulated radiation therapy for the lesion in the psoas major muscle, while continuing the combination treatment. By the 24th week, the evaluation showed partial remission (PR) of both primary tumor and lung metastases. The patient experienced mild adverse reactions during treatment.

ObjectiveTo explore and verify the key pathway of Zuogui Jiangtang Jieyu prescription in the treatment of diabetes with depression by means of gene set enrichment analysis （GSEA） and short time-series expression miner （STEM）. MethodSD rats were randomly divided into six groups， including a normal group， a model group， high， medium， and low dose groups of Zuogui Jiangtang Jieyu prescription， and a positive drug group. The model of diabetes with depression was established by high-fat feeding， streptozotocin （STZ） injection， and chronic mild unpredictable stress. The high， medium， and low dose groups of Zuogui Jiangtang Jieyu prescription were orally administered at 20.52， 10.26， and 5.13 g·kg^-1 respectively. The positive drug group was orally administered 0.18 g·kg^-1 metformin and 1.8 g·kg^-1 fluoxetine. The rats in the normal group and model group were administered with an equal volume of distilled water. After 28 days， the animals were tested for depressive-like behaviors and cognitive function using the forced swimming test and Morris water maze. Fasting blood glucose was measured using blood glucose test strips. Cholesterol and triglyceride levels were measured using enzyme-linked immunosorbent assay （ELISA）. Three hippocampus samples were randomly selected from the normal group， the model group， the high dose group of Zuogui Jiangtang Jieyu prescription for high-throughput transcriptome sequencing. Differential gene analysis， GSEA analysis， and STEM analysis were used to screen the key pathways and target genes of Zuogui Jiangtang Jieyu prescription in the treatment of diabetes with depression. Key target genes were validated using real-time fluorescence quantitative PCR （Real-time PCR）. The expression of the signal protein mediated by the target genes was detected by Western blot. ResultCompared with the results in the normal group， the fasting blood glucose， cholesterol， and triglyceride levels in the model group were significantly increased （P<0.01）. Moreover， the immobility time in the forced swimming test was significantly increased， while the time to climb the platform was significantly prolonged， and the search distance in the target quadrant was significantly reduced in the Morris water maze test （P<0.05，P<0.01）. Compared with the model group， the high dose of Zuogui Jiangtang Jieyu prescription significantly reduced the levels of blood glucose， cholesterol， and triglycerides in rats with diabetes with depression （P<0.05，P<0.01）， reduced the immobility time in the forced swimming test， shortened the stage time in the Morris water maze test， and increased the search distance ratio in the target area （P<0.05，P<0.01）. Transcriptome sequencing differential analysis showed that the normal group had 1 366 differentially expressed genes compared to the model group， while the model group had 1 149 differentially expressed genes compared to the high dose group of Zuogui Jiangtang Jieyu prescription， with 581 intersecting genes. The GSEA results showed that there were 9 sets of differentially expressed genes between the normal group and the model group， and 43 sets of differentially expressed genes between the model group and the high dose group of Zuogui Jiangtang Jieyu prescription， with 7 intersecting gene sets. STEM analysis showed that according to the analysis order of the normal group， model group， and high dose group of Zuogui Jiangtang Jieyu prescription， two significantly different trend clustering groups were obtained. One key gene set for axonal guidance， as well as key target signal elements Sema3c， Sema7a， Robo3， Epha8， and Epha7， were identified through synthesizing the three analysis results. Real-time PCR validated that compared with the results in the normal group， the mRNA expression of Robo3， Sema7a， and Epha7 in the hippocampus of the model rats was significantly reduced （P<0.05， P<0.01）. Compared with the model group， the high dose of Zuogui Jiangtang Jieyu prescription significantly increased the mRNA expression of Robo3， Sema7a， and Epha7 （P<0.05， P<0.01）. Western blot results showed that compared with the results in the normal group， the Sema7a， ITGB1， and FAK protein expression in the hippocampus of the model group was significantly reduced （P<0.01）. Compared with the model group， the high dose of Zuogui Jiangtang Jieyu prescription significantly increased the protein expression of Sema7a， ITGB1， and FAK in the hippocampus （P<0.05，P<0.01）. ConclusionZuogui Jiangtang Jieyu prescription may treat diabetes with depression by regulating axonal guidance based on the Sema7a/ITGB1 signaling pathway.

Objective:To assess the effectiveness of a 6-month Ba Duan Jin exercise program in improving the balance of community-dwelling older adults.Methods:A two arms, parallel-group, cluster randomized controlled trial was conducted in 1 028 community residents aged 60-80 years in 40 communities in 5 provinces of China. Participants in the intervention group (20 communities, 523 people) received Ba Duan Jin exercise 5 days/week, 1 hour/day for 6 months, and three times of falls prevention health education, and the control group (20 communities, 505 people) received falls prevention health education same as the intervention group. The Berg balance scale (BBS) score was the leading outcome indicator, and the secondary outcome indicators included the length of time of standing on one foot (with eyes open and closed), standing in a tandem stance (with eyes open and closed), the closed circle test, and the timed up to test.Results:A total of 1 028 participants were included in the final analysis, including 731 women (71.11%) and 297 men (28.89%), and the age was (69.87±5.67) years. After the 3-month intervention, compared with the baseline data, the BBS score of the intervention group was significantly higher than the control group by 3.05 (95% CI: 2.23-3.88) points ( P<0.001). After the 6-month intervention, compared with the baseline data, the BBS score of the intervention group was significantly higher than the control group by 4.70 (95% CI: 4.03-5.37) points ( P<0.001). Ba Duan Jin showed significant improvement ( P<0.05) in all secondary outcomes after 6 months of exercise in the intervention group compared with the control group. Conclusions:This study showed that Ba Duan Jin exercise can improve balance in community-dwelling older adults aged 60-80. The longer the exercise time, the better the improvement.

ObjectiveTo explore the potential mechanism of Zuogui Jiangtang Jieyu Formula （左归降糖解郁方， ZJJF） for diabetic rats with depression. MethodsSixty rats were randomly divided into normal group， model group， wingless MMTV integration site family member 5a （Wnt5a） agonist group， ZJJF group， and ZJJF plus Wnt5a inhibitor group， with 12 rats in each group. Except for the normal group， the rats were fed with high-fat chow， streptozotocin injection， and chronic mild unpredictable stress combination， to establish model of diabetes mellitus complicated with depression. After successful modelling， rats in the Wnt5a agonist group were given bilateral hippocampal stereotactic injections of Wnt5a agonist Foxy-5 with 5 μl each for 7 consecutive days； rats in ZJJF group were given 20.52 g/（kg·d） of ZJJF by gavage； rats in ZJJF plus Wnt5a inhibitor group were given the drug by gavage， and bilateral hippocampal stereotactic injections of Wnt5a inhibitors Box5， with the same dosage and injection method as above. The normal group and model group were given 10 ml/（kg·d） of normal saline by gavage. All groups were gavaged for 4 consecutive weeks. At the end of the intervention， the depression-like behaviour of rats was evaluated using the forced swimming experiment （immobility time） and the absent field experiment （number of activities）； the blood glucose and insulin levels of rats were measured and the insulin resistance index was calculated； the dendritic morphology of dentate gyrus neurons in the hippocampus was observed using Golgi staining； the level of dentate gyrus neuron proliferation was measured using 5-bromodeoxyuracil nucleoside （Brdu） injection and immunofluorescence； RT-qPCR and Western blot were used to detect the mRNA and protein expression of Wnt5a， Ras homologue genomic member A （RhoA） and Rho homologue-associated coiled-coil protein kinase 1 （ROCK1） in the dentate gyrus. ResultsCompared with the normal group， rats in the model group had significantly higher blood glucose， insulin and insulin resistance indices， longer immobility time， fewer activities， lower Brdu integral optical density values and Wnt5a， RhoA， ROCK1 protein and mRNA expression in the dentate gyrus of the hippocampus （P＜0.05 or P＜ 0.01）； the dendritic branches of rat hippocampal dentate gyrus neurons could be seen to be significantly reduced or broken， and their length shortened. Compared with the model group， the blood glucose， insulin and insulin resistance indices of rats in ZJJF group and the ZJJF plus Wnt5a inhibitor group significantly reduced （P＜0.05 or P＜0.01）； the immobility time of rats in the Wnt5a agonist group and ZJJF group was significantly shortened， the number of activities increased， the Brdu integral optical density values elevated， and the Wnt5a， RhoA， ROCK1 protein and mRNA expression elevated （P＜0.05 or P＜0.01）， and the number of dendritic branches of hippocampal dentate gyrus neurons significantly increased， the length lengthened， and the complexity of dendrites increased. Compared with the Wnt5a agonist group， rats in the ZJJF group showed significant decrease in blood glucose， insulin and insulin resistance indices， prolongation of immobilisation time， reduction in the number of activities， and reduction in the Brdu integral optical density value； except for the Wnt5a mRNA in ZJJF group， Wnt5a， RhoA， ROCK1 protein and mRNA expression reduced in both ZJJF group and ZJJF plus Wnt5a inhibitor group （P＜0.05 or P＜0.01）. Compared with ZJJF group， Wnt5a， RhoA， ROCK1 protein and mRNA expression were reduced in ZJJF plus Wnt5a inhibitor group （P＜0.05 or P＜0.01）. ConclusionZJJF can improve hyperglycemia and depressive-like behaviours in rat models of diabetes with depression， and its antidepressant effects may be related to the activation of hippocampal Wnt5a/RhoA signaling and promotion of dentate gyrus neuron dendritic growth.

Objective:To analyze the safety and efficacy of PD-1 inhibitors versus chemotherapy or ipilimumab in advanced melanoma.Methods:PubMed,CNKI,VIP and Wanfang databases were searched to collect randomised controlled trials of PD-1 inhibi-tors in treatment of advanced melanoma.The search time was from the establishment of the database to May 1,2022.Two reviewers independently screened the literature,extracted data,and assessed risk of bias of included studies.Meta-analysis was performed using RevMan5.4 and STATA16 software.Results:A total of 7 studies were included.Meta-analysis results show that:①Safety:Compared with chemotherapy,PD-1 inhibitor treatment had fewer adverse events,especially in the blood system;compared with ipilimumab alone,PD-1 inhibitor combined with ipilimumab had more adverse events,especially liver function indicators;there was no signifi-cant difference in the incidence of total adverse events between PD-1 inhibitor monotherapy and ipilimumab monotherapy.②Efficacy:The PFS,OS and ORR of PD-1 inhibitor versus chemotherapy or ipilimumab were HR=0.54,95%CI(0.45,0.62),P<0.05,HR= 0.69,95%CI(0.58,0.80),P=0.03 and OR=3.16,95%CI(2.59,3.86),P<0.05,respectively.Conclusion:PD-1 inhibitors have good efficacy in treatment of advanced melanoma,while different combination methods and different control treatments may have different efficacy.Limited by the quantity and quality of included studies,more research evidence is needed to support this.

Objective:To analyze the clinical characteristics and outcomes of patients with invasive fungal sinusitis (invasive fungal rhinosinusitis, IFR) after allogeneic hematopoietic stem cell transplantation (allo-HSCT) and explored the risk factors for IFR after allo-HSCT.Methods:Nineteen patients with IFR after allo-HSCT at Peking University People’s Hospital from January 2012 to December 2021 were selected as the study group, and 95 patients without IFR after allo-HSCT during this period were randomly selected as the control group (1:5 ratio) .Results:Nineteen patients, including 10 males and 9 females, had IFR after allo-HSCT. The median age was 36 (10–59) years. The median IFR onset time was 68 (9–880) days after allo-HSCT. There were seven patients with acute myeloid leukemia, five with acute lymphoblastic leukemia, two with myelodysplastic syndrome, two with chronic myeloid leukemia, one with acute mixed-cell leukemia, one with multiple myeloma, and one with T-lymphoblastic lymph node tumor. There were 13 confirmed cases and 6 clinically diagnosed cases. The responsible fungus was Mucor in two cases, Rhizopus in four, Aspergillus in four, and Candida in three. Five patients received combined treatment comprising amphotericin B and posaconazole, one patient received combined treatment comprising voriconazole and posaconazole, nine patients received voriconazole, and four patients received amphotericin B. In addition to antifungal treatment, 10 patients underwent surgery. After antifungal treatment and surgery, 15 patients achieved a response, including 13 patients with a complete response and 2 patients with a partial response. Multivariate analysis revealed that neutropenia before transplantation ( P=0.021) , hemorrhagic cystitis after transplantation ( P=0.012) , delayed platelet engraftment ( P=0.008) , and lower transplant mononuclear cell count ( P=0.012) were independent risk factors for IFR after allo-HSCT. The 5-year overall survival rates in the IFR and control groups after transplantation were 29.00%±0.12% and 91.00%±0.03%, respectively ( P<0.01) . Conclusion:Although IFR is rare, it is associated with poor outcomes in patients undergoing allo-HSCT. The combination of antifungal treatment and surgery might be effective.

Objectives:To determine the effect of glucose-6-phosphate-dehydrogenase (G6PD) deficiency on patients’ complications and prognosis following allogeneic stem cell hematopoietic transplantation (allo-HSCT) .Methods:7 patients with G6PD deficiency (study group) who underwent allo-HSCT at Peking University People's Hospital from March 2015 to January 2021 were selected as the study group, and thirty-five patients who underwent allo-HSCT during the same period but did not have G6PD deficiency were randomly selected as the control group in a 1∶5 ratio. Gender, age, underlying diseases, and donors were balanced between the two groups. Collect clinical data from two patient groups and perform a retrospective nested case-control study.Results:The study group consisted of six male patients and one female patient, with a median age of 37 (range, 2-45) years old. The underlying hematologic diseases included acute myeloid leukemia ( n=3), acute lymphocytic leukemia ( n=2), and severe aplastic anemia ( n=2). All 7 G6PD deficiency patients achieved engraftment of neutrophils within 28 days of allo-HSCT, while the engraftment rate of neutrophils was 94.5% in the control group. The median days of platelet engraftment were 21 (6–64) d and 14 (7–70) d ( P=0.113). The incidence rates of secondary poor graft function in the study group and control group were 42.9% (3/7) and 8.6% (3/35), respectively ( P=0.036). The CMV infection rates were 71.4% (5/7) and 31.4% (11/35), respectively ( P=0.049). The incidence rates of hemorrhagic cystitis were 57.1% (4/7) and 8.6% (3/35), respectively ( P=0.005), while the bacterial infection rates were 100% (7/7) and 77.1% (27/35), respectively ( P=0.070). The infection rates of EBV were 14.3% (1/7) and 14.3% (5/35), respectively ( P=1.000), while the incidence of fungal infection was 14.3% (1/7) and 25.7% (9/35), respectively ( P=0.497). The rates of post-transplant lymphoproliferative disease (PTLD) were 0% and 5.7%, respectively ( P=0.387) . Conclusions:The findings of this study indicate that blood disease patients with G6PD deficiency can tolerate conventional allo-HSCT pretreatment regimens, and granulocytes and platelets can be implanted successfully. However, after transplantation, patients should exercise caution to avoid viral infection, complications of hemorrhagic cystitis, and secondary poor graft function.

Objective:To evaluate the abnormal changes in the liver stiffness (LS) in the pregnant women with or without hypertensive disorder of pregnancy (HDP) using conventional ultrasound and two-dimensional shear wave ultrasound elastography (2D-SWE).Methods:A total of 73 pregnant women were enrolled and diagnosed in the Second Affiliated Hospital of Dalian Medical University from May to September 2023. They were divided into pregnant women without HDP (group A, 36 cases), and pregnant women with HDP (group B, 37 cases). Another 36 healthy volunteers were enrolled in the control group (group C). The thickness and length of the left lobe of the liver, the maximum oblique diameter of the right lobe of the liver and the diameter of the main trunk of the portal vein were measured with two-dimensional ultrasound. The velocity of the portal vein was measured with pulse wave Doppler. 2D-SWE technique was used to measure LS (E mean). Parameters were compared among the groups. Results:The right hepatic oblique diameters in groups A and B were larger than those in group C: 13.87 (0.54) cm and 13.95 (0.36) cm vs. 13.56 (1.02) cm (all P<0.01), but there was no significant difference in the right hepatic oblique diameter between group A and group B ( P>0.05). E mean in both group A and group B were greater than those in group C: 5.02 (0.62) kPa and 5.99 (0.31) kPa vs. 4.76 (0.08) kPa ( P<0.01). E mean in group B was greater than that in group A ( P<0.05). Systolic and diastolic blood pressure were independent impact factors of Emean ( P<0.05). E mean and diastolic blood pressure were independent impact factors of HDP ( P<0.05). Conclusions:2D-SWE technique could be used to accurately, objectively and non-invasively evaluate abnormal the changes of liver stiffness in patients with HDP.
