ObjectiveTo explore the effect of exercise on anxiety and depression in cancer patients during chemotherapy, as well as the optimal exercise dosage. MethodsA PICO framework was constructed, and randomized controlled trials (RCTs) on the effect of exercise on anxiety and depression in cancer patients during chemotherapy were retrieved from databases of PubMed, Web of Science, Cochrane Library, Embase, Medline, CNKI, VIP and Wanfang data, from the establishment to November, 2023. The quality of the literature was evaluated with Cochrane Risk of Bias Tool and Physiotherapy Evidence Database (PEDro) scale. Data were synthesized and analyzed using RevMan 5.3, and the risk of bias was evaluated using Stata 18.0. ResultsA total of 13 RCTs involving 1 340 subjects were included. The scores of PEDro scale were five to eight. Exercise interventions significantly improved anxiety (SMD = -0.70, 95%CI -1.18 to -0.22, P = 0.004) and depression (SMD = -0.89, 95%CI -1.43 to -0.34, P = 0.002) compared to the control group. Subgroup analyses showed that, the exercise effect on anxiety was less than 45 minutes a time (SMD = -0.26, 95%CI -0.46 to -0.05, P = 0.01), more than three times a week (SMD = -0.26, 95%CI -0.46 to -0.05, P = 0.01), and less than twelve weeks (SMD = -0.21, 95%CI -0.36 to -0.07, P = 0.005). For depression, it was less than 45 minutes a time (SMD = -0.69, 95%CI -1.29 to -0.08, P = 0.03), more than three times a week (SMD = -0.69, 95%CI -1.29 to -0.08, P = 0.03), and less than twelve weeks (SMD = -0.52, 95%CI -0.92 to -0.13, P = 0.01). Moderate to high-intensity exercise interventions significantly outperformed the control group in improving anxiety (SMD = -0.21, 95%CI -0.37 to -0.06, P = 0.007) and depression (SMD = -0.21, 95%CI -0.41 to -0.01, P = 0.04). ConclusionExercise interventions can effectively improve anxiety and depression in cancer patients during chemotherapy, and it suggests for high-intensity exercise, less than 45 minutes a time, more than three times a week, and less than twelve weeks.

ObjectiveTo observe the clinical efficacy and safety of Zhuyuwan in the treatment of hyperlipidemia. MethodsIn this study， hyperlipidemia patients treated in the Hospital of Chengdu University of Traditional Chinese Medicine （TCM） from September 2022 to December 2023 were randomly assigned into a control group and an observation group. Finally， 162 valid cases were included， encompassing 74 cases in the control group and 88 cases in the observation group. The control group was treated with atorvastatin calcium tablets， and the observation group with atorvastatin calcium tablets + Zhuyuwan extract granules. Both groups were treated for 8 weeks. The efficacy in terms of blood lipid level recovery， blood lipid levels， TCM syndrome distribution， efficacy in terms of TCM syndrome， and TCM symptom scores were compared between the two groups as well as between before and after treatment. Liver and kidney functions were monitored for safety assessment. ResultsIn terms of blood lipid level recovery， the total response rate in the observation group was 86.36% （76/88） and that in the control group was 86.49% （64/74）， with no statistically significant difference between the two groups. After treatment， both groups showed declines in levels of triglyceride （TG）， total cholesterol （TC）， and low-density lipoprotein cholesterol （LDL-C） （P<0.05） and elevations in the level of high-density lipoprotein cholesterol （HDL-C） （P<0.05）. Moreover， the observation group outperformed the control group in recovering the levels of TG， LDL-C， and HDL-C （P<0.05， P<0.01）. In terms of TCM syndrome， hyperlipidemia was mostly caused by phlegm turbidity and obstruction. The total response rate in terms of TCM syndrome in the observation group was 87.30% （55/63）， which was higher than that （63.46%， 33/52） in the control group （χ²=9.102， P<0.01）. After treatment， the scores of total TCM symptoms， primary symptoms， and secondary symptoms decreased in both groups （P<0.05）， and the observation group had lower scores than the control group （P<0.01）. The observation group was superior to the control group in alleviating obesity， chest tightness， and low food intake （P<0.05）. In terms of safety， the level of aminotransferase was slightly elevated in the control group， and no obvious adverse reaction was observed in the observation group， with no statistical significance in the incidence of adverse reactions. ConclusionZhuyuwan combined with atorvastatin can not only recover blood lipid levels and alleviate TCM symptoms but also reduce the occurrence of adverse reactions.

Objective To report the diagnosis of a canine distemper virus outbreak among a colony of cynomolgus monkeys at an experimental monkey farm in 2019. MethodsA total of 46 samples were collected from 21 diseased cynomolgus monkeys (exhibiting symptoms such as facial rash, skin scurf, runny nose, and diarrhea) and from one deceased monkey at an experimental monkey breeding farm in South China in late 2019, including serum, skin rash swabs, and anticoagulated whole blood, liver, lung, and skin tissues were submitted for testing. All submitted samples were tested for canine distemper virus gene fragments using real-time quantitative PCR, while immunohistochemical staining was performed to detect canine distemper virus nucleoprotein in lung tissues. The skin tissue of the deceased monkey was ground and sieved. The filtrate was inoculated into a monolayer MDCK cell line for virus isolation. Then, whole-genome sequencing was performed to identify the isolated virus. The Clustal Omega tool was used to align and analyze the homology of different Asian canine distemper virus isolates. A phylogenetic tree was constructed, followed by genetic evolutionary analysis. ResultsClinical retrospective analysis revealed that the diseased cynomolgus monkeys exhibited symptoms similar to those observed in cynomolgus monkeys infected with measles virus. Necropsy findings showed red lesions in the lungs and significant hemorrhage in the colonic mucosa. Real-time quantitative PCR detected canine distemper virus nucleic acid in the serum, skin rash swabs of the infected monkeys, and various tissue samples of the deceased monkey, all of which tested positive. Calculation based on the standard curve formula indicated the viral load was highest in the skin tissue. Immunohistochemical staining of the deceased monkey's lung tissue demonstrated aggregation of CDV nucleoprotein in alveolar epithelial cells, bronchi, and bronchioles. A CDV strain was isolated from the skin tissue of the deceased monkey. Phylogenetic analysis indicated that this strain shares the closest relationship (98.86%) with the Asian-1 type canine distemper virus strain CDV/dog/HCM/33/140816, previously identified in dogs in Vietnam. ConclusionBased on comprehensive analysis of clinical symptoms, nucleic acid detection, viral protein immunohistochemistry, and whole-genome sequencing results, the diagnosis confirms that the cynomolgus monkeys in this facility are infected with canine distemper virus. It is recommended to include canine distemper virus as a routine surveillance target in captive monkey populations. Additionally, this study provides a foundation for further research on the molecular biological characteristics of canine distemper virus.

Objective:To explore the changes in serum indoleamine 2, 3-dioxygenase (IDO) and kynurenic acid (KYNA) levels in preterm infants diagnosed with bronchopulmonary dysplasia (BPD).Methods:A nested case-control study was conducted. The inclusion criteria covered premature infants with less than 32 weeks of gestational age within 24 h post-birth, from December 1, 2021, to December 31, 2022, at Children's Hospital of Soochow University. Those diagnosed with BPD were allocated to the BPD group ( n=35). Non-BPD preterm infants matching the BPD cases in terms of gestational age (within one week difference) and birth weight (within a 150 g difference) were selected in a 1∶1 ratio for the control group ( n=35). Serum levels of IDO and KYNA were measured on days 1, 7, 14, and 28 postnatally. Differences in serum IDO and KYNA levels were analyzed between the BPD and control groups and among infants with mild BPD versus moderate-to-severe BPD. The association between serum IDO and KYNA levels with the severity of BPD was also assessed. Statistical analysis was conducted using independent samples t-tests and Spearman's correlation analysis. Results:Elevated levels of serum IDO on days 7, 14, and 28 postnatally [(60.68±9.37) vs. (50.66±10.46), (57.81±11.07) vs. (44.45±8.20), and (50.62±10.77) vs. (41.31±7.74) pg/ml; t=4.21, 5.73, and 4.15, respectively] as well as increased serum KYNA levels on days 14 and 28 [(439.31±41.22) vs. (368.99±68.79), (376.97±45.74) vs. (325.50±60.07) μmol/L; t=5.18 and 4.03, respectively] were observed in the BPD group compared to the control group, with all differences being statistically significant (all P<0.05). Furthermore, positive correlations were observed between serum IDO levels and BPD severity on the 7th, 14th, and 28th days ( r=0.546, 0.495, and 0.502, all P<0.05), as well as between serum KYNA levels and BPD severity on the 14th and 28th days ( r=0.536 and 0.458, both P<0.05). Conclusion:Elevated serum levels of IDO and KYNA in infants with BPD suggest these metabolites may play a role in the pathogenesis and progression of BPD.

Objective:To investigate the expression of hippocampal synapse-related proteins including synaptophysin (SYN), postsynaptic density protein 95 (PSD95) and growth-associated protein 43 (GAP43) in rats with epilepsy accompanied by depression.Methods:The 3-month-old female clean grade SD rats were selected for the experiment.Lithium chloride pilocarpine was used to establish an epileptic rat model. Rats with successful epilepsy models were divided into epileptic depressive group (EWD group)and epileptic group with 10 in each group based on whether they were accompanied by depression. Furthermore, ten rats with matched body mass were taken as the depressive group and 10 were taken as control group. As for the depressive group rats, chronic unpredictable mild stress stimulation combined with orphanage was adopted to establish a model of depression.The depressive behaviors of rats were evaluated by body mass, sucrose preference test and open field test. Immunohistochemical staining and Western blot were used to detect the expression of SYN, PSD95 and GAP43 proteins in rat hippocampal tissue. SPSS 17.0 software was used for data statistical analysis, repeated measurement ANOVA was used for behavioral results, one-way ANOVA was used for inter group comparison of protein expression data, and LSD test was used for further pairwise comparison.Results:As for the body mass, there was significant interaction effect between the time and group among the 4 groups ( F=7.33, P<0.01). On the 8th day and the 29th day, the body weight of rats in the EWD group and the depressive group were lower than those in the epilepsy group (all P<0.05). The body weight of rats in the EWD group on the 29th day was lower than that on the first day ( P<0.05). As for the sucrose preference rates, there was significant interaction effect between the time and group among the 4 groups( F=2.67, P<0.05). The sucrose preference rate of EWD group on the15th and 29th day were lower than that on the first day (both P<0.05). The results of the open field test showed that the interaction effects of the number of vertical standing times( F=2.74) and the number of horizontal movement lattices ( F=1.76) both were not significant (both P>0.05), but both the time effect and group effect were significant (vertical standing times: Ftime=4.35, P<0.05, Fgroup=25.64, P<0.01; horizontal movement lattices: Ftime=12.75, P<0.01, Fgroup=21.37, P<0.01). The immunohistochemical results showed that there was a statistically significant difference in the number of positive cells expressing synaptic proteins SYN, PSD95 and GAP43 among the four groups of rats ( F=93.85, 58.66, 98.84, all P<0.05). The numbers of positive cells of SYN (11.73±4.30), PSD95 (24.47±7.58) and GAP43 (9.40±3.50) in the epilepsy group were lower than those in the control group ((51.00±15.39), (55.60±13.17) and (29.53±4.05)) (all P<0.05). The numbers of positive cells of SYN (5.80±3.53), PSD95 (12.87±4.03) and GAP43 (5.33±3.50) in the EWD group were lower than those in the depressive group ((11.33±3.22), (48.13±12.69) and (15.47±5.21) )(all P<0.05). Western blot results showed that there were statistically significant differences in the expression of synaptic proteins SYN, PSD95 and GAP43 among the four groups of rats ( F=13.19, 9.38, 16.80, all P<0.05). The expression levels of SYN, PSD95 and GAP43 in the epilepsy group were lower than those in the control group (all P<0.05). The expression levels of SYN, PSD95 and GAP43 in the EWD group were lower than those in the epilepsy group and the depressive group (all P<0.05). Conclusion:The low expression of SYN, PSD95 and GAP43 proteins in the hippocampus of rats with epilepsy accompanied by depression may be related to their pathogenesis.

Objective:To analyse the clinical features and prognosis of pertussis in neonates and infants.Methods:The clinical data of neonates and infants with pertussis hospitalized in Children′s Hospital of Soochow University from September 2021 to September 2022 were retrospectively analyzed and grouped in terms of age, the severity of the disease, and whether a mixed infection, respectively.Results:A total of 40 infants with pertussis were analyzed.All cases showed improvement and were discharged after receiving active anti-infective treatment.In the neonatal group, higher rates of apnea and hyponatremia were observed compared to the non-neonatal group(all P<0.05).Additionally, peripheral blood leukocyte counts[20.9(15.0, 28.7)×10 9/L vs.16.6(11.3, 21.2)×10 9/L], neutrophil counts[4.6(3.7, 7.9)×10 9/L vs.3.2(2.1, 5.3)×10 9/L], γ-glutamyltransferase levels[78.0( 50.2, 109.4)U/L vs.22.5(15.1, 38.9)U/L], duration of hospitalization[21.5(16.8, 25.0)d vs.11.5(9.0, 19.8)d], and duration of oxygen use[7.0(0, 21.0)d vs.0(0, 2.3)d]were higher in the neonatal group than in the non-neonatal group(all P<0.05).However, the IgA level[0.02(0.02, 0.04)g/L vs.0.05(0.03, 0.09)g/L]was significantly lower in the neonatal group than in the non-neonatal group( P<0.05).In the severe group, the proportion of onset age of less than 3 months, fever, wheezing, shortness of breath, cyanosis after rough cough, apnea, decreased heart rate, wet rales on lung auscultation, respiratory failure, cardiac insufficiency, hyponatremia, CRP>8 mg/L, spotty/patchy shadows in the lungs, as well as the use of gammaglobulin, cardioactive drug and invasive ventilation, were higher than those in the non-severe group(all P<0.05).Furthermore, peripheral blood leukocyte counts[21.0(15.4, 37.4)×10 9/L vs.17.5(11.8, 21.2)×10 9/L], neutrophil counts[5.6(4.0, 10.7)×10 9/L vs.3.2(2.3, 4.6)×10 9/L], neutrophil to lymphocyte ratio[(0.6±0.4) vs.( 0.3±0.2)], systemic immune-inflammation index[237.5(109.5, 424.9) vs.135.9(75.4, 190.5)], γ-glutamyltransferase level[53.2(31.6, 87.4)U/L vs.29.5(15.2, 65.0)U/L], duration of oxygen use[18.0(12.8, 22.5)d vs.0(0, 0)d], and duration of hospitalization[24.5(21.8, 31.2)d vs.12.0(9.0, 16.8)d]were higher in the severe group than those in the non-severe group(all P<0.05).However, the IgA level[0.03(0.02, 0.04)g/L vs.0.05(0.03, 0.09)g/L]was significantly lower in the severe group than in the non-severe group( P<0.05).The mixed infection group had a longer duration of hospitalization and a higher proportion of fever than the single infection group(all P<0.05). Conclusion:Early detection of infantile pertussis can be challenging.Neonates with pertussis tend to experience severe symptoms, such as apnea, hyponatremia, elevated white blood cell count, and longer duration of oxygen use.Symptoms such as fever, wheezing, shortness of breath, decreased heart rate, wet lung rales, and spotty/patchy shadows in the lungs, as well as early elevated CRP, neutrophil to lymphocyte ratio, systemic immune-inflammation index, and decreased IgA levels are indicators of disease exacerbation.In mixed infections group, there is a higher proportion of fever.

OBJECTIVE: To investigate the effectiveness of tibial transverse transport (TTT) combined with modified neurolysis in treatment of diabetic foot ulcer (DFU) through a prospective randomized controlled study. METHODS: The patients with DFU and diabetic peripheral neuropathy, who were admitted between February 2020 and February 2022, were selected as the research objects, of which 31 cases met the selection criteria and were included in the study. The patients were divided into two groups by random number table method. The 15 patients in the trial group were treated with TTT combined with modified neurolysis, and the 16 patients in the control group received treatment with TTT alone. There was no significant difference in gender, age, duration of DFU, ulcer area, Wagner classification, as well as preoperative foot skin temperature, visual analogue scale (VAS) score, ankle-brachial index (ABI), motor nerve conduction velocity (MNCV) of the common peroneal nerve, MNCV of the tibial nerve, MNCV of the deep peroneal nerve, two-point discrimination (2-PD) of heel, and cross-sectional area (CSA) of the common peroneal nerve between the two groups ( P>0.05). The time for ulcer healing, foot skin temperature, VAS scores, ABI, 2-PD of heel, and CSA of the common peroneal nerve before operation and at 6 and 12 months after operation were recorded and compared between groups. The differences in MNCV of the common peroneal nerve, MNCV of the tibial nerve, and MNCV of the deep peroneal nerve between pre-operation and 12 months after operation were calculated. RESULTS: All patients in both groups were followed up 12-24 months (mean, 13.9 months). The surgical incisions in both groups healed by first intention and no needle tract infections occurred during the bone transport phase. Ulcer wounds in both groups healed successfully, and there was no significant difference in the healing time ( P>0.05). During the follow-up, there was no ulcer recurrences. At 12 months after operation, the MNCV of the common peroneal nerve, the MNCV of the tibial nerve, and the MNCV of the deep peroneal nerve in both groups accelerated when compared to preoperative values ( P<0.05). Furthermore, the trial group exhibited a greater acceleration in MNCV compared to the control group, and the difference was significant ( P<0.05). The foot skin temperature, VAS score, ABI, 2-PD of heel, and CSA of the common peroneal nerve at 6 and 12 months after operation significantly improved when compared with those before operation in both groups ( P<0.05). The 2-PD gradually improved over time, showing significant difference ( P<0.05). The 2-PD of heel and VAS score of the trial group were superior to the control group, and the differences were significant ( P<0.05). There was no significant difference in ABI, foot skin temperature, and CSA of the common peroneal nerve between groups after operation ( P>0.05). CONCLUSION Compared with TTT alone, the TTT combined with modified neurolysis for DFU can simultaneously solve both microcirculatory disorders and nerve compression, improve the quality of nerve function recovery, and enhance the patient's quality of life.

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.
