Objective: To investigate the efficacy，safety and feasibility of regional lymph node dissection in laparoscopic radical surgery for bladder cancer under the guidance of indocyanine green fluorescence imaging. Methods: A total of 30 patients with muscle invasive bladder cancer (T2/T3NxM0) who volunteered to enter the clinical trial were randomly divided into the indocyanine green imaging guided laparoscopic regional lymph node dissection group (n=15) and the standard pelvic lymph node dissection group (n=15).The number of positive lymph nodes，operation time，intraoperative bleeding volume，incidence of lymph leakage，and tumor recurrence and metastasis rate 2-year after surgery were collected. Results: The number of positive lymph nodes was (4.20±1.66) and (4.60±1.72) respectively in the indocyanine green and standard groups，with no statistically significant difference (P>0.05).There were no statistically significant difference in the tumor recurrence and metastasis rates 2-year after surgery between the two groups (P>0.05).However，the indocyanine green group had shorter operation time，less intraoperative bleeding volume，and lower incidence of lymphatic leakage than the standard group (P<0.05). Conclusion: Indocyanine green fluorescence imaging guided laparoscopic lymph node dissection has comparable clinical efficacy to standard lymph node dissection，but with fewer complications.

Qingzao Jiufeitang is a famous classical formula for treating lung injury caused by warm and dryness， included in the Catalogue of Ancient Famous Classical Formulas（The First Batch）. By systematically organizing ancient and modern literature on this formula， this study analyzed and verified the origin， medicinal composition， original plants and processing， dosage and decoction method， efficacy and application of this formula. According to the research， Qingzao Jiufeitang was first recorded in Yimen Falyu in the Qing dynasty， and its creation was mainly inspired by the Ming dynasty physician MIAO Xiyong's idea of the moisturizing drugs with sweet flavour and cold nature. Based on the 2020 edition of the Pharmacopoeia of the People's Republic of China（hereinafter referred to as the Chinese Pharmacopoeia） and the textual research results of modern scholars on traditional Chinese herbal medicines， the botanical sources and processing methods of the herbs in this formula are basically clarified. Among them， Mori Folium， Gypsum Fibrosum， Ginseng Radix et Rhizoma， Sesami Semen Nigrum， Asini Corii Colla， Ophiopogonis Radix and Eriobotryae Folium are consistent with the 2020 edition of the Chinese Pharmacopoeia. The primary source of Glycyrrhizae Radix et Rhizoma is the dried roots and rhizomes of Glycyrrhiza uralensis， family Leguminosae， while the primary source of Armeniacae Semen Amarum is the dried mature seeds of Prunus armeniaca， family Rosaceae. It is recommended to use Gypsum Ustum， stir-fried Sesami Semen Nigrum， stir-fried Armeniacae Semen Amarum， Asini Corii Colla bead， and honey-fried Eriobotryae Folium， and the rest of the raw products. According to the conversion of ancient and modern doses， the recommended dosages are 11.19 g for Mori Folium， 9.33 g for Gypsum Fibrosum， 3.73 g for Glycyrrhizae Radix et Rhizoma， 2.61 g for Ginseng Radix et Rhizoma， 3.73 g for Sesami Semen Nigrum， 4.48 g for Ophiopogonis Radix， 2.61 g for Armeniacae Semen Amarum， 3.73 g for Eriobotryae Folium. The decoction method is to add 300 mL of water， decoct it down to 180 mL， remove the residue， and then add 2.98 g of Asini Corii Colla into the decoction. Take it warm after meals， two to three times a day. Qingzao Jiufeitang has the effects of clearing dryness and moistening the lungs， nourishing Yin and invigorating Qi. In ancient times， it was mainly used to treat stagnation and depression of various Qi， as well as paralysis， asthma and vomiting. In modern clinical practice， it is mostly used to treat diseases in respiratory system， otolaryngology， skin system and digestive system caused by warm-dry impairing lung， deficiency of both Qi and Yin. The above research results can provide a reference for the later development of Qingzao Jiufeitang.

BACKGROUND: While emotional distress, encompassing anxiety and depression, has been associated with negative clinical outcomes, its impact across various clinical departments and general hospitals has been less explored. Previous studies with limited sample sizes have examined the effectiveness of specific treatments (e.g., antidepressants) rather than a systemic management strategy for outcome improvement in non-psychiatric inpatients. To enhance the understanding of the importance of addressing mental health care needs among non-psychiatric patients in general hospitals, this study retrospectively investigated the impacts of emotional distress and the effects of early detection and management of depression and anxiety on hospital length of stay (LOS) and rate of long LOS (LLOS, i.e., LOS >30 days) in a large sample of non-psychiatric inpatients. METHODS: This retrospective cohort study included 487,871 inpatients from 20 non-psychiatric departments of a general hospital. They were divided, according to whether they underwent a novel strategy to manage emotional distress which deployed the Huaxi Emotional Distress Index (HEI) for brief screening with grading psychological services (BS-GPS), into BS-GPS ( n = 178,883) and non-BS-GPS ( n = 308,988) cohorts. The LOS and rate of LLOS between the BS-GPS and non-BS-GPS cohorts and between subcohorts with and without clinically significant anxiety and/or depression (CSAD, i.e., HEI score ≥11 on admission to the hospital) in the BS-GPS cohort were compared using univariable analyses, multilevel analyses, and/or propensity score-matched analyses, respectively. RESULTS: The detection rate of CSAD in the BS-GPS cohort varied from 2.64% (95% confidence interval [CI]: 2.49%-2.81%) to 20.50% (95% CI: 19.43%-21.62%) across the 20 departments, with a average rate of 5.36%. Significant differences were observed in both the LOS and LLOS rates between the subcohorts with CSAD (12.7 days, 535/9590) and without CSAD (9.5 days, 3800/169,293) and between the BS-GPS (9.6 days, 4335/178,883) and non-BS-GPS (10.8 days, 11,483/308,988) cohorts. These differences remained significant after controlling for confounders using propensity score-matched comparisons. A multilevel analysis indicated that BS-GPS was negatively associated with both LOS and LLOS after controlling for sociodemographics and the departments of patient discharge and remained negatively associated with LLOS after controlling additionally for the year of patient discharge. CONCLUSION Emotional distress significantly prolonged the LOS and increased the LLOS of non-psychiatric inpatients across most departments and general hospitals. These impacts were moderated by the implementation of BS-GPS. Thus, BS-GPS has the potential as an effective, resource-saving strategy for enhancing mental health care and optimizing medical resources in general hospitals.

OBJECTIVES: To investigate the effect of high glucose on macrophage polarization and the role of immune-responsive gene 1 (IRG1) in mediating its effect. METHODS: RAW264.7 cells were transfected with IRG1-overexpressing plasmid or IRG1 siRNA via electroporation and cultured in either normal or high glucose for 72 h to observe the changes in cell viability and morphology using CCK-8 assay and phase contrast microscopy. The protein levels of IRG1, iNOS, Arg-1, IL-1β and IL-10 in the treated cells were detected with Western blotting, and the fluorescence intensities of iNOS and Arg-1 were detected using immunofluorescence assay. The protein levels of IL-1β and IL-10 in the culture medium were determined with ELISA. RESULTS: High glucose exposure significantly reduced IRG1 and Arg-1 expressions, increased iNOS and IL-1β expressions and IL-1β secretion, and decreased IL-10 level in RAW264.7 cells. Transfection with the IRG1-overexpressing plasmid provided the cells with obvious resistance to high glucose-induced changes in iNOS, Arg-1, IL-1β and IL-10, whereas IRG1 knockdown further enhanced the effects of high glucose exposure on Arg-1 expression and the expression and secretion of IL-10. CONCLUSIONS High glucose promotes M1 polarization of the macrophages possibly through a mechanism to inhibit the expression of IRG1 protein, thus leading to chronic inflammatory response.

Objective:To explore the efficacy and safety of supplementing early rehabilitation with local vibration therapy in the prevention and treatment of ICU-acquired weakness (ICU-AW).Methods:Ninety-six critically ill patients were randomly divided into a control group, a rehabilitation group, and a combination group, each of 32. All received routine treatment and care, but the rehabilitation group and the combination group received earlier rehabilitation and the combination group early rehabilitation + local vibration therapy. Before and after 2 weeks of the treatments, the incidence of ICU-AW was recorded, Acute Physiology and Chronic Health Evaluation II (APACHE-II) scoring was performed and ultrasound was used to detect the rehabilitation effect. The incidence of adverse events was also recorded.Results:The incidence of ICU-AW was significantly lower in the combination group than among the rehabilitation group, while that of the rehabilitation group was significantly lower than among the control group. The APACHE II scores showed the same progression. The thickness, cross-sectional area, muscle echo, and diaphragm thickness and activity of the rectus femoris, rectus abdominis, and biceps brachii muscles in the combination group were, on average, significantly better than among the rehabilitation group, but with the rehabilitation group′s results significantly better than among the control group. The average mechanical ventilation time and ICU stay of patients in the combination group were significantly shorter than the rehabilitation group′s averages, which in turn were significantly shorter than those of the control group. The combination group′s average Barthel Index after the experiment was significantly higher than that of the rehabilitation group, which was in turn significantly higher than the control group′s average. The incidence of adverse events in the combination group was significantly lower than in the rehabilitation group, with that of the latter significantly lower than among the control group.Conclusions:Combining local vibration therapy with early rehabilitation is beneficial for the safe prevention and treatment of ICU-AW.

BACKGROUND:Zinc-based alloy medical implant materials have excellent mechanical properties,complete degradability and good biocompatibility,and are mainly used in orthopedic implants,cardiovascular stents,bile duct stents,tracheal stents,nerve catheters,etc. OBJECTIVE:To review the research progress of biodegradable zinc-based alloys in bone defect repair and prospect the promising research direction and achievements of zinc-based materials. METHODS:After searching PubMed,Web of Science,WanFang Data,and CNKI databases from the establishment of the database to June 2023,various relevant articles on biodegradable zinc-based alloys for bone implant material research were collected.The basic characteristics of biodegradable zinc based alloys were summarized,and the role of zinc-based alloys in promoting bone tissue repair was sorted and summarized.The current research hotspots and shortcomings were discussed. RESULTS AND CONCLUSION:(1)Zinc-based alloys have good biocompatibility.Using zinc-based alloys as the matrix material,with the help of scaffold structure construction technology and coating optimization process,the bone conductivity of zinc-based alloys will be effectively improved,and their degradation products will have efficient bone induction to regulate the gene expression of osteoblasts and osteoclasts,thereby promoting the repair and reconstruction of bone defects.(2)However,in the research on optimizing zinc-based alloys,the coating process is relatively insufficient,and additive loading technology is still lacking.(3)Zinc-based alloys have excellent mechanical and biological properties.Through special processes,their bone conductivity and osteoinductivity can be increased to effectively improve their ability to promote bone repair and reconstruction,and it is expected to further achieve the development of personalized transplant materials.Further research and development are needed to optimize the integration of coating and additive loading technologies into zinc-based alloys.

Objective To explore the mechanism of the thioredoxin-interacting protein(TXNIP)/thioredoxin-1(Trx-1)pathway in regulating the polarization of retinal microglia in rats after retinal ischemia-reperfusion(RIR)in rats,and to provide new ideas for the prevention and treatment of retinal ischemia reperfusion injury(RIRI).Methods For-ty-two healthy adult male Sprague-Dawley rats were randomly divided into a Sham group,a RIRI group and a TXNIP siRNA group.The right eye of the rats was experimented.For RIRI and TXNIP siRNA groups,RIRI models were established using the anterior chamber high intraocular pressure method.Rats in the TXNIP siRNA group were given the intravitreal injection of TXNIP siRNA 3 d before modeling.Hematoxylin-eosin(HE)staining was used to analyze retinal histopathologic changes of rats in all groups 24 h after modeling.Immunohistochemical staining of brain-specific homeobox/POU domain proteins 3A(Brn-3a)was made to count the number of retinal ganglion cells(RGCs).The dynamical changes in the number of TXNIP+cells 6 h,24 h,72 h and 7 d after modelling were analyzed through immunohistochemical staining in the RIRI group.The retinal microglia polarization and changes in the expression of TXNIP and Trx-1 proteins in each group were de-tected by double immunofluorescence staining and Western blot 24 h after modeling.Results HE staining results showed that 24 h after modelling,the retinal cells were disordered and the inner retinal layer was thickened and swelled in RIRI and TXNIP siRNA groups,compared with those in the Sham group(all P＜0.05).Immunohistochemical staining results of Brn-3a showed that 24 h after modeling,the number of Brn-3a+cells in RIRI and TXNIP siRNA groups significantly decreased,compared with that in the Sham group(both P＜0.05).The number of Brn-3a+cells in the TXNIP siRNA group was signifi-cantly higher than that in the RIRI group(P＜0.05).Immunohistochemical staining results of TXNIP at different time points after modeling showed that the expression of TXNIP+proteins started to increase 6 h after modeling.The TXNIP+protein level reached a peak at 24 h and then decreased gradually.Western blot results revealed that 24 h after modeling,RIRI and TXNIP siRNA groups had significantly higher TXNIP levels and significantly lower Trx-1 levels than the Sham group(all P＜0.05).Compared with those in the RIRI group,the expression of TXNIP proteins was significantly lower and the expression of Trx-1 proteins was significantly higher in the TXNIP siRNA group(both P＜0.05).Double immunofluores-cence staining showed that 24 h after modeling,Iba1+/CD206+cells were significantly more and Iba1+/CD16+cells were significantly less in the TXNIP siRNA group than those in the RIRI group(both P＜0.05).RIRI and TXNIP siRNA groups had significantly more Ibal+/TXNIP+cells and significantly less Iba1+/Trx-1+cells than the Sham group(both P＜0.05).The number of Iba1+/TXNIP+cells was significantly lower and the number of Iba1+/Trx-1+cells was significantly higher in the TXNIP siRNA group than those in the RIRI group(both P＜0.05).Conclusion RIR activates the TXNIP/Trx-1 path-way to induce the activation of retinal microglia and regulate the polarization of microglia,thereby resulting in RIRI in rats.

Objective To investigate the relationship between calcium-sensing receptor(CaSR)gene rs17251221,rs60388563 loci polymorphisms and the genetic susceptibility of breast cancer(BC).Methods A total of 122 patients with breast cancer admitted to Hengshui Second People's Hospital from January 2022 to June 2024 were selected as the BC group,and 100 healthy women without blood relationship at the same time were selected as the control group.The polymorphisms of CaSR gene rs17251221,rs60388563 loci were detected by polymerase chain reaction(PCR).The clinical data,genotype distribution and allele frequency were compared between the two groups.Non-conditional Logistic regression model was used to analyze the correlation between CaSR gene polymorphism and genetic susceptibility of BC patients.Results Comparing the general data of the two group,the proportion of family history of cancer in the BC group was significantly higher than that in the control group,and the difference was statistically significant(t=12.246,P<0.05).The genotype distribution of CaSR gene rs17251221 and rs60388563 loci in the control group and the BC group was consistent with the Hardy-Weinberg equilibrium law(χ2=0.087～1.202,P＞0.05),which was representative of the population.Under the co-dominant model of rs17251221 and rs60388563 loci,the risk of BC in GG genotype was significantly increased(OR=1.493,95%CI=1.070～2.108;OR=1.483,95%CI=1.034～2.121).Under the dominant model(AA vs GA+GG)and recessive model(GG vs GA+AA),the rs17251221 locus carrying G allele(OR=1.371,95%CI=1.023～1.824)and A allele(OR=0.524,95%CI=0.221～0.926)was significantly associated with the risk of BC(P<0.05).Under the dominant model(CC vs GC+GG)and recessive model(GG vs GC+CC),the rs60388563 locus carrying G allele(OR=1.245,95%CI=1.107～1.461)and C allele(OR=0.682,95%CI=0.523～0.974)was significantly associated with the risk of BC(P<0.05).Conclusion The rs17251221,rs60388563 loci polymorphisms of CaSR gene are closely related to BC susceptibility,and the risk of BC is high in individuals carrying G allele.

Objective To explore the regulatory effect of moderate intensity aerobic exercise on glu-cose and lipid metabolism disordersafter immune stimulation in high-fat diet induced insulin resistance(IR)mice by inducing tolerance of trained immunity.Methods Eighteen of 70 male C57BL/6 male mice were randomly selected as the control group(CON group),while the remaining mice were subjected to high-fat diet intervention(HFD group)for 8 weeks.After modeling,six of the CON group and HFD group were measured their glucose and lipid metabolism and inflammation levels.The remaining mice in the HFD group were randomly divided into HFD sedentary group(HS group)and HFD exer-cise group(HE group),each of 16.The HE groups underwent a daily 60-minute running on a hori-zontal treadmill at 12 m/min,5 days a week for 8 weeks.After that,the CON,HS and HE groups were randomly divided into an immune stimulation group(lipopolysaccharides,LPS group)and a con-trol group(phosphate buffered saline,PBS group),with 6 in CON-PBS and CON-LPS groups,and 8 in HS-PBS,HS-LPS,HE-PBS and HE-LPS groups.The LPS group received intraperitoneal injec-tion of LPS as an immune stimulus,and were taken samples 24 hours after intervention.During the intervention period,the body weight,food intake,fasting blood glucose(FBG),glucose tolerance,and insulin tolerance were tested for all groups.Then,the serum blood lipid level was tested.More-over,the levels of tumor necrosis factor-α(TNF-α),interleukin-1 β(IL-1β)and interleukin-10(IL-10)in serum were detected by using the enzyme-linked immunosorbent assay,while the protein expression of IL-1β,IL-10,induciblenitricoxidesynthase(iNOS)andarginase-1(Arg-1)were measured by using Western Blot.Results(1)After 8 weeks of high-fat diet intervention,compared with the CON group,there was a significant increase in the body weight,food intake,and FBG,the level of TNF-α and IL-1β in serum and expressions of IL-1β and iNOS in liver,skeletal muscle and adipose tissue,but a significant decrease in glucose and insulin tolerance,the level of anti-in-flammatory factor IL-10,as well as IL-10 and Arg-1 in liver and Arg-1 in adipose tissues in group HFD(P<0.01,P<0.05).(2)After 8 weeks of diet intervention,the body weight of group HS-PBS was still significantly higher than group CON-PBS(P<0.01).However,no significant differences were found between group CON-PBS and HS-PBS in other indicators(P>0.05).After LPS intervention,the food intake of both CON-LPS and HS-LPS groups was significantly lower than the corresponding PBS group(P<0.05).However,the levels of FBG,TG,TC,LDL-C,TNF-α and IL-1β in serum,IL-1β and iNOS in liver and adipose tissues,and iNOS in skeletal muscles of group HS-LPS were signif-icantly higher compared with group HS-PBS and CON-LPS(P<0.05).Meanwhile,the levels of IL-10 in serum,skeletal muscles and adipose tissues,and Arg-1 in skeletal muscles and adipose tissues of group HS-LPS decreased significantly compared with group HS-PBS and CON-LPS(P<0.05).(3)Af-ter simultaneous aerobic exercise intervention,there were no significant differences between group HE-LPS and HE-PBS in FBG,TC,LDL-C,TNF-α,IL-1β and IL-10 in serum,as well as IL-1β,iN-OS and IL-10 in the liver,skeletal muscles and adipose tissues(P>0.05).Moreover,thelevels of FBG,TG,TC,TNF-α,IL-1β in serum,and IL-1β and iNOS in the liver,skeletal muscle and adi-pose tissue decreased significantly in group HE-LPS compared with group HS-LPS(P<0.05).Howev-er,the levels of IL-10 in the serum and liver,and IL-10 and Arg-1 in skeletal muscles and adi-pose tissues increased significantly in group HE-LPS compared with group HS-LPS(P<0.05).Conclu-sion Eight-week aerobic exercise can effectively relieve the glucose and lipid metabolism disorder after immune stimulation in IR mice,which may be related to the stimulation of immunologic tolerance in innate immune cells,thereby reducing the excessive inflammatory response caused by secondary im-mune stimulation.
