ObjectiveMicrotube associated protein-2 （MAP-2）， alpha-tubulin （α-tubulin）， and synaptophysin （SYP） are important proteins in neuronal signal communication. This paper observed the effects of modified Zhigancao Tang on the expression of serum α-Synuclein （α-Syn） and its oligomers， MAP-2， α-tubulin， and SYP of patients with liver and kidney deficiency of Parkinson's disease （PD）， analyzed their correlation， and evaluated the therapeutic effect of modified Zhigancao Tang in patients with liver and kidney deficiency of PD based on α-Syn transmission pathway mediated by neuronal communication in vivo. MethodsA total of 60 patients with PD who met the inclusion criteria were randomly divided into a treatment group （30 cases） and a control group （30 cases）. Both groups were treated on the basis of PD medicine， and the treatment group was treated with modified Zhigancao Tang. Both groups were treated for 12 weeks. The changes in UPDRS score， TCM syndrome score， and expression of serum α-Syn and its oligomers， MAP-2， α-tubulin， and SYP were observed before and after 12 weeks of treatment in each group. The correlation between the above-mentioned serum biological indexes and the levels of serum α-Syn and its oligomers was analyzed. ResultsAfter treatment， the TCM syndrome score， UPDRS score， UPDRS-Ⅱ score， and UPDRS-Ⅲ score of the treatment group were significantly decreased （P<0.05， P<0.01）. The UPDRS score， UPDRS-Ⅱ score， and UPDRS-Ⅲ scores in the treatment group were significantly decreased compared with those in the control group after treatment （P<0.05）. After treatment， the total effective rate of the control group was 63.3% （19/30）， and that of the treatment group was 86.7% （26/30）. The clinical effect of the observation group was better than the control group （Z=-2.03， P<0.05）. The total effective rate of the observation group was better than that of the control group， and the difference was statistically significant （χ²=5.136， P<0.05）. After treatment， the oligomer level of serum α-Syn and MAP-2 level in the treatment group were significantly decreased （P<0.05， P<0.01）. The levels of serum α-Syn and its oligomers， as well as α-tubulin in the treatment group， were significantly decreased compared with those in the control group after treatment （P<0.05， P<0.01）. Serum α-Syn was correlated with serum MAP-2 and α-Syn oligomer in patients with PD （P<0.05， P<0.01） but not correlated with serum SYP . Serum α-Syn oligomers of patients with PD were correlated with serum MAP-2 and α-tubulin （P<0.05， P<0.01） but not correlated with serum SYP level. Serum SYP of patients with PD was correlated with serum MAP-2 （P<0.05）. ConclusionModified Zhigancao Tang has a therapeutic effect on patients with liver and kidney deficiency of PD by inhibiting the production of α-Syn oligomers and intervening α-Syn microtubule transport pathway in vivo.

Objective:To evaluate the clinical efficacy of Xiaoxuming Decoction combined with conventional Western medicine therapy in the treatment of patients with ischemic stroke in the recovery period.Methods:A randomized controlled clinical study was conducted. A total of the 118 patients with wind phlegm obstructing collaterlas syndrome during the recovery period of ischemic stroke in our hospital from September 2023 to July 2024 were selected as the observation subjects. They were divided into two groups using a random number table method, with 59 patients in each group. The control group was treated with conventional Western medicine therapy, while the TCM group was treated with modified Xiaoxuming Decoction on the basis of the control group. Both groups were treated for 2 months and followed up for 1 month. TCM syndrome scoring was performed before and after treatment, Barthel Index was used to evaluate daily living ability, and carotid artery ultrasound detector was used to evaluate the stability of carotid vascular plaques. Inter group comparisons were performed using t test, χ2 test, or repeated measures analysis of variance (RM-ANOVA). Results:RM-ANOVA showed that the time effect and inter group effect of TCM syndrome integration in the TCM group were significantly different from those in the control group ( Ftime=55.56, Ptime<0.001); Fbetween=18.94, Pbetween<0.001); there was no statistical significance in the interaction effect compared to the control group ( Finteraction=0.24, Pinteraction=0.866); the time effect, inter group effect, and interaction effect of Barthel Index in the TCM group were significantly different from those in the control group ( Ftime=44.57, Ptime<0.001); Fbetween=18.94, Pbetween<0.001; Finteraction=7.45, Pinteraction<0.001). The number of patients with unstable plaques in the TCM group after 3 months of treatment was lower than that in the control group ( χ2=4.52, P=0.033). Conclusion:The combination of modified Xiaoxuming Decoction and conventional Western medicine therapy can effectively improve the clinical symptoms and daily living ability of patients in the recovery period of ischemic stroke, improve the stability of cervical vascular plaques, and the clinical efficacy becomes more significant over time.

ObjectiveTo explore the mechanism of Buzhong Yiqitang in ameliorating inflammatory injury in autoimmune thyroiditis (AIT) mice based on the Toll-like receptor 4（TLR4）/nuclear transcription factor-kappa B（NF-κB）/absent in melanoma 2（AIM2）inflammasome signaling pathway. MethodThe 120 genetically susceptible 8-week-old NOD.H-2^h4 mice were selected and randomly divided into control group， model group， low， medium and high dose groups of Buzhong Yiqitang （4.78， 9.56， 19.12 g·kg^-1）， and western medicine group （selenium yeast tablets， 3.033×10^-5 g·kg^-1）. The AIT model mice in each group drank ad libitum 0.05% sodium iodide aqueous solution for 8 weeks to establish the AIT model， and the control group drank ad libitum distilled water. Eight weeks later， the mice in each dosing group were divided into groups and gavage. The swelling of thyroid tissue was observed with the naked eye， and the weight of spleen was weighed. The content of serum inflammatory factors interleukin-1β （IL-1β）， interleukin-6 （IL-6）， tumor necrosis factor-α （TNF-α） was measured by enzyme-linked immunosorbent assay （ELISA）， and Real-time PCR was used to detect the expression of HMGB1， TLR4， AIM2， NF-κB p65，apoptosis-associated speck-like protein（ASC），cysteinyl aspartate-specific protease-1（Caspase-1）， IL-1β mRNA. Western blot was used to detect the expression of high motility group protein 1 （HMGB1）， TLR4， AIM2， NF-κB p65， phosphorylation（p）-NF-κB p65， ASC， Caspase-1， and IL-1β proteins in thyroid tissue， and immunofluorescence staining was used to observe the protein expression of HMGB1， AIM2， and NF-κB p65 in thyroid tissue of mice. ResultCompared with the control group， the thyroid tissue of mice in the model group was significantly swollen， the spleen quality was significantly increased， and the expression of HMGB1， TLR4， NF-κB p65， AIM2， ASC， Caspase-1， IL-1β in thyroid tissue was significantly increased （P<0.01）. Compared with the model group， the swelling of thyroid tissue in mice in each dose group of Buzhong Yiqitang was improved， the quality of spleen was significantly reduced， and the expression of HMGB1， TLR4， AIM2， NF-κB p65， p-NF-κB p65， ASC， Caspase-1， IL-1β in thyroid tissue was significantly reduced （P<0.05， P<0.01）. ConclusionBuzhong Yiqitang can effectively improve the inflammatory injury of AIT， and regulating the abnormal activation of the TLR4/NF-κB/AIM2 inflammasome signal pathway may be one of its intervention mechanisms.

AIM:To test and compare the perceptual eye position and fixation stability of adolescents with emmetropia and adolescents with low myopia, investigating the characteristics of the perceptual eye position and fixation stability of adolescents with low myopia.METHODS: Cross-sectional study. A total of 132 adolescents(264 eyes)who visited in the ophthalmology clinic of our hospital from April to December 2023 were randomly selected as the research subjects. Participants were categorized into normal control group(n=45, 90 eyes), simple low myopia group(n=45, 90 eyes)and low myopia with anisometropia group(n=42, 84 eyes)according to their refractive status and were underwent assessments for perceptual eye position and fixation stability.RESULTS: Compared with the normal control group, the static and dynamic horizontal perceptual eye position deviation of the simple low myopia group and the low myopia with anisometropia group were significantly increased(P<0.05). Compared with the simple low myopia group, the static and dynamic horizontal perceptual eye position deviation of the low myopia with anisometropia group were significantly increased(P<0.05). There was no significant difference in static and dynamic vertical perceptual eye position deviation among the three groups(P>0.05); compared with the normal control group, the horizontal and vertical fixation stability of the simple low myopia group and the low myopia with anisometropia group were significantly worse(all P<0.01), but there was no differences in the simple low myopia group and the low myopia with anisometropia group(P >0.05).CONCLUSION: Abnormalities are observed in perceptual eye position and fixation stability function in adolescents with low myopia compared with those adolescents with emmetropia, even at best corrected visual acuity. The occurrence of anisometropia could lead to an increased degree of horizontal perceptual eye position displacement.

Objective To investigate the preparation and evaluation of animal models of depression associated with autoimmune thyroiditis,and to verify the NLRP3/Caspase-1/GSDMD pathway based on this condition.Methods 32 NOD.H-2H4 mice were randomly divided into a normal(N)group,depression(DP)group,autoimmune thyroiditis with depression(AIT+DP)group,autoimmune thyroiditis(AIT)group,with 8 animals in each group.The N group was fed normally,the DP group was subjected to chronic unpredictable mild stress(CUMS)for 5 weeks,the AIT group was given 0.05％sodium iodide water to establish an autoimmune thyroiditis model,and the AIT+DP group was subjected to 5 weeks of CUMS to establish the AIT animal model.We evaluated whether the mouse autoimmune thyroiditis model had been successfully prepared by observing the thyroid tissue structure,lymphocyte infiltration,and serum TGAb and TPOAb levels.Changes in body weight,sugar water preference rate,open field behavior(central quadrant time,central quadrant time proportion,standing rate,frequency of defecation,and hair grooming time),and hippocampal pathological changes were used to evaluate the depression status of the mice.When the model mice met the above-mentioned indicators related to depression and autoimmune thyroiditis,the AIT+DP animal model was considered successfully prepared.Results Compared with the levels in the N group,the AIT group's and AIT+DP group's serum TGAb and TPOAb levels were significantly increased(P＜0.01),and a large number of inflammatory cells had infiltrated the thyroid gland.The central quadrant time and central quadrant time proportion,standing rate,frequency of defecation,and hair grooming time were reduced to varying degrees in the DP group and AIT+DP group.In addition,the numbers of glial cells in the cerebral cortex increased and neuronal cells decreased,accompanied by some nuclear atrophy,and the expression levels of NLRP3,IL-1β,Caspase-1,and GSDMD-N significantly increased,especially in the AIT+DP group(P＜0.01).Conclusions 0.05％sodium iodide water and CUMS create autoimmune thyroiditis with depression model animals that better simulate the external performance and internal index changes of the diseases.These mice can provide an animal model reference for research into autoimmune thyroiditis with depression.

Objective:To evaluate A modified Blumgart pancreaticojejunostomy in laparoscopic pancreaticoduodenectomy.Methods:The clinical data of 81 patients undergoing laparoscopic pancreaticoduodenectomy in Zhengzhou University Affiliated Cancer Hospital from Jan 2019 to Jan 2022 were retrospectively analyzed. Among them, 26 patients underwent modified Blumgart anastomosis and 55 underwent conventional Blumgart anastomosis.The data of demographics, liver function, pancreatic texture, operational result and complications were compared between the two groups.Results:The preoperative data (body mass index, preoperative albumin, prealbumin, transaminase, total bilirubin) between two groups were comparable ( P>0.05). There was no significant difference in pancreatic texture, pancreatic duct diameter and intraoperative blood loss between the two groups ( P>0.05). The modified group had shorter total operation time ( P<0.05), shorter pancreaticojejunostomy time ( P<0.05), shorter postoperative hospital stay ( P<0.05). The incidence of total pancreatic fistula and biochemical fistula in the modified group were lower than those in the conventional group ( P<0.05). There was no significant difference in the incidence of B/C grade pancreatic fistula and bile leakage, postoperative bleeding, infection and delayed gastric emptying between the two groups ( P>0.05). Conlusions:The modified Blumgart pancreaticojejunostomy during laparoscopic pancreaticoduodenectomy is safe, easy to do and time saving. While the incidence of postoperative pancreatic fistula with clinical significance　and other major complications were similar to traditional Blumgart procedure.

ObjectiveTo investigate the effect and mechanism of Dahuang Zhechongwan （DHZCW） on adenine-induced renal fibrosis in rats from the perspective of intestinal flora. MethodThirty-six SD rats were randomly divided into a blank group， a model group， and high-， medium- and low-dose DHZCW groups （0.168， 0.084， 0.042 g·kg^-1）， and a pirfenidone group （200 mg·kg^-1）， with 6 rats in each group. Except for those in the blank group， rats in other groups were treated with adenine suspension （250 mg·kg^-1） by gavage for 28 days for renal fibrosis model induction. Subsequently， they received drug intervention for 4 weeks. Urine samples were collected from rats in metabolic cages， and renal function indicators including blood urea nitrogen （BUN）， urea， creatinine （Crea）， cystatin C （Cys C）， and 24-hour urine protein （24 h TP） were measured. Kidney samples were collected and subjected to hematoxylin-eosin （HE） staining and Masson's trichrome staining to observe the pathological changes in rat renal tissues. Western blot was used to detect the expression levels of key effector proteins α-smooth muscle actin （α-SMA）， type Ⅰ collagen （ColⅠ）， and type Ⅲ collagen （ColⅢ） in the kidneys. High-throughput sequencing of 16S rDNA was used to analyze the species diversity of rat intestinal flora. ResultCompared with the blank group， the model group showed increased BUN， urea， Crea， Cys C， and 24 h TP levels （P<0.01）. Compared with the model group， the high-， medium-， and low-dose DHZCW groups， as well as the pirfenidone group， showed significant reductions in BUN， urea， Crea， Cys C， and 24 h TP levels （P<0.01）， indicating that DHZCW intervention significantly improved renal function. In the model group， renal tissues exhibited significant fibrotic changes， and the protein levels of α-SMA， ColⅠ， and ColⅢ were significantly increased （P<0.01） compared to those in the blank group. Compared with the model group， the high-dose DHZCW group and the pirfenidone group had relatively normal tissue structure， with no significant pathological damage observed. However， fibrotic changes were observed in the medium- and low-dose DHZCW groups， with the changes being more significant in the low-dose group. The protein levels of α-SMA， ColⅠ， and ColⅢ were significantly decreased in the high-， medium-， and low-dose DHZCW groups， as well as the pirfenidone group （P<0.01）， indicating that DHZCW effectively reduced abnormal collagen deposition and inhibited renal fibrosis. From the perspective of intestinal flora， at the phylum level， compared with the blank group， the model group showed a significant increase in the abundance of Firmicutes and a decrease in Bacteroidetes， leading to a significant imbalance in their ratio. At the family level， the model group decreased the abundance of Lachnospiraceae， Prevotellaceae， and Bacteroidota_unclassified， and increased the abundance of Ruminococcaceae， Lactobacillaceae， and Oscillospiraceae. At the genus level， the model group showed significantly reduced abundance of Firmicutes_unclassified， Bacteroidota_unclassified， and Prevotellaceae_UCG-001， etc.， and increased abundance of UCG-005， Clostridia_UCG-014_unclassified， etc. Compared with the model group， DHZCW effectively reduced the abundance of potential pathogenic bacteria and increased the abundance of beneficial bacteria， regulating the intestinal flora. ConclusionDHZCW can effectively improve renal function and inhibit renal fibrosis， and its mechanism of action may be related to the regulation of intestinal flora.

Monoclonal antibody drugs that inhibit programmed death 1 (PD-1) or programmed death ligand 1 (PD-L1) have been widely used in esophageal cancer (EC) and yielded significant therapeutic responses. However, only a few patients obtain lasting clinical benefits due to primary or acquired drug resistance, and new treatment schemes are urgently needed. The tumor immune microenvironment is the main factor that affects patients' response to immunosuppressive agents. This article will discuss the role of immunosuppressive cells and non-cellular components in the immune process to provide ideas for the next research direction of EC.

Objective:To analyze the effect of different lithotomy positions on hemodynamics in patients undergoing laparoscopic total hysterectomy.Methods:A total of 50 patients who underwent laparoscopic total hysterectomy at Zhoushan Women and Children's Hospital between January 2020 and June 2021 were included in this study. The patients were randomly divided into a control group and an observation group using a random number table method, with 25 patients in each group. The control group underwent conventional lithotomy position total laparoscopic hysterectomy, while the observation group underwent high and low lithotomy position total laparoscopic hysterectomy. The general surgical indicators, respiratory function indicators, blood gas analysis indicators, hemodynamic levels, incidence of complications, and clinical efficacy were compared between the two groups.Results:The general surgical indicators and airway peak pressure indicators in the observation group were significantly lower than those in the control group (both P < 0.05). There was no statistically significant difference in partial pressure of end-tidal carbon dioxide (PCO 2) and arterial carbon dioxide partial pressure (PaCO 2) between the two groups (both P < 0.05). At 15 minutes after pneumoperitoneum, the PaCO 2 level increased in each group, and the PaCO 2 level in the observation group was significantly higher than that in the control group (all P < 0.05). At the same time, the HCO 3- level decreased in each group, and the HCO 3- level in the observation group was significantly lower than that in the control group (all P < 0.05). At 5 minutes before recovery of body position, heart rate, systolic blood pressure, and diastolic blood pressure in the control group were (76.52 ± 8.61) beats/minute, (113.52 ± 5.36) mmHg (1 mmHg = 0.133 kPa), and (86.91 ± 4.21) mmHg, respectively. At 5 minutes after recovery of body position, heart rate, systolic blood pressure, and diastolic blood pressure in the control group were (89.52 ± 8.61) beats/minute, (106.85 ± 5.63) mmHg, and (80.96 ± 3.65) mmHg, respectively. At 5 minutes before recovery of body position, heart rate, systolic blood pressure, and diastolic blood pressure in the observation group were (76.36 ± 8.61) beats/minute, (112.79 ± 5.28) mmHg, and (86.89 ± 4.54) mmHg. At 5 minutes after recovery of body position, heart rate, systolic blood pressure, and diastolic blood pressure in the observation group were (75.63 ± 6.86) beats/minute, (111.99 ± 5.51) mmHg, and (85.06 ± 3.21) mmHg, respectively. At 5 minutes after recovery of body position, heart rate in the control group was increased and that in the observation group was decreased compared with heart rate measured at 5 minutes before recovery of body position. At 5 minutes after recovery of body position, heart rate in the observation group was significantly lower than that in the control group. Diastolic blood pressure and systolic blood pressure decreased in each group, and the amplitudes of reductions in diastolic blood pressure and systolic blood pressure in the observation group were significantly lower than those in the control group. ( t = 6.04, 3.26, 4.22, all P < 0.05). There was no statistically significant difference in incidence of adverse reactions between the two groups ( P > 0.05). The overall response rate in the observation group was significantly higher than that in the control group ( P < 0.05). Conclusion:Compared with conventional lithotomy position total laparoscopic hysteretsotomy, high and low lithotomy position total laparoscopic hysterectomy takes a shorter duration for total laparoscopic hysterectomy, leads to a shorter length of hospital stay, results in less blood loss, causes fewer postoperative infections, and results in more stable hemodynamics and a lower incidence of complications.

To investigate the efficacy and safety of total oral regimen containing ixazomib in multidrug-resistant relapsed and refractory multiple myeloma(RRMM). A total of 38 patients were retrospectively analyzed from August 2018 to January 2020 in the First Affiliated Hospital of Soochow University. The overall response rate (ORR)was 36.8%. Among them, the very good partial response (VGPR) or better rate was 23.7%, and the complete response (CR) rate was 5.3%. The ORR was 41.7% in patients receiving ixazomib-lenalidomide-dexamethasone (IRD) regimen. Median PFS was 5 months and median OS was 7.5 months. The ORR was 50% after second-line therapy, 40% after third-line therapy and 12.5% after forth-line therapy or more. The ORR was 29.0% in bortezomib-refractory patients, 38.0% in lenalidomide-refractory patients, 21.4% in bortezmoib & lenalidomide dual refractory patients. Grade 3-4 hematological adverse events (AEs) were reported in 21% patients. Common hematological AEs included lymphopenia, neutropenia, thrombocytopenia. Other usual AEs were fatigue and diarrhea. No grade 3-4 peripheral neuropathy was recorded. In the treatment of relapsed/refractory multiple myeloma patients with multidrug resistance, the total oral regimens containing ixazomib demonstrate reliable efficacy and safety. Early administration of ixazomib at first or second relapse is suggested for more favorable clinical outcome.
